Description

Technical Field

[0001] This utility model relates to the technical field of trichlorosilane production equipment, and in particular to a device for reversing residual liquid from trichlorosilane cylinders. Background Technology

[0002] Trichlorosilane, also known as silicochloroform or trichlorosilane, is a colorless liquid with a pungent odor and is classified as a Class 1 flammable and explosive substance in contact with water. This compound has a melting point of -127°C, a boiling point of 32-34°C, a vapor pressure of 9.75 psi (20°C), and a flash point of only 7°F. It decomposes violently upon contact with water. Chemically reactive, it is flammable and burns intensely upon contact with an open flame, producing silicon dioxide, hydrogen chloride, and chlorine gas, accompanied by a red flame and white smoke.

[0003] Therefore, trichlorosilane is stored in steel cylinders for convenient transportation and storage. To ensure the safety of trichlorosilane storage and use, the steel cylinders used are relatively expensive, so used cylinders are recycled for reuse.

[0004] The recycled trichlorosilane cylinders often contain residual liquid. To ensure the safe and stable use of the cylinders, the residual liquid is recovered. After inspection and verification, cylinders that meet the allowable conditions can be refilled and put back into the market.

[0005] In existing technologies, when recovering residual liquid, the cylinders are manually turned over and placed on a support frame to recover the residual liquid inside. However, this manual operation is labor-intensive, inefficient, and carries the risk of the cylinders tipping over and falling during the turning process.

[0006] Therefore, there is an urgent need for a residual liquid inverting device for trichlorosilane steel cylinders to solve the above-mentioned technical problems. Utility Model Content

[0007] The purpose of this invention is to overcome existing technical problems and provide a device for pouring out residual liquid from trichlorosilane steel cylinders.

[0008] To achieve the above objectives, this utility model is implemented according to the following technical solution: The residual liquid inverting device for trichlorosilane steel cylinders includes a fixed frame, a flipping mounting frame, and a drive assembly; the flipping mounting frame is rotatably connected to the fixed frame via a connecting shaft, and the drive assembly drives the flipping mounting frame to flip around the connecting shaft; the fixed frame includes a support base and support columns fixedly installed on the left and right sides of the upper end face of the base; The flip-mount frame includes a vertically arranged rectangular frame, and limiting components A, B, C, and a support plate arranged on the front end face of the rectangular frame; the limiting components A, B, C, and support plate are arranged sequentially from top to bottom. The rear end face of the rectangular frame is fixedly connected to the connecting shaft, and the connecting shaft is rotatably connected to the support columns on the left and right sides; The trichlorosilane cylinder is detachably mounted on a flip-up mounting bracket.

[0009] The drive components in this invention can be any commonly used ones in the prior art, such as a drive motor to drive the connecting shaft to rotate, or a meshing gear and rack to drive the connecting shaft to rotate, etc.

[0010] Specifically, there are two sets of drive components, located on the left and right sides of the rotating shaft respectively. The drive components include a gear, a rack, and two synchronous cylinders. The gear is fixedly connected to the end of the rotating shaft, and a rack is meshed on the front side of the gear. The rack is slidably mounted on the support column via connecting block A. Connecting block B is fixedly mounted on the outer side of connecting block A, and the lower end face of connecting block B is fixedly connected to the moving ends of the two synchronous cylinders. The two synchronous cylinders move synchronously, driving connecting block B to move up and down. Connecting block B drives the rack on connecting block A to move up and down, and the rack drives the gear meshing with it to rotate clockwise or counterclockwise, thereby driving the entire rotating shaft to rotate.

[0011] The two drive components consist of four synchronized cylinders, which extend and retract synchronously to drive the rotating shaft. The selection and control of the synchronized cylinders are existing technologies, and those skilled in the art can select the required model and control method according to actual usage requirements.

[0012] Preferably, the rectangular frame consists of horizontal bars A, B, C, and D from top to bottom, and vertical bars A, B, and C from left to right; multiple threaded holes A are provided at equal intervals on the vertical bars A, B, and C between horizontal bars A and B.

The upper plate is provided with two U-shaped grooves with openings facing forward. The rear plate is detachably fixed to a rectangular frame above the crossbar B by screws A.

[0014] The size of the U-shaped groove of the limiting component A is mainly matched to the neck of the trichlorosilane cylinder. The neck of the trichlorosilane cylinder can be locked in the U-shaped groove to prevent it from moving up and down during the flipping process. The screw A and the threaded hole A are threaded together, so the position of the limiting component A can be adjusted to suit trichlorosilane cylinders of different heights.

[0015] Preferably, the limiting component B includes a mounting frame and a limiting plate; the mounting frame includes three connecting rods and one limiting rod; the connecting rods are fixedly connected to vertical rod A, vertical rod B and vertical rod C from left to right; the front ends of the three connecting rods are detachably connected to the limiting rod.

[0016] Preferably, two elastic washers are provided on the rear side of the limiting rod; the two elastic washers are located on the left and right sides of the middle connecting rod respectively; and the left and right ends of the elastic washers are in contact with the corresponding connecting rods respectively.

[0017] The position of the V-groove of the limiting component B corresponds to the position of the U-groove of the limiting groove A. The V-groove combined with the limiting rod is mainly to clamp the body of the trichlorosilane steel cylinder and prevent it from moving back and forth during the flipping process.

[0018] Preferably, the limiting member C has the same structure as the limiting member B.

[0019] Preferably, the limiting component C includes a mounting frame and a supporting folding plate; the supporting folding plate is an integral structure, including a horizontal plate and a vertical edge at the front end of the horizontal plate.

[0020] The components installed on the limiting member C can be customized according to actual usage requirements. When support is needed, a support plate can be installed; when limiting is required, a limiting plate can be installed. This design is applicable to trichlorosilane cylinders of different heights. Furthermore, both the limiting member A and the limiting plate of this invention are detachable, allowing for the manufacture of limiting members A with U-shaped grooves of different sizes and limiting plates with V-shaped grooves of different sizes to accommodate trichlorosilane cylinders of different diameters. This makes the invention more flexible in use.

[0021] Preferably, the supporting folding plate further includes two limiting folding plates disposed at the rear end of the horizontal plate, the two limiting folding plates being respectively located on the left and right sides of the vertical rod B; the limiting folding plate includes a vertical baffle and a horizontal clamping plate; the horizontal clamping plate is provided with a V-shaped groove that matches the limiting clamping plate.

[0022] The horizontal clamp is designed to restrict the position of the trichlorosilane cylinder, and the vertical edge also acts as a limit during use to prevent the bottom of the trichlorosilane cylinder from tilting up during the flipping process.

[0023] Preferably, a positioning component is also provided on the support base on the rear side of the flip mounting bracket; the positioning component includes two mounting plates and a positioning rod; the mounting plates are symmetrically arranged on the left and right; the mounting plates are provided with two inclined grooves of different heights; the inclined groove on the rear side is higher than the inclined groove on the front side; both ends of the positioning rod are provided with external threads, and the two ends of the positioning rod are respectively placed in the corresponding inclined grooves and fixedly connected to the mounting plates by nuts.

[0024] The positioning components facilitate positioning and support of the flip-up mounting frame after it has been flipped, preventing over-flipping. Additionally, two tilting slots are provided, allowing for two different positioning angles for the flip-up mounting frame after it has been flipped, making it more flexible to use.

[0025] Components not specified in this invention are all made using conventional methods in the field. Those skilled in the art can select their models and installation methods according to actual usage needs, and clearly understand how to install and control them. They will not be described in detail here.

[0026] The beneficial effects of this utility model are: This invention features a simple structure, capable of installing and flipping four trichlorosilane cylinders simultaneously. The flipping efficiency is high, significantly reducing the difficulty of manual operation. Furthermore, it prevents the cylinders from falling during the flipping process, making it safer than manual flipping. The height of limiter A is adjustable, the limit plate of limiter B is replaceable, and the support plate of limiter C is replaceable, allowing this invention to be applied to various types of trichlorosilane cylinders, making it more flexible in use.
