Description

Technical Field

[0001] This invention relates to the technical field of adsorbent granulation, and more specifically to an adsorbent granulation apparatus. Background Technology

[0002] Bentonite adsorbent material is a functional material with adsorption characteristics such as large specific surface area and cation exchange capacity, which is made from bentonite, with montmorillonite as the main component, through purification, modification and other processes. It belongs to an important category of non-metallic mineral-based adsorbents. If granular bentonite adsorbent material, bentonite filter media, bentonite balls and other molded products are to be prepared, a granulator is required in the manufacturing process to achieve shaping and granulation.

[0003] Patent document CN221182667U discloses a chemical granulation device, including a granulation cylinder and an extrusion plate. A motor is fixed to one side of the granulation cylinder, and one end of a rotating shaft is fixed to the motor shaft. A threaded rod is fixed to the other end of the rotating shaft. A spiral pusher is provided on the outer wall of the rotating shaft. Slide grooves are respectively opened at both ends of the extrusion plate. One end of a spring is fixed to one side of the slide groove, and a locking block is fixed to the other end of the spring. The locking block is slidably connected to the slide groove. By setting up the extrusion plate, granulation holes, pressing blocks, connecting rods, locking blocks, springs, slots, and grooves, the extrusion plate can be disassembled and replaced. Extrusion plates with different granulation hole diameters can be replaced according to usage needs. By setting up the rotating shaft, threaded rod, mounting sleeve, and threaded groove, the mounting sleeve and cutting blade can be installed to realize the processing of particles of different sizes.

[0004] However, this solution still has the following problems. The existing technology uses a screw conveyor to push bentonite raw materials. The screw conveyor mainly includes a screw plate, which rotates to transport the bentonite raw materials to the granulation holes for forming. However, prolonged use, unsuitable moisture and particle size of the bentonite raw materials, uneven feeding speed, or excessive feeding may all lead to blockage of the granulation holes. Once the granulation holes are blocked to a certain extent, the granulation efficiency is affected. In addition, if the screw conveyor continues to work, it will cause machine overload and excessive compression of the bentonite raw materials at the granulation holes, affecting the processing quality of the finished product. Summary of the Invention

[0005] This invention provides an adsorbent granulation device, which aims to solve the problem in related technologies that the granulation holes are easily blocked, causing excessive compression of bentonite raw materials and equipment overload.

[0006] The adsorbent granulation device of the present invention includes a base and a feeding chamber opened in the base. An extrusion plate is arranged in the feeding chamber. The base is provided with a feeding assembly, a cleaning assembly and a control assembly. The feeding assembly includes: a central rod rotatably assembled in the feeding chamber, a spiral plate arranged outside the central rod, and a driving component arranged on the base. The central rod is connected to the cleaning assembly. The control assembly includes: a first sleeve connected to the output shaft of the driving component, a second sleeve connected to the central rod, a first spring and a sensing component arranged between the first and second sleeves. The first spring connects the first and second sleeves. When the extrusion plate is blocked, the second sleeve rotates relative to the first sleeve. The sensing component is used to detect the rotation angle of the second sleeve relative to the first sleeve. After the second sleeve rotates relative to the first sleeve to a certain angle, the driving component drives the central rod to rotate in the opposite direction to reverse the conveying of bentonite raw material. At the same time, the cleaning assembly cleans the extrusion plate.

[0007] The effect is that after the bentonite raw material is added into the pushing chamber, the pushing component drives the bentonite raw material to the extrusion plate, where it is extruded and shaped. Specifically, the drive unit drives the intermediate rod to rotate through connecting sleeve one and connecting sleeve two. The intermediate rod drives the spiral plate to rotate and transport the bentonite raw material. When the extrusion plate is blocked, the resistance of the spiral plate increases, and connecting sleeve two rotates relative to connecting sleeve one. At the same time, the sensing component detects the rotation angle of connecting sleeve two relative to connecting sleeve one. When the extrusion plate is blocked to a certain extent, that is, when connecting sleeve two rotates to a certain angle relative to connecting sleeve one, the sensing component controls the drive unit to reverse the spiral plate. The spiral plate rotates in reverse, and the cleaning component cleans the extrusion plate. By reversing the spiral plate after the extrusion plate is blocked to a certain extent, the phenomenon of excessive extrusion of bentonite raw material by the spiral plate and equipment overload is reduced.

[0008] Preferably, the sensing element includes a sensing plate and a pressure sensor disposed on the side of the sensing plate. A controller is disposed on the base. The sensing plate is axially slidingly engaged with the connecting sleeve. A locking block is disposed on the side of the sensing plate. A threaded groove is formed on the inner wall of the connecting sleeve. The locking block is slidably engaged with the threaded groove. Different positions in the threaded groove engage with the locking block to drive the sensing plate to slide relative to the connecting sleeve. The movement of the sensing plate causes the pressure sensor to abut against the base. The pressure sensor is electrically connected to the controller. The controller is electrically connected to the drive component. After the pressure sensor abuts against the base, the controller controls the drive component to drive the intermediate rod to rotate in the opposite direction.

[0009] Its effect is that the second sleeve rotates relative to the first sleeve, and the different positions of the first locking block and the first threaded groove engage, causing the sensing plate to slide relative to the first sleeve. At the same time, the sensing plate causes the pressure sensor to move toward the machine base. When the extrusion plate is blocked to a certain extent, the pressure sensor comes into contact with the machine base so as to detect the degree of blockage of the extrusion plate in a timely manner.

[0010] Preferably, the extrusion plate has an extrusion hole, the intermediate rod and the connecting sleeve are axially slidingly engaged, and the cleaning component includes a hole cleaning component, an auxiliary component and a discharge component. The hole cleaning component is slidably mounted on the machine base for cleaning the extrusion hole. The auxiliary component is connected to the intermediate rod. When the intermediate rod rotates in the reverse direction, the auxiliary component drives the intermediate rod to move away from the extrusion plate. The discharge component is located at the bottom of the pushing chamber for discharging the cleaned bentonite raw material from the pushing chamber.

[0011] Its effect is that the auxiliary component moves the intermediate rod away from the extrusion plate, and after the cleaning component cleans the blocked extrusion holes, the discharge component can discharge the cleaned bentonite raw material.

[0012] Preferably, the hole-cleaning component includes: a hole-cleaning plate slidably mounted on the machine base toward the extrusion plate, a push rod disposed on the side of the hole-cleaning plate, and a connecting rod connecting the hole-cleaning plate and the intermediate rod. The connecting rod passes through the extrusion plate and connects to the intermediate plate. The hole-cleaning plate is disposed outside the pushing chamber. The push rod is disposed corresponding to the extrusion hole. When the intermediate rod moves axially, the hole-cleaning plate drives the push rod to move into the extrusion hole to push out the bentonite raw material blocked in the extrusion hole.

[0013] Its effect is that when the intermediate rod moves, it drives the cleaning plate to move, and the movement of the cleaning plate drives the push rod to move until the push rod moves into the extrusion hole, squeezing out the bentonite raw material that is blocking the extrusion hole, thus cleaning the extrusion hole.

[0014] Preferably, the auxiliary components include a control plate, a baffle, a second spring, and a second locking block. The control plate is axially slidably mounted on the intermediate rod. The second locking block is located on the side of the control plate. The inner wall of the feeding chamber has a threaded groove and an annular groove that are interconnected. There are two annular grooves at both ends of the threaded groove. The second locking block slides in the annular groove and the threaded groove. When the second locking block slides in the threaded groove, it drives the control plate to move relative to the intermediate rod. The baffle is located on the intermediate rod. After the control plate moves to abut against the baffle, it drives the intermediate rod to move away from the extrusion plate. The second spring cooperates with the control plate and the inner wall of the feeding chamber respectively. The second spring is used to drive the control plate to move towards the extrusion plate.

[0015] Its effect is that the intermediate rod rotates in the opposite direction, causing the second locking block to engage with different positions in the second threaded groove. At the same time, the control plate moves relative to the intermediate rod. After the control plate comes into contact with the baffle, it drives the intermediate rod to move, thereby driving the intermediate rod and the spiral plate away from the extrusion plate, so that the blocked bentonite raw material can be cleaned up in a concentrated manner afterward.

[0016] Preferably, the machine base has a discharge port that communicates with the bottom of the pushing chamber. The discharge component includes a slide plate and a support plate. The support plate is slidably disposed in the discharge port. The slide plate is slidably mounted on the machine base. The slide plate is connected to the support plate. The movement of the slide plate causes the support plate to separate from the discharge port to open the pushing chamber.

[0017] Its effect is that the sliding plate moves the pallet away from the pushing chamber, while opening the discharge port so that the blocked bentonite raw material can be discharged from the pushing chamber.

[0018] Preferably, the discharge port is located close to the extrusion plate, and after the intermediate rod moves and separates from the extrusion plate, the discharge port is located between the spiral plate and the extrusion plate.

[0019] Its effect is that after the spiral plate moves away from the extrusion plate, the discharge port is located between the two, reducing the phenomenon of the spiral plate interfering with the discharge of bentonite raw materials, so that all the cleaned bentonite raw materials can be discharged.

[0020] Preferably, the sliding direction of the slide plate is perpendicular to the sliding direction of the hole-cleaning plate. The slide plate is provided with a guide groove, the bottom of which is inclined towards the hole-cleaning plate. The hole-cleaning plate is provided with a guide rod, the end of which is close to the slide plate and slides in cooperation with the guide groove.

[0021] Its effect is that the middle rod drives the cleaning plate to move while simultaneously driving the guide rod to move. The guide rod cooperates with different positions in the guide groove to drive the slide plate to move, thereby achieving the adjustment of the position of the support plate while the cleaning plate moves.

[0022] Preferably, the end of the intermediate rod extends into the sleeve 1, and the sleeve 1 is provided with a spring 3, which is connected to the end of the intermediate rod. The spring 3 is used to drive the intermediate rod to move toward the extrusion plate.

[0023] Its effect is that by setting spring three, after the extrusion plate is cleaned, spring three will drive the intermediate rod to move to the initial position, and at the same time facilitate the reprocessing of the adsorbent.

[0024] Preferably, an auxiliary plate is provided at intervals on the side of the control plate near the extrusion plate. The outer side of the auxiliary plate slides against the inner wall of the feeding chamber. A connecting sleeve is provided between the auxiliary plate and the control plate to connect the two. The auxiliary plate is used to prevent the bentonite raw material from entering the annular groove and the threaded groove.

[0025] Its effect is that after the intermediate rod and control plate move, the auxiliary plate will block the flow, reducing the occurrence of bentonite raw material entering the annular groove and the threaded groove, and ensuring the stability of the engagement between the second locking block and the annular groove and the threaded groove.

[0026] Beneficial effects: The present invention is designed such that when the extrusion plate gradually becomes clogged, the resistance on the spiral plate and the intermediate rod gradually increases, and at the same time, the second connecting sleeve rotates relative to the first connecting sleeve. At this time, the induction plate drives the pressure sensor to move. When cleaning is required or when the extrusion plate becomes clogged to a certain extent, the induction plate drives the pressure sensor to abut against the machine base, and the driving component drives the spiral plate to rotate in the opposite direction, so as to avoid excessive compression of the bentonite raw material or overload of the equipment when the extrusion plate is clogged.

Detailed Implementation

[0036] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] like Figures 1 to 8As shown, the adsorbent granulation apparatus of the present invention includes a base 1, a feed hopper 11, a pushing chamber 2 disposed within the base 1, and an extrusion plate 3 disposed at the edge of the pushing chamber 2. The feed hopper 11 and the pushing chamber 2 are connected, and the extrusion plate 3 has a plurality of extrusion holes 31. The base 1 is provided with: a pushing component 4 for pushing the bentonite raw material in the pushing chamber 2 to the extrusion plate 3; a control component 5 for controlling the conveying direction of the bentonite raw material; and a cleaning component 6 for cleaning the extrusion plate 3 and removing any blockages caused by the bentonite raw material.

[0038] Bentonite raw material is added to the feeding chamber 2 through the feeding hopper 11. Then, the feeding assembly 4 moves the bentonite raw material in the feeding chamber 2 toward the extrusion plate 3, and extrudes the bentonite raw material through the extrusion hole 31 for molding. When the extrusion hole 31 is blocked to a certain extent, the control assembly 5 controls the feeding assembly 4 to reverse the feeding of the bentonite raw material to avoid excessive compression of the bentonite raw material. Then, the cleaning assembly 6 cleans the extrusion hole 31 and the blocked bentonite raw material.

[0039] Reference Figure 1 and Figure 4 The feeding assembly 4 includes a spiral plate 41, an intermediate rod 42, and a driving component 43. The intermediate rod 42 is rotatably arranged in the feeding chamber 2 and is arranged in the direction of the extrusion plate 3. The spiral plate 41 is arranged in a spiral shape along the length of the intermediate rod 42. The driving component 43 is a motor and is arranged on the machine base 1. The intermediate rod 42 passes through the machine base 1 and is connected to the output shaft of the driving component 43 through the control assembly 5.

[0040] In this embodiment, the intermediate rod 42 and the spiral plate 41 rotate in both directions. When rotating in the forward direction, the spiral plate 41 drives the bentonite raw material to be transported to the extrusion plate 3. When rotating in the reverse direction, the spiral plate 41 drives the bentonite raw material away from the extrusion plate 3.

[0041] The drive unit 43 drives the intermediate rod 42 to rotate through the control component 5. The intermediate rod 42 drives the spiral plate 41 to rotate. The rotation of the spiral plate 41 pushes the bentonite raw material in the pushing chamber 2 to the extrusion plate 3. At the same time, the drive unit 43 can drive the spiral plate 41 to rotate in the opposite direction, causing the bentonite raw material to move away from the extrusion plate 3 in the opposite direction, so as to realize the conveying of bentonite raw material in different directions.

[0042] Reference Figure 2 and Figure 3The control component 5 includes a first sleeve 51, a second sleeve 52, a first spring 53, and a sensor 54. The first sleeve 51 and the second sleeve 52 are coaxially arranged with the intermediate rod 42. The first sleeve 51 and the second sleeve 52 are located between the intermediate rod 42 and the output shaft of the drive member 43. The first sleeve 51 is connected to the output shaft of the drive member 43, and the second sleeve 52 is connected to the intermediate rod 42. The inner wall of the second sleeve 52 is spaced apart from the first sleeve 51. The first spring 53 is a torsion spring, which is located between the second sleeve 52 and the first sleeve 51. The first spring 53 is connected to both the first sleeve 51 and the second sleeve 52. The sensor 54 is located inside the second sleeve 52 and is used to detect the torque on the intermediate rod 42.

[0043] The driving component 43 drives the first connecting sleeve 51 to rotate, and the first connecting sleeve 51 drives the second connecting sleeve 52 to rotate through the first elastic component 53. The second connecting sleeve 52 drives the intermediate rod 42 to rotate, which in turn drives the spiral plate 41 to rotate.

[0044] Reference Figure 2 , Figure 3 , Figure 8 The sensing element 54 includes a sensing plate 541 and a pressure sensor 542. A threaded groove 7 is circumferentially formed on the inner wall of the connecting sleeve 52. The sensing plate 541 is fitted onto the outside of the connecting sleeve 51 and slides axially on the outside of the connecting sleeve 51. A locking block 71 is provided on the outer side of the sensing plate 541, and the locking block 71 slides within the threaded groove. The pressure sensor 542 is located on one side of the sensing plate 541. When the sensing plate 541 slides relative to the connecting sleeve 51, it can cause the pressure sensor 542 to abut against the base 1. A controller is provided on the base 1. The controller is electrically connected to the pressure sensor 542 to receive the signal detected by the pressure sensor 542. The control terminal of the controller is electrically connected to the driving element 43 to control the driving element 43 to drive in different directions.

[0045] When the spiral plate 41 conveys the bentonite raw material and the extrusion hole 31 becomes blocked, the resistance to the rotation of the spiral plate 41 increases. As the connecting sleeve 51 continues to rotate, the connecting sleeve 52 rotates relative to the connecting sleeve 51 and twists the spring 53. At the same time, it drives different positions in the spiral groove to cooperate with the locking block 71, causing the sensing plate 541 to slide. The sliding of the sensing plate 541 causes the pressure sensor 542 to gradually move to abut against the machine base 1. After the extrusion hole 31 is blocked to a certain extent, the sensing element 54 drives the pressure sensor 542 to move to abut against the machine base 1. Then, the pressure sensor 542 sends a signal to the controller, and the controller controls the drive element 43 to rotate in the opposite direction, thereby driving the spiral plate 41 to convey the bentonite raw material in the opposite direction to prevent the spiral plate 41 from over-squeezing the bentonite raw material.

[0046] The intermediate rod 42 is slidably engaged with the connecting sleeve 52, so that the intermediate rod 42 can slide axially relative to the connecting sleeve 52 when it rotates with the connecting sleeve 52.

[0047] Reference Figure 1 , Figure 4 and Figure 5 The cleaning component 6 includes a cleaning component 61, an auxiliary component 62, and a discharge component 63. The cleaning component 61 is used to clean the extrusion hole 31. The auxiliary component 62 is connected to the intermediate rod 42 to drive the spiral plate 41 away from the extrusion plate 3, so that a space is left between the spiral plate 41 and the extrusion plate 3 for temporarily storing the blocked bentonite raw material. Then, the blocked bentonite raw material is discharged from the push chamber 2 through the discharge component 63.

[0048] Reference Figure 4 and Figure 5 The hole cleaning component 61 includes a hole cleaning plate 611, a push rod 612, and a connecting rod 613. The hole cleaning plate 611 is mounted on the machine base 1 and slides on the machine base 1 in the direction toward the extrusion plate 3. The push rod 612 is mounted on the side of the hole cleaning plate 611 close to the extrusion plate 3. Multiple push rods 612 are provided, and multiple push rods 612 are corresponding to multiple extrusion holes 31. The push rods 612 can be moved and inserted into the extrusion holes 31 to clean the extrusion holes 31. One end of the connecting rod 613 is connected to the hole cleaning plate 611, and the other end passes through the extrusion plate 3 and is connected to the intermediate rod 42. The intermediate rod 42 slides axially in the pushing chamber 2. The auxiliary component 62 is connected to the intermediate rod 42 and is used to drive the intermediate rod 42 to move axially when the intermediate rod 42 rotates in the opposite direction.

[0049] When the intermediate rod 42 rotates in the reverse direction, the auxiliary component 62 drives the intermediate rod 42 away from the extrusion plate 3. At the same time, the connecting rod 613 drives the cleaning plate 611 to approach the extrusion hole 31, and then drives the top rod 612 to insert into the extrusion hole 31, pushing out the bentonite raw material blocked in the extrusion hole 31, thereby cleaning the extrusion hole 31.

[0050] Reference Figure 1 , Figure 6 and Figure 7The auxiliary component 62 includes a control plate 621, an auxiliary plate 622, a baffle 623, a second spring 624, and a second locking block 625. A threaded groove 8 and an annular groove 81 are formed on the inner wall of the pushing chamber 2. The threaded groove 8 is arranged along the length of the intermediate rod 42. Two annular grooves 81 are provided, with each annular groove 81 located at one end of the threaded groove. The threaded groove 8 and the annular groove 81 communicate with each other. The control plate 621 is axially slidable outside the intermediate plate. The second locking block 625 is located outside the control plate 621 and slides within the annular groove 81 and the threaded groove. The second spring 624 is an elastic telescopic rod, capable of elastic telescopic movement. One end of the rod is connected to the inner wall of the feeding chamber 2, and the other end abuts against the control plate 621. The spring 624 is used to drive the control plate 621 to slide in the direction toward the extrusion plate 3. The baffle 623 is fixedly set outside the intermediate rod 42. The control plate 621 can slide to abut against the baffle 623. The auxiliary plate 622 is set on the side of the control plate 621 close to the extrusion plate 3, and the auxiliary plate 622 and the control plate 621 are arranged at intervals. A connecting sleeve 626 is provided between the auxiliary plate 622 and the control plate 621 to connect the two. The connecting sleeve 626 is sleeved on the outside of the intermediate rod 42, and the outer side of the auxiliary plate 622 slides against the inner wall of the feeding chamber 2.

[0051] In the initial state, the control plate 621 and the baffle 623 are spaced apart, and the second locking block 625 rotates in the annular groove 81. When the intermediate rod 42 rotates in the reverse direction, it drives the second locking block 625 to rotate into the second threaded groove 8. The second locking block 625 and the second threaded groove 8 are in different positions, which drives the control plate 621 to slide relative to the intermediate rod 42, and at the same time drives the auxiliary plate 622 to slide. After the control plate 621 slides to abut against the baffle 623, the intermediate rod 42 continues to rotate. The control plate 621 moves while driving the intermediate rod 42 to move, thereby adjusting the position of the intermediate rod 42 until the second locking block 625 rotates into another annular groove 81. After the blocked bentonite raw material is cleared, the intermediate rod 42 rotates in the reverse direction. Under the action of the second spring 624, it drives the second locking block 625 to enter the other annular groove 81 again through the second threaded groove 8, and drives the intermediate rod 42 to move to the initial position. In addition, the auxiliary plate 622 moves with the control plate 621. After the control plate 621 stops moving, the auxiliary plate 622 moves to the annular groove 81 to block the annular groove 81, reducing the occurrence of bentonite raw material entering the annular groove 81 and the threaded groove 8, and ensuring the stability of the engagement between the second locking block 625 and the annular groove 81 and the threaded groove 8.

[0052] Reference Figure 2 and Figure 3The end of the intermediate rod 42 extends into the first sleeve 51. The intermediate rod 42 rotates within the first sleeve 51 and slides along its own axis. A spring 421 is provided within the first sleeve 51. One end of the spring is connected to the intermediate rod 42, and the other end is connected to the inner wall of the second sleeve 52. When the intermediate rod 42 moves axially, it compresses the spring 421, causing it to deform. After the control plate 621 is reset and separated from the baffle 623, the spring 421 can drive the intermediate rod 42 to its initial position. Furthermore, in this embodiment, the spring 421 is always in a compressed state. In the initial state, the thrust exerted by the spring 421 on the intermediate rod 42 is greater than the thrust of the spiral plate 41 pushing the bentonite raw material, so that the spiral plate 41 pushes the bentonite raw material to the designated position.

[0053] Reference Figure 4 and Figure 5 The machine base 1 has a discharge port 12, which is located at the bottom of the pushing chamber 2 and communicates with it. The discharge component 63 includes a slide plate 631 and a support plate 632. The support plate 632 is located at the bottom of the pushing chamber 2 and is slidably disposed in the discharge port 12. An arc-shaped groove is provided on the side of the support plate 632, which corresponds to the inner wall of the pushing chamber 2. The slide plate 631 is located on the side of the support plate 632 and is mounted on the machine base 1 by sliding up and down. Moving the slide plate 631 causes the support plate 632 to move away from the pushing chamber 2, opening the bottom of the pushing chamber 2 so that the bentonite raw material that has been cleared from the extrusion hole 31 can be discharged from the pushing chamber 2.

[0054] Reference Figure 4 and Figure 5 The discharge port 12 is located near the extrusion plate 3, that is, the support plate 632 is located near the extrusion plate 3. When the intermediate rod 42 moves axially, the intermediate plate drives the spiral plate 41 and the extrusion plate 3 to move to a certain distance. The gap between the spiral plate 41 and the extrusion plate 3 corresponds to the support plate 632, so that when the moving support plate 632 opens the pushing chamber 2, all the cleaned bentonite raw materials are discharged.

[0055] Reference Figure 4 and Figure 5The slide plate 631 slides vertically, meaning its sliding direction is perpendicular to that of the cleaning plate 611. A guide rod 9 is mounted on the cleaning plate 611, and a guide groove 91 is formed on the side of the slide plate 631. The bottom of the guide groove 91 is inclined towards the cleaning plate 611. One end of the guide rod 9, away from the cleaning plate 611, slides within the guide groove 91. Specifically, a guide block is integrally mounted on the guide rod 9, and the guide block slides in cooperation with the guide groove 91. The guide block is located on the side of the guide rod 9 closest to the slide plate 631 (not shown in the figure). When the cleaning plate 611 moves towards the extrusion plate 3, it causes the guide rod 9 to engage with different positions within the guide groove 91, thus moving the slide plate 631. The movement of the slide plate 631 causes the support plate 632 to separate from the pushing chamber 2, opening the pushing chamber 2.

[0056] The implementation principle of this invention is as follows: Bentonite raw material enters the pushing chamber 2 through the feeding hopper 11. The driving component 43 drives the spiral plate 41 to rotate, extruding and conveying the bentonite raw material to the extrusion plate 3. Then, it is formed through the extrusion hole 31. When the extrusion hole 31 is blocked, the connecting sleeve 2 52 rotates relative to the connecting sleeve 1 51, driving the sensing plate 541 to move. The sensing plate 541 drives the pressure sensor 542 to move. After the extrusion hole 31 is blocked to a certain extent, the sensing plate 541 drives the pressure sensor 542 to abut against the machine base 1 and sends a signal to the controller. After receiving the signal, the controller controls the driving component 43 to drive the spiral plate 41 in the reverse direction. The spiral plate 41 rotates in the reverse direction, driving the bentonite raw material to be conveyed in the reverse direction, reducing the excessive extrusion of the bentonite raw material.

[0057] Simultaneously, the spiral plate 41 rotates in the reverse direction, causing the second clamping block 625 to enter the spiral groove and move the auxiliary plate 622. The auxiliary plate 622 moves until it abuts against the baffle 623, causing the intermediate rod 42 to move. The movement of the intermediate rod 42 causes the spiral plate 41 to move until it separates from the extrusion plate 3. At the same time, the intermediate rod 42 moves the cleaning plate 611 through the connecting rod 613. The cleaning plate 611 moves the top rod 612 into the extrusion hole 31 to clean the extrusion hole 31. At the same time, the cleaned bentonite raw material is pushed between the extrusion plate 3 and the spiral plate 41. When the cleaning plate 611 moves, it moves the support plate 632 through the sliding plate 631 until it separates from the pushing chamber 2, opening the pushing chamber 2 and discharging the cleaned bentonite raw material. After cleaning, the driving component 43 returns to the initial direction of driving. The auxiliary plate 622, under the action of the second spring 624, the intermediate rod 42, under the action of the third spring 421, and the support plate 632 all return to their initial positions, conveying the bentonite raw material again. By setting the sensing plate 541 and pressure sensor 542, when the extrusion hole 31 is blocked to a certain extent, the spiral plate 41 is controlled to rotate in the opposite direction, which reduces the phenomenon of overload and excessive compression of bentonite raw material by the driving component 43 and the spiral plate 41. At the same time, the push rod 612 is driven to move into the extrusion hole 31 to clean the extrusion hole 31, thereby improving the processing quality and processing efficiency.
