Description

Technical Field

[0001] This utility model relates to the field of antifreeze preparation, and in particular to a stirring and filtering device for preparing automotive antifreeze. Background Technology

[0002] Antifreeze is essentially a cooling medium with antifreeze properties. In cold weather, when a vehicle is parked, it can prevent the coolant from freezing due to low temperatures, thereby preventing the radiator from cracking and the engine cylinder block from freezing.

[0003] Currently, in the preparation process of automotive antifreeze, traditional stirring devices mostly adopt a static single-shaft stirring structure, which relies on a single stirring shaft rotating in a fixed container to complete the mixing. However, this type of device has defects. The shear force generated by traditional single-shaft stirring is limited, making it difficult to effectively break up the agglomeration of antifreeze raw materials (such as ethylene glycol, preservatives, defoamers, etc.), resulting in uneven dispersion of components, which in turn affects the key properties of antifreeze such as antifreeze and corrosion resistance. This is mainly due to the fact that static stirring relies only on axial flow, lacks multi-dimensional hybrid power, and the limited coverage of the stirring blades can easily lead to the formation of "dead zones" at the edge of the container, resulting in local accumulation of raw materials. Utility Model Content

[0004] In order to overcome the problem that traditional static single-shaft agitators, due to their limited shear force and reliance on axial flow, lack of multi-dimensional hybrid power, are prone to insufficient breaking up of raw material agglomeration, thus affecting the quality of antifreeze.

[0005] The technical solution of this utility model is as follows: a stirring and filtering device for preparing automotive antifreeze, comprising a supporting base and a supporting component fixed to its bottom. A vertical positioning plate is disposed on the upper surface of the supporting base. A drive module capable of outputting rotational power is disposed on the side end of the vertical positioning plate. The output end of the drive module is detachably connected to a U-shaped frame. A cylindrical filter container for holding antifreeze raw materials is disposed on the U-shaped frame. A locking mechanism for radially constraining the cylindrical filter container is disposed on the side end of the U-shaped frame. An axially extending stirring mechanism is disposed in the internal cavity of the cylindrical filter container. The power unit of the stirring mechanism is mounted on the U-shaped frame. A sealed feed port for injecting materials is opened at the top of the cylindrical filter container. A discharge channel with a valve is disposed on the circumferential position of the side wall of the cylindrical filter container. The drive module includes a rotating unit disposed on the side end of the vertical positioning plate and a transmission unit connected to the rotating unit. The rotating unit drives the U-shaped frame to rotate through the drive transmission unit.

[0006] Preferably, the rotating unit includes a bracket mounted on the side of the vertical positioning plate, a servo motor mounted on the bracket, a bearing seat mounted on the upper end of the bearing base, and a main shaft connected to the output shaft of the servo motor mounted inside the bearing seat.

[0007] Preferably, the transmission unit includes a rotating shaft mounted on a vertical positioning plate. One end of the rotating shaft is fixedly connected to the side wall of the U-shaped frame. A driven bevel gear is mounted on the outer wall of the other end of the rotating shaft, and a driving bevel gear is mounted on the outer wall of the main shaft. The driving bevel gear and the driven bevel gear are meshed together.

[0008] Preferably, the locking mechanism includes an extension arm mounted on a U-shaped frame, a screw mounted inside the extension arm, a knob mounted at one end of the screw, and a clamping plate mounted at the other end of the screw that is adapted to the outer diameter of the cylindrical filter container.

[0009] Preferably, the stirring mechanism includes a rotary motor mounted on a U-shaped frame, with a stirring shaft mounted on the output shaft of the rotary motor, and stirring blades mounted on the outer wall of the stirring shaft.

[0010] Preferably, the inner wall of the clamping plate facing the cylindrical filter container is provided with an anti-slip pad, and the anti-slip pad is provided with protrusions.

[0011] Preferably, the joint area between the vertical positioning plate and the bearing substrate is provided with a reinforcing rib, and the inclined extension path of the reinforcing rib forms a rigid connection with the bearing surface of the vertical positioning plate and the upper surface of the bearing substrate, respectively.

[0012] The beneficial effects of this utility model are:

[0013] Through the combined action of the drive module and the stirring mechanism, efficient and three-dimensional stirring of automotive antifreeze raw materials is achieved. Compared with the traditional static single-shaft stirring method, this design can break up the agglomeration in the raw materials more quickly, so that various components are fully and evenly dispersed, thereby improving the quality and performance of antifreeze. In addition, the U-shaped frame with detachable connection to the drive module greatly facilitates the maintenance and cleaning of the equipment and reduces the complexity of operation.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 - Figure 5This utility model provides an embodiment of a stirring and filtering device for preparing automotive antifreeze, comprising a supporting base 1 and a supporting member 2 fixed to its bottom. A vertical positioning plate 3 is disposed on the upper surface of the supporting base 1. A drive module capable of outputting rotational power is disposed on the side end of the vertical positioning plate 3. The output end of the drive module is detachably connected to a U-shaped frame 4. A cylindrical filter container 5 for holding antifreeze raw materials is disposed on the U-shaped frame 4. A locking mechanism for radially constraining the cylindrical filter container 5 is provided on the side end of the U-shaped frame 4. An axially extending stirring mechanism is disposed in the internal cavity of the cylindrical filter container 5. The power unit of the stirring mechanism is installed on the U-shaped frame 4. A sealed feed port 6 for injecting materials is opened at the top of the cylindrical filter container 5. A discharge channel 7 with a valve is disposed on the circumferential position of the side wall of the cylindrical filter container 5.The drive module includes a rotating unit mounted on the side of the vertical positioning plate 3 and a transmission unit connected to the rotating unit. The rotating unit drives the U-shaped frame 4 to rotate through the transmission unit. The supporting base 1 is the basic support platform for the entire stirring and filtering device, made of high-strength, corrosion-resistant metal material. The support member 2 is used to stably support the entire device on the ground. The support member 2 can be a sturdy metal rod structure. The vertical positioning plate 3 provides the installation reference and positioning function for the drive module. The vertical positioning plate 3 ensures that it remains perpendicular to the supporting base 1, thereby ensuring that the drive module can accurately output rotational power after installation, enabling the U-shaped frame 4 and the cylindrical filter container 5 to rotate. The rotating unit can rotate along a predetermined axis, providing a reliable power source for the subsequent transmission unit. The transmission unit, connected to the rotating unit, transmits the rotational power output by the rotating unit to the U-shaped frame 4, thereby driving the U-shaped frame 4 to rotate. The U-shaped frame 4 supports the cylindrical filter container 5 and rotates under the drive of the drive module. The U-shaped frame 4 is made of high-strength metal material, capable of bearing the weight of the cylindrical filter container 5 and its internal antifreeze material. The detachable connection method facilitates the installation, disassembly, and maintenance of the cylindrical filter container 5. When cleaning or replacing the filter screen is required, the U-shaped frame 4 can be easily connected to the drive module. Block separation improves work efficiency. A locking mechanism radially constrains the cylindrical filter container 5 to prevent it from shaking during rotation. The cylindrical filter container 5 holds the antifreeze material and performs a stirring function during device operation. Its internal cavity provides space for the antifreeze material and is made of corrosion-resistant, high-strength material to prevent corrosion. The power unit of the stirring mechanism is mounted on the U-shaped frame 4, providing stirring power. The stirring component is located inside the cylindrical filter container 5 and connected to the power unit, rotating and stirring under the drive of the power unit. When the stirring component rotates, it can move the antifreeze material within the cylindrical filter container 5. The internal flow and mixing break up the agglomeration of raw materials, ensuring full dispersion of various components and improving the quality and performance of the antifreeze. The inlet 6 is equipped with a sealing cap, which is sealed to the inlet 6 using sealing gaskets or other sealing elements. When raw materials need to be injected, the sealing cap is opened; after injection, the sealing cap is closed, ensuring a good seal. The outlet channel 7 discharges the stirred antifreeze from the cylindrical filter container 5. The valve design controls the discharge flow rate and time. Furthermore, the outlet channel 7 is equipped with a filtration structure (such as a filter screen or filter element). During the discharge process, impurities are trapped by the filtration structure, achieving a filtration function and yielding pure antifreeze.

[0022] Please see Figure 3In this embodiment, the rotating unit includes a bracket 8 mounted on the side of the vertical positioning plate 3, a servo motor 9 mounted on the bracket 8, a bearing seat 10 mounted on the upper end of the bearing base 1, and a main shaft 11 connected to the output shaft of the servo motor 9 mounted inside the bearing seat 10. The transmission unit includes a rotating shaft 12 mounted on the vertical positioning plate 3, one end of the rotating shaft 12 being fixedly connected to the side wall of the U-shaped frame 4, and a driven bevel gear 13 mounted on the outer wall of the other end of the rotating shaft 12. A driving bevel gear 14 is mounted on the outer wall of the main shaft 11, and the driving bevel gear 14 meshes with the driven bevel gear 13. The bracket 8 provides a stable mounting platform for the servo motor 9. The bearing housing 10 is a support and positioning component for the spindle 11. It contains high-precision bearings to ensure that the spindle 11 maintains a high degree of coaxiality and stability during rotation. As a power transmission component, the spindle 11 transmits the rotational power output by the servo motor 9 to the drive bevel gear 14. When the drive bevel gear 14 rotates under the drive of the spindle 11, it transmits the rotational motion to the rotating shaft 12 through meshing with the driven bevel gear 13, thereby driving the U-shaped frame 4 to achieve synchronous rotation.

[0023] Please see Figure 1 , Figure 4 and Figure 5In this embodiment, the locking mechanism includes an extension arm 15 mounted on the U-shaped frame 4, a screw 16 disposed within the extension arm 15, a knob 17 disposed at one end of the screw 16, and a clamping plate 18 adapted to the outer diameter of the cylindrical filter container 5 disposed at the other end of the screw 16. The stirring mechanism includes a rotary motor 19 mounted on the U-shaped frame 4, a stirring shaft 20 disposed on the output shaft of the rotary motor 19, stirring blades 21 disposed on the outer wall of the stirring shaft 20, and anti-slip features disposed on the inner wall of the clamping plate 18 facing the cylindrical filter container 5. The pad and anti-slip pad are provided with protrusions. The joint area between the vertical positioning plate 3 and the bearing base 1 is provided with reinforcing ribs 22. The inclined extension path of the reinforcing ribs 22 forms a rigid connection with the bearing surface of the vertical positioning plate 3 and the upper surface of the bearing base 1, respectively. The extension arm 15 provides installation space and support structure for the screw 16 and the clamping plate 18. The screw 16 is threaded inside the extension arm 15. When the knob 17 is turned, the screw 16 can move axially within the extension arm 15, thereby controlling the movement of the clamping plate 18. The system enables locking or unlocking of the cylindrical filter container 5. The clamping plate 18 is used to directly apply clamping force to the cylindrical filter container 5 to prevent it from shaking during rotation. The anti-slip pad is used to increase the friction between the clamping plate 18 and the cylindrical filter container 5, further improving the reliability of locking. The rotary motor 19 is mounted on the U-shaped frame 4 and is the power source of the stirring mechanism. The stirring shaft 20 transmits the rotational power output by the rotary motor 19 to the stirring blades 21. When the stirring shaft 20 rotates, the stirring blades 21 drive the antifreeze raw material to flow and mix in the cylindrical filter container 5, breaking the agglomeration in the raw material and making various components fully dispersed to achieve the purpose of uniform stirring. At the same time, the driving module makes the stirring efficiency better. The reinforcing rib 22 is used to enhance the connection strength between the vertical positioning plate 3 and the supporting base 1 and the stability of the overall structure. The reinforcing rib 22 can effectively disperse and transmit these forces, reduce stress concentration in the joint area, and prevent deformation or cracking between the vertical positioning plate 3 and the supporting base 1.

[0024] Working principle: First, the automotive antifreeze raw material is injected into the cylindrical filter container 5 through the sealed inlet 6. The sealing cover is closed and the seal is ensured to be good. Then, the servo motor 9 in the rotating unit is started. The output shaft of the servo motor 9 drives the main shaft 11 to rotate. The driving bevel gear 14 on the main shaft 11 meshes with the driven bevel gear 13 in the transmission unit, transmitting the rotational power to the rotating shaft 12, which in turn drives the U-shaped frame 4 and the cylindrical filter container 5 it carries to rotate along the predetermined axis.

[0025] At the same time, the rotary motor 19 in the stirring mechanism starts, and the output shaft drives the stirring shaft 20 to rotate. The stirring blades 21 on the stirring shaft 20 generate strong flow and mixing in the cylindrical filter container 5, breaking the agglomeration in the raw materials, so that the various components are fully dispersed and uniform stirring is achieved.

[0026] During the stirring process, the locking mechanism ensures that the cylindrical filter container 5 is stably fixed on the U-shaped frame 4 to prevent it from shaking. After the stirring is completed, the discharge flow rate and time are controlled by the valve on the discharge channel 7 to discharge the pure antifreeze that has been stirred and filtered out of the cylindrical filter container 5. During the discharge process, the filter structure in the discharge channel 7 intercepts impurities, realizes the filtration function, and obtains high-quality antifreeze.

[0027] Through the above steps, the combined action of the drive module and the stirring mechanism achieves efficient three-dimensional stirring of automotive antifreeze raw materials, rapidly breaking up agglomerates, dispersing the components evenly, and improving the quality of antifreeze. At the same time, the U-shaped frame 4, which is detachably connected to the drive module, facilitates maintenance and solves the problem that traditional static single-shaft stirring devices, due to limited shear force and reliance on axial flow, lack multi-dimensional hybrid power, are prone to insufficient breaking up of raw material agglomerates, thus affecting the quality of antifreeze.
