Description

Technical Field

[0001] The invention relates to the field of multi-stage wastewater treatment, in particular to cold transfer printing equipment with wastewater circulation treatment. Background Art

[0002] Transfer printing is an important part of the printing and dyeing industry. Traditional heat transfer printing requires printing paper with disperse dye patterns to be transferred to the fabric under high temperature and a certain pressure. This process has many disadvantages, so cold transfer printing technology came into being. It makes dyes from color inks with sublimation properties, first prints them on transfer printing paper, and then under room temperature and pressure, makes the transfer printing paper and fabric fit together fully, so that the dye diffuses into the fabric to complete the coloring. Compared with heat transfer printing, cold transfer printing has significant advantages in printing natural fiber fabrics such as cotton, wool, and silk. For example, a printing method is used to print suitable dye inks on special paper to form transfer printing paper. The fabric after alkali rolling and the transfer printing paper enter the transfer roller at the same time. Pressure is used to separate the dye ink from the paper and transfer it to the fabric. Patent: CN213834844U discloses a cold transfer printing device with wastewater recycling, comprising a first purification box, a box cover fixedly connected to the top outer wall of the first purification box, a water inlet pipe fixedly connected to the top outer wall of the box cover, a first impurity collection device fixedly connected to both inner walls of the first purification box, a first filter screen and a second filter screen movably connected to the outer walls of the first impurity collection device, a second impurity collection device fixedly connected to both outer walls of the first purification box, and a first movable rod fixedly connected to one outer wall of the first impurity collection device. A spring rebound causes a cleaning ball to shake off impurities on the first and second filters to prevent impurities from clogging the meshes. The device facilitates multiple filtration of sewage through the provision of the first and second filters, resulting in a better purification effect. It also facilitates the collection of impurities in the sewage, preventing clogging of the filters. In the above technology, multi-layer filter screens are set up for filtration to remove impurities in sewage. The filter screens are prone to clogging in long-term practical use, which affects the filtration efficiency. In addition, the impurities in the printing wastewater are mostly fiber debris and fluff, which are mostly suspended matter and easily adhere to the filter screen, making it inconvenient to clean the filter screen. Therefore, it is not convenient to filter and remove fiber debris and fluff. In addition, when the purification liquid is added for purification in the above technology, it is only stirred in one direction by a single stirring device, and the mixing effect is poor. In addition, when it comes to powdered purification agents, it is impossible to ensure that the agents are fully mixed, and improvement is needed. For this reason, we propose a cold transfer printing equipment with wastewater recycling treatment. Summary of the Invention

[0013] Beneficial Effects: Through the synergistic effect of the salvage mechanism and the mixed purification mechanism, cold transfer printing wastewater can be recycled after impurities are salvaged and purified with chemicals, significantly reducing fresh water consumption. The collection box centrally stores fiber impurities for subsequent processing or recycling, reducing solid waste pollution. The purification box effectively removes alkaline substances, residual dyes, and additives from the wastewater through chemical reactions, reducing the risk of water pollution caused by wastewater discharge. The salvaging mechanism actively removes suspended impurities such as fiber debris and fluff, which has significant advantages over traditional filter interception methods. The static box provides a static space for wastewater, allowing impurities to float naturally. The motor drives the reciprocating screw to move the screw sleeve, mounting base and fan horizontally. The fan generates a directional airflow to gather impurities to the rear of the static box, solving the problem of scattered impurities that are difficult to remove. When the screw sleeve moves to the right and squeezes the pressure plate, the guide column, movable plate, toggle plate and toggle head are driven to rotate in conjunction with the spiral toggle groove, and then the transmission belt and transmission wheel one drive the shaft and the salvage plate to flip, which can accurately salvage the concentrated impurities and shake them into the collection box. The elastic reset effect of the spring ensures that the salvage plate automatically resets after salvaging, forming a continuous operation cycle. This structure avoids the problem of clogging caused by fiber impurities adhering to the filter screen, reduces the frequency of equipment shutdown for cleaning, and improves the efficiency of impurity removal. The mixing and purification mechanism achieves full mixing of the reagent and wastewater through a composite transmission structure. Motor 2 drives the stirring rod, rotating seat and annular frame to rotate, driving the rotating rod to revolve around the stirring rod. Gear 1 on the rotating rod engages with the arc-shaped inner tooth plate to achieve self-rotation. At the same time, Gear 2 drives Gear 4 through Gear 3 and the shaft column to alternately engage with the arc-shaped outer tooth plate, so that the rotating rod completes alternating forward and reverse rotation during the revolution. This composite motion drives the stirring blade to generate multi-directional water flow disturbance. Compared with single-direction stirring, it greatly improves the dispersion uniformity of the powdered purification reagent and ensures that the reagent fully reacts with alkaline substances, residual dyes and other pollutants in the wastewater. In the salvage mechanism, the reciprocating screw simultaneously drives the fan to translate and the salvage plate to flip, and the power is transmitted through the contact between the screw sleeve and the pressure plate. No additional driving device is required, which simplifies the structure and reduces energy consumption. In the mixing and purification mechanism, the rotational motion of the stirring rod is converted into the compound motion of the rotating rod through the engagement of the gear and the tooth plate. The transmission path is clear and efficient, and the cooperation between the limit slider and the circular groove ensures that the moving parts are not offset. BRIEF DESCRIPTION OF THE DRAWINGS

The input end of the extraction pump 121 is connected to the interior of the static box 101. A collection box 123 is fixedly connected to the rear surface of the static box 101; The wastewater generated by cold transfer printing first enters the still box 101. The side panels 102 on both sides of the top of the still box 101 provide installation support for the entire mechanism. During the still process, suspended impurities such as fiber debris and fluff gradually float up or suspend on the surface of the water body, and the motor 103 located in front of the left side panel 102 on the upper surface of the still box 101 is started. The right end of its output shaft drives the reciprocating screw 104 between the two side panels 102 to rotate, and the screw sleeve 105 threadedly connected to the outer wall of the reciprocating screw 104 makes a left and right reciprocating motion along the reciprocating screw 104 through threaded cooperation. The mounting seat 106 fixed on the rear surface of the screw sleeve 105 moves synchronously with the screw sleeve 105, and the fan 107 on the side of the mounting seat 106 away from the screw sleeve 105 moves horizontally accordingly.

When the screw sleeve 105 approaches the right side of the inside of the static tank 101, it will contact and extrude the pressure plate 115 sleeved on the right side wall of the reciprocating screw rod 104, and move the pressure plate 115 to the right. A plurality of guide columns 116 fixed on the right side of the pressure plate 115 move to the right, and the guide columns 116 at the right end penetrate through the side plate 102 on the right side of the upper surface of the static tank 101, and jointly push the movable plate 117 to move to the right.
