Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and in particular to environmentally friendly purification equipment for textile dyeing and printing wastewater. Background Art

[0002] Textiles, that is, products processed by textiles, include yarn, woven fabrics, knitted fabrics, braided fabrics, etc. They are divided into two categories: woven fabrics and knitted fabrics. However, wastewater is generated in the process of textile manufacturing. With the development of science and technology, people pay more and more attention to environmental issues and the treatment of textile wastewater.

[0003] At present, with the development of society, in the production and manufacturing of textiles, wastewater treatment is involved. Usually, the wastewater needs to be purified before discharge. During the purification, chemicals need to be added to the wastewater to remove the chemical substances in the wastewater. However, the wastewater generated by textile dyeing and printing currently contains a certain amount of fiber impurities. These fiber impurities cannot react with chemical agents to form precipitation and are still suspended in the wastewater. Separate filtration work is required to filter out these fiber impurities. The existing technology uses a filter to filter the fiber impurities, which is inefficient. The filter cannot quickly discharge the water, which leads to slow flow of wastewater. With the accumulation of fibers, the filter is blocked and cannot be filtered. Regular filter cleaning is required, which greatly reduces the wastewater treatment efficiency.

[0004] In order to solve the above problems, we proposed an environmentally friendly purification equipment for textile dyeing and printing wastewater. Summary of the invention

[0005] The purpose of the present invention is to solve the problems in the background technology and to propose an environmentally friendly purification device for textile dyeing and printing wastewater.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an environmentally friendly purification device for textile dyeing and printing wastewater, comprising a reagent reaction box, a cylindrical cleaning box is fixedly connected to the upper end of the reagent reaction box, a connecting column that is rectangular in top view is rotatably connected to the center of the bottom wall of the cleaning box, a placing frame with an upper end opening is fixedly connected to the outer walls of the connecting column, a frame opening is opened on both side walls of each placing frame, and a plurality of equally spaced baffles are fixedly connected to each frame opening, a cross-shaped connecting socket is vertically opened at the upper end of the connecting column, the connecting socket is connected to four placing frames, and a liquid injection pipe is connected to the outer end of the cleaning box;

[0007] The left and right ends of the pharmaceutical reaction box are fixedly connected to support plates, and the upper ends of the two support plates are fixedly connected to a cleaning box with an opening at the upper end and a rectangular shape. The ends of the two cleaning boxes that are away from each other are vertically slidably connected to two vertical plates, and two sliding rods arranged parallel to each other in front and behind are fixedly connected between the four vertical plates. Four sliding sleeves distributed in a rectangular shape are slidably sleeved on the two sliding rods, and a circular top plate is fixedly connected to the lower ends of two sliding sleeves in the same front and back positions on the sliding rods, one of the top plates corresponds to the position of the cleaning box up and down, and the other top plate is located above the cleaning box, and a second motor is fixedly installed at the center position of the upper ends of the two top plates, and the output ends of the second motors pass through the top plates and are coaxially fixedly connected to a cross-shaped connecting plug block at the bottom, and the connecting plug block matches the connecting socket and is fixedly connected to a plate-shaped filter element on the surrounding outer walls.

[0008] In the above-mentioned environmentally friendly purification equipment for textile dyeing and printing wastewater, two circumferentially distributed and fan-shaped connecting ports are opened on the inner bottom wall of the cleaning box, and a rotating ring is rotatably connected to the center position of the inner top wall of the chemical reaction box. Two evenly circumferentially distributed fan-shaped plates are fixedly connected to the outer peripheral surface of the rotating ring. The fan-shaped plates fit the inner top wall of the chemical reaction box and are slidably connected thereto. The inner circle diameter of the fan-shaped plates is smaller than the inner circle diameter of the connecting port, and the outer circle diameter of the fan-shaped plates is larger than the outer circle diameter of the connecting port.

[0009] In the above-mentioned environmentally friendly purification equipment for textile dyeing and printing wastewater, the outer end of one of the fan-shaped plates is fixedly connected to an arc-shaped tooth plate, and a first gear meshing with the arc-shaped tooth plate is rotatably connected to the top wall of the reagent reaction box. A first motor that drives the first gear to rotate is fixedly installed at the lower end of the reagent reaction box, and a drain pipe is connected to the lower end of the reagent reaction box.

[0010] The cam is connected with the two guide wheels, and the guide wheels are connected with the two guide wheels respectively, and the guide wheels are connected with the two guide wheels respectively, and the two guide wheels are connected with the two guide wheels respectively.

[0011] In the above-mentioned environmentally friendly purification equipment for textile dyeing and printing wastewater, two vertical blocks arranged at intervals are fixedly connected to the inner walls around the two cleaning boxes, and each of the vertical blocks is provided with a plurality of longitudinally arranged cleaning nozzles. Drying fans are fixedly installed on the inner bottom wall of the cleaning box and at four angular positions, and the air outlet end of the drying fan is arranged upward toward the central axis of the cleaning box.

[0012] Compared with the existing technology, the advantages of this environmentally friendly purification equipment for textile dyeing and printing wastewater are:

[0013] By setting a cleaning box, a connecting column, a placing frame and a plate filter element, when the plate filter element is placed in the cleaning box, the top plate cover is set on the cleaning box, and then only the connecting port needs to be closed, and then the wastewater is passed into the cleaning box, and the plate filter element is driven by a second motor to rotate together with the placing frame to adsorb the fiber impurities suspended in the wastewater in the cleaning box, thereby removing the fiber impurities from the textile dyeing and printing wastewater. The textile dyeing and printing wastewater after removal is discharged into the chemical reaction box by opening the connecting port, and the chemical is added and reacted, and then discharged after the reaction, thereby ensuring that the wastewater after the subsequent chemical reaction does not contain fiber impurities and ensuring the subsequent wastewater purification effect.

[0014] After a certain period of filtering and adsorption, the adsorption and filtering effects of the plate-shaped filter element in the cleaning box are reduced. At this time, it is only necessary to move it out of the cleaning box and use the third motor to translate it to the cleaning box on the same side, so that the plate-shaped filter element on the other side can be moved to the cleaning box, and then the top plate can be moved down to replace the new plate-shaped filter element in the cleaning box, so as to carry out normal adsorption of fiber impurities in time, and the plate-shaped filter element in the cleaning box can automatically complete the cleaning work and wait for secondary use.

[0015] In summary, the present invention can automatically replace and clean the filter element while effectively filtering fibers and impurities from textile dyeing and printing wastewater, thereby greatly improving the treatment efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Example

[0024] Reference Figure 1-Figure 6 , an environmentally friendly purification device for textile dyeing and printing wastewater, comprising a reagent reaction box 1, the reagent reaction box 1 is used for the reaction and mixing of textile dyeing and printing waste and reagents, the reagent reaction box 1 is provided with a reagent addition port (not shown in the figure), the upper end of the reagent reaction box 1 is fixedly connected to a cylindrical cleaning box 2, the center position of the inner bottom wall of the cleaning box 2 is rotatably connected to a connecting column 3 that is rectangular in top view, and the outer walls around the connecting column 3 are fixedly connected to a placing frame 4 with an upper end opening, and the connecting column 3 can rotate together with the placing frame 4. A frame opening 5 is opened on the two side walls of each placing frame 4, and a plurality of equally spaced baffles 6 are fixedly connected in each frame opening 5, a cross-shaped connecting socket 7 is vertically opened on the upper end of the connecting column 3, and the connecting socket 7 is connected to four placing frames 4, and an injection pipe 14 is connected to the outer end of the cleaning box 2, and the injection pipe 14 is used to inject the textile dyeing and printing wastewater to be treated into the cleaning box 2.

[0025] Two circumferentially distributed and fan-shaped connecting openings 8 are provided on the inner bottom wall of the cleaning box 2. The cleaning box 2 and the pharmaceutical reaction box 1 are connected to each other through the connecting openings 8. A rotating ring 9 is rotatably connected to the center position of the inner top wall of the pharmaceutical reaction box 1. Two evenly circumferentially distributed fan-shaped plates 10 are fixedly connected to the outer circumferential surface of the rotating ring 9. The fan-shaped plates 10 fit the inner top wall of the pharmaceutical reaction box 1 and are slidably connected thereto. The inner ring diameter of the fan-shaped plates 10 is smaller than the inner ring diameter of the connecting opening 8, and the outer ring diameter of the fan-shaped plates 10 is larger than the outer ring diameter of the connecting opening 8. The fan-shaped plates 10 can be rotated by the setting of the rotating ring 9, and when the two fan-shaped plates 10 are rotated to the corresponding positions of the two connecting openings 8, the two connecting openings 8 can be blocked, so that the cleaning box 2 and the pharmaceutical reaction box 1 cannot be connected. The outer end of one of the sector plates 10 is fixedly connected with an arc-shaped tooth plate 11, and a first gear 12 meshing with the arc-shaped tooth plate 11 is rotatably connected on the top wall of the medicine reaction box 1. A first motor 13 driving the first gear 12 to rotate is fixedly installed at the lower end of the medicine reaction box 1. The first motor 13 can drive the first gear 12 to rotate. The engagement of the first gear 12 with the arc-shaped tooth plate 11 can drive the sector plate 10 to rotate. When the two sector plates 10 rotate synchronously, the rotation of the first motor 13 can be used to control the opening and closing of the communication port 8, thereby controlling whether the waste water in the cleaning box 2 is discharged into the medicine reaction box 1. The lower end of the medicine reaction box 1 is connected with a drain pipe 37 for discharging the waste water in the medicine reaction box 1.

[0026] The left and right ends of the reagent reaction box 1 are fixedly connected to support plates 15, and the upper ends of the two support plates 15 are fixedly connected to a cleaning box 16 with an upper end opening and a rectangular shape. The ends of the two cleaning boxes 16 that are far away are vertically slidably connected to two vertical plates 17, and two sliding rods 18 arranged parallel to each other are fixedly connected between the four vertical plates 17. Four sliding sleeves 19 distributed in a rectangular shape are slidably sleeved on the two sliding rods 18. The lower ends of the two sliding sleeves 19 in the same front and rear positions on the sliding rods 18 are fixedly connected to a circular top plate 20, and one of the top plates 20 corresponds to the position of the cleaning box 2 up and down. , the other top plate 20 is located above the cleaning box 16, and the second motor 21 is fixedly installed at the center position of the upper end of the two top plates 20. The output end of the second motor 21 passes through the top plate 20 and is coaxially fixedly connected with a cross-shaped connecting block 22 at the bottom. The connecting block 22 matches the connecting socket 7 and the outer walls are fixedly connected with a plate-shaped filter element 23. The two top plates 20 can move laterally along the two sliding rods 18 through the sliding sleeve 19. When the connecting block 22 under one top plate 20 corresponds to the position of the connecting socket 7 in the cleaning box 2, the connecting block 22 can be inserted into the connecting socket 7 of the connecting column 3, so that the four plate-shaped filter elements 23 are inserted into the four insertion frames 4, and then the second motor 21 can use the connecting block 22 to drive the connecting column 3 and the four insertion frames 4 to rotate, while the connecting block 22 and the four plate-shaped filter elements 23 on the other side are in the cleaning box 16 on the same side.

[0027] Specifically, when the plate-shaped filter element 23 is placed in the cleaning box 2, the top plate 20 is covered on the cleaning box 2, and then the connecting port 8 only needs to be closed, and then the wastewater is passed into the cleaning box 2. The plate-shaped filter element 23 is driven by the second motor 21 to rotate together with the placing frame 4, and the fiber impurities suspended in the wastewater in the cleaning box 2 are adsorbed, thereby removing the fiber impurities from the textile dyeing and printing wastewater. The textile dyeing and printing wastewater after removal is discharged into the drug reaction box 1 by opening the connecting port 8, and the drug is added and reacted, and then discharged after the reaction.

[0028] The front and rear ends of the two top plates 20 are both fixedly connected with a fixed transverse plate 24 , and the fixed transverse plate 24 serves to connect the two top plates 20 . The lower ends of the two fixed transverse plates 24 are fixedly connected to two end blocks 25 distributed on the left and right, and two baffles 26 arranged at intervals in front and behind are fixedly connected between every two corresponding end blocks 25 on the left and right. Each baffle 26 is horizontally provided with a slide 27, and the front and rear ends of the pharmaceutical reaction box 1 are fixedly installed with vertically arranged telescopic cylinders 28, and the telescopic ends of the two telescopic cylinders 28 extend to the bottom of the two fixed transverse plates 24 respectively and are fixedly connected with support frames 29, and the upper ends of the support frames 29 are fixedly connected with a moving frame 30, and the moving frame 30 is slidably connected between the two corresponding baffles 26 above, and the front and rear ends of the moving frame 30 are fixedly connected with two sliders 31, and the sliders 31 are slidably connected in the corresponding slides 27, and the second gears 33 are rotatably connected between the front and rear inner walls of the two moving frames 30, and the third motors 32 for driving the corresponding second gears 33 to rotate are fixedly installed on the outer sides of the two moving frames 30, and the lower ends of the two fixed transverse plates 24 are provided with racks, and the second gears 33 are meshed with the corresponding racks above.

[0029] By setting two telescopic cylinders 28, when the two cylinders work synchronously, they can drive the two fixed horizontal plates 24 to move up and down, thereby controlling the lifting and lowering of the two top plates 20. By using the third motor 32 and the second gear 33, the two third motors 32 can control the lateral movement of the two top plates 20 when they work synchronously. Specifically, after a certain period of filtration and adsorption, the adsorption and filtration effects of the plate-shaped filter element 23 in the cleaning box 2 are reduced. At this time, it is only necessary to move it out of the cleaning box 2 and use the third motor 32 to translate it to the cleaning box 16 on the same side, so that the plate-shaped filter element 23 on the other side is moved to the cleaning box 2, and then the top plate 20 is moved down, so that a new plate-shaped filter element 23 is replaced in the cleaning box 2, and the normal adsorption of fiber impurities is carried out in time.

[0030] Two vertical blocks 34 arranged at intervals are fixedly connected to the inner walls around the two cleaning boxes 16, and each vertical block 34 is provided with a plurality of cleaning nozzles 35 arranged longitudinally. Drying fans 36 are fixedly installed on the inner bottom wall of the cleaning box 16 and at four angles. The air outlet end of the drying fan 36 is arranged upward toward the central axis of the cleaning box 16. Specifically, after the plate-like filter element 23 is replaced, the plate-like filter element 23 located in the cleaning box 16 can be cleaned by high-pressure flushing of the cleaning nozzle 35 to remove fiber impurities adsorbed on the surface, and after cleaning, the four drying fans 36 can be used to dry the surface in time, blow away surface impurities, and complete the automatic cleaning of the plate-like filter element 23, so as to wait for the next use.
