Description

Technical Field

[0001] The utility model relates to the technical field of dust cleaning devices for heat storage chambers, in particular to a dust cleaning device for heat storage chambers. Background Art

[0002] The regenerator is actually a waste heat recovery device, which is part of the exhaust gas waste heat utilization system. It uses refractory materials as heat storage bodies (called checker bricks) to store part of the heat of the flue gas discharged from the kiln to heat the air entering the kiln.

[0003] In the middle and late stages of the float kiln, as the raw material ash enters the regenerator and the checker bricks in the regenerator peel off, a large amount of ash is deposited at the bottom of the regenerator, which blocks the passage of flue gas and combustion-supporting air. In the traditional way, the kiln maintenance personnel are arranged to enter the interior through the ash removal door to clean up. When there is a lot of ash accumulation, it is necessary to use an ash removal shovel to clean outwards. The ash removal shovel is connected to a rope, and several people pull the rope outside to discharge the accumulated ash from the regenerator. Because the ash is agglomerated and heavy, it is very difficult to pull the rope manually, and the manpower has poor sustainability and low efficiency.

[0004] The utility model patent with the authorization announcement number CN206654837U provides a kiln for glass substrate production, which mentions a dust suction device for industrial kilns. The dust suction device includes a dust suction pipe having a dust suction pipe opening and a dust outlet pipe opening. The pipe wall of the dust suction pipe is bypassed by a compressed air intake branch pipe. The compressed air blown out of the compressed air intake branch pipe is blown toward the dust outlet pipe opening to form a negative pressure area at the dust suction pipe opening. The dust suction device also includes a first cooling structure for cooling the dust suction pipe. In this way, compressed air is blown toward the dust outlet pipe opening through the compressed air intake branch pipe to form a negative pressure area at the dust suction pipe opening of the dust suction pipe, thereby sucking out the high-temperature accumulated dust in the industrial kiln.

[0005] However, this dust collecting device can only be used to remove dust accumulation that is light in weight and small in volume, and cannot be used for dust accumulation that is agglomerated. Based on this, the prior art still needs to be improved. Utility Model Content

The dust scraping shovel is arranged inside the heat storage chamber. The traction device is arranged outside the heat storage chamber, and the traction device is connected to the dust scraping shovel through a traction rope and tractions the dust scraping shovel to move toward the heat storage chamber.

[0008] In some embodiments, the traction device includes a winch, and the traction rope is a steel wire rope on the winch, and the steel wire rope is connected to the ash scraping shovel. The winch pulls the ash scraping shovel toward the ash scraping door of the heat storage chamber by winding the steel wire rope.

[0009] In some embodiments, the winch is fixed at a preset position by a fixing mechanism to ensure that the winch has sufficient stability to prevent sliding or overturning during operation.

[0010] In some embodiments, the heat storage chamber dust removal device further includes a fixed pulley system, wherein the fixed pulley of the fixed pulley system is rotatably arranged on a target wall through a support assembly, and the target wall is located in front of the dust removal door of the heat storage chamber; the steel wire rope of the winch passes around the fixed pulley and is connected to the dust removal shovel. Through the above connection method, the direction of force can be changed and the load can be distributed, allowing the operator to apply force to the dust removal shovel at a more appropriate angle or direction. It can also help reduce the friction between the steel wire rope and other components, making the operation more labor-saving and extending the service life of the steel wire rope, thereby improving the working efficiency of the entire system.

[0011] In some embodiments, there are multiple support assemblies, which are arranged in sequence and spaced apart along the first direction on the side of the target wall facing the heat storage chamber, and the position and number of each support assembly correspond to the position and number of checker bricks in the heat storage chamber.

[0012] In some embodiments, the support assembly includes an expansion bolt, the head of the expansion bolt is inserted into the target wall, a pull ring is provided at the end of the expansion bolt, and the pulley bracket of the fixed pulley system is detachably connected to the pull ring, which facilitates the rapid installation and disassembly of the fixed pulley and the replacement of the fixed pulley position according to the cleaning of dust accumulation in different heat storage chambers.

[0013] In some embodiments, the ash shovel includes a shovel head and a shovel handle. The shovel head is provided with a stop surface, and the bottom of the stop surface is a plane. The shovel handle is connected to the shovel head and is set at a preset angle to the stop surface so that the stop surface can fully contact the accumulated ash. The shovel handle is connected to the wire rope on the winch, and the shovel handle always maintains a preset angle with the stop surface when it moves under the tension of the wire rope.

[0014] In some embodiments, a first hook is provided on the shovel handle; and a second hook hooked with the first hook is provided at the end of the wire rope, so as to facilitate quick connection between the shovel handle and the wire rope without unhooking.

[0015] In some embodiments, the winch is located below the fixed pulley system, so that the movable pulley can share part of the weight, thereby reducing the pulling force that the winch 3 needs to provide.

[0016] In some embodiments, the preset angle between the stop surface and the shovel handle does not exceed 90°, which improves the comfort of use, ensures the strength of the device, and reduces operating resistance.

[0017] The utility model has the following beneficial effects: the utility model is provided with an ash scraper and a traction device, and when the accumulated ash in the heat storage chamber is cleaned outward, the traction device is used to automatically pull the ash scraper to move toward the ash scraping opening of the heat storage chamber to remove the accumulated ash. The coordinated use of the traction device and the ash scraper can replace manual operation, reduce labor input, improve work efficiency, and improve operation safety. Moreover, the ash scraper can be used to clean accumulated ash in different forms, and there is no need to break the accumulated ash in blocks into small particles, which saves cleaning time and has a wide range of applications.

[0027] In some embodiments, the winch 3 is fixed at a preset position by a fixing mechanism to ensure that the winch 3 has sufficient stability to prevent sliding or overturning during operation. Specifically, different fixing methods such as bolt anchoring, horizontal anchoring, pile anchoring, and weight anchoring can be selected to fix the winch 3 according to the force applied to the winch 3 and site conditions to adapt to different working environments and requirements.

[0028] In some embodiments, the heat storage chamber dust removal device further includes a fixed pulley system 7, the fixed pulley of the fixed pulley system 7 is rotatably set on the target wall 5 through the support assembly 6, and the target wall 5 is located in front of the dust removal door of the heat storage chamber 1; the wire rope 4 of the winch 3 bypasses the fixed pulley and is connected to the dust removal shovel 8. Through the above connection method, the direction of force can be changed and the load can be distributed, allowing the operator to apply force to the dust removal shovel 8 at a more appropriate angle or direction. It can also help reduce the friction between the wire rope 4 and other components, making the operation more labor-saving and extending the service life of the wire rope 4, thereby improving the working efficiency of the entire system. In particular, the target wall 5 preferably selects the existing concrete wall in front of the heat storage chamber 1. If there is no such wall around the heat storage chamber 1, a target wall 5 can be built at a suitable location.

[0029] In some embodiments, there are multiple support assemblies 6, which are arranged at intervals in sequence along the first direction on the side of the target wall 5 facing the heat storage chamber 1, and the position and number of each support assembly 6 correspond to the position and number of the checker bricks 2 of the heat storage chamber 1. As shown in the figure, the heat storage chamber 1 of this embodiment is sequentially provided with five support assemblies 6 from bottom to top, and five support assemblies 6 are also provided. Each support assembly 6 is located directly in front of the dust removal door of a heat storage chamber 1, so that the hoist 3 can pull the dust removal shovel 8 to move in the horizontal direction through the wire rope 4, so that the bottom of the dust removal shovel 8 keeps in contact with the bottom wall of the heat storage chamber 1, and the accumulated dust is removed at one time.

[0030] In some embodiments, the support assembly 6 includes an expansion bolt, the head of which is inserted into the target wall 5 and has sufficient strength. A pull ring is provided at the end of the expansion bolt, and the pulley bracket of the fixed pulley system 7 is detachably connected to the pull ring.

The shovel handle is connected to the shovel head and is set at a preset angle with the stop surface, so that the stop surface can fully contact the accumulated ash. The shovel handle is connected to the steel wire rope 4 on the winch 3. When the shovel handle moves under the tension of the steel wire rope 4, it always maintains a preset angle with the stop surface, so that the ash scraping shovel 8 has enough ability to take the accumulated ash in front of it out of the heat storage chamber 1 when moving.

[0032] In some embodiments, a first hook is provided on the shovel handle; and a second hook hooked with the first hook is provided at the end of the steel wire rope 4, so as to facilitate quick connection between the shovel handle and the steel wire rope 4 without unhooking.
