Abstract
The utility model discloses an electromagnetic vibrator case body of a high-frequency electromagnetic sieve. The high-frequency electromagnetic sieve mainly comprises a main frame sieve box and a plurality of electromagnetic vibrators connected with lateral plates arranged at two sides of the main frame sieve box. The electromagnetic vibrator case body is integrated with the corresponding lateral plates into an integral casting component, and the electromagnetic vibrators are intergrated into a whole through casting. The main frame sieve box and the electromagnetic vibrator case body are both made of wear-resistant alloys. The electromagnetic vibrator case body of the high-frequency electromagnetic sieve can improve the stiffness of the electromagnetic vibrator case body and the lateral plates, imporve the vibration force and the wearing resistance and prolong the service life, and is applicable to the screen separation of medium-granular and fine-granular materials in the metal mineral processing industry.
Description
Technical field
The utility model relates to metal ore dressing industry, is specifically related to a kind of high-frequency electromagnetic of using and sieves and the integrated vibrator casing of side plate when the ferrous metal ore dressing.
Background technology
In the metal ore-dressing practice, for example in the iron ore beneficiation, iron ore is carried out series of selection and refinement operation.The electric and magnetic oscillation high frequency shale shaker is a kind of screening plant commonly used that present centering, fine granular materials sieve.The structure of the host machine part of existing high-frequency electromagnetic sieve as shown in Figure 1.The structure of this high-frequency electromagnetic vibratory sieve mainly comprises two parts, be main frame screen box 1 and electromagnetic vibrator 2, electromagnetic vibrator is the vibration source of vibratory sieve, and several electromagnetic vibrators 2 are located at the side plate both sides of main frame screen box 1, balanced configuration, the structure of electromagnetic vibrator as shown in Figure 2.The source of its vibration source is the magnetic field that is produced by the electromagnet 5 energising backs that are installed in the vibrator casing 8, utilizes the alternating voltage of 50HZ/ second to produce 3000 times/minute vibration frequency.This vibrator also is provided with 2 groups of rubber springs, be primary elastomeric spring 3 and secondary rubber spring 6, by the vibration force of electromagnet 5 with the combination results of rubber spring 3,6, pass to after connecting rod 4 produces a powerful torsion by power transmission screw rod 7, pass to the beating unit below the screen cloth in the main frame screen box 1 again, make screen cloth vibrate into the jump form and carry out work.
Each all is casing independently for this existing electromagnetic vibrator casing, each casing all is welded on the corresponding side plate of main frame screen box separately separately, both sides these vibrators of thin plate independent support of making by general steel plate, this just makes the rigidity of main frame screen box poor, a little less than the vibration force, all bring adverse effect for the effect of excited frequency and screening.
The utility model content
Sieve the deficiency that the rigidity of its main frame casing and side plate is poor, influence vibrating effect in order to overcome existing high-frequency electromagnetic, the purpose of this utility model is: the vibrator casing that a kind of high-frequency electromagnetic sieve is provided, the side plate of this vibrator casing and high-frequency electromagnetic sieve is a monolithic construction, the rigidity of vibrator casing and side plate be can improve, vibration force and screening effect improved.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
A kind of vibrator casing of high-frequency electromagnetic sieve, this high-frequency electromagnetic sieve mainly comprises main frame screen box and the some electromagnetic vibrators that are connected with the side plate of main frame screen box both sides.The casing of described electromagnetic vibrator all with the be formed in one monoblock cast part of structure of corresponding side plate, several electromagnetic vibrators link into an integrated entity by casting.
Described main frame screen box is the main frame screen box that antifriction alloy is made, and the casing of described electromagnetic vibrator is the electromagnetic vibrator casing that antifriction alloy is made.
Because adopt technique scheme, the utility model compared with prior art has following beneficial effect:
1, improved the rigidity of vibrator casing and side plate, vibration force is improved
The utility model is owing to adopted the casing of vibrator and structure that the side plate of electromagnetic sieve main frame screen box is formed in one, and several vibrator casings connect as one, such overall structure is strengthened the rigidity of vibrator casing and side plate, improved the integral rigidity of equipment, thereby make vibration force place compass screen surface fully, improved the vibrating effect of compass screen surface.Vibration force can greatly improve than the design of former prior art.
2, improved the wearability of equipment
The casing of main body screen box of the present utility model and electromagnetic vibrator is made by wear resistant alloy material, compares with the general steel plate manufacturing with existing, and the utility model can improve the wearability and the service life of equipment.

Among the figure, 1. main frame screen box 2. electromagnetic vibrators 3. primary elastomeric springs 4. connecting rods 5. electromagnet 6. secondary rubber spring 7. power transmission screw rods 8. vibrator casings 9. bearings 10. secondary shock-absorbing springs 11. frames 12. integral vibration damping springs 13. side plates
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Figure 3 shows that an embodiment of the present utility model, the structure of figure medium-high frequency electromagnetic sieve is divided into two bodies, i.e. main frame screen box 1 and electromagnetic vibrator 2.Main frame screen box 1 is supported by 4 bearings 9 of frame 11, is placed on the structural member base of integral assembly welding.An integral vibration damping spring 12 respectively is equipped with at four angles, the bottom surface of base, and a secondary shock-absorbing spring 10 respectively is equipped with in the bottom of bearing 9.In the present embodiment, on the side plate 13 of main frame screen box 1 both sides, respectively be provided with four electromagnetic vibrators 2, be symmetrical arranged.These 8 electromagnetic vibrator casings 8 all with the be formed in one monoblock cast part of structure of corresponding side plate 13, thereby 4 vibrator casings of each side become one by casting.Main body screen box 1 and integrated with it vibrator casing 8 are made by wear-resisting alloy steel, and the rubber damping spring is also made by high-abrasive material.
