Problems solved by technology
Although this design solves the problem of filter clogging, due to the filter recoil technology used, the normal sewage inflow must pass through the inflow check valve, filter, and the water pump and pipeline at the rear end of the filter.
Due to the low flow rate of the sewage flowing by gravity, it is easy to get stuck when the sewage flows into the check valve, which will easily cause the equipment to malfunction
In addition, since the direction of normal sewage inflow must pass through the water pump and pipeline at the rear end of the filter, a small amount of hair and paper towels will pass through the filter screen and accumulate in the inner cavity of the water pump. After a long time, it is easy to cause entanglement and blockage of the water pump.

The invention discloses a forced sewage discharge device, which comprises a header tank, a sewage delivery pump, a forced discharge delivery pump, a filter and a liquid level and time delay controller, wherein a sewage inlet pipe is arranged on the header tank, and the output end of the sewage inlet pipe is communicated with the filter. The forced sewage discharge device is characterized in that the inside of the header tank is provided with the filter and a sewage storage device; one end of the filter is connected with the sewage delivery pump through a conduit pipe, and the other end of the filter is connected with the sewage storage device through a solid sewage delivery pipe and a check valve; one end of the sewage storage device is connected with a water outlet pipe of the forced discharge delivery pump, and the other end of the sewage storage device is communicated with the outside of the header tank through a sewage outlet pipe; and the sewage delivery pump and the forced discharge delivery pump are communicated with the bottom of a tank body of the header tank through a water inlet pipe of the sewage delivery pump and a water inlet pipe of the forced discharge delivery pump respectively. The forced sewage discharge device improves the carrying capacity and the work efficiency of equipment.
Description
Technical field: [0001] The invention relates to a sewage lifting and discharging device. Especially the sewage discharge equipment with toilet in the basement. technical background: [0002] A large amount of sewage generated in modern production and life, when gravity gravity flow cannot be discharged or there are certain limitations and difficulties in gravity gravity flow, it is necessary to set up a sewage lifting and conveying device to lift or forcibly discharge it through its device. In the past, the lifting and conveying sewage was generally conveyed directly through the sewage pump. Since the sewage in production and life contains a large amount of hair, fibers and solid waste, the sewage pump is often entangled and blocked during the operation process, resulting in serious leakage, overload, over-temperature and other phenomena, thus affecting the earth. It affects the working efficiency and service life of the sewage pump. In order to solve these problems, man...
