Description

Technical Field

[0001] This utility model relates to the field of chemical wastewater treatment technology, and in particular to a flocculant for chemical wastewater treatment. Background Technology

[0002] Chemical production generates a lot of wastewater, which contains a large number of impurities and harmful components. Therefore, it needs to be purified through multiple processes before it can be discharged to prevent harmful substances in the wastewater from damaging the natural environment.

[0003] The flocculation process is an important step in the purification and treatment of chemical wastewater. It can aggregate tiny particles in the wastewater into larger flocs, which can then be removed after sedimentation. This removes the solid components from the chemical wastewater. Furthermore, flocculants can degrade harmful substances such as phosphorus and nitrogen, preventing eutrophication of water bodies. In addition, they can also remove pollutants such as emulsified oil and color ions from the water.

[0004] Chinese utility model patent application number CN202211241980.5 describes a treatment device for wastewater from the production of solution-polymerized styrene-butadiene rubber. This device uses a rotary drive mechanism to rotate a filter barrel, throwing flocculated material from the wastewater onto the inner wall of the filter barrel. Then, a guide arc plate scrapes the flocculated material from the inner wall of the filter barrel onto the first and second rollers for squeezing and drainage. However, this treatment device separates the flocculated material from the water through centrifugal rotation of the filter barrel. This requires a high rotational speed for the filter barrel, limiting its size and thus reducing the separation speed and efficiency of the device in treating chemical wastewater. Utility Model Content

[0005] The purpose of this invention is to provide a flocculant for chemical wastewater treatment, in order to solve the problem of low efficiency in existing chemical wastewater treatment devices when treating chemical wastewater by flocculation, as mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flocculant for chemical wastewater treatment, comprising a lifting device, a top plate, a treatment tank, and a collection box. The top plate is connected to the lifting device and can be submerged at the bottom of the treatment tank. Two pairs of first pull ropes are symmetrically fixedly connected to the bottom of the top plate. The ends of the two pairs of first pull ropes away from the top plate are symmetrically fixedly connected to two fixed frames via pull rings. The gap between the front, rear, left, and right sides of the two fixed frames and the inner wall of the treatment tank is less than five centimeters. Two filter screens are symmetrically connected between the inner walls of the two fixed frames. Two pairs of hinge rods are symmetrically fixedly connected to the sides of the two fixed frames that are close to each other. The two pairs of hinge rods are symmetrically hinged to the top of the collection box via two hinge axes with collinear axes. A connecting assembly is connected to the collection box.

[0007] The connecting assembly is used to connect the two fixed frames and the collection box together to restrict the rotation of the fixed frames about the hinge axis.

[0008] Preferably, the connecting assembly includes two mounting cavities symmetrically formed inside the collection box, with the left and right ends of the two mounting cavities penetrating the left and right side walls of the collection box, respectively. Two limiting rods are symmetrically and elastically inserted into two pairs of the left and right sides of the two mounting cavities. Two pairs of limiting holes are symmetrically formed on the adjacent sides of the two fixing frames, and the two pairs of limiting rods can be inserted into the two pairs of limiting holes respectively. The connecting assembly also includes two pulling mechanisms connected within the two mounting cavities, and the two pulling mechanisms are respectively connected to the adjacent ends of the two pairs of limiting rods to connect the two pairs of... The limiting rods are pulled in the same direction. The advantage of this design is that by pulling the two pairs of limiting rods in the same direction through the pulling mechanism, the two pairs of limiting rods can be pulled out from the two pairs of limiting holes. This allows the two fixed frames to rotate around the hinge axis so that the top surfaces of the two filter screens come close to each other. This allows the flocculated material trapped on the top surface of the filter screen to slide down the filter screen and into the collection box. With a sufficiently large filter screen area, this can achieve rapid separation of water and flocculated material, effectively improving the flocculation treatment efficiency of chemical wastewater.

[0009] Preferably, the pulling mechanism includes two pairs of limiting plates symmetrically fixedly connected in two mounting cavities, two pairs of limiting rods symmetrically and movably inserted into the two pairs of limiting plates, two baffles symmetrically fixedly connected to the adjacent ends of the two pairs of limiting rods, two pairs of elastic elements symmetrically fixedly connected between the two baffles and the two limiting plates, two pairs of second pull ropes symmetrically fixedly connected to the adjacent sides of the two baffles, and two third pull ropes symmetrically fixedly connected to the ends of the two pairs of second pull ropes away from the baffles. The pulling mechanism also includes two cylinders symmetrically fixedly connected to the top of the top plate. The output end of the cylinder penetrates the bottom surface of the top plate, and the top ends of the two third pull ropes penetrate the top wall of the collection box and are fixedly connected to the output ends of the two cylinders respectively. The advantage of this arrangement is that when the two cylinders are activated to retract, the two cylinders pull the third pull ropes upward. The two third pull ropes overcome the resistance of the two pairs of elastic elements through the two pairs of second pull ropes and pull the two pairs of limit rods in a direction closer to each other. This allows the limit rods to be quickly and reliably pulled out of the limit holes, realizing the separation between the two fixed frames and the collection box, and ensuring that the ends of the two fixed frames that are far apart can rotate upward to complete the collection of flocculated matter.

[0010] Preferably, the two filter screens are symmetrically connected to the front and rear inner walls of the two fixed frames via a first rotating rod and a first torsion spring at their closest points. The two filter screens are arranged in a figure-eight shape. The device also includes two vibration components symmetrically arranged on the inner walls of the two fixed frames. The two vibration components are used to cooperate with the first rotating rod and the first torsion spring to drive the two filter screens to vibrate back and forth. The advantage of this arrangement is that the vibration of the filter screens can make the flocculated material on the top surface of the filter screens slide more thoroughly into the collection box, avoiding the flocculated material from adhering to the top surface of the filter screens and clogging the filter holes, thereby improving the reliability and practicality of the flocculant.

[0011] Preferably, the vibration assembly includes two rectangular plates symmetrically fixedly connected to the inner walls of two fixed frames away from each other. Two sets of through cavities are symmetrically opened on the adjacent sides of the two rectangular plates. The top and bottom ends of the through cavities penetrate the top and bottom surfaces of the rectangular plates, respectively. The vibration assembly also includes two pairs of arc-shaped impact rods symmetrically connected to the ends of the two filter screens away from each other. The circles corresponding to the two pairs of impact rods coincide with the axis of the hinge shaft. The vibration assembly also includes a drive mechanism connected to the bottom of the top plate. The drive mechanism is used to push the two pairs of first pull ropes in the opposite direction. The advantage of this arrangement is that when the drive mechanism is activated, it pushes the two pairs of first pull ropes in the opposite direction, so that the ends of the two fixed frames away from the hinge rods move back and forth, so that the two pairs of impact rods can collide intermittently. In conjunction with the first torsion spring and the first rotating rod, the ends of the two filter screens away from the first rotating rod can collide with the rectangular plates in a reciprocating manner, so that the filter screens are vibrated to ensure that the flocculated material attached to the top surface of the filter screens can slide smoothly and completely into the collection box.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] 1. In this utility model, the two fixed frames and the collection box are connected together by a connecting component. Then, the hoisting equipment is started to pull the top plate upward and pull the two filter screens upward through the first pull rope until the two filter screens are moved directly above the treatment tank. This allows the flocculated material in the treatment tank to be trapped on the top surface of the two filter screens. Subsequently, the fixed frames and the collection box are separated. At this time, the ends of the two fixed frames away from the hinge axis rotate upward until the two filter screens are close together. At this time, the two filter screens are arranged in an inverted V-shape, so that the flocculated material on the top surface of the filter screens can slide into the collection box. Furthermore, the gap between the front, back, left, and right sides of the two fixed frames and the inner wall of the treatment tank is less than five centimeters. This allows for the rapid separation of flocculated material and water in the entire treatment tank, effectively improving the flocculation treatment efficiency of the flocculant.

[0014] 2. In this utility model, the vibration component is set to activate the drive mechanism to push the two pairs of first pull ropes on the left and right in opposite directions. This causes the ends of the two fixed frames away from the hinge rod to move back and forth, so that the two pairs of collision rods can collide intermittently. This, together with the first torsion spring and the first rotating rod, causes the ends of the two filter screens away from the first rotating rod to collide with the rectangular plate, thereby causing the filter screens to vibrate. This ensures that the flocculated material attached to the top surface of the filter screens can slide smoothly and completely into the collection box. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Example 1

[0026] Please refer to Figures 1-7 The flocculant shown is for chemical wastewater treatment and includes a lifting device (an existing mature device, not shown in the figure), a top plate 1, a treatment tank 2, and a collection box 6. The right and left sides of the treatment tank 2 are respectively connected to an inlet pipe 21 and a drain pipe 22. The top plate 1 is connected to the lifting device and can be submerged at the bottom of the treatment tank 2. Two pairs of first pull ropes 3 are symmetrically fixed to the bottom of the top plate 1. Two fixed frames 4 are symmetrically fixed to the ends of the two pairs of first pull ropes 3 away from the top plate 1 via pull rings. The gap between the front, rear, left, and right sides of the two fixed frames 4 and the inner wall of the treatment tank 2 is less than five centimeters. Two filter screens 5 are symmetrically connected between the inner walls of the two fixed frames 4. Two pairs of hinge rods 61 are symmetrically fixed to the sides of the two fixed frames 4 that are close to each other. The two pairs of hinge rods 61 are symmetrically hinged to the top of the collection box 6 via two hinge axes with collinear axes. A connecting assembly 7 is connected to the collection box 6.

[0027] Two guide plates 9 are symmetrically fixed to the sides of the two fixed frames 4 that are close to each other, which allows the flocculated material to slide more smoothly and completely into the collection box 6 along the guide plates 9.

[0028] Two pairs of slots 62 are symmetrically provided on the sides of the two fixed frames 4 that are close to each other. The bottom of the two pairs of slots 62 penetrates the bottom surface of the fixed frame 4. Two pairs of plates 63 are symmetrically fixedly connected to the left and right sides of the collection box 6. The two pairs of plates 63 can be inserted into the two pairs of slots 62 respectively, which can better restrict the position between the two fixed frames 4 and the collection box 6, and ensure that the two pairs of limiting rods 72 can be smoothly inserted into the two pairs of limiting slots.

[0029] The connecting component 7 is used to connect the two fixed frames 4 and the collection box 6 together to restrict the fixed frames 4 from rotating about the hinge axis.

[0030] refer to Figures 1-4 The connecting component 7 includes two mounting cavities 71 symmetrically opened inside the collection box 6. The left and right ends of the two mounting cavities 71 respectively penetrate the left and right side walls of the collection box 6. Two limiting rods 72 are symmetrically and elastically inserted into the left and right pairs of the two mounting cavities 71. Two pairs of limiting holes are symmetrically opened on the adjacent sides of the two fixing frames 4. The two pairs of limiting rods 72 can be inserted into the two pairs of limiting holes respectively. The connecting component 7 also includes two pulling mechanisms 73 connected in the two mounting cavities 71. The two pulling mechanisms 73 are respectively connected to the adjacent ends of the two pairs of limiting rods 72 to pull the two pairs of limiting rods 72 in the direction of approach.

[0031] Specifically, by pulling the two pairs of limiting rods 72 towards each other through the pulling mechanism 73, the two pairs of limiting rods 72 can be pulled out from the two pairs of limiting holes. This allows the two fixed frames 4 to rotate around the hinge axis so that the top surfaces of the two filter screens 5 come close to each other. This allows the flocculated material trapped on the top surface of the filter screen 5 to slide down the filter screen 5 into the collection box 6. With a sufficiently large area of ​​filter screen 5, rapid separation of water and flocculated material can be achieved, effectively improving the flocculation treatment efficiency of chemical wastewater.

[0032] refer to Figures 1-5The pulling mechanism 73 includes two pairs of limiting plates 731 symmetrically fixedly connected in two mounting cavities 71, two pairs of limiting rods 72 symmetrically movably inserted into the two pairs of limiting plates 731, two baffles 732 symmetrically fixedly connected to the near ends of the two pairs of limiting rods 72, two pairs of elastic elements symmetrically fixedly connected between the two baffles 732 and the two limiting plates 731, two pairs of second pull ropes 733 symmetrically fixedly connected to the near sides of the two baffles 732, and two third pull ropes 734 symmetrically fixedly connected to the ends of the two pairs of second pull ropes 733 away from the baffles 732. The pulling mechanism 73 also includes two cylinders 735 symmetrically fixedly connected to the top of the top plate 1, the output ends of the two cylinders 735 penetrating the bottom surface of the top plate 1, and the top ends of the two third pull ropes 734 penetrating the top wall of the collection box 6 and respectively fixedly connected to the output ends of the two cylinders 735.

[0033] Specifically, the two cylinders 735 are activated to retract, and the two cylinders 735 pull the third pull rope 734 upward. The two third pull ropes 734 overcome the resistance of the two pairs of elastic elements through the two pairs of second pull ropes 733 and pull the two pairs of limit rods 72 toward each other. This allows the limit rods 72 to be quickly and reliably pulled out of the limit hole, realizing the separation between the two fixed frames 4 and the collection box 6, and ensuring that the ends of the two fixed frames 4 that are far apart can rotate upward to complete the collection of flocculated material.

[0034] refer to Figures 1-7 The two filter screens 5 are connected to the front and rear inner walls of the two fixed frames 4 by means of a first rotating rod and a first torsion spring. The two filter screens 5 are arranged in a figure-eight shape. The frame also includes two vibration components 8 symmetrically arranged on the inner walls of the two fixed frames 4. The two vibration components 8 are used to cooperate with the first rotating rod and the first torsion spring to drive the two filter screens 5 to vibrate back and forth.

[0035] Specifically, by vibrating the filter screen 5, the flocculated material on the top surface of the filter screen 5 can be more thoroughly slid into the collection box 6, preventing the flocculated material from adhering to the top surface of the filter screen 5 and clogging the filter holes, thus improving the reliability and practicality of the flocculator.

[0036] refer to Figure 3 , Figure 4 , Figure 6 and Figure 7The vibration assembly 8 includes two rectangular plates 81 symmetrically fixedly connected to the inner walls of two fixed frames 4 away from each other. Two sets of through cavities 82 are symmetrically opened on the side of the two rectangular plates 81 that are close to each other. The top and bottom ends of the through cavities 82 pass through the top and bottom surfaces of the rectangular plates 81, respectively. The vibration assembly 8 also includes two pairs of arc-shaped impact rods 83 symmetrically connected to the ends of two filter screens 5 away from each other. The circles corresponding to the two pairs of impact rods 83 coincide with the axis of the hinge shaft. The vibration assembly 8 also includes a drive mechanism 84 connected to the bottom of the top plate 1. The drive mechanism 84 is used to push the two pairs of first pull ropes 3 in the opposite direction.

[0037] The drive mechanism 84 includes two electric push rods 841 symmetrically fixedly connected to the bottom of the top plate 1. The output ends of the two electric push rods 841 are symmetrically fixedly connected to two rotating seats 842. Two guide rollers 843 are symmetrically rotatably connected to the two rotating seats 842. The two pairs of first pull ropes 3 can respectively press against the outer circumferential surface of the two guide rollers 843. When the two electric push rods 841 are activated to quickly reciprocate and extend, the two guide rollers 843 can be driven to quickly reciprocate and move towards each other, thereby pushing the two pairs of first pull ropes 3 to reciprocate and move closer or further away, thus causing the two sets of impact rods 83 to collide intermittently.

[0038] Specifically, the drive mechanism 84 is activated to push the two pairs of first pull ropes 3 in opposite directions, causing the ends of the two fixed frames 4 away from the hinge rod 61 to move back and forth, thus allowing the two pairs of impact rods 83 to collide intermittently. This, in conjunction with the first torsion spring and the first rotating rod, causes the ends of the two filter screens 5 away from the first rotating rod to collide with the rectangular plate 81, thereby causing the filter screens 5 to vibrate and ensuring that the flocculated material attached to the top surface of the filter screens 5 can smoothly and completely slide into the collection box 6.
