Description

Technical Field

[0001] The present invention belongs to the technical field of livestock breeding sewage treatment equipment, and in particular relates to a livestock breeding sewage treatment and discharge device. Background Art

[0002] Currently, most livestock and poultry farms in China generate wastewater from flushing pens. If this wastewater is discharged directly or washed into rivers, lakes, and reservoirs with rainwater, it can easily turn the water black and smelly. This water can then seep into the ground over time, increasing nitrate levels and deteriorating water quality. This seriously pollutes the surrounding environment and groundwater, threatening the health of residents living near the farms. Therefore, it is necessary to utilize sewage treatment and discharge equipment to purify the wastewater generated during livestock farming.

[0003] The existing sewage treatment and discharge device for livestock breeding can filter the sewage, discharge the intercepted solids from the discharge device, and sterilize the screened sewage with drugs before discharging it from the discharge device, thereby achieving the treatment and discharge of sewage. However, after the screening structure easily intercepts a large amount of solids, the existing sewage treatment and discharge device often uses a flat-push cleaning structure to clean the solids intercepted by the screening structure. Although the above-mentioned flat-push cleaning structure can clean most of the solids intercepted by the screening structure, it is often unable to effectively clean some of the solid debris stuck in the sieve holes of the screening structure, and it is easy to cause some of the solids to pass through the sieve holes of the screening structure and fall into the sewage treatment chamber during the pushing process. In addition, as the working time increases, the solids stuck on the screening mechanism will continue to increase, causing most of the sieve holes of the screening structure to be blocked, thereby seriously affecting the efficiency and effect of the subsequent sewage screening treatment of the device.

[0004] For example, the invention with authorization announcement number CN 209702450 U discloses a livestock farm sewage discharge treatment device. In the technical solution of this patent, the solid matter is discharged by using a push rod and a push plate to push the solid matter on the filter mesh layer to the waste residue discharge door and the waste residue discharge pipe. During the discharge process, it is difficult to effectively clean the solid matter stuck on the filter mesh layer, and it is easy to cause some solid matter to pass through the sieve holes into the stirring chamber; and as time goes on, it is easy to affect the subsequent filtration effect and filtration efficiency of the sewage, thereby affecting the treatment efficiency and treatment effect of the sewage.

[0033] like Figure 4 、 6 As shown, a plurality of second telescopic push rods 408 are provided on the inner wall of the processing box 101 at positions corresponding to the clearance holes 403, and the ends of the output shafts of the plurality of second telescopic push rods 408 are also provided with knocking blocks 409 that are adapted to the clearance holes 403 and are used to knock the filter cylinder 108 and are initially located on the inner side of the driven gear 306.

[0034] When livestock breeding water needs to be treated, the livestock breeding wastewater can be added to the treatment box 101 through the water inlet pipe first, and then the wastewater will fall into the filter cartridge 108. The wastewater will directly pass through the filter holes of the filter cartridge 108 and leave the filter cartridge 108 and fall into the water collection bucket 103. Solid dirt will be retained in the filter cartridge 108 because it cannot pass through the filter holes of the filter cartridge 108.

[0035] For the sewage that falls into the water collecting bucket 103, a certain amount of medicine can be added into the water collecting bucket 103 through the medicine adding bucket 201, and the stirring motor 204 is started to rotate the stirring shaft 205 and the stirring blade 206 to stir and mix the mixture of sewage and bactericide in the water collecting bucket 103, thereby sterilizing the sewage in the water collecting bucket 103. After that, the control valve 104 can be opened to discharge the purified sewage from the water collecting bucket 103.

[0036] When enough solid dirt is trapped in the filter drum 108, the slides of the two linear slides 107 can be moved to the right synchronously, so that the filter drum 108 moves to the top of the collecting hopper 105. Then the drive motor 304 can be started, and the filter drum 108 can be rotated and adjusted through the cooperation of the driving gear 305 and the driven gear 306, so that the filter drum 108 is switched from an opening facing upward to an opening facing downward, so that the solid dirt in the filter drum 108 leaves the filter drum 108, falls into the collecting hopper 105 and then leaves the processing box 101.

Through the cooperation of the stirring motor 109, the stirring shaft 110 and the stirring blade 111, the sewage in the filter cartridge 108 can be conveniently stirred, thereby preventing the filter cartridge 108 from having its sieve holes clogged by solid waste when the filter cartridge 108 does not retain enough solid waste, thereby improving the filtration effect of the filter cartridge 108 on the sewage and the duration of a single filtration process.

[0040] According to another embodiment of the present invention, Figure 1As shown, a transparent observation window 501 is further provided at the upper front end of the treatment box 101. Through the transparent observation window 501, the user can conveniently check the situation inside the treatment box 101, for example, the amount inside the water collecting bucket 103, thereby timely draining the sewage in the water collecting bucket 103, and can also check the amount of solid waste trapped in the filter cartridge 108 and conveniently check the position of the filter cartridge 108, thereby timely and conveniently cleaning the solid waste trapped in the filter cartridge 108.
