Description
Technical field
The utility model relates to screening plant, especially at the screening plant of food.
Background technology
Existing vibratory sieve generally is to be made of the screen cloth that has different apertures, the vibration power plant that drives the screen cloth vibration, the vibrating spring mechanism that is arranged between screen cloth and frame, and the vibration frequency of screen cloth is determined in interior whole system by the involving vibrations spring mechanism.In the process of using, generally be by changing the vibration frequency that vibrating spring mechanism regulates shaking screen, to reach the requirement of food screening.The weak point that exists is:
(1) vibration frequency of vibratory sieve is to realize by changing vibrating spring mechanism, and vibrating spring mechanism is anchored on screen cloth and the frame, changes to get up to waste time and energy, and brings great inconvenience to operation;
(2) vibrating spring mechanism is a kind of mechanical oscillation post of contact, is easy to generate very big noise pollution in the process of operation.
Therefore, it is that the vibrating mechanism that vibrating spring mechanism replaces to permanent magnet is realized contactless vibration column that a kind of improved vibratory sieve is arranged, it is to realize by non-magnetic conduction sleeve, non-conducting magnetic column and 2 identical polar permanent magnet opposed, utilize the mutual repulsive force of 2 permanent magnets to realize contactless support force, replace the function of spring.Then, when needs change the vibration frequency of vibration column and Oscillation Amplitude, just need to change the permanent magnet of different magnetic force, rather inconvenience in the operation.
The utility model content
Therefore, the utility model is at the weak point of above-mentioned vibratory sieve, proposes a kind of vibration frequency that can the quick adjustment vibration column, and the contactless shaking screen device that can avoid noise pollution in operating process.
The technical solution of the utility model is:
A kind of contactless shaking screen device comprises: screen cloth, be arranged on the screen cloth vibration power plant that drives its vibration, and be arranged on the frame and the vibration column of mesh support screen.Improvements are: described vibration column comprises: non-magnetic conduction sleeve, non-magnetic conduction guide pillar, non-flux sleeve jacket casing is on non-magnetic conduction guide pillar, non-magnetic conduction sleeve is arranged under the screen cloth, non-magnetic conduction guide pillar is arranged on the frame, and be arranged at first electromagnet that is positioned in the non-magnetic conduction sleeve under the screen cloth and be arranged at non-magnetic conduction sleeve and be positioned at second electromagnet on the non-magnetic conduction guide pillar, described first electromagnet and the second electromagnet homopolarity are oppositely arranged, on described screen cloth, also be provided with control circuit board, control circuit board electrically connects described first electromagnet and second electromagnet by electric wire, realizes the change of the magnetic force of first electromagnet and second electromagnet.
The utility model adopts technical scheme as above, can be used in food is screened, and the advantage that has is:
(1) control the magnetic force of electromagnet by the electric current of regulating control circuit board, and then regulate the change that 2 spacings between the electromagnet realize vibration frequency, easy to operate, time saving and energy saving, can satisfy the requirement of various food screenings;
(2) 2 electromagnet are arranged in the non-magnetic conduction sleeve respectively and on the non-magnetic conduction guide pillar, are a kind of contactless vibration columns, can effectively avoid the noise pollution problem that produces in the operating process.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
Now with the specific embodiment the utility model is further specified in conjunction with the accompanying drawings.
Consult shown in Figure 1ly, the contactless shaking screen device of present embodiment comprises: screen cloth 1, be arranged at the vibration power plant 2 that drives its vibration on the screen cloth 1, and be arranged on the frame 3 and the vibration column 4 of mesh support screen 1.Described vibration column 4 comprises: non-magnetic conduction sleeve 401, non-magnetic conduction guide pillar 402, non-magnetic conduction sleeve 401 is placed on the non-magnetic conduction guide pillar 402, non-magnetic conduction sleeve 401 is arranged at screen cloth 1 time, non-magnetic conduction guide pillar 402 is arranged on the frame 3, and be arranged to be positioned at first electromagnet 4031 under the screen cloth 1 in the non-magnetic conduction sleeve 401 and to be arranged at non-magnetic conduction sleeve 401 and be positioned at second electromagnet 4032 on the non-magnetic conduction guide pillar 402, described first electromagnet 4031 and second electromagnet, 4032 homopolarities are oppositely arranged, on described screen cloth 1, also be provided with control circuit board 5, control circuit board 5 electrically connects described first electromagnet 4031 and second electromagnet 4032 by electric wire, realizes the change of the magnetic force of first electromagnet 4031 and second electromagnet 4032.
Magnetic force by regulating magnet changes 2 spacings between the electromagnet, and then realizes the change of vibration frequency.Simultaneously, 2 electromagnet are arranged in the non-magnetic conduction sleeve respectively and on the non-magnetic conduction guide pillar, are a kind of contactless vibration columns, can effectively avoid the noise pollution problem that produces in the operating process.
The operation principle of food mixing stirring device of the present utility model is: in operating process, control circuit board by electric wire with current delivery to electromagnet, make it produce magnetic force.Because the electromagnet homopolarity is relative, 2 electromagnet are spaced-apart under the effect of repulsive force, under the acting in conjunction of vibration power plant, make screen cloth with certain frequency vibration, realize quick, the effectively screening of food.If will change vibration frequency, the electric current that only needs to regulate control circuit board changes the magnetic force of electromagnet, realizes thereby adjust 2 spacings between the electromagnet.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; in the spirit and scope of the present utility model that do not break away from appended claims and limited; can make various variations to the utility model in the form and details, be protection domain of the present utility model.
