Description

Technical Field

[0001] The utility model relates to the technical field of glue adding equipment, in particular to a circulating heating constant temperature bubble-free quantitative glue adding machine. Background Art

[0002] Medical separation gel is commonly used in biochemistry, immunology, serum and other clinical medical tests to obtain high-quality serum samples. Separation gel is a semi-solid inert gel composed of several compounds. The separation gel is made entirely of medical polymer materials, has good thixotropy and heat resistance, can avoid high-temperature decomposition and precipitation of small molecules, and can greatly reduce the risk of clogging the pipeline of the test instrument.

[0003] In the separation gel production process, after adding gel to the separation gel test tube, since there are bubbles in the gel, it is necessary to remove the bubbles in the gel by centrifuging the test tube, thus adding a lot of centrifugal debubble work. Centrifugal work involves a relatively dangerous and risky process, which is dangerous to a certain extent.

[0004] Therefore, we propose to design a circulating heating constant temperature bubble-free quantitative glue adding machine. Utility Model Content

By pouring the separation glue raw material into the space between the outer hopper and the inner hopper through the movable door on the top cover, due to the limited space between the two hoppers, the separation glue raw material is heated by the spiral heating wires on both sides at the same time and the temperature rises rapidly, thereby effectively improving the heating speed of the separation glue raw material.

Then the solenoid valve is closed and the electric push rod is started again to drive the piston to squeeze the extracted separation glue out of the one-way valve from the discharge nozzle, thereby ensuring the quality of the separation glue entering the quantitative valve.

[0011] As a preferred solution of the circulating heating constant temperature bubble-free quantitative glue adding machine described in the utility model, the extraction end of the glue circulation pump is correspondingly connected to the bottom of the double-layer heating hopper, and a glue circulation pipe is jointly arranged between the discharge end of the glue circulation pump and the circulating constant temperature tank. The separation glue is pumped into the circulating constant temperature tank through the glue circulation pump, so as to maintain the flow stability of the separation glue.

[0012] As a preferred solution of the circulating heating constant temperature bubble-free quantitative glue adding machine described in the utility model, the top end of the reflux pipe extends from the top of the double-layer heating hopper and is connected to the inside thereof, and the mouth of the reflux pipe extends into the inner hopper. Since the separation glue reflux itself has a certain temperature, it only needs to be put into the inner hopper to be quickly heated, and then enter the circulating constant temperature tank again for stirring to fully remove bubbles.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0023] See also Figure 1-3 The utility model provides a circulating heating constant temperature bubble-free quantitative glue adding machine, which comprises a double-layer heating hopper 1.

[0024] The double-layer heating hopper 1 comprises an outer hopper 101 and an inner hopper 102, both of which are embedded with spiral heating wires 103, and a fixing rod 104 is fixedly connected between the outer hopper 101 and the inner hopper 102. The bottoms of the outer hopper 101 and the inner hopper 102 are both provided with discharge ports 105, and the top of the outer hopper 101 is threadedly connected with a top cover 106. By pouring the separation glue raw material into between the outer hopper 101 and the inner hopper 102 through the movable door on the top cover 106, due to the limited space between the two hoppers, the separation glue raw material is simultaneously heated by the spiral heating wires 103 on both sides and quickly heated, thereby effectively improving the heating speed of the separation glue raw material.

[0025] A circulating constant temperature tank 2 is arranged on one side of the double-layer heating hopper 1, and a motor 201 is fixedly connected to the bottom center of the circulating constant temperature tank 2. The driving shaft of the motor 201 passes through the circulating constant temperature tank 2 and is provided with a stirring rod, which is convenient for stirring the separation gel raw material in the circulating constant temperature tank 2, and can fully maintain the fluidity of the separation gel raw material before quantitative extraction, and at the same time facilitate the removal of bubbles in the separation gel raw material during the circulation process.

[0026] A pressure pump 3 is arranged on the top of the circulating constant temperature tank 2 , a connecting pipe 4 is fixedly connected to the liquid outlet of the pressure pump 3 , and a debris removal mechanism 5 is arranged at the bottom of the connecting pipe 4 .

[0027] In this embodiment, the impurity removal mechanism 5 includes a syringe 501, a solenoid valve 505 is arranged between the syringe 501 and the connecting pipe 4, an electric push rod 502 is fixedly connected to the bottom of the syringe 501, the telescopic end of the electric push rod 502 passes through the syringe 501 and is fixedly connected to the piston 503, a discharge nozzle 504 is arranged on one side of the syringe 501, and a one-way valve is arranged near the end of the syringe 501. The staff can monitor the discharge of the separation glue at any time through the transparent connecting pipe 4. Once bubbles are found in the separation glue, after opening the solenoid valve 505, the electric push rod 502 can be used to drive the piston 503 to move, and the part of the separation glue with bubbles can be extracted, and then the solenoid valve 505 can be closed, and the electric push rod 502 can be started again to drive the piston 503 to squeeze the extracted separation glue out of the one-way valve from the discharge nozzle 504, thereby ensuring the quality of the separation glue entering the quantitative valve 6.

[0028] A metering valve 6 is fixedly connected to the end of the connecting pipe 4, and a test tube 7 is arranged at the bottom of the discharge end of the metering valve 6. A rubber circulation pump 8 is arranged between the bottom of the double-layer heating hopper 1 and the circulating constant temperature tank 2. The extraction end of the rubber circulation pump 8 is correspondingly connected to the bottom of the double-layer heating hopper 1, and a rubber pipe 9 is arranged between the discharge end of the rubber circulation pump 8 and the circulating constant temperature tank 2. The separation rubber is pumped into the circulating constant temperature tank 2 through the rubber circulation pump 8 to maintain the flow stability of the separation rubber.

[0029] A reflux pipe 10 is provided on the top of the circulating constant temperature tank 2, wherein the top end of the reflux pipe 10 extends from the top of the double-layer heating hopper 1 and is connected to the inside thereof, and the mouth of the reflux pipe 10 extends into the inner hopper 102. Since the separation gel reflux itself has a certain temperature, it only needs to be put into the inner hopper 102 for rapid heating, and then enter the circulating constant temperature tank 2 again for stirring to fully remove bubbles.

[0030] When in use, the electronic devices such as the spiral heating wire 103, the motor 201, the electric push rod 502, the solenoid valve 505, the quantitative valve 6 and the rubber conveying circulation pump 8 are connected to an external power source and started.

[0031] The separation gel raw material is poured into the space between the outer bucket 101 and the inner bucket 102 through the movable door on the top of the top cover 106, wherein the space where the spiral heating wire 103 is located is filled with heating medium such as oil. The spiral heating wire 103 in the outer bucket 101 and the inner bucket 102 heats the oil, and then heats the separation gel flowing therein, so that the separation gel is heated evenly and maintains fluidity.

[0032] Under the action of the rubber conveying circulation pump 8, the rubber in the double-layer heating hopper 1 is sucked into the rubber conveying circulation pump 8, and the heated separation rubber is conveyed to the circulating constant temperature tank 2 through the rubber conveying pipe 9.

[0033] Due to the pressure of the glue delivery, the separation glue is fully mixed in the constant temperature tank, so that the separation glue is heated more evenly, and flows back to the double-layer heating hopper 1 through the reflux pipe 10, and is heated and extruded in a cycle to completely remove the bubbles in the separation glue.

[0034] The pressure pump 3 is located above the circulating constant temperature tank 2 . When the separation gel is sufficiently and evenly heated, the pressure pump 3 starts to work, sucking the separation gel and sending it into the quantitative valve 6 and adding it into the test tube 7 .

[0035] The quantitative valve 6 mainly plays the role of measuring the amount of separation gel added. Since the viscosity of the separation gel decreases and the fluidity increases after heating, the gel added to the test tube 7 reaches a bubble-free state, thereby eliminating the need for complicated centrifugation work.

[0036] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
