Description

Technical Field

[0001] This application relates to the field of textile oil agent use, and particularly to a textile oil agent mixing and stirring device. Background Art

[0002] Textile oil agent mixing and stirring devices play an important role in the textile industry. They can effectively mix oil agents and water evenly, thereby improving the quality of textiles. With the development of the textile industry, the application of mixing and stirring devices is becoming more and more widespread. It is not only widely used in the textile field, but also in other industrial productions that require the mixing of oil agents and water, greatly improving production efficiency and product quality.

[0003] In the existing textile oil agent mixing and stirring technologies, common stirring devices are mainly divided into two categories: one is that the motor is installed above the tank body, and the stirring shaft is driven to rotate through a transmission shaft; the other is that the motor is installed below the tank body, and the shaft is connected to the stirring shaft inside the tank body. The former has a relatively simple structure, but the overall height of the equipment is relatively large, and it is inconvenient for maintenance or cleaning of the tank body. The latter can reduce the height of the equipment, but since the motor shaft passes through the tank body wall, a sealing device needs to be installed between the tank body wall and the motor shaft, which increases the complexity and maintenance cost of the equipment.

[0004] In the prior art, when the motor is installed below the tank body, a sealing device needs to be installed between the motor shaft and the tank body wall. During the long-term operation of the stirring tank body, the sealing device between the motor shaft and the tank body wall will be mechanically worn, resulting in a decline in sealing performance. When the motor operates, heat will be generated, and the heat will be transmitted to the sealing device. This temperature change will cause the material properties of the sealing device to change, reducing its sealing effect. Especially in working conditions with frequent temperature changes, the sealing parts are more likely to be damaged. Once the sealing device is damaged, textile oil agents will leak, so the sealing device needs to be replaced regularly, increasing the maintenance cost. Summary of the Invention

Specific embodiments

[0028] The following further describes the present application in detail with reference to all the drawings.

[0029] An embodiment of the present application discloses a textile oil agent mixing and stirring device.

[0030] Referring to Figure 1 , a textile oil agent mixing and stirring device includes a stirring tank 1, a feed inlet 11 is provided at the upper end of the stirring tank 1, a discharge pipe 12 is provided at the lower end of the stirring tank 1, and a motor 2 is provided on the outer side wall of the lower end of the stirring tank 1.

[0031] Referring to Figure 1 , specifically, the stirring tank 1 includes a tank cover 14 and a tank body 15. The tank cover 14 and the tank body 15 are connected by flange bolts, and the tank cover 14 is located above the tank body 15. The feed inlet 11 is located at the upper end of the tank cover 14, the discharge pipe 12 is located at the lower end of the tank body 15, and a valve 121 is provided on the discharge pipe 12. The material of the tank body 15 can be selected according to the use requirements, such as stainless steel or special alloy. Lifting lugs can be provided above the tank cover 14 to facilitate the use of lifting equipment to lift the tank cover 14 during maintenance.

[0032] Referring to Figure 2 and Figure 3, a lower end of the mixing tank 1 is recessed inwardly into the mixing tank 1 to form an isolation sleeve 3. The isolation sleeve 3 is made of a special corrosion-resistant material such as stainless steel or polytetrafluoroethylene. The upper end of the isolation sleeve 3 is closed, and the lower end of the isolation sleeve 3 is fixedly connected to the lower end of the mixing tank 1. The lower end opening of the isolation sleeve 3 communicates with the outside of the mixing tank 1. The isolation sleeve 3 and the mixing tank 1 are connected by welding or integrally formed during casting to enhance the sealing performance between the isolation sleeve 3 and the mixing tank 1. An outer magnetic ring 31 is provided inside the isolation sleeve 3, and the outer magnetic ring 31 is connected to the shaft of the motor 2. An inner magnetic ring 32 is provided on the outer side wall of the isolation sleeve 3. The inner magnetic ring 32 is located inside the mixing tank 1. A protective sleeve 41 is sleeved outside the inner magnetic ring 32. A mixing shaft 4 is provided at one end of the protective sleeve 41 away from the isolation sleeve 3. The material of the protective sleeve 41 is the same as that of the isolation sleeve 3, forming a sealed protective layer to prevent the medium inside the mixing tank 1 from contacting the inner magnetic ring 32 and the outer magnetic ring 31. The isolation sleeve 3 is a sleeve made of a non-magnetic material, located between the inner magnetic ring 32 and the outer magnetic ring 31, which not only isolates the inner magnetic ring 32 and the outer magnetic ring 31, but also provides an additional sealing layer.

[0033] Referring to Figure 3 , through the above structure, the motor 2 can drive the outer magnetic ring 31 to rotate, and then drive the inner magnetic ring 32 and the mixing shaft 4 to rotate, so that the materials added to the inside of the mixing tank 1 are fully mixed. The diameter and thickness of the magnetic ring can be selected according to actual needs to ensure the magnetic force transmission effect. The material of the magnetic ring is usually a strong magnetic material such as neodymium iron boron.

[0034] The above structure does not require any mechanical shaft seal, avoiding problems such as shaft seal wear and leakage, and is especially suitable for mixing operations that require a sterile or pollution-free environment. At the same time, it reduces maintenance work and extends the service life of the equipment. Since there is no physical connection between the mixing shaft 4 and the motor 2, even if the pressure or temperature inside the container is abnormal, it will not affect the driver, improving the safety of operation. It is applicable to liquids of various viscosities, from low-viscosity aqueous solutions to high-viscosity slurries, and can effectively mix them. By adjusting the speed of the external motor 2, the speed of the mixing shaft 4 can be precisely controlled to achieve precise control of the mixing process.

[0035] Referring to Figure 2 , mixing blades 42 and a plurality of mixing rods 43 are provided on the mixing shaft 4. The mixing blades 42 are located below the mixing rods 43. The mixing blades 42 include blades, and the blades are made of a corrosion-resistant material such as stainless steel or polytetrafluoroethylene. The blades can be fixed to the mixing shaft 4 by key or threaded connection to ensure that the blades will not loosen or fall off during the mixing process. For example, axial positioning can be achieved by a key and fixed by fasteners such as bolts, so that the blades and the mixing shaft 4 form a reliable connection.

[0036] Referring to Figure 2, the stirring rod 43 can break up the materials poured into the stirring tank 1, so that they are evenly mixed and stirred. The stirring rod 43 is arranged circumferentially along the stirring shaft 4 and axially along the axis of the stirring shaft 4, improving the uniformity and efficiency of stirring, ensuring that the materials are fully mixed, and forming a stable textile finishing agent.

[0037] Referring to Figure 2 and Figure 4 , specifically, the stirring rod 43 includes a main rod 431, a sub-rod 432 and an elastic member 433. One end of the main rod 431 away from the sub-rod 432 is fixedly connected to the stirring shaft 4, and the elastic member 433 is fixedly connected between the main rod 431 and the sub-rod 432. The material of the main rod 431 can be selected from stainless steel or aluminum, and the material of the sub-rod 432 can be selected from copper or copper alloy. The elastic member 433 can be made of materials such as springs or rubber. The connection between the main rod 431 and the sub-rod 432 through the elastic member 433 enables the sub-rod 432 to have a certain swing amplitude during the stirring process, reducing local stress and improving the stirring effect. The main rod 431 is made of high-strength steel or titanium alloy, and the sub-rod 432 is made of glass fiber or carbon fiber. Elastic components such as springs or rubber parts are used to absorb the vibration and impact generated during the stirring process. For example, high-strength steel is suitable for general load occasions, and titanium alloy is suitable for high-load environments. Glass fiber materials have good corrosion resistance, while carbon fiber is more suitable for high-speed stirring environments. The elastic component can be made of rubber or spring. Rubber is suitable for general wear-resistant occasions, and spring is suitable for high-impact working conditions.

[0038] In other embodiments, the main rod 431 and the sub-rod 432 can also be fixed by welding or bolts. The shape of the sub-rod 432 can be designed as a straight rod, a bent rod or a spiral rod. Each main rod 431 and sub-rod 432 can rotate independently, increasing the stirring effect.

[0039] Referring to Figure 2 , the inner wall of the stirring tank 1 is provided with a diversion groove 13 for guiding the textile finishing agent to form a more orderly vortex flow and reducing the erosion wear of the inner wall of the cavity.

[0040] Referring to Figure 2, Specifically, the flow guide groove 13 is arranged in a spiral structure and is located on the inner wall of the stirring tank 1. The width of the flow guide groove 13 is from [width value] to [width value], and the depth is from [depth value] to [depth value]. The material of the flow guide groove 13 is the same as that of the tank body 15, such as stainless steel or special alloy. The flow guide groove 13 can guide the textile finishing agent and water to flow along the spiral direction, forming a vortex flow, improving the mixing effect while preventing the material from directly impacting the inner wall and reducing wear. The stirring effect can also be improved by optimizing the number and shape of the flow guide grooves 13. For example, the number and angle of the spiral flow guide grooves 13 can be customized according to the characteristics of the specific stirred material. In addition, the flow guide groove 13 can further improve its wear resistance by adding an anti-wear coating (such as a silicon nitride coating or a tungsten carbide coating). For example, the silicon nitride coating has good high-temperature wear resistance; the tungsten carbide coating is suitable for high-intensity wear conditions. In addition, the stirring effect can be optimized by using a combination of flow guide grooves 13 with different shapes. For example, straight grooves are used for the initial mixing of materials, and spiral grooves are suitable for improving the overall mixing uniformity.

[0041] Refer to Figure 2 , A lifting ring 44 is provided at the upper end of the stirring shaft 4, which is convenient for lifting the stirring shaft 4 during maintenance and cleaning.

[0042] Refer to Figure 2 , Specifically, the lifting ring 44 is installed at the upper end of the stirring shaft 4, and the material is selected from stainless steel or aluminum alloy. The lifting ring 44 can be designed as a ring shape or a hook shape. The lifting ring 44 is fixedly connected to the stirring shaft 4 to ensure the firmness and reliability of the lifting ring 44. After removing the tank cover 14, use a lifting device to hook the lifting ring 44 and take out the stirring shaft 4 from the tank body 15, which simplifies the installation and maintenance process of the stirring device and improves the operation convenience of the equipment.

[0043] Refer to Figure 2 , The inner wall of the stirring tank 1 is provided with a self-cleaning coating for reducing material adhesion. The self-cleaning coating on the inner wall of the stirring tank 1 can significantly reduce the adhesion of the textile finishing agent mixture on the inner wall of the tank body 15, facilitating cleaning and maintenance, while reducing the contamination of the residue to the subsequent batch of mixtures and improving the product quality.

[0044] Refer to Figure 2, Specifically, the self-cleaning coating is sprayed on the inner wall of the tank body 15 with special paint. For example, epoxy resin or polytetrafluoroethylene paint can be selected. The coating thickness can be chosen according to actual usage requirements. The self-cleaning coating has good anti-sticking and corrosion resistance properties, reducing the adhesion of textile oil agents and water during the stirring process and facilitating subsequent cleaning. The self-cleaning coating can adopt a double-layer structure design, with the outer layer being a Teflon coating and the inner layer being a nano-aluminum oxide coating. The Teflon coating has good hydrophobicity and anti-adhesion properties, and the nano-aluminum oxide coating increases the surface hardness and improves the anti-wear property. For example, the Teflon coating selects PFA or FEP materials, and the nano-aluminum oxide coating can select a nano-aluminum powder coating. In addition, the performance can be further optimized by using coating materials with different self-cleaning mechanisms. For example, the nano-silver ion coating is suitable for environments with high hygiene requirements, and the nano-titanium dioxide coating has both antibacterial and self-cleaning dual functions.

[0045] The implementation principle of a textile oil agent mixing and stirring device in an embodiment of this application is as follows: An isolation sleeve 3 is designed at the lower end of the stirring tank 1. An outer magnetic ring 31 is installed inside the isolation sleeve 3 and is connected to the shaft of the motor 2. An inner magnetic ring 32 is installed on the outer side wall. The rotation of the stirring shaft 4 is achieved through the magnetic coupling of the inner magnetic ring 32 and the outer magnetic ring 31. The isolation sleeve 3 and the stirring tank 1 are connected by welding or integrally formed. There is no gap between the isolation sleeve 3 and the stirring rod 43. The inner magnetic ring 32 and the outer magnetic ring 31 are respectively located inside and outside the tank body 15. There is no need to open a through hole at the lower end of the stirring tank 1 for connecting the stirring shaft 4 to the motor 2, eliminating the traditional sealing device, preventing the risk of leakage, and reducing the maintenance cost. The design of the protective sleeve 41 protects the inner magnetic ring 32 from being eroded by the materials inside the stirring tank 1 and extends the service life of the device.

[0046] The above are all the preferred embodiments of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
