Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a chlorinated polyethylene wastewater treatment device. Background Art

[0002] During the processing of chlorinated polyethylene, a large amount of acidic wastewater will be generated. These wastewaters cannot be effectively utilized, so the chlorinated polyethylene wastewater needs to be treated. Calcium chloride is a commonly used neutralizer that can neutralize the acidic substances in the acidic wastewater, thereby increasing the pH value of the solution and achieving the treatment of the acidic wastewater.

[0003] After investigation, it was found that most of the existing chlorinated polyethylene wastewater treatment equipment is a neutralization container. When chlorinated polyethylene wastewater needs to be treated, the chlorinated polyethylene wastewater needs to be injected into the neutralization container using a suction pump, and then a neutralizing agent such as calcium chloride is added to the neutralization container, and the solution in the neutralization container is stirred with a stirring component. During the neutralization treatment of the wastewater in the neutralization container, the treatment of other wastewater is suspended. After the wastewater in the neutralization container is treated, the treated wastewater in the neutralization container needs to be discharged before new wastewater can be treated. This makes the current chlorinated polyethylene wastewater treatment efficiency relatively low. Summary of the invention

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] like Figures 1 to 9 As shown, the present invention includes the following embodiments:

[0031] Embodiment 1: A chlorinated polyethylene wastewater treatment equipment comprises a tower body 1 and a bracket 11 fixedly connected to the bottom of the tower body 1; the center of the tower body 1 is fixedly connected to a center rod 2; the outer wall of the center rod 2 is in contact with the inner wall of the tower body 1 and is provided with a first spiral plate 3; the upper end of the first spiral plate 3 is connected to the output shaft of a motor 4; a water inlet joint 12 is provided at the upper position of the inner wall of the tower body 1; the outer wall of the center rod 2 is provided with a feed joint 21 aligned with the water inlet joint 12; a water outlet hole 13 is provided on the inner bottom wall of the tower body 1; the lower orifice of the water outlet hole 13 is fixedly connected to the water outlet joint 14; the bottom of the tower body 1 is fixedly connected to a material pump 15; the center rod 2 is fixedly connected to a feed hole 22; the upper end of the feed hole 22 is connected to the feed joint 21, and the lower end is connected to the material pump 15; the wastewater and the neutralizer are offset and flow in a spiral from top to bottom along the tower body 1; the first spiral plate 3 rotates in the opposite direction under the action of the motor 4 to inhibit the wastewater and the neutralizer from flowing downward.

[0032] The rotation of the motor 4 will drive the first spiral plate 3 to rotate, and the first spiral plate 3 will flow in the gap between the outer wall of the central rod 2 and the inner wall of the tower body 1. The rotation direction of the first spiral plate 3 is clockwise, and the acidic wastewater will enter the inner side of the tower body 1 along the water inlet joint 12. When wastewater enters the water inlet joint 12, the material pump 15 will work, and the material pump 15 will let the neutralizer enter the agent inlet joint 21 along the agent inlet hole 22, and the agent inlet joint 21 will spray the neutralizer out of the outer side of the central rod 2. Since the agent inlet joint 21 is aligned with the water inlet joint 12, the neutralizer sprayed from the agent inlet joint 21 is sprayed by the wastewater of the water inlet joint 12, and the mixed liquid formed by the wastewater and the neutralizer will spirally flow downward along the first spiral plate 3, and the mixed liquid will roll during the downward flow process to achieve full mixing of the wastewater and the neutralizer. The mixed liquid completes the neutralization reaction during the mixing process, and the transportation of the mixed liquid does not stop during the reaction process. Compared with the existing container static neutralization method, the wastewater treatment efficiency is improved;

[0033] The mixed liquid after neutralization will be discharged along the water outlet 13 of the inner bottom wall of the tower body 1, and new neutralizer and new wastewater will continuously enter between the outer wall of the center rod 2 and the inner wall of the tower body 1 to form a counter-flow. The motor 4 drives the rotation of the first spiral plate 3. The clockwise rotation of the first spiral plate 3 is equivalent to the rotation of the auger in the screw extruder. The clockwise rotation of the first spiral plate 3 will drive the mixed liquid under the tower body 1 to be transported upward, but the speed of the mixed liquid flowing from top to bottom is greater than the feeding speed of the first spiral plate 3. In this way, the rotation of the first spiral plate 3 can suppress the spiral flow speed of the mixed liquid, thereby prolonging the residence time of the mixed liquid between the inner wall of the tower body 1 and the outer wall of the center rod 2, and achieving full neutralization. In addition, the mixed liquid will be stirred during the rotation of the first spiral plate 3, so that the mixed liquid can be better mixed under stirring, thereby improving the neutralization effect.

[0034] Embodiment 2: The outer wall of the center rod 2 is in contact with the inner wall of the tower body 1 and is provided with a second spiral plate 5; the upper end of the second spiral plate 5 is connected to the output shaft of the motor 4; the second spiral plate 5 and the first spiral plate 3 are stacked on each other; the distance from the second spiral plate 5 to the bottom of the tower body 1 is less than the distance from the first spiral plate 3 to the bottom of the tower body 1; the lower surface of the first spiral plate 3 and the upper surface of the second spiral plate 5 form a spiral slag discharge channel 35; the upper surface of the first spiral plate 3 and the lower surface of the second spiral plate 5 form a spiral liquid inlet channel 53; the water inlet joint 12 and the agent inlet joint 21 are connected to the liquid inlet channel 53; the upper orifice of the water outlet hole 13 is fixedly connected to the filter screen 16; the upper end of the tower body 1 is an opening; the outer wall of the tower body 1 is fixedly connected to the top cover 6; the lower end of the top cover 6 is lower than the upper end of the tower body 1 in the vertical direction; the lower end of the top cover 6 is fixedly connected to the slag discharge joint 61; the upper ends of the first spiral plate 3 and the second spiral plate 5 protrude from the upper port of the tower body 1 and extend into the top cover 6.

[0035] The upper surface of the filter screen 16 is flush with the inner bottom wall of the tower body 1 ; a gap is formed between the lower end of the first spiral plate 3 and the inner bottom wall of the tower body 1 ; and the lower end of the second spiral plate 5 is in contact with the inner bottom wall of the tower body 1 .

[0036] The upper and lower surfaces of the second spiral plate 5 are penetrated with water-permeable holes 51 ; the water-permeable holes 51 have the filtering function of the filter net 16 .

[0037] After the wastewater entering the water inlet joint 12 and the neutralizing agent entering the agent inlet joint 21 are dispersed, they flow in a spiral from top to bottom along the liquid inlet channel 53. The neutralized mixture will be filtered by the filter screen 16 and discharged along the water outlet joint 14. The filter residue will be intercepted by the filter screen 16 and gathered at the bottom wall position of the tower body 1. As the motor 4 rotates, the first spiral plate 3 and the second spiral plate 5 will rotate in the gap between the outer wall of the center rod 2 and the inner wall of the tower body 1. The rotation of the first spiral plate 3 and the second spiral plate 5 will suppress the flow speed of the mixture in the liquid inlet channel 53 on the one hand, and drive the slag discharge channel 35 to move on the other hand. The lower end of the slag discharge channel 35 collects the filter residue gathered on the bottom wall of the tower body 1 during the rotation process, and the lower end of the second spiral plate 5 scrapes away the filter residue on the upper surface of the filter screen 16. The filter residue will enter the slag discharge channel 35 as the slag discharge channel 35 rotates. Under the rotation of the slag discharge channel 35, the filter residue will move from bottom to top along the spiral slag discharge channel 35.

[0038] The rotation of the liquid inlet channel 53 will make the mixture in the liquid inlet channel 53 flow from top to bottom at a slower speed. The slag discharge channel 35 is separated from the liquid inlet channel 53 by the first spiral plate 3 and the second spiral plate 5, so that the liquid flowing from top to bottom in the liquid inlet channel 53 does not affect the fluid flow in the slag discharge channel 35. In addition, the water permeable hole 51 can be added to be unidirectional, so that the liquid in the liquid inlet channel 53 cannot enter the slag discharge channel 35. Under the rotation of the slag discharge channel 35, the filter residue will be continuously collected by the slag discharge channel 35, and the liquid in the slag discharge channel 35 can flow back to the liquid inlet channel 53 through the water permeable hole 51, while the filter residue in the slag discharge channel 35 The slag will not pass through the water permeable hole 51, so that the filter residue in the slag discharge channel 35 will move up along the spiral slag discharge channel 35. When the filter residue in the slag discharge channel 35 moves up and is higher than the water inlet joint 12, the filter residue in the slag discharge channel 35 will continue to move up, and the rotating slag discharge channel 35 will drive the filter residue to continue to move up and exceed the upper port of the tower body 1. Finally, the filter residue in the slag discharge channel 35 is thrown out and falls into the top cover 6 under the action of centrifugation. The lower end of the top cover 6 can be tilted so that the filter residue inside the top cover 6 will gather and flow out along the slag discharge joint 61. The slag discharge joint 61 can be expanded according to the use requirements to avoid blockage.

[0039] In this embodiment, a through hole is provided at the top of the top cover 6 to ensure that the air pressure inside and outside the top cover 6 is stable;

[0040] This embodiment uses the rotating first spiral plate 3 and the second spiral plate 5 to suppress the flow rate of the mixture in the liquid inlet channel 53 on the one hand, and on the other hand can collect and discharge the filter residue on the bottom wall of the tower body 1, thereby realizing multi-stage treatment of wastewater and improving the treatment efficiency and effect of wastewater.

[0041] Embodiment 3: An annular track groove 23 is provided at the lower position of the outer wall of the center rod 2; the track groove 23 is obliquely provided on the outer wall of the center rod 2; the track groove 23 includes an upper limit position 231 and a lower limit position 232; the distance from the upper limit position 231 of the track groove 23 to the inner bottom wall of the tower body 1 is greater than the distance from the lower limit position 232 to the inner bottom wall of the tower body 1; a movable block 24 is movably connected in the track groove 23; the movable block 24 is fixedly connected to the first spiral plate 3 at the lower end.

[0042] The upper limit position 231 of the track groove 23 is arranged close to the water outlet 13 ; the lower end opening of the slag discharge channel 35 becomes larger when it is close to the water outlet 13 .

[0043] The lower surface of the first spiral plate 3 is hinged to the one-way plate 32 via a torsion spring 31; the materials in the slag discharge channel 35 can flow from bottom to top.

[0044] The first spiral plate 3 and the second spiral plate 5 will rotate around the central rod 2 during the rotation process, and the first spiral plate 3 will drive the movable block 24 to move along the track groove 23. The track groove 23 is inclined and has a drop difference between the upper limit position 231 and the lower limit position 232. In this way, the lower end of the first spiral plate 3 will move back and forth up and down under the movement of the movable block 24. The first spiral plate 3 that moves up and down will transmit the vibration force to the upper surface of the first spiral plate 3 to avoid impurities remaining on the first spiral plate 3, so that the upper surface of the first spiral plate 3 The impurities flow smoothly from top to bottom along with the fluid in the liquid inlet channel 53. When the lower end of the first spiral plate 3 moves upward, the opening of the lower end of the slag discharge channel 35 will be enlarged. When the lower end of the first spiral plate 3 moves downward, the opening of the lower end of the slag discharge channel 35 will be reduced. In this way, the volume of the slag discharge channel 35 changes back and forth, so that the filter residue in the slag discharge channel 35 is loosened, thereby avoiding accumulation and blockage, and the filter residue in the slag discharge channel 35 is easier to flow from bottom to top when loose, thereby improving the smoothness of the filter residue discharge in the wastewater treatment process;

[0045] In addition, since the upper limit position 231 of the track groove 23 is close to the water outlet 13, the opening of the lower end of the slag discharge channel 35 is the largest when it is close to the water outlet 13, and the opening of the lower end of the slag discharge channel 35 is the smallest when it is far from the water outlet 13, thus ensuring the collection effect of the filter residue around the filter screen 16 by the lower end of the slag discharge channel 35;

[0046] Finally, since the lower surface of the first spiral plate 3 is hinged to the one-way plate 32 by the torsion spring 31, the flow direction of the material and fluid in the slag discharge channel 35 is unidirectional. When the thickness of the slag discharge channel 35 becomes narrower, the material in the slag discharge channel 35 moves upward with the pressure of the fluid to open the one-way plate 32, and part of the fluid is discharged through the water permeable hole 51, so that the material can move stably upward under the action of the rotating slag discharge channel 35; the torsion spring 31 in this embodiment can be omitted.

[0047] Embodiment 4: The outer wall of the center rod 2 is provided with an inner annular groove 25; the bottom of the inner annular groove 25 is connected to the upper end of the feed hole 22; the inner annular groove 25 is rotatably sealed and connected to the inner annular sleeve 26; the feed joint 21 is connected to the inner annular sleeve 26 and connected to the inner annular groove 25; the inner wall of the tower body 1 is provided with an outer annular groove 17;

[0048] The bottom of the outer annular groove 17 is connected to the water inlet pipe 18; the water inlet pipe 18 extends to the outside; the inner rotating seal of the outer annular groove 17 is connected to the outer annular sleeve 19; the water inlet joint 12 is connected to the outer annular sleeve 19 and connected to the outer annular groove 17; the water inlet joint 12 and the agent inlet joint 21 are sleeved and connected to the perforated connecting pipe 7.

[0049] During the rotation of the first spiral plate 3 and the second spiral plate 5, the connecting pipe 7 will be driven to move, and the perforated connecting pipe 7 is connected to the liquid inlet channel 53. During the movement of the connecting pipe 7, the agent feed joint 21 and the inner annular sleeve 26 will be driven to rotate, and the inner annular sleeve 26 will rotate in the inner annular groove 25. During the movement of the connecting pipe 7, the water inlet joint 12 and the outer annular sleeve 19 will be driven to rotate, and the outer annular sleeve 19 will rotate in the outer annular groove 17. The material pump 15 will allow the neutralizer to enter the inner annular groove 25 along the agent feed hole 22, and finally be discharged to the connecting pipe 7 along the agent feed joint 21. The wastewater enters the outer annular groove 17 along the water inlet pipe 18, and finally enters the connecting pipe 7 along the water inlet joint 12, and the fluid in the connecting pipe 7 is directly discharged to the liquid inlet channel 53 along the hole. Therefore, no matter how the first spiral plate 3 and the second spiral plate 5 rotate, the wastewater and the neutralizer are always connected to the liquid inlet channel 53.

[0050] Embodiment 5: The motor 4 is fixedly connected to the outer top of the top cover 6; the output shaft of the motor 4 extends to the inner side of the top cover 6 and is fixedly connected to the electric push rod 8; the output end of the electric push rod 8 is fixedly connected to the connecting block 81; the connecting block 81 connects the first spiral plate 3 and the upper end of the second spiral plate 5.

[0051] For some difficult-to-treat wastewater, the number of turns of the first spiral plate 3 and the second spiral plate 5 entering the inner side of the tower body 1 is increased, that is, the electric push rod 8 is extended to drive the connecting block 81 to move downward, thereby extending the wastewater movement path and slowing down the wastewater flow slope. For some easy-to-treat wastewater, the number of turns of the first spiral plate 3 and the second spiral plate 5 entering the inner side of the tower body 1 is reduced, that is, the electric push rod 8 is shortened to drive the connecting block 81 to move upward, thereby shortening the wastewater movement path and increasing the wastewater flow slope, thereby ensuring the wastewater treatment effect and the wastewater treatment efficiency; the motor 4 will drive the electric push rod 8 and the connecting block 81 to rotate, thereby realizing the rotation of the first spiral plate 3 and the second spiral plate 5.
