Description

Technical Field

[0001] This utility model relates to the field of crushing device technology, specifically to a material crushing device. Background Technology

[0002] Palladium-on-carbon catalysts are widely used in petrochemical, environmental protection, and other fields. They are mainly formed by the composite of a carbon support and palladium metal particles, and possess significant catalytic activity. During the preparation and application of palladium-on-carbon catalysts, pulverization is often necessary to achieve better catalytic performance.

[0003] For example, patent CN219836617U discloses a material crushing device for palladium-carbon catalyst processing, including a crushing chamber. A feed pipe is fixedly connected to the inner top wall of the crushing chamber, with one end extending through to the outside of the crushing chamber. By pouring lumpy material into the crushing chamber through the feed pipe, the material can be crushed. However, this device has some shortcomings. In actual use, the material enters the crushing system directly through the feed pipe, which easily leads to material accumulation during the crushing process. This results in the material not being evenly distributed between the crushing rollers, thus affecting the crushing efficiency and effect. If the material is not evenly introduced between the crushing rollers, it will not only lead to low crushing efficiency but also cause uneven wear of the equipment, increasing energy consumption and maintenance costs. Furthermore, uneven material distribution may result in incomplete crushing in some areas, while material in other areas may be over-crushed, causing inconsistent particle sizes and affecting the subsequent application effect of the catalyst. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to provide a material crushing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A material crushing device includes a crushing box with a cavity open at the top. A sealing plate is provided on one side of the cavity opening. A vibrating frame is provided above the sealing plate. An inclined surface is provided inside the frame. Diverting plates are evenly spaced on the inclined surface. A baffle is provided above the side of the diverting plates near the feed hopper. A feed hopper is provided above the side of the frame away from the lowest point of the inclined surface. A crushing roller is provided inside the cavity near the lowest point of the inclined surface. A feed inlet is provided on the side of the frame located at the lowest point of the inclined surface. A vibrating component for driving the frame to vibrate is provided inside the cavity. A screening component is provided below the crushing roller.

[0007] Furthermore, a first spring is provided between the four corners of the frame and the sealing plate. The vibration assembly includes a rotating rod located in the cavity below the sealing plate. A first turntable is provided on both sides of the rotating rod. A plurality of first arc-shaped grooves are evenly spaced on the first turntable. Vertical connecting rods are provided on both sides of the bottom of the frame, penetrating the sealing plate and extending into the corresponding first arc-shaped grooves. A first motor for driving the rotating rod to rotate is provided on the side of the crushing box.

[0008] Furthermore, the screening assembly includes a screen frame located below the crushing roller and capable of reciprocating. The screen frame has an opening on the side away from the rotating rod, and an openable and closable baffle is provided at the opening. Slide grooves are provided on both sides of the cavity, and sliders that extend into the corresponding slide grooves are provided on both sides of the screen frame.

[0009] Furthermore, mounting blocks are provided on the two side walls near the opening of the screen frame inside the cavity. The mounting blocks have a circular cavity with one end open. A movable circular block is provided inside the circular cavity. A second spring is provided between the movable circular block and the bottom wall of the circular cavity. A cap is provided at the opening end of the circular cavity. A rod is provided on the movable circular block that extends through the cap and connects to the screen frame.

[0010] Furthermore, a second turntable is provided at the center of the rotating rod, and multiple second arc-shaped grooves are evenly spaced on the second turntable.

[0012] Furthermore, the crushing chamber is equipped with opening and closing doors on both sides.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses a vibration component to drive the frame to vibrate, which in turn causes the inclined plane to vibrate, causing the material to flow from the highest point to the lowest point of the inclined plane. As the material flows from the highest point to the lowest point, the vibration of the inclined plane, combined with the diversion plate, diverts the material, breaking up any accumulated material and distributing it evenly on the inclined plane. This allows the material to fall evenly into the crushing rollers through the feed inlet for crushing, avoiding problems such as low crushing efficiency and incomplete crushing caused by material accumulation and uneven falling into the crushing rollers.

[0015] This invention utilizes a rotating rod to drive the second turntable, causing the end of the transverse connecting rod to move back and forth between multiple second arc-shaped grooves and the sidewalls of the second turntable, thereby driving the screen frame to reciprocate. This allows for uniform feeding while simultaneously screening the pulverized material, thus improving production efficiency and product quality. Attached Figure Description

Detailed Implementation

[0021] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0022] The following is in conjunction with the appendix Figures 1-4 This embodiment will be described in further detail.

[0023] Please see Figures 1-4 This embodiment of a material crushing device includes a crushing box 100, a cavity 101 with an upper opening inside the crushing box 100, a sealing plate 102 on one side of the opening end of the cavity 101, a vibrating frame 103 above the sealing plate 102, an inclined surface 104 inside the frame 103, diverting plates 105 evenly spaced on the inclined surface 104, a baffle 106 above the side of the diverting plate 105 near the feed hopper 107, a feed hopper 107 above the side of the frame 103 away from the lowest point of the inclined surface 104, a crushing roller 108 near the lowest point of the inclined surface 104 inside the cavity 101, a feed inlet 109 on the side of the frame 103 located at the lowest point of the inclined surface 104, a vibrating assembly for driving the frame 103 to vibrate inside the cavity 101, and a screening assembly below the crushing roller 108.

[0024] In this embodiment, the sealing plate 102 is provided with a support frame for supporting the feeding hopper 107. The crushing rollers 108 are set as a group and are installed on the crushing box 100 through bearings. The end of the crushing rollers 108 is provided with meshing gears. A second motor can be installed on the side of the crushing box 100 to drive the crushing rollers 108 to rotate in order to crush the material. The crushing rollers 108 are provided with protective plates 110 on both sides that are fixedly connected to the side wall of the cavity 101.

[0025] When crushing materials, the materials are fed into the hopper 107 and fall into the inclined surface 104 inside the frame 103. The frame 103 is driven to vibrate by the vibration component, and the frame 103 drives the inclined surface 104 to vibrate, causing the materials to flow from the highest point to the lowest point of the inclined surface 104. When the materials flow from the highest point to the lowest point, the vibration of the inclined surface 104, combined with the diversion plate 105, diverts the materials, which can break up the accumulated materials and distribute them evenly on the inclined surface 104. This allows the materials to fall evenly into the crushing rollers 108 through the feed inlet 109 for crushing, avoiding problems such as low crushing efficiency and incomplete crushing caused by the accumulation of materials that cannot fall evenly into the crushing rollers 108.

[0026] In this embodiment, the baffle 106 is used to block and buffer the material, so that the material can be better diverted by the diverter 105 through vibration.

[0027] In this embodiment, the sieving component can be used to sieve the pulverized material, which can separate large particles and improve product quality.

[0028] Please see Figures 1-4 In this embodiment, a first spring 200 is provided between the four corners of the frame 103 and the sealing plate 102. The vibration component includes a rotating rod 201 located in the cavity 101 below the sealing plate 102. A first turntable 202 is provided on both sides of the rotating rod 201. A plurality of first arc-shaped grooves 203 are evenly spaced on the first turntable 202. Vertical connecting rods 204 are provided on both sides of the bottom of the frame 103, penetrating the sealing plate 102 and extending into the corresponding first arc-shaped grooves 203. A first motor 205 for driving the rotating rod 201 to rotate is provided on the side of the crushing box 100.

[0029] In this embodiment, columns are provided at the four corners of the frame 103 and the four corners of the sealing plate 102 to support the first spring 200. The rotating rod 201 is installed through bearings. The first turntable 202 is fixedly connected to the rotating rod 201. The top end of the vertical connecting rod 204 is fixedly connected to the frame 103. The vertical connecting rod 204 and the sealing plate 102 are slidably connected. The bottom of the vertical connecting rod 204 is arc-shaped to facilitate sliding. The rotating rod 201 is driven to rotate by the first motor 205. The rotating rod 201 drives the first turntable 202 to rotate, so that the bottom of the vertical connecting rod 204 can move back and forth between the multiple first arc-shaped grooves 203 and the side wall of the first turntable 202, thereby causing the vertical connecting rod 204 to move up and down. At the same time, in conjunction with the action of the first spring 200, the frame 103 is driven to vibrate.

[0030] Please see Figures 1-4 In this embodiment, the screening assembly includes a screen frame 300 located below the crushing roller 108 and capable of reciprocating. The screen frame 300 has an opening on the side away from the rotating rod 201, and a gate 301 that can be opened and closed is provided at the opening. Slide grooves 302 are provided on both sides of the cavity 101, and sliders 303 extending into the corresponding slide grooves 302 are provided on both sides of the screen frame 300.

[0031] In this embodiment, vertical slots can be provided on both sides of the opening, and the baffle 301 can be pulled out through the vertical slots to control the opening and closing of the opening. Insertion holes can be provided on the upper ends of both sides of the baffle 301, and spring pins can be provided on the corresponding insertion holes on the walls of the screen frame 300 on both sides of the opening to limit the baffle 301 and prevent the baffle 301 from opening during operation. When cleaning the material in the screen frame 300, the baffle 301 can be opened and the material in the screen frame 300 can be taken out through the opening. The slider 303 is fixedly connected to the screen frame 300. The slider 303 extends into the slide groove 302 to support the screen frame 300. The slider 303 is slidably connected to the slide groove 302. By the reciprocating movement of the slider 303 in the slide groove 302, the screen frame 300 reciprocates, thereby screening the material in the screen frame 300.

[0032] Please see Figures 1-4 In this embodiment, mounting blocks 304 are provided on the two side walls of the cavity 101 near the opening of the screen frame 300. Each mounting block 304 has a circular cavity with one open end. A movable circular block 305 is provided within the circular cavity.

Multiple second arc-shaped grooves 401 are evenly spaced on the second turntable 400. A transverse connecting rod 402 extending into the second arc-shaped groove 401 is provided on the side of the screen frame 300 near the second turntable 400.

[0033] In this embodiment, the mounting block 304 is fixedly connected to the side wall of the cavity 101, the movable circular block 305 is slidably connected within the cavity, and the cap 307 is threadedly connected to the open end of the cavity for mounting the components within the cavity. The rod 308 is fixedly connected to the movable circular block 305, the second turntable 400 is fixedly connected to the rotating rod 201, and the transverse connecting rod 402 is fixedly connected to the screen frame 300. The end of the transverse connecting rod 402 extending into the second arc-shaped groove 401 is arc-shaped to facilitate sliding. By rotating the rod 201, the second turntable 400 is rotated, causing the end of the transverse connecting rod 402 to move back and forth between the multiple second arc-shaped grooves 401 and the side wall of the second turntable 400, thereby driving the screen frame 300 to reciprocate. This allows for uniform feeding while simultaneously screening the pulverized material, thereby improving production efficiency and product quality.

[0034] Please see Figures 1-4 In this embodiment, the cavity 101 is provided with a receiving box 500 located below the sieve frame 300, and the side of the crushing box 100 is provided with a slot for the receiving box 500 to be pulled out.

[0035] In this embodiment, the receiving box 500 is used to collect the screened material. A slide rail can be provided inside the cavity 101, and the receiving box 500 can slide through the slide rail so that the receiving box 500 can be pulled out through the slot to take out the material.

[0036] Please see Figures 1-4 In this embodiment, the crushing box 100 is provided with opening and closing doors 501 on both sides.

[0037] In this embodiment, the opening and closing door 501 is hinged to both sides of the crushing box 100. The opening and closing door 501 facilitates the maintenance and upkeep of the components inside the cavity 101 by the staff.

[0038] In this embodiment, when cleaning the material inside the screen frame 300, the opening and closing door 501 can be opened first, and then the blocking door 301 can be opened to clean and collect the material inside the screen frame 300.

[0039] In use, the material is fed into the hopper 107 and falls into the inclined surface 104 inside the frame 103. Driven by the first motor 205, the frame 103 vibrates, and the frame 103 drives the inclined surface 104 to vibrate, causing the material to flow from the highest point to the lowest point of the inclined surface 104. When the material flows from the highest point to the lowest point, the vibration of the inclined surface 104, combined with the diversion plate 105, diverts the material, which can break up the accumulated material and distribute it evenly on the inclined surface 104, so that the material falls evenly into the crushing rollers 108 through the feed inlet 109 for crushing.

[0040] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
