Description

Technical Field

[0001] This utility model relates to the field of antistatic technology, specifically to a silicon-magnesium alloy unloading device for preventing static electricity ignition. Background Technology

[0002] Silane (SiH4) is a key precursor material in the semiconductor, photovoltaic, and new display panel manufacturing industries, and its efficient and safe preparation technology has significant industrial value. Currently, the mainstream industrial methods for silane preparation include the magnesium silicide method (Komatsu method), the lithium aluminum hydride reduction method, and the fluorosilicate method. Among these, the magnesium silicide method has become the widely adopted technology both domestically and internationally due to its readily available raw materials and mature process route. The existing magnesium silicide process route involves the reaction of a silicon-magnesium alloy with ammonium chloride in a liquid ammonia environment to obtain silane: Mg2Si + 4NH4Cl → 2MgCl2·6NH3 + SiH4↑.

[0003] The silicon-magnesium alloy is used as a reaction raw material and is also an intermediate product of our company. It is prepared by reacting magnesium powder and silicon powder through a high-temperature solid-state reaction, and then cooled to room temperature before being unloaded from the furnace. Currently, the silicon-magnesium alloy furnace body is typically hoisted to the unloading point. Workers use tools to tilt the furnace body until it is level at the unloading point, and then manually transfer the material inside the furnace body into a receiving container using unloading tools. During this manual material transfer process, static electricity is generated due to friction between the material and the inner wall of the furnace, which can easily cause fires or explosions, resulting in serious casualties and property damage.

[0004] In existing technologies, static electricity on the furnace body is often conducted to the ground using electrostatic clamps to avoid the accumulation of static electricity and potential hazards. However, manual grounding is required every time the furnace body discharges material, which increases the number of operating steps. If the staff misses this operation, a safety accident may easily occur due to static electricity. Utility Model Content

[0005] The purpose of this invention is to provide a silicon-magnesium alloy tapping device that prevents static electricity and fire, so as to solve the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A silicon-magnesium alloy unloading device for preventing static electricity ignition includes a cylindrical furnace body and a mounting frame. The mounting frame is equipped with a guiding mechanism, which includes: a first receiving part rotatably mounted on the mounting frame for receiving the bottom of the furnace body; a second receiving part fixedly mounted on the mounting frame for receiving the side wall of the furnace body; and a conductive part disposed on the second receiving part to transfer static electricity on the furnace body to the ground.

[0008] Furthermore, the first receiving part includes a chassis rotatably connected to the mounting frame, an arc-shaped plate fixedly connected to the chassis, the arc-shaped plate being adapted to the side wall of the furnace body, a reset assembly for resetting the chassis and the arc-shaped plate being provided on the mounting frame, and a first limiting part and a second limiting part for limiting the position of the chassis and the arc-shaped plate being fixedly provided on the mounting frame respectively.

[0009] Furthermore, the reset assembly includes a connecting rod, the two ends of which are rotatably connected to the arc-shaped plate and the sliding part, respectively. The sliding part is slidably connected to the mounting bracket, and a reset spring is provided between the mounting bracket and the sliding part.

[0010] Furthermore, the sliding part includes a first sliding rod rotatably connected to the connecting rod, a fixed rod is fixedly connected to the end of the first sliding rod, and a plurality of second sliding rods are fixedly connected to the fixed rod. Each second sliding rod is arranged parallel to the first sliding rod and slidably connected to the mounting bracket. The return spring is installed between the second sliding rod and the mounting bracket.

[0011] Furthermore, the second receiving part includes a support rod fixedly mounted on the mounting frame, and an arc-shaped support plate is fixedly connected to the end of the support rod, the support plate being adapted to the side wall of the furnace body.

[0012] Furthermore, when the furnace body abuts against the arc-shaped plate and the support plate respectively, the furnace body is horizontal.

[0013] Furthermore, the conductive part includes an arc-shaped first conductive block fixedly disposed in a slot on the support plate. The first conductive block is fixedly connected to a second conductive block. The second conductive block is fixedly disposed inside the support plate, and its end extends out from the support rod and connects to the conductive plate.

[0014] The beneficial effects of the anti-static ignition silicon-magnesium alloy tapping device provided by this utility model in the above technical solution are as follows:

[0015] 1. The furnace body is hoisted and moved to the mounting frame via the set guide mechanism, so that the bottom of the furnace body is placed on the first receiving part. Then, the workers use rope tools to hoist the furnace body flat, so that the side wall of the furnace body abuts against the second receiving part. At this time, the side wall of the furnace body abuts against the grounded conductive part, so that the static electricity generated on the furnace body during the unloading process is conducted to the ground through the conductive part, reducing the safety risks caused by static electricity.

[0016] 2. With the first and second receiving parts set up, the furnace body will not shake when workers use the unloading tools to discharge materials after it is placed, which further ensures the safety of the unloading process.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0027] Please see Figure 1-4 A silicon-magnesium alloy unloading device for preventing static electricity ignition includes a cylindrical furnace body 1 and a mounting frame 2. The mounting frame 2 is equipped with a guiding mechanism 3, which includes: a first receiving part 31, rotatably mounted on the mounting frame 2, for receiving the bottom of the furnace body 1; a second receiving part 32, fixedly mounted on the mounting frame 2, for receiving the side wall of the furnace body 1; and a conductive part 33, mounted on the second receiving part 32, for transferring static electricity on the furnace body 1 to the ground through the conductive part 33.

[0028] The mounting bracket 2 is fixedly installed on the ground to prevent it from sliding during the descent of the furnace body 1. The conductive part 33 is grounded to conduct static electricity from the furnace body 1 to the ground during the unloading process, thus preventing accidents caused by static electricity. The mounting bracket, the first receiving part, and the second receiving part are made of or wrapped with non-conductive materials (such as polytetrafluoroethylene, silicone, etc.) to avoid the risk of electric shock to workers if they accidentally touch the parts when the factory voltage is abnormal.

[0029] Furthermore, the first receiving part 31 includes a chassis 311 rotatably connected to the mounting frame 2, an arc-shaped plate 312 fixedly connected to the chassis 311, the arc-shaped plate 312 being adapted to the side wall of the furnace body 1, the mounting frame 2 is also provided with a reset assembly for resetting the chassis 311 and the arc-shaped plate 312, and the mounting frame 2 is also respectively fixedly provided with a first limiting part 313 and a second limiting part 314 for limiting the position of the chassis 311 and the arc-shaped plate 312.

[0030] Referring to the accompanying drawings, the first limiting part 313 and the second limiting part 314 are respectively used to limit the position of the chassis 311 in the horizontal and vertical states, so as to facilitate the placement of the furnace body 1 on the chassis 311 during hoisting and to maintain the horizontal state of the furnace body 1 during material discharge.

[0031] Furthermore, the reset assembly includes a connecting rod 315, the two ends of which are rotatably connected to the arc plate 312 and the sliding part 317, respectively. The sliding part 317 is slidably connected to the mounting frame 2, and a reset spring 316 is provided between the mounting frame 2 and the sliding part 317.

[0032] The reset component enables the chassis 311 to automatically reset from a vertical position to a horizontal position after the furnace body 1 is moved. On the other hand, it reduces the rotational speed of the chassis 311 and the arc plate 312 (the reset spring 316 is compressed to provide resistance), so as to avoid the furnace body 1 from falling rapidly and colliding with the second receiving part 32, which would affect its service life.

[0033] Furthermore, the sliding part 317 includes a first sliding rod 3171 rotatably connected to the connecting rod 315. A fixed rod 3173 is fixedly connected to the end of the first sliding rod 3171. A plurality of second sliding rods 3172 are fixedly connected to the fixed rod 3173. Each second sliding rod 3172 is arranged parallel to the first sliding rod 3171 and is slidably connected to the mounting bracket 2. The return spring 316 is installed between the second sliding rod 3172 and the mounting bracket 2.

[0034] During the process of the furnace body 1 rotating from a vertical position to a horizontal position, the arc plate 312 is driven to rotate. The rotation of the arc plate 312 drives the first sliding rod 3171 to slide along the mounting frame 2 through the connecting rod 315. The first sliding rod 3171 drives multiple second sliding rods 3172 to slide along the mounting frame 2 through the fixed rod 3173, and compresses the corresponding return spring 316.

[0035] Understandably, the end of the second sliding rod 3172 is fixedly connected to an anti-detachment rod 3174, and a return spring 316 passes through the outside of the anti-detachment rod 3174 to prevent it from detaching from the second sliding rod 3172 and the mounting bracket 2. The anti-detachment rod 3174 is slidably connected to the mounting bracket 2.

[0036] Furthermore, the second receiving part 32 includes a support rod 321 fixedly mounted on the mounting frame 2, and an arc-shaped support plate 322 is fixedly connected to the end of the support rod 321. The support plate 322 is adapted to the side wall of the furnace body 1.

[0037] Furthermore, when the furnace body 1 abuts against the arc-shaped plate 312 and the support plate 322 respectively, the furnace body 1 is horizontal. That is, the arc-shaped plate 312 and the support plate 322 are at the same height, preventing the furnace body 1 from tilting and sliding. It is worth noting that at this time, the second limiting part 314 abuts against the arc-shaped plate 312 to prevent the arc-shaped plate 312 from driving the chassis 311 to continue rotating, thus ensuring the stability of the furnace body 1.

[0038] Furthermore, the conductive part 33 includes an arc-shaped first conductive block 331 fixedly disposed within a slot on the support plate 322. The first conductive block 331 is fixedly connected to a second conductive block 332. The second conductive block 332 is fixedly disposed inside the support plate 322, and its end extends out from the support rod 321 and connects to the conductive plate 333. The first conductive block, the second conductive block, and the conductive plate are all made of conductive material.

[0039] A stud is fixedly installed on the conductive plate 333, and a wire is fixed to the conductive plate 333 by a nut. The other end of the wire is electrically connected to the grounding terminal. This grounding method is a common technique used by those skilled in the art and will not be described in detail.

[0040] Working principle: The furnace body 1 is hoisted and moved to the mounting frame 2, so that the bottom of the furnace body 1 rests on the chassis 311. The worker uses rope tools and hoisting tools to rotate the furnace body 1. The rotation of the furnace body 1 drives the arc plate 312 to rotate. The rotation of the arc plate 312 drives the sliding part 317 to move through the connecting rod 315 and compress the return spring 316 to reduce the rotation speed of the furnace body 1 until the side wall of the furnace body 1 abuts against the support plate 322. At this time, the side wall of the furnace body 1 abuts against the first conductive block 331, so that during the furnace unloading process, the static electricity on the furnace body 1 passes through the first conductive block 331, the second conductive block 332, and the conductive plate 333 in sequence, and is conducted to the grounding terminal through the wire.

[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
