Description

Technical Field

[0001] This invention relates to the field of dye storage device technology, and more specifically to a liquid dye storage device with premixing function. Background Technology

[0002] Liquid dye storage devices are specialized equipment designed for the textile, printing and dyeing, and chemical industries to safely and stably store various liquid dyes (such as reactive, disperse, and acid dyes), dye mother liquors, and auxiliaries. Their core functions are corrosion prevention, sedimentation prevention, temperature control, contamination prevention, and secure sealing to ensure stable dye quality and production safety.

[0003] Current liquid dye storage devices still have the following problems: 1. In existing storage devices, under long-term static or conventional stirring conditions, high-concentration heavy dyes tend to settle at the bottom of the tank due to differences in dye specific gravity and gravity, resulting in uneven concentration between the upper and lower layers and affecting the quality of the dye within the tank. Furthermore, in continuous production, the lack of interconnectivity between multiple independent storage tanks leads to color differences between dyes in different tanks, restricting the yield and quality stability of continuous production.

[0004] 2. In devices with preliminary mixing or circulation functions, the injection and confluence flow of dyes in the mixing chamber are fixed, which easily leads to laminar flow in local mixing areas. Dyes of different concentrations are difficult to undergo intense turbulent confluence, resulting in low mixing efficiency and affecting the mixing effect.

[0005] 3. Chemical agents or auxiliaries are usually added during the dye preparation process. However, the existing dosing system is mostly an independently operating quantitative dripping structure, which cannot automatically adjust the amount of agent injected according to the real-time operating status of the stirring mechanism. This leads to excessive accumulation of agents at low speeds and insufficient agent supply at high speeds, resulting in an imbalance in the addition ratio.

[0006] Therefore, it is necessary to propose a liquid dye storage device with premixing function to solve the above problems. Summary of the Invention

Subsequently, it mixes with reagents, and finally, the uniformly mixed liquid dye is transported back to the center of the tank.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] The conventional components and key load-bearing components in this case are selected in accordance with standards in terms of material selection, heat treatment process and structural dimensions to ensure that they have sufficient strength, stiffness and fatigue resistance under rated load and expected working conditions. These are all conventional design considerations well known to those skilled in the art.

[0026] Depend on Figures 1 to 8The invention includes a storage tank 101 with a feed inlet on its side wall for adding materials into the tank. A hollow stirring rod 102 is rotatably connected inside the storage tank 101 to reduce weight during stirring, while the hollow interior allows for liquid flow. A lower stirring blade 103 is connected to the outer wall of the stirring rod 102, located in the middle of the liquid, and provides pre-stirring. Pre-stirring is a continuous homogenization process performed on the dye in the tank during the dye storage stage and before it is conveyed to subsequent processes. This maintains stable dye concentration and color, prevents sedimentation and stratification, and ensures that the discharged material meets usage requirements. Ordinary stirring is mostly used in on-site material mixing and reaction preparation processes. A circulation pump 104 is installed outside the storage tank 101. The circulation pump 104 is connected to an inlet pipe 105 and an outlet pipe 106 located at the top and bottom of the storage tank 101, respectively. The circulation pump 104 draws in the dye from the bottom of the storage tank 101 and returns it to the tank body, thereby achieving pre-mixing of the dye and preventing stratification. A mixing tank 107 is connected to the top of the storage tank 101, and the top of the stirring rod 102 extends into the mixing tank 107. A oscillating assembly is connected to the inner wall of the mixing tank 107, and the outlet pipe 106 is connected to the oscillating assembly. The dye from the circulation pump 104 enters the mixing tank 107 through the outlet pipe 106. The oscillating assembly changes the flow direction of the dye, preventing a fixed flow direction from affecting the mixing effect. The bottom of the mixing tank 107 is connected to a liquid inlet assembly, which draws in the upper layer of dye from the liquid surface and transports it into the mixing tank 107. Since the water inlet of the circulating pump 104 is located at the bottom of the tank, the dye entering the pump is of high concentration, while the liquid inlet assembly draws in the lower concentration, thinner liquid dye from the upper layer of the liquid. The two will mix in the mixing tank 107 to improve the uniformity of the dye inside. The lower stirring blade 103 has a liquid outlet hole at its end, which is used to discharge the mixed dye liquid. The hole at the end of the lower stirring blade 103 is a well-established existing structure and will not be described in detail here. In one embodiment, the blade of the lower stirring blade 103 is hollow, and the edge of the blade has a hole for discharging liquid. The mixing tank 107 is connected to an inner tank 108. The outer wall of the stirring rod 102 is provided with a liquid inlet hole 109 located inside the inner tank 108. The liquid inlet hole 109 is connected to the liquid outlet hole through the inside of the stirring rod 102. After the liquid dye in the mixing tank 107 is mixed, it enters the inner tank 108 and enters the hollow stirring rod 102 from the liquid inlet hole 109 at the bottom of the inner tank 108. During the downward flow, it passes through the lower stirring blade 103 and flows out from the liquid outlet hole at the end of the lower stirring blade 103.

[0027] To reduce variations between batches of dye during use, additives or chemicals are added to the tank. The following structure provides a method for uniformly mixing the added chemicals with the circulating liquid, serving as a pre-mixing agent: A conical frame 110 is rotatably connected to the top of the stirring rod 102. A chemical chamber 111, communicating with the conical frame 110, is located at the top of the stirring rod 102. A material pipe 112 is connected to the top of the conical frame 110, and the material pipe 112 is externally connected to a chemical or additive supply device. Chemical agents can enter the conical frame 110 through the material pipe 112. A flow component is installed within the conical frame 110, controlling the amount of chemical agent added before it enters the chemical chamber 111. A chemical hole 113, communicating with the chemical chamber 111, is provided on the outer wall of the stirring rod 102, allowing the chemical agent to enter the inner tank 108 and mix with the dye inside. When no chemical agent is needed, the flow component closes, blocking the flow of the chemical agent.

[0028] When low-concentration dyes and high-concentration dyes are mixed in mixing tank 107, uneven mixing due to laminar flow can occur because the dye outlet position is fixed. The following provides a structure to change the liquid flow direction and thus improve the mixing effect: Specifically, an annular frame 201 is connected to the inner wall of the mixing tank 107. The oscillating assembly includes oscillating rods 202 arranged circumferentially inside the annular frame 201. The oscillating rods 202 reciprocate within the annular frame 201. A guide plate 203 is connected to the outer wall of the oscillating rods 202. High-concentration dyes enter the annular frame 201 through the outlet pipe 106. The rotating oscillating rods 202 change the liquid flow direction through the guide plate 203, making the liquid mix more evenly and improving the mixing effect. The top of the ring frame 201 is connected to a housing 204. A gear ring 205 is rotatably connected inside the housing 204. A gear 206 meshing with the gear ring 205 is connected to the top of the swing rod 202. The housing 204 protects the internal gear ring 205 and gear 206, preventing liquid from affecting the stability of the components. The swing rod 202 is externally driven by a drive structure. This drive structure rotates the swing rod 202, which in turn drives the gear ring 205 to rotate via the gear 206 at its top. The rotating gear ring 205 drives multiple gears 206 to rotate, allowing multiple guide plates 203 to swing synchronously.

[0029] When the stirring rod 102 rotates, the oscillating assembly needs to move synchronously to improve the mixing effect. Simultaneously, the oscillation speed needs to be automatically adjusted according to the rotation speed. The following provides a structure where the oscillating assembly moves according to the rotation speed of the stirring rod 102: Specifically, an action chamber 207 is provided at the top of the mixing tank 107 to prevent the internal structure from being affected by the liquid. A sleeve 208 extending into the action chamber 207 is connected to the top of any of the oscillating rods 202, and the sleeve 208 is rotatably connected to the bottom wall of the action chamber 207. A cavity is provided at the top of the sleeve 208, and a lifting rod 209 is slidably connected within the cavity. The lifting rod 209 and the sleeve 208 are coaxially arranged. An inclined groove 210 is provided on the inner wall of the cavity. An annular plate 211 located within the action chamber 207 is connected to the top of the stirring rod 102. A curved groove 212 is provided on the outer annular surface of the annular plate 211, and the curved groove 212 is wavy. Both the curved slide groove 212 and the inclined slide groove 210 are slidably connected to sliding pins located on the outer wall of the lifting rod 209. When the annular plate 211 drives the curved slide groove 212 to rotate, the sliding pin at the top of the lifting rod 209 slides within the curved slide groove 212, thereby causing the lifting rod 209 to move up and down reciprocally. The sliding pin at the bottom of the lifting rod 209 slides within the inclined slide groove 210, causing the sleeve 208 to rotate. Due to the up and down reciprocating movement of the lifting rod 209, the sleeve 208 drives the swing rod 202 to swing back and forth.

[0030] When adding reagents, different amounts require different stirring speeds to avoid excessively low stirring speeds that could affect the mixing effect of the reagents and dyes. The following provides a structure for controlling the amount of reagent added: Specifically, an inner ring tube 301 is slidably connected to the inner wall of the conical frame 110. Sealing structures are provided at both ends of the outer wall of the inner ring tube 301 to improve the seal between it and the inner wall of the conical frame 110. The liquid inlet assembly includes a conical plug 302 connected to the inner wall of the inner ring tube 301. A gap is provided between the conical plug 302 and the inner ring tube 301 for the passage of liquid dye. The conical plug 302 and the conical frame 110 are fitted together; increasing the distance between the conical plug 302 and the conical frame 110 increases the amount of reagent that can pass through. Since the conical plug 302 is located inside, it is inconvenient to control its movement. Therefore, a vertically arranged adjustment groove 303 is provided on the outer wall of the stirring rod 102. A connecting post 304 passing through the adjustment groove 303 is connected to the outer ring surface of the inner ring tube 301. The connecting post 304 extends outward and is externally connected to a lifting drive structure. The lifting drive structure drives the inner conical plug 302 to move up and down through the inner ring tube 301. The inner ring tube 301 has a certain length, and the connecting post 304 is located in the middle of the outer wall of the inner ring tube 301. Regardless of whether the conical plug 302 is at the top or the bottom, one end of the inner ring tube 301 can cover the adjustment groove 303 to prevent the internal medicine from leaking out of the adjustment groove 303. For example, when the conical plug 302 is at the bottom, the amount of medicine entering is the largest. The conical plug 302 drives the connecting column 304 to the bottom of the adjustment groove 303 through the inner ring tube 301. At this time, the top of the inner ring tube 301 will cover the adjustment groove 303 to prevent the medicine inside from leaking from the adjustment groove 303. The sealing ring structure at both ends of the outer wall of the inner ring tube 301 is used to increase the sealing performance.

[0031] Different dosages of the agent require different rotation speeds. When the dosage is large, a faster rotation speed is needed to improve mixing efficiency; when the dosage is small, a lower rotation speed is needed to reduce energy consumption. The following provides a structure in which the dosage and rotation speed are coordinated: Specifically, a guide frame 305 is connected between the stirring rod 102 and the annular plate 211. A counterweight 306 is slidably connected to the outer wall of the guide frame 305. A lifting frame 307 located above the guide frame 305 is slidably connected to the top of the stirring rod 102. The lifting frame 307 slides up and down on the outer wall of the stirring rod 102. The lifting frame 307 and the counterweight 306 are connected by a connecting rod 308. The lifting frame 307 and the guide frame 305 are connected by a compression spring. The higher the rotation speed of the stirring rod 102, the greater the centrifugal force on the counterweight 306. The lifting frame 307 moves downward through the connecting rod 308, at which time the spring between the lifting frame 307 and the guide frame 305 is compressed. The inner wall of the lifting frame 307 is connected to the connecting column 304. The downward-moving lifting frame 307 drives the inner ring pipe 301 and the conical plug 302 to move downward through the connecting column 304, thereby increasing the throughput of the medicine and automatically controlling the addition of medicine according to the rotation speed. When the stirring rod 102 rotates at a low speed, it is insufficient to overcome the spring preload, the spring remains stationary, and the medicine supply passage is closed. Only when the rotation speed reaches the set threshold and the centrifugal force is greater than the spring force will the spring be compressed and deformed, thereby performing the medicine addition action, which has the function of not adding medicine at low speed.

[0032] When high-concentration dyes, low-concentration dyes, and reagents come into contact in the inner tank 108, uneven mixing can occur, affecting the quality of the dyes within the tank. The following structure improves the mixing effect: Specifically, the stirring rod 102, located within the conical frame 110, is connected to a stirring blade 401. The stirring rod 102 drives the stirring blade 401 to rotate, improving the mixing effect within the inner tank 108. In one embodiment, the stirring blade 401 has a reagent hole 113 communicating with the reagent chamber 111. When the stirring blade 401 rotates, the reagent is thrown into the dye, improving the uniformity of reagent addition. Guide vanes are provided on the outer wall of the conical frame 110 and the inner wall of the mixing tank 107. As the low-concentration and high-concentration dyes flow upwards, their direction is changed by the guide vanes, thereby improving the mixing effect. The stirring rod 102 is internally connected to staggered blades 402. The staggered blades 402 are blade structures arranged alternately inside a static mixing tube to improve the mixing effect of the fluid. This is an existing and mature structure, and will not be described in detail here. The stirring rod 102 is internally connected to a partition plate 403 that separates the agent chamber 111, which serves to separate and block the flow.

[0033] When high-concentration dyes and low-concentration dyes need to be mixed, the dye at the top of the liquid needs to be drawn in to facilitate mixing. The following provides a structure for drawing in low-concentration dye: Specifically, refer to... Figure 5 , Figure 5 The black line segment with arrows indicates the direction of liquid flow. The liquid inlet assembly includes a rotating disk 501 connected to the outer wall of the stirring rod 102. The rotating disk 501 is located above the lower stirring blade 103 and below the liquid surface. An opening is provided at the bottom axis of the rotating disk 501, allowing external liquid to enter the rotating disk 501. An upper stirring blade 502 is connected to the outer wall of the rotating disk 501, which can stir the upper part of the liquid. The outer wall of the stirring rod 102 is connected to a first centrifugal blade 503 and a second centrifugal blade 504. The first centrifugal blade 503 is located inside the rotating disk 501. A baffle 505 is connected above the first centrifugal blade 503. There is a distance between the edge of the baffle 505 and the inner wall of the rotating disk 501. When the first centrifugal blade 503 rotates with the rotating disk 501, the dye at the bottom is drawn in at the axis. The dye moves towards the edge due to the action of the blade. Because there is a distance between the baffle 505 at the top and the inner wall of the rotating disk 501, the dye moves upward from the edge and then enters the top of the rotating disk 501. An intermediate pipe 506 connects the rotating disk 501 and the mixing tank 107. The interior of the rotating disk 501 is connected to the intermediate pipe 506. The dye located in the rotating disk 501 moves upward and enters the mixing tank 107 through the intermediate pipe 506. In one embodiment, the second centrifugal blade 504 is located between the mixing tank and the conical frame 110. The dye entering the mixing tank 107 is moved upward again by the action of the second centrifugal blade 504 to improve the dye delivery capacity.

[0034] The inlet pipe 105 of the circulating pump 104 is located at the bottom of the storage tank 101. Due to its fixed position, only dye around the inlet pipe 105 can enter the circulation. Heavy dyes that have settled at the bottom due to gravity have difficulty entering the circulation. The following is a structure to avoid the deposition of heavy dyes at the bottom: Specifically, an inlet pan 601 located at the bottom of the storage tank 101 is connected to the outer wall of the stirring rod 102. The inlet pan 601 rotates with the stirring rod 102. A horizontal pipe 602 is connected to the outer wall of the inlet pan 601, extending outward to increase the range of action. An air suction groove 603 is provided on the outer wall of the horizontal pipe 602. The air suction groove 603 is located on one side of the rotation direction of the horizontal pipe 602. When the horizontal pipe 602 rotates, the heavy dyes at the bottom will enter the inlet pan 601 through the air suction groove 603. The bottom of the storage tank 101 is connected to a water outlet plate 604, which is rotatably connected to a stirring rod 102. The outer wall of the stirring rod 102 has a first through hole 605 located in the water inlet plate 601 and a second through hole 606 located in the water outlet plate 604. The water outlet plate 604 is connected to a water inlet pipe 105. Liquid entering the water inlet plate 601 enters the stirring rod 102 through the first through hole 605, then enters the water outlet plate 604 through the second through hole 606, and finally enters the water inlet pipe 105. A partition plate 403 is also provided above the first through hole 605 to prevent liquid from flowing upwards.

[0035] The high-concentration dye at the bottom of the tank is removed, and the low-concentration dye at the top of the liquid is also removed. The uniform liquid after mixing in the mixing tank 107 flows out from the stirring blade 103 in the middle position, which improves the uniformity of the dye in the storage tank 101.

[0036] In practice, multiple storage tanks 101 are typically used to store dye. Since each tank is separate, color differences can occur within each tank. To address this, a structure is provided that connects multiple tanks in series for circulation: Specifically, an annular frame 201 is connected to an annular pipe 114 on its outer side. Multiple connecting pipes on the annular pipe 114 connect to the annular frame 201, allowing the dye to enter the annular frame 201 from multiple angles, preventing excessive local liquid inflow. The annular pipe 114 is connected to an outlet pipe 106, which is connected to an electrically controlled three-way valve 115. The electrically controlled three-way valve 115 has an external control structure, and another port of the valve is connected to a circulation pipe 118. The circulation pipe 118 connects to the annular pipe 114 in the next storage tank 101, thus connecting the multiple storage tanks 101 in series. A circulation pump 104 is used to transport the dye from one tank to the next, allowing the dye to circulate within multiple tanks.

[0037] By controlling the opening state of the electrically controlled three-way valve 115, it is possible to switch between self-circulation and multi-tank circulation.

[0038] To drive the stirring rod 102 to rotate stably and provide a position for the water outlet tray 604 while avoiding interference, the following driving structure for the stirring rod 102 is provided: Specifically, a motor 116 is connected to the bottom of the storage tank 101, and a fixed bracket is provided on the motor 116 to support the motor and accommodate the water outlet tray 604. The output end of the motor 116 is connected to the stirring rod 102, and a dye outlet pipe 117 is connected to the bottom of the outer wall of the storage tank 101 for discharging the dye.

[0039] When using this invention, the storage tank 101 stores the dye, the motor 116 is started, and the motor 116 drives the lower stirring blade 103 to pre-stir in the tank through the stirring rod 102, so that the liquid inside flows and the dye precipitates.

[0040] The circulation pump 104 is started, and the stirring rod 102 drives the horizontal pipe 602 to rotate at the bottom via the water inlet plate 601, allowing the heavy dye at the bottom to enter the mixing tank 107 through the circulation pump 104. When the liquid inlet assembly rotates, it draws in the liquid above the dye, allowing the low-concentration dye and the high-concentration dye to mix in the mixing tank 107. The oscillating assembly oscillates back and forth, changing the flow direction of the high-concentration dye, thereby improving the mixing effect of the liquid.

[0041] After mixing, the liquid enters the inner tank 108 and flows into the stirring rod 102 through the liquid inlet 109 at the bottom of the inner tank 108. It then flows out through the liquid outlet at the end of the lower stirring blade 103, representing a uniform dye mixture of high and low concentration dyes. When chemical agents need to be added to the dye, the stirring rod 102 rotates at an increased speed. At this time, the liquid inlet assembly starts operating. The higher the rotation speed, the more chemicals are added. The added chemicals mix with the dye within the inner tank 108 and flow with it.

[0042] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
