Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a liquid sample separation device. Background Art

[0002] With the development of the times, people's living standards are constantly improving, and people's requirements for living environment are getting higher and higher. With the progress of industrialization, the generation of sewage has become inevitable. Therefore, the treatment of sewage has received more and more attention. The process of sewage treatment is to purify the sewage to meet the water quality requirements for discharge into a certain water body or reuse. Before discharging or meeting the water quality requirements for reuse, in order to ensure the treatment effect, it is necessary to use water quality monitoring equipment to detect whether the treated water quality meets certain standards.

[0003] During the sewage treatment process, in order to improve the convenience of sewage testing, sewage samples are usually placed inside test tubes, and magnetic beads are placed inside the test tubes. The magnetic beads are used to adsorb the sewage samples, and then the magnetic beads are tested, which greatly improves the efficiency of sewage testing.

[0004] It is known that before the sewage sample is tested, a disposable plastic sleeve is placed on the outside of the magnetic rod. Therefore, during use, when the magnetic rod is inserted into the test tube containing the sewage sample and magnetic beads, the magnetic adsorption between the magnetic rod and the magnetic beads can overcome the barrier between the plastic sleeve to generate adsorption force. Therefore, when the magnetic rod slides upward, the magnetic rod can bring out the magnetic beads inside the test tube. However, in the prior art, when the magnetic beads are brought out from the test tube during actual operation, a handheld device is required to remove the magnetic beads from the plastic sleeve, which has certain shortcomings. Utility Model Content

[0005] The purpose of the utility model is to provide a liquid sample separation device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a liquid sample separation device, comprising a shell, a mounting frame installed in the shell, a fixed frame slidably connected to the mounting frame, a second bracket fixedly connected to the fixed frame, and a plurality of groups of plastic tubes installed on the second bracket; a first bracket slidably connected to the fixed frame, a plurality of groups of magnetic bars installed on the first bracket, each magnetic bar being slidably connected to a corresponding plastic tube; a driving member for driving the fixed frame to slide is provided on the mounting frame; a separating member is also provided between the first bracket and the shell, and when the driving member drives the fixed frame to slide upward, the first bracket is driven to separate from the second bracket through the separating member, so that each magnetic bar slides out of its corresponding plastic tube respectively.

[0007] Furthermore, the driving member includes a driving motor installed on the carrying frame, a driving screw is rotatably connected to the carrying frame, and the driving motor is coaxially connected to the driving screw through a coupling; the fixed frame is slidably connected to the carrying frame through a driving block, and the driving screw is threadedly connected to the driving block.

[0008] Furthermore, an adapting groove is provided on the fixing frame, a limiting block is slidably connected in the adapting groove, and a return spring is provided between the limiting block and the adapting groove.

[0009] Furthermore, the separation component includes a transmission rod rotatably connected to the shell, and a first gear and a second gear are installed on the transmission rod, and the number of teeth of the first gear and the second gear are different; an extension plate is fixedly connected to the limit block, and a first rack is fixedly connected to the extension plate, and the first rack is meshed with the first gear; a connecting plate is fixedly connected to the fixed frame, and a second rack is fixedly connected to the connecting plate, and the second rack is meshed with the second gear.

[0010] Furthermore, a plurality of groups of the plastic tubes are mounted on the second bracket via a clamping member.

[0011] Furthermore, the clamping member comprises a mounting groove provided on the second bracket, each mounting groove is provided with a mounting bar which is slidingly connected with damping, and each of the plastic tubes is respectively mounted on the bottom of the corresponding mounting bar.

[0012] Furthermore, a protective door is rotatably connected with damping on the outer side of the shell.

[0013] Compared with the prior art, the beneficial effects of the utility model are: the liquid sample separation device, after processing is completed, drives the fixed frame to slide through the driving member, and the fixed frame drives the first bracket and the second bracket to slide upward synchronously. When the feed tube slides out of the test tube, the supporting plate inside the shell is slid out, and the collection plate for collecting magnetic beads is replaced, and then the mounting frame is continuously driven to slide upward through the driving member. After the mounting frame slides to a predetermined position, the first bracket and the second bracket are gradually separated by the separating member. Therefore, in the travel of the fixed frame continuously sliding upward, the first bracket and the second bracket will continue to separate, that is, the magnetic rod will separate from the plastic tube. Therefore, the adsorbed magnetic beads located on the outside of the plastic tube will fall off the collection plate by themselves when they lack magnetic adsorption force, and then they can be detected on the magnetic beads. Therefore, there is no need to disassemble the magnetic beads through equipment in the outside world, which meets work needs. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6The utility model provides a technical solution: a liquid sample separation device, comprising a shell 1, a mounting frame 2 is installed in the shell 1, a fixing frame 7 is slidably connected to the mounting frame 2, a second bracket 5 is fixedly connected to the fixing frame 7, and a plurality of plastic tubes 10 are installed on the second bracket 5; a first bracket 3 is slidably connected to the fixing frame 7, a plurality of magnetic rods 9 are installed on the first bracket 3, and each magnetic rod 9 is slidably connected to the corresponding plastic tube 10; a driving member 4 for driving the fixing frame 7 to slide is arranged on the mounting frame 2; a separation member is also arranged between the first bracket 3 and the shell 1, and when the driving member 4 drives the fixing frame 7 to slide upward, the first bracket 3 is driven to separate from the second bracket 5 through the separation member, so that each magnetic rod 9 slides out of its corresponding plastic tube 10 respectively.

[0024] Specifically, the liquid sample separation device includes a housing 1, wherein a bearing plate is slidably connected inside the housing 1, wherein a plurality of test tubes containing sewage samples are arranged on the bearing plate, and each test tube is filled with a plurality of magnetic beads at the same time. More specifically, a mounting frame 2 is installed inside the housing 1, a fixed frame 7 is slidably connected to the mounting frame 2, a second bracket 5 is fixedly connected to the fixed frame 7, and a plurality of plastic tubes 10 are installed on the second bracket 5, wherein the plastic tubes 10 are disposable. And a first bracket 3 is slidably connected to the fixed frame 7, and a plurality of magnetic rods 9 are installed on the first bracket 3, and each magnetic rod 9 is slidably connected to the corresponding plastic tube 10. A driving member 4 for driving the fixed frame 7 to slide is arranged on the mounting frame 2, so that when in use, the driving member 4 drives the fixed frame 7 to slide downward, so that each magnetic rod 9 is respectively inserted into the corresponding plastic tube 10, and then inserted into the test tube through the plastic tube 10. At the same time, a vibration motor is arranged inside the housing 1, which is used to drive the bearing frame to vibrate, and can drive a plurality of magnetic rods 9 to vibrate in their corresponding test tubes to meet the work needs. A separation member is also provided between the first bracket 3 and the housing 1. When the driving member 4 drives the fixing frame 7 to slide upward, the separation member drives the first bracket 3 to separate from the second bracket 5, so that each magnetic rod 9 slides out of its corresponding plastic tube 10. Therefore, after the processing is completed, the fixing frame 7 is driven to slide by the driving member 4, and the fixing frame 7 drives the first bracket 3 and the second bracket 5 to slide upward synchronously. When the feeding tube slides out from the test tube, the supporting plate inside the shell 1 is slid out, and the collecting plate for collecting magnetic beads is replaced. Then, the mounting frame 2 is continuously driven to slide upward by the driving member 4. After the mounting frame 2 slides to a predetermined position, the first bracket 3 and the second bracket 5 are gradually separated by the separating member. Therefore, during the upward sliding stroke of the fixing frame 7, the first bracket 3 and the second bracket 5 will continue to separate, that is, the magnetic rod 9 will separate from the plastic tube 10. Therefore, the adsorbed magnetic beads located on the outside of the plastic tube 10 will fall off the collecting plate by themselves when they lack magnetic adsorption force, and then they can be detected on the magnetic beads. Therefore, there is no need to disassemble the magnetic beads through equipment in the outside world, which meets the work needs.

Therefore, during use, the driving motor drives the driving screw to rotate, which can drive the driving block 6 to slide, and then drive the fixed frame 7 to slide, meeting work needs.

[0026] In the embodiment provided by the utility model, an adapting groove is provided on the fixing frame 7, a limit block 8 fixedly connected to the first bracket 3 is slidably connected in the adapting groove, a reset spring 19 is provided between the limit block 8 and the adapting groove, wherein the elastic force of the reset spring 19 can make the first bracket 3 more stable when in use. When the first bracket 3 is separated from the second bracket 5, the reset spring 19 needs to be driven to deform to overcome the elastic force of the reset spring 19 to meet the working needs.

[0027] In the embodiment provided by the utility model, the separation component includes a transmission rod 18 rotatably connected to the housing 1, and a first gear 15 and a second gear 16 are installed on the transmission rod 18, and the number of teeth of the first gear 15 and the second gear 16 are different; an extension plate 13 is fixedly connected to the limit block 8, and a first rack 14 is fixedly connected to the extension plate 13, and the first rack 14 is meshed with the first gear 15; a connecting plate 20 is fixedly connected to the fixed frame 7, and a second rack 17 is fixedly connected to the connecting plate 20, and the second rack 17 is meshed with the second gear 16. Therefore, after the fixed frame 7 slides upward for a certain distance, the second rack 17 at this moment will mesh with the second gear 16, and then can drive the transmission rod 18 to rotate, and when the first rack 14 is meshed with the first gear 15, it will drive the first rack 14 to slide upward to meet the working needs. Since the first gear 15 and the second gear 16 have different numbers of teeth, the sliding speeds of the first rack 14 and the second rack 17 will change due to the transmission ratio. As the fixing frame 7 continues to slide, the first bracket 3 and the second bracket 5 will separate to meet working needs.

[0028] In the embodiment provided by the utility model, multiple groups of plastic tubes 10 are installed on the second bracket 5 through the clamping parts, so as to facilitate the installation and removal of the plastic tubes 10.
