This device solves the problem that general waste circuit board recycling devices cannot completely remove toxic substances from the circuit boards, causing damage to the ecological environment during the processing of waste circuit boards. However, when the circuit boards are crushed, fragments often fly out of the feed inlet, which can easily injure workers. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a circuit board recycling and crushing device that prevents splashing, so as to solve the problems existing in the background art.
[0005] This utility model provides the following technical solution: a splash-proof circuit board recycling and crushing device, including a housing, a crusher fixed to the bottom of the housing by bolts, a feeding rack welded to one side of the outer wall of the housing, the bottom of the feeding rack inclined towards the housing, a feeding port opened on one side of the housing, a plurality of first baffles rotatably connected to the top inner wall of the feeding port by hinges, and the height of the first baffles being the same as the height of the feeding port, a plurality of third baffles fixed between the two inner walls of the housing by bolts, the plurality of third baffles being inclined, and the channel formed between two adjacent third baffles facing away from the inclined direction of the feeding rack guiding the material, a connecting plate fixed to the housing welded to one side of the leftmost third baffle, and a dust removal component for reducing dust generated after the circuit board is crushed on the top inner wall of the housing.
[0006] As a further embodiment of this utility model, the dust removal assembly includes a liquid distribution pipe fixed between the inner walls of both sides of the housing by bolts, with multiple nozzles fixed at the bottom of the liquid distribution pipe at an angle, and an external water pipe connected to an external water pump fixed on one side of the liquid distribution pipe by a clamp.
[0007] As a further embodiment of this utility model, multiple second baffles are fixed between the inner walls of both sides of the housing by bolts, and the multiple second baffles are inclined and the adjacent two second baffles are staggered and overlapped. A drain port is opened on one side of the housing, and the bottom of the drain port is flush with the bottom of the rightmost second baffle.
[0008] As a further embodiment of this utility model, the bottom of one of the second baffles is rotatably connected to a plurality of U-shaped perforated plates via a hinge, and one side of the plurality of first baffles is rotatably connected to a straight perforated plate via a hinge, and the straight perforated plate slides within the U-shaped perforated plate.
[0009] As a further embodiment of this utility model, a baffle is welded between the inner walls of the two sides of the feeding rack, and the length of the baffle is not shorter than the distance between the feed inlet and the top outer wall of the housing, and the baffle is in contact with the first baffle.

At the same time, the channel formed between two adjacent third baffles does not face the feed inlet, so that the debris flying out of the channel cannot fly to the feed inlet and thus cannot fly out of the shell, thereby improving the protective effect of the device.
[0015] 2. This utility model is equipped with a dust removal component. An external water pump draws water into the liquid distribution pipe through an external water pipe and sprays it out from the nozzle, thereby reducing the dust generated by crushing circuit boards and further improving the protective effect of the device.
[0016] 3. By providing a second baffle, the splashed fragments are blocked, reducing the flight distance of the fragments and making it easier for them to return to the crusher.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] Reference Figures 1-4This utility model provides a splash-proof circuit board recycling and crushing device, including a housing 1. A crusher 2 is bolted to the bottom of the housing 1. The crusher 2 is existing technology, consisting of a crushing roller, a housing, a belt, pulleys, and a motor, etc., and is an existing electrical device, which will not be described in detail here. A feeding rack 4 is welded to one outer wall of the housing 1. The bottom of the feeding rack 4 is inclined towards the housing 1. A feeding port is opened on one side of the housing 1. Multiple first baffles 6 are rotatably connected to the top inner wall of the feeding port through hinges, and the height of the first baffles 6 is the same as the height of the feeding port. A counterweight 12 is bolted to one side of each of the multiple first baffles 6. The counterweight 12 is used to increase the gravity of the rotation of the first baffles 6, so that the first baffles 6 can quickly return to their original position after the circuit boards are fed in. Multiple third baffles 10 are bolted between the inner walls of the two sides of the housing 1, and the multiple third baffles 10 are inclined, and the distance between two adjacent third baffles 10 is... The channel formed between the three baffles faces away from the inclined direction of the feeding rack 4. A connecting plate 11 fixed to the housing 1 is welded to one side of the third baffle 10 on the far left. The top inner wall of the housing 1 is equipped with a dust removal component to reduce the dust generated after the circuit board is crushed. When the circuit board is recycled and crushed, the circuit board is first placed on the feeding rack 4 and pushed towards the feed inlet. The circuit board pushes the first baffle 6 to rotate, thereby passing through the feed inlet, sliding into the housing 1, and entering the crusher 2 through the channel between the third baffles 10. The crusher 2 is started and crushes the circuit board. The fragments that fly out of the crushed circuit board are blocked by the third baffle 10, so they cannot fly directly out of the feed inlet. At the same time, the channel formed between two adjacent third baffles 10 does not face the feed inlet, so the fragments flying out of the channel cannot fly to the feed inlet, thus preventing them from flying out of the housing 1, improving the protective effect of the device.
[0024] In this utility model, the dust removal component includes a liquid distribution pipe 7 fixed between the inner walls of both sides of the housing 1 by bolts. Multiple nozzles 13 are fixed at the bottom of the liquid distribution pipe 7 at an angle. An external water pipe 3 connected to an external water pump is fixed to one side of the liquid distribution pipe 7 by a clamp. When the external water pump is started, the external water pump draws water into the liquid distribution pipe 7 through the external water pipe 3 and sprays it out from the nozzles 13, thereby reducing the dust generated by crushing the circuit board and further improving the protective effect of the device.
[0025] Multiple second baffles 8 are bolted between the inner walls of the two sides of the housing 1. The multiple second baffles 8 are inclined and the adjacent two second baffles 8 are staggered and overlapped. A drain port 9 is opened on one side of the housing 1, and the bottom of the drain port 9 is flush with the bottom of the rightmost second baffle 8. After the splashed fragments fly out from the channel formed between the two adjacent third baffles 10, they will be blocked by the second baffles 8, reducing the flying distance of the fragments and making it easier for the fragments to return to the crusher 2. At the same time, the water and dust sprayed from the nozzle 13 will flow through the guide of the second baffles 8 to the drain port 9, thereby achieving solid-liquid separation, thus preventing the crushed circuit board fragments from adhering to the crusher 2 and improving the environmental friendliness of the device.
[0026] In this invention, the bottom of one of the second baffles 8 is hinged to a plurality of U-shaped perforated plates 16, and one side of the plurality of first baffles 6 is hinged to a straight perforated plate 17, which slides within the U-shaped perforated plate 16. During the rotation of the first baffle 6, the first baffle 6 pushes the straight perforated plate 17 into the U-shaped perforated plate 16, thereby preventing the first baffle 6 from rotating and allowing it to rotate. Simultaneously, the straight perforated plate 17 and the U-shaped perforated plate 16 prevent flying debris from impacting the hinge of the first baffle 6, thus preventing the first baffle 6 from rotating. The baffle 6 can maintain rotation for a long time, maintain the performance of the first baffle 6, and improve the operational stability of the device. A partition 14 is welded to one side of the second baffle 8 located on the far left. A flow port is formed between the partition 14 and the housing 1. Dust can pass through the straight perforated plate 17 and the U-shaped perforated plate 16 and flow from the flow port to the top of the second baffle 8, where it is then adsorbed by the sprayed water. A guide frame 15 is fixed to the top of the housing 1 by bolts, and the guide frame 15 is located above the flow port to change the airflow direction in the flow port, so that the dust in the flow port flows to the nozzle 13.
[0027] In this utility model, a baffle 5 is welded between the inner walls of both sides of the feeding rack 4, and the length of the baffle 5 is not shorter than the distance between the feed inlet and the top outer wall of the housing 1. The baffle 5 is in contact with the first baffle 6, and the baffle 5 restricts the rotation angle of the first baffle 6 so that the first baffle 6 just contacts the feeding rack 4, thereby avoiding the phenomenon of the first baffle 6 getting stuck due to excessive contact between the first baffle 6 and the feeding rack 4.
[0028] The use of this utility model involves the following steps:
[0029] S1: First, place the circuit board on the feeding rack 4, push the circuit board to move towards the feed inlet, the circuit board pushes the first baffle 6 to rotate, so that it passes through the feed inlet, slides into the housing 1, and enters the crusher 2 through the channel between the third baffle 10.
[0030] S2: Start the crusher 2. The crusher 2 crushes the circuit board. The fragments that fly out of the crushed circuit board will be blocked by the third baffle 10, so they cannot fly out directly from the feed inlet. At the same time, the channel formed between two adjacent third baffles 10 does not face the feed inlet, so the fragments flying out from the channel cannot fly to the feed inlet, and thus cannot fly out of the housing 1, so they cannot cause harm to the staff.
[0031] S3: Start the external water pump. The external water pump draws water into the liquid distribution pipe 7 through the external water pipe 3 and sprays it out from the nozzle 13 to reduce the dust generated by crushing the circuit board. The water sprayed from the nozzle 13 mixes with the dust and flows through the guide of the second baffle 8 to the drain port 9 and is discharged from the drain port 9, thus achieving solid-liquid separation.
[0032] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change.
