Description

Technical Field

[0001] The utility model relates to the technical field of chemical raw material processing, in particular to a chemical raw material pressing and recycling device. Background Art

[0002] In the process of chemical raw material processing, it is often necessary to synthesize, purify and other operations on the processed raw materials to obtain materials with higher purity. In the process of operation, waste is often generated, and the waste contains more impurities, resulting in a certain hardness of the waste. After the waste is purified, it can still be recovered to obtain product materials. Therefore, before purification, the waste needs to be crushed and refined and then placed in a crystallization device for crystallization and purification again.

[0003] In the prior art, there is a utility model patent with a publication (announcement) number of CN216224675U and a name of a chemical raw material processing pressing and recycling device, which includes a pressing bin plate, a pressing groove is provided on the pressing bin plate, and a pressing component is assembled and connected in the pressing groove; the pressing component includes a transversely arranged driving screw, and a plurality of pressing pieces are slidably connected to the driving screw, and the pressing pieces all include a longitudinal column rod slidably connected to the driving screw, and the left and right ends of the longitudinal column rod are fixedly connected to the pressing plate; the front and rear ends of the driving screw are fixedly connected to the end seat body, and the top of the end seat body is assembled and connected to the cylinder; the cylinder barrel of the cylinder is fixedly connected to the side wall of the pressing bin plate through a connecting rod; two crushing components symmetrically arranged on the left and right are fixedly connected between the end seat bodies; the utility model can efficiently crush and refine the materials in the process of chemical raw material processing, and effectively improve the recycling efficiency of materials in chemical raw material processing.

[0004] The equipment of this patent can efficiently crush and refine materials during the processing of chemical raw materials. However, after crushing the chemical raw materials, the equipment of this patent does not screen the crushed chemical raw materials, resulting in chemical raw materials of different sizes being compressed uniformly, which makes it inconvenient for the equipment to maximize the compression of the volume of the chemical raw materials, reducing the overall practicality of the equipment. Utility Model Content

[0005] The utility model aims to provide a chemical raw material pressing and recovery device.

[0006] The technical problem solved by the utility model is that when the existing equipment compresses and recovers the chemical raw materials, it is inconvenient for the equipment to maximize the compression of the volume of the chemical raw materials because the chemical raw materials after crushing are not screened.

[0007] The utility model can be realized through the following technical scheme: a chemical raw material pressing recovery device comprises a recycling box, a pressing drawer is detachably installed at the bottom of the inner cavity of the recycling box, a crushing mechanism is arranged in the inner cavity of the recycling box, the crushing mechanism comprises a crushing roller rotatably connected to the inner cavity of the recycling box, a screening plate for screening the chemical raw materials after crushing is slidably connected to the inner cavity of the recycling box and located below the crushing roller, a hydraulic telescopic rod is fixedly installed at the bottom end of the screening plate, a lifting plate for pressing is fixedly installed at the output end of the hydraulic telescopic rod, a through hole penetrating through the inner cavity of the lifting plate is staggered with the screening hole in the screening plate, and the lifting plate at its bottom end can be synchronously moved by the movement of the screening plate, and since the aperture of the through hole in the inner cavity of the lifting plate is slightly larger than the aperture of the screening hole, the chemical raw materials after crushing can be conveniently and quickly entered into the inner cavity of the pressing drawer.

[0008] A further technical improvement of the utility model is that a linkage mechanism is arranged on the outer wall of the recycling box to make the crushing roller rotate and the screening plate slide up and down in the inner cavity of the recycling box. The linkage mechanism includes a rotating rod rotatably connected to the inner cavity of the recycling box and located between the crushing roller and the screening plate. One end of the crushing shaft in the center of the rotating rod and the crushing roller penetrates the recycling box and extends to the outer wall of the recycling box. The rotating rod and the crushing roller are connected by a belt transmission. Eccentric wheels abutting the screening plate are fixedly sleeved on both sides of the outer wall of the rotating rod.

[0009] A further technical improvement of the utility model is that the belt member comprises pulleys which are respectively fixedly sleeved on the rotating rod and the outer wall of the crushing shaft, and the two pulleys are connected by belt transmission.

[0010] A further technical improvement of the utility model is that a push plate for closing the inner hole of the lifting plate is slidably connected through the back of the recycling box. When the crushed chemical raw materials are not screened, the push plate does not contact the lifting plate. After the screening of the crushed chemical raw materials is completed, the two can be installed by sliding the push plate, and the two can be combined into one after installation.

[0011] A further technical improvement of the utility model is that a limiting mechanism is arranged on one side of the push plate opposite to the lifting plate, the limiting mechanism comprises at least two sliding blocks fixedly connected to the push plate, the inner cavity of the lifting plate is provided with sliding grooves for sliding of the sliding blocks, the inner cavity of the sliding blocks is elastically slidably connected to the limiting blocks, the inner cavity of the lifting plate is provided with limiting grooves cooperating with the limiting blocks, the limiting grooves are connected with the sliding grooves, and the setting of the limiting mechanism facilitates the installation of the push plate and the lifting plate, thereby facilitating the subsequent material pressing work of the equipment.

[0012] A further technical improvement of the utility model is that a lever is fixedly installed on the outer wall of the slider, and the end of the lever away from the slider passes through the slider and the lifting plate in sequence and extends to the outside of the lifting plate. The two levers are slid, and the limit of the push plate is conveniently released by moving the levers. After the limit is released, the push plate is reset, thereby facilitating the recycling of the equipment.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The utility model facilitates the crushing of chemical raw materials through the rotation of the crushing roller. The crushed chemical raw materials will fall onto the screening plate. The multiple evenly distributed screening holes opened in the inner cavity of the screening plate facilitate the screening of qualified chemical raw materials. While the crushing shaft rotates, the belt drives the rotating rod to rotate synchronously through the pulley through the transmission action of the belt. When the rotating rod rotates, it drives the two eccentric wheels fixed on its outer wall to rotate synchronously. The rotation of the eccentric wheel facilitates the intermittent extrusion of the sliding plate, and then the sliding plate makes the screening plate slide back and forth up and down in the inner cavity of the recycling box. The movement of the screening plate allows the chemical raw materials falling thereon to be quickly screened to avoid blockage. By screening the crushed chemical raw materials, it is convenient to unify the specifications of the pressed chemical raw materials, which is conducive to maximizing the compression of the volume of the chemical raw materials and is convenient for the staff to use.

[0015] 2. The utility model slides the push plate so that the slider at the top of the push plate enters the sliding groove of the inner cavity of the lifting plate. As the push plate continues to slide, the slider slides into the end of the inner cavity of the sliding groove. At this time, the elastic force of the squeezing spring in the inner cavity of the slider causes the limit block to move to the inner cavity of the corresponding limit groove, which not only facilitates the installation of the lifting plate and the push plate as a whole, but also facilitates the closing of multiple through holes in the inner cavity of the lifting plate through the push plate. After closing, the power supply of the hydraulic telescopic rod is turned on, and the chemical raw materials in the inner cavity of the pressing drawer are pressed conveniently through the hydraulic telescopic rod, which is beneficial to ensure the overall pressing effect of the equipment and facilitates improving the overall practicality of the equipment.

[0034] Inner grooves 23 are provided on both sides of the inner cavity of the recycling box 1. A crushing shaft 21 and a rotating rod 25 are rotatably connected to the outer wall of the recycling box 1. The crushing shaft 21 is located above the rotating rod 25. One end of the crushing shaft 21 and the rotating rod 25 respectively penetrates the recycling box 1 and the inner groove 23 and extends to the inner cavity of the inner groove 23. The crushing shaft 21 and the rotating rod 25 extend to the inner cavity of the inner groove 23 and are rotatably connected to the inner wall of the inner groove 23 through bearings. A symmetrical fixed sleeve is arranged on the outer wall of the rotating rod 25 and located in the inner cavity of the inner groove 23. There are two eccentric wheels 26, and a sliding plate 28 abutting against the eccentric wheel 26 is slidably connected between the two inner side walls of the inner groove 23. At least one supporting spring 27 fixedly connected to the sliding plate 28 is fixedly installed on the inner wall of the inner groove 23. A crushing roller 22 is fixedly sleeved on the outer wall of the crushing shaft 21 and located in the inner cavity of the inner groove 23. A screening plate 29 is slidably connected to the inner cavity of the inner groove 23 and located below the rotating rod 25. Transmission blocks fixedly connected to the outer wall of the sliding plate 28 are fixedly installed on both side walls of the screening plate 29.

[0035] A servo motor 2 is fixedly mounted on the outer wall of the recycling box 1 via an L-shaped mounting plate. The output end of the servo motor 2 is fixedly connected to the crushing shaft 21. A belt member is arranged between the crushing shaft 21 and the rotating rod 25. The belt member includes two pulleys 24 which are respectively fixedly mounted on the outer walls of the crushing shaft 21 and the rotating rod 25. The two pulleys 24 are connected via a belt 241.

[0036] A hydraulic telescopic rod 210 is fixedly installed on the side of the screening plate 29 away from the rotating rod 25, and the output end of the hydraulic telescopic rod 210 is fixedly connected to a lifting plate 211. The inner cavity of the screening plate 29 is penetrated by a plurality of evenly distributed screening holes 212, and the inner cavity of the lifting plate 211 is penetrated by a through hole 213 that is staggered with the screening hole 212, wherein the aperture of the through hole 213 is slightly larger than the aperture of the screening hole 212.

[0037] The back of the recycling box 1 is slidably connected with a push plate 4 for closing the inner cavity through hole 213 of the lifting plate 211. The push plate 4 is symmetrically fixedly connected with two sliders 41 on one side of the lifting plate 211.

[0038] A pressing drawer 6 for receiving crushed qualified materials is slidably connected to the bottom of the inner wall of the recovery box 1, and the pressing drawer 6 and the recovery box 1 are fixed by bolts.

[0039] When the utility model is in use, the chemical raw materials to be processed are put into the inner cavity of the recycling box 1 through the feed hopper 3, and the power supply of the servo motor 2 is turned on to rotate the crushing shaft 21. The rotation of the crushing shaft 21 drives the crushing roller 22 to rotate synchronously. The chemical raw materials are crushed by the rotation of the crushing roller 22. The crushed chemical raw materials will fall on the screening plate 29. The multiple evenly distributed screening holes 212 opened in the inner cavity of the screening plate 29 are convenient for screening the chemical raw materials with qualified crushing. When the crushing shaft 21 rotates, the rotating rod 25 is driven to rotate synchronously through the pulley 24 through the transmission effect of the belt 241. When the rotating rod 25 rotates, it drives the two eccentric wheels 26 fixedly sleeved on its outer wall to rotate synchronously. The rotation of the eccentric wheel 26 facilitates the intermittent extrusion of the sliding plate 28, and then the sliding plate 28 makes the screening plate 29 slide back and forth up and down in the inner cavity of the recycling box 1. The chemical raw materials falling on it can be quickly screened through the movement of the screening plate 29 to avoid its blockage.

[0040] The movement of the screening plate 29 can make the lifting plate 211 at its bottom move synchronously. Since the aperture of the through hole 213 in the inner cavity of the lifting plate 211 is slightly larger than the aperture of the screening hole 212, the chemical raw materials after crushing can be quickly entered into the inner cavity of the pressing drawer 6. After all the chemical raw materials after crushing have entered the inner cavity of the pressing drawer 6, the push plate 4 is slid to make the slider 41 at the top of the push plate 4 enter the sliding groove 42 in the inner cavity of the lifting plate 211. As the push plate 4 continues to slide, the slider 41 slides into the inner cavity of the lifting plate 211. At the end of the inner cavity of the sliding groove 42, at this time, the elastic force of the squeezing spring in the inner cavity of the slider 41 causes the limit block 44 to move to the inner cavity of the corresponding limit groove 45, so that it is not only convenient to install the lifting plate 211 and the push plate 4 as one, but also convenient to close the multiple through holes 213 in the inner cavity of the lifting plate 211 through the push plate 4, and after closing, the power supply of the hydraulic telescopic rod 210 is turned on, and the chemical raw materials in the inner cavity of the pressing drawer 6 are conveniently pressed through the hydraulic telescopic rod 210. After the pressing is completed, it can be taken out by opening and closing the door 5;

[0041] In subsequent use, the two levers 46 can be moved by opening and closing the door 5. The limit of the push plate 4 can be easily released by moving the lever 46. After the limit is released, the push plate 4 can be reset, thereby facilitating the subsequent use of the device.
