Description

Technical Field

[0001] The invention relates to a drying device for centrifuge tubes, in particular to a drying device for press-capped centrifuge tubes in the technical field of drying equipment. Background Art

[0002] A centrifuge tube is a tubular sample container. Some centrifuge tubes also have sealing covers or pressure covers. The centrifuge tubes are cleaned after the experiment and then left to air dry naturally or dried in a dryer.

[0003] The specification of Chinese invention patent CN201921475103.8 discloses a "centrifuge tube rapid drying machine", which includes a cylinder, a fan is arranged in the cylinder, an air heating device is arranged above the fan; a top cover is arranged on the top of the cylinder, a plurality of air ducts are arranged on the top cover, and the air ducts are connected to the cylinder; a plurality of air holes are opened on the air duct. The centrifuge tube rapid drying machine with the above structure dries the centrifuge tube quickly by blowing hot air to dry it.

[0004] The existing centrifuge tubes take a long time to dry naturally. Therefore, in order to improve the drying efficiency of the centrifuge tubes, most of them are dried by hot air. Since the centrifuge tubes are tubular, the centrifuge tubes are directly placed in the drying equipment, and the hot air can only dry the outside of the centrifuge tubes, but it is difficult for the hot air to directly enter the centrifuge tubes. Therefore, it is difficult to dry the inside of the centrifuge tubes, which affects the drying effect and drying efficiency of the centrifuge tubes. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that, since the centrifuge tube is tubular, when the centrifuge tube is directly placed in the drying equipment, the hot air can only dry the outside of the centrifuge tube, but it is difficult for the hot air to directly enter the inside of the centrifuge tube. Therefore, it is difficult to dry the inside of the centrifuge tube, which affects the drying effect and drying efficiency of the centrifuge tube.

[0006] In order to solve the above problems, the present invention provides a drying device for a gland-type centrifuge tube, comprising a code plate table, the back of the code plate table is fixedly connected to an electric lifting rail, the top of the electric lifting rail is fixedly connected to a hot air bin, the movable end of the electric lifting rail is fixedly connected to a hanging frame, the hot air bin, the hanging frame and the code plate table are arranged correspondingly from top to bottom, and a centrifuge tube is placed on the top of the code plate table;

[0007] Sliding grooves are provided at both the front and rear ends of the suspension frame. The two sliding grooves are slidably connected by equidistantly arranged clamping rods. The gland end of the centrifuge tube corresponds to the clamping rod, and the same end of the clamping rod is fixedly connected by a spring. The four corners of the top of the suspension frame are fixedly connected with lifting modules, and a pressure beam is fixedly connected between the output ends of two adjacent lifting modules. The pressure beam corresponds vertically to the sliding groove, and the bottom of the pressure beam is in contact with the top of the spring.

[0008] In the above-mentioned drying device for gland-type centrifuge tubes, the clamping rod is evenly tightened by pulling the spring sheet, so that the clamping rod clamps the gland of the centrifuge tube and the centrifuge tube is hung up. Then, the hot air bin dries the hung centrifuge tube with hot air from top to bottom, making it easier for the hot air to directly enter the tube, thereby effectively improving the drying effect and drying efficiency of the centrifuge tube.

[0009] As a further improvement of the present application, the spring piece is arranged in a wave shape, the trough section of the spring piece is fixedly connected to the clamping rod, and the peak section of the spring piece is in contact with the pressure beam. The spring piece is made of spring steel material. The spring piece automatically contracts by elastic force, thereby driving the clamping rod to tighten evenly. Conversely, the pressure beam compresses the spring piece to achieve the expansion of the spring piece, thereby achieving the dispersed deployment of the clamping rod.

[0010] As a further improvement of the present application, both front and rear ends of the top of the coding platform are fixedly connected with movable rails, one end of the movable rail extends out of the coding platform, and the top of the movable rail is movably connected with a collecting box, and the collecting box is vertically corresponding to the hanging frame. After the centrifuge tube is lifted for hot air drying, the collecting box is pushed along the movable rail to the bottom of the hanging frame to facilitate catching the dried centrifuge tube.

[0011] As a further improvement of the present application, the upper surface of the stacking table is provided with equally spaced stacking grooves, and the bottom and both ends of the stacking grooves are provided with drainage holes. The centrifuge tubes are placed in the stacking grooves, which effectively improves the placement stability of the centrifuge tubes. The drainage holes drain the water scattered from the centrifuge tubes after cleaning.

[0012] As another improvement of the present application, the stacking groove is U-shaped, the width of the stacking groove corresponds to the outer ring diameter of the centrifuge tube, and the depth of the stacking groove is greater than the outer ring diameter of the centrifuge tube, so that the centrifuge tube can be placed in the stacking groove laterally and stably, and the pressure cover of the centrifuge tube is at the top of the stacking groove, which is convenient for the clamping rod to clamp the pressure cover of the centrifuge tube.

[0013] As another improved supplement of the present application, a hot air blower is fixedly connected to the middle of the hot air bin, a lower bin plate is fixedly connected to the bottom of the hot air bin, air outlet holes are evenly provided on the surface of the lower bin plate, the hot air blower heats the air to form hot air, and the air outlet holes on the lower bin plate are used to achieve uniform blowing of the hot air.

[0014] As another improvement supplement of the present application, the outside of the leftmost and rightmost clamping rods are fixedly connected with closing strips, and both ends of the lower bin plate are fixedly connected with sealing gaskets, and the sealing gaskets are vertically corresponding to the closing strips. During the process of the hanging frame rising and combining with the hot air bin, the sealing gaskets and the closing strips are squeezed and sealed, which effectively reduces the leakage of hot air from the sides and effectively improves the drying effect of the hot air on the centrifuge tubes.

[0015] As another improvement of the present application, the air outlet is arranged in a long strip shape, and the air outlet is perpendicularly crossed with the clamping rod, and an extension bag is fixedly connected to the outside of the air outlet. The long strip air outlet blows out linear hot air conveniently, and the extension bag guides the direction of the hot air.

[0016] As another improvement supplement of the present application, the bottom of the lower warehouse plate is movably connected with a swing frame, and both ends of the bottom of the extension bag are fixedly connected with swing shafts, which are rotatably connected to the swing frame. The swing shaft is utilized to drive the bottom of the extension bag to swing left and right, thereby repeatedly changing the wind direction of the hot air, making it easier for the hot air to enter the centrifuge tubes in different suspension states.

[0017] As another improved supplement of the present application, a swing module is fixedly connected to one end of the hot air bin, and the output end of the swing module is movably connected to the swing frame. The swing module pushes the swing frame to swing back and forth, which facilitates the electrical control operation of the device.

[0018] In summary, the present invention stacks the centrifuge tubes on the top of the encoding disk table, the hanging frame first descends to the top of the encoding disk table, the pressure caps of the centrifuge tubes extend between the equally spaced clamping and hanging rods, the lifting module drives the pressure beam to rise, releases the squeezing of the spring sheet, and the spring sheet pulls the clamping and hanging rods to tighten evenly, so that the clamping and hanging rods clamp the pressure caps of the centrifuge tubes, and the centrifuge tubes are hung between the clamping and hanging rods, which is convenient for the tube mouths of the centrifuge tubes to be concentrated upward, and then the hanging frame rises and combines with the hot air bin, and the hot air bin uses hot air from top to bottom to perform hot air drying on the hung centrifuge tubes, which is convenient for the hot air to directly enter the tubes, thereby effectively improving the drying effect and drying efficiency of the centrifuge tubes.

[0031] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0032] The first implementation method:

[0033] Figure 1-4The invention shows a drying device for capping centrifuge tubes, comprising a code disk platform 1, the back of the code disk platform 1 is fixedly connected with an electric lifting rail 101, the top of the electric lifting rail 101 is fixedly connected with a hot air bin 2, the movable end of the electric lifting rail 101 is fixedly connected with a hanging frame 3, the hot air bin 2, the hanging frame 3 and the code disk platform 1 are arranged correspondingly from top to bottom, and a centrifuge tube 4 is placed on the top of the code disk platform 1; sliding grooves 301 are provided at both the front and rear ends of the hanging frame 3, and the two sliding grooves 301 are slidably connected by equidistantly arranged clamping and hanging rods 302, the capping end of the centrifuge tube 4 corresponds to the clamping and hanging rod 302, and the same end of the clamping and hanging rod 302 is fixedly connected by a spring piece 303, and the hanging frame The four corners of the top of 3 are fixedly connected with lifting modules 304, and a pressure beam 305 is fixedly connected between the output ends of two adjacent lifting modules 304. The pressure beam 305 corresponds vertically to the sliding slot 301, and the bottom of the pressure beam 305 contacts the top of the spring piece 303. The spring piece 303 is arranged in a wave shape, and the trough section of the spring piece 303 is fixedly connected to the clamping and hanging rod 302, and the peak section of the spring piece 303 contacts the pressure beam 305. The spring piece 303 is made of spring steel material, and the spring piece 303 automatically shrinks due to elastic force, thereby driving the clamping and hanging rod 302 to be evenly tightened. On the contrary, the pressure beam 305 presses the spring piece 303 to achieve the relaxation of the spring piece 303, thereby achieving the dispersed expansion of the clamping and hanging rod 302;

[0034] The cleaned centrifuge tubes 4 are stacked on the code disk platform 1, and the electric lifting rail 101 first drives the hanging frame 3 to descend to the top of the code disk platform 1, and the gland of the centrifuge tube 4 extends into between the equally spaced clamping and hanging rods 302, and the lifting module 304 drives the pressure beam 305 to rise, releasing the squeezing of the spring piece 303, and the spring piece 303 pulls the clamping and hanging rod 302 to tighten evenly, so that the clamping and hanging rod 302 clamps the gland of the centrifuge tube 4, and the centrifuge tube 4 is hung between the clamping and hanging rods 302, so that the tube mouth of the centrifuge tube 4 is concentrated upward, and then the hanging frame 3 rises and combines with the hot air bin 2, and the hot air bin 2 uses hot air from top to bottom to dry the hung centrifuge tube 4, so that the hot air can directly enter the tube, thereby effectively improving the drying effect and drying efficiency of the centrifuge tube 4.

[0035] Figure 1 and 5 As shown, both front and rear ends of the top of the code disk table 1 are fixedly connected with a movable rail 102, one end of the movable rail 102 extends out of the code disk table 1, and the top of the movable rail 102 is movably connected with a collecting box 103, and the collecting box 103 is vertically corresponding to the hanging frame 3. After the centrifuge tube 4 is lifted up for hot air drying, the collecting box 103 is pushed into the bottom of the hanging frame 3 along the movable rail 102, so as to receive the dried centrifuge tube 4;

[0036] After the electric lifting rail 101 drives the hanging frame 3 to rise, the centrifuge tube 4 is clamped and suspended by the clamping rod 302, and the collecting box 103 is pushed to the bottom of the hanging frame 3 along the moving rail 102. After the centrifuge tube 4 is dried with hot air, the clamping rod 302 releases the pressure cover of the centrifuge tube 4, and the collecting box 103 catches the fallen centrifuge tube 4, which is convenient for the recovery of the centrifuge tube 4 and effectively avoids the mixing of the dried centrifuge tube 4 with the centrifuge tube 4 on the code plate table 1.

[0037] Figure 5-6 As shown, the upper surface of the stacking table 1 is provided with equally spaced stacking grooves 104, and the bottom and both ends of the stacking grooves 104 are provided with leaking holes 105. The centrifuge tube 4 is placed in the stacking groove 104, which effectively improves the placement stability of the centrifuge tube 4. The leaking holes 105 discharge the water scattered from the cleaned centrifuge tube 4. The stacking groove 104 is U-shaped, and the width of the stacking groove 104 corresponds to the outer ring diameter of the centrifuge tube 4. The depth of the stacking groove 104 is greater than the outer ring diameter of the centrifuge tube 4, so that the centrifuge tube 4 can be placed in the stacking groove 104 in a horizontal and stable manner. At the same time, the gland of the centrifuge tube 4 is at the top of the stacking groove 104, which is convenient for the clamping rod 302 to clamp the gland of the centrifuge tube 4.

[0038] When the centrifuge tubes 4 are stacked on the stacking table 1, the tube bodies of the centrifuge tubes 4 correspond to the stacking grooves 104, and the centrifuge tubes 4 just fit into the stacking grooves 104, but there is no space for placing the glands of the centrifuge tubes 4 in the stacking grooves 104, so the glands of the centrifuge tubes 4 can only extend out of the stacking grooves 104, thereby facilitating the clamping rods 302 to clamp the glands extending out of the stacking grooves 104.

[0039] The second implementation method:

[0040] Compared with the first embodiment, this embodiment mainly adds a hot air blower 201 and a lower compartment plate 202. The specific newly added structures are as follows, and the remaining structures are consistent with the first embodiment.

[0041] Figure 7-9As shown, a hot air blower 201 is fixedly connected to the middle of the hot air bin 2, a lower bin plate 202 is fixedly connected to the bottom of the hot air bin 2, and air outlet holes 203 are evenly opened on the surface of the lower bin plate 202. The hot air blower 201 heats the air to form hot air, and the air outlet holes 203 on the lower bin plate 202 are used to achieve uniform blowing of the hot air. The outside of the clamping rod 302 is fixedly connected to a closing strip 204, and both ends of the lower bin plate 202 are fixedly connected to a sealing gasket 205, and the sealing gasket 205 and the closing strip 204 are fixedly connected. Vertically corresponding, when the hanging frame 3 rises and combines with the hot air bin 2, the sealing pad 205 and the closing strip 204 are squeezed and sealed, which effectively reduces the leakage of hot air from the side and effectively improves the drying effect of the hot air on the centrifugal tube 4. The air outlet 203 is arranged in a long strip shape, and the air outlet 203 corresponds to the clamping rod 302 vertically and crosswise. The outside of the air outlet 203 is fixedly connected with an extension bag 206. The long strip air outlet 203 is easy to control the linear hot air when blowing, and the extension bag 206 guides the wind direction of the hot air;

[0042] The hot air blower 201 on the hot air bin 2 heats the air to form hot air, and the hot air is blown out through the air outlet holes 203 on the lower bin plate 202. The hot air blown out from the long strip air outlet holes 203 is in a sheet-like linear shape, which is convenient for the extension bag 206 to guide the wind direction of the hot air. The hot air is evenly blown toward the suspended centrifuge tube 4, and the hot air is blown into the tube from top to bottom, effectively improving the drying effect of the centrifuge tube 4.

[0043] Figure 1 , Figure 8 and Fig.10 As shown, the bottom of the lower bin plate 202 is movably connected with a swing frame 207, and both ends of the bottom of the extension bag 206 are fixedly connected with a swing shaft 208, and the swing shaft 208 is rotatably connected to the swing frame 207. The swing shaft 208 is used to drive the bottom of the extension bag 206 to swing left and right, thereby repeatedly changing the wind direction of the hot air, so that the hot air enters the centrifuge tube 4 in different suspension states. One end of the hot air bin 2 is fixedly connected with a swing module 209, and the output end of the swing module 209 is movably connected with the swing frame 207. The swing module 209 drives the swing frame 207 to swing back and forth, which is convenient for the electronic control operation of the device;

[0044] When the hot air passes through the air outlet 203 and is blown out from the extension bag 206, the swing module 209 drives the swing frame 207 to swing back and forth repeatedly, so that the swing frame 207 drives the bottom of the extension bag 206 to swing left and right, allowing the blown hot air to be tilted and blown into the centrifuge tubes 4 in different hanging states, effectively improving the drying effect inside the centrifuge tube 4.

[0045] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
