The biogas production process generates a large amount of biogas residue, which, if not properly handled, can not only waste resources but also pollute the environment. Traditional biogas residue treatment methods have many drawbacks, such as the extremely low efficiency of manual residue separation, making it difficult to meet the processing needs of large-scale biogas projects.

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] This application discloses a combined biogas and biogas residue recycling device.

[0023] Please see Figure 1 A biogas and biogas residue combined recycling device includes: a base plate 1, a transmission assembly 2 disposed on the top of the base plate 1, a filter assembly 3 located on one side of the transmission assembly 2, and a collection device 4 disposed on the side of the filter assembly 3.

[0024] Please see Figures 2 to 4 The filter assembly 3 includes a vertically arranged first rotating tube 301, a first limiting sleeve 302 sleeved outside the first rotating tube 301, a recovery cylinder funnel 303 fixedly connected to the bottom of the first limiting sleeve 302, a second limiting sleeve 304 disposed at the bottom of the recovery cylinder funnel 303, and a second rotating tube 305 sleeved inside the second limiting sleeve 304. The recovery cylinder funnel 303 is provided with a coarse material filter cylinder 306 and a fine material filter cylinder 307 arranged coaxially. The bottom of the fine material filter cylinder 307 is connected to a filter cylinder funnel 308. A first recovery chamber 309 is formed inside the first rotating tube 301, and a second recovery chamber 310 is formed inside the second rotating tube 305. The top of both the first recovery chamber 309 and the second recovery chamber 310 is provided with a recovery hole 311.

[0025] The filter assembly 3 also includes: a recovery cylinder body 312 surrounding the coarse material filter cylinder 306 and the fine material filter cylinder 307, a discharge pipe 313 connected to the side of the recovery cylinder body 312, a feed pipe 314 disposed at the top of the recovery cylinder body 312, and a booster pump 315 installed at the feed pipe 314; the coarse material filter cylinder 306 and the fine material filter cylinder 307 divide the interior of the recovery cylinder body 312 into three-stage filtration spaces, wherein a raw slurry inlet layer is formed inside the coarse material filter cylinder 306, a coarse slag filtration layer is formed between the coarse material filter cylinder 306 and the fine material filter cylinder 307, and a fine slag filtration layer is formed outside the fine material filter cylinder 307.

[0026] The transmission assembly 2 includes: a bracket 201 fixed on the base plate 1, a motor mounting plate 202 mounted on the bracket 201, a servo motor 203 mounted on the motor mounting plate 202, a drive gear 204 connected to the output end of the servo motor 203, a double rack slider 205 meshing with the drive gear 204, a limiting groove 206 mounted on the double rack slider 205, a longitudinal slide bar 207 penetrating the limiting groove 206, a first driven gear 208 and a second driven gear 209 meshing with both sides of the double rack slider 205 respectively, the first driven gear 208 being fixedly connected to the first rotating tube 301, and the second driven gear 209 being fixedly connected to the second rotating tube 305.

[0027] The coarse material filter cartridge 306 has a filter pore diameter of 2-5mm, and the fine material filter cartridge 307 has a filter pore diameter of 0.5-1mm. The filter pores of the coarse material filter cartridge 306 and the fine material filter cartridge 307 are staggered.

[0028] The bottoms of the first recovery chamber 309 and the second recovery chamber 310 are both connected to the collection device 4 through pipes, and the recovery cylinder funnel 303 is fixedly installed at the bottom of the recovery cylinder body 312 through a flange structure.

[0029] Further explanation is needed:

[0030] In the biogas and sludge combined recycling device, the transmission component 2 plays a key role in power transmission and motion conversion. The servo motor 203 serves as the power source, and its output rotational force is transmitted to the double rack slider 205 through the drive gear 204, causing it to generate linear motion. This motion is then precisely converted into the rotation of the first rotating tube 301 and the second rotating tube 305 through the meshing of the double rack slider 205 with the first driven gear 208 and the second driven gear 209. The bracket 201 and the motor mounting plate 202 provide stable support for each component. The limiting groove 206 and the longitudinal slide bar 207 ensure that the movement direction of the double rack slider 205 is accurate, ensuring that the entire transmission process is efficient, stable and precise, providing power support for the operation of the filter component 3.

[0031] The filter assembly 3 is the core component for the joint recovery of biogas and biogas residue. The raw slurry enters the recovery cylinder body 312 from the feed pipe 314 under the action of the booster pump 315. It first passes through the coarse material filter cylinder 306 to initially filter coarse residue with a pore size of 2-5mm, and then passes through the fine material filter cylinder 307 to further filter fine residue with a pore size of 0.5-1mm. The staggered distribution of filter holes improves the filtration effect. The filtered material is guided to the second rotating pipe 305 through the recovery cylinder funnel 303. The first recovery chamber 309 and the second recovery chamber 310 in the first rotating pipe 301 and the second rotating pipe 305 respectively collect the filtered material at different stages through the top recovery hole 311, realizing efficient multi-stage filtration and classified recovery of biogas and biogas residue, and improving resource utilization.

[0032] The working principle of the above embodiments is as follows:

[0033] First, when the equipment is started, the transmission component 2 comes into play, the servo motor 203 is powered on and runs, and its output rotational power is transmitted to the double rack slider 205 via the drive gear 204. The double rack slider 205 starts to move in a straight line, and then through meshing with the first driven gear 208 and the second driven gear 209, the straight line motion is converted into the rotational motion of the first rotating tube 301 and the second rotating tube 305, providing power support for the subsequent filtration stage.

[0034] Secondly, the feeding process of the filter component 3 is started. The biogas and biogas residue slurry to be treated is pressurized by the booster pump 315 at the feed pipe 314. The slurry is pressed into the recovery cylinder body 312 along the pipe, ready for filtration.

[0035] Next, the crucial filtration stage begins. The raw slurry first enters the raw slurry inlet layer inside the coarse material filter cylinder 306. The coarse material filter cylinder uses a 2-5mm pore size to perform preliminary filtration of the coarse residue in the raw slurry. The filtered material then enters the coarse residue filtration layer between the coarse material filter cylinder 306 and the fine material filter cylinder 307. Subsequently, the material passes through the fine material filter cylinder 307, where fine residue is further filtered using a 0.5-1mm pore size. The staggered distribution of the pores effectively improves the filtration effect.

[0036] Next, the material recycling operation is carried out. The materials that have been filtered through different stages enter the corresponding recycling chambers through the recycling holes 311 at the top of the first recycling chamber 309 and the second recycling chamber 310 during the rotation of the first rotating tube 301 and the second rotating tube 305, respectively, so as to realize the classification and recycling of materials with different particle sizes.

[0037] Finally, the collection device 4 starts working. The bottom of the first recovery chamber 309 and the second recovery chamber 310 are connected to the collection device 4 through pipes. The material in the recovery chamber flows into the collection device along the pipes, completing the joint recovery of biogas and biogas residue, and realizing the effective collection and utilization of resources.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
