Description

Technical Field

[0001] The powder quality homogenization bin of the present invention belongs to the technical field of chemical production, and in particular relates to the quality homogenization of powder finished products. Background Art

[0002] In production, chemical companies not only have certain requirements for product quality, but 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 sensitive to temperature requirements during use. Therefore, the quality of gypsum powder plays a decisive role in the initial setting time. If the quality of gypsum powder products of the same specifications is inconsistent, it will lead to deviations in the use effect.

[0004] Therefore, before the powdered materials leave the factory, the products of the same specifications will be mixed and homogenized, so that the quality of the products of the same specifications is highly consistent. The current method is generally to send the materials into the bin and mix them by stirring, but this homogenization method requires a stirring shaft and a high-power motor, which consumes a lot of energy. In addition, during the stirring process, some areas in the bin cannot be stirred, resulting in many dead corners, which affects the homogenization quality. Summary of the invention

[0005] In order to solve one of the above technical defects, the present invention provides a powder quality homogenization bin with high homogenization quality, high efficiency, low energy consumption and low transformation cost.

The upper part of the outer wall of the guide hood is fixedly connected to the corresponding first connecting plates above through multiple second connecting plates, and 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 through multiple third connecting plates.

DETAILED DESCRIPTION

[0011] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0012] like Figure 1-2As shown, the powder mass homogenization bin of the present invention comprises a mixing bin 1, a discharge pipe 2, a discharge valve 3, a high-pressure air pipe 4, a guide cover 5, an inverted cone cover 6, a central tube 7 and a high-pressure air source 8. The mixing bin 1 is fixedly installed on the ground through a frame 9. A bin cover 10 is provided at the top of the mixing bin 1 and an inlet is provided on the bin cover 10. The bottom of the mixing bin 1 is funnel-shaped and a discharge pipe 2 is fixedly installed at the bottom. A discharge valve 3 is installed on the discharge pipe 2. The central tube 7 is a hollow tubular structure with open upper and lower ends. The top of the tube body of the central tube 7 is connected to the inner top surface of the bin cover 10 through a top fixing member 11. In practice, the fixing member 11 is fixed to the top of the central tube and cannot block the top outlet of the central tube 7. The connection between the top fixing member 11 and the central tube 7 is also connected through multiple plates to leave a gap for airflow to carry powder. The bottom end of the central tube 7 is fixedly connected to an inverted cone cover 6. The outer wall of the inverted cone cover 6 is connected through Multiple first connecting plates 12 are fixedly connected to the inner wall at the bottom of the mixing bin 1, and the top fixing piece 11 and the multiple first connecting plates 12 realize the suspended fixation of the central tube 7 in the center of the mixing bin 1. A guide cover 5 is arranged directly below the inverted cone cover 6. The guide cover 5 is a hollow cylinder structure which 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 cover 5 is fixedly connected to the corresponding first connecting plate 12 above through multiple second connecting plates 13, and the lower part of the outer wall of the guide cover 5 is fixedly connected to the outer wall of the pipe opening at 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 bin 1 and is connected to the high-pressure air source 8. The airflow ejection direction of the high-pressure air pipe 4 corresponds to the bottom inlet of the guide cover 5, and the top outlet of the guide cover 5 corresponds to the bottom inlet of the inverted cone cover. A pressure discharge port is also arranged on the bin cover 10 and a dust collector is connected to the pressure discharge port. The dust collector is used to collect and recycle the powder carried by the airflow when the pressure is discharged inside the mixing bin 1.

[0013] The lower part of the mixing bin 1 is fixedly connected to the frame 9 through a high pressure frame 15, and the outer wall of the central tube 7 is fixedly connected to the high pressure frame 15 through multiple groups of tensioning steel ropes 16 arranged radially. Each group of tensioning steel ropes 16 includes multiple steel ropes radially connected to the outer wall of the central tube 7. The other end of the steel rope is tightened and connected to the high pressure frame 15. In actual installation, the connection method of the tensioning steel ropes 16 can be adjusted according to actual conditions, such as Figure 1 The mixing silo 1 shown has a split design of the circular silo body at the top and the funnel-shaped silo body at the bottom. The bottom end of the circular silo body is fixedly and sealedly connected to the high pressure frame 15, and the upper end of the funnel-shaped silo body is fixedly and sealedly connected to the high pressure frame 15, thereby forming a complete mixing silo 1. The tensioning steel rope 16 can be directly fixedly connected to the high pressure frame 15. A steel rope connecting plate can also be provided on the high pressure frame 15 according to installation requirements. The steel rope connecting plate penetrates the silo body of the mixing silo 1 and is arranged inside the silo and is sealed at the penetration port with a seal. The tensioning steel rope 16 can be connected to the steel rope connecting plate.

[0014] Working process and principle: first, the powder material of the required homogenization mass is put into the mixing bin 1 through the feeding port on the bin cover 10, and the powder material forms a repose angle under the inverted cone cover 6 (to a certain extent, the thickness of the powder material impacted by the airflow is reduced, thereby reducing the airflow pressure), and the high-pressure gas source 8 delivers high-pressure gas to the high-pressure gas pipe 4, and the high-pressure gas is sprayed from the high-pressure gas pipe 4 to the air guide cover 5 at a high speed, so that a negative pressure is formed outside the air guide cover 5, and the powder material around the bottom of the air guide cover 5 is sucked into the air guide cover 5 by utilizing the injection and suction principle, and the high-pressure gas carrying the powder material is sprayed into the inverted cone cover 6 through the air guide cover 5, and carries a large amount of powder material above the air guide cover 5 into the central tube 7, and continuously rises along the central tube to its top and then sprays out. In the absence of subsequent air pressure, the powder material is parabolically sprinkled into the mixing bin 1, and in this process, uninterrupted and efficient homogenization of the powder material is achieved.
