Description

Technical Field

[0001] The utility model relates to the field of coal preparation equipment, in particular to a heavy medium cyclone equipment for clean coal separation. Background Art

[0002] Heavy medium cyclone is a device that uses centrifugal force to grade and separate by high-speed rotation. The slurry to be separated enters the cyclone under pressure or gravity to form a high-speed rotating fluid. Under the action of centrifugal force, the heavy medium is thrown to the wall of the cyclone and rotates downward to form an underflow, which is discharged from the heavy medium outlet; the light medium forms an overflow and enters the production circulation system from the light medium outlet. This separation state is also called solid-liquid phase separation.

[0003] The current heavy medium cyclone basically forms a swirl through the initial angle and speed of the slurry when it enters the tank. However, the movement speed of the slurry in the conventional cyclone is relatively slow, which makes the heavy medium discharge process longer and affects the overall coal preparation efficiency.

Therefore, the above terms should not be understood as limiting the present invention.

[0019] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0020] like Figure 1-2 The utility model provides a heavy medium cyclone device for clean coal separation, comprising a tank body 1, a heavy medium outlet 2 arranged at one end of the tank body 1, a light medium outlet 3 arranged at the other end of the tank body 1, and a feed port 4 arranged on one side of the tank body 1, the axis of the heavy medium outlet 2 and the axis of the light medium outlet 3 are collinearly arranged, a guide plate 5 is arranged at a position near the feed port 4 inside the tank body 1, and the guide plate 5 is close to the inner wall of the tank body 1 and is distributed in a spiral shape.

[0021] The slurry is poured from the feed port 4 in a tangential direction so that the slurry contacts the inner wall of the tank body 1 and rotates along the inside of the tank body 1. At this time, the slurry contacts the guide plate 5. The guide plate 5 is distributed in a spiral shape so that the guide plate 5 guides the flow direction of the slurry, thereby forming a swirl flow along the guide plate 5 of the spiral section 2, so as to increase the speed and angle of the swirl flow, thereby assisting in improving the efficiency of heavy medium discharge to the heavy medium outlet 2. At the same time, since the guide plate 5 is conducive to the generation of swirl flow, the light medium and the heavy medium are easier to separate, thereby improving the effect and efficiency of light medium discharge from the light medium outlet 3.

[0022] Among them, the feeding direction of the feed port 4 is toward the tangent direction of the inner wall of the tank body 1, so as to ensure that after the slurry enters the tank body 1, it can move along the tangent of the inner wall of the tank body 1, thereby forming a vortex; the height of the heavy medium outlet 2 is lower than the height of the light medium outlet 3, so as to ensure that the heavy medium is discharged with the vortex.

[0023] It is worth mentioning that the heavy medium cyclone equipment used in the clean coal separation of this scheme has a basic operating principle that is consistent with the existing heavy medium cyclone equipment, that is, when the slurry enters along the tangential direction of the inner wall of the tank body 1, the initial velocity of the slurry when entering the tank body 1 provides power, so that the slurry generates a cyclone along the inner wall of the tank body 1. At this time, according to the Archimedes principle, the slurry will simultaneously form two spiral flows during the cyclone process, and there is a zero-speed envelope surface between the two spiral flows. The light medium can penetrate through the zero-speed envelope surface and enter the inner spiral flow, so that the heavy medium is discharged from the heavy medium outlet 2 along the outer spiral flow, and the light medium is discharged from the light medium outlet 3 along the inner spiral flow.

[0024] Preferably, a retaining ring 6 is extended from one end of the light medium outlet 3 close to the tank body 1 , the retaining ring 6 is placed inside the tank body 1 and is sealed with the tank body 1 , and the guide plate 5 is connected to the retaining ring 6 .

[0025] Specifically, the sealing cooperation between the retaining ring 6 and the tank body 1 improves the light medium discharge effect at the light medium outlet 3 , and at the same time, since the guide plate 5 is connected to the retaining ring 6 , the stability of the guide plate 5 during use is further improved.

[0026] Preferably, the tank body 1 includes a main tank body 7 and a sub-tank body 8, the main tank body 7 and the sub-tank body 8 are detachably connected, and the light medium outlet 3 is placed into the tank body 1 through the connection between the main tank body 7 and the sub-tank body 8.

[0027] Specifically, since the main tank body 7 and the auxiliary tank body 8 can be disassembled from each other, the light medium outlet 3 and the retaining ring 6 can be placed or detached from the disassembly position, thereby improving the convenience of maintenance and replacement of the retaining ring 6 and the guide plate 5.

[0028] In one embodiment of the present solution, a sealing ring is provided at the connection between the main tank body 7 and the auxiliary tank body 8 to ensure the sealing effect of the inner wall of the tank body 1 .

[0029] Preferably, the outer side of the main tank body 7 and the outer side of the auxiliary tank body 8 are connected by a connecting rod 9, and a first support rod 10 is rotatably installed on one end of the connecting rod 9, and a second support rod 11 is rotatably installed on the other end, and a connecting rod 12 is arranged between the bottom end of the first support rod 10 and the top end of the second support rod 11, and the connecting rod 12 and the first support rod 10, and the connecting rod 12 and the second support rod 11 are all hingedly arranged.

[0030] Specifically, the main tank body 7 and the outer side of the auxiliary tank body 8 are fastened together by the connecting rod 9 to ensure the structural stability of the tank body 1 during use. At the same time, the two ends of the connecting rod 9 are supported by the first support rod 10 and the second support rod 11 respectively, and then the two ends of the outer side of the tank body 1 are supported. Due to the setting of the connecting rod 12 structure, when the first support rod 10 is against the ground, the inclination angle of the connecting rod 9 relative to the ground can be easily adjusted by rotating the second support rod 11 and the connecting rod 12, and then the inclination angle of the tank body 1 can be easily adjusted to adapt to different ground conditions.

[0031] The connecting pipe is fastened to the main tank body 7 and the auxiliary tank body 8 by bolts.

[0032] Preferably, a telescopic rod 13 is connected between the second support rod 11 and the connecting rod 12 , and two ends of the telescopic rod 13 are hinged to the second support rod 11 and the connecting rod 12 respectively.

[0033] Specifically, when the second support rod 11 and the connecting rod 12 are rotated to adjust the inclination angle of the tank body 1, the angle between the second support rod 11 and the connecting rod 12 will change synchronously. At this time, by adjusting the length of the telescopic rod 13 and positioning the length of the telescopic rod 13, the relative positions of the second support rod 11 and the connecting rod 12 can be determined, thereby stably controlling the inclination angle of the tank body 1 after adjustment.

[0034] Preferably, the telescopic rod 13 includes an outer tube 14 and an inner tube 15, the inner tube 15 is provided with a plurality of positioning holes 16 along the axial direction, the outer tube 14 is provided with an insertion hole 17, and a positioning pin 18 enters from the insertion hole 17 and is plugged into any positioning hole 16 to fix the outer tube 14 and the inner tube 15.

[0035] Specifically, when positioning the length of the telescopic rod 13, the outer tube 14 and the inner tube 15 are first moved and adjusted to a suitable position, and then the positioning pin 18 is inserted from the socket 17 and simultaneously inserted into the positioning hole 16 currently corresponding to the socket 17, so that the positioning pin 18 positions the relative position of the inner tube 15 and the outer tube 14, thereby stably controlling the length of the telescopic rod 13.

[0036] Preferably, a vertical rod 19 is provided at the connection between the second support rod 11 and the connecting rod 9, and an infrared emitter 20 is rotatably installed at the bottom end of the vertical rod 19. A light guide plate 21 is provided on the outer side of the first support rod 10, and a light guide hole 22 is opened on the light guide plate 21, and the distance from the connection between the first support rod 10 and the connecting rod 9 to the light guide hole 22 is equal to the length of the vertical rod 19.

[0037] Specifically, when adjusting the inclination angle of the tank body 1, the vertical rod 19 is placed perpendicular to the ground, and at the current position of the vertical rod 19, the infrared emitter 20 is aligned with the light guide plate 21 for irradiation, and the irradiation position of the infrared emitter 20 is gradually adjusted until the infrared light passes through the light guide hole 22. At this time, the position of the ground irradiated by the infrared emitter 20 is the first marking point, and then the infrared emitter 20 is placed with the vertical rod 19, so that the infrared emitter 20 forms a second marking point when irradiating the ground, and the length x from the infrared emitter 20 to the ground can be calculated, and at the same time, the length x can be calculated. The length y between the first marking point and the second marking point is obtained. Since the vertical rod 19 is arranged perpendicular to the placement ground, and the distance from the connection point of the first support rod 10 and the connecting rod 9 to the light guide hole 22 is equal to the length of the vertical rod 19 (that is, the line connecting the infrared emitter 20 and the catheter hole is parallel to the connecting rod 9), there is a right angle between x and y. In the right triangle, the length of the third side can be obtained by knowing the length of the two sides x and y, and then the angle between the third side and the placement ground is calculated. The angle is the inclination angle of the connecting rod 9 relative to the placement ground, and then the inclination angle of the tank body 1 can be accurately known.

[0038] Preferably, a plurality of lifting ears 23 are provided on the outer side of the tank body 1 .

[0039] Specifically, by providing the lifting lug 23 , the tank body 1 can be lifted and lowered by a crane or other equipment, thereby improving the convenience of installing the tank body 1 .
