[0031] The drilling fluid additive is used in cooperation with the drilling mud in the drilling process to improve the effect of the drilling mud and facilitate exploitation. The diameter of the additive needs to be controlled and sieved during production, and a special sieving device needs to be used for sieving.

[0032] In the related art, when the screen needs to be disassembled, the control rod needs to be pressed downward to make the adjusting block move downward. The sliding block on one side of the adjusting block slides in the sliding groove to drive the two moving blocks away, which can release the fixation of the fixed block, so as to disassemble the screen. However, the existing device is provided with multiple adjusting rods for fixation, multiple adjusting rods need to be pressed at the same time to make the moving blocks move away, so that the screen can be completely disassembled. Multiple workers are needed to cooperate to complete the disassembly, and the disassembly efficiency is low.

[0033] In order to solve the problems in the related art to some extent, the embodiment of the present application provides a screening device for drilling fluid additive production. When it is necessary to screen the drilling fluid additive, first, the vibration motor 12 is connected with an external power supply, and then the vibration motor 12 is started to make the vibration screen body 11 vibrate, and at the same time, the additive is poured from the top of the vibration screen body 11 to be screened through the screen mesh 13 to obtain particles of a suitable size. After the screening is completed, the screen mesh 13 needs to be disassembled for cleaning. The rotating rod 23 needs to be gripped and rotated to make the gear 24 mesh with the rack 28. In the process of rotation of the gear 24, the rack 28 moves and drives the two moving blocks 26 to approach. At the same time of approaching, the spring 27 is pulled to stretch, and at the same time, the inserting rod 25 is pulled to retract into the inside of the horizontal plate 21 and disengage from the positioning block 22 to release the restriction on the horizontal plate 21. Then, the horizontal plate 21 is pulled to drive the screen mesh 13 to be extracted from the inside of the vibration screen body 11.

[0034] The present application will be described below in combination with the drawings and with reference to specific embodiments:

[0035] The embodiment of the present application provides a screening device for drilling fluid additive production. The screening device comprises a vibration screen body 11, a vibration motor 12 arranged on one side of the vibration screen body 11, a screen mesh 13, a fixed assembly 2 arranged on one side of the screen mesh 13, a horizontal plate 21 arranged on one side of the screen mesh 13, a positioning block 22 arranged on the outer side wall of the vibration screen body 11, a rotating rod 23, a gear 24, an inserting rod 25, a moving block 26, a spring 27, a rack 28, a limiting assembly 3 arranged on one side of the screen mesh 13, a rectangular shell 31, a bolt 32, a threaded block 33, a connecting rod 34, and a clamping block 35.

[0036] Specifically, the model of the vibration motor 12 is YZU, and the principle of the vibrating screen is to use the reciprocating rotational vibration generated by the vibration exciter. Specifically, the vibrating screen generates vibration through the vibration exciter, so that the screen surface generates reciprocating rotational vibration. The vibration trajectory is circular in the horizontal plane and elliptical in the vertical plane. By adjusting the excitation force of the upper and lower rotating weights, the amplitude can be changed. By adjusting the spatial phase angle of the upper and lower weights, the curve shape of the screen surface movement trajectory can be changed, thereby changing the movement trajectory of the material on the screen surface.

[0037] Different types of vibrating screens have different working principles. For example, the circular vibrating screen generates circular motion through a cylindrical eccentric shaft exciter, and is suitable for product classification in mining, building materials, transportation, energy, chemical industry and other industries. The ultrasonic vibrating screen converts electrical energy into high-frequency electrical energy, inputs the ultrasonic transducer, and makes it become mechanical vibration, so as to realize efficient screening and net cleaning, and is especially suitable for processing materials with strong adsorption and easy agglomeration.

[0038] When the drilling fluid additive needs to be screened during use, first, the vibration motor 12 needs to be connected with the external power supply, and then the vibration motor 12 is started to make the vibrating screen body 11 vibrate. At the same time, the additive is poured from the top of the vibrating screen body 11 to screen out particles of appropriate size through the screen 13. After the screening is completed, the screen 13 needs to be disassembled and cleaned. The rotating rod 23 needs to be gripped and rotated to make the gear 24 mesh with the rack 28. During the rotation of the gear 24, the rack 28 moves and drives the two moving blocks 26 to approach. At the same time of approaching, the spring 27 is pulled to stretch, and the plug rod 25 is pulled to retract into the inside of the horizontal plate 21 and disengage from the positioning block 22 to release the restriction on the horizontal plate 21. Then, the horizontal plate 21 is pulled to drive the screen 13 to be extracted from the inside of the vibrating screen body 11.

[0039] After the screen 13 is installed, the screw 32 can be rotated to screw with the threaded block 33, and drive the threaded block to move to the inner wall of the rectangular shell 31. During the movement, the connecting rod 34 is pushed to rotate, and the clamping block 35 is pushed to extend from the inside of the rectangular shell 31 to limit the position of the rectangular shell 31.

[0040] In some embodiments, the fixing assembly 2 further comprises: a rotating handle 231 arranged at one end of the rotating rod 23.

[0041] The rotating handle 231 is designed to facilitate gripping, and the groove on the rotating handle 231 can increase the friction force during gripping.

[0042] In some embodiments, the fixing assembly 2 further comprises: a cone 251 arranged at one end of the plug rod 25.

[0043] The pointed end of the cone 251 can make it easier to insert the rod 25 into the positioning block 22.

[0044] In some embodiments, the fixing assembly 2 further comprises a stopper 281 arranged at one end of the rack 28.

[0045] The stopper 281 can prevent the rack 28 from disengaging from the gear 24 during the engagement of the gear 24 and the rack 28.

[0046] In some embodiments, the fixing assembly 2 further comprises a protrusion 29 symmetrically arranged on the inner side wall of the vibrating screen body 11.

[0047] The protrusion 29 can stabilize the position of the screen 13 in the vibrating screen body 11 and reduce the up-and-down movement during vibration.

[0048] In some embodiments, the connecting rod 34 and the clamping block 35 are each provided with four groups.

[0049] The four groups can provide better limiting effect.

[0050] In some embodiments, the limiting assembly 3 further comprises a sliding groove 36 arranged on the top of the clamping block 35, and a sliding block 37 inserted into the sliding groove 36 and connected to the inner side wall of the rectangular shell 31.

[0051] The sliding block 37 and the sliding groove 36 can make the clamping block 35 more stable during movement and prevent it from disengaging from the inner side wall of the rectangular shell 31.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in the present specification.
