Description
Technical field
The utility model relates to pneumatic conveyer, relates in particular to dilute phase positive-pressure conveying device.
Background technology
It is to utilize the energy of air-flow in closed conduit, along air flow line, to carry a kind of mass transport mode of fine particle shape material that air-flow is carried, this mode of movement is not only easy to operate, also can do the conveying of level, vertical or direction of tilt, and also can be simultaneously in course of conveying to material heat, physical operations or the chemical operation such as cooling, dry and air current classifying.Dense degree according to material particles in delivery duct, air-flow conveying can be divided into gas material and carry two kinds than the relatively low close relatively high dilute phase of gentle material ratio of carrying mutually.Traditional dilute phase positive-pressure conveying device, comprise: feed bin feeds intake, feed intake on the discharging opening of bin bottom and be connected with discharge pipe, the lower end of discharge pipe is provided with rotovalve, rotovalve is connected by VERTICAL TUBE with the inlet point on transmitter, transmitter admission port one end is connected with blast pipe, is connected with blower fan on blast pipe, and the discharging opening of transmitter is connected with delivery duct.The principle of work of above-mentioned dilute phase positive-pressure conveying device is as follows: open rotovalve, the material feeding intake in feed bin constantly enters into transmitter by discharge pipe, blower fan is constantly pressed into air to transmitter from blast pipe, thereby constantly the material in transmitter is delivered to next station in delivery duct.The shortcoming of above-mentioned dilute phase positive-pressure conveying device is as follows: between rotovalve and transmitter inlet point, by VERTICAL TUBE, be connected, air in VERTICAL TUBE easily forms malleation and returns back in rotovalve, so not only can produce resistance to blanking, and partial material can accumulate in rotovalve along with air revolution, cause rotovalve stuck, thereby produce the phenomenon of rotovalve gas leakage, the sealing property of whole feedway is reduced, affect the normal conveying of material.
Utility model content
The utility model technical issues that need to address are: provide a kind of and can effectively prevent that the rotovalve on discharge nozzle is stuck, and can guarantee the dilute phase positive-pressure conveying device that material high-efficiency is carried.
For addressing the above problem, the technical solution adopted in the utility model is: dilute phase positive-pressure conveying device, comprise: feed bin feeds intake, feed intake on the discharging opening of bin bottom and be connected with discharge pipe, the lower end of discharge pipe is provided with rotovalve, rotovalve is connected with the inlet point on transmitter, transmitter admission port one end is connected with blast pipe, on blast pipe, be connected with blower fan, the discharging opening of transmitter is connected with delivery duct, between the charging material mouth of rotovalve and transmitter, by tipping tube, be connected, the upper orifice of tipping tube is connected with rotovalve, the lower nozzle of tipping tube is positioned at the feed opening of transmitter, the body of tipping tube turns forward along mass transport direction from top to bottom, the bore of the upper orifice of tipping tube is less than the bore of lower nozzle, and lower nozzle forms along the acclivitous inclined-plane of mass transport direction.
Further, aforesaid dilute phase positive-pressure conveying device, wherein, described blower fan is roots blower.
The beneficial effects of the utility model: be connected by tipping tube between the inlet point due to rotovalve and transmitter, can form negative pressure in tipping tube like this when work, make blanking more unimpeded on the one hand; On the other hand, material can not return back in rotovalve, thereby avoids the generation of rotovalve stuck phenomenon, has guaranteed the efficient conveying of material.
Accompanying drawing explanation
Fig. 1 is the structural representation of dilute phase positive-pressure conveying device described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and optimum embodiment, the utility model is described in further details.
As shown in Figure 1, dilute phase positive-pressure conveying device, comprise: the feed bin 1 that feeds intake, on the discharging opening of feed bin 1 bottom that feeds intake, be connected with discharge pipe 2, the lower end of discharge pipe 2 is provided with rotovalve 3, rotovalve 3 is connected with the inlet point on transmitter 4, transmitter 4 admission port one end are connected with blast pipe 6, are connected with roots blower 7 on blast pipe 6, compare with common blower fan, roots blower to go out atmospheric pressure higher, can carry out more efficiently mass transport.The discharging opening of transmitter 4 is connected with delivery duct 8, in the present embodiment, between rotovalve 3 and transmitter 4, by tipping tube 5, be connected, the upper orifice 51 of tipping tube 5 is connected with rotovalve 3, the lower nozzle 52 of tipping tube 5 is positioned at the inlet point of transmitter 4, the body of tipping tube 5 turns forward along mass transport direction from top to bottom, and the bore of the upper orifice 51 of tipping tube 5 is less than the bore of lower nozzle 52, and lower nozzle 52 formation are along the acclivitous inclined-plane of mass transport direction.
Principle of work of the present utility model is as follows: when carrying out mass transport, open rotovalve 3, the material feeding intake in feed bin 1 constantly enters into transmitter 4 by discharge pipe 2, roots blower 7 is constantly pressed into air to transmitter 4 from blast pipe 6, thereby constantly the material in transmitter 4 is delivered to next station by delivery duct 8.Due between rotovalve in the present embodiment 3 and inlet point on transmitter 4, by tipping tube 5, be connected, the body of tipping tube 5 turns forward along mass transport direction, the bore of the upper orifice 51 of tipping tube 5 is less than the bore of lower nozzle 52, and lower nozzle 52 forms and is along the acclivitous inclined-plane of mass transport direction, while working like this, air in tipping tube 5 forms negative pressure, make blanking more unimpeded, material can not return back in rotovalve 3 yet, effectively avoid the generation of rotovalve stuck phenomenon, thereby guaranteed the efficient conveying of material.
