Description

Technical Field

[0001] The utility model relates to a device for treating wastewater from aquatic product processing, belonging to the technical field of aquaculture. Background Art

[0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under artificial control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding and management. Wastewater will be generated in the process of aquatic product processing, which requires wastewater treatment equipment to treat the wastewater.

Through the setting of the clamping mechanism, when it is necessary to clean the solid waste on the surface of the filter 2, the top cover 24 of the treatment box 1 can be opened by rotating, and then, the push plate 18 in the clamping mechanism is driven to leave the installation groove 20 at the end of the annular frame 19, thereby releasing the clamping connection between the treatment box 1 and the filter 2. Then, the filter 2 can be taken out of the treatment box 1 to clean the solid waste on the surface of the filter 2 to prevent the solid waste from blocking the filter holes and affecting the filtration of wastewater.

[0032] See also Figure 4 and Figure 5 The outer surface of the end of the push plate 18 is provided with two inclined surfaces, and the push plate 18 drives the two inclined surfaces to penetrate into the installation groove 20, and the ends of the two clamping blocks 23 are pressed on the inclined surfaces.

[0033] See also Figure 5 Two groups of elastic sealing pads are provided on the openings of both the mounting groove 20 and the accommodating cavity 15. The two groups of elastic sealing pads are squeezed together. The setting of the elastic sealing pads can fill the gap between the mounting groove 20 and the accommodating cavity 15 to prevent waste water from flowing into the mounting groove 20 and the accommodating cavity 15.

[0034] See also Figure 1 and Figure 2 A top cover 24 is rotatably provided on the top of the processing box 1, a feed pipe 27 connected to the processing box 1 is provided in the middle of the top cover 24, a discharge pipe 3 is provided at the center of the bottom of the processing box 1, and two supporting legs are provided at the bottom of the processing box 1.

[0035] When in use, the wastewater generated during the aquatic product processing is added into the treatment box 1 through the feed pipe 27 at the top of the treatment box 1, and the wastewater flows into the filter screen 2 and the activated carbon layer 14 inside the treatment box 1. The filter screen 2 will filter the solid waste in the wastewater so that it is located above the filter screen 2, which is convenient for subsequent cleaning. The liquid falls through the filter holes in the filter screen 2, and after being adsorbed by the activated carbon layer 14, it will fall into the inner bottom of the treatment box 1, and then it can be discharged through the discharge pipe 3;

[0036] When it is necessary to clean the solid waste on the surface of the filter screen 2, the top cover 24 of the treatment box 1 is opened by rotating, and then the clamping connection between the treatment box 1 and the filter screen 2 is released by driving the clamping mechanism, and then the filter screen 2 can be taken out of the treatment box 1 to clean the solid waste on the surface of the filter screen 2 to prevent the solid waste from blocking the filter holes and affecting the filtration of wastewater. The operation process of the clamping mechanism is as follows: the bolt 17 on the outside of the treatment box 1 is rotated to make the bolt 17 leave the end of the pull rod 16, and then, under the action of the spring 25, the clamping block 23 moves in the installation groove 20 and squeezes the inclined surface of the push plate 18, and the clamping block 23 will push the push plate 18 to leave the installation groove 20 and return to the accommodating chamber 15. The push plate 18 leaves the installation groove 20, which releases the limit of the filter screen 2. Then, the filter screen 2 can be taken out upwards to clean the solid waste on the surface of the filter screen 2;

[0037] When installing the filter 2, it is only necessary to place the outer side 19 of the new filter 2 on the plurality of positioning blocks 28 on the inner wall of the treatment box 1. At this time, the installation slot 20 on the filter 2 and the push plate 18 are located on the same horizontal axis. At this time, it is only necessary to push the pull rod 16 to drive the push plate 18 to snap into the installation slot 20. At this time, the bolt hole at the end of the pull rod 16 matches the bolt 17 on the fixing frame 29, and the installation of the filter 2 can be completed. Through the design of the clamping mechanism, when installing the filter 2, it is only necessary to push the bolt 17 once to install it to achieve quick installation. When disassembling the filter 2, it is only necessary to remove the bolt 17 once to complete the disassembly. The operation is simple, efficient, convenient and fast.

[0038] When the treatment box 1 is treating wastewater, some impurities or water substances in the wastewater will adhere to the inner wall of the treatment box 1 and continue to breed or grow. At this time, it is necessary to start the inner wall scraping mechanism to clean and scrape the water substances attached to the inner wall of the treatment box 1 to prevent them from adhering to the inner wall of the treatment box 1 and affecting the filtering effect of the wastewater. The operation process of the inner wall scraping mechanism is as follows; by controlling the operation of the motor 5, the motor 5 drives the gear 6 to rotate, and the gear 6 rotates while driving the gear ring 9 meshing therewith to rotate. The rotation of the gear ring 9 drives the annular slider 8, the support ring 10 and the annular guide plate 12 to rotate. The rotation of the support ring 10 will drive the bottom scraper 11 at the bottom end of the support ring 10 to rotate. When the annular guide plate 12 rotates, it will drive the top scraper 13 at the top of the annular guide plate 12 to rotate. Because the shapes of the bottom scraper 11 and the top scraper 13 match and contact the side wall of the treatment box 1, the bottom scraper 11 and the top scraper 13 will scrape the water substances attached to the side wall of the treatment box 1 while rotating to prevent the growth of water substances.

[0039] Because the annular guide plate 12 is an introverted bell-mouth structure, the water material fragments scraped off by the top scraper 13 will fall to the inner bottom of the treatment box 1 under the action of the annular guide plate 12 and stack together with the water material scraped off by the bottom scraper 11, making it convenient for the staff to clean it up uniformly.

[0040] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
