Description

Technical Field

[0001] This utility model relates to the technical field of solid waste pyrolysis, specifically a filtration and slag discharge device in solid waste pyrolysis equipment. Background Technology

[0002] Solid waste pyrolysis equipment is a specialized device for treating solid waste. Its main function is to convert organic solid waste into smaller molecules through pyrolysis technology, achieving harmlessness, volume reduction, and resource utilization. This equipment is widely used in the treatment of solid waste such as waste tires, plastics, oil sludge, and hazardous waste.

[0003] Solid waste pyrolysis equipment typically employs thermal pyrolysis processes under low-temperature, slightly positive-pressure, and anaerobic or oxygen-free conditions. This process uses high-temperature heating to decompose organic molecules into smaller molecules. For example, thermal pyrolysis equipment for coal tar residue has been successfully applied to the resource recovery of coal tar residue. Furthermore, microwave pyrolysis technology is also used in hazardous waste treatment, using microwave energy to break down large organic molecules into smaller compounds.

[0004] In existing solid waste pyrolysis equipment, the ash and slag produced by pyrolysis in the furnace are usually discharged after the pyrolysis is completed. Therefore, the pyrolysis in the furnace cannot continue to work. In order to ensure the normal operation of pyrolysis in the furnace, it is necessary to stop the machine at regular intervals to remove the ash and slag in the furnace, which reduces the pyrolysis efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a filtration and slag discharge device in a solid waste pyrolysis equipment to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A filtration and slag discharge device in a solid waste pyrolysis equipment is installed inside a pyrolysis furnace. The pyrolysis furnace includes a furnace body and a first furnace cover and a second furnace cover that can be detachably installed at both ends of the furnace body. The filtration and slag discharge device includes a slag filter assembly installed on the second furnace cover. The slag filter assembly includes a sealing plate that can abut against the inner end of the second furnace cover and multiple sets of connecting parts arranged along the circumference of the sealing plate.

[0008] It also includes a discharge component, one end of which passes through the through groove formed by the second furnace cover and is rotatably connected to the sealing plate. When the discharge component is controlled to move toward the furnace body, the sealing plate releases the sealing state of the through groove, and the ash and slag enter the discharge component through the filter groove formed between two adjacent connecting components and are discharged to the outside.

[0009] The filtration and slag discharge device in the solid waste pyrolysis equipment as described above: the connecting member includes a slider that is slidably disposed on the inner end face of the second furnace cover, a connecting rod is hinged on the slider, and the end of the connecting rod away from the slider is hinged to the sealing plate.

[0010] The filtration and slag discharge device in the solid waste pyrolysis equipment described above: a plurality of strip grooves are formed on the inner end face of the second furnace cover, which are arranged radially along the sealing plate, and a strip block is provided on the slider to slide in cooperation with the strip grooves.

[0011] The filtration and slag discharge device in the solid waste pyrolysis equipment described above: the discharge component includes a telescopic cylinder, one end of which passes through the second furnace cover and is rotatably connected to the sealing plate, and an auger is provided inside the telescopic cylinder, and the auger is driven to rotate by a motor fixedly installed on the telescopic cylinder.

[0012] The filtration and slag discharge device in the solid waste pyrolysis equipment described above: a guide trough is provided on the upper end of the cylinder wall at one end of the telescopic cylinder that penetrates the second furnace cover.

[0013] The filtration and slag discharge device in the solid waste pyrolysis equipment as described above: The filtration and slag discharge device in the solid waste pyrolysis equipment further includes a moving pusher, and the moving drive can control the telescopic cylinder to move toward the furnace body.

[0014] The filtration and slag discharge device in the solid waste pyrolysis equipment described above: a pusher plate with a spiral distribution is provided on the inner wall of the furnace body, and the end of the pusher plate faces the position of the sealing plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By controlling the discharge component to move towards the furnace body, the discharge component squeezes the sealing plate, thereby releasing the sealing plate from the through groove on the second furnace cover. When the sealing plate is squeezed by the discharge component, one end of the connecting component is pulled by the sealing plate and moves synchronously with the sealing plate, while the other end moves linearly along the radial direction of the sealing plate, so that the sealing plate and multiple connecting components are distributed in an umbrella shape. The filter groove formed between two adjacent connecting components can filter the ash and slag in the furnace body. The filtered ash and slag enter the discharge component and are discharged to the outside. Under normal pyrolysis operation of the furnace body, it can continuously filter and discharge the ash and slag in the furnace body, while the furnace body can always maintain a sealed state.
