Description

Technical Field

[0001] This utility model relates to the field of graded fabric distribution technology, and in particular to a segregating fabric distributor and an intelligent dry separation system. Background Technology

[0002] Intelligent dry separators have specific requirements regarding the feed particle size in practical applications. Generally, based on particle size, materials can be categorized into three sizes: large (300-50mm), medium (100-25mm), and small (40-10mm). When the particle size distribution of the incoming material is wide, such as between 300-25mm, directly processing it with a single device and mixing materials of different sizes into the dry separator can easily lead to large particles pressing down on or obscuring smaller particles during the feeding process. This prevents the small particles from being effectively identified and sorted, thus affecting the overall sorting accuracy and efficiency.

[0003] To address the aforementioned issues, existing technologies typically require multiple intelligent dry separators to process materials of different particle sizes, increasing equipment investment and operating costs. Therefore, a new solution is urgently needed that, without increasing the number of machines, achieves effective classification of wide-range materials through a rational screening and material distribution structure design. Furthermore, it should enable a single intelligent dry separator to simultaneously process two different particle size ranges, thereby improving equipment utilization, expanding its applicability, and achieving the goal of multi-functionality.

[0039] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0040] like Figures 1 to 4As shown, this utility model embodiment provides a separation material distributor, which includes: a main body 1, a drive source 4, a multi-stage screen 2, and a material distribution plate 3 corresponding to each screen 2. The main body 1 is the main frame of the separation material distributor, with a U-shaped cross-section, including two opposing side plates and a back plate connecting the two side plates. The screens 2 and the material distribution plates 3 are both fixedly installed inside the main body 1. The "semi-enclosed" material handling space effectively reduces material splashing and spillage during the screening process of the screens 2 and the distribution process of the material distribution plates 3. The screen 2 includes a screen frame and a screen surface with multiple mesh openings, with the screen surface fixed inside the screen frame. All screens 2 are arranged vertically at intervals on the main body 1 of the equipment, and three of the sides of the screen 2 are respectively connected to two side plates and a back plate. The multi-stage screens 2 can achieve material grading. One end of the material distribution plate 3 is connected to the material discharge end of the screen 2, and the other end of the material distribution plate 3 is connected to the downstream equipment. In use, the material on the screen of each screen 2 leaves the screen 2 and enters the corresponding material distribution plate 3, and is then transported to the downstream equipment through the material distribution plate 3. The material can be distributed and spread on the material distribution plate 3. In order to better match the downstream equipment and to improve the distribution effect, each material distribution plate 3 is located on the same plane. Correspondingly, the material discharge ends of each screen 2 are also located on the same plane. The drive source 4 is connected to the main body 1 of the equipment. The drive source 4 is used to drive the main body 1 of the equipment to vibrate, thereby driving the screen 2 and the material plate 3 connected to the main body 1 of the equipment to vibrate synchronously, so that materials with a particle size smaller than the mesh can pass through the screen 2, materials with a particle size larger than the mesh can move towards the material plate 3, and the materials can be spread and distributed on the material plate 3.

[0041] The separation feeder provided in this embodiment, in use, with the cooperation of the drive source 4 and the multi-stage screens 2, can classify materials according to particle size. The classified materials enter the corresponding feed plates 3. The feed plates 3 corresponding to each screen 2 are located on the same plane, thereby solving the problem of inconsistent material discharge speed caused by the difference in the position of the screens 2. This allows the materials to enter the downstream equipment at the same speed. At the same time, under the action of the drive source 4, the materials can vibrate continuously on the feed plates 3, thereby achieving precise material distribution and spreading effect, further eliminating material accumulation and segregation, and ensuring that the materials enter the downstream equipment in a flat and uniform state.

[0042] In this embodiment, the particle size of the material under the bottom screen 2 is too small to be conveyed to the downstream equipment. A structure such as a conveyor belt can be set below the bottom screen 2 to transport the material under the bottom screen 2 to a designated location or equipment for recycling.

[0043] In an optional implementation, the screen surface of the screen 2 can be formed by multiple screen chords arranged in a crisscross pattern within the screen frame, or it can be a perforated plate, or a combination of both. For example, when the separator feeder is equipped with two layers of screen 2, the screen surface of the upper screen 2 is formed by multiple screen chords arranged in a crisscross pattern within the screen frame, which is mainly used for material grading, while the screen surface of the lower screen 2 is a perforated plate, which is mainly used for powder removal to prevent small-diameter powdery materials from affecting the sorting accuracy.

[0044] Optionally, in this embodiment, the driving source 4 includes a motor drive assembly and a vibrator. The vibrator is connected to the main body 1 of the equipment, and the motor drive assembly is connected to the vibrator in a transmission manner. The motor drive assembly drives the vibrator to run, thereby causing the main body 1 of the equipment to vibrate.

[0045] In this embodiment, when the separator feeder is connected to the multi-channel intelligent dry separator, the material is classified by setting up multi-level screens 2, and at the same time, the feed plate 3 is used to even out the material. This allows the material to enter different channels of the multi-channel intelligent dry separator in multiple particle size grades. The material of the same particle size grade is evenly distributed and has a similar particle size. There will be no phenomenon of large pieces of material pressing down on or blocking small pieces of material. The sorting accuracy and efficiency are effectively improved, and the equipment utilization rate is higher.

[0046] In the optional implementation of this embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, it also includes a material distribution plate 31. The material distribution plate 31 is fixedly disposed between two adjacent material distribution plates 3, thereby separating the two adjacent material distribution plates 3 and preventing the material on one material distribution plate 3 from entering the other material distribution plate 3 and affecting the grading effect of the multi-stage screen on the material.

[0047] In an optional embodiment of this example, each fabric plate 3 has a material distribution plate 31 on its adjacent side. That is, two material distribution plates 31 are provided between two adjacent fabric plates 3, and each material distribution plate 31 is fixed to one of the two fabric plates 3. The side with the material distribution plate 31 is parallel to the material movement direction. Since the particle size of the material passing through each fabric plate 3 is different, the wear degree of each fabric plate 3 varies during use. By separately arranging each fabric plate 3 and providing a material distribution plate 31 on each fabric plate 3, it is convenient to inspect and maintain the fabric plates 3 and the material distribution plates 31. Furthermore, in this embodiment, two adjacent material distribution plates 31 can also be connected by a connecting structure, allowing the two fabric plates 3 to vibrate at the same frequency, improving the fabric distribution effect.

[0048] In this embodiment, when the segregating distributor has two distribution plates 3, a distribution plate 31 is provided on the side of the distribution plate 3 closest to the other distribution plate 3. The side of the distribution plate 3 away from the other distribution plate 3 is connected to the side plate of the equipment body 1. That is, the distribution plate 3, the distribution plate 31, and the side plate of the equipment body 1 together form a discharge channel capable of distributing, evenly distributing, and spreading the material. When the segregating distributor has three distribution plates 3, the distribution plate 31 is provided on the two opposite sides of the distribution plate 3 located in the middle position, and one distribution plate 31 is provided on each of the other two distribution plates 3 located in the remaining positions.

[0049] In an optional embodiment of this example, when there are two material distribution plates 3, a wear-resistant plate can be provided on the side of the material distribution plate 3 away from the material distribution plate 31 to prevent the material from causing wear on the side plate of the main body 1 when it moves on the material distribution plate 3. The wear-resistant plate is detachably fixed to the main body 1 so as to facilitate the replacement of the wear-resistant plate after it is severely worn. When there are three or more material distribution plates 3, a wear-resistant plate can be provided on the side of the material distribution plate 3 away from the material distribution plate 31 at both ends. The wear-resistant plate is also detachably fixed to the side plate of the main body 1 to prevent wear on the side of the main body 1.

[0050] Optionally, in this embodiment, the above-mentioned material distribution plate 31 can be provided on both sides of any one of the material distribution plates 3 along the material movement direction.

[0051] The separation fabric feeder provided in this embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, along the direction of material movement on the screen 2, the screen 2 is divided into a main body section 21 and a shrinking section 22. One end of the shrinking section 22 is connected to the main body section 21, and the other end is connected to the material distribution plate 3. The width of the shrinking section 22 decreases along the direction of material movement on the screen 2, and preferably gradually decreases. The two sides of the main body section 21 parallel to the material movement direction are connected to the two side plates of the main body 1, respectively. The side of the main body section 21 away from the shrinking section 22 is connected to the back plate of the main body 1. By setting the shrinking section 22 to cooperate with the material distribution plate 3, each material distribution plate 3 can be arranged between the two side plates of the main body 1, thereby reducing the width of the separation material distribution device and facilitating the arrangement of the separation material distribution device and its connection with downstream equipment.

[0052] Preferably, in this embodiment, the separation feeder further includes a guide plate 23, which is disposed on the side of the shrinkage section 22 to guide the material onto the feed plate 3, thereby preventing the material from spilling off the shrinkage section 22 when it moves on the shrinkage section 22, thus affecting the production environment and the grading effect of the material.

[0053] In this embodiment, the top view shape of the shrinkage section 22 is generally trapezoidal. When the segregation distributor includes two-stage screens 2, the top view shape of the shrinkage section 22 is a right-angled trapezoid. The right-angled side of the shrinkage section 22 along the material movement direction can be connected to the side plate of the main body 1. In this way, only the guide plate 23 needs to be set on the inclined side of the shrinkage section 22. When the segregation distributor includes three or more stages of screens 2, the shrinkage section 22 located in the middle is not a right-angled trapezoid. In this case, the guide plate 23 mentioned above needs to be set on both inclined sides of this part of the shrinkage section 22 to guide the material flow, thereby preventing the material from spilling from the shrinkage section 22.

[0054] Optionally, in this embodiment, guide plates 23 can be provided on both sides of the contraction section 22 of any screen 2 along the material movement direction. Alternatively, in this embodiment, since the contraction sections 22 located on both sides are in contact with the side plates of the equipment body 1, wear-resistant plates can be provided between the right-angled edge of the contraction section 22 and the side plate to improve wear resistance and prevent the material from damaging the side plates of the equipment body 1 during movement.

[0055] In this embodiment, as mentioned above, a material distribution plate 31 is also fixedly installed on the side of the material distribution plate 3. In order to improve the material flow effect and improve the overall integrity of the equipment, the material guide plate 23 is also connected to the corresponding material distribution plate 31.

[0056] Specifically, in this embodiment, when a guide plate 23 is provided on the inclined side of each shrinkage section 22, and a distribution plate 31 is provided on the side adjacent to each other of the fabric plate 3, one end of the guide plate 23 is connected to one end of the distribution plate 31 on the corresponding fabric plate 3. When two fabric plates 3 share a single distribution plate 31, that is, when only one distribution plate 31 is provided between two fabric plates 3, a Y-shaped branch structure can be provided at the end of the distribution plate 31 to connect with the two guide plates 23. By connecting the guide plate 23 to the fabric plate 3, gaps in the material movement path can be reduced, avoiding material spillage.

[0057] In an optional embodiment, protective nets can be provided on the two sides of the main body section 21 parallel to the material movement direction and on the side of the main body section 21 away from the shrinkage section 22, so as to prevent the material from falling to the outside of the main body section 21 due to the vibration of the main body section 21 after entering the main body section 21 during operation of the segregation distributor. The protective net can include a wire mesh, a frame and a base. The wire mesh is formed by multiple flexible metal wires woven in a cross pattern and is fixedly set inside the frame. The base is fixed on the bottom edge of the frame. The base is preferably a magnetic base with a strong magnet, which can be installed on the part of the screen frame located in the main body section 21 by adsorption. In this way, in actual use, the above-mentioned protective net can be selectively installed according to the specific use situation, and the protective net can also be easily replaced.

[0058] The separation feeder provided in this embodiment has a multi-stage screen 2 whose main body section 21 can be parallel to each other, so that the material can be evenly distributed on each layer of screen 2, improving screening efficiency and screening accuracy, and is also easy to manufacture and maintain; in order to make the material outlet of each screen 2 located in the same plane, the end of the contraction section 22 away from the main body section 21 needs to be inclined towards the feed plate 3.

[0059] Alternatively, in this embodiment, the main body section 21 of different screens 2 can also be set with angles. For example, the upper screen 2 can have a larger tilt angle, and the tilt angle of each level of screen 2 can gradually decrease from top to bottom, so that the movement trajectory of the material on each layer of screens better matches the particle size classification requirements. For example, the upper coarse screen uses a larger tilt angle to speed up the material passing speed, while the lower fine screen reduces the tilt angle to extend the screening time and avoid fine particles not being fully screened.

[0060] In this embodiment, the contraction section 22 of the bottommost screen 2 can be parallel to the corresponding fabric plate 3, while the ends of the contraction sections 22 of the remaining screens 2 that are away from the main body section 21 need to be inclined towards the fabric plate 3. Alternatively, the ends of the contraction sections 22 of all screens 2 that are away from the main body section 21 can be inclined towards the fabric plate 3, thereby accelerating the movement speed of the material.

[0061] In other embodiments, the screen 2 can also be arc-shaped. The arc-shaped screen 2 can improve screening efficiency and have a larger throughput. During the assembly process, parameters such as the installation angle and curvature (radius of curvature and wrap angle) of the arc-shaped screen 2 can be designed and adjusted so that the material outlets of each screen 2 converge on the same plane.

[0062] The separation fabric feeder provided in this embodiment, such as Figure 3 As shown, it also includes a vibration damping component 11. The vibration damping component 11 is fixed around the equipment body 1 to support the equipment body 1, thereby preventing the equipment body 1 from interfering with the operation of other equipment due to vibration.

[0063] In an optional embodiment of this example, the vibration damping component 11 includes an upper support plate, a lower support plate, and multiple springs. The upper support plate is fixedly connected to the side plate of the main body 1 of the equipment, and ribs can be provided between the upper support plate and the side plate to improve the connection strength. The lower support plate is spaced apart from the upper support plate, and the springs are arranged between the upper support plate and the lower support plate. The lower support plate is connected to the ground or other support structures used to support the segregation fabric distributor.

[0064] In an optional embodiment, the aforementioned spring can be replaced with a hydraulic shock absorber, and the segregating fabric distributor also includes an energy recovery module. During use, the vibration of the main body of the equipment is transmitted to the hydraulic shock absorber, which, in conjunction with the energy recovery module, recovers and utilizes the vibration energy. Specifically, the hydraulic shock absorber incorporates a piston, cylinder, and one-way valve. High-viscosity hydraulic oil is filled between the piston and cylinder. During use, the frame body 1 drives the piston to reciprocate linearly within the cylinder, compressing the hydraulic oil and allowing it to flow between different chambers through the one-way valve, converting the mechanical energy generated by vibration into the pressure energy of the hydraulic oil. The energy recovery module includes a hydraulic motor, generator, voltage stabilizing circuit, and lithium battery pack. The hydraulic shock absorber is connected to the hydraulic motor via a high-pressure oil pipe. The hydraulic motor adopts an axial piston structure, which has high energy conversion efficiency. When high-pressure hydraulic oil flows into the hydraulic motor, it pushes the piston to rotate, converting the pressure energy of the hydraulic oil into rotational mechanical energy, driving the output shaft of the hydraulic motor to rotate. The output shaft of the hydraulic motor is connected to the input shaft of the generator. The generator is a permanent magnet synchronous generator, characterized by its small size, light weight, and high power generation efficiency. The rotational mechanical energy of the hydraulic motor is transferred to the generator, which drives the generator rotor to cut magnetic field lines, thereby generating alternating current (AC). The AC power generated by the generator is first converted into direct current (DC) by a rectifier bridge, and then regulated by a voltage regulator circuit to convert the unstable DC voltage into a stable voltage suitable for charging the lithium battery pack.

[0065] Furthermore, the aforementioned segregation feeder can also be equipped with vibration state monitoring sensors for detecting vibration parameters, displacement sensors for monitoring the displacement trajectory of the main body of the equipment, material layer thickness sensors and particle size distribution sensors for monitoring material characteristics and providing feedback on screening effects, as well as several early warning sensors for detecting the operating status of the segregation feeder. The segregation feeder can be equipped with any one or more of the above sensors. All of the above sensors can be electrically connected to the lithium battery pack of the energy recovery module, so that the lithium battery pack can power each sensor, reducing the wiring between the segregation feeder and the external power source and reducing production costs.

[0066] In other embodiments, the vibration damping component 11 described above can also be multiple vibration damping pads stacked together, which can also achieve the vibration damping purpose in this embodiment.

[0067] In an optional embodiment, the segregation fabricator further includes a dust cover; the dust cover is detachably installed on the outside of the main body 1 of the equipment; the dust cover has a discharge port and a feed port, wherein the fabric plate 3 can extend out of the dust cover through the discharge port to connect with downstream equipment; preferably, the dust cover is also provided with a negative pressure port, which is used to connect with a negative pressure dust collection system to realize the immediate removal of dust generated by the segregation fabricator during operation, improve the working environment, reduce the impact of dust on the environment and the harm of dust to the health of operators.

[0068] In an optional embodiment, an automatic roller brush cleaning device can be installed below the screen 2. The roller brush can be made of nylon and is driven by a motor to rotate, thereby cleaning the material adhering to the surface of the screen 2 and preventing the screen holes of the screen 2 from clogging. Alternatively, a jet blowing device can be installed below the screen 2. The jet blowing device consists of an air pump, an air tank, a solenoid valve, and a jet pipe. The air tank, air pump, solenoid valve, and jet pipe are connected in sequence, and the jet pipe is located below the screen 2. During use, the solenoid valve controls the compressed air in the air tank to be sprayed onto the surface of the screen 2 through the jet pipe at preset intervals, using high-pressure airflow to blow out the material clogging the screen holes. By setting different pulse frequencies and jet pressures, the cleaning needs of different materials can be adapted to achieve efficient and automated cleaning.

[0069] Another embodiment of this utility model provides an intelligent dry separation system, including the separation fabric feeder in any of the above embodiments.

[0070] The intelligent dry separation system provided in this embodiment also includes a multi-channel intelligent dry separator. The multi-channel intelligent dry separator has multiple feed inlets. The screen 2 and the feed plate 3 of the separation feeder correspond one-to-one with the intelligent dry separator. The end of the feed plate 3 away from the screen 2 is connected to the corresponding feed inlet so that the graded material can enter the corresponding processing channel.

[0071] In this embodiment, when the segregation feeder and the multi-channel intelligent dry separator work together, the segregation feeder, through the linkage of the multi-stage screen 2 and the drive source 4, and in conjunction with the feed plate 3 corresponding to the screen 2, accurately classifies the material according to particle size. This ensures a more uniform particle size distribution of the material entering the multi-channel intelligent dry separator, effectively avoiding sorting errors caused by mixed particle sizes, significantly improving sorting accuracy, increasing the recovery rate of clean coal, reducing the mis-selection rate of gangue, and ensuring the efficient utilization of coal resources. Simultaneously, under the continuous vibration of the drive source 4, each feed plate 3 achieves efficient material distribution and spreading functions, allowing the material to enter each channel of the multi-channel intelligent dry separator in a stable and uniform state, greatly improving the processing efficiency of the multi-channel intelligent dry separator, and providing a wider particle size processing capability.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
