The utility model is characterized in that a screen frame is connected with a stander through supporting springs arranged at the outer sides of two side plates, and an excitation post is transversally connected to the upper part of the screen frame between the side plates; two high-frequency excitation motors controlled through a variable frequency lcp (local control panel) are fixedly mounted on the excitation post, and the axes of the high-frequency excitation motors are parallel to the axis of the excitation post and are adjustable from 30 degrees to 50 degrees corresponding to a mounting angle of either vibration screen plate; either vibration screen plate in the screen frame comprises a back plate and a flat plate and is made of polyurethane, screen holes are in slot shapes, and a feeder is mounted directly above the screen plane of the slot of the back plate. The utility model has simple structure, smart design and high operation stability, and the electric power consumption for running the whole unit is lower than 10 kw/h.

Description

The dither dewater unit

Technical field

The utility model relates to a kind of dither dewater unit.

Background technology

At present, in fine particle stage material dehydration common technique, adopt equipment such as centrifuge, disk filter, band filter, ceramic filter, plate and frame filter press mostly, but all have following several respects problem: the complicated dependability of equipment is poor, as centrifuge; Be not suitable for handling than fine particle stage material, filter is not done, as ceramic filter, band filter and disk filter; Discontinuous formula production is as plate and frame filter press.And above filter plant exists cost height, energy consumption is big and operating cost is high weakness.

The utility model content

In order to overcome the weak point that above-mentioned prior art exists, the purpose of this utility model provides a kind of dither dewater unit, and it can carry out sound solid-liquid separation dehydration to fine particle slurry material.

The purpose of this utility model realizes in the following way: a kind of dither dewater unit, dispenser is arranged, the high-frequency excitation motor, the VFC cabinet, support spring, screen frame, oscillating screen plate, parts such as frame, surround a screen frame by two blocks of side plates and the oscillating screen plate that is fixed within the side plate, be connected with the minus mesh collecting box below the screen frame, it is characterized in that: screen frame is connected with frame by the support spring that is positioned at the biside plate outside, screen frame upper lateral between biside plate is connected with the exciting post, be installed with two high-frequency excitation motors on the exciting post by the control of VFC cabinet, the axis of high-frequency excitation motor is parallel with the exciting mast axis, its setting angle with respect to oscillating screen plate be 30～50 ° adjustable, method of adjustment is to fixedly connected with biside plate after the exciting post is rotated the angle of needs again.Oscillating screen plate in the screen frame is formed by connecting by backboard and flat board, oscillating screen plate is the polyurethane manufacturing, described sieve aperture is a bar seam shape structure, and the angle theta that forms between backboard and the flat board=115～135 °, dull and stereotyped wedge wire screen face inclination angle with respect to the horizontal plane be 2～15 ° adjustable, method of adjustment is to regulate the installation site of slat slotted screen face by lowering or hoisting gear; Dispenser be installed in backboard wedge wire screen face directly over.

Described shock electric machine frequency is 900～3000 times/minute, and amplitude is 0.1～5mm, power 2～10KW.

The support spring of described damping effect is the cylindricality support spring that polyurethane material is made, and its diameter is at φ 50～200mm, and height is at 100～300mm.

The compass screen surface of the oscillating screen plate of described polyurethane manufacturing is the wedge wire screen face, and sieve seam width w selects for use in 0.10～0.8mm scope according to different minerals material character.

The advantage and the good effect of this device are: the Separation of Solid and Liquid that 1, is applicable to the very thin material of grade, reach 60% high fineness material as-400 orders in mine ore dressing mine tailing, the concentrate, under 40～65% feed concentration, it can be dewatered to moisture content below 15%, this is that existing equipment is inaccessible.2, because of using the high-frequency excitation motor to make the vibration source of dewatering screen, fine particle stage material can resonate and unite and form the filtration bed, and thin material is blocked, and water can see through bed and takes off from sieving down, moisture content can be low to moderate below 15% according to the material difference, and the device processes ability is from 5～100 tons of/hour platforms.3, owing to can regulate to the compass screen surface setting angle of high-frequency excitation motor pendulum and oscillating screen plate, thereby reach adjustment to exciting force, under reasonable parameter such as compass screen surface, the size of screen(ing) machine own, electric machine frequency and position angle cooperate, can reach best dehydrating effect.4,, wear-resisting, putty, equipment do not operate steadily because oscillating screen plate, support spring all adopt the polyurethane manufacturing.5, because shock electric machine adopts the control of VFC cabinet, thereby the technology adjustment that adapts to the heterogeneity material guarantees dewater unit stable operation, all can use this device in mine ore dressing, metallurgy, colliery, chemical industry, building sandstone material field.6, dewater unit is simple in structure, design ingenious, the operation stability height, the power consumption of complete machine operation is lower than 10KW/h.
