Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary treatment of kitchen waste, and specifically relates to a device for treating biogas slurry generated by anaerobic digestion of kitchen waste. Background Art

[0002] Kitchen waste, also known as food waste, refers to the waste generated during food processing, catering services, unit canteens, etc. in people's daily lives. This waste mainly includes unwanted vegetable leaves, leftovers, rice and flour, fish and meat, eggshells, bones, swill, fruit peels, tea dregs, etc. Some of the current biogas slurry treatment systems in the market adopt a traditional method when treating solid waste: that is, the materials are introduced into the fermentation tank, and this process relies on an inclined filter screen and a solid transmission pipeline to achieve. However, this design shows several limitations in practical applications. Firstly, its discharging efficiency is not satisfactory and it is difficult to meet the requirements of high-efficiency treatment. More critically, during the transfer of solid waste into the fermentation tank, due to design deficiencies, there is a high risk of pipeline blockage. Once the pipeline is blocked, it will not only interrupt the normal discharging operation process, but may also have an adverse impact on the stability and efficiency of the entire treatment system, thus failing to meet the growing usage requirements and high-standard operation efficiency requirements. In view of this, there is an urgent need for a more optimized and efficient mechanism for introducing and treating solid waste, aiming to improve the discharging efficiency and significantly reduce the risk of pipeline blockage, ensuring that the biogas slurry treatment system can operate continuously, stably and efficiently to better adapt to diverse application scenarios and strict environmental protection standards. For example, "Utility Model CN218025770U, a device for treating biogas slurry generated by anaerobic digestion of kitchen waste, through the cooperation of a filter screen, a circulating knocking mechanism, a return frame, an elastic guiding mechanism, a driving motor, a solid discharging hole and a feeding hole, can automatically export solid waste through the way of circulating knocking; through the cooperation of a cover plate and an automatic blocking mechanism, it can automatically block the feeding hole after the solid waste enters, without the need for personnel to block it separately; the utility model is convenient to automatically discharge solid waste through the way of circulating knocking, can effectively avoid the phenomenon of blockage during the discharging process, improve the discharging stability, is convenient to automatically squeeze open the feeding hole when the solid waste is introduced, and is convenient to automatically block the feeding hole after the waste is introduced, which is convenient for personnel to operate and does not require personnel to carry out blocking operations separately". For the above problems, there may already be technical means to solve them in the prior art, but this case wants to provide an alternative or replacement technical solution.<<O000006>Content of the Utility Model

[0003] It should be noted that there is an incorrect tag "<O000006>" in the original text which is likely a typo and should be " ". The translation is adjusted accordingly.To achieve the above objectives, the present invention is implemented through the following technical solutions: a food waste anaerobic digestion biogas slurry treatment device, comprising: a main housing, a solid storage housing, and a biogas slurry treatment housing, the solid storage housing being connected to the main housing, a semi-magnetic re-vibration sludge collection structure being installed in the main housing, and a biogas slurry auxiliary collection and exhaust structure being installed in the biogas slurry treatment housing;

[0004] The semi-magnetic re-vibration sludge collection structure includes: a mixed biogas slurry feed port, a protective telescopic rubber layer, a tilting power compartment, a tilting power motor, a transmission carrier plate, a plurality of auxiliary sliding beads on the plate, an electromagnet on the plate, a biogas slurry screen plate, a permanent magnet under the plate, a residue baffle, a baffle extrusion spring, an extrusion spring bracket, and a solid material release door;

[0005] The mixed biogas slurry feed port is mounted on the main housing, the protective telescopic rubber layer is mounted in the main housing, and the protective telescopic rubber layer is connected to the biogas slurry screen plate, the tilting power compartment is mounted on the main housing, the tilting power motor is mounted in the tilting power compartment, the transmission carrier plate is connected to the tilting power motor via a rotating shaft, a plurality of auxiliary sliding beads on the disk are respectively mounted on the transmission carrier plate, the electromagnet on the disk is mounted on the transmission carrier plate, the biogas slurry screen plate is mounted in the main housing via a rotating shaft, the permanent magnet under the plate is mounted on the biogas slurry screen plate, the electromagnet on the disk is movably connected to the permanent magnet under the plate, the residue baffle is mounted in the solid storage housing via a rotating shaft, the baffle extrusion spring is connected to the extrusion spring bracket, and the baffle extrusion spring is connected to the residue baffle, the extrusion spring bracket is mounted in the solid storage housing, and the solid material release door is mounted on the solid storage housing;

[0006] It should be noted that, in the above, the biogas slurry is transported into the main shell through the mixed biogas slurry feed port on the main shell, and the auxiliary sealing cover plate provided on the mixed biogas slurry feed port can seal the entire main shell after the biogas slurry is injected, or the biogas slurry is directly injected into the main shell through the pipe body transfer valve provided on the mixed biogas slurry feed port and connected to the biogas slurry storage pipeline. The injected biogas slurry will first contact the biogas slurry sieve plate, and then drive the tilting power motor in the tilting power bin to operate, thereby driving the transmission carrier disc to rotate. At the same time, the electromagnet on the disc is energized to generate magnetic force. When the permanent magnet under the plate on the biogas slurry sieve plate and the electromagnet on the disc are close to each other, the electromagnet on the disc and the permanent magnet under the plate are connected through The magnetic forces move away from each other, thereby lifting and deflecting the biogas sieve plate, and when the transmission carrier plate continues to rotate until the auxiliary sliding beads on the plate contact the permanent magnet under the plate, the biogas sieve plate will fall. In summary, the biogas sieve plate will be lifted up, dropped and tilted back and forth under the continuous rotation of the transmission carrier plate, and the biogas slurry solid residue on the biogas sieve plate will be tilted and accumulated on one side of the residue baffle. When the accumulated solid residue is so much that the weight exceeds the rebound force of the baffle extrusion spring, the baffle extrusion spring will be compressed toward the extrusion spring bracket and deformed, and the residue baffle will deflect, releasing the blocked solid residue into the solid storage shell, so that the solid residue will be properly collected.

[0007] Preferably, the biogas slurry auxiliary collection and exhaust structure comprises: a pressure relief chamber, a liquid inlet solenoid valve, a gas connection pipe, a biogas slurry release pipe, a biogas slurry release valve, a resistance spring column, an auxiliary sealing plate and a fitting sealing rubber ring;

[0009] It should be noted that, in the above, after the biogas slurry flows into the biogas slurry treatment housing under the control of the liquid inlet solenoid valve, it is properly collected and the other side is closed by the biogas release valve. It can be temporarily stored in the biogas slurry treatment housing. When it needs to be discharged, it can be discharged to the outside or transported to the required place through the biogas release pipe. The stored biogas will produce biogas and other composite gases, which will generate strong internal pressure on the biogas slurry treatment housing. Therefore, when too much gas is generated, the auxiliary sealing plate can be squeezed by the gas, which will compress the resistance spring column in the pressure relief chamber until the gas connection pipe port is exposed to the inner side of the biogas slurry treatment housing. The gas will be discharged from the biogas slurry treatment housing through the gas connection pipe. When the pressure is less than the elastic force of the resistance spring column, the auxiliary sealing plate will return to its original position, and the fitting sealing rubber ring on the auxiliary sealing plate will assist in sealing the pressure relief chamber, and the entire biogas slurry treatment housing will be re-sealed again, thereby completing the decompression of the biogas slurry treatment housing. The spare emergency air release valve provided on the pressure relief chamber can quickly decompress the biogas slurry treatment housing in an emergency, facilitating the handling of emergency situations.

[0010] Preferably, an auxiliary sealing cover is provided on the mixed biogas slurry feed port;

[0011] Preferably, a pipe transfer valve is provided on the mixed biogas slurry feed port;

[0012] Preferably, the pressure relief chamber is provided with a spare emergency air release valve;

[0013] Preferably, a maintenance access is provided on the tilting power bin.

[0014] Beneficial effects

[0015] The utility model provides a device for treating biogas slurry from anaerobic digestion of food waste. Compared with the prior art, the device has the following beneficial effects: the device cleverly integrates a semi-magnetic re-vibration sludge collection structure to achieve efficient treatment of biogas slurry entering the main shell area. During this process, the biogas slurry first passes through a carefully designed biogas sieve plate filtration unit. The unit not only effectively intercepts and removes impurities, but also has unique dynamic characteristics. Through the built-in re-vibration mechanism, the biogas sieve plate can automatically perform periodic tilting, vibration and displacement operations. This innovative design allows solid residues attached to its surface to be easily peeled off and fall into the bottom under the repeated tilting and vibration. Solid storage shell collection area, this process not only ensures the continuous unobstructed flow of the sludge sieve plate filtration unit, avoiding the common clogging problems of traditional filtration devices, but also greatly improves the efficiency and convenience of sludge treatment. In addition, the filter residue after fine filtration by the sludge sieve plate cleverly uses gravity to automatically slide to the solid storage shell collection area, and then triggers the automatic sealing mechanism. This series of smooth operations not only significantly reduces the labor intensity of workers, but also greatly improves the cleanliness and safety of the working environment, and also elevates its applicability to a new level, meeting the needs of efficient and convenient sludge treatment in different scenarios.

The injected biogas slurry will first contact the biogas slurry sieve plate 11, and then drive the tilting power motor 7 in the tilting power bin 6 to operate, thereby driving the transmission carrier disc 8 to rotate. At the same time, the electromagnet 10 on the disc is energized to generate magnetic force.

When it needs to be discharged, it can be discharged to the outside or transported to the required place through the biogas release pipe 20. The stored biogas will produce biogas and other composite gases, which will generate strong internal pressure on the biogas treatment shell 3. Therefore, when too much gas is generated, the gas can squeeze the auxiliary sealing plate 23, which will cause the pressure relief chamber 17 to The resistance spring column 22 inside is compressed until the end of the gas connection pipe 19 is exposed on the inner side of the biogas treatment shell 3, and the gas will be discharged from the biogas treatment shell 3 through the gas connection pipe 19.
