Technical Field
[0001] This utility model belongs to the field of benzoic acid raw material mixing technology, specifically a mixing device for processing benzoic acid raw materials. Background Technology
[0002] Benzoic acid is an aromatic acid organic compound, and also the simplest aromatic acid. It was originally obtained from benzoin gum, hence the name benzoic acid. It has a slight odor of benzaldehyde or benzoin. At room temperature of about 25°C, its PKa value is 4.2. It is a monoprotic weak acid, but its acidity is stronger than that of fatty acids. It has a stable chemical structure and is not easily oxidized.
[0003] When mixing benzoic acid raw materials, the stirring shaft angle inside the mixing device in the existing technology is fixed. This leads to excessive stirring torque and increased energy consumption when dealing with high viscosity mixtures such as molten benzoic acid. At the same time, when dealing with different formulations, such as solid-solid mixing and solid-liquid suspension, equipment problems are required. Utility Model Content
[0004] To address the problems mentioned in the background section, this invention provides a mixing device for processing benzoic acid raw materials, which has the advantage of adjustable stirring shaft angle. This invention solves the problem that mixing devices cannot adjust the stirring shaft; by adjusting the stirring shaft angle, it can adapt to mixing different formulations and use raw materials in various states, while also reducing energy consumption and protecting equipment safety.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for processing benzoic acid raw materials, comprising a mixing tank, a rotating shaft rotatably disposed inside the mixing tank, and an adjusting assembly disposed outside the rotating shaft, the adjusting assembly including a first motor fixedly disposed inside the rotating shaft.
[0006] The first motor has a lead screw fixedly installed at the end of its main shaft, and the other end of the lead screw is rotatably connected to the rotating shaft. A threaded sleeve is threadedly connected to the outside of the lead screw, and a stirring shaft body is rotatably installed on the outside of the threaded sleeve.

[0024] 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.
[0025] like Figures 1 to 5 As shown, this utility model provides a mixing device for processing benzoic acid raw materials, including a mixing tank 1, a rotating shaft 2 rotatably disposed inside the mixing tank 1, and an adjusting assembly 3 disposed outside the rotating shaft 2. The adjusting assembly 3 includes a first motor 301 fixedly disposed inside the rotating shaft 2.
[0026] A lead screw 302 is fixedly installed at the end of the main shaft of the first motor 301, and the other end of the lead screw 302 is rotatably connected to the rotating shaft 2. A threaded sleeve 303 is threadedly connected to the outer side of the lead screw 302, and a stirring shaft body 304 is rotatably installed on the outer side of the threaded sleeve 303. A fixed shaft 305 is rotatably connected to the inside of the stirring shaft body 304 near the threaded sleeve 303, and the fixed shaft 305 is fixedly connected to the rotating shaft 2. The first motor 301 drives the lead screw 302 to rotate, and the lead screw 302 drives the stirring shaft body 304 through the engagement of the threaded sleeve 303. Because of the restriction of the fixed shaft 305, the stirring shaft body 304 can only rotate and not move. In this way, the function of changing the angle of the stirring shaft is realized, which solves the problem that the mixing device cannot adjust the stirring shaft. By adjusting the angle of the stirring shaft, it can adapt to the mixing work of different formulas and the use of raw materials in various states. At the same time, it also has the function of reducing energy consumption and protecting equipment safety.
[0027] Specifically, a sliding baffle 4 is sleeved on the outer side of the stirring shaft body 304, and the sliding baffle 4 is in close contact with the inside of the rotating shaft 2. The sliding baffle 4 can prevent the raw material from entering the interior of the rotating shaft 2 through the hole on the outside.
[0028] Furthermore, multiple reinforcing sleeves 5 are fixedly installed inside the mixing tank 1, and the reinforcing sleeves 5 are rotatably connected to the rotating shaft 2. The reinforcing sleeves 5 are used to support both ends of the rotating shaft 2 and maintain its stability.
[0029] Furthermore, multiple fixed seats 6 are fixedly installed on the outside of the mixing tank 1, and a support seat 7 is fixedly installed on the top surface of the right fixed seat 6, and the support seat 7 is rotatably connected to the rotating shaft 2.
[0030] It is worth noting that a second motor 10 is fixedly installed on the top surface of the left fixed base 6, and a main gear 11 is fixedly installed at the end of the main shaft of the second motor 10. A driven gear 12 meshes with the outer side of the main gear 11, and the driven gear 12 is fixedly connected to the rotating shaft 2.
[0031] It is worth noting that a feed inlet 8 is fixedly provided on the top surface of the mixing tank 1, and a cover 9 is threadedly connected to the top surface of the feed inlet 8.
[0032] It is worth mentioning that the bottom surface of the mixing tank 1 is fixedly provided with a discharge port 13, and the bottom of the discharge port 13 is threadedly connected with a plug 14. The plug 14 is provided with a short shaft inside, which is flush with the inner wall of the mixing tank 1, so as to prevent raw materials from falling into the inside of the plug 14.
[0033] It is worth emphasizing that an active window 15 is fixedly installed on the outside of the mixing tank 1, and the active window 15 is located in the middle of the mixing tank 1. During mixing, the staff can open the active window 15 to observe the mixing of the raw materials inside.
[0034] The motor is existing technology and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The "front, back, left, and right" views of this device are... Figure 1 The direction shown in the diagram is the reference.
[0035] Working principle:
[0036] When using the mixing device for benzoic acid raw material processing, firstly, open the cover 9 and pour the raw material into the mixing tank 1 through the feed inlet 8. Then, turn on the first motor 301 in the adjusting assembly 3. The first motor 301 drives the lead screw 302 to rotate. The lead screw 302, through the engagement of the threaded sleeve 303, drives the stirring shaft body 304. Because of the restriction of the fixed shaft 305, the stirring shaft body 304 can only rotate and not move. This achieves the function of changing the angle of the stirring shaft, making it suitable for mixing various raw materials. The sliding baffle 4 here can prevent the raw material from falling in. The rotating shaft 2 is driven by the second motor 10, which drives the main gear 11. The main gear 11 drives the driven gear 12, which in turn drives the rotating shaft 2 to start mixing benzoic acid with other raw materials inside the mixing tank 1. The two ends of the mixing tank 1 are fixed by the fixed seat 6, and the support seat 7 is used to support one end of the rotating shaft 2. The part of the rotating shaft 2 inside the mixing tank 1 is reinforced by the reinforcing sleeve 5. The mixed raw materials are poured out from the discharge port 13. The plug 14 is used to block the discharge port 13. During stirring, the operator can open the movable window 15 to observe the internal mixing.
