Description

Technical Field

[0001] This application relates to the technical field of chemical production equipment, and in particular to a centrifugal separation and rinsing device for glycine mother liquor. Background Technology

[0002] Glycine is a key fine chemical raw material in the fields of medicine, food, and pesticides. The glycine mother liquor produced during its production process contains glycine residue, ammonium chloride, and volatile components. It is necessary to recover the solid crystals by centrifugation and rinse the equipment to avoid resource waste and environmental pollution, and to ensure continuous production.

[0003] Most commercially available centrifugal separation and rinsing devices for glycine mother liquor use fixed-installation nozzles for rinsing, combined with manual scraping or fixed-position scrapers for unloading. The rinsing range of these devices is limited to the area covered by the nozzles, and blind spots are easily formed in the corners of the inner wall of the drum and the deep pores of the filter screen. Moreover, it is difficult to adjust the fit between the scraper and the inner wall of the drum during unloading, which can easily lead to material residue. At the same time, the removal of the collection tank often requires disassembling the equipment shell, which is a cumbersome operation process. As a result, the connection between the separation, rinsing and unloading processes is time-consuming, making it difficult to achieve efficient and coordinated operation.

[0004] Regarding the aforementioned technologies, the applicant believes that they suffer from low separation efficiency and incomplete rinsing. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a centrifugal separation and rinsing device for glycine mother liquor.

[0006] This application provides a centrifugal separation and rinsing device for glycine mother liquor, which adopts the following technical solution: A centrifugal separation and rinsing device for glycine mother liquor includes a frame on which a centrifugal mechanism is mounted. The centrifugal mechanism includes a housing, a rotating drum, a filter screen, and a first motor. The housing is fixedly mounted on the frame. A feed inlet is located at the top of the housing, and a drain outlet is located at the bottom of the housing. A rotating ring is rotatably mounted on the upper part of the housing. The rotating drum is located inside the housing, with its top rotatably mounted at the bottom of the rotating ring. The base of the first motor is located on the outer side of the bottom of the housing, and the working end of the first motor penetrates through the housing and is fixedly connected to the bottom of the rotating drum. The first motor drives the rotating drum to rotate. Multiple sets of separation holes are formed on the rotating drum, and the filter screen is fixedly mounted on the inner wall of the rotating drum. A rinsing mechanism is provided inside the rotating drum.

[0007] By adopting the above technical solution, a centrifugal mechanism is installed on the frame. This mechanism includes a shell, a rotating drum, a filter screen, and a first motor. The first motor drives the rotating drum to rotate at high speed, generating strong centrifugal force. Combined with multiple sets of separation holes on the drum and the inner wall filter screen, solid-liquid separation of solid crystals and liquid in the glycine mother liquor is achieved. Compared to traditional methods such as vacuum filtration, this centrifugal mode significantly shortens the separation time. Furthermore, the rotating design of the drum top and rotating ring reduces frictional resistance during high-speed drum rotation, lowers additional energy consumption of the motor, and further increases the throughput per unit time. The filter screen can precisely trap solid particles in the mother liquor, preventing fine impurities from mixing into the separated solid products. The rinsing mechanism can specifically rinse the solid material adhering to the inner wall of the drum and the filter screen, removing residual mother liquor and impurities from the solid surface, improving the purity of glycine crystals or recovered ammonium chloride, and reducing the adhesion residue of solid material on the filter screen, thus increasing the material recovery rate. This is of great significance for improving product grade and reducing raw material waste in glycine production.

[0008] Preferably, the rinsing mechanism includes a water spray assembly, a liquid supply pipe, and a liquid supply pump; one end of the liquid supply pipe passes through the housing and is disposed inside the drum, the liquid supply pipe is fixedly disposed on the housing, the other end of the liquid supply pipe is connected to the liquid supply pump, and the base of the liquid supply pump is fixedly disposed on the frame; the water spray assembly is slidably disposed on the liquid supply pipe inside the drum, and the water spray assembly is connected to the liquid supply pipe.

[0009] By adopting the above technical solution, the water spray assembly is slidably installed on the liquid supply pipeline, and the water spray position can be flexibly adjusted to target different areas of the inner wall of the drum. This avoids the problem of blind spots in rinsing that exists in traditional fixed nozzles, allowing the water flow to fully cover the filter screen and the inner wall of the drum. With the liquid supply pump providing stable pressure, the water flow can powerfully flush the attached solid materials, which can not only thoroughly remove the mother liquor impurities remaining on the solid surface and improve the purity of glycine products, but also effectively clean the blockage in the filter screen pores and ensure the liquid throughput during centrifugation.

[0010] Preferably, the water spray assembly includes multiple sets of water spray structures connected in series, with each set of water spray structures slidably connected to another set of water spray structures. Each water spray structure includes a sliding pipe and a drive spring. The lower part of each sliding pipe is provided with multiple sets of flushing nozzles, which are connected to the sliding pipe. The upper part of the sliding pipe is slidably disposed within the liquid supply pipe or within the sliding pipe of another set of water spray structures. The drive spring is sleeved on the sliding pipe, with one end of the drive spring fixedly connected to the sliding pipe and the other end of the drive spring fixedly connected to the liquid supply pipe or the sliding pipe of another set of water spray structures.

[0011] By adopting the above technical solution, multiple sets of water spray structures are connected in series and can slide relative to each other, allowing the rinsing range to flexibly extend with the liquid supply pressure. The water flow pressure pushes each set of sliding pipes to extend sequentially, allowing the flushing nozzles to extend from the top to the bottom of the drum, covering the entire length of the drum. Addressing the layered crystals that easily form on the inner wall of the drum in glycine mother liquor, the multi-layered nozzles can simultaneously flush from different heights and angles, preventing the accumulation of crystal residue. The rinsing force is directly linked to the liquid supply pump pressure. When there is a large amount of residual material inside the drum and the crystals are firmly formed, the liquid supply pump pressure can be increased to push the multiple sets of water spray structures to extend fully, while simultaneously applying high pressure. The water flow creates a strong impact force through the flushing nozzle, effectively breaking down stubborn crystals. When the separated glycine crystals are fine or need to be prevented from breaking, the supply pressure can be reduced. At this time, the extension length of the sliding pipe is shortened, and the water flow impact force is weakened. This can complete a light flush while protecting the integrity of the solid material. The force can be adjusted as needed. The elastic force of the drive spring is balanced with the water flow pressure, so that the extension speed and distance of the sliding pipe are dynamically adapted to the pressure. After the flushing is completed, the supply pump stops supplying pressure, and the rebound force of the drive spring drives each set of sliding pipes to retract in sequence, automatically resetting to the initial position.

[0012] Preferably, the drum is composed of a large conical end and a small conical end; a material collection trough is provided at the bottom of the drum, and the material collection trough is detachably connected to the drum.

[0013] By adopting the above technical solution, the drum adopts a double-cone structure with a combination of a large conical end and a small conical end. When rotating at high speed, the solid particles in the mother liquor are driven by centrifugal force to move directionally from the large conical end to the small conical end along the conical surface, avoiding disorderly accumulation of solid particles in the drum, accelerating the separation speed of solid and liquid, reducing local clogging of the filter screen by solid particles, ensuring liquid throughput efficiency, and increasing the mother liquor processing capacity per unit time. The bottom collection tank is specially used to collect the separated solid materials. At the same time, the collection tank is detachably connected to the drum, and can be directly disassembled when removed. The operation is simple and quick, avoiding secondary contamination of materials caused by complex disassembly, and ensuring the purity of glycine products.

[0014] Preferably, the drum is provided with multiple sets of unloading structures, which are circumferentially arranged at the bottom of the rotating ring. Each unloading structure includes a drive groove, a top spring, a scraper, and a drive plate. The drive groove is located at the bottom of the rotating ring. One end of the drive plate is fixedly mounted on the rinsing mechanism. The top of the scraper is slidably mounted on the drive plate. One end of the top spring is fixedly mounted on one side of the rinsing mechanism, and the other end of the top spring is fixedly mounted on one side of the scraper. A rotating inclined surface is provided on the other side of the drive groove, which slidably abuts against the other side of the scraper, and the scraper conforms to the shape of the inner wall of the drum.

[0015] By adopting the above technical solution, the scraper fits perfectly with the shape of the inner wall of the drum. The rotating ring drives the scraper to move around the drum circumferentially, thoroughly cleaning the solid material adhering to the inner wall of the drum. The rotating inclined surface design of the drive groove creates a progressive pushing effect. When the drive rotating ring rotates, the jacking spring pushes the scraper to slide along the rotating inclined surface, making the scraper approach the inner wall of the drum. This avoids material squeezing and residue caused by instantaneous rigid contact between the scraper and the inner wall. The scraping and peeling are achieved through slow fitting, ensuring that the material adhering to the wall is completely removed without any dead corners.

[0016] Preferably, a material inlet is provided on one side of the housing, and the material inlet is located at the material collection trough; a material inlet gate is provided on the material inlet.

[0017] By adopting the above technical solution, the material receiving opening directly corresponds to the material collection trough position. There is no need to disassemble the shell, drum and other core components, nor is there a need to move the entire equipment. Simply open the material receiving door to directly disassemble and remove the material collection trough from the opening, quickly complete the unloading, material receiving and reset cycle, avoid production interruption caused by cumbersome material receiving, and increase the processing capacity per unit time.

[0018] Preferably, the outer ring of the rotating ring is provided with rotating teeth, and the frame is provided with a driving mechanism for driving the rotating ring to rotate.

[0019] Preferably, the drive mechanism includes a second motor and a main gear. The base of the second motor is fixedly connected to the frame, and the main gear is disposed on the working end of the second motor and meshes with the rotating gear.

[0020] By adopting the above technical solution, gear meshing transmission has the advantages of fixed transmission ratio and rapid response. The second motor drives the main gear to rotate, and by meshing with the rotating teeth of the outer ring of the rotating ring, the rotation angle and speed of the rotating ring can be precisely controlled, thereby realizing the precise adjustment of the adhesion force between the scraper and the inner wall of the drum and the scraping speed, avoiding uneven scraping and material splashing problems.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. Multiple sets of water spray structures are connected in series and can slide relative to each other, allowing the rinsing range to flexibly extend with the liquid supply pressure. The water flow pressure pushes each set of sliding pipes to extend sequentially, allowing the flushing nozzles to extend from the top to the bottom of the drum, covering the entire length of the drum. Addressing the layered crystals that easily form on the inner wall of the drum in glycine mother liquor, the multi-layered nozzles can simultaneously flush from different heights and angles, preventing the accumulation of crystal residue. The rinsing force is directly linked to the liquid supply pump pressure. When there is a large amount of residual material or the crystals are firmly formed inside the drum, the liquid supply pump pressure can be increased to push the multiple sets of water spray structures to extend fully, while simultaneously, high-pressure water flows through... The flushing nozzle generates a strong impact force, effectively breaking down stubborn crystals. When the separated glycine crystals are fine or need to be prevented from breaking, the supply pressure can be reduced. At this time, the extension length of the sliding pipe is shortened, and the water flow impact force is weakened. This can complete a light flush while protecting the integrity of the solid material. The force can be adjusted as needed. The elastic force of the drive spring is balanced with the water flow pressure, so that the extension speed and distance of the sliding pipe are dynamically adapted to the pressure. After the flushing is completed, the supply pump stops supplying pressure, and the rebound force of the drive spring drives each set of sliding pipes to retract in sequence, automatically resetting to the initial position.

[0022] 2. The scraper fits perfectly against the inner wall of the drum. The rotating ring drives the scraper to move circumferentially around the drum, thoroughly cleaning the solid material adhering to the inner wall. The inclined design of the drive groove creates a progressive pushing effect. When the drive ring rotates, the push spring pushes the scraper to slide along the inclined surface, bringing it closer to the inner wall of the drum. This avoids material compression and residue caused by instantaneous rigid contact between the scraper and the inner wall. Slow contact achieves scraping and peeling, ensuring complete removal of adhering material without any dead corners. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0028] This application discloses a centrifugal separation and rinsing device for glycine mother liquor. (Refer to...) Figure 1 and Figure 2 The system includes a frame 1, on which a centrifugal mechanism 2 is mounted. The centrifugal mechanism 2 includes a housing 21, a rotating drum 22, a filter screen 23, and a first motor 24. The housing 21 is fixedly mounted on the frame 1.

The working end of the first motor 24 is fixedly connected to the bottom of the drum 22. The first motor 24 is used to drive the drum 22 to rotate, and the drum 22 rotates rapidly to separate the mother liquor. Multiple sets of separation holes 221 are opened on the drum 22. The filter screen 23 is fixedly installed on the inner wall of the drum 22. The separated liquid part enters the housing 21 through the separation holes 221 and the filter screen 23 and flows to the drain port 212. The separated solid part is left in the drum 22 through the filter screen 23. A rinsing mechanism 3 is provided in the drum 22. The rinsing mechanism 3 is used to rinse the solid part after the mother liquor is separated and flush out the residual impurities.

[0029] Reference Figure 1 and Figure 2The outer ring of the rotating ring 25 is provided with rotating teeth 251. The frame 1 is provided with a drive mechanism 5, which is used to drive the rotating ring 25 to rotate. The drive mechanism 5 includes a second motor 51 and a main gear 52. The base of the second motor 51 is fixedly connected to the frame 1. The main gear 52 is located on the working end of the second motor 51 and meshes with the rotating teeth 251. The drum 22 is composed of a large conical end and a small conical end. The bottom of the drum 22 is provided with a collection trough 222, which is bolted to the drum 22. A material taking opening 213 is provided on one side of the housing 21, which is located at the collection trough 222. A material taking gate 214 is provided on the material taking opening 213. By disassembling the collection trough 222, the collection trough 222 can be taken out from the material taking opening 213 for collection.

[0030] Reference Figure 2 The rinsing mechanism 3 includes a water spray assembly 31, a liquid supply pipe 32, and a liquid supply pump 33. One end of the liquid supply pipe 32 passes through the housing 21 and is disposed inside the drum 22. The liquid supply pipe 32 is fixedly disposed on the housing 21, and the other end of the liquid supply pipe 32 is connected to the liquid supply pump 33. The base of the liquid supply pump 33 is fixedly disposed on the frame 1. The water spray assembly 31 is slidably disposed on the liquid supply pipe 32 inside the drum 22. The water spray assembly 31 is connected to the liquid supply pipe 32. The water spray assembly 31 includes multiple sets of water spray structures 311 connected in series. Each set of water spray structures 311 is slidably connected to the other end of the water spray structure 311. Each water spray structure 311 includes a sliding pipe 3111 and a drive spring 3112. Multiple sets of flushing nozzles 3113 are disposed at the lower part of the sliding pipe 3111. The multiple sets of flushing nozzles 3113 are connected to the sliding pipe 3111. 1. Connecting; the upper part of the sliding pipe 3111 is slidably set inside the liquid supply pipe 32 or inside the sliding pipe 3111 of another set of water spray structures 311; the drive spring 3112 is sleeved on the sliding pipe 3111, one end of the drive spring 3112 is fixedly connected to the sliding pipe 3111, and the other end of the drive spring 3112 is fixedly connected to the liquid supply pipe 32 or the sliding pipe 3111 of another set of water spray structures 311; the flushing liquid enters the liquid supply pipe 32 through the liquid supply pump 33, causing multiple sets of water spray structures 311 to slide outward in sequence under pressure, so that the drum 22 is fully flushed. The elasticity of the drive spring 3112 makes the extension speed and distance of the sliding pipe 3111 dynamically adapt to the pressure. After the flushing is completed, the liquid supply pump 33 stops supplying pressure, and the rebound force of the drive spring 3112 drives each set of sliding pipes 3111 to retract in sequence.

[0031] Reference Figure 2 and Figure 3The drum 22 is equipped with multiple sets of unloading structures 4, which are arranged circumferentially at the bottom of the rotating ring 25. Each unloading structure 4 includes a drive groove 41, a top spring 42, a scraper 43, and a drive plate 44. The drive groove 41 is located at the bottom of the rotating ring 25. One end of the drive plate 44 is fixedly mounted on the liquid supply pipe 32 of the rinsing mechanism 3. The top of the scraper 43 is slidably mounted on the drive plate 44. One end of the top spring 42 is fixedly mounted on one side of the rinsing mechanism 3, and the other end of the top spring 42 is fixedly mounted on one side of the scraper 43. The other end of the drive groove 41... A rotating inclined surface 411 is provided on one side, which slides against the other side of the scraper 43. The scraper 43 fits the shape of the inner wall of the drum 22. When unloading is required, the rotating ring 25 is driven to rotate, and the top spring 42 pushes the scraper 43 to slide along the rotating inclined surface 411 towards the inner wall of the drum 22. The distance between the scraper 43 and the inner wall can be adjusted by the rotation angle of the rotating ring 25. Then, the rotation of the drum 22 cooperates with the scraper 43 to completely clean the solid material. The scraper 43 fits the shape of the inner wall of the drum 22 completely, thoroughly cleaning the solid material attached to the inner wall of the drum 22.

[0032] The working principle of the glycine mother liquor centrifugal separation and rinsing device in this application is as follows: The mother liquor to be treated is injected into the equipment through the feed port 211 at the top of the shell 21 and flows directly into the drum 22 located in the center of the shell 21 to complete the material preparation before separation. The first motor 24 is started, and the working end of the first motor 24 drives the drum 22 to rotate at high speed. During the rotation of the drum 22, a strong centrifugal force is generated. Under the action of centrifugal force, the liquid part in the mother liquor penetrates the filter screen 23 on the inner wall of the drum 22 and overflows into the shell 21 through the multiple sets of separation holes 221 on the drum 22. The liquid flows down along the inner wall of the shell 21 and is finally discharged from the drain port 212 at the bottom of the shell 21, completing the separation and recovery of the liquid. The solid part in the mother liquor cannot penetrate the filter screen 23 due to its large particle size or density difference. It is intercepted by the filter screen 23 and left in the drum 22, realizing the initial separation of solid and liquid.To remove residual impurities from the surface of solid materials and improve the purity of the solid product, the rinsing mechanism 3 is activated, and the liquid supply pump 33 operates, pressurizing the rinsing liquid and delivering it to the liquid supply pipe 32. The liquid supply pipe 32 guides the rinsing liquid into the drum 22. After entering the liquid supply pipe 32, the rinsing liquid generates pressure, pushing multiple sets of water spray structures 311 arranged in series to slide outwards in sequence. Under the action of pressure, the sliding pipe 3111 of each set of water spray structures 311 overcomes the elastic force of the drive spring 3112 and extends from the liquid supply pipe 32 or the previous set of sliding pipes 3111. The elastic characteristics of the drive spring 3112 The extension speed and distance of the sliding pipe 3111 are dynamically adapted to the liquid pressure, ensuring that the multiple sets of water spray structures 311 can cover the entire interior of the drum 22 after deployment. The flushing liquid is evenly sprayed onto the surface of the solid material inside the drum 22 through multiple sets of flushing nozzles 3113 at the bottom of the sliding pipe 3111, thoroughly flushing the solid material and filter screen 23. The waste liquid generated during flushing is also discharged through the separation hole 221 and drain outlet 212 under the action of centrifugal force. After flushing is completed, the liquid supply pump 33 stops supplying pressure, and the rebound force of the drive spring 3112 drives each set of sliding pipes 3111 to return sequentially. The device retracts to its initial position to reserve space for subsequent unloading processes. The second motor 51 is then started. The working end of the second motor 51 drives the main gear 52 to rotate. The main gear 52 meshes with the rotating teeth 251 on the outer ring of the rotating ring 25, thereby driving the rotating ring 25 to rotate on the upper part of the housing 21. When the rotating ring 25 rotates, the rotating inclined surface 411 on the drive groove 41 at the bottom of the rotating ring 25 slides against one side of the scraper 43. Simultaneously, the top force spring 42 continuously applies a pushing force to the scraper 43, pushing the scraper 43 to slide along the drive plate 44 towards the inner wall of the drum 22. The rotation angle of the rotating ring 25 can be adjusted. The scraper 43 is precisely controlled to maintain a close fit with the inner wall of the drum 22, ensuring a perfect fit between the scraper 43 and the inner wall. The first motor 24 operates, and the solid material adhering to the inner wall of the drum 22 is peeled off and falls into the collection trough 222 at the bottom of the drum 22 due to its own rotational inertia and the scraping action of the scraper 43. After unloading, the first motor 24 and the second motor 51 are turned off, and the material collection door 214 at the material collection opening 213 on one side of the housing 21 is opened. The collection trough 222, filled with solid material, is then disassembled and removed from the material collection opening 213, completing the collection of solid material.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
