[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] The specific technical features described in the various embodiments in the detailed implementation can be combined in various ways without contradiction. For example, different implementation methods can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

[0028] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0029] Additionally, it should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate any similarity or connection between them. It should be understood that the directional descriptions such as "above," "below," "inside," and "outside" refer to the orientation under normal use conditions.

[0030] In some embodiments, such as Figure 1As shown, the energetic material destruction device includes: an incineration unit 100, a continuous feeding system 200, and a desensitizing liquid seal device 300. The incineration unit 100 has an incineration chamber 110 for energetic materials, which can be burned in the incineration chamber 110 after entering it to achieve the treatment of energetic materials; the continuous feeding system 200 is used to transport energetic materials from a location away from the incineration chamber 110 to the incineration chamber 110. It should be noted that the continuous feeding system 200 can transport energetic materials in any way. For example, the continuous feeding system 200 includes a tracked conveyor structure, which can transport energetic materials carried on the conveyor belt to the incineration chamber 110 by the movement of the tracked conveyor structure. For example, the continuous feeding system 200 includes multiple rollers arranged in parallel, which can transport energetic materials carried on the rollers to the incineration chamber 110 by the rotation of the rollers. For example, the continuous feeding system 200 includes an inclined platform with an inclined plane, which allows the energetic materials to slide into the incineration chamber 110 along the inclined plane under the action of their own gravity.

[0031] The energetic material may be accidentally ignited during its transmission on the continuous feeding system 200. To reduce this risk, the sensitivity of the energetic material needs to be reduced. Therefore, the energetic material destruction device also includes a sensitivity-reducing liquid seal device 300, which contains a sensitivity-reducing liquid. The energetic material and at least part of the continuous feeding system 200 are immersed in the sensitivity-reducing liquid. By immersing the energetic material in the sensitivity-reducing liquid, the sensitivity of the energetic material can be reduced, making it less flammable, thereby reducing the risk of combustion and explosion of the energetic material during transmission. The sensitivity-reducing liquid can be water or an aqueous solution of sodium chloride.

[0032] Meanwhile, the continuous feeding system 200 extends into the combustion chamber 110 through the opening of the combustion device 100. By immersing the continuous feeding system 200 and the energetic material in the desensitizing liquid, the opening can be sealed by the desensitizing liquid, thereby reducing the risk of gas leakage between the gas in the combustion chamber 110 and the outside air through the opening.

[0033] This utility model provides a device for destroying energetic materials. The device includes an incineration unit with an incineration chamber for burning energetic materials, and a continuous feeding system extending into the incineration chamber from a distance to automatically transfer energetic materials into the incineration chamber. The device also includes a desensitizing liquid seal device for containing desensitizing liquid. The energetic materials carried by the continuous feeding system, as well as at least a portion of the continuous feeding system, are immersed in the desensitizing liquid. The energetic materials immersed in the desensitizing liquid have lower sensitivity, making them less prone to accidental combustion and thus improving the safety of energetic material processing. Furthermore, through automatic transport, human interference is eliminated during transport, and personnel involvement is minimized, further improving the safety of energetic material processing.

[0034] In some embodiments, such as Figure 2 As shown, the continuous feeding system 200 includes a conveyor belt 220 and an enclosing wall 230. The enclosing wall 230 is located below the conveyor belt 220 and encloses a desensitization chamber 310 with a top opening. The conveyor belt 220 can extend into the desensitization chamber 310 through the top opening, thereby immersing the conveyor belt 220 and the energetic material carried on the conveyor belt 220 in the desensitization liquid, thus reducing the sensitivity of the energetic material and making it less prone to combustion and explosion, further improving the safety of the energetic material processing. Optionally, the end of the enclosing wall 230 has an opening, through which the conveyor belt 220 and the energetic material can pass through the enclosing wall 230 and fall into the incineration chamber 110. The conveyor belt 220 can also be conveyed obliquely upward to the outside of the enclosing wall 230, so that the energetic material can fall into the incineration chamber 110. The conveyor belt 220 can be any type of conveyor belt, such as a belt drive belt or a tracked conveyor belt.

[0035] Optionally, the continuous feeding system 200 also includes a drive structure for driving the conveyor belt to move along its own extension direction. For example, the drive structure is connected to the drive pulley of the transmission belt to drive the conveyor belt to move along its own direction, thereby moving the energetic material. The incineration device 100 is also equipped with a first pressure sensor for acquiring the pressure inside the incineration chamber 110. The speed at which the drive structure drives the transmission belt is negatively correlated with this pressure. In other words, the higher the pressure inside the incineration chamber 110, the slower the drive structure drives the transmission belt, thus slowing down the rate at which the energetic material enters the incineration chamber 110 for combustion, thereby reducing the combustion rate of the incineration chamber 110. The rate at which waste is generated by combustion within the combustion chamber 10 decreases the pressure within the combustion chamber 110, thereby maintaining a dynamic balance in the pressure within the combustion chamber 110. Alternatively, the incineration device 100 may also include a first temperature sensor, which is used to acquire the temperature within the combustion chamber. The speed at which the drive structure drives the transmission belt is negatively correlated with this temperature. This can be understood as follows: the higher the temperature within the combustion chamber 110, the slower the drive structure drives the transmission belt, thus slowing down the rate at which energetic materials enter the combustion chamber 110 for combustion. This reduces the rate at which heat is generated by combustion within the combustion chamber 110, thereby reducing the temperature within the combustion chamber 110 and maintaining a dynamic balance in the temperature within the combustion chamber 110.

[0036] In some embodiments, such as Figure 3 As shown, the insensitivity-reducing liquid sealing device 300 also includes a liquid storage component 330, a liquid delivery pipeline 340, and a liquid pump 350. The liquid storage component 330 has a liquid storage chamber 331 for storing insensitivity-reducing liquid. The liquid delivery pipeline 340 connects the liquid storage chamber 331 and the insensitivity-reducing chamber 310. The liquid pump 350 is connected to the liquid delivery pipeline 340 and is used to drive the insensitivity-reducing liquid in the liquid storage chamber 331 into the insensitivity-reducing chamber 310. It can be understood that the insensitivity-reducing liquid in the insensitivity-reducing chamber 310 will inevitably be consumed. In order to make the insensitivity-reducing chamber 310 have reliable insensitivity-reducing and liquid sealing effects, it is necessary to adaptively replenish the insensitivity-reducing liquid in the liquid storage chamber 331 into the insensitivity-reducing chamber 310 by the liquid pump 350.

[0037] In some embodiments, such as Figure 4 As shown, one end of the conveyor belt 210 located inside the incineration chamber 110 is higher than the other end opposite to it. This can be understood as the conveyor belt 210 extending obliquely upward in a direction away from and towards the incineration chamber 110. While transporting energetic materials into the incineration chamber 110, the desensitizing liquid carried by the conveyor belt 210 can slide down under its own gravity, thereby reducing the amount of desensitizing liquid carried away from the desensitizing cavity 310 by the conveyor belt 210 and reducing the consumption of desensitizing liquid in the desensitizing cavity 310.

[0038] In some embodiments, such as Figure 5As shown, the incineration chamber 110 includes a combustion station 111 and an ignition structure 112. Energetic material detached from the end of the conveyor belt 210 can fall onto the combustion station 111. The bottom of the combustion station 111 is provided with energy-absorbing buffer material to reduce the impact force generated by the falling energetic material, thereby reducing the risk of accidental ignition under this impact force. This energy-absorbing buffer material can be, for example, buffer sand. The ignition structure 112 is used to ignite the energetic material at the combustion station. Exemplarily, the ignition structure 112 includes a laser ignition structure and a gas ignition structure, igniting the energetic material through the flame of laser or gas combustion. Optionally, simultaneously providing both a laser ignition structure and a gas ignition structure allows the other ignition structure to be activated if one ignition method fails to ignite the energetic material, thereby improving the ignition success rate of the energetic material. Optionally, the combustion station 111 can be understood as any structure capable of placing energetic material and withstanding the high temperatures during the combustion process of the energetic material. Exemplarily, the combustion station 111 is a high-temperature resistant ceramic bowl.

[0039] The energy-containing material destruction device also includes a guide member 400, which is fixed to the end of the continuous feeding system 200 located in the incineration chamber 110. The guide member 400 extends from this end to the combustion station 111. It can be understood that the guide member 400 extends obliquely downward from the end of the continuous feeding system 200 to the combustion station 111, so that the energy-containing material does not fall directly to the combustion station 111 through free fall, but slides down along the guide member 400 to the combustion station 111, thereby further reducing the impact force generated when the energy-containing material falls, and further reducing the risk of the energy-containing material igniting and exploding under the action of the impact force.

[0040] In some embodiments, such as Figure 6 As shown, the guide member 400 has a first reflux hole 410 on the surface for contacting the energetic material. This can be understood as follows: under the action of the continuous feeding system 200, a portion of the desensitizing fluid moves to the guide member 400 along with the energetic material, thereby allowing the energetic material to fall along with a portion of the desensitizing fluid. Figure 5 The combustion station in the middle, so that the energetic material still maintains a low sensitivity during the fall, further reducing the risk of the energetic material being accidentally ignited. At the same time, the sensitivity-reducing liquid seal device 300 also includes a first return pipe 360, which connects the first return hole 410 and the sensitivity-reducing cavity 310, so that part of the sensitivity-reducing liquid flowing to the guide member 400 can flow back into the sensitivity-reducing cavity 310 through the first return hole 410, reducing the consumption of sensitivity-reducing liquid in the sensitivity-reducing cavity 310, and also maintaining a certain liquid level in the sensitivity-reducing cavity, so that the sensitivity-reducing liquid can reliably immerse the energetic material carried by the continuous feeding system 200.

[0041] In some embodiments, such as Figure 7As shown, the combustion station 111 has a second return hole 113 located at the bottom of the combustion station 111. The combustion station 111 has a leakage structure that allows the desensitizing liquid to pass through. A filter structure is provided between the leakage structure and the second return hole 113. The filter structure can be, for example, a filter layer, a fine sand layer, or a pebble layer. The leakage structure can be a machined leakage hole or the pores of the porous material itself. The desensitizing liquid sealing device 300 also includes a second return pipe 370, which connects the second return hole 113 and the desensitizing cavity 310. This allows the desensitizing liquid falling into the combustion station 111 to return to the desensitizing cavity 310 after filtration, reducing the consumption of the desensitizing liquid in the desensitizing cavity 310 and maintaining a certain liquid level in the desensitizing cavity, so that the desensitizing liquid can reliably submerge the energetic material carried by the continuous feeding system 200.

[0042] In some embodiments, such as Figure 8 As shown, the energy-containing material destruction device also includes an exhaust gas treatment device 500, which is connected to the incineration chamber 110 and is used to treat the exhaust gas after the energy-containing material is burned. For example, the exhaust gas treatment device 500 is used to desulfurize or neutralize the exhaust gas, thereby reducing the pollution of the exhaust gas to the environment.

[0043] In some embodiments, such as Figure 8As shown, an exhaust device 510 is provided between the incineration chamber 110 and the waste gas treatment device 500. The exhaust device 510 is used to control the speed at which waste gas enters the waste gas treatment device 500. The larger the exhaust flow rate of the exhaust device 510, the faster the waste gas enters the waste gas treatment device 500. The smaller the exhaust flow rate of the exhaust device 510, the slower the waste gas enters the waste gas treatment device 500. The exhaust device 510 can be an exhaust valve, and the exhaust flow rate can be adjusted by the opening degree of the exhaust valve. The exhaust device 510 can also be a ventilation structure inside the waste gas treatment device 500, and the exhaust flow rate can be adjusted by controlling the rotation speed of the ventilation structure. The exhaust flow rate of the exhaust device 510 can control the temperature or pressure inside the combustion chamber 510. Optionally, the incineration device also includes a second temperature sensor to acquire the temperature inside the combustion chamber 110. The exhaust flow rate of the exhaust device is positively correlated with this temperature; that is, the higher the temperature inside the combustion chamber 110, the greater the exhaust flow rate of the exhaust device. This allows the exhaust gas to enter the waste gas treatment device 500 more quickly, thereby bringing more heat into the waste gas treatment device 500, which in turn lowers the temperature inside the combustion chamber 110 and maintains a dynamic balance in the temperature inside the combustion chamber 110. Optionally, the incineration device also includes a second pressure sensor to acquire the pressure inside the combustion chamber 110. The exhaust flow rate of the exhaust device is positively correlated with this pressure; that is, the higher the pressure inside the combustion chamber 110, the greater the exhaust flow rate of the exhaust device. This allows the exhaust gas to enter the waste gas treatment device 500 more quickly and lowers the pressure inside the combustion chamber 110, thereby maintaining a dynamic balance in the pressure inside the combustion chamber 110.

[0044] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
