Description

Sludge fuel particle screening device

technical field

The utility model relates to the technology of sludge synthetic fuel, in particular to a particle sieving device for sludge synthetic fuel.

Background technique

Sludge synthetic fuel is an environmentally friendly fuel formed by mixing sludge produced after sewage treatment with a certain proportion of straw powder and wood powder. The production process of sludge synthetic fuel is: first use the sludge synthetic fuel molding machine to press the mixed raw materials into cylindrical particles with a diameter of 3-6mm, then dry and pack through the dryer.

However, in the production process, a small amount of cylindrical particles will be broken or even turned into powder, which will reduce the drying efficiency. At the same time, it is easy to generate dust during loading and unloading and use, which is not conducive to clean production environment and safety. Therefore, it needs to be pre-screened and processed again. , sieve out the remaining particulate fuel to pack and leave the factory.

The conventional sieving device is a sieve bed with a vibrating motor installed at the lower part of the screen placed horizontally; this kind of sieving device needs to manually transfer the sieved particles to the packaging machine for processing, and because the vibrating motor is placed at the lower part of the sieve, when screening It is easy to vibrate the biomass particles and some of them are easy to jump out of the screen, so it cannot be matched with the existing automatic production line of sludge synthetic fuel, so there is an urgent need for improvement.

Utility model content

The technical problem to be solved by the utility model is to overcome the deficiency of the above-mentioned background technology and provide a sludge fuel particle sieving device, which can be effectively matched with the automatic production line of sludge synthetic fuel.

For realizing above object, the technical scheme that the utility model adopts is:

Sludge fuel particle screening device, including a frame fixed on the frame, a sieving bed positioned on the frame with a screen, and a vibrating motor installed on the sieving bed; it is characterized in that: the frame and the sieving The beds are all tilted and positioned on the frame at a certain angle; the sieving bed is positioned on the frame through the shaft hole matching structure, and the frame supports the sieving bed through the guide wheel structure; the vibration motor is installed on the sieving bed rear side.

The certain angle of inclination is an included angle of 30-40 degrees with the horizontal plane.

The shaft hole matching structure includes a guide rod fixed on the side of the sieving bed and a guide sleeve fixed on the frame and plugged with the guide rod.

The length direction of the guide rod is consistent with the length direction of the sieve bed.

Springs with damping and vibration-increasing effects are also arranged between the two ends of the sieving bed in the length direction and the frame.

The guide wheel shaft in the guide wheel structure is fixed on the edge of the sieving bed; the outer peripheral surface of the guide wheel presses against the upper surface of the frame.

The beneficial effects of the utility model are:

Due to the slanted arrangement of the sieve bed, the broken particles and powders fall from the sieve holes during operation, and the complete particles are exported from the front of the sieve by gravity, which not only realizes the complete matching of the automatic production line, but also significantly improves the production capacity. Efficiency, but also greatly reduce the work intensity of the operating staff; widely welcomed by the production enterprises.

detailed description

The utility model will be further described below in conjunction with the accompanying drawings of the description, but the utility model is not limited to the following examples.

In the sludge fuel particle sieving device as shown in the figure, the frame 2 is fixed on the frame 1, and the sieving bed 3 with the screen cloth 9 and the vibrating motor 4 can reciprocate linearly (the length of the moving direction is the same as the length of the sieving bed). Orientation) positioned on the frame.

The mesh size of the sieve can be determined according to needs; it is recommended to choose 3-6mm.

The above structure is similar to the existing sieve bed.

The improvement of the utility model is that: the frame and the sieve bed are positioned on the frame at an inclined angle; the inclined angle is recommended to be an angle of 30-40 with the horizontal plane; The rear side of the sieve bed (left side in the figure) can effectively eliminate the phenomenon of biomass particles being broken and particles jumping out of the sieve. The sieving bed is also positioned on the frame through the shaft-hole matching structure, and the frame supports the sieving bed through the guide wheel structure.

The shaft-hole matching structure is a guide rod 5 fixed on the side of the sieving bed and a guide sleeve 6 fixed on the frame and mated with the guide rod; or, the guide rod is fixed on the frame and mated with the guide rod The guide sleeve is fixed on the side of the sieving bed; it can be determined according to the needs. The length direction of the guide rod is consistent with the length direction of the sieve bed.

Springs 6 are also arranged between the two ends of the sieving bed in the length direction and the frame, which can obtain a better buffering effect.

In the structure of the guide wheel, the shaft of the guide wheel is fixed on the edge of the sieving bed; the outer peripheral surface of the guide wheel is pressed against the upper surface of the frame; thus, the weight of the sieving bed and the raw materials during work can all be borne by the frame.

Figure 3 shows the matching position of the utility model in the automatic production line of sludge synthetic fuel; the granular fuel output by the dryer 11 continuously flows into the sieving bed, and the fuel particles after vibrating sieving are input from the right side of the sieving bed The granule packaging machine 12 packs, and the broken granules and powder falling from the sieve of the sieve bed can be regularly collected and reused for pressing the granule fuel.
