Abstract
The utility model discloses a dynamic sealing device of a vibrating screen, and aims at designing a dynamic sealing device of a vibrating screen, with good sealing effect and reasonable structure. The dynamic sealing device adopts the technical scheme that the dynamic sealing device comprises a main shaft; the main shaft penetrates through the interior of a casing; a static pressing piece is arranged in a main shaft hole of the casing; a dynamic pressing piece is in frictional contact with the static pressing piece; the dynamic pressing piece is connected with an adjusting frame through a spring; and the dynamic pressing piece is mounted on the main shaft in a sleeving manner. The dynamic sealing device has a reasonable structure, can effectively guarantee the sealing of the vibrating screen, efficiently improves the poor sealing effect at the shaft hole part in the prior art, and does not pollute the environment.
Description
Technical field:
The utility model relates to vibrating sieve, particularly a kind of vibrating sieve dynamic sealing means to the vibrating sieve good sealing effect.
Background technique:
The vibrating mechanical equipment that uses in industries such as coal, metallurgy, mines now, owing to easily produce a large amount of airborne dusts in the material screening process, if encapsulation process is bad, can the severe contamination working environment.And the natural vibration characteristic of the Large Amplitude Vibration of vibrating machine makes the sealing technique difficulty between its fixed block very large, and sealing effect is relatively poor.
Summary of the invention:
The purpose of this utility model is a kind of sealing effect of design vibrating sieve dynamic sealing means better, rational in infrastructure.
The technical solution of the utility model is, a kind of vibrating sieve dynamic sealing means, it comprises main shaft, it is characterized in that: main shaft is through in the casing, the spindle hole of main place of casing is provided with the static pressure sheet, with static pressure sheet rubbing contact the dynamic pressure sheet arranged, the dynamic pressure sheet links to each other with adjusting frame by spring, the dynamic pressure sheet is sleeved on the main shaft.
The utility model is rational in infrastructure, can effectively guarantee the sealing of vibrating sieve, and the poorly sealed situation of former axis hole part is effectively improved, and is free from environmental pollution.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Describe by reference to the accompanying drawings embodiment in detail, specific embodiment of the utility model is, a kind of vibrating sieve dynamic sealing means, it comprises main shaft 5, main shaft is through in the casing 4, and spindle hole of main 7 places of casing are provided with the static pressure sheet 3 of ring-type, with static pressure sheet rubbing contact be provided with dynamic pressure sheet 6, the dynamic pressure sheet links to each other with adjusting frame 1 by spring 2, and the dynamic pressure sheet is sleeved on the main shaft.Described structure of the present utility model, make main shaft when vibration, be sleeved on the also thereupon shake of dynamic pressure sheet on the main shaft, and dynamic pressure sheet and static pressure sheet rubbing contact, can not produce the slit, guarantee the sealing effect at spindle hole of main place, effectively reduced the vibrating sieve of knowing clearly easily leaks material, the dust that leaks from sieve aperture situation, be of value to the improvement of production environment.
