Description

Technical Field

[0001] The utility model relates to the field of dairy product production, in particular to an anti-blocking hot water automatic supply device. Background Art

[0002] Currently, dairy production lines require regular cleaning of fermentation tanks, storage tanks, and other tanks used in production. This is typically done by pumping high-pressure water directly into the tanks to clean and disinfect them. However, the existing cleaning process typically involves heating tap water first and then pumping the heated water directly into the water guns. This process creates scale that can easily clog pipes. Furthermore, if the water supply is insufficient during the cleaning process, not only does it affect cleaning efficiency, but the hot water loses heat quickly, preventing effective cleaning when it is pumped into the tanks. Utility Model Content

[0003] The purpose of the utility model is to prevent impurities from entering the cleaning pipe during the heating process, and at the same time realize automatic replenishment, thereby reducing the heat loss of hot water and always keeping the cleaning water at a specific temperature.

[0004] The utility model adopts the following technical solutions:

[0006] Preferably, the heating tank is also connected to an external water pump through a cold water pipe.

[0007] Preferably, positioning holes are provided on the edges of the first flange and the second flange, and a moisture-proof seat is also provided on the bottom of the water storage tank.

[0008] Preferably, an electric heating tube is spirally installed inside the heating tank, and an electric heating controller is also provided on the upper part of the heating tank, and the electric heating controller is connected to the electric heating tube.

[0009] Preferably, a monitoring unit is provided inside the contact sleeve, and the monitoring unit is located above the top rod. A sealing ring is also provided on the upper edge of the hot water inlet pipe.

[0010] Preferably, a contact spring is further provided on the upper portion of the push rod, and the contact spring is located below the monitoring unit.

[0011] Preferably, a solenoid valve is further provided on the hot water outlet pipe, and the diameter of the hot water outlet pipe is smaller than the diameter of the hot water inlet pipe, and the solenoid valve is electrically connected to the monitoring unit.

[0012] Preferably, a temperature detector and a drain pipe are also provided on the water tank, and one end of the temperature detector extends into the water tank, and the drain pipe is connected to the bottom of the water tank.

[0013] Principle of this utility model:

[0014] The first step is to install the heating pipe on the upper part of the water storage tank, connect the first flange and the second flange together by tightening screws, and directly let normal temperature water enter the heating tank through the cold water pipe through an external water pump. Then, under the action of the electric heating controller, the internal electric heating pipe is heated to heat the cold water. After heating to a certain temperature, the solenoid valve opens, and the hot water reaches the water storage tank through the filter and the hot water inlet pipe. The water storage tank sends constant temperature water to the high-pressure water gun through the water pump. When the water tank is filled with hot water, the contact spring on the top rod contacts the monitoring unit. When the hot water inside the water storage tank decreases, the water level monitoring float moves downward under the action of gravity, causing the contact spring to disengage from the monitoring unit. The monitoring unit will control the solenoid valve to open and automatically replenish. Once the temperature inside the water storage tank drops, the electric heating controller controls the upper heating tank to continue heating, thereby realizing automatic replenishment of cleaning water and maintaining a constant temperature.

[0015] The beneficial effects of the present invention are:

[0016] The heating tank is installed on top of the water storage tank. The heated water is first filtered through a filter and then stored in the water storage tank. Once the water level in the water storage tank drops, the water level monitoring float transmits the need for replenishment to the monitoring unit, which then controls the solenoid valve to automatically replenish the water. At the same time, when the water temperature drops, the electric heating controller promptly heats the water. This utility model not only achieves automatic water level replenishment, but also maintains a constant water temperature, which is conducive to improving cleaning efficiency.
