[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figures 1 to 5 This utility model provides a rock cuttings transportation and cleaning device, which includes:

[0028] A cleaning tank 1, and a support frame 2 mounted on the cleaning tank 1;

[0029] The main control box 9 is installed on one side of the cleaning tank 1;

[0030] A metal sand cage 3 is inclinedly mounted on the support frame 2, and a rotating rod 31 is rotatably installed inside the metal sand cage 3. A spiral blade 32 is fixedly installed at one end of the rotating rod 31 that extends into the metal sand cage 3. A power motor 33 for driving the rotating rod 31 to rotate is installed at the top of the metal sand cage 3. The power motor 33 is electrically connected to the main control box 9. A feed funnel 4 is embedded at the top of the bottom of the metal sand cage 3. A discharge pipe 5 is embedded at the bottom of the top of the metal sand cage 3. A sieve drying assembly 6 is installed on the washing tank 1 below the discharge pipe 5.

[0031] The spray assembly 7, used for washing rock cuttings, is installed on the metal sand cage 3. The spray assembly 7 includes a support rod 71, which is supported on the metal sand cage 3 and the feed funnel 4. Several spray pipes 72 are evenly installed on the side of the support rod 71 near the feed funnel 4. The top ends of the spray pipes 72 are all fixedly installed with a liquid inlet pipe 73. High-pressure nozzles 74 are installed at the bottom ends of the spray pipes 72. A water pump 8 is installed on one side of the cleaning tank 1. The water pump 8 is electrically connected to the main control box 9. The outlet end of the water pump 8 is connected to the liquid inlet pipe 73, and the inlet end of the water pump 8 is connected to the water supply pipeline.

[0032] The spiral blade 32 has several return holes 301 through it.

[0033] It should be noted that during use, the rock cuttings extracted from the well are fed into the metal sand cage 3 through the feed funnel 4. Then, the power motor 33 and the water pump 8 are started simultaneously. The power motor 33 drives the rotating rod 31 to rotate the spiral blades 32, thereby rotating and conveying the rock cuttings falling into the metal sand cage 3 upwards. During rotation, the water pump 8 introduces the cleaning liquid used to clean the rock cuttings into the flushing pipe 72 through the liquid inlet main pipe 73, and finally sprays it onto the metal sand cage 3 through the high-pressure nozzle 74, thereby rinsing the rock cuttings in the metal sand cage 3. Furthermore, when the flushing liquid is filled into the cleaning tank 1, and the liquid level in the cleaning tank 1 is higher than the bottom of the metal sand cage 3, the rock cuttings at the bottom are rolled and washed in the cleaning tank 1 when the spiral blades 32 rotate. This combination with flushing can improve the quality of rock cutting washing. After cleaning, the rock cuttings fall from the discharge pipe 5 onto the screening and drying assembly 6 along with the spiral blades 32 for screening and drying, which is convenient for subsequent separation and analysis.

[0034] In the embodiments of this utility model, please refer to Figures 1 to 5 The sieving and drying assembly 6 includes a support frame 61 mounted on the washing tank 1. The bottom end of the support frame 61 is connected to the washing tank 1 by several springs, and a vibration motor 62 is installed at the bottom end of the support frame 61. The vibration motor 62 is electrically connected to the main control box 9. Several screens 63 are installed at equal intervals inside the support frame 61.

[0035] Two sets of drying air ducts 64 are symmetrically installed on one side of the support frame 61. A protective net 65, an electric heating wire 66 and a blower 67 are installed on one side of the two sets of drying air ducts 64. The electric heating wire 66 and the blower 67 are electrically connected to the main control box 9.

[0036] It should be noted that when the screening and drying assembly 6 is in use, when the rock chips from the discharge pipe 5 are discharged onto the top screen 63, the vibration motor 62, the blower 67, and the heating wire 66 are started. In this way, the vibration motor 62 drives the support frame 61 to vibrate on the cleaning tank 1, which in turn drives several screens 63 to vibrate synchronously, thus separating the rock chips. During the vibration separation, the blower 67 blows the hot air heated by the heating wire 66 onto the screen 63, thereby drying the rock chips while screening them, which is convenient for later research.

[0037] It should also be noted that during installation, the lower middle part of the support frame 61 is secured in the slot at one end of the cleaning tank 1. The lower part of the support frame 61 is then secured with a tie spring, and the upper part is supported with a support spring. The support springs hold the support frame 61 in an inclined position with an angle between 20 and 30 degrees. This allows the debris to roll downwards along the screen 63 under its own weight when the vibrating motor 62 vibrates. To maintain this inclined screening state, the discharge speed of the discharge pipe 5 at the top of the support frame 61 needs to be controlled to prevent excessive load on the top of the support frame 61, which could cause the top of the support frame 61 to tilt downwards, resulting in debris backflow and affecting normal screening. The specific discharge speed is adjusted by regulating the speed of the power motor 33.

[0038] In this embodiment, the aperture of the several screens 63 decreases sequentially from top to bottom, which facilitates the sieving of rock fragments according to particle size.

[0039] In the embodiments of this utility model, please refer to Figures 1 to 5 The bottom of the cleaning tank 1 is fitted with a filter screen 11, and a drain pipe 12 is installed on one side of the cleaning tank 1, with the drain pipe 12 located below the filter screen 11.

[0040] It should be noted that a control valve is embedded in the drain pipe 12. The control valve is used to open and close the drain pipe 12. When liquid needs to be stored in the cleaning tank 1, the control valve closes the drain pipe 12. When liquid needs to be drained, the control valve opens the drain pipe 12. During the draining process, the filter screen 11 is used to filter and intercept impurities in the waste liquid.

[0041] The working principle of the rock cuttings transportation and cleaning device provided by this utility model is as follows:

[0042] In operation, drilling cuttings are fed into a metal sand cage 3 through a feed funnel 4. Simultaneously, a power motor 33 and a water pump 8 are started. The power motor 33 drives a rotating rod 31, which in turn rotates the spiral blades 32, thus rotating and conveying the rock cuttings falling into the metal sand cage 3 upwards. During rotation, the water pump 8 delivers cleaning liquid for cleaning the rock cuttings through a main inlet pipe 73 into a flushing pipe 72. Finally, the liquid is sprayed onto the metal sand cage 3 through a high-pressure nozzle 74, thus flushing the rock cuttings inside. Further, when the flushing liquid fills the cleaning tank 1, and the liquid level in the cleaning tank 1 is higher than the bottom of the metal sand cage 3, the spiral blades... When the spiral blade 32 rotates, the rock chips at the bottom are tumbled and washed in the washing tank 1. Combined with rinsing, this improves the quality of the rock chip rinsing. The washed rock chips are discharged from the discharge pipe 5 onto the screen 63 at the top, following the spiral blade 32. The vibration motor 62, blower 67, and heating wire 66 are started. The vibration motor 62 drives the support frame 61 to vibrate in the washing tank 1, which in turn drives several screens 63 to vibrate synchronously, separating the rock chips. During the vibration separation, the blower 67 blows hot air heated by the heating wire 66 onto the screens 63, thereby drying the rock chips while screening them, which is convenient for later research.

[0043] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0044] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
