Problems solved by technology

[0003] Existing pyrolysis equipment with electric heating as the main heating method, its main heating component is the heating rotor, the heating rotor includes a rotor disk, and many electric heating elements are arranged in the rotor disk, so more wires are needed for electric heating. The element supplies power, and because the electric heating element will rotate with the rotor disk, the wire will rotate or shake with the rotation of the rotor disk, which is prone to winding and friction. If the wire is entangled, the heating rotor will not be able to continue to rotate , causing failure; if friction occurs, the insulation layer of the wire is easily damaged, and the safety hazard is relatively large; and because of the high temperature, too many wires will affect heat dissipation, making the wire easy to heat up and be destroyed by temperature rise; the above problems make the It is very difficult to connect the electric heating element with the power supply, which is an engineering problem that needs to be solved urgently

Embodiment 1

[0051] This embodiment provides a rotor electric heating structure for pyrolysis equipment, see Figure 1-3 , including a rotor disk 7, the axial distribution of the rotor disk 7 has several circles of electric heating zones, the circumference of the electric heating zone is distributed with a number of electric heating elements 6, and one end of the electric heating elements 6 is penetrated to In the core hole of the rotor disc 7,

[0052] The electric heating structure also includes a hollow shaft 2, the hollow shaft 2 is arranged along the axial direction of the rotor disk 7, the outer wall of the hollow shaft 2 is adjacent to the inner wall of the core hole, and one end of the hollow shaft 2 is fixedly connected The rotating part of the slip ring box 1, the fixed part of the slip ring box 1 is connected to an external power supply, and a number of ring rows 5 are installed at intervals along the axial direction of the hollow shaft 2, and each ring row 5 corresponds to one ...

Embodiment 2

[0070] This embodiment provides an electric heating structure for the rotor of a pyrolysis equipment, which differs from Embodiment 1 in that, as Figure 10 As shown, each of the neutral wire rings 51 is connected to the rotating part through a first cable 31 , and each live wire ring 52 is electrically connected to the rotating part through a second cable 32 .

[0071] In this solution, each ring bar 5 needs two cables for connection, that is, the live wire ring 52 needs a cable 2 32 for connection, and the neutral wire ring 51 needs a cable 31 for connection. In this manner, it is also possible to communicate the external power source with the electric heating element 6 . The first cable 31 connected to the zero wire ring 51 and the second cable 32 connected to the live wire ring 52 are arranged in a circular misalignment in the hollow shaft 2 to provide installation space and reduce the cable one 31 and cable Two 32 mutual interference possibilities.

Abstract

The invention relates to a rotor electric heating structure of pyrolysis equipment, which is characterized in that a hollow shaft is arranged on the inner wall of a core hole of a rotor disc to serve as a mounting foundation, so that a ring row can be mounted corresponding to an electric heating area; a ring row is arranged to connect an electric heating element, so that the number of required cables can be reduced, the heat dissipation capability is improved, the friction possibility is reduced, and the cable damage possibility is reduced; sockets in one-to-one correspondence with the electric heating elements are arranged on the ring row, so that disassembly, installation and replacement are facilitated; a slip ring box is matched with the ring row to connect the power supply and the electric heating element, so that static and dynamic conversion of the cable can be realized, the cable, the ring row, the socket, the electric heating element and the rotor disc rotate integrally, the cable cannot be wound, and the rotor disc can rotate continuously. The electric heating element is safely and stably communicated with the power supply, continuous heating can be achieved, mutual interference with rotation of the rotor disc is avoided, and heating rotor pyrolysis equipment with electric heating as a main heating mode can be achieved.

Description

technical field [0001] The invention relates to the technical field of pyrolysis equipment, in particular to an electric heating structure for a pyrolysis equipment rotor. Background technique [0002] At present, pyrolysis technology has various heating methods such as open flame heating, high-temperature flue gas heating, electromagnetic heating, microwave heating, hammer mill heating, and heat transfer oil heating. These heating methods have their own advantages and disadvantages. Some pyrolysis effects are not good, and some It will cause secondary pollution, some are not safe, and some equipment is more complex and requires more investment and higher operating costs. The pyrolysis equipment with electric heating as the main heating method has the advantages of high efficiency, high standard, high safety and environmental protection. [0003] Existing pyrolysis equipment with electric heating as the main heating method, its main heating component is the heating rotor, t...
