Description

Technical Field

[0001] This utility model relates to the field of mixing tank technology, specifically a concentrated water mixing tank for dyeing workshops. Background Technology

[0002] To rationally recycle and reduce water waste, it is necessary to collect and discharge concentrated wastewater again, transport it to the dyeing and finishing workshop, mix it with tap water, and then use it as dyeing and finishing water. The dyeing and finishing workshop is the core production link of the textile printing and dyeing industry. It generates a large amount of wastewater in processes such as fabric dyeing, bleaching, and finishing. Among them, "concentrated wastewater" usually refers to wastewater that still contains high concentrations of dyes, auxiliaries, salts, and a small amount of fiber impurities after preliminary sedimentation and filtration. It is characterized by high color, high COD, complex composition, and strong corrosiveness. In order to achieve the resource-based reuse or standard discharge of concentrated wastewater, it is necessary to first mix the concentrated wastewater with clean water, neutralizing agents, or decolorizing agents in a mixing tank to adjust the water quality parameters.

[0003] Chinese Utility Model Patent Publication No. CN212387896U discloses a novel concentrated water tank. The specification of this novel concentrated water tank states that the outer wall of the lower treatment zone has concave grooves on both sides, each groove containing a glass cover and an ultraviolet germicidal lamp. This design facilitates operation during production, significantly reduces purification time at the factory, and offers high production efficiency. However, this novel concentrated water tank lacks a reinforcing structure. When water is added, the tank is prone to deformation due to water flow impact, leading to leakage. Furthermore, the lack of a drainage structure makes it difficult for the concentrated water to drain quickly after mixing, potentially causing residue inside the tank and affecting subsequent normal use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a concentrated water mixing tank for dyeing and bleaching workshops. It can effectively solve the problems in the prior art, where the tank body is easily deformed due to water flow impact during water injection, resulting in leakage. In addition, the lack of a drainage structure makes it difficult for the concentrated water inside to be quickly discharged after mixing, which can easily lead to residue inside the tank and affect subsequent normal use.

[0005] The technical solution adopted by this utility model is: a concentrated water mixing tank for dyeing workshop, including a base and a tank body, multiple side plates are fixedly installed on the outer edge of the tank body, and fixed plates are fixedly installed at the diagonal of the multiple side plates. A feeding component, a limiting component and a discharge component are fixedly installed inside the tank body, and a top cover is provided at the end of the tank body away from the base. The feeding assembly includes a feeding pipe and a discharging pipe. A feeding flange is fixedly installed at the end of the feeding pipe away from the housing. A first mounting flange is fixedly installed at the end of the feeding pipe close to the housing. A second mounting flange is fixedly installed at the end of the discharging pipe close to the first mounting flange. The limiting component includes a limiting frame and a mounting groove, wherein the limiting frame is snapped with a stop frame and a baffle.

[0006] Preferably, a positioning bolt is fixedly installed at the end of the fixing plate away from the box body, and the positioning bolt passes through the fixing plate and the side plate and extends into the interior of the box body.

[0007] The above technical solution uses fixed plates and side plates, as well as diagonally distributed fixed plates, in conjunction with positioning bolts that penetrate the side plates and the tank body to form a rigid fixing structure of "diagonal tension". This enhances the overall anti-deformation ability of the water tank, can adapt to the high liquid level and heavy load conditions of concentrated water in the dyeing workshop, prevents leakage of the tank body, and avoids easy deformation of the tank body.

[0008] Preferably, the feed pipe passes through the box body and the side plate and extends to the outer edge, the first mounting flange and the second mounting flange are adapted to each other, and a solenoid valve is provided at the end of the feed pipe away from the box body.

[0009] With the above technical solution, the feed pipe passes through the box body and the side plate, and the mounting flange one and mounting flange two are sealed together. The feed rate of concentrated water is controlled by solenoid valve one, which can prevent concentrated water leakage.

[0010] Preferably, the feeding components are provided in two identical sets, and the two sets of feeding components are symmetrically distributed about the center line of the box.

[0011] With the above technical solution, two sets of feeding components are symmetrically distributed along the center line of the tank, allowing different concentrations of water to be injected simultaneously or proportionally from both sides. The water flow counteracts the water flow to enhance the mixing effect. The water flow collides and diffuses in the middle of the tank, which can accelerate the fusion of solutions of different concentrations and reduce mixing dead zones. At the same time, one set can be selected to feed concentrated water and the other set to feed raw water, which can also improve the mixing efficiency. The selection can be made according to the actual working conditions, thus increasing the versatility of the overall device.

[0012] Preferably, an installation groove is provided at the inner edge of the limiting frame, and a baffle is snapped into the limiting frame through the installation groove. A through groove is provided through the baffle from top to bottom. The through groove has a "regular hexagonal" cross-section, and multiple through grooves are provided and are distributed at equal intervals.

[0013] With the above technical solution, after the concentrated water enters the tank, it is first initially guided by the baffle frame, and then divided into multiple fine water streams by multiple sets of regular hexagonal channels of the baffle. The water streams collide and swirl with each other at the outlet of the channel, which can form strong turbulence, accelerate molecular diffusion, replace the stirring mechanism, and reduce energy consumption.

[0014] Preferably, the discharge assembly includes a discharge pipe, and a second through groove is provided at one end of the discharge pipe near the housing. A diversion block is fixedly installed along the edge inside the housing. The height of the second through groove is flush with the height of the diversion block, and the side of the diversion block near the second through groove is designed to be inclined.

[0015] The above technical solution utilizes gravity through the inclined design of the diversion block to allow the concentrated water in the tank to converge along the inclined surface to the second channel. Since the second channel is located at the lowest point of the tank and is flush with the diversion block, the concentrated water at the lowest liquid level can also be discharged, avoiding the presence of residue inside the tank during discharge.

[0016] Preferably, a connecting flange is fixedly installed at the end of the discharge pipe away from the housing, and a second solenoid valve is fixedly installed at the end of the discharge pipe away from the housing.

[0017] The above technical solution achieves a sealed connection with external pipelines through the connecting flange of the discharge pipe, and the discharge is controlled by a solenoid valve, which can improve the convenience and sealing of the discharge operation and meet the continuous production needs of the dyeing and finishing workshop.

[0018] Compared with the prior art, this utility model provides a concentrated water mixing tank for dyeing workshops, which has the following beneficial effects: 1. The dyeing workshop uses a concentrated water mixing tank. Two sets of feeding components are symmetrically distributed along the center line of the tank. Different concentrated waters can be injected from both sides simultaneously or proportionally. The water flow counter-current enhances the mixing effect. The water flow collides and diffuses in the middle of the tank, which can accelerate the fusion of solutions of different concentrations and reduce mixing dead zones. At the same time, one set can be selected to select concentrated water and the other set can be selected to select raw water, which can also improve the mixing efficiency. The selection can be made according to the actual working conditions, which increases the versatility of the overall device. 2. The concentrated water mixing tank in this dyeing workshop is formed by fixed plates and side plates, as well as diagonally distributed fixed plates, with positioning bolts penetrating the side plates and the tank body to form a rigid fixed structure of "diagonal tension". This enhances the overall anti-deformation ability of the tank, can adapt to the high liquid level and heavy load conditions of concentrated water in the dyeing workshop, prevents leakage of the tank body, and avoids easy deformation of the tank body. 3. The concentrated water mixing tank in this dyeing workshop uses gravity through the inclined design of the diversion block to allow the concentrated water in the tank to converge along the inclined surface to the second channel. With the second channel set at the lowest point of the tank and flush with the diversion block, the concentrated water at the lowest liquid level can also be discharged, avoiding the presence of residue inside the tank during discharge.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: As Figure 1-8 As shown, the present invention provides a concentrated water mixing tank for a dyeing workshop, including a base 1 and a tank body 5. Multiple side plates 2 are fixedly installed on the outer edge of the tank body 5, and fixed plates 3 are fixedly installed at the diagonal corners of the multiple side plates 2. A feeding assembly 7, a limiting assembly 8 and a discharge assembly 9 are fixedly installed inside the tank body 5. A top cover 6 is provided at the end of the tank body 5 away from the base 1. The feeding assembly 7 includes a feeding pipe 701 and a discharging pipe 705. A feeding flange 702 is fixedly installed at the end of the feeding pipe 701 away from the housing 5, and a mounting flange 703 is fixedly installed at the end of the feeding pipe 701 close to the housing 5. A mounting flange 704 is fixedly installed at the end of the discharging pipe 705 close to the mounting flange 703. The limiting component 8 includes a limiting frame 801 and a mounting slot 802. The limiting frame 801 is snapped with a stop frame 803 and a baffle 804.

[0023] Specifically, a positioning bolt 4 is fixedly installed at the end of the fixing plate 3 away from the box body 5. The positioning bolt 4 passes through the fixing plate 3 and the side plate 2 and extends into the interior of the box body 5. The advantage is that the fixing plate 3, the side plate 2, and the diagonally distributed fixing plates 3, together with the positioning bolt 4 passing through the side plate 2 and the box body 5, form a rigid fixing structure of "diagonal tension", which enhances the overall anti-deformation ability of the water tank, can adapt to the high liquid level and heavy load conditions of concentrated water in the dyeing workshop, prevent the box body 5 from leaking, and avoid the box body 5 from being easily deformed.

[0024] Specifically, the feed pipe 701 passes through the housing 5 and the side plate 2 and extends to the outer edge. The mounting flange 703 and the mounting flange 704 are compatible. A solenoid valve 706 is installed at the end of the feed pipe 701 away from the housing 5. The advantage is that the feed pipe 701 passes through the housing 5 and the side plate 2, and the mounting flange 703 and the mounting flange 704 are sealed together. The feed rate of concentrated water is controlled by the solenoid valve 706, which can prevent concentrated water leakage.

[0025] Specifically, the feeding components 7 are provided in two identical sets, which are symmetrically distributed about the center line of the housing 5. The advantage is that by symmetrically distributing the two sets of feeding components 7 along the center line of the housing 5, different concentrated waters can be injected from both sides simultaneously or proportionally. The water flow counteracts and enhances the mixing effect. The water flow collides and diffuses in the middle of the housing 5, which can accelerate the fusion of solutions of different concentrations and reduce mixing dead zones. At the same time, one set can be selected to select concentrated water and the other set to select raw water, which can also improve the mixing efficiency. The selection can be made according to the actual working conditions, thereby increasing the versatility of the overall device.

[0026] Example 2: Figure 2-8 As shown, this is an improvement on the previous embodiment.

[0027] Specifically, an installation groove 802 is provided at the inner edge of the limiting frame 801, and a baffle 803 is snapped into the limiting frame 801 through the installation groove 802. A through groove 805 is provided through the baffle 804 from top to bottom. The through groove 805 has a "regular hexagonal" cross-section. Multiple through grooves 805 are provided and are distributed at equal intervals. The advantage is that after the concentrated water enters the tank 5, it is first initially guided by the baffle 803, and then divided into multiple fine water streams by the multiple sets of regular hexagonal through grooves 805 of the baffle 804. The water streams collide and swirl with each other at the outlet of the through groove, which can form strong turbulence, accelerate molecular diffusion, replace the stirring mechanism, and reduce energy consumption.

[0028] Specifically, the discharge assembly 9 includes a discharge pipe 901. A through groove 902 is provided at one end of the discharge pipe 901 near the tank 5. A diversion block 10 is fixedly installed along the edge inside the tank 5. The height of the through groove 902 is flush with the height of the diversion block 10. The side of the diversion block 10 near the through groove 902 is designed with an inclination. The advantage is that by using the gravity effect of the inclination design of the diversion block 10, the concentrated water in the tank 5 can be gathered along the inclination to the through groove 902. In addition, the through groove 902 is set at the lowest point of the tank 5, flush with the diversion block 10, so that the concentrated water at the lowest liquid level can also be discharged, avoiding the presence of residue inside the tank 5 during discharge.

[0029] Specifically, a connecting flange 903 is fixedly installed at the end of the discharge pipe 901 away from the housing 5, and a solenoid valve 904 is fixedly installed at the end of the discharge pipe 901 away from the housing 5. The advantage is that the connecting flange 903 of the discharge pipe 901 achieves a sealed connection with the external pipeline, and the discharge is controlled by the solenoid valve 904, which can improve the convenience and sealing of the discharge operation and meet the continuous production needs of the dyeing and finishing workshop.

[0030] Working Principle: During use, the fixed plate 3, side plate 2, and diagonally distributed fixed plates 3, along with positioning bolts 4, penetrate the side plate 2 and the tank body 5, forming a rigid "diagonally tightened" fixing structure. This enhances the overall deformation resistance of the water tank, allowing it to adapt to high liquid levels and heavy loads in dyeing workshops, preventing leakage from the tank body 5 and avoiding easy deformation. The feed pipe 701 penetrates the tank body 5 and side plate 2, and the mounting flange 1 703 and mounting flange 2 704 are sealed together. The feed rate of concentrated water is controlled by solenoid valve 1 706, preventing leakage. Two sets of feed components 7 are symmetrically distributed along the center line of the tank body 5, allowing different concentrated waters to be injected simultaneously or proportionally from both sides. The water flow counter-current enhances the mixing effect. The water flow collides and diffuses in the middle of the tank body 5, accelerating the fusion of solutions of different concentrations and reducing mixing dead zones. Alternatively, one set can be selected to feed concentrated water and the other to feed raw water, further improving mixing efficiency. The selection can be made according to the actual working conditions to improve the versatility of the overall device. After the concentrated water enters the tank 5, it is first initially guided by the baffle frame 803, and then divided into multiple fine water streams by the multiple sets of regular hexagonal channels 805 of the baffle 804. The water streams collide and swirl with each other at the outlet of the channel, which can form strong turbulence, accelerate molecular diffusion, replace the stirring mechanism, and reduce energy consumption. The inclined design of the diversion block 10 utilizes gravity to make the concentrated water in the tank 5 converge along the inclined surface to the channel 902. With the channel 902 set at the lowest point of the tank 5 and flush with the diversion block 10, the concentrated water at the lowest liquid level can also be discharged, avoiding the presence of residue inside the tank 5 during discharge. The connection flange 903 of the discharge pipe 901 achieves a sealed connection with the external pipeline. With the solenoid valve 904 controlling the discharge, the convenience and sealing of the discharge operation can be improved, which can meet the continuous production needs of the dyeing workshop.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
