Technical Field

[0001] The utility model belongs to the technical field of powder bins, in particular to a powder bin with uniform feeding. Background Art

[0002] Powder silo is a device used to store and protect powdered materials. It can store various powdered materials required for industrial production, such as cement, lime, coal powder, mineral powder, etc. Powder silo can prevent powdered materials from being easily affected by factors such as sunlight exposure, rain, oxidation, humidity, etc. during storage, which may cause quality loss and waste, and ensure the quality and reliability of production raw materials. It is widely used in pharmaceutical, chemical, food, building materials, environmental protection and other industries.

[0003] At present, in the production process, it is often necessary to store a large amount of powder inside the powder silo.

DETAILED DESCRIPTION

[0024] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. 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.

[0025] like Figure 1 As shown, a powder silo with uniform feeding includes a frame 3, a silo 2 arranged on the frame 3, and an electric valve arranged on a discharge port 22 at the bottom of the silo 2;

[0026] like Figure 2 and Figure 3 As shown, when implemented, it includes: an adjusting bucket 4, which is arranged on the side of the silo 2, and a material guide channel 41 communicating with the silo 2 is arranged at the bottom of the adjusting bucket 4;

[0027] Specifically, a feed port 21 is provided on the surface of the silo 2, and a material guide channel 41 is divided into an inclined slide 411 and material receiving ports 412 provided on both sides of the inclined slide 411. The material receiving port 412 on one side of the material guide channel 41 is installed on the feed port 21 by fixing bolts, and the material receiving port 412 on the other side is connected to the material port at the bottom of the regulating bucket 4;

[0028] Specifically, the material guide channel 41 is provided with a diverter 5 in a port located on one side of the material port of the regulating bucket 4. The diverter 5 includes an adjusting rotating rod 51 rotatably arranged in the port and a plurality of diverter plates 52 connected to the adjusting rotating rod 51 in a circular shape. A pair of synchronous pulleys 54 are driven to rotate by starting a stepper motor, and one of the synchronous pulleys 54 drives the diverter 5, so that the powder material intermittently falls into the inclined slide 411 under the action of the diverter 5, so that the flow rate can be controlled, and blockage during feeding of the powder material is effectively avoided.

[0029] Specifically, a crushing wheel 53 is arranged on one side of the feed port 21 in the inclined slide 411 of the material guide channel 41, and a synchronous pulley 54 connected to the adjusting rotating rod 51 and the crushing wheel 53 is rotatably arranged on the outer wall of the inclined slide 411. The pair of synchronous pulleys 54 are connected by belts, and the synchronous pulleys 54 are driven by a stepping motor externally arranged on the inclined slide 411. The synchronous pulleys 54 drive the crushing wheel 53 to rotate, and crush the powder flowing into the inclined slide 411, so as to prevent the agglomerated powder from falling into the silo 2 and impacting the bottom of the silo 2.

[0030] like Figure 2 As shown, when implemented, it includes: a mixing rod 11, which is rotatably arranged in the silo 2, and a plurality of mixing blades 12 are arranged on the mixing rod 11. A scraping rod 13 is sleeved on the mixing rod 11, and scraping blades 14 are arranged on both sides of the scraping rod 13 to contact the inner wall of the silo 2;

[0031] Specifically, the mixing rod 11 is driven by a servo motor 1 externally arranged on the top surface of the silo 2, and the main shaft of the servo motor 1 is connected to the mixing rod 11. By starting the servo motor 1 to drive the mixing rod 11 to rotate, the mixing blades 12 on the mixing rod 11 stir and mix the powder, which can reduce the stratification of the powder in the silo 2 and effectively prevent the powder from piling up or agglomerating in the silo, thereby maintaining the uniformity of the powder; and when the mixing rod 11 rotates, the scraper rod 13 is synchronously driven to rotate, so that the scraper blades 14 on the scraper rod 13 scrape the inner wall of the silo 2, which can prevent the powder from sticking to the inner wall of the silo 2 and avoid waste of powder.

[0032] like Figures 1 to 3 As shown, in this embodiment, before the application is implemented, the stepper motor and servo motor 1 of suitable models are selected, and the crusher 53 and the diverter of suitable sizes are selected according to the material guide channel 41. The other components are selected and installed before implementation according to the actual needs of the site. In addition, it should be noted that the application document only improves the shortcomings of the existing powder silo, which is often blocked due to the accumulation of powders during feeding, and the powders are easy to agglomerate during feeding, which affects the uniformity of the powders, and does not involve other aspects; the working principle of the powder silo with uniform feeding is introduced as follows:

[0033] During installation and use, the on-site staff connects the powder conveying pipe to the feeding port of the regulating bucket 4 to convey the powder into the regulating bucket 4, and then starts the stepping motor to drive a pair of synchronous pulleys 54 to rotate, wherein one synchronous pulley 54 drives the diverter 5, so that the powder intermittently falls into the inclined slide 411 under the action of the diverter 5, thereby controlling the flow rate and effectively avoiding blockage during powder feeding; and the other synchronous pulley 54 drives the crushing wheel 53 to rotate, crushing the powder flowing into the inclined slide 411, thereby preventing the agglomerated powder from falling into the silo 2 and impacting the bottom of the silo 2;

[0034] After the powder falls into the silo 2, the servo motor 1 is started to drive the mixing rod 11 to rotate, so that the mixing blades 12 on the mixing rod 11 stir and mix the powder, which can reduce the stratification of the powder in the silo 2 and effectively prevent the powder from piling up or agglomerating in the silo, thereby maintaining the uniformity of the powder; and when the mixing rod 11 rotates, the scraper rod 13 is synchronously driven to rotate, so that the scraper blades 14 on the scraper rod 13 scrape the inner wall of the silo 2, which can prevent the powder from sticking to the inner wall of the silo 2 and avoid wasting the powder.

[0035] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
