Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0022] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0023] Reference Manual Attached 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.

[0024] 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.

[0025] After the feeding is completed, the screw 52 is rotated, and the wedge block 54 is pushed into the inside of the rotating shaft 3 through the rotating sleeve 53. Since an oblique opening matching the shape of the wedge block 54 is opened on one side of the rotating shaft 3, no matter how the weight of the added material is and how the final sinking height of the drum bottom 24 is, as long as the deformation of the compression spring 25 is kept within the pre-set elastic range, the wedge block 54 can continuously extend into the rotating shaft 3 through the wedge-shaped cooperation during the inward pushing process, ensuring that the drum bottom 24 can lock the rotating shaft 3, which is convenient for subsequent centrifugal separation work. The basket cover 28 is fixed to the outer drum 26 and the inner drum 27 by bolts, and the two semicircular plates 23 are sealed to the upper end of the casing 2 by bolts, and the motor 12 on the fixing seat 11 is started, and then the rotating shaft 3, the drum bottom 24, the inner drum 27 and the outer drum 26 are driven to rotate by the transmission belt 4, and the liquid phase is discharged from the filtering holes on the outer drum 26. A water retaining ring can also be provided on the upper end of the outer drum 26 to prevent the separated liquid from splashing.

[0026] Specifically, the inner walls of both sides of the casing 2 are provided with slide grooves 29, and the scraping components 6 and the adjusting components 7 are provided on both sides of the casing 2. The scraping components 6 include a slider 61 that slides with the slide groove 29. The end of the slider 61 away from the rotating shaft 3 is fixedly installed with a rotating seat 62, and a rotating rod 63 is rotatably connected in the rotating seat 62. The end of the rotating rod 63 close to the rotating shaft 3 is fixedly installed with an arc scraper 64. The circular scraper formed by the two arc scrapers 64 in the horizontal state can fit the inner wall of the casing 2. The slider 61 is provided with a space for accommodating A first opening 65 of the arc scraper 64, a lever 66 is fixedly installed on the end of the rotating rod 63 away from the rotating shaft 3, a plurality of second openings 67 are opened in a circular array on the rotating rod 63, a sliding rod 68 is slidably connected in each second opening 67, a spherical head is fixedly installed on the 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, and a third opening 610 for accommodating the ball head is opened at a position corresponding to the second opening 67 on the rotating seat 62.

[0027] Specifically, the adjustment assembly 7 includes two fixed blocks 71 symmetrically arranged about the middle part of the casing 2, and the two fixed blocks 71 are respectively arranged at the upper and lower parts of the casing 2, each fixed block 71 is fixedly installed on the slide groove 29, and an adjustment rod 72 is rotatably connected in each fixed block 71, and a shift block that cooperates with the shift rod 66 for movement is fixedly installed at one end of each adjustment rod 72, and a second spring 73 is provided at the rotation connection between each adjustment rod 72 and the corresponding fixed block 71.

[0028] Specifically, a baffle 8 is fixedly installed in each slide groove 29 .

[0029] Specifically, L-shaped rods 9 are fixedly installed on both sides of the housing 2, and an electric telescopic rod 10 is fixedly installed on 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.

[0030] Specifically, two semicircular holes are provided on each semicircular plate 23, and the two semicircular holes on the two semicircular plates 23 can form two circular holes, and each circular hole is slidably connected to the output end of the corresponding electric telescopic rod 10. The semicircular holes on the two semicircular plates 23 are sealed and slidably connected to the output end of the electric telescopic rod 10 to ensure that the liquid phase does not splash during the separation work.

[0031] Specifically, cross blocks 210 are fixedly mounted on both sides of the drum bottom 24 , and each cross block 210 is located below a corresponding sliding block 61 .

[0032] When unloading, manually remove the bolts, take out the machine cover 22 and basket cover 28 in turn, and then take out the materials. Since the inner wall of the casing 2 will have residual liquid after centrifugal separation, it needs to be scraped out by the scraper assembly 6. By rotating the screw 52, ​​the fixing 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 slide groove 29 on the inner wall of the casing 2. During the first downward movement of the slider 61, the lever 66 on the rotating rod 63 contacts the lever block in the adjustment assembly 7 located above the casing 2, and the lever block can be rotated downward. , and then the second spring 73 on the adjusting rod 72 is reset, the rotating rod 63 will not rotate, the slider 61 drops, and the two arc scrapers 64 can scrape the liquid phase remaining on the inner wall of the casing 2 downward. When the lever 66 contacts the shift block located below the casing 2, the lower part of the shift block is limited by the fixed block 71 and cannot rotate downward. At this time, the lever 66 will drive the rotating rod 63 to rotate a certain angle, so that the arc 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; During the rising process of the slider 61, the lever 66 on the rotating rod 63 contacts the lever block located below the casing 2. The lever block can rotate upward without causing the rotating rod 63 to rotate. The slider 61 rises, and the arc scraper 64 is always in an inclined state, so the liquid phase will not be scraped to the top of the inner wall of the casing 2 again. When the lever 66 contacts the lever block located above the casing 2 again, the upper part of the lever block is limited by the fixed block 71 and cannot rotate upward. At this time, the lever 66 will drive the rotating rod 63 to restore the previous rotation angle, so that the arc scraper 64 is in a horizontal state, and the outer wall of the circular scraper is again attached to the inner wall of the casing 2, and the liquid phase is not allowed to pass through, so that the liquid phase can continue to be scraped to the bottom of the casing 2.

[0033] During the rotation of the rotating rod 63, since a sliding rod 68 is provided 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 restoring the extended state after the rotating rod 63 rotates a certain angle, so that the sliding rod 68 is stuck in another third opening 610, thereby quickly completing the locking of the rotation angle of the arc scraper 64 in the first opening 65.

[0034] The above process is a cycle in which the arc scraper 64 reciprocates 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 casing 2 can be completely collected, and a baffle 8 is provided in the chute 29, so that the liquid phase will not further penetrate into the chute 29. Even if there is some penetration, the arc scraper 64 is close to the inner wall of the casing 2 when it descends during the scraping process, and the airflow can push the liquid phase in the chute 29 to flow downward.

[0035] During the up and down reciprocating sliding process, the slider 61 will continuously contact the upper part of the cross block 210, slightly compressing the compression spring 25, which can cause the bottom of the drum 24 to vibrate. On the one hand, it can shake the materials separated between the outer drum 26 and the inner drum 27 to facilitate the collection of the 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.

[0036] Specifically, an oblique opening is provided below the chute 29 to facilitate the outflow of the liquid phase.

[0037] Specifically, a mother liquid port 21 is provided on one side of the housing 2 for discharging the liquid phase.

[0038] Specifically, an opening for accommodating the transmission belt 4 is provided at the bottom of the housing 2 .

[0039] When the centrifuge of the present invention is working, the basket cover 28 is taken out, and the separated material is 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 material is gradually added to 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 material, so that the separated material 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 material 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.

[0040] After the feeding is completed, the screw 52 is rotated, and the wedge block 54 is pushed into the inside of the rotating shaft 3 through the rotating sleeve 53. Since a bevel matching the shape of the wedge block 54 is provided on one side of the rotating shaft 3, no matter how much the feeding is and how high the final sinking height of the drum bottom 24 is, as long as the deformation of the compression spring 25 is kept within the pre-set elastic range, the wedge block 54 can continuously extend into the rotating shaft 3 through the wedge-shaped fit during the inward pushing process, ensuring that the drum bottom 24 can lock the rotating shaft 3, facilitating the subsequent centrifugal separation work; The basket cover 28 is fixed to the outer drum 26 and the inner drum 27 by bolts, and the two semicircular plates 23 are sealed to the upper end of the casing 2 by bolts, and the motor 12 on the fixing seat 11 is started, and then the shaft 3, the drum bottom 24, the inner drum 27 and the outer drum 26 are driven to rotate by the transmission belt 4, and the liquid phase is discharged from the filtering holes on the outer drum 26 and discharged to the outside of the casing 2 through the mother liquid port 21. A water retaining ring can also be provided on the upper end of the outer drum 26 to prevent the separated liquid from splashing.

[0041] When unloading after dehydration, manually remove the bolts, take out the machine cover 22 and basket cover 28 in turn, and then take out the materials. Since the inner wall of the casing 2 will have residual liquid after centrifugal separation, it needs to be scraped out by the scraper assembly 6. By rotating the screw 52, ​​the fixing 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 slide groove 29 on the inner wall of the casing 2. During the first downward movement of the slider 61, the lever 66 on the rotating rod 63 contacts the lever block in the adjustment assembly 7 located above the casing 2, and the lever block can be rotated downward. , and then the second spring 73 on the adjusting rod 72 is reset, the rotating rod 63 will not rotate, the slider 61 drops, and the two arc scrapers 64 can scrape the liquid phase remaining on the inner wall of the casing 2 downward. When the lever 66 contacts the shift block located below the casing 2, the lower part of the shift block is limited by the fixed block 71 and cannot rotate downward. At this time, the lever 66 will drive the rotating rod 63 to rotate a certain angle, so that the arc 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; During the rising process of the slider 61, the lever 66 on the rotating rod 63 contacts the lever block located below the casing 2. The lever block can rotate upward without causing the rotating rod 63 to rotate. The slider 61 rises normally, and the arc scraper 64 is always in an inclined state, so the liquid phase will not be scraped to the top of the inner wall of the casing 2 again. When the lever 66 contacts the lever block located above the casing 2 again, the upper part of the lever block is limited by the fixed block 71 and cannot rotate upward. At this time, the lever 66 will drive the rotating rod 63 to restore the previous rotation angle, so that the arc scraper 64 is in a horizontal state, and the outer wall of the circular scraper is again attached to the inner wall of the casing 2, and the liquid phase is not allowed to pass through, and the liquid phase can continue to be scraped to the bottom of the casing 2.

[0042] During the rotation of the rotating rod 63, since a sliding rod 68 is provided 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 restoring the extended state after the rotating rod 63 rotates a certain angle, so that the sliding rod 68 is stuck in another third opening 610, and the rotation angle of the arc scraper 64 in the first opening 65 is quickly locked.

[0043] The above process is a cycle in which the arc scraper 64 reciprocates 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 casing 2 can be completely collected, and a baffle 8 is provided in the chute 29, so that the liquid phase will not further penetrate into the chute 29. Even if there is some penetration, the arc scraper 64 is close to the inner wall of the casing 2 when it descends during the scraping process, and the airflow can push the liquid phase in the chute 29 to flow downward.

[0044] As the slider 61 slides back and forth up and down, it will constantly contact the top of the cross block 210, slightly compressing the compression spring 25, which can cause the bottom of the drum 24 to vibrate. On the one hand, it can shake the materials separated between the outer drum 26 and the inner drum 27 to facilitate material collection. On the other hand, it can continue to shake out the residual liquid phase between the materials, further improving the solid-liquid separation effect.

[0045] 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 it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
