The top of the spring 65 is fixedly connected with the support rod 8. The top of the support rod 8 passes through the box body 7 and is bolted with the filter screen 61. The bottom of the filter screen 61 is in contact with the top of the eccentric wheel 64; the smoke is filtered to remove dust and impurities in the smoke, avoid dust clogging the gas transmission pipe 4, improve the gas transmission efficiency, and at the same time vibrate the filter screen 61 to avoid clogging of the filter screen 61.

[0026] Reference Figure 4A sealing gasket 9 is bonded to the top of the inner cavity of the box body 7, and the inner side of the sealing gasket 9 contacts the surface of the support rod 8, thereby improving the sealing performance of the box body 7.

[0027] Reference Figure 3 The right side of the filter box 2 is connected to a slag discharge pipe 10, and a pipe cover 11 is clamped on the surface of the slag discharge pipe 10; it is convenient to discharge the impurities filtered on the filter screen 61 out of the filter box 2, reducing the number of times the filter box 2 is cleaned.

[0028] Reference Figure 2 The bottom of the right side of the filter box 2 is bolted with a frame 12, and the frame 12 is located below the slag discharge pipe 10; the dust discharged from the filter box 2 is collected for subsequent processing.

The circulation of high-temperature flue gas heats the water, and then the flue gas is transported to the exhaust pipe 5 and discharged from the box body 1. The heated water is discharged through the water outlet pipe for use. The user turns on the motor 62, and the motor 62 drives the rotating shaft 63 to rotate, so that the rotating shaft 63 drives the eccentric wheel 64 to rotate. Under the action of the spring 65, the eccentric wheel 64 strikes the filter 61 back and forth, causing the filter 61 to vibrate to prevent the filter 61 from being blocked. The dust and impurities fall into the slag discharge pipe 10 along the inclination of the filter 61. When there are too many dust and impurities, open the pipe cover 11 to discharge the dust and impurities into the frame 12 for collection.
