Technical Field

[0001] The utility model relates to the technical field of oil and natural gas exploration and development, in particular to a cuttings drying box. Background Art

[0002] In oil exploration and development, it is necessary to measure the lithology and oil content of the formation. For this purpose, the collected and cleaned rock cuttings need to be dried to facilitate subsequent measurement work.

[0003] At present, there are two main methods for drying rock cuttings: natural sun drying and oven drying. Natural sun drying is easily affected by the weather, takes a long time, and is slow. Oven drying tends to cause heat to gather in a local area, causing the light oil in some rock cuttings to evaporate with the water due to excessive temperature, resulting in the loss of original oil content information and poor drying effect. Utility Model Content

[0004] The utility model provides a cuttings drying box, which is used to solve the problem in the prior art that it is difficult to achieve both high drying efficiency and good drying effect.

[0005] The utility model provides a rock cuttings drying box, comprising: a box body, which encloses a drying space and is provided with an exhaust hole; a connecting body, which is rotatably connected to the box body through a rotating shaft and is located in the drying space; a container for accommodating rock cuttings, which is installed on the connecting body; and a blowing device, which is installed in the drying space.

[0006] In one embodiment, the blowing device can form an airflow toward the connecting body, and the connecting body is provided with a plurality of first through holes for the airflow to pass through the connecting body.

[0007] In one embodiment, the exhaust hole is arranged on the first side wall of the box body, the first side wall is parallel to the connecting body, and the blowing device is located on a side of the connecting body away from the first side wall.

[0008] In one embodiment, it further comprises a heating device installed on the box body, and the heating device is located on a side of the connecting body away from the first side wall.

[0009] In one embodiment, the box body is provided with a transparent observation window, and the container is provided with a transparent observation shell.

[0010] In one embodiment, the container is provided with air holes, and the diameter of the air holes is smaller than the diameter of the rock cuttings to be dried.

[0011] In one embodiment, the connecting body includes a first connecting portion and a clamping jaw, the first connecting portion is connected to the rotating shaft, the clamping jaw is installed on the first connecting portion, and the container is clamped by the clamping jaw.

[0012] In one embodiment, the outer contour of the first connection part is circular, the axis of the first connection part is colinear with the axis of the rotating shaft, a plurality of clamping jaws are mounted on the first connection part, and the clamping jaws are evenly spaced along the circumferential direction of the first connection part.

[0013] In one embodiment, the rotating shaft is equipped with at least two parallel connecting bodies.

[0014] In one embodiment, the rotating shaft is arranged horizontally.

[0015] Compared with the prior art, the advantage of the present invention is that the rock cuttings are dried by drying, which has a higher drying efficiency than natural drying. Since the box body is provided with exhaust holes and a blowing device is provided in the drying space, it is beneficial for water vapor to be discharged from the box body, and high-temperature steam is prevented from accumulating inside the box body and increasing the temperature of the drying space. At the same time, the connection piece can be used to drive the container to rotate, so that the temperature of the rock cuttings in each area is relatively uniform, which avoids the volatilization of local rock cuttings oil and improves the drying effect of the rock cuttings. Therefore, the present application provides a rock cuttings drying box with a fast drying speed and better drying effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The utility model will be further described below in conjunction with the accompanying drawings.

[0028] See also Figure 1 and Figure 2 As shown, a cuttings drying box is provided in an embodiment of the utility model, which includes: a box body 1, the box body 1 encloses a drying space, and the box body 1 is provided with an exhaust hole 11; a connector 2, which is rotatably connected to the box body 1 through a rotating shaft 3, and the connector 2 is located in the drying space; a container 4 for accommodating cuttings, and the container 4 is installed on the connector 2; a blowing device 5, and the blowing device 5 is installed in the drying space.

[0029] The drying space surrounded by the box 1 can dry the rock cuttings in the container 4. Compared with natural drying, the temperature of drying heating is more stable, and the rock cuttings can be dried faster. In addition, a rotating shaft 3 is provided in the box 1. When the rotating shaft 3 rotates, it can drive the container 4 on the connector 2 to rotate. The position of the container 4 can be adjusted by rotating, so that the heat of each container 4 is more uniform, and the rock cuttings in individual containers 4 are prevented from volatilizing due to excessive temperature. At the same time, an exhaust hole 11 is opened on the box 1, and a blowing device 5 is provided in the drying space. The blowing device 5 can blow out the water vapor in the box 1 along the exhaust hole 11, so that the drying effect of the rock cuttings is better.

[0030] In the present application, the blowing device 5 is a fan. In other implementations, the blowing device 5 can also be configured as a jet device to achieve a blowing effect by jetting gas.

[0031] In some implementations, a filter screen may be provided at the exhaust hole 11, and the filter screen may be used to prevent external pollutants from entering the drying space through the exhaust hole 11. Specifically, the filter screen may be provided as a snap-fit ​​structure that snaps into the exhaust hole 11 in a one-to-one correspondence; the filter screen cover may also be attached to the surface of the box body, thereby covering the end of the exhaust hole 11. The specific installation method of the filter screen is not limited, as long as the filtering effect on the exhaust hole 11 can be satisfied. In addition, a water absorption unit may be provided at the filter screen, and the water absorption unit may be used to absorb water vapor to maintain the dryness and cleanliness of the inside of the box body 1.

[0032] See also Figure 1 and Figure 3 As shown, in some embodiments, the blowing device 5 can form an airflow toward the connecting body 2, and the connecting body 2 is provided with a plurality of first through holes 211 for the airflow to pass through the connecting body 2. By providing the first through holes 211 on the connecting body 2 and directing the blowing device 5 toward the connecting body 2, the airflow can pass through the connecting body 2 smoothly, thereby taking the water vapor generated by drying away from the container 4 installed on the connecting body 2.

Since the blowing device 5 is located on the side of the connector 2 away from the first side wall, an airflow from the blowing device 5 to the connector 2 and then to the first side wall can be formed in the box body 1, and the gas flow direction is relatively smooth, which can ensure the discharge effect of water vapor. Avoid water vapor accumulation inside the box body 1 due to poor air flow. In this application, since the connector 2 is vertically arranged, the exhaust hole 11 is arranged on the side of the box body 1 to ensure that the connector 2 is parallel to the first side wall. In other implementations, if the connector 2 is horizontally arranged, the exhaust hole 11 can also be arranged on the top surface or bottom surface of the box body 1.

[0034] See also Figure 1 and Figure 2 As shown, in some embodiments, the cuttings drying box further comprises a heating device 6 installed on the box body 1, and the heating device 6 is located on a side of the connecting body 2 away from the first side wall. That is, the heating device 6 and the blowing device 5 are located on the same side of the connecting body 2, and the gas heated by the heating device 6 can be blown into the container 4 provided in the connecting body 2 by the blowing device 5 to heat the cuttings.

Figure 2 As shown, the box body 1 is also provided with a movable door 7, which can be slidably pushed open or closed to facilitate the entry and exit of rock cuttings into and out of the box body 1.

[0037] See also Figure 4 As shown, in some embodiments, the container 4 is provided with a vent hole 42, and the aperture of the vent hole 42 is smaller than the diameter of the rock cuttings to be dried. During drying, the water vapor generated by the rock cuttings can escape from the container 4 through the vent hole 42, and because the aperture of the vent hole 42 is smaller than the diameter of the rock cuttings to be dried, the rock cuttings can be prevented from flying out of the container 4 during the rotation of the connector 2.

[0038] See also Figures 1 to 3As shown, the connecting body 2 includes a first connecting portion 21 and a clamping jaw 22, the first connecting portion 21 is connected to the rotating shaft 3, the clamping jaw 22 is installed on the first connecting portion 21, and the container 4 is clamped by the clamping jaw 22. The container 4 is clamped by the clamping jaw 22, so that the container 4 can be better fixed to the connecting body 2, and the container 4 is prevented from being separated from the connecting body 2 during the rotation of the connecting body 2.

[0039] See also Figure 3 As shown, in some embodiments, the outer contour of the first connection part 21 is circular, the axis of the first connection part 21 is colinear with the axis of the rotating shaft 3, a plurality of clamping jaws 22 are installed on the first connection part 21, and the clamping jaws 22 are evenly spaced along the circumferential direction of the first connection part 21. A plurality of containers 4 can be installed on the connecting body 2 to improve the efficiency of cuttings drying.

[0040] See also Figures 1 to 3 As shown, the rotating shaft 3 is equipped with at least two parallel connectors 2. The number of containers 4 arranged is increased, more cuttings can be dried at the same time, and the efficiency of cuttings drying is improved.

[0041] See also Figures 1 to 3 As shown, the rotating shaft 3 is arranged horizontally. When the rotating shaft 3 rotates, the height of each container 4 can be adjusted to prevent the container 4 from being in the bottom area where water vapor is more likely to accumulate for a long time, so that the effect of drying the cuttings is better.

[0042] See also Figure 3 As shown, an outer cover box 8 is also covered outside the box body 1, and an equipment installation space is enclosed between the outer cover box 8 and the box body 1. The drive motor of the rotating shaft 3 and the power device of the heating device 6 are both arranged in the equipment installation space, and the outer cover box 8 is provided with a plurality of second through holes 81 so that the gas exhausted from the exhaust hole 11 flows to the outside. In other embodiments, the outer cover box 8 may not be arranged outside the box body 1, and the motor can be directly installed on the outside of the box body 1.
