Description

Technical Field

[0001] This utility model relates to the field of aeration filter technology, specifically to an anti-clogging aeration filter structure for fermenters. Background Technology

[0002] A fermenter is an industrial device used for microbial fermentation. Its main body is typically a cylindrical column made of stainless steel. It is designed to withstand steam sterilization, offers some operational flexibility, minimizes internal attachments (to avoid dead zones), has strong material and energy transfer capabilities, and allows for adjustments to facilitate cleaning and reduce contamination. It is suitable for the production of various products and reduces energy consumption. Aeration filter discs are used in fermenter applications. These discs are industrial filtration components made with multi-layered sintered stainless steel mesh or woven metal mesh as the core material. This tool uses a vacuum sintering process to composite multiple layers of metal mesh into a single structure, possessing technical characteristics such as uniform pore distribution, high pressure resistance (withstanding a maximum working pressure of 5MPa), and a wide temperature range (-200℃ to 500℃).

[0003] In existing ventilation filter disc structures, the filter media is easily clogged by substances produced during fermentation after prolonged use. For example, large molecules such as proteins and polysaccharides in the fermentation broth may be adsorbed onto the filter disc, gradually reducing the effective filtration area of ​​the filter disc. This not only reduces the filtration efficiency of the ventilation filter disc but also increases the ventilation resistance. Utility Model Content

[0004] This invention proposes an anti-clogging aeration filter disc structure for fermenters, which solves the problem that the filter medium in the existing aeration filter disc structure is easily clogged after long-term use, affecting the filtration efficiency of the aeration filter disc and increasing the aeration resistance of the filter disc.

[0005] The technical solution of this utility model is as follows: A clog-resistant aeration filter disc structure for a fermenter includes a shell, with mounting disc frames on both sides of the shell. Multiple aeration filter layers are arranged inside the mounting disc frames. The structure also includes square strips, a first aeration disc, a tapping mechanism, a rotating shaft, a second aeration disc, a cleaning brush, and an opposing moving mechanism. Multiple square strips are installed on both sides of the inner wall of the shell. The first aeration disc is sleeved on each square strip and can move along the square strips. The tapping mechanism is installed on the outer side of the first aeration disc on one of the two sides. The mounting plate bracket, located on the outside during installation, is used for striking. The rotating shaft is rotatably mounted on the outside of the first vent plate on the other side of the two sides and moves synchronously with the first vent plate. The first vent plate is provided with a driving component for driving the rotating shaft to rotate. The second vent plate is mounted on the rotating shaft and rotates synchronously with the rotating shaft. The cleaning brush is provided on the second vent plate. The opposing moving mechanism is located in the middle of the inner wall of the housing. The two first vent plates can move towards each other along the square strip under the drive of the opposing moving mechanism.

[0006] The opposing moving mechanism includes a mounting base, a drive shaft, a deflection plate, and a transmission component. Two mounting bases are installed in the middle of the inner wall of the housing, and the two mounting bases are symmetrically arranged. The drive shaft is rotatably mounted on the inner side of the mounting base. A driving component for driving the drive shaft to rotate is provided on one of the mounting bases on one of the two sides. The deflection plate is installed on the inner end of the drive shaft and can deflect around the drive shaft. The inner side of the deflection plate is connected to the inner side of the first vent plate through two sets of transmission components.

[0007] As a preferred embodiment of the anti-clogging venting filter disc structure for a fermenter described in this utility model, in order to realize the transmission between the deflection plate and the first venting disc, the transmission component includes a T-shaped connecting seat, an L-shaped connecting seat and a connecting plate. The connecting plate is sleeved on the T-shaped connecting seat and the L-shaped connecting seat. The outer end of the T-shaped connecting seat is connected to the inner side of the deflection plate, and the outer end of the L-shaped connecting seat is connected to the inner side of the first venting disc.

[0008] The striking mechanism includes a cylinder, a limiting rod, a striking seat, and a spring. The cylinder is installed on the outside of the first vent plate and moves synchronously with the first vent plate. The limiting rod is installed in the middle of the inner wall of the cylinder. The striking seat is sleeved on the limiting rod and can move along the limiting rod. The spring is sleeved on the limiting rod, and the two ends of the spring are respectively connected to the cylinder and the striking seat.

[0009] As a preferred embodiment of the anti-clogging venting filter disc structure for a fermenter described in this utility model, in order to avoid direct collision between the striking seat and the mounting plate frame and extend the overall service life of the device, a buffer pad is provided on the side of the striking seat located outside the cylinder.

[0010] As a preferred embodiment of the anti-clogging aeration filter disc structure for a fermenter described in this utility model, in order to enhance the cleaning effect on the aeration filter layer and enhance the anti-clogging effect of the aeration filter layer, the number of cleaning brushes is multiple, and the multiple cleaning brushes are arranged in a ring and disposed on the side of the second aeration disc close to the aeration filter layer.

[0011] The working principle and beneficial effects of this utility model are as follows:

[0012] In this invention, the cooperation between the rotating shaft, the second ventilation disc, and the cleaning brush enables the cleaning of impurities on the ventilation filter layer installed inside the fermenter, reducing the probability of impurities clogging the ventilation filter layer and ensuring the filtration and ventilation effects of the ventilation filter layer.

[0013] The first venting disc, the tapping mechanism, the rotating shaft, the second venting disc, the cleaning brush, and the opposing movement mechanism enable the cleaning brush and the tapping mechanism to move in opposite directions. This allows the tapping mechanism to repeatedly tap the mounting plate on the other side while the cleaning brush is cleaning the air filter layer on one side, causing the air filter layer on the other side to shake. This achieves simultaneous cleaning of impurities on the air filter layers on both sides, enhancing the cleaning effect on the air filter layer and improving the anti-clogging effect of the air filter disc structure.

[0014] Compared to existing technologies where the filter media in the aeration filter disc structure is prone to clogging after prolonged use, affecting the filtration efficiency and increasing the airflow resistance, this anti-clogging aeration filter disc structure for fermenters can simultaneously clean the filter media inside and outside the fermenter. This reduces the time impurities remain on the filter media, lowers the probability of clogging, and provides excellent filtration and smooth airflow. Attached Figure Description

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] like Figures 1-4 As shown, this embodiment proposes an anti-clogging aeration filter disc structure for a fermenter, including a housing 1, with mounting brackets 2 on both sides of the housing 1. Multiple aeration filter layers 3 are arranged inside the mounting brackets 2. It also includes a square strip 4, a first aeration disc 5, a tapping mechanism, a rotating shaft 6, a second aeration disc 7, a cleaning brush 8, and a counter-moving mechanism. Compared to existing aeration filter disc structures where the filter media is easily clogged after prolonged use, affecting the filtration efficiency and increasing the aeration resistance, this embodiment addresses this issue by using the cooperation between the rotating shaft 6, the second aeration disc 7, and the cleaning brush 8 to remove impurities from the aeration filter layers 3 installed inside the fermenter. The cleaning process reduces the probability of impurities clogging the ventilation filter layer 3, ensuring the filtration and ventilation effects of the ventilation filter layer 3. Through the first ventilation disc 5, the tapping mechanism, the rotating shaft 6, the second ventilation disc 7, the cleaning brush 8, and the opposing movement mechanism, the opposing movement of the cleaning brush 8 and the tapping mechanism is realized. This allows the tapping mechanism to repeatedly tap the mounting plate 2 on the other side while the cleaning brush 8 is cleaning the ventilation filter layer 3 on one side, causing the ventilation filter layer 3 on the other side to shake. This achieves simultaneous cleaning of impurities on the ventilation filter layers 3 on both sides, enhancing the cleaning effect on the ventilation filter layer 3 and improving the anti-clogging effect of the ventilation filter disc structure.

[0025] like Figure 2As shown, multiple square strips 4 are installed on both sides of the inner wall of the shell 1. A first venting disc 5 is sleeved on each square strip 4. A striking mechanism is installed on the outer side of the first venting disc 5 on one of the two sides. A rotating shaft 6 is rotatably installed on the outer side of the first venting disc 5 on the other side of the two sides. A driving component for driving the rotating shaft 6 is provided on the first venting disc 5; the driving component is a forward and reverse rotating motor. A second venting disc 7 is installed on the rotating shaft 6. Multiple cleaning brushes 8 are arranged in a ring on the second venting disc 7 near the aeration filter layer 3. These multiple cleaning brushes 8 simultaneously clean the aeration filter layer 3 inside the fermenter, enhancing the cleaning effect on impurities remaining on the aeration filter layer 3 and improving the anti-clogging effect of the aeration filter disc. An opposing moving mechanism is located in the middle of the inner wall of the shell 1. Figure 3 As shown, the opposing movement mechanism includes a mounting base 101, a drive shaft 102, a deflection plate 103, and a transmission component 104. Two mounting bases 101 are installed in the middle of the inner wall of the housing 1, and the two mounting bases 101 are symmetrically arranged. The drive shaft 102 is rotatably mounted on the inner side of the mounting base 101. A driving component for driving the drive shaft 102 to rotate is provided on one of the mounting bases 101 on each side. The driving component is a reciprocating motor. The deflection plate 103 is installed on the inner end of the drive shaft 102. The inner side of the deflection plate 103 is connected to the inner side of the first vent plate 5 via two sets of transmission components 104. Each transmission component 104 includes a T-shaped connecting seat, an L-shaped connecting seat, and a connecting plate. The connecting plate is sleeved on the T-shaped and L-shaped connecting seats. The outer end of the T-shaped connecting seat is connected to the inner side of the deflection plate 103, and the outer end of the L-shaped connecting seat is connected to the inner side of the first vent plate 5. When the deflection plate 103 deflects, it can drive the two first vent plates 5 to move in opposite directions via the transmission components 104. Figure 4 As shown, the striking mechanism includes a cylinder 201, a limiting rod 202, a striking seat 203, and a spring 204. The cylinder 201 is installed on the outside of the first vent plate 5, the limiting rod 202 is installed in the middle of the inner wall of the cylinder 201, the striking seat 203 is sleeved on the limiting rod 202, and the spring 204 is sleeved on the limiting rod 202. The two ends of the spring 204 are respectively connected to the cylinder 201 and the striking seat 203. A buffer pad is provided on the side of the striking seat 203 outside the cylinder 201. The buffer pad can buffer the striking seat 203 and the mounting plate 2, avoiding direct collision between the striking seat 203 and the mounting plate 2, thereby extending the overall service life of the device.

[0026] Working principle:

[0027] During the use of the aeration filter disc, the forward and reverse motors and the reciprocating motor are in the normally open state. The forward and reverse motors drive the rotating shaft 6 to rotate, the rotating shaft 6 drives the second aeration disc 7 to rotate, the second aeration disc 7 drives the cleaning brush 8 to rotate, and the reciprocating motor drives the transmission shaft 102 to rotate back and forth. The transmission shaft 102 drives the deflection plate 103 to deflect back and forth. The deflection plate 103 drives the first aeration discs 5 located on both sides to move back and forth along the square strip 4 through the transmission component 104. The first aeration discs 5 located on both sides simultaneously drive the cleaning brush 8 and the tapping mechanism to move back and forth in opposite directions. During the movement of the cleaning brush 8 and the tapping mechanism, the cleaning brush 8 cleans the impurities remaining on the aeration filter layer 3 located inside the fermenter. During the movement of the tapping mechanism, the mounting plate 2 located outside the fermenter is repeatedly tapped. After the mounting plate 2 is tapped, the aeration filter layer 3 on the mounting plate 2 shakes, realizing the shaking off of the impurities remaining on the aeration filter layer 3, thereby realizing the synchronous cleaning of impurities on the aeration filter layers 3 on both sides.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
