Description

High frequency shale shaker

Technical field

Vibratory sieve is the utility model is related to, more particularly to a kind of high frequency shale shaker.

Background technology

High frequency shale shaker abbreviation high-frequency screen, can be not only used for the separation of material particles, can be also used for surface of material water That divides is predrying.High frequency shale shaker is made up of parts such as screen frame, motor, eccentric shaft, pendulum spring and sieve plates.High frequency vibrating Dynamic sieve employs high-frequency, destroys the tension force of surface of material so that material vibrates at a high speed on sieve plate, accelerates material table The separation of face moisture, so as to cause preferable separation condition, therefore high frequency shale shaker has extensively in the dry field of material pre-drying Application prospect.

But the sieve screen apertures of existing high frequency shale shaker (such as vibratory sieve of German SKG companies production) are rectangular, right During some material higher-orders of oscillation, material is easily stuck in sieve screen apertures, is blocked sieve screen apertures, is not only reduced predrying efficiency, also increase Shutdown maintenance rate.And only the vibrations by high frequency shale shaker can't thoroughly remove the moisture of surface of material, it is also necessary to vibrate The exit side of sieve increases other drying equipments, and not only floor space is wide, and energy consumption is larger.

Utility model content

The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of high frequency shale shaker, the vibratory sieve exist It is hanging above screen frame that two blowing covers are set, the vaporization of material surface moisture is added to material blowing hot-air, improves predrying efficiency.

In order to solve the above technical problems, the utility model provides a kind of high frequency shale shaker, including base and screen frame, on base Four groups of spring bases are fixed, helical spring lower end is set on spring base and is fixedly connected with base, the top of helical spring and peace Dress seat is fixedly connected, and described screen frame includes two blocks of side plates being oppositely arranged, and respectively there is a mounting post biside plate rear and front end, peace The both ends of dress post are separately fixed in mounting seat；The centre of biside plate is fixed with sieve plate, and several are evenly distributed on sieve plate Sieve screen apertures；Centre position is provided with two eccentric drive shafts between biside plate, described eccentric drive shaft passes through spherical roller Bearing is arranged between biside plate, and eccentric drive shaft is vertical with material trend, and the both ends of two eccentric drive shafts are respectively coupled There is governor weight block, two governor weight blocks of the same side are arranged in same counterweight cover, and two counterweight covers are separately fixed at The outside of two blocks of side plates, one of side plate outside are provided with electric machine support, and described electric machine support separates with screen frame, electric machine support On be fixed with two motors, the ring flange of every motor all passes through a Cardan shaft and the flange of an eccentric drive shaft Disk is fixed；Also include covering along two blowings that material moves towards to set, described blowing cover is vacantly arranged on two by four suspension rods Between block side plate, blowing cover separates with screen frame, and blowing cover top is provided with blast pipe, and blowing cover bottom is provided with air outlet.

High frequency shale shaker of the present utility model is to be engaged by two eccentric drive shafts with the governor weight block of external add-in Caused by exciting, the supporting of eccentric drive shaft is realized by the spheric roller bearing dedicated for vibrating machine, vibratory sieve Side plate is formed by the carbon structural steels cutting of deoxidation, and the eccentric drive shaft supporting area on side plate is reinforced with additional steel plate. Vibratory sieve is arranged on special helical spring, and it is excellent that helical spring makes vibratory sieve obtain the vibration damping of ground and base Change, so as to reduce the dynamic loading being delivered on ground.Vibratory sieve is directly driven by a motor, the power between motor and vibratory sieve Transmitted by a Cardan shaft, the length and angle that Cardan shaft can occur in operation to vibratory sieve Deviation is adjusted, and makes the vibration of screen frame be unlikely to be delivered on motor and electric machine support whereby.It is hanging above screen frame to set Two blowing covers be used for material blowing hot-air, accelerate the vaporizations of surface of material moisture, improve predrying efficiency；Blowing cover utilizes Four suspension rods hang and are located on crossbeam, are not contacted with screen frame, avoid blowing cover from vibrating and shake with screen frame.

Further, the longitudinal section of described sieve screen apertures is in "eight" shape, and existing rectangular sieve mesh hole is easily blocked up by material Plug, the water droplet that vibration is got off is seted to be stained with again by material below in oscillatory process from being drained to by sieve screen apertures below sieve plate Arrive, reduce predrying efficiency；Sieve screen apertures are arranged to "eight" shape, though sieve screen apertures top half by feed blocking, due to sieve Mesh gradually increases, and sieve screen apertures lower half can also be entered by the gap between material and sieve screen apertures by vibrating the moisture to get off Part, and then fall on below sieve plate, predrying efficiency is improved, reduces the time of shutdown maintenance.

Closer, screen frame bottom plate is fixed between biside plate, screen frame bottom plate is divided into several grids, Mei Gefang One piece of sieve plate is fixed in lattice.With high frequency shale shaker much time using, a certain degree of abrasion can occur for sieve plate, or It can be blocked by some tiny material, impurity etc., it is necessary to which timing is changed, during replacing, it is only necessary to serious wear or block serious One of sieve plate is changed, it is not necessary to is changed whole sieve plates, is reduced use cost.
