A kind of 200kg packing barrel drawing mechanism
Technical field
The utility model relates to a kind of drawing mechanism, especially a kind of 200kg packing barrel drawing mechanism.
Background technology
Along with the develop rapidly of chemical industry, all industrial flows and operation are all being tending towards simplifying.
At present, the a small amount of discharging of 200kg packing barrel is quite difficult to be controlled, the mode vacuumized generally is adopted to carry out taking out material, this Method compare is applicable to a large amount of dischargings, but the mode that discharging vacuumizes in a small amount is difficult to control in amount, therefore be just necessary the drawing mechanism developing a kind of applicable a small amount of discharging, through retrieval, do not find the same or analogous device of the utility model.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of drawing mechanism that can close discharging in a small amount.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of 200kg packing barrel drawing mechanism, and its innovative point is: comprise packing barrel body, also comprises a seal cover cap be threaded with packing barrel body discharging opening;
Described seal cover cap comprises top cover, interior pipe and outer tube, interior pipe and outer tube are welded on top cover, outer tube is positioned at below top cover, the screw thread matched with packing barrel body discharging opening is established outside outer tube, interior pipe lower end extends at the bottom of packing barrel bucket, interior pipe upper end exceeds top cover, top cover is also provided with a through hole be communicated with outer tube;
Described interior pipe upper end is connected with discharge pipe, and through hole docks with compressed air piping.
Further, below described top cover, outer tube is provided with seal ring.
Further, the diameter of described interior pipe is 1.8 ~ 2.3cm.
Further, the diameter of described outer tube is 2 ~ 3 times of discharge nozzle bore.
The utility model has the advantage of: the utility model changes traditional discharging that vacuumizes into Pneumatic material distributing, at the bottom of interior Guan Yansheng to packing barrel, through hole on top cover is connected with compressed air piping, open valve and start pressurization, liquid material will flow out from interior pipe under the effect of the pressure, just can be controlled the flow velocity of liquid material by pressurized air Valve controlling air pressure, finally complete discharging.
Seal ring can make the air-tightness of assurance device better, improves discharging efficiency.
The bore of discharge nozzle is between 1.8 ~ 2.3cm, and the bore of sealing valve is 2 ~ 3 times of discharge nozzle bore, and in the case, the ratio of air pressure and tapping flowrate reaches best, and it the most easily regulates.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model 200kg packing barrel drawing mechanism.
Detailed description of the invention
As shown in Figure 1: a kind of 200kg packing barrel drawing mechanism, comprises packing barrel body 1 and a seal cover cap.
Seal cover cap is threaded with packing barrel body 1 discharging opening, seal cover cap comprises top cover, interior pipe 2 and outer tube 3, interior pipe 2 is welded on top cover with outer 3 pipes, outer tube 3 is positioned at below top cover, and establish the screw thread matched with packing barrel body 1 discharging opening outside outer tube 3, interior pipe 2 lower end extends at the bottom of packing barrel body 1 barrel, interior pipe 2 upper end exceeds top cover, top cover is also provided with a through hole be communicated with outer tube, interior pipe upper end is connected with discharge pipe, and through hole docks with compressed air piping.
Below the top cover of the utility model device, outer tube is provided with seal ring, better ensure that the air-tightness of device.
The bore of interior pipe 2 of the present utility model is 1.8 ~ 2.3cm, and the bore of outer tube 3 is 2 ~ 3 times of interior pipe 2 bore, and in the case, the ratio of air pressure and tapping flowrate reaches best, and it the most easily regulates.
Its principle of work is: the utility model changes traditional discharging that vacuumizes into Pneumatic material distributing, at the bottom of interior Guan Yansheng to packing barrel, through hole on top cover is connected with compressed air piping, open valve and start pressurization, liquid material will flow out from interior pipe under the effect of the pressure, just can be controlled the flow velocity of liquid material by pressurized air Valve controlling air pressure, finally complete discharging.
