Abstract
The utility model discloses a control system of a blowback pulse valve used in a blast furnace bag-type dust collector. The blast furnace bag-type dust collector comprises a plurality of box bodies, wherein a plurality of pulse valves are arranged in each box body; the pulse valves are divided into a plurality of groups; each group of pulse valves is correspondingly controlled by a relay; the relays in each group are connected in parallel with a PLC (Programmable Logic Controller) output point; the system further comprises a plurality of pulse valve control points; each pulse valve control point is connected to one PLC output point, and the relays are sequentially connected to the pulse valve control points. For the blast furnace bag-type dust collector with 8 box bodies, the control in the prior art which needs 128 PLC output points can be realized only by 24 PLC output points, so that the number of output modules is greatly reduced, and the cost is reduced.
Description
Technical field
The utility model relates to a kind of blowback pulse valve control system, is specifically related to a kind of bf bag filter blowback pulse valve control system.
Background technology
At present, bf bag filter is pulse valve of an output point band by the PLC module with the blowback pulse valve, because pulse valve quantity is more, for example, bf bag filter comprises 8 casings, and each casing has 16 pulse valves, so, just need the output point of 128 PLC modules, required PLC module number is many, and cost is high.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, a kind of furnace cloth bag dust-removing bf bag filter blowback pulse valve control system being provided.
For achieving the above object, the utility model adopts following technical proposals:
A kind of bf bag filter blowback pulse valve control system, described pulse valve is divided into some groups, and every group pulse valve correspondence is by a Control, and every group relay is connected in parallel to a PLC output point; This system also comprises several pulse valve control points, and each pulse valve control point all is connected to a PLC output point, and described relay is connected to the pulse valve control point successively.
Described pulse valve is 16, is divided into 4 groups, and every group pulse valve correspondence is by a Control, and these 4 relays are connected in parallel to a PLC output point; This system also comprises 16 pulse valve control points, and each pulse valve control point all is connected to a PLC output point, and described relay is connected to the pulse valve control point successively, and 4 pins of each relay are connected to 4 pulse valve control points successively.
Described pulse valve control point is auxiliary reclay.
Operation principle of the present utility model:
4 pulse valves of each Control, per 4 relays are connected in parallel to a PLC output point, thus, 8 casings need 8 PLC output points altogether, add 16 16 PLC output points that the pulse valve control point is corresponding, 8 interior pulse valves of casing need to connect altogether 24 PLC output points and realize control.
The beneficial effects of the utility model:
For a bf bag filter with 8 casings, only need 24 PLC output points just can realize the control that existing 128 PLC output points are realized.The utility model has greatly reduced the quantity of output module, has saved cost.
Description of drawings
Fig. 1 is the connection diagram of pulse valve control point and PLC output point;
Fig. 2 is the utility model structural representation;
Fig. 3 is schematic diagram of the present utility model;
Wherein Q01～Q24 is the PLC output point, and K01～K48 is relay.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further set forth, should be noted that following explanation only is in order to explain the utility model, its content not to be limited.
Bf bag filter comprises 8 casings, and namely 1# shown in Figure 2～8# casing is provided with 16 pulse valves in each casing, and pulse valve is divided into 4 groups, and every group pulse valve correspondence is by a Control, and every group relay is connected in parallel to a PLC output point.That is to say, 4 pulse valves of each Control, per 4 relays are connected in parallel to a PLC output point, thus, 8 casings need 8 PLC output points altogether, add 16 PLC output points corresponding to 16 pulse valve control points (Fig. 1), 8 interior pulse valves of casing need to connect altogether 24 PLC output points and realize control.
Concrete schematic diagram as shown in Figure 3.During the blowback of 1# casing, the output of 1# case control PLC output point, at this moment 4 of the 1# casing actuatings of relay, the PLC output point at 16 pulse valve control points moves successively, and the blowback of 1# casing is finished in 16 of the 1# casing also successively actions of pulse valve like this.2#～8# casing blowback principle is identical with the 1# casing.
Although above-mentionedly by reference to the accompanying drawings the specific embodiment of the present utility model is described; but be not the restriction to the utility model protection domain; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
