Description

Technical Field

[0001] The invention belongs to the technical field of benzoyl oxide production, in particular to an impurity removal device for benzoyl oxide production. Background Art

[0002] Benzoyl oxide is an important organic compound that is widely used in chemical industry, medicine, plastics and other fields. In its production process, purity is a key indicator, and impurity removal is an important step to improve purity. In the synthesis process of benzoyl oxide, due to various factors such as incomplete reaction of raw materials, side reactions during the reaction process or impurities introduced by the production environment, the final product is often mixed with various impurities. These impurities may include unreacted raw materials, by-products generated during the reaction process, and some inorganic impurities such as dust, metal ions, etc. For example, if the raw material benzoyl chloride is not completely reacted, it will remain in the product; and during the reaction, Due to fluctuations in oxidation reaction conditions, some by-products with similar structures but different properties may be produced. Among them, inorganic impurities may come from wear and tear of production equipment, contamination of storage containers, or trace impurities carried by the raw materials themselves. The presence of these impurities will have a multi-faceted impact on the quality of benzoyl oxide. First of all, in terms of chemical properties, impurities may change the reactivity and stability of the product. In terms of physical properties, impurities will affect the product's appearance, melting point, boiling point and other physical parameters. Impure benzoyl oxide may show color changes and a wider melting point range, which is unacceptable for application scenarios that require high-precision physical parameters.

[0003] The existing impurity removal device for benzoyl oxide production does not have a cleaning structure. During use, due to the presence of sticky impurities in the product, the impurities are easily attached to the inner wall of the impurity removal device. Over time, these attached impurities may accumulate more and more. Long-term accumulation is likely to affect the normal operation and impurity removal effect of the impurity removal device, and is also likely to cause clogging of the filter pores. When the filter pores are clogged, the filtration efficiency will be greatly reduced, and the entire impurity removal process may be obstructed. Therefore, a impurity removal device for benzoyl oxide production is proposed. Summary of the Invention

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figures 1 to 8 As shown, the present invention provides an impurity removal device for producing benzoyl oxide, including a main body mechanism 4, and further comprising:

[0032] The cleaning mechanism 1 is arranged inside the main body mechanism 4;

[0033] Among them, the cleaning mechanism 1 includes a motor 101, a gear ring 103, a spiral cone 104, a cleaning scraper 106, a scraping plate 105, a rotating drum 107, and a groove 109. The motor 101 is rotatably connected to the gear 102. The bottom of the gear ring 103 is fixedly connected to a spiral cone 104 for pressurizing the liquid. The bottom of the gear ring 103 is fixedly connected to two cleaning scrapers 106 for cleaning the inner wall of the device. The bottom of the spiral cone 104 is fixedly connected to a scraping plate 105 for preventing the filter from being blocked. The side of the scraping plate 105 is fixedly connected to the rotating drum 107, and two grooves 109 are provided at the bottom of the rotating drum 107.

[0034] The side of the gear 102 is meshed with the gear ring 103, and a bevel groove 108 is provided on the side of the rotating drum 107 close to the scraper plate 105. The size of the gear ring 103 is larger than the size of the gear 102, and the size of the bottom of the spiral cone 104 is smaller than the size of the top of the spiral cone 104. The shape of the cleaning scraper 106 is arc-shaped, and the shape of the scraper plate 105 is cross-shaped. The bottom of the cleaning scraper 106 is fixedly connected to the top of the rotating drum 107, and the shape of the groove 109 is an isosceles trapezoid. The spiral cone 104 is located between the two cleaning scrapers 106.

[0035] A filtering mechanism 2 is provided inside the cleaning mechanism 1, and the filtering mechanism 2 includes a filter plate 201, on which a plurality of first filter holes 202 are evenly opened, a sliding plate 203 is provided at the bottom of the filter plate 201, on which a plurality of second filter holes 205 are evenly opened, a plurality of recoil rods 204 are fixedly connected to the top of the sliding plate 203, and sliders 206 are fixedly connected on both sides of the sliding plate 203, and baffles 207 are fixedly connected to the top and bottom of the slider 206, and a spring 208 is fixedly connected to the bottom of the slider 206.

[0036] The above solution is adopted: by setting up the coordination of structures such as the spiral cone 104 and the cleaning scraper 106, the problem of impurities adhering to the inner wall of the device and clogging the first filter hole 202 on the impurity removal effect is solved. The motor 101 is started to rotate the gear 102. The rotation of the gear 102 will drive the gear ring 103 engaged with it to rotate. The rotation of the gear ring 103 will drive the spiral cone 104 fixedly connected to its bottom to rotate. The spiral blades on its surface exert downward pressure on the product, which can prompt the product to flow downward faster in the device, which helps to improve the processing speed of the entire impurity removal process. The faster the product flows, the more impurity removal links it can pass through per unit time, thereby improving the overall working efficiency of the impurity removal device, reducing the residence time of the product in the device, and increasing the production throughput. The rotation of the spiral cone 104 will drive the scraper 105 fixedly connected to its bottom to rotate. The rotation of the gear ring 103 and the scraper 105 will cause the cleaning scraper 106 between the two to rotate along the inner wall of the main shell 401, which can directly scrape off these attached impurities. 201 , so that the impurities therein can be filtered out better. At the same time, the product can be promoted to flow continuously, and blockage or deposition of the product in certain parts of the device can be prevented. As the filtration proceeds, impurities will gradually settle and accumulate on the top of the filter plate 201. The scraper plate 105 is rotatably connected to the top of the filter plate 201, and the impurities settled on the top of the filter plate 201 can be scraped off by the inclined surface on the scraper plate 105. After the scraper plate 105 scrapes off the precipitated impurities, the first filter hole 202 of the filter plate 201 is kept unobstructed, so that the impurities in the benzoyl oxide can be filtered out continuously and effectively. In this way, it can be ensured that the filter plate 201 always maintains a high filtration efficiency during the long-term impurity removal process, and the filtration effect will not be reduced due to impurity blockage, thereby ensuring the stable operation of the impurity removal device.

[0037] By providing the cooperation of the structures such as the groove 109 and the slider 206, it is convenient to drive the recoil rod 204 to recoil the first filter hole 202. As the drum 107 rotates, the groove 109 squeezes the top of the slider 206 through the inclined surface, so that under the action of pressure, the sliding plate 203 is driven downward and squeezes the spring 208. When the groove 109 at the bottom of the drum 107 rotates to a position not aligned with the slider 206, the end of the slider 206 away from the sliding plate 203 is located below the drum 107. At this time, the recoil rod 204 is separated from the first filter hole 202. At this time, the liquid can pass through the first filter hole 202 and the second filter hole 205 normally to be filtered, and When the drum 107 rotates half a circle, the groove 109 at the bottom of the drum 107 is realigned with the slider 206. At this time, the slider 206 will move upward under the action of the elastic force of the spring 208, driving the recoil rod 204 on the sliding plate 203 to reset and recoil the first filter hole 202, preventing some impurities from entering the first filter hole 202 and clogging the first filter hole 202. Impurities that may clog the first filter hole 202 can be cleaned in time to ensure that the filtering functions of the first filter hole 202 and the second filter hole 205 remain stable throughout the entire impurity removal process, thereby maintaining a stable filtration efficiency, ensuring that the impurity removal work can be carried out continuously and efficiently, and indirectly improving the impurity removal effect.

[0038] like Figures 2 to 4 As shown, the size of the sliding plate 203 is the same as that of the filter plate 201, the size of the first filter hole 202 is larger than that of the second filter hole 205, the size of the recoil rod 204 is adapted to the size of the first filter hole 202, a plurality of recoil rods 204 correspond to a plurality of first filter holes 202 respectively, and a plurality of recoil rods 204 are staggered with a plurality of second filter holes 205. The shape of the slider 206 is "L"-shaped, and the spring 208 on the slider 206 is located on the side of the baffle 207 away from the sliding plate 203. The filter plate 201 and the sliding plate 203 are both located inside the drum 107, and the ends of the two sliders 206 away from the sliding plate 203 are both located inside the groove 109. The bottom of the scraper plate 105 fits in place with the top of the filter plate 201.

[0039] An adsorption mechanism 3 is provided below the filtering mechanism 2 and is located inside the main body mechanism 4. The adsorption mechanism 3 includes an activated carbon layer 301. Several ion exchange resins 302 are provided inside the activated carbon layer 301. A microporous filter 303 is provided at the bottom of the activated carbon layer 301. Several ion exchange resins 302 are evenly distributed inside the activated carbon layer 301. The activated carbon layer 301 is located below the sliding plate 203 and between the two sliders 206.

[0040] The main body mechanism 4 includes a main shell 401, a discharge port 402 is provided on the side of the main shell 401, a valve 403 is provided inside the discharge port 402, two slide grooves 404 are provided on the inner wall of the main shell 401, a feed port 405 is provided on the top of the main shell 401, and a discharge port 406 is provided at the bottom of the main shell 401.

[0041] The gear ring 103 is rotatably connected to the inner wall of the main shell 401, the motor 101 is fixedly connected to the side of the main shell 401, the valve 403 is located above the rotating drum 107, the microporous filter 303 and the gear ring 103 are both located between the feed port 405 and the discharge port 406, the slider 206 is slidably connected to the inner wall of the chute 404, the bottom of the slider 206 is elastically connected to the inner wall of the chute 404 through the spring 208, the cleaning scraper 106 is fitted to the inner wall of the main shell 401, the filter plate 201 is fixedly connected to the inner wall of the main shell 401, the rotating drum 107 is rotatably connected to the inner wall of the chute 404, the sliding plate 203 is slidably connected to the inner wall of the main shell 401, and the activated carbon layer 301 and the microporous filter 303 are both fixedly connected to the inner wall of the main shell 401.

[0042] The above scheme is adopted: by setting up the combination of the activated carbon layer 301 and the ion exchange resin 302, the impurity removal effect of the device is improved. After being filtered by the filter plate 201 and the sliding plate 203, the product will enter the activated carbon layer 301. The activated carbon has a huge specific surface area and rich microporous structure, and has a strong adsorption capacity for organic impurities and pigments in the benzoyl oxide with a certain viscosity, and can clean up this part of the impurities in the benzoyl oxide. The ion exchange resin 302 in the activated carbon layer 301 can react with the metal ions in the benzoyl oxide to remove these metal ion impurities. , which can significantly improve the purity of benzoyl oxide, meet more stringent industrial production or other application requirements, and ensure the stable performance of the product during storage and use. Finally, the tiny particles in the product are filtered out through the microporous filter 303 to complete the removal of solid impurities and metal ions in the product. Through multi-stage filtration of the filter plate 201, the sliding plate 203, the activated carbon layer 301, the ion exchange resin 302 and the microporous filter 303, impurities are removed from different aspects and at different scales, which greatly improves the purity of the benzoyl oxide product and the impurity removal effect of the device, thereby improving the stability of product quality.

[0043] The working principle and use process of the present invention are as follows: first, the product after the production of benzoyl oxide enters the interior of the main shell 401 through the feed port 405, and at the same time, the motor 101 is started to rotate the gear 102. The rotation of the gear 102 will drive the gear ring 103 engaged with it to rotate, and the rotation of the gear ring 103 will drive the spiral cone 104 fixedly connected to its bottom to rotate. The spiral blades on its surface exert downward pressure on the product, which can promote the product to flow downward faster in the device, which helps to improve the processing speed of the entire impurity removal process. The faster the product flows, the more impurity removal links it can pass through per unit time, and the rotation of the spiral cone 104 will drive the scraper plate 105 fixedly connected to its bottom to rotate, and the spiral cone 104 will rotate. The rotation of 103 and the scraper plate 105 will cause the cleaning scraper 106 between them to rotate along the inner wall of the main body shell 401, which can directly scrape off these attached impurities, and prevent these impurities from accumulating for a long time and affecting the normal operation and impurity removal effect of the impurity removal device. The rotation of the scraper plate 105 and the cleaning scraper 106 can have a stirring effect on the product, so that the benzoyl oxide product is fully in contact with the top of the filter plate 201, so that the impurities therein can be better filtered out. As the filtration proceeds, the impurities will gradually settle and accumulate on the top of the filter plate 201, and the scraper plate 105 is rotatably connected to the top of the filter plate 201, so that the impurities settled on the top of the filter plate 201 can be scraped off through the inclined surface on the scraper plate 105;

[0044] When the groove 109 at the bottom of the drum 107 rotates to a position not aligned with the slider 206, the end of the slider 206 away from the sliding plate 203 is located below the drum 107. At this time, the recoil rod 204 is separated from the first filter hole 202. At this time, the liquid can pass through the first filter hole 202 and the second filter hole 205 normally and be filtered. When the drum 107 rotates half a circle, the groove 109 at the bottom of the drum 107 is aligned with the slider 206 again. At this time, the slider 206 will move upward under the elastic force of the spring 208, driving the recoil rod 204 on the sliding plate 203 to reset and recoil the first filter hole 202, thereby preventing some impurities from entering the first filter hole 202 and clogging the first filter hole 202.

[0045] After being filtered by the filter plate 201 and the sliding plate 203, the product enters the activated carbon layer 301. The activated carbon has a large specific surface area and rich microporous structure, and has a strong adsorption capacity for organic impurities, pigments, etc. in the benzoyl oxide with a certain viscosity, so it can clean up these impurities in the benzoyl oxide. The ion exchange resin 302 in the activated carbon layer 301 can react with the metal ions in the benzoyl oxide to remove these metal ion impurities, thereby significantly improving the purity of the benzoyl oxide, meeting more stringent industrial production or other application requirements, and ensuring the stable performance of the product during storage and use. Finally, the microporous filter 303 is used to filter out the tiny particles in the product to complete the removal of solid impurities and metal ions in the product.

[0046] After the product is discharged through the discharge port 406, it will be transported to the inside of the distillation, extraction or crystallization device to remove liquid impurities in the product, and finally a relatively pure benzoyl oxide product will be obtained. After this batch of products is discharged from the discharge port 406, since the device is inclined toward the discharge port 402, the filtered large particles of impurities will accumulate at the valve 403. At this time, the valve 403 can be opened to discharge these impurities through the discharge port 402.
