Description

Technical Field

[0001] This invention relates to the field of water sample testing technology, and in particular to a liquid separation device for water sample testing. Background Technology

[0002] Water sample testing refers to the work of testing the physicochemical properties and microorganisms contained in groundwater during water supply hydrogeological surveys. By testing water samples, the environmental quality of the sampling site can be examined, the suitability or suitability of the water quality can be studied, and the degree of pollution or contamination of the water can be investigated.

[0003] Mineral oil content detection is an important indicator for assessing water pollution. After sampling rivers, lakes, and groundwater, chemical reagents need to be added to multiple samples from the same batch to mix and react with the water sample in order to separate the organic phase from the aqueous phase, thereby detecting the organic phase. Traditional detection experiments involve manual mixing and separation by laboratory staff, which is inefficient.

[0004] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the Invention

[0005] The purpose of this invention is to provide a liquid separation device for water sample testing that can effectively solve the above-mentioned technical problems.

[0006] To achieve the objectives of this invention, the following technical solution is adopted:

[0007] A liquid separation device for water sample testing, comprising a housing;

[0008] A drive motor is fixedly installed at the bottom of the housing, and a drive rod is driven to the drive end of the drive motor. The drive rod is coaxially arranged with the housing.

[0009] A turntable rotatably connected to the housing is sleeved on the outer side of the drive rod, and a first drive assembly for driving the turntable to move intermittently is provided on the top of the drive rod;

[0010] The surface of the turntable is fixed with sleeves evenly distributed along its axial direction. Each sleeve is rotatably connected to a mixing sleeve, and a mixing tube that rotates synchronously is placed inside the mixing sleeve. The lower end of the mixing sleeve extends out of the bottom surface of the turntable, and a first gear is fixed on its outer side. A second gear is fixed on the drive rod and meshes with the first gear to drive the mixing sleeve to mix liquids.

[0011] Below the second gear is a reciprocating disk that is slidably connected to the drive rod. The reciprocating disk has two liquid dispensing positions that are symmetrically arranged about the center of the drive rod. A dispensing bottle is fixedly installed at each of the liquid dispensing positions. The bottom of the dispensing bottle is connected to an aqueous phase collection tank and an oil phase collection tank through a hose, and a density sensor is installed inside the dispensing bottle.

[0012] The drive motor drives the drive rod to rotate, which in turn drives the first drive assembly to work and drive the turntable to move intermittently so that different mixing tubes move to the liquid distribution position. During this process, the second gear rotates synchronously, which drives the first gear to drive the mixing sleeve to rotate for mixing. The reciprocating disc slides vertically along the drive rod, first moving the liquid distribution bottle upward to open the outlet of the mixing tube so that the mixed liquid enters the liquid distribution bottle, and then moving the liquid distribution bottle downward to reset. During the downward movement of the liquid distribution bottle, the liquid inside it completes the stratification. The density sensor detects the liquid density at the bottom of the liquid distribution bottle and transmits the signal to the electronic control unit inside the housing, so that the solenoid valve on the aqueous phase collection tank or the oil phase collection tank opens to collect the aqueous phase or the oil phase.

[0013] Preferably, the first driving component includes:

[0014] Rotating rod: fixed to the top end of the drive rod;

[0016] The drive rod drives the rotating rod to rotate, which in turn drives the rocker arm to rotate, thereby achieving the intermittent movement of the turntable.

[0017] Preferably, the rocker arm has a movement angle of 60 degrees.

[0018] Preferably, a supporting boss is fixed on the outer circumferential surface of the mixing sleeve, and a rotating groove is formed on the inner circumferential surface of the sleeve, which is rotatably connected to the supporting boss. The longitudinal sections of both the supporting boss and the rotating groove are set to a "T" shape.

[0019] Preferably, the inner circumferential surface of the mixing sleeve is evenly provided with slots, and the outer circumferential surface of the mixing tube is fixedly provided with a locking block that is slidably connected to the slots.

[0020] Preferably, the top of the mixing tube is threaded with a sealing cap, and its outlet is slidably connected with a sealing plug.

[0021] Preferably, a counterweight is fixedly provided at the bottom of the sealing plug, and a lifting member that cooperates with the counterweight is fixedly provided at the inlet of the dispensing bottle.

[0022] Preferably, the lower end of the drive rod has a stroke groove on its outer circumferential surface, and the lower end of the reciprocating disc is provided with a guide block that cooperates with the stroke groove to realize its reciprocating motion.

[0023] Preferably, the guide block includes:

[0024] End cap: It is fixedly connected to the lower end cylinder of the reciprocating disc, and a telescopic rod is fixedly installed in its middle;

[0025] Guide head: One end slides in contact with the travel groove, and the other end slides inside the end cover and is fixedly connected to the telescopic rod.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] In this invention, the drive rod is driven by a drive motor. During the operation of the drive rod, on the one hand, it can drive the first gear to rotate and drive the second gear to rotate for mixing; on the other hand, it can simultaneously drive the rotating rod to rotate the rocker arm to move different mixing tubes to the dispensing position; at the same time, it can also simultaneously drive the reciprocating disc to drive the dispensing bottle to reciprocate for dispensing. This makes the device multifunctional, highly automated, and energy-efficient. Attached Figure Description

[0048] The following is a clear and complete description of a liquid separation device for water sample testing according to the present invention, with reference to the accompanying drawings.

[0049] like Figures 1 to 6 As shown, the present invention provides a liquid separation device for water sample testing, which includes a housing 1, a drive motor 2, a turntable 3, a first drive assembly 4, a mixing sleeve 5, a mixing tube 6, a reciprocating disc 7, a separating bottle 8, an aqueous phase collection tank 9, an oil phase collection tank 10, and an electrical control unit, etc.

[0050] Among them, such as Figure 4 As shown, the upper end of the inner circumferential surface of the housing 1 has a first annular flange 101 that receives the turntable 3; at the same time, a second annular flange 102 that receives the reciprocating disk 7 is also provided on the inner circumferential surface of the housing 1.

[0051] Both the drive motor 2 and the electronic control unit are fixed to the bottom of the housing 1, and the drive motor 2 is connected to the electronic control unit for control purposes. This is prior art and will not be described in detail here. The drive end of the drive motor 2 is connected to a drive rod 11, and the drive rod 11 is vertically arranged coaxially with the housing 1.

[0052] like Figures 1 to 3 As shown, the turntable 3 is sleeved on the outside of the drive rod 11. It is configured as a hexagonal turntable 3, and its outer circumferential surface is rotatably connected to the inner circumferential surface of the housing 1 through a supporting frustum. The first driving member is disposed on the top of the drive rod 11 and is used to drive the turntable 3 to move intermittently.

[0053] The surface of the turntable 3 is welded and fixed with sleeves 12 evenly distributed along its axial direction. Each sleeve 12 is rotatably connected to a mixing sleeve 5, and a mixing tube 6 that rotates synchronously is placed inside the mixing sleeve 5. The lower end of the mixing sleeve 5 extends out of the bottom surface of the turntable 3, and a first gear 13 is fixed on its outer side. A second gear 14 is fixed on the drive rod 11 by a key and meshes with the first gear 13 to drive the mixing sleeve 5 to mix liquids.

[0054] Below the second gear 14 is a reciprocating disk 7 slidably connected to the drive rod 11. The reciprocating disk 7 has two liquid distribution positions symmetrically arranged about the center of the drive rod 11. A liquid distribution bottle 8 is fixedly installed at each liquid distribution position via a flange. The bottom of each liquid distribution bottle 8 is connected to an aqueous phase collection tank 9 and an oil phase collection tank 10 via hoses 15. A solenoid valve is installed at the outlet pipe of the liquid distribution bottle 8, and the solenoid valve is controlled and connected to the electronic control unit. Furthermore, a density sensor is installed inside the liquid distribution bottle 8; the density sensor is controlled and connected to the electronic control unit to detect the liquid density at the bottom of the liquid distribution bottle 8, and sends a signal to the electronic control unit to control the opening and closing of the solenoid valve corresponding to the aqueous phase collection tank 9 or the oil phase collection tank 10. It should be noted that both the aqueous phase collection tank 9 and the oil phase collection tank 10 are provided with outlet pipes (not shown) to facilitate liquid discharge; furthermore, the working principle and installation method of the density sensor are existing technologies and will not be described in detail.

[0055] When this device is in operation, the drive motor 2 drives the drive rod 11 to rotate. On one hand, this drives the first drive assembly 4 to work and drive the turntable 3 to move intermittently so that different mixing tubes 6 can move to the liquid distribution position. On the other hand, it drives the second gear 14 to rotate synchronously, driving the first gear 13 to drive the mixing sleeve 5 to rotate for mixing. At the same time, it drives the reciprocating disc 7 to slide vertically along the drive rod 11, first moving the liquid distribution bottle 8 upward to open the outlet of the mixing tube 6 so that the mixed liquid enters the liquid distribution bottle 8, and then moving the liquid distribution bottle 8 downward to reset. During the downward movement of the liquid distribution bottle 8, the liquid inside it completes the stratification. The density sensor detects the liquid density at the bottom of the liquid distribution bottle 8 and transmits the signal to the control unit inside the housing 1, so that the solenoid valve corresponding to the aqueous phase collection tank 9 or the oil phase collection tank 10 is opened to collect the aqueous phase or oil phase. The device of this invention realizes automated mixing and liquid distribution, with more diversified functions and high efficiency. At the same time, the orderly operation of mixing and liquid distribution can be completed by a single motor drive, which is energy-saving and environmentally friendly.

[0056] It should be noted that the rotational speed of the drive rod 11, the number of teeth of the first gear 13 and the second gear 14, and the movement distance of the reciprocating disk 7 can be calculated and set as needed. This is existing technology and will not be elaborated further.

[0057] Specifically, in this embodiment, such as Figure 1 As shown, the first drive assembly 4 is configured as a crank-rocker 402 structure, which includes a rotating rod 401 and a rocker 402; one end of the rotating rod 401 is mounted on the top of the drive rod 11 and rotates synchronously with it.

[0058] One end of the rocker arm 402 is rotatably connected to the free end of the rotating rod 401, and a travel groove 403 that rotates with it is fixedly installed at the end of the rocker arm 402 to guide its movement and improve stability; at the end of the travel groove 403 away from the rocker arm 402, a support guide 404 is rotatably connected inside the groove, and the support guide 404 is rotatably connected to the support base 16 fixed on the surface of the housing 1 to provide guiding support for the travel groove 403.

[0059] The other end of the rocker arm 402 has a U-shaped through groove, which is adapted to the outer circumferential surface of the sleeve 12; the movement angle of the rocker arm 402 is 60 degrees.

[0060] By setting the drive rod 11 to drive the rotating rod 401 to rotate, which in turn drives the rocker arm 402 to rotate, thereby driving different sleeves 12 to rotate, thus realizing the intermittent motion of the turntable 3.

[0061] Specifically, in this embodiment, such as Figure 5 As shown, the outer circumferential surface of the mixing sleeve 5 has an integrally formed support boss, and the inner circumferential surface of the sleeve 12 has a rotating groove that is rotatably connected to the support boss. The longitudinal sections of both the support boss and the rotating groove are set to a "T" shape.

[0062] The inner circumferential surface of the mixing sleeve 5 is evenly provided with slots, and the outer circumferential surface of the mixing pipe 6 is fixed with a block that is slidably connected to the slots.

[0063] By setting the support boss to cooperate with the rotating groove and the locking block to cooperate with the locking groove, the stability of the mixing process is improved.

[0064] Specifically, in this embodiment, such as Figure 5 As shown, a sealing cap 601 is threadedly connected to the top of the mixing tube 6, and a sealing plug 602 is slidably connected to its outlet. The sealing plug 602 can be spherical or mushroom-shaped, etc. A counterweight 603 is installed at the bottom of the sealing plug 602, and a lifting component that cooperates with the counterweight 603 is installed at the inlet of the dispensing bottle 8. 18

[0065] The lifting component moves upward under the drive of the dispensing bottle 8, lifting the counterweight 603 and driving the sealing plug 602 to slide to open the mixing tube 6, so that the liquid in the dispensing bottle 8 flows into the dispensing bottle 8; then the dispensing bottle 8 is reset, and the counterweight 603 drives the sealing plug 602 to reset and close the outlet of the mixing tube 6 by its own weight.

[0066] In this invention, the drive rod 11 is driven by the drive motor 2. During operation, the drive rod 11 can, on the one hand, drive the first gear 13 to drive the second gear 14 to rotate for mixing; on the other hand, it can...

[0067] Furthermore, in this embodiment, a stroke groove 1101 is provided on the outer circumferential surface of the lower end of the drive rod 11, and a guide block 17 is provided on the lower end cylinder of the reciprocating disk 7 to cooperate with the stroke groove 1101 to realize its reciprocating motion; the rotation of the drive rod 11 drives the guide block 17 to slide along the stroke groove 1101, thereby driving the reciprocating disk 7 to perform reciprocating motion.

[0068] In this invention, the drive rod 11 is driven by the drive motor 2. During the operation of the drive rod 11, on the one hand, it can drive the first gear 13 to drive the second gear 14 to rotate for mixing; on the other hand, it can synchronously drive the rotating rod 401 to drive the rocker arm 402 to rotate and move the different mixing tubes 6 to the liquid distribution position; at the same time, it can also synchronously drive the reciprocating disc 7 to drive the dispensing bottle 8 to reciprocate for liquid distribution. This makes the device versatile, highly automated, and energy-efficient.

[0069] In another embodiment of the invention, such as Figure 6 As shown, the guide block 17 includes an end cap 1701 and a guide head 1702; the end cap 1701 is installed on the lower end cylinder of the reciprocating disk 7, and a telescopic rod 1703 is installed in the middle of it. The telescopic rod 1703 is an electric telescopic rod 1703, which is controlled and connected to the electronic control unit.

[0070] One end of the guide head 1702 is in sliding contact with the travel groove 1101, and the other end is slidably connected inside the end cover 1701 and fixedly connected to the telescopic rod 1703.

[0071] When the sample solution requires a longer reaction time or only centrifugation is needed, the telescopic rod 1703 can be opened to disengage the guide head 1702 from the travel tank 1101, allowing only mixing or centrifugation to be performed. After a period of time, the telescopic rod 1703 can be activated again to allow the guide head 1702 to slide into contact with the travel tank 1101 for liquid separation.

[0072] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
