Spray pre-treatment groove tank liquor heater
Technical field
It the utility model is related to spraying pre-treatment field, more particularly to a kind of spraying pre-treatment groove tank liquor heater.
Background technology
In pre-processing device, the heater of Phosphating Slot tank liquor is usually plate type heat exchanger, in the device, Phosphating Slot
Heat-shift between tank liquor and hot water is so that tank liquor heats up, and hot water is heated by heater, this mode energy
Consumption is big, and cost is high, and heat transference efficiency is low.
Utility model content
In order to solve the problems of the prior art, the utility model provides a kind of energy-conserving and environment-protective and the high spray of the efficiency of heating surface
Apply pre-treatment groove tank liquor heater.
The utility model provides a kind of spraying pre-treatment groove tank liquor heater, including Phosphating Slot, cistern, baking
Stove, water pump, temperature sensor and controller, in the Phosphating Slot, the Phosphating Slot base fabric is provided with the temperature sensor
Heating tube, the cistern are connected by the water pump and the first communicating pipe with the oven, and the oven passes through second
Communicating pipe connects with described heating tube one end, and the heating tube other end connects with the cistern, the heating tube with it is described
Magnetic valve is additionally provided between second communicating pipe, the magnetic valve, temperature sensor and water pump are electrically connected with the controller.
As further improvement of the utility model, first communicating pipe one end connected with the cistern lower end, institute
State first communicating pipe the other end with it is described baking furnace upper end connect, the water pump was connected on first communicating pipe.
As further improvement of the utility model, second communicating pipe one end connected with the oven lower end, institute
State second communicating pipe the other end connected with described heating tube one end, the heating tube other end connects with the cistern upper end.
As further improvement of the utility model, the oven is provided with water storage cavity, first communicating pipe and described
Second communicating pipe connected with the water storage cavity.
The beneficial effects of the utility model are:Circulating water heating is directly carried out by oven, without heater, energy-saving ring
Protect, and unnecessary warm water can also supply washing room water, the energy is fully used, and passed by controller, temperature
Sensor and magnetic valve can carry out Full-automatic temperature control, more convenient.

Embodiment
As shown in figure 1, the utility model discloses one kind to spray pre-treatment groove tank liquor heater, including Phosphating Slot 1, storage
Pond 2, oven 3, water pump 4, temperature sensor and controller 5, the temperature sensor are described in the Phosphating Slot 1
The base fabric of Phosphating Slot 1 is provided with heating tube, and the cistern 2 is connected by the communicating pipe 7 of water pump 4 and first with the oven 3,
The oven 3 is connected by the second communicating pipe 8 with described heating tube one end, the heating tube other end and the cistern 2
Connection, is additionally provided with magnetic valve 6, magnetic valve 6, temperature sensor and the water between the heating tube and second communicating pipe 8
Pump 4 is electrically connected with the controller 5, and described one end of first communicating pipe 7 connects with the lower end of cistern 2, and described first
Communicating pipe 7, the other end was connected with the upper end of oven 3, and the water pump 4 was connected on first communicating pipe 7, and described second
Communicating pipe 8, one end connected with the lower end of oven 3, and the other end of the second communicating pipe 8 connects with described heating tube one end, institute
The heating tube other end is stated to connect with the upper end of cistern 2.The device is worked by water pump 4, and the water in cistern 2 is passed through into pipe
Road is transported in oven 3 and circulated, and is heated using furnace temperature, and the hot water of output injects the heating tube of the bottom of Phosphating Slot 1 through piping
It is interior, the temperature of tank liquor is controlled by magnetic valve 6 when hot water enters in groove, can be certainly when temperature is higher than the maximum temperature set in groove
Dynamic closing switch, stops supplying hot water, when temperature is less than set minimum temperature, automatically opens up magnetic valve 6 and switch, continue to supply
Hot water, and remaining warm water uses available for employee, because oven 3 is original equipment, can so make full use of baking
The furnace temperature of oven 3, energy-conserving and environment-protective, cost is low, and the efficiency of heating surface is high.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that specific implementation of the present utility model is confined to these explanations.For the ordinary skill of the utility model art
For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be regarded
To belong to the scope of protection of the utility model.
