Technical Field

[0001] The invention relates to the technical field of automatic microparticle dialysis, and in particular to a fully automatic microparticle dialysis measuring device. Background Art

[0002] There are usually two ways to measure particle dialysis: spectroscopy and gravimetry.

[0003] The spectroscopy method uses the differences in the color spectrum of light reflected by particles of different contents to determine the content of particles, but the accuracy is often low.

[0044] Refer to the following Figure 1-Figure 15 A fully automatic microparticle dialysis assay device provided by the present invention is described.

[0045] Reference Figure 1-Figure 15 This embodiment first provides a fully automatic particle dialysis measurement device, which generally may include: a frame 100; a liquid tank 200, a collection tank 300, an annular spring 400, a cylinder 500 and a plurality of fastening components 600.

[0046] The liquid tank 200 is arranged on the frame 100 for receiving the filtered liquid, and a filter membrane 210 for filtering particles is arranged at the bottom of the liquid tank 200, and a first annular groove 220 is arranged on the outer wall of the liquid tank 200. The collecting tank 300 is arranged on the frame 100 and is located directly below the liquid tank 200, and a second annular groove 310 is arranged on the inner wall of the collecting tank 300. The first clamping groove 311 and the second clamping groove 312 are respectively arranged at both ends of the second annular groove 310. The annular spring piece 400 is arranged in the second annular groove 310, and the annular spring piece 400 protrudes to the outside of the liquid tank 200, and the protruding curvature of the annular spring piece 400 is consistent with the concave curvature of the second annular groove 310. The annular spring piece 400 is also provided with a first annular protrusion 410 and a second annular protrusion 420 at both ends, and the first annular protrusion 410 and the second annular protrusion 420 are respectively engaged in the first clamping groove 311 and the second clamping groove 312. The cylinder 500 is provided on the frame 100 and is located below the collection tank 300, and is used to push the collection tank 300 to move upward so that the collection tank 300 is docked with the liquid tank 200. A plurality of fastening components 600 are provided on the collection tank 300, and are used to squeeze the annular spring piece 400 after the collection tank 300 is docked with the liquid tank 200, so that the annular spring piece 400 is recessed toward the inside of the collection tank 300 and is engaged with the first annular groove 220.

[0047] The annular spring piece 400 is arranged in the second annular groove 310. After the liquid tank 200 and the collecting tank 300 are docked, the fastening assembly 600 presses the annular spring piece 400, so that the annular spring piece 400 changes from an initial state of protruding toward the second annular groove 310 to a state of being recessed toward the inside of the collecting tank 300. The annular spring piece 400 is clamped together with the first annular groove 220, thereby improving the sealing effect between the liquid tank 200 and the collecting tank 300.

[0048] The solution of this embodiment is to respectively set a first annular groove 220 and a second annular groove 310 on the liquid tank 200 and the collecting tank 300, and set an annular spring piece 400, and utilize the first annular protrusion 410 and the second annular protrusion 420 at both ends of the annular spring piece 400 to form a double-layer seal between the liquid tank 200 and the collecting tank 300, thereby greatly improving the sealing effect, thereby reducing the risk of air leakage and the detection cost during the detection process, and improving the detection accuracy.

[0049] A plurality of sealing grooves 320 are also provided on the inner wall surface of the collection tank 300. The plurality of sealing grooves 320 are located below the second annular groove 310 and are spaced apart along the annular direction of the second annular groove 310. The bottom portions of the plurality of sealing grooves 320 extend upward and communicate with the bottom of the second annular groove 310. The plurality of fastening assemblies 600 are disposed in the plurality of sealing grooves 320 in a one-to-one correspondence.

[0050] By digging a plurality of sealing grooves 320 on the inner wall surface of the collection tank 300, and extending the bottom of the sealing grooves 320 upward to communicate with the bottom of the second annular groove 310, a plurality of fastening components 600 are arranged in the plurality of sealing grooves 320 one by one, so that the fastening components 600 can press the annular spring sheet 400 through the bottom of the second annular groove 310, which not only ensures the smooth deformation of the annular spring sheet 400, but also has a delicate structure and will not affect the normal docking of the collection tank 300 and the liquid tank 200. In some preferred embodiments, the plurality of sealing grooves 320 are evenly distributed and spaced along the annular direction of the second annular groove 310, so that the annular spring sheet 400 is subjected to a more uniform force applied by the fastening components 600.

[0051] Reference Figure 10-11 The fastening assembly 600 may generally include: a limiting plate 610 , a first slider 620 , a second slider 630 and a spring 640 .

[0052] The limiting plate 610 is arranged at the notch of the sealing groove 320, and its surface close to the inside of the liquid tank 200 has a curvature, which is consistent with the curvature of the inner wall surface of the liquid tank 200. The first slider 620 is movably arranged in the sealing groove 320 along the vertical direction. The second slider 630 is arranged below the first slider 620, and the second slider 630 is configured to move along the radial direction of the collection tank 300. When the second slider 630 moves along the radial direction of the collection tank 300, it drives the first slider 620 to move along the vertical direction. The spring 640 is arranged above the first slider 620 and presses the first slider 620. After the liquid tank 200 is docked with the collection tank 300, the outer wall surface of the liquid tank 200 squeezes the second slider 630, so that the second slider 630 moves outward along the radial direction of the collection tank 300, thereby driving the first slider 620 to move upward, and then squeezing the annular spring sheet 400, so that the annular spring sheet 400 is recessed into the first annular groove 220.

[0053] The solution of this embodiment specifically sets the curvature of the surface of the limiting plate 610 close to the inside of the liquid tank 200 to be consistent with the curvature of the inner wall surface of the liquid tank 200, thereby ensuring smooth docking of the liquid tank 200 and the collection tank 300.

[0054] In some embodiments, the limiting plate 610 can be directly clamped in the notch of the sealing groove 320, wherein the limiting plate 610 and the notch of the sealing groove 320 can be interference fit. In other embodiments, the limiting plate 610 can be fixed to the notch of the sealing groove 320 by a connector, such as a stud or a screw.

[0055] Furthermore, in the solution of this embodiment, a spring 640 is provided above the first slider 620, so that when the liquid tank 200 and the collection tank 300 are unmated, the spring 640 can press the first slider 620 to reset the first slider 620. It is understood that in some embodiments, the spring 640 can be replaced by other elastic compression members having the characteristics of the spring 640.

[0056] In some preferred embodiments, the sealing groove 320 is configured such that the middle portion of the groove bottom thereof is recessed toward the outside of the collecting tank 300 , and extends upward to communicate with the groove bottom of the second annular groove 310 .

[0057] The solution of this embodiment is to set a second slider 630 that can move radially along the collecting tank 300. When the liquid tank 200 and the collecting tank 300 are docked, the outer wall of the liquid tank 200 squeezes the second slider 630, so that the second slider 630 moves radially outward, thereby squeezing the first slider 620 to move upward. The first slider 620 squeezes the annular spring piece 400, so that the annular spring piece 400 is recessed into the second annular groove 310, which not only improves the sealing between the liquid tank 200 and the collecting tank 300, but also has a sophisticated structure and is easy to install.

[0058] like Fig.11 As shown, a notch is formed at the bottom of the limiting plate 610, and the second slider 630 moves in the radial direction through the notch. A rib extends outward from the end surface of the second slider 630 near the bottom of the sealing groove 320, and the rib is engaged with the limiting plate 610 to prevent the second slider 630 from falling out of the sealing groove 320.

[0059] In some embodiments, a chamfer may be provided at the top end of the first slider 620 facing the second annular groove 310, so as to avoid the edges of the first slider 620 from wearing the annular spring piece 400 and enable the first slider 620 to squeeze the annular spring piece 400 more smoothly to deform it.

[0060] In some embodiments, the bottom end of the first slider 620 can be set to an inclined surface extending from the inside of the collection tank 300 to the outside from top to bottom, and the top of the second slider 630 close to the bottom of the sealing groove 320 can be formed with a chamfer, and the inclination angle of the chamfer is consistent with the inclined surface of the bottom end of the first slider 620 to improve the smoothness of movement of the first slider 620 and the second slider 630.

[0061] In some embodiments, a cover that can be opened or closed is provided on the top of the liquid tank 200 so that the liquid tank 200 can form a closed space during the detection process. It is understandable that the cover can be provided on the top of the liquid tank 200 or on the side wall of the liquid tank 200. In some embodiments, the cover and the liquid tank 200 can be threadedly connected. In other embodiments, the cover and the liquid tank 200 can be configured to be snap-fitted, and a sealing device, such as a sealing ring, can be provided between the cover and the liquid tank 200.

[0062] The annular spring piece 400 is made of metal.

[0063] The solution of this embodiment configures the annular spring piece 400 to be made of metal material and utilizes its metal properties (its own ultra-thin properties and excellent elasticity and hardness) to make the contact between the annular spring piece 400 and the second annular groove 310 closer, thereby improving the sealing effect.

[0064] In some embodiments, the annular spring piece 400 can be configured as steel, such as 304 steel. In other embodiments, the annular spring piece 400 can be made of copper. In some embodiments, the annular spring piece 400 can also be subjected to surface treatment such as gold plating or nickel plating to improve its corrosion resistance and appearance.

[0065] An annular arc-shaped protrusion 221 is disposed at the bottom of the first annular groove 220 , and the annular spring piece 400 contacts the arc-shaped protrusion 221 under the pressure of the fastening assembly 600 to form a “W” shape.

[0066] The solution of this embodiment is to set an annular arc-shaped protrusion 221 at the bottom of the first annular groove 220, so that when the annular spring piece 400 is recessed into the first annular groove 220 under the pressure of the fastening assembly 600, it will contact with the arc-shaped protrusion 221, and the arc-shaped protrusion 221 presses the annular spring piece 400, so that the contact between the annular spring piece 400 and the first annular groove 220 is closer.

[0067] Furthermore, the annular spring piece 400 forms a special "W" shape under the extrusion of the arc-shaped protrusion 221. The three arc-shaped inclined surfaces formed by the annular spring piece 400 under the extrusion of the arc-shaped protrusion 221 are closer to the first annular groove 220. Since the deformation direction of the annular spring piece 400 is oblique, the thrust is stronger and the sealing effect is better when it is subjected to air pressure, and the gas is less likely to pass through. The sealing effect between the liquid tank 200 and the collection tank 300 is greatly improved, thereby improving the measurement accuracy of the fully automatic particle dialysis measurement device. The annular spring piece 400 is affected by the arc-shaped protrusion 221, and its elastic force that has not been fully released will squeeze the first annular protrusion 410 and the second annular protrusion 420, so that the contact between the first annular protrusion 410, the second annular protrusion 420 and the first slot 311, the second slot 312 and the outer wall of the liquid tank 200 is closer, thereby further improving the sealing effect between the liquid tank 200 and the collection tank 300, and further improving the measurement accuracy of the fully automatic microparticle dialysis measurement device.

[0068] like Figure 12-15 As shown, a plurality of slits 430 are arranged at intervals on the annular spring sheet 400 , and the length of the plurality of slits 430 is smaller than the arc length of the arc-shaped protrusion 221 .

[0069] In the solution of this embodiment, a plurality of slits 430 are provided on the annular spring sheet 400, so that the annular spring sheet 400 can be smoothly deformed after being squeezed by the first slider 620, and changes from the initial state of being convex toward the second annular groove 310 to being concave toward the first annular protrusion 410. The length of the slit 430 is set to be smaller than the arc length of the arc protrusion 221, thereby ensuring that after the annular spring sheet 400 is deformed into a "W" shape, the two arc-shaped inclined surfaces at both ends can be tightly connected, thereby ensuring the sealing effect.

[0070] In some preferred embodiments, the plurality of slits 430 on the annular spring piece 400 are evenly distributed to further improve the smoothness of deformation of the annular spring piece 400 .

[0071] Grease (not shown in the figure) is provided on the arc-shaped protrusion 221 , and the grease moves toward the two ends of the first annular groove 220 under the pressure of the annular elastic sheet 400 .

[0072] The solution of this embodiment is to provide grease on the arc-shaped protrusion 221 so that the grease on the arc-shaped protrusion 221 is squeezed toward the two ends of the first annular groove 220 after contacting the annular spring piece 400, thereby further improving the airtightness between the arc-shaped inclined surfaces at the upper and lower ends of the annular spring piece 400 and the first annular groove 220, avoiding gas leakage through the slit 430, and improving the sealing effect between the liquid tank 200 and the collection tank 300, thereby improving the measurement accuracy of the fully automatic microparticle dialysis measurement device.

[0073] The surface of the second sliding block 630 close to the axial direction of the collecting tank 300 is an inclined surface 631 , and the inclined surface 631 extends from top to bottom in the axial direction of the collecting tank 300 .

[0074] The solution of this embodiment is to set the surface of the second slider 630 close to the axial direction of the collecting tank 300 as a slope 631 extending from top to bottom in the axial direction of the collecting tank 300, so that during the docking process of the liquid tank 200 and the collecting tank 300, the second slider 630 can be squeezed by the outer wall of the liquid tank 200 and move more smoothly in the radial direction, thereby reducing the docking resistance between the liquid tank 200 and the collecting tank 300.

[0075] A chamfer 230 is formed at the bottom end of the outer wall surface of the liquid tank 200 , and the inclination angle of the chamfer 230 is consistent with the inclination angle of the inclined surface 631 of the second sliding block 630 .

[0076] The solution of this embodiment sets the inclination angle of the chamfer 230 at the bottom end of the outer wall of the liquid tank 200 to be consistent with the inclination angle of the inclined surface 631 of the second slider 630, so that the chamfer 230 of the outer wall of the liquid tank 200 forms a surface contact with the second slider 630, while ensuring the smooth docking of the liquid tank 200 and the collection tank 300, and further improving the sealing effect between the liquid tank 200 and the collection tank 300, thereby improving the measurement accuracy of the full-automatic microparticle dialysis measurement device.

[0077] The fully automatic particle dialysis measuring device may also generally include an air inlet pipe 240 and a gas compressor.

[0078] The air inlet pipe 240 is disposed on the liquid tank 200. The gas compressor is connected to the air inlet pipe 240 and delivers gas to the liquid tank 200 through the air inlet pipe 240, so that the liquid in the liquid tank 200 penetrates into the collection tank 300.

[0079] In the solution of this embodiment, a gas compressor is arranged on the frame 100 so that the gas compressor, the liquid tank 200 and the collection tank 300 form an integrated structure, thereby reducing the difficulty of operation and improving the detection accuracy.

[0080] In some preferred embodiments, the air inlet pipe 240 may be disposed at the top of the liquid tank 200 to prevent the liquid from flowing back through the air inlet pipe 240 or remaining in the air inlet pipe 240 , thereby improving the detection accuracy.

[0081] A filter membrane 210 is also disposed on the top of the collection tank 300 .

[0082] In the solution of this embodiment, by setting a filter membrane 210 on the top of the collection tank 300, the liquid in the liquid tank 200 is filtered twice through two filter membranes 210, thereby improving the filtering accuracy of the liquid and further improving the detection accuracy.

[0083] In some embodiments, one or more filter membranes 210 may be further provided in the liquid tank 200 and the collection tank 300 to further improve the detection accuracy.

[0084] The fully automatic particle dialysis measuring device may generally further include: a mounting plate 110 , at least one sliding rod 120 , an upper plate 130 , a lower plate 140 and a base 150 .

[0085] The mounting plate 110 is disposed below the collection tank 300 to support the collection tank 300. At least one slide bar 120 is disposed on the frame 100. The upper plate 130 is disposed below the mounting plate 110 and is located above the cylinder 500. The upper plate 130 is sleeved on the slide bar 120 to support the mounting plate 110. The upper plate 130 is connected to the cylinder 500, and the upper plate 130 is configured to move up and down along the slide bar 120 under the action of the cylinder 500. The lower plate 140 is disposed below the cylinder 500 to support the cylinder 500. The base 150 is installed at the bottom of the frame 100 to support the lower plate 140.

[0086] In the solution of this embodiment, the cylinder 500 is arranged on the base 150 installed at the bottom of the frame 100, thereby improving the structural stability of the cylinder 500. The cylinder 500 is used to push the collection tank 300 to dock with the liquid tank 200, ensuring the stability of the collection tank 300 and the liquid tank 200 when docking.

[0087] Furthermore, the solution of this embodiment, by setting a slide rod 120, enables the upper plate 130 to move up and down along the slide rod 120 under the action of the cylinder 500, thereby ensuring the position accuracy of the collection tank 300 during the movement process and ensuring the smooth docking of the collection tank 300 and the liquid tank 200.

[0088] In some implementations, a plurality of slide bars 120 may be disposed on the frame 100 , and the plurality of slide bars 120 may be evenly distributed, thereby further improving the position accuracy and smoothness of the movement of the liquid tank 200 .

[0089] In some embodiments, at least one fixing rod 160 is further provided on the frame 100, and at least one fixing rod 160 is provided around the liquid tank 200 to fix the liquid tank 200 on the frame 100, so as to improve the structural stability of the liquid tank 200 during the test process. In some preferred embodiments, four fixing rods 160 may be provided around the liquid tank 200, and the four fixing rods 160 are evenly distributed. In some embodiments, the fixing rod 160 may be configured as a screw.

[0090] The fully automatic particle dialysis measuring device may also generally include: a drying device 700 and a control panel 800. The drying device 700 is disposed on the frame 100 and is used to dry the filter membrane 210. The control panel 800 is disposed on the frame 100 and is connected to the cylinder 500 and the gas compressor and is used to control the cylinder 500 and the gas compressor.

[0091] The solution of this embodiment simplifies the operation process and reduces the difficulty of operation by setting the drying device 700, the liquid tank 200, the collection tank 300 and the cylinder 500 as an integrated machine. By setting a control panel 800, the cylinder 500 and the gas compressor are controlled by the control panel 800, the difficulty of operation is reduced, and the interference factors in the detection process are reduced, thereby improving the detection accuracy.

[0092] In some embodiments, the rack 100 is also provided with a power supply for supplying power to various components.

[0093] In some embodiments, a switch is also provided on the rack 100 for starting and stopping the fully automatic particle dialysis measuring device.

[0094] The specific working process of a fully automatic microparticle dialysis measuring device provided by the present invention is described in combination with the above embodiments:

[0095] After the fully automatic microparticle dialysis measuring device is started through the control panel 800, the dialyzed liquid is poured into the liquid tank 200. After the liquid tank 200 is sealed, the cylinder 500 pushes the collection tank 300 to move upward, and the collection tank 300 and the liquid tank 200 begin to dock. In the process of docking the collection tank 300 and the liquid tank 200, the outer wall of the liquid tank 200 squeezes the second slider 630, so that the second slider 630 moves outward in the radial direction, thereby squeezing the first slider 620 to move upward in the vertical direction. The first slider 620 moves upward to the bottom position of the second annular groove 310, squeezing the annular spring sheet 400, so that the annular spring sheet 400 changes from a state of convex toward the second annular groove 310 to a state of concave toward the first annular groove 220. The annular spring sheet 400 is concave toward the first annular groove 220, and the arc-shaped protrusion 221 of the first annular groove 220 conflicts with the annular spring sheet 400, so that the annular spring sheet 400 forms a special "W" shape. The outward force exerted by the arc-shaped protrusion 221 on the annular spring piece 400 makes the contact between the annular spring piece 400 and the first annular groove 220 closer, and the first annular protrusion 410 and the second annular protrusion 420 at both ends of the annular spring piece 400 are respectively pressed more closely between the first clamping groove 311, the second clamping groove 312 and the outer wall surface of the liquid tank 200 in the vertical direction under the action of pressure. In addition, the grease disposed on the surface of the arc-shaped protrusion 221 will partially move along the arc of the arc-shaped protrusion 221 to the two ends of the first annular groove 220 during the contact and pressing process between the annular spring piece 400 and the arc-shaped protrusion 221, thereby improving the airtightness between the annular spring piece 400 and the first annular groove 220.

[0096] After the liquid in the liquid tank 200 is filtered through the filter membrane 210 on the liquid tank 200 and the collection tank 300, the particles remain on the filter membrane 210. The filter membrane 210 is removed and weighed, and then sent to the drying device 700 for drying. After drying, it is weighed again to obtain the particle data.

[0097] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0098] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
