Description

Technical Field

[0001] The utility model relates to the field of heavy slag removers, in particular to an adjustable filtering system for heavy slag removers. Background Art

[0002] Heavy cleaner is a device that uses the centrifugal principle to remove impurities in slurry with a density greater than that of the slurry. Heavy cleaner works based on the different centrifugal forces of different substances during the rotation process. When the fluid enters the cylinder through the inlet, the centrifugal force is generated by the action of the rotating mechanism. The heavy matter is separated by the centrifugal force and settles to the bottom, while the clean fluid is discharged from the equipment through the separation plate.

[0003] The main body of the slag remover was originally designed as a cylinder, but around the 1950s, in order to improve the efficiency of slag removal, it was gradually improved to a cone design. This improvement has led to the widespread use of slag removers in the papermaking industry, and in subsequent development, a variety of models and series of products have emerged for different pulp types.

[0004] Before using the heavy slag remover, a filtration system may be needed to filter out heavy impurities in the slurry in advance. The filtration system can not only reduce the workload of the slag remover, but also improve the slag removal efficiency and reduce equipment wear. Application number: CN202120102565.6, discloses an adjustable filtration system for a heavy slag remover, which uses a filter plate to filter the raw pulp entering the heavy slag remover in advance, thereby reducing the work of the heavy slag remover, effectively preventing heavy impurities from wearing the equipment, and extending the service life of the equipment. However, when the device is in use, since the fluid will be filtered in advance, larger impurities will be trapped on the side of the filter screen away from the slag remover, and impurities similar in size to the filter mesh will accumulate on the filter screen, causing the filter screen to be blocked and need to be cleaned frequently. Although the device provides a certain cleaning force through a cleaning brush, the cleaning effect is generally poor and the filter screen is easily damaged during the cleaning process.

[0005] Therefore, it is necessary to provide an adjustable filtering system for a heavy slag remover to solve the above technical problems. Utility Model Content

[0024] The filter assembly 2 includes a filter block 21 disposed on the top of the body 1, a filter channel 22 is provided on the inner side of the filter block 21, a filter plate 23 is provided on the right side of the bottom of the inner wall of the filter channel 22, a connecting pipe 24 is connected to the right side of the filter channel 22, and the other end of the connecting pipe 24 is connected to the right side of the body 1;

[0025] When the fluid flows through the filter channel 22, the remaining impurities will be filtered by the filter plate 23 to avoid affecting the operation of the cleaner.

[0026] The primary filter assembly 3 includes a filter tube 31 connected to the top left side of the filter channel 22, a filter plate 32 is slidably arranged inside the filter tube 31, a liquid inlet pipe 33 is connected to the top of the left side of the filter tube 31, and grab ears 34 are arranged on the front and rear sides of the top of the filter plate 32.

[0027] The mesh of the filter sheet 32 ​​is larger than that of the filter plate 23, that is, the filter sheet 32 ​​filters larger impurities, and the provision of the grab ears 34 makes it easier to remove the filter sheet 32 ​​with larger impurities, and to some extent prolongs the filtering and cleaning cycle of the filter plate 23.

[0028] A sliding rod 25 is fixedly provided at the bottom of the inner wall of the filter channel 22 , and a cleaning brush 26 is provided on the peripheral side of the sliding rod 25 so as to slide up and down along its height direction. The right side of the cleaning brush 26 is tightly fitted to the left side of the filter plate 23 .

[0029] A rotating screw 27 is vertically rotatably provided at the bottom of the inner wall of the filter channel 22. The peripheral side of the rotating screw 27 is threadedly connected to the inner side of the cleaning brush 26. The top of the rotating screw 27 passes through the inner wall of the filter channel 22 and extends to the top of the filter block 21. A rotating handle 28 is provided at the top of the rotating screw 27.

[0030] The rotation of the rotating handle 28 can drive the rotation of the rotating screw rod 27, and then the rotating screw rod 27 cooperates with the sliding rod 25 to move the cleaning brush 26 upward. When the rotating handle 28 stops rotating, the torsion spring arranged at the bottom of the rotating screw rod 27 will drive the rotating screw rod 27 to rotate, thereby moving the cleaning brush 26 downward to clean the left side of the filter plate 23 and extend its service life.

[0031] A collecting box 29 is provided on the right side of the bottom of the filter block 21 . The top of the collecting box 29 is connected to a conical port 4 .

[0033] A sleeve 35 is provided at the bottom of the filter plate 32 , and a rotating rod 36 is vertically rotatably provided inside the sleeve 35 . The bottom end of the rotating rod 36 passes through the inside of the sleeve 35 and extends to the bottom thereof, and a rotating fan blade 37 is provided at the bottom end of the rotating rod 36 .

[0034] When the water flows down, it drives the rotating blades 37 to rotate, and then drives the rotating rod 36 to rotate, thereby driving the cleaning plate 38 on the top of the rotating rod 36 to clean the top of the filter plate 32, thereby extending the cleaning cycle of the filter plate 32.

[0035] The top end of the rotating rod 36 passes through the inner side of the sleeve 35 and extends to the top of the filter plate 32 . A cleaning plate 38 is provided at the top end of the rotating rod 36 and is tightly fitted to the top of the filter plate 32 .

[0036] The working principle of the adjustable filtering system for heavy slag remover provided by the utility model is as follows:

[0037] Step 1: When in use, the fluid that needs to be deslagging is first connected to the liquid inlet pipe 33 and discharged into the filter tube 31. The filter plate 32 is set to initially filter the larger impurities in the fluid. When the water flows down, it drives the rotating blades 37 to rotate, and then drives the rotating rod 36 to rotate, thereby driving the cleaning plate 38 on the top of the rotating rod 36 to clean the top of the filter plate 32, extending the cleaning cycle of the filter plate 32. The filter plate 32 can be easily taken out and cleaned through the setting of the two grab ears 34;

[0038] Step 2: The fluid after preliminary filtration will flow into the filter channel 22. When passing through the filter plate 23, the filter plate 23 will filter out some smaller impurities. These smaller impurities will fall into the collection box 29 at the bottom through the conical port 4 under the action of gravity. After the filter plate 23 has been used for a period of time, the rotation of the handle 28 drives the rotation of the screw rod 27, thereby driving the cleaning brush 26 to clean the left side of the filter plate 23, and clean some attached impurities so that they fall into the collection box 29.

[0039] Step 3: Since the fluid filtered by the filter plate 23 is filtered by the primary filter assembly 3, the filter plate 23 is less likely to be clogged than directly filtering the fluid, and its service life is extended. Finally, the filtered fluid will be discharged into the heavy slag remover body 1 through the connecting pipe 24.

[0040] Compared with the related art, the adjustable filtering system for heavy slag remover provided by the utility model has the following beneficial effects:

[0041] By arranging the primary filter component 3 in front of the filter component 2, since the mesh of the filter sheet 32 ​​is larger than the mesh of the filter plate 23, the filter sheet 32 ​​filters larger impurities, and the setting of the grab ear 34 facilitates the removal of the filter sheet 32 ​​with larger impurities, effectively avoiding possible damage to the filter plate 23 when cleaning larger impurities, and both components are provided with a dredging structure, which further improves the anti-clogging ability of the filter plate 23 and has a good use effect.
