Description

Technical Field

[0001] This application belongs to the technical field of biomass additive processing equipment, specifically relating to an anti-clogging integrated particle screening and cooling device. Background Technology

[0002] Biomass refers to organisms formed through photosynthesis, including plants, animals, and microorganisms, as well as their metabolic products and waste. Because biomass raw materials are complex, including lignin, cellulose, and other organic matter, non-biomass materials, such as large particles of soil or plastics, are removed to improve biomass utilization efficiency. This increases the purity of the biomass, reduces wear on equipment caused by impurities, and facilitates further processing and treatment.

[0003] Existing biomass screening devices typically employ multi-stage inclined screening plates, with adjacent upper and lower screening plates tilted at opposite angles. The purpose is to allow material from the upper layers to slide down the inclined plates, passing through multiple stages of screening. However, this arrangement, where the inclined upper and lower screening plates transfer material through corner areas, is prone to congestion at these corners when there is a large amount of material. Furthermore, the material tends to concentrate and slide downwards under its own weight, causing accumulation at the corners. This congestion hinders further screening and prevents the material from being dispersed. Especially with materials containing moisture, the material concentrated at the corners tends to stick together, slowing down screening and reducing efficiency. It also increases the risk of unscreened material re-agglomerating, further reducing screening effectiveness. Utility Model Content

[0004] This application provides an anti-clogging particle screening and cooling integrated device to solve the problems that the inclined screening plate is prone to clogging at the corners, and that the inclined screening plate makes the material tend to fall downwards under its own weight, which aggravates the clogging and causes the subsequent material screening to be slow; it also makes it easy for wet materials to stick together or clump together, resulting in a decrease in screening effect.

[0005] The technical solution adopted in this application is as follows: An anti-clogging integrated particle screening and cooling device includes: The shell has a feed inlet at the top, and the feed inlet is connected to a hopper; A screening mechanism is connected inside the housing; the screening mechanism includes a first screening component placed horizontally and a second screening component disposed below the first screening component; The first screening component includes a first driving member and a first screening plate; the first driving member is connected to one side of the first screening plate and is used to drive the first screening plate to slide back and forth in a straight line; the first screening plate has a plurality of first screening holes, so that the material falls into the second screening component through the first screening holes; The second screening component includes a vibrating cylinder and a second screening plate; the vibrating cylinder is connected to the bottom of the second screening plate, and the second screening plate has multiple second screening holes. When the material falls into the second screening plate, the vibrating cylinder drives the second screening plate to vibrate, so that the material is screened through the second screening holes.

[0006] This application achieves multi-stage screening and finer material separation by incorporating at least two screening components within the housing. Material passes through a first screening component and then a second screening component for further screening. The first driving component of the first screening component drives a first screening plate to reciprocate linearly, repeatedly shaking the material on the plate and enhancing the screening force. This allows the material to be fully separated and fall through multiple first screening holes into the second screening component for further thorough screening. The second screening component is connected to a second screening plate via a vibrating cylinder, which drives the plate to vibrate, further strengthening the shaking force on the material and improving screening efficiency. The material moves relative to each other under the vibration of the second screening plate and then falls through the second screening holes under its own weight for further screening. This application avoids the limitations of traditional inclined screening methods. During material transfer between the upper and lower screening plates, the material is transferred through the right or left corner areas. Furthermore, the material tends to accumulate under its own weight, leading to congestion in these corner areas and hindering the dispersed material flow. Additionally, some materials have moisture content, and concentrated discharge can cause unscreened material to clump together again, reducing screening efficiency. This application addresses this by placing the first and second screening plates horizontally. The first screening plate moves back and forth in a straight line for screening, while the second screening plate vibrates and shakes for further screening. This allows for autonomous screening at each stage, enabling the material on the screening plates to disperse and move freely, separating and falling under its own weight. This results in more thorough screening and improved screening efficiency.

[0007] In a preferred embodiment, a first positioning platform is connected inside the housing. The first positioning platform is located below the first screening plate. The middle part of the first positioning platform has a hollow structure, forming a clearance space for multiple first screening holes. A slide rail is connected to the top of the first positioning platform, and a slider is connected to the bottom of the first screening plate. The first screening plate moves along the slide rail by the cooperation of the slider and the slide rail.

[0008] This application provides a first positioning platform inside the housing, which is connected to both sides of the first screening plate. The purpose of the first positioning platform is to support the first screening plate, allowing it to carry more material, and to enable the first screening plate to move back and forth linearly along the first positioning platform. In addition, the first positioning platform is distributed on both sides of the first screening plate, so the middle of the first positioning platform is hollow, forming a clearance space under the multiple first screening holes of the first screening plate, thus preventing the material in the first screening holes of the first screening plate from falling into the second screening component.

[0009] In a preferred embodiment, the first screening assembly further includes a first receiving trough, which is connected to one side of the first screening plate.

[0010] This application sets a first receiving trough connected to one side of the first screening plate. The purpose is that when the size of the material on the first screening plate is larger than the first screening hole of the first screening plate and cannot fall down into the second screening component, it can move along the first receiving trough on one side of the first screening plate under the action of the first brush rod, as described below. This allows the material to be transferred to the first receiving trough for collection and recycling, thereby saving energy and facilitating the subsequent screening of materials, preventing material from clogging the first screening hole.

[0011] In a preferred embodiment, the first screening component further includes a first unblocking component; the first unblocking component includes a first driving device and a first brush rod, the first brush rod being disposed above the first screening plate and capable of moving along the width direction of the first screening plate under the drive of the first driving device, so as to collect the material on the first screening plate that has not passed through the first screening hole into the first receiving trough.

[0012] This application provides a first unblocking component, in which a first driving device drives a first brush rod to move along the width of the first screening plate. This allows excess material on the first screening plate to be transported to the first receiving trough under the driving action of the first brush rod, collecting the excess material to avoid occupying the space of the first screening plate. This facilitates subsequent material screening and prevents material from clogging the first screening plate.

[0013] In a preferred embodiment, the first driving device includes a drive motor, a lead screw, and a sliding block; the drive motor is connected to the outside of the housing, one end of the lead screw is connected to the drive motor, and the other end of the lead screw extends into the housing along the width direction of the housing; the sliding block is connected to the outside of the lead screw; and the first brush rod is connected to the sliding block.

[0014] The drive motor of the first drive device of this application is connected to the outside of the housing and can drive the lead screw located inside the housing to rotate. A sliding block is threadedly connected to the outside of the lead screw. When the lead screw rotates, the sliding block can move along the axis of the lead screw. Since the sliding block is connected to the first brush rod, the first brush rod includes a first connecting rod and a first brush. The first brush is connected to the outside of the first connecting rod. Because the periphery of the first screening plate has a first retaining edge, in order to enable the first brush to contact the top surface of the first filter plate and the other end of the first connecting rod to be connected to the sliding block, the first connecting rod is designed in a Z-shaped structure. That is, the first connecting rod has a first low section, a first high section and a second low section that are connected in sequence to form an integrated structure. The first low section is connected to the first brush and the second low section is connected to the sliding block. When the first drive device is not activated, the first brush rod is located on the side of the first screening plate away from the first receiving trough, corresponding to the top of the first positioning platform. The initial area of ​​the first screening plate where the first brush rod is located in the initial state does not have the first screening hole, so it will not affect the screening of the material. After the material screening is completed, the first drive device is activated to make the first brush rod move towards the first receiving trough along the width direction of the first screening plate, so that the excess material in the first receiving trough falls from the first screening hole.

[0015] In a preferred embodiment, the second screening assembly further includes a plurality of buffer assemblies; the plurality of buffer assemblies are connected to the bottom periphery of the second screening plate; the buffer assembly includes a second positioning platform, a support column, and a spring; the support column is connected above the second positioning platform, the spring is connected above the support column, and the top of the spring is connected to the second screening plate.

[0016] The purpose of this application in setting up a buffer assembly is to enable automatic reset under the action of a spring when the vibrating cylinder drives the second screening plate to vibrate. The spring can be a nitrogen spring, which plays a role in resetting the second screening plate. Moreover, the spring is an elastic element that can buffer the vibration of the vibrating cylinder on the second screening plate. This allows the second screening plate to fully vibrate and screen the material, while also increasing the protection of the second screening plate and preventing the material from being shaken off due to violent vibration. The buffer assembly has a second positioning platform connected to the housing, which also supports the second screening plate, thereby further strengthening the protection of the second screening plate, improving the material carrying capacity, and increasing the overall service life of the device.

[0017] In a preferred embodiment, the inner diameter of the second screening hole is smaller than the inner diameter of the first screening hole.

[0018] The purpose of the second screening hole being smaller than the first screening hole in this application is to allow larger materials to be screened first, followed by smaller materials to be screened step by step, ultimately obtaining materials of the required size. This facilitates precise screening of materials at each stage, thereby refining the screening process and achieving thorough screening of materials.

[0019] As a preferred embodiment, the anti-clogging particle screening and cooling integrated device of this application further includes a third screening component; the third screening component includes a second driving member and a third screening plate; the second driving member is connected to one side of the third screening plate and is used to drive the third screening plate to slide back and forth in a straight line; the third screening plate has a plurality of third screening holes, so that the material falls through the third screening holes.

[0020] This application enhances the screening of materials by setting a third screening component. The third screening component has the same structure as the first screening component, thereby increasing the screening steps and process, further improving the screening fineness of the materials, ensuring that the materials can be fully screened, reducing material leakage and improving screening quality, and achieving uniform screening of materials.

[0021] In a preferred embodiment, a guide component is also connected above the third screening component; the guide component includes a first guide plate and a second guide plate connected to both sides of the housing; the bottom of the first guide plate and the second guide plate are inclined inward to form a funnel-shaped opening, so that the material falling from the second screening hole can fall onto the third screening plate through the opening along the first guide plate and the second guide plate.

[0022] This application connects a guide component between the second and third screening components to prevent material from not falling completely from the second screening plate into the third screening plate during the vibration of the second screening plate. Therefore, a guide component is added between the second and third screening components. The guide component includes a first guide plate and a second guide plate that are inclined to form a funnel-shaped structure, so that the lower opening size of the first and second guide plates is smaller than the upper opening size. This facilitates the material to slide from inside the second screening plate along the first and second guide plates into the third screening plate, thereby preventing the material from scattering in all directions and ensuring that the material can be fully conveyed into the third screening plate. It can also further guide the material to move in a dispersed manner into the third screening plate and prevent the material from sticking together.

[0023] In a preferred embodiment, a receiving plate is also provided below the third screening component. The receiving plate is inclinedly connected to the housing, and one side of the receiving plate extends to the discharge port of the housing. A receiving box is connected to the outside of the discharge port of the housing. The material slides down the receiving plate to the discharge port and is collected in the receiving box.

[0024] This application provides an inclined receiving plate below the third screening plate. The receiving plate is inclined downward toward the discharge port of the shell, and one end of the receiving plate can extend into the discharge port. This allows the material to be dispersed and conveyed downward along the receiving plate to the discharge port when it falls from the third screening plate. This can guide the material to fully enter the discharge port, prevent material leakage, prevent material sticking, and ensure that the material is evenly conveyed to the discharge port.

[0025] In a preferred embodiment, a heat exchange assembly is connected to the inner circumferential side of the shell, and the heat exchange assembly includes heat exchange tubes that meander from top to bottom.

[0026] In this application, a heat exchange component is connected to the inner wall of the shell. The heat exchange component adopts a meandering heat exchange tube, which can be distributed around the shell and evenly arranged from top to bottom, thereby achieving sufficient heat exchange with the material, further reducing the internal temperature of the shell, and achieving cooling of the material inside the shell. Moreover, this application uses heat exchange tubes instead of traditional fans to blow on the material, which can avoid the problem of material being blown up and diffused inside the shell, resulting in insufficient screening of the material. The structure of the heat exchange tubes in this application can replace the cooling medium in the heat exchange tubes in a timely manner, and can also effectively ensure that the temperature of the shell remains constant, achieving sufficient cooling of the material.

[0027] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows: 1. This application relates to an anti-clogging integrated particle screening and cooling device, comprising a first screening component placed horizontally and a second screening component disposed below the first screening component; the first screening component includes a first driving member and a first screening plate; the first driving member is connected to one side of the first screening plate and is used to drive the first screening plate to slide back and forth in a straight line; the first screening plate has a plurality of first screening holes, so that the material falls into the second screening component through the first screening holes; the second screening component includes a vibrating cylinder and a second screening plate; the vibrating cylinder is connected to the bottom of the second screening plate, the second screening plate has a plurality of second screening holes, and when the material falls into the second screening plate, the vibrating cylinder drives the second screening plate to vibrate, so that the material is screened through the second screening holes.

[0028] In traditional inclined upper and lower screening plates, material is transferred between them via the right or left corner areas. Furthermore, the material tends to accumulate under its own weight, leading to congestion in these corner areas when there is a large amount of material. This prevents the material from being discharged in a dispersed manner. Additionally, some materials have a certain level of moisture, and concentrated discharge can cause unscreened material to clump together again, resulting in a decrease in screening efficiency. This application employs a first screening component and a second screening component arranged horizontally. The first screening component can move back and forth in a straight line in the horizontal direction, while the second screening component can vibrate irregularly within its own area. This allows the material to move separately within the first and second screening components, thus conveying the dispersed material. This prevents the material from concentrating and moving from the upper layer to the lower layer, which could easily accumulate at the corner between the inclined upper and lower layers. Instead, the material can be dispersed and screened separately, and the drying of wet material can be accelerated. Due to the mutual movement between the materials, the phenomenon of material clumping can be avoided.

[0029] The first driving component of the first screening assembly of this application can drive the first screening plate to reciprocate along a straight line, causing the material on the first screening plate to be repeatedly shaken back and forth, further enhancing the screening force of the material, so that the material can be fully separated and fall into the second screening assembly through multiple first screening holes, further achieving thorough screening; the second screening assembly is connected to the second screening plate through a vibrating cylinder, and the vibrating cylinder drives the second screening plate to vibrate, further enhancing the shaking force of the material on the second screening plate, thereby improving the screening of the material by the second screening plate, so that... Under the vibration of the second screening plate, the material can move relative to each other and then fall through the second screening hole under its own weight for further screening. In this application, the first screening plate and the second screening plate are placed horizontally. The first screening plate can move back and forth in a straight line to achieve screening, and the second screening plate can vibrate and shake to achieve screening. This realizes autonomous screening of each screening component, so that the material on the screening plate can be fully dispersed and move relative to each other, be fully separated, and fall with the aid of its own weight, thereby making the material screening more thorough and improving the screening effect.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0035] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0036] This application relates to an anti-clogging integrated particle screening and cooling device, such as... Figure 1-3 As shown, it includes: The shell 1 has a feed inlet at the top, and the feed inlet is connected to a hopper 2; A screening mechanism is connected inside the housing 1; the screening mechanism includes a first screening component 3 placed horizontally and a second screening component 4 disposed below the second screening component 4; The first screening component 3 includes a first driving member 31 and a first screening plate 32; the first driving member 31 is connected to one side of the first screening plate 32 and is used to drive the first screening plate 32 to slide back and forth in a straight line; the first screening plate 32 has a plurality of first screening holes 7, so that the material falls into the second screening component 4 through the first screening holes 7. The second screening component 4 includes a vibrating cylinder 41 and a second screening plate 42. The vibrating cylinder 41 is connected to the bottom of the second screening plate 42. The second screening plate 42 has multiple second screening holes. When the material falls into the second screening plate 42, the vibrating cylinder 41 drives the second screening plate 42 to vibrate, so that the material is screened through the second screening holes.

[0037] In traditional inclined upper and lower screening plates, material is transferred between them via the right or left corner areas. Furthermore, the material tends to accumulate under its own weight, leading to congestion in these corner areas when there is a large amount of material. This prevents the material from being discharged in a dispersed manner. Additionally, some materials have a certain level of moisture, and concentrated discharge can cause unscreened material to clump together again, resulting in a decrease in screening efficiency. This application employs a first screening component 3 and a second screening component 4 arranged horizontally. The first screening component 3 can move back and forth in a straight line in the horizontal direction, while the second screening component 4 can vibrate irregularly within its own area. This allows the material to move separately within the first screening component 3 and the second screening component 4, thus conveying the dispersed material. This prevents the material from concentrating and moving from the upper layer to the lower layer, which could easily accumulate at the corner between the inclined upper and lower layers. Instead, the material can be dispersed and screened separately, and the drying of wet material can be accelerated. Due to the mutual movement between the materials, the phenomenon of material clumping can be avoided.

[0038] This application achieves multi-stage screening of materials by setting at least two screening components inside the housing 1. Materials pass through the first screening component 3 and then the second screening component 4 for further screening, thus achieving finer screening. The first driving component 31 of the first screening component 3 drives the first screening plate 32 to reciprocate in a straight line, causing the materials on the first screening plate 32 to be repeatedly shaken, further strengthening the screening force and enabling the materials to be fully separated and fall into the second screening component 4 through multiple first screening holes 7, achieving further thorough screening. The second screening component 4 is connected to the second screening plate 42 via a vibrating cylinder 41, which drives the second screening plate 42 to vibrate. This further enhances the shaking force on the material on the second screening plate 42, thereby improving the screening effect of the second screening plate 42. The material can move relative to each other under the vibration of the second screening plate 42, and then fall through the second screening holes under its own weight for further screening. Furthermore, this application places the first screening plate 32 and the second screening plate 42 horizontally. The first screening plate 32 can move back and forth in a straight line to achieve screening, while the second screening plate 42 can vibrate and shake to achieve screening. This achieves autonomous screening for each screening component, allowing the material on the screening plate to be fully dispersed and move relative to each other, fully separated, and falling under its own weight, thus making the screening more thorough and improving the screening effect.

[0039] In a preferred embodiment, a first positioning platform 6 is connected inside the housing 1. The first positioning platform 6 is located below the first screening plate 32. The middle part of the first positioning platform 6 has a hollow structure, forming a clearance space for multiple first screening holes 7. A slide rail 13 is connected to the top of the first positioning platform 6, and a slider is connected to the bottom of the first screening plate 32. The first screening plate 32 moves along the slide rail 13 by the cooperation of the slider and the slide rail 13.

[0040] This application provides a first positioning platform 6 inside the housing 1, which is connected to both sides of the first screening plate 32. The purpose of the first positioning platform 6 is to support the first screening plate 32 so that it can carry more material, and also to allow the first screening plate 32 to move back and forth linearly along the first positioning platform 6. In addition, the first positioning platform 6 is distributed on both sides of the first screening plate 32, so the middle of the first positioning platform 6 is hollow, forming a clearance space under the multiple first screening holes 7 of the first screening plate 32, so as to prevent the material in the first screening holes 7 of the first screening plate 32 from falling into the second screening component 4.

[0041] In a preferred embodiment, the first screening component 3 further includes a first receiving trough 33, which is connected to one side of the first screening plate 32.

[0042] This application sets a first receiving trough 33 connected to one side of the first screening plate 32. The purpose is that when the size of the material on the first screening plate 32 is larger than the first screening hole 7 of the first screening plate 32 and cannot fall down into the second screening component 4, it can move along the first receiving trough 33 on one side of the first screening plate 32 under the action of the first brush rod 342. This allows the material to be transferred into the first receiving trough 33 for collection and recycling, thereby saving energy and facilitating the subsequent screening of materials, and preventing the material from clogging the first screening hole 7.

[0043] In a preferred embodiment, the first screening component 3 further includes a first unblocking component 34; the first unblocking component 34 includes a first driving device 341 and a first brush rod 342. The first brush rod 342 is disposed above the first screening plate 32 and can move along the width direction of the first screening plate 32 under the drive of the first driving device 341, so as to collect the material on the first screening plate 32 that has not passed through the first screening hole 7 into the first receiving trough 33.

[0044] This application provides a first unblocking component 34. The first driving device 341 of the first unblocking component 34 can drive the first brush rod 342 to move along the width direction of the first screening plate 32, so that the excess material on the first screening plate 32 can be transported to the first receiving trough 33 under the driving action of the first brush rod 342, so as to collect the excess material, so as not to occupy the space of the first screening plate 32, which is conducive to the subsequent screening of materials and prevents the material from blocking the first screening plate 32.

[0045] In a preferred embodiment, the first driving device 341 includes a drive motor 3411, a lead screw 3412, and a sliding block 3413; the drive motor 3411 is connected to the outside of the housing 1, one end of the lead screw 3412 is connected to the drive motor 3411, and the other end of the lead screw 3412 extends into the inside of the housing 1 along the width direction of the housing 1; the sliding block 3413 is connected to the outside of the lead screw 3412; and the first brush rod 342 is connected to the sliding block 3413.

[0046] The drive motor 3411 of the first drive device 341 of this application is connected to the outside of the housing 1 and can drive the lead screw 3412 located inside the housing 1 to rotate. A sliding block 3413 is threadedly connected to the outside of the lead screw 3412. When the lead screw 3412 rotates, the sliding block 3413 can move along the axis of the lead screw 3412. Since the sliding block 3413 is connected to the first brush rod 342, the first brush rod 342 includes a first connecting rod 3421 and a first brush 3422. The first brush 3422 is connected to the first connecting rod 3421. The outer side of the connecting rod 3421; because the periphery of the first screening plate 32 has a first retaining edge, in order to enable the first brush 3422 to contact the top surface of the first filter plate, and the other end of the first connecting rod 3421 to be connected to the sliding block 3413, the first connecting rod 3421 is designed in a Z-shape structure, that is, the first connecting rod 3421 has a first low section, a first high section and a second low section connected in sequence to form an integrated structure, the first low section is connected to the first brush 3422, and the second low section is connected to the sliding block 3413. When the first drive device 341 is not activated, the first brush rod 342 is located on the side of the first screening plate 32 away from the first receiving trough 33, corresponding to the top of the first positioning platform 6. The initial area of ​​the first screening plate 32 where the first brush rod 342 is located in the initial state does not have the first screening hole 7, so it will not affect the screening of materials. After the material screening is completed, the first drive device 341 is activated to make the first brush rod 342 move towards the first receiving trough 33 along the width direction of the first screening plate 32, so that the excess material in the first receiving trough 33 falls from the first screening hole 7.

[0047] In a preferred embodiment, the second screening component 4 further includes a plurality of buffer components 43; the plurality of buffer components 43 are connected to the bottom periphery of the second screening plate 42; the buffer component 43 includes a second positioning platform 8, a support column and a spring; the support column is connected above the second positioning platform 8, the spring is connected above the support column, and the top of the spring is connected to the second screening plate 42.

[0048] The purpose of this application in setting up the buffer assembly 43 is to enable automatic reset under the action of a spring when the vibrating cylinder 41 drives the second screening plate 42 to vibrate. The spring can be a nitrogen spring, which plays a role in resetting the second screening plate 42. Moreover, the spring is an elastic element that can buffer the vibration effect of the vibrating cylinder 41 on the second screening plate 42. This allows the second screening plate 42 to not only fully vibrate and screen the material, but also increases the protection of the second screening plate 42, preventing the material from being shaken off easily due to violent vibration. The buffer assembly 43 has a second positioning platform 8 connected to the housing 1, which can also support the second screening plate 42, thereby further strengthening the protection of the second screening plate 42, improving the material carrying capacity, and increasing the overall service life of the device.

[0049] In a preferred embodiment, the inner diameter of the second screening hole is smaller than the inner diameter of the first screening hole 7.

[0050] The purpose of the second screening hole being smaller than the first screening hole 7 is to allow larger materials to be screened first, followed by smaller materials to be screened step by step, ultimately obtaining materials of the required size. This facilitates precise screening of materials at each stage, thereby refining the screening process and achieving thorough screening of materials.

[0051] As a preferred embodiment, the anti-clogging particle screening and cooling integrated device of this application further includes a third screening component 5; the third screening component 5 includes a second driving member 51 and a third screening plate 52; the second driving member 51 is connected to one side of the third screening plate 52 and is used to drive the third screening plate 52 to slide back and forth in a straight line; the third screening plate 52 has a plurality of third screening holes, so that the material falls through the third screening holes.

[0052] This application further enhances the screening of materials by setting a third screening component 5. The third screening component 5 has the same structure as the first screening component 3, thereby increasing the screening steps and processes for materials, further improving the screening fineness of materials, ensuring that materials can be fully screened, reducing material leakage and improving screening quality, and achieving uniform screening of materials.

[0053] Furthermore, a third positioning platform is connected inside the housing 1. The third positioning platform is located below the third screening plate 52. The middle part of the third positioning platform has a hollow structure, forming a clearance space for multiple third screening holes. A slide is connected to the top of the third positioning platform, and a slide block is connected to the bottom of the third screening plate 52. The third screening plate 52 moves along the slide by the cooperation of the slide block and the slide.

[0054] In addition, the third screening component 5 may also include a second receiving trough, which is connected to one side of the third screening plate 52; the second unblocking component includes a second driving device and a second brush rod, which is disposed above the third screening plate 52 and can move along the width direction of the third screening plate 52 under the drive of the second driving device, so as to collect the material on the third screening plate 52 that has not passed through the third screening hole into the second receiving trough.

[0055] Furthermore, the first drive device 341 includes a motor, a connecting screw 3412, and a connecting block; the motor is connected to the outside of the housing 1, one end of the connecting screw 3412 is connected to the motor, and the other end of the connecting screw 3412 extends into the inside of the housing 1 and extends along the width direction of the housing 1; the connecting block is threaded to the outside of the connecting screw 3412; and the second brush rod is connected to the connecting block.

[0056] In a preferred embodiment, a guide component 9 is also connected above the third screening component 5; the guide component 9 includes a first guide plate 91 and a second guide plate 92 connected to both sides of the housing 1; the bottom of the first guide plate 91 and the second guide plate 92 are inclined inward to form a funnel-shaped opening, so that the material falling from the second screening hole can fall onto the third screening plate 52 through the opening along the first guide plate 91 and the second guide plate 92.

[0057] This application connects a guide component 9 between the second screening component 4 and the third screening component 5. The purpose is to prevent material from not falling completely from the second screening plate 42 into the third screening plate 52 during the vibration of the second screening plate 42. Therefore, a guide component 9 is added between the second screening component 4 and the third screening component 5. The guide component 9 includes a first guide plate 91 and a second guide plate 92 that are inclined. The first guide plate 91 and the second guide plate 92 are inclined to form a funnel-shaped structure, so that the lower opening size of the first guide plate 91 and the second guide plate 92 is smaller than the upper opening size. This facilitates the material to slide from inside the second screening plate 42 along the first guide plate 91 and the second guide plate 92 into the third screening plate 52, thereby preventing the material from scattering in all directions and ensuring that the material can be fully conveyed into the third screening plate 52. It can also further guide the material to move dispersedly into the third screening plate 52 and prevent the material from sticking together.

[0058] In a preferred embodiment, a receiving plate 11 is also provided below the third screening component 5. The receiving plate 11 is inclinedly connected to the housing 1, and one side of the receiving plate 11 extends to the discharge port of the housing 1. A receiving box 12 is connected to the outside of the discharge port of the housing 1. The material slides down through the receiving plate 11 to the discharge port and is collected in the receiving box 12.

[0059] This application provides an inclined receiving plate 11 below the third screening plate 52. The receiving plate 11 is inclined downward toward the discharge port of the housing 1, and one end of the receiving plate 11 can extend into the discharge port. This allows the material to be dispersed and conveyed downward along the receiving plate 11 into the discharge port when it falls from the third screening plate 52. This can guide the material to fully enter the discharge port, prevent material leakage, prevent material adhesion, and ensure that the material is evenly conveyed into the discharge port.

[0060] In a preferred embodiment, a heat exchange assembly is connected to the inner wall periphery of the housing 1, and the heat exchange assembly includes a heat exchange tube 10 that is meandering from top to bottom.

[0061] The shell 1 is also provided with a water inlet and a water outlet. The water inlet is connected to the water outlet end of the heat exchange tube 10. The multiple heat exchange tubes 10 connected to the periphery can be interconnected and can also be connected to the water inlet through a first branch pipe and to the water outlet through a second branch pipe. A water pump is also connected to one side of the water inlet, so that the external cooling medium is connected to the water inlet through the water pump and the main pipe. The cooling medium is connected to the multiple heat exchange tubes 10 on the periphery of the shell 1 through the water inlet and the first branch pipe. Then the cooling medium is output to the water outlet through the outlet of the multiple heat exchange tubes 10 and the second branch pipe for collection.

[0062] In this application, a heat exchange assembly is connected to the inner wall of the shell 1. The heat exchange assembly adopts a meandering heat exchange tube 10. The heat exchange tube 10 can be distributed around the shell 1 and evenly arranged from top to bottom, thereby achieving sufficient heat exchange with the material, further reducing the internal temperature of the shell 1, and achieving cooling of the material inside the shell 1. Moreover, this application uses heat exchange tubes 10 instead of using a traditional fan to blow on the material, which can avoid the problem of the material being blown up and diffused inside the shell 1 due to the traditional fan, resulting in insufficient screening of the material. The structure of the heat exchange tube 10 in this application can replace the cooling medium in the heat exchange tube 10 in a timely manner, and can also effectively ensure that the temperature of the shell 1 remains constant, achieving sufficient cooling of the material.
