Description

Technical Field

[0001] The invention relates to the technical field of pump room filtration, in particular to a height- and width-adjustable rotary filter screen. Background Art

[0002] The rotary filter is a water filtration device, which is mainly arranged on the water inlet side of the pump room. It consists of a drive device, a transmission system, a mesh plate and a chain, a guide rail, a flushing water system, an electric control system, etc. When water flows through the mesh surface, the dirt in the water flow is intercepted. The timed start makes the mesh plate rotate, and the rising side mesh plate lifts the dirt to the ground. Under the action of ≥0.5MPa pressure flushing water, the dirt flows into the designated location through the sewage collection tank for centralized treatment.

[0003] After long-term use, the rotary filter is easily stretched and deformed due to its own gravity and water pressure. The traditional method is to use the chain elongation alarm device to handle the alarm, and then wait for the maintenance personnel to lock and correct it. This method not only requires a long maintenance waiting time, but also the processing method is not timely. At the same time, the entire rotary filter is limited by the internal guide rail, resulting in a relatively simple laying structure, and its adaptability and functionality are very limited. At the same time, the surface cleaning effect of the filter can only rely on internal high-pressure flushing, and the flushing effect is very limited. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the current method for handling the tensile deformation of the rotating filter is not timely, and the laying structure is relatively simple, and the adaptability and functionality are very limited. At the same time, the surface cleaning effect of the filter can only rely on internal high-pressure flushing, and the flushing effect is very limited.

[0007] The electrically controlled internal guide bracket comprises an electrically controlled longitudinal guide frame installed on the lower surface of the upper frame and an electrically controlled bottom stabilizing frame slidably installed on the lower end of the electrically controlled longitudinal guide frame.

The second lower guide bracket is movably connected to the first lower guide bracket by inserting the bottom transverse adjusting screw into the interior of the internally threaded translation block.

[0014] The lower surface of the upper frame is provided with a sewage drain groove inside the external protective cover.

[0015] The beneficial effects of the present invention are:

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Figure 1 , Figure 2 , Figure 3 and Figure 4A height- and width-adjustable rotary filter is shown, comprising an upper frame 1 and a motor 2, wherein a transverse main shaft 3 controlled by the motor 2 is movably mounted inside the upper frame 1, an external driving sleeve 4 is axially sleeved and fixed on the outer side of the transverse main shaft 3, an externally mounted combined filter 5 is movably sleeved on the outer side of the external driving sleeve 4, a guiding and electrically controlled internal guide bracket 6 for lifting the externally mounted combined filter 5 is fixedly mounted on the lower surface of the upper frame 1, an external protective cover 7 is fixedly mounted on the upper surface of the upper frame 1, and a side-mounted dirt cleaning device 8 is installed inside the external protective cover 7.

[0030] Working principle: The motor 2 controls the rotation of the transverse main shaft 3, and then controls the rotation of the external drive sleeve 4.

[0031] The plate structure adopts the form of sleeve roller chain, which is composed of chain plate, roller, pin shaft, sleeve, etc. The pitch is generally 600, 500 and 400mm. The front water inlet rotary filter mostly adopts a pitch of 600mm, the side water inlet rotary filter mostly adopts a pitch of 500mm, and the bottom spray rotary filter mostly adopts a pitch of 400mm.

[0032] In the chain plate structure, there is no relative movement between the chain plate hole and the pin shaft and the shaft sleeve, so there is no wear and tear and the service life is long.

[0033] The chain roller is made of MC nylon, which has high strength, wear resistance, corrosion resistance, good elasticity and light weight. It can buffer and reduce vibration during operation and increase the service life of the working sprocket and guide rail.

[0034] The chain and mesh plate are connected by long bolts, and spacers are added between the inner and outer chain plates to ensure that the distance between the chain plates is balanced, ensuring that the chain plates rotate flexibly and increasing the service life of the chain plates. The connecting nuts are slotted nuts with stainless steel pins to prevent the nuts from loosening and falling off, making installation and maintenance easy.

[0035] The equipment can be operated manually or automatically for cleaning, and usually uses the automatic mode, which is equipped with a water level difference device.

[0036] Automatic operation can adopt a water level difference automatic control system, which can automatically start and stop operation according to the size of the water level difference, and add a timed start and alarm system to improve the reliability of equipment operation.

[0037] When the external combined filter 5 shows that the water level difference before and after the filter reaches 200mm, the flushing water pump can be automatically started in sequence → electric valve → water supply to the side-mounted cleaning device 8 → external combined filter 5 starts to work, and the external combined filter 5 starts to run at a low speed. When the water level difference before and after the external combined filter 5 decreases by 100mm, the system is automatically shut down, and the shutdown sequence is net → pump → valve. After the equipment runs for 30 minutes, if the water level difference before and after the external combined filter 5 does not drop to 100mm, the system can be automatically shut down.

[0038] When the water level difference before and after the external combined filter screen 5 reaches 300mm, the filter screen is automatically switched to the high speed gear.

[0039] When the water level difference before and after the external combined filter screen 5 reaches 400mm, an audible alarm is issued, wherein the alarm is provided with an audible cancellation button.

[0040] When the water level difference before and after the external combined filter 5 does not reach the starting water level difference for a long time, a timed start can be set, and the rotary screen is started every 8 to 12 hours, the rotary screen runs at a low speed, and is turned off after working for 15 to 30 minutes.

[0041] When the external combined filter screen 5 is stuck or overloaded, an audible alarm is sounded and the water pump and valve of the side-mounted cleaning device 8 are closed.

[0042] The control system can meet both manual and automatic operation modes.

[0043] In order to coordinate transmission and filtering, the external combined filter screen 5 includes a transmission chain 51 sleeved on both sides of the outer arc surface of the external driving sleeve 4 and a filter screen plate 52 movably installed between the transmission chain 51 through assembly shafts on both sides.

[0044] The filter screen plate 52 adopts a quick-detachable structural design and is installed and limited by lateral sliding installation. When the external drive sleeve 4 drives the transmission chain 51 to move upward and disengages from the lateral limit of the electrically controlled internal guide bracket 6, it can be quickly slid and disassembled laterally.

[0045] In order to facilitate the adjustment, the electrically controlled internal guide bracket 6 includes an electrically controlled longitudinal guide frame 61 installed on the lower surface of the upper frame 1 and an electrically controlled bottom stabilizing frame 62 slidably installed on the lower end of the electrically controlled longitudinal guide frame 61 .

[0046] In order to cooperate with the top translation adjustment, the electrically controlled longitudinal guide frame 61 includes a lateral adjustment guide rail 611 fixedly installed on the lower surface of the upper frame 1, an overhead translation screw 612 movably installed inside the lateral adjustment guide rail 611, an internally threaded translation block 613 threadedly sleeved on both sides of the overhead translation screw 612, and a first upper guide bracket 614 and a second upper guide bracket 615 of an inverted L-shaped structure respectively fixed on the side walls of the internally threaded translation block 613 on both sides.

[0047] The top translation screw 612 rotates to drive the internal thread translation blocks 613 on both sides to translate in opposite directions synchronously, and then adjust the distance between the first upper guide bracket 614 and the second upper guide bracket 615.

[0048] In order to cooperate with the bottom translation adjustment, the electrically controlled bottom stabilizing frame 62 includes a first lower guide bracket 621 slidably inserted in the lower end opening position of the first upper guide bracket 614, a second lower guide bracket 622 slidably inserted in the lower end opening position of the second upper guide bracket 615, and a bottom electrically controlled adjustment screw.

[0049] The bottom electrically controlled adjusting screw rod changes the gap between the first lower guide bracket 621 and the second lower guide bracket 622 by rotating, so as to coordinate with the upper part for synchronous adjustment to ensure the structural stability of the entire electrically controlled internal guide bracket 6.

[0050] In order to cooperate with monitoring and alarm, a lateral detection bracket 623 for monitoring the elongation state of the transmission chain 51 is fixedly installed on the outer side surface of the second lower guide bracket 622, and a chain elongation alarm device 9 cooperating with the lateral detection bracket 623 is installed on the upper surface of the upper frame 1.

[0051] The chain extension alarm device 9 consists of a detection frame fixed on the upper surface of the upper frame 1, a longitudinal adjustment rod installed in the detection frame through a spring sliding, a lateral touch sensor fixed on the inner wall of the detection frame and a detection pull rope connected to the upper surface of the lateral detection bracket 623 and the bottom of the longitudinal adjustment rod. When the transmission chain 51 is deformed and elongated, the second lower guide bracket 622 will also be squeezed downward, and then drive the lateral detection bracket 623 to pull the detection pull rope downward, and pull the longitudinal adjustment rod through the detection pull rope, and then the longitudinal adjustment rod will be squeezed to the lateral touch sensor on one side through the extrusion plate on its outer side, and then the lateral touch sensor controls the electrically controlled bottom stabilizing frame 62 at the lower end of the electrically controlled longitudinal guide frame 61 to extend outward, thereby ensuring the tension of the transmission chain 51.

[0052] In order to cooperate with the cleaning adjustment, the side cleaning device 8 includes a horizontal guide pipe 81 fixedly installed on the inner wall of the external protective cover 7, a high-pressure flushing nozzle 82 fixedly installed on the outer side of the horizontal guide pipe 81, an internal cleaning roller 83 movably installed on the inner wall of the external protective cover 7 and a lateral drive motor 84 fixedly installed on the outer side of the external protective cover 7.

[0053] In order to reduce costs, the lateral drive motor 84 can also be changed into a linkage gear set, and the external drive sleeve 4 and the internal cleaning roller 83 can be synchronously driven by the linkage gear set, which can further reduce energy consumption.

[0054] In order to cooperate with the elastic support, the lower ends of the inner sides of the first upper guide bracket 614 and the second upper guide bracket 615 are fixedly equipped with elastic limiting struts 10. The first upper guide bracket 614 is elastically assembled with the first lower guide bracket 621 through the elastic limiting struts 10, and the second upper guide bracket 615 is elastically assembled with the second lower guide bracket 622 through the elastic limiting struts 10.

[0055] The elastic limiting strut 10 controls the first lower guide bracket 621 and the second lower guide bracket 622 to be pressed downward by internal elastic extrusion, thereby ensuring the fit, and at the same time, the stretching length of the transmission chain 51 can be monitored in real time.

[0056] In order to cooperate with the bottom translation and extension, the bottom electrically controlled adjusting screw includes an internal threaded translation block 624 fixedly mounted on the surface of the first lower guide bracket 621 and a bottom transverse adjusting screw 625 mounted on the upper surface of the second lower guide bracket 622. The second lower guide bracket 622 is movably connected to the first lower guide bracket 621 by inserting the bottom transverse adjusting screw 625 into the interior of the internal threaded translation block 624.

[0057] The bottom horizontal adjustment screw rod 625 rotates to change the gap between the first lower guide bracket 621 and the second lower guide bracket 622, so that the width of the entire electric-controlled longitudinal guide frame 61 and the electric-controlled bottom stabilizing frame 62 can be increased, so that more lengths of the transmission chain 51 can be adapted, and the transmission chain 51 can be automatically adjusted to ensure the tension of the chain after being stretched and deformed, so as to ensure the running stability. It is convenient for maintenance personnel to rest in the later stage of maintenance.

[0058] In order to facilitate lateral sewage discharge, a sewage discharge groove 11 is provided on the lower surface of the upper frame 1 and located inside the outer protective cover.

[0059] The transverse main shaft 3 is controlled by the motor 2, and an external driving sleeve 4 is axially sleeved and fixed on the outer side of the transverse main shaft 3. The external driving sleeve 4 drives the external combined filter 5 to move. Then, when the external combined filter 5 moves, the high-pressure flushing nozzle 82 is started synchronously, and the internal cleaning roller 83 rotates at a high speed. The flipping direction of the internal cleaning roller 83 is opposite to the movement direction of the external combined filter 5. In this way, the impurities on the outer surface of the filter plate 52 can be quickly removed in cooperation with the high-pressure flushing nozzle 82.

[0060] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
