Description

Technical Field

[0001] This utility model relates to the field of p-methoxybenzaldehyde production technology, specifically a stirring device for the green catalytic synthesis of p-methoxybenzaldehyde. Background Technology

[0002] p-Methoxybenzaldehyde (PMBA), also known as p-methoxybenzaldehyde or anisaldehyde, is an important fine chemical with the molecular formula C8H8O2. At room temperature, it is a colorless or pale yellow oily liquid with a persistent hawthorn aroma. It has a wide range of applications, including the development of high-value-added downstream products such as raspberry ketone; the formulation of daily-use fragrances and food flavorings, such as the main flavoring in hawthorn flower, sunflower, and lilac fragrances, and as a modifier in lily of the valley and osmanthus fragrances; an important intermediate in organic synthesis, it is an intermediate in the preparation of the antimicrobial drug hydroxycaproic acid, and also an intermediate in the synthesis of porphyrin photosensitizers; it can also be used as a fluorescent probe for the determination of biomolecules such as nucleic acids.

[0003] Currently, the preparation of p-methoxybenzaldehyde (PMBA) requires stirring and mixing the raw materials to ensure thorough mixing and catalytic reaction. A search revealed a chemical synthesis material stirring device in Chinese patent application number 202420996326.3, which relates to the field of material stirring devices. This invention includes a frame, a first motor at the top of the barrel, a stirring rod at the output of the first motor, a lifting device on one side of the frame, a rectangular plate with a groove block fixedly connected to one side of the rectangular plate, a rectangular groove on one side of the outer surface of the frame, a second motor at the top of the frame, and a screw threadedly connected to the inner wall of the groove block. A positioning rod is fixedly connected to one side of the frame. This invention, by incorporating the lifting device, allows the chemical container to be placed above the rectangular plate during stirring. The second motor drives the screw to rotate, adjusting the height of the rectangular plate to the top of the barrel, facilitating the pouring of the chemical material from the container into the barrel, thus increasing the convenience and practicality of using the stirring device.

[0004] In the above technical solution, the container storing the raw materials is transported to a high place by a lifting device and then poured into a mixing tank for mixing. However, neither the rectangular plate and the auxiliary plate, which serve as the support platform for the container, have the function of limiting and fixing the container. During the operation and lifting process of this equipment, the machine body will shake, which may easily cause the container to tip over or fall, making it inconvenient to use and posing a significant safety hazard. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a stirring device for the green catalytic synthesis of p-methoxybenzaldehyde. This device solves the problems of the lack of effective limiting and fixing of the container, which causes shaking during the lifting process, easily leading to the container tipping over or falling, making it inconvenient to use and posing significant safety hazards.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0009] A stirring device for the green catalytic synthesis of p-methoxybenzaldehyde includes a placement plate and a limiting frame. The placement plate is threadedly connected to a lead screw on a frame via a threaded sleeve. The lead screw is driven by a drive motor. Sliding rods on both sides of the lead screw are slidably connected to the sliding sleeves on the placement plate. A stirring tank is placed on the frame and fixedly connected to the frame via a bracket. A connecting shaft is provided on the support rod of the limiting frame. The connecting shaft is rotatably connected to a connecting lug on the placement plate via a rotating shaft. A mounting frame is provided at the lower end of the support rod, and an abutment frame is provided at the upper end.

[0010] Furthermore, the placement plate is provided with a semi-circular placement area for accommodating the limiting frame, and a slot for rotating the support rod is provided at the position of the connecting ear plate on the placement plate.

[0011] Furthermore, the connecting section formed by bending the lower end of the support rod is fixedly connected to the scaffolding, and the connecting section formed by bending the upper end of the scaffolding is fixedly connected to the contact frame. Both ends of the contact frame are integrally bent to form arc-shaped ends, and a rubber strip is placed on the contact frame between the two arc-shaped ends.

[0012] The rubber strip has a deformation cavity, and a connecting strip integrally set on one side of the rubber strip is fixedly attached to the contact frame, and the curvature of the rubber strip matches the curvature of the contact frame.

[0013] The limiting block at the end of the connecting shaft on one side of the support rod is initially placed on the placement plate, and an elastic spring plate is installed between the support rod at the bottom of the connecting shaft and the placement plate.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a stirring device for the green catalytic synthesis of p-methoxybenzaldehyde, which has the following beneficial effects:

[0016] This invention involves installing limiting and fixing components on the placement plate of a lifting container. Two adjacent limiting frames effectively clamp and fix the container. The container's own weight causes the upper end of the support rod to firmly clamp the container's side wall. The bottom of the container is limited by a placement frame, thus stably placing it on the placement frame. This ensures the container's stability during lifting, steadily raising it to the designated position, eliminating the safety hazard of tipping or falling, and guaranteeing stable use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in one embodiment of this utility model, a stirring device for the green catalytic synthesis of p-methoxybenzaldehyde includes a placement plate 1 and a limiting frame 2. The placement plate 1 is threadedly connected to a lead screw 3 on a frame 5 via a threaded sleeve 102. The lead screw 3 is connected to a drive motor 6 for easy operation. The lead screw 3 drives the placement plate 1 to move on the frame 5, thereby moving a container holding materials to a designated height and adding the materials to a mixing tank 7 for mixing. Sliding rods 4 on both sides of the lead screw 3 are slidably connected to the sliding sleeve 103 on the placement plate 1, improving the stability of the placement plate 1 sliding on the frame 5 and ensuring stable use. The mixing tank 7 is mounted on the frame 5 and is fixedly connected to the frame 5 via a bracket 8. The frame 5 facilitates the stable installation of the mixing tank 7 on the frame 5. The mixing tank 7 and its built-in mixing mechanism are used to mix the materials. The built-in mixing mechanism and the mixing tank 7 are existing known and publicly available technologies, which will not be described in detail. The support rod 201 of the limiting frame 2 is provided with a connecting shaft 203. The connecting shaft 203 is rotatably connected to the connecting ear plate 101 on the placement plate 1 through a rotating shaft 204. The lower end of the support rod 201 is provided with a mounting frame 202 and the upper end is provided with an abutment frame 207. The limiting frame 2 forms a clamping component on the placement plate 1 to limit and fix the container, so that the container can be placed stably and prevented from tipping over or falling during movement, thus ensuring stable use.

[0026] like Figure 2 and Figure 3 As shown, in some embodiments, the placement plate 1 is provided with a semi-circular placement area for placing the limiting frame 2, which is used to place the limiting frame 2 and temporarily place the container, thereby limiting and fixing the placed container to prevent it from tipping over or falling during the upward movement, ensuring stable use. The connecting ear plate 101 on the placement plate 1 is provided with a slot for the support rod 201 to rotate, so that the support rod 201 can rotate on the placement plate 1, thereby clamping and fixing the container, avoiding movement interference, and ensuring smooth use.

[0027] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the lower end of the support rod 201 is bent to form a connecting section that is fixedly connected to the scaffold 202, and the upper end of the scaffold 202 is bent to form a connecting section that is fixedly connected to the contact frame 207. This facilitates the stable connection of the three together, allowing them to work together stably and securely to limit and fix the container. Both ends of the contact frame 207 are integrally bent to form arc-shaped ends 208, which facilitates the smooth placement of the container between two adjacent contact frames 207, improving ease of use and ensuring smooth operation. Furthermore, a rubber strip 209 is installed on the contact frame 207 between the two arc-shaped ends 208 to facilitate soft contact and reduce wear.

[0028] The rubber strip 209 has a deformation cavity 2092, which facilitates appropriate deformation during contact with the container, buffering the force applied by the contact frame 207 to the outer wall of the container and reducing wear between the two. The connecting strip 2091 integrally provided on one side of the rubber strip 209 is fixedly attached to the contact frame 207, and the curvature of the rubber strip 209 matches the curvature of the contact frame 207. The connecting strip 2091 is used to stably install the rubber strip 209 onto the contact frame 207, thereby forming a soft contact part on the contact frame 207, which reduces the wear of the contact frame 207 on the container and ensures stable use.

[0029] The limiting block 205 at the end of the connecting shaft 203 on one side of the support rod 201 initially rests on the placement plate 1, ensuring that the abutment frame 207 at the upper end of the support rod 201 does not abut together in the initial state, so that the two are kept at a set distance, making it convenient to place the container between two adjacent limiting frames 2 for stable use. In addition, an elastic spring plate 206 is installed between the support rod 201 at the lower part of the connecting shaft 203 and the placement plate 1, so that the support rod 201 can generate appropriate deformation during the rotation of the support rod 201. When the external stress loses its downward pressure on the placement frame 202, the elastic spring plate 206 drives the support rod 201 to rotate and reset on the connecting ear plate 101 for subsequent stable use.

[0030] During use, the container holding the material is placed between the two limiting frames 2 on the placement plate 1, with the bottom of the container resting on the support frame 202 at the lower end of the support rod 201. Then, the drive motor 6 is started, and the placement plate 1 is moved on the frame 5 via the lead screw 3. As the placement plate 1 moves upward with the limiting frames 2, the container exerts a downward force on the support frame 202 under the action of gravity. Subsequently, the support frame 202 will rotate on the connecting ear plate 101 with the support rod 201. At the same time, during the rotation, the support rod 201 will move the upper contact frame 207 towards the outer wall of the container until it is tightly against the outer wall of the container. Then, in conjunction with the lower support frame 202, the container is firmly fixed on the placement plate 1. Then, it is moved to the designated height, and the material in the container is poured into the mixing tank 7. The mixing tank 7 is then turned on to mix the material.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
