Description

Technical Field

[0001] The present invention belongs to the technical field of water-stable material mixing, and particularly relates to an environmental protection type feeding subsystem and a feeding system in a factory area. Background Art

[0002] A water-stable mixing station is a large-scale machine used in industrial construction to specifically mix water-stable materials. Water-stable materials generally include cement, fly ash, graded crushed stone, stabilized soil layer materials, etc. It is used for the construction of the base stabilized soil of high-grade highways, urban roads, squares, and airports. It can continuously mix and produce finished materials of different gradations of lime-fly ash gravel, lime stabilized soil, and industrial waste stabilized soil. During the mixing process in the water-stable mixing station, stable, sufficient, and corresponding materials of mixing raw materials need to be provided to the water-stable mixing station.

[0003] Traditional water-stable mixing stations often have at least two mixing stations, so two corresponding feeding systems are required to supply raw materials to the water-stable mixing station. Considering the limited site, the materials are often scattered in the raw material storage areas corresponding to the two feeding systems. In the actual use process, if the raw materials in the raw material storage area of the feeding system corresponding to a water-stable mixing station are insufficient to supply after working for a certain period of time, a transfer vehicle and a forklift will be used to transfer the raw materials in another raw material storage area to the feeding system lacking materials. Due to the installation restrictions of site equipment, the transfer vehicle and the forklift often have to travel a relatively long distance to achieve raw material transfer, which will invisibly increase the production cost and the transfer efficiency is low, making it difficult to meet the production requirements.

[0028] Embodiment 1

[0029] An environmentally friendly feeding subsystem for a factory area. Each feeding subsystem includes a first feeding unit 1 and a second feeding unit 2.

[0030] The first feeding unit 1 includes a first material bin 11 and a first conveying assembly 12. The first conveying assembly 12 is located below the first material bin 11. The raw materials in the first material bin 11 can directly fall onto the first conveying assembly 12 through the first material bin outlet 111, and are conveyed to the water-stable material mixing station by the first conveying assembly 12.

[0031] The second feeding unit 2 includes a second material bin 21 and a second conveying assembly 22. The second conveying assembly 22 is located below the second material bin 21, and the outlet of the second conveying assembly 22 is connected to another set of water-stable material mixing stations.

[0032] It further includes a feeding switching assembly 3. The feeding switching assembly 3 has a first switching conveying assembly 31 and a conveying switching assembly 33. The conveying switching assembly 33 selectively connects the second material bin outlet 211 to either the inlet 311 of the first switching conveying assembly or the inlet of the second conveying assembly 22. The outlet 312 of the first switching conveying assembly is connected to the inlet 11 of the first material bin.

[0033] Specifically, in this embodiment, the conveying and switching component 33 includes a second feeding and switching conveying component 32, a third feeding and switching conveying component 331, and a horizontal reciprocating linear motion mechanism 332. The second feeding and switching conveying component 32 is located below the outlet 211 of the second bin. The inlet of the second conveying component 22 is located below the outlet 321 of the second feeding and switching conveying component. The third feeding and switching conveying component 331 is located between the second feeding and switching conveying component 32 and the second conveying component 22. The third feeding and switching conveying component 331 is fixedly arranged at the output end of the horizontal reciprocating linear motion mechanism 332. By the movement of the output end of the horizontal reciprocating linear motion mechanism 332, the third feeding and switching conveying component 331 is switched between below the outlet 321 of the second feeding and switching conveying component and away from the outlet 321 of the second feeding and switching conveying component. When the third feeding and switching conveying component 331 is switched to below the outlet 321 of the second feeding and switching conveying component, the inlet 311 of the first feeding and switching conveying component is exactly located below the outlet 3311 of the third feeding and switching conveying component. The inlet 3312 of the third feeding and switching conveying component is located below the outlet 321 of the second feeding and switching conveying component. In this way, the raw materials falling from the outlet 211 of the second bin fall to the inlet 322 of the second feeding and switching conveying component and are transferred to the outlet 321 of the second feeding and switching conveying component by the second feeding and switching conveying component. At this time, if the third feeding and switching conveying component 331 is located at a position away from the outlet 321 of the second feeding and switching conveying component, the raw materials reaching the outlet 321 of the second feeding and switching conveying component will directly fall to the second conveying component 22 and be conveyed to the water-stable material mixing plant by the movement of the second conveying component 22. If the third feeding and switching conveying component 331 is located at a position below the outlet 321 of the second feeding and switching conveying component, the raw materials reaching the outlet 321 of the second feeding and switching conveying component will fall onto the inlet 322 of the third feeding and switching conveying component, and then be driven by the third feeding and switching conveying component to move to the outlet 3311 of the third feeding and switching conveying component, and then fall to the inlet 311 of the first feeding and switching conveying component. Driven by the first feeding and switching conveying component, the raw materials are conveyed to the outlet 312 of the first feeding and switching conveying component and then fall into the first bin 11.

[0034] The horizontal reciprocating linear motion mechanism 332 includes a slide rail 3321 and a driving mechanism 3322. The third feeding and switching conveying assembly 331 is located above the slide rail 3321. The driving mechanism 3322 applies a tendency force to the third feeding and switching conveying assembly 331, and this tendency force forces the third feeding and switching conveying assembly 331 to slide along the slide rail 3321. Preferably, the driving mechanism 3322 is a cylinder symmetrically arranged on both sides of the slide rail 3321. The piston rod of the cylinder is fixedly connected to the frame of the third feeding and switching conveying assembly 331. By introducing compressed air into the cylinder and switching the communication state of the air inlet through a reversing valve, the cylinder can drive the third feeding and switching conveying assembly 331 to move horizontally in a reciprocating manner, thereby realizing position switching.

[0035] Further preferably, since the length of the first switching conveying assembly is relatively long, and during the process of state switching, the raw materials on the first switching conveying assembly are not completely conveyed into the first bin. In this embodiment, it is preferred that after the conveying switching assembly switches from the state of connecting the outlet of the second bin to the inlet of the first switching conveying assembly to the state of connecting the outlet of the second bin to the inlet of the second conveying assembly, the first switching conveying assembly stops after a set delay. The set delay can be calculated according to the length of the first switching conveying assembly and its running speed.

[0036] Further, in this embodiment, first dust prevention devices 4 are respectively arranged at the upper openings of the first bin 11 and the second bin 21. The dust prevention device 4 includes a first dust-proof cover 41. The first switching conveying assembly 3 is covered with a second dust prevention device 5. The second dust prevention device includes a second dust-proof cover 51. The first dust-proof cover 41 and the second dust-proof cover 51 are communicated with a dust removal device (not shown in the figure) through a connecting pipe 42 / 52.

[0037] Further preferably, a first spraying device 43 and a dust concentration detector 44 are arranged in the first dust-proof cover 41. When the dust concentration detector 44 detects that the dust concentration in the first dust-proof cover 41 is too high, the dust concentration detector 44 gives an electrical signal to the controller, so that the controller controls the opening of the first spraying device 43. Of course, the first spraying device 43 can also be kept spraying continuously for dust reduction. It should be noted that the automatic control realized by the dust concentration detector belongs to the prior art. This application only uses this prior art to realize the opening of the first spraying device 43. In addition, in this embodiment, it is preferred that a second spraying device 45 is arranged on the side of the first conveying assembly 12 and the second conveying assembly 22. During the operation of the entire feeding system, the second spraying device 45 continuously sprays water mist to reduce the dust generated by the first conveying assembly 12 and the second conveying assembly 22, thereby greatly reducing the dust pollution generated during the feeding process.

[0038] Preferably, the second dust cover 51 is a cover body with a semi-circular structure, and two edges of the cover body with a semi-circular structure are fixed on the frame of the first switching and conveying assembly 3.

[0039] Embodiment 2

[0040] An environmental protection type mixing and feeding system for a factory area includes a plurality of environmental protection type mixing and feeding subsystems for the factory area. The environmental protection type mixing and feeding subsystems for the factory area are connected in series in sequence. Thus, it can be realized that each feeding subsystem corresponds to one kind of raw material, or several feeding subsystems correspond to one kind of raw material, so as to realize the feeding of multiple raw materials and the transfer of raw materials between two feeding systems.

[0041] The first conveying assemblies 12 of the first feeding unit 1 are connected in series in sequence, the second conveying assemblies 22 of the second feeding unit 2 are connected in series in sequence, and the first conveying assemblies 12 and the second conveying assemblies 22 are arranged in parallel, so as to realize the weight ratio matching of different raw materials during the conveying process, which is beneficial to the precise mixing ratio of the water stable material mixing station.

[0042] The above embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention shall be covered within the protection scope of the present invention.
