Abstract
Description
Technical Field
[0001] This utility model relates to a sodium hydroxide dosing device for erythromycin fermentation, and belongs to the technical field of sodium hydroxide dosing devices. Background Technology
[0002] Midecamycin is a macrolide antibiotic produced by Streptomyces. It is mainly effective against Gram-positive bacteria and Gram-negative bacteria such as meningococci and gonococci. Its indications include respiratory tract infections caused by Staphylococcus aureus, hemolytic streptococci, and pneumococci, as well as skin, soft tissue, and biliary tract infections. It can also be used for mycoplasma pneumonia.
[0003] When producing midecamycin through fermentation in a reactor, sodium hydroxide needs to be added, thus requiring a dispensing device. However, due to varying production volumes, different sizes and types of fermentation reactors are used. Traditional dispensing devices are typically designed to be synchronized with the inlet height of the fermentation reactor, resulting in a relatively fixed height. Consequently, the overall height of the dispensing device cannot be freely adjusted according to the inlet height of different sized fermentation reactors, leading to low flexibility in its use and making it inconvenient for operators.
[0004] To address this, a sodium hydroxide dosing device for erythromycin fermentation is proposed. Utility Model Content
[0005] In view of this, the present invention provides a sodium hydroxide dosing device for erythromycin fermentation to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.
[0006] The technical solution of this utility model is implemented as follows: A sodium hydroxide dosing device for erythromycin fermentation includes a box body. An installation plate is provided on the front side of the box body. A storage tank is fixedly installed on the top left side of the installation plate. The inner cavity of the storage tank is connected to a discharge pipe. A suction valve is fixedly installed on the bottom of the installation plate. The end of the discharge pipe away from the storage tank is connected to the input end of the suction valve. An adjustment mechanism is provided on the surface of the box body. The adjustment mechanism includes a servo motor, a drive bevel gear, and lead screws. The servo motor is located on the left side of the box body. The three lead screws are movably connected to the rear side of the inner cavity of the box body. The surfaces of the three lead screws are threaded with screw blocks. The tops of the three screw blocks are fixedly installed with clamping rods. The inner sides of the three clamping rods are movably connected with connecting rods. The other ends of the three connecting rods are movably connected with clamping blocks. An installation frame is fixedly installed on the front side of the top of the box body. The three clamping blocks are slidably connected to the inner sides of the three installation frames. The front sides of the three clamping blocks are fixedly installed on the rear side of the installation plate.
[0007] More preferably, all three driving bevel gears are located on the rear side of the housing, and each of the rear sides of the housing is movably connected to a driven bevel gear. The surfaces of the three driving bevel gears mesh with the surfaces of the three driven bevel gears, and the front sides of the three driven bevel gears are fixedly connected to the rear sides of the three lead screws.
[0008] More preferably, the servo motor is fixedly installed on the left side of the housing surface, and the output end of the servo motor is fixedly connected to a mounting rod, with all three active bevel gears fixedly installed on the surface of the mounting rod.
[0009] More preferably, each of the tops of the housing is provided with a movable groove, and the three clamping rods pass through the inner cavities of the three movable grooves and extend to the top of the housing.
[0010] More preferably, a limiting rod is fixedly installed on the rear side of the inner cavity of the box, and the inner surfaces of the three screw blocks are slidably connected to the surfaces of the three limiting rods.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:
[0015] I. This utility model, through the setting of an adjustment mechanism, uses the output of a servo motor to drive the lead screw to move the clamping rod to the rear. At this time, the connecting rod swings due to the movement of the clamping rod, pushing the clamping block and the mounting plate to move downward. Simultaneously, the mounting plate drives the storage tank, the discharge pipe and the extraction valve to move, so that the extraction valve can feed into the inlet of fermentation reactors of different heights, improving the flexibility and convenience of equipment use and making it easier for operators to use.

[0027] Example 1
[0028] like Figure 1-5As shown, this utility model embodiment provides a sodium hydroxide dosing device for erythromycin fermentation, including a housing 1. A mounting plate 3 is provided on the front side of the housing 1. A storage tank 4 is fixedly installed on the top left side of the mounting plate 3. A discharge pipe 5 is connected to the inner cavity of the storage tank 4. A suction valve 6 is fixedly installed at the bottom of the mounting plate 3. The end of the discharge pipe 5 away from the storage tank 4 is connected to the input end of the suction valve 6. An adjustment mechanism 2 is provided on the surface of the housing 1. The adjustment mechanism 2 includes a servo motor 201, a drive bevel gear 203, and a lead screw 205. The servo motor 201 is located on the left side of the housing 1. Three lead screws 205 are movably connected to the rear side of the inner cavity of the housing 1. Each of the three lead screws 205 has a threaded connection to a screw block 206. A clamping rod 207 is fixedly mounted on the top of each of the three screw blocks 206. A connecting rod 208 is movably connected to the inner side of each of the three clamping rods 207. A clamping block 209 is movably connected to the other end of each of the three connecting rods 208. A mounting bracket 210 is fixedly mounted on the front side of the top of the housing 1. The three clamping blocks 209 are slidably connected to the inner side of the three mounting brackets 210. The front sides of the clamping blocks 209 are all fixedly installed on the rear side of the mounting plate 3. Three driving bevel gears 203 are all located on the rear side of the housing 1. Driven bevel gears 204 are movably connected to the rear side of the housing 1. The surfaces of the three driving bevel gears 203 mesh with the surfaces of the three driven bevel gears 204. The front sides of the three driven bevel gears 204 are all fixedly connected to the rear side of the three lead screws 205. The servo motor 201 is fixedly installed on the left side of the housing 1. The output end of the servo motor 201 is fixedly connected to the mounting rod 202. Each active bevel gear 203 is fixedly installed on the surface of the mounting rod 202. Each of the tops of the housing 1 has a moving groove 211. Each of the three clamping rods 207 passes through the inner cavity of the three moving grooves 211 and extends to the top of the housing 1. Each of the three inner cavities of the housing 1 has a limiting rod 212 fixedly installed on the rear side. Each of the three screw blocks 206 has its inner surface slidably connected to the surface of the three limiting rods 212. Each of the mounting rods 202 has a support block 213 movably connected to its surface through a bearing. The front sides of the three support blocks 213 are fixedly installed on the rear side of the housing 1.
[0029] By setting the adjustment mechanism 2, through the output of the servo motor 201, the lead screw 205 drives the clamping rod 207 to move backward. At this time, the connecting rod 208 swings due to the movement of the clamping rod 207, pushing the clamping block 209 and the mounting plate 3 downward. At this time, the mounting plate 3 simultaneously drives the storage tank 4, the discharge pipe 5 and the extraction valve 6 to move, so that the extraction valve 6 can feed into the inlet of the fermentation reactor at different heights, improving the flexibility and convenience of equipment use, and making it easier for operators to use. By setting the moving slot 211 The movement of the clamping rod 207 can be limited to prevent it from shifting and affecting the lifting and adjustment of the mounting plate 3 and its surface components. The movement of the screw block 206 can be limited by the limiting rod 212 to prevent it from rotating synchronously with the lead screw 205, which would affect the lifting and adjustment of the mounting plate 3 and its surface components. The support block 213 can support the mounting rod 202 to prevent it from falling off after long-term use.
[0030] Example 2
[0031] like Figure 1 As shown, in one embodiment, anchor bolts 9 are threadedly connected to both the left and right sides of the surface of the box 1, and the bottoms of the four anchor bolts 9 are threadedly connected to the ground. A scale 8 is fixedly installed on the front side of the storage tank 4, and a solid flow meter 7 is fixedly installed on the top of the discharge pipe 5.
[0032] By setting anchor bolts 9, the overall equipment can be stabilized, preventing the equipment from tipping over due to accidental collisions caused by external factors. By setting scale gauges 8 and solid flow meters 7, the remaining material in the storage tank 4 and the amount of material injected into the reaction vessel can be easily displayed, improving the ease of use of the equipment.
[0033] In operation, the entire device is positioned close to the fermentation apparatus, ensuring that the discharge port at the bottom of the extraction valve 6 is perpendicular to the feed port of the fermentation apparatus. Through the output of the servo motor 201, the mounting rod 202 drives the active bevel gear 203 to rotate. At this time, the active bevel gear 203 and the driven bevel gear 204 engage, causing the lead screw 205 to rotate synchronously. Consequently, the screw block 206 moves backward along the threaded surface of the lead screw 205 due to the rotation of the lead screw 205, and simultaneously drives the clamping rod 207 to move synchronously. The device moves backward, causing the connecting rod 208 to swing and pull the clamping block 209 downward. The mounting plate 3 follows the clamping block 209 and moves the storage tank 4, discharge pipe 5, and extraction valve 6 downward synchronously. The discharge port connected to the output end of the extraction valve 6 is connected to the inlet of the fermentation device. Then, through the output of the extraction valve 6, the extraction valve 6 generates suction and extracts the sodium hydroxide in the storage tank 4 through the discharge pipe 5, and injects it into the interior of the fermentation device through the output end of the extraction valve 6, thus completing the addition of sodium hydroxide.
[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
