Description

Anti-adhesion device for drum screen

Technical Field

The utility model relates to a shale shaker accessory field, concretely relates to antiseized even device of drum sieve.

Background

The drum screen is a machine widely applied in the sorting technology, the material sorting is controlled by the particle size of the particles, and the sorting precision is high. However, some materials with the size about the same as the pore size are easy to block meshes or adhere to the wall of the drum screen, so that the anti-adhesion device for the drum screen is very important.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the above-mentioned problem, the utility model provides an antiseized even device of drum sieve, including the drum sieve, the rotatory motor of control drum sieve, support the drum sieve and carry out the support of rotation under motor control, the setting is used for storing the feed bin of undersize thing in the support bottom, still including setting up the rapping device in the drum sieve top and the contact of drum sieve, rapping device is including rapping the support, rapping motor and rapping wheel, every position of rapping wheel surface is all inconsistent apart from the distance in the centre of a circle, and increase in succession until fracture formula descends, rapping wheel receives rapping motor control, swivelling joint is on rapping the support, the drum sieve surface is always contacted with rapping wheel, be fixed with compression spring between support and the feed bin bottom. One end of the compression spring is welded with the bottom of the rapping bracket, and the other end of the compression spring is welded with the bottom of the storage bin.

Through the technical scheme, because the rapping wheel has fracture formula decline, then in a decline moment, under the effect of spring, the drum sieve can take place vibrations, can solve the drum sieve and can appear material adhesion sieve section of thick bamboo inner wall in the use, the material granule card scheduling problem in the mesh of screen cloth.

As a preferred mode of the above, the rapping devices are provided in several numbers, with the distance between two adjacent rapping devices being identical. The compression springs are provided with a plurality of and are evenly fixed between the support and the bottom of the storage bin, so that vibration can be generated, and the adhered substances on the cylindrical roller screen are shaken down.

The rapping bracket is welded at the top ends of the two side walls of the storage bin. The rotary connection parts are integrally formed at the two ends of the rapping wheel and are connected with the rapping support through bearings, and the bearings support the rotation of the rotary connection parts, so that the friction coefficient in the motion process is reduced, and the rotation precision of the rapping wheel is ensured.

Compared with the prior art, the utility model has the advantages of: because the vibrating wheel is in fracture type descending, the drum screen can vibrate under the action of the spring at the moment of descending, so that the problems that materials are adhered to the inner wall of the screen cylinder, material particles are clamped in meshes of the screen mesh and the like in the use process of the drum screen can be solved; the rapping devices are provided with a plurality of rapping devices, and the distance between two adjacent rapping devices is consistent, so that vibration can be generated, and the substances adhered to the cylindrical drum screen can be shaken down.

Detailed Description

Referring to the attached drawing, the utility model discloses a following technical scheme, the antiseized even device of drum sieve, including the drum sieve, the rotatory motor of control drum sieve, support the drum sieve and carry out the support of rotation under motor control, the setting is used for saving the feed bin of undersize thing in the support bottom, still including setting up the rapping device in the drum sieve top and the contact of drum sieve, rapping device is including rapping the support, rapping motor and rapping wheel, the distance of every position distance centre of a circle on rapping wheel surface is all inconsistent, and increase in succession until fracture formula descends, rapping wheel receives the control of rapping motor, swivelling joint is on rapping the support, the drum sieve surface is always contacted with rapping wheel, be fixed with compression spring between support and the feed bin bottom. One end of the compression spring is welded with the bottom of the rapping bracket, and the other end of the compression spring is welded with the bottom of the storage bin. Wherein the trommel is rotated on the support under the action of the motor to form an existing trommel connecting structure.

Because the rapping wheel has fracture formula decline, then at a moment of decline, under the effect of spring, the drum sieve can take place vibrations, can solve the drum sieve and can appear material adhesion sieve section of thick bamboo inner wall in the use, the material granule card scheduling problem in the mesh of screen cloth. The direction of rotation of the rapping wheel in the shape shown in fig. 2 is clockwise.

The rapping devices are provided with a plurality of rapping devices, and the distance between every two adjacent rapping devices is consistent. The compression springs are provided with a plurality of and are evenly fixed between the support and the bottom of the storage bin, so that vibration can be generated, and the adhered substances on the cylindrical roller screen are shaken down.

The output shaft of the rapping motor is fixedly connected with the rotary connecting part through a coupler. The rapping motor is fixed on the rapping bracket.
