[0002] A Chinese patent with the application number 201921992407.1 discloses a sludge carbonization pyrolysis furnace device, which is characterized in that it includes a sludge incineration chamber, a low-oxygen and low-temperature pyrolysis chamber, and a high-temperature separator; it adopts advanced two-stage fluidized combustion, divides the combustion chamber into two parts, separated by a partition wall in the middle, the front part is the incineration chamber, and the rear part is the low-oxygen and low-temperature pyrolysis chamber. After the carbonized granular material is sent into the front incineration chamber, the coarse material is pyrolyzed and cracked in this section, and heat is released; the heated fine granular material automatically flows into the rear low-oxygen and low-temperature pyrolysis chamber from the overflow port on the middle partition wall. No fresh air is sent into this section, and the fine granular material undergoes thermal decomposition treatment in an oxygen-deficient state. Organic matter is converted into water vapor, non-condensable gas and carbon. During this process, no nitrogen oxides and sulfur oxides are generated, reducing the emission of initial pollutants, and 90% of heavy metals react with carbon and are converted into a crystalline state, playing a role in solidification. The above scheme has the following defects. When the existing sludge pyrolysis carbonization furnace is in use, the carbonized sludge will stick to the inner part of the furnace body, which is not convenient for taking and pushing, and is not convenient to use.

[0003] Therefore, a multi-stage furnace for sludge pyrolysis carbonization is provided to solve the above problems. Summary of the Utility Model

After the installation block is inserted into the installation groove, the fixing rods are inserted into the grooves on both sides of the installation groove, so as to fix the installation block inside the installation groove, and being convenient to fix.

[0013] Preferably, to solve the problem of convenient operation of the fixed rod, the two groups of fixed rods are symmetrically arranged. The two groups of fixed rods are slidably connected to the mounting block, and a spring is fixedly connected between the two groups of fixed rods. While the fixed rod slides inside the limiting rod, the fixed rod compresses the spring arranged on the side. Under the action of the spring rebound force, the fixed rod can easily return to its original state.

[0014] Beneficial effects

[0015] For this pushing mechanism, the servo motor drives the reciprocating lead screw to rotate between the furnace body and the connecting frame. The reciprocating lead screw is threadedly connected to the pushing plate. Thus, the pushing plate is forced to slide outside the limiting rod. By sliding the pushing plate inside the furnace body, it is convenient to push the sludge carbonized in the furnace body. The operation is simple and fast, saving manpower and being easy to use.

[0016] For this sealing mechanism, by rotating the sealing door and pressing the two groups of fixed rods, while the two groups of fixed rods slide inside the mounting block, the fixed rods compress the springs arranged on the side. When the sealing door rotates and inserts the mounting block into the mounting groove, under the action of the spring rebound force, the fixed rods are inserted into the slots of the mounting groove, thereby fixing the mounting block inside the mounting groove. In this way, the sealing door can be sealed outside the opening of the furnace body. The sealing gasket arranged on the side of the sealing door is inserted into the sealing groove. By setting the sealing door and the sealing gasket, the furnace body can be sealed, which is convenient to open and seal and easy to use. Brief description of the drawings
