Description

Technical Field

[0001] The utility model relates to the field of polyglutamic acid preparation, and more specifically, it relates to a mixing device based on polyglutamic acid preparation. Background Art

[0002] Polyglutamic acid, also known as natto gum and polyglutamic acid, is a homogeneous polypeptide formed by polymerizing L- and D-glutamic acid monomers through amide bonds at the γ-position, with a degree of polymerization of about 1000 - 15000. It is a biodegradable and non-toxic polymer prepared by microbial fermentation. In the field of cosmetics, it has functions such as moisturizing, whitening, firming and anti-aging. Its moisturizing ability far exceeds that of hyaluronic acid. It can inhibit melanin production, promote nutrient absorption, and can also be used in hair care products.

[0003] In the process of polyglutamic acid preparation, material mixing is one of the key links. First, the required raw materials are put into the mixing equipment in a certain proportion. During the mixing process, different materials are fully contacted and evenly dispersed by means of stirring, etc. However, in the prior art, in order to enable the stirring paddle to move its position to increase the stirring range (such as a polyglutamic acid purification and preparation device disclosed in the publication number CN210945447U), generally two motors need to be set (one motor drives the stirring paddle to rotate self for stirring, and one motor drives the movement of the stirring paddle). This undoubtedly increases the cost, and at the same time, the power supply problem of the extra motor needs to be considered. Moreover, the raw materials that need to be dissolved in water during the polyglutamic acid preparation process are usually added at fixed positions (for example, materials such as glucose, yeast powder, and magnesium sulfate need to be dissolved in water), which is likely to result in uneven distribution, causing the stirring paddle to need to stir for a long time to promote its diffusion and mixing in water.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a mixing device based on polyglutamic acid preparation. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the present utility model is to provide a mixing device based on polyglutamic acid preparation.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: A mixing device based on polyglutamic acid preparation, including a mixing tank and a top cover installed on the top of the mixing tank, characterized in that: a motor is installed on the inner top wall of the top cover, and the mixing device based on polyglutamic acid preparation further includes:

[0007] A transmission mechanism, which is installed on the outer side wall of the top cover and is used to connect the stirring paddle and the motor. Through the transmission of the transmission mechanism, the motor can not only drive the stirring paddle to rotate around the motor transmission shaft as the center of the circle, but also enable the stirring paddle to rotate self to achieve the stirring effect;

[0008] The central rod inside the stirring paddle is hollow, and a plurality of through holes are formed on its outer side wall.

[0009] Preferably, the transmission mechanism includes a planetary gear on the outer side wall of the fixed top cover and a connecting plate fixed on the motor transmission shaft. The bottom of the connecting plate is rotatably connected with an internal gear through a bearing. The outer side wall of the internal gear is meshed and connected with the inner side wall of the planetary gear. The stirring paddle is installed at the bottom of the internal gear.

[0010] Preferably, the stirring paddle is detachably connected to the internal gear, and the stirring paddle can be detached for cleaning.

[0011] Preferably, the bottom end of the internal gear is fixedly connected with a mounting post, and a threaded groove is formed at the bottom. The top of the central rod of the stirring paddle is open, and a thread corresponding to the threaded groove is formed on the outer side wall of the top.

[0012] Preferably, the bottom end of the mixing tank is fixedly connected with a base. An electric hydraulic rod is fixedly installed beside the mixing tank at the top end of the base. The head of the electric hydraulic rod is fixed to the outer side wall of the top cover through a cross plate, which is convenient for adding materials and water into the mixing tank and adding materials into the central rod.

[0013] Preferably, an observation window for observing the internal materials is installed on the surface of the mixing tank to visually observe the mixing state of the materials in the tank.

[0014] Preferably, a discharge pipe is installed at a position close to the bottom of the outer side wall of the mixing tank, and a discharge valve is installed on the discharge pipe. The mixed materials are discharged through the discharge pipe.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. Through the transmission of the transmission mechanism by the motor of the utility model, the stirring paddle can not only be driven to rotate around the motor transmission shaft as the center of the circle, but also the stirring paddle can rotate itself to achieve the stirring effect, so as to increase the stirring range, make the stirring more comprehensive, and improve the mixing effect. In this way, one motor can realize the movement and self-rotation of the stirring paddle, which not only reduces the cost, but also does not need to consider the power supply problem of redundant motors, thus solving the problem in the background technology that in order to make the stirring paddle move to increase the stirring range, the cost is undoubtedly increased;

[0017] 2. The utility model can put some of the materials that need to be dissolved in water in the production of polyglutamic acid into the central rod. When the stirring paddle moves and rotates itself, the materials in the central rod will contact the water in different areas of the mixing tank through the through holes, which is more conducive to their diffusion and mixing, thus improving the stirring efficiency;

[0018] 3. An observation window for observing the internal materials is installed on the surface of the mixing tank of the present utility model, so as to visually observe the mixing state of the materials in the tank, such as the fluidity and uniformity of the materials, etc., in order to adjust the stirring speed in time;

[0019] 4. The stirring paddle and the internal gear of the present utility model are detachably connected, so that the stirring paddle can be disassembled for cleaning, which is convenient for the staff to carry out cleaning operations;

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] As Figures 1-4 shown, the present utility model provides a mixing device based on the preparation of polyglutamic acid, including a mixing tank 1, and a top cover 2 installed on the top of the mixing tank 1. A motor 3 is installed on the inner top wall of the top cover 2. A discharge pipe 13 is installed on the outer side wall of the mixing tank 1 near the bottom, and a discharge valve 14 is installed on the discharge pipe 13. The mixing device based on the preparation of polyglutamic acid further includes:

[0028] The transmission mechanism 4 is installed on the outer side wall of the top cover 2 and is used to connect the stirring paddle 5 and the motor 3. Through the transmission of the transmission mechanism 4, the motor 3 can drive the stirring paddle 5 to rotate around the axis of the motor 3 transmission shaft and can also make the stirring paddle 5 rotate self - sufficiently to achieve the stirring function.

[0029] The central rod 501 of the stirring paddle 5 is hollow inside, and a plurality of through - holes 6 are arranged on its outer side wall.

[0030] During use, some of the materials that need to be dissolved in water during the production of polyglutamic acid can be put into the central rod 501. It should be noted that the aperture of the through - holes 6 on the central rod 501 is relatively small. When this part of the material is not dissolved, it is difficult to break away from the central rod 501. Then, put other materials and water into the mixing tank 1, install the top cover 2 on the top of the mixing tank 1, and then turn on the motor 3. Through the transmission of the transmission mechanism 4, the motor 3 can drive the stirring paddle 5 to rotate around the axis of the motor 3 transmission shaft and can also make the stirring paddle 5 rotate self - sufficiently to achieve the stirring function, so as to increase the stirring range, make the stirring more comprehensive, and improve the mixing effect. In this way, one motor 3 can realize the movement and self - rotation of the stirring paddle 5, which not only reduces the cost, but also does not need to consider the power supply problem of the redundant motor 3. Moreover, when the stirring paddle 5 moves and rotates self - sufficiently, the materials in the central rod 501 will contact the water in different areas of the mixing tank 1 through the through - holes 6, which is more conducive to their diffusion and mixing, thereby improving the stirring efficiency. Finally, after the stirring and mixing are completed, open the discharge valve 14 to discharge the stirred materials inside the mixing tank 1 through the discharge pipe 13.

[0031] The bottom end of the mixing tank 1 is fixedly connected with a base 9. A motor - driven hydraulic rod 10 is fixedly installed beside the mixing tank 1 at the top end of the base 9. The head of the motor - driven hydraulic rod 10 is fixed to the outer side wall of the top cover 2 through a cross - plate 11. The lifting of the cross - plate 11 can be driven by the motor - driven hydraulic rod 10, and the up - and - down movement of the top cover 2 can be driven by the cross - plate 11, so as to realize the extension and insertion of the stirring paddle 5 from the mixing tank 1 and the opening and closing of the mixing tank 1, which is convenient for adding materials and water into the mixing tank 1 and adding materials into the central rod 501. An observation window 12 for observing the internal materials is installed on the surface of the mixing tank 1 to visually observe the mixing state of the materials inside the tank, such as the fluidity and uniformity of the materials, so as to adjust the stirring speed in time.

[0032] The following is the specific structure of the transmission mechanism 4: The transmission mechanism 4 includes a planetary gear 401 fixed on the outer side wall of the top cover 2 and a connecting plate 402 fixed on the transmission shaft of the motor 3. The bottom of the connecting plate 402 is rotatably connected with an internal gear 404 through a bearing 403. The outer side wall of the internal gear 404 is meshed with the inner side wall of the planetary gear 401, and the stirring paddle 5 is installed at the bottom of the internal gear 404.

[0033] When the motor 3 is running, the motor 3 drives the rotation of the connecting plate 402, and the connecting plate 402 drives the rotation of the internal gear 404, so that the internal gear 404 rotates around the transmission shaft of the motor 3 as the center. At the same time, the internal gear 404 is also driven by the planetary gear 401 to rotate on its own axis (since the connecting plate 402 and the internal gear 404 are rotationally connected through the bearing 403, so it can be driven by the planetary gear 401 to rotate on its own axis), thereby driving the stirring paddle 5 to rotate and move while rotating on its own axis for stirring.

[0034] Furthermore, the stirring paddle 5 and the internal gear 404 are detachably connected, so that the stirring paddle 5 can be detached for cleaning, which is convenient for the staff to carry out cleaning operations. The following is the specific detachable structure: a mounting post 7 is fixedly connected to the bottom end of the internal gear 404, and a threaded groove 8 is opened at the bottom. The top of the central rod 501 of the stirring paddle 5 is open, and a thread corresponding to the threaded groove 8 is provided on the outer side wall of the top. That is, first add a part of the material dissolved in water into the central rod 501 through the opening at the top of the central rod 501. After adding is completed, rotate the central rod 501 clockwise to rotate the top of the central rod 501 into the threaded groove 8, and the central rod 501 can be fixed to the mounting post 7, thereby fixing the stirring paddle 5 to the internal gear 404. On the contrary, rotate the central rod 501 counterclockwise, and the central rod 501 can be taken out of the threaded groove 8 to realize the disassembly between the stirring paddle 5 and the internal gear 404.

[0035] The above is only the preferred embodiment of the present invention, and it is not intended to limit the present invention in any form; any ordinary technician in the industry can smoothly implement the present invention as shown in the accompanying drawings of the specification and the above description; however, any slight changes, modifications and equivalent changes made by those skilled in the art within the scope of the technical solution of the present invention by using the technical content disclosed above are all equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essence of the present invention still fall within the protection scope of the technical solution of the present invention.
