Description
Technical field
The utility model relates to a kind of vibratory sieve, be specifically related to a kind of can the vibratory sieve of classification.
Background technology
In a lot of fields such as medicine, need to use vibratory sieve by material screening, the object of screening is to remove a small amount of impurity on the one hand, on the other hand material is classified according to size, so that better deep processing material.Common vibratory sieve is primarily of vibrating mechanism, screen frame composition, and screen frame is divided into upper and lower multilayer, is connected between screen frame and is connected by beam ring, screen frame is fixed with screen cloth, the aperture of screen cloth reduces gradually from top to bottom, make material fall process according to size fractionation, flow down from corresponding discharging opening.
This kind of screening plant has elastic sphere at screen cloth, elastic sphere bob when vibrating mechanism work, applies active force, make sieved through sieve material to screen cloth.Existing major defect is: 1. screen cloth needs frequent replacing, and most screen cloth is fixed on screen frame, cumbersome when replacing; 2. when screening, material is easily reunited, and makes screening effect not obvious.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of dust-proof grading oscillating screen, can prevent dust from flying, material is separated according to granule size.
The technical solution of the utility model is achieved in that a kind of dust-proof grading oscillating screen, comprise bearing, vibrating motor is provided with in bearing, screening plant is provided with above bearing, screening plant is connected with blanking mouth, described screening plant comprises screening plant and screening plant under at least one, be connected by band between upper screening plant and lower screening plant, described upper screening plant comprises upper frame, upper frame top is connected with dust cap, dust cap is connected with feeding cylinder, upper frame bottom is provided with screen cloth, described lower screening plant comprises underframe, underframe top is provided with punched-plate, punched-plate is fixed with circular limitting casing, bounder is provided with in limitting casing, screen cloth is provided with bottom underframe.
Upper frame and underframe inwall are fixed with a circle screen cloth Connection Block, and screen cloth is connected with screen cloth Connection Block by bolt.
Described lower screening plant is two or three.
Described blanking mouth one end is by gemel connection on upper frame, and the other end is connected on upper frame by pin.
In the utility model, dust cap can make screening process be in air-tight state, prevents dust of kicking up, and limitting casing can prevent bounder from assembling, make bounder apply active force to screen cloth uniformly, screen cloth service life can be extended on the one hand, screening can be made on the other hand more thorough.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is screening plant structural representation.
Wherein: 1. bearing, 2. descend screening plant, 2-1. underframe, 2-2. punched-plate, 2-3. elastic ball, 2-4. limitting casing, 3. band, 4. go up screening plant, 4-1. upper frame, 4-2. dust cap, 4-3. feeding cylinder, 5. blanking mouth, 6. screen cloth, 7. screen cloth Connection Block.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not paying the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As illustrated in fig. 1 and 2, a kind of dust-proof grading oscillating screen, comprise bearing 1, vibrating motor is provided with in bearing 1, screening plant is provided with above bearing 1, screening plant is connected with blanking mouth 5, described screening plant comprises screening plant 4 and lower screening plant 2, be connected by band 3 between upper screening plant 4 and lower screening plant 2, described upper screening plant 4 comprises upper frame 4-1, upper frame 4-1 top is connected with dust cap 4-2, dust cap 4-2 is connected with feeding cylinder 4-3, upper frame 4-1 bottom is provided with screen cloth 6, described lower screening plant comprises underframe 2-1, underframe 2-1 top is provided with punched-plate 2-2, punched-plate 2-2 is fixed with circular limitting casing 2-4, bounder 2-3 is provided with in limitting casing 2-4, screen cloth 6 is provided with bottom underframe 2-1.Described lower screening plant 2 be two or three or more, can arrange as required.
Utility model works process is as follows: material falls into upper screening plant from feeding cylinder 4-3, vibrating motor work strip dynamic elasticity ball 2-3 bob, elastic ball 2-3 applies active force to screen cloth 6, material is sieved, the material that particle is larger is discharged through corresponding blanking mouth, and the material that particle is less falls on next stage screen cloth.(limitting casing and punched-plate are all circular punched-plate 2-2 to be fixed with multi-turn limitting casing, its center of circle is identical, limitting casing is distributed on punched-plate gradually according to diameter change), elastic ball is distributed in different limitting casing 2-4, in spring process up and down, elastic ball can not be assembled, relatively more even to the active force of screen cloth 6, makes screen cloth elongated for service life.In vibratory sieve, screen cloth holds flimsy object most, in the utility model, limitting casing is fixed on punched-plate 2-2, when replacing screen cloth, do not need adjustment punched-plate or limitting casing, operate simpler and easy, and limitting casing can mesh support screen 6 to a certain extent, extends the service life of screen cloth further.All closed state is in, can not kick up dust or dry bits in whole process.
Preferably, upper frame 4-1 and underframe 2-1 inwall are fixed with a circle screen cloth Connection Block 7, and screen cloth 6 is connected with screen cloth Connection Block 7 by bolt.Such setting is for the ease of changing screen cloth.
In order to prevent the too fast blanking mouth 5 that causes of blanking from blocking, affect normal discharge, the utility model by blanking mouth 5 one end by gemel connection on upper frame 4-1, the other end is connected on upper frame 4-1 by pin.If run into clogging, can pin be removed, open blanking mouth 5, blocking material is removed.Blanking mouth is adopted with underframe and is connected in the same way.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
