Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and more specifically, to a sealed conveyor that prevents material spillage. Background Technology

[0002] In industrial production processes, conveyors are widely used for transporting materials.

[0003] Traditional conveyors often spill materials when transporting powdery or granular materials, resulting in waste, environmental pollution, and increased cleaning costs. Furthermore, existing conveyors often have poor sealing, failing to meet the requirements for sealed transport of materials with special environmental requirements or those prone to airborne particles, leading to leakage and impacting production safety and product quality.

[0004] Therefore, it is necessary to provide a sealed conveyor that prevents material spillage to solve the above-mentioned technical problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a sealed conveyor that prevents material spillage, thus solving the problems mentioned in the background section.

[0007] (II) Technical Solution

[0008] The specific technical solution adopted in this utility model is as follows:

[0009] A sealed conveyor for preventing material spillage includes a sealed conveyor box. A housing and support legs are located at the bottom of the sealed conveyor box. Conveyor rollers are movably installed inside the sealed conveyor box, and a conveyor belt is positioned between two of the conveyor rollers. One of the conveyor rollers is driven by a drive motor. An electric push rod is installed on the outer surface of the sealed conveyor box. An anti-spillage component is installed through the output end of the electric push rod, penetrating the surface of the sealed conveyor box. A limit plate is installed inside the anti-spillage component, with its surface abutting against the end face of the conveyor belt. A support plate is installed on the bottom surface of the limit plate, with its top surface contacting the bottom surface of the conveyor belt. An adjusting rod is installed on the side of the support plate. By installing the anti-spillage component driven by the electric push rod on the outside of the sealed conveyor box, ensuring the limit plate abuts against the end face of the conveyor belt and the support plate contacts the bottom surface of the conveyor belt, and in conjunction with the adjusting rod on the side, a multi-layered protection system is constructed. During material conveying, the limiting plate acts as a sturdy barrier, effectively preventing material from overflowing to both sides and avoiding spillage. The support plate provides stable support for the conveyor belt, preventing it from sinking or deforming due to material weight and reducing the risk of spillage. The adjusting rod can flexibly adjust the position and pressure of the anti-spill components according to the actual conditions such as material particle size, flow rate, and conveying speed, ensuring the anti-spill effect while enabling the conveyor to adapt to the conveying needs of various materials. Simultaneously, the sealed conveyor box encloses the entire conveying space, preventing the leakage of easily airborne materials such as powders and granules. This not only ensures production safety and avoids safety hazards such as dust explosions, but also prevents materials from contacting the external environment, ensuring product quality, reducing product losses due to material contamination, and lowering production costs.

[0010] Preferably, a material drop plate is movably installed inside the sealed conveyor box below the conveyor rollers. A horizontal plate is provided on the surface of the support leg, and an electric push rod is installed on the horizontal plate. An extrusion head is provided at the output end of the electric push rod, and the extrusion head contacts the bottom surface of the material drop plate. The material drop plate located below the conveyor rollers inside the sealed conveyor box, along with the electric push rod and extrusion head mounted on the horizontal plate of the support leg, forms an efficient material spillage handling mechanism. When material accidentally falls from the conveyor belt onto the material drop plate, the electric push rod, under the command of the controller, drives the extrusion head to move upward, precisely lifting the material drop plate and changing its discharge angle. This design allows spilled material to slide quickly and smoothly to a specific collection area under gravity, preventing material from accumulating randomly inside the conveyor box. Compared to traditional manual cleaning methods, this greatly improves material collection efficiency, reduces labor intensity, effectively prevents secondary spillage, further reduces material waste, keeps the inside of the conveyor clean, ensures stable and reliable operation of the conveyor, and extends the service life of the equipment.

[0011] Preferably, multiple adjusting rods are provided, and these rods are installed at equal intervals on the sides of the support plates, with the adjusting rods on the sides of the two support plates staggered. This staggered arrangement of multiple equally spaced adjusting rods significantly enhances the flexibility and stability of the anti-spill assembly adjustment. In practical applications, different materials exhibit varying distribution patterns and motion characteristics on the conveyor belt. The staggered adjusting rods can apply force to the anti-spill assembly from multiple directions, resulting in a more uniform pressure distribution between the anti-spill assembly and the conveyor belt. This not only improves the stability of the anti-spill effect, ensuring effective material prevention under various operating conditions, but also enhances the structural strength and durability of the anti-spill assembly, reduces component damage caused by uneven local stress, lowers equipment maintenance costs, and improves the overall performance of the equipment.

[0012] Preferably, a feeding hopper is installed on the top surface of the sealed conveyor box. This feeding hopper features a reasonable inclination angle and diameter design, facilitating the rapid and smooth pouring of materials into the conveyor, reducing the time and difficulty of manual loading, and improving the efficiency of material conveying. Simultaneously, the feeding hopper and the sealed conveyor box are connected in a sealed manner, ensuring that no dust will fly or material will leak during the material pouring process. This further guarantees the sealing and environmental friendliness of the material conveying process, maintains air quality in the production workshop, and protects the health of operators.

[0013] Preferably, the top surface of the sealed conveyor box is provided with an inspection port, which is fitted with an inspection door. The inspection port and the fitted inspection door on the top of the sealed conveyor box greatly facilitate the daily inspection, maintenance, and troubleshooting of the conveyor. During equipment operation, if faults such as conveyor belt wear, conveyor roller jamming, or loose parts occur, personnel do not need to disassemble a large number of parts; they can simply open the inspection door to quickly enter the conveyor box for inspection and repair. This not only shortens equipment downtime and reduces production interruption losses caused by equipment failure, but also reduces the workload of maintenance personnel, improves the convenience and efficiency of equipment maintenance, helps extend the service life of the equipment, and ensures the continuity of production.

[0014] Preferably, the bottom surfaces of the chassis and support legs are equipped with pulleys, and multiple pulleys are provided. These multiple pulleys give the conveyor excellent mobility. In industrial production scenarios, operators can easily push the conveyor to a designated location according to the needs of production layout adjustments, equipment maintenance, or switching between different production lines. The pulley design reduces friction during equipment movement, lowers the difficulty of manual pushing, and ensures the stability of the equipment during movement, preventing damage due to difficulty in movement or shaking. This flexible mobility allows the conveyor to better adapt to diverse production needs, improving equipment flexibility and the space utilization rate of the production site.

[0015] Preferably, a controller is installed on the outer surface of the motor conveyor box. This controller, mounted on the outer surface of the sealed conveyor box, acts as the "intelligent brain" of the conveyor, enabling precise control and coordinated management of various components such as the drive motor, electric push rods, and electric top rods. Through preset programs and real-time data feedback from sensors, the controller can precisely adjust the operating parameters of each component according to the actual needs of material conveying. For example, it can control the speed of the drive motor to adjust the material conveying speed, control the extension and retraction distance of the electric push rods to optimize the position of the anti-spill components, and control the lifting angle of the electric top rods to achieve a reasonable tilt of the discharge plate. Simultaneously, the controller also has fault monitoring and alarm functions. Once an abnormal operation is detected, it can promptly issue an alarm and take corresponding protective measures to ensure the safety of equipment and personnel, and improve the intelligence level and operational reliability of the equipment.

[0016] Compared with related technologies, the sealed conveyor for preventing material spillage provided by this utility model has the following beneficial effects:

[0017] (1) This utility model, by setting an anti-spillage component driven by an electric push rod on the outside of the sealed conveyor box, wherein the limiting plate abuts against the end face of the conveyor belt, and the support plate contacts the bottom surface of the conveyor belt, and in conjunction with the adjusting rod on the side, can effectively limit the spillage of materials during the conveying process. When the material is conveyed on the conveyor belt, the limiting plate can prevent the material from overflowing to both sides, while the support plate provides stable support for the conveyor belt, preventing the conveyor belt from sinking due to material accumulation and causing spillage. The adjusting rod can adjust the position and pressure of the anti-spillage component according to the actual material conveying situation, ensuring the anti-spillage effect while adapting to the conveying of materials of different thicknesses and flow rates, greatly reducing material waste, lowering cleaning costs, and improving the adaptability of the conveyor to various materials. At the same time, the design of the sealed conveyor box realizes the sealed conveying of easily airborne materials such as powder and granules, meeting the conveying needs of materials with special environmental requirements or easily airborne materials, ensuring production safety and product quality, and avoiding material leakage from causing pollution to the working environment.

[0018] (2) This utility model features a material drop plate installed below the conveyor rollers inside the sealed conveyor box. Through the cooperation of an electric push rod and an extrusion head mounted on the horizontal plate of the support legs, it achieves efficient collection and processing of spilled materials. When material falls from the conveyor belt onto the material drop plate, the electric push rod precisely drives the extrusion head upwards, lifting the material drop plate and changing its discharge angle. By adjusting the tilt angle of the material drop plate, the spilled material can slide quickly and smoothly to a specific collection area under gravity. This design greatly improves the efficiency of material collection, prevents spilled material from accumulating randomly inside the conveyor box, and reduces the complexity and labor intensity of manual cleaning. Simultaneously, the standardized material collection path effectively prevents secondary spillage, further reducing material waste, ensuring the cleanliness of the conveyor's interior, and guaranteeing the stable and reliable operation of the conveyor.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] Example 1

[0033] refer to Figure 1-5 The sealed conveyor box 1 serves as the main frame of the entire conveyor. Its bottom end is fixedly mounted with a housing 15 and support legs 7 via welding. The housing 15 houses core power components such as the drive motor 10, while the support legs 7 provide stable support for the equipment. Bearing seats are pre-installed on both sides of the inner side walls of the sealed conveyor box 1. The conveyor rollers 14 are movably mounted by engaging with the bearing seats at both ends, ensuring flexible rotation of the conveyor rollers 14. A conveyor belt 13 is fitted between the two conveyor rollers 14, forming a material conveying channel.

[0034] The drive motor 10 is installed inside the housing 15, and its output shaft is rigidly connected to the shaft end of one of the conveyor rollers 14 via a coupling. When the drive motor 10 is powered on, it can stably transmit power to the conveyor roller 14, driving the conveyor belt 13 to run. The electric push rod 3 is fixedly installed on the outer surface of the sealed conveyor box 1 by bolts. Its output end passes through a pre-drilled through hole on the surface of the sealed conveyor box 1, and a sealing sleeve is installed at the through hole to ensure the equipment's sealing performance. The output end of the electric push rod 3 is connected to the anti-spill assembly 12 via a flange, enabling stable power transmission.

[0035] The limiting plate 17 inside the anti-spill assembly 12 is vertically fixed to the output end of the electric push rod 3. The surface of the limiting plate 17 is in close contact with the end face of the conveyor belt 13, thus preventing material leakage. A support plate 18 is welded to the bottom end of the limiting plate 17, and the top surface of the support plate 18 contacts the bottom surface of the conveyor belt 13, providing support for the conveyor belt 13. Multiple adjusting rod 16 mounting seats are welded to the side of the support plate 18. The adjusting rods 16 are installed on the mounting seats through threaded engagement. By rotating the adjusting rods 16, the position and pressure of the anti-spill assembly 12 can be finely adjusted to adapt to different working conditions. Through the above connection and cooperation, the various components construct a complete material conveying and anti-spill system, achieving efficient, sealed, and spill-proof material conveying.

[0036] Example 2

[0037] refer to Figure 1-5 Inside the sealed conveyor box 1, hinge seats are provided on both side walls below the conveyor roller 14. The discharge plate 4 is hinged to the hinge seats via a rotating shaft, enabling movable installation and allowing the discharge plate 4 to rotate around the rotating shaft to change the discharge angle. A horizontal plate 5 is welded to the surface of the support leg 7. An electric push rod 6 is fixedly installed on the horizontal plate 5 by bolts. The output end of the electric push rod 6 is connected to the extrusion head via a ball joint. The ball joint connection allows the extrusion head to swing freely within a certain range, ensuring that it can always maintain good contact with the bottom surface of the discharge plate 4.

[0038] When material falls onto the discharge plate 4, the electric push rod 6, upon receiving a command from the controller 9, is activated. Its output shaft extends and pushes the discharge plate 4 upward through the extrusion head. Because the discharge plate 4 is hinged, it rotates and tilts around its axis under the action of the extrusion head, causing the spilled material to slide down into a designated collection area under gravity. This connection method and structural combination achieves automatic and efficient handling of spilled material, ensuring the cleanliness and stable operation of the conveyor.

[0039] Example 3

[0040] See Figure 1-5 During installation, the adjusting rods 16 are first drilled and tapped in an equidistant, staggered pattern on the side of the support plate 18 to create mounting holes for the adjusting rods 16. The adjusting rods 16 are screw-type structures with external threads at one end. They are screwed into the mounting holes and secured through the threaded connection. Multiple adjusting rods 16 apply force to the anti-spill assembly 12 from different directions. When the position or pressure of the anti-spill assembly 12 needs adjustment, precise fine-tuning of the anti-spill assembly 12 can be achieved by synchronously or asynchronously rotating the adjusting rods 16 at different positions. This ensures optimal contact between the limiting plate 17 and the end face of the conveyor belt 13, and between the support plate 18 and the bottom surface of the conveyor belt 13, thereby enhancing the stability and reliability of the anti-spill effect.

[0041] Example 4

[0042] refer to Figure 1-5 The top surface of the sealed conveyor box 1 has pre-drilled mounting holes that match the shape of the feed hopper 11. The feed hopper 11 is installed at the mounting holes via flange connections, with sealing gaskets placed between the flanges to ensure the sealing of the connection. The feed hopper 11 has a funnel-shaped structure that is wider at the top and narrower at the bottom. Its tilt angle has been optimized to allow the material to slide quickly and smoothly into the sealed conveyor box 1 using its own weight, reducing manual intervention, improving feeding efficiency, and ensuring the sealing of the material conveying process.

[0043] Example 5

[0044] refer to Figure 1-5 An inspection port is cut into the top surface of the sealed conveyor box 1, and an angle steel ring is welded around the edge of the inspection port to form an installation frame. The inspection door 2 is made of the same material as the sealed conveyor box 1. One side is hinged to the inspection port frame, and the other side is fitted with a locking device. When inspection or maintenance of the conveyor's interior is required, the locking device is opened, allowing the inspection door 2 to rotate around the hinge and open, facilitating personnel entry into the box. After closing the inspection door 2 and locking it, the inspection door 2 fits tightly against the inspection port frame, ensuring the equipment's sealing and safety.

[0045] Example 6

[0046] refer to Figure 1-5 The bottom of the chassis 15 and support legs 7 are pre-welded with pulley 8 mounting bases. The pulleys 8 are hinged to the mounting bases via axles, ensuring that the pulleys 8 can rotate freely. Each mounting base corresponds to one pulley 8, and multiple pulleys 8 are evenly distributed at the bottom of the chassis 15 and support legs 7, forming a stable mobile support structure. When the conveyor needs to be moved, the operator pushes the equipment, and the pulleys 8 roll on the ground, reducing friction and facilitating the transfer of the equipment between different work sites to meet diverse production needs.

[0047] Example 7

[0048] refer to Figure 1-4 The controller 9 is bolted to a suitable location on the outer surface of the sealed conveyor box 1 for easy observation and operation by the operator. The controller 9 is connected to components such as the drive motor 10, electric push rod 3, and electric top rod 6 via wires. The wires pass through sealed wiring holes into the interior of the sealed conveyor box 1 and the housing 15. The controller 9 has a built-in control chip and signal processing module, which precisely controls each component based on preset programs and signals from sensor feedback. For example, it receives signals from the speed sensor to adjust the speed of the drive motor 10, receives signals from the pressure sensor to control the extension and retraction distance of the electric push rod 3, and receives signals from the angle sensor to adjust the lifting angle of the electric top rod 6, enabling coordinated operation of all components and ensuring stable operation of the conveyor.

[0049] The control circuit of controller 9 can be implemented by simple programming by those skilled in the art. It is common knowledge in the field. It is only used and not modified. Therefore, the control method and circuit connection will not be described in detail.

[0050] The working principle of the raw material preheating device based on waste heat in oil refining provided by this utility model is as follows:

[0051] When the anti-spillage sealed conveyor is working, the material is first poured into the conveyor through the feed hopper 11 at the top of the sealed conveyor box 1. The drive motor 10 starts, driving one of the conveyor rollers 14 to rotate, which in turn drives the other conveyor roller 14 to rotate synchronously through the conveyor belt 13, realizing the conveying of the material on the conveyor belt 13.

[0052] During material conveying, the electric push rod 3 is in operation, pushing the anti-spill assembly 12 to ensure that the limiting plate 17 is in close contact with the end face of the conveyor belt 13, and the support plate 18 is in contact with the bottom surface of the conveyor belt 13. The limiting plate 17 effectively prevents material from overflowing to both sides of the conveyor belt 13, and the support plate 18 provides stable support for the conveyor belt 13, ensuring smooth operation of the conveyor belt 13 and preventing material spillage due to material accumulation or belt 13 swaying. The adjusting rod 16 can be adjusted according to the actual material conditions to adapt to the conveying of materials of different thicknesses and flow rates, ensuring the anti-spill effect.

[0053] When material accidentally falls from conveyor belt 13 onto the discharge plate 4, a sensor installed near the discharge plate 4 (or detected at preset time intervals according to the control logic of the electric push rod 6) detects a change in the weight or position of the material on the discharge plate 4 and transmits a signal to the controller 9. Upon receiving the signal, the controller 9 activates the electric push rod 6, whose output pushes the extrusion head upwards, precisely lifting the discharge plate 4 and tilting it to a set angle. At this point, the spilled material, under the influence of gravity, slides quickly and smoothly along the tilted discharge plate 4 to a specific collection area for subsequent unified processing. The tilt angle can be flexibly adjusted by the controller 9 using the electric push rod 6 according to the material characteristics and collection requirements.

[0054] Furthermore, the inspection port on the top of the sealed conveyor box 1 allows for convenient access to the interior of the conveyor box when inspection or maintenance is required, simply by opening the inspection door 2. The pulleys 8 at the bottom of the chassis 15 and support legs 7 facilitate the movement and position adjustment of the conveyor, meeting the needs of different working scenarios. The controller 9, installed on the outer surface of the sealed conveyor box 1, coordinates and controls all components of the entire conveyor, ensuring that all components work together and guaranteeing the stable, efficient, and safe operation of the conveyor.

[0055] Compared with related technologies, the raw material preheating device based on waste heat in oil refining provided by this utility model has the following beneficial effects:

[0056] An anti-spillage assembly 12, driven by an electric push rod 3, is installed on the outside of the sealed conveyor box 1. The limiting plate 17 abuts against the end face of the conveyor belt 13, and the support plate 18 contacts the bottom surface of the conveyor belt 13. Combined with the adjusting rod 16 on the side, this effectively limits material spillage during conveying. When material is conveyed on the conveyor belt 13, the limiting plate 17 prevents material from overflowing to both sides, while the support plate 18 provides stable support for the conveyor belt 13, preventing it from sinking due to material accumulation and causing spillage. The adjusting rod 16 can adjust the position and pressure of the anti-spillage assembly 12 according to the actual material conveying conditions, ensuring the anti-spillage effect while adapting to the conveying of materials of different thicknesses and flow rates. This greatly reduces material waste, lowers cleaning costs, and improves the conveyor's adaptability to various materials. Meanwhile, the sealed conveyor box 1 is designed to achieve sealed conveying of easily airborne materials such as powders and granules, meeting the conveying needs of materials with special environmental requirements or those prone to airborne movement. This ensures production safety and product quality, and prevents material leakage from polluting the working environment. A drop plate 4 is installed below the conveyor roller 14 inside the sealed conveyor box 1. Through the cooperation of an electric push rod 6 and an extrusion head mounted on the horizontal plate 5 of the support leg 7, efficient collection and processing of spilled materials can be achieved. When material falls from the conveyor belt 13 onto the drop plate 4, the electric push rod 6 precisely drives the extrusion head upwards, lifting the drop plate 4 and changing its discharge angle. By adjusting the tilt angle of the drop plate 4, the spilled material can slide quickly and smoothly to a specific collection area under the action of gravity. This design greatly improves the efficiency of material collection, prevents spilled material from accumulating randomly inside the conveyor box, and reduces the complexity and labor intensity of manual cleaning. Meanwhile, the standardized material collection path effectively prevents secondary spillage, further reduces material waste, ensures the cleanliness of the conveyor interior, and guarantees the stable and reliable operation of the conveyor.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
