Description

Low-resistance air filter

Technical Field

The utility model relates to a clarification plant technical field, in particular to low resistance air cleaner.

Background

The development of modern industry places ever higher demands on experimental, research and production environments, and the main way to achieve this is to use air filters widely in clean air conditioners. Wherein High Efficiency (HEPA) ultra high efficiency (ULPA) filter is the last protection that the dust particle gets into the clean room, therefore its performance is good and bad and directly influences the clean room grade, and life further influences the change frequency of clean room filter.

The traditional PTFE and glass fiber filter element material adopts continuous hot melt adhesive to fold and fix the PTFE and glass fiber filter element material, and has a main position in the field of air filters due to simple and common process mode; however, the structure is tightly packed, so that the requirement of low resistance cannot be better met, and the purpose of energy conservation is not realized.

Therefore, there is a need to develop a new filter structure to meet the needs of the present society.

SUMMERY OF THE UTILITY MODEL

The main object of the utility model is to provide a low resistance air cleaner makes the effect that better reaches the low resistance under the condition that the dust particle that enters into the toilet reduces as far as possible.

The utility model discloses a following technical scheme realizes above-mentioned purpose: the utility model provides a low resistance air cleaner, includes the frame, locates filter core in the frame with protect in the protecting wire net of the both sides of filter core, the filter core is made a round trip to fold by the filter cloth and is formed, connect with the division strip that the hot melt adhesive formed between the dog-ear of filter cloth.

Specifically, the filter cloth extends along the length direction of the outer frame, and the crease is along the width direction of the outer frame.

Specifically, the filter cloth is made of polytetrafluoroethylene or glass fiber.

Specifically, the outer frame is an aluminum frame.

Specifically, the material of the protective net is 304 stainless steel.

Adopt above-mentioned technical scheme, the utility model discloses technical scheme's beneficial effect is:

the utility model discloses an adopt the parting strip that discontinuous hot melt adhesive formed to connect the dog-ear, both guaranteed the stable in structure of filter core, make the air flow in the space moreover, realize the low resistance of filter core, the life of extension filter core.

Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 1 to 3, the utility model discloses a low resistance air filter, including frame 1, locate filter core 2 in frame 1 and protect in the protecting wire net 3 of filter core 2 both sides, filter core 2 is made a round trip to fold by filter cloth 21 and is formed, connects with the parting strip 22 that the hot melt adhesive formed between the dog-ear of filter cloth 21. The filter cloth 21 has a large passing area after being folded, and plays a good role in filtering air during passing through. Since the folded filter cloth 21 has an unstable structure, the peaks and valleys need to be adhered by hot melt adhesive to form a stable structure. The separating strips 22 provide support and a simple separation of the filter cloth 21. Because the hot melt adhesive only adheres between the folding corners, and the hollow space is reserved below, air can still flow between the blocks after reaching the filter element 2, if the resistance of a certain part is increased, the air can pass through another position to be filtered, so that the integral passing resistance of the air is smaller, and the service life of the filter element 2 is longer.

As shown in fig. 1 and 2, the filter cloth 21 extends in the longitudinal direction of the outer frame 1, and the fold lines extend in the width direction of the outer frame 1. Therefore, the filter cloth 21 has narrow width requirement, longer length and less material breaking times.

The filter cloth 21 is made of polytetrafluoroethylene or glass fiber. The polytetrafluoroethylene and the glass fiber have good filtering efficiency and are easy to clean.

The outer frame 1 is an aluminum frame. The aluminum frame has small density and firm structure, so the aluminum frame has light weight and convenient installation.

The material of the protective net 3 is 304 stainless steel. The protecting net 3 is protected on two sides of the filter element 2, the function of protecting the filter element from being damaged is achieved, the 304 stainless steel structure is firm, and cost is low.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
