Description

A single-pump basement sewage lifting equipment

technical field

The utility model relates to automatic sewage lifting equipment, in particular to a single-pump basement sewage lifting equipment.

Background technique

At present, the usual way to discharge underground toilet sewage is to set up a sump on the basement floor, collect the sewage from sanitary ware, and use a submersible pump to lift it to an outdoor underground sewage pump well, or drain the sewage from the toilet by itself. Enter the outdoor underground sewage pump well, and then use the submersible sewage pump to lift and discharge the sewage into the sewage inspection well near the pump well; these common practices have the following disadvantages: 1. There are solid substances such as feces in the sewage, which will easily cause blockage if it is not cleaned for a long time. 2. Since the sump is shallow, the operation of the submersible sewage pump that starts and stops according to the water level is not reliable; 3. The airtightness of the sump is not good, there is an odor, and the sanitary condition is poor; 4. The pump is built outdoors Well, the depth is deeper, the investment is larger, and the management is inconvenient. 5. The solid-liquid separator is designed inside the water storage tank, which is inconvenient for installation and maintenance; 6. Without automatic backwashing function, the water storage tank needs to be cleaned regularly after long-term operation. .

Utility model content

To solve the above technical problems, the utility model provides a single-pump basement sewage lifting equipment which has no odor emission, is environmentally friendly and hygienic, saves construction investment costs and is easy to install.

In order to overcome the defects of the above-mentioned prior art, the utility model is a single-pump basement sewage lifting equipment, which includes a water inlet flange, a water outlet flange, a water inlet check valve, a water outlet check valve, an inlet water distributor, a solid-liquid Separator, submersible sewage pump, water storage tank, one end of the water inlet flange is connected to the water inlet, and the other end is connected to the water inlet pipe. A water inlet check valve is provided in the middle of the water inlet pipe, and the water inlet check valve The one-way control valve can only allow sewage to flow in, and does not allow sewage to flow out from the other direction. The water inlet pipe is connected to the water inlet flange and the lower part is provided with a water inlet water distributor. Guaranteed to enter the water at the same time, while the impurities in the sewage are temporarily blocked in the water inlet pipe, the other end of the water inlet pipe and the water outlet main pipe are connected obliquely through opening welding, and one end of the water outlet main pipe is provided. It is connected to the solid-liquid separator mentioned above, and the nozzle at the other end is narrowed and fixed to the water outlet check valve. The water outlet check valve is a one-way control valve, which can only flow out sewage and prevent sewage from flowing in the other direction. In, the water outlet check valve is connected to the water outlet flange, the water outlet flange is connected to the water outlet, the solid-liquid separator is connected to the submersible sewage pump, and the solid-liquid The separator is equipped with a backwashing device, and the side wall of the water storage tank is backwashed by the pressure water lifted by the water pump, and part of the sewage flows into the water storage tank through this device when the water enters.

The water pump is arranged in the water storage tank.

One side of the upper part of the water storage tank is provided with a ventilation hole in order to prevent the generation of negative pressure, and the water storage tank is communicated with the outdoor ventilation.

The water storage tank is provided with a liquid level gauge to accurately measure the liquid level of the water storage tank to control the start and stop of the submersible sewage pump.

The lower part of the water storage tank is provided with a channel steel base to fix and support the equipment horizontally.

The upper cover of the water storage tank is movably connected with the tank body.

The submersible pump is operated by a single submersible pump.

The water inlet and the water outlet are on the same side of the water storage tank.

The utility model is that the underground toilet sewage flows into the solid-liquid separator through the water inlet pipeline on one side of the water storage tank. The bottom of the impeller of the pump flows out into the water storage tank, and part of the sewage flows into the water storage tank from the backwash port of the solid-liquid separator. When the water level of the sewage reaches the design water level, the submersible sewage pump starts to lift the sewage in the water storage tank to the outdoor sewage well. When the water level reaches the pump stop water level, the water pump stops running. During the process of sewage being lifted, the particulate debris and garbage intercepted by the water inlet process before the solid-liquid separator will be washed away together with the water flow. At the same time, the backwashing device of the solid-liquid separator will spray pressure water to flush The side wall of the water storage tank plays the role of cleaning the water tank, avoiding artificially cleaning out the sundries deposited in the water storage tank on a regular basis.

In order to avoid that the other side of the water storage tank is affected by the water intake while the water pump is working, the water is specially designed to enter the water on the other side of the water outlet, and a water distributor is designed at the front end of the water inlet pipe, that is, in front of the water inlet check valve, so that even When the water inlet check valve is closed, the sewage can also flow into the water storage tank, and the impurities are temporarily stored in the pipeline. When the water inlet check valve is opened next time, it will enter the solid-liquid separator together with the water flow.

In order to prevent the generation of negative pressure after the submersible sewage pump pumps water, the vent hole on one side of the water storage tank is connected with the outdoor ventilation.

In summary, the utility model has the following beneficial effects:

1. No odor emission, environmental protection and sanitation. movable roof design;

2. There is no need to build a sewage pool: save civil investment costs and facilitate installation;

3. Unique anti-blocking filter design: unique water pump outlet method, water flow automatically rotates;

4. Equipped with an automatic backwash filter device: temporarily separate the dirt and water to avoid separate contact between the dirt and the impeller of the pump and the sewage tank, and the automatic backwash function of the water pump to prevent the deposition of dirt without clearing the water storage tank;

5. The liquid separator is designed outside the water storage tank to avoid large paper scraps and sundries from being blocked in the separator due to human reasons. This design concept is to facilitate the disassembly and installation of the solid-liquid separator, and the maintenance and cleaning of the sundries inside It is more convenient; in addition, the solid-liquid separator is designed outside the water storage tank, which does not occupy the volume of the water storage tank, so that the water storage tank can be designed to be smaller and save cost;

6. Integrated design: simple installation and operation, automatic control, no need for special supervision
