Description

Technical Field

[0001] This utility model relates to the field of pump stations, specifically a pump station bar screen cleaning device. Background Technology

[0002] Pollutants in wastewater generally exist in three forms: suspended (including floating), colloidal, and dissolved. The main targets of physical wastewater treatment are suspended solids and some colloidal particles that may clog pump impellers and pipe valves and increase the load on subsequent treatment units. Therefore, physical wastewater treatment is generally also called solid-liquid separation treatment of wastewater. A screen must be installed in front of the wastewater treatment system or pump. The amount of suspended and floating solids (collectively called screenings) that the screen can trap varies greatly depending on the width of the gaps between the selected screen bars and the nature of the wastewater. The screen is the most important auxiliary equipment in a wastewater pumping station. A screen is generally composed of a set of parallel screen bars and is placed at the inlet of the pumping station's collection tank.

[0003] However, although the current pump station screens are equipped with a slag removal mechanism to remove large impurities that clog the screen, a lot of suspended matter tends to adhere and accumulate at the screen bars, which can easily affect the flow of subsequent water.

[0004] In view of the shortcomings of the prior art, this utility model provides a pump station bar screen cleaning device, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a pump station bar screen cleaning device, including a pump station, a bar screen is provided inside the pump station, a slag discharge port is provided above the bar screen on the pump station, a slag guide pipe is installed on the rear surface of the pump station at the position of the slag discharge port, a bar screen cleaning mechanism is installed below the slag guide pipe, the bar screen cleaning mechanism includes: a winding roller, a cleaning plate, and a pressure plate, wiping pads are arrayed on the side of the cleaning plate near the pressure plate corresponding to the position of the bar screen, and a spring is connected between the inside of the wiping pads and the pressure plate.

[0006] As a further improvement of this utility model: a lifting ring is installed on the outer side of the cleaning plate, and a winding rope is connected between the winding roller and the lifting ring.

[0007] As a further improvement of this utility model: a transmission chain is installed inside the pump station, a slag-removing plate is installed on the outside of the transmission chain, and a slag-discharging motor is connected to one end of the transmission chain.

[0012] As a further improvement of this utility model, the slag-removing plate is fixedly connected to the transmission chain.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-4 As shown, this embodiment provides a pump station bar screen cleaning device, including a pump station 1. A bar screen 7 is installed inside the pump station 1. A slag discharge port 8 is located above the bar screen 7 on the pump station 1. A slag guide pipe 2 is installed on the rear surface of the pump station 1 at the slag discharge port 8. A bar screen cleaning mechanism 6 is installed below the slag guide pipe 2. The bar screen cleaning mechanism 6 includes: a winding roller 601, a cleaning plate 605, and a pressure plate 607. Wiping pads are arrayed on the cleaning plate 605 on the side closest to the pressure plate 607, corresponding to the position of the bar screen 7. 609, the cleaning plate 605 and the pressure plate 607 together form a cleaning clamp, and have a large self-weight, so they can fall downwards without the application of tension. The wiping pad 609 is a flexible material component, and the outer diameter of the wiping pad 609 is longer than the inner diameter of the grid plate 7. A spring 608 is connected between the inside of the wiping pad 609 and the pressure plate 607. The pressure plate 607 and the cleaning plate 605 are fixedly connected by the spring 608. One end of the winding roller 601 is located on the outside of the slag guide pipe 2 and a winding motor 603 is installed.

[0022] like Figure 2-3 As shown, in this embodiment, a lifting ring 606 is installed on the outer side of the cleaning plate 605, and a winding rope 604 is connected between the winding roller 601 and the lifting ring 606. A fixed pulley 602 is installed on the lower surface of the slag guide pipe 2 below the winding rope 604. The winding rope 604, the lifting ring 606, and the winding roller 601 are all fixedly connected. A transmission chain 3 is installed inside the pump station 1. A slag-discharging plate 4 is installed on the outer side of the transmission chain 3. A slag discharge motor 5 is connected to one end of the transmission chain 3. The slag-discharging plate 4 is fixedly connected to the transmission chain 3.

[0023] The working principle of this utility model is as follows: When sewage flows from the position of the grating plate 7 towards the slag guide pipe 2, large particles of impurities in the sewage are intercepted and accumulated by the grating plate 7. The slag discharge motor 5 drives the transmission chain 3 to rotate as a whole. The rotating transmission chain 3 drives the slag-discharging plate 4 to move. The slag-discharging plate 4 pushes the impurities accumulated in front of the grating plate 7 upwards, and pushes the impurities to the position of the slag discharge port 8 and into the slag guide pipe 2. When the suspended impurities in the sewage remain on the grating bars after flowing through the grating plate 7, the winding motor 603 drives the winding roller 601 to rotate, winding the rope 6... 04 The winding rope 604 is wound around the outside of the winding roller 601. Under the reversing action of the fixed pulley 602, the cleaning plate 605 is pulled diagonally upward. When the cleaning plate 605 is pulled, it will first be pulled towards the position of the guide slag pipe 2. The control spring 608 is stretched, and at the same time, the wiping pad 609 is pulled from the gap of the grid bar. At the same time, the cleaning clamp is pulled upward, so that the wiping pad 609 wipes the impurities remaining on the grid plate 7. After the force of the winding motor 603 on the winding roller 601 is disconnected, the cleaning plate 605 and the pressure plate 607 fall into the lower position of the grid plate 7 under the overall weight of the cleaning plate 605 and the pressure plate 607.
