Description

Technical Field

[0001] The invention relates to the technical field of rotary filter screens, in particular to an installation structure of an ultra-deep rotary filter screen. Background Art

[0002] The rotary filter is a filtering device widely used in water treatment, industrial liquid filtration, air filtration and other fields. It can automatically remove various small-volume impurities such as aquatic plants, branches, plastics, and films from the water source to ensure the cleanliness of the back-end equipment or media; in order to purify the extracted water source; the installation steps of this rotary filter are as follows: first, excavate the foundation pit; then install the foundation frame in the foundation pit; then use the lifting equipment to lift the rotary filter on the foundation frame, and connect the rotary filter and the foundation frame; finally, assemble the mesh frame of the rotary filter on the frame of the rotary filter. After completing the installation of the rotary filter, connect the foundation pit with the water source to achieve filtration of the water source;

[0003] The reason why the rotating frame of the rotary filter is installed first is because the rotating frame is the basic supporting structure of the entire rotary filter device; therefore, installing the rotating frame first can facilitate the operator to enter the foundation pit to perform assembly, welding, bolt connection and other work, thereby ensuring that its foundation part is firmly connected to the supporting structure in the foundation pit, and after the rotating frame is installed in the foundation pit, the staff can still move freely in and out of the foundation pit, which is conducive to the operator to detect the stability of the rotating frame installation, thereby ensuring the installation accuracy and firmness of the rotating frame; and after the installation of the screen frame and the rotating frame, placing them in the foundation pit will increase the overall weight of the equipment, making the overall lifting posing technical and safety risks, and after being hoisted into the foundation pit, the space in the foundation pit is reduced, making the operator's operating space in the foundation pit smaller, thereby affecting the operator's assembly, welding, bolt connection and other work in the foundation pit; thereby affecting the connection firmness of the prefabricated rotary filter in the foundation pit;

[0004] In the prior art, the mesh frame of a rotary filter is assembled by bolting the mesh frame to the rotating frame of the rotary filter. However, in water treatment projects, especially in large reservoirs, lakes, or deep well water treatment processes, a deeper foundation pit must be excavated to install the rotary filter in an ultra-deep environment. The deeper the foundation pit, the more mesh frames are required, which takes longer to install, reducing the installation efficiency of the rotary filter. This can even affect the start time of subsequent projects (such as pump station construction and pipeline installation), causing delays to the entire project plan.

[0005] In view of this, in order to overcome the above technical problems, the present invention proposes an installation structure for an ultra-deep rotary filter to solve the above technical problems. Summary of the Invention

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] like Figures 1 to 7 As shown, the installation structure of an ultra-deep rotary filter according to the present invention includes:

[0032] The frame 1 has two rotating shafts 11 distributed vertically below the frame 1; one of the rotating shafts 11 is rotatably connected to the frame 1; the other rotating shaft 11 is rotatably connected to the inner wall of the foundation pit; a driving disk 12 is provided inside the frame 1; the number of the driving disks 12 is two; the two driving disks 12 are fixedly connected to the rotating shaft 11; a driving motor 13 is installed on one side of the frame 1; the driving motor 13 is connected to the rotating shaft 11 through a transmission belt;

[0033] The frame 14 surrounds the two rotating shafts 11; the frame 14 includes a hinge plate 141 and a roller 142; the roller 142 is rotatably connected to the hinge plate 141; the driving disk 12 has an arcuate groove 121 on its surface; the roller 142 engages with the arcuate groove 121; a screen frame 2 is provided between the two driving disks 12 on the same surface of the rotating shaft 11; grooves 21 are provided on both sides of the screen frame 2; an insertion rod 211 is slidably connected to the groove 21; the insertion rod 211 is fixedly connected to the bottom of the groove 21 by a connecting spring 213; the side wall of the hinge plate 141 has a slot 143 that cooperates with the insertion rod 211;

[0034] The traction unit is installed inside the screen frame 2 ; the traction unit is used to pull the insertion rod 211 into the groove 21 .

[0035] As an embodiment of the present invention, the traction unit includes an electromagnetic sheet 212; the electromagnetic sheet 212 is embedded in the bottom of the groove 21;

[0036] During operation, the mesh frame 2 of the rotary filter in the prior art is assembled by fixing the mesh frame 2 to the rotary frame 14 of the rotary filter by bolts. However, in water treatment projects, especially in the treatment of water in certain large reservoirs, lakes, or deep wells, it is necessary to excavate a deeper foundation pit, so that the rotary filter is installed in an ultra-deep environment. The deeper the foundation pit, the more mesh frames 2 of the rotary filter are installed, making it take longer to install the mesh frames 2, thereby reducing the installation efficiency of the rotary filter. It may even affect the start time of subsequent projects (such as pump station construction and pipeline installation), thereby causing delays in the entire project plan.

[0037] To this end, the present invention provides an insertion rod 211, so that the user can use the electromagnetic sheet 212 to attract the insertion rod 211 into the groove 21, and then place the screen frame 2 between the frames 14, so that the insertion rod 211 of the screen frame 2 is aligned with the slot 143 of the frame 14, and then control the electromagnetic sheet 212 to be de-energized, so that the insertion rod 211 extends out of the groove 21 and is inserted into the slot 143, so that the frame 14 and the screen frame 2 are connected by plugging, without the need to use fasteners such as bolts for connection, greatly reducing the time for installing the screen frame 2 and improving the installation efficiency of the rotary filter; at the same time, no special tools are required to complete the installation and removal of the screen frame 2, thereby facilitating the user to replace and maintain the screen frame 2, which not only reduces downtime but also reduces the labor cost of replacing the screen frame 2;

[0038] In the initial state, an observation port is provided on one side of the frame 1; the driving disk 12 is set to be hexagonal, and the arc groove 121 is opened at the hexagonal position of the driving disk 12. The rotating shaft 11 located below is rotatably connected in the foundation pit, and two frames 14 are provided; the two frames 14 surround the driving disks 12 at both ends of the two rotating shafts 11 and are connected similarly to a belt drive; when the user needs to install the net frame 2 on the frame 14, the user first controls the electromagnetic sheet 212 to be energized, so that the electromagnetic sheet 212 can generate a magnetic attraction force on the insertion rod 211, so that the insertion rod 211 is adsorbed by the electromagnetic sheet 212 and squeezes the connecting spring 213 into the groove 21. Then the user puts the screen frame 2 into the frame 1 through the observation port of the frame 1, so that the screen frame 2 is placed between the two frames 14, so that the screen frame 2 is located between the hinge plates 141 of the two frames 14, and the grooves 21 on both sides of the screen frame 2 are aligned with the slots 143 of the hinge plates 141, and then controls the electromagnetic plate 212 to be de-energized, so that the insertion rod 211 extends out of the groove 21 and is inserted into the slot 143 under the push of the restoring force of the connecting spring 213, so that the screen frame 2 is connected to the hinge plates 141 of the frame 14 through the insertion rod 211; after one screen frame 2 is installed, the drive motor 13 is controlled to run so that the drive motor 13 can drive the screen frame 2 through the transmission belt. The rotating shaft 11 rotates, so that the rotating shaft 11 can drive the driving disk 12 to rotate, so that the driving disk 12 drives the arc groove 121 to rotate synchronously. Since the roller 142 is located in the arc groove 121, the driving disk 12 pushes the roller 142 through the arc groove 121 to drive the hinged plate 141 connected to it to move, so that the frame 14 rotates around between the two driving disks 12 on the same side of the two rotating shafts 11, so that the hinged plate 141 drives the screen frame 2 connected to it to rotate downward, so that the part of the frame 14 where the screen frame 2 is not installed is rotated to the observation port of the frame 1, so that the user can install the screen frame 2 on the frame 14 more conveniently. , until the installation of the net frame 2 is completed, the driving motor 13 is controlled to run, so that the driving motor 13 drives the frame 14 to drive the net frame 2 into the foundation pit; the net frame 2 filters the water source flowing into the foundation pit, so that the filtered aquatic plants and other impurities are intercepted by the net frame 2, and as the frame 14 drives the net frame 2 to move upward, the net frame 2 can drive the intercepted aquatic plants and other impurities out of the foundation pit. When the net frame 2 drives the aquatic plants and other impurities to the observation port of the rack 1, the user can use the cleaning device to remove the aquatic plants and other impurities intercepted on the net frame 2, so that the cleaned net frame 2 can be driven by the frame 14 to enter the foundation pit again to filter the water source.

[0039] As an embodiment of the present invention, the traction unit includes a traction rod 221; a strip groove 22 is provided on a side of the net frame 2 away from the rotating shaft 11; the traction rod 221 is slidably connected in the strip groove 22; a steel wire rope 222 is fixedly connected to one end of the traction rod 221 close to the bottom of the strip groove 22; the end of the steel wire rope 222 away from the traction rod 221 passes through the groove 21 and is fixedly connected to the insertion rod 211.

[0040] As an embodiment of the present invention, a storage groove 23 connected to the strip groove 22 is opened inside the screen frame 2; a sealing plate 231 is slidably connected inside the storage groove 23; the end of the sealing plate 231 away from the storage groove 23 is slidably connected to the inner wall of the strip groove 22.

[0041] As an embodiment of the present invention, the sealing plate 231 is connected to the bottom of the storage tank 23 via a fixing spring 232; the surface of the screen frame 2 is provided with a positioning groove 24 that communicates with the strip groove 22; the positioning groove 24 is internally threaded with a screw 241; the surface of the sealing plate 231 is provided with a circular hole 242 that cooperates with the screw 241;

[0042] During operation, the screen frame 2 is driven by the frame 14 to enter the foundation pit for water filtration for a long time, which causes the screen frame 2 to be in a humid environment for a long time, causing the electromagnetic sheet 212 to be in a humid environment for a long time. The humid environment can cause the metal part of the surface of the electromagnetic sheet 212 to corrode or oxidize, causing the moisture to penetrate into the insulation layer of the electromagnetic sheet 212, reducing its insulation performance. This can cause a short circuit or overload inside the electromagnetic sheet 212, increasing the risk of circuit damage, resulting in the electromagnetic sheet 212 being unable to function normally, thereby affecting the replacement and maintenance of the screen frame 2.

[0043] To this end, the present invention provides a traction rod 221, so that the user can pull the traction rod 221, so that the traction rod 221 pulls the insertion rod 211 through the steel wire rope 222 to squeeze the connecting spring 213 and enter the groove 21, thereby eliminating the need to use the electromagnetic sheet 212 to adsorb the traction rod 221. This not only reduces power consumption, but also allows the insertion rod 211 and the steel wire rope 222 to be used stably and normally in a humid environment. Furthermore, during long-term operation, the insertion rod 211 can still pull the traction rod 221 in and out of the groove 21 through the steel wire rope 222, thereby improving the practical application effect of the present invention.

[0044] In the initial state, the sealing plate 231 extends out of the storage groove 23 and blocks the strip groove 22, and the screw 241 passes through the circular hole 242 on the surface of the sealing plate 231 and is threadedly connected to the positioning groove 24. The user first rotates the screw 241 so that the lower end surface of the screw 241 passes over the sealing plate 231 and extends out of the positioning groove 24; since the sealing plate 231 and the bottom of the storage groove 23 are fixedly connected by the fixing spring 232, during the process of the sealing plate 231 being inserted into the circular hole 242, the fixing spring 232 in the storage groove 23 is stretched by the sealing plate 231. The screw 241 passes over the sealing plate 231 and extends out of the positioning groove 24, and the sealing plate 231 moves into the storage groove 23 under the pull of the restoring force of the fixing spring 232, so that the sealing plate 231 blocking the notch of the strip groove 22 is pulled into the storage groove 23, thereby making the strip groove 22 in the open state. Then the user pulls out the traction rod 221 in the strip groove 22. Because the cross-sectional shape of the traction rod 221 is set to be a square shape, the user can hold the traction rod 221 so that the user can pull the traction rod 221 away from the strip groove 22. The mesh frame 2 is moved in the direction of the groove bottom, so that the traction rod 221 pulls the insertion rod 211 through the steel wire rope 222 fixed thereto to squeeze the connecting spring 213 into the groove 21; the user can move the mesh frame 2 by pulling the traction rod 221, and then place the mesh frame 2 between the two frames 14, so as to avoid the insertion rod 211 extending out of the groove 21 hindering the mesh frame 2 from being inserted between the hinge plates 141 of the two frames 14, so as to ensure that the groove 21 of the mesh frame 2 is aligned with the slot 143 of the hinge plate 141, thereby facilitating the connection between the mesh frame 2 and the frame 14; and improving the installation of the rotary filter. Efficiency; and the setting of the sealing plate 231 is for the purpose of shielding the strip groove 22, thereby blocking gravel and other debris in the water source from entering the strip groove 22, and preventing gravel and other debris from clogging the strip groove 22, so that when replacing and maintaining the rotary filter, it is convenient for the user to pull out the traction rod 221 in the strip groove 22, so as to extend the pulling rod 211 out of the slot 143 to separate the screen frame 2 from the frame 14, and then facilitate the user to remove the rotary screen frame 2 for replacement and maintenance, thereby further improving the practical application effect of the present invention.

[0045] As an embodiment of the present invention, a slide groove 15 is provided on one side of the net frame 2; a filter screen 151 is slidingly and sealedly connected in the slide groove 15; a rectangular groove 16 is provided on the upper end wall of the slide groove 15; a blocking plate 161 is slidingly and sealedly connected in the rectangular groove 16; the blocking plate 161 is fixedly connected to the bottom of the rectangular groove 16 through a support spring 162.

[0046] As an embodiment of the present invention, an installation cavity 17 is opened inside the net frame 2; a rotating rod 171 is rotatably connected in the installation cavity 17; a glass fiber rope 172 is wrapped around the surface of the rotating rod 171; one end of the glass fiber rope 172 is fixedly connected to the rotating rod 171, and the other end is fixedly connected to the blocking plate 161.

[0047] As an embodiment of the present invention, one end of the rotating rod 171 is connected to an L-shaped rod 173; a square groove 174 is formed on the end of the L-shaped rod 173 near the rotating rod 171; the end of the rotating rod 171 near the L-shaped rod 173 is set to be square; the square end of the rotating rod 171 is slidably and sealedly connected to the square groove 174; the bottom of the square groove 174 is embedded with a magnet 175; the side wall of the screen frame 2 is formed with a connecting groove 25 that cooperates with the L-shaped rod 173;

[0048] During operation, when the screen frame 2 is used for a long time, the stainless steel metal filter 151 of the screen frame 2 will still be damaged due to wear. At this time, the user needs to replace the metal filter 151 of the screen frame 2. If the entire screen frame 2 is replaced, the replacement cost will be high. Therefore, by setting the filter 151 and the screen frame 2 to be slidingly connected, when replacing the filter 151, there is no need to disassemble and replace the entire screen frame 2, thereby reducing the replacement and maintenance costs, and further improving the practical application effect of the present invention.

[0049] When the user replaces the filter screen 151, he needs to first pull the traction rod 221 so that the traction rod 221 can pull the insertion rod 211 out of the slot 143, so that the screen frame 2 is no longer connected to the frame 14, and then lift the end of the screen frame 2 with the slide groove 15 to the upper end of the screen frame 2 close to it; so that the slide groove 15 is not blocked by the screen frame 2 contacted by the end; at this time, the user first pulls the L-shaped rod 173 so that the L-shaped rod 173 can extend out of the connecting slot 25, and at this time the L-shaped rod 173 drives the magnet 175 in the square slot 174 away from the square end of the rotating rod 171 until the rectangular end of the L-shaped rod 173 exposes the connecting slot 25, and at this time the round end of the L-shaped rod 173 is located in the connecting slot 25, and the rotating rod 171 is still located in the square slot 17 4, rotate the L-shaped rod 173 so that the L-shaped rod 173 can drive the rotating rod 171 slidably connected to the square groove 174 to rotate, so that the rotating rod 171 can pull the glass fiber rope 172 fixed thereto to be wound around the surface of the rotating rod 171 during the rotation, so that the glass fiber rope 172 can pull the blocking plate 161 to squeeze the support spring 162 into the rectangular groove 16, so that the slide 15 is opened, so that the blocking plate 161 no longer blocks the filter screen 151, and then the user pulls out the filter screen 151 from the end of the slide 15 close to the rectangular groove 16, and then inserts a new filter screen 151 into the slide 15 to complete the replacement of the new filter screen 151, and then there is no need to replace the entire screen frame 2, which greatly reduces the risk of rotating the filter screen. The replacement and maintenance costs are reduced; the practical application effect of the present invention is improved; and after the filter screen 151 is replaced, the end of the filter screen 151 close to the rectangular groove 16 just passes over the blocking plate 161; the user rotates the L-shaped groove in the opposite direction, so that the L-shaped groove drives the rotating rod 171 to rotate in the opposite direction, so that the rotating rod 171 rotating in the opposite direction can release the fiberglass rope 172 wrapped around its surface, so that the fiberglass rope 172 no longer generates tension on the blocking plate 161, so that the blocking plate 161 is removed and extends out of the rectangular groove 16 under the push of the restoring force of the support spring 162 and is tightly pressed against the bottom of the groove 15, so that the blocking plate 161 is in sliding contact with the end of the filter screen 151 close to the rectangular groove 16, so that the filter screen 151 is stuck in the blocking of the blocking plate 161. 173 is inserted into the sliding groove 15; then the user aligns the rotating L-shaped rod 173 with the connecting groove 25. Since the rotating rod 171 is made of iron material, the magnet 175 in the square groove 174 generates a magnetic attraction force on the rotating rod 171. Therefore, the magnet 175 drives the L-shaped rod 173 close to the rotating rod 171, so that the rotating rod 171 is inserted into the square groove 174, and the L-shaped rod 173 is inserted into the connecting groove 25, so that the L-shaped rod 173 will not be exposed in the connecting groove 25, thereby facilitating the user to place the screen frame 2 between the two frames 14. At this time, the filter screen 151 in the screen frame 2 can be replaced without replacing the entire screen frame 2, which greatly reduces the replacement and maintenance cost of the screen frame 2, and further improves the practical application effect of the present invention.
