Description

Technical Field

[0001] The utility model relates to the technical field of composite adhesive production, in particular to a feeding device for composite adhesive production. Background Art

[0002] Coal-based direct reduction in rotary hearth furnace is a new non-blast furnace ironmaking process and a typical representative process for treating zinc-containing dust and mud in steel plants. It mainly adds a certain proportion of carbon powder and binder to various zinc-containing dust and mud, mixes and presses them into carbon-containing pellets, and then goes through steps such as drying, preheating and high-temperature solid-state reduction to effectively utilize the iron, carbon and zinc oxide in the dust and mud to produce metallized pellets to return to steel production. The steam generated is returned to the production steam network, and the by-product zinc oxide powder is produced at the same time, which can be used as a secondary resource. The rotary hearth furnace process has the advantages of high impurity removal rate and good metallization degree, and has become a hot spot for steel companies. It is one of the development trends of iron-containing dust and sludge treatment technology in the industry. In the process of carbon-containing pelletizing and consolidation, a binder is needed. A suitable binder can provide sufficient bonding force for the pellets during transportation to resist the impact force during transportation, and even partially provide slag phase bonding at high temperature, thereby improving the high-temperature consolidation ability of the pellets during the reduction process. The consolidation strength of the pellets using only organic binders at high temperatures often does not meet the production requirements. Composite binders must be used to make up for the problem that the inorganic binder has weak bonding strength at room temperature and high addition amount, while the organic binder has weak bonding strength at high temperatures.

[0003] In the production process of composite binder, mainly raw materials such as bentonite, cellulose and starch are required, and the composite binder can be synthesized after stirring. Before stirring, various raw materials need to be added into the mixing bin, and the raw materials are generally added into the mixing bin through a metering feeding mechanism. However, the existing feeding mechanism is often single and fixed in structure during use, and it is difficult to make targeted adjustments according to the adding characteristics of different raw materials, so that each raw material needs to be configured with a feeding mechanism, which not only makes the versatility of the feeding mechanism poor, but also because each raw material is configured with a feeding mechanism, resulting in more structures on the feeding surface of the mixing bin, which makes the whole device more complicated.

[0004] Therefore, it is necessary to invent a feeding device for composite adhesive production to solve the above problems. Utility Model Content

[0023] The utility model provides Figure 1-Figure 5 The feeding device for composite adhesive production shown in the figure comprises a mixing bin 1 for mixing and stirring various raw materials of composite adhesive, a left feeding mechanism 2 arranged on the left side of the top of the mixing bin 1 and a right feeding mechanism 3 arranged on the right side of the top of the mixing bin 1, the top of the right feeding mechanism 3 is connected to a transfer bin 4, the top of the transfer bin 4 is provided with a feeding assembly, the peripheral side wall of the feeding assembly is plugged with a plurality of dust suction pipes 8, the dust suction direction of each dust suction pipe 8 is vertically downward, the side wall of the transfer bin 4 is connected to an inclined guide pipe 14, the inclined guide pipe 14 is rotatably provided with a spiral blade 16 for spiral feeding, the top of the left feeding mechanism 2 is detachably connected to the left side of the outer peripheral side wall of the inclined guide pipe 14, the transfer bin 4 is rotatably provided with a sealing plate 18 for closing the side or bottom of the transfer bin 4, when raw materials are added to the feeding assembly, the generated flying dust can be collected through a plurality of dust suction pipes 8 to prevent flying dust from polluting the on-site environment.

[0024] The top of the transfer bin 4 is an open end, and a bin cover 5 is detachably installed on the top of the transfer bin 4. The feeding assembly includes a feeding ring bin 6 with an open end and a guide ring bin 7 that is detachably abutted against the open end of the feed ring bin 6 and extends deep into the feed ring bin 6. The bottom end of the feed ring bin 6 is detachably connected to the top of the bin cover 5. The guide ring bin 7 can increase the feeding area of ​​the feed ring bin 6, thereby facilitating one-time large-scale feeding.

[0025] The part of the guide ring bin 7 that penetrates into the feed ring bin 6 is surrounded by the feed ring bin 6 to form an annular space, and the bottom end of the annular space is an open end. The part of the dust suction pipe 8 that is inserted into the feed ring bin 6 is located in the annular space, and the bottom end of the dust suction pipe 8 is connected to a suction head 11, and the dust suction direction of the suction head 11 is vertically downward. A dust collecting pipe 9 is commonly connected between one end of multiple dust suction pipes 8 located outside the feed ring bin 6, and a dust outlet pipe 10 is connected to the side wall of the dust collecting pipe 9. When flying dust appears, it flies upward. At this time, the vertically downward suction head 11 adsorbs and collects the dust, and finally transmits it to the dust collecting pipe 9 through the dust suction pipe 8 for temporary storage, and finally discharges it outward through the dust outlet pipe 10.

[0026] A first material discharge trough 12 is provided on the bottom surface of the transfer bin 4, and a second material discharge trough 13 is provided on one side wall of the transfer bin 4.

[0029] In the utility model, the raw materials required for the production of the composite binder are added to the transfer bin 4 through the feeding assembly. For raw materials such as bentonite and cellulose, the position of the sealing plate 18 is changed to close the side of the transfer bin 4, and then the bottom of the transfer bin 4 is opened, so that the raw materials such as bentonite and cellulose enter the mixing bin 1 through the right feeding mechanism 3. Since gelatinized starch has explosive properties, it is necessary to use spiral feeding to prevent explosion. At this time, the position of the sealing plate 18 is changed to close the bottom of the transfer bin 4, and then the side of the transfer bin 4 is opened, so that the starch raw material passes through the spiral blades 16 in the inclined guide pipe 14 to complete spiral feeding, and finally enters the mixing bin 1 through the left feeding mechanism 2. Finally, according to the addition characteristics of different raw materials, the same feeding structure is used to change different feeding channels to complete the feeding process, thereby improving the versatility of the entire device, and there is no need to configure a set of feeding mechanisms for each raw material. The feeding process for different raw materials can be completed by a set of feeding mechanisms and changing the feeding channels, which greatly simplifies the entire feeding structure.
