Abstract
Description
Technical Field
[0001] This application relates to the field of wet material spreading technology, specifically a wet material spreading device. Background Technology
[0002] Wet material spreading refers to the operation of spreading (i.e., material distribution and spreading) materials containing a certain amount of moisture. It has important applications in many industrial fields such as chemical, food, metallurgy, and building materials. Wet material spreading is a process in which a spreading device is used to evenly spread granular, powdery, or slurry materials with a certain amount of moisture on the surface of specific equipment (dryer, conveyor belt) to form a material layer with a certain thickness and uniformity, ensuring that the material is heated evenly in subsequent processing.
[0003] Some existing wet material distribution devices consist of a conveying pipe, a single auger, and a drive motor. The drive motor drives the single auger to rotate inside the conveying pipe. The rotation of the auger causes the wet material to be discharged from the outlet of the conveying pipe, spreading the wet material onto the (dryer, conveyor belt), thus completing the process of conveying and distributing the wet material. However, during the conveying process, the wet material inside the conveying pipe tends to accumulate near the outlet. Due to the lack of a return material mechanism, it is inconvenient to reverse the excess wet material near the outlet of the conveying pipe and transport it back to the inlet of the conveying pipe for recycling. The wet material accumulated near the outlet of the conveying pipe will fall unevenly, which can easily lead to problems such as uneven distribution thickness and local accumulation.
[0004] Therefore, it is necessary to provide a wet material spreading device to solve the above problems.
[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.
[0032] like Figure 1-2As shown, this application provides a wet material spreading device, including a support frame 1. The support frame 1 is the core load-bearing structure, welded from high-strength steel, possessing good rigidity and stability, and capable of withstanding various loads generated during the wet material spreading process. Four support legs 5 are symmetrically fixed to the bottom surface of the support frame 1. Adjustable anchor bolts (not shown in the figure) are designed at the bottom of each support leg 5. By adjusting the anchor bolts, the device can remain level on ground with varying flatness, ensuring the stability of the spreading process.
[0033] Multiple sets of reinforcing plates 6 are fixed to the outer wall at the lower end of the support frame 1. These reinforcing plates 6 are distributed in a triangular pattern and are welded with the columns and beams of the support frame 1 to form a stable structure, which enhances the deformation resistance of the support frame 1 and effectively resists the vibration and impact that may occur during the wet material laying process.
[0034] like Figure 4 As shown, the support frame is equipped with a lifting assembly 2. The lifting assembly 2 includes two hydraulic cylinders 21 fixedly installed inside the support frame 1. The two hydraulic cylinders 21 are symmetrically distributed. The output end of each hydraulic cylinder 21 passes through the top of the support frame 1 through a connecting flange and is fixedly installed with an mounting plate 22. The mounting plate 22 serves as the connection hub between the lifting assembly 2 and the spiral fabric assembly 3. The mounting plate 22 is made of thickened steel plate.
[0035] At the lower end of the mounting plate 22, multiple guide rods 23 are vertically fixed. The guide rods 23 slide with the pre-set guide holes (not marked in the figure) on the support frame 1. The surface of the guide rods 23 is hardened, has high hardness and smooth surface. With the guide holes, the swaying and offset of the mounting plate 22 during the lifting process can be limited, so that the mounting plate 22 can move smoothly up and down in the vertical direction, thereby realizing the adjustment of the fabric height.
[0036] like Figure 5-6 As shown, a spiral feeding assembly 3 is provided on the support frame 1. The spiral feeding assembly 3 includes a feeding pipe 31 fixedly installed on the mounting plate 22. The feeding pipe 31 is fixedly installed in the middle of the mounting plate 22 and adopts a cylindrical hollow structure design. The material is made of wear-resistant and corrosion-resistant stainless steel to adapt to the special properties of wet materials. A square feed port (not marked in the figure) is provided on one side of the upper end of the feeding pipe 31. A feed hopper 38 is fixedly installed at the feed port. The feed hopper 38 is inverted trapezoidal. Its small diameter end is connected to the feed port, and its large diameter end is used to receive materials and guide the materials smoothly into the interior of the feeding pipe 31, while reducing the blockage of materials during the feeding process.
[0037] On one side of the lower end of the conveying pipe 31, there is a rectangular material outlet (not marked in the figure). A guide plate 37 is fixedly installed on one side of the material outlet. The guide plate 37 adopts an inclined design and its width matches the material outlet. It can guide and disperse the material discharged from the material outlet, so that the material is distributed at an ideal angle and range.
[0038] A discharge auger 32 is rotatably mounted at one end inside the conveying pipe 31. A drive motor 34 is fixedly mounted on one side of the outer wall of the conveying pipe 31. The drive motor 34 is a high-torque, low-speed motor that can provide stable power output. The drive motor 34 is fixedly connected to the shaft end of the discharge auger 32 through a reducer. The reducer adopts a gear transmission structure, which has the characteristics of high transmission efficiency and low noise. It can convert the high-speed rotational motion of the drive motor 34 into the low-speed, high-torque rotational motion required by the discharge auger.
[0039] At the other end inside the conveying pipe 31, a return screw auger 33 is rotatably installed. The discharge screw auger 32 and the return screw auger 33 rotate in the same direction. One end of the discharge screw auger 32 and the return screw auger 33 both penetrate the side wall of the conveying pipe 31. A first gear 35 and a second gear 36 are fixedly installed on the shaft end outside the conveying pipe 31, respectively. The first gear 35 and the second gear 36 are meshed and connected to each other.
[0040] The power transmission and steering control between the discharge screw auger 32 and the return screw auger 33 are realized through gear transmission. Because they are driven by gear meshing, their directions are opposite. The discharge screw auger 32 conveys and discharges the material, which can spread the wet material on the mesh belt of the belt dryer. The function of the return screw auger 33 is to return the excess material in the conveying pipe 31 or the material accumulated during the spreading process to the feed port in a timely manner, so as to avoid the material from blocking the conveying pipe 31 and ensure the continuity and stability of the spreading process.
[0041] like Figure 2 As shown, a sealing cap 39 is snapped onto the upper end of the conveying pipe 31. A rubber sealing ring (not marked in the figure) is provided between the sealing cap 39 and the conveying pipe 31, which can effectively prevent material leakage and dust ingress. The snap-fit structure design makes the installation and removal of the sealing cap 39 simple and quick. The sealing cap 39 can be removed directly without the use of special tools.
[0042] A protective cover 310 is fixedly installed at one end of the conveying pipe 31. The protective cover 310 adopts a fully enclosed structure, which completely encloses the first gear 35 and the second gear 36. This can effectively prevent materials, dust and other impurities from entering the gear transmission parts, avoid gear wear and failure, and also improve the safety of equipment operation.
[0043] A PLC control panel 4 is fixedly installed on one side of the support frame 1. The control panel integrates an advanced programmable logic controller (PLC) system, which has data processing and logic control capabilities. Through the PLC control panel 4, the operator can set and monitor various parameters of the device in real time, including the lifting height of the hydraulic cylinder 21, the speed of the drive motor 34, and the material feeding time.
[0044] Working principle: Before starting the wet material feeding operation, the operator needs to set parameters such as the lifting height of the hydraulic cylinder 21, the speed of the drive motor 34, and the feeding time through the PLC control panel 4 on one side of the support frame 1, according to the height of the belt dryer mesh belt, the characteristics of the material, and the feeding requirements. After receiving the instructions, the PLC system converts them into electrical signals to provide initial control logic for the operation of the equipment.
[0045] After the equipment is started, the PLC control panel 4 first sends a start signal to the two hydraulic cylinders 21 in the lifting assembly 2. After receiving the electrical signal, the hydraulic cylinder 21 pushes the piston to move, causing the output end of the hydraulic cylinder 21 to extend. Since the two hydraulic cylinders 21 are symmetrically distributed and the output end is fixed to the mounting plate 22 through the connecting flange, the mounting plate 22 rises smoothly under the push of the hydraulic cylinder 21.
[0046] The guide rod 23 at the lower end of the mounting plate 22 slides in conjunction with the guide hole on the support frame 1. Under the combined action of the high hardness and smooth surface of the guide rod 23 after quenching treatment and the guide hole, the swaying and offset of the mounting plate 22 during the lifting process are limited, ensuring that it moves accurately along the vertical direction until the preset fabric height is reached.
[0047] At the same time, the material enters the conveying pipe 31 through the feed hopper 38. The inverted trapezoidal design of the feed hopper 38 allows the large-diameter end to quickly receive the material, while the small-diameter end is connected to the feed port, effectively guiding the material smoothly into the conveying pipe 31 and reducing blockage during the feeding process. After the material enters the conveying pipe 31, the PLC control panel 4 sends a start command to the drive motor 34.
[0048] The drive motor 34, as a high-torque, low-speed motor, outputs stable power after startup. This power is reduced in speed and increased in torque through the gear transmission structure of the reducer. The reducer converts the high-speed rotational motion of the drive motor 34 into the low-speed, high-torque rotational motion required by the discharge auger 32, driving the discharge auger 32 to rotate inside the conveying pipe 31.
[0049] Since the discharge screw auger 32 and the return screw auger 33 are respectively fixedly installed with a first gear 35 and a second gear 36 meshing with each other on the shaft end outside the conveying pipe 31, the two rotate in opposite directions through gear transmission. During the rotation of the discharge screw auger 32, the wet material is pushed out from the feeding port by the pushing action of the screw blades. The guide plate 37, which is designed with an inclination on one side of the feeding port, guides and disperses the material discharged from the feeding port according to its specific angle and width, so that the material is distributed on the mesh belt of the dryer.
[0050] If material accumulates in the conveying pipe 31 during the feeding process, the return screw auger 33 will come into play. Because it rotates in the opposite direction to the discharge screw auger 32, the return screw auger 33 can promptly push the excess or accumulated material in the conveying pipe 31 back to the feed inlet under the drive of gear transmission, so that it can re-participate in the feeding process, thereby avoiding material blockage in the conveying pipe 31 and ensuring the continuity and stability of the feeding process.
[0051] Throughout the entire fabric feeding process, the rubber sealing ring between the sealing cover 39 and the conveying pipe 31 always plays a sealing role, preventing material leakage and dust entry, ensuring a clean working environment and effective material utilization. At the same time, the protective cover 310 completely encloses the first gear 35 and the second gear 36, preventing materials, dust and other impurities from entering the gear transmission parts, ensuring the normal operation of the gears, and improving the safety and reliability of equipment operation.
[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
