Description

Technical Field

[0001] The utility model relates to the technical field of chemical synthesis, in particular to a purification and synthesis device for 1,2-benzisothiazol-3-one. Background Art

[0002] 1,2-Benzisothiazol-3-one is a main industrial bactericide, antiseptic and anti-enzyme agent. It has outstanding inhibitory effects on the growth of microorganisms such as molds (fungi, bacteria), algae, etc. in organic media.

[0003] When purifying 1,2-benzisothiazol-3-one, acid-base reagents are put into 1,2-benzisothiazol-3-one to cause a chemical reaction between 1,2-benzisothiazol-3-one and the acid-base reagents for purification. Currently, when 1,2-benzisothiazol-3-one is put into the mixing box, the agglomerated 1,2-benzisothiazol-3-one is not filtered, which makes it difficult for the agglomerated 1,2-benzisothiazol-3-one to quickly contact the acid-base reagents, thereby prolonging the purification time of 1,2-benzisothiazol-3-one; when 1,2-benzisothiazol-3-one is mixed in the mixing box, a stirring rod is arranged on the mixing box to stir 1,2-benzisothiazol-3-one and the acid-base reagents. However, the stirring force of the horizontal structure in the stirring rod has limitations, making it difficult for a large amount of 1,2-benzisothiazol-3-one to fully blend with the acid-base reagents, thereby affecting the purification efficiency of 1,2-benzisothiazol-3-one. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem of poor mixing efficiency between 1,2-benzisothiazol-3-one and acid-base reagents in the prior art, and to propose a purification and synthesis device for 1,2-benzisothiazol-3-one.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A purification and synthesis device for 1,2-benzisothiazol-3-one, including a box body and a mixing box. A partition board with a blanking port is integrally connected inside the box body. The box body is divided into an upper cavity and a lower cavity by the partition board. The mixing box is placed in the lower cavity. A limiting rod is fixedly installed in the upper cavity. A sliding block is slidably sleeved on the limiting rod. A fine filter frame for intercepting agglomerated benzisothiazol-3-one is integrally connected between the two sliding blocks.

An upper rod and a lower rod connected to the second spring are slidably sleeved inside the deflection rod. A scraper for cleaning the inner wall of the mixing tank is provided on the upper rod. A sleeve is fixedly installed on the upper rod. A support rod extending into the sleeve and used for stirring benzisothiazolin-3-one and acid-base reagents is fixedly installed on the lower rod.

[0008] Preferably, the partition board is horizontally arranged, and the limiting rods are vertically arranged on both sides of the fine filter frame. A coarse filter frame for filtering agglomerated benzisothiazolin-3-one is placed on the box body.

[0009] Preferably, a guide rod is fixedly installed inside the box body, and a guide block is slidably sleeved on the guide rod. A first spring is welded between the guide block and the box body. A connecting rod is connected between the guide block and the fine filter frame.

[0012] Preferably, the second spring is horizontally welded. The scraper is located on the side of the upper rod extending outside the deflection rod, and the scraper is an arc-shaped structure adapted to the mixing tank.

[0013] Compared with the prior art, the present utility model has the following advantages:

[0015] 2. By driving the motor, the two deflection rods can stir benzisothiazolin-3-one and acid-base reagents during rotation, and the support rod and the sleeve can stir benzisothiazolin-3-one and acid-base reagents during rotation.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Referring to Figures 1-3 , a purification and synthesis device for 1,2 - benzisothiazol - 3 - one, comprising a box body 1 and a mixing box 2;

[0022] Inside the box body 1, there is an integrally connected partition board 3 with a material - discharging port. The box body 1 is divided into an upper cavity and a lower cavity by the partition board 3. The mixing box 2 is placed in the lower cavity. Inside the upper cavity, a limiting rod 4 is fixedly installed. A slider 6 is slidably sleeved on the limiting rod 4. Between the two sliders 6, there is an integrally connected fine filter frame 7 for intercepting agglomerated benzisothiazol - 3 - one. The limiting rod 4 guides the slider 6, enabling the slider 6 to stably pull the fine filter frame 7 during movement;

[0023] The partition board 3 is horizontally arranged, and the limiting rod 4 is vertically arranged on both sides of the fine filter frame 7. A coarse filter frame 11 for filtering agglomerated benzisothiazol - 3 - one is placed on the box body 1. By setting the coarse filter frame 11 on the box body 1 and the fine filter frame 7 in the upper cavity, the coarse filter frame 11 and the fine filter frame 7 can intercept agglomerated benzisothiazol - 3 - one;

[0024] Inside the box body 1, a guide rod 5 is fixedly installed, and a guide block 8 is slidably sleeved on the guide rod 5. A first spring 9 is welded between the guide block 8 and the box body 1. A connecting rod 10 is connected between the guide block 8 and the fine filter frame 7. The guide rod 5 is horizontally arranged below the fine filter frame 7. The two ends of the connecting rod 10 are respectively pin-connected to the guide block 8 and the fine filter frame 7. By arranging the guide rod 5 inside the box body 1 and arranging the connecting rod 10 between the guide block 8 and the fine filter frame 7, when benzisothiazolin-3-one enters the fine filter frame 7, the fine filter frame 7 will exert pressure on the connecting rod 10, thereby causing the fine filter frame 7 to slowly move downward and filter the benzisothiazolin-3-one, thereby reducing the purification time of benzisothiazolin-3-one;

[0025] On the partition plate 3, a motor 12 is fixedly installed, and a fixed rod 13 is fixedly connected to the output end of the motor 12. After the motor 12 is powered on, it drives the fixed rod 13 to rotate. This technical solution is an existing technology and will not be elaborated here. A moving rod 14 is slidably sleeved inside the fixed rod 13. The fixed rod 13 and the moving rod 14 are vertically arranged from top to bottom. A fixing bolt corresponding to the moving rod 14 is threadedly connected to the fixed rod 13, and two deflecting rods 15 are horizontally arranged correspondingly. The fixed rod 13 and the moving rod 14 are connected by the fixing bolt. When the deflecting rod 15 is not in use, the moving rod 14 is pushed into the fixed rod 13, enabling the operator to take out the rotating stirring structure and clean it;

[0026] Deflecting rods 15 for stirring benzisothiazolin-3-one and acid-base reagents are fixedly installed on both the fixed rod 13 and the moving rod 14. A second spring 16 is welded inside the deflecting rod 15. An upper rod 17 and a lower rod 18 connected to the second spring 16 are slidably sleeved inside the deflecting rod 15. A scraping plate 19 for cleaning the inner wall of the mixing box 2 is arranged on the upper rod 17;

[0027] The second spring 16 is horizontally welded. The scraping plate 19 and the upper rod 17 extend to one side outside the deflecting rod 15, and the scraping plate 19 is an arc-shaped structure adapted to the mixing box 2. A sleeve 20 is fixedly installed on the upper rod 17. A support rod 21 for stirring benzisothiazolin-3-one and acid-base reagents is fixedly installed on the lower rod 18 and extends into the sleeve 20;

[0028] After the motor 12 is powered on, it drives the fixed rod 13 and the moving rod 14 to rotate. The deflecting rod 15 drives the upper rod 17 and the lower rod 18 that generate centrifugal force to rotate. The upper rod 17 drives the scraping plate 19 to extend outward and contact the inner wall of the mixing box 2, thereby scraping off the benzisothiazolin-3-one adhering to the inner wall of the mixing box 2;

[0029] When the two deflection rods 15 rotate, they can stir the benzisothiazolin-3-one and the acid-base reagent in the upper and lower layers. The sleeve 20 and the support rod 21 can stir the benzisothiazolin-3-one and the acid-base reagent in the mixing box 2, so that the benzisothiazolin-3-one and the acid-base reagent can be quickly mixed, thereby improving the purification efficiency of benzisothiazolin-3-one.

[0030] The functional principle of the present utility model can be elaborated through the following operation methods:

[0031] Apply pressure to the moving rod 14 to make the moving rod 14 slide within the fixed rod 13. The moving rod 14 drives the deflection rod 15 to move downward into the mixing box 2. At the same time, the moving rod 14 drives the support rod 21 to slide within the sleeve 20, and use a fixing bolt to connect the fixed rod 13 and the moving rod 14;

[0032] Put the crystallized benzisothiazolin-3-one into the coarse filter frame 11. The coarse filter frame 11 and the fine filter frame 7 can filter the agglomerated benzisothiazolin-3-one;

[0033] After the benzisothiazolin-3-one enters the fine filter frame 7, the weight of the benzisothiazolin-3-one will apply pressure to the fine filter frame 7, causing the fine filter frame 7 to move downward and apply pressure to the connecting rod 10. The connecting rod 10 deflects under force and applies pressure to the guide block 8, and the first spring 9 is stressed. When the weight of the benzisothiazolin-3-one decreases, the fine filter frame 7 can automatically move upward slowly;

[0034] After the benzisothiazolin-3-one is filtered, it enters the mixing box 2 through the material outlet on the partition plate 3;

[0035] The output end of the motor 12 drives the fixed rod 13 to rotate. The fixed rod 13 drives the moving rod 14 to rotate. The fixed rod 13 and the moving rod 14 drive the two deflection rods 15 to rotate, so that the deflection rods 15 stir the benzisothiazolin-3-one and the acid-base reagent;

[0036] When the deflection rod 15 rotates, it generates centrifugal force on the upper rod 17 and the lower rod 18, and the second spring 16 is stressed, causing the upper rod 17 to drive the scraper 19 to move outward and rotate. The scraper 19 can clean the inner wall of the mixing box 2 when rotating. The upper rod 17 drives the sleeve 20, the support rod 21, and the lower rod 18 to rotate and stir the benzisothiazolin-3-one and the acid-base reagent;

[0037] The benzisothiazolin-3-one and the acid-base reagent can be purified after a chemical reaction.

[0038] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
