Description

Technical Field

[0001] This utility model relates to the field of industrial equipment cleaning technology, specifically to an automatic temperature-controlled acid washing water tank device for cleaning equipment. Background Technology

[0002] Chemical cleaning is a commonly used method in the maintenance and repair of industrial and commercial equipment. Analysis of experimental results revealed that the decomposition of calcium-alkali blockages in condenser tube bundles is generally ineffective in room-temperature water-based cleaning agents. The decomposition rate accelerates when the water temperature reaches 30°C, and significantly increases at around 50°C, resulting in better cleaning. However, current cleaning methods have several drawbacks: manual temperature adjustment is time-consuming and labor-intensive, and it's difficult to precisely control the agent temperature within the set range, leading to inconsistent and unstable cleaning results and affecting the overall cleaning quality. Traditional temperature control methods may result in unnecessary energy waste and are not economical in terms of energy utilization. Inappropriate water temperatures can damage water tanks, equipment, and related cleaning equipment, shortening their lifespan and increasing maintenance costs. In scenarios requiring direct contact with cleaning agents, unsuitable temperatures can reduce worker comfort and work experience. To address these issues, a sustainably heated and corrosion-resistant water tank needs to be manufactured to meet the requirement that chemical agents must circulate continuously at a water temperature of 50°C for 6 to 8 hours during equipment cleaning, thereby reducing the labor intensity and operational risks for personnel. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide an automatic temperature-controlled acid washing water tank device for cleaning equipment. This device can automatically control the temperature of the cleaning solution to ensure that the acid washing operation is carried out at a suitable temperature, thereby improving cleaning efficiency and effect, while ensuring operational safety.

[0004] To achieve the aforementioned objectives of this utility model, the technical solution adopted is as follows: An automatic temperature-controlled acid washing water tank device for cleaning equipment includes a movable base, which includes a supporting base plate. Multiple casters are mounted on the bottom of the supporting base plate. A water storage tank, a circulating water pump, and a control box are fixedly mounted on the supporting base plate. At least one electric heating rod is installed on the inner wall of the water storage tank, and a temperature sensor is also installed on the inner wall of the water storage tank. The inlet of the circulating water pump is connected to the water storage tank, and the outlet of the circulating water pump is connected to the equipment to be cleaned via a cleaning fluid inlet pipe. The electric heating rod, temperature sensor, and circulating water pump are electrically connected to the control box. The control box is equipped with a display screen for displaying the set temperature of the electric heating rod, the liquid temperature in the water storage tank, and the operating status of the circulating water pump. The control box also includes a temperature adjustment knob and a water pump switch button.

[0005] As a further improvement of this utility model, two 2KW electric heating rods are symmetrically installed inside the water storage tank. The electric heating rods have a U-shaped structure, which can increase the heating area, improve heating efficiency, and make the water temperature more uniform.

[0006] As a further improvement of this utility model, the water storage tank is made of stainless steel plate, with external dimensions of 700mm×700mm×1000mm and internal volume of 490L.
