DETAILED DESCRIPTION

[0035] 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.

[0036] Example 1, as Figure 1 and Figure 2As shown, a filtering device for the water inlet of a raw water filtration water intake pump station includes a shell 1, a reinforcing plate 2 is fixedly connected to the outer surface of the shell 1, a shell 2 5 is fixedly connected to the left upper end of the shell 1, and a filtering component 3 and a cleaning component 4 are provided on the inner surface of the shell 1.

[0037] During the implementation of this embodiment, the housing 1 and the housing 2 5 are placed in the water area of raw water. When the water pump station extracts raw water, the filter component 3 will perform multi-stage filtration processing on the impurities in the raw water, and add medicine to the filtered water. At the same time, the filtered impurities will be effectively cleaned through the cleaning component 4.

[0038] Specifically, in order to achieve multi-stage filtration of raw water, refer to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 9 In this embodiment, the filter assembly 3 includes a fixing plate 31 fixedly connected to the inner surface of the shell 1, a suction mechanism 32 is provided on the inner surface of the shell 1, a filtering mechanism 33 is provided on the inner surface of the fixing plate 31, a floating mechanism 34 is provided on the inner surface of the filtering mechanism 33, a dosing mechanism 35 is provided on the inner surfaces of the shell 1 and the shell 2 5, a knocking mechanism 36 is provided on the outer surface of the suction mechanism 32, and a filtering mechanism 37 is provided on the inner surface of the shell 1.

[0039] For further information, see Figure 3 and Figure 4 In this embodiment, the suction mechanism 32 includes two turbine shells 321 fixedly connected to the inner surface of the outer shell 1, the inner surfaces of the two turbine shells 321 are rotatably connected to the turbine rods 322, the inner surfaces of the two turbine shells 321 are fixedly connected to the connecting pipe 1 323, the inner surfaces of the two turbine shells 321 are commonly fixedly connected to the connecting pipe 2 324 fixedly connected to the outer shell 1, the outer surface of the connecting pipe 2 324 is fixedly installed with an electromagnetic valve 1 326, and the left end of the connecting pipe 2 324 is fixedly installed with a suction pump 325.

[0040] During the implementation process, when the water pump station extracts raw water, the pump 325 is started, so that the pump 325 generates suction in the connecting pipe 2 324, and introduces the water in the outer shell 1 into the turbine shell 321 through the connecting pipe 1 323, so that the turbine rod 322 can rotate under the impact of the water flow.

[0041] Secondly, the flow direction of water is controlled by the electromagnetic valve 1 326 so that the turbine rods 322 in the two turbine shells 321 can rotate independently.

[0042] The turbine rod 322 and turbine shell 321 mentioned above are both mature technical means and conventional technical designs in the existing technology, and will not be elaborated on in this solution.

[0043] For further information, see Figure 3 and Figure 6 In this embodiment, the floating mechanism 34 includes a connecting tube 1 341 fixedly connected to the hemispherical net 333 and the inner surface of the shell 1, a connecting tube 2 342 is slidably connected to the outer surface of the connecting tube 1 341, a leak block 343 is fixedly connected to the upper end of the connecting tube 2 342, an air bag 344 is fixedly connected to the outer surface of the leak block 343, and a solenoid valve 2 345 is fixedly installed on the inner surface of the connecting tube 1 341.

[0044] During implementation, when the shell 1 is placed in a set water area, the leakage block 343 on the connecting pipe 2 342 can always float on the water surface under the buoyancy provided by the air bag 344, and the other part of the leakage block 343 is always located below the water surface. It can follow the changes in the water level, maintain a stable water intake, effectively respond to water level fluctuations, ensure the stability of water flow during the filtration process, provide a continuous and balanced water source for subsequent filtration operations, ensure the efficient operation of the water intake pump station, improve the overall filtration effect and reduce the problem of unstable water intake caused by water level changes.

[0045] Secondly, the solenoid valve 345 can be used to control whether water is entering the equipment.

[0046] For further information, see Figure 3 and Figure 5 In this embodiment, the filtering mechanism 1 33 includes a hemispherical net 333 fixedly connected to the inner surface of the fixed plate 1 31, the inner surface of the hemispherical net 333 is fixedly connected to the fixed plate 2 331, the upper end of the fixed plate 2 331 is rotatably connected to the hemispherical block 332, the inner surface of the hemispherical block 332 is fixedly connected to the round rod 334 fixedly connected to the upper end of the turbine rod 322 located on the right, and the inner surface of the fixed plate 1 31 is fixedly connected to the connecting pipe 335.

[0047] For further information, see Figure 3 and Figure 9 In this embodiment, the filtering mechanism 2 37 includes an inclined plate 371 fixedly connected to the left and right parts of the inner surface of the shell 1, a wave plate 372 is fixedly connected to the inner surface of the inclined plate 371, a plurality of blocking plates 374 are fixedly connected to the upper end of the inclined plate 371, and a plurality of filtering holes 373 are opened at the upper end of the inclined plate 371.

[0048] During the implementation process, the water entering through the floating mechanism 34 will flow into the space formed by the hemispherical net 333 and the hemispherical block 332. Since the outer surface of the hemispherical block 332 is an arc surface, the water can be evenly distributed on the outer surface of the hemispherical block 332. The flow direction of the water is controlled by the electromagnetic valve 1 326, so that the turbine rod 322 located on the right rotates, and in the process of rotation, the hemispherical block 332 is driven to rotate, and the partition plate on the hemispherical block 332 can drive the raw water to splash and rebound on the inner surface of the hemispherical net 333, so that large particles in the water can be retained on the inner surface of the hemispherical net 333 under the action of the rebound. The water after preliminary filtration will fall on the upper end of the fixed plate 1 31 through the hemispherical net 333, and fall on the inclined plate 371 and the wave plate 372 through the connecting pipe 3 35 under the action of gravity. At this time, the water will be In the groove at the intersection of 71 and the wave plate 372, as the water continues to increase, the water will flow to the right and pass through the filter holes 373 in sequence during the flow, so that the filter holes 373 can filter the debris one by one according to the size of the aperture, and the filtered impurities are retained in the space formed by the inclined plate 371 and the blocking plate 374. The filtered water flows step by step under the action of gravity, passes through the intersection area of the inclined plate 371 and the wave plate 372, and is filtered step by step through the filter holes 373 with different apertures, separating the impurities according to size and retaining them in a specific space, which can effectively remove impurities in the water and achieve higher filtration accuracy through step-by-step filtration. At the same time, the anti-impact mechanism can reduce the clogging of the filter net, improve the filtration efficiency and reliability of the device, and realize multiple filtration operations on a filter plate, thereby reducing the use cost and maintenance.

[0049] Secondly, after multi-stage filtration, the water will enter the bottom of the shell 1 through the concave holes on the inclined plate 371.

[0050] The apertures of the filter holes 373 described above gradually decrease along the tilting direction, while the apertures of the filter holes 373 at the same location are the same.

[0051] Example 2, specifically, in order to filter the granular calcium chloride in the water, refer to Figure 3 and Figure 7 In this embodiment, the dosing mechanism 35 includes a circular cover 351 fixedly connected to the inner surface of the shell 1, the inner surface of the circular cover 351 is rotatably connected to the screw rod 352, the outer surface of the right turbine rod 322 and the outer surface of the screw rod 352 are fixedly connected to the gear set 1 353, the inner surface of the shell 2 5 is fixedly installed with a hopper 355, and the inner surface of the hopper 355 and the inner surface of the circular cover 351 are fixedly connected to the connecting pipe 3 354.

[0052] For further information, see Figure 3 and Figure 8In this embodiment, the knocking mechanism 36 includes a fixed rod 361 fixedly connected to the outer surface of the right turbine rod 322, and the inner surface of the fixed rod 361 is rotatably connected to the spherical rod 362. The front ends of the fixed rod 361 and the spherical rod 362 are jointly fixedly connected to a spring sheet 363.

[0053] During the implementation process, the right turbine rod 322 rotates under the transmission action of the gear set 1 353, driving the screw rod 352 to rotate in the circular cover 351, and then the granular calcium chloride in the hopper 355 falls into the inner cavity of the circular cover 351 through the connecting pipe 3 354. Under the action of the extruded spiral conveyor, the granular calcium chloride falls through the pipe to the bottom of the shell 1 and mixes with the filtered water to disinfect the purified water.

[0054] Secondly, the turbine rod 322 on the right side will drive the spherical rod 362 on the fixed rod 361 to rotate during the rotation process. At the same time, the connecting pipe three 354 is located within the rotation range of the spherical rod 362, so that the spherical rod 362 knocks and vibrates the connecting pipe three 354 through the deformation force of the spring sheet 363 during the rotation process, avoiding the connecting pipe three 354 and the hopper 355, realizing the automatic delivery and mixing of granular calcium chloride, thereby effectively improving the water purification effect.

[0055] The screw rod 352 and the circular cover 351 described above constitute a screw conveyor in the prior art.

[0056] The hopper 355 mentioned above is a mature technical means and equipment in the prior art. In this solution, the top of the hopper 355 can be opened and has good sealing performance.

[0057] Example 3: Specifically, in order to clean up the debris under multi-stage filtration, refer to Figure 3 、 Figure 10 、 Figure 11 and Figure 12 In this embodiment, the cleaning component 4 includes a slide plate 41 fixedly connected to the front part of the inner surface of the shell 1, the inner surface of the slide plate 41 is provided with a cleaning mechanism 42, the outer surface of the round rod 334 is provided with a scraping mechanism 43, the inner cavity of the shell 2 5 is fixedly installed with a collection frame 1 44, and the inner surface of the shell 1 is fixedly installed with a collection frame 2 45.

[0058] For further information, see Figure 11 In this embodiment, the scraping mechanism 43 includes two arc-shaped plates 431 fixedly connected to the outer surface of the round rod 334. The upper end of the second fixed plate 331 passes through and extends to the left end of the shell 1 and is fixedly connected to a fourth connecting pipe 432. The inner surface of the fourth connecting pipe 432 is fixedly installed with a third solenoid valve 433.

[0059] During the implementation process, the round rod 334 will drive the arc plate 431 to rotate and scrape the inner surface of the hemispherical net 333 during rotation, so that the arc plate 431 can clean up the large particles of debris that are retained, thereby preventing the hemispherical net 333 from being blocked. The cleaned debris will fall on the upper end of the fixed plate 2 331, and the solenoid valve 3 433 can be activated to allow the debris to fall into the connecting pipe 4 432 under the rotation of the arc plate 431, and finally reach the collection frame 1 44.

[0060] The solenoid valve 1 326 , the solenoid valve 2 345 and the solenoid valve 3 433 mentioned above are all mature control technology means and equipment in the existing technology, and this solution will not further elaborate on their internal structure, principles and connection methods.

[0061] For further information, see Figure 3 and Figure 10 In this embodiment, the cleaning mechanism 42 includes a reciprocating rod 421 that is slidably connected to the inner surface of the slide plate 41, and a scraper 423 that is slidably connected to the inner surface of the slide plate 41 is slidably connected to the outer surface of the reciprocating rod 421. The outer surface of the turbine rod 322 on the left and the outer surface of the reciprocating rod 421 are jointly fixedly connected to a gear set 2 422. Two spring telescopic rods 424 are fixedly connected to the front of the inner surface of the shell 1, and the rear ends of the two spring telescopic rods 424 are jointly fixedly connected to a placement plate 425.

[0062] During implementation, when it is necessary to clean the debris retained on the filter mechanism 2 37, the solenoid valve 1 326 is controlled to allow the pumped water to enter the turbine housing 321 located on the left, driving the turbine rod 322 located on the left to rotate, and the reciprocating rod 421 is driven to rotate under the transmission action of the gear set 2 422. Since the reciprocating rod 421 and the scraper 423 are slidingly connected, the scraper 423 can slide on the inner surface of the slide plate 41 and clean the debris retained by the inclined plate 371 and the wave plate 372. When the scraper 423 moves forward, the protrusion at the front end will push the placement plate 425 to move forward, so that the spring telescopic rod 424 is in a compressed state, and then the cleaned debris will be directly pushed into the collection frame 2 45, automatically and efficiently cleaning the retained large particles of debris, avoiding clogging of the filter screen, ensuring the stability of the filtration efficiency, and the cleaned debris is collected and discharged, reducing the frequency of manual cleaning and maintenance costs.

[0063] The reciprocating rod 421 and the scraper 423 constitute a ball screw mechanism in the prior art.

[0064] The gear set 1 353 and the gear set 2 422 mentioned above are both composed of two bevel gears.

[0065] Working process: When in use, water is stably fed in through the floating mechanism 34, and the raw water is subjected to multi-stage filtration operations under the action of the filtering mechanism 1 33 and the filtering mechanism 2 37. Then, during the suction process through the suction mechanism 32, the dosing mechanism 35 and the knocking mechanism 36 can add medicine to the filtered water for disinfection, and the cleaning mechanism 42 and the scraping mechanism 43 can also automatically clean the filtered debris.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
