Abstract
The invention discloses a secondary damping system of a linear vibrating screen, and relates to the field of vibrating screens for coal mines. The secondary damping system of the linear vibrating screen comprises a vibrating screen body, and further comprises a primary damping spring and damping girders, wherein a fixing seat and a base support the bottom of the vibrating screen body; onedamping girder is fixed to the top of the primary damping spring; and the bottom of the primary damping spring is arranged at the top of the vibrating screen body. According to the secondary damping system provided by the invention, after secondary damping, the dynamic load of the linear vibrating screen to the ground is only 1/5 of the dynamic load of an original structure to the ground, the impact of a screening machine to the ground is relieved, the screen is steadier during the operation process, the noise is greatly reduced, and the maintenance rate is reduced; and besides, the resonance caused by the situation that the inherent frequency of a building is close to the inherent frequency of the screening machine is removed through the secondary damping design, and the damage of the screen to a factory building is effectively reduced.
Description
Technical field
The present invention relates to coal vibration screen for mineral field, specifically, the present invention relates to a kind of straight line reciprocating sieve secondary shock-absorbing system.
Background technology
Linear vibrating screen utilizes vibrating motor exciting as vibration source, make material tossed on screen cloth, simultaneously for linear motion forward, material is from the batcher charging aperture evenly into screening machine, produce the oversize of several specifications, siftage by multilayer screen cloth, discharge from respective outlet respectively, have power consumption low, yield is high, simple in construction, easy-maintaining, full-closed structure, overflow without dust and dissipate, automatic discharge, it is more suitable for assembly line work, coal preparation plant's coal separation process applies to straight line reciprocating sieve in a large number.
The product de-media sieve that coal preparation plant now uses installs the linear vibrating screen of layout concentratedly for flood, lasting increase with plant area's raw coal washing amount, linear vibrating screen in use manifests that sieve nest operational shock is big, noise is big gradually, sieve nest basis floor resonant conditions is serious, sieve nest surrounding base damages frequently, affects normal washing to a certain extent and produces.
Summary of the invention
The technical problem to be solved is to provide a kind of shock mitigation system applying to reciprocating sieve, and this shock mitigation system can alleviate sieve nest resonance.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is: a kind of straight line reciprocating sieve secondary shock-absorbing system, including shaker body, described reciprocating sieve body bottom portion is by fixing seat and base offer support, also include one-level damping spring and damping crossbeam, described damping crossbeam is fixed on one-level damping spring top, is arranged on the top of shaker body bottom one-level damping spring.
Preferably, described one-level damping spring top is provided with two grades of damping springs, and two grades of damping spring tops arrange damping crossbeam equally.
Preferably, described one-level damping spring and two grades of damping springs are rubber spring.
Preferably, described fixing seat is cased with buffer spring.
Adopt technical scheme, following beneficial effect can be obtained:
The secondary shock-absorbing system of the present invention, the dynamic loading on ground is just corresponded to original structure 1/5 to ground dynamic loading by linear vibrating screen after secondary vibration damping, alleviates the screen(ing) machine impact to ground, and sieve is more steady in running, noise is greatly reduced, and then reduces maintenance rate.It addition, the resonance that the natural frequency of the secondary Vibration Absorption Designing natural frequency and screen(ing) machine that also eliminate building causes when being close, can effectively reduce the sieve damage to Factory Building.
Accompanying drawing explanation
Below the content expressed by each accompanying drawing of this specification and the labelling in figure are made brief description:
Fig. 1 is the structural representation of linear vibrating screen;
Fig. 2 is one-level damping spring and the structural representation of two grades of damping springs;
Labelling in above-mentioned figure is: 1, shaker body; 11, fixing seat; 12, buffer spring; 13, base; 2, one-level damping spring; 3, two grades of damping springs; 4, damping crossbeam.
Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, the effect and operation principle etc. of the mutual alignment between the such as involved shape of each component of the specific embodiment of the present invention, structure, each several part and annexation, each several part is described in further detail.
As shown in Figure 1, 2, a kind of straight line reciprocating sieve secondary shock-absorbing system, including shaker body 1, support is provided by fixing seat 11 and base 13 bottom reciprocating sieve body 1, also include one-level damping spring 2 and damping crossbeam 4, damping crossbeam 4 is fixed on the top of one-level damping spring 2, is arranged on the top of shaker body 1 bottom one-level damping spring 2.
As in figure 2 it is shown, one-level damping spring 2 top is provided with two grades of damping springs 3, two grades of damping spring 3 tops arrange damping crossbeam 4 equally; One-level damping spring 2 and two grades of damping springs 3 are rubber spring, and rubber spring is originally as quality of rubber materials, and the spring shock absorption of quality of rubber materials is effective and the damage of shaker body 1 sieve nest is little; Being cased with buffer spring 12 on fixing seat 11, the spring body body of buffer spring 12 is harder, it is possible to tolerate bigger impulsive force, it is prevented that produce to impact to vibration screen body.
During use, one-level damping spring 2 as shown in Figure 2 and two grades of damping springs 3 are linked together, damping crossbeam 4 on two grades of damping springs 3 is fixed on the fixing post on reciprocating sieve side, one-level damping spring 2 and two grades of damping springs 3 are fixed on the top of reciprocating sieve body 1 as shown in Figure 1, during reciprocating sieve body 1 operation vibration, two-stage damping device thereon can absorb the vibrations that reciprocating sieve body 1 produces, simultaneous buffering spring 12 can also reduce the resonance of sieve nest, reduces the sieve nest damage to Factory Building.
The secondary shock-absorbing system of the present invention, the dynamic loading on ground is just corresponded to original structure 1/5 to ground dynamic loading by linear vibrating screen after secondary vibration damping, alleviates the screen(ing) machine impact to ground, and sieve is more steady in running, noise is greatly reduced, and then reduces maintenance rate. It addition, the resonance that the natural frequency of the secondary Vibration Absorption Designing natural frequency and screen(ing) machine that also eliminate building causes when being close, can effectively reduce the sieve damage to Factory Building.
Above in conjunction with accompanying drawing, the present invention is exemplarily described; the obvious present invention implements and is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that the design of the method for the present invention carries out with technical scheme; or the not improved design by the present invention and technical scheme directly apply to other occasion, all within protection scope of the present invention.
