Fig. 1 is a schematic view of the overall structure of the present invention.
In the figure, 1-a pressure blasting device, 2-a blasting sheet, 3-a gas storage tank, 4-a pressure display meter, 5-a drain valve, 6-a vent pipe, 7-a stop valve, 8-a gas supply pipe, 9-a cooler and 10-an air compressor.
Detailed Description
The invention will be further explained with reference to the drawings and the specific embodiments.
Fig. 1 schematically shows the structure of an air storage tank overpressure protection device for mines according to an embodiment of the present invention.
As shown in fig. 1, the overpressure protection device for the air storage tank used in the mine comprises an air compressor, a cooler, an air storage tank, an air supply pipe, a stop valve, an emptying pipe and a pressure blasting device; the air compressor is connected with the input end of the cooler, and the output end of the cooler is communicated with the air storage tank through an air supply pipe; the stop valve is positioned on the air supply pipe; the emptying pipe is connected to the bottom of the gas storage tank and is communicated with the gas storage tank; the pressure blasting device is connected to the top end of the gas storage tank and comprises a communicating pipe, a blasting piece and a clamp holder, one end of the communicating pipe is communicated with the inside of the gas storage tank, the other end of the communicating pipe is communicated with the air outside the gas storage tank, the clamp holder is positioned in the communicating pipe, and the blasting piece is clamped in the clamp holder.
As shown in fig. 1, the pressure explosion device is used for the explosion of the rupture disk when the pressure in the air storage tank reaches the explosion pressure value of the rupture disk, so that the gas in the air storage tank is released into the air to reduce the pressure in the air storage tank, and the danger of explosion caused by overhigh pressure in the air storage tank is avoided.
As shown in fig. 1, the air compressor cools the compressed air through the cooler and then delivers the cooled compressed air to the air storage tank for storage, so that the air pressure in the air storage tank is continuously increased.
As shown in fig. 1, the pressure value of the rupture disk is 1.25-1.4 times of the maximum working pressure of the air compressor, and when the pressure in the air storage tank is greater than the maximum value that the rupture disk can bear, the rupture disk ruptures.
As shown in FIG. 1, the rupture disk has no fatigue crack, corrosion or other damage phenomena, so that the damage of the rupture disk is avoided to influence the normal blasting of the rupture disk.
As shown in fig. 1, the diameter of the communicating pipe is larger than that of the holder, so that after the rupture disk is ruptured, gas in the gas storage tank is smoothly blown out to the air from the communicating pipe, and the effect that the pressure in the gas storage tank cannot be released due to the smaller diameter of the communicating pipe is avoided.
As shown in fig. 1, the outer surface of the gas storage tank is further provided with a pressure display meter, the sensing end of the pressure display meter is positioned in the gas storage tank, and an operator can check the air pressure value in the gas storage tank through the pressure display meter.
As shown in fig. 1, the drain valve is used for draining accumulated water in the gas storage tank, so that the influence on the gas storage tank caused by excessive accumulated water in the gas storage tank is avoided.
As shown in fig. 1, the stop valve is located on the gas supply pipe to prevent the backflow of the compressed gas.
As shown in figure 1, when the utility model is used, the rupture disk meeting the requirements is arranged in the clamp holder to clean the obstacles or other sundries on the inner wall of the communicating pipe, so that the top end of the communicating pipe is smooth; when the air pressure in the air storage tank reaches the maximum pressure value born by the rupture disk, the rupture disk is exploded, so that the air in the air storage tank is sprayed and discharged to the air outside the air storage tank through the gap of the rupture disk, and the dangers of explosion and the like caused by overhigh air pressure in the air storage tank are avoided; after the rupture disk is exploded, the rupture disk in the pressure blasting device can be replaced for reuse.
What has been described above are only some embodiments of the invention. It will be apparent to those skilled in the art that at least one of the variations and modifications can be made without departing from the inventive concept, and these are intended to be included within the scope of the invention.
