The instrument is controlled by a microcomputer, and can automatically complete liquid injection, titration, stirring and end point determination. The measurement cycle is about 4-7 minutes, and the result is displayed on a liquid crystal screen and can be printed out.

The neutralization titration method is used, and the microcomputer is used to control the automatic completion of liquid addition, titration, stirring and determination of titration end point at room temperature. The measurement result is displayed on a liquid crystal screen and can be printed out.

[0003] After detection is completed, the pipes and mixing beakers of the equipment need to be cleaned. The conventional technical method needs to rely on anhydrous ethanol flushing. In this process, the used parts on the equipment need to be replaced, and the equipment can be used only after new parts are replaced. When the parts are taken out for cleaning, the equipment needs to be opened, which is easy to cause dust to enter and affect the detection result. SUMMARY

The present application has a novel structure, four groups of detection components and four groups of detection cups are synchronously rotated and replaced, the used detection components enter the soaking box, and after being connected with the upper anhydrous ethanol storage box, the pipes and parts are cleaned and soaked, the residual detection liquid is cleaned, and the equipment can be continuously used without being taken out, so that the use efficiency of the equipment is improved, and the opening of the box door is avoided to prevent dust from entering.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic acid value analyzer, comprising a detection chamber, a door rotatably mounted on the bottom front of the detection chamber, a placement platform fixed inside the detection chamber, and a turntable rotatably mounted on the placement platform. Four detection cups are placed on the turntable via placement slots. An immersion tank is fixed to the rear end of the placement platform. A detection assembly is provided between the immersion tank and the turntable. The detection assembly includes a circular plate, which is rotatably mounted on the placement platform via a shaft. Four sets of connecting ends are equidistantly arranged at the bottom of the circular plate. An injection head assembly is fixed to the bottom of each connecting end, and a flexible tube is fixed to the top of each connecting end. The outer sleeve is provided and wraps around the top of the test cup. The two sets of the detection components are symmetrically perpendicular to the immersion tank and the test cup, respectively. A detection liquid delivery device is fixed at the top of the test tank, directly opposite the test cup. Two connecting pipes are fixed at the upper end of the corresponding hose of the detection liquid delivery device. An anhydrous ethanol storage tank is fixed at the rear end of the test tank, directly opposite the immersion tank. A corrugated pipe is fixed at the position of the anhydrous ethanol storage tank corresponding to the position of the following set of hoses. The connecting pipes and the corrugated pipe are connected to the two sets of symmetrical hoses. A stir bar is provided inside the sleeve. A magnetic generator is provided inside the placement platform, corresponding to the position of the test cup and the stir bar. Slots are opened on both sides of the rear end of the placement platform.

[0006] Furthermore, a drive motor is fixed to the bottom of the placement platform, a transmission belt is mounted on the output end surface of the drive motor, the pulley at the other end of the transmission belt is fixedly connected to the shaft of the circular plate, and the top of the output end of the drive motor is fixedly connected to the turntable.

[0007] Furthermore, the detection assembly also includes insert rods. Four insert rods are equidistantly slidably inserted into the surface of the circular plate, and a first spring is sleeved on the surface of the insert rods. The bottom of the first spring is fixedly connected to the circular plate. A ring is fixed to the bottom of the insert rod through the circular plate. Sliding rods are fixed to both sides of the top of the sleeve, and the top of the sliding rods is fixedly connected to the ring.

[0008] Furthermore, the two sides of the connecting end are slidably sleeved on the slide rod, and a second spring is sleeved on the surface of the slide rod. The top and bottom of the second spring are fixedly connected to the connecting end and the sleeve, respectively. Vertical plates are slidably inserted into both sides of the sleeve. The top of the vertical plate is rotatably connected to a connecting rod through a rotating shaft, and the other end of the connecting rod is rotatably connected to the connecting end through a rotating shaft.

[0009] Furthermore, the sleeve has a horizontal groove corresponding to the position of the vertical plate, and the vertical plate slides horizontally along the groove. The bottom of the vertical plate is fixed with a post, and the two ends of the stir bar have insertion holes, with the post inserted into the insertion holes.

[0010] Furthermore, a fixing plate is fixed to the top of the ring, a limiting sleeve is slidably sleeved on the surface of the hose, and a third spring is fixed between the limiting sleeve and the fixing plate.

[0011] Furthermore, a first electric push rod is fixed to the bottom of the detection liquid delivery device, and the extended end of the first electric push rod passes through the circular hole of the ring and presses against the top of the connecting end.

[0012] Furthermore, a connecting frame is fixed to the bottom of the corrugated pipe, and electromagnetic clamps are provided inside the connecting frame and outside the connecting pipe of the detection liquid delivery device. The hose is fixed to the corrugated pipe and the connecting pipe by the electromagnetic clamps.

[0013] Furthermore, a second electric push rod is fixed to the bottom of the anhydrous ethanol storage tank, and the extended end of the second electric push rod is fixedly connected to the connecting frame. A third electric push rod is fixed to the bottom of the connecting frame, and the extended end of the third electric push rod is in contact with the connecting end at the top of the soaking tank.

[0014] Furthermore, a fourth electric push rod is fixed on the side of the anhydrous ethanol storage tank at the position of the insertion rod at the top of the soaking tank, and the extended end of the fourth electric push rod is in contact with the top of the insertion rod.

[0015] The beneficial effects of this invention are:

[0016] This invention uses a drive motor to rotate a turntable, and a transmission belt also drives the turntable to rotate. The four sets of detection cups and four sets of detection components rotate synchronously and can be used interchangeably to avoid contamination and also to avoid dust entering due to frequent opening of the box door.

[0017] The detection component of this invention is inserted into a circular plate via a rod and a first spring, rotating with the turntable and used interchangeably with the detection cup. When the detection component located at the top of the detection cup moves downward at the connecting end, the flexible tube changes from a curved shape to a straight shape, and the limiting sleeve and the third spring retract and move. Through the connection of the connecting rod and the vertical plate, the vertical plate moves laterally along the slide groove. At this time, the insertion post of the vertical plate leaves the insertion hole of the stirrer. It should be noted that when the stirrer first contacts the bottom of the detection cup, the detection end has not yet moved to the lowest point. Therefore, subsequent movement is simply achieved by the connecting rod pushing the vertical plate laterally to separate it from the stirrer. The stirrer can cooperate with the magnetic generator inside the placement platform to stir and mix. This technology is existing technology. At the same time, during the stirring process, the sleeve wraps around the top of the detection cup, preventing liquid splashing. Subsequently, under the elastic force of the second spring, the detection end slides upward along the slide rod, and the insertion post of the vertical plate re-inserts into both ends of the stirrer, bringing it out of the detection cup for unified cleaning. Because the bottom of the sleeve is flush with the top of the detection cup, there is no rotational interference.

[0018] This invention uses a fourth electric push rod to press the insertion rod, causing the entire detection assembly to move downwards. The sleeve part is first inserted into the soaking tank for soaking and cleaning. Then, the connecting end is cleaned reciprocally by the third electric push rod. The injection head assembly can also enter the soaking tank. In conjunction with the anhydrous ethanol storage tank, the tubing is rinsed to clean the residual reagent inside the detection assembly. During the subsequent rotation, the suspension effect can be used to dry it. At the same time, the dripping solution is recovered through the trough at the end of the placement platform.

[0019] This invention uses a second electric push rod to move the connecting frame downwards, causing the corrugated pipe to unfold until it connects with the top of the hose. Then, the hose is clamped by electromagnetic clamps on both sides of the connecting pipe and inside the connecting frame, maintaining the connection between the hose and the connecting pipe and the corrugated pipe respectively. The first electric push rod presses the detection end at the top of the detection cup. Because a rubber ring is provided at the top edge of the detection cup, the sleeve will not move downwards. At this time, the detection end moves downwards along the slide rod, inserting the injection head assembly into the detection cup. At the same time, the stir bar is added to stir and mix the solution while adding the detection liquid, and the acid value is measured by the sensor.

[0020] Compared with the prior art, the present invention features four sets of detection components and four sets of detection cups that rotate synchronously and can be used interchangeably. After use, the detection components enter the soaking tank and are connected to the anhydrous ethanol storage tank at the top. The pipes and components are then cleaned and soaked to remove any residual detection liquid. The components can be used continuously without being removed, thereby improving the efficiency of the equipment and avoiding the entry of dust due to frequent opening of the tank door.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] Please see Figures 1 to 9This invention provides a technical solution: a fully automatic acid value analyzer, comprising a detection chamber 1, a door 11 rotatably mounted on the bottom front of the detection chamber 1, a placement platform 12 fixed inside the detection chamber 1, and a turntable 13 rotatably mounted on the placement platform 12. Four test cups 15 are placed on the turntable 13 through placement slots. An immersion tank 22 is fixed to the rear end of the placement platform 12. A detection component 3 is provided between the immersion tank 22 and the turntable 13. The detection component 3 includes a circular plate 31, which... The shaft is rotatably mounted on the placement platform 12, and four sets of connecting ends 35 are equidistantly arranged at the bottom of the circular plate 31. An injection head assembly 311 is fixed to the bottom of each connecting end 35, and a flexible tube 37 is fixed to the top of each connecting end 35. A sleeve 36 is provided around the bottom of each connecting end 35, and the sleeve 36 wraps around the top of the detection cup 15. Two symmetrical sets of the detection assembly 3 are perpendicularly aligned with the immersion tank 22 and the detection cup 15, respectively. A detection liquid delivery device 2 is fixed to the top of the detection tank 1, directly opposite the detection cup 15. Two connecting pipes 24 are fixed to the upper end of the corresponding hose 37 of the liquid delivery device 2. An anhydrous ethanol storage tank 21 is fixed at the rear end of the detection box 1, directly opposite the soaking tank 22. A corrugated pipe 26 is fixed to the anhydrous ethanol storage tank 21 at the position corresponding to the rear set of hoses 37. The connecting pipes 24 and the corrugated pipe 26 are connected to the two symmetrical sets of hoses 37. A stir bar 310 is provided inside the sleeve 36. A magnetic generator is provided inside the placement platform 12 at the position corresponding to the detection cup 15 and the stir bar 310. The two sides of the tail end of the device are provided with a trough 17. When using the device, the test substance is added into the test cup 15, and then the box door 11 is opened to place the four test cups 15 on the turntable 13. The box door 11 is closed, and the four test components 3 correspond one-to-one with the four test cups 15. After the frontmost and rearmost test components 3 are aligned with the test liquid delivery device 2 and the anhydrous ethanol storage tank 21, the test liquid is injected into the test cup 15 respectively, and the acid value is detected after stirring and mixing. The rearmost test components 3 are immersed in the immersion tank 22 to clean the test components 3.

[0033] In this embodiment, a drive motor 14 is fixed to the bottom of the placement platform 12. A transmission belt 18 is installed on the output end surface of the drive motor 14. The pulley at the other end of the transmission belt 18 is fixedly connected to the shaft of the circular plate 31. The top of the output end of the drive motor 14 is fixedly connected to the turntable 13. The drive motor 14 drives the turntable 13 to rotate, and the transmission belt 18 also drives the disc to rotate. The four sets of detection cups 15 and the four sets of detection components 3 rotate synchronously and are used interchangeably to avoid contamination and also to avoid dust entering due to frequent opening of the box door 11.

[0034] In this embodiment, the detection component 3 further includes insertion rods 32. Four insertion rods 32 are equidistantly slidably inserted into the surface of the circular plate 31, and a first spring 33 is sleeved on the surface of the insertion rods 32. The bottom of the first spring 33 is fixedly connected to the circular plate 31. A ring 34 is fixedly attached to the bottom of the insertion rods 32 through the circular plate 31. Sliding rods 312 are fixed on both sides of the top of the sleeve 36, and the top of the sliding rods 312 is fixedly connected to the ring 34. The two sides of the connecting end 35 are slidably sleeved on the sliding rods 312. A second spring 313 is sleeved on the surface of the sliding rods 312, and the top and bottom of the second spring 313 are fixedly connected to the connecting end 35 and the sleeve 36, respectively. Next, vertical plates 315 are slidably inserted into both sides of the sleeve 36. The top of the vertical plates 315 is rotatably connected to a connecting rod 314 via a rotating shaft, and the other end of the connecting rod 314 is rotatably connected to the connecting end 35 via a rotating shaft. The sleeve 36 has a transverse groove 38 corresponding to the position of the vertical plates 315, and the vertical plates 315 slide laterally along the groove 38. A post 39 is fixed to the bottom of the vertical plates 315. The stirrer 310 has insertion holes at both ends, and the post 39 is inserted into the insertion holes. A fixing plate 316 is fixed to the top of the ring 34. A limiting sleeve 318 is slidably fitted onto the surface of the hose 37. The limiting sleeve 318 and the fixing plate 316 are connected. A third spring 317 is fixed between them. The detection component 3 is inserted into the circular plate 31 via the insertion rod 32 and the first spring 33. It rotates together with the turntable 13 and is used interchangeably with the detection cup 15. When the detection component 3 located at the top of the detection cup 15 moves downward at the connecting end 35, the flexible tube 37 changes from a curved shape to a straight shape. The limiting sleeve 318 and the third spring 317 retract and move. Through the connection of the connecting rod 314 and the vertical plate 315, the vertical plate 315 moves laterally along the slide groove 38. At this time, the insertion post 39 of the vertical plate 315 leaves the insertion hole of the stirrer 310. It should be noted that when the stirrer 310 first contacts the bottom of the detection cup 15, the detection end has not yet moved to the lowest point. Therefore, subsequent movement is simply achieved by the connecting rod 314 pushing the vertical plate 315 to move laterally and separate it from the stirrer 310. The stirrer 310 can work with the magnetic generator inside the placement platform 12 to stir and mix. This technology is existing. At the same time, during the stirring process, the sleeve 36 wraps around the top of the detection cup 15, preventing liquid splashing. Then, under the elastic force of the second spring 313, the detection end slides upward along the slide rod 312, and the insert 39 of the vertical plate 315 re-inserts into both ends of the stirrer 310, bringing it out of the detection cup 15 and sending it out for cleaning. Because the bottom of the sleeve 36 is flush with the top of the detection cup 15, there is no rotational interference.

[0035] In this embodiment, a first electric push rod 25 is fixed to the bottom of the detection liquid delivery device 2. The extended end of the first electric push rod 25 passes through the circular hole of the ring 34 and presses against the top of the connecting end 35. A connecting frame 27 is fixed to the bottom of the corrugated pipe 26, and electromagnetic clamps 23 are provided inside the connecting frame 27 and outside the connecting pipe 24 of the detection liquid delivery device 2. The hose 37 is fixed to the corrugated pipe 26 and the connecting pipe 24 by the electromagnetic clamps 23. A second electric push rod 28 is fixed to the bottom of the anhydrous ethanol storage tank 21, and the extended end of the second electric push rod 28 is fixedly connected to the connecting frame 27. A third electric push rod is fixed to the bottom of the connecting frame 27. Push rod 29, and the extended end of the third electric push rod 29 is in contact with the connecting end 35 at the top of the soaking tank 22. The side of the anhydrous ethanol storage tank 21 is fixed with a fourth electric push rod 210 corresponding to the position of the insertion rod 32 at the top of the soaking tank 22, and the extended end of the fourth electric push rod 210 is in contact with the top of the insertion rod 32. The two sets of detection components 3 corresponding to the detection cup 15 and the soaking tank 22 have hoses 37 at their tops corresponding to the connecting pipe 24 and the corrugated pipe 26, respectively. Because the corrugated pipe 26 of the anhydrous ethanol storage tank 21 is far away, the connecting frame 27 is moved downward by the second electric push rod 28, and the corrugated pipe 26 unfolds until it is in contact with the top of the hose 37. The connection is made, and then the flexible tube 37 is clamped by the electromagnetic clamps 23 on both sides of the connecting tube 24 and inside the connecting frame 27, keeping the flexible tube 37 connected to the connecting tube 24 and the bellows 26 respectively. The detection liquid delivery device 2 is the solution necessary for the reaction and detection in the existing fully automatic acid value analyzer. The first electric push rod 25 squeezes the detection end at the top of the detection cup 15. Because the top edge of the detection cup 15 is provided with a rubber ring 16, the sleeve 36 will not move downward. At this time, the detection end moves downward along the slide rod 312, inserts the injection head assembly 311 into the detection cup 15, and at the same time, the stir bar 310 is put in to stir and mix while adding the detection liquid, and then... The acid value is measured by a sensor. The detection component 3, located at the top of the soaking tank 22, is first squeezed by the fourth electric push rod 210, causing the entire detection component 3 to move downward. The sleeve 36 is first inserted into the soaking tank 22 for soaking and cleaning. Then, the connecting end 35 is cleaned reciprocally by the third electric push rod 29. The injection head component 311 can also enter the soaking tank 22. Together with the anhydrous ethanol storage tank 21, the hose 37 is rinsed to clean the residual agent inside the detection component 3. During the subsequent rotation, the suspension effect can be used to dry it. At the same time, the dripping solution is recovered through the trough 17 at the tail end of the placement platform 12.

[0036] When using the device, add the sample to the detection cup 15, then open the door 11 and place the four sets of detection cups 15 onto the turntable 13. Close the door 11, and the drive motor 14 drives the turntable 13 to rotate. The transmission belt 18 also drives the turntable to rotate, and the four sets of detection cups 15 and the four sets of detection components 3 rotate synchronously and are used interchangeably to avoid contamination and to prevent dust from entering due to frequent opening of the door 11. The four sets of detection components 3 correspond one-to-one with the four sets of detection cups 15. The detection components 3 are inserted into the circular plate 31 through the insertion rod 32 and the first spring 33, and rotate together with the turntable 13. They are used interchangeably with the detection cups 15. When the detection component 3 located at the top of the detection cup 15 moves downward at the connecting end 35, the flexible tube 37 changes from a curved shape to a straight shape. The limiting sleeve 318 and the third spring 317 retract and move. Through the connection of the connecting rod 314 and the vertical plate 315, the vertical plate 315 moves laterally along the slide groove 38. At this time, the insertion post 39 of the vertical plate 315 leaves the insertion hole of the stirrer 310. When the stirrer 310 initially contacts the bottom of the detection cup 15, the detection end has not yet moved to its lowest point. Therefore, subsequent movement is simply achieved by the connecting rod 314 pushing the vertical plate 315 laterally to separate it from the stirrer 310. The stirrer 310 can then cooperate with the magnetic generator inside the placement platform 12 for stirring and mixing. This technology is existing. Simultaneously, during the stirring process, the sleeve 36 wraps around the top of the detection cup 15, preventing liquid splashing. Subsequently, under the elastic force of the second spring 313, the detection end moves laterally along the slide rod 318. 2. Slide upwards, the inserts 39 of the vertical plate 315 are reinserted into both ends of the stirrer 310, and are brought out of the test cup 15 for unified cleaning. Because the bottom of the sleeve 36 is flush with the top of the test cup 15, there will be no rotational interference. The two sets of test components 3 corresponding to the test cup 15 and the soaking tank 22 have hoses 37 at their tops that correspond to the connecting pipe 24 and the corrugated pipe 26, respectively. Because the corrugated pipe 26 of the anhydrous ethanol storage tank 21 is far away, the connecting frame 27 is moved downwards by the second electric push rod 28, and the corrugated pipe 26 unfolds until it connects with the top of the hose 37. Then, the hose 37 is clamped by the electromagnetic clamps 23 on both sides of the connecting pipe 24 and inside the connecting frame 27, keeping the hose 37 connected to the connecting pipe 24 and the corrugated pipe 26, respectively. The connection of tube 26 and the detection liquid delivery device 2 are for delivering the solution necessary for reaction and detection in the existing fully automatic acid value analyzer. The first electric push rod 25 squeezes the detection end at the top of the detection cup 15. Because the top edge of the detection cup 15 is provided with a rubber ring 16, the sleeve 36 will not move downward. At this time, the detection end moves downward along the slide rod 312, inserting the injection head assembly 311 into the detection cup 15. At the same time, the stir bar 310 is added to stir and mix while adding the detection liquid. The acid value is measured by the sensor. The detection assembly 3, located at the top of the soaking tank 22, is first squeezed by the fourth electric push rod 210, causing the entire detection assembly 3 to move downward. The sleeve 36 is first inserted into the soaking tank 22 for soaking and cleaning.Subsequently, the connecting end 35 is cleaned reciprocally by the third electric push rod 29. The injection head assembly 311 can also enter the immersion tank 22, and the tubing 37 is rinsed by the anhydrous ethanol storage tank 21 to clean the residual reagent inside the detection assembly 3. During subsequent rotation, it can be dried by utilizing the suspension effect, and the dripping solution is recovered through the trough 17 at the tail end of the placement platform 12.
