Description

Technical Field

[0001] The present invention relates to the technical field of printing and dyeing wastewater treatment equipment, and more specifically, to a printing and dyeing wastewater treatment equipment and a use method thereof. Background Art

[0002] The printing and dyeing industry is a typical high-water-consuming industry, which consumes nearly 100 million tons of softened water for process use every year. The sources and pollutant composition of printing and dyeing wastewater are very complex, with characteristics such as large changes in water quality, high organic matter content, and high chroma (mainly colored dyes). Direct discharge poses great harm to human health and the living environment, and also causes waste of water resources.

[0003] When the existing waste liquid cleaning device is in use, the liquid storage box is usually placed at the drain outlet, and then the valve is started to transport the waste liquid collected in the liquid storage box to the cleaning box through the connecting pipe. The cleaning agent in the cleaning box comes into contact with the waste liquid to purify the harmful substances or pollutants contained in the waste liquid, and finally it is discharged through the discharge pipe, thereby completing the waste liquid cleaning work.

[0004] In actual use of the prior art, since the waste liquid contains particulate matter, direct contact with the cleaning agent and disinfectant can easily lead to uneven mixing, affecting the subsequent cleaning effect of the waste liquid. Therefore, in view of the above technical problems, it is necessary to provide a printing and dyeing wastewater treatment equipment and its use method. Summary of the invention

[0005] The object of the present invention is to provide a printing and dyeing wastewater treatment device and a method of using the same to solve the above-mentioned problems.

[0006] In order to achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows:

[0007] A printing and dyeing wastewater treatment device comprises a cleaning box, a filter, a mixing element and an adjusting element, wherein a plurality of supporting rods are fixedly connected to the bottom of the cleaning box, a connecting pipe is connected to the interior of the cleaning box, and a liquid storage box is fixedly connected to one end of the connecting pipe; the filter is arranged in the interior of the cleaning box, the filter comprises an arc-shaped filter screen arranged in the interior of the cleaning box, and a plurality of metal spring sheets are fixedly connected to the outer surface of the arc-shaped filter screen; the mixing element is arranged in the interior of the cleaning box, the mixing element comprises a rotating rod rotatably connected to the interior of the cleaning box, a rotating ball is fixedly connected to the outer surface of the rotating rod, and a plurality of impellers are fixedly connected to the outer surface of the rotating rod close to the upper surface of the rotating ball.

[0008] The adjusting part is arranged on the outer surface of the rotating rod, and the adjusting part includes a cleaning channel fixedly connected to the inside of the cleaning box. The outer surface of the rotating rod is fixedly connected to a plurality of elastic pads, the outer surface of the elastic pad is fixedly connected to the adjusting rod, the outer surface of the adjusting rod is fixedly connected to a water retaining cloth, the inner cavity of the adjusting rod is fixedly connected to a magnet, the inner cavity of the rotating ball is fixedly connected to an electromagnet, and the magnet is magnetically connected to the electromagnet.

[0009] As a further improvement of the present invention, a rubber pad is fixedly connected to the inside of the liquid storage box, and a negative pressure generator is provided on the outer surface of the connecting tube. The rubber pad can effectively seal the bottom of the liquid storage box to prevent leakage of waste liquid. When the negative pressure generator pumps the waste liquid in the liquid storage box into the cleaning box through the connecting tube, this negative pressure suction method can ensure that the waste liquid is smoothly transported from the liquid storage box to the cleaning box, avoiding the inconvenience of manual dumping and potential pollution risks.

[0010] As a further improvement of the present invention, the cleaning channel is in a cross-sectional shape, a discharge pipe is provided between the cleaning channel and the interior of the cleaning box, a quantitative valve is provided on the outer surface of the discharge pipe, and the cleaning channel is in a cross-sectional shape so that the waste liquid can flow smoothly. At the same time, the cleaning channel guides the filtered waste liquid to flow downward, ensuring that the waste liquid can be discharged from the cleaning box through the discharge pipe.

[0011] As a further improvement of the present invention, a constant temperature chamber is provided inside the cleaning box through a partition, the constant temperature chamber is filled with coolant, a plurality of heating pipes are fixedly connected inside the constant temperature chamber, a temperature sensor is fixedly connected inside the constant temperature chamber, the heating pipe heats the coolant to increase the temperature of the coolant, and then transfers heat to the waste liquid in the cleaning box, and the temperature sensor monitors the temperature in the constant temperature chamber in real time to ensure that the temperature is controlled within a set range, usually 40-50°C. This helps to improve the mixing effect of the cleaning agent and the waste liquid, promote the disinfection and neutralization reactions, accelerate the chemical reaction between the cleaning agent and the waste liquid through the appropriate temperature, and improve the disinfection and neutralization effects.

[0012] As a further improvement of the present invention, a spraying part is provided inside the cleaning box, and the spraying part includes two spraying pipes symmetrically connected inside the cleaning box. A plurality of atomizing spray guns are provided on the outer surfaces of the two spraying pipes. The cleaning agent or disinfectant can be evenly sprayed into the cleaning box through the plurality of atomizing spray guns to ensure that the cleaning agent is in full contact with the waste liquid. At the same time, the atomizing spray gun atomizes the cleaning agent or disinfectant into fine particles, thereby increasing the contact area between the cleaning agent and the waste liquid and improving the mixing effect.

[0013] As a further improvement of the present invention, two waste pipes are arranged inside the cleaning box near the arc-shaped filter screen, and the filtered solid particles and large impurities are discharged through the waste pipes to keep the inside of the cleaning box clean. At the same time, the waste pipes can prevent solid particles from clogging other pipes inside the cleaning box, ensuring smooth waste liquid treatment.

[0014] As a further improvement of the present invention, the elastic pad is made of an elastic repositionable material, such as silicone or TPU. The elastic pad can be expanded or contracted by the adjusting rod to adjust the gap size of the cleaning channel. The elastic characteristics of the elastic pad can ensure that it remains sealed during the expansion or contraction process to prevent leakage of waste liquid.

[0015] As a further improvement of the present invention, a connecting block is fixedly connected to the side of the negative pressure generator, and the connecting block is fixedly connected to the outer surface of the cleaning box to ensure the stability and firmness of the negative pressure generator.

[0016] As a further improvement of the present invention, the water retaining cloth is made of high-strength flexible material. When unfolded, the water retaining cloth can cover the surface of the waste liquid to prevent the waste liquid from splashing and keep the wastewater treatment environment clean. Driven by the adjusting rod, the water retaining cloth can be expanded or contracted to adjust the flow speed of the waste liquid in the cleaning box.

[0017] As a further improvement of the present invention, the two spray pipes are inserted into the outer surface of the cleaning box and are fixedly connected to a fixed pipe, and a valve is provided on the outer surface of the fixed pipe. The fixed pipe is used to connect the cleaning agent or disinfectant container to ensure that the cleaning agent or disinfectant can be smoothly transported to the spray pipe. The flow rate of the cleaning agent or disinfectant can be adjusted by the valve to ensure the stability and uniformity of the spraying process.

[0018] A method for using a printing and dyeing wastewater treatment device comprises the following steps:

[0019] S1. The operator first places the liquid storage box at the drain outlet, and ensures that it abuts against the wastewater outlet through the elasticity of the rubber pad in the liquid storage box, and then connects the fixed pipe to the cleaning agent or disinfectant container. Subsequently, the valve is activated to pump the cleaning agent or disinfectant into the fixed pipe, and then transported to the atomizing spray gun through the fixed pipe and the spray pipe, and then sprayed out through multiple atomizing spray guns;

[0020] S2, then start the heating tube inside the constant temperature chamber; then turn on the negative pressure generator, and the filtered waste liquid flows downward into the cleaning channel under gravity;

[0021] S3. If there is too much waste liquid to be cleaned, the electromagnet is started and energized; if there is too little waste liquid, the electromagnet is started to generate negative magnetic force, causing the magnet to drive the adjustment rod and the water retaining cloth to shrink inward, and at the same time drive the elastic pad to compress, so that the space in the cleaning channel allowing the waste liquid to flow is larger, thereby flexibly adjusting the gap size of the cleaning channel to adapt to different waste liquid flow rates.

[0022] Compared with the prior art, the advantages of the present invention are:

[0023] (1) This solution places the liquid storage box at the drain outlet and ensures that the liquid storage box is in contact with the water outlet through the elasticity of the rubber pad on the surface of the liquid storage box. The disinfectant or cleaning agent is pumped into the spray gun pipe through the fixed pipe by starting the valve, and finally sprayed through the atomizing spray gun.

[0024] (2) Start the heating tube to heat the coolant in the constant temperature chamber, thereby heating the waste liquid in the cleaning box by transferring heat. At the same time, the temperature sensor monitors its temperature in real time to ensure that the temperature is controlled within the set range, usually 40-50°C, to avoid excessively high or low temperatures affecting the treatment effect, thereby ensuring that the cleaning agent and waste liquid react at a suitable temperature, ensuring that the waste liquid reacts at a suitable temperature, and improving the disinfection and neutralization effects.

[0025] (3) When the waste liquid enters the cleaning box, the impact force drives the impeller to rotate, thereby prompting the rotating rod to rotate, so as to break up the waste liquid and make it drip down from both sides. The waste liquid can be initially filtered through the arc filter to remove solid particles and large impurities, thereby improving the purity of the waste liquid. At the same time, the impact force of the waste liquid causes the metal shrapnel to vibrate, thereby improving the filtering effect and preventing the filter from being blocked. It is also possible to avoid uneven mixing due to direct contact between the particles contained in the waste liquid and the cleaning agent and disinfectant, which affects the cleaning effect of the waste liquid in the later stage.

[0026] (4) The filtered waste enters the cleaning channel. When there is too much waste liquid, the electromagnet is started to generate positive magnetic force. The magnet generates positive magnetic force, which prompts the magnet to drive the water retaining cloth to expand through the adjustment rod. At the same time, the adjustment rod drives the elastic pad to expand outward, narrowing the gap in the cleaning channel and slowing down the flow of waste. On the contrary, if there is too little waste liquid, the electromagnet is started to generate negative magnetic force, prompting the magnet to drive the adjustment rod and the water retaining cloth to shrink inward, and at the same time drive the elastic pad to compress, so that the space in the cleaning channel allowing the waste liquid to flow is larger, so that it can be flexibly adjusted according to the waste liquid flow rate to adapt to different waste liquid treatment conditions.

[0027] (5) When the rotating rod rotates, the water retaining cloth and the adjusting rod will be driven to rotate so as to mix and stir the waste liquid and the disinfectant, thereby ensuring that the disinfectant is in full contact with the waste liquid for disinfection and neutralization. The waste liquid that has been disinfected and neutralized is discharged through the discharge pipe inside the cleaning box, ensuring that the harmful substances and pollutants in the waste liquid have been effectively purified. At the same time, the sealing of the water retaining cloth and the elastic pad can prevent leakage of the waste liquid, thereby ensuring the safety of the operating environment.

[0028] (6) The waste liquid that has been disinfected and neutralized is discharged through the discharge pipe, ensuring that the harmful substances and pollutants in the waste liquid have been effectively purified and reducing pollution to the environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0038] Embodiment 1:

[0039] See also Figure 1-Figure 6 , a printing and dyeing wastewater treatment equipment and a method of using the same, comprising a cleaning box 1, a plurality of support rods 101 are fixedly connected to the bottom of the cleaning box 1, a connecting pipe 102 is connected to the inside of the cleaning box 1, and one end of the connecting pipe 102 is fixedly connected to a liquid storage box 103; a filter element 2 is arranged inside the cleaning box 1, and the filter element 2 comprises an arc-shaped filter screen 201 arranged inside the cleaning box 1, and a plurality of metal springs 202 are fixedly connected to the outer surface of the arc-shaped filter screen 201, and the metal spring 202 is an elastic element made of metal material, usually having a thin sheet or spring-shaped structure, and the metal spring 202 will deform when subjected to external force, and can return to its original shape when the external force disappears, and when the metal spring 202 is impacted by the waste liquid, it will drive the arc-shaped filter screen 201 to vibrate, thereby improving the filtering effect.

[0040] The mixing element 3 is arranged inside the cleaning box 1, and the mixing element 3 includes a rotating rod 301 rotatably connected inside the cleaning box 1, a rotating ball 302 is fixedly connected to the outer surface of the rotating rod 301, and a plurality of impellers 303 are fixedly connected to the outer surface of the rotating rod 301 near the upper surface of the rotating ball 302.

[0041] Specifically, the inside of the liquid storage box 103 is fixedly connected with a rubber pad 104. The rubber pad 104 is a pad made of rubber material, which is usually used for sealing, cushioning and leak-proofing. The rubber pad 104 can ensure that the waste liquid can be completely collected in the liquid storage box 103, avoiding the risk of contaminating the ground. At the same time, the surface of the rubber pad 104 is smooth and easy to clean and disinfect, ensuring that it remains clean after multiple uses.

[0042] A negative pressure generator 105 is provided on the outer surface of the connecting pipe 102. The negative pressure generator 105 is a device that can generate negative pressure (pressure lower than atmospheric pressure). It creates a low-pressure area by inhaling air or other gases, so that liquid or gas can be extracted. The negative pressure generator 105 can accurately control the negative pressure value to prevent waste liquid from overflowing during the extraction process, thereby ensuring the cleanliness and safety of the wastewater treatment environment. At the same time, the negative pressure generator 105 can quickly extract waste liquid, shorten the time of waste liquid treatment, and improve efficiency.

[0043] A connection block is fixedly connected to the side of the negative pressure generator 105, and the connection block is fixedly connected to the outer surface of the cleaning box 1. Two spray pipes 601 are inserted into the outer surface of the cleaning box 1 and fixedly connected to a fixed pipe 603. A valve is provided on the outer surface of the fixed pipe 603. The valve is a mechanical device for controlling the flow of fluid (liquid, gas or steam). It adjusts the flow, pressure or direction of the fluid by opening, closing or partially opening, thereby ensuring that the disinfectant or cleaning agent enters the fixed pipe 603 and controls its flow.

[0044] Further, the liquid storage box 103 is placed at the drain outlet, and the fixed pipe 603 is connected to the cleaning agent or disinfectant container through the elasticity of the rubber pad 104 in the liquid storage box 103. Then, the valve is started to pump the cleaning agent or disinfectant into the fixed pipe 603, and then the cleaning agent or disinfectant is transported to the atomizing spray gun 602 through the fixed pipe 603 and the spraying pipe 601, and then the atomizing spray gun 602 is sprayed out through multiple atomizing spray guns 602. The heating pipe 502 in the constant temperature chamber 501 is started to heat the cooling liquid in the constant temperature chamber 501, so that the waste liquid in the cleaning box 1 is heated by the transfer heating, and the negative pressure generator 105 is turned on to heat the waste liquid in the liquid storage box 103 through the connecting pipe 102. The liquid is pumped into the cleaning box 1. When the waste liquid enters the cleaning box 1, the airflow generated will drive the impeller 303 to rotate. When the impeller 303 rotates, it will drive the rotating rod 301 to rotate. When the rotating rod 301 rotates, it will drive the rotating ball 302 to rotate, so that the rotating ball 302 will break up the cleaning agent or disinfectant sprayed into the cleaning box 1, and at the same time, it will break up the waste liquid entering the cleaning box 1, so that the waste liquid drips down from both sides, and the solid particles and large impurities in the waste liquid can be filtered through the arc filter 201. At the same time, the multiple metal springs 202 on the surface of the arc filter 201 are impacted by the waste liquid, thereby driving the arc filter 201 to vibrate, thereby improving its filtering effect.

[0045] Embodiment 2:

[0046] Reference Figure 1-Figure 6 , which is a new second embodiment of the present invention, is based on the previous embodiment, and the mixing element 3 includes a rotating rod 301 rotatably connected to the inside of the cleaning box 1.

[0047] Specifically, the adjusting member 4 is arranged on the outer surface of the rotating rod 301, and the adjusting member 4 includes a cleaning channel 401 fixedly connected to the inside of the cleaning box 1, the outer surface of the rotating rod 301 is fixedly connected to multiple elastic pads 402, the outer surface of the elastic pad 402 is fixedly connected to the adjusting rod 403, the outer surface of the adjusting rod 403 is fixedly connected to the water retaining cloth 404, the inner cavity of the adjusting rod 403 is fixedly connected to the magnet 405, the inner cavity of the rotating ball 302 is fixedly connected to the electromagnet 406, and the magnet 405 is magnetically connected to the electromagnet 406.

[0048] The cleaning channel 401 is in a cross-sectional shape, and a discharge pipe is arranged inside the cleaning channel 401 and the cleaning box 1. A quantitative valve is arranged on the outer surface of the discharge pipe. The quantitative valve is a valve that can accurately control the flow rate of fluid (liquid or gas). It ensures that the output volume of the fluid remains consistent each time it is used by setting a specific opening or flow value. The quantitative valve on the discharge pipe can accurately control the discharge volume of the treated waste liquid to ensure efficient and safe waste liquid treatment.

[0049] The elastic pad 402 is made of an elastic repositionable material. The elastic properties of the elastic pad 402 make the adjustment process smoother and avoid the instability caused by sudden changes. At the same time, the elastic pad 402 has good sealing performance and can maintain sealing even during the expansion or contraction process to prevent waste liquid from leaking from the edge of the cleaning channel 401, thereby ensuring the efficiency and safety of waste liquid treatment. The elastic pad 402 can be reset and can still maintain a good sealing effect even after multiple uses, thereby extending the service life of the equipment. The elastic properties of the elastic pad 402 enable it to adapt to different waste liquid flows and working conditions. Whether there is too much or too little waste liquid, the treatment effect can be optimized by adjusting the gap size of the cleaning channel 401.

[0050] The water retaining cloth 404 is made of high-strength flexible material, which can be replaced by polyester fiber, nylon, PVC (polyvinyl chloride), polyester fiber, polypropylene and other materials. The water retaining cloth 404 can prevent the penetration of waste liquid, ensure that the waste liquid will not seep out of the water retaining cloth 404, keep the wastewater treatment environment clean and safe, and has high strength and toughness, can resist the erosion of particulate matter and chemicals in the waste liquid, extend the service life of the water retaining cloth 404, so that the water retaining cloth 404 is more flexible during the expansion and contraction process, reduce operating resistance, and improve the response speed of the equipment. Two waste pipes 7 are arranged inside the cleaning box 1 near the arc filter 201.

[0051] Furthermore, the filtered waste liquid flows downward into the cleaning channel 401 due to gravity. If the cleaned waste liquid is too much, the electromagnet 406 is started and energized to generate positive magnetic force, and the magnet 405 generates positive magnetic force, prompting the magnet 405 to drive the water retaining cloth 404 to expand through the adjusting rod 402, thereby reducing the gap in the cleaning channel 401 and slowing down the flow of waste materials. On the contrary, if the waste liquid is too little, the electromagnet 406 is started to generate negative magnetic force, prompting the magnet 405 to drive the adjusting rod 402 and the water retaining cloth 404 to shrink inward, so that the space for the waste liquid to flow in the cleaning channel 401 is larger, thereby avoiding the direct contact of particles contained in the waste liquid with the cleaning agent and the disinfectant, which may cause uneven mixing and affect the cleaning effect of the waste liquid in the later stage. At the same time, when the rotating rod 301 rotates, the water retaining cloth 404 and the adjusting rod 402 will be driven to rotate, so as to mix and stir the waste liquid and the disinfectant, thereby ensuring that the disinfectant is in full contact with the waste liquid for disinfection and neutralization.

[0052] The working principle of the present invention is as follows: firstly, the liquid storage box 103 is placed at the drain outlet, and the elasticity of the rubber pad 104 in the liquid storage box 103 is used to ensure that it is in contact with the water outlet, and then the fixed pipe 603 is connected to the cleaning agent or disinfectant container, and then, the valve is started to allow the cleaning agent or disinfectant to be pumped into the fixed pipe 603, and transported to the atomizing spray gun 602 through the fixed pipe 603 and the spraying pipe 601, and sprayed out through multiple atomizing spray guns 602, and the heating pipe 502 inside the constant temperature chamber 501 is started to heat the coolant in the constant temperature chamber 501 by the heating pipe 502, so as to heat the waste liquid in the cleaning box 1 by transfer heating, and at the same time, the temperature sensor 503 monitors its temperature in real time to ensure that the temperature is controlled within the set range, usually 40-50°C, so as to ensure that the cleaning agent and the waste liquid react at an appropriate temperature.

[0053] Subsequently, the negative pressure generator 105 is turned on, and the waste liquid in the liquid storage box 103 is pumped into the cleaning box 1 through the connecting pipe 102. When the waste liquid enters the cleaning box 1, the airflow generated will drive the impeller 303 to rotate. When the impeller 303 rotates, it will drive the rotating rod 301 to rotate. When the rotating rod 301 rotates, it will drive the rotating ball 302 to rotate, so that the rotating ball 302 will break up the cleaning agent or disinfectant sprayed into the cleaning box 1, and at the same time, it will break up the waste liquid entering the cleaning box 1, so that the waste liquid drips down from both sides, and the solid particles and large impurities in the waste liquid can be filtered through the arc filter 201. At the same time, the multiple metal springs 202 on the surface of the arc filter 201 are impacted by the waste liquid, thereby driving the arc filter 201 to vibrate, thereby improving its filtering effect.

[0054] The filtered waste liquid flows downward into the cleaning channel 401 under the force of gravity. If the cleaned waste liquid is too much, the electromagnet 406 is started and energized to generate a positive magnetic force, and the magnet 405 generates a positive magnetic force, prompting the magnet 405 to drive the water retaining cloth 404 to expand through the adjusting rod 402, and at the same time, the adjusting rod 402 drives the elastic pad 402 to expand outward, thereby reducing the gap in the cleaning channel 401 and making the waste flow slower. On the contrary, if the waste liquid is too little, the electromagnet 406 is started to generate a negative magnetic force, prompting the magnet 405 to drive the adjusting rod 402 and the water retaining cloth 404 to shrink inward, and at the same time drive the elastic pad 402 to compress, so that the cleaning channel 401 is not full. 01 allows a large space for waste liquid to circulate, so that the gap size of the cleaning channel 401 can be flexibly adjusted to adapt to different waste liquid flow rates, avoiding uneven mixing caused by direct contact of particles in the waste liquid with the cleaning agent and disinfectant, which affects the cleaning effect of the waste liquid in the later stage. At the same time, when the rotating rod 301 rotates, it will drive the water retaining cloth 404 and the adjusting rod 402 to rotate, so as to mix and stir the waste liquid and the disinfectant, thereby ensuring that the disinfectant is in full contact with the waste liquid for disinfection and neutralization treatment. The waste liquid that has been disinfected and neutralized is discharged through the discharge pipe inside the cleaning box 1, ensuring that the harmful substances and pollutants in the waste liquid have been effectively purified.

A printing and dyeing wastewater treatment equipment according to claim 5, characterized in that: The two spray pipes (601) are inserted into the outer surface of the cleaning box (1) and are fixedly connected to a fixed pipe (603), and a valve is provided on the outer surface of the fixed pipe (603).

10. A method for using a printing and dyeing wastewater treatment device, characterized in that: The following steps are involved: S1. The operator first places the liquid storage box (102) at the drain outlet, and ensures that the rubber pad (103) in the liquid storage box (102) is in contact with the wastewater outlet through the elasticity of the rubber pad (103), and then connects the fixed pipe (603) to the cleaning agent or disinfectant container. Subsequently, the valve is activated to pump the cleaning agent or disinfectant into the fixed pipe (603), and then the cleaning agent or disinfectant is transported to the atomizing spray gun (602) through the fixed pipe (603) and the spraying pipe (601), and then sprayed out through multiple atomizing spray guns (602); S2, then start the heating tube (502) inside the constant temperature chamber (501); then turn on the negative pressure generator (105), and the filtered waste liquid flows downward into the cleaning channel (401) under the force of gravity; S3. If the waste liquid to be cleaned is too much, the electromagnet (406) is started and energized; if the waste liquid is too little, the electromagnet (406) is started to generate a negative magnetic force, which causes the magnet (405) to drive the adjustment rod (403) and the water retaining cloth (404) to shrink inward, and at the same time drives the elastic pad (402) to be compressed, so that the space in the cleaning channel (401) allowing the waste liquid to flow is larger, thereby flexibly adjusting the gap size of the cleaning channel (401) to adapt to different waste liquid flow rates.
