Description

Technical Field

[0001] The utility model relates to the technical field of wheat bran crushing, in particular to a crushing device for preventing a discharge port from being blocked. Background Art

[0002] During the wheat bran processing, the wheat bran needs to be dried and crushed in order to further grind the wheat bran. In traditional processing plants, independent dryers and crushers are used for drying and crushing, and the wheat bran needs to be transported between the dryer and the crusher. This not only occupies a large area, but also has discontinuous production and a long processing cycle, and is not suitable for large-scale wheat bran processing. Therefore, the drying and crushing device was born, which integrates drying and crushing, saves time, shortens the processing cycle, and improves production efficiency.

[0003] For example, the Chinese patent authorization announcement number: CN 112473919 B discloses a wheat bran crushing device and a processing method thereof, which performs pre-crushing through an upper crushing mechanism, so that the wheat bran is crushed to a certain extent, but not completely crushed, because after the wheat bran is completely crushed, it will drive the completely crushed wheat bran and dust to be adsorbed together when passing through the induced draft to suction dust, thus resulting in poor dust removal and separation effect. The present invention first performs pre-crushing to improve the dispersibility of the wheat bran and is in a semi-crushed state at the same time, so that it will not be adsorbed by the induced draft, and the effect of separation from the dust is good.

[0004] However, the above-mentioned patents are prone to scattering debris during use, endangering the service life of the staff, and most of the discharging ports of the crushing devices are prone to blockage, resulting in poor discharge effect, affecting normal use. Utility Model Content

[0009] In a preferred embodiment, a filter mesh cover is provided inside the processing box on the outside of the dust hood, and a filter screen plate and an activated carbon filter layer are fixedly installed inside the filter box. The setting of the filter mesh cover can prevent the wheat bran from being sucked out through the dust hood, and the filter box can filter out small particles or dust to prevent dust from entering the air and endangering human health.

[0010] In a preferred embodiment, an air inlet is provided at one end of the piston cylinder, and the air inlet is connected to the output end of the dust suction fan, and an electric heating wire is provided at the piston cylinder. An exhaust port is provided at one end of the piston cylinder, and the exhaust port is connected to a blowing plate arranged on the inner wall of the processing box through a pipeline.

[0025] In a preferred embodiment, a filter screen cover 21 is provided inside the treatment box 3 on the outside of the dust cover 6, and a filter screen plate and an activated carbon filter layer are fixedly installed inside the filter box 8.

[0026] In a preferred embodiment, an air inlet 22 is provided at one end of the piston cylinder 10, and the air inlet 22 is connected to the output end of the dust suction fan 9, and an electric heating wire 23 is provided at the piston cylinder 10, and an exhaust port 24 is provided at one end of the piston cylinder 10, and the exhaust port 24 is connected to a blowing plate 25 arranged on the inner wall of the processing box 3 through a pipeline, and both the air inlet 22 and the exhaust port 24 are provided with a one-way valve, and a pressure valve 27 is provided at the exhaust port 24, so that the gas discharged from the filter box 8 can enter the piston cylinder 10 through the air inlet 22, so that the air pressure inside the piston cylinder 10 increases, and when the air pressure increases to a certain level, the gas is discharged into the blowing plate 25 in the processing box 3 through the exhaust port 24, and air is blown into the processing box 3 through the blowing plate 25.

[0028] The working principle of the utility model is as follows: when in use, the wheat bran to be processed is put into the processing box 3 through the feed port 14, the upper end of the feed port 14 is covered with a cover plate, and then the driving motor 18, the dust suction fan 9 and the electric heating wire 23 are turned on. After the driving motor 18 is turned on, it drives the rotating shaft 19 to rotate, and the rotating shaft 19 drives the stirring rod 20 to stir the materials inside the processing box 3. During the stirring process, the dust suction fan 9 can suck the dust particles inside the processing box 3 into the filter box 8 through the dust suction cover 6, and the dust can be filtered out by the filter box 8. The filtered gas enters the piston cylinder 10 through the pipeline and the air inlet 22. When in use, the pipeline 7 adopts a high-temperature resistant rubber hose to facilitate the shaking of the treatment box 3. The piston 11 inside the piston cylinder 10 moves to the left under the push of the gas pressure, so that the piston 11 drives the push rod 12 and the push plate 13 to move, so that the push plate 13 pushes the treatment box 3 to move to the left, so that the material inside the treatment box 3 rolls. When the push plate 13 moves to the leftmost end of the piston cylinder 10, it cannot move further. As the gas inside the piston cylinder 10 gradually The pressure inside the piston cylinder 10 increases, and the pressure inside the piston cylinder 10 gradually increases. When the pressure inside the piston cylinder 10 reaches the preset value of the pressure valve 27, the pressure valve 27 opens, and the gas inside the piston cylinder 10 is discharged into the blowing plate 25 inside the processing box 3 through the exhaust port 24. The gas inside the piston cylinder 10 is heated by the electric heating wire 23 to increase the temperature, so the gas blown out by the blowing plate 25 can dry the wheat bran. After the gas inside the piston cylinder 10 is discharged, the push plate 13 moves to the right driven by the spring 26. When the push plate 13 moves to the right, the processing box 3 loses the force of the push plate 13 and moves to the right, so that the material is constantly shaken during the stirring and mixing process, which can effectively improve the drying efficiency of the material. After the drying is completed, the solenoid valve 16 is opened, and the material enters the crushing knife group 5 through the material guide port 15, and the crushing knife group 5 is used to crush the material. The continuous shaking of the processing box 3 during the crushing process can also improve the crushing efficiency. After the crushing is completed, when the processing box 3 tilts to the left at a certain angle, the dust suction fan 9 is turned off, and then the sealing plate at the discharge port 17 is opened, and the material can be discharged from the discharge port 17.
