Description

Technical Field

[0001] The invention relates to the technical field of industrial wastewater treatment, in particular to an oil-absorbing felt type oil removal device for industrial wastewater pretreatment. Background Art

[0002] Some industrial wastewater contains oil. When it is treated, the common method is to add chemicals to convert the pollutants in the wastewater into harmless substances to purify the wastewater. The main method for treating oily wastewater is coagulation, that is, adding flocculants to the oily wastewater. After hydrolysis in water, the positively charged micelles and the negatively charged emulsified oil are electrically neutralized, the oil particles aggregate, the particle size becomes larger, and floccules are generated to adsorb fine oil droplets. Then, oil and water are separated by sedimentation or flotation. Common flocculants include inorganic flocculants such as polyaluminium chloride (PAC), ferric chloride, aluminium sulfate, ferrous sulfate, and organic polymer flocculants such as acrylamide and polyacrylamide (PAM). This method of treating oily wastewater is mainly achieved by adding chemicals. When facing wastewater containing a large amount of oil, a lot of chemicals need to be used, which is costly. If too many chemicals are added, these remaining chemicals will remain in the wastewater, causing secondary pollution. Summary of the invention

[0003] The purpose of the present invention is to solve the shortcomings of the prior art treatment method of adding too much reagent, which is high in cost and may cause secondary pollution, and to propose an oil absorption felt type oil removal device for industrial wastewater pretreatment.

[0007] When the oil suction mechanism is in the second working state, the spline shaft drives the oil suction mechanism to move outside the top plate, the first magnetic suction member no longer generates a downward force on the second magnetic suction member on the oil suction mechanism, and the first spring pushes the oil suction mechanism to reset, so that the oil suction mechanism can be squeezed by the squeezing roller in the second storage chamber but cannot be squeezed by the partition.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example 1

[0025] Reference Figure 1-7An oil-absorbing felt type oil removal device for industrial wastewater pretreatment includes a barrel body 1, which is fixedly mounted on a base 2. A partition 3 is fixedly mounted inside the barrel body 1. The partition 3 divides the inside of the barrel body 1 into two mutually isolated first storage chambers and second storage chambers. Two liquid outlet pipes 4 are fixedly mounted at the bottom of the barrel body 1. Valves are arranged on the liquid outlet pipes 4. The valves are used to control the outflow of liquid in the storage chamber. The two liquid outlet pipes 4 are respectively connected to the first storage chamber and the second storage chamber. A liquid inlet pipe 5 connected to the first storage chamber is also fixedly mounted on the barrel body 1. A valve is also arranged on the liquid inlet pipe 5. A spline shaft 6 is placed above the partition 3. The spline shaft 6 is preferably a cross spline shaft. The spline shaft 6 is coaxially arranged with the barrel body 1, and the bottom end of the spline shaft 6 is rotatably connected to the partition 3, and the top end of the spline shaft 6 is coaxially connected with the fixed shaft 7, and the fixed shaft 7 is transmission-connected with a rotation drive module, and the rotation drive module includes a gear 13, a rack 14, and a linear reciprocating motion mechanism. The fixed shaft 7 is fixedly mounted with a coaxial gear 13, and a rack 14 meshing with the gear 13 is arranged on one side of the gear 13, and the rack 14 is fixedly mounted on the linear reciprocating motion mechanism, and the linear reciprocating motion mechanism is used to drive the rack 14 to perform linear reciprocating motion; the linear reciprocating motion mechanism It includes a first fixed block 15, a guide rod 16, a vertical plate 17, a second fixed block 18, and a second spring 19. The vertical plate 17 is fixedly connected to the base 2. A plurality of guide rods 16 parallel to each other are arranged through the vertical plate 17. The guide rods 16 are all arranged parallel to the rack 14. One end of the guide rod 16 is fixedly connected to the first fixed block 15, and the other end of the guide rod 16 is fixedly connected to the second fixed block 18. The first fixed block 15 is fixedly connected to the rack 14, and a second spring 19 is sleeved on the guide rod 16 between the first fixed block 15 and the vertical plate 17. The operator pulls the second fixed block 18 on the linear reciprocating motion mechanism outward, and at this time the second fixed block 18 pulls the first fixed block 15 outward through the guide rod 16, and the first fixed block 15 compresses the second spring 19, and the first fixed block 15 pulls the rack 14 outward, and the rack 14 drives the gear 13 to drive the fixed shaft 7 to rotate in the forward direction, and then the operator releases the second fixed block 18. Under the action of the restoring force of the second spring 19, the first fixed block 15 is reset, and the first fixed block 15 pushes the rack 14 to drive the gear 13 to drive the fixed shaft 7 to rotate in the reverse direction, thereby realizing the linear reciprocating drive of the rack 14.

[0026] The diameter of the fixed shaft 7 is greater than the diameter of the spline shaft 6 , so that the fixed shaft 7 can be used to limit the connecting sleeve 20 to prevent the connecting sleeve 20 from falling off the spline shaft 6 . A top plate 8 is arranged above the first storage chamber, the top plate 8 is fixedly connected to the barrel body 1, a first magnetic component is fixedly installed on the top plate 8, an oil suction mechanism is sleeved on the spline shaft 6 below the top plate 8, a first spring 10 is sleeved on the spline shaft 6 between the oil suction mechanism and the partition 3, a second magnetic component is installed on the oil suction mechanism, the second magnetic component and the first magnetic component repel each other, a corresponding squeezing roller 12 is installed in the second storage chamber below the oil suction mechanism, the oil suction mechanism includes a connecting sleeve 20, a cross plate 21, and an oil-absorbing felt 22, a connecting sleeve 20 adapted thereto is sleeved on the spline shaft 6 below the top plate 8, a first spring 10 is sleeved on the spline shaft 6 between the connecting sleeve 20 and the partition 3, a cross plate 21 is fixedly connected to the connecting sleeve 20, an oil-absorbing felt 22 is fixedly installed on the lower surface of the cross plate 21, and a second magnetic component is fixedly installed on the upper surface of the cross plate 21. The oil-absorbing felt 22 is made of inert chemical polypropylene through a melt-blown process, and it can effectively absorb and retain liquid. The adsorption products are all wrapped in polypropylene fibers or non-woven fabrics treated with surface activating agents and sewn with thread. The outer layer of the fabric is extremely tough and durable, has strong capillary absorption, and brings extremely strong adsorption. The oil-absorbing felt 22 can be reused and is very environmentally friendly.

[0027] The oil suction mechanism has a first working state and a second working state, and the rotation drive module is used to drive the fixed shaft 7 to drive the spline shaft 6 to perform periodic reciprocating rotation, so that the spline shaft 6 drives the oil suction mechanism to switch between the first working state and the second working state;

[0028] When the oil suction mechanism is in the first working state, the spline shaft 6 drives the oil suction mechanism to move below the top plate 8, and the first magnetic suction member on the top plate 8 exerts a downward force on the second magnetic suction member on the oil suction mechanism. The second magnetic suction member drives the oil suction mechanism to move downward along the spline shaft 6 and compresses the first spring 10, so that the oil suction mechanism can contact the wastewater liquid surface stored in the first storage chamber; when in the first working state, due to the force of the second magnetic suction member on the first magnetic suction member, the entire oil suction mechanism will move downward when passing below the top plate 8 until the oil absorption felt 22 on the oil suction mechanism contacts the wastewater surface in the first storage chamber. Since oil-water stratification occurs on the surface of the wastewater input into the first storage chamber, the oil is located on the surface of the wastewater. When the oil absorption felt 22 contacts the wastewater liquid surface, it will absorb the oil on the surface of the wastewater.

[0029] When the oil suction mechanism is in the second working state, the spline shaft 6 drives the oil suction mechanism to move outside the top plate 8, the first magnetic suction member no longer exerts a downward force on the second magnetic suction member on the oil suction mechanism, and the first spring 10 pushes the oil suction mechanism to reset, so that the oil suction mechanism can be squeezed by the squeezing roller 12 in the second storage chamber, but cannot be squeezed by the partition 3. When in the second working state, since the oil absorption felt 22 absorbs the oil, at this time, since the height of the wastewater level is less than or equal to the height of the partition 3, if the oil absorption mechanism is not reset, the oil absorption felt 22 thereon will be squeezed with the partition 3, causing the oil on the oil absorption felt 22 to be squeezed out and then flow back into the first storage chamber. After the oil absorption mechanism is reset under the action of the first spring 10, it rises to a height higher than the partition 3, so that it will not be squeezed with the partition 3; after the oil absorption mechanism is reset, most of the oil absorption mechanism will be in a position above the squeezing roller 12, so that when the oil absorption mechanism moves to the second storage chamber position, the oil absorption felt 22 thereon will be squeezed by the squeezing roller 12, and the oil on the oil absorption felt 22 will be squeezed out and fall into the second storage chamber.

[0030] When the present invention is in use, the operator injects the oily wastewater to be treated into the first storage chamber in the barrel body 1 through the liquid inlet pipe 5. After the wastewater in the first storage chamber undergoes oil-water stratification, the operator operates the rotary drive module to drive the oil suction mechanism to rotate between the first working state and the second working state. When the oil suction mechanism is in the first working state, the oil suction mechanism absorbs the oil on the surface of the wastewater in the first storage chamber. When the oil suction mechanism is in the second working state, the oil suction mechanism is squeezed with the squeezing roller 12, thereby squeezing the oil absorbed in the oil suction mechanism into the second storage chamber, thereby achieving pretreatment of the oily wastewater.

[0031] Example 2

[0032] Reference Figure 1-7 As another preferred embodiment of the present invention, the difference from embodiment 1 is that it further includes a filtering module, which is arranged above the barrel 1 and is connected to the liquid outlet pipe 4. The filtering module is mainly used to filter the residue in the oily wastewater to prevent some residue from floating on the surface of the wastewater, resulting in the oil absorption mechanism being unable to fully absorb the oil on the surface of the wastewater.

[0033] The filtering module includes a residue collecting mechanism, a ring 23, a conical net bag 24, a pull rod 25, and a power module. The ring 23 is installed on the residue collecting mechanism. The residue collecting mechanism includes an ash hopper 26 and a cylinder 27. The ash hopper 26 is fixedly connected to the base 2. The opening side of the ash hopper 26 is inclined toward the base 2. The cylinder 27 is penetrated by the ash hopper 26. The cylinder 27 is fixedly connected to the ash hopper 26. The cylinder 27 is arranged parallel to the barrel body 1, and the ring 23 is coaxially fixedly installed in the cylinder 27. A conical net bag 24 coaxially arranged therewith is fixed in the circular ring 23, the tip of the conical net bag 24 is arranged toward the base 2, a pull rod 25 coaxially arranged therewith is placed in the conical net bag 24, the pull rod 25 is coaxially arranged with the cylinder 27, the bottom end of the pull rod 25 is fixedly connected to the tip of the conical net bag 24, the pull rod 25 is fixedly connected to the power module, the power module is used to drive the pull rod 25 to perform linear reciprocating motion along the central axis direction of the circular ring 23, the power module is also connected to the rotation drive module, and a corresponding funnel 33 is arranged directly below the conical net bag 24, and the bottom end of the funnel 33 is connected to the liquid inlet pipe 5. The funnel mainly collects the wastewater flowing out of the conical net bag 24 and then injects it into the liquid inlet pipe 5. When the power module pulls the pull rod 25 upward to the highest position, the conical net bag 24 is set in an inverted cone shape. At this time, the tip of the conical net bag 24 is set toward the top of the ring 23. The residue intercepted in the conical net bag 24 will be poured out, and the poured residue will fall into the ash hopper 26 and then flow out along the inclined direction of the ash hopper 26.

[0034] The power module includes a connecting member 28, a hydraulic rod 29, a support frame 30, and a transmission mechanism. The top of the pull rod 25 is fixedly connected to the connecting member 28, and the connecting member 28 is fixedly mounted on the hydraulic rod 29. The hydraulic rod 29 is used to drive the connecting member 28 to perform linear reciprocating motion along the central axis of the cylinder 27. The hydraulic rod 29 is fixedly mounted on the support frame 30, and the support frame 30 is fixedly mounted on the base 2. The connecting member 28 and the rotation drive module are connected through the transmission mechanism. The transmission mechanism includes a guide pulley assembly 31 and a pull rope 32. The guide pulley assembly 31 is fixedly mounted on the support frame 30. One end of the pull rope 32 is fixedly connected to the connecting member 28, and the other end of the pull rope 32 is fixedly connected to the rotation drive module after passing through the pulley assembly 31. In practice, the other end of the pull rope 32 is fixedly connected to the second fixed block 18 after passing through the pulley assembly 31. When the hydraulic rod 29 pushes the connecting member 28 to make a linear reciprocating motion, the connecting member 28 pulls the pull rope 32 back and forth. Due to the guiding effect of the guide pulley assembly 31, the pull rope 32 pulls the rotating drive module back and forth, thereby driving the rotating drive module. In this way, the hydraulic rod 29 can be used as a power source to drive two modules, thereby simplifying the power mechanism and reducing the equipment cost.

[0035] When the present invention is in use, the operator pours the wastewater into the conical net bag 24, and the conical net bag 24 intercepts the residue in the wastewater. When the residue in the conical net bag 24 is collected to a certain extent, the operator stops pouring the wastewater and then starts the power module. The power module can pour out the residue collected in the conical net bag 24. At the same time, the power module also synchronously drives the rotation drive module to operate.

[0036] The overall workflow of the present invention is as follows:

[0037] S1. The operator pours the wastewater into the conical net bag 24 in the filter module. When the wastewater passes through the conical net bag 24, the conical net bag 24 intercepts most of the residues in the wastewater. The filtered wastewater flows into the funnel 33 after passing through the conical net bag 24, and then is collected by the funnel 33 and then injected into the first storage chamber through the liquid inlet pipe 5. When the wastewater in the first storage chamber is collected to a specified height, the operator stops pouring the wastewater;

[0038] S2, the operator starts the power module, controls the hydraulic rod 29 in the power module to push the connecting member 28 upward, and when the connecting member 28 pulls the pull rod 25 upward to the highest position, the conical net bag 24 is set in an inverted cone shape (such as Figure 7 As shown), at this time, the tip of the conical net bag 24 is set toward the top of the ring 23, and the residue intercepted in the conical net bag 24 will be poured out, and the poured residue falls into the ash hopper 26, and then flows out along the inclined direction of the ash hopper 26. The operator sets a collection container under the ash hopper 26 to collect the outflowing residue;

[0039] During this process, the connecting member 28 also pulls the pull rope 32 synchronously, and the pull rope 32 pulls the second fixed block 18 outward. At this time, the second fixed block 18 pulls the first fixed block 15 outward through the guide rod 16, and the first fixed block 15 compresses the second spring 19. The first fixed block 15 pulls the rack 14 outward, and the rack 14 drives the gear 13 to drive the fixed shaft 7 to rotate forward. During this forward rotation process, the fixed shaft 7 drives the spline shaft 6 to rotate forward synchronously, and the spline shaft 6 drives the oil suction mechanism set thereon to switch between the first working state and the second working state; when in the first working state, due to the second Due to the force of the magnetic element on the first magnetic element, the entire oil suction mechanism will move downward when passing under the top plate 8 until the oil suction felt 22 on the oil suction mechanism contacts the surface of the wastewater in the first storage chamber, and absorbs the oil on the surface of the wastewater; when the oil suction mechanism is in the second working state, and after the oil suction mechanism is reset under the action of the first spring 10, most of the oil suction mechanism will be in a position above the squeezing roller 12, so that when the oil suction mechanism moves to the second storage chamber position, the oil suction felt 22 thereon will be squeezed by the squeezing roller 12, and the oil on the oil suction felt 22 will be squeezed out, so as to fall into the second storage chamber;

[0040] S3, the operator controls the hydraulic rod 29 in the power module to pull the connecting piece 28 downward, and the connecting piece 28 drives the pull rod 25 to return to the initial position, so that the tip of the conical net bag 24 is set toward the bottom of the ring 23 (such as Figure 6 shown);

[0041] During this process, under the restoring force of the second spring 19, the first fixed block 15 is reset, and the first fixed block 15 pushes the rack 14 to drive the gear 13 to drive the fixed shaft 7 to rotate in the opposite direction. During this reverse rotation process, the fixed shaft 7 drives the spline shaft 6 to rotate in the opposite direction synchronously, and the spline shaft 6 drives the oil suction mechanism arranged thereon to switch between the first working state and the second working state again, thereby performing another oil removal operation.

[0042] S4. After the wastewater treatment is completed, the operator opens the valves on the two liquid outlet pipes 4, thereby discharging the deoiled wastewater in the first storage chamber to the wastewater treatment device, and discharging the oil collected in the second storage chamber to the oil collection device.

[0043] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
