Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

Example 1

As shown in fig. 1, a classification device for realizing overflow desliming of an interference bed separator comprises a classification boundary 8 and a support, wherein the classification boundary 8 is used for cutting and separating an overflow layer, the support is used for fixing the classification boundary 8, the classification boundary 8 is positioned above the overflow boundary 9 of the overflow layer and forms a vertical gap with the overflow boundary 9 of the overflow layer, and the classification boundary 8 is cut into the overflow layer.

In particular, the reason why the upper edge of the bucket body of the disturbed bed separator (TBS) 10 naturally forms the overflow boundary 9 is that the overflow fluid flows upwards under the pushing of the upward turbulent fluid, the bucket wall of the bucket body forms a guide structure of the overflow fluid, and when the upper end boundary of the bucket wall is reached, the overflow fluid loses support and begins to overflow outwards, so that the overflow boundary 9 is defined accordingly.

In practice, the overflow fluid is pushed by the disturbance fluid, and the overflow fluid directly overflows outwards from the overflow boundary of the overflow layer, but most of the fluid also moves upwards for a certain distance just like the boiling water surface, and based on the principle, the classification boundary 8 is arranged at a certain position above the overflow boundary, the position is determined according to the particle size needing classification, the overflow part which exceeds the classification boundary 8 overflows outwards from the upper part of the classification boundary, and the overflow part which does not exceed the classification boundary overflows outwards from the vertical gap.

In this embodiment, since the classification border 8 needs to accurately separate a flow of fluid and cannot occupy excessive vertical space, the thickness of the classification border must be thin enough to be inserted into the overflow fluid by adopting a thin plate structure, and the thin plate should be a horizontal thin plate or a thin plate with a low outer part and a high inner part to ensure the outflow of the fluid.

In order to better ensure the grading effect and not influence the normal work of the separator of the interference bed, the grading boundary does not exceed the inner edge of the inner wall of the cylinder body, and the effect is optimal when the grading boundary and the inner wall are vertically kept consistent.

The bracket is mainly used for fixing the grading boundary, so the specific form of the bracket is not limited, and the bracket can be used for fixing the grading boundary on the interference bed sorting machine, and can also be used as other types of brackets.

Example 2

As shown in fig. 2, the present embodiment is different from embodiment 1 in that: the grading boundary 8 is located at the outer equal height of the overflow layer overflow boundary 9, and forms a horizontal gap with the overflow layer overflow boundary 9.

The principle of the scheme is that overflow fluid moves upwards for a distance from an overflow boundary of an overflow layer under the pushing of disturbance fluid and overflows towards the periphery due to the fact that support is lost around the overflow fluid, but in the process, the overflow fluid on an upper layer overflows with a larger radius, and the overflow fluid on a lower layer overflows with a relatively smaller radius.

The size of the gap can control the size of the graded particle size.

In this embodiment, since the classification boundary 8 does not need to insert overflow fluid for classification, the overflow fluid moves from top to bottom at the divided part, and a horizontal plate or an inclined plate without thickness requirement can be adopted to intercept the overflow fluid, and the boundary position of the plate is only required to be controlled.

Of course, the classification can also be realized by utilizing a vertical thin plate which is inserted into overflow fluid from bottom to top, and in this way, the structure form matched with the existing interference bed separator can be an annular cylindrical structure.

Example 3

In order to more conveniently separate and flow away the classified small-particle-size particles, a flow guide plate can be connected outside the classification boundary.

Example 4

The size of the interference bed separator is large, a complete grading boundary is not easy to manufacture, the grading boundary and the support are formed by surrounding a plurality of sub-grading boundaries and sub-supports, and after surrounding installation, the complete grading boundary is formed to realize grading.

Specifically, as shown in fig. 3 and 4, the sub-support is composed of two vertical plates 3, clamping grooves 4 are formed at the lower ends of the two vertical plates 3, the sub-classification boundary is a horizontal plate 1, the two ends of the horizontal plate 1 are respectively connected with the two vertical plates 3, and the inner end profile of the horizontal plate 1 is consistent with the profile of the overflow boundary 9 and is an arc edge 5.

The clamping groove 4 is used for being installed on the upper edge of the barrel wall of the disturbed bed separator 10, and the position of the clamping groove 4 has two forms, namely, the inner edge of the horizontal plate can be positioned above the upper edge of the barrel body (as shown in figure 3) or on the outer side of the position with the same height (as shown in figure 4), so that the two grading forms in the embodiment 1 and the embodiment 2 can be realized.

By adopting the clamping groove type structure, the installation and the disassembly are convenient, and the operation is easier.

Example 5

This example differs from example 4 in that: in order to adapt to different grading requirements, the horizontal plate 1 is installed on the two vertical plates 3 through a vertical adjusting structure, specifically, rows of installation holes can be designed on the two vertical plates 3, and the horizontal plate realizes height adjustment through installation at the installation holes with different heights; alternatively, as shown in fig. 5, a vertical mounting long hole 6 is formed in the vertical plate 3, and the mounting position of the horizontal plate 1 is adjusted by an adjusting bolt 7, thereby adjusting the height.

By adopting the structure, the grading of the particle size can be realized by adjusting the height of the horizontal plate 1 from the cylinder.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
