Description

Technical Field

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

[0002] In urban construction and industrial production, sewage pipe networks play a crucial role. Sewage pipe networks are important infrastructure for collecting and transporting sewage. They can concentrate sewage from various sources and transport it to sewage treatment plants for treatment to protect the environment and human health.

[0003] During the operation of sewage pipe networks, slag interception is an important task. Since sewage often contains various solid waste residues, such as branches, plastic bags, sand and stones, if these waste residues are not intercepted, they will enter the sewage treatment plant, increasing the burden on treatment equipment, reducing treatment efficiency, and even possibly damaging the treatment equipment. Therefore, it is necessary to set up slag intercepting devices in sewage pipe networks to intercept and filter the waste residues in the sewage.

[0004] However, traditional slag intercepting equipment has many defects. Traditional slag intercepting equipment usually uses fixed filters to intercept slag. When the filter intercepts a certain amount of waste residues, the filter needs to be taken out for cleaning. During this process, the waste residues in the sewage pipe network are in a state of no interception, resulting in a slag interception gap during this period. This will not only cause a large amount of waste residues to enter the sewage treatment plant, affecting the treatment effect, but also may block the sewage pipe network, causing problems such as sewage overflow. In addition, the process of cleaning waste residues by traditional slag intercepting equipment is relatively cumbersome, requiring a large amount of manpower and time, and reducing the operation efficiency of the sewage pipe network. To solve these problems, the utility model provides a slag intercepting device for a sewage collection pipe network. Summary of the Utility Model

[0005] (1) Technical Problem

[0006] The purpose of the utility model is to provide a slag intercepting device for a sewage collection pipe network to solve the problems that traditional slag intercepting equipment cannot continuously intercept slag and will cause a slag interception gap when cleaning waste residues.

[0007] (2) Technical Content

[0008] To solve the above technical problems, the technical solution of the present utility model is as follows: A slag interception device for a sewage collection pipe network, including a box body with an open upper end, an inlet is provided on the front side of the box body, a drain outlet is provided on the rear side of the box body, the inlet and the drain outlet are diagonally distributed and connected to the sewage pipe network through flanges. An arc-shaped groove is provided inside the box body, a rotating shaft is rotatably provided at the upper end of the box body, and a plurality of slag interception nets are fixedly arranged on the rotating shaft in the circumferential direction of the flue gas. A motor for driving the rotating shaft to rotate is fixedly arranged on the side of the box body. A scraping mechanism is fixedly arranged at one end of the upper end of the box body close to the inlet, and a waste residue collection box is fixedly arranged on the side of the box body close to the scraping mechanism.

[0009] Further, the scraping mechanism includes motors two fixedly arranged on the front and rear sides of the upper end of the box body. A scraping plate is fixedly arranged on the driving shaft of the motor two, and a rubber scraping plate is fixedly arranged on the bottom surface of the scraping plate. The bottom edge of the rubber scraping plate contacts the slag interception net.

[0010] Further, a slag discharge port is provided at the bottom of the side of the waste residue collection box.

[0011] Further, the number of the slag interception nets is four, and the included angle between adjacent slag interception nets is 90°.

[0012] Further, the size of the slag interception net is adapted to the arc-shaped groove.

[0013] Further, the slag interception net divides the internal space of the arc-shaped groove into a slag interception cavity directly communicating with the inlet and a cleaning cavity directly communicating with the drain outlet. The slag interception net rotates inside the arc-shaped groove to intercept and filter out the waste residue from the slag interception cavity.

[0014] (III) Technical effects

[0015] The advantages of the present utility model compared with the prior art are as follows:

[0016] 1. Continuous slag interception function. By setting a plurality of slag interception nets and driving the rotating shaft to rotate by a motor, the slag interception net can continuously rotate in the sewage, realizing continuous slag interception. When a slag interception net intercepts a large amount of waste residue and needs to be cleaned, other slag interception nets are still working, ensuring that the waste residue in the sewage is always intercepted and there will be no slag interception gap when the traditional equipment cleans the waste residue.

[0017] 2. Automatic waste residue cleaning. The device is equipped with a scraping mechanism, including a scraping plate driven by a motor two and a rubber scraping plate. When a certain amount of waste residue accumulates on the slag interception net, the slag interception net is driven to the horizontal state and stopped by the motor, and then the motor two is started. The scraping plate drives the rubber scraping plate to scrape the waste residue from the slag interception net and fall into the waste residue collection box. The entire cleaning process is automatic without manual intervention, greatly improving the cleaning efficiency. Description of the drawings

[0029] The following further describes the present utility model in detail with reference to the accompanying drawings.

[0030] Combined with the attached Figure 1 to the attached Figure 8 , a slag interception device for a sewage collection pipe network, comprising a box body 1 with an open upper end. An inlet 2 is provided on the front side of the box body 1, and a drain outlet 8 is provided on the rear side of the box body 1. The inlet 2 and the drain outlet 8 are diagonally distributed and are connected to the sewage pipe network through a flange 3. An arc-shaped groove 4 is provided inside the box body 1. A rotating shaft 5 is rotatably provided at the upper end of the box body 1. A plurality of slag interception nets 6 are fixedly provided on the rotating shaft 5 in the circumferential direction of the flue gas.

A scraping mechanism is fixedly provided at one end of the upper end of the box body 1 near the inlet 2. A waste residue collection box 9 is fixedly provided on the side of the box body 1 near the scraping mechanism. A slag discharge port 13 is provided at the bottom of the side of the waste residue collection box 9.

[0031] In this embodiment, as a preferred technical solution, the scraping mechanism includes motors two 10 fixedly provided on the front and rear sides of the upper end of the box body 1. A scraping plate 11 is fixedly provided on the driving shaft of the motor two 10. A rubber scraping plate 12 is fixedly provided on the bottom surface of the scraping plate 11.

[0032] In this embodiment, as a preferred technical solution, the number of the slag interception nets 6 is four, and the included angle between adjacent slag interception nets 6 is 90°. The size of the slag interception net 6 is adapted to the arc-shaped groove 4. The slag interception net 6 divides the internal space of the arc-shaped groove 4 into a slag interception chamber 14 directly communicating with the inlet 2 and a cleaning chamber 15 directly communicating with the drain outlet 8. The slag interception net 6 rotates inside the arc-shaped groove 4 to intercept and filter out the waste residue from the slag interception chamber 14.

[0033] The working principle of a slag interception device for a sewage collection pipe network of the present utility model is as follows: The slag interception device for this sewage collection pipe network mainly intercepts the waste residues in the sewage through a rotatable slag interception net 6, and at the same time uses a scraping mechanism to scrape the intercepted waste residues into a waste residue collection box 9, realizing the function of automatically cleaning the waste residues. When sewage enters the box body 1 from the water inlet 2 and passes through the arc-shaped groove 4, the waste residues are intercepted by the rotating slag interception net 6 in the slag interception chamber 14, while the filtered sewage flows into the cleaning chamber 15 and is discharged from the drain port 8. When a certain amount of waste residues accumulates on the slag interception net 6, the motor 7 is started to run the slag interception net 6 to the horizontal state and stop, as Figure 1 , and then the second motor 10 is started to drive the scraping plate 11 and the rubber scraping plate 12 to rotate, scraping the waste residues off the slag interception net 6 and falling into the waste residue collection box 9.

[0034] The working process of a slag interception device for a sewage collection pipe network of the present utility model is as follows:

[0035] 1. Installation: Install this slag interception device in the sewage pipe network through the flange 3 to ensure that the water inlet 2 and the drain port 8 are correctly connected to the sewage pipe network.

[0036] 2. Startup: Connect the power supply and start the motor 7 to drive the rotating shaft 5 to drive the slag interception net 6 to start rotating. At this time, sewage enters the box body 1 from the water inlet 2, and the waste residues are intercepted by the slag interception net 6 in the slag interception chamber 14, and the filtered sewage flows into the cleaning chamber 15 and is discharged from the drain port 8.

[0037] 3. Waste residue cleaning: When the waste residues on the slag interception net 6 accumulate to a certain extent, start the motor 7 to run the slag interception net 6 to the horizontal state and stop, and then start the second motor 10. The second motor 10 drives the scraping plate 11 and the rubber scraping plate 12 to rotate, and the bottom edge of the rubber scraping plate 12 contacts the slag interception net 6, scraping the waste residues off the slag interception net 6 and falling into the waste residue collection box 9.

[0038] 4. Waste residue discharge: When the waste residues in the waste residue collection box 9 accumulate to a certain amount, open the slag discharge port 13 to discharge the waste residues for treatment.

[0039] 5. Continuous operation: During the whole use process, this slag interception device operates continuously to realize continuous interception and automatic cleaning of the waste residues in the sewage, ensuring the normal operation of the sewage pipe network.

[0040] The above describes the present utility model and its implementation manners. Such a description is not restrictive, and what is shown in the drawings is only one of the implementation manners of the present utility model. The actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design, without creative efforts, a structural manner and an embodiment similar to this technical solution without departing from the creative concept of the present utility model, they shall fall within the protection scope of the present utility model.
