Description

Technical Field

[0001] The invention relates to the field of refrigerated centrifuges, in particular to a condensed water storage and evaporation device for a refrigerated centrifuge, a refrigerated centrifuge and a method. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] A centrifuge is a machine that uses centrifugal force to accelerate the separation of different materials that need to be separated. Refrigerated centrifuges are often used for a large number of primary separations and extractions of biological macromolecules, sediments, etc. Refrigerated centrifuges use the centrifugal force generated by the high-speed rotation of the rotor to accelerate the sedimentation rate of particles in the liquid, separate substances with different sedimentation coefficients and buoyancy densities in the sample, and control the temperature of the inner cavity where the rotor is located within an ideal range through its own system, thereby protecting temperature-sensitive samples and preventing the samples from losing activity or denaturing. Refrigerated centrifuges contain a refrigeration system. When using a refrigerated centrifuge for low-temperature centrifugation, the inner cavity will frost or freeze due to the decrease in temperature. When the machine opens the cover or turns off the power after centrifugation, the temperature of the inner cavity will rise and a certain amount of condensed water will be generated. Since the inner cavity of existing refrigerated centrifuges on the market lacks treatment for condensed water or the treatment method is imperfect, when too much condensed water accumulates and the time is too long, it will not only easily cause the inner cavity to rust, but also cause bacteria to grow in the inner cavity, thus affecting the quality of the sample;

[0004] For this reason, the existing treatment method is that after condensed water is generated in the inner cavity, the inner cavity needs to be wiped clean manually, which is time-consuming, labor-intensive, and untimely. In addition, if the condensed water is not cleaned for too long, the cleaning process is more complicated and the cleaning effect is poor. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a condensed water storage and evaporation device for a refrigerated centrifuge, which can eliminate the problem of condensed water remaining after the centrifugation of the refrigerated centrifuge, realize the storage and evaporation of condensed water, and avoid the problem of rusting of the inner cavity due to condensed water and cleaning of condensed water.

[0006] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0007] A condensed water storage and evaporation device for a refrigerated centrifuge comprises an evaporation device, the evaporation device is located inside the refrigerated centrifuge body, the evaporation device is connected to the bottom of an inner cavity of the refrigerated centrifuge through a connecting pipeline so that condensed water in the inner cavity flows into the evaporation device, a compressor exhaust port copper pipe is arranged through the interior of the evaporation device, and during the operation of the compressor, the exhaust port copper pipe transfers heat to the condensed water in the evaporation device so that the condensed water in the evaporation device evaporates; a water level sensor is arranged in the evaporation device, and the water level sensor is connected to a control switch of the compressor.

[0008] In the condensed water storage and evaporation device for a refrigerated centrifuge as described above, the exhaust copper tube has multiple bending sections so that part of the exhaust copper tube enters the evaporation device.

[0009] In the condensed water storage and evaporation device for a refrigerated centrifuge as described above, the portion of the exhaust port copper tube located in the evaporation device is bent into multiple sections to increase the contact area with the condensed water in the evaporation device.

[0010] In the condensed water storage and evaporation device for a refrigerated centrifuge as described above, the exhaust port copper tube includes a first section, a second section and a third section connected in sequence, the first section is connected to the compressor, the second section is located in the evaporation device, the third section is connected to the condenser, and the plane where the second section is located is perpendicular to the plane where the third section is located.

[0011] In the above-mentioned condensed water storage and evaporation device for a refrigerated centrifuge, a fixing frame is arranged in the evaporation device, and the second section of the exhaust copper tube is fixed by the fixing frame, so that the second section of the exhaust copper tube is fixed in the evaporation device by the fixing frame.

[0012] In the condensed water storage and evaporation device for a refrigerated centrifuge as described above, the middle portion of the connecting pipe is first bent upward and then bent downward to form an annular tube. The arc tube serves the purpose of temporarily storing condensed water and avoids affecting the temperature in the inner cavity of the refrigerated centrifuge, thereby preventing the liquid in the evaporation device from entering the inner cavity of the refrigerated centrifuge.

[0013] In the condensed water storage and evaporation device for a refrigerated centrifuge as described above, the evaporation device is detachably connected to the bottom of the refrigerated centrifuge body, so that the evaporation device can be conveniently installed in an existing refrigerated centrifuge.

[0014] In the above-mentioned condensed water storage and evaporation device for a refrigerated centrifuge, the evaporation device is arranged in an open manner.

[0015] In a second aspect, the present invention further provides a refrigerated centrifuge, including the condensed water storage and evaporation device of a refrigerated centrifuge, including a refrigerated centrifuge body, the refrigerated centrifuge body supports the inner cavity of the refrigerated centrifuge, a drainage hole is arranged at the bottom of the inner cavity of the refrigerated centrifuge, the drainage hole is connected to the evaporation device, and the evaporation device is located below the inner cavity of the refrigerated centrifuge.

[0016] In a third aspect, the present invention provides a working method of a condensed water storage and evaporation device for a refrigerated centrifuge, comprising the following contents:

[0017] After the refrigerated centrifuge is powered off, the temperature in the inner cavity of the refrigerated centrifuge returns to normal, condensed water is generated in the inner cavity of the refrigerated centrifuge, and the condensed water flows into the evaporation device;

[0018] The water level sensor in the evaporation device obtains the water level information in the evaporation device and sends it to the compressor. The compressor starts working. During the operation of the compressor, the copper tube at the compressor exhaust port releases heat to evaporate the condensed water in the evaporation device.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1) The present invention discharges the condensed water generated in the inner cavity of the refrigerated centrifuge into the evaporation device, and the copper tube of the compressor exhaust port is arranged through the inside of the evaporation device. In this way, during the operation of the compressor, the heat of the copper tube of the exhaust port (a high-pressure tube, which has a higher temperature during operation and carries the high-temperature refrigerant just discharged from the compressor) is utilized to evaporate the condensed water in the evaporation device. In this way, the problem of condensed water in the inner cavity of the refrigerated centrifuge needing to be cleaned is avoided, and there is no need for staff to handle the condensed water, thereby reducing labor intensity. In addition, the condensed water is treated by evaporation of the compressor, and the treatment effect is good and the treatment efficiency is high.

[0021] 2) The present invention sets a water level sensor in the evaporation device. When the condensed water in the evaporation device reaches the set water level, the water level sensor will send a signal. The compressor that receives the signal discharges high-pressure hot air through the copper tube and starts to evaporate the condensed water in the evaporation device, thereby realizing automatic processing of the condensed water in the evaporation device without the need for staff to participate in the processing.

[0022] 3) In the present invention, a ring pipe is arranged in the middle of the connecting pipe, and the condensed water discharged from the inner cavity of the refrigerated centrifuge will gather at the ring pipe of the connecting pipe. When the connecting pipe stores a set amount of condensed water, a water seal is formed, which effectively avoids the external air from interacting with the air in the inner cavity of the refrigerated centrifuge and avoiding affecting the temperature in the inner cavity of the refrigerated centrifuge.

[0023] 4) The exhaust port copper tube in the present invention includes multiple sections, namely the first section, the second section and the third section. The first section is connected to the compressor, and the second section is bent into multiple sections to increase the contact area between the second section of the exhaust port copper tube and the condensed water, which is beneficial to the rapid evaporation of the condensed water. The third section connects the second section to the condenser to ensure the original setting purpose of the exhaust port copper tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0032] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless otherwise explicitly stated in the present invention, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof;

[0033] As introduced in the background technology, the condensed water generated in the inner cavity of the refrigerated centrifuge in the prior art has the problem of unchanged treatment. In order to solve the above technical problem, the present invention proposes a condensed water storage and evaporation device for a refrigerated centrifuge.

[0034] Embodiment 1

[0035] In a typical embodiment of the present invention, reference is made to Figure 1 As shown, a condensed water storage and evaporation device for a refrigerated centrifuge includes an evaporation device 6, which is located inside a refrigerated centrifuge body 1. The evaporation device 6 is connected to the bottom of the inner cavity of the refrigerated centrifuge through a connecting pipe 5 so that the condensed water in the inner cavity flows into the evaporation device 6. The compressor exhaust copper tube 4 is arranged inside the evaporation device 6. During the operation of the compressor 3, the exhaust copper tube 4 transfers heat to the condensed water in the evaporation device 6 to evaporate the condensed water in the evaporation device 6.

[0036] To further facilitate the automatic processing of condensed water, a water level sensor 7 is provided in the evaporation device 6. The water level sensor 7 is an existing water level gauge. The water level sensor 7 is connected to the control switch of the compressor 3. Thus, even when the compressor is not working, the water level sensor 7 obtains the water level information in the evaporation device 6 and sends the obtained water level information to the controller. The controller is an existing controller of the refrigerated centrifuge body. When the water level information in the evaporation device reaches the set value, the controller can send information to the control switch of the compressor 3 to control the compressor to start alone.

[0037] Alternatively, the water level sensor 7 is connected to a control component, which is a PLC controller or other types of controllers, and the control component is connected to a control switch of the compressor 3 , and the control component can be supported by the refrigerated centrifuge body 1 .

[0038] It is easy to understand that the exhaust copper tube 4 has multiple bending sections so that part of the exhaust copper tube 4 enters the evaporation device 6, and the part of the exhaust copper tube 4 located in the evaporation device is bent in multiple sections to increase the contact area with the condensed water in the evaporation device.

[0039] In this embodiment, the exhaust copper tube 4 includes a first section 4-1, a second section 4-2 and a third section 4-3 which are connected in sequence, the first section 4-1 is connected to the compressor 3, the second section 4-2 is located in the evaporation device 6, the second section 4-2 is arranged in a horizontal plane, the third section 4-3 is connected to the condenser, and the plane where the second section 4-2 is located is perpendicular to the plane where the third section 4-3 is located.

[0040] In some examples, the first section 4-1 of the exhaust copper tube 4 is first bent downward, then bent upward, and finally reaches one side of the evaporator 6 to be connected to one end of the second section 4-2. In this way, the first section 4-1 includes a U-shaped tube and an L-shaped tube, and the second section includes multiple U-shaped tubes connected in sequence. The other end of the second section is connected to the third section 4-3, and the third section is L-shaped.

[0041] In addition, it is easy to understand that a fixing frame 4-4 is provided in the evaporation device 6, and the fixing frame 4-4 is specifically a fixing plate. The fixing frame 4-4 is provided along the width direction of the evaporation device. The fixing frame can be provided at two or more locations, and a distance is set between two adjacent fixing frames 4-4. The second section 4-2 of the exhaust copper tube 4 is fixed by the fixing frame 4-4, so that the second section 4-2 of the exhaust copper tube is fixed in the evaporation device by the fixing frame 4-4.

[0042] In this embodiment, the evaporation device 6 is connected to the bottom of the inner cavity 2 of the refrigerated centrifuge through a connecting pipe 5. The connecting pipe 5 refers to the middle part of the connecting pipe between the evaporation device and the inner cavity 2 of the refrigerated centrifuge, which is bent upward to form a circle and then goes down to the evaporation device 6, that is, a ring pipe 5-1 is arranged in the middle of the connecting pipe. The ring pipe 5-1 serves the purpose of temporary storage and prevents the liquid in the evaporation device from entering the inner cavity of the refrigerated centrifuge. When a set amount of condensed water is stored in the ring pipe 5-1 of the connecting pipe 5, a water seal is formed, which effectively prevents the external air from interacting with the air in the inner cavity 2 of the refrigerated centrifuge, and avoids affecting the temperature in the inner cavity 2 of the refrigerated centrifuge.

[0043] It is understandable that the connecting pipe 2 is made of antibacterial material; the refrigerated centrifuge is used every day, and even if too much condensed water accumulates in the annular tube 5-1, when the condensed water in the inner cavity 2 of the refrigerated centrifuge flows into the evaporation device 6 through the annular tube 5-1, the water source flows, the water exchange efficiency is improved, and the risk of bacteria generation is effectively reduced.

[0044] The evaporation device 6 is an evaporation dish, which is open. The material of the evaporation device 6 can be stainless steel. The length of the evaporation device 6 is smaller than the width of the refrigerated centrifuge body, and the width of the evaporation device is smaller than the distance between the compressor 3 and the condenser.

[0045] It is easy to understand that the evaporation device 6 is detachably connected to the bottom of the refrigerated centrifuge body 1, and the evaporation device is specifically installed through the inner surface of the bottom plate of the refrigerated centrifuge body 1. The evaporation device 6 has a set height. The evaporation device 6 is set using the space between the compressor 3 and the condenser. Mounting protrusions are respectively provided on both sides of the evaporation device 6, and mounting holes are provided at the mounting protrusions. Fasteners such as bolts pass through the mounting holes and are detachably connected to the refrigerated centrifuge body 1, so that it is convenient to install the evaporation device in the existing refrigerated centrifuge.

[0046] In addition, to avoid shaking of the connecting pipe 5, the top of the connecting pipe 5 can be connected to the inner cavity 2 of the refrigerated centrifuge through a threaded structure, and a fixing ear is provided at a section of the connecting pipe 5 inserted into the evaporating device 6. The fixing ear has an arc-shaped portion, which is adapted to the connecting pipe 5. Both sides of the fixing ear are connected to the side walls of the evaporating device 6, and the bottom of the connecting pipe is fixed to the evaporating device 6 through the fixing ear.

[0047] The water storage evaporation device provided in this embodiment discharges the condensed water generated in the inner cavity 2 of the refrigerated centrifuge into the evaporation device 6. The compressor exhaust port copper tube 4 is arranged to pass through the inside of the evaporation device 6. In this way, during the operation of the compressor 3, the heat of the exhaust port copper tube 4 (a high-pressure tube, which has a higher temperature when working and carries the high-temperature refrigerant just discharged from the compressor) is utilized to evaporate the condensed water in the evaporation device 6. In this way, there is no need for the staff to handle the condensed water, thereby reducing the labor intensity.

The compressor is located below the refrigerated centrifuge inner cavity 2, and a drainage hole is arranged at the bottom (at the lowest end position) of the refrigerated centrifuge inner cavity 2, so that the condensed water generated by the refrigerated centrifuge inner cavity 2 can be effectively discharged, and the drainage hole is connected to the evaporation device 6 through a connecting pipe 5, and the evaporation device is located below the refrigerated centrifuge inner cavity.
