Abstract

The utility model discloses an anti-blockage linear vibrating screen. The anti-blockage linear vibrating screen is characterized in that: the anti-blockage linear vibrating screen comprises a screen body, an anti-blockage screen frame, a plurality of anti-blockage small balls, screens, a shock absorber and a vibrating motor, at least two layers of screens are arranged in the screen body, rubber observation hole covers and a belleville spring screen-tensioning mechanism are arranged on the screen body as well, the anti-blockage screen frame is arranged on the bottom of the screen body, and the anti-blockage small balls are placed in the anti-blockage screen frame; the vibrating motor is mounted on the sidewall of the screen body directly by using bolts, and both sidewalls of the screen body are connected through steel tubes. Compared with the prior art, the anti-blockage linear vibrating screen has the advantages that: since the multiple layers of polyurethane screens are arranged in the anti-blockage linear vibrating screen, the service life is long, and the anti-blockage effect is good; the flow velocity of material can be increased, and the conveying output is increased; since the anti-blockage effect is good, the anti-blockage linear vibrating screen is suitable for screening fine materials; the structure is simple and reliable, the anti-blockage linear vibrating screen is easy to maintain, and energy consumption is low; the occupied space is small, and the processing capability is high.

Description

A kind of anti-blocking linear vibrating screen

Technical field

The utility model relates to a kind of anti-blocking linear vibrating screen.

Background technology

Vibratory sieve is widely used in the industries such as sandstone production line, metallurgy, colliery, ore dressing, building materials, has extremely important status in the bulk material treatment process.Existing vibratory sieve mainly comprises: screen box, be located at the screen cloth of the single or multiple lift of screen box inside, the vibrating device that screen box is provided with drives the screen cloth vibration with screening materials carrying; Existing linear vibrating screen often is provided with and is specifically designed to the motor bridge chair that motor is installed, and the tilt and vibration sieve does not adopt and prevents in anti-blocking screen frame that anti-blocking bead from preventing that screen cloth from stopping up simultaneously.The installation of vibration bridge chair is made, and has increased the manufacture difficulty of vibratory sieve, and its structure is also more complicated simultaneously, takies larger space.The anti-clogging modes such as cleaning chain that the tilt and vibration sieve is reused, effect is not satisfactory.

The utility model content

The utility model provides a kind of anti-blocking linear vibrating screen in order to solve the above-mentioned deficiency of prior art.

Above-mentioned purpose of the present utility model realizes by following technical scheme: a kind of anti-blocking linear vibrating screen, it is characterized in that: comprise sieve nest, anti-blocking screen frame, anti-clogging bead, screen cloth, damping device and vibrating motor, be provided with two-layer at least screen cloth in described sieve nest, also be provided with rubber handhole cover and butterfly spring screen cloth strainer on described sieve nest, anti-blocking screen frame is arranged at bottom sieve nest, place some anti-blocking beads in anti-blocking screen frame, can prevent effectively that screen cloth from stopping up, and is fit to the screening of thin material; Described vibrating motor directly is installed on the sieve nest sidewall with screw, and sieve nest connects with steel tube between the two side, and described structure is compacter, takes up room little, and disposal ability is large.

Preferably, described screen cloth is skewed, and the angle of inclination is 10 ° of left and right.Described screen cloth is polyurethane screen, long service life, and anti-clogging is effective.

Preferably, be provided with handhole cover on described sieve nest, be convenient to observe screening effect and sample analysis.

The utility model advantage compared with prior art is: the built-in multilayer polyurethane screen cloth of the utility model, and long service life, blocking-proof result is good; Its screen angle is 10 ° of left and right, can strengthen the flowing velocity of material, improves and carries output; The anti-blocking screen frame of installing between the sieve nest two side and anti-blocking bead, anti-clogging is effective, is fit to the screening of thin material; Adopt two vibrating motors, motor synchronizing counter-rotating exciting drives vibratory sieve work, and is simple and reliable for structure, safeguards that simply energy consumption is low; Vibrating motor directly is installed on the sieve nest sidewall with screw, and sieve nest is used the pipe support and connection between the two side, and described structure is compacter, takes up room little, and treating capacity is large.

Description of drawings

Fig. 1 is side-looking structural representation of the present utility model;

Fig. 2 is plan structure schematic diagram of the present utility model;

Fig. 3 is the partial enlarged drawing at A place in Fig. 2.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail:

As Fig. 1, Fig. 2 and shown in Figure 3, a kind of anti-blocking linear vibrating screen, it is characterized in that: comprise sieve nest 1, anti-blocking screen frame 2, anti-clogging bead 3, screen cloth 4, damping device 5 and one group of vibrating motor 6, totally four layers of described screen clothes 4, also be provided with rubber handhole cover 7 and butterfly spring screen cloth strainer 8 on described sieve nest 1, anti-blocking screen frame 2 is arranged at sieve nest 1 bottom, places some anti-blocking beads 3 in anti-blocking screen frame 2, can prevent effectively that screen cloth from stopping up, and is fit to the screening of thin material; Described vibrating motor 6 directly is installed on sieve nest 1 sidewall with screw, connects with steel pipe 9 in the middle of sieve nest 1, and described structure is compacter, takes up room little, and disposal ability is large.

But the above-mentioned specific embodiment is exemplary, is to be this patent to be comprised the restriction of scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses do anyly be equal to change or modify, all fall into the scope that this patent comprises.
