Description

Technical Field

[0001] The utility model belongs to the technical field of tank cleaning, and in particular relates to a sanitary tank structure with no dead angles during cleaning. Background Art

[0002] In equipment such as reactors, homogenizers, and mixing tanks, materials are introduced through the inlet and stirred or reacted chemically within the tank. After processing, thorough cleaning is often required in a CIP station (Cleaning in Place) to ensure equipment hygiene and prevent cross-contamination. The CIP system delivers cleaning fluid via pipes to cleaning balls, which evenly spray the fluid onto the tank's interior surface, effectively cleaning and disinfecting the equipment.

[0003] However, despite the significant advantages of CIP systems in terms of cleaning effectiveness, practical applications still present challenges, particularly when dealing with the unique characteristics of the injection nozzle. Because the injection nozzles of reactors and other equipment are typically vertically positioned, cleaning balls cannot effectively spray cleaning fluid directly onto the inner surface of the nozzle through the water outlet above it, as is the case with other flat or inclined surfaces. The cleaning fluid often struggles to reach deep areas within the nozzle, especially when the nozzle is deep, significantly reducing cleaning effectiveness and creating blind spots.

[0004] These blind spots often cannot be thoroughly cleaned using traditional CIP cleaning methods, leading to the accumulation of residues. This not only affects the subsequent use of the equipment but can also lead to contamination risks during the production process. Especially in industries such as food and pharmaceuticals, which require high hygiene standards, any incomplete cleaning can pose a safety hazard, affecting product quality and production efficiency. Utility Model Content

[0005] In order to solve the technical problem in the prior art that the filling port of the tank body is a vertical structure, and there are cleaning dead corners when using a CIP workstation to clean it, which affects subsequent use, the utility model provides a sanitary tank body structure with no cleaning dead corners.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A sanitary tank structure with no dead angles for cleaning comprises a tank body; a top cover is provided on the upper portion of the tank body; one or more injection ports are provided on the top cover, and the injection ports are trumpet-shaped and gradually expand from top to bottom; a first water pipe is provided through the middle of the top cover; a large ball is fixedly connected to the lower end of the first water pipe, and water outlet holes are evenly distributed on the large ball; the large ball is a hollow structure.

[0008] Furthermore, a second water pipe is provided inside the first water pipe; a small ball is fixedly connected to the lower end of the second water pipe; and the small ball is a hollow structure.

[0009] Furthermore, the small ball is located inside the big ball; a plurality of interconnected water outlet pipes are fixedly connected to the upper portion of the small ball, and the water outlet pipes extend to the outside of the big ball.

[0010] Furthermore, a first flange is fixedly connected to the top of the tank body; and a second flange is fixedly connected to the bottom of the top cover.

[0011] Furthermore, a circumferential array of U-shaped blocks is provided on the first flange and the second flange, and a threaded rod is threadedly connected to the upper portion of the U-shaped block; and a pad is fixedly connected to the lower end of the threaded rod.

[0012] Furthermore, a rubber ring is provided between the first flange and the second flange, and the rubber ring is used to increase the airtightness between the top cover and the tank body.

[0013] Furthermore, the upper portion of the second water pipe is in a folded structure, and the second water pipe passes through to the outside of the first water pipe.

[0014] Furthermore, a jacket is provided on the side surface of the tank body; and a discharge pipe communicating with the interior of the tank body is fixedly connected to the center of the lower surface of the tank body.

[0015] Beneficial effects of the utility model:

[0016] 1) The utility model adopts a trumpet-shaped injection port design that gradually expands from top to bottom. When the cleaning liquid is passed into the cleaning ball, the cleaning liquid inside the cleaning ball can be easily sprayed evenly into the injection port, thereby achieving the purpose of cleaning the dead corners inside the injection port, ensuring the cleanliness of the inside of the tank body, and will not affect the subsequent processing and use of materials.

[0017] 2) The utility model adopts the coordinated design of the large ball and the small ball, which can inject water into the large ball through the first water pipe, and then evenly clean the sides and bottom of the tank body with the cleaning liquid. The small ball is injected with water through the second water pipe. The angle design of the water outlet pipe on the small ball can spray the cleaning liquid onto the inner wall of the top cover and the inside of the injection port, realizing independent division of labor for cleaning and better cleaning effect. At the same time, since the top cover is difficult to clean, the large ball can stop cleaning when the small balls with independent division of labor are working, thereby achieving the purpose of saving resources.

[0018] 3) In the present invention, since the upper part of the second water pipe is a folded structure, when the cleaning liquid is passed into the first water pipe, the impact force on the second water pipe can be reduced, thereby extending the service life of the pipe; at the same time, by applying different water pressures to the first water pipe and the second water pipe, different cleaning efficiencies can be achieved, thereby ensuring that the interior of the tank can be cleaned quickly and the cleaning operation can be completed synchronously.

[0033] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in actual process is described in detail below:

[0034] Through the design of the trumpet-shaped injection port 6 that gradually expands from top to bottom, when the cleaning liquid is introduced into the cleaning ball, the cleaning liquid inside the cleaning ball can be easily sprayed evenly into the injection port 6, thereby achieving the purpose of cleaning the dead corners inside the injection port 6, ensuring the cleanliness of the inside of the tank body 1, and will not affect the subsequent processing and use of materials.

At the same time, since the top cover 5 is difficult to clean, the large ball 14 can stop cleaning when the small ball 16 with independent division of labor is working, thereby achieving the purpose of saving resources.

[0036] In addition, since the upper part of the second water pipe 13 is a folded structure, when the cleaning liquid is introduced into the first water pipe 12, the impact force on the second water pipe 13 can be reduced, thereby extending the service life of the pipe; at the same time, by applying different water pressures to the first water pipe 12 and the second water pipe 13, different cleaning efficiencies can be achieved, thereby ensuring that the interior of the tank body 1 can be cleaned quickly and the cleaning operation can be completed synchronously.
