Description

Technical Field

[0001] This application relates to the field of resin processing technology, and in particular to a high-speed resin disperser. Background Technology

[0002] A high-speed disperser is a device that uses a motor to drive a dispersing head to rapidly agitate raw materials, causing the surrounding materials to form a rolling circulation within the mixing tank. This generates strong turbulence and shearing action in certain areas, achieving the effects of dispersing, mixing, and emulsifying the raw materials.

[0003] In the resin processing field, due to the different viscosities of various resins and the different raw materials used in their mixing, high-speed dispersers used in resin processing need to handle more complex raw materials. Simply using a dispersing head for rapid dispersion can only generate shear force in a single plane. Raw materials are prone to forming dead zones below the disc, and high-density fillers are deposited at the bottom of the tank due to gravity and cannot be effectively drawn into the shear zone, resulting in low dispersion efficiency. On the other hand, the shear direction is unidirectional and lacks axial guiding function. High-viscosity resins are prone to liquid surface accumulation during dispersion. That is, after the material is thrown towards the tank wall by centrifugal force, it cannot flow back to the center of the dispersing head, forming upper and lower layers. Ultimately, this leads to uneven composition of the raw materials added in the resin processing and large deviations in the solid content of the same batch of products. Summary of the Invention

[0004] This application proposes a high-speed resin disperser, which features a relatively enclosed space formed by an inner shearing cylinder and an outer shearing cylinder, allowing the dispersing blades to draw in raw materials from above and discharge them from below and around the edges. The differential rotation of the outer shearing cylinder and the inner shearing cylinder results in multiple discharge positions for the raw materials. The staggered shearing holes and discharge holes enhance the shearing capacity. The up-and-down movement of the built-in and external dispersing devices creates a multi-point dispersion in a three-dimensional orientation. This invention addresses the problems of reduced dispersion capacity, unidirectional shearing direction, and poor mixing capacity in existing high-speed resin dispersers when dealing with resins of different viscosities.

[0005] To achieve the above objectives, this application adopts the following technical solution: a high-speed resin disperser, comprising a frame, a rotating shaft disposed on one side of the top of the frame, an internal dispersing device disposed on the outer side of the bottom of the rotating shaft, and an external dispersing device disposed on the outer side of the internal dispersing device; the internal dispersing device comprises a rotating cylinder with multiple dispersing blades, and a shearing inner cylinder disposed on the outer side of the dispersing blades with vertical discharge holes; the external dispersing device comprises a mounting ring platform II disposed above the rotating cylinder, a mounting ring platform I fixed to the top of the mounting ring platform II, multiple outwardly inclined piston tubes disposed circumferentially at the bottom of the mounting ring platform II, and a piston rod disposed inside the piston tubes with an arc-shaped plate at its bottom end; the side wall of the arc-shaped plate is provided with circumferentially evenly distributed inclined shearing holes; the axial side wall of the rotating shaft is provided with circumferentially distributed sliding grooves, a sliding rod disposed on the inner side of the rotating cylinder is inserted into the sliding groove, and a limiting block is disposed at the top of the sliding groove; the inner side of the top of the mounting ring platform II is provided with an annular recess for the insertion of the limiting block.

[0006] Preferably, a limiting piston is provided at the top end of the piston rod, and a spring is provided between the bottom end of the limiting piston and the bottom end of the piston chamber.

[0007] Preferably, the outer wall of the mounting ring I is provided with triangularly distributed expansion blocks, and the side of the expansion block away from the mounting ring I is provided with an adjustment rod. The bottom end of the expansion block is provided with a positioning bolt to fix it to the adjustment rod.

[0008] Preferably, an adjusting tube is sleeved on the top of the adjusting rod, and an expanding piston is provided at the top end of the adjusting rod.

[0009] Preferably, the top end of the adjusting tube is fixed to the frame, and the bottom end of the adjusting tube is provided with a cover plate.

[0010] Preferably, the adjusting rod and the expanding piston have an air passage that connects to the space above the expanding piston where the adjusting tube is located. A one-way valve II is installed in the air passage. A one-way valve III and an electrically controlled one-way valve I are installed at the bottom of the adjusting tube. An electrically controlled one-way valve II is installed at the top of the adjusting tube.

[0011] Preferably, the top of the mounting ring I is provided with an annular gas gathering pipe, the gas gathering pipe is provided with a gas guide pipe I connected to the air passage, and the gas gathering pipe is provided with a gas guide pipe II connected to the top of the piston chamber.

[0012] Preferably, the gas gathering pipe is provided with a vertical exhaust pipe, and a one-way valve I is provided at the top end of the exhaust pipe.

[0013] Preferably, the central angle of the arc-shaped plate is no greater than 120 degrees.

[0014] Preferably, the diameter of the limiting piston is the same as the diameter of the piston chamber, the diameter of the expanding piston is equal to the inner diameter of the adjusting tube, and the diameter of the adjusting rod is less than the inner diameter of the adjusting tube.

[0015] This application provides a high-speed resin disperser, which, by setting an inner shearing cylinder and an outer shearing cylinder on the outside of the dispersing blades, allows the dispersing blades to draw resin from above into the inner shearing cylinder when rotating. After being cut by the dispersing blades and subjected to centrifugal force, a portion of the resin is discharged from the holes in the inner and outer shearing cylinders, while the remaining resin is discharged from below, creating a high pressure below. Due to the suction above the dispersing blades, a low pressure is created in the upper layer of the raw material. Under the pressure difference, the raw material discharged from below surges upward again, and after reaching the upper layer, it is recirculated into the space of the dispersing blades, thereby providing forced circulation of the raw material.

[0016] Meanwhile, vertical discharge holes are opened on the inner shearing cylinder, and inclined shearing holes are opened on the outer shearing cylinder. This allows the discharge holes to quickly pass through the shearing holes as the inner shearing cylinder rotates with the dispersing blades, forming a shearing action by intersecting with the shearing holes. As a result, the raw materials passing through the discharge holes and shearing holes can obtain a stronger shearing effect, enhancing the shearing and dispersing effect.

[0017] Meanwhile, the rotating drum equipped with the dispersing blades is not axially fixed. At this time, the rotating dispersing blades draw in raw materials from above and discharge them from below, resulting in a low-pressure zone above the dispersing blades, which provides downward suction. When the blades rotate to a certain position, their direction of motion forms a certain angle with the direction of fluid flow, resulting in an increase in local velocity and a decrease in pressure (according to Bernoulli's principle), thereby drawing in material. At this time, the blade surface will be subjected to downward suction from the fluid (due to pressure difference). When the blades rotate to another position, their direction of motion pushes the fluid downward and accelerates, resulting in an increase in local pressure and the discharge of material. At this time, the blade surface will be subjected to upward thrust from the fluid (due to pressure difference). Therefore, the rotating drum with dispersing blades will have periodic up-and-down reciprocating motion, which allows the dispersing blades to effectively disperse the raw materials within a certain three-dimensional range.

[0018] Simultaneously, as the raw material passes through the discharge hole and shear hole, it impacts the inclined surface of the shear hole, causing the outer shear cylinder to experience circumferential thrust. Since it is not directly driven by the inner shear cylinder, the circumferential rotation speed of the outer shear cylinder is slower than that of the inner shear cylinder. This differential rotation causes the raw material between the outer and inner shear cylinders to be guided to another direction before being discharged from the shear hole, making the movement path of the raw material leaving the shear hole more complex. The mixing direction of this part of the raw material with the upward-flowing raw material is also more complex, further increasing the turbulence state here. Moreover, the raw material that does not directly pass through the shear hole will impact the outer shear cylinder in a straight line, causing the outer shear cylinder to tilt downward away from the inner shear cylinder. Due to the dynamic changes of the raw material, the magnitude of the thrust on the outer shear cylinder changes in real time, causing the outer shear cylinder to tilt upward and reset under the action of the spring when the thrust decreases. This creates an additional dynamic space between the outer and inner shear cylinders. The raw material temporarily passing through this space also changes its flow direction due to the change in the dynamic space, which undoubtedly further deepens the turbulence state.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0033] Example 1

[0034] Please see Figure 1 A high-speed resin disperser includes a frame 1, on which a hydraulic transmission device, a PLC controller, and a drive motor, as found in conventional dispersers, are mounted.

[0035] See Figures 1 to 3 Three triangularly distributed adjustment tubes 7 are fixedly installed on one side of the frame 1. The bottom end of the adjustment tube 7 is bolted to a cover plate 101, and a dispersion tank is installed below the cover plate 101.

[0036] An adjusting rod 71 is movably sleeved inside the adjusting tube 7. The adjusting rod 71 movably passes through the cover plate 101, and the part of the cover plate 101 that passes through the adjusting rod 71 is in contact with the side wall of the adjusting rod 71.

[0037] The diameter of the adjusting rod 71 is smaller than the inner diameter of the adjusting tube 7. The top end of the adjusting rod 71 is fixedly connected to an expanding piston. The diameter of the expanding piston is equal to the inner diameter of the adjusting tube 7, so that the adjusting rod 71 can reciprocate axially inside the adjusting tube 7. During the movement, when the expanding piston moves to the bottom, it will be blocked by the cover plate 101 and will not leave the inner cavity of the adjusting tube 7.

[0038] The cover plate 101 is movably sleeved with a rotating shaft 2. The top of the rotating shaft 2 is connected to a drive motor fixed on the frame 1, so that the drive motor can drive the rotating shaft 2 to rotate quickly, providing power for decentralized operations.

[0039] See Figures 1 to 2 , Figures 4 to 6 The bottom outer side of the rotating shaft 2 is movably sleeved with a mounting ring platform I4, and three circumferentially distributed expansion blocks 41 are fixedly connected to the outer wall of the mounting ring platform I4.

[0040] The bottom end of the expansion block 41 is threaded with a positioning bolt 42 on the side away from the mounting ring platform I4. The bottom end of the adjusting rod 71 is fixedly connected to the part where the positioning bolt 42 passes through the expansion block 41, so that the positioning bolt 42 connects the adjusting rod 71 to the expansion block 41, so that the mounting ring platform I4 and the adjusting rod 71 can become a whole body and can move synchronously and in the same direction during movement. Moreover, the mounting ring platform I4 can be stably sleeved on the outside of the rotating shaft 2 under the hoisting of the triangularly distributed adjusting rods 71.

[0041] See Figures 1 to 2 , Figures 4 to 7 The bottom of the mounting ring platform I4 is fixedly connected to the mounting ring platform II43 by bolts. Three circumferentially distributed piston tubes 6 are fixedly connected to the bottom of the side wall of the mounting ring platform II43. A piston chamber 61 is opened in the piston tube 6. A piston rod 62 is movably sleeved in the piston chamber 61. The bottom end of the piston rod 62 movably passes through the bottom end of the piston tube 6 and is fixedly connected to an arc plate 64, so that when the mounting ring platform I4 makes axial displacement, the arc plate 64 can be driven to move synchronously and in the same direction through the mounting ring platform II43.

[0042] An inclined shearing hole is provided on the circumferential side wall of the arc plate 64. The inclination angle of the shearing hole is between 110 degrees and 120 degrees, so that when adjacent arc plates 64 approach each other, the circumferential side walls will not stick together or collide, thus avoiding the problem of jamming caused by the collision between adjacent arc plates 64.

[0043] The shearing hole is tilted in the opposite direction to the rotation direction of the shaft 2, so that when the shaft 2 rotates, the raw material thrown out towards the arc plate 64 can, along the rotation direction, part of it tilts and hits the arc plate 64, and part of it passes through the shearing hole.

[0044] Three arc-shaped plates form a shearing outer cylinder around the perimeter.

[0045] See Figures 1 to 2 , Figure 4 , Figures 9 to 10 The side wall of the rotating shaft 2 is provided with triangularly distributed sliding grooves 21.

[0046] A rotating cylinder 3 is movably sleeved on the outer bottom of the rotating shaft 2, and three triangularly distributed sliding rods 33 are bolted to the inner wall of the rotating cylinder 3.

[0047] The slide rod 33 is slidably sleeved in the slide groove 21, and the side wall of the slide rod 33 is in contact with the inner side wall of the slide groove 21. This allows the rotating shaft 2 to circumferentially press the slide rod 33 through the slide groove 21 during rotation, thereby driving the rotating cylinder 3 to rotate synchronously. The slide groove 21 provides a motion path to guide the slide rod 33 to move axially back and forth within the slide groove 21.

[0048] A limiting block 34 is fixedly connected to the top of the slide rod 33 away from the slide groove 21. An annular groove 44 is opened on the inner side of the top of the mounting ring platform II 43. The limiting block 34 is movably inserted into the groove 44. The height of the limiting block 34 is equal to the height of the groove 44, so that the limiting block 34 is completely restricted in the groove 44 in the axial direction. This allows the rotating cylinder 3 and the mounting ring platform I 4 to move synchronously in the axial direction. At the same time, the rotating cylinder 3 is also restricted by the adjusting rod 71 due to the restriction of the mounting ring platform I 4, so that the rotating cylinder 3 will not axially separate from the rotating shaft 2.

[0049] The settling trough 44 provides space for the circumferential movement of the limiting block 34. When the rotating drum 3 rotates circumferentially, it will not directly drive the mounting ring platform I4 to rotate synchronously. Instead, it will provide a circumferential rotation friction force to the mounting ring platform I4 through the friction of the limiting block 34 against the settling trough 44.

[0050] The outer wall of the rotating drum 3 is welded with circumferentially distributed dispersing blades 31. The inclination angle of the dispersing blades 31 is no more than 60 degrees, so that when the rotating drum 3 rotates, it can drive the dispersing blades 31 to rotate rapidly, thereby enabling the dispersing blades 31 to shear and disperse the surrounding raw materials.

[0051] The end of the dispersing blade 31 away from the rotating drum 3 is fixedly connected to the shearing inner cylinder 32. Since the rotating drum 3 with the dispersing blade 31 is not axially fixed, the rotating dispersing blade 31, because it draws in raw materials from above and discharges them from below, creates a low-pressure zone above the dispersing blade 31, providing downward suction. When the blade rotates to a certain position, its direction of motion forms a certain angle with the direction of fluid flow, resulting in an increase in local velocity and a decrease in pressure (according to Bernoulli's principle), thereby drawing in material. At this time, the surface of the dispersing blade 31 will be subjected to downward suction from the fluid (due to pressure difference). When the dispersing blade 31 rotates to another position, its direction of motion pushes the fluid downward and accelerates, resulting in an increase in local pressure and the discharge of material. At this time, the surface of the dispersing blade 31 will be subjected to upward thrust from the fluid (due to pressure difference). Therefore, the rotating drum 3 with the dispersing blade 31 will have periodic up-and-down reciprocating motion, thereby enabling the dispersing blade 31 to effectively disperse the raw materials within a certain three-dimensional range.

[0052] From a macroscopic perspective, the continuous rotation of the dispersing blade 31 causes the suction and discharge processes to overlap in time, forming a continuous material circulation. However, from a microscopic perspective, each blade of the dispersing blade 31 will sequentially experience the "suction" and "discharge" stages during rotation. Therefore, at any given moment, a single blade is only in the suction or discharge state and is subjected to the corresponding force (downward suction or upward thrust).

[0053] The shearing inner cylinder 32 has circumferentially distributed discharge holes, which allow the dispersing blades 31 to rotate synchronously with the shearing inner cylinder 32. The shearing inner cylinder 32, together with the shearing outer cylinder, surrounds the dispersing blades 31, allowing the dispersing blades 31 to draw resin from above into the shearing inner cylinder 32 when rotating. After being cut by the dispersing blades 31 and subjected to centrifugal force, some of the resin will be discharged from the holes in the shearing inner cylinder 32 and the shearing outer cylinder, while some resin will be discharged from below, creating high pressure below. Due to the suction above the dispersing blades 31, low pressure is created in the upper layer of the raw material. Under the pressure difference, the raw material discharged from below surges upward again, and after reaching the upper layer, it is recirculated into the space of the dispersing blades 31, thus providing forced circulation of the raw material.

[0054] The discharge hole is vertically opened and is elongated, so that when the inner shearing cylinder 32 rotates with the dispersing blade 31, the discharge hole can quickly pass through the shearing hole, and the discharge hole and the shearing hole intersect to form a straight line and an oblique line shearing action. This allows the raw material passing through the discharge hole and the shearing hole to obtain a stronger shearing action and enhance the shearing and dispersing effect.

[0055] Example 2

[0056] Please see Figures 4 to 5 , Figures 7 to 8 Based on Embodiment 1, the piston tube 6 is inclined downwards, with the inclination direction away from the rotating shaft 2. The central angle of the arc plate 64 is no greater than 120 degrees, so that part of the raw material thrown out circumferentially from the shearing inner cylinder 32 can impact the inner wall of the arc plate 64 circumferentially, causing the arc plate 64 to be subjected to circumferential and horizontal thrust, causing the arc plate 64 to move away from the rotating shaft 2. Due to the downward inclination of the piston tube 6, the arc plate 64 will also tilt downwards as it moves away from the rotating shaft 2 due to the restriction of the piston rod 62. When the outward impact force is weakened due to the increased impact distance caused by the arc plate 64 moving away, the disordered surging of the raw material on the inner and outer sides, and the influence of the elastic force of the compressed spring 63, the outward impact force of the arc plate 64 will be weakened, causing the spring 63 to drive the arc plate 64 to tilt upwards and move closer to the rotating shaft 2 for a reset movement. This causes the arc plate 64 to perform a cyclical action of tilting downwards and tilting upwards to reset.

[0057] Furthermore, the circumferential impact on the inner wall of the arc plate 64 provides a circumferential frictional force to the arc plate 64. During this process, some raw material will also pass circumferentially through the inclined shearing hole, causing the raw material to circumferentially impact the inclined side of the shearing hole, providing a circumferential impact force to the arc plate 64. Combined with the circumferential frictional force of the internal raw material and the circumferential frictional force on the settling tank 44, the entire external dispersion device will rotate circumferentially. It should be noted that the speed of this circumferential rotation is slower than the circumferential rotation speed of the shearing inner cylinder 32. Therefore, the shearing inner cylinder 32 and the shearing outer cylinder rotate at a differential speed.

[0058] Therefore, when the arc plate 64 rotates circumferentially and makes horizontal reciprocating motions with an upward and downward tilt, the space between the inner shear cylinder 32 and the outer shear cylinder increases, and the path for the raw material to exit the outer shear cylinder lengthens. At this time, due to the circumferential rotation of the shear hole and the change in the vertical and horizontal direction, the raw material in this space, which was originally discharged in a directional manner, will have its discharge position changed circumferentially and horizontally. This makes the landing point of the raw material discharged from the outer shear cylinder more complex, and the direction of movement after discharge will also be more complex, further improving the turbulent state and enhancing the shearing, dispersion and mixing effect.

[0059] See Figure 8 A limiting piston is fixedly connected to the top end of the piston rod 62. The diameter of the limiting piston is the same as the diameter of the piston chamber 61, so that when the piston rod 62 moves axially in the piston tube 6, the limiting piston can restrict the piston rod 62 from leaving the piston tube 6.

[0060] A spring 63 is fixedly connected to the bottom end of the piston chamber 61. The top end of the spring 63 is fixedly connected to the bottom end of the limiting piston. The spring 63 is sleeved on the outside of the piston rod 62 located in the piston chamber 61. When the arc plate 64 moves away from the rotating shaft 2, it can drive the piston rod 62 to press down the spring 63 to compress and store energy. When the outward pushing force on the arc plate 64 weakens, the compressed spring 63 can drive the arc plate 64 to reset through the piston rod 62.

[0061] Example 3

[0062] Please see Figure 5 Based on Embodiment 2, an air passage is provided inside the adjusting rod 71 and the expanding piston, and the air passage is connected to the space above the expanding piston of the adjusting tube 7.

[0063] A one-way valve II 72 is fixedly connected inside the airway. When the one-way valve II 72 is opened, it will open the connection between the airway and the space above the expanding piston, and draw the gas in the space above into the airway.

[0064] See Figures 1 to 3The bottom of the adjusting pipe 7 is fixedly connected to a one-way valve III 73, which allows the space below the expanding piston of the adjusting pipe 7 to expand when the expanding piston moves upward, forming a low pressure. The one-way valve III 73 is opened to draw in air from the outside and replenish the low-pressure space. The bottom of the adjusting pipe 7 is fixedly connected to an electrically controlled one-way valve I 74 above the one-way valve III 73, and the top of the adjusting pipe 7 is fixedly connected to an electrically controlled one-way valve II 75. The electrically controlled one-way valves I 74 and II 75 are controlled by a PLC control program to open and close, so that the PLC control program can set the opening and closing times of the electrically controlled one-way valves I 74 and II 75. When the electrically controlled one-way valve I 74 is opened, the space below the expanding piston of the adjusting pipe 7 will be connected to the outside, and the gas in the space below the expanding piston of the adjusting pipe 7 will begin to be discharged. When the electrically controlled one-way valve II 75 is opened, the space above the expanding piston will be connected to the outside, and the air above the expanding piston will begin to be replenished.

[0065] See Figures 1 to 2 , Figures 4 to 6 The top of the mounting ring I4 is fixedly connected to a ring-shaped gas-gathering pipe 5.

[0066] Three circumferentially distributed air guide pipes I51 are fixedly connected to the gas gathering pipe 5. The end of the air guide pipe I51 away from the gas gathering pipe 5 is fixedly connected to the bottom of the adjusting rod 71. The air passage is connected to the gas gathering pipe 5 through the air guide pipe I51, so that the gas drawn in from the space above the expanding piston can be drawn into the gas gathering pipe 5 through the air guide pipe I51.

[0067] Three circumferentially distributed air guide pipes II 52 are fixedly connected to the gas gathering pipe 5. The end of the air guide pipe II 52 away from the gas gathering pipe 5 is fixedly connected to the top of the piston pipe 6. The space above the limiting piston in the piston chamber 61 is connected to the gas gathering pipe 5 through the air guide pipe II 52. When the piston rod 62 moves downward, it can expand the space above the limiting piston, causing the expanded space to draw in gas from the gas gathering pipe 5 through the air guide pipe II 52. At this time, a low pressure is formed in the gas gathering pipe 5. Gas is drawn into the air passage through the air guide pipe I 51, causing a low pressure to be formed in the air passage. The one-way valve II 72 is opened, allowing gas in the space above the expanding piston to be drawn into the air passage. At this time, a low pressure is formed in the space above the expanding piston. When the piston rod 62 moves upward, the gas in the space above the limiting piston will be forced into the gas gathering pipe 5 through the air guide pipe II 52. At this time, the pressure in the air passage increases, and the one-way valve II 72 will close.

[0068] After a low pressure is formed in the space above the expanding piston, the built-in dispersing device, which moves upward under the influence of the dispersing blade 31, will drive the external dispersing device to move upward as a whole. At this time, the adjusting rod 71 on the external dispersing device moves upward, causing the position of the expanding piston to move upward. At this time, the space below the expanding piston will increase due to the adjustment tube 7, causing the one-way valve Ⅲ 73 to open and draw in new gas to replenish the pressure below. When the built-in dispersing device drives the external dispersing device to move downward as a whole, the space below the expanding piston is replenished with pressure due to the adjustment tube 7, which hinders the downward movement of the expanding piston. Moreover, the space above the expanding piston is in a low-pressure state, causing the downward movement of the external dispersing device driven by the built-in dispersing device to fail. As a result, the built-in dispersing device can only drive the external dispersing device to move upward gradually, so that the dispersing blade 31 can move upward gradually in the axial direction, making three-dimensional contact with the raw materials at different levels and performing more comprehensive dispersion and shearing.

[0069] A vertical exhaust pipe 53 is fixedly connected to the gas-gathering pipe 5. The top end of the exhaust pipe 53 is fixedly connected through the cover plate 101. A one-way valve I 54 is fixedly sleeved inside the exhaust pipe 53, causing the piston rod 62 to move upward. The gas in the space above the limiting piston will be forced into the gas-gathering pipe 5 through the gas guide pipe II 52. When a high-pressure environment is formed in the gas-gathering pipe 5, the gas-gathering pipe 5 can squeeze open the one-way valve I 54 through the connected exhaust pipe 53 to discharge the excess gas from the gas-gathering pipe 5. This allows the piston rod 62 to form a sufficiently low-pressure environment in the gas-gathering pipe 5 again when it moves downward next time, opening the one-way valve II 72 and drawing in the gas in the space above the expanding piston of the adjusting pipe 7 through the air passage to form a low-pressure environment, ensuring the stable upward movement of the built-in dispersion device and the external dispersion device.

[0070] It should be noted that after the set time is reached, the electrically controlled one-way valve I 74 and electrically controlled one-way valve II 75 will open. At this time, the space above the expansion piston of the adjusting pipe 7 will be connected to the outside through the electrically controlled one-way valve II 75, and the space below the expansion piston of the adjusting pipe 7 will be connected to the outside through the electrically controlled one-way valve I 74. Moreover, the built-in dispersion device and the external dispersion device have reached a certain height. At this time, the space above the expansion piston can no longer form an effective negative pressure, and the space below the expansion piston can no longer be sealed, preventing the expansion piston from moving downward. This causes the built-in dispersion device and the external dispersion device to gradually move downward under their own weight and the pressure of the raw material. It should be noted that due to the resistance of the viscosity of the raw material, this descent is slow, which allows the dispersion blade 31 to once again make three-dimensional contact with the raw material at different levels, further improving the dispersion effect.
