Description

Technical Field

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

[0002] Chemical feeding is a crucial initial step in the chemical production process. It refers to the process of feeding various raw materials (such as solids, liquids, and gases) into reaction equipment (such as reaction vessels, reactors, and feeding tanks) according to process requirements. This step directly affects the efficiency of subsequent chemical reactions, product quality, and production safety. Therefore, it requires precise operation in combination with process characteristics, equipment functions, and safety regulations.

[0003] Current chemical feeding equipment often relies on manual operation for clamping and cutting chemical bags. This method is not only inefficient, but also poses a safety hazard to operators who may be cut by the cutting tools during the bag cutting process. In addition, traditional equipment cannot adapt to the size of the bag, and cannot ensure that the bag opening is fully opened, which can easily cause material blockage and reduce feeding efficiency. Furthermore, traditional clamping structures usually use a fixed clamping force, which may result in the bag slipping due to insufficient clamping force, or damage to the bag and the internal material due to excessive clamping force. It also aggravates wear between the equipment and the bag, increasing equipment maintenance costs and replacement frequency. Utility Model Content

[0004] The purpose of this invention is to provide a chemical safety feeding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chemical safety feeding device, comprising a feeding barrel and a feeding gate, wherein the feeding gate is rotatably located inside one side wall of the feeding barrel, a filter screen is fixed to the inner wall of the feeding barrel, a material support is fixed to the inner wall of the feeding barrel, a cutting blade is fixed to the center of the top end of the material support, a drive screw is threaded inside the material support, a limit rod is fixed to the top end of the material support, clamping components are fixed to both sides of the top end of the material support, and a drive component slides inside the clamping component.

[0006] Preferably, the top end of the limiting rod is tapered, which can cooperate with the clamping component to limit and fix the chemical bag.

[0007] Preferably, the material support includes a sliding support rod, the inner wall of the feeding barrel is fixed with the sliding support rod, the top end of the sliding support rod is slidably connected to a material support slide rod, the inner side wall of the material support slide rod is rotatably connected to a driving support rod, and one end of the outer wall of the driving support rod is rotatably connected to a driving slider.

[0008] Preferably, the drive slider has a through hole inside, and the through hole is provided with a thread that matches the outer wall of the drive screw, which can drive the drive slider to move.

[0009] Preferably, the clamping component includes a vertical support rod, a vertical support rod is fixed to one side of the top end of the support slide rod, a limiting horizontal plate is fixed to the top end of the vertical support rod, a sliding plate is slidably attached to the outer wall of the vertical support rod, and a clamping horizontal plate is fixed to the bottom end of the sliding plate.

[0010] Preferably, one end of a spring is fixed to the bottom of the sliding plate, and the other end of the spring is fixed to a clamping plate, so that the clamping force of the chemical bag is maintained by the elastic sliding clamping plate of the spring.

[0011] Preferably, the driving component includes a driving rack, the bottom end of the limiting horizontal plate is slidably provided with the driving rack, the bottom end of the driving rack is engaged with a driven gear, and the driven gear rotates at the bottom end of the limiting horizontal plate, and a driving eccentric wheel is fixed to one side wall of the driven gear.

[0012] Preferably, one end of the drive rack is fixed with a telescopic rod, thereby enabling the drive racks on both sides to move.

[0013] Preferably, a groove is formed at one end of the drive eccentric wheel, and a protrusion is formed at the top of the sliding plate, which cooperates with the groove at one end of the drive eccentric wheel to limit its movement.

[0014] Preferably, a return spring is provided inside the bottom end of the limiting horizontal plate and the top end of the sliding plate, and the elasticity of the return spring can drive the sliding plate to return to its original position.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The filter screen fixed to the inner wall of the feeding hopper can efficiently filter materials during the feeding process, accurately intercept impurities, effectively prevent impurities from entering the chemical production process, ensure the quality of chemical products from the source, reduce production failures and product quality problems caused by impurities, reduce production risks, and improve production stability.

[0017] Through the coordinated operation of the drive unit, clamping unit, and support unit, the chemical bag is clamped and cut. The drive rack drives the driven gear and drive eccentric wheel to rotate, pushing the sliding plate and clamping cross plate to move down and clamp the bag. With the conical limit design of the limit rod, the bag is ensured to be fixed and stable. Then, the drive screw drives the slider and the cutting blade to move to complete the cutting. The whole process does not require direct manual contact with the cutting operation, which greatly reduces the risk of operators being cut and significantly improves the safety of feeding operation.

[0018] When the drive slider moves, it drives the drive rod to push the support slide bar outward on the support slide bar, causing the limit plug to open the chemical bag outward. This design can adaptively adjust the degree of opening according to the size of the bag, ensuring that the bag opening is fully opened, allowing the material to fall smoothly into the filter screen by its own weight, avoiding material blockage caused by the bag opening being too small, improving feeding efficiency, and ensuring the smoothness of the feeding process.

[0019] The spring installed between the sliding plate and the clamping cross plate in the clamping component can adaptively adjust the clamping force according to the material of the bag and the characteristics of its contents. This ensures that the bag is firmly clamped while preventing damage to the bag or its contents due to excessive clamping force. It also reduces hard friction between the equipment and the bag, extends the service life of the equipment, and lowers maintenance costs. Attached Figure Description
