Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a heavy metal PFET evaporation and concentration wastewater device. Background Technology

[0002] In PFET (Polymer Thin Film Evaporation Technology), wastewater is generated along with the production process. In order to reduce the harm to the environment and ensure that the discharged wastewater meets national standards, a wastewater purification process is often required before the wastewater is discharged. The wastewater purification equipment is adjusted accordingly depending on the type of wastewater and the production process.

[0003] Existing PFET evaporation and concentration wastewater treatment equipment often consists of multiple independent reaction vessels for oxidation, sterilization, and sedimentation of wastewater. Each reaction vessel is equipped with a single stirring rod to ensure uniform mixing of the purifying agent and wastewater. The purifying agent is often added manually, resulting in low efficiency and an inability to quickly and effectively treat wastewater. Furthermore, the equipment is difficult to operate, requiring precise control of the amount of purifying agent added by operators, which can easily lead to insufficient addition and unqualified wastewater treatment. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a heavy metal PFET evaporation and concentration wastewater device, which features automatic addition of wastewater treatment agent, effectively ensuring the mixing efficiency of the purifying agent and wastewater, and improving wastewater treatment efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heavy metal PFET evaporation and concentration wastewater device, comprising an outer support frame, wherein a mixing pipe and a filter pipe are fixedly installed on the inner side of the outer support frame, and at least three sets of the mixing pipe and filter pipe are provided, the mixing pipe and filter pipe being connected end to end, an inlet pipe being fixedly connected to the outer end of the mixing pipe, an outlet pipe being fixedly connected to the end of the filter pipe, a premixing chamber being fixedly connected to the inlet end of the mixing pipe, a feed pipe being fixedly connected to the top of the premixing chamber, and a storage roller being fixedly connected to the top of the feed pipe. Wastewater enters the mixing pipe from the inlet pipe and is sequentially purified within the three sets of mixing pipes.

[0006] Preferably, the mixing tubes are connected by a connecting tube, and the inlet end of the connecting tube is equipped with an electromagnetic control valve for controlling the closure of the liquid outlet of the mixing tube.

[0007] Preferably, a rotating blade is rotatably connected inside the premixing chamber, and a top block is threadedly connected to the tip of the rotating blade. A positioning sleeve is fixedly connected inside the feed pipe, and a push rod is movably connected inside the positioning sleeve. A return spring is provided between the push rod and the positioning sleeve. A top cone block is fixedly connected to the top of the push rod, and a lower push block is fixedly connected to the bottom of the push rod. When the rotating blade rotates, it drives the top block to rotate, and the top block pushes the lower push block. The lower push block pushes the top cone block upward through the push rod, thereby opening the discharge port inside the feed pipe to facilitate the purifying agent falling into the premixing chamber.

[0008] Preferably, the storage roller is used to store the purifying agent, the feed pipe and the storage roller are connected, the top cone block is used to block the feed pipe outlet, and the top cone block separates from the feed pipe outlet when it moves upward.

[0009] Preferably, the mixing tubes and storage rollers are matched one-to-one, with different mixing tubes connected end to end, and different storage rollers are used to store different purifying agents, adapting to different purification processes, and adding appropriate purifying agents for heavy metal PFET evaporation and concentration wastewater.

[0010] Preferably, a main shaft is rotatably connected inside the mixing tube, a stirring motor is installed outside the main shaft, and stirring blades are fixedly connected to the outside of the main shaft. An outer sleeve is fitted around the stirring blades, and the outer sleeve is fixedly connected to the inside of the mixing tube by a support rod. The rotation of the stirring blades driven by the main shaft ensures that the wastewater and the purifying agent can be fully mixed and reacted.

[0011] Preferably, the stirring blades are provided in three sets, with the stirring blades in the middle position and the stirring blades at both ends having opposite spiral directions, and the outer ring is provided with three sets matching the stirring blades.

[0012] Preferably, a helical rod is rotatably connected inside the mixing tube. The helical rod is located at the bottom inner side of the mixing tube. A drive wheel is fixedly connected to the main shaft extending to the outer side of the mixing tube. A driven wheel is fixedly connected to the end of the helical rod extending to the outer side of the mixing tube. A transmission belt is provided between the drive wheel and the driven wheel.

[0013] Preferably, the filter tubes are connected end to end, and different filter tubes are sequentially provided with filter screen, PP filter, and activated carbon filter.

[0014] Beneficial effects:

[0015] 1. This heavy metal PFET evaporation and concentration wastewater device uses a push rod to control the top cone block to disengage from the feed inlet inside the feed pipe, thereby opening the feed inlet and facilitating the entry of the purifying agent into the premixing chamber. Furthermore, the rotation speed of the rotating blades is positively correlated with the flow rate of the wastewater within the premixing chamber. When the rotating blades rotate faster, the frequency of adding purifying agent to the wastewater increases synchronously. Therefore, within the premixing chamber, the amount of purifying agent added is matched to the flow rate of the wastewater, achieving automatic control of the purifying agent dosage. This ensures the compatibility of wastewater and purifying agent content during the wastewater purification process, guaranteeing the effectiveness of wastewater purification and achieving automatic addition of the purifying agent, reducing operational difficulty and improving wastewater purification efficiency.

[0016] 2. This heavy metal PFET evaporation and concentration wastewater device, by setting up three sets of stirring blades, creates three water circulation flows inside the mixing tube. At the same time, the screw rod drives the water flow on the bottom side of the mixing tube from left to right, so that the circulating water flows of the three stirring blades are interconnected, thereby effectively ensuring the overall mixing effect of wastewater and purifying agent, ensuring that the wastewater can fully react with the purifying agent, and thus effectively ensuring the purification effect. At the same time, during drainage, the bottom screw rod can effectively prevent wastewater from remaining inside the mixing tube, improve drainage efficiency, and further improve the wastewater treatment efficiency.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1

[0026] Please see Figure 1-2 and Figure 5 A heavy metal PFET evaporation and concentration wastewater device includes an outer support frame 1. A mixing pipe 2 and a filter pipe 3 are fixedly installed on the inner side of the outer support frame 1. At least three sets of mixing pipe 2 and filter pipe 3 are provided. The mixing pipe 2 and filter pipe 3 are connected end to end. An inlet pipe 4 is fixedly connected to the outer end of the mixing pipe 2. An outlet pipe 5 is fixedly connected to the end of the filter pipe 3. A premixing chamber 6 is fixedly connected to the inlet end of the mixing pipe 2. A feed pipe 8 is fixedly connected to the top of the premixing chamber 6. A storage roller 7 is fixedly connected to the top of the feed pipe 8.

[0027] During the purification process, wastewater enters the mixing pipe 2 from the inlet pipe 4 and is purified sequentially inside the three sets of mixing pipes 2. When the wastewater enters the mixing pipe 2, the storage roller 7 adds the purifying agent into the premixing chamber 6 through the feed pipe 8. When the wastewater enters the interior of different mixing pipes 2, it must pass through the premixing chamber 6 and undergo preliminary mixing with the purifying agent inside the premixing chamber 6 before entering the matching mixing pipe 2.

[0028] The mixing pipes 2 are connected by connecting pipes, and an electromagnetic control valve is installed at the inlet end of the connecting pipe to control the closure of the outlet of the mixing pipe 2. This ensures that the wastewater reacts fully inside each mixing pipe 2 before entering the next treatment process.

[0029] The premixing chamber 6 is rotatably connected to a rotating blade 61. The top of the blade of the rotating blade 61 is threadedly connected to a top block 62. The feed pipe 8 is fixedly connected to a positioning sleeve 12. The positioning sleeve 12 is movably connected to a push rod 9. A return spring 13 is provided between the push rod 9 and the positioning sleeve 12. The top of the push rod 9 is fixedly connected to a top cone block 10. The bottom of the push rod 9 is fixedly connected to a lower push block 11.

[0030] The storage roller 7 is used to store the purifying agent. The feed pipe 8 is connected to the storage roller 7. The top cone block 10 is used to block the discharge port of the feed pipe 8. When the top cone block 10 moves upward, it separates from the discharge port of the feed pipe 8.

[0031] When wastewater is injected into the mixing pipe 2, the wastewater passes through the premixing chamber 6. During the flow of wastewater inside the premixing chamber 6, the wastewater drives the rotating blade 61 to rotate, the rotating blade 61 drives the top block 62 to rotate, the top block 62 pushes the lower push block 11, and the lower push block 11 pushes the top cone block 10 upward through the push rod 9. At the same time, the lower push block 11 compresses the reset spring 13, and the push rod 9 controls the top cone block 10 to disengage from the discharge port inside the feed pipe 8, thereby opening the discharge port inside the feed pipe 8, so that the purifying agent can fall into the premixing chamber 6. Furthermore, the rotation speed of the rotating blade 61 is positively correlated with the flow rate of wastewater inside the premixing chamber 6. When the rotating blade 61 rotates at a high speed, the frequency of adding purifying agent to the wastewater increases synchronously. Therefore, the amount of purifying agent added in the premixing chamber 6 is matched with the flow rate of wastewater, thereby achieving the effect of automatically controlling the amount of purifying agent added. This ensures the compatibility between the wastewater and purifying agent content during the wastewater purification process, thus guaranteeing the effectiveness of wastewater purification treatment. It also achieves the function of automatically adding wastewater treatment purifying agent, reducing the difficulty of operation, and improving the efficiency of wastewater purification.

[0032] The mixing tube 2 and the storage roller 7 are matched one-to-one, with different mixing tubes 2 connected end to end. Different storage rollers 7 are used to store different purifying agents, adapting to different purification processes. Suitable purifying agents are added for heavy metal PFET evaporation and concentration wastewater. These include at least oxidants, sterilizing agents, and precipitants.

[0033] The filter tubes 3 are connected end to end, and each filter tube 3 is sequentially equipped with a filter screen, a PP filter, and an activated carbon filter. After the wastewater passes through at least three sets of mixing tubes 2 for purification, the wastewater enters at least three sets of filter tubes 3 for filtration. It is filtered through the first filter screen filter tube 3 to filter the wastewater after sedimentation and reaction in the mixing tube 2, and then passes through subsequent filter tubes 3 before being discharged, ensuring the wastewater purification effect.

[0034] The filter tube 3 and the outer support frame 1 are fixedly connected by a threaded detachable connection, and the filter tube 3 can be installed and removed by a threaded connector.

[0035] Example 2

[0036] Please see Figure 1-6 Furthermore, based on Embodiment 1, a main shaft 21 is rotatably connected inside the mixing tube 2. A stirring motor 22 is installed outside the main shaft 21, and a stirring blade 23 is fixedly connected to the outside of the main shaft 21. An outer sleeve 24 is fitted around the outside of the stirring blade 23, and the outer sleeve 24 is fixedly connected to the inside of the mixing tube 2 by a support rod. The rotation of the stirring blade 23 driven by the main shaft 21 ensures that the wastewater and the purifying agent are fully mixed and reacted.

[0037] The stirring blades 23 are provided in three sets. The stirring blades 23 in the middle position are spiraled in opposite directions to the stirring blades 23 at both ends. The outer ring 24 is provided with three sets that match the stirring blades 23.

[0038] The mixing tube 2 is rotatably connected to a screw rod 25, which is located at the bottom of the inner side of the mixing tube 2. The main shaft 21 extends to the outer side of the mixing tube 2 and is fixedly connected to a drive wheel 26. The screw rod 25 extends to the outer end of the mixing tube 2 and is fixedly connected to a driven wheel 27. A transmission belt 28 is provided between the drive wheel 26 and the driven wheel 27.

[0039] refer to Figure 3-4 During the mixing reaction, the stirring motor 22 drives the main shaft 21 to rotate. The main shaft 21 drives the screw rod 25 to rotate through the driving wheel 26, the driven wheel 27 and the transmission belt 28. The main shaft 21 drives the three sets of stirring blades 23 to rotate. The three sets of stirring blades 23 cooperate with the screw rod 25 to make the purifying agent and wastewater fully mix and react.

[0040] refer to Figure 6 During the mixing process, the two side stirring blades 23 drive the water flow from the left end to the right end inside the outer ring 24. Therefore, the water flow inside the outer ring 24 is from left to right, and the water flow outside the outer ring 24 is from right to left. The middle stirring blade 23 is designed to be opposite to the two side stirring blades 23. So, the water flow inside the middle outer ring 24 is from right to left, and the water flow outside the middle outer ring 24 is from left to right. This creates three water circulation flows inside the mixing tube 2. At the same time, the screw rod 25 drives the water flow at the bottom inside the mixing tube 2 to flow from left to right. This makes the circulating water flows of the three stirring blades 23 interconnected, thus effectively ensuring the overall mixing effect of wastewater and purifying agent. This ensures that the wastewater can fully react with the purifying agent, thereby effectively ensuring the purification effect. At the same time, when draining, the bottom screw rod 25 can effectively prevent wastewater from remaining inside the mixing tube 2, improving drainage efficiency and further improving the wastewater treatment efficiency.
