Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment technology, and in particular to a treatment device for dyeing and printing wastewater. Background Technology

[0002] Textile dyeing and printing wastewater is characterized by large volume, high organic pollutant content, high alkalinity, and large fluctuations in water quality, making it one of the most difficult types of industrial wastewater to treat. The wastewater contains dyes, sizing agents, auxiliaries, oils, acids and alkalis, fiber impurities, sand, and inorganic salts. The main methods for treating dyeing and printing wastewater include physicochemical methods, biochemical methods, chemical methods, and combinations of several processes. Pretreatment in wastewater treatment primarily aims to improve wastewater quality, remove suspended solids and directly settleable impurities, regulate wastewater quality and quantity, and reduce wastewater temperature, thereby enhancing the overall treatment effect and ensuring the stability of the entire treatment system. Therefore, pretreatment plays an extremely important role in dyeing and printing wastewater treatment.

[0003] The patent titled "A Pretreatment Device for Dyeing and Printing Wastewater" (patent application number: 202222272525.3) discloses a pretreatment device for dyeing and printing wastewater, relating to the field of wastewater treatment technology. The device includes a pretreatment tank. A box is fixedly mounted on the upper part of the pretreatment tank via two fixed rods. A rotating shaft is rotatably connected inside the box. Rotating blades are fixed to the outer wall of the rotating shaft inside the box. One end of the rotating shaft extends to the outside of the box and is fixedly connected to a drive wheel. The drive wheel is connected to a driven wheel via a belt. The driven wheel is fixed to one end of the rotating shaft. The rotating shaft is rotatably connected to the top of two support plates. This device can separate and collect fiber impurities in the dyeing and printing wastewater, thereby reducing the amount of fiber impurities in the pretreatment tank and reducing sediment in the pretreatment tank. This facilitates subsequent cleaning of the pretreatment tank. It also allows for the intermittent addition of reagents based on the wastewater volume, avoiding the addition of excessive reagents at once and reducing waste.

[0004] In the above-mentioned case, when the reagents from the reagent hopper are added to the pretreatment tank, it is difficult to mix the reagents with the dyeing and printing wastewater. This easily leads to uneven mixing, resulting in slow sedimentation of impurities in the wastewater and hindering the automatic removal of these sediments. This causes inconvenience in the use of the device. Therefore, it is necessary to propose a wastewater treatment device for dyeing and printing wastewater to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a treatment device for dyeing and printing wastewater, so as to solve the problem mentioned in the background art that when the agent in the agent hopper is added to the pretreatment tank, it is not convenient to stir and mix the agent with the dyeing and printing wastewater, which easily leads to uneven mixing between the agent and the dyeing and printing wastewater. This results in a slow sedimentation rate of impurities in the dyeing and printing wastewater and makes it inconvenient to automatically clean the sedimented impurities in the dyeing and printing wastewater, which brings inconvenience to the use of the device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a treatment device for dyeing and printing wastewater, comprising a treatment tank, a movable component provided on the outer wall of the treatment tank, the movable component comprising a support plate, a lead screw rotatably connected inside the support plate, a forward and reverse motor fixedly connected to one end of the lead screw, and a thread block threadedly connected to the outside of the lead screw, the thread block having a thread hole that mates with the lead screw, and a support frame fixedly connected to the top of the thread block;

[0007] The bottom of the support frame is provided with a stirring assembly, which includes an electric push rod. The telescopic end of the electric push rod is fixedly connected to a fixed frame. A waterproof motor is fixedly connected to the outer side of the fixed frame. A rotating roller is fixedly connected to the outside of the output shaft of the waterproof motor. A rotating plate is fixedly connected to the outside of the rotating roller.

[0008] Preferably, the outside of the support plate is fixedly connected to the outer wall of the processing box, and the outside of the support plate is fixedly connected to the outside of the forward and reverse motors.

[0009] Preferably, a positioning rod is fixedly connected to the outside of the support plate, the outside of the positioning rod is slidably connected to the inside of the screw block, and the positioning rod and the screw are parallel to each other.

[0010] Preferably, the outer part of the waterproof motor output shaft is rotatably connected to the inner part of the fixed frame, and there are two rotating plates, which are symmetrically distributed on the outer part of the rotating roller shaft.

[0011] Preferably, a drain pipe is fixedly connected to the top of the outer side of the processing box, and a valve is fixedly installed on the outside of the drain pipe;

[0012] The bottom of the inner cavity of the processing box is provided with a sewage discharge trough, and a collection box is detachably connected to the inside of the sewage discharge trough.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] By coordinating the moving and stirring components, after the reagent is added to the treatment tank containing dyeing and printing wastewater, the waterproof motor is first turned on. The waterproof motor drives the rotating roller to rotate, which in turn drives the rotating plate to rotate. This causes the rotating plate to mix the dyeing and printing wastewater and reagent in the treatment tank. Simultaneously, the forward and reverse motors are turned on, which drive the stirring component to move within the treatment tank. This ensures that the rotating plate mixes the dyeing and printing wastewater and reagent throughout the tank, resulting in a uniform mixture and increasing the sedimentation rate of impurities in the wastewater. Once the impurities in the wastewater have settled, the waterproof motor adjusts the angle of the two rotating plates to be perpendicular to the treatment tank and then locks them in place. Next, the electric push rod is activated, causing the rotating plates to contact the bottom of the treatment tank's inner cavity. Finally, the forward and reverse motors drive the rotating plates to move horizontally, facilitating the automatic cleaning of the sedimented impurities at the bottom of the treatment tank. This greatly enhances the convenience of using the device. Attached Figure Description

[0019] 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.

[0020] This utility model provides, for example Figures 1-3The device for treating dyeing and printing wastewater includes a treatment tank 1. A movable assembly is installed on the outer wall of the treatment tank 1. The movable assembly includes a support plate 2. A lead screw 3 is rotatably connected inside the support plate 2. A forward / reverse motor 4 is fixedly connected to one end of the lead screw 3, and a threaded block 5 is threadedly connected to the outside of the lead screw 3. The threaded block 5 has a thread hole that mates with the lead screw 3, and a support frame 6 is fixedly connected to the top of the threaded block 5. The outside of the support plate 2 is fixedly connected to the outer wall of the treatment tank 1, and the outside of the support plate 2 is fixedly connected to the outside of the forward / reverse motor 4. A positioning rod 7 is fixedly connected to the outside of the support plate 2, and the outside of the positioning rod 7 is slidably connected to the inside of the threaded block 5. The positioning rod 7 is parallel to the lead screw 3 and limits the direction of movement of the threaded block 5. When the forward / reverse motor 4 is turned on, the lead screw 3 rotates, causing the threaded block 5 to move horizontally. The threaded block 5 then causes the support frame 6 to move horizontally, facilitating the subsequent mixing of dyeing and printing wastewater with chemicals and the cleaning of sediments from the wastewater.

[0021] In addition, a stirring assembly is provided at the bottom of the support frame 6. The stirring assembly includes an electric push rod 8, the telescopic end of which is fixedly connected to a fixed frame 9. A waterproof motor 10 is fixedly connected to the side of the fixed frame 9. A rotating roller shaft 11 is fixedly connected to the outside of the output shaft of the waterproof motor 10. A rotating plate 12 is fixedly connected to the outside of the rotating roller shaft 11. The outside of the output shaft of the waterproof motor 10 is rotatably connected to the inside of the fixed frame 9. There are two rotating plates 12, which are symmetrically distributed outside the rotating roller shaft 11. When the waterproof motor 10 is turned on, the waterproof motor 10 drives the rotating roller shaft 11 to rotate through the output shaft. The rotating roller shaft 11 drives the rotating plate 12 to rotate, so that the rotating plate 12 mixes and stirs the dyeing wastewater and chemicals in the treatment tank 1. At the same time, the forward and reverse motors 4 drive the stirring assembly to move in the treatment tank 1, so that the rotating plate 12 mixes and stirs the dyeing wastewater and chemicals in various parts of the treatment tank 1, making the chemicals and dyeing wastewater evenly mixed, thereby improving the sedimentation rate of impurities in the dyeing wastewater.

[0022] In this process, after impurities in the dyeing and printing wastewater settle, the waterproof motor 10 adjusts the angle of the two rotating plates 12 to be perpendicular to the treatment box 1, and then locks them. Next, the electric push rod 8 is opened, and the electric push rod 8 will drive the rotating plates 12 to move downward through the fixed frame 9, so that the rotating plates 12 contact the bottom of the inner cavity of the treatment box 1. Finally, the forward and reverse motors 4 drive the rotating plates 12 to move horizontally, which facilitates the automatic cleaning of the impurities settled at the bottom of the treatment box 1, bringing convenience to the use of the device.

[0023] Finally, a drain pipe 13 is fixedly connected to the top of the outer side of the treatment box 1, and a valve is fixedly installed on the outside of the drain pipe 13. A sewage discharge trough 15 is opened at the bottom of the inner cavity of the treatment box 1, and a collection box 14 is detachably connected inside the sewage discharge trough 15. When impurities in the dyeing and printing wastewater settle, the drain pipe 13 is first opened to discharge the wastewater inside the treatment box 1 to facilitate the next step of wastewater treatment. Then, the precipitate is scraped into the collection box 14 by the rotating plate 12. The staff can remove the precipitate collected inside the collection box 14 by disassembling it.

[0024] Working principle: When the reagent is added to the treatment tank 1 containing dyeing and printing wastewater, the waterproof motor 10 is turned on. The waterproof motor 10 drives the rotating roller 11 to rotate via the output shaft. The rotating roller 11 drives the rotating plate 12 to rotate, causing the rotating plate 12 to mix and stir the dyeing and printing wastewater and reagent in the treatment tank 1. At the same time, the forward and reverse motor 4 drives the stirring component to move in the treatment tank 1, causing the rotating plate 12 to mix and stir the dyeing and printing wastewater and reagent in all parts of the treatment tank 1. This ensures that the reagent and dyeing and printing wastewater are mixed evenly, thereby increasing the sedimentation rate of impurities in the dyeing and printing wastewater. After the impurities in the dyeing and printing wastewater have settled, The waterproof motor 10 adjusts the angle of the two rotating plates 12 to be perpendicular to the processing box 1, and then locks them. Next, the electric push rod 8 is opened, and the electric push rod 8 drives the rotating plates 12 to move downward through the fixing frame 9, so that the rotating plates 12 contact the bottom of the inner cavity of the processing box 1. Finally, the forward and reverse motors 4 drive the rotating plates 12 to move horizontally, which facilitates the automatic cleaning of the impurities settled at the bottom of the processing box 1. When the sediment is scraped into the collection box 14 by the rotating plates 12, the staff can disassemble the collection box 14 to easily remove the sediment collected inside the collection box 14, which brings convenience to the use of the device.
