Detailed Description

Referring to fig. 1 to 3, the present invention discloses an exhaust device, which includes a hopper 10, wherein a partition plate 20 is disposed inside the hopper 10 and is divided into a material cavity 11 and an exhaust cavity 12 which are distributed transversely by the partition plate 20; the hopper 10 is also provided with a feed inlet, an exhaust port 30 and a downward connecting port 40; the feed inlet communicates the material cavity 11 with the outside; the connecting port 40 is respectively communicated with the bottom ends of the exhaust cavity 12 and the material cavity 11 and is used for being communicated with an inlet 71 of the external rotary valve; the exhaust port 30 communicates the exhaust chamber 12 with the outside.

On the basis of the structure, during the use, with the import 71 intercommunication of connector 40 and outside rotary valve, the material gets into in the material chamber 11 through the feed inlet, start outside rotary valve 70, and earlier through exhaust chamber 12 when making the baffle 72 of outside rotary valve rotatory, at this moment, the gas that drives through the baffle 72 of outside rotary valve is earlier through exhaust chamber 12 and accessible connector 40 gets into in the exhaust chamber 12, later gaseous through gas vent 30 discharge, so, exhaust chamber 12 is discharged to the gaseous majority between the baffle 72 of outside rotary valve, avoid gaseous at connector 40 department to hold the material, the baffle 72 of outside rotary valve then can receive the material smoothly when getting into material chamber 11, avoid appearing the phenomenon that the delivery volume is not enough.

The upper part of the exhaust cavity 12 of the embodiment is also communicated with the material cavity 11, so that air between the exhaust cavity 12 and the material cavity 11 can be circulated, and part of gas entering the material cavity 11 can also enter the exhaust cavity 12 and then be exhausted; in this case, even if the gas in the exhaust chamber 12 enters the material chamber 11, the hopper 10 has a sufficient space and the gas mostly flows upward, so that the gas can be prevented from being collected at the connection port 40.

In order to avoid the influence of the gas entering the material cavity 11 from the exhaust cavity 12 on the material, the material pipe 50 of the embodiment extends into the material cavity 11 through the feed inlet, and an outlet is formed at the bottom end of the material pipe 50 and is lower than the part where the exhaust cavity 12 is communicated with the material cavity 11, so that the discharge position of the material pipe 50 is lower than the part where the exhaust cavity 12 is communicated with the material cavity 11, and the influence can be reduced; it should be noted here that the material pipe 50 is accessible for material, i.e. the material pipe 50 is provided with an inlet.

The part of the material pipe 50 of this embodiment that is located outside the material cavity 11 is provided with the first connecting flange 60, and the first connecting flange 60 is convenient for the material pipe 50 to be connected with outside material storehouse 100, reduces the installation degree of difficulty.

The bottom end of the partition plate 20 of this embodiment extends out of the connection port 40 and can be tangent to the end of the baffle 72 of the external rotary valve, so that the partition plate 20 is arranged at the lowest position to block the gas driven by the external rotary valve 70 from entering the material chamber 11 through the exhaust chamber 12 as far as possible.

Aiming at the external rotary valve 70 with exhaust, the gas guide tube 90 is further included in the embodiment, one end of the gas guide tube 90 is used for being communicated with the external rotary valve 70, and the other end of the gas guide tube 90 is communicated with the material cavity 11, so that materials exhausted along with gas can be guided back to the material cavity 11 through the gas guide tube 90, and material waste is avoided; from above, double exhaust is realized.

The second connecting flange 80 is arranged at the connecting port 40 of the embodiment, and the second flange plate is connected with the external rotary valve 70, so that the installation difficulty is reduced.

The embodiment also discloses feeding equipment for positive pressure conveying, which comprises a rotary valve 70 and the exhaust device, and is characterized in that the connecting port 40 is communicated with the inlet 71 of the rotary valve, and the trough 73 of the rotary valve passes through the connecting port 40 in sequence and faces the exhaust cavity 12 and the material cavity 11 when rotating, so that the feeding equipment has the same technical effect as the exhaust device.

The partition plate 20 of this embodiment is inserted into the rotary valve 70 through the connection port 40 and is tangential to the rotation locus of the end surface of the baffle 72 of the rotary valve, so that the partition plate 20 is disposed at the lowest position to maximally prevent air from entering the material chamber 11 beyond the exhaust chamber 12.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
