Description

Technical Field

[0001] This utility model belongs to the field of machinery, and specifically relates to a fishpond water filtration device with a spliced ​​filter screen and brush structure. Background Technology

[0002] Fishponds typically require circulating filtration systems to maintain water cleanliness and prevent fish diseases, such as the automated physical filter for recirculating aquaculture disclosed in invention patent CN201910620734. However, filter screens are prone to damage during use, and a single break necessitates replacing the entire screen, leading to high replacement costs. Furthermore, contaminants adhere to the screen openings during use, and backwashing alone is insufficient to remove them completely, causing a gradual decrease in filtration efficiency. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to provide a fishpond water filtration device with a spliced ​​filter screen and brush structure.

[0004] To solve the above problems, the technical solution of this utility model is:

[0005] A fishpond filtration device with a spliced ​​filter screen and brush structure includes a shell. A partition is fixed on the right side inside the shell. A filtration chamber is formed on the left side of the partition, and a water inlet chamber is formed on the right side. A filter screen cylinder is rotatably connected between the partition and the left side wall of the shell. The filter screen cylinder is driven by a rotating mechanism. The right end of the filter screen cylinder is open. A water inlet pipe is connected to the lower part of the water inlet chamber, and a sewage outlet pipe is connected to the upper part. A V-shaped sewage receiving plate is fixed to the inner side wall of the shell below the sewage outlet pipe. The V-shaped sewage receiving plate extends into the filter screen cylinder. Several backwash nozzles are installed above the filter screen cylinder, and the backwash nozzles face the V-shaped sewage receiving plate. A water outlet pipe is connected to the lower part of the filtration chamber. The filter screen cylinder is formed by splicing several arc-shaped filter screens. The arc-shaped filter screen includes a central arc-shaped filter screen. A surrounding plate is fixed around the arc-shaped filter screen. The surrounding plate has through holes. Adjacent arc-shaped filter screens are fixed by bolts passing through the through holes in the surrounding plate.

[0019] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The embodiments of this application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. Example 1

[0020] like Figure 1 and Figure 2 The fishpond filtration device shown includes a spliced ​​filter screen and brush structure, comprising a shell 1, a partition 2, a filter chamber 3, a water inlet chamber 4, a filter screen cylinder 5, a water inlet pipe 6, a sewage outlet pipe 7, a V-shaped sewage receiving plate 8, an arc-shaped filter screen 9, an arc-shaped filter screen 91, a surrounding plate 92, a brush 10, a lifting cylinder 11, a motor 13, a pinion 14, a gear 15, a suction pipe 17, and a water pump 18.

[0021] The partition 2 is located inside the housing 1, dividing the housing 1 into a filter chamber 3 on the left and a water inlet chamber 4 on the right. A filter screen cylinder 5 is rotatably connected between the partition 2 and the left side wall of the housing 1, and the filter screen cylinder 5 is rotated by a rotating mechanism. The lower part of the water inlet chamber 4 is connected to a water inlet pipe 6, and the upper part is connected to a sewage outlet pipe 7. A V-shaped sewage receiving plate 8 is fixed to the inner side wall of the housing 1 below the sewage outlet pipe 7. The V-shaped sewage receiving plate 8 extends into the filter screen cylinder 5. Several backwash nozzles 16 are installed above the filter screen cylinder 5, and the backwash nozzles 16 face the V-shaped sewage receiving plate 8. The lower part of the filter chamber 3 is connected to a water outlet pipe.

[0022] In operation, water enters through the inlet pipe 6, and the water from the fishpond enters the inlet chamber 4, then gradually flows into the filter cylinder 5. After being filtered by the filter cylinder 5, the water flows out through the outlet pipe below the filter chamber 3. During filtration, the filter cylinder 5 rotates to prevent premature clogging on one side due to prolonged filtration. After a period of time, when the filter holes become clogged to a certain extent, the filter cylinder rotates under the drive of the rotating mechanism to remove the particles and other pollutants left after filtration. The rotation then reaches directly below the backwash nozzle 16, where water sprayed from the backwash nozzle 16 backwashes the filter. The backwash wastewater enters the V-shaped wastewater receiving plate 8 and is discharged through the wastewater outlet pipe 7. The rotating mechanism includes a motor 13, which is connected to a small gear 14. The small gear 14 meshes with a large gear 15, which is fixedly connected to the filter cylinder 5. The backwash nozzle 16 is connected to a suction pipe 17, the bottom end of which is located inside the filter chamber 3. A water pump 18 is installed on the suction pipe 17.

[0023] To prevent excessive replacement costs due to the need to replace the entire filter screen after damage, the filter screen cylinder 5 is formed by splicing together several arc-shaped filter screens 9. The arc-shaped filter screen 9 includes a central arc-shaped filter screen 91, and a surrounding plate 92 is fixed around the arc-shaped filter screen 91. The surrounding plate 92 is provided with through holes, and adjacent arc-shaped filter screens 9 are fixed by bolts passing through the through holes in the surrounding plate 92.

[0024] This way, when one part of the filter is damaged, only the corresponding arc-shaped filter 9 needs to be replaced, thus reducing replacement costs. Example 2

[0025] Based on Example 1, further measures were taken to prevent contaminants from adhering too tightly to the filter screen and becoming difficult to remove.

[0026] A brush 10 is installed above the V-shaped wastewater receiving plate 8 for brushing. Furthermore, to prevent the filter screen 5 from wearing down due to long-term friction between the brush and the filter screen 5, the brush 10 is connected to a lifting cylinder 11, which is fixed to the right side wall of the V-shaped wastewater receiving plate 8 or the housing 1. Example 3

[0027] Based on Example 2, such as Figure 3 As shown, the filter cylinder 5 can be configured as a truncated cone shape, wider on the left and narrower on the right. A brush 10 is installed above the V-shaped wastewater receiving plate 8, with the bristles of the brush 10 adhering to the top inner side of the filter cylinder 5, and the brush 10 is connected to left and right telescopic cylinders 12. This not only increases the filtration area, but also allows the brush bristles to adhere to and separate from the filter cylinder 5 within its extreme stroke range through the telescopic movement of the left and right telescopic cylinders 12.

[0028] The above embodiments are merely one specific implementation of the present utility model and are not intended to limit the present utility model. Any simple improvements and substitutions thereto are within the protection scope of the present utility model.
