Description

Technical Field

[0001] This utility model relates to the field of material handling equipment, and in particular to a mobile silo anti-clogging vibrating discharge port screen assembly. Background Technology

[0002] Blockage at the discharge port of a mobile silo is often caused by the material bridging effect (particles supporting each other to form a bridge), cohesion (powdered materials absorbing moisture and clumping), or adhesion (materials adhering to the inner wall of the discharge port). Vibrating discharge ports break the material bridging structure through mechanical vibration, and at the same time use vibration energy to reduce the friction between the material and the wall, thus achieving continuous unloading.

[0003] Through the synergistic optimization of the vibration system and structural design, mobile silos can reduce outlet blockage by over 90% and improve unloading efficiency by 30%-50%, making them particularly suitable for scenarios requiring frequent movement and unloading. In practical applications, customized solutions are needed based on parameters such as material bulk density, moisture content, and particle size distribution. For example, for bulk density > 1.5 t / m³... 3 For ore materials, a vibratory motor with a power of ≥1.5kW should be selected, while for lightweight powder materials (such as milk powder), an electromagnetic vibrator with a smooth inner wall design is preferred.

[0004] The mobile hopper anti-clogging vibrating discharge port has the following drawbacks: when discharging, particles of different sizes are discharged together, resulting in large particles being mixed with small particles or fine powder. This requires additional personnel to perform secondary sorting operations using other equipment, making the overall processing flow more cumbersome. To address these issues, a mobile hopper anti-clogging vibrating discharge port screen assembly is proposed. Utility Model Content

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a mobile hopper anti-clogging vibrating discharge screen assembly, including a hopper body and a feed inlet. The feed inlet is fixedly connected to the front outer wall of the hopper body. A vibrating machine frame is fixedly connected to the bottom inner wall of the hopper body.

An L-shaped frame is slidably connected to the bottom inner wall of the slide. A filter screen is fixedly connected to the front inner wall of the L-shaped frame.

[0007] As a further description of the above technical solution: the adjustment mechanism includes a T-shaped frame, which is slidably connected to the bottom inner wall of the hopper body. A pulley is fixedly connected to the bottom outer wall of the T-shaped frame, and a lever is slidably connected to the top inner wall of the T-shaped frame. A limit plate is fixedly connected to the left outer wall of the lever, and a telescopic spring is fixedly connected to the right outer wall of the lever.

[0008] As a further description of the above technical solution: an electromagnetic vibrator is fixedly connected to the inner side wall of the vibrating machine frame, and the fine material tube is connected to the inclined groove.

[0009] As a further description of the above technical solution: the filter hole penetrates the bottom outer wall of the sieve plate, an adjusting plate is slidably connected to the front inner wall of the L-shaped frame, an insert plate is fixedly connected to the bottom outer wall of the adjusting plate, and a compression spring is fixedly connected to the top outer wall of the L-shaped frame.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, through the cooperation of the vibrating machine frame and the screening mechanism, the electromagnetic vibrator drives the screen plate to vibrate. Combined with the inclined design of the chute, the material is fully dispersed and slides on the screen plate, realizing that large particles are automatically rolled into the discharge pipe for discharge, and fine particles are discharged through the filter holes and fine material pipe, which quickly completes the classification of coarse and fine particles, effectively avoids material blockage, and significantly improves material processing efficiency.

[0015] 2. In this utility model, the filter screen uses a special nanofiber membrane, which can not only intercept the dust generated during the screening process, protecting the working environment and the health of the operators, but also facilitate real-time observation of the internal filtration status due to its high light transmittance, ensuring stable operation of the screening process.

[0016] 3. In this utility model, the connection structure between the L-shaped frame and the filter screen, through the cooperation of the adjusting plate, the insert plate and the compression spring, allows the L-shaped frame to be disassembled simply by pulling the adjusting plate when replacing the filter screen, making the operation simple and quick. The installation method of the T-shaped frame and the pulley, using the lever, the limiting plate and the telescopic spring, allows the T-shaped frame and the pulley to be disassembled and replaced separately when the pulley is damaged or aged, without the need for large-scale disassembly of the entire mobile hopper, greatly shortening the maintenance time, and reducing unnecessary cost expenditures by replacing individual components, significantly reducing equipment maintenance costs and improving the practicality and economy of the equipment.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3 This utility model provides an embodiment of a mobile hopper anti-clogging vibrating discharge screen assembly, comprising a hopper body 1 and a feed inlet 2. The feed inlet 2 is fixedly connected to the front outer wall of the hopper body 1. The feed inlet 2 is located on the front outer wall of the hopper body 1 to facilitate the smooth entry of materials from the outside into the hopper body 1, providing an entry point for subsequent screening and ensuring the convenience and stability of material conveying. A vibrating machine frame 3 is fixedly connected to the bottom inner wall of the hopper body 1. A screening mechanism 4 is installed on the vibrating machine frame 3. On the frame 3, the vibration generated by the vibrating machine frame 3 can be used to screen materials, achieving coarse and fine separation of materials and improving material processing efficiency. The hopper body 1 is equipped with an adjustment mechanism 5. The screening mechanism 4 includes an inclined chute 41, which is opened on the top inner wall of the vibrating machine frame 3. Its inclined design allows the material to slide smoothly down the inclined chute 41 under the action of gravity and vibration, facilitating material flow and screening, and preventing material accumulation and blockage. The inclined chute 41 is opened on the top inner wall of the vibrating machine frame 3, and the right inner wall of the inclined chute 41 is slidably connected to a... The sieve plate 42 has filter holes 43 on its top inner wall. These filter holes 43 filter the material, allowing fine particles to pass through and separating them from larger particles, thus achieving the purpose of material screening. A discharge pipe 44 is fixedly connected to the right outer wall of the sieve plate 42. A fine material pipe 45 is fixedly connected to the bottom outer wall of the vibrating unit frame 3. A slide rail 46 is provided on the side outer wall of the hopper body 1, providing a track for the sliding of the L-shaped frame 47. It can slide stably on the main body 1 of the hopper, which facilitates the installation, disassembly and maintenance of the filter screen 48. The bottom inner wall of the slide 46 is slidably connected to an L-shaped frame 47, and the front inner wall of the L-shaped frame 47 is fixedly connected to the filter screen 48. The PET / PC transparent nanofiber membrane is made into a nanofiber network by electrospinning process. The fiber diameter is 500nm-2μm and the porosity is ≥80%. At the same time, the nanofiber has a three-dimensional porous network structure, which allows light to pass through the pores. The light transmittance is 70%-90%, and it can intercept dust particles larger than 5μm.

[0025] Reference Figures 2-4An electromagnetic vibrator is fixedly connected to the inner side wall of the vibrating machine frame 3. The electromagnetic vibrator, fixed to the inner side wall of the vibrating machine frame 3, generates vibration, causing the screen plate 42 to vibrate, thus enabling the screen plate 42 to efficiently screen the material, improving screening efficiency, and preventing material blockage on the screen plate 42. The fine material pipe 45 is connected to the inclined chute 41. The filter hole 43 penetrates the bottom outer wall of the screen plate 42. An adjusting plate 49 is slidably connected to the inner front wall of the L-shaped frame 47. An insert plate 410 is fixedly connected to the bottom outer wall of the adjusting plate 49. The L-shaped frame 47 is fixed to the bottom outer wall of the adjusting plate 49 and inserted into the bottom inner wall of the slide 46. This serves to fix the L-shaped frame 47, prevent the L-shaped frame 47 from sliding randomly during the screening process, ensure the stability of the filter screen 48, and facilitate disassembly. A compression spring 411 is fixedly connected to the top outer wall of the L-shaped frame 47. Frosted pads are fixedly connected to the top and bottom outer walls of the adjusting plate 49. The insert plate 410 penetrates the bottom inner wall of the slide 46. The end of the compression spring 411 away from the adjusting plate 49 is fixedly connected to the inner wall of one side of the L-shaped frame 47.

[0026] Reference Figures 3-4 The adjustment mechanism 5 includes a T-shaped frame 51, which is slidably connected to the bottom inner wall of the hopper body 1. A pulley 52 is fixedly connected to the bottom outer wall of the T-shaped frame 51, allowing the mobile hopper to move easily in different areas, meeting the needs of adjusting the hopper position in actual use and improving the flexibility of hopper use. A lever 53 is slidably connected to the top inner wall of the T-shaped frame 51. A limit plate 54 is fixedly connected to the left outer wall of the lever 53, and a telescopic spring 55 is fixedly connected to the right outer wall of the lever 53. Silicone pads are fixedly connected to the left and right outer walls of the lever 53. The silicone pads increase friction, making it easier for operators to move the lever 53 and making operation more convenient. At the same time, the silicone pads have a certain buffering effect, reducing wear between the lever 53 and other parts. The limit plate 54 penetrates the left inner wall of the hopper body 1, and a steel plate is fixedly connected to the side outer wall of the limit plate 54. The end of the telescopic spring 55 away from the lever 53 is fixedly connected to the right inner wall of the T-shaped frame 51.

[0027] Working principle: When material enters the main body 1 of the hopper from the feed inlet 2, it falls into the inclined chute 41. At the same time, the vibrating frame 3 vibrates, causing the screen plate 42 to vibrate. The screen plate 42 causes large particles to roll into the discharge pipe 44 along the surface slope, discharging the large particles. Simultaneously, the filter holes 43 on the surface of the screen plate 42 filter the fine particles through, allowing the fine particles to be discharged outward through the fine material pipe 45, thus quickly classifying coarse and fine particles. During the vibration filtration and screening process, dust is generated. The filter screen 48 prevents the dust from flying out and allows personnel to observe the internal structure in real time. The filtration status is monitored, and the insertion plate 410 is moved by pulling the adjustment plate 49, separating the insertion plate 410 from the main body 1 of the hopper. Then, the L-shaped frame 47 is pulled to separate from the slide 46, allowing for convenient replacement and maintenance of the filter screen 48. At the same time, the hopper needs to be moved to different areas frequently, and when the pulley 52 is damaged or aged, it needs to be stopped for a long time for maintenance. The limiting plate 54 is moved by pulling the lever 53, and the limiting plate 54 is separated from the bottom of the main body 1 of the hopper, allowing for the removal and replacement of individual T-shaped frames 51 and pulleys 52, which speeds up the replacement and maintenance efficiency and saves maintenance costs by replacing them individually.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
