Description

Technical Field

[0001] The invention belongs to the technical field of heat source energy supply equipment, in particular to a rice bran hot air furnace for bio-granules. Background Art

[0002] The hot air furnace is a thermal power machine that began to be widely used in my country in the late 1970s. It has become a replacement product for electric heat sources and traditional steam power heat sources in many industries. After the grain is harvested, its stems, leaves and husks are also good combustion sources.

[0003] In order to improve the combustion rate and utilization rate of rice bran, traditional rice bran hot air furnaces for bio-pellets mostly need to crush the rice bran before placing it in the incinerator. When the source of the rice bran is different, the degree of crushing also needs to be different. Obviously, traditional rice bran hot air furnaces do not have this function, and it is difficult to have a good control of the amount of materials in the traditional rice bran hot air furnace during the feeding process, which will also affect its utilization rate. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a rice bran hot air furnace for bio-granules, which solves the problem that many existing traditional rice bran hot air furnaces for bio-granules need to crush the rice bran before placing it in an incinerator. When the source of the rice bran is different, the degree of crushing also needs to be different. Obviously, traditional rice bran hot air furnaces do not have this function, and it is difficult to have a good control of the amount of material in the traditional rice bran hot air furnace during the feeding process, which will also affect its utilization rate.

[0006] (II) Technical solution

[0007] To achieve the above purpose, the present invention is implemented through the following technical solutions: a rice bran hot air furnace for bio-granules, comprising a box body, two first motors, a pre-installed box, a second motor, a refinement box, a blower, an incinerator, an air outlet pipe and a screen filter plate, the two first motors are slidably connected to the outer wall of the box body, two crushing rollers are arranged inside the refinement box, both ends of the two crushing rollers are fixedly connected to a transmission shaft, the outer surface of the transmission shaft is rotatably sleeved with an adjustment cylinder, the side wall of the adjustment cylinder is fixedly connected to an adjustment member, and the end of the adjustment member away from the adjustment cylinder is connected to the inner side of the box body. The wall is fixedly connected, the bottom of the refinement box is connected with a leakage plate, two guide plates are arranged below the refinement box, the two guide plates are fixedly connected to the inner wall of the box body, two fixed limit plates are arranged below the guide plate, a feeding tray is arranged between the two fixed limit plates, the outer wall of the feeding tray is fitted with the side wall on the opposite side of the two fixed limit plates, the driving end of the second motor extends through the side wall of the box body to the interior and is fixedly connected to the center position of the feeding tray, a plurality of loading troughs are opened inside the feeding tray, and the plurality of loading troughs are distributed in a ring array.

[0008] Preferably, crushing blades are fixed on the outer surfaces of the two crushing rollers, and the crushing blades are divided into two sections with the same length and opposite rotation directions, so as to increase the crushing force. At the same time, as the crushing blades rotate during crushing, the material can be transferred to the middle position of the refinement box.

[0009] Preferably, a plurality of the loading troughs are provided with adjusting parts inside, and the output ends of the plurality of the adjusting parts are fixedly connected with adjusting plates, and the adjusting plates are slidably connected to the inner wall of the loading trough to adjust the space inside the loading trough for loading materials.

[0010] Preferably, the adjusting member and the positioning member are both electric push rods, which are easy to drive and have high stability.

[0011] Preferably, the two fixed limiting plates are both arc-shaped, so as to facilitate the smooth rotation of the feeding tray.

[0012] Preferably, the two crushing rollers are located on the same horizontal line, so as to improve the stability of the two crushing rollers when they move during the crushing process.

[0013] Preferably, the number of the loading troughs is 3, which can cooperate with the periodic intermittent drive of the second motor to achieve quantitative loading and feeding.

[0014] Working principle: When in use, place the material to be incinerated inside the pre-packed box, start the two first motors, so that the two crushing rollers rotate in opposite directions, and the material is crushed under the crushing action of the crushing leaves. Since the crushing leaves are divided into two sections with the same length and opposite rotation directions, the crushing force is increased. At the same time, as the crushing leaves rotate, the material can be transferred to the middle position of the refinement box. When the crushing force needs to be adjusted according to the type of crushed material, start the adjustment member, which changes the distance between the two crushing rollers through the adjustment cylinder, and then different crushing forces can be obtained, so that the equipment can use different combustion sources as raw materials to provide heat sources, and the combustion of the raw materials The utilization rate of incineration is well guaranteed. The crushed materials with qualified sizes pass through the leakage plate and fall into the charging trough under the guidance of the guide plate. At this time, the second motor is started intermittently periodically, so that the single rotation angle of the second motor is 120°. Since fixed limit plates are provided on both sides of the feeding tray, and the outer surface of the feeding tray is in contact with the inner wall of the fixed limit plate, the amount of material entering the fixed charging trough at a time can be more strictly controlled. The adjusting part can be started as needed, and the space inside the charging trough for loading materials can be adjusted through the adjusting plate, which not only further improves the applicability of the equipment, but also ensures the utilization rate of raw materials and further improves the utilization rate of energy.

[0017] 1. A rice bran hot air furnace for bio-granules, wherein two crushing rollers rotate in opposite directions, and the material is crushed under the crushing action of the crushing blades. Since the crushing blades are divided into two sections with the same length and opposite rotation directions, the crushing force is increased. At the same time, as the crushing blades rotate, the material can be transferred to the middle position of the refinement box. When the crushing force needs to be adjusted according to the type of crushed material, the adjusting part is started. The adjusting part changes the distance between the two crushing rollers through the adjusting cylinder, thereby obtaining different crushing forces, so that the equipment can provide heat source with different combustion sources as raw materials, and the combustion utilization rate of the raw materials is better guaranteed.

[0018] 2. In the rice bran hot air furnace for bio-granules, the crushed materials with qualified sizes pass through the leakage plate and fall into the interior of the loading trough under the guiding effect of the guide plate. At this time, the second motor is started intermittently periodically, so that the single rotation angle of the second motor is 120°. Since fixed limit plates are provided on both sides of the feeding tray, and the outer surface of the feeding tray is fitted with the inner wall of the fixed limit plate, the amount of material entering the fixed loading trough at a time can be more strictly controlled. The adjusting part can be started as needed, and the space inside the loading trough for loading materials can be adjusted by the adjusting plate, which not only further improves the applicability of the equipment, but also ensures the utilization rate of raw materials and further improves the utilization rate of energy.
