Description

Technical Field

[0001] This utility model relates to the field of gas separator technology, and in particular to a dual-speed venting control device for a gas separator. Background Technology

[0002] Gas spacers are used in mining operations and construction earthwork. When in use, the gas spacer is positioned inside the blast hole, and explosives are loaded into the blast hole above the gas spacer for detonation, which can achieve good blasting effect and efficiency. When using the gas spacer, the gas inside the gas spacer needs to be released through a gas release control device.

[0003] Existing gas compartment venting control devices mostly use single-speed venting valves. Because the time from initial venting to expansion and positioning into the rupture hole is relatively fixed for single-speed venting gas compartments, they can only be adapted to rupture holes of a single hole depth, resulting in poor applicability. Therefore, a dual-speed venting control device for gas compartments is provided. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the above-mentioned technology and provide a dual-speed venting control device for a gas separator.

The top of the gas tank is fixedly connected to an outlet pipe, and the inner side of the outlet pipe is fixedly connected to a pressing device. The outer side of the pressing device is movably connected to a connecting frame, and the top of the connecting frame is fixedly connected to a sealing block. A sealing plate is fixedly connected between adjacent connecting frames. The connecting frame includes a frame body movably connected to the outer side of the pressing device. The lower part of the frame body is provided with a lifting hole, and a locking block is movably connected inside the frame body. A return spring is fixedly connected between the frame body and the locking block.

[0006] Preferably, the gas cylinder includes a cylinder body, the top of which has an opening.

[0007] Preferably, the vent pipe includes a pipe body fixedly connected to the top of the tank. The top of the pipe body is provided with a through hole, the middle of the inside of the pipe body is provided with a pipe hole, the inside of the pipe body is provided with a plate groove, the outside of the pipe body is provided with a lifting groove, a clamping groove and a placement groove, and both the outside and the inside of the pipe body are provided with vent holes.

[0008] Preferably, the sealing block includes an upper block fixedly connected to the top of the frame, a lower block fixedly connected to the lower part of the upper block, a sealing sleeve fixedly connected to the outer side of the lower block, and a first sealing gasket fixedly connected to the lower part of the lower block.

[0011] This utility model provides a dual-speed venting control device for a gas separator, which has the following beneficial effects:

[0012] This invention, by incorporating a sealing block, a pressing device, a sealing plate, and a connecting frame, facilitates the dual-speed discharge of gas from the gas tank. Pulling the upper block upwards causes the lower block to move the first sealing gasket away from the tank body, opening the opening and allowing gas to enter between the tank body and the first sealing gasket. Simultaneously, this causes the frame and plate to rise, aligning the locking block with the central slot. Under the action of the return spring, the locking block engages in the central slot, ensuring greater stability of the connecting frame and the sealing block. At this point, both the sealing sleeve and the second sealing gasket are removed from the lower vent, allowing gas to escape. Pulling the upper block upwards again causes the locking block to move away from the central slot and continue upwards to engage in the upper slot, ensuring the stability of the connecting frame and the sealing block. This also causes the sealing sleeve and the second sealing gasket to move away from the upper vent, allowing for faster gas discharge. The invention enables the discharge of gas from the tank at two speeds, facilitating the adaptation to blast holes of two depths and offering excellent applicability. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0020] Depend on Figures 1-5As shown, this utility model provides a dual-speed venting control device for a gas separator, including a gas tank 1. A gas outlet pipe 2 is fixedly connected to the top of the gas tank 1. A pressing device 4 is fixedly connected to the inner side of the gas outlet pipe 2. A connecting frame 6 is movably connected to the outer side of the pressing device 4. A sealing block 3 is fixedly connected to the top of the connecting frame 6. A sealing plate 5 is fixedly connected between adjacent connecting frames 6. The connecting frame 6 includes a frame body 601 movably connected to the outer side of the pressing device 4. The frame body 601 can be raised and lowered in a lifting groove 205. A lifting hole 602 is provided at the lower part of the frame body 601, which is used for the frame body 601 to move along the guide post 401. The frame 601 is raised and lowered from the outside. A locking block 604 is movably connected inside the frame 601, allowing it to move within the frame. A return spring 603 is fixedly connected between the frame 601 and the locking block 604. When the gas in the gas tank 1 is not released, the pressing spring 402 causes the frame 601 to move the first sealing gasket 304 at the bottom of the sealing block 3 against the top of the gas tank 1, sealing the opening 102. Simultaneously, the sealing sleeve 302 and the second sealing gasket 502 seal the vent 208, providing a good seal and preventing gas from overflowing from the gas tank 1. When gas is released from tank 1, pulling the upper block 301 upwards causes the lower block 303 to move the first sealing gasket 304 away from the tank body 101, opening the opening 102 and allowing gas to enter between the tank body 101 and the first sealing gasket 304. Simultaneously, this causes the frame 601 and plate 501 to rise. As they rise, the locking block 604 aligns with the central slot 206. Under the action of the return spring 603, the locking block 604 engages in the central slot 206, thus stabilizing the position of the connecting frame 6 and ensuring the stability of the sealing block 3. At this time, both the sealing sleeve 302 and the second sealing gasket 502 are away from the lower vent 208, allowing the gas to be discharged from the vent 208. By pulling the upper block 301 upward again, the locking block 604 can be removed from the middle locking groove 206 and continue to move upward to lock into the upper locking groove 206, ensuring the stability of the positions of the connecting frame 6 and the sealing block 3. At the same time, both the sealing sleeve 302 and the second sealing gasket 502 are away from the upper vent 208, allowing the gas to be discharged more quickly. The gas in the gas tank 1 can be discharged at two speeds, which is convenient to adapt to the two hole depths of the rupture hole and has good applicability.

[0021] Furthermore, the gas tank 1 includes a tank body 101, and the top of the tank body 101 is provided with an opening 102 for the discharge of gas inside the tank body 101.

[0022] Furthermore, the vent pipe 2 includes a pipe body 201 fixedly connected to the top of the tank body 101. The top of the pipe body 201 is provided with a through hole 202 for the frame body 601 to pass through. The middle of the inside of the pipe body 201 is provided with a pipe hole 203 for the lower block 303 to enter. The inside of the pipe body 201 is provided with a plate groove 204 for the lifting and lowering of the sealing plate 5. The outside of the pipe body 201 is provided with a lifting groove 205, a locking groove 206 and a placement groove 207. The lifting groove 205 is used for the lifting and lowering of the frame body 601, the locking groove 206 is used for the locking block 604 to be inserted, and the placement groove 207 is used for the receiving of the locking block 604. Both the outside and inside of the pipe body 201 are provided with vent holes 208 for the discharge of gas.

[0023] Furthermore, the sealing block 3 includes an upper block 301 fixedly connected to the top of the frame 601, a lower block 303 fixedly connected to the lower part of the upper block 301, a sealing sleeve 302 fixedly connected to the outer side of the lower block 303, the sealing sleeve 302 is used to seal the air outlet 208, and a first sealing gasket 304 fixedly connected to the lower part of the lower block 303, the first sealing gasket 304 is used to close the opening 102.

[0024] Furthermore, the clamping device 4 includes a guide post 401 fixedly connected to the inner side of the outer side of the tube body 201. A clamping spring 402 is movably sleeved on the outer side of the guide post 401. The top of the clamping spring 402 is fixedly connected to the tube body 201, and the bottom is fixedly connected to the frame 601. The clamping spring 402 is in a compressed state, which can stably connect the top post to the frame 6 so that the sealing block 3 can seal the gas tank 1.

[0025] Furthermore, the sealing plate 5 includes a plate 501 fixedly connected between adjacent frames 601. The plate 501 can be raised and lowered in the plate groove 204. A second sealing gasket 502 is fixedly connected to both the outer and inner sides of the plate 501. The second sealing gasket 502 is used to seal the air outlet 208.
