Abstract
The utility model discloses an oval airflow straight line screen comprising an upper screen body. The bottom of the upper screen body is supported on a support frame by an elastic device; the bottom of the upper screen body is inserted in the support frame and is connected with a vibration excitation source and the base of the vibration excitation source; the upper screen body is provided with a feed inlet, a discharging opening, a negative pressure airflow inlet and a negative pressure airflow outlet; rubber cushions and locking binding rings are arranged between the mesh layers. The utility model is characterized in that the base of the vibration excitation source is provided with at least three adjustable angles; the upper screen body is rolled into the shape of ellipse. The vibration excitation source of the utility model can change the size of the exciting force and the throwing angle by regulating the angle to obtain the screening precision and yield of the requirements. As the screen body adopts the shape of ellipse, the seal effect can be increased, and the inner leakage of the material is avoided. The adoption of two negative pressure airflow inlets and one outlet enhances the net passing rate and the screening efficiency due to the effects of the resultant force of the self weight and the negative pressure airflow.
Description
Technical field:
The utility model relates to vibrating machine, particularly a kind of oval air-flow straight line shaker with negative-pressure air-flow, angle adjustable exciting source(-)holder and the common combination of hermetically-sealed construction.
Background technology:
Present straight line shaker structure is that last sieve nest is the dull and stereotyped cuboid that is welded, and adopts the bolt fastening sealing between the rack.Pass to sieve nest by leading the exciting force that the body that shakes sends exciting source during work, make sieve nest produce vibration by elastic device material is sieved.The angle and the weight of the last lower heavy punch that the size of exciting force can only be by adjusting exciting source during screening change the material screening situation and the speed of service.The problem that this straight line shaker exists is, poor sealing performance, function singleness, and during screening material to cross the net rate undesirable, easily cause in the dust and leak and network blocking, influence screening efficiency and service life.
Summary of the invention:
The purpose of this utility model is a kind of screening efficiency height of design, good seal performance, leaks the oval air-flow straight line shaker of material in not understanding.
Art designs scheme of the present utility model is finished as follows, it includes sieve nest, last sieve nest bottom is supported on the support by elastic device, last sieve nest bottom is inserted in the support downwards and is connected with an exciting source and base thereof, last sieve nest is provided with charging and discharging mouth and negative-pressure air-flow import and export, between sieve compartment and the layer rubber cushion and lock sealing beam ring are arranged, it is characterized in that: have three angle adjustables on the exciting source base at least, last sieve nest is the rolling ellipse that forms.Last sieve nest is provided with two negative-pressure air-flow imports and an outlet, and exciting source of the present utility model can in time change the size and the parabolic angle of exciting force by angle adjustment, meets the requirements of screening precision and output; Sieve nest adopts ellipse can improve sealing effectiveness, stops to leak in the material; Adopt two negative-pressure air-flow imports and an outlet material under the influence of making a concerted effort of deadweight and negative-pressure air-flow, improved network passing rate and screening efficiency.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.Among the figure, 1. negative-pressure air-flow import, 2. charging aperture, 3. discharging opening, 4. beam ring, 5. negative-pressure air-flow outlet is 6. gone up sieve nest, 7. elastic device, 8. exciting source, 9. base.
The specific embodiment:
The utility model includes sieve nest 6, last sieve nest bottom is supported on the support by elastic device 7, last sieve nest bottom is inserted in the support downwards and is connected with an exciting source 8 and base 9 thereof, last sieve nest is provided with charging aperture 2, discharging opening 3 and negative-pressure air-flow import 1, outlet 5, between sieve compartment and the layer rubber cushion and lock sealing beam ring 4 are arranged, principal character is to have three angle adjustables on exciting source base 9 at least, and last sieve nest is the rolling ellipse that forms.The utility model also can adopt two negative-pressure air-flow imports and an outlet are set on last sieve nest.Exciting source of the present utility model can in time change the size and the parabolic angle of exciting force by angle adjustment, meets the requirements of screening precision and quality, and sieve nest adopts and ovally also uses beam ring locking can improve sealing effectiveness, stops to leak in the material; Adopt two negative-pressure air-flow imports and an outlet material under the influence of making a concerted effort of deadweight and negative-pressure air-flow, improved network passing rate and screening efficiency.
