Description

Technical Field

[0001] This invention relates to the field of industrial wastewater treatment technology, and in particular to an industrial wastewater recycling and reuse device and its process. Background Technology

[0002] Industrial wastewater, including production wastewater, industrial sewage, and cooling water, refers to the wastewater and waste liquid generated during industrial production processes. It contains industrial raw materials, intermediate products, by-products, and pollutants lost during production. Industrial wastewater is diverse and complex in composition. For example, wastewater from the electrolytic salt industry contains mercury; wastewater from the heavy metal smelting industry contains lead, cadmium, and other metals; wastewater from the electroplating industry contains cyanide and chromium, among other heavy metals; wastewater from the petroleum refining industry contains phenols; and wastewater from the pesticide manufacturing industry contains various pesticides. Because industrial wastewater often contains multiple toxic substances, it pollutes the environment and poses a significant threat to human health. Therefore, it is essential to develop comprehensive utilization methods to turn harm into benefit, and to implement appropriate purification measures based on the composition and concentration of pollutants in the wastewater before discharge.

[0003] For example, patent application number CN202411942104.4 discloses "an industrial wastewater treatment and recycling device", which includes a box body, the box body being arranged vertically; a multi-functional roller group, arranged inside the box body, dividing the box body into a dosing chamber and a sedimentation chamber, including several parallel multi-functional roller bodies, the multi-functional roller group including a sealed state and a through state, the multi-functional roller group being in the sealed state.

[0004] However, in the aforementioned devices, industrial wastewater often contains a large amount of iron filings. Directly adding chemicals to treat industrial wastewater can easily cause a large accumulation and blockage of these iron filings, and the iron filings cannot be recycled and reused, which is not conducive to reducing costs. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that in the prior art, industrial wastewater often contains a large amount of iron filings. Direct chemical treatment of industrial wastewater can easily cause large accumulations and blockages of iron filings, and the iron filings cannot be recycled and reused, which is not conducive to reducing costs. Therefore, this invention proposes an industrial wastewater recycling and reuse device and process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An industrial wastewater recycling and reuse device includes a recycling bin, wherein a partition is fixedly installed inside the upper side of the recycling bin; It is also equipped with a filtration mechanism for filtering industrial wastewater.

The filter plate is fixedly connected to the output shaft of the motor. A hydraulic cylinder is fixedly installed at the lower end of the motor. The lower end of the hydraulic cylinder is fixedly installed on the inner bottom of the recycling bin. A support plate is fixedly installed on the output shaft of the motor. A sealing plate is fixedly installed at the upper end of the support plate. A hydraulic cylinder is fixedly installed at the left end of the sealing plate. The left end of the hydraulic cylinder is fixedly connected to the support plate. It is also equipped with a reaction mechanism for treating the industrial wastewater at the bottom of the recycling bin. The reaction mechanism includes a coarse grinding box fixedly installed at the lower end of the support plate, and a fine grinding box fixedly installed at the lower end of the coarse grinding box.

[0007] Preferably, cleaning strips are movably installed through the filter grooves on the filter plate, and an arc-shaped plate is fixedly installed at one end of the cleaning strip near the middle of the filter plate.

[0008] Preferably, a spring is fixedly installed at the far ends of the arc-shaped plates, and a fixing plate is fixedly installed at the other end of the spring. The lower end of the fixing plate is fixedly installed on the filter plate, and a protective plate is fixedly installed at the close ends of the cleaning strips corresponding to the filter grooves. The protective plate is slidably installed on the fixing plate, and the lower end of the protective plate abuts and fits against the filter plate.

[0009] Preferably, the filter plate has a protrusion on the upper side of the middle part corresponding to the arc plate, a support frame is fixedly installed on the upper end of the protrusion, and the lower end of the support frame is fixedly installed on the recycling bin.

[0010] Preferably, a sweeping plate is provided on the lower side of the protrusion, a guide rod is fixedly installed on the upper end of the sweeping plate, a slider is slidably installed through the upper end of the guide rod, the slider is slidably installed through the protrusion, and a spring is sleeved on the outer side of the guide rod, with the upper and lower ends of the spring being fixedly connected to the slider and the sweeping plate respectively.

[0011] Preferably, magnetic rods are fixedly installed symmetrically on both sides of the upper end of the slider, and magnetic blocks are fixedly installed on the upper end of the filter plate corresponding to the magnetic rods.

[0012] Preferably, an electromagnet is provided on the upper side of the partition, a gear ring plate is fixedly installed on the upper end of the electromagnet, the upper end of the gear ring plate is rotatably installed on the support frame, a gear is meshed on the outer side of the gear ring plate, a second motor is provided on the upper end of the gear, the upper end of the second motor is fixedly connected to the support frame, and a collection box is slidably installed through the electromagnet on the left end of the recycling bin.

[0013] Preferably, a passive plate is slidably installed through the upper left side of the coarse grinding box, and an active plate is slidably installed inside the right side of the coarse grinding box corresponding to the passive plate. A spring is fixedly installed between the right end of the active plate and the coarse grinding box.

[0014] Preferably, an inclined block is fixedly installed on the right end of the active plate, and a fixing plate two is fixedly installed at equal intervals on the inner wall of the recycling bin corresponding to the inclined block.

[0015] Preferably, a guide plate is fixedly installed on the front side of the upper end of the active plate, and a second guide rod is slidably installed through the guide plate. The lower end of the second guide rod is fixedly connected to the passive plate. A grinding roller is provided inside the fine grinding box, and the grinding roller is rotatably connected to the guide plate.

[0016] The process for an industrial wastewater recycling and reuse device includes the following specific steps: Step 1: Pour the industrial wastewater into the recycling bin, where the filter plate will filter out the iron filings. Step 2: Industrial wastewater flows into the bottom of the recycling bin, where it is mixed and reacted again by the powder falling from the coarse and fine grinding boxes. Finally, the industrial wastewater is treated and discharged. Step 3: Start the motor to drive the support plate, hydraulic cylinder 2, sealing plate and filter plate to rotate. Under the action of centrifugal force, the iron filings on the filter plate are thrown onto the partition plate, which makes it easier to adsorb and recover the iron filings on the partition plate. Step 4: The cleaning strips set up remove the iron filings stuck in the filter tank on the filter plate, causing the iron filings to fall onto the partition plate, which facilitates the electromagnet to attract and recover the iron filings. Step 5: The sweeping plate helps to sweep the iron filings remaining in the middle of the filter plate to the edge of the filter plate, and then throw them onto the baffle plate by centrifugal force, thus avoiding the presence of dead corners in the filter plate due to centrifugal force.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, industrial wastewater is poured into a recycling bin. The filter plate facilitates the filtration of iron filings in the industrial wastewater. The industrial wastewater flows into the bottom of the recycling bin, where it is mixed and reacted again by the powder falling from the coarse and fine grinding boxes. Finally, the industrial wastewater is treated and discharged.

[0018] 2. In this invention, starting hydraulic cylinder two drives the sealing plate to move to the left, blocking the lower end of the filter plate. The sealing plate and the filter plate overlap. Starting hydraulic cylinder one drives motor one, support plate, hydraulic cylinder two, sealing plate and filter plate to rise, causing the filter plate to extend out of the partition. Starting motor one drives support plate, hydraulic cylinder two, sealing plate and filter plate to rotate. Under the action of centrifugal force, it is easy to throw the iron filings on the filter plate onto the partition. Then, motor two drives gear to rotate, gear drives gear ring plate to rotate, gear ring plate drives electromagnet to rotate, which is convenient for adsorbing and recycling the iron filings on the partition. Pushing the collection box to the underside of the electromagnet, the electromagnet is de-energized, and the iron filings on the electromagnet fall onto the collection box. This is beneficial for recycling and reusing the iron filings in the recycling bin. The operation is simple and convenient, and the recycling efficiency of iron filings is improved.

[0019] 3. In this invention, when the filter plate rises, the protrusions move between the arc-shaped plates. When the filter plate rotates, the protrusions press against the arc-shaped plates, causing the arc-shaped plates to move the cleaning strips and protective plates away from each other. The spring is adaptively compressed and stores force. The cleaning strips facilitate the removal of iron filings stuck in the filter grooves on the filter plate, causing the iron filings to fall onto the partition plate. This facilitates the electromagnet's adsorption and recovery of the iron filings, while also ensuring that the filter plate is not blocked by iron filings, improving the iron filings recovery efficiency, and not affecting the normal filtration of industrial wastewater.

[0020] 4. In this invention, when the filter plate rises, the lower end of the sweeping plate will abut against the filter plate. When the filter plate rotates, it will also drive the magnetic block to rotate. When the magnetic block rotates to the side close to the magnetic rod, it will generate a magnetic repulsive force on the magnetic rod, pushing the slider, guide rod and sweeping plate to slide left and right on the protrusion synchronously. The sweeping plate is designed to sweep the iron filings remaining in the middle of the filter plate to the edge of the filter plate, and then throw them onto the partition plate by centrifugal force. This avoids the situation where there are dead corners of centrifugal force on the filter plate, resulting in incomplete removal of iron filings, and ensures the recycling effect of iron filings.

[0021] 5. In this invention, when the support plate rotates, it also drives the coarse grinding box to rotate synchronously. The coarse grinding box drives the active plate and the inclined block to rotate synchronously. The inclined block will be intermittently blocked and squeezed by the fixed plate, so that the inclined block drives the active plate to slide in the coarse grinding box. In cooperation with the passive plate, it crushes the industrial wastewater reaction block in the coarse grinding box, which facilitates the subsequent full mixing and reaction with the industrial wastewater, thereby improving the treatment efficiency of industrial wastewater.

[0022] 6. In this invention, when the active plate moves to the left, it also drives the guide plate to move to the left synchronously. The guide plate drives the guide rod two to slide in the guide plate, which in turn drives the passive plate to move back and forth, improving the crushing quality of the drug blocks in the coarse crushing box. The crushed drug blocks in the coarse crushing box will fall into the fine crushing box below. When the guide plate moves to the left, it also drives the roller to roll in the fine crushing box, which facilitates the further crushing of the drug blocks in the fine crushing box, thereby ensuring that the drug blocks can be crushed into finer particles and improving the subsequent reaction quality of industrial wastewater.

A spring 19 is sleeved on the outer side of the guide rod 17, and the upper and lower ends of the spring 19 are respectively connected to the slider 18. Block 18 and sweeping plate 16 are fixedly connected. Magnetic rods 20 are fixedly installed symmetrically on the upper end of the slider 18. Magnetic blocks 21 are fixedly installed on the upper end of the filter plate 3 corresponding to the magnetic rods 20. An electromagnet 22 is provided on the upper side of the partition plate 2. A gear ring plate 23 is fixedly installed on the upper end of the electromagnet 22. The upper end of the gear ring plate 23 is rotatably installed on the support frame 15. A gear 24 meshes on the outer side of the gear ring plate 23. A second motor 25 is provided on the upper end of the gear 24. The upper end of the second motor 25 is fixedly connected to the support frame 15. A collection box 26 is slidably installed through the electromagnet 22 on the left end of the recycling bin 1. During operation, industrial wastewater is poured into the recycling bin 1. The filter plate 3 facilitates the filtration of iron filings from the wastewater. The wastewater flows into the bottom of the recycling bin 1, where it is further mixed with chemical powder falling from the coarse grinding box 27 and fine grinding box 35. Finally, the treated wastewater is discharged. Hydraulic cylinder 28 is activated, causing the sealing plate 7 to move to the left. The sealing plate 7 blocks the lower end of the filter plate 3, aligning with it. Hydraulic cylinder 15 is activated, causing motor 14, support plate 6, hydraulic cylinder 28, sealing plate 7, and filter plate 3 to rise, extending the filter plate 3 from the partition 2. Motor 4 drives the support plate 6, hydraulic cylinder 8, sealing plate 7, and filter plate 3 to rotate. Under the action of centrifugal force, the iron filings on the filter plate 3 are easily thrown onto the partition plate 2. Then, motor 25 drives gear 24 to rotate, gear 24 drives gear ring plate 23 to rotate, and gear ring plate 23 drives electromagnet 22 to rotate, which facilitates the adsorption and recovery of iron filings on the partition plate 2. This pushes the collection box 26 to the underside of electromagnet 22. When the electromagnet 22 is de-energized, the iron filings on the electromagnet 22 fall onto the collection box 26, which is beneficial for the recycling and reuse of iron filings in the recycling bin 1. The operation is simple and convenient. This improves the iron filings recovery efficiency. When the filter plate 3 rises, the protrusion 14 moves between the arc plates 10. When the filter plate 3 rotates, the protrusion 14 squeezes the arc plate 10. The arc plate 10 drives the cleaning bar 9 and the protective plate 13 to move away from each other. The spring 11 is adaptively squeezed and stores force. The cleaning bar 9 is designed to easily remove iron filings stuck in the filter groove on the filter plate 3, causing the iron filings to fall onto the partition plate 2. This facilitates the electromagnet 22 to adsorb and recover the iron filings, while also ensuring that the filter plate 3 is not blocked by iron filings, thus improving the iron filings recovery efficiency without affecting the normal operation of industrial wastewater. In the filtration process, when the filter plate 3 rises, the lower end of the sweeping plate 16 will come into contact with the filter plate 3. When the filter plate 3 rotates, it will also drive the magnetic block 21 to rotate. When the magnetic block 21 rotates to the side close to the magnetic rod 20, it will generate a magnetic repulsion force on the magnetic rod 20, pushing the slider 18, the guide rod 17 and the sweeping plate 16 to slide left and right on the protrusion 14 in sync. The sweeping plate 16 is designed to sweep the iron filings remaining in the middle of the filter plate 3 to the edge of the filter plate 3, and then throw them onto the partition plate 2 by centrifugal force. This avoids the situation where there are dead corners of centrifugal force on the filter plate 3, resulting in incomplete removal of iron filings, and ensures the recycling effect of iron filings.

[0027] As an embodiment of the present invention, a reaction mechanism for reacting and treating industrial wastewater at the bottom of the recycling bin 1 is also provided. The reaction mechanism includes a coarse crushing box 27 fixedly installed at the lower end of the support plate 6, a fine crushing box 35 fixedly installed at the lower end of the coarse crushing box 27, a passive plate 28 slidably installed through the upper left side of the coarse crushing box 27, an active plate 29 slidably installed in the inner right side of the coarse crushing box 27 corresponding to the passive plate 28, a spring 30 fixedly installed between the right end of the active plate 29 and the coarse crushing box 27, an inclined block 31 fixedly installed in the right end of the active plate 29, and a fixed plate 32 fixedly installed at equal intervals on the inner wall of the recycling bin 1 corresponding to the inclined block 31, a guide plate 33 fixedly installed on the front side of the upper end of the active plate 29, a guide rod 34 slidably installed through the guide plate 33, the lower end of the guide rod 34 fixedly connected to the passive plate 28, and a crushing roller 36 is provided inside the fine crushing box 35, the crushing roller 36 being rotatably connected to the guide plate 33. During operation, when the support plate 6 rotates, it also drives the coarse grinding box 27 to rotate synchronously. The coarse grinding box 27 drives the active plate 29 and the inclined block 31 to rotate synchronously. The inclined block 31 is intermittently blocked and squeezed by the fixed plate 32, causing the inclined block 31 to drive the active plate 29 to slide inside the coarse grinding box 27. In cooperation with the passive plate 28, it crushes the industrial wastewater reaction blocks inside the coarse grinding box 27, which facilitates the subsequent thorough mixing and reaction with the industrial wastewater, thus improving the treatment efficiency of the industrial wastewater. When the active plate 29 moves to the left, it also drives the guide plate. 33 moves synchronously to the left, and the guide plate 33 drives the guide rod 34 to slide in the guide plate 33, which in turn drives the passive plate 28 to reciprocate back and forth, improving the crushing quality of the drug blocks in the coarse crushing box 27. The crushed drug blocks in the coarse crushing box 27 will fall into the fine crushing box 35 below. When the guide plate 33 moves to the left, it will also drive the roller 36 to roll in the fine crushing box 35, which facilitates the further crushing of the drug blocks in the fine crushing box 35, thereby ensuring that the drug blocks can be crushed into finer particles and improving the subsequent reaction quality of industrial wastewater.

[0028] The process for an industrial wastewater recycling and reuse device includes the following specific steps: Step 1: Pour the industrial wastewater into the recycling bin 1, and the filter plate 3 will filter out the iron filings in the industrial wastewater. Step 2: Industrial wastewater flows into the bottom of the recycling bin 1, where it is mixed and reacted again by the powder falling from the coarse grinding box 27 and the fine grinding box 35. Finally, the industrial wastewater is treated and discharged. Step 3: Start motor 4 to drive support plate 6, hydraulic cylinder 8, sealing plate 7 and filter plate 3 to rotate. Under the action of centrifugal force, the iron filings on filter plate 3 are thrown onto partition plate 2, which makes it easier to adsorb and recover the iron filings on partition plate 2. Step 4: The cleaning strip 9 removes the iron filings stuck in the filter tank on the filter plate 3, causing the iron filings to fall onto the partition plate 2, which facilitates the electromagnet 22 to adsorb and recover the iron filings. Step 5: The sweeping plate 16 is designed to sweep the iron filings remaining in the middle of the filter plate 3 to the edge of the filter plate 3, and then throw them onto the partition plate 2 by centrifugal force, thus avoiding the presence of centrifugal dead zones on the filter plate 3.

[0029] Working principle: In use, industrial wastewater is poured into the recycling bin 1. The filter plate 3 facilitates the filtration of iron filings from the wastewater. The wastewater flows into the bottom of the recycling bin 1, where it is mixed again by the powder falling from the coarse grinding box 27 and the fine grinding box 35. Finally, the treated wastewater is discharged. Hydraulic cylinder 2 8 is activated, causing the sealing plate 7 to move to the left. The sealing plate 7 blocks the lower end of the filter plate 3, aligning with it. Hydraulic cylinder 5 is activated, causing motor 4, support plate 6, hydraulic cylinder 2 8, sealing plate 7, and filter plate 3 to rise, extending the filter plate 3 from the partition 2. Motor 4 is activated, causing support plate 6, hydraulic cylinder 2 8, sealing plate 7, and filter plate 3 to rotate. Under centrifugal force, the iron filings on the filter plate 3 are easily thrown onto the partition 2. Then, the motor 25 drives the gear 24 to rotate, the gear 24 drives the gear ring plate 23 to rotate, and the gear ring plate 23 drives the electromagnet 22 to rotate, which facilitates the adsorption and recycling of iron filings on the partition 2. This pushes the collection box 26 to move to the underside of the electromagnet 22. When the electromagnet 22 is de-energized, the iron filings on the electromagnet 22 fall onto the collection box 26, which is beneficial for the recycling and reuse of iron filings in the recycling bin 1. The operation is simple and convenient, and the recycling efficiency of iron filings is improved. When the filter plate 3 rises, the protrusion 14 will also move between the arc plate 10. When the filter plate 3 rotates, the protrusion 14 will squeeze the arc plate 10. The arc plate 10 will drive the cleaning bar 9 and the protective plate 13 to move away from each other. The spring 11 is adaptively squeezed and stored. The cleaning bar 9 is set to facilitate the cleaning of the filter plate. 3. The iron filings stuck in the filter tank are removed, causing them to fall onto the partition plate 2. This facilitates the adsorption and recovery of iron filings by the electromagnet 22, while also ensuring that the filter plate 3 is not clogged by iron filings, improving the recovery efficiency of iron filings without affecting the normal filtration of industrial wastewater. When the filter plate 3 rises, the lower end of the sweeping plate 16 will abut against the filter plate 3. When the filter plate 3 rotates, it will also drive the magnetic block 21 to rotate. When the magnetic block 21 rotates to the side close to the magnetic rod 20, it will generate a magnetic repulsive force on the magnetic rod 20, pushing the slider 18, guide rod 17 and sweeping plate 16 to slide left and right synchronously on the protrusion 14. The sweeping plate 16 is designed to sweep the iron filings remaining in the middle of the filter plate 3 to the edge of the filter plate 3, and then throw them onto the partition plate 2 by centrifugal force, avoiding the centrifugal force dead zone on the filter plate 3. The corners prevent incomplete removal of iron filings, ensuring effective iron filings recycling. When the support plate 6 rotates, it also drives the coarse grinding box 27 to rotate synchronously. The coarse grinding box 27 drives the active plate 29 and the inclined block 31 to rotate synchronously. The inclined block 31 is intermittently blocked and squeezed by the fixed plate 32, causing the inclined block 31 to drive the active plate 29 to slide within the coarse grinding box 27. In cooperation with the passive plate 28, the active plate 29 crushes the industrial wastewater reaction blocks within the coarse grinding box 27, facilitating thorough mixing and reaction with the industrial wastewater and improving the treatment efficiency of the industrial wastewater. When the active plate 29 moves to the left, it also drives the guide plate 33 to move synchronously to the left. The guide plate 33 drives the guide rod 34 to slide within the guide plate 33, thereby causing the passive plate 28 to reciprocate back and forth.The crushing quality of the drug blocks in the coarse crushing box 27 is improved. The crushed drug blocks in the coarse crushing box 27 fall into the fine crushing box 35 below. When the guide plate 33 moves to the left, it also drives the grinding roller 36 to roll in the fine crushing box 35, which facilitates further crushing of the drug blocks in the fine crushing box 35. This ensures that the drug blocks can be crushed into finer particles, thereby improving the subsequent reaction quality of industrial wastewater.
