Description
Technical field
The utility model relates to the grate-cooler that a kind of cement producing line is used, and a kind of cement producing line is with the grate-cooler of grate transporting velocity device for automatically regulating specifically.
Background technology
Grate-cooler is mainly comprised of upper shell, lower house, grate, grate transmission device, grate supporting arrangement, chamotte crusher, leakage material machine for zipper, automatic lubrication installation and cooling air unit etc.Grate-cooler is the key equipment of manufacture of cement, at grog, enter after kiln, first through burner, grog is sprayed to calcining, in grate below clinker after firing falls into, by hydraulic transmission, carry out reciprocating conveying, in course of conveying, to hot grog be lowered the temperature by being arranged on the air-cooler of body below, generally, the high temperature chamotte temperature that has just fallen into grate can reach 1300 ℃ of left and right, through the blowing cooling of course of conveying, be delivered to tail end and should be down to 65 ℃+environment temperature left and right, but in actual production process, owing to falling into the high temperature chamotte knot grain size of grate after calcining, thickness and weight cannot be guaranteed uniformity, grate transporting velocity can not corresponding in good time adjustment, can not reach balanced cooling and improve heat recovery efficiency, also cannot guarantee product quality.
It is to set grate speed according to grate pushing arm hydraulic feedback that tradition is adjusted grate transporting velocity, and accurately the anticipation bed of material changes, grog knot grain size.Easily cause following some:
(1) in the constant situation of cooling blower frequency, because kilneye blanking is inhomogeneous or knot grain hour, grate pushes away speed under Artificial Control, and in the time of can not according to circumstances changing in time, grate material loading bed thickness is deep mixed, and grate is directly blown and worn, and does not reach the stable heat radiation of ripe grain.Cause in grate-cooler outlet, grog is because of the inhomogeneous more uncooled red grog that caused that dispels the heat.
(2) grate pushes away speed under Artificial Control, may be too quickly because of supplied materials, and grate pushes away the given not change of speed, and in grate, grog is heaped, and grate flowing resistance is large, cooling bad.Easily cause " making a snowman " (grog dissipation of heat not, form bulk), when serious, will stop kiln and destroy bulk, to production, bring economic loss.
(3) grog, in effectively quenching of grate-cooler, causes ripe fragility poor.Causing cement grinding mill to be unfavorable for milling yields poorly.
(4) grate-cooler rate of heat dissipation is low, kiln secondary, tertiary air temperature also low (secondary, tertiary air temperature be all by high-temperature blower by heat in grate-cooler draw back kiln, preheater secondary utilizes), unfavorable coal dust completing combustion and coal consumption improve.
summary of the invention
The grate transporting velocity that the purpose of this utility model is effectively to solve above-mentioned existence can not adapt to the in good time adjustment problem of actual production, and mud production line Cooler Bed Driving transporting velocity device for automatically regulating is provided.
The utility model is mainly by body (1), hydraulic oil unit (2), grate (3), grate hydraulic transmission (4), grate supporting arrangement, chamotte crusher, leak material machine for zipper, automatic lubrication installation and cooling air unit form, it is characterized in that it also has grate transporting velocity device for automatically regulating, grate transporting velocity device for automatically regulating consists of pressure sensor (5) and automatic regulating system (6), pressure sensor (5) is installed grate (3) below, pressure sensor (3) is electrically connected to the signal input part of automatic regulating system (6), the signal output part of automatic regulating system (6) is electrically connected to hydraulic oil unit (2).
Automatic regulating system (6) is the PID controller of PLC automatic regulating system, computer automatic regulating system or Siemens PCS7.
Pressure sensor (5) is arranged on the air outlet slit place of the air pressure chamber (7) of grate (3) below.
The utility model advantage is:
Material knot grain size on grate-cooler castor bed, thickness can cause that with varying in weight under grate, air pressure chamber pressure changes, the utility model is due to several pressure sensors being set below grate, pressure sensor can import air pressure chamber force value real time data under grate into PLC automatic regulating system in good time, PLC automatic regulating system can be automatically according to the variation of the lower air pressure chamber force value of combing, transmission speed to hydraulic transmission regulates and controls, thereby changing grate reciprocating frequency makes the bed of material reach even, make the cold wind function of below completely balancedly reduce in time hot clinker temperature, while guaranteeing to be transported to tail end, can reach technique cooling parameter, having solved present grate-cooler can not be according to the material knot grain size on castor bed, thickness and weight are carried out speed adjustment, and cannot guarantee the hard nut to crack existing for many years of product quality.There is the science of setting, cold really reliable, favourable raising, stabilized product quality, the utilization of increase Waste Heat Recovery, reduce the distinguishing feature of system thermal energy consumption.

Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1: the utility model is mainly comprised of body (1), hydraulic oil unit (2), grate (3), grate hydraulic transmission (4), grate supporting arrangement, chamotte crusher, leakage material machine for zipper, automatic lubrication installation and cooling air unit, it is characterized in that it also has grate transporting velocity device for automatically regulating, grate transporting velocity device for automatically regulating consists of the PID controller of pressure sensor (5) and Siemens PCS7, and pressure sensor (5) is installed the air outlet slit place of grate (3) below air pressure chamber (7).Pressure sensor (3) is electrically connected to the signal input part of the PID controller (6) of Siemens PCS7, and the signal output part of the PID controller (6) of Siemens PCS7 is electrically connected to hydraulic oil unit (2).
