Description

Technical Field

[0001] This invention relates to the field of chemical production technology, and in particular to a closed washing vessel for benzoyl peroxide. Background Technology

[0002] Benzoyl peroxide, as an important organic peroxide, is widely used in chemical fields such as plastic polymerization initiation, rubber vulcanization promotion, coating curing and food additives. Its product purity and moisture content directly affect the stability of downstream processing technology and the quality of the final product. Therefore, the washing process, as a key purification link in the production of benzoyl peroxide, puts forward stringent requirements on the separation efficiency, sealing performance, operational safety and material adaptability of the equipment. In existing technologies, traditional washing tanks mostly employ open or simple sealed structures, resulting in limited fit between the tank lid and body. Benzoyl peroxide is irritating and oxidizing, and during the washing process, it requires stirring and centrifugation, which can easily lead to material splashing or washing liquid leakage. This not only wastes raw materials but may also cause safety issues such as skin irritation and respiratory discomfort for operators. Existing equipment often uses a single filter layer for solid-liquid separation, with a simple pore distribution and limited filtration contact area. Furthermore, benzoyl peroxide easily adsorbs onto the filter pore surface during washing, causing blockage and reducing the washing water permeability rate. This results in excessively long separation time between raw materials and washing liquid. The scraping mechanism in existing equipment is mostly a fixed rigid scraper, which makes sharp contact with the inner wall of the filter cartridge. Long-term operation can easily cause wear on the inner wall of the filter cartridge, leading to filter pore deformation and reduced filtration accuracy.

[0003] Therefore, a closed washing vessel for benzoyl peroxide is proposed to solve the problem. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention provides a benzoyl peroxide sealed washing vessel to solve the problems described in the background section.

[0005] The purpose and effect of the benzoyl peroxide sealed washing tank of the present invention are achieved by the following specific technical means: it includes a tank body, the tank body is cylindrical in shape and hollow inside, a filter cylinder is installed inside the tank body, the filter cylinder is cylindrical and hollow inside, and has through-holes at both ends, and the filter cylinder is provided with neatly arranged filter holes, a base is provided at the bottom of the tank body, the base is disc-shaped, four support rods are provided below the base, the support rods raise the tank body so that it is off the ground, and a tank cover is provided on the top of the tank body.

[0006] Furthermore, a filter disc is provided below the filter cylinder. The filter cylinder and the filter disc have the same diameter and are fitted together. The filter disc also has neatly arranged filter holes.

[0007] Furthermore, a second contact block is provided on the inner wall of the filter cartridge, and a first baffle is provided on the filter disc.

[0008] Furthermore, a connecting block is fixedly connected to the bottom of the filter disc, and a stabilizing block is provided in conjunction with the connecting block. The stabilizing block has a concave shape inside that fits into the connecting block. The stabilizing block and the connecting block are connected by a sleeve. A second motor is provided at the bottom of the stabilizing block. The stabilizing block is driven by the second motor to move up and down. The stabilizing block restricts the connecting block from moving.

[0009] Furthermore, a turntable is provided above the filter disc. The turntable is circular and has a groove inside. A contact block is provided in the groove of the turntable.

[0010] Furthermore, a motor is installed above the can lid, and the motor is fixed inside the can lid. An extension rod is installed at the bottom of the motor, which passes through the can lid. A stop block is installed at the bottom of the extension rod, and the stop block and the contact block are matched. When the stop block rotates through the motor, the stop block rotates.

[0011] Furthermore, three connecting blocks are fixedly installed around the lower part of the extension rod. Two scrapers are connected to the outside of the connecting blocks, and the end of the outer scraper 25 that contacts the inner wall of the filter cylinder 15 is rounded.

[0012] Furthermore, two folding rods are provided above the second stop. The folding rods are divided into two sections with a rotatable collar in the middle, so that the folding rods 3 can be folded.

[0013] Furthermore, a connecting rod extends downward from the tail end of the folding rod, and an extension plate is provided at the bottom end of the connecting rod.

[0014] Furthermore, a telescopic spring is provided on the other side of the folding rod, and the other end of the telescopic spring is fixed to the extension rod.

[0015] Beneficial effects: 1. The extension plate is designed to be foldable. When it is necessary to stir the filter disc or scrape off the raw materials remaining on the filter disc, the extension rod applies force to the extension plate, making the extension plate parallel. When cleaning the inside of the device, the filter plate can also be scraped and cleaned, or the filter plate can be rotated and cleaned directly to prevent the extension plate from being severely worn due to prolonged contact.

[0016] 2. It adopts a dual filtration structure of filter cartridge and filter disc, both with uniformly distributed precision filter holes of 0.1-0.3mm in diameter, and the filter holes are staggered. Compared with the traditional single filtration structure, the filtration contact area is increased by more than 2 times. The dual motors work together to achieve multi-dimensional movement of the filter cartridge and filter disc. One motor drives both to rotate synchronously. The centrifugal force generated by the rotation accelerates the permeation and filtration of washing water. With the help of the scraper to remove the attached material in the filter holes in real time, it can effectively prevent the filter holes from clogging and ensure a stable filtration rate. Compared with the traditional washing tank, the separation time of raw materials and washing water is shortened by 40%-60%, and the moisture content of the separated material is lower, which significantly improves production efficiency and product quality.

[0017] 3. The end of the scraper that contacts the inner wall of the filter cartridge is rounded to avoid wear caused by rigid contact. At the same time, the scraper can remove the deposits on the inner wall of the filter cartridge, ensuring smooth filtration and extending the service life of the equipment.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] In this embodiment, refer to Figures 1-10 A benzoyl peroxide sealed washing tank includes a tank body 1, which is cylindrical in shape and hollow inside. A filter cartridge 15 is installed inside the tank body 1. The filter cartridge 15 is cylindrical, hollow inside, and has through-holes at both ends. The filter cartridge 15 has neatly arranged filter holes. When water and raw materials are washed, water can be discharged through the filter cartridge 15, thereby achieving rapid separation of raw materials and water and greatly improving the filtration efficiency for a single material. Furthermore, a base 11 is provided at the bottom of the tank body 1. The base 11 is in the shape of a disc. Four support rods 12 are provided below the base 11. The support rods 12 raise the tank body 1 so that it is off the ground. A tank cover 23 is provided on the top of the tank body 1 to prevent the raw materials inside the tank body 1 from not being sealed during the washing process. The filter cylinder 15 is provided with a filter plate 16 below it. The filter cylinder 15 and the filter plate 16 have the same diameter and are fitted together. The filter plate 16 is also provided with neatly arranged filter holes. A second contact block 22 is provided on the inner wall of the filter cartridge 15, and a first baffle 17 is provided on the filter disc 16. Furthermore, a receiving block 21 is fixedly connected to the bottom of the filter disc 16, and a stabilizing block 2 is provided in conjunction with the receiving block 21. The stabilizing block 2 has a concave shape inside that fits into the receiving block 21. The stabilizing block 2 and the receiving block 21 are connected by a sleeve. A motor 2 14 is provided at the bottom of the stabilizing block 2. The stabilizing block 2 is driven by the motor 2 14 to move up and down. The stabilizing block 2 restricts the receiving block 21 from moving, but it can rotate, thereby driving the filter disc 16 to rotate. Furthermore, when the filter disc 16 rotates, the first stop block 17 will also rotate. When the first stop block 17 rotates to the second contact block 22, the filter barrel 15 will be rotated through the second contact block 22. A turntable 18 is provided above the filter disc 16. The turntable 18 is circular and has a groove inside. A contact block 19 is provided in the groove of the turntable 18. Furthermore, a motor 13 is installed above the can lid 23 and is fixed inside the can lid 23. An extension rod 24 is installed at the bottom of the motor 13 and passes through the can lid 23. A stop block 28 is installed at the bottom of the extension rod 24 and is matched with a contact block 19. When the stop block 28 is rotated by the motor 13, the stop block 28 touches the contact block 19 and drives the filter disc 16 to rotate, which in turn causes the filter cartridge 15 to rotate. Among them, three connecting blocks 26 are fixedly installed around the bottom of the extension rod 24. Two scrapers 25 are connected to the outside of the connecting blocks 26. The end of the outer scraper 25 that contacts the inner wall of the filter cylinder 15 is rounded to prevent the scraper 25 from scraping the surface unevenly, thereby increasing wear. Furthermore, two folding rods 3 are provided above the second block 28. The folding rods 3 are divided into two sections, with a rotatable collar in the middle, so that the folding rods 3 can be folded. A connecting rod 29 is provided at the tail end of the folding rods 3, and an extension plate 27 is provided at the bottom end of the connecting rod 29. A telescopic spring 31 is provided on the other side of the folding rods 3, and the other end of the telescopic spring 31 is fixed to the extension rod 24. pass Figure 10 As shown, when the extension plate 27 retracts, the bottom of the extension plate 27 will be longer than the extension rod 24. When the extension rod 24 extends downward, the extension plate 27 will first contact the filter plate 16. Under the force of the extension rod 24, the extension plate 27 will be squeezed, so that the extension plate 27 becomes parallel through the force. When it is necessary to retract the extension plate 27, it is only necessary to retract the extension rod 24. Under the action of the telescopic spring 31, the extension plate 27 will be retracted.

[0031] The extension plate 27 is foldable. When it is necessary to stir the filter plate 16 or scrape off the raw materials remaining on the filter plate 16, the extension rod 24 applies force to the extension plate 27, so that the extension plate 27 becomes parallel. When cleaning the inside of the device, the filter plate 16 can also be scraped and cleaned, or the filter plate 16 can be rotated and cleaned directly to prevent the extension plate 27 from being severely worn due to long-term contact. The system employs a dual filtration structure consisting of a filter cartridge 15 and a filter disc 16. Both cartridges are equipped with precision filter pores with a diameter of 0.1-0.3mm, and the pores are arranged in a staggered manner. Compared with the traditional single filtration structure, the filtration contact area is increased by more than 2 times. The dual motors work together to achieve multi-dimensional movement of the filter cartridge 15 and the filter disc 16. Motor 13 drives the two to rotate synchronously. The centrifugal force generated by the rotation accelerates the permeation and filtration of washing water. In conjunction with the scraper 25, the filter pores are scraped off in real time, which can effectively prevent the filter pores from clogging and ensure a stable filtration rate. Compared with the traditional washing tank, the separation time between raw materials and washing water is shortened by 40%-60%, and the separated material has a lower moisture content, which significantly improves production efficiency and product quality. The end of the scraper 25 that contacts the inner wall of the filter cartridge 15 is rounded to avoid wear caused by rigid contact. At the same time, the scraper 25 can scrape off the deposits on the inner wall of the filter cartridge 15, ensuring smooth filtration and extending the service life of the equipment.
