DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0027] As shown in Figures 1-2 , Figure 5 the present embodiment provides a novel circular vibrating screen, which mainly comprises a screen 1 and a circular vibrating screen main body 2. The circular vibrating screen main body 2 has a mounting frame 21 for mounting the screen 1. The circular vibrating screen main body 2 is vibrated by a vibrator with eccentric mass driven by a driving motor, so as to transmit the vibration force to the screen 1 located on the mounting frame 21, so that the material located on the screen 1 is screened by the vibration force.
[0028] The mounting frame 21 comprises a plurality of mounting strips 211, and each mounting strip 211 is uniformly distributed symmetrically with the screen 1 as the center, that is, there are mounting strips 211 for mounting the screen 1 on both sides of the screen 1, so that there are support force points on both sides of the screen 1, which helps to ensure the stability of the screen 1 when it is under stress, so that it can work under stable posture and evenly disperse the force.
[0029] Because the material passes through the screen, and the circular vibrating screen body 2 transmits the vibration force to the screen 1, the screen 1 will displace during the vibration, which may directly collide with the mounting frame 21 (the mounting strip 211), and the direct collision will generate a large impact force, affecting the stability of the equipment and causing damage to the screen itself. Therefore, the screen 1 in the embodiment is provided with a buffer strip 3 between each mounting strip 211, which is preferably made of a long-service-life elastic material such as rubber, to ensure the service life of the buffer strip 3. After the buffer strip is installed, the elastic contact between the screen 1 and the buffer strip 3 reduces the hard contact between the screen 1 and the mounting frame 21, and reduces the transmission of the impact force; and the buffer strip 3 can absorb part of the kinetic energy during the vibration according to the elasticity and deformation capacity of the material, which is converted into heat energy or dissipated in other forms. In this way, the amplitude and intensity of the vibration are significantly reduced, avoiding damage to the screen 1 caused by excessive mechanical impact, and improving the service life of the screen 1.
[0030] The buffer strip 3 is provided with a mounting groove 31 for embedding the screen 1, so that the projection surface of the buffer strip 3 in the axial direction can present a "U" shaped structure, so that the buffer strip 3 can play a buffering role consistent with the vibration direction (both sides of the screen 1) of the screen 1 embedded in the buffer strip 3, so that the buffer strip 3 has a more comprehensive buffering range for the screen 1.
[0031] Preferably, the buffer strip 3 should be detachably connected with the mounting strip 211, specifically, by limiting the movement of the buffer strip 3 in the axial direction through two limiting mounting blocks fixed on the mounting strip 211 by bolts, and cooperating with the screen 1 embedded in the buffer strip 3 to constrain the buffer strip 3 itself, so as to finally realize the installation of the buffer strip 3 on the mounting strip 211.
[0032] Preferably, the projection surface of the mounting strip 211 in the axial direction is a horizontally placed "U" shaped structure, that is, the mounting strip 211 has a mounting opening for embedding and installing the buffer strip 3, so that the buffer strip 3 has stress points in both vibration directions of the screen 1, so as to deform the buffer strip 3 and absorb the impact force.
[0033] At the same time, the circular vibrating screen body 2 and the screen 1 are provided with a buffer structure 4 for damping the screen 1, which cooperates with the damping and buffering effect of the buffer strip 3 on the screen 1 to realize multiple buffering, further prolonging and improving the service life of the screen 1.
[0034] Specifically, as shown in Figures 3-4As shown, the buffer structure 4 in this embodiment mainly includes several support beams 41, several contact buffers 42, and several elastic elements 43. Each elastic element 43 is located one-to-one between each support beam 41 and contact buffer 42, and both ends of the elastic element 43 are fixedly connected to the support beam 41 and the contact buffer 42, respectively. In this embodiment, each elastic element 43 is preferably a compression spring. That is, when an external force (the force transmitted along the screen 1 to the contact buffer 42) acts on the elastic element 43, the elastic element 43 will undergo elastic deformation, converting the kinetic energy of the external force into elastic energy for storage. This deformation makes the compression or stretching process of the external force acting on the elastic element 43 more uniform, thereby playing a buffering role. The support beams 41 are fixedly installed inside the circular vibrating screen body 2, thereby ensuring that the buffer structure 4 will not be displaced during the buffering process, ensuring the stability of its buffering effect.
[0035] The screen 1 includes several screening sections 11 and several force-bearing sections 12. Each contact buffer 42 abuts against each force-bearing section 12. Each force-bearing section 12 is a flat plate structure, which effectively ensures the contact area between the contact buffer 42 and the force-bearing section 12, so that the contact buffer 42 can better apply the buffering force to the screen 1. Each screening section 11 is located between each adjacent force-bearing section 12, so that there are buffer force-bearing points on both sides of each screening point of the screen 1, thereby effectively reducing the impact force of the screen 1 when screening materials.
[0036] like Figures 3-4 As shown, each support beam 41 in this embodiment is provided with a mounting hole 411, and each elastic element 43 is located in each mounting hole 411. Thus, when the distance between the support beam 41 and the screen 1 is consistent, the elastic element 43 in this embodiment has a longer deformation stroke, which can be compressed more, thereby absorbing more energy and providing a better buffering effect. Moreover, the existence of the mounting hole 411 can constrain the deformation direction of the spring to a certain extent, ensuring that the deformation direction of the elastic element 43 is consistent with the force direction, thereby ensuring its buffering performance.
[0037] Because the screen 1 and the circular vibrating screen body 2 are inclined to facilitate the flow and movement of materials, the support beam 41 is also inclined, and therefore the opening of the mounting hole 411 on the support beam 41 is also inclined. To prevent the contact buffer 42 from being unable to be constrained by the mounting hole 411, causing it to easily move in the radial direction of the mounting hole 411, each contact buffer 42 is provided with a limiting ring 421 close to one end of the mounting hole 411, and the elastic element 43 is located in the inner ring of the limiting ring 421. The limiting ring 421 not only restricts the movement of the contact buffer 42, but also avoids occupying the internal space of the mounting hole 411 to affect the axial length of the elastic element 43, achieving two goals at once. At the same time, each mounting hole 411 is provided with a cooperating ring groove 412 away from the limiting ring 421, which avoids the influence of the limiting ring 421 on the downward stroke of the contact buffer 42, thereby ensuring the triggering effect of the contact buffer 42 on the elastic element 43 (the buffering effect of the buffering structure 4).
[0038] Each support beam 41 is provided with a plurality of contact buffers 42, which are arranged in a linear direction in sequence, that is, by providing a plurality of buffering structures 4, the buffering performance of the screen 1 in this embodiment is further improved.
[0039] The contact buffer 42 includes a connecting block 422 and a contact block 423, the connecting block 422 is located between the contact block 423 and the elastic element 43, and the connecting block 422 is fixedly connected with the elastic element 43. The contact block 423 is preferably made of elastic material such as rubber, that is, the contact block 423 itself has a certain buffering capacity, which cooperates with the deformation buffering of the elastic element 43 to further improve the buffering performance of this embodiment. The contact block 423 and the connecting block 422 are detachably connected, so that the contact block 423 can be replaced when it is damaged.
[0040] Specifically, a fixing element 5 is arranged between the connecting block 422 and the contact block 423, the fixing element 5 abuts against the contact block 423 and is threadedly connected with the connecting block 422, which not only ensures the connection strength, but also facilitates the disassembly of the fixing element 5. The contact block 423 is provided with a connecting hole 4231 for abutting the fixing element 5, the longitudinal section of the connecting hole 4231 is in the shape of a "T", and the fixing element 5 is preferably a bolt with a nut, so that the nut part cooperates with the connecting block 422 to complete the abutting and clamping of the contact block 423, thereby ensuring the connection strength of the contact block 423 and the connecting block 422. The end of the connecting hole 4231 away from the connecting block 422 is spaced apart from the fixing element 5, so as to avoid the contact between the fixing element 5 and the screen 1 during the vibration of the screen 1, thereby avoiding the impact phenomenon and the damage to each other.
[0041] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
