[0006] As an improvement, the bottom end of the second smoke exhaust pipe is connected to a collection box, one end of the collection box is plugged with a collection bucket, and one end of the collection box is provided with an opening that matches the collection bucket.

[0007] As an improvement, a second magnet is provided at one end of the collecting bucket, and a first magnet matching with the collecting bucket is provided on the inner wall of the collecting box.

[0008] As an improvement, a connecting rod is provided at the top end of the second smoke exhaust pipe, and a conical baffle is provided at the top end of the connecting rod.

[0009] As an improvement, a controller electrically connected to the motor is provided on the furnace body.

[0010] As an improvement, the cross section of the filter is fan-shaped, and a plurality of filters are arranged on the circumference of the frame.

[0011] As an improvement, the bristles are located at the lower end of the filter.

[0012] The beneficial effects of the utility model are as follows: the filter screen can be cleaned by the cleaning component so that particles on the filter screen fall off, thereby avoiding poor smoke discharge, and the filter screen does not need to be manually removed, which is convenient and quick.

[0020] The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1 , Figure 3 As shown, a catalyst roasting furnace comprises a furnace body 1, a first smoke exhaust pipe 2 is connected to the furnace body 1, one end of the first smoke exhaust pipe 2 is connected to a second smoke exhaust pipe 3, a plurality of filter screens 8 are arranged on the inner circumference of the second smoke exhaust pipe 3, the cross sections of the plurality of filter screens 8 are fan-shaped, the longitudinal section of the first smoke exhaust pipe 2 is an inverted L-shape, the second smoke exhaust pipe 3 is arranged vertically, a frame 7 is arranged inside the second smoke exhaust pipe 3, the filter screen 8 is connected to the frame 7, a connecting rod is arranged at the top end of the second smoke exhaust pipe 3, and a conical shield 4 is arranged at the top end of the connecting rod to prevent rainwater from entering the second smoke exhaust pipe 3;

[0022] like Figure 3 , Figure 4As shown, the frame 7 is connected to a cleaning assembly, which includes a motor 9 connected to the frame 7, a rotating shaft 11 drivingly connected to the motor 9, and a connecting plate 12 connected to the rotating shaft 11. The connecting plate 12 is provided with an array of bristles 13 that match the filter 8. The bristles 13 are located at the lower end of the filter 8 to facilitate cleaning the filter 8. A controller electrically connected to the motor 9 is provided on the furnace body 1 to facilitate controlling the rotation of the motor 9.

[0023] like Figure 5 As shown, the bottom end of the second smoke exhaust pipe 3 is connected to a collecting box 5, one end of the collecting box 5 is plugged with a collecting bucket 6, one end of the collecting box 5 is provided with an opening that matches the collecting bucket 6, one end of the collecting bucket 6 is provided with a second magnet 10, and the inner wall of the collecting box 5 is provided with a first magnet that matches the collecting bucket 6, so as to facilitate fixing the collecting bucket 6 to the collecting box 5.

[0024] Working principle: When the furnace body 1 is calcining the catalyst, the smoke generated by the furnace body 1 enters the second smoke exhaust pipe 3 through the first smoke exhaust pipe 2, and the smoke passes through the filter 8 from bottom to top and is discharged from the top of the second smoke exhaust pipe 3, while the particles are intercepted by the filter 8;

[0025] When the filter 8 needs to be cleaned, the furnace body 1 stops roasting, and the motor 9 drives the connecting plate 12 to rotate around the rotating shaft 11 through the rotating shaft 11. The connecting plate 12 drives the bristles 13 to clean the bottom end of the filter 8, and the particles fall into the collecting bucket 6 and are collected.
