Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of safe storage of magnesium powder, and particularly relates to a safe storage device for magnesium powder waste. BACKGROUND

[0002] In the production process of granular magnesium beans, the magnesium beans need to be ground because the magnesium beans need to be shaped and rounded. A large amount of magnesium powder waste is generated in the grinding process. Since magnesium powder is a lively metal and has flammable characteristics, special attention needs to be paid to safety during storage.

[0003] However, the existing storage method of magnesium powder waste is basically to pack the magnesium powder, and then to pack the ton bag in the designated area of the factory building, away from other materials. In this way, the ton bag can not burn other materials and equipment to a certain extent in the process of fire. However, since the conditions for ignition of magnesium powder are easy to achieve, for example, the air humidity is too large, it may cause the magnesium powder to ignite. After the ton bag burns, the magnesium powder will scatter under the action of air flow, which will also ignite other materials and increase economic losses. SUMMARY

[0004] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art and provide a safe storage device for magnesium powder waste. The magnesium powder is stored in a designated closed space, and the magnesium powder will not scatter after accidental fire, thereby not igniting other materials. At the same time, a temperature sensing fire extinguishing device is arranged above the closed space, which can automatically extinguish the fire when the magnesium powder burns, thereby reducing economic losses.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of this application.

[0032] Furthermore, the specification and claims of this invention use terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," to describe various exemplary structural parts and elements of the invention. However, these terms are used herein merely for illustrative purposes and are determined based on the exemplary orientations shown in the accompanying drawings. Therefore, these terms indicating direction are for illustrative purposes only and should not be considered as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0033] The following description, in conjunction with the accompanying drawings, provides a more detailed description of a safe storage device for magnesium powder waste according to the present invention.

[0034] Depend on Figures 1 to 8 As shown, a safe storage device for magnesium powder waste includes a box 1 with an open top, a top cover 2 on the top of the box 1, and a mounting hole 201 on the top cover 2, with a fire extinguishing device installed inside the mounting hole 201.

[0035] The upper cover plate 2 is provided with a feeding trough 3, which is open on both the upper and lower sides. The feeding trough 3 is connected to the inside of the box body 1. A cover 4 is detachably provided at the upper opening of the feeding trough 3.

[0036] The box 1 is equipped with a discharge device 5 inside, and the outlet of the discharge device 5 extends to the top of the upper cover plate 2.

[0037] Open the cover 4, and the magnesium powder waste is poured into the box 1 through the opening above the feed trough 3. It is stored inside the box 1. The fire extinguishing device adopts a temperature-sensing activation method. When the temperature inside the box 1 reaches the threshold, it proves that there is magnesium powder burning inside the box 1, and the fire extinguishing device will automatically activate to extinguish the fire.

[0038] In this embodiment, the discharge device 5 includes a vertical pipe 501, with a horizontal pipe 502 connected to the bottom of the vertical pipe 501. The horizontal pipe 502 has several suction holes 503, and the upper end of the vertical pipe 501 extends to the outside of the upper cover plate 2. A shut-off valve is provided on the vertical pipe 501, and the upper end of the vertical pipe 501 is connected to a negative pressure pipeline. The magnesium powder inside the box 1 is extracted by negative pressure suction.

[0039] Meanwhile, to facilitate the removal of magnesium powder, the bottom surface of the housing 1 is inclined, and the horizontal pipe 502 is positioned at the lowest point of the bottom surface of the housing 1. The entire discharge device 5 is supported by non-metallic materials, such as plastic pipes, to prevent sparks from being generated due to friction when removing magnesium powder.

[0040] Depend on Figures 5 to 7 As shown, the fire extinguishing device includes a sandbox 8, which has a rectangular horizontal cross-section and the bottom of the sandbox 8 protrudes below the bottom surface of the upper cover plate 2.

[0041] The sandbox 8 has an open bottom and is equipped with several base plates 9, which close the bottom of the sandbox 8. The base plates 9 are arranged in pairs facing each other, with the end of the base plate 9 away from the center of the sandbox 8 rotatably connected to the side wall of the sandbox 8. The two opposing base plates 9 are fixedly connected by a fusible link 10.

[0042] The sandbox 8 is filled with sand for fire extinguishing. The sandbox 8 is open at the top to facilitate observation of the sand level.

[0043] A guardrail is installed around the sandbox 8 to prevent personnel from accidentally entering it. To improve the support strength of the base plate 9, the two oppositely arranged base plates 9 are fixedly connected by at least two fusible links 10. Each end of the fusible link 10 has a through hole, and a bolt passes through the through hole. The two bolts are threaded into the threaded holes on the two base plates 9 respectively to complete the fixation of the two base plates 9.

[0044] The fixed base plate 9 is arranged horizontally, sealing the bottom of the sandbox 8. The fusible link 10 is the temperature control component of the fire extinguishing device. In order to improve the temperature sensitivity, a heat-conducting wire 11 is attached to the bottom of the fusible link 10, and the heat-conducting wire 11 extends to the bottom of the box 1.

[0045] When the magnesium powder inside the box 1 catches fire, the heat-conducting wire 11 at the corresponding position transfers the high temperature to the fusible link 10. The fusible link 10 melts under the action of high temperature, and the two base plates 9 disconnect. Under the action of gravity of the sand placed on top, it rotates downward to open, and the sand falls to cover the magnesium powder at the fire.

[0046] Of course, the bottom of the sandbox 8 can also be provided with only two oppositely arranged bottom plates 9, so that after the magnesium powder inside the box 1 burns, the sand inside the sandbox 8 can be completely spilled out for fire extinguishing.

[0047] To prevent excessive humidity in the remaining space inside the housing 1, a protective gas system is installed on the outside of the housing 1. The inlet pipe 6 and outlet pipe 7 of the protective gas system pass through the upper cover plate 2 and are connected to the interior of the housing 1. Figure 8 As shown, the protective gas system includes an inlet pipe 6, a gas storage tank 14, a shut-off valve 15, an induced draft fan 12, a dryer 13, and an exhaust pipe 7, which are connected in sequence. The inlet pipe 6 and the exhaust pipe 7 are respectively connected to two inclined diagonal areas of the housing 1.

[0048] The gas flowing into the chamber 1 is dried by the dryer 13, which reduces the humidity of the gas inside the chamber 1 and further reduces the risk of magnesium powder ignition.

[0049] Meanwhile, inert gases such as carbon dioxide can be added inside the gas storage tank 14 to reduce the oxygen content and further reduce the risk of magnesium powder ignition.

[0050] The box 1 can be buried in a pit dug in the ground, or it can be dug directly in the ground and built into a pit with cement bricks and stones, and used as a box.

[0051] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
