Description

Technical Field

[0001] This utility model relates to the field of storage tank technology, and in particular to a stainless steel storage tank. Background Technology

[0002] In industrial production, stainless steel storage tanks are widely used for material storage and mixing. To ensure production hygiene and product quality, storage tanks need to be cleaned regularly to remove residual material from their inner walls. Currently, tank cleaning devices typically use fixed spray balls or static spray pipes. However, this fixed spraying method has limited coverage and is prone to creating cleaning blind spots; furthermore, the spraying device is independent of the mixing device, resulting in a complex structure and high installation and maintenance costs; and some spray nozzles on the spraying device are also easily clogged by material, affecting the cleaning effect and equipment lifespan. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a stainless steel storage tank that combines spraying with a stirring shaft, utilizing rotating spraying to significantly improve cleaning efficiency.

[0004] Therefore, the technical solution of this utility model is as follows: a stainless steel storage tank, including a tank body and a supporting mechanism, wherein the tank body is provided with a feed inlet at the top and a discharge outlet at the bottom, and the tank body is fixed to the supporting structure at the bottom; a stirring shaft is provided inside the tank body, and a plurality of stirring blades are provided on the stirring shaft, the upper half of the stirring shaft being a hollow structure that penetrates through the inside and outside of the tank body; it also includes a spraying mechanism, which includes a spraying disc and a spraying pipe, the spraying disc being mounted on the stirring shaft and communicating with the inside of the stirring shaft; the spraying pipe is connected to the top of the stirring shaft through a rotary joint, and the spraying pipe and the spraying disc are connected through the hollow structure inside the stirring shaft; the spraying disc is provided with a plurality of spray holes at different angles.

[0005] Based on the above scheme and as a preferred embodiment of the above scheme: the spray plate is composed of multiple independent fan-shaped spray units. The end of the spray unit is provided with a hollow rod with external threads, which can be installed in the mounting hole of the stirring shaft and connected to the spray channel inside the stirring shaft.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the spray holes on the spray plate are divided into 3 groups. The first group of spray holes is located on the upper end face of the spray plate and is set at an elevation angle of 40 to 50 degrees. The second group of spray holes is located on the lower end face of the spray plate with the orifice vertically downward. The third group of spray holes is located on the lower end face and outer edge of the spray plate with the orifice set at a depression angle of 30 to 40 degrees.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the top of the stirring shaft extends out of the top of the tank, and the two are rotatably coupled through a sealed bearing; the top of the tank is equipped with a stirring motor, which drives the stirring shaft to rotate.

[0008] Based on the above scheme and as a preferred option: the spray plate is higher than the highest liquid level line of the tank, with a distance difference greater than 20cm.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the tank body is a columnar cylindrical structure with an inclined conical bottom structure, and the cylindrical structure and the conical bottom structure are connected by an arc transition.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: a multi-channel rotary joint can be connected above the stirring shaft, one channel connecting to the spray pipe and the other channel connecting to the inert gas.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By combining the spray mechanism with the agitator shaft, the agitator shaft can be used to drive the spray plate to rotate during cleaning, allowing the water flow from the spray nozzles to dynamically cover more areas inside the tank. This changes the problem of limited coverage of traditional fixed sprayers, significantly reduces cleaning dead spots, and improves the thoroughness of cleaning.

[0013] The spray plate is equipped with spray holes at different angles. The spray holes at an upward angle of 40 to 50 degrees can rinse the top and upper inner wall of the tank, the vertically downward spray holes can specifically clean the middle of the tank and the area near the agitator blades, and the spray holes at a downward angle of 30 to 40 degrees can cover the lower part of the tank and the bottom of the cone. The combination of multiple angles can achieve all-round, no dead angle cleaning of the inside of the tank.

[0014] 3. The spray plate consists of multiple independent spray units, which are fixed to the agitator shaft by threads. When a spray unit is damaged or the spray holes are blocked, the unit can be disassembled and replaced individually without replacing the entire spray plate, thus reducing maintenance costs. At the same time, this detachable structure also facilitates individual cleaning of the spray holes, reducing maintenance difficulty.

[0015] 4. A multi-channel rotary joint can be connected above the stirring shaft. In addition to connecting to the spray pipe for cleaning, another channel can be connected to inert gas. When it is necessary to protect the material inside the tank from oxidation, inert gas can be introduced through this channel without the need for a separate inert gas inlet structure, thus improving the functionality and flexibility of the storage tank.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" or "a number" means two or more, unless otherwise explicitly specified.

[0023] See the attached drawings. The stainless steel storage tank described in this embodiment includes a tank body 1, a stirring mechanism, a spraying mechanism, and a support mechanism 2. The tank body 1 is made of 304 or 316L stainless steel and has an overall vertical cylindrical structure. The bottom of the tank body 1 has an inclined conical bottom structure 11, and the cylindrical structure and the conical bottom structure are connected by an arc transition, thereby reducing dead corners at the bottom. The feed inlet 12 is located at the top of the tank body 1, and the discharge outlet 13 is located at the bottom of the tank body 1. The support mechanism 2 adopts the form of legs or a skirt. In addition, the tank body 1 is also equipped with conventional designs such as a discharge port and a level gauge; these are mature technologies and will not be described in detail here.

[0024] The stirring mechanism includes a stirring shaft 31, stirring blades 32, and a stirring motor 33. The stirring shaft 31 passes through the top of the tank body 1, and the two are rotatably coupled through a sealed bearing. The stirring motor 33 is installed on the outer side of the top of the tank body 1. A worm gear is provided on the output shaft of the stirring motor 33, and a worm wheel structure that meshes with the worm gear is fitted on the outer side of the stirring shaft 31, so that the stirring motor 33 can drive the stirring shaft 31 to rotate. The stirring shaft 31 extends vertically into the tank body 1, and the stirring blades 32 are fixed to the lower part of the stirring shaft 31. The structure can be selected as paddle type, anchor type, or turbine type according to the characteristics of the material.

[0025] The upper part of the stirring shaft 31 is hollow and can serve as a spray channel 34 connecting the inside and outside of the tank 1. The spray mechanism includes a spray plate 41 and a spray pipe 42. The spray plate 41 is composed of multiple independent fan-shaped spray units. The end of each spray unit is provided with a hollow rod 43, which has external threads. It can be threaded into the mounting hole of the stirring shaft 31 and connected to the spray channel 34 inside the stirring shaft 31. The spray plate 41 is higher than the highest liquid level line of the tank, with a distance difference of more than 20cm. When the storage tank is storing and stirring materials normally, the materials will not come into contact with the spray holes, which can effectively avoid the situation where materials adhere to the spray holes and cause blockage, ensuring that the spray mechanism can work normally during cleaning.

[0026] A rotary joint 5 connects to the spray pipe 42 above the stirring shaft 31. The spray pipe 42 and spray plate 41 are connected via an internal spray channel 34. The rotary joint 5 does not interfere with the normal rotation and stirring operation of the stirring shaft 31. Depending on the application, a multi-channel rotary joint can be rotatably installed. Besides connecting to the spray pipe for cleaning, another channel can be connected to inert gas. When oxidation prevention or other protection is required for the materials inside the tank, inert gas can be introduced through this channel, eliminating the need for a separate inert gas inlet structure and enhancing the tank's functional versatility and operational flexibility.

[0027] The spray plate 41 is provided with at least three sets of spray holes. The first set of spray holes 44 is located on the upper end face of the spray plate and is set at an upward angle of 40 to 50 degrees. It is mainly used to clean the top of the tank and the upper part of the tank. The second set of spray holes 45 is located on the lower end face of the spray plate and the orifice is vertically downward. It is mainly used to clean the stirring blades and the middle part of the tank. The third set of spray holes 46 is located on the lower end face and outer edge of the spray plate and the orifice is set at a downward angle of 30 to 40 degrees. It is mainly used to clean the lower part and bottom of the tank. The multi-angle combination achieves all-round and dead-angle cleaning of the inside of the tank, improving the thoroughness of cleaning.
