Description

An automatic water level regulating device for a heat exchange station water tank Technical Field

[0001] This utility model relates to the technical field of water tanks in heat exchange stations, and in particular to an automatic liquid level adjustment device for water tanks in heat exchange stations. Background Technology

[0002] A heating station is a place where heat is concentrated and exchanged. Based on the heating method, they are divided into direct-supply stations and indirect-supply stations. The former, where power plants directly supply users, results in high temperatures, is difficult to control, and wastes heat energy. It originated from the initial welfare heating provided by power plant waste heat. With the development of the commodity economy and the commodification of heat, heating companies began to improve the quality of heating, leading to indirect-supply stations, which fall under the category of centralized heating. There is also boiler heating, which eliminates the power plant step, but it is inefficient, highly polluting, and is nearing obsolescence. Centralized heating is the future direction, with indirect-supply stations becoming the mainstay.

[0003] The existing Chinese utility model patent with application number CN202221467272.9 relates to an automatic control device for the liquid level of a water tank in a heat exchange station, including a fixed pole, a side fixing block, a top fixing box, a transmission screw, a bottom clamping block, and a top fixing block, which can make the water tank more intelligent.

[0004] However, the aforementioned device does not have the ability to clean its own internal sediment, nor does it have the ability to actively adjust the liquid level. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides an automatic water level adjustment device for heat exchange station water tanks, which collects sediment in the water tank through a sludge collection device, facilitates the discharge of sediment at the bottom of the water tank, monitors the water level in the water tank through an auxiliary device, and facilitates the adjustment of the water level in the water tank through a control device, thereby improving the practicality of the device.

[0006] This utility model discloses an automatic liquid level adjustment device for a heat exchange station water tank; it includes a sludge collection device, an auxiliary device, and a control device. The auxiliary device is installed on the sludge collection device, and the control device is installed on the sludge collection device. The sludge collection device collects sediment in the water tank and facilitates the discharge of sediment at the bottom of the water tank. The auxiliary device monitors the water level in the water tank, and the control device facilitates the adjustment of the liquid level in the water tank, thereby improving the practicality of the device.

[0007] Preferably, the sludge collection device includes a water tank, a sloping bottom, a sludge collection trough, an extension pipe, a plate-type solenoid valve, spiral blades, and a geared motor. The water tank has a sloping bottom, with a sludge collection trough located in the middle of the bottom of the sloping bottom. An extension pipe is installed at the bottom right end of the water tank, connecting to the sludge collection trough. A plate-type solenoid valve is installed at the output end of the extension pipe. Spiral blades are installed in the sludge collection trough, extending into the extension pipe. A geared motor is installed at the lower left end of the water tank, with its output end connected to the spiral blades. The sloping bottom of the water tank facilitates the collection of sediment in the water, allowing the sediment to slide into the sludge collection trough. Activating the geared motor transmits power to the spiral blades, causing them to rotate. The rotating spiral blades push the sediment in the sludge collection trough into the extension pipe and compress it. The plate-type solenoid valve is periodically opened to discharge the sediment, reducing the operator's workload and improving the device's practicality.

[0008] Preferably, the auxiliary device includes a connecting pipe, a filter screen, and a liquid level sensor. The connecting pipe is installed on the front face of the water tank, and its upper and lower parts are connected to the upper and lower parts of the water tank, respectively. A liquid level sensor is installed on the upper part of the connecting pipe, and the sensing end of the liquid level sensor extends to the bottom of the connecting pipe. A filter screen is installed at the port connecting the connecting pipe and the water tank. The liquid entering the connecting pipe is filtered through the connecting pipe, reducing the impact of impurities and sediments in the water on the sensing end of the liquid level sensor. The liquid level sensor monitors the water level, improving the practicality of the device.

[0009] Preferably, the control device includes an inlet pipe, an outlet pipe, solenoid valves, a display, and an operation panel. The inlet pipe is installed on the upper left side of the water tank, and a set of solenoid valves is installed on the inlet pipe. The outlet pipe is installed on the lower right side of the water tank, and a set of solenoid valves is installed on the outlet pipe.

[0010] Preferably, the device also includes a support frame, a cross-shaped fixing frame, and a vibration motor. A set of vibration motors is installed on the lower part of the front face of the water tank via the support frame. The rear face of the support frame is connected to the lower part of the connecting pipe via a connecting rod. A cross-shaped fixing frame is provided on the filter screen. When the vibration motor is turned on, the power is transmitted to the filter screen at the bottom of the connecting pipe via the connecting rod, causing the filter screen to vibrate, thereby reducing the amount of sediment adhering to the filter screen. The cross-shaped fixing frame increases the structural strength of the filter screen, improving the practicality and stability of the device.

[0011] Preferably, it also includes a storage battery, which is installed in the middle of the right end face of the water tank; the storage battery provides temporary power to the electrical appliances of the equipment, reducing the impact of power outages on the normal operation of the equipment and improving the practicality of the device.
