Description

Technical Field

[0001] This utility model relates to the field of boiler slag discharge technology, specifically a boiler slag discharge mechanism with large dust prevention capabilities. Background Technology

[0002] In industrial production, boilers are widely used as important energy conversion equipment. The slag produced during boiler operation needs to be discharged in a timely manner to ensure the normal operation of the boiler.

[0003] Currently, traditional boiler ash removal mechanisms generally have some problems. During ash removal, the falling ash generates a large amount of dust, which is scattered into the working environment. On the one hand, this seriously affects the air quality in the workplace and endangers the health of operators. Long-term exposure to such an environment makes operators highly susceptible to occupational diseases such as respiratory diseases. On the other hand, the large amount of dust emissions does not meet the current strict environmental protection requirements.

[0004] Meanwhile, the traditional slag discharge pipe lacks an effective cleaning device, and slag easily adheres and accumulates on the inner wall of the slag discharge pipe. This not only hinders the smooth discharge of slag and reduces the efficiency of slag discharge, but may also cause blockage of the slag discharge pipe, increasing the probability of equipment failure and maintenance costs. Utility Model Content

[0005] The purpose of this utility model is to provide a boiler dust-preventing ash discharge mechanism to solve the problems mentioned in the background art.

[0011] Preferably, the filter element includes a support block, which is slidably disposed at the bottom of the dust collection box. A square through groove is formed at the center of the support block, and a filter screen is laid inside the square through groove.

[0012] Preferably, the driving component includes a motor, which is fixed to the top right side of the dustproof box. A turntable is fixed to the output end of the motor, and the outer wall of the turntable is rotatably connected to the transmission rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By setting up a dustproof box and connecting pipes, the dust generated when slag falls is transported to the dust collection box, effectively preventing dust from overflowing, significantly reducing dust pollution in the working environment, protecting the health of operators, and meeting environmental protection requirements.

[0018] The rotating rod and scraper design in the cleaning component allows the scraper to rotate synchronously when the rotating rod rotates, which can automatically clean the slag adhering to the inner wall of the slag discharge pipe, avoid slag accumulation affecting slag discharge efficiency, and ensure the smooth operation of the slag discharge pipe.

[0019] The protective net inside the dust collector can block dust and prevent it from being discharged by the fan. The cooling components can cool the slag and reduce dust generation. The filter screen in the filter components is made of glass fiber, which has a good filtration effect and can effectively separate dust and water. At the same time, it is convenient to centrally process the filtered dust.

[0020] The motor in the drive unit drives the turntable to rotate, and the eccentrically connected transmission rod achieves stable pushing of the push rod. Then, by utilizing the cooperation of the transmission component and the connecting rod, the rotating rod is precisely driven to rotate. The entire transmission process is stable and reliable, ensuring the continuous operation of the cleaning component. Moreover, the structure is simple and easy to maintain and repair.

When the push rod 18 moves left and right, it drives the connecting rod 20 to swing left and right through the transmission unit 19. The transmission unit 19 is fixed to the outer wall of the push rod 18. The transmission unit 19 has a strip-shaped groove inside, and the connecting rod 20 is movably arranged inside the strip-shaped groove.

[0036] Working Principle: When a boiler dust-prevention slag discharge mechanism is first put into use, the user controls the motor 15 and fan 9 through an external control unit. The output end of the motor 15 rotates, causing the turntable 16 to rotate simultaneously. The turntable 16 drives the push rod 18 to reciprocate through the transmission rod 17 with an eccentric connection on its surface. During the movement, the push rod 18 drives the connecting rod 20 to swing left and right through the transmission component 19. When the connecting rod 20 swings left and right, it drives the edge of the scraper 4 through the rotating rod 3 to clean the slag adhering to the inner wall of the slag discharge pipe 1. The cleaned slag falls downwards through the bottom end of the slag discharge pipe 1 into the inner wall of the dustproof box 5 and then into the slag collection box 6. The dust generated when the slag falls is then removed by the fan 9. The negative pressure generated inside the dust collector 7 is drawn into the dust collector 7 through the connecting pipe 8. After being drawn in, water enters the cooling component 11 through the water pipe above the cooling component 11 and forms atomized water sprayed out, covering the dust to achieve a dust reduction effect. The wet dust falls down with the atomized water onto the surface of the filter screen 13. The filter screen 13 filters the process water through the filter screen 13 and falls to the bottom of the dust collector 7. The wastewater can be discharged and recycled through the drain port 14 at the bottom. The suction generated by the fan 9 during operation draws some dust upwards. The protective net 10 can effectively prevent the dust from being discharged through the connecting pipe 8. After the slag discharge is completed, the slag collected inside the slag collection box 6 can be taken out and cleaned.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
