Description

Technical Field

[0001] This utility model relates to the field of drilling construction technology, specifically to a mud preparation device for the drilling process. Background Technology

[0002] In the laying of underground pipelines, drilling rigs are used to drill holes. A casing is installed on the outside of the drill rod, and this casing is installed inside the pipeline during drilling. During operation, drilling mud is introduced to cool the drill bit. Most existing mud preparation equipment has a simple structure, typically involving adding mud and water to a mixing tank in a specific ratio, then mixing the mud and water using a handheld mixer to create mud. This traditional method requires operators to work at a higher intensity, constantly moving the handheld mixer within the tank. Furthermore, if the mud is not used promptly after preparation, sediment easily settles at the bottom of the tank. When needed, the mud must be re-mixed using a handheld mixer, but this handheld mixer cannot easily reach the bottom of the tank, making it impossible to scrape off the sediment. This can lead to incorrect mud-to-water ratios, affecting the quality of the final mud. Therefore, we propose a drilling mud preparation device. Utility Model Content

[0003] The purpose of this invention is to provide a drilling mud preparation device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a drilling mud preparation device, comprising a base, an equipment housing fixedly connected to the surface of the base, a feed hopper fixedly connected to the top of the equipment housing, a water inlet pipe fixedly connected to the top of the equipment housing, a discharge pipe fixedly connected to the side wall of the equipment housing, a switch valve fixedly installed in the water inlet pipe and the discharge pipe respectively, and a stirring mechanism fixedly installed in the middle of the equipment housing;

[0005] The stirring mechanism includes a drive motor, which is fixedly mounted at the top center of the equipment housing. The output end of the drive motor is fixedly connected to a drive shaft that extends into the equipment housing. A stirring frame is fixedly mounted on the side wall of the drive shaft. A lifting assembly is fixedly mounted between the drive shaft and the base.

[0006] Preferably, the drive shaft includes a fixed shaft, a telescopic cavity is provided inside the fixed shaft, a telescopic shaft is slidably connected inside the telescopic cavity, a lifting shaft is fixedly connected to the bottom of the telescopic shaft, and a support spring is fixedly assembled between the telescopic shaft and the telescopic cavity.

[0007] Preferably, the telescopic shaft is cross-shaped.

[0008] Preferably, the lifting assembly includes a support base, which is fixedly mounted at the center of the base. The top of the support base is integrally formed with a directional track, and the bottom of the drive shaft is fixedly connected to a mounting block, with guide wheels fixedly mounted on the bottom of the mounting block.

[0009] Preferably, a protective cover is fixedly fitted onto the surface of the base.

[0010] Preferably, the stirring frame includes a fixing block, which is fixedly connected to the side wall of the drive shaft. A bottom frame and a top frame are fixedly connected to the bottom and top of the fixing block, respectively, and a stirring rod is fixedly assembled inside the top frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are: a drilling mud preparation device that adds mud and water to the equipment shell in a certain proportion, and mixes the mud and water to form mud through a stirring mechanism. Compared with the traditional hand-held stirring device for mud preparation, this utility model can effectively reduce the labor intensity of operators. The stirring mechanism fully mixes the mud and water. At the same time, the stirring mechanism is also equipped with a lifting component that works in conjunction with it. The lifting component allows the stirring frame of the stirring mechanism to reciprocate up and down along the center of the equipment shell during the stirring process. This not only enhances the mixing effect of mud and water, but also scrapes away the mud at the bottom of the equipment shell by the movement of the stirring frame at the bottom of the equipment shell, preventing the mud from accumulating at the bottom of the equipment shell.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution: a drilling mud preparation device, including a base 1, an equipment housing 2 welded and fixed to the top of the base 1, a feed hopper 3 fixedly mounted on the top of the equipment housing 2, the feed hopper 3 being connected to the inner cavity of the equipment housing 2, through which mud and sand required for mud preparation can be added into the equipment housing 2, a water inlet pipe 4 fixedly mounted on the top of the equipment housing 2, the water inlet pipe 4 being used to add water required for mixing with mud and sand during mud preparation into the equipment housing 2, a discharge pipe 5 fixedly connected to the side wall of the equipment housing 2, the discharge pipe 5 being used to discharge the prepared mud outwards, and a switch valve 6 fixedly mounted in the water inlet pipe 4 and the discharge pipe 5 respectively, the opening and closing of the water inlet pipe 4 and the discharge pipe 5 being controlled by the switch valve 6.

[0020] A stirring mechanism 7 is fixedly installed in the middle of the inner cavity of the equipment housing 2. The stirring mechanism 7 can mix the mud and water put into the equipment housing 2 to form a slurry. The stirring mechanism 7 includes a drive motor 71, which is fixedly installed at the top center of the equipment housing 2. The output end of the drive motor 71 is fixedly connected to a drive shaft 72 that passes through the inner cavity of the equipment housing 2 through a coupling. A stirring frame 8 is welded and fixed to the outer wall of the drive shaft 72, which is evenly distributed in a circle around the drive shaft 72. A lifting component 9 is installed between the bottom of the drive shaft 72 and the center of the base 1. The lifting component 9 can drive the stirring frame 8 to reciprocate up and down during the process of mixing mud and water to form a slurry, thereby enhancing the mixing effect of the stirring frame 8 on mud and water.

[0021] like Figure 3 and Figure 4As shown, the drive shaft 72 includes a fixed shaft 721. A telescopic cavity 722 is formed at the bottom of the fixed shaft 721. A telescopic shaft 723 is slidably connected within the telescopic cavity 722. A lifting shaft 724 is welded and fixed to the bottom of the telescopic shaft 723. The telescopic shaft 723 is cross-shaped. This cross-shaped design allows the fixed shaft 721 to provide power to the telescopic shaft 723, enabling the telescopic shaft 723 to rotate with the fixed shaft 721. Support springs 72, symmetrically distributed vertically, are fixedly mounted between the telescopic shaft 723 and the telescopic cavity 722. 5. The support spring 725 allows the telescopic shaft 723 to be positioned in the middle of the telescopic cavity 722. The lifting assembly 9 drives the lifting shaft 724, enabling it to reciprocate up and down during rotation. The support spring 725 effectively helps the lifting shaft 724 to return to its original position during the up and down stroke. The gap between the telescopic shaft 723 and the bottom of the telescopic cavity 722 is small, preventing mud and sand from entering the telescopic cavity 722 through the gap and affecting the stroke of the telescopic shaft 723.

[0022] like Figure 3 and Figure 4 As shown, the lifting assembly 9 includes a support base 91, which is hollow. The top of the support base 91 is an integrally formed "wave-shaped" undulating directional track 92. The bottom of the lifting shaft 724 is welded and fixed with an installation block 93. The bottom of the installation block 93 is fixedly equipped with guide wheels 94 that are evenly arranged. The guide wheels 94 and the directional track 92 are configured to cooperate with each other. As the installation block 93 rotates, the guide wheels 94 can move along the directional track 92, causing the installation block 93 to drive the lifting shaft 724 to perform reciprocating motion during the lifting process.

[0023] like Figure 2 As shown, a protective cover 10 is fixedly mounted at the center of the base 1. The protective cover 10 protects the lifting assembly 9. The lifting shaft 724 passes through the protective cover 10. A sealing ring (not shown in the figure) is provided at the connection between the lifting shaft 724 and the protective cover 10. The sealing ring improves the sealing between the lifting shaft 724 and the protective cover 10 without affecting the operation of the lifting shaft 724, and prevents mud and sand from entering the protective cover 10 and causing damage to the lifting assembly 9.

[0024] like Figure 5As shown, the mixing frame 8 includes a fixing block 81, which is welded and fixed to the side wall of the lifting shaft 724. A bottom frame 82 is welded and fixed to the bottom of the fixing block 81. The bottom of the bottom frame 82 is in contact with the surface of the base 1. When the fixing block 81 moves the bottom frame 82, it can scrape the mud and sand on the surface of the base 1, preventing the mud and sand from settling and accumulating on the surface of the base 1 during the mud preparation process. At the same time, a top frame 83 is welded and fixed to the top of the fixing block 81. A stirring rod 84 is welded and fixed between the top frame 83 and the fixing block 81. By moving the top frame 83 and the stirring rod 84 in the inner cavity of the equipment housing 2 driven by the fixing block 81, the mud and sand can be fully mixed and stirred, improving the uniformity of the mud and sand mixed with water.

[0025] Working Principle: This utility model is mainly used for preparing mud slurry to be injected into the drilling rig during the use of drilling equipment. Mud and water are added to the equipment housing 2 according to the required proportions. The mud enters from the feed hopper 3, and the water enters from the water inlet pipe 4. Then, the stirring mechanism 7 is activated, causing the drive motor 71 to drive the drive shaft 72, thereby causing the stirring frame 8 to rotate within the inner cavity of the equipment housing 2. This thoroughly mixes the mud and water to form mud slurry. Compared with traditional simple mud preparation methods, this utility model allows the drive shaft 72 to drive the stirring frame 8 to reciprocate up and down strokes via the bottom lifting component 9 during rotation. The rotation of the stirring frame 8 not only prevents the mud from settling at the bottom of the slurry but also enhances the mixing effect of the mud and water, improving the quality of the prepared mud slurry.
