[0002] Sludge is a biomass containing a large number of microorganisms. The preparation of sludge biochar through thermochemical conversion at suitable temperature is a very promising method for sludge resource utilization. Sludge biochar is considered to be an excellent soil conditioner. Compared with drying and aerobic fermentation, heat treatment has more obvious advantages for sludge containing more toxic and harmful substances.

When the solution is in use, the motor drives the rotating shaft to rotate, so that the stirring rod stirs the sludge to ensure that the sludge is heated evenly. During the rotation of the rotating shaft, the scraper on the mounting block is driven to scrape the inner wall of the carbonization chamber.

Regarding the above technical solution, although this solution realizes the stirring of the sludge, it cannot heat the double layers from the inside and outside during carbonization, which is inconvenient when used.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 5 The utility model provides a technical solution: a biochar pyrolysis processing device, comprising a barrel body 1, a movable barrel 4 is movably installed inside the barrel body 1, and a lifting mechanism 5 is installed on the side of the movable barrel 4, and the lifting mechanism 5 is fixedly installed at the bottom of the barrel body 1, and a nitrogen pipe 2 and a heating pipe 3 are fixedly installed on the sides of the barrel body 1 respectively. A power mechanism 6 is fixed on the top of the barrel body 1, and the power mechanism 6 is a stirring motor. The motor drives the rotating rod 13 to rotate to stir the sludge. A feed hopper 7 and an exhaust pipe 8 are installed on the side of the power mechanism 6. A water tank 9 is movably installed on the exhaust pipe 8, and a displacement mechanism 10 is fixedly installed on the water tank 9. A movable column 11 is installed on the displacement mechanism 10, one end of the movable column 11 is fixed on the barrel body 1, and a one-way air outlet is fixedly installed on the exhaust pipe 8. An air outlet pipe 12 is fixed on the water tank 9. The lifting mechanism 5 and the displacement mechanism 10 are both linear reciprocating electric push rods. Driven by the displacement mechanism 10, the water tank 9 moves up and down to complete the height adjustment.

[0023] In this embodiment, a rotating rod 13 is rotatably installed inside the barrel body 1, a rotating column 14 is fixed on the rotating rod 13, a stirring rod 15 is welded on the rotating column 14, a scraper 16 is welded to one end of the rotating column 14, a cavity 17 is opened inside the barrel body 1, a spiral tube 18 is fixed inside the cavity 17, one end of the spiral tube 18 is connected to the heating tube 3, a limiting tube 20 is fixed on the side of the movable barrel 4, a heating mechanism 19 is fixedly installed inside the movable barrel 4, a partition plate 22 is fixed inside the water tank 9, a rubber plate 23 is fixedly installed between the partition plates 22, a sealing ring 21 is fixed inside the water tank 9, the sealing ring 21 cooperates with the exhaust pipe 8, the heating mechanism 19 is composed of an electric heating wire, and the electric heating wire generates high temperature when energized to heat the sludge.

[0024] When the device is in use, the sludge is passed from the inside of the feed hopper 7 into the space between the movable barrel 4 and the barrel body 1. After the sludge enters, the heating tube 3 is connected to the external steam pipe to provide high-temperature steam. The high-temperature steam moves through the spiral tube 18, and the spiral tube 18 quickly heats the barrel body 1. At the same time, the heating mechanism 19 is started, and the heating mechanism 19 heats the sludge from the inside. While heating, the power mechanism 6 is started, and the power mechanism 6 drives the rotating rod 13 to rotate. The rotating rod 13 drives the rotating column 14 to rotate between the movable barrel 4 and the barrel body 1. The sludge is stirred by the stirring rod 15 during rotation, so that the sludge is heated and carbonized in both directions. During the carbonization process, the waste gas generated by the sludge is discharged from the sludge. The exhaust gas is discharged from the exhaust pipe 8 and enters the water tank 9 from the exhaust pipe 8. The exhaust gas contacts with water, and the water adsorbs the particles in the exhaust gas. The particles are adsorbed and filtered before being discharged, reducing the impact on the air. In addition, the displacement mechanism 10 drives the water tank 9 to move up and down through the movable column 11. The up and down movement of the water tank 9 allows the exhaust holes to enter the top and bottom of the partition plate 22. The switching of the exhaust holes allows the exhaust gas to contact and filter with water layers at different positions, thereby extending the efficiency of water adsorption on particles. After the carbonization is completed, the barrel body 1 moves upward under the push of the lifting mechanism 5, and the movable barrel 4 is taken out separately from the inside of the barrel body 1. After taking it out, the rotation of the scraper 16 discharges the internal sludge from the inside of the barrel body 1.
