[0002] A bar screen is a solid-liquid separation device that can continuously remove impurities from fluids. It is an indispensable special equipment in the production processes of industries such as urban sewage treatment, waterworks, power plant inlets, textiles, food processing, papermaking, and leather. It is a widely used solid-liquid screening device.

[0003] For example, CN219050584U discloses a bar screen cleaning machine, including: a housing; a dispersing component is provided at the upper end of the housing, the dispersing component includes: a through hole, which is opened on the outer side wall of the upper end of the housing; a cover body, which passes through and is slidably connected to the through hole; an electric cylinder, one end of which is disposed inside the cover body; a shaft body, which is disposed at the other end of the electric cylinder; and a perforated plate body, with both ends of the shaft body body passing through the perforated plate body.

[0004] In the existing technology, when separating impurities in water, the bar screen directly scrapes the impurities off and conveys them upwards through a scraper. However, there are different impurities in the water, some of which are irregular in shape and size. During the upward conveying process, they are very easy to roll and fall off. After falling to the bottom, they accumulate and exceed the processing capacity of the bar screen, which can easily cause blockage of the bar screen. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that some impurities are irregular in shape and vary in size, and are very easy to roll off during the upward conveying process, which can easily cause blockage of the bar screen. Therefore, an anti-blockage structure for the bar screen is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a bar screen anti-clogging structure, comprising a bar screen housing, a second cleaning mechanism installed on one side of the bar screen housing, a first cleaning mechanism installed inside the bar screen housing, the first cleaning mechanism comprising a conveying assembly, a connecting shaft fixedly connected between two sets of the conveying assemblies, the end of the connecting shaft being rotatably connected to the inner side of the bar screen housing, an mounting block fixedly connected to one side of each set of the conveying assemblies, a collection frame fixedly connected between the two mounting blocks, a filter plate fixedly connected to one side of the collection frame, and a cleaning scraper fixedly connected to the outside of the collection frame.

[0007] Preferably, guide rods are fixedly connected to both ends of the collection frame, and guide rails are slidably connected to the outside of the guide rods. One side of the guide rails is fixedly connected to the inside of the grid machine housing.

[0008] Preferably, a drive motor is fixedly connected to one side of the bar screen housing, and the output end of the drive motor passes through one side of the bar screen housing and is fixedly connected to one end of one of the connecting shafts.

[0009] Preferably, the second cleaning mechanism includes a fixed frame, one side of which is fixedly connected to one side of the bar screen housing, a fixed plate is fixedly connected to the inner side of the fixed frame, a shifting plate is provided on the inner side of the fixed plate, and a movable push plate is fixedly connected to one end of the shifting plate.

[0010] Preferably, a sliding groove is provided on one side of the shifting plate, and a sliding strip is slidably connected inside the sliding groove. One side of the sliding strip is fixedly connected to the inner side of the fixing plate.

[0011] Preferably, one end of the displacement plate is fixedly connected to a telescopic rod, one end of the telescopic rod is fixedly connected to one side of the fixed plate, and a compression spring is sleeved on the outside of the telescopic rod.

[0012] Preferably, a grating plate is fixedly connected to one side of the grating machine housing.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the drive motor drives the connecting shaft to rotate, which in turn moves the multiple collection frames connected to it. The cleaning scraper removes impurities from one side of the grid plate, and the impurities enter the inside of the collection frame for collection. The filter plate can filter out water, separating the impurities from the water. The collection frame can collect impurities of different sizes, improving the impurity handling capacity of the grid machine shell and preventing large impurities from remaining at the grid plate and causing blockage.

[0015] 2. In this utility model, during the process of the collection frame moving to the top and then moving downward, the impurities inside the collection frame gradually pour out. The tilted moving push plate, fixed plate and shifting plate can guide and collect the poured impurities to prevent them from remaining inside the collection frame and causing blockage. When the collection frame moves downward and contacts the moving push plate, the moving push plate is pushed downward, the telescopic rod retracts, and the compression spring is compressed, so that the shifting plate is housed inside the fixed plate to prevent interference with the downward moving collection frame.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides an anti-clogging structure for a bar screen, including a bar screen housing 1. A second cleaning mechanism 3 is installed on one side of the bar screen housing 1, and a first cleaning mechanism 2 is installed inside the bar screen housing 1. The first cleaning mechanism 2 includes a conveying assembly 24. A connecting shaft 23 is fixedly connected between two sets of conveying assemblies 24. The end of the connecting shaft 23 is rotatably connected to the inner side of the bar screen housing 1. Mounting blocks 28 are fixedly connected to one side of each set of conveying assemblies 24. A collection frame 27 is fixedly connected between the two mounting blocks 28. A filter plate 29 is fixedly connected to one side of the collection frame 27. A cleaning scraper 26 is fixedly connected to the outside of the collection frame 27. Guide rods 25 are fixedly connected to both ends of the collection frame 27. A guide rail 22 is slidably connected to the outside of the guide rods 25. One side of the guide rail 22 is fixedly connected to the inner side of the bar screen housing 1. A drive motor 21 is fixedly connected to one side of the bar screen housing 1. The output end of the drive motor 21 passes through one side of the bar screen housing 1 and is fixedly connected to one end of one of the connecting shafts 23.

[0024] The drive motor 21 drives the connecting shaft 23 to rotate. The conveying assembly 24 consists of two chain wheels and a conveying chain. As the connecting shaft 23 rotates and drives the chain wheels to rotate, the conveying chain moves, which can move multiple connected collection frames 27. The cleaning scraper 26 on one side of the collection frame 27 contacts the grid plate 4 and scrapes off the impurities on one side of the grid plate 4. The impurities enter the inside of the collection frame 27 for collection. As the collection frame 27 rises, the filter plate 29 at the bottom of the collection frame 27 can filter out water, separating the impurities from the water. The guide rods 25 at both ends of the collection frame 27 slide inside the guide rail 22, which makes the movement of the guide rods 25 more stable. The impurities are sent out as the collection frame 27 moves upward. Impurities of different sizes can be collected through the collection frame 27, which improves the impurity handling capacity of the grid machine shell 1 and prevents large impurities from staying at the grid plate 4 and causing blockage.

[0025] Example 2: Figure 1 and Figure 4 As shown, the second cleaning mechanism 3 includes a fixed frame 31, one side of which is fixedly connected to one side of the bar screen housing 1. A fixed plate 34 is fixedly connected to the inner side of the fixed frame 31. A shifting plate 35 is provided on the inner side of the fixed plate 34. A movable push plate 33 is fixedly connected to one end of the shifting plate 35. A sliding groove 32 is provided on one side of the shifting plate 35. A sliding strip 37 is slidably connected inside the sliding groove 32. One side of the sliding strip 37 is fixedly connected to the inner side of the fixed plate 34. A telescopic rod 36 is fixedly connected to one end of the shifting plate 35. One end of the telescopic rod 36 is fixedly connected to one side of the fixed plate 34. A compression spring 38 is sleeved on the outside of the telescopic rod 36. A bar screen 4 is fixedly connected to one side of the bar screen housing 1.

[0026] The overall effect of this embodiment is that, as the collection frame 27 moves to the top and then downwards, the impurities inside the collection frame 27 gradually pour outwards. The tilted movable push plate 33, fixed plate 34, and shift plate 35 can guide the poured impurities. After being guided, the impurities are sent out from the opening at the bottom of the fixed frame 31. When the collection frame 27 moves downwards and contacts the movable push plate 33, the movable push plate 33 is pushed downwards, the sliding bar 37 slides inside the sliding groove 32, the fixed shift plate 35 moves in a straight line, the telescopic rod 36 retracts, and the compression spring 38 is compressed, so that the shift plate 35 is housed inside the fixed plate 34, preventing interference with the downward-moving collection frame 27. At the same time, the impurities collected inside the collection frame 27 are guided and collected, preventing the impurities from remaining inside the collection frame 27.

[0027] The device is used and works as follows: The drive motor 21 drives the connecting shaft 23 to rotate, which in turn moves the multiple collection frames 27. The cleaning scraper 26 scrapes away impurities on one side of the grid plate 4. The impurities enter the collection frame 27 for collection. The collection frame 27 can collect impurities of different sizes. As the collection frame 27 moves to the top and then downwards, the impurities inside the collection frame 27 gradually pour out. The tilted moving push plate 33, fixed plate 34, and shifting plate 35 guide the pouring impurities and send them out. When the collection frame 27 moves downwards and contacts the moving push plate 33, the moving push plate 33 is pushed downwards, and the shifting plate 35 is stored inside the fixed plate 34 to prevent interference with the downward-moving collection frame 27.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
