Abstract
The invention relates to a cylindrical screen for separating solid materials, which comprises a driving shaft, a rotating screen drum and a driving part. The driving shaft is mounted on a supporting frame, the rotating screen drum is driven by the driving shaft, and the driving part provides power for the driving shaft. A distributor with a through groove is mounted on the hollow side wall of the rotating screen drum, and a hollow shaft at one end of the distributor is also used as a material feeding hole. The distributor adopted by the cylindrical screen can relatively and evenly distribute solid materials in the rotating screen drum so that rotating and screening the rotating screen drum can not generate great weight center bias due to material concentration.
Description
Technical field
The present invention relates to a kind of drum sieve that is used for separating solid materials.
Background technology
Drum sieve is the equipment that is used to sieve solid material.Existing drum sieve generally includes and rotates screen drum and be installed in driving shaft on the bracing frame, and for driving shaft provides the driver part of rotatory force, and be provided with screen cloth or grating at the periphery that rotates screen drum.This drum sieve is utilize to rotate screen drum sieve solid material in rotating process, be it in supply in advance sieve material from one end face usually and rotate screen drum when rotating, and it is that the oversize materials flow goes out the position that the other end is set at large granular materials.For rotating screen drum, owing to it needs driving shaft to support and drive it to rotate, and driving shaft must be arranged on the end face centre of rotating screen drum, so driving shaft can influence the material supply and the oversize material that rotate screen drum and discharge.
In order to address the above problem, the name of Chinese patent 100430157C number mandate branch bulletin is called " cylinder screening equipment " and provides a solution.This equipment adopts two to be installed in the rolling ring of supporting on the carrying roller respectively, outer fixed support and internal layer fixed support are installed between two rolling rings, and form the sieve nest of truncated cone-shaped, equipment has screen cloth or grating on each layer fixed support, centre in big rolling ring is provided with the connecting axle that is connected with driving mechanism, be the outside that connecting axle only is arranged on sieve nest, do not have to adopt the structure of passing sieve nest.This equipment utilizes driving mechanism to drive sieve nest by connecting axle and rotates when work.Though two rolling rings adopt rolling to cooperate with supporting carrying roller, but frictional resistance reduced, but because the distance between connecting axle and the support carrying roller is bigger, connecting axle needs relative to big torque sieve nest is rotated when rotating; Simultaneously can't be totally-enclosed because of rolling ring and support carrying roller position, thus this position is easily polluted by the material that is sieved or other material, cause frictional resistance to increase; In addition, after the solid material that is sized enters in the sieve nest in the rolling ring, if the negligible amounts of input material, then influence its screening efficiency, if the quantity of input material is bigger, can cause sieve nest to lay particular stress in the moment of charging, cause the increase of driving force, and can influence the efficient of screening too, reduce the service life of sieve nest.
People generally believe that the solid material that is sized will be from rotating an end face input of screen drum, after this material divides through the trundle screen shaft screen, the oversize material also will flow out through the other end of rotating screen drum, if axially pass the structure of rotating screen drum if driving shaft adopts, the part of driving shaft in rotating screen drum can be subjected to the continuous bump of solid material on the one hand, cause it easily to damage too early, on the other hand, being arranged on the driving shaft that rotates the screen drum feed end can influence the input of material, so, mistaken ideas of the prior art are that driving shaft can not axially pass the rotation screen drum, and driving shaft is installed in and rotates outer can the causing to it of screen drum and lay particular stress on serial problems such as rotating torque increase.
Summary of the invention
Task of the present invention provides a kind of mode of utilizing sub-material and solve the drum sieve of laying particular stress on the separating solid materials of problems such as rotating torque is big when the screening material.
The drum sieve of separating solid materials proposed by the invention comprises the driving shaft that is installed on the bracing frame and by the shaft-driven rotation screen drum of this active, and the driver part that rotatory force is provided for driving shaft, the sidewall that hollow also is installed in the rotation screen drum is provided with the tripper of groove, and an end of this tripper is the quill shaft of double as material input port.
The other end that described tripper is relative with quill shaft is provided with and is used for the axially extending bore that is connected with driving shaft.
Described rotation screen drum comprises two rigidity annulus and the skeleton that is made of rod member that axially is connected two rigidity annulus, and the screen cloth or the grating that are enclosed in this skeleton periphery, the middle part of rotating an annulus of screen drum be provided with the wheel hub that is connected with driving shaft and be installed in wheel hub with this annulus between spoke, another annulus of rotation screen drum is fixedlyed connected with quill shaft by connector.Described rotation screen drum is cylindrical or truncated cone-shaped.
The below of described rotation screen drum is equipped with the undersize funnel, and the below of cylinder wheel hub is equipped with the oversize funnel.
On the bracing frame of described quill shaft one side feed box is installed, the outlet of this feed box extends in the quill shaft.
The tripper that the drum sieve of separating solid materials proposed by the invention adopts can rotate solid material in the screen drum relative to being evenly distributed in, so that it is in the trundle screen timesharing, can not concentrate to make and rotate the very big skew of screen drum center of gravity generation because of material, not only can increase the service life, but also reduce rotatory force that it is applied; Tripper axially extended while in rotating screen drum can directly be connected with driving shaft, makes driving shaft can axially pass the rotation screen drum, with further reduction to rotatory force that it was applied; In addition, tripper just is made of the hollow that sidewall is provided with groove, and himself cost is lower, so can not increase how many costs of manufacture of drum sieve.
