Description

Technical Field

[0001] The utility model relates to the technical field of particle air separation devices, in particular to a particle air separation device for producing particle boards. Background Technique

[0002] Particle boards, also known as chipboards, are made by cutting various branches, small-diameter logs, fast-growing woods, wood chips, etc. into fragments of a certain specification, drying them, and mixing them with adhesives, hardeners, waterproofing agents, etc., and pressing them into a type of artificial board under a certain temperature and pressure. The particles are unevenly arranged, and since the particles are of different sizes, in order to facilitate the production of particle boards, it is necessary to perform an air separation operation on the particles so that qualified particles are screened out, and the oversized particles are reworked.

[0003] When the particles are placed in the air separation device, due to their different sizes, the particles accumulate together. If the air separation is directly carried out, the air separation effect of the particles will be reduced. Moreover, the air separation of particles is mostly based on the different weights of the particles to separate particles of different sizes. However, this method will cause small stones in the particles to fall together with the heavier particles, affecting the subsequent processing of the large particles. In addition, a large amount of dust will be generated during the air separation process of the particles, resulting in air pollution and being inhaled by people, which is harmful to physical health. Content of the Utility Model

Through the provided screening component 6, impurities such as stones that fall together with the heavier wood chips can be separated, which is convenient for reworking the heavier wood chips in the later stage. Through the provided dust removal component 7, the dust generated during the air separation of the wood chips can be filtered to prevent the dust from entering the external air and causing environmental pollution.

[0024] Please refer to Figure 2 , a partition 101 is fixedly connected to the middle of the inner surface of the air separation box 1.

[0025] A fixing frame 201 is fixedly connected to the right side of the inner surface of the air inlet pipe 2. A first motor 202 is fixedly connected to the middle of the fixing frame 201. An output end of the first motor 202 is fixedly connected to a fan 203.

[0026] By the first motor 202 and the fan 203, the wood shavings inside the air separation box 1 can be air-selected. The wood shavings with larger mass and impurities such as stones will fall to the right side of the partition 101, and the wood shavings with smaller mass will be blown to the left side of the partition 101, separating the air-selected wood shavings of different sizes.

[0027] Please refer to Figure 3 , the dispersion assembly 4 includes a dispersion barrel 401. A second motor 402 is fixedly connected to the middle of the right surface of the dispersion barrel 401. A plurality of connecting rods 403 are fixedly connected to the surface of the output shaft of the second motor 402 in an annular array through the inside of the dispersion barrel 401. One end of the connecting rod 403 far from the output shaft of the second motor 402 is fixedly connected to a stirring plate 404. A spiral blade 405 is fixedly connected to the surface of the stirring plate 404. A feeding port 406 is connected through the upper left side of the outer surface of the dispersion barrel 401.

[0028] By driving the connecting rod 403 to rotate by the second motor 402, the stirring plate 404 is driven to rotate. By driving the spiral blade 405 to rotate through the stirring plate 404, the stirring plate 404 can disperse the wood shavings of different sizes piled together, facilitating the air selection of the wood shavings. The spiral blade 405 can convey the wood shavings inside the dispersion barrel 401 into the feeding pipe 3 and enter the air separation box 1 through the feeding pipe 3.

[0029] Please refer to Figure 4 , the screening assembly 6 includes a third motor 601. The third motor 601 is fixedly connected to the middle of the lower part of the right surface of the air separation box 1. The output shaft of the third motor 601 penetrates through the inside of the air separation box 1 and is fixedly connected to two eccentric wheels 602 arranged parallel to each other left and right. A screen 603 is arranged above the eccentric wheels 602. Fixed rods 604 are slidably connected to the four corners of the screen 603. Buffer springs 605 are sleeved on the surface of the fixed rods 604 below the screen 603.

[0030] By driving the two eccentric wheels 602 on the left and right to rotate by the third motor 601, when the eccentric wheels 602 contact the upper screen 603, the screen 603 will move upward. When the eccentric wheels 602 no longer contact the screen 603, the screen 603 will move downward under the action of gravity, jittering the wood shavings with larger mass above the screen 603 to make the impurities such as stones inside fall below the screen 603.

[0031] Please refer toFigure 5 , the dust removal assembly 7 includes a dust removal barrel 701. A jack 702 penetrating the inner and outer surfaces is provided in the middle of the front surface of the dust removal barrel 701. A filter screen 703 is slidably connected inside the jack 702. A partition net 704 is fixedly connected to the right surface of the dust removal barrel 701. A communicating pipe 705 is connected through the middle of the left surface of the dust removal barrel 701, and the other end of the communicating pipe 705 is connected through the lower part of the outer surface of the air inlet pipe 2.

[0032] When performing shaving screening, the generated dust will enter the dust removal barrel 701 through the partition net, and the dust will be filtered by the filter screen 703. The filtered gas will enter the air inlet pipe 2 through the communicating pipe 705 and be blown into the air separation box 1 again, preventing dust from entering the external air and polluting the air. When there is a lot of dust accumulated on the surface of the filter screen 703, the filter screen 703 can be directly pulled out from the inside of the jack 702, and then the filter screen can be replaced.

[0033] Working principle: When using this equipment, first put the shavings to be sorted into the dispersion barrel 401 through the feeding port 406. Drive the connecting rod 403 to rotate through the second motor 402, and then drive the stirring plate 404 to rotate. Drive the spiral blade 405 to rotate through the stirring plate 404. The stirring plate 404 can disperse the shavings of different sizes piled together, facilitating the air separation of the shavings. The spiral blade 405 can convey the shavings in the dispersion barrel 401 into the feeding pipe 3 and enter the air separation box 1 through the feeding pipe 3. At this time, the first motor 202 and the fan 203 can perform air separation on the shavings in the air separation box 1. The shavings with larger mass and impurities such as stones after air separation will fall to the right side of the partition plate 101, and the shavings with smaller mass will be blown to the left side of the partition plate 101. Drive the left and right eccentric wheels 602 to rotate through the third motor 601. When the eccentric wheel 602 contacts the upper screen 603, the screen 603 will move upward. When the eccentric wheel 602 no longer contacts the screen 603, the screen 603 will move downward under the action of gravity, shaking the shavings with larger mass above the screen 603 to make the impurities such as stones inside fall below the screen 603, facilitating the rework of the shavings with larger mass. When performing shaving screening, the generated dust will enter the dust removal barrel 701 through the partition net, and the dust will be filtered by the filter screen 703. The filtered gas will enter the air inlet pipe 2 through the communicating pipe 705 and be blown into the air separation box 1 again, preventing dust from entering the external air and polluting the air. When there is a lot of dust accumulated on the surface of the filter screen 703, the filter screen 703 can be directly pulled out from the inside of the jack 702, and then the filter screen can be replaced. After the air separation work is completed, open the two side closing doors 8 in sequence to take out the shavings after air separation inside the air separation box 1.
