Description

Technical Field

[0001] This invention relates to the field of filtration extraction equipment technology, specifically a filtration extraction equipment for L-cystine production. Background Technology

[0002] L-cysteine ​​is a sulfur-containing amino acid composed of two cysteine ​​molecules linked together. In the body, it participates in protein structure stability, promotes healthy hair, skin, and nails, and has antioxidant properties. The main raw materials for L-cysteine ​​production are natural hair-like substances rich in keratin, such as human hair, pig hair, wool, and feathers. Cystine is extracted from these keratin raw materials through an acid hydrolysis process. Industrially, concentrated hydrochloric acid is commonly used to hydrolyze hair at high temperatures, destroying the keratin structure. After purification through steps such as filtration, neutralization, and crystallization, the product cysteine ​​is obtained, which assists in skin formation. Filtration is one of the important steps in the preparation of cysteine.

[0003] A search revealed Chinese patent application number 201820790698.5, which discloses a high-efficiency filtration device for cystine preparation. The device includes a filtration chamber with a cover at its upper end and a feed inlet at the upper middle part of the cover. This invention utilizes a water wheel, blades, and a water tank to disperse and drop the filtrate, thus improving filtration efficiency. Furthermore, the inclusion of a vacuum filtration pump, a coarse filter plate, a cotton-like filter plate, and an ultrafiltration membrane further enhances filtration efficiency.

[0004] It is known that the above patent has the following shortcomings: In the process of cystine preparation, the acid hydrolyzed mixture needs to be filtered by traditional filtration equipment. However, the traditional filtration device has a single function. Although it can filter the acid hydrolyzed material, it is necessary to first use external equipment to perform acid hydrolysis on the keratin raw material, and then transfer the mixture obtained from acid hydrolysis into the filtration equipment for filtration. The material transfer process is cumbersome and reduces the overall work efficiency of cystine production.

[0005] To address the aforementioned issues, a filtration extraction device for L-cystine production is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a filtration and extraction device for L-cysteine ​​production. By using this device, the problem of filtering acid-hydrolyzed mixtures using traditional filtration equipment in the cysteine ​​preparation process in the prior art is solved. Traditional filtration equipment has a single function. Although it can filter the acid-hydrolyzed material, it requires first acid-hydrolyzing the keratin raw material through external equipment, and then transferring the mixture obtained from acid hydrolysis into the filtration equipment for filtration. The material transfer process is cumbersome and reduces the overall working efficiency of cysteine ​​production.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a filtration extraction device for L-cysteine ​​production, comprising a filtration assembly, a support frame fixedly connected to one side of the filtration assembly, a reaction assembly disposed on the top of the support frame, and a pulverizing assembly disposed on the upper end of the reaction assembly; a pump disposed between the filtration assembly and the reaction assembly; the reaction assembly includes a storage tank disposed above the support frame, the storage tank being interconnected with the input end of the pump, a mixing chamber fixedly connected to the top of the storage tank, a solenoid valve disposed in the center of the top surface of the storage tank, and a stirring rod assembly rotatably connected inside the mixing chamber; the pulverizing assembly includes a pulverizing chamber disposed on the top of the mixing chamber, a feeding hopper disposed at the bottom of the pulverizing chamber extending into the mixing chamber, a feed hopper disposed at the upper end of the pulverizing chamber, and an installation box disposed on one side of the pulverizing chamber; a liquid inlet pipe fixedly connected to the top of the mixing chamber, a feeding disc rotatably connected to the inner cavity of the mixing chamber, and a nozzle assembly evenly distributed around the outer periphery of the feeding disc.

[0008] The above-described structure integrates crushing, acidification reaction, and filtration extraction, eliminating the need for external equipment for raw material pretreatment, reaction, and filtration. This completely eliminates the cumbersome material transfer steps in traditional production, significantly shortens the production process, and improves the overall efficiency of L-cysteine ​​production. Simultaneously, the inlet pipe at the top of the mixing chamber, in conjunction with the feed tray equipped with nozzles, ensures the uniform introduction of concentrated hydrochloric acid into the mixing chamber, laying the structural foundation for sufficient contact between the raw materials and hydrochloric acid, and solving the problem of uneven hydrochloric acid distribution in traditional mixing methods.

[0009] Preferably, the reaction assembly further includes a protective box fixedly connected to the inside of the mixing chamber, a connecting pipe fixedly connected to one side of the feed tray, the connecting pipe being rotatably connected to one side of the liquid inlet pipe, and the connecting pipe communicating with the liquid inlet pipe.

[0010] The design of the above structure, with the rotating connection between the connecting pipe and the inlet pipe, ensures the stable delivery of concentrated hydrochloric acid from the inlet pipe to the feed tray without affecting the rotation of the feed tray, thus achieving functional compatibility between delivery and rotation. The protective box effectively protects the internal transmission components, preventing corrosive media such as hydrochloric acid in the mixing chamber from contacting the transmission structure, preventing corrosion and damage to the components, extending the service life of the device, and ensuring the stable operation of the transmission system.

[0011] Preferably, the protective box further includes a bevel gear three fixedly connected to the outer periphery of the connecting pipe, a bevel gear four meshing with one side of the bevel gear three, the bevel gear four being rotatably connected to the inside of the protective box, a drive box fixedly connected to one side of the mixing chamber, and a second motor fixedly connected to the top of the drive box.

[0012] The above-mentioned structural design, through the meshing of bevel gear three and bevel gear four, establishes a power transmission path from the second motor to the feed tray, enabling the second motor to provide stable power for the rotation of the feed tray. The drive box, as the mounting carrier of the second motor, not only realizes the fixed installation of the motor, but also protects the internal transmission components. The overall structure is compact, the power transmission is efficient, and it avoids the problem of excessive equipment size caused by setting up an additional power source.

[0013] Preferably, a rotating rod is rotatably connected inside the drive box, and the rotating rod is fixedly connected to the output end of the second motor. A second bevel gear is fixedly connected to the outer periphery of the rotating rod. There are two sets of the second bevel gears. One side of each set of the second bevel gears is meshed with a first bevel gear. One set of the first bevel gears is fixedly connected to the fourth bevel gear through a connecting rod. The other set of the first bevel gears is fixedly connected to the stirring rod assembly through a connecting column.

[0014] The design employs a single second motor driving dual actuators. Through the transmission and cooperation of the rotating rod, two sets of bevel gears, and two sets of bevel gears, the rotation and spraying of the feed tray and nozzle assembly, as well as the stirring action of the stirring rod assembly, are synchronously realized. This transmission structure eliminates the need for separate motors for stirring and spraying, simplifying the equipment structure, reducing energy consumption, and ensuring the synchronicity of spraying and stirring actions. This allows the hydrochloric acid spraying and raw material stirring to be coordinated in real time, further improving the mixing uniformity of the raw materials and hydrochloric acid and accelerating the acidification reaction rate.

[0015] Preferably, the filter assembly includes a filter chamber that is connected to the pump output end. A maintenance cover is snapped onto the top of the filter chamber, a collection hopper is provided at the bottom of the filter chamber, an installation plate is fixedly connected inside the filter chamber, and a filter cartridge assembly is provided on one side of the installation plate. The filter cartridge assembly consists of nine sets.

[0016] The design employs a split-flow filtration mode with nine filter cartridges, dispersing the acid hydrolysis mixture across multiple cartridges for simultaneous filtration. Compared to traditional single-cartridge filtration, this significantly increases the filtration area and efficiency, effectively preventing clogging issues caused by material concentration in a single cartridge. The inspection cover uses a snap-fit ​​connection, allowing staff to quickly open the filter chamber for maintenance, cleaning, or replacement of the internal filter cartridges. The collection hopper enables centralized collection of the L-cysteine-containing solution after filtration, preventing solution spillage and waste, and improving material recovery rate.

[0017] Preferably, each filter cartridge assembly includes a filter cartridge inlet disposed on the top surface of the filter chamber, a filter screen disposed at the lower end of the filter cartridge inlet, and a receiving plate fixedly connected to the bottom of the filter screen.

[0018] The design of the above-described structure guides the acid-hydrolyzed mixture precisely into the filter cartridge, preventing random diffusion within the filtration chamber and ensuring that all material passes through the filter screen. The filter screen, as the core filtration component, effectively traps solid impurities in the mixture, guaranteeing the purity of the filtrate. The bottom receiving plate supports the trapped solid impurities, preventing them from falling into the collection hopper and contaminating the filtrate. It also facilitates centralized removal of impurities during subsequent cleaning of the filter cartridge, improving maintenance convenience.

[0019] Preferably, the two sets of bevel gear one, the two sets of bevel gear two, and the rotating rod are all rotatably connected inside the drive box.

[0020] With the above-mentioned structural design, all transmission gears and rotating rods are built-in and rotatably connected inside the drive box. On the one hand, the drive box forms a closed protective space to prevent external dust, moisture or corrosive gases from contacting the gear components, reducing component wear and corrosion. On the other hand, the centralized rotating connection design makes the fit between transmission components more precise, reduces friction loss during transmission, ensures the stability and efficiency of power transmission, and extends the service life of the transmission system.

[0021] Preferably, a heat dissipation hole group is provided on one side of the mounting box, a first motor is fixedly connected inside the mounting box, a bevel gear five is fixedly connected to the output end of the first motor through a connecting rod, a bevel gear six is ​​meshed on one side of the bevel gear five, the bevel gear six is ​​rotatably connected inside the mounting box, and a first gear is fixedly connected to one side of the bevel gear six.

[0022] With the above-described structure, the heat dissipation holes on one side of the mounting box can dissipate the heat generated by the first motor during operation in a timely manner, preventing the motor from overheating and causing performance degradation or damage, thus ensuring stable operation of the motor over a long period of time. The first motor transmits power to the first gear through the meshing of bevel gear five and bevel gear six. The transmission structure is compact and highly efficient, providing sufficient power for the rotation of the subsequent crushing roller. At the same time, the mounting box provides fixation and protection for the internal motor and gear components, improving structural stability.

[0023] Preferably, the first gear is provided in two sets, and the two sets of the first gear are meshed together. The crushing chamber is rotatably connected with a crushing roller, and the crushing roller is provided in two sets, with the two sets of crushing rollers respectively fixedly connected to the two sets of the first gear.

[0024] With the above-mentioned structural design, the two sets of first gears mesh with each other, ensuring that the two sets of crushing rollers can rotate synchronously in opposite directions. This rotation method can form a shearing and squeezing effect on the raw materials entering the crushing chamber, greatly improving the crushing effect and crushing hair-like raw materials into finer particles, creating favorable conditions for subsequent full reaction with hydrochloric acid. The fixed connection between the crushing rollers and the first gears ensures the directness and stability of power transmission, avoiding slippage and misalignment during transmission, and ensuring the continuous and stable operation of the crushing process.

[0025] Preferably, a guide plate is provided above the two sets of crushing rollers, with one end of the guide plate located at the upper end between the two sets of crushing rollers, and the other end of the guide plate fixedly connected to the inside of the feed hopper.

[0026] The above-described structure, with its inclined installation of the guide plate, guides the raw materials entering from the hopper precisely to the working area between the two sets of crushing rollers. This prevents the raw materials from scattering into the corners of the crushing chamber and becoming uncrushable, thus improving material utilization and crushing efficiency. At the same time, the guide plate also slows down the falling speed of the raw materials, giving the crushing rollers more time to crush them, further ensuring the uniformity of the crushing effect and guaranteeing the full progress of the subsequent acidification reaction.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This utility model discloses a filtration extraction device for L-cystine production. In use, natural hair-like substances rich in keratin are used as raw materials and can be fed into the crushing chamber through the feed hopper. The first motor is turned on to drive two sets of crushing rollers to rotate, thereby crushing the raw materials. The crushed material enters the mixing chamber through the feed hopper. Crushing the raw materials helps the subsequent materials to be more fully mixed and reacted with hydrochloric acid. 2. While the pulverized material is being fed into the mixing chamber, the user can introduce concentrated hydrochloric acid into the mixing chamber through the inlet pipe. The concentrated hydrochloric acid is sprayed into the mixing chamber through the feed plate and multiple sets of nozzles. At this time, the second motor is turned on. The second motor drives the feed plate, multiple sets of nozzles and stirring rod assembly to rotate through multiple sets of bevel gears. The stirring rod assembly then fully stirs the pulverized raw material and hydrochloric acid. Under heating conditions, hydrolysis occurs, destroying the keratin structure and releasing cystine to form a hydrolyzed mixture, thereby improving the acidification reaction efficiency. 3. The rotational motion of the above-mentioned multiple sets of nozzles can disperse the originally concentrated hydrochloric acid into uniform droplets, which are then sprayed onto the crushed keratin material. This can increase the contact area between the concentrated hydrochloric acid solution and the raw material, further promote the acidification reaction, and make the reaction between the keratin material and hydrochloric acid more complete. 4. After the acidification reaction of the materials inside the mixing chamber is completed, the user can open the solenoid valve, and the mixture obtained from acid hydrolysis will enter the storage tank; at the same time, the pump will be turned on, and the mixture obtained from acid hydrolysis will enter the filtration chamber through the pipeline. After filtration by multiple sets of filter cartridges, the solution containing L-cysteine ​​will flow from the side of the filter screen into the collection hopper. The user can then collect the solution containing L-cysteine ​​and purify it by neutralization, crystallization and other steps to obtain the product cysteine. 5. The filter chamber is equipped with multiple filter cartridge assemblies, which can divert the mixture after acid hydrolysis and then filter it, which can improve the filtration efficiency of the device and prevent filter cartridge clogging. The filtered solid impurities remain inside the filter cartridge assembly and are supported by the receiving plate at the bottom of the filter cartridge. After the device has finished working, the inspection cover can be opened to clean the impurities inside the filter chamber. Attached Figure Description

The other set of first bevel gears 271 is fixedly connected to the stirring rod assembly 25 through a connecting column.

[0038] The filter assembly 3 includes a filter chamber 31, which is connected to the output end of the pump 41.

An installation plate is fixedly connected inside the filter chamber 31, and a filter cartridge assembly 34 is provided on one side of the installation plate. The filter cartridge assembly 34 has nine sets.

[0039] Each filter cartridge assembly 34 includes a filter cartridge inlet 341 disposed on the top surface of the filter chamber 31, a filter screen 342 disposed at the lower end of the filter cartridge inlet 341, and a receiving plate 343 fixedly connected to the bottom of the filter screen 342.

[0040] Two sets of bevel gears 271, two sets of bevel gears 272, and the rotating rod are all rotatably connected inside the drive box 27.

[0041] A heat dissipation hole group is provided on one side of the mounting box 14. A first motor 141 is fixedly connected inside the mounting box 14. A bevel gear 142 is fixedly connected to the output end of the first motor 141 through a connecting rod. A bevel gear 143 is meshed on one side of the bevel gear 142. The bevel gear 143 is rotatably connected inside the mounting box 14. A first gear 131 is fixedly connected to one side of the bevel gear 143.

[0042] Two sets of first gears 131 are provided, and the two sets of first gears 131 are meshed and connected. A crushing roller 132 is rotatably connected inside the crushing chamber 13. Two sets of crushing rollers 132 are provided, and the two sets of crushing rollers 132 are respectively fixedly connected to the two sets of first gears 131.

[0043] A guide plate 111 is provided above the two sets of crushing rollers 132. One end of the guide plate 111 is located at the upper end between the two sets of crushing rollers 132, and the other end of the guide plate 111 is fixedly connected to the inside of the feed hopper 11.

[0044] In summary, the working principle is as follows: When raw material crushing is required, natural hair-like raw materials rich in keratin are fed into the crushing chamber 13 through the feed hopper 11. The first motor 141 is turned on, and its output end drives the bevel gear 5 142 to rotate through the connecting rod. The bevel gear 5 142 meshes with the bevel gear 6 143, thereby driving the two sets of first gears 131 to rotate. The two sets of first gears 131 drive the corresponding crushing rollers 132 to rotate, thus crushing the raw material. The guide plate 111 can guide the raw material to fall between the two sets of crushing rollers 132, improving the crushing efficiency. The crushed material enters the subsequent process through the feed hopper 12.

[0045] The pulverized material enters the mixing chamber 21 through the feeding hopper 12 and enters the acidification and hydrolysis stage. At the same time, the user injects concentrated hydrochloric acid through the liquid inlet pipe 28. After flowing through the feeding disc 26, the concentrated hydrochloric acid is sprayed into the mixing chamber 21 through the nozzles evenly distributed on its outer periphery. The second motor 24 is turned on, and the rotating rod connected to its output end drives the bevel gear 272 to rotate. The bevel gear 272 meshes with the bevel gear 1 271. One set of bevel gear 1 271 drives the bevel gear 4 292 to rotate through the connecting rod. The bevel gear 4 292 meshes with the bevel gear 3 291, thereby driving the feeding disc 26 and the nozzle group to rotate, so that the concentrated hydrochloric acid is dispersed into uniform droplets, increasing the contact area with the raw material. Another set of bevel gear 1 271 drives the stirring rod assembly 25 to rotate through the connecting column, which fully stirs the pulverized raw material and concentrated hydrochloric acid. Under heating conditions, an acidification and hydrolysis reaction occurs inside the mixing chamber 21, destroying the keratin structure and releasing cystine to form a hydrolyzed mixture.

[0046] After the acidification and hydrolysis reaction is completed, the solenoid valve 23 is opened, and the hydrolyzed mixture flows from the mixing chamber 21 into the storage tank 22 for temporary storage; then the pump 41 is turned on, and the pump 41 transports the hydrolyzed mixture in the storage tank 22 through the pipeline to the filter chamber 31, which is about to enter the filtration and separation stage.

[0047] The hydrolyzed mixture enters the multi-stage filter cartridge assembly 34 through the filter cartridge inlet 341 and is filtered by the filter screen 342. At this time, the solution containing cystine flows out from the side of the filter screen 342 and flows into the collection hopper 33. The user can collect the solution from the bottom of the collection hopper 33, and then purify it through neutralization, crystallization and other steps to obtain the L-cystine product. The solid impurities generated by filtration are trapped inside the filter cartridge assembly 34 and supported by the receiving plate 343. After the device is finished, the maintenance cover 32 can be opened to clean the solid impurities in the filter cartridge assembly 34 inside the filter chamber 31 to ensure the stable operation of the device in the future.
