Abstract

The utility model relates to the technical field of drying structures, in particular to a three-way type drying structure for a pipeline type respirator.

Description

Three-way type pipeline formula is stoving structure for respirator

Technical Field

Background

Among the prior art, the filtration that uses in the respirator, its equal vertical arrangement of filter core are inside the body of respirator, however this kind of arrangement, and the body needs frequently to be dismantled in the change of filter core, and the body is inside can directly drip on filter core upper portion because of the drop of water that the condensation formed in addition, leads to the filter core to wet, influences the filter effect, increases the inside pressure of body.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problem of how to keep the filter element dry.

In order to solve the technical problem, the utility model provides a tube body, wherein the lower part of the tube body is provided with an air inlet, the upper part of the tube body is provided with an air outlet, and the tube body is characterized in that: a water return pipe is arranged at a position, close to the air inlet, of one side of the outer portion of the pipe body, and the air inlet is provided with a butterfly valve connected with the opening of the pipe body; an evaporation pipe is arranged at a position, close to the air outlet, of one side of the outer portion of the pipe body, and a heating assembly is arranged at a position, close to the air inlet, of one end of the inner portion of the pipe body.

According to the utility model, the heating component is arranged in the pipe body and is combined with the water return pipe and the evaporation pipe, so that the efficient evaporation of water drops in the pipe body can be realized, and the problem that the filtering effect is influenced because the filter element is easily wetted by excessive water drops is solved.

Detailed Description

The utility model relates to a drying structure for a three-way pipeline type respirator, which comprises a pipe body 1 as shown in a figure 1-2, wherein the lower part of the pipe body 1 is provided with an air inlet 2, the upper part of the pipe body 1 is provided with an air outlet 3, and the drying structure is characterized in that: a water return pipe 4 is arranged at a position, close to the air inlet 2, on one side of the outer part of the pipe body 1, and the air inlet 2 is provided with a butterfly valve 5 connected with the opening of the pipe body 1; an evaporation tube 6 is arranged at a position, close to the air outlet 3, on one side of the outer portion of the tube body 1, and a heating assembly is arranged at a position, close to the air inlet 2, at one end of the inner portion of the tube body 1.

As shown in fig. 1-2, the heating assembly includes a case 7, a thermocouple 8, and a heating rod 9; the position that body 1 outside one side is close to air inlet 2 is provided with box 7, the inside heating rod 9 that penetrates the barrel that is provided with of box 7, the vertical direction of heating rod 9 upper portion is provided with thermocouple 8 in box 7 inside.

As shown in fig. 1-2, a filter opening 10 is provided at a position close to the air outlet 3 at one end inside the pipe body 1, the filter opening 10 is arranged in an inclined manner, a filter element 11 is provided inside the filter opening 10, a heat tracing band 12 is provided at a lower end of the filter element 11, a cover plate 13 is provided at one end of the filter opening 10, and the cover plate 13 is fastened with the pipe body 1.

As shown in fig. 1-2, a flow guide plate 14 is disposed on the inner wall of the tube body 1 between the air outlet 3 and the filtering openings 10, and the flow guide plate 14 is obliquely disposed and welded on the inner wall of the tube body 1.

When a user uses the drying structure manufactured by the utility model, external air passes through the butterfly valve 5 and the air inlet 2, then passes through the filter element 11 of the filter opening 10 to be filtered, and then reaches the air outlet 3, and the temperature of the air outlet 3 is slightly lower than that of the air inlet 2, so that water vapor is easily condensed into water drops, and then flows to the bottom of the filter opening 10 along the flow guide plate 14, if the water drops are accumulated less, the water drops pass through the heat tracing band 12 at the lower part of the filter element 11 to be dried at low temperature and evaporated, if the water drops are accumulated more, the water drops flow into the box body 7 along the water return pipe 4, then the thermocouple 8 in the box body 7 drives the heating rod 9 to dry the water drops in the box body 7 at high temperature, and the evaporated water vapor reaches the air outlet 3 through the evaporation pipe 6, so that the filter element 11 is kept in a dry state continuously, and the filtering effect is ensured.

It is to be understood that the present invention has been described with reference to certain embodiments, and that various changes in the features and embodiments, or equivalent substitutions may be made therein by those skilled in the art without departing from the spirit and scope of the utility model. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the utility model without departing from the essential scope thereof. Therefore, it is intended that the utility model not be limited to the particular embodiment disclosed, but that the utility model will include all embodiments falling within the scope of the appended claims.
