DETAILED DESCRIPTION

[0025] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Reference Figures 1 to 7 The present invention provides a technical solution: a fatty alcohol fatty acid ester preparation device, comprising a tank body 1, a plurality of support legs 9 are provided at the bottom edge of the tank body 1, the support legs 9 are supported on the ground or fixed on the ground, a valve 10 is provided at the bottom of the tank body 1, the valve 10 is arranged at the center of the bottom of the tank body, and is used to discharge the fatty alcohol fatty acid ester in the tank body, the valve 10 can be electrically controlled or manually controlled, a top cover 12 is detachably provided at the top of the tank body 1, and the edge of the top cover 12 is fastened to the top edge of the tank body 1 by bolts or locks. At the same time, a feeding port 8 is provided at the top edge of the top cover 12, and the feeding port 8 is used to add reactants into the tank body, and a sealing cover is detachably provided at the top of the feeding port 8, and the edge of the sealing cover is specifically connected to the feeding port 8 by a lock.

[0027] like Figure 7As shown, a stirring shaft 5 is coaxially arranged in the tank body 1, the top of the stirring shaft 5 is rotatably connected to the center of the top cover 12, and a paddle 21 is arranged at the bottom of the stirring shaft 5. Figure 7 As shown, the stirring shaft 5 extends to the bottom of the tank body 1, and the paddle 21 is coaxially arranged in the annular cover 16, so the annular cover 16 is also located at the bottom of the tank body 1, and a certain distance is set between the bottom of the annular cover 16 and the bottom of the tank body 1, and the bottom of the annular cover 16 is connected to the bottom of the tank body 1 through a plurality of supports 15, and the annular cover 16 is connected to the tank body 1 through the provided supports 15. At the same time, due to the support of the supports 15, there is a distance between the annular cover 16 and the tank body 1;

[0028] like Figure 4 and Figure 6 As shown, a spinner 4 is also provided above the annular cover 16, and the spinner 4 is coaxially mounted on the stirring shaft 5. A driving device is provided on the side of the tank body 1, and the top of the stirring shaft 5 is driven to rotate by the driving device;

[0029] It should be noted that the annular cover 16 in the present application is equivalent to the pump housing, and the paddle 21 is equivalent to the impeller or fan placed in the pump housing, and the distance between the bottom of the annular cover 16 and the bottom of the tank body 1 is equivalent to the inlet, so when the paddle 21 rotates, it can drive the reactants to move toward the inside of the annular cover 16, allowing the reactants to enter the annular cover 16 and then quickly flow out from the top of the annular cover 16. Due to the cooperation between the annular cover 16 and the paddle 21, the two form a pump body mechanism, which can allow the reactants to quickly enter from the bottom of the annular cover 16 and then quickly flow out from the top thereof;

[0030] The top of the annular cover 16 is coaxially provided with a tightening port 14, so that the outlet of the annular cover 16 can be contracted, which can increase the pressure inside the annular cover 16 and make the reactants flow out of the tightening port 14 faster. Figure 7 As shown, the reactants flowing out of the tightening port 14 flow upward rapidly and hit the bottom of the spinning plate 4, as shown in FIG. Figure 4 As shown, a plurality of arc plates 11 are provided at the bottom edge of the spinning tray 4, and the arc plates 11 are evenly spaced at the edge of the spinning tray 4, so that the rotating spinning tray 4 can throw the reactants that collide with it toward the edge of the spinning tray 4, allowing the thrown reactants to flow to both sides. This process is reciprocating, so the reactants in the tank body can be fully mixed.

[0031] Further, the top of the stirring shaft 5 is movably placed in the support tube body 6 and the two are rotatably connected. The top of the support tube body 6 is placed in the support sleeve 7 and the two are rotatably connected. The support sleeve 7 is coaxially fixed to the middle of the top cover 12. The support sleeve 7 and the top cover 12 are integrated here. The support sleeve 7 mainly plays a supporting role. It is specifically connected to the support tube body 6 through a bearing, and the support tube body 6 is also connected to the stirring shaft 5 through a bearing. The stirring shaft 5 is equivalent to an inner shaft, and the support tube body 6 is equivalent to an outer shaft. Figure 7As shown, the support tube body 6 extends into the top cover 12 or slightly below the top cover 12, so that the bottom of the support tube body 6 is at a certain distance from the reactant page, so as to avoid the rotation connection between the support tube body 6 and the stirring shaft 5 being immersed in the reactant;

[0032] Next, the bottom of the support tube 6 extends into the tank 1, and a plurality of stirring mechanisms are arranged on the side of the lower end of the support tube 6, and the stirring mechanisms are distributed around the annular cover 16. Figure 4 and Figure 5 As shown, the stirring mechanism includes a plurality of support rods 20 mounted on the side of the lower end of the support tube 6, and the bottom of the support rods 20 is located around the annular cover 16. A plurality of second stirring blades 18 are provided on the side of each support rod 20 close to the annular cover 16, and a plurality of first stirring blades 19 are provided on the side of each support rod 20 away from the annular cover 16, and the second stirring blades 18 and the first stirring blades 19 are inclined and the inclination directions of the two are opposite. Figure 4 and Figure 6 As shown, the top of the support rod 20 is bent in an "L" shape to prevent the support rod 20 from contacting the annular cover 16;

[0033] It should be emphasized that the top of the support tube 6 is driven to rotate by a driving device, that is, the support tube 6 and the stirring shaft 5 are simultaneously connected to a driving device. Figure 1 and Figure 4 As shown, the driving device includes a driving motor 2 arranged on the side of the tank body 1, the rotating shaft of the driving motor 2 extends above the tank body 1, two pulleys are installed on the top of the rotating shaft, and pulleys are respectively provided on the top of the stirring shaft 5 and the top of the supporting tube body 6, and the pulleys are connected by belts;

[0034] In order to allow the blades 21 to quickly discharge the reactants from the annular cover 16, the rotation speed of the stirring shaft 5 is faster than the rotation speed of the supporting tube body 6. This process can achieve different transmission ratios by setting the size of the pulley, that is, a large reel with a reel is formed between the driving motor 2 and the stirring shaft 5, so that the rotation speed of the stirring shaft 5 is significantly accelerated, and a small reel with a large reel is formed between the driving motor 2 and the supporting tube body 6, so that the rotation speed of the supporting tube body 6 is significantly reduced;

[0035] Specifically, Figure 4 As shown, when the spinning disc 4 throws the reactants around, the thrown reactants collide with the second stirring blade 18 and the first stirring blade 19. The second stirring blade 18 and the first stirring blade 19 can fully stir the reactants, so that the reactants in the tank body 1 can be mixed at a faster speed.

[0036] Furthermore, the bottom of the tank body 1 is a conical structure, and a strip blade 17 tangent to the surface of the conical structure is installed at the bottom of each support rod 20, and the strip blade 17 is distributed outside the space surrounded by the support 15. The provided strip blade 17 can not only scoop up the reactants at the bottom of the tank body 1, but also progressively move the scooped reactants toward the annular cover 16, so that the reactants can flow into the annular cover 16 more smoothly.

[0037] Based on the above embodiment, further optimization can be performed, such as Figure 5 As shown, the bottom of the support sleeve 7 extends to below the top cover 12. Because the support sleeve supports the inner shaft and the outer shaft, in order to enhance the supporting strength of the support sleeve 7, a plurality of triangular reinforcement seats are provided between the bottom side of the support sleeve 7 and the top cover 12.

[0038] Based on the above embodiment, further optimization can be performed, such as Figure 2 and Figure 3 As shown, a protective cover 13 is provided on the top of the tank body 1. The protective cover 13 is "L"-shaped. The protective cover 13 is clamped on the stirring shaft 5 and the driving motor 2. The protective cover 13 is connected to the top cover 12 and the side of the tank body 1 respectively.

[0039] Based on the above embodiment, further optimization can be performed. In order to better support the shaft of the driving motor 2, the top of the shaft is rotatably installed in the support arm 3, and the other end of the support arm 3 is connected to the top cover 12 or the tank body 1.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
