Description

An integrated pump station rapid dredging control device

technical field

The utility model relates to a rapid dredging control device for an integrated pumping station, which belongs to the technical field of prefabricated pumping stations.

Background technique

The traditional concrete pumping station has large investment, long construction period, consumes a lot of manpower and material resources, and occupies a large area, which is not conducive to the aesthetic requirements. As a new type of pumping station, the integrated pumping station has been well applied in the project by virtue of its flexibility, short construction period, no land occupation index, and easy installation. The integrated pumping station includes all the elements of the pumping station, which consists of pumps, pipes, valves, instruments, control equipment, stairs and other accessories. The main working principle is as follows: sewage enters into the cylinder of the pumping station through the water inlet pipeline. According to the continuous rise of the liquid level, the water pump system starts. In the process of sewage treatment, the accumulation of sludge inside the cylinder increases with time, resulting in a decrease in the sewage discharge effect. If the impurities deposited at the bottom of the pumping station can not be cleaned up in time, it will endanger the stability and safety of the integrated pumping station. At present, there are still technical bottlenecks for the sludge cleaning device in different operation modes of the integrated pumping station, and it is often difficult to meet the needs of the integrated pumping station to quickly clean up the sludge.

The integrated pumping station is generally equipped with two submersible sewage pumps. In this method, an L-shaped plastic hard pipe is connected under the liquid outlet of the two submersible sewage pumps in the integrated pumping station. A horizontal connecting pipe is added between each L-shaped plastic hard pipe. The water flow impacts the water body inside the cylinder body at the position below the pump body and forms a large-area vortex, which causes strong disturbance to the dirt, silt and scum at the bottom of the cylinder body, so as to achieve the purpose of quickly cleaning the impurities at the bottom of the cylinder. In addition, an automatic control valve is arranged at the horizontal communication pipe and the nozzles of the two L-shaped plastic rigid pipes, and is fixed to the bottom of the cylinder with a bracket. Generally speaking, the operation mode of the integrated pump station has two modes: single pump alternate operation and dual pump simultaneous operation. While dredging the running water pump, with the use of automatic control valve, it can also pre-clean the sludge and impurities at the bottom of another pump that is not running, so as to improve the sewage discharge efficiency of the integrated pump station in different operating modes. , prolong the service life of the pump. This method has novel structure and clear working principle, and uses the combined switch of automatic control valve to achieve the purpose of simple installation and rapid dredging. Compared with the traditional dredging device, the method has the advantages of low cost, high efficiency and remarkable dredging effect, and has high promotion significance.

The sewage flows out of the pump station cylinder through the first water outlet pipe and the second water outlet pipe respectively and enters the subsequent treatment unit .

The utility model has reasonable structure and scientific method. Through the utility model, the integrated pump station rapid dredging control device comprises the following steps:

Step 1), a large amount of sludge impurities enter the cylinder of the pump station and accumulate.

The sewage flows into the inside of the cylinder through the inlet pipe on the side wall of the cylinder of the pump station. With the passage of time of the integrated pump station, a large amount of impurities accumulate in the bottom of the pump station barrel. Especially under the pump body of the submersible sewage pump (including the first submersible sewage pump and the second submersible sewage pump), the accumulation of a large amount of impurities tends to form a water-conducting conical sludge body.

Step 2), connect an L-shaped plastic hard pipe (respectively the first L-shaped plastic hard pipe, the second L-shaped plastic hard pipe).

Each of the two submersible sewage pumps in the integrated pump station is connected with an L-shaped plastic hard pipe below the liquid outlet, and extends it to the position below the pump body, and uses a bracket to fix it on the bottom of the cylinder. When the water pump is started for suction operation, the water flow impacts the water body inside the pump station cylinder at the position below the pump body (the first submersible sewage pump, the second submersible sewage pump) and forms vortices (the first vortex, the second vortex), The dirt, silt and dregs at the bottom of the pumping station cylinder will cause strong disturbance, so as to achieve the purpose of clearing the impurities at the bottom of the cylinder.

Step 3), set up a horizontal connecting pipe to connect 2 L plastic rigid pipes (the first L-shaped plastic rigid pipe and the second L-shaped plastic rigid pipe), and install an automatic control unit on each pipe part Valves (respectively the first automatic control valve and the second automatic control valve).

One automatic control valve, namely 1# valve and 2# valve, is set at each of the two L-shaped plastic hard pipe nozzles. One automatic control valve (the third automatic control valve), namely the 3# valve, is set in the middle of the horizontal communication pipe. Due to the long-term use of the pump station, a large amount of water-conducting conical sludge is easily accumulated under the submersible sewage pump body. At the moment when the pump is turned on, a large amount of impurities pour into the pump body through the pump suction port (liquid inlet), and the submersible sewage pump cannot be cleaned in time, which may easily cause the sewage discharge efficiency of the pump to drop and the pump body to be damaged. Through the rapid dredging control device, the accumulated impurities under the pump can be pre-treated, thereby improving the sewage discharge efficiency.

Step 4), in different operating modes, perform combined control on automatic control valves at different positions.

According to the user's needs or the operation status of the pump station, the pump station can choose different operation modes. For the alternate operation of single pump and simultaneous operation of dual pumps in the pumping station, the rapid dredging control device can improve the sewage discharge efficiency of the pumping station.

①In the single pump alternate operation mode, open the 1# valve, close the 2# valve or close the 1# valve, open the 2# valve, and open the 3# valve in the middle of the horizontal communication pipe at the same time. While dredging the running pump, it can also pre-clean the sludge impurities at the bottom of another pump that is not running, which greatly improves the dredging efficiency.

②In the mode of simultaneous operation of the two pumps, only the 3# valve can be closed to flush and clean the sludge and impurities under the respective pump bodies.

Step 5), liquid flow circulation treatment.

After the sludge deposited at the bottom of the pump station cylinder is stirred, it is sucked by the submersible sewage pump, and the sewage flows out of the pump station cylinder through the water outlet pipes (the first water outlet pipe and the second water outlet pipe) and enters the next unit.

As a further limitation of this method, the 1# valve and the 2# valve need to be arranged at the nozzle of the corresponding L-shaped pipe, and the 3# valve should be arranged at the middle position of the horizontal communication pipe.

As a further limitation of the method, the automatic control valves (the first automatic control valve, the second automatic control valve, and the third automatic control valve) can be combined on and off according to user needs or the operating state of the pump station.

As a further limitation of this method, the diameter of the L-shaped plastic rigid tube (the first L-shaped plastic rigid tube, the second L-shaped plastic rigid tube) is controlled between 60mm and 80mm, and the length of the horizontal connecting tube is adjusted according to the actual pump spacing. Adjustment, generally controlled between 600mm to 800mm.

Beneficial effects, compared with the prior art, the beneficial effects of the present utility model are:

The rapid dredging control device is composed of a rigid plastic pipe, an automatic control valve and a bracket. The installation is simple, the cost is low, the dredging efficiency is high, and it is also convenient for overall processing and production, and can be widely used in integrated pump station projects. Compared with the traditional dredging device, the device focuses on cleaning the sedimentation at the bottom of the integrated pump station, pre-treats the impurity sludge under the non-operating pump, prolongs the service life of the pump, achieves simple installation, convenient operation, and improves sewage efficiency.
