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

[0024] See also Figures 1 to 3 The utility model provides a technical solution: a screening device for biomass particle combustion processing, comprising a screening drum 1, a guide assembly 200 is installed on the inner side of the screening drum 1, a screening assembly 300 is installed on the inner side of the screening drum 1, and a crusher body 4 is installed on the bottom of the screening drum 1; through the coordinated use of the guide assembly 200 on the inner side of the screening drum 1 and the screening assembly 300, the biomass particles can be screened more effectively, and through the vertical setting and the coordination of the internal limiting structure, the movement path of the particles can be specified, so that they can be effectively screened, thereby improving the screening efficiency and the actual screening effect, thereby effectively improving the practicality of the screening device for biomass particle combustion processing.

[0025] In this embodiment, the screening assembly 300 is a structure for screening biomass particles.

[0026] like Figure 1 、 Figure 2 and Figure 3 As shown, the screening assembly 300 includes a partition plate 301 fixed to the inner bottom wall of the screening drum 1, an inclined block 302 fixed to the inner bottom wall of the screening drum 1, an output pipe 303 fixed to the bottom of the screening drum 1 and connected to the interior thereof, a mounting box 304 fixed to the right inner wall of the screening drum 1, a servo motor 305 fixedly mounted on the right side of the screening drum 1, a rotating shaft 306 rotatably connected to the right inner wall of the screening drum 1 through a bearing, a rotating rod 307 fixed to the left end of the rotating shaft 306, and a rotating shaft 308 hinged to the left end of the rotating shaft 308. A connecting rod 308 at the bottom left end of the rotating rod 307, a screening mesh plate 309 hinged to the top of the partition plate 301 through a pin, a movable plate 310 fixed to the top of the screening mesh plate 309, a movable hole 311 opened on the left side of the installation box 304 for the screening mesh plate 309 to move, two dust curtains 312 respectively fixed to the top and bottom of the screening mesh plate 309, a guide shell 313 fixed to the left side of the installation box 304, and two vertical plates 314 fixed to the bottom of the guide shell 313.

[0027] It should be noted that the front and back sides of the partition plate 301 are fixedly connected to the inner front side wall and the inner rear side wall of the screening drum 1 respectively, so that the partition plate 301 can divide the interior of the screening drum 1 into two spaces, the left side of the inclined block 302 is fixedly connected to the right side of the partition plate 301, and the front and back sides of the inclined block 302 are fixedly connected to the inner front side wall and the inner rear side wall of the screening drum 1 respectively, and the top of the inclined block 302 is inclined toward the side close to the output pipe 303, so that the particulate material on the right side of the partition plate 301 can be moved to the inside of the output pipe 303 under the action of the inclined block 302 and then discharged.

[0028] In addition, the output shaft of the servo motor 305 passes through the right side of the screening drum 1 and is fixedly connected to the right end of the rotating shaft 306. The rotating shaft 306, the rotating rod 307, the connecting rod 308, and the movable plate 310 are all located inside the installation box 304, so that the servo motor 305 can drive the rotating shaft 306 to rotate, and then allow the rotating rod 307 to rotate, which can protect it under the action of the installation box 304.

[0029] At the same time, the right side of the movable plate 310 is hinged to the left side of the connecting rod 308 through a pin shaft, so that when the rotating rod 307 rotates, the connecting rod 308 can be pulled to move, and the hinged action at the bottom end of the connecting rod 308 can drive the movable plate 310 to move, and then the screening mesh plate 309 is rotated by being hinged with the top of the partition plate 301 to realize the reciprocating swing function. The two dust-proof curtains 312 are fixedly connected to the top and bottom of the movable hole 311 on the opposite sides respectively. The dust-proof curtains 312 are wrinkled and have a certain tensile capacity, so that the screening mesh plate 309 can drive the dust-proof curtains 312 to move normally during the reciprocating swing process, so that the dust-proof curtains 312 can play a protective blocking role for the opening of the movable hole 311 to prevent particulate matter from entering.

[0030] In this embodiment, the guide assembly 200 is a structure for guiding biomass particles.

[0031] like Figure 1 As shown, the guide assembly 200 includes a conical cylinder 201 fixed to the top of the screening cylinder 1 and connected to the interior thereof, an inlet pipe 202 fixedly installed on the top of the conical cylinder 201, a first guide plate 203 fixed to the right side wall of the screening cylinder 1, a second guide plate 204 fixed to the left side wall of the screening cylinder 1, two parallel plates 205 respectively fixed to the left side of the first guide plate 203 and to the right side of the second guide plate 204, and a discharge pipe 206 fixed to the bottom of the screening cylinder 1 and fixedly connected to the top of the crusher body 4.

[0032] It should be noted that the first guide plate 203 and the second guide plate 204 are both inclined downward, and the front and back surfaces of the first guide plate 203 and the second guide plate 204 are fixedly connected to the inner front side wall and the inner rear side wall of the screening drum 1 respectively. The left side of the first guide plate 203 extends to the left side above the second guide plate 204, and the right side of the second guide plate 204 extends to the left side of the installation box 304. The parallel plate 205 is arranged parallel to the inner bottom wall of the screening drum 1, so that the particulate material entering the interior of the screening drum 1 through the conical drum 201 can move to the left side of the top of the second guide plate 204 under the action of the first guide plate 203 and the top parallel plate 205, and then move to the left side of the installation box 304 through the top of the second guide plate 204 and the action of the bottom parallel plate 205, and then fall on the top of the screening mesh plate 309.

[0033] At the same time, the interior of the discharge pipe 206 is connected to the interior of the crusher body 4, so that the particles inside the discharge pipe 206 can enter the interior of the crusher body 4 for crushing. The crusher body 4 includes an outer shell, a motor, and a crushing blade. The motor drives the crushing blade to rotate, thereby crushing the particles. A recovery pipe is also fixed to the bottom of the outer shell for discharging the crushed material particles. This is an existing disclosed technology, so I will not elaborate on it.

[0034] In addition, the front and back of the guide shell 313 are fixedly connected to the inner front side wall and the inner rear side wall of the screening drum 1 respectively, and the left and right sides and the bottom of the guide shell 313 are open. The two vertical plates 314 are symmetrically distributed front to back. The distance between the two vertical plates 314 is smaller than the width of the guide shell 313. The bottom parallel plate 205 is located inside the guide shell 313 and above the vertical plates 314. The screening mesh plate 309 is located between the bottoms of the two vertical plates 314, so that the particles conveyed at the top of the second guide plate 204 can move to the inside of the guide shell 313 through the corresponding parallel plates 205, and then under the cooperative limiting action of the two vertical plates 314, the conveyed particles can be blocked and limited to a certain extent, so that they can fall normally on the top of the screening mesh plate 309, thereby facilitating efficient screening.

[0035] The working principle of the above embodiment is:

[0036] When screening the biomass particles undergoing combustion processing, the particles are allowed to enter the interior of the conical cylinder 201 through the inlet pipe 202, and are guided by the first guide plate 203 to move to the left side of the top of the second guide plate 204, and slide to the right side at the top of the second guide plate 204. Under the action of the parallel plate 205, the particles can play a certain deceleration role when sliding out from the first guide plate 203 and the top of the second guide plate 204, so that the particles sliding out from the top of the second guide plate 204 can move to the top of the screening mesh plate 309 for screening. The servo motor 305 is started to drive the rotating shaft 306 to rotate, so that the rotating rod 307 rotates and drives the connecting rod 308. The top of the connecting rod 308 moves, and the movable plate 310 is pulled or pushed to move in the longitudinal direction under the hinged action of the bottom end of the connecting rod 308, so that the screening mesh plate 309 can swing back and forth, so that the particles on the top of the screening mesh plate 309 can be driven up and down to move, thereby increasing the screening effect and efficiency. The particles that pass the screening move to the right side of the partition plate 301 and are discharged through the output pipe 303 under the action of the top slope of the inclined plane block 302. The particles that do not pass the screening move to the left side of the partition plate 301 and enter the interior of the crusher body 4 through the discharge pipe 206 for crushing processing, and then are discharged after processing, thereby facilitating the normal progress of the combustion processing.

[0037] Compared with the prior art, the screening device for biomass particle combustion processing can more effectively screen the biomass particles through the coordinated use of the guide assembly 200 and the screening assembly 300 on the inner side of the screening cylinder 1, and through the vertical setting and the coordination of the internal limiting structure, the movement path of the particles can be specified, so that they can be effectively screened, thereby improving the screening efficiency and the actual screening effect, thereby effectively improving the practicality of the screening device for biomass particle combustion processing, and solving the problem that the existing screening device for biomass fuel particles has poor screening effect on biomass particles piled together.
