Description

Technical Field

[0001] The invention relates to the technical field of mining blasting, and in particular to a damaged emulsion explosive reshaping device and a reshaping method. Background Art

[0002] Emulsion explosives are widely used in mining operations at home and abroad due to their good explosive performance, reliable safety performance, strong water resistance and many other advantages. As a special emulsified continuous medium explosive of oil-in-water type, emulsion explosives can be divided into powder roll products, bagged products, bulk products, latex solution products, and latex ammonium oil explosive blended products according to packaging form and product form. Among them, powder roll products are more commonly used in mining blasting at home and abroad because of their convenient operation and convenient charging.

[0003] Emulsion explosive rolls are wrapped in plastic film into cylindrical rolls. Due to packaging technology reasons and improper subsequent storage, the plastic film wrapping the emulsion explosive rolls may burst along the cylindrical sealing line, causing the emulsion explosive packaging to be damaged and cause the agent to leak, and then it will be impossible to continue loading. The explosive composition inside such rolls with damaged outer packaging has not changed. If this type of explosive is directly abandoned as emulsion explosive waste, the cost of using explosives and the workload of handling are increased.

[0004] At present, one of the treatment methods for emulsion explosives with damaged outer plastic film is to directly ignore the damage of the emulsion explosive packaging and carry out the charging operation. However, since the emulsion explosive loses the outer plastic film after charging, the coupling of the drug bag in the blast hole and the change of the charging structure cannot be controlled, and the leaked agent of the damaged explosive is easy to adhere to the inner wall of the blast hole, resulting in the subsequent charging operation not being smooth, and even blocking the hole, which is easy to cause large pieces and increase the burden of secondary damage. Another treatment method is to completely remove the plastic film outer packaging of the damaged emulsion explosives, and re-chemically separate and reprocess the components of the emulsion explosive as waste, such as the emulsion explosive waste drug treatment device and method disclosed in CN105111030A, but this method is time-consuming and labor-intensive, increases the cost of explosive treatment and environmental protection, and the separation and harmless treatment of explosive components have high requirements and need to be carried out in a special explosive production workshop. General mining enterprises cannot carry out it alone, and safety is difficult to guarantee.

[0005] Therefore, how to deal with damaged emulsion explosives to achieve a balance between economy and safety is a technical problem to be solved. Summary of the invention

[0006] In order to solve the above technical problems, the present invention firstly provides a device for reshaping damaged emulsion explosives.

[0007] The present invention adopts the following technical solutions:

[0008] A damaged emulsion explosive reshaping device comprises a plastic sealing roll shaft and a medicine roll shaft arranged in parallel, wherein the plastic sealing roll shaft and the medicine roll shaft are detachably arranged on a bracket, and the plastic sealing roll shaft and the medicine roll shaft are respectively rotatably connected to the bracket, and the medicine roll shaft also has a gap for placing damaged emulsion explosive medicine rolls, and the medicine roll shaft is respectively provided with clamping pieces on both sides of the gap for fixing the damaged emulsion explosive medicine rolls.

[0009] Preferably, it also includes a medicine roll shaft transmission rod, which is arranged parallel to the medicine roll shaft, and both ends of the medicine roll shaft transmission rod are fixedly connected to the medicine roll shafts on both sides of the gap through transmission brackets, and the transmission brackets maintain the synchronous rotation of the medicine roll shafts on both sides of the gap.

[0010] Preferably, the transmission bracket is a telescopic bracket, and the transmission bracket is used to adjust the transmission rod of the medicine roll rotating shaft to be close to the outer surface of the damaged emulsion explosive medicine roll.

[0011] Preferably, two groups of the drug roll rotating shaft transmission rods are symmetrically arranged outside the damaged emulsion explosive drug roll, and the shape of the drug roll rotating shaft transmission rods is set to fit the concave surface of the outer surface of the damaged emulsion explosive drug roll.

[0012] Preferably, the support comprises two pairs of support rods respectively supporting the plastic sealing roll rotating shaft and the medicine roll rotating shaft, and the bottoms of the support rods are connected as one body through a base.

[0013] Preferably, a through hole is provided at the top of the support rod, and a rotation gap exists between the plastic wrapping reel and the through hole of the oppositely arranged support rod, or a rotating member is provided between the through hole to allow the plastic wrapping reel to rotate around its axis on the bracket.

[0014] Preferably, there is a rotation gap between the medicine roll rotating shaft and the through hole of the oppositely arranged support rod, or a rotating member is arranged between the through hole to allow the plastic packaging roll rotating shaft to rotate around its axis on the bracket.

[0015] Preferably, the plastic sealing roll shaft and the medicine roll shaft are both retractable rods.

[0016] Preferably, a turntable is provided at any one end or both ends of the medicine roll shaft.

[0017] Preferably, the turntable is connected to a motor, or a rotating rocker is provided on the turntable.

[0018] Preferably, the clamping member is detachably arranged on the medicine roll shaft, and the bite force of the clamping member is greater than 80KN.

[0019] The present invention also provides a method for reshaping a damaged emulsion explosive reshaping device as described above, comprising the following steps:

[0020] S1. Check the validity period and danger and transportation signs of the damaged emulsion explosives to ensure that they are identifiable and confirm that the explosives in the damaged emulsion explosives meet the specifications for continued use;

[0021] S2. The sealing rings at both ends of the screened qualified damaged emulsion explosive rolls are fixedly connected to the clamping members on the roll shaft, so that the damaged emulsion explosive rolls have the ability to rotate with the roll shaft, and the transmission bracket is adjusted so that the drive rod of the roll shaft fits the outer surface of the damaged emulsion explosive roll;

[0022] S3. Select a plastic-sealed roll corresponding to the length of the damaged emulsion explosive roll and install it on the plastic-sealed roll bracket, and pull the plastic film end of the plastic-sealed roll to the surface of the damaged emulsion explosive roll for bonding and fixing, and rotate the roll shaft so that the plastic film of the plastic-sealed roll is wrapped around the damaged emulsion explosive roll;

[0023] S4. After the plastic film is wound for a set number of times, the plastic film is cut, and after the drive rod of the medicine roll shaft is pulled out, the emulsion explosive medicine roll is removed, and the plastic film at both ends of the emulsion explosive medicine roll is neatly sealed to obtain a reshaped emulsion explosive medicine roll.

[0024] Preferably, the length of the plastic-sealed roll is greater than the length of the damaged emulsion explosive roll by more than 20 cm, and the set number of turns is 4 to 6 layers.

[0025] The beneficial effects of the present invention are:

[0026] 1. The present invention provides a simple treatment method and idea for the treatment of damaged emulsion explosives. The film material of the plastic-sealed roll is easy to obtain. The same outer packaging plastic film as the emulsion explosive roll can be used, and alternatives such as transparent plastic wrap can also be used. The cost is low and safety can be guaranteed without affecting the performance of the emulsion explosive.

[0027] 2. The plastic sealing device has wide applicability. The installation of the plastic sealing roll and the damaged emulsion explosive roll can be adjusted, which can adapt to the reshaping and sealing of emulsion explosives of different specifications. Since the length of the reel can be adjusted, the relative position of the plastic sealing roll and the damaged emulsion explosive roll can be adjusted. In the case of no plastic sealing film of suitable size and width, the outer packaging of the damaged emulsion explosive roll can be fully wound and reshaped in a multi-layer spiral winding manner by adjusting the relative position of the two.

[0028] 3. The damaged emulsion explosive cartridge is assisted by the cartridge transmission rod to transmit the torque of the cartridge shaft, which can effectively prevent the cartridge from twisting and deforming during the reshaping process.

[0029] 4. The plastic sealing device is small and portable, and can be reshaped at the mine blasting construction site to avoid the loss of explosives due to the damage of the on-site explosive rolls. It can greatly save the cost of using mine explosives and reduce the workload of explosives destruction.

[0030] 5. The present invention avoids direct charging of damaged explosives at extremely low cost and workload, eliminates explosive leakage caused by damaged outer packaging of emulsion explosives, avoids charging blockage, reagent leakage, hanging of explosives and the resulting blasting safety problems, ensures the consistency of the blasthole charging structure with the blasting design, and avoids other blasting accidents such as explosion refusal.

[0031] In summary, the damaged emulsion explosive reshaping device and reshaping method provided by the present invention solve the defects of direct use or waste recycling of emulsion explosive rolls with damaged outer packaging. It has a simple structure, is safe and convenient to use, saves the additional cost expenditure caused by damaged explosives in mine blasting, can be promoted and used in various construction occasions using emulsion explosive rolls for blasting, and has extremely high application prospects.

[0042] The technical solution of the present invention is described in more detail below with reference to the accompanying drawings and embodiments:

[0043] Example 1

[0044] like Figure 1-Figure 2 As shown, a damaged emulsion explosive reshaping device comprises a plastic-sealing roll shaft 1-8 and a medicine roll shaft 1-7 arranged in parallel, wherein the plastic-sealing roll shaft 1-8 and the medicine roll shaft 1-7 are detachably arranged on a bracket. The plastic-sealing roll shaft 1-8 and the medicine roll shaft 1-7 are respectively rotatably connected to the bracket, wherein the medicine roll shaft 1-7 also has a gap for placing a damaged emulsion explosive medicine roll 2-2, and the medicine roll shaft 1-7 is respectively provided with clamping members 1-6 on both sides of the gap for fixing the damaged emulsion explosive medicine roll 2-2.

[0045] The clamping member 1-6 can be a spring clamp, and the clamping member 1-6 can be detachably arranged on the medicine roll shaft 1-7 for easy replacement, and the bite force of the clamping member 1-6 is not less than 80kN.

[0046] The bracket includes two pairs of support rods, denoted as plastic sealing roll support rods 1-2 and medicine roll support rods 1-3, which respectively support the plastic sealing roll shaft 1-8 and the medicine roll shaft 1-7. The bottom of each support rod is connected as a whole through the base 1-1.

[0047] In this embodiment, a through hole is provided at the top of each support rod. A rotation gap exists between the plastic wrapping roll shaft 1-8 and the through hole of the plastic wrapping roll support rod 1-2 arranged oppositely, so as to allow the plastic wrapping roll shaft 1-8 to rotate around the rod axis on the bracket; a rotation gap exists between the medicine roll shaft 1-7 and the through hole of the medicine roll support rod 1-3 arranged oppositely, so as to allow the medicine roll shaft 1-7 to rotate around the rod axis on the bracket.

[0048] In this embodiment, the plastic sealing roll shaft 1-8 and the medicine roll shaft 1-7 are both retractable rods, for example, they can be set as sleeve-type retractable rods, and the length can be adjusted manually or electrically. The medicine roll shaft 1-7 has the ability to slide axially on the bracket on either side or both sides of the gap, and the plastic sealing roll shaft 1-8 also has the ability to slide axially on the bracket to facilitate the fixation of the medicine roll shaft 1-7 and the adjustment of the position of the plastic sealing roll. When there is no plastic sealing film 2-3 that matches the length of the damaged emulsion explosive, the plastic sealing film 2-3 can be fully wrapped and reshaped on the outer packaging of the damaged emulsion explosive roll in a multi-layer spiral winding manner by adjusting the relative position of the plastic sealing roll and the damaged emulsion explosive roll.

[0049] Furthermore, a rotating part is arranged between the plastic sealing roll shaft 1-8 and the through hole, and between the medicine roll shaft 1-7 and the through hole. The rotating part is a bearing or other component with similar functions to ensure the self-rotation of the plastic sealing roll shaft 1-8 and the medicine roll shaft 1-7, and can provide locking of the shaft in the upper horizontal direction.

[0050] A turntable 1-4 is also provided at any one end or both ends of the medicine roll shaft 1-7. The turntable 1-4 can be connected to a motor, or a rotating rocker 1-5 can be provided to assist in controlling the rotation of the medicine roll shaft 1-7.

[0051] In this embodiment, the plastic roll support rod 1-2 and the medicine roll support rod 1-3 are fixed to the base 1-1 by welding. The base 1-1 can be made of a rectangular steel plate, or can be replaced by a triangular steel, a square steel pipe, etc. welded into a rectangular shape, so as to reduce the overall weight of the device and better adapt to the working conditions of the undulating terrain of the mine site. The main bodies of the plastic roll support rod 1-2 and the medicine roll support rod 1-3 can be made of round or square steel pipes, and the diameter of the through hole is slightly larger than the plastic roll rotating shaft 1-8 and the medicine roll rotating shaft 1-7.

[0052] The specifications and dimensions of the reshaping device can be adjusted according to actual needs. In a specific embodiment, the length × width × height of the base 1-1 is 85cm × 40cm × 5cm, the diameter of the through hole is 1.7cm, the square section length × width of the support rod is 5cm × 3cm, the height of the plastic roll support rod 1-2 is slightly higher than the medicine roll support rod 1-3, the height of the plastic roll support rod 1-2 is 40cm, and the height of the medicine roll support rod 1-3 is 30cm.

[0053] Example 2

[0054] The two ends of the damaged emulsion explosive roll 2-2 are connected to the roll shaft 1-7 through the clamping member 1-6. The damaged emulsion explosive roll 2-2 is subjected to the torque transmitted by the roll shaft 1-7 during the rotation process, which may easily cause the roll to twist and deform. Therefore, on the basis of Example 1, a roll shaft transmission rod 1-10 is further provided.

[0055] refer to Figure 3-Figure 5 The drug roll shaft transmission rod 1-10 is arranged parallel to the drug roll shaft 1-7, and the two ends of the drug roll shaft transmission rod 1-10 are respectively connected to the drug roll shafts 1-7 on both sides of the gap through the transmission bracket 1-9. The drug roll shaft transmission rod 1-10 can keep the drug roll shafts 1-7 on both sides of the gap rotating synchronously. The drug roll transmission rod 1-10 replaces the damaged emulsion explosive drug roll 2-2 to transmit torque, thereby avoiding the torsional deformation of the damaged emulsion explosive drug roll 2-2 during the reshaping process.

[0056] The transmission bracket 1-9 is detachably connected to the medicine roll shaft 1-7 through a quick-change socket 1-11, which is a threaded interface or a slot interface, etc., so as to facilitate the disassembly and replacement of the transmission bracket 1-9 of different heights, adapt to the diameter size of the damaged emulsion explosive medicine roll 2-2 with different cross-sectional sizes, and ensure that the medicine roll shaft transmission rod 1-10 connected thereto can be closely attached to the side wall of the outer packaging of the medicine roll after the damaged emulsion explosive medicine roll 2-2 is clamped and fixed by the end. The transmission bracket 1-9 can also be set as a telescopic bracket, and the telescopic transmission bracket 1-9 can be used to more quickly adjust the medicine roll shaft transmission rod 1-10 to be closely attached to the outer surface of the damaged emulsion explosive medicine roll 2-2.

[0057] The drug roll shaft transmission rod 1-10 rotates with the damaged emulsion explosive drug roll 2-2 and is wrapped in the plastic film 2-3. After the remodeling is completed, the drug roll shaft transmission rod 1-10 is pulled out from one end of the drug roll to separate the drug roll shaft transmission rod 1-10 and the remodeled damaged emulsion explosive drug roll 2-2. The gap generated after the drug roll shaft transmission rod 1-10 is pulled out can be filled by squeezing the emulsion explosive, and then the plastic film 2-3 at both ends of the emulsion explosive drug roll is tidied and sealed, which will not affect the performance of the remodeled emulsion explosive drug roll.

[0058] refer to Figure 6-Figure 7 In order to further improve the torque transmission effect of the cartridge shaft transmission rod 1-10 on the damaged emulsion explosive cartridge 2-2, two groups of cartridge shaft transmission rods 1-10 are symmetrically arranged at an interval of 180° outside the damaged emulsion explosive cartridge.

[0059] The shape of the drug roll shaft transmission rod 1-10 can be set to fit the concave surface of the outer surface of the damaged emulsion explosive drug roll 2-2 to reduce the gap formed in the repeated wrapping process of the plastic sealing film 2-3.

[0060] Example 3

[0061] The present invention also provides a method for reshaping a damaged emulsion explosive reshaping device as described above, comprising the following steps:

[0062] S1. Before the remolding operation begins, check whether the production date and hazard and transportation signs of the damaged emulsion explosive volume 2-2 meet the specifications for continued use. If the damaged emulsion explosive 2-2 has expired or the signs are unclear, it cannot be plastic-sealed and used any more and must be transferred to the explosives destruction site for unified destruction.

[0063] S2. The sealing rings at both ends of the screened damaged emulsion explosive roll 2-2 are fixedly connected to the clamping member 1-6 on the roll shaft 1-7, and the transmission bracket 1-9 is adjusted so that the roll shaft transmission rod 1-10 fits the outer surface of the damaged emulsion explosive roll 2-2, so that the roll shaft 1-7, the damaged emulsion explosive roll 2-2 and the roll shaft transmission rod 1-10 form a rotating whole;

[0064] S3. Select a plastic sealing roll 2-1 of a size corresponding to the damaged emulsion explosive roll 2-2, install it on the plastic sealing roll rotating shaft 1-8, pull the end of the plastic sealing film 2-3 of the plastic sealing roll 2-1 to the surface of the damaged emulsion explosive roll 2-2 for bonding and fixing, then rotate the roll rotating shaft 1-7 to automatically wind the plastic sealing film 2-3 on the plastic sealing roll 2-1 to the surface of the damaged emulsion explosive roll 2-2 and the roll transmission rod 1-10.

[0065] S4. After the surface of the damaged emulsion explosive roll 2-2 is completely wrapped with the plastic film 2-3, the reshaping is completed. After ensuring that the damaged part of the damaged emulsion explosive roll 2-2 no longer leaks, cut the plastic film 2-3, and bond the broken end of the plastic film 2-3 to the surface of the roll; extract the roll shaft transmission rods 1-10 from both ends of the reshaped damaged emulsion explosive roll 2-2, remove the reshaped damaged emulsion explosive roll 2-2 from the roll shaft 1-7, tidy up the gap formed by extracting the roll shaft transmission rod 1-10, and neatly seal the plastic film 2-3 at both ends of the roll to obtain a reshaped emulsion explosive roll.

[0066] In this method, the plastic sealing roll 2-1 is wound with a film made of polyethylene or polyvinyl chloride. The width of the plastic sealing film 2-3 of the plastic sealing roll 2-1 is selected according to the length of the damaged emulsion explosive roll, and its length should be about 20 cm greater than the length of the roll, so that after the wrapping is completed, the end face of the damaged emulsion explosive roll 2-2 is also protected. If there is no plastic sealing roll 2-1 of suitable size at the construction site, a plastic sealing film 2-3 with a width less than the length of the damaged emulsion explosive roll 2-2 can be used to spirally wrap the damaged emulsion explosive roll 2-2 by adjusting the plastic sealing roll 2-1. The plastic sealing film 2-3 should be wrapped on the outer packaging surface of the damaged emulsion explosive roll 2-2 in 4 to 6 layers to obtain a better damage repair effect.

[0067] The plastic sealing film 2-3 can be bonded to the surface of the damaged emulsion explosive roll 2-2 by adhesive tape. During bonding, both the cylindrical surface and the end surface of the damaged emulsion explosive roll 2-2 need to be bonded to prevent the damaged emulsion explosive roll 2-2 from falling off from the inside of the reshaped and wrapped plastic sealing film 2-3.

[0068] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
