A sealing port is opened on one outer wall of the treatment box, and an installation groove is opened on one inner wall of the sealing port. The inner wall of the installation groove forms a sliding fit with the filter screen plate. A sealing door is hinged on one outer wall of the treatment box, and the effect of facilitating the operation of the staff can be achieved.

[0008] One outer wall of the treatment box is rotatably connected with a rotating shaft through a bearing. A rotating plate is fixedly connected to one side of the rotating shaft. The rotating plate forms a sliding fit with the sealing door. The setting of the rotating plate can cooperate with the rotating shaft for rotation operation, and the rotation of the rotating plate can fix or loosen the sealing door.

[0009] A rotating spring is fixedly connected to the top of the rotating shaft and the outer wall of the treatment box. The setting of the rotating spring can provide elastic force for the rotating shaft and enable the rotating plate to perform a reset operation.

[0010] A soft pad is fixedly connected to the inner wall of the mounting groove. The soft pad is made of rubber and is in contact with the filter screen. The provision of the soft pad can provide a certain degree of softness to the filter screen, making it easier for the filter screen to shake up and down.

[0011] The cleaning mechanism includes a rotating motor fixedly connected to the outer wall of the processing box, the output shaft of the rotating motor is fixedly connected to the rotating shaft, the surface of the rotating shaft is fixedly connected to a cam, the cam is in contact with the filter plate, the cam is arranged to rotate when the rotating shaft rotates, and the rotation of the output shaft of the rotating motor can cause the rotating shaft to rotate.

[0012] An air inlet pipe is fixedly connected to the inner wall of the bottom of the processing box. The air inlet pipe is in a Y-shaped structure. The Y-shaped structure design can increase the exhaust path of the airflow and can fully contact the filter screen plate.

[0013] An ash discharge port is provided on the outer wall at one end of the processing box, and an ash discharge door covering the ash discharge port is hingedly connected to the outer wall at one end of the processing box. The ash discharge door can seal the ash discharge port to facilitate staff to clean dust.

[0014] The beneficial effects of the utility model are:

[0015] 1. The exhaust gas treatment device for the roasting furnace can rotate the cam by rotating the rotating shaft, and the rotation of the cam can impact the filter screen plate. The deformation of the soft pad can increase the vibration amplitude of the filter screen plate, so that the filter screen plate can be fully cleaned. After the use of the filter screen plate, the rotating plate can be rotated in conjunction with the rotating shaft, and the sealing door can be opened, and the filter screen plate can be pulled out through the inner wall of the installation groove. When cleaning the dust, the dust discharge door fixed to the processing box by a lock can be opened. Therefore, the effect of facilitating the operation of the staff can be achieved.

[0016] 2. The exhaust gas treatment device for the roasting furnace can increase the exhaust path of the airflow through the Y-shaped structure, which can fully contact with the filter plate; the ash discharge port can be sealed through the ash discharge door to facilitate the staff to clean the dust.
