Description
Technical Field
The invention belongs to the field of hot water supply of ships, and particularly relates to an automatic descaling hot water tank with an inner wall capable of preventing scratches for ships.
Background
With the increasing requirements on the intellectualization and the emission of ships, the use of the electric water heating cabinet for ships is more and more popular. Due to the large hot water demand of the ship and the high heating power, the marine electric water heating cabinet generally has serious scaling. Especially, after the structure of the electric heating pipe, the burning and melting phenomena are easy to generate, and the heating pipe is grounded due to water leakage and cannot be used. After the water temperature rises, scale is easily formed on the inner surface of the water tank, so that the use of the water tank is influenced, and the water quality is influenced. Especially, the seawater contains high content of mineral substances and salts, and the seawater contains a plurality of salts, and sodium chloride, magnesium sulfate, calcium bicarbonate and the like are arranged according to the content. But the main components of the scale are calcium carbonate, magnesium hydroxide and calcium sulfate. These substances have low solubility and decrease with increasing temperature, so that scale is easily formed when seawater is heated, particularly when seawater is concentrated on a heating surface due to the formation of steam bubbles.
People use chemical methods to remove scale for convenience when removing the scale, but when the scale is serious, the chemical methods can not completely remove the scale, and the generated secondary chemicals can pollute the scale.
The utility model discloses a 201721150700.4 discloses a boats and ships hot-water tank, including water tank and controller, be equipped with inlet tube and outlet pipe on the water tank, be equipped with electric heater in the water tank, electric heater is cylindricly, is equipped with a push pedal in the water tank to be equipped with-the cylinder body outside the water tank, the telescopic link of cylinder body links to each other with the push pedal is fixed, and the edge of push pedal is inconsistent with the inner wall of water tank, is equipped with the sliding sleeve of built-in sealing washer in the push pedal, and electric heater runs through the sliding sleeve and slides with the push pedal and links to. The utility model discloses a boats and ships hot-water tank drives the push pedal through the driving cylinder and reciprocates in the water tank, utilizes the friction that produces between the edge of push pedal and the inner wall of water tank, will adhere to incrustation scale and clear away on the inner wall of water tank to avoid the incrustation scale on the water tank at follow-up heating process, absorb the heat that electric heater produced, influence water tank rate of heating and heating efficiency.
Utility model 201721653787.7 discloses a scale deposit prevention water tank for water supply equipment, which comprises a tank body, a water inlet pipe connected with the tank body and a water outlet pipe arranged at the lower part of the tank body, wherein the tank body is cylindrical, a descaling device is arranged in the tank body, the descaling device comprises a rotating shaft and a scraper connected with the rotating shaft, the rotating shaft and the scraper are all vertically arranged, the number of the scrapers is 3, the rotating shaft is used as a central shaft, an angle of 120 degrees is formed between adjacent scrapers, the side wall of the scraper far away from the rotating shaft is bonded with a cleaning flannelette contacting with the inner wall of the tank body, and the rotating shaft is rotatably; the water inlet pipe is horizontally arranged so that the water outlet direction points to the scraper plate; an adsorption felt layer is arranged in the box body and is positioned below the horizontal plane of the water outlet pipe.
The utility model discloses an at the during operation, because rivers themselves have certain water pressure, consequently, the rivers that get into the water tank can strike one of them scraper blade to drive the pivot by this scraper blade and rotate, thereby make two other scraper blades follow the rotation, the scraper blade is rotating the in-process, scrapes down through the incrustation scale that clean cotton flannel formed on with the box inner wall, and the incrustation scale falls behind to be adsorbed by the adsorption felt layer, avoids getting into the outlet pipe. Because be 120 jiaos between the adjacent scraper blade, consequently, no matter how the pivot rotates, will have a scraper blade all the time and can be strikeed by the rivers of intaking, that is to say, as long as the water tank keeps intaking, the scraper blade will work, and the water that gets into the water tank then can form the whirl, and the water level in the water tank risees for after the rivers of intaking are obstructed, the whirl can assist and drive the scraper blade work, makes the box inner wall keep clean.
The patent a boats and ships hot-water tank, the incrustation scale is clear away to the mode of push-and-pull about using, the incrustation scale is clear away incompletely to the incrustation scale, patent 201721653787.7 is to the problem that prior art exists, use rotatory mode to clear away the incrustation scale, the rotation scraper blade of syntropy, and set up the cotton flannel between scraper blade and inner wall, it is inseparable to make scraper blade and inner wall contact, can not thoroughly effectually clear away the incrustation scale, and the power that relies on the providing of rivers makes the scraper blade rotate, under the full water state, the incrustation scale can not in time.
In the device that clears up the incrustation scale that has now, only study to the problem of incrustation scale clearance, do not have to the research to the aspect of the inner wall protection that carries out the clearance water tank box at incrustation scale clearance in-process, and at water tank clearance in-process, if cause the mar of inner wall because the clearance to the water tank, lead to the incrustation scale to hide in the mar of inner wall, make the incrustation scale more difficult to clear up, perhaps thorough inadequately to the clearance of incrustation scale.
