Description

Technical Field

[0001] The utility model mainly relates to the field of tire vulcanization, and in particular to a waste heat boiler dust cleaning and collecting device. Background Art

[0002] Waste heat boilers are usually installed in waste incineration plants for energy recovery, which are used to generate steam for direct use or power generation. Economizers, evaporators, and superheaters are installed inside the boiler for heat exchange between flue gas and desalted water. During operation, dust is easily accumulated on the upper part of these pipes. The accumulated dust contains a certain amount of moisture and has strong adhesion, making it difficult to clean it through the soot blowing system.

[0003] In the invention patent application with application number CN202221509676.X, application publication date 2022.10.21, and name "A pulse-type boiler ash cleaner", it includes a hand-held part, a connecting pipe connected to the hand-held part, and a cleaning head connected to the end of the connecting pipe away from the hand-held part. The connecting pipe includes a plurality of splicing pipes detachably connected to the hand-held part, a boss is provided at one end of the splicing pipe in the length direction, the boss is plug-matched with the splicing pipe, a protrusion is provided on the boss, and a slot for the protrusion to be plugged in is provided at the end of the splicing pipe away from the boss. A limiting unit for limiting the displacement of the protrusion is also provided on the splicing pipe. The device enables multiple splicing pipes to be connected together through the plug-in cooperation of the protrusion and the slot, thereby changing the overall length of the connecting pipe to realize the cleaning of the ash accumulated inside the waste heat boiler; the setting of the limiting unit improves the stability of the connection between two adjacent splicing pipes.

[0004] However, when the boiler ash cleaner is in operation, the surface temperature of the boiler ash is relatively high, which may cause burns during centralized cleaning, and manual cleaning is required during centralized cleaning. Utility Model Content

[0005] 1. Technical problems to be solved by the utility model:

[0006] The utility model provides a waste heat boiler ash cleaning and collection device, which is used to solve the problem that the surface temperature of the boiler ash is high, which leads to easy scalding during centralized cleaning, and the problem that manual cleaning is required during centralized cleaning.

[0007] 2. Technical solution:

[0008] To achieve the above-mentioned purpose, the technical solution provided by the utility model is: a waste heat boiler dust cleaning and collection device, comprising a collection outer tank body, a dust inlet pipe is fixedly connected to the top surface of the collection outer tank body, a cleaning crank is arranged on one side of the collection outer tank body, a rope reel is arranged on one side of the cleaning crank, a pull rope is arranged on the surface of the rope reel, a guide pipe is arranged on one side of the collection outer tank body, a water injection pipe is arranged on the other side of the collection outer tank body, and a dust cleaning device is arranged inside the collection outer tank body.

[0009] The dust cleaning device includes an ash bin, sliding grooves are provided on both side surfaces of the ash bin, return springs are provided on the surface of the sliding grooves, a translation plate is provided on one side surface of the return spring, a translation brush is provided on the lower surface of the translation plate, an ash plate is provided under the ash bin, a falling collection hole is provided on the surface of the ash plate, a discharge valve is provided on the side of the collecting outer tank body close to the guide pipe, and a water tank is provided under the ash plate.

[0010] Furthermore, one end of the pull rope is fixed to the surface of the rope reel, and is in turn fixedly connected to the surface of the translation plate through a guide tube.

[0011] Furthermore, the translation brush and the translation plate form a sliding structure on the surface of the sliding groove, and an elastic reset structure is formed on the surface of the sliding groove through a reset spring.

[0012] Furthermore, the translation brush and the translation plate form a moving structure on the surface of the dust removal plate by winding the pull rope through the rope winding wheel.

[0013] Furthermore, the water injection pipe is interconnected with the water reservoir, and the water reservoir is discharged through a discharge valve.

[0014] 3. Beneficial effects:

[0015] The utility model has a reasonable design. When the ash accumulated in the waste heat boiler is cleaned, the ash accumulated in the waste heat boiler first enters the interior of the collection tank through the ash inlet pipe. At the same time, the cleaning crank is driven to rotate the rope reel by shaking the cleaning crank, and then the pull rope is wound around the surface of the rope reel. The pull rope is reversed through the roller on the surface of the guide tube to move the translation plate in the dust cleaning device inside the collection tank toward the guide tube. At the same time, the translation brush under the translation plate is used to sweep the ash accumulated on the surface of the ash falling plate under the action of the translation plate, and the ash accumulated in the ash falling plate is dropped into the water storage tank through the collection hole on the surface of the ash falling plate. At this time, cooling water is input into the water storage tank through the water injection pipe. The cooling water inside the water storage tank, on the one hand, avoids the ash accumulated floating in the air due to cleaning, and on the other hand, the cooling water is used to cool the boiler ash accumulated, so as to avoid accidents caused by excessive temperature. The discharge valve is opened to notify the continuous injection of water into the water storage tank through the water injection pipe, so that the ash accumulated in the cooling water is discharged from the water storage tank, thereby avoiding the purpose of manual discharging.
