Abstract

The utility model discloses a kind of vacuum discharge device of closed cycle drying machine, including airtight cavity and vacuum pump, it is characterized in that the cavity upper end is docked by hose with drying machine lower end discharge port by the way that clip is closed, docked with middle turning barrel by the way that clip is closed the lower end of the cavity, exhausting-gas hole is both provided with the cavity and middle turning barrel, the exhausting-gas hole is equipped with exhaust filter core and drain tap, the vacuum pump is connected by vacuum hose with cavity upper end bleeding point, and the bleeding point is equipped with dust removal filter element.Material in drying machine is evacuated in discharging machine cavity by vacuum pump after opening, and is then shut off the drain tap that vacuum valve opens discharging machine, feed powder is dropped in middle turning barrel.The utility model have the advantages that efficiently, avoid material from being contaminated and avoid airborne dust.

Description

A kind of vacuum discharge device of closed cycle drying machine
Technical field
A kind of drug materials conveying equipment of this practicality, more particularly to a kind of vacuum discharge device.
Background technology
At present in pharmaceutical industry drug production process, material needs artificial bagging charging transport after drying machine is dried, this Process is inconvenient, inefficiency, and the pollution of material is be easy to cause in manual operation.In addition, artificial bagging leakproofness Not enough, airborne dust is easily produced, it is unfavorable to human body and medicine workshop environment.
Utility model content
Material transfer efficiency can be improved the technical problem to be solved by the present invention is to provide one kind, avoid people and material from connecing Touch the vacuum discharge device for producing secondary pollution.In order to solve the above-mentioned technical problem, the technical solution of the utility model is to provide A kind of vacuum discharge device, including airtight cavity and vacuum pump, cavity upper end feed inlet lead to drying machine lower end discharge port The closed docking of clip is crossed, cavity lower end discharge port is docked with middle turning barrel feed inlet by the way that clip is closed, and the cavity is with The upper end of turning barrel is equipped with the exhausting-gas hole being in communication with the outside.
Further, vacuum pump is connected by vacuum hose with cavity upper end bleeding point, and the bleeding point is equipped with elongated circle Tubular dust removal filter element.
Further, the vacuum pump is peripheral pump.
Further, the exhausting-gas hole at the top of the cavity and middle turning barrel is respectively arranged with exhaust filter core.
Further, the discharge port of the middle turning barrel lower end is equipped with valve, all goes out when material fills up middle turning barrel or material Valve can be closed when complete.
Compared with prior art, the beneficial effects of the utility model are as follows:
1st, solve the problems, such as that artificial draw operation is inconvenient, improve work efficiency.
2nd, it is not tight to solve device leakproofness, dust drifts the problem of causing secondary pollution in the air.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Embodiment
The technical scheme in the embodiment of the utility model will be explained in detail below, so that those skilled in the art The advantages of more intuitively understanding the utility model and feature.
The utility model embodiment includes:
As shown in Figure 1, a kind of vacuum discharge device, including airtight cavity 2 and vacuum pump 4, cavity upper end feed inlet is with doing Dry machine lower end discharge port is closed by clip 6 with middle turning barrel feed inlet by 5 closed docking of clip, cavity lower end discharge port The upper end of docking, the cavity and middle turning barrel is equipped with the exhausting-gas hole being in communication with the outside.Vacuum pump passes through vacuum hose and cavity Upper end bleeding point connection, the bleeding point are equipped with elongated cylindrical dust removal filter element.Exhausting-gas hole at the top of the cavity and middle turning barrel It is respectively arranged with exhaust filter core.The discharge port of the middle turning barrel lower end is equipped with valve, has all gone out when material fills up middle turning barrel or material When valve can be closed.
Including airtight cavity and vacuum pump, cavity upper end feed inlet and drying machine lower end discharge port are closed by clip Docking, cavity lower end discharge port are docked with middle turning barrel feed inlet by the way that clip is closed, the upper end of the cavity and middle turning barrel It is equipped with the exhausting-gas hole being in communication with the outside.
Further, vacuum pump is connected by vacuum hose with cavity upper end bleeding point, and the bleeding point is equipped with elongated circle Tubular dust removal filter element.
Further, the vacuum pump is peripheral pump.
Further, the exhausting-gas hole at the top of the cavity and middle turning barrel is respectively arranged with exhaust filter core.
Further, the discharge port of the middle turning barrel lower end is equipped with valve, and when material fills up middle turning barrel, valve is closed.
The operating procedure of the utility model is:Vacuum pump is opened by automatic valve, makes to produce negative pressure in airtight cavity, will Material in drying machine is evacuated in discharging machine cavity, is then shut off the drain tap that vacuum valve opens discharging machine, is fallen feed powder Fall in turning barrel, be so recycled to material and fill up middle turning barrel or material all to have gone out.
The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every The equivalent structure or equivalent flow shift made using the utility model description, is directly or indirectly used in other phases The technical field of pass, is equally included in the patent within the scope of the utility model.
