Description

Technical Field

[0001] The utility model relates to the technical field of waterproof coiled material production, in particular to a waterproof coiled material asphalt pool with adjustable heating flow. Background Art

[0002] Usually, during the production of waterproof membranes, asphalt needs to be coated on the raw base fabric, and the asphalt is added to the asphalt pool. The base fabric passes through the asphalt pool during the transfer process, so that the asphalt is coated on the base fabric. The asphalt in the asphalt pool is liquid, and the asphalt in the asphalt pool needs to be kept at liquid temperature to avoid asphalt agglomeration. At this time, it is necessary to add heated heating oil to the heating and insulation layer in the asphalt pool to heat and insulate the asphalt in the asphalt pool, so that the asphalt in the asphalt pool can be kept at the corresponding temperature for a long time, and the asphalt can be better coated on the base fabric.

[0003] However, when heating oil is added to the insulation layer of existing asphalt pools, it is heated independently. This means that the heat transfer oil in the insulation layer of each asphalt pool is heated independently, preventing centralized heating of multiple asphalt pools. This results in high energy consumption. Furthermore, the flow rate of the heat transfer oil cannot be controlled, typically requiring intermittent heating and oil circulation without the ability to adjust the flow rate. This can result in the asphalt in the pool being too hot or too cold. Utility Model Content

According to the thermocouple feedback signal, the opening and closing angle of the flow control valve is controlled in real time, and the temperature is accurately controlled within the set numerical range, avoiding the traditional manual opening and closing of the valve, improving control accuracy and saving manpower.

In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] like Figure 1 and Figure 2 As shown, the utility model provides a waterproof coiled material asphalt pool with adjustable heating flow, comprising a heating oil tank 21, a main pipe 22, a branch pipe 23 and an asphalt pool 10;

[0020] The asphalt pool 10 has a heating and insulation layer 11, which is a coil structure (not shown in the drawings); the coil structure is, for example, an existing serpentine-arranged pipe structure, which is evenly arranged in the heating and insulation layer for the circulation of heat transfer oil.

[0021] The heating oil tank 21 has an inlet at its upper end and an outlet at its lower end, which is connected to the main pipe 22. Branch pipes 23 are radially disposed along the main pipe 22, the inner ends of which are connected to the heating and insulation layer 11. Each branch pipe 23 is equipped with an electric flow control valve 40. Multiple branch pipes 23 can be arranged on the main pipe 22, each of which can be connected to a group of asphalt tanks 10 to supply heated thermal oil.

[0022] During the operation, the heating oil in the heating oil tank 21 is introduced into the heating and insulation layer 11 (coil structure) of the asphalt pool 10 through the branch pipe 23. Through the action of the coil structure, the asphalt pool 10 can be heated evenly and the electric flow regulating valve 40 on the branch pipe 23 is used.

[0023] Preferably, a thermocouple temperature sensor is installed in the asphalt pool 10 to monitor the temperature, thereby controlling the opening and closing degree of the electric flow regulating valve 40 in real time, and accurately controlling the temperature within the set value range, avoiding traditional manual opening and closing of the valve, improving control accuracy, and saving manpower.

[0025] When the heating oil in the heating insulation layer 11 needs to flow back to the heating oil tank 21 for reheating, the flow regulating valve 33 controls the flow of the heating oil flowing out of the coil structure in the heating insulation layer 11, and then through the action of the suction pump 34, the heating oil enters the reflux main pipe 32 from multiple reflux branches 31, and then flows back to the heating oil tank 21 from the L-shaped pipe 35 for reheating.

Only a portion of the insulation member 50 is shown in the figure, and the insulation member preferably covers the entire extension length of the main pipe 22.
