Abstract
The invention discloses a novel spring type sealing structure device of an annular cooling machine. The sealing structure device comprises a sliding groove, a plurality of springs and a plurality of sliding blocks, wherein the springs and the sliding blocks are arranged inside the sliding groove and are arranged in a one-to-one correspondence mode along the length direction of the sliding groove, lower ends of the springs are fixed on spring fixing blocks arranged inside the sliding groove, and upper ends of the springs are fixed on the sliding blocks. At the upper opening position of the sliding groove, a sealing part is arranged on connection portions of the sliding blocks and the sliding groove, and upper ends of the sliding blocks are tapered. A base is arranged at the bottom of the sliding groove, the sliding groove is welded on the base, and a plurality of fixing bolts are arranged at two edges of the base along the length direction of the base. By the aid of the device, the phenomena of sintered static seal air leakage and material leakage caused by abrasions of a rubber type sealing structure of the annular cooling machine and thermal expansion and cold contraction of a trolley are avoided, and fluctuations and potential safety hazards during production are reduced.
Description
Technical field
The present invention relates to a kind of seal arrangement, particularly a kind of novel spring type sealing device for annular cooling machine.
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 a kind of continuously production process, the sintering deposit production process, except roasting and finished product, also comprises mainly that sintering deposit is former, fuel batching, batch mixing, cooling and screening etc.Wherein, sintering deposit is cooling is requisite production process in sintering process, is generally by central cooler or belt-cooling machine equipment, to be undertaken coolingly, and its cooling procedure is mainly carried out air blast by blower to circular cooler trolley and carried out.For central cooler, due to its trolley structure and the ring gauze technological principle demand of putting, in the sintering cooling procedure, need circular cooler trolley is sealed in case leak-stopping wind, and existing central cooler sealing configuration is mostly rubber sealing structure, the liquid sealing structure form that adopts is also arranged, and its central cooler outer shroud static seal is also the rubber sealing structure form adopted.Due to the reason that rubber weares and teares and chassis itself expands with heat and contract with cold, be easy to cause the sintering static seal to leak out, leak material, sometimes air leak rate of air curtain can reach 50% level, so high air leak rate of air curtain causes the sintering deposit cooling effect not good enough, finally cause the scaling loss such as finished product system belt, screening plant serious, to safety, bring larger hidden danger, also can bring very large impact to production.
Summary of the invention
Problem solved by the invention has been to provide a kind of novel spring type sealing device for annular cooling machine, this invention can be avoided because sintering static seal that situation that central cooler rubber-type sealing configuration wearing and tearing and chassis itself expand with heat and contract with cold causes leaks out and leaks the generation of material phenomenon, and the reduction production process fluctuates and reduces the production process potential safety hazard.
For solving the problems of the technologies described above, a kind of novel spring type sealing device for annular cooling machine of the present invention, it is characterized in that, the spring and the slide block that comprise chute and be arranged at chute inside, described spring and slide block are a plurality of, described spring and slide block are along the length direction corresponding setting one by one of its chute, and the lower end of described spring is fixed on the inner fixing spring fixed block arranged of chute, 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 the material problem of leaking out caused due to factors such as the distortion of the steel structure such as chassis, guide rails assembling error, chassis sideslips in central cooler continuous operation process; This device is convenient for installation and maintenance, long service life, and maintenance cost is low, can utilize servicing machine meeting installation, reduces the central cooler air leak rate of air curtain, reduces production accident, improves the production process reliability.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the present invention and the chassis structural representation while being used in combination;
In figure: 1-chute, 2-spring, 3-slide block, 4-spring fixed block, 5-base, 6-fixing bolt, 7-trolley breast plate, 8-sealing plate, 9-Sealing, 10-chassis pedestal.
Embodiment
For clearly demonstrating technical characterstic of the present invention, 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, spring 2 and slide block 3 that it comprises chute 1 and is arranged at chute 1 inside, described spring 2 and slide block 3 are a plurality of, described spring 2 and slide block 3 are along the length direction corresponding setting one by one of its chute 1, the lower end of described spring 2 is fixed on the inner spring fixed block 4 arranged of chute 1, 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 the design easy disassembly like this.
As optimization, the upper end of slide block 3 is set to taper, can reduce like this friction between the sealing plate 8 arranged on slide block 3 and trolley breast plate 7.
As further optimization, the upper opening place of described chute 1, the binding site of slide block and chute 1 arranges Sealing 9.Between chute 1 and slide block, sealing with Sealing 9 is mainly to prevent that dust from entering in chute 1, to affect the movement of slide block 3.
During use, this device is installed on to the edge of chassis pedestal 10, the sealing plate 8 arranged on upper end and trolley breast plate 7 coordinates and forms confined space, and under the effect of spring 2, slide block 3 and sealing plate 8 close contacts, can effectively prevent from leaking out.
In addition, when chassis ran to bend, part slide block 3 separated with sealing plate 8, also can not affect its blanking, and can not cause wearing and tearing during blanking; In the normal operation process that goes in ring, the gap that the thermal distortion of chassis and trolley breast plate, the installation of guide rail injustice, chassis sideslip etc. cause, can pass through the spring effective compensation, slide block and sealing plate remained and contact, and forms enclosed space, prevents from leaking out when chassis.
Except the described technical characteristics of above-mentioned specification, be the known technology of those skilled in the art.
