Description

Technical Field

[0001] This invention relates to the field of chemical equipment, and specifically to a pneumatic hammer vibration filtration reactor. Background Technology

[0002] Immobilized enzymes are enzymes artificially fixed on a carrier, existing in a closed state within a defined space, allowing for continuous reaction. The enzyme can then be recovered and reused. Compared to free enzymes, immobilized enzymes retain their catalytic properties while overcoming their limitations, offering advantages such as high stability, low environmental sensitivity, reusability or continuous use, easy separation from reaction products, and suitability for multi-enzyme reactions. Currently, significant progress has been made in the theoretical and applied research of immobilized enzymes, leading to their widespread application in the food, pharmaceutical, and chemical industries.

[0003] In traditional processes, after the immobilized enzyme completes its reaction in a reactor (a sealed reaction vessel), the reaction product and enzyme carrier particles need to be transported to a filter for separation. The separated enzyme carrier particles are then returned to the reactor for the next batch of reaction. In traditional equipment, the reactor and filter are separate devices. When these devices are located far apart, manual handling is very inconvenient, and the transfer process may also cause contamination of the filtered material. To overcome this problem, some equipment manufacturers have combined the filter and reactor functions into one, installing a filtration device, such as a filter screen, inside the reactor. However, with prolonged use, the filter pores on the screen are prone to clogging. Cleaning the filter screen installed inside the reactor through frequent disassembly and washing is inconvenient and can affect the reactor's sealing performance.

[0004] Patent CN209348625U discloses an apparatus for preparing lye oil. It includes a stirrer inside a reaction tank, a filter screen below the stirrer, and a vibrator at the bottom of the filter screen. The vibration of the vibrator causes the product to pass through the filter screen into the discharge chamber, preventing clogging of the filter screen. However, the vibrator in this patent is entirely located inside the reaction tank and requires electric drive, which is inconvenient for maintenance and affects its operational safety and service life. Summary of the Invention

[0005] This invention discloses a pneumatic hammer vibration filtration reactor. A filtration device is installed inside the reactor, and the main body of the pneumatic hammer vibration device is located outside the reactor. The iron core of the pneumatic hammer vibration device extends into the reactor and is installed at the bottom of the filtration device in a flexible connection manner. This facilitates the disassembly and maintenance of the pneumatic hammer vibration device and avoids the problem of wear caused by rigid contact between the pneumatic hammer and the filtration device during vibration, as well as the problem of affecting the sealing of the reactor.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A pneumatic hammer vibration filtration reactor includes a reactor body, a stirring device and a filtering device disposed inside the reactor body, and a pneumatic hammer vibration device disposed at the bottom of the reactor body. The pneumatic hammer vibration device includes a pneumatic hammer, an iron core connected to the top of the pneumatic hammer, and a sleeve sleeved outside the iron core. The sleeve is provided with an upper sleeve flange and a lower sleeve flange that are fixedly connected in a detachable manner. The bottom of the upper sleeve is open and the top surface is closed. The top surface of the upper sleeve is fixed to the bottom of the filtering device, and the bottom surface of the upper sleeve is fixed to the upper sleeve flange.

A portion of the upper sleeve and the iron core extend into the reactor body. The upper sleeve flange, the lower sleeve flange, the lower sleeve, and the pneumatic hammer are all located outside the reactor body. An expansion joint is provided on the upper sleeve extending into the reactor body, and the connection between the upper sleeve and the reactor body is sealed and fixed.

[0008] Furthermore, a discharge port and a discharge pipe are respectively opened on the bottom surface of the main body of the reactor. The discharge pipe is inserted into the discharge pipe, and a through hole is opened on the filter device. The top of the discharge pipe passes through the through hole, and there is a gap between the outer wall of the discharge pipe and the inner wall of the through hole.

[0009] Furthermore, a flange is provided circumferentially at the top of the discharge pipe, and the flange is located on the upper part of the filter device to limit the discharge pipe.

[0010] Furthermore, the filtering device includes an upper flange, an upper pressure ring, a filter screen, a second support rib, a lower flange, and a lower pressure ring. The filter screen is laid on the top surface of the second support rib. Circular holes are symmetrically opened on the filter screen and the second support rib. The upper flange and the lower flange are arranged on both sides of the filter screen and are fixedly connected to each other to form a clamping effect on the edge of the filter screen.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] This embodiment discloses a pneumatic hammer vibration filtration reactor, such as... Figures 1 to 8 As shown, it includes a reactor body 1, a stirring device 2 and a filtering device 4 disposed inside the reactor body 1, and a pneumatic hammer vibration device 3 disposed at the bottom of the reactor body 1 and partially exposed outside the reactor body 1.

[0029] The reactor body 1 is a sealed structure, comprising a cylindrical body 11, an upper end cap 17 sealing the upper opening of the cylindrical body 11, and a lower end cap 16 sealing the lower opening of the cylindrical body 11. The outer wall of the cylindrical body 11 is also provided with a first support rib 13 and an ear seat 12. The cylindrical body 11 is mounted on a cylindrical body flange 14, and the lower end cap 16 is fixed to an end cap flange 15. A discharge port and a discharge pipe are provided at the bottom of the lower end cap 16, with a discharge pipe 161 inserted into the discharge pipe. The discharge port is used to discharge the reaction products from the lower part of the filtration device 4, and the discharge pipe 161 is used to remove enzyme carrier particles intercepted on the filtration device 4 from the reactor.

[0030] The stirring device 2 includes a motor 21, a motor bracket 22, a stirring shaft 23, and a stirring paddle 24. The motor bracket 22 is installed on the top of the upper end cap 17. The motor 21 is fixedly installed on the motor bracket 22. The stirring shaft 23 extends into the interior of the reactor body 1. The stirring shaft 23 is connected to the output shaft of the motor 21 through a coupling. The stirring paddle 24 is fixed at the lower end of the stirring shaft 23 and located inside the reactor body 1.

[0031] The filter device 4 includes an upper flange 43, an upper pressure ring 44, a filter screen 41, a second support rib 42, a lower flange 45, and a lower pressure ring 46. The filter screen 41 has a mesh structure and is laid on the top surface of the second support rib 42. Circular holes are symmetrically opened at the center of the filter screen 41 and the second support rib 42. The upper flange 43 and the lower flange 45 are arranged on both sides of the filter screen 41 and are fixedly connected to each other to clamp and fix the edge of the filter screen 41. The upper pressure ring 44 and the lower pressure ring 46 are also arranged on both sides of the filter screen 41 and are located at the central circular hole. The upper pressure ring 44 and the lower pressure ring 46 are fixed to each other to clamp and fix the filter screen 41 at the edge of the circular hole.

[0032] The filter screen 41 in the above-mentioned filter device 4 is made of 316L sintered mesh, and the second support rib 42 is made of stainless steel. The second support rib 42 includes a support plate with the same center and a hexagonal annular main rib. A circular hole is opened in the center of the support plate, and multiple connecting ribs are arranged along the circumference of the support plate to connect the support plate and the annular main rib. Multiple reinforcing ribs are arranged along the circumference on the outside of the annular main rib. One end of the reinforcing rib is connected to the annular main rib, and the other end of the reinforcing rib can be fixed by the upper flange 43 of the filter screen and the lower flange 45 of the filter screen.

[0033] The air hammer vibration device 3 includes an air hammer 31 and an iron core 32 fixedly connected to the center of the base at the top of the air hammer 31. The vibration of the air hammer 31 drives the iron core 32 to generate an impact force, which is then transmitted to the filter device 4, causing the filter device 4 to vibrate and preventing the mesh of the filter screen 41 from becoming clogged. Since the reactor body 1 of this invention has a sealed structure, to avoid affecting the sealing performance and to facilitate the maintenance and replacement of the air hammer vibration device 3, the main body of the air hammer vibration device 3 is installed outside the reactor body 1, while a portion of the iron core 32 extends into the interior of the reactor body 1. To prevent the gap between the reactor body 1 and the iron core 32 from becoming loose during the up-and-down impact vibration process, a sleeve 33 is fitted over the iron core 32. The upper half of the sleeve 33 and the upper half of the iron core 32 extend into the interior of the reactor body 1. The top surface of the sleeve 33 is closed and fixed to the bottom of the filter device 4. The inner wall of the top surface of the sleeve 33 is in contact with but not fixedly connected to the top surface of the iron core 32. The bottom of the sleeve 33 is sealed and fixed to the top of the air hammer 31. The connection between the sleeve 33 and the reactor body 1 is sealed and fixed.

[0034] Specifically, such as Figure 6As shown, the sleeve 33 exposed outside the reactor body 1 is provided with a sleeve flange, which divides the sleeve 33 into an internally connected upper sleeve and a lower sleeve. The sleeve flange is further divided into a detachable upper sleeve flange 333 and a lower sleeve flange 332. The bottom of the upper sleeve is fixedly connected to the upper sleeve flange 333 and the connection is sealed. The top of the lower sleeve is fixedly connected to the lower sleeve flange 332 and the connection is sealed. The bottom of the lower sleeve is fixedly connected to the top of the air hammer 31 and the connection is sealed. An expansion joint 335 is provided on the sleeve 33 extending into the reactor body 1. That is, the sleeve 33, from top to bottom, includes a third straight pipe 336, an expansion joint 335, a second straight pipe 334, an upper sleeve flange 333, a lower sleeve flange 332, and a first straight pipe 331. Among them, the third straight pipe 336 and the second straight pipe 334 are the same straight pipe section that are internally connected, and the expansion joint 335 is a corrugated section. The first straight pipe 331 and the second straight pipe 334 are two independent straight pipe sections. They can be connected vertically by fitting and fixing the upper flange 333 and the lower flange 332 of the sleeve. Since the sleeve flange is located outside the reactor body 1, the upper flange 333 and the lower flange 332 of the sleeve can be disassembled and separated, and the air hammer 31 can be easily disassembled, replaced or repaired without affecting the sealing performance of the reactor body 1.

[0035] The top of the third straight pipe 336 is closed and fixed to the bottom surface of the annular main rib of the second support rib 42. The gap between the second straight pipe 334 and the reactor body 1 is fixedly sealed. The top of the iron core 32 is not fixedly connected to the third straight pipe 336. The iron core 32 directly applies the vibration impact force to the sleeve 33, which will not cause rigid impact wear to the filter device 4. Furthermore, due to the presence of the expansion joint 335 on the sleeve 33, the expansion joint 335 will continuously expand and contract with the vibration of the filter device 4 when the air hammer is working, thus avoiding the problem of rigid wear of the reactor and easy leakage caused by vibration.

[0036] To achieve better filtration and anti-clogging effects, multiple air hammer vibration devices 3 are arranged in a ring. In this embodiment, six air hammer vibration devices 3 are used, each fixedly installed on one side of the hexagonal annular main rib. The circumferential edge of the filter device 4 is not fixed to the inner wall of the reactor body 1. The filter device 4 is supported by the air hammer vibration devices 3, which can achieve a more ideal vibration filtration effect. A through hole is opened in the center of the filter device 4, and the top of the discharge pipe 161 passes through the through hole, such as... Figure 4As shown, a flange 151 is provided circumferentially at the top of the discharge pipe 161. The diameter of the flange 151 is larger than the diameter of the through hole, which serves to limit the discharge pipe 161. There is a small gap between the outer wall of the discharge pipe 161 and the inner wall of the through hole. When the filter device 4 vibrates, the discharge pipe 161 will not move with it, thus avoiding leakage at the connection gap between the discharge pipe 161 and the reactor body 1. The flange 151 also has a braking and limiting effect on the vibration of the filter device 4.

[0037] This invention integrates the stirring and filtering devices into a single design, reducing space requirements and manufacturing costs. Enzyme catalysis and separation can be performed within a single device, eliminating the need for repeated transport of immobilized enzymes between the reactor and filter, shortening the reaction cycle, improving production efficiency, and reducing enzyme carrier degradation. Furthermore, the invention applies a pneumatic hammer to the enzyme reactor, utilizing its strong impact force. By incorporating a pneumatic hammer vibration device 3, this impact force is transmitted to the filtering device 4, causing the filter screen 41 to vibrate, thereby clearing filter blockages and improving filtration efficiency. The invention also combines a sleeve 33 with an expansion joint 335 in a design integrated with the pneumatic hammer. When the pneumatic hammer 31 is not operating, the expansion joint 335 is compressed; when the pneumatic hammer 31 is operating, the expansion joint 335 extends with the vibration of the filtering device 4, solving the problems of rigid wear and leakage caused by device vibration.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
