Description

Technical Field

[0001] This application relates to the field of wastewater treatment technologies, and in particular, to a textile wastewater recycling device. Background Art

[0002] The textile industry is one of the important sources of wastewater discharge. During the production process, a large amount of wastewater containing harmful substances such as dyes and auxiliaries is generated. If directly discharged without treatment, it will cause serious pollution to the environment.

[0003] In related technologies, existing textile industry wastewater treatment devices generally use biochemical treatment technology in combination with physical and physicochemical methods to ensure the wastewater treatment effect. Before the textile industry wastewater undergoes coagulation and sedimentation treatment, it usually needs to be introduced into a regulating tank, where impurities and sediment in the wastewater are filtered through a grille plate, and the water quality and water volume are adjusted to reduce the subsequent treatment pressure.

[0004] Regarding the above related technologies, impurities and particulate matters in the wastewater easily cause the grille plate to become blocked and unable to continue working. However, existing grille plates are usually fixed on the inner side wall of the regulating tank, which requires frequent shutdown of the equipment and intervention by operators to dredge the grille plate, affecting the wastewater treatment efficiency. Summary of the Utility Model

[0005] In order to improve the problem of affecting the treatment efficiency of textile wastewater, this application provides a textile wastewater recycling device.

[0006] A textile wastewater recycling device provided by this application adopts the following technical solution:

The top of the treatment tank is open, and a placement groove is opened on the inner wall of the treatment tank near the open end.

[0008] The filtering component includes a mounting frame, a grille, and a cleaning member. The mounting frame is located at the placement groove. The outer side wall of the mounting frame fits with the groove wall of the placement groove. The mounting frame is connected to the treatment tank. The grille is connected inside the mounting frame. The grille is used to filter fibers and large impurities contained in the wastewater. The cleaning member includes a scraping plate, bristles, and a driving source. The scraping plate is slidably arranged on the side of the mounting frame away from the treatment tank. A plurality of the bristles are fixed on the side of the scraping plate close to the mounting frame. The bristles can clean the surface of the grille. The driving source is connected to the mounting frame and is connected to the scraping plate to drive the scraping plate to move. The recycling component includes a recycling tank for recycling wastewater. The bottom of the treatment tank is provided with a reduced opening, and the recycling tank is communicated with the bottom of the treatment tank.

[0009] By adopting the above technical solution, when it is necessary to recycle textile wastewater, first, the wastewater is introduced into the treatment tank. During the process of introducing the wastewater, the wastewater passes through the grille. The grille can filter the fibers and large impurities contained in the wastewater. The filtered wastewater flows into the treatment tank, where it can be treated. Subsequently, the treated wastewater flows into the recycling tank. When it is necessary to clean the grille, the driving source is activated. The driving source pushes the scraper to move along the surface of the installation frame. During the movement of the scraper, the bristles move synchronously with the scraper, and the bristles can clean the grille. Compared with the related technology, in this application, by setting the scraper and the bristles, when it is necessary to clean the grille, the driving source can push the scraper to clean the grille without stopping the operation of the equipment. During the operation of the equipment, the grille can be cleaned, which can improve the treatment efficiency of textile wastewater and is beneficial to solving the problems that affect the treatment efficiency of textile wastewater.

[0010] Optionally, the filtering assembly further includes a filtering element. The filtering element is located in the placement groove. The filtering element includes a first filter screen. The first filter screen is connected to the side of the installation frame close to the middle of the treatment tank. The side wall of the first filter screen is attached to the side wall of the treatment tank. The first filter screen can perform secondary filtration on the fibers and impurities in the wastewater.

[0011] By adopting the above technical solution, when the wastewater passes through the grille, the grille cleans the fibers and large impurities in the wastewater, enabling the grille to perform preliminary treatment on the wastewater. Subsequently, the preliminarily treated wastewater passes through the first filter screen. The first filter screen can perform secondary filtration on the fibers and impurities in the wastewater. After that, the treated wastewater flows into the recycling tank through the treatment tank. By setting the filtering element, it is convenient to perform secondary filtration on the fibers and impurities in the wastewater, which is beneficial to the treatment of the wastewater.

[0012] Optionally, it further includes an adsorption assembly. The adsorption assembly includes a fixed frame and an adsorbent. The fixed frame is located on the side of the first filter screen away from the installation frame. The fixed frame is arranged parallel to the first filter screen. A fixing groove is formed on the side wall of the treatment tank. An installation opening is formed at the fixing groove on the side wall of the treatment tank. The installation opening is communicated with the inside of the treatment tank. A sliding groove for placing the side wall of the fixed frame is formed on the side wall of the treatment tank where the installation opening is not provided. The sliding groove is communicated with the installation opening. The fixed frame can slide in the sliding groove. The adsorbent is connected to the fixed frame. The adsorbent is used to adsorb the odor and pigment in the wastewater.

[0013] By adopting the above technical solution, when the wastewater passes through the first filter screen, the wastewater falls onto the adsorption member. By providing the adsorption member, the odor and pigment in the wastewater can be further adsorbed, thereby further treating the wastewater. When it is necessary to replace the adsorption member, the operator only needs to take out the fixing frame from the installation opening and then replace the adsorption member.

[0014] Optionally, the adsorption assembly further includes a fixing member. The treatment tank is provided with an avoidance groove at the installation opening in a direction perpendicular to the fixing frame. The avoidance groove communicates with the fixing groove. The fixing member includes a fixing plate, a sliding rod and a spring. The fixing plate is located in the avoidance groove. The fixing plate is arranged in a direction perpendicular to the fixing frame. The fixing plate is fixed to the treatment tank. The top of the fixing plate is flush with the bottom of the installation opening. The sliding rod is located in the avoidance groove. One end of the sliding rod passes through the fixing plate, and the other end is located in the avoidance groove. The fixing frame is provided with a positioning hole for the sliding rod to insert. The sliding rod is slidably connected to the fixing plate. The spring is sleeved on the outer wall of the sliding rod. One end of the spring is fixed to the fixing plate, and the other end is fixed to the sliding rod.

[0015] By adopting the above technical solution, when it is necessary to replace the adsorption member, first, the operator pulls the sliding rod, and the sliding rod moves away from the fixing plate. At this time, the spring is compressed, and the sliding rod is separated from the positioning hole. Then, the operator takes out the fixing frame from the installation opening, removes the adsorption member on the fixing frame, connects the newly replaced adsorption member to the fixing frame. After that, the operator pulls the sliding rod again, the spring is compressed, installs the fixing frame into the treatment tank through the installation opening, and the operator releases the sliding rod. The spring restores its deformation, and the sliding rod can be inserted into the positioning hole to fix the fixing frame, and the replacement of the adsorption member is completed. By providing the fixing member, on the one hand, it is convenient to replace the adsorption member; on the other hand, the fixing member fixes the fixing frame, which can increase the connection stability between the fixing frame and the treatment tank.

The electrolytic member is located on the side of the fixing frame away from the first filter screen. The electrolytic member is connected to the treatment tank. The electrolytic member is used for electrolyzing the wastewater.

[0017] By adopting the above technical solution, when the wastewater flows into the bottom of the treatment tank through the adsorption member, the electrolytic member is started. The electrolytic member electrolyzes the wastewater. The metal ions released by the electrolytic member form flocculent precipitates with the heavy metal ions and suspended matters in the wastewater. The precipitation process is accelerated by the electric field effect, improving the wastewater treatment efficiency. The electrochemical method does not produce secondary pollution, and the precipitates generated during the treatment process are easy to recycle and treat.

[0018] Optionally, the stirring treatment assembly further includes a stirring member, which includes a rotating shaft, a stirring motor, and a plurality of stirring rods.

[0019] By adopting the above technical solution, when the wastewater flows to the bottom of the treatment tank, the stirring motor is started. The stirring motor can drive the rotating shaft to rotate. During the rotation of the rotating shaft, the stirring rods rotate synchronously with the rotating shaft. During the rotation of the stirring rods, the wastewater can be stirred. By setting to stir the wastewater, the contact area between the wastewater and the electrolysis member can be increased, the mass transfer efficiency can be improved, so that the pollutants in the wastewater can reach the surface of the electrolysis member faster, and the electrolysis reaction can be accelerated. Stirring helps the gas and precipitate generated during the electrolysis process to quickly diffuse from the electrode surface, avoiding the accumulation of bubbles and precipitates on the electrode surface, resulting in electrode passivation and affecting the electrolysis efficiency.

[0020] Optionally, the recovery assembly further includes a rectangular pipe and a second filter screen. The rectangular pipe is connected to the bottom of the treatment tank.

[0021] By adopting the above technical solution, when the electrolyzed wastewater enters the recovery tank, the first valve is opened, and the wastewater passes through the second filter screen and enters the recovery tank. During this process, the second filter screen separates the precipitate generated after the electrolysis of the wastewater from the wastewater. The separated wastewater enters the recovery tank. When it is necessary to clean the second filter screen, the personnel open the cleaning door and clean the second filter screen through the cleaning port. By setting the second filter screen, it is convenient to filter the precipitate generated after the electrolysis of the wastewater.

[0022] Optionally, the recycling component further includes a recycling member, which includes a conduit, a recycling pump, and a detecting member. One end of the conduit communicates with the recycling tank, and the other end passes through the side wall of the treatment tank and extends into the interior of the treatment tank.

The detecting member detects whether the wastewater meets the standard, and the detecting member is electrically connected to the recycling pump.

[0023] By adopting the above technical solution, when the treated wastewater flows into the recycling tank, the detecting member can detect the wastewater. If the wastewater meets the standard, it can be recycled; if the wastewater does not meet the standard, the detecting member transmits a signal to the recycling pump, and the recycling pump pumps the wastewater in the recycling tank along the conduit to the treatment tank for secondary treatment until it meets the standard. By setting the recycling member, it is convenient to treat the wastewater multiple times, so that the wastewater meets the standard.

[0024] Optionally, the electrolysis member includes an electrolysis rod and an insulating sleeve. The electrolysis rod is arranged parallel to the fixed frame.

[0026] By adopting the above technical solution, when the electrolysis rod needs to be cleaned, the power source is started, and the power source pushes the cleaning ring to move along the length direction of the electrolysis rod. During the movement of the cleaning ring, the cleaning cotton moves synchronously with the cleaning ring, and can clean the outer wall of the electrolysis rod. By setting the cleaning member, it is convenient to clean the electrolysis rod, maintain the conductivity of the electrolysis rod, improve the electrolysis efficiency, reduce energy consumption, and lower the operating cost.

[0051] Refer to Figure 5 , the recycling box 64 is communicated with the rectangular pipe 61. The recycling box 64 is placed on the ground. A drain pipe 641 is provided at the bottom of the recycling box 64. The drain pipe 641 is communicated with the recycling box 64. The recycling box 64 is fixedly connected to a drain valve 642 by a flange on the drain pipe 641. The recycling member 65 includes a conduit 651, a recycling pump 652 and a detecting member 653. One end of the conduit 651 is communicated with the recycling box 64, and the other end passes through the side wall of the treatment box 2 and extends into the interior of the treatment box 2. The end of the conduit 651 located inside the treatment box 2 is close to the bottom of the fixed frame 41. The recycling pump 652 is fixedly connected to the conduit 651 close to the recycling box 64 by a flange. The detecting member 653 is fixedly connected to the inner wall of the recycling box 64 by screws. The detecting member 653 can detect whether the wastewater meets the standard. The detecting member 653 is electrically connected to the recycling pump 652. If the wastewater does not meet the standard, the recycling pump 652 pumps the wastewater in the recycling box 64 along the conduit 651 into the treatment box 2 for secondary treatment. If the wastewater meets the standard, it can be recycled.

[0052] The implementation principle of a textile wastewater recycling device according to an embodiment of the present application is as follows: When it is necessary to recycle textile wastewater, first, close the first valve 611 and introduce the wastewater into the treatment tank 2. During this process, the wastewater successively passes through the grille 32 and the first filter screen 341 in the first filtering assembly 3. The grille 32 and the first filter screen 341 can filter the wastewater. The filtered wastewater falls onto the adsorbent 42, and the adsorbent 42 can adsorb the odor and pigment in the wastewater, thereby further treating the wastewater. At the same time, start the stirring member 51 in the stirring treatment assembly 5. The stirring member 51 stirs the wastewater, and the electrolytic member 52 electrolyzes the wastewater, causing the heavy metal ions in the wastewater to precipitate. After the electrolysis is completed, open the first valve 611, and the wastewater flows into the recycling tank 64 through the rectangular pipe 61. The electrolyzed precipitate falls onto the second filter screen 62, and the personnel can clean the precipitate on the second filter screen 62. Subsequently, the detection member 653 detects the wastewater in the recycling tank 64. If the wastewater meets the standards, it can be recycled; if the wastewater does not meet the standards, the detection member 653 transmits a signal to the recycling pump 652, and the recycling pump 652 pumps the wastewater in the recycling tank 64 along the conduit 651 to the treatment tank 2 for secondary treatment until it meets the standards.

[0053] When it is necessary to clean the grille 32, start the driving source 333. The driving source 333 pushes the scraper 331 to move. At the same time, the cleaning agent is sprayed onto the grille 32 through the nozzle 336, and the bristles 332 can clean the grille 32. If it is necessary to clean the first filter screen 341, separate the installation frame 31 from the treatment tank 2, and then the first filter screen 341 can be cleaned. When it is necessary to replace the adsorbent 42, the personnel open the fixed door 26, pull the pull rod, separate the sliding rod 432 from the fixed frame 41, and take out the fixed frame 41, then the adsorbent 42 can be replaced. After the replacement is completed, install the fixed frame 41 on the treatment tank 2.

[0054] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
