Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wastewater treatment, and particularly relates to a wastewater treatment equipment for resource recycling. BACKGROUND

[0002] Wastewater resourceization, also known as wastewater recycling, is a process of introducing industrial, agricultural and domestic wastewater into a predetermined purification system, and treating the wastewater by physical, chemical or biological methods so that the wastewater can meet the standard of reutilization.

[0003] Electrolytic flotation technology is a water treatment technology which uses micro-bubbles generated by electrolysis to adhere to impurity particles so that the impurity particles float to the water surface for easy removal. However, in the actual process of treating wastewater, the scum bubbles on the water surface may break due to external and internal factors, such as water flow impact, machine vibration, extrusion and collision during collection of the scum, and surface tension of the bubbles. After the bubbles break, some impurity particles originally adhered to the bubbles will sink. Since some air flotation machines are continuously supplied with water for treatment, wastewater continuously enters during the operation, and treated water continuously discharges, which may cause the sinking impurity particles to be discharged together with the water flow, thereby reducing the effect of wastewater treatment. SUMMARY

[0004] In order to overcome the shortcomings in the prior art that impurities may sink after the bubbles break and be discharged together with the water flow, the present application provides a wastewater treatment equipment for resource recycling, which can limit the sinking depth of impurities after the bubbles break during collection of the scum, and make the bubbles continue to float to the water surface after the collection of the scum is completed, and re-attach the sinking impurities with the floating bubbles, thereby improving the effect of wastewater treatment.

[0005] The technical scheme is as follows: a wastewater treatment equipment for resource recycling, comprising an electrolysis tank, a electrolysis partition plate fixedly connected in the electrolysis tank, an electrolysis cell fixedly connected between the electrolysis partition plate and the electrolysis tank, a water inlet pipe fixedly connected to the electrolysis tank in a communication mode, the water inlet pipe being located below the electrolysis cell, a scum collecting shell mounted on the electrolysis tank through a conveying mechanism, the conveying mechanism being used to drive the scum collecting shell to move so as to collect the scum floating on the water surface, a flow resistance frame fixedly connected in the electrolysis tank, the height of the flow resistance frame during wastewater treatment being lower than the water surface, a through hole for the bubbles to float to the water surface being formed in the flow resistance frame, and a partition plate rotatably connected in the through hole, the partition plate blocking the through hole of the flow resistance frame when the scum collecting shell collects the scum, so as to prevent the impurity particles from sinking, and the bubbles below the partition plate being able to continue to float after the partition plate is rotated and opened, so as to drive the sinking impurity particles to float to the water surface again by the bubbles.

[0006] As an improvement of the above scheme, the conveying mechanism is a chain conveyor, and the scum collecting shell is mounted on the chain of the chain conveyor.

[0007] As an improvement to the above scheme, it also includes a control mechanism for controlling the rotation of the partition plate according to the collection state of the scum. The control mechanism includes a pressure plate, which is slidably connected to the electrolysis tank. A spring is sleeved on the guide rod of the pressure plate. A slide is fixedly connected to the pressure plate, and a slide rail is opened on the slide rail. A hinge plate is fixedly connected to the partition plate, and a hinge shaft is fixedly connected to the hinge plate. The hinge shaft is located at the eccentric position of the hinge plate and is slidably connected in the slide rail opened on the slide rail, so as to control the rotation of the partition plate by raising and lowering the slide rail. A pressure rod for pushing the pressure plate downward is rotatably connected to the scum collection shell.

[0008] As an improvement to the above solution, a collection mechanism for collecting scum in the slag collection shell is also included. The collection mechanism includes a collecting pipe, which is fixed to the electrolysis tank. A rotating ring is rotatably connected to the collecting pipe. One end of a flexible hose is fixed to the rotating ring, and the flexible hose is connected to the inside of the collecting pipe through the rotating ring. The other end of the flexible hose is connected to the slag collection shell, so that the waste scum in the slag collection shell can flow into the collecting pipe through the flexible hose.

[0009] As an improvement to the above solution, a cleaning mechanism for cleaning the inside of the slag collection shell is also included. The cleaning mechanism includes a cleaning bracket, which is fixed to the electrolysis tank. A guide frame is slidably connected to the cleaning bracket. A second spring is sleeved on the guide rod of the guide frame. A guide frame is slidably connected to the guide frame. A scraper is slidably connected to the guide frame through a gathering guide rod. The scraper is used to push the floating slag inside the slag collection shell toward the hose. A third spring is sleeved on the gathering guide rod.

[0010] As an improvement to the above solution, the inside of the slag collection shell is W-shaped, so that the scraper can push the slag towards the connecting hose under the action of the inclined surface inside the slag collection shell.

[0011] As an improvement to the above solution, it also includes an articulated block and a torsion spring for connecting the slag collection shell and the chain conveyor. The articulated block is fixed to the chain of the chain conveyor, the articulated block and the slag collection shell are rotatably connected, and a torsion spring is connected between the slag collection shell and the articulated block.

[0012] As an improvement to the above solution, it also includes a fixed frame, an air pump, and a sealing shell for quickly introducing scum into the hose. The fixed frame is fixed to the guide frame, the air pump is fixed inside the fixed frame, and the air outlet of the air pump is fixed to a sealing shell for guiding the scum.

[0013] As an improvement to the above solution, it also includes a guide rail and a sliding shaft for guiding the guide frame. The guide rail is fixed to the cleaning bracket, the sliding shaft is fixed to the guide frame, and the sliding shaft and the guide rail are slidably connected.

[0014] As an improvement to the above solution, a filter membrane is also included, which is fixedly installed on the slag collection shell and can filter out scum from the water.

[0015] The present invention has the following advantages: 1. The device can automatically control the rotation of the partition plate according to the collection status of the slag collection shell. When collecting slag, the partition plate blocks the through holes on the flow-blocking frame, thereby limiting the sinking depth of impurities after the bubbles burst, thus preventing impurities from sinking and being discharged with the water flow. It also helps the bubbles to gather and merge into larger bubbles below the partition plate to increase buoyancy. After collecting the slag, the partition plate can automatically open, which allows the bubbles to continue to float to the water surface and allows the impurities on the partition plate to re-attach during the floating process, preventing the impurities from sinking and improving the wastewater treatment effect.

[0016] 2. In this equipment, when the chain conveyor drives the slag collection shell to move along a square track, the scraper can enter the slag collection shell and gather the floating slag collected by the slag collection shell towards the end of the hose. Then, the gathered floating slag is blown into the collection pipe by the jet pump, which realizes the cleaning and centralized collection of floating slag. This prevents floating slag from remaining in the slag collection shell and causing secondary pollution to the wastewater when collecting floating slag again, and further improves the wastewater treatment effect.

Detailed Implementation

[0025] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0026] Example 1: A wastewater treatment device for resource recovery, such as... Figures 1-3 As shown, the system includes an electrolysis tank 1, a conveying mechanism, a slag collection shell 102, a flow-blocking frame 103, a partition plate 104, an electrolysis partition 105, an electrolysis cell 106, an inlet pipe 107, and an outlet pipe 108. An electrolysis partition 105 is fixedly connected inside the electrolysis tank 1, dividing it into a left electrolysis zone and a right flotation zone. An electrolysis cell 106 is fixedly connected between the electrolysis partition 105 and the inner wall of the left side of the electrolysis tank 1. The electrolysis cell 106 is an electrolyte storage tank that uses current to decompose water molecules into hydrogen and oxygen in the prior art. During wastewater treatment, the height of the electrolysis partition 105 and the electrolysis cell 106 is lower than the water surface. An inlet pipe 107 for water intake is fixedly connected to the lower left side of the electrolysis tank 1, and the inlet pipe 107 is located below the electrolysis cell 106. The lower right side of the electrolysis tank 1 is connected to a water outlet pipe 108 for drainage. A slag collection shell 102 for collecting slag is installed on the electrolysis tank 1 via a conveying mechanism. The conveying mechanism is used to move the slag collection shell 102 to collect slag floating on the water surface. A flow-blocking frame 103 is fixedly connected to the front and rear side walls of the electrolysis tank 1. During the wastewater treatment process, the height of the flow-blocking frame 103 is also lower than the water surface so that the slag can float above the flow-blocking frame 103. The flow-blocking frame 103 has six elongated through holes, which are evenly distributed in the left and right direction. A partition plate 104 is rotatably connected in each through hole. The partition plate 104 is used to block the through holes on the flow-blocking frame 103 when the slag collection shell 102 collects slag to prevent impurity particles from sinking.

[0027] The conveying mechanism is a chain conveyor 101, which is a conveying device in the prior art. The slag collection shell 102 is installed on the chain of the chain conveyor 101.

[0028] When wastewater needs to be treated, it is transported into the electrolysis tank 1 through the inlet pipe 107. The flow rates of the inlet and outlet are controlled. Controlling the flow rate ensures that the water level is always higher than the flow-blocking frame 103 and the electrolysis baffle 105, and also prevents impurities from being directly carried away by the excessively fast flow rate. In the electrolysis zone, the wastewater first passes upward through the electrolysis cell 106 to generate oxygen and hydrogen bubbles, and then enters the flotation zone and flows towards the outlet pipe 108 on the right. Impurity particles in the wastewater adhere to the bubbles. Some bubbles will carry the impurities to the surface quickly under the action of buoyancy, while other bubbles will rise more slowly and move along an upward inclined trajectory under the influence of the water flow. For example, the size of the bubbles varies. Larger bubbles have greater buoyancy and are less affected by the water flow, so they rise faster. Smaller bubbles have less buoyancy and are more affected by the water flow, so they rise slower. Furthermore, the density of the impurity particles attached to the bubbles varies. Bubbles with lower density impurity particles rise faster, while those with higher density impurity particles rise faster. The bubbles in the particles rise slowly; the bubbles that rise faster float on the water surface above the flow-blocking frame 103, forming scum. After the chain conveyor 101 starts, it drives the scum collection shell 102 to rotate counterclockwise, and the movement trajectory of the scum collection shell 102 is square. When the scum collection shell 102 moves from left to right, it collects the scum that has already floated on the water surface. During the process of the scum collection shell 102 collecting scum, the baffle plate 104 is in a closed state, thereby limiting the sinking depth of impurity particles when the bubbles burst, and thus preventing impurities from sinking to a certain depth. Following the water flow, the water is discharged from the outlet pipe 108. Moreover, the obstruction of the partition plate 104 helps the slowly rising bubbles to gather and merge into larger bubbles below the partition plate 104, thereby increasing buoyancy. When the sludge collection shell 102 moves to the right and begins to move upward, the partition plate 104 will rotate and open. This allows the slowly rising bubbles to continue to float to the water surface, and also allows the slowly rising bubbles to reattach the impurity particles on the partition plate 104 during the floating process, thereby preventing the impurity particles from sinking and improving the wastewater treatment effect.

[0029] like Figures 2-4As shown, it also includes a control mechanism that controls the rotation of the partition plate 104 according to the scum collection state. The control mechanism is connected to the scum collection shell 102. The control mechanism includes a pressure plate 2, a first spring 201, a slide 202, a hinge plate 203, a pressure rod 204, and a hinge shaft 205. Pressure plates 2 are slidably connected to the front and rear side walls of the electrolysis tank 1 in the vertical direction. During wastewater treatment, the height of the pressure plate 2 is higher than the water surface, and the pressure plate 2 passes through the side wall of the electrolysis tank 1 and extends into the interior. A first spring 201 is sleeved on the guide rod of the pressure plate 2 to push it to return to its original position. A slide 202 is fixedly connected to the lower end of the pressure plate 2. The frame 202 has six equidistant straight tracks. The pivot of the partition plate 104 passes through the electrolysis tank 1 and extends outward. The outer end of the pivot of the partition plate 104 is fixedly connected to a hinge plate 203. The end of the hinge plate 203 away from the partition plate 104 is fixedly connected to a hinge shaft 205. The hinge shaft 205 is located at the eccentric position of the hinge plate 203. The hinge shaft 205 is slidably connected in the straight track on the slide frame 202 so as to control the rotation of the partition plate 104 by the lifting and lowering of the slide frame 202. Two pressure rods 204 are symmetrically rotatably connected on the side wall of the slag collection shell 102. The pressure rods 204 are used to push the pressure plate 2 downward.

[0030] When the slag collection shell 102 moves to the left side of the chain conveyor 101, and the slag collection shell 102 changes from vertical downward movement to horizontal rightward movement, the pressure rod 204 will push the pressure plate 2 downward, and the first spring 201 will be compressed, causing the pressure plate 2 to drive the slide 202 to move downward, so as to drive the partition plate 104 to rotate and close through the slide rail and hinge shaft 205 on the slide 202; when the slag collection shell 102 moves to the right side of the chain conveyor 101, and the slag collection shell 102 changes from horizontal movement to vertical upward movement, the pressure rod 204 will disengage from the pressure plate 2, and the first spring 201 will push the pressure plate 2 upward to reset, thereby causing the partition plate 104 to rotate and open.

[0031] Example 2: Based on Example 1, such as Figure 1 , Figure 2 and Figure 4 As shown, it also includes a collection mechanism for collecting scum in the scum collection shell 102. The collection mechanism is connected to the scum collection shell 102 and includes a collection pipe 3, a hose 301, and a rotating ring 302. The collection pipe 3 is fixedly connected to the electrolysis tank 1. The collection pipe 3 is a three-section pipe, which is connected together by two rotating rings 302. The hose 301 is fixedly connected to the rotating ring 302 and is connected to the inside of the collection pipe 3 through the rotating ring 302. One end of the scum collection shell 102 is open. The end of the hose 301 away from the rotating ring 302 is connected to the end of the scum collection shell 102 away from the open end, so that the waste in the scum collection shell 102 can flow into the collection pipe 3 through the hose 301. A one-way valve is installed in the hose 301 to prevent the scum from flowing back.

[0032] like Figure 1 , Figure 5 and Figure 6 As shown, it also includes a cleaning mechanism for cleaning the inside of the slag collection shell 102. The cleaning mechanism is installed on the electrolysis tank 1 and includes a cleaning bracket 4, a guide frame 401, a second spring 402, a guide frame 403, a gathering guide rod 404, a scraper 405, and a third spring 406. The cleaning bracket 4 is fixedly connected to the electrolysis tank 1, and the guide frame 401 is slidably connected to the cleaning bracket 4 in the horizontal direction. A second spring 402 is sleeved on the guide rod of the guide frame 401 to push it back to the right. A guide frame 403 is slidably connected to the frame 401 in the vertical direction. Two sets of gathering guide rods 404 are symmetrically fixed to the lower side of the guide frame 403. There are two gathering guide rods 404 in each set. Two scrapers 405 are symmetrically slidably connected to the gathering guide rods 404 in the horizontal direction. The scrapers 405 are used to push the scum in the scum collection shell 102 toward the hose 301. A No. 3 spring 406 is sleeved on each gathering guide rod 404, and the No. 3 spring 406 is located between the two scrapers 405 on the same gathering guide rod 404.

[0033] like Figure 7 As shown, the inside of the slag collection shell 102 is W-shaped, which allows the scraper 405 to push the slag towards the connecting hose 301 under the action of the inclined surface inside the slag collection shell 102.

[0034] like Figure 4 As shown, it also includes a hinge block 7 and a torsion spring 701 for connecting the slag collection shell 102 and the chain conveyor 101. The hinge block 7 is fixedly connected to the chain of the chain conveyor 101. The hinge block 7 is rotatably connected to the rotating shaft fixedly installed on the slag collection shell 102. The rotating shaft fixedly installed on the slag collection shell 102 is fitted with a torsion spring 701. One end of the torsion spring 701 is fixedly connected to the hinge block 7, and the other end of the torsion spring 701 is fixedly connected to the rotating shaft fixedly installed on the slag collection shell 102.

[0035] As the slag collecting shell 102 moves to the right side of the chain conveyor 101 and begins to move vertically upward, it gradually approaches the scraper 405. The scraper 405 gradually enters the slag collecting shell 102, and the scraper 405 comes into contact with the inner wall of the slag collecting shell 102. Because the interior of the slag collecting shell 102 is W-shaped, as the slag collecting shell 102 continues to move upward, the two scrapers 405 on the same converging guide rod 404 will move relative to each other under the action of the inclined plane. Spring 406 is compressed, which pushes the scum adhering to the inner wall of the scum collection shell 102 to the end of the hose 301 through scraper 405. This allows the scum to enter the collection pipe 3 through the hose 301, preventing scum residue in the scum collection shell 102 from causing secondary pollution to the wastewater during subsequent scum collection. When the scum collection shell 102 changes from vertical upward movement to horizontal leftward movement, since scraper 405 cannot rotate, the scum collection shell 102 and hinge block 7 will rotate clockwise, and torsion spring 70... 1. The energy is stored. When the slag collecting shell 102 begins to move horizontally, the hinge block 7 has already rotated 90 degrees clockwise. The scraper 405 is still located inside the slag collecting shell 102. By rotating the hinge block 7 and the chain conveyor 101, it is possible to prevent the slag collecting shell 102 from jamming with the scraper 405 during the direction change. Then, the slag collecting shell 102, through the scraper 405, first drives the guide frame 403 and the guide bracket 401 to move horizontally to the left. The second spring 402 will be compressed. Due to the certain adhesiveness of the slag, it is kept... The horizontal movement over a period of time allows sufficient time for the scum to enter the hose 301. Then, the guide frame 401 first drives the scraper 405 upward to disengage from the scum collection shell 102. After the scraper 405 disengages from the scum collection shell 102, the second spring 402 will push the guide frame 401 to reset to the right. The two scrapers 405 on the same gathering guide rod 404 will move in opposite directions under the action of the third spring 406, and the torsion spring 701 will drive the hinge block 7 and the scum collection shell 102 to rotate counterclockwise to reset.

[0036] Example 3: Based on Example 2, such as Figure 5 and Figure 6 As shown, it also includes a fixed frame 5 for quickly allowing scum to enter the hose 301, an air pump 501, and a sealing shell 502. Two fixed frames 5 are symmetrically fixed to the lower side of the guide frame 403. An air pump 501 is fixed inside the fixed frame 5. The air pump 501 is an air pump that can spray high-pressure gas in the prior art. The air outlet end of the air pump 501 is fixed to the sealing shell 502. The sealing shell 502 is used to guide the scum so that the scum can enter the hose 301.

[0037] When the slag collection shell 102 begins to move horizontally to the left, the scraper 405 has moved to the bottom along the inclined surface inside the slag collection shell 102. The lower end of the sealing shell 502 is in contact with the bottom inside the slag collection shell 102, and the sealing shell 502 is located between the two scrapers 405. The slag is gathered by the scrapers 405 to the bottom of the sealing shell 502. Then the jet pump 501 is started to spray air, thereby blowing the slag gathered to the bottom of the sealing shell 502 into the collection pipe 3.

[0038] like Figure 1 and Figure 5 As shown, it also includes guide rails 407 and sliding shafts 408 for guiding the guide frame 403. Two guide rails 407 are symmetrically fixed on the cleaning bracket 4. The guide rails 407 are composed of two connected slides. The slide on the right side is horizontal, and the slide on the left side is tilted with the left side higher than the right side. Two sliding shafts 408 are symmetrically rotatably connected on the guide frame 403. The sliding shafts 408 are slidably connected in the guide rails 407 on the same side.

[0039] The guide rail 407 guides the sliding shaft 408, allowing the guide frame 403 to move horizontally for a distance before the guide frame 403 drives the scraper 405 upward away from the slag collection shell 102.

[0040] like Figure 7 As shown, it also includes a filter membrane 6 to facilitate the discharge of water from the slag collection shell 102. The side wall of the slag collection shell 102 is provided with a through hole, and the filter membrane 6 is fixedly installed in the through hole. The filter membrane 6 can filter out the floating slag from the water.

[0041] During the process of collecting scum in the scum collection shell 102, water can pass through the filter membrane 6.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
