Description

Technical Field

[0001] The utility model relates to the technical field of conveying bins, in particular to a dust-proof powder feeding and conveying bin. Background Art

[0002] Activated carbon is a specially treated carbon. The organic raw material is heated in an air-tight condition to reduce the non-carbon components. It then reacts with the gas, eroding the surface to produce a well-developed microporous structure, which has a good adsorption effect. It is usually in powder or granular form. During the activated carbon production process, a conveying bin is often used to store and transport the activated carbon.

[0003] The Chinese patent authorization announcement number is CN217920484U, and its name is a dust-proof powder feeding and conveying bin, which includes a bin body, and shielding mechanisms are provided on both sides of the top of the bin body, and the shielding mechanisms include a cover plate, an arc-shaped rod fixed to the bottom of the cover plate, a spring sleeved and slid on the outer wall of the arc-shaped rod, and a limit block provided at the bottom of the arc-shaped rod. A discharging mechanism is fixed to the bottom of the bin body, and the discharging mechanism includes a square tube, an inclined block provided at the bottom of the square tube, a servo motor installed on the outer wall of one side of the square tube, and a fixing frame fixed to the inner walls of both sides of the square tube. The utility model uses the shielding mechanism provided, and when the powder is poured, the bag mouth of the powder presses the two cover plates to flip downward, so that the bag mouth extends into the bin body for pouring and is shielded by the cover plates. When the pouring is completed, the two cover plates are pushed by the spring to close each other at the top of the bin body, which can effectively reduce the powder from floating out of the bin body and effectively improve the situation of dust polluting the air.

[0004] The shortcomings of the above-mentioned prior art solution are: although the above-mentioned solution can block the bin opening by the cover plate when the powder is poured, when the pouring is completed, the two cover plates are pushed by the spring to close each other, thereby reducing the phenomenon of powder floating out of the bin body, but when the activated carbon powder is put into the device, due to the problem of the storage environment, the powder will be agglomerated. When the agglomerated powder enters the interior of the device, it is easy to cause blockage during subsequent discharge, which is not conducive to the conveying operation. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-3As shown, a dust-proof powder feeding and conveying bin comprises a storage bin 1, a feeding pipe 2 is arranged on the top of the storage bin 1, a discharging pipe 3 is arranged on the bottom of the storage bin 1, a magnetic control valve is arranged inside the discharging pipe 3, a feeding pipe 4 connected to the output end of the discharging pipe 3 is arranged obliquely, a spiral feeding shaft 5 is rotatably arranged inside the feeding pipe 4, a discharging groove 6 is arranged on the outer side of the lowest end of the feeding pipe 4, a discharging motor 7 is arranged at the end of the feeding pipe 4 away from the discharging groove 6, negative pressure fans 8 are symmetrically arranged on both sides of the storage bin 1, and the negative pressure fans 8 are located above the pulley 17, a dust cover 9 is arranged on the input end of the negative pressure fan 8, and a dust cover 9 matching the negative pressure fan 8 is symmetrically arranged on the upper end of the inner wall of the storage bin 1 The protective plate 10 is tilted downward. When the device is in use, the material is put into the storage bin 1 through the feed pipe 2, and the negative pressure fan 8 is started, so that the inside of the storage bin 1 is in a certain negative pressure state, thereby accelerating the material discharge speed. The dust cover 9 can effectively prevent the activated carbon powder from escaping through the air duct of the negative pressure fan 8. The protective plate 10 tilted downward effectively avoids a large amount of activated carbon powder from being thrown onto the dust cover 9 during feeding, causing the dust cover 9 to be blocked. When it is necessary to discharge the material, the discharge motor 7 is started, the magnetic control valve is opened, and the discharge motor 7 drives the spiral feeding shaft 5 to transport the activated carbon powder, and the activated carbon powder is discharged from the discharge trough 6 opened on the feed pipe 4;

[0023] The crushing assembly also includes three groups of lifting grooves 11 opened on the inner walls of both sides of the storage bin 1, a bulk material plate 12 slidably arranged inside the lowermost lifting groove 11, a crushing plate 13 slidably arranged inside the two upper lifting grooves 11, and the crushing plates 13 are staggered up and down, a plurality of groups of pointed blocks 14 are arranged on the top of the crushing plates 13, a guide telescopic rod 15 arranged inside the lifting groove 11 for supporting the bulk material plate 12 and the crushing plate 13, a spring 16 sleeved inside the guide telescopic rod 15, and a power assembly, the power assembly includes three groups of pulleys 17 arranged on the outside of the storage bin 1, and the three groups of pulleys 17 are triangularly distributed, a crawler 18 sleeved on the outside of the pulleys 17, a servo motor 19 arranged on the outside of one group of pulleys 17, and a cam 20 that is fitted inside the storage bin 1 and connected to the side of the three groups of pulleys 17 away from the servo motor 19, and the cam 20 is respectively located at the bulk material plate 12 and the crushing plate 13. Below the material plate 12 and the crushing plate 13, when there are lumps in the activated carbon powder, the agglomerated powder will hit the top crushing plate 13 when falling, and the agglomerated powder can be crushed by the impact force generated by the collision in combination with the sharp-angle block 14. The staggered crushing plate 13 further prolongs the contact time between the agglomerated powder and the sharp-angle block 14, thereby ensuring the crushing effect. The crushed powder is dispersed and falls onto the bulk plate 12. The bulk plate 12 is provided with holes that can evenly disperse the powder to the bottom of the storage bin 1 to avoid concentrated accumulation, and the servo motor 19 can synchronously drive the three sets of pulleys 17 to rotate through the crawler 18. The rotation of the pulley 17 can make the raised end of the cam 20 intermittently contact the bulk plate 12 and the crushing plate 13, thereby causing the bulk plate 12 and the crushing plate 13 to vibrate intermittently to avoid powder residue on them.

[0024] In this embodiment, specifically, a support frame 21 is provided at the bottom edge of the storage bin 1 to support the entire device and ensure the overall stability of the device when working.
