DETAILED DESCRIPTION

[0027] In order for those skilled in the art to better understand the utility model, the utility model technical scheme is further described below in combination with the figures and examples.

[0028] As Figures 1-8 shown, the utility model discloses a wastewater filter device, which comprises

[0029] Square sleeve 1, the assembly frame 11 is fixedly installed on both sides of square sleeve 1, two sliding grooves 12 are distributed and opened on the upper portion of the front side of square sleeve 1, and two L-shaped support columns are fixedly installed on the lower portion of the front and rear sides of square sleeve 1.

[0030] Partition 2 is vertically installed in the center of the inside of the square sleeve 1. Partition 2 is located between two sliding grooves 12 and its top is flush with the upper inner wall of the two sliding grooves 12. Partition 2 divides the inside of the square sleeve 1 into a first filter chamber 21 and a second filter chamber 22. Several filter components 23 are arranged inside the first filter chamber 21 and the second filter chamber 22. The specific filter components 23 include a mounting frame 231. Several sealing grooves 232 are opened on both the left and right sides of partition 2. Several connecting grooves 24 are respectively connected to several sealing grooves 232. The mounting frame 231 is slidably and sealingly assembled inside the sealing grooves 232. A square abutment edge 237 is provided on the bottom side of the inside of the mounting frame 231. A filter plate 233 is slidably and sealingly connected inside the mounting frame 231. The bottom of the filter plate 233 abuts against the top of the square abutment edge 237.

[0031] The filter plates 233 on both sides have progressively smaller pore sizes from top to bottom, enabling multi-layer filtration of wastewater. Initially, one filter chamber 21 is used for filtration, while the other filter chamber 22 is closed. One of the closing components 23 is located inside the chute 12. Figure 1 As shown, the left-side sealing component 3 is located inside the chute 12, sealing the first filter chamber 21. When sewage is discharged into the square sleeve 1 through the upper mounting frame 11, since the first filter chamber 21 is sealed, the sewage flows into the second filter chamber 22. After being filtered by multiple filter plates 233 from top to bottom, it is discharged through the lower mounting frame 11. After multi-layer filtration, impurities in the sewage can be effectively filtered. When it is necessary to filter the already used filter plates 233, the operator first pulls the left-side sealing component 3 to open the first filter chamber 21, and then pushes the right-side sealing component 3 into the chute 12 to switch between the first filter chamber 21 and the second filter chamber 22. At this time, the filter plates 233 located inside the first filter chambers 21 continue to perform filtration. The operator pulls out the used mounting frame 231 and takes out the filter plates 233 for cleaning. During this period, there is no need to lift the sewage filter, and the filtration efficiency is high.

[0032] Connecting rods 234 are fixedly installed on the front of several mounting frames 231 on both the left and right sides. Holding rods 235 are fixedly installed on the front ends of several connecting rods 234 on both the left and right sides. Connecting components 236 are provided between the two holding rods 235 and the square sleeve 1. In the initial state, the holding rods 235 are fixedly connected to the square sleeve 1 through the connecting components 236. When it is necessary to clean several filter plates 233 on one side, the connection of the connecting components 236 is released, and the holding rods 235 are pulled out. All the mounting frames 11 on one side can be pulled out, and then the filter plates 233 can be disassembled and cleaned in sequence. After cleaning, several filter plates 233 can be reinstalled. The operation is convenient and quick.

[0033] The left and right parts of the front side of the square sleeve 1 are respectively provided with a plurality of connecting grooves 24 matched with the positions of a plurality of filtering assemblies 23.

[0034] The two closing assemblies 3 are respectively slidingly and sealingly assembled in the two sliding grooves 12.

[0035] In the initial state, one of the closing assemblies 31 is located in the sliding groove 12.

[0036] The upper parts of the left and right sides of the partition plate 2 are respectively provided with working grooves 32, the two sliding grooves 12 are respectively provided with through openings 33 connected with the working grooves 32, the closing assemblies 31 on the side close to each other are respectively fixedly installed with rectangular bars 34 slidingly and sealingly connected with the working grooves 32, and the inner wall of the rear side of the square sleeve 1 is provided with two insertion grooves 35 connected with the two sliding grooves 12.

[0037] The upper part of the front side of the square sleeve 1 is fixedly installed with two mounting blocks 4 arranged in an up-down manner, the side close to each other of the two mounting blocks 4 is jointly rotatably assembled with a gear 41, and the side close to each other of the two rectangular bars 34 is arranged with a plurality of meshing teeth 42.

[0038] As shown in Figure 1 Since the plurality of meshing teeth 42 on the left and right sides are all engaged with the gear 41, when one of the closing assemblies 31 is pulled out, the other closing assembly 31 is driven into the sliding groove through the gear 41 and the meshing teeth 42, and in the process of replacing the closing assembly 31, the other cavity is closed, which is more simple and convenient to operate.

[0039] The locking assembly includes bolts 5. The left sealing plate 31 has several threaded holes 311 on the side away from the gear 41. A fixing block 51 is fixedly installed on the upper left side of the square sleeve 1. The fixing block 51 has a threaded through hole on its left side. Bolts 5 are threaded into the threaded through hole. One end of bolt 5 extends into one of the threaded holes 311 and is threaded into the threaded hole 311. When the left sealing plate 31 is repositioned, after the repositioning is completed, the left sealing plate 31 can be fixed by connecting bolt 5 to one of the threaded holes 311. The operation is convenient and the locking is reliable.

[0040] The device is used as follows:

[0041] When filtering wastewater, only one filter chamber remains operational, while the other filter chamber is sealed using a sealing plate 31. Figure 1 As shown, the first filtration chamber 21 is in a closed state, so sewage is discharged into the second filtration chamber 22 for multi-layer filtration. When the filter plate 233 inside the second filtration chamber 22 needs to be replaced, the operator pulls the left sealing plate 31. At the same time, the right sealing plate 31 is pushed into the right slide groove 12 through the transmission of the gear 41. During this period, both the first filtration chamber 21 and the second filtration chamber 22 are in an open state. Until the left sealing plate 31 is pulled out to the designated position, the right sealing plate 31 will close the second filtration chamber 22, thus changing the first filtration chamber 21 to the working state. The operator can disassemble and replace several filter plates 233 in sequence by simultaneously pulling out several mounting frames 231 by holding the rod 235. During this process, there is no need to stop the sewage filtration, the sewage filtration efficiency is high, and the operation of replacing the filter plate 233 is simple and convenient.

[0042] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
