Through the above scheme, the problem that the existing pneumatic separation device for wood chip processing blows air continuously into the interior and cannot discharge the air to form a backflow, thereby affecting the pneumatic separation of impurities, dust and other items, is solved.

[0023] For this specific embodiment, the main box 101 restricts the range of wood chip pneumatic separation, ensuring that the wood chips do not fly around during pneumatic separation.

[0024] Among them, the feeding part 103 is arranged on one side of the main box 101. The main box 101 has an air inlet 110, and the air inlet 110 is located on one side of the main box 101. The support frame 104 is fixedly connected to the main box 101 and is located on one side of the main box 101.

The main box 101 also has a circulation hole 111, and the circulation hole 111 is located on one side of the main box 101. The second filter screen 108 is slidably connected to the main box 101 and is located on one side of the main box 101. The installation cover 109 is threadedly connected to the main box 101 and is located on one side of the main box 101. Wood chips are put into the feeding part 103, and the feeding part 103 is used to convey the wood chips. The support frame 104 is installed at the position of the air inlet 110. The gaps of the support frame 104 are filled by the first filter screen 105 to filter the flowing air. The fan 106 is fixed on the side of the support frame 104 closer to the inside of the main box 101. The air is continuously blown from the outside to the inside through the diversion of the fan 106. By adjusting the blowing magnitude of the fan 106, when the wood chips fall from the feeding part 103, the wood chips and impurities are separated by air separation due to different blowing distances of the wood chips and impurities. The air blown into the inside will be discharged from the circulation hole 111 on the other side to form a cycle. During the discharging process, the second filter screen 108 is fixed at the position of the circulation hole 111 through the installation cover 109 to filter the discharged air and prevent the discharged impurities from affecting the environment. Part of the blocked impurities are adsorbed on the second filter screen 108, and the second filter screen 108 is removed for cleaning by unscrewing the installation cover 109. The other part slides down through the collection plate 107 and then is collected and processed uniformly. The air separation inside the main box 101 forms a circulating effect, and the impurities and wood boards are distinguished more efficiently.

[0025] Secondly, the main box 101 has a feed inlet 112, which is located on one side of the main box 101. The feed hopper 113 is slidably connected to the main box 101 and is located on one side of the main box 101.

The second inclined plate 117 is fixedly connected to the main box 101 and is located on one side of the main box 101. Insert the feed hopper 113 into the feed inlet 112, then converge the wood chips from the feed hopper 113 and let them fall onto the mounting seat 114. After that, the conveyor belt 115 drives the wood chips to move on the surface of the mounting seat 114, driving the wood chips towards the positions of the first inclined plate 116 and the second inclined plate 117, and guiding them to fall obliquely through the first inclined plate 116 and the second inclined plate 117 to lengthen the falling time. Use the blower 106 to perform air separation on the falling wood chips to separate the impurities from the wood chips.

[0026] Meanwhile, a plurality of the collection boxes 118 are slidably connected to the main box 101 and are respectively located on one side of the main box 101. A plurality of the pulling members 119 are fixedly connected to the collection boxes 118 and are respectively located on one side of the collection boxes 118. There are a plurality of the collection boxes 118, which separately collect the wood chips and the impurities, facilitating subsequent cleaning. Each of the collection boxes 118 is provided with the pulling member 119. By pulling the pulling member 119, the collection box 118 can be quickly pulled out for easy cleaning.

[0027] In addition, the partition plate 121 is fixedly connected to the main box 101 and is located on one side of the main box 101. The guide plate 120 is fixedly connected to the partition plate 121 and is located on one side of the partition plate 121. The collection box 118 is separated by the partition plate 121, and the two sides of the collection box 118 are provided with the guide plates 120. The guide plates 120 cover the partition plate 121 to prevent it from staying on the partition plate 121, and the guide plates 120 guide the falling wood chips and impurities to separate and store them.

[0028] When using the present utility model, wood chips are put into the feeding part 103, the feeding hopper 113 is inserted into the feeding port 112, and then the wood chips are converged from the feeding hopper 113 and fall onto the mounting seat 114. After that, the conveyor belt 115 drives the wood chips to move on the surface of the mounting seat 114, driving the wood chips towards the positions of the first inclined plate 116 and the second inclined plate 117, and guiding and tilting them to fall through the first inclined plate 116 and the second inclined plate 117 to lengthen the falling time. The blower 106 is used to perform air separation on the falling wood chips. The support frame 104 is installed at the position of the air inlet 110, and the gaps of the support frame 104 are filled by the first filter screen 105 to filter the flowing air. The blower 106 is fixed on one side of the support frame 104 inside the main box 101. Through the diversion of the blower 106, air is continuously blown from the outside to the inside. Adjust the blowing magnitude of the blower 106. When the wood chips fall from the feeding part 103, the wood chips and impurities are separated by air separation due to different blowing distances of the wood chips and impurities. The air blown into the interior will be discharged from the circulation hole 111 on the other side to form a cycle. During the discharging process, the second filter screen 108 is fixed at the position of the circulation hole 111 through the mounting cover 109 to filter the discharged air and prevent the discharged impurities from affecting the environment. A part of the blocked impurities is adsorbed on the second filter screen 108, and the second filter screen 108 is removed and cleaned by unscrewing the mounting cover 109. Another part slides down through the collection plate 107 and falls into the collection frame 118 to prevent impurities from staying and floating inside the main box 101. The air separation inside the main box 101 forms a circulating effect, and the impurities and wood boards are distinguished more efficiently.

[0029] The second embodiment of this application is as follows:

[0030] On the basis of the first embodiment, please refer to Figures 4 - 5 , wherein, Figure 4 is the overall structural schematic diagram of the second embodiment of the present utility model, Figure 5 is the overall cross-sectional view of the second embodiment of the present utility model. An air separation device for wood chip processing provided by the present utility model further includes a flow limiting component 201. The flow limiting component 201 includes a flow limiting plate 202 and a transparent observation window 203.

[0031] For this specific embodiment, the flow limiting component 201 is arranged on one side of the main box 101, and the flow limiting component 201 limits the number of wood chips transported by the conveyor belt 115, so as not to affect the quality of air separation due to excessive quantity.

[0032] Among them, the current-limiting plate 202 is fixedly connected to the main box 101 and is located on one side of the main box 101. The transparent observation window 203 is fixedly connected to the main box 101 and is located on one side of the main box 101. The current-limiting plate 202 limits the flow of wood chips on the conveyor belt 115 to ensure that too many wood chips do not fall at one time, thus affecting the effect of air separation. When feeding the wood chips, the transportation situation can be observed through the transparent observation window 203, and the feeding speed can be increased or decreased according to the transportation situation.

[0033] When using the present utility model, the wood chips are put into the feeding part 103, the feeding hopper 113 is inserted into the feeding port 112, and then the wood chips are collected from the feeding hopper 113 and fall onto the mounting seat 114. After that, the conveyor belt 115 drives the wood chips to move on the surface of the mounting seat 114. The current-limiting plate 202 limits the flow of wood chips on the conveyor belt 115 to ensure that not too many wood chips fall at one time, thus affecting the effect of air separation. When feeding the wood chips, the transportation situation can be observed through the transparent observation window 203, and the feeding speed can be increased or decreased according to the transportation situation. The conveyor belt 115 drives the wood chips to the positions of the first inclined plate 116 and the second inclined plate 117, and the wood chips fall obliquely through the guidance of the first inclined plate 116 and the second inclined plate 117 to lengthen the falling time. The blower 106 is used to perform air separation on the falling wood chips. The support frame 104 is installed at the position of the air inlet 110, and the gaps of the support frame 104 are filled with the first filter screen 105 to filter the flowing air. The blower 106 is fixed on one side of the support frame 104 closer to the inside of the main box 101. Through the diversion of the blower 106, the air is continuously blown from the outside to the inside. Adjust the blowing size of the blower 106. When the wood chips fall from the feeding part 103, the wood chips and impurities are separated by air separation because the blowing distances of the wood chips and impurities are different. The air blown into the interior will be discharged from the other circulation hole 111 to form a cycle. During the discharging process, the second filter screen 108 is fixed at the position of the circulation hole 111 through the mounting cover 109 to filter the discharged air and prevent the discharged impurities from affecting the environment. A part of the blocked impurities is adsorbed on the second filter screen 108, and the second filter screen 108 is removed by unscrewing the mounting cover 109 for cleaning. The other part slides down through the collecting plate 107 and falls into the collecting frame 118 to prevent the impurities from staying and floating inside the main box 101. The air separation inside the main box 101 forms a circulating effect, and the impurities and wood boards can be distinguished more efficiently.

[0034] The above disclosure is only one or more preferred embodiments of the present application, and it cannot be used to limit the scope of rights of the present application. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
