Description

Technical Field

[0001] The utility model relates to the technical field of powder storage, in particular to a powder bin of a concrete mixing station. Background Art

[0002] The powder silo is a temporary storage device configured above the mixer to improve production efficiency, waiting to be mixed with a batch of well-proportioned materials to reflect the advantages of the high-efficiency mixer. The main powder materials stored in the powder silo are lime and fine sand, which are generally transported to the powder silo by air delivery. The general powder silo transports cement ash into the gas pipeline for temporary storage, and only relies on the filter screen at the top of the powder silo to filter the ash and exhaust. The cement ash exists in the gas pipeline in a state of gray gas. Long-term gray gas filtration is easy to block the filter screen, and the gas in the powder silo can only enter but not exit. For this reason, a dust removal device is generally installed inside the powder silo.

[0003] However, traditional dust removal devices usually have a continuously rotating brush plate installed on the lower surface of the filter plate. Although it has a certain dust removal effect, the continuous rotation of the brush plate will cause a certain obstruction to the upward airflow, thereby reducing the filtration speed of the ash gas and affecting the normal transportation of the powder.

[0004] In addition, when the dust removal device of the powder silo of the existing concrete mixing station processes the powder delivered by air, some of the powder will adhere to the upper end of the inner wall of the powder silo in the form of dust, which is difficult to completely remove. At the same time, the powder is easy to condense into blocks before transportation and when it accumulates in the powder silo, resulting in unsatisfactory subsequent powder mixing effect. Utility Model Content

[0005] The purpose of the utility model is to provide a powder silo for a concrete mixing station to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a powder silo of a concrete mixing station, comprising a storage silo and a feed pipe, the upper end of the storage silo is fixedly connected to the feed pipe, the feed pipe is fixedly connected to a filter plate, one side of the storage silo is fixedly connected to a support frame, the upper end of the support frame is fixedly connected to a drive motor, a drive gear disc is provided in the middle of the drive motor, one side of the drive gear disc is meshed and connected to a first gear disc, one side of the first gear disc is fixedly connected to a drive shaft, one end of the drive shaft is fixedly connected to a first bevel gear, one side of the first bevel gear is meshed and connected to a second bevel gear, the second bevel gear is fixedly connected to a rotating shaft, and the upper end of the rotating shaft is fixedly connected to a cleaning brush.

[0007] Preferably, a stirring rod is fixedly connected to the rotating shaft, and the stirring rod abuts against the inner wall of the storage bin.

[0008] Preferably, the upper end of the feed pipe is clamped with a cover plate.

[0009] Preferably, a dustproof frame is sleeved on the outer side of the driving shaft, and the dustproof frame is fixedly connected to the inner wall of the storage bin.

[0010] Preferably, the bottom end of the storage bin is fixedly connected to a discharge pipe.

[0011] Preferably, a plurality of legs are fixedly mounted on the bottom end of the storage bin.

[0012] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0013] First, the utility model can clean the filter plate by setting a driving motor and a cleaning brush. The driving motor rotates, and the driving toothed disc drives the first toothed disc to rotate through meshing. When the toothless side of the driving toothed disc contacts the toothless side of the first toothed disc, the first toothed disc stops rotating and realizes intermittent rotation. This drives the driving shaft to rotate intermittently. The driving shaft drives the second bevel gear to rotate through the first bevel gear, and then the rotating shaft drives the upper cleaning brush to rotate intermittently. The intermittent rotation of the cleaning brush not only cleans the dust on the filter plate, but also avoids the generation of reverse airflow, prevents airflow convection inside the powder bin, and ensures the normal transportation of powder.

[0014] Second, the utility model can avoid powder agglomeration by providing a rotating shaft and a stirring rod. The rotation of the rotating shaft drives the stirring rod to rotate at the same time. The rotation of the stirring rod disperses the internal powder to avoid the accumulation and agglomeration of powder inside the storage bin. At the same time, the stirring rod is in close contact with the inner wall of the storage bin when rotating, thereby scraping off the powder adhered to the inner wall of the storage bin to avoid long-term dust adhesion and accumulation.

The driving motor 7 drives the driving gear disc 13 to rotate, and the driving motor 7 drives the driving gear disc 13 to rotate. The movable toothed disc 13 rotates and engages to drive the first toothed disc 9 to rotate. When the toothless side of the driving toothed disc 13 contacts the toothless side of the first toothed disc 9, the first toothed disc 9 stops rotating, thereby achieving the effect of intermittent rotation of the first toothed disc 9. The intermittent rotation of the first toothed disc 9 drives the drive shaft 10 to rotate intermittently. When the drive shaft 10 rotates intermittently, the first bevel gear 14 drives the second bevel gear 15 to rotate. The rotation of the second bevel gear 15 drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the upper cleaning brush 16 to rotate intermittently.

[0022] A stirring rod 17 is fixedly connected to the rotating shaft 11, and the stirring rod 17 abuts against the inner wall of the storage bin 1. When the rotating shaft 11 rotates, the stirring rod 17 is driven to rotate at the same time. The stirring rod 17 rotates to disperse the internal powder to avoid the accumulation and agglomeration of the powder inside the storage bin 1. At the same time, the stirring rod 17 is in close contact with the inner wall of the storage bin 1 when rotating, so as to scrape off the powder adhered to the inner wall of the storage bin 1 to avoid long-term dust adhesion and accumulation.

[0023] The upper end of the feed pipe 2 is clamped with a cover plate 4, and the feed pipe 2 is opened and closed through the cover plate 4.

[0024] The outer side of the driving shaft 10 is sleeved with a dustproof frame 8 , and the dustproof frame 8 is fixedly connected to the inner wall of the storage bin 1 , so that the dustproof frame 8 can prevent the powder from accumulating and adhering to the driving shaft 10 .

When the toothless side of the driving toothed disc 13 contacts the toothless side of the first toothed disc 9, the first toothed disc 9 stops rotating, thereby achieving the effect of intermittent rotation of the first toothed disc 9. The intermittent rotation of the first toothed disc 9 drives the driving shaft 10 to rotate intermittently. When the driving shaft 10 rotates intermittently, the first bevel gear 14 drives the second bevel gear 15 to rotate. The rotation of the second bevel gear 15 drives the rotating shaft 11 to rotate, and the rotating shaft 11 drives the upper cleaning The brush 16 rotates intermittently. By intermittently rotating the cleaning brush 16, while cleaning the dust on the filter plate 12, no reverse airflow is generated, avoiding the convection of airflow inside the powder silo, thereby ensuring the normal transportation of the powder. When the rotating shaft 11 rotates, the stirring rod 17 is driven to rotate at the same time. The stirring rod 17 rotates to disperse the internal powder to avoid the accumulation and agglomeration of the powder inside the storage silo 1.
