Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mud filtering, in particular to a graded filtering device of a multi-stage pulping machine. Background Art
[0002] With the development of engineering construction technology, mud plays an important role in drilling work. The mud used for drilling can clean the rock cuttings carried by the bottom of the well. The mud also has the function of balancing the side pressure of the well wall rock and forming a mud cake on the well wall to keep the well wall stable and prevent the well wall from collapsing. In the production of mud, sticky mud, also known as clay, is prepared. In the existing technology, a mud machine is used to directly stir and flush the clay to make mud.
[0003] Existing mud machines mostly use a stirrer to stir the mud directly during the pulping process, and output the mud after stirring for a certain period of time. However, it is found in the pulping process that due to the different dissolution rates of the mud, some undissolved mud will remain after pulping. This part of the mud needs further stirring. If it enters the next stage directly, it will affect the product quality. If the stirring time of the pulping machine is extended, the production rate will be slow. The present technical solution is now proposed to make improvements. Utility Model Content

[0016] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.
[0017] See also Figures 1 to 3 The embodiment of the utility model discloses a multi-stage mud pulping machine, which mainly includes a base 1 and an equipment bin 2. The base 1 serves as the basic support of the entire machine to ensure the stable operation of the machine. The equipment bin 2 is installed on the upper part of the base 1, and a working area specifically designed for mud preparation is provided inside.
[0018] The upper part of the working chamber is provided with a receiving port 101 for receiving the sludge material to be processed delivered by the conveying device. The lower part of the working chamber is provided with at least two mud tanks, namely the first mud tank 201 and the second mud tank 202, to achieve multi-stage stirring and dissolution. The first mud tank 201 is located directly below the receiving port 101, and a water supply pipe 3 is provided on its inner wall to facilitate the addition of an appropriate amount of water during the stirring process to adjust the concentration and fluidity of the mud. The axis position of the first mud tank 201 is higher than that of the second mud tank 202, which helps the mud to flow freely under the action of gravity. Then it flows into the next mud tank, and during the production process, the upper part of the first mud tank 201 is basically the prepared mud that dissolves faster. During the stirring process, the sticky mud that takes a long time to dissolve will gather in the lower part of the first mud tank 201 and continue to be stirred. The discharge port of the first mud tank 201 is connected with the feed port of the second mud tank 202, ensuring that the mud that is basically dissolved in the upper part of the first mud tank 201 can smoothly flow from one level to the next level for further stirring and dissolution, making the integrated processing process more continuous and smooth, and preventing shutdowns from affecting production.
[0019] The stirring device includes a stirring shaft arranged horizontally inside the first mud tank 201 and the second mud tank 202, and a plurality of stirring teeth are evenly distributed on the side of the stirring shaft. The stirring teeth rotate under the drive of the driving motor to efficiently stir and mix the mud. In order to improve the stirring effect, the stirring teeth are spirally arranged along the length direction of the stirring shaft, and two rows of stirring teeth are provided on each stirring shaft. In order to ensure that the sludge can be fully dissolved during the production process, the length of the first mud tank 201 is designed to be greater than the length of the material receiving port 101, and the material receiving port 101 is located at Above the starting end of the stirring shaft of the first mud tank 201, after the sludge enters the first mud tank 201, it will gradually move forward with the rotation of the stirring shaft until it reaches the other end away from the material receiving port 101. At this time, the mud has achieved a high solubility through sufficient stirring. Subsequently, the mud enters the second mud tank 202 through the overflow port 401 for further refined stirring. Such a structure can enhance the stirring intensity, while improving the fluidity of the mud and reducing the processing time. The setting of the stirring teeth can ensure sufficient force on the sludge and speed up the slurrying process.
[0020] A baffle 4 is provided between the first mud tank 201 and the second mud tank 202. An overflow port 401 is provided at one end of the baffle 4 for controlling the flow of mud from the first mud tank 201 to the second mud tank 202. When the mud in the first mud tank 201 reaches a certain liquid level, the mud will flow into the second mud tank 202 through the overflow port 401 for the next stage of stirring and dissolving. A filtering device is provided on one side of the overflow port. The filtering device includes a self-cleaning filter screen 402. The filter screen 402 is circular and is rotatably provided on one side of the overflow port 401. A cleaning motor 403 is provided on the side of the filter screen 402. The output end of the cleaning motor 403 is provided with a filter. The rotating shaft has a cleaning brush 404 on the side of the rotating shaft that abuts the filter 402. The bottom of the rotating shaft has a driving gear connected to the circumferential gear arranged on the side of the filter 402. When in use, the mud inside the first mud tank enters the second mud tank through the overflow port 401, and is filtered through the filter 402 when flowing in from the overflow port 401 to ensure the quality of the mud entering the second mud tank 202. Since the mud will adhere to the filter 402, the cleaning motor 403 drives the filter 402 to rotate when in use. While rotating, the cleaning brush 404 brushes the surface of the filter 402 to prevent the filter at the overflow port 401 from being blocked, thereby improving the use effect.
[0021] The mud moves along the longer direction between the first mud trough 201 and the second mud trough 202 to enhance the stirring effect. In the second mud trough 202, the spiral direction of the stirring teeth is opposite to that of the first mud trough 201. This design helps to further refine the mud particles and improve the uniformity of the mud. The outlet of the second mud trough 202 is set at the end away from the overflow port 401, ensuring that the fully stirred mud can be discharged smoothly for subsequent use, which not only improves the dissolution efficiency of the sticky mud and the production rate of the mud, but also ensures the uniformity and stability of the mud, providing high-quality mud material.
