Description

Technical Field

[0001] The invention relates to the technical field of separation and defoaming devices, in particular to a cationic surfactant production device with a separation function. Background Art

[0002] Cationic surfactants are mainly nitrogen-containing organic amine derivatives, which can combine with hydrogen in acid molecules through hydrogen bonds to give the amino group a positive charge. They have good surface activity in acidic media, but are easily precipitated and lose their surface activity in alkaline media. During the production of cationic surfactants, the stock solution must first be filtered to remove impurities in the stock solution. However, during the filtration process, when the stock solution is poured and processed, a large number of bubbles will be stirred up inside the processing tank, affecting various operations. Therefore, after pouring the stock solution, a defoaming agent needs to be poured into the processing tank to reduce and avoid bubbles generated during the filtration of the stock solution.

[0003] However, as far as the currently available cationic surfactant production equipment is concerned, its defoaming agent cannot be added in a fixed proportion with the stock solution. Most of the time, the defoaming agent is poured in after the stock solution is poured in, resulting in uneven mixing of the stock solution and the defoaming agent, which reduces the defoaming effect. The defoaming effect is not obvious, affects various preparation and production operations of the surfactant, has poor flexibility, and is not practical. Summary of the invention

[0038] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention

[0039] Please refer to Figures 1 to 10 as shown in

[0040] Embodiment 1: The present invention provides a cationic surfactant production device with a separation function, including a processing component 1. The processing component 1 includes a processing tank 101 and a stirring motor 102. The stirring motor 102 is fixedly installed on the top of the processing tank 101, and a feed inlet 1011 and a discharge outlet 1012 are respectively provided at the top and bottom of the processing tank 101; it also includes a defoaming component and a connecting gear 4. The defoaming component is composed of a feeding mechanism 2 and an auxiliary mechanism 3

[0041] The feeding mechanism 2 includes a feeding base 201, a driving shaft 202 and a forward gear 203. The feeding base 201 is fixedly installed on the top of the processing tank 101, the driving shaft 202 is rotatably connected inside the feeding base 201, and the forward gear 203 is fixedly installed at the outer end of the driving shaft 202;

[0042] The auxiliary mechanism 3 includes a pumping base 301, a reverse gear 302, a reciprocating block 303, an adjusting rod 304 and a piston rod 305. The pumping base 301 is fixedly installed on the side of the feeding base 201, the reverse gear 302 is rotatably connected inside the pumping base 301, the reciprocating block 303 is inserted inside the pumping base 301, the adjusting rod 304 is rotatably connected inside the reciprocating block 303, and the piston rod 305 is inserted inside the pumping base 301;

[0043] The connecting gear 4 is rotatably connected inside the pumping base 301, and both sides of the connecting gear 4 are engaged and driven with the teeth of the forward gear 203 and the reverse gear 302 respectively.

[0044] In the embodiment of the present disclosure, a main feeding channel 2011 is provided inside the feeding base 201. The bottom end of the main feeding channel 2011 is connected to the feeding port 1011, and the main feeding channel 2011 is connected to the raw material feeding device through a pipeline. During use, the stock solution (raw material liquid) for the production of cationic surfactants can be injected into the processing tank 101 through the feeding mechanism 2. The raw material feeding device can inject the stock solution into the processing tank 101 through the main feeding channel 2011 and the feeding port 1011 through the pipeline for filtration and separation processing. The processed stock solution can be discharged through the discharge port 1012 for the next preparation and production operations. At the same time, under the action of the auxiliary mechanism 3, the defoaming agent can be continuously and quantitatively injected into the stock solution, so that while the stock solution is injected into the processing tank 101, the defoaming agent is mixed into the stock solution, improving the mixing effect of the stock solution and the defoaming agent as well as the defoaming effect, and making it flexible and convenient to use.

[0045] In the embodiment of the present disclosure, a driving blade 2021 is provided on the outside of one end of the driving shaft 202, and the axis of the driving shaft 202 deviates from the main feed channel 2011. In use, when the raw liquid passes through the main feed channel 2011, the liquid flow of the raw material will impact the driving blade 2021, thereby driving the driving shaft 202 to rotate, so that the driving shaft 202 can provide a driving effect for the auxiliary mechanism 3 when rotating, and realize the function of continuously and quantitatively injecting the defoaming agent into the interior of the raw liquid. The outside of the forward gear 203 and the counter gear 302 are both provided with a half-toothed ring 2031, and the side of the reciprocating block 303 is provided with two driving racks 3031. When the forward gear 203 and the counter gear 302 rotate, the two half-toothed rings 2031 can alternately engage with the gear teeth of the two driving racks 3031 for transmission. When the driving shaft 202 rotates, the forward gear 203 rotates synchronously. When the forward gear 203 rotates, it can drive the counter gear 3 through the connecting gear 4. The gear 302 rotates, and the forward gear 203 and the counter gear 302 rotate synchronously and in counter directions. Therefore, when the half-toothed ring 2031 of the forward gear 203 is transmitted with the driving rack 3031, the reciprocating block 303 moves downward, and when the half-toothed ring 2031 of the counter gear 302 is transmitted with the driving rack 3031, the reciprocating block 303 moves upward, thereby realizing a complete reciprocating movement of the reciprocating block 303. When the reciprocating block 303 moves downward, the upper positioning block 306 can drive the piston column 305 to move downward synchronously by contacting the driven shifting block 3051. When the reciprocating block 303 moves upward, the lower reset block 3032 can drive the piston column 305 to move upward by contacting the driven shifting block 3051, thereby realizing the function of extracting the defoaming agent and injecting it into the stock liquid through the reciprocating up and down movement of the piston column 305 inside the extraction chamber, and discharging it into the inside of the processing tank 101 together with the stock liquid. It is easy to use and mixes evenly.

[0046] In the embodiments of the present disclosure, a material extraction cavity is provided inside the material extraction seat 301, and the piston rod 305 is inserted into the material extraction cavity. The piston rod 305 divides the interior of the material extraction cavity into an upper cavity 3011 and a lower cavity 3012. Both the top and bottom of the material extraction cavity are provided with a suction channel 3013 and an injection channel 3014. One end of the suction channel 3013 is connected to the interior of the material extraction cavity, and the other end of the suction channel 3013 is connected to the bottom of the defoamer container through a pipeline. The two ends of the injection channel 3014 are respectively connected to the main feed channel 2011 and the material extraction cavity. During use, since the piston rod 305 divides the material extraction cavity into the upper cavity 3011 and the lower cavity 3012, under the combined action of the two cavities, the defoamer is continuously and uninterruptedly injected into the flowing stock solution, and there is no injection interval, further improving the mixing uniformity of the defoamer and the stock solution. When the piston rod 305 moves downward inside the material extraction cavity, at this time, the upper cavity 3011 can suck the defoamer through the suction channel 3013 at the top and store the defoamer temporarily inside the upper cavity 3011, and the lower cavity 3012 can inject the defoamer previously stored inside the cavity into the flowing stock solution through the injection channel 3014 at the bottom. When the piston rod 305 moves upward, the upper cavity 3011 can inject the defoamer into the flowing stock solution, while the lower cavity 3012 will suck the defoamer into the lower cavity 3012 for temporary storage, and the liquid injection is stable.

[0047] In the embodiments of the present disclosure, one-way valves 315 for controlling the flow direction are provided inside both the suction channel 3013 and the injection channel 3014. The one-way valves 315 can control the flow direction of the liquid inside the suction channel 3013 and the injection channel 3014, and the use is stable.

[0048] In the embodiment of the present disclosure, the auxiliary mechanism 3 further includes an upper positioning block 306, and the upper positioning block 306 is inserted into the reciprocating block 303. The upper positioning block 306 is located above the driven shifting block 3051. The outer surface of the rod body of the adjusting rod 304 is provided with threads, and the adjusting rod 304 is screwed into the upper positioning block 306 through the threads on the rod body. A driven shifting block 3051 is provided on the side surface of the piston column 305, and a lower reset block 3032 is provided on the side surface of the reciprocating block 303. When the piston column 305 is at the top dead center position, the lower reset block 3032 abuts against the bottom of the driven shifting block 3051. During use, since the maximum moving distance of the reciprocating block 303 is fixed, the maximum moving distance of the piston column 305 during reciprocating movement can be adjusted by adjusting the use position of the upper positioning block 306, that is, the injection amount of the defoaming agent per unit time is adjusted. When the adjusting rod 304 rotates, the adjusting rod 304 can drive the upper positioning block 306 to move and change the use position through the threads on the rod body. Since the maximum moving distance of the reciprocating block 303 is fixed, after the upper positioning block 306 changes the use position, the abutting timing between the upper positioning block 306 and the driven shifting block 3051 when the reciprocating block 303 moves downward is changed, that is, the maximum downward movement distance that the reciprocating block 303 can drive the piston column 305 is changed. At the same time, since the lower reset block 3032 always abuts against the bottom of the driven shifting block 3051 when the piston column 305 is at the top dead center position, the reciprocating block 303 can always drive the piston column 305 to move upward and reset by abutting against the driven shifting block 3051 through the lower reset block 3032 when moving upward. Therefore, by changing the use position of the upper positioning block 306, the maximum reciprocating moving distance of the piston column 305, that is, the injection amount of the defoaming agent per unit time, can be changed, which can adapt to the production and use of different types of active agents and has extremely strong adaptability.

[0049] Specific usage and function of this embodiment: In the present invention, the stock solution (raw liquid) for the production of the cationic surfactant can be injected into the interior of the processing tank 101 through the feeding mechanism 2, and the raw liquid supply device can inject the stock solution into the interior of the processing tank 101 through the main feeding channel 2011 and the feeding port 1011 through the pipeline for filtering and separation treatment. The stock solution after treatment can be discharged through the discharge port 1012 to carry out the next preparation and production operation. At the same time, under the action of the auxiliary mechanism 3, the defoaming agent can be continuously and quantitatively injected into the interior of the stock solution, so that when the stock solution is injected into the interior of the processing tank 101, the defoaming agent is mixed in the interior of the stock solution, thereby improving the mixing effect of the stock solution and the defoaming agent and the defoaming effect. When the stock liquid passes through the main feed channel 2011, the liquid flow of the raw material will impact the driving blade 2021, thereby driving the driving shaft 202 to rotate, so that the driving shaft 202 can provide a driving effect for the auxiliary mechanism 3 when rotating, so as to realize the function of continuously and quantitatively injecting the defoaming agent into the interior of the stock liquid. When the driving shaft 202 rotates, the forward gear 203 rotates synchronously, and the forward gear 203 can drive the counter-rotating gear 302 to rotate through the connecting gear 4 when rotating, and the forward gear 203 and the counter-rotating gear 302 rotate synchronously and in opposite directions, so that when the half-toothed ring 2031 of the forward gear 203 and the driving rack 3031 are in transmission, the reciprocating block 303 moves downward, and when the half-toothed ring 2031 of the counter-rotating gear 302 and the driving rack 3 When the reciprocating block 303 is in transmission, the reciprocating block 303 moves upward, thereby realizing a complete reciprocating movement of the reciprocating block 303. When the reciprocating block 303 moves downward, the upper positioning block 306 can drive the piston column 305 to move downward synchronously by means of the resistance to the driven shifting block 3051. When the reciprocating block 303 moves upward, the lower reset block 3032 can drive the piston column 305 to move upward by means of the resistance to the driven shifting block 3051. Thus, the piston column 305 can reciprocate up and down in the extraction chamber to realize the function of extracting the defoaming agent and injecting it into the stock liquid, and then discharge it into the processing tank 101 together with the stock liquid. Since the piston column 305 divides the extraction chamber into the upper chamber 3011 and the lower chamber 3012, the defoaming agent can be removed by the cooperation of the two chambers. The defoaming agent is continuously and uninterruptedly injected into the flowing stock solution without any injection interval, which further improves the mixing uniformity of the defoaming agent and the stock solution. When the piston rod 305 moves downward inside the extraction chamber, the upper chamber 3011 can extract the defoaming agent through the suction channel 3013 at the top and temporarily store the defoaming agent inside the upper chamber 3011, and the lower chamber 3012 can inject the defoaming agent originally temporarily stored inside the chamber into the flowing stock solution through the injection channel 3014 at the bottom. When the piston rod 305 moves upward, the upper chamber 3011 can inject the defoaming agent into the flowing stock solution, and the lower chamber 3012 will extract the defoaming agent to the lower chamber 3012 for temporary storage. Since the maximum moving distance of the reciprocating block 303 is fixed,Thus, by adjusting the use position of the upper positioning block 306, the maximum moving distance of the piston column 305 during reciprocating movement can be adjusted, that is, the injection amount of the defoaming agent per unit time is adjusted. When the adjusting rod 304 rotates, the adjusting rod 304 can drive the upper positioning block 306 to move and change the use position through the rod body thread. Since the maximum moving distance of the reciprocating block 303 is fixed, after the upper positioning block 306 changes the use position, that is, the contact timing between the upper positioning block 306 and the driven dial block 3051 when the reciprocating block 303 moves downward is changed, that is, the maximum downward moving distance that the reciprocating block 303 can drive the piston column 305 is changed. At the same time, since the lower reset block 3032 always contacts the bottom of the driven dial block 3051 when the piston column 305 is at the top dead center position, the reciprocating block 303 can always drive the piston column 305 to move upward and reset by contacting the driven dial block 3051 through the lower reset block 3032 when moving upward. Thus, by changing the use position of the upper positioning block 306, the maximum reciprocating moving distance of the piston column 305, that is, the injection amount of the defoaming agent per unit time, can be changed, and it can adapt to the production and use of different types of surfactants.
