Description

Mobile plant

The present invention relates to a kind of mobile plant of specification of the satisfied vehicle that can on highway, travel, especially relate to that a kind of kinds of goods that can finish various preparations processing comprise the raw material of industry of coke for example and as building waste, the various waste products of bottle, jar etc. carry out the mobile plant such as fragmentation or screening operation.

At one as the various raw materials of industry, for example in the mine in the source of ferroalloy, iron ore or rock phosphate in powder, the manufacturing works, thisly become the block raw material of industry need be, be sent to harbour that a shipment starts shipment then or directly give the user with truck or train through broken.Usually be that material is broken less than the best granular size that is suitable for transporting in this case, and like this size distribution of the broken raw material of industry at fine powder to the scope of the bulk of above-mentioned the best size, and this and the desired size distribution of user are inconsistent usually.In addition, to stack through various carryings through the broken raw material of industry, just can be admitted in the end-user device that for example resembles smelting furnace or the blast furnace, material may be damaged therebetween, thereby increased fine powder and fine grain quantity, but also can mix danger as external foreign matters such as stone wood chips.Therefore, the size distribution that must make this raw material of industry be consistent so that its raw material unload by ship or vehicle transport drop on the storage house to send into this section of subscriber equipment at last to raw material during in any stage all meet the desired particle size distribution of user, thereby just need a kind of equipment that can finish broken for the second time and screening.

In addition, when transportation comprises graininess agricultural product as wheat and this class cereal of rice, during material is carried repeatedly and stacked, have the danger that more particle takes place and mix the exogenous impurity particle, therefore just be necessary once to screen operation sometimes to remove these particles and exogenous impurity particle.

Also have, its content is still stayed in the container if bottled or canned Food ﹠ Drink, medicine and so on need to handle, and these containers must be broken in this wise, its content can be separated and be reclaimed.

In the past, actual conditions are such, in order to carry out this fragmentation and screening operation, the special-purpose disintegrating machine of single goal setting and screening machine be used as permanent plant and use for will permanently fixedly mount in their factory of needs or similar site, and be in coarse grain broken and middle grain fragmentation or the fine crushing each, and screen or particulate each in sieving all will be provided with such special purpose machinery for coarse grain screening and middle.

With regard to the situation of the size distribution of the desired coke of foregoing user, be used for the coke example of blast furnace, can keep suitable voidage and can be therebetween in order to make coke as a thermal source and reducing agent, its optimal granular size is considered to should be between about 20 to 50mm, but in the example of foundry coke, for in the air mass flow of its per unit cross-sectional area and metal molten rate all than blast furnace being makes coke keep needed voidage therebetween and as heating and carburant usefulness in the high smelting furnace, its optimal granular size should than blast-furnace coke be big, be selected in and be approximately 1/8 to 1/12 of smelting furnace internal diameter; More particularly then be the coke of various granular sizes, for example 60 to 80mm, and 80 to 120mm or all needing greater than 120mm.In addition, at a manufacturing such as Antaciron, then using granular size in the example of the ferroalloy coke of using as the resistance heated reducing agent in the electric furnace of ferroalloy such as ferromanganese or ferrochrome is 10 to 30mm coke, and being the coke of about 30mm, granular size is used for carbon, for example in the carbon monoxide gas equalization of coal, the coke of various variable grain sizes in addition then is used for calcium carbide according to the kind of the stove that uses coke, lime calcining, manufacture of cement and the such purpose of heating.

Up to now, for example the material of the coke that produces from coking plant or ore of being shipped by cargo ship and so on is to be sent to various types of disintegrating machines of permanent plant form, follow the particle that this material is fractured into suitable size, this then material is again through screening, the product of oversize returns again in the disintegrating machine, and the product that belongs to proper granular size scope is then collected by the machine of ribbon conveyer and so on.The coke of the proper granular size of these collections transport by the car of truck and so on and weighing after, just be stored in the sorting depot of factory.This product is directly given the user by truck again from the warehouse, perhaps product is lightered one and transported on the ship, gives the user by truck again after the ship navigation.

As previously mentioned, because conventional disintegrating machine and screening machine are to be contained in regularly in the workshop in, just must be specially kinds of goods that some specific preparation is processed be provided with a plurality of disintegrating machines and screening machine and need one broader place as the place of permanent installation site and management.

In addition, because conventional disintegrating machine and screening machine are special-purpose machines, kinds of goods and processing content thereof that its independent fixing preparation processing is respectively arranged, therefore must have a large amount of special purpose machinerys in case with various kinds of goods broken be filtered into different granular sizes.In other words, these special purpose machinerys all are such, and promptly for example the breaking capacity of each disintegrating machine is fixed, and the screen area of each vibrating screener is also fixed.On the other hand, the kinds of goods of preparing processing differ greatly on the performance according to its kind, thereby they not only according to the size of its bulk material, shape, proportion, granularity, water content with because the performance aspect freezing cohesion or the like is different, and the kinds of goods of same kind still can be variant on performance owing to the environmental condition (weather, humidity etc.) in their storage places.Come from the example of vibrating screener, for example, if screen area is fixed, so just there is conflicting requirement, promptly in order to improve the quality of screening, the time that needs the kinds of goods of processing to be trapped on the screen surface just needs lengthening, but for the efficient that will improve screening operation then time of being trapped on the screen surface of kinds of goods just need to shorten, thereby just must process the character of kinds of goods as required and the environmental condition in place is found out an optimum condition as the trade-off points of these requirements.

In addition, the conventional disintegrating machine and the shortcoming of vibrating screener are that the discharge position of preparing to process the charging position of kinds of goods and process product must define a fixing position relation, but are not that position between the status that processes product on the stacking place of raw material and the building site is closed and fastened the operating position that total energy guarantees to have a best.

The present invention is because the generation of this situation, its main purpose is to provide a kind of multifunctional mobile plant equipment of using for multiple series products, it can be in the production of kinds of goods, stack place or consumption place gives effectively broken or screening according to the needs of occasion to the kinds of goods of preparing processing, and the position that can also have retractility ground to solve on the spot between the stowed location of preparing the processing kinds of goods and the discharge position that has processed product concerns.

Another object of the present invention provides a kind of such movable type mechanical device, and it can adjust condition of work according to size, hardness and the characteristic of preparing the processing kinds of goods with changing, thereby with the operating efficiency fragmentation of the best or screen this kinds of goods.

Another object of the present invention provides a kind of such mobile plant, its design makes it excessive vibration can not take place on a car limit structure, and this car limit structure the time is used as the bearing support of a Work machine of being made up of a disintegrating machine or screening machine in operation.

Further object of the present invention provides a kind of such mobile plant, its design can be used a vehicle chassis structure in such a way jointly, promptly to the replacing between kind or variety classes Work machine, can not consider from the difference of the useful life between Work machine of forming by a disintegrating machine or screening machine and the job category that need finish of the viewpoint of maintenance, also have, the maintenance of Work machine and vehicle chassis can each be carried out in a suitable maintenance workshop by this way, can also operate if promptly have one in Work machine and the vehicle chassis, it just can continue to be used and needn't stop work.

According to the present invention, each purpose recited above can be reached by following mobile plant.

That is to say that the mobile plant of basic purpose comprises a hopper that is installed on the vehicle chassis front portion that can travel according to the present invention, hopper has an open top to be used to admit the kinds of goods and the outlet towards the vehicle chassis rear side of preparing processing; Be used for being transmitted in the charging gear of the preparation processing kinds of goods in the hopper by outlet; Be contained in the cross-over connection conveying device at vehicle chassis middle part, it has one towards its rear portion acclivity, so that will be transported towards the rear portion on chassis from the kinds of goods that the hopper outlet sends by charging gear; A Work machine that is contained in the vehicle frame rear portion in order to admit the kinds of goods that fall from cross-over connection conveying device rear end to carry out desired essence process operation, for example carries out fragmentation or screening to the kinds of goods of preparing processing; In order to will be sent to the outlet conveying device outside the vehicle chassis by the kinds of goods that Work machine processes; And in order to adjust the speed control unit of the speed of charging gear and cross-over connection conveying device respectively with changing.

In this mobile machine equipment according to the present invention one better aspect, speed control unit comprises that a speed that is used to control the outlet conveying device makes the proportional controller of speed of itself and cross-over connection conveying device.

Also have, in this mobile plant according to the present invention another more excellent aspect, vehicle chassis is to be made of a semitrailer that tractor drew, be fore-end and rear end part basically on vehicle chassis first limit with and at least one mid portion on all be provided with jack device, so that during operation on the ground with the weight supporting of vehicle, jack device at fore-end can withdraw or remove, thereby unlikelyly when tractor is coupled makes obstruction.

Being loaded on the semitrailer is Work machine, and disintegrating machine or as the vibrating screener of vibration source for example has generation and propagates by long and heavier chassis and cause and do not expect that the danger of the vibration of judder takes place at the position when operation.In addition, in the example of common semitrailer, connected by a universal coupling between preceding gooseneck part and the tractor, any fixing outstanding structure can not be contained on the lower surface of gooseneck part, in order to avoid cause machinery each other to disturb in motion.

In contrast, according to the present invention, semitrailer is at its many positions, jack device all is equipped with in the position, front and back end and the middle part that are included in its both sides, thereby jack device just is pressed on the ground when broken work is carried out, supporting the load of vehicle, like this, the excessive high vibration that takes place on the whole length on chassis has also just been avoided.Particularly, the jack device on the fore-end can be withdrawn into suitable going-back position.Thereby when semitrailer is coupled to tractor or unlikelyly in motion have any machinery to disturb to tractor, but perhaps they also can be removal be installed with, and the state of withdrawal can have various forms, just, jack hydraulic cylinder can laterally hold in the palm in the both sides at semitrailer gooseneck position, and perhaps jack hydraulic cylinder can stand upright on the gooseneck position.

Also have, in this mobile plant according to the present invention another more excellent aspect, the gate that can adjust the outlet openings of sizes arbitrarily is equipped with in the outlet of hopper.

Also have, in this mobile plant according to the present invention another more excellent aspect, Work machine can install replaceably from the rear portion, chassis.

Also have, in this mobile plant according to the present invention another more excellent aspect, the adjusting device that the angle of inclination is housed on the cross-over connection conveying device is to change the height of cross-over connection conveying device rear end.

Also have, in this mobile plant according to the present invention another more excellent aspect, the outlet conveying device comprises that one is positioned at below the Work machine along the rear portion discharge conveyer of the longitudinal extension of vehicle.

Also have, in this mobile plant according to the present invention another more excellent aspect, a disintegrating machine is housed as Work machine.As disintegrating machine, can select a for example jaw crusher according to predetermined purposes, or single roller or double-roll crusher.

Also have, in this mobile plant according to the present invention another more excellent aspect, a vibrating screener is housed as Work machine.In this example, vibrating screener comprises one first outlet, be used for to stay the bigger kinds of goods anterior discharge of particle diameter on the screen cloth towards the chassis, with one second outlet, be used for and discharge below vibrating screener by the smaller kinds of goods of the particle diameter that screen cloth falls downwards, therefore export the discharge ribbon conveyer that conveying device comprises a width, be used on the position of vibrating screener front, kinds of goods being discharged from the direction of first outlet with chassis width, with a rear portion discharge ribbon conveyer below vibrating screener, be used for kinds of goods being sent to the rear portion on chassis from second outlet along the longitudinal extension of vehicle.In addition, vibrating screener can comprise a plurality of screen clothes that overlap each other, and therefore needs configuration to be equivalent to a plurality of first outlets of screen cloth number, and correspondingly settles a plurality of width discharge ribbon conveyers that are arranged side by side again.As long as the driving direction of its conveyer belt of conversion, each width discharge ribbon conveyer just can be sent to kinds of goods arbitrary limit on the left side, chassis and the right.

Rear portion at vehicle chassis, when vibrating screener is accepted the kinds of goods that fall from the cross-over connection conveying device in the position, rear end in the above, and make kinds of goods on the screen cloth of top rake, in current downflow, vibrate and screen to kinds of goods towards the place ahead, the number of times of the angle of screen openings and inclination and screen cloth vibration can be adjusted, so that guarantee desired screening usefulness according to the character of the kinds of goods of preparing processing.The vibration of vibrating screener screen cloth is to be rotatablely moved by the off-centre around the axle on the vehicle chassis width to produce, and the direction of eccentric rotation is reversible.In other words, if after the off-centre rotation with the easy flow direction that flows downward with respect to kinds of goods on screen cloth is coupled with, kinds of goods on the screen cloth just can be to flow downward than higher speed, yet when one with respect to kinds of goods flow direction on screen cloth after rightabout eccentric rotation is coupled with, kinds of goods on the screen cloth just flow downward with lower speed, so just can conversion the efficient of screening.Thereby, as long as a variable vibration number adjustment is combined with previous adjustment, just might adjust screening effeciency very naturally in more perfect mode.Like this, on this vibrating screener.Screen openings, in the direction of rotation of angle of inclination, vibration number and vibration each can be according to the character and the change of operating environment condition of preparing the processing kinds of goods at least, so that when operating, can utilize the whole surface of vibrating screener screen cloth, and the kinds of goods of preparing processing are to be provided by the dose rate that passes through that speed change dispenser and speed change conveyer are adjusted corresponding to vibrating screener, thereby make process operation not have any delay.Consequently at any time can both select best screening rate and efficient.

Also have, vibrating screener is gone up and preferably can adorn the charging plate that lastblock is used to accept the kinds of goods that fall and supply from the cross-over connection conveying device in its back-end, and between charging plate and screen cloth and/or on screen cloth from upper process, a baffle plate that extends at width is set.The purpose that charging plate and baffle plate are set is that the kinds of goods that fall can be flowed downward on the screen cloth face with extensively distributing, thereby the whole surface of vibrating screener screen cloth can both effectively be used, and has therefore improved the efficient of screening and the throughput of screening.

In addition, the vibration that cause owing to the vibrating screener actuating at interval between cross-over connection conveying device rear end and charging plate becomes flexible this indefinite situation and preferably can be used by this way, promptly a plurality of shovel spares of giving prominence to towards charging plate in its lower section can be installed on the position, termination of cross-over connection conveying device, thereby the kinds of goods of relatively large shape are when flowing to the screen cloth face downwards, on charging plate, be subjected to fragmentation earlier, even if therefore since for example make moist or freezing form block kinds of goods also can be in addition broken by the shovel part, thereby the kinds of goods that prevented bulk flow on the screen cloth face.Also have, can not be if having by huge possibility that falls from the cross-over connection conveying device of shovel part fragmentation, fence with appropriate intervals of attaching on the rear end of cross-over connection conveying device then just can make on the huge place of directly dropping on car soot outward and so on.

Because its all critical pieces of mobile plant of the present invention all are contained on the vehicle chassis that can travel, so it just can be moved toward the place that needs kinds of goods broken or that screening is processed to bank up and processes on the spot.For example, that coal, coke, iron close is many, the material of cast iron dreg and so on all is that ground on the scene piles Yi Gaoduo, and various building waste and food and beverage waste product also often are deposited in indivedual given places.Because can being moved toward a side or the heap center of this kinds of goods heap on the place, mobile plant of the present invention carries out processing work, and charging gear and cross-over connection conveying device all can be adjusted to various speed, therefore just might be by changing its processing conditions, for example broken or speed of screening and efficient make Work machine to every kind of different grain size distribute, the various kinds of goods of density etc. carry out the processing of optimum efficiency.

On mobile plant of the present invention, the kinds of goods of preparing processing are by bucket crane, similar tool such as hydraulic power shovel are packed in the hopper of front portion, chassis, so kinds of goods are discharged on the cross-over connection conveyer with constant speed by the gate that is adjusted to suitable A/F from the dispenser in hopper exit.In this example, be preferably in the hopper outlet and some nozzles are being set between the appropriate location on the cross-over connection conveyer, be used to the humidity control spray water of improving the operating efficiency purpose or prevent the dust spray water thereby from nozzle, spray out.Spray water can spray from front portion, chassis to rear portion in the space between material feeding outlet and the cross-over connection conveying device so that carry out humidity control to fall the kinds of goods on the cross-over connection conveying device and the conveyor belt surface of cross-over connection conveying device from the hopper outlet, also can obtain extra humidity control from top spray being carried at the lip-deep kinds of goods of cross-over connection conveying device by making spray water.

The cross-over connection conveyer is contained in the middle part on chassis backwards in acclivitous mode, and the rear end of cross-over connection conveyer is placed in acclivitous high-order bit.Work machine is contained in the rear portion on chassis below cross-over connection conveyer rear end, for use in accepting and kinds of goods broken or that screening falls from the cross-over connection conveyer.Be arranged in the hopper on the chassis, cross-over connection conveyer and Work machine can be effectively be decreased to the minimum numerical value that requires with the size of height of car and vehicle length, can make the whole dimension of vehicle meet the relevant legal limit of vehicle defined that travels on highway of vehicle method by this way and measure.

In mobile plant of the present invention, hopper and Work machine are contained in the front and rear on chassis respectively, both are arranged to skewed cross-over connection conveyer by one and are connected, and make the kinds of goods of being discharged with the flow rate of adjusting by dispenser from the hopper outlet send Work machine to desired schedule speed by the cross-over connection conveyer.Particularly, in mobile plant of the present invention, dispenser and cross-over connection conveyer all belong to speed changing type, can control its speed by speed control unit, in addition, also be provided with a gate in addition so that regulate the size of its opening in the hopper exit, like this, if for example drive the cross-over connection conveyer at a relatively high speed, the kinds of goods of a certain size of being discharged by gate from hopper with constant rate of speed by dispenser just can be sent to the Work machine with lower time per unit flow rate so, yet the speed drive that the cross-over connection conveyer also can be lower, the kinds of goods of being discharged from hopper with constant rate of speed by dispenser just are sent to the Work machine with the higher flow rate of time per unit.In addition, aspect Work machine, for example, in the example of disintegrating machine, broken performance can be through changing the disintegrating machine blade, the broken opening of roller or its speed and changed, and in the example of vibrating screener, the performance of screening can be through changing the screen cloth mesh size or change the number of times of vibration and rotation direction and being changed, consequently may be corresponding to the mechanical strength of Work machine and working ability and according to the various character of for example preparing processing kinds of goods and the desired product of wanting, for example, proportion, hardness, product particle size of wanting and moisture content and stipulate and carry out best condition of work selectively, its mode is if the granular size that proportion and hope are wanted is that height or hardness are low kinds of goods, then send into to big quantity to operate effectively, and the granular size that proportion and hope are wanted is kinds of goods low or that hardness is high, then sends into lower flow rate, to avoid that Work machine is caused any excess load.

Above-mentioned Work machine, for example can improve a little with the Work machine of ordinary fixed pattern can vehicle-mounted Work machine to become one for disintegrating machine or vibrating screener, in mobile plant of the present invention, Work machine can be installed from rear portion, chassis interchangeable ground, thereby chassis and Work machine can be exchanged mutually, so that the maintenance on Work machine or chassis, according to the required operation of carrying out, the Work machine on the chassis also can be changed into a different types of Work machine.Like this, one of intact chassis and Work machine just can continue operation and can not leave unused, and their maintenance work can be carried out in each comfortable its special-purpose repair shop.

If adorn a jaw crusher as disintegrating machine, this machine goes for goods material miscellaneous, for example from the goods material of the middle hardness of coal and coke to hard especially goods material as titanium ore, and this machine also is particularly suitable for the goods material to be broken into the sort of purposes of single-size size.

Also have, if adorn a mono-roller type disintegrating machine as disintegrating machine, this machine is suitable for broken soft or medium soft raw material, and this machine can become particle of uniform size with these material fragmentations and only contain a spot of fines end.

In addition, if adorn a double-roll crusher as disintegrating machine, this machine is suitable for broken soft or medium soft raw material most, and broken hard raw material for the second time and for the third time, and this machine also is suitable for the goods material is broken into uniform fine granularity powder.

According to mobile plant of the present invention, it can be moved into the place of preparing the accumulation of processing kinds of goods and operate, thereby the transhipment step of preparing the processing kinds of goods just can have been done without, in addition, be arranged on cross-over connection conveyer between hopper and the work mechanism at an easy rate with unwanted exogenous impurity, as hard goods, wood chip and so on is removed by magnetic separtor in case of necessity, perhaps by standing in staff before the Work machine with manually removing, also the mobile plant that has the semitrailer of requirement can be left for a place that does not have working equipment, be loaded with variety classes Work machine on the semitrailer corresponding to local action, constitute one group of Work machine of arranging preferably, also can only there be the place of part working equipment to constitute one group of comprehensive Work machine, remedies the deficiency of one or more functions with this mobile plant at one.In addition, because mobile plant is a movable-type, therefore it must deal with the kinds of goods of various preparation processing, according to the present invention, dispenser and cross-over connection conveyer are for example to be made up of the speed change pattern, therefore can operate with the condition of work of the best corresponding to the character of preparing the processing kinds of goods.
