Description

Technical Field

[0001] This utility model belongs to the technical field of coarse-particle-size explosive feeding devices, specifically a device for accurately feeding coarse-particle-size explosives. Background Technology

[0002] Currently, on automated production lines for coarse-grained explosives, after accurate metering, the coarse-grained explosives enter a discharging device. This device then inverts the explosives into a feeding hopper, where they are drawn into the reaction vessel under gravity. However, if wet coarse-grained explosives are used, they frequently adhere to the discharging device and feeding hopper, requiring manual on-site cleaning. This is not only inconvenient but, if forgotten, can lead to an imbalance in the proportion of coarse-grained explosives in the reaction, potentially causing an explosion. This poses a significant safety hazard and exposes personnel to a dangerous working environment multiple times.

[0003] Therefore, there is an urgent need for a device for accurately feeding coarse-grained explosives to solve the problem that in automated coarse-grained explosive production lines, the accurately metered coarse-grained explosives cannot all enter the reactor, thereby reducing the frequency of personnel exposure to hazardous working environments and a series of safety hazards caused by the imbalance of the proportion of coarse-grained explosives in the reaction due to inadequate feeding. Utility Model Content

[0004] The purpose of this invention is to provide an accurate feeding device for coarse-grained explosives, which solves the problem that in current automated coarse-grained explosive production lines, the accurately metered coarse-grained explosives cannot be fully added to the reaction vessel. This invention completely solves the problem that existing feeding devices still require operators to enter the site for cleanup after adding coarse-grained explosives, reducing the safety hazards caused by the imbalance of the reaction ratio of coarse-grained explosives.

[0005] This utility model is achieved using the following technical solution:

[0006] A device for accurately feeding coarse-particle-size explosives includes a discharging device, a feeding bin, and a solvent tank. It also includes a solvent pipe, one end of which is connected to a tee. The solvent pipe is equipped with a flow meter. The tee is also connected to a straight pipe (first and second). The first straight pipe extends into the discharging device, and the second straight pipe extends into the feeding bin. The first straight pipe is connected to a nozzle, and the second straight pipe is also connected to a nozzle. The other end of the solvent pipe is connected to the solvent tank.

[0007] In application, the metered coarse-grained explosive is loaded into the discharge device. The device, tilted by a tipping mechanism, allows the explosive to slowly flow into the feeding hopper. Under gravity, the explosive flows slowly into the reactor. The solvent supply is then activated, and the solvent flows out through a nozzle or spray nozzle. This nozzle or spray nozzle washes away the explosive adhering to the discharge device and the feeding hopper. After washing, the solvent flowing from the nozzle or spray nozzle enters the reactor along with the explosive. The amount of solvent used is metered and included in the total solvent added to the reactor, ensuring a consistent proportion of explosive in the reaction.

[0008] More preferably, the solvent tube is a 316L type, and the solvent tube is connected to a static-dissipating wire.

[0009] More preferably, the solvent tube is arranged at an angle to reduce the amount of solvent retained in the solvent tube.

[0010] More preferably, the first and second straight pipes are telescopic pipes, which can be retracted during the non-rinsing stage to prevent them from hindering the flow of coarse-diameter explosives into the reactor.

[0011] In a further preferred embodiment, the feeding hopper is connected to an external electrostatic discharge line, so that the static electricity generated during the flow of coarse-particle explosives into the reactor can be promptly conducted away through the electrostatic discharge line.

[0012] More preferably, the flow meter is positioned near the tee on the solvent tube.

[0013] Preferably, the material pouring device and the feeding hopper are equipped with cameras, which transmit images back to the control center for easy observation of whether the material pouring device and the feeding hopper have been cleaned.

[0014] This device has a reasonable and simple structure, is safe and reliable, and has high potential for widespread application. Attached Figure Description

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0022] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] A device for accurately feeding coarse-diameter explosives includes a discharging device 1, a feeding bin 2, and a solvent tank. It also includes a solvent pipe 4, one end of which is connected to a tee. A flow meter 6 is installed on the solvent pipe 4 to track the amount of solvent used for rinsing the coarse-diameter explosives, ensuring a constant total amount of reaction solvent. The tee also connects to two straight pipes: one extending into the discharging device 1 and the other into the feeding bin 2. Both straight pipes are connected to a nozzle or spray head 5. The other end of the solvent pipe 4 is connected to the solvent tank. The nozzle or spray head 5 sprays a water jet.

[0024] It should be noted here that industry professionals can be certain that the solvent will not adhere to the dispensing device 1 and the feeding bin 2. The solvent remaining in the solvent pipe 4 is a systematic error and can be avoided by calibrating the flow meter 6.

[0025] Solvent tube 4 is a 316L model. Solvent tube 4 is connected to an electrostatic conductive wire 3. Solvent tube 4 is arranged at an angle. Flow meter 6 is set near the tee of solvent tube 4. Solvent tube 4 is installed near the reaction vessel, pouring device 1 and feeding bin 2 by means of a bracket.

[0026] Straight pipe 1 and straight pipe 2 are telescopic pipes, and the feeding hopper 2 is connected to an external static-conducting wire 3.

[0027] The working principle is as follows: the feeding device 1 is used to hold the accurately measured coarse-diameter explosives. The feeding device 1 is tilted by the existing turning mechanism, and the coarse-diameter explosives are slowly put into the feeding bin 2. When the coarse-diameter explosives enter the feeding bin 2 and the reaction vessel, they will stick to the feeding device 1 and the feeding bin 2 due to friction.

[0028] When only coarse-grained explosive particles remain in the discharge device 1 and the feeding bin 2, the solvent delivery is activated. The solvent is delivered through the solvent pipe 4 and flows out from the nozzle or spray nozzle 5. The solvent input into the solvent pipe 4 is the same as that in the reaction vessel.

[0029] The solvent flows out from the nozzle or spray nozzle 5 to wash the coarse-sized explosives adhering to the discharge device 1 and the feeding bin 2. After washing, the solvent and coarse-sized explosives enter the reactor together. The solvent used for washing is measured by the flow meter 6 on the solvent pipe 4 and calculated together with the solvent in the reactor to ensure that the proportion of coarse-sized explosives in the reaction is consistent.

[0030] In Example 2, the material pouring device 1 and the feeding bin 2 are equipped with cameras, which transmit images back to the control center.

[0031] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and all should be covered by the protection scope of the claims.
