Description

Technical Field

[0001] This utility model belongs to the field of oilfield drilling technology, and more specifically, it relates to an integrated drilling mud treatment device. Background Technology

[0002] During oilfield drilling, a desanding and desilting machine is needed to separate the solid, liquid, and oil phases in the drilling mud. A vibrating screen separates the solid particles in the mud according to their size, allowing smaller particles and liquid to pass through the screen and enter a hydrocyclone. The hydrocyclone uses centrifugal force to cause the solid particles in the mud to settle in the centrifugal force field. The denser solid particles are thrown against the wall of the hydrocyclone and slide down the wall to the bottom outlet for discharge, while the less dense liquid and fine particles flow out from the central overflow outlet of the hydrocyclone into the storage area. By letting it stand or adding an appropriate flocculant, the oil phase floats on top, the water phase is in the middle layer, and the solid matter settles at the bottom, achieving three-phase separation.

[0003] For example, CN211814096U discloses an integrated sand and mud removal machine with adjustable screen box tilt angle, including a base, a support frame fixedly installed on the top of the base, a box movably installed on the top of the base inside the support frame, a first feed pipe fixedly installed on the top of the support frame, a first discharge pipe fixedly installed on the top of the support frame below the first feed pipe, a second feed pipe fixedly installed on the top right side of the support frame to the right of the first feed pipe, and a second discharge pipe fixedly installed on the top of the support frame on the opposite side of the first and second feed pipes. This integrated sand and mud removal machine with adjustable screen box tilt angle has high separation efficiency due to the cooperation of multiple sand removers. It can also adjust the sand and mud with different liquid contents accordingly, ensuring that the mixed mud and solution not separated by the sand removers can be recovered and separated again, thus saving resources and separation time.

[0004] Based on the above, after prolonged use, the screen mesh of the vibrating screen is prone to damage, affecting the screening effect of the mud. If the screen mesh is not replaced in time, larger solid particles may enter the hydrocyclone, causing the hydrocyclone to become blocked and affecting the normal operation of the processing device.

The vibrating screen mounting frame 2 is elastically connected to the upper part of the limiting mounting frame 1 by springs. Multiple fixed screens 3 are provided, and the multiple fixed screens 3 are evenly distributed and bolted to the lower part of the vibrating screen mounting frame 2. The material turning structure is provided on the lower side of the vibrating screen mounting frame 2. Multiple sliding screens 4 are provided, and the multiple sliding screens 4 are evenly distributed and slidably connected to the lower part of the vibrating screen mounting frame 2. Multiple connecting metal plates 5 are provided, and the multiple connecting metal plates 5 are respectively fixedly connected to the front and rear sides of the multiple sliding screens 4. Multiple sets of metal contact plates 6 are provided, and the multiple sets of metal contact plates 6 are evenly distributed and fixedly connected to the front and rear sides of the vibrating screen mounting frame 2. Multiple audible and visual alarms are evenly distributed and bolted to the front and rear sides of the limiting mounting frame 1.

[0026] The material turning structure includes a sliding connecting plate 201 and a transmission mounting shaft 202. There are two sliding connecting plates 201, which are slidably connected to the front and rear sides of the vibrating screen mounting frame 2, respectively. Both sides of the two sliding connecting plates 201 are fixedly connected with accordion dust covers. The transmission mounting shaft 202 is rotatably connected to the middle of the two sliding connecting plates 201.

[0027] The material turning structure also includes a sliding connecting block 205 and a position limiting screw 206. There are two sliding connecting blocks 205, which are slidably connected to the front and rear sides of the vibrating screen mounting frame 2, respectively. Both sliding connecting blocks 205 are rotatably connected to the transmission mounting shaft 202. There are two position limiting screws 206, which are rotatably connected to the front and rear sides of the vibrating screen mounting frame 2, respectively. The two position limiting screws 206 are threadedly connected to the two sliding connecting blocks 205 through threaded pairs.

[0028] The material turning structure also includes a transmission gear 203 and a transmission rack 204; there are two transmission gears 203, which are fixedly connected to the front and rear sides of the transmission mounting shaft 202 respectively; there are two transmission racks 204, which are fixedly connected to the front and rear sides of the vibrating screen mounting frame 2 respectively, and the two transmission racks 204 mesh with the two transmission gears 203 respectively.

[0029] The material turning structure also includes a reciprocating self-locking drive component 207 and an anti-clogging brush 208. There are two reciprocating self-locking drive components 207, which are bolted to the front and rear sides of the vibrating screen mounting frame 2 respectively.

[0030] The specific usage and function of this embodiment: The vibrating screen mounting frame 2 can determine the installation position of the fixed screen 3. The fixed screen 3 is used to perform preliminary screening of the mud. If the fixed screen 3 is partially damaged during the screening process, the sliding screen 4 will replace the fixed screen 3 to continue screening the mud, preventing larger solid particles from entering the hydrocyclone. During the screening process, the reciprocating self-locking drive 207 is activated, causing the output shaft of the reciprocating self-locking drive 207 to drive the position limiting screw 206 to rotate. When the position limiting screw 206 rotates, it will cause the sliding connecting block 205 to drive the sliding connecting plate 201 and the transmission mounting shaft 202 to move. At this time, the transmission gear 203, under the meshing action with the transmission rack 204, drives the transmission mounting shaft 202 and the anti-clogging brush 208 to rotate. The anti-clogging brush 208, which moves and rotates at the same time, can turn over the solid particles accumulated above the fixed screen 3, preventing the mesh of the fixed screen 3 from being blocked.

[0031] Example 2:

[0032] As attached Figure 3 To be continued Figure 5 As shown:

Multiple reset elastic elements 402 are provided, and the multiple sliding screens 4 are elastically connected to the vibrating screen mounting frame 2 through multiple reset elastic elements 402.

[0035] The specific usage and function of this embodiment are as follows: When solid particles begin to accumulate above the sliding screen 4, the weight of the solid particles causes the sliding screen 4 to be subjected to greater pressure, causing the sliding screen 4 to slide downwards. At this time, the connecting metal plate 5 will move downwards along with the sliding screen 4. After the connecting metal plate 5 contacts the corresponding metal contact plate 6, the control circuit of the audible and visual alarm will be activated, allowing the staff to promptly detect the damaged fixed screen 3. When the sliding screen 4 slides, the extension baffle 401 can block the connection between the sliding screen 4 and the vibrating screen mounting frame 2. After the solid particles above the sliding screen 4 are cleared, the reset elastic element 402 will push the sliding screen 4 back to its original position. At this time, the connecting metal plate 5 will no longer contact the metal contact plate 6, and the circuit of the audible and visual alarm will be disconnected.
