Abstract
A filter tube assembly device in a coal chemical device comprises a tube plate, stop blocks, stainless steel screens, baffles, short tubes and a plurality of filter tubes. The filter tube assembly device is structurally characterized in that the plurality of filter tubes are evenly arranged on the tube plate, upper parts of the filter tubes are connected with the tube plate through thread structures, the stop blocks are arranged at positions where the lower surface of the tube plate and the filter tubes are connected, upper and lower parts of the filter tubes adopt tube structures with different thicknesses, the short tubes are arranged at the upper parts of the filter tubes, lower ends of the filter tubes are connected with the baffles, and the stainless steel screens are connected on the periphery of filter tube parts below the tube plate. The filter tube assembly device in the coal chemical device is relatively simple in machining and economical in manufacturing; by means of the structure, the production cost can be reduced substantially, the production cycle is shortened, and the application of the technology to the coal chemical device is promoted; and the filter tube assembly device also has the advantages of economy, convenience in replacement and cleaning and short processing cycle.
Description
Technical field
The utility model relates to a kind of screen pipe assembly apparatus, relates in particular to screen pipe assembly apparatus in a kind of coal chemical engineering equipment.
Background technology
Take coal as primary raw material, produce synthetic ammonia, utilize the ammonia of output further to produce urea and soda ash product.By building, take the connection alkali process units that coal and salt is raw material, simple resource economic restructure is changed into derived energy chemical type economy, to realize economic structural adjustment.This is one of important means of adjusting coal resource enrichment regional economic structure, and unstripped gas filter is one of non-standard equipment in this project synthetic ammonia installation, and its working media is raw gas, dust (H

3, Ar) etc., the Main Function of equipment is that gas cleaning filters.Screen pipe assembly is the vitals of purification filtering, mainly screen pipe, nipple joint, block, stainless steel cloth and baffle plate, consists of, and pipe component count is 360.But the structure of current screen pipe assembly can not be suitable for above-mentioned production completely, current improving one's methods is to change former pipe fitting, and in the thinking of its boring, and perforate is too intensive on pipe fitting, there is the problem that difficulty of processing is large, the cycle is long, cost is high, will greatly increase the cycle of producing.
Summary of the invention
The purpose of this utility model is to provide screen pipe assembly apparatus in a kind of coal chemical engineering equipment, and it has advantages of that processing is simple and changes easy to clean.
The utility model is achieved like this, it comprises tube sheet, block, stainless steel cloth, baffle plate, short tube and screen pipe, it is characterized in that several screen pipes are evenly arranged on tube sheet, the top of screen pipe is connected by helicitic texture with tube sheet, the lower surface of tube sheet and the junction of screen pipe are provided with block, the upper and lower of screen pipe is the pipe structure of uniform thickness not, wherein, the top of screen pipe is short tube, the lower end of screen pipe is connected with baffle plate, and the periphery that is positioned at the screen pipe part of tube sheet below is connected with stainless steel cloth.
Technique effect of the present utility model is: this novel practical provides a kind of processing relatively simple, manufacture screen pipe assembly apparatus in comparatively economic coal chemical engineering equipment, adopt this structure can significantly reduce production costs, shorten the production cycle, promoted the application of this technology on coal chemical engineering equipment.It also has economy, changes easy to clean and short advantage of process-cycle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model screen pipe.
The specific embodiment
As shown in Figure 1, the utility model is achieved like this, it comprises tube sheet 1, block 2, stainless steel cloth 3, baffle plate 4, short tube 5 and screen pipe 6, its design feature is that several screen pipes 6 are evenly arranged on tube sheet 1, the top of screen pipe 6 is connected by helicitic texture with tube sheet 1, the junction of the lower surface of tube sheet 1 and screen pipe 6 is provided with block 2, the upper and lower of screen pipe 6 is the pipe structure of uniform thickness not, wherein, the top of screen pipe 6 is short tube 5, the lower end of screen pipe 6 is connected with baffle plate 4, the periphery that is positioned at screen pipe 6 parts of tube sheet 1 below is connected with stainless steel cloth 3.
Processing of the present utility model and operation principle are such, open 360 holes on tube sheet 1, mainly play support and fixing screen pipe 6.The structure of screen pipe 6 as shown in Figure 2.After 360 screen pipes 6 are good with baffle plate 4 welding respectively, at screen pipe 6 and baffle plate 4 surface wrapping one deck 300 order stainless steel cloths 3, and then wrapping one deck 200 order stainless steel cloths 3, the effect of playing screening and filtering.During stainless steel cloth 3 wrapping, the overlapping 10mm of junction palpus left and right, sews up closely, is inserted in after screen pipe 6, then is spun on tube sheet 1, with nipple joint (similar with nut), fixes.Consider that screen pipe 6 bottom the number of openingss are more, so the selection of its thickness is more crucial.The too thin machine-shaping that is unfavorable for screw thread of tube wall, too thick workload and the work difficulty that has strengthened again perforate of tube wall.The aspect such as compound material, manufacture factor considers, by the upper and lower of screen pipe 6, be the pipe structure of uniform thickness not, and perforate later and short tube 5 in bottom is welded into a whole;
When work, after stainless steel cloth 3 filtrations of the media such as raw gas by screen pipe 6 peripheries, bottom, enter, remove the impurity such as dust in gas, gas after filtration is upwards discharged through tube sheet 1 from short tube, because screen pipe 6 is threaded with tube sheet 1, screen pipe 6 under can regular dismounting, changes or cleans stainless steel cloth 3 and screen pipe 6.
