Description

Technical Field

[0001] The utility model relates to the technical field of iron-molybdenum catalyst processing, in particular to a uniform feeding structure of an iron-molybdenum catalyst tablet press. Background Art

[0002] Iron-molybdenum catalyst is a very effective catalyst discovered after extensive research. It is a synthetic catalyst that can effectively promote a certain chemical reaction to produce new substances or change the chemical properties of the original substances. In the production of iron-molybdenum catalyst, there is a tableting step that requires a rotary tablet press. The working principle of the rotary tablet press to press powdered raw materials into tablets is that the main motor drives the turntable to rotate through the transmission mechanism, and the reciprocating motion of the upper and lower punches is controlled under the cooperation of the force-applying mechanism and the upper and lower guide rails, and the cycle action is completed: filling materials-quantity-pre-pressing-main pressing-tablet discharging.

[0003] The raw materials of the existing tablet press are mostly added manually and transported to the material frame by the feed hopper. However, the raw materials are often not screened and filtered when added, and some raw materials that are not completely crushed will block the feed pipe and feed hopper, thereby hindering the feeding and affecting the normal operation of the tablet press.

[0004] To this end, Chinese patent CN218892269U discloses a feeding device for feeding a tablet press, which reduces the occurrence of blockage during the feeding process of the tablet press by setting a crushing structure in the feeding pipe; however, this device has the following disadvantages during use: no uniform feeding structure is set, resulting in uneven feeding speed of the raw material after crushing, affecting the subsequent tableting operation of the tablet press, resulting in unbalanced workload of the tablet press, and causing unstable operation or overload of the tablet press.
