Detailed Description

The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present utility model, based on the embodiments of the present utility model.

Referring to fig. 1 to 3, fig. 1 is a schematic structural view of an embodiment; FIG. 2 is a schematic longitudinal cross-sectional view of an interception net; fig. 3 is a schematic structural view of a lifting frame.

The utility model provides a separation intercepting device for sewage treatment convenient to maintain, includes the inlet channel 1 that closes through wall body or plate body enclosure and sets up the interception net 2 that is arranged in inlet channel 1 to be arranged in intercepting the solid pollutant in the sewage. The interception net 2 specifically comprises a mounting frame 3 and net bodies 4 positioned on two sides of the mounting frame 3, and a lifting frame 5 is arranged between the two net bodies 4 in the mounting frame 3 in a vertically slidable manner.

In a preferred embodiment, slots 6 are formed on both sides of the mounting frame 3, two net bodies 4 are inserted in the two slots 6 in a one-to-one correspondence, a sliding area 8 is further formed between the two net bodies 4, and the material lifting frame 5 is slidably fitted in the sliding area 8.

For ease of illustration and understanding, the web 4 on the side facing the water flow is hereinafter referred to as a first web and the other web 4 is referred to as a second web, for example, the separation and interception device for sewage treatment of the present disclosure may have the following maintenance procedures without limitation:

firstly, the first net body is extracted from the installation frame 3 for blockage removal or replacement, at the moment, solid pollutants intercepted by the first net body can enter the material lifting frame 5 to be blocked by the second net body, and then the first net body after maintenance is reinserted into the installation frame 3. During the replacement of the first net, the solid contaminants carried by the water flow are blocked by the second net. Therefore, the lifting frame 5 can be lifted out of the mounting frame 3, so that the cleaning of solid pollutants is realized, and finally, the second net body can be cleaned and blocked or replaced.

It can be appreciated that if only two net bodies 4 are provided for alternate replacement, the following use problems easily occur:

1. when the first net body is taken out, the solid pollutant blocked by the first net body can be blocked on the second net body, so that after the first net body is put back, if the second net body is directly replaced, the solid pollutant can directly pass through the water inlet channel 1 and enter the sewage treatment equipment at the rear end. Therefore, the solid pollutants blocked by the first net body need to be removed before the first net body is taken out, but it is still unavoidable that the solid pollutants blocked by the second net body leak out during the replacement of the first net body. Or, the cleaning operation can only be carried out before the second net body is taken out, and the maintenance process is time-consuming and labor-consuming, and is inconvenient for taking out and cleaning the solid pollutants.

2. When the second net body is taken out, the second net body can block a certain amount of solid pollutant under the long-term use of the interception net 2, and the part of solid pollutant is easy to leak out of the screen. And in this case still faces the cleaning procedure of the solid contaminating substances blocked via the first net body.

Obviously, the present disclosure can realize maintenance operation without stopping water and leaking sieve through the cooperation of the lifting frame 5 and the two net bodies 4, and the arrangement of the lifting frame 5 is also convenient for the lifting and cleaning operation of solid pollutants from the water surface.

Wherein the top surface of the net body 4 may be provided with a handle 7 to facilitate removal from the mounting frame 3.

In some embodiments, the bottom of the lifting frame 5 also has a receptacle 9. For example, the receiving part 9 is configured to be located below the two net bodies 4, solid pollutants blocked by the second net body can enter the receiving part 9 downwards, and water leakage holes are formed on the bottom surface of the receiving part 9, so that the lifting frame 5 can be lifted out of the water more effectively. In addition, because the solid pollutant actually drifts between the two net bodies 4 through the impact of water flow, in order to facilitate the collection of the solid pollutant, a pressing plate 10 is further arranged in the lifting frame 5 in a vertically slidable manner, and two pull rods 11 extending upwards and penetrating through the lifting frame 5 are also arranged on the pressing plate 10 in an opposite manner. For example, a connecting rod 13 is connected between the two pull rods 11, and a spring 12 is further sleeved on the pull rods 11, one end of the spring 12 abuts against the lifting frame 5, and the other end abuts against the connecting rod 13, so that the pressing plate 10 is kept at a top position higher than the water surface, for example, in a natural state of the spring 12.

Preferably, the pressure plate 10 is also provided with a water leakage hole, and the bottom surface of the pressure plate 10 is also provided with a shutoff rod 14 facing the water leakage hole on the receiving part 9.

When the solid pollutants are cleaned, the connecting rod 13 can be pushed so that the pressing plate 10 presses the solid pollutants between the two net bodies 4 into the receiving part 9, and then the whole lifting frame 5 can be pulled out of the mounting frame 3, and the solid pollutants in the receiving part 9 are cleaned. For example, solid pollutants in the receiving part 9 can be squeezed and removed through the material pressing plate 10, and meanwhile, the plugging rod 14 can be inserted into a corresponding water leakage hole to remove possible plugging.

In a preferred embodiment, the connecting rod 13 is further rotatably provided with a positioning shaft 15, and the lifting frame 5 is correspondingly provided with a positioning hole 16. For example, the positioning hole 16 is a threaded hole, and the positioning shaft 15 can be screwed to the positioning hole 16. Thus, along with the solid pollutants pressed into the receiving part 9 by the pressing plate 10, the positioning shaft 15 is continuously close to the positioning hole 16 until the positioning shaft 15 is fixedly connected with the positioning hole 16 in a threaded manner, and at the moment, the lifting frame 5 can be conveniently pulled out from the mounting frame 3 through the lifting connecting rod 13. In addition, the solid pollutant in the receiving part 9 can be extruded by the pressing plate 10 through continuous screwing of the positioning shaft 15 and the positioning hole 16.

For example, bristles can be further arranged on two side walls of the material pressing plate 10 and are abutted against the corresponding net body 4, so that in the using process of the separation interception device, the net body 4 can be cleaned by the bristles through the drawing connecting rod 13.

The foregoing is merely a preferred embodiment of the utility model, and it is to be understood that the utility model is not limited to the form disclosed herein but is not to be construed as excluding other embodiments, but is capable of numerous other combinations, modifications and environments and is capable of modifications within the scope of the inventive concept, either as taught or as a matter of routine skill or knowledge in the relevant art. And that modifications and variations which do not depart from the spirit and scope of the utility model are intended to be within the scope of the appended claims.
