Description

Technical Field

[0001] The present invention relates to an impurity sorting and separating machine, in particular to the technical field of impurity screening. Background Art

[0002] A separating machine, also known as a purifying machine or a screening machine, is used to screen out grain impurities. In the fields of agricultural product processing, mining sorting, food processing, etc., a screening machine is a core device for separating impurities of different particle sizes or classifying materials; traditional screening machines usually use a sieve mesh with a fixed aperture, which is difficult to meet the requirements of different impurity sorting, especially when dealing with materials with high water content and high viscosity, the sieve mesh is prone to clogging and the sorting efficiency is low.

[0003] The aperture of the sieve mesh of traditional screening machines is fixed. When processing materials with more impurities, clogging is likely to occur, resulting in a decrease in screening efficiency; although some devices alleviate the clogging problem by increasing the vibration frequency or adjusting the amplitude, the effect is limited;

[0004] Many screening machines need to frequently replace the sieve mesh or adjust the equipment parameters to adapt to different materials, increasing the operation difficulty and maintenance cost. In addition, some devices lack a convenient disassembly and cleaning design, further affecting the work efficiency;

[0005] Existing screening machines are mostly single-function devices and cannot meet the screening requirements of multiple materials at the same time; for example, in grain processing, it is necessary to remove large impurities first and then perform fine screening, while existing devices are difficult to take both of these requirements into account.

[0033] The following further specifically describes this solution through examples and in conjunction with the accompanying drawings.

[0034] In the present application, an impurity separation and classification machine is proposed, including:

[0035] Support 1, shock absorber 2 arranged above support 1, vibration chamber 3 arranged above shock absorber 2, screening chamber 4 arranged above the vibration chamber 3, and cover plate 5 arranged above the screening chamber 4; at least four shock absorbers 2 are provided and are distributed at the diagonals of the support 1, one end of the shock absorber 2 is fixedly connected to the support 1 and the other end is fixedly connected to the vibration chamber 3; a buckle 31 for disassembling the vibration chamber 3 is provided between the vibration chamber 3 and the screening chamber 4; the cover plate 5 is detachably connected to the screening chamber 4, and an opening communicating with the feed pipe 10 is formed on the cover plate 5.

[0036] An inner cylinder 6 and an outer cylinder 7 sleeved outside the inner cylinder 6 are arranged in the screening chamber 4. The inner cylinder 6 is in circumferential rotational fit with the screening chamber 4, and the outer cylinder 7 is in axial movement fit with the inner cylinder 6; a waste discharge port is arranged at the end of the inner cylinder 6, and the waste discharge port is located at the end of the direction in which the stirring blade 42 pushes the material. The inner cylinder 6 and the outer cylinder 7 are both provided with U-shaped holes 8 for separating impurities. A limiting hole 71 is formed in the outer cylinder 7, and a positioning pin 72 fixed on the inner cylinder 6 is arranged in the limiting hole 71. One end of the inner cylinder 6 is provided with a return spring 9 connected to the outer cylinder 7. A plurality of return springs 9 are provided and both ends are connected to the inner cylinder 6 and the outer cylinder 7. The other end of the inner cylinder 6 is provided with a setscrew 61 for adjusting the displacement of the outer cylinder 7; a plurality of setscrews 61 are provided, one end of which is in threaded fit with the inner cylinder 6 and the other end contacts and pushes the outer cylinder 7.

[0037] The first end of the inner cylinder 6 is provided with a feed pipe 10. The feed pipe 10 is sleeved on the rotating shaft and is in rotational sealing fit with the rotating shaft and the inner cylinder 6; the rotating shaft is in interference fit with the inner cylinder 6 and is in circumferential rotational fit with the screening chamber 4; the feed pipe 10 communicates with a feed port 62 formed in the inner cylinder 6. A screen 33 is arranged in the vibration chamber 3 and below the outer cylinder 7; the screen 33 and the vibration chamber 3 are provided with non-communicating discharge ports 34 at the same end. The screen 33 is connected to the vibration chamber 3 through an elastic support, and a vibration motor 32 is arranged at the bottom of the outer wall of the vibration chamber 3.

[0038] A stirring blade 42 is arranged in the middle of the inner cylinder 6. The rotating shaft of the stirring blade 42 sequentially passes through the inner cylinder 6, the feed pipe 10 and the screening chamber 4, and a rotating motor 41 for driving the rotating shaft to rotate is arranged on one side of the screening chamber 4.

[0039] Working principle: First, the U-shaped holes 8 of the inner cylinder 6 and the outer cylinder 7 are completely aligned. At this time, the screening aperture is the largest, which is suitable for the rapid screening of larger particle materials; the return spring 9 is in a natural extended state, and the outer cylinder 7 has no axial displacement;

[0040] When the aperture needs to be adjusted, the operator rotates the top screw 61 (adjusting bolt) to push the outer cylinder 7 to move axially. The outer cylinder 7 moves so that its U-shaped hole 8 gradually staggers with the U-shaped hole 8 of the inner cylinder 6, the overlapping part is reduced, and the effective screening aperture becomes smaller; the limiting hole 71 of the outer cylinder 7 cooperates with the positioning pin 72 of the inner cylinder 6 to ensure that the outer cylinder 7 only moves axially to avoid rotational deviation; when the outer cylinder 7 moves, the reset spring 9 is compressed to store the rebound force for subsequent reset;

[0041] When the U-shaped hole 8 is displaced to the required screening size, stop adjusting the top screw 61. At this time, the position of the outer cylinder 7 is fixed, the screening aperture is stable, and the elastic force of the return spring 9 is balanced with the locking force of the top screw 61 to prevent the outer cylinder 7 from being displaced due to vibration.

[0042] When it is necessary to reset to the initial state, the top screw 61 is rotated in the reverse direction to reduce the pressure on the outer cylinder 7. Under the action of the spring 9, the outer cylinder 7 automatically returns to its original position, and the U-shaped hole 8 is realigned to restore the maximum screening aperture;

[0043] During the first-stage filtration, the material enters from the opening of the cover plate 5 and falls into the inner tube 6 through the feed pipe 10; the rotating motor 41 drives the stirring blade 42 and the inner tube to move the large particles of impurities that have not passed through the U-shaped hole 8 along the axial direction of the inner tube 6; after the impurities are pushed to the end of the inner tube 6, they are discharged from the impurity discharge port to the independent impurity collection tank (physically isolated from the finished product discharge port 34); qualified materials (particle size is smaller than the size of the U-shaped hole 8) fall from the gap between the inner and outer tubes 7 and enter the vibration chamber 3;

[0044] During secondary filtration, the material that passes through the primary screening falls onto the screen 33 of the vibration chamber 3, and the vibration motor 32 causes the vibration chamber 3 and the screen 33 to vibrate; fine particles (such as dust and debris) pass through the screen 33 and are discharged from the discharge port 34 at the bottom of the vibration chamber 3; the finished material (medium particle size) slides along the surface of the screen 33 and is collected from the side discharge port 34.

[0045] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and details may be made without departing from the spirit and scope of the present invention as defined in the appended claims.
