Description

Technical Field

[0001] The utility model relates to the technical field of rubber products and mining engineering, in particular to a rubber belt. Background Art

[0002] With the increasing amount of iron ore mining, the amount of lean magnetite ore and ultra-lean magnetite ore being selected is increasing. Before the magnetite ore enters the mill, a pre-dry selection process is usually used to discard the waste, so as to improve the grade of the ore entering the mill and reduce the production cost of ore dressing.

[0003] At present, the commonly used dry separation process is fine ore dry separation, that is, the fine ore under the screen of the closed-circuit crushing and screening operation is dry separated to obtain dry separation concentrate and dry separation waste rock. The dry separation concentrate is used as the ore to be ground, and the dry separation waste rock is discarded. The dry separation machine mainly includes a magnetic pulley or a CT magnetic drum or a CTDG magnetic drum or a CTX magnetic drum. The magnetic pulley has a 360° magnetic system and is fixed and rotates synchronously with the outer cylinder. There is no magnetic reversal and serious inclusions. It has been eliminated in the field of magnetite ore sorting. The magnetic system of the CT magnetic drum or CTDG magnetic drum is fixed, the magnetic system wrap angle is about 170°, the magnetic field strength on the drum surface is 0.2~0.6T, the belt conveying speed is 1.2~2.5m / s, and the magnetic reversal times of the magnetic particles during dry sorting are small, resulting in the inclusion of waste rock in the dry sorting concentrate, and the inclusion of magnetite ore in the dry sorting waste rock, resulting in poor dry sorting effect. The magnetic system wrap angle of the CTX magnetic drum is 360°, the magnetic field strength on the outer cylinder surface is ≥0.4T, the sorting belt speed is ≥2.5m / s, the magnetic system rotation speed is ≥80r / min, and the outer cylinder and the magnetic system rotate in the opposite direction. Rotate to form a rotating magnetic field. When the magnetic ore particles pass through, rapid magnetic reversal and magnetic stirring occur in the magnetic pole alternation area. Under the combined action of magnetic field force, centrifugal force and gravity, the non-(weakly) magnetic waste rock particles mixed between the magnetic ore particles will move to the outer layer due to magnetic stirring, while the magnetic ore particles mixed between the non-(weakly) magnetic waste rock particles will move to the inner layer due to the strong magnetic field force, thereby realizing efficient separation of magnetic ore particles and non-(weakly) magnetic waste rock particles, and being able to fully discard the non-(weakly) magnetic waste rock particles mixed between the magnetic ore particles. The obtained dry separation concentrate has a high grade and the dry separation waste rock has a low grade, that is, the qualified dry separation waste yield is high and the sorting effect is good.

[0004] The CTX magnetic drum can discard a large amount of qualified waste rock, which can reduce the cost of grinding and sorting, thereby significantly reducing the production cost of mineral processing, reducing the amount of fine tailings entering the tailings pond, and increasing the service life of the tailings pond. The coarse waste rock has a high utilization value, thereby achieving cost reduction and efficiency improvement in the mineral processing plant.

[0005] In the existing mineral processing plants, because there is no synchronous design and construction of the dry separation system, the production and transformation space is small, and only the CTX dry separation machine with a short belt can be used; or the separation belt used by the dry separation machine is too long, or the belt running obliquely on the dry separation machine is too long and the installation angle is too large, which makes it unsuitable to use the CTX magnetic drum for direct dry separation upgrade and transformation, and only the CTX dry separation machine with a short belt can be used under the machine head (including the machine head which is a conventional transmission drum or CT magnetic drum or CTDG magnetic drum); in the newly built mineral processing plants, in order to save the floor space of the dry separation machine and to reduce the length of the separation belt of the dry separation machine, so as to facilitate the collection of dry separation concentrate and dry separation tailings, it is suitable to use the CTX dry separation machine with a short belt.

[0006] In the relevant technical field, the existing short belt CTX dry separator has the problem that the pre-bonded ring belt is inconvenient to install when the ring rubber belt is installed or repaired, and the ring belt needs to be replaced after being damaged. Replacing the ring belt requires a long time to disassemble the CTX dry separator, and a large space is required to install the ring belt, and it takes a long time to restore the CTX dry separator.

[0041] The utility model provides a rubber belt.

[0042] In the embodiment of the present utility model, Figures 1 to 4As shown, the rubber belt 10 includes a tape body 100, and the tape body 100 has a first end 110 and a second end 120 that are relatively arranged along its own length direction. The first end 110 and the second end 120 have a working surface 130 and a non-working surface 140 that are relatively arranged. The working surface 130 is suitable for being arranged outward after the tape body 100 is enclosed and bonded, and the non-working surface 140 is suitable for being arranged inward after the tape body 100 is enclosed and bonded; wherein, a first bonding area 150 is provided on the non-working surface 140 of the first end 110, and a second bonding area 160 is provided on the working surface 130 of the second end 120, and a plurality of connecting protrusions 151 are provided on the first bonding area 150, and a plurality of connecting hole portions 161 are provided in the second bonding area 160 corresponding to the connecting protrusions 151. When the tape body 100 is enclosed and bonded, the connecting protrusions 151 and the connecting hole portions 161 are aligned and overlapped.

[0043] The present application provides a first bonding area 150 and a second bonding area 160 on the working surface 130 and the non-working surface 140 at both ends of the tape body 100, wherein the first bonding area 150 is provided with a plurality of connecting protrusions 151, and the second bonding area 160 is provided with connecting holes 161 corresponding to the connecting protrusions 151, and the connecting protrusions 151 are aligned and overlapped with the connecting holes 161, so that after the tape body 100 is enclosed and bonded, the original rubber tape 10 retained by the tape body 100 is bonded. The block serves as a connecting protrusion 151, and the connecting protrusion 151 and the rubber belt 10 are an integral structure. The bonding strength is the same as that of the original rubber belt 10, which is more than 20% higher than the bonding strength of the same area of ​​the bonding section, ensuring the bonding strength of the bonding section of the rubber belt 10. Therefore, under the premise of ensuring the bonding strength of the rubber belt 10, the length of the bonding joint can be effectively reduced, the space required for bonding can be reduced, in-situ bonding can be achieved, the installation and maintenance efficiency of the CTX dry sorting machine can be greatly improved, and the bonding of the rubber belt 10 in a narrow space can be easily achieved.

[0044] At the same time, the bonding interface on the working surface 130 of the bonding area of ​​the rubber belt 10 is behind the running direction of the belt to prevent the material transported on the surface of the belt from scratching the bonding interface of the rubber belt 10; the connecting protrusion 151 on the first bonding area 150 of the rubber belt 10 is set toward the non-working surface 140 to avoid friction and scratching of the material transported on the surface of the belt.

[0045] Reference Figure 2 According to an embodiment provided by the utility model, the first bonding area 150 is an inner step surface formed by the non-working surface 140 of the first end 110 being recessed toward the working surface 130, and the connecting protrusion 151 is arranged on the inner step surface. The second bonding area 160 is an outer step surface formed by the working surface 130 of the second end 120 being recessed toward the non-working surface 140, and the connecting hole portion 161 passes through the outer step surface and the non-working surface 140.

[0046] It can be understood that in this embodiment, the inner step surface and the outer step surface corresponding to the first bonding area 150 and the second bonding area 160 are formed by recessing the docking position of the first end 110 and the second end 120, so as to facilitate the flush connection between the working surface 130 and the non-working surface 140. At the same time, the first bonding area 150 forms a relatively independent and stable platform at the end of the first end 110. The stability and strength of the bonding area are increased, and it is also helpful to reduce the potential impact on the working surface 130 during the bonding process. At the same time, the inner step surface also provides enough space to accommodate the connecting protrusion 151, making the bonding operation smoother and more accurate. Corresponding to the inner step surface, the outer step surface is recessed inward from the working surface 130 for the second end 120, forming an easy-to-operate bonding platform. It makes it easier to locate and fix the connecting hole portion 161 during the bonding process. The connecting protrusion 151 arranged on the inner step surface is a key part of the mechanical lock, which can ensure that it is accurately docked with the connecting hole portion 161 of the second end 120 when the tape is enclosed and firmly locked. The presence of the connecting protrusion 151 improves the strength and durability of the bonding by means of physical locking.

[0047] Reference Figure 3 and Figure 4 According to an embodiment of the present invention, a plurality of connecting protrusions 151 are arranged in multiple rows along the length direction of the tape body 100, two adjacent rows of connecting protrusions 151 are staggered, and two alternate rows of connecting protrusions 151 are co-located.

[0048] It is understandable that, in this embodiment, by staggering the two adjacent rows of connecting protrusions 151, when the adhesive tape is subjected to external force, the stress can be more evenly distributed on multiple connection points. This helps to reduce the concentrated stress on a single connection point, thereby improving the strength and stability of the entire bonding area. The staggered connecting protrusions 151 and the connecting holes 161 can disperse the tensile stress, so that the adhesive tape is subjected to more uniform force in the bonding area, which helps to prevent the adhesive tape from deviating and prolong the service life of the adhesive tape.

[0049] The connecting protrusions 151 are arranged in multiple rows along the length direction, and are arranged in an adjacent staggered and alternately co-located manner, so that more connection points can be achieved within a limited tape bonding area. The tensile stresses on the tape connecting protrusions 151 and the connecting holes 161 at each connection point are relatively balanced and consistent, which helps to reduce the space required for the bonding area, making the design of the tape bonding area more flexible and efficient.

[0050] Optionally, a plurality of connecting protrusions 151 are arranged in multiple rows along the length direction of the tape body 100 , and the number of rows is m, where m is greater than or equal to 1. The arrangement can be made according to specific needs and is not particularly limited herein.

[0051] Reference Figure 3According to an embodiment of the present invention, the side length a of the connecting protrusion 151 extending along the width direction of the tape body 100 is greater than or equal to 20 mm and less than or equal to 200 mm.

[0052] It is understandable that the minimum value of 20mm for the side length a of the connecting protrusion 151 ensures that the connecting protrusion 151 can withstand sufficient tensile stress during the operation of the tape, maintain the firmness and stability of the tape adhesion, and prevent the interface from breaking when the tape is running at high speed or under high tension. Although the connecting protrusion 151 with a larger side length a can provide a stronger mechanical locking effect and better tensile stress bearing capacity, an excessively large side length a of the connecting protrusion 151 will reduce the remaining net width of the tape in the second bonding area 160 where the tape connection hole portion 161 is located or the net width of the tape between the connection hole portions 161, thereby reducing the inherent tensile strength of the second bonding area of ​​the tape. According to the TD type tape used in conjunction with the CTX dry sorting machine, the width B=600-4000mm is generally used, and the maximum value of the side length a should not exceed 200mm.

[0053] According to an embodiment of the present invention, the calculation formula between the number n of each row of connecting protrusions 151 and the width B of the tape body 100 is:

[0054] n≤B÷3a, n is an integer;

[0055] Wherein: B is the width of the tape, in mm; a is the side length of the connecting protrusion 151 extending along the width direction of the tape body 100, in mm.

[0056] It can be understood that the number n of the connecting protrusions 151 in each row is positively correlated with the width B of the tape body 100. The wider the width B of the tape body 100, the greater the number n of the connecting protrusions 151 in each row that needs to be set. Since the connecting protrusions 151 between two adjacent rows are arranged in a staggered manner, 3a represents the total length of the side length of the connecting protrusion 151 and the minimum width of the remaining tape in the horizontal direction of the corresponding connecting hole portion 161 reserved on both sides. If n=1, it means that a connecting protrusion 151 is made at the center of the width of the tape, and a certain space is reserved on both sides of the connecting protrusion 151, so that the corresponding width of the tape is reserved on both sides of the connecting hole portion 161 that cooperates with it to provide sufficient tension for the tape. At the same time, the tape has sufficient edge width to ensure that there is sufficient space for the integrity of the tape during the production, bonding and use of the tape bonding area, to ensure that the connecting protrusion 151 and the connecting hole portion 161 are aligned, and to ensure that the wear resistance of the tape edge is not lost. Since the number of the connecting protrusions 151 must be an integer, even if the calculated result is not an integer, it needs to be rounded down to the nearest integer.

[0057] According to an embodiment of the present invention, the calculation formula between the number of rows m of the connecting protrusions 151 and the distance L of the first adhesive area 150 extending along the length direction of the tape body 100 is:

[0058] m≤L÷2.5b, m is an integer;

[0059] Wherein: L is the adhesive length of the tape, in mm; b is the side length of the connecting protrusion 151 extending along the length direction of the tape body 100, in mm.

[0060] It can be understood that in this embodiment, the number of rows m of the connecting protrusions 151 is positively correlated with the distance L of the first adhesive area 150 extending along the length direction of the tape body 100. The longer the distance L of the first adhesive area 150 extending along the length direction of the tape body 100, the greater the number of rows m that need to be set. In order to ensure the effectiveness of the connection of the connecting hole portion 161 to each connecting protrusion 151, a spacing is set between each row of connecting protrusions 151, and each row of connecting protrusions 151 is set at a certain distance from the outer peripheral side of the first adhesive area 150. Therefore, within a given length L, the number of rows can be determined by the ratio between L and 2.5b, but since the number of rows must be an integer, the actual number of rows m should be less than or equal to this calculation result and rounded down.

[0061] The distance L of the first adhesive area 150 extending along the length direction of the tape body 100 can be calculated by the following formula:

[0062] L≤R×π-40, unit: mm:

[0063] Wherein: R is the radius of the outer cylinder of the CTX magnetic drum 20, in mm; π is the pi.

[0064] Reference Figure 3 and Figure 4 According to an embodiment of the present invention, the connecting protrusion 151 is a square protrusion, and the outer edge of at least one side of the square protrusion is arranged parallel to the end surface of the first end 110.

[0065] It is understandable that the square protrusion provides better structural stability due to its characteristics of equal length of four sides and equal size of four corners. When the tape is subjected to tension or other external forces, it helps to disperse stress and reduce local stress concentration, thereby improving the overall strength and durability of the tape. Since the outer edge is parallel to the end face of the first end 110 of the tape, it is convenient to position and fix during the installation process, reducing the difficulty of installation. When the square protrusion cooperates with the corresponding connecting hole portion 161 or the bonding surface, its flat side and regular edges help to form a closer contact and a more uniform bonding layer. This close contact can improve the firmness and reliability of the bonding and reduce the risk of falling off or loosening during use.

[0066] Reference Figure 3 According to an embodiment of the present invention, the shortest distance between the connecting protrusion 151 or the connecting hole 161 and the end surface of the first end 110 or the end surface of the second end 120 is D, where D is greater than or equal to 20 mm.

[0067] It is understandable that maintaining a certain distance D between the connecting protrusion 151 or the connecting hole 161 and the end surface can effectively avoid damage or breakage caused by stress concentration at the end surface during use of the adhesive tape.

[0068] According to an embodiment of the present invention, the cross-sectional shape of the connecting protrusion 151 includes any one of a triangle, a square, a trapezoid or a sector.

[0069] It is understandable that the cross-sectional shape of the connecting protrusion 151 can be any regular shape such as an isosceles triangle, an equilateral triangle, a square, a rectangle, an isosceles trapezoid, etc., and can be set according to specific needs and is not particularly limited here.

[0070] Reference Figure 3 and Figure 4 According to an embodiment of the present invention, a plurality of connection protrusions 151 or a plurality of connection holes 161 are symmetrically arranged about a center line of the length direction of the tape body 100 .

[0071] It is understandable that the symmetrically arranged connection protrusions 151 or connection holes 161 help maintain the balance of the tape when subjected to force. When the tape is subjected to external loads, the symmetrical arrangement can ensure that the force is distributed more evenly on the tape, thereby reducing the risk of damage caused by local stress concentration, and is also conducive to ensuring that the tape does not deviate.

[0072] Reference Figure 1 and Figure 5 In one embodiment, the rubber belt 10 is spread around the circumference of the driving roller 30 and the CTX magnetic roller 20, and an arc-shaped carbon steel pressing plate 40 with a radius that is half the outer diameter of the outer cylinder of the CTX magnetic roller 20 and the thickness of the tape is used. The bonding part of the rubber belt 10 is pressed with the help of the magnetic field force of the magnetic system of the CTX magnetic roller 20, and then the arc-shaped carbon steel pressing plate 40 is heated by an iodine tungsten lamp heating tool, and the temperature is controlled not to exceed 145°C, and the insulation time is 30 minutes; the iodine tungsten lamp heating tool is turned off, and the arc-shaped carbon steel pressing plate 40 and the adhesive tape are naturally cooled to room temperature, and the arc-shaped carbon steel pressing plate 40 is removed; the bonding part of the rubber belt 10 is trimmed to be flat and smooth, and it can be used after 2 hours.
