Description

Technical Field

[0001] The utility model relates to a feeding device for a quartz sand production line, in particular to a feeding device for a roasting stage in a quartz sand production line. Background Art

[0002] Quartz sand is a hard, wear-resistant, chemically stable silicate mineral. Its main mineral component is silicon dioxide. The color of quartz sand is milky white or colorless and translucent. It has a hardness of seven, is brittle and has no cleavage. It has a shell-like fracture and an oily luster. Its chemical, thermal and mechanical properties have obvious anisotropy. It is insoluble in acid and slightly soluble in potassium hydroxide solution. Quartz sand is a variant of colorless and transparent quartz. Quartz sandstone is a consolidated clastic rock with a quartz debris content of more than 95%. It comes from various igneous rocks, sedimentary rocks and metamorphic rocks. There are fewer heavy minerals, and the associated minerals are feldspar, mica and clay minerals. Quartzite is divided into sedimentary and metamorphic types. The former has unclear boundaries between debris particles and cementing materials, while the latter refers to quartzite ores with deep metamorphism and pure quality. Vein quartz is formed by hydrothermal action and is almost entirely composed of quartz with a dense block structure. During the quartz sand roasting and water quenching stage, the quartz sand raw material needs to be transported to the roasting furnace. The traditional feeding method is generally to manually operate an electric hoist or use a forklift to load the material into the roasting furnace hopper. This method is inefficient and labor-intensive. The feeding method of the utility model can replace the traditional manual feeding method, and can realize automatic loading of quartz raw materials and automatic start and stop.

[0016] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] like Figure 1-4As shown, a feeding device for the roasting stage in a quartz sand production line includes a raw material bin 1, a first conveyor 3, a second conveyor 4 and a roasting furnace 2. A feeder 5 is arranged at the bottom of the raw material bin 1, and the feeder 5 conveys the quartz sand raw material to the second conveyor 4 through the first conveyor 3. A plurality of dividers 6 are arranged on the second conveyor 4, and each divider 6 is connected to a buffer bin 7 at the lower end, and the buffer bin 7 is connected to the roasting furnace 2; the divider 6 includes a two-way control cylinder 601 and a divider plate 602, and the two-way control cylinder 601 controls the closing / separation of the divider plate 602.

[0018] Preferably, the second conveyor 4 is provided with distributors 6 at intervals in sequence.

[0019] Preferably, there are several roasting furnaces 2 , and each roasting furnace is connected to a distributor 6 .

[0020] Preferably, weighing modules are provided at the four corners of the buffer silo 7 , and the collected values ​​of the weighing modules are sent to the controller, and the controller controls the bidirectional control cylinder to adjust the dividing plate 602 .

[0021] Preferably, the quartz sand raw material passes through the first distributor 6 and falls into the buffer bin 7 below. When the weight of the buffer bin 7 reaches a set value, the current distributor 6 is closed, and the next distributor is fed in turn. Example

[0022] This fully automatic feeding system is based on the preparation of quartz sand process roasting and water quenching feeding as the technical background:

[0023] During the quartz sand roasting and water quenching stage, the traditional feeding method is generally to manually control the electric hoist or use a forklift to load the material into the roasting furnace hopper. The new practical feeding method can replace the traditional manual feeding method and realize automatic loading and automatic start and stop of quartz raw materials.

[0024] The feeding system is composed of a raw material bin 1, an electromagnetic feeder 5, a first conveyor 3, a second conveyor 4, a distributor 6, a weighing module, a buffer bin 7 and a control cabinet.

[0025] The quartz raw material is loaded into the raw material bin 1 by a loader. A feeder 5 is provided at the bottom of the raw material bin 1. The feeder 5 feeds the material into the first conveyor below at a uniform speed. The first conveyor 3 conveys the quartz material to the second conveyor 4. The second conveyor 4 is provided with a plurality of distributors 6. The distributors 6 block the quartz materials on the second conveyor 4 one by one and make them fall into the roasting buffer bin 7 below. The four corners of the buffer bin 7 are provided with weighing modules. When the material falling into the buffer bin 7 reaches a certain weight, the weighing module triggers the controller to lift the distributor 6, so that the material moves to the next buffer bin 7 and enters the next buffer bin through the distributor system until the material in the buffer bin reaches the set value and enters the next buffer bin. silos, when all silos have sufficient quartz raw materials, the electromagnetic feeder, the first conveyor 3 and the second conveyor 4 stop automatically under the control of the system until the weight of a certain buffer silo is lower than the set value. The automatic feeding mechanism can then be started again to load the buffer with insufficient materials, thus forming a fully automatic feeding system for the high-purity quartz sand roasting production line. The advantage of this system is that you only need to fill the raw material silo with materials, and you can use the automatic feeding system to realize automatic material distribution and quantitative stop or start, which greatly reduces manual operation, enables uninterrupted feeding of raw materials for the production line, simplifies and automates the original cumbersome work process, saves production costs, and improves production efficiency.

[0026] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by technicians familiar with the field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
