Abstract
The utility model relates to the technical field of filter structures, in particular to a filter structure for a three-way type pipeline type respirator.
Description
Technical Field
The utility model relates to the technical field of filter structures, in particular to a filter structure for a three-way pipeline type respirator.
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 problems that the filter element is inconvenient to replace and is easy to wet.
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: the body is provided with the filtration mouth in the middle position, the filtration mouth is the slope and arranges, the inside filter core that is provided with of filtration mouth, filtration mouth one end is provided with the apron, lock joint between apron and the body.
Because the inclined filtering port is arranged in the pipe body, the filter element is convenient to replace, water drops are prevented from directly dropping on the filter element, and the problems that the filter element is inconvenient to replace and is easy to wet are solved.
Drawings
Fig. 1 is an overall structural front view of a filter structure for a three-way pipe type respirator.
Fig. 2 is a rear view of the overall structure of a filter structure for a three-way tubular respirator.
In the figure: 1. a tube body; 2. an air inlet; 3. an air outlet; 4. a filter port; 5. a filter element; 6. a cover plate; 7. a drainage plate; 8. a concentration detection port; 9. a dust generating port; 10. a ball valve; 11. a heat tracing band.
Detailed Description
The utility model relates to a filter structure for a three-way pipeline type respirator, which comprises a pipe body 1 as shown in figures 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 filter structure is characterized in that: body 1 is provided with filtration mouth 4 in the middle position, filtration mouth 4 is the slope and arranges, the inside filter core 5 that is provided with of filtration mouth 4, 4 one ends of filtration mouth are provided with apron 6, the lock joint between apron 6 and the body 1.
As shown in fig. 1-2, a flow guide plate 7 is arranged on the inner wall of the tube body 1 between the air outlet 3 and the filtering port 4, and the flow guide plate 7 is obliquely arranged and welded on the inner wall of the tube body 1.
As shown in fig. 1-2, a concentration detection port 8, a dust generation port 9 and a ball valve 10 for sterilization are sequentially arranged on the inner wall of the pipe body 1 from top to bottom between the filtering port 4 and the air inlet 2.
As shown in fig. 1-2, the lower end of the filter element 5 inside the filter opening 4 is provided with a heat tracing band 11.
When a user uses the filtering structure manufactured by the utility model, the filter element 5 is placed in the filtering opening 4 and sealed by the cover plate 6 by arranging the inclined filtering opening 4, the air reaches the filtering opening 4 through the air inlet 2, is filtered by the filter element 5 and then is discharged through the air outlet 3, the air is cooled at the air outlet 3 to form vapor or small water drops which are easy to drop on the upper part of the filter element 5 of the filtering opening 4 to wet the filter element 5, so that the filtering effect of the filter element 5 is influenced, for this reason, the drainage plate 7 which is arranged in an inclined manner is arranged between the filtering opening 4 and the air outlet 3 and is used for draining or attaching the small water drops which are formed by condensation, if the water drops are more condensed, the water drops flow down along the inner wall of the cylinder body and reach the bottom position of the filter element 5, the bottom position of the filter element 5 is provided with the heat tracing band 11 which can properly dry the filter element 5, the water drops are prevented from being gathered in the filter element 5, and the water drops are discharged from the air outlet 3 in the form of water vapor.
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.
