Description

Technical Field

[0001] This utility model relates to the field of additive processing technology, specifically to an additive filtration and stirring device. Background Technology

[0002] In the fields of chemical engineering, coatings, food processing, and pharmaceutical intermediate production, additives are key auxiliary materials for improving product performance and increasing production efficiency. Their pretreatment process directly determines the quality stability and production continuity of subsequent products. Currently, the industry largely relies on traditional filtration and stirring devices for additive processing. While these devices can achieve basic stirring and filtration functions, they still face many technical bottlenecks in practical applications, making it difficult to meet the demands of high-precision and high-efficiency production. Specific problems are as follows:

[0003] Existing additive filtration and stirring devices mostly use unidirectional rotating stirring components with smooth internal structures. During stirring, additives are prone to aggregate towards the chamber walls due to centrifugal force, or dead zones may form at the bottom or around the shaft, leading to agglomeration of functional particles. Furthermore, most existing devices employ a step-by-step processing mode of stirring followed by filtration, or, although integrated, the stirring and filtration actions are independent: the stirring component only handles additive mixing, while filtration relies on the filter screen's own permeation or external low-pressure drive. This makes it easy for additives to stratify after stirring and settle, resulting in uneven composition when transferred to the filtration stage. Traditional filtration and stirring devices often have fixed or difficult-to-disassemble stirring chambers and filter cartridges. After processing different types of additives, manual disassembly is required for cleaning the inner walls and filter screen, a time-consuming and labor-intensive process that can leave residues and lead to cross-contamination between different additives. Utility Model Content

[0004] The purpose of this invention is to provide an additive filtration and stirring device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an additive filtration and stirring device, comprising an outer cylinder and an inner cylinder, wherein the inner cylinder is horizontally arranged inside the outer cylinder via a bearing seat, the surface of the inner cylinder is uniformly provided with filter holes, and the inner wall of the inner cylinder is uniformly distributed with protrusions in an annular shape, a servo motor is installed at one end of the outer cylinder, the output end of the servo motor extends into the interior of the inner cylinder and is connected to a main shaft, and stirring blades are uniformly installed on the main shaft, a connecting rod is provided on the main shaft between adjacent stirring blades, and a second protrusion is provided at the top of the connecting rod;

[0006] A turbine gear ring is provided at one end of the outer side of the inner cylinder, and a rotary motor is provided on the outer wall of the outer cylinder at the position corresponding to the turbine gear ring. The output end of the rotary motor extends to the inner side of the inner cylinder and is connected to a worm gear that meshes with the turbine gear ring.

[0007] Preferably, a feed hopper is installed at the end of the outer cylinder away from the servo motor, a metal filter screen is provided on the inner side of the feed hopper, and the output end of the feed hopper extends into the interior of the inner cylinder. One end of the inner cylinder is provided with a through hole for the output end of the feed hopper to be inserted.

[0008] Preferably, the bottom of the outer cylinder is provided with parallel material discharge ports, and the bottom of the outer cylinder outside the material discharge ports is provided with discharge pipes. The material discharge ports are in the shape of an inverted trapezoidal funnel. The side wall of the outer cylinder is also equipped with a controller.

[0009] Preferably, a U-shaped pipe is provided at the top of the outer cylinder, and an inlet pipe connected to an external water source is provided at the input end of the U-shaped pipe. Both ends of the U-shaped pipe extend to the top of the inner side of the outer cylinder and are connected to a distribution pipe.

[0010] Preferably, the main shaft and the inner cylinder rotate in opposite directions.

[0011] Preferably, the axes of protrusion one and protrusion two coincide, and when the connecting rod connecting protrusion two rotates with the main shaft, protrusion two intermittently collides with protrusion one.

[0012] This utility model relates to an additive filtration and stirring device, which has significant advantages over the prior art, as detailed below:

[0013] 1. This device uses a metal filter screen inside the feed hopper to filter large particles of impurities and protect the subsequent precision filter screen. The stirring blades on the main shaft inside the inner cylinder, combined with the filter holes evenly distributed on the surface, can effectively stir and filter the additives, thereby improving the filtration efficiency. In addition, the annularly distributed protrusions on the inner wall of the inner cylinder and the protrusions on the top of the connecting rod collide with each other, which can further break and disperse the agglomerates in the additives, ensuring a more refined filtration effect.

[0014] 2. The evenly mounted stirring blades on the main shaft, driven by a servo motor, enable efficient stirring of the additives, ensuring uniform mixing during the process. The design of the main shaft and the inner cylinder rotating in opposite directions further enhances the uniformity of stirring and avoids dead zones caused by unidirectional rotation. The design of the U-shaped tube and distribution pipe, along with the automatic cleaning of the device's interior via flushing nozzles, ensures the long-term stable operation of the equipment.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figure 1-4 One embodiment of this utility model is an additive filtration and stirring device, which includes an outer cylinder 1 and an inner cylinder 6. The inner cylinder 6 is horizontally arranged inside the outer cylinder 1 through a bearing seat 2.

[0022] A feed hopper 9 is installed at the end of the outer cylinder 1 away from the servo motor 3. A metal filter screen 21 is provided on the inner side of the feed hopper 9, and the output end of the feed hopper 9 extends into the interior of the inner cylinder 6. A through hole is provided at one end of the inner cylinder 6 for the output end of the feed hopper 9 to be inserted.

[0023] The bottom of the outer cylinder 1 is provided with parallel material discharge ports 13. The bottom of the outer cylinder 1 outside the material discharge ports 13 is provided with discharge pipes 12. The material discharge ports 13 are in the shape of an inverted trapezoidal funnel. The side wall of the outer cylinder 1 is also equipped with a controller 20.

[0024] A feed hopper 9 is installed at the end of the outer cylinder 1 furthest from the servo motor 3. A metal filter 21 is provided on the inner side of the feed hopper 9 to filter the material entering the inner cylinder 6 and prevent impurities from entering. The output end of the feed hopper 9 extends into the interior of the inner cylinder 6 to ensure that the material can enter the inner cylinder 6 smoothly. One end of the inner cylinder 6 is provided with a through hole for the insertion of the output end of the feed hopper 9. The diameter of the through hole is slightly larger than the diameter of the output end of the feed hopper 9 to ensure that the feed hopper 9 can be tightly inserted.

[0025] The bottom of the outer cylinder 1 is provided with parallel material discharge ports 13. The material discharge ports 13 have an inverted trapezoidal funnel-shaped structure, which helps the material to flow out smoothly and avoids blockage. The bottom of the outer cylinder 1 outside the material discharge ports 13 is provided with discharge pipes 12, which are used to discharge the filtered material from the device.

[0026] A controller 20 is also installed on the side wall of the outer cylinder 1. The controller 20 is used to control the operation of the entire device, including the rotation speed of the inner cylinder 6, the opening and closing of the feed hopper 9, etc. A servo motor 3 is installed at one end near the inner cylinder 6 and drives the inner cylinder 6 to rotate through a transmission device.

[0027] The inner cylinder 6 has filter holes 22 evenly arranged on its surface, and the inner wall of the inner cylinder 6 has protrusions 5 evenly distributed in a ring. One end of the outer cylinder 1 is equipped with a servo motor 3. The output end of the servo motor 3 extends into the inner cylinder 6 and is connected to a main shaft 8. Stirring blades 4 are evenly arranged on the main shaft 8. A connecting rod 11 is arranged on the main shaft 8 between adjacent stirring blades 4. The top of the connecting rod 11 is equipped with a protrusion 7.

[0028] The inner cylinder 6 is located inside the outer cylinder 1 and is also a cylindrical structure, but its diameter is smaller than that of the outer cylinder 1, so as to form an annular space between the two. The surface of the inner cylinder 6 is uniformly provided with filter holes 22. The diameter and distribution density of these filter holes 22 are designed according to the actual application requirements to ensure that the material can be effectively filtered during the mixing process.

[0029] The inner wall of the inner cylinder 6 is uniformly distributed with protrusions 5 in a ring. The height and spacing of these protrusions 5 are precisely calculated to enhance the disturbance effect of the material during the mixing process and improve the mixing efficiency.

[0030] The servo motor 3 is installed at one end of the outer cylinder 1, and its output end extends into the interior of the inner cylinder 6 and is connected to the main shaft 8. The selection of the servo motor 3 should take into account its torque and speed to ensure that it can provide sufficient power to drive the main shaft 8 and the stirring blades 4.

[0031] The main shaft 8 has a cylindrical structure and can be made of high-strength alloy steel to ensure stability and durability during high-speed rotation. Stirring blades 4 are evenly mounted on the main shaft 8, and the shape and angle of the stirring blades 4 are designed to facilitate thorough mixing of the materials.

[0032] A connecting rod 11 is provided on the main shaft 8 between adjacent stirring blades 4. The length and material of the connecting rod 11 should be selected according to the actual application requirements to ensure its stability and durability during high-speed rotation. The top of the connecting rod 11 is provided with a second protrusion 7, which cooperates with the first protrusion 5 on the inner wall of the inner cylinder 6 to further enhance the disturbance effect of the material during the mixing process.

[0033] The main shaft 8 and the inner cylinder 6 rotate in opposite directions.

[0034] Specifically, when the servo motor 3 drives the main shaft 8 to rotate clockwise, the inner cylinder 6 rotates counterclockwise. This reverse rotation design can significantly improve the mixing efficiency of materials, creating strong convection and shearing effects in the annular space between the inner and outer cylinders, thereby achieving uniform mixing.

[0035] The axes of protrusion 5 and protrusion 7 coincide, and when the connecting rod 11 connecting protrusion 7 rotates with the main shaft 8, protrusion 7 intermittently collides with protrusion 5.

[0036] The protrusion 5 is a cylindrical structure with its axis coinciding with the axis of the main shaft 8, ensuring that the protrusion 5 maintains a fixed position and orientation when the main shaft 8 rotates. The protrusion 5 is made of high-strength alloy steel to ensure that it is not easily deformed during impact.

[0037] Protrusion 2 7 is also a cylindrical structure, but its diameter is slightly smaller than that of protrusion 1 5. Protrusion 2 7 is connected to the main shaft 8 via connecting rod 11, and its axis coincides with the axis of protrusion 1 5. Protrusion 2 7 is also made of high-strength alloy steel to ensure its good durability during impact.

[0038] The connecting rod 11 is a rigid member, and its length is designed according to specific application requirements to ensure that the second protrusion 7 can intermittently impact the first protrusion 5 when the main shaft 8 rotates. The connecting rod 11 is made of high-strength aluminum alloy, which ensures both strength and reduces weight.

[0039] When the main shaft 8 starts to rotate, the connecting rod 11 drives the second protrusion 7 to rotate around the axis of the main shaft 8. Since the first protrusion 5 is fixed on the main shaft 8, its position remains unchanged.

[0040] As the spindle 8 continues to rotate, protrusion 2 7, driven by the connecting rod 11, intermittently collides with protrusion 1 5. The frequency and force of the collision depend on the rotational speed of the spindle 8 and the mass of protrusion 2 7.

[0041] During each impact, a certain impact force is generated at the moment when protrusion 2 7 contacts protrusion 1 5, which causes the inner cylinder 6 to vibrate.

[0042] A turbine gear ring 10 is provided at one end of the outer side of the inner cylinder 6, and a rotary motor 19 is provided on the outer wall of the outer cylinder 1 at the position corresponding to the turbine gear ring 10. The output end of the rotary motor 19 extends to the inner side of the inner cylinder 6 and is connected to a worm gear 18 that meshes with the turbine gear ring 10.

[0043] Worm gear ring 10: The worm gear ring 10 is fixed to the outside of the inner cylinder 6. It is made of high-strength alloy steel, which has good wear resistance and fatigue resistance. The tooth profile of the worm gear ring 10 is designed as a special helical shape to optimize the meshing effect with the worm 18.

[0044] Rotary motor 19: The rotary motor 19 is installed on the outer wall of the outer cylinder 1, corresponding to the position of the turbine gear ring 10. The rotary motor 19 is a high-efficiency permanent magnet motor, which has the characteristics of large output torque, low energy consumption, and smooth operation. The output end of the rotary motor 19 extends to the inner side of the inner cylinder 6 through bearings and sealing devices.

[0045] Worm 18: Worm 18 is connected to the output end of the rotary motor 19 and meshes with the worm gear ring 10. Worm 18 is made of high-strength alloy steel with a hardened surface to improve its wear resistance. The helix angle of worm 18 matches the tooth profile of the worm gear ring 10 to ensure maximum transmission efficiency.

[0046] A U-shaped pipe 15 is provided at the top of the outer cylinder 1. The inlet end of the U-shaped pipe 15 is provided with a water inlet pipe 16 connected to an external water source. Both ends of the U-shaped pipe 15 extend to the top of the inner side of the outer cylinder 1 and are connected to a distribution pipe 14. Flushing nozzles 17 are evenly installed at the bottom of the distribution pipe 14.

[0047] U-shaped pipe 15 is installed at the top of the outer cylinder 1 and is made of high-pressure resistant plastic or metal material. The inlet end of the U-shaped pipe 15 is connected to a water inlet pipe 16, and the other end of the water inlet pipe 16 is connected to an external water source to ensure that the water source can smoothly enter the U-shaped pipe 15. Both ends of the U-shaped pipe 15 extend to the top of the inner side of the outer cylinder 1 and are fixed by flange connection to ensure its stability and sealing.

[0048] The inlet pipe 16 is made of corrosion-resistant PVC or stainless steel. One end is connected to the input end of the U-shaped pipe 15, and the other end is connected to the external water source by thread or snap.

[0049] The two ends of the distribution pipe 14 are connected to the two ends of the U-shaped pipe 15, forming a closed water flow channel. The distribution pipe 14 is made of high-pressure resistant plastic or metal material, and multiple flushing nozzles 17 are evenly installed at its bottom. The installation position and angle of the distribution pipe 14 are precisely designed to ensure that the water flow can be evenly distributed to all parts of the outer cylinder 1.

[0050] The flushing nozzles 17 are evenly distributed at the bottom of the distribution pipe 14 and are made of high-pressure resistant plastic or metal. Each flushing nozzle 17 has an adjustable nozzle angle to ensure that the water flow is sprayed at the optimal angle onto the inner wall of the outer cylinder 1, achieving a highly efficient flushing effect. The number and distribution of the flushing nozzles 17 are optimized according to the size and shape of the outer cylinder 1 to maximize the flushing effect.

[0051] In this embodiment, the additive to be processed is poured into the feed hopper 9 at the end of the outer cylinder 1 furthest from the servo motor 3. Under the action of gravity, the additive flows through the metal filter 21 inside the feed hopper 9. The metal filter 21 pre-filters large particulate impurities in the additive, preventing them from entering the inner cylinder 6. The filtered additive then enters the inner cylinder 6 through a pre-set through-hole at one end of the inner cylinder 6 via the output end of the feed hopper 9, completing the feeding process.

[0052] The servo motor 3 and the rotary motor 19 are started by the controller 20. The servo motor 3 drives the main shaft 8, which extends into the inner cylinder 6, to rotate. The stirring blades 4, which are evenly installed on the main shaft 8, rotate with the main shaft 8 to stir and mix the additives that enter the inner cylinder 6, breaking the static stratification state of the additives. At the same time, the connecting rod 11 on the main shaft 8 between adjacent stirring blades 4 drives the second protrusion 7 at the top to rotate around the main shaft 8. Since the first protrusion 5 (uniformly distributed in a ring on the inner wall of the inner cylinder 6) and the second protrusion 7 coincide on the axis, the second protrusion 7 will intermittently collide with the first protrusion 5 when it rotates with the main shaft 8. The impact force generated by the collision causes the inner cylinder 6 to vibrate, which causes the agglomerates in the additives inside the inner cylinder 6 to break and disperse.

[0053] At the same time, the rotary motor 19 drives the worm gear 18 to rotate. The worm gear 18 meshes with the turbine gear ring 10 on the outer side of the inner cylinder 6, driving the inner cylinder 6 to rotate horizontally along the bearing seat 2 (in the opposite direction to the main shaft 8). Under the dual action of rotation and vibration, the filter holes 22 uniformly arranged on the surface of the inner cylinder 6 allow the qualified components in the uniformly dispersed additive to penetrate through the filter holes 22 and enter the annular space between the outer cylinder 1 and the inner cylinder 6, thereby achieving filtration.

[0054] The filtered additives that enter the annular space between the outer cylinder 1 and the inner cylinder 6 flow downwards under the action of gravity and collect at the discharge port 13 arranged in parallel at the bottom of the outer cylinder 1 (the inverted trapezoidal funnel structure can avoid the accumulation and blockage of additives). Then, they are discharged through the discharge pipe 12 at the bottom of the outer cylinder 1 outside the discharge port 13 and collected into the external finished product container, thus completing the filtration treatment of the additives.

[0055] When a batch of additives is processed or a different type of additive needs to be replaced, the servo motor 3 and rotary motor 19 are shut off via controller 20, stopping the stirring and filtering operations. Then, the external water source is turned on, and the water enters the U-shaped pipe 15 at the top of the outer cylinder 1 through the inlet pipe 16. The U-shaped pipe 15 diverts the water flow to distribution pipes 14 extending to the top of the inner side of the outer cylinder 1 at both ends. The flushing nozzles 17, evenly installed at the bottom of the distribution pipes 14, spray the water evenly onto the inner wall of the outer cylinder 1, the outer wall of the inner cylinder 6, and the surface of the stirring blades 4, flushing away any residual additives inside the device. The wastewater generated during flushing is also discharged through the discharge port 13 and the outlet pipe 12. The water source is shut off after flushing is complete.
