Description

Technical Field

[0001] This invention relates to the field of feeding device technology, and in particular to a liquid explosive feeding device. Background Technology

[0002] In the production of mixed explosives and the injection of explosives into projectiles, the precise metering and safe feeding of liquid explosives are crucial steps. Mixed explosives are made by melting and mixing various explosive components. The melted and mixed liquid explosives need to be transported and metered through specific devices to ensure the accuracy of the injected amount. Therefore, the liquid explosive feeding device is a key piece of equipment in the production process.

[0003] However, existing feeding devices mostly use simple valve structures to control the amount of explosive. However, when liquid explosives are transported in a valve structure, the temperature of the liquid explosives will drop. As the temperature drops, the fluidity of the liquid explosives will also change, which will directly affect the metering accuracy and feeding stability of the liquid explosives, thus reducing the accuracy of the amount of ammunition injected. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a liquid explosive feeding device.

[0005] This invention provides a liquid explosive feeding device, comprising an outer shell and an inner shell disposed within the outer shell; the inner shell has a liquid explosive chamber, and an inlet and an outlet are respectively provided at opposite ends of the inner shell, both of which are connected to and extend out of the outer shell; a valve assembly is connected to the inlet, and a metering assembly capable of measuring the flow rate of the liquid explosive is connected to the outlet; an insulation cavity covering the inner shell is provided between the outer shell and the inner shell, and an inlet and an outlet communicating with the insulation cavity are respectively provided at opposite ends of the outer shell, the inlet being able to communicate with an external heat source.

[0006] Optionally, the inlet and outlet are located on opposite sides of the inner shell in a first direction, and the inlet and outlet are located on opposite sides of the outer shell in a second direction, with the first and second directions being perpendicular.

[0007] Optionally, the first direction is the vertical direction, and the second direction is the horizontal direction.

[0008] Optionally, the metering component is a flow meter, and the flow meter and the drug outlet of the inner shell are sealed together by a first sealing ring.

[0009] Optionally, the outlet of the flow meter is connected to an electronic valve that is electrically connected to the controller, and the outlet of the electronic valve is connected to a flexible hose.

[0010] Optionally, the external heat source is a hot water system capable of outputting hot water, with the output temperature of the hot water being greater than 20℃ and less than 70℃.

[0011] Optionally, the valve assembly includes a valve body and a drive assembly capable of opening and closing the valve body, wherein the valve body and the inlet are sealed together by a second sealing ring.

[0012] Optionally, a connecting flange is also included, wherein the inlet end of the valve body and the connecting flange are sealed together by a third sealing ring, and bolts are installed on the connecting flange.

[0013] Optionally, the drive component is a motor.

[0014] Optionally, the valve body is a plug valve.

[0015] The technical solution provided by the embodiments of the present invention has the following advantages compared with the prior art: 1. By setting an outer shell and an inner shell, an insulation cavity can be formed between the outer shell and the inner shell. The inlet of the outer shell can be connected to an external heat source, so that the insulation cavity can maintain a suitable temperature. Therefore, the feeding device of the present invention can avoid the liquid explosive from changing its fluidity due to temperature changes during the transportation process, and can ensure that the liquid explosive is always in the state required by the process, thus providing a guarantee for subsequent metering and feeding.

[0016] 2. By connecting a metering component to the outlet, the metering component can directly measure the flow rate of the liquid explosive. The metering component is directly connected to the outlet of the inner shell, which will reduce the loss and interference of the liquid explosive during the transmission process and make the metering results more accurate. At the same time, the valve component connected to the inlet can flexibly control the amount of explosive fed and can cooperate with the metering component to further improve the accuracy of feeding and metering, so that the feeding device of the present invention can meet the requirements of the explosive quantity accuracy for projectile injection.

[0017] 3. By setting up an inner shell and an outer shell, the outer shell can protect the internal structure. The double shell structure improves the overall strength and sealing of the feeding device and reduces the risk of liquid explosive leakage.

[0018] 4. By integrating the inner shell, outer shell, valve assembly, and metering assembly into one unit, the feeding device of the present invention has the advantage of a compact structure. Due to the compact structure of the feeding device, it can not only save the space for installing the feeding device, but also simplify the operation process for operators during use.
