Description

Technical Field

[0001] This utility model relates to the field of water pretreatment technology, and in particular to a water pretreatment device for a water supply system. Background Technology

[0002] Pretreatment devices can effectively remove impurities such as suspended solids, organic matter, colloids, and microorganisms from raw water, reduce the turbidity, color, and organic matter content of raw water, prevent these impurities from clogging, polluting, and damaging subsequent treatment equipment, and improve the operating efficiency and stability of the entire water supply system.

[0003] In urban water supply systems, traditional water pretreatment devices are prone to clogging of their internal filter components by impurities, requiring regular cleaning and replacement. However, the installation and disassembly of these filter components are complex, making cleaning or replacement inconvenient. Therefore, we propose a new water pretreatment device for water supply systems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a water pretreatment device for a water supply system.

[0005] This utility model is achieved using the following technical solution: a water pretreatment device for a water supply system, comprising a water tank, an inlet pipe connected to the left end of the water tank, an outlet pipe connected to the right end of the water tank, a tank cover provided on the top of the water tank, a threaded rod threadedly connected to the inner wall of the tank cover, a filter assembly provided inside the water tank, a fixing ring fixedly connected to the inner wall of the water tank, a pressure plate fixedly connected to the bottom of the tank cover, a plurality of through holes opened on the surface of the pressure plate, a support column fixedly connected to the bottom of the water tank, and a slag discharge pipe connected to the bottom of the water tank;

[0006] The filtration assembly includes a fine filter screen, a first connecting rod fixedly connected to the top of the fine filter screen, a quartz sand filter screen fixedly connected to the top of the first connecting rod, a second connecting rod fixedly connected to the top of the quartz sand filter screen, an activated carbon filter screen fixedly connected to the top of the second connecting rod, and a pull ring fixedly connected to the top of the activated carbon filter screen.

[0007] The above technical solutions effectively remove various impurities and harmful substances from water by using fine filter screens to filter out fine suspended solids and impurities, using quartz sand filter screens to filter out suspended solids and tiny particles, and using activated carbon filter screens to adsorb organic matter, odors, and pigments. This improves the purity of the water.

[0008] As a further improvement to the above solution, the bottom of the fine filter screen contacts the top of the fixing ring, and the surfaces of the quartz sand filter screen and the activated carbon filter screen are both in contact with the inner wall of the water tank.

[0009] The above technical solution uses a fixing ring to support and place the fine filter screen, facilitating subsequent installation.

[0010] As a further improvement to the above solution, the top of the activated carbon filter is in contact with the bottom of the pressure plate.

[0011] The above technical solution uses a pressure plate to squeeze the activated carbon filter screen, thereby installing and fixing the filter assembly as a whole, which facilitates subsequent disassembly and maintenance.

[0012] As a further improvement to the above solution, the water outlet pipe is located at the upper end of the activated carbon filter, and the lower end of the threaded rod passes through the tank cover and is threadedly connected to the inner wall of the water tank.

[0013] With the above technical solution, since the water outlet pipe is located at the top of the activated carbon filter, the discharged water is filtered for subsequent use.

[0014] As a further improvement to the above solution, three support columns are provided, and the three support columns are arranged in a circle around the water tank.

[0015] The above technical solution improves the stability of the water tank by using three support columns to support it.

[0016] As a further improvement to the above solution, a valve is installed on the inner wall of the slag discharge pipe.

[0017] The above technical solution allows for easy opening and closing of the slag discharge pipe via a valve.

[0018] As a further improvement to the above solution, the top of the box cover is connected to a flushing pipe, and a sealing cap is threaded onto the surface of the flushing pipe.

[0019] The above technical solution allows external flushing pipes to easily enter the interior of the water tank to flush the filter components inside. The threaded sealing cap facilitates quick disassembly and installation, and the sealing cap also seals the flushing pipe to prevent water leakage.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This utility model, by setting up a tank cover, threaded rod, filter assembly, fixing ring, and pressure plate, specifically uses the filter assembly to effectively remove various impurities and harmful substances from the water, improving the purity of the water. By disassembling the threaded rod, the tank cover can be removed, and the activated carbon filter, quartz sand filter, and fine filter can be taken out by pulling the ring, facilitating subsequent replacement. When installing the filter assembly, the filter assembly is placed inside the water tank, and the fine filter is limited by the fixing ring. The tank cover is installed on the top of the water tank by the threaded rod, and the pressure plate at the bottom of the tank cover presses and fixes the activated carbon filter, facilitating quick installation and disassembly and improving the convenience of subsequent maintenance.

[0022] This utility model, by setting up a flushing pipe, a sealing cover, and a slag discharge pipe, allows the filter components to be disassembled by rotating the sealing cover when cleaning is required. An external water pipe is then inserted into the water tank through the flushing pipe to flush the activated carbon filter, quartz sand filter, and fine filter. This extends the service life of the filter components and improves their practicality. The slag discharge pipe facilitates the removal of impurities from the flushing process.

[0032] The filter assembly 6 includes a fine filter screen 601, a first connecting rod 602 fixedly connected to the top of the fine filter screen 601, a quartz sand filter screen 603 fixedly connected to the top of the first connecting rod 602, a second connecting rod 604 fixedly connected to the top of the quartz sand filter screen 603, an activated carbon filter screen 605 fixedly connected to the top of the second connecting rod 604, and a pull ring 606 fixedly connected to the top of the activated carbon filter screen 605. The inlet pipe 2 is connected to the water supply pipe, and the outlet pipe 3 is connected to an external pipe. In use, water is supplied to the water tank 1 through the water supply pipe via the inlet pipe 2. The fine filter screen 601 filters out fine suspended solids and impurities in the water, the quartz sand filter screen 603 filters out suspended solids and tiny particles in the water, and the activated carbon filter screen 605 adsorbs organic matter, odors, and pigments in the water. This effectively removes various impurities and harmful substances from the water, improving the purity of the water.

[0033] The bottom of the fine filter screen 601 contacts the top of the fixing ring 7, and the surfaces of the quartz sand filter screen 603 and the activated carbon filter screen 605 are in contact with the inner wall of the water tank 1.

[0034] The top of the activated carbon filter 605 contacts the bottom of the pressure plate 8, and the activated carbon filter 605 is squeezed and fixed by the pressure plate 8.

[0035] The water outlet pipe 3 is located at the upper end of the activated carbon filter 605. The lower end of the threaded rod 5 passes through the cover 4 and is threadedly connected to the inner wall of the water tank 1. By disassembling the threaded rod 5, the cover 4 can be removed. Pulling the pull ring 606 allows the activated carbon filter 605, the quartz sand filter 603, and the fine filter 601 to be taken out for easy replacement later.

[0036] Three support columns 10 are set, and the three support columns 10 are arranged in a circle around the water tank 1.
