Description

Technical Field

[0001] The present invention relates to an in-vehicle garbage pre-fermentation treatment device and a garbage treatment vehicle, belonging to the technical field of environmental sanitation equipment. Background Art

[0002] In China, the generation points of township kitchen waste are scattered, and the garbage stock at each generation point is small. It is very difficult to effectively collect and transport the township kitchen waste. The treatment of kitchen waste is difficult and the treatment efficiency is low. A large amount of kitchen waste is usually collected, transported, landfilled or incinerated together with domestic waste, resulting in a large amount of landfill leachate and low incineration calorific value, which greatly affects the effect of garbage treatment.

[0003] Generally, the landfill treatment, incineration treatment and crushing and discharging treatment of kitchen waste are not effective treatment methods, which are likely to cause adverse effects on the environment. Since the commonly used garbage treatment vehicle can only collect and transport garbage and cannot effectively treat or pre-treat kitchen waste; due to the high solid content of the collected kitchen waste, solid-liquid separation / stratification or crust formation is likely to occur during the fermentation process, resulting in extremely uneven distribution of substrates, anaerobic microorganisms and nutrients. Therefore, the anaerobic biogas production cycle of ordinary kitchen waste is long and the efficiency is low, which makes the problem of village and town garbage pollution unable to be effectively solved. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides an in-vehicle garbage pre-fermentation treatment device that can timely and efficiently ferment the collected kitchen waste. The present invention also provides a garbage treatment vehicle with the in-vehicle garbage pre-fermentation treatment device.

[0005] The technical solution adopted by the present invention to solve the above technical problems is as follows:

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] By setting up the main body of the fermentation treatment device, it is possible to timely and effectively ferment the pre-collected kitchen waste.

Detailed implementation manners

[0026] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments.

[0027] As Figures 1-6 shown, a vehicle-mounted garbage pre-fermentation treatment device includes the main body 1 of the garbage disposal vehicle. A fermentation treatment device main body 2 is provided on the garbage disposal vehicle main body 1. The fermentation treatment device main body 2 includes an anaerobic fermentation tank 3 fixedly installed on the garbage disposal vehicle main body 1. A feed pipe opening 4 is provided on one side of the anaerobic fermentation tank 3. A plurality of first motors 5 are fixedly installed on the other side of the anaerobic fermentation tank 3. Two stirring rollers 6 connected to the first motors 5 are movably installed inside the anaerobic fermentation tank 3. A storage cover 7 is fixedly installed on the top of the anaerobic fermentation tank 3. A discharge port 8 is opened on the anaerobic fermentation tank 3, and a sealing plate 9 is movably installed on the discharge port 8. Through the setting of the fermentation treatment device main body 2, the pre-collected food waste can be fermented in a timely manner. The food waste is collected and placed in the anaerobic fermentation tank 3. After exhausting oxygen, a plurality of first motors 5 are started to drive the stirring rollers 6 to stir the food waste inside the anaerobic fermentation tank 3, so that the food waste ferments inside the anaerobic fermentation tank 3 and generates biogas, and the biogas floats to the storage cover 7 for storage for collection and utilization, which is beneficial to improving the environmental pollution problem caused by food waste and facilitating the resource utilization of garbage.

[0028] In this embodiment, as Figures 1-6 shown, a fixing frame 10 is fixedly installed on the feed pipe opening 4. Two second motors 11 are fixedly installed on one side of the fixing frame 10. Two crushing rollers 12 connected to the second motors 11 are movably installed inside the fixing frame 10; the setting of the fixing frame 10, the second motors 11 and the crushing rollers 12 can crush the input food waste so that it enters the anaerobic fermentation tank 3 for fermentation after being crushed.

[0029] Two fixing blocks 13 are symmetrically arranged on the surface of the fixing frame 10. Two electric telescopic rods 14 are symmetrically installed on the fixing blocks 13. Two baffles 15 connected to the electric telescopic rods 14 are arranged on the fixing frame 10. The arrangement of the fixing blocks 13, the electric telescopic rods 14 and the baffles 15 can, after the garbage collection is completed, start the contraction of multiple electric telescopic rods 14 at the same time to drive the movement of the baffles 15 to seal the feeding port of the fixing frame 10.

[0030] A valve 16 is fixedly installed at the top of the storage cover 7. A delivery pipe 17 is fixedly installed on the valve 16. Two support frames 18 are symmetrically and fixedly installed on the delivery pipe 17. A screw rod 19 is movably installed inside the support frame 18. A moving block 20 is installed on the screw rod 19. A clamping plate 21 is fixedly installed on the moving block 20. A rotating rod 22 connected to the screw rod 19 is arranged on one side of the support frame 18. When discharging biogas, to avoid biogas leakage, after docking the external pipeline with the delivery pipe 17, rotate the rotating rod 22 to drive the screw rod 19 to rotate. The screw rod 19 drives the moving block 20 to move to push the clamping plate 21, so that both clamping plates 21 are in contact with the external pipeline for clamping and fixing. Then open the valve 16 to discharge and transport the biogas in the storage cover 7.

[0031] In this embodiment, as Figures 1-6 shown, sealing gaskets 23 are fixedly installed on the sides of the two clamping plates 21 close to each other. A plurality of push rods 24 are evenly and fixedly installed on the surface of the rotating rod 22. After the sealing gaskets 23 are arranged on the clamping plates 21, it can not only improve the firmness of the clamping of the external pipeline by the clamping plates 21, but also play a sealing role at the connection to avoid biogas leakage. The arrangement of the push rods 24 facilitates the pushing and rotation of the rotating rod 22.

[0032] On both sides of the anaerobic fermentation tank 3, an acidic material loading tank 25 and an alkaline material loading tank 26 are fixedly installed respectively. At the bottom of both the acidic material loading tank 25 and the alkaline material loading tank 26, a delivery pump 27 is fixedly installed. A discharge pipe 28 extending into the interior of the anaerobic fermentation tank 3 is fixedly installed on the delivery pump 27. Windows 29 are fixedly installed on both the acidic material loading tank 25 and the alkaline material loading tank 26. A plurality of movable doors 30 are movably installed on the tops of both the acidic material loading tank 25 and the alkaline material loading tank 26. The settings of the acidic material loading tank 25, the alkaline material loading tank 26, the delivery pump 27 and the discharge pipe 28 can adjust the internal pH value of the anaerobic fermentation tank 3. When the acidic value in the anaerobic fermentation tank 3 is higher than the predetermined value, the delivery pump 27 below the alkaline material loading tank 26 is started to input the alkaline substances inside it into the anaerobic fermentation tank 3 for neutralization. When the alkaline value is higher than the predetermined value, the delivery pump 27 below the acidic material loading tank 25 is started to input the acidic substances inside it into the anaerobic fermentation tank 3 for neutralization. By relying on the window 29, the remaining amount of the materials in the acidic material loading tank 25 or the alkaline material loading tank 26 can be checked, and the materials can be replenished by opening the movable door 30.

[0033] In this embodiment, as Figures 1-6 shown, a pH detector 31 is fixedly installed on the surface of the anaerobic fermentation tank 3, and one end of the pH detector 31 extends into the interior of the anaerobic fermentation tank 3. The number of the discharge ports 8 and the sealing plates 9 is set to two, and they are symmetrically arranged on both sides of the bottom of the anaerobic fermentation tank 3. The setting of the pH detector 31 can detect the pH value inside the anaerobic fermentation tank 3 in real time. By setting the discharge ports 8 and the sealing plates 9 to two and symmetrically arranging them on the anaerobic fermentation tank 3, it is more convenient to clean the fermented garbage inside the anaerobic fermentation tank 3.

A first heat exchanger 32 is fixedly installed on the garbage treatment vehicle body 1. A plurality of conduits 33 are fixedly installed on one side of the first heat exchanger 32. One side of the conduits 33 is connected to a second heat exchanger 34 arranged inside the anaerobic fermentation tank 3. By setting the first heat exchanger 32, the conduits 33 on the garbage treatment vehicle body 1 and the second heat exchanger 34 inside the anaerobic fermentation tank 3, the garbage treatment vehicle body 1 can directly transfer heat to the interior of the anaerobic fermentation tank 3. The first heat exchanger 32 absorbs the heat generated by the garbage treatment vehicle body 1 and transfers it to the second heat exchanger 34 through the conduits 33, so that the second heat exchanger 34 heats the interior of the anaerobic fermentation tank 3, and cooperates with stirring to raise the temperature inside the anaerobic fermentation tank 3 to the temperature required for fermentation.

[0035] As Figures 1-6 shown, the working process of the on-vehicle garbage pre-fermentation treatment device provided in this embodiment is as follows:

[0036] Put the kitchen waste into the anaerobic fermentation tank 3 from the feed pipe orifice 4. The waste first enters into the fixed frame 10. Start the two second motors 11 to drive the crushing rollers 12 to rotate, and pre-crush the input kitchen waste so that it can ferment better in the anaerobic fermentation tank 3 after crushing. Start multiple first motors 5 to drive the stirring rollers 6 to stir the kitchen waste inside the anaerobic fermentation tank 3, so that the kitchen waste ferments inside the anaerobic fermentation tank 3 and generates biogas. The generated biogas floats up to the storage cover 7 for storage, separating the biogas from the waste.
