Description

Complex frequency screen

Technical Field

The utility model relates to a multiple frequency sieve technical field especially relates to a multiple frequency sieve.

Background

The complex frequency sieve has the advantages which are not compared with other sieve grades, such as static sealing, sieve plate vibration, no vibration of a sieve box and the like, but also has the respective disadvantages; for example, the compound frequency sieve adopts a motor external-dragging vibration exciter as a power source, and in most cases, the vibration exciter is integrally cast, so that the whole weight is large.

The complex frequency sieve is used for replacing the traditional sieve machine, achieves static sealing, is energy-saving, environment-friendly and efficient, and does not participate in vibration of a sieve plate vibrating sieve box. However, the complex frequency sieve has some defects, the vibration exciter is integrally cast, the processing period is long, if the vibration exciter is changed after shaping, the mould needs to be changed, the cost is greatly increased, the vibration exciter is simpler, and the conventional complex frequency sieve can only realize the problem of single sieving. The vibration exciter adopts the biax structure, and is bulky, weight is heavy, and damping spring installs in bearing room below, and is closer apart from the bearing mounted position ratio, is difficult to the dismouting, is unfavorable for diversified design.

SUMMERY OF THE UTILITY MODEL

For overcoming the problem that exists among the correlation technique, the embodiment of the utility model provides a complex frequency sieve has solved conventional complex frequency sieve and only can realize single screening problem, and the vibration exciter adopts biax structure, bulky and heavy problem.

The embodiment of the utility model provides a compound frequency sieve, including sieve core, sieve case, unipolar vibration exciter, motor and sieve, the inside at the sieve case is installed to the sieve core, the sieve is located the top of sieve core and sets up in the inside of sieve case, the outside of sieve is fixedly connected with guide spring and balancing piece respectively, guide spring is located the top of balancing piece, sieve case and sieve fixed connection, the other end and the motor fixed connection of unipolar vibration exciter are run through to the one end of unipolar vibration exciter.

Further, the sieve box is obliquely arranged on the support, and the inclination angle of the sieve box is between ten degrees and thirty degrees.

Furthermore, the top of support is provided with the mount pad, and the top of mount pad is provided with the damping spring, and the motor is installed on the damping spring.

The embodiment of the utility model provides a technical scheme has following beneficial effect: the single-shaft vibration exciter as a vibration source has lower energy consumption, energy conservation and environmental protection, a vibration transmission mode is better, and the installation and the maintenance are convenient; the multi-frequency structure and the independent screening module have small volume, light weight and higher reliability; increase guiding spring and balancing piece, adjust the balancing piece, the variability of the vibration orbit of multiplicable whole section of adjusting sieve plate for improve the screening effect, alleviateed equipment greatly and participated in weight and power loss that shakes, reduced the degree of difficulty of preparation simultaneously, can use in more manifold non-standard trade and use.
