Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of small experimental instruments, in particular to a small automatic leveling instrument. Background Art
[0002] A centrifuge is a high-speed instrument that uses centrifugal force to separate the components in a sample. Its centrifugal force simulates the earth's gravity field, causing the particles in the liquid to settle. The sample is separated according to the different sedimentation coefficients and densities of the particles, and the components required for the experiment are obtained. Before using the centrifuge, the sample needs to be loaded into a container and balanced before centrifugation. If the sample is not balanced and placed symmetrically, the torque on the centrifuge shaft will be different. During long-term use, the rotor will cause greater wear on the shaft, which will affect the service life of the centrifuge. At the same time, if the imbalance value is large, it may also cause harm to the laboratory and operators.
[0003] During balancing, the experimenter may be affected by the electronic scale and perform repeated balancing operations. It is also possible that the experimenter reduces weighing and directly performs the balancing operation visually, which may cause wear on the centrifuge during centrifugation and pose certain safety hazards.
[0004] In order to reduce the excessive time wasted on balancing and reduce the potential safety hazards in the laboratory, it is necessary to design a device that can achieve automatic balancing. Summary of the invention

[0007] Preferably, the sample container has an outer shape of an inverted cone.
[0008] Preferably, the first electronic balance and the second electronic balance are both mounted on a base.
[0009] Preferably, the bottom of the support rod is fixed on the base.

[0021] Embodiment 1
[0022] like Figure 1As shown, the utility model provides a small automatic leveling instrument, including a sample container 1 for temporarily storing samples to be leveled. In this embodiment, the sample container 1 is made of stainless steel, and the shape of the sample container 1 is an inverted cone, which can facilitate the smooth discharge of the internal sample.
[0023] The sample container 1 is installed in the housing 2 to protect the sample container 1. An upper cover 3 is provided above the housing 2 to effectively prevent impurities from entering the sample container 1 and to provide protection for the internal structure of the sample container 1.
[0024] A support rod 9 is provided at the bottom of the shell 2, and the bottom of the support rod 9 is fixed on the base 10. The shell 2 can be fixed by the base 10 and the support rod 9, and at the same time, an installation space can be provided for the blanking structure at the bottom of the shell 2.
[0025] A first valve 5 and a second valve 6 are provided at the bottom of the sample container 1. A first pipeline 7 is connected below the first valve 5, and a second pipeline 8 is connected below the second valve 6. The first valve 5 can control the sample flow rate discharged from the first pipeline 7, and the second valve 6 can control the sample flow rate discharged from the second pipeline 8.
[0026] A first electronic balance 11 is provided below the first pipeline 7, and a second electronic balance 12 is provided below the second pipeline 8, for respectively weighing the samples flowing out of the first pipeline 7 and the second pipeline 8. The first electronic balance 11 and the second electronic balance 12 are both mounted on a base 10, which can ensure the fixation of the positions of the first electronic balance 11 and the second electronic balance 12 to prevent them from shifting easily. A first balancing container 13 is provided on the first electronic balance 11, and a second balancing container 14 is provided on the second electronic balance 12. The first balancing container 13 and the second balancing container 14 are centrifuge tubes or centrifuge bottles. The weights of the first balancing container 13 and the second balancing container 14 are the same.
[0027] A display screen 4 is installed on the housing 2 , and the working states of the first valve 5 and the second valve 6 can be controlled through the display screen 4 .
[0028] The working principle is as follows: first, pour the sample to be balanced into the sample container 1 in advance, and place the first balancing container 13 and the second balancing container 14 (centrifuge bottles or centrifuge tubes, if there is a rack for fixing centrifuge tubes, they can be peeled first) below the first pipeline 7 and the second pipeline 8 and above the first electronic balance 11 and the second electronic balance 12, respectively. The first electronic balance 11 and the second electronic balance 12 will display the weight of the first balancing container 13 and the second balancing container 14 respectively. Click Start on the display screen 4, and the two first valves 5 and the second valve 6 will open. The sample in the sample container 1 is added to the first balancing container 13 and the second balancing container 14 through the first pipeline 7 and the second pipeline 8 respectively. According to the weighing weight of the first electronic balance 11 and the second electronic balance 12, the balancer automatically controls the opening of the corresponding first valve 5 and the second valve 6, and balances the samples in the first balancing container 13 and the second balancing container 14, with an error of ±0.01.
[0029] If balancing of fixed weight samples is required, one of the first balancing container 13 or the second balancing container 14 can be selected to hold water of corresponding weight, and the other balancing container is used to hold the sample. The two balancing containers are placed on the corresponding electronic balance, and the operating status of the first valve 5 and the second valve 6 is controlled by the display screen 4, and the corresponding single-pipeline liquid outlet is selected for balancing.
[0030] Before and after the sample balancing work is performed, the sample container 1, the first pipeline 7 and the second pipeline 8 need to be cleaned with pure water. When not in use, the upper cover 3 is covered on the outer shell 2 for storage.
[0031] Therefore, the utility model adopts the above-mentioned small automatic leveling instrument, which has a simple structure and is easy to operate, can effectively improve the experimental speed and reduce the safety hazards of the laboratory.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
