Abstract
The utility model relates to a water-inlet pressure differential type excretion machine of an electric boiler, which belongs to the excretion machine of the electric boiler. The excretion machine comprises the electric boiler, an upper water feeder, a lower water feeder, a three-way water separator and a blowing pipe, wherein the upper water feeder and the lower water feeder are arranged on the upper end of the electric boiler, both the upper water feeder and the lower water feeder are connected with a water inlet pipe through the three-way water separator, the blowing pipe is connected on the bottom end of the electric boiler, and the outlet of the blowing pipe is positioned between the water inlets of the upper water feeder and the lower water feeder. Water is injected into the electric boiler through the upper water feeder and the lower water feeder, when the upper water feeder is closed, the boiler normally works, when the upper water feeder is opened, the water level of the upper water feeder is the final water level at last, when the water level of the upper water feeder is higher than the water outlet of the blowing pipe, the blowing pipe begins to discharge water outwards, and simultaneously scale and deposit on the bottom of the boiler are automatically discharged. The utility model has the advantages that the excretion machine has simple and reliable structure, restricting elements, such as valves and the like are not used in the blowing tube of the boiler, the excretion machine is unblocked, and the boiler does not leak.
Description
Technical field
The utility model relates to a kind of excretion machine of electric water-boiling device, particularly a kind of electric water-boiling device differential excretion machine of intaking.
Background technology
As everyone knows, after water was heated, calcium carbonate will be separated out in the water, boiler use the incrustation scale of separating out behind the certain hour in a large number productive set, swim in the boiler so that water outlet muddiness influences effluent characteristics, it is healthy to endanger the drinking-water person.Incrustation scale very easily adsorbs, and will stop up valve when incrustation scale is adsorbed on the valve, and when using magnetic valve to carry out automatic pollution discharge, magnetic valve is very easily stopped up and leaks by incrustation scale, causes automatic pollution discharge to lose efficacy.At present, the boiler that people use all is to adopt artificial blowdown, boiler is as product used in everyday, need manually boiler to be carried out periodic maintenance, periodical blowdown, general personnel are difficult for grasping, and along with the raising of people to the drinking water quality requirement, so the boiler automatic pollution discharge is boiler industry one a big bottleneck.
The utility model content
The purpose of this utility model is to provide a kind of: do not need manually the electric water-boiling device that boiler carries out periodic maintenance, the blowdown differential excretion machine of intaking
The purpose of this utility model is achieved in that this excretion machine comprises electric water-boiling device, enterprising hydrophone, following water inlet device, threeway water knockout drum and blow-off pipe, enterprising hydrophone and following water inlet device are installed in the upper end of electric water-boiling device, enterprising hydrophone all is connected with water inlet pipe by the threeway water knockout drum with following water inlet device, blow-off pipe is connected the bottom of electric water-boiling device, and the outlet of blow-off pipe is between the water inlet of enterprising hydrophone and following water inlet device.
Described threeway water knockout drum is a triple valve; Or threeway.
Described enterprising hydrophone and following water inlet device are respectively water inlet pipe and following water inlet pipe; Perhaps enterprising hydrophone and following water inlet device are ball float automatic control watering machine, are connected with valve on the water inlet of enterprising hydrophone.
Beneficial effect: owing to adopted such scheme, water is by enterprising hydrophone and the water filling in electric water-boiling device of following water inlet device, when closing enterprising hydrophone, water under the device water filling to boiler of intaking, the boiler operate as normal; When opening enterprising hydrophone, enterprising hydrophone and hydrophone water filling in boiler simultaneously when following, the water level of last above water inlet device is last water level, the water level of enterprising hydrophone is higher than the delivery port of blow-off pipe, blow-off pipe begins outside draining, simultaneously the incrustation scale and the old long-pending thing of boiler bottom are discharged, do not need manually boiler to be carried out periodic maintenance, blowdown, reached the purpose of this utility model.Advantage: this excretion machine is simple in structure, reliable, does not use restricting elements such as valve in the blow-off pipe of boiler, and blowdown apparatus does not stop up, and boiler does not leak.
