Description

Technical Field

[0001] The utility model relates to the field of barite, and more specifically, to a barite dehydration device. Background Art

[0002] Barite is the most common mineral of barium, and its component is barium sulfate. It is produced in low-temperature hydrothermal veins, such as quartz-barite veins, fluorite-barite veins, etc., and is often symbiotic with galena, sphalerite, chalcopyrite, cinnabar, etc. In the mining and production of barite, it is necessary to dehydrate barite for subsequent processing procedures. Generally, a dehydration screen is usually used to dehydrate barite. The existing dehydration screen generally uses a vibration motor to drive a horizontally arranged screen to perform a linear reciprocating motion. The motion of the screen is used to dehydrate barite while continuously pushing it towards the discharge end to complete the entire dehydration work. However, the efficiency of dehydration and feeding by vibration is relatively low, which will cause the overall progress speed of the barite dehydration process to be relatively slow.

[0004] To make up for the above deficiencies, the utility model provides a barite dehydration device, aiming to improve the problem that barite dehydration is usually completed by a dehydration screen. The existing dehydration screen generally uses a vibration motor to drive a horizontally arranged screen to perform a linear reciprocating motion. The motion of the screen is used to dehydrate barite while continuously pushing it towards the discharge end to complete the entire dehydration work. However, the efficiency of dehydration and feeding by vibration is relatively low, which will cause the overall progress speed of the barite dehydration process to be relatively slow.

An annular sliding block is slidably connected inside the annular groove. The annular sliding block is arranged on the outer wall of the bottom circumferential circle of the dehydration barrel.

[0007] In a preferred technical solution of the present utility model, the reverse driving mechanism includes a mounting plate fixedly installed on the inner wall of one side of the frame.

Specific embodiments

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a barite dehydration device, including a frame 5, the frame 5 is integrally in a C-shaped structure, a mounting bracket 4 is fixedly connected to the inner wall of the bottom of the frame 5, a dehydration bucket 1 is rotatably connected to the mounting bracket 4, a material guiding part 2 is arranged inside the dehydration bucket 1, a reverse driving mechanism 3 is fixedly installed on one inner wall of the frame 5, the material guiding part 2 is rotatably connected to the inner wall of the top of the frame 5 through the reverse driving mechanism 3, the dehydration bucket 1 is also connected to the reverse driving mechanism 3 at the same time, a plurality of annularly and evenly distributed water seepage tanks 101 are annularly arranged on the outer wall of the dehydration bucket 1, and a threaded material guiding plate 201 is arranged on the outer wall of the material guiding part 2.

[0021] Please refer to Figure 4, the mounting bracket 4 includes a mounting ring 401. A plurality of legs 402 are arranged on the circumferential surface of the mounting ring 401 in a uniformly distributed annular manner. One end of each leg 402 is fixedly connected to the inner wall of the bottom of the frame 5. An annular groove 403 is formed on the inner circumferential wall of the mounting ring 401. An annular slider 404 is slidably connected inside the annular groove 403. The annular slider 404 is arranged on the outer circumferential wall of the bottom end of the dewatering barrel 1.

[0022] The dewatering barrel 1 is slidably connected to the annular groove 403 provided on the inner wall of the mounting ring 401 through the annular slider 404 provided on the inner circumferential wall of the bottom end. Moreover, the dewatering barrel 1 is also connected to the reverse driving mechanism 3. Therefore, driven by the reverse driving mechanism 3, the dewatering barrel 1 can rotate independently relative to the frame 5.

[0023] Furthermore, the reverse driving mechanism 3 includes a mounting plate 301. The mounting plate 301 is fixedly installed on the inner wall of one side of the frame 5. A motor 302 is fixedly installed on one surface of the mounting plate 301. One end of the output shaft of the motor 302 is fixedly connected to one end of the first rotating shaft 303. A gear 304 is fixedly sleeved on the first rotating shaft 303. The gear 304 is meshed with a tooth ring 305 on one side. The tooth ring 305 is arranged on the outer circumferential wall of the top end of the dewatering barrel 1.

[0024] When the motor 302 drives the first rotating shaft 303 to rotate, the gear 304 will also rotate synchronously. The gear 304 is meshed with the tooth ring 305 arranged on the outer circumferential surface of the top end of the dewatering barrel 1. Therefore, when the first rotating shaft 303 rotates, the whole dewatering barrel 1 will rotate synchronously.

[0025] Furthermore, a first sprocket 306 is also fixedly sleeved on the first rotating shaft 303. A chain 307 is sleeved on the first sprocket 306. The chain 307 is drivingly connected to a second sprocket 308. The second sprocket 308 is fixedly sleeved on a second rotating shaft 309. One end of the second rotating shaft 309 is rotatably connected to the inner wall of the top of the frame 5. The other end of the second rotating shaft 309 is fixedly connected to the top surface of the material guiding part 2.

[0026] When the motor 302 drives the first rotating shaft 303 to rotate so that the dehydration barrel 1 rotates synchronously, the first sprocket 306 will also rotate synchronously, and the second sprocket 308 is fixedly sleeved on the second rotating shaft 309. The guide part 2 is rotatably connected to the inner wall of the top of the frame 5 through the second rotating shaft 309, and the second sprocket 308 and the first sprocket 306 are connected by the chain 307. Therefore, when the dehydration barrel 1 rotates, the guide part 2 will also rotate synchronously inside the dehydration barrel 1. At the same time, because the dehydration barrel 1 is directly meshed with the gear 304 through the gear ring 305, the rotation direction of the dehydration barrel 1 is the same as the rotation direction of the first rotating shaft 303. The second rotating shaft 309 and the first rotating shaft 303 are driven by the transmission connection of the first sprocket 306, the chain 307 and the second sprocket 308, so the rotation direction of the second rotating shaft 309 and the first rotating shaft 303 must be consistent. Therefore, when the reverse driving mechanism 3 drives the dehydration barrel 1 and the material guiding part 2 to rotate synchronously, the rotation directions of the dehydration barrel 1 and the material guiding part 2 must be opposite. While the material guiding part 2 transports the barite to the bottom end of the dehydration barrel 1, the dehydration barrel 1 exerts a force on the material in the reverse direction, thereby dehydrating the barite by centrifugal force. The dehydration efficiency of the barite can be greatly improved by adopting vertical transportation and utilizing centrifugal force.

[0027] See also Figures 1 to 3 A feed hopper 6 is fixedly connected to the surface of one side of the top of the frame 5 , and one end of the feed hopper 6 extends into the dehydration barrel 1 and is located between the inner wall of the dehydration barrel 1 and the surface of the material guide part 2 .

[0028] Because the dehydration barrel 1 will rotate when in operation, when feeding into the space between the dehydration barrel 1 and the material guide part 2, the barite may be thrown out due to the centrifugal force, which may cause danger. Therefore, a feed hopper 6 is installed on the top of the frame 5. The feed hopper 6 extends a certain distance into the area between the inside of the dehydration barrel 1 and the material guide part 2, thereby avoiding the barite from being thrown out when feeding, thereby improving the convenience and safety of use.

[0029] Furthermore, the dewatering barrel 1 and the material guiding portion 2 are both conical structures that are larger at the top and smaller at the bottom.

[0030] The conical structure can make the barite always keep in contact with the inner wall of the dehydration barrel 1 during the process of being transported downward and dehydrated, thereby improving the dehydration efficiency.

[0031] Furthermore, the distance between the surface of the threaded guide plate 201 facing the inner wall of the dehydration barrel 1 and the inner wall of the dehydration barrel 1 gradually decreases from top to bottom.

[0032] In this way, some smaller barites can slide directly down along the inner wall of the dehydration barrel 1 to the appropriate threaded guide plate 201 layer, thereby accelerating the dehydration of the barite and thus improving work efficiency. In this way, large and small barites can be preliminarily separated to avoid blockage caused by large and small barites being transported together, thereby ensuring stability during use.

[0033] Working principle: add the ore and mud mixture from the feed hopper 6 to the inside of the dewatering barrel 1, start the motor 302 to drive the first shaft 303 to rotate so that the dewatering barrel 1 rotates synchronously, and the first sprocket 306 also rotates synchronously, and the second sprocket 308 is fixedly sleeved on the second shaft 309, and the guide part 2 is rotatably connected to the top inner wall of the frame 5 through the second shaft 309, and the second sprocket 308 and the first sprocket 306 are connected by the chain 307 transmission, so when the dewatering barrel 1 rotates, the guide part 2 will also rotate synchronously inside the dewatering barrel 1, and at the same time, because the dewatering barrel 1 is directly meshed with the gear ring 305 and the gear 304, the rotation direction of the dewatering barrel 1 must be opposite to the rotation direction of the first shaft 303, and the second shaft 309 is connected to the first shaft 303 is transmitted through the transmission connection of the first sprocket 306, the chain 307 and the second sprocket 308, so the rotation directions of the second rotating shaft 309 and the first rotating shaft 303 must be consistent. Therefore, when the reverse driving mechanism 3 drives the dehydration barrel 1 and the material guide part 2 to rotate synchronously, the rotation directions of the dehydration barrel 1 and the material guide part 2 must be opposite. While the material guide part 2 transports the barite to the bottom end of the dehydration barrel 1, the dehydration barrel 1 applies a force to the material in the reverse direction, thereby dehydrating the barite through centrifugal force. The dehydration efficiency of the barite can be greatly improved by adopting vertical transportation and utilizing centrifugal force. The dehydrated barite is discharged from the bottom opening of the dehydration barrel 1. The user can set a transmission device at the bottom opening of the dehydration barrel 1 to collect the barite, and the moisture is thrown out by the seepage trough 101.

[0034] It should be noted that the specific model and specifications of the motor 302 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0035] The power supply and principle of the motor 302 are clear to those skilled in the art and will not be described in detail here.

[0036] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
