Abstract
The invention discloses a kind of novel spring type central cooler sealing structure unit, it comprises chute and is arranged at spring and the slide block of chute inside, described spring and slide block are multiple, spring and slide block are arranged along the length direction one_to_one corresponding of its chute, the lower end of spring is fixed on the fixing spring fixed block of chute inside setting, and the upper end of spring is fixed on slide block.The upper opening place of described chute, the binding site of slide block and chute arranges Sealing, and the upper end of slide block is set to taper.The bottom of described chute arranges base, and chute is welded on base, and the both sides of described base arrange some fixing bolts along its length.The sintering static seal that the present invention can avoid the situation of expanding with heat and contract with cold due to the wearing and tearing of central cooler rubber-type sealing configuration and chassis itself to cause leaks out and leaks the generation of material phenomenon, reduces production process fluctuation and reduces production process potential safety hazard.
Description
Technical field
The present invention relates to a kind of seal arrangement, particularly a kind of novel spring type central cooler sealing structure unit.
Background technique
The ironmaking system of Iron And Steel Industry, need to produce sintering deposit for blast furnace, and sintering deposit production is the previous process of blast furnace ironmaking, it is one continuously production process, sintering deposit production process except roasting and finished product, also mainly comprise that sintering deposit is former, fuel batching, batch mixing, cooling and screening etc.Wherein, sintering deposit cooling is requisite production process in sintering process, generally cools by central cooler or belt-cooling machine equipment, and its cooling procedure is mainly carried out air blast by blower to circular cooler trolley and carried out.For central cooler, due to the technological principle demand that its trolley structure and ring gauze are put, need to seal circular cooler trolley in case leak-stopping wind in sintering cooling procedure, and existing central cooler sealing configuration is mostly rubber sealing structure, also have the liquid sealing structure form of adopting, its central cooler outer shroud static seal is also the rubber sealing structure form adopted.Due to the reason that rubber wearing and tearing and chassis itself expand with heat and contract with cold, be easy to cause sintering static seal to leak out, leak material, sometimes air leak rate of air curtain can reach the level of 50%, so high air leak rate of air curtain causes sintering deposit cooling effect not good enough, finally cause the scaling loss such as finished product system belt, screening plant serious, bring larger hidden danger to safety, also can bring very large impact to production.
Summary of the invention
Problem solved by the invention there is provided a kind of novel spring type central cooler sealing structure unit, the sintering static seal that this invention can avoid the situation of expanding with heat and contract with cold due to the wearing and tearing of central cooler rubber-type sealing configuration and chassis itself to cause leaks out and leaks the generation of material phenomenon, reduces production process fluctuation and reduces production process potential safety hazard.
For solving the problems of the technologies described above, a kind of novel spring type central cooler of the present invention sealing structure unit, it is characterized in that, comprise chute and be arranged at spring and the slide block of chute inside, described spring and slide block are multiple, described spring and slide block are arranged along the length direction one_to_one corresponding of its chute, and the lower end of described spring is fixed on the fixing spring fixed block that chute inside arranges, and the upper end of spring is fixed on slide block.
The upper opening place of described chute, the binding site of slide block and chute arranges Sealing.
The upper end of described slide block is set to taper.
The bottom of described chute arranges base, and chute is welded on base, and the both sides of described base arrange some fixing bolts along its length.
The invention has the beneficial effects as follows: this device can effectively solve in the continuous operation process of central cooler due to material problem of leaking out that the factors such as steel structure distortion, guide rails assembling error, chassis sideslip such as chassis cause; This device is convenient for installation and maintenance, long service life, and maintenance cost is low, can utilize servicing machine meeting installation, reduce central cooler air leak rate of air curtain, reduce production accident, improve production process reliability.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the present invention and chassis structural representation when combinationally using;
In figure: 1-chute, 2-spring, 3-slide block, 4-spring anchor block, 5-base, 6-fixing bolt, 7-trolley breast plate, 8-sealing plate, 9-Sealing, 10-chassis pedestal.
Embodiment
For technical characterstic of the present invention can be clearly demonstrated, below by an embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
As shown in Figure 1 and Figure 2, the invention provides a kind of novel spring type central cooler sealing structure unit, it comprises chute 1 and is arranged at spring 2 and the slide block 3 of chute 1 inside, described spring 2 and slide block 3 are multiple, described spring 2 and slide block 3 are arranged along the length direction one_to_one corresponding of its chute 1, the lower end of described spring 2 is fixed on the spring anchor block 4 of chute 1 inside setting, and the upper end of spring 2 is fixed on slide block 3.The bottom of described chute 1 arranges base 5, and chute 1 is welded on base 5, and the both sides of described base 5 arrange some fixing bolts 6 along its length.This device is changed in such design easy disassembly.
As optimization, the upper end of slide block 3 is set to taper, can reduce the friction between sealing plate 8 that slide block 3 and trolley breast plate 7 are arranged like this.
As further optimization, the upper opening place of described chute 1, the binding site of slide block and chute 1 arranges Sealing 9.Carrying out sealing with Sealing 9 between chute 1 and slide block mainly prevents dust from entering in chute 1, to affect the movement of slide block 3.
During use, this device is installed on the edge of chassis pedestal 10, upper end coordinates with the sealing plate 8 that trolley breast plate 7 is arranged and forms confined space, and under the effect of spring 2, slide block 3 and sealing plate 8 close contact, can effectively prevent from leaking out.
In addition, when chassis runs to bend, part slide block 3 is separated with sealing plate 8, also can not affect its blanking, and can not cause wearing and tearing during blanking; When chassis goes in ring in operation process normal, the gap that the thermal distortion of chassis and trolley breast plate, the installation injustice, chassis sideslip etc. of guide rail cause, by spring effective compensation, makes slide block and sealing plate remain and contacts, and forms enclosed space, prevents from leaking out.
Except the technical characteristics described in above-mentioned specification, be the known technology of those skilled in the art.
