Description

Technical Field

[0001] The invention relates to the technical field of printing and dyeing wastewater treatment, and in particular to a printing and dyeing wastewater treatment device and a treatment process. Background Art

[0002] Printing and dyeing, also known as dyeing and finishing, is a processing method, and is also a general term for pre-treatment, dyeing, printing, finishing, washing, etc. Dyeing is the process of automatically transferring the dye from the dye solution to the fiber and forming a uniform, fast and bright color on the fiber;

[0003] A large amount of wastewater is generated during the printing and dyeing process. These wastewaters contain a large amount of pollutants. Discharging them will seriously pollute the natural environment. Therefore, it is generally necessary to use printing and dyeing wastewater treatment equipment to treat the printing and dyeing wastewater to ensure that the wastewater meets the national emission standards. For example, the existing public document CN118791078B-A textile fabric printing and dyeing wastewater treatment equipment, the existing public document CN118304687B-A printing and dyeing wastewater treatment equipment and treatment method, and the existing public document CN111606498B-An organic printing and dyeing wastewater treatment equipment based on magnetized loaded biological carriers disclose a wastewater treatment equipment;

[0004] Although the existing publicly available printing and dyeing wastewater treatment equipment can achieve printing and dyeing wastewater treatment, there are still certain shortcomings in actual use: first, the existing printing and dyeing wastewater treatment equipment is limited to use in various venues due to its large overall volume during use, and has poor adaptability; second, the existing printing and dyeing wastewater treatment equipment uses a cutting mechanism to treat floating objects intercepted on the surface of the filter screen during use, and this method of treating the mechanism is in wastewater with high acid and alkali concentrations for a long time, which affects the service life, and is affected by the depth of the wastewater, and also affects the efficiency of salvage and wastewater introduction; finally, when the existing printing and dyeing wastewater treatment equipment is in use, the position of the aerator remains unchanged and is fixed in the wastewater treatment tank. When adjusting the aeration intensity, it needs to be controlled and adjusted by an external device, and the adjustment of the aeration intensity consumes a lot of energy, resulting in high energy consumption; therefore, it is necessary to improve the existing technology to solve the above technical problems.

In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included. Example 1

[0046] Reference Figure 1 , Figure 2 , Figure 4 and Figure 6 , which is the first embodiment of the present invention, provides a printing and dyeing wastewater treatment equipment. The printing and dyeing wastewater treatment equipment modularizes the pretreatment device and the biological treatment cylinder 300 to be suitable for sites of different sizes and reduce the occupied area.

[0047] Specifically, a wastewater filter frame 100, wherein solid collection frames 101 are symmetrically fixed above both side walls of the wastewater filter frame 100; a wastewater tank 200, wherein the interior of the wastewater tank 200 is connected to the wastewater filter frame 100 through a pipeline, and the wastewater tank 200 is located on the lower side of the wastewater filter frame 100; a biological treatment cartridge 300, wherein the biological treatment cartridge 300 is connected to the wastewater tank 200 through a pipeline; a pretreatment assembly 400, comprising a second motor 401 installed on the rear end surface of the solid collection frame 101 and an output shaft of the second motor 401 installed on the output shaft of the second motor 401 The second driving pulley 401a is connected to the first driven pulley 402a through a belt, and a first threaded rod 402 is installed in the middle of the inner wall of the first driven pulley 402a; and a connecting assembly 500, including a first fixed frame 501 fixed on the rear end face of the solid collection frame 101 and a second threaded rod 502 rotatably installed on the inner wall of the first fixed frame 501, the other end of the second threaded rod 502 passes through the bearing on the inner wall on the other side of the first fixed frame 501 and is connected to the first rotating plate 502a.

[0048] For details, please refer to Figure 4 , Figure 5 and Figure 6 The two ends of the first threaded rod 402 are rotatably mounted in the internal bearings of the first bracket 403 and the second bracket 404, respectively. A spline groove 402b is provided in the middle of both end surfaces of the first threaded rod 402. A first moving block 405 is spirally sleeved on the outer wall of the first threaded rod 402. A connecting plate 406 is installed on the front end surface of the first moving block 405. Connecting rods 406a are fixed on both ends of the front surface of the connecting plate 406. The other end of the connecting rod 406a passes through the adjacent strip hole 102 and is connected to the adjacent elastic net 407. The elastic net 407 The front end of the lower surface of the first bracket 403 and the second bracket 404 are fixedly provided with an elastic tooth plate 407a; wherein, the front ends of the first bracket 403 and the second bracket 404 are fixedly provided on the outer wall of the adjacent solid collection frame 101, and one end of the elastic net 407 is fixedly provided on the inner wall of the wastewater filter frame 100; the second moving block 503 is spirally sleeved on the outer wall of the second threaded rod 502, and a connecting shaft 504 is rotatably installed in the front end bearing of the second moving block 503, and a spline shaft 504a is fixedly provided in the middle of both side walls of the connecting shaft 504, and the spline shaft 504a is inserted into the adjacent spline groove 402b;

[0049] When the above arrangement is in use, the printing and dyeing wastewater can be pre-treated through the wastewater filter frame 100, and after the pre-treatment of the printing and dyeing wastewater, the wastewater is introduced into the wastewater pool 200 through the pipeline, and then the printing and dyeing wastewater is pumped into the biological treatment cylinder 300 for further treatment. Since the wastewater pool 200 is generally planned and adjusted according to the size of the construction site, and the overall volume of the current printing and dyeing wastewater treatment equipment is relatively large, it is impossible to make corresponding adjustments according to the volume of the wastewater pool 200 in the existing site, resulting in poor adaptability. Among them, the original pretreatment device and the wastewater biological treatment cylinder 300 are modularly designed and processed, and adjacent pretreatment devices are connected by a connecting component 500. When in use, force is applied to the first rotating plate 502a to drive the second threaded rod 502 to rotate, and the external thread on the outer wall of the second threaded rod 502 is spirally matched with the internal thread in the wall of the threaded hole on the second moving block 503, so the second threaded rod 50 2 will drive the second moving block 503 to move when rotating, so that the connecting shaft 504 moves, and the spline shaft 504a at its outer end is inserted into the spline groove 402b on the first threaded rod 402 in the adjacent pretreatment component 400 to realize the connection between the adjacent pretreatment devices. When in use, multiple pretreatment devices can be used through a single set of second motors 401, and the biological treatment cylinder 300 can be sleeved on the outer walls of the first active pulley 302a and multiple second driven pulleys 706b through belts of different lengths to realize the transmission connection between the driving mechanisms of multiple sets of biological treatment cylinders 300. Therefore, during use and installation, corresponding adjustments can be made according to the area of ​​the wastewater pool 200 in the site. Among them, after modularization, the pretreatment device and the wastewater biological treatment cylinder 300 can be used separately, or they can be connected and used synchronously through the connecting component 500, which is convenient for expansion and site adaptation and reduces the occupied area.

[0050] Furthermore, a waste port is provided at the bottom of the solid collection frame 101 for processing floating objects in wastewater. The second motor 401 can be operated in forward and reverse directions as needed to ensure the reciprocating motion of the two sets of elastic nets 407. The first bracket 403 and the second bracket 404 are used to assist in limiting the first threaded rod 402 and to achieve a rotation effect. The elastic net 407 can be flipped, bent and extended, and the spline shaft 504a can move inside the spline groove 402b to realize plug-in transmission operations.

[0051] Read in detail Figure 1 , Figure 3 , Fig. 9 and Fig.10As shown, strip holes 102 are alternately opened on both sides of the rear end faces of the wastewater filter frame 100 and the solid collection frame 101, and a grinding frame 103 is fixedly provided on the inner wall of the solid collection frame 101; fixed pulleys 301 are symmetrically installed on the front and rear ends of the top of the biological treatment cylinder 300, a first motor 302 is installed on the upper side of the biological treatment cylinder 300, a first driving pulley 302a is installed on the output shaft of the first motor 302, a filter screen 303 is installed in the middle of the inner wall of the biological treatment cylinder 300, and a biofilm frame 304 is arranged directly below the filter screen 303.

[0052] Furthermore, a plurality of grinding balls are provided on the surface of the grinding frame 103, which can be used to grind floating objects attached to the surface of the elastic net 407 for subsequent flushing treatment. The fixed pulley 301 can limit and assist the rotation of the belt when the aeration assembly 700 in the adjacent biological treatment cylinder 300 needs to be connected by a belt, thereby avoiding the belt from being worn. The biological treatment cylinder 300, the filter screen 303 and the biofilm frame 304 are all existing technologies, so they will not be described in detail here. Example 2

The driving box 602 is connected to a diverter plate 603 via a pipeline above, and nozzles 603a are arranged in an array from front to back on the outer wall of the diverter plate 603; wherein the water tank 601 and the driving box 602 are connected via a pipeline, the rack on the outer wall of the toothed disc 602d meshes with the rack on the adjacent elastic toothed plate 407a, and a nozzle is arranged on the outer wall of the nozzle 603a;

[0055] When the above arrangement is used, after the printing and dyeing wastewater is passed into the wastewater filter frame 100, the floating objects in the wastewater will be filtered out by the elastic net 407, and then the second motor 401 is started, and the output shaft of the second motor 401 rotates to drive the second driving pulley 401a to rotate, and the outer wall of the second driving pulley 401a is connected to the outer wall of the first driven pulley 402a through a belt, so when the second driving pulley 401a rotates, it will drive the first driven pulley 402a to rotate, and make the first threaded rod 402 inside the first driven pulley 402a rotate , wherein the external thread on the outer wall of the first threaded rod 402 is meshed with the internal thread in the wall of the threaded hole on the first moving block 405, so when the first threaded rod 402 rotates, it will drive the first moving block 405 to move along its outer wall, and the movement of the first moving block 405 will drive the two sets of elastic nets 407 to move through the connecting plate 406 and the connecting rod 406a, wherein one set of elastic nets 407 will be rolled up and turned over to the solid collection frame 101 on one side, and the other set of elastic nets 407 will be unfolded from the solid collection frame 101 on the other side and laid flat on the wastewater In the filter frame 100, the printing and dyeing wastewater is continuously filtered, and the elastic net 407 with floating objects on the surface will contact the surface of the grinding frame 103 during the flipping process to the solid collection frame 101, so that the floating objects are ground and processed, and the elastic net 407 will drive the elastic tooth plate 407a to move during the flipping process, and the rack on the elastic tooth plate 407a is meshed with the rack on the outer wall of the tooth plate 602d, so the elastic tooth plate 407a will drive the tooth plate 602d to rotate when it moves, and drive the main shaft 602c to rotate under the action of the driving shaft 602c. The driving water wheel 602b rotates, and cooperates with the auxiliary water wheel 602a to pump water in the water tank 601 into the nozzle 603a, and then sprays it onto the surface of the elastic net 407 through the nozzle on the nozzle 603a, so that the filtering structure can be flushed, thereby reducing the corrosion of the floating object treatment mechanism by the wastewater, ensuring the service life, and realizing continuous filtration of floating objects in the wastewater to avoid affecting the wastewater introduction efficiency. When the printing and dyeing wastewater is continuously filtered and treated, the second motor 401 can be driven forward and reversely to realize the reciprocating motion of the two sets of elastic nets 407.

A plurality of aeration holes 706a are provided on the outer wall of the aeration tube 706. A second driven pulley 706b is sleeved on one side of the outer wall of the aeration tube 706. An annular magnetic sheet 708 is sleeved on the outer wall of the aeration tube 706 in a horizontal array and slidingly sleeved. A fourth threaded rod 707a is spirally fitted in the threaded holes on the plurality of annular magnetic sheets 708. One end of the fourth threaded rod 707a is rotatably mounted in the bearing on the second side plate 705. The other end of the fourth threaded rod 707a passes through the bearing on the first side plate 704 and is connected to the third rotating plate 707. The second fixed frame 703 is fixed on the outer wall of the biological treatment cylinder 300. The plurality of annular magnetic sheets 708 are sleeved on the outer wall of the guide rod 704a.

[0059] When the above arrangement is in use, after the printing and dyeing wastewater enters the biological treatment barrel 300, the first motor 302 is started, and the output shaft of the first motor 302 rotates to drive the first active pulley 302a to rotate, and the outer wall of the first active pulley 302a is connected to the outer wall of the second driven pulley 706b through a belt, so when the first active pulley 302a rotates, it will drive the second driven pulley 706b to rotate synchronously, and the rotation of the second driven pulley 706b will drive the aeration pipe 706 and the multiple groups of annular magnetic sheets 708 on its outer wall to rotate, thereby increasing the oxygen content in the wastewater and magnetizing the wastewater. When the aeration intensity needs to be adjusted, force is first applied to the third rotating plate 707, and the third rotating plate 707 is forced to drive the fourth threaded rod 707a to rotate, and the external thread on the outer wall of the fourth threaded rod 707a is connected to the thread on the annular magnetic sheet 708. The internal threads in the hole walls are meshed, so when the fourth threaded rod 707a rotates, it will drive the multiple groups of annular magnetic plates 708 to translate under the assistance of the guide rod 704a, and when the multiple groups of annular magnetic plates 708 move, they can block the adjacent aeration holes 706a, so as to achieve the purpose of adjusting the number of aeration holes 706a. After the number of aeration holes 706a is adjusted, force is applied to the second rotating plate 702a, and the second rotating plate 702a is driven by the force to rotate the third threaded rod 702, and the external threads on the outer wall of the third threaded rod 702 are meshed with the internal threads in the wall of the threaded hole on the cross 701, so the rotation of the third threaded rod 702 will drive the cross 701 to adjust its height, and then the height of the aeration pipe 706 in the wastewater in the biological treatment cylinder 300 can be adjusted, so as to achieve the purpose of adjusting the aeration intensity, so as to reduce the activation of external aeration equipment and reduce energy consumption.

[0060] Furthermore, the height adjustment of the aeration tube 706 is achieved through the spiral cooperation between the third threaded rod 702 and the cross 701. The guide rod 704a limits and guides the annular magnetic sheet 708. The annular magnetic sheet 708 is slidably mounted on the outer wall of the aeration tube 706, so when the aeration tube 706 rotates, the annular magnetic sheet 708 can be driven to rotate. At the same time, the annular magnetic sheet 708 can move along the outer wall of the aeration tube 706. The synchronous movement of multiple groups of annular magnetic sheets 708 can be adjusted by the fourth threaded rod 707a. Example 4
