Abstract
The utility model relates to a roll shaft type vibration screen which is applied to electric power industry, coal industry, etc. The utility model is mainly composed of a motor, a transmission mechanism, a straining box body, a screen machine sealing device, etc. The equipment also comprises an eccentric sleeve which is inserted in a bearing of a transmission shaft. A screen surface is driven by the transmission shaft. Two bearing seats which are connected with the transmission shaft are positioned in a free state, and a phase difference exists in the two bearing seats. When the equipment works, the integration of the equipment does not vibrate, and only the screen surface vibrates. The equipment has the advantages of high sieving efficiency, low noise, longer life time of the screen machine and convenient maintenance, and the equipment is not easy to clog and clamp.
Description
The utility model belongs to a kind of sieving machine that is applied to industries such as electric power, coal, particularly a kind of roller type vibratory sieve.
The sieving machine type that is widely used in industries such as the metallurgical coal chemical industries of electric power mainly contains oscillatory type screen(ing) machine and roller type screen(ing) machine at present.The screening efficiency of oscillatory type screen(ing) machine is higher, and it is bigger to exert oneself.But its equipment is body vibration, and noise is big, the grating life-span short and very easily fracture, and screen box damages easily, more foreign material easy to hang on the grating, and the cleaning difficulty has increased the workload of on-the-spot maintenance and maintenance.Roller type screen(ing) machine reliable operation, operating ratio is more steady, and noise is less.But structure is huge, and cost is higher, and screening efficiency is low, and the maintenance amount is big.Moisture content of coal is big, when coal is sticking, all have stifled card phenomenon in various degree coming for these two kinds of screen(ing) machines.
The utility model provide a kind of screening efficiency height, noise little, be difficult for taking place stifled card, screen(ing) machine life-span long, safeguard and maintenance roller type vibratory sieve comparatively easily.
The roller type vibratory sieve equipment that the utility model relates to mainly is made up of several parts such as motor, transmission mechanism, screen box body and screen(ing) machine sealing devices.This equipment integral body is not vibrated, and only is the compass screen surface vibration, and compass screen surface is driven by power transmission shaft, and power transmission shaft is a d-axis, the embedded eccentric bushing of bearing (eccentric bushing is eccentric rubber spring or capacity eccentric bearing), and the bearing block that links to each other with it is in free state.One end of compass screen surface is connected with the bearing block that is in free state, rotates the other end of compass screen surface link to each other with the device that produces linear movement (device of generation linear movement can be crank block or quadric chain) with the movement locus of bearing block.Every two adjacent gratings on the compass screen surface since separately in the bearing block that links to each other eccentric rubber spring or capacity eccentric bearing difference is set, during screen(ing) machine work, there is phase difference between two adjacent gratings, the other end of two adjacent gratings links to each other with the device of two cover generation linear movements respectively, phase difference is 0 °～180 °, can adjust rational phase difference according to actual conditions.Do the relative shear campaign like this between the compass screen surface, its movement locus is similar to circular vibration.The grating material is the plug-in polyamine fat of spring steel, has quil on the grating, and in addition, the grating on the compass screen surface is distributed as at feeding end, and middle grating is higher, the reduction successively of both sides, and the cross section of compass screen surface is arch.This layout is beneficial to the screening material and rationally distributes on compass screen surface.
The roller type vibratory sieve classification that the utility model provides is effective, and partition size is below 30MM, and material moisture can reach 25%, and it is thorough to overcome general screening plant screening, often the shortcoming of stopping up.Treating capacity is big, is equivalent to 3～4 times of roller picker, and actual power consumption is 1/3～1/4 of a roller picker, is 3/4 of probability screen, and noise is lower than other sieve type.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a compass screen surface operating mechanism front view;
Fig. 2 is a compass screen surface operating mechanism vertical view;
Fig. 3 is that the A of Fig. 2 is to view;
Fig. 4 is that the I of Fig. 1 is to view;
Fig. 5 is the B-B cutaway view of Fig. 4.
Shown in Fig. 1,3,4,5, compass screen surface is driven by power transmission shaft 1, power transmission shaft 1 is a d-axis, the embedded eccentric bushing 2 of bearing, the material of eccentric bushing 2 is steel or elastic caoutchouc, also can be capacity eccentric bearing, connect by linking bond 6 between power transmission shaft 1 and the eccentric bushing 2, the eccentric bushing 2 outer rolling bearings 3 that are with, by saturating lid 4 and sealing bone 5 rolling bearing 3 is fixed and sealing, bearing block 7,8 links to each other with power transmission shaft 1 and is in free state, and there is phase difference in the difference that is provided with owing to inner eccentric bushing 2 between the bearing block 7,8.Power transmission shaft 1 is installed on the supporting seat 11, inlays rubber sleeve between the bearing outer ring of supporting seat 11 and the bearing block.Shown in Fig. 2,3, compass screen surface is made up of grating, and an end of every adjacent two gratings such as grating 9,10 links to each other with bearing block 7,8 respectively on the compass screen surface, and the other end links to each other with the device 12 of generation linear movement, phase difference is 0 °～180 °, can adjust rational phase difference according to actual conditions.
Grating on the compass screen surface is arranged as at feeding end, and middle grating is higher, the reduction successively of both sides, and the cross section of compass screen surface is arch, and the spacing between the grating can be adjusted arbitrarily.During screen(ing) machine work, power transmission shaft 1 drives eccentric bushing 2 and rotates, make bearing block 7,8 drive the grating that links to each other respectively, do reciprocating type circular motion as grating 9,10, produce the relative changing of the relative positions between the adjacent grating, when the circular motion frequency is higher, be similar to the duty of vibratory sieve, and the integral body of screen(ing) machine equipment is motionless.
