Description

Technical Field

[0001] This utility model relates to the field of pyrolysis furnace technology, and in particular to a slag filter plate for pyrolysis furnaces. Background Technology

[0002] A pyrolysis furnace is a device used for the pyrolysis treatment of organic waste and other materials. A traditional pyrolysis furnace includes a discharge system to separately remove the solid residue, liquid products, and gaseous products from the furnace. Solid residue may require subsequent processing such as cooling and crushing; liquid products need to be collected and further purified; and gaseous products require purification, collection, or direct utilization.

[0003] Existing pyrolysis furnace discharge systems generally include a filtration device, such as the one described in application number "CN202223045250.6" and patent titled "Slag Filtration Device," which includes multiple filtration mechanisms and a support mechanism for supporting these multiple filtration mechanisms. Each filtration mechanism includes a support portion and a filtration section disposed on the lower side of the support portion. The support mechanism includes a support unit with multiple mounting ports, in which the multiple filtration mechanisms are respectively disposed. The filtration section can pass through the mounting ports, and the support portion can abut against the upper surface of the support unit to support the filtration mechanism.

[0004] However, this type of filtration device still has the following drawbacks: the modular filtration mechanism is still quite large, and the operation is very inconvenient when disassembling and cleaning; the internal reinforcing ribs of the filtration mechanism are set in a cross shape, but their structural stability is still insufficient. After long-term use, the filtration mechanism is prone to deformation, which leads to a larger gap between the filtration mechanism and the support mechanism, affecting the filtration effect.

The filter plate of the filter mechanism is modularly designed to improve the ease of cleaning the filter mechanism; the strengthening structure of the filter mechanism is improved to increase the strength of the filter mechanism and make its filtration performance more stable and reliable.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a slag filter plate for a pyrolysis furnace, comprising a modular support frame, the modular support frame being arranged in a square frame shape, and four reinforcing plates being provided inside the modular support frame. The first sides of the four reinforcing plates are respectively welded to the four corners of the modular support frame, and the reinforcing plates are respectively located at the diagonal positions of the modular support frame. The second sides of the four reinforcing plates are respectively welded together. The inner cavity of the modular support frame is divided by two adjacent reinforcing plates to form four triangular filter chambers. A triangular filter screen is movably installed at the bottom of each filter chamber. The side and bottom surfaces of the filter screen are respectively provided with screen holes, and the outer openings of the screen holes are formed with chamfers to facilitate the rinsing of the screen holes of the filter screen.

[0007] In a further technical solution, an opening is provided in the middle of the reinforcing plate, and two adjacent filter chambers are connected through the opening.

[0008] In a further technical solution, the bottom of the four inner walls of the module bracket are sequentially formed with guide slopes and limiting steps, and adjacent guide slopes and limiting steps are connected to each other; the bottom of the filter chamber is open to form a triangular opening, and the filter screen is embedded in the triangular opening.

[0009] In a further technical solution, the inclination angle of the guide ramp is 45 degrees to 70 degrees; the horizontal width of the guide ramp is 8 cm to 15 cm.

[0010] In a further technical solution, the width of the step surface of the limiting step is 5cm-8cm.

[0011] In a further technical solution, a hanging plate is welded to each side of the filter screen, and the top of the hanging plate is bent into a hook, which is hung on the bottom edge of the opening; a limiting flap is formed on the outer edge of the filter screen, and the limiting flap is connected to the limiting step to realize the movable connection of the filter screen.

[0012] In a further technical solution, a first gripper is welded to the middle position of the side plate near the outer side of the filter screen; a second gripper is welded to the corner near the inner side of the filter screen, the second gripper including a straight rod, the two ends of the straight rod being welded to the corresponding side plate respectively.

[0013] In a further technical solution, a hook opening is provided on the outer side of the reinforcing plate for hanging the module bracket.

[0014] In a further technical solution, the orifice of the sieve is formed with a flushing guide structure, which includes chamfers and flat angles from the outside to the inside, and the depth ratio between the chamfers and flat angles is 2:1 to 1.5.

[0015] The advantages of this invention compared to the prior art after adopting the above structure are: 1. The inner cavity of the modular support is divided into four independent triangular filter chambers by four reinforcing plates, with a triangular filter screen movably installed at the bottom of each filter chamber. This split design allows each filter screen to be disassembled independently, avoiding the cumbersome operation of disassembling and assembling the entire filter mechanism required by traditional integral filters, greatly simplifying the cleaning process, and making it more efficient for cleaning clogging the screen holes.

[0016] 2. The filter screen is connected to the bottom edge of the opening by hooks on the hanging plate and by a movable connection between the limiting flap and the limiting step, which enables quick assembly and disassembly, further improving the convenience of cleaning operations.

[0017] 3.
