Problems solved by technology

[0002] Tablet presses are used in the production of pharmaceutical solid preparation tablets. Due to static electricity during the production process, the produced plain tablets will absorb a certain amount of fine powder when they leave the tablet press. There is also a part of excess fine powder mixed with the tablet outlet and the plain tablet. If these fine powders are not separated, some fine powder will be adsorbed in the finished pharmaceutical packaging, which will affect the appearance quality of the product during packaging and pollute the packaging equipment and the air. , increase cleaning hours and costs, does not meet the requirements of pharmaceutical production GMP and environmental protection requirements
[0003] At present, there are generally two ways for the market and pharmaceutical manufacturers to separate the fine powder that is adsorbed or mixed into the plain tablet during the tableting process. One is to manually use a sieve to remove the fine powder and install it at the tablet outlet of the tablet machine. A shelf, a plate is placed on the shelf, and the sieve is placed in the plate. When the film fills one-third of the sieve, the operator lifts the sieve and shakes it left and right to stuff the dust into the plate. The disadvantage is that the work intensity of the employees increases. The dust generated during the powder sieving process is flying everywhere, and the dust in the air in the operating room will cause secondary air pollution, increase the burden of central air conditioning purification, and easily cause cross-contamination of drugs. It is difficult to pass the GMP inspection
The other is that the tablet outlet of the tablet press is connected to the tablet sieving machine. The advantage is that the fine powder removal effect is good, but the disadvantage is that some dust is also caused to fly during powder sieving, causing air pollution. At the same time, the tablet sieving machine relies on vibration to sieve powder, so the noise is large. The noise generated by the tablet press and vacuum cleaner during operation can reach more than 100 decibels. Production and operation in this environment for a long time will have a certain impact on the hearing of personnel. need frequent maintenance

Abstract

The invention relates to a device for removing dust in tablets of a tablet press. An interlayer is arranged in the middle of a rectangular tank body formed by stainless steel plates and divides the rectangular tank body into an upper cavity and a lower cavity. The interlayer is a 12-mesh stainless steel screen, and a detachable stainless steel cover is arranged on the upper cavity of the rectangular tank body. A bevel is arranged at the front end of the upper cavity, and the front end of the upper cavity is manufactured into a connector connected with the press, the rear end of the rectangular tank body is provided with a bevel, the upper cavity of the rectangular tank body is longer than the lower cavity, a stainless steel connector is welded and fixed to the lower portion of the rear end of the lower cavity, and the connector is used for being connected with a tablet press dust collector. The device has a good dust moving effect and is low in noise, low in cost, free of occupied area and low in fault rate, pollution caused by dust to air is effectively controlled, and cross contamination between medicines is effectively controlled.
