Description

Technical Field

[0001] The utility model relates to the technical field of slag dischargers, and more specifically to a slag discharger for a steam boiler. Background Art

[0002] A steam boiler refers to a boiler device for producing steam, which is widely used in daily life, such as: steaming rice, steaming buns, cooking, sauna, disinfection, beauty, etc. In production, such as chemical heating, dyeing, pharmaceutical, building materials production, food production, etc., steam boilers mostly use coal as fuel. After the coal burns, coal cinder will remain. To avoid the coal cinder affecting the normal operation inside the steam boiler, the coal cinder needs to be discharged from the boiler. With the progress of technology, a slag discharger is used to replace the traditional manual method for slag discharging. A slag discharger is a boiler slag discharging device. The cinder produced after the coal burns in the boiler is pushed by the grate to the slag storage pit, and is dragged out of the furnace by the slag discharger to dredge the accumulation of slag.

[0003] Deficiencies of the prior art: When the coal cinder is discharged from the boiler, its temperature is relatively high. When the existing slag dischargers are in use, they mostly directly discharge the coal cinder. The residual heat on the coal cinder diffuses into the air, causing waste. At the same time, the structure of the coal cinder is loose, and a large amount of dust will be generated when the coal cinder is discharged from the equipment, which diffuses into the air and causes pollution. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a slag discharger for a steam boiler to solve the problems existing in the above background art.

The side inner wall of the device main body is fixedly connected to the side of the cooling mechanism, the top end of the dust reduction mechanism is fixedly connected to the bottom end of the device main body. The device main body includes a machine shell, the top end of the machine shell is connected with a feed hopper, the bottom end of the machine shell is fixedly connected with a discharge hopper, the side of the machine shell is fixedly connected with a mounting block, the top end of the mounting block is fixedly connected with a servo motor, the output shaft of the servo motor is fixedly connected with a mounting shaft, a spiral conveyor paddle is fixedly sleeved on the side of the mounting shaft, the side inner wall of the machine shell is fixedly connected with a heat conducting layer, the cooling mechanism includes a second heat exchange pipe, the side of the second heat exchange pipe is fixedly connected to the side of the heat conducting layer, and the bottom end of the second heat exchange pipe is fixedly connected with a first connecting pipe.

The side of the second heat exchange pipe 204 is fixedly connected to the side of the heat conduction layer 107. The bottom end of the second heat exchange pipe 204 is fixedly connected to a first connecting pipe 203. The top of the feed hopper 103 is aligned with the slag discharge position of the steam boiler. The coal slag falls into the interior of the casing 101 through the feed hopper 103. The servo motor 102 is started to drive the mounting shaft 105 to rotate, so that the spiral conveyor paddle 109 conveys the coal slag and finally discharges it from the discharge hopper 104. Circulating water is introduced through the first connecting pipes 203 on both sides of the second heat exchange pipe 204. The circulating water enters the interior of the second heat exchange pipe 204 through the first connecting pipe 203, contacts the coal slag, takes away the heat in the coal slag for reuse, and cools the coal slag.

[0022] Among them, the second heat exchange pipe 204 is of a spiral structure, and the casing 101 is made of heat-insulating material.

[0023] Among them, a first heat exchange tube 202 is fixedly connected inside the installation shaft 105. A sealing sleeve 201 is movably sleeved on the side surface of the installation shaft 105. A second connecting pipe 205 is fixedly connected to the side surface of the sealing sleeve 201. The first heat exchange tubes 202 are evenly distributed inside the installation shaft 105 and the screw conveyor paddle 109 to ensure uniform contact with the cinder. During use, the circulating water enters the inside of the first heat exchange tube 202 through the second connecting pipe 205 and the sealing sleeve 201. When the installation shaft 105 rotates, it rotates along the inner wall of the side surface of the sealing sleeve 201. The sealing sleeve 201 allows the circulating water to enter the inside of the first heat exchange tube 202 to cool the cinder.

[0024] Among them, a crushing roller 106 is fixedly connected to the side surface of the installation shaft 105 corresponding to the position of the feed hopper 103. The installation shaft 105 drives the crushing roller 106 to rotate, so that the crushing roller 106 crushes the cinder falling into the machine shell 101 into smaller pieces, which is convenient for transportation.

[0025] Among them, the dust reduction mechanism 3 includes a water tank 301. A threaded cover 304 is threadedly connected to the top end of the water tank 301.

A water outlet pipe 302 is fixedly connected to the side surface of the conduit 306. A spray nozzle is fixedly connected to the inner wall of the side surface of the water outlet pipe 302. The top end of the water outlet pipe 302 is fixedly connected to the bottom end of the discharge hopper 104. Open the threaded cover 304 to inject sufficient water into the water tank 301. The water pump 305 operates to pump the water inside the water tank 301 out, transports it to the water outlet pipe 302 through the conduit 306, and sprays it through the spray nozzle to reduce the dust of the cinder and prevent the dust from spreading into the air.

[0026] Among them, an observation pipe 303 is fixedly connected to the side surface of the water tank 301. A scale is provided on the side surface of the observation pipe 303. The water storage inside the water tank 301 is determined through the observation pipe 303 made of transparent material.

[0027] Working principle of the utility model: Open the threaded cap 304 and inject sufficient water into the water tank 301. Align the top of the feed hopper 103 with the slag discharge position of the steam boiler. The coal slag falls into the interior of the casing 101 through the feed hopper 103. Start the servo motor 102 to drive the installation shaft 105 to rotate. The crushing roller 106 crushes the coal slag falling into the casing 101. Then, the coal slag is conveyed by the spiral conveyor paddle 109 and finally discharged from the discharge hopper 104. At the same time, circulating water is connected through the first connecting pipe 203 on both sides of the second heat exchange pipe 204. The circulating water enters the interior of the second heat exchange pipe 204 through the first connecting pipe 203. The circulating water enters the interior of the first heat exchange pipe 202 through the second connecting pipe 205 and the sealing sleeve 201. When the installation shaft 105 rotates, it rotates along the inner wall of the side surface of the sealing sleeve 201. The sealing sleeve 201 allows the circulating water to enter the interior of the first heat exchange pipe 202, come into contact with the coal slag, take away the heat in the coal slag for reuse, and cool the coal slag. When the coal slag is discharged from the discharge hopper 104, the water pump 305 operates to pump out the water in the water tank 301, convey it through the conduit 306 to the water outlet pipe 302, and spray it through the atomizing nozzle to dust the coal slag, avoiding the dust from spreading into the air.
