Description

Technical Field

[0001] The present invention relates to the technical field of rock crushing, and in particular to a high-efficiency oil shale crushing auxiliary device and a use method thereof. Background Art

[0002] Oil shale is a sedimentary rock with well-developed stratification. During blasting, the energy released during the blasting process is more likely to be released along the bedding direction due to its bedding structure, resulting in a flattened shape in the blasted oil shale blocks. This shape exhibits significant anisotropy in crushing. If the crushing direction is perpendicular to the flattening direction (bedding direction), the crushed blocks will be larger. If the crushing direction is parallel to the flattening direction, the oil shale will be more likely to break along the bedding direction during crushing, resulting in smaller blocks. This simplifies the crushing process and reduces crushing energy consumption.

[0003] However, there is currently no public technical solution to this problem in the oil shale crushing process. Based on this, there is an urgent need for a technical solution that can solve the bedding direction problem in the oil shale crushing process and further improve the oil shale crushing effect. Summary of the Invention

[0004] The purpose of the present invention is to provide an efficient oil shale crushing auxiliary device and a method of use, wherein the bedding direction of the oil shale block is adjusted by the movement of the grid, so that the bedding surface of the oil shale enters the jaw crusher in a direction parallel to the grid, thereby improving the crushing effect.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] The present invention provides a high-efficiency oil shale crushing auxiliary device, comprising a separation part, a connection part, and a separation inlet device which are sequentially connected;

[0007] wherein fixed grids are respectively provided in the separation portion, the connection portion, and the separation inlet device;

[0008] A movable grille adapted to the fixed grille is further provided in the separation portion;

[0009] The movable grille is adjusted to rise and fall or to swing relative to the fixed grille by a driving unit.

[0010] Furthermore, the movable grille is limitedly provided in the separation portion, and the driving portion for driving the movable grille to rise and fall or swing is one of a crank-connecting rod mechanism or a reciprocating screw mechanism;

[0011] Or / and, wherein a reserved sliding groove is provided in the separation portion to facilitate the lifting and lowering of the movable grille;

[0012] Or / and, wherein the movable grille is hingedly arranged in the separation portion and is swung by a crank-connecting rod mechanism.

[0013] Furthermore, both ends of the fixed grille arranged in the connecting portion are fixedly connected to the inner wall of the connecting portion.

[0014] Furthermore, one end of the fixed grid provided in the separation inlet device is fixed, and a gap is left at the other end.

[0015] Still further, the separation portion, the connection portion, and the end portion of the fixed grid in the separation inlet device are aligned with each other;

[0016] or / and, wherein the separation portion and the separation inlet device have equal grid spacing;

[0017] or / and, the fixed grille spacing in the connecting portion is the same as the fixed grille spacing at the junction of the separating portion and the fixed grille spacing at the junction of the separating inlet device, wherein the fixed grille spacing in the connecting portion is designed to gradually decrease from the junction of the separating portion to the junction of the separating inlet device;

[0018] Or / and, the spacing of the separation parts is determined according to the dimension of the bedding direction of the oil shale;

[0019] The spacing between the separation inlet devices is determined according to the size of the oil shale in the vertical bedding direction.

[0020] Furthermore, the number of grids in the separation portion, the connection portion and the fixed grids in the separation inlet device are all odd numbers, and the number is adapted to the size of the jaw crusher inlet.

[0021] Furthermore, it includes the following steps:

[0022] Step 1: By cooperating with the movable grid and the fixed grid in the separation part, the bedding plane of the oil shale entering the separation part is parallel to the grid direction and falls into the connecting part;

[0023] Step 2: feeding the oil shale with the bedding plane parallel to the grid direction into the connection part;

[0024] Step 3: The oil shale with the bedding plane parallel to the grid direction is sent to the jaw crusher through the separation inlet device to be fully crushed.

[0025] Compared with the existing technology, the present invention has the following beneficial technical effects: the relatively flat block shape of the oil shale after blasting can be effectively utilized in this application. Through the device of the present invention, the shape of the oil shale blocks to be crushed after movement is adjusted, so that they can enter the crusher in a shape with increased crushing degree, thereby reducing the crushed particle size of the oil shale. The present invention is mainly developed for oil shale, but it can also be applied to the crushing of rocks with a more obvious bedding structure similar to oil shale.

[0026] The reciprocating up and down motion of the movable grid in the separation device adjusts the position of the oil shale block so that its bedding plane is parallel to the grid. After passing through the connecting device and entering the separation inlet, the bedding plane of the oil shale block is aligned with the compression direction of the jaw crusher. This allows the oil shale to break along the bedding plane during the crushing process, making it easier to break into smaller pieces. This simplifies the crushing process and reduces crushing energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] This embodiment discloses an efficient oil shale crushing auxiliary device, which includes a separation part 1, a connection part 2, and a separation inlet device 3 that are sequentially connected;

[0035] A fixed grid 5 is installed in the separation part 1, the connection part 2, and the separation inlet device 3 respectively; specifically, the separation part 1, the connection part 2, and the separation inlet device 3 are all hollow structures to facilitate the installation of the fixed grid 5;

[0036] Relative to the connecting portion 2 and the separation inlet device 3, a movable grid 4 adapted to the fixed grid 5 is also installed in the separation portion 1; wherein the movable grid 4 is used to guide the oil entering the separation portion 1, specifically, to make it move upward alternately and accompanied by vibration of a certain frequency; the position of the oil shale block can be adjusted so that the direction of its bedding surface is parallel to the direction of the grid.

[0037] Specifically, the movable grille 4 can be lifted or swung relative to the fixed grille 5 by a driving unit;

[0038] like Figure 2 As shown, the movable grille 4 is limitedly installed in the separation portion 1, and the driving part for driving the movable grille 4 to rise, fall or swing is a crank connecting rod mechanism or a reciprocating screw mechanism;

[0039] When the movable grille 4 is driven to rise and fall, a reserved sliding groove is provided in the separation portion 1 to facilitate the lifting and falling of the movable grille 4, and the driving adjustment can be performed by using a crank connecting rod mechanism or a reciprocating screw mechanism;

[0040] In this embodiment, when the movable grille 4 is driven to swing relative to the fixed grille 5 , the movable grille 4 is hingedly installed in the separation portion 1 , and the swing is adjusted by a crank-connecting rod mechanism.

[0041] like Figure 3 As shown, both ends of the fixed grille 5 installed in the connecting portion 2 are fixedly connected to the inner wall of the connecting portion 2 .

[0042] like Figure 4 As shown, one end of the fixed grid 5 installed in the separation inlet device 3 is fixed, and a gap is left at the other end.

[0043] In this embodiment, the separation portion 1, the connection portion 2, and the ends of the fixed grid in the separation inlet device 3 are aligned with each other;

[0044] The grid spacings in the separation portion 1 and the separation inlet device 3 are equal;

[0045] The fixed grid spacing in the connecting portion 2 is the same as the fixed grid spacing at the junction of the separating portion 1 and the separating inlet device 3. The fixed grid spacing in the connecting portion 2 is designed to gradually decrease from the junction of the separating portion 1 to the junction of the separating inlet device 3.

[0046] Among them, it is parallel to the crushing direction, which causes the oil shale to be crushed along the bedding plane and increases the crushing degree.

[0047] The spacing of the separation parts 1 is determined according to the size of the bedding direction of the oil shale;

[0048] The spacing between the separation inlet devices 3 is determined according to the size of the oil shale in the vertical bedding direction.

[0049] The number of fixed grids in the separation part 1, the connection part 2 and the separation inlet device 3 is an odd number, which is adapted to the size of the jaw crusher inlet.

[0050] Steps to apply the above technical solution:

[0051] Step 1: By cooperating with the movable grid 4 and the fixed grid 5 in the separation part 1, the bedding plane of the oil shale entering the separation part 1 is parallel to the grid direction and falls into the connecting part 2;

[0052] Step 2: feeding the oil shale with the bedding plane parallel to the grid direction into the connection part 2;

[0053] Step 3: The oil shale with the bedding plane parallel to the grid direction is sent to the jaw crusher through the separation inlet device 3 to be fully crushed.

[0054] Example

[0055] The separation part 1 of the present application is set above the conveyor belt, and the oil shale blocks pass through the reciprocating motion of the movable grid 4 in the separation part 1. First, the movable grid 4 for the larger oil shale blocks first vibrates upward and pushes it into the gap between the grids (such as Figure 5 Then, the movable grid 4 for the smaller oil shale blocks first vibrates upwards and pushes it into the gaps between the grids (as shown in FIG. Figure 5 c). After multiple movements of the moving grid, the oil shale block is finally adjusted so that the bedding plane is parallel to the grid;

[0056] The oil shale blocks are conveyed to the connecting device via a belt conveyor. In the connecting section 2, the distance between the oil shale blocks and the grid is gradually reduced, facilitating subsequent crushing.

[0057] After passing through the connection part 2, the oil shale blocks are sent to the separation inlet device. The grid of the separation inlet device 3 is inside the jaw crusher inlet. The oil shale always keeps the bedding plane parallel to the grid in the separation inlet.

[0058] The bedding plane of the oil shale is parallel to the grid, which is also parallel to the crushing direction, so that the oil shale is crushed along the bedding plane and the crushing degree is improved.

[0059] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by persons skilled in the art shall fall within the scope of protection defined by the claims of the present invention.
