Description

Technical Field

[0001] This utility model relates to the field of granulation equipment technology, and in particular to an extrusion rounding granulator. Background Technology

[0002] Powder granulation has been widely used in many fields such as pharmaceuticals, fertilizers, and food. After the powder raw materials, adsorbents and mixed liquids are thoroughly stirred and mixed, they are added to the granulator for granulation. The granulated material is then rolled into rounds by a rounding machine to facilitate subsequent packaging.

[0003] In existing production processes, to reduce the labor intensity of workers, mixers can be used to mix materials instead of manual mixing. However, due to the limitations of the mixer's paddle placement, it can only mix materials that the paddle touches during rotation, making it difficult to achieve thorough mixing of raw materials, adsorbents, and the mixture. Moreover, the mixed material needs to be transferred to a granulator by workers, which is labor-intensive and inefficient. During the material transfer process, moisture loss may occur in the mixed material, compromising the quality of granulation. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an extrusion spheronization granulator.

[0005] The solution to the technical problem of this utility model is:

[0006] An extrusion spheronization granulator, comprising:

[0007] A premixing device includes a mixing vessel, a stirring drive component, a clamping assembly, a lead screw, a stirring rod, and a limiting structure. The mixing vessel has a stirring chamber and a feed inlet and a liquid inlet communicating with the stirring chamber. The clamping assembly, the lead screw, the stirring rod, and the limiting structure are disposed within the stirring chamber. The lead screw has an axial direction in the vertical direction. The clamping assembly is threadedly connected to the lead screw. The limiting structure is arranged along the axial direction of the lead screw. The clamping assembly is slidably connected to the limiting structure. The stirring drive component is driven to the upper end of the lead screw to drive the lead screw to rotate and drive the clamping assembly to move along the axial direction of the lead screw. The stirring rod is connected to the lower end of the lead screw.

[0008] The granulation device has its inlet end connected to the outlet end of the stirring chamber.

[0009] This invention has at least the following beneficial effects: Since the extrusion spheronizing granulator has a built-in premixing device, it can automatically mix and stir the materials before spheronizing, improving granulation efficiency. The uniformly mixed materials are then granulated and spheronized, ensuring product quality. Furthermore, there is no need to transfer the mixed materials, greatly reducing the labor intensity of workers and preventing moisture loss before granulation. In addition, because the clamping assembly can move along the axial direction of the screw under the driving action of the stirring drive component, the clamping assembly drives the materials located in the stirring chamber to move up and down, enabling longitudinal conveying of the materials at the bottom of the stirring chamber. This facilitates the stirring rod at the bottom of the stirring chamber to stir the materials in each layer, improving the uniformity of mixing and further ensuring product quality.

[0010] As a further improvement to the above technical solution, the clamping assembly includes a displacement sleeve, at least one pair of grippers, and at least one set of opening and closing drive structures. The limiting structure is a limiting rod. The displacement sleeve is disposed on the outer periphery of the lead screw and is connected to the lead screw. The limiting rod is arranged in the vertical direction and passes through the displacement sleeve. The limiting rod is connected to the inner wall of the stirring chamber. The grippers are disposed on the outer periphery of the displacement sleeve. The opening and closing drive structures are respectively disposed and driven to each pair of grippers.

[0011] When the lead screw rotates under the driving action of the stirring drive component, the displacement sleeve can move along the axial direction of the lead screw due to the limiting rod's restrictive effect on it. This causes the gripper to move vertically, and in conjunction with the opening and closing drive structure to control the opening and closing of the gripper, the longitudinal conveying of materials can be achieved, thus improving the degree of material mixing.

[0012] As a further improvement to the above technical solution, the opening and closing drive structure includes a rotating shaft, a spring, an abutting rod, and two abutting blocks. The rotating shaft is connected to the displacement sleeve and is arranged radially along the displacement sleeve. Each gripper has a connecting block at its upper end. The connecting block is sleeved on the outer periphery of the rotating shaft and rotatably connected to the rotating shaft. The two ends of the spring are respectively connected to the connecting blocks of the two grippers. The two abutting blocks are respectively connected to the two grippers and located on the opposite side of the two grippers. The abutting rod is connected to the upper wall of the stirring chamber and extends downward. The abutting rod is located above the gap between the two abutting blocks. When the side wall of the abutting rod contacts the two abutting blocks, the abutting rod drives the two abutting blocks to move away from each other.

[0013] When the grippers are located at the lower part of the mixing chamber, they are in a closed state. The spring force can push the two connecting blocks away from each other, thus closing the lower end of the grippers. There is a gap at the upper end of the two grippers, allowing the material to enter between them. The grippers are braked upward with the displacement sleeve. When the displacement sleeve moves upward to the upper part of the mixing chamber, the abutment rod can be inserted into the gap between the two abutment blocks and contact them. The wall of the abutment rod can open the two abutment blocks, allowing them to move away from each other. At this time, the connecting block can rotate around the shaft, and the lower ends of the two grippers move away from each other, allowing the material to fall from the lower end of the two grippers to the upper part of the material pile.

[0014] As a further improvement to the above technical solution, the lower end of the abutment rod is a pointed tip, and the width of the abutment rod gradually increases from bottom to top. When the displacement sleeve moves to the upper part of the lead screw, the two abutment blocks respectively contact the two side walls of the abutment rod in the width direction.

[0015] Because the lower end of the abutment rod is designed as a pointed tip, and the width of the abutment rod gradually increases upwards, it is easier for the lower end of the abutment rod to enter between the two abutment blocks, thereby opening up the two abutment blocks.

[0016] As a further improvement to the above technical solution, the liquid inlet is provided with multiple inlets, which are arranged on the side wall of the mixing vessel. The extrusion rounding granulator also includes a water pump, which is provided with multiple nozzles, which are respectively located at the liquid inlets.

[0017] The water pump provides pressure for the mixture to enter the mixing chamber, allowing it to smoothly enter the mixing chamber and mix with other raw materials, thus improving preparation efficiency. Furthermore, multiple nozzles are installed on the side wall of the mixing vessel, allowing the mixture to enter the mixing chamber from multiple angles and mix with other raw materials, further improving the degree of material mixing.

[0018] As a further improvement to the above technical solution, the granulation device includes a pulse granulation component, a cutting component, and a rounding component. The inlet end of the pulse granulation component is connected to the outlet end of the stirring chamber, the inlet end of the cutting component is connected to the outlet end of the pulse granulation component, and the inlet end of the rounding component is connected to the outlet end of the cutting component.

[0019] Because the extrusion rounding granulator of this embodiment is equipped with a premixing device and a granulation device, and the granulation device includes a pulse granulation component, a cutting component and a rounding component, it can realize integrated production of material mixing, pulse granulation, material cutting and rounding. There is no need for manual transfer between each process, which further reduces the labor intensity of workers and avoids moisture loss and other situations caused during material transfer, thus further ensuring the quality of granulation and rounding.

[0020] As a further improvement to the above technical solution, the extrusion rounding granulator also includes a housing, and the mixing tank, the pulse granulation component, the cutting component and the rounding component are installed inside the housing.

[0021] The outer shell can protect other components and provide installation space, provide a relatively sealed environment for granulation and rounding, and allow the material to retain sufficient moisture.

[0022] As a further improvement to the above technical solution, the cutting assembly includes a cutting drive component and a cutting blade. The cutting drive component is connected to the outlet end of the pulse granulation component, and the output end of the cutting drive component is connected to the cutting blade to drive the cutting blade to rotate.

[0023] The rotation of the cutting blade can cut the material falling downwards from the outlet of the pulse granulation unit in order to control the particle size.

[0024] As a further improvement to the above technical solution, the rounding assembly includes a rounding disc, balls, and a rounding drive component. The rounding disc is arranged with an upward opening and is connected to the outlet end of the cutting assembly. The output end of the rounding drive component is connected to the rounding disc to drive the rounding disc to rotate. The balls are disposed on the inner wall of the rounding disc.

[0025] Driven by the rounding drive component, the rounding disc can rotate, and the material that falls from the cutting component and enters the rounding disc can rotate along the inner wall of the rounding disc to achieve the rounding effect. In addition, the ball bearings can increase the friction between the rounding disc and the material particles, and improve the rounding effect.

[0026] As a further improvement to the above technical solution, the rounding assembly also includes a suction pipe, the inlet end of which faces the inner wall of the rounding disc, and the outlet end of which is used to connect to an external suction machine. The suction pipe can be connected to the suction machine, enabling material extraction, which improves efficiency and avoids the impact of manual material removal on material quality.

[0039] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. The various technical features of this utility model can be combined interactively without contradicting each other.

[0040] Reference Figure 1 , Figure 2 and Figure 3 This utility model embodiment proposes an extrusion spheronization granulator, which is equipped with a premixing device 100 and a granulation device 200, which can automatically achieve full mixing of granulation raw materials and mixture before granulation, thereby improving product quality.

[0041] In this embodiment, refer to Figure 3 The premixing device 100 includes a mixing vessel 110, a stirring drive component 120, a clamping assembly 130, a lead screw 140, a stirring rod 150, and a limiting structure. The mixing vessel 110 is hollow and has a mixing chamber 111, with a feed inlet and a liquid inlet communicating with the mixing chamber 111. The feed inlet is used to add adsorbent and raw material powder to the mixing chamber 111, and the liquid inlet is used to add a mixture to the mixing chamber 111. The clamping assembly 130, lead screw 140, stirring rod 150, and limiting structure are respectively disposed in the mixing chamber 111. The axis of the lead screw 140 is vertical, and the stirring rod 150 is connected to the lower end of the lead screw 140. The output end of the stirring drive component 120 is drivenly connected to the upper end of the lead screw 140. Under the driving action of the stirring drive component 120, the lead screw 140 can rotate around its own central axis, driving the stirring rod 150 to rotate. The stirring rod 150 stirs the material in the mixing chamber 111. The inlet end of the granulation device 200 is connected to the outlet end of the mixing chamber 111. The material that has been fully mixed in the mixing chamber 111 directly enters the granulation device 200 for granulation and rounding operation.

[0042] It is worth noting that the premixing device 100 in this embodiment is provided with a clamping assembly 130 and a limiting structure. The limiting structure is arranged in the vertical direction and is slidably connected to the clamping assembly 130, which can restrict the clamping assembly 130 from moving in the vertical direction and prevent the clamping assembly 130 from rotating around the lead screw 140. The clamping assembly 130 is used to clamp the material in the mixing chamber 111. The clamping assembly 130 is connected to the lead screw 140 by a threaded engagement. When the lead screw 140 rotates, the clamping assembly 130 can move along the axial direction of the lead screw 140, thereby driving the material to move in the vertical direction, allowing the material located at the lower part of the mixing chamber 111 to be stirred upwards to the upper part, so that the material is mixed more thoroughly and the quality of the product obtained is higher.

[0043] It is understandable that the single drive structure of the stirring drive component 120 can simultaneously achieve the rotation of the stirring rod 150 and the displacement of the clamping component 130 in the vertical direction, reducing energy waste and making the structure of the premixing device 100 more reasonable and compact.

[0044] In some embodiments, refer to Figure 3 and Figure 4 The clamping assembly 130 includes at least one pair of grippers 133, at least one opening and closing drive structure, and a displacement sleeve 131. The limiting structure is a limiting rod 132. The displacement sleeve 131 is disposed on the outer periphery of the lead screw 140 and is connected to the lead screw 140 by a threaded engagement. The limiting rod 132 is connected to the inner wall of the stirring chamber 111 and is arranged in the vertical direction. The limiting rod 132 passes through the displacement sleeve 131. When the lead screw 140 rotates under the driving action of the stirring drive component 120, the displacement sleeve 131 will not rotate with the rotation of the lead screw 140 because the limiting rod 132 has a limiting effect on the displacement sleeve 131. Instead, it can move along the axial direction of the lead screw 140, thereby driving the grippers 133 to achieve vertical displacement.

[0045] In other embodiments, the limiting structure is a protrusion, and a groove matching the protrusion is provided at the edge of the displacement sleeve 131. The protrusion is disposed on the inner wall of the stirring chamber, and its length direction is vertical. Since the protrusion and the groove wall restrict each other, the displacement sleeve 131 can be prevented from rotating around the lead screw 140.

[0046] In some embodiments, the stirring drive component 120 is a motor. In some embodiments, the stirring drive component 120 can rotate forward and reverse, driving the lead screw 140 to rotate forward or reverse, thereby allowing the displacement sleeve 131 to reciprocate in the up-down direction. In this embodiment, the lead screw 140 is a reciprocating lead screw 140. When the stirring drive component 120 drives the lead screw 140 to rotate and moves the displacement sleeve 131 to the end of the lead screw 140, the displacement sleeve can automatically change direction.

[0047] It is understood that the opening and closing drive structure is correspondingly set with each pair of grippers 133 and is driven to connect with the corresponding grippers 133. Under the action of the opening and closing drive structure, the grippers 133 can realize the opening and closing action. Specifically, each pair of grippers 133 has two grippers 133. After the material located in the lower or middle part of the stirring chamber 111 enters between the two grippers 133, the opening and closing drive structure drives the lower ends of the two grippers 133 to keep them in contact with each other, that is, to keep the grippers 133 in a closed state. When the grippers 133 move with the displacement sleeve 131 to the upper part of the stirring chamber 111, the opening and closing drive structure drives the lower ends of the two grippers 133 to separate from each other, that is, to turn into an open state, and the material falls down from between the two grippers 133 into the upper space of the stirring chamber 111.

[0048] It is understood that the clamping assembly 130 may be provided with one or more pairs of grippers 133. In this embodiment, the clamping assembly 130 is provided with three pairs of grippers 133, and the opening and closing drive structure is provided with three sets accordingly. The three pairs of grippers 133 are evenly arranged around the central circumference of the displacement sleeve 131. It is understood that multiple pairs of grippers 133 can agitate the material at multiple positions in the stirring chamber 111, further improving the uniformity of material mixing.

[0049] In some embodiments, the opening and closing drive structure realizes the opening and closing control of the gripper 133 by electric means, and the program controls the gripper 133 to open when it moves to the upper part of the stirring chamber 111.

[0050] In this embodiment, refer to Figure 3 and Figure 4The opening and closing drive structure includes a rotating shaft 136, a spring 137, an abutment block 134, and an abutment rod 122. The rotating shaft 136 is connected to the displacement sleeve 131 and is arranged radially along the displacement sleeve 131. In a pair of grippers 133 corresponding to the opening and closing drive structure, each gripper 133 has a connecting block 135 at its upper end. The connecting block 135 is sleeved on the outer circumference of the rotating shaft 136 and rotatably connected to it. The two ends of the spring 137 are respectively connected to the connecting blocks 135 of the two grippers 133. Two abutment blocks 134 are provided, each connected to one of the two grippers 133 and located on the opposite side of the two grippers 133, with a gap between the two abutment blocks 134. The abutment rod 122 is connected to the upper wall of the mixing chamber 111 and extends downward. The abutment rod 122 is located above the gap between the two abutment blocks 134. When the displacement sleeve 131 moves upward to the upper part of the mixing chamber 111, the abutment rod 122 can be inserted into the gap between the two abutment blocks 134 and contact the two abutment blocks 134. The wall of the abutment rod 122 can open the two abutment blocks 134, so that the two abutment blocks 134 are far apart. At this time, the connecting block 135 can rotate around the rotating shaft 136, so that the spring 137 is compressed and the lower ends of the two grippers 133 open, and the material can fall from the lower ends of the two grippers 133.

[0051] When the gripper 133 is in the closed state, the elastic force of the spring 137 can push the two connecting blocks 135 away from each other, thereby closing the lower end of the gripper 133. At this time, the abutment block 134 is located on the lower side of the central axis of the rotating shaft 136, and there is a gap at the upper end of the two grippers 133, so that the material can enter between the two grippers 133 through the gap at the upper end of the two grippers 133.

[0052] In this embodiment, the gripper 133 is an arc-shaped plate.

[0053] Understandably, compared to an electrically driven opening and closing structure, this configuration reduces the number of electric components, decreases energy consumption, and lowers the production cost of the extrusion spheronizing granulator.

[0054] In some embodiments, the lower end of the abutment rod 122 is a pointed tip, and the width of the abutment rod 122 gradually increases from bottom to top. When the displacement sleeve 131 moves upward along the lead screw 140 to the upper part of the lead screw 140, the two abutment blocks 134 respectively contact the two side walls in the width direction of the abutment rod 122. As the displacement sleeve 131 continues to move upward, the width of the abutment rod 122 can guide the two abutment blocks 134 to gradually move away from each other, the lower ends of the two grippers 133 move away from each other, the grippers 133 open, and the material falls downward from between the two grippers 133.

[0055] Understandably, since the lower end of the abutment rod 122 is set as a pointed tip and the width of the abutment rod 122 gradually increases upward, it is easier for the lower end of the abutment rod 122 to enter between the two abutment blocks 134, so as to open up the two abutment blocks 134.

[0056] In this embodiment, the abutment rod 122 is triangular prism-shaped, and its side edges are parallel to the radial direction of the lead screw 140. One side of the abutment rod 122 is connected to the upper wall of the stirring chamber 111. When the displacement sleeve 131 moves to the upper part of the stirring chamber 111, the abutment block 134 contacts the other two sides of the abutment rod 122.

[0057] In some embodiments, refer to Figure 3 The extrusion spheroidizing granulator has multiple liquid inlets arranged on the side wall of the mixing vessel 110. It also includes a water pump 160 with multiple nozzles 161 installed at each liquid inlet and facing the mixing chamber 111. The water pump 160 provides pressure for the mixture to enter the mixing chamber 111, allowing it to smoothly mix with other raw materials and improve preparation efficiency.

[0058] In this embodiment, five layers of liquid inlets are arranged vertically, with multiple inlets in each layer. The inlets in the same layer are evenly distributed around the central axis of the stirring chamber 111 on the side wall of the stirring vessel 110. The number and installation position of the nozzles 161 correspond to the liquid inlets. Setting multiple liquid inlets in different positions can better facilitate the mixing of the mixture with the raw materials in various positions within the stirring chamber 111, further improving the uniformity of mixing and making it more conducive to the subsequent granulation and rounding production to form high-quality products.

[0059] In some embodiments, the extrusion spheronizing granulator further includes a sealing plug 162, which is detachably connected to the inlet end of the water pump 160 and can open or close the inlet end of the water pump 160. When it is necessary to add the mixture, the sealing plug 162 is removed, allowing the inlet end of the water pump 160 to be opened. The water pump 160 can be connected to an external water tank containing the mixture, and the water pump 160 draws the mixture into the mixing chamber 111. After the addition is complete, the sealing plug 162 is used to seal the inlet end of the water pump 160.

[0060] In some embodiments, refer to Figure 2 , Figure 5 and Figure 6 The granulation device 200 includes a pulse granulation component 210, a cutting component 220, and a rounding component 230. The inlet end of the pulse granulation component 210 is connected to the outlet end of the mixing chamber 111, the inlet end of the cutting component 220 is connected to the outlet end of the pulse granulation component 210, and the inlet end of the rounding component 230 is connected to the outlet end of the cutting component 220.

[0061] In this embodiment, the stirring tank 110, the pulse granulation component 210, the cutting component 220, and the rounding component 230 are arranged sequentially from top to bottom.

[0062] The pulse granulation component 210 is a common granulation component in the art. Its working process is as follows: the material to be granulated is uniformly fed into the pulse airflow channel of the pulse granulation component 210. Periodic pulse airflow is generated in the pulse airflow channel. Under the action of the pulse airflow, the material undergoes acceleration, deceleration, and re-acceleration. During this process, collisions and agglomeration occur between the material particles, gradually forming small particle agglomerates. The agglomerates fall from the outlet end of the pulse granulation component 210 into the cutting component 220. The cutting component 220 cuts the material to obtain material particles of appropriate size, which then fall into the rounding component 230 for rounding.

[0063] It is understood that, because the extrusion spheronizing granulator of this embodiment is equipped with a premixing device 100, a pulse granulation component 210, a cutting component 220, and a spheronizing component 230, it can realize integrated production of material mixing, pulse granulation, material cutting, and spheronizing. This component has a simple structure and strong practicality. Through its integrated design, granulation and spheronizing can be performed simultaneously, reducing the labor intensity of operators and improving production efficiency.

[0064] In some embodiments, the extrusion rounding granulator further includes a housing 300, and the mixing tank 110, pulse granulation component 210, cutting component 220 and rounding component 230 are integrated and installed through the housing 300. The mixing tank 110, pulse granulation component 210, cutting component 220 and rounding component 230 are respectively installed in the inner cavity of the housing 300.

[0065] In this embodiment, a feeding port 310 is provided at the upper end of the outer casing 300. The feeding port 310 is connected to the feed inlet of the mixing vessel 110, allowing raw materials to enter the mixing chamber 111 through the feeding port 310. A stirring drive component 120 is installed on the top of the outer casing 300, and a connecting sleeve 121 is installed at the lower end of the stirring drive component 120. The upper end of the mixing vessel 110 is connected to the upper wall of the inner cavity of the outer casing 300. The connecting sleeve 121 is located inside the mixing chamber 111, providing installation space for the abutment rod 122 and the limiting rod 132. A water pump 160 is installed on the side wall of the outer casing 300, and the inlet end of the water pump 160 is located on the outside of the outer casing 300.

[0066] Understandably, the outer shell 300 not only enables the integrated installation of various components and facilitates the transportation of the extrusion rounding granulator, but also provides a relatively sealed environment for granulation and rounding, allowing the cut material to retain sufficient moisture and avoiding the phenomenon of particle size moisture loss affecting rounding quality in the traditional step-by-step preparation process.

[0067] In this embodiment, refer to Figure 5 A support rod 211 is provided on the outer periphery of the pulse granulation component 210. The support rod 211 is connected to the inner wall of the outer shell 300 and can provide stable support for the pulse granulation component 210.

[0068] In some embodiments, the cutting assembly 220 includes a cutting drive component 221 and a cutting blade 222. The cutting drive component 221 is connected to the outlet end of the pulse granulation component 210, and the output end of the cutting drive component 221 is connected to the cutting blade 222. The cutting blade 222 rotates around its own center under the driving action of the cutting drive component 221. It can be understood that the rotation of the cutting blade 222 can cut the material falling downward from the outlet end of the pulse granulation component 210 to control the particle size.

[0069] In some embodiments, refer to Figure 6 The rounding assembly 230 includes a rounding disc 231, balls 233, and a rounding drive component 232. The rounding disc 231 is open upwards and communicates with the outlet end of the cutting assembly 220. The output end of the rounding drive component 232 is connected to the rounding disc 231. The balls 233 are disposed on the inner wall of the rounding disc 231. Under the driving action of the rounding drive component 232, the rounding disc 231 can rotate, and the material falling from the cutting assembly 220 and entering the rounding disc 231 can rotate along the inner wall of the rounding disc 231 to achieve a rounding effect.

[0070] Understandably, the ball bearing 233 increases the friction between the rolling disc 231 and the material particles, thus improving the rolling effect.

[0071] In this embodiment, both the cutting drive component 221 and the rounding drive component 232 are motors. The cutting drive component 221 and the rounding drive component 232 can work synchronously, which can uniformly cut and round the granular material and improve the efficiency of cutting and rounding.

[0072] In some embodiments, the rounding assembly 230 further includes a suction pipe 234, with its inlet end facing the inner wall of the rounding disk 231 and its outlet end for connecting to an external suction device. It is understood that the suction device is a device existing in the art, capable of providing suction to allow material to automatically leave the rounding disk 231 along the suction pipe 234. Extracting the prepared material using a suction device improves efficiency and avoids the impact on material quality caused by traditional manual discharge.

[0073] In some embodiments, the outlet end of the suction pipe 234 is provided with a mounting flange, which facilitates the connection of the suction pipe 234 to the suction machine. In this embodiment, the outlet end of the suction pipe 234 extends out of the housing 300.

[0074] In some embodiments, the extrusion rounding granulator further includes a support column 400, which is fixedly connected to the bottom of the housing 300 and is inclined outward from top to bottom. This provides sufficient and stable support for the housing 300 and its internal components, preventing instability of the extrusion rounding granulator during the granulation and rounding process and ensuring safety during production.

[0075] In some embodiments, the lower end of the support column 400 is provided with a foot pad, which can increase the friction between the lower end of the support column 400 and the placement platform, and prevent the extrusion rounding granulator from shifting due to vibration during the production process.

[0076] In the granulation production using the extrusion rounding granulator of this embodiment, raw materials and adsorbent are first added to the mixing chamber 111 through the feeding port 310, and a mixture is added to the mixing chamber 111 through the water pump 160. The stirring drive component 120 drives the lead screw 140 to rotate, causing the stirring rod 150 to rotate and stir the material in the mixing chamber 111. The displacement sleeve 131 drives the gripper 133 to move in the up and down direction.

[0077] When the displacement sleeve 131 moves downward, the material located in the lower part of the mixing chamber 111 enters between each pair of grippers 133 through the gap at the upper end of each pair of grippers 133. When the displacement sleeve 131 moves upward, the abutment rod 122 is inserted between the two abutment blocks 134, causing the lower ends of the two grippers 133 to open, thereby releasing the material clamped between the two grippers 133, allowing the material originally located in the lower part of the mixing chamber 111 to fall to the upper part. By driving the lead screw 140 to rotate through the stirring drive component 120, the grippers 133 reciprocate in the up-down direction, which can improve the degree of mixing and fully mix the material at different heights. The water pump 160 adds the mixture to the mixing chamber 111 in a metering manner. Since the multiple nozzles 161 of the water pump 160 are arranged on the side wall of the mixing vessel 110 and set in different directions, the mixture can enter the mixing chamber 111 from multiple angles and mix with the raw materials, so that the material in the mixing chamber 111 is fully mixed.

[0078] After mixing is complete, the pulse granulation unit 210 is activated, and the input port at the top of the pulse granulation unit 210 is opened. The stirred and mixed material enters the pulse granulation unit 210 and is granulated to form granular agglomerates. The agglomerates fall into the cutting assembly 220. Driven by the cutting drive unit 221, the cutting blade 222 rotates and continuously cuts the material. Simultaneously, the rounding drive unit 232 is activated, and the output end of the rounding drive unit 232 drives the rounding disc 231 to rotate continuously, rounding the granular material falling onto the rounding disc 231. After rounding, the granular material leaves the rounding disc 231 through the suction pipe 234 under the action of the suction machine and is collected for subsequent processing.

[0079] The extrusion rounding granulator of this embodiment improves the preparation quality through its integrated design. The premixing device 100 thoroughly mixes and stirs the adsorbent, mixture, and raw materials. A water pump 160 evenly sprays the mixture from nozzles 161 on the side wall of the mixing tank 110, and the stirring rod 150 further mixes the materials. The screw 140, displacement sleeve 131, and grippers 133 work together to longitudinally convey the bottom layer of material, facilitating the stirring rod 150 at the bottom of the mixing chamber 111 to stir each layer. Furthermore, the pulse granulation component 210, cutting component 220, and rounding component 230 work together to round the stirred material. This extrusion rounding granulator has a simple structure, high practicality, and can improve the rounding granulation efficiency of raw materials.
