Description

Technical Field

[0001] This utility model relates to the field of water circulation equipment technology, and in particular to a water transfer printing water circulation device. Background Technology

[0002] In traditional water transfer printing, the printing substrate (such as wine bottle label film) needs to be printed with patterns through water pressure in a water tank. This process generates a large amount of wastewater containing ink, dissolved adhesives and impurities. Direct discharge can easily cause pollution, while frequent water changes increase costs.

[0003] In the prior art, a search revealed a Chinese patent disclosing "A Water Transfer Printing Water Circulation Device," application number "201921351542.8." This patent mainly includes a water circulation device. A partition is fixedly connected inside the water circulation device, dividing it into a heating tank and a water transfer printing tank. A filter screen is detachably connected inside the heating tank. A first cavity is provided at the bottom of the water circulation device, and a circulation pump is fixedly connected to the bottom of the first cavity. The input end of the circulation pump is connected to the heating tank, and the output end of the circulation pump is fixedly connected to a connecting pipe. A second cavity is provided on the right side wall of the water circulation device. This utility model, by setting up a circulation pump, can recycle water, saving water resources. Combined with a water guiding mechanism, it can help water and scum enter the heating tank from the water transfer printing tank. With the filter screen, it can effectively filter scum, preventing scum from entering the circulation pump. This patent not only saves water resources but also reduces the time spent on frequent water changes, accelerating the work progress. However, simple filtration with a filter screen can only intercept larger particles, while wastewater contains ink, dissolved colloids, and other impurities. The water quality after simple filtration is difficult to meet reuse standards. Therefore, this invention provides a water transfer printing water recycling device to solve the problems mentioned in the background section. Utility Model Content

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4 This utility model provides a water transfer printing water circulation device, which includes a housing 1. A first partition 2 and a second partition 3 are fixed on the bottom wall of the housing 1. The first partition 2 is L-shaped. A filter screen 4 is provided above the first partition 2. A pH sensor 9 is fixed on the inner wall of the housing 1 and located between the first partition 2 and the second partition 3. A feed pipe 10 is fixed on the top of the housing 1 and located above the pH sensor 9. The feed pipe 10 is used to deliver an acid-base regulator between the first partition 2 and the second partition 3.

[0024] The tank 1, through the first partition 2 and the second partition 3, forms a pretreatment zone on the left, a chemical treatment zone in the middle, and a deep purification zone on the right. The filter screen 4 in the pretreatment zone intercepts solid impurities (such as label residue and particulate matter). The pre-filtered water flows along the guide at the top of the first partition 2 into the middle chemical treatment zone between the first partition 2 and the second partition 3. The pH sensor 9 in the chemical treatment zone monitors the water's acidity and alkalinity in real time. When an abnormal pH value is detected, an acid-base adjuster can be added through the feed pipe 10 to neutralize the pH and ensure a uniform and stable pH value. Simultaneously, the chemical treatment zone also serves as a flocculation reaction tank, where PAC (polyaluminum chloride) and PAM (polyacrylamide) are added and mixed with the wastewater to promote the flocculation of small particles.

[0025] Inside the tank 1, between the second partition 3 and the side wall of the tank 1, there is an activated carbon layer 5 and a ceramic membrane layer 6 arranged vertically. A heater 15 is fixed on one side of the side wall of the tank 1 and one side of the second partition 3. A UV sterilizing lamp 14 is fixed on the inner wall of the tank 1, below the ceramic membrane layer 6 and on one side of the second partition 3. A temperature sensor 16 is fixed on the inner wall of the tank 1, below the UV sterilizing lamp 14, for monitoring the water temperature.

[0026] The right side of the chamber 1 is the deep purification zone. The water pump 17 delivers the neutralized water to the deep purification zone, where it flows sequentially through the activated carbon layer 5 (adsorbing organic pollutants) and the ceramic membrane layer 6 (precision filtration) to achieve precision filtration. After the UV germicidal lamp 14 kills microorganisms in the water, the water is heated to the temperature required for transfer printing by the heater 15 and the temperature sensor 16. The water then flows back to the water transfer tank for reuse through the drain pipe 18.

[0027] An overflow plate 7 is fixed on the inner wall of the box 1 above the filter screen 4 and the activated carbon layer 5. An inlet pipe 8 extending to the overflow plate 7 is fixed on the top of the box 1. A water pump 17 is fixed on the top of the second partition 3. A pipe extending between the first partition 2 and the second partition 3 is fixed at the inlet end of the water pump 17. A water delivery pipe 19 extending to the overflow plate 7 is fixed at the outlet end of the water pump 17.

[0028] The transfer wastewater containing ink and adhesive enters the tank 1 through the inlet pipe 8, flows evenly to the filter screen 4 after being evenly distributed by the overflow plate 7, and the water pump 17 draws water from inside the chemical treatment area and evenly distributes it to the activated carbon layer 5 through the water supply pipe 19 and the overflow plate 7.

[0029] A stirrer 13 is also provided between the first partition 2 and the second partition 3. A guide plate 11 is fixed at the bottom of the box body 1 and below the stirrer 13. A drain pipe 12 is fixed at the bottom of the guide plate 11. A drain pipe 18 is fixed inside the box body 1 and below the ceramic membrane layer 6. Valves are provided on the outside of the drain pipe 12 and the drain pipe 18 to control the opening and closing of the drain pipe 12 and the drain pipe 18.

[0030] When agitator 13 is activated, it promotes uniform mixing of the acid-base regulator and wastewater. Flocculant is added to the chemical treatment area, and agitator 13 accelerates the flocculation reaction. The precipitated sludge is deposited on the feed tray 11 and periodically discharged through the drain pipe 12.

[0031] The bottom of the filter screen 4, activated carbon layer 5 and ceramic membrane layer 6 are all provided with support plates 20 fixed to the inner wall of the box 1. A slot 21 is opened inside the box 1 and on one side of the support plate 20. Insert plates 22 are inserted into the slots 21. The filter screen 4, activated carbon layer 5 and ceramic membrane layer 6 are all fixedly connected to the adjacent insert plates 22. The interference fit between the insert plates 22 and the slots 21 helps to maintain stability.

[0032] When the filter screen 4, activated carbon layer 5, or ceramic membrane layer 6 needs to be replaced, the corresponding component can be removed from the slot 21 by pulling out the insert plate 22, which is convenient to operate.

[0033] Working principle: Transfer wastewater containing ink and adhesive enters the tank 1 through the inlet pipe 8, and flows to the filter screen 4 after being evenly distributed by the overflow plate 7. The filter screen 4 intercepts solid impurities (such as label residue and particulate matter). The water after preliminary filtration flows into the middle chemical treatment area between the first partition 2 and the second partition 3 along the guide at the top of the first partition 2.

[0034] The pH sensor 9 in the chemical treatment area monitors the acidity and alkalinity of the water in real time. When an abnormal pH value is detected, an acid-base regulator can be added through the feed pipe 10 to neutralize the pH and ensure a uniform and stable pH value. At the same time, the chemical treatment area also serves as a flocculation reaction tank, where PAC (polyaluminum chloride) and PAM (polyacrylamide) are added and mixed with the wastewater to promote the flocculation of small particles.

[0035] The water pump 17 delivers the neutralized water to the deep purification area, where it flows sequentially through the activated carbon layer 5 (adsorbing organic pollutants) and the ceramic membrane layer 6 (precision filtration) to achieve precision filtration. After the UV germicidal lamp 14 kills microorganisms in the water, the water is heated to the temperature required for transfer printing by the heater 15 and the temperature sensor 16. The water is then returned to the water transfer tank for reuse through the drain pipe 18.

[0036] This water transfer printing water circulation equipment achieves efficient and stable water treatment through multi-stage synergistic purification. After the filter screen 4 completes the initial impurity interception, the pH sensor 9 and the feed pipe 10 work together to regulate the acidity and alkalinity of the water, and the flocculation process improves the sedimentation efficiency. The two-stage deep filtration system composed of activated carbon layer 5 and ceramic membrane layer 6 can effectively remove solid impurities, organic pollutants and tiny particles from the water. The UV germicidal lamp 14 and constant temperature heating system maintain water quality and temperature stability, improve the wastewater recycling rate and usage quality, and have both environmental benefits and economic benefits.

[0037] Unless otherwise specified, the pH sensor, feed pipe, stirrer, UV germicidal lamp, heater, temperature sensor, and water pump (components / elements of this utility model) described in this utility model are obtained from conventional commercial channels or manufactured by conventional methods. Their specific structures, working principles, and possible control methods and spatial arrangements can adopt conventional choices in the field and should not be regarded as the innovation of this utility model. This is understandable to those skilled in the art, and this utility model patent will not be further elaborated in detail.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
