Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example 1:

[0039] Reference Figures 1-9, which is a first embodiment of the present invention, provides a horizontal centrifugal separation device for ferrous sulfate, including a frame 1 and a supporting platform 2, the supporting platform 2 is arranged on the frame 1, a drum motor 3 and a spiral drive motor 4 are installed on the supporting platform 2, a solid phase outlet and a liquid phase outlet are respectively provided on both sides of the supporting platform 2, the drum motor 3 is also connected to a drum assembly 5, both ends of the drum assembly 5 pass through the bearing seats on both sides of the supporting platform 2, a cover 21 hinged on the supporting platform 2 is used to cover the drum assembly 5, a spiral assembly 6 is provided in the drum assembly 5, and both ends of the spiral assembly 6 pass through the drum assembly 5 and are respectively connected to a material inlet pipe 7 and the spiral drive motor 4;

[0040] The drum assembly 5 includes a rear cover shaft 53 , an outer circumferential surface of which is provided with an annular groove and a plurality of equally spaced drainage holes 531 . The drainage holes 531 are connected to the liquid phase outlet, and the movable filter assembly 10 covers the drainage holes 531 .

[0041] The frame 1 and the supporting platform 2 are made of steel structures. The supporting platform 2 is provided with a concave structure so that the drum assembly 5 can be placed in the supporting platform 2. At the same time, the solid phase outlet and the liquid phase outlet are located on both sides of the concave structure. The material inlet pipe 7 flows into the solid-liquid mixture containing ferrous sulfate, and the solid-liquid mixture flows into the drum assembly 5 after being rotated by the spiral assembly 6. The ferrous sulfate is discharged under the push of the spiral assembly 6, thereby achieving the purpose of centrifugal separation.

[0042] The drum assembly 5 includes a conical drum 51, a straight drum 52, a rear cover shaft 53 and a front cover shaft 54. The flanges between the conical drum 51 and the straight drum 52 are assembled into a drum by bolts. The other end ports of the conical drum 51 and the straight drum 52 are covered by the front cover shaft 54 and the rear cover shaft 53 through flanges respectively. The rear cover shaft 53 and the front cover shaft 54 are supported by bearing seats on both sides of the supporting platform 2, and the hollow interiors of the front cover shaft 54 and the rear cover shaft 53 are connected to the inner cavity of the drum. The shaft of the front cover shaft 54 is connected to the shaft of the drum motor 3 through a belt.

[0043] The conical drum 51 and the straight drum 52 are easily installed and disassembled through flange assembly. The front cover shaft 54 and the rear cover shaft 53 cover the ends of the conical drum 51 and the straight drum 52 respectively. The center of the front cover shaft 54 and the rear cover shaft 53 are equipped with a bushing. The drum motor 3 drives the front cover shaft 54 to rotate via a belt, thereby driving the conical drum 51 and the straight drum 52 to rotate. The rear cover shaft 53 and the front cover shaft 54 are supported by bearing seats on both sides to reduce rotational friction and allow the conical drum 51 and the straight drum 52 to rotate. A plurality of fixed holes 541 are provided on the outer circumference of the front cover shaft 54, which are connected to the solid phase outlet.

[0044] The spiral assembly 6 includes a spiral barrel 61, a differential 62, a spiral blade 63 and a barrel shaft 64. The spiral barrel 61 is placed in the drum, the spiral blade 63 is fixed on the spiral barrel 61 and the outer wall of the spiral blade 63 is in contact with the inner wall of the drum, one end of the spiral barrel 61 is connected to the barrel shaft 64, and the other end of the barrel shaft 64 passes through the front cover shaft 54 and is connected to the spiral drive motor 4 through the differential 62; the other end of the spiral barrel 61 passes through the rear cover shaft 53 and penetrates into the protective cylinder to be connected to the material inlet pipe 7; a number of material holes are opened on the spiral barrel 61, and the material holes are connected to the inner cavity of the drum and the inner cavity of the spiral barrel 61 and the material inlet pipe 7.

[0045] The solid-liquid mixture first flows into the spiral barrel 61 through the material inlet pipe 7. The spiral barrel 61 rotates under the drive of the spiral drive motor 4, and the spiral barrel 61 drives the spiral blade 63 to rotate synchronously during the rotation. During the rotation of the spiral barrel 61, the centrifugal force generated by the solid-liquid mixture during the rotation of the spiral barrel 61 drives the solid-liquid mixture to flow into the drum from the material hole. Ferrous sulfate is soluble in water, and ferrous sulfate dissolves in water. The water containing ferrous sulfate in the solid-liquid mixture is discharged from the liquid phase outlet, and the solid impurities are pushed by the spiral blade 63 to be discharged from the solid phase outlet, thereby realizing the separation of solid and liquid.

[0046] The control assembly 8 includes a support frame 81, a centrifugal ball 82, a first connecting rod 83, a second connecting rod 84, an inner arc 85, an outer ring 86, and a reinforcing rod 87. One end of the support frame 81 is fixed to the spiral barrel 61, and the other end of the support frame 81 is hinged to the middle part of the first connecting rod 83. The centrifugal ball 82 is fixed to one end of the first connecting rod 83, and the other end of the first connecting rod 83 is fixed to the sliding ring 9 through the hinged second connecting rod 84. The sliding ring 9 is sleeved on the spiral barrel 61, and the side of the sliding ring 9 is movably connected to the fixed ring. The fixed ring slides along the length direction of the protective cylinder and is fixed to the side of the outer ring 86 through the arc-shaped side rod.

[0047] The inner circumference of the outer ring 86 is fixed to the inner arc 85 through a number of reinforcing rods 87. The inner arc 85 is sleeved on the material inlet pipe 7. A T-ring is fixed to the side of the sliding ring 9. The side circumference of the fixed ring is provided with a ring groove for the T-ring to be inserted. The sliding ring 9 rotates around the fixed ring and slides along the spiral barrel 61. The T-ring structure is set so that the sliding ring 9 can rotate around the fixed ring, while the fixed ring can only slide along the length direction and cannot rotate.

[0048] The fixed ring and the inner arc 85 are also connected by gravity. The inner wall of the spiral barrel 61 is covered with a wear-resistant bushing, and the edge of the material hole is covered with the wear-resistant bushing. The wear-resistant bushing adopts a highly wear-resistant structure to make the inner wall of the spiral barrel 61 highly wear-resistant, thereby avoiding the problem of damage to the inner wall of the spiral barrel 61 and the edge of the material hole caused by collision of solid impurities.

[0049] Among them, the T-ring structure allows the sliding ring 9 to rotate around the fixed ring, while the fixed ring cannot rotate and can only move. The sliding ring 9 can pull the inner arc 85 during the rotation process;

[0050] The support frame 81 rotates synchronously with the spiral barrel 61. During the rotation of the support frame 81, due to the centrifugal force, the centrifugal ball 82 rotates outward, which will pull the first connecting rod 83 to tilt. During the tilting process of the first connecting rod 83, the second connecting rod 84 will be pulled to move. The second connecting rod 84 pulls the sliding ring 9 to move at the same time, and the outer ring 86 is also pulled to move through the fixed ring and the arc side rod, and the inner arc 85 is also driven to move synchronously.

[0051] The filter assembly 10 includes an inner filter ring frame 1001, a filter mesh 1002, a filter back plate 1003, a reinforcing connecting rod 1004, and an outer filter ring frame 1005. The inner and outer filter ring frames 1001 and 1005 are secured together by a plurality of filter back plates 1003. The filter mesh 1002 is inserted into the annular channel formed by the inner and outer filter ring frames 1001 and 1005, and is magnetically attracted to the filter back plates 1003. The filter back plates 1003 are secured to the sides of the outer ring 86 via reinforcing connecting rods 1004. The ring frame formed by the inner and outer filter ring frames 1001 and 1005 is inserted into the annular groove of the rear cover shaft 53. The filter mesh 1002 is used to filter impurities in the liquid.

[0052] The filter ring net 1002 adopts a magnetic attraction method, which is easier to install and disassemble. The filter ring net 1002 is made of metal, which is more resistant to high temperature, corrosion and wear. The use of metal material can greatly extend the service life of the metal filter net and avoid frequent replacement. After the rotation speed of the spiral barrel 61 increases, the centrifugal ball 82 slowly deviates outward, thereby moving by pulling the outer ring 86. During the movement of the outer ring 86, the filter inner ring frame 1001 and the filter outer ring frame 1005 can be driven to insert into the ring groove of the rear cover shaft 53. After the liquid flows through the filter ring net 1002 through the drainage hole 531, some solid impurities are filtered out by the filter ring net 1002. After the speed of the spiral barrel 61 decreases until it stops, the centrifugal ball 82 slowly returns to its original position, the outer ring 86 moves in the opposite direction, the filter assembly 10 is detached from the ring groove of the rear cover shaft 53, and the filter ring net 1002 is detached from the drainage hole 531, so that the impurities on the filter ring net 1002 can be cleaned to avoid clogging problems caused by long-term use.

[0053] Example 2:

[0054] Reference Figure 10-11, which is the second embodiment of the present invention, is different from the first embodiment, in that the mother liquor to be treated is a mixture of titanium liquid and ferrous sulfate crystals, and the mother liquor enters the mother liquor outlet chamber of the drum through a feed pipe. In the prior art, controlling the flow rate of the mother liquor requires additional pumps or solenoid valves and other structures, and the power equipment increased in order to adjust the mother liquor flow rate causes power waste.

[0055] The control component 8 also includes a gear 88 and a valve 89. One end of the rotating shaft that radially passes through the material inflow pipe 7 is fixed to the gear 88, and the other end is fixed to the valve 89 inside the material inflow pipe 7. The gear 88 is engaged with the rack on the port of the inner arc 85; the movement of the rack drives the gear 88 to rotate 0°-180°, and the valve 89 is used to open or close the material inflow pipe 7.

[0056] As the inner arc 85 moves, the rack drives the gear 88 to rotate, and the gear 88 rotates to transmit power to the valve 89 through the rotating shaft, thereby controlling the rotation of the valve 89 so as to control the opening and closing size of the valve 89 through the centrifugal force generated by the rotation. There is no need to install additional valve 89 control equipment, and the size of the valve 89 can be controlled only by the rotation speed.

[0057] After the spiral drive motor 4 drives the spiral barrel 61 to reduce its speed, the centrifugal force of the centrifugal ball 82 is reduced, and the centrifugal ball 82 slowly returns to its original position under the drive of gravity. Similarly, the gear 88 moves in the opposite direction to drive the valve 89 to reverse to its initial position, and the material inflow pipe 7 is sealed by the valve 89 to stop feeding.

[0058] The control component 8 is set to control the flow rate of the material into the pipe 7 according to the rotation speed of the spiral component 6. The faster the spiral component 6 rotates, the valve 89 of the material inflow pipe 7 opens to the maximum, so that a large amount of solid-liquid mixture can flow in. The slower the spiral component 6 rotates, the valve 89 of the material inflow pipe 7 opens to the minimum. The flow rate is controlled by the rotation speed, and there is no need to add additional equipment to control the opening width of the valve 89, which can effectively reduce the control cost.

[0059] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
