Description

Technical Field

[0001] This utility model relates to the field of spraying devices, specifically a high-stability ultrapure PTFE spraying device. Background Technology

[0002] Industries such as chemical, semiconductor, pharmaceutical, and power industries need to use storage tanks to store various corrosive chemicals. After the chemical raw materials in the storage tanks are used up, the tanks need to be cleaned regularly. Currently, the cleaning of chemical storage tanks is generally done manually. Because the tanks have stored chemicals, the chemicals adhering to their inner walls and bottoms are difficult to clean, resulting in a problem where a lot of manpower and resources are needed for cleaning but it is still not completely clean. At the same time, the chemicals may also cause serious consequences such as respiratory or skin damage to workers during the cleaning process.

[0003] For example, utility model publication CN218361160U discloses a high-stability ultrapure PTFE spraying device, characterized by: a spray pipe, one end of which has a water inlet connection, and the other end has a spray head; a positioning flange is provided on the spray pipe. Preferably, the entire spraying device is made of high-stability ultrapure PTFE material, which has excellent corrosion resistance and high pressure resistance. The water inlet connection is used to connect to an external water supply pipe, and the positioning flange is used to fix the spraying device to the storage tank. After the spray pipe is connected to the external water supply pipe, water is sprayed into the storage tank through the spray head to clean the tank. The spray head can rotate with the water pressure to clean the inner lining of the storage tank from all directions without manual intervention. Two positioning flanges are provided and are tightly fitted with the spray pipe.

[0004] The device of the above-mentioned utility model is made of highly stable ultrapure polytetrafluoroethylene material, which has excellent corrosion resistance and high pressure resistance. However, the device only has a single spray head at the bottom of the spray pipe. When cleaning the inner wall of tanks of different diameters, the spray radiation range of a single spray head is limited, resulting in limited cleaning effect. At the same time, the device cannot be used as a whole after a single spray head becomes blocked. Utility Model Content

[0005] The purpose of this invention is to provide a highly stable ultrapure PTFE spraying device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-stability ultrapure PTFE spraying device, comprising a spray pipe, wherein two adjacent spray pipes are fixedly installed by flanges, and a spraying assembly is fixedly connected to the bottom end of the spray pipe.

[0007] Preferably, the spray assembly includes a water distribution cylinder fixedly installed at the bottom end of the spray pipe.

[0008] Preferably, the water distribution cylinder has a chamber and is a disc-shaped structure.

[0009] Preferably, a number of spray heads communicating with its chamber are fixedly installed at the bottom end of the water distribution cylinder.

[0010] Preferably, several of the spray heads are arranged in a ring shape along the bottom of the water distribution cylinder.

[0011] Compared with the prior art, the advantages of this utility model are as follows:

[0012] This invention connects the top of the spray pipe to an external water supply pipe, and then fixes multiple spray pipes together with flanges. The bottom of the spray pipe is fixedly connected to a disc-shaped water distribution tube with a cavity. Several spray heads are arranged in a ring at the bottom of the water distribution tube, so that the inner wall of the tank can be cleaned more thoroughly through multiple ring-distributed spray heads. At the same time, the continued use of the device is not affected by the blockage of a single spray head. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1

[0018] Please see Figures 1-2 The figure shows a high-stability ultrapure PTFE spraying device, which includes a spray pipe 1. Two adjacent spray pipes 1 are fixedly installed by flanges 2, and a spraying assembly 3 is fixedly connected to the bottom end of the spray pipe 1.

[0019] In this embodiment, the spray assembly 3 includes a water distribution cylinder 31 fixedly installed at the bottom end of the spray pipe 1. The water distribution cylinder 31 has a chamber and is a disc-shaped structure. Several spray heads 32 communicating with the chamber are fixedly installed at the bottom end of the water distribution cylinder 31. The several spray heads 32 are distributed in a ring along the bottom end of the water distribution cylinder 31.

[0020] Furthermore, after connecting the top of the spray pipe 1 to the external water supply pipe, multiple spray pipes 1 are fixedly installed together by flange 2. The bottom end of the spray pipe 1 at the bottom is fixedly connected to a disc-shaped water distribution cylinder 31 with a cavity. Several spray heads 32 are arranged in a ring at the bottom end of the water distribution cylinder 31, so that the inner wall of the tank can be cleaned more thoroughly through multiple ring-distributed spray heads 32. At the same time, if a single spray head 32 is blocked, it will not affect the continued use of the device.

[0021] The working principle of this utility model is as follows: After the top end of the spray pipe 1 is connected to the external water supply pipe, multiple spray pipes 1 are fixedly installed together by flange 2. The bottom end of the spray pipe 1 at the bottom is fixedly connected to a disc-shaped water distribution cylinder 31 with a cavity. Several spray heads 32 are arranged in a ring at the bottom end of the water distribution cylinder 31, so that the inner wall of the tank can be cleaned more thoroughly through multiple ring-distributed spray heads 32. At the same time, if a single spray head 32 is blocked, it will not affect the continued use of the device.
