Description

Technical Field

[0001] The utility model relates to the technical field of explosive combustion auxiliary devices, and specifically to an explosive combustion auxiliary device. Background Art

[0002] Explosive destruction technology is a method of safely handling expired explosives. Traditional destruction technologies include detonation, incineration, chemical decomposition, etc. The incineration method requires a specially set up incinerator body to burn the explosives in the incinerator body. The incinerator body is about 3-4m high. Before incineration, the explosives need to be placed into the incinerator body through packaging bags, and then ignited and burned.

[0003] The incinerator body in the prior art has the following problems: although a tray is welded inside the incinerator body to support the packaging bag and the explosives therein, the substances produced after ignition, such as powder, cannot be discharged smoothly from the tray, affecting subsequent processing. At the same time, the bottom surface of most trays is flat, resulting in uneven distribution of the explosives received, which may lead to insufficient ignition, resulting in the need for secondary ignition, and the need for repeated incineration operations, which reduces the processing efficiency. Utility Model Content

[0004] The utility model provides an explosive combustion auxiliary device, which solves the problem in the related art that the bottom surface of the supporting tray in the incinerator body is mostly flat, resulting in uneven distribution of the explosives received and the possibility of failure to smoothly ignite the explosives to be processed.

[0005] The technical solution of the utility model is as follows:

[0006] An explosive combustion auxiliary device for supporting explosives, comprising:

[0007] A supporting body, wherein the bottom of the supporting body has a plurality of first leakage holes, the plurality of first leakage holes are arranged circumferentially, and the cross-sectional area of ​​the supporting body gradually decreases from the top to the bottom, and a material receiving ignition zone is formed between the plurality of first leakage holes.

[0008] As a further technical solution, the bottom of the supporting body further has a second leakage hole, and a plurality of the first leakage holes are arranged along the circumference of the second leakage hole.

[0009] As a further technical solution, the supporting body is in a frustum shape, the side wall of the supporting body has a plurality of the first leakage holes, the bottom center of the supporting body has the second leakage hole, and the cross-sectional area of ​​the supporting body gradually increases from close to to far away from the second leakage hole.

[0010] As a further technical solution, the material receiving and ignition zone is formed between a plurality of the first leakage holes and the second leakage holes.

[0011] As a further technical solution, the supporting body is conical, the supporting body has a conical end, and a plurality of the first leakage holes are arranged along the circumference of the conical end.

[0012] As a further technical solution, it also includes:

[0013] An auxiliary ignition device is arranged on the supporting body and is used to burn the explosive supported by the supporting body.

[0014] As a further technical solution, the auxiliary ignition device is an ignition tube, the auxiliary ignition device passes through the supporting body, the auxiliary ignition device has an ignition port, and the ignition port faces the material ignition area.

[0015] The working principle and beneficial effects of the utility model are:

[0016] In the utility model, most of the traditional supporting trays are cylindrical, and the explosives fed may be unevenly arranged on the supporting tray, resulting in the ignition action cannot be carried out smoothly, and may even fail to ignite. Changing the ignition angle on this basis is prone to safety accidents, and the cost of change is high, so the cross-sectional area of ​​the supporting body is set to change gradually, gradually decreasing from top to bottom, that is, the material receiving and ignition zone is the end with a small cross-sectional area, and the end with a large cross-sectional area faces the feed port at the top of the incinerator body, so that the packaging bag and the explosives therein are received in the material receiving and ignition zone. The explosives can be stably gathered, which is convenient for the ignition operation and avoids uneven distribution of explosives and failure to ignite.

[0017] Furthermore, a plurality of first leakage holes are arranged circumferentially on the supporting body, so that the powder produced by the explosion can be smoothly discharged from the supporting body through the first leakage holes in the material receiving and ignition zone, and finally discharged from the incinerator body. The formation of the material receiving and ignition zone provides a stable and controlled combustion space for the explosive. By controlling the temperature and oxygen supply in this area, the combustion conditions can be further optimized to ensure a stable and efficient combustion process, reduce the generation of pollutants, and meet environmental protection requirements.

[0018] The overall structural design is relatively simple, which facilitates regular inspection and cleaning of the supporting body to ensure long-term stable operation of the device. At the same time, the intuitive combustion area division and adjustment mechanism enable operators to more easily monitor and control the combustion process. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Reference Figure 1~Figure 3 , which is the first embodiment of the utility model, proposes an explosive combustion auxiliary device for supporting explosives, comprising:

[0029] The supporting body 1 has a plurality of first leakage holes 101 at the bottom thereof, the plurality of first leakage holes 101 are arranged circumferentially, and the cross-sectional area of ​​the supporting body 1 gradually decreases from the top to the bottom, and a material receiving ignition zone 102 is formed between the plurality of first leakage holes 101.

[0030] In this embodiment, Figures 1 to 3 As shown, most of the traditional support trays are cylindrical, and the explosives fed may be unevenly arranged on the support tray, resulting in the ignition action not being able to proceed smoothly, and may even fail to ignite. Changing the ignition angle on this basis is prone to safety accidents, and the cost of change is high, so the cross-sectional area of ​​the supporting body 1 is set to change gradually, gradually decreasing from top to bottom, that is, the material receiving and ignition zone 102 is the end with a small cross-sectional area, and the end with a large cross-sectional area faces the feed port at the top of the incinerator body, so that the packaging bag and the explosives therein are received in the material receiving and ignition zone 102, the explosives can be stably gathered, the ignition operation is convenient, and uneven distribution of explosives and failure to ignite are avoided.

[0031] Furthermore, a plurality of first leakage holes 101 are arranged circumferentially on the supporting body 1, so that the powder produced by the explosion can be smoothly discharged from the supporting body 1 through the first leakage holes 101 in the material receiving and ignition zone 102, and finally discharged from the incinerator body. The formation of the material receiving and ignition zone 102 provides a stable and controlled combustion space for the explosive. By controlling the temperature and oxygen supply in this area, the combustion conditions can be further optimized to ensure a stable and efficient combustion process, reduce the generation of pollutants, and meet environmental protection requirements.

[0032] The overall structural design is relatively simple, which facilitates regular inspection and cleaning of the supporting body 1 to ensure long-term stable operation of the device. At the same time, the intuitive combustion area division and adjustment mechanism enable operators to more easily monitor and control the combustion process.

[0033] Furthermore, the bottom of the supporting body 1 also has a second leakage hole 103 , and a plurality of the first leakage holes 101 are arranged around the circumference of the second leakage hole 103 .

[0034] In this embodiment, Figures 1 to 3 As shown, in order to further improve the processing efficiency of the powder generated by the explosion and make it quickly separate from the supporting body 1, a second leakage hole 103 is opened at the bottom thereof, and a plurality of first leakage holes 101 are arranged in a circle around the second leakage hole 103 to more comprehensively cover the entire supporting and ignition cavity and quickly discharge all the powder.

[0035] Furthermore, the supporting body 1 is in a frustum shape, the side wall of the supporting body 1 has a plurality of the first leakage holes 101, the bottom center of the supporting body 1 has the second leakage hole 103, and the cross-sectional area of ​​the supporting body 1 gradually increases from close to to far from the second leakage hole 103.

[0036] Furthermore, the material receiving and ignition zone 102 is formed between a plurality of the first material leakage holes 101 and the second material leakage holes 103 .

[0037] In this embodiment, Figure 1 , 2 As shown, the first specific implementation mode of the supporting body 1 is defined as a frustum shape with the opening toward the top of the furnace body, that is, the cross-sectional area of ​​the supporting body 1 gradually increases from the second leakage hole 103 close to the bottom to the second leakage hole 103 far away from the bottom, which can stably gather the explosives in the receiving and ignition cavity, and is convenient for the ignition operation. The bottom surface of the frustum is also convenient for arranging a plurality of second leakage holes 103 in the center of the first leakage holes 101, and defines the arrangement positions of the first leakage holes 101 and the second leakage holes 103. The first leakage hole 101 is provided with a plurality of first leakage holes 101 and second leakage holes 103 along the side wall. The receiving and ignition area 102 between them can more comprehensively receive the packaging bag and the explosives therein. The function of the packaging bag is to prevent the explosives from being discharged directly from the leakage holes, and the powder produced by the explosion can be quickly discharged from the two leakage holes.

[0038] Furthermore, the supporting body 1 is conical, and has a conical end 104 , and a plurality of the first leakage holes 101 are arranged along the circumference of the conical end 104 .

[0039] In this embodiment, Figure 3 As shown, a second specific implementation method of the supporting body 1 is defined as a conical shape with the opening facing the top of the furnace body and the conical end 104 away from the top of the furnace body, so as to facilitate the gathering of explosives in the material receiving and ignition cavity formed by a plurality of circumferentially arranged first leakage holes 101 and implement the ignition operation. The structure is simple and convenient for early production and later maintenance.

[0040] Furthermore, it also includes:

[0041] An auxiliary ignition device 2 is provided on the supporting body 1 and is used for burning the explosive supported by the supporting body 1 .

[0042] Furthermore, the auxiliary ignition device 2 is an ignition tube 201 , and the auxiliary ignition device 2 passes through the supporting body 1 . The auxiliary ignition device 2 has an ignition port 202 , and the ignition port 202 faces the material ignition zone 102 .

[0043] In this embodiment, Figure 1As shown, the laser ignition device 2 performs specific ignition operations and is arranged on the top of the furnace body. On the one hand, it ensures that the laser can smoothly hit the material ignition area 102. On the other hand, with the help of the height of the furnace body, it prevents the exploding powder from moving upward and impacting the laser ignition device 2, causing damage to the device; further, several laser ignition devices 2 can be installed and arranged in a circle for better ignition effect. At the same time, monitoring equipment can be arranged at intervals to achieve the purpose of monitoring the ignition effect, to determine whether to emit the laser again or use the auxiliary ignition device 2 on the inner wall of the furnace body for auxiliary ignition. Therefore, in order to ensure the effectiveness of the auxiliary ignition device 2, it is arranged on the supporting body 1.

[0044] Specifically, the auxiliary ignition device 2 is implemented in the form of an ignition tube 201. The ignition tube 201 passes through the supporting body 1, and its ignition port 202 is aligned with the material ignition cavity, that is, the inner wall of the supporting body 1. When the monitoring equipment on the top finds that the ignition is not complete, the ignition tube 201 can be controlled to spray fire and ignite the explosive again.
