Abstract
The invention relates to an air heater. The air heater comprises: a cavity is used for accommodating air; an air inlet for sucking air and an air outlet for exhausting air are formed in the cavity; an electric heating bar is mounted on the inner cavity wall of the cavity; an electric heating controller is arranged in the cavity; and a waterproof sealing ring is arranged at the matched position of the electric heating controller and the inner cavity wall of the cavity. By the mode, the invention provides the air heater. The air heater is widely applied to filter testing equipment, can heat the air quickly and efficiently, can monitor the heating temperature of the air in real time, is safe and reliable, and facilitates wide popularization.
Description
Technical field
The present invention relates to the air cleaning facility field, particularly relate to a kind of air heater.
Background technology
Air cleaning facility is widely used in the industrial production, and the testing equipment of air filter also has been subject to using widely as the main tool of check air filter.In the filter testing equipment, need to send out dirt to the air that sucks and process; Then to add hot-air when sending out dirt, the particle ability of carrying of air is promoted.Traditional dirt device of sending out just simply carries out aerocolloidal spraying to air; The dynamics of carrying of air is too little like this, and it is even to carry density unevenness, can cause the error of record data, affects the power of test of testing equipment, can not get equally accurately product quality parameters.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of air heater, and it is reasonable in design, and is simple in structure.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts provides a kind of air heater, comprising: the cavity that holds air; Described cavity is provided with the air inlet of air amount and discharges the air outlet of air; On the internal chamber wall of described cavity electrical bar is housed; Also be provided with electrical heating controller in the described cavity; The internal chamber wall cooperation place of described electrical heating controller and cavity is provided with waterproof grommet.
Preferably, described electrical bar is the ceramic electrical hot pin.
The invention has the beneficial effects as follows: a kind of air heater is provided, and this air heater applies in the filter testing equipment widely.It can rapidly and efficiently heat air, and the heating-up temperature of Real-Time Monitoring air, and is safe and reliable, is easy to extensive popularization.
Description of drawings
Fig. 1 is the principle schematic of a kind of air heater of the present invention;
The mark of each parts is as follows in the accompanying drawing: 1, cavity; 2, air inlet; 3, air outlet; 4, electrical bar; 5, electrical heating controller.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also accompanying drawing 1, the embodiment of the invention comprises:
A kind of air heater comprises: the cavity 1 that holds air; Described cavity 1 is provided with the air inlet 2 of air amount and discharges the air outlet 3 of air; Electrical bar 4 is housed on the internal chamber wall of described cavity 1; Also be provided with electrical heating controller 5 in the described cavity 1; Described electrical heating controller 5 is provided with waterproof grommet with the internal chamber wall cooperation place of cavity 1.Described electrical bar 4 is the ceramic electrical hot pin.
During work, by electrical heating controller is regulated, heating chamber is heated, the compressed air of flowing through is heated, make its outlet temperature reach setting value.
The invention provides a kind of air heater, this air heater applies in the filter testing equipment widely.It can rapidly and efficiently heat air, and the heating-up temperature of Real-Time Monitoring air, and is safe and reliable, can regulate arbitrarily required temperature, is easy to extensive popularization.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
