[0040] Beneficial effects of the present invention:

[0041] (1) By improving the emulsifying agitator, the connection assembly is used to realize the quick installation and removal of the stirring unit and the transmission shaft, thereby improving the convenience of replacing the stirring unit.

In the process of the self-locking protrusion entering the limiting groove, the transmission shaft applies force and compresses the spring to realize the energy storage action of the spring. Then, the connecting shaft is rotated at a certain angle so that the self-locking protrusion enters the inside of the limiting groove. After the transmission shaft is relaxed, the energy-storing spring will lift the connecting shaft, thereby locking the self-locking protrusion in the limiting groove, realizing the connection between the connecting shaft and the sleeve. At the same time, the quick connection between the stirring unit and the transmission shaft is also realized. It is convenient and quick, and no screws or other fixings are required, thereby reducing the difficulty of subsequent disassembly.

[0043] (3) When the emulsifying agitator is not in operation, the limiter is used to re-energize the spring, thereby reducing the thrust of the spring on the connecting shaft, allowing the connecting shaft to easily rotate and reset to the self-locking groove, and then gradually spiral outward to achieve rapid separation between the stirring unit and the transmission shaft. Compared with forcibly rotating the connecting shaft by brute force, the obstruction of the spring is eliminated in advance, allowing the disassembly action to be completed more smoothly, conveniently and quickly.

[0053] See also Figure 1-Figure 6 As shown, the present invention is a process for preparing high-quality textile pulp, comprising the following steps:

[0054] S1. Prepare raw materials, including polyether polyol, toluene-2,4-diisocyanate, 2,2-dihydroxymethylpropionic acid, diethylene glycol, acetone, triethylamine, and pure water;

[0057] S4, emulsification, add 165kg acetone and 10.5kg triethylamine into the reactor, stir well, slowly add 1003.5kg pure water, and turn on the emulsification stirrer to stir until a uniform emulsion is formed;

[0058] S5. Sampling inspection and post-processing: sampling from the emulsion for quality inspection to ensure that all indicators meet product requirements;

[0059] The qualified slurry is then filtered through a filter to remove impurities and unreacted raw material particles, and then the filtered slurry is transferred to a clean packaging container and sealed for storage to obtain a finished product;

[0060] Among them, the emulsifying blender in S4 includes a controller, a motor 1 and a stirring mechanism 2, the motor 1 is connected to the stirring mechanism 2 in a transmission manner, the stirring mechanism 2 includes a plurality of stirring units 21 and a transmission shaft 22, the stirring units 21 are arranged on the transmission shaft 22 and are distributed at equal intervals, and the stirring units 21 are all installed on the transmission shaft 22 through a connecting component 23.

[0061] In order to solve the problems raised in the background technology, the present invention improves the emulsifying agitator and utilizes the connecting component 23 to realize the quick installation and disassembly of the stirring unit 21 and the transmission shaft 22, thereby improving the convenience of replacing the stirring unit 21. The stirring units 21 of different specifications can be replaced as needed to meet the emulsification needs of different stirring ranges, and the practical value is high.

[0062] Further, the connecting assembly 23 includes a connecting shaft 231 and a sleeve 232, the end of the connecting shaft 231 is fixed on the stirring unit 21, one end of the sleeve 232 is fixedly arranged on the transmission shaft 22, and the other end is slidably connected to the connecting shaft 231, a self-locking groove 233 is arranged inside the sleeve 232, and the self-locking groove 233 is arranged in a spiral structure, a limiting groove 234 connected to the self-locking groove 233 is arranged on the inner side wall of the sleeve 232, a spring 235 is fixedly arranged on the inner bottom wall of the sleeve 232, and a self-locking protrusion 236 is fixed on the connecting shaft 231, and the self-locking protrusion 236 is slidably matched with the self-locking groove 233;

[0063] When the self-locking protrusion 236 slides to the bottom along the self-locking groove 233, it can compress the spring 235 and rotate into the limiting groove 234, thereby realizing self-locking between the connecting shaft 231 and the sleeve 232 by utilizing the elastic force of the compression spring 235;

[0064] The sleeve 232 is also provided with a limiter 24 , and the limiter 24 works when the connecting shaft 231 and the sleeve 232 are disassembled, and the limiter spring 235 is in a compressed state.

[0065] The present invention provides a specific connecting assembly 23 mechanism. When in use, after the connecting shaft 231 is aligned with the sleeve 232 to be installed, the self-locking protrusion 236 on the connecting shaft 231 is aligned with the self-locking groove 233 in the sleeve 232, so that the connecting shaft 231 spirally enters into the bottom of the sleeve 232 along with the self-locking protrusion 236 until the self-locking protrusion 236 enters into the limiting groove 234 connected to the self-locking groove 233. At this time, the connecting shaft 231 and the sleeve 232 are still in a free state. In order to realize the change from the free connection state of the two to the connection limit state, a spring 235 is provided. When the self-locking protrusion 236 enters During the process of entering the limit groove 234, the transmission shaft 22 applies force and compresses the spring 235 to realize the energy storage action of the spring 235, and then rotates the connecting shaft 231 at a certain angle so that the self-locking protrusion 236 enters the interior of the limit groove 234. After relaxing the transmission shaft 22, the energy-storing spring 235 will lift the connecting shaft 231, and then the self-locking protrusion 236 will be locked in the limit groove 234, realizing the connection between the connecting shaft 231 and the sleeve 232, and also realizing the quick connection between the stirring unit 21 and the transmission shaft 22, which is convenient and quick without the use of screws and other fixings, thereby reducing the difficulty of subsequent disassembly.

[0066] Further, the limiter 24 includes an electromagnet 241, the electromagnet 241 is fixedly arranged at the middle of the inner bottom wall of the sleeve 232, the electromagnet 241 is arranged in an annular structure, the spring 235, the connecting shaft 231, and the sleeve 232 are all made of non-ferromagnetic materials, and an annular iron 242 is arranged on the spring coil of the spring 235 away from the electromagnet 241, the electromagnet 241 and the motor 1 are electrically connected to the controller, and the motor 1 is also installed with a sensor 243, and the sensor 243 is used to detect the motion state of the motor 1 and send the detection signal to the controller;

[0067] When the sensor 243 detects that the motor 1 is in a moving state, the detected moving state signal is sent to the controller, and the controller cuts off the power to the electromagnet 241 after receiving the moving state signal; when the sensor 243 detects that the motor 1 is in a stopped state, the detected stopped state signal is sent to the controller, and the controller turns on the power to the electromagnet 241 after receiving the stopped state signal.

[0068] In the present invention, in order to reduce the connection state between the connecting shaft 231 and the sleeve 232 for subsequent disassembly, it is necessary to temporarily reduce the pushing force of the energy-accumulating spring 235 on the connecting shaft 231, so a limiter 24 is provided. When the emulsifying agitator is in a non-working state as a whole, the limiter 24 is used to re-accumulate the spring 235, thereby reducing the pushing force of the spring 235 on the connecting shaft 231, so that the connecting shaft 231 can be easily rotated and reset to the self-locking groove 233, and then gradually spirally withdraw the connecting shaft 231 outward to achieve the rapid separation between the stirring unit 21 and the transmission shaft 22. Compared with forcibly rotating the connecting shaft 231 by brute force, the obstruction of the spring 235 is eliminated in advance, so that the disassembly action can be completed more smoothly and conveniently. In order to avoid the limiter 24 being in the above-mentioned quick-release state during the entire working process of the emulsifying agitator shaft, the limiter 24 is 24 is restricted in structure and connection state, and the detection of sensor 243 is utilized, so that when motor 1 is in motion, electromagnet 241 is powered off and demagnetized, so that electromagnet 241 cannot generate magnetism to annular iron 242, and thus spring 235 is always in a state of pressing against connecting shaft 231, and at this time, stirring unit 21 and transmission shaft 22 are in a firmly connected state, and when sensor 243 detects that motor 1 is in shutdown state, controller controls electromagnet 241 to be powered on and magnetized, and the strong magnetism generated strongly adsorbs annular iron 242 at the end of spring 235, so that spring 235 can re-store energy, and thus can be in a convenient and quick-disassembly state, and in summary, when motor 1 is in shutdown state, it is in a quick-disassembly state, and when motor 1 is in working state, it is in a firmly connected state, and plays a role of selectively quickly disassembling and quickly installing stirring unit 21, which conforms to the actual situation and has practical value.

[0069] Furthermore, the transmission shaft 22 is configured as a telescopic structure, and the transmission shaft 22 includes a first transmission shaft 221 and a second transmission shaft 222. Telescopic sleeves 223 are provided on the outer sides of the first transmission shaft 221 and the second transmission shaft 222. Through grooves are provided on both sides of the telescopic sleeve 223. The first transmission shaft 221 is fixedly connected to the telescopic sleeve 223, and the second transmission shaft 222 is slidingly and sealingly connected to the through groove. The first transmission shaft 221 and the second transmission shaft 222 are connected by an automatic telescopic rod 224, and the automatic telescopic rod 224 is located inside the telescopic sleeve 223.

[0070] The present invention sets the transmission shaft 22 as a telescopic structure, so that the stirring depth can be adjusted according to the temperature change during the emulsification stirring process. Since the longer the transmission shaft 22, the greater the stirring depth, the larger the stirring range, and the stronger the stirring intensity, the emulsified liquid will be heated up. Once the temperature exceeds the standard, the viscosity of the liquid will decrease, and the surface tension will also change, thereby affecting the emulsification effect; therefore, the present invention sets the transmission shaft 22 as a telescopic structure. When the emulsification temperature increases, the length of the transmission shaft 22 can be shortened to achieve the purpose of reducing the stirring depth and stirring range, thereby reducing the emulsification temperature rise. Through the above process, the stirring depth and stirring range can be flexibly changed as needed.

[0071] The sleeve 232 is provided with an auxiliary mechanism 3, and the auxiliary mechanism 3 is used to assist in connecting the sleeve 232 and the connecting shaft 231; the auxiliary mechanism 3 includes a through slot 31 and a sliding member 32;

[0072] The second transmission shaft 222 is provided with a through groove 31, and a sliding member 32 is slidably installed in the through groove 31. The second transmission shaft 222 is provided with an electromagnetic part 4, and the electromagnetic part 4 is opposite to the sliding member 32. The electromagnetic part 4 is electrically connected to the controller. The sliding member 32 is connected to a linkage member 33, and the linkage member 33 is movably connected in a movable groove 35 provided inside a fixed member 34. The linkage member 33 is located in the movable groove 35 and slides horizontally. The fixed member 34 is fixedly provided at the end of the sleeve 232, and a swinging member 391 is hinged at the end of the linkage member 33. The middle part of the swinging member 391 is hinged on the inner side wall of the movable groove 35. A clamping assembly 39 is provided at the bottom of the swinging member 391, and the clamping assembly 39 includes a pressing member 392. The bottom of the swinging member 391 contacts the top of the pressing member 392, and a sliding portion 37 is provided on one side of the pressing member 392. The sliding portion 37 is slidably mounted on a vertical groove 36 provided on the inner wall of the movable groove 35, and a reset member 38 (which may be a reset spring) is provided on the bottom wall of the vertical groove 36. A clamping groove is provided on the connecting shaft 231 at a clamping portion 393 provided at the bottom of the pressing member 392. When the connecting shaft 231 enters into the sleeve 232 and is in place, the clamping portion 393 of the pressing member 392 just falls into the clamping groove.

[0073] In order to achieve the sealing of the connection between the sleeve 232 and the connecting shaft 231 and to strengthen the connection stability between the sleeve 232 and the connecting shaft 231, the present invention provides an auxiliary mechanism 3. When in use, when the electromagnetic part 4 is energized, the magnetic attraction will adsorb the sliding member 32 in the through groove 31, so that the sliding member 32 slides laterally toward the inside of the transmission shaft 222, thereby pulling the end of the connected swinging member 391, so that the end of the swinging member 391 swings along the middle, so that the bottom of the swinging member 391 swings to the side away from the transmission shaft 222, and the pressing member 392 pushes the top of the swinging member 391 to move the bottom of the swinging member 391 away from the transmission shaft 222. The lower end of the swinging member 391 which is always in contact with the top surface of the pressing member 392 will force the pressing member 392 to overcome the supporting force of the reset member 38 and move downward until the clamping portion 393 at the bottom of the pressing member 392 is engaged with the clamping groove on the connecting shaft 231, thereby achieving the clamping fixation of the fixing member 34 and the connecting shaft 231, thereby playing a reinforcing role. At the same time, when the clamping portion 393 and the clamping groove (not shown in the figure) are connected, a sealing reinforcement effect is formed between the sleeve 232 and the connecting shaft 231, thereby avoiding the adverse effects caused by the slurry entering the interior of the sleeve 232 as much as possible.

[0074] Furthermore, the stirring mechanism 2 also includes a control module for adjusting the telescopic length of the transmission shaft 22, and the control module is used to adjust the stirring length according to the temperature of the emulsified liquid. The working process of the control module is:

[0075] Real-time detection of the temperature value of the emulsified liquid during emulsification and stirring based on the temperature sensor;

[0076] Obtaining the rotation speed value of the transmission shaft 22, the current length of the transmission shaft 22, and the extension of the automatic telescopic rod 224;

[0077] According to the deviation between the temperature rise curve ST(t) of the temperature value of the emulsified liquid per unit time and the reference temperature rise curve RT(t), it is judged whether the temperature of the emulsified liquid exceeds the standard, and the automatic telescopic rod 224 is controlled to extend, maintain or shorten according to the judgment result.

[0078] The process of judging whether the temperature of the emulsified liquid exceeds the standard is as follows:

[0079] Substitute the obtained ST(t) and RT(t) into the following formula:

[0080]

[0081] The temperature rise deviation value PT of the emulsified liquid is calculated;

[0082] Compare the temperature rise deviation value PT with the temperature rise deviation threshold interval [PT0, PT1];

[0083] If PT>PT1, it is judged that the temperature of the emulsified liquid exceeds the standard; if PT∈[PT0, PT1], it is judged that the temperature of the emulsified liquid is normal; if PT<PT1, it is judged that the temperature of the emulsified liquid is too low;

[0084] In the formula, i is the i-th unit time, n is the number of unit time, μ is the μ-th unit time, ρ μ is the weight coefficient, determined based on historical data analysis, t i ,t i+1 are two time endpoints of unit time.

[0085] The process of controlling the automatic telescopic rod 224 to adjust according to the judgment result is:

[0086] Substitute the obtained rotation speed value Z of the transmission shaft 22, the current length L of the transmission shaft 22, the elongation l1 of the automatic telescopic rod 224, and the temperature value T of the emulsified liquid into the following formula group:

[0087] T = Z × ɑ + L × β;

[0088] L = l2 + cl1 + cl2;

[0089] Calculate the theoretical extension l2 of the automatic telescopic rod 224;

[0090] Adjust the extension of the automatic telescopic rod 224 from l1 to l2;

[0091] In the formula, cl1 is the length value of the first transmission shaft 224, cl2 is the length value of the second transmission shaft 222, ɑ and β are weight coefficients, which are dynamically assigned based on historical experience data.

[0092] In order to reduce the situation that the temperature rise of the emulsified liquid is abnormal during the emulsification process due to the stirring depth problem of the emulsifying stirrer, thereby affecting the emulsification quality, the present invention analyzes a method for judging whether the temperature of the emulsified liquid exceeds the standard, and provides a method for adjusting the temperature of the emulsified liquid by adjusting the length of the transmission shaft. Specifically, the temperature rise change curve ST(t) of the temperature value of the emulsified liquid per unit time and the reference temperature rise curve RT(t) are first obtained, and then the formula is used: The temperature rise deviation value PT of the emulsified liquid is calculated; by analyzing the accumulated temperature rise variation amplitude in multiple historical unit time periods, and then comparing it with the temperature rise deviation threshold range, if the accumulated variation amplitude, i.e., the temperature rise deviation value PT, falls within the range, it means that the temperature of the emulsified liquid is normal; if it exceeds the range, it means that the temperature is too high; if it is lower than the range, it means that the temperature is too low, thereby accurately judging whether the temperature of the emulsified liquid is abnormal or not, and providing data support for the subsequent adjustment of the drive shaft length to change the stirring depth and range;

[0093] At the same time, the obtained rotational speed value Z of the transmission shaft 22, the current length L of the transmission shaft 22, the elongation l1 of the automatic telescopic rod 224 and the temperature value T of the emulsified liquid are substituted into the formula group: T=Z×ɑ+L×β; L=l2+cl1+cl2; the theoretical elongation l2 of the automatic telescopic rod 224 is calculated; the elongation of the automatic telescopic rod 224 is adjusted from l1 to l2, thereby realizing dynamic adjustment of the elongation of the automatic telescopic rod.

[0094] It should be noted that the calculation formulas and various parameters involved in the calculation in the present invention have been dimensionally processed in advance, and the process of dimensionless processing is well known in the industry and will not be described here.

[0095] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
