[0020] See also Figure 1-Figure 3 , the utility model provides two technical solutions: Embodiment 1

[0021] See also Figure 1 In the embodiment of the utility model, the wood pulp filtering device for the board includes a collecting box 1, and limit seats 2 are arranged at the four upper corners of the collecting box 1. A conveyor belt 3 is arranged between the four limit seats 2, and a filter belt 4 is arranged at the middle part of the conveyor belt 3. The wood pulp filtering device for the board also includes a filter pressing mechanism 5 for filtering the wood pulp.

[0022] See also Figure 2-Figure 3 In the embodiment of the utility model, the filter press mechanism 5 includes a concave seat 51, and limit plates 52 are arranged at both ends of the concave seat 51. Two pressure rollers 57 corresponding to the filter belt 4 are symmetrically rotated between the two limit plates 52, and two limit shafts 53 are horizontally symmetrically connected to the upper side of the concave seat 51. A moving plate 54 is horizontally slidably sleeved between the outer parts of the two limit shafts 53, and a plurality of scraper rods 55 are equidistantly arranged at the lower part of the moving plate 54. A reduction motor 58 for driving the pressure roller 57 to rotate is installed on the side of one of the limit plates 52 away from the pressure roller 57, and a transmission mechanism 56 is arranged on the side of the other limit plate 52 away from the pressure roller 57.

[0023] See also Figure 2-Figure 3 In the embodiment of the utility model, the transmission mechanism 56 includes two transmission wheels 561 rotatably arranged on the side of the limiting plate 52 away from the pressure roller 57, one end of the two transmission wheels 561 is respectively connected to one end of the two pressure rollers 57, a transmission disk 562 is rotatably arranged on one side of the concave seat 51, the transmission disk 562 and the two transmission wheels 561 are connected through a transmission belt 563, a connecting rod 564 is hinged at the edge of the side of the transmission disk 562 away from the concave seat 51, and one end of the connecting rod 564 away from the transmission disk 562 is hinged to one side of the movable plate 54.

[0024] In the above scheme: when the reduction motor 58 rotates, it will drive the pressure roller 57 to rotate, and the pressure roller 57 drives the transmission wheel 561 to rotate. The transmission wheel 561 makes the transmission belt 563 drive another transmission wheel 561 to rotate, and the other transmission wheel 561 will drive the pressure roller 57 connected thereto to rotate. When the two pressure rollers 57 rotate, the wood pulp on the filter belt 4 will be squeezed and filtered. When the transmission wheel 561 rotates, the transmission wheel 561 will also make the transmission belt 563 drive the transmission disk 562 to rotate, and the transmission disk 562 drives the connecting rod 564 to make an eccentric movement, and the connecting rod 564 will drive the movable plate 54 to slide back and forth on the limiting shaft 53, and the scraper rod 55 at the bottom of the limiting shaft 53 will scrape and disperse the wood pulp accumulated on the filter belt 4, so as to facilitate the pressure roller 57 to filter the wood pulp.

[0025] For further information, see Figure 1 In the embodiment of the utility model, the outside of the conveyor belt 3 is provided with a separation belt 31 at both sides of the filter belt 4. The separation belt 31 is made of elastic material and has a barrier effect on the wood pulp to prevent wood pulp chips from mixing into the collection box 1.

[0026] For further information, see Figure 3 In the embodiment of the utility model, the lower end of the scraper rod 55 is flush with the lower side of the pressure roller 57. When the pressure roller 57 moves, the scraper rod 55 also moves, so that the scraper rod 55 can contact the wood pulp, so as to scrape and disperse the wood pulp.

[0027] The second embodiment is different from the first embodiment in that:

[0028] See also Figure 2 In the embodiment of the utility model, the filter pressing mechanism 5 also includes an L-shaped seat 59 arranged at the upper edge of the collecting box 1, the top side of the L-shaped seat 59 is located above the concave seat 51, and an adjusting hydraulic cylinder 510 is installed on the top side of the L-shaped seat 59, and the output shaft of the adjusting hydraulic cylinder 510 is connected to the top of the concave seat 51. During the filtration, according to the amount of wood pulp, the adjusting hydraulic cylinder 510 drives the concave seat 51 to move downward, and then drives the two pressing rollers 57 to move downward, and adjusts the pressing rollers 57 to a suitable position, thereby controlling the force of the filtration.

[0029] For further information, see Figure 1 In the embodiment of the utility model, a material guide plate 101 is arranged at an upward tilt at the upper edge of one side of the collecting box 1. The side of the material guide plate 101 away from the collecting box 1 contacts one side of the filter belt 4. After the filtering is completed, under the action of the material guide plate 101, the material guide plate 101 can scrape the wood pulp on the filter belt 4 to complete the unloading of the wood pulp chips.

[0030] The working principle of the above structure is as follows: the wood pulp is poured onto the filter belt 4, the filter belt 4 filters the wood pulp, and the filtered wood pulp liquid falls into the collection box 1. The separation belt 31 blocks the wood pulp to prevent the wood pulp chips from mixing into the collection box 1. After the filtration is completed, under the action of the guide plate 101, the guide plate 101 can scrape the wood pulp on the filter belt 4 to complete the unloading of the wood pulp chips.

[0031] During the filtration, according to the amount of wood pulp, the adjusting hydraulic cylinder 510 drives the concave seat 51 to move downward, and then drives the two pressing rollers 57 to move downward, and adjusts the pressing rollers 57 to a suitable position. When the reduction motor 58 rotates, it drives the pressing rollers 57 to rotate, and the pressing rollers 57 drive the transmission wheel 561 to rotate. The transmission wheel 561 makes the transmission belt 563 drive another transmission wheel 561 to rotate, and the other transmission wheel 561 drives the pressing roller 57 connected thereto to rotate. When the two pressing rollers 57 rotate, the wood pulp on the filter belt 4 is squeezed and filtered;

[0032] When the transmission wheel 561 rotates, the transmission wheel 561 will also cause the transmission belt 563 to drive the transmission disk 562 to rotate, and the transmission disk 562 will drive the connecting rod 564 to make eccentric movement. The connecting rod 564 will drive the movable plate 54 to slide back and forth on the limiting shaft 53, and the scraper rod 55 at the bottom of the limiting shaft 53 will scrape and disperse the wood pulp accumulated on the filter belt 4, so as to facilitate the pressing roller 57 to filter the wood pulp.

[0033] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.
