Description

Technical Field

[0001] The utility model relates to the technical field of vacuum drainage, in particular to a drainage device used in a vacuum drainage system. Background Art

[0002] The process of vacuum drainage is as follows: the vacuum station generates vacuum, transmits the sewage to the vacuum valve through the vacuum pipe, and then the discharge of sewage is controlled by the opening and closing of the vacuum valve. After the sewage passes through the vacuum valve, it flows into the vacuum tank of the vacuum station through the vacuum pipe, and then the vacuum tank discharges the sewage centrally.

[0003] Patent document CN218357905U discloses a vacuum drainage device in a municipal sewage well, which relates to the field of vacuum drainage technology, including a sewage tank, a vacuum main pipe fixedly connected to the top of the sewage tank, a vacuum water collecting pump connected to one end of the vacuum main pipe, a water inlet pipe arranged at one end of the vacuum water collecting pump, and a delivery pipe fixedly connected to the bottom of the sewage tank. The utility model is provided with a sewage tank, and the sewage tank is fixedly installed inside the sewage well by using the support frame and the mounting frame to provide support, so that when municipal sewage is used for drainage, the sewage is pumped in through the vacuum water collecting pump on the side of the sewage tank in cooperation with the water inlet pipe, and then input into the sewage tank through the vacuum main pipe for collection, and a filter rack and a filter are arranged inside the sewage tank to filter and process the large garbage and debris carried in the pumped sewage, and the detachable sealing disc can be disassembled and taken out directly for cleaning later, and the operation is simple and convenient.

[0004] However, the existing drainage equipment filters the garbage, but there is no observation device to observe the filtering part, and it is impossible to intuitively understand the garbage accumulation situation. In addition, the existing filter plates are mostly bottom filters, and there will be too much garbage blocking the filter components, causing the water flow to drop and affecting the sewage discharge. Therefore, it is necessary to improve such a structure to overcome the above defects. Utility Model Content

A vacuum pump is used to evacuate the tank body to maintain negative pressure inside the tank body.

[0033] In an embodiment, the conveying component includes an inlet pipe 110 and a drainage pipe 120. The inlet pipe is arranged on one side of the tank body, and a conveying space is provided in the inlet pipe. The sewage is conveyed into the tank body by the inlet pipe. The drainage pipe is arranged on the other side of the tank body, and a conveying space is provided in the drainage pipe. The sewage is discharged by the drainage pipe.

[0034] In an embodiment, the filter assembly includes a filter frame 210, which is disposed in a tank body. Both sides of the filter frame are provided with snap-fitting portions 211, which are snap-fitted into snap-fitting grooves of the tank body, and the filter frame filters sewage.

[0035] In the embodiment, the observation component includes an impurity observation window 310 and a water volume observation window 320, and the impurity observation window is arranged in the tank body. Glass is arranged in the impurity observation window, and the glass is made of borosilicate glass. Borosilicate glass has excellent chemical stability. At the same time, borosilicate glass can well withstand the pressure from vacuuming without breaking. The filter frame is observed through the impurity observation window to understand the accumulation of impurities in the tank body, so as to clean the impurities in time and increase the filtration efficiency of sewage. The water volume observation window is arranged in the tank body, and the water volume observation window is located directly below the impurity observation window. Glass is arranged in the water volume observation window, and the glass is made of borosilicate glass. Borosilicate glass has excellent chemical stability.
