Description

Technical Field

[0001] The invention relates to the technical field of centrifugal processing of titanate coupling agent raw materials, in particular to centrifugal processing preparation equipment for titanate coupling agent production and a preparation method thereof. Background Art

[0002] When using stearic acid ester as raw material to produce titanate coupling agent, it is necessary to perform centrifugal water washing and dehydration treatment on the fixed stearic acid masterbatch. The centrifuge is one of the equipments for performing centrifugal water washing and dehydration treatment on the fixed stearic acid masterbatch. The centrifuge can quickly separate the fixed stearic acid masterbatch from the liquid.

[0003] The traditional centrifuge equipment consists of an inner cylinder and an outer cylinder. The fixed stearic acid masterbatch is placed in the inner cylinder. The centrifugal force of the fixed stearic acid masterbatch is increased by the rotation of the inner cylinder, so that the liquid on its surface is centrifugally thrown out to achieve the dehydration effect. However, there is a certain adsorption effect between the liquid and the fixed stearic acid masterbatch. When the fixed stearic acid masterbatch and the rotating cylinder rotate synchronously, the liquid and the fixed stearic acid masterbatch are in a relatively balanced state. In this case, the rotation speed of the inner cylinder needs to be increased to continue to dehydrate the surface of the fixed stearic acid masterbatch. The traditional centrifuge can only improve the dehydration effect of the fixed stearic acid masterbatch by continuously increasing the rotation speed of the inner cylinder. Summary of the invention

[0004] In order to solve the problem that the traditional centrifuge can only improve the effect of dehydration treatment of fixed stearic acid masterbatch by continuously increasing the internal rotation speed, the present invention is implemented through the following technical scheme: a centrifugal processing and preparation equipment for the production of titanate coupling agent, comprising a bottom plate, a leg is installed on the lower surface of the bottom plate, an outer cylinder is fixedly installed on the upper surface of the bottom plate, an inner cylinder is rotatably installed inside the outer cylinder, a cover plate is fixedly installed on the upper surface of the outer cylinder, a feed cylinder is installed on the surface of the cover plate, and the titanate coupling agent raw material is transported into the inner cylinder by the feed cylinder, a support disk is arranged inside the inner cylinder, and the support disk is fixedly connected to the cover plate;

[0005] A plurality of guide plates are rotatably mounted on the lower surface of the support plate. The positional relationship between the guide plates and the inner annular surface of the inner cylinder is adjusted by rotating the guide plates. When the gap between the side edge of the guide plate close to the inner cylinder and the inner annular surface of the inner cylinder is smaller than the particle size of the titanate coupling agent raw material, the particles of the titanate coupling agent raw material rotating with the inner cylinder come into contact with the guide plates and move along the surface of the guide plates on the side away from the rotation direction of the inner cylinder.

[0006] When the titanate coupling agent raw material particles rotate with the inner cylinder, the position of the guide plate is rotated to adjust so that the gap between the side edge of the guide plate and the inner annular surface of the inner cylinder is smaller than the particle size of the titanate coupling agent raw material. When the titanate coupling agent raw material particles move to the position of the side edge, the titanate coupling agent raw material particles move to the surface of the guide plate and continue to move along the surface of the guide plate. At this time, the movement direction of the titanate coupling agent raw material particles is changed. Finally, the titanate coupling agent raw material particles will collide with the internal structure of the inner cylinder, such as the inner side wall of the inner cylinder, the surface of other guide plates, and the surface of the rotating cylinder. When the titanate coupling agent raw material particles collide with the internal structure of the inner cylinder, the separation of the liquid on the surface of the titanate coupling agent raw material particles and the titanate coupling agent raw material particles will be accelerated to improve the removal speed and removal rate of the liquid on the surface of the titanate coupling agent raw material particles.

[0007] Furthermore, the guide plate is an arc plate, and when the side edge of the guide plate rotates to a position in sliding contact with the inner annular surface of the inner cylinder, the angle between the tangent plane of the side edge of the surface of the guide plate away from the rotation direction of the inner cylinder and the tangent plane of the inner annular surface of the inner cylinder at the side edge does not exceed 45°. The smaller the angle, the smaller the speed loss of the titanate coupling agent raw material particles when they move to the surface of the guide plate.

[0008] When the guide plates rotate to a coaxial position, the guide plates are combined to form a cylinder. When the guide plates are combined to form a cylinder, the titanate coupling agent raw material particles can be pushed toward the inner annular surface of the inner cylinder, which is beneficial to improving the effect of centrifugal dehydration treatment of the titanate coupling agent raw material particles.

[0009] Furthermore, a rotating drum is rotatably mounted on the lower surface of the support plate, and when the gap between the side edge of the guide plate and the inner annular surface of the inner drum is smaller than the particle size of the titanate coupling agent raw material, the inner side edge cut surface of the guide plate away from the side edge extends toward the surface of the rotating drum, and the particle size of the titanate coupling agent raw material moves along the surface of the guide plate. When the particles of the titanate coupling agent raw material leave the surface of the guide plate, the particles of the titanate coupling agent raw material will first collide with the surface of the rotating drum. When the rotating drum is in a rotating state and rotates in the opposite direction of the movement of the titanate coupling agent raw material, after the titanate coupling agent raw material collides with the rotating drum, the movement direction of the titanate coupling agent raw material will change, and the liquid on the surface of the titanate coupling agent raw material will adhere to the surface of the rotating drum.

[0010] Furthermore, a spiral guide groove is provided on the outer ring surface of the rotating drum, and the rotating direction of the rotating drum is opposite to the downward rotation direction of the spiral guide groove. When the rotating drum rotates, it is convenient for the liquid to flow downward to the spiral guide groove. A plurality of drainage grooves are provided between two adjacent guide grooves in the spiral guide groove. The angle between the downward inclined direction of the drainage groove and the downward rotation direction of the spiral guide groove is an acute angle, which is convenient for the liquid in the drainage groove to flow downward.

[0011] A filter plate is fixedly installed inside the inner cylinder, a circular ring is opened at the center of the filter plate, and the lower end of the rotating cylinder extends to the bottom of the filter plate through the circular ring;

[0012] A conical flow guide platform is arranged below the filter plate. The flow guide platform is fixedly installed on the bottom surface of the inner cylinder. The space where the flow guide platform is located is communicated with the space between the outer cylinder and the inner cylinder.

[0013] When the titanate coupling agent raw material collides with the surface of the drum, the liquid on the surface of the titanate coupling agent raw material will adhere to the surface of the drum due to inertia and enter the spiral guide groove or drainage groove. When the drum rotates, the liquid will flow downward along the spiral guide groove or drainage groove and finally enter the space under the filter plate.

[0014] Furthermore, the lower sides of the spiral guide groove and the drainage groove are both grooves, and the groove refers to the acute angle between the inclined side surface and the bottom surface of the spiral guide groove or the drainage groove. The inner side surface of the groove extending to the outer ring surface of the rotating drum is a guide arc surface, and the guide arc surface extends toward the inside of the spiral guide groove or the drainage groove. The groove cooperates with the guide arc surface to prevent the liquid inside the spiral guide groove or the drainage groove from being thrown out when the rotating drum rotates.

[0015] Further, a sealing cover is provided on the upper surface of the support disk, a sleeve shaft is rotatably mounted on the upper surface of the support disk, a toothed disk is fixedly mounted on the surface of the sleeve shaft, a plurality of transmission gears are rotatably mounted on the upper surface of the support disk, the plurality of transmission gears are respectively fixedly connected to the plurality of guide plates, and the plurality of transmission gears are simultaneously meshed with the toothed disk;

[0016] A shaft is rotatably mounted inside the sleeve shaft, the shaft is fixedly connected to the top surface of the drum, worm wheels are mounted on the surfaces of the sleeve shaft and the shaft rod, the worm wheels are driven to rotate by the worm, and a motor driving the worm to rotate is mounted inside the enclosure.

[0017] Furthermore, the side surface of the inner tube is provided with mesh holes, the mesh holes are strip-shaped, the mesh holes are designed to be inclined upward or downward, and the angle between the long side of the mesh holes and the vertical line of the outer annular surface of the inner tube does not exceed 60°;

[0018] A guide block is fixedly installed on the outer ring surface of the inner cylinder, and the upper surface of the guide block is flush with the lower side edge of the mesh located along the edge of the outer ring surface of the inner cylinder. The inner cylinder rotates in the opposite direction of the upper surface of the guide block. A guide groove is opened on the upper surface of the guide block, and a part of the liquid centrifuged through the mesh enters the guide groove. When the guide block rotates with the inner cylinder, the liquid in the guide groove will flow downward. A scraper is provided on the side of the guide block away from the inner cylinder, and the scraper is in frictional and sliding contact with the inner ring surface of the outer cylinder. When the inner cylinder rotates, the scraper contacts the inner ring surface of the outer cylinder to scrape the liquid on the inner ring surface of the outer cylinder downward.

[0019] Furthermore, a shaft mounting seat is fixedly mounted on the lower surface of the bottom plate, a rotating shaft is rotatably mounted inside the shaft mounting seat, the rotating shaft is fixedly connected to the inner cylinder, a motor device is fixedly mounted on the surface of the bottom plate, and the output end of the motor device is connected to the rotating shaft via a belt;

[0020] A collecting plate is fixedly installed on the outer surface of the mounting shaft seat, and an annular groove is opened on the upper surface of the collecting plate. The space between the outer cylinder and the inner cylinder is connected with the cavity inside the collecting plate through the annular groove. A connecting pipe is fixedly installed on the side surface of the collecting plate, and the outer end of the connecting pipe is connected to a pump body. The liquid entering between the outer cylinder and the inner cylinder flows downward until it enters the collecting plate through the annular groove, and the liquid in the collecting plate is pumped out by the pump body.

[0021] A centrifugal processing method for producing a titanate coupling agent comprises the following specific steps:

[0022] The solid stearic acid masterbatch is transported into the inner cylinder, and the inner cylinder is driven to rotate. The inner cylinder drives the solid stearic acid masterbatch to rotate. The rotation speed of the solid stearic acid masterbatch increases, and the centrifugal force increases synchronously. The liquid on the surface of the solid stearic acid masterbatch is thrown out under the action of the centrifugal force;

[0023] When the solid stearic acid masterbatch rotates to be synchronized with the inner cylinder, the position of the guide plate is rotated to adjust so that the gap between the side edge of the guide plate and the inner annular surface of the inner cylinder is smaller than the particle size of the solid stearic acid masterbatch;

[0024] When the solid stearic acid masterbatch moves to the position of the side edge portion, the solid stearic acid masterbatch moves to the surface of the guide plate and continues to move along the surface of the guide plate;

[0025] When the solid stearic acid masterbatch is separated from the surface of the guide plate, the solid stearic acid masterbatch first hits the surface of the drum, and the drum is in a rotating state at this time;

[0026] After the solid stearic acid masterbatch collides with the drum, the liquid on the surface of the solid stearic acid masterbatch is attached to the surface of the drum by inertia and enters the spiral guide groove or the drainage groove. The liquid flows downward along the spiral guide groove or the drainage groove and finally enters the space below the filter plate.

[0027] When the liquid centrifugally ejected through the mesh enters the guide groove, the liquid in the guide groove flows downward as the inner cylinder rotates, and at the same time, the scraper contacts the inner ring surface of the outer cylinder to scrape the liquid on the inner ring surface of the outer cylinder downward;

[0028] The liquid under the filter plate and the liquid in the space between the outer cylinder and the inner cylinder finally enter the collecting plate through the annular groove, the cover plate is separated from the outer cylinder, and the solid stearic acid masterbatch after centrifugal dehydration in the inner cylinder is obtained.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The centrifugal processing and preparation equipment for producing titanate coupling agent and the preparation method thereof are characterized in that a rotatable guide plate is arranged in an inner cylinder, and the relative position between the guide plate and the inner annular surface of the inner cylinder is controlled to change the movement direction of the solid stearic acid master particles in the inner cylinder, and the solid stearic acid master particles are caused to collide in the inner cylinder, and the movement direction of the solid stearic acid master particles is changed by the collision, so that the liquid on the surface of the solid stearic acid master particles is separated from the solid stearic acid master particles by inertia, and the dehydration effect of the surface of the solid stearic acid master particles can be improved without changing the rotation speed of the inner cylinder.

[0031] 2. The centrifugal processing equipment and preparation method for producing titanate coupling agent, through the design of the rotating drum on the lower surface of the support plate and the design of the spiral guide groove and the drainage groove on the surface of the rotating drum, can make the solid stearic acid masterbatch collide with the rotating drum and reduce the speed loss of the solid stearic acid masterbatch during the collision, while facilitating the liquid attached to the surface of the rotating drum to flow downward. The design of the mesh holes and the guide block on the surface of the inner drum and the combined design of the scraper in the guide block and the inner wall of the outer drum can increase the speed of the downward flow of the fluid between the outer drum and the inner drum.

[0046] The embodiment of the centrifugal processing equipment and preparation method for producing the titanate coupling agent is as follows:

[0047] See also Figure 1-Figure 12A centrifugal processing and preparation equipment for the production of titanate coupling agent includes a bottom plate 1, a leg is installed on the lower surface of the bottom plate 1, an outer cylinder 2 is fixedly installed on the upper surface of the bottom plate 1, an inner cylinder 3 is rotatably installed inside the outer cylinder 2, a cover plate 8 is fixedly installed on the upper surface of the outer cylinder 2, a feed cylinder 81 is installed on the surface of the cover plate 8, the feed cylinder 81 is used to transport the titanate coupling agent raw material into the inner cylinder 3, a support plate 9 is arranged inside the inner cylinder 3, and the support plate 9 is fixedly connected to the cover plate 8.

[0048] A mounting shaft seat 6 is fixedly installed on the lower surface of the base plate 1, and a rotating shaft 61 is rotatably installed inside the mounting shaft seat 6. The rotating shaft 61 is fixedly connected to the inner cylinder 3. A motor device is fixedly installed on the surface of the base plate 1, and the output end of the motor device is connected to the rotating shaft 61 through a belt.

[0049] A collecting plate 7 is fixedly installed on the outer surface of the mounting shaft seat 6, and an annular groove is opened on the upper surface of the collecting plate 7. The space between the outer cylinder 2 and the inner cylinder 3 is connected with the cavity inside the collecting plate 7 through the annular groove. A connecting pipe 71 is fixedly installed on the side surface of the collecting plate 7, and the outer end of the connecting pipe 71 is connected to the pump body. The liquid entering between the outer cylinder 2 and the inner cylinder 3 flows downward until it enters the collecting plate 7 through the annular groove, and the liquid in the collecting plate 7 is pumped out by the pump body.

[0050] A plurality of guide plates 10 are rotatably mounted on the lower surface of the support plate 9. The positional relationship between the guide plate 10 and the inner annular surface of the inner cylinder 3 is adjusted by rotating the guide plate 10. When the gap between the side edge of the guide plate 10 close to the inner cylinder 3 and the inner annular surface of the inner cylinder 3 is smaller than the particle size of the titanate coupling agent raw material, the titanate coupling agent raw material particles rotating with the inner cylinder 3 contact the guide plate 10 and move along the surface of the guide plate 10 away from the rotation direction of the inner cylinder 3.

[0051] The guide plate 10 is an arc plate. When the side edge of the guide plate 10 rotates to a position where it is in sliding contact with the inner ring surface of the inner cylinder 3, the angle between the tangent plane of the side edge of the surface of the guide plate 10 away from the rotation direction of the inner cylinder 3 and the tangent plane of the inner ring surface of the inner cylinder 3 at the side edge does not exceed 45°. The smaller the angle, the smaller the speed loss of the titanate coupling agent raw material particles when they move to the surface of the guide plate 10.

[0052] When the guide plates 10 rotate to a coaxial position, the guide plates 10 are combined to form a cylinder. When the guide plates 10 are combined to form a cylinder, the titanate coupling agent raw material particles can be pushed toward the inner annular surface of the inner cylinder 3, which is beneficial to improve the effect of centrifugal dehydration treatment of the titanate coupling agent raw material particles.

[0053] When the titanate coupling agent raw material particles rotate with the inner cylinder 3, the position of the guide plate 10 is rotated to adjust the gap between the side edge of the guide plate 10 and the inner annular surface of the inner cylinder 3 is smaller than the particle size of the titanate coupling agent raw material. When the titanate coupling agent raw material particles move to the position of the side edge, the titanate coupling agent raw material particles move to the surface of the guide plate 10 and continue to move along the surface of the guide plate 10. At this time, the movement direction of the titanate coupling agent raw material particles is changed. Finally, the titanate coupling agent raw material particles will collide with the internal structure of the inner cylinder 3, such as the inner side wall of the inner cylinder 3, the surface of other guide plates 10, and the surface of the rotating cylinder 11. When the titanate coupling agent raw material particles collide with the internal structure of the inner cylinder 3, the separation of the liquid on the surface of the titanate coupling agent raw material particles and the titanate coupling agent raw material particles will be accelerated to improve the removal speed and removal rate of the liquid on the surface of the titanate coupling agent raw material particles.

[0054] A rotating drum 11 is rotatably mounted on the lower surface of the support plate 9. When the gap between the side edge of the guide plate 10 and the inner annular surface of the inner drum 3 is smaller than the particle size of the titanate coupling agent raw material, the inner side edge cut surface of the guide plate 10 away from the side edge extends toward the surface of the rotating drum 11, and the particle size of the titanate coupling agent raw material moves along the surface of the guide plate 10. When the titanate coupling agent raw material particles are separated from the surface of the guide plate 10, the particles of the titanate coupling agent raw material will first collide with the surface of the rotating drum 11. When the rotating drum 11 is in a rotating state and rotates in the opposite direction of the movement of the titanate coupling agent raw material, after the titanate coupling agent raw material collides with the rotating drum 11, the moving direction of the titanate coupling agent raw material will change, and the liquid on the surface of the titanate coupling agent raw material will adhere to the surface of the rotating drum 11.

[0055] A spiral guide groove 111 is provided on the outer ring surface of the rotating drum 11. The rotation direction of the rotating drum 11 is opposite to the downward rotation direction of the spiral guide groove 111. When the rotating drum 11 rotates, it is convenient for the liquid to flow downward into the spiral guide groove 111. A plurality of drainage grooves 112 are provided between two adjacent guide grooves in the spiral guide groove 111. The angle between the downward inclined direction of the drainage groove 112 and the downward rotation direction of the spiral guide groove 111 is an acute angle, which is convenient for the liquid in the drainage groove 112 to flow downward.

[0056] A filter plate 4 is fixedly installed inside the inner cylinder 3, a circular ring is opened at the center of the filter plate 4, and the lower end of the rotating cylinder 11 extends to the bottom of the filter plate 4 through the circular ring; a conical guide platform 5 is arranged below the filter plate 4, and the guide platform 5 is fixedly installed on the bottom surface of the inner cylinder 3, and the space where the guide platform 5 is located is communicated with the space between the outer cylinder 2 and the inner cylinder 3.

[0057] When the titanate coupling agent raw material collides with the surface of the drum 11, the liquid on the surface of the titanate coupling agent raw material is attached to the surface of the drum 11 due to inertia and enters the spiral guide groove 111 or the drainage groove 112. When the drum 11 rotates, the liquid flows downward along the spiral guide groove 111 or the drainage groove 112 and finally enters the space below the filter plate 4.

[0058] The lower sides inside the spiral guide groove 111 and the drainage groove 112 are both grooves 12. The groove 12 refers to the acute angle between the inclined side surface and the bottom surface of the spiral guide groove 111 or the drainage groove 112. The inner side surface of the groove 12 extending to the outer ring surface of the rotating drum 11 is the guide arc surface 121. The guide arc surface 121 extends into the interior of the spiral guide groove 111 or the drainage groove 112. The groove 12 cooperates with the guide arc surface 121 to prevent the liquid inside the spiral guide groove 111 or the drainage groove 112 from being thrown out when the rotating drum 11 rotates.

[0059] A sealing cover is provided on the upper surface of the support disk 9, a sleeve shaft 13 is rotatably mounted on the upper surface of the support disk 9, a toothed disk 131 is fixedly mounted on the surface of the sleeve shaft 13, a plurality of transmission gears 132 are rotatably mounted on the upper surface of the support disk 9, the plurality of transmission gears 132 are respectively fixedly connected to the plurality of guide plates 10, and the plurality of transmission gears 132 are meshed with the toothed disk 131 at the same time.

[0060] A shaft 14 is rotatably mounted inside the sleeve 13, and the shaft 14 is fixedly connected to the top surface of the drum 11. Worms are mounted on the surfaces of the sleeve 13 and the shaft 14, and the worms are driven to rotate by the worm. A motor driving the worm to rotate is mounted inside the enclosure.

[0061] The side surface of the inner tube 3 is provided with mesh holes 31, which are strip-shaped and designed to be inclined upward or downward. The angle between the long side of the mesh holes 31 and the vertical line of the outer ring surface of the inner tube 3 does not exceed 60°.

[0062] A guide block 32 is fixedly installed on the outer ring surface of the inner cylinder 3. The upper surface of the guide block 32 is flush with the lower side edge of the edge of the outer ring surface of the inner cylinder 3 located at the mesh 31. The inner cylinder 3 rotates in the opposite direction of the upper surface of the guide block 32. A guide groove 321 is opened on the upper surface of the guide block 32. A part of the liquid centrifuged through the mesh 31 enters the guide groove 321. When the guide block 32 rotates with the inner cylinder 3, the liquid in the guide groove 321 will flow downward. A scraper 322 is provided on the side of the guide block 32 away from the inner cylinder 3. The scraper 322 is in frictional sliding contact with the inner ring surface of the outer cylinder 2. When the inner cylinder 3 rotates, the scraper 322 contacts the inner ring surface of the outer cylinder 2 to scrape the liquid on the inner ring surface of the outer cylinder 2 downward.

[0063] A centrifugal processing method for producing a titanate coupling agent comprises the following specific steps:

[0064] The solid stearic acid masterbatch is transported to the inner cylinder 3, and the inner cylinder 3 is driven to rotate. The inner cylinder 3 drives the solid stearic acid masterbatch to rotate. The rotation speed of the solid stearic acid masterbatch increases, and its centrifugal force increases synchronously. The liquid on the surface of the solid stearic acid masterbatch is thrown out under the action of the centrifugal force.

[0065] When the solid stearic acid masterbatch rotates synchronously with the inner cylinder 3, the position of the guide plate 10 is adjusted by rotation so that the gap between the side edge of the guide plate 10 and the inner annular surface of the inner cylinder 3 is smaller than the particle size of the solid stearic acid masterbatch.

[0066] When the solid stearic acid masterbatch moves to the position of the side edge portion, the solid stearic acid masterbatch moves to the surface of the guide plate 10 , and continues to move along the surface of the guide plate 10 .

[0067] When the solid stearic acid masterbatch is separated from the surface of the guide plate 10, the solid stearic acid masterbatch first hits the surface of the drum 11, and the drum 11 is in a rotating state at this time.

[0068] After the solid stearic acid masterbatch collides with the drum 11, the liquid on the surface of the solid stearic acid masterbatch is attached to the surface of the drum 11 due to inertia and enters the spiral guide groove 111 or the drainage groove 112. The liquid flows downward along the spiral guide groove 111 or the drainage groove 112 and finally enters the space below the filter plate 4.

[0069] When the liquid centrifugally ejected through the mesh 31 enters the guide groove 321, as the inner cylinder 3 rotates, the liquid in the guide groove 321 flows downward, and at the same time, the scraper 322 contacts the inner ring surface of the outer cylinder 2 to scrape the liquid on the inner ring surface of the outer cylinder 2 downward.

[0070] The liquid below the filter plate 4 and the liquid in the space between the outer cylinder 2 and the inner cylinder 3 eventually enter the collecting plate 7 through the annular groove, and the cover plate 8 is separated from the outer cylinder 2, and the solid stearic acid masterbatch after centrifugal dehydration in the inner cylinder 3 is obtained.

[0071] Working principle of centrifugal processing equipment for the production of titanate coupling agent:

[0072] First, the solid stearic acid masterbatch is transported to the inner cylinder 3 through the feeding cylinder 81, and then the motor device on the surface of the bottom plate 1 is started. The motor device drives the rotating shaft 61 to rotate through the belt, and the rotating shaft 61 drives the inner cylinder 3 to rotate. The inner cylinder 3 drives the solid stearic acid masterbatch inside it to rotate. As the rotation speed of the solid stearic acid masterbatch increases, its centrifugal force will increase synchronously, and the liquid on the surface of the solid stearic acid masterbatch will be thrown out.

[0073] The liquid thrown out is filtered out through the mesh 31 or the filter plate 4 on the surface of the inner cylinder 3. When the solid stearic acid masterbatch rotates synchronously with the inner cylinder 3, the dehydration effect of the liquid on the surface of the solid stearic acid masterbatch slowly decreases. At this time, the worm and the worm wheel cooperate to drive the sleeve shaft 13 to rotate, and the sleeve shaft 13 drives the toothed disc 131 to rotate. The toothed disc 131 is engaged with the transmission gear 132 to drive the guide plate 10 to rotate, so that the gap between the side edge of the guide plate 10 and the inner ring surface of the inner cylinder 3 is smaller than the particle size of the titanate coupling agent raw material. When the solid stearic acid masterbatch moves to the position of the side edge, the solid stearic acid masterbatch moves to the surface of the guide plate 10 and continues to move along the surface of the guide plate 10. At this time, the movement direction of the solid stearic acid masterbatch changes, and finally the solid stearic acid masterbatch collides with the structure inside the inner cylinder 3.

[0074] When the solid stearic acid masterbatch leaves the surface of the guide plate 10, the solid stearic acid masterbatch first hits the surface of the drum 11. At this time, the worm and the worm wheel cooperate to drive the shaft 14 to rotate, so that the drum 11 is in a rotating state and rotates in the opposite direction of the moving direction of the solid stearic acid masterbatch. After the solid stearic acid masterbatch hits the drum 11, the liquid on the surface of the solid stearic acid masterbatch is affected by inertia, attached to the surface of the drum 11, and enters the spiral guide groove 111 or the drainage groove 112. When the drum 11 rotates, the liquid flows downward along the spiral guide groove 111 or the drainage groove 112, and finally enters the space below the filter plate 4.

[0075] Part of the liquid centrifugally ejected through the mesh 31 enters the guide groove 321. When the guide block 32 rotates with the inner cylinder 3, the liquid in the guide groove 321 will flow downward. When the inner cylinder 3 rotates, the scraper 322 contacts the inner ring surface of the outer cylinder 2 and scrapes the liquid on the inner ring surface of the outer cylinder 2 downward.

[0076] The liquid under the filter plate 4 and the liquid in the space between the outer cylinder 2 and the inner cylinder 3 finally enter the collecting plate 7 through the annular groove. The liquid in the collecting plate 7 can be pumped out by using a pump body, and then the cover plate 8 is separated from the outer cylinder 2, and the solid stearic acid masterbatch after centrifugal dehydration in the inner cylinder 3 is taken out.

[0077] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
