Description

Technical Field

[0001] This utility model relates to the field of kitchen waste treatment equipment, specifically to a drum-type biological dryer for treating kitchen waste. Background Technology

[0002] With my country's development and the gradual improvement of people's living standards, the amount of kitchen waste generated is also increasing rapidly, leading to a rapid increase in the annual amount of kitchen waste processed. Kitchen waste in my country has a complex composition, characterized by high organic matter content (over 80%), high moisture content (80%–90%), high oil content, high salt content, low calorific value, and high perishability. If not treated promptly, its high moisture and organic matter content can lead to the rapid growth of pathogenic microorganisms such as Salmonella, the breeding of flies and mosquitoes, and the potential production of harmful substances such as dioxins, endangering human health, water bodies, soil, and the living environment. Aerobic biological drying is one of the optimal choices for treating kitchen waste.

[0003] Currently, the biological drying of kitchen waste mostly uses horizontal reactors. Because the reactor chamber is static, the kitchen waste is agitated using a stirring shaft and aerated from the bottom. This often results in uneven mixing of the waste, uneven airflow distribution within the chamber, and poor aeration. Ultimately, this leads to a low rate and poor efficiency of aerobic biological drying and fermentation.

[0004] Therefore, this utility model provides a drum biological dryer for processing kitchen waste. The drum biological dryer is used to process kitchen waste. Lifting plates are arranged on the inner wall of the drum. The rotation of the drum drives the lifting plates to move, which in turn drives the kitchen waste inside the drum to move, thereby enhancing the mixing effect of the kitchen waste. An aeration mechanism is arranged inside the drum to aerate the material inside the drum, thereby improving the processing effect of kitchen waste. Utility Model Content

[0005] The purpose of this utility model is to provide a drum-type biological dryer for processing kitchen waste, thereby improving the efficiency of kitchen waste treatment. To achieve the above objective, the technical solution adopted by this utility model is as follows:

[0006] A rotary drum biological dryer for processing kitchen waste is disclosed. The drum body is welded from steel plates and rotates under the drive of a motor. The outer ring of the drum body features a right-side support roller structure, a gear-driven roller structure, and a left-side support roller structure. Lifting plates are arranged on the inner wall. The left and right end caps are not welded to the drum body but are connected to the frame and do not rotate with the drum body. The left and right end caps have annular structures into which the drum wall is inserted. The left end cap has a feed inlet and an aeration shaft hole, through which the left air intake aeration shaft of the aeration mechanism is supported. The feed inlet is used for feeding. The right end cap has a discharge outlet, a right-sealed aeration shaft hole, and a right-end-cap vent. The discharge outlet is used for discharging material, the right-sealed aeration shaft hole supports the right-sealed aeration shaft, and the right-end-cap vent is used for gas discharge.

[0007] Furthermore, the aeration mechanism consists of a left-inlet aeration shaft, four aeration hole shafts, and a right-sealed aeration shaft. The left-inlet aeration shaft and the right-sealed aeration shaft are respectively embedded in the aeration shaft holes on the left and right end caps of the drum and connected to the left and right end caps, and do not rotate with the drum body; the right-sealed aeration shaft is only connected to the right end cap and serves as a support; the left-inlet aeration shaft is connected to the aeration fan, and the aeration fan supplies oxygen and removes water from the material bin.

[0008] Furthermore, the uppermost aeration shaft among the four aeration shafts is positioned close to the center of the drum and far from the drum wall, so as to ensure that the aeration shaft can be covered when the drum is filled with more than 70% material, thus avoiding ineffective aeration; the remaining left and right aeration shafts and the lowermost aeration shaft are all positioned close to the drum wall.

[0009] Furthermore, each of the four aeration hole shafts has four rows of evenly distributed aeration holes arranged vertically and horizontally. The diameter of the aeration holes is 3mm. The adjacent rows of aeration holes are arranged at 90°, and the spacing between each aeration hole in each row is equal.

[0010] Furthermore, approximately 10 copying plates are arranged each week, with staggered arrangement between adjacent two-week periods, for a total of approximately 7 weeks from left to right.

[0011] The mechanism of this utility model is as follows:

[0012] A drum-type biological dryer is used to process kitchen waste. Lifting plates are arranged on the inner wall of the drum. The rotation of the drum drives the lifting plates to move, which in turn drives the kitchen waste inside the drum to move, thereby enhancing the mixing effect of the kitchen waste. An aeration mechanism is arranged inside the drum to aerate the material inside the drum, thereby improving the processing efficiency of kitchen waste.

[0013] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0014] 1. This utility model uses a drum mixer, which can make kitchen waste more evenly mixed;

[0015] 2. The aeration pipe of this utility model is stationary and does not rotate with the cylinder, making it easy to connect to the aeration blower;

[0016] 3. The present invention has dense aeration holes and aeration pipes are arranged in the upper, middle and lower layers of the material for aeration, resulting in better uniform aeration of the material. Attached Figure Description
