Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and in particular to a device for cleaning suspended solids in anaerobic fermentation treatment. Background Technology

[0002] The utilization of livestock and poultry waste resources has effectively promoted livestock production and environmental protection. Livestock and poultry manure and wastewater produce biogas through fermentation. Hydraulic biogas production is currently an effective technology for biogas collection and treatment. However, in hydraulic fermentation, a large amount of suspended solids and oily substances are present. These suspended solids may aggregate and form a crust during fermentation, and the oily substances floating on the surface may combine with other substances after oxidation to form a crust. If these suspended solids and oily impurities are not cleaned for a long time, they may cause blockages in pipes and equipment, or easily cause pipe blockages when using micro-sprinkler irrigation systems for fertilization, affecting the operation of the device. Impurities may also negatively impact the quality of the biogas slurry, reducing its reusability. Impurities can also affect the activity of anaerobic microorganisms, reducing fermentation efficiency. Therefore, we propose a device for cleaning suspended solids in anaerobic fermentation treatment to solve the above problems. Utility Model Content

[0003] This invention provides a device for cleaning suspended solids in anaerobic fermentation, which solves the problem that suspended solids may accumulate and form a shell during fermentation, and that oily substances floating on the surface may combine with other substances to form a shell after oxidation. If these suspended solids and oily substances are not cleaned for a long time, they may cause blockage of pipes and equipment, reducing fermentation efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a cleaning device for suspended solids in anaerobic fermentation treatment, including a shell, a partition on the shell, a slag-collecting device at the bottom of the partition, a rotating cleaning device on the slag-collecting device, a slag collection box at the bottom of the slag-collecting device, and tracks on both sides of the slag collection box. The tracks include sliders and slide rails, and the sliders are installed on the slag collection box.

[0005] In the preferred embodiment, a slag discharge port is provided on one side of the shell, and the partition is a hemispherical structure that divides the shell into an overflow chamber and a gas storage chamber.

[0006] In a preferred embodiment, the slag-collecting device includes a bottom ring, an outer ring on the outer wall of the bottom ring, the outer ring being installed on the inner wall of the shell, a plurality of spaced arc-shaped plates on the inner wall of the bottom ring, an arc-shaped boss on the bottom ring, and a bottom groove on the arc-shaped boss.

[0007] In the preferred embodiment, a rotating seat is provided in the middle of the bottom ring, and the rotating seat is connected to the bottom ring through multiple connecting rods. A through hole is provided on the outer ring.

[0008] In a preferred embodiment, the cleaning device includes a bracket, on which a motor is mounted, and on the output shaft of the motor is a connecting rod. One end of the connecting rod is equipped with an L-shaped scraper, and one end of the L-shaped scraper is equipped with an elastic soft plate. The two ends of the elastic soft plate abut against the outer ring and the arc-shaped plate, respectively.

[0009] In a preferred embodiment, the slag collection box includes a box body with multiple filter holes, an opening at the top of the box body, sliding grooves on both sides of the opening, and insert plates on the sliding grooves.

[0010] In the preferred embodiment, racks are provided on both sides of the insert plate, a second gear is provided on the rack, a second motor is provided on the second gear, and the second motor is mounted on the housing.

[0011] In the preferred embodiment, the slide rail has a J-shaped structure, with second slide grooves on both sides of the slide rail. A slide rail rack is provided at the bottom of one side of the second slide groove. Rollers are provided on both sides of the slider, and the rollers abut against the second slide groove. A gear is provided on the slider, and a third motor is provided on the gear. The third motor is installed on the slider, and the gear meshes with the slide rail rack.

[0014] The beneficial effects of this utility model are as follows: the liquid ferments in the gas storage chamber, and the biogas produced enters the bottom of the partition. As the biogas increases, the pressure in the gas storage chamber increases, causing the liquid level in the gas storage chamber to drop. When the biogas liquid drops to the position of the slag receiving device, the stirring device is driven so that the impurities move around the shell under the action of the centrifugal force of the stirring device, so that the impurities float on the bottom ring. The motor of the cleaning device is driven so that the L-shaped scraper rotates, and the L-shaped scraper and the elastic soft plate move the impurities. When the impurities move to the arc-shaped protrusion, the impurities fall from the bottom trough into the slag collection box. When the slag collection box is full, the slag collection box is closed, and the track is driven so that the slider moves the slag collection box. When the slag collection box moves to the top of the slag discharge port, the slider stops moving, the slag collection box is removed from the slider, the slag collection box is opened, and the impurities in the slag collection box are cleaned out.

[0015] The application of slag collection devices, cleaning devices, and slag boxes can promptly and repeatedly remove impurities from the shell, preventing these suspended solids and greases from accumulating and clogging pipes and equipment, thus affecting the operation of the device. It also prevents impurities from forming a crust, which negatively impacts the quality of the biogas slurry, affects the activity of anaerobic microorganisms, reduces fermentation efficiency, and improves gas production efficiency, making it highly valuable for widespread application.

The tracks 7 include a slider 701 and a slide rail 702, with the slider 701 mounted on the slag collection box 6. With this structure, the overflow valve and the discharge valve are closed, and biogas slurry is supplied to the shell 1 through the slag discharge port 101 or a dedicated liquid inlet of the shell 1. The liquid ferments in the gas storage chamber 103, and the generated biogas enters the bottom of the partition 2. As the biogas increases, the pressure in the gas storage chamber 103 increases, causing the liquid level in the gas storage chamber 103 to drop. When the biogas slurry drops to the position of the slag-collecting device 4, the stirring device 8 is activated, causing impurities to move around the shell 1 under the centrifugal force of the stirring device 8, so that the impurities float to the bottom ring 402, and the cleaning device is activated. Motor 502 of 5 rotates L-shaped scraper 504, causing L-shaped scraper 504 and elastic soft plate 505 to move impurities. When the impurities move to the arc-shaped boss 404, they fall from the bottom groove 405 into the slag collection box 6. When the slag collection box 6 is full, the slag collection box 6 is closed, and the drive track 7 drives slider 701 to move the slag collection box 6. When the slag collection box 6 moves to the top of the slag discharge port 101, the slider 701 is stopped, the slag collection box 6 is removed from the slider 701, the slag collection box 6 is opened, and the impurities in the slag collection box 6 are cleaned out.

[0028] The application of the slag collection device 4, cleaning device 5, and slag collection box 6 enables timely and repeated discharge of impurities from the shell 1, preventing these suspended solids and greases from accumulating and clogging pipes and equipment, thus affecting the operation of the device. Simultaneously, it prevents impurities from forming a crust, which negatively impacts the quality of the biogas slurry, affects the activity of anaerobic microorganisms, reduces fermentation efficiency, and ultimately improves gas production efficiency.

[0029] In the preferred embodiment, a slag discharge port 101 is provided on one side of the shell 1, and the partition 2 is a hemispherical structure, which divides the shell 1 into an overflow chamber 102 and a gas storage chamber 103.

An arc-shaped boss 404 is provided on the bottom ring 402, and a bottom groove 405 is provided on the arc-shaped boss 404. With this structure, the stirring device 8 is driven to cause impurities to move around the shell 1 under the centrifugal force of the stirring device 8, causing the impurities to float onto the bottom ring 402. The motor 502 of the cleaning device 5 is driven to rotate the L-shaped scraper 504, causing the L-shaped scraper 504 and the elastic soft plate 505 to move the impurities. When the impurities move onto the arc-shaped boss 404, they fall from the bottom groove 405 into the slag-collecting box 6.

[0031] In a preferred embodiment, a rotating seat 406 is provided in the middle of the bottom ring 402.

In this structure, one end of the connecting rod 503 is connected to the output shaft of the motor 502, and the other end is connected to the L-shaped scraper 504, driving the motor 502 to cause the L-shaped scraper 504 to scrape away impurities on the bottom ring 402. When the L-shaped scraper 504 passes the arc-shaped boss 404, the bottom of the L-shaped scraper 504 scrapes away from the top of the arc-shaped boss 404. The top of the elastic soft plate 505 is connected to the L-shaped scraper 504, but the bottom of the elastic soft plate 505 is not connected to the L-shaped scraper 504. When the L-shaped scraper 504 passes the arc-shaped boss 404, the elastic soft plate 505 sweeps across the arc-shaped boss 404. The two sides of the elastic soft plate 505 abut against the outer ring 401 and the arc-shaped plate 403, respectively.

When the slag collection box 6 moves to the top of the slag discharge port 101, the movement of the slider 701 is stopped, the slag collection box 6 is removed from the slider 701, the slag collection box 6 is opened, and the impurities inside the slag collection box 6 are cleaned out.

[0036] The slide rail 702 has a J-shaped structure. The slide rail rack 703 has the same shape as the slide rail 702. One end of the slide rail 702 is connected to the top of the slag discharge port 101 through a support rod, and the other end of the slide rail 702 is connected to the inner wall of the housing 1 through a second support rod.

[0039] In the preferred embodiment, the partition 2 is equipped with an overflow pipe 9, which has an elbow and an overflow valve. The partition 2 also has an exhaust pipe 3 penetrating the shell 1, with a vent valve on the exhaust pipe 3. With this structure, when there is a large amount of gas in the gas storage chamber 103, the exhaust pipe 3 is opened to release biogas, which can then be used for combustion and power generation. When the liquid level at the slag discharge port 101 or the dedicated liquid inlet of the shell 1 is too high, the overflow valve on the elbow of the overflow pipe 9 is opened to allow the biogas slurry to flow to the upper part of the partition 2. Simultaneously, the overflow pipe 9 allows adjustment of the liquid level inside the shell 1, ensuring that the slag-collecting device 4 is positioned at the top of the liquid surface when impurities need to be removed.
