Description

Technical Field

[0001] The utility model relates to the technical field of sludge pyrolysis devices, and in particular to a highly efficient sludge pyrolysis treatment device. Background Art

[0002] Pyrolysis is a technology with a long history. The gasification of wood, peat and shale is pyrolysis. Depending on the chemical process used, pyrolysis is called dry distillation, coking, gasification and thermal decomposition. In recent years, pyrolysis has been increasingly concerned by all parties as an alternative technology to incineration. Sludge pyrolysis utilizes the thermal instability of organic matter in sludge and heats it under anaerobic conditions to cause thermal cracking of the organic matter. The organic matter is cracked according to its carbon-hydrogen ratio to form a gas phase (pyrolysis gas) and a solid phase (solid residue) with high utilization value. These products are easy to store, transport and use, providing an effective way to reduce, stabilize, harmlessly treat and recycle sludge.

[0003] When some existing sludge pyrolysis treatment devices are in use, most of them have a single stirring method, which makes the sludge heating uneven and the heat exchange efficiency low. Utility Model Content

[0004] The utility model aims to provide an efficient sludge pyrolysis treatment device in view of the defects of the prior art, so as to solve the problem that most of the existing sludge pyrolysis treatment devices have a single stirring mode during use, resulting in uneven sludge heating and low heat exchange efficiency.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A highly efficient sludge pyrolysis treatment device, comprising a device shell, the device shell is provided with a stirring mechanism, the stirring mechanism comprises a stirring motor arranged at one end of the device shell, the output end of the stirring motor extends to the inner cavity of the device shell and is provided with a connecting plate, the connecting plate is provided with a rotating shaft with one end rotatably connected to the inner side wall of the device shell, a plurality of evenly distributed rotating blades are provided on the outer surface of the rotating shaft, first fixing columns are symmetrically provided on the connecting plates on both sides of the rotating shaft, a plurality of evenly distributed first stirring rods are provided on the end surface of the first fixing column close to the rotating shaft, and the first stirring rods are gradually inclined outward from the end close to the first fixing column to the end away from the first fixing column;

[0007] Two symmetrically arranged second fixing columns are connected to the inner side wall of the device shell at one end away from the stirring mechanism. The second fixing columns are located between the rotating shaft and the first fixing columns. A plurality of second stirring rods are arranged on the outer end surface of the second fixing columns and extend obliquely between two adjacent first stirring rods.

[0008] As a preferred technical solution of the utility model, a feed pipe connected to the inner cavity is provided at the top of the device shell, and a discharge pipe connected to the inner cavity is provided at the bottom of the device shell, and a discharge valve is fixedly installed on the discharge pipe.

[0009] As a preferred technical solution of the utility model, a scraper is provided on the side of the first fixed column away from the first stirring rod, and is in contact with the inner wall of the inner cavity of the device shell. The scraper is connected to the first fixed column through a plurality of evenly distributed connecting columns.

[0010] As a preferred technical solution of the present utility model, a plurality of guide grooves are provided on the first fixing column and the second fixing column.

[0011] As a preferred technical solution of the utility model, the first fixing column and the first stirring rod and the second fixing column and the second stirring rod are both integrally formed structures.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] When in use, external sludge is injected into the device shell through the feed pipe, and the stirring motor is started to drive the rotating shaft and the first fixed column to rotate. The rotating blades on the rotating shaft and the first stirring rod on the first fixed column stir the sludge so that the sludge is evenly heated. During the stirring process, the scraper on the first fixed column can scrape off the sludge attached to the inner wall of the device shell to prevent the sludge from adhering to the inner wall of the device shell, resulting in uneven temperature inside the device shell, uneven heating of the sludge, and affecting the thermal decomposition effect of the sludge. At the same time, the sludge in the device shell is rotated with the rotating shaft and the first fixed column. When the sludge moves, part of the sludge is blocked by the second fixed column, thereby changing the movement direction of the part of the sludge, thereby improving the stirring effect on the sludge. The first stirring rod and the second stirring rod are arranged in coordination, thereby preventing the sludge from gathering between two adjacent first stirring rods or two adjacent second stirring rods, thereby further improving the stirring effect of the sludge. The utility model improves the pyrolysis efficiency of the sludge and the uniformity of sludge stirring, making the sludge heating more uniform, and at the same time can scrape off the sludge attached to the inner wall of the device shell, further improving the pyrolysis effect of the sludge.
