Description

Technical Field

[0001] The utility model relates to the technical field of sewage filtering equipment, in particular to sewage filtering equipment for aquaculture. Background Art

[0002] In the process of raising livestock, livestock will produce a large amount of breeding wastewater during eating, drinking and excretion. Breeding wastewater contains high concentrations of organic matter, high content of N and P elements and a large number of harmful microorganisms. If the wastewater is discharged directly, it will seriously pollute the environment. Therefore, the relevant departments stipulate that the wastewater must be treated and can only be discharged after it meets the standards. This also derives the livestock breeding wastewater treatment equipment.

[0003] Publication No. CN211411141 U discloses a livestock breeding wastewater treatment device, which includes a mixing box, a motor fixedly connected to the left side of the mixing box, the output shaft of the motor passes through the mixing box and is fixedly connected to a mixing rod, a filter box fixedly connected to the bottom of the mixing box, a drain pipe connected between the filter box and the mixing box, and a solenoid valve is provided on the surface of the drain pipe.

[0004] The existing livestock breeding wastewater treatment device has the following disadvantages: the device is only a single-stage filtration, and the filtration effect is poor, resulting in the treated wastewater still containing some small particles of impurities, and the filter mesh will continue to have dirt stuck in the filter mesh holes during the filtration process, which will affect the normal filtration process of the filter mesh and even cause blockage.

[0019] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0020] like Figures 1 to 4 The filter box 1 is provided with a filter element 2, and a filter element 3 is provided at the bottom of the filter box 1. The filter element 3 is provided with a filter element 4, and a filter element 5 is provided at the top of the filter box 1. The filter element 5 is provided with a filter element 6, and a filter element 6 is provided at the top of the filter box 1. The filter element 5 is provided with a filter element 6, and a filter element 6 is provided at the top of the filter box 1. The filter element 5 is provided with a filter element 6, and a filter element 6 is provided at the filter element 1. The filter element 5 is provided with a filter element 6, and a filter element 6 is provided at the filter element 1. The filter element 5 is provided with a filter element 6, and a filter element 6 is provided at the filter element 1. The filter element 5 is provided with a filter element 6, and a filter element 6 is provided at the filter element 1. A guide plate 9 is fixedly connected, and a sewage storage structure 10 is provided under the guide plate 9. The pushed-out mud and sewage follow the guide plate 9 into the sewage storage structure 10 for unified storage. A fine filter structure 7 is slidably connected inside the filter box 1. The sewage after coarse filtration is filtered again through the fine filter structure 7, thereby filtering out clean water. Ultrasonic vibration devices 11 are provided at both ends of the bottom of the coarse filter 5 and the inside of the fine filter structure 7. The ultrasonic vibration device can be used to make the coarse filter 5 and the fine filter structure 7 generate high-frequency sound wave vibrations during the sewage filtration process through the ultrasonic vibration device 11, thereby preventing impurities in the sewage from clogging the coarse filter 5 and the fine filter structure 7;

[0021] The sewage pushing structure 6 includes a telescopic rod 601, the fixed end of the telescopic rod 601 is fixedly connected to one side of the filter box 1, and the movable end of the telescopic rod 601 extends into the filter box 1 and is located on the top of the coarse filter 5. The movable end of the telescopic rod 601 is fixedly connected to a push plate 602. After the filtration is completed, the push plate 602 is pushed by the telescopic rod 601, so that the push plate 602 pushes the sludge filtered under the top of the coarse filter 5 toward the sewage outlet 4, thereby cleaning the top of the coarse filter 5;

[0022] The fine filter structure 7 includes a through groove 701, which is opened on one side of the filter box 1, and a connecting plate 702 is slidably connected to the through groove 701. The connecting plate 702 is fixedly connected to a fine filter plate 703 on the top of the connecting plate 702 near the inner side of the filter box 1, and the two ends of the bottom of the fine filter plate 703 are fixedly connected to the ultrasonic vibration device 11. An activated carbon filter plate 704 is provided below the fine filter plate 703, and an adsorption plate 705 is provided below the activated carbon filter plate 704. The activated carbon filter plate 704 and the adsorption plate 705 are all fixedly connected to the connecting plate 702. The fine filter plate 703, the activated carbon adsorption plate 704 and the adsorption plate 705 are fixedly installed through the connecting plate. At the same time, the fine filter plate 703, the activated carbon adsorption plate 704 and the adsorption plate 705 can be disassembled and cleaned when used in conjunction with the through groove, which is relatively simple to use. The fine filter plate 703 is used to further filter the sewage after coarse filtration, and the activated carbon adsorption plate 704 and the adsorption plate 705 can be used in conjunction to further clean impurities in the water;

[0023] The baffle structure 8 includes a movable groove 801, which is opened at the bottom of the sewage outlet 4. A number of support springs 802 are fixedly connected in the movable groove 801. A baffle 803 is fixedly connected to the top of the support spring 802. The top of the baffle 803 is close to the inside of the filter box 1. The side is an arc-shaped structure. When the telescopic rod 601 cooperates with the push plate 602 to push the sludge to the sewage outlet 4, it contacts the baffle 803. Since one side of the baffle 803 is an arc-shaped structure, the baffle 803 can be squeezed, thereby causing the baffle 803 to squeeze the support spring 802 and at the same time be retracted into the movable groove 801. After the sludge is discharged, the tension of the support spring 802 resets the top of the baffle 803 to the baffle 803.

[0024] The sewage storage structure 10 includes a support frame 101. The support frame 101 is a U-shaped structure. The support frame 101 is fixedly connected to one end of the filter box 1 close to the guide plate 9 and is located at the bottom of the guide plate 9. A sewage storage box 102 is provided inside the support frame 101. After the sewage is sent out of the filter box 1, the sewage can be sent into the sewage storage box 102 through the guide plate 9. The support frame 101 is used to place the sewage storage box 102.

[0025] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
