Description

Technical Field

[0001] The utility model relates to the field of kitchen waste treatment, in particular to a kitchen waste biodegradation treatment device. Background Art

[0002] After garbage classification, perishable garbage such as kitchen waste is decentralized and incremental, and the existing terminal processing capacity faces a large gap. The traditional centralized large-scale facility processing chain is long and the social investment burden is heavy. The use of small-scale facilities nearby to dispose of kitchen waste can effectively reduce the source of domestic waste, save social costs, and avoid secondary pollution. It is a new model to solve the problem of kitchen waste treatment. At present, small-scale kitchen waste disposal facilities decompose all organic waste into water and carbon dioxide through biodegradation. However, the oil in the kitchen waste cannot be recycled after decomposition, which easily leads to the waste of oil resources. Utility Model Content

[0014] In one of the embodiments, a first stirring roller is fixed on the incomplete gear, and the first stirring roller is rotatably connected to the partition plate to disperse the degradation products in the upper part of the degradation space.

[0015] In one embodiment, a second stirring roller is provided below the heated plate, one end of the second stirring roller extends out of the box and is connected to the output end of the driving member via a belt drive, and the other end of the second stirring roller is rotatably connected to the partition to disperse the degradable materials in the lower part of the degradation space.

[0031] Before the implementation of garbage classification, kitchen waste was mixed with other domestic waste. Due to the difficulty in sorting, it was impossible to truly realize resource utilization. It was often directly landfilled or incinerated. The characteristics of high water content and low calorific value brought many problems to landfill or incineration. In contrast, the way of microbial degradation of kitchen waste is more environmentally friendly, economical and efficient. The principle of microbial degradation of kitchen waste is to use the metabolic activity of microorganisms to decompose organic matter into inorganic matter. Microbial degradation is divided into two stages: decomposition stage and stabilization stage. In the decomposition stage, microorganisms decompose organic matter into small molecular compounds such as glucose, lactic acid, acetic acid, etc. by secreting enzymes. In the stabilization stage, microorganisms further decompose these small molecular compounds into inorganic substances such as water and carbon dioxide, completing the conversion of organic matter to inorganic matter. In the process of kitchen waste degradation, the grease in liquid waste will not only cause blockage of sewage pipes, but also cause environmental pollution if it is directly discharged. In addition, liquid waste will dilute the biological flora and reduce the effect of biological degradation of solid waste.

[0032] In view of the above problems, the utility model provides a kitchen waste biodegradation treatment device.

[0033] Combine the following Figure 1-Figure 4The utility model describes a kitchen waste biodegradation treatment device.

[0034] like Figure 1 As shown, in one embodiment, a device for biodegradation of kitchen waste includes a box body 100 , a guide plate 200 , a baffle 300 , a heated plate 400 , an aeration assembly 500 and an air assembly 600 .

[0035] The surface of the box body 100 is provided with a feed port 110, and the interior is divided into a dehydration space 130 and a degradation space 140 by a partition 300. A material guide pipe 120 adapted to the feed port 110 is fixedly installed on the box body 100. According to actual needs, a crushing component for crushing kitchen waste can be added in the material guide pipe 120 to make it into small particles for subsequent processing and utilization. One end of the guide plate 200 extends into the degradation space 140 and is tilted relative to the partition 300. When dumping garbage, the opening of the guide pipe 120 is tilted relative to the box body 100, which facilitates the entry of garbage. Then, the liquid contained in the garbage falls into the dehydration space 130 from the water-permeable holes 210 on the guide plate 200 under the action of gravity, and the solid slides into the degradation space 140 along the angle of the guide plate 200, reducing the dilution of the biological flora by liquid garbage and improving the effect of microorganisms on solid garbage degradation; this kind of microbial filler is a room-temperature strain with an operating temperature of about 35°C to 40°C. When the ambient temperature is above 20°C, the temperature in the cavity can be maintained basically by the heat energy generated by the microorganisms themselves; the heating plate 400 is arranged in the degradation space 140, and a metal material with good thermal conductivity is selected, and a bend 410 is provided inside, referring to Figure 2 The aeration assembly 500 is fixed in the dehydration space 130, and includes an aeration tube 510 and a first connector 520. The aeration tube 510 has nanopores 511 arranged in an array. The aeration tube 510 is rotatably connected to one end of the first connector 520. The end of the first connector 520 away from the aeration tube 510 is rotatably mounted on the partition 300 and fixedly connected to the heated plate 400. The first connector 520 is connected to the bend 410. Figure 3 The air assembly 600 is arranged outside the box 100, and includes an air pump 610, an air pipe 620 and a second connector 630. One end of the air pipe 620 located outside the box 100 is fixedly connected to the air pump 610, and the other end of the air pipe 620 is rotatably connected to the second connector 630. The second connector 630 is rotatably mounted on the side wall of the box 100 and fixedly connected to the heated plate 400. The second connector 630 is connected to the bend 410. Figure 4 .

[0036] When the kitchen waste biodegradation treatment device in this embodiment is working, the kitchen waste enters the box body 100 through the feed inlet 110 and first contacts the guide plate 200 for solid-liquid separation, and then mixes with the microbial filler to undergo a degradation reaction. The heat generated by the reaction is transferred to the heating plate 400. The air pump 610 heats the external normal temperature air when passing it into the bend 410 in the heating plate 400, and then sprays it out from the nanopores 511 on the aeration pipe 510 to form tiny bubbles with heat. On the one hand, the grease particles in the dehydration space 130 are dissolved to improve the recovery efficiency; on the other hand, the tiny bubbles can absorb the oil and other suspended matter in the water, causing them to float to the surface, further improving the removal efficiency.

[0037] Since the grease particles need to be melted at a certain temperature, in order to increase the heating capacity of the heated plate 400, a driving member 700 is fixedly installed on the box body 100, and the driving member 700 includes a motor 710, an incomplete gear 720 and a flat gear 730, and the incomplete gear 720 and the flat gear 730 are meshed and connected. The output end of the motor 710 is located at one end inside the box body 100 and is fixed to the incomplete gear 720, and the flat gear 730 is fixedly installed on the second connector 630. However, the microbial filler is relatively loose and can be easily stuck in the grooves of the incomplete gear 720 and the flat gear 730. Therefore, a sealed box 740 is fixedly installed on the inner wall of the box body 100, and the incomplete gear 720 and the flat gear 730 are located in the sealed box 740. Figure 4 .

[0038] The microbial filler filled in the box 100 is relatively soft, and the heating plate 400 is provided with slots 420 equidistantly on both sides along the length direction, which can disperse the bacteria and increase the heating surface of the heating plate 400 .

[0039] Driven by the motor 710, the incomplete gear 720 intermittently drives the heated plate 400 to rotate in the microbial filler through the flat gear 730. On the one hand, it can fully mix the kitchen waste and the filler, and on the other hand, it improves the heat reception of the heated plate 400, so that the internal air heats up quickly, increases the bubble temperature, and accelerates the recovery efficiency.

[0040] A first stirring roller 800 is fixed to the incomplete gear 720, and the first stirring roller 800 is rotatably connected to the partition 300, and is used to disperse the degradation products in the upper part of the degradation space 140. A second stirring roller 900 is arranged below the heated plate 400, and one end of the second stirring roller 900 extends out of the box 100 and is connected to the output end of the motor 710 through a belt transmission, and the other end of the second stirring roller 800 is rotatably connected to the partition 300, and is used to disperse the degradation products in the lower part of the degradation space 140.

[0041] Specifically, when the motor 710 drives the incomplete gear 720 to rotate, the first stirring roller 800 follows the rotation and transmits the rotational force to the second stirring roller 900 through the belt. The first stirring roller 800 and the second stirring roller 900 have the same structure and are respectively located on both sides of the heated plate 400, and the space between the first stirring roller 800 and the second stirring roller 900 is sufficient to accommodate the distance required for the heated plate 400 to flip.

[0042] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
