Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of unloading devices, and in particular to an unloading device and a silica sand unloading system. Background Technology
[0002] As the mainstream process in modern glass manufacturing, float glass production is highly dependent on a stable and efficient supply of raw materials. Silica sand is the core raw material, accounting for approximately 60%. Silica sand is typically produced using a wet process and transported to the factory via road (mainly using dump trucks or flatbed trucks). The existing unloading process varies significantly depending on the type of vehicle: dump trucks can directly dump silica sand into the hopper, which is then conveyed to the silica sand storage warehouse via a bucket elevator and belt conveyor; flatbed trucks, on the other hand, require a forklift to unload the material into the hopper before it is transported to the warehouse via the same conveying equipment. This differentiated reliance on forklifts for unloading results in low overall unloading efficiency, becoming a bottleneck in the production process.
[0003] To ensure compatibility with different vehicle models and support parallel unloading, existing technology proposes a multi-compartment parallel unloading port scheme. This scheme involves two rows of parallel unloading ports (each row approximately 15 meters long, with an unloading compartment spaced approximately 3 meters apart), with a parking aisle approximately 3 meters wide in the middle. Flatbed trucks park in the aisle, and a loader pushes the material to the unloading compartments on either side; dump trucks, on the other hand, dump material onto the ground above the aisle, and then a loader pushes it to the unloading compartments on either side. While this scheme achieves initial vehicle model compatibility, it still has significant drawbacks: Unresolved efficiency bottlenecks: Regardless of the vehicle type, a secondary material pushing operation by a loader is always required, resulting in redundant steps, time-consuming and labor-intensive processes, and persistently low unloading efficiency. Uneven material distribution: During dump truck unloading, material tends to concentrate at a single point, leading to excessive localized load on the corresponding unloading bin, affecting equipment lifespan and subsequent processing. Weak design versatility: The unloading port layout is not sufficiently optimized to accommodate structural differences in different vehicle types (such as vehicle length and unloading methods), hindering improvements in unloading efficiency.
[0004] Therefore, there is an urgent need to develop a new type of unloading device to improve unloading efficiency and effectively adapt to different vehicle models, thereby ensuring the continuity, stability and overall efficiency of float glass production. Utility Model Content

As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.
[0026] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0028] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "equipped with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.
[0029] Example 1 like Figure 1-3 As shown, this embodiment provides a unloading device, including an unloading inlet 1, which is connected to an unloading bin 2 below. A supporting frame 11 is provided at the unloading inlet 1, and the supporting frame 11 is an I-beam structure. The supporting frame 11 is used to support unloading vehicles that are stationary at the unloading inlet 1 or pass through the unloading inlet 1. The unloading vehicle is used to directly unload materials into the unloading inlet 1, and the unloading bin 2 is used to receive materials falling from the unloading inlet 1.
[0030] In use, the tipper truck can be parked above the discharge inlet 1 for direct tipping and unloading, or it can move forward and unload while above the discharge inlet 1. The flatbed truck can be parked above the discharge inlet 1, and a loader can be used to unload the material from both sides of the flatbed truck into the discharge inlet 1. The discharge bin 2 is used to receive the material falling from the discharge inlet 1. This unloading device allows both flatbed and tipper trucks to unload at the same discharge inlet 1, meeting different unloading needs, effectively improving unloading efficiency, reducing equipment investment, and facilitating widespread application.
[0031] In some embodiments, the length of the unloading inlet 1 is 14m to 18m, and the width of the unloading inlet 1 is 3.6m to 5m. Controlling the length and width of the unloading inlet 1 within a reasonable range can accommodate the vehicle length and width of different unloading vehicle models, effectively improving the rationality and efficiency of the unloading operation. Preferably, the length of the unloading inlet 1 is 14m to 15m, and the width of the unloading inlet 1 is 3.6m to 4m.
[0032] In some embodiments, a grating frame is laid on the support frame 11, the grid aperture of the grating frame being smaller than that of the support frame 11. The grating frame can filter the material unloaded by the unloading vehicle. Laying a grating frame on the support frame 11 can prevent large pieces of material from clogging the system and avoid material concentration during unloading, thereby solving the problem of excessive load on local silos. In addition, it allows vehicles to pass through the unloading inlet 1 more smoothly, improving the stability of the entire unloading system. In some embodiments, the system includes at least two unloading bins 2 arranged side by side. The supporting frame 11 divides the unloading inlet 1 into at least two unloading openings 12, each corresponding to one unloading bin 2. This structural design enables more precise and orderly distribution of materials to the corresponding unloading bins 2 through different unloading openings 12, avoiding material concentration in one unloading bin 2 and thus preventing excessive load on the unloading bin 2, thereby effectively improving unloading and conveying efficiency. As a preferred embodiment of this utility model, the unloading device includes 3 to 5 unloading bins 2 arranged side by side.
[0033] In some embodiments, a discharge volume adjustment device 21 is provided at the bottom of the unloading bin 2. In some embodiments, a vibration device 22 is provided on the bin wall of the unloading bin 2.
[0034] In actual use, when the conveyed material is silica sand used to prepare float glass, the silica sand contains 5% to 8% moisture. After entering the unloading hopper 2, there are still problems such as material accumulation, poor discharge, and excessive discharge. By installing a discharge rate adjustment device 21 at the outlet end of the unloading hopper 2 and adding a vibration device to the hopper wall, the flow rate of the material can be easily controlled when the moisture content of the silica sand is stable.
[0035] More preferably, the feeding amount regulating device 21 is a bar-type regulating gate. Specifically, as shown below... Figure 3 As shown, the material discharge adjustment device 21 includes an adjustment frame 211, which has several removable rods 212. In use, the adjustment frame 211 is installed at the bottom of the discharge bin 2, and the size of the discharge outlet is adjusted by removing the number of rods 212. This operation is simple and convenient. The vibration device 22 is an eccentric vibration motor. When in use, the feeding rate can be adjusted by adjusting the number of pull-out rods 212, and the material feeding efficiency can be adjusted by adjusting the vibration amplitude of the vibration device 22.
[0036] like Figure 4 As shown, this embodiment provides a silica sand unloading system, including the unloading device described above. A material conveying system 3 is arranged below the unloading bin 2. The material conveying system 3 is used to receive the silica sand material falling from the unloading bin 2 and convey the silica sand material to the silica sand storage tank.
[0037] This utility model provides a silica sand unloading system. Silica sand is unloaded into the unloading bin 2 through the unloading inlet 1, and then transported to the storage silo by the material conveying system 3. This realizes the orderly flow of silica sand from the unloading stage to the storage stage. The system is simple to operate and easy to promote.
[0038] In some embodiments, the material conveying system 3 includes a belt conveyor and / or a bucket elevator.
[0039] In some embodiments, an online moisture monitor is installed at the bottom of the unloading hopper 2 to monitor changes in the moisture content of the incoming material.
[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
