The both sides of the machine core of the utility model are provided with rolling wheels which are arranged on the rail in the machine core, and the inner part of the machine core is provided with an electronic weighing device which comprises a load detection device and a speed detector. The utility model realizes the dynamic weighing of the coal-feeding rubber belt conveyer and has the advantages of simple structure and convenient installation and maintenance.
Description
The utility model relates to a kind of boiler coal feeding equipment of thermal electric generation station-service, particularly a kind of later-model metering-type adhesive tape feeder.
The general employing of existing heat power plant boiler coal supply equipment buried scraper plate feeder or adhesive tape feeder, this class coal supply equipment can only be realized mono-coal supply function, and can not in the process of coal supply, carry out Dynamic Weighting to coal, and calculate automatically and show instantaneous coal supply rate and accumulative total coal-supplying amount.Though and existing belted electronic balance has the dynamic measurement function, its scantling of structure is bigger, can only be used for relatively large travelling apron, and can not be used for the less feeder of volume.
The parts of the mass transport part of existing adhesive tape feeder directly are assembled on the housing, and make the maintenance of feeder and safeguard extremely inconvenience, and the complex structure of housing, poor sealing is made difficulty.
The purpose of this utility model is to provide a kind of later-model metering-type adhesive tape feeder, and it can carry out Dynamic Weighting to coal in the process of coal supply, and this utility model is simple in structure, and is easy to maintenance.
The purpose of this utility model is achieved in that it comprises that housing, movement and main drive thereof, device for transporting objects and electronic weighing device are assembled in both sides and have on the framework of roller, forms movement of the present utility model.Enclosure interior has two tracks, and the roller of movement is walked in orbit.Electronic weighing device detects two parts by loading detection and speed to be formed, and it is a metering of installing carrying roller under the mass transport belt that loading detects, and metering carrying roller and LOAD CELLS link, and what the speed detection was adopted is pulse detector.When transferring adhesive tape with coal when the coal inlet of feeder is transported to coal outlet, be installed in electronic weighing device under the belt and promptly detect weight meter and measure the weight of material, and can show instantaneous flow and cumulative amount by instrument by loading and speed.
Can directly link between metering carrying roller and the LOAD CELLS, also can link by a lever.
The transmission of the utility model power realizes by main drive.This device is made up of bearing, main driving axle, bearing seat and plum blossom coupler.Main drive is installed on the flange seat of housing.Unclamp hold-down bolt, move axially main drive, movement and driving device are thrown off, so movement just can be extracted out in housing.For serviceability of the present utility model is further improved, the utility model adopts the annular jointless rubber conveyer belt that has corrugated sidewall.For improving drive ability of the present utility model, be provided with the coal seam regulating control in the entrance of feeder.Control apparatus and coal seam baffle plate that this coal seam regulating control is made up of support, leading screw and handwheel are formed.
Movement of the present utility model can be walked on the track in casing, and can extract out in housing, thus the maintenance of equipment, install extremely convenient.Electronic weighing device relatively simple for structure, volume ratio primary electron belt claims to dwindle, and therefore can be installed in the movement, makes the structure of equipment obtain simplifying.The annular jointless rubber conveyer belt that has corrugated sidewall can prevent that not only coal from coming off from adhesive tape, and the non junction structure can improve the measuring accuracy of feeder.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.
Fig. 1 is the general illustration of a kind of instantiation of the utility model.
Fig. 2 is a cut-away view.
Fig. 3 is the cassette mechanism structure scheme drawing.
Fig. 4 and Fig. 5 are the loading detection architecture scheme drawings of electronic weighing device.
Fig. 6 is the main drive scheme drawing.
Fig. 7 is a coal seam controller structure scheme drawing.
With reference to Fig. 1-7, the concrete structure of present embodiment is elaborated.
Present embodiment has housing 1, main drive 2, and distribution terminal case 3, coal seam regulating control 4, coal gate 5 and access door 6 are housed on the housing 1.Housing 1 internal fixation is equipped with two tracks 9, and framework 13 both sides have roller 14, and movement 8 promptly is placed on the track 9 by roller 14, can be along track 9 walkings.Movement also comprises drive roll 12, passive cylinder 17, loading detecting device 15, speed detector 16 and transferring adhesive tape 11.After material entered feeder from coal inlet, drive roll 12 drove adhesive tapes 11 motions, and coal is transported to coal outlet from the coal inlet of feeder.In the process of carrying coal, be installed in adhesive tape 11 following re-detection devices 15 and can detect the load per unit that produces coal, speed detector 16 detects the speed of adhesive tape simultaneously.The microcomputer system of feeder is handled the instantaneous coal supply rate and the accumulative total coal-supplying amount that just can draw feeder with computing with above-mentioned signal, realizes the metering of feeder.
Have two parallel tracks 9 in the housing 1 of feeder, and the movement 8 of feeder just is installed in face on the track 9.Roller 14 is equipped with in both sides at the framework 13 of movement 8, so movement 8 can be walked freely on track 9.Therefore open the access door 6 of feeder end and just can at an easy rate movement 8 be extracted out from housing 1, overhaul and safeguard very convenient.
The loading of electronic weighing device detects and can adopt as Fig. 4 or structure shown in Figure 5, below transferring adhesive tape 11, establish a metering carrying roller 29, metering carrying roller 29 can directly link with two end axles and LOAD CELLS 26, also can link by hung lever construction and the LOAD CELLS 26 that sheet 31, microscope carrier 30, plate 27 constitute by support.28 is roller rack among the figure, links with microscope carrier 30.
The main drive 21 of feeder is fixed on by fitting-up bolt 20 on the flange seat 19 of housing 1 of feeder, and it connects with drive roll 12 mutually by coupler 18, in order to transferring power.Coupler 18 is selected for use has buffer action and to the less demanding plum blossom coupler of setting accuracy.Unclamp binder bolt 20, move axially main drive 21, then coupler 18 separated into two parts, main drive 21 and drive roll 12 disengagements.Thereby movement 8 just can break away from system and extract out from housing.Main drive 21 makes the effect of drive roll 12 off-loads in addition simultaneously, makes the axle of drive roll 12 not be subjected to radial weight.
For making the coal stream on the transferring adhesive tape stable, the scope of exerting oneself of feeder is strengthened, at the coal inlet place of feeder coal seam regulating control 4 is housed.Control apparatus and coal seam baffle plate 25 that coal seam regulating control 4 is made up of handwheel 22, support 23 and leading screw 24 are formed.Rotation hand wheel 22, just can drive coal seam baffle plate 25 by leading screw 24 moves up and down, thereby adjusting coal seam thickness, improve the drive ability of feeder, and the bottom of coal seam thickness baffle plate 25 has arc notch, this structure can make the operation on adhesive tape of coal stream more stable, reduces the resistance at baffle plate place simultaneously.
The utility model feeder can be used for metering and carries other bulk material.
