Description

Technical Field

[0001] This utility model relates to the field of spray washing devices, and in particular to a rotary spray washing device. Background Technology

[0002] Liquid storage tanks are widely used in many industries such as chemical, food, and pharmaceutical to store various liquid raw materials, semi-finished products, or finished products. During actual use, the inside of the storage tank gradually accumulates dirt, impurities, microorganisms, and other contaminants due to the characteristics of the stored liquid. These contaminants not only affect the quality and purity of the stored liquid but may also lead to tank corrosion, reduce equipment lifespan, and even cause safety hazards.

[0003] Traditional cleaning methods for liquid storage tanks mainly include manual cleaning and fixed spray cleaning. Manual cleaning is labor-intensive and inefficient, and cleaning personnel need to enter the tank to work, facing the risks of working in a confined space. At the same time, it is difficult to ensure the thoroughness and uniformity of the cleaning. Although fixed spray cleaning improves cleaning efficiency to some extent, the fixed position of the spray nozzles creates cleaning dead spots, and it is not effective at cleaning stubborn stains on the tank walls. Utility Model Content

[0004] This application provides a rotary spray cleaning device, which solves the technical problems of existing solutions where manual cleaning of liquid storage tanks is labor-intensive and inefficient, and cleaning personnel need to enter the tank to work, facing the risk of working in a confined space. At the same time, fixed spray cleaning has cleaning dead corners and is not effective in cleaning stubborn stains on the tank wall.

[0005] The technical solution adopted in the embodiments of this application is as follows:

[0006] A rotary spray cleaning device includes a rotating shaft, a nozzle assembly, and a retaining ring. The rotating shaft passes through the top of a storage tank, with one end connected to an external cleaning fluid supply source, and has a cleaning fluid delivery channel inside. The nozzle assembly is fixedly connected to the upper end of the rotating shaft and located inside the storage tank. The nozzle assembly has multiple spray holes with different angles and directions, and the rotation is driven by the reaction force of the cleaning fluid spraying. The retaining ring is threadedly connected to the rotating shaft to fix the position of the nozzle assembly. A sealing device is provided at the connection between the rotating shaft and the top of the storage tank.

[0007] A further technical solution is that both the nozzle assembly and the rotating shaft are made of corrosion-resistant and wear-resistant materials.

[0008] A further technical solution is that the sealing device uses acid and alkali resistant rubber seals.

[0009] A further technical solution is that the nozzles on the nozzle assembly are distributed in a spiral or radial pattern.

[0010] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0011] 1. Utilizing a rotating shaft, nozzle assembly, retaining ring, and sealing device, the multi-angle spray holes combined with centrifugal rotation of the nozzle assembly can cover 100% of the inner wall of the storage tank, eliminating dead corners at the top and bottom that traditional fixed spraying methods cannot reach. Simultaneously, the cleaning time per cycle is shorter than manual cleaning, significantly improving cleaning fluid utilization and reducing downtime losses. Operators do not need to enter the tank, avoiding the risks of working in confined spaces. The self-lubricating nozzle assembly and corrosion-resistant material design extend service life and maintenance cycles. Adaptive pressure adjustment (such as a low-pressure mode for lightly soiled areas) reduces cleaning fluid consumption, meeting industrial wastewater reduction standards. Attached Figure Description

[0016] This application provides a rotary spray cleaning device, which solves the technical problems of existing solutions where manual cleaning of liquid storage tanks is labor-intensive and inefficient, and cleaning personnel need to enter the tank to work, facing the risk of working in a confined space. At the same time, fixed spray cleaning has cleaning dead corners and is not effective in cleaning stubborn stains on the tank wall.

[0017] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0019] A rotary spray washing device, such as Figure 1 , Figure 2 and Figure 3As shown, the system includes a rotating shaft 1, a nozzle assembly 2, and a retaining ring 3. The rotating shaft 1 extends through the top of the storage tank, with one end connected to an external cleaning fluid supply source. It has an internal cleaning fluid delivery channel. The nozzle assembly 2 is fixedly connected to the upper end of the rotating shaft 1 and located inside the storage tank. The nozzle assembly 2 has multiple spray holes at different angles and directions, and its rotation is driven by the reaction force of the cleaning fluid spray. The retaining ring 3 is threaded to the rotating shaft 1 to fix the position of the nozzle assembly 2. A sealing device is provided at the connection between the rotating shaft 1 and the top of the storage tank. The sealing device includes multiple O-rings, and the inner side of the O-rings is coated with a polytetrafluoroethylene lubricating layer. The connection between the rotating shaft 1 and the top of the storage tank can be either a compression fitting or a threaded connection, adapting to the installation requirements of different tank structures.

[0020] Both the nozzle assembly 2 and the rotating shaft 1 are made of corrosion-resistant and wear-resistant materials, and the nozzle assembly 2 has self-lubricating properties to reduce friction.

[0021] The sealing device uses acid and alkali resistant rubber seals.

[0022] The nozzles on nozzle assembly 2 are arranged in a spiral or radial pattern. The spray angle can cover both the vertical and horizontal surfaces of the inner wall of the storage tank.

[0023] Storage tank cleaning method: Secure the rotating shaft 1 to the top of the storage tank using a clamp or thread. Then connect the cleaning fluid supply source to the inlet of the rotating shaft. Start the cleaning fluid pumping system; the cleaning fluid is delivered to the nozzle assembly 2 through the internal channel of the rotating shaft 1. The nozzle assembly 2 rotates automatically under the pressure of the cleaning fluid, thoroughly cleaning the inner wall of the storage tank through multi-angle nozzles. Adjust the cleaning fluid pressure and flow rate to match different types of dirt. The cleaning fluid (alkaline solvent) is delivered to the nozzle assembly 2 via the rotating shaft 1; the nozzle assembly 2 rotates under the reaction force, completing the cleaning of the inner wall without leaving any dead corners.

[0024] Thanks to the use of a rotating shaft 1, nozzle assembly 2, retaining ring 3, and sealing device, the multi-angle spray holes of the nozzle assembly 2 combined with centrifugal rotation can cover 100% of the inner wall of the storage tank, eliminating dead corners at the top and bottom that traditional fixed spraying cannot reach. Simultaneously, the cleaning time per cycle is shorter than manual cleaning, significantly improving the utilization rate of cleaning fluid and reducing downtime losses. Operators do not need to enter the tank, avoiding the risks of working in confined spaces. The self-lubricating nozzle assembly 2 and corrosion-resistant material design extend its service life and maintenance cycle. Pressure adaptive adjustment (such as a low-pressure mode for lightly soiled areas) reduces cleaning fluid consumption, meeting industrial wastewater reduction standards.
