Description

Technical Field

[0001] The utility model belongs to the technical field of material conveying, in particular to an automatic clinker boosting system for a cooler. Background Art

[0002] Aluminum ash is the product of aluminum extraction from slag produced in the production process of electrolytic aluminum casting and alloying. We also call it secondary aluminum ash. Its main components are single element aluminum, aluminum oxide, silicon dioxide, calcium oxide, iron oxide, sodium fluoride, sodium chloride, etc. It contains fluoride and is reactive and toxic.

[0003] In most of the current aluminum ash disposal or resource utilization technologies, the cooling kiln is the key cooling equipment in our current process. Due to the changes in materials, the cooling and transportation of the finished sintered materials have become difficult.

[0004] like Figure 1 As shown, in the prior art, the initial aluminum ash sintering cooling kiln uses a 30° angle between the material discharge port and the slope of the cooling kiln. The material falls to point A and naturally falls to point B through the slope. After the material falls to the cooling kiln, it is transported to the next process. The key to the problem at this stage is that the material falls naturally from point A to point B. If the material ratio and temperature control change, it will affect the poor transportation of the material. At this time, it is easy to cause the material to accumulate at point A, which will cause blockage at the cooling kiln head over time. If the material is not discharged smoothly, the air intake of the rotary kiln will be reduced, thereby causing the entire kiln condition to deteriorate. The early solution is to set an observation hole. When blockage occurs, the material can only be poked manually through the observation hole with a rake, which poses a major safety hazard.

[0005] The temperature of the material sintered in the rotary kiln is 800-950℃ (high temperature). The rake used for manual poking is made of ordinary carbon steel QB235, which is prone to deformation and bending during use. Workers must wear protective clothing, high-temperature masks, high-temperature gloves, etc. when performing the poking operation. The operation is particularly inconvenient and the safety risk is too high.

[0006] The general improvement is to change the angle between the discharge port and the cooling kiln slope from 30° to 45°, or to add a 20mm thick stainless steel plate on the slope. Increasing the slope angle will speed up the natural sliding of materials, which can indeed alleviate the problem of material accumulation. There is no big problem with the rotary kiln feed rate of 5m3 / h, but as the rotary kiln feed rate increases to 6-7m3, material accumulation and blockage problems reappear, and ultimately manual poking of materials is required, and the problem is still not solved.

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.

[0030] Example

[0031] like Figure 1 As shown, in the prior art, a slope surface 3 is provided at the bottom end of the feed port 11 , and a steel plate 31 is provided on the slope surface 3 .

[0032] like Figure 2-6 As shown, the utility model designs an automatic clinker boosting system for a cooler, comprising a cooling kiln 1, a feed port 11 is arranged on one side of the cooling kiln 1, a slope surface 3 is arranged at the bottom of the feed port 11, a bottom plate 4 for receiving falling materials is arranged on the slope surface 3, a plurality of soot blowing holes 41 are arranged alternately on the bottom plate 4; a plurality of pulse air ducts are respectively connected to the bottom ends of the soot blowing holes 41; the upper part of the bottom plate 4 is hinged on the inner wall of the feed port 11, a plurality of springs 7 are arranged on the bottom side of the slope surface 3, and the upper end of the spring 7 is arranged close to the bottom end surface of the bottom plate 4.

[0033] In actual use, the pneumatic automatic boosting system, under the premise that the material falls by its own weight, adopts the introduction of high-pressure compressed air and blowing through the soot blowing hole 41 to avoid the accumulation of materials; and the compressed air is used for purging, and the material can be cooled at the same time, thereby playing a role in cooling the material and reducing the energy consumption of the cooling kiln 1. By hinged bottom plate 4 and supported by spring 7, when the material falls, it drives the bottom plate 4 to vibrate and discharge the material continuously, and cooperates with compressed air purging, which has a dual effect, thereby solving the technical problem of material accumulation. This kind of material dropping structure successfully avoids the manual opening of the observation hole (manhole door), does not need to be manually poked, successfully avoids major safety hazards, and does not need high temperature resistant poking tools, the cost investment of special protective labor protection supplies, and saves production costs.

[0034] like Figure 4 As shown, further, the automatic clinker boosting system of the cooler of the utility model includes a compressed air tank 5, and the compressed air is connected to a plurality of main pipes 51 through a plurality of interfaces, and a plurality of branch pipes 53 are connected to the end of each main pipe 51, and a plurality of air outlet interfaces are provided on each branch pipe 53, and are connected to the soot blowing hole 41 through the air outlet interfaces.

[0035] Furthermore, each main pipe 51 is provided with a solenoid valve 52, and the solenoid valves 52 are respectively electrically connected to the PLC controller 6. Thus, the corresponding solenoid valves 52 can be controlled to be turned on and off by programming to achieve the blowing operation of the soot blowing holes 41 at the corresponding positions.

[0036] like Figure 4 As shown, as a preferred configuration of the utility model, the arrangement of the air duct is as follows:

[0037] There are five main pipes 51, each main pipe 51 is connected to two branch pipes 53, the first main pipe 51 is connected to two branch pipes 1 531, the second main pipe 51 is connected to two branch pipes 2 532, the third main pipe 51 is connected to two branch pipes 3 533, the fourth main pipe 51 is connected to two branch pipes 4 534, and the fifth main pipe 51 is connected to two branch pipes 535. Figure 4 Arrange them in order.

[0038] As a preferred setting, the pneumatic boost control system sprays a group of air ducts at a time interval of 5 seconds, and the air intake of several branch pipes 53 is circulated in sequence. The compressed air storage tank is drained and the air is delivered to the front of the solenoid valve 52. When the high-temperature material falls and accumulates, the pneumatic boost system is turned on to complete the automatic transportation of the material. After the system stops, the system power is cut off and the air source is closed.

[0039] like Figure 2 As shown, in the present invention, the angle a between the bottom plate 4 and the horizontal plane is in the range of 30-45°.

[0040] like Figure 2 As shown, in the present invention, the angle b between the soot blowing hole 41 and the bottom plate 4 is in the range of 30-45°.

[0041] Theoretically, the installation angle of the bottom plate 4 and the angle of the soot blowing hole 41 need to be designed according to the above parameters. However, in order to further enhance the blowing performance and reduce the possibility of clogging of the soot blowing hole 41, an optimized design is further made.

[0042] like Figure 2As shown, when the bottom plate 4 is tilted on the slope surface 3, no matter what the angle a between the bottom plate 4 and the horizontal plane is, the soot blowing hole 41 and the horizontal plane are at least parallel. With this setting, when the material falls vertically, it can avoid the material from falling directly into the soot blowing hole 41 as much as possible to cause blockage. And when the material falls, the bottom plate 4 will rotate a certain angle and have a tendency to move downward, so the soot blowing hole 41 will present a tilted downward angle, further avoiding the material from falling into the soot blowing hole 41. In addition, the soot blowing hole 41 is designed at this angle, which is not in vertical contact with the material, but has a certain tilted angle, so the air blown out through the soot blowing hole 41 acts on the material obliquely, and the material can be blown down more easily. With this setting, the compressed air can achieve more material blowing with a smaller pressure, that is, the blowing intensity is greater, the blowing effect is better, and the material is not easy to cause accumulation.

[0043] like Figure 3 As shown, several groups of soot blowing holes 41 are arranged along the width direction of the bottom plate 4, the distance between the soot blowing holes 41 on both sides of the bottom plate 4 and the middle soot blowing holes 41 is recorded as d1, and the distance between several groups of soot blowing holes 41 in the middle of the bottom plate 4 is recorded as d2, and d1 is greater than d2. Based on the concentration of the area where the materials fall, the soot blowing holes 41 in the middle of the bottom plate 4 are denser to cope with the blowing of more materials.

[0044] Furthermore, a maintenance manhole 2 is provided on one side of the feed port 11 .

[0045] like Figure 5 , Figure 6 As shown, a mounting block 8 is provided at the bottom of the feed port 11, and an arc-shaped mounting groove 81 is provided in the mounting block 8. A rotating shaft 42 is provided at one end of the bottom plate 4, and the rotating shaft 42 is hinged at both sides of the mounting groove 81. An elastic sealing ring 9 is sleeved on the rotating shaft 42, and both ends of the elastic sealing ring 9 are arranged closely to the two end surfaces of the bottom plate 4, and the outer wall of the elastic sealing ring 9 is arranged closely to the mounting groove 81. This design can prevent the material from penetrating into the mounting groove 81 and causing leakage.

[0046] Further, the bottom end of the mounting block 8 is provided with an air duct penetration hole 82. When installing the air duct, it can be installed through the air duct penetration hole 82 without leaking materials, which is convenient and quick.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
