DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model is further described below in conjunction with embodiments.

[0022] Example: Refer to Figures 1 to 3A wastewater treatment device for aquaculture farms comprises a water tank 1, a water inlet 11 is fixedly installed on the top of the water tank 1, a water outlet 12 is fixedly installed on one side of the water tank 1, a filtering mechanism 2 is arranged inside the water tank 1, a chute 13 is provided on one side of the water tank 1, a plurality of activated carbon filters 3 are slidably connected inside the chute 13, grooves 14 are provided inside the water tank 1 and on both sides corresponding to the bottom of the chute 13, a plurality of springs 15 are fixedly installed on the bottom of the two grooves 14, a top plate 16 is fixedly installed on the other end of the spring 15, and the top plate 16 and the groove 14 are connected to each other. Sliding connection, the top of the top plate 16 contacts the bottom of the activated carbon filter 3, the inside of the water tank 1 is rotatably connected with a rotating shaft 2 4, both ends of the rotating shaft 2 4 are fixedly installed with gears 41, both sides of each gear 41 are meshed with racks 42, and the two racks 42 are slidably connected in the water tank 1, one of the racks 42 is fixedly connected to the side of the top plate 16 close to each other, and a spring 2 43 is fixedly installed between the top of the other rack 42 and the water tank 1, and the sewage is discharged into the inside of the water tank 1 through the water inlet 11 installed on the top, and the sewage in the sewage is first filtered by the filtering mechanism 2. Solid waste is intercepted to prevent it from blocking the activated carbon filter 3 arranged below. Since the top activated carbon filter 3 contacts the sewage first, the first activated carbon filter 3 absorbs the most impurities, and the impurities absorbed by the activated carbon filter 3 below gradually decrease, so that when replacing the activated carbon filter 3, it is only necessary to pull out the first activated carbon filter 3, and the elastic force of the spring 15 pushes the top plate 16 to move upward. When the top plate 16 moves, it drives the rack 42 on one side to move at the same time. Since the rack 42 and the gear 41 are meshed with each other, the other rack 42 drives the top spring 15 to move upward. Spring 2 43 moves downward, further increasing the thrust of the top plate 16, thereby pushing the remaining activated carbon filter 3 to move upward at the same time. At this time, the staff inserts a new activated carbon filter 3 into the bottom of the slide 13. During the movement, the activated carbon filter 3 squeezes the top plate 16 to move it downward until the activated carbon filter 3 completely enters the interior of the water tank 1. At this time, spring 15 and spring 2 43 are both in a compressed state, and at the same time, the top of the top plate 16 contacts the bottom of the lowest activated carbon filter 3, thereby improving the fixing effect of the activated carbon filter 3.

[0023] refer to Figure 3The filtering mechanism 2 includes a servo motor 21 fixedly installed on one side of the water tank 1, and a rotating shaft 22 is rotatably connected to the opposite side of the water tank 1. The output end of the servo motor 21 is fixedly connected to one end of one of the rotating shafts 22, and the two rotating shafts 22 are transmission-connected. A transmission filter 23 is commonly sleeved on the outer sides of the two rotating shafts 22. The transmission filter 23 is located inside the water tank 1, and a sewage tank 24 is fixedly installed on one side of the water tank 1. The transmission filter 23 is connected to the water tank 1, and a sewage pipe 25 is connected to the bottom of the sewage tank 24. The solid garbage in the sewage can be intercepted by the transmission filter 23, and then the servo motor 21 is started, and one of the rotating shafts 22 is driven to rotate through the output end. Since the two rotating shafts 22 are transmission-connected, the two rotating shafts 22 rotate in the same direction, so that the outer transmission filter 23 can be driven to rotate, and the solid garbage on the surface can be transported to the sewage tank 24, thereby preventing the solid garbage from blocking the activated carbon filter 3 arranged below, thereby improving the practicality of the device.

[0024] The water tank 1 is internally rotatably connected with a rotating shaft 3 5, which is transmission-connected to one of the rotating shafts 1 22, and a plurality of scrapers 51 are fixedly mounted on the outer side of the rotating shaft 3 5, and the scrapers 51 are in contact with the conveying filter 23. Since the rotating shaft 3 5 is transmission-connected to one of the rotating shafts 1 22, when the rotating shaft 1 22 rotates, the rotating shaft 3 5 can be driven to rotate at the same time, thereby driving the scrapers 51 on the outer side to rotate, and the scrapers 51 are in contact with the conveying filter 23, so that the solid waste on the surface can be pushed into the sewage tank 24 to avoid blockage.

[0025] The two rotating shafts 22 drive the conveying filter 23 to tilt toward the sewage box 24. A drainage plate 26 is fixedly installed inside the sewage box 24. Since the drainage plate 26 is concave toward the middle, the solid waste entering the sewage box 24 can quickly enter the sewage outlet 25, preventing the solid waste from accumulating inside the sewage box 24.

[0026] refer to Figure 2 One side of the top plate 16 is beveled. Since one side of the top plate 16 is beveled, when replacing the activated carbon filter 3, the top plate 16 can be squeezed to move downward to avoid jamming.

[0027] The activated carbon filter 3 has a T-shaped structure, and the side in contact with water is far away from each other, and the side not in contact with water is made of rubber material and in contact with each other, which can better filter sewage. At the same time, since the side of the activated carbon filter 3 not in contact with water is made of rubber material and in contact with each other, it can achieve a better sealing effect, preventing sewage from flowing out of the gap, thereby improving the sealing effect of the device.

[0028] The operating principle of this embodiment is as follows: when in use, the sewage is discharged into the water tank 1 through the water inlet 11, and the solid garbage in the water is intercepted by the transmission filter 23. At the same time, the servo motor 21 is started to drive one of the rotating shafts 22 to rotate through the output end. Since the two rotating shafts 22 are connected in transmission, the transmission filter 23 can be driven to move, so that it can transfer the intercepted solid garbage to the inside of the sewage box 24, preventing the garbage from accumulating on the surface of the transmission filter 23 for a long time, avoiding affecting the filtering effect of the device, and discharging the solid garbage through the sewage outlet 25 installed at the bottom of the sewage box 24, and then the water is filtered again through the activated carbon filter 3 set at the lower end. Since the activated carbon filter 3 at the top is in contact with the sewage first, it results in the absorption of more impurities. More, while the impurities absorbed by the activated carbon filter 3 below gradually decrease. Therefore, it is necessary to replace the topmost activated carbon filter 3. When replacing, the topmost activated carbon filter 3 is pulled out. At this time, through the cooperation of spring 15, gear 41, rack 42 and spring 2 43, the top plate 16 can push the remaining activated carbon filter 3 to move upward, so that its original position is gradually increased, and then the new activated carbon filter 3 is inserted into the bottom of the slide groove 13. The activated carbon filter 3 squeezes the top plate 16 during the movement until the activated carbon filter 3 completely enters the interior of the water tank 1. At this time, the spring 15 and the spring 2 43 are both in a compressed state, and the top of the top plate 16 contacts with the bottom of the activated carbon filter 3, thereby improving the fixing effect of the activated carbon filter 3.
