Description

Technical Field

[0001] This utility model relates to the field of bentonite drying technology, and in particular to a rotary device for drying bentonite. Background Technology

[0002] Dried bentonite has a lower moisture content and more stable physical and chemical properties, making it better suited for various applications. For example, in drilling mud, casting, and coatings, dried bentonite exhibits better suspension, binding, and adsorption properties.

[0003] Dried bentonite has a low moisture content, reduced volume, and lighter weight, making it easier to store and transport. This reduces transportation costs and storage space requirements, while also lowering the risk of spoilage due to moisture. Furthermore, drying reduces dust and pollution generated during bentonite use, which is beneficial for environmental protection. For example, using dried bentonite in drilling mud can reduce the water content of the mud and lower the difficulty of wastewater treatment. For instance, Chinese Patent Publication No. CN216308474U provides a rotary device for drying bentonite. This rotary device includes: a base plate and support frames symmetrically arranged on the upper surface of the base plate; two wheels rotatably connected to each support frame; a cylinder rotatably connected between the two wheels; a stirring component including a support rod, a stirring rod, and a sleeve; one end of the support rod being fixedly connected to the inner wall of the cylinder; vertical rods arranged in an equidistant array on the support rod; the sleeve being installed at the lower end of the vertical rods; the stirring rod being fixedly connected to the bottom end of the sleeve; and a limiting component including a ring fixedly connected to the inner wall of the cylinder. In this invention, when the sleeve rotates, the stirring rod fixed to the sleeve can stir the bentonite inside the cylinder, breaking up clumps of bentonite and achieving a better drying effect.

[0004] Currently, some bentonite drying is carried out in drying rooms. However, the drying room can only spread the bentonite out. If the pile is thick, it needs to be turned over manually from time to time. Although the drying volume is large, the drying efficiency and uniformity are greatly reduced. In addition, the exhaust gas, dust and high heat during the drying process can cause varying degrees of harm to the human body when people enter the drying room. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a rotary device for drying bentonite.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a rotary device for drying bentonite, including a base, a cylinder is arranged on the top of the base, the lower end of the outer wall of the cylinder is fixed to the surface of the base by a bracket, the cylinder is tilted, one end of the cylinder is a closed end and the other end is an open end, a bearing is arranged through the center of the closed end of the cylinder, the bearing is fixed to the cylinder by welding, a shaft is arranged through the inside of the bearing, and the surface of the shaft is interference fit with the inner ring wall of the bearing;

[0008] The shaft has several connecting rods distributed at one end inside the cylinder. One end of each connecting rod is fixed to the surface of the shaft with screws. The ends of the multiple connecting rods arranged in the same row are connected and fixed to the same flipping plate. The flipping plate has an arc-shaped structure and slides in contact with the inner wall of the cylinder. A motor is installed at the outer end of the shaft. The outer wall of the motor is fixedly assembled to the surface of the cylinder through a bracket. The motor has a drive shaft inside. The end of the drive shaft is fixedly connected to the end of the shaft through a coupling.

[0009] The closed end of the cylinder is also provided with a feed port, and the feed port is fixed to the cylinder by welding. The open end of the cylinder is covered with a sealing plate.

[0010] In detail, a hot air blower is installed above the cylinder, and the lower end of the hot air blower is fixedly assembled to the surface of the cylinder through a bracket. A duct is connected to the air outlet of the hot air blower via a flange, and the duct is located above the cylinder and is arranged parallel to it.

[0011] In detail, a nozzle is provided through the lower end of the air duct, and the end of the nozzle is embedded in and penetrates the upper end of the outer ring wall of the cylinder.

[0012] In detail, an exhaust port is provided through the top of the cylinder, and the connection between the exhaust port and the cylinder is fixed by welding.

[0013] In detail, the exhaust port has a grille, an activated carbon filter and a frame arranged vertically inside. The inner side of the frame is provided with a non-woven fabric filter. The grille is made of aluminum alloy wire mesh. The edges of the grille, the activated carbon filter and the frame are fixedly assembled to the inner wall of the exhaust port.

[0014] In detail, a threaded post is provided on the outer wall of the open end of the cylinder. The end of the threaded post is welded and fixed to the surface of the cylinder. An inner sleeve is provided through the surface of the sealing plate. The inner sleeve is welded and fixed to the connection position of the sealing plate. The threaded post and the inner sleeve are interpenetrating. There are at least two threaded posts, which are evenly distributed along the outer wall of the cylinder.

[0015] In detail, the outer end of the threaded column is threadedly connected to a threaded sleeve, the end face of the threaded sleeve is tightly fitted to the end face of the inner sleeve, and a knob is fixed to the end of the threaded sleeve.

[0016] The design scheme proposed in this utility model has the following beneficial effects in application:

[0017] 1. When bentonite needs to be dried, moist bentonite can be fed into the cylinder through the feed interface. Then, the motor is started synchronously, which drives the shaft to rotate. This causes the turning plate at the end of the connecting rod to turn and agitate the continuously fed bentonite. This turning can be done continuously during the drying process to ensure the uniformity and efficiency of drying. When it is time to discharge, the threaded sleeve can be rotated by the knob to separate the threaded sleeve from the threaded column. This allows the inner sleeve to be separated from the threaded column, and the sealing plate can be separated from the cylinder. Workers can then use a shovel to remove the dried bentonite from the cylinder.

[0018] 2. When drying is required, turn on the power of the hot air blower. The hot air blower generates hot airflow, which is transported through the air duct and distributed to each air nozzle. Through the air nozzle, it can be blown into the cylinder to dry the bentonite that is constantly being turned over. When it is necessary to continuously exhaust air to ensure air circulation, auxiliary exhaust can be performed through the exhaust port to avoid excessive air pressure in the cylinder, which would affect the flow of hot airflow. During exhaust, fine dust can be isolated and blocked through the non-woven fabric filter, odor can be adsorbed and filtered through the activated carbon filter, and the activated carbon filter can be protected from the outside through the grille.
