Description

Technical Field

[0001] The invention belongs to the technical field of printing and dyeing wastewater purification, in particular to a particle flotation and sedimentation purification device for deep treatment of printing and dyeing wastewater. Background Art

[0002] The Basic Principle of Flotation Purification: Flotation is a water treatment method that uses the buoyancy of bubbles generated by dissolving air in wastewater to control the sedimentation of suspended particles. Pressurized oxygen or other gases are added to the wastewater to dissolve the bubbles, which then attach to suspended particles and grease particles, forming flocs. The buoyancy of these bubbles is then utilized to remove suspended matter. Flotation is primarily suitable for treating wastewater containing high concentrations of suspended particles, grease, and other impurities.

[0003] Patent publication number CN118359255A discloses a flotation purification device for dyeing wastewater, which relates to the technical field of purification devices. The device comprises a wastewater tank, wherein the bottom four corners of the wastewater tank are fixedly connected to footrests, handles are fixedly connected to the sides of the wastewater tank, an air inlet pipe is fixedly connected to the bottom of one side of the wastewater tank, and a drain pipe is fixedly connected to the bottom of the other side of the wastewater tank. The drain pipe is equipped with a valve. A vent pipe is provided inside the wastewater tank, one end of the vent pipe is fixedly connected to the air inlet pipe, and the surface of the vent pipe is provided with several groups of air outlet heads. A control panel is fixedly installed on one side of the wastewater tank, and a pair of side seats are fixedly connected to the sides of the wastewater tank. The present invention has a reasonable structure. The wastewater and air in the wastewater tank are thoroughly mixed by a stirring device, so that the air is attached to the suspended particulate matter. The froth floating on the surface of the wastewater is then salvaged by a salvaging component.

[0004] In the current existing technology, when the existing printing and dyeing wastewater is purified, in order to reduce the particulate impurities inside the wastewater, flocs for coagulation are injected into the wastewater. As the flocs continue to increase, the printing and dyeing wastewater mixed with chemicals will form larger clumps inside the wastewater, and these larger clumps will cause blockages in the pipeline during transportation.

[0017] The beneficial effects of the present invention are as follows: 1. The particle flotation sedimentation purification device for deep treatment of printing and dyeing wastewater described in the present invention injects printing and dyeing wastewater into the mixing drum, and transports the water pollution control agent inside the control agent delivery box through the control agent infusion cylinder. At this time, the rotating sealing cylinder on one end of the control agent infusion cylinder is used to inject the water pollution control agent into the interior of the hollow roller. At this time, the hollow roller is rotated by the second motor, and the stirring arm on the outer surface of the hollow roller is used to stir the inside of the mixing drum. When the stirring arm stirs, the atomizing drainage grid plate on the outer surface of the stirring arm is used to spray the water pollution control agent inside the hollow roller out, so that the water pollution control agent and the printing and dyeing wastewater are repeatedly mixed. At the same time, the stirring of the stirring arm is used to sediment the impurity particles inside the printing and dyeing wastewater and achieve the effect of prevention and treatment. 2. The particle flotation sedimentation purification device for advanced treatment of printing and dyeing wastewater described in the present invention cooperates with a drain pipe to pump the settled sewage together with the small flocs into the interior of a uniform drainage tube. As the printing and dyeing wastewater continuously flows into the uniform drainage tube and the interior of the soft filter bag, some of the printing and dyeing wastewater falls under its own gravity and leaks from the surface of the soft filter bag, and some small flocs and printing and dyeing wastewater remain in the soft filter bag. At this time, the hydraulic rod is used to press down the lower pressure plate, and the space inside the soft filter bag and the uniform drainage tube is compressed. The excess gas will leak out from the surface of the soft filter bag very quickly. Since the bottom end of the soft filter bag is blocked by the small flocs, the gas will be squeezed out together with the printing and dyeing wastewater remaining in the small flocs. 3. The particle flotation sedimentation purification device for deep treatment of printing and dyeing wastewater described in the present invention is configured such that, under the downward pressure of the lower pressure plate, the wastewater inside the soft filter bag will be squeezed and discharged. As the number of squeezes increases, small clusters of flocs inside the soft filter bag continue to accumulate, and the motor drives the track teeth and the limit slider to automatically rotate on the inner wall surface of the limit track bar. When the limit slider rotates around the soft filter bag, the squeezing disk on the outer surface of the limit slider squeezes the surface of the soft filter bag. During the squeezing, the small clusters of flocs inside the soft filter bag will be repeatedly pushed, thereby changing the position of the small clusters of flocs and squeezing the small clusters of flocs, thereby effectively squeezing out some wastewater. 4. In the particle flotation and sedimentation purification device for deep treatment of printing and dyeing wastewater described in the present invention, wastewater leaking from the soft tube filter bag is pumped into the interior of the sterilization box. As the wastewater continues to accumulate inside the sterilization box, the printing and dyeing wastewater is separated in cooperation with the acrylic tube plate. At the same time, the acrylic tube plate is used to increase the contact area and range between the printing and dyeing wastewater and the acrylic tube plate. At this time, an ultraviolet searchlight is used to illuminate the interior of the acrylic tube plate. The transmittance of the acrylic tube plate is used to allow the ultraviolet light to completely irradiate the interior of the printing and dyeing wastewater. Due to the narrow gap between the two acrylic tube plates, the ultraviolet light can penetrate the printing and dyeing wastewater with a high degree of penetration, and the ultraviolet light can use the efficient bactericidal property to kill microorganisms inside the printing and dyeing wastewater.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1 to 2 and Figure 5-Figure 6 As shown, a particle flotation sedimentation purification device for deep treatment of printing and dyeing wastewater according to an embodiment of the present invention comprises a filtering and differentiation box 11 and a support frame 13 fixedly mounted on the top outer surface of the filtering and differentiation box 11, a prevention and control agent delivery box 1310 is fixedly mounted on the top surface of the filtering and differentiation box 11, a prevention and control agent infusion cylinder 139 is fixedly connected to the output end of the prevention and control agent delivery box 1310, a stirring drum 131 is fixedly mounted on the top outer surface of the support frame 13, and a support frame 2 133 is fixedly mounted on the top surface of the filtering and differentiation box 11 and on the edge of one side of the stirring drum 131. A second motor 134 is provided on the top surface of the second support frame 133, and a hollow roller 135 movably sleeved on the inner wall of the mixing drum 131 is fixedly connected to the output end of the second motor 134. The other end of the hollow roller 135 extends to the outer surface of the mixing drum 131, and a stirring arm 136 is fixedly connected to the outer surface of the hollow roller 135. The outer surface of the stirring arm 136 is provided with an atomizing drainage grid plate 137 connected to the hollow roller 135, and the other end of the hollow roller 135 is movably sleeved with a rotating sealing cylinder 138 fixedly connected to one end of the prevention and control agent infusion cylinder 139.

[0023] The interior of the mixing drum 131 is infused with printing and dyeing wastewater, and the water pollution control agent inside the control agent delivery box 1310 is transported through the control agent infusion cylinder 139. At this time, the rotating sealing cylinder 138 on one end of the control agent infusion cylinder 139 is used to infuse the water pollution control agent into the interior of the hollow roller 135. At this time, the hollow roller 135 is rotated in cooperation with the motor 2 134, and the stirring arm 136 on the outer surface of the hollow roller 135 is used to stir the interior of the mixing drum 131. When the stirring arm 136 stirs, the atomizing drainage grid plate 137 on the outer surface of the stirring arm 136 is cooperated to spray the water pollution control agent inside the hollow roller 135 out, so that the water pollution control agent and the printing and dyeing wastewater are repeatedly mixed. At the same time, the stirring of the stirring arm 136 is used to settle the impurity particles inside the printing and dyeing wastewater and achieve the effect of prevention and treatment. As the water pollution control agent and the printing and dyeing wastewater are repeatedly mixed, the water pollution control agent will coagulate the particulate impurities inside the printing and dyeing wastewater, and then the printing and dyeing wastewater will be continuously stirred by the stirring arm 136. The flow of the water source can drain the printing and dyeing wastewater at the inner peripheral position of the stirring drum 131 to the middle position of the stirring drum 131, thereby increasing the mixing of the printing and dyeing wastewater and the water pollution control agent. At the same time, the continuous stirring of the stirring arm 136 can also differentiate the flocs that have been condensed into small clumps of flocs, which is convenient for the subsequent drainage and discharge of the small clumps of flocs, and greatly avoids the effect of small clumps of flocs causing pipe blockage during flow.

[0024] like Figures 1 to 4 and Figure 9 As shown, an overlapping limit groove 125 is provided on the bottom inner wall surface of the uniform drainage tube 12, and a hydraulic rod 121 is fixedly installed on one side surface of the uniform drainage tube 12, and a lower pressure plate 122 is fixedly connected to the output end of the hydraulic rod 121, and an arc-shaped sealing baffle 123 is fixedly connected to the top surface of the lower pressure plate 122, and the outer surfaces of the lower pressure plate 122 and the arc-shaped sealing baffle 123 are movably overlapped on the inner wall surface of the uniform drainage tube 12, and a one-way water inlet pipe 124 is fixedly connected to the one side surface of the uniform drainage tube 12 and located at the bottom edge position, and the uniform drainage tube 12 is fixedly installed on the top surface of the filtration and differentiation box 11, and a soft tube filter bag 118 is fixedly connected on the bottom surface of the uniform drainage tube 12, and the outer surface of the soft tube filter bag 118 is movably overlapped on the outer surface of the extrusion plate 115, and the outer surface of the soft tube filter bag 118 is movably overlapped between the cavity 112 and the inside of the filtration and differentiation box 11.

[0025] The settled sewage together with the small group of flocs are poured into the interior of the uniform drainage tube 12 in cooperation with the drain pipe 1311. As the printing and dyeing wastewater continues to flow into the uniform drainage tube 12 and the soft filter bag 118, some of the printing and dyeing wastewater falls under its own gravity and leaks from the surface of the soft filter bag 118. Some small groups of flocs and printing and dyeing wastewater remain in the soft filter bag 118. At this time, the hydraulic rod 121 is used to press the lower pressure plate 122 downward. The space inside the soft filter bag 118 and the uniform drainage tube 12 is compressed, and the excess gas will leak out from the surface of the soft filter bag 118 very quickly. Since the bottom end of the soft filter bag 118 is blocked by the small group of flocs, the gas will be squeezed out together with the printing and dyeing wastewater remaining in the small group of flocs. As the lower pressure plate 122 continues to descend, the arc-shaped sealing baffle 123 on the side surface of the lower pressure plate 122 will block the entrance of the one-way water inlet pipe 124, preventing small clumps of flocs inside the one-way water inlet pipe 124 from remaining on the top surface of the lower pressure plate 122, and preventing small clumps of flocs from being discharged when the lower pressure plate 122 is driven to rise by the hydraulic rod 121, causing pollution.

[0026] like Figures 1 to 4 and Figure 9 As shown, two sets of drainage pipes 1311 are symmetrically fixedly connected to the two side surfaces of the mixing drum 131, one end of one set of drainage pipes 1311 is fixed with a one-way water inlet pipe 124, the top surface of the mixing drum 131 is fixedly connected with an exhaust pipe 132, the top inner wall surface of the filter and differentiation box 11 is provided with a cavity 112, the bottom inner wall surface of the filter and differentiation box 11 is provided with a guide chute 111, the top inner wall surface of the cavity 112 is fixedly connected with a limited track bar 113, and the inner wall surface of the limited track bar 113 is fixedly connected to the inner wall surface of the filter and differentiation box 11. The upper movable sleeve is connected to the limit slider 114, and the bottom surface of the limit slider 114 is fixedly connected to the extrusion plate 115, and the outer surface of the limit slider 114 is fixedly connected to the pushing track teeth 116 that are movably overlapped on the bottom surface of the limit track bar 113. Two groups of motors 117 are fixedly installed on the top inner wall of the cavity 112. The two groups of motors 117 are symmetrically arranged at the edge positions on both sides of the limit track bar 113, and the output end surface of motor 117 is movably overlapped on the outer surface of the pushing track teeth 116.

[0027] Under the downward pressure of the lower pressure plate 122, the wastewater inside the soft filter bag 118 will be squeezed and discharged. As the number of squeezing times increases, the small clusters of flocs inside the soft filter bag 118 continue to accumulate, and the motor 117 drives the track teeth 116 and the limit slider 114 to automatically rotate on the inner wall surface of the limit track bar 113. When the limit slider 114 rotates around the soft filter bag 118, the squeezing disk 115 on the outer surface of the limit slider 114 will squeeze the surface of the soft filter bag 118. During squeezing, the small clusters of flocs inside the soft filter bag 118 will be pushed repeatedly, thereby changing the position of the small clusters of flocs and squeezing the small clusters of flocs, thereby effectively squeezing out some wastewater.

[0028] like Figure 1-Figure 2 and Figures 7 and 8 As shown, a sterilization box 14 is fixedly installed on one side surface of the filtration and differentiation box 11, and an acrylic cylindrical plate 141 is fixedly connected to the top inner wall of the sterilization box 14. A drain pipe 2 147 is fixedly connected to the one side surface of the sterilization box 14 and at the bottom edge position. A lap sleeve 143 is fixedly connected to the top surface of the sterilization box 14 and at the edge positions on both sides. A motor 3 144 is fixedly installed on the top inner wall of the lap sleeve 143. A threaded rod 145 is fixedly connected to the output end of the motor 3 144. A pull-out slider 146 is threadedly movably sleeved on the outer surface of the threaded rod 145. An ultraviolet searchlight 142 is fixedly connected to the bottom surface of the pull-out slider 146. The outer surface of the ultraviolet searchlight 142 is movably sleeved on the inner wall of the acrylic cylindrical plate 141.

[0029] Wastewater leaking from the soft filter bag 118 is pumped into the sterilization box 14. As the wastewater accumulates inside the sterilization box 14, the acrylic tube plate 141 is used to separate the printing and dyeing wastewater. At the same time, the acrylic tube plate 141 increases the contact area and range between the printing and dyeing wastewater and the acrylic tube plate 141. At this time, the ultraviolet searchlight 142 is used to illuminate the interior of the acrylic tube plate 141. The light transmittance of the acrylic tube plate 141 allows the ultraviolet light to fully irradiate the interior of the printing and dyeing wastewater. Due to the narrow gap between the two acrylic tube plates 141, the ultraviolet light can penetrate the printing and dyeing wastewater with great penetration, and the ultraviolet light can effectively kill the microorganisms in the printing and dyeing wastewater with its efficient sterilization effect. In conjunction with the water temperature of the printing and dyeing wastewater inside the sterilization box 14, the temperature on the surface of the acrylic tube plate 141 is absorbed to reduce the surface temperature of the acrylic tube plate 141. At the same time, the printing and dyeing wastewater after absorbing heat will gradually heat up, thereby killing some high-temperature resistant and heat-resistant bacteria. Whenever the wastewater inside the sterilization box 14 is sterilized, the threaded rod 145 is rotated in conjunction with the motor three 144, and the pull-out slider 146 is moved upward on the surface of the threaded rod 145 to extract the ultraviolet searchlight 142 from the inside of the acrylic tube plate 141, which is convenient for replacement and maintenance of the ultraviolet searchlight 142, and at the same time has the effect of cooling the residual heat inside the acrylic tube plate 141.

[0030] Working principle: printing and dyeing wastewater is infused into the interior of the mixing drum 131, and the water pollution control agent inside the control agent delivery box 1310 is transported through the control agent infusion cylinder 139. At this time, the rotating sealing cylinder 138 on one end of the control agent infusion cylinder 139 is used to infuse the water pollution control agent into the interior of the hollow roller 135. At this time, the hollow roller 135 is rotated in conjunction with the motor 2 134, and the stirring arm 136 on the outer surface of the hollow roller 135 is used to stir the interior of the mixing drum 131. When the stirring arm 136 stirs, the atomizing drainage grid plate 137 on the outer surface of the stirring arm 136 is cooperated to spray the water pollution control agent inside the hollow roller 135 out, so that the water pollution control agent and the printing and dyeing wastewater are repeatedly mixed. At the same time, the stirring of the stirring arm 136 is used to settle the impurity particles inside the printing and dyeing wastewater and achieve the effect of prevention and treatment. The settled sewage together with the small group of flocs are poured into the interior of the uniform drainage tube 12 in cooperation with the drain pipe 1311. As the printing and dyeing wastewater continues to flow into the uniform drainage tube 12 and the soft filter bag 118, some of the printing and dyeing wastewater falls under its own gravity and leaks from the surface of the soft filter bag 118. Some small groups of flocs and printing and dyeing wastewater remain in the soft filter bag 118. At this time, the hydraulic rod 121 is used to press the lower pressure plate 122 downward. The space inside the soft filter bag 118 and the uniform drainage tube 12 is compressed, and the excess gas will leak out from the surface of the soft filter bag 118 very quickly. Since the bottom end of the soft filter bag 118 is blocked by the small group of flocs, the gas will be squeezed out together with the printing and dyeing wastewater remaining in the small group of flocs. Under the downward pressure of the lower pressure plate 122, the wastewater inside the soft filter bag 118 will be squeezed and discharged. As the number of squeezing increases, the small clusters of flocs inside the soft filter bag 118 continue to accumulate, and the motor 117 drives the track teeth 116 and the limit slider 114 to automatically rotate on the inner wall surface of the limit track bar 113. When the limit slider 114 rotates around the soft filter bag 118, the squeezing disk 115 on the outer surface of the limit slider 114 will squeeze the surface of the soft filter bag 118. During the squeezing, the small clusters of flocs inside the soft filter bag 118 will be repeatedly pushed, thereby changing the position of the small clusters of flocs and squeezing the small clusters of flocs, thereby effectively squeezing out some wastewater. Wastewater leaking from the soft filter bag 118 is pumped into the sterilization box 14. As the wastewater continues to accumulate inside the sterilization box 14, the acrylic tube plate 141 is used to separate the printing and dyeing wastewater. At the same time, the acrylic tube plate 141 is used to increase the contact area and range between the printing and dyeing wastewater and the printing and dyeing wastewater. At this time, an ultraviolet searchlight 142 is used to illuminate the interior of the acrylic tube plate 141. The transmittance of the acrylic tube plate 141 allows the ultraviolet light to completely irradiate the interior of the printing and dyeing wastewater. Due to the narrow gap between the two acrylic tube plates 141, the ultraviolet light can penetrate the printing and dyeing wastewater with a high degree of penetration, and use the efficient bactericidal properties of ultraviolet light to kill microorganisms inside the printing and dyeing wastewater.
