Description

Technical Field

[0001] The invention belongs to the technical field of destruction devices, and in particular relates to a destruction device and a destruction method for waste electric energy metering equipment. Background Art

[0002] With the continuous development of the power industry and the continuous advancement of smart grids, the number of waste electricity metering equipment (such as electricity meters, etc.) is increasing. Some traditional crushing equipment is used to crush and destroy the waste electricity metering equipment. The hydraulic rod drives the lower pressure plate below to crush and destroy the outer shell of the metering equipment, thereby improving the resource recycling rate.

[0003] In the prior art, the outer shell, circuit board, etc. in the metering equipment are disassembled and classified, and then the outer shell part is crushed and destroyed separately. During the crushing and destruction, the outer shell placed on the workbench is crushed by the lower pressure plate, but the crushed outer shell fragments are of different sizes or large fragments. The fragments of different sizes or large fragments will make the subsequent sorting work complicated. In the subsequent processing process, the fragments of different sizes or large fragments need to be additionally processed (such as screening, re-crushing of larger fragments, etc.), which will increase the production process and time. For this reason, we propose a device and a method for destroying waste electricity metering equipment. Summary of the invention

[0018] The present invention also discloses a method for destroying waste electric energy metering equipment, which specifically comprises the following steps:

[0019] S1. Place the plastic shell of the metering device on the mesh-shaped blade in the crushing device, and then start the upper hydraulic rod to drive the upper pressing plate to descend to crush the plastic shell;

[0020] S2, the plastic shell is cut into pieces after passing through the upper mesh blade, and falls on the lower pressure plate below, and then the pieces partially blocked in the upper mesh blade, the blade holder and the lower mesh blade are squeezed and dredged through the anti-blocking piece;

[0021] S3, driving the lower pressure plate to rise by the lower hydraulic rod, driving the broken pieces to rise and pass through the lower mesh blade to cut the broken pieces again;

[0022] S4. The air discharged through the telescopic airbag in the anti-blocking member is blown through the nozzle to clean the broken pieces that have fallen on the net-shaped blade and attached to the bottom of the upper pressing plate.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) The present invention adopts a designed shredding mechanism, which enables the plastic shell to be cut once or twice by the cutting of the upper mesh blade and the lower mesh blade and the pushing of the upper pressure plate and the lower pressure plate, so that the plastic shell can be cut into pieces of appropriate size, which is convenient for shredding into pieces of uniform size, significantly improving the crushing efficiency, and reducing the possibility of subsequent pieces needing to be crushed again. Under the push of the plug column by the telescopic airbag, the pieces stuck in the upper mesh blade, the lower mesh blade and the knife holder are cleared. The knife holder is fixed to the frame by bolts, and the upper mesh blade and the lower mesh blade of different mesh sizes can be replaced according to needs.

[0025] (2) The present invention adopts a designed blowing assembly. After the plastic shell is crushed, the gas in the telescopic airbag is blown through multiple groups of nozzles to the lower surface of the upper pressure plate and the upper surface of the mesh-shaped blade, so as to blow and clean up some attached fragments. The fragments are cleaned up in time to avoid affecting the subsequent cutting and crushing operations, so that the gas in the telescopic airbag is fully utilized.

[0026] (3) The present invention uses a designed limit piece. When the operator is releasing the material, one end of the limit long block is inserted into the limit groove in the connecting block to limit the connecting block, thereby avoiding accidental start-up of the upper hydraulic rod and causing accidental injury to the operator during the process of placing the plastic shell onto the surface of the net-shaped blade, thereby increasing the safety during the operation. When the crushing operation begins, the electromagnet starts to attract the iron block to move, so that one end of the limit long block is separated from the limit groove, which facilitates the operation.

[0027] (4) The blocking member designed in the present invention can move along with the movement of the connecting block when the upper pressing plate starts to press down to crush and cut the plastic shell, thereby blocking the fragments splashing to the outside from the slide grooves on both sides of the frame, thereby preventing the fragments from splashing to the outside and increasing safety.

The two sides of the middle plate 301 are connected to the upper pressure plate 104 below by two sets of fixed springs, which can reset the plug posts 316 and the middle plate 301 through the fixed springs when they are lifted up and reset, so that the plug posts 316 and the middle plate 301 can move upward to their original positions. A plurality of groups of plug posts 316 are fixedly arranged at the bottom of the middle plate 301, and the bottom of the plug posts 316 can pass through the interior of the upper pressure plate 104. Two groups of telescopic air bags 308 are fixedly arranged between the upper plate 302 and the middle plate 301.

[0050] The two sides of the upper pressure plate 104 are fixedly provided with connecting blocks 101, the top of the connecting block 101 is fixedly provided with a vertical plate 307, the upper plate 302 is fixed on the vertical plate 307, the front of the telescopic airbag 308 is fixedly provided with an inlet hose 300, the end of the inlet hose 300 is connected to the external high-pressure blower, and a connecting pipe 310 is fixedly provided between the two groups of L-shaped pipes;

[0051] L-shaped tubes are fixedly provided on the front and back of the upper plate 302, and a pipe joint 313 is fixedly provided at the end of the L-shaped tube. A partition 314 is slidably provided inside the pipe joint 313. The partition 314 is inserted into the pipe joint 313 to close the pipe joint 313, and the partition 314 is opened to open the inside of the pipe joint 313. A lifting sheet 312 is fixedly provided on one side of the partition 314. There is only one set of lifting sheets 312 and one set of long baffles 304 on the front of the device, and there are two sets of lifting sheets 312 and two sets of short baffles 305 on the back of the device.

[0052] Two groups of connecting springs 315 are fixedly arranged between the connecting pipe head 313 and the partition plate 314, and a long resistance plate 304 and two groups of short resistance plates 305 are fixedly arranged on the inner wall of the frame 102. The bottom of the long resistance plate 304 is an inclined structure, which facilitates the lifting plate 312 on the front to contact the long resistance plate 304, and the top of the short resistance plate 305 is an inclined structure, which facilitates the lifting plate 312 on the back to contact the short resistance plate 305, and the end of the lifting plate 312 can contact the surface of the long resistance plate 304 and the short resistance plate 305.

[0053] The present invention adopts a designed shredding mechanism, which enables the plastic shell to be cut once or twice by the cutting of the upper mesh blade 303 and the lower mesh blade 319 and the push of the upper pressure plate 104 and the lower pressure plate 318, so that the plastic shell can be cut into pieces of appropriate sizes, which significantly improves the crushing efficiency and reduces the possibility of subsequent pieces needing to be crushed again. Under the push of the plug 316 by the telescopic airbag 308, the pieces stuck in the net-shaped blade 303, the lower mesh-shaped blade 319 and the knife holder 306 are cleared. The knife holder 306 is fixed to the frame 102 by bolts, and the net-shaped blade 303 and the lower mesh-shaped blade 319 with different mesh sizes can be replaced as needed to facilitate shredding into pieces of uniform size.

[0054] In summary, the cover plate 103 is opened, and then the plastic shell to be crushed is placed on the upper surface of the mesh-shaped blade 303, and then the cover plate 103 is closed to start crushing and cutting, and the two sets of upper hydraulic rods 100 are started to drive the connecting block 101 to descend, thereby driving the upper pressing plate 104 and the upper plate 302 and the middle plate 301 to descend and move, and then the upper pressing plate 104 can contact and press the plastic shell, at this time, the plastic shell part is squeezed and produces larger fragments, and then as the upper pressing plate 104 continues to press down, the plastic shell descends and passes through the mesh-shaped blade 303, and is cut into fragments of suitable sizes by the mesh-shaped blade 303, and then the fragments fall on the surface of the lower pressing plate 318 below;

[0055] When the upper pressure plate 104 descends, it will also drive the lifting pieces 312 at the front and back positions of the telescopic airbag 308 to descend. Before the upper pressure plate 104 descends, the end of the lifting piece 312 located at the front of the telescopic airbag 308 is on the surface of the long resistance plate 304. At this time, the partition plate 314 is in a state of closing the inside of the connecting head 313, and the connecting spring 315 located at the front of the telescopic airbag 308 is in a compressed state, while the lifting piece 312 located at the back of the telescopic airbag 308 is in a state of not contacting the short resistance plate 305. At this time, the partition plate 314 is in a state of opening the inside of the connecting head 313, and the connecting spring 315 at the back of the telescopic airbag 308 is in a compressed state. After the pressure plate 104 is lowered to a certain position, the end of the lifting piece 312 located on the front of the telescopic airbag 308 is away from the surface of the long resistance plate 304, and then the partition plate 314 and the lifting piece 312 are driven to move to the right direction under the reset condition of the connecting spring 315. At this time, the inside of the connecting head 313 is in an open state, and then the gas is quickly filled into the inside of the telescopic airbag 308 on the right through the inlet hose 300 and the connecting head 313, and the telescopic airbag 308 on the left is filled with gas through the connecting pipe 310. At the same time, during the lowering process of the upper pressure plate 104, the end of the lifting piece 312 located on the back of the telescopic airbag 308 contacts the short resistance plate 305, and then The rear lifting piece 312 moves toward the direction close to the pipe head 313, driving the partition 314 to move, and then the partition 314 is stuck in and closes the inside of the pipe head 313, and then the gas filled into the telescopic airbag 308 will not be discharged. At this time, as the height of the inflated telescopic airbag 308 increases, the middle plate 301 below and the multiple groups of plug posts 316 at the bottom of the middle plate 301 are pushed down, and then the bottom of the plug post 316 passes through the upper mesh blade 303, the knife holder 306 and the lower mesh blade 319 in turn to push the blocked fragments downward for dredging, and then the plastic shell can be crushed and chopped into a suitable size, and then according to the above reverse principle , the upper pressure plate 104 rises, and at this time the lifting piece 312 located on the front of the telescopic airbag 308 contacts the long resistance plate 304, driving the partition 314 to move and block the inside of the pipe joint 313, stopping the inlet hose 300 from continuing to inflate the telescopic airbag 308, and the lifting piece 312 located on the back of the telescopic airbag 308 is separated from the long resistance plate 304, thereby driving the partition 314 to move and open the inside of the pipe joint 313, at this time, the gas in the telescopic airbag 308 is discharged outward, and then the middle plate 301 and the plug 316 move upward to reset, and then the plug 316 moves to the original position, and then the subsequent crushing operation can be carried out again, and finally the fragments falling on the lower pressure plate 318 are taken out;

[0056] If some of the fragments are in the shape of vertical strips after being shredded by the mesh blade 303 through the upper pressing plate 104, these vertical strips of fragments will fall on the lower pressing plate 318 below, and the vertical strips of fragments will fall on the lower pressing plate 318 and fall to a horizontal state, and then the lower hydraulic rod 317 is started to drive the lower pressing plate 318 to rise, so that the fragments in the horizontal state on the surface of the lower pressing plate 318 are shredded into a suitable size by the lower mesh blade 319, and then cut After cutting, the lower hydraulic rod 317 drives the lower pressure plate 318 to descend. At this time, most of the fragments fall onto the lower pressure plate 318, while a small part will be stuck in the upper mesh blade 303, the knife holder 306 or the lower mesh blade 319. At this time, the upper pressure plate 104 is pressed down and the plug column 316 cooperates to descend, so that the fragments stuck in the upper mesh blade 303, the knife holder 306 or the lower mesh blade 319 are pushed out and fall onto the lower pressure plate 318, and finally the fragments can be taken out.

[0057] Embodiment 3

[0058] Based on Example 2, please refer to Figure 2 , Figure 3 , Figure 8 , Fig.10 , Fig.11 , Fig.14 and Fig.15 A purge assembly is provided on the back of the telescopic airbag 308, and the purge assembly includes a row pipe 400 fixed on the back of the pipe head 313 and a horizontal pipe 401 slidably provided on the back of the upper pressing plate 104, a telescopic pipe 402 is fixedly provided on the row pipe 400, and a lower pipe 404 is fixedly provided at the bottom of the telescopic pipe 402;

[0059] Two groups of fixing rings 403 are fixedly provided on the back of the upper pressure plate 104, the bottom of the lower tube 404 passes through the interior of the fixing ring 403 and extends to the interior of the cross tube 401, a blocking strip 406 is fixedly provided inside the lower tube 404, and multiple groups of nozzles 405 are evenly distributed at the bottom of the cross tube 401 and along the length direction of the cross tube 401.

[0060] The present invention adopts a designed blowing assembly. After the plastic shell is crushed, the gas in the telescopic airbag 308 is blown through multiple groups of nozzles 405 to the lower surface of the upper pressure plate 104 and the upper surface of the net-shaped blade 303, so as to blow and clean up some attached fragments. The fragments are cleaned up in time to avoid affecting the subsequent cutting and crushing operations, and the gas in the telescopic airbag 308 is fully utilized.

[0061] In summary, when the inside of the connecting pipe head 313 on the back of the telescopic airbag 308 is opened for exhaust, the upper pressure plate 104 starts to move upward, and the exhausted gas passes through the exhaust pipe 400, the telescopic pipe 402, the lower pipe 404, and the transverse pipe 401. The gas in the telescopic pipe 402 contacts the resistance bar 406 during the process of passing through the lower pipe 404. At this time, the impact force of the gas pushes the resistance bar 406 downward, driving the lower pipe 404 and the transverse pipe 401, the nozzle 401, and the nozzle 402 to move upward. 05 moves downward, and then the multiple groups of nozzles 405 descend to the lower surface of the upper pressure plate 104. At this time, the nozzles 405 begin to blow gas to the net-shaped blade 303 and the lower surface of the upper pressure plate 104 to clean the attached fragments. When the gas in the telescopic airbag 308 weakens, the impact on the resistance strip 406 is reduced. At this time, the lower tube 404 rises and drives the cross tube 401 and the multiple groups of nozzles 405 to rise to the original position without affecting the normal use of the upper pressure plate 104.

[0062] Embodiment 4

[0063] Based on Example 3, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 , both sides of the frame 102 are provided with limiting parts for limiting the connecting block 101, and the limiting parts include two sets of circular plates fixed on the two sides of the frame 102, and the internal parts of the circular plates are provided with limiting long blocks 500 and iron blocks 501, and the iron blocks 501 are fixed on the limiting long blocks 500, and the internal parts of the connecting block 101 are provided with limiting grooves for the ends of the limiting long blocks 500 to penetrate, and a mounting spring 503 is fixedly arranged between the top of the limiting long block 500 and the top of the electromagnet 502, and the mounting spring 503 is made of aluminum.

[0064] The present invention uses a designed limiting piece. When the operator is releasing the material, one end of the limiting long block 500 is inserted into the limiting groove in the connecting block 101 to limit the connecting block 101, thereby avoiding the accidental start-up of the upper hydraulic rod 100 and causing accidental injury to the operator during the process of placing the plastic shell onto the surface of the net-shaped blade 303, thereby increasing the safety during the operation. When the crushing operation begins, the electromagnet 502 starts to attract the movement of the iron block 501, so that one end of the limiting long block 500 is separated from the limiting groove, which facilitates the operation.

[0065] In summary, when the plastic shell is placed onto the net-shaped blade 303, the electromagnet 502 is turned off, and the iron block 501 is no longer magnetically attracted to the electromagnet 502. Then, the installation spring 503 compressed above the electromagnet 502 is reset to push the iron block 501 and one end of the limiting long block 500 on the iron block 501 to move toward the direction close to the connecting block 101 and insert into the limiting groove. At this time, the connecting block 101 can be limited, and then the upper hydraulic rod 100 can be limited to avoid accidental start-up of the upper hydraulic rod 100 and accidental injury to the operator. When the crushing operation begins, it can be operated according to the opposite principle mentioned above.

[0066] The top of both sides of the frame 102 are provided with sliding grooves for the connecting block 101 to slide up and down, and the sliding grooves are provided with blocking members, which include vertical baffles 200 fixed to the bottom of the connecting block 101.

[0067] The blocking member designed in the present invention allows the vertical baffles 200 on both sides of the frame 102 to move along with the movement of the connecting block 101 when the upper pressing plate 104 is pressed down to crush and cut the plastic shell, thereby blocking the fragments splashing to the outside from the slide grooves on both sides of the frame 102, preventing the fragments from splashing to the outside and increasing safety.

[0068] In summary, when the connecting block 101 moves downward in the slide groove, the vertical baffle plate 200 will be driven down, thereby driving the two sets of vertical frames 202 on the vertical baffle plate 200 to slide in the L-shaped frame 201. Then, when the upper pressure plate 104 is close to the placed plastic shell, the vertical baffle plate 200 can cover the exposed slide groove in the area below the connecting block 101 to block the subsequent flying debris.

[0069] In this embodiment, cover plates 103 are rotatably provided on the front and back of the frame 102 , an upper hydraulic rod 100 is fixedly provided on the frame 102 , and a working end of the upper hydraulic rod 100 extends to the upper surface of the connecting block 101 .

[0074] S3, the lower hydraulic rod 317 drives the lower pressing plate 318 to rise, driving the broken pieces to rise and pass through the lower mesh blade 319 to cut the broken pieces again;

[0075] S4. The air discharged through the telescopic airbag 308 in the anti-blocking member passes through the nozzle 405 to blow away the broken pieces that have fallen onto the net-shaped blade 303 and are attached to the bottom of the upper pressing plate 104.

[0076] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
