Description

Technical Field

[0001] The invention relates to the technical field of anti-blocking of vibrating screens, in particular to a vibrating screen with anti-blocking screen plates. Background Art

[0002] The vibrating screen works by using the reciprocating vibration generated by the vibrator excitation. The upper rotating weight of the vibrator causes the screen surface to produce a plane gyration vibration, while the lower rotating weight causes the screen surface to produce a conical gyration vibration. The combined effect causes the screen surface to produce a complex gyration vibration. Its vibration trajectory is a complex space curve. The curve is projected as a circle on the horizontal plane and an ellipse on the vertical plane. Adjusting the exciting force of the upper and lower rotating weights can change the amplitude, and adjusting the spatial phase angle of the upper and lower weights can change the curve shape of the screen surface motion trajectory and change the motion trajectory of the material on the screen surface.

[0003] Vibrating screen is a kind of screening machine widely used in coal and other industries for material classification, washing, dehydration and de-mediation. Among them, linear vibrating screen has been widely used due to its high production efficiency, good classification effect and convenient maintenance. During the working process, the dynamic performance of the vibrating screen directly affects the screening efficiency and service life. The vibrating screen uses the vibration motor excitation as the vibration source to make the material be thrown up on the screen and move forward in a straight line. The material enters the feed port of the screening machine evenly from the feeder, and passes through the multi-layer screen to produce several specifications of screened and screened materials, which are discharged from their respective outlets. The linear vibrating screen (linear screen) has the advantages of stability and reliability, low consumption, low noise, long life, stable vibration shape and high screening efficiency. It is a new type of efficient screening equipment, widely used in mining, coal, smelting, building materials, refractory materials, light industry, chemical industry and other industries. In the prior art, such as the Chinese patent number: CN217963476U "A kind of anti-clogging vibrating screen", includes a box body, a buffer spring is arranged at the bottom of the box body, the top of the buffer spring is fixedly connected to the four corners of the bottom of the box body and the bottom end of the buffer spring is fixedly connected to the supporting legs, a vibrator is arranged on one side of the bottom of the box body, a feed pipe is arranged on one side wall of the box body, a discharge port is opened on the other side wall of the box body, a screening mesh plate is arranged in the inner cavity of the box body, and a material guide platform is symmetrically arranged on both sides of the bottom of the inner cavity of the box body, a first cleaning component is arranged above the screening mesh plate, a second cleaning component is arranged below the screening mesh plate, and a discharge hopper is arranged below the box body. The beneficial effect is that by setting the feed pipe, the material can be introduced into the screening mesh plate in the box body through the feed hopper, by setting the vibrator, the material can be screened in cooperation with the screening mesh plate, and by setting the first cleaning component, a good cleaning ability can be provided for the screening mesh plate when it is blocked, thereby greatly avoiding the screening mesh plate from being blocked by the material, ensuring the screening effect and efficiency of the material, and the driven gear can be driven to rotate by driving the active gear, thereby simultaneously driving the articulated rods thereon to push the connecting plate, so that the connecting plate slides in the inner cavity of the driving box through the pulley, that is, the cleaning support plate and the cleaning plug on it are driven by the connecting rod to perform reciprocating longitudinal The cleaning rod can move in the direction of the screen mesh and clean the mesh on the screening mesh plate. The second cleaning component can provide a good cleaning ability when the screening mesh plate is blocked, thereby greatly avoiding the screening mesh plate from being blocked by materials and ensuring the screening effect and efficiency of the materials. By turning on the driving motor, the first gear can be driven to rotate through its output end, and the second gear and the transmission shaft can be driven to rotate through the chain. The transmission shaft can drive the cleaning brush thereon through the support rod to brush the screening mesh plate back and forth. By setting up a guide table, the screened material can be guided to the discharge hopper and finally discharged through the discharge pipe for subsequent processing.

[0004] However, in the prior art, in the above cases, the materials are directly introduced into the screening mesh plate. Since the materials pile up and fall down onto the screening mesh plate, it is easy to cause the mesh plate holes to be blocked or the material discharge is slow, which will affect the discharge efficiency.

Through the vibration of the material blocking frame 500, the adsorption range of the cleaning component 600 is increased, thereby protecting the safety of nearby staff, reducing the splashing of powder generated by material screening and being difficult to clean, and improving the scope of use of the equipment.

[0028] Working principle: When in use, the material is introduced into the guide frame 311 in the unloading mechanism 300, and the motor 321 is turned on first. The screened material first enters the upper guide trough 3111, and the motor 321 drives the rotating shaft 1 312 to rotate. The rotating shaft 1 312 drives the peripheral material dividing plate 313 to rotate in the upper guide trough 3111, so that the material falls into the lower guide trough 3112 in equal amounts. When the rotating shaft 1 312 rotates, the belt 324 drives the driven wheel 323 to rotate, so that the rotating shaft 2 314 of the inner circle of the driven wheel 323 drives the spiral blade 315 to further crush the large pieces of material. The rotation of the spiral blade 315 can prevent the material from directly accumulating and falling into the vibration frame 101 to cause blockage, so that the material screening process is smooth. Secondly, The materials will first fall onto the second sieve plate 402 in equal amounts, and smaller materials will fall onto the first sieve plate 401 through the second discharge hole 4021, and then smaller materials will fall into the bottom of the vibration frame 101 through the first discharge hole 4012 opened in the first sieve plate 401. Finally, the materials on the first sieve plate 401 will be vibrated to the lowest part of the groove on the first sieve plate 401 due to the vibration of the vibrator, and will be discharged from the equipment through the second discharge chute plate 4011, so that the materials falling into the vibration frame 101 will be moved to the lowest part of the vibration frame 101 through the vibration, and will be discharged from the equipment through the first discharge chute plate 1015. The equipment can quickly distinguish and store materials according to their size, thereby improving the practicability of the equipment, and the structure is simple and practical. By arranging a buffer mechanism 200 between the vibration frame 101 and the bottom plate 102, when the vibration frame 101 is shaken by the vibrator, the downward buffering pressure of the vibration frame 101 drives the multiple support rods 211 and the multiple top hinge seats 222 to float up and down, so that the multiple support rods 211 drive the movable plate 213 to slide in the buffer cylinder 212, and the buffer spring 1 214 can increase the buffering fluctuation, so that the multiple top hinge seats 222 drive the lower movable support rod 221 to move up and down in the opposite direction, so that the movable support rod 221 drives the slider 223 to slide in the movable groove 1021 through the bottom hinge seat 222, and then the elastic force of the buffer spring 224 between the two sliders 223 increases the fluctuation, and the buffering of the vibration frame 101 is increased through the buffer mechanism 200, while reducing the vibration driven by the vibrator. The frame 101 vibrates to avoid damage to the equipment and improve its service life; by rotating the insertion rods 403 at the four corners of the vibration frame 101, the positions of the insertion rods 403 and the fixed blocks 404 thereon correspond to the pull blocks 4024, and the second sieve plate 402 will fall to the top of the first sieve plate 401, so that the multiple cleaning rods 4022 at the bottom of the second sieve plate 402 are inserted into the multiple first discharge holes 4012 opened in the first sieve plate 401, and the inner circle of the first discharge holes 4012 on the first sieve plate 401 can be cleaned, which is convenient for cleaning and reduces manual labor. The insertion rods 403 at the four corners of the vibration frame 101 can also be removed, so that the second sieve plate 402 and the first sieve plate 401 can be taken out from the inside of the vibration frame 101, and different sieve plates can be replaced according to the size of the material to be screened, thereby avoiding clogging of the sieve plate holes and lowering the screening efficiency.
