Technical Field

[0001] This utility model relates to the field of material pyrolysis technology, specifically to a pyrolysis equipment gas and slag discharge spiral. Background Technology

[0002] Cracking technology is one of the effective means of treating waste materials. By cracking waste materials under high temperature, normal pressure, and with the help of catalysts, a variety of valuable products can be obtained, such as cracked oil, carbon black, and recyclable metals. For example, the waste tire pyrolysis refining process can convert waste tires into products such as primary diesel oil, realizing the recycling of resources.

[0003] However, the existing devices have the following problems:

[0004] In pyrolysis equipment, with the continuous increase in the size of pyrolysis furnaces, the continuous increase in pyrolysis output, and the continuous increase in service life, traditional oil and gas outlet sealing methods can no longer meet the needs in terms of processing, installation, and use, resulting in a series of production problems. For example, the cylinder diameter is too large, making it impossible to meet the processing concentricity requirements, and the equipment size is too large, making it impossible to meet the installation accuracy requirements, among other problems.

[0005] Therefore, in order to solve the above problems, a gas discharge and slag discharge spiral for pyrolysis equipment is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a gas and slag discharge spiral for pyrolysis equipment to solve the gas and slag discharge requirements of pyrolysis equipment mentioned in the background art.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-2 One embodiment provided by this utility model:

[0020] A pyrolysis equipment gas and slag discharge spiral includes an oil and gas connection pipe 1, a rotary joint 2 fixedly connected to the outer side of the oil and gas connection pipe 1, a bellows pipe 3 fixedly connected to the outer side of the rotary joint 2, a spiral shell 8 fixedly connected to the outer side of the bellows pipe 3, a first oil and gas outlet 4 fixedly connected to the upper part of the spiral shell 8, a second oil and gas outlet 5 fixedly connected to the upper part of the spiral shell 8, an inspection port 6 fixedly connected to the lower part of the spiral shell 8, a slag discharge port 7 fixedly connected to the lower part of the spiral shell 8, a spiral support 9 fixedly connected to the lower part of the spiral shell 8, bolt blades 10 movably connected to the inside of the spiral shell 8, a reducer 11 fixedly connected to the outer side of the spiral shell 8, and a connecting motor 12 fixedly connected to the outer side of the reducer 11.

[0021] Furthermore, a filter screen 101 is fixedly connected to the outer side of the oil and gas pipe 1, and an oil and gas connecting ring 102 is fixedly connected to the outer side of the oil and gas pipe 1. An oil and gas connecting bolt 103 is connected inside the oil and gas connecting ring 102, which can transport oil and gas into the device through the oil and gas pipe 1.

[0022] Furthermore, a corrugated connecting ring 301 is fixedly connected to the outer side of the corrugated pipe 3, and a corrugated connecting bolt 302 is fixedly connected inside the corrugated connecting ring 301, which can reduce the impact of vibration on the bolt.

[0023] Furthermore, a maintenance plate 602 is fixedly connected below the maintenance port 6, and a maintenance fixing plug 601 is fixedly connected to the outside of the maintenance plate 602, which enables the blade to be inspected.

[0024] Furthermore, a support plate 901 is fixedly connected to the lower part of the spiral support 9, and a connecting plate 902 is fixedly connected to the upper part of the spiral support 9, which can support the device.

[0025] Furthermore, the reducer 11 is internally connected to a connecting chain 1101, and the reducer 11 is externally fixedly connected to a support frame 1102, which enables forward and reverse rotation and speed adjustment.

[0026] Furthermore, a fixing ring 1201 is fixedly connected to the outer side of the connecting motor 12, and a motor connecting frame 1202 is fixedly connected to the outer side of the connecting motor 12, which can drive the blades.

[0027] Working Principle: During operation, the oil and gas inlet screen plate on the end face of the oil and gas pipe 1 effectively blocks the entry of impurities. A slag inlet is located on the side of the oil and gas pipe 1. The oil and gas pipe 1 and the rotating end of the rotary joint 2 are fixed together at the gas outlet of the main furnace and rotate together with it. The fixed end of the rotary joint 2 is connected to one end of the bellows 3. Due to the excellent sealing performance of the rotary joint 2, oil and gas leakage is prevented. The radial and axial adjustments of the bellows 3 compensate for deviations caused by processing and installation, ensuring continuous and stable operation of the equipment. The other end of the bellows 3 is connected to the large flange on the spiral casing 8. This spiral has two gas outlets, allowing for the installation of different subsequent equipment or serving as a backup. In use, the spiral is equipped with an inspection port 6 for periodic inspection of the spiral blades. The slag outlet 7 is located at the tail end of the spiral to reduce residue accumulation. The spiral blades are arranged in an eccentric structure to ensure smooth flow of oil and gas. During pyrolysis in the main furnace, the bolts reverse to push the residue in the oil and gas and the carbon black that has entered the spiral back into the main furnace. After pyrolysis is completed, the spiral rotates forward to transport the carbon black in the main furnace to the slag outlet 7 for collection. The driving part of the spiral has a reducer 11 and a connecting motor 12, which can rotate forward and backward and adjust the speed. This spiral can effectively solve key problems such as gas outlet sealing and residue blockage in pyrolysis equipment. The structure is simple and easy to install, and can effectively solve problems caused by production and installation, ensuring continuous operation of the equipment.
