Description

Prolonged exposure to trichloroethylene can lead to various health issues, such as neurological damage and respiratory problems.

[0035] A high-efficiency centrifugal extraction instrument capable of equal multiple feeding, comprising a base 1, a centrifugal device 2 and a liquid feeding device 3 arranged in sequence from bottom to top;
[0036] The liquid feeding device 3 comprises a material collecting hopper 31 and a plurality of feeding pipes 32;
[0037] The upper end of the material collecting hopper 31 is a discharging port, the lower end of the material collecting hopper 31 is a material collecting port, a cover 33 is movably installed on the discharging port, the discharging port is used for adding external material, and the material collecting hopper 31 is communicated with the centrifugal device 2 through the material collecting port;
[0038] The upper end of the plurality of feeding pipes 32 is a feeding port, the lower end of the plurality of feeding pipes 32 is a discharging port, the plurality of feeding pipes 32 are installed in the interior of the material collecting hopper 31 in a flush manner, the plurality of feeding ports are arranged in a flush manner with the discharging port, the plurality of discharging ports are located in the interior of the material collecting hopper 31, and the plurality of feeding ports are used for adding external solution;
[0039] An adjusting rod 4 is fixedly connected to the middle of the multiple feeding tubes 32. One end of the adjusting rod 4 passes through the collecting hopper 31 and extends to the outside of the collecting hopper 31. An adjusting knob 5 is installed to control the flow rate of the multiple discharge ports.
[0040] The lower end of the collecting hopper 31 is a collecting port, and the collecting hopper 31 is connected to the centrifugal device 2 through the collecting port;
[0041] A driving device 6 is installed inside the base 1. The starting end of the driving device 6 is electrically connected to the starting button 7 through an electric wire. The starting button 7 is arranged on the outside of the base 1. The driving end of the driving device 6 is connected to the centrifugal device 2. The driving device 6 is used to drive the centrifugal device 2 to rotate. The rotation of the centrifugal device 2 is used to rotate and separate the material and solution inside and collect the separated solution.
[0042] like Figures 1-3 As shown, this high-efficiency centrifugal extractor consists of three parts: base 1, centrifugal device 2 and liquid adding device 3. Its working principle is as follows:
[0043] First, the liquid adding device 3 includes a hopper 31 and multiple feeding pipes 32. The upper end of the hopper 31 is designed as a discharge port for operators to add materials, such as asphalt mixture; and the upper ends of these feeding pipes 32 are designed as feeding ports for operators to add solutions, such as trichloroethylene, and the discharge port at the lower end of the feeding pipe 32 is set inside the hopper 31 to ensure that the material and solution can flow smoothly into the hopper 31. Furthermore, an adjusting rod 4 is fixedly inserted in the middle of each feeding pipe 32, one end of which penetrates the wall of the hopper 31 and extends to the outside, and an adjusting knob 5 is installed at the end. This design allows the operator to easily adjust the cross-sectional area of the internal channel of the feeding pipe 32 by rotating the adjusting knob 5, thereby accurately controlling the flow rate and flow rate of the solution discharge port.
[0044] Before the test, the operator can open the cover 33, add asphalt mixture to the aggregate hopper 31, pre-fill multiple feeding tubes 32 with equal amounts of trichloroethylene, and then close the cover 33 to prevent the solution from volatilizing and being thrown out during the centrifugal operation. The operator can then ensure that the solution flows into the aggregate hopper 31 at a constant flow rate by rotating the adjustment knob 5, thereby achieving multiple equal amounts of trichloroethylene addition. The aggregate hopper 31 serves as a temporary storage area for the solution, and its lower end is connected to the centrifugal device 2 through the aggregate port. As the solution accumulates, the material and solution in the aggregate hopper 31 are evenly distributed to the centrifugal device 2 through the aggregate port.
[0045] Secondly, the centrifugal device 2 is located below the liquid adding device 3, which is a key component for material separation. The driving device 6 installed inside the base 1 is connected to the start button 7 outside the base 1 through an electric wire. When the operator presses the start button 7, the driving device 6 starts to work, and its driving end drives the centrifugal device 2 to start high-speed rotation. The trichloroethylene and asphalt mixture in the centrifugal device 2 is quickly mixed and dissolved due to the strong centrifugal force generated by rotation, and the centrifuged material and solution are collected at the designated position inside the centrifugal device 2.
[0046] Finally, according to the experimental or production requirements, the operator can press the start button 7 multiple times to perform multiple feeding and centrifugation operations. Before each feeding, the flow rate of the feeding pipe 32 can be adjusted by adjusting the knob 5 to ensure that the amount of solution added each time is consistent. In this way, not only can the material be fed multiple times with equal amounts, but also the effect of each centrifugal separation can be stable and reliable.
[0047] In summary, the beneficial effects of the utility model are as follows:
[0048] 1. Convenient operation: by pre-filling the feeding pipe 32 with an equal amount of solution, and adjusting the knob 5 to achieve multiple equal additions, the operation process is greatly simplified, and the tedious steps of repeatedly injecting toxic solutions such as trichloroethylene by the operator near the instrument for a long time are reduced.
[0049] 2. Ensure safety and health: the liquid adding operation of the adjusting knob 5 reduces the direct contact of the operator with harmful solutions, reduces the risk of occupational exposure, and ensures the safety and health of the operator.
[0050] 3. Improve work efficiency: equal multiple feeding and centrifugation operation makes the entire extraction process more efficient and fast, which is suitable for large-scale sample processing, and improves the overall efficiency of the laboratory or production line.
[0051] Further, the centrifugal device 2 includes a mixture bin 21, a material receiving bin 22, an upper inner rotating bearing 23, and a lower inner rotating bearing 24.
[0052] The material receiving bin 22 is wrapped outside the mixture bin 21, the upper end of the mixture bin 21, the upper end of the material receiving bin 22, and the lower end of the material collecting hopper 31 are jointly installed on the upper inner rotating bearing 23, and the lower end of the mixture bin 21 and the lower end of the material receiving bin 22 are jointly installed on the lower inner rotating bearing 24.
[0053] The upper end of the mixture bin 21 is a liquid receiving port, the liquid receiving port and the material collecting port are both installed inside the upper inner rotating bearing 23, and the liquid receiving port is in communication with the material collecting port.
[0054] The wall of the mixing bin 21 is provided with two centrifugal openings 210, and the two centrifugal openings 210 are located inside the receiving bin 22.
[0055] The upper end of the receiving bin 22 is provided with an upper mounting opening, and the lower end of the receiving bin 22 is provided with a lower mounting opening. The upper mounting opening is mounted outside the upper inner rotating bearing 23, and the lower mounting opening is mounted outside the lower inner rotating bearing 24. The inside of the lower inner rotating bearing 24 is provided for the driving end of the driving device 6 to pass through and be mounted, and the driving end of the driving device 6 is fixedly mounted at the lower end of the mixing bin 21.
[0056] As shown in Figure 2 The centrifugal device 2 of the high-efficiency centrifugal extraction instrument is designed uniquely, which is composed of a mixing bin 21, a receiving bin 22, an upper inner rotating bearing 23, and a lower inner rotating bearing 24, which work cooperatively to achieve high-efficiency centrifugal separation.
[0057] When working, the solution flows into the mixing bin 21 from the collecting opening of the collecting hopper 31 through the liquid receiving opening inside the upper inner rotating bearing 23. The mixing bin 21 is the main area where the material and the solution are mixed and subjected to centrifugal force. Due to the arrangement of the upper inner rotating bearing 23 and the lower inner rotating bearing 24, when the driving device 6 is started, the mixing bin 21 rotates alone.
[0058] With the acceleration of rotation, the solution and the asphalt mixture in the mixing bin 21 are fully mixed and dissolved due to the centrifugal force. The wall of the mixing bin 21 is provided with two centrifugal openings 210, and the two centrifugal openings 210 are located inside the receiving bin 22. Under the action of centrifugal force, the solution is thrown to the centrifugal openings 210 and falls into the receiving bin 22, while the mixture continues to be centrifuged in the mixing bin 21.
[0059] The receiving bin 22 is designed to receive the solution thrown from the centrifugal openings 210 of the mixing bin 21. Its upper end and lower end are respectively mounted outside the upper inner rotating bearing 23 and the lower inner rotating bearing 24 through the upper mounting opening and the lower mounting opening, which ensures the stability of the receiving bin 22 during rotation. At the same time, the inside of the lower inner rotating bearing 24 is provided for the driving end of the driving device 6 to pass through and be mounted, and the driving end is fixedly mounted at the lower end of the mixing bin 21, thereby achieving the driving of the mixing bin 21.
[0060] Further, the centrifugal device 2 further comprises a receiving pipe 25 and a recovery bin 26.
[0061] The receiving pipe 25 communicates the receiving bin 22 and the recovery bin 26, and the outer surface of the recovery bin 26 is provided with a scale layer.
[0062] As shown in Figure 3As shown, when the centrifugal device 2 starts to work, the material and solution are mixed in the mixing bin 21 and begin to mix and dissolve under the action of centrifugal force. The centrifuged solution is thrown to the centrifugal port 210 and falls into the receiving bin 22, while the mixed material continues to stay in the mixing bin 21 and is centrifuged because it does not pass through the centrifugal port 210. At this time, the solution can be guided into the recovery bin 26 through the receiving pipe 25. The receiving pipe 25 serves as a channel connecting the receiving bin 22 and the recovery bin 26, ensuring that the centrifuged solution can be smoothly transferred from the receiving bin 22 to the recovery bin 26.
[0063] The recovery bin 26 is designed to collect and store the solution flowing from the receiving bin 22. The scale layer provided on the outer surface of the recovery bin 26 provides an intuitive measurement means for the operator, enabling them to accurately understand the amount and changes of the material in the recovery bin 26. By reading the values on the scale layer, the operator can determine when the recovery bin 26 needs to be emptied or other processing is required.
[0064] Further, the driving device 6 includes a mounting seat 61 and a driving motor 62.
[0065] The mounting seat 61 is mounted inside the base 1, and the driving motor 62 is vertically mounted on the mounting seat 61, and the driving end of the driving motor 62 is connected with a rotating main shaft 63, which penetrates the inside of the lower inner rotating bearing 24 and is fixedly installed with the lower end of the mixing bin 21.
[0066] As shown, Figure 2 In the high-efficiency centrifugal extraction instrument, the driving device 6 plays a crucial role, which is responsible for providing power to drive the centrifugal device 2 to rotate. Specifically, the driving device 6 includes two parts: a mounting seat 61 and a driving motor 62.
[0067] The mounting seat 61 is firmly mounted inside the base 1, serving as a support structure for the driving motor 62. The driving motor 62 is vertically mounted on the mounting seat 61, and its design ensures the stability and efficiency of power transmission. The driving end of the driving motor 62 is connected with a rotating main shaft 63, which is a key component for driving the centrifugal device 2 to rotate.
[0068] The rotating main shaft 63 extends from the driving end of the driving motor 62, penetrates the inside of the lower inner rotating bearing 24, and is finally fixedly installed with the lower end of the mixing bin 21. Such a design enables the power generated by the driving motor 62 to be directly transmitted to the mixing bin 21 through the rotating main shaft 63 when the driving motor 62 is started, thereby driving it to rotate alone.
[0069] Throughout the centrifugal separation process, the stability and efficiency of the drive unit 6 are crucial to ensuring the separation effect. By precisely controlling the speed and rotation time of the drive motor 62, the operator can flexibly adjust the centrifugal separation parameters to suit the separation requirements of different materials and solutions.
[0070] To further explain, an observation port is provided on one side surface of the base 1 , and an observation door 8 is hingedly installed on the observation port. The observation door 8 is made of a transparent material.
[0071] like Figure 1 As shown, the transparent material of observation door 8 allows the operator to easily observe the state of the material or solution collected in recovery bin 26. After centrifugation is completed, the operator can directly view the separation results through observation door 8 and determine whether further processing or collection is required. This not only improves work efficiency but also reduces the risk of contamination caused by frequent opening of the equipment.
[0072] Furthermore, the design of the inspection door 8 allows the operator to quickly open it for maintenance when necessary. For example, when cleaning the centrifuge 2 or the liquid-filling device 3, the operator can easily open the inspection door 8 and directly access the required areas. This not only simplifies maintenance but also improves the reliability and service life of the equipment.
[0073] To further explain, movable handles 9 are respectively installed on the two side surfaces of the base 1.
[0074] like Figure 1 As shown, the installation of the mobile handle 9 allows the operator to easily grasp and move the entire high-efficiency centrifugal extractor. Whether adjusting the position within the laboratory or transferring it between different laboratories or production lines, the operator can easily move the device from one location to another by grasping the mobile handle 9. This not only improves work efficiency but also reduces the risk of damage caused by moving the device.
[0075] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific embodiments of the present invention without inventive effort, and such equivalent variations or substitutions are encompassed within the scope of the claims of this application.
