Description

Technical Field

[0001] This invention belongs to the field of benzoyl peroxide preparation, specifically a device for preparing benzoyl peroxide to reduce acidity. Background Technology

[0002] Benzoyl peroxide, also known as benzoyl peroxide or initiator BPO, is an organic compound that appears as a white crystalline powder at room temperature with a faint bitter almond odor. This compound is soluble in organic solvents such as benzene, chloroform, and ether, and slightly soluble in ethanol and water. Benzoyl peroxide is generally prepared in a reaction vessel, and its pH needs to be controlled during the preparation process.

[0003] Chinese utility model patent CN212999974U discloses a fully stirred reaction vessel for the production of benzoyl peroxide, comprising a vessel body, a heating shell at the bottom of the vessel body with an internal gas channel, a heat-conducting plate fixedly installed on the top of the heating shell, a discharge pipe fixedly installed on one side of the heating shell, a control box fixedly installed on the front of the heating shell, a frequency converter fixedly installed inside the control box, and a PLC controller fixedly installed on one side of the frequency converter. This utility model incorporates a pressure differential and a pressure relief valve to detect the internal pressure of the reaction vessel. The pressure relief valve allows for pressure relief, increasing safety during use and reducing limitations. The combination of the frequency converter and PLC controller allows for adjustment and control of the reaction vessel's practicality, facilitating operation based on actual usage and improving its usability, thus expanding its applicability.

[0004] Regarding the aforementioned related technologies, the inventors believe that the following defects exist: the reaction vessel for producing benzoyl peroxide is inconvenient to sample and test its internal materials during the preparation of benzoyl peroxide, thus making it inconvenient to control the pH of benzoyl peroxide.

[0005] To address the problems raised in the background art, those skilled in the art have proposed an apparatus for preparing benzoyl peroxide to reduce acidity. Utility Model Content

[0006] To address the aforementioned technical problems, this invention provides a preparation apparatus for reducing the acidity of benzoyl peroxide, thereby solving the problem that in the prior art, the reaction vessel used for benzoyl peroxide production is inconvenient to sample and test its internal materials during the preparation of benzoyl peroxide, thus making it inconvenient to control the acidity and alkalinity of benzoyl peroxide.

[0007] A device for preparing benzoyl peroxide to reduce acidity includes a reaction vessel body, a feed pipe fixedly connected to the upper end of the reaction vessel body, and a discharge pipe fixedly connected to the lower end of the reaction vessel body. Valves are installed on both the feed pipe and the discharge pipe. A sampling component for sampling liquid is provided inside the reaction vessel body.

[0008] The sampling assembly includes a sampling tube slidably connected to the upper end of the reactor body, two symmetrically arranged through slots opened in the side wall of the sampling tube, and a sliding rod slidably connected to the two through slots. A connecting block is fixedly connected to the lower end of the sliding rod, and a sealing plug is fixedly connected to the upper surface of the connecting block.

[0009] Preferably, the sealing plug matches the inner diameter of the sampling tube, a pressing block is fixedly connected to the upper end of the slide rod, and springs are sleeved on the surfaces of both slide rods. The upper end of the spring is fixedly connected to the lower surface of the pressing block, and the lower end of the spring is fixedly connected to the upper end of the sampling tube.

[0010] Preferably, the reactor body includes a drive motor mounted on its upper end, and a rotating shaft is mounted on the output end of the drive motor. Several uniformly distributed stirring blades are welded to the surface of the rotating shaft.

[0011] Using the above technical solution, the application scenario of this device is to facilitate the control of the pH of benzoyl peroxide. Specifically, the material to be processed is poured into the reactor body through the feed pipe. The valve on the feed pipe is closed. The alkaline material to be neutralized is weighed and poured into the feed pipe. The valve is then opened to pour the material into the reactor body, allowing the alkaline material to react with the benzoyl peroxide for neutralization, thereby reducing the acidity of the benzoyl peroxide. Starting the drive motor drives the rotating shaft and its stirring blades to agitate the material, ensuring a more uniform mixture of the alkaline material and benzoyl peroxide. When it is necessary to test the pH value of benzoyl peroxide... Pressing down on the pressing block above the sampling tube compresses the spring, causing the sliding rod to push the connecting block downwards. This disengages the sealing plug from the sampling tube, allowing the benzoyl peroxide solution to enter. Releasing the pressing block returns the spring to its initial state, blocking the sampling tube. Moving the sampling tube upwards removes it from the reactor body, facilitating pH testing of the sampled benzoyl peroxide solution. This allows for further acid reduction of the solution compared to existing benzoyl peroxide production reactors. This device allows for convenient pH testing of the prepared benzoyl peroxide solution, enabling the subsequent addition of alkaline materials to lower its acidity.

[0012] Preferably, a rectangular plate is fixedly connected to the upper end of the reactor body, a rectangular groove is provided on one side of the rectangular plate, a rectangular block is slidably connected in the rectangular groove, and the sampling tube is installed in the rectangular block by bolts.

[0013] Preferably, a servo motor is installed at the upper end of the rectangular plate, and a threaded rod is installed at the output end of the servo motor. The threaded rod is threadedly connected to the rectangular block, and the lower end of the threaded rod is rotatably connected to the lower end of the rectangular groove.

[0014] Preferably, an outer tank is fixedly fitted onto the surface of the reactor body, an oil inlet pipe and an oil outlet pipe are fixedly connected to the side of the outer tank, a cylinder is fixedly connected to the upper end of the outer tank, and a support plate is rotatably connected to the upper end of the cylinder.

[0015] With the above technical solution, when in use, starting the servo motor can drive the threaded rod to rotate. When the threaded rod rotates, it can drive the rectangular block to move within the rectangular groove, thereby achieving the effect of adjusting the height of the sampling tube. This allows the lower end of the sampling tube to be adjusted to different positions within the reactor body, facilitating the sampling and testing of the solution at different heights within the reactor body. The tray is snapped onto the cylinder and is for single use. By rotating the tray, the lower end of the sampling tube can be held in place, thus facilitating the detection of the acidity and alkalinity of the solution.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model allows for the detection of the pH value of benzoyl peroxide. When pressing down on the sampling tube above the sampling tube, the spring is compressed. The sliding rod pushes the connecting block downwards, disengaging the sealing plug from the sampling tube. The benzoyl peroxide solution then enters the sampling tube. Releasing the pressing block returns the spring to its initial state, and the sealing plug blocks the sampling tube. Moving the sampling tube upwards removes it from the reactor body. This facilitates pH value detection of the sampled benzoyl peroxide, enabling further acid reduction of the solution. Compared to existing benzoyl peroxide production reactors, this device allows for convenient pH detection of the prepared benzoyl peroxide, facilitating the subsequent addition of alkaline materials to lower its acidity.

[0018] 2. This utility model uses a servo motor to drive a threaded rod to rotate. When the threaded rod rotates, it moves a rectangular block within a rectangular groove, thereby adjusting the height of the sampling tube. This allows the lower end of the sampling tube to be adjusted to different positions within the reactor body, facilitating sampling and testing of the solution at different heights within the reactor body. The tray is attached to the cylinder and is for single use. By rotating the tray, the lower end of the sampling tube can be held in place, facilitating the detection of the acidity and alkalinity of the solution. Attached Figure Description

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] Example 1: As shown in the attached document Figure 1 To be continued Figure 4 As shown: This utility model provides a preparation device for reducing the acidity of benzoyl peroxide, including a reaction vessel body 1, a feed pipe 101 fixedly connected to the upper end of the reaction vessel body 1, and a discharge pipe 102 fixedly connected to the lower end of the reaction vessel body 1. Valves are installed on both the feed pipe 101 and the discharge pipe 102. A sampling component for sampling liquid is provided inside the reaction vessel body 1.

[0027] The sampling assembly includes a sampling tube 3 slidably connected to the upper end of the reactor body 1, two symmetrically arranged through slots 301 opened in the side wall of the sampling tube 3, and a slide rod 302 slidably connected in the two through slots 301. A connecting block 303 is fixedly connected to the lower end of the slide rod 302, and a sealing plug 304 is fixedly connected to the upper surface of the connecting block 303.

[0028] The sealing plug 304 matches the inner diameter of the sampling tube 3. The upper end of the slide rod 302 is fixedly connected to the pressing block 305. The surfaces of the two slide rods 302 are covered with springs 306. The upper end of the springs 306 is fixedly connected to the lower surface of the pressing block 305, and the lower end of the springs 306 is fixedly connected to the upper end of the sampling tube 3.

[0029] The reactor body 1 includes a drive motor 103 mounted on its upper end. A rotating shaft 104 is mounted on the output end of the drive motor 103. Several uniformly distributed stirring blades 105 are welded to the surface of the rotating shaft 104.

[0030] As can be seen from the above, the application scenario of this device is to facilitate the control of the pH of benzoyl peroxide. Specifically, the material to be processed is poured into the reactor body 1 through the feed pipe 101. The valve on the feed pipe 101 is closed. The alkaline material to be neutralized is weighed and poured into the feed pipe 101. The valve is then opened to pour the material into the reactor body 1, allowing the alkaline material to react with the benzoyl peroxide for neutralization, thereby reducing the acidity of the benzoyl peroxide. Starting the drive motor 103 drives the rotating shaft 104 and its stirring blades 105 to stir the material, making the alkaline material and benzoyl peroxide mix more evenly. When it is necessary to detect the pH value of benzoyl peroxide, the sample is taken from above the sampling tube 3. Pressing down on the pressing block 305 compresses the spring 306. At this time, the sliding rod 302 pushes the connecting block 303 downward, and the sealing plug 304 disengages from the sampling tube 3. Subsequently, the benzoyl peroxide solution enters the sampling tube 3. After releasing the pressing block 305, the spring 306 returns to its initial state. At this time, the sealing plug 304 blocks the sampling tube 3. Moving the sampling tube 3 upward allows it to be removed from the reactor body 1. This facilitates pH testing of the sampled benzoyl peroxide, enabling further acid reduction of the benzoyl peroxide solution. Compared to existing benzoyl peroxide production reactors, this device allows for convenient acid-base testing of the benzoyl peroxide during preparation, facilitating the subsequent addition of alkaline materials to reduce its acidity.

[0031] Example 2: Based on Example 1, a rectangular plate 4 is fixedly connected to the upper end of the reactor body 1. A rectangular groove 401 is opened on one side of the rectangular plate 4. A rectangular block 402 is slidably connected in the rectangular groove 401. The sampling tube 3 is installed in the rectangular block 402 by bolts.

[0032] A servo motor 403 is mounted on the upper end of the rectangular plate 4. A threaded rod 404 is mounted on the output end of the servo motor 403. The threaded rod 404 is threadedly connected to the rectangular block 402. The lower end of the threaded rod 404 is rotatably connected to the lower end of the rectangular groove 401.

[0033] An outer tank 2 is fixedly mounted on the surface of the reactor body 1. An oil inlet pipe 201 and an oil outlet pipe 202 are fixedly connected to the side of the outer tank 2. A cylinder 5 is fixedly connected to the upper end of the outer tank 2. A support plate 501 is rotatably connected to the upper end of the cylinder 5.

[0034] As can be seen from the above, during use, the servo motor 403 can be started to drive the threaded rod 404 to rotate. When the threaded rod 404 rotates, it can drive the rectangular block 402 to move within the rectangular groove 401, thereby achieving the effect of adjusting the height of the sampling tube 3. This makes it convenient to adjust the lower end of the sampling tube 3 to different positions within the reactor body 1, thus facilitating the sampling and testing of the solution at different heights within the reactor body 1. The tray 501 is snapped onto the cylinder 5 and is for single use. By rotating the tray 501, the lower end of the sampling tube 3 can be caught, thus facilitating the detection of the acidity and alkalinity of the solution.
