Title of Invention: Sealed Discharge Machine

Sealed discharge machine

[1] Technical field

[2] The present invention is a sealed discharge machine, in particular a sealed discharge device for powdery materials.

[3] Background Art

[4] The processing and reaction process of many products needs to be carried out in a sealed state. Since the sealing in the continuous feeding and discharging state cannot be carried out, the processing and reaction processes with such sealing requirements are generally used. The material is charged into the reactor, the reactor is closed, and the contents of the reactor are processed. Thereafter, after the reactor is opened, the reaction product is led out. As a result, the machining process can only be carried out intermittently.

[5] Summary of the invention

[6] The object of the present invention is to disclose a powder material sealing and discharging machine capable of achieving continuous sealed conveying.

[7] The invention comprises a delivery pipe with a discharge port, the opening of the discharge opening is located at the upper part of the delivery pipe, the opening of the discharge opening is located at the upper part of the conveying pipe, and the conveying pipe at the discharge opening is provided with a screw feeding mechanism. The technical scheme of the present invention is to form a material up-and-down by a screw feeder at a discharge port, and the material that has surged maintains its tendency to fall back, thereby closing the discharge port.

[8] In the conveying pipe of the present invention, only the forward spiral can be provided for feeding. However, in order to enhance the surge effect, the screw feeding mechanism should be composed of a forward and a reverse spiral mechanism, and the change of the positive and negative spirals should be set at the corresponding position with the discharge port. Moreover, there is preferably a certain spacing between the flights of the forward and reverse helical mechanisms. This material is pushed from both sides to the discharge port, which not only ensures the surge effect of the material, but also prevents the material from accumulating at the end of the delivery pipe.

[9] The reaction temperature in some reactors may be very high, and the discharged materials will carry a large amount of heat, in order to prevent the high temperature from affecting the conveying pipe and the conveying process, and the temperature after discharging the material is low, on the conveying pipe A cooling mechanism can be provided. Specifically, a cooling water jacket provided on the conveying pipe can be used.

[10] The conveying pipe can be placed obliquely, in particular, it can be a front high and a low low structure, but it can also be placed horizontally. Therefore, it is preferable to provide a screw feeding mechanism in the entire conveying pipe, and the conveying portion of the spiral piece and The reverse screw mechanism is disposed on the same spindle. [11] In order to ensure the accumulation effect of the material at the discharge port, an upward discharge pipe is arranged at the discharge port. In the present invention, the angle of inclination of the forward and reverse flights of the screw feeding mechanism is 30 to 120 degrees.

[12] The present invention achieves a problem that has not been solved in the past with a simple structure. This allows continuous operation of the sealing reaction process.

[19] This embodiment includes a downwardly inclined conveying pipe whose end is horizontal, the discharge port is disposed on the horizontal portion, and is located above the conveying pipe. Further, the horizontal portion is provided with a forward or reverse screw shaft which is extended from the end of the conveying pipe to be connected to the motor. The position of the screw shaft corresponds to the discharge port.

[20] Using this type of conveying pipe, the material can be piled up in the lower part, and then the material is pushed out from the discharge port by the screw shaft.

. The accumulated material forms a seal at the end of the pipe. The higher the stack height, the better the sealing effect.
