The outer diameter of the push plate 109 fits the inner wall of the kettle body 102 and is used to clean the solid material in the kettle body 102. A conveying cylinder 110 is fixedly connected to the lower right part of the frame 101, and the right side of the conveying cylinder 110 is fixedly connected to the filter cylinder 103. The interior of the conveying cylinder 110 is conical and is used to guide the liquid. A first filter ring 111 is fixedly connected to the left side of the conveying cylinder 110, and a storage box 112 is fixedly connected to the middle of the bottom of the frame 101. The storage box 112 is communicated with the first filter ring 111, and a connecting pipe 113 is fixedly connected between the storage box 112 and the filter cylinder 103, which is used to drain the liquid in the filter cylinder 103 into the storage box 112. A spiral filter assembly is provided in the filter cylinder 103.

[0032] like Figure 2 、 Figure 7 and Figure 8 As shown, the spiral filter assembly also includes a fixing frame 201, which is fixedly connected to the side wall on the right side of the filter cartridge 103. The fixing frame 201 is fixedly installed with a second motor 202. A second filter ring 203 is fixedly connected to the filter cartridge 103. The output shaft end on the left side of the second motor 202 is fixedly connected to a spiral conveying frame 204. The spiral conveying frame 204 passes through the second filter ring 203 and is rotatably connected to the filter cartridge 103. The side wall of the second filter ring 203 is evenly opened with a number of openings in the circumferential direction for filtering the liquid.

[0033] like Figure 2 and Figure 9 As shown, it also includes a spiral conveying blade 301, which is rotatably connected to the inner side of the conveying cylinder 110. A conveying belt 302 is sleeved on the right side of the spiral conveying blade 301, and the upper part of the conveying belt is sleeved on the output shaft end of the second motor 202.

[0034] First, the outlet on the left side of the top of the kettle body 102 is connected to the external condensing equipment, and then the oil sludge material that needs to be pyrolyzed is loaded into the kettle body 102 through the feed port on the right side of the top of the kettle body 102. Then the reactor is started, and the inside of the kettle body 102 begins to heat and heat the material to decompose. The organic components in the oil sludge begin to soften and gradually turn into a gas or liquid state. The decomposed liquid material flows into the filter cartridge 103 through the outlet at the bottom left of the kettle body 102, and finally flows into the storage box 112 for storage through the connecting pipe 113 at the bottom of the filter cartridge 103. The gas after heating and distillation is discharged into the external condensing equipment through the outlet on the left side of the top of the kettle body 102 for condensation and storage. The solid material remaining after separation is still Then, a pyrolysis reaction is carried out inside the kettle body. After the initial separation of the materials is completed, the first motor 107 is started, and the first motor 107 drives the screw 108 to rotate, thereby driving the pushing plate 109 to move to the left, pushing the remaining solid materials inside the kettle body 102 to the left, and at the same time cleaning the materials inside the reactor, so that the solid materials pass through the outlet at the bottom left of the kettle body 102 and enter the filter barrel 103. Then, the second motor 202 and the hot air blower 104 are started, and the second motor 202 drives the spiral conveying frame 204 to rotate, thereby continuously conveying the solid materials that fall into the filter barrel 103 to the right in batches. In the process of the solid materials moving to the right, they pass through the second filter ring 203, and the solid materials sandwiched in the filter barrel 103 are The impure liquid material is filtered through the second filter ring 203 and flows into the filter cartridge 103, and then flows into the storage box 112 through the connecting pipe 113. At the same time, the hot air from the hot air blower 104 enters the filter cartridge 103 through the conveying pipe 105, so that the hot air flows from right to left, drying and separating the solid material in the second filter ring 203. The hot air after drying and separation moves to the return pipe 106 driven by the hot air, and flows back to the kettle body 102 through the guidance of the return pipe 106, and finally flows out to the external condensation equipment for condensation. The solid particles after the secondary separation are then transported to the right side of the filter cartridge 103 and fall into the lower side of the filter cartridge 103. The second motor 202 is driven by the conveyor belt 302 The liquid then flows to the left through the conveying cylinder 110, is filtered by the first filter ring 111, and finally flows into the storage barrel, while the separated solid particles are discharged through the opening on the left side of the conveying cylinder 110. In summary, through the cooperation of the fan and the spiral filter assembly, the oily sludge material is refined and separated step by step, the separation conditions are optimized step by step, the separation purity and quality are improved, and the material is circulated and separated through the reflux pipe 106, which improves the utilization rate of the separated material, reduces energy consumption, and reduces the waste of resources in the processing process.

[0035] Example 2

[0036] On the basis of embodiment 1, as shown in Figure 2 and Figure 10 It also includes a rotating frame 401 fixedly connected to the left side of the screw 108, and the rotating frame 401 is uniformly distributed with a push rod on one side in the circumferential direction, which is used to push the solid material in the cylinder to prevent the discharge port from being blocked.

[0037] In order to avoid the material from being blocked at the left bottom outlet of the kettle body 102 during the movement to the filter cylinder 103, thereby affecting the subsequent separation effect, the specific operation is as follows: after the material completes the initial separation in the kettle body 102, the screw 108 drives the push plate 109 to move to the left side, and the screw 108 drives the rotating frame 401 to rotate, and the rotating frame 401 pushes the solid material stagnated at the left discharge port of the kettle body 102 to dredge it. When the push plate 109 moves to the left bottom outlet of the kettle body 102, the first motor 107 immediately starts to drive the screw 108 to reverse, drives the push plate 109 to move to the right side, and resets. When the screw 108 reverses, the rotating frame 401 is driven to rotate again to dredge the left discharge port of the kettle body 102. In summary, through the cooperation of the screw 108 and the rotating frame 401, the material in the kettle body 102 can be dredged to prevent the discharge port from being blocked, and the flow of the equipment operation is ensured.

[0038] Embodiment 3

[0039] On the basis of embodiment 2, as shown in Figure 1 , Figure 2 , Figure 11 It also includes a sliding frame 501 slidingly connected to the right side upper portion of the kettle body 102, and a magnet 502 fixedly connected to the lower left side of the sliding frame 501, and the magnet 502 is magnetically attracted to the push plate 109.

[0040] In order to avoid that the non-pyrolyzed material enters into the kettle body 102 in the process of pushing the plate 109 to clean the kettle body 102, so that the reaction kettle cannot carry out subsequent pyrolysis work, the specific operation is as follows: when the pushing plate 109 moves to the left side, the magnet 502 and the sliding frame 501 are driven to move to the left side, and then the feeding port on the right side of the kettle body 102 is closed; along with the continuous movement of the pushing plate 109 to the right side, the pushing plate 109 is separated from the magnet 502, and the closing of the feeding port of the kettle body 102 is completed; when the pushing plate 109 completes the cleaning of the material in the kettle body 102, the pushing plate 109 is re-adsorbed with the magnet 502 in the process of resetting to the right side, so as to drive the sliding frame 501 to move to the right side, and the feeding port of the kettle body 102 is re-opened. In summary, through the cooperation of the pushing plate 109 and the sliding frame 501, the automatic opening and closing of the feeding port of the kettle body 102 is realized, the non-separated material is avoided from entering into the reaction kettle, the operation of the equipment is affected, and the safety and stability of the equipment are ensured.
