Description

A kind of screen frame that revolves the sieve that shakes

One, technical field: the utility model relates to a kind of vibratory equipment, particularly a kind of screen frame that revolves the sieve that shakes.

Two, background technology: the known sieve that shakes that revolves, for the screen cloth in the screen frame is tightened, in the screen frame body, be provided with and press down the net circle, the annular surface that presses down the net circle is provided with the ring-type v-depression, the ring-type V-arrangement convex surface that last v-depression of pressing the lower surface of netting circle to be provided with and to press down the net circle matches, screen cloth is placed on and presses down between the net circle, by on the bolt that presses down on the net circle screen cloth is tightened, on the bolt that presses down below the net circle, be provided with cushion cover and sieve grate, sieve grate is provided with isolates skin and bounder, this screen frame structure has following shortcoming: it is bigger to go up lower clamping ring weight, when the number of plies of screen frame more for a long time, the top-heavy phenomenon of equipment appears, the equipment job insecurity, influence screening efficiency, consumed power is big; V-shaped groove precision prescribed height, technology cost height when its machining accuracy is low, can cause the screen cloth unbalance stress, influences screen cloth service life; When the maintain and replace screen cloth, need screw off earlier between sieve lid and underframe behind the connecting bolt, also need screw off the bolt in the screen frame and could change screen cloth, load and unload complexity.

Three, summary of the invention: technical problem to be solved in the utility model is, a kind of screen frame is provided, and it is simple in structure, and is in light weight, convenient disassembly.The technical solution of the utility model is, this screen frame that revolves the sieve that shakes include screen frame body, screen cloth, sieve grate and on isolation skin and bounder, it is characterized in that: the sticking net circle of ring pipe that a square-section is arranged, screen cloth places on the sticking adhesive layer of netting on the annular surface that encloses, the sieve grate of sticking net circle and below thereof places down on the annular endplate of screen frame, and the annular endplate of last screen frame places on the sticking net circle.The upper surface of screen cloth and the upper and lower surface of sieve grate are respectively equipped with Gask-O-Seal.Owing to adopted ring pipe glue the net coil structures, replaced weight big on press down the net circle, thereby the utlity model has in light weightly, the working stability power consumption is few, dismantles easyly, has saved the advantage of keeping in repair the downtime of draping.

Four, description of drawings: Fig. 1 is a structural representation of the present utility model; Fig. 2 is the partial enlarged drawing of Fig. 1.Among the figure, 1. 5. times screen frame bodies of top sieve framework 2. sealing gaskets, 3. sticking net circle 4. sealing gaskets, 6. sieve grates, 7. bounders 8. are isolated skin 9. screen clothes

Five, the specific embodiment: the screen frame that revolves the sieve that shakes of the present utility model, its screen frame body is top sieve framework 1 and following screen frame body 5, the screen frame body is a cylinder up and down, there is an annular endplate at its two ends, sticking net circle 3 is the ring pipe of a square-section, and its axial height should be lower than the jumping height of the bounder on the sieve grate.The assembly method of this screen cloth frame is, at first the pipe with the square-section curves an annulus, alignment from beginning to end is also fixing, with the net instrument that stretches tight (as be provided with V-shaped groove on press down net circle) screen cloth 9 is tightened, upper surface at sticking net circle is coated with one deck glue, the screen cloth of tightening is placed on the sticking net circle together with the net instrument that stretches tight, on the screen cloth on the annular surface of sticking net circle, put an annular sponge sealing gasket 2, then to screen cloth on the sticking net circle and the pressurization of sponge sealing gasket, treat to finish pressurization behind the curable adhesive layer, the dismounting net instrument that stretches tight is cut the outer unnecessary screen cloth of sticking net circle, has promptly finished the sticking net work of sticking net circle.Isolation skin 8, bounder 7 are placed on down on the annular endplate of screen frame body 5 after being assembled on the sieve grate, the upper and lower surface of sieve grate is provided with elastic ring sealing gasket 4, the sticking net circle 3 that glues screen cloth 9 is placed on the sieve grate, again last screen frame 1 is placed on the sponge sealing gasket 2 of sticking net circle, after the assembling of each layer screen frame finishes, bolt on top layer screen frame and the bottom screen frame is screwed, at this moment, the viscous force of the existing adhesive layer of screen cloth on each sticking net circle, bigger axial compressive force is arranged again, thereby have than the bigger and more uniform intensity of existing V-shaped groove pressure net circle.Owing to the sticking net work of sticking net circle can be carried out in advance, therefore, adopt this screen cloth frame, when changing screen cloth, have fast, the advantage that shortens downtime only need be screwed the bolt between top screen frame and end screen frame, has saved the bolt of screwing in the screen frame.

Claims (2)

1, a kind of screen frame that revolves the sieve that shakes, it include screen frame body, screen cloth, sieve grate and on isolation skin and bounder, it is characterized in that: the sticking net circle of ring pipe that a square-section is arranged, screen cloth places on the sticking adhesive layer of netting on the annular surface that encloses, the sieve grate of sticking net circle and below thereof places down on the annular endplate of screen frame, and the annular endplate of last screen frame places on the sticking net circle.

2, a kind of screen frame that revolves the sieve that shakes according to claim 1, it is characterized in that: the upper surface of screen cloth and the upper and lower surface of sieve grate are respectively equipped with Gask-O-Seal.
