Description

Technical Field

[0001] This utility model belongs to the field of powder conveying technology, and in particular relates to a novel powder conveying and gas collection device. Background Technology

[0002] With the booming development of modern manufacturing, such as chemical, food, building materials, and pharmaceutical industries, the use of powder materials is becoming more and more widespread. In the chemical industry, a large number of powdered catalysts and additives need to be transported between different production units. In the food industry, the processing and transportation of powders such as flour, sugar powder, and milk powder are also extremely frequent. These industries have increasingly higher requirements for production efficiency and product quality. Traditional powder conveying methods cannot meet the needs of large-scale, efficient, and clean production. Therefore, more advanced gas collection devices are needed to cooperate with powder conveying.

[0003] In existing powder conveying devices, some highly viscous materials will accumulate on the silo walls. Over time, these attached materials will increase and cannot be carried out during normal unloading, resulting in material loss. Utility Model Content

[0004] This invention addresses the problem in the prior art where highly viscous materials accumulate on the walls of silos, and over time, this accumulated material cannot be carried away during normal unloading, leading to material loss. The following technical solution is proposed:

[0005] A novel powder conveying and gas collection device includes: a silo pump, a conveying pipe fixedly connected to the bottom end of the silo pump, an exhaust valve fixedly connected to the top edge of the silo pump, a silo connected to the center of the top of the silo pump via a connecting pipe, a cross support plate fixedly installed on the inner wall of the silo, a motor fixedly installed at the center of the top of the cross support plate, a rotating shaft fixedly installed on the output shaft of the motor, a crossbeam fixedly installed at the bottom end of the rotating shaft, brackets fixedly installed at both ends of the crossbeam, scrapers fixedly installed on one side of each bracket, and a stirring paddle fixedly sleeved on the outer surface of the rotating shaft.

[0006] As a preferred embodiment of the above technical solution, four support rods are symmetrically installed at equal intervals around the center point on the top of the inner wall of the silo pump. The same No. 1 dispersion cone is fixedly sleeved between the outer surfaces of the four support rods. The same No. 1 funnel is fixedly sleeved at the bottom of the No. 1 dispersion cone on the outer surfaces of the four support rods. A No. 2 dispersion cone is fixedly sleeved at the bottom of the No. 1 funnel on the outer surfaces of the four support rods. A No. 2 funnel is fixedly sleeved at the bottom of the No. 2 dispersion cone on the outer surfaces of the four support rods.

[0007] As a preferred embodiment of the above technical solution, the scraper is made of rubber.

[0008] As a preferred embodiment of the above technical solution, each of the four support rods is movably fitted with a fixing sleeve, each of the four fixing sleeves is fixedly installed at the top of the inside of the pump, each of the four fixing sleeves has a spring fixedly installed at the bottom of its inside, and the other end of each of the four springs is fixedly installed at the top of the corresponding support rod.

[0009] As a preferred embodiment of the above technical solution, a connecting channel is provided in the middle of the cross support plate, and the rotating shaft passes through the connecting channel and connects to the output shaft of the motor.

[0010] As a preferred embodiment of the above technical solution, the scraper and the bracket are fixedly installed by screws.

[0011] The beneficial effects of this utility model are as follows:

[0012] (1) By installing a scraper structure to scrape off the material attached to the inner wall of the silo, material waste is avoided. Furthermore, by rotating the agitator to break up the clumps of material, the problem of clumps blocking the discharge port of the silo is avoided, allowing the material to be smoothly transferred into the silo pump.

[0013] (2) By dispersing the material entering the silo pump, the density between materials is reduced and the material flow time is extended, which improves the drying efficiency of the material and prevents the relatively moist material from continuing to clump. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Example

[0020] This utility model provides a novel powder conveying and gas collection device, such as... Figures 1 to 4 As shown, it includes a silo pump 1, a conveying pipe 2 fixedly connected to the bottom of the silo pump 1, an exhaust valve 3 fixedly connected to the top edge of the silo pump 1, a silo 4 connected to the top center of the silo pump 1 via a connecting pipe, an air inlet valve group installed inside the silo 4, a discharge valve installed at the connection between the conveying pipe 2 and the silo pump 1, and a discharge valve installed at the connection between the silo pump 1 and the connecting pipe (this is existing technology and will not be elaborated further here). A cross support plate 5 is fixedly installed on the inner wall of the silo 4, a motor 6 is fixedly installed at the top center of the cross support plate 5, a rotating shaft 7 is fixedly installed on the output shaft of the motor 6, a crossbeam 8 is fixedly installed at the bottom of the rotating shaft 7, brackets 9 are fixedly installed at both ends of the crossbeam 8, scrapers 10 are fixedly installed on one side of each bracket 9, and an agitator 11 is fixedly sleeved on the outer surface of the rotating shaft 7.

[0021] like Figure 1 and Figure 4 As shown, four support rods 12 are symmetrically installed at equal intervals around the center point on the top of the inner wall of the silo pump 1. The same first dispersion cone 13 is connected to the outer surface of the four support rods 12 by a fixing sleeve 18. The same first funnel 14 is connected to the outer surface of the four support rods 12 at the bottom of the first dispersion cone 13 by a fixing sleeve 18. The second dispersion cone 15 is connected to the outer surface of the four support rods 12 at the bottom of the first funnel 14 by a fixing sleeve 18. The second funnel 16 is connected to the outer surface of the four support rods 12 at the bottom of the second dispersion cone 15 by a fixing sleeve 18. By dispersing the material entering the silo pump 1, the density between the materials is reduced and the material flow time is extended, thereby improving the drying efficiency of the material and preventing the relatively moist material from continuing to clump.

[0022] like Figure 2 and Figure 3 As shown, the scraper 10 is made of rubber. The scraper 10 scrapes away the material on the inner wall of the material yard, thus avoiding damage to the inside of the material hopper 4 when the scraper 10 is in contact with the inner wall of the material hopper 4.

[0023] like Figure 1 and Figure 4 As shown, each of the four support rods 12 has a fixed sleeve 18 movably fitted onto its outer surface. Each of the four fixed sleeves 18 is fixedly installed at the top of the inside of the silo pump 1. Each of the four fixed sleeves 18 has a spring 17 fixedly installed at its bottom. The other end of each of the four springs 17 is fixedly installed at the top of the corresponding support rod 12. The springs 17 alleviate the impact force of the material during the descent process, effectively reducing the physical damage to the No. 1 dispersion cone 13 and extending the service life of the No. 1 dispersion cone 13.

[0024] like Figure 2 and Figure 3As shown, a connecting channel is provided in the middle of the cross support plate 5. The rotating shaft 7 passes through the connecting channel and connects to the output shaft of the motor 6, providing installation space for the connection between the output shaft and the rotating shaft 7, so that the output shaft and the rotating shaft 7 can be stably connected.

[0025] like Figure 2 and Figure 3 As shown, the scraper 10 and the bracket 9 are fixedly installed with screws. The screws make the bracket 9 and the scraper 10 securely installed, so that the scraper 10 and the bracket 9 can work stably.

[0026] Working Principle: When using the powder conveying and air-collecting device, the discharge valve is opened, and the material flows from the hopper 4 into the hopper pump 1. First, the motor 6 is started, and the stirring paddle 11 rotates to break up any lumps of material, preventing clogged discharge ports of the hopper 4 and allowing the material to flow smoothly into the hopper pump 1. Simultaneously, the scraper 10 removes residual material adhering to the inner wall, preventing material waste caused by material adhering to the inner wall of the hopper 4 as the material volume decreases. At the same time as the material enters the hopper pump 1, the exhaust valve 3 is opened to prevent air from accumulating inside the hopper pump 1 with the material, thus preventing an increase in internal air pressure. When the material falls onto the surface of the first dispersing cone 13, the spring 17 is compressed by pressure. At the same time, the material disperses along the surface of the first dispersing cone 13 and slides down. Then it slides down along the surface of the first funnel 14 into the second dispersing cone 15, and then falls into the surface of the second funnel 16 to continue sliding down. This prolongs the material flow time, improves the drying efficiency of the material, and prevents the relatively moist material from continuing to clump. When all the material has fallen into the silo pump 1, the discharge valve and exhaust valve 3 are closed, and the discharge valve and air inlet valve group are opened. The material in the silo pump 1 is compressed by air and flows out from the discharge valve into the conveying pipeline 2.

[0027] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
