DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-4 A waste incineration power generation furnace slag screening device includes a mixing barrel 1, a control box 101 is fixedly connected to the bottom of the mixing barrel 1, a screening barrel 102 is fixedly connected to the bottom of the control box 101, and further includes:

[0025] A servo motor 2 is fixedly connected to the top of the mixing barrel 1, a rotating shaft 201 is fixedly connected to the end of the servo motor 2, and the rotating shaft 201 extends to the inner cavity of the screening barrel 102, a crushing rod 202 is fixedly connected to the side wall of the rotating shaft 201 in the inner cavity of the mixing barrel 1, a feeding pipe 208 is fixedly connected to the top of the mixing barrel 1, and a collecting cover is arranged on the top of the feeding pipe 208;

[0026] A sliding column 203 is slidably connected to the top of the mixing barrel 1, an L-shaped column 204 is fixedly connected to the side wall of the sliding column 203, and the L-shaped column 204 is located in the inner cavity of the feed pipe 208, and a first spring 205 is fixedly connected between the top of the sliding column 203 and the mixing barrel 1;

[0027] A ball 206 is fixedly connected to the bottom end of the sliding column 203, and a rotating column 207 is fixedly connected to the side wall of the rotating shaft 201;

[0028] It should be noted that: when the slag is fed into the inner cavity of the mixing barrel 1 from the feed pipe 208, the servo motor 2 is turned on, and the servo motor 2 will drive the rotating shaft 201 to rotate. During the rotation process, the rotating shaft 201 drives the crushing rod 202 to rotate, and the slag is further crushed to facilitate the subsequent screening of the screening barrel 102, and the rotating column 207 is driven to rotate during the rotation of the rotating shaft 201. The rotating column 207 collides with the ball 206, causing the ball 206, the sliding column 203 and the L-shaped column 204 to slide upward at the same time, thereby stretching the first spring 205 between the sliding column 203 and the mixing barrel 1 to generate a rebound force. When the rotating column 207 moves away from the ball 206, under the action of the rebound force of the first spring 205, the ball 206, the sliding column 203 and the L-shaped column 204 return to their original positions, thereby causing the L-shaped column 204 to move up and down in the inner cavity of the feed pipe 208, thereby preventing the slag from being blocked in the inner cavity of the feed pipe 208.

[0029] Reference Figure 1-4 The inner wall of the screening barrel 102 is slidably connected with a screening plate 3, and a second spring 301 is fixedly connected between the screening plate 3 and the inner wall of the screening barrel 102;

[0030] A cleaning component is fixedly connected to the side wall of the rotating shaft 201, and the cleaning component is fitted with the screening plate 3. A first discharge pipe 302 is fixedly connected to the top of the side wall of the screening barrel 102;

[0031] A cleaning plate 303 is fixedly connected to the side wall of the rotating shaft 201 below the screening plate 3, and the cleaning plate 303 fits the inner bottom wall of the screening barrel 102. A second discharge pipe 304 is fixedly connected to the lower side wall of the screening barrel 102.

[0032] It should be noted that the crushed slag falls on the surface of the screening plate 3, and the rotation of the rotating shaft 201 drives the cleaning component to rotate. The cleaning component will drive the slag on the surface of the screening plate 3. In this process, the screening plate 3 will be moved downward by squeezing the slag, and then the second spring 301 will be squeezed to generate a rebound force, causing the screening plate 3 to vibrate up and down, thereby enhancing the screening effect of the screening plate 3, and the slag remaining on the top of the screening plate 3 will be transferred to the inner cavity of the first discharge pipe 302 by the cleaning component, and the slag passing through the screening plate 3 will also be driven to the inner cavity of the second discharge pipe 304 by the rotating cleaning plate 303 to complete the screening.

[0033] Reference Figure 1-4 , both side walls of the control box 101 are slidably connected with a strap 305, a semicircular opening 306 is opened on the side wall adjacent to the strap 305, and the rotating shaft 201 passes through the semicircular opening 306;

[0034] The cleaning assembly includes a sleeve plate 307, a sliding plate 308 and a third spring 309. The sleeve plate 307 is fixedly mounted on the side wall of the rotating shaft 201. The sliding plate 308 is slidably connected to the inner wall of the sleeve plate 307. The third spring 309 is fixedly connected between the sliding plate 308 and the sleeve plate 307.

[0035] It should be noted that: when the take-up plate 305 is slid into the inner cavity of the control box 101, the slag will stay on the top of the take-up plate 305, thereby ensuring that the slag is fully crushed by the crushing rod 202, and then the take-up plate 305 can be slid, and the slag will fall into the top of the screening plate 3 for screening, and under the action of the third spring 309, the sliding plate 308 tends to move toward the outside of the sleeve plate 307, so that when the screening plate 3 vibrates, the sliding plate 308 can always fit with the screening plate 3, thereby ensuring that the cleaning component can drive the slag to move on the screening plate 3.

[0036] Operation method: put the slag into the inner cavity of the mixing barrel 1 from the feeding pipe 208, and the slag will stay on the top of the slat 305 at this time, turn on the servo motor 2, and the servo motor 2 will drive the rotating shaft 201 to rotate. The rotating shaft 201 drives the crushing rod 202 to rotate during the rotation process, and the slag is further crushed to facilitate the subsequent screening of the screening barrel 102. In addition, the rotating column 207 is driven to rotate during the rotation of the rotating shaft 201, and the rotating column 207 collides with the ball 206, so that the ball 206, the sliding column 203 and the L-shaped The column 204 slides upward at the same time, thereby stretching the first spring 205 between the sliding column 203 and the mixing barrel 1 to generate a rebound force. When the rotating column 207 moves away from the ball 206, the ball 206, the sliding column 203 and the L-shaped column 204 return to their original positions under the rebound force of the first spring 205, thereby making the L-shaped column 204 move up and down in the inner cavity of the feed pipe 208, thereby preventing the slag from being blocked in the inner cavity of the feed pipe 208, and then the slab 305 can be slid, and the slag falls into the top of the screening plate 3 for screening;

[0037] The crushed slag falls on the surface of the screening plate 3, and the rotation of the rotating shaft 201 drives the cleaning component to rotate. The cleaning component will drive the slag on the surface of the screening plate 3. In this process, the screening plate 3 will be moved down by squeezing the slag, and then the second spring 301 will be squeezed to generate a rebound force, causing the screening plate 3 to vibrate up and down, thereby enhancing the screening effect of the screening plate 3, and the slag remaining on the top of the screening plate 3 will be transferred to the inner cavity of the first discharge pipe 302 by the cleaning component, and the slag passing through the screening plate 3 will also be driven to the inner cavity of the second discharge pipe 304 by the rotating cleaning plate 303 to complete the screening.
