Description

Technical Field

[0001] The invention relates to the technical field of powder material conveying, and in particular to a pneumatic conveying device with a conical cap for regulating material discharge. Background Art

[0002] In the rubber refining process of rubber factories, a large number of different types of powders are used. Generally, pneumatic conveying is used to transport the powders in the tank truck to the rubber refining workshop. In the pneumatic conveying of powders, the powders are first discharged from the tank truck, and the suction of the negative pressure fan is used to send the powders to the storage tank through the conveying pipeline. In order to ensure the continuous and stable discharge of the powders when they are discharged from the tank truck and improve the conveying efficiency, it is required to be able to flexibly adjust the discharge amount of the powders according to the characteristics of the powders, and to be able to choose between conveying in one pipeline or conveying in two pipelines at the same time. The current practice is usually to use a structure in which the discharge pipe is directly connected to the discharge interface of the tank truck. Since the discharge amount of the powders cannot be adjusted, the flow of the powders cannot be controlled, and the powders often have problems in the process of falling, such as either too little discharge, which reduces the conveying capacity and increases energy consumption, or too much discharge, which causes the pipeline to be blocked and unable to be transported. A pneumatic conveying device with a conical cap for adjusting the discharge of materials is proposed. The position of the conical cap in the discharge pipe can be adjusted by rotating the adjusting screw, so as to control the discharge amount of different types of powder materials. A nylon plate is arranged at the bottom of the conical cap to improve the sealing effect between the conical cap and the inner wall of the discharge pipe. Two discharge ports are adopted to flexibly select the destination of the conveyed powder, thereby realizing the adjustable discharge amount of powder materials and the flexible selection of the destination of the conveyed powder materials during pneumatic conveying, improving the stability and work efficiency of conveying, and reducing energy consumption. Summary of the invention

[0003] The purpose of the present invention is to provide a pneumatic conveying device with a conical cap for adjusting the discharge of powder, which meets the requirements that the discharge amount of powder can be adjusted and can be selected between conveying in one pipeline or conveying in two pipelines at the same time.

[0005] Furthermore, the central axis of the drop pipe is at a 90° angle to the central axis of the discharge pipe. There are two discharge pipes, and their central axes are at a 90° angle. The central axis of the air inlet pipe is in the same plane as the central axes of the two discharge pipes, and the central axis of the air inlet pipe is at a 135° angle to the central axis of the adjacent discharge pipe.

The air inlet pipe 2 and the discharge pipe 13 are welded on the discharge pipe 1, the air inlet pipe 2 is connected to the air volume regulating valve 3, the air volume regulating valve 3 is connected to the filter screen 4, the discharge pipe 13 is connected to the gate valve 14, the gate valve 14 is connected to the quick connector 15, the conical cap 5 and the nylon plate 6 are fixedly connected by the adjusting screw 8 and the upper locking nut 7, the adjusting screw 8 passes through the flange 12 by thread and is locked by the lower locking nut 9, the flange 12 is connected to the discharge pipe 1 by the connecting bolt 10 and is sealed by the rubber gasket 11, and the position of the conical cap 5 in the discharge pipe 1 is adjusted by the adjusting screw 8. The central axis of the blanking tube 1 is at a 90° angle to the central axis of the discharge tube 13. There are two discharge tubes 13, and their central axes are at a 90° angle. The central axis of the air inlet pipe 2 is in the same plane as the central axes of the two discharge tubes 13, and the central axis of the air inlet pipe 2 is at a 135° angle to the central axis of the adjacent discharge tube 13. The conical cap 5 is a right cone, and its bottom center is tapped. The nylon plate 6 is a circular plate with a hole in the center. The bottom circle diameter of the conical cap 5 is smaller than the outer circle diameter of the nylon plate 6, and the outer circle of the nylon plate 6 forms a seal with the inner wall of the blanking tube 1.

[0014] Combination Figure 1 and Figure 2As shown, the conical cap 5 has two extreme points, the highest and the lowest, in the discharge pipe 1. The highest point is at the position where the bottom circle of the conical cap 5 and the lower part of the discharge pipe 13 intersect, and the lowest point is at the position where the upper locking nut 7 and the surface of the flange 12 are in contact. The conical cap 5 can be adjusted between these two extreme points by the adjusting screw 8. The position of the conical cap 5 in the discharge pipe 1, that is, the discharge amount of the powder, can be adjusted before the start of pneumatic conveying, or it can be adjusted during the pneumatic conveying. When adjusting, first loosen the lower locking nut 9, and use a wrench to turn the adjusting screw 8. The height value of the conical cap 5 moving up or down can be displayed according to the number of turns. When the conical cap 5 moves up, the actual discharge amount decreases. On the contrary, when the conical cap 5 moves down, the actual discharge amount increases. After the position of the conical cap 5 is determined, tighten the lower locking nut 9. The nylon plate 6 at the bottom of the conical cap 5 can prevent the powder from leaking to the lower part of the discharge pipe 1. The upper locking nut 7 is used to lock the conical cap 5, the nylon plate 6 and the adjusting screw 8, and the rubber gasket 11 is used to connect the bolt 10 to seal the blanking pipe 1 and the flange 12.

The air enters the blanking pipe 1 through the filter 4 and the air volume regulating valve 3, and mixes with the powder entering the blanking pipe 1. The powder is accompanied by air through the discharge pipe 13, the gate valve 14 and the quick connector 15 into the pneumatic conveying pipeline, and finally reaches the storage tank for storage. After the conveying is completed, the fan is turned off, and the air volume regulating valve 3 and the gate valve 14 are closed. When it is necessary for two discharge pipes 13 to discharge materials at the same time, that is, to feed materials to two pneumatic conveying pipelines at the same time, the two gate valves 14 are opened at the same time, the corresponding quick connectors 15 are connected to the conveying pipelines, the fan connected to the end of the conveying system is turned on, and the opening of the air volume regulating valve 3 is adjusted. The air enters the drop pipe 1 through the filter 4 and the air volume regulating valve 3, and mixes with the powder entering the drop pipe 1. The powder is accompanied by air through the two discharge pipes 13, the gate valve 15 and the quick connector 15 and enters the two pneumatic conveying pipelines at the same time, and finally reaches their respective storage tanks for storage. After the conveying is completed, the fan is turned off, and the air volume regulating valve 3 and the gate valve 14 are closed. Repeating the above actions can realize the continuous and stable conveying of powder and the flexible selection of the powder destination, thereby simplifying the conveying structure, reducing the conveying energy consumption, and improving the work efficiency.
