By the foregoing solution, the problem that in the prior art, the inner wall of the mixing tank 101 for the production of petroleum drilling aids is mostly cleaned manually with slow cleaning efficiency is solved. It can be understood that the foregoing solution can be used in the structure of the mixing device for the production of petroleum drilling aids.

[0023] For this specific embodiment, the mounting frame 102 is arranged on one side of the mixing tank 101. The top of the mounting frame 102 is provided with the hydraulic cylinder 103. The hydraulic cylinder 103 is located above the center of the mixing tank 101. The output end of the hydraulic cylinder 103 is provided with the mounting plate 104. The mounting plate 104 is provided with the driving motor 105. The output end of the driving motor 105 is provided with a stirring shaft 118. The stirring shaft 118 is provided with stirring blades 119. After adding various raw materials for the production of petroleum drilling aids into the mixing tank 101, start the hydraulic cylinder 103 to drive the mounting plate 104 to descend, so that the stirring blades 119 are located inside the mixing tank 101. Start the driving motor 105, and drive the stirring blades 119 to rotate through the stirring shaft 118, thereby completing the mixing of various raw materials by using the stirring blades 119.

[0024] Among them, a rotating disk 107 is rotatably arranged on the upper surface of the mounting base 106. A rotating assembly is arranged inside the mounting base 106. The output end of the rotating assembly is in mechanical transmission with the rotating disk 107. The mixing tank 101 is installed on the upper surface of the rotating disk 107. An extension arm 108 is further arranged at the top of the mounting frame 102. An electric push rod 109 is arranged on the extension arm 108. The output end of the electric push rod 109 is provided with a fixing plate 110. A scraping plate 111 is arranged at the bottom of the fixing plate 110. The scraping plate 111 is attached to the inner side wall of the mixing tank 101. A high-pressure spray head 114 is further arranged on the fixing plate 110. A water pump 112 is also installed on the mounting frame 102. The input end of the water pump 112 is connected to an external water source. The output end of the water pump 112 is provided with a corrugated pipe 113. One end of the corrugated pipe 113 far from the water pump 112 is connected to the high-pressure spray head 114. When the mixed raw materials are discharged from the inside of the mixing tank 101 through the discharge valve on the mixing tank 101, start the hydraulic cylinder 103 to drive the mounting plate 104 to rise, so that the stirring blades 119 are separated from the mixing tank 101. Start the electric push rod 109 to drive the fixing plate 110 to descend, so that the scraping plate 111 is attached to the inner side wall of the mixing tank 101. Start the rotating assembly to drive the rotating disk 107 to rotate on the mounting base 106, so that the mixing tank 101 rotates. Thus, the raw materials attached to the inner side wall of the mixing tank 101 are scraped off by the scraping plate 111. And start the water pump 112. Through the cooperation of the corrugated pipe 113 and the high-pressure spray head 114, a high-pressure water column is sprayed onto the inner side wall of the mixing tank 101, so that the cleaning effect is better. With the above structure, through the setting of the cleaning mechanism, when cleaning the inner wall of the mixing tank 101, the cleaning efficiency is higher.

[0025] Secondly, a driven tooth part 120 is arranged on one side of the rotating disk 107 located inside the mounting base 106.

The output gear 117 is arranged at one end of the output shaft 116 far from the servo motor 115. The output gear 117 meshes with the driven tooth part 120. Start the servo motor 115 to drive the output gear 117 to rotate through the output shaft 116. Since the output gear 117 meshes with the driven tooth part 120, the rotating disk 107 is driven to rotate on the upper surface of the mounting base 106.

[0026] Meanwhile, a wiring hole 121 is provided on the side wall of the mounting base 106. The wiring hole 121 corresponds to the servo motor 115. Through the arrangement of the wiring hole 121, the wiring of the servo motor 115 is completed. Since the number of teeth of the output gear 117 is less than the number of teeth of the driven tooth portion 120, when the rotating disk 107 rotates on the upper surface of the mounting base 106, the rotation speed is more controllable.

[0027] In addition, a heat dissipation groove 122 is provided through the outer side wall of the mounting base 106. The heat dissipation groove 122 corresponds to the servo motor 115. Through the arrangement of the heat dissipation groove 122, the interior of the mounting base 106 is kept in communication with the outside air, so that the heat generated by the servo motor 115 during operation is carried away by the flowing air.

[0028] When using the mixing device for petroleum drilling additives of this embodiment, after adding various raw materials for the production of petroleum drilling additives into the mixing tank 101, start the hydraulic cylinder 103 to drive the mounting plate 104 to descend, so that the stirring blades 119 are located inside the mixing tank 101. Start the drive motor 105, and drive the stirring blades 119 to rotate through the stirring shaft 118, thereby using the stirring blades 119 to complete the mixing of various raw materials. And when the mixed raw materials are discharged from the inside of the mixing tank 101 through the discharge valve on the mixing tank 101, start the hydraulic cylinder 103 to drive the mounting plate 104 to rise, so that the stirring blades 119 are separated from the mixing tank 101. Start the electric push rod 109 to drive the fixing plate 110 to descend, so that the scraping plate 111 is attached to the inner side wall of the mixing tank 101. Start the rotating assembly to drive the rotating disk 107 to rotate on the mounting base 106, so that the mixing tank 101 rotates, thereby scraping off the raw materials attached to the inner side wall of the mixing tank 101 through the scraping plate 111. And start the water pump 112, and through the cooperation of the corrugated pipe 113 and the high-pressure nozzle 114, spray a high-pressure water column onto the inner side wall of the mixing tank 101, so that the cleaning effect is better. With the above structure, through the arrangement of the cleaning mechanism, when cleaning the inner wall of the mixing tank 101, the cleaning efficiency is higher.
