The combined vibrating wind screen 5 includes a vibrating screen box and a separating screen 506 arranged on the vibrating screen box. The vibrating screen box includes a housing 504, and a layer of sieve plates 514 arranged up and down in the housing 504 and the second-layer sieve plate 516, the material inlet 501 is arranged at one end of the housing 504, and the other end of the housing 504 is provided with a finished product discharge pipe 520, and the specific gravity screening device 6 is arranged below the finished product discharge pipe 520 and is connected with the finished product discharge pipe 520. The pipe 520 is connected, and the separating screen 506 is connected with the finished product discharge pipe 520 .

The feed port 501 of the vibrating screen box is arranged at one end of the housing 504, a large miscellaneous outlet pipe 511 for discharging impurities on the first layer of sieve plate 514 is provided on the first layer of sieve plate 514, and a useful pipe is provided on the second layer of sieve plate 516. The finished product discharge pipe 520 that discharges the material on the second-layer sieve plate 516, the material inlet 501 is connected with the discharge port of the hoist 2, the spiral dust collector 3 is connected with the separating screen 506, and the specific gravity screening device 6 is connected with the The lower end of the finished product discharge pipe 520 is connected. The integrated design of the screen box and the air screen reduces the overall size of the components, reduces the weight of the whole machine, and at the same time increases the integrity of the whole machine and reduces the damage rate.

The separation screen 506 includes a separation screen plate arranged in steps and a miscellaneous intake port 507 arranged above the high end of the separation screen plate. An arch plate is arranged above the separation screen plate. The feed port of the separation screen 506 is connected with the finished product The discharge pipe 520 is connected. The separation sieve plate includes a first sieve plate 509 and a second sieve plate 5010 and a connecting sieve plate arranged between the first sieve plate 509 and the second sieve plate 510 . The arch plates include a first arch plate 518 and a second arch plate 519 corresponding to the first sieve plate 509 and the second sieve plate 510 .

The separation sieve adopts a step-by-step suction method for winnowing, and the material repeatedly absorbs impurities in layers between the first sieve plate and the second sieve plate. The winnowing effect is good and the production efficiency is high.

A bulk grain box 4 is arranged between the discharge port of the elevator 2 and the feed port 501 of the combined vibrating wind screen.

The feeding end of the combined vibrating wind screen 5 is connected with a rear air suction port 9 , and the rear air suction port 9 is in communication with the spiral dust collector 3 . Before the material falls into the sieve plate, the pre-air separation is carried out to remove some of the lighter impurities in the material, reducing the screening pressure of the sieve plate, and the screening effect is better and the efficiency is high.

Vibration motors 505 are arranged symmetrically on both sides of the casing 504 of the utility model. Due to the simple structure and light weight, the whole device only needs two vibration motors 505 with a power of about 0.37kW to realize the vibration work. However, the motor power of the original winnowing device and the independent design of the screening needs 3kW, which greatly reduces the power consumption of the whole machine.

When in use, the material enters the combined vibrating air selection screen 5 through the discharge port of the hoist 2, passes through the bulk grain box 4, and falls to a layer of sieve plate 514. The large miscellaneous discharge pipe 511 is discharged, and the remaining materials fall into the second-layer sieve plate 516, and the small impurities fall after being screened. The material after removing large impurities and small impurities moves forward to the separating screen 506 for further screening with vibration. Multi-stage screening is carried out before entering the separation screen 506 for air selection. The air screen and screening device are designed in one piece, and the air selection and screening are completed at one time. There is no need to set up a separate screening device, which saves space. After the materials are screened, they enter the separation screen 506 for air selection, which reduces the separation pressure of the separation screen 506, and the screening effect is better. At the same time, the integrated design and stable structure will also reduce the damage rate of equipment and reduce maintenance costs. After the material enters the separating screen 506, the material remaining on the second-layer sieve plate 516 after removing large and small impurities is thrown out by the sieve plate at the discharge end, and then discharged from the finished product discharge pipe 520. Due to the effect of wind force, the particles are light and The light impurities are sucked into the separation screen 506, and enter the first sieve plate 509 and the second sieve plate 510 step by step. Due to the wind force and vibration, the materials will be layered according to the specific gravity of the particles. The light materials float on the upper layer, and the heavier materials The first arch 518 and the second arch 519 play the role of guiding the wind direction and controlling the wind speed. The inner space of the first arch 518 and the second arch 519 gradually increases, and the wind speed also gradually decreases. Small and heavy materials inhaled fall to the corresponding sieve plates, and the sieve plates at all levels transport them to the discharge end again from the finished product discharge pipe 520 and enter the next process. discharge. The materials are repeatedly screened in the cover plates at all levels, and the materials after winnowing have high purity, and at the same time, good materials are prevented from being discharged by mistake, and the production efficiency is improved. The material discharged from the finished product discharge pipe 520 falls into the specific gravity screening device 6 for further screening, and the screened material is bagged through the material receiving port 7 .

The discharge end mentioned in this application is the end opposite to the feed inlet 501 in the casing 504 .

The utility model integrates the design of the wind screen and the screening device, and the whole machine does not need to be installed with a screening device during use, which effectively reduces the volume of the whole machine. failure rate.
