Technical Field

[0001] The present invention relates to the technical field of mechanical separation, and particularly to a vertical centrifuge. Background Art

[0002] A vertical centrifuge is an efficient solid-liquid separation device. The vertical centrifuge has technical characteristics and advantages such as small floor area, convenient installation and maintenance, simple operation, low energy consumption, fast filtration speed, efficient locking mechanism, high oil mist sedimentation efficiency, small vibration, low noise, and long continuous operation time. These characteristics enable the vertical centrifuge to have a wide application prospect in multiple industrial fields.

[0003] The Chinese invention patent with the publication number CN119158709A discloses a vertical centrifuge for solid-liquid separation, including a vertical centrifuge body.

Detailed implementation manners

[0029] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments.

[0030] Generally, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention.

[0031] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0032] Refer to the attached description Figure 1-8The present embodiment provides a vertical centrifuge, including a base 1, a fixed base 11 is fixedly installed at one end of the base 1, a motor 12 is fixedly installed on the fixed base 11, a casing 2 is fixedly installed at the other end of the base 1, a cover 22 is installed on the top of the casing 2 by bolts, the cover 22 is composed of two semicircular plates 23, a rotating shaft 3 is rotatably connected in the casing 2, the bottom of the rotating shaft 3 is transmission-connected to the output end of the motor 12 by a transmission belt 4, a drum bottom 24 is slidably installed on the top of the rotating shaft 3, a compression spring 25 is connected between the drum bottom 24 and the rotating shaft 3, and a side of the drum bottom 24 close to the compression spring 25 is provided There is a positioning assembly 5, an outer drum 26 and an inner drum 27 are fixedly mounted on the drum bottom 24, a basket cover 28 is mounted on the top of the outer drum 26 and the inner drum 27 by bolts, the positioning assembly 5 comprises a fixing ring 51 fixedly mounted on the drum bottom 24 near the side of the compression spring 25, a screw 52 is threadedly connected to one side of the fixing ring 51, a rotating sleeve 53 is rotatably sleeved on one end of the screw 52, ​​a wedge block 54 is fixedly mounted on one end of the rotating sleeve 53, the wedge block 54 passes through one side of the drum bottom 24 and is slidably matched with the drum bottom 24, and an oblique opening matching the shape of the wedge block 54 is opened on one side of the rotating shaft 3.

[0033] During operation, the basket cover 28 is taken out, and the separated materials are placed in the interlayer between the outer drum 26 and the inner drum 27. After filling, the basket cover 28 is covered. During this process, the screw 52 in the positioning assembly 5 does not drive the rotating sleeve 53 and the wedge block 54 thereon to contact the rotating shaft 3, that is, the fixed ring 51 and the drum bottom 24 are unlocked from the rotating shaft 3 at this time. When the separated materials are gradually added into the interlayer between the outer drum 26 and the inner drum 27, the drum bottom 24 can be continuously shaken by the compression spring 25 to continuously shake the separated materials, so that the separated materials can be evenly laid in the interlayer between the outer drum 26 and the inner drum 27 during the feeding process, so that the separated materials can be laid flat in the interlayer between the outer drum 26 and the inner drum 27 without additional steps during the feeding process, thereby improving the feeding efficiency and ensuring the subsequent centrifugal separation effect.

[0034] After the feeding is completed, rotate the screw 52, and push the wedge block 54 into the inside of the rotating shaft 3 through the rotating sleeve 53. Since one side of the rotating shaft 3 is provided with an inclined opening that matches the shape of the wedge block 54, no matter what the weight of the feeding is and what the final sinking height of the bottom of the rotating drum 24 is, as long as the deformation of the compression spring 25 remains within the preset elastic range, the wedge block 54 can continuously extend into the rotating shaft 3 during the inward pushing process through wedge-shaped cooperation, ensuring that the bottom of the rotating drum 24 can lock the rotating shaft 3, facilitating the subsequent centrifugal separation work. Fix the basket cover 28 on the outer rotating drum 26 and the inner rotating drum 27 through bolts, and seal the upper end of the casing 2 by bolting the two semi-circular plates 23. Start the motor 12 on the fixed seat 11, and then drive the rotating shaft 3, the bottom of the rotating drum 24, the inner rotating drum 27, and the outer rotating drum 26 to rotate through the transmission belt 4. The liquid phase is discharged from the filter holes on the outer rotating drum 26, and a water retaining ring can be provided at the upper end of the outer rotating drum 26 to prevent the separated liquid from splashing.

[0035] Specifically, sliding grooves 29 are provided on the inner walls of both sides of the casing 2. Scraping components 6 and adjusting components 7 are provided on both sides inside the casing 2. The scraping component 6 includes a slider 61 that is slidably engaged with the sliding groove 29. One end of the slider 61 away from the rotating shaft 3 is fixedly installed with a rotating seat 62. A rotating rod 63 is rotatably connected inside the rotating seat 62. One end of the rotating rod 63 close to the rotating shaft 3 is fixedly installed with an arc-shaped scraper 64. The circular scraper formed by the two arc-shaped scrapers 64 in the horizontal state can fit the inner wall of the casing 2. A first opening 65 for accommodating the arc-shaped scraper 64 is provided in the slider 61. A dial rod 66 is fixedly installed at the end of the rotating rod 63 away from the rotating shaft 3. A number of second openings 67 are circumferentially arranged on the rotating rod 63. A sliding rod 68 is slidably connected in each second opening 67. A spherical head is fixedly installed at one end of each sliding rod 68 away from the rotating rod 63. A first spring 69 is connected between each sliding rod 68 and the corresponding second opening 67. A third opening 610 for accommodating the spherical head is provided at the position of the rotating seat 62 corresponding to the second opening 67.

[0036] Specifically, the adjusting component 7 includes two fixing blocks 71 symmetrically arranged about the middle of the casing 2. The two fixing blocks 71 are respectively arranged at the upper and lower parts of the casing 2. Each fixing block 71 is fixedly installed on the sliding groove 29. An adjusting rod 72 is rotatably connected inside each fixing block 71. A dial block that cooperates with the dial rod 66 is fixedly installed at one end of each adjusting rod 72. A second spring 73 is provided at the rotational connection of each adjusting rod 72 and the corresponding fixing block 71.

[0037] Specifically, a baffle 8 is fixedly installed in each sliding groove 29.

[0038] Specifically, L-shaped rods 9 are fixedly installed on both sides of the casing 2. An electric telescopic rod 10 is fixedly installed at the top of each L-shaped rod 9. The output end of each electric telescopic rod 10 is arranged downward and fixedly connected to the corresponding slider 61.

[0039] Specifically, two semi-circular holes are formed in each semi-circular plate 23, and the two semi-circular holes on the two semi-circular plates 23 can form two circular holes. Each circular hole is slidably connected to the output end of the corresponding electric telescopic rod 10. The semi-circular holes on the two semi-circular plates 23 and the output end of the electric telescopic rod 10 are in sealed sliding connection to ensure that the liquid phase will not splash during the separation work.

[0040] Specifically, cross blocks 210 are fixedly installed on both sides of the bottom of the drum 24. Each cross block 210 is located below the corresponding slider 61.

[0041] During unloading, the bolts are manually removed, the machine cover 22 and the basket cover 28 are taken out in sequence, and then the material can be taken out. Since the inner wall of the casing 2 will have residual liquid phase after the centrifugal separation work, it needs to be scraped out by the scraping assembly 6. By rotating the screw rod 52, the fixed ring 51 and the bottom of the drum 24 are unlocked from the rotating shaft 3. At this time, the electric telescopic rod 10 on the L-shaped rod 9 can be started. The electric telescopic rod 10 drives the slider 61 to slide along the chute 29 on the inner wall of the casing 2. During the first downward movement of the slider 61, the dial rod 66 on the rotating rod 63 contacts the dial block in the adjusting assembly 7 above the casing 2. The dial block can rotate downward, and then is reset by the second spring 73 on the adjusting rod 72, without causing the rotating rod 63 to rotate. The slider 61 descends, and the two arc-shaped scrapers 64 can scrape the residual liquid phase on the inner wall of the casing 2 downward. When the dial rod 66 contacts the dial block below the casing 2, the lower part of the dial block is limited by the fixed block 71 and cannot rotate downward. At this time, the dial rod 66 will drive the rotating rod 63 to rotate a certain angle, so that the arc-shaped scraper 64 is in an inclined state, and the outer wall of the circular scraper no longer fits the inner wall of the casing 2, allowing the liquid phase to pass through;

[0042] During the upward movement of the slider 61, the dial rod 66 on the rotating rod 63 contacts the dial block below the casing 2. The dial block can rotate upward, without causing the rotating rod 63 to rotate. The slider 61 ascends, and the arc-shaped scraper 64 is always in an inclined state, so the liquid phase will not be scraped back to the upper part of the inner wall of the casing 2 again. When the dial rod 66 contacts the dial block above the casing 2 again, the upper part of the dial block is limited by the fixed block 71 and cannot rotate upward. At this time, the dial rod 66 will drive the rotating rod 63 to recover the previously rotated angle, so that the arc-shaped scraper 64 is in a horizontal state, and the outer wall of the circular scraper fits the inner wall of the casing 2 again, not allowing the liquid phase to pass through, so as to continue to scrape the liquid phase downward along the casing 2.

[0043] During the rotation of the rotating rod 63, since the sliding rod 68 is arranged in the second opening 67 inside the rotating rod 63, the spherical head on the sliding rod 68 contacts the inner wall of the rotating seat 62 during rotation, compressing the first spring 69, and returning to the extended state after the rotating rod 63 rotates a certain angle, causing the sliding rod 68 to snap into another third opening 610, thereby quickly completing the locking of the rotation angle of the arc-shaped scraper 64 in the first opening 65.

[0044] In the above process, the arc-shaped scraper 64 reciprocates up and down through the electric telescopic rod 10 to scrape the liquid phase in a cycle, ensuring that the liquid phase on the inner wall of the casing 2 can be completely collected. Moreover, a baffle 8 is arranged in the chute 29, so that the liquid phase will not further penetrate into the chute 29. Even if there is a little penetration, since the arc-shaped scraper 64 is close to the inner wall of the casing 2 when descending during the scraping process, the liquid phase in the chute 29 can be pushed downward by the air flow and flow out.

[0045] During the reciprocating sliding of the slider 61, it will continuously contact the upper part of the cross block 210, slightly compressing the compression spring 25, which can cause the bottom of the rotating drum 24 to vibrate. On the one hand, it can shake the separated material between the outer rotating drum 26 and the inner rotating drum 27 evenly, facilitating the collection of the material. On the other hand, it can continue to shake out the residual liquid phase between the materials, further improving the solid-liquid separation effect.

[0046] Specifically, an inclined opening is provided below the chute 29 to facilitate the outflow of the liquid phase.

[0047] Specifically, a mother liquor port 21 is provided on one side of the casing 2 for discharging the liquid phase.

[0048] Specifically, an opening for accommodating the transmission belt 4 is provided below the casing 2.

[0049] When the centrifuge of the present invention is working, the basket cover 28 is taken out, and the material to be separated is placed in the interlayer between the outer rotating drum 26 and the inner rotating drum 27. After filling, the basket cover 28 is covered. During this process, the screw rod 52 in the positioning assembly 5 does not drive the rotating sleeve 53 and the wedge block 54 thereon to contact the rotating shaft 3, that is, at this time, the fixed ring 51 and the bottom of the rotating drum 24 are in an unlocked state with the rotating shaft 3. When the material to be separated is gradually added to the interlayer between the outer rotating drum 26 and the inner rotating drum 27, the bottom of the rotating drum 24 can continuously vibrate through the compression spring 25, continuously jolting the material to be separated, so that the material to be separated can be evenly laid in the interlayer between the outer rotating drum 26 and the inner rotating drum 27 during the feeding process, enabling the material to be separated to be laid flat in the interlayer between the outer rotating drum 26 and the inner rotating drum 27 without additional processes during the feeding process, improving the feeding efficiency while ensuring the subsequent centrifugal separation effect.

[0050] After the feeding is completed, rotate the screw rod 52, and push the wedge block 54 into the inside of the rotating shaft 3 through the rotating sleeve 53. Since an inclined opening matching the shape of the wedge block 54 is provided on one side of the rotating shaft 3, no matter what the weight of the feeding is and what the final sinking height of the drum bottom 24 is, as long as the deformation of the compression spring 25 remains within the preset elastic range, the wedge block 54 can continuously extend into the rotating shaft 3 during the inward pushing process through wedge-shaped cooperation, ensuring that the drum bottom 24 can lock the rotating shaft 3, facilitating the subsequent centrifugal separation work;

[0051] Fix the basket cover 28 on the outer drum 26 and the inner drum 27 through bolts, and seal the upper end of the casing 2 by bolts with two semi-circular plates 23. Start the motor 12 on the fixed seat 11, and then drive the rotating shaft 3, the drum bottom 24, the inner drum 27 and the outer drum 26 to rotate through the transmission belt 4. The liquid phase is discharged from the filter holes on the outer drum 26 and discharged out of the casing 2 through the mother liquid port 21. A water retaining ring can also be provided at the upper end of the outer drum 26 to prevent the separated liquid from splashing.

[0052] When discharging after dehydration, manually remove the bolts, take out the machine cover 22 and the basket cover 28 in sequence, and then take out the material. Since the inner wall of the casing 2 will have residual liquid phase after the centrifugal separation work, it needs to be scraped out by the scraping assembly 6. By rotating the screw rod 52, the fixed ring 51 and the drum bottom 24 are in an unlocked state with the rotating shaft 3. At this time, the electric telescopic rod 10 on the L-shaped rod 9 can be started, and the electric telescopic rod 10 drives the slider 61 to slide along the chute 29 on the inner wall of the casing 2. During the first downward sliding of the slider 61, the dial rod 66 on the rotating rod 63 contacts the dial block in the adjusting assembly 7 located above the casing 2. The dial block can rotate downward, and then reset through the second spring 73 on the adjusting rod 72, without rotating the rotating rod 63. The slider 61 descends, and the two arc-shaped scrapers 64 can scrape the residual liquid phase on the inner wall of the casing 2 downward. When the dial rod 66 contacts the dial block located below the casing 2, the lower part of the dial block is limited by the fixed block 71 and cannot rotate downward. At this time, the dial rod 66 will drive the rotating rod 63 to rotate a certain angle, making the arc-shaped scraper 64 in an inclined state, and the outer wall of the circular scraper no longer fits the inner wall of the casing 2, allowing the liquid phase to pass through;

[0053] During the upward movement of the slider 61, the dial rod 66 on the rotating rod 63 contacts the dial block located below the casing 2. The dial block can rotate upward, without rotating the rotating rod 63, and the slider 61 rises normally. The arc-shaped scraper 64 has been in an inclined state, so it will not scrape the liquid phase back to the upper part of the inner wall of the casing 2 again. When the dial rod 66 contacts the dial block located above the casing 2 again, the upper part of the dial block is limited by the fixed block 71 and cannot rotate upward. At this time, the dial rod 66 will drive the rotating rod 63 to restore the previously rotated angle, making the arc-shaped scraper 64 in a horizontal state, and the outer wall of the circular scraper fits the inner wall of the casing 2 again, not allowing the liquid phase to pass through, and being able to scrape the liquid phase continuously downward to the lower part of the casing 2.

[0054] During the rotation of the rotating rod 63, since the sliding rod 68 is arranged in the second opening 67 in the rotating rod 63, the spherical head on the sliding rod 68 contacts the inner wall of the rotating seat 62 during rotation, compressing the first spring 69, and returning to the extended state after the rotating rod 63 rotates a certain angle, so that the sliding rod 68 is caught in another third opening 610, quickly completing the locking of the rotation angle of the arc-shaped scraper 64 in the first opening 65.

[0055] The above process is the cycle of the arc-shaped scraper 64 reciprocating up and down through the electric telescopic rod 10 to scrape the liquid phase, ensuring that the liquid phase on the inner wall of the machine shell 2 can be completely collected. Moreover, a baffle 8 is arranged in the chute 29, so that the liquid phase will not further penetrate into the chute 29. Even if there is a little penetration, since the arc-shaped scraper 64 is close to the inner wall of the machine shell 2 when descending during the scraping process, the liquid phase in the chute 29 can be pushed downward to flow out by the air flow.

[0056] During the reciprocating sliding of the slider 61, it will continuously contact the upper part of the cross block 210, slightly compressing the compression spring 25, which can cause the bottom of the rotating drum 24 to vibrate. On the one hand, it can shake the separated materials between the outer rotating drum 26 and the inner rotating drum 27 evenly, facilitating the collection of materials. On the other hand, it can continue to shake out the residual liquid phase between the materials, further improving the solid-liquid separation effect.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
