Technical field:
the invention relates to the field of geological drilling and logging engineering. In particular to a portable logging rock debris cleaning box.
The background technology is as follows:
drilling is an effective means for obtaining underground geological information, exploiting mineral resources such as underground oil and gas, etc. Rock debris will be continually produced as the drill bit drills through the formation and will be circulated back to the surface with mud drilling fluid. Geologists know the information of rock color and lithologic characteristics, structural characteristics, oiliness or mineralogy characteristics and the like of the stratum where the geologists are located by observing the rock fragments, and the work is called rock fragment logging. However, since the surface of the cuttings is coated with drilling mud, it must be cleaned and then observed. In order to obtain continuous subsurface geologic information, the cuttings must be collected and washed continuously at short intervals. Therefore, in a cuttings logging, cuttings cleaning is a tedious but very important task.
The rinsing method is the cleanest and quick method for cleaning the rock debris in the practical application process. And the size of the rock debris is still sorted by staff after the staff is required to distinguish the rock debris. Therefore, the rock debris cleaning device should be designed by adopting a rinsing method and a manual screening method.
The invention comprises the following steps:

Detailed Description
The invention is further described with reference to the accompanying drawings:
as shown in fig. 1, a box body 1 of the portable logging rock debris cleaning box is in a cubic box-shaped structure, the top surface of the box body is open, and two handles 9 are arranged outside the box body 1; the double-deck design, horizontal steel wire sorting net 2 separates box body 1 into box body, lower box body, and horizontal steel wire sorting net 2 is fixed connection with box body 1 all around, and horizontal steel wire sorting net 2 mesh diameter is great for select separately the detritus size. Large rock debris will remain on top of the horizontal wire sorting screen 2 for further screening by the staff. The box body 1 is provided with a box wall which is a steel wire filter screen, and the other three box walls and the box bottom of the box body 1 are wood plates or plastic plates. The steel wire filter screen is separated into an upper steel wire filter screen 7 and a lower steel wire filter screen 10 by a horizontal steel wire sorting screen, the upper steel wire filter screen 7 and the lower steel wire filter screen 10 are clamped and fixed with the box body 1 through corresponding clamping grooves 6, and the upper steel wire filter screen 7 and the lower steel wire filter screen 10 are provided with handles 8, so that the cleaning box is convenient to move.
The upper box body and the lower box body are both provided with a rock debris pushing mechanism for pushing out rock debris in the box. Each rock debris pushing mechanism consists of a scraping plate 3, two pull rods 4 and two pull rod sliding grooves 5, wherein the two pull rods 4 in the upper box rock debris pushing mechanism are connected with an upper steel wire filter screen 7, and the two pull rods 4 in the lower box rock debris pushing mechanism are connected with a lower steel wire filter screen 10. The method comprises the following steps: the two pull rod sliding grooves 5 in the upper box body are symmetrically arranged on the inner wall of the upper box body, the two pull rods 4 in the upper box body respectively penetrate through the corresponding pull rod sliding grooves 5, one ends of the two pull rods 4 in the upper box body are fixedly connected with the scraping plates 3 in the upper box body, and the other ends of the two pull rods 4 in the upper box body are fixedly connected with the upper steel wire filter screen 7; the two pull rod sliding grooves 5 in the lower box body are symmetrically arranged on the inner wall of the lower box body, the two pull rods 4 in the lower box body respectively penetrate through the corresponding pull rod sliding grooves 5, one ends of the two pull rods 4 in the lower box body are fixedly connected with the scraping plate 3 in the lower box body, and the other ends of the two pull rods 4 in the lower box body are fixedly connected with the lower steel wire filter screen 10.
The upper steel wire filter screen 7 is clamped and fixed with the clamping groove 6 in the upper box body, and the upper steel wire filter screen 7 is provided with a handle 8; the lower wire filter screen 10 is clamped and fixed with the clamping groove 6 in the lower box body, and the lower wire filter screen 10 is also provided with a handle 8. The clamping groove 6 is used for attaching the upper steel wire filter screen 7 and the lower steel wire filter screen 10 to the upper box body or the lower box body, and can prevent the upper steel wire filter screen 7 and the lower steel wire filter screen 10 from being opened during cleaning; the handle 8 is used for pulling the upper steel wire filter screen 7 or the lower steel wire filter screen 10 open, and meanwhile, the rock scraps in the upper box body or the lower box body are pushed out through the scraping plate 3, and the upper steel wire filter screen 7 or the lower steel wire filter screen 10 plays a role of a sliding door.
The pull rod sliding groove 5 is U-shaped, the notch of the pull rod sliding groove 5 of the upper box body is fixedly connected with the upper box body, and the pull rod sliding groove 5 is arranged at a position close to the upper steel wire filter screen 7; the notch of the pull rod sliding groove 5 of the lower box body is fixedly connected with the lower box body, and the pull rod sliding groove 5 is arranged at a position close to the lower steel wire filter screen 10. The pull rod sliding groove 5 is used for limiting the pull rod 4 to pull in the horizontal direction.
The meshes of the upper wire filter screen 7 and the lower wire filter screen 10 are designed to be 0.4-0.6cm, and optimally 0.5cm. The diameter of the mesh of the steel wire filter screen is smaller, so that water can be ensured to freely enter and exit when the rock debris is rinsed, and the rock debris is reserved in the upper box body or the lower box body.
When the invention is used, the upper steel wire filter screen 7 and the lower steel wire filter screen 10 on the side surfaces of the rock debris cleaning box are pushed into the clamping groove 6 so as to be attached to the box body 1 of the cleaning box. At the same time, the scraper 3 is pushed into the inside of the cleaning box under the connection of the pull rod 4. The rock scraps are poured into the box from the top opening of the box body 1 of the cleaning box, and single-particle rock scraps pass through the horizontal steel wire sorting net 2 to fall on the bottom of the box body, and adhered rock scraps are left on the horizontal steel wire sorting net 2 due to the large volume. The handle 9 of the box body is held, the whole rock debris cleaning box is placed in clear water, and rock debris is rinsed. The water in rinsing repeatedly goes in and out of the upper box body and the lower box body from the upper steel wire filter screen 7 and the lower steel wire filter screen 10. After the cleaning is completed, the cuttings cleaning box is taken out of the water, leaving the cleaned cuttings in the box. The staff can distinguish the large-volume rock fragments left on the horizontal steel wire sorting net 2, and if the large-volume rock fragments are formed by adhering a plurality of small-volume rock fragments, the large-volume rock fragments can be separated and then added with clear water again for rinsing. Finally, the handle 8 is pulled to drive the scraping plate 3 to take out the rock scraps left at the bottom of the horizontal steel wire sorting net 2 and the lower box body.
