Description

Technical Field

[0001] This utility model relates to the field of economizer ash hopper technology, and in particular to an economizer ash hopper anti-clogging device. Background Technology

[0002] The economizer ash hopper is an important component of the boiler system. It is usually installed below the economizer and is used to collect and discharge the ash and sediment generated during the operation of the economizer. The economizer is a heat exchange device that uses the waste heat of the flue gas at the tail end of the boiler to heat the feedwater. By increasing the feedwater temperature and reducing the flue gas temperature, the thermal efficiency of the boiler is improved. However, as the flue gas passes through the economizer, it carries a certain amount of ash and particulate matter. These substances are deposited on the surface of the economizer and form ash, which needs to be collected and discharged through the ash hopper.

[0003] The ash hopper body is usually conical or square in shape to facilitate the collection and concentration of ash and slag. The ash discharge port is located at the bottom of the ash hopper and is used to connect the ash discharge pipe or equipment to discharge the ash and slag from the system. Economizer ash discharge has the characteristics of coarse particles, high specific gravity, high temperature, high viscosity and high air permeability.

[0004] The accumulation and blockage of ash in the ash hopper usually leads to boiler downtime, affecting the continuous and stable operation of the boiler. It also results in insufficient ash discharge from the ash hopper, making it impossible to achieve continuous and stable ash discharge, thus reducing the overall operating efficiency of the boiler. Therefore, an anti-blockage device for ash discharge in the economizer ash hopper is proposed to solve the above problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model designs an economizer ash hopper anti-clogging device, which has the advantages of improving the overall operating efficiency of the boiler. It solves the problem that the boiler shutdown caused by the accumulation and blockage of ash in the ash hopper usually affects the continuous and stable operation of the boiler. At the same time, it also leads to insufficient ash discharge from the ash hopper, which cannot achieve continuous and stable ash discharge and reduces the overall operating efficiency of the boiler.

[0006] The present invention adopts the following technical solution:

[0007] An economizer ash hopper anti-clogging device includes an ash hopper body, an anti-clogging structure installed inside the ash hopper body, and a discharge structure installed outside the ash hopper body. The anti-clogging structure includes an inclined plate, which is fixedly installed inside the ash hopper body. The lower end of the inclined plate is positioned corresponding to the discharge structure. Partitions are installed at intervals on the inclined plate, forming a material discharge trough between the partitions. A rotating shaft is rotatably connected inside the ash hopper body below the inclined plate. A motor is fixedly connected to one end of the rotating shaft, and fan blades are fixedly connected to the rotating shaft, with the fan blades positioned corresponding to the material discharge trough.

[0008] Preferably, the discharge structure includes a discharge pipe, and a baffle is movably installed inside the discharge pipe. The baffle is controlled to open and close by a power device to realize the opening and closing of the discharge pipe.

[0009] Preferably, a limiting rod is fixedly installed on the outside of the baffle, a fixing plate is fixedly installed on the outside of the discharge pipe, a screw is rotatably installed inside the fixing plate, an extension plate is fixedly installed at the bottom of the fixing plate, a connecting shaft is rotatably installed inside the extension plate, a gear is fixedly installed on the outside of the connecting shaft, a swing rod is hinged to the outside of the connecting shaft, a slide rail is provided on the swing rod, the limiting rod passes through the slide rail and is slidably connected to the slide rail, and the screw meshes with the gear.

[0010] Preferably, the motor is fixedly installed on the outside of the ash hopper body, and the output shaft of the motor passes through the ash hopper body and is fixedly connected to the rotating shaft.

[0011] Preferably, a bearing is installed at the connection between the rotating shaft and the ash hopper body.

[0012] Preferably, multiple partitions are evenly spaced on the inclined plate, forming multiple material discharge slots between the partitions, and multiple fan blades are fixedly connected to the rotating shaft, with the fan blades passing through the material discharge slots.

[0013] Preferably, the connecting shaft passes through the extension plate and is rotatably connected to the extension plate.

[0014] Preferably, the top of the baffle passes through the discharge pipe and is movably connected to the discharge pipe, and the limiting rod passes through the discharge pipe and extends to the outside of the discharge pipe.

[0015] The beneficial effects of this utility model are: When it is necessary to clean up the debris in the ash hopper of this economizer, the screw is rotated, and the swing rod swings through the rotation of the gear, thereby driving the limit rod and the baffle to move. When the baffle moves up, the channel of the discharge pipe will be opened, which facilitates the cleaning of debris and reduces the boiler shutdown problem caused by the blockage of the ash hopper body.

[0022] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0023] Example: Figures 1-5 As shown, an economizer ash hopper anti-clogging device includes an ash hopper body 1, an anti-clogging structure 2 installed inside the ash hopper body 1, and a discharge structure 3 installed outside the ash hopper body 1.

[0024] The anti-clogging structure 2 includes an inclined plate 201, which is fixedly installed inside the ash hopper body 1. A partition 202 is fixedly installed inside the inclined plate 201. A rotating shaft 203 is installed for the rotation of the ash hopper body 1. A fan blade 204 is fixedly installed outside the rotating shaft 203. A motor 205 is fixedly installed outside the ash hopper body 1.

[0025] The discharge structure 3 includes a discharge pipe 301. The discharge pipe 301 is fixedly installed on the outside of the ash hopper body 1. A baffle 302 is movably installed inside the discharge pipe 301. A limit rod 303 is fixedly installed on the outside of the baffle 302. A fixing plate 304 is fixedly installed on the outside of the discharge pipe 301. A screw 305 is rotatably installed inside the fixing plate 304. An extension plate 306 is fixedly installed at the bottom of the fixing plate 304. A connecting shaft 307 is rotatably installed inside the extension plate 306. A gear 308 is fixedly installed on the outside of the connecting shaft 307. A swing rod 309 is fixedly installed on the outside of the connecting shaft 307.

[0026] exist Figure 2 In the middle, there is a gap between every two partitions 202. When the motor 205 drives the rotating shaft 203 to rotate, the fan blade 204 will move just inside the gap, so that the particles stuck in the gap can be cleared and the inclined plate 201 can be prevented from being blocked.

[0027] exist Figure 5 In the middle, gear 308 is fixedly connected to connecting shaft 307. When gear 308 rotates, connecting shaft 307 will also rotate synchronously, which drives swing rod 309, causing swing rod 309 to swing and drive baffle 302 to move.

[0028] exist Figure 4In the process, the baffle 302 will fit against the inner wall of the discharge pipe 301 inside the discharge pipe 301, while the limiting rod 303 passes through the discharge pipe 301 and is movably connected to the discharge pipe 301. The limiting rod 303 can effectively prevent the baffle 302 from separating from the discharge pipe 301.

[0029] During implementation, the following steps are performed: When in use, after the ash and slag enter the ash hopper body 1, the impurities in the ash and slag are filtered by the baffle 202 inside the inclined plate 201, so that the impurities will move along the inclination of the inclined plate 201 into the discharge pipe 301. The motor 205 is turned on to prevent the impurities from getting stuck between the two baffles 202. When it is necessary to clean the impurities, the screw 305 is turned, and the channel of the discharge pipe 301 will be opened to facilitate the cleaning of the impurities and reduce the boiler shutdown problem caused by the blockage of the ash hopper body 1.

[0030] In summary, the economizer ash hopper anti-clogging device, when ash and slag enter the ash hopper body 1, will preferentially fall onto the inclined plate 201. The baffles 202 inside the inclined plate 201 filter out impurities in the ash and slag, causing the impurities to move along the inclination of the inclined plate 201 into the discharge pipe 301. By turning on the motor 205, the rotating shaft 203 rotates, and the fan blades 204 move the impurities, preventing them from getting stuck between the two baffles 202 and causing blockage. When it is necessary to clean the impurities, the screw 305 is rotated, and the gear 3... The rotation of 08 causes the swing rod 309 to swing, thereby driving the limit rod 303 and the baffle 302 to move. When the baffle 302 moves upward, the channel of the discharge pipe 301 will open, which facilitates the cleaning of debris and reduces the boiler shutdown problem caused by the blockage of the ash hopper body 1. It solves the problem that the accumulation and blockage of ash in the ash hopper usually leads to boiler shutdown time due to ash hopper blockage, affecting the continuous and stable operation of the boiler. At the same time, it will also lead to insufficient ash discharge from the ash hopper, making it impossible to achieve continuous and stable ash discharge, thus reducing the overall operating efficiency of the boiler.
