Description

Technical Field

[0001] The invention belongs to the technical field of emulsion explosive transportation, and particularly relates to an emulsion explosive cooling and transportation device and a production process thereof. Background Art

[0002] Emulsion explosives have strong blasting power and good water and frost resistance, and are relatively cheap. They are widely used in underground engineering excavation blasting. Existing emulsion explosives are packaged to form strip-shaped rolls. The outer packaging bag is a plastic film. During packaging, the plastic film is quickly sealed at high temperature. The explosives are then transported in cold water in a cold water pool through an inclined conveying device to quickly cool the rolls.

[0003] Since the explosive rolls are immersed in cold water during cooling, and the conveying device is set at an angle to facilitate the conveying of the cooled explosive rolls above the water level for subsequent packaging, the explosive rolls will be affected by the buoyancy and resistance of the water during transportation, making it difficult to generate stable friction with the conveying device. The explosive rolls may slide relative to the surface of the conveying device during transportation, seriously affecting the underwater transportation efficiency of the explosive rolls.

[0008] As a further optimization solution of the present invention, hinges are installed at both ends of the suspension hook, the hook is hinged to the upper surface of the transmission plate chain through the hinge, and a through hole is opened on a section of the suspension hook located in the gap.

[0009] As a further optimization scheme of the present invention, the pre-cooling device includes an inclined plate arranged above the side baffle and arranged at an angle, and the two sides of the inclined plate are fixed to the side baffle by support rods. The upper surface of the inclined plate is fixedly connected to a water shield, and the top wall of the inner cavity of the water shield is fixedly connected to a spray box. A nozzle is installed on the bottom wall of the spray box, and the end of the water pipe away from the submersible pump is connected to the interior of the spray box.

[0010] As a further optimization scheme of the present invention, a guide plate is fixedly connected to the lower end of the water retaining cover, the guide plate has an arc-shaped structure, the bottom end of the guide plate is fixedly connected to the upper surface of the side baffle, and the distance between the bottom end of the guide plate and the plate chain conveyor belt is smaller than the diameter of the emulsion explosive roll.

[0011] As a further optimization scheme of the present invention, a partition is fixedly installed in the middle of the inner cavity of the negative pressure box, and the water intake of the negative pressure hole opened on the upper surface of the negative pressure box on the side of the partition close to the inclined plate is greater than the water discharge of the pumping pipe.

[0012] As a further optimization scheme of the present invention, the bracket is fixedly connected to a second support plate on one end away from the first support plate, an air pump is fixedly installed on the second support plate, and an exhaust pipe is fixedly connected to the exhaust end of the air pump. The height of the top of the exhaust pipe is higher than the liquid level of the cooling water contained in the cold water tank.

[0013] As a further optimization scheme of the present invention, a blowing pipe with an inner diameter the same as that of the exhaust pipe is fixedly connected to the exhaust end of the air pump, and the end of the blowing pipe away from the air pump is connected to the interior of the negative pressure box on the side of the partition away from the inclined plate.

[0014] A production process for cooling and conveying emulsion explosives, based on an emulsion explosive cooling and conveying device according to any one of claims 1 to 8, comprises the following steps:

[0015] S1. Install the bracket with the plate chain conveyor belt on the top into the cold water tank;

[0016] S2. Pour cooling water of appropriate level into the cold water tank;

[0017] S3. Turn on the submersible pump to start the equipment;

[0018] S4, the explosive rolls are transported to the inclined plate in sequence through the external loading mechanism;

[0019] S5, pre-cooling the explosive coil on the inclined plate by a pre-cooling device;

[0020] S6. Using gravity, the pre-cooled explosive roll falls onto a hanging hook of a plate chain conveyor belt and is submerged in cooling water for cooling;

[0021] S7, using a plate chain conveyor belt to transport the explosive roll to above the cooling water level for draining;

[0022] S8. Use an air pump and an air blow pipe to dry the drained explosive roll.

[0023] The beneficial effects of the present invention are:

[0024] 1. Through the arrangement of the suspension hook, negative pressure box, negative pressure hole, submersible pump, water pumping pipe and other structures, when the explosive roll falls on the suspension hook for suspended transportation, the submersible pump is used in conjunction with the water pumping pipe to pump out the cooling water in the negative pressure box, so that negative pressure is generated in the negative pressure box. Under the action of the negative pressure, the cooling water around the explosive roll quickly flows into the negative pressure box and generates suction to adsorb the explosive roll on the suspension hook. In conjunction with the suspension transportation of the suspension hook, the problem of relative sliding between the explosive roll and the transmission plate chain during underwater transportation, which affects the underwater transportation efficiency of the explosive roll, is avoided as much as possible.

[0025] 2. The cooling water pumped out by the submersible pump can be transported to the spray box installed on the bottom wall of the inner cavity of the water shield through the water pipe. The cooling water is atomized by the nozzle installed at the bottom of the spray box and then sprayed on the inclined plate below. Before introducing the high-temperature explosive roll into the cold water tank, the user can first place the explosive roll on the inclined plate and use the sprayed cooling water to pre-cool the high-temperature explosive roll. The pre-cooled explosive roll then slides to the end of the plate chain conveyor belt submerged in the cooling water for further cooling. This can avoid directly introducing the high-temperature explosive roll into the low-temperature cold water as much as possible. The outer packaging of the explosive roll is easily deformed and cracked due to excessive temperature differences, resulting in leakage of emulsion explosives.

[0026] 3. After the air pump is started, external air is drawn in through an exhaust pipe whose top height is higher than the cooling water level in the cold water tank. The air is transported to the negative pressure box on the side of the partition away from the submersible pump in conjunction with the blower pipe installed on the exhaust end of the air pump, so that the air can be discharged from the negative pressure hole on the top wall of the negative pressure box. The high-speed flowing air acts on the explosive roll to quickly dry the cooled explosive roll, so as to facilitate the subsequent packaging and sealing of the explosive roll.

[0037] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0038] Example

[0039] like Figure 1 - Figure 9As shown, an emulsion explosive cooling and conveying device includes a cold water tank 1 for storing cold water, a balancing pipe 2 for balancing the water temperature inside the cold water tank 1 installed on the cold water tank 1, and the balancing pipe 2 includes a water inlet pipe for replenishing cold water into the cold water tank 1 and a water outlet pipe for discharging hot water in the cold water tank 1. The water inlet pipe and the water outlet pipe are both connected to an external cooling circulation system, and electromagnetic valves are installed at the connection between the water inlet pipe and the water outlet pipe and the cold water tank 1. When in use, cooling water can be introduced into the cold water tank 1 through the water inlet pipe, and the hot water in the cold water tank 1 whose temperature has increased due to heat exchange can be discharged through the water outlet pipe, so that the water level in the cold water tank 1 is maintained constant and always at a low temperature, so as to facilitate rapid heat exchange between the cold water and the emulsion explosive coil, thereby achieving rapid cooling of the emulsion explosive coil;

[0040] A bracket 3 is fixedly installed on the bottom wall of the inner cavity of the cold water tank 1, and side baffles 4 are fixedly installed on the front and rear sides of the bracket 3. The setting of the side baffles 4 can prevent the emulsion explosive from sliding from the two sides of the bracket 3 into the cold water tank 1 as much as possible. A transmission roller 5 is rotatably connected between the two ends of the side baffle 4. Two synchronous belts 6 are sleeved between the ends of the two transmission rollers 5. A plurality of equidistantly distributed transmission plate chains 7 are annularly arranged between the two synchronous belts 6. A suspension hook 71 is provided on the transmission plate chain 7. Hinges 72 are installed at both ends of the suspension hook 71. The suspension hook 71 is hinged to the upper surface of the transmission plate chain 7 through the hinge 72. A gap 8 is formed between adjacent transmission plate chains 7, and the end of the suspension hook 71 away from the transmission plate chain 7 is located in the gap 8;

[0041] The synchronous belt 6 and the transmission plate chain 7 together form an inclined plate chain conveyor belt. One end of the plate chain conveyor belt is immersed in cold water, and the other end of the plate chain conveyor belt is located above the cold water level stored in the cold water tank 1. A servo motor 9 for driving the plate chain conveyor belt to rotate is installed on the side baffle 4. The servo motor 9 is connected to the transmission roller 5 located above the cold water. When the high-temperature explosive roll falls on the end of the plate chain conveyor belt immersed in the cold water, the explosive roll is suspended by a hanging hook 71 hinged on the transmission plate chain 7 to prevent the explosive roll from slipping relative to the plate chain conveyor belt during the rotation of the plate chain conveyor belt. , resulting in the accumulation of explosive rolls on the plate chain conveyor belt. In serious cases, there are too many explosive rolls accumulated on the plate chain conveyor belt, and the explosive rolls cannot be transported through the plate chain conveyor belt. After the explosive rolls fall into the cooling water contained in the cold water tank 1, the cold water in the cold water tank 1 is used to exchange heat with the high-temperature explosive rolls to quickly cool the explosive rolls. At the same time, the servo motor 9 can be started to drive the transmission roller 5 to rotate, thereby cooperating with the synchronous belt 6 to drive the transmission plate chain 7 to rotate and transport the explosive rolls to above the cooling water level. At this time, the water can be quickly drained through the inclined plate chain conveyor belt.

[0042] A negative pressure box 10 is provided in the plate chain conveyor belt. The two ends of the negative pressure box 10 are respectively sleeved on the middle sections of the two transmission rollers 5 and are rotatably connected to the transmission rollers 5. The connection between the transmission rollers 5 and the side walls of the negative pressure box 10 is sealed by a sealed bearing to improve the airtightness of the connection between the transmission rollers 5 and the negative pressure box 10, while reducing the friction resistance of the transmission rollers 5 when rotating.

[0043] The upper surface of the negative pressure box 10 is in sliding contact with the inner ring of the plate chain conveyor belt. A plurality of negative pressure holes 11 are provided in a matrix on the upper surface of the negative pressure box 10. A first support plate 13 is fixedly connected to the lower end of the bracket 3 close to the plate chain conveyor belt. A submersible pump 14 is fixedly connected to the upper surface of the middle section of the first support plate 13. A suction pipe 15 is fixedly connected to the pumping end of the submersible pump 14. The top end of the suction pipe 15 passes through the side baffle 4 and the side wall of the negative pressure box 10 and extends into the negative pressure box 10. In the process of transporting the explosive roll through the plate chain conveyor belt, the submersible pump 14 can be started, and the submersible pump 14 can be used in conjunction with the suction pipe 15 to suck the cooling water in the negative pressure box 10, and the cooling water in the negative pressure box 10 can be pumped out, thereby generating negative pressure in the negative pressure box 10 due to the reduction in water volume. Because a through hole 73 is formed on a section of the hanging hook 71 located in the gap 8 formed between two adjacent transmission plate chains, the cooling water surrounding the explosive roll suspended on the hanging hook 71 will flow rapidly into the negative pressure box 10 through the negative pressure hole 11 under the action of negative pressure. The cooling water that quickly flows into the negative pressure box 10 absorbs the explosive roll suspended and transported by the hanging hook 71, so that the explosive roll can fit tightly with the inner wall of the hanging hook 71, thereby preventing the explosive roll immersed in the cooling water from being separated from the hanging hook 71 due to the buoyancy and resistance of the cooling water, making it difficult to generate stable friction between the hanging hook 71 and the explosive roll, resulting in the hanging hook 71 being unable to stably suspend and transport the explosive roll, thereby affecting the underwater transportation efficiency of the explosive roll;

[0044] A water pipe 16 is fixedly connected to the drainage end of the submersible pump 14, and a pre-cooling device is installed on the side baffle 4 above the first support plate 13. The pre-cooling device includes an inclined plate 18 arranged above the side baffle 4 and arranged at an angle. The two sides of the inclined plate 18 are fixed to the side baffle 4 by support rods 17. A water shield 19 is fixedly connected to the upper surface of the inclined plate 18. A spray box 20 is fixedly connected to the top wall of the inner cavity of the water shield 19. A plurality of equidistantly distributed nozzles 21 are installed on the bottom wall of the spray box 20. The end of the water pipe 16 away from the submersible pump 14 is connected to the inside of the spray box 20. The submersible pump 14 draws water from the negative pressure box 1 through the suction pipe 15. After the cold water is pumped out of the cold water tank 1, it is transported along the water pipe 16 to the spray box 20 above the inclined plate 18, and the cold water is evenly sprayed on the inclined plate 18 using multiple nozzles 21 installed on the bottom wall of the spray box 20. Before the high-temperature explosive coils are introduced into the cold water tank 1 for cooling, the high-temperature explosive coils can be placed on the inclined plate 18 in sequence through an external loading device, and the atomized cold water sprayed by the nozzles 21 is used to pre-cool the high-temperature explosive coils. It is best to avoid directly introducing the high-temperature explosive coils into low-temperature cold water. The outer packaging of the explosive coils is easily deformed and cracked due to excessive temperature differences, resulting in leakage of the emulsion explosive.

[0045] A guide plate 22 is fixedly connected to one end of the water shield 19 at a lower height. The guide plate 22 has an arc-shaped structure. The bottom end of the guide plate 22 is fixedly connected to the upper surface of the side baffle 4. The distance between the bottom end of the guide plate 22 and the plate chain conveyor is smaller than the diameter of the emulsion explosive roll. After the initial pre-cooling by the atomized cold water, the explosive roll will slide down along the inclined plate 18 under the action of its own gravity, and under the guidance of the guide plate 22, it will fall on the end of the plate chain conveyor submerged in the cooling water, and be secondary cooled by the cooling water in the cold water tank 1.

[0046] A partition 12 is fixedly installed in a section of the inner cavity of the negative pressure box 10 located above the cold water level. The water intake per unit time of the negative pressure hole 11 opened on the upper surface of the negative pressure box 10 near the inclined plate 18 of the partition 12 is greater than the water discharge per unit time of the pumping pipe 15, so that cooling water is always present in the section of the negative pressure box 10 immersed in the cooling water, and the problem of insufficient water supply from the negative pressure hole 11, which causes the cooling water in the negative pressure box 10 to be completely drained after the submersible pump 14 has been running for a period of time, resulting in the inability to pre-cool the explosive roll, is avoided as much as possible;

[0047] The bracket 3 is fixedly connected to the second support plate 23 at one end away from the first support plate 13, and an air pump 24 is fixedly installed on the second support plate 23. The air pump 24 is fixedly connected to the air extraction end thereof with an air extraction pipe 25. The top height of the air extraction pipe 25 is higher than the liquid level of the cooling water contained in the cold water tank 1, so that the air pump 24 can suck air from the external environment after it is started. The exhaust end of the air pump 24 is fixedly connected to a blowing pipe 26 with the same inner diameter as the inner diameter of the air extraction pipe 25. The end of the blowing pipe 26 away from the air pump 24 is connected to the partition 12 away from the inclined plate 18. The negative pressure box 10 on one side is internally connected, and the air in the external environment is continuously extracted through the air pump 24 and the exhaust pipe 25, and the air is transported to the inner cavity of the negative pressure box 10 on the side of the partition 12 away from the inclined plate 18 through the blowing pipe 26 installed on the exhaust end of the air pump 24. Finally, the air is discharged through the negative pressure hole 11 opened above the negative pressure box 10 on the side of the partition 12 away from the inclined plate 18, and directly blows the explosive roll passing above it, quickly drying the cooling water attached to the surface of the explosive roll, which is convenient for subsequent packaging and sealing of the explosive roll.

[0048] A production process for cooling and conveying emulsion explosives, based on an emulsion explosive cooling and conveying device according to any one of claims 1 to 8, comprises the following steps:

[0049] S1. Install the bracket 3 with the plate chain conveyor belt 7 installed on the top into the cold water tank 1;

[0050] S2, injecting an appropriate amount of cooling water into the cold water tank 1;

[0051] S3, turn on the submersible pump 14 to start the equipment;

[0052] S4, the explosive rolls are sequentially transported to the inclined plate 18 through the external loading mechanism;

[0053] S5, pre-cooling the explosive roll on the inclined plate 18 by a pre-cooling device;

[0054] S6, using gravity to make the pre-cooled explosive roll fall onto the hanging hook 71 of the plate chain conveyor belt and be cooled on one end thereof which is not immersed in the cooling water;

[0055] S7, using a plate chain conveyor belt to transport the explosive roll to above the cooling water level for draining;

[0056] S8. The drained explosive roll is blown dry by the air pump 24 in cooperation with the air blowing pipe 26.

[0057] It should be noted that, when using the emulsion explosive cooling and conveying device and its production process, first install the bracket 3 with a plate chain conveyor belt on the top in the cold water tank 1, and inject an appropriate amount of cooling water into the cold water tank 1 through the balance pipe 2. At this time, the submersible pump 14 and the air pump 24 can be turned on, and the explosive roll that needs to be cooled is introduced to the top of the inclined plate 18 through the external feeding mechanism. The submersible pump 14 can cooperate with the suction pipe 15 and the water pipe 16 to convey the cold water in the negative pressure box 10 to the spray box 20 installed on the top wall of the inner cavity of the water shield 19, and the atomized cooling water is sprayed on the high-temperature explosive roll through the multiple nozzles 21 installed on the lower surface of the spray box 20 to pre-cool the high-temperature explosive roll. The pre-cooled explosive roll slides down along the inclined plate 18 under the action of its own gravity, and cooperates with the guide plate 22. The guiding effect falls on the end of the plate chain conveyor belt submerged in the cooling water. Since the transmission plate chain 7 is provided with a hanging hook 71 with one end hinged to the transmission plate chain 7 by a hinge 72, a gap 8 is formed between adjacent transmission plate chains 7. The end of the hanging hook 71 away from the transmission plate chain 7 is located in the gap 8, and a through hole 73 is opened on the section of the hanging hook 71 located in the gap 8. After the explosive roll falls on the plate chain conveyor belt, it will be hung above the gap 8 formed between the adjacent transmission plate chains 7 by the hanging hook 71 and transported along the plate chain conveyor belt. Since the high-temperature explosive roll is pre-cooled by spraying cooling water with the spray box 20 and the nozzle 21 before the cold water tank 1, it can be avoided as much as possible to directly introduce the high-temperature explosive roll into the low-temperature cold water. The outer packaging of the explosive roll is easily deformed and cracked due to excessive temperature difference, resulting in the problem of leakage of emulsion explosive;

[0058] In the process of the submersible pump 14 cooperating with the suction pipe 15 and the water delivery pipe 16 to suck the cooling water in the negative pressure box 10 into the spray box 20 to pre-cool the explosive roll, the cooling water in the negative pressure box 10 is pumped out, thereby generating a negative pressure in the negative pressure box 10 due to the reduction of water volume. At this time, the cooling water around the explosive roll suspended on the suspension hook 71 will flow rapidly into the negative pressure box 10 through the through hole 73 and the negative pressure hole 11 under the action of negative pressure. The cooling water that flows rapidly into the negative pressure box 10 absorbs the explosive roll so that the explosive roll can fit tightly with the inner wall of the suspension hook 71, so as to prevent the explosive roll immersed in the cooling water from being separated from the suspension hook 71 due to the buoyancy and resistance of the cooling water, and it is difficult to generate a stable friction force between the suspension hook 71, resulting in the suspension hook 71 being unable to stably suspend and transport the explosive roll, thereby affecting the underwater transportation efficiency of the explosive roll.

[0059] At the same time, after the air pump 24 is started, it draws in external air through the exhaust pipe 25 whose top height is higher than the cooling water level in the cold water tank 1, and cooperates with the blower pipe 26 installed on the exhaust end of the air pump 24 to transport the fast-flowing air to the negative pressure box 10 on the side of the partition 12 away from the submersible pump 14, so that the air can be discharged through the negative pressure hole 11 opened on the top wall of the negative pressure box 10. The high-speed flowing air is used to act on the explosive roll to quickly dry the cooled explosive roll, so as to facilitate the subsequent packaging and sealing of the explosive roll.

[0060] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
