DETAILED DESCRIPTION

It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this embodiment can be combined with each other. The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Referring to FIGS. 1 to 4 , the purpose of this embodiment is to provide a multi-stage screener with adjustable screen particle diameter, including a screen plate 1, a discharge plate 101 fixedly mounted at one end of the screen plate 1, a main frame 105 fixedly mounted at the lower end of the screen plate 1, a receiving platform 2 provided at the lower end of the main frame 105, and further comprising:

The vibration mechanism 3 includes a first fixed block 301, which is fixedly installed at both ends of the lower surface of the material receiving platform 2. A cam 302 is rotatably installed in the first fixed block 301. Both ends of the upper surface of the material receiving platform 2 are fixedly installed with a second fixed block 303. A push rod 305 is slidably installed in the second fixed block 303. A pulley 304 is rotatably installed at one end of the push rod 305. The pulley 304 is tightly fitted with the cam 302 to make the push rod 305 perform linear reciprocating motion.

A first screen 102 is fixedly installed at one end of the upper surface of the screening plate 1, a second screen 103 is fixedly installed in the middle of the upper surface of the screening plate 1, and a third screen 104 is fixedly installed at the other end of the upper surface of the screening plate 1. A first material trough 202 is opened at one end of the material receiving platform 2, a second material trough 203 is opened in the middle of the material receiving platform 2, and a third material trough 204 is opened at the other end of the material receiving platform 2. The screening plate 1 is inclined relative to the material receiving platform 2, the first screen 102 is higher than the second screen 103, the second screen 103 is higher than the third screen 104, the filter through hole of the first screen 102 is smaller than the filter through hole of the second screen 103, and the filter through hole of the second screen 103 is smaller than the filter through hole of the second screen 103. The hole is smaller than the filter hole of the third sieve 104, the first material trough 202 is set at the lower end of the first sieve 102, the second material trough 203 is set at the lower end of the second sieve 103, and the third material trough 204 is set at the lower end of the third sieve 104, which is used to collect nano raw materials of different sizes that fall through the sub-screening. At the same time, since the mesh diameters of the first sieve 102, the second sieve 103, and the third sieve 104 are successively larger, the particle size of the raw materials screened out by the entire screening device is different, and the free adjustment of the particle size is realized. At the same time, raw materials of multiple particle sizes can be screened out simultaneously on one screening device, thereby improving the screening efficiency.

The four corners of the lower end of the main frame 105 are fixedly installed with first fixed grooves 106, and springs 1061 are fixedly installed in the first fixed grooves 106. The four corners of the upper surface of the receiving platform 2 are fixedly installed with second fixed grooves 201, and the other end of the spring 1061 is fixedly installed in the second fixed groove 201. The other end of the top rod 305 is fixedly installed with a top plate 306, and the other end of the top plate 306 is fixedly connected to one side of the lower surface of the main frame 105. When the nano-raw material to be screened is placed on the screening plate 1, the spring 1061 is shortened. When the cam 302 rotates and the top plate 306 pushes the main frame 105 upward, the spring 1061 will release a certain elastic force to reduce the gravity on the cam 302, improve the vibration effect, and further improve the screening efficiency.

A plurality of screening-aiding strips 107 are arranged on the upper surface of the screening plate 1 to prevent the nano-raw materials from sliding downward under the action of their own gravity, causing some of the nano-raw materials to enter the second screen 103 or the third screen 104 without being screened by the first screen 102. The nano-raw materials are blocked by the plurality of drying-aiding strips 107 to ensure that the nano-raw materials pass through vibration screening and enter the next screen, thereby further improving the screening effect.

When the utility model is used in practice, the nano raw materials to be screened are placed on the discharge plate 101, and the cam 302 rotates, and the pulley 304 fitted with the cam 302 rotates along the edge of the cam 302, at which time the push rod 305 starts to make reciprocating linear motion, and the top plate 306 will drive the sub-screen plate 1 to start vibrating, and the nano raw materials start to move downward from the discharge plate 101, and the small nano raw materials filtered by the first screen 102 will fall into the first material trough 202 at the lower end, and the remaining nano raw materials slowly enter the second screen 103, and the larger nano raw materials will pass through the second screen 103 and fall into the second material trough 203 set at the lower end, and the remaining nano raw materials will pass through the third screen 104 and enter the third material trough 204, thereby performing multi-stage screening on nano raw materials of different sizes according to the sieve particle diameter.
