Description

Technical Field

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

[0002] Slaughterhouses are the main source of meat in today's society. It can be said that human society today cannot do without slaughterhouses. The slaughtering process will produce a certain amount of wastewater, such as dismantling and washing, ground washing and other wastewater. The fat, protein and other substances in these wastewaters are not treated and directly discharged into the water body, which will cause serious eutrophication of the surrounding water bodies, seriously damage the self-destruction ability of the water body, cause the water body to turn black and smelly, and affect the environment and agricultural irrigation.

[0003] When slaughterhouses treat wastewater, they filter it through screens before it enters the septic tank and undergoes aerobic decomposition. However, the effect of screen filtration is not good enough, and slaughterhouses need to set up multiple screens to deal with solid waste of different sizes, which is troublesome. In addition, personnel are required to regularly clean the broken bones, meat pieces, feathers, etc. accumulated on the screens, which is inefficient. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide a slaughterhouse wastewater treatment device to meet the needs of simplifying the slaughterhouse wastewater filtering steps and automatically cleaning solid waste.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is:

[0006] A slaughterhouse wastewater treatment device comprises a filter tank, a sieve plate, a filter residue cleaning mechanism, a slag discharge trough and a guide trough; the sieve plate is fixed on the inner side of the filter tank and is inclined at an acute angle to the horizontal plane; after the slaughterhouse wastewater passes through the sieve plate, it overflows from the guide trough fixed at the tail of the filter tank, and the filter residue on the sieve plate is cleaned into the slag discharge trough by the filter residue cleaning mechanism arranged in the filter tank, and the slag discharge trough is fixed on the top of the filter tank.

[0007] As an improvement, the filter residue cleaning mechanism includes a motor, a second belt roller, a first belt roller, a conveyor belt, a scraper and a rib; the first belt roller is rotatably arranged at the bottom of the filter tank, the second belt roller is mounted and rotatably arranged above the filter tank, and is connected by a motor drive installed and fixed on the outer wall, the first belt roller and the second belt roller are connected by a conveyor belt transmission, and a plurality of scrapers are evenly fixed on the outer surface of the conveyor belt along the circumferential direction, a raised scraper is formed on the side of the scraper facing away from the conveyor belt, and a plurality of raised scrapers are evenly formed along the length direction of the scraper; a plurality of ribs are evenly fixed on the upper side of the screen plate along the left and right directions, thereby forming a plurality of grooves, and the raised scrapers correspond to the grooves one by one and are movably matched. The advantage of such an arrangement is that while separating solids, the water flow channel will not be blocked due to the accumulation of solids.

[0008] As an improvement, the conveyor belt is provided with holes arranged thereon, and the holes can facilitate water circulation.

[0009] As an improvement, it also includes a sedimentation system; the sedimentation system includes a sedimentation tank, a slurry pump, and a pump-slurry pipe. The slurry pump is installed and fixed at the bottom of the sedimentation tank, and the pump inlet is connected to the inner bottom of the sedimentation tank. The pump-slurry pipe is connected to the slurry pump; the sedimentation tank is connected to the filter tank through a diversion trough, and the slaughter wastewater overflowing from the diversion trough flows downward into the sedimentation tank. The sedimentation tank can effectively separate small bones, minced meat, fecal residues and other wastes.

[0010] The advantages of the utility model compared with the prior art are:

[0011] When the utility model is in use, the sieve plate can effectively filter out large-volume or large-particle debris in the slaughterhouse wastewater, and then the heavier small-particle debris in the slaughterhouse wastewater can be further precipitated and separated through the sedimentation system, so that the effective filtration of the slaughterhouse wastewater can be achieved through a simpler structure; and by providing a filter residue cleaning mechanism, and cooperating with the grooves provided on the upper side of the sieve plate, the filter residue accumulated on the sieve plate can be continuously cleaned while the sieve plate is filtering the slaughterhouse wastewater, so that the operation of separating and collecting solid waste from the slaughterhouse wastewater can be automatically completed, saving labor and improving the work efficiency of the preliminary filtration treatment of the slaughterhouse wastewater.
