Emulsion explosive processing equipment and production process

Abstract

This invention relates to the field of emulsion explosive processing, specifically to an emulsion explosive processing device, comprising a mixing tank. A transmission rod is rotatably connected to the middle of the inner wall of the mixing tank. A motor is fixedly connected to the right end of the transmission rod through the mixing tank. The side wall of the motor is fixedly connected to the side wall of the mixing tank. Four support rings are fixedly connected at equal intervals along the circumference of the transmission rod. This emulsion explosive processing device consists of an exhaust mechanism and a mixing mechanism. When the motor is started, the transmission rod drives a U-shaped mixing plate to stir the explosive mixture inside the mixing tank. The piston rod on the U-shaped mixing plate presses against the surface of an eccentrically set arc-shaped pressure plate, causing the piston rod to gradually move into the gas collecting cylinder. At this time, the gas pressure inside the U-shaped exhaust groove increases and presses against the conical sealing gasket, causing gas to be continuously discharged from the exhaust hole. As the U-shaped mixing plate rotates, it ensures that the bubbles are evenly dispersed inside the explosive mixture, improving the sensitization effect of explosive production.

Description

TECHNICAL FIELD

[0001] The present application relates to the field of emulsion explosive processing, in particular to an emulsion explosive processing equipment and production process. BACKGROUND

[0002] Emulsion explosive is a new type of explosive developed in the late 1960s. With the surface activity of emulsifier, the oxidant aqueous solution is wrapped in the oil phase material to form a water-in-oil emulsion matrix, and then through mixing with small bubbles for sensitization, an explosive with explosion performance is formed. The production process needs to be processed by mixing equipment.

[0003] The existing patent (publication number: CN114195602A) discloses an emulsion explosive feeding device, and relates to the technical field of emulsion explosive feeding. The emulsion explosive feeding device comprises a bottom support, a guide wall cylinder is installed on the upper end of the bottom support near the right side, and a ceiling frame is combined and installed on the upper end surface of the guide wall cylinder. The inventor found that the following problems in the prior art have not been well solved in the process of implementing this scheme: 1. During the use of the emulsion explosive production device, the air ring is used to turn in and out of the emulsion explosive raw materials, and small perforations are used to mix small bubbles into the emulsion explosive raw materials for sensitization. During the cooperation of the air ring and the small perforations, a large number of bubbles will only adhere to the upper part of the mixture, and there will be fewer bubbles towards the inner bottom surface of the mixture, which makes it difficult to uniformly distribute the bubbles in the interior of the mixture, thereby affecting the sensitization effect.

[0016] Both ends of the rotating rod are fixedly connected to spur gears, and the inner top surface of the mixing tank is fixedly connected to an arc-shaped toothed plate that mates with the spur gears.

[0017] Preferably, the rotating plate is an arc-shaped plate, and the surface of the rotating plate has through holes.

[0018] Preferably, the arc-shaped toothed plate is set to 0.46 times the inner diameter of the mixing tank;

[0019] The three arc-shaped toothed plates are configured, and each of the three arc-shaped toothed plates corresponds to one of the three rotating rods. The sidewall of the arc-shaped toothed plate meshes with the sidewall of the adjacent circular gear.

[0020] A manufacturing process for an emulsion explosive processing equipment includes the following steps:

[0021] S1. When producing emulsion explosives, first add the emulsion explosive raw materials into the inside of the mixing tank, so that the emulsion explosive raw materials are deposited in the lower part of the inner wall of the mixing tank. Then start the motor to drive the transmission rod to rotate, so that the transmission rod, carrying the support ring, rotates synchronously with the rotating rod.

[0022] S2. When the support ring rotates with the four U-shaped mixing plates on the surface to mix and stir the emulsion explosive raw materials, when the piston rod on the gas collecting cylinder in the middle of the U-shaped mixing plate rotates to the position of the eccentrically set arc-shaped pressure plate, as the U-shaped mixing plate continues to rotate, the arc-shaped pressure plate squeezes the piston rod to move slowly inside the gas collecting cylinder. At this time, the gas inside the gas collecting cylinder and the U-shaped exhaust groove is compressed, causing the T-shaped connecting rod and the conical sealing gasket to move and release the seal on the exhaust hole. At this time, the exhaust hole position continues to exhaust gas to the outside of the U-shaped mixing plate. As the U-shaped mixing plate rotates, the discharged bubbles are evenly dispersed inside the mixture.

[0023] S3. When the U-shaped mixing plate continues to rotate to the upper position of the inner wall of the mixing tank, the T-shaped sealing blocks at both ends of the U-shaped mixing plate are pressed by the arc-shaped guide plate. At this time, the T-shaped sealing blocks are released from contact with the conical magnetic ring, and the air inlet is released from the sealing state. This causes the compression spring to press the piston rod to quickly reset inside the air collecting cylinder. The air collecting cylinder generates negative pressure and draws external gas into the air collecting cylinder through the U-shaped exhaust groove and the air inlet position for gas replenishment. When the T-shaped sealing block continues to rotate and releases contact with the arc-shaped guide plate, the pressing spring presses the T-shaped sealing block to reset and seal the air inlet position, allowing the continuing to rotate U-shaped mixing plate to re-enter the mixture for exhaust.

[0024] S4. During the rotation of the rotating rod, the spur gear at one end of the rotating rod moves along the trajectory of the arc-shaped toothed plate. At this time, the spur gear meshes with the arc-shaped toothed plate, causing the spur gear to rotate inside the transmission hole. The rotating rod, along with the rotating ring, rotates synchronously with the rotating plate, causing the rotating plate at the other end of the rotating rod to stir the mixture and air bubbles between the two adjacent U-shaped mixing plates. After the mixture has completed mixing and sensitization, the produced emulsion explosive mixture is discharged and collected from the unloading cylinder.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] In this invention, through the coordinated use of components such as a U-shaped mixing plate, piston rod, and arc-shaped pressure plate, when the motor starts and the transmission rod drives the U-shaped mixing plate to stir the explosive mixture inside the mixing tank, the piston rod on the U-shaped mixing plate presses against the eccentrically set surface of the arc-shaped pressure plate, causing the piston rod to gradually move into the gas collecting cylinder. At this time, the gas pressure inside the U-shaped exhaust groove increases and presses against the conical sealing gasket, causing gas to be continuously discharged from the exhaust hole. As the U-shaped mixing plate rotates, it ensures that the bubbles are evenly dispersed inside the explosive mixture, thereby improving the sensitization effect of explosive production.

[0027] In this invention, through the coordinated use of components such as the rotating rod, rotating plate, and arc-shaped toothed plate, as the transmission rod rotates the U-shaped mixing plate and continuously discharges bubbles, the bubbles are distributed around the moving trajectory of the U-shaped mixing plate. At this time, when the transmission rod rotates synchronously with the rotating rod, the circular gear at one end of the rotating rod meshes with the side wall of the arc-shaped toothed plate on the inner wall of the mixing tank, causing the rotating rod to rotate with the rotating plate, uniformly stirring the explosive mixture and bubbles between the two U-shaped mixing plates, further improving the uniformity of bubble dispersion.

[0028] In this invention, through the combined use of components such as the T-shaped sealing block, the conical magnetic ring, and the pressing spring, when the U-shaped mixing plate rotates to the upper part of the inner wall of the mixing tank, the T-shaped sealing block on the U-shaped mixing plate contacts the arc-shaped guide plate, causing the T-shaped sealing block to be compressed and released from its seal with the conical magnetic ring. At this time, the compression spring can reset the piston rod and generate negative pressure, drawing external gas into the U-shaped exhaust groove and the gas collecting cylinder. By performing fixed-point gas collection, the mixture is prevented from entering the U-shaped exhaust groove and the gas collecting cylinder, thus improving the gas storage effect.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1 to 10This invention provides a technical solution: an emulsion explosive processing device, comprising a mixing tank 1, a transmission rod 2 rotatably connected to the middle of the inner wall of the mixing tank 1, and a motor 3 fixedly connected to the right end of the transmission rod 2 through the mixing tank 1. The side wall of the motor 3 is fixedly connected to the side wall of the mixing tank 1. It should be noted that a connecting bearing is fixedly connected between the left end of the transmission rod 2 and the inner wall of the mixing tank 1 to ensure that the transmission rod 2 rotates stably inside the mixing tank 1.

[0042] Four support rings 4 are fixedly connected at equal intervals along the circumference of the surface of the transmission rod 2. An exhaust mechanism 5 is movably connected between the outer ring of the support ring 4 and the inner wall of the mixing tank 1.

[0043] The surface of the support ring 4 is provided with three transmission holes 6 at equal intervals. The three transmission holes 6 are equally spaced between the four support rings 4. The interior of the transmission holes 6 is movably connected to the inner wall of the mixing tank 1 by a mixing mechanism 7.

[0044] A feed cylinder 8 is provided on the upper right side of the mixing tank 1, and a discharge cylinder 9 is provided at the bottom of the mixing tank 1.

[0045] In this embodiment, as Figures 1 to 10 As shown, the exhaust mechanism 5 includes a U-shaped mixing plate 501. There are four U-shaped mixing plates 501. The four U-shaped mixing plates 501 are fixedly connected to the outer ring of the support ring 4 at equal intervals along the circumference. A gas collecting cylinder 503 is fixedly connected to the middle of the U-shaped mixing plate 501. A piston rod 504 is slidably connected inside the gas collecting cylinder 503. A compression spring 505 is fixedly connected between one end of the piston rod 504 and the inner wall of the gas collecting cylinder 503. An arc-shaped pressure plate 506 that cooperates with the other end of the piston rod 504 is eccentrically arranged on the lower part of the inner wall of the mixing tank 1. It should be noted that the width of the arc-shaped pressure plate 506 is set to 0.8 times the width of the groove in the middle of the U-shaped mixing plate 501, so as to avoid interference when the U-shaped mixing plate 501 rotates to the position of the arc-shaped pressure plate 506, and to ensure that the arc-shaped pressure plate 506 can stably enter the groove in the middle of the U-shaped mixing plate 501; there are four arc-shaped pressure plates 506, and the four arc-shaped pressure plates 506 correspond one-to-one with the four U-shaped mixing plates 501.

[0046] The U-shaped mixing plate 501 has a U-shaped exhaust groove 507 inside that mates with the gas collecting cylinder 503. Sixteen exhaust holes 508, equidistantly spaced on both sides of the U-shaped mixing plate 501, also mate with the U-shaped exhaust grooves 507. A T-shaped connecting rod 509 is slidably connected inside each exhaust hole 508. A conical sealing gasket 510 is fixedly connected to one end of the T-shaped connecting rod 509, with its sidewall overlapping the inner wall of the exhaust hole 508. A short spring 511 is movably sleeved on the side of the T-shaped connecting rod 509 away from the conical sealing gasket 510, with one end of the short spring overlapping the inner wall of the exhaust hole 508. It should be noted that a circular hole mates with the U-shaped exhaust groove 507 is provided in the middle of the inner wall of the gas collecting cylinder 503, allowing gas inside the gas collecting cylinder 503 to enter the U-shaped exhaust groove 507.

[0047] Both ends of the U-shaped mixing plate 501 are provided with air inlets 512 that cooperate with the U-shaped exhaust groove 507. A T-shaped sealing block 513 is slidably connected inside the air inlet 512. A conical magnetic ring 514 is fixedly connected to the inner wall of the air inlet 512. One side of the T-shaped sealing block 513 overlaps with the inner wall of the conical magnetic ring 514. A pressing spring 515 is fixedly connected between the side wall of the T-shaped sealing block 513 and the inner wall of the air inlet 512. An arc-shaped guide plate 502 that cooperates with the T-shaped sealing block 513 is fixedly connected to the inner top surface of the mixing tank 1. It should be noted that: both ends of the U-shaped mixing plate 501 are provided with recesses that match the air inlet 512, and the end of the T-shaped sealing block 513 away from the pressing spring 515 will not move out of the recess, so as to avoid the T-shaped sealing block 513 from contacting the inner wall of the mixing tank 1 and causing interference; the end of the T-shaped sealing block 513 near the conical magnetic ring 514 is set to be conical, so as to facilitate the sealing with the conical magnetic ring 514.

[0048] In this embodiment, as Figures 1 to 10 As shown, the other end of the piston rod 504 is fixedly connected to a ball head that mates with the arc-shaped pressure plate 506. A pad is symmetrically fixedly connected to the bottom of the arc-shaped pressure plate 506, and the pad is fixedly connected to the inner wall of the mixing tank 1. It should be noted that the two pads have the same structure but different lengths, thus allowing the arc-shaped pressure plate 506 to be eccentrically positioned inside the mixing tank 1.

[0049] The inner wall of the gas collecting cylinder 503 is symmetrically and fixedly connected with stop blocks that cooperate with the piston rod 504. It should be noted that the stop blocks are designed to prevent the piston rod 504 from moving out of the inside of the gas collecting cylinder 503.

[0050] In this embodiment, as Figures 1 to 10As shown, the inner wall of the vent 508 near the conical sealing gasket 510 is conical, and rectangular blocks that cooperate with the T-shaped connecting rod 509 are symmetrically fixed to the inner wall of the vent 508. It should be noted that: by setting the rectangular blocks, when the T-shaped connecting rod moves with the conical sealing gasket 510 to vent, the T-shaped connecting rod will not seal the position of the vent 508, thus affecting the performance.

[0051] In this embodiment, as Figures 1 to 10 As shown, the end of the T-shaped sealing block 513 furthest from the pressing spring 515 is arc-shaped, and the T-shaped sealing block 513 is made of iron. It should be noted that when the T-shaped sealing block 513 on the U-shaped mixing plate 501 rotates to the position of the arc-shaped guide plate 502, the arc-shaped end of the T-shaped sealing block 513 is pressed and moves into the air inlet 512. At this time, the gas flows from the air inlet 512 into the U-shaped exhaust groove 507 and the air collection cylinder 503. The iron block can effectively adhere and seal with the conical magnetic ring 514, preventing the compression spring 505 from resetting the piston rod 504 and generating negative pressure, which would cause the T-shaped sealing block 513 to move. Only when the T-shaped sealing block 513 is squeezed by the arc-shaped guide plate 502 can the compression spring 505 reset and move the piston rod 504.

[0052] In this embodiment, as Figures 1 to 10 As shown, the mixing mechanism 7 includes a support bearing 701. The outer ring of the support bearing 701 is fixedly connected to the inner wall of the transmission hole 6. The inner ring of the support bearing 701 is fixedly connected to a rotating rod 702. Five rotating rings 703 are symmetrically fixedly connected to both sides of the rotating rod 702. Four rotating plates 704 are fixedly fixedly connected at equal intervals along the circumference of the outer ring of the rotating ring 703.

[0053] Both ends of the rotating rod 702 are fixedly connected to spur gears 705, and the inner top surface of the mixing tank 1 is fixedly connected to an arc-shaped toothed plate 706 that mates with the spur gears 705.

[0054] In this embodiment, as Figures 1 to 10 As shown, the rotating plate 704 is an arc-shaped plate, and through holes are opened on the surface of the rotating plate 704. It should be noted that: when the rotating rod 702 rotates with the arc-shaped rotating plate 704, it can stir the mixture between the two U-shaped mixing plates 501, so that the bubbles are evenly distributed outside the rotation trajectory of the U-shaped mixing plates 501, further improving the uniformity of bubble dispersion.

[0055] In this embodiment, as Figures 1 to 10 As shown, the arc-shaped toothed plate 706 is set to 0.46 times the inner diameter of the mixing tank 1. It should be noted that when the upper end of the rotating rod 702 meshes with the surface of the arc-shaped toothed plate 706 through the spur gear 705, the lower end of the rotating rod 702 can effectively rotate and stir inside the explosive mixture.

[0056] There are three arc-shaped toothed plates 706, and the three arc-shaped toothed plates 706 correspond one-to-one with the three rotating rods 702. The side wall of the arc-shaped toothed plate 706 meshes with the side wall of the adjacent spur gear 705.

[0057] In this embodiment, as Figures 1 to 10 As shown, the production process of an emulsion explosive processing equipment includes the following steps:

[0058] S1. When producing emulsion explosives, the emulsion explosive raw materials are first added to the inside of the mixing tank 1, so that the emulsion explosive raw materials are deposited in the lower part of the inner wall of the mixing tank 1. Then, the motor 3 is started to drive the transmission rod 2 to rotate, so that the transmission rod 2, carrying the support ring 4, rotates synchronously with the rotating rod 702.

[0059] S2. When the support ring 4 rotates with the four U-shaped mixing plates 501 on its surface to mix and stir the emulsion explosive raw materials, the piston rod 504 on the gas collecting cylinder 503 in the middle of the U-shaped mixing plate 501 rotates to the position of the eccentrically set arc-shaped pressure plate 506. As the U-shaped mixing plate 501 continues to rotate, the arc-shaped pressure plate 506 squeezes the piston rod 504 to move slowly inside the gas collecting cylinder 503. At this time, the gas inside the gas collecting cylinder 503 and the U-shaped exhaust groove 507 is compressed, causing the T-shaped connecting rod 509 and the conical sealing gasket 510 to move and release the seal on the exhaust hole 508. At this time, the exhaust hole 508 continues to exhaust gas to the outside of the U-shaped mixing plate. As the U-shaped mixing plate 501 rotates, the discharged bubbles are evenly dispersed inside the mixture.

[0060] S3. When the U-shaped mixing plate 501 continues to rotate to the upper position of the inner wall of the mixing tank 1, the T-shaped sealing blocks 513 at both ends of the U-shaped mixing plate 501 are pressed by the arc-shaped guide plate 502. At this time, the T-shaped sealing blocks 513 are released from contact with the conical magnetic ring 514, and the air inlet 512 is released from the sealing state. The compression spring 505 presses the piston rod 504 to quickly reset inside the gas collecting cylinder 503. The negative pressure generated inside the gas collecting cylinder 503 draws external gas into the gas collecting cylinder 503 through the U-shaped exhaust groove 507 and the position of the air inlet 512 for gas replenishment. When the T-shaped sealing block 513 continues to rotate and releases contact with the arc-shaped guide plate 502, the pressing spring 515 presses the T-shaped sealing block 513 to reset and seal the position of the air inlet 512, so that the U-shaped mixing plate 501, which continues to rotate, re-enters the mixture for exhaust.

[0061] S4. During the rotation of the rotating rod 702, the spur gear 705 at one end of the rotating rod 702 moves along the trajectory of the arc-shaped toothed plate 706. At this time, the spur gear 705 meshes with the arc-shaped toothed plate 706, causing the spur gear 705 to carry the rotating rod 702 to rotate inside the transmission hole 6. The rotating rod 702 carries the rotating ring 703 and rotates synchronously with the rotating plate 704, causing the rotating plate 704 at the other end of the rotating rod 702 to stir the mixture and air bubbles between the two adjacent U-shaped mixing plates 501. After the mixture has completed mixing and sensitization, the produced emulsion explosive mixture is discharged and collected from the unloading cylinder 9.

[0062] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
