Description

Technical Field

[0001] This technical solution relates to the field of filter washing and drying machine technology, and specifically refers to a self-cleaning filter washing and drying machine. Background Technology

[0002] The "filtration, washing and drying machine" is a multi-functional integrated chemical equipment, mainly used in the pharmaceutical, chemical, food, pesticide, and dye industries. Its biggest feature is that it integrates the three key operations of filtration, washing and drying, which traditionally require multiple pieces of equipment (such as filters, washing tanks and dryers), into a single closed device for continuous completion. Therefore, it is also known as a "three-in-one device".

[0003] In existing filter washing and drying machines, the filtration and washing processes require stirring the mixture of materials. During the stirring process, depending on the different characteristics of the materials, the stirring mechanism may mechanically compact the materials. When this happens, the materials will adhere to the blades used for stirring, which will cause material loss or contamination of other materials when they are processed again. Summary of the Invention

[0004] The purpose of this technical solution is to provide a self-cleaning filter washing and drying machine. By setting an air blowing mechanism on the stirring mechanism, the air blowing mechanism can blow air from the inside to the outside of the stirring part to clean the material adhering to the surface of the stirring part, thus solving the problem of material adhering to the stirring part.

[0005] The purpose of this technical solution is achieved as follows:

[0006] A self-cleaning filter washing and drying machine includes: a washing tank with an internal receiving chamber, the washing tank also having an inlet and an outlet; a stirring mechanism disposed on the washing tank and partially extending into the receiving chamber for stirring a mixture containing materials; a filtering mechanism disposed on the washing tank for filtering the mixture; a heating mechanism disposed on the washing tank for heating the mixture or drying the materials; and an air blowing mechanism disposed on the stirring mechanism for blowing air from the inside to the outside of the stirring section of the stirring mechanism to clean the materials adhering to the surface of the stirring section; wherein, the stirring mechanism includes a driving member and a stirring section disposed at its output end; the air blowing mechanism includes an air blowing source and an air blowing passage, the air blowing passage being opened inside the stirring section; the surface of the stirring section has a plurality of air outlets communicating with the air blowing passage.

[0007] Preferably, the stirring part includes a shaft and several blades disposed on the shaft; the blowing air path includes a main blowing air path opened on the shaft and blowing air chambers opened in the blades; the blowing air source delivers gas along the main blowing air path to each blowing air chamber, and then discharges it through the air outlet.

[0008] Preferably, the shape of the blowing chamber is adapted to the shape of the blade.

[0009] Preferably, the air outlet is frustum-shaped, with its inner diameter being larger than its outer diameter.

[0010] Preferably, the washing tank has an outer shell and an inner liner, with an installation space formed between the outer shell and the inner liner; the heating mechanism is disposed within the installation space, and the heating mechanism includes a plurality of heaters, all of which are arrayed within the installation space.

[0011] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0012] 1. The mixing mechanism designed in this technical solution has an air blowing passage inside the mixing part, and the surface of the mixing part has an air outlet that connects to the air blowing passage. The air blowing mechanism can blow air from inside the mixing part to the outside, and clean the surface of the mixing part by exhausting the air. By designing the size of the air outlet, the mixture can be prevented from entering the air blowing passage due to capillary action. The air blowing mechanism can achieve the function of cleaning the mixing part while mixing, without opening the washing tank.

[0013] 2. The air blowing path designed in this technical solution includes a main air blowing path and an air blowing chamber. The air blowing chamber is connected to multiple air outlets, which ensures that the air volume and air pressure of each air outlet are approximately the same. After any air outlet is covered by material, it can be cleaned immediately. Furthermore, by controlling the total air volume of the air source, a stable pressure can be maintained in the washing tank. Attached Figure Description

[0020] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 As shown, a self-cleaning filter washing and drying machine includes a washing tank 1, a stirring mechanism 5, a filtering mechanism, a heating mechanism, and an air blowing mechanism. The washing tank 1 includes a cylindrical part 21 and a conical part 22. The cylindrical part 21 and the conical part 22 can be integrally formed or welded together. The cylindrical part 21 is located above the conical part 22. The washing tank 1 is hollow to form a receiving chamber 2. The washing tank 1 also has a feed inlet 3 and a discharge outlet 4. During processing, the material can be added into the washing tank 1 first, and then a solvent can be injected for mixing. Alternatively, a mixture of materials can be added directly.

[0022] The stirring mechanism 5 is partially mounted on the washing tank 1 and partially extends into the receiving chamber 2. The stirring mechanism 5 is used to stir the mixture containing materials to fully dissolve or evenly mix the materials. The filtration mechanism is mounted in the washing tank 1 and is used to filter the mixture, allowing the solution containing impurities to flow out and leaving the desired material. The heating mechanism includes several heaters 20 for heating the mixture or drying the materials.

[0023] Specifically, such as Figure 2 and 3 As shown, the stirring mechanism 5 includes a driving component 8 and a stirring part 9. The driving component 8 can be a drive motor, and the stirring part 9 is located at the output end of the drive motor. The stirring part 9 includes a shaft 10 and several blades 11. In this embodiment, the blades 11 are paddle-shaped and formed on the periphery of the shaft 10. The air blowing mechanism includes an air blowing source 13 and an air blowing passage 14. The air blowing passage 14 includes a main air blowing passage 16 opened on the shaft 10 and air blowing chambers 17 opened in the blades 11. The main air blowing passage 16 is connected to several air blowing chambers 17. The air blowing source 13 sends air to each air blowing chamber 17 through the main air blowing passage 16 and then discharges it through the air outlet 15.

[0024] Because the paddle-shaped blade 11 has an arc, it will exert pressure on the mixture when stirring the mixture, causing the mixture to stick to the surface of the blade 11. The air outlet 15 on the surface of the blade 11 is connected to the air blowing chamber 17. The air outlet 15 is small, which can ensure that the mixture will not flow back into the air blowing chamber 17 due to capillary effect. The air blowing source 13 is located on the side of the stirring part 9 and rotates with the stirring part 9 when it works. The air blowing source 13 can be a pump body, and the pump body is connected to the main air blowing channel 16.

[0025] Furthermore, the shape of the blowing chamber 17 is adapted to the shape of the blade 11 to ensure that the air outlet 15 can cover most of the surface of the stirring part 9. The air outlet 15 has an air inlet and an air outlet. The air inlet is on one side connected to the blowing chamber 17, and the air outlet is on the surface of the stirring part 9. The inner diameter of the air inlet is larger than the inner diameter of the air outlet. This ensures that the airflow is pressurized during blowing, which can better clean the surface of the stirring part 9.

[0026] like Figure 1 As shown, the washing tank 1 has an outer shell 18 and an inner liner 19, with an installation space formed between the outer shell 18 and the inner liner 19. A second heating assembly is disposed in the installation space. The second heating assembly includes a plurality of heaters 20, all of which are arrayed in the installation space. The heaters 20 are used to heat the mixture or dry the material. The heaters 20 are disposed in the installation space to ensure their cleanliness and increase the heat transfer efficiency.

[0027] [Modification] The second heating assembly includes several heaters 20, all of which are disposed on the outer wall of the washing tank 1.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this technical solution. Those skilled in the art should understand that this technical solution is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this technical solution. Various changes and modifications can be made to this technical solution without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed technical solution.
