Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of industrial wastewater treatment, and particularly relates to a device for treating oil-containing industrial wastewater. BACKGROUND

[0002] In the industrial production process, water treatment is generally carried out due to the process requirements, so that wastewater is generated in some production links. For example, water zones are used for cooling or flushing treatment in the production and processing processes of steel smelting and metal smelting. In these industrial production processes, oil may exist on the workpiece due to some lubricating treatment, and the oil may be mixed into the wastewater in some water treatment processes, so that separate treatment is required when the wastewater is treated.

[0003] A device for efficiently treating oil-containing industrial wastewater is disclosed in Chinese Patent No. CN116874142B, which comprises a dosing device, a stirring device and an oil scraping box. The dosing device adds flocculants and other reagents to the wastewater, and then the stirring device is used for stirring and mixing, so that the reagents fully react in the wastewater, and the oil contained in the wastewater is aggregated and floated to the liquid surface. Then the oil body floating is collected by the oil scraping box along the liquid surface.

[0004] The above-mentioned prior art solution has the following disadvantages: although the above-mentioned solution can scrape and collect oil from the liquid surface by the oil scraping box, it is necessary to rely on the reaction of reagents in the wastewater and the action of the air flotation device to make the oil in the wastewater aggregate and float, and then the oil scraping box can collect the floating oil along the liquid surface. The height position of the oil scraping box needs to be controlled, otherwise a large amount of wastewater will be collected together, resulting in insufficient separation of the wastewater and the oil, and further treatment is required, which leads to poor separation and recovery treatment effect of the oil in the wastewater. In addition, in the implementation process of the above-mentioned solution, the reagents need to be put into the wastewater first, and then the stirring device needs to be operated to stir and react the wastewater. After the reaction reaches a certain degree, the oil scraping box needs to be controlled to move to the corresponding position. The whole operation process is complicated and not convenient, and the treatment effect is not good. SUMMARY

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figures 1-7 As shown, an oily industrial wastewater treatment device includes a treatment cylinder 1 and a dosing device. The treatment cylinder 1 is equipped with a cylinder cover 3 at the top. An inlet pipe is provided on the back of the treatment cylinder 1 near the top, and an outlet pipe is provided on one side of the bottom of the treatment cylinder 1. Both the inlet and outlet pipes are equipped with valves with control switches to facilitate the control of wastewater inflow and outflow. The dosing device is installed on the cylinder cover 3 and is used to add flocculants or other agents that can polymerize oil into the wastewater in the treatment cylinder 1. The treatment device also includes an oil suction mechanism, a reciprocating motion mechanism, a lifting drive mechanism, and an oil recovery mechanism.

[0037] The oil absorption mechanism is arranged in the interior of the treatment cylinder 1, and comprises two extrusion plates 18 and an oil absorption felt 13. The two extrusion plates 18 are symmetrically arranged on both sides of the interior of the treatment cylinder 1, and are matched with the dosing device. The oil absorption felt 13 is connected between the two extrusion plates 18. The oil absorption felt 13 is made of polypropylene by melt blowing process. The polypropylene is a light material with strong oil absorption capacity and strong hydrophobicity, which facilitates the realization of the functions of absorbing oil and not absorbing water. The oil absorption felt 13 is wave-shaped, which facilitates bending and extrusion, and facilitates increasing the contact area with the sewage and improving the oil absorption efficiency.

[0038] The reciprocating mechanism comprises two inclined guide plates 12, two wave-shaped guide rails 6 and a telescopic rolling part. The two wave-shaped guide rails 6 are symmetrically and fixedly connected to the upper surface of the cylinder cover 3. The two inclined guide plates 12 are fixedly connected to the top of the corresponding wave-shaped guide rail 6. The telescopic rolling part is arranged between the two wave-shaped guide rails 6 and is matched with the extrusion plate 18.

[0039] The lifting driving mechanism is arranged on the cylinder cover 3 and is matched with the telescopic rolling part.

[0040] The oil body recovery mechanism is slidably arranged on the treatment cylinder 1 and is matched with the lifting driving mechanism.

[0041] The extrusion plate 18 is driven by the lifting driving mechanism to drive the wave-shaped oil absorption felt 13 to move up and down in the sewage. In this way, the oil absorption felt 13 can absorb the oil in the sewage. During the up-and-down movement of the oil absorption felt 13, the telescopic rolling part moves along the wave-shaped guide rail 6 to realize reciprocating linkage. During this process, the two extrusion plates 18 repeatedly move close to and separate from each other, so that the wave-shaped oil absorption felt 13 can stretch and contract during the up-and-down movement, thereby increasing the movement intensity and range of the oil absorption felt 13 and improving the absorption effect. During this process, the adjacent protruding positions of the oil absorption felt 13 are only close to each other and are not completely extruded together. When the telescopic rolling part is lifted to the position of the inclined guide plate 12 by the lifting driving mechanism, the oil body recovery mechanism slides to the position directly below the oil absorption felt 13. At this time, the telescopic rolling part continues to move upward along the inclined guide plate 12, and further contraction occurs due to the limiting and extruding effect of the inclined guide plate 12. In this way, the two extrusion plates 18 extrude and approach each other, so that the oil absorption felt 13 is completely flattened together, which facilitates the oil absorption felt 13 to absorb the oil and fall into the oil body recovery mechanism. When the lifting driving mechanism lowers the oil absorption felt 13 again, the oil absorption felt 13 is unfolded again, and the oil body recovery mechanism slides back to the position away from the oil absorption felt 13, so that the oil absorption felt 13 can be immersed in the sewage again to absorb oil. In this way, the oil in the sewage can be effectively separated.

[0042] In some specific embodiments, the lifting driving mechanism comprises a servo motor 10, a ball screw 7 and a screw sleeve 9, the top of the two inclined guide plates 12 are close to each other and are connected with a horizontal plate, the servo motor 10 is fixedly installed on the horizontal plate, the main shaft of the servo motor 10 is vertically downward, one end of the ball screw 7 is connected with the main shaft of the servo motor 10 through a shaft coupling, the other end is rotatably connected to the cylinder cover 3, the screw sleeve 9 is cooperatively connected to the ball screw 7, and the telescopic rolling element is cooperatively connected to the outer wall of the screw sleeve 9.

[0043] The telescopic rolling element comprises a roller 8, an elastic telescopic body and a linkage frame 17, the elastic telescopic body is provided with two groups and is symmetrically distributed on both sides of the screw sleeve 9, the roller 8 is provided with two groups, one end of each group of the elastic telescopic body away from the screw sleeve 9 is connected with the corresponding roller 8, and the roller 8 is matched with the corresponding wave-shaped guide rail 6, the strip-shaped opening 5 is provided on the cylinder cover 3 and is distributed with two groups, the linkage frame 17 is provided with two groups, and the two linkage frames 17 are cooperatively penetrated through the corresponding strip-shaped opening 5, and the linkage frame 17 is fixedly connected with the corresponding extrusion plate 18 at the bottom and is cooperatively connected with the corresponding elastic telescopic body at the top.

[0044] When the servo motor 10 drives the ball screw 7 to rotate forward, the linkage frame 17 is limited in the strip-shaped opening 5, and the linkage frame 17 is connected between the top and the screw sleeve 9 through the elastic telescopic element, so that the screw sleeve 9 cannot rotate synchronously with the ball screw 7 at this time, and can only move longitudinally downward, so that the linkage frame 17 drives the oil absorption felt 13 to descend synchronously and immerse into the sewage through the extrusion plate 18, and the roller 8 also descends synchronously. Figure 5 As shown in the figure, the roller 8 rolls from the recessed position to the protruding position of the wave-shaped guide rail 6 during the descending process, the elastic telescopic body is contracted due to extrusion in this process, and a rebound force is generated, and the extrusion plate 18 is horizontally moved through the corresponding linkage frame 17 during the contraction, that is, the two extrusion plates 18 on both sides are horizontally moved together, so that the wave-shaped oil absorption felt 13 is folded to a certain extent, and when the roller 8 rolls from the protruding position to the recessed position, the elastic telescopic body is reset and elongated by relying on the rebound force, that is, the two extrusion plates 18 on both sides are relatively separated, so that the oil absorption felt 13 is stretched and unfolded, so that the oil absorption felt 13 is repeatedly stretched and contracted when the roller 8 repeatedly passes through the recessed and protruding positions of the wave-shaped guide rail 6.

[0045] In some specific embodiments, as shown in the figure, Figure 3As shown, the two groups of elastic telescopic bodies each include a connecting sleeve 11, a telescopic slide rod 20 and a first spring 19, the telescopic slide rod 20 is slidably inserted into the connecting sleeve 11 at one end and connected with the corresponding roller 8 at the other end, the connecting sleeve 11 is connected with the lead screw sleeve 9 at the end away from the telescopic slide rod 20, the first spring 19 is connected between the telescopic slide rod 20 and the connecting sleeve 11, the first spring 19 is compressible, and the linkage frame 17 is fixedly connected to the top of the telescopic slide rod 20, so that the telescopic slide rod 20 can slide relative to the connecting sleeve 11 during the rolling of the roller 8 along the wavy guide rail 6.

[0046] In some specific embodiments, in order to ensure that the oil absorption felt 13 is below the oil body recovery mechanism to catch the oil when the oil is squeezed out, the oil body recovery mechanism can be specifically provided as follows: Figure 4 As shown, the oil body recovery mechanism includes a recovery sliding box 2, an elastic traction rope 28 and a fixed pulley 21, the recovery sliding box 2 is provided with two and penetrates through the front and rear sidewalls of the processing cylinder 1, the recovery sliding box 2 can slide transversely relative to the processing cylinder 1, the ends of the two recovery sliding boxes 2 between the processing cylinder 1 and the outer wall of the processing cylinder 1 are connected with a second spring 22 which is compressible, the elastic traction rope 28 is provided with two, one end of the two elastic traction ropes 28 is connected with the lead screw sleeve 9, and the other end is connected with the corresponding recovery sliding box 2, the elastic traction rope 28 can be stretched and deformed, and the fixed pulley 21 is provided with two and fixedly arranged on the front and rear sides of the cylinder cover 3, and the elastic traction rope 28 cooperates with the corresponding fixed pulley 21.

[0047] It should be noted that, Figure 4 The two recovery sliding boxes 2 are connected to the inside of the processing cylinder 1, and the second spring 22 is in a compressed state, if the lead screw sleeve 9 is lowered at this time, the two recovery sliding boxes 2 are separated by the elastic force of the corresponding second spring 22, and are offset away from the bottom of the oil absorption felt 13, so as to avoid affecting the oil absorption felt 13 to be immersed in the sewage, and after the lead screw sleeve 9 is lowered by a certain distance, the elastic traction rope 28 is completely relaxed and has no effect on the downward movement of the lead screw sleeve 9.

[0048] When the servo motor 10 drives the ball screw 7 to reverse, the screw sleeve 9 rises upward, and the roller 8 and the oil absorption felt 13 are synchronously lifted. When the oil absorption felt 13 is lifted to the corresponding position and is higher than the position of the recovery slide box 2, the roller 8 is lifted to the corresponding position and is close to the bottom of the inclined guide plate 12. At this time, the screw sleeve 9 continues to rise upward under the drive of the servo motor 10, and the screw sleeve 9 pulls the corresponding recovery slide box 2 to slide into the processing cylinder 1 under the pulling of the elastic traction rope 28. When the roller 8 contacts the bottom of the corresponding inclined guide plate 12, the two recovery slide boxes 2 are just connected together. In this process, the second spring 22 is compressed to generate a rebound force, and the elastic traction rope 28 does not stretch and deform. At this time, the roller 8 continues to rise with the screw sleeve 9, and then the roller 8 rolls upward along the inclined surface of the corresponding inclined guide plate 12. Since the elastic traction rope 28 can stretch and deform, the screw sleeve 9 can pull the elastic traction rope 28 to stretch and deform in this process, so that the screw sleeve 9 cannot further rise due to the position limitation of the recovery slide box 2. After the screw sleeve 9 further rises, as shown in Figure 6 , the roller 8 rolls to the top position of the inclined guide plate 12, and the linkage extrusion plate 18 extrudes the oil absorption felt 13, so that the oil in the oil absorption felt 13 is extruded out and falls into the recovery slide box 2, thereby achieving effective recovery.

[0049] In some specific embodiments, in order to facilitate the servo motor 10 to drive the oil absorption felt 13 to automatically move up and down, the specific arrangement can be as shown in Figure 6 and Figure 7 , the first travel switch 26 is installed on the top side wall of the inclined guide plate 12, and the second travel switch 27 is arranged near the bottom of the wave-shaped guide rail 6. The first travel switch 26 is electrically connected with the forward rotation control circuit of the servo motor 10, and the second travel switch 27 is electrically connected with the reverse rotation control circuit of the servo motor 10. When the main shaft of the servo motor 10 reversely drives the screw sleeve 9 to rise upward and drives the roller 8 to move to the top position of the inclined guide plate 12, the roller 8 acts on the first travel switch 26, and the first travel switch 26 feeds back a signal to make the motor controller control the main shaft of the servo motor 10 to rotate forward, so that the screw sleeve 9 descends. In this way, the roller 8 synchronously descends. When the roller 8 moves to the corresponding position at the bottom of the wave-shaped guide rail 6 and acts on the second travel switch 27, the second travel switch 27 feeds back a signal to make the motor controller control the main shaft of the servo motor 10 to rotate reversely, so that the screw sleeve 9 repeatedly moves up and down.

[0050] In some specific embodiments, in order to facilitate the oil absorption felt 13 to move up and down while synchronously adding chemicals into the sewage, so that the chemicals can be dispersed to different depths of the sewage, thereby facilitating sufficient reaction, the specific arrangement can be as shown in Figure 2As shown, the dosing device is provided with two groups, and is distributed on both sides of the barrel cover 3, and the two groups of dosing devices all include a storage tank 4, a connecting hose 15, a discharge pipe 23 and a telescopic spraying pipe; the storage tank 4 is fixedly arranged at the edge of the barrel cover 3, the storage tank 4 is used for storing flocculants, the discharge pipe 23 is fixedly arranged at one side of the bottom of the storage tank 4, the discharge pipe 23 penetrates through the barrel cover 3, the connecting hose 15 is connected at the bottom of the discharge pipe 23, and the two are in communication, and the telescopic spraying pipe is arranged at the bottom of the connecting hose 15, and the telescopic spraying pipe is further connected with the corresponding pressing plate 18.

[0051] Wherein, the telescopic spraying pipe includes a main sliding pipe 14 and a vice sliding pipe 25, one end of the vice sliding pipe 25 is fixedly connected with the corresponding pressing plate 18, the other end is slidably inserted into the main sliding pipe 14, a strip-shaped sliding groove 24 is longitudinally arranged on the inner wall of the processing barrel 1, and the end of the main sliding pipe 14 away from the vice sliding pipe 25 is slidably connected in the strip-shaped sliding groove 24. It should be noted that the end of the main sliding pipe 14 is limited in the strip-shaped sliding groove 24, and can only slide longitudinally, but cannot be separated horizontally. The end of the main sliding pipe 14 away from the vice sliding pipe 25 is also connected with the corresponding connecting hose 15, and the two are in communication.

[0052] When the two pressing plates 18 reciprocate horizontally, the vice sliding pipe 25 slides relative to the main sliding pipe 14, and when the pressing plate 18 lifts the oil absorbing felt 13, the main sliding pipe 14 slides longitudinally along the strip-shaped sliding groove 24, facilitating the longitudinal movement of the vice sliding pipe 25 with the pressing plate 18. During this process, the connecting hose 15 keeps the discharge pipe 23 and the main sliding pipe 14 in communication, so that the flocculants in the storage tank 4 can be discharged from the discharge pipe 23, then flow to the main sliding pipe 14 along the connecting hose 15, and finally be sprayed from the vice sliding pipe 25. Since the vice sliding pipe 25 moves up and down synchronously with the pressing plate 18, the flocculants can be dispersed and mixed to different depths of the sewage, facilitating effective reaction and promoting the rapid aggregation and floating of oil in the sewage.

[0053] Wherein, the discharge pipe 23 is provided with an electromagnetic valve 16, and the control switch of the electromagnetic valve 16 can be arranged at a corresponding position convenient for operation according to needs. The discharge pipe 23 is controlled by the electromagnetic valve 16, so as to control the discharge of the medicament in the storage tank 4.

[0054] Wherein, the connecting hose 15 is a corrugated flexible hose, which is convenient for stretching and contraction, thereby facilitating the up and down movement of the main sliding pipe 14.

[0055] In order to facilitate the personnel in the art to understand the embodiment of the present scheme, the working principle of the present scheme will be briefly described in combination with specific application scenarios:

[0056] Firstly, a certain amount of sewage is introduced into the treatment cylinder 1, and the sewage level is ensured to be lower than the position of the recovery slide box 2, and the flocculating agent or the related liquid for oil liquid polymerization is stored in the storage tank 4 in advance, and then the servo motor 10 is started;

[0057] The servo motor 10 first drives the ball screw 7 to rotate forward. Since the linkage frame 17 is limited in the strip-shaped opening 5, and the linkage frame 17 is connected with the screw sleeve 9 at the top, the screw sleeve 9 cannot rotate synchronously with the ball screw 7 at this time, and can only move downward longitudinally. Therefore, the linkage frame 17 drives the oil absorption felt 13 to descend synchronously by the extrusion plate 18 and immerse into the sewage, and the roller 8 also descends synchronously. During the descending process of the roller 8, the roller 8 rolls from the recessed position to the protruding position of the wave-shaped guide rail 6. During this process, the telescopic slide rod 20 is contracted relative to the connecting sleeve 11 due to extrusion, and the first spring 19 is compressed to generate a restoring force. During the contraction, the extrusion plate 18 is driven by the corresponding linkage frame 17 to move horizontally, that is, the two extrusion plates 18 move together and approach each other, so that the wave-shaped oil absorption felt 13 is folded to a certain extent. When the roller 8 rolls from the protruding position to the recessed position, the telescopic slide rod 20 is reset and elongated by the restoring force of the first spring 19, that is, the two extrusion plates 18 are relatively separated, so that the oil absorption felt 13 is stretched and unfolded. Therefore, when the roller 8 repeatedly passes through the recessed and protruding positions of the wave-shaped guide rail 6, the oil absorption felt 13 can be repeatedly stretched and contracted, and the oil absorption felt 13 is only folded to a certain extent during this process, and is not completely folded and extruded together.

[0058] When the roller 8 moves to the corresponding position at the bottom of the wave-shaped guide rail 6 and acts on the second travel switch 27, the second travel switch 27 feeds back a signal, so that the motor controller controls the spindle of the servo motor 10 to reverse, and the roller 8 rolls along the wave-shaped guide rail 6 from bottom to top. When the two rollers 8 respectively roll to the positions corresponding to the inclined guide plates 12, the two rollers 8 roll upward along the inclined surfaces of the corresponding inclined guide plates 12. During this process, the telescopic slide rod 20 connected with the roller 8 is contracted due to the limiting and extruding action of the inclined guide plate 12, so that the two extrusion plates 18 are extruded and close to each other, so as to completely flatten the oil absorption felt 13 together, which facilitates the oil absorption felt 13 to squeeze out the oil absorbed. When the roller 8 rolls to the corresponding position at the top of the inclined guide plate 12, the roller 8 acts on the first travel switch 26, and the first travel switch 26 feeds back a signal, so that the motor controller controls the spindle of the servo motor 10 to rotate forward, so as to make the screw sleeve 9 descend. Therefore, the oil absorption felt 13 is indirectly driven by the screw sleeve 9 to move up and down reciprocatingly, which is convenient for separating the oil liquid from the sewage.

[0059] And when the extrusion plates 18 reciprocate transversely, the extrusion plates 18 drive the auxiliary sliding pipes 25 to slide relative to the main sliding pipe 14, and when the extrusion plates 18 drive the oil absorption felt 13 to move up and down, the main sliding pipe 14 slides along the strip-shaped sliding groove 24 longitudinally, facilitating the auxiliary sliding pipes 25 to move longitudinally with the extrusion plates 18, and in this process, the connecting hose 15 keeps the discharge pipe 23 in communication with the main sliding pipe 14, so that the flocculating agent in the storage tank 4 can be discharged from the discharge pipe 23, then flow to the main sliding pipe 14 along the connecting hose 15, and finally be sprayed from the auxiliary sliding pipes 25. Since the auxiliary sliding pipes 25 move up and down synchronously with the extrusion plates 18, the flocculating agent can be dispersed and mixed to different depths of the sewage, facilitating effective reaction and promoting the oil in the sewage to quickly polymerize and float up, facilitating the oil absorption felt 13 to absorb and process.

[0060] It should be noted that when the roller 8 is lifted to the corresponding position and close to the bottom of the inclined guide plate 12, the oil absorption felt 13 has been lifted to a position higher than the position of the recovery sliding box 2, and then the screw sleeve 9 continues to be lifted, so that the screw sleeve 9 drives the corresponding recovery sliding box 2 to slide into the processing cylinder 1 by relying on the elastic traction rope 28. When the roller 8 contacts the bottom of the corresponding inclined guide plate 12, the two recovery sliding boxes 2 are just butted together. In this process, the second spring 22 is compressed to generate a rebound force, the elastic traction rope 28 does not stretch and deform, and the recovery sliding box 2 is located directly below the oil absorption felt 13. The screw sleeve 9 continues to be lifted. Since the elastic traction rope 28 can stretch and deform, the screw sleeve 9 can stretch and deform the elastic traction rope 28 in this process, so that the screw sleeve 9 cannot be further lifted due to the position limitation of the recovery sliding box 2. Finally, when the roller 8 rolls to the top of the inclined guide plate 12 as the screw sleeve 9 is lifted, the extrusion plate 18 extrudes the oil absorption felt 13, facilitating the oil in the oil absorption felt 13 to be extruded out and fall into the recovery sliding box 2, achieving effective recovery. When the screw sleeve 9 is lowered, the oil absorption felt 13 is lowered. In the process of the oil absorption felt 13 descending close to the recovery sliding box 2, the recovery sliding box 2 slides out of the processing cylinder 1 by relying on the rebound force of the corresponding second spring 22, avoiding hindering the oil absorption felt 13 from descending. Thus, the oil in the sewage can be separated and processed repeatedly and effectively.

[0061] The above describes several embodiments of the present application in detail, but the embodiments of the present application are not limited to this, and cannot be considered to limit the scope of the present application. Any equivalent changes and improvements made within the scope of the present application should still belong to the patent scope of the present application.
