Description

Technical Field

[0001] The utility model relates to the technical field of hot air heaters, in particular to an industrial hot air heater which is convenient for filtering lint. Background Art

[0002] The industrial hot air heater is composed of three parts: a blower, a heater, and a control circuit. The working principle is as follows: after power is turned on, the blower blows air into the heater, allowing the air to pass evenly from the inside and outside of the spiral heating wire. The heat generated by the heating wire after power is turned on exchanges heat with the cold air passing through, thereby increasing the air temperature at the air outlet; the K-type thermocouple at the air outlet promptly feeds back the detected air outlet temperature to the temperature controller, and the instrument monitors the actual working temperature according to the set temperature, and transmits the relevant information back to the solid-state relay to control whether the heater is working; however, when the existing industrial hot air heater is in use, the fluff contained in the air will enter the industrial hot air heater with the air, and then the fluff will accumulate in the industrial hot air heater. The long-term accumulation of fluff in the industrial hot air heater will affect the air heating efficiency. At the same time, when the industrial hot air heater is hot, the fluff will cause the fluff to catch fire and cause the entire industrial hot air heater to catch fire, posing a great safety hazard; therefore, an industrial hot air heater that is easy to filter fluff is proposed to solve the above problems. Summary of the invention

[0003] The purpose of the utility model is to solve the above problems and to provide an industrial hot air heater which is convenient for filtering lint.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An industrial hot air heater for filtering lint, comprising a hot air heater body and an air guide pipe arranged at the air inlet end of the hot air heater body, a shell is arranged on the air guide pipe, a semicircular notch is opened on the shell, a filter is arranged in the shell, and an air inlet pipe is arranged on one side of the shell;

[0006] The filter element comprises an inner shell arranged in the shell body, a filter screen is arranged in the inner shell, an arc-shaped shell is arranged on the inner shell, an annular cavity is formed between the arc-shaped shell and the inner shell, and a handle is arranged on the arc-shaped shell.

[0007] Preferably, the filter screen is a spiral structure.

[0008] Preferably, an annular rubber ring is provided on the side surface of the inner shell.

[0009] Preferably, L-shaped grooves are symmetrically provided on the inner wall of the shell, and a clamping block matching the L-shaped groove is provided on the inner shell.

[0010] Preferably, the arc length of the arc-shaped shell is smaller than the arc length of the shell notch.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0012] The utility model uses a filter element to filter the air entering the hot air heater body, thereby preventing lint from entering the hot air heater body and causing the hot air heater body to catch fire, which is beneficial to the use of the hot air heater body. The annular rubber ring is used to improve the sealing between the inner shell and the outer shell, thereby preventing air leakage between the inner shell and the outer shell, so that all the gas enters the hot air heater body and the air supply is guaranteed. The inner shell is conveniently fixed by the use of a clamping block and an L-shaped groove, thereby fixing the filter screen, which is simple and convenient to operate. At the same time, the filter screen can be disassembled by pushing the handle, which is simple to operate and can achieve quick installation or disassembly of the filter screen.
