Description

Technical Field

[0001] This utility model application relates to the field of booster device technology, specifically a booster device for pneumatic conveying of powder. Background Technology

[0002] Powder pneumatic conveying is a technology that uses airflow energy to transport powdery or granular materials in a closed pipeline along the airflow direction. It uses compressed air or gas as power to transport materials from one location to another. It has advantages such as high efficiency, safety, and environmental protection. The basic principle of powder pneumatic conveying is to use airflow as power to transport materials from the starting point to the end point. When the powder material is transported over a long distance, pressure loss and deceleration will occur, and the material fluidization effect will be poor, resulting in a decrease in the powder material conveying speed.

[0003] Most existing booster devices detect a decrease in the powder flow rate inside the pipeline and then increase the speed by supplementing air. However, this method is difficult to use because the powder flow rate is high, and most booster devices are in a normally open state, making it inconvenient to operate according to the real-time powder flow rate, which can easily lead to ineffective operation. Utility Model Content

[0004] To address the problem that existing powder pneumatic conveying booster devices are cumbersome and inconvenient to operate, this utility model provides a powder pneumatic conveying booster device to solve the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A booster device for pneumatic conveying of powder includes a booster pipe and fixed flanges. Fixed flanges are fixed to the outer surfaces of both ends of the booster pipe. A booster box is fixed to the top of the booster pipe. A booster pump is fixedly installed on the top of the booster pipe on the side of the booster box. An air outlet is fixed to the output end of the booster pump and extends into the booster box. Exhaust ports are opened at the bottom of the booster box and the top of the booster pipe. A placement groove is opened inside the booster pipe at the bottom of the exhaust port. A sealing plate is slidably sleeved inside the placement groove. Connecting slide rods are symmetrically fixed to the top of the sealing plate. Both connecting slide rods are slidably sleeved inside the support plate. A spring is sleeved on the connecting slide rod on the bottom surface of each support plate. Both ends of the spring are fixed to the support plate and the connecting slide rod, respectively.

[0007] Furthermore, both the booster tube and the booster box are fixedly installed with air pressure sensors, and the booster box and the booster tube are connected through an exhaust port and a placement slot.

[0008] Furthermore, a limiting plate is fixedly sleeved on the outer surface of the connecting slide rod on the bottom surface of each spring, and the width of both limiting plates is greater than the width of the exhaust port.

[0009] Furthermore, the width of the sealing plate is greater than the width of the exhaust port, the length of the sealing plate is greater than the length of the exhaust port, and a sealing gasket is glued to the top surface of the sealing plate.

[0010] Furthermore, a flow guide baffle is fixed to the side of the sealing plate facing the direction of powder flow, and the flow guide baffle is slidably inserted into the top of the booster tube.

[0011] Furthermore, the exhaust port, placement groove, sealing plate, and flow guide baffle are all configured as arc shapes to cooperate with the booster tube, and the height of the flow guide baffle is greater than the distance between the sealing plate and the bottom surface of the limiting connecting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by utilizing the air pressure difference between the booster box and the booster tube, the sealing plate can be moved under the action of the air pressure difference during conveying, and the exhaust port can be opened to replenish air and increase speed. This solves the problem that the existing booster device for powder pneumatic conveying is relatively cumbersome and inconvenient to operate, improves the practicality of the booster device, and ensures the boosting effect.

[0014] 2. In this utility model, the side guide plate is used to block and guide the flow, preventing the powder from entering the booster box while ensuring that the gas discharged from the booster box can flow along the conveying direction, thereby further improving the boosting effect. In conjunction with the air pressure sensor inside the booster box and booster tube, the conveying speed of the conveying system is guaranteed. Attached Figure Description

[0020] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Reference Figure 1 , Figure 2 and Figure 3 A booster device for pneumatic conveying of powder includes a booster pipe 1 and a fixed flange 2. The fixed flange 2 is fixed to the outer surface of both ends of the booster pipe 1. Pressure sensors 14 are fixedly installed inside both the booster pipe 1 and the booster box 3. The booster box 3 is connected to the booster pipe 1 through an exhaust port 6 and a placement groove 7. The booster box 3 is fixed to the top of the booster pipe 1. A booster pump 4 is fixedly installed on the top of the booster pipe 1 on the side of the booster box 3. An air outlet 5 is fixed to the output end of the booster pump 4, extending into the interior of the booster box 3. Openings are located at the bottom of the booster box 3 and the top of the booster pipe 1. There is an exhaust port 6. The booster pipe 1 at the bottom of the exhaust port 6 has a placement groove 7. A sealing plate 8 is slidably sleeved inside the placement groove 7. A connecting slide rod 9 is symmetrically fixed on the top of the sealing plate 8. Both connecting slide rods 9 are slidably sleeved inside the support plate 10. A spring 11 is sleeved on the connecting slide rod 9 on the bottom surface of each support plate 10. Both ends of the spring 11 are fixed to the support plate 10 and the connecting slide rod 9 respectively. A limiting plate 15 is fixedly sleeved on the outer surface of the connecting slide rod 9 on the bottom surface of each spring 11. The width of the two limiting plates 15 is greater than the width of the exhaust port 6.

[0022] Specifically, during use, the booster pump 4 operates to control the internal air pressure of the booster box 3. When the powder flow rate inside the booster tube 1 meets the standard, the air pressure inside the booster box 3 and the booster tube 1 is the same. Under the push of the spring 11, the sealing plate 8 drives the sealing gasket 12 to abut against the top of the placement slot 7 to seal the exhaust port 6. When the powder flow rate inside the booster tube 1 decreases, the air pressure sensor 14 detects that the air pressure inside the booster tube 1 is greater than the air pressure inside the booster box 3. Then, the booster pump 4 operates to inflate the booster box 3, increasing the air pressure inside the booster box 3. Under the push of the air pressure, the sealing plate 8 moves down, opening the exhaust port 6 and the placement slot 7. Airflow enters the booster tube 1 to boost the powder. When the air pressure inside the booster tube 1 is within the standard range, the booster pump 4 operates, making the air pressure inside the booster box 3 equal to that inside the booster tube 1. Under the pull of the spring 11, the sealing plate 8 abuts against the inside of the placement slot 7, closing the exhaust port 6.

[0023] As an optimization solution, such as Figure 2 and Figure 3 As shown, the width of the sealing plate 8 is greater than the width of the exhaust port 6, and the length of the sealing plate 8 is greater than the length of the exhaust port 6. A sealing gasket 12 is glued to the top surface of the sealing plate 8. A flow guide baffle 13 is fixed to the side of the sealing plate 8 facing the direction of powder flow. The flow guide baffle 13 is slidably inserted into the top of the booster tube 1. The exhaust port 6, the placement groove 7, the sealing plate 8 and the flow guide baffle 13 are all set to be arc-shaped to cooperate with the booster tube 1. The height of the flow guide baffle 13 is greater than the distance between the sealing plate 8 and the bottom surface of the limiting connecting plate 15.

[0024] Specifically, after the sealing plate 8 moves down to open the exhaust port 6 and the placement slot 7, the powder is prevented from directly entering the booster box 3 by the flow guide baffle 13. At the same time, under the obstruction and guidance of the flow guide baffle 13, the pressurized airflow can flow along the direction of powder flow, thereby ensuring the pressurization effect.
