Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a beef processing wastewater circulation treatment device. Background Art

[0002] Meat processing wastewater is industrial wastewater discharged during meat processing. It generally includes slaughtering and meat processing. Some also have by-product workshops to produce edible oils, gelatin, soap, etc. The wastewater mainly comes from slaughtering, dehairing, dismantling, opening, cleaning processes, and washing of workshop equipment and floors. The wastewater contains blood, hair, grease, minced meat, impurities, etc.

[0003] The existing technology for treating wastewater generated by beef processing is mostly graded treatment. Large impurities are screened through a conventional screening box, and then some chemical agents are used to precipitate the wastewater, and finally the oil is removed. In the above steps, when the impurities are screened through the sieve plate, the through holes of the sieve plate are easily blocked due to excessive impurities in the wastewater, resulting in reduced wastewater passing efficiency, affecting the efficiency of wastewater treatment, and in the process of mixing the wastewater with the chemical agent to produce precipitation, continuous stirring is required. After a certain period of time, the wastewater is sent out after the precipitation is removed, and then new wastewater is introduced. The overall efficiency of the process is slow, and once blockage occurs, the equipment needs to be stopped to manually clean the filter plate, which is inconvenient. Summary of the invention

In the process, new wastewater can continue to be added and mixed with the wastewater containing the drug solution, thereby improving the efficiency of the precipitation produced by the reaction of fine impurities in the wastewater with the wastewater treatment agent, and will not cause blockage of the internal screen frame and the arc-shaped screen plate.

[0015] Beneficial effects of the present invention:

[0016] 1.

Subsequently, the rear plate can be reset through the spring in the slide frame, and the edges of the front plate and the rear plate are blocked by the sealing ring to prevent sewage from overflowing.

[0020] 5.

At this time, the impurities in the screen frame 11 are concentrated between the inner wall of the water inlet box 1 and the screen frame 11, and the electric push rod 41 drives the connecting plate 42 to move, and then the fixed plate 43 pushes the front plate 45 to enter along one end of the space between the screen frame 11 and the inner wall of the water inlet box 1, and pushes the impurities toward the side of the rear plate 410.

[0032] In this embodiment, the flip assembly 5 also includes a slide plate 52. A slide plate 52 is provided on the outer wall of the water inlet tank 1 between the two tooth plates 55. The two sides of the bottom of the slide plate 52 are rotatably connected with support rods 54 through a rotating shaft, and the other end of the support rod 54 is rotatably connected to the top of the tooth plate 55 through a rotating shaft. A slide groove 53 is opened on the outer wall of the water inlet tank 1, and the back of the slide plate 52 slides along the slide groove 53. A slide frame 57 is fixed on the outer wall of the water inlet tank 1 at a position parallel to the tooth plate 55, and the tooth plate 55 is slidably sleeved on the slide frame 57.

Through the transmission of the first connecting plate 51 and the second connecting plate 59, the rotation of the stirring frame 24 and the reciprocating flipping of the screen frame 11 are synchronized. When the screen frame 11 flips back and forth, the impurities in the wastewater can be screened alternately to avoid all the impurities accumulating on the arc screen plate 13, causing the surface pressure of the arc screen plate 13 to be too large or the impurities to be too much to affect the wastewater passing rate.

[0033] In this embodiment, a motor 23 is fixed on the outer wall of the mixing box 2 at one end away from the turntable 58, and the output end of the motor 23 is fixedly connected to the stirring frame 24.

After the oil removal is completed, it is sent out through the discharge port 31. One of the two outlets at the bottom of the mixing box 2 can be selectively opened. When the delivery pipe 22 corresponding to the inlet end of the water inlet tank 1 is opened, the stirred and mixed wastewater and treatment agent are returned to the inside of the water inlet tank 1 through the suction pump 21, and the impurities are removed by the screen frame 11 and the arc-shaped screen plate 13. This process can be repeated for many times to ensure that the impurities are completely removed. At the same time, new wastewater can be added in this process to merge with the mixed liquid, and the new wastewater is pre-treated. At the same time, the mixing box 2 adds new wastewater treatment agent through the filling port 25 to improve the efficiency of the overall reaction.

[0034] In this embodiment, a sealing plate 12 is provided on the surface of one side of the water inlet box 1 close to the arc sieve plate 13, and a scraper 15 is slidably connected to the surface of the other end of the arc sieve plate 13, and a pull rope 16 is fixed between the scraper 15 and the sealing plate 12, and the scraper 15 and the sealing plate 12 are respectively located at the two ends of the arc sieve plate 13, and the scraper 15 can walk along the surface of the arc sieve plate 13. This structure can be a common groove sliding method, with grooves on both sides of the arc sieve plate 13 or on the inner wall of the water inlet box 1, and the scraper 15 It is connected to the groove, and a spring is arranged in the groove to assist the resetting of the scraper 15. This part of the structure is the prior art, so the sealing plate 12 is opened and not shown in the figure.

[0035] When the device is used, the wastewater generated by beef processing is fed into the top of the water inlet tank 1. When the motor 23 drives the stirring frame 24 to rotate and mix the wastewater and the treatment agent, the turntable 58 rotates with the stirring frame 24, driving the second connecting plate 59 to rotate while pulling the first connecting plate 51 and the slide plate 52 to move vertically back and forth along the slide groove 53, so that the support rods 54 on both sides of the slide plate 52 push the tooth plate 55 to move horizontally and mesh with the gear 56, driving the screen frame 11 to flip 90 degrees and fit the inner wall of the water inlet tank 1. The tooth plate 55 is sleeved on the slide frame 57, so it is guided and limited by the slide frame 57 during translation.

When the screen frame 11 rotates to a vertical state, the screen frame 11 is close to the inner wall of the water inlet box 1, and the screen frame The two sides of 11 are hollowed out. At this time, the impurities in the screen frame 11 are concentrated between the inner wall of the water inlet box 1 and the screen frame 11. The electric push rod 41 drives the connecting plate 42 to move, and then the fixed plate 43 pushes the front plate 45 to enter along one end of the space between the screen frame 11 and the inner wall of the water inlet box 1, pushing the impurities toward the side of the rear plate 410. The top plate 44 first contacts the extrusion plate 48, and the top slider 49 of the extrusion plate 48 slides along the slide frame 47, driving the cross plate 411 and the rear plate 410 to move outward, opening the leakage slot at this position, making it convenient to push out the impurities through the front plate 45, and clean the screen frame 11. Then, the rear plate 410 can be reset through the spring in the slide frame 47. The sealing ring 46 blocks the edges of the front plate 45 and the rear plate 410 to prevent sewage from overflowing. One of the two outlets at the bottom of the mixing box 2 can be selectively opened. When the delivery pipe 22 corresponding to the inlet end of the water inlet tank 1 is opened, the stirred and mixed wastewater and treatment agent are returned to the inside of the water inlet tank 1 through the suction pump 21, and the impurities are removed by the screen frame 11 and the arc-shaped screen plate 13. This process can be repeated for multiple times to ensure that the impurities are completely removed. At the same time, new wastewater can be added in the process to merge with the mixed liquid, and the new wastewater can be pre-treated. At the same time, the mixing box 2 adds new wastewater treatment agent through the filling port 25 to improve the efficiency of the overall reaction.
