Description

Technical Field

[0001] This utility model relates to the field of antioxidant grinding technology, specifically a low-temperature grinding device for antioxidant powder production. Background Technology

[0002] Antioxidants are substances that prevent the adverse effects of oxygen. They are a class of substances that help capture and neutralize free radicals. Grinding equipment is required in the production process of antioxidant powder.

[0003] Currently, some grinding equipment on the market includes, for example, a utility model patent with authorization announcement number CN222956545U that discloses a grinding device for feed antioxidant excipients. This device drives a grinding disc to rotate by starting a drive motor. The antioxidant excipients falling on the grinding disc are uniformly and finely ground after passing through the gap between the grinding disc and the grinding sleeve. They then fall onto a centrifuge table through the action of a guide hood. Larger antioxidant excipient particles have a shorter horizontal throwing distance and fall into the first storage chamber and are discharged through the first discharge pipe, while smaller antioxidant excipient particles have a longer horizontal throwing distance and fall into the second storage chamber and are discharged through the second discharge pipe. Grinding and screening are completed in one set of equipment. However, during the use of this device, as the temperature rises during the grinding process, the antioxidant powder is easily subjected to a thermal degradation reaction, thus becoming ineffective. Furthermore, unqualified larger antioxidant particles are separated out, requiring subsequent personnel to reintroduce them into the grinding shell for grinding, which is quite troublesome.

[0004] Therefore, we propose a low-temperature grinding equipment for the production of antioxidant powders to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in some current grinding equipment, as the temperature rises during the grinding process, the antioxidant powder is easily thermally degraded, thus becoming ineffective. Furthermore, larger, unqualified antioxidant particles are separated out, requiring subsequent re-introduction into the grinding shell for grinding, which is quite troublesome.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a low-temperature grinding device for producing antioxidant powder, comprising: a grinding box, wherein a grinding mechanism is provided inside the grinding box, and a guide pipe connected to the grinding mechanism is provided on the grinding box; a sieving cylinder is provided inside the grinding box; a collecting cylinder connected to the sieving cylinder is provided inside the grinding box; a feeding hopper is provided on the grinding box; and a discharge pipe sleeved with the guide pipe is provided at the bottom of the feeding hopper. The reflux system, located outside the grinding chamber, is used to guide the material in the collection cylinder into the feed pipe; The grinding mechanism includes an upper grinding disc and a lower grinding disc. The upper grinding disc is connected to a guide pipe, and the lower grinding disc is connected to the inner wall of the grinding box by multiple fixing rods. Cooling channels are provided in both the upper and lower grinding discs, and inlet pipes and outlet pipes are respectively connected to the two ends of the cooling channels.

[0007] Furthermore, the reflux system includes a material pump installed on the grinding chamber, a first reflux pipe is provided between the input end of the material pump and the bottom of the screening cylinder, and a second reflux pipe is provided between the output end of the material pump and the discharge pipe.

[0008] Furthermore, the screening cylinder is configured as a conical cylinder structure, with the upper opening of the conical cylinder connected to the inner wall of the grinding chamber, and the lower opening of the conical cylinder connected to the collecting cylinder.

[0009] Furthermore, the bottom of the collecting cylinder is configured as an inverted bucket structure.

[0010] Furthermore, the bottom wall of the grinding box is set as a slope, and a discharge pipe is provided near the bottom of the grinding box.

[0011] Furthermore, a drive motor is provided on the grinding box, a first gear is provided on the output shaft of the drive motor, and a second gear that meshes with the first gear is sleeved on the guide tube.

[0012] The beneficial effects of this utility model are as follows: By providing cooling channels in both the upper and lower grinding discs, and connecting inlet and outlet pipes at both ends of the cooling channels, cooling medium can be introduced into the cooling channels to cool and lower the upper and lower grinding discs, preventing the antioxidant powder from undergoing thermal degradation. By providing a reflux system on the outside of the grinding box, the material in the collection cylinder can be introduced into the feed pipe, allowing the material to enter the grinding mechanism for grinding through the feed pipe and guide pipe, eliminating the need for manual feeding and making it simple and convenient.

A second gear 19 meshing with the first gear 18 is sleeved on the guide pipe 2, which can guide the antioxidant material into the feed hopper 5. The antioxidant material will enter the grinding mechanism for grinding through the discharge pipe 6 and the guide pipe 2.

[0017] like Figures 1-2 As shown, the reflux system is located outside the grinding chamber 1 and is used to guide the material in the collection cylinder 4 into the feed pipe 6. The reflux system includes a material pump 13 installed on the grinding chamber 1. A first reflux pipe 14 is provided between the input end of the material pump 13 and the bottom of the screening cylinder 3, and a second reflux pipe 15 is provided between the output end of the material pump 13 and the feed pipe 6. After being screened by the screening cylinder 3, the antioxidant powder falls into the bottom of the grinding chamber 1, while the large particles of antioxidant material roll into the collection cylinder 4.
