Description

Technical Field

[0001] This invention belongs to the field of destruction device technology, specifically a destruction device and method for waste electricity metering equipment. Background Technology

[0002] With the continuous development of the power industry and the ongoing advancement of smart grids, the number of waste electricity metering devices (such as electricity meters) is increasing. Some manufacturers are using traditional crushing equipment to crush and destroy these devices. This process involves using a hydraulic rod to drive a lower pressure plate to crush the outer casing of the metering device, thereby improving the resource recycling rate.

[0003] In existing technologies, the casing, circuit boards, and other components of the metering equipment are disassembled and sorted. The casing is then crushed separately. During crushing, a lower pressure plate crushes the casing placed on a workbench. However, the crushed casing fragments are of varying sizes or are quite large, which complicates subsequent sorting. In later processing, additional treatment is required for fragments of varying sizes or larger fragments (such as screening, further crushing of larger fragments), increasing production steps and time. Therefore, we propose a device and method for destroying waste electricity metering equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a device and method for destroying waste electricity metering equipment, so as to solve the technical problems mentioned in the background art.

[0007] A lower hydraulic rod is fixedly installed at the bottom of the inner wall of the frame, and a lower pressure plate is fixedly installed at the working end of the lower hydraulic rod, which is used to push the shell fragments cut by the mesh blade upward and cut them again by the lower mesh blade.

[0008] The anti-clogging component, located on the upper pressure plate, is used to clear debris that may clog the inside of the mesh blade, blade holder, and lower mesh blade.

[0009] Preferably, the anti-blocking component includes a middle plate disposed above the upper pressure plate and an upper plate disposed above the middle plate. Multiple sets of inserts are fixedly disposed at the bottom of the middle plate, and two sets of telescopic airbags are fixedly disposed between the upper plate and the middle plate.

[0010] Connecting blocks are fixedly installed on both sides of the upper pressure plate, and a vertical plate is fixedly installed on the top of the connecting blocks. An inlet hose is fixedly installed on the front of the telescopic airbag.

[0012] Preferably, two sets of connecting springs are fixedly provided between the pipe head and the partition, and a long baffle and two sets of short baffles are fixedly provided on the inner wall of the frame.

[0013] Preferably, the back of the telescopic airbag is provided with a purge assembly, which includes a pipe fixed to the back of the connector head and a horizontal pipe slidably disposed on the back of the upper pressure plate. A telescopic tube is fixedly disposed on the pipe, and a lower tube is fixedly disposed at the bottom of the telescopic tube.

[0014] Preferably, two sets of fixing rings are fixedly installed on the back of the upper pressure plate, a baffle strip is fixedly installed inside the lower tube, and multiple sets of nozzles are evenly distributed at the bottom of the horizontal tube along the length of the horizontal tube.

[0015] Preferably, both sides of the frame are provided with limiting members to limit the connection block. The limiting members include two sets of U-shaped plates fixed on the two sides of the frame. The U-shaped plates are provided with limiting blocks and iron blocks inside. A mounting spring is fixed between the top of the limiting blocks and the top of the electromagnet.

[0016] Preferably, the top of both sides of the frame is provided with a sliding groove for the connecting block to slide up and down. A blocking component is provided on the sliding groove. The blocking component includes a vertical baffle fixed to the bottom of the connecting block. Two sets of L-shaped frames are fixedly provided on both sides of the frame. A vertical frame is fixedly provided on the front of the vertical baffle.

[0017] Preferably, the front and back of the frame are rotatably provided with cover plates, and an upper hydraulic rod is fixedly provided on the frame.

[0018] This invention also discloses a method for destroying waste electricity metering equipment, specifically including the following steps:

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

[0020] S2. After the plastic shell is cut into pieces by the mesh blade, it falls onto the lower pressure plate below. Then, the anti-blocking component squeezes and clears some of the fragments that are blocking the mesh blade, blade holder and lower mesh blade.

[0021] S3. The lower pressure plate is driven to rise by the lower hydraulic rod, which in turn causes the fragments to rise and be cut again by the lower mesh blade.

[0022] S4. The air discharged through the telescopic airbag in the anti-blocking component blows through the nozzle to sweep away the debris that has fallen onto the mesh blade and is attached to the bottom of the upper pressure plate.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] (1) The present invention, through the designed shredding mechanism, enables the plastic shell to be cut into appropriately sized pieces through the cutting of the net-shaped blade and the lower net-shaped blade and the pushing of the upper and lower pressure plates. This facilitates the shredding into uniformly sized pieces, significantly improves the crushing efficiency, and reduces the possibility of subsequent shredding. The telescopic airbag pushes the insert to clear the pieces stuck inside the net-shaped blade, the lower net-shaped blade and the blade holder. The blade holder is fixed to the frame with bolts, and net-shaped blades and lower net-shaped blades with different mesh sizes can be replaced as needed.

[0025] (2) The present invention uses a designed blowing component to blow air through multiple nozzles onto the lower surface of the pressure plate and the upper surface of the mesh blade after the plastic shell is crushed. This blows away some of the attached fragments, cleans them in time to avoid affecting the subsequent cutting and crushing operations, and makes full use of the gas in the telescopic airbag.

[0026] (3) The present invention uses a limiting component to limit the connection block when the operator is feeding the material. This prevents the hydraulic rod from being accidentally activated and causing injury to the operator when the plastic shell is placed on the surface of the mesh blade. This increases the safety of the operation. When the crushing operation begins, the electromagnet is activated to attract the iron block and move it, so that one end of the limiting block is disengaged from the limiting groove, making the operation convenient.

[0027] (4) The present invention uses a designed blocking component. During the crushing and cutting of the plastic shell by pressing down the upper pressure plate, the vertical baffles on both sides of the frame move with the movement of the connecting block to block the fragments that splash out of the sliding grooves on both sides of the frame, thus preventing the fragments from splashing out and increasing safety.

Detailed Implementation

[0044] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Example 1

[0046] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9 This invention provides a technical solution: a device for destroying waste electricity metering equipment, including a frame 102 and an upper pressure plate 104 disposed inside the frame 102. The frame 102 is provided with a shredding mechanism, which includes a cutting component and an anti-blocking component. The cutting component includes a blade holder 306 disposed inside the frame 102. Both sides of the frame 102 are connected by bolts through threads, and the working ends of the bolts extend into the interior of the blade holder 306. The blade holder 306 can be disassembled and assembled by disassembling and assembling the bolts, thereby replacing the mesh blades 303 and lower mesh blades 319 with different mesh sizes. The upper and lower surfaces of the blade holder 306 are respectively fixedly provided with mesh blades 303 and lower mesh blades 319 for repeatedly shredding the outer shell.

[0047] A lower hydraulic rod 317 is fixedly installed at the bottom of the inner wall of the frame 102. A lower pressure plate 318 is fixedly installed at the working end of the lower hydraulic rod 317, which is used to push the shell fragments cut by the mesh blade 303 upward and then cut them again by the lower mesh blade 319.

[0048] Example 2

[0049] Please refer to Example 1. Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 The anti-blocking component includes a middle plate 301 disposed above the upper pressure plate 104 and an upper plate 302 disposed above the middle plate 301. The two sides of the middle plate 301 are connected to the upper pressure plate 104 below by two sets of fixed springs, which enable the insert post 316 and the middle plate 301 to be reset by the fixed springs when rising and resetting, so that the insert post 316 and the middle plate 301 can move upward to their original positions. Multiple sets of insert posts 316 are fixedly disposed at the bottom of the middle plate 301. The bottom of the insert post 316 can pass through the interior of the upper pressure plate 104. Two sets of telescopic airbags 308 are fixedly disposed between the upper plate 302 and the middle plate 301.

[0050] Connecting blocks 101 are fixedly installed on both sides of the upper pressure plate 104. A vertical plate 307 is fixedly installed on the top of the connecting block 101. The upper plate 302 is fixed on the vertical plate 307. An inlet hose 300 is fixedly installed on the front of the telescopic airbag 308. The end of the inlet hose 300 is connected to an external high-pressure blower. A connecting pipe 310 is fixedly installed between the two sets of L-shaped pipes.

[0051] Both the front and back sides of the upper plate 302 are fixedly provided with L-shaped tubes. The ends of the L-shaped tubes are fixedly provided with connector heads 313. A partition 314 is slidably provided inside the connector head 313. When the partition 314 is inserted into the connector head 313, the connector head 313 is closed. When the partition 314 is opened, the connector head 313 is open. A lifting plate 312 is fixedly provided on one side of the partition 314. There is only one set of lifting plates 312 and one set of long baffles 304 on the front side of the equipment. There are two sets of lifting plates 312 and two sets of short baffles 305 on the back side of the equipment.

[0052] Two sets of connecting springs 315 are fixedly installed between the connector 313 and the partition 314. A long baffle 304 and two sets of short baffles 305 are fixedly installed on the inner wall of the frame 102. The bottom of the long baffle 304 is a sloping structure, which makes it easy for the lifting plate 312 on the front to contact the long baffle 304. The top of the short baffle 305 is a sloping structure, which makes it easy for the lifting plate 312 on the back to contact the short baffle 305. The end of the lifting plate 312 can contact the surface of the long baffle 304 and the short baffle 305.

[0053] This invention utilizes a designed shredding mechanism. Through the cutting of the mesh blades 303 and 319, and the pushing action of the upper pressure plate 104 and 318, the plastic shell can be cut into appropriately sized pieces in one or two passes, significantly improving crushing efficiency and reducing the likelihood of subsequent shredding. The telescopic airbag 308 pushes the insert 316 to clear any pieces stuck inside the mesh blades 303, 319, and the blade holder 306. The blade holder 306 is bolted to the frame 102. Different mesh sizes of the mesh blades 303 and 319 can be replaced as needed to facilitate shredding into uniformly sized pieces.

[0054] In summary, the cover plate 103 is opened, and the plastic shell to be crushed is placed on the upper surface of the mesh blade 303. Then the cover plate 103 is closed to start crushing and cutting. The two sets of upper hydraulic rods 100 are activated to drive the connecting block 101 to descend, which in turn drives the upper pressure plate 104, upper plate 302, and middle plate 301 to descend and move. Then the upper pressure plate 104 can contact and press the plastic shell. At this time, the plastic shell is squeezed and produces large fragments. Then, as the upper pressure plate 104 continues to press down, the plastic shell descends and passes through the mesh blade 303. The mesh blade 303 cuts it into fragments of appropriate size, and then the fragments fall onto the surface of the lower pressure plate 318 below.

[0055] As the upper pressure plate 104 descends, it also causes the lifting plates 312 at the front and back of the telescopic airbag 308 to descend as well. Before the upper pressure plate 104 descends, the end of the lifting plate 312 at the front of the telescopic airbag 308 is in contact with the surface of the long baffle plate 304. At this time, the partition plate 314 is in the closed state inside the connecting head 313, and the connecting spring 315 at the front of the telescopic airbag 308 is in a compressed state. Meanwhile, the lifting plate 312 at the back of the telescopic airbag 308 is not in contact with the short baffle plate 305. At this time, the partition plate 314 is in the open state inside the connecting head 313, and the connecting spring 315 at the back of the telescopic airbag 308 is in a compressed state. As the upper pressure plate 104 descends, it causes the lifting plates 312 at the front of the telescopic airbag 308 to descend as well. After the pressure plate 104 descends to a certain position, the end of the lifting plate 312 located on the front of the telescopic airbag 308 is away from the surface of the long barrier plate 304. Then, with the connecting spring 315 resetting, it drives the partition plate 314 and the lifting plate 312 to move to the right. At this time, the inside of the connecting pipe 313 is in the open state, and then gas is quickly injected into the telescopic airbag 308 on the right through the inlet hose 300 and the connecting pipe 313. Meanwhile, the telescopic airbag 308 on the left is injected with gas through the connecting pipe 310. At the same time, during the descent of the upper pressure plate 104, the end of the lifting plate 312 located on the back of the telescopic airbag 308 contacts the short barrier plate 305. The rear lifting plate 312 moves closer to the connecting head 313, causing the partition 314 to move. The partition 314 then engages with and seals the interior of the connecting head 313, preventing the gas inflated into the telescopic airbag 308 from escaping. As the telescopic airbag 308 inflates, its height increases, pushing the lower middle plate 301 and the multiple sets of inserts 316 at its bottom downwards. The bottoms of the inserts 316 then pass through the mesh blade 303, the blade holder 306, and the lower mesh blade 319, pushing out the blocked fragments to clear the blockage. This allows the plastic shell to be crushed and shredded into suitable sizes. Then, the process is repeated in reverse order. When the upper pressure plate 104 rises, the lifting plate 312 located on the front of the telescopic airbag 308 contacts the long baffle plate 304, which drives the partition plate 314 to move and block the inside of the connector head 313, stopping the inlet hose 300 from continuing to inflate the telescopic airbag 308. Meanwhile, the lifting plate 312 located on the back of the telescopic airbag 308 disengages from the long baffle plate 304, which in turn drives the partition plate 314 to move and open the inside of the connector head 313. At this time, the gas inside the telescopic airbag 308 is discharged outward. Then the middle plate 301 and the insert post 316 move upward to reset. Subsequently, the insert post 316 moves to its original position, and the subsequent crushing operation can be carried out again. Finally, the fragments that fall on the lower pressure plate 318 are removed.

[0056] If, after being pressed down by the upper pressure plate 104 and shredded by the mesh blade 303, some of the fragments are vertical strips, these vertical strips fall onto the lower pressure plate 318. After falling onto the lower pressure plate 318, the vertical strips tilt to a horizontal position. Then, the lower hydraulic rod 317 is activated to drive the lower pressure plate 318 upwards, causing the horizontally flat fragments on the surface of the lower pressure plate 318 to be shredded to a suitable size by the lower mesh blade 319. 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 portion gets stuck in the mesh blade 303, the blade holder 306, or the lower mesh blade 319. Then, the upper pressure plate 104 presses down in conjunction with the insert 316 to push the fragments stuck in the mesh blade 303, the blade holder 306, or the lower mesh blade 319 onto the lower pressure plate 318. Finally, the fragments can be removed.

[0057] Example 3

[0058] Please refer to Example 2. Figure 2 , Figure 3 , Figure 8 , Figure 10 , Figure 11 , Figure 14 and Figure 15 The back of the telescopic airbag 308 is provided with a purge assembly, which includes a pipe 400 fixed to the back of the connector 313 and a horizontal pipe 401 slidably disposed on the back of the upper pressure plate 104. A telescopic pipe 402 is fixedly disposed on the pipe 400, and a lower pipe 404 is fixedly disposed at the bottom of the telescopic pipe 402.

[0059] Two sets of fixing rings 403 are fixedly installed on the back of the upper pressure plate 104. The bottom of the lower tube 404 passes through the inside of the fixing rings 403 and extends into the inside of the horizontal tube 401. A baffle strip 406 is fixedly installed inside the lower tube 404. Multiple sets of nozzles 405 are evenly distributed at the bottom of the horizontal tube 401 along the length of the horizontal tube 401.

[0060] The present invention uses a designed blowing assembly to blow away any attached fragments after the plastic shell is crushed. The gas inside the telescopic airbag 308 blows through multiple sets of nozzles 405 onto the lower surface of the pressure plate 104 and the upper surface of the mesh blade 303, thus cleaning up the fragments in time to avoid affecting subsequent cutting and crushing operations, and making full use of the gas inside the telescopic airbag 308.

[0061] In summary, when the internal part of the connecting pipe 313 on the back of the telescopic airbag 308 opens to release air, the upper pressure plate 104 begins to move upward. The released gas passes through the exhaust pipe 400, telescopic pipe 402, lower pipe 404, and horizontal pipe 401. The gas in the telescopic pipe 402 comes into contact with the baffle strip 406 as it passes through the lower pipe 404. At this time, due to the impact force of the gas, the baffle strip 406 is pushed downward, which in turn drives the external lower pipe 404, horizontal pipe 401, and nozzle 4... 05 Moves downwards, and then multiple sets of nozzles 405 descend to the lower surface of the upper pressure plate 104. At this time, the nozzles 405 begin to blow gas toward the mesh blade 303 and the lower surface of the upper pressure plate 104 to sweep away the attached debris. When the gas in the telescopic airbag 308 weakens, the impact on the baffle 406 decreases. At this time, the lower pipe 404 rises, driving the horizontal pipe 401 and multiple sets of nozzles 405 to rise to their original positions, without affecting the normal use of the upper pressure plate 104.

[0062] Example 4

[0063] Please refer to Example 3. Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 Both sides of the frame 102 are provided with limiting components to limit the connection block 101. The limiting components include two sets of U-shaped plates fixed on both sides of the frame 102. The U-shaped plates are provided with a limiting long block 500 and an iron block 501 inside. The iron block 501 is fixed on the limiting long block 500. The connection block 101 is provided with a limiting groove for the end of the limiting long block 500 to pass through. A mounting spring 503 is fixed between the top of the limiting long block 500 and the top of the electromagnet 502. The mounting spring 503 is made of aluminum.

[0064] This invention utilizes a designed limiting component. During operation, when the operator is feeding material, one end of the limiting block 500 is inserted into the limiting groove in the connecting block 101 to limit the connection block 101. This prevents accidental activation of the upper hydraulic rod 100 during the process of placing the plastic shell onto the surface of the mesh blade 303, thus avoiding accidental injury to the operator and increasing safety during operation. When the crushing operation begins, the electromagnet 502 is activated to attract the iron block 501 to move, causing one end of the limiting block 500 to disengage from the limiting groove, facilitating operation.

[0065] In summary, when the plastic shell is placed onto the mesh blade 303, the electromagnet 502 is turned off, and the iron block 501 is no longer magnetically attracted to the electromagnet 502. Then, the mounting spring 503 compressed above the electromagnet 502 is reset, pushing the iron block 501 and one end of the limiting block 500 on the iron block 501 to move closer to the connecting block 101 and insert into the limiting groove. At this time, the connecting block 101 can be limited, thereby limiting the upper hydraulic rod 100, avoiding the situation where the upper hydraulic rod 100 is accidentally activated and causes accidental injury to the operator. When the crushing operation begins, the operation can be carried out in reverse order.

[0066] The top of both sides of the frame 102 is provided with a sliding groove for the connecting block 101 to slide up and down. The sliding groove is provided with a blocking component, including a vertical baffle 200 fixed to the bottom of the connecting block 101. Two sets of L-shaped frames 201 are fixedly provided on both sides of the frame 102. A vertical frame 202 is fixedly provided on the front of the vertical baffle 200. The vertical frame 202 can slide up and down on the L-shaped frame 201.

[0067] The present invention uses a designed blocking component. During the crushing and cutting of the plastic shell by the pressure plate 104, the vertical baffles 200 on both sides of the frame 102 move with the movement of the connecting block 101 to block the fragments that splash out of the sliding grooves on both sides of the frame 102, thus preventing the fragments from splashing out and increasing safety.

[0068] In summary, when the connecting block 101 moves downward in the chute, it will cause the vertical baffle 200 to descend, which in turn will cause the two sets of vertical frames 202 on the vertical baffle 200 to slide within the L-shaped frame 201. Then, when the upper pressure plate 104 is close to the placed plastic shell, the vertical baffle 200 can cover the exposed chute area below the connecting block 101 and block the subsequent flying fragments.

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

[0070] Example 5

[0071] This invention also discloses a method for destroying waste electricity metering equipment, specifically including the following steps:

[0072] S1. Place the plastic shell of the metering device on the mesh blade 303 in the crushing device, and then start the upper hydraulic rod 100 to drive the upper pressure plate 104 to descend and crush the plastic shell;

[0073] S2. After the plastic shell is cut into fragments by the mesh blade 303, it falls onto the lower pressure plate 318 below. Then, the anti-blocking component squeezes and clears the fragments that are partially blocked in the mesh blade 303, the blade holder 306 and the lower mesh blade 319.

[0074] S3. The lower pressure plate 318 is driven to rise by the lower hydraulic rod 317, which in turn causes the fragments to rise and be cut again by the lower mesh blade 319.

[0075] S4. The air discharged through the telescopic airbag 308 in the anti-blocking component blows away the fragments that have fallen onto the mesh blade 303 and are attached to the bottom of the upper pressure plate 104 through the nozzle 405.

[0076] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
