Description

Technical Field

[0001] The utility model belongs to the technical field of screening, and specifically relates to a novel pollutant screening device. Background Art

[0002] With the increasing number of pig farming, the amount of pig manure has also increased, and the difficulty of manure treatment is becoming more and more serious. If the manure produced by pigs is not treated, it will pollute the environment. At the same time, pig manure contains a large amount of organic matter and nutrients, which are valuable renewable resources. How to treat the manure harmlessly to achieve the goals of reducing, harmless and resource utilization of farming pollution? However, the existing rapid screening device for pollutants cannot distinguish between feces and urine in pig excrement and collect them. At the same time, it is inconvenient to transport feces and urine to rice fields after collection, so it is inconvenient to utilize pig excrement.

[0003] Chinese patent publication number CN116282780A discloses a new type of rapid screening device for pollutants. When in use, the staff installs the mat frame on the ground of the pig farm, and the pigs walk on the support plates. Since there are gaps between the support plates, the gaps are small, so the pigs' feet will not fall into the gaps when they walk on the support plates. When the pigs' excrement is discharged onto the support plates, it falls into the inside of the charging box through the gaps. When there is still excrement remaining on the support plates, the motor works to rotate one of the support plates. Since a rotating rod is fixedly connected to the support plates, and since the two rotating rods are connected by a first pulley, a second pulley, and a first belt, the other support plate rotates during the rotation of one of the support plates, so that the support plates are in an inclined state, thereby facilitating the excrement remaining on the support plates to fall into the inside of the charging box. However, sometimes the excrement of the pigs is relatively viscous and easily adheres to the surface of the support plates. At this time, relying solely on the rotation of the support plates cannot ensure that the excrement can fall into the charging box, resulting in the accumulation of excrement on the surface of the support plates, affecting subsequent screening.

[0004] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] See also Figure 1-5 As shown, in this embodiment, a new type of pollutant screening device is provided, including: an outer frame 1, a material receiving box 2 is provided in the outer frame 1, an isolation plate 13 is connected to the material receiving box 2, the top of the outer frame 1 is connected to a support plate 3, the side wall of the support plate 3 is connected to a second rotating shaft 9, the surface of the second rotating shaft 9 is connected to a worm gear 10, the outer frame 1 is connected to a first rotating shaft 6, and the first rotating shaft 6 passes through the front end of the outer frame 1, the first rotating shaft 6 is connected to a worm 11, a scraper 8, which is located below the support plate 3, the front and rear ends of the scraper 8 are connected to a screw rod 7, and the screw rod 7 passes through the scraper 8, the right end of the screw rod 7 is connected to the motor 5, the left end of the scraper 8 is connected to a nozzle 12, and the right end of the nozzle 12 is connected to the water pipe 4.

[0030] The outer frame 1 provides support and protection for the entire device. The material receiving box 2 is used to collect the screened pollutants. The support plate 3 is located at the top of the outer frame 1, and plays the role of carrying and transporting pollutants. The scraper 8 is located below the support plate 3. It can be moved below the support plate 3 by the drive of the screw rod 7 and the motor 5 to clean the pollutants on the support plate 3. The nozzle 12 is connected to the left end of the scraper 8 and water is supplied through the water pipe 4 to clean the support plate 3. The function of the isolation plate 13 is to divide the space in the material receiving box 2 so as to classify and collect liquid and solid pollutants. By rotating the worm 11, the support plate 3 can be driven to rotate so as to better transport the pollutants to the material receiving box 2.

[0031] In this embodiment, there are multiple support plates 3, and there are gaps between them. An inner cavity is provided on the right side of the outer frame 1. The second rotating shaft 9 passes through the inner cavity and is rotatably connected to the side wall of the inner cavity. The second rotating shaft 9 is located at one end of the inner cavity and is connected to a worm gear 10. The worm 11 is located below the worm gear 10, and the worm 11 is meshed with the worm gear 10.

[0032] The inner cavity provides installation space for transmission components such as the worm wheel 10 and the worm 11. The pigs stand on the support plate 3 and excrete excrement onto the surface of the support plate 3, and the excrement falls into the receiving box 2 through the gap between the support plates 3. At the same time, the worm 11 is driven to rotate by rotating the first rotating shaft 6, and the worm 11 drives the worm wheel 10 to rotate, so that the second rotating shaft 9 is rotated, and then the support plate 3 is rotated, so that the excrement on the surface of the support plate 3 can be better dropped into the receiving box 2.

[0033] A groove is provided below the inner cavity, in which the scraper 8 is located, and the top of the scraper 8 and the bottom of the support plate 3 are on the same horizontal line. The left end of the screw rod 7 is rotatably connected to the left side of the inner wall of the outer frame 1, and the right end of the screw rod 7 passes through the right side wall of the outer frame 1 and is connected to the motor 5. One end of the water pipe 4 passes through the scraper 8 and is connected to the nozzle 12, and the other end passes through the inner cavity and the right side wall of the outer frame 1 in turn and is connected to the external water source, with the water outlet end of the nozzle 12 facing upward.

[0034] When the scraper 8 is not working, it can be moved into the groove to avoid pressing against the support plate 3 and affecting the rotation of the support plate 3. When the excrement on the surface of the support plate 3 is relatively sticky and not easy to fall off, the surface of the support plate 3 is rotated downward, and then the motor 5 is started to drive the screw rod 7 to rotate, so that the scraper 8 moves along the surface of the support plate 3 to clean the excrement on the support plate 3. At the same time, in the process of the scraper 8 cleaning the support plate 3, the nozzle 12 sprays water upward to play a flushing role, and washes down the excrement adhering to the bottom of the support plate 3, thereby improving the cleaning effect. The water flow can also prevent pollutants from accumulating between the scraper 8 and the support plate 3, reducing the wear and resistance of the scraper 8.

[0035] A plurality of filtering holes are provided on the surface of the isolation plate 13 , and a drainage port is provided in the material receiving box 2 .

[0036] When the excrement falls into the collecting box 2, it first contacts the isolation plate 13. The liquid excrement flows through the filter holes to the bottom of the isolation plate 13, while the solid excrement is located on the surface of the isolation plate 13, realizing the solid-liquid separation of the excrement. After the collection is completed, the liquid excrement can be discharged from the drain port.

[0037] Working principle:

[0038] The pigs stand on the support plates 3 to move and defecate. The excrement falls into the receiving box 2 through the gap between the support plates 3 due to gravity. When it is necessary to further promote the falling of excrement, the staff rotates the first rotating shaft 6, and the first rotating shaft 6 drives the worm 11 to rotate. Since the worm 11 is meshed with the worm gear 10, the worm 11 drives the worm gear 10 to rotate, so that the second rotating shaft 9 connected to the worm gear 10 rotates, and then drives the support plate 3 to rotate. The rotation of the support plate 3 makes the excrement on its surface fall into the receiving box 2 better. When the excrement is relatively sticky and not easy to fall, the surface of the support plate 3 is rotated downward, and the motor 5 is started. The motor 5 drives the screw rod 7 to rotate. The rod 7 passes through the scraper 8 and the left end of the screw rod 7 is rotatably connected to the left side of the inner wall of the outer frame 1, and the right end of the screw rod 7 passes through the right side wall of the outer frame 1 and is connected to the motor 5, so the rotation of the screw rod 7 drives the scraper 8 to move along the surface of the support plate 3. During the movement of the scraper 8, the viscous excrement on the support plate 3 is cleaned. At the same time, the nozzle 12 is connected to the external water source through the water pipe 4. During the process of the scraper 8 cleaning the support plate 3, the nozzle 12 sprays water upward to flush the support plate 3. On the one hand, the excrement adhering to the bottom of the support plate 3 can be flushed down, thereby improving the cleaning effect; on the other hand, the water flow can also prevent pollutants from accumulating between the scraper 8 and the support plate 3, thereby reducing the wear and resistance of the scraper 8.

[0039] The present invention is not limited to the above-described embodiments. Any structural changes made under the guidance of the present invention should be understood by anyone. Any technical solution that is the same or similar to the present invention falls within the scope of protection of the present invention. The technology, shape, and structure not described in detail in the present invention are all known technologies.
