[0002] In the pharmaceutical industry, the tank body plays a key role. Due to the particularity of the drug production process and the high standards of drug quality requirements, the cleaning work of the tank body is of extremely important significance. Generally, for the conventional tank body cleaning, the cleaning port is externally connected to a CIP station, and the purified water provided by the CIP drives two 360° rotating washing balls through pressure to form a vortex flow in the tank body with a fan-shaped jet flow, effectively removing the residual products and impurities on the surface of the container.

[0003] However, since the conventional tank body cleaning assembly uses an O-ring seal, gaps will be generated at the flange connection, making it difficult to clean. In addition, the existing stirring flange is relatively high, the inner wall straight pipe section is relatively long, the spray ball rod is designed as a straight rod, and there is a cleaning dead angle at each side of the inner side of the spray ball at both ends. Only slow cleaning can be achieved by water droplet sputtering at this place, with low efficiency and a large amount of wasted water.

[0004] Therefore, there is an urgent need to design a tank body which is convenient to clean to solve the problems that the existing flange angle and other dead angles are difficult to clean and water resources are wasted. Content of the Utility Model

Detailed Embodiments

[0036] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0037] As Figures 1-3 shown, the stirring flange of the existing conventional tank cleaning assembly has a relatively high height, the straight pipe section on the inner wall is relatively long, the spray ball rod is designed as a straight rod, and there is a cleaning dead angle at each side of the spray ball at both ends. Only slow cleaning can be achieved by water droplet sputtering at this place, with low efficiency and a large amount of wasted water. In addition, the use of an O-ring seal will cause gaps at the flange connection, making it difficult to clean. Therefore, the purpose of the present utility model is to provide a tank that is easy to clean, effectively solving the problems that the flange angle and other dead angles of the existing tank are difficult to clean and water resources are wasted.

[0038] Embodiment 1:

[0039] As Figure 4 、 Figure 5 、 Figure 10 shown, the present utility model provides a technical solution: a tank that is easy to clean, including:

[0040] a stirring assembly, a spraying assembly, a sealing assembly, and a tank body, etc.;

[0041] The stirring assembly includes a motor 101, a first magnetic part, and a second magnetic part. The first magnetic part is connected to the stirring shaft, and the stirring shaft passes through the sealing assembly and extends into the tank body. The motor 101 drives the first magnetic part to rotate through the second magnetic part, and then drives the stirring shaft to rotate.

[0042] The closing component is located at the top of the tank body, and it includes an upper sealing flange 102, a second lower sealing flange 204 and a sealing sheet body 207. The second lower sealing flange 204 has an obtuse angle part. Compared with the original right angle part design, the cleaning range is expanded, the cleaning dead angle 108 is eliminated, which is more conducive to the full coverage of spraying. In addition, on the premise of ensuring the material strength of the tank body, the thickness of the second lower sealing flange 204 is minimized as much as possible, thereby reducing the overall height of the closing component. On the one hand, the cleaning effect is improved, and the cleaning of the dead angle of the closing component is more thorough. On the other hand, the manufacturing cost of the product is also reduced. The second lower sealing flange 204 and the tank body are integrally designed. The upper sealing flange 102 is arranged on the second lower sealing flange 204, and the non-contact part between the upper sealing flange 102 and the second lower sealing flange 204 forms an obtuse angle, which improves the spraying effect. The sealing sheet body 207 is flat and arranged around the tank body to form a ring body. The upper and lower end faces of the sealing sheet body 207 are respectively connected to the upper sealing flange 102 and the second lower sealing flange 204. Using the sealing sheet body 207 for sealing, in the prior art, using an O-ring 107 for sealing is prone to gaps and is not easy to clean. In this embodiment, using the sealing sheet body 207 directly eliminates the gap between the upper and lower flanges, avoiding the situation that it is inconvenient to clean the residues in the gap.

[0043] The spraying component is located at the top of the tank body and below the closing component. The spraying components are arranged in pairs and symmetrically on both sides of the tank body to clean the tank body and the stirring component. The spraying component includes a first spraying ball rod 104, a spraying ball and a spraying flange. The spraying flange is connected to the tank body and seals the tank body and the first spraying ball rod 104. The first spraying ball rod 104 is a straight rod, and the distal end of the first spraying ball rod 104 is connected to the spraying ball. The spraying ball cleans the upper sealing flange 102, the second lower sealing flange 204 and the tank body. On the premise of meeting the cleaning effect, the shorter the length of the first spraying ball rod, the larger the angle of the obtuse angle part. Therefore, on the premise of meeting the cleaning effect, the length of the first spraying ball rod and the angle of the obtuse angle part can be adjusted according to needs.

[0044] Embodiment 2:

[0045] As Figure 6 、 Figure 7 、 Figure 10 shown, the present utility model provides a technical solution: a tank body that is easy to clean, including:

[0046] a stirring component, a spraying component, a closing component and a tank body, etc.;

[0047] The stirring component includes a motor 101, a first magnetic part and a second magnetic part. The first magnetic part is connected to the stirring shaft, and the stirring shaft passes through the closing component and extends into the tank body. The motor 101 drives the first magnetic part to rotate through the second magnetic part, and then drives the stirring shaft to rotate.

[0048] The closing component is located at the top of the tank body, and it includes an upper sealing flange 102, a second lower sealing flange 204, and a sealing sheet body 207. The second lower sealing flange 204 has an obtuse angle part. Compared with the original right angle part design, it expands the cleaning range, eliminates the cleaning dead angle 108, and is more conducive to the full coverage of spraying. In addition, on the premise of ensuring the material strength of the tank body, the thickness of the second lower sealing flange 204 is minimized as much as possible, thereby reducing the overall height of the closing component. On the one hand, this improves the cleaning effect and makes the cleaning of the dead angle of the closing component more thorough. On the other hand, it also reduces the manufacturing cost of the product. The second lower sealing flange 204 and the tank body are integrally designed. The upper sealing flange 102 is arranged on the second lower sealing flange 204, and the non-contact part between the upper sealing flange 102 and the second lower sealing flange 204 forms an obtuse angle. The sealing sheet body 207 is flat and arranged around the tank body to form a ring body. The upper and lower end faces of the sealing sheet body 207 are respectively connected to the upper sealing flange 102 and the second lower sealing flange 204. Using the sealing sheet body 207 to replace the O-ring 107 for sealing, in the prior art, using the O-ring 107 for sealing is prone to gaps and is not easy to clean. In this embodiment, using the sealing sheet body 207 directly eliminates the gap between the upper and lower flanges, avoiding the situation that it is inconvenient to clean the residues in the gap.

[0049] The spraying component is located at the top of the tank body and below the closing component. The spraying components are arranged in pairs and symmetrically on both sides of the tank body to clean the tank body and the stirring component. The spraying component includes a second spraying ball rod 204, a spraying ball, and a spraying flange. The spraying flange is connected to the tank body and seals the tank body and the second spraying ball rod 204. The second spraying ball rod 204 is provided with three sections, and each section of the ball rod is connected at an obtuse angle. The distal end of the second spraying ball rod 204 is close to the stirring shaft, and the distal end is connected to the spraying ball. The spraying ball cleans the upper sealing flange 102, the first and second lower sealing flanges 204, and the tank body. The three-section design of the second spraying rod enables the spraying ball to directly extend and connect to directly below the sealing flange, eliminating the cleaning dead angle 108 and improving the cleaning effect. The three-section connected spraying ball rod structure can also effectively avoid the problem that the spraying ball rod itself is not cleaned thoroughly. In addition, the three-section connected second spraying ball rod 204 is paired with the second lower sealing flange 204 having an obtuse angle part, so that the spraying ball connected to the second spraying ball rod 204 can achieve an ideal cleaning effect without being too close to the stirring shaft, avoiding the problem that the spraying ball is too close to the stirring shaft and is far from the positions on both sides of the tank body, resulting in the unclean cleaning of both sides of the tank body.

The first lower sealing flange 104 has a right-angle part. Under the material strength that can ensure the normal operation of the tank body, the thickness of the first lower sealing flange 104 is minimized as much as possible, thereby reducing the overall height of the sealing component. On the one hand, the cleaning effect is improved, and the cleaning of the dead corners of the sealing component is more thorough.
