Novel vacuum flushing device

Abstract

The invention discloses a novel vacuum flushing device. The novel vacuum flushing device comprises a base fixed to the top of a water storage chamber and a vacuum pump arranged on the base and used for sucking air; one end of the vacuum pump is connected with a vacuumizing pipeline, and the other end of the vacuumizing pipeline is arranged in the water storage chamber; a pressure increasing and relieving mechanism is arranged at the upper end of the base and comprises a sealing assembly and a lifting assembly; the sealing assembly is driven to descend through descending motion of the lifting assembly, so that the sealing assembly seals an opening groove in the upper portion of the water storage chamber, the overall sealing performance of the water storage chamber is guaranteed when the water storage chamber is vacuumized, the pressure in the water storage chamber is increased, the water storage chamber is vacuumized, water in a water storage pool enters the water storage chamber, the sealing assembly is driven to ascend through ascending motion of the lifting assembly, the sealing assembly is separated from the opening groove in the upper portion of the water storage chamber, when the vacuum pump stops, the pressure relieving efficiency in the water storage chamber is greatly improved, and the potential energy of water is released instantly to achieve the flushing purpose; and an air filtering assembly can effectively prevent blockage in the vacuum pump.

Description

technical field [0001] The invention relates to the technical field of sludge deposition cleaning at the bottom of a reservoir, in particular to a novel vacuum flushing device. Background technique [0002] With the development of social economy and the continuous improvement of living standards, people have put forward higher requirements for the living environment. China has proposed corresponding solutions to adapt to environmental changes and deal with natural disasters caused by rain. Sponge city is a new conceptual measure of stormwater management. Aiming at the purpose of storing rainwater and flood water for infiltration, use, and discharge, a new technology and new method of water storage or collection pool are proposed. [0003] Because the rainwater contains a large amount of suspended solids and particulate matter, etc., these pollutants in the water will be deposited at the bottom of the pool after passing through the reservoir or the sump. Long-term depositio...

Problems solved by technology

[0005] The problem to be solved by the present invention is to drive the sealing assembly to descend through the descending movement of the lifting assembly, so that the sealing assembly seals the upper groove of the water storage chamber, which can effectively ensure that when the water storage chamber gradually forms a vacuum, the overall water storage chamber Sealing, increasing the pressure in the water storage chamber, making the water storage chamber form a vacuum, the water in the reservoir enters the water storage chamber, and the upward movement of the lifting component drives the sealing component to rise, so that the sealing component is separated from the upper groove of the water storage chamber , can greatly improve the pressure relief efficiency in the water storage chamber when the vacuum pump stops, so that the potential energy of the water body can be released instantaneously to achieve the purpose of flushing; The filter can re-filter the inhaled air to achieve the effect of double filtration and effectively prevent the clogging of the vacuum pump. A new type of vacuum flushing device
