Abstract
The utility model relates to a control circuit of a bag type dust collector combined with an ash cleaning device. The control circuit comprises k pulse electromagnetic valves, n pulse controllers and at least 4n PLC (Programmable Logic Controller) control points. The 4n PLC control points correspond to the k pulse electromagnetic valves through the n pulse controllers. According to the control circuit provided by the utility model, the number of the PLC control points can be saved, the use level of cables can be reduced, and the cost can be lowered; the automated control level is improved; ash cleaning control on any bag type dust collectors can be realized and the forms of the dust collectors are not limited.
Description
Technical field
The utility model relates to a kind of sack cleaner combination deashing device control circuit.
Background technology
Sack cleaner is also referred to as filtration dust catcher, is a kind of dry type high efficiency deduster, and the bag type filtering element that it utilizes fibrous braid to make captures solid particulate matter in the dusty gas.Its action principle is that grit is blocked because of the collision of inertia force effect and fiber when walking around fiber cloth, trickle grit (particle diameter is 1Lm or less) then is subjected to gas molecular impingement (Brownian movement) constantly changing the direction of motion, because interfibrous space is less than the free path of gas molecule Brownian movement, grit is convenient to fiber collision contact and is separated.Diffusion, the inertia of the weaving method of its course of work and filtrate, the density of fiber and dust, block, the factor such as gravity and electrostatic interaction and ash removal method be relevant.
At present, need to use a large amount of impulse electromagnetic valves in the pulsed sack cleaner, as shown in Figure 1, in the deashing control circuit of existing impulse electromagnetic valve, the control of paired pulses magnetic valve all is to adopt one to one control mode, and each impulse electromagnetic valve is controlled by a PLC control point, separately separately control, like this, just need to use a large amount of PLC control point and cable, holistic cost is higher.
Summary of the invention
The purpose of this utility model provides a kind of sack cleaner combination deashing device control circuit.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of sack cleaner combination deashing device control circuit comprises k impulse electromagnetic valve, a n pulse control instrument and 4n PLC control point at least, and 4n described PLC control point is by the individual described impulse electromagnetic valve of the individual described pulse control instrument correspondence k of n.
Preferably, the quantity of described impulse electromagnetic valve is 200, the quantity of described pulse control instrument is 10, and the quantity at described PCL control point is 40, and 4 described PLC control points are by 1 corresponding 20 described impulse electromagnetic valve of described pulse control instrument.
Preferably, described pulse control instrument is 20 gate pulse controllers.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1, saves PLC control and count, reduce the consumption of cable, reduce cost;
2, improved automatic control level;
3, can realize the deashing control of any sack cleaner, to the not restriction of deduster form.
Description of drawings
Fig. 1 is the circuit theory diagrams of the deashing control circuit of PLC in the prior art;
Fig. 2 is the circuit theory diagrams of the sack cleaner combination deashing device control circuit in the utility model.
Wherein: 1, PLC control point; 2, pulse control instrument; 3, impulse electromagnetic valve.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
As shown in Figure 2: work as n=10, the quantity of impulse electromagnetic valve 3 is 200, and the quantity of pulse control instrument 2 is 10, and the quantity at PLC control point 1 is 40(4n) individual, wherein pulse control instrument 2 can adopt 20 gate pulse controllers.1 pulse control instrument 2 can be controlled 20 impulse electromagnetic valves, 3,1 pulse control instruments 2 needs 4 PLC control points 1, that is to say 4 PLC control points 1 of 3 needs of 20 impulse electromagnetic valves.
PLC control point 1 is J11, J12, J13, J14, J21, J22, J23, J24 among the figure ... J101, J102, J103, J104 ... Jn1, Jn2, Jn3, Jn4 also reduce the consumption of cable when reduce at PLC control point 1.
Saving the percentage that PLC control counts in the present embodiment is:, k=200 wherein, n=10, saving percentage is 80%.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed within the protection domain of the present utility model.
