Description

Technical Field

[0001] The utility model relates to the technical field of resin viscosity detection, in particular to an on-line viscosity detection device for insulating resin. Background Art

[0002] Insulating paint is an important insulating product widely used at present, and is widely used in emerging green environmental protection industries such as photovoltaic inverters, rail transit, new energy vehicles and supporting facilities, and wind power. With the development of technology, people's requirements for the performance of insulating paint products are also increasing day by day. High-heat-grade polyamide-imide insulating resin is the main raw material for producing insulating paint, and the size of its molecular weight directly affects the performance and stability of the quality of insulating products. The viscosity of polyamide-imide insulating resin is an important parameter for detecting the quality of polyamide-imide insulating resin, and usually an on-line viscosity detection device is used to continuously detect the viscosity of polyamide-imide insulating resin at different temperatures. The on-line viscosity detection device mainly includes a data processor, a detection probe and an exciter for driving the detection probe to vibrate. The principle of the on-line viscosity detection device is mainly to place the vibratable detection probe in the polyamide-imide insulating resin. Since the detection probe vibrates in the flowing polyamide-imide insulating resin, it will lose energy due to the change of viscosity resistance, and the lost energy can be detected by the electronic circuit and converted into a displayable viscosity reading by a special data processor.

[0003] During the synthesis process of polyamide-imide insulating resin, the vibration of stirring will surely occur. In order to eliminate the influence of vibration, the on-line viscosity detection device needs to be installed outside the reaction kettle, and the polyamide-imide insulating resin in the reaction kettle is pumped out and input into the on-line viscosity detection device for continuous detection.

[0004] However, for the existing on-line viscosity detection device, due to continuously detecting the viscosity of insulating resin at different temperatures, the residual resin on the detection probe affects the result of the next detection, resulting in a decrease in the detection accuracy. Content of the Utility Model

[0005] Based on the above-mentioned prior art, the utility model provides an on-line viscosity detection device for insulating resin, which can reduce the residual resin on the detection probe, thereby improving the detection accuracy.

[0006] The technical solution adopted by the present utility model to solve its technical problems is: to provide an on-line viscosity detection device for insulating resin, including a detection box, a main body arranged on the detection box, a detection probe arranged on the main body, and a cleaning mechanism arranged in the detection box.

[0007] Further, a sliding groove is formed on the inner wall of the detection box. The moving component includes a rotating motor, a rotating screw rod rotatably arranged in the sliding groove, and a sliding block connected to the mounting rack. The output shaft of the rotating motor is coaxially fixed to the rotating screw rod. The rotating screw rod passes through the sliding block and is in threaded connection with the sliding block. The sliding block is slidably arranged in the sliding groove.

[0008] Further, the on-line viscosity detection device for insulating resin further includes a first collecting plate and a second collecting plate arranged on the mounting rack. The first collecting plate and the second collecting plate are respectively located on both sides of the mounting rack. The first collecting plate and the collecting plate are both located below the mounting rack.

The mounting semi-hole of the first collecting plate, the mounting semi-hole of the second collecting plate, and the cavity wall of the collecting cavity cooperate to form a closed space to collect the residual resin and cleaning solvent dropped from the detection probe.

[0009] Further, the on-line viscosity detection device for insulating resin further includes a connecting rod arranged on the main body. The diameter of the connecting rod is smaller than the diameter of the detection probe. One end of the connecting rod away from the main body is connected to the detection probe. The connecting rod is located in the detection box.

[0010] Further, a feed inlet and a discharge outlet are arranged on the detection box. The mounting rack is provided with a communication cavity communicated with both the spray head and the storage tank. The on-line viscosity detection device for insulating resin further includes a recovery tank communicated with the discharge outlet, a feeding pump arranged on the storage tank, and a communication pipe for communicating the feed inlet and the communication cavity. The collecting cavity corresponds to the discharge outlet. The second collecting plate is communicated with the recovery tank through the discharge outlet.

[0011] Further, the first collecting plate is provided with a first material guiding plate, and the second collecting plate is provided with a second material guiding plate. Both the first material guiding plate and the second material guiding plate are inclined.

[0012] Further, the positions of the feeding port and the discharging port correspond to the connecting rod. When the mounting frame drives the first material guiding plate and the second material guiding plate to move to the position of the connecting rod, the cleaning solvent and the residual resin in the collecting cavity enter the discharging port through the second material guiding plate.

[0013] Further, the height of the end of the first material guiding plate close to the mounting frame is lower than the height of the end of the first material guiding plate far from the mounting frame.

[0014] Further, the height of the end of the second material guiding plate close to the mounting frame is higher than the height of the end of the second material guiding plate far from the mounting frame.

[0015] Further, the mounting frame is of a cylindrical structure, and the mounting frame and the detection probe are coaxially arranged.

The mounting rack moves along the side wall of the detection probe through the moving component, and a spray head communicated with the storage tank is disposed on the mounting rack. The spray head is disposed towards the detection probe and is in contact with the detection probe. After the primary detection of the polyamide-imide insulating resin is completed, the moving component is used to control the mounting rack to move along the side wall of the detection probe. During the movement, the spray head sprays the cleaning solvent onto the detection probe, so that the adhesiveness of the residual resin adhering to the detection probe decreases and is scraped off along with the flow of the cleaning solvent. Thus, the residual resin on the detection probe can be reduced, thereby improving the detection accuracy. Description of the Drawings

The height of the mounting frame 41 is less than the height of the detection probe 30.

[0031] The mounting frame 41 is provided with a communication cavity 412 that is communicated with both the spray head 411 and the storage tank. The on-line viscosity detection device 100 for insulating resin further includes a pumping pump arranged on the storage tank and a communication pipe 512 for communicating the feed inlet 14 and the communication cavity 412.

[0033] The on-line viscosity detection device 100 for insulating resin further includes a first collection plate 43 and a second collection plate 44 disposed on the mounting bracket 41. The first collection plate 43 and the second collection plate 44 are located on both sides of the mounting bracket 41, and the first collection plate 43 and the second collection plate 44 are arranged in pairs with respect to the central axis of the mounting bracket 41. Further, in this embodiment, the first collection plate 43, the second collection plate 44, and the mounting bracket 41 are all fixedly connected. The sliding block 423 is fixedly connected to the first collection plate 43. Both the first collection plate 43 and the second collection plate 44 are slidably and sealingly connected to the inner wall of the detection box 10. Both the first collection plate 43 and the collection plate are located below the mounting bracket 41. The first collection plate 43 and the second collection plate 44 are both provided with a collection cavity 432 and a mounting half-hole 431 adapted to the detection probe 30. The mounting half-hole 431 of the first collection plate 43, the mounting half-hole 431 of the second collection plate 44, and the cavity wall of the collection cavity 432 cooperate to form a closed space to collect the residual resin dropped from the detection probe 30 scraped off by the nozzle 411.

[0034] The first collection plate 43 is provided with a first guide plate 433, and the second collection plate 44 is provided with a second guide plate 441. Both the first guide plate 433 and the second guide plate 441 are inclined.

The upper parts of both the first guide plate 433 and the second guide plate 441 are provided as cavities. The collection cavity 432 corresponds to the discharge port 141. The second collection plate 44 communicates with the recovery box through the discharge port 141. When the mounting bracket 41 drives the first guide plate 433 and the second guide plate 441 to move to the connecting rod 80, the cleaning solvent and the residual resin in the collection cavity 432 enter the discharge port 141 through the second guide plate 441. Specifically, in this embodiment, the height of the end of the first guide plate 433 close to the mounting bracket 41 is lower than the height of the end of the first guide plate 433 far from the mounting bracket 41. The height of the end of the second guide plate 441 close to the mounting bracket 41 is higher than the height of the end of the second guide plate 441 far from the mounting bracket 41, so that the cleaning solvent and the residual resin cannot flow back from the first collection plate 43 to the feed port 14, and can only flow along the second collection plate 44 to the discharge port 141.

[0035] The on-line viscosity detection device 100 for insulating resin further includes a flange 21 disposed on the main body 20 and a plurality of fixing bolts 22 adapted to the flange 21. The detection box 10 is provided with fixing holes 15 adapted to the fixing bolts 22, and the fixing bolts 22 are threadedly connected to the fixing holes 15.

[0036] Beneficial effects: After the primary detection of the polyamide-imide insulating resin is completed, the rotating motor 421 is started, so that the slider 423 drives the mounting bracket 41 to move along the side wall of the detection probe 30. During the movement, the spray head 411 sprays the cleaning solvent onto the detection probe 30, reducing the adhesiveness of the residual resin adhering to the detection probe 30, and being scraped off as the cleaning solvent flows. Thus, the residual resin on the detection probe 30 can be reduced, thereby improving the detection accuracy.

[0037] After the cleaning is completed, the rotating motor 421 is started, so that the slider 423 drives the mounting bracket 41, the first collecting plate 43, and the second collecting plate 44 to move along the side wall of the detection probe 30 to the connecting rod 80. At this time, the collecting cavity 432 is communicated with the discharge port 141 through the second guide plate 441. At the same time, the spray head 411 does not contact the detection probe 30 to avoid affecting the vibration of the detection probe 30. At the same time, the residual resin and the cleaning solvent scraped off from the detection probe 30 by the spray head 411 fall into the collecting cavity 432, and then move along the second guide plate 441, and finally enter the recycling box through the discharge port 141 and the pipeline for recycling or are output to the reaction kettle for continuous reaction.
