Description

Technical Field

[0001] This utility model relates to the field of chemical filtration device technology, and in particular to a device for rapidly filtering 5-bromo-2-chlorobenzoic acid. Background Technology

[0002] 5-Bromo-2-chlorobenzoic acid, as an important pharmaceutical intermediate and fine chemical raw material, typically requires effective separation of the solid product from the mother liquor during its post-synthesis processing or purification. The efficiency and effectiveness of this solid-liquid separation process directly affect the product yield, purity, and the smooth progress of subsequent processes.

[0003] In existing technologies, the filtration of such materials mostly employs traditional gravity filtration or vacuum filtration. Gravity filtration relies on natural gravity to drive the liquid phase through the filter media, resulting in slow separation speeds and small throughput. Especially for 5-bromo-2-chlorobenzoic acid suspensions containing fine particles or prone to forming dense filter cakes, clogging of the filter media is highly likely, leading to a sharp decline in filtration efficiency and even making continuous operation impossible. While vacuum filtration can increase the filtration driving force to some extent through negative pressure, it still suffers from time-consuming issues when processing large-scale materials. Furthermore, after filtration using these traditional methods, solid residues easily remain on the filter media (such as filter cloth and filter paper), making the cleaning process cumbersome. This not only increases the labor intensity of workers but also poses a risk of cross-contamination between different batches of products due to incomplete cleaning, affecting product quality consistency.

[0004] Furthermore, although centrifuge technology has been applied in the field of chemical separation, conventional centrifuge equipment is complex in structure, expensive, and often not optimized for the specific process characteristics of chemicals such as 5-bromo-2-chlorobenzoic acid. After separation, the drum or filter basket of some equipment requires manual disassembly for cleaning, which is inconvenient, time-consuming, and fails to meet the urgent needs of modern chemical production for high efficiency, high automation, and good cleanliness (CIP). Especially for high-value products like 5-bromo-2-chlorobenzoic acid, rapid and thorough separation and convenient equipment maintenance are key to reducing production costs and improving economic efficiency. Therefore, a rapid filtration device for 5-bromo-2-chlorobenzoic acid is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0006] Therefore, one objective of this invention is to provide a device for rapidly filtering 5-bromo-2-chlorobenzoic acid, in order to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0007] To achieve the above objectives, one embodiment of the present invention provides a device for rapid filtration of 5-bromo-2-chlorobenzoic acid, comprising a support, a tank, connectors, a rotating rod, and a tank cover. The top of the support is fixedly connected to the tank, and several connectors are fixedly connected around the top opening of the tank. A rotating rod is movably connected to the inner side of each connector. The top of the tank is detachably connected to a can lid, and several bayonets are fixedly connected to the edge of the can lid. The rotating rod enters the bayonets, and a fastener is threaded to the top of the rotating rod and is tightened on the top surface of the bayonets. A motor is fixedly connected to the center of the top surface of the can lid. An inner frame is fixedly connected to the outer surface of the output end of the motor. A filter shell is fixedly connected to the end of the inner frame. The top of the filter shell is open. A shell bottom is detachably connected to the bottom of the filter shell. Several filter holes are opened on the filter shell and the shell bottom. A liquid outlet pipe is fixedly connected to the bottom of the tank body, and a liquid injection pipe is fixedly connected to the top of the tank cover. The output end of the liquid injection pipe faces the inside of the filter shell. A first nozzle and a second nozzle are fixedly connected to the top of the tank cover. The bottom of the first nozzle and the second nozzle face the inner wall and outer wall of the filter shell, respectively. An electric control valve is integrated on the liquid injection pipe, the first nozzle, and the second nozzle.

[0008] Preferably, in any of the above solutions, the bracket is welded to the tank body, and the tank body is made of stainless steel.

[0009] The above technical solution utilizes centrifugal force generated by high-speed rotation to achieve solid-liquid separation. During filtration, the 5-bromo-2-chlorobenzoic acid mixture to be filtered is injected into the filter shell through a liquid injection pipe. A motor drives the inner frame to rotate, causing the filter shell to rotate at high speed. Under centrifugal force, the liquid is thrown outwards through the filter shell and the filter holes on the bottom, while solid particles are retained inside the filter shell, thus completing solid-liquid separation.

[0010] This device features a self-cleaning structure that allows the filter housing to self-clean even when the tank is empty. The process is as follows: First, cleaning fluid is injected into the filter housing through the injection pipe. The motor then rotates the filter housing at high speed, causing the cleaning fluid to pass through the filter holes and exit, thus providing initial cleaning. Subsequently, the first and second nozzles activate. The first nozzle sprays directly onto the inner wall of the filter housing, while the second nozzle sprays directly onto the outer wall. The jets wash the surfaces, and simultaneously, the motor continues to rotate the filter housing, achieving effective self-cleaning of the filtration mechanism.

[0011] Preferably, the bayonet is arranged in a circumferential array about the axis of the can lid, and the fastener is specifically a ring nut.

[0012] The core design of the device is as follows: This device uses centrifugal force generated by high-speed rotation to achieve solid-liquid separation. Compared with traditional filtration methods, it can separate solid particles and liquid in a mixture of 5-bromo-2-chlorobenzoic acid more quickly, greatly improving filtration efficiency and saving filtration time. It is suitable for large-scale production scenarios with high requirements for filtration speed.

[0013] The device is equipped with a self-cleaning structure that allows for a thorough cleaning of the filtration mechanism after filtration. Cleaning solution is injected through the injection pipe, and the high-speed rotation of the filter housing forces the solution through the filter holes for initial cleaning. Then, high-pressure rinsing of the inner and outer walls of the filter housing is achieved through the first and second nozzles, simultaneously with the rotation of the filter housing, resulting in effective self-cleaning of the filtration mechanism. This function effectively prevents filter hole clogging and residual impurities on the filter housing surface, ensuring the effectiveness and quality of each filtration, reducing the workload and cost of manual cleaning, and extending the device's lifespan.

[0014] Preferably, of any of the above solutions, the motor is installed vertically and connected to the tank cover via a flange.

[0015] Preferably, in any of the above embodiments, the end of the inner frame is riveted to the outer surface of the motor output end, and the filter shell is threaded to the bottom of the shell.

[0016] Preferably, in any of the above embodiments, the outer ends of the injection pipe, the first nozzle, and the second nozzle are all connected to a liquid pump, and the first nozzle and the second nozzle are high-pressure types.

[0017] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: This rapid filtration device for 5-bromo-2-chlorobenzoic acid utilizes centrifugal force generated by high-speed rotation to achieve solid-liquid separation. Compared with traditional filtration methods, it can separate solid particles and liquid in a 5-bromo-2-chlorobenzoic acid mixture more quickly, greatly improving filtration efficiency and saving filtration time. It is suitable for large-scale production scenarios with high requirements for filtration speed.

[0018] The device is equipped with a self-cleaning structure that allows for a thorough cleaning of the filtration mechanism after filtration. Cleaning solution is injected through the injection pipe, and the high-speed rotation of the filter housing forces the solution through the filter holes for initial cleaning. Then, high-pressure rinsing of the inner and outer walls of the filter housing is achieved through the first and second nozzles, simultaneously with the rotation of the filter housing, resulting in effective self-cleaning of the filtration mechanism. This function effectively prevents filter hole clogging and residual impurities on the filter housing surface, ensuring the effectiveness and quality of each filtration, reducing the workload and cost of manual cleaning, and extending the device's lifespan.

[0024] like Figure 1-4 As shown, this rapid filtration device for 5-bromo-2-chlorobenzoic acid includes a support 1, a tank 2, a connector 3, a rotating rod 4, and a tank cover 5. The top of the support 1 is fixedly connected to the tank 2, and several connectors 3 are fixedly connected around the top opening of the tank 2. The rotating rod 4 is movably connected to the inside of the connector 3. The top of the tank body 2 is detachably connected to a tank cover 5. Several bayonets 6 are fixedly connected to the edge of the tank cover 5. The rotating rod 4 enters the bayonets 6. The top of the rotating rod 4 is threadedly connected to a fastener 7, which is fastened to the top surface of the bayonets 6. A motor 8 is fixedly connected to the center of the top surface of the can lid 5. An inner frame 9 is fixedly connected to the outer surface of the output end of the motor 8. A filter shell 10 is fixedly connected to the end of the inner frame 9. The top of the filter shell 10 is open. A shell bottom 11 is detachably connected to the bottom of the filter shell 10. Several filter holes are opened on the filter shell 10 and the shell bottom 11. A liquid outlet pipe 12 is fixedly connected to the bottom of the tank body 2, and a liquid injection pipe 13 is fixedly connected to the top of the tank cover 5. The output end of the liquid injection pipe 13 faces the inside of the filter shell 10. A first nozzle 14 and a second nozzle 15 are fixedly connected to the top of the tank cover 5. The bottom of the first nozzle 14 and the second nozzle 15 faces the inner wall and the outer wall of the filter shell 10, respectively. An electric control valve is integrated on the liquid injection pipe 13, the first nozzle 14, and the second nozzle 15.

[0025] Example 1: The bracket 1 is welded to the tank body 2, which is made of stainless steel. The bayonet 6 is arranged circumferentially around the axis of the tank cover 5, and the fastener 7 is specifically a ring nut. The motor 8 is vertically mounted and connected to the tank cover 5 via a flange. The end of the inner frame 9 is riveted to the outer surface of the output end of the motor 8, and the filter shell 10 is threaded to the shell bottom 11. The outer ends of the injection pipe 13, the first nozzle 14, and the second nozzle 15 are all connected to a liquid pump; the first nozzle 14 and the second nozzle 15 are high-pressure types.

[0026] Example 2: The core function of this device is to achieve solid-liquid separation based on the centrifugal force generated by high-speed rotation. During the filtration process, the 5-bromo-2-chlorobenzoic acid mixture to be filtered is injected into the filter shell 10 through the injection pipe 13. The motor 8 drives the inner frame 9 to rotate, thereby causing the filter shell 10 to rotate at high speed. Under the action of centrifugal force, the liquid is thrown outward through the filter holes on the filter shell 10 and the bottom 11, while the solid particles are trapped inside the filter shell 10, completing the solid-liquid separation.

[0027] This device features a self-cleaning structure, enabling the filter housing 10 to self-clean even when it is empty inside the tank 2. The process is as follows: First, the injection pipe 13 injects cleaning fluid into the filter housing 10. The motor 8 operates, causing the filter housing 10 to rotate at high speed, and the cleaning fluid passes through the filter holes and is discharged, thus performing initial cleaning of the filter holes. Subsequently, the first nozzle 14 and the second nozzle 15 operate. The first nozzle 14 sprays directly onto the inner wall of the filter housing 10, and the second nozzle 15 sprays directly onto the outer wall of the filter housing 10. The sprayed jets wash the surfaces, while the motor 8 continues to operate, driving the filter housing 10 to rotate, achieving effective self-cleaning of the filtration mechanism.

[0028] The working principle of this utility model is as follows: Check that all components of the device are intact, ensuring that the bracket 1 is securely welded to the tank 2, and that the tank 2 is made of stainless steel to guarantee the stability and corrosion resistance of the device. Confirm that the bayonet 6 is circumferentially aligned with the axis of the tank cover 5, and that the fastener 7 is a ring nut for easy subsequent fixing of the tank cover 5. Check that the motor 8 is vertically mounted and reliably connected to the tank cover 5 via a flange, that the end of the inner frame 9 is riveted to the outer surface of the output end of the motor 8, and that the filter shell 10 is tightly threaded to the bottom shell 11. Simultaneously, ensure that the outer ends of the injection pipe 13, the first nozzle 14, and the second nozzle 15 are all connected to liquid pumps, and that the first nozzle 14 and the second nozzle 15 are high-pressure type, and that the integrated electronic valves on the injection pipe 13, the first nozzle 14, and the second nozzle 15 are functioning properly.

[0029] Prepare the 5-bromo-2-chlorobenzoic acid mixture to be filtered. Open the electrically controlled valve on the injection pipe 13 and inject the mixture into the filter shell 10 via the liquid pump. After injection, close the electrically controlled valve on the injection pipe 13. Start the motor 8, which drives the inner frame 9 to rotate, thereby causing the filter shell 10 to rotate at high speed. Under the action of centrifugal force, the liquid is thrown outward through the filter holes on the filter shell 10 and the bottom 11, and discharged through the outlet pipe 12 at the bottom of the tank 2, while solid particles are trapped inside the filter shell 10. When the liquid discharged from the outlet pipe 12 is relatively clear and the amount of solid particles inside the filter shell 10 no longer increases significantly, it indicates that filtration is complete, and the motor 8 is turned off.

[0030] Open the electrically controlled valve on the injection pipe 13, and inject the cleaning solution into the filter housing 10 through the injection pipe 13 using the liquid pump. After injecting an appropriate amount of cleaning solution, close the electrically controlled valve on the injection pipe 13. Start the motor 8 to make the filter housing 10 rotate at high speed. The cleaning solution passes through the filter holes and is discharged under the action of centrifugal force, performing preliminary cleaning of the filter holes. After cleaning for a period of time, turn off the motor 8. Next, open the electrically controlled valves on the first nozzle 14 and the second nozzle 15, and use the liquid pump to spray high-pressure cleaning solution from the first nozzle 14 and the second nozzle 15 respectively. The first nozzle 14 sprays directly onto the inner wall of the filter housing 10, and the second nozzle 15 sprays directly onto the outer wall of the filter housing 10. At the same time, start the motor 8 again to make the filter housing 10 rotate, allowing the jet to fully rinse the inner and outer surfaces of the filter housing 10. After cleaning is completed, close the electrically controlled valves on the motor 8, the first nozzle 14, and the second nozzle 15 to complete the self-cleaning process.

[0031] Compared with the prior art, the present invention has the following advantages: This rapid filtration device for 5-bromo-2-chlorobenzoic acid utilizes centrifugal force generated by high-speed rotation to achieve solid-liquid separation. Compared with traditional filtration methods, it can separate solid particles and liquid in a 5-bromo-2-chlorobenzoic acid mixture more quickly, greatly improving filtration efficiency and saving filtration time. It is suitable for large-scale production scenarios with high requirements for filtration speed.

[0032] The device is equipped with a self-cleaning structure that allows for a thorough cleaning of the filtration mechanism after filtration. Cleaning solution is injected through the injection pipe 13, and the high-speed rotation of the filter housing 10 forces the solution through the filter holes for initial cleaning. Then, the first nozzle 14 and the second nozzle 15 provide high-pressure rinsing of the inner and outer walls of the filter housing 10, while the rotation of the filter housing 10 further enhances the self-cleaning of the filtration mechanism. This function effectively prevents filter hole clogging and residual impurities on the filter housing surface, ensuring the effectiveness and quality of each filtration, reducing manual cleaning workload and costs, and extending the device's lifespan.
