Description

Technical Field

[0001] The utility model relates to a sewage discharge system, in particular to a self-cleaning cooling tower sewage discharge system. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It uses water and air flow to exchange heat and generate steam. The steam evaporates and takes away the heat to achieve evaporative heat dissipation, convection heat transfer, and radiation heat transfer. It is an evaporative heat dissipation device that dissipates the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature to ensure the normal operation of the system. The device is generally barrel-shaped, so it is called a cooling tower. At present, the side walls of cooling towers will accumulate scale after long-term cooling use, and some solid impurities will fall inside some cooling towers placed outdoors. If they are not cleaned for a long time, the cooling effect will be reduced and the cooling efficiency will be reduced. Generally, a cleaning device is set in the cooling tower to clean the scale and impurities.

[0003] For example, the prior art patent number CN 219284088 U discloses a self-cleaning cooling tower, including a cooling tower body, a driving assembly is arranged on the top of the cooling tower body, a cleaning assembly is arranged on the bottom of the driving assembly, and a clamping unit includes a clamping column, an extrusion groove is arranged on the bottom of the clamping column, and a clamping block is connected to the side wall of the extrusion groove. The patent realizes cleaning of the cooling tower body by arranging a driving assembly to drive the cleaning assembly, and the driving assembly and the cleaning assembly are connected by a connecting part. The insertion and clamping of the clamping unit in the connecting part and the insertion unit realizes the rapid installation and disassembly of the cleaning unit, thereby improving the efficiency of installation and maintenance.

[0004] Although the above patent achieves the purpose of self-cleaning of the cooling tower and easy disassembly and maintenance, the device is not equipped with a corresponding sewage discharge structure. After completing the cleaning of the inside of the cooling tower, the device only relies on the water flow to drive the scale and debris to be discharged from the drain pipe. In actual use, it is found that the scale and impurities scraped from the inner wall of the cooling tower sink to the bottom of the cooling tower and may re-attach to the bottom of the cooling tower and be difficult to discharge, or some larger debris is difficult to be discharged by the force of the water flow, resulting in poor cleaning effect of the device. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a self-cleaning cooling tower sewage discharge system, comprising a cooling tower body, the bottom surface of the cooling tower body is fixedly connected to the mounting plate, the upper surface of the mounting plate is overlapped with the bristles arranged on the bottom surfaces of two brush plates at the same time, the middle parts of the upper surfaces of the two brush plates are respectively fixedly connected to the bottom ends of two connecting shafts three, the upper ends of the two connecting shafts three are rotatably connected to a fixed plate one through a rolling bearing, the rear side surface of the fixed plate one is fixedly connected to the upper end of a scraper, and the bottom end of the scraper overlaps with the upper surface of the mounting plate.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] The utility model provides a brush plate and a scraper plate in contact with the mounting plate. After the mounting plate and the fixing plate 2 are fixedly mounted on the bottom of the cooling tower body with the self-cleaning function, when cleaning the cooling tower, the user can control the motor 2 to work by the wireless controller to drive the rotating shaft and the baffle plate to rotate ninety degrees by the worm and the worm gear to open the sewage pipe. Then the user controls the motor 1 to work by the wireless controller to drive the connecting shaft 1 and the fixing plate 1 to rotate so that the brush plate and the scraper plate fit the mounting plate and rotate around the connecting shaft 1. At this time, the gear 2 fits the gear 1 and rolls by the connecting shaft 2, the sprocket 2, the sprocket 3 and the sprocket 1 to drive the two connecting shafts 3 and the brush plate to rotate, so that the scale and impurities attached to the surface of the mounting plate are brushed off by the rotation of the brush plate, and the impurities are moved by the rotation of the scraper plate fit to the mounting plate to push the impurities into the sewage pipe for discharge, thereby avoiding that the impurities are re-attached and accumulated at the bottom of the cooling tower after the self-cleaning structure is used to clean the inside of the cooling tower and are difficult to discharge, thereby effectively improving the cleaning effect of the cooling tower.
