Sewage filter system provided with longitudinal ceramic membrane filter

Abstract

The invention discloses a sewage filter system provided with a longitudinal ceramic membrane filter. The sewage filter system comprises the filter, a sewage tank, a clear water tank, a water pump and connecting pipes, wherein the sewage tank is connected with the water pump through a pipe, the water pump is connected with one or more filters through a pipe, the filter is connected with the sewage tank through a pipe and provided with a clear water outlet which is connected with the clear water tank through a pipe; the filter is a ceramic membrane filter and comprises a ceramic membrane tube arranged in a closed casing, two ends of the closed casing serve as a sewage inlet and a sewage outlet respectively and are connected with the pipe. The ceramic membrane filter is longitudinally arranged, the sewage filter system can be widely applied to environmental sanitation vehicles for cleaning urban streets, the effective cleaning and sweeping operation time can be prolonged remarkably, times for the operation vehicles for performing clear water filling in a water station and sewage drainage in a garbage dump are reduced, the vehicle purchase and use cost in unit operation area can be reduced, the sewage drainage amount is reduced, and the water resource utilization rate is increased.

Description

technical field [0001] The invention belongs to the technical field of special sanitation vehicles, and in particular relates to a sewage filtration system with a longitudinal ceramic membrane filter, which is mainly used for the sewage filtration and recovery work of sanitation cleaning and sweeping vehicles. Background technique [0002] With the wide application of road cleaning vehicles in the sanitation industry, how to improve the effective operating time of cleaning vehicles and reduce the purchase and use costs of cleaning vehicles per unit operating area has become a new research topic. At present, the sewage collected by conventional vehicles on the market after washing the road surface is generally discharged directly, which not only causes waste of water resources, but also needs to repeatedly go to the water station to fill with clean water and discharge sewage to the garbage station, which greatly limits cleaning. Effective operating time of the vehicle. There...

Problems solved by technology

The conventional filtration system currently used in the market is not only huge in size, seriously occupying the limited space of the cleaning vehicle, but also has low sewage treatment efficiency, and the filter screen is easily blocked and difficult to clean. It has the characteristics of short working cycle and high maintenance cost.

[0003] The patent No. CN203899295U applied by Fujian Longma Environmental Sanitation Equipment Co., Ltd. is a "recycling device for reclaimed water for washing and sweeping vehicles". It uses PE sintered membrane as the filter membrane, which is easy to clog and needs to be cleaned manually after each use.

Zoomlion’s patent No. CN102561241A “Control method, device and system for washing and sweeping vehicles” adopts the method of pumping out the air and water in the filtration membrane for pressure filtration. The biggest disadvantage of this filtration method is The pressure difference inside and outside the membrane is small, the filtration efficiency is low, and the filter membrane is easy to clog, difficult to clean, and difficult to maintain

[0004] Although the ceramic membrane filter has been used in the field of liquid medicine purification, but its volume is very large, so it is the first time to apply it in the cleaning vehicle. How to maximize the inherent space of the cleaning vehicle is a problem that must be solved
