Technical Field

[0001] The utility model relates to the technical field of tire pyrolysis, in particular to a tire pyrolysis oil and gas separation device. Background Art

[0002] Cracking of waste tire rubber is one of the most thorough methods of treating waste automotive rubber. Cracking does not emit pollutants, but can also recover fuel oil and carbon black, which is beneficial to environmental protection and resource utilization, has high economic value, and is considered to be one of the best ways to treat waste tires. There are three types of processes for cracking waste tires: thermal cracking, catalytic degradation, and microwave depolymerization.

[0003] Generally, the production process of a waste tire pyrolysis plant mainly includes four parts, including a raw material prefabrication system, a pyrolysis reactor system, a gas-oil recovery and separation system, and a solid recovery system. Among them, the oil-gas mixture produced by tire pyrolysis needs to be separated into gas and oil by a gas-oil recovery and separation system. The existing oil-gas separation device usually accelerates the oil-gas separation by rotating a stirring paddle to generate centrifugal force, and the stirring paddle is usually confined in the device, and the centrifugal range is limited. Therefore, a tire pyrolysis oil-gas separation device is proposed to solve the above problem. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a tire pyrolysis oil-gas separation device, which has the advantages of accelerating separation efficiency and the like, and solves the problem that the stirring paddle is usually restricted within the device and the centrifugal range is limited.

[0005] To achieve the above object, the utility model provides the following technical solution: a tire pyrolysis oil-gas separation device, comprising a frame, a separation tank is fixed on the frame, a feed pipe is connected to the side of the separation tank, an air outlet pipe and an oil discharge pipe arranged up and down are connected to the separation tank, and a stirring mechanism is also provided in the separation tank;

[0006] The stirring mechanism includes a cover plate fixed on the separation tank, a mounting frame fixed on the cover plate, movable plates that can move up and down are arranged on both sides of the mounting frame, driving motors are fixed on the two movable plates through connecting frames, and the output shaft of the driving motor is fixed with a stirring rod extending into the separation tank, and a stirring blade is fixed to the bottom end of the stirring rod. Transmission sprockets are rotatably provided at the bottom and top ends of both sides of the mounting frame, and transmission chains are mounted on the two transmission sprockets on the same side. The transmission chain can be autonomously transmitted, and the sides of the two transmission chains are respectively fixed on the corresponding movable plates.

[0007] Furthermore, a driving rod is rotatably provided at the bottom end of the mounting frame through a bearing, and both ends of the driving rod are fixed between two transmission sprockets at the bottom end of the mounting frame. A rotating motor is also fixed to the inner bottom wall of the mounting frame, and an output shaft of the rotating motor is fixed with a driving sprocket pressed on the inner side of the corresponding transmission chain.

[0008] Furthermore, a pair of clamping sprockets are installed on the mounting frame and are respectively pressed on the outsides of the two transmission chains.

[0009] Furthermore, the side of the separation tank is also connected to an overflow pipe.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0011] In the tire pyrolysis oil-gas separation device, after the oil-gas mixture enters the separation tank through the feed pipe, the stirring blades rotate in the separation tank to generate centrifugal force for the oil-gas mixture. The liquid oil mist is affected by the centrifugal force and collides with the inner wall of the separation tank to form liquid flowing downward, while the gas separated from the oil liquid and oil mist flows upward and is discharged through the gas outlet pipe of the separation tank.

[0012] The movable plate is arranged on the side of the mounting frame and can move up and down, so that the stirring blade can move up and down in the separation tank, thereby increasing the stirring range and further accelerating the separation efficiency of the oil-gas mixture.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 A tire pyrolysis oil and gas separation device in this embodiment includes a frame 1, a separation tank 2 is fixed on the frame 1, a feed pipe 3 and two air outlet pipes 4 located above the feed pipe 3 and symmetrically distributed with the center of the separation tank 2 as a reference are connected to the side of the separation tank 2, and an oil discharge pipe 5 is connected to the bottom end of the separation tank 2. The oil and gas mixture enters the separation tank 2 through the feed pipe 3, and the oil and gas are separated by the separation tank 2. The gas can be discharged through the air outlet pipe 4, and the liquid can be discharged through the oil discharge pipe 5 at the bottom of the separation tank 2. A stirring mechanism 6 is also provided in the separation tank 2, so that after the oil and gas mixture enters the separation tank 2, the liquid oil mist will be affected by centrifugal force and collide with the inner wall of the separation tank 2 to form liquid flowing downward, while the gas separated from the oil and oil mist flows upward and is discharged through the air outlet pipe 4 of the separation tank 2.

[0019] The side of the separation tank 2 is also connected with an overflow pipe 7 to prevent the liquid level from being too deep and affecting the separation effect of the oil-gas mixture.

[0020] The stirring mechanism 6 drives the oil-gas mixture to rotate, generating centrifugal force, which can accelerate the oil-gas separation efficiency. Figure 3 As shown, the stirring mechanism 6 includes a cover plate 601 fixed on the separation tank 2, a mounting frame 602 is fixed on the cover plate 601, two movable plates 603 are provided on both sides of the mounting frame 602, a connecting frame 604 is fixed on the two movable plates 603, a driving motor 605 is fixed on the connecting frame 604, an output shaft of the driving motor 605 is fixed with a stirring rod 606 having one end passing through and extending into the separation tank 2, a stirring blade 607 is fixed to the bottom end of the stirring rod 606, the output shaft of the driving motor 605 drives the stirring rod 606 to rotate, and the stirring blade 607 rotates in the separation tank 2 to generate centrifugal force for the oil-gas mixture, thereby accelerating the separation efficiency.

[0021] As a preferred mode, the movable plate 603 is arranged on the side of the mounting frame 602 and can move up and down, so that the stirring blade 607 can move up and down in the separation tank 2, thereby increasing the stirring range, thereby further accelerating the separation efficiency of the oil-gas mixture. The bottom and top ends of both sides of the mounting frame 602 are provided with transmission sprockets 608 through the rotation of the rotating shaft, and the two transmission sprockets 608 on the same side are sleeved with transmission chains 609. The sides of the two transmission chains 609 are respectively fixed on the corresponding movable plate 603, and the movable plate 603 can be driven to move up and down through the transmission of the transmission chain 609. In addition, a guide sleeve for the stirring rod 606 to move up and down is provided in the cover plate 601, and a sealing ring is provided in the guide sleeve to prevent the gas from leaking through the gap between the guide sleeve and the stirring rod 606 when the stirring rod 606 moves up and down.

[0022] The bottom end of the mounting frame 602 is provided with a driving rod 610 which rotates through a bearing. The two ends of the driving rod 610 are fixed between the two transmission sprockets 608 at the bottom end of the mounting frame 602, so as to realize the linkage of the two sets of transmission chains 609. The inner bottom wall of the mounting frame 602 is also fixed with a rotating motor 611. The output shaft of the rotating motor 611 is fixed with a driving sprocket 612 which is pressed on the inner side of the corresponding transmission chain 609. The output shaft of the rotating motor 611 drives the driving sprocket 612 to rotate, so as to drive the corresponding transmission chain 609 to transmit. Under the transmission action of the driving rod 610, the two sets of transmission chains 609 can rotate at the same time, and at the same time drive the movable plate 603 to move up and down.

[0023] In addition, a pair of clamping sprockets 613 are installed on the mounting frame 602 and are pressed on the outer sides of the two transmission chains 609 respectively, so as to increase the tension of the transmission chains 609 .

Under the guiding action of the limiting slider and the limiting slide rail, the movement of the movable plate 603 is more stable.

[0025] By adopting the tire pyrolysis oil-gas separation device and using a centrifugal rotation method, the gas-liquid separation efficiency of the oil-gas mixture can be fully improved. The specific separation method is as follows:

The stirring blade 607 rotates in the separation tank 2 to generate centrifugal force for the oil-gas mixture. The liquid oil mist is affected by the centrifugal force and collides with the inner wall of the separation tank 2 to form liquid flowing downward, while the gas separated from the oil mist flows upward and is discharged through the outlet pipe 4 of the separation tank 2. In addition, the output shaft of the rotating motor 611 drives the active sprocket 612 to rotate, which can drive the corresponding transmission chain 609 to transmit. Under the transmission action of the driving rod 610, the two sets of transmission chains 609 can rotate at the same time, and at the same time drive the movable plate 603 to move up and down, so that the stirring blade 607 can move up and down in the separation tank 2, thereby increasing the stirring range and further accelerating the separation efficiency of the oil-gas mixture.

The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
