Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to an air cooling unit for a water-based paint mixer. Background Art

[0002] During the coatings processing process, a mixer is often required to stir the raw materials. A mixer is typically composed of a stirring blade, a stirring shaft, a shaft seal, and a motor. The motor is the core component of the mixer. It is powered by a power supply to drive the stirring blades to rotate, generating shear and extrusion forces to mix the various raw materials. The purpose is to break up the particles or dispersions in the coating and evenly distribute them in the solvent.

[0003] However, the high-speed rotation of the agitator shaft generates high temperatures, which dissipate outward, causing the surrounding temperature to become excessively high, seriously affecting the lifespan and operational safety of the equipment. Furthermore, because the shaft seal is made of plastic or rubber, it is prone to fatigue hardening over extended periods of operation, resulting in a decrease in sealing effectiveness. Existing agitators use water-cooled motors, and as the shaft seal ages, cooling water can easily leak into the reactor, diluting the material and affecting product quality. Utility Model Content

[0004] In order to effectively reduce the temperature of the stirring shaft during use and improve the reliability and safety of the equipment, the present application provides an air cooling unit for a water-based paint mixer.

[0005] In order to achieve the above objectives, this application adopts the following technical solutions:

[0006] A wind cooling unit for a water-based paint mixer comprises a reactor, a power assembly and an air cooling box. A mounting base is provided on the top of the reactor, and the power assembly is fixed to the top of the reactor via the mounting base. An output end of the power assembly is connected to a stirring shaft, and the stirring shaft extends into the interior of the reactor. The air cooling box is provided on one side of the reactor and is connected to the power assembly, and the power assembly is cooled by the air cooling box.

[0007] By adopting the above device, the air cooling box is connected to the power assembly, which can effectively cool the power assembly and reduce the failure rate caused by overheating of the power assembly. In addition, the cooling effect of the air cooling box can extend the service life of the power assembly, reduce material fatigue and damage caused by high temperature, and improve the reliability, safety and stability of the equipment. Compared with the existing water cooling method, this application can solve the water leakage problem and ensure that the quality of the coating product is not affected.

[0008] Preferably, a connecting pipe is provided on the top of the air cooling box, a heat dissipation cavity is provided inside the mounting seat, and the connecting pipe passes through the mounting seat and is connected to the heat dissipation cavity.

[0009] By adopting the above device, the cold air in the air cooling box enters the heat dissipation cavity through the connecting pipe, and then diffuses from the heat dissipation cavity into the mounting seat, thereby quickly cooling the power components in the mounting seat.

[0010] Preferably, the heat dissipation cavity is annular in shape, the heat dissipation cavity is closely attached to the inner wall of the mounting seat, and a filter plate is provided on the side of the heat dissipation cavity away from the inner wall of the mounting seat.

[0011] Preferably, the filter plate is integrally formed with dense holes.

[0012] By adopting this device, the annular heat dissipation cavity can increase the heat dissipation area, allowing the cool air to circulate more evenly within the mounting base, achieving more effective cooling. In addition, a filter plate is installed on the side of the heat dissipation cavity away from the inner wall of the mounting base to reduce the entry of dust and impurities into the heat dissipation cavity, keeping the heat dissipation cavity clean and improving cooling efficiency.

[0013] Preferably, the power assembly includes an electric motor, a reducer and a transmission shaft, the reducer is connected to the output end of the electric motor, and the transmission shaft is connected to the reducer.

[0014] Preferably, a coupling is provided on the side of the transmission shaft away from the reducer, and the coupling is connected to the stirring shaft.

[0015] By adopting the above device, the motor drives the stirring shaft to rotate, which can ensure efficient power transmission, reduce energy loss, and improve stirring efficiency. In addition, the transmission shaft and the stirring shaft are connected by a coupling, which improves the reliability of the entire transmission system.

[0016] Preferably, a seal is provided between the coupling and the stirring shaft.

[0017] By adopting the above device, the seal can effectively reduce the leakage of water-based paint or other liquids from the connection between the stirring shaft and the coupling, while ensuring the sealing of the reactor and keeping the working environment clean and safe.

[0018] Preferably, the mounting base is provided with two heat dissipation holes, and the two heat dissipation holes are symmetrically arranged.

[0019] By adopting the above device, the symmetrically arranged heat dissipation holes help to form a balanced air flow path, effectively increasing the heat dissipation area, so that the cooling air can flow evenly through the power component, thereby improving the cooling effect.

[0020] This application has the following beneficial effects:

[0021] 1. In this application, an air cooling box is connected to the power assembly, effectively cooling it and reducing the failure rate caused by overheating. Furthermore, the cooling effect of the air cooling box can extend the service life of the power assembly and reduce material fatigue and damage caused by high temperatures. Compared with existing water cooling methods, this application can solve the problem of water leakage and ensure that the quality of the coating product is not affected.

[0022] 2. In this application, the symmetrically arranged heat dissipation holes help to form a balanced air flow path, effectively increasing the heat dissipation area, so that the cooling air can flow evenly through the power components, thereby improving the cooling effect.

[0028] The following is combined with Figure 1-3 This application is described in further detail.

[0029] An air cooling unit for a water-based paint mixer, such as Figure 1-2 As shown, it includes a reactor 1, a power assembly 2 and an air cooling box 3. A mounting base 4 is provided on the top of the reactor 1. The mounting base 4 is cylindrical and fixed to the top of the reactor 1 by bolts. The mounting base 4 is mainly used to fix the power assembly 2 to ensure that the power assembly 2 does not loosen during operation. The power assembly 2 is fixed to the top of the reactor 1 by the mounting base 4. The output end of the power assembly 2 is connected to the stirring shaft 5, which extends into the interior of the reactor 1. The air cooling box 3 is provided on one side of the reactor 1 and is connected to the power assembly 2. The power assembly 2 is cooled by the air cooling box 3.

[0030] Specifically, such as Figure 1-2As shown, the power assembly 2 includes a motor 21, a speed reducer 22, and a transmission shaft 23. The motor 21 is the power source of the entire system, and is powered by a power supply. The speed reducer 22 is connected to the output end of the motor 21 to reduce the speed of the motor 21 and increase the torque to meet the rotation requirements of the stirring shaft 5. The transmission shaft 23 is connected to the speed reducer 22 and is responsible for transmitting power to the stirring shaft 5. A coupling 24 is provided between the transmission shaft 23 and the stirring shaft 5 to ensure efficient power transmission.

[0031] like Figure 1-3 As shown, to improve the sealing performance of reactor 1, a seal 25 is provided between coupling 24 and agitator shaft 5 to prevent leakage even during prolonged operation. Seal 25 can be made of rubber or plastic and effectively reduces leakage of water-based paint or other liquids from the connection between agitator shaft 5 and coupling 24, while ensuring the sealing performance of reactor 1 and maintaining a clean and safe working environment.

[0032] like Figure 1-3 As shown, the air cooling box 3 is located on one side of the reactor 1 and is primarily used to cool the power assembly 2. A fan and refrigerant circulation piping are provided within the air cooling box 3, and the fan draws cold air out of the air cooling box 3. A connecting pipe 31 is provided at the top of the air cooling box 3, and a heat dissipation cavity 41 is provided within the mounting base 4. The connecting pipe 31 passes through the mounting base 4 and connects to the heat dissipation cavity 41, thereby directing cold air into the mounting base 4 and cooling the power assembly 2 located therein. In this embodiment, the connecting pipe 31 can be made of a flexible material, such as a silicone tube or rubber tube, to reduce the effects of vibration.

[0033] like Figure 3 As shown, heat dissipation cavity 41 is annular in shape and closely adheres to the inner wall of mounting base 4. This fully utilizes the surface area of ​​mounting base 4, allowing cool air to evenly diffuse into the cavity and improve the cooling effect. A filter plate 42 is fixed to the side of heat dissipation cavity 41 away from the inner wall of mounting base 4. The filter plate 42 is integrally formed with dense holes to prevent dust and impurities from entering the heat dissipation cavity 41 and affecting the heat dissipation effect.

[0034] In addition, if Figure 1-3 As shown, two heat dissipation holes 43 are provided on the mounting base 4 , and the two heat dissipation holes 43 are symmetrically arranged. The two heat dissipation holes 43 are located above the heat dissipation cavity 41 , which can further enhance the heat dissipation effect.

[0035] Working principle: During operation, the cold air in the air-cooled box 3 enters the heat dissipation cavity 41 through the connecting pipe 31, and is then released from the holes on the filter plate 42 into the mounting base 4, cooling the stirring shaft 5 and the seal 25, effectively solving the high temperature problem generated by the stirring shaft 5 during rotation, improving the stability and safety of the equipment, reducing maintenance costs, and avoiding the risk of coolant leakage in the existing water cooling method, thereby ensuring product quality.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
