Horizontal drum sieve sewage slag remover

Abstract

The embodiment of the invention relates to the technical field of sewage treatment, and concretely relates to a horizontal drum sieve sewage slag remover. The horizontal drum sieve sewage slag removercomprises a frame, a screen drum, a driving device and a V-shaped discharging plate; the screen drum is rotatably mounted on the frame around the shaft axis; at least one guide plate extending in theaxial direction of the screen drum is arranged on the inner wall of the screen drum; the driving device is fixedly mounted on the frame and is in transmission connection with the screen drum; the V-shaped discharging plate obliquely penetrates through the screen drum along the axial direction of the screen drum, and two ends of the V-shaped discharging plate extend out of the screen drum and arefixedly mounted on the frame; and the V-shaped discharging plate is provided with a V-shaped discharging groove, and the end part, close to a water inlet, of the V-shaped discharging plate is higher than the end part, close to a slag outlet, of the V-shaped discharging plate. The sewage slag remover filters out dirt in sewage through a cylindrical screen, so impurities in the sewage are preventedfrom blocking a sewage pump and a heat exchanger, a sewage source heat pump does not need to be disassembled and cleaned regularly, and manpower and material resources are saved.

Description

technical field [0001] The present application relates to the technical field of sewage treatment, in particular to a horizontal cylinder screen sewage slag remover. Background technique [0002] With energy saving, emission reduction, and green environmental protection becoming the mainstream concept of current economic development, urban raw sewage, as the cold and heat source of water source heat pump units, has been widely used in heating and air conditioning projects. However, the composition of urban sewage is extremely complex and unstable, containing a variety of suspended substances, flocs, grease, solid particles and domestic waste. With the increasing use of sewage source heat pumps, many disadvantages have also been revealed. Since the impurities in the raw sewage can easily block the sewage pump and heat exchanger, the sewage source heat pump needs to be disassembled and cleaned regularly, which consumes a lot of manpower and material resources, and the system c...

However, the composition of urban sewage is extremely complex and unstable, containing a variety of suspended substances, flocs, grease, solid particles and domestic waste. With the increasing use of sewage source heat pumps, many disadvantages have also been revealed

Since the impurities in the raw sewage can easily block the sewage pump and heat exchanger, the sewage source heat pump needs to be disassembled and cleaned regularly, which consumes a lot of manpower and material resources, and the system cannot heat or cool the building during cleaning, and sometimes even affects the power supply.
