Description

Technical Field

[0001] This utility model relates to the field of screening device technology, specifically a rutile titanium ore grading and screening device. Background Technology

[0002] Rutile titanium ore, as a core raw material for the production of key products such as titanium dioxide and sponge titanium, directly determines the processing efficiency, energy consumption, and final performance of downstream products through its quality and particle size classification accuracy. In the industrial processing of rutile titanium ore, classification and screening are crucial links between mining and deep processing. The raw ore or coarsely crushed material needs to be separated into multiple particle size grades according to different application requirements, providing homogenized raw materials for subsequent grinding, purification, and other processes. Therefore, the efficiency, classification accuracy, and automation level of the screening equipment become core factors affecting the capacity and economics of titanium ore processing production lines.

[0003] Currently, the grading and screening equipment commonly used in the rutile titanium ore industry mainly includes fixed grid screens, vibrating screens, and ordinary drum screens. However, existing grading and screening methods mostly adopt the mode of "single-stage screening + manual transfer" or "multiple devices connected in series but operating independently". For example, large-diameter ore is first separated by a coarse screen, and then the undersize fine material is manually transferred to a secondary fine screening device. The entire process requires interrupting the screening process for material transfer, which not only leads to poor production line continuity and high labor time loss, but also easily causes raw material waste or grading gaps due to human operation errors (such as material spillage or untimely transfer), making it inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to provide a rutile titanium ore grading and screening device to solve the problem of inconvenient mineral screening mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rutile titanium ore grading and screening device, comprising a frame, a lower box fixedly installed on the outer surface of the frame, and the lower box being inclined; a fine screen roller rotatably installed on the outer surface of the lower box; a medium screen roller fixedly installed on one end of the outer surface of the fine screen roller; a coarse screen roller fixedly installed on one end of the outer surface of the medium screen roller; the coarse screen roller, medium screen roller, and fine screen roller are fixedly connected by bolts; blade baffles are fixedly installed on the outer surfaces of both ends of the medium screen roller and the coarse screen roller, and through holes are provided between the blade baffles and the coarse and medium screen rollers; the blade baffles are inclined, and the blade baffles are respectively in contact with the outer surfaces of the fine screen roller, medium screen roller, and coarse screen roller.

[0006] Preferably, support wheels are fixedly installed on the outer surfaces of both ends of the frame, and track grooves are fixedly installed on the outer surfaces of the fine sieve roller and the coarse sieve roller, and the track grooves engage with the support wheels, and the outer surfaces of the support wheels are in contact with the outer surfaces of the track grooves. A gear ring is fixedly installed on the outer surface of the fine sieve roller, and the gear ring and the fine sieve roller are concentrically designed. A geared motor is fixedly installed on the outer surface of the frame near the gear ring, and a gear is fixedly installed on the output end of the geared motor, and the gear meshes with the gear ring.

[0007] Using the above technical solution, the support wheels can support and assemble the fine screen cylinder, medium screen cylinder, and coarse screen cylinder. This allows the track groove to rotate along the gear driven by the reduction motor, so that the gear ring meshing with the gear can rotate synchronously, allowing the minerals fed into the fine screen cylinder, medium screen cylinder, and coarse screen cylinder to be screened evenly.

[0008] Preferably, a top cover is fixedly installed on the outer surface of the lower box, and the outer surface of the top cover is respectively in contact with the outer surfaces of the fine sieve roller and the coarse sieve roller, and the outer surfaces of both ends of the middle sieve roller are respectively in contact with the outer surface of the lower box.

[0009] By adopting the above technical solution, the top cover can shield and limit the fine screen roller, medium screen roller, and coarse screen roller, greatly reducing the dust from spreading during screening and reducing the risk of the fine screen roller, medium screen roller, and coarse screen roller derailing and running off the track during rotation.

[0010] Preferably, an inspection and observation port is fixedly installed on one side of the outer surface of the lower housing, and the inspection and observation port is fixed to the lower housing with screws.

[0011] By adopting the above technical solution, the interior of the lower box can be easily inspected and the interior of the hopper can be easily cleaned by removing the inspection and observation port.

[0012] Preferably, a feed inlet is fixedly installed on the outer surface of one end of the frame, and the feed inlet is inserted into one end of the fine screen roller, and the feed inlet is designed in the shape of a bucket. A discharge port is fixedly installed on the end of the frame away from the fine screen roller, and the discharge port is rotatably connected to the blade baffle, and the blade baffle is inserted into the discharge port.

[0013] By adopting the above technical solution, the hopper design of the feed inlet makes it easy to put minerals into the fine screen cylinder, improving the convenience of material input. After the mineral screening is completed, minerals that do not meet the size requirements can enter the discharge port and be discharged outwards. At the same time, the feed inlet and discharge port can further limit the movement of the fine screen cylinder, medium screen cylinder, and coarse screen cylinder.

[0014] Preferably, flushing pipes are fixedly installed on the outer surfaces of both ends of the top cover, and the flushing pipes penetrate the outer surface of the top cover. The flushing pipes are designed as mist nozzles.

[0015] By adopting the above technical solution, the outer surfaces of the fine screen roller, medium screen roller, and coarse screen roller can be flushed by the water sprayed from the flushing pipe, so that the outer surfaces of the fine screen roller, medium screen roller, and coarse screen roller will not be blocked, and the minerals can be flushed, ensuring the passage of the fine screen roller, medium screen roller, and coarse screen roller during screening, reducing the mineral screening time, and improving the quality of mineral screening.

[0016] Preferably, a feeding hopper is fixedly installed on the outer surface of the lower housing, and a screw conveyor motor assembly is fixedly installed on one side surface of the feeding hopper. The output end of the screw conveyor motor assembly is rotatably connected to the feeding hopper, and through holes are uniformly opened on the outer surface of the feeding hopper. A feeding pipe is opened on the outer surface of the feeding hopper near the reduction motor.

[0017] By adopting the above technical solution, the water flowing down from the washing can be discharged through the through holes opened on the outer surface of the hopper, and at the same time, the rotation of the screw conveyor motor assembly can discharge the screened minerals from the feed pipe, so that the minerals can be transported elsewhere.

[0018] Compared with the prior art, the beneficial effects of this utility model are: This rutile titanium ore grading and screening device:

[0019] 1. The rotation of the fine screen drum, medium screen drum, and coarse screen drum can drive the minerals to tumble and rotate, allowing the minerals to be quickly screened inside the fine screen drum, medium screen drum, and coarse screen drum. The reverse rotation can also lift the remaining minerals and send them into the next drum, so that all the minerals can roll and screen at the same time, reducing mineral loss, greatly reducing mineral waste, reducing manpower for handling, and simultaneously screening out minerals of different sizes.

[0020] 2. By closing the lower housing and the top cover, the fine screen roller and the coarse screen roller can be clamped and limited, preventing them from shifting during rotation. Combined with the use of the track groove, the track groove can rotate in the direction of the support wheel, greatly reducing the chance of the fine screen roller, the medium screen roller, and the coarse screen roller derailing and falling off during rotation. Furthermore, the closing and fixing of the lower housing and the top cover prevents dust from scattering and causing environmental pollution during mineral screening, ensuring the limiting of the fine screen roller, the medium screen roller, and the coarse screen roller, and reducing environmental pollution.

[0021] 3. The hopper can collect minerals of different sizes after screening, and through the rotation of the screw conveyor motor assembly, the minerals can be transported along with the rotation of the screw conveyor motor assembly, so that the minerals can be discharged from the discharge pipe, and minerals of different sizes can be collected and discharged.

[0022] 4. After prolonged use, the screen holes of fine, medium, and coarse screen rollers may become clogged, resulting in longer screening times. In this case, the flushing pipe can be activated to flush the surface of the fine, medium, and coarse screen rollers, allowing the blocked minerals to be cleared and greatly improving the screening efficiency and quality of the minerals.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-6 This utility model provides a technical solution: a rutile titanium ore grading and screening device, including a frame 1, a lower box 2 fixedly installed on the outer surface of the frame 1, and the lower box 2 is inclined; a feed inlet 10 is fixedly installed on the outer surface of one end of the frame 1, and the feed inlet 10 is inserted into one end of the fine screen roller 3, and the feed inlet 10 is bucket-shaped; a discharge port 11 is fixedly installed on the end of the frame 1 away from the fine screen roller 3, and the discharge port 11 is rotatably connected to the blade baffle 6, and the blade baffle 6 is inserted into the discharge port 11.

[0032] Firstly, when using it, simply put the mineral into the fine screen cylinder 3 through the feed inlet 10. Then, the rotation of the geared motor 12 will cause the fine screen cylinder 3, the medium screen cylinder 4, and the coarse screen cylinder 5 to rotate to screen the mineral. After the mineral screening is completed, the reverse blade baffle 6 will scoop up the minerals that do not meet the size requirements and discharge them from the discharge port 11.

[0033] Support wheels 8 are fixedly installed on the outer surfaces of both ends of the frame 1. Track grooves 7 are fixedly installed on the outer surfaces of the fine screen roller 3 and the coarse screen roller 5, and the track grooves 7 are engaged with the support wheels 8. The outer surfaces of the support wheels 8 are in contact with the outer surfaces of the track grooves 7. A gear ring 13 is fixedly installed on the outer surface of the fine screen roller 3, and the gear ring 13 and the fine screen roller 3 are concentrically designed. A geared motor 12 is fixedly installed on the outer surface of the frame 1 near the gear ring 13, and a gear 14 is fixedly installed on the output end of the geared motor 12, and the gear 14 meshes with the gear ring 13.

[0034] Secondly, the support wheel 8 supports the assembled fine screen roller 3, medium screen roller 4, and coarse screen roller 5. When the gear motor 12 drives the gear 14 to rotate, the gear 14 drives the gear ring 13 to rotate, allowing the gear ring 13 to drive the fine screen roller 3, medium screen roller 4, and coarse screen roller 5 to rotate together. The engagement of the track groove 7 with the support wheel 8 prevents the fine screen roller 3, medium screen roller 4, and coarse screen roller 5 from shifting during rotation, greatly improving the stability of the screening device during operation.

[0035] A fine sieve roller 3 is rotatably mounted on the outer surface of the lower housing 2. A top cover 9 is fixedly mounted on the outer surface of the lower housing 2, and the outer surface of the top cover 9 is in contact with the outer surfaces of the fine sieve roller 3 and the coarse sieve roller 5, respectively. A rinsing pipe 16 is fixedly mounted on the outer surface of both ends of the top cover 9, and the rinsing pipe 16 penetrates the outer surface of the top cover 9. The rinsing pipe 16 is designed as a mist nozzle. The outer surfaces of both ends of the medium sieve roller 4 are in contact with the outer surface of the lower housing 2, and a medium sieve roller 4 is fixedly mounted on the outer surface of one end of the fine sieve roller 3. A coarse screen roller 5 is fixedly installed on the outer surface of one end of the medium screen roller 4, and the coarse screen roller 5, the medium screen roller 4, and the fine screen roller 3 are fixedly connected by bolts. Blade baffles 6 are fixedly installed on the outer surfaces of both ends of the medium screen roller 4 and the coarse screen roller 5, and through holes are provided between the blade baffles 6 and the coarse screen roller 5 and the medium screen roller 4. The blade baffles 6 are inclined and fit against the outer surfaces of the fine screen roller 3, the medium screen roller 4, and the coarse screen roller 5, respectively.

[0036] Furthermore, as the fine-mesh roller 3, medium-mesh roller 4, and coarse-mesh roller 5 rotate, the minerals fed into the screening device tumble and rotate, allowing them to fall through the sieve holes on the surface of these rollers. After the fine-mesh roller 3, medium-mesh roller 4, and coarse-mesh roller 5 have rotated for a certain period, the reduction motor 12 can be started in reverse, allowing the fine-mesh roller 3, medium-mesh roller 4, and coarse-mesh roller 5 to rotate in the opposite direction. Combined with the inclined design of the lower housing 2 and the frame 1, the blade baffle 6 can also rotate in the opposite direction, allowing the screened minerals to be lifted by the blade baffle 6 and pass through the through holes into the next roller. The minerals are continuously screened by the re-rotation of the fine screen roller 3, medium screen roller 4, and coarse screen roller 5. At the same time, the flushing pipe 16 can clean the blockages in the fine screen roller 3, medium screen roller 4, and coarse screen roller 5. The top cover 9 can block dust during screening and block water during flushing, maintaining the filtration efficiency and quality of the fine screen roller 3, medium screen roller 4, and coarse screen roller 5. This allows for continuous screening of minerals and enables continuous and efficient rolling screening of minerals of different specifications through the rotation of the fine screen roller 3, medium screen roller 4, and coarse screen roller 5, greatly improving the convenience of screening.

[0037] Inspection and observation ports 15 are fixedly installed on one side of the outer surface of the lower housing 2, and the inspection and observation ports 15 are fixed to the lower housing 2 with screws. A feeding hopper 17 is fixedly installed on the outer surface of the lower housing 2, and a screw conveyor motor assembly 18 is fixedly installed on one side surface of the feeding hopper 17. The output end of the screw conveyor motor assembly 18 is rotatably connected to the feeding hopper 17, and through holes are evenly opened on the outer surface of the feeding hopper 17. A feeding pipe 19 is opened on the outer surface of the feeding hopper 17 near the reduction motor 12.

[0038] Furthermore, the inspection and observation port 15 can be removed for inspection and maintenance, allowing the hopper 17 to receive and store minerals of different sizes after screening. Then, the rotation of the screw conveyor motor assembly 18 allows the minerals stored in the lower box 2 to be discharged from the discharge pipe 19, facilitating the discharge of minerals of different sizes and reducing the probability of minerals remaining in the hopper 17.

[0039] Working principle: When screening minerals, the minerals can be fed into the screening device through the feed inlet 10. Then, the forward rotation of the reduction motor 12 drives the gear 14 to rotate, causing the gear ring 13 meshing with the gear 14 to rotate as well. This allows the fine screen cylinder 3 to rotate and screen the minerals first. After rotating for a period of time, the reduction motor 12 is started in reverse, causing the blade baffle 6 to rotate in the reverse direction and lift the minerals and feed them into the medium screen cylinder 4. A certain amount of minerals is then fed back into the fine screen cylinder 3, and the forward rotation is used for screening again. After that, the rotation is reversed so that the minerals re-enter the coarse screen cylinder 5, allowing the minerals to rotate continuously and be screened continuously. By using the fine screen cylinder 3, medium screen cylinder 4, and coarse screen cylinder 5, minerals of different sizes can be screened continuously and sequentially. This gradual screening reduces complicated transportation steps and the loss of minerals during transportation, greatly improving the efficiency and convenience of mineral screening.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
