Description

Technical Field

[0001] The utility model belongs to the technical field of water treatment, and in particular relates to an automatic sewage discharge device for a pool. Background Art

[0002] Due to the workshop's production process, products must be cooled to room temperature before packaging. Using tap water as a coolant is the most economical and efficient method. Recycling cooling water further reduces costs while preventing environmental pollution caused by cooling water discharge. However, as cooling water passes through various pipes, equipment, and materials during recycling, it inevitably becomes contaminated with various debris, causing the cooling water to deteriorate. This not only affects product quality, but also causes pipe blockages, increasing production costs. Given this reality, the existing cooling water circulation process needs to be improved to enhance water quality. Utility Model Content

Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0022] like Figure 1 As shown, the utility model provides an automatic sewage discharge device for a water pool, including a tank body 1 and a controller 2. A filter cartridge 11 is provided inside the tank body 1, and a stainless steel filter cartridge is preferably used here; the filter cartridge 11 and the inner side surface of the tank body 1 form an annular cavity a that is closed at both ends. Preferably, an inlet pipe 3 connected to the filter cartridge 11 is provided at the upper part of the tank body 1, and the water inlet pipe 3 is connected to the water outlet of the pool 4. Preferably, a drain pipe 30 connected to the interior of the annular cavity a is provided at the lower part of the tank body 1, and a sewage pipe 5 connected to the filter cartridge 11 is provided at the bottom of the tank body 1. A control valve 6 is provided on the sewage pipe 5, and a pressure differential sensor 7 for real-time detection of the pressure difference between the annular cavity a and the filter cartridge 11 is provided on the tank body 1. The control valve 6 and the pressure differential sensor 7 are electrically connected to the controller 2 respectively. When the pressure differential measured by the pressure differential sensor 7 is greater than the water pressure set by the controller 2, the controller 2 controls the control valve 6 to open, discharge the water in the filter cartridge 11, and then discharge the intercepted dirt.

[0023] The utility model connects a device with automatic dirt cleaning function to the original circulating water pool. The circulating water in the workshop first passes through the device to filter out the dirt in the circulating water and then is cooled before entering the next process.

[0024] As a further preferred embodiment of the present invention, Figure 2 As shown, the filter cartridge 11 is a stainless steel filter cartridge comprising a filter screen 111 and a bracket 112. The filter screen 111 is fixed to the bracket 112. The present invention further incorporates a backwash mechanism within the filter screen 111 to scrape away trapped dirt adhering to the filter cartridge 11. Specifically, the backwash mechanism comprises a rotating bracket 8, a vertical shaft 9, and a reducer 10. The rotating bracket 8 is connected to the reducer 10 via the shaft 9. The reducer 10 is mounted on the top of the tank 1. A steel brush 20 is mounted on the rotating bracket 8, contacting the inner surface of the filter cartridge 11. The reducer 10 drives the shaft 9 to rotate, which in turn drives the rotating bracket 8. The steel brush 20 continuously scrapes the inner surface of the filter cartridge 11. After a few seconds of rotation, the adhering dirt is scraped off the surface of the filter cartridge 11 and discharged from the sewage pipe along with the water flow, quickly restoring the filter cartridge 11 to its original filtering function.

[0025] The device of the present invention has a pressure monitoring function. When a lot of dirt adheres to the filter cartridge 11, causing the filter cartridge 11 to be completely blocked and the pressure to be too high, the device will automatically open the control valve 6 and clean the filter cartridge 11 through strong cleaning to discharge all the dirt in the device from the sewage pipe 5.

[0026] The control valve 6 here is an electromagnetic control valve, and the steel brushes 20 are arranged along the height direction of the filter cartridge 11 and are symmetrically arranged on both sides of the rotating bracket 8. In the rotating state, the dirt attached to the filter cartridge 11 can be quickly removed.

[0027] In order to collect the discharged water containing dirt, the utility model further connects a dirt storage tank 40 to the outlet end of the sewage pipe 5 for storing the discharged dirt.

[0028] The utility model sets a rotating backwashing structure inside the filter cartridge 11, uses a stainless steel brush to quickly clean the dirt trapped inside the filter cartridge, and promptly restores the original filtering function. The setting of the self-cleaning function greatly improves the service life of the filter cartridge and the filtering efficiency of the filter cartridge.

[0029] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
