Description

Technical Field

[0001] This utility model relates to the field of emulsion explosive production technology, specifically to a feed pipe for an automatic venting and film-forming machine. Background Technology

[0002] Currently, domestic small-diameter emulsion explosive charging machines have large production capacities, with single-machine output exceeding 4 tons per hour. However, in actual operation, the charging process control fails to achieve the expected results. This is mainly manifested in the generation of a large number of bubbles during the charging process, which seriously affects the quality of the explosives and prevents them from being put into normal production. Specifically, large bubbles are generated during the conveying and stirring of chemically foamed and sensitized emulsion explosives. These gases cannot be effectively removed during the charging process, resulting in a large number of bubbles entering the explosive cartridge along with the explosive during production. This affects product quality and easily leads to detonation failure during blasting operations. This problem is an urgent issue for most emulsion explosive manufacturers to solve. Therefore, to address the above problems, an automatic degassing and film-forming machine guide pipe is designed to better meet the actual use needs. Utility Model Content

[0003] The purpose of this utility model is to provide a guide pipe for an automatic degassing and film-forming machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic venting and film-forming machine guide pipe, including a feeding connection end, the feeding connection end being connected to a conical part, the conical part being connected to a discharge end, and the inner diameter of the discharge end being smaller than the inner diameter of the feeding connection end, and an venting hole being obliquely opened on the outer wall of the discharge end.

[0005] Preferably, the inner diameter of the feed connection end is equal to the inner diameter of the upper end of the conical part, and the inner diameter of the feed connection end is 28mm. By limiting the dimensions of the inner diameter of the feed connection end and the inner diameter of the upper end of the conical part, the smooth movement of the emulsion explosive can be ensured.

[0006] Preferably, a first cutting plate is fixed inside the conical part, and the first cutting plate is distributed at equal angles about the center of the conical part. Through the action of the first cutting plate, the emulsion explosive gathered inside the conical part can be cut, which helps to remove the air bubbles inside the emulsion explosive.

[0007] Preferably, the inner diameter of the discharge end is equal to the inner diameter of the lower end of the conical part, and the inner diameter of the discharge end is 14mm. By limiting the inner diameter of the discharge end and the inner diameter of the lower end of the conical part, the smooth movement of the emulsion explosive can be ensured.

[0008] Preferably, a second cutting plate is also fixed inside the discharge end, and the second cutting plate is distributed at equal angles with respect to the center of the discharge end. There are four sets of the second cutting plate. Through the action of the second cutting plate, the emulsion explosive entering the discharge end can be cut and the gas inside the emulsion explosive can be further discharged.

[0009] Preferably, a spiral guide plate is also fixed inside the discharge end, and the spiral guide plate is fixed inside the discharge end. Through the action of the spiral guide plate, the emulsion explosive can be spirally extruded to ensure that the emulsion explosive is tightly packed.

[0010] Preferably, eight vent holes are provided on the outer wall of the discharge end, and the eight vent holes are divided into four groups at equal intervals from top to bottom, with adjacent groups of vent holes being staggered. The diameter of the two upper groups of vent holes is 5 mm, and the diameter of the two lower groups of vent holes is 6 mm. The vent holes facilitate the discharge of gas from the emulsion explosive, and the inclined structure of the vent holes effectively prevents the explosive from overflowing.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The feed pipe of the automatic venting and film-forming machine adopts a reduced-diameter structure. During the discharge process of the emulsion explosive, by narrowing the movement path of the emulsion explosive, a certain pressure can be increased when the emulsion explosive passes through the feed pipe, thereby achieving automatic venting of the emulsion explosive. Combined with the function of the slitting plate, the emulsion explosive can be slit, which further facilitates the discharge of gas inside the emulsion explosive and improves the venting effect. In addition, the inclined structure of the vent hole can not only facilitate the discharge of gas, but also effectively prevent the material from overflowing. By using this device, large air bubbles in the explosive in the hopper are effectively controlled during the loading process, and large air bubbles will not enter the explosive roll. The weight deviation of the explosive roll is stable, effectively ensuring the production quality of the explosive roll, thereby effectively solving the problem that restricts production.

[0016] 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.

[0017] Please see Figures 1-3 This utility model provides a technical solution: an automatic venting and film-forming machine guide pipe, including a feeding connection end 1, the feeding connection end 1 being connected to a conical part 2, the conical part 2 being connected to a discharge end 3, and the inner diameter of the discharge end 3 being smaller than the inner diameter of the feeding connection end 1, and an venting hole 6 being obliquely opened on the outer wall of the discharge end 3.

[0018] The inner diameter of the feed connection end 1 is equal to the inner diameter of the upper end of the conical part 2, and the inner diameter of the feed connection end 1 is 28mm; a first cutting plate 4 is fixed inside the conical part 2, and the first cutting plate 4 is distributed at equal angles about the center of the conical part 2; the inner diameter of the discharge end 3 is equal to the inner diameter of the lower end of the conical part 2, and the inner diameter of the discharge end 3 is 14mm; a second cutting plate 5 is also fixed inside the discharge end 3, and the second cutting plate 5 is distributed at equal angles about the center of the discharge end 3, and four sets of the second cutting plate 5 are provided; a spiral guide plate 7 is also fixed inside the discharge end 3, and the spiral guide plate 7 is fixed inside the discharge end 3; eight exhaust holes 6 are provided on the outer wall of the discharge end 3, and the eight exhaust holes 6 are divided into four groups at equal intervals from top to bottom, and the adjacent two groups of exhaust holes 6 are staggered, while the diameter of the two upper groups of exhaust holes 6 is 5mm, and the diameter of the two lower groups of exhaust holes 6 is 6mm;

[0019] When using the feed pipe of this automatic venting and film-forming machine, such as Figures 1-3 As shown, the feeding connection end 1 is first installed with the mold closing machine. The emulsion explosive in the hopper is pushed to the mold closing machine by a double-cylinder piston pump, and the emulsion explosive enters the feeding connection end 1. During the process of the emulsion explosive moving from the feeding connection end 1 to the discharge end 3, the first cutting plate 4 can realize the first cutting of the emulsion explosive, which facilitates the discharge of gas inside the emulsion explosive. In addition, with the reduced diameter structure of the conical part 2, the emulsion explosive can be subjected to a certain pressure, further squeezing out the gas inside the emulsion explosive. When the emulsion explosive enters the discharge end 3 and moves downward, the second cutting plate 5 can realize the second cutting of the emulsion explosive, further discharging the gas inside the emulsion explosive. The gas is discharged outward through the exhaust hole 6. The vented material continues to move downward to be extruded by the spiral guide plate 7. Through the guiding action of the spiral guide plate 7, the emulsion explosive can be forcefully gathered again, ensuring the compactness of the emulsion explosive discharged from the discharge end 3. This is the working principle of the guide pipe of the automatic exhaust mold closing machine.
