Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a high-efficiency screening device for biomass briquette fuel production. Background Art

[0002] Biomass briquette fuel mainly refers to materials such as straw, tree cellulose (lignin for short), agricultural product processing industry scraps, agricultural and forestry waste, and livestock manure and waste in the process of animal husbandry production, except for grain and fruit. Biomass briquette fuel will be screened by screening equipment during production;

[0003] In the process of using the existing screening device, the screening holes of most screening plates are fixed, resulting in a fixed screening size. When the screening size needs to be adjusted, the screening plate needs to be replaced, which affects the production efficiency.

[0004] At the same time, in wet seasons, when screening materials, moisture is likely to occur, causing the materials to adhere to the outer surface of the screening plate and the screening holes, resulting in reduced screening efficiency;

[0005] Therefore, the present application provides a high-efficiency screening device for biomass briquette fuel production to meet the demand. Utility Model Content

[0006] The purpose of the utility model is to solve the problems existing in the above-mentioned background technology, and to propose a high-efficiency screening device for biomass briquette fuel production.

[0007] The technical problem to be solved by the utility model is to provide a high-efficiency screening device for biomass briquette fuel production to solve the problem that the screening plate needs to be replaced when the size of the screening material is adjusted in the existing high-efficiency screening device for biomass briquette fuel production, and the screening material is easy to adhere to the outer surface of the screening plate in humid seasons.

[0008] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0009] A high-efficiency screening device for biomass briquette fuel production, comprising: a screening device body, a movable door is installed on the front of the screening device body, a discharge port is embedded below the right side surface of the screening device body, a feed hopper is embedded at the top of the screening device body, a vibration motor is fixedly connected to the left side of the screening device body, support blocks are fixedly connected to the left and right sides of the inner wall of the screening device body, a first filter plate is arranged above the support block, electric telescopic rods are fixedly connected to the left and right sides of the inner wall of the first filter plate, a second filter plate is fixedly connected to the output end of the electric telescopic rod, and a heating fan is fixedly connected to the top of the right side surface of the screening device body.

[0010] Preferably, guide plates are fixedly connected to the left and right sides of the top of the second filter plate, and the guide plates are made of rubber.

[0011] Preferably, a spring is fixedly connected between the first filter plate and the support block, and the vibration output end of the vibration motor is tightly fitted to the left side of the bottom of the first filter plate.

[0012] Preferably, the bottom surface of the inner wall of the screening device body is inclined downward from left to right and extends into the discharge port.

[0013] Preferably, a rotating nozzle base is fixedly connected to the left and right sides of the top of the inner wall of the screening device body, the rotating nozzle base is inclined toward the middle of the first filter plate, a nozzle is arranged at the bottom end of the rotating nozzle base, and the heating fan and the rotating nozzle base are connected.

[0014] Preferably, the nozzle is embedded in the rotating nozzle base at an inclined angle.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] In the above scheme, by setting an electric telescopic rod, when the size of the screening material needs to be adjusted, the user can start the electric telescopic rod to drive the second filter plate to move left and right. During the left and right movement of the second filter plate, the filter holes of the second filter plate will be staggered with the filter holes of the first filter plate, so as to adjust the filtering size of the first filter plate and the second filter plate, thereby adapting to screening with different requirements.

[0017] In the above scheme, by setting up a nozzle, during the screening process of fuel materials in humid seasons, it is easy to adhere to the first filter plate and the second filter plate, which affects the screening efficiency. Starting the heating fan will transport the hot air to the rotating nozzle base and spray it out through the nozzle. The hot air sprayed out by the nozzle will generate thrust to drive the rotating nozzle base to rotate, so that the hot air is blown 360 degrees through the nozzle to the first filter plate and the second filter plate area, making it difficult for the fuel material to adhere to the outer surfaces of the first filter plate and the second filter plate, thereby improving the screening efficiency.

DETAILED DESCRIPTION

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The utility model provides a high-efficiency screening device for biomass briquette fuel production, which includes: a screening device body 1, a movable door 101 is installed on the front of the screening device body 1, a discharge port 103 is embedded below the right side of the screening device body 1, a feed hopper 102 is embedded at the top of the screening device body 1, a vibration motor 104 is fixedly connected to the left side of the screening device body 1, support blocks 2 are fixedly connected to the left and right sides of the inner wall of the screening device body 1, a first filter plate 202 is arranged above the support block 2, an electric telescopic rod 203 is fixedly connected to the left and right sides of the inner wall of the first filter plate 202, a second filter plate 204 is fixedly connected to the output end of the electric telescopic rod 203, and a heating fan 4 is fixedly connected to the upper right side of the screening device body 1;

[0026] When the screening size needs to be adjusted, the user can start the electric telescopic rod 203 to drive the second filter plate 204 to move left and right, so that the filter holes of the first filter plate 202 and the filter holes of the second filter plate 204 are staggered or overlapped, thereby adjusting the filtering size of the first filter plate 202 and the second filter plate 204, so that materials of different sizes need to be screened without replacing the filter plate.

[0027] In this embodiment, Figure 2-Figure 4 As shown;

[0028] The left and right sides of the top of the second filter plate 204 are fixedly connected with guide plates 205, and the guide plates 205 are made of rubber;

[0029] The guide plate 205 facilitates the material passing through the feed hopper 102 to flow to the second filter plate 204 for screening, and the guide plate 205 is made of rubber material to facilitate the second filter plate 204 to deform when it moves left and right through the electric telescopic rod 203 to fit the inner wall of the screening device body 1;

[0030] A spring 201 is fixedly connected between the first filter plate 202 and the support block 2, and the vibration output end of the vibration motor 104 is tightly fitted to the left side of the bottom of the first filter plate 202;

[0031] When the material is screened by the first filter plate 202 and the second filter plate 204, starting the vibration motor 104 can drive the first filter plate 202 to vibrate, and the first filter plate 202 can increase the vibration amplitude through the elastic force of the spring 201, and the vibration of the first filter plate 202 will drive the second filter plate 204 to vibrate, thereby increasing the screening efficiency of the material;

[0032] The bottom surface of the inner wall of the screening device body 1 extends downwardly from left to right into the discharge port 103;

[0033] After screening, the material will fall to the bottom of the inner wall of the screening device body 1 and be guided to the discharge port 103 through the curvature of the bottom of the inner wall of the screening device body 1, so that it is difficult for the screening material to remain inside the screening device body 1;

[0034] The left and right sides of the top of the inner wall of the screening device body 1 are fixedly connected with a rotating nozzle base 3, the rotating nozzle base 3 is inclined toward the middle of the first filter plate 202, the bottom end of the rotating nozzle base 3 is provided with a nozzle 301, and the heating fan 4 is connected with the rotating nozzle base 3;

[0035] In the humid season, it is easy for materials to adhere to the outer surfaces of the first filter plate 202 and the second filter plate 203. The user can turn on the heating fan 4 to transport hot air to the rotating nozzle base 3 and spray it through the nozzle 301 to heat and dry the first filter plate 202 and the second filter plate 204, so that the materials screened in the humid season are not easy to adhere to the outer surfaces of the first filter plate 202 and the second filter plate 204.

[0036] The nozzle 301 is embedded in the rotating nozzle base 3 at an inclined angle;

[0037] When the nozzle 301 sprays hot air, thrust is generated to drive the rotating nozzle base 3 to rotate, so that the nozzle 301 delivers hot air 360 degrees to the first filter plate 202 and the second filter plate 204 area, thereby further improving the heating and dehumidification of the screened first filter plate 202 and the second filter plate 204 area.
