Description

Technical Field

[0001] This utility model relates to the field of biogas slurry and biogas residue treatment technology, and in particular to a treatment device for biogas power generation. Background Technology

[0002] After biogas power generation, the anaerobic digestion residue needs to be efficiently separated into solid and liquid components. The treatment device used for biogas power generation can separate biogas residue with low water content, which can be used as raw material for organic fertilizer. At the same time, clear biogas liquid is obtained, which is convenient for subsequent purification and reuse or discharge in compliance with standards, realizing resource utilization and avoiding secondary pollution.

[0003] The existing patent CN219423826U provides a biogas slurry and biogas residue separation device, which adopts a movable scraper design for cleaning the filter screen to prevent clogging.

[0004] However, the device has certain defects in use: when the scraper moves up and down in both directions, it can push the biogas residue out when it moves down, but when it moves up, some biogas residue will remain on the scraper and cannot be completely cleaned, thus affecting the separation efficiency and the stability of continuous operation. Summary of the Invention

[0005] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0006] Therefore, one objective of this utility model is to propose a treatment device for biogas power generation, which uses a unidirectional rolling brush to replace the traditional scraper. When moving downwards, the brush locks and sweeps; when moving upwards, the brush rolls and presses the biogas residue, achieving the dual functions of separation and cleaning, which significantly improves cleaning efficiency and the stability of continuous operation.

[0007] To achieve the above objectives, the first aspect of this utility model provides a processing device for biogas power generation, comprising: an external base, an internal support, a lifting assembly, and a roller brush assembly. The external base has a sloping top, and an inlet pipe is connected to one side of the external base at the top of the slope. The internal support is installed inside the external base, with a discharge trough on the side of the internal support away from the inlet pipe, and a discharge pipe connected to the bottom of the other side. An inclined filter plate is connected to the inner side of the internal support. The lifting assembly is installed on both sides of the external base. The roller brush assembly includes a roller brush frame, a roller brush rod, and a resilient plug. The roller brush frame is slidably installed on the top inner side of the external base and connected to the lifting assembly. The roller brush rod is rotatably installed inside the roller brush frame, with ratchet wheels fixedly installed at both ends. The resilient plug is installed inside both ends of the roller brush frame, and the plug of the resilient plug engages with the ratchet wheels.

[0008] In addition, the processing device for biogas power generation proposed above according to this utility model may also have the following additional technical features: Specifically, the brush holder rises, the ratchet actuates the elastic bolt to retract, the brush rod rotates, the brush holder descends, the ratchet is locked by the elastic bolt, and the brush rod is locked.

[0009] Specifically, the lifting assembly includes a limiting rod, a lead screw, and a motor. The limiting rod is fixedly installed on one side of the external base, the lead screw is rotatably installed on the other side of the external base, the motor is fixedly installed on one side of the external base, and the drive shaft of the motor is connected to one end of the lead screw.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This invention uses a lifting assembly to drive the roller brush assembly to move along the slope of the built-in support, and uses a ratchet mechanism to achieve unidirectional motion control. When the roller brush moves downward, it is locked by the elastic bolt, forming a scraping action to effectively remove the biogas residue on the surface of the filter plate. When it moves upward, the ratchet moves the elastic bolt to retract, and the roller brush rotates automatically. While squeezing the biogas residue to further separate the biogas liquid, it prevents the residue from sticking and achieves efficient self-cleaning.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] The following describes an embodiment of the biogas power generation processing device of the present invention with reference to the accompanying drawings.

[0022] like Figures 1-7 As shown, an embodiment of the present invention provides a processing device for biogas power generation, comprising: an external base 1, an internal support 2, a lifting assembly 4, and a roller brush assembly 5.

[0023] The top of the external base 1 is a slope, and the external base 1 is connected to the feed pipe on one side of the top of the slope.

[0024] The built-in bracket 2 is installed inside the external base 1. The built-in bracket 2 has a discharge trough on the side away from the feed pipe, and a discharge pipe is connected to the bottom of the other side. An inclined filter plate 3 is connected to the inside of the built-in bracket 2.

[0025] It should be noted that the tilt angle of the filter plate 3 is the same as the tilt angle of the top slope of the external base 1.

[0026] It should be noted that the inner bottom of the built-in support 2 is the biogas slurry chamber, and the filtered biogas slurry flows into the biogas slurry chamber. The bottom of the biogas slurry chamber is a slope to help the biogas slurry be discharged from the discharge pipe.

[0027] The lifting assembly 4 is installed on both sides of the external base 1.

[0028] The roller brush assembly 5 includes a roller brush holder 51, a roller brush rod 52, and a resilient plug 55.

[0029] The roller brush holder 51 is slidably installed on the top inner side of the outer base 1. The roller brush holder 51 is connected to the lifting assembly 4. The roller brush rod 52 is rotatably installed on the inner side of the roller brush holder 51. Ratchets 54 are fixedly installed at both ends of the roller brush rod 52. The elastic plug 55 is installed on the inner side of both ends of the roller brush holder 51. The plug of the elastic plug 55 engages with the ratchet 54.

[0030] The brush holder 51 rises, the ratchet 54 moves the elastic plug 55 to retract, the brush rod 52 rotates, the brush holder 51 descends, the ratchet 54 is locked by the elastic plug 55, and the brush rod 52 is locked.

[0031] It should be noted that a brush is installed on the outside of the roller brush rod 52, and a comb tooth 53 is installed on the side of the roller brush frame 51 near the discharge trough. When the roller brush rod 52 rotates, the comb tooth 53 can further clean the brush on the outside of the roller brush rod 52 to prevent the brush from sticking to the biogas residue.

[0032] Specifically, when staff need to perform efficient solid-liquid separation of anaerobic digestion residues, they will use the processing device of this utility model for biogas power generation.

[0033] Anaerobic digestion residue is transported to the surface of filter plate 3 through the feed pipe at the top of the external base 1. Utilizing the continuous slope formed by the external base 1 and the internal support 2, the material naturally slides down under gravity. At this point, some of the biogas slurry passes through the filter plate 3 into the biogas slurry chamber and is discharged and recycled through the discharge pipe, achieving preliminary solid-liquid separation.

[0034] The lifting mechanism drives the roller brush assembly 5 to reciprocate along the slope of the filter plate 3. When the roller brush frame 51 rises, the ratchet 54 at both ends of the roller brush rod 52 engages with the elastic bolt 55, causing the bolt to retract and rotate the roller brush rod 52. The brush squeezes the biogas residue during rolling, further separating residual biogas slurry; simultaneously, the comb teeth 53 clean the brush surface, reducing biogas residue adhesion. When the roller brush frame 51 descends, the elastic bolt 55 resets under the action of the spring and engages the ratchet 54, instantly locking the roller brush rod 52, causing it to drive the brush to scrape the biogas residue towards the discharge trough. Through this cyclical lifting and unidirectional transmission, the system continuously completes the rolling separation of biogas slurry and the directional removal of biogas residue.

[0035] In one embodiment of this utility model, such as Figure 1 and Figure 5 As shown, the lifting assembly 4 includes a limit rod 41, a lead screw 42, and a motor 43.

[0036] The limiting rod 41 is fixedly installed on one side of the external base 1, the lead screw 42 is rotatably installed on the other side of the external base 1, the motor 43 is fixedly installed on one side of the external base 1, and the drive shaft of the motor 43 is connected to one end of the lead screw 42.

[0037] It should be noted that the motor 43 is a servo motor 43 whose speed and rotation direction can be adjusted.

[0038] Specifically, during operation, the motor 43 drives the lead screw 42 to rotate, which is converted into the vertical movement of the roller brush frame 51 along the limit rod 41. By controlling the motor 43 to periodically reverse direction, the roller brush frame 51 can achieve stable reciprocating lifting and lowering along the slope of the filter plate 3, providing continuous and reliable power to the roller brush frame 51.

[0039] In summary, the processing device for biogas power generation of this utility model innovatively introduces a one-way transmission mechanism of ratchet 54 and elastic bolt 55 into the roller brush assembly 5, so that the roller brush rotates and squeezes the biogas residue only during the upward phase to promote liquid-residue separation, and locks and scrapes the biogas residue and pushes it into the discharge chute during the downward phase, thus realizing the dual functions of separation and cleaning in one fell swoop and greatly improving the efficiency of continuous operation.
