Description

Technical Field

[0001] The invention relates to the technical field of pump room filter support, in particular to a rotary filter screen with a fast lifting support mechanism. 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] During use, the rotary filter screen will be affected by the water pressure on both sides, which is prone to extrusion and tensile deformation. Therefore, different specifications of internal limit frames need to be selected according to the size of different river channels. This results in general applicability and high cost. Summary of the invention

[0026] 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.

[0027] 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.

[0028] Figure 1 , Figure 2 and Figure 3 A rotary filter screen with a fast lifting support mechanism is shown, comprising a fixed beam 1 installed at the upper opening position of the river channel and a top frame 2 installed on the fixed beam 1, a driving motor 3 is installed inside the top frame 2, a driving belt 4 controlled by the driving motor 3 is arranged inside the top frame 2, a multi-section metal filter frame 5 is installed on the outside of the driving belt 4, a first inclined electric-controlled guide rail 6 and a second inclined electric-controlled guide rail 7 are fixedly installed on both sides of the driving motor 3 inside the top frame 2, a first electrically-controlled extendable support frame 8 is slidably installed inside the first inclined electric-controlled guide rail 6, and a second electrically-controlled extendable support frame 9 is slidably installed inside the second inclined electric-controlled guide rail 7.

[0029] Working principle: The first electrically-controlled extendable support frame 8 is slidably adjusted toward the lower left along the first inclined electrically-controlled guide rail 6, while the second electrically-controlled extendable support frame 9 is slidably adjusted toward the lower right along the second inclined electrically-controlled guide rail 7. At this time, the lower ends of the first electrically-controlled extendable support frame 8 and the second electrically-controlled extendable support frame 9 are squeezed on the inner bottom surface of the drive belt 4, and the two sides of the drive belt 4 are squeezed outward to fit the opening positions on both sides of the flow channel, and then squeezed outward through the expansion mechanism on the first electrically-controlled extendable support frame 8 and the second electrically-controlled extendable support frame 9, thereby improving the verticality and fit of the filter segment of the multi-segment metal filter frame 5 and improving the filtering effect.

[0030] In order to cooperate with the inclined guiding and sliding adjustment, the first inclined electrically controlled guide rail 6 and the second inclined electrically controlled guide rail 7 are both composed of an inclined guide rail 671, an external adjustment motor 672 fixed on the outer surface of the inclined guide rail 671 and a worm gear assembly 673 installed on the inclined guide rail 671.

[0031] The worm gear assembly 673 includes a worm axially fixed on the output shaft of the external adjustment motor 672 and a worm wheel meshing with the worm, and a driving gear is axially fixed on the side wall of the worm wheel.

[0032] In order to cooperate with flipping adjustment and stretching extrusion, the first electrically-controlled extension support frame 8 and the second electrically-controlled extension support frame 9 both include an inclined telescopic frame 891 slidably assembled inside the inclined guide rail 671, a flipping adjustment frame 892 movably installed inside the inclined telescopic frame 891, and a lateral support rod 893 and an electrically-controlled extrusion frame 894 for controlling the flipping adjustment frame 892.

[0033] The lateral support rod 893 controls the flip adjustment frame 892 to flip outward by stretching, and then the inner supporting force of the multi-stage metal filter frame 5 is increased by squeezing the electric-controlled squeezing frame 894 outward, thereby ensuring the fit with the inner wall opening of the flow channel.

[0034] In order to facilitate adjustment, a strip-shaped control tooth groove that matches the worm gear assembly 673 is opened on the side wall of the inclined telescopic frame 891, and an inner storage groove for assembling the flip adjustment frame 892 and the lateral support rod 893 is opened on the side wall of the inclined telescopic frame 891.

[0035] The driving gear meshes with the bar-shaped control tooth grooves for transmission.

[0036] The external adjustment motor 672 drives the worm gear assembly 673 to engage with the bar-shaped control tooth groove for transmission, and then drives the inclined telescopic frame 891 to slide and adjust along the inclined guide rail 671.

[0037] In order to cooperate with the adjustment of extrusion, the flip adjustment frame 892 is internally movably equipped with an electrically controlled adjustment screw 10, a first internal thread translation block 11 threadedly mounted on the electrically controlled adjustment screw 10, a second internal thread translation block 12, a third internal thread translation block 13, a fourth internal thread translation block 14, a first folding link 15 movably connected between the first internal thread translation block 11 and the second internal thread translation block 12, a second folding link 16 movably connected between the third internal thread translation block 13 and the fourth internal thread translation block 14, and a lateral positioning frame 17.

[0038] The electrically controlled adjusting screw 10 controls the first internal thread translation block 11 and the third internal thread translation block 13 to translate to one side, and the second internal thread translation block 12 and the fourth internal thread translation block 14 to translate to the other side by rotating, thereby controlling the first folding link 15 and the second folding link 16 to fold, contract and unfold, thereby controlling the adjustment of the lateral positioning frame 17.

[0039] In order to cooperate with the stretching adjustment, the back side of the lateral positioning frame 17 has a movable connection bracket, and the folding ends of the first folding link 15 and the second folding link 16 are movably connected to the lateral positioning frame 17 by being inserted into the movable connection bracket.

[0040] The first internal thread translation block 11, the second internal thread translation block 12, the third internal thread translation block 13, and the fourth internal thread translation block 14 are controlled to translate by rotating the electrically controlled adjusting screw 10, and then the first folding link 15 and the second folding link 16 are controlled to be squeezed and folded, and then the first folding link 15 and the second folding link 16 are used to control the lateral positioning frame 17 to extend and contract.

[0041] In order to reduce the lateral resistance, the lateral positioning frame 17 is movably equipped with an inner transmission wheel 18 .

[0042] The lateral positioning frame 17 is supported and limited by the inner side of the multi-stage metal filter frame 5 through the inner transmission wheel 18 .

[0043] In order to improve the limiting and guiding properties on both sides of the bottom, the bottom end of the inclined telescopic frame 891 is movably equipped with a bottom guide limiting wheel 19 that cooperates with the driving belt 4.

[0044] When the first electrically-controlled extendable support frame 8 and the second electrically-controlled extendable support frame 9 descend, the bottom guide limiting wheel 19 will be squeezed onto the drive belt 4, thereby supporting and limiting the two sides of the bottom of the drive belt 4, thereby squeezing the multi-section metal filter frame 5 on the outer side of the drive belt 4 to fit the inlet position on the side of the flow channel.

[0045] In order to monitor the lateral pressure and determine when maintenance is required, a pressure sensor controller 20 is provided at the connection end between the lateral positioning frame 17 and the inner transmission wheel 18 .

[0046] When the pressure of the pressure sensor controller 20 gradually increases to the set maximum pressure value, it means that the filter holes on the surface of the multi-segment metal filter frame 5 are blocked in large numbers and need to be cleaned and maintained. At this time, the pressure sensor controller 20 will control the drive motor 3 to start, driving the multi-segment metal filter frame 5 on the side with high pressure to lift upward, making it convenient for people to clean at the top frame 2 position.

[0047] In order to enhance the bottom supporting force after the descent, an electrically controlled sliding support stabilizing plate 21 is provided at the bottom of the first inclined electrically controlled guide rail 6 and the second inclined electrically controlled guide rail 7 .

[0048] The electrically controlled sliding support stabilizing plate 21 is composed of a sliding block slidably mounted on the bottom inclined surfaces of the first inclined electrically controlled guide rail 6 and the second inclined electrically controlled guide rail 7 and an inclined screw rod for controlling the sliding adjustment of the sliding block. The sliding block is sleeved on the inclined screw rod through an internal threaded assembly block on the surface and is threadedly assembled with the inclined screw rod.

[0049] When the first electrically-controlled extendable support frame 8 and the second electrically-controlled extendable support frame 9 descend, the electrically-controlled sliding support stabilizing plate 21 is controlled to extend downward, thereby increasing the supporting force on the bottom inclined surfaces of the first electrically-controlled extendable support frame 8 and the second electrically-controlled extendable support frame 9, thereby increasing the structural stability and firmness of the first electrically-controlled extendable support frame 8 and the second electrically-controlled extendable support frame 9.

[0050] 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.
