Description

Technical Field

[0001] This utility model relates to the field of feeding devices, specifically a chemical safety feeding device. Background Technology

[0002] Chemical safety feeding devices are used in chemical production to safely and accurately add raw materials to reactors or production equipment. They aim to reduce operational risks, prevent accidents, and ensure the stability and safety of the production process. Because the raw materials involved in chemical production may have flammable, explosive, toxic, or corrosive properties, the design and use of safety feeding devices are particularly important.

[0003] However, current chemical safety feeding devices still have some shortcomings. For example, the automatic sealing of the feed inlet of existing chemical safety feeding devices is poor, which means that when the raw materials are put into the device, the staff need to spend extra time sealing the feed inlet. This interferes with the staff's feeding efficiency and has certain defects in use.

[0004] Therefore, there is an urgent need to improve this shortcoming. This utility model is to study and improve the existing structure to provide a chemical safety feeding device. Utility Model Content

[0005] The purpose of this invention is to provide a chemical safety feeding device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chemical safety feeding device, comprising a storage tank and a feeding hopper, wherein a drive motor is installed on the top of the storage tank, and a mixing component is installed on the output shaft of the drive motor via a coupling; the feeding hopper is fixedly installed on the top of the storage tank, and a sealing mechanism is symmetrically and rotatably connected inside the feeding hopper; a sealing frame is fixedly installed on the inner surface of the feeding hopper, and a cover plate is attached to the top of the sealing frame, while a positioning plate is fixedly installed at the bottom of the cover plate.

[0007] Furthermore, the mixing assembly includes a drive shaft, a fixed sleeve, a stirring rod, and a scraping mechanism. The fixed sleeve is installed at equal intervals on the outer surface of the drive shaft, and the stirring rod is installed at equal intervals in a ring on the outer surface of the fixed sleeve. The scraping mechanism is fixedly installed on the outer surface of the drive shaft.

[0008] Furthermore, the inner surface of the fixed sleeve is fixedly connected to the outer surface of the drive shaft, and the outer surface of the fixed sleeve is fixedly connected to the end of the stirring rod, and the stirring rod and the drive shaft form a fixed structure through the fixed sleeve.

[0009] Furthermore, the scraping mechanism includes a connecting sleeve, a connecting rod, and an arc-shaped scraper. The connecting sleeve has connecting rods installed at equal intervals in a ring on its outer surface, and the ends of the connecting rods are fixedly connected to the arc-shaped scraper.

[0010] Furthermore, the end of the connecting rod is fixedly connected to the outer surface of the connecting sleeve, and the other end of the connecting rod is fixedly connected to the inner surface of the arc-shaped scraper, and the arc-shaped scraper forms a fixed structure with the connecting sleeve through the connecting rod.

[0011] Furthermore, the sealing mechanism includes a sealing plate, a rubber sealing gasket, and a connecting shaft. The rubber sealing gasket is fixedly installed on the inner surface of the sealing plate, and the connecting shaft is fixedly connected through the inside of the sealing plate. Moreover, the end of the connecting shaft is elastically connected to the inside of the feeding hopper through a torsion spring.

[0012] Furthermore, the outer surface of the connecting shaft is fixedly connected to the inner surface of the sealing plate, and the end of the connecting shaft is rotatably connected to the inside of the feeding hopper, and the sealing plate forms a rotating structure with the feeding hopper through the connecting shaft.

[0013] Furthermore, the external dimensions of the positioning plate perfectly match the internal dimensions of the sealing frame, and the positioning plate and the sealing frame form a locking structure.

[0014] This utility model provides a chemical safety feeding device, which has the following beneficial effects:

[0015] 1. This utility model, through the setting of a connecting shaft and a sealing frame, allows the top of the sealing plate to automatically rotate downwards when subjected to force, thereby achieving automatic opening for easy material loading by the operator. Then, by setting a torsion spring on the outer surface of the end of the connecting shaft, the sealing plate can reclose through the rotation of the connecting shaft when the force point on the top of the sealing plate disappears, thus providing convenience for the operator to load materials. This avoids the situation where the operator needs to spend time sealing the inlet of the device after putting the raw materials into the device, which would interfere with the operator's loading efficiency. Furthermore, through the cooperation of the rubber sealing gasket and the sealing frame, the sealing plate has better sealing performance when it closes automatically. At the same time, the setting of the cover plate and the positioning plate allows the operator to further seal the feeding hopper after all the materials have been added, thereby effectively improving the sealing performance of the feeding hopper.

[0016] 2. This utility model, through the setting of the drive shaft, enables the drive motor to drive the stirring rod and scraping mechanism to rotate synchronously inside the storage tank during operation. This allows the stirring rod to quickly stir the chemical raw materials to be added into the storage tank. Furthermore, through the cooperation of the connecting sleeve and the connecting rod, the arc-shaped scraper can scrape the inner surface of the storage tank while the stirring rod is stirring the raw materials, thereby ensuring that no raw materials stick to the inner surface of the storage tank, thus effectively improving the mixing effect of the feeding device.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figure 1 , Figure 3 and Figure 4As shown, a chemical safety feeding device includes a storage tank 1 and a feeding hopper 4. The feeding hopper 4 is fixedly installed on the top of the storage tank 1, and a sealing mechanism 5 is symmetrically rotatably connected inside the feeding hopper 4. The sealing mechanism 5 includes a sealing plate 51, a rubber sealing gasket 52, and a connecting shaft 53. The rubber sealing gasket 52 is fixedly installed on the inner surface of the sealing plate 51, and the connecting shaft 53 is fixedly connected through the interior of the sealing plate 51. The outer surface of the connecting shaft 53 is fixedly connected to the inner surface of the sealing plate 51, and the end of the connecting shaft 53 is rotatably connected to the interior of the feeding hopper 4. The sealing plate 51 and the feeding hopper 4 form a rotating structure through the connecting shaft 53. The sealing plate 51 and the feeding hopper 4 are configured as rotating structures, making the automatic opening and closing operation of the sealing plate 51 smoother. The end of the connecting shaft 53 is elastically connected to the inside of the feeding hopper 4 through a torsion spring. A sealing frame 6 is fixedly installed on the inner surface of the feeding hopper 4, and a cover plate 7 is attached to the top of the sealing frame 6. At the same time, a positioning plate 8 is fixedly installed at the bottom of the cover plate 7. The external dimensions of the positioning plate 8 are completely matched with the internal dimensions of the sealing frame 6, and the positioning plate 8 and the sealing frame 6 form a locking structure. By setting the positioning plate 8 and the sealing frame 6 as a locking structure, the positioning plate 8 can easily be locked into the inside of the sealing frame 6 to complete the sealing work.

[0024] like Figure 1 and Figure 2 As shown, a drive motor 2 is installed on the top of the storage tank 1, and a mixing assembly 3 is installed on the output shaft of the drive motor 2 via a coupling. The mixing assembly 3 includes a drive shaft 31, a fixed sleeve 32, a stirring rod 33, and a scraping mechanism 34. The fixed sleeve 32 is installed at equal intervals on the outer surface of the drive shaft 31, and the stirring rod 33 is installed at equal intervals in a ring on the outer surface of the fixed sleeve 32. The inner surface of the fixed sleeve 32 is fixedly connected to the outer surface of the drive shaft 31, and the outer surface of the fixed sleeve 32 is fixedly connected to the end of the stirring rod 33. The stirring rod 33 and the drive shaft 31 form a fixed structure through the fixed sleeve 32. By setting the stirring rod 33 and the drive shaft 31 into a fixed structure, the stirring rod 33 will not move when the drive shaft 31 drives the stirring rod 33 to stir the raw materials. The material scraping mechanism 34 is fixedly installed on the outer surface of the drive shaft 31. The material scraping mechanism 34 includes a connecting sleeve 341, a connecting rod 342, and an arc-shaped scraper 343. The connecting rod 342 is installed in a ring at equal intervals on the outer surface of the connecting sleeve 341. The arc-shaped scraper 343 is fixedly connected to the end of the connecting rod 342. The end of the connecting rod 342 is fixedly connected to the outer surface of the connecting sleeve 341, and the other end of the connecting rod 342 is fixedly connected to the inner surface of the arc-shaped scraper 343. The arc-shaped scraper 343 and the connecting sleeve 341 form a fixed structure through the connecting rod 342. By setting the arc-shaped scraper 343 and the connecting sleeve 341 into a fixed structure, the arc-shaped scraper 343 will not loosen when scraping material along the inner surface of the storage bucket 1.

[0025] In summary, this chemical safety feeding device firstly... Figures 1 to 4 As shown in the diagram, the worker grasps the handle at the top of the cover plate 7 and lifts it up. Then, the worker presses down on the sealing plate 51, causing it to open inwards via the rotation of the connecting shaft 53. Next, the worker injects raw materials into the hopper 4 via the injection pipe or by direct pouring, and the materials are then conveyed into the storage tank 1. Once one type of raw material has been injected, the worker releases their grip, causing the connecting shaft 53 to rotate back due to the spring's return force, thus closing the sealing plate 51 again. At this point, the cooperation of the rubber sealing gasket 52 and the sealing frame 6 prevents a large amount of dust or harmful gases from leaking out of the hopper 4. When other raw materials need to be added, the sealing mechanism 5 can be reopened by pressing the sealing plate 51, greatly improving the sealing performance of the hopper 4. After all the material is injected, the cover plate 7 is grasped and the positioning plate 8 is inserted into the sealing frame 6 to complete the secondary sealing work. Then, the operator turns on the drive motor 2 through the controller. When the drive motor 2 starts running, it drives the drive shaft 31 to rotate inside the storage tank 1. At this time, through the connection of the fixed sleeve 32 and the connecting sleeve 341, the fixed sleeve 32 and the connecting rod 342 rotate inside the storage tank 1 to achieve the purpose of mixing and stirring the chemical raw materials in the storage tank 1. At the same time, as the connecting rod 342 rotates, the arc scraper 343 rotates along the inner surface of the storage tank 1 to scrape the sticky raw materials, thereby improving the mixing effect of the device. After the raw materials are mixed, they are automatically stored inside the storage tank 1. When the operator needs to add material, the control valve of the discharge port at the bottom of the storage tank 1 can be opened.
