Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a temperature control and heating device for non-curing materials. Background Technology

[0002] Non-curing materials are widely used in the construction industry, with non-curing rubberized asphalt waterproof coatings being a common example, playing a crucial role in roof waterproofing. Before use, non-curing materials require heating equipment to melt them. Traditional non-curing heating devices work by connecting a power source to a resistance wire, which rapidly heats the material. However, traditional non-curing heating equipment has the following problems: 1) The heating power remains constant while heating the material, and there is no power-off mechanism. Once the material melts, heating continues, posing a fire hazard; 2) Different non-curing materials have different melting points, and traditional heating equipment cannot meet the requirements for temperature regulation; 3) Traditional heating equipment lacks a temperature feedback device, making it impossible to accurately control the heating of the material to the target temperature; 4) Once the material reaches the target temperature, there is no visual display or alert device.

[0003] Therefore, in order to better control the temperature of non-curing materials during construction and avoid safety hazards, a simple, intelligent, and visual temperature control heating device is needed for heating non-curing materials. Summary of the Invention

[0004] Purpose of the invention: The purpose of this invention is to address the shortcomings of existing technologies by providing a temperature control and heating device for non-curing materials. This device allows for better adjustment and monitoring of the heating temperature during the construction of non-curing materials, ensuring a constant heating temperature, preventing overheating or uneven heating, and reducing the probability of safety hazards.

[0005] Technical Solution: The present invention discloses a temperature-controlled heating device for non-curing materials, comprising a main structure, a heating system, and an adjustment feedback system. The main structure is located in the middle of the heating system and is fixedly connected to the heating system. The adjustment feedback system dynamically adjusts the heating temperature of the heating system based on the actual temperature feedback from uniformly distributed sensors. The main structure includes a vertically arranged T-shaped steel pipe, the bottom of which is fixedly connected to a cross-shaped steel pipe. Both the T-shaped and cross-shaped steel pipes are hollow structures. The heating system includes a cylindrical rotating heating tube surrounding the main structure. One end of the rotating heating tube is connected to a heating wire, and the other end of the heating wire extends upward from the bottom of the T-shaped steel pipe along the hollow structure to the top of the T-shaped steel pipe, and is connected to an explosion-proof connector.

[0006] In this invention, the vertical T-shaped steel pipe and the bottom cross-shaped steel pipe form a rigid hollow frame, which serves as both a supporting structure and a cable channel. The hollow design allows the heating wire to pass through the bottom cross-shaped steel pipe and extend upwards along the inside of the T-shaped steel pipe, achieving fully concealed wiring. The cylindrical rotating heating tube surrounds the main structure, forming a ring-shaped radiant heat source. The current path is: explosion-proof plug (top) → heating wire (inside the steel pipe) → rotating heating tube (bottom periphery).

[0007] Furthermore, the rotating heating tube is composed of a set of annular heating tubes connected sequentially from top to bottom; multiple annular heating tubes are connected in series in the vertical direction to form a gradient heat source in the vertical direction. When rotating, a spiral upward hot airflow is generated, which enhances the heat transfer efficiency from bottom to top.

[0008] Furthermore, a drive motor is connected to the outside of the cross-shaped steel pipe. The drive motor drives the cross-shaped steel pipe to rotate, thereby driving the rotary heating tube to rotate. The 360° rotation of the rotary heating tube allows heat to be evenly radiated to the surface of the non-cured material, avoiding local curing or clumping caused by static heating.

[0009] Furthermore, the adjustment feedback system includes a temperature sensor located at the center of the cross-shaped steel pipe. The temperature sensor is connected to a temperature feedback module via a wire. The temperature feedback module is fixed to the upper part of the T-shaped steel pipe. The temperature feedback module is connected to a temperature regulator fixed to the outer wall of the T-shaped steel pipe via a wire. The temperature feedback module can read the temperature sensor and is connected to the temperature regulator via a wire. The temperature regulator can set the target temperature via a switch and temperature adjustment button on the panel. The temperature regulator and the temperature feedback module form a dynamic linkage.

[0010] A temperature sensor is installed at the center of the cross-shaped steel tube to monitor the temperature of the heating area in real time and convert the physical signal into an electrical signal. The temperature feedback module receives the sensor signal, filters, amplifies, and performs AD conversion to generate a digital temperature value. After the temperature regulator sets the target temperature, the feedback module continuously compares the actual value with the target value, generating an error signal (such as the output of a PID algorithm). This error signal is then used to adjust the heating element power via PWM or analog output. The temperature regulator dynamically adjusts the current or voltage of the rotating heating element based on the error signal, achieving real-time power modulation.

[0011] Furthermore, the explosion-proof joint is a rotary joint with an integrated conductive slip ring structure, which achieves this function through a central conductive layer, an outer sealing cavity, and an explosion-proof shell.

[0012] Beneficial effects: Compared with the prior art, the advantages of the present invention are as follows:

[0013] (1) The cylindrical rotating heating tube and the annular layout in this invention realize omnidirectional synchronous radiation heating, eliminate the temperature gradient of traditional unilateral heating, and are especially suitable for the heat-sensitive characteristics of non-curing materials such as asphalt and adhesives. (2) The hollow steel pipe in this invention not only serves as a load-bearing frame to support the entire device, but also serves as a cable channel to protect the wires and prevent external mechanical damage or high-temperature aging.

[0014] (3) The adjustment feedback system in this invention can correct the output in real time according to the actual temperature of the material. Attached Figure Description

[0018] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the embodiments described.

[0019] like Figure 1 The temperature control and heating device for non-curing materials shown can better adjust and observe the heating temperature during the construction of non-curing materials, ensuring a constant heating temperature, preventing overheating or uneven heating, reducing the probability of safety hazards, and meeting the requirements of green construction. This invention provides a temperature control and heating device for non-curing materials, comprising a main structure, a heating system, and an adjustment feedback system. The main structure includes a vertically arranged T-shaped steel pipe 1-1, the bottom of which is fixedly connected to a cross-shaped steel pipe 1-2. Both the T-shaped steel pipe 1-1 and the cross-shaped steel pipe 1-2 are hollow structures. A drive motor is externally connected to the cross-shaped steel pipe 1-2, which drives the cross-shaped steel pipe 1-2 to rotate, thereby driving the rotating heating tube 2-3 to rotate.

[0020] The heating system includes a cylindrical rotating heating tube 2-3 surrounding the main structure. The rotating heating tube 2-3 is composed of a set of annular heating tubes connected sequentially from top to bottom. One end of the rotating heating tube 2-3 is connected to a heating wire 2-2. The other end of the heating wire 2-2 extends upward from the bottom of the T-shaped steel pipe 1-1 along the hollow structure to the top of the T-shaped steel pipe 1-1, and connects to the explosion-proof connector 2-1. The explosion-proof connector 2-1 is a rotary connector with an integrated conductive slip ring structure.

[0021] The regulation feedback system includes four temperature sensors 3-1 positioned at the center of the four steel pipes of the cross-shaped steel pipe 1-2. Each temperature sensor 3-1 is connected to a temperature feedback module 3-2 via wires 3-4. The temperature feedback module 3-2 is fixed to the upper part of the T-shaped steel pipe 1-1. The temperature feedback module 3-2 is connected via wires to a temperature regulator 3-3 fixed to the outer wall of the T-shaped steel pipe 1-1. The temperature feedback module 3-2 can read the temperature sensors 3-1 and is connected to the temperature regulator 3-3 via wires. Figure 2 As shown, the temperature regulator 3-3 can set the target temperature via a switch and temperature adjustment button on the panel. The temperature regulator 3-3 and the temperature feedback module 3-2 form a dynamic linkage. This invention does not involve improvements to the individual components within the regulation feedback system; any existing components that can meet the above functions can be used.

[0022] Workflow:

[0023] 1. Preparation stage:

[0024] The operator opens the lid of the non-curing material container (such as an asphalt sealing container), places the temperature control heating device vertically into the container, and ensures that the cross steel pipe at the bottom of the main structure contacts the bottom of the container, and that the rotating heating tube is surrounded by the non-curing material.

[0025] 2. Power on and start:

[0026] Connect the explosion-proof plug to the industrial explosion-proof power interface, press the power switch on the temperature regulator panel, and start the heating and feedback system.

[0027] 3. Set the target temperature:

[0028] Input the target temperature value (e.g., 150℃ for asphalt) via the switch button on the temperature regulator. The LCD screen will display the set value in real time. Press the confirmation button to activate the closed-loop temperature control program, and the system will enter automatic operation mode.

[0029] 4. Intelligent heating stage:

[0030] The rotating heating element begins 360° radiant heating, with heat penetrating the non-curing material; a temperature sensor (center of the cross-shaped steel tube) monitors the material temperature in real time, and the data is transmitted to the temperature feedback module via wires; the temperature feedback module compares the actual temperature with the target temperature and dynamically adjusts the heating element power using a PID algorithm.

[0031] 5. Construction operations:

[0032] Once the workers receive the warning, they should turn off the power to the heating system and hoist the device out.
