Description

An automatic wind supplement medicinal material crushing system against space negative pressure

technical field

The utility model relates to the field of medicinal material processing equipment, in particular to an automatic air supplement medicinal material crushing system for preventing space negative pressure.

Background technique

The medicinal material crushing system includes a feeding cabinet, a crushing machine, a dust collector, a screen box, a dust bag box, and an exhaust fan. When in use, start the exhaust fan, and the whole system forms a negative pressure. Under the action of negative pressure, the material enters the coarse crushing chamber in the pulverizer, which is embedded with flat pressing plate and curved tooth plate. The angled beating plate rotates at a high speed in the coarse crushing chamber, producing rapid relative movement during the period, and pushing the material outward, forming mutual impact between materials and repeated blows between the material and the beating plate and tooth plate, to achieve the ultimate crushing effect. Purpose. Then the two-stage separator is transported by wind to the finished product collector (screen box), and the dust-containing gas enters the dust bag box and is filtered by the filter bag. The dust is blocked on the outer surface and falls into the The receiving hopper is discharged, and the purified gas is discharged by the exhaust fan.

Due to the work of the exhaust fan, negative pressure is generated in the pulverizer, and the indoor air is drawn into the pulverizer from the air inlet. Since the pharmaceutical production workshop is a relatively closed space, the entire production workshop will also form a negative pressure. This not only does not take advantage of the normal production operation of the equipment, but also affects the health of the staff, and may also draw dust from other production workshops, resulting in excessive dust in the crushed material.

The dust-containing gas is pumped from the top of the dust collector into the dust bag box, and after being filtered, the clean gas is discharged through the exhaust fan.

The supplementary air duct can introduce outdoor air into the air inlet, so that the air introduced by the supplementary air duct can supplement the system. Since the other end of the supplementary air pipe protrudes outside the space where the pulverizer is located, negative pressure will not be formed in the production space where the system is located, ensuring the normal operation of the equipment and avoiding the situation that dust from other production workshops is pumped into the pulverizer , to ensure the cleanliness of crushed materials.

2. The filter air supply box can filter the air to ensure the cleanliness of the added air and reduce the situation of external dust entering the material.

3. The blower can draw the outside air into the pulverizer, further promote the flow of materials, and ensure that the pulverized materials can go from the pulverizer to the dust collector, and then settle from the dust collector to the screen box.

4. The oxidized honeycomb porcelain in the filter air box can remove carbon monoxide in the air, and the activated carbon layer can remove sulfur dioxide in the air, which improves the cleanliness of the air, avoids the contamination of medicinal raw materials, and ensures the quality of medicinal raw materials in the pulverizer.

5. After the filter in the screen box sieves the medicinal material powder, the fine enough powder is discharged from the discharge port, and the medicinal material powder with too large particle size flows into the pulverizer through the return port for re-crushing until The medicinal material powder is crushed to be fine enough.
