Detailed description of the invention
As shown in Figure 1, a kind of vacuum sintering furnace cooling system, comprise for the cool cycles blower fan 3 to sintering furnace 1 interior air-supply, the air outlet of cool cycles blower fan 3 is communicated with the air inlet of sintering furnace 1, the air outlet of sintering furnace 1 is communicated with formation closed loop air channel with the air inlet of cool cycles blower fan 3, pipeline between described sintering furnace 1 air outlet and the air inlet of cool cycles blower fan 3 is provided with cooler 2, described cooler 2 is heat exchange cooling coil, the water inlet of described cooler 2 is communicated with cooling water inlet pipe 7, described cooling water inlet pipe 7 comprises the main water inlet tube 6 and the auxiliary water inlet pipe 8 that are connected in parallel to each other and arrange, the caliber of described main water inlet tube 6 is greater than the caliber of auxiliary water inlet pipe 8, described main water inlet tube 6 is provided with magnetic valve 5.
On described main water inlet tube 6, be also provided with booster pump 11.
The water inlet of described cooler 2 is provided with electro connecting pressure gauge 10.
Described auxiliary water inlet pipe 8 is provided with check valve 12.
As shown in Figure 2, the utility model also comprises for controlling booster pump 11 and the simultaneously opening/closing auxiliary reclay KM1 of magnetic valve 5, the switching signal control that described auxiliary reclay KM1 is exported by PLC is opening/closing, described auxiliary reclay KM1 also controls a time relay KT1 makes it to follow booster pump 11 and magnetic valve 5 simultaneously opening/closing, described time relay KT1 the opening/closing of co-controlling cool cycles blower fan 3 of connecting with electro connecting pressure gauge 10.
Control procedure of the present utility model is as follows:
In the time that cooling system is not worked, on cooling water inlet main pipeline, magnetic valve 5 must not be electric, and in dissengaged positions, booster pump 11 must not be electric, and main water inlet tube 6 does not supply water, and reduces flow, saves the energy.While work due to sintering furnace 1, in a hot environment, if cooler 2 can cause damage to part components and parts in the state of cutting off the water supply for a long time, for preventing because of sintering furnace 1 impact on cooler 2 when the high temperature, and establish auxiliary water inlet pipe 8.Auxiliary water inlet pipe 8, always in on-state, ensures that cooler 2 is all the time in there being a small amount of flow of cooling water state, thereby cooler 2 is protected, but caliber low discharge is little, and the little energy consumption of water consumption is also few.A booster pump 11 is installed on main water inlet tube 6, is produced instantaneous pressure pulse, can rinse the incrustation scale in cooler 2 better, strengthen heat exchange efficiency.A check valve 12 is installed on auxiliary water inlet pipe 8, to prevent that cooling water from refluxing.
In the time that production work flow process arrives process for cooling, PLC control signal K closure, auxiliary reclay KM1 connects, the KM1 closure of often making war, the relay switch KM2 of magnetic valve 5 obtains electric, magnetic valve 5 conductings, booster pump 11 obtains electric, main water inlet tube 6 is opened, and booster pump 11 pressurized water supplies strengthen hydraulic pressure flow, produce momentary pulse current simultaneously cooler 2 is carried out to flush clean.Another road time relay KT1 obtains electric.Cool cycles blower fan 3 starts needs to meet two conditions, one is magnetic valve 5 conductings, main water inlet tube 6 is connected and is supplied water, when pipeline pressure rises to setting value, the normal closure of making war of electro connecting pressure gauge 10, second condition is because cooling water enters in full amount cooler 2 and needs time course, so install time relay KT1 additional, KT1 closure after time relay time delay, ensure that cooler 2 has enough cooling waters to enter circulation, prevent that high-temperature gas from entering the cooler 2 of few water, cause dry combustion method, thereby cause equipment breakdown and production accident.When after the contact switch P and time relay KT1 while closure of electro connecting pressure gauge 10, the 3 startup work of cool cycles blower fan, complete after cooling task, and PLC switching signal K disconnects, and road resets completely.
The utlity model has following advantage:
Use magnetic valve 5 to control main water inlet tube 6, only carry out when cooling, just making magnetic valve 5 open at sintering furnace, the product in burner hearth is carried out cooling, all the other periods are closed condition, thereby the system energy obtains maximized saving.
Set up booster pump 11 booster pump pressurized water supplies and strengthen hydraulic pressure flow, while startup, produce momentary pulse current simultaneously cooler 2 inwalls are carried out to flush clean.Reduce incrustation scale and increase heat exchange efficiency, could bring into play better cooling effect.A check valve 12 to be installed on auxiliary water inlet pipe 8 and prevent that cooling water from refluxing.
Install auxiliary water inlet pipe 6 additional cooler 2 is remained to low discharge supplies water, take away the heat passing over when sintering furnace 1 heats, cooler 2 is protected.
When magnetic valve 5 is opened, after booster pump 11 starts, on circuit after time relay time delay, and in the time that electro connecting pressure gauge 10 detects that hydraulic pressure reaches setting value, restart cool cycles blower fan 3, in order to avoid high-temperature gas heats when the low output cooler 2, damage cooler 2.
