Description

Technical Field

[0001] The invention belongs to the technical field of talcum powder production, and particularly relates to a talcum powder production device and a production method thereof. Background Art

[0002] Talc is a fine powder made by grinding talc ore. It is mainly used in cosmetics, medicine, food additives and industrial production. Its main ingredient is hydrated magnesium silicate, which has good hygroscopicity, lubricity and chemical stability. It should be noted that the production process of talc needs to strictly comply with environmental protection and safety regulations, because talc may contain trace amounts of asbestos, which is a known human carcinogen. Therefore, appropriate precautions must be taken when handling talc, such as wearing protective equipment to reduce the risk of inhaling dust. In addition, modern talc production usually undergoes strict testing to ensure that the product does not contain asbestos.

[0003] The production of talc includes multiple steps: mining and selection, crushing and screening, grinding and grading, drying, ultrafine grinding and classification, packaging and storage, etc. When talc is crushed, a large amount of talc is often required to be quickly added to the grinder. However, the large amount of talc added, if the crushing efficiency of the grinder is insufficient, will cause the talc to accumulate on the upper side of the crushing roller, causing congestion of the talc, resulting in its subsequent inability to be crushed, affecting the processing of subsequent steps, and affecting the final production of talc and the production efficiency and speed.

When a large amount of talc is accumulated in the crushing shell, the first crushing knife cannot crush the talc quickly. When a large amount of talc is accumulated, the overall pressure in the crushing shell will increase. The increase in pressure will push the pressed block to move into the placement groove, and the extrusion rod will move into the abutment groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. When talc needs to be crushed, it is added into the crushing shell through the adding groove, and then the talc is crushed by the first crushing knife. After a large amount of talc is accumulated in the crushing shell, the pressure in the crushing shell will inevitably increase sharply, and the increase in pressure will compress the force-bearing mechanism, and the force-bearing mechanism will drive the expansion mechanism to move, and the movement of the expansion mechanism will increase the distance between the two first crushing knives, making it easier for the talc to fall from it, and preventing the crushing shell from being blocked and accumulated by too much talc.

[0016] 2. When the expansion mechanism is working, it will drive the automatic closing mechanism to start, and the mechanism will close the adding slot to prevent talc from continuing to be added when the crushing shell is blocked. When the crushing shell is blocked, it can be digested by itself. When the blockage comes into contact, the expansion mechanism will shrink and the automatic closing mechanism will be closed. Then talc can be added to the adding slot, thereby improving the automation of the device. BRIEF DESCRIPTION OF THE DRAWINGS

When a large amount of talc is accumulated in the crushing shell 1, the first crushing knife 104 cannot crush the talc quickly. When a large amount of talc is accumulated, the overall pressure in the crushing shell 1 will increase. The increase in pressure will push the pressure block 109 to move into the placement groove 309, and the extrusion rod 310 will move into the abutment groove 3. The movement of the abutment groove 3 will squeeze and drive the expansion mechanism to move, and the movement of the expansion mechanism will drive the two The first crushing knives 104 are away from each other, so that the talc falls from between the two first crushing knives 104, reducing pressure and preventing blockage.

After the talc enters the crushing shell 1, the driving component drives the pressing mechanism as a whole to push the talc downward as a whole, thereby increasing the contact density between the talc and the first crushing knives 104 and improving its crushing effect.

A talcum powder production device according to claim 6, characterized in that: A lubrication groove (307) is provided on the inner wall of one side of the pulverizing shell (1), a lubrication plate (308) is slidably connected in the lubrication groove (307), one end of the lubrication plate (308) is fixedly connected to a movable rod (306), and the movable rod (306) movably penetrates the inner wall of one side of the movable groove (304) and is fixedly connected to one end of the extension rod (301).

8. A talcum powder production device according to claim 7, characterized in that: A horizontal groove (303) is provided on the lower inner wall of the movable groove (304), a horizontal block (302) is fixedly connected to the lower end of the extension rod (301), a limiting groove (312) is provided on one inner wall of the placement groove (309), and a limiting block (313) is fixedly connected to one end of the pressure block (109).

9. A method for producing talcum powder, characterized in that: A talcum powder production device as described in claim 8 is used, comprising the following steps: S1: When a large piece of talc needs to be crushed, it is added into the crushing shell (1) through the adding groove, and then crushed by the first crushing knife (104). When a large amount of talc is accumulated in the crushing shell (1), the first crushing knife (104) cannot quickly crush the talc. When a large amount of talc is accumulated, the overall pressure in the crushing shell (1) will increase. The increase in pressure will push the pressure block (109) to move into the placement groove (309). At the same time, the squeezing rod (310) will move into the abutting groove (3). The movement of the abutting groove (3) will squeeze and drive the expansion mechanism to move. The movement of the expansion mechanism will drive the two first crushing knives (104) to move away from each other, so that the talc falls from between the two first crushing knives (104), reducing the pressure and preventing blockage. S2: When the expansion mechanism drives the two first crushing knives (104) to move away from each other, the automatic door closing mechanism is activated, and the automatic door closing mechanism closes the adding slot to prevent talc from being added to the crushing shell (1) when it is blocked, thereby preventing the blockage from being aggravated; S3: After the talc enters the crushing shell (1), the driving assembly drives the entire pressing mechanism to push the talc downward as a whole, thereby increasing the contact density between the talc and the first crushing blade (104) and improving the crushing effect.
