Description

Technical Field

[0001] This utility model relates to the field of textile printing and dyeing equipment technology, and in particular to a low-liquor-ratio dyeing machine that saves energy and water. Background Technology

[0002] Traditional dyeing machines require a large amount of water during the dyeing process, and the heating of the dye liquor and the treatment of wastewater both consume energy. Therefore, if the liquor ratio can be further reduced in this process, the consumption of various energy sources can be reduced.

[0003] Currently, Chinese utility model patent CN209584564U3 discloses an energy-saving dual-tube dyeing machine, belonging to the technical field of fabric liquid phase treatment devices. It includes one cylinder and at least two guide tubes; the cylinder has at least two fabric storage tanks inside; adjacent fabric storage tanks are separated by a partition; guide tubes are arranged below the cylinder; the number of guide tubes is the same as the number of fabric storage tanks; one end of each guide tube is installed at the front end of the cylinder and communicates with the corresponding fabric storage tank, and the other end is installed at the rear end of the cylinder and communicates with the corresponding fabric storage tank; each guide tube and its corresponding fabric storage tank form a separate circulation path for the fabric. This dyeing machine saves floor space while significantly increasing the fabric storage space and capacity within a single cylinder; moreover, because the fabric is distributed in two independent storage spaces, the squeezing force when the fabric moves within a single storage tank is dispersed, preventing excessive squeezing and large-area wrinkling of the fabric, thus achieving a lower liquor ratio and significantly improving the dyeing quality. Although the technical solution proposes to increase the space of the storage tank by adding a partition plate, the storage tank plate is a static partition structure and the through holes on its surface are only used for one-way permeation of dye liquor. This results in a large amount of dye liquor being retained in the ineffective liquid accumulation chamber and cannot be recycled. At the same time, the liquid level control in the storage tank depends on the overall water injection volume and cannot dynamically adjust the water injection volume of the dye liquor according to the amount of fabric, thus increasing water consumption and production costs. Utility Model Content

[0004] In order to address the technical deficiencies mentioned in the background art, the purpose of this utility model is to provide an energy-saving and water-saving low liquor ratio dyeing machine. By dynamically constraining the flow range of the dye liquor, it ensures that the dye liquor only acts on the effective area of ​​the fabric, thereby effectively solving the problems of low dye liquor utilization and high water consumption in traditional dyeing processes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A low-liquor-ratio dyeing machine that saves energy and water includes a main body. A fabric storage plate is mounted at the bottom of the main body. Guide plates are inclined upward on both sides of the fabric storage plate, and multiple through holes for the dye liquor to pass through are evenly opened on the surface of the fabric storage plate. An adjustable through hole assembly is provided in each through hole. The adjustable through hole assembly includes an electromagnetic drive unit, an elastic sealing ring, and an aperture adjustment ring. The elastic sealing ring is sleeved between the electromagnetic drive unit and the aperture adjustment ring. The electromagnetic drive unit and the aperture adjustment ring are concentric double-layer ring structures. The electromagnetic drive unit is the inner ring and its surface is provided with serrated guide patterns. The aperture adjustment ring is the outer ring and its axial displacement is controlled by the electromagnetic drive unit to achieve continuous adjustment of the through hole aperture within the range of 0-10mm.

[0007] Preferably, a plurality of guide fins are provided on the outer surface of the guide plate, and a wave-shaped turbulence groove is formed between two adjacent guide fins. The extension direction of the turbulence groove is consistent with the length of the main body of the cylinder.

[0008] Preferably, one end of the guide plate is fixedly connected to the storage cloth plate, and the other end is welded to the inner wall of the cylinder body. The angle between the guide plate and the storage cloth plate is 15°-30°.

[0009] Preferably, the cloth storage plate divides the inner cavity of the cylinder body into an upper cloth storage trough and a lower liquid accumulation chamber, and the cloth storage trough and the liquid accumulation chamber are connected by a through hole in the cloth storage plate.

[0010] Preferably, a circulation pump interface is provided at the bottom of the main body of the cylinder, one end of which is connected to the liquid accumulation chamber and the other end is connected to an external circulation pump.

[0011] Preferably, the circulating pump interface is also connected to a circulating channel, which has an arc-shaped structure, and the other end of the circulating channel is connected to the side wall of the cylinder body and communicates with the cloth storage tank.

[0012] Preferably, the inner wall of the circulation channel is covered with a microporous filter membrane with a pore size of 0.1-0.5 mm.

[0013] Preferably, the inner wall of the cylinder body is provided with multiple sets of liquid level sensors, and the multiple sets of liquid level sensors are respectively linked with the adjustable through hole assembly and the circulation pump interface through the controller to form a closed-loop control system.

[0014] In summary, the beneficial effects of this utility model are as follows:

[0015] This invention uses an adjustable through-hole component to dynamically constrain the flow range of the dye liquor, ensuring it only acts on the effective area of ​​the fabric. This effectively solves the problems of low dye liquor utilization and high water consumption in traditional dyeing processes. Furthermore, by setting up a circulation channel to establish a forced convection path between the fabric storage tank and the circulation pump, centrifugal force is used to accelerate the circulation of the dye liquor. The opening of the through-hole is dynamically adjusted according to real-time liquid level data to achieve on-demand distribution of the dye liquor. As a result, the circulation of the dye liquor can be controlled according to the actual production situation, reducing dye liquor retention and improving the utilization efficiency of the dye liquor.

[0026] The following is in conjunction with the appendix Figure 1-5 The present invention provides a more detailed description of an embodiment of an energy-saving and water-saving low-liquor-ratio dyeing machine.

[0027] A low-liquor-ratio dyeing machine that saves energy and water, such as Figure 1 , 2 As shown, the device includes a main body 1, with a storage plate 2 mounted on the bottom of the main body 1. Guide plates 3 are inclined upwards on both sides of the storage plate 2, and multiple through holes 21 are evenly distributed on the surface of the storage plate 2 to allow dye liquor to pass through. An adjustable through hole 21 assembly is installed within each through hole 21. The adjustable through hole 21 assembly includes an electromagnetic drive unit 41, an elastic sealing ring 42, and an aperture adjustment ring 43. The elastic sealing ring 42 is sleeved between the electromagnetic drive unit 41 and the aperture adjustment ring 43. The electromagnetic drive unit 41 and the aperture adjustment ring 43 are concentric double-layer ring structures. The electromagnetic drive unit 41 is the inner ring and has a serrated guide pattern on its surface. The aperture adjustment ring 43 is the outer ring, and its axial displacement is controlled by the electromagnetic drive unit 41 to achieve continuous adjustment of the through hole 21 aperture within the range of 0-10 mm.

[0028] Specifically, the adjustable through-hole 21 assembly uses an electromagnetic coil as its electromagnetic drive unit 41. When energized, the electromagnetic coil generates a magnetic field, driving the magnetic core (connected to the outer ring) to move axially with a displacement accuracy of ±0.1mm. The maximum stroke of the aperture adjustment ring 43 is 10mm, and the gap between the two rings is 0.5mm, resulting in a leakage rate of <0.1L / min at 10bar pressure, superior to traditional single-layer sealing structures (leakage >1L / min). The electromagnetic drive unit 41 controls the displacement of the aperture adjustment ring 43 to change the effective area of ​​the through-hole 21, thereby enabling automatic control of the dye liquor flow based on the water level. The inner ring surface has serrated guide patterns (2mm spacing) to guide the dye liquor flow, reduce flow resistance, increase flow rate by 15%, and prevent fiber impurity accumulation. The outer ring covers the inner ring surface, changing the opening of the through-hole 21 through relative displacement. The opening control range is 0mm (fully closed) to 10mm (fully open), achieving linear flow regulation. The elastic sealing ring 42 is made of fluororubber, which elastically deforms when the outer ring moves, always fitting the gap between the inner and outer rings to prevent dye leakage. Furthermore, the adjustable through-hole 21 assembly has a self-locking design; when power is off, the electromagnetic drive unit 41 resets via a spring, forcibly closing the through-hole 21 to a safe state (0mm diameter). By utilizing electromagnetic-mechanical linkage control and integrating a position feedback sensor, the displacement of the outer ring is corrected in real time, ensuring long-term operational stability. By adjusting the diameter of the through-hole 21 on the fabric storage plate 2 according to instructions, the dye liquor circulation can be controlled according to actual production conditions, reducing dye liquor retention and improving dye liquor utilization efficiency.

[0029] In this embodiment, as Figure 2 As shown, multiple guide fins 31 are provided on the outer surface of the guide plate 3, and a wave-shaped turbulence groove 311 is formed between two adjacent guide fins 31. The extension direction of the turbulence groove 311 is consistent with the length of the cylinder body 1.

[0030] Specifically, the guide plate 3 is located on the left and right sides of the fabric storage plate 2, and the guide plate 3 is obliquely connected to the inner wall of the fabric storage plate 2 and the main body 1 of the cylinder. Several interconnected guide fins 31 are provided on the outer surface of the guide plate 3. A wave-shaped turbulence groove 311 is formed between two adjacent guide fins 31. When the dye liquor flows through the turbulence groove 311, the structure causes the dye liquor to flow faster and pushes the dye liquor to form turbulence along the wave-shaped groove, which accelerates the circulation and spread of the fabric and avoids the fabric from knotting and tangling.

[0031] In this embodiment, one end of the guide plate 3 is fixedly connected to the storage cloth plate 2, and the other end is welded to the inner wall of the cylinder body 1. The angle between the guide plate 3 and the storage cloth plate 2 is 15°-30°.

[0032] In this embodiment, the storage plate 2 divides the inner cavity of the cylinder body 1 into an upper storage trough 11 and a lower liquid accumulation chamber 12. The storage trough 11 and the liquid accumulation chamber 12 are connected by a through hole 21 in the storage plate 2.

[0033] Specifically, the opening and closing size of the through hole 21 is automatically adjusted according to the liquid level of the dye in the liquid accumulation chamber 12. For example, when the liquid level is too low, the diameter of the through hole 21 is reduced by using the adjustable through hole 21 component until the through hole 21 is closed, blocking the flow of dye, so that the dye in the liquid accumulation chamber 12 can quickly flow back to the fabric storage tank 11 through the circulation channel 6, maintaining only a small amount of circulation.

[0034] In this embodiment, a circulation pump interface 5 is provided at the bottom of the main body 1 of the cylinder. One end of the circulation pump interface 5 is connected to the liquid accumulation chamber 12, and the other end is connected to an external circulation pump.

[0035] Specifically, the circulation pump interface 5 is also connected to a circulation channel 6, which has an arc-shaped structure. The other end of the circulation channel 6 is connected to the side wall of the main body 1 and communicates with the fabric storage tank 11. When the dye liquor flows within the circulation channel 6, centrifugal force is generated due to the arc-shaped structure of the circulation channel 6, accelerating the circulation of the dye liquor. Simultaneously, the dye liquor enters the fabric storage tank 11 through the through-holes 21 on the fabric storage plate 2, contacting the fabric for dyeing.

[0036] In this embodiment, the inner wall of the circulation channel 6 is covered with a microporous filter membrane 6131 with a pore size of 0.1-0.5 mm.

[0037] Specifically, the microporous filter membrane 6131 on the inner wall of the circulation channel 6 is made of PTFE material, and the pore size of the microporous filter membrane 6131 is preferably 0.3mm. The microporous filter membrane 6131 can intercept fibrous impurities, prevent the through holes 21 from being blocked, and ensure long-term operational stability.

[0038] In this embodiment, multiple sets of liquid level sensors 7 are provided on the inner wall of the main body 1. The multiple sets of liquid level sensors 7 are linked with the adjustable through hole 21 assembly and the circulation pump interface 5 through the controller to form a closed-loop control system.

[0039] Specifically, the liquid level sensor 7 is a capacitive non-contact sensor with a detection accuracy of ±0.5mm; the controller has a built-in PID algorithm, which is a publicly known technology and will not be described in detail here. The controller is programmed to automatically control the orifice size of the adjustable through-hole 21 component and the working status of the circulation pump based on the data collected by the liquid level sensor 7, thereby maintaining the liquid level in the fabric storage tank 11 within ±2cm of the fabric surface.

[0040] During the dyeing process of the fabric, the liquid level sensor 7 monitors the liquid level in real time. When the liquid level is lower than the set value, the controller controls the adjustable through hole 21 component to close the aperture of the through hole 21, so that the dye liquid in the liquid accumulation chamber 12 can quickly flow back to the fabric storage tank 11. At the same time, the circulation pump is started to replenish the dye liquid through the circulation channel 6 at a flow rate of 200L / min until the liquid level is restored to the set range.

[0041] It is worth noting that during the dyeing process, the dye solution is applied from the fabric storage tank 11 of the main body 1. When the dye solution is poured in, the amount of dye solution input and the number of cycles are controlled according to the amount of fabric used. The following results are obtained based on multiple actual experiments.

[0042] Comparative analysis (traditional tube body) and test comparison of the embodiments of this application:

[0043]

[0044] The workflow of this utility model is as follows:

[0045] Preparation: Place the fabric to be dyed into the fabric storage tank 11 in a certain quantity and manner. According to the type, quantity and dyeing requirements of the fabric, preset the initial aperture of the adjustable through-hole 21 component, the operating parameters of the circulation pump and the control range of the liquid level through the controller.

[0046] Dyeing Process: The dyeing machine is started, and the circulation pump begins operation, drawing the dye liquor from the accumulation chamber 12 to the storage tank 11 through the circulation channel 6. As the dye liquor flows within the circulation channel 6, the arc-shaped structure generates centrifugal force, accelerating the circulation. Simultaneously, the dye liquor enters the storage tank 11 through the through-holes 21 on the storage plate 2, contacting the fabric for dyeing. During the dyeing process, the liquid level sensor 7 monitors the liquid level data in the storage tank 11 in real time and transmits the data to the controller. The controller automatically adjusts the aperture size of the adjustable through-hole 21 component based on the preset liquid level range and the real-time liquid level data. When the liquid level is too high, the aperture of the through-hole 21 is increased, reducing the amount of dye liquor entering the storage tank 11; when the liquid level is too low, the aperture of the through-hole 21 is decreased, allowing more dye liquor to enter the storage tank 11.

[0047] Dye liquor circulation and utilization: After the dye liquor comes into full contact with the fabric in the storage tank 11, it flows back to the collection chamber 12 through the through-hole 21 of the storage plate 2. Under the action of the guide plate 3, the dye liquor flows along the guide fins 31 and the turbulence grooves 311, forming a directional dye liquor flow field and reducing the retention of dye liquor in the storage tank 11. The circulation pump continuously pumps the dye liquor in the collection chamber 12 to the storage tank 11, realizing the recycling of the dye liquor. Due to the closed-loop control system, the dye liquor can be allocated on demand according to the dyeing requirements of the fabric, improving the utilization rate of the dye liquor and reducing dye liquor waste and water consumption.

[0048] Dyeing complete: Once the dyeing has reached the predetermined time and effect, stop the circulation pump and drain the dye solution. Remove the dyed fabric for subsequent processing steps.

[0049] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
