Description

Technical Field

[0001] This utility model relates to the field of pneumatic conveying technology, specifically an energy-saving operation optimization device for a pneumatic ash removal system. Background Technology

[0002] Pneumatic conveying devices are used in power plants and cement plants for conveying ash materials. When in use, the material enters the silo, and then compressed gas is introduced into the silo. The compression of the compressed gas forces the material inside the silo into the pipeline for conveying.

[0003] In existing silos, materials adhere to the inner wall due to adhesion and compression during use. When performing soot blowing, compressed gas has difficulty squeezing and conveying the adhered materials. An annular blowpipe is installed at the top of the silo to blow the inner wall. However, the annular blowpipe is usually fixed, so the jet angle of the nozzle is fixed and it cannot dynamically blow the inner wall of the silo. The blowing uniformity is low during use. In order to compensate for the uniformity, the air supply volume needs to be increased, resulting in a great waste of compressed air.

[0004] To address these issues, we have developed an energy-saving operation optimization device for pneumatic ash removal systems. Utility Model Content

[0005] 1) Technical problems to be solved

[0006] This utility model proposes an energy-saving operation optimization device for a pneumatic ash removal system. Through the cooperation between the air inlet pipe, the drive mechanism and the solenoid valve, the problem of not being able to dynamically purge the inner wall of the silo is solved.

[0007] (ii) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving operation optimization device for a pneumatic ash removal system, comprising a material pump, wherein an air inlet pipe 1 and an air inlet pipe 2 are respectively connected inside the material pump, and control valves are installed on the outside of both the air inlet pipe 1 and the air inlet pipe 2.

[0009] The feed pump has a detachable fixed ring inside. Multiple sets of mounting cylinders are fixedly installed on the inner wall of the fixed ring. A sealing cavity is provided inside the mounting cylinder. A drive mechanism is installed inside the sealing cavity. An annular tube is installed outside the drive mechanism. Multiple sets of nozzles are connected inside the annular tube.

[0010] The fixed ring has a connecting pipe inside, a solenoid valve is connected to the outside of the connecting pipe, and a flexible hose is connected inside the solenoid valve.

[0011] Furthermore, the inlets of the first and second air intake pipes are connected to each other, and the first and second air intake pipes are controlled to open and close by multiple sets of control valves.

[0012] Furthermore, the upper and lower ends of the material pump are respectively connected to the inlet pipe and the outlet pipe, and multiple sets of the mounting cylinders are arranged in a ring array inside the fixed ring.

[0013] Furthermore, the driving mechanism includes a driving block, the outer surface of which is slidably connected to the inner wall of the sealing cavity, a U-shaped plate is fixedly installed on the outer surface of the driving block, and the outer surface of the annular tube is fixedly installed at the lower end of the U-shaped plate.

[0014] Furthermore, a spring is fixedly installed on the outer surface of the drive block, and the other end of the spring is fixedly installed on the inner wall of the sealing cavity.

[0015] Furthermore, one end of the second intake pipe is connected to the interior of the solenoid valve, one end of the connecting pipe is connected to the interior of the sealing cavity, and one end of the flexible hose is connected to one end of the annular pipe.

[0017] (iii) Beneficial effects:

[0018] Compared with existing technologies, this pneumatic ash removal system energy-saving operation optimization device has the following beneficial effects:

[0019] I. The energy-saving operation optimization device of this pneumatic ash removal system, through the cooperation between the air inlet pipe, the drive mechanism and the solenoid valve, controls the air flow between the annular pipe and the sealed cavity during use, and controls the regular flow of gas in the sealed cavity. At this time, the internal drive mechanism can control the annular pipe to swing in a circular motion. Under the swing of the nozzle, the inside of the hopper can be dynamically purged, improving the purging effect, reducing the air waste caused by unevenness, and realizing the function of dynamic purging inside the hopper, which is conducive to improving the uniformity of purging.

[0020] II. The energy-saving operation optimization device of this pneumatic ash removal system, by setting up components such as springs and control valves, uses multiple sets of control valves to control the flow of gas inside the first and second air inlets. For example, when conveying materials, the second air inlet is closed, and when purging, the first air inlet is closed. The control valves control the amount of gas inside the pipes. When the pressure inside the sealed cavity increases, the drive block moves slowly. Under the control of the solenoid valve, the gas inside the connecting pipe is controlled to open or close. When the internal gas is disconnected, the spring can pull the drive block to reset, realizing the function of controlling the dynamic movement of the drive block. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-4 As shown, this utility model provides a technical solution: an energy-saving operation optimization device for a pneumatic ash removal system, including a material pump 1, with an inlet pipe 14 and an outlet pipe 15 respectively connected to the upper and lower ends of the material pump 1. The material pump 1 and the inlet pipe 14 are connected to an external inlet valve to realize gravity conveying of external materials. A balance pipe and a balance valve are also installed inside the material pump 1 to balance the internal air pressure. An outlet valve is installed outside the outlet pipe 15 to control the on / off state.

[0029] The material pump 1 is internally connected to an air inlet pipe 2 and an air inlet pipe 3. Both air inlet pipes 2 and 3 are equipped with control valves 4. The ports of air inlet pipes 2 and 3 are interconnected. The air inlet pipes 2 and 3 are controlled by multiple sets of control valves 4. When starting up, the material first enters the material pump 1. Then, the gas inside air inlet pipe 2 enters the hopper and compresses the material inside. The material can be discharged through the discharge pipe 15. The control valves 4 control the flow of gas in air inlet pipes 2 and 3, so the gas in air inlet pipes 2 and 3 will not flow simultaneously.

[0030] The material pump 1 has a detachable fixed ring 5 inside. Multiple sets of mounting cylinders 6 are fixedly installed on the inner wall of the fixed ring 5. The mounting cylinders 6 have a sealing cavity 7 inside. The multiple sets of mounting cylinders 6 are arranged in a ring array inside the fixed ring 5. The fixed ring 5 is fixed to the inner top wall of the hopper by multiple sets of fixing bolts. The multiple sets of mounting cylinders 6 are arranged in a ring and have an opening at one end. When the gas inside the sealing cavity 7 flows, it will slowly discharge through the opening at one end.

[0031] A drive mechanism 8 is installed inside the sealed cavity 7, and an annular tube 9 is installed outside the drive mechanism 8. Multiple sets of nozzles 10 are connected inside the annular tube 9. The multiple sets of nozzles 10 are arranged in a ring outside the annular tube 9. The nozzles 10 and the annular tube 9 are arranged at an angle. When the gas flows inside the sealed cavity 7, the drive mechanism 8 can control the annular tube 9 to swing. At this time, the nozzles 10 inside the annular tube 9 blow away the material attached to the inner wall of the hopper. By using the regular swing of the annular tube 9 to control the nozzles 10 to perform dynamic blowing, the blowing effect and the uniformity of blowing can be improved.

[0032] The fixed ring 5 is connected to a connecting pipe 11. One end of the connecting pipe 11 is connected to the inside of the sealing cavity 7. The outside of the connecting pipe 11 is connected to a solenoid valve 12. One end of the air inlet pipe 3 is connected to the inside of the solenoid valve 12. The inside of the solenoid valve 12 is connected to a hose 13. One end of the hose 13 is connected to one end of the annular pipe 9. The solenoid valve 12 is a multi-port valve. After the gas enters from one end, it can enter the inside of the connecting pipe 11 and the hose 13 respectively. When the gas enters the inside of the annular pipe 9, it is blown out through the nozzle. When the gas enters the inside of the connecting pipe 11, it enters the inside of the sealing cavity 7.

[0033] The drive mechanism 8 includes a drive block 801. The outer surface of the drive block 801 is slidably connected to the inner wall of the sealing cavity 7. A U-shaped plate 802 is fixedly installed on the outer surface of the drive block 801. The outer surface of the annular tube 9 is fixedly installed at the lower end of the U-shaped plate 802. A spring 803 is fixedly installed on the outer surface of the drive block 801. The other end of the spring 803 is fixedly installed to the inner wall of the sealing cavity 7. The gas entering the sealing cavity 7 can push the drive block 801 with the sealing strip to move. At this time, the drive block 801 pushes the U-shaped plate 802 to move, further controlling the swing of the annular tube 9. A pressure relief valve can also be installed inside the connecting pipe 11. When no gas enters the connecting pipe 11, one end is closed. At this time, the pressure relief valve is activated. Under the push of the spring 803, the drive block 801 is reset, realizing the automatic reset of the annular tube 9.

[0034] Working principle: During cleaning, gas enters the solenoid valve 12 through the air inlet pipe 2 3. The solenoid valve 12 can control the flow of gas in the hose 13 and connecting pipe 11. The gas enters the annular tube 9 and is ejected through the nozzle 10. The gas enters the sealing cavity 7 and pushes the drive block 801 to move. At this time, the drive block 801 can control the rotation of the annular tube 9. When no gas enters the hose 13, the gas in the sealing cavity 7 is discharged. The spring 803 pulls the drive block 801 to reset. At this time, the annular tube 9 is reset. The flow of gas in the sealing cavity 7 can control the annular tube 9 to swing cyclically, realizing dynamic purging of the inner wall of the hopper.
