Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of belt scraping devices, and more specifically, to a return scraping device for a high-moisture bauxite feed belt. Background Technology

[0002] High-moisture bauxite, due to its high temperature and moisture content, significantly increases the difficulty of mining and causticizing operations. To ensure the safety and efficiency of both mining and causticizing processes, special protective measures and technical methods must be employed. The causticizing process for high-moisture bauxite includes crushing, grinding, flotation, and dewatering, with each process connected by a conveyor system. The feeding efficiency of this conveyor system has a significant impact on the bauxite causticizing yield and effectiveness.

[0003] A conveying device typically consists of a motor or internal combustion engine, chains, gears, couplings, clutches, conveyor belts, and a frame base. The power source outputs power to drive the gears, which in turn drive the conveyor belt via the coupling to unload the material. However, when conveying high-moisture bauxite, its high moisture content causes the ore to easily adhere to the conveyor belt, preventing some of the ore from smoothly entering subsequent processing steps and resulting in resource waste.

[0004] To address the adhesion problem of high-moisture bauxite, methods such as using desiccant to reduce the moisture content of the ore, replacing belt materials with those having better anti-adhesion properties, and coating the conveyor belt with anti-adhesion agents have been proposed and have achieved some success. However, in actual production, these methods have high material replacement costs. Therefore, a fixed scraper is generally used to scrape off the high-moisture bauxite adhering to the belt during the belt return trip.

[0005] Even if the scraper can remove the attached ore, when the ore is lifted by a belt conveyor, if it only scrapes off the ore, then in the subsequent process, the large amount of ore that has been scraped off still needs to be rearranged back to the starting point of the belt to be transported to the specified height, or the collection box that collects the large amount of scraped-off ore can be directly lifted to the specified height. Moreover, the functionality of scraping needs to be improved. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide a return scraping device for a high-moisture bauxite feed belt, which solves the technical problem in the related art that when using a belt to lift high-moisture bauxite, the ore scraped off by the scraper needs to be lifted to a specified height by additional actions, resulting in time-consuming and labor-intensive work.

[0007] According to one aspect, at least one embodiment of this disclosure provides a return scraper for a high-moisture bauxite feed belt, comprising:

[0008] support;

[0009] A circulating belt, which is inclinedly mounted on the support and has a discharge end, is used to lift the ore to the discharge end after circulation;

[0010] A scraper, one end of which abuts against the bottom surface of the circulating belt and is disposed adjacent to the discharge end, forming a storage area between itself and the support, is used to scrape the ore on the circulating belt to the storage area. The scraper is reciprocatingly mounted on the support and is configured to move closer to the discharge end after moving, so that the scraped ore leaves the storage area.

[0011] For example, the return scraper of the high-moisture bauxite feed belt provided in at least one embodiment of this disclosure further includes:

[0012] The bracket is detachably connected to a support platform for moving the scraper. The material storage area is formed between the support platform and the scraper, and both the support platform and the circulation belt are set at an angle to the scraper.

[0013] For example, the return scraper of the high-moisture bauxite feed belt provided in at least one embodiment of this disclosure further includes:

[0014] Two material blocking sections are symmetrically arranged on both sides of the support platform. Each material blocking section has a material blocking inclined surface. The material storage area is formed between the material blocking inclined surface, the support platform, and the scraper. The scraper abuts against the two material blocking inclined surfaces on both sides.

[0015] For example, the return scraper of the high-moisture bauxite feed belt provided in at least one embodiment of this disclosure further includes:

[0016] A brush roller is rotatably connected to the side of the scraper away from the storage area, and the brush roller is used to clean the circulation belt.

[0017] For example, the return scraper of the high-moisture bauxite feed belt provided in at least one embodiment of this disclosure further includes:

[0018] A pressure plate is mounted on the support, located inside the inner ring of the circulating belt and above the scraper, and abuts against the circulating belt to provide a pressure force to the scraper so that the scraper scrapes off the ore on the circulating belt.

[0019] For example, the return scraper of the high-moisture bauxite feed belt provided in at least one embodiment of this disclosure further includes:

[0020] A support is detachably connected to the support frame. The pressure plate is raised and lowered relative to the support frame and is raised and lowered on the support frame. The scraper is configured to move and lift the pressure plate so that the scraper scrapes off the ore on the circulation belt.

[0021] For example, the return scraper of the high-moisture bauxite feed belt provided in at least one embodiment of this disclosure further includes:

[0022] A top material plate is raised and lowered on the support, located inside the inner ring of the circulation belt, and adjacent to the discharge end. The top material plate is configured to lift the circulation belt after rising, so that the ore is removed from the circulation belt.

[0023] For example, the return scraper of the high-moisture bauxite feed belt provided in at least one embodiment of this disclosure further includes:

[0024] Two baffles are respectively provided on both sides of the top material plate. The baffles are set at an acute angle to the top material plate to prevent the ore from splashing. The circulation belt is located between the two baffles.

[0025] For example, the return scraper of the high-moisture bauxite feed belt provided in at least one embodiment of this disclosure further includes:

[0026] A heating rod is provided on the scraper, and the heating rod is located in the storage area.

[0027] For example, the return scraper of the high-moisture bauxite feed belt provided in at least one embodiment of this disclosure further includes:

[0028] There are several heating rods, and the heating rods are arranged in a matrix.

[0029] The beneficial effects of the embodiments disclosed herein are as follows:

[0030] In this disclosure, an inclined circulating belt is set up to transport the ore to the discharge end at a specified height by means of the lifting effect of the circulating belt. The scraper is in close contact with the bottom surface of the circulating belt. When the circulating belt returns, the scraper scrapes off the ore that is attached to the circulating belt. The scraped-off ore is temporarily stored in the storage area.

[0031] When the scraper moves close to the discharge end, the ore in the storage area can be directly removed from the storage area along with the movement of the scraper and enter the subsequent processing flow corresponding to the discharge end. This design makes full use of the transportation function of the circulating belt and the scraping function of the scraper, realizing the integration of ore scraping and conveying, and simplifying the process flow.

[0042] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0043] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product.

[0047] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0048] like Figures 1-4 The diagram illustrates a return scraping device for a high-moisture bauxite feed belt according to an embodiment of the present disclosure. The device includes: a circulating belt 2 inclinedly mounted on a support 1, having a discharge end 201 for lifting ore to the discharge end 201 after circulation; a scraper 3 with one end abutting against the bottom surface of the circulating belt 2, adjacent to the discharge end 201, forming a storage area 4 between itself and the support 1, for scraping ore from the circulating belt 2 to the storage area 4; the scraper 3 is reciprocatingly mounted on the support 1, and configured to move closer to the discharge end 201 after movement, so that the scraped ore leaves the storage area 4.

[0049] First, the support frame 1 serves as the supporting structure for the entire device. The installation position of the support frame 1 is determined on the ground, and the base of the support frame 1 is fixed to the ground using anchor bolts. It is made of high-strength steel and has sufficient strength and stability. Second, a circulating belt 2 (belt) is inclinedly arranged on the support frame 1. The upper end for discharging material is the discharge end 201, and the lower end for receiving material is the receiving end. The receiving end and the discharge end 201 can be connected to the drive motor through a transmission wheel. By controlling the speed and direction of the motor, the stable operation of the circulating belt 2 and the efficient lifting of the ore can be achieved.

[0050] The scraper 3 moves back and forth on the support 1 and abuts against the bottom surface of the circulating belt 2. It is also adjacent to the discharge end 201. During the normal circulation of the circulating belt 2, the scraper 3 can scrape off the mineral material adhering to the circulating belt 2 and move it to the storage area 4 while the storage area 4 is stationary. When the storage area 4 has stored a certain amount of mineral material, the scraper 3 is moved closer to the discharge end 201 by the drive device (cylinder, etc.) so that the scraped mineral material is removed from the storage area 4 and directly enters the subsequent processing flow. After that, it can be reset. This avoids the cumbersome operation of rearranging the scraped mineral material back to the belt starting point or lifting the collection box in the traditional method.

[0051] Specifically, the scraper 3 can be mounted on the bracket 1 via a linear guide rail, and the scraper 3 is fixedly connected to the slider of the sliding guide rail. During the installation process, it is ensured that the scraper 3 is in close contact with the bottom surface of the circulating belt 2, and the cutting edge of the scraper 3 is set perpendicular to or at an obtuse angle to the running direction of the circulating belt 2 to ensure the scraping effect.

[0052] The scraping device disclosed herein avoids the cumbersome post-processing of scraping off ore in traditional methods. After scraping, the ore can directly enter the subsequent process, greatly shortening the production cycle and improving the overall production efficiency. In addition, the reciprocating movement design of the scraper 3 not only pushes the scraped ore towards the discharge end 201 after reciprocating movement, so that it can enter the subsequent process together, but also can adapt to high-moisture bauxite with different humidity and adhesion levels by controlling the movement frequency and position of the scraper 3. For example, when the ore has high humidity and severe adhesion, the movement frequency of the scraper 3 can be increased within a certain range, instead of just fixing it in a certain position to scrape the ore. Finally, after the storage area 4 is full of ore, it is controlled to move closer to the discharge end 201.

[0053] like Figures 1-4 As shown, in some examples, a support platform 5 for moving the scraper 3 is detachably connected to the bracket 1. A material storage area 4 is formed between the support platform 5 and the scraper 3, and both the support platform 5 and the circulation belt 2 are set at an angle to the scraper 3.

[0054] A detachable support platform 5 is provided to support the scraper 3 under various conditions. This can be achieved by adjusting the position and angle of the support platform 5. The detachable method is usually bolt connection. Since the adhesion of the ore on the circulation belt 2 is not uniform, the circulation belt 2 and the scraper 3 are set at an angle (rather than perpendicular). This allows the scraper 3 to scrape off the attached ore more thoroughly. In traditional scraping devices, if the scraper 3 is set perpendicular to the circulation belt 2, the scraper 3 is mostly used to "block" the ore. However, the angle is usually an obtuse angle of 120° to 150°. This means that the scraper 3 is mostly used to "scrape off" the ore. The blade of the scraper 3 can cut into the attached ore from the bottom at an inclined angle, causing it to fall directly into the storage area 4, or gradually slide down the surface of the scraper 3 into the storage area 4. This scraping is more stable and is more suitable for the high humidity and easy adhesion characteristics of high-moisture bauxite.

[0055] The angle formed by the support platform 5 and the scraper 3 is mainly to accommodate the inclined circulation belt 2 and the scraper 3 at the same angle, providing stable support for the inclined reciprocating movement path of the scraper 3, preventing the scraper 3 from moving away from the circulation belt 2 in a vertical state. At the same time, it also allows the bottom of the storage area 4 formed by the two to have a certain slope, so that the scraped ore can be more stably accumulated from the bottom up, stably "holding" the ore and preventing it from being missed.

[0056] like Figures 1-4 , Figure 7 , Figure 8 As shown, in some examples, two baffles 501 are symmetrically arranged on both sides of the support platform 5. The baffles 501 have baffle slopes 502. A storage area 4 is formed between the baffle slopes 502, the support platform 5 and the scraper 3. The two sides of the scraper 3 abut against the two baffle slopes 502 respectively.

[0057] The symmetrical, integrally formed or welded baffles 501 on both sides of the support platform 5 can prevent the scraped ore from falling from both sides of the support platform 5 using their baffle slopes 502, and guide the scraped ore to always gather in the middle of the storage area 4, accumulating from the bottom up under the action of the slope. At the same time, compared with the flat support without baffles 501, the baffle slopes 502 make the storage area 4 have a trapezoidal cross section, which can accommodate more ore in a limited space.

[0058] The material blocking part 501 is generally triangular in shape. The side closest to the center of the support platform 5 is the material blocking inclined surface 502. The angle between the material blocking inclined surface 502 and the plane of the support platform 5 is usually between 30° and 60°. This angle range can effectively guide the ore to gather in the middle of the storage area 4, and will not affect the space of the storage area 4 due to the angle being too large or the material blocking effect being poor due to the angle being too small.

[0059] The main body of the scraper 3 is a rectangular flat plate, and its length is slightly greater than the width of the circulation belt 2, ensuring that it can cover the entire width of the circulation belt 2 for scraping. The protruding part of the two sides of the scraper 3 is in close contact with the material blocking inclined surface 502, so that the guiding effect of the material blocking inclined surface 502 can be maximized during the movement of the scraper 3.

[0060] like Figure 5 As shown, in some examples, a brush roller 6 is rotatably connected to the side of the scraper 3 away from the storage area 4. The brush roller 6 is used to clean the circulating belt 2.

[0061] To enhance the cleaning effect, a brush roller 6 is rotated and connected on the side of the scraper 3 away from the storage area 4. After the high-moisture bauxite adheres to the circulating belt 2, simply relying on the scraper 3 to remove it may leave some fine particles or sticky ore traces. However, the bristles of the brush roller 6 can directly clean these residual ore after the scraper 3 is applied, providing a cleaner surface for the subsequent transportation of new ore and facilitating subsequent conveying.

[0062] For specific rotating connections, such as the brush roller 6 being directly mounted on the scraper 3 via bearings, the brush roller 6 is driven to rotate by the friction between the circulating belt 2 and the surface of the brush roller 6 during the operation of the circulating belt 2. However, this is suitable for situations where the speed of the circulating belt 2 is relatively stable and the cleaning requirements are not particularly high. Alternatively, the brush roller 6 can be actively driven to rotate by installing a small motor on the scraper 3 or connecting an external power source.

[0063] like Figures 1-5 As shown, in some examples, the return scraping device of the high-moisture bauxite feed belt further includes: a pressure plate 7 is set on the support 1, located inside the inner ring of the circulating belt 2, and above the scraper 3, and abuts against the circulating belt 2, for providing a pressure force to the scraper 3 so that the scraper 3 scrapes off the ore on the circulating belt 2.

[0064] To improve the scraping effect, the pressure table 7 is positioned above the scraper 3 on the inner ring of the circulating belt 2. Its main function is to provide additional pressure to the scraper 3, ensuring that the scraper 3 can fit more tightly against the surface of the circulating belt 2, thereby more effectively scraping off the high-moisture bauxite material adhering to the circulating belt 2. This prevents the circulating belt 2 from deteriorating in tension after long-term use, when it is inconvenient to adjust the tension in time, which would cause the scraping effect of the scraper 3 to gradually weaken. The setting of the pressure table 7 can eliminate the step of adjusting the tension, allowing the circulating belt 2 to continue to transport normally while ensuring the scraping effect of the scraper 3.

[0065] Specifically, the central axis of the pressure table 7 is parallel to the moving direction of the scraper 3. Under the above conditions, it is installed on the bracket 1 by bolts to ensure that the pressure is applied evenly to the scraper 3. With bolts, the installation position and angle of the pressure table 7 can be adjusted by pre-drilling corresponding bolt holes on the bracket 1 and the pressure table 7.

[0066] like Figures 1-5 As shown, in some examples, a support 8 is detachably connected to the support 1, and a pressing platform 7 is raised and lowered relative to the support 1 and raised and lowered on the support 8. The scraper 3 is configured to move and lift the pressing platform 7 so that the scraper 3 scrapes off the ore on the circulating belt 2.

[0067] The detachable support 8 on the bracket 1 enables the pressure platform 7 to be passively raised and lowered, while also adapting to the adjustment of the installation position of the pressure platform 7. This design enhances the scraping effect, that is, the scraper 3 supports the pressure platform 7, and after its movement, the pressure platform 7 is lifted, so that the pressure platform 7 provides additional pressure in the critical scraping stage. That is, the weight 1 of the pressure platform 7 is fully applied to the scraper 3, rather than in the case of a fixed position, part of the weight is borne by the bracket 1, ensuring that the scraper 3 can scrape the ore more thoroughly.

[0068] In addition, under normal installation conditions, it is difficult to ensure that the central axis of the pressure table 7 is precisely parallel to the moving direction of the scraper 3, so that the pressure table 7 can stably provide pressure to the scraper 3. Therefore, the above-mentioned form is improved to facilitate the early production and installation. The top of the scraper 3 can stably support the lowest position of the pressure table 7.

[0069] Specifically, the pressure plate 7 is usually arranged adjacent to the discharge end 201 and covers a certain area of ​​the circulation belt 2 to ensure that it continuously provides force to the scraper 3. Therefore, several corresponding supports 8 can be arranged along its length to ensure that the pressure plate 7 can be raised and lowered stably as a whole. Furthermore, several supports 8 are detachably connected to the bracket 1 by bolts. Each support 8 has a lifting groove. The pressure plate 7 has protrusions integrally formed on both sides, and the protrusions slide in the lifting groove.

[0070] like Figure 6 As shown, in some examples, the return scraper of the high-moisture bauxite feed belt further includes: a top plate 9 is lifted and mounted on the support 1, located in the inner circle of the circulating belt 2, and adjacent to the discharge end 201. The top plate 9 is configured to lift the circulating belt 2 after rising, so that the ore is removed from the circulating belt 2.

[0071] To accelerate the ore removal and reduce ore residue on the circulation belt 2, the top plate 9 is set on the support 1 of the inner ring of the circulation belt 2 and close to the discharge end 201. When the top plate 9 rises, it lifts the circulation belt 2 and changes the local shape of the circulation belt 2, so that the ore before discharge is lifted off the circulation belt 2 and enters the next process. Compared with the traditional method of detaching from the circulation belt 2 by its own weight, the ore can be subjected to additional force, which is more conducive to detaching from the circulation belt 2.

[0072] The top plate 9 can be designed to be an arc shape that matches the inner curvature of the circulating belt 2, so as to ensure that it can act evenly on the circulating belt 2 during the lifting process and avoid excessive local stress that could damage the circulating belt 2. The lifting and lowering of the top plate 9 is controlled by a drive device, and common drive devices include electric push rods and hydraulic cylinders.

[0073] The top plate 9 is installed on the bracket 1 near the discharge end 201, which can produce the best separation effect on the ore near the discharge end 201.

[0074] like Figure 6 As shown, in some examples, two baffles 10 are respectively provided on both sides of the top plate 9. The two baffles 10 are symmetrically arranged and the baffles 10 are set at an acute angle to the top plate 9 to prevent the ore from splashing. The circulation belt 2 is located between the two baffles 10.

[0075] During the process of the top plate 9 lifting the circulation belt 2, the ore is subjected to additional force generated by the deformation of the circulation belt 2, which makes it easy to splash off the circulation belt 2. To avoid the above situation, two baffles 10 are symmetrically arranged on the top plate 9, which are set at an acute angle to the top plate 9 to form a protective area.

[0076] The baffle 10 can be in the shape of a right-angled trapezoid or a straight plate, and is fixed to the top plate 9 by bolts or welding. When bolted, corresponding bolt holes are pre-drilled on the baffle 10 and the top plate 9, and high-strength bolts are used to fasten the two together. This method facilitates installation and disassembly, and allows for quick operation when the baffle 10 needs to be replaced or the equipment needs maintenance.

[0077] like Figures 7-8 As shown, in some examples, a heating rod 11 is provided on the scraper 3, and the heating rod 11 is located in the storage area 4; there are several heating rods 11, and the several heating rods 11 are arranged along a matrix.

[0078] High-moisture bauxite has a high water content and high viscosity, making it easy to adhere to the scraper 3 or support platform 5. Therefore, the heating rod 11 installed on the scraper 3 can generate heat to continuously heat the ore in the storage area 4. The heat is transferred to the ore, causing its moisture to evaporate, thereby reducing the viscosity of the ore and reducing the workload of subsequent drying and dehydration. In addition, the heat in the storage area 4 can also act on the return circulation belt 2 to a certain extent, making it easier to scrape off the ore.

[0079] Specifically, the heating rod 11 uses a resistance wire as the heating element. When current passes through the resistance wire, the resistance wire generates Joule heat, which can stably heat up under long-term power supply. In addition, there are several heating rods 11 arranged along a matrix. This layout can heat the ore in the storage area 4 more evenly, or according to the distribution and viscosity difference of the ore in the storage area 4, such as the upper layer being wetter and the lower layer being drier, the heating rods 11 at different positions can be controlled separately to achieve precise heating.

[0080] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications or substitutions should be covered within the scope of the claims of this disclosure.
