Description

Technical Field

[0001] This application relates to the field of food processing technology, specifically to a powder washing tank. Background Technology

[0002] Currently, traditional powder cleaning equipment mostly uses a method of placing a filter screen bucket inside the cleaning tank for cleaning operations. During the cleaning process, the powder is placed inside the filter screen bucket, and the material is fed into the filter screen bucket for cleaning. This method uses an open structure, and the filter screen bucket needs to be manually removed after cleaning is completed.

[0003] When the filter screen barrel cleaning equipment is stirring and rotating, it also causes the filter screen barrel to rotate relative to it, resulting in incomplete cleaning of the powder and uneven cleaning effect. This is especially true for powders that are highly viscous or have fine particles, which will adhere to the inner wall of the filter screen barrel, clogging it. This requires long soaking times and multiple cleanings to achieve the desired effect, reducing production efficiency. The bottom and corners of the filter screen barrel are prone to forming cleaning dead zones, causing some powders to not be fully cleaned, which affects the quality of the final product. Summary of the Invention

[0004] The technical problem to be solved by this application is to overcome the existing defects and provide a powder washing tank that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a powder washing tank, comprising a main tank body, a flow guide cavity provided at the lower end of the main tank body, the flow guide cavity being composed of a first flow guide plate and a second flow guide plate, both the first and second flow guide plates adopting a conical structure, and the two conical structures being arranged opposite each other, and a through hole provided at the coaxial line of the two for installing a powder discharge guide pipe, a return water connection pipe provided at the flow guide cavity, the first flow guide plate being densely covered with filter screen holes for water discharge, a support plate provided at the upper end of the main tank body, a drive motor provided on the support plate, the output end of the drive motor being connected to a main rotating shaft, and the main rotating shaft extending outward to form a stirring shaft.

[0006] As a preferred technical solution of this application, both sides of the support plate are provided with flip plates, and the flip plates are provided with handles.

[0007] As a preferred technical solution of this application, the support plate is provided with pipe flanges.

[0008] As a preferred technical solution of this application, a level gauge is provided on the outside of the main tank.

[0009] As a preferred technical solution of this application, an outer ring is provided at the lower end of the main tank, a connecting support is provided on the outer ring, and a weighing assembly is installed on the connecting support by fasteners.

[0010] As a preferred technical solution of this application, the pore size of the filter screen is 0.5-2.0 mm, and the filter screen pores are uniformly distributed on the first guide plate.

[0011] Compared with the prior art, the beneficial effects of this application are as follows: This application directly stirs the powder in the main tank through the stirring shaft, so that the powder and the cleaning water are fully mixed, accelerating the separation of impurities and effectively improving the cleaning efficiency and uniformity. It is especially suitable for cleaning powders with strong viscosity or fine particles. The first guide plate with filter screen holes is set in the guide cavity of this application. The powder is driven to rotate in the main tank by the stirring shaft, which can avoid adhering to the filter screen holes. It can achieve efficient solid-liquid separation, ensuring that the cleaning water is discharged smoothly while effectively intercepting powder particles to prevent them from being lost with the water flow, thus ensuring product quality and resource utilization. The conical structure of the first guide plate and the second guide plate arranged opposite to each other creates a gradually narrowing-expanding guide channel, which guides the powder and cleaning water to flow smoothly, reducing accumulation and retention, fundamentally avoiding the generation of cleaning dead corners and improving the overall cleaning quality.

Detailed Implementation

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0018] Please see Figure 1-4This application provides a technical solution: a powder washing tank, including a main tank body 4, the lower end of the main tank body 4 is provided with a flow guiding cavity, the flow guiding cavity is composed of a first flow guiding plate 11 and a second flow guiding plate 12, both the first flow guiding plate 11 and the second flow guiding plate 12 adopt a conical structure, and the two conical structures are arranged opposite to each other.

[0019] The main tank 4 is the main container of the washing tank, used to hold the powder to be washed and the washing water. Its lower end is provided with a guide cavity structure, which serves as the outlet channel for the material and water flow. The guide cavity is an internal structure composed of two conical guide plates located at the bottom of the main tank 4. It plays a role in guiding the flow of materials, controlling the water flow path, and improving drainage efficiency. The first guide plate 11 has a conical structure with densely distributed filter mesh holes on its surface. It achieves solid-liquid separation during drainage. The filter mesh holes allow water to pass through while intercepting powder particles to prevent the powder from being lost with the wastewater, thus playing a preliminary role in concentrating the materials. The second guide plate 12 is also a conical structure and is arranged opposite to the first guide plate 11. It assists the first guide plate 11 in forming a guide channel for discharging wastewater.

[0020] Both have a through hole at their coaxial axis for installing the powder discharge guide pipe 14, and a return water connection pipe 6 is provided at the flow guide cavity.

[0021] Located at the center alignment of the two conical guide plates, a channel is formed through the bottom of the main tank 4, providing an installation position for the guide pipe 14. The guide pipe 14 is a cylindrical pipe that passes through the through hole and extends to the outside of the washing tank, serving as a powder discharge channel to transport the washed powder to the next process or collection container. It is equipped with valves to realize the start and stop control of the discharge process.

[0022] The return water connection pipe 6 is located in the side wall area of ​​the guide cavity and is connected to the circulating water treatment device. The filtered cleaning wastewater is discharged and connected to the filtration and purification equipment to realize the recycling and reuse of water resources, reduce sewage discharge, and improve environmental protection performance.

[0023] The first guide plate 11 is densely covered with filter screen holes for water outlet.

[0024] A support plate is provided on the upper end of the main tank 4, and a drive motor 1 is provided on the support plate. The output end of the drive motor 1 is connected to a main rotating shaft 10, and the main rotating shaft 10 extends outward to form a stirring shaft 13.

[0025] A support plate is installed on the top of the main tank 4. It serves as a load-bearing platform for the drive motor 1 and the main shaft 10, providing stability and rigidity to the top structure. The drive motor 1 is a three-phase AC variable frequency motor or servo motor, and its speed can be adjusted according to process requirements to ensure sufficient torque and stability during the stirring process, providing a power source to drive the main shaft 10 and the stirring shaft 13 to rotate. The main shaft 10 vertically penetrates the top cover of the main tank 4 and is connected by a coupling. The stirring shaft 13 is arranged horizontally or inclined, directly participating in the stirring and cleaning process of the powder. The stirring blades fully agitate and mix the powder, improving cleaning efficiency; promoting uniform contact between the material and water, and accelerating the separation of impurities.

[0026] Furthermore, both sides of the support plate are provided with flaps 3, and handles 9 are provided on the flaps 3.

[0027] The flap 3 is a rotatable cover plate installed on both sides of the support plate to prevent dust, moisture or foreign objects from entering the equipment. It provides a maintenance passage and can be opened for inspection or replacement of parts when maintenance is required. The handle 9 is a handle device fixed on the outside of the flap 3, which makes it easy for operators to open and close the flap 3, improves the convenience of operation, facilitates quick opening and closing, enhances safety, and avoids scratches or accidental contact caused by bare hands.

[0028] Furthermore, the support plate is provided with a pipe flange 2.

[0029] Furthermore, a level gauge 15 is provided on the outside of the main tank 4.

[0030] The level gauge 15 is usually installed on the outer wall of the main tank 4 to monitor the liquid level in the tank in real time. During the powder cleaning process, the level gauge 15 can be used to intuitively understand the changes in the water level inside the main tank, preventing overflow due to excessively high liquid level or affecting the cleaning effect due to excessively low liquid level.

[0031] Furthermore, an outer ring 8 is provided at the lower end of the main tank 4, and a connecting support 5 is provided on the outer ring 8. The weighing assembly 7 is installed on the connecting support 5 by fasteners.

[0032] Furthermore, the pore size of the filter screen is 0.5-2.0 mm, and the filter screen pores are uniformly distributed on the first guide plate 11.

[0033] In use: Start the weighing group 7, record the initial material weight, connect the pipe through the flange 2, add the water-powder mixture to be cleaned to the main tank 4, observe the level gauge 15 to control the water volume within the set range to prevent overflow, start the drive motor 1 to drive the main shaft 10 to rotate, which in turn drives the stirring shaft 13 to fully stir the powder. During the stirring process, the powder and water are fully mixed, and impurities are separated and moved downwards with the water flow. Control the stirring time according to the type of powder and the degree of contamination. The motor speed can be adjusted through the frequency converter to adapt to different cleaning intensity requirements. Turn off the stirring motor. The machine waits for the powder to settle, then opens the drain valve on the return water connection pipe 6, allowing the wastewater to be filtered through the filter screen of the first guide plate 11 and discharged into the circulating water treatment system. The filter screen effectively intercepts powder particles, preventing them from being lost with the water. During the drainage process, the liquid level gauge 15 is continuously observed to ensure that the water is drained but not run dry. The above operation is repeated to clean the material. After the above operation is repeated and the cleaning is completed, the discharge valve at the lower end of the guide pipe 14 is opened. The cleaned powder is discharged along the guide cavity through the guide pipe 14 under the action of the external water pump. The guide pipe 14 can be connected to the next process equipment or collection container.

[0034] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
