Description

Technical Field

[0001] The present invention relates to the technical field of ethylene tar stabilizer detection, and particularly to a viscosity detection device for ethylene tar stabilizers. Background Art

[0002] During the production process of ethylene tar stabilizers, it is necessary to detect the viscosity of ethylene tar stabilizers. The stability of the viscosity of ethylene tar stabilizers is directly related to their use effect and product quality.

[0003] Currently, capillary viscometers are usually used to detect the viscosity of ethylene tar stabilizers. However, in order to prevent impurities or residues from the previous detection from remaining in the capillary viscometer, these substances may react with the ethylene tar stabilizer or interfere with its flow, thereby affecting the measurement result of the viscosity. Therefore, it is necessary to clean the inside of the capillary viscometer to remove the residues in the capillary viscometer. Usually, the required cleaning agent is manually poured into the capillary viscometer, and then the cleaning agent in the capillary viscometer is aspirated by an ear syringe, so that the cleaning agent continuously circulates in the capillary viscometer to achieve the washing effect. However, the operator needs to continuously move the position of the ear syringe and block specific positions by hand to complete a comprehensive cleaning, which is cumbersome and affects the subsequent detection efficiency of the viscosity of ethylene tar stabilizers.

[0004] Therefore, it is necessary to design a viscosity detection device for ethylene tar stabilizers that can automatically aspirate the cleaning agent in the capillary viscometer to complete a comprehensive cleaning, is convenient to operate, and improves the subsequent detection efficiency of the viscosity of ethylene tar stabilizers. Summary of the Invention

[0014] The beneficial effects of the present invention are as follows: 1. First, the viscosity of the sample of the ethylene tar stabilizer is detected by the capillary viscometer. After the viscosity detection, the cleaning agent is poured into the capillary viscometer. The right cylinder is started to drive the right hollow plug to move downward through the fixed plate to block the air inlet pipe.

A suction component is arranged between the frame 1 and the hollow plug 11. The suction component can suck the cleaning agent in the capillary viscometer 4 through the hollow plug 11 so that the cleaning agent flows to clean the inside of the capillary viscometer 4. A circulation component is arranged on the frame 1. When the circulation component operates, the circulation component can complete the discharge and intake of water in the frame 1.

[0031] Please refer to Figure 2 As shown, the circulation component includes a drain pipe 7, a circulation pump 71 and a liquid storage cylinder 72. The drain pipe 7 is connected to the right front side of the bottom of the frame 1. The drain pipe 7 can discharge the water in the frame 1. A liquid storage cylinder 72 is installed on the right rear side of the frame 1. A circulation pump 71 is fixedly connected to the right front side of the frame 1 in an embedded manner. One end of the circulation pump 71 is communicated with the inside of the frame 1, and the other end of the circulation pump 71 is connected to the lower part of the front side of the liquid storage cylinder 72.

[0032] Please refer to Figure 3 and Figure 5As shown, the suction assembly includes a single-rod cylinder block 13, an air supply pipe 131, a rack 132, a drive motor 133, and a spur gear 134. The single-rod cylinder blocks 13 are symmetrically and fixedly connected to the left and right at the rear of the inner side of the frame body 1. The upper parts of the mutually approaching sides of the left and right single-rod cylinder blocks 13 are both connected with the air supply pipe 131. The tail ends of the left and right air supply pipes 131 are respectively connected to the tops of the left and right hollow plugs 11. The bottom ends of the piston rods of the left and right single-rod cylinder blocks 13 are both fixedly connected with the rack 132. A drive motor 133 is installed in the middle of the inner side of the frame body 1. A spur gear 134 is fixedly sleeved on the output shaft of the drive motor 133. The spur gear 134 meshes with the left and right racks 132.

[0033] Please refer to Figure 6 As shown, the drive assembly includes a worm gear 14, a stepper motor 141, and a worm 142. The worm gear 14 is fixedly sleeved on the rear side of the mounting bracket 31. The stepper motor 141 is installed on the right part of the frame body 1. The end of the output shaft of the stepper motor 141 is fixedly connected with the worm 142. The worm 142 meshes with the worm gear 14.

[0034] Initially, the liquid filling cylinder 72 is filled with an appropriate amount of clear water. First, start the circulation pump 71 to pump the clear water in the liquid filling cylinder 72 into the frame 1. The clear water in the frame 1 contacts the heating pipe 6. Subsequently, start the heating pipe 6 to heat the clear water in the frame 1 until the clear water reaches the required temperature. The capillary viscometer 4 is then immersed in the warm water. Then, pour the sample of the ethylene tar stabilizer into the capillary viscometer 4. The capillary viscometer 4 measures the viscosity of the sample. The operator can observe the flow of the sample in the tube body through the transparent plate 2. Start timing when the liquid level just reaches the marking line, and stop timing when the liquid level just flows to another marking line. Repeat the measurement at least four times, and take the arithmetic mean as the average flow time of the sample. Calculate the viscosity of the sample based on the measured average flow time and the capillary constant. When the viscosity detection of the sample is completed, start the circulation pump 71 to pump the clear water in the frame 1 back into the liquid filling cylinder 72. Then, start the stepping motor 141 to drive the worm 142 to rotate. The rotation of the worm 142 drives the worm gear 14 to rotate. The rotation of the worm gear 14 drives the mounting bracket 31 to rotate. The mounting bracket 31 drives the capillary viscometer 4 to rotate. When the liquid inlet end of the capillary viscometer 4 faces downward, turn off the stepping motor 141, and all the sample in the capillary viscometer 4 is discharged and dropped into the frame 1. Start the stepping motor 141 to drive the worm 142 to rotate in the reverse direction. The worm 142 drives the mounting bracket 31 to rotate in the reverse direction through the worm gear 14. The mounting bracket 31 drives the capillary viscometer 4 to rotate in the reverse direction and return to the vertical state. Subsequently, pour the cleaning agent into the air inlet pipe 43 of the capillary viscometer 4. The cleaning agent in the air inlet pipe 43 is discharged into the lower part inside the measuring tube 41 of the capillary viscometer 4. Start the right cylinder 9. The telescopic rod of the right cylinder 9 extends to drive the right fixed plate 10 to move downward. The right fixed plate 10 drives the right hollow plug 11 to move downward. The downward movement of the right hollow plug 11 blocks the end of the air inlet pipe 43 of the capillary viscometer 4. Turn off the right cylinder 9. Start the drive motor 133 to drive the spur gear 134 to rotate forward and backward alternately. The forward and backward alternating rotation of the spur gear 134 drives the rack 132 to move up and down. The upward movement of the right rack 132 drives the piston rod of the right single-rod cylinder body 13 to move upward, so that the air in the right single-rod cylinder body 13 is pushed into the right air supply pipe 131. The air in the right air supply pipe 131 is discharged into the right hollow plug 11. The air in the right hollow plug 11 is discharged into the air inlet pipe 43 of the capillary viscometer 4. The inflow of air pushes the cleaning agent in the capillary viscometer 4 to flow, so that the cleaning agent is discharged into the vent pipe 42. The cleaning agent then cleans the inside of the vent pipe 42. When the right rack 132 moves downward, the right rack 132 drives the piston rod of the single-rod cylinder body 13 to move downward and reset, and then the air in the air inlet pipe 43 is pumped out through the right air supply pipe 131 and the right hollow plug 11. Repeating this way, the air inlet pipe 43 can be continuously suction-treated, so that the cleaning agent reciprocates to flow and clean the inside of the vent pipe 42. When the inside of the vent pipe 42 is cleaned, start the middle cylinder 9,The telescopic rod of the middle cylinder 9 extends to drive the middle fixed plate 10 to move downward. The middle fixed plate 10 drives the rubber sleeve 12 to move downward. The downward movement of the rubber sleeve 12 blocks the emptying pipe 42. The middle cylinder 9 is closed. At this time, air pushes the cleaning agent into the measuring pipe 41, so that the cleaning agent flows back and forth in the measuring pipe 41 for cleaning. When the measuring pipe 41 is cleaned, start the cylinders on the right side and in the middle. Driven by the fixed plate 10, the right hollow plug 11 and the rubber sleeve 12 move upward to reset. Then start the left cylinder 9. The left cylinder 9 drives the left hollow plug 11 to move downward through the left fixed plate 10. The downward movement of the left hollow plug 11 blocks the measuring pipe 41 of the capillary viscometer 4. The left cylinder 9 is closed. At this time, start the drive motor 133 to drive the spur gear 134 to rotate forward and backward alternately. The forward and backward alternating rotation of the spur gear 134 drives the left rack 132 to move up and down. The up and down movement of the left rack 132 drives the piston rod of the left single-rod cylinder block 13 to move up and down. The left single-rod cylinder block 13 is connected to the left hollow plug 11 through the left air supply pipe 131 to perform a suction process on the measuring pipe 41. When all the cleaning agent in the measuring pipe 41 is pushed to the inner lower part, turn off the drive motor 133, start the left cylinder 9, and drive the left hollow plug 11 to move upward to reset through the left fixed plate 10. Then start the stepping motor 141 again to drive the worm 142 to rotate, so that the mounting bracket 31 drives the capillary viscometer 4 to rotate into an inclined state, so that all the cleaning agent in the capillary viscometer 4 is poured out. Then start the stepping motor 141 to drive the worm 142 to rotate in the reverse direction, so that the mounting bracket 31 drives the capillary viscometer 4 to rotate in the reverse direction to reset. In this way, the automatic suction of the cleaning agent in the capillary viscometer 4 can be completed to achieve a comprehensive cleaning, without the need for manual cooperation with an ear bulb for cleaning, which is convenient to operate, thereby improving the detection efficiency of the viscosity of the subsequent ethylene tar stabilizer. Finally, start the drain pipe 7 to drain the used cleaning agent in the frame 1 for treatment.,

[0035] Please refer to Figure 7 As shown, the viscosity detection device for ethylene tar stabilizer further includes a positioning component installed between the mounting bracket 31 and the frame 1. The positioning component includes a cross plate 15, a fixed frame 151, a drive plate 152, a screw 153 and a circular frame 154. The cross plate 15 is fixedly sleeved on the rear side of the mounting bracket 31. The cross plate 15 is located behind the worm gear 14. The fixed frame 151 is fixedly connected to the upper right side inside the frame 1. The fixed frame 151 is inclined. The drive plate 152 is slidably connected to the inside of the fixed frame 151. The end of the drive plate 152 is triangular. The end of the drive plate 152 faces the cross plate 15. When the drive plate 152 moves into contact with the cross plate 15, the drive plate 152 can position the cross plate 15. The screw 153 is rotatably penetrated through the fixed frame 151. The screw 153 is threadedly connected to the rear side of the drive plate 152. The top of the screw 153 is fixedly connected to the circular frame 154.

[0036] Please refer toFigures 8 - 10 As shown, the viscosity detection device for ethylene tar stabilizer further includes a liquid supply component installed between the frame 1 and the console 3. The liquid supply component includes a liquid extraction pump 16, a hose 161, a hollow ball 162, a liquid extraction pipe 163, a cylinder 164, and a switching component. The liquid extraction pump 16 is fixedly connected to the lower left side of the front surface of the console 3. The liquid outlet end of the liquid extraction pump 16 is connected to the hose 161. The tail end of the hose 161 is connected to the upper part of the capillary viscometer 4. The hose 161 can discharge the cleaning agent into the capillary viscometer 4. The liquid extraction end of the liquid extraction pump 16 is connected to the hollow ball 162. Four liquid extraction pipes 163 are evenly spaced along the circumferential direction at the lower part of the hollow ball 162. Four cylinders 164 are fixedly connected to the left side of the frame 1. The tops of the four cylinders 164 are respectively connected to the liquid inlet ends of the four liquid extraction pipes 163. A switching component is arranged between the hollow ball 162 and the frame 1. When the switching component operates, the switching component can switch different types of cleaning agents. The switching component includes a servo motor 165 and a ball valve 166. The ball valve 166 is rotatably connected to the inner side of the hollow ball 162. The channel of the ball valve 166 is L-shaped and corresponds to the liquid extraction pipe 163. The servo motor 165 is installed on the left side of the top of the frame 1. The end of the output shaft of the servo motor 165 is fixedly connected to the bottom end of the ball valve 166.

[0037] When it is necessary to detect the viscosity of the sample of the ethylene tar stabilizer, first turn the circular frame 154 clockwise. The clockwise rotation of the circular frame 154 drives the screw 153 to rotate clockwise. The clockwise rotation of the screw 153 drives the driving plate 152 to move left and downward. The driving plate 152 moves left and downward and contacts the right angle of the cross plate 15. The driving plate 152 pushes the cross plate 15 to rotate. The cross plate 15 drives the capillary viscometer 4 to rotate through the mounting frame 31, so as to correct the deviation and position the capillary viscometer 4. When the driving plate 152 is completely attached to the right angle of the cross plate 15, stop turning the circular frame 154, and the driving plate 152 stops moving left and downward. At this time, the cross plate 15 and the capillary viscometer 4 are in a vertical state, and subsequent detection and processing can be started. When the viscosity detection is completed, turn the circular frame 154 counterclockwise to drive the screw 153 to rotate counterclockwise. The counterclockwise rotation of the screw 153 drives the driving plate 152 to move right and upward to reset. The driving plate 152 resets and disengages from the cross plate 15, so as not to affect the rotation of the capillary viscometer 4 to pour out the sample and the cleaning agent. In this way, it is possible to prevent the capillary viscometer 4 from being in an inclined state and affecting the accuracy of the viscosity detection of the sample, thereby ensuring the accuracy of the sample viscosity detection.

[0038] ​Initially, different types of cleaning agents are contained in the four cylinders 164. When it is necessary to clean the inner side of the capillary viscometer 4 after use, the liquid extraction pump 16 is started. The liquid extraction pump 16 pumps the cleaning agent in the cylinder 164 into the corresponding liquid extraction pipe 163. The cleaning agent in the liquid extraction pipe 163 is discharged into the ball valve 166 through the sphere. The cleaning agent in the ball valve 166 is discharged into the hose 161 by the liquid extraction pump 16. The cleaning agent in the hose 161 is discharged into the air inlet pipe 43 of the capillary viscometer 4. The liquid extraction pump 16 is turned off, and then the cleaning of the inner side of the capillary viscometer 4 can begin. When another cleaning agent is needed for cleaning, the servo motor 165 is started to drive the ball valve 166 to rotate. When the ball valve 166 rotates to correspond to the liquid extraction pipe 163 that discharges the required cleaning agent, the servo motor 165 is turned off, and then the liquid extraction pump 16 can be started again to make the required cleaning agent be discharged into the capillary viscometer 4. In this way, it is more convenient to add different types of cleaning agents, thereby improving the cleaning efficiency.

[0039] Please refer to Figure 11 As shown, the viscosity detection device for the vinyl tar stabilizer further includes a filter plate 17. The filter plate 17 is fixedly connected to the right side of the bottom of the frame body 1 in an embedded manner. The filter plate 17 corresponds to the liquid inlet end of the drain pipe 7. When water contacts the filter plate 17, the filter plate 17 can filter the impurities in the water.

[0040] When the drain pipe 7 is started, the cleaning agent in the frame body 1 first contacts the filter plate 17. The filter plate 17 filters the impurities in the cleaning agent. The cleaning agent after filtering the impurities is discharged through the drain pipe 7. In this way, it can prevent the impurities in the cleaning agent from adhering in the drain pipe 7 and causing blockage, thereby ensuring the normal use of the drain pipe 7.
