The specific embodiment
Structure of the present invention as shown in Figure 2-5, a kind of low temperature season mixing concrete automatic heating device, the water tank 1 that comprises sealing, water tank 1 is provided with manhole and the first stifle 2 and the second stifle 11, overfall 3, sewage draining exit 9 and water tank hanger 4, water inlet 5 is provided with floating ball valve 6, delivery port 7 is provided with Pneumatic butterfly valve 8, sewage draining exit 9 is provided with check valve 10, the first double end electric heating tube 13 and the second double end electric heating tube 14 are placed in water tank 1, in water tank 1, be also provided with temperature sensor 12, the first double end electric heating tube 13, the second double end electric heating tube 14 and temperature sensor 12 are connected with control system.Outside water tank 1, be coated with two- layer warming plate 15,16.
The horizontal installation position of delivery port 7 is higher than 4～6 centimetres of the horizontal installation positions of the first double end electric heating tube 13 and the second double end electric heating tube 14.Can effectively avoid heating tube dry combustion method to cause the damage of heating tube, thereby improve the service life of heating tube.
Sewage draining exit 9 is arranged on the bottom of water tank 1; Overfall 3 is a little more than the horizontal installation site of water inlet 5.
The first double end electric heating tube 13 and the second double end electric heating tube 14 are arranged on the two sides of water tank 1.Two double end electric heating tubes and temperature sensor are all connected by nut and rubber plastic sealing gasket and water tank side plate.
Described control system comprises three-phase ac contactor, temperature controller.
Installation method of the present invention is as follows:
1), install or change workpiece in water tank
First open check valve 10, by the water in sewage draining exit 9 emptying water tanks 1, after open water tank manhole the first stifle 2, then by people, enter water tank 1 inside, in water tank 1 outside, there is special messenger's compounding practice, install successively or change floating ball valve 6, temperature sensor 12, the first double end electric heating tube 13 and the second double end electric heating tube 14.
2), connect water tank and import and export pipeline
3), connect heating tube power supply
By the first double end electric heating tube 13 and the second double end electric heating tube 14 and temperature sensor 12 and control system connection, every double end heating tube all adopts the connection in parallel of 380V power supply.Control system comprises three-phase ac contactor, temperature controller, temperature controller receives the signal of temperature sensor 12, according to setting value, control the break-make of three-phase ac contactor, to give the first double end electric heating tube 13 and the second double end electric heating tube 14 energising or power-off, thereby reach the object of controlling the water temperature in water tank 1.
Operation principle of the present invention is as follows:
As shown in Figures 1 and 2, come from the water of water supply line when water inlet 5 enters water tank to normal working water level, floating ball valve 6 is closed automatically.Set the heating-up temperature value of water in water tank 1, start heating automatic control system, water tank Automatic-heating.When the water in water tank 1 reaches set temperature value, the first double end electric heating tube 13 and the second double end electric heating tube 14 stop heating automatically.When batching plant starts mixing concrete, operator is when starting and opening delivery port Pneumatic butterfly valve 8, hot water in water tank 1, from delivery port 7 flows into scale hoopers and weighs, then enters batching plant mixing drum mixing concrete, to realize the object that improves batching plant outlet temperature.Now, when the water level in water tank 1 starts to decline, the floating ball valve 6 on water inlet is opened automatically, water tank 1 starts supplementing water, when the water level in water tank 1 rises to normal working water level, floating ball valve 6 is closed water inlet 5 automatically, and the water level in water tank 1 keeps normal working water level.Because water tank 1 is in the process of water-filling, the temperature of water declines simultaneously, double end heating tube 13 and 14 Automatic-heatings, and when the temperature of water reaches setting value, the first double end electric heating tube 13 and the second double end electric heating tube 14 are closed automatically.
