[ detailed description ] embodiments

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be further described with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, the improved rock wool production line tail gas filtering device of the present invention comprises a filtering chamber 1, wherein an air inlet 3 is arranged at the bottom of the side surface of the filtering chamber, an air outlet 4 is arranged at the upper part of the opposite surface of the air inlet 3, the air outlet 4 is connected with an exhaust fan outside the filtering chamber, lower supporting frames 5 are transversely laid at the upper position of the air inlet in the filtering chamber 1 at intervals, an upper supporting frame 6 is transversely laid above between every two adjacent lower supporting frames 5, a filtering plate 7 is vertically arranged between the upper supporting frame 6 and the lower supporting frames 5, and a nozzle 8 is arranged on the lower surface of; be provided with electric contact pressure gauge 9 on the pipeline of air outlet 4, ash collecting chamber 2 of bottom installation of filter chamber 1, ash collecting chamber 2 sets up to the down triangular prism shape, sets up a scraper blade 10 on its two inclined planes respectively, spiral auger 11 is installed along its length direction in ash collecting chamber 2 bottom.

As shown in fig. 2, the scraper 10 is driven by a first motor 101, the first motor 101 is fixedly arranged outside the dust collecting chamber 2, and an output shaft of the first motor passes through a bearing on the side wall of the dust collecting chamber and is fixedly connected with the scraper 10; the spiral auger 11 is driven by a second motor 111, the second motor 111 is fixed outside the dust collection chamber 2, and an output shaft of the second motor penetrates through a bearing on the side wall of the dust collection chamber and is fixedly connected with the spiral auger 11; a water inlet pipe 12 is arranged above the upper support frame 6 in the filter chamber 1, and the nozzle 8 is connected with an external high-pressure water pump through the water inlet pipe 12.
