Description

Technical Field

[0001] This utility model relates to the field of gasification furnace technology, and more specifically, to a bottom slag removal device for a gasification furnace. Background Technology

[0002] A gasifier, also known as a straw gasifier, environmentally friendly and energy-saving gasifier, straw gasifier, straw gasification furnace, household straw gasifier, environmentally friendly and energy-saving gasification furnace, etc., is a combustible gas produced by biomass through pyrolysis and thermochemical oxidation in a closed, oxygen-deficient environment. This gas is a mixed gas containing carbon monoxide, hydrogen, methane, etc., and is also called biomass gas. After the gasifier is used, the waste residue produced inside needs to be discharged.

[0003] A search revealed that utility model patent CN219824091U discloses a bottom slag cleaning device for a gasifier. This device includes a bottom receiving plate for receiving waste slag discharged from the gasifier. A connecting slot is located at the bottom of the gasifier, and a plug-in block is installed on the bottom receiving plate. The bottom receiving plate is connected to the gasifier through the assembly of the plug-in block and the connecting slot. A slag cleaning component is installed on the bottom receiving plate, again connected to the gasifier through the assembly of the plug-in block and the connecting slot. This device satisfies the assembly requirements of the slag cleaning device and the gasifier. When the gasifier discharges slag, the discharge port can be opened to discharge the waste slag onto the bottom receiving plate. The bottom receiving plate receives the waste slag, and then a moving toothed rake can be used to gather the waste slag into a side trough. The waste slag is then discharged and processed through the threaded opening on the side trough. However, the aforementioned patent still has the following shortcomings: although the bottom receiving plate can catch the waste slag discharged from the slag discharge port, other equipment is still needed to transport the waste slag, making it impractical. Therefore, we propose a bottom slag cleaning device for a gasifier. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a bottom slag cleaning device for a gasifier.

[0005] To solve the above problems, the present invention adopts the following technical solution: a bottom slag cleaning device for a gasification furnace, comprising a base plate, on which a plurality of first hydraulic cylinders are fixedly installed, and a receiving box is fixedly connected to the top of the plurality of first hydraulic cylinders.

A plurality of second hydraulic cylinders are fixedly installed on the other end of the receiving box. The output ends of the plurality of second hydraulic cylinders extend into the inner cavity of the receiving box and are fixedly connected to a push plate. The two sides of the push plate are in contact with the side wall of the receiving box, and the bottom surface of the push plate is in contact with the bottom surface of the inner cavity of the receiving box. A scraping mechanism is provided on the end face of the push plate.

[0006] As a preferred embodiment of this utility model, the scraping mechanism includes a movable groove formed on the end face of the push plate. A servo motor is fixedly installed at one end of the inner cavity of the movable groove. A reciprocating screw is fixedly connected to the output shaft of the servo motor. The end of the reciprocating screw is rotatably connected to one end of the inner cavity of the movable groove. A scraper is threaded onto the outer side of the reciprocating screw. The end of the scraper extends into the inner cavity of the receiving box. The top and bottom surfaces of the scraper are respectively in contact with the top and bottom surfaces of the inner cavity of the movable groove.

[0007] As a preferred embodiment of this utility model, the insertion mechanism includes multiple springs fixedly connected to the side of the receiving box and two through holes opened on the side of the receiving box. The ends of the multiple springs are fixedly connected to a pull plate, and two pins are fixedly connected to the pull plate. The ends of the two pins extend through the through holes to the inner cavity of the fixing hole, and the outer diameter of the pins is respectively in contact with the inner wall of the through hole and the fixing hole.

[0008] As a preferred embodiment of this utility model, a control panel is fixedly installed on the side of the receiving box, and a storage battery is provided on the bottom surface of the base plate.

[0009] As a preferred embodiment of this utility model, a pusher is fixedly installed at the other end of the receiving box.

The rubber elastic tubes are sleeved on the outside of the reciprocating screw and the servo motor.

[0011] Compared with the prior art, the advantages of this utility model are as follows: In this utility model, the self-locking casters drive the receiving box to move, so that the receiving box moves to below the slag discharge port of the gasifier. The first hydraulic cylinder drives the receiving box to move upward, so that the top surface of the receiving box is in contact with the bottom surface of the gasifier, so that the waste slag falling from the slag discharge port of the gasifier is caught and collected by the receiving box. After the slag is discharged, the self-locking casters can continue to push the device to move, so as to transport the waste slag, avoiding the problem of needing to use other equipment to transport the waste slag.

[0012] In this invention, when it is necessary to unload the waste residue in the receiving box, the pull plate is pulled to disengage the end of the pin from the inner cavity of the fixing hole, thereby releasing the fixing of the box door and opening the box door. The second hydraulic cylinder drives the push plate to move, and the push plate pushes the waste residue in the inner cavity of the receiving box out from the end of the receiving box, thereby unloading the waste residue and improving the practicality of the bottom slag cleaning device of the gasifier.

The end of the scraper plate 14 extends into the inner cavity of the receiving box 4. The top and bottom surfaces of the scraper plate 14 are respectively in contact with the top and bottom surfaces of the inner cavity of the moving groove 11.

[0024] In this embodiment, the inner wall of the moving groove 11 is used to limit the scraper 14, so that the scraper 14 can only move along the axial direction of the reciprocating screw 13.

[0025] For details, please refer to Figure 1 , Figure 3 and Figure 4 The insertion mechanism 7 includes multiple springs 20 fixedly connected to the side of the receiving box 4 and two through holes 19 opened on the side of the receiving box 4. The ends of the multiple springs 20 are fixedly connected to a pull plate 21. Two pins 22 are fixedly connected to the pull plate 21. The ends of the two pins 22 extend through the through holes 19 to the inner cavity of the fixing hole 6. The outer diameter of the pins 22 is in contact with the inner wall of the through holes 19 and the fixing hole 6, respectively.

[0026] In this embodiment, when the box door 5 is closed, the fixing hole 6 at the end of the box door 5 and the through hole 19 on the side of the receiving box 4 are aligned so that the pin 22 can be inserted into the through hole 19 and the receiving box 4 to fix the box door 5.

[0032] In this embodiment, the outer side of the reciprocating screw 13 is protected by a rubber elastic tube 15 to prevent waste residue from falling onto the reciprocating screw 13.

[0033] Working principle: In use, first, hold the push handle 18 and push the device to directly below the slag discharge port of the gasifier. Secure the device using the self-locking casters 3. Then, use the control panel 16 to control the first hydraulic cylinder 2 to move the receiving box 4 upwards, so that the top surface of the receiving box 4 is in contact with the bottom surface of the gasifier. When the gasifier discharges slag, open the slag discharge port below the gasifier, allowing the waste slag to fall into the inner cavity of the receiving box 4. Simultaneously, start the servo motor 12 to rotate the reciprocating screw 13. Through the threaded engagement between the reciprocating screw 13 and the scraper 14, the scraper 14 moves back and forth along the axial direction of the reciprocating screw 13, using the scraper 14 to scrape the slag falling into the receiving box 4. The waste residue in the chamber is scraped to make the cone-shaped waste residue piled up even. Then, after the waste residue in the gasifier is discharged, the slag discharge port of the gasifier is closed. At this time, the first hydraulic cylinder 2 drives the receiving box 4 to move down. The push handle 18 is held to make the self-locking caster 3 drive the device to move, so that the receiving box 4 loaded with waste residue moves to the waste residue treatment or centralized treatment area. Finally, the pull plate 21 is pulled to make the end of the pin 22 disengage from the inner cavity of the fixing hole 6, thereby releasing the fixation of the box door 5 so that the box door 5 can be opened. In addition, the second hydraulic cylinder 8 is started to drive the push plate 9 to move. The push plate 9 is used to push the waste residue in the inner cavity of the receiving box 4 out from the end of the receiving box 4 so that the waste residue can be discharged.
