Description

Technical Field

[0001] This utility model relates to a powder quality homogenization bin, which belongs to the technical field of chemical production, specifically to the quality homogenization of finished powder products. Background Technology

[0002] In addition to having certain requirements for product quality, chemical companies also require that the quality of products of the same specification be averaged so that customers who purchase the products can formulate usage standards based on product quality.

[0003] For example, gypsum powder is quite sensitive to temperature during use, so the quality of gypsum powder plays a decisive role in the initial setting time. If gypsum powder products of the same specification are of inconsistent quality, it will lead to deviations in the effect of use.

[0004] Therefore, before powdered materials leave the factory, products of the same specification are mixed and homogenized to ensure a high degree of consistency in product quality. Currently, the method used is generally to feed the material into a silo and mix it by stirring. However, this homogenization method requires a stirring shaft and a high-power motor, which is extremely energy-intensive. Furthermore, during the stirring process, some areas within the silo cannot be stirred, resulting in many dead zones and affecting the homogenization quality. Utility Model Content

[0005] To address one of the aforementioned technical deficiencies, this utility model provides a powder quality homogenization bin that offers high homogenization quality, high efficiency, low energy consumption, and low modification cost.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a powder quality homogenization bin, including a mixing bin, a discharge pipe, a discharge valve, a high-pressure air pipe, a guide hood, an inverted cone hood, a central pipe, and a high-pressure air source. The mixing bin is fixedly installed on the ground by a frame. The top of the mixing bin is provided with a bin cover and a material inlet on the bin cover. The bottom of the mixing bin is funnel-shaped and a discharge pipe is fixedly installed at the bottom end. A discharge valve is installed on the discharge pipe. The central pipe is a hollow tubular structure with open top and bottom ends. The top end of the central pipe is connected to the inner top surface of the bin cover through a top fixing component. An inverted cone hood is fixedly connected to the bottom end of the central pipe. The wall is fixedly connected to the inner wall of the bottom of the mixing silo by multiple first connecting plates. A guide hood is set directly below the inverted cone hood. The guide hood is a hollow cylindrical structure that is narrow at the top and wide at the bottom and open at both ends. The upper part of the outer wall of the guide hood is fixedly connected to the corresponding first connecting plate above by multiple second connecting plates. The lower part of the outer wall of the guide hood is fixedly connected to the outer wall of one end of the high-pressure air pipe by multiple third connecting plates. The other end of the high-pressure air pipe extends out of the mixing silo and is connected to the high-pressure air source. The airflow direction of the high-pressure air pipe corresponds to the bottom inlet of the guide hood, and the top outlet of the guide hood corresponds to the bottom inlet of the inverted cone hood. The silo cover is also provided with a pressure discharge port and a dust collector is connected to the pressure discharge port.

[0007] The lower part of the mixing silo is fixedly connected to the frame body via a high-pressure bearing frame. The outer wall of the central tube is fixedly connected to the high-pressure bearing frame via multiple sets of radially arranged tension steel ropes. Each set of tension steel ropes includes multiple steel ropes that are radially connected to the outer wall of the central tube. The other end of the steel rope is tightened and connected to the high-pressure bearing frame.

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] like Figure 1-2As shown, this utility model discloses a powder homogenization silo, comprising a mixing silo 1, a discharge pipe 2, a discharge valve 3, a high-pressure air pipe 4, a guide hood 5, an inverted cone hood 6, a central pipe 7, and a high-pressure air source 8. The mixing silo 1 is fixedly installed on the ground via a frame 9. The top of the mixing silo 1 is provided with a silo cover 10, and the silo cover 10 has a material inlet. The bottom of the mixing silo 1 is funnel-shaped, and the discharge pipe 2 is fixedly installed at the bottom end. The discharge valve 3 is installed on the discharge pipe 2. The central pipe 7 is a hollow tubular structure with open top and bottom ends. The top end of the central pipe 7 is connected to the inner top surface of the silo cover 10 via a top fixing member 11. In implementation, the fixing member 11 is fixed to the top end of the central pipe but does not block the top outlet of the central pipe 7. The connection between the top fixing member 11 and the central pipe 7 is also through multiple plates to leave gaps for airflow to carry the powder. The bottom end of the central pipe 7 is fixedly connected to the inverted cone hood 6, and the outer wall of the inverted cone hood 6... Multiple first connecting plates 12 are fixedly connected to the bottom inner wall of the mixing silo 1. The top fixing member 11 and multiple first connecting plates 12 realize the suspension and fixation of the central tube 7 in the center of the mixing silo 1. A guide hood 5 is set directly below the inverted cone cover 6. The guide hood 5 is a hollow cylindrical structure that is narrow at the top and wide at the bottom and open at the top and bottom. The upper part of the outer wall of the guide hood 5 is fixedly connected to the corresponding first connecting plate 12 above it through multiple second connecting plates 13. The lower part of the outer wall of the guide hood 5 is fixedly connected to the outer wall of one end of the high pressure air pipe 4 through multiple third connecting plates 14. The other end of the high pressure air pipe 4 extends out of the mixing silo 1 and is connected to the high pressure air source 8. The airflow direction of the high pressure air pipe 4 corresponds to the bottom inlet of the guide hood 5, and the top outlet of the guide hood 5 corresponds to the bottom inlet of the inverted cone cover. The silo cover 10 is also provided with a pressure discharge port and a dust collector is connected to the pressure discharge port. The dust collector is used to collect and recover the powder carried by the airflow when the pressure is discharged inside the mixing silo 1.

[0015] The lower part of the mixing silo 1 is fixedly connected to the frame 9 via a high-pressure bearing frame 15. The outer wall of the central tube 7 is fixedly connected to the high-pressure bearing frame 15 via multiple radially arranged sets of tension steel ropes 16. Each set of tension steel ropes 16 includes multiple steel ropes radially connected to the outer wall of the central tube 7, and the other end of each steel rope is tensioned and connected to the high-pressure bearing frame 15. In actual installation, the connection method of the tension steel ropes 16 can be adjusted according to the actual situation, such as... Figure 1 The mixing silo 1 shown has a separate design, with a circular upper silo and a funnel-shaped lower silo. The bottom of the circular silo is fixedly and sealed to the high-pressure frame 15, and the top of the funnel-shaped silo is also fixedly and sealed to the high-pressure frame 15, thus forming a complete mixing silo 1. The tension steel cable 16 can be directly fixedly connected to the high-pressure frame 15. Alternatively, depending on installation requirements, a steel cable connecting plate can be installed on the high-pressure frame 15. The steel cable connecting plate penetrates the silo body of the mixing silo 1 and is installed inside it, with the penetration opening sealed with a sealant. The tension steel cable 16 can be connected to the steel cable connecting plate.

[0016] Working process and principle: First, the powder to be homogenized is put into the mixing bin 1 through the inlet on the bin cover 10. The powder forms an angle of repose below the inverted cone 6 (which reduces the thickness of the powder impacted by the airflow to a certain extent, thereby reducing the airflow pressure). The high-pressure air source 8 delivers high-pressure gas to the high-pressure air pipe 4. The high-pressure gas is sprayed at high speed from the high-pressure air pipe 4 into the guide shroud 5, creating a negative pressure outside the guide shroud 5. Using the principle of jet suction, the powder around the bottom of the guide shroud 5 is sucked into the guide shroud 5. The high-pressure gas carrying the powder is sprayed into the inverted cone 6 through the guide shroud 5, and carries a large amount of powder above the guide shroud 5 into the central pipe 7. The powder rises continuously along the central pipe to its top and is then sprayed out. Without subsequent air pressure, the powder is sprayed into the mixing bin 1 in a parabolic manner. In this process, the powder is continuously and efficiently homogenized.
