Technical Field

[0001] This utility model relates to the field of engineering construction technology, specifically a slurry filtration device for high-pressure jet grouting pile construction. Background Technology

[0002] High-pressure jet grouting is a foundation treatment technology that uses high-pressure jet grout to forcibly mix cement slurry with the soil to form a solidified body. It is primarily used in engineering applications such as soft soil foundation reinforcement and seepage prevention curtains.

[0003] Filtration devices are needed when filtering slurry. Traditional filtration devices only use a single filter screen to filter the slurry. The filtered impurities accumulate on the filter screen for a long time and are difficult to clean, which can easily cause blockage and affect the subsequent filtration effect.

[0004] Therefore, a slurry filtration device for high-pressure jet grouting pile construction is proposed to address the above problems. Utility Model Content

A filter plate is slidably connected to the lower part of the box body. Slide plates are fixedly connected to both sides of the outer side of the filter plate. Both slide plates are slidably connected to the inner wall of the box body. A filter screen is provided inside the filter plate. A slot is provided inside the filter plate and on both sides of the filter screen. A mounting frame is detachably connected to the bottom of the filter plate.

[0008] Preferably, the linkage component includes a first synchronous pulley, which is fixedly connected to the upper outer side of the rotating rod. Both outer sides of the housing are rotatably connected to a rotating shaft via mounting plates. The top of each of the two rotating shafts is fixedly connected to a second synchronous pulley. The first synchronous pulley and the two second synchronous pulleys are respectively connected by two synchronous belts.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1-5 As shown, a slurry filtration device for high-pressure jet grouting pile construction includes a housing 1. A filter plate 3 is slidably connected to the lower part of the housing 1. Slide plates 4 are fixedly connected to both sides of the filter plate 3. Both slide plates 4 are slidably connected to the inner wall of the housing 1. A filter screen is provided inside the filter plate 3. A groove 5 is provided inside the filter plate 3 and on both sides of the filter screen. A mounting frame 6 is detachably connected to the bottom of the filter plate 3. A collection box 7 is fixedly connected to both sides of the mounting frame 6. A rotating rod 8 is rotatably connected to the top of the filter plate 3 through a fixed frame. A cleaning brush 9 is fixedly connected to the bottom of the rotating rod 8. A transmission assembly and a linkage assembly are provided inside the housing 1.

[0026] The transmission assembly includes a motor 10, which is fixedly connected to the inside of the housing 1 via a mounting bracket. The output end of the motor 10 extends to the bottom of the mounting bracket and is fixedly connected to the rotating rod 8. The linkage assembly includes a first synchronous pulley 11, which is fixedly connected to the upper part of the rotating rod 8. Rotating shafts 12 are rotatably connected to both sides of the housing 1 via mounting plates. Second synchronous pulleys 13 are fixedly connected to the top of each of the two rotating shafts 12. The first synchronous pulley 11 and the two second synchronous pulleys 13 are respectively connected by two synchronous belts 14. The linkage assembly also includes an eccentric wheel 15. 15 are fixedly connected to the bottom of the two rotating shafts 12 respectively. A sliding shaft 16 is fixedly connected to one side of the bottom of each of the two eccentric wheels 15. A sliding groove 17 is opened on one side of the top of each of the two sliding plates 4. The two sliding shafts 16 are slidably connected to the inside of the corresponding sliding groove 17. An installation cylinder 18 is fixedly connected to the bottom of the filter plate 3. A bolt 19 is rotatably connected inside the mounting bracket 6. The bolt 19 is threadedly connected to the installation cylinder 18. An inlet 21 is fixedly connected to the top of the box 1. A discharge port 22 is fixedly connected to the bottom of the box 1. A solenoid valve is installed inside the discharge port 22. A filter screen is installed on the outside of the collection box 7.

[0027] During operation, the slurry is poured into the interior of the box 1 through the feed inlet 21. The slurry can be filtered through the filter screen in the filter plate 3, and impurities are isolated on the top of the filter plate 3. The motor 10 is started to drive the rotating rod 8 and the first synchronous wheel 11 to rotate, so that the rotating rod 8 drives the cleaning brush 9 at the bottom to rotate, thereby cleaning the impurities on the top of the filter plate 3 and avoiding the situation where impurities accumulate for a long time and cause blockage of the filter screen.

[0028] Furthermore, during the rotation of the first synchronous wheel 11, the corresponding second synchronous wheel 13 and the rotating shaft 12 can be driven to rotate through the two synchronous belts 14. This causes the rotating shaft 12 to drive the bottom eccentric wheel 15 to rotate, and the eccentric wheel 15 in turn drives the bottom sliding shaft 16 to slide inside the sliding groove 17. This pushes the slide plate 4 and the filter plate 3 to perform lateral reciprocating motion, thereby driving the filter screen to vibrate. The vibration of the filter screen can drive the slurry on top to spread out quickly, thereby improving the filtration efficiency of the filter screen for the slurry. At the same time, with the cleaning brush 9, the filtered impurities can be driven into the interior of the trough 5 and then fall into the interior of the collection box 7 through the trough 5. The filter screen set outside the collection box 7 allows the slurry to pass through smoothly and isolates the impurities, preventing the slurry from accumulating inside the collection box 7 with the impurities. After the slurry is filtered, the solenoid valve is opened, and it can be discharged through the discharge port 22.

[0029] This device uses a reciprocating filter plate 3 to drive the filter screen to vibrate. The reciprocating filter plate 3, in conjunction with the vibration of the filter screen, can quickly spread the slurry, thereby improving the filtration efficiency of the filter screen. At the same time, the rotating cleaning brush 9, in conjunction with the horizontally reciprocating filter plate 3, can carry the impurities at the top into the inside of the trough 5, and then drop them into the inside of the collection box 7 through the trough 5. This achieves the cleaning and collection of impurities, effectively avoiding the problem that impurities can easily cause filter screen blockage due to long-term accumulation, thus affecting the filtration effect.

[0030] The box body 1 has inclined blocks fixedly connected to both sides inside and at the top of the filter plate 3. The box body 1 has a door 23 installed on the outside. The box body 1 has support legs 24 fixedly connected to both sides at the bottom.

[0031] With the above technical solution, after opening the box door 23, rotate the bolt 19. By unscrewing the bolt 19, the mounting frame 6 and the collection box 7 can be disassembled, which facilitates the centralized treatment of impurities in the collection box 7. After cleaning, the mounting frame 6 and the collection box 7 can be reinstalled by reversing the operation. The support leg 24 can effectively improve the stability of the device during operation.

[0033] Please see Figure 2 As shown in the first embodiment, as another implementation of this utility model, the upper part of the box 1 is symmetrically and fixedly connected with limit strips 20, and a filter grid 2 is slidably connected between the two limit strips 20.

[0034] During operation, the set filter grid 2 can perform initial filtration of the falling slurry, removing large impurities and thus effectively improving the effect of subsequent filtration of small impurities. By opening the box door 23, it is convenient for staff to centrally process the large impurities on the top of the filter grid 2.
