Description

Technical Field

[0001] The utility model relates to the technical field of centrifuge material layer control, in particular to a horizontal siphon centrifuge. Background Art

[0002] A centrifuge is an industrial device that uses centrifugal force to accelerate the separation of substances. This force is generated by high-speed rotation, and its magnitude is proportional to the substance's radius of rotation, its mass, and the square of its rotational speed. Because substances of different densities experience different centrifugal forces, heavier particles or denser substances are pushed to the bottom of the centrifuge tube, while lighter or less dense substances remain in the upper layer or near the center. This allows for the separation of suspensions of immiscible liquids and solid particles of varying densities.

[0003] In the prior art, during the use of a horizontal siphon centrifuge, solid matter generated after the material is separated by the drum will enter the solid collection chamber of the casing and adhere to the inner wall of the solid collection chamber. After the centrifuge has been working for a long time, it is easy for there to be too much solid matter in the casing but it is difficult to detect and deal with it in time, so that a large amount of material is likely to enter the drum and it is difficult to discharge the solid matter generated by the separation into the solid collection chamber, which easily causes the material to accumulate in the drum. In this way, on the one hand, due to the excessive accumulation of material in the drum and the casing, it is easy to cause the internal parts of the centrifuge to be blocked, which easily causes equipment failure; on the other hand, it is difficult to discharge a large amount of material in the drum in time, which easily makes it difficult for the drum to effectively separate the material, resulting in the problem of unqualified moisture content of some materials after separation, thereby causing unnecessary economic losses.

[0023] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] like Figure 2 and Figure 4As shown, an embodiment of the present invention provides a horizontal siphon centrifuge. The horizontal siphon centrifuge includes a frame 1; a housing 39 disposed on the frame 1, the housing 39 having a first chamber 26 and a second chamber 27 that are isolated from each other; a centrifuge body having a separation chamber 40, a feed port 8, a solid outlet 22, and a liquid outlet 23 that are connected to the separation chamber 40, the solid outlet 22 being connected to the first chamber 26, and the liquid outlet 23 being connected to the second chamber 27. A feed valve is provided at the feed port 8 for controlling the entry of material, and the material undergoes solid-liquid separation in the separation chamber 40; and a material control mechanism including a detection member 35 and a switch member 11. The detection member 35 is used to sense the thickness of the material layer. The switch member 11 is linked to the detection member 35 and is controllably connected to the feed valve to control the feed of the feed valve.

[0025] In the above technical solution, the feed valve is opened, and pressure is used to force the material to be separated into the separation chamber 40 through the feed port 8, so that the material is separated into solids and liquids in the separation chamber 40 under the action of centrifugal force. The liquid enters the second chamber 27 through the liquid outlet 23, and the solid enters the first chamber 26 through the solid outlet 22 and adheres to the inner wall surface of the first chamber 26. When the solids in the first chamber 26 accumulate too much, the detection component can sense it in time and drive the switch component 11 to close the feed valve in time, thereby avoiding continuous feeding into the separation chamber 40, thereby avoiding the problem of excessive accumulation of material in the separation chamber 40 due to the difficulty of the material in the separation chamber 40 being discharged into the first chamber 26 in time. In this way, on the one hand, the probability of blockage inside the horizontal siphon centrifuge can be reduced, thereby reducing the probability of failure of the horizontal centrifuge; on the other hand, the solid-liquid separation of the material in the separation chamber 40 can be effectively performed, thereby avoiding the phenomenon of unqualified moisture content of the material, thereby avoiding unnecessary economic losses.

[0026] It should be noted that, in the embodiment of the present invention, the material fed into the feed port 8 is lithium carbonate mother liquor, which forms solid lithium carbonate and liquid after solid-liquid separation.

[0027] It should be noted that in the embodiment of the present invention, the feed valve is a pneumatic ball valve, which mainly includes components such as a valve body, a valve core, and a pneumatic actuator. Generally, compressed air is provided by an air compressor to drive the pneumatic actuator to generate movement, and the pneumatic actuator pushes the valve core of the ball valve to achieve the opening and closing operation, thereby realizing the opening or closing of the valve feed valve. The specific structure of the feed valve can refer to the existing technology and will not be described in detail here. Specifically, the switch component 11 is connected to the air compressor through a controller to drive the pneumatic ball valve to close.

[0028] like Figure 2 and Figure 4As shown, in the embodiment of the present invention, the switch component 11 is installed on the housing 39, and the detection component includes: a connecting body 9, which is rotatably connected to the housing 39; a detection claw 10, which is fixedly connected to the connecting body 9, and the detection claw 10 extends into the first chamber 26 and is spaced apart from the inner wall of the first chamber 26; a pressing claw 28, which is fixedly connected to the connecting body 9, and along the axis of the housing 39, the pressing claw 28 and the detection claw 10 are respectively located on opposite sides of the connecting body 9, and the pressing claw 28 abuts against the pressing part of the switch component 11.

[0029] Through the above arrangement, when the solid lithium carbonate in the first chamber 26 reaches a set amount, that is, when the solid lithium carbonate on the inner wall surface of the first chamber 26 reaches a set thickness, Figure 4 The solid lithium carbonate in the centrifuge presses the detection claw 10 to move upward. At this time, the connecting body 9 rotates clockwise to drive the pressing claw 28 to move downward, pressing the pressing part of the switch component 11, so that the switch component 11 controls the feed valve to close. In this way, the content of lithium carbonate mother liquor in the horizontal siphon centrifuge can be controlled to prevent excessive accumulation of lithium carbonate mother liquor. In this way, not only can the problem of clogging of internal parts of the horizontal siphon centrifuge be avoided, but also the solid and liquid components in the lithium carbonate mother liquor can be effectively separated, thereby avoiding the problem of unqualified water content of the lithium carbonate mother liquor after separation.

[0030] It should be noted that, in the embodiment of the present invention, the set thickness of the solid lithium carbonate is obtained by the staff based on their work experience and can be set according to actual needs.

[0031] It should be noted that, in the embodiment of the present invention, the spacing between the detection claw 10 and the inner wall of the first chamber 26 means that the detection claw 10 and the inner wall of the first chamber 26 are spaced apart in the radial direction, that is, the detection claw 10 and the inner wall of the first chamber 26 are spaced apart in the radial direction. Figure 4 The intervals in the height direction are set.

[0032] It should be noted that, in the embodiment of the present invention, the switch member 11 is a push button switch, the pressing portion of the switch member 11 is a button, and the specific structure of the push button switch can refer to the prior art and will not be described in detail here.

[0033] like Figure 2 and Figure 4 As shown, in an embodiment of the present invention, a pivot hole communicating with the first chamber 26 and a mounting groove 33 communicating with the pivot hole are provided on the housing 39, the switch member 11 is installed in the mounting groove 33, the connecting body 9 is rotatably engaged with the pivot hole, and the pressing claw 28 extends into the mounting groove 33 and abuts against the switch member 11.

[0034] Through the above arrangement, the mounting groove 33 can accommodate the switch component 11 to prevent the switch component 11 from being exposed in the first chamber 26 , thereby preventing solid matter in the first chamber 26 from affecting the operation of the switch component 11 and reducing the probability of failure of the switch component 11 .

[0035] Preferably, in the embodiment of the present invention, the connecting body 9 is sealed with the pivot hole to prevent the solid lithium carbonate in the first chamber 26 from entering the installation groove 33 to avoid affecting the operation of the switch member 11.

[0036] like Figure 1 and Figure 2 As shown, in the embodiment of the present invention, the centrifuge body includes: a driving component, including a motor 2 and a main shaft 3, the motor 2 is arranged on the frame 1, and the main shaft 3 is rotatably arranged relative to the frame 1; a drum 5, located in the casing 39, the drum 5 is rotatably connected to the casing 39, one end of the main shaft 3 is fixedly connected to the output end of the motor 2, and the other end of the main shaft 3 extends into the casing 39 and is fixedly connected to the drum 5, and the drum 5 is provided with a solid outlet 22 connected to the first chamber 26 and a liquid outlet 23 connected to the second chamber 27. The drum 5 can separate the solid and liquid materials.

[0037] In the above technical solution, the main shaft 3 can be rotated under the action of the motor 2, and the rotating main shaft 3 drives the drum 5 in the casing 39 to rotate, thereby driving the lithium carbonate mother liquor in the drum 5 to rotate. Under the action of centrifugal force, solid lithium carbonate is discharged into the first chamber 26 through the solid outlet 22 on the drum 5, and the separated liquid flows into the second chamber 27 through the liquid outlet 23 on the drum 5, so as to achieve the effect of solid-liquid separation of the lithium carbonate mother liquor.

[0038] Specifically, in the embodiment of the present invention, a separation chamber 40 is formed inside the rotating drum 5 .

[0039] It should be noted that, in the embodiment of the present invention, there are two solid outlets 22 and two liquid outlets 23 . The two solid outlets 22 are spaced apart along the circumference of the drum 5 , and the two liquid outlets 23 are spaced apart along the circumference of the drum.

[0040] Preferably, in the embodiment of the present invention, the motor 2 is fixedly connected to the frame 1 .

[0041] like Figure 1 and Figure 3As shown, in an embodiment of the present invention, the centrifuge body further includes: a feed pipe, which is passed through the casing 39; a limit plate 16, which is installed at a first end of the feed pipe, and the second end of the feed pipe is used for feeding materials into; a piston 18, and a plurality of discharge grooves are provided at intervals on the circumference of the piston 18. The piston 18 is slidably arranged relative to the limit plate 16, and the piston 18 has a discharge position protruding from the limit plate 16 to open the discharge groove, and a storage position retracted to the limit plate 16 to close the discharge groove.

[0042] In the above technical solution, lithium carbonate mother liquor enters the feed pipe from the second end of the feed pipe, and the piston 18 is in the storage position. As the lithium carbonate mother liquor in the feed pipe gradually increases, the pressure in the feed pipe gradually increases, thereby forcing the piston 18 in the storage position to slide on the limit plate 16, causing the piston 18 to move away from the second end of the feed pipe, and then causing the piston 18 to be in the discharge position protruding from the limit plate 16 to open the discharge trough, so that the lithium carbonate mother liquor can be discharged from the piston 18 through multiple discharge troughs.

[0043] It should be noted that, in the embodiment of the present invention, the second end of the feed pipe forms a feed port 8 .

[0044] Specifically, in the embodiment of the present invention, when the piston 18 is in the material storage position retracted to the limit plate 16 to close the discharge trough, the outer wall of the piston 18 is sealed with the inner wall of the limit plate 16 to achieve the function of sealing the material storage, thereby preventing the lithium carbonate mother liquor from leaking through the discharge trough; wherein, the material of the piston 18 is a flexible material, and the specific structure of the piston 18 can adopt the existing technology to achieve the sealing cooperation between the piston 18 and the inner wall of the limit plate 16, which will not be repeated here.

[0045] Preferably, in an embodiment of the present invention, the limiting plate 16 is fixedly connected to the first end of the feed pipe.

[0046] like Figure 4 As shown, in the embodiment of the present invention, the piston 18 is a cylindrical structure with one end open and the other end closed, and a discharge groove is provided on the circumferential side wall of the cylindrical structure, and the discharge groove is connected to the interior of the cylindrical structure, and a plurality of ribs 30 are provided at the open end of the cylindrical structure, and the plurality of ribs 30 are arranged at intervals along the circumference of the cylindrical structure, and each rib 30 extends in the radial direction of the cylindrical structure away from the axis of the cylindrical structure; a plurality of slide grooves 29 are provided on the inner wall of the limit plate 16, and the plurality of slide grooves 29 slide in correspondence with the plurality of ribs 30, and a limit plate 34 is provided in each slide groove 29, and the limit plate 34 is located at one end of the limit plate 16 away from the second end of the feed pipe; the centrifuge body also includes a plurality of elastic members 17 arranged corresponding to the plurality of ribs 30, one end of the elastic member 17 abuts against the corresponding rib 30, and the other end of the elastic member 17 abuts against the corresponding limit plate 34.

[0047] In the above technical solution, on the one hand, the chute 29 can guide the rib 30. When the pressure in the feed pipe increases, the rib 30 can move on the chute 29 in a direction away from the second end of the feed pipe, thereby preventing the movement direction of the piston 18 from deviating. On the other hand, since the limit plate 34 is located at the end of the limit plate 16 away from the second end of the feed pipe, that is, at Figure 2 The middle limit plate 34 is located at the left end of the slide groove 29. In this way, when the rib 30 moves from the right end of the slide groove 29 to the left end of the slide groove 29, the limit plate 34 can resist the rib to prevent the rib 30 from falling out of the slide groove 29, thereby preventing the piston 18 from falling out of the limit plate 16; on the other hand, when the rib 30 moves in the direction close to the limit plate 34, the elastic member 17 is compressed, and the piston 18 is in the discharge position protruding from the limit plate 16 to open the discharge chute. When the feed valve is closed and the feed pipe no longer feeds, the pressure in the feed pipe gradually decreases, the elastic member 17 recovers its deformation and drives the piston 18 to move in the direction close to the second end of the feed pipe, so that the piston 18 returns to the storage position where it is retracted to the limit plate 16 to close the discharge chute.

[0048] Preferably, in the embodiment of the present invention, the elastic member 17 is a spring, wherein one end of the spring is fixedly connected to the corresponding rib 30 , and the other end of the spring is fixedly connected to the corresponding limit plate 34 .

The discharge pipe 7 extends into the drum 5 and is connected with the discharge box 19. When the piston 18 is in the discharge position, the piston 18 extends into the discharge box 19, and the feed pipe is connected with the interior of the discharge box 19 through the discharge groove.

[0050] Through the above arrangement, the lithium carbonate mother liquor in the feed pipe flows into the discharge box 19 through the discharge groove on the piston 18, and the main shaft 3 drives the discharge box 19 to rotate through the discharge pipe 7. Under the action of centrifugal force, the lithium carbonate mother liquor in the discharge box 19 is discharged into the drum 5 through the leakage groove 20, so that the lithium carbonate mother liquor can be discharged into the drum 5 more evenly, thereby being able to more effectively separate the lithium carbonate mother liquor in the drum 5.

[0051] It should be noted that, in the embodiment of the present invention, the discharge box 19 is a cylindrical structure, and four leakage grooves 20 are provided on the circumferential side wall of the discharge box 19 . The four leakage grooves 20 are evenly spaced along the circumference of the discharge box 19 .

[0052] Preferably, in an embodiment of the present invention, the feed pipe and the discharge box 19 are fixedly connected.

[0055] In the above technical solution, the rotating main shaft 3 drives the first pulley 36 to rotate, and the first pulley 36 rotates the second pulley 31 through the first belt 12 to rotate the linkage component 13, thereby rotating the third pulley 32, and the third pulley 32 drives the fourth pulley 37 to rotate through the second belt 14, thereby driving the discharge pipe 7 to rotate, so as to throw the lithium carbonate mother liquor in the discharge box 19 into the drum 5. In this way, the drum 5 and the discharge box 19 can be driven to rotate at the same time by a motor 2, thereby avoiding the need to set up an additional driving device to drive the discharge box 19 to rotate, thereby reducing production costs.

[0056] In one embodiment, the first transmission component, the linkage component 13 and the second transmission component may not be provided, and an additional motor may be provided to drive the discharge pipe 7 to rotate.

[0058] In the above technical solution, by setting the annular partition 38, the interior of the shell of the passive disk 6 can be separated from the interior of the centrifugal chamber 4 to form an isolated first chamber 26 and a second chamber 27, thereby avoiding the mixing of solid lithium carbonate and liquid produced after separation.

The separated liquid flows from the liquid outlet 23 into the second chamber 27 under the action of the siphon device, and enters the siphon device from the second chamber 27 through the discharge pipe 25.

[0063] Preferably, in the embodiment of the present invention, the drain pipe 25 is fixedly connected to the passive disk 6 of the housing 39 .

[0064] It should be noted that in the embodiment of the present invention, the siphon device can be a horizontal solid / liquid siphon mixing pump, which mainly includes a stator and a rotor, and generates a vacuum through high-speed rotation to achieve liquid flow. Its specific structure can adopt existing technology and will not be repeated here.

[0065] It should be noted that in the embodiment of the present invention, a filter screen is laid on the inner wall of the drum 5 and the spiral conveying sheet 21. In this way, under the action of centrifugal force, the material is separated into solid and liquid in the drum 5 to form solid lithium carbonate and liquid, and under the action of siphon, the liquid can pass through the filter screen and enter the second chamber 27 from the liquid outlet 23, while the solid lithium carbonate is retained in the drum 5 by the filter screen and transported to the solid outlet 22 through the spiral conveying sheet 21.

[0066] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: when the feed valve is opened, the material to be separated is forced into the separation chamber through the feed port by pressure, so that the material is separated into solid and liquid in the separation chamber under the action of centrifugal force, wherein the liquid enters the second chamber through the liquid outlet, and the solid enters the first chamber through the solid outlet and adheres to the inner wall surface of the first chamber. When the solid in the first chamber accumulates too much, the detection component can sense it in time and drive the switch component to close the feed valve in time, so as to avoid the problem of continuous feeding into the separation chamber, thereby avoiding the problem of excessive accumulation of material in the separation chamber due to the difficulty of the material in the separation chamber being discharged into the first chamber in time. In this way, on the one hand, the probability of blockage inside the horizontal siphon centrifuge can be reduced, thereby reducing the probability of failure of the horizontal centrifuge; on the other hand, the solid-liquid separation of the material in the separation chamber can be effectively performed, thereby avoiding the phenomenon of unqualified moisture content of the material, thereby avoiding unnecessary economic losses.

[0067] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
