[0002] The CDQ waste heat furnace is an important equipment in the coking industry. It is used to achieve efficient utilization of the physical sensible heat of high-temperature coke. Its working principle mainly relies on the heat exchange between cold inert gas (such as exhaust gas after combustion) and red-hot coke in the CDQ furnace, thereby cooling the coke and recovering heat.
[0003] In the process of implementing the solution, the inventors found that the following problems in the prior art have not been well solved: the air outlet is an important part of the dry coke quenching waste heat furnace, and its ash accumulation is closely related to the operating status of the entire system. In actual operation, if the furnace temperature is too low or the combustion is incomplete, ash may accumulate at the air outlet. In addition, if the system is not cleaned and maintained in time, the ash accumulation at the air outlet may also be aggravated. The ash accumulation at the air outlet will not only affect the normal operation of the system and reduce the heat exchange efficiency, but may also cause corrosion and damage to the pipeline, further shortening the service life of the equipment. The traditional method of cleaning requires stopping the furnace, affecting the production rhythm and being labor-intensive and time-consuming. Utility Model Content

DETAILED DESCRIPTION
[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0024] like Figure 1-4 As shown, the dust treatment device for the dry quenching waste heat boiler comprises a furnace body 1, an air outlet pipe 2 is arranged at one end of the furnace body 1, a cleaning mechanism 3 is arranged at the lower side of the air outlet pipe 2 away from the furnace body 1, a collecting mechanism 4 is arranged at the other lower side of the air outlet pipe 2 away from the furnace body 1, a concave groove 21 is cut on the side wall of the air outlet pipe 2 at the position of the cleaning mechanism 3, and a side groove 22 is cut on the side wall of the air outlet pipe 2 at the position of the collecting mechanism 4;
[0025] The cleaning mechanism 3 includes a processing box 31, a block 33 of matching size is arranged inside the processing box 31, a convex plate 32 is fixed to the end of the block 33, and a U-shaped handle 34 is arranged at one end of the processing box 31 away from the convex plate 32. The U-shaped handle 34 penetrates the processing box 31 and is slidably connected. The U-shaped handle 34 passes through one end of the processing box 31 and is fixedly connected to the end of the block 33 away from the convex plate 32;
[0026] The collecting mechanism 4 includes a collecting frame 41, a rear plate 42 is provided at one end of the collecting frame 41 away from the air outlet duct 2, a top groove 43 is opened above one end of the collecting frame 41 close to the side groove 22, a baffle 44 of matching size is inserted through the inside of the top groove 43, and the top of the baffle 44 extends to the outside of the top groove 43.
[0027] Specifically, the convex plate 32 is embedded in the concave groove 21 of a size matching the concave groove 21 to block the concave groove 21 .
[0028] Specifically, one end of the baffle 44 passes through the top groove 43 and is inserted into the interior of the collection frame 41 , and the outer dimension of one end of the baffle 44 inserted into the collection frame 41 is larger than the inner dimension of the side groove 22 , thereby blocking the side groove 22 .
[0029] Specifically, both ends of the U-shaped handle 34 close to the outer wall of the processing box 31 are provided with external screw teeth 35, and the external screw teeth 35 are threadedly connected with an adjusting nut 36, so that the convex plate 32 can be stably located in the concave groove 21.
[0030] Specifically, baffle rods 37 are fixed at both ends of the top of the U-shaped handle 34 away from the processing box 31. The distance between the baffle rod 37 and the processing box 31 matches the distance between the two ends of the block 33. The distance between the two ends of the block 33 is larger than the distance between the concave groove 21 and the side groove 22. The baffle rod 37 facilitates observation of the moving distance of the block 33. When the baffle rod 37 is close to or in contact with the outer wall of the processing box 31, it means that the distance moved by the block 33 has pushed the dust into the collection frame 41.
[0031] Specifically, fixing rods 46 are fixed at both ends of the outer top of the collecting frame 41 near the baffle 44, and a hanging plate 45 is fixed to the side wall of the baffle 44 located at the outer top of the collecting frame 41. The hanging plate 45 and the fixing rod 46 are penetrated and slidably connected, and a stopper 410 is fixed on the top of the fixing rod 46 to prevent the baffle 44 from moving excessively.
[0032] Specifically, the fixing rod 46 is provided with an external threaded tooth 47 at the outer wall above the hanging plate 45, and the fixing rod 46 is threadedly connected with an adjusting nut 48 through the external threaded tooth 47. The bottom of the adjusting nut 48 is in contact with the top of the hanging plate 45, so that the baffle 44 can be stably restricted in the collection frame 41, so that it can stably block the side groove 22.
[0033] Specifically, bolts 49 are inserted into the four corners of the rear plate 42 , and the bolts 49 pass through one end of the rear plate 42 and are respectively threadedly connected to the collecting frame 41 , so that the collecting frame 41 and the rear plate 42 are detachable.
[0034] Working principle:
[0035] The U-shaped handle 34 drives the blocking block 33 to push the convex plate 32, so that it moves from the position of the inner groove 22 of the concave groove 21, and pushes the dust accumulated at the bottom end of the air outlet pipe 2 into the collection frame 41. Before pushing, the baffle plate 44 needs to be pulled up from the collection frame 41, and its bottom needs to be above the horizontal line of the top of the side groove 22. After the convex plate 32 pushes the dust accumulated into the collection frame 41, the U-shaped handle 34 drives the blocking block 33 and the convex plate 32 to move back to the origin, and moves to the position of the outer screw tooth 35 by adjusting the nut 36 and is threadedly connected with it, so that the convex plate 32 can be stably located in the concave groove 21 to avoid movement;
[0036] When the accumulated dust is located in the collecting frame 41, the baffle 44 is lowered and inserted into the collecting frame 41 to seal the side groove 22. The adjusting nut 48 is lowered to the outer thread 47 and rotated to press the hanging plate 45 and keep the baffle 44 stable when sealing the side groove 22. Then the bolts 49 are removed and the rear plate 42 is taken off. At this time, the end of the collecting frame 41 is in an open state, and the dust inside it can be taken out.
[0037] The circuits, electronic components and control modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to software and methods.
[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
