Description

Technical Field

[0001] The present application relates to the technical field of wellhead antifreeze, and in particular to an antifreeze wellhead heating device. Background Art

[0002] Wellhead antifreeze is an important part of coal mine safety production. In order to avoid ice formation at the wellhead, a heating device is usually required at the wellhead.

[0003] The existing wellhead heating device mainly uses environmentally friendly electric heating and blowing. The fluid medium is heated by electric heating, and then the heated fluid medium is transported to the air outlet of the fan. The fan blows out wind, and the wind exchanges heat with the heated fluid medium to be converted into hot air. The hot air is blown at the wellhead to increase the ambient temperature of the wellhead, making it less likely to freeze at the wellhead.

[0004] The wind exchanges heat with the heated fluid medium at the wind outlet, so that the contact time between the wind and the heated fluid medium is short, resulting in poor heating effect of the heated fluid medium on the wind. Utility Model Content

[0005] In order to improve the heating effect on wind, the present application provides an antifreeze wellhead heating device.

[0006] The present application provides an antifreeze wellhead heating device, which adopts the following technical solution:

[0007] A freeze-proof wellhead heating device comprises a blowing assembly and a heating assembly. The blowing assembly is used to form wind flow. Two groups of heating assemblies are provided and are respectively arranged at the air inlet and the air outlet of the blowing assembly. The heating assembly comprises a water tank, a heating wire and an air duct. The water tank is filled with water. The heating wire is arranged in the water of the water tank. There are multiple air ducts and they are all fixedly penetrated on the water tank along the flow direction of the wind. The air ducts pass through both sides of the water tank.

[0008] By adopting the above technical solution, the electric heating wire heats the water to turn the water into water vapor. The water vapor floats up and wraps around the air duct, and the blowing component forms an airflow. The airflow first flows through the air duct on the water tank located at the air inlet of the blowing component, and is blown out from the air duct on the water tank located at the air outlet of the blowing component. The airflow exchanges heat with the water vapor in the water tank through the air duct, so that the air in the airflow can be heated twice, and the contact time between the wind and the water vapor is increased, thereby improving the heating effect of the wind.

[0009] Optionally, a partition plate is fixedly provided in the water tank, with a spacing left between the partition plate and the top and bottom ends of the water tank, and the water tank is divided into a steam flow channel and a return water flow channel, the heating wire is arranged opposite to the steam flow channel, and a guide plate is fixedly connected to the top of the partition plate, and the guide plate is inclined in the direction away from the partition plate toward the direction away from the return water flow channel.

[0010] By adopting the above technical solution, the partition plate and the guide plate allow the water vapor and condensed water in the water tank to flow separately, so that the water vapor and condensed water form a circulation flow, thereby making it easy for the area around the air duct to be filled with newly generated water vapor.

[0011] Optionally, the blowing assembly includes a support base, a fan and a motor, the fan is rotatably connected to the support base, the motor is fixedly connected to the support base, and the output shaft of the motor is connected to the fan.

[0012] By adopting the above technical solution, the fan can be driven to rotate by the motor, and the fan can form wind flow during the rotation process, thereby easily generating wind flow flowing through the air duct.

[0013] Optionally, the output shaft of the motor is connected to the fan via a belt drive.

[0014] By adopting the above technical solution, the motor drives the fan through a belt drive, so that the axis of the motor and the axis of the fan do not need to be in the same straight line, making it difficult for the motor to exchange heat with the heated airflow, thereby making it difficult for the motor to heat up quickly.

[0015] Optionally, a blowing pipe is connected to the water tank at the air outlet of the blowing assembly. The blowing pipe is located on the side of the water tank away from the blowing assembly. The blowing pipe is arranged along the flow direction of wind. All the air ducts on the water tank are located within the projection range of the blowing pipe on the water tank. A wind direction adjustment assembly is arranged on the end of the blowing pipe away from the water tank. The wind direction adjustment assembly is used to control the direction of wind flow.

[0016] By adopting the above technical solution, the heated air flow is blown out from the blowing pipe, and the direction of the air flow can be regulated by the wind direction adjustment component, thereby expanding the blowing range of the air flow and making the use of the heating device more flexible.

[0017] Optionally, the wind direction adjustment component includes a plurality of adjustment plates arranged in parallel, and the middle parts of both ends of the adjustment plates are rotatably connected to the inner wall of the blowing pipe.

[0018] By adopting the above technical solution, the adjusting plate can guide the blowing direction of the wind flow, and the blowing direction of the wind flow can be conveniently controlled by rotating the adjusting plate.

[0019] Optionally, the wind direction adjustment assembly further includes an adjustment rod, which is located on one side of the rotation axis of the adjustment plate, and the adjustment rod is hinged to all the adjustment plates.

[0020] By adopting the above technical solution, all the adjusting plates can be rotated synchronously through the adjusting rod, thereby improving the adjustment efficiency of the adjusting plates.

[0021] Optionally, the blowing pipe is rotatably connected to the water tank, and a handle is fixedly provided on the outer wall.

[0022] By adopting the above technical solution, the direction of the rotation axis of the adjusting plate can be adjusted by rotating the blowing pipe by the handle, thereby expanding the control range of the blowing direction of the wind flow and further improving the flexibility of the use of the heating device.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting water tanks at the air inlet and outlet of the fan to heat the air, the number of times the air is heated and the contact time between the air and the heat source are increased, thereby improving the heating effect of the air;

[0025] 2. The motor drives the fan through a belt drive, so that the heated air is not easy to blow on the motor, making the motor not easy to heat up quickly;

[0026] 3. By setting the blowing pipe, adjusting plate and adjusting rod, the direction of the air flow after heating can be easily adjusted. BRIEF DESCRIPTION OF THE DRAWINGS
