[0021] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] Reference Figure 1-2As shown, a biomass particle screening device includes a screen frame 1, a screen 2, a first baffle 3, a support plate 4 and a collection box 5; the screen 2 is fixedly connected to the top of the screen frame 1 at an angle; the screen 2 is fixedly connected to the first baffle 3 symmetrically on both sides along the length direction; the lower part of the screen frame 1 is fixedly connected to the support plate 4; the collection box 5 is placed on the support plate 4. The screen frame 1 can be made by welding metal or by splicing waste materials to obtain the screen frame 1 in order to save resources; the screen 2 can be selected according to the specifications of the manufactured biomass particles. The utility model uses a stainless steel screen 2 to meet the screening requirements, which can ensure the screening effect and prevent the screen 2 from rusting during screening to affect the quality of the biomass particles. Two first baffles 3 are symmetrically arranged to prevent the biomass particles from leaking from both sides when screening the biomass particles, and can form a groove with the screen 2 to facilitate the transmission of the biomass particles; the support plate 4 is used to support the collection box 5; the collection box 5 can collect the biomass particles that do not meet the specifications that fall from the screen 2 and then re-manufacture them.

[0023] Specifically, in order to prevent the splashing of the biomass particles and debris that do not meet the specifications under the screen and to increase the time for later cleaning, two second baffles 6 are fixedly connected to both sides of the upper part of the screen frame 1 and close to the screen 2.

[0024] Specifically, in order to make the second baffle plate 6 fit closely with the upper drying rack 1 , the second baffle plate 6 is in the shape of a parallelogram.

[0025] Specifically, in order to facilitate the collection of biomass particles passing through the screen 2, the screen 2 is in the shape of an isosceles trapezoid.

[0026] Specifically, the first baffle 3 includes a strip segment 31 and an arc segment 32; the arc segment 32 is located at the upper end of the strip segment 31; the strip segment 31 and the arc segment 32 are integrally formed. The arrangement of the arc segment 32 can prevent excessive accumulation of biomass particles at the gathering place of the screen 2, causing the biomass particles to overflow.

[0027] Specifically, since biomass particles are easily accumulated at the discharge port of the screen 2 , the arc segment 32 is located near the discharge port of the screen 2 .

[0028] Specifically, in order to align the material collecting box 5 and prevent it from shaking and shifting, the support plate 4 is symmetrically provided with two stoppers 7 along the length direction.

[0029] Specifically, in order to facilitate feeding and discharging, a feed hopper 8 is fixedly connected to the upper end of the screen 2, and a discharge hopper 9 is fixedly connected to the lower end; and a connector 10 is detachably connected to the side walls of the feed hopper 8 and the discharge hopper 9.

[0030] Specifically, in order to ensure that all substandard materials under the screen fall into the collecting box 5 , the collecting box 5 is located directly below the projection of the screen 2 .

[0031] Specifically, in order to facilitate the extraction of the material collecting box 5 , a handle 11 is fixedly connected to the side wall of the pull-out end of the material collecting box 5 .

[0032] The working principle of this utility model:

[0033] The biomass particle screening device is placed between the conveyor belt and the packaging device, and then they are respectively connected through the connecting piece 10. The biomass particles transmitted from the conveyor belt are screened by the screen 2 supported by the screen frame 1, and the biomass particles that meet the requirements are delivered to the packaging device through the discharge port of the screen 2 for packaging; the biomass particles that do not meet the requirements fall from the screen 2 to the collection box 5. During this process, since the second baffles 6 are arranged on both sides of the upper end of the screen frame 1, the second baffles 6 can guide all the biomass particles that do not meet the requirements to the collection box 5 located below the screen 2, preventing the biomass particles that do not meet the requirements from scattering and ensuring the cleanliness of the production workshop; the collection box 5 is taken out by the handle 11 on the collection box 5, and then the biomass particles that do not meet the requirements in the collection box 5 are added back into the pelletizer for pelletizing.

[0034] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
