Description

Technical Field

[0001] The utility model relates to a swimming pool water treatment device, in particular to a swimming pool water filtering and disinfection treatment device. Background Art

[0002] As swimming pools in artificial waters, swimming pools have been subject to increasing requirements for water environment as the number of swimmers continues to increase. In 2019, many national standard data of the "Sanitary Requirements for Water Quality Indicators of Artificial Swimming Pools" have been adjusted. Among them, the total colony count was adjusted from ≤1000 to ≤200, and the water turbidity was adjusted from ≤5 to ≤1, which also put forward higher requirements for the water treatment, filtration and sterilization equipment of swimming pools. The quality of water has a great impact on human health. During swimming, swimmers are immersed in water and their skin is in contact with water. Sometimes they can't help drinking a small amount of water or choking on water. A small amount of pool water will enter the respiratory tract, stomach, and ears. Various components in the water, such as bacteria, algae, disinfectants, and fungicides, will also enter the human body. Especially in summer, due to the large increase in the number of swimmers and the rise in temperature, bacteria and algae will be accelerated to reproduce, causing water quality to deteriorate. Every summer, there are reports of diseases such as conjunctivitis, fever, and respiratory infections caused by the deterioration of swimming pool water quality.

[0003] The filter sand tank currently used in swimming pools is in a sealed state, and there will be residual bacteria and algae in the tank. In order to completely disinfect the bacteria and algae in the swimming pool water, it is urgent to provide a more efficient swimming pool water filtering and sterilization device. Utility Model Content

[0004] The utility model aims to provide a device for filtering and sterilizing swimming pool water, which can make the sterilization and filtering treatment of swimming pool water more efficient and save the usage of swimming pool disinfectant.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A device for sterilizing and filtering swimming pool water, comprising a stainless steel tank body and a plurality of low-pressure mercury lamps; the stainless steel tank body is provided with a flange, a multi-way valve is connected in the middle of the flange, the multi-way valve is connected to a water inlet pipe, a water return pipe, and a water distribution pipe, and the lower end of the water distribution pipe is connected to a water inlet distributor; the stainless steel tank is filled with 2 / 3 inorganic antibacterial filter material;

[0007] The multiple low-pressure mercury lamps are distributed and arranged on the shoulder of the stainless tube tank body; the lower end of the low-pressure mercury lamp is sleeved in a high-transmittance quartz sleeve, and the quartz sleeve is fixed to the stainless steel tank body through a sealing rubber ring and inner and outer wire tubes; the power line at the upper end of the low-pressure mercury lamp passes through a PVC sleeve bonded to the tank body and is connected to the ballast, and the rectifier is connected to a 220V power supply.

[0008] A first stop valve is installed on the water inlet pipe, a second stop valve is installed on the water return pipe, and a third stop valve is installed on the swimming pool water circulation pipe; the swimming pool circulating water enters the upper part of the tank body (5) through the water inlet pipe and the multi-way valve in sequence, and then enters the water inlet distributor, the water distribution pipe, the multi-way valve, the water return pipe through the inorganic antibacterial filter material in the tank body, and finally enters the swimming pool.

[0009] The multiple low-pressure mercury lamps are distributed on the shoulder of the stainless tube tank body, and one low-pressure mercury lamp is distributed on the shoulder of the stainless tube tank body at intervals of 15-25 cm.

[0010] The distance between the low-pressure mercury lamp and the flange is 10 cm, thus forming a circle of ultraviolet layer to ensure that the water entering the return pipe can be effectively sterilized.

[0011] The inorganic antibacterial filter material has a particle size of 2-10 mm, and the inorganic antibacterial filter material has a bactericidal effect while filtering.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the utility model reasonably matches the traditional filter sand cylinder device with the low-pressure mercury lamp and the inorganic antibacterial filter material to form a filter sterilization device, which adds a sterilization function during the circulation and filtration of swimming pool water, and can ensure that there will be no bacteria residue and aquatic algae growth in the filter sand cylinder in a sealed state. The device can make the sterilization and filtration of swimming pool water more efficient, and also save the use of swimming pool disinfectants. BRIEF DESCRIPTION OF THE DRAWINGS
