[0038] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0039] Example 1

[0040] like Figures 1 to 4 As shown, a water treatment device includes a filter tank 1, a filter assembly 2, a flushing assembly 3 and a scraper assembly 4.

[0041] The filter tank 1 has a water storage chamber 11 and a filter chamber disposed on the upper and lower sides, and a through groove 14 connecting the water storage chamber 11 and the filter chamber. Specifically, in this embodiment, the upper and lower sides of the filter tank 1 are separated by a partition 16, thereby forming the water storage chamber 11 and the filter chamber, and the through groove 14 is provided in the middle area of ​​the partition 16. The water storage chamber 11 has a water inlet for water intake. The filter chamber includes a water purification area 12 located directly below the through groove 14 and two receiving areas 13 disposed on the left and right sides of the water purification area 12. Preferably, the two receiving areas 13 are symmetrically arranged. Specifically, in this embodiment, two baffles 15 are provided in the filter chamber, and the filter chamber is separated into the water purification area 12 and the receiving area 13 by the two baffles 15. Preferably, the baffles 15 are vertically arranged. The water purification area 12 has a drain port 121 for draining water outward. The receiving area 13 has a sewage outlet for draining sewage outward (not shown in the figure).

[0042] The filter assembly 2 includes a filter cloth 21 and two winding rollers 22 rotatably disposed in two receiving areas 13. The filter cloth 21 is disposed at the outlet of the through slot 14 to filter the water entering the water purification area 12. The two ends of the filter cloth 21 extend through the water purification area 12 to the receiving areas 13 on both sides and are respectively wound on the corresponding winding rollers 22. Specifically, there is a channel between the baffle 15 and the lower side wall (i.e., the partition 16) of the through slot 14 in this embodiment to allow the filter cloth 21 to pass through, and the two ends of the filter cloth 21 are connected to the winding rollers 22 through the channel. Usually, the channel matches the filter cloth 21 to allow the filter cloth 21 to pass through while reducing the passage of water. After the filter cloth 21 has been used for a period of time, the filtered filter cloth 21 can be wound up by rotating the winding rollers 22 on one side or both sides, and the clean filter cloth 21 will be automatically pulled out to the bottom of the through slot 14. Since the filtered filter cloth 21 is rolled up in the containing area 13 , the impurities, suspended matter, etc. thereon will not pollute the water in the water purification area 12 , thereby ensuring the water quality of the water purification area 12 .

[0043] Furthermore, the two winding rollers 22 are linked by a belt 24. Specifically, the ends of the two winding rollers 22 on the same side are fixedly connected to a pulley 25, and a belt 24 is sleeved on the pulley 25. When one of the two winding rollers 22 is rotated, the other one is synchronously rotated under the drive of the belt 24. Preferably, a driving motor 23 for driving the rotation of one of the two winding rollers 22 is connected to the end thereof, and the driving motor 23 is preferably arranged on the outer wall of the filter tank 1.

[0044] The filter assembly 2 also includes two support rollers 26 disposed in two accommodating areas 13, and one of the support rollers 26 is specifically described. The support roller 26 is located above the winding roller 22, and its extension direction is consistent with the winding roller 22. The support roller 26 specifically includes a support roller body 261 and an elastic layer disposed outside the support roller body 261. The elastic layer makes the filter cloth 21 fit on the lower side wall of the through groove 14, on the one hand, supports the filter cloth 21 to ensure the stability of the movement of the filter cloth 21; on the other hand, it keeps the filter cloth 21 under the through groove 14 in a tensioned state, thereby ensuring the filtering effect.

[0045] The flushing assembly 3 includes a spray head 31 disposed in the accommodating area 13 and facing the filter cloth 21, a connecting pipe connected to the spray head 31, and a high-pressure pump 34 for passing liquid into the connecting pipe. The connecting pipe includes a spray pipe 32 installed on the outer wall or inner wall of the accommodating area 13, and an extension pipe 33 connected to the spray pipe 32 and connectable to a cleaning liquid source. The spray pipe 32 extends along the width direction of the filter cloth 21, and multiple spray heads 31 are evenly distributed thereon. By flushing the used filter cloth 21 with the spray head 31, impurities, suspended matter, etc. on the surface of the filter cloth 21 can be removed, thereby realizing the reuse of the filter cloth 21 and reducing the number of times the filter cloth 21 is replaced. Preferably, the flushing assembly 3 has two groups corresponding to the two ends of the filter cloth 21.

[0046] The scraper assembly 4 has two groups corresponding to the two ends of the filter cloth 21, and one of the groups is taken as an example for specific description. The scraper assembly 4 includes a scraper 41 abutting against the outer side of the filter cloth 21 on the winding roller 22, and the scraper 41 extends along the width direction of the filter cloth 21. The scraper 41 is movably arranged in the accommodating area 13 to allow the winding roller 22 to rotate. The scraper 41 scrapes and cleans the debris on the surface of the filter cloth 21, thereby ensuring the cleaning effect of the filter cloth 21.

[0047] Specifically, the scraper assembly 4 also includes a pipe 43 connected to the baffle 15, a slide bar 44 with one end fixedly connected to the scraper 41 and slidably arranged in the pipe 43, and an elastic member 42 arranged outside the pipe 43. The elastic member 42 abuts between the baffle 15 or the pipe 43 and the scraper 41, so that the scraper 41 always has a tendency to move in a direction close to the filter cloth 21. The scraper 41 is always abutted against the filter cloth 21 by the elastic member 42, which can ensure the scraping and cleaning effect without affecting the movement of the filter cloth 21. The elastic member 42 is preferably an extrusion spring. Further, the pipe 43, the slide bar 44 and the elastic member 42 have at least two groups arranged at the front and rear ends of the scraper 41.

[0048] Working principle:

[0049] The wastewater to be filtered is transported to the water storage chamber 11 of the filter tank 1. The wastewater in the water storage chamber 11 is filtered through the through groove 14 and the filter cloth 21 located at the outlet of the through groove 14 and then enters the water purification area 12 and is discharged from the drain outlet 121 at the bottom of the water purification area 12.

[0050] As the filter cloth 21 filters and removes impurities from the wastewater, the filter cloth 21 is gradually covered with impurities. In order to ensure the filtering and removing impurities effect of the filter cloth 21 on the wastewater, the winding roller 22 on one side is driven to rotate by the driving motor 23. During the rotation of the winding roller 22, the winding roller 22 on the other side is driven to rotate synchronously by the belt 24, thereby driving the filter cloth 21 between the two winding rollers 22 to move, so that the clean filter cloth 21 moves to the bottom of the through groove 14 to continuously filter the wastewater, and the filter cloth 21 after filtering is transferred to the receiving area 13 on one side, and the pump 34 is started to transport the external cleaning liquid to the spray head 31 through the connecting pipe, and the surface of the filter cloth 21 after filtering is rinsed by the spray head 31, and at the same time, the scraper 41 scrapes and cleans the surface of the filter cloth 21. Due to the action of the elastic member 42, the scraper 41 always contacts the surface of the filter cloth 21 during the movement, so that the cleaning effect of the filter cloth 21 is better, and the cleaning liquid in the receiving area 13 can be discharged through the sewage outlet of the receiving area 13.

[0051] When all the clean filter cloth 21 on one side is used, the winding roller 22 is driven by the driving motor 23 to rotate in the opposite direction, so that the filter cloth 21 on the other side that has been cleaned by the flushing component 3 and the scraper component 4 is put into use. Before use, the flushing component 3 can be selectively opened to flush the filter cloth 21 again before putting it into use.

[0052] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
