Description

Technical Field

[0001] This utility model relates to the field of anhydrous lanolin removal technology, specifically to a device for removing nonionic detergents from anhydrous lanolin. Background Technology

[0002] During production and application, anhydrous lanolin may be affected by nonionic detergent residues, leading to performance degradation or impacting subsequent uses. Therefore, the rational and effective removal of these residues is crucial for ensuring the quality of anhydrous lanolin. To effectively remove nonionic detergent residues from anhydrous lanolin, accurate residue detection is essential. Common methods include surface tension measurement, UV-Vis spectroscopy, HPLC, and infrared spectroscopy. Various strategies can be employed to remove residues. Physical washing methods include multiple rinsings with pure water, using ultrasound to facilitate detergent removal, and, when necessary, using organic solvents such as ethanol or isopropanol for auxiliary cleaning. Chemical treatment measures include using detergent degrading agents or adjusting the pH of the washing solution to enhance cleaning effectiveness. Furthermore, combined physical and chemical processes, such as ultrafiltration, can effectively remove fine residues. For subsequent processing, heating and vacuum drying can promote the volatilization and decomposition of residues.

[0003] The apparatus for removing nonionic detergents from anhydrous lanolin, as disclosed in authorization announcement number CN210481331U, includes an extraction tank, a distillation tank, and a recovery tank. The extraction tank has a top cover, and from left to right on the top of the top cover are arranged a first electric telescopic rod, a feed inlet, a stirring motor, a second electric telescopic rod, and a third electric telescopic rod. The tops of the first and third electric telescopic rods are equipped with cleaning devices. The bottom of the stirring motor is equipped with a stirring device. The top of the second electric telescopic rod is equipped with a liquid extraction device. The side wall of the extraction tank has a heat-insulating heating chamber, and the side wall of the distillation tank has a distillation heating chamber. The recovery tank has an extractant inlet located in the center of its top. By shortening the first and third electric telescopic rods downwards, the top plate and connecting rod descend, causing the rubber ring fixed to the outer ring of the fixing ring to descend tightly against the inner wall of the extraction tank. During the descent, the mixture of extractant and anhydrous lanolin adhering to the inner wall of the extraction tank is scraped off and flows downwards to collect before entering the distillation tank. However, the nonionic detergent in the above-mentioned technical solution has good emulsifying ability and can encapsulate grease to form an emulsion. This emulsification state makes the detergent and grease form a stable emulsion, which hinders the complete removal of detergent. At this time, due to insufficient rinsing and stirring, the residual nonionic detergent will continue to exist in the lanolin, affecting its purity and subsequent performance. Utility Model Content

[0004] The purpose of this invention is to provide a device for removing nonionic detergents from anhydrous lanolin, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nonionic detergent removal device for anhydrous lanolin, comprising a frame, a cleaning tank installed inside the frame, and a rotary drum rotatably installed inside the cleaning tank. At least one top plate is attached to the top of the rotary drum via a snap-fit. A nozzle assembly is installed at a non-central axis position inside the rotary drum. A gear transmission structure for maintaining power transmission is installed between the nozzle assembly and the rotary drum. A reduction motor for driving the nozzle assembly to rotate is installed on one outer wall of the frame. One end of the nozzle assembly extends through to the outside of the rotary drum and is fitted with a rotary joint. A motor controller electrically connected to the input end of the reduction motor is installed on one outer wall of the frame.

[0006] Preferably, both ends of the rotary drum are provided with openings, and a number of ribs are integrally formed in a ring at equal intervals on the inner wall of the rotary drum.

[0007] Preferably, the rotary drum is made of stainless steel, and two symmetrical support wheels are installed on the left and right inner walls of the cleaning tank. The support wheels are used to assist the rotary drum in rotating.

[0008] Preferably, right-angle drain pipes with on / off valves are installed on both sides of the bottom of the cleaning tank.

[0009] Preferably, the nozzle assembly includes two bearing seats fixed to the top wall of the frame, a hollow tube rotatably mounted between the two bearing seats, and a plurality of nozzles evenly spaced on the outer circumference of the hollow tube.

[0010] Preferably, the gear transmission structure includes a drive gear fixed to one end of the surface of the hollow tube and an internal gear ring fixed to one port of the rotary drum, wherein the drive gear and the internal gear ring mesh with each other.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This nonionic detergent removal device for anhydrous lanolin uses a structure that includes a washing tank, a rotating drum, a spray nozzle assembly, a motor controller, a geared motor, and a gear transmission structure. The wool material to be cleaned, along with any lanolin and nonionic detergent residue, is placed in the rotating drum. The geared motor drives the spray nozzle assembly and the rotating drum to rotate via the gear transmission structure. The rotation of the rotating drum causes the wool material to continuously tumble, while the spray nozzle assembly continuously sprays and washes the tumbling wool material, using the sprayed organic solvent to rinse away the anhydrous lanolin and nonionic detergent, thus removing the nonionic detergent. The discharged liquid is then subjected to distillation and purification. The rotation of the rotating drum enables the material to... The complete tumbling ensures that the wool material is continuously exposed to the sprayed organic solvent during the cleaning process. The continuous tumbling ensures that every part of the material is evenly contacted with the cleaning solution, thereby improving the overall cleaning efficiency. Compared with static or simple stirring, the rotation of the rotary drum can better avoid dead corners and local residues, ensuring that lanolin and non-ionic detergents are fully rinsed and reducing the accumulation of residues. Secondly, the design of the spray nozzle assembly brings a continuous and uniform spraying effect. Rotary spraying can effectively wash away residues on the surface and in the microstructure of the material, especially emulsifier residues that are difficult to remove by traditional rinsing methods. During the spraying process, the flow of solvent continuously carries away the impurities and residues that are washed away, forming a dynamic cleaning environment that greatly improves the thoroughness of the cleaning.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] Please see Figure 1-6 An embodiment of this utility model provides a nonionic detergent removal device for anhydrous lanolin, comprising a frame 1, a cleaning tank 2 installed inside the frame 1, and a rotary drum 3 rotatably installed inside the cleaning tank 2. At least one top plate 4 is installed at the top of the rotary drum 3 by a snap fastener. A nozzle assembly 6 is installed at a non-central axis position inside the rotary drum 3. A gear transmission structure 10 for maintaining power transmission is installed between the nozzle assembly 6 and the rotary drum 3. A reduction motor 8 for driving the rotation of the nozzle assembly 6 is installed on one side of the outer wall of the frame 1. One end of the nozzle assembly 6 extends through to the outside of the rotary drum 3 and is equipped with a rotary joint 7. A motor controller 9 electrically connected to the input end of the reduction motor 8 is installed on one side of the outer wall of the frame 1.

[0021] Both ends of the rotary drum 3 are provided with openings. Several ribs 301 are integrally formed in a ring at equal intervals on the inner wall of the rotary drum 3. The rotary drum 3 drives the wool material to turn over fully in the cleaning liquid, ensuring that each part can be evenly contacted by the sprayed cleaning liquid. The ribs 301 are used to create a beating effect on the wool material.

[0022] The rotary drum 3 is made of stainless steel. Two symmetrical support wheels 202 are installed on the left and right inner walls of the cleaning tank 2. The support wheels 202 are used to assist the rotary drum 3 in rotating. The cleaning tank 2 is used to provide a closed and stable space for holding the cleaning liquid, so that the rotary drum 3 continuously forces the wool material to impact the cleaning liquid during the tumbling process.

[0023] Both sides of the bottom of the cleaning tank 2 are equipped with right-angle drain pipes 201 with switch valves;

[0024] The nozzle assembly 6 includes two bearing seats 5 fixed on the top wall of the frame 1, a hollow tube 601 rotatably mounted between the two bearing seats 5, and a number of nozzles 602 evenly spaced on the outer circumference of the hollow tube 601. The drive shaft of the geared motor 8 drives the hollow tube 601 to rotate, causing the hollow tube 601 to rotate on its own axis. At this time, the nozzles 602 rotate around the hollow tube 601 and continuously spray organic solvent to ensure that every part of the wool material can be fully rinsed.

[0025] The gear transmission structure 10 includes a drive gear 1001 fixed to one end of the surface of the hollow tube 601 and an internal gear ring 1002 fixed to one port of the rotary drum 3. The drive gear 1001 and the internal gear ring 1002 mesh with each other. The hollow tube 601 drives the internal gear ring 1002 and the rotary drum 3 to rotate through the drive gear 1001. During this process, the support wheel 202 is used to support the rotation of the rotary drum 3. The gear transmission structure 10 has the advantages of compact structure, high transmission efficiency, large torque transmission and high reliability, and realizes precise control of the rotary drum.

[0026] In this embodiment, the operator first opens the top plate 4 and places the wool material to be cleaned into the rotary drum 3. During this process, the drum should be loaded appropriately according to its quantity and properties to avoid overfilling or underfilling, ensuring optimal rotation and material agitation. After loading, the top plate 4 at the inlet of the rotary drum 3 is closed to prevent material from falling during cleaning. Then, the device is started, and the motor controller 9 adjusts the speed of the reduction motor 8, causing the reduction motor 8 to drive the gear transmission structure 10 to slowly rotate the rotary drum 3. The rotation of the rotary drum 3 continuously agitates the wool material, preventing over-cleaning or residue buildup. The operator can set a suitable speed according to the material's characteristics to ensure sufficient agitation while avoiding excessive speed that could cause mechanical vibration or damage to the device. After the rotary drum 3 begins to rotate, the operator turns on the delivery pump connected to the spray nozzle assembly 6 to start the washing program. During rotation, the nozzle assembly 6 continuously sprays organic solvent to wash away non-ionic detergent residues on the wool material. The spraying time should be adjusted according to the concentration of residues and the cleaning effect. It is generally recommended to spray continuously for a certain period of time to ensure that the residues are fully washed away. During the spraying process, the rotation of the rotary drum 3 continuously turns the material to ensure that each part can fully contact the sprayed solvent and achieve uniform cleaning. After cleaning, the operator should stop the reduction motor 8, turn off the conveying pump connected to the nozzle assembly 6, slow down the rotation speed of the rotary drum 3, and gradually stop it from rotating. Open the top plate 4 at the top of the rotary drum 3 to remove the cleaned wool material. After removal, the wool should be rinsed or dried to ensure that the residual solvents and impurities are completely removed. The rinsing liquid discharged from the right-angle drain pipe 201 can be recycled after distillation and purification, and anhydrous lanolin can be further extracted from the rinsing liquid.
