Wastewater treatment equipment for aquatic product retail

Abstract

This utility model discloses a wastewater treatment device for aquatic product retail, including a flotation machine body and a waste residue tank. A filter plate is installed at the top of the inner cavity of the waste residue tank, and a cleaning device is installed at the top of the filter plate. Support plates are installed on the left and right sides of the top of the flotation machine body. Push plates are installed on the front and rear sides of the opposite side of the two support plates, and a driving device is installed on the opposite side of the two push plates. This utility model solves the problem of existing flotation machines, where scrapers typically remove waste residue from the surface of the filtered water and push it into the inner cavity of the waste residue tank.

Description

Technical Field

[0001] This utility model belongs to the technical field of wastewater treatment equipment, and in particular relates to a wastewater treatment equipment for the retail of aquatic products. Background Technology

[0002] Air flotation machines are a common wastewater treatment device in the aquatic product retail industry. They mainly remove impurities and pollutants from wastewater by introducing air or dissolved air water into the wastewater and using microbubbles to adhere to and float suspended solids in the water. Their high efficiency in solid-liquid separation is particularly suitable for treating oily and high-suspended-solid organic wastewater generated during the processing or sale of aquatic products. They are usually used as a pretreatment or deep purification step in conjunction with other processes to improve the possibility of water quality meeting discharge standards or being recycled.

[0003] The problem with existing technology is that when existing air flotation machines are in use, the waste residue on the surface of the filtered water is usually scraped off by a scraper and pushed into the inner cavity of the waste residue tank. However, during the process of pushing the waste residue in, the scraper inevitably brings some water into the inner cavity of the waste residue tank at the same time. The water entering the waste residue tank will dilute the waste residue, resulting in an increase in its water content and increasing the difficulty of dewatering. Utility Model Content

This solves the problem that in the existing air flotation machine, the waste residue on the surface of the filtered water is usually scraped off by a scraper and pushed into the inner cavity of the waste residue tank. However, during the process of pushing the waste residue in, the scraper inevitably brings some water into the inner cavity of the waste residue tank at the same time. The water entering the waste residue tank dilutes the waste residue, resulting in an increase in its water content and increasing the difficulty of dehydration.

[0005] This utility model is implemented as follows: a wastewater treatment device for aquatic product retail includes an air flotation machine body and a waste residue tank. A filter plate is provided at the top of the inner cavity of the waste residue tank, and a cleaning device is provided at the top of the filter plate. Support plates are provided on the left and right sides of the top of the air flotation machine body. Push plates are provided on the front and rear sides of the opposite side of the two support plates. A drive device for cooperating with the cleaning device is provided on the opposite side of the two push plates. Slag discharge holes are provided on the left and right sides of the inner wall of the waste residue tank. Discharge hoppers are provided on the left and right sides of the air flotation machine body. A sliding column for cooperating with the drive device is provided in the middle of the opposite side of the support plates.

[0006] In a preferred embodiment of this invention, the side of the filter plate closest to the inner wall of the waste residue tank is fixedly connected to the inner wall of the waste residue tank, the bottom of the support plate is fixedly connected to the main body of the air flotation machine, and the left and right sides of the sliding column are both fixedly connected to the support plate.

[0007] As a preferred embodiment of this utility model, the left and right sides of the two push plates are fixedly connected to the support plate, and the surfaces of the opposite sides are provided with stroke holes for use with the cleaning device. The position of the discharge hopper corresponds to the slag discharge hole, and the side closer to the main body of the air flotation machine is fixedly connected to the main body of the air flotation machine.

[0010] In a preferred embodiment of this utility model, the bottom of the scraper contacts the filter plate, the bottom of the linkage frame passes through the slide groove and extends to the outside of the slide groove to be fixedly connected to the scraper, the side of the linkage frame near the inner wall of the slide groove contacts the inner wall of the slide groove, the side of the push column near the linkage frame is fixedly connected to the linkage frame, and the side of the push column away from the linkage frame passes through the stroke hole and extends to the inner cavity of the stroke hole to contact the inner wall of the stroke hole.

[0011] In a preferred embodiment of this invention, the left side of the screw is rotatably connected to the support plate, the right side of the screw penetrates the support plate and extends to the outside of the support plate to be fixedly connected to the output end of the servo motor, the left side of the servo motor is fixedly connected to the support plate, the movable plate is threadedly connected to the screw, and the bottom of the movable plate is sleeved on the surface of the sliding column.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model solves the problem that existing air flotation machines, when used in conjunction with a filter plate, cleaning device, support plate, push plate, drive device, slag discharge hole, discharge hopper and sliding column, usually use a scraper to scrape off the waste residue on the surface of the filtered water and push it into the inner cavity of the waste residue tank. However, during the process of pushing the waste residue in, the scraper inevitably brings some water into the inner cavity of the waste residue tank at the same time. The water entering the waste residue tank will dilute the waste residue, resulting in an increase in its water content and increasing the difficulty of dewatering.

[0014] 2. This utility model can separate the water flowing into the waste residue tank with the waste residue by setting a filter plate, thereby reducing the water content of the waste residue. It can also support the drive device by setting a support plate and limit the movement of the moving plate by setting a sliding column.

This utility model, by setting a push plate and a stroke hole, the push plate cooperates with the stroke hole to guide the push column to move along a predetermined trajectory, and drives the scraper to push the waste residue out through the slag discharge hole along the surface of the filter plate. By setting a discharge hopper and a slag discharge hole, the cleaned waste residue can be discharged.

[0016] 4. This utility model, by setting up a cleaning device, can automatically remove waste residue from the surface of the filter plate and push it into the slag discharge hole, ensuring the filter plate's continuous function of separating water flow.

[0017] 5. By providing a driving device, this utility model can drive the cleaning device, making it convenient for users to use the cleaning device.

[0018] 6. This utility model, by setting a scraper, can scrape off the waste residue on the surface of the filter plate. By setting a linkage frame, it can drive the scraper to move. By setting a push column, it can move along the trajectory of the inner cavity of the stroke hole. The linkage frame will drive the scraper to move along the trajectory of the inner cavity of the filter plate, so that the scraper can discharge the waste residue on the top of the filter plate through the slag discharge holes on both sides of the inner wall of the waste residue tank.

[0019] 7. This utility model can drive the moving plate to move by setting a screw, drive the linkage frame to move by setting the moving plate, drive the screw to rotate by setting a servo motor, and limit the linkage frame by setting a sliding groove. Attached Figure Description

[0029] The above scheme is adopted as follows: by setting the filter plate 3, the water flowing into the waste residue tank 2 with the waste residue can be separated, and the water content of the waste residue can be reduced. By setting the support plate 5, the drive device 7 can be supported. By setting the sliding column 10, the moving plate 702 can be limited.

[0033] The above solution is adopted: by setting up the cleaning device 4, the waste residue on the surface of the filter plate 3 can be automatically removed and pushed into the slag discharge hole 8, so as to ensure the continuous water separation function of the filter plate 3.

[0036] refer to Figure 2 and Figure 4 The bottom of the scraper 401 contacts the filter plate 3.

The side of the linkage frame 402 near the inner wall of the slide groove 704 contacts the inner wall of the slide groove 704. The side of the push column 403 near the linkage frame 402 is fixedly connected to the linkage frame 402. The side of the push column 403 away from the linkage frame 402 passes through the stroke hole 11 and extends to the inner cavity of the stroke hole 11 and contacts the inner wall of the stroke hole 11.

[0038] refer to Figure 3 and Figure 4 The left side of the screw 701 is rotatably connected to the support plate 5, the right side of the screw 701 passes through the support plate 5 and extends to the outside of the support plate 5 and is fixedly connected to the output end of the servo motor 703, the left side of the servo motor 703 is fixedly connected to the support plate 5, the moving plate 702 is threadedly connected to the screw 701, and the bottom of the moving plate 702 is sleeved on the surface of the sliding column 10.

[0040] The working principle of this utility model:

[0041] When in use, when the sludge scraping mechanism of the main body 1 of the air flotation machine scrapes the water containing waste sludge into the inner cavity of the waste sludge tank 2, the water and waste sludge fall together on the surface of the filter plate 3. The water flows through the filter plate 3 into the bottom of the inner cavity of the waste sludge tank 2 and is discharged through the drain port set on the side wall of the waste sludge tank 2, while the waste sludge is trapped on its surface by the filter plate 3.

[0042] At the same time, the servo motor 703 is started to run in both forward and reverse directions, driving the screw 701 to rotate. The rotation of the screw 701 drives the moving plate 702, which is threadedly connected to it, to move linearly back and forth along the sliding column 10 fixed between the support plates 5. The moving plate 702 drives the linkage frame 402, which is inserted through the sliding groove 704 on its top, to move synchronously. This, in turn, drives the scraper 401, which is fixed to the bottom of the linkage frame 402, to move synchronously with the linkage frame 402. During the movement, the scraper 401 scrapes off the waste residue on the surface of the filter plate 3.

[0043] At the same time, the linkage frame 402 will drive the push column 403 to move along the trajectory of the inner cavity of the stroke hole 11. During the movement, the push column 403 will drive the scraper 401 to move along the trajectory of the inner cavity of the filter plate 3 through the linkage frame 402. During the movement, the scraper 401 will push the waste residue to the slag discharge holes 8 on both sides of the waste residue trough 2. The waste residue will finally be discharged from the equipment through the discharge hopper 9.

[0044] In summary, this wastewater treatment equipment for aquatic product retail, through the coordinated use of filter plate 3, cleaning device 4, support plate 5, push plate 6, drive device 7, slag discharge hole 8, discharge hopper 9, and sliding column 10, solves the problem that existing air flotation machines typically use scrapers to remove waste residue from the surface of the filtered water and push it into the inner cavity of the waste residue tank. However, during the process of pushing the waste residue in, the scrapers inevitably bring some water into the inner cavity of the waste residue tank simultaneously. The water entering the waste residue tank dilutes the waste residue, leading to an increase in its water content and making dewatering more difficult.
