Description

Technical Field

[0001] The utility model relates to the technical field of delivery components, in particular to a fuel delivery component. Background Art

[0002] A rotary kiln is a type of equipment commonly used in the cement production process. It converts raw materials into cement clinker by pyrolyzing and calcining them at high temperatures. Pulverized coal is one of the most common fuels for rotary kilns. Pulverized coal has high combustion efficiency and calorific value and is relatively easy to obtain. In a rotary kiln, pulverized coal is supplied with oxygen at high temperatures to burn, releasing enough heat energy to heat and calcine the raw materials. Natural gas is also one of the common fuels for rotary kilns, and petroleum coke is sometimes used.

[0003] In order to solve the problem of domestic waste disposal, RDF alternative fuel will be used. RDF is obtained by treating and processing domestic waste or waste. The combustible part extracted from domestic waste or other waste is used as a form of energy to replace traditional fossil fuels after treatment and processing. It effectively utilizes renewable resources and realizes the recycling of waste. Compared with fossil fuels, the combustion process of RDF releases lower levels of greenhouse gases such as carbon dioxide, which helps to mitigate climate change and improve air quality.

[0004] However, when combustible domestic waste is used as fuel, there is a moisture problem inside the waste. Wet waste contains a high moisture content, which will cause a large amount of heat to be used to evaporate the moisture during combustion and cannot be effectively converted into thermal energy. Therefore, directly using wet waste as fuel will reduce the combustion efficiency of the rotary kiln, and more fuel is required to achieve the same energy output. For this reason, we propose a fuel delivery component to solve the existing problem. Utility Model Content

[0005] The purpose of the utility model is to propose a fuel delivery component in view of the problems existing in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fuel conveying assembly, comprising a cover body, a rotary kiln, a bottom plate, a conveyor belt and a hydraulic rod, wherein a rotary kiln is arranged on the upper end of the bottom plate, a cover body is sleeved on the outer side of the rotary kiln, rollers equidistantly distributed are rotatably installed inside the upper end of the cover body, a conveyor belt is rotatably sleeved on the outer wall of the roller, a motor is arranged on the outer wall of the cover, and hydraulic rods are arranged on both the front and rear sides of the upper end of the bottom plate.

[0007] When a fuel conveying component in the present scheme is used, combustible garbage is dumped into the feed port, and falls to the upper side of the conveyor belt through the feed port. The motor drives the roller to rotate, which drives the conveyor belt to rotate to convey the combustible garbage. The cover intercepts the residual heat of the rotary kiln, and the hot air flows upward, passes through the opening of the conveyor belt, and contacts the combustible garbage. The combustible garbage is thermally treated by the hot air flow, and the internal moisture is evaporated. In the process of conveying the combustible garbage, drying treatment is achieved.

[0008] Preferably, the output end of the motor is connected to one end of the roller. The motor drives the roller to rotate, and the conveyor belt is driven to rotate through friction with the conveyor belt.

[0009] Preferably, the conveyor belt is provided with through holes which are evenly spaced, so that the hot air flow directly flows upward through the through holes and enters the lower end of the combustible garbage.

[0010] Preferably, the outer wall of the conveyor belt is provided with a filter screen, which intercepts small-sized combustible garbage to prevent the small-sized combustible garbage from clogging the through holes.

[0011] Preferably, a discharge port is provided inside one end of the cover body, a guide plate is provided on one side of the lower end of the conveyor belt, and limit plates are provided on both sides of the upper end and the rear end of the guide plate. The guide plate is inclined, and one end passes through the discharge port. The guide plate guides the combustible garbage and conveys it to the receiving device through the discharge port.

[0012] Preferably, the inner wall of the upper end of the cover body is provided with symmetrically distributed baffles, the baffles are located at the front and rear sides of the upper end of the conveyor belt, and a feed port is provided inside one side of the upper end of the cover body, the feed port is located on the upper side of the conveyor belt. The baffles intercept the front and rear ends of the conveyor belt, and the feed port receives and transfers the dumped combustible garbage.

[0013] Preferably, top plates are provided on both the front and rear sides of the upper end of the cover body, the telescopic end of the upper end of the hydraulic rod is connected to the lower end of the top plate, both ends of the cover body are provided with travel ports, both ends of the rotary kiln pass through the travel ports, and the inside of the cover body is hollow. The hydraulic rod drives the top plate to move longitudinally, driving the cover body to move, ensuring the passage of the cover body through the travel port, and at the same time ensuring the rotation of the rotary kiln.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model has a cover body sleeved on the outside of the rotary kiln, so that the waste heat of the rotary kiln is intercepted and suppressed for a short time, and a conveyor belt is arranged inside the upper end of the cover body. The waste heat in the fuel process of the rotary kiln can be absorbed and transferred to the combustible garbage on the upper end of the conveyor belt. The garbage in the transportation process can be dried by the transfer of waste heat, reducing the moisture content in the garbage and improving its combustibility.

[0016] 2. By absorbing the waste heat emitted by the rotary kiln, the heat energy is transferred to the garbage, and the preheating is effectively utilized, reducing the waste of rotary kiln preheating energy and realizing energy recovery. BRIEF DESCRIPTION OF THE DRAWINGS
