Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a slag intercepting device for a sewage collection pipe network. Background Art

[0002] The sewage pipe network is an important infrastructure of the municipal pipe network system. It is usually laid under the ground of urban roads. The sewage pipe network is used to carry and transport sewage. During the long-term transportation process, there will be a large amount of residue in the pipe. If it is not cleaned in time, it will cause blockage; or before the sewage enters the sewage pipe network, some larger garbage and debris will be filtered and intercepted.

[0003] The existing sewage interception is relatively simple, and most of them are equipped with a filter net at the pipe mouth. In actual situations, a large amount of solid matter will adhere to the filter net, which is prone to cause blockage problems. At the same time, during the cleaning process, the solid matter is pressed on the filter net by the water flow, making it difficult to clean. There are also rotating filter screens that can intercept, collect and centrally store solid matter by rotating continuously. However, this method has high requirements for space occupation and equipment maintenance, and is not suitable for application everywhere. Summary of the invention

[0004] In order to solve the above problems, the present invention discloses a slag blocking device for a sewage collection network, comprising a main structure and a slag blocking mechanism arranged inside the main structure. During implementation, the main structure is buried underground, only the upper end of the main structure is exposed, and both ends of the main structure are connected to sewage pipes respectively.

[0005] The main structure includes a tank body, which is a rectangular parallelepiped structure, and has a sewage inlet and a sewage outlet at both ends. That is, sewage enters the tank body and is pre-treated before being sent out from the sewage outlet. The sewage inlet and the sewage outlet are arranged at the upper part of the tank body to provide a temporary storage space for solid sediments in the sewage, that is, to reduce the discharge of solid matter from the sterile water outlet.

[0006] The slag intercepting mechanism includes an intercepting basket, an opening provided on one side of the intercepting basket is provided facing the sewage inlet, a connecting rod is fixedly connected to the upper part of one side of the intercepting basket, a fixed shaft is inserted through the end of the connecting rod, the fixed shaft is installed inside the tank body, and the fixed shaft is provided near the sewage outlet. Here, sewage enters the interior of the tank body, and solid matter therein passes through the opening of the intercepting basket and enters the interior. The intercepting basket is controlled to rotate around the fixed shaft, so that the solid matter can be dumped out of the intercepting basket, which is convenient for cleaning the intercepted solid matter.

[0007] Support tubes are provided on both sides of the opening, and telescopic rods are provided inside the support tubes. The ends of the telescopic rods are fixedly connected with handles, and the handles are close to the sewage inlet. When cleaning solid objects, the telescopic rods can be pulled out of the support tubes, and the handles can be held. By increasing the length of the lever arm, it is easier to rotate the interception basket.

[0008] Preferably, one end of the fixed shaft is sleeved with a sleeve, the side wall of the sleeve is threadedly connected with a fixing bolt, and one end of the sleeve is matched with a hole reserved on the inner wall of the slot body. This setting is for the assembly between the fixed shaft and the slot body, specifically, one end of the fixed shaft is pre-inserted into the preset hole on the slot body, and then the sleeve at the other end of the fixed shaft is slid so that the sleeve is inserted into the preset hole on the slot body, and finally the fixing bolt is tightened to achieve the fixation between the fixed shaft and the sleeve.

[0009] Preferably, the inner wall of the tank body is fixedly connected with a blocking plate, and the blocking plate is located below the interception basket. Since there is silt in the sewage, the silt begins to sink after entering the tank body, and the blocking plate is set to intercept a large amount of silt on one side of the blocking plate, thereby reducing the silt entering the sewage outlet pipe.

[0010] Preferably, the inner wall of the tank body is fixedly connected with a support block, so that when the slag blocking mechanism is accommodated inside the tank body, the support pipe is placed on the support block. Here, the lower end of the interception basket is not completely in contact with the inner bottom wall of the tank body, that is, there is still a certain flow space below the interception basket. After the solid matter completely blocks the mesh of the interception basket, the ability to discharge sewage can still be maintained, so the support block is set to prevent the bottom of the interception basket from contacting the inner bottom wall of the tank body.

[0011] Preferably, a cover plate is rotatably connected to one side of the upper end of the trough body, and a pry hole is provided in the middle of one side of the cover plate. Under normal circumstances, the cover plate remains in a closed state.

[0012] Preferably, both upper and lower end surfaces of the cover plate are rough surfaces, and the rough surfaces have an anti-slip effect.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. A rotatable interception basket is provided, which can be used to dump out the solid matter trapped in the basket, and has the advantages of simple operation and easy use.

[0015] 2. The overall structure of the present invention is simple, which can reduce the difficulty of construction, and has good stability, which is conducive to later maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figures 1 to 6 As shown, a slag intercepting device for a sewage collection network includes a main structure 1 and a slag intercepting mechanism 2 arranged inside the main structure 1. During construction, a trench is excavated, and the main structure 1 is placed in the trench, and sewage pipes are connected at both ends of the main structure 1. After the sewage passes through the main structure 1, filtering pretreatment is achieved.

[0027] The main structure 1 includes a tank body 11, which is a rectangular parallelepiped structure, and is provided with a sewage inlet 12 and a sewage outlet 15 at the upper part of both ends. That is, the sewage pipe is installed at the sewage inlet 12 and the sewage outlet 15, and the sewage inlet 12 and the sewage outlet 15 are located at the upper part of the tank body 11, and a space for sediment deposition is reserved at the lower part of the tank body 11 to reduce the sediment from entering the sewage outlet 15.

[0028] The slag blocking mechanism 2 includes an interception basket 22. An opening arranged on one side of the interception basket 22 is arranged opposite to the sewage inlet 12. That is, after the sewage enters from the sewage inlet 12, the solid matter in the sewage is blocked and collected by the interception basket 22 to achieve the filtering effect. A connecting rod 23 is fixedly connected to the upper part of one side of the interception basket 22. A fixed shaft 24 is inserted at the end of the connecting rod 23. Through this arrangement, the interception basket 22 can rotate relative to the trough body 11. The fixed shaft 24 is installed inside the trough body 11, and the fixed shaft 24 is arranged close to the sewage outlet 15. When the interception basket 22 accommodates more solid matter, the interception basket 22 is rotated around the fixed shaft 24 to dump the fixed matter onto the ground above the sewage outlet 15.

[0029] Support tubes 21 are provided on both sides of the opening, and telescopic rods 28 are provided inside the support tubes 21. The telescopic rods 28 can be pulled out from the support tubes 21, and the interception basket 22 can be rotated more easily by increasing the lever arm. A handle 27 is fixedly connected to the end of the telescopic rod 28, and the handle 27 is close to the sewage inlet 12. The handle 27 provides a perfect grip feel and can avoid the occurrence of slipping problems.

[0030] One end of the fixed shaft 24 is sleeved with a sleeve 25, and the sleeve 25 can slide axially on the fixed shaft 24. The side wall of the sleeve 25 is threadedly connected with a fixing bolt 26. The fixing bolt 26 is tightened to fix the sleeve 25 on the fixed shaft 25. One end of the sleeve 25 is matched with the hole reserved in the inner wall of the tank body 11. During assembly, one end of the fixed shaft 24 is pre-inserted on the inner wall of the tank body 11, and then the fixed shaft 24 is placed horizontally, and the sleeve 25 is slid, and its end is inserted into the preset hole in the tank body 11, and then the fixing bolt 26 is tightened to achieve the installation of the fixed shaft 24. Furthermore, during the installation of the fixed shaft 24, its interception basket 22 maintains a matching relationship with the fixed shaft 24.

[0031] The inner wall of the tank body 11 is fixedly connected with a blocking plate 14 , which is located below the interception basket 22 and is used to block the silt in the sewage to ensure that a large amount of silt is deposited on one side of the blocking plate 14 instead of entering the sewage outlet 15 .

[0032] The inner wall of the tank body 11 is fixedly connected with a support block 13, and when the slag blocking mechanism 2 is accommodated in the tank body 11, the support pipe 21 is placed on the support block 13. The support block 13 is used to support the slag blocking mechanism 2 to ensure that the position of the slag blocking mechanism 2 is correct.

[0033] A cover plate 18 is rotatably connected to one side of the upper end of the trough body 11. The cover plate 18 plays a protective role, similar to a manhole cover. The device is kept in a closed state when in use. A pry hole 17 is provided in the middle of one side of the cover plate 18. When inspection, maintenance or drainage is required, the cover plate 19 can be pried open using tools such as a crowbar.

[0034] The upper and lower end surfaces of the cover plate 18 are both rough surfaces 16. The provision of the rough surface 16 plays an anti-slip role, and the operator can stand on the rough surface 16 during maintenance or drainage.

[0035] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above technical features.
