Description

Technical Field

[0001] The utility model relates to the technical field of boiler water replenishment, in particular to an automatic water replenishment boiler. Background Art

[0002] A boiler is an energy conversion device. The energy input into the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's lives, or it can be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. During the use of the boiler, the boiler needs to be replenished with water.

[0003] At present, the work of boiler water replenishment is mostly done manually. When the water level of the boiler drops to a level that needs to be replenished, the operator will perform the water replenishment operation. However, this method may sometimes cause the operator to forget to replenish water due to negligence, especially when busy or working for a long time. When this happens, the boiler may be damaged due to overheating, or even cause a greater safety accident.

[0004] During the use of the boiler, various impurities in the water, such as minerals, microorganisms, suspended matter, etc., easily enter the boiler with the flow of water. These impurities will form precipitation in the boiler's superheater, water-cooled wall, economizer and other parts, affecting the normal operation of the boiler and even shortening the service life of the boiler. Utility Model Content

[0005] The purpose of the utility model is to provide an automatic water replenishment boiler to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: an automatic water replenishment boiler, comprising a furnace body and a water replenishment tank, the water replenishment tank is fixedly installed on the upper end of the furnace body, a water inlet pipe is fixedly installed on the upper end of the water replenishment tank, a filter cartridge is rotatably installed in the water replenishment tank, one end of the filter cartridge is connected to a pipeline through rotation, the pipeline is fixedly connected to one end of an induction pump, one end of the induction pump is connected to a water limiter through a water supply pipe, the water limiter is fixedly installed in the furnace body, a float is movably installed in the water limiter, a water outlet pipe is fixedly installed at the bottom of the furnace body, and a plurality of heaters are installed on the inner wall of the furnace body.

[0007] Preferably, a partition is installed at the bottom of the furnace body, a second motor is fixedly installed at the bottom end of the partition, one end of the second motor is connected to a stirring rod through an output shaft, and a plurality of heating wires are installed in the stirring rod.

[0008] Preferably, one end of the filter cartridge is connected to a first motor via an output shaft, and the first motor is fixedly mounted on the water replenishment tank.

[0009] Preferably, brush plates are mounted on both sides of the filter cartridge, and the brush plates are movably mounted on the inner wall of the water replenishment tank.

[0010] Preferably, a positioning block is fixedly installed on one side of the water replenishing tank, and the positioning block is threadedly screwed to fix one end of the brush plate through a limiting screw.

[0011] Preferably, a collecting drawer is movably installed at the bottom end of the water replenishment tank, and a sealing strip is installed at the connection between the collecting drawer and the water replenishment tank.

[0012] Preferably, an observation port is provided on one side of the furnace body, and a high temperature resistant transparent material is installed at the observation port.

[0013] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0014] First, the utility model can add water to the furnace body in time by setting an induction pump and a water limiter. When the water level in the furnace body is low, the float in the water limiter drops, opening the restriction on the water supply pipe. The induction pump detects the decrease in water pressure and starts working, sending the filtered water into the furnace body through the water supply pipe. When the water level rises, the float rises and comes into close contact with the water supply pipe, limiting the water flow. The induction pump detects the increase in water pressure and stops working, thereby replenishing water to the boiler in time, improving work efficiency and reducing the occurrence of safety accidents.

[0015] Second, the utility model can reduce the impurities in the water from entering the furnace body by setting the filter cylinder and the brush plate. The filter cylinder in the water supply tank filters the water to prevent impurities from entering the furnace body, thereby preventing the pipes in the boiler from being blocked and scaling. When there are too many impurities on the filter cylinder, the water supply tank is emptied, and the first motor drives the filter cylinder to rotate, contacting with the brush plate to scrape off the impurities, and the impurities fall into the collection drawer for collection, and the collection drawer is manually taken out to remove the impurities, thereby increasing the service life of the boiler.

[0016] Third, the utility model can quickly replace the brush plate by setting the brush plate and the limit screw, and the brush plate is threadedly connected to the positioning block through the limit screw. When replacing the brush plate, the screw is manually unscrewed, the brush plate is pulled out, the new brush plate is put in, and the screw is manually tightened, thereby improving the work efficiency of replacing the brush plate.
