Abstract
The utility model provides a device implementing the dynamic sealing by utilizing the magnetic hydraulic sealing medium, which is composed of moving baffle plates arranged on the baffle plates on the both sides of a sintering pallet, a fixed baffle plate arranged on a fixed platform frame, magnetic liquid arranged between the fixed baffle plate and the moving baffle plates, and a permanent magnet arranged on the fixed baffle plate. Compared with other sealing devices applied at present, the technical progress effects of the device implementing the dynamic sealing by utilizing the magnetic hydraulic sealing medium are in that 1, the sealability is good; the sealing position can realize zero leakage; the sintering machine can greatly reduce the air leakage rate, and the energy saving and the consumption reducing are visible; 2, the structure is simple; the exact fit is not needed; the gap of the sealing position of the magnetic field is big and can automatically regulate dynamically so that the trolley still can keep the excellent sealability when a certain deformation is generated in use; 3, the installation is simple; most of positions are completed by adopting the welding or the hinging; 4, the maintenance is convenient; the operability is strong; after the installation is completed, because the moving baffle plates are not contacted with the fixed baffle plate, each component is not easy to be damaged; the repair amount can be greatly reduced; the periodic observation of the magnetic liquid is served as the daily maintenance work, and the magnetic liquid can be complemented in time.
Description
Technical field
The utility model relates to magnetic field, a kind of sintering machine slit seal arrangement, is mainly used in the dynamic seal (packing) in the slit between the sintering pallet and bellows in the smelting iron and steel, belongs to metallurgical supporting water-tight equipment technical field.
Background technique
Problems such as at present, the sintering machine ubiquity of China's smelter the energy consumption height, efficient is low, utilization factor is low, poor product quality.Reason is that sintering machine leaks out, and air leak rate of air curtain is generally about 60%.Whole nation sintering plant loses more than 4,000,000,000 yuan every year for this reason, and has strengthened environmental burden.This harmful leak out mainly occur between chassis and the slideway and trolley body between (account for all leak out more than 60%).Sealing between chassis and the bellows, basically be to adopt " slide block-slideway " formula seal arrangement, this seal arrangement is because the defective on itself designing, add the influence of the factor such as collision, abrasion deformation of the fluctuation of running ambient temperature and car body, air leak rate of air curtain is very high.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and a kind of device that utilizes the dynamic seal (packing) of magnetic fluid sealing media implementation is provided, and to reduce air leak rate of air curtain, lowers energy consumption, increases economic efficiency.
The technical solution of the utility model is achieved in that magnetic field, this sintering machine slit seal arrangement, it is characterized in that seal arrangement is by the moving stop that is provided with on sintering pallet two lateral retaining plates, fixed rack and the fixed dam that upward is provided with thereof, the magnetic liquid that is provided with between fixed dam and the moving stop, the permanent magnet that is provided with on the fixed dam constitutes.
The fixed dam transverse section of magnetic field, described sintering machine slit seal arrangement is L shaped or U-shaped, splendid attire magnetic seal liquid medium in the baffle plate.
In the fixed dam of magnetic field, described sintering machine slit seal arrangement dividing plate is set.
Between the fixed rack of magnetic field, described sintering machine slit seal arrangement and the side of fixed dam permanent magnet is set.
On the moving stop of magnetic field, described sintering machine slit seal arrangement stiffening rib is set.
The fixed dam periphery of magnetic field, described sintering machine slit seal arrangement is provided with waterway.
Magnetic field, described sintering machine slit seal arrangement, a right angle side that it is characterized in that described moving stop are positioned within the magnetic seal liquid medium of fixed dam does relative movement.
The utility model is compared the technological progress effect with present applied other seal arrangement and shown: 1, good airproof performance: " 0 " leakage can be realized in the sealing position.Sintering machine can reduce air leak rate of air curtain significantly, and is significantly energy-saving and cost-reducing.2, simple in structure: do not need accurate cooperation, but sealed department interdigit crack, magnetic field is big and automatic dynamic is regulated, this when using process produces certain deformation, still can keep good sealing property for chassis.3, install simply: welding or hinged finishing are adopted in most of position; 4, easy to maintenance, exploitativeness is strong: after the installation, because moving stop does not contact with fixed dam, so each parts is not fragile, amount of maintenance can reduce significantly; As line service is the routine observation magnetic liquid, and that in time replenishes gets final product.
