Description
Technical field
The present invention relates to pneumatic conveyer, particularly relate to dilute phase positive-pressure conveying device.
Background technology
Pneumatic convey utilizes the energy of air-flow a kind of mass transport mode along air flow line conveying fine particle shape material in closed conduit, this mode of movement is not only easy to operate, also can do level, the conveying of vertical or direction of tilt, and also can heat material in course of conveying simultaneously, cool, physical operations or the chemical operation such as dry and air current classifying.According to the dense degree of material particles in delivery duct, pneumatic convey can be divided into gas material than the gentle material of relatively low two-phase transportation than relatively high diluted phase transport two kinds.Traditional dilute phase positive-pressure conveying device, comprise: feed intake feed bin, feed intake bin bottom discharging opening on 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, and blast pipe is connected with blower fan, 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 fed intake in feed bin constantly enters into transmitter by discharge pipe, air is constantly pressed into in transmitter from blast pipe by blower fan, thus 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: be connected by VERTICAL TUBE between rotovalve with transmitter inlet point, 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, thus produce the phenomenon of rotovalve gas leakage, the sealing property of whole feedway is reduced, affects the normal conveying of material.
Summary of the invention
The technical issues that need to address of the present invention are: provide a kind of and can effectively prevent the rotovalve on discharge nozzle stuck, and can ensure the dilute phase positive-pressure conveying device that material high-efficiency is carried.
For solving the problem, the technical solution used in the present invention is: dilute phase positive-pressure conveying device, comprise: feed intake feed bin, feed intake bin bottom discharging opening on 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, blast pipe is connected with blower fan, the discharging opening of transmitter is connected with delivery duct, be connected by tipping tube between rotovalve and the inlet point of transmitter, the upper orifice of tipping tube is connected with rotovalve, the lower nozzle of tipping tube is positioned at the inlet point 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 is formed along acclivitous inclined-plane, mass transport direction.
Further, aforesaid dilute phase positive-pressure conveying device, wherein, described blower fan is roots blower.
Beneficial effect of the present invention: owing to being connected by tipping tube between rotovalve and the inlet point of transmitter, so operationally can form negative pressure in tipping tube, makes blanking more unimpeded on the one hand; On the other hand, material can not return back in rotovalve, thus avoids the generation of rotovalve stuck phenomenon, ensure that the efficient conveying of material.
Accompanying drawing explanation
Fig. 1 is the structural representation of dilute phase positive-pressure conveying device of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing and optimum embodiment, the present invention is described in further details.
As shown in Figure 1, dilute phase positive-pressure conveying device, comprise: feed intake feed bin 1, the discharging opening bottom the feed bin 1 that feeds intake is 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 is connected with blast pipe 6, blast pipe 6 is connected with roots blower 7, compared with common blower fan, the outlet pressure of roots blower is higher, more efficiently can carry out mass transport.The discharging opening of transmitter 4 is connected with delivery duct 8, in the present embodiment, be connected by tipping tube 5 between rotovalve 3 with transmitter 4, 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 is along acclivitous inclined-plane, mass transport direction.
Principle of work of the present invention is as follows: when carrying out mass transport, open rotovalve 3, the material fed intake in feed bin 1 constantly enters into transmitter 4 by discharge pipe 2, air is constantly pressed into in transmitter 4 from blast pipe 6 by roots blower 7, thus constantly the material in transmitter 4 is delivered to next station by delivery duct 8.Owing to being connected by tipping tube 5 between rotovalve in the present embodiment 3 with the inlet point on transmitter 4, 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 formation is along acclivitous inclined-plane, mass transport direction, during such work, air in tipping tube 5 forms negative pressure, make blanking more unimpeded, material also can not return back in rotovalve 3, effectively prevent the generation of rotovalve stuck phenomenon, thus ensure that the efficient conveying of material.
