Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heating, in particular to an air heater. Background Art
[0002] In the field of mechanical manufacturing, air heaters are usually used to transport high-temperature airflow to various processing equipment. The working principle is as follows: normal temperature airflow enters the pipeline from the inlet of the heating tube, and is heated by the heating wire or heating rod arranged inside the pipeline to form a high-temperature airflow. The high-temperature airflow flows into the equipment through the outlet arranged on the pipeline, forming a high-temperature environment inside the equipment.
[0003] However, the air flow rate is relatively fast, and the air flow in the pipeline is difficult to heat to the preset temperature in a short time, so that the temperature of the gas flowing out from the outlet is relatively low and the heating efficiency is poor. If the heating temperature of the heating rod in the pipeline is increased, although the heating efficiency of the air flow can be improved, the intake temperature of the air flow is difficult to control. When the intake temperature is high, the gas is easily overheated by the heating rod, resulting in inaccurate heating temperature of the air flow. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] like Figure 1-Figure 2 As shown, the utility model provides an embodiment of an air heater, comprising: a pipeline 1 , the pipeline 1 is connected to a heater body 2 , and the heater body 2 is used to heat the airflow in the pipeline 1 .
[0021] Specifically, the pipeline 1 is provided with a mounting portion 11, and the heater body 2 is provided with a fixing portion 21. The mounting portion 11 and the fixing portion 21 are detachably connected. The detachable connection method includes but is not limited to a threaded connection and a snap connection. Preferably, a threaded connection is adopted, an internal thread is provided on the mounting portion 11, and an external thread is provided on the fixing portion 21, so as to facilitate the replacement and maintenance of the pipeline 1 and the heater body 2. The heater body 2 is provided with a plurality of heating rods 22, and the heating rods 22 are provided in the pipeline 1. A plurality of heating rods 22 are provided, and the plurality of heating rods 22 are arranged in a vertical and horizontal structure, so that the gas in the pipeline 1 is evenly heated, and the vertical and horizontal arrangement structure formed by the heating rods 22 is adapted to the inner diameter of the pipeline 1, so that the heating rods 22 are not in contact with the inner wall of the pipeline 1 while reducing the size of the pipeline 1, thereby increasing the heat exchange efficiency when the airflow passes through the pipeline 1.
[0022] Furthermore, a temperature control probe is provided in the pipeline 1 , and the temperature control probe is used to monitor the air flow temperature. The temperature control probe includes a first temperature control probe 3 and a second temperature control probe 4 .
[0023] Among them, the pipeline 1 is provided with an air inlet 12, and a first temperature control probe 3 is provided at one end of the pipeline 1 close to the air inlet 12 for monitoring the temperature of the intake air flow. The pipeline 1 is provided with an air outlet 13, and the air outlet 13 is obliquely arranged on the side wall of the pipeline 1. The air outlet 13 is provided with a second temperature control probe 4 for monitoring the temperature of the outlet air flow.
[0024] In this embodiment, the temperature of the intake air flow and the temperature of the outlet air flow can be monitored by the temperature control probe, so as to timely adjust the temperature of the heater body 2 and make the temperature of the heating rod 22 variable. Specifically, when the flow rate of the air flow is faster, the temperature of the heating rod 22 can be increased by adjusting the heater body 2, thereby increasing the heating speed of the air flow. By setting a second temperature control probe 4 to monitor the outlet temperature of the air flow, the air flow can be quickly heated to the preset temperature, thereby improving the efficiency and accuracy of the air flow heating.
[0025] In the present application, when the intake air flow temperature monitored by the first temperature control probe 3 is low, the temperature of the heating rod 22 is increased so that the outlet air flow temperature monitored by the second temperature control probe 4 reaches a preset temperature. If the intake air flow temperature monitored by the first temperature control probe 3 is high, the temperature of the heating rod 22 is lowered so that the outlet air flow temperature monitored by the second temperature control probe 4 reaches a preset temperature, thereby avoiding overheating caused by the increase in the temperature of the heating rod 22, so that the air flow can be fully heated in the pipeline 1 while avoiding overheating, thereby further improving the accuracy of the air flow heating temperature.
[0026] Working principle: The temperature of the inlet air flow and the outlet air flow can be monitored by the temperature control probe, so as to timely adjust the temperature of the heater body 2 and make the temperature of the heating rod 22 variable. The temperature of the heating rod 22 can be adjusted by adjusting the heater body 2 to heat the air flow.
[0027] In summary, although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
