Description

Technical Field

[0001] The invention relates to the field of aerospace furnace gasification slag removal, and in particular to a pipeline vibration processing device for aerospace furnace gasification slag locking bucket. Background Art

[0002] Coal gasification refers to the process in which solid fuels such as coal, coke, and semi-coke react with gasifying agents under high temperature, normal pressure, or pressurized conditions to convert them into gas products and a small amount of residue.

[0003] The slag lock bucket water filling valve in the aerospace coal gasification slag flushing link has a large valve diameter and a large amount of air in and out of the gas-controlled quick exhaust valve. The strong vibration during the valve switching process causes the pipeline to shake violently. Currently, flexible pipe soft connection is used to reduce pipeline vibration and reduce the impact of pipeline on equipment, but the cost is high and the construction is difficult. Although this method reduces the impact on equipment, the vibration of the valve itself is still not alleviated. This vibration also causes the connection between the pipeline and the flexible pipe to have the risk of loosening and leakage, and makes the connection between the valve's actuator and the valve body loose. In this way, the intensity of daily inspections and the increase of maintenance costs are increased.

[0004] Therefore, it is necessary to provide a pipeline vibration processing device for aerospace furnace gasification slag lock bucket to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0037] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0038] Please refer to Figure 1 ,in, Figure 1The schematic diagram of the structure of the first embodiment of the pipeline vibration processing device for the aerospace furnace gasification slag lock bucket provided by the present invention. The pipeline vibration processing device for the aerospace furnace gasification slag lock bucket comprises: a first pressure reducing valve 1 and a cylinder 8;

[0039] A first air-controlled valve 6, the first air-controlled valve 6 being connected to one end of the first pressure-reducing valve 1 through a main air pipeline;

[0040] A second air-controlled valve 7, wherein the second air-controlled valve 7 is connected to one end of the main air pipeline through a branch line, and the exhaust ends of the first air-controlled valve 6 and the second air-controlled valve 7 are respectively connected to a first flow-limiting damper 4 and a second flow-limiting damper 5, and one end of the first air-controlled valve 6 and the second air-controlled valve 7 are both connected to two sides of the cylinder 8 through a connecting pipeline;

[0041] The second pressure reducing valve 2 is connected to the main air pipeline through a control air pipeline, and a solenoid valve 3 is arranged on the control air pipeline. One end of the control air pipeline is connected to the first air control valve 6 and the second air control valve 7 through two branch pipes.

[0042] The first air control valve 6 is communicated with the side of the non-axial extension end of the cylinder 8 housing, and the second air control valve 7 is communicated with the side of the axial extension end of the cylinder 8 housing.

[0043] The working principle of the pipeline vibration treatment device for the aerospace furnace gasification slag lock bucket provided by the present invention is as follows:

[0044] The control gas passes through the second pressure reducing valve 2 and enters the solenoid valve 3, and then enters the first gas control valve 6 and the second gas control valve 7;

[0045] The main gas enters the air control valve through the first pressure reducing valve 1. When the solenoid valve 3 is energized, the first air control valve 6 is activated, and the main gas enters the non-axial extension end of the cylinder 8 through the first air control valve 6.

[0046] At the same time, the second air control valve 7 is actuated, and the main gas is stopped through the second air control valve 7. At this time, the shaft extension end of the cylinder 8 is connected with the exhaust end of the second air control valve 7 for exhaust;

[0047] When the electromagnetic valve 3 is powered off, the air control valve 67 is restored under the action of the spring, and the non-axial extension end of the cylinder 8 is connected to the exhaust end of the first air control valve 6 for exhaust, while the axial extension end is connected to the intake end of the second air control valve 7 for intake. That is, when the electromagnetic valve 3 is powered on, the piston of the cylinder 8 is pushed out, and vice versa, when the electromagnetic valve 3 is powered off, the piston of the cylinder 8 is pushed in.

[0048] By arranging the first flow limiting dampers 4 and 5 to control the exhaust flow of the cylinder 8, the impact during the opening or closing process of the valve can be well controlled.

[0049] Compared with the related art, the pipeline vibration treatment device for aerospace furnace gasification slag lock bucket provided by the present invention has the following beneficial effects:

[0050] By connecting the first flow limiting damper 4 and the second flow limiting damper 5 to the exhaust ports of the first air-controlled valve 6 and the second air-controlled valve 7 respectively, the exhaust flow rates of the two air-controlled valves can be adjusted respectively, which greatly reduces the severe vibration of the actuator caused by the excessive pressure difference before and after the cylinder piston due to the discharge of excessive air volume when opening or closing the valve during the switching process.

[0055] An air inlet 13 is formed at the top of the housing 11 , and an air outlet 14 is formed at the bottom of the housing 11 .

[0056] There are multiple exhaust holes 14 , no less than three, and a pipe connector is provided on the top of the shell 11 and is located outside the air inlet 13 .

[0058] The penetration point of the push rod 93 and the installation cylinder 91 is clearance-matched, and the edge of the first piston block 92 and the interior of the installation cylinder 91 are both smoothly arranged.

[0059] The top and bottom of the first piston block 92 are fixedly connected to the inner wall of the mounting tube 91 via a first sealing member 95 , and a rubber sleeve is provided on the surface of the blocking ball 94 .

[0061] The retraction assembly 10 includes a retraction cylinder 101 and a limit bolt 108. The retraction cylinder 101 is internally slidably connected with a second piston block 102.

The two ends of the first seal 95 and the second seal 109 are respectively inserted into the two annular placement grooves, and are filled and fixed with glue for sealing. The length of the first seal 95 is greater than the length of the push rod 93 located at the outer part of the mounting cylinder 91 when an elastic member 104 is in a normal state. The material of the first seal 95 and the second seal 109 can be rubber, silicone or other soft sealing materials. The mounting cylinder 91 is located below the first piston block 92 and is connected to the retraction cylinder 101 through the connecting pipe 16 and is located below the second piston block 102. The two seals are filled with transmission liquid, which can be hydraulic oil or replaced by gas.

[0063] A fixed block 103 is fixedly installed on the top of the retraction cylinder 101, a first elastic member 104 is arranged at the bottom of the fixed block 103, a limiting block 107 is fixedly connected to one side of the fixed block 103, an annular protrusion 105 is arranged at the bottom of the fixed block 103, an annular groove 106 is opened on the top of the retraction cylinder 101, and a limiting groove 110 is opened on one side of the surface of the limiting bolt 108.

[0064] The annular groove 106 is adapted to the size of the annular protrusion 105, and a rubber block is sleeved on the surface of the annular protrusion 105 to improve the stability and sealing of the installation. A limiting hole is opened on the limit block 107, and a strip groove is opened in the middle of the bottom of the fixing block 103, and one end of the first elastic member 104 is inserted into the strip groove.

[0065] An anti-loosening component 12 is arranged on the top of the fixing block 103, and the anti-loosening component 12 includes a mounting block 121, a fixing hole 122 is opened on the mounting block 121, the top of the inner surface of the fixing hole 122 is connected to a mounting groove, a positioning block 123 is arranged inside the mounting groove, and a connecting rod 124 is fixedly connected to the top of the positioning block 123, and the top end of the connecting rod 124 extends to the outside of the mounting block 121 through a through hole 128.

[0066] The through hole 128 and the connecting rod 124 are clearance-matched, the positioning block 123 is a cylindrical block, and the limiting groove 110 and the positioning block 123 are adapted.

[0067] The top end of the connecting rod 124 is fixedly connected with a pressing block 126, the surface of the connecting rod 124 is sleeved with a second elastic member 125 located between the pressing block 126 and the mounting block 121, the surface of the connecting rod 124 is fixedly connected with a stopper 127, one side of the inner surface of the mounting groove is connected with a card slot, and one side of the inner surface of the through hole 128 is connected with a rectangular hole 129.

[0068] The slot is connected to the through hole 128 , and the cross-sectional area of ​​the slot is the same as that of the stopper 127 .

[0069] Threaded holes 15 are formed on both sides of the housing 11 , and one end of the limiting bolt 108 passes through the limiting block 107 and the fixing hole 122 in sequence and is threadedly connected to the threaded hole 15 .

[0070] One end of the surface of the limiting bolt 108 is provided with an external thread matched with the threaded hole 15 .

[0071] The original flow-limiting damper uses a spring to hold the blocking ball 94 in place, but instead uses hydraulic oil in combination with a first elastic member. Two first elastic members are located on both sides of the damper, making it easy to replace the spring. The spring is directly used to hold the blocking ball 94. The spring is easily deformed after long-term use, and is difficult to replace, or is directly discarded.

[0072] The method of combining the hydraulic oil with the first elastic member improves the damping effect and prolongs the service life. When the first elastic member is deformed, the block 127 can be moved out of the slot by pressing the block 126 downward, and then the pressing block 126 is rotated to make the block 127 correspond to the rectangular hole 129. At this time, the second elastic member 125 presses the pressing block 126 upward to make the positioning block 123 move out of the limiting slot 110.

[0073] Then rotate the limit bolt 108 to remove it, then you can directly remove the fixing block 103, remove the first elastic member 104, replace the new first elastic member 104, and then insert the end of the new first elastic member 104 into the strip groove at the bottom of the fixing block 103, and then prevent it from entering the retraction cylinder 101, so that the annular protrusion 105 at the bottom of the fixing block 103 is inserted into the annular groove 106, and then one end of the limit bolt 108 is passed through the limit block 107 and the fixing hole 122 in sequence and is threadedly connected to the threaded hole 15 until it can no longer rotate;

[0074] At this time, the limiting groove 110 on one side of the surface of the limiting bolt 108 corresponds to the position of the installation groove inside the installation block 121. At this time, the pressing block is pressed downward to make the positioning block 123 enter the limiting groove 110 and compress the second elastic member 125 to limit the limiting bolt 108. At this time, the stopper 127 enters the installation groove through the rectangular hole 129. At this time, the pressing block 126 is rotated 180 degrees, and the stopper 127 corresponds to the position of the card slot. The pressing block 126 is released, and the stopper 127 enters the card slot through the action of the second elastic member 125. At this time, the second elastic member 125 is still in a compressed state, and the limiting bolt 108 can be prevented from loosening by the anti-loosening component 12;

[0075] The replacement operation of the first elastic member 104 is simple and convenient, which improves the replacement efficiency and is easy to use. When the first elastic member 104 is deformed, it can be replaced without replacing the entire damper, which saves costs.

[0076] By setting the first seal 95 and the second seal 109 to be straight-cylindrical, and the length of the seal is greater than the length of the push rod 93 located at the outer part of the mounting tube 91 when an elastic member 104 is in a normal state, and by using a straight-cylindrical seal to replace the traditional sealing ring, the wear of the seal is avoided and the service life of the seal is increased.
