A rapid steam supply auxiliary device for boilers in operation

Abstract

This utility model discloses a rapid steam supply auxiliary device for a boiler, comprising a support frame fixedly connected to the bottom of the combustion furnace surface. A hydraulic rod is fixedly connected to the bottom of the inner cavity of the support frame, and a placement plate is detachably connected to the telescopic end of the hydraulic rod. Multiple support bars are fixedly connected to the top of the placement plate. A connecting frame is fixedly connected to the bottom of the combustion furnace, and insertion rods are fixedly connected to the four corners of the top of the placement plate. When slag needs to be cleaned, the placement plate is moved downward by the hydraulic rod, and guided by the insertion rods sliding on the inner surface of the insertion holes, thereby creating a gap between the placement plate and the connecting frame. Then, an electric telescopic rod drives a push plate to move, allowing the push plate to move within the gap between the multiple support bars, thus discharging the generated slag. This facilitates slag discharge, reduces the difficulty of slag removal, and accelerates the generation of heat in the combustion furnace.

Description

Technical Field

[0001] This utility model belongs to the field of boiler start-up technology, and in particular relates to a rapid steam supply auxiliary device for boiler start-up. Background Technology

[0002] A start-up furnace is a device used to provide heat during the start-up phase of an industrial production facility. Before the facility starts up, it heats the equipment and pipelines to a certain temperature so that they can meet the conditions for normal operation.

[0003] In order to increase heat output and speed up steam supply, some fuel boilers need to clean the fuel ash inside the furnace regularly. Currently, the common method is to open the furnace door and dig it out with a shovel. This method is inconvenient for ash removal and increases the difficulty of ash removal. Therefore, we propose an auxiliary ash removal device for rapid steam supply to solve the shortcomings of existing technology. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for rapid steam supply to a boiler during startup, which facilitates the discharge of ash and slag from the furnace, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A rapid steam supply auxiliary device for a start-up boiler includes a support frame fixedly connected to the bottom of the surface of a combustion furnace. A hydraulic rod is fixedly connected to the bottom of the inner cavity of the support frame. A placement plate is detachably connected to the telescopic end of the hydraulic rod. Multiple support bars are fixedly connected to the top of the placement plate. A connecting frame is fixedly connected to the bottom of the combustion furnace. Insert rods are fixedly connected to the four corners of the top of the placement plate. Insert holes for sliding insertion of the insert rods are opened at the bottom of the connecting frame and at the corresponding positions. A connecting plate is fixedly connected to the rear side of the connecting frame. An electric telescopic rod is fixedly connected to one side of the connecting plate. A push plate is fixedly connected to the telescopic end of the electric telescopic rod. The initial position of the push plate is located at the rear side of the support frame.

[0006] Preferably, connecting blocks are fixedly connected to both sides of the placement plate, and a guide block is detachably connected to the side of the connecting block away from the placement plate.

[0007] Preferably, guide grooves are provided on both sides of the inner cavity of the support frame, and the inner surface of the guide groove is slidably connected to the outer surface of the guide block.

[0008] Preferably, the bottom of the combustion furnace surface is embedded and fixedly connected to the top of the inner cavity of the support frame, and the front and rear positions of the support frame are open structures.

[0009] Preferably, a guide rod is slidably connected to the inner surface of the connecting plate, and the guide rod is fixedly connected to the push plate.

[0010] Preferably, the push plate has a rake-shaped design, and the push plate and the support bar are staggered.

[0011] The beneficial effects of this utility model are:

[0012] 1. When slag needs to be cleaned, this utility model only requires the hydraulic rod to drive the placement plate downward, and the insertion rod to slide and guide it on the inner surface of the insertion hole, so that a gap is created between the placement plate and the connecting frame. Then, the electric telescopic rod drives the push plate to move, so that the push plate moves within the gap between multiple support bars, thereby discharging the generated slag. This facilitates the discharge of slag, reduces the difficulty of slag discharge, and accelerates the generation of heat in the combustion furnace.

[0013] 2. This utility model facilitates the disassembly and replacement of the placement plate by setting a detachable connection between the connecting block and the guide block. At the same time, the guide block slides in the guide groove to guide the up and down movement of the placement plate.

[0014] 3. This utility model guides the movement of the push plate by setting a guide rod that slides through the inner surface of the connecting plate;

[0015] 4. This utility model features a rake-shaped push plate with staggered arrangement between the push plate and the support bars. This allows for the cleaning of ash and slag within the gaps between the support bars, while the movement of the push plate also facilitates the pushing of ash and slag. Attached Figure Description

A hydraulic rod 3 is fixedly connected to the bottom of the inner cavity of the support frame 2. A placement plate 4 is detachably connected to the telescopic end of the hydraulic rod 3. Connecting blocks 13 are fixedly connected to both sides of the placement plate 4. A guide block 14 is detachably connected to the side of the connecting block 13 away from the placement plate 4. Guide grooves 15 are provided on both sides of the inner cavity of the support frame 2. The inner surface of the guide groove 15 is slidably connected to the outer surface of the guide block 14. The detachable connection between the connecting blocks 13 and the guide blocks 14 facilitates the disassembly and replacement of the placement plate 4. At the same time, the guide block 14 slides in the guide groove 15 to guide the up and down movement of the placement plate 4. Multiple support bars 5 are fixedly connected to the top of the placement plate 4. A connecting frame 6 is fixedly connected to the bottom of the combustion furnace 1. Insert rods 7 are fixedly connected to the four corners of the top of the placement plate 4. Insert holes 8 are provided at the bottom of the connecting frame 6 and corresponding to the insert rods 7, for sliding insertion into the insert rods 7. A connecting plate 10 is fixedly connected to the rear side of the connecting frame 6. A guide rod 9 is slidably connected to the inner surface of the connecting plate 10. The guide rod 9 is fixedly connected to the push plate 12. By setting the guide rod 9 to slide on the inner surface of the connecting plate 10, the movement of the push plate 12 is guided. An electric telescopic rod 11 is fixedly connected to one side of the connecting plate 10. The telescopic end of the electric telescopic rod 11 is fixedly connected to the push plate 12. The initial position of the push plate 12 is located at the rear side of the support frame 2. When it is necessary to clean the slag, the hydraulic rod 3 drives the placement plate 4 to move downward, and the insertion rod 7 slides on the inner surface of the insertion hole 8 to guide it. After a gap is created between the placement plate 4 and the connecting frame 6, the electric telescopic rod 11 drives the push plate 12 to move. This allows the push plate 12 to move within the gap between multiple support bars 5, thereby discharging the generated slag. This facilitates the discharge of slag, reduces the difficulty of slag discharge, and the timely cleaning of slag accelerates the generation of heat in the combustion furnace 1.

[0026] Example 2:

The bottom of the surface of the combustion furnace 1 is embedded and fixedly connected to the top of the inner cavity of the support frame 2. The front and rear positions of the support frame 2 are open. A hydraulic rod 3 is fixedly connected to the bottom of the inner cavity of the support frame 2. A placement plate 4 is detachably connected to the telescopic end of the hydraulic rod 3. Multiple support bars 5 are fixedly connected to the top of the placement plate 4. A connecting frame 6 is fixedly connected to the bottom of the combustion furnace 1. Insert rods 7 are fixedly connected to the four corners of the top of the placement plate 4. The bottom of the connecting frame 6 and the corresponding insertion rods 7 are... An insertion hole 8 is provided at the insertion point for sliding insertion of the insertion rod 7.

A push plate 12 is fixedly connected to the telescopic end of the electric telescopic rod 11. The push plate 12 has a rake-shaped design and is staggered with the support bar 5. By setting the push plate 12 to a rake-shaped design and staggering it with the support bar 5, the ash and slag in the gap between the support bars 5 are cleaned. At the same time, the movement of the push plate 12 also facilitates the pushing of ash and slag. The initial position of the push plate 12 is located at the rear side of the support frame 2.

[0028] Working principle: When this utility model is used, the fuel inside the combustion furnace 1 is burned and heat is generated by the existing technology of the combustion furnace 1. When it is necessary to clean the slag, the hydraulic rod 3 drives the placement plate 4 to move downward, and the insertion rod 7 slides and guides it on the inner surface of the insertion hole 8. At the same time, the guide block 14 slides in the guide groove 15 to guide the up and down movement of the placement plate 4. After a gap is created between the placement plate 4 and the connecting frame 6, the electric telescopic rod 11 drives the push plate 12 to move. This allows the push plate 12 to move within the gap between the multiple support bars 5. At the same time, the movement of the push plate 12 also facilitates the pushing of ash and slag, thereby discharging the generated slag. This facilitates the discharge of slag, reduces the difficulty of slag discharge, and accelerates the generation of heat inside the combustion furnace 1.
