Description

Technical Field

[0001] The utility model relates to the technical field of crab breeding wastewater treatment, in particular to a crab breeding wastewater treatment device. Background Art

[0002] Crab farming refers to the cultivation of crab seedlings by artificially building breeding ponds, overcoming the problem that crabs only appear seasonally. During the crab farming process, a large amount of wastewater will be generated in the breeding ponds, which will pollute the breeding pond environment and affect the growth of crabs.

[0003] Therefore, a kind of aquaculture wastewater treatment device in the prior art, publication number: CN212631868U, includes a water pool, threaded rods and sliding rods are interspersed horizontally in the water pool, movable blocks are arranged on the threaded rods and sliding rods, and a scraper is fixedly connected to the lower end of the movable block. A No. 1 motor is arranged on one side of the water pool. When cleaning the sludge or debris at the bottom of the water pool, the No. 1 motor and the No. 2 motor can be turned on, and the No. 1 motor drives the threaded rod to rotate, which will cause the threaded rod and the movable block to rotate in a threaded manner, thereby forcing its scraper to move horizontally in the water pool, pushing its sludge to the opening, and at the same time, the No. 2 motor will drive the spiral rod to rotate, so that the sludge entering through the feed port will eventually be discharged to the outside of the water pool through the discharge pipe, and can be transported by a vehicle.

[0004] However, when the scraper moves toward the opening, crabs in the breeding pond may produce a small amount of excrement that falls on the side of the scraper away from the opening. When the scraper moves back to its original position away from the opening, the crab excrement that falls on the side of the scraper away from the opening cannot be effectively processed, that is, it cannot reach the side of the scraper close to the opening, thereby easily causing the excrement to gradually accumulate and be difficult to clean up.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] like Figure 1-4 As shown, a wastewater treatment device for crab breeding comprises a breeding box 1 and a scraper 15 for cleaning excrement arranged at the bottom of the box, a first winding roller 8 is rotatably connected to the outer wall of one side of the breeding box 1, a plurality of first traction lines 12 are wound around the first winding roller 8, a lifting frame 13 which is lifted and lowered along the depth direction of the breeding box 1 is also inserted into the inner wall of the breeding box 1, a screw rod 14 which is threadedly penetrated through the scraper 15 is rotatably connected to the lifting frame 13, and the frame part of the lifting frame 13 also penetrates the scraper 15, the wall of the breeding box 1 on which the first winding roller 8 is installed is also penetrated and fixedly connected with first guide tubes 9 which correspond to the positions and quantities of the plurality of first traction lines 12, one end of the first traction line 12 passes through the first guide tube 9 at the corresponding position and is connected to the lifting frame 13, as shown in FIG. Figure 1As shown, a fixed pipe (not numbered in the figure) for extracting the excrement scraped by the scraper 15 is also installed in the breeding box 1. The internal and external mechanisms of the fixed pipe refer to the fixed pipe in a breeding wastewater treatment device with the publication number CN212631868U. When the scraper 15 is needed to scrape the excrement at the bottom of the breeding box 1, as shown in the figure, the lifting frame 13 is lowered until the bottom edge of the scraper 15 on its surface contacts the bottom of the breeding box 1, and the screw rod 14 is rotated to realize the movement of the scraper 15 toward the fixed pipe, so that the excrement at the bottom of the breeding box 1 is scraped to the fixed pipe for extraction. When the scraper 15 needs to move back and reset, the first winding roller 8 is used to rotate and wind up the first traction line 12, and under the guidance of the first guide tube 9, the lifting frame 13 is lifted to a certain height, so that the bottom edge of the scraper 15 does not contact the bottom of the breeding box 1. Therefore, when the scraper 15 is reset, it will not scrape the excrement that falls on the bottom of the breeding box 1 during the scraping process.

[0024] In order to prevent the excrement stirred at the bottom of the box from diffusing into the water when the scraper 15 moves: a pumping head 16 extending along the length direction of the scraper 15 is fixedly connected to the top edge of one side of the scraper 15, and a pumping pump 10 is also fixedly connected to the outer box wall on one side of the breeding box 1. The water inlet end of the pumping pump 10 extends into the breeding box 1, and a connecting pipe 11 is movably connected to the pumping head 16. When the scraper 15 moves toward the fixed pipe, the pumping pump 10 is started to connect the excrement diffused near the scraper 15 with a part of the water and pump it out along the pumping head 16 and the connecting pipe 11. In addition, it is further explained that the connecting pipe 11 is rotatably connected to the water inlet end of the pumping pump 10 and the port of the pumping head 16, and the connecting pipe 11 is a hose, and the water inlet end of the pumping pump 10 is located in the middle of the breeding box 1, to ensure that the connecting pipe 11 can swing when the scraper 15 drives the pumping head 16 to move back and forth.

[0025] In order to further ensure the smooth crab farming: a lifting filter frame 5 is slidably connected to the box opening of the breeding box 1, and a second winding roller 2 is rotatably connected to the outer box wall on the other side of the breeding box 1, and a plurality of second traction lines 3 are wound around the second winding roller 2, and one end of the plurality of second traction lines 3 extends to be connected to the frame opening of the lifting filter frame 5, and the plurality of second traction lines 3 are divided into two groups of equal number, and the two groups of second traction lines 3 extend to two opposite sides of the frame opening of the lifting filter frame 5, respectively, and one end is evenly distributed and fixed at the frame opening of the lifting filter frame 5, and a plurality of second guide tubes 4 are fixedly connected at the position of each group of second traction lines 3 at the box opening of the breeding box 1, and the second guide tubes 4 are used for the second traction lines 3 to pass through, and the tube openings at both ends are respectively facing the second winding roller 2 and the lifting filter frame 5, and the second winding roller 2 is used to rotate and release the second traction line 3, so that the lifting filter frame 5 can be lowered to a certain depth under the action of its own weight and the weight of the crabs cultured inside, so as to meet the living water depth requirements of crabs during different growth periods:

[0026] In order to ensure the smooth collection of crab excrement: the bottom of the inner frame of the lifting filter frame 5 is detachably installed with a filter plate 6, and the bottom edge of one side of the lifting filter frame 5 and the box wall of one side of the breeding box 1 near the top edge are both hollowed out. The hollow part of the breeding box 1 is hinged with a sealing strip 7. The lifting filter frame 5 and the hollow part of the breeding box 1 are overlapped by the second winding roller 2 rotating and winding the second traction line 3 to realize the lifting of the lifting filter frame 5. After overlap, the filter plate 6 can be exposed to the environment by rotating to open the sealing strip 7, which is convenient for replacement. The significance of replacing the filter plate 6 is that the crabs in different growth periods have different body shapes, and the sizes of the excrement pulled out and the feed particles used for breeding are different. By replacing the filter plate 6 with the corresponding filter hole size, it is ensured that the feed and excrement can pass through the filter plate 6 and the lifting filter frame 5 smoothly. Similarly, it can also prevent crabs with smaller body size from passing through the filter plate 6 and the lifting filter frame 5. In addition, the bottom of the lifting filter frame 5 used in this scheme is also hollowed out, and the hollow aperture is larger than the body size of mature crabs.

[0027] In addition: the second winding roller 2, the first winding roller 8 and the screw rod 14 are all driven by waterproof motors, and the three waterproof motors are respectively installed on both sides of the breeding box 1 and the lifting frame 13.

[0028] Working principle: when it is necessary to clean the excrement at the bottom of the breeding box 1, the motor drives the screw rod 14 to rotate, and the rotation of the screw rod 14 is used to realize the scraper 15 to move toward the fixed pipe, so that the excrement at the bottom of the breeding box 1 is scraped off to the fixed pipe for extraction. When the scraper 15 needs to move back and reset, the motor drives the first winding roller 8 to rotate and wind up the first traction line 12. Under the guidance of the first guide tube 9, the lifting frame 13 is lifted to a certain height, so that the bottom edge of the scraper 15 does not contact the bottom of the breeding box 1. Therefore, when the scraper 15 is reset, it will not scrape the excrement that falls on the bottom of the breeding box 1 during the scraping process.

[0029] The wiring diagram of the motor and the water pump 10 in the present invention is common knowledge in the art, and its working principle is a known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the motor and the water pump 10 are not explained in detail.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
