[0017] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:
[0018] like Figure 1 、 2 As shown, a reed particleboard raw material purification and separation device includes a separation cylinder 1 and a feed pipe 2 and a discharge pipe 3 fixedly connected on both sides of its upper portion. A deflector 5 is installed in the separation cylinder 1 between the feed pipe 2 and the discharge pipe 3. An air lock discharger 4 is installed at the bottom outlet of the separation cylinder 1. The air lock discharger 4 adopts a star-shaped discharger arrangement, which relies on a rotating impeller to transport materials and also plays a sealing role to prevent air from being sucked into the discharge port during pneumatic conveying.
[0019] like Figure 4 As shown, the baffle 5 is arranged vertically to the feed pipe 2 and its cross-sectional shape is V-shaped. The V-shaped baffle 5 acts as a barrier to change the moving direction of the reeds and sand and gravel, so that the sand and gravel with larger specific gravity move downward. The baffle 5 is fixed to the lower part of the top cover 6 installed on the top of the separation cylinder 1.
[0020] like Figure 3 As shown, the upper parts of both ends of the baffle 5 are connected with plug blocks 7, and the plug blocks 7 are inserted into the insertion rails 8 fixed at the lower part of the top cover 6. By plugging and fixing the plug blocks 7 and the insertion rails 8, the baffle 5 can be quickly disassembled and assembled, and subsequent maintenance is more convenient.
[0021] like Figure 4 As shown, the top cover 6 and the insert block 7 are provided with matching positioning holes 10, and the positioning holes 10 are screwed with positioning bolts 9 that limit the baffle 5. The positioning bolts 9 are inserted to position the insert block 7, thereby preventing the insert block 7 from moving in the lower part of the top cover 6.
[0022] The bottom of the baffle 5 extends downward to the lowest point of the feed pipe 2, so that all the materials transported through the feed pipe 2 will be deflected by the baffle 5 to change the direction of movement, preventing sand and gravel with a larger specific gravity from directly entering the discharge pipe 3 for discharge.
[0023] The top cover 6 is detachably connected to the top of the separation cylinder 1 by a plurality of bolts.
[0024] The implementation principle of the reed particleboard raw material purification and separation device in the embodiment of the present application is as follows:
[0025] The crushed reed raw material (containing sediment) enters the separation cylinder 1 for heavy object separation through the pneumatic conveying feed pipe 2, and is refracted downward under the blocking effect of the V-shaped baffle 3. During the downward refraction movement of the material, impurities such as sand and stones with relatively large specific gravity continue to move downward under the dual effects of gravity and refraction and fall to the bottom outlet of the separation cylinder 1. The sand and gravel impurities accumulated at the bottom of the separation cylinder 1 are discharged from the system through the air lock discharger 4. The function of the air lock discharger 4 is to seal the airflow to prevent external air from entering the system and affecting the sedimentation effect of the heavy objects;
[0026] The reed crushed materials with lighter specific gravity will move along the lower area of the baffle 5 and eventually be discharged from the discharge pipe 3 on the back of the baffle 5 (the reed crushed materials will form a buffer zone inside the separation cylinder 1, and the airflow entering the separation cylinder 1 will eventually carry the reed crushed materials with smaller specific gravity and be discharged from the discharge pipe 3). In this way, the separation of impurities in the reed crushed materials is achieved, and the clean reed materials separated from the sand and gravel enter the next production process through the pneumatic conveying pipeline. At the same time, the device can also be promoted and used in the production process of non-wood artificial boards using crop straw (wheat straw, rice straw, corn straw, etc.) as materials;
[0027] When the lower part of the baffle 5 is severely worn after long-term use, the top cover 6 can be opened to remove the lower baffle 5. When removing it, loosen the positioning bolts 9 and pull the baffle 5 out of the insertion rail 8 through the plug blocks 7 on both sides to achieve quick disassembly of the baffle 5 and the top cover 6. After disassembly, replacement and maintenance are convenient and efficient.
[0028] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
