Description

Technical Field

[0001] The utility model relates to the technical field of screening equipment, in particular to a screening equipment for bauxite. Background Art

[0002] Bauxite screening equipment refers to bauxite screening equipment which is mainly used for screening and separation of bauxite during the mining and processing of bauxite. Bauxite is a mineral containing aluminum and is mainly used for refining aluminum. In the process of mining and processing bauxite, special screening equipment is needed for screening and separation to obtain high-quality bauxite.

[0003] After searching, the patent number "CN220716607U" mentioned in the text that "the utility model relates to the field of bauxite powder screening equipment, specifically to a multiple powder selection device, including a screening mechanism for distinguishing and classifying bauxite powder, a vibration mechanism for driving the bauxite screening process, and also includes a dredging mechanism for preventing blockage when screening bauxite; beneficial effects: by providing a driving motor, a sliding rod, a moving block, a dredging roller and a threaded rod, the driving motor drives the threaded rod to rotate, and then drives the moving block to move along the direction of the thread, and the other moving block is slidably connected to the sliding rod, and at the same time drives the dredging roller to move along the lower side of the first screening plate and the second screening plate, the dredging roller is rotatably connected to the moving block, and the dredging roller is provided with a The top rod is matched with the sieve hole, so that when the bauxite is vibrated and screened, the dredging roller cleans the sieve holes of the first and second screening plates by driving the motor forward and reverse rotation to prevent blockage and affect the screening quality and efficiency. "When it is in use, the threaded rod is driven to rotate by the motor forward and reverse rotation, thereby driving the dredging roller to make a reciprocating motion to clean the sieve holes of the screening plate to prevent blockage. However, in the screening process of bauxite, due to the use of vibration screening, the noise is relatively large, the opening is large, and a large amount of dust is generated during the screening process, which is not environmentally friendly and will also endanger the health of workers. In addition, due to the relatively fixed structure, the screening capacity for different sizes is poor, and it is extremely inconvenient when the screening size needs to be changed. At the same time, there is a problem of high feeding position and inconvenience in feeding.

[0004] To this end, we provide a screening device for bauxite to solve the above problems. Utility Model Content

[0005] The present application provides a screening device for bauxite, which solves the problems of high noise during screening, inconvenience in changing the screening size and difficulty in loading.

[0006] The present application provides a screening device for bauxite, comprising a base motor and a multi-stage screening mechanism, wherein the multi-stage screening mechanism is arranged on the upper side of the base motor;

[0007] Preferably, the multi-stage screening mechanism includes an R2 hole screener arranged on the upper side of the base motor, an R4 hole screener is installed on the upper side of the R2 hole screener, an R6 hole screener is installed on the upper side of the R4 hole screener, an R8 hole screener assembly is installed on the upper side of the R6 hole screener, and an upper cover assembly is installed on the upper side of the R8 hole screener assembly.

[0008] Preferably, the R8 hole filter assembly includes a filter frame arranged on the upper side of the R6 hole filter, a discharge port is arranged on the outer side of the filter frame, a limiter is welded on the outer side of the bottom of the filter frame, and the limiters are symmetrically arranged in four groups about the central axis of the discharge port, a filter hole is opened at the bottom of the filter frame, a rotating shaft is installed on the inner side of the center of the filter frame, and a scraper is installed on the upper side of the bottom of the filter frame.

[0009] Preferably, the scraper is connected to the rotating shaft by a slot, and the size of the scraper is the same as that of the screening frame.

[0010] Preferably, a discharge port is welded on the outer side of the screening frame, and the internal gap size of the discharge port is the same as the size of the screening hole.

[0011] Preferably, the upper cover assembly includes an upper cover arranged on the upper side of the rotating shaft, a dust suction port is opened at the center of the upper cover, a fan is installed on the inner side of the dust suction port, a dust suction pipe is installed on the upper side of the dust suction port, and a feeding port is opened on the left side of the dust suction port.

[0012] Preferably, a spiral feeding assembly is installed on the upper side of the feeding port, and the spiral feeding assembly includes a feeding pipe installed on the upper side of the feeding port, a feeding motor is installed on the upper side of the feeding pipe, a spiral feeder is installed on the inner side of the feeding pipe, and a hopper is installed on the outer side of the feeding pipe.

[0013] Preferably, a base is installed on the outer side of the base motor, and limiting rods are welded on the outer side of the base. The limiting rods are distributed in four groups at equal angles around the outer side of the base.

[0014] It can be seen from the above technical scheme that the present application provides a screening device for bauxite. When in use, first, the limiter of the screener with different screening precision is put on the limit rod, and the bauxite to be screened is put into the hopper. The feeding motor rotates to drive the spiral feeder to transport the bauxite from the hopper through the feeding pipe to the feeding port. The bauxite enters the multi-stage screening mechanism, and the motor rotates to drive the scraper to push the bauxite in the screener so that the bauxite of suitable size enters the next layer of screener, and the screened bauxite is pushed to the edge of the screening frame through the inclination angle of the scraper and enters the discharge port. The motor rotates to drive the rotating shaft to rotate, and drives the fan sleeved on the outside of the rotating shaft to rotate, so that the generated dust is sucked into the dust suction pipe for discharge.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. Through the setting of the upper cover assembly, when it is needed, as the motor rotates, the shaft is driven to rotate, thereby driving the fan sleeved on the outside of the shaft to rotate, sucking a large amount of dust generated during the screening process into the dust suction pipe and can be used as a screening category for discharge, which not only improves the environmental cleanliness of the working environment, but also reduces the health threat of dust to operators. When loading is required, the operator only needs to put the bauxite into the hopper, and the loading motor drives the spiral feeder to rotate, which can easily realize the delivery of bauxite to the loading port at a high place;

[0017] 2. Through the setting of multi-stage screening mechanism and the use of rotary screening, the noise during screening can be reduced. During screening, only the required screeners with different screening hole diameters and different numbers need to be inserted into the limit rod and installed on the base to carry out screening work. Rapid conversion of multiple levels and multiple precisions can be achieved, and the difficulty of maintenance and unblocking of screening holes is also reduced. A scraper is installed in the screener. As the scraper rotates, the bauxite can be pushed to allow bauxite of suitable size to enter the next level screener. The bauxite can also be pushed into the discharge port by the inclination angle of the scraper blade. At the same time, the screening holes can be unblocked to avoid affecting the screening efficiency. The discharge port and the screening hole are kept in the same size, which can also ensure that bauxite larger than the desired screening size is not sent into the discharge port during the screening process, thereby improving the screening quality.

[0018] In summary, the present application can quickly replace the screening components according to the required bauxite grade, reducing the trouble of disassembling and assembling a large range of equipment parts due to the inconvenience of replacing the screen due to the relatively fixed structure.

DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0026] See also Figure 1-4 , a screening device for bauxite, comprising a base motor 1 and a multi-stage screening mechanism 2, wherein the multi-stage screening mechanism 2 is arranged on the upper side of the base motor 1;

[0027] The multi-stage screening mechanism 2 includes an R2 hole screener 21 arranged on the upper side of the base motor 1, an R4 hole screener 22 is installed on the upper side of the R2 hole screener 21, an R6 hole screener 23 is installed on the upper side of the R4 hole screener 22, an R8 hole screener assembly 24 is installed on the upper side of the R6 hole screener 23, and an upper cover assembly 25 is installed on the upper side of the R8 hole screener assembly 24.

[0028] In the utility model, the R8 hole filter assembly 24 includes a filter frame 241 arranged on the upper side of the R6 hole filter 23, a discharge port 242 is arranged on the outer side of the filter frame 241, a limiter 243 is welded on the outer side of the bottom of the filter frame 241, and the limiters 243 are symmetrically arranged in four groups about the discharge port 242 on the central axis. A filter hole 244 is opened at the bottom of the filter frame 241, a rotating shaft 245 is installed on the inner side of the center of the filter frame 241, and a scraper 246 is installed on the upper side of the bottom of the filter frame 241. The details can be adjusted according to the actual size to be screened. According to different size requirements, filters with filter holes 244 of different apertures are selected.

[0029] In the utility model, the scraper 246 is connected to the rotating shaft 245 by a slot, and the size of the scraper 246 is the same as that of the screening frame 241. During the screening process, as the scraper 246 rotates, the bauxite can be pushed to move so that bauxite of suitable size can enter the next-level screener. The bauxite can also be pushed into the discharge port 242 by the inclination angle of the scraper 246 blade, and the screening hole 244 can also be unblocked to avoid affecting the screening efficiency.

[0030] In the utility model, a discharge port 242 is welded on the outer side of the screening frame 241, and the internal gap size of the discharge port 242 is the same as the size of the screening hole 244, so that during the screening process, bauxite larger than the desired screening size can be avoided from being fed into the discharge port 242, thereby improving the screening quality.

[0031] In the utility model, the upper cover assembly 25 includes an upper cover 251 arranged on the upper side of the rotating shaft 245, a dust suction port 252 is opened at the center of the upper cover 251, a fan 253 is installed on the inner side of the dust suction port 252, a dust suction pipe 254 is installed on the upper side of the dust suction port 252, and a feeding port 255 is opened on the left side of the dust suction port 252. Except for the different screening hole diameters, the other parts of the R2 hole screener 21, the R4 hole screener 22 and the R6 hole screener 23 are the same as the parts in the R8 hole screener assembly 24. When a large amount of bauxite material enters the feeding port 255 and begins to be screened step by step, due to the rotation of the scraper 246 and the movement of the bauxite, a large amount of dust will inevitably be generated. When the base motor 1 rotates, it will drive the fan 253 to rotate and suck the dust into the dust suction pipe 254, which not only improves the cleanliness of the working environment, but also reduces the health threat of dust to the operating workers.

When feeding is needed, the operator only needs to put bauxite into the hopper 34, and the feeding motor 32 drives the spiral feeder 33 to rotate, so that the bauxite can be easily delivered to the feeding port 255 at a high place.

[0033] In some embodiments, a base 4 is installed on the outside of the base motor 1, and a limiting rod 5 is welded on the outside of the base 4. The limiting rod 5 is distributed in four groups at equal angles around the outside of the base 4. When different screening accuracies or different screening levels are required, the required filter assembly only needs to be inserted into the limiting rod 5 and installed on the base 4 to perform screening work. Rapid replacement of multiple levels and multiple accuracies can be achieved, and the difficulty of maintenance and unblocking of the screening hole 244 is also reduced.

[0034] It can be seen from the above technical scheme that when in use, first, the limiter 243 of the filter with different screening accuracy is put on the limit rod 5, and the bauxite to be screened is put into the hopper 34. The feeding motor 32 rotates to drive the spiral feeder 33 to transport the bauxite from the hopper 34 to the feeding port 255 through the feeding pipe 31, and the bauxite enters the multi-stage screening mechanism 2. The base motor 1 rotates to drive the scraper 246 to push the bauxite in the screener so that the bauxite of suitable size enters the next layer of the screener, and the screened bauxite is pushed to the edge of the screening frame 241 through the inclination angle of the scraper 246, and enters the discharge port 242. The motor rotates to drive the rotating shaft 245 to rotate, and drives the fan 253 sleeved on the outside of the rotating shaft 245 to rotate, so that the generated dust is sucked into the dust suction pipe 254 for discharge. In this way, the use process of a screening device for bauxite is completed.
