Technical Field

[0001] The utility model relates to the technical field of chemical equipment, and specifically, to a feeding device for mixing chemical raw materials. Background Art

[0002] Chemical raw material mixing equipment is used to uniformly mix different chemical raw materials in a specific proportion. It is widely used in industries such as chemical engineering, pharmaceuticals, and food to ensure the quality and stability of products. The mixing equipment usually includes a mixing tank, a feeding port, a mixer, and a driving device, and can achieve continuous or intermittent mixing, effectively improving production efficiency and reducing energy consumption. It is an essential and important link in chemical production.

[0003] However, in traditional mixing tanks, chemical raw materials are directly added by gravity, which easily leads to uneven addition of raw materials and affects the mixing effect, especially when adding large particles or viscous substances. In addition, when adding viscous or high-moisture chemical raw materials, it is more likely to clog or adhere and agglomerate at the feeding port of the mixing tank, resulting in unsmooth feeding and affecting the production progress.

[0004] The utility model aims to at least solve one of the technical problems existing in the prior art.

[0005] For this purpose, an object of the utility model is to provide a feeding device for mixing chemical raw materials. The feeding device for mixing chemical raw materials can drive the feed hopper to rotate through a first motor, and the scraper closely adheres to the inner wall of the rotating feed hopper to prevent adhesion when adding chemical raw materials and ensure smooth entry into the mixing tank.

[0006] To achieve the above object, the utility model provides the following technical solution: A feeding device for mixing chemical raw materials, including a mixing tank. The top of the mixing tank is communicated with a feed cylinder. The top of the feed cylinder is rotatably installed with a feed hopper through a bearing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 - 2, an embodiment of the present utility model provides a feeding device for mixing chemical raw materials, including: a mixing tank 1.

[0020] Among them, as Figures 1 - 3 shown, a feed cylinder 2 is connected to the top of the mixing tank 1. A feed hopper 3 is rotatably installed at the top of the feed cylinder 2 through a bearing 14. A first motor 4 is installed on the top of the mixing tank 1. A gear ring 9 is fixedly connected to the outer wall of the feed hopper 3. A gear 10 is fixedly connected to the rotating shaft of the first motor 4. The gear 10 meshes with the gear ring 9. During use, when adding chemical raw materials, the chemical raw materials enter the mixing tank 1 through the feed hopper 3 at the top of the mixing tank 1 for mixing. Among them, after the first motor 4 is started, it can drive the gear 10 to mesh with the gear ring 9 for transmission, so that the feed hopper 3 rotates, and the chemical raw materials passing through the feed hopper 3 can enter the feed cylinder 2 and the mixing tank 1 under the action of gravity.

[0021] Furthermore, referring to Figure 3 , two anti-backflow plates 11 are symmetrically and rotatably installed on the inner wall of the feed cylinder 2. A tension spring 12 is installed on the top of the anti-backflow plate 11. One end of the top of the tension spring 12 is fixedly connected to the inner wall of the feed cylinder 2. When granular or powdered chemical raw materials enter the mixing tank 1 through the feed cylinder 2, the anti-backflow plate 11 can be pressed down by its own weight to open the opening, and after the chemical raw materials pass through, the anti-backflow plate 11 can be quickly pulled by the tension spring 12 to close, preventing the chemical raw materials from flowing back.

[0022] In this embodiment, as Figures 2 - 4 shown, a fixing plate 13 is fixedly connected to the inner wall of the feed cylinder 2. A scraping plate 15 is detachably installed on the outer wall of the fixing plate 13. One side of the scraping plate 15 is attached to the inner wall of the feed hopper 3. When the feed hopper 3 rotates, the scraping plate 15 can closely adhere to the inner wall of the rotating feed hopper 3, ensuring that the chemical raw materials will not adhere to the inner wall of the feed hopper 3 and smoothly enter the mixing tank 1, preventing blockage of the feeding port and adhesion and caking phenomena when adding chemical raw materials.

[0023] Furthermore, referring to Figure 4 , a groove 17 is provided on the outer wall of the fixing plate 13. A convex plate 16 is fixedly connected to the outer wall of the scraping plate 15.

The scraping plate 15 can be inserted and installed in the groove 17 of the fixing plate 13 through the convex plate 16 and can be taken out of the groove 17 at any time, facilitating the separate replacement and maintenance of the scraping plate 15.

[0024] It should be noted that the scraping plate 15 is made of 304 stainless steel, and the stainless steel material has good corrosion resistance, high temperature resistance, and is convenient for cleaning.

[0025] As Figure 2As shown in the figure, a second motor 5 is installed on one side of the mixing tank 1. The rotating shaft of the second motor 5 is fixedly connected to a rod body 7. The rod body 7 penetrates through the mixing tank 1, and mixing blades 8 are fixedly connected to the outer wall of the rod body 7. The mixing tank 1 drives the rod body 7 and the mixing blades 8 to rotate by starting the second motor 5, so as to stir the chemical raw materials in the mixing tank 1 to achieve a mixing effect.

[0026] Specifically, a discharge valve 6 is connected to the bottom of the mixing tank 1, and the chemical raw materials can be discharged outward through the discharge valve 6 after being mixed.

[0027] Summarize and sort out the working steps of this solution according to the above technical solution: When the present utility model is used, when adding chemical raw materials, the chemical raw materials enter the mixing tank 1 through the feed hopper 3 at the top of the mixing tank 1 for mixing.

[0028] Among them, after the first motor 4 is started, it can drive the gear 10 to mesh with the gear ring 9 for transmission, so that the feed hopper 3 rotates. The chemical raw materials passing through the feed hopper 3 can enter the feed cylinder 2 and the mixing tank 1 under the action of gravity, and the scraper 15 can closely adhere to the inner wall of the rotating feed hopper 3 to ensure that the chemical raw materials will not adhere to the inner wall of the feed hopper 3 and smoothly enter the mixing tank 1, preventing the feeding port from being blocked and caking during the addition of chemical raw materials, and increasing the cleanliness of the feeding port of the mixing equipment.
