Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a filtering device for water conservancy projects. Background Art

[0002] Water conservancy projects are projects built to eliminate water disasters and develop and utilize water resources. Water is a valuable resource for human production and life, but water in its natural state cannot meet people's needs. Building water conservancy projects can control water flow, regulate and distribute water volume to meet people's needs for water resources in life and production.

[0003] In the process of mobilizing water resources in water conservancy projects, it is usually necessary to filter the water resources. However, the existing filtering devices clean the impurities after the filtering is completed, which will cause excessive accumulation of impurities in the filtering device and cause blockage, thereby affecting the normal operation of the device and greatly reducing the efficiency of water filtration. At the same time, the process of cleaning impurities is also very cumbersome. It is necessary to shut down the device and take out the filter inside the device for cleaning, which takes a lot of time and affects the progress of work.

[0004] Therefore, we need to develop a filtering device for water conservancy projects that can clean impurities while the device is running and can easily handle impurities. Utility Model Content

[0005] In order to overcome the shortcomings of the existing filtering device that the impurities cannot be cleaned in time and the impurity cleaning process is cumbersome, the utility model provides a novel filtering device for water conservancy projects that is convenient for cleaning impurities.

[0006] The technical scheme of the utility model is as follows: a filtering device for water conservancy projects, comprising a shell, an inlet pipe, an outlet pipe, a filter, a purification component, a screw, a limit rod, a connecting block, a scraper and a spring. A water inlet pipe is provided on the top left side of the shell, a water outlet pipe is provided on the right side of the shell, a filter is installed inside the shell, a screw is rotatably installed on the right side of the shell, a limit rod is fixedly installed on the left side of the shell, a connecting block is slidably installed at the front end of the shell, a scraper is connected between the screw and the limit rod through the connecting block, a scraper sleeve is provided with a plurality of springs, both ends of the spring are respectively connected to the scraper and the connecting block, and a purification component is provided in the shell.

[0007] In addition, it is particularly preferred that the purification component includes a storage box, a suction pump, a motor and a stirring rod, the motor is installed inside the shell, the output shaft of the motor is connected to the stirring rod, the storage box is installed on the right side of the top of the shell, the suction pump is installed on the left side of the top of the shell, and the storage box is connected to the interior of the shell through the suction pump.

[0008] In addition, it is particularly preferred that it also includes a screw, a collecting plate and a baffle, the collecting plate is installed on the rear side of the shell, the baffle is installed between the collecting plate and the filter screen in a pull-out manner, and the collecting plate is rotatably connected to the screw.

[0009] In addition, it is particularly preferred that a card plate is further included, and the card plate is slidably installed at the front end of the shell.

[0010] In addition, it is particularly preferred that a sealing gasket is further included, and a sealing gasket is arranged on the front side of the filter screen.

[0011] Furthermore, it is particularly preferred that the filter is provided with a handle.

[0012] The beneficial effect of the utility model is that the utility model rotates the screw rod, and under the traction of the limit rod, the scraper moves in contact with the filter screen to scrape off impurities.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0021] Example 1

[0022] A filtering device for water conservancy projects, such as Figure 1-Figure 6 As shown, it includes a shell 1, an inlet pipe 2, an outlet pipe 3, a filter 4, a purification component, a screw 6, a limit rod 7, a connecting block 8, a scraper 9 and a spring 10. The top left side of the shell 1 is provided with an inlet pipe 2, and untreated water flows into the filtering device from the inlet pipe 2. The right side of the shell 1 is provided with an outlet pipe 3, and the filtered water flows out from the outlet pipe 3. A filter 4 is installed inside the shell 1. The filter 4 can block large impurities in the water and make the impurities accumulate on the filter 4. The filter 4 is provided with a handle for easy extraction Out of the filter screen, a screw rod 6 is rotatably installed on the right side of the shell 1, a limit rod 7 is fixedly installed on the left side of the shell 1, a connecting block 8 is slidably installed at the front end of the shell 1, a scraper 9 is connected between the screw rod 6 and the limit rod 7 through the connecting block 8, and the scraper 9 is sleeved with a plurality of springs 10, and the two ends of the spring 10 are respectively connected to the scraper 9 and the connecting block 8. By rotating the screw rod 6, the scraper 9 can scrape on the filter screen 4. The shell 1 is provided with a purification component, which can remove impurities in the water that are difficult to remove by the filter screen.

[0023] like Figure 6 As shown, the purification component includes a storage box 15, a suction pump 16, a motor 17 and a stirring rod 18. The motor 17 is installed inside the shell 1, and the output shaft of the motor 17 is connected to the stirring rod 18. The storage box 15 is installed on the top right side of the shell 1, and the storage box 15 contains detergent. The suction pump 16 is installed on the top left side of the shell 1. The storage box 15 is connected to the inside of the shell 1 through the suction pump 16. The detergent enters the shell 1 through the suction pump 16 and mixes with water. The stirring rod 18 can fully mix the detergent and water.

[0024] When filtering water resources, the existing filtering devices clean up impurities after the filtering is completed, which can easily cause the filtering device to be blocked by too many impurities, affecting the subsequent filtering work. The process of cleaning impurities is also very troublesome. It is necessary to shut down the device and take out the filter screen inside the device to clean it, which affects the progress of the work. Therefore, we can use a new filtering device to filter water. First, untreated water flows into the device through the water inlet pipe 2, first passes through the filter screen 4 to filter out large impurities, and then the water is at the bottom of the shell 1. The detergent in the storage box 15 flows into the shell 1 through the suction pump 16 to mix with the water, and the motor 17 is started. The motor 17 drives the stirring rod 18 to rotate and stir the water so that the detergent and water are fully mixed to achieve the effect of purifying water. Then the outlet pipe 3 is unscrewed, and the cleaned water flows out from the outlet pipe 3. When scraping off the impurities on the filter screen 4, the screw 6 is rotated. Under the traction of the limit rod 7, the scraper 9 moves to fit the filter screen 4 to scrape off the impurities. The impurities will be accumulated on the filter screen 4 to the side close to the rear end of the shell 1.

[0025] Example 2

[0026] On the basis of Example 1, Figure 5 As shown, it also includes a screw 12, a collecting plate 13 and a baffle 14. The collecting plate 13 is installed on the rear side of the shell 1. The collecting plate 13 can collect impurities scraped from the filter screen 4. The baffle 14 is installed between the collecting plate 13 and the filter screen 4 in a pull-out manner. The baffle 14 can separate the filter screen 4 and the collecting plate 13. The collecting plate 13 is rotatably connected to the screw 12, and the collecting plate 12 is lifted by rotating the screw 12.

[0027] like Figure 2 As shown, a clamping plate 5 is also included. The front end of the shell 1 is slidably mounted with the clamping plate 5. The clamping plate 5 can fix the filter screen 4 in the shell 1. When the clamping plate 5 is lifted, the filter screen 4 can be pulled out.

[0028] like Figure 5 As shown, a sealing gasket 11 is also included. The front side of the filter screen 4 is provided with the sealing gasket 11, and the sealing gasket 11 can prevent water leakage from the shell.

[0029] When cleaning the impurities accumulated on the filter 4, it is only necessary to pull out the baffle 14, then rotate the screw 6, and continue to push the scraper 9 forward. The impurities on the filter 4 will accumulate on the collecting plate 13, and then insert the baffle 14 back and rotate the screw 12. The screw 12 drives the collecting plate 13 to move upward, so that the impurities on the collecting plate 13 can be easily cleaned. When the filter 4 is overused and needs to be replaced, it is only necessary to lift the card plate 5, pull out the filter 4 by the handle, and then install a new filter 4.
