Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chemical product processing, in particular to a chemical product coalescence dewatering device based on hydrophilic-hydrophobic gradient material. BACKGROUND

[0002] In the process of chemical product processing, the water in the mixed liquid will seriously affect the product purity, equipment operation stability and subsequent process efficiency. For example, the water in crude oil will exacerbate pipeline corrosion and reduce refining efficiency, and the water in chemical solvents will affect reaction accuracy. In addition, the water and solid impurities in the mixed liquid will significantly affect the product purity and equipment operation efficiency. For example, the sand and emulsified water in crude oil will exacerbate the corrosion of refining equipment and block the pipeline, and the solid particles in chemical solvents will interfere with the coalescence dewatering effect. Therefore, an efficient coalescence dewatering device is a key link to ensure the quality and safety of chemical production.

[0003] The existing coalescence dewatering device mostly adopts a single filter structure and a fixed dosing mode. Typically, the mixed liquid is filtered through a single filter screen, then enters the coalescence device and separation device, and is discharged. Then, the impurities are manually cleaned. However, when the mixed liquid passes through the ordinary filter screen, the magnetic debris such as catalyst particles and non-magnetic impurities cannot be classified and treated. In addition, the single filter screen is easily blocked by particles of different sizes, which affects the output of the subsequent mixed liquid and the quality of coalescence. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a chemical product coalescence dewatering device based on hydrophilic-hydrophobic gradient material, which solves the problem that the existing coalescence dewatering device cannot classify and treat the magnetic debris such as catalyst particles and non-magnetic impurities contained in the mixed liquid before coalescence, and the single filter screen design is easily blocked by particles of different sizes, which affects the output of the subsequent mixed liquid and the quality of coalescence.

[0012] Preferably, the inner wall of the sieve disc is provided with two sieve plates from top to bottom. The aperture of the upper sieve plate is larger than that of the lower sieve plate. The lower surface of the push rod is slidably connected to the upper surface of the sieve plate. The inner wall of the outer shell is provided with a limiting groove. The slider and the push rod are both slidably connected to the inner wall of the limiting groove.

[0013] Preferably, a liquid collecting plate is provided inside the outer shell, which is located directly below the drum screen and the screen plate. A pretreatment assembly is provided between the liquid collecting plate and the coalescing tank. The pretreatment assembly includes a feed pipe that sequentially connects the liquid collecting plate and the coalescing tank. A strainer and a support ring are fixedly connected to the inner wall of the feed pipe. A rotating rod is rotatably connected to the inner wall of the strainer and the support ring. A worm gear and multiple actuating rods are fixedly connected to the outer wall of the rotating rod. A worm is rotatably connected to and passes through the inner wall of the feed pipe.

[0015] Preferably, the connecting block is rotatably connected to the outer wall of the connecting rod, the outer wall of the valve core is provided with a rubber sealing ring, and the float is made of polypropylene.

[0016] Working principle: When using this coalescence dehydration device to process chemical products, the motor is started, and the mixed liquid after chemical product processing is discharged from the feed port into the drum screen. When the motor starts, it drives the worm gear to rotate. The worm gear will drive the worm wheel to rotate through meshing. The worm wheel is fixedly connected to the drive rod, so the drive rod will be driven to rotate. Multiple fixed rods fixed to the drive rod drive the magnet frame and the drum screen to rotate. Multiple neodymium magnets are embedded in the magnet frame at equal intervals. After the drum screen frame is connected to the magnet frame, the entire drum will become magnetic. The mixed liquid will pass through the screen holes opened on the drum screen and fall into the screen plate below. Magnetic debris such as catalyst in the mixed liquid will be attracted to the drum. Screen plates with screen holes of different sizes are fixedly installed in the upper and lower layers inside the screen plate. After the mixed liquid falls onto the screen plate, the debris contained inside will remain on the screen plate. After multiple layers of screening, the mixed liquid continues to fall from the screen holes to the collection plate.

[0017] As the mixture passes through the drum screen, the power of the drive rod is transmitted to the transmission screw and the rotating screw in sequence through the sprocket and chain. During the rotation of the transmission screw, the slider connected to the thread on its outer wall will slide back and forth, and drive the baffle and abutment plate fixedly connected to the upper and lower sides to slide back and forth synchronously. During the back and forth sliding of the baffle, its top end always slides along the bottom end of the storage box installed on the inner wall of the outer shell. The storage box contains a flocculant that promotes agglomeration efficiency. A single discharge port is opened at its bottom end. During the back and forth sliding of the storage box, the discharge port is in a cycle of opening and closing. The flocculant inside will periodically and quantitatively fall through the discharge port into the drum screen below to mix and react with the mixture, promoting the subsequent agglomeration efficiency.

[0018] When the mixture passes through the sieve plate, the solid particles inside are screened and accumulated on the sieve plate. When the rotating screw is driven to rotate, the slider connected to the screw thread on the outer wall will drive the two push rods to slide back and forth against the top surface of the sieve plate, pushing the solid particles accumulated above evenly to the side to prevent clogging of the sieve holes. The mixture can also fall evenly from the sieve holes to the collection plate below, so that it can enter the subsequent coalescence tank evenly.

[0019] After passing through the collection plate, the mixture first passes through the pretreatment component and then enters the coalescence tank. The inner wall of the pretreatment component is equipped with a filter plate with multiple evenly spaced sieve holes. The inner wall of the filter plate is rotatably connected to a rotating rod, and a worm gear and multiple actuating rods are fixedly connected to the rotating rod. The worm gear meshes with the worm and is rotated by the worm, which in turn drives the rotating rod and actuating rods to rotate and slide along the surface of the filter plate. This performs the final filtration of the mixture and pushes the mixture to fall evenly from the multiple sieve holes into the coalescence tank below, improving the subsequent coalescence efficiency.

[0020] The bevel gear mounted on the outer wall of the drive rod meshes with two bevel gears simultaneously. One bevel gear drives the worm gear two to rotate, and the other bevel gear drives the drive shaft and gear one to rotate. Gear one then drives gear two and the centrifugal shaft to rotate through meshing, thereby driving the centrifugal tank to run.

[0021] The mixture enters a coalescing tank made of hydrophilic-hydrophobic gradient material through a pretreatment component to complete the coalescence process. It then enters a centrifuge tank via a transfer pipe. Inside the centrifuge tank, the mixture undergoes centrifugal stratification. The upper low-density layer enters a settling tank via a transfer pipe for gravity stratification, while the lower high-density liquid is discharged through outlet pipe one. When the water level in the settling tank reaches a set standard, buoyancy causes a float to rise with the water level. A connecting rod transmits the lift to a connecting block, which rotates around the connecting rod. This causes the valve core at the top of the connecting rod to slide along the inner wall of the transfer pipe, blocking the output pipe and preventing the mixture from entering the settling tank. This allows for separate processing of liquids of different densities within the settling tank. Low-density liquids flow out through outlet pipe two on the right side of the settling tank, while high-density liquids such as water flow out through outlet pipe one at the bottom. When the water level in the settling tank drops, the float descends, and the valve core slides in the opposite direction via component linkage, allowing the mixture to continue entering the settling tank. This process can be repeated.

[0022] The magnetic debris adsorbed on the drum screen will be touched by the multi-functional roller and fall into the recycling rack below as the drum screen rotates. After the separation is completed, the recycling rack can be pulled out to recycle and reuse the debris, and the remaining debris can be recycled by pulling out the screen plate.

[0023] This invention provides a device for the coalescence and dehydration of chemical products based on hydrophilic-hydrophobic gradient materials. It has the following beneficial effects:

[0024] 1. This invention uses a single motor to drive a worm gear to rotate, which, through the meshing of the worm wheel and worm gear and the linkage with the transmission assembly, transmits power to the uniform feeding assembly and the automatic screen cleaning assembly. This drives the drum screen to rotate and, in conjunction with the screen disc, performs multiple filtrations and screenings, thereby achieving the classification, filtration, and recovery of solid particles in the mixture according to their magnetic properties and particle size. At the same time, it drives the uniform feeding assembly to automatically add agglomerating agent to improve agglomeration efficiency and quality, and automatically cleans the drum screen and screen disc to reduce labor costs.

[0025] 2. This invention achieves automatic adjustment of liquid intake based on the water level in the settling tank by installing an automatic adjustment assembly consisting of a float, connecting rod, connecting block and valve core inside the settling tank. The float moves with the water level to drive the valve core to slide and control the opening and closing of the delivery pipe, thus facilitating the separate processing of liquids with different densities.

[0026] 3. This invention achieves fully automated processing of the mixture from filtration and coalescence to centrifugation and sedimentation separation by sequentially setting up an inlet, screen, recovery rack, coalescence tank, centrifugation tank and sedimentation tank in the device, and cooperating with a transmission pipe, discharge pipe and water pump, which facilitates the collection of liquid phases and solid particles.

[0027] 4. This invention achieves power transmission of a single motor by meshing the bevel gear and conical gear on the worm gear and the transmission between multiple gears on the transmission shaft, thereby driving the pretreatment components and centrifuge tank to operate, saving costs and ensuring synchronous operation of all components.

[0037] The technical solution of the present invention will now be clearly and completely described 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.

[0038] Example:

[0039] Please see the appendix Figure 1 -Appendix Figure 5This invention provides a chemical product coalescence dehydration device based on hydrophilic-hydrophobic gradient materials, comprising a housing 1, a motor 2 fixedly connected to the inner wall of the housing 1, a worm gear 3 fixedly connected to the output end of the motor 2, a drive rod 4, a transmission screw 10, a rotating screw 12, and multiple multifunctional rollers 9 rotatably connected to the inner wall of the housing 1, a worm wheel 5 and multiple fixed rods 6 fixedly connected to the outer wall of the drive rod 4, and a drum screen 8 fixedly connected to the outer walls of the multiple fixed rods 6, with multiple magnetic rollers fixedly connected to the outer wall of the drum screen 8. The iron frame 7 has a uniform feeding component 11 on the outer wall of the transmission screw 10. A transmission component 13 is provided between the drive rod 4, the transmission screw 10 and the rotating screw 12. The rotating screw 12 is a reciprocating screw. A slider 2 14 is threadedly connected to the outer wall of the rotating screw 12. Multiple push rods 15 are fixedly connected to the outer wall of the slider 2 14. A screen plate 16 is slidably connected to the inner wall of the outer shell 1. A coalescence tank 23, a centrifuge tank 24 and a settling tank 25 are provided on the inner wall of the outer shell 1. An automatic adjustment component is provided inside the settling tank 25.

[0040] Specifically, the outer casing 1 protects and secures the internal components, while a single motor 2 drives the subsequent components. The output of motor 2 drives the worm gear 3 to rotate, which in turn drives the worm wheel 5 and drive rod 4 to rotate. When drive rod 4 rotates, it drives the fixed rod 6, which is fixedly connected to its outer wall, and in turn drives the magnet frame 7 and the drum screen 8 to rotate. Multiple magnet frames 7 each contain multiple magnets, which, when installed on the outer wall of the drum screen 8, make the drum screen 8 magnetic. When the mixed liquid enters, it flows out from the screen holes of the drum screen 8, and the magnetic debris is attracted to the inner wall of the drum screen 8. The mixed liquid then flows vertically down into the lower screen plate 16 for secondary filtration. The two layers of screens on the inner wall of screen plate 16 enhance the filtration effect, with large particles remaining on the upper screen and small particles... The particles remain on the lower filter screen, facilitating separate processing of different particles by pulling out the screen plate 16 later. The power is transmitted to the uniform feeding component 11 and the rotating screw 12 through the transmission component 13. The reciprocating screw drives the slider one 1101 and slider two 14 to slide back and forth. During the reciprocating sliding of slider one 1101, the discharge port 1104 at the bottom of the storage box 1103 is blocked and opened repeatedly, so that the agglomerating agent stored inside is periodically released to increase the subsequent agglomeration efficiency. At the same time, it achieves the reciprocating contact with the multi-functional roller 9 to clean the attached debris and water stains. During the reciprocating sliding of slider two 14, the push rod 15 is driven to reciprocate to contact the surface of the screening plate 17 installed inside the screen plate 16, preventing solid particles from clogging the screen holes.

[0041] Please see the appendix Figure 2 Appendix Figure 3 and attached Figure 8The automatic adjustment component includes a conveying pipe 29, which passes through the inner walls of the centrifuge tank 24 and the settling tank 25 in sequence. A valve core 41 is slidably connected to the inner wall of the conveying pipe 29. A connecting block 39 is fixedly connected to the outer wall of the valve core 41. A connecting rod 40 is fixedly connected to the inner wall of the settling tank 25. One end of a connecting rod 38 is fixedly connected to the bottom of the outer wall of the connecting block 39. A float 37 is fixedly connected to the other end of the connecting rod 38. The connecting block 39 is rotatably connected to the outer wall of the connecting rod 40. A rubber sealing ring is provided on the outer wall of the valve core 41. The float 37 is made of polypropylene.

[0042] Specifically, the mixture enters the settling tank 25 from the centrifuge tank 24 through the delivery pipe 29 and undergoes static gravity stratification. As the mixture gradually enters, the float 37 floats at the top due to buoyancy and gradually rises in height in the vertical direction, causing one end of the connecting rod 38 to rise synchronously. Since the other end of the connecting rod 38 is fixedly connected to the connecting block 39, it causes the connecting block 39 to rotate around the connecting rod 40. The connecting rod 38 simultaneously limits the movement of the connecting block 39 and the entire buoyancy device. When the bottom end of the connecting block 39 rises with the connecting rod 38, its top end actuates the valve. The core 41 slides deeper into the delivery pipe 29, gradually blocking the outlet and slowing down the liquid inlet. When the water level is too high, the liquid inlet will stop, facilitating the separate processing of the stratified liquids. After processing, the water level drops, and the float 37 descends with the water level, which will drive the subsequent components to move in the opposite direction to discharge the liquid. The rubber sealing ring on the outer wall of the valve core 41 ensures that the mixture will not leak and has corrosion resistance and wear resistance. The polypropylene material of the float 37 ensures its resistance to acids and alkalis, oil, and corrosion, and it can float at the top, thereby driving the movement of the connecting rod 38 and the subsequent components through buoyancy.

[0043] Please see the appendix Figure 2 and attached Figure 3 The inner wall of the outer shell 1 is provided with a feed inlet 21 at the top. The feed inlet 21 is located at one end of the drum screen 8. The inner wall of the outer shell 1 is slidably connected with a screen plate 16 and multiple recycling racks 19. The screen plate 16 is located directly below the drum screen 8, and the recycling racks 19 are located at the bottom of the multi-functional roller 9. The inner walls of the coalescence tank 23 and the centrifuge tank 24 are connected by a transmission pipe 26. The inner walls of the centrifuge tank 24 and the settling tank 25 are both connected by a discharge pipe 1 28. The inner walls of the centrifuge tank 24 and the settling tank 25 are connected by a conveying pipe 29. The inner wall of the settling tank 25 is connected by a discharge pipe 20. The outer walls of the transmission pipe 26, the discharge pipe 1 28 and the discharge pipe 20 are all equipped with water pumps 27.

[0044] Specifically, the mixture first enters the drum screen 8 through the feed inlet 21, and after magnetic separation, it falls into the screen plate 16 for secondary screening. Then, it enters the coalescence tank 23 through the collection plate 20. The coalescence tank 23 is equipped with a treatment device made of hydrophilic-hydrophobic gradient materials, such as gradient membranes, gradient packing, and gradient fiber beds. When the water-containing fluid passes through the hydrophilic-hydrophobic gradient material, the hydrophilic end preferentially adsorbs tiny water droplets, causing them to aggregate on the material surface. As the fluid moves towards the hydrophobic end, the surface affinity for water decreases, and the water droplets are pushed and merged due to the surface energy difference, forming larger droplets, thereby increasing the coalescence effect and efficiency. Then, it enters the centrifuge tank 24 and the settling tank 25 through the transfer pipe 26. Through centrifugation and static separation, the large water droplets after coalescence are separated from the main liquid phase and discharged through the discharge pipe 1 28 and the discharge pipe 2 30, respectively. The solid particles after screening can be further classified, collected, and processed for reuse by removing the screen plate 16 and the recycling rack 19.

[0045] Please see the appendix Figure 4 and attached Figure 5 The teeth of the worm gear 3 and the worm wheel 5 are meshed together. The transmission assembly 13 includes multiple sprockets 1301. The sprockets 1301 are fixedly connected to the outer walls of the drive rod 4, the transmission screw 10 and the rotating screw 12 respectively. A chain 1302 is sleeved between the sprockets 1301 on the outer walls of the drive rod 4 and the transmission screw 10, and between the transmission screw 10 and the rotating screw 12.

[0046] Specifically, the power of the motor 2 is transmitted from the worm gear 3 to the worm wheel 5 through the meshing of the worm gear 3 and the worm wheel 5, resulting in deceleration and driving the subsequent drum screen 8 to run slowly, ensuring the stability and quality of screening. The power of the drive rod 4 is transmitted sequentially to the transmission screw 10 and the rotating screw 12 through the sprocket 1301 and the chain 1302. The transmission screw 10 drives the uniform feeding component 11 to operate, realizing the periodic addition of the agglomerating agent and the automatic cleaning of the multi-functional roller 9. The rotating screw 12 drives the slider 14 to slide back and forth, thereby achieving the effect of automatically cleaning the screen plate 16.

[0047] Please see the appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5 The outer wall of the multi-functional roller 9 is evenly provided with multiple scraper sections and load-bearing sections. The scraper sections are slidably connected to the outer wall of the drum screen 8, and the load-bearing sections are slidably connected to the outer wall of the magnet frame 7.

[0048] Specifically, the scraper section of the multi-functional roller 9 scrapes off the magnetic debris adsorbed on the drum screen 8, causing it to fall into the recycling rack 19 directly below. This facilitates the later extraction of the recycling rack 19 for the recycling and reuse of the metal and other magnetic debris, saving resources and costs. The load-bearing section of the multi-functional roller 9 limits and supports the magnet frame 7 and the drum screen 8, while ensuring the stability of the rotation of the magnet frame 7 and the drum screen 8.

[0049] Please see the appendix Figure 4 and attached Figure 5 The uniform feeding assembly 11 includes a slider 1101, a transmission screw 10 which is a reciprocating screw, a slider 1101 threadedly connected to the outer wall of the transmission screw 10, a storage box 1103 installed on the inner wall of the outer shell 1, a discharge port 1104 opened at the bottom of the storage box 1103, a baffle 1102 fixedly connected to the upper side of the outer wall of the slider 1101, a plurality of limiting rods 1106 fixedly connected to the inner wall of the outer shell 1, the upper surface of the baffle 1102 slidably connected to the bottom of the storage box 1103 and the discharge port 1104, the baffle 1102 slidably connected to the outer wall of the limiting rods 1106, an abutment plate 1105 fixedly connected to the lower side of the outer wall of the slider 1101 and the outer wall of the baffle 1102, and the outer wall of the abutment plate 1105 and the scraper section of the outer wall of the multi-functional roller 9 slidably connected to each other.

[0050] Specifically, during the rotation of the transmission screw 10, the slider 1101 is driven to slide back and forth through the reciprocating thread. A baffle 1102 is fixedly connected above the slider 1101. During the reciprocating sliding process, the upper surface of the baffle 1102 is always in close contact with the lower surface of the storage box 1103, and intermittently blocks the discharge port 1104. Thus, during the reciprocating sliding process, the agglomerating agent stored in the storage box 1103 flows out from the discharge port 1104 in stages and falls into the drum screen 8 directly below, where it mixes and reacts with the mixed liquid, improving the subsequent agglomeration effect. At the same time, the lower ends of the baffle 1102 and the slider 1101 are fixedly connected to the abutment plate 1105. During the reciprocating sliding process, the abutment plate 1105 reciprocates and slides against the outer wall of the scraper section of the multi-functional roller 9, cleaning the magnetic separation debris and liquid adhering to the scraper section, ensuring the quality of subsequent adsorption and scraping. At the same time, the sliding of the baffle 1102 is limited by the limiting rod 1106, so that it always maintains a straight sliding.

[0051] Please see the appendix Figure 6 The inner wall of the sieve plate 16 is provided with two sieve plates 17 from top to bottom. The aperture of the upper sieve plate 17 is larger than that of the lower sieve plate 17. The lower surface of the push rod 15 is slidably connected to the upper surface of the sieve plate 17. The inner wall of the outer shell 1 is provided with a limiting groove 18. The slider 14 and the push rod 15 are both slidably connected to the inner wall of the limiting groove 18.

[0052] Specifically, the sieve disc 16 performs a second screening and classification of solid particles in the mixture. The two sieve plates 17 enhance the filtration effect while keeping large particles on the surface of the upper sieve plate 17 and small particles on the surface of the lower sieve plate 17. This makes it convenient to remove the sieve disc 16 later for separate processing of different particles. During the reciprocating sliding process, the two push rods 15 respectively abut against the surfaces of the two sieve plates 17, pushing the solid particles accumulated on them to the side of the sieve disc 16, preventing clogging of the filter holes while ensuring the filtration quality of the intermediate filter holes.

[0053] Please see the appendix Figure 2 Appendix Figure 3 and attached Figure 7 The outer casing 1 has a liquid collection plate 20 inside, which is located directly below the drum screen 8 and the screen plate 16. A pretreatment component 22 is provided between the liquid collection plate 20 and the coalescing tank 23. The pretreatment component 22 includes a feed pipe 2201, which is connected to the liquid collection plate 20 and the coalescing tank 23 in sequence. A strainer 2202 and a support ring 2205 are fixedly connected to the inner wall of the feed pipe 2201. A rotating rod 2203 is rotatably connected to the inner wall of the strainer 2202 and the support ring 2205. A worm gear 2204 and multiple actuating rods 2206 are fixedly connected to the outer wall of the rotating rod 2203. A worm gear 2207 is rotatably connected to and passes through the inner wall of the feed pipe 2201. The teeth of the worm gear 2207 and the worm gear 2204 are meshed.

[0054] Specifically, the mixture slides uniformly through the inclined inner wall of the collection plate 20 into the pretreatment component 22 for final filtration and pretreatment. The feed pipe 2201 provides support for the operation of subsequent components. A filter plate 2202 is fixed inside the feed pipe 2201, and multiple filter holes are evenly distributed on its outer wall. During filtration, the mixture enters the coalescence tank 23 below evenly through the multiple filter holes. The mixture first falls onto the filter plate 2202. The top of the filter plate 2202 is rotatably connected to a rotating rod 2203. The rotating rod 2203 meshes with the rotating worm gear 2207 inside the feed pipe 2201 through a worm wheel 2204 fixed on the outer wall, thereby rotating and driving multiple actuating rods 2206 to slide and rotate along the surface of the filter plate 2202, ensuring that all the mixture falls evenly and preventing solid particles from clogging the filter holes.

[0055] Please see the appendix Figure 2 and attached Figure 3A bevel gear 31 is fixedly connected to the outer wall of the worm gear 3, and a drive shaft 32 is rotatably connected inside the outer shell 1. A bevel gear 33 is fixedly connected to the outer walls of both the worm gear 2207 and the drive shaft 32. A centrifugal shaft 34 is rotatably connected to the inner wall of the centrifugal tank 24. A gear 35 is fixedly connected to the outer wall of the drive shaft 32, and a gear 36 is fixedly connected to the outer wall of the centrifugal shaft 34. The bevel gear 31 and the bevel gear 33 are meshed, and the gear 35 and the gear 36 are meshed.

[0056] Specifically, a bevel gear 31 is fixed to the outer wall of the worm gear 3, which meshes with the bevel gears 33 on both sides. The bevel gear 33 on the left drives the worm gear 2207 to rotate, thereby driving the pretreatment component 22 to run. The bevel gear 33 on the right drives the transmission shaft 32 to rotate. The centrifugal shaft 34 at the other end of the transmission shaft 32 meshes with the gear 35, thereby driving the centrifugal shaft 34 to rotate, which in turn drives the centrifuge tank 24 to run. This realizes the transmission of power from the motor 2, further saves costs, and achieves synchronous operation of all components.
