Be equipped with first gas outlet 4 in dust removal case 1 upper end, first gas outlet 4 and first intake pipe 13 intercommunication are sent into the gas after filtering through first intake pipe 13 and are washed 2 washings in the washing room.

A filter screen plate 5 is arranged in the dust removal box 1, and the filter screen plate 5 divides the interior of the dust removal box 1 into an upper space and a lower space. Four corners of the lower end of the filter screen plate 5 are provided with elastic lifting support legs 6. And the upper end of the filter screen plate 5 is provided with an ash bucket mechanism 7.

As shown in fig. 3, the elastic lifting leg 6 comprises a T-shaped rod 6-1, and the T-shaped rod 6-1 freely passes through a fixed block 6-2 on the inner wall of the dust removing box 1 and is in threaded connection with the filter screen 5; and a spring 6-3 is sleeved between the fixing block 6-2 and the filter screen plate 5 on the T-shaped rod 6-1. When a force acts on the filter screen plate 5, the filter screen plate 5 moves downwards horizontally, and when the force disappears, the filter screen plate 5 resets.

As shown in fig. 4, the ash bucket mechanism 7 includes a fixing frame 7-1, a slider-crank mechanism 7-2 is disposed on the fixing frame 7-1, the slider-crank mechanism 7-2 includes a motor (not shown in the figure, disposed outside the dust removing box 1), the motor is coaxially connected with the turntable, a rocker is hinged on the turntable deviating from the center of the turntable, and the rocker is hinged with the hitting slider 7-3. The hitting sliding block 7-3 is opposite to the filter screen plate 5 and is arranged on a sliding rail 7-4 of the fixed frame 7-1 in a sliding manner.

By starting the motor, the hitting sliding block 7-3 moves up and down, so that the filter screen plate 5 is stressed to move up and down, and dust on the filter screen plate 5 can be shaken off to the bottom of the shell of the dust removal box 1.

The bottom of the shell of the dust removing box 1 is open and is connected with a bottom plate 21 through screw threads. When the cleaning is needed in the later period, the bottom plate 21 can be directly screwed off.

As shown in fig. 5, the water washing chamber 2 includes a housing 8, a washing bucket 9 is fixed on an upper portion inside the housing 8, a water spraying pipe 11 is fixed on the housing 8 above the washing bucket 9, and a lower end of the water spraying pipe 11 is opposite to the washing bucket 9. The pump body 12 is installed on the spray pipe 11, and the other end of the spray pipe 11 extends into the upper portion of the water body 10. Water is circulated through the water spray pipe 11.

A first air inlet pipe 13 is transversely fixed in the air washing hopper 9, and the other end of the first air inlet pipe 13 is inverted U-shaped and is connected with the first air outlet 4. The first air inlet pipe 13 is provided with air outlets at the upper and lower parts. The waste gas is sprayed out from the gas outlet and then contacts with the water body, thereby completing the water washing. In order to enable the contact between the waste gas and the water body to be more uniform, the perforated partition plate 9-3 is arranged on the upper portion of the bucket body 9-1 of the gas washing bucket 9, and water can uniformly flow down from the holes of the perforated partition plate 9-3 after entering the bucket body 9-1, so that the contact between the waste gas and the water is more uniform, and the water washing effect is improved.

The other end is connected with an elastic lifting leg 6 on the bracket 15-2. The sealing plate 15-1 is always pressed against the waste residue outlet 14 by the elasticity of the spring on the elastic lifting supporting leg 6, thereby avoiding water seepage. In addition, a corresponding sealing ring can be arranged on the end face of the sealing plate 15-1, so that water seepage is further prevented. The upper end of the bracket 15-2 is provided with a guide rod, the guide rod is provided with a nut 15-3, the guide rod on the upper part of the nut 15-3 is sleeved with a compression spring 15-4, the guide rod passes through a fixed sleeve 15-5 outside the shell 8 and then is connected with a limit plate 15-6, the limit plate 15-6 is provided with a hook 15-7, and the hook 15-7 can be connected with a hanging ring 15-8 at the upper end of the fixed sleeve 15-5.

When the waste residue outlet 14 needs to be opened, the hook 15-7 is lifted upwards manually to enable the hook 15-7 to be hung on the hanging ring 15-8, so that the sealing plate 15-1 and the support 15-2 move upwards to enable the waste residue outlet 14 to be opened, when the hook 15-7 is separated from the hanging ring 15-8, the sealing plate 15-1 is reset under the action of the compression spring 15-4, and the lower end of the support 15-2 is supported by the support plate 15-9.

In order to facilitate the overflow of dust and impurities, the bottom of the shell 8 is provided with an inclined plane 22, the inclined plane 22 is provided with a push plate 16, and the push plate 16 is in threaded connection with the screw rod 17-1. Two ends of the screw rod 17-1 are arranged on the shell 8 through bearings, and one end of the screw rod 17-1 extending out of the shell 8 is driven by a belt transmission mechanism 17-3 and a motor 17-4.

When the waste residue discharging device is not in operation, the push plate 16 is positioned on one side far away from the waste residue outlet 14, when dust impurities are accumulated to a certain height, the motor is started, the screw rod 17-1 is enabled to rotate, the push plate 16 gradually moves towards the waste residue outlet 14 and pushes the dust impurities to the waste residue outlet 14, and when the dust impurities and certain sewage are discharged through the combined action of the pushing of the push plate 16 and the inclined surface 22 when the dust impurities reach the waste residue outlet 14. Then the hook 15-7 is separated from the hanging ring 15-8, and the closing plate 15-1 moves downwards to close the waste residue outlet 14.
