Description

Technical Field

[0001] This utility model relates to the field of chemical production, specifically a safety feeding device for hazardous chemical raw materials. Background Technology

[0002] Chemical production is a processing method that uses chemical reactions to transform natural resources into desired new substances. It involves three main stages: raw material preparation and pretreatment, chemical reaction, and product refining. In the raw material preparation stage, raw materials need to be inspected and pretreated to ensure they meet production requirements. Next, the raw materials undergo a chemical reaction under specific conditions to transform into the target product. Finally, the product undergoes refining processes such as separation and purification to bring it up to market specifications. Chemical production not only produces diverse products but also has stringent process and technical requirements, making it an important part of the national economy. Feeding equipment is required to handle the loading of chemical raw materials during chemical production.

[0003] For example, authorization announcement number CN207107693U discloses a feeding device for powdered chemical raw materials, including a housing and a feeding device. The housing has a receiving chamber at its bottom, a discharge pipe fixed at its lower end, a crushing plate at its upper end, and a crushing shaft at its upper end. A tension rod is fixed to the left side of the crushing shaft via a rotating shaft, and a sleeve is located on the left side of the tension rod.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of a safety feeding device for hazardous chemical raw materials, comprising a storage tank 1, a feeding pipe 101 fixedly installed on one side of the upper middle portion of the storage tank 1, a sealing cap 102 fixedly installed on the upper end of the feeding pipe 101 to seal the feeding pipe 101 and prevent the chemical raw materials from escaping upward from the feeding pipe 101, a discharge pipe 103 fixedly installed on the lower middle portion of the storage tank 1, a first connecting plate 105 fixedly connected to the lower end of the discharge pipe 103, a lifting pipe device 3 installed on one side of the storage tank 1, one side of the lifting pipe device 3 extending to the lower end of the discharge pipe 103, and a control device fixedly installed in the middle of the discharge pipe 103. A feed pipe 301 is fixedly installed on the lower end of one side of the valve 104 and the lifting pipe device 3. A second connecting plate 302 is fixedly connected to the upper end of the feed pipe 301. The first connecting plate 105 at the lower end of the discharge pipe 103 and the second connecting plate 302 at the upper end of the feed pipe 301 are fixedly connected by a first bolt 303. A first sealing ring is provided between the first connecting plate 105 and the second connecting plate 302 to fix and connect the discharge pipe 103 and the feed pipe 301. The first sealing ring seals the gap between the first connecting plate 105 and the second connecting plate 302 to prevent chemical raw materials from escaping from the gap between the first connecting plate 105 and the second connecting plate 302.

[0024] Please see Figure 2-3 A stirring shaft 2 is rotatably connected to the center of the storage tank 1. Multiple stirring rods 201 are fixedly connected to the stirring shaft 2. A first driving device 202 is fixedly installed in the center of the upper end face of the storage tank 1. The upper end of the stirring shaft 2 extends out of the upper end face of the storage tank 1 and is fixedly connected to the output end of the first driving device 202. The first driving device 202 drives the stirring shaft 2 to rotate, which in turn drives the stirring rods 201 to rotate and stir the chemical raw materials inside the storage tank 1. When the storage tank 1 is discharged through the discharge pipe 103, the fluidity of the chemical raw materials is improved, thereby improving the discharge efficiency.

[0025] Please see Figure 1-2The chemical raw materials falling from the discharge pipe 103 enter the interior of the lifting pipe device 3 through the feed pipe 301. A lifting shaft 5 is rotatably connected to the middle of the lifting pipe device 3. A spiral blade 501 is fixedly mounted on the lifting shaft 5. A second drive device 502 is fixedly mounted at the upper end of the lifting pipe device 3. The upper end of the lifting shaft 5 extends beyond the upper end of the lifting pipe device 3 and is fixedly connected to the output end of the second drive device 502. The second drive device 502 drives the lifting shaft 5 to rotate, causing the lifting shaft 5 to drive the spiral blade 501 to rotate, thereby driving the chemical raw materials... The material is lifted inside the lifting pipe device 3. A rigid feeding pipe 304 is fixedly connected to the upper end of the other side of the lifting pipe device 3. A soft feeding pipe 4 is fixedly connected to the lower end of the rigid feeding pipe 304. A third connecting plate 401 is fixedly connected to the lower end of the soft feeding pipe 4. A second sealing ring 402 is fixedly installed on the lower end face of the third connecting plate 401. The third connecting plate 401 at the lower end of the soft feeding pipe 4 is fixed to the feed inlet of the chemical production device by the second bolt, and the gap is sealed by the second sealing ring 402 to prevent the chemical raw materials from escaping.

[0026] Working Principle: In operation, chemical raw materials are first added to the storage tank 1 through the feeding pipe 101, and the sealing cap 102 ensures the sealing of the feeding process. Then, the control valve 104 is opened, and the chemical raw materials fall along the discharge pipe 103 under gravity, entering the feed pipe 301 of the lifting pipe device 3 through the connection between the first connecting plate 105 and the second connecting plate 302, sealed by the first sealing ring. At this time, the first drive device 202 drives the stirring shaft 2 and the stirring rod 201 to rotate, enhancing the flowability of the chemical raw materials and ensuring smooth feeding. Next, the second drive device 502 is activated, driving the lifting shaft 5 and its spiral blades 501 to rotate, lifting the chemical raw materials from the bottom to the top of the lifting pipe device 3, and conveying them to the feed inlet of the chemical production unit through the rigid feed pipe 304 and the flexible feed pipe 4. When connecting the soft feed pipe 4 to the chemical production device, the third connecting plate 401 and the second sealing ring 402 below it are used to ensure the sealing of the connection, effectively preventing the chemical raw materials from escaping during the transportation process, thereby ensuring production safety.
