A rotary pyrolysis furnace

Abstract

The invention relates to a rotating pyrolysis furnace. The rotating pyrolysis furnace comprises a pyrolysis furnace body (1), a feeding bin (2), a discharging bin (3) and a bracket (4), wherein both the feeding bin (2) and the discharging bin (3) are arranged on the bracket (4), the pyrolysis furnace body (1) comprises an inlet (101), an inlet rotating piece (102), a working section (103), an outlet rotating piece (104) and an outlet (105), and the discharging bin (3) comprises a discharging bin body (300), a discharging port (301) and a discharging rotating interface (302); the inlet rotating piece (102) extends into the feeding bin (2) via a feeding rotating interface (203) and can rotate around the axis of the feeding rotating interface (203) of the feeding bin (2). A pressing block and a pressed block of the pyrolysis carbonization furnace are connected in the bulge and groove manner and play a sealing role, and compared with plane sealing, cooperation of the bulge and the groove has the better sealing effect.

Description

technical field [0001] The invention relates to a pyrolysis furnace, in particular to a rotary pyrolysis furnace for preventing gas exchange through the gap formed between a fixed part and a rotating body part. Background technique [0002] The invention of the application number 201510072445.5 published on June 24, 2015 discloses a sealing mechanism for preventing gas exchange. The present invention is a sealing mechanism for preventing gas exchange. block, a pressing block that rotates in clearance with the rotating part, and a pressing mechanism that is fixedly connected with the rotating part. The pressing block exerts pressure on the receiving block through the pressing mechanism; the receiving block is provided with a first sealing strip; the cavity of the pressing block Place the second sealing strip; the second sealing strip realizes the sealing of the first gap formed between the pressing block and the outer wall of the rotating part; the screw of the pressing screw...

AI Technical Summary

Problems solved by technology

[0004] (1) The spring of the pressing mechanism is inconvenient to assemble and disassemble due to its large expansion and contraction size, and it is prone to fatigue as the number of times of use increases, resulting in uneven pressure on the pressing block, which in turn leads to poor sealing performance

[0005] (2) During the use of the second sealing strip, it will be worn, and the gas will easily leak out from the worn port

[0006] (3) The pressing mechanism cannot directly provide space for installing thermal insulation cotton, resulting in a reduction in the thermal insulation performance of the furnace body

[0007] (4) During use, the first sealing strip is bound to be worn, and the sealing strip often needs to be replaced, which results in high cost of use

[0008] The above sealing mechanism for preventing gas exchange is applied to the rotary pyrolysis furnace, so that during the use of the pyrolysis furnace, the gas diffuses from the inside of the furnace to the outside of the furnace, because the pyrolysis gas in the pyrolysis furnace becomes more complex and the composition Instable, resulting in unreliable operation of the pyrolysis furnace and low safety factor
