detailed description

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

Example 1

In the embodiment 1 shown in Fig. 1, Fig. 2, Fig. 3, a kind of leaf processing device comprises incinerator 1, feeding device 2, smoke cleaning device 7 and preheating device 3; Incinerator comprises furnace body 1b, Furnace head 1a and furnace tail 1c, the incinerator is arranged obliquely, and the height of the burner head will be higher than the furnace tail. There is an incineration chamber 1d inside the body of furnace, as shown in Fig. 2, a transmission spindle 10 driven by a main motor 9 is provided in the incineration chamber, and a plurality of bulk bodies 11 for moving materials are arranged on the transmission shaft. It is a hollow tubular structure, arranged along the radial direction of the transmission shaft, and also includes an air pump that can blow air into the inner cavity of the main shaft, and the central through hole of the bulk body communicates with the inner cavity of the main shaft. The furnace head is provided with a feed inlet and a gas outlet 101, and the furnace tail is provided with a feed outlet and an air inlet 102. The gas outlet and the inlet are located at the top of the incinerator, and the feed inlet and the outlet are located at the bottom of the incinerator. The air inlet is connected with an air compressor to ensure sufficient air intake. It also includes a drive motor for the furnace body. The furnace body is connected to the furnace head and the furnace tail in rotation. Support wheels 104 are respectively provided at the two ends of the furnace body to support and position the furnace body. A coaxial ring gear 103 is fixed on the furnace body. The furnace body is driven by a motor.

The feeding device includes a feeding cylinder 2a extending from the feeding port of the furnace head into the incineration chamber. The end of the feeding cylinder is provided with a coaxial compression part 2b. The diameter of the compression part gradually decreases from the feeding cylinder. The compression part and the feeding cylinder There is a smooth transition between them, the preheating barrel 2c communicates with the outlet end of the compression part, the preheating barrel is located in the incinerator, and is located at the end of the incinerator away from the air inlet. A feeding auger 21 is arranged in the feeding barrel, and the feeding auger is helical, and its pitch gradually decreases from the feeding barrel to the direction of the compression part, and the edge of the feeding auger is provided with a continuous cutting edge. The feeding auger is provided with an inner through hole 21a on the inner side close to the rotating shaft. When the feeding auger is running, the material undergoes centrifugal action, and the moisture in the material gathers on the inner side of the feeding auger near the rotating shaft, thereby reducing the moisture content in the material. The compression part is provided with rotatable meat grinder 12 close to its outlet end, and the rotation axis of meat grinder is coaxial with feeding auger, and meat grinder can adopt cross blade, is used for leaf chopping.

The leaves are first cut into large pieces by the feeding auger in the feeding cylinder, and then because the pitch of the feeding auger gradually shrinks, the material is gradually cut into small pieces and pushed to the compression part at the same time. After the materials reach the compression part, they start to squeeze each other tightly and approach the exit end of the compression part in this state. The meat grinder at the exit end rotates at high speed to continue cutting the small pieces of material into smaller particles, so as to enter the incineration chamber. Air or other combustion-supporting gases enter the incinerator from the air inlet. The leaf material enters the incinerator in a squeezed state, so the air at the feed port cannot circulate, and the material is prevented from burning in the feeding cylinder and the compression part, so first of all, it is ensured that the material on the outside will not be burned in large quantities first, and avoiding external factors. The material is incinerated and carbonized first, which leads to the problem that the material squeezed in the middle is difficult to ignite and cannot be fully burned. After the material enters the bulk material area, it begins to be continuously stirred and dispersed. At this time, the dispersed material will fully contact with the air and can be burned better.

During the incineration process of the material, it is inevitable that some unburned parts will be left, and the formed plant ash powder will also cover these unburned parts, making it difficult to continue burning. At this time, since the bulk material is constantly stirring, the newly fed material and the unburned material including plant ash powder will be driven up together, and then let it fall down, so as to repeatedly disperse, and then use the newly fed material to disperse. Combustion and fire, to achieve re-burning. The stirring function of the bulk material is realized by the main motor driving the drive shaft to rotate. In application, auxiliary devices such as reducers can also be added to the main motor according to actual needs, so that the speed of the drive shaft can be at a more reasonable level. In terms of range, the drive shaft can be supported and positioned by shaft brackets, bearings or other commonly used structures that cooperate with the shaft, so that it can work stably in the incinerator. In addition, the furnace body rotates under the drive of the furnace body drive motor, which makes the materials roll continuously in the furnace body to avoid the accumulation of materials at the bottom of the incineration chamber. At the same time, the air is pumped into the inner cavity of the main shaft, and the air or supporting gas can enter the incineration chamber from the central through hole of the bulk material body, which improves the tumbling effect of the material and ensures the full combustion of the material.

The preheating device includes a preheating hopper 3a and a spiral flue 3d. The preheating hopper is in the shape of a cone with a large top and a small bottom. The spiral flue surrounds the outer wall of the preheating hopper. The bottom of the spiral flue is the air inlet 3c. Above is the gas outlet 3b, the gas inlet of the spiral flue communicates with the gas outlet of the incinerator, and the blanking end 301 of the preheating hopper communicates with the feeding end 2d of the feeding cylinder. Due to the high water content of the leaves, the temperature of the hot flue gas generated in the incinerator is high, which can heat the material in the preheating hopper, thereby increasing the temperature of the material and reducing its moisture content. In addition, since the feeding cylinder also extends into the In the incinerator, so the heat in the incinerator also heats the material in the feeding barrel at the same time. After preheating, the material becomes easy to cut and ignite, thus reducing energy consumption.

The smoke cleaning device includes a smoke exhaust outer channel 7a and a sink 703. The smoke exhaust outer channel is connected to the air outlet. A plurality of shower heads 701 are arranged on the upper side of the smoke exhaust outer channel. The water spraying direction is from top to bottom. The smoke exhaust outer channel and the The sink is connected. In addition, it also includes a smoke exhaust pipeline 8, and the smoke exhaust final channel 7b is formed between the inner wall of the smoke exhaust pipeline and the water surface of the sink, and a plurality of sprayers 702 are arranged in the smoke exhaust final channel. The entrance of the channel is connected with the outlet of the outer smoke exhaust channel, and the outlet of the final smoke exhaust channel is connected with the hot and humid gas pipe 8a. There is a settling chamber 5 between the gas outlet end of the spiral flue and the smoke cleaning device, the settling chamber and the gas outlet end of the spiral flue are connected by a smoke outlet pipe 4, and the settling chamber and the smoke cleaning device are connected by a smoke pipe 6 connections, the caliber of the smoke cleaning device is 3 to 10 times the caliber of the smoke outlet pipe. The connecting part of the smoke outlet pipe and the settling chamber is located at the upper part of the mouth of one end of the settling chamber, the connecting part of the smoke passing pipe and the settling chamber is located at the upper part of the mouth of the other end of the settling chamber, and the lower part of the settling chamber is provided with a discharge door 5a.

The hot flue gas produced after combustion contains a large amount of solid particles. The hot flue gas enters the settling chamber after passing through the outlet end of the spiral flue. The air flow leaves the settling chamber with relatively lighter solid particles and enters the smoke purification device. At this time, the hot flue gas enters the outer exhaust channel. The shower head in the outer exhaust channel can be sprayed with water, forming a section of flue gas channel similar to the rainfall part in the outer exhaust channel, the temperature of the hot flue gas is appropriately lowered, and the solid and large particles in it are taken away by the "rainwater" in large quantities, and fall with it. The water enters the sink together, so as to realize the purification of flue gas. After that, the flue gas will pass through the final smoke exhaust channel, and the sprayer will spray water mist, forming a large area of purified water mist in the final smoke exhaust channel. Realize the purification of flue gas.

Example 2

The basic structure and implementation of this embodiment are the same as those of Embodiment 1. The difference is that, as shown in Figure 4, it also includes a dirt-cleaning motor. Transmission inner shaft 17 stretches among the main shaft inner cavity. One end of the transmission inner shaft can be driven to rotate by the output shaft of the cleaning motor, and the other end is connected with the bearing of the inner shaft, and multiple cleaning devices are arranged on the transmission main shaft. The dirt removal device comprises a dirt ball 18, a limit ball 19, a ball receiving spring 16, a slide bar 15, a slide hole arranged on the drive shaft wall, the slide bar and the slide hole are slidably matched, and the dirt ball and the limit ball are respectively connected with the The two ends of the slide rod are connected, and the ball receiving spring is set on the slide rod and is between the limit ball and the inner wall of the transmission spindle. The push plate 13 of the limit ball, each limit ball corresponds to a push plate. The cleaning device also includes an extended protection base 14, the extended protection base is connected to the inner wall of the rotor main shaft, the slide bar passes through the extension protection base, and the two ends of the ball receiving spring respectively press the limit ball and the extension protection base. The dirt ball and the slide bar of the same dirt cleaning device, the vertical connection line between the ball center of the dirt ball and the axis of the rotor main shaft, forms an angle of 20 to 45 degrees with the slide bar therein.

After the incineration, a large amount of ash and mud scaling will be left in the incineration chamber and the furnace wall. Due to the large size of the incinerator, it is difficult to disassemble and clean. After a long time, it is easy to cause too many hard blocks on the furnace wall, which is harmful to the environment. Subsequent use may cause adverse effects. At this time, the scaling motor can be started to drive the transmission inner shaft to rotate rapidly, and the transmission inner shaft drives the push plate to rotate at a high speed together, the push plate is pushed, the impact limit part moves outward, the ball receiving spring is compressed, and the scale ball leaves the transmission shaft , start to knock on the inner wall of the drying main cylinder, and at the same time, let the relatively slow-speed transmission spindle work and rotate, driving the slide bar to continuously change its position and orientation, so that each dirt ball can hit the inner wall of the drying main cylinder In many places, the fouling in the incinerator is cleaned by direct knocking and indirect vibration. In addition, the air pump can be turned on at the same time to make the compressed air blow to the inner wall through the bulk material, which can be assisted by knocking vibration to improve the cleaning effect.
