Description

Technical Field

[0001] This application relates to the field of refining equipment technology, and in particular to a low-temperature refining equipment. Background Technology

[0002] The scouring process for textiles is a process that removes impurities, dirt, and residual sizing agents from natural fibers, or removes non-fibrous substances such as oils and sizing agents from synthetic fibers. During the scouring process, refining agents and surfactants are added to reduce the interfacial tension between the liquid and the fabric, removing impurities while improving the fabric's wetting and penetration properties.

[0003] In related technologies, a refining apparatus has been proposed, including a refining tank, a mounting plate, and a rotating shaft. The mounting plate is horizontally positioned on the refining tank, and the rotating shaft is rotatably connected to the mounting plate and extends into the refining tank. A stirring blade is provided at the bottom of the rotating shaft. When the fabric is immersed in the refining agent in the refining tank for low-temperature refining, the stirring blade on the rotating shaft is driven by a drive motor to rotate, thereby stirring the working liquid and ensuring that the effective components in the working liquid are mixed evenly and thoroughly, thus improving the refining effect.

[0004] Regarding the aforementioned technologies, although the setting of the stirring blade can agitate the working fluid to a certain extent, the stirring blade can only agitate the working fluid at a fixed height. The working fluid at other heights is difficult to contact the fabric, resulting in insufficient reaction of the working fluid and reducing the finishing effect. Utility Model Content

[0005] In order to improve the problem that the stirring blades can only stir the working liquid at a fixed height, resulting in insufficient reaction of the working liquid and reduced refining effect, this application provides a low temperature refining device.

[0006] The low-temperature refining apparatus provided in this application adopts the following technical solution:

[0007] A low-temperature refining apparatus includes a refining drum, a main shaft, a secondary shaft, a rotary drive component, a power drive assembly, and a temperature control mechanism. The refining drum is mounted on a fixed plate. The main shaft is rotatably connected to the fixed plate about a vertical axis and has first helical blades. The rotary drive component drives the main shaft to rotate. The secondary shaft is rotatably connected to the fixed plate about a vertical axis and is evenly distributed around the axis of the main shaft. The secondary shaft has second helical blades. The power drive assembly synchronously drives the secondary shaft to rotate. The main shaft rotates in the opposite direction to the secondary shaft. The temperature control mechanism regulates the temperature of the refining drum.

[0008] By adopting the above technical solution, the rotary drive component drives the main shaft to rotate, which in turn drives the first spiral blade to rotate. This causes the working liquid in the middle of the refining tank to tumble upwards under the influence of the first spiral blade. At the same time, the auxiliary shaft on the side of the main shaft rotates in the opposite direction under the drive of the power drive component, which in turn drives the second spiral blade to rotate in the opposite direction. This causes the working liquid inside and outside the refining tank to tumble downwards. The cooperation between the second spiral blade and the first spiral blade causes the working liquid to continuously tumble up and down, forming a circulation, thereby ensuring that the working liquid is fully mixed and agitated. This improves the problem that the stirring blade can only stir the working liquid at a fixed height, resulting in insufficient reaction of the working liquid and reduced refining effect.

[0009] Optionally, the power drive assembly includes a first gear and a second gear, the first gear being coaxially connected to the main shaft, and the second gear being coaxially connected to each auxiliary shaft, wherein the first gear simultaneously meshes with all the second gears.

[0010] By adopting the above technical solution, when the rotary drive component drives the main shaft to rotate, it drives the first gear to rotate, which in turn drives the second gear to rotate, thereby synchronously driving each auxiliary shaft to rotate in the opposite direction. The structure is simple and easy to use; and no additional power source is required, saving power costs.

[0011] Optionally, a feed roller and a discharge roller are rotatably connected to the top two sides of the refining drum, and a guide roller is rotatably connected to the bottom of the refining drum. The feed roller, discharge roller, and guide roller are parallel and arranged laterally. A support is provided on the refining drum, and a pressure roller is rotatably connected to the support. The pressure roller is parallel to the discharge roller, and a pressure assembly is provided on the support for driving the pressure roller to press against the discharge roller.

[0012] By adopting the above technical solution, during use, the fabric passes over the feed roller and enters the refining tank, passes over the bottom of the guide roller, and then passes over the discharge roller and leaves the refining tank. The fabric in the refining tank is refined by the working fluid. The continuous movement of the fabric allows for continuous refining, improving work efficiency. At the same time, the matching arrangement of the discharge roller and the pressing component allows the fabric to be pressed by the discharge roller and the discharge roller during discharge, thereby squeezing out the working fluid on the fabric, reducing the waste of working fluid, and keeping the fabric clean and tidy.

[0013] Optionally, the pressing assembly includes a slider and a threaded rod. The slider is slidably connected to the support in a vertical direction, and the pressing roller is rotatably connected to the slider about its own axis. The threaded rod is threadedly connected to the support in a vertical direction, and the threaded end of the threaded rod is rotatably connected to the slider about its own axis.

[0014] By adopting the above technical solution, the screw rod can be rotated to move up and down, thereby driving the slider to move vertically up and down, so that the pressure roller can move closer to or further away from the discharge roller. The structure is simple and the adjustment is convenient.

[0015] Optionally, the temperature control mechanism includes an insulation shell, a temperature sensor, and a steam generator. The insulation shell is installed on the outer peripheral wall of the refining drum, and an insulation chamber is formed between the insulation shell and the refining drum. The temperature sensor is located inside the refining drum, and the steam generator is connected to the insulation chamber through a pipe. The steam generator is electrically connected to the temperature sensor.

[0016] By adopting the above technical solution, the working fluid in the refining tank can be uniformly heated by continuously introducing high-temperature steam into the heat preservation chamber through a steam generator. Compared with ignition heating or heating wire heating, steam heating can reduce the risk of local overheating. The matching of temperature sensor and steam generator allows the temperature of the working fluid in the refining tank to be adjusted in a timely manner, and the temperature control is faster and more accurate.

[0017] Optionally, the bottom of the refining tank is connected to a drain pipe, the drain pipe is equipped with a switch valve, and the bottom of the refining tank is equipped with a self-cleaning component.

[0018] By adopting the above technical solution, the drain pipe is designed so that the working fluid can be discharged in a timely manner after refining. The self-cleaning component is designed so that when the working fluid is discharged, impurities and dirt from non-natural fibers left in the fabric during the refining process can also be cleaned and discharged along with the working fluid, reducing the risk of blockage caused by the accumulation of impurities and dirt in the drain pipe during long-term use.

[0019] Optionally, the self-cleaning assembly includes a rotating rod, rotating blades, and a brush. The rotating rod is rotatably connected to the drain pipe, the rotating blades are disposed on the rotating rod, the top of the rotating rod extends into the refining tank, and the brush is disposed on the top of the rotating rod, with the brush in contact with the bottom wall of the refining tank.

[0020] By adopting the above technical solution, when the working fluid is discharged through the drain pipe, the flowing working fluid drives the rotating blades to rotate, thereby driving the brush to scrub the bottom wall of the refining tank. The impurities and dirt brushed up by the brush are discharged along with the working fluid, realizing the cleaning function of the self-cleaning component. The rotating blades are driven by water flow and do not require a power source. The structure is simple and practical.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The coordinated arrangement of the main shaft, auxiliary shaft, rotary drive component, power drive assembly, first spiral blade and second spiral blade enables the working fluid to continuously tumble up and down to form a circulation, thereby ensuring that the working fluid is fully mixed and agitated. This improves the problem that the stirring blade can only stir the working fluid at a fixed height, resulting in insufficient reaction of the working fluid and reduced refining effect.

[0023] 2. The matching arrangement of the pressure roller, discharge roller and pressure assembly ensures that when the continuously moving and refining fabric exits the refining tank, the working fluid on the fabric is squeezed out, reducing the waste of working fluid and keeping the fabric clean and tidy.

[0024] 3. The design of the rotating rod, rotating blades, and brushes allows the working fluid to rotate as it flows through the drain pipe, thereby driving the brushes to scrub the bottom wall of the refining tank. No power source is required, making the structure simple and practical. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses a low-temperature refining apparatus. (Refer to...) Figure 1 The low-temperature scouring device includes a scouring tank 1, a stirring mechanism 2, a material guiding mechanism 3, a temperature control mechanism 4, and a draining mechanism 5. The scouring tank 1 is an open-top cylindrical tank. A fixed plate 11 is welded horizontally to the top of the scouring tank 1. The stirring mechanism 2 is mounted on the fixed plate 11 and is used to thoroughly stir and mix the working liquid inside the scouring tank 1. The material guiding mechanism 3 is located on the scouring tank 1 and is used to guide the fabric into the scouring tank 1. The temperature control mechanism 4 is used to regulate the temperature of the working liquid inside the scouring tank 1. The draining mechanism 5 is located at the bottom of the scouring tank 1 and is used to drain the waste working liquid inside the scouring tank 1.

[0032] The stirring mechanism 2 includes a main rotating shaft 21, a secondary rotating shaft 22, a rotary drive component 23, and a power drive assembly. The main rotating shaft 21 is rotatably connected to the fixed plate 11 about a vertical axis. The main rotating shaft 21 is coaxial with the refining tank 1. A first spiral blade 24 is welded and fixed to the main rotating shaft 21. The first spiral blade 24 is made of corrosion-resistant plastic material, and its diameter can be adjusted according to the size of the refining tank 1, preferably about two-thirds of the inner diameter of the refining tank 1. The rotary drive component 23 is a geared motor. The rotary drive component 23 is bolted and fixed to the top of the fixed plate 11 about a vertical axis, and its rotation shaft is coaxially connected to the main rotating shaft 21. The secondary rotating shaft 22 is rotatably connected to the fixed plate 11 about a vertical axis, and the secondary rotating shafts 22 are evenly distributed around the axis of the main rotating shaft 21. In this application, two sets of secondary rotating shafts 22 are specifically used. A second helical blade 25 is welded and fixed to the auxiliary shaft 22. The diameter of the second helical blade 25 is slightly smaller than that of the first helical blade 24 to avoid collision with the first helical blade 24. The power drive assembly is used to synchronously drive the auxiliary shaft 22 to rotate, and the main shaft 21 rotates in the opposite direction to the auxiliary shaft 22.

[0033] In operation, the rotary drive 23 drives the main shaft 21 to rotate, which in turn drives the first spiral blade 24 to rotate. This causes the working fluid in the middle of the refining tank 1 to tumble upwards under the influence of the first spiral blade 24. At the same time, the auxiliary shaft 22 on the side of the main shaft 21 rotates in the opposite direction under the drive of the power drive assembly, causing the second spiral blade 25 to rotate in the opposite direction. This causes the working fluid inside and outside the refining tank 1 to tumble downwards. The cooperation between the second spiral blade 25 and the first spiral blade 24 continuously tumbles the working fluid, forming a circulation, thus achieving a more uniform mixing effect. This improves upon the problem that the stirring blades can only stir the working fluid at a fixed height, resulting in insufficient reaction of the working fluid and reduced refining effect.

[0034] For example, the power drive assembly includes a first gear 26 and a second gear 27. The first gear 26 is coaxially connected to the main shaft 21, and the second gears 27 are coaxially connected to each auxiliary shaft 22. The first gear 26 meshes with all of the second gears 27 simultaneously. The gear ratio of the first gear 26 and the second gear 27 can be adjusted according to actual working conditions to match different stirring speeds and load requirements. The gear surfaces can be nickel-plated or coated with a wear-resistant coating to extend their service life. When the rotary drive component 23 drives the main shaft 21 to rotate, it drives the first gear 26 to rotate, which in turn drives the second gears 27 to rotate, thereby synchronously driving each auxiliary shaft 22 to rotate in the opposite direction. This eliminates the need for an additional power source, saving on power costs.

[0035] The material guiding mechanism 3 includes a feed roller 31, a guide roller 32, and a discharge roller 33. The feed roller 31 and the discharge roller 33 are rotatably connected to the top sides of the refining tank 1, respectively, and the guide roller 32 is rotatably connected to the bottom of the refining tank 1. The feed roller 31, the discharge roller 33, and the guide roller 32 are parallel and arranged laterally. The fabric passes over the feed roller 31 and enters the refining tank 1, passes over the bottom of the guide roller 32, and then passes over the discharge roller 33 and exits the refining tank 1. The fabric inside the refining tank 1 is refined by the working fluid. The continuously moving fabric allows for continuous refining, improving work efficiency.

[0036] In addition, refer to Figure 2 A support 12 is provided on the refining tank 1, and a pressure roller 34 is rotatably connected to the support 12. The pressure roller 34 is parallel to the discharge roller 33. The support 12 is provided with a pressure assembly for driving the pressure roller 34 to press against the discharge roller 33. The matching arrangement of the discharge roller 33 and the pressure assembly allows the fabric to be pressed by the discharge roller 33 during discharge, thereby squeezing out the working fluid on the fabric, reducing the waste of working fluid, and keeping the fabric clean and tidy.

[0037] Specifically, the pressing assembly includes a slider 35 and a threaded rod 36. The slider 35 is vertically slidably connected to the support 12, and the pressing roller 34 is rotatably connected to the slider 35 around its own axis. The threaded rod 36 is vertically threadedly connected to the support 12, and the threaded end of the threaded rod 36 is rotatably connected to the slider 35 around its own axis. By rotating the threaded rod 36, the slider 35 can be moved vertically up and down, thereby allowing the pressing roller 34 to move closer to or further away from the discharge roller 33. This fulfills the functional requirement of the pressing assembly driving the pressing roller 34 to press against the discharge roller 33.

[0038] Reference Figure 1The temperature control mechanism 4 includes an insulation shell 41, a temperature sensor 42, and a steam generator 43. The insulation shell 41 covers the outer peripheral wall of the refining tank 1, forming an insulation chamber between the insulation shell 41 and the refining tank 1. The insulation shell 41 can be made of high-temperature resistant materials, such as ceramic fiber or asbestos, to reduce heat loss. The temperature sensor 42 is located inside the refining tank 1 and is used to monitor temperature changes in real time. The steam generator 43 is connected to the insulation chamber via a pipe and is electrically connected to the temperature sensor 42. The steam generator 43 automatically adjusts the steam flow rate based on the signal from the temperature sensor 42 to achieve precise temperature control. The steam generator 43 can also be equipped with a preheating module to speed up start-up and improve working efficiency.

[0039] Reference Figure 1 and Figure 3 The draining mechanism 5 includes a drain pipe 51, which is vertically connected to the bottom of the refining tank 1. A switch valve 52 is provided on the drain pipe 51. Furthermore, a self-cleaning assembly is provided at the bottom of the refining tank 1. The self-cleaning assembly includes a rotating rod 53, a rotating blade 54, and a brush 55. The rotating rod 53 is vertically rotatable and connected inside the drain pipe 51. The rotating blade 54 is located at the bottom of the rotating rod 53, the top of the rotating rod 53 extends into the refining tank 1, and the brush 55 is located at the top of the rotating rod 53 and contacts the bottom wall of the refining tank 1. The drain pipe 51 allows the working fluid to be discharged promptly after refining. When the working fluid is discharged through the drain pipe 51, the flowing working fluid drives the rotating blade 54 to rotate, thereby driving the brush 55 to scrub the bottom wall of the refining tank 1. The impurities and dirt brushed up by the brush 55 are discharged along with the working fluid, realizing the cleaning function of the self-cleaning component. The rotating blade 54 is driven by water flow and does not require a power source, making the structure simple and practical.

[0040] The implementation principle of the low-temperature scouring device in this application embodiment is as follows: When in use, the fabric passes over the feed roller 31 and enters the scouring tank 1, passes over the bottom of the guide roller 32 and then passes over the top of the discharge roller 33 and leaves the scouring tank 1. The fabric in the scouring tank 1 is scourted by the working fluid. The continuously moving fabric enables the fabric to be continuously scourted, thereby improving work efficiency.

[0041] During the refining process, the rotary drive 23 drives the main shaft 21 to rotate, which in turn drives the first spiral blade 24 to rotate. This causes the working liquid in the middle of the refining tank 1 to tumble upwards under the drive of the first spiral blade 24. At the same time, under the transmission of the first gear 26 and the second gear 27, the auxiliary shafts 22 are driven to rotate in opposite directions, causing the working liquid inside and outside the refining tank 1 to tumble downwards. The second spiral blade 25 and the first spiral blade 24 work together to make the working liquid continuously tumble up and down to form a circulation, thereby achieving a more uniform mixing effect. This improves the problem that the stirring blades can only stir the working liquid at a fixed height, resulting in insufficient reaction of the working liquid and reduced refining effect.

[0042] By rotating the threaded rod 36, the threaded rod 36 moves downward, which in turn moves the slider 35 downward, so that the pressure roller 34 presses the fabric against the discharge roller 33. When the fabric is removed from the discharge roller 33, the working fluid on the fabric is squeezed out, reducing the waste of working fluid and keeping the fabric clean and tidy.

[0043] The above are all optional 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.
