Abstract

The utility model provides a vibrating screen. The vibrating screen comprises a screen tray and a base, and at least two balance springs are arranged between the screen tray and the base. A vibrator, a motor and a regulator connected with the motor and used for regulating the vibration amplitude and frequency are arranged in the base. The vibrator is connected with the motor and drives a vibrating shaft to vibrate. A plurality of layers of vibrating screen nets are arranged in the screen tray and are detachably fixed to the vibrating shaft. First discharge ports are arranged on the connection position between the bottom face and the side walls of the screen tray. Second discharge ports are arranged in the positions, located between the vibrating screen nets, of the side walls of the screen tray. According to the vibrating screen, the second discharge ports are arranged between the vibrating screen nets, so an operator can conveniently remove residues or materials on the corresponding vibrating screen nets firstly when needed, and then the operator can taken out the vibrating screen nets, so the vibrating screen is convenient to use, capable of preventing the materials from spilling out or dropping and causing waste and inconvenience, and improves the replacement, repair and maintenance work.

Description

Vibratory sieve

Technical field

The utility model relates to screening plant field, in particular to a kind of vibratory sieve.

Background technology

Vibratory sieve is to utilize type vibration and the work of revolving of answering that oscillator exciting produces, such as linear vibrating screen, circular shale shaker, high frequency shale shaker etc., there is the advantages such as amplitude is large, vibration is strong, efficiency is high, the number of plies is many, consume less, noise is low, reliable and stable, be the first-selected plant equipment of processing difficult screening materials carrying, play an important role in fields such as food processing, building, electric power chemical industry, mine, coal, smelting, building materials, refractory materials.

The material meeting the demands in order to filter out granularity, need to be by screening layer by layer, and existing method is generally repeatedly to screen, and carries out screening again and again by the sieve of different screen numbers, is finally met the material that granularity requires.But, such multiple field screening installation has met final granularity requirement, all often only below bottom one deck sieve, discharging opening to be set, and thereby sieve in the middle of needing to take out is while pouring out residue, if or the situation such as certain one deck sieve generation obstruction or sieve aperture damage that is positioned at centre needs to change, in taking out this sieve, be inconvenient, and the material above sieve easily spill or drain on the sieve of lower one deck in the time taking out.

Utility model content

The utility model object is to provide a kind of novel vibratory sieve, can effectively solve the problem running into when sieve in above-mentioned prior art is changed.

For reaching above-mentioned purpose, the technical scheme that the utility model adopts is as follows:

A kind of vibratory sieve, comprise screen tray and base, between described screen tray and base, be provided with at least two balancing springs, in described base, be provided with vibrator, motor and be connected with motor and for regulating the adjuster of Oscillation Amplitude and frequency, vibrator connecting motor also drives vibrating shaft vibration, in described screen tray, having multi-layer vibration screen cloth is removably fixed on described vibrating shaft, the bottom surface of described screen tray and the link position of sidewall are installed one first discharging opening, and the position on the sidewall of described screen tray between Multilayer vibrating screen net is provided with the second discharging opening.

Further, described the first discharging opening and the second discharging opening are provided with the valve switch of controlling discharging.

Further, described screen tray and base are disc, and described balancing spring is arranged on the edge of screen tray.

Further, described multi-layer vibration screen cloth according to barrel hole size along the descending from top to bottom of described vibrating shaft.

Further, described motor is AC induction motor.

From above the technical solution of the utility model, the beneficial effects of the utility model are by the second discharging opening is set between multi-layer vibration screen cloth, operating personnel can first be got rid of the residue on corresponding vibration screen or material aspect in needs, and then taking-up vibration screen, easy to use, and prevent spilling or leaking down of material, and cause waste and inconvenience, improve replacing, R and M work.

Accompanying drawing explanation

Fig. 1 is the example arrangement schematic diagram of vibratory sieve.

The specific embodiment

In order more to understand technology contents of the present utility model, especially exemplified by specific embodiment and coordinate appended graphic being described as follows.

As shown in Figure 1, according to preferred embodiment of the present utility model, vibratory sieve comprises screen tray 1 and base 2, between screen tray 1 and base 2, is provided with at least two balancing springs 9, and preferably, screen tray 1 and base 2 are for disc designs, and balancing spring 9 is arranged on the edge of screen tray.

In base 1, be provided with vibrator 3, motor 4 and be connected with motor and for regulating the adjuster 5 of Oscillation Amplitude and frequency, vibrator 5 connecting motors 4 also drive vibrating shaft 10 to vibrate, in screen tray 2, having multi-layer vibration screen cloth (6,7,8) is removably fixed on vibrating shaft 10, the bottom surface of screen tray and the link position of sidewall are installed one first discharging opening 81, and the position on the sidewall of screen tray between Multilayer vibrating screen net is provided with the second discharging opening (61,71).

As shown in Figure 1, in the present embodiment, the first discharging opening and the second discharging opening are provided with the valve switch (62,72,82) of controlling discharging, for opening as required or close corresponding discharging opening, control the work of the first or second discharging opening.Valve switch (62,72,82) can be mechanical switch, or electric actuation switch.

Preferably, multi-layer vibration screen cloth (6,7,8) according to barrel hole size along the descending from top to bottom of described vibrating shaft.Motor 4 is AC induction motor.

In sum, vibratory sieve of the present utility model by arranging the second discharging opening between multi-layer vibration screen cloth, operating personnel can first be got rid of the residue on corresponding vibration screen or material aspect in needs, and then taking-up vibration screen, easy to use, and prevent spilling or leaking down of material, and cause waste and inconvenience, improve replacing, R and M work.

Although the utility model discloses as above with preferred embodiment, so it is not in order to limit the utility model.Under the utility model, in technical field, have and conventionally know the knowledgeable, not departing from spirit and scope of the present utility model, when being used for a variety of modifications and variations.Therefore, protection domain of the present utility model is when being as the criterion depending on claims person of defining.
