[0020] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0021] Example:

[0022] like Figure 1-Figure 3 As shown, a water jet sand recovery system for a water jet cutting machine includes a water outlet structure, a box body 20 and a filtering structure arranged in the box body 20.

[0023] The working principle of the above technical solution is as follows:

[0024] When recycling water jet sand, the water jet sand with large particles of impurities and water is discharged to the box 20 through the water pipe 11, and the first motor 12 is started at the same time. The rotating screw 13 drives the movable block 16 to move horizontally relative to the screw 13 and the slide bar 15, and feeds at different positions of the coarse filter. The water jet sand and water mixed with small particles of impurities pass through the coarse filter, while the large particles of impurities move to the two lower parts of the coarse filter. During the screening process and after the screening is completed, the movable cover 23 is selectively opened according to the amount of large particles of impurities on the coarse filter, and the large particles of impurities are discharged from the impurity removal port 22. If the discharged large particles of impurities are still mixed with more water jet sand, they can be filtered twice; the subsequent fine filter plate 32 can screen the water jet sand twice, and the excess water and fine impurities pass through the fine filter plate 32 and are discharged from the first drain port 25, and the water jet sand falls obliquely on the fine filter plate 32 to the discharge port 24 for discharging and recovery.

[0025] In another embodiment, the top of the movable cover 23 is hinged to the outer wall of the box body 20, and can close the impurity removal port 22 by freely hanging down by its own weight. When a large number of large particles of impurities accumulate, the movable cover 23 is squeezed open, and a lock can also be set to manually open and close the movable cover 23.

[0026] In another embodiment, if Figure 1 As shown, a drying mechanism 40 is provided in the box body 20. The drying mechanism 40 can preliminarily dry the water jet sand, which is beneficial to the discharge of the water jet sand and the subsequent drying operation.

[0027] In another embodiment, if Figure 1 As shown, an inclined material guide plate 33 is provided in the box body 20 between the coarse filter plate 31 and the fine filter plate 32, and the lower part of the material guide plate 33 is arranged toward the higher part of the fine filter plate 32; the box body 20 is also provided with a pushing member at the higher part corresponding to the fine filter plate 32, and the pushing member includes a cylinder 34 and a pushing plate 35 arranged at the end of the cylinder 34, and the pushing direction of the pushing member is toward the lower part of the fine filter plate 32.

[0028] The water jet sand and water mixed with small particle impurities entering the fine filter plate 32 can be concentrated to a higher place, so that the water jet sand can be dried as much as possible by the drying mechanism 40 before falling to a lower place on the inclined fine filter plate 32 to the discharge port 24. If there is still accumulated water jet sand on the fine filter plate 32 after complete filtration on the coarse filter plate 31, the push plate 35 can be driven downward by the cylinder 34 to push the water jet sand out.

[0029] In another embodiment, if Figure 1As shown, a second drain outlet 26 is provided on the side wall of the box body 20 corresponding to the bottom of the higher part of the fine filter plate 32, an air inlet 27 is provided on the bottom side of the second drain outlet 26 of the box body 20, a water retaining plate 36 is provided on the inner side of the box body 20 between the second drain outlet 26 and the air inlet 27, and the water retaining plate 36 is inclined from high to low along the direction from the inside of the box body 20 to the second drain outlet 26, and the drying mechanism 40 is a hot air blower with horizontal wind direction, which is arranged at the air inlet 27 and is arranged toward the bottom side of the lower half of the fine filter plate 32.

[0030] Some of the water and small particles of impurities concentrated at the higher part of the fine filter plate 32 can be discharged from the second drain port 26. The water retaining plate 36 can divert the water and prevent the water from entering the hot air blower. The hot air blower can dry the water jet sand at the bottom through the fine filter and provide power for the water jet sand to fall, which is conducive to drying and facilitates the falling of the lower part of the water jet sand.

[0031] In another embodiment, if Figure 1 and Figure 4 As shown, a shield 37 is provided on the top side of the lower half of the fine filter plate 32. This can prevent the hot air blower from blowing the flowing water and some small particles of impurities to other positions in the box body 20 due to excessive wind force, thereby affecting the screening effect.

[0032] In another embodiment, if Figure 1-2 As shown, in order to prevent the water jet sand from accumulating between the lower part of the fine filter screen and the discharge port 24, a discharge platform 38 is provided between the lower part of the fine filter plate 32 and the discharge port 24, and a scraper mechanism 50 is provided on the discharge platform 38. The scraper mechanism 50 includes a rotating shaft and a scraper blade provided outside the rotating shaft. A second motor 51 driving the rotating shaft to rotate is provided on the box body 20, and a second mounting seat 28 supporting the second motor 51 is provided on the box body 20. The water jet sand can be scraped toward the discharge port 24 by starting the second motor 51 to rotate the scraper blade.

[0033] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
