Abstract
A novel vibration exciter with a high force-mass ratio adopts common vibration-proof motors or explosion-isolation vibration-proof motors (1) which are respectively connected with two or more eccentric mass blocks (4) through shaft couplings (2) and transmission shafts (3) respectively located on the two ends of each motor. The eccentric mass blocks are supported by bearing seats (6) equipped on the side plates which are located on the two sides of a screen case to realize the transmission of motion and exciting force. Meanwhile, energy saving service-life-prolonging control circuits (7,8) equipped inside an electric appliance control switch box are adopted to alternately supply and cut power to two or more motors. By adopting the vibration exciter in the utility model, a vibratory screen can have the dynamic characteristic parameters such as the amplitude, the throwing index and the shaft diameter ratio of a vibration mode track long shaft to a vibration mode track short shaft, etc. greatly improved. As to a double-motor elliptical vibratory screen, the vibration exciter can more effectively improve the force-mass ratio (the relationship between the exciting force magnitude of a vibration exciter and the own mass of the vibration exciter). The vibration exciter which is simple in structure and convenient to manufacture can loosen the strict installing requirements and improve the bearing of the screen case. Furthermore, the vibration exciter has a low cost and a wide application.
Description
Technical field
The utility model relates to the vibratory sieve of mud conditioning, muddy water processing and material screening and conveying, comprises the vibratory sieve that uses in the industry department operations such as oil and gas well drilling, ore dressing, coal separation, chemical industry, medicine, food, non-ferrous metal, Hydraulic and Hydro-Power Engineering, underground space engineering, city construction engineering and transmission.
The utility model is a kind of novel vibrator that is used for a kind of high-tensile strength matter ratio of equipment such as vibratory sieve.This vibrator adopts to be installed on the screen box joins generally common (or flame proof) the antivibration motor (1) that the shakes shaft coupling (2) by two ends with screen box and is connected with two or more eccentric massblocks (4) respectively with power transmission shaft (3).Eccentric massblock is realized the transmission of motion and exciting force by bearing block (6) supporting that is installed on the side plate of screen box (9) both sides.Simultaneously, adopt be installed on the whole sieve base the energy-saving, service life prolonged control circuit (7,8) in the electric control switch case to two or multiple electric motors in turn for, outage, reach the purpose that electrical machine energy-saving is lengthened the life.
Background technology
Development along with the motor synchronizing technology, all types of self-synchronizing vibrating screens, basically all adopt shock electric machine directly the ginseng mode of shaking turn round, this has just proposed the more and more requirement of harshness to the quality of shock electric machine and technical conditions etc., particularly to big exciting force vibrator.Simultaneously, when big exciting force was required, the quality requirement to excitation system self was light more good more again.This contradiction is very sharp-pointed.Especially in oil drilling vibratory sieve for example, " bottleneck " problem that has become the type vibratory sieve to further develop.And existing shock electric machine, because its exciting force size is achieved by a variety of factors with " power matter ratio " (being the ratio of the size and the sole mass size of power) of sole mass size, be difficult to be further improved, particularly be difficult to be greatly enhanced, therefore, press for technically and can have breakthrough, with the particular problem of the raising excitation system self that solves the task of top priority " power matter than ".
For this reason, design has proposed a kind of novel vibrator of high-tensile strength matter ratio.This vibrator both can be directly installed on realizes self-synchronization exciting on the screen box, simultaneously, adopt variable frequency starting with energy savings greatly and can realize easily lightweight, large span, small-power, big exciting force, energy-conservation, lengthen the life, multiple uses such as flame proof and non-flame proof.Can apply widely on the relevant self-synchronizing vibrating screen of a lot of industries.
Summary of the invention
The utility model has designed a kind of novel vibrator of high-tensile strength matter ratio.
This novel vibrator is connected with two or more eccentric massblocks (4) respectively by shaft coupling (2) power transmission shaft (3) of common (or flame proof) antivibration motor (1) by two ends.Eccentric massblock is realized the transmission of motion and exciting force by bearing block (6) supporting that is installed on the side plate of screen box both sides.Because this vibrator is in the vibratory sieve operation process, mainly be to provide radially exciting force acting by the rotating eccentricity mass, torque is very little after electric motor starting enters steady running, so motor is to the demand of the providing energy, just bigger when starting, and power demand is just very little after entering steady running, so this vibrator adopts variable frequency starting to reach the purpose of energy savings.Because novel vibrator sole mass alleviates and exciting force can improve greatly greatly, therefore, the diameter of axle that adopts this novel vibrator just can improve the relevant dynamic characteristic parameter of vibratory sieve such as amplitude, throwing index, vibration shape track major and minor axis greatly compares or the like.
Simultaneously, this novel exciter structure is simple, it is easy for installation, with low cost to make, be widely used, and than the special-purpose shock electric machine of present employing, its cost performance can obtain the raising of very big amplitude.
The technical solution adopted in the utility model is: as shown in Figure 1 and Figure 2, common (or flame proof) antivibration motor (1) is connected with two or more eccentric massblocks (4) respectively by shaft coupling (2) power transmission shaft (3) at two ends.Eccentric massblock is realized the transmission of motion and exciting force by bearing block (5) supporting that is installed on the side plate of screen box (9) both sides.Motor makes two or multiple electric motors carry out variable frequency starting by being installed on the whole sieve base frequency converter in the electric control switch case and energy-saving, service life prolonged control circuit (7,8); and take turns for, outage, to reach the energy-conservation of motor and the protection of lengthening the life to two or multiple electric motors according to the requirement of setting.
Compared with prior art, the advantage of the utility model patent is:
(1) since this novel vibrator sole mass alleviate raising with exciting force, can further improve with the diameter of axle of the relevant dynamic characteristic parameter that improves vibratory sieve such as amplitude, throwing index, vibration shape major and minor axis and compare etc., thereby, can further improve the overall dynamics performance of vibratory sieve.
(2) adopt this novel vibrator for the oval vibration shape vibratory sieve of bi-motor, under guaranteeing that its big or small exciting force power value is than constant prerequisite, power matter that can more efficiently raising vibrator is than (being the exciting force size of vibrator and the ratio of vibrator sole mass), and this advantage, elemental body twin shaft motor synchronizing balanced elliptic inertia vibrating screen for China has the leading level in the world has very important practice significance.
(3) because this novel vibrator adopts variable frequency starting and take turns therefore, can effectively reach the energy-conservation of motor and the protection of lengthening the life for, outage to two or multiple electric motors by energy-saving, service life prolonged control circuit in the motor rotation course of work.
(4) adopt this novel vibrator, because the novelty and the validity of its structure, can relax vibrator on screen box and the strict demand of sieve box side plate middle part when installing, and, can also improve the stressing conditions of screen box greatly, help improving the service life and the reliability of screen box.
(5) this exciter structure simple, make easy for installation, with low cost, be widely used, can obtain the raising of very big amplitude than the present cost performance that adopts special-purpose shock electric machine.
