Description

Technical Field

[0001] The present application relates to the technical field of oil mist purification equipment, and in particular to an integrated oil mist purifier based on environmental engineering. Background Art

[0002] Environmental engineering is an important branch of environmental science. It mainly studies how to protect and rationally utilize natural resources, improve environmental quality, and promote the coordination of environmental protection and social development. In environmental engineering, oil mist purifier is an important industrial environmental protection equipment, playing an irreplaceable role.

[0003] For related technology, reference may be made to Chinese patent publication number CN221182070U, which discloses a self-cleaning oil mist purifier device, including an oil mist purifier body, the interior of the oil mist purifier body being connected with a fixed frame and a filter layer, and an air intake pipe being fixedly connected to the oil mist purifier body at a position intermediate between the fixed frame and the filter layer. When the mechanical oil mist purifier is in use, air carrying oil mist from the outside enters the oil mist purifier through the air intake pipe. In the process of the air carrying oil mist entering the oil mist purifier through the air intake pipe, the air carrying oil mist is blown toward the filter structure. Since the size of the air intake pipe is much smaller than the size of the filter structure, the air carrying oil mist can only be blown toward the middle of the filter structure, resulting in the middle of the filter structure bearing a larger amount of filtration, while the edge of the filter structure bears a smaller amount of filtration. When the filter structure is replaced, the edge often does not reach the level where it needs to be replaced, thereby causing waste of the filter structure. Summary of the invention

[0007] Furthermore, the inflation structure includes: an outer tube, fixedly mounted on the inner wall of one side of the shell, an air filling hole being opened on the side wall of the outer tube near the air inlet pipe; a piston, slidingly sealed and mounted in the outer tube, one end extending out of the outer tube and pointing to the air outlet section of the air inlet pipe; a return spring, fixedly connected to one end of the piston in the outer tube; a power plate, fixedly connected to one end of the piston pointing to the air outlet section of the air inlet pipe; a one-way valve, fixedly mounted on one end of the outer tube close to the inner wall of the shell, the one-way valve being connected to the sealing bag through a connecting pipe.

[0008] Furthermore, the return spring is always in a compressed state.

[0009] Furthermore, the flow direction of the one-way valve is from the outer cylinder to the connecting pipe.

[0010] Furthermore, push grooves are provided on the side walls of the shells on both sides of the air inlet pipe, and the push grooves are lower inclined grooves close to the filter element. The push grooves are provided with: a movable plate slidably installed in the push groove, one end of which extends into the installation slide groove and rests against the sealing bag close to the air inlet pipe; a support spring fixedly connected to the other end of the movable plate; the two movable plates are fixedly connected to the two ends of the support rod, and the support rod is directly below the air outlet section of the air inlet pipe.

[0011] Furthermore, limiting grooves are provided on the side walls of the shells on both sides of the air inlet pipe, and the limiting grooves are provided with: a limiting rod, both ends of which are slidably provided in the limiting grooves, and the bottom end of the limiting rod is close to the upper end of the air outlet section of the air inlet pipe; an extrusion spring, which is fixedly connected to the top of the limiting rod in the limiting groove; a shaking bar is fixedly installed on the position of the limiting rod close to the frame of the filter structure, and the shaking bar points to the frame of the filter structure; a number of shaking blocks are equidistantly provided on the frame of the filter structure facing the shaking bar, and a push switch is fixedly installed on the frame above the shaking block; an electromagnetic valve is fixedly installed on the sealing bag, and the electromagnetic valve is connected to the inside of the sealing bag, and the electromagnetic valve, the push switch and the control system are electrically connected.

[0012] Furthermore, the solenoid valve is a normally closed solenoid valve; the shaking block is an isosceles triangle block, and one end of the shaking bar facing the shaking block is a symmetrically arranged inclined surface.

[0013] This application has the following beneficial effects:

[0014] 1. The present application provides an integrated oil mist purifier based on environmental engineering. When the oil mist purifier is working, the control system controls the power cylinder to start intermittently, so that the power cylinder drives the rack to move back and forth, and the reciprocating rack drives the gear and the air outlet section of the intake pipe to rotate, thereby changing the angle of the air outlet section toward the filter structure, so that the time for the gas containing oil mist to be sprayed to each position of the filter structure is the same, preventing the phenomenon that the filtering amount in the middle position and the edge position of the filter structure is different due to the different time for the gas containing oil mist to be blown to each position of the filter structure.

[0015] 2. The present application provides an integrated oil mist purifier based on environmental engineering. In the process in which the power cylinder drives the rack to move, and the rack drives the gear and the air outlet section of the intake pipe to rotate, the air outlet section of the intake pipe pushes the power plate and the piston, so that the gas in the outer cylinder enters the sealing bag through the one-way valve and the connecting pipe, so that the sealing bag expands, and the gap between the filter structure and the mounting groove is blocked, preventing the gas containing oil mist from passing through the gap between the filter structure and the mounting groove, thereby avoiding a certain amount of oil mist in the discharged gas, affecting the purification rate of the oil mist purifier.

[0016] 3. The present application provides an integrated oil mist purifier based on environmental engineering. During the expansion of the sealing bag, the sealing bag pushes the movable plate to slide in the pushing groove, so that the movable plate drives the support rod to move, and the support rod pushes the air outlet section of the air inlet pipe to rotate upward, thereby changing the elevation angle of the air outlet section of the air inlet pipe, and further changing the angle of the air outlet section of the air inlet pipe toward the filtering structure, so that the gas with oil mist can be evenly sprayed toward the filtering structure.

[0017] 4. The present application provides an integrated oil mist purifier based on environmental engineering. When the air outlet section of the air inlet pipe is tilted to the maximum angle, the air inlet pipe pushes the limit rod and the shaking bar to move upward. When the shaking bar touches the push switch, the push switch opens the solenoid valve through the control system, and the gas in the sealing bag is discharged through the solenoid valve. At this time, due to the discharge of the gas in the sealing bag, the supporting spring pushes the movable plate and the supporting rod to reset, and the air outlet section of the air inlet pipe rotates downward. At the same time, under the action of the extrusion spring, the limit rod and the shaking bar move downward. During the downward movement of the shaking bar, they slide relative to the shaking block, so that the shaking block drives the filter structure to shake rapidly, thereby shaking off the oil droplets on the filter structure, preventing the oil droplets on the filter structure from condensing and clogging the filter holes of the filter structure, thereby extending the service life of the filter structure.

A vertically installed rotating shaft runs through the middle of the air outlet section, and the bottom end of the rotating shaft is fixedly connected to the bottom end of the shell 1. The connecting hole between the air outlet section and the rotating shaft is an oblong hole, and the length direction of the oblong hole is in the same direction as the axis of the air outlet section; a power cylinder 5 is fixedly installed on the inner wall of the shell 1 close to the air inlet pipe 101, and a rack 501 is fixedly connected to the output end of the power cylinder 5, and the rack 501 meshes with the gear 4. A support rod 11 is provided at the bottom end of the air outlet section of the air inlet pipe 101. The support rod 11 is used to support the air outlet section of the air inlet pipe 101. Both ends of the support rod 11 are connected to the inner wall of the shell 1. When performing purification operations, the control system controls the power cylinder 5 to start intermittently, so that the output end of the power cylinder 5 pushes the rack 501 to move back and forth, and the reciprocating rack 501 drives the air outlet section to rotate left and right around the rotation axis, so that the rotating section similar to the bellows structure is deflected to a certain extent, so that the air outlet section of the air inlet pipe 101 is intermittently rotated to both sides, and the position of the air outlet section of the air inlet pipe 101 toward the filter structure 2 is intermittently changed, so that the edges on both sides of the filter structure 2 can face the air with oil mist, so that the air with oil mist entering through the air inlet pipe 101 is sprayed to the middle position and the two side positions of the filter structure 2 at the same time.

[0032] See also Figure 2-Figure 4A sealing capsule 6 is fixedly installed in the installation slide groove 104 of the shell 1, and the sealing capsule 6 wraps the frame of the filter structure 2; an inflatable structure 7 is fixedly installed on the inner wall of one side of the shell 1, and the inflatable structure 7 includes an outer cylinder 701, a piston 702, a return spring 703, a power plate 704 and a one-way valve 705.

A one-way valve 705 is fixedly installed at one end of the outer tube 701 close to the inner wall of the shell 1, and the one-way valve 705 is connected to the sealing bag 6 through the connecting pipe 8; the return spring 70 3 is always in a compressed state; the return spring 703 in the compressed state provides power for the return of the piston 702, ensuring that the power plate 704 on the piston 702 can be close to the outlet section of the intake pipe 101, and when the outlet section of the intake pipe 101 rotates, it can push the power plate 704 and the piston 702 to move; when the output end of the power cylinder 5 drives the rack 501 to move back and forth, and the rack 501 drives the gear 4 and the outlet section of the intake pipe 101 to rotate, the outlet section of the intake pipe 101 will squeeze the power plate 704 of the inflatable structure 7, so that the power plate 704 drives the piston 702 to slide into the outer tube 701. At this time, the piston 702 squeezes the gas inside the outer tube 701, so that the gas enters the sealing bag 6 through the one-way valve 705 and the connecting pipe 8. During long-term use, the sealing bag 6 expands to block the gap between the filter structure 2 and the mounting slide groove 104, preventing the gas with oil mist from passing through the gap between the filter structure 2 and the mounting slide groove 104. The flow direction of the one-way valve 705 is from the outer tube 701 to the connecting pipe 8; when the power plate 704 and the piston 702 are squeezed by the outlet section of the intake pipe 101, the piston 702 squeezes the gas in the outer tube 701, so that the gas in the outer tube 701 can pass through the one-way valve 705 into the connecting pipe 8 and the sealing bag 6, and prevents gas backflow.

[0033] See also Figure 5 and Figure 6A push groove 105 is provided on the side walls of the housing 1 on both sides of the air inlet pipe 101, and the position of the push groove 105 is lower than the height of the air inlet pipe 101. The push groove 105 is a lower inclined groove close to the filter element 3. A moving plate 9 is slidably installed in the push groove 105. One end of the moving plate 9 extends into the installation slide groove 104 and abuts against the sealing bag 6 close to the air inlet pipe 101. The other end of the moving plate 9 is fixedly connected to a support spring 10. The support spring 10 is arranged in the push groove 105. The two moving plates 9 are fixedly connected to the support rod 11. Both ends, and the support rod 11 is directly below the outlet section of the air inlet pipe 101; during the expansion of the sealing bag 6, the expanded sealing bag 6 pushes the movable plate 9 close to the sealing bag 6 to move along the inclined direction of the pushing groove 105, and the movable plate 9 drives the support rod 11 to move synchronously. At the same time, the support rod 11 moving obliquely upward pushes the outlet section of the upper air inlet pipe 101 to rotate upward, thereby further changing the angle of the outlet section of the air inlet pipe 101 toward the filter structure 2, so that the gas with oil mist can be evenly sprayed toward the filter structure 2.

[0034] See also Figure 7 and Figure 8The side walls of the housing 1 on both sides of the air inlet pipe 101 are provided with limiting grooves 106, and the position of the limiting grooves 106 is higher than the position of the air inlet pipe 101. The limiting rods 12 are slidably installed in the limiting grooves 106. The top of the limiting rod 12 in the limiting grooves 106 is fixedly connected with an extrusion spring 13. The top of the extrusion spring 13 is fixedly connected to the inner wall of the limiting groove 106. The bottom end of the limiting rod 12 is close to the upper end of the air outlet section of the air inlet pipe 101. The limiting rod 12 is fixed near the frame of the filter structure 2.

In the process of exhausting the sealing bag 6, the sealing bag 6 contracts, and the support spring 10 pushes the moving plate 9 and the support rod 11 to return to the initial position The air outlet section of the air inlet pipe 101 rotates downward, and at the same time, the extrusion spring 13 pushes the limit rod 12 and the shaking bar 14 to move downward. During the downward movement of the shaking bar 14, the top of the shaking bar 14 and the shaking block 201 slide rapidly relative to each other, and the top of the shaking bar 14 squeezes the shaking block 201, so that the shaking block 201 drives the filter structure 2 to squeeze the sealing bag 6 to produce rapid shaking, thereby shaking off the oil droplets on the filter structure 2, preventing the oil droplets on the filter structure 2 from condensing and clogging the filter holes of the filter structure 2.

[0035] The solenoid valve 601 is a normally closed solenoid valve. Under normal conditions, it ensures that the gas in the sealing bag 6 will not leak. When the gas in the sealing bag 6 needs to be discharged, the control system starts the solenoid valve 601 to open it.

[0036] The shaking block 201 is an isosceles triangle block, and the end of the shaking bar 14 facing the shaking block 201 is a symmetrically arranged inclined surface, so as to ensure that the end of the shaking bar 14 facing the shaking block 201 can slide relative to the shaking block 201, and the shaking block 201 will not hinder the movement of the shaking bar 14.

[0037] The working principle of the present invention is as follows:

[0038] See also Figure 1-Figure 3When the oil mist purifier is used to purify the oil mist, the fan draws the air with oil mist from the outside into the housing 1 from the air inlet pipe 101. At this time, the air with oil mist entering from the air inlet pipe 101 is blown toward the filter structure 2, so that the filter structure 2 filters the air with oil mist. At the same time, the control system controls the power cylinder 5 to start intermittently, so that the output end of the power cylinder 5 pushes the rack 501 to move back and forth, and the reciprocating rack 501 drives the air outlet section to move left and right, so that the rotating section similar to the bellows structure is deflected to a certain extent, so that the air outlet section of the air inlet pipe 101 is intermittently rotated to both sides, and the position of the air outlet section of the air inlet pipe 101 toward the filter structure 2 is intermittently changed, so that the edges on both sides of the filter structure 2 can directly face the air with oil mist, so that the air with oil mist entering through the air inlet pipe 101 is sprayed to the middle position and the two side positions of the filter structure 2 at the same time, so as to prevent the phenomenon that the filtering amount of the middle position and the two side positions of the filter structure 2 is different due to the different time of the gas with oil mist blowing to the middle position and the two side positions of the filter structure 2.

[0039] See also Figure 1-Figure 5 , when the output end of the power cylinder 5 drives the rack 501 to move back and forth, and the rack 501 drives the gear 4 and the air outlet section of the air inlet pipe 101 to rotate, the air outlet section of the air inlet pipe 101 will squeeze the power plate 704 of the inflatable structure 7, so that the power plate 704 drives the piston 702 to slide into the outer tube 701. At this time, the piston 702 squeezes the gas inside the outer tube 701, so that the gas in the outer tube 701 enters the sealing bag 6 through the one-way valve 705 and the connecting pipe 8. During long-term use, the gas entering the sealing bag 6 increases, thereby further expanding the sealing bag 6, and blocking the gap between the filter structure 2 and the installation slide groove 104 (when the air pressure of the gas in the sealing bag 6 reaches the set pressure, the solenoid valve 601 will be activated to discharge the gas), preventing the gas with oil mist from passing through the gap between the filter structure 2 and the installation slide groove 104, thereby avoiding a certain amount of oil mist in the discharged gas, affecting the purification rate of the oil mist purifier.

[0040] See also Figure 1-Figure 8 During the expansion of the sealing bag 6, the expanded sealing bag 6 pushes the moving plate 9 close to the sealing bag 6 to move along the inclined direction of the pushing groove 105. When the moving plate 9 moves, the moving plate 9 drives the support rod 11 to move along the inclined direction of the pushing groove 105. At the same time, the support rod 11 moving obliquely upward pushes the outlet section of the upper air inlet pipe 101 to rotate upward, thereby further changing the angle of the outlet section of the air inlet pipe 101 toward the filter structure 2, so that the gas with oil mist can be evenly sprayed toward the filter structure 2;

[0041] While the air outlet section of the air inlet pipe 101 rotates upward, the top end of the air outlet section of the air inlet pipe 101 pushes the upper limit rod 12 and the shaking bar 14 to slide upward in the limit groove 106 until the limit rod 12 slides to the uppermost end, and the shaking bar 14 on the limit rod 12 presses the push switch 202, and the push switch 202 is activated, so that the control system opens the solenoid valve 601, and part of the gas in the sealing bag 6 is discharged through the solenoid valve 601. In the process of exhausting the sealing bag 6, the sealing bag 6 contracts, and the support spring 10 pushes the movable plate 9 and the support rod 11 to return To the initial position, the air outlet section of the air inlet pipe 101 rotates downward, and at the same time, the extrusion spring 13 pushes the limit rod 12 and the shaking bar 14 to move downward. In the process of the shaking bar 14 moving downward, the top of the shaking bar 14 and the shaking block 201 slide rapidly relative to each other, and the top of the shaking bar 14 squeezes the shaking block 201, so that the shaking block 201 drives the filter structure 2 to squeeze the sealing bag 6 to produce rapid shaking, shake off the oil droplets on the filter structure 2, prevent the oil droplets on the filter structure 2 from condensing and clogging the filter holes of the filter structure 2, thereby extending the service life of the filter structure 2.
