Description
Technical Field
The invention relates to the technical field of crushing, in particular to a high-efficiency shearing type crusher. The high-efficiency shearing type crusher is used for crushing a solid or brittle solid with certain cohesiveness into a solid with a certain particle size, such as a cohesiveness mud cake with a water content of 45-85%, a filter cake of a chemical product with certain viscosity, and the like.
Background
At present, the crushers for the brittle solids are diversified, and the crushers make great contribution to the technical progress of industrial and agricultural production. Although the variety is wide, the present pulverizers can be classified into three types in principle, an extrusion type pulverizer, a hammer type pulverizer, a high-speed impact type pulverizer in which solid particles are carried by a fluid, or an impact type pulverizer in which solid particles are thrown out at a high speed by centrifugal force. However, it is not suitable to use these three types of pulverizers for solid blocks having a certain viscosity, such as mud cakes having a water content of 45% to 85%, or blocks of chemical products having a certain viscosity. With the three types of mills, most of the agglomerates of the sticky species are squeezed or impacted into thinner cakes which, when stacked, stick together into chunks.
The present invention addresses such deficiencies. Meanwhile, the invention can also be used for crushing the brittle materials, and when the invention is used for crushing the brittle materials, the mutual extrusion and friction (further release after the specification) of most crushed materials are avoided, and the energy-saving effect can be achieved.
Disclosure of Invention
In order to solve the technical problems, the invention provides the efficient shearing type grinder which is energy-saving and environment-friendly, improves the production efficiency of a single machine, reduces the pollution of dust to the environment and can limit the maximum grinding particle size.
The invention provides a high-efficiency shearing type crusher, which comprises a feeding hopper and an upper machine shell, and is characterized by also comprising:
the low-speed crushing cutter shaft is provided with a plurality of low-speed crushing cutter wheels, and the low-speed crushing cutter wheels are provided with low-speed rotary crushing cutters;
the crushing device comprises a high-speed crushing cutter shaft, wherein a plurality of high-speed crushing cutter wheels are arranged on the high-speed crushing cutter shaft, each high-speed crushing cutter wheel is provided with a high-speed rotating crushing cutter, a gap with the same width is arranged between every two adjacent high-speed rotating crushing cutters in the axial direction, and the width of each gap is larger than that of each low-speed rotating crushing cutter;
the low-speed crushing cutter shaft and the high-speed crushing cutter shaft are arranged adjacently in parallel, the rotating directions of the low-speed crushing cutter shaft and the high-speed crushing cutter shaft are opposite, the low-speed rotary crushing cutter shaft and the high-speed rotary crushing cutter shaft are arranged in an axially staggered mode, and the low-speed rotary crushing cutter shaft is inserted into a gap between the high-speed rotary crushing cutter shaft and does not interfere with each other during rotation.
In the above scheme, when the low-speed rotary crushing cutter and the high-speed rotary crushing cutter are used for cohesive solid blocks, the cross section of the blade is rectangular, the cross section of the blade is parallel to the axes of the low-speed crushing cutter shaft and the high-speed crushing cutter shaft, and 90 corners of the rectangle keep sharp angles. When the crushing cutter is used for crushing fragile solid blocks, the cross section of the cutter blade is rectangular as before, and the 90 corners of the rectangle should be made into circular arcs.
The difference in the number of revolutions of the two forms a relative movement. Thereby forming a shearing action on the cohesive solid matter. The small blocks of the adhesive solid after being cut fall to the lower shell and the discharge opening in the discharge opening along with the high-speed rotating crushing cutter and the low-speed rotating crushing cutter to be discharged because larger neutral positions are arranged in the circumferential direction and the axial direction of the high-speed rotating crushing cutter and the low-speed rotating crushing cutter. The plurality of fast crushing knives and the slow crushing knives on the two shafts are used as blanking conveyors even though the shearing knives are used as the star-shaped blanking devices. If the conveying belt is arranged below the lower shell and the lower opening in the lower opening, the cohesive solid shearing machine can also uniformly distribute small sticky materials on the belt, and the small sticky material blocks can be prevented from being bonded again to form large material blocks after being dried on the belt for a period of time.
In the above scheme, the pinion and the gearwheel are used for generating the difference of the rotation numbers of the two shafts of the low-speed crushing cutter shaft 7 and the high-speed crushing cutter shaft, the pinion and the gearwheel function or are replaced by a sprocket, but the sprocket needs to be added with an intermediate idler wheel to ensure the rotation directions of the two shafts.
It is obvious that the shearing type pulverizer can also be used for pulverizing brittle substances such as ores and the like. When the crushing cutter is used for crushing brittle substances, the axial distance between the high-speed crushing cutter and the low-speed crushing cutter is adjusted, so that the maximum discharge particle size can be limited. For crushing brittle solids, the crushing blade with a rectangular cross section is required to be oval, and the bending moment force is required to be applied to a larger solid block. At least three knives are in contact with the larger solid block, i.e. at least three points of action. Wherein, a cavity is arranged between two acting points at the lower part of the solid block, the solid block is equivalent to be acted in the middle under the action of a crushing knife in the middle of a simply supported beam, and the solid block is extruded by bending moment force under three acting forces and is easy to crush. When larger solid pieces are crushed, the crushed small pieces fall down from the axial neutral position between the next two crushing knives. Meanwhile, another part of small fragments crushed on the slow blade also moves upwards to an axial neutral position between the two crushing blades, because of no constraint of a metal wall surface, the fragments are subjected to small force to generate dispersion movement and leave the crushing blades, and certainly, the solid blocks which do not fall downwards are continuously crushed by three forces. The small solid crushing blocks leave the crushing knife under small acting force, and the useless work consumed by mutual extrusion and friction between the crushed small blocks between the double-roller crusher or the elliptical crusher is avoided, so that the shearing type crusher can save energy, namely, the energy consumed by crushing the materials with the same unit mass is reduced.
In the above scheme, the high-speed rotating crushing cutter and the low-speed rotating crushing cutter of the high-efficiency shearing type crusher are driven by the low-speed crushing cutter shaft and the high-speed crushing cutter shaft to rotate relatively. The high-speed rotating crushing cutters are fixedly connected with the high-speed crushing cutter wheel. And the high-speed crushing cutter wheels are uniformly distributed and installed on the high-speed crushing cutter shaft along the axial direction. The high-speed crushing cutter shaft is arranged on the bearing at the fixed end of the high-speed crushing cutter shaft and the bearing at the free end of the high-speed crushing cutter shaft. The free end bearing of the high-speed crushing cutter is arranged in the bearing box. And the free end bearing of the high-speed crushing cutter shaft is arranged in the bearing box. The plurality of low-speed rotary crushing cutters are fixedly connected with the low-speed crushing cutter wheel. And the plurality of low-speed crushing cutter wheels are uniformly distributed and installed on the low-speed crushing cutter shaft along the axial direction. The low-speed crushing cutter shaft is arranged on the bearing at the fixed end of the low-speed crushing cutter shaft and the bearing at the free end of the low-speed crushing cutter shaft. And the fixed end of the low-speed crushing cutter shaft is mounted in the bearing box through a bearing. And the free end bearing of the low-speed crushing cutter shaft is arranged in the bearing box. In the low-speed rotary crushing cutter, a plurality of sawtooth-shaped grooves are arranged on the surface of the low-speed rotary crushing cutter opposite to the carrying support force so as to prevent the sliding in the crushing process. And a plurality of sawtooth-shaped grooves are also formed on the stress surface of the high-speed rotating crushing knife. The rotation of the low-speed crushing cutter shaft is driven by the motor and the reducer to rotate through the connected coupler. The large gear is fixedly installed on the low-speed crushing cutter shaft and is driven by the low-speed crushing cutter shaft to rotate. The rotation of the small gear is driven by the big gear. The pinion is fixedly arranged on the high-speed crushing cutter shaft. The axes of the low-speed crushing cutter shaft and the high-speed crushing cutter shaft are arranged in parallel.
In order to avoid that small pieces of materials which are crushed in the circumferential direction neutral position and the axial direction neutral position between the low-speed rotating crushing cutters are brought back to the feeding hopper due to bridging, a plurality of scraping plates are fixedly arranged on the wall surfaces of the lower machine shell and the feeding hole in corresponding matching positions respectively. And similarly, in order to avoid that the crushed materials in the circumferential neutral position and the axial neutral position of the high-speed rotating crushing cutter are brought back to the feeding hopper due to the bridge, a plurality of scraping plates are fixedly arranged on the wall surfaces of the lower machine shell and the feeding hole at corresponding matched positions respectively.
In the above scheme, the feeding hopper, the upper machine shell, the lower machine shell and the feed opening are split along a plane formed by the axes of the low-speed crushing cutter shaft and the high-speed crushing cutter shaft, and the feeding hopper, the upper machine shell, the lower machine shell and the feed opening are fixedly connected by bolts.
In the scheme, a fixed revolution difference is formed by meshing a pinion on the high-speed crushing cutter shaft, namely the left blade shaft, and a bull gear on the low-speed crushing cutter shaft, namely the right blade shaft, so that shearing force is generated on mud cakes by the left high-speed rotary crushing cutter and the right low-speed rotary crushing cutter under the revolution difference to achieve the purpose of crushing the mud cakes.
The invention designs a shearing type crusher by utilizing the shearing principle. The principle is that the right-angle edge of a rectangular blade moves relatively to shear a sticky solid block. Changing the extrusion and impact crushing principle into the shearing principle in principle needs to solve the design principle of relative movement of scissors and the basic principle of how to improve the crushing yield in unit time.
Is the action of cutting continuous or reciprocating? Obviously, the reciprocating shearing can cause more and complex moving parts, and repeated acceleration and deceleration movement is generated, so that the energy consumption and the noise are increased. It can also be a short life of the device. The invention designs the relative movement of the shearing blades into the relative rotation of the two rows of shearing blades. When the left blade and the right blade are nested, it is obvious that the left blade and the right blade rotate in the same direction, i.e. the left blade moves downwards, the right blade moves upwards, and the left blade and the right blade move relatively. Obviously, the purpose of shearing the viscous mud cakes is achieved, but the sheared mud cakes can not fall smoothly. The left blade moves downwards to drive a part of mud blocks to move downwards, and the right blade moves upwards to drive most of mud blocks to move upwards and enter the feeding hopper. The friction of the already shear-comminuted clods and the not shear-comminuted cakes against one another produces an ineffective energy consumption. According to the principle of dynamics, when the Reynolds number (and the friction loss with air) reaches a large value under a certain speed condition, the power consumption of the friction force is proportional to the square of the relative speed. The left blade is filled with mud blocks in the axial direction and the circumferential direction, and when the rotating direction moves upwards, the mud blocks which are not crushed are difficult to fall (or be pressed) to the sheared areas, so that the shearing crushing cannot be normally carried out. To ensure that the clod is separated downward from the axial and circumferential spaces of the left and right blades, downward movement can only occur in the region where the left and right blades are nested. If the left blade and the right blade move downwards at the same time, no supporting force or shearing force of the downward pressure exists. In order to ensure that the support reaction force and the shearing force are generated, and simultaneously ensure that the sheared mud blocks are smoothly separated from the shearing area, the waste of energy caused by mutual friction of the sheared mud blocks and the uncut mud blocks is avoided. The invention designs that the rotating directions of the left blade and the right blade are opposite, the rotating direction of the left blade is omega 1, and the rotating direction of the right blade is omega 2. I.e. downward at the same time where both are nested. However, the left blade ω 1 rotates more than the right blade ω 2, and the two blades can move relative to each other. The design principle solves the problem that the back reaction force and the shearing force can be generated, and simultaneously, the sheared mud blocks can fall smoothly. The support reaction force of the right blade is formed by two blades. The crushed cake corresponds to a state of a simply supported beam. The lower pressure of the left blade is in the middle of the simply supported beam. In the stressed state, no matter how fast the left blade and the right blade are relative to each other, the mud cake can be easily cut off as long as relative movement exists. The ineffective displacement of the acting force in the shearing process is eliminated, and the ineffective displacement of the acting force is the useless work. The energy-saving effect is achieved. Meanwhile, the crushing yield of the sheared mud blocks in unit time can be determined by adjusting the revolution of the right blade. The function of cutting the mud cakes with fixed weight can be realized by adjusting the revolution of the right blade within a certain precision range. And a foundation can be laid for uniform distribution. The function of the revolution difference is realized in such a way that a fixed revolution difference is formed by meshing a pinion on a high-speed blade shaft, namely a left blade shaft, and a bull gear on a low-speed blade, namely a right blade shaft, so that the left blade and the right blade generate shearing force on mud cakes under the revolution difference to achieve the purpose of crushing the mud cakes. This kind of design can also improve high-efficient shearing type rubbing crusher's energy utilization simultaneously. The energy-saving effect is achieved.
To increase the throughput per unit time. The design principle of the invention is that tens to hundreds of blade wheels are additionally arranged on the rotating shafts of the left blade and the right blade, and the mud cake crushing weight per unit time can be achieved at low revolution.
Compared with the related art, the shearing type pulverizer provided by the invention has the following beneficial effects:
1. the energy-saving effect of the pulverizer is improved.
Because the solid block is crushed by the bending moment force, the crushed small solid block can not be continuously subjected to larger extrusion force and friction force due to the limitation of the metal wall surface. The clay cake sticky mass is subjected to a shearing force, so that the deformation of partial clay cake is eliminated, and the clay cake sticky mass is easily crushed. Both the mud cake and the brittle mass can be crushed at low rotational speeds. Therefore, the high-efficiency shearing type crusher has the energy-saving effect.
2. The production capacity of single machine is improved.
The number of the low-speed crushing cutter wheel 22 and the high-speed crushing cutter wheel 23 and the number of the matched crushing cutters are increased, so that the output of a single machine can be improved under the condition that the rotation number of the low-speed crushing cutter shaft 7 and the high-speed crushing cutter shaft 9 is not increased.
3. Reduce the pollution of dust to the environment
Because the number of rotations of the low-speed pulverizing cutter shaft 7 and the high-speed pulverizing cutter shaft 9 is low. When the brittle solid is crushed, more dust is not generated. The pollution of dust to the environment is reduced.
4. Limiting maximum crushed particle size
The axial distance between the low-speed rotating crushing knife 2 and the high-speed rotating crushing knife 3 is adjusted correspondingly, so that the crushing grain size of the solid material can be defined more uniformly. .

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Specific implementations of the present invention are described in detail below with reference to specific embodiments.
Referring to fig. 1 to 2, the high efficiency shearing type pulverizer is implemented by placing the viscous solid block 21 into the feeding hopper and the feeding hopper of the upper body 1, and the viscous solid block 21 falls into the neutral positions of the low-speed rotating pulverizing blade 2 and the high-speed rotating pulverizing blade 3 in the circumferential direction and the axial direction by gravity (or applied pressure). The rotational directions of the low-speed crushing blade 2 and the high-speed crushing blade 3 are different from each other, although the rotational directions of the two are known from the rotational arrows in fig. 2, and the low-speed crushing blade 2 and the high-speed crushing blade 3 rotate counterclockwise. The number of revolutions of the high-speed rotating crushing blades 3 is at least 0.5 times greater than the number of revolutions of the low-speed rotating crushing blades 2. Since the axial spaces of the two crushing blades are offset relative to each other, only the shearing crushing force is applied to the viscous solid block 21. When the high-speed rotary crushing blade 3 is relatively moved toward the low-speed rotary crushing blade 2 by the speed difference, the viscous solid mass 21 is cut and crushed by the relatively moving crushing blade. Part of the crushed viscous solid block 21 directly falls to the lower shell and a feed opening of the feed opening 4 under the gravity to be discharged, and if the viscous solid block 21 clamped between two lower blades is pushed out between two axial blades of the low-speed rotary crushing blade 2 by the high-speed rotary crushing blade 3. The pulverized viscous solid block 21 falling on the upper blade surface of the low-speed rotary pulverizing cutter 2 freely falls to the feed opening following the downward rotation of the low-speed rotary pulverizing cutter 2. The viscous solid mass 21 partially adhered between the axial spaces of the blades of the low-speed rotary crushing blades 2 and the high-speed rotary crushing blades 3 is scraped off to the feed opening by the scraper 24. As described above, the viscous solid mass 21 is cut and pulverized, and the rotational speeds of the blades of the low-speed rotating pulverizing blade 2 and the high-speed rotating pulverizing blade 3 are not high, so that the pulverizing efficiency is high.
Obviously, the shearing type pulverizer can also be used for pulverization of brittle substances such as ores and the like. When the crushing cutter is used for crushing brittle solid blocks, the sharp corners of 90 degrees, at which the cross sections of the low-speed rotary crushing cutter 2 and the high-speed rotary crushing cutter 3 are rectangular, are made into circular arcs. When the crushing device is used for crushing fragile substances, the axial distance between the high-speed crushing cutter 3 and the low-speed crushing cutter 2 is adjusted, so that the maximum discharge particle size can be limited. The specific implementation method is that the brittle solid block 21 is added into the feeding hopper and the feeding hopper of the upper machine body 1, and the brittle solid block 21 falls into the neutral positions in the circumferential direction and the axial direction of the low-speed rotating crushing cutter 2 and the high-speed rotating crushing cutter 3 under the action of gravity. Due to the differential rotation of the low-speed rotary crushing blades 2 and the high-speed rotary crushing blades 3, the high-speed rotary crushing blades 3 and the low-speed rotary crushing blades 2 have relative movement. The force experienced by a larger of the brittle solid masses 21 is the bending moment force. The brittle solid mass 21 is crushed under the action of a bending moment. In the configuration shown in fig. 1, the brittle solid mass 21 has at least three knives in contact with the larger brittle solid mass 21, i.e., at least three points of application. A cavity is arranged between two acting points of the two low-speed rotating crushing cutters 2 at the lower part of the brittle solid block 21, the high-speed rotating crushing cutters 3 at the upper part of the middle of the simply supported beam move downwards like a simply supported beam, the brittle solid block 21 is equivalently acted by an acting force at the middle, and the brittle solid block 21 is crushed by the action of a bending moment force due to three acting forces. When the larger mass 21 of brittle solid is crushed, the small fragments after crushing fall through the axial neutral between the next two crushing knives. Meanwhile, the other part of small fragments which are crushed can also move towards the axial neutral position between the two crushing knives, and because no metal wall surface is restrained, the small force applied between the fragments can generate dispersion movement, the fragments leave the crushing knives, and certainly, the solid blocks which do not fall can be continuously crushed by three forces. Because the crushing piece of little solid leaves crushing sword under little effort, avoided like between roller mill or the oval rubbing crusher that kind by the crushing little fragment because receive the restraint of metal wall, make little fragment can't fall in time, can receive great mutual extrusion force and frictional force between the little fragment, produce great useless consumption, so shearing type rubbing crusher can be energy-conserving, is that the energy that consumes in the material of smashing the same unit mass reduces promptly.
The circuits and controls involved in the present invention are prior art and will not be described in detail herein.
