Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a multi-stage separation purifier for industrial oily sewage. Background Art

[0002] Industrial oily wastewater refers to wastewater containing oily substances generated during the industrial production process. This type of wastewater usually comes from different types of industrial activities, such as petrochemical, mechanical processing, food processing, painting, electroplating and other industries. The industrial oily wastewater multi-stage separation purifier is a special treatment equipment for oil-water separation in oily wastewater.

[0003] Since the existing oily wastewater purification equipment cannot remove solid impurity particles in the water in time when separating oil and water from oily wastewater, it is very easy for solid impurities to get stuck in the pump body during subsequent use, affecting the normal progress of subsequent processes. The overall practical effect needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned problem and propose a multi-stage separation purifier for industrial oily wastewater. It improves the problem that the existing oily wastewater purification equipment cannot remove solid impurity particles in the water in time when separating oil and water from oily wastewater, which makes it very easy for solid impurities to get stuck in the pump body during subsequent use, affecting the normal progress of subsequent processes. The overall practical effect needs to be improved.

[0005] A multi-stage separation purifier for industrial oily wastewater comprises a support base, a debris removal tank and a separation tank: the top outer wall of the support base is provided with a debris removal tank, the side of the debris removal tank is provided with a separation tank, the side outer walls of the debris removal tank and the separation tank at the bottom are both provided with a support frame, and the bottom outer wall of the support frame is connected to the top outer wall of the support base, the interior of the debris removal tank is provided with a separation control mechanism, the interior of the separation tank is provided with an auxiliary separation mechanism, and the side of the auxiliary separation mechanism is provided with a filtering and debris removal mechanism;

[0006] The separation control mechanism includes a water pump, a first guide pipe, a second guide pipe and a limiting mesh plate. The water pump is installed on the inner wall of the bottom end of the impurity removal tank. The water outlet end of the water pump is docked with the first guide pipe. The side of the first guide pipe is docked with the second guide pipe through a flange, and the water outlet end of the second guide pipe is arranged inside the separation tank. The inner wall of the side of the separation tank is provided with a limiting mesh plate, and the limiting mesh plate is arranged as a porous filter structure.

[0007] Preferably, the auxiliary separation mechanism includes a drive motor, a transmission shaft and an auxiliary push plate. The drive motor is installed on the outer wall of the bottom end of the separation tank. The output end of the drive motor is connected to the outer wall of the bottom end of the transmission shaft. Auxiliary push plates are arranged at equal intervals outside the transmission shaft inside the separation tank.

[0008] Preferably, a single auxiliary push plate is configured as a strip-shaped plate structure.

[0009] Preferably, the filtering and impurity removal mechanism includes a filter cylinder, a sealing cover is installed above the impurity removal tank, and a feed pipe is installed on the top outer wall of the sealing cover. The impurity removal tank and the sealing cover are arranged to be detachable, and the filter cylinder is located inside the impurity removal tank.

[0010] Preferably, the filter cylinder is symmetrically provided with two groups of positioning blocks on the side outer wall at the top position, the impurity removal tank is provided with a support ring on the side inner wall near the top position, and the top outer wall of the support ring is correspondingly provided with two groups of positioning slots.

[0011] Preferably, the positioning block and the positioning slot are snap-fitted together, and a first threaded groove is formed through the outer wall of the top end of the positioning block.

[0012] Preferably, a second thread groove is correspondingly provided on the top outer wall of the support ring located at the positioning slot, and the first thread groove and the second thread groove are threadedly mounted with the fastening bolt.

[0013] The beneficial effects of the utility model are:

[0014] 1. When the industrial oily wastewater multi-stage separation purifier is in use, a filter cartridge is provided at the water inlet end of the device, so that the solid impurity particles in the water can be uniformly isolated and collected inside the filter cartridge before the oily wastewater enters the device for separation. In this way, the subsequent water pump will not be blocked by impurities and affect the subsequent separation process during operation. The filter cartridge is further set to a detachable design through the mechanism component, which is convenient for overall maintenance and cleaning, and has good practical effect.

[0015] 2. When the industrial oily wastewater multi-stage separation purifier is in use, a limiting mesh plate is set inside the separation tank. The design of increasing the flow resistance of the oily wastewater can reduce the flow rate of the oily wastewater, so that the oil droplets have more time to separate from the water, which helps to improve the oil-water separation effect. At the same time, the limiting mesh plate can prevent the oily wastewater from mixing again to a certain extent, ensuring that the separated oil and water remain at their respective levels. Further, a mechanism component is set at the bottom of the separation tank to increase the swirling force of the water flow, and then the rotation and flow speed of the water flow are increased to make the oil droplets in the oil-water mixture more active, thereby accelerating the process of their upward floating. At the same time, this method can increase the contact area between the oil droplets and water, promote the merging of the oil droplets, and thus improve the oil separation efficiency. The overall structural design is simple and the practical effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] When implementing: Figure 1-6 As shown, the multi-stage separation purifier for industrial oily wastewater includes a support base 1, a debris removal tank 2 and a separation tank 3: the top outer wall of the support base 1 is provided with the debris removal tank 2, the side of the debris removal tank 2 is provided with the separation tank 3, the side outer walls of the debris removal tank 2 and the separation tank 3 at the bottom are both provided with a support frame, and the bottom outer wall of the support frame is connected to the top outer wall of the support base 1, the interior of the debris removal tank 2 is provided with a separation control mechanism 4, the interior of the separation tank 3 is provided with an auxiliary separation mechanism 5, and the side of the auxiliary separation mechanism 5 is provided with a filtering and debris removal mechanism 6;

[0025] The separation control mechanism 4 includes a water pump 41, a first guide pipe 42, a second guide pipe 43 and a limiting mesh plate 44. The water pump 41 is installed on the inner wall of the bottom end of the impurity removal tank 2, and the water outlet end of the water pump 41 is docked with the first guide pipe 42. The side of the first guide pipe 42 is docked with the second guide pipe 43 through a flange, and the water outlet end of the second guide pipe 43 is arranged inside the separation tank 3. The inner wall of the side of the separation tank 3 is provided with a limiting mesh plate 44, and the limiting mesh plate 44 is set as a porous filter structure;

[0026] When it is necessary to transport the oily wastewater after preliminary filtration and impurity removal from the impurity removal tank 2 to the separation tank 3 for oil-water separation, it is only necessary to turn on the water pump 41. When the water pump 41 is turned on, the oily wastewater accumulated at the bottom of the impurity removal tank 2 will be automatically pumped into the first guide pipe 42, and then transported to the second guide pipe 43 through the drainage of the first guide pipe 42 and finally flow into the separation tank 3. Then, when the oily wastewater flows into the separation tank 3, it will first fall above the limiting mesh plate 44. Here, due to the setting of the limiting mesh plate 44, the flow rate of the oily wastewater can be reduced by increasing the flow resistance of the oily wastewater, so that the oil droplets have more time to separate from the water, which helps to improve the oil-water separation effect. At the same time, the limiting mesh plate 44 can prevent the oily wastewater from mixing again to a certain extent, ensuring that the separated oil and water remain at their respective levels. Figure 3 Two sets of pipes are symmetrically arranged on the side outer wall of the separation tank 3, and a control valve is provided on the outside of the pipe. When the oil and water need to be discharged separately, due to the different densities of oil and water, the oil will float above the water. At this time, the control valve outside the upper end of the pipe of the separation tank 3 is opened to discharge the oil, and the control valve outside the lower end of the pipe of the separation tank 3 is opened to discharge the water, thereby achieving the separation effect.

[0027] The auxiliary separation mechanism 5 includes a drive motor 51, a transmission shaft 52 and an auxiliary push plate 53. The drive motor 51 is installed on the outer wall of the bottom end of the separation tank 3, and the output end of the drive motor 51 is connected to the outer wall of the bottom end of the transmission shaft 52. Auxiliary push plates 53 are arranged at equal intervals outside the transmission shaft 52 inside the separation tank 3. When it is necessary to increase the swirling force of the water flow in order to accelerate the oil droplets in the oily wastewater to float above the water layer, it is only necessary to turn on the drive motor 51. When the drive motor 51 is turned on, it will automatically drive the transmission shaft 52 to rotate and then drive the auxiliary push plate 53 to rotate. As the auxiliary push plate 53 rotates, the flow speed of the oily wastewater can be accelerated, thereby increasing the rotation and flow speed of the water flow, making the oil droplets in the oil-water mixture more active, thereby accelerating their upward floating process. At the same time, this method can increase the contact area between the oil droplets and the water, promote the merging of the oil droplets, and thus improve the oil separation efficiency. It should be noted that the rotation speed of the auxiliary push plate 53 should not be too high, as long as it can drive the oily wastewater to generate a little swirling force, otherwise it will be counterproductive.

[0028] The single auxiliary push plate 53 is configured as a strip-shaped plate structure; through the above design, the auxiliary push plate 53 can better contact the oily wastewater.

[0029] The filter and impurity removal mechanism 6 includes a filter cartridge 61, a sealing cover is installed above the impurity removal tank 2, and a feed pipe is installed on the top outer wall of the sealing cover. The impurity removal tank 2 and the sealing cover are arranged to be detachable. The filter cartridge 61 is located inside the impurity removal tank 2, and the side outer wall of the filter cartridge 61 at the top position is symmetrically provided with two groups of positioning blocks 62. The side inner wall of the impurity removal tank 2 near the top position is provided with a support ring 63. The top outer wall of the support ring 63 is provided with two groups of positioning slots 64, and the positioning blocks 62 and the positioning slots 64 are engaged with each other. The top outer wall of the positioning block 62 is provided with a first threaded groove 65, and the top outer wall of the support ring 63 at the position of the positioning slot 64 is provided with a second threaded groove 66. The first threaded groove 65 and the second threaded groove 66 are threadedly installed with the fastening bolt 67; the arrangement of the filter cartridge 61 here enables the solid impurity particles inside the oily water to be automatically isolated and collected when the oily water enters the impurity removal tank 2. When the filter cartridge 61 is removed from the impurity removal tank 2 for the purpose of dumping the solid impurity particles therein, it is only necessary to completely unscrew the fastening bolt 67 from the inside of the first threaded groove 65, and then the positioning block 62 changes from the locked state to the active state, and then the filter cartridge 61 can be directly taken out from the interior of the impurity removal tank 2. When the cleaning is completed and the filter cartridge 61 is reinstalled, it is only necessary to adjust the filter cartridge 61 to the appropriate position and push the positioning block 62 on its side from top to bottom into the positioning slot 64 of the corresponding position. When the positioning block 62 moves to the bottom end of the positioning slot 64, the first threaded groove 65 and the second threaded groove 66 are in a corresponding fit state. Then, the fastening bolt 67 is directly used to pass through the first threaded groove 65 and screw it to the bottom end of the second threaded groove 66 to complete the installation.

[0030] Here, both the impurity removal tank 2 and the separation tank 3 are set as tank structures so that the equipment has excellent pressure-bearing and explosion-proof performance and can achieve self-control effect.

[0031] When the utility model is in use, the arrangement of the filter cylinder 61 here makes the solid impurity particles inside the oily water automatically isolated and collected inside the filter cylinder 61 when it enters the impurity removal tank 2, thereby protecting the water pump 41 described below;

[0032] When it is necessary to transport the oily wastewater after preliminary filtration and impurity removal from the impurity removal tank 2 to the separation tank 3 for oil-water separation, it is only necessary to turn on the water pump 41. When the water pump 41 is turned on, the oily wastewater accumulated at the bottom of the impurity removal tank 2 will be automatically pumped into the first guide pipe 42, and then transported to the second guide pipe 43 through the drainage of the first guide pipe 42 and finally flow into the separation tank 3. Then, when the oily wastewater flows into the separation tank 3, it will first fall above the limiting mesh plate 44. Here, due to the setting of the limiting mesh plate 44, the flow rate of the oily wastewater can be reduced by increasing the flow resistance of the oily wastewater, so that the oil droplets have more time to separate from the water, which helps to improve the oil-water separation effect. At the same time, the limiting mesh plate 44 can prevent the oily wastewater from mixing again to a certain extent, ensuring that the separated oil and water remain at their respective levels. Figure 3 Two sets of pipes are symmetrically arranged on the side outer wall of the separation tank 3, and a control valve is provided on the outside of the pipe. When the oil and water need to be discharged separately, due to the different densities of oil and water, the oil will float above the water. At this time, the control valve outside the upper end of the separation tank 3 can be opened to discharge the oil, and the control valve outside the lower end of the separation tank 3 can be opened to discharge the water, thereby achieving the separation effect;

[0033] When it is necessary to increase the swirling force of the water flow in order to accelerate the oil droplets in the oily wastewater to float above the water layer, it is only necessary to turn on the drive motor 51. When the drive motor 51 is turned on, it will automatically drive the transmission shaft 52 to rotate and then drive the auxiliary push plate 53 to rotate. As the auxiliary push plate 53 moves along its rotation trajectory, the flow speed of the oily wastewater can be accelerated, thereby increasing the rotation and flow speed of the water flow, making the oil droplets in the oil-water mixture more active, thereby accelerating the process of their upward floating. At the same time, this method can increase the contact area between the oil droplets and water, promote the merging of the oil droplets, and thus improve the oil separation efficiency. It should be noted that the rotation speed of the auxiliary push plate 53 should not be too high, as long as it can drive the oily wastewater to generate a little swirling force, otherwise it will be counterproductive.

[0034] It is noted here that the above-mentioned drive motor 51 can be powered by existing operating technology, whether it is powered by a power supply component or an external wire, which is a conventional operation and will not be described in detail here.

[0035] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
