Description

Technical Field

[0001] The present application relates to the technical field of vibrating screens, and in particular to a mineral material blocking-proof vibrating screen. Background Art

[0002] A vibrating screen is a type of screening equipment that utilizes reciprocating vibrations generated by a vibrator. Its operating principle is that the material is thrown onto the screen surface through the vibrations of a vibrating motor, simultaneously moving forward in a linear motion. Screening is achieved through the use of a properly matched screen mesh. The vibration path of a vibrating screen is complex, but can generally be described as a spatial curve that projects as a circle on a horizontal plane and an ellipse on a vertical plane.

[0003] Chinese patent number CN219424870U discloses an anti-blocking vibrating screen, comprising: a screen box; a plurality of sliding rods, each of which is vertically fixedly mounted around the top of the screen box; a plurality of springs, each of which is slidably mounted on the plurality of sliding rods; a plurality of limit blocks, each of which is fixedly mounted on the top of the plurality of sliding rods; a screen bucket, each of which has an extension portion at the top, each of which has a plurality of through holes around the extension portion, each of which is mounted on the plurality of sliding rods; a plurality of vibration motors, each of which is fixedly mounted on the bottom of the portion of the extension portion extending outside the sliding rods; a screen mesh, each of which is arranged at the bottom of the screen bucket; and two anti-blocking mechanisms, each of which is symmetrically arranged on the inner wall of the screen box for striking the screen mesh. This utility model has the advantages of high screening efficiency, anti-blocking function, and convenient operation.

[0004] However, in the process of conceiving and realizing the above application, the inventors found that in actual use of the above technical solution, since the metal ball is made of rigid material, the rigid impact generated when the metal ball hits the bottom of the screen causes great damage to it, thereby resulting in the screen being replaced too frequently. Utility Model Content

[0005] In order to solve or partially solve the problems existing in the related art, the present application provides a mineral material anti-blocking vibrating screen.

[0006] To achieve the above objectives, this application is implemented through the following technical solutions:

[0007] A mineral material anti-blocking vibrating screen comprises a screen box, a support is provided at the bottom of the screen box, a screen bucket is provided at the top of the screen box, and a vibration motor is provided on two extensions of the screen bucket. The mineral material anti-blocking vibrating screen further comprises:

[0008] A first screen and a second screen are arranged in parallel in the screen bucket, the second screen is fixed to the bottom of the screen bucket, and the first screen is adjustably installed above the second screen by adjusting bolts;

[0009] A plurality of rubber elastic balls are placed on the second screen, and the diameter of the rubber elastic balls is larger than the diameter of the screen holes of the first screen and the second screen.

[0010] Optionally, a chute matching the end of the first screen is provided on the side wall of the sieve bucket, a waist hole allowing an adjusting bolt to pass through is provided on the side of the chute, and a screw hole matching the adjusting bolt is provided on the end of the first screen;

[0011] The first screen is moved up and down in the chute by loosening the adjusting bolt, and the position of the first screen is fixed by tightening the adjusting bolt.

[0012] Optionally, a slide rod is provided on the two extension parts of the screen bucket, the upper end of the slide rod passes through the extension part and is connected to the limit block, and the lower end of the slide rod is fixed to the top of the screen box.

[0013] Optionally, a spring is sleeved on the sliding rod.

[0014] Optionally, the mesh diameter of the first sieve is larger than the mesh diameter of the second sieve.

[0015] Optionally, the vibration motor is mounted on the lower end surfaces of the two extensions and is located on one side of the sliding rod.

[0016] Optionally, a collecting hopper is provided at the bottom of the screen box, and the collecting hopper is in the shape of a funnel that is wide at the top and narrow at the bottom.

[0017] Optionally, the support is fixed to the ground by anchor bolts.

[0018] Beneficial effects of the present application: The present application utilizes a rubber elastic ball to impact the screen to prevent it from clogging. The rubber elastic ball is made of a flexible rubber material with good elasticity and softness. When the rubber elastic ball impacts the screen, its elasticity can absorb and disperse the impact energy, reducing the direct effect of the energy on the screen. Moreover, the rubber elastic ball will deform when impacted, but then quickly return to its original shape. This rapid deformation recovery ability helps to reduce the sustained pressure and damage caused by the impact on the screen. At the same time, due to the elasticity of the rubber elastic ball, the impact energy is dispersed over a larger area when it contacts the screen, thereby reducing the energy density per unit area. This energy dispersion effect helps to reduce local damage to the screen. In addition, the softness and elasticity of the rubber elastic ball can also buffer the impact force to a certain extent, so that the impact force does not reach a peak instantly, but is gradually released. This buffering effect helps protect the screen from sudden impact damage. In this way, by replacing the metal ball with a rubber elastic ball, the damage to the screen caused by the impact force is reduced, thereby reducing the frequency of screen replacement.

[0032] The above description is merely an optional embodiment of the present application and is not intended to limit the present application.

[0033] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings to facilitate understanding by technical personnel.

[0034] Example 1:

[0035] See also Figures 1 to 3 A mineral material anti-blocking vibrating screen includes a screen box 1, a support 2 is provided at the bottom of the screen box 1, a screen bucket 3 is provided at the top of the screen box 1, and vibration motors 4 are provided on two extensions of the screen bucket 3. The mineral material anti-blocking vibrating screen also includes:

[0036] A first screen 5 and a second screen 6 are arranged in parallel in the screen bucket 3, the second screen 6 is fixed to the bottom of the screen bucket 3, and the first screen 5 is adjustably mounted above the second screen 6 by an adjusting bolt 7;

[0037] A plurality of rubber elastic balls 8 are placed on the second screen 6 , and the diameter of the rubber elastic balls 8 is larger than the diameter of the sieve holes of the first screen 5 and the second screen 6 .

[0038] Specifically, the second screen 6 is fixed to the bottom of the sieve bucket 3, and the first screen 5 is adjustably mounted above the second screen 6 via an adjusting bolt 7. When the adjusting bolt 7 is loosened, the first screen 5 can move within the sieve bucket 3. In this way, by changing the installation position of the first screen 5 within the sieve bucket 3, the distance between the first screen 5 and the second screen 6 can be adjusted, thereby limiting the jumping amplitude of the rubber elastic ball 8 and thus changing the elastic force. When the elastic force is appropriate, the position of the first screen 5 can be fixed by tightening the adjusting bolt 7. The diameter of the rubber elastic ball 8 is larger than the sieve hole diameters of the first screen 5 and the second screen 6 to prevent the rubber elastic ball 8 from falling.

[0039] During operation, the spacing between the first and second screens 5, 6 is adjusted by adjusting bolts 7 to ensure the appropriate elastic force of the rubber ball 8. The vibration motor 4 is then activated, causing the screen hopper 3 to vibrate, which in turn causes the first and second screens 5, 6 to vibrate synchronously. The vibration of the first screen 5 provides a preliminary screening of the material, while the vibration of the second screen 6 provides a secondary screening. This two-stage screening process results in different grades of material. This function is crucial for subsequent processing, ensuring that the material meets specific particle size requirements.

[0040] In this embodiment, since the rubber elastic ball 8 has its own elasticity and weight, during the vibration of the screen bucket 3, it will drive the rubber elastic ball 8 to bounce repeatedly between the first screen 5 and the second screen 6, thereby hitting the first screen 5 and the second screen 6, thereby removing the material residue on the screen and preventing the screen from being blocked.

[0041] In conventional technology, a metal ball is used to impact the screen to prevent it from clogging. However, since the metal ball is made of a rigid material, it will produce a rigid impact when hitting the bottom of the screen. This rigid impact will cause significant damage to the screen, resulting in the screen being replaced too frequently. In this embodiment, a rubber elastic ball 8 is used to impact the screen to prevent it from clogging. The rubber elastic ball 8 is made of a flexible rubber material, which has good elasticity and softness. When the rubber elastic ball 8 impacts the screen, its elasticity can absorb and disperse the impact energy, reducing the direct effect of the energy on the screen. Moreover, the rubber elastic ball 8 will deform when impacted, but will then quickly return to its original shape. This rapid deformation recovery ability helps to reduce the continuous pressure and damage caused by the impact on the screen. At the same time, due to the elasticity of the rubber elastic ball 8, the impact energy will be dispersed over a larger area when it contacts the screen, thereby reducing the energy density per unit area. This energy dispersion effect helps to reduce local damage to the screen. In addition, the softness and elasticity of the rubber elastic ball 8 can also cushion the impact force to a certain extent, so that the impact force does not reach a peak instantly, but is gradually released. This cushioning effect helps protect the screen from sudden impact damage. In this way, by replacing the metal ball with the rubber elastic ball 8, the damage to the screen caused by the impact force is reduced, thereby reducing the frequency of screen replacement.

[0044] The first screen 5 is moved up and down in the chute by loosening the adjusting bolt 7, and the position of the first screen 5 is fixed by tightening the adjusting bolt 7.

[0045] Specifically, the waist hole 9 is connected to the chute, and the threaded end of the adjusting bolt 7 enters the chute through the waist hole 9 and is threadedly connected with the screw hole on the first screen 5. When the adjusting bolt 7 is tightened, the position of the first screen 5 is fixed;

[0046] When the distance between the first screen 5 and the second screen 6 needs to be adjusted, loosen the adjusting bolt 7 to drive the first screen 5 to slide up and down in the slide groove. When the first screen 5 moves to a suitable height, tighten the adjusting bolt 7 to the screw hole position corresponding to the waist hole 9 and the first screen 5 to fix the first screen 5.

[0047] In addition, in order to facilitate the installation and adjustment of the first screen 5, the screen box 1, the screen bucket 3, the first screen 5 and the second screen 6 can be set to be square.

[0052] Optionally, the mesh diameter of the first sieve 5 is larger than the mesh diameter of the second sieve 6 .

[0054] Optionally, the vibration motor 4 is mounted on the lower end surfaces of the two extensions and is located on one side of the slide bar 10 .

[0056] Optionally, a collecting hopper 13 is provided at the bottom of the screen box 1, and the collecting hopper 13 is in the shape of a funnel that is wide at the top and narrow at the bottom.

[0057] Specifically, the screened mineral material is collected by the collecting hopper 13 and discharged through the discharge port at the bottom of the collecting hopper 13; the collecting hopper 13 adopts a funnel shape that is wide at the top and narrow at the bottom, which facilitates the mineral material to slide along the inclined inner wall of the collecting hopper 13 and gather at the bottom.

[0058] Optionally, the support 2 is fixed to the ground by anchor bolts.
