detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

Example 1

The heating device with steam recovery function, as shown in Figure 1, includes a water tank 1, a balance water tank 4 and a heater 2 connected in sequence through pipelines, the water tank 1 and the balance water tank 4 are connected by a first constant flow pump, and the bottom of the balance water tank 4 passes through The outlet pipe 41 of the balance water tank is connected to the bottom of the heater 2, the water tank 1 is provided with a water tank inlet pipe 11 and a water tank outlet pipe 12, and the water tank inlet pipe 11 and the water tank outlet pipe 12 are respectively provided with a water inlet solenoid valve 13 and a water outlet solenoid valve 14.

It also includes a controller for controlling the operation of the first constant-flow pump. The balance water tank 4 is provided with a liquid level detector connected with the controller and used for detecting the water level in the balance water tank 4 . During operation, the raw water first enters the water tank through the water inlet solenoid valve 13 and the water tank inlet pipe 11. When heating is required, the water in the water tank 1 first enters the balance water tank 4 through the first constant flow pump, and then is balanced The water tank 4 enters the heater 2 to be heated. During this process, the first constant-flow pump keeps working. When the heater 2 fails to heat in time, the water in the balance water tank 4 will gradually increase, resulting in When the water level rises, the liquid level detector in the balance water tank monitors the water level height in real time during the water level rise process and transmits the detected liquid level signal to the controller. When the water level in the balance water tank 4 rises to a certain position, the controller According to the liquid level signal received, the first constant flow pump is controlled to reverse, so that the water in the balance water tank 4 flows back into the water tank to ensure the balance of the water level in the balance water tank 4, thereby realizing the cyclic operation of the entire system and improving the overall work efficiency.

Also includes a condenser 3 fixed inside the water tank 1, the upper end of the condenser 3 is connected to the upper end of the heater 2 through a steam pipe 31, the lower end of the condenser 3 is connected to the water tank 1 through a liquefied water outlet pipe 32, and the liquefied water outlet pipe 32 There is a second constant flow pump 5 on it.

The heater 2 will generate a large amount of steam during the heating process, so in this embodiment, a condenser 3 connected to the upper end of the heater 2 is arranged in the water tank 1, and the steam generated in the heater 2 rises, and when the heater is turned off, Under the premise of the water pipe, the steam in the heater 2 is constantly increasing, and then is pressed into the steam pipe 31, and enters the condenser 3 through the steam pipe 31, and the steam is liquefied and collected in the condenser 3. Since the condenser 3 is made of stainless steel and immersed in water, the heat dissipation effect is good, so the heat released during the liquefaction process of the steam in the condenser 3 can be directly transferred to the raw water in the water tank 1, thereby increasing the temperature of the raw water in the water tank 1 , and the water formed after liquefaction returns to the water tank 1 through the second constant flow pump 5, and through such a cycle, the steam is recycled to heat the temperature of the raw water, so that the raw water heated in the heater 2 is preheated, The heating time is fully saved, and at the same time, the influence of a large amount of steam on the appearance of the equipment is eliminated, so as to achieve the purpose of energy saving.

Example 2

Same as embodiment 1, the difference is that it also includes a timer connected to the controller, the timer is used to calculate the working time of the first constant flow pump and transmits the calculated time signal to the controller, and the controller controls according to the received time signal The first constant flow pump operates. During operation, the raw water first enters the water tank through the water inlet solenoid valve 13 and the water tank inlet pipe 11. When heating is required, the water in the water tank 1 first enters the balance water tank 4 through the first constant flow pump, and then passes through the balance water tank. 4 Enter the heater to heat, when the first constant flow pump works to the set time, the timer sends a time signal to the controller, and the controller controls the first constant flow pump to reverse according to the received time signal, so that the balance The water in the water tank 4 flows back into the water tank 1 to ensure the balance of the water level in the water tank, so that the circulation of the entire system can be realized and the overall work efficiency can be improved.

Example 3

The same as Embodiment 1 or 2, the difference is that when the controller receives any one of the time signal of the timer or the liquid level signal of the liquid level detector, it controls the first constant flow pump to reverse, so that the balance The water in the water tank returns to the water tank to ensure the balance of the water level in the water tank, realize the circulation of the whole system, and improve the overall work efficiency.

In a word, the above descriptions are only preferred embodiments of the present utility model, and all equal changes and modifications made according to the patent scope of the utility model should fall within the scope of the utility model patent.
