Abstract
The utility model relates to a vibrating screen, in particular to an air compressing strong vibrating screen with double rectangular beams, which belongs to screening equipment and can be widely applied to drying type mineral classifying screening in fields of coal, chemical industry, building materials and the like. The air compressing strong force vibrating screen comprises a vibrating screen box, the vibrating screen box is mounted on a support by the aid of a damping spring, the support is fixed on the ground, the vibrating screen box is provided with an air compressing system, an air compressor in the air compressing system supplies high-pressure air entering an air compressing vibration exciter by the aid of a high-pressure air pipe, the air compressing vibration exciter is fixed on the support and connected with vibration exciting beams by the aid of fixing parts, the vibrating screen box driven by reciprocating motion of a cylinder of the air compressing vibration exciter moves vertically to produce vibration amplitude, so that materials on the vibrating screen are layered and screened. Further, the materials on the surface of the vibrating screen can naturally slide downwards, so that screening is realized.
Description
Technical field
The utility model relates to a kind of vibratory sieve, is specifically related to a kind of pneumatics double square beam strong vibrating screen, belongs to screening plant, can be widely used in the mineral dry classification screening of industries such as coal, chemical industry, building materials.
Background technology
At present, for the screening of mineral dry classification, the exciting force of most of vibratory sieves provides by mechanical eccentric formula vibrator.Its major advantage is that price is low, manufacturing process is simple.But it is more to have problems: covibration 1, very easily occurs, cause sieve nest impaired, exciting beam and sieve box side plate fracture have a strong impact on machine life; 2, vibration parameters (amplitude, frequency, treating capacity) is non-adjustable, can not satisfy the job requirement under the various states; 3, exciter structure complexity, the installation and maintenance difficulty causes the work of maintenance personnel amount to strengthen, and the working time lengthening has reduced capacity utilization.
Summary of the invention
The purpose of this utility model is for overcoming the weak point of above-mentioned prior art, a kind of pneumatics double square beam strong vibrating screen is provided, it includes the vibratory sieve screen box, screen box is rack-mount by damping spring, support is fixed on the ground, described screen box has air compression system, the pressure-air that air compressor in the system provides, enter the pneumatics vibrator by high-pressure air pipe, the pneumatics vibrator is fixed on the support, and is connected with the exciting beam by retaining element, the reciprocating motion of the cylinder of pneumatics vibrator drives screen box and moves up and down, the amplitude that produces makes oversize material layering screening, and the inclination angle of compass screen surface makes material dirty naturally, thereby reaches the purpose of screening.
The utility model is realized with following technical scheme: a kind of pneumatics double square beam strong vibrating screen, the screen box of this vibratory sieve is rack-mount by damping spring, support is fixed on the ground, it is characterized in that: described screen box includes sieve plate, be fixed with the exciting beam below the screen box, the two ends left and right symmetrically is evenly equipped with the pneumatics vibrator below the exciting beam.
It is rack-mount that described screen box and ground basal plane are the inclination angle, and its inclination angle is 15～30 °.
Air compression system is made up of air compressor and high-pressure air pipe, and is furnished with electric cabinet, and the pressure-air that air compressor provides sends the pneumatics vibrator that is installed on the exciting beam to by high-pressure air pipe.
The utility model has the advantages that: this pneumatics double square beam strong vibrating screen, utilize an air compressor can drive many pneumatics vibrator excitings, can guarantee that also complete machine operates steadily, no covibration; Can realize stepless time adjustment, vibration frequency is 500～1500 times/minute scopes.Amplitude is freely adjusted according to need of work in 5～20mm scope.Can when the different disposal amount, freely adjust vibration frequency and amplitude, to reach not only economy but also can satisfy the requirement of producing needs.Can satisfy the screening job requirement under the multiple duty.And, make complete machine structure simpler owing to cancelled mechanical eccentric formula vibrator, safeguard convenient.Both reduce attendant's labour intensity, improved capacity utilization and production efficiency again.
Description of drawings
Below in conjunction with drawings and the specific embodiments the utility model is described in further detail:
Fig. 1 is the front view of the utility model structure:
Fig. 2 is the side view of the utility model structure:
Among the figure: 1, support, 2, screen box, 3, damping spring, 4, sieve plate, 5, the exciting beam, 6, high-pressure air pipe, 7, air compressor machine, 8, the pneumatics vibrator.
The specific embodiment
As shown in the figure: a kind of pneumatics double square beam strong vibrating screen, the screen box 2 of this vibratory sieve is installed on the support 1 by damping spring 3, support is fixed on the ground, it is characterized in that: described screen box includes sieve plate 4, be fixed with exciting beam 5 below the screen box, exciting beam 5 following two ends left and right symmetricallies are evenly equipped with pneumatics vibrator 8.
Described screen box 2 is the inclination angle with the ground basal plane and is installed on the support 1, and its inclination angle is 15～30 °.
Air compression system is made up of air compressor 7 and high-pressure air pipe 6, and is furnished with electric cabinet, and the pressure-air that air compressor 7 provides sends the pneumatics vibrator 8 that is installed on the exciting beam 5 to by high-pressure air pipe 6.
Reciprocating motion by the cylinder of the pneumatics vibrator of pressure-air control drives screen box 2 and sieve plate 4 up-down vibration, to support vibratory sieve work.Simultaneously, the high strength of double square exciting beam, the target that complete machine is maximized is achieved, and the screen box hop count can be 1～8 section.
