[0023] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.

[0024] A chemical safety feeding device includes a feeding fixing frame assembly 1, a lifting and feeding assembly 2, a raw material suspension frame 3, a feeding assembly 5, and a raw material package plate 6; wherein: the lifting and feeding assembly 2 is fixedly installed on the top of the feeding fixing frame assembly 1, the lifting and feeding assembly 2 lifts the raw material suspension frame 3 for suspending the raw material package 4, and the raw material suspension frame 3 suspends the raw material package 4 containing chemical raw materials; the feeding assembly 5 is fixedly installed on the bottom of the feeding fixing frame assembly 1, and the raw material package plate 6 is welded and fixed to the middle of the feeding fixing frame assembly 1.

[0025] The feeding fixing frame assembly 1 includes four vertically arranged load-bearing rods 101, the bottom of which can be fixed to the cement ground by expansion bolts; four horizontally arranged first-layer fixing rods 102 are welded to the bottom of the four load-bearing rods 101, and two horizontally spaced hopper fixing rods 1021 are welded between two opposing first-layer fixing rods 102, with the feeding assembly 5 fixed between the two hopper fixing rods 1021; four horizontally arranged second-layer fixing rods are welded to the middle of the four load-bearing rods 101. The fixed rod 103 includes two horizontally spaced raw material packaging plate fixing rods 1031 welded between two opposing second-layer fixing rods 103, with a raw material packaging plate 6 fixed between the two raw material packaging plate fixing rods 1031; four horizontally arranged third-layer fixing rods 104 are welded and fixed to the top of the four load-bearing rods 101, and diagonal reinforcing rods 105 are welded between the two ends of each third-layer fixing rod 104 and the top of the load-bearing rod 101; two horizontally arranged long reinforcing rods 106 are welded and fixed to the middle of the four load-bearing rods 101.

[0026] The feeding fixing frame assembly 1 is made entirely of stainless steel, which has high strength and corrosion resistance. It can be used stably for a long time in the complex and harsh environment of chemical production, and is not prone to rust or damage, effectively extending the service life of the device and reducing maintenance costs. Its reasonable structural design, through the welding combination of fixing rods and reinforcing rods of each layer, ensures the stability and robustness of the entire fixing frame assembly, and can withstand various forces during the lifting of raw material package 4 and the feeding process, ensuring the safety and reliability of the feeding process.

[0027] The lifting and feeding assembly 2 includes a slide rail 201 welded to the bottom of the third-layer fixing rod 104 of the feeding fixing frame assembly 1. The slide rail 201 is made of I-beam steel, which has high load-bearing capacity and good bending resistance, ensuring that the CD1 type electric hoist 202 runs smoothly on the slide rail without shaking or jamming. The CD1 type electric hoist 202 is installed on the slide rail 201, and the raw material suspension frame 3 is installed at the bottom of the wire rope of the CD1 type electric hoist 202. The CD1 type electric hoist 202 has the advantages of simple operation, fast lifting speed, and accurate positioning, and can accurately lift the raw material suspension frame 3 to the specified height to meet the needs of different feeding heights. Moreover, the electric hoist is equipped with an overload protection device. When the weight of the lifted raw material bag exceeds the rated value, it will automatically stop running to avoid damage to the equipment or safety accidents due to overload.

[0028] The raw material suspension frame 3 includes a suspension frame body 301. A vertically placed U-shaped fixed pulley frame 303 is welded to the top of the suspension frame body 301. A fixed pulley 304 is installed in the middle of the fixed pulley frame 303 through a bearing. The steel wire rope of the lifting and feeding assembly 2 is installed on the fixed pulley 304. A cross-shaped suspension frame 302 is welded and fixed to the bottom of the suspension frame body 301. Raw material package strap limiting blocks 305 are provided at the four ends of the suspension frame 302. The four raw material package straps of the raw material package are respectively suspended on the four raw material package strap limiting blocks 305.

[0029] The suspension frame body 301 of the raw material suspension frame 3 is made of high-strength steel and can withstand the weight of the raw material package 4. The design of the fixed pulley frame 303 and fixed pulley 304 makes the movement of the wire rope smoother, reduces friction, reduces energy loss, and also improves the stability of lifting the raw material package 4. The cross-shaped suspension frame 302 and the raw material package belt limit block 305 ensure that the raw material package 4 will not shake or slip during the suspension process, ensuring the safety of the feeding process.

[0030] The raw material packaging plate 6 consists of two V-shaped steel plates. The raw material packaging plate 6 is welded and fixed between the raw material packaging plate fixing rod 1031, and a short reinforcing rod is welded and fixed between the raw material packaging plate 6 and the second layer fixing rod 103.

[0031] The two V-shaped steel plates of the raw material package plate 6 are designed to better support the raw material package 4 and prevent it from slipping during placement. The welding and fixing of the short reinforcing rods further enhances the connection strength between the raw material package plate 6 and the second-layer fixing rod 103, ensuring the stability of the entire device structure. During feeding, the raw material package plate 6 acts as a buffer and support, reducing the impact of the raw material package 4 on the device and extending its service life. In use, the binding rope at the bottom of the raw material package 4 is untied, the raw material package 4 is placed on the raw material package plate 6, and the discharge port is aligned with or placed into the feeding hopper 501 of the feeding assembly 5.

[0032] The feeding assembly 5 includes a feeding hopper 501 and a vertical pump 502. The feeding hopper 501 is welded and fixed between two first-layer fixing rods 102. A conveying pipe is installed at the bottom of the feeding hopper 501, and a valve and the vertical pump 502 are installed on the conveying pipe. The conveying pipe of the vertical pump 502 is connected to a designated production equipment.

[0033] The feeding hopper 501 of the feeding assembly 5 is welded from high-quality steel plate, with a smooth interior that prevents material residue and facilitates cleaning and maintenance. The capacity of the feeding assembly 5 is greater than that of a complete raw material package 4. The vertical pump 502, also known as a submersible slurry pump, is a centrifugal pump used to transport abrasive solid particles and high-concentration slurry. It can quickly and accurately transport chemical raw materials from the feeding hopper 501 to designated production equipment, improving feeding efficiency.
