[0002] In mining operations, drilling and blasting are required. In order to reduce the amount of explosives used during blasting, as well as to reduce vibration and improve the utilization efficiency of explosives, gas spacers are usually used.
[0003] A search revealed that patent CN209197587U discloses a gas separator venting device, including an aerosol button, an inner cover, an outer cover, a support, and a valve stem. The inner cover is fitted onto the aerosol button and has an air jet hole on its top surface. The outer cover is fitted onto the inner cover and has a central hole and side holes for air jetting. A bead is placed on the central hole to seal it. The valve stem is hinged in a groove in the support. The front end of the valve stem is a pressing part with a wavy bottom surface, and an air passage is opened in the middle of the valve stem. The rear part of the valve stem is an operating lever. This invention can realize the switching between slow venting with a single hole and fast venting with two holes, and has the advantages of easier manufacturing, lower cost, and easier guarantee of hole diameter size. By operating the valve stem up or down, either slow venting with a single hole or fast venting with two holes can be selected, making operation simple and flexible, and meeting the actual needs of various working conditions.
[0004] Because gas spacers of different hole depths are placed in different positions, the required time for lowering them into the blast hole varies. However, existing gas spacer venting devices cannot adjust the venting rate during use, causing the gas bladder of the gas spacer to easily fold during inflation. Summary of the Invention
[0005] The purpose of this invention is to provide a gas separator venting device with adjustable venting speed to solve the problems mentioned in the background art.
[0006] In view of this, the present invention provides a gas separator venting device with adjustable venting speed, comprising an air bladder, an anti-slip ring on the outer wall of the air bladder, an inflatable frame at the top of the air bladder, an air inlet on the outer wall of the inflatable frame, a screw threaded to the top of the inflatable frame, a knob fixedly connected to the top of the screw, a lifting valve body screwed to the bottom of the screw, a sealing ring on the outer wall of the lifting valve body, a limit groove at the connection between the inflatable frame and the lifting valve body, a connecting hole on the outer wall of the lifting valve body, an air outlet on the outer wall of the inflatable frame, a connecting pipe fixedly connected to the outer wall of the air outlet, an inflation port on the outer wall of the connecting pipe, a base at the bottom of the air bladder, a support rod fixedly connected to the connection between the base and the inflatable frame, and a counterweight at the bottom of the base.
[0007] Based on the above structure, when the screw rotates, it drives the lifting valve body to slide along the groove of the limiting groove through the thread; by setting a sealing ring, it is beneficial to improve the sealing performance of the inflation frame; when the lifting valve body slides, it drives the three sets of connecting holes to move relative to the air outlet; by adjusting the relative position of the three sets of connecting holes and the air outlet, it is easy to adjust the venting diameter, thereby realizing the adjustment of the venting speed.
[0008] Preferably, the anti-slip rings are evenly distributed along the outer wall of the airbag. In this embodiment, the airbag is inflated so that the anti-slip rings on the outer wall of the airbag fit tightly against the inner wall of the borehole, preventing the airbag from slipping off.
[0009] Preferably, the central axis of the inflatable frame coincides with the central axis of the airbag. In this embodiment, this facilitates uniform inflation of the airbag.
[0010] Preferably, the lifting valve body forms a lifting structure through the screw and the limiting groove. In this embodiment, when the screw rotates, it drives the lifting valve body to slide along the groove of the limiting groove through the thread, thereby realizing the sliding control of the lifting valve body.
[0011] Preferably, the connecting holes are provided in three sets, and the length between the three sets of connecting holes is equal to the height of the air outlet. In this embodiment, when the lifting valve body slides, it drives the three sets of connecting holes to move relative to the air outlet.

[0013] Preferably, the inflation ports are equidistantly distributed along the outer wall of the connecting tube. In this embodiment, this facilitates the injection of high-pressure gas into the connecting tube through the connecting holes and the air outlet, and its discharge from the inflation ports on the outer wall of the connecting tube, thereby achieving uniform inflation of the airbag and preventing the airbag from folding.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model is provided with connecting holes and air outlets. When the screw rotates, it drives the lifting valve body to slide along the groove of the limiting groove through the thread. By setting a sealing ring, it is beneficial to improve the sealing performance of the inflation frame. When the lifting valve body slides, it drives the three sets of connecting holes and the air outlet to move relative to each other. By adjusting the relative position of the three sets of connecting holes and the air outlet, it is easy to adjust the venting diameter, thereby realizing the adjustment of the venting speed.
[0016] 2. This utility model is equipped with a connecting pipe. The inflation device injects high-pressure gas into the inflation frame through the air inlet.

Then, the airbag inflates and expands, so that the anti-slip ring on the outer wall of the airbag fits tightly against the inner wall of the blast hole, thus achieving air gap in the blast hole.

[0025] Based on the above structure, when the screw 5 rotates, it drives the lifting valve body 7 to slide along the groove of the limiting groove 8 through the thread; by setting the sealing ring 701, it is beneficial to improve the sealing performance of the inflation frame 3; when the lifting valve body 7 slides, it drives the three sets of connecting holes 9 to move relative to the air outlet 10; by adjusting the relative position of the three sets of connecting holes 9 and the air outlet 10, it is easy to adjust the venting diameter, thereby realizing the adjustment of the venting speed.
[0026] In one embodiment, the anti-slip rings 2 are equidistantly distributed along the outer wall of the airbag 1.
[0027] The airbag 1 inflates, causing the anti-slip ring 2 on the outer wall of the airbag 1 to fit tightly against the inner wall of the borehole, thus preventing the airbag 1 from slipping off.
[0028] In one embodiment, the central axis of the inflatable frame 3 coincides with the central axis of the airbag 1, which is beneficial for uniform inflation of the airbag 1.
[0029] In one embodiment, the lifting valve body 7 forms a lifting structure between the screw 5 and the limiting groove 8.
[0030] When the screw 5 rotates, it drives the lifting valve body 7 to slide along the groove of the limiting groove 8 through the thread, thereby controlling the sliding of the lifting valve body 7.
[0031] In one embodiment, three sets of connection holes 9 are provided, and the length between the three sets of connection holes 9 is equal to the height of the air outlet 10.
[0032] When the lifting valve body 7 slides, it drives the three sets of connecting holes 9 to move relative to the air outlet 10. The relative position of the three sets of connecting holes 9 and the air outlet 10 makes it easy to adjust the venting diameter, thereby adjusting the venting speed.

The knob 6 drives the screw 5 to rotate, and the screw 5 drives the lifting valve body 7 to slide along the groove of the limiting groove 8 through the thread. By setting the sealing ring 701, the sealing performance of the inflation frame 3 is improved. When the lifting valve body 7 slides, it drives the three sets of connecting holes 9 to move relative to the air outlet 10. The relative position of the three sets of connecting holes 9 and the air outlet 10 makes it easy to adjust the air release diameter, thereby realizing the adjustment of the air release speed.
[0037] Then, the airbag 1 is placed in the borehole by the counterweight 15; next, the inflation device injects high-pressure gas into the inflation frame 3 through the air inlet 4. The high-pressure gas is injected into the injection connecting pipe 11 through the connecting hole 9 and the air outlet 10, and is discharged from the inflation port 12 on the outer wall of the connecting pipe 11, so as to achieve uniform inflation of the airbag 1 and prevent the airbag 1 from folding.
