[0002] Ester quaternary ammonium salt is a new type of cationic surfactant with excellent softening, antistatic and anti-yellowing properties. It does not contain APEO and formaldehyde, is easily biodegradable and environmentally friendly. It has a small dosage, good effect, convenient preparation, low overall cost and extremely high cost performance. It is the best substitute for dioctadecyl dimethyl ammonium chloride (D1821), film, softener, etc.

[0003] In the preparation of existing ester-based quaternary ammonium salts, generally, a single stirring device is used to assist in mixing and stirring the ester-based quaternary ammonium salt raw material and the acidic liquid.

[0016] A technical solution proposed by the present invention: a method for preparing an ester quaternary ammonium salt, comprising the following steps:

[0017] S1. Before preparing the ester quaternary ammonium salt, the liquid raw material for preparing the ester quaternary ammonium salt and the liquid of the mixed ester quaternary ammonium salt liquid raw material need to be injected into the stirring tank, and as the external motor is started, the third connecting rod and the liquid outlet pipe will rotate, thereby completing the mixing and stirring of the mixed liquid;

[0018] S2, by setting a rotating base on the top of the mixing tank, and a plurality of extrusion blocks are set on the rotating base, so when the connecting rod rotates, the extrusion block will drive the second connecting rod to move up and down intermittently;

[0019] S3. When the second connecting rod moves up and down intermittently, the liquid outlet pipe and the third connecting rod can not only complete the layered stirring of the mixed liquid, but also move left and right, thereby increasing the stirring range of the liquid outlet pipe and the third connecting rod, so as to effectively improve the stirring efficiency of the mixed liquid;

[0020] S4. When the mixed liquid inside the stirring tank is thoroughly mixed, the user can discharge the mixed ester quaternary ammonium salt liquid out of the stirring tank through the discharge pipe, thereby completing the corresponding collection.

[0021] The present invention has the following beneficial effects:

[0022] 1. The ester-based quaternary ammonium salt preparation device is provided with an inner core rod inside the connecting rotating rod, and a plurality of sets of third connecting rods and liquid outlet pipes are provided on the inner core rod. This arrangement not only allows the liquid of the mixed ester-based quaternary ammonium salt liquid raw material and the liquid raw material for preparing the ester-based quaternary ammonium salt to achieve a mixing effect, but also through the rotation of the connecting rotating rod, the plurality of liquid outlet pipes and the third connecting rod can effectively complete the stirring between the two, so as to effectively accelerate the mixing efficiency between the two.

[0023] 2. The ester-based quaternary ammonium salt preparation device, through the setting of the first arc-shaped movable groove, allows the third connecting rod to rotate accordingly when following the inner core rod to make intermittent up and down movements, so that the liquid outlet pipe can also move left and right a certain distance, and this setting also effectively changes the mixing point between the mixed liquids, so that the liquids of the mixed ester-based quaternary ammonium salt liquid raw materials at different positions can be mixed with the liquid raw materials for preparing the ester-based quaternary ammonium salt to a certain extent, so as to improve the mixing efficiency between the two. Moreover, changing the position of the liquid outlet pipe also allows the liquid outlet pipe to further improve the stirring range of the liquid raw materials for preparing the ester-based quaternary ammonium salt and the liquid of the mixed ester-based quaternary ammonium salt liquid raw materials, thereby effectively improving the mixing efficiency between the two.

[0024] 3. The ester-based quaternary ammonium salt preparation device drives the rotating base and several extrusion blocks to rotate accordingly by moving the connecting rack, and this rotation will change the position of the extrusion block. When the connecting rod rotates again, the position of the extrusion block changes, which causes the inner core rod to reciprocate up and down, thereby changing the raw material injection point of the third connecting rod. Through such a setting, the raw material injection point position of the third connecting rod when the rotating base does not change the position of the extrusion block and the raw material injection point position of the third connecting rod when the position of the extrusion block is changed are changed. By changing the position of the extrusion block, the highest raw material injection position of the third connecting rod is changed to the lowest raw material injection position. In this way, the dispersion of the raw material injection is further improved, and the mixing effect is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] A connecting spring 125 is also provided between the inner core rod 113 and the connecting rotating rod 103 . The inner core rod 113 is slidably arranged inside the corresponding second movable groove 122 through a corresponding slider. The second movable groove 122 is provided at the inner wall of the connecting rotating rod 103 .

[0044] A first feed pipe 101 and a discharge pipe 102 are also provided on the surface of the stirring tank 1. The first feed pipe 101 and the discharge pipe 102 are both connected to the interior of the stirring tank 1. A second feed pipe 123 is provided on the connecting rotating rod 103. The second feed pipe 123 is slidably set inside the third movable groove 124, and one end of the second feed pipe 123 is connected to the interior of the liquid storage pipe 127.

[0045] A plurality of extrusion blocks 107 are arranged between the two limiting ring plates 106 . The plurality of extrusion blocks 107 are arranged equidistantly with the connecting rotating rod 103 as the center. One end of a second connecting rod 110 is also arranged between the plurality of extrusion blocks 107 and between two adjacent extrusion blocks 107 .

[0046] The other end of the second connecting rod 110 is fixedly connected to the first connecting rod 109 . The first connecting rod 109 is slidably disposed inside the first movable groove 111 , and the other end of the first connecting rod 109 is fixedly connected to the inner core rod 113 .

[0047] In the present embodiment: before preparing the ester-based quaternary ammonium salt, on the one hand, the liquid raw material for preparing the ester-based quaternary ammonium salt needs to be injected into the liquid storage tube 127 through the second feed pipe 123, and on the other hand, the liquid of the mixed ester-based quaternary ammonium salt liquid raw material needs to be injected into the stirring tank 1 through the first feed pipe 101. It should be noted that the feed ports of the first feed pipe 101 and the second feed pipe 123 are both provided with electrically controlled liquid inlet one-way valves, and the electrically controlled liquid inlet one-way valve is a commonly used and well-known prior art by personnel in this field, and will not be described in detail here. By setting the electrically controlled liquid inlet one-way valve, the liquid raw material for preparing the ester-based quaternary ammonium salt and the liquid raw material of the mixed ester-based quaternary ammonium salt can be effectively prevented from flowing back, thereby causing a waste of raw materials.

[0048] At this time, the user can start the external motor connected to the connecting rod 103. As the external motor is started, the connecting rod 103 will perform a corresponding rotation effect inside the mixing tank 1 and on the top of the mixing tank 1.

[0049] When the connecting rod 103 rotates inside the mixing tank 1, since the inner core rod 113 is slidably arranged inside the connecting rod 103, and a connecting spring 125 is arranged between the inner core rod 113 and the connecting rod 103, through this arrangement, when the connecting rod 103 rotates, the inner core rod 113 will also rotate synchronously with the connecting rod 103;

[0050] See also Figure 6 It can be seen that, on the one hand, since the third connecting rod 115 is fixedly arranged on the blocking piece 134 through the connecting pipe 128, and the other end of the connecting pipe 128 is connected to the inside of the liquid storage pipe 127, and the blocking piece 134 is rotatably arranged inside the connecting annular groove 133, this arrangement can not only allow the liquid raw material for preparing the ester quaternary ammonium salt inside the liquid storage pipe 127 to flow into the liquid outlet cavity 121 through the connecting pipe 128, and then complete the corresponding mixing with the liquid of the mixed ester quaternary ammonium salt liquid raw material injected into the stirring tank 1, in this way, the effect of adding materials is achieved in the process of mixing the raw materials, and the injection position of the raw materials flowing out through the third connecting rod 115 is in a moving state, which effectively improves the mixing efficiency compared with the traditional fixed-point injection;

[0051] Moreover, when the third connecting rod 115 rotates, the connecting pipe 128 can also synchronously drive the blocking piece 134 to rotate accordingly, so as to avoid the liquid storage tube 127 being unable to supply liquid to the third connecting rod 115 when the third connecting rod 115 rotates. At the same time, the setting of the blocking piece 134 can also avoid the problem of liquid leakage on the inner wall of the liquid storage tube 127 to a certain extent.

[0052] On the other hand, one end of the third connecting rod 115 is provided on the inner core rod 113, and the third connecting rod 115 is provided on one end of the inner core rod 113 and is slidably arranged in an arc groove opened in the second arc-shaped movable groove 126 through a corresponding slider. Through the above arrangement, the third connecting rod 115 will only slide on the inner core rod 113 and will not be separated from the inner core rod 113. Therefore, when the inner core rod 113 synchronously follows the connecting rotating rod 103 to rotate, the third connecting rod 115 will also synchronously follow the inner core rod 113 to rotate, thereby completing the stirring effect of the liquid of the mixed ester quaternary ammonium salt liquid raw material that has been injected into the stirring tank 1 and the liquid raw material for preparing the ester quaternary ammonium salt.

[0053] Since a rotating base 104 is also provided on the top of the mixing tank 1, the rotating base 104 is slidably provided on the top surface of the mixing tank 1 through the first slider 112, and a plurality of first connecting teeth 105 are also provided on the outer surface of the rotating base 104;

[0054] On the other hand, the first connecting tooth opening 105 and the connecting rack 108 are meshed with each other, and one end of the connecting rack 108 is fixedly connected to the output end of the external hydraulic cylinder. Through this arrangement, the rotating base 104 can be temporarily fixed on the top surface of the mixing tank 1.

[0055] At the same time, two limiting ring plates 106 are arranged on the top surface of the rotating base 104, and a plurality of extrusion blocks 107 are arranged equidistantly inside the two limiting ring plates 106, and a second connecting rod 110 is arranged between two adjacent extrusion blocks 107, and the second connecting rod 110 is fixedly connected to the first connecting rod 109 ... Figure 3As can be seen, the first connecting rod 109 is also fixedly connected to the inner core rod 113. Therefore, when the connecting rotating rod 103 rotates, the connecting rotating rod 103 will synchronously drive the first connecting rod 109 and the second connecting rod 110 on the inner core rod 113 to rotate. When the second connecting rod 110 slides inside the limiting ring plate 106, the second connecting rod 110 will be resisted by the extrusion block 107, and then the inner core rod 113 fixedly connected on the first connecting rod 109 will be driven by the second connecting rod 110 to move upward accordingly inside the connecting rotating rod 103, and the connecting spring 125 will be stretched. When the second connecting rod 110 moves between the two extrusion blocks 107 (trough), the stretching reset force of the connecting spring 125 will drive the inner core rod 113 to move downward in the connecting rotating rod 103. By using the setting of multiple extrusion blocks 107, the inner core rod 113 can be driven to reciprocate up and down during the rotation of the connecting rotating rod 103.

[0056] Since a plurality of first arc-shaped moving grooves 118 are provided on the outer surface of the connecting rotating rod 103, and a second connecting tooth opening 119 is provided on one side surface of the first arc-shaped moving groove 118, and the second connecting tooth opening 119 is meshed with the connecting gear 120 sleeved on the surface of the third connecting rod 115, when the inner core rod 113 moves upward following the first connecting rod 109, a plurality of third connecting rods 115 provided on the inner core rod 113 will also move accordingly inside the corresponding first arc-shaped moving groove 118. By utilizing the setting of the first arc-shaped moving groove 118, a lateral movement is superimposed during the process in which the inner core rod 113 drives the third connecting rod 115 to move up and down, thereby further changing the raw material injection position of the third connecting rod 115, making the raw material injection position more dispersed, and facilitating the subsequent improvement of the mixing efficiency.

[0057] The movement of the third connecting rod 115 will also cause the connecting gear 120 arranged on the third connecting rod 115 to engage with the second connecting tooth mouth 119 arranged on one side of the first arc-shaped movable groove 118, thereby driving the third connecting rod 115 to perform a corresponding rotation effect during the movement. At the same time, since the third connecting rod 115 is also slidably arranged inside the second arc-shaped movable groove 126 opened in the inner core rod 113, even if the third connecting rod 115 moves upward, the opening of the second arc-shaped movable groove 126 will not cause the third connecting rod 115 to get stuck.

[0058] The above-mentioned arrangement not only allows the third connecting rod 115 to move up and down, thereby completing the layered stirring effect of the liquid of the mixed ester quaternary ammonium salt liquid raw material and the liquid raw material for preparing the ester quaternary ammonium salt, so as to improve the mixing efficiency of the two, but the third connecting rod 115 can also synchronously swing in the lateral direction during the up and down movement, thereby further improving the mixing effect of the liquid of the mixed ester quaternary ammonium salt liquid raw material and the liquid raw material for preparing the ester quaternary ammonium salt.

[0059] Since the third connecting rod 115 is also provided with a spiral groove 116, and one end of the second slider 117 is slidably arranged inside the spiral groove 116, and the other end of the second slider 117 is fixedly arranged on the liquid outlet pipe 114, and the liquid outlet pipe 114 is movably sleeved on the third connecting rod 115, when the third connecting rod 115 moves in the first arc-shaped moving groove 118, the connecting gear 120 on the third connecting rod 115 will mesh with the second connecting tooth opening 119, so that the third connecting rod 115 can rotate while moving in a circular arc in the first arc-shaped moving groove 118. At the same time, the first limiting rod 129 and the second limiting rod 132 on the liquid outlet pipe 114 are driven to make circular motion in the first limiting groove 130 and the second limiting groove 131 respectively. Due to the restriction of the ball at the end of the second limiting groove 131, the liquid outlet pipe 114 can only follow the third connecting rod 115 to make circular motion, and will not follow the rotation of the third connecting rod 115. Therefore, when the third connecting rod 115 rotates, the second slider 117 arranged on the inner wall of the third connecting rod 115 will slide in the spiral groove 116. Since the spiral groove 116 is spirally arranged, the liquid outlet pipe 114 drives the first limiting rod 129 and the second limiting rod 132 to translate to the right (see Figure 5 ), in this way, the raw material injection position is further changed, so that the raw material injection position is further dispersed;

[0060] At the same time, a connecting pipe 128 is provided at one end of the third connecting rod 115, and the connecting pipe 128 is rotatably arranged on the blocking piece 134, and the two are connected. The blocking piece 134 is arranged to block the connecting annular groove 133 provided on the liquid storage pipe 127, so as to effectively prevent liquid leakage, so that the material inside the liquid storage pipe 127 can flow into the liquid outlet cavity 121 inside the third connecting rod 115 through the connecting pipe 128, and when the third connecting rod 115 performs an arc motion, the blocking piece 134 can be driven to rotate in the connecting annular groove 133 through the connecting pipe 128, and when the third connecting rod 115 rotates, the connecting pipe 128 can be driven to rotate on the blocking piece 134, and the blocking piece 134 and the connecting pipe 128 can be arranged to allow the liquid to circulate normally while effectively preventing the situation of being stuck;

[0061] Through the above arrangement, not only can the liquid of the mixed ester quaternary ammonium salt liquid raw material and the liquid raw material for preparing the ester quaternary ammonium salt be better mixed, but also through the rotation of the connecting rod 103, on the one hand, the plurality of liquid outlet pipes 114 and the third connecting rod 115 can also effectively complete the stirring between the two, so as to effectively accelerate the mixing efficiency between the two;

[0062] On the other hand, by setting the first arc-shaped movable groove 118, the third connecting rod 115 can also rotate accordingly when following the inner core rod 113 to make reciprocating motion in the up and down directions, so that the liquid outlet pipe 114 can also move a certain distance. This setting also effectively changes the mixing point of the liquid raw material for preparing ester quaternary ammonium salt and the liquid of the mixed ester quaternary ammonium salt liquid raw material, thereby improving the mixing efficiency between the two. Moreover, changing the position of the liquid outlet pipe 114 also allows the liquid outlet pipe 114 to further improve the stirring range of the liquid raw material for preparing ester quaternary ammonium salt and the liquid of the mixed ester quaternary ammonium salt liquid raw material, thereby effectively improving the mixing efficiency between the two.

[0063] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. Figure 1-Figure 8 As shown, the connecting rack 108 is slidably arranged on the top surface of the mixing tank 1, the top end of the connecting rotating rod 103 is fixedly connected to the output end of the external motor, one end of the connecting rack 108 is fixedly connected to the output end of the hydraulic cylinder, and two limiting ring plates 106 are also arranged on the top of the rotating base 104.

[0064] In this embodiment: after a plurality of liquid outlet pipes 114 and the third connecting rod 115 mix and stir the liquid of the mixed ester quaternary ammonium salt liquid raw material and the liquid raw material for preparing the ester quaternary ammonium salt for a period of time, the user can start the external hydraulic cylinder arranged on the top surface of the stirring tank 1. Since a fixed connection is formed between the output end of the hydraulic cylinder and the connecting rack 108, the connecting rack 108 will move accordingly after the hydraulic cylinder is started. When the connecting rack 108 moves, the connecting rack 108 will drive the first slider 112 on the rotating base 104 to rotate on the stirring tank 1. By using the setting of the first slider 112, the rotation of the rotating base 104 is more stable. At the same time, the rotation of the rotating base 104 will change the position of the extrusion block 107 in the limiting ring plate 106, thereby simultaneously changing the two extrusion blocks 107. The position of the trough between the two extrusion blocks 107 is changed, and when the connecting rod 103 rotates again, the position of the rotating base 104 and the trough between the two extrusion blocks 107 are changed, so that the up and down reciprocating position of the inner core rod 113 inside the connecting rod 103 is offset, and the raw material injection point of the third connecting rod 115 is changed synchronously. Through such a setting, the raw material injection point position of the third connecting rod 115 when the rotating base 104 does not change the position of the extrusion block 107 and the raw material injection point position of the third connecting rod 115 when the position of the extrusion block 107 is changed are changed. By changing the position of the extrusion block 107, the highest point raw material injection position of the third connecting rod 115 is changed to the lowest point raw material injection position. In this way, the dispersion of raw material injection is further improved, and the mixing effect is improved.

[0065] When the liquid of the mixed ester quaternary ammonium salt liquid raw material inside the stirring tank 1 is thoroughly mixed with the liquid raw material for preparing the ester quaternary ammonium salt, the user can open the electrically controlled one-way valve connected to the discharge pipe 102, and then allow the mixed ester quaternary ammonium salt liquid to be discharged from the discharge pipe 102 outside the stirring tank 1, so as to complete the collection effect of the ester quaternary ammonium salt liquid.

[0066] In order to further better explain the above embodiment, the present invention also provides an embodiment, a method for preparing an ester group quaternary ammonium salt, comprising the following steps:

[0067] Step 1: Before preparing the ester quaternary ammonium salt, the liquid raw material for preparing the ester quaternary ammonium salt and the liquid of the mixed ester quaternary ammonium salt liquid raw material need to be injected into the stirring tank 1, and as the external motor is started, the third connecting rod 115 and the liquid outlet pipe 114 will rotate, thereby completing the mixing and stirring of the mixed liquid;

[0068] Step 2: a rotating base 104 is arranged on the top of the mixing tank 1, and a plurality of extrusion blocks 107 are arranged on the rotating base 104, so when the connecting rod 103 rotates, the extrusion blocks 107 will drive the second connecting rod 110 to move up and down intermittently;

[0069] Step 3: When the second connecting rod 110 moves up and down intermittently, the liquid outlet pipe 114 and the third connecting rod 115 can not only complete the layered stirring of the mixed liquid, but also move left and right, thereby increasing the stirring range of the liquid outlet pipe 114 and the third connecting rod 115, so as to effectively improve the stirring efficiency of the mixed liquid;

[0070] Step 4: When the mixed liquid inside the stirring tank 1 is thoroughly mixed, the user can discharge the mixed ester quaternary ammonium salt liquid from the discharge pipe 102 out of the stirring tank 1, thereby completing the corresponding collection.

[0071] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0072] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
