Description

Technical Field

[0001] The utility model relates to the technical field of water supply and drainage equipment, in particular to a self-cleaning water supply and drainage device. Background Art

[0002] Domestic water includes public service water and household water. Public service water refers to water used for urban social public life services. It includes water used by administrative institutions, military camps and public facilities services, social services, wholesale and retail trade, hotels and restaurants, and other public service industries. Household water refers to the daily life water used by all households within the city. It includes water used by urban residents, farmers' households, and public water supply stations.

[0003] After urban residents use water at home, some families often install water purifiers at the end of the household water supply in order to improve the quality of water. Currently, most water purifiers on the market use filter elements to provide water filtration effects. After a long period of use, the filter element inevitably needs to be replaced, which has certain disadvantages. Therefore, we propose to design a self-cleaning water supply and drainage device.

[0023] See also Figure 1-4 The utility model provides a self-cleaning water supply and drainage device, including a self-cleaning cylinder 1, a drainage pipe 2 is fixedly connected to the bottom of the self-cleaning cylinder 1, and a filter cylinder 3 is fixedly connected to the top of the drainage pipe 2, wherein the filter cylinder 3 includes a cylinder body, a filter screen is embedded and fixedly connected in the middle of the cylinder body, and a microporous filter screen is arranged on the outside of the filter screen. The mesh size of the microporous filter screen is 150 meshes, which is convenient for filtering the water quality at the end of the water supply, making the water supply purer and improving the water quality of users.

[0024] A sewage pipe 4 is fixedly connected to the bottom of the self-cleaning cylinder 1, and a water supply pipe 5 is fixedly connected to one side of the outer wall of the self-cleaning cylinder 1 near the top. Valves are provided on the outside of the sewage pipe 4 and the water supply pipe 5 to facilitate the control of the start and stop of water supply and drainage.

[0025] A self-cleaning motor 6 is fixedly connected to the center of the top of the self-cleaning cylinder 1. The driving shaft of the self-cleaning motor 6 passes through the top of the self-cleaning cylinder 1 and is fixedly connected to a spiral brush 7, wherein the spiral brush 7 is arranged in a spiral shape, and the inner wall of the spiral brush 7 is fixedly connected with bristles 8, and the bristles 8 are in contact with the outer wall of the filter cylinder 3. When the spiral brush 7 is not rotating, it is wrapped around the outside of the filter cylinder 3, providing a larger penetrable area, which is convenient for external water supply to pass through the filter cylinder 3 and enter the drain pipe 2; when the spiral brush 7 rotates, most of the outer surface of the filter cylinder 3 can be covered and cleaned, and the internal clean water can flow outward to facilitate the flushing and removal of impurities on the filter screen.

[0026] The bottom of the drain pipe 2 is provided with a water inlet pipe 9, and a three-way valve 10 is provided between the drain pipe 2 and the water inlet pipe 9. The three-way valve 10 includes a valve body 101, and an adjusting motor 102 is fixedly connected to the outside of the valve body 101. The driving shaft of the adjusting motor 102 passes through the valve body 101 and is fixedly connected to a valve core 103. A self-cleaning water inlet pipe 104 is fixedly connected to one side of the outer wall of the valve body 101. A three-way valve is provided inside the valve core 103, and the three-way valve is connected to the drain pipe 2, the water inlet pipe 9 and the self-cleaning water inlet pipe 104 respectively. By adjusting the three-way direction of the valve core 103, it is convenient to control the inflow and outflow of water, and it is convenient to perform self-cleaning in the self-cleaning cylinder 1.

[0027] In this embodiment, the self-cleaning motor 6 and the adjusting motor 102 are both servo motors, and their driving shafts can be self-locking. The self-cleaning motor 6 and the adjusting motor 102 are both connected to an external power supply, and can work together through external PLC programming control, and are combined with a timing circuit to facilitate regular start and stop of self-cleaning work in the barrel.

[0028] When in use, water is injected into the self-cleaning cylinder 1 through the water supply pipe 5, the water passes through the filter cylinder 3 and enters the drain pipe 2, and then passes through the three-way valve 10 and enters the house from the water inlet pipe 9, which is convenient for users to use.

[0029] The valves in this device are all electromagnetic valves, and the coordinated work between the valves, the self-cleaning motor 6 and the regulating motor 102 can be realized by external PLC programming, which is a prior art and will not be described here one by one. During use, a timing circuit is required to realize the regular start of the motor.

[0030] During self-cleaning, the water supply pipe 5 and the water inlet pipe 9 are closed, and the water supply is temporarily shut off. The time can be set at a time period with less water consumption, such as midnight, and can be arranged by the user. After the water supply is shut off, the self-cleaning water inlet pipe 104 is opened, wherein the self-cleaning water inlet pipe 104 is connected to an external water source (the water source can be a tap water pipe), and the regulating motor 102 is started, driving the valve core 103 to rotate, so that the three-way only connects the self-cleaning water inlet pipe 104 to the drain pipe 2.

[0031] At this time, water flows back into the filter cartridge 3, and the self-cleaning motor 6 is started at the same time, driving the spiral brush 7 to rotate, cooperating with the water seeping out from the filter cartridge 3 to clean the outside of the filter cartridge 3. Since the water supply pipe 5 is closed, the water with impurities is discharged from the self-cleaning cartridge 1 through the opened sewage pipe 4 (the sewage pipe 4 can be connected to the sewer), thereby realizing the self-cleaning of the self-cleaning cartridge 1, which not only facilitates the purification of the subsequent water supply and improves the water quality of users, but also avoids the accumulation of impurities that affects the subsequent purification efficiency.

[0032] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
