Description

Integrated lifting pump station with lifting filtering device

Technical Field

The utility model relates to an environment-friendly device field especially relates to sewage treatment, sewage discharge, sewage lifting means field, concretely relates to area lift filter equipment's integration promotion pump station.

Background

The sewage pumping station is an engineering facility for pumping and conveying sewage in the town drainage engineering. When sewage in a sewage pipeline cannot be conveyed or discharged by gravity, or construction is difficult due to the fact that the sewage is buried too deeply in a common channel, or the sewage enters a sewage treatment plant after being positioned at a main pipe terminal and needing to be pumped up, a sewage pump station is required to be arranged.

The sewage pumping station is divided into two types:

one is a pump station which is arranged in a sewage pipeline system and is used for pumping and lifting urban sewage. The sewage pipe has the function of improving the elevation of sewage, because the sewage pipe does not have pressure like a water supply pipe (tap water), the sewage pipe automatically flows by the gravity of the sewage, and because the area of the sewage collected by the urban sewage interception network pipe is wider, the sewage pipe is far away from a sewage treatment plant. The pipeline can not be buried deeply, so a pump station needs to be arranged to improve the elevation of sewage.

And secondly, the device is a pump station which is arranged in a sewage treatment plant and used for lifting sewage and is used for providing water flow power for subsequent processes. Generally, the elevation of wastewater is calculated by subtracting the head loss from the elevation of the tail water discharged after wastewater treatment.

Because the lifting and the transportation of sewage are involved, its operating condition is totally different with the transportation of running water, compares the running water, can mix with a lot of impurity in the sewage, and these impurity will be serious influence the lift pump normal work in the sewage lifting pump station, lead to the jam of pump even. The water inlet of current pump station is provided with fixed filter screen, and this kind of filter screen is immovable, and the space is great, is used for blockking some impurity bigger relatively generally, guarantees normal work through regular manual cleaning. However, because sewage is always stored in the pump station, in the prior art, after the sewage pump works for a period of time, the filter screen arranged at the water inlet is completely exposed, and the sewage pump is cleaned manually. This kind of filtration clearance has inconvenience, and in case take place to block up, does not clear up in time, then sewage just can not smoothly flow into in the glass steel, and simultaneously, great filtration space also can cause great pressure to the pump, is interrupted sewage pump's life.

Example 1:

the embodiment provides an integrated lifting pump station with a lifting filtering device, which is shown in accompanying

drawings

1, 2 and 4 of the specification, and specifically comprises glass fiber reinforced plastics 14 for storing sewage, wherein the glass fiber reinforced plastics 14 are provided with a water inlet 19 for introducing sewage, at least one drain pipe higher than the water inlet 19 for discharging sewage, and at least one submersible pump correspondingly communicated with the drain pipe; the inner wall of the glass fiber reinforced plastic 14 is provided with a filtering device for filtering solid impurities entering the glass fiber reinforced plastic 14 through the water inlet 19, the filtering device comprises a filtering net cage 15, and the filtering net cage 15 drives a transmission device longitudinally arranged along the inner wall of the glass fiber reinforced plastic 14 to move up and down through a driving device arranged at the top of the outer side of the glass fiber reinforced plastic 14. The working principle is as follows: as the basic operating principle of integration promotion pump station and current promotion pump station principle unanimous basically in this embodiment, only on the basis of current promotion pump station, frequently clear up according to the needs that current filtration produced, and the inconvenient problem of clearance optimizes the improvement. The optimized scheme and the working principle have the following technical effects: in the process that sewage enters the glass fiber reinforced plastic 14 from the water inlet 19, the sewage must pass through the filter net cage 15 and solid impurities, the impurities can stay in the filter net cage 15 after being blocked by the filter net cage 15, and the filter net cage 15 can move up and down along the transmission device and has a certain length in the longitudinal direction, so that the impurity storage capacity is good, 360-degree dead angle-free sewage overflow requirements can be met, and the time for regularly cleaning the filter net cage 15 can be prolonged. Compared with the prior art, the effect of directly arranging a filter screen at the water inlet 19 is much better. After more solid sundries are accumulated, the driving device drives the filtering net cage 15 to move upwards along the transmission device, so that the filtering net cage 15 can be lifted up to expose out of the water no matter where the sewage level is, and the cleaning work is more convenient to carry out. Compared with the prior art, the sewage level can be cleaned more conveniently only when the sewage level is controlled to be lower. It is worth explaining that, the inside general conventionality of pump station is provided with stair or cat ladder that are used for the maintainer to go up and down, consequently, adopts the scheme in this embodiment, need not personnel to enter into the deeper position of pump station and just can realize clearing up the debris in the filter box with a net 15. Of course, as a routine arrangement of a person skilled in the art, the filter box 15 may be specially customized, or a detachable or openable window specially used for cleaning sundries may be provided on the filter box 15, which are all small details or small improvements for further improving the sundries cleaning. After clearing up debris, drop filter box 15 again, get back to initial position can, whole cleaning process can generally be accomplished in several minutes, if filter box 15 is last the pertinence be provided with the foreign matter clearance window can be faster, in whole cleaning process, need not operating personnel and enter into the pump station bottom, and is more convenient, also can avoid the suction of the inside harmful gas of pump station simultaneously. If sewage is injected in the cleaning process, the cleaning work cannot be influenced by the injection of the sewage; meanwhile, cleaning personnel can adjust the cleaning time or speed according to the actual condition according to the sewage injection size. If the sewage injection volume of water inlet is big, then can delay the clearance or clear up fast, such advantage is avoided having debris to enter into the pump station during the clearance, and this is common sense to operating personnel in the field, does not do the repeated description. The sewage disposal equipment can be a conventional submersible pump, and the arrangement of the drain pipe can be set according to the conventional arrangement. In this embodiment, the filter device that can move up and down is mainly discussed, and other parts that are the same as or substantially the same as the existing pump station are not described in detail.
