Said device is characterized in that a highly hard level is set on the ring-wall of the centrifugal plate. The utility model is simple on structure and is low-cost. The device not only can finish the film-taking of the waste grit but also can prolong the service life.

Description

Centrifugal fine granular materials removing surface device

(1), affiliated technical field

The utility model relates to a kind of mechanical reclaim equiment, particularly a kind of centrifugal regenerating device.

(2), technical background

At present, existing centrifugal fine granular materials removing surface device, in the fine granular materials such as clay-bonded sand, resin sand and water-glass sand in handling cast waste sand, the centrifugal regenerating device of general employing, it comprises into sand hopper, square chest, Ding Quan, centrifugal pan, main shaft, axle bed, machine base and engine.With water-glass sand is example, and this centrifugal regenerating device not only is difficult to remove the coverlay on the sand grain surface in regenerative process, also has following deficiency:

1), sand grains carries out collision and rubbing at a high speed at the inwall of centrifugal pan, removes the coverlay of sand grain surface, under the strong collision and rubbing of sand grains, the inwall of centrifugal pan is worn and torn easily, influence the demoulding effect, not only usually need to change, shortened service life, and made the cost of investment height.

2), centrifugal pan drives under the rotation at a high speed at engine, sand grains is in the outside impelling of effect of inertia lower edge centrifugal pan inwall, sand grains and Ding Quan bump, and make easily to decide the circle wearing and tearing, the shortening in service life.

3), meeting produces a large amount of dust in regenerative process, influences the quality of reclaimed sand.

(3), summary of the invention

The purpose of this utility model just provides a kind of simple in structure, wear-resisting, centrifugal fine granular materials removing surface device of saving cost, and it not only can finish the demoulding effect of antiquated sand grain, and increases the service life.

The purpose of this utility model is to realize that by such technical scheme it comprises into sand hopper, square chest, Ding Quan, centrifugal pan, main shaft, axle bed, machine base and engine, it is characterized in that: the centrifugal pan ring wall is provided with the high rigidity layer.

This use is novel can remove the coverlay that the fine granular materials surface is difficult to remove, as the clay-bonded sand in the cast waste sand, the coverlay on fine granular materials such as resin sand and water-glass sand surface, is like this work with water-glass sand for example the utility model: the waterglass sand grains falls into centrifugal pan from advancing sand hopper, the engine of rotation drives the centrifugal pan rotation at a high speed, the waterglass sand grains collides and rubbing on the high rigidity layer of centrifugal pan ring wall, the waterglass sand grains is in the outside impelling of effect of inertia lower edge ring wall, with fixed circle collision, the waterglass sand grains removes the carbon element film of waterglass sand grains surface coverage in collision and rubbing.In this process, the high rigidity layer is arranged on the centrifugal pan ring wall, make the waterglass sand grains in collision and rubbing, be not easy to make the centrifugal pan wearing and tearing, not only improved the demoulding effect of waterglass sand grains, also prolonged service life.In addition, many identical these can also be used the novel overlapping multistage regeneration that is combined into, improve regeneration effect, improve the quality of reclaimed sand.

Owing to adopted technique scheme, the utlity model has advantage simple in structure, wear-resisting and that save cost, it not only can finish the demoulding effect of antiquated sand grain, and increases the service life.

Description of drawings of the present utility model is as follows:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of fixed circle in the utility model;

Among the figure: 1. advance sand hopper; 2. square chest; 3. fixed circle; 4. centrifugal pan; 5. main shaft; 6. axle bed; 7. machine base; 8. engine; 9. demoulding piece; 10. regulating part; 11. boiling deduster; 12. dust removing tube; 13. blast pipe; 14. go out sandpipe; 15. door.

(5), the specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

As shown in Figure 1, this use is novel to comprise into sand hopper 1, square chest 2, enclose 3 surely, centrifugal pan 4, main shaft 5, axle bed 6, machine base 7 and engine 8, and it is characterized in that: centrifugal pan 4 ring walls are provided with the high rigidity layer.This use is novel can remove the coverlay that the fine granular materials surface is difficult to remove, as can be to cast waste sand (clay-bonded sand, resin sand and water-glass sand) surface carries out demoulding, is like this work with water-glass sand for example the utility model: the waterglass sand grains falls into centrifugal pan 4 from advancing sand hopper 1, the engine 8 of rotation drives centrifugal pan 4 rotations at a high speed, the waterglass sand grains collides and rubbing on the high rigidity layer of centrifugal pan 4 ring walls, the waterglass sand grains is in the outside impelling of effect of inertia lower edge ring wall, with enclose 3 collisions surely, the waterglass sand grains removes the carbon element film of waterglass sand grains surface coverage in collision and rubbing.In this process, on centrifugal pan 4 ring walls high rigidity layer is arranged, make the waterglass sand grains in collision and rubbing, be not easy to make centrifugal pan 4 wearing and tearing, not only improved the demoulding effect of waterglass sand grains, also prolonged service life.In addition, many identical these can also be used the novel overlapping multistage regeneration that is combined into, improve regeneration effect, improve the quality of reclaimed sand.

As shown in Figure 2, in order to improve the demoulding effect, prolongation encloses for 3 service life surely, encloses 3 inner peripheral surfaces surely and is provided with polylith high rigidity demoulding piece 9.In order to regulate the upper and lower position of deciding circle 3,, enclose surely and also be provided with regulating part 10 on 3 to obtain demoulding effect best under specified working condition.

As shown in Figure 2, decide the collision and the rubbing effect that reach best between circle 3 and impelling sand grains in order to make, the rake angle of demoulding piece 9 is the 40-60 degree.The number of demoulding piece 9 is the 15-30 piece.

As shown in Figure 1, in order to get rid of the dust after the regeneration, improve the quality of reclaimed sand, machine base 7 is provided with the boiling dust arrester, described boiling removal apparatus comprises boiling deduster 11, dust removing tube 12, blast pipe 13 and goes out sandpipe 14, boiling deduster 11 is connected with machine base 7, and an end of boiling deduster 11 communicates with blast pipe 13, the other end with go out sandpipe 14 and communicate with the deduster 11 that seethes with excitement.

As shown in Figure 1, be provided with on the square chest 2 and be convenient to the door 15 checking or keep in repair.For the ease of its internal mechanism is checked, keeped in repair, or observe the internal work situation at ordinary times, also can all the opening the door of square chest three.
