Abstract

The invention belongs to the technical field of feeding and burdening equipment in metallurgical and coking industries and relates to a vibrating screen which comprises a chute baseplate and at least one angle-steel-shaped coke distributor with a sharp portion upwards to be fixed on the chute baseplate. The angle-steel-shaped coke distributors are fixed on the chute baseplate, and the coke distributors with the sharp portions upward are used for relieving impact force generated during material falling, so that next process equipment is protected, materials which are originally gathered together are uniformly distributed on the screen surface, effective screening area is increased, the service life of the equipment is prolonged, and production efficiency of the equipment is greatly improved. As a further improvement, the coke distributors in number of three are distributed in the shape of Chinese character ' ', and for the convenience of replacement, each coke distributor is fixed by adopting bolts.

Description

Vibratory sieve

Technical field

The invention belongs to metallurgical coking industry feed, dispensing equipment technical field, relate in particular to the few material screening of moisture such as a kind of coke and the vibratory sieve of broken usefulness.

Background technology

In the metallurgical mine industry, the domestic general equipment component material systems of processing such as vibratory sieve, disintegrating machine that adopt at present, and in process of production, disintegrating machine or vibratory sieve equipment be must run into and place's excessive wear or breaking length and screening effective area problem of smaller fallen at material, cause production efficiency low, the phenomenon of low load with strong power occurs.

Summary of the invention

At above-mentioned technical problem, the object of the present invention is to provide a kind of vibratory sieve, make material when entering next process equipment, can scatter as far as possible, enlarge the screening effective area on the one hand, make the compass screen surface wearing and tearing evenly on the other hand, prolong the equipment life cycle.

For solving the problems of the technologies described above, the technical solution used in the present invention is, a kind of vibratory sieve comprises the chute base plate, and described vibratory sieve comprises the burnt device of the branch of at least one angle steel shape, and the sharp portion of the burnt device of described branch is fixed on the chute base plate up.

Vibratory sieve of the present invention; employing the chute base plate fixedly the angle steel shape divide burnt device; alleviate the impulsive force that produces in the material falling process by the burnt device of sharp portion branch up; protected next process equipment; also make simultaneously the material that concentrated in together originally; be uniformly distributed in compass screen surface, increased effective sifting area, reach and improve service life of equipment, improve the beneficial effect of production efficiency of equipment greatly.

Description of drawings

Fig. 1 is vibratory sieve operation principle structural representation of the present invention;

Fig. 2 be among Fig. 1 A to partial schematic diagram.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is made and to further specify.

As shown in Figure 1, 2, dried material such as coke etc. fall in chute 2 by the conveying of belt feeder 3, last landing is on compass screen surface 1, vibratory sieve of the present invention is fixed at least one angle steel shape at chute 2 base plates and is divided burnt device 4, divides the sharp portion of burnt device 4 up, and the material of landing is owing to divide stopping of burnt device 4, slow down the impulsive force to compass screen surface 1, simultaneously material is evenly distributed at compass screen surface, has increased effective sifting area, improved device efficiency.

As preferably, the burnt device of the branch shown in the figure is three, makes " product " font and arranges, by that analogy, when chute 2 width strengthen, divides the quantity of burnt device also because doing corresponding increase, does the pyramid distribution; Divide burnt device can be welded on the chute base plate, for ease of changing, each divides burnt device also can adopt the mode of bolting.

The description of above embodiment is comparatively concrete, detailed; but can not therefore be interpreted as the restriction to this patent scope; should be noted that; for the person of ordinary skill of the art; without departing from the inventive concept of the premise; can also make some distortion and improvement, these all belong to protection scope of the present invention.

Claims (3)

1. a vibratory sieve comprises the chute base plate, it is characterized in that: described vibratory sieve comprises the burnt device of the branch of at least one angle steel shape, and the sharp portion of the burnt device of described branch is fixed on the chute base plate up.

2. according to the described vibratory sieve of claim 1, it is characterized in that: the burnt device of described branch is three, makes " product " word shape and distributes.

3. according to claim 1 or 2 described vibratory sieves, it is characterized in that: the burnt device of described branch adopts welding or bolted fixed form.
