Description

Technical Field

[0001] The utility model relates to a tank wall cleaning device. Background Art

[0002] At present, ordinary spray cleaning balls on the market are usually placed at the bottom of the tank. When in use, cleaning liquid is input into the cleaning ball and the cleaning ball rotates to achieve rotational cleaning of the pipe wall in the bottom of the tank. However, the existing cleaning balls generally have no telescopic function and are fixed in position. After cleaning, the cleaning balls are immersed in the medium for a long time, and the medium will also enter the cleaning pipe, resulting in a large dead corner area and not meeting the hygiene requirements. Utility Model Content

[0003] The utility model aims to provide a tank wall cleaning device, wherein the spray ball of the tank wall cleaning device can be opened or closed by controlling the extension of the cylinder, and the pipe wall cleaning operation is performed when the spray ball is opened, and the spray ball is retracted into the valve cavity when the spray ball is closed and does not contact the medium, thereby improving the sanitary conditions.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A tank wall cleaner comprises: a cylinder base, a piston is arranged in the cylinder base, the piston is connected to a valve body, a cleaning ball is connected to the top of the piston, a gas cavity is arranged between the cylinder base and the piston, when the gas cavity is inflated, the piston moves, the cleaning ball extends out of the tank bottom, and the valve body supplies liquid to clean the tank wall.

[0006] The utility model is further configured as follows: a valve core matched with the valve body is arranged on the top of the cleaning ball, a sealing ring is arranged between the valve core and the valve body, and when the cleaning ball moves to make the valve core abut against the valve body, the sealing ring blocks the medium in the tank from entering the valve body.

[0007] The utility model is further configured as follows: a bracket is arranged inside the piston, a spring is arranged between the bracket and the cylinder base, an exhaust port is arranged on the upper side of the cylinder base, and when the exhaust port is connected with the gas cavity, the spring drives the piston to reset.

[0008] The utility model is further configured as follows: the cylinder is connected with a connecting frame, and the connecting frame and the valve body are connected by a clamp to achieve the purpose of detachability.

[0009] In summary, the utility model has the following beneficial effects: the spray ball of the tank wall cleaner can be opened or closed by the cylinder control extension and retraction, and the pipe wall cleaning operation is performed when it is opened, and the spray ball is retracted into the valve cavity when it is closed and does not contact the medium, thereby improving the sanitary conditions.

[0013] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "page", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0014] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0015] In the description of the present utility model, "multiple" means two or more than two, unless otherwise clearly specified and specifically defined. In the present utility model, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0016] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0017] like Figure 1 , Figure 2 As shown, a tank wall cleaning device includes a cylinder base 1. A piston 2 is slidably arranged in the cylinder base 1, and the piston 2 can slide freely on the cylinder base 1. A bracket 3 is arranged at the bottom of the piston 2. A gas cavity 4 is formed between the bracket 3 and the cylinder base 1. An air inlet 5 connected to the gas cavity 4 is arranged on one side of the gas cavity 4.

[0018] A spring 6 is arranged between the upper side of the bracket 3 and the cylinder base 1. The spring 6 is used for resetting the piston 2. An exhaust port 7 is arranged on the upper side of the cylinder base 1.

[0019] As described above, when the air inlet 5 takes in air, the pressure in the gas cavity 4 increases, the bracket 3 moves upward, and thus drives the piston 2 to move upward. When the piston 2 moves, the spring 6 is compressed, and the piston 2 is gradually driven to continue to move upward to the position of the exhaust port 7, so that the gas cavity 4 is connected with the exhaust port 7, and the gas leaks, so that the piston 2 is reset under the action of the spring 6. The above arrangement achieves the purpose of making the piston 2 reciprocate.

[0020] A connecting frame 8 is provided on the cylinder base 1. A valve body 9 is connected to the top of the connecting frame 8 through a clamp. The piston 2 enters the valve body 9 and a cleaning ball 10 is provided in the valve body 9. A valve core 11 matching the valve body 9 is provided on the top of the cleaning ball 10. As described above, when the piston 2 moves upward, the valve core 11 moves upward together with the cleaning ball 10 to the bottom of the tank, and liquid is introduced into the liquid inlet of the valve body 9, so that the cleaning liquid is sprayed from the cleaning ball 10 to the bottom of the tank, thereby achieving the purpose of cleaning the tank bottom.

[0021] In addition, a sealing ring 12 is provided at the position of the valve core 11, so that when the valve core 11 abuts against the valve body 9, the medium in the tank will not enter the inside of the washer during the normal use of the tank.

[0022] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
