Abstract
The utility model discloses a coal powder spraying pipeline filter device conductive to reducing blockage and easy to clean. The filter device comprises a filter shell and a filter plate assembly, wherein filter neck bodies are arranged at two ends of the filter shell, and connecting flanges are arranged at the end parts of the filter neck bodies; the filter shell is in a cavity body structure expanded from two ends to the center, the filter plate assembly is vertically arranged at the maximum diameter in a filter cavity body, a filter plate shell is integrated with the filter shell and is naturally and transitionally connected with the filter shell, and the inner wall of the filter shell is smooth and round. According to the filter device, the integral structure is adopted, the natural transition fit is realized, and the inner wall is smooth and round, so that the problem of blockage easily caused by rough fixing and connecting parts of a multi-part combination structure in the prior art is solved; the filter device can be formed once by casting high-wear-resistant materials or a high-wear-resistant lining layer is additionally arranged at the inner wall of the cavity body, so that the wear resistance of the whole filter is improved, the maintenance-free time of the filter is prolonged, the repair amount is reduced, the production cost is reduced, and the economic benefit of enterprises is increased.
Description
Technical field
The utility model belongs to smelting equipment technical field, is specifically related to a kind of simple in structurely, and working stability contributes to reduce the breeze blowing pipeline filter that blocks and be easy to cleaning reliably.
Background technology
In steel manufacture process, pulverized coal injection is to form the important step of producing, and coal fine filter is in coal powder injection pipeline, to be used for filtering cleaning foreign material, prevents the device that pipeline and miscellaneous equipment stop up.Be one of key equipment in bf coal injection system, its mounting structure directly affects the normal production of blast furnace.Strainer is generally two side flange types of attachment, bipyramid butt welding, and centre is screen plate, screen plate adopts can load and unload form, bipyramid is weldering junction structure, when this inside configuration welding, due to narrow space, can produce welding step, weld seam is inhomogeneous, causes interior finish poor, has a strong impact on the mobility of coal dust, moreover when welding due to the deviation of angle, cause filtration unit body to be blown logical by coal dust and pressurized air (nitrogen) mixed airflow; Press blast furnace powder sending quantity 15-20 per hour ton and calculate, the life cycle of filtration unit is only 2-3 month, need to change frequently like this strainer, causes the production cost of enterprise to increase, and increases the weight of maintainer and changes cleaning work.For this reason, development is a kind of simple in structure, working stability, and the breeze blowing pipeline filter that contributes to minimizing obstruction and be easy to clear up that extends life cycle and good filtration effect is the effective way addressing this problem.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, and working stability is reliable, and what life cycle was long contributes to reduce the breeze blowing pipeline filter that blocks and be easy to cleaning.
The purpose of this utility model is achieved in that and comprises filter body and screen plate assembly, and described filter body two ends arrange strainer neck body, and strainer neck body end arranges joint flange; Described filter body is the cavity configurations of two ends to center hole enlargement, and screen plate assembly is vertically installed in maximum diameter place in strainer cavity, and described screen plate assembly comprises screen plate housing and screen plate, and both slipper seals coordinate; The screen plate housing supporting plate that arranges suitable for reading, supporting plate and pressing plate are sealed and matched by backing plate, depression bar, thimble, and described screen plate housing and filter body are one-piece construction, and natural transition connection and inwall are bright and clean mellow and full.
The utility model adopts one-piece construction, does not have seam, natural transition fit between each parts, inwall is bright and clean mellow and full, has overcome the multi-part unitized construction of prior art, and the affixed position that is connected is coarse, especially exist and connect the not smooth finish of inwall that step causes, the problem of the obstruction easily causing.Both can select the material of high abrasion by casting once shaped, also can increase at cavity inner wall the lining of high abrasion, improve the wear resisting property of strainer entirety, extend its non-maintaining phase, reduce maintenance capacity, reduce production costs, improve Business Economic Benefit.
Brief description of the drawings
Fig. 1 is the utility model one-piece construction cross-sectional schematic;
Fig. 2 is the left view of Fig. 1;
In figure: 1-strainer cavity, 2-filter body, 3-strainer neck body, 4-joint flange, 5-backing plate, 6-pressing plate, 7-depression bar, 8-bearing pin, 9-thimble, 10-screen plate, 11-supporting plate.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but never in any form the utility model is limited, and any conversion of doing based on the utility model training centre, all falls into the utility model protection domain.
As shown in Figure 1 and 2, the utility model comprises filter body 2 and screen plate assembly, and described filter body 2 two ends arrange strainer neck body 3, and strainer neck body 3 ends arrange joint flange 4; Described filter body 2 is the cavity configurations of two ends to center hole enlargement, and screen plate assembly is vertically installed in the interior maximum diameter of strainer cavity 1 place, and described screen plate assembly comprises screen plate housing and screen plate 10, and both slipper seals coordinate; The screen plate housing supporting plate 11 that arranges suitable for reading, supporting plate 11 is sealed and matched by backing plate 5, depression bar 7, thimble 9 with pressing plate 6, and described screen plate housing and filter body 2 are one-piece construction, and natural transition connection and inwall are bright and clean mellow and full.
Described filter body 2 wall thickness are 16-20mm.
Described filter body 2 two ends arrange strainer neck body 3, both affixed cooperations, and seam crossing inwall is bright and clean mellow and full.
Described filter body 2 inwalls arrange high abrasion lining.
Described filter body 2, screen plate housing and strainer neck body 3 are seamless continuous entirety, and the transition of inwall Nature Link nature is smooth mellow and full.
Described filter body 2 is greater than the thickness near screen plate place near the wall thickness at neck body position.
Described filter body 2 is greater than the thickness 30% near screen plate place near the wall thickness at neck body position.
principle of work of the present utility model and process:
The utility model adopts one-piece construction, does not have seam, natural transition fit between each parts, inwall is bright and clean mellow and full, has overcome the multi-part unitized construction of prior art, and the affixed position that is connected is coarse, especially exist and connect the not smooth finish of inwall that step causes, the problem of the obstruction easily causing.Both can select the material of high abrasion by casting once shaped, also can increase at cavity inner wall the lining of high abrasion, improve the wear resisting property of strainer entirety, extend its non-maintaining phase, reduce maintenance capacity, reduce production costs, improve Business Economic Benefit.
