Description

Technical Field

[0001] This application relates to the field of extraction equipment technology, and in particular to a centrifugal extractor. Background Technology

[0002] Centrifugal extractors are extraction devices that achieve rapid phase separation based on centrifugal force fields. They are mainly divided into stirred type, annular gap type and direct-drive type, and are widely used in pharmaceutical, metallurgical, wastewater treatment, nuclear fuel reprocessing and petrochemical fields. They achieve efficient separation by the ratio of centrifugal acceleration to gravitational acceleration (usually hundreds to thousands, and a few up to tens of thousands). They are suitable for systems with small density differences and high viscosity between the two phases and for non-equilibrium extraction needs.

[0003] While existing centrifugal extractors can effectively extract liquids, when using a receiving bottle to assist in centrifugal extraction, the receiving bottle is often placed directly into the infusion path of the infusion tube. The clamping and fixing effect of the receiving bottle is not high, and when the receiving bottle is loosened, the protective block provided poor support for the end of the infusion tube, which can easily lead to dripping from the end of the infusion tube and waste of the extracted liquid. Utility Model Content

[0004] To address the aforementioned issues of ineffective clamping and securing of the receiving bottle onto the placement surface, and the poor protection provided by the drive protective block to the end of the infusion tube when the receiving bottle is detached, resulting in waste of extracted liquid, this application provides a centrifugal extractor.

[0005] The centrifugal extractor provided in this application adopts the following technical solution: it includes a placement plate, a support rod is provided on the outer wall of the placement plate, a centrifugal extraction tank is installed on the outer wall of the support rod by a fixing rod, a support block is installed on the outer wall of the support rod by a fixing rod that fits against the bottom of the centrifugal extraction tank, an infusion tube is provided at the bottom of the centrifugal extraction tank, and a receiving bottle located below the infusion tube is placed on the outer wall of the placement plate.

[0006] The outer wall of the placement plate is provided with a protective mechanism, which includes a clamping block, a sliding rod, and a protective block.

[0007] The outer wall of the placement plate is rotatably connected to a threaded rod, and the outer wall of the threaded rod is threadedly connected to a clamping block that is slidably connected to the outer wall of the placement plate. The outer wall of the placement plate is rotatably connected to a swing rod, and the outer wall of the swing rod is slidably connected to a sliding rod that is slidably connected to the outer wall of the placement plate. The top of the sliding rod is fixedly connected to a protective block located on one side of the infusion tube.

[0008] By adopting the above technical solution, when collecting the extracted liquid through the receiving bottle, in order to improve the stability of the receiving bottle on the placement plate and to shield and protect the liquid that may drip from the end of the infusion tube when the receiving bottle is loosened, the clamping block moves away from the receiving bottle. As it moves, the connecting rod slides along the inner wall of the first limiting groove, driving the swing rod to rotate. The rotation of the swing rod drives the sliding rod to slide synchronously along the inner wall of the second limiting groove and the sliding groove, so that the protective block moves to the bottom of the infusion tube, achieving the effect of receiving and protecting the liquid that may drip.

[0009] Preferably, the threaded rod is provided in two sets, and the two sets of threaded rods rotate in opposite directions.

[0010] By adopting the above technical solution, the clamping blocks can slide relative to each other.

[0011] Preferably, one end of the threaded rod is fixedly connected to a knob, the outer wall contour of the clamping block is arc-shaped, and the clamping block is symmetrically arranged about the central axis of the receiving bottle.

[0012] By adopting the above technical solution, the stability of the receiving bottle placed on the placement plate is improved.

[0013] Preferably, the outer wall of the clamping block is fixedly connected to a connecting rod that is slidably connected to the outer wall of the swing rod, and a first limiting groove is provided at the connection between the outer wall of the swing rod and the connecting rod.

[0014] By adopting the above technical solution, the effect of driving the swing arm to rotate conveniently can be achieved.

[0015] Preferably, a second limiting groove is provided at the connection between the outer wall of the swing rod and the sliding rod, and a sliding groove is provided at the connection between the outer wall of the placement plate and the sliding rod.

[0016] By adopting the above technical solution, the effect of driving the sliding rod to limit its sliding is achieved.

[0017] Preferably, the protective block is inclined, and the movement distance of the protective block is the same as the movement distance of the clamping block.

[0018] By adopting the above technical solution, a convenient protection can be provided for liquid dripping from the infusion tube.

[0019] Preferably, the bottom of the placement plate has an installation hole, the inner wall of the installation hole is threaded with a rubber fixing pad, the outer wall of the rubber fixing pad is provided with an outer spiral, and the inner wall of the installation hole is provided with an inner spiral that is threaded with the outer wall of the outer spiral.

[0020] By adopting the above technical solutions, the stability of the placement board when placed on the desktop is improved.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. By utilizing the telescopic movement of the protective block, when collecting the extracted liquid through the receiving bottle, in order to improve the stability of the receiving bottle on the placement plate and to shield and protect the liquid that may drip from the end of the infusion tube when the receiving bottle is released, the clamping block moves away from the receiving bottle and slides along the inner wall of the first limiting groove via the connecting rod, driving the swing rod to rotate. The rotation of the swing rod drives the sliding rod to slide synchronously along the inner wall of the second limiting groove and the sliding groove, so that the protective block moves to the bottom of the infusion tube, achieving the effect of receiving and protecting the liquid that may drip.

[0023] 2. By using rubber fixing pads, the placement board is placed on the table. To improve the stability of the placement board, the rubber fixing pads are installed into the mounting holes through the external and internal spiral threaded connection, thereby improving the stability of the placement board on the placement surface.

[0029] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0030] This application discloses a centrifugal extractor.

[0031] Reference Figures 1-3A centrifugal extractor includes a placement plate 1, a support rod 2 on the outer wall of the placement plate 1, a centrifugal extraction tank 3 mounted on the outer wall of the support rod 2 via a fixing rod, a support block 4 mounted on the outer wall of the support rod 2 via a fixing rod and fitting against the bottom of the centrifugal extraction tank 3, an infusion tube 5 at the bottom of the centrifugal extraction tank 3, and a receiving bottle 6 located below the infusion tube 5 placed on the outer wall of the placement plate 1.

[0032] The outer wall of the placement plate 1 is provided with a protective mechanism, which includes a clamping block 9, a sliding rod 13 and a protective block 16.

[0033] A threaded rod 7 is rotatably connected to the outer wall of the placement plate 1. A clamping block 9 is slidably connected to the outer wall of the placement plate 1 via a threaded connection to the outer wall of the threaded rod 7. A swing rod 11 is rotatably connected to the outer wall of the placement plate 1. A sliding rod 13 is slidably connected to the outer wall of the swing rod 11 via a sliding connection to the outer wall of the placement plate 1. A protective block 16 located on one side of the infusion tube 5 is fixedly connected to the top of the sliding rod 13.

[0034] Reference Figure 3 There are two sets of threaded rods 7, and the two sets of threaded rods 7 rotate in opposite directions. This is beneficial to achieve the effect of driving the two sets of clamping blocks 9 to slide relative to each other by setting the threaded rods 7 with opposite rotation directions.

[0035] Reference Figure 3 A knob 8 is fixedly connected to one end of the threaded rod 7. The outer wall of the clamping block 9 is arc-shaped, and the clamping block 9 is symmetrically arranged about the central axis of the receiving bottle 6. This facilitates the convenient rotation of the threaded rod 7 by using the knob 8.

[0036] Reference Figure 3 The outer wall of the clamping block 9 is fixedly connected to a connecting rod 10 that is slidably connected to the outer wall of the swing rod 11. A first limiting groove 12 is provided at the connection between the outer wall of the swing rod 11 and the connecting rod 10, which facilitates the swing rod 11 to rotate easily through the setting of the connecting rod 10.

[0037] Reference Figure 3 The outer wall of the swing rod 11 is provided with a second limiting groove 14 at the connection between it and the sliding rod 13, and the outer wall of the placement plate 1 is provided with a sliding groove 15 at the connection between it and the sliding rod 13. This facilitates the sliding of the sliding rod 13 by setting the second limiting groove 14 and the sliding groove 15.

[0038] Reference Figure 3 The protective block 16 is set at an angle, and the movement distance of the protective block 16 is the same as that of the clamping block 9. This makes it easier to prevent the end of the infusion tube 5 from dripping by setting the protective block 16 at an angle.

[0039] Reference Figure 4The bottom of the mounting plate 1 has a mounting hole 18. A rubber fixing pad 19 is threaded to the inner wall of the mounting hole 18. An outer spiral 20 is provided on the outer wall of the rubber fixing pad 19. An inner spiral 17 is threaded to the outer wall of the mounting hole 18. The setting of the rubber fixing pad 19 helps to improve the stability of the mounting plate 1 on the placement plane.

[0040] The working principle of this centrifugal extractor is as follows: When collecting the extracted liquid through the receiving bottle 6, in order to improve the stability of the receiving bottle 6 on the placement plate 1 and to protect the liquid that may drip from the end of the infusion tube 5 when the receiving bottle 6 is released, the clamping block 9 moves away from the receiving bottle 6 and slides along the inner wall of the first limiting groove 12 through the connecting rod 10, which drives the swing rod 11 to rotate. The rotation of the swing rod 11 drives the sliding rod 13 to slide synchronously along the inner wall of the second limiting groove 14 and the sliding groove 15, so that the protective block 16 moves to the bottom of the infusion tube 5, thereby achieving the effect of receiving and protecting the liquid that may drip.

[0041] When the placement board 1 is placed on the desktop, in order to improve the stability of the placement board 1, the rubber fixing pad 19 is installed into the mounting hole 18 through the threaded connection of the outer screw 20 and the inner screw 17, thereby improving the stability of the placement board 1 on the placement surface.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
