Abstract
The invention discloses a scale-type dryer sealing device comprising an outer sealing ring, sealing flanges, press blocks, temperature control devices, cylinder sheaths, sealing block rings and inner retaining rings, wherein the cylinder sheaths are arranged on a cylinder, one end of each temperature control device is closely clung to the cylinder sheaths, the other end of each temperature control device locks each the press block through a bolt to fix the press block on each sealing flange, the sealing flanges are welded on the outer sealing rings and are matched with the sealing block rings arranged at the cylinder for use, and the cylinder is further provided with the inner retaining rings. Through the improvement, the scale-type dryer sealing device has the advantages that the sealing performance is reinforced, the abrasion of each stainless steel sheet is less, the service life is prolonged, the cost is low and the maintenance is simple and convenience.
Description
Technical field
The present invention relates to a kind of drying plant, be specifically related to flake type dryer sealing device in composite fertilizer's production.
Background technology
Dryer is widely used in the drying materials of industries such as cement, building materials, chemical industry, grain, composite fertilizer's production, in order to control the temperature of oven dry, dispose thermocouple at charging/discharging device, can show the variations in temperature of dryer input and output material by thermometer, for the operating temperature of controlling better in the cylindrical shell provides foundation.Dryer mainly is made up of parts such as cylindrical shell device, front and back tugboat device, charging/discharging device, transmission device and gear covers.
Composite fertilizer produces the basic industry as chemical industry, and its technological process can be divided into feed proportioning, raw material stirring, raw material granulation, particle oven dry, particle cooling, gradation, finished product coating, end product packing usually.In this series of process process, the granulated fertilizer that the particle stoving process is mainly made comminutor is sent into dryer, with intragranular moisture oven dry, increases granule strength, is convenient to preserve.Drying plant mainly added hot-air by combustion furnace during composite fertilizer produced, and utilized blower fan that hot-air is delivered in the dryer, and then control oven dry built-in temperature, dehumidified, and reached drying effect.And dryer feed end seal form can be divided into labyrinth type, axial contact, malleation sealing gland formula etc.
At present, dryer adopts labyrinth sealing more, but influenced by high temperature and start-stop car, easily cause the distortion of sealing flange and T shape sealing ring to kill, sealed outer ring is also squeezed bad, causes stopping production, in case damage, there are problems such as maintenance bothers, down time is long in this seal form, brings loss to company.
Summary of the invention
The purpose of this invention is to provide a kind of flake type dryer sealing device, its characteristics formula: simple in structure, cost is little, easy to maintenance.
In order to address the above problem, the technical solution used in the present invention is: a kind of flake type dryer sealing device, comprise sealed outer ring, sealing flange, briquetting, attemperating unit, the cylindrical shell sheath, Sealing shield ring and interior collet, described cylindrical shell sheath is arranged on the cylindrical shell, and attemperating unit one end and cylindrical shell sheath are close to, the other end is fixed on the sealing flange by bolt locking briquetting, described sealing flange is welded on the sealed outer ring, and the use that matches with Sealing shield ring on being arranged on cylindrical shell of described sealing flange also is provided with interior collet on the described cylindrical shell.
Described attemperating unit is the stainless steel spring steel disc, can form an arc shape because adopt elastic steel disc to be arranged on like this between sealing flange and the cylindrical shell sheath, described attemperating unit is provided with several, and pressing one for one between the adjacent attemperating unit, just form flake type, can well reach the effect of sealing, and the steel disc length of described attemperating unit is 350mm, width is 200mm.
The invention has the beneficial effects as follows: after this practicality improved, sealing property was strengthened, the stainless steel substrates wearing and tearing are less, the prolongation in service life, low, the easy to maintenance convenience of cost.
Description of drawings
Fig. 1 is structural representation of the present invention.
Wherein: 1, sealed outer ring, 2, sealing flange, 3, briquetting, 4, attemperating unit, 5, the cylindrical shell sheath, 6, cylindrical shell, 7, Sealing shield ring, 8, interior collet.
The specific embodiment
The invention will be further described below in conjunction with embodiment and accompanying drawing.
As shown in Figure 1, a kind of flake type dryer sealing device, comprise sealed outer ring 1, sealing flange 2, briquetting 3, attemperating unit 4, cylindrical shell sheath 5, Sealing shield ring 7 and interior collet 8, described cylindrical shell sheath 5 is arranged on the cylindrical shell 6, and attemperating unit 4 one ends and cylindrical shell sheath 5 are close to, the other end is fixed on the sealing flange 2 by bolt locking briquetting 3, described sealing flange 2 is welded on the sealed outer ring 1, the use that matches with Sealing shield ring 7 on being arranged on cylindrical shell 6 of described sealing flange 2, collet 8 in also being provided with on the described cylindrical shell 6.
Described attemperating unit 4 is the stainless steel spring steel disc, can form an arc shape because adopt elastic steel disc to be arranged on like this between sealing flange 2 and the cylindrical shell sheath 5, described attemperating unit 4 is provided with several, and pressing one for one between the adjacent attemperating unit 4, form flake type, can well reach the effect of sealing, and the steel disc length of described attemperating unit is 350mm, width is 200mm.
Its whole use is as follows: weld cylindrical shell sheath 5 and Sealing shield ring 7 on the cylindrical shell 6 of dryer earlier, then the sealed outer ring 1 that fixes burn-on one the circle sealing flange 2, by briquetting 3 attemperating unit 4 one ends are fixed by bolts on the sealing flange 2, and every adjacent stainless steel spring steel disc in the same direction one pressing one, the other end of stainless steel spring steel disc touch on the cylindrical shell sheath 5 when cylindrical shell rotates under the effect of self toughness tightly, thereby reach sealing function, because blocks of stainless steel spring steel disc is fixing by the bolt briquetting, the spitting image of the scale of fish, therefore can be called the flake type sealing to this seal form in shape.Its cost is low, sealing property strong, wearing and tearing are little, and replacing is got up simple and convenient, is a kind of better seal form, and cost is low, the economic benefit height.
