Description

Technical Field

[0001] This utility model relates to the field of thermal desorption furnace technology, and in particular to a clogging-resistant main furnace device for thermal desorption of oil sludge. Background Technology

[0002] Thermal desorption of oily sludge is a treatment technology that separates pollutants from oily sludge through heating and enables resource utilization. During thermal desorption of oily sludge, a thermal desorption furnace can be used for thermal desorption treatment, and an agitator is installed in the thermal desorption furnace to prevent material accumulation. Before the oily sludge enters the thermal desorption furnace, it needs to be crushed to break large pieces of oily sludge into smaller particles, reduce the particle size of the material, improve the thermal desorption efficiency, and prevent the material from clogging in subsequent equipment. However, during the transportation of oily sludge, it will adhere to each other and form larger particles, which can easily cause blockage of the feed port when feeding it into the thermal desorption furnace. Utility Model Content

[0004] In order to achieve the above-mentioned utility model objectives, the first aspect of this utility model proposes an anti-clogging type oil sludge thermal desorption main furnace device, including a base and a furnace body, wherein a cutting mechanism is provided on the furnace body.

[0008] Furthermore, two annular grooves are formed in the middle of the outer wall of the rotating component, and one end of the transmission belt is respectively installed on the corresponding annular groove wall.

[0009] Furthermore, the bottom of the outer wall of the feeding cylinder is provided with several connecting ports, which penetrate the feeding cylinder from the outer wall of the feeding cylinder, and the corresponding transmission belt is located in the corresponding connecting port.

[0010] Furthermore, the bottom of the feeding cylinder has several outlets, one of which is located at the bottom of the inner wall of the feeding cylinder, and the other is located at the bottom of the feeding cylinder.

[0015] Beneficial effects:

[0016] The present invention relates to an anti-clogging type thermal desorption main furnace device for oil sludge, and the beneficial effects are derived based on the content of the claims.

[0017] 1. By setting up a cutting mechanism, in which the cutter is located at the bottom outlet of the feeding cylinder, the material conveyed to the bottom of the feeding cylinder is cut from the bottom of the inner wall and the outside of the bottom end of the feeding cylinder, breaking up the large clumps of oily sludge particles into smaller particles, which then enter the furnace body from the bottom outlet of the feeding cylinder. This can effectively reduce the blockage at the furnace body's feeding port.

[0018] 2. By setting up a spiral feeding rod, the second motor starts and drives the spiral feeding rod to rotate, conveying the oil sludge particles in the feeding cylinder to the bottom and out. This allows the oil sludge particles to be fed smoothly and creates a certain pressure on the top of the oil sludge particles, causing them to be squeezed out from the outlet of the feeding cylinder, making it easier for the bottom cutter to crush the oil sludge particles.

[0031] Reference Figures 1-5This utility model provides an anti-clogging type thermal desorption main furnace device for oil sludge, including a base 1 and a furnace body 2. A cutting mechanism is provided on the furnace body 2. The cutting mechanism includes a mounting frame 7, several feeding cylinders 8, rotating parts 18, cutters 19, a third motor 14, a turntable 15, and several transmission belts 16.

The rotating parts 18 are rotatably installed on the bottom end of the feeding cylinders 8. The cutters 19 are fixedly installed on the outer walls of both ends of the rotating parts 18. The third motor 14 is fixedly installed on the top end of the mounting frame 7. The output end of the third motor 14 extends into the interior of the mounting frame 7.

The two lugs of one of the transmission belts 16 are respectively installed on the outer walls of the turntable 15 and one of the rotating parts 18, and the transmission belt 16 is installed on the outer walls of the corresponding adjacent rotating parts 18.

[0032] The furnace body 2 is fixedly installed on the top of the base 1.

[0033] The bottom of the feeding cylinder 8 has several outlets, one of which, a cutter 19, is located at the bottom of the inner wall of the feeding cylinder 8, and the other cutter 19 is located at the bottom of the feeding cylinder 8; the cutter 19 rotates around the rotating part 18.

[0034] In this embodiment, a cutting mechanism is set up, in which the cutter 19 is located at the bottom outlet of the feeding cylinder 8. The material conveyed to the bottom of the feeding cylinder 8 is cut from the bottom end of the inner wall of the feeding cylinder 8 and the outside of the bottom end, breaking the large agglomerated oil sludge particles into smaller particles, which then enter the furnace body 2 from the bottom outlet of the feeding cylinder 8.

The connecting ports 17 penetrate the feeding cylinder 8 from the outer wall of the feeding cylinder 8, and the corresponding transmission belt 16 is located in the corresponding connecting port 17.

[0037] In this example, the corresponding transmission belt 16 is fitted into the annular groove 20 on the wall of the rotating component 18 to transmit power between the rotating components 18.

[0041] In this example, by setting up a spiral feeding rod 13, the second motor 11 is started, driving the spiral feeding rod 13 to rotate, conveying the oil sludge particles in the feeding cylinder 8 to the bottom and out. This allows the oil sludge particles to be fed smoothly, and also creates a certain pressure on the top of the oil sludge particles, causing the oil sludge particles to be squeezed out from the outlet of the feeding cylinder 8, making it easier for the bottom cutter 19 to crush the oil sludge particles.

[0043] In this example, one end of the air outlet 3 is integrally formed with a bracket to support one end of the stirring rod 5, and the other end of the air outlet 3 is connected to a pipe to discharge the water vapor and gasified petroleum hydrocarbons generated after the oil sludge particles are heated.

[0044] In this example, one end of the furnace door 21 is fixed to the furnace body 2 with screws.

[0045] In this example, heater 6 is an arc-shaped heating plate with an electric heating wire inside, which heats the furnace body 2 by generating heat.
