The utility model relates to a from clear formula multiple spot drum screening machine of unloading has following technological effect:

1) the fine particle materials after being sieved can be collected by arranging the packing auger, and the materials are unloaded at any position of the lower part of the shell or are unloaded at multiple points, so that the arrangement space of the equipment is greatly reduced, and the structure is compact.

2) And materials adhered to the blowing drum screen can be blown by arranging the blowing device. The screen cloth can not be blocked, and the screened materials are more uniform.

3) The internal spiral blades are arranged in the drum screen, so that the conveying and screening can be simultaneously carried out, in addition, the internal spiral blades and the packing auger are opposite in spiral direction, two materials can be separately discharged after being screened, and the process is simplified.

4) The screening of the device is carried out in the shell, no ash is leaked, and the device is environment-friendly and safe.

Drawings

The invention will be further explained with reference to the following figures and examples:

fig. 1 is a front view of the present invention.

FIG. 2 is a left side view of the present invention

Fig. 3 is a front view of the blowing device of the present invention.

Fig. 4 is a left side view of the middle blowing device of the present invention.

In the figure: the device comprises a speed reducing motor 1, a driving end face assembly 2, a feeding port 3, a roller screen 4, an inner spiral blade 5, a tail end face assembly 6, a blowing device 7, a first discharging port 8, a packing auger 9, a second discharging port 10, a shell 11, a first rotating shaft 12, a second motor 13, a gas collecting pipe 14, a gas distributing pipe 15 and a blowing nozzle 16.

Detailed Description

As shown in figure 1, the self-cleaning multi-point discharging drum screen comprises a shell 11, wherein a first rotating shaft 12 is installed in the shell 11, and the middle of the first rotating shaft 12 is integrally installed with a drum screen 4. The left and right ends of the first rotating shaft 12 extend out of the housing 11. One end of a first rotating shaft 12 is connected with the tail end face assembly 6, the other end of the first rotating shaft 12 is connected with a driving end face assembly 2, a speed reducing motor 1 is installed on one side of the driving end face assembly 2, the speed reducing motor 1 can drive the first rotating shaft 12 to rotate, and the first rotating shaft 12 drives the roller screen 4 to rotate. The inside spiral blade 5 that has welded in the cylinder screen cloth 4, the other end is carried from one end to material accessible inside spiral blade 5 in cylinder screen cloth 4, because be equipped with the sieve mesh on the cylinder screen cloth 4, through selecting the sieve mesh size, can carry and sieve different materials.

As shown in fig. 1, a charging opening 3 is installed above the left side of the housing 11, the discharging end of the charging opening 3 is connected with a transition chute ((the transition chute is not shown in the figure), the transition chute is inclined downwards, and the discharging end extends into the charging opening at the left end of the drum screen 4 (the left end and the right end of the drum screen 4 are completely opened).

A first discharge opening 8 is arranged at the position of the shell 11 below the discharge end of the roller screen 4. The material to be screened enters the inlet at the left end of the roller screen 4 through the feed inlet 3. After screening, large granule material flows out and falls through first discharge opening 8 from the export of cylinder screen 4 right-hand member.

An auger 9 is arranged in a shell 11 below the roller screen 4, and the auger 9 is driven to rotate by a second motor 13. One end of an outer spiral blade on the packing auger 9 is aligned with or close to the left of the discharge end of the roller screen 4 and is spaced from the first discharge opening 8 by a certain distance. The auger 9 is driven by a second motor 13 to move the fine particle materials falling from the roller screen 4 from right to left. And 8 left sides of first discharge opening are equipped with a plurality of second discharge openings 10, and the fritter material is unloaded through second discharge opening 10 after the screening.

The casing 11 is provided with a blowing device 7 which comprises a gas collecting pipe 14, and the gas collecting pipe 14 supplies air through a high-air-volume vortex fan. The gas collecting pipes 14 are distributed along the length direction of the shell 11, the lower ends of the gas collecting pipes 14 are connected with a plurality of gas distributing pipes 15, the end of each gas distributing pipe 15 is provided with a purging nozzle 16, and the purging nozzles 16 are opposite to the roller screen 4. The roller screen 4 is blown and swept by the blowing and sweeping nozzle 16 through the air supply of the large-air-volume vortex fan, so that the blockage of the roller screen 4 can be avoided.

The working principle and the process are as follows: the speed reducing motor 1 drives the roller screen 4 to rotate, materials enter the roller screen 4 through the feed inlet 3, the inner spiral blades 5 rotate to convey the materials to the tail, conveying and screening are carried out simultaneously, and the self-cleaning blowing device 7 sweeps the materials adhered to the screen. The large-lumpy materials are discharged through a discharge opening 8, and the screened small-lumpy materials are discharged at any position of the lower part of the shell after being collected by the outer spiral blade collecting device 9 in a rotating mode, so that multi-point discharging is achieved.
