Description

Technical Field

[0001] This utility model relates to the field of respirator technology, and in particular to a multi-filter respirator. Background Art

[0002] With the rapid development of industry, the working environment is becoming increasingly complex, and the production materials are becoming more diversified.

[0003] Most existing tank-top breathers are equipped with only one filter element, and the filtration effect is limited. When facing a high-efficiency production environment, the filter element has a short lifespan and poor filtration effect, which cannot meet the requirements of safe operation. Therefore, in order to solve the above problems, this application proposes a multi-filter breather. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-filter respirator. This device allows for filter replacement, effectively improving the respirator's filtration capacity, extending the filter's lifespan, and enhancing safety during use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-filter respirator includes an air intake hopper, a head fixedly connected to the top of the air intake hopper, an end plate fixedly connected to the top of the end plate, a retaining ring fixedly connected to the outer wall of the end plate, a cylinder fixedly connected to the top of the retaining ring, a sealing head fixedly connected to the top of the cylinder, multiple PTFE microporous filter elements sealed and installed on the end plate, a water receiving tray fixedly connected to the outer wall of the end plate, and a drain pipe fixedly connected to the bottom of the water receiving tray.

[0007] Preferably, the number of PTFE microporous filter elements is set to five, and the plurality of PTFE microporous filter elements are distributed at equal intervals.

[0008] Preferably, the end plate has multiple sealing ports through it, the bottom outer wall of the PTFE microporous filter element has external threads, and the inner wall of the sealing port has internal threads that mate with the external threads.

[0009] Preferably, a flange is fixedly connected to the outer wall of the PTFE microporous filter element, and the bottom of the flange abuts against the top of the end plate.

[0010] Preferably, the end plate has multiple through holes that are evenly spaced.

[0011] Preferably, the bottom of the water receiving tray is set with the left side higher than the right side, and the drain pipe is located at the bottom of the water receiving tray.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. Multiple PTFE microporous filter elements can filter the circulating air, intercepting and filtering dust and impurities in the air. The purified air is discharged through multiple holes along the inner wall of the cylinder, thus achieving air purification.

[0014] 2. The air inside the sanitary tank contains moisture. When the air comes into contact with the inner wall of the cylinder, it will be pre-cooled and liquefied. Water droplets will drip down the inner wall of the cylinder and collect in the water collection tray, and then be discharged through the drain pipe.

[0015] 3. The cylinder and sealing head can be removed by unscrewing the bolts between the fixing ring and the cylinder body. The operator can then remove the PTFE microporous filter element by holding it and rotating it. The PTFE microporous filter element can be replaced according to actual needs, thus expanding the scope of application.

[0016] In summary, this device allows for filter replacement, effectively improving the respirator's filtration capacity, extending the filter's lifespan, and enhancing safety during use. Attached Figure Description

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figures 1-4The multi-filter respirator includes an air intake hopper 1, the bottom of which is connected to the top of an external sanitary tank for air filtration. A head 2 is fixedly connected to the top of the air intake hopper 1, and an end plate 3 is fixedly connected to the top of the end plate 2. A fixing ring 4 is fixedly connected to the outer wall of the end plate 3, and a cylinder 5 is fixedly connected to the top of the fixing ring 4. The fixing ring 4 and the cylinder 5 are installed and sealed together by multiple bolts and a flange. The cylinder 5 can be removed by unscrewing the bolts to disassemble and replace the PTFE microporous filter element 6. A sealing head 7 is fixedly connected to the top of the cylinder 5. The air intake hopper 1, head 2, fixing ring 4, cylinder 5, and sealing head 7 together form a tank to purify the air.

[0024] Multiple PTFE microporous filter elements 6 are sealed and installed on the end plate 3 to achieve air filtration and purification. The number of PTFE microporous filter elements 6 is set to five, and the multiple PTFE microporous filter elements 6 are distributed at equal intervals. Multiple sealing ports 10 are opened through the end plate 3. The bottom outer wall of the PTFE microporous filter element 6 is provided with external threads, and the inner wall of the sealing port 10 is provided with internal threads that mate with the external threads. The outer wall of the PTFE microporous filter element 6 is fixedly connected to a flange 11, and the bottom of the flange 11 is set to abut against the top of the end plate 3. By replacing the PTFE microporous filter element 6, different filter elements can be replaced according to actual needs, thus expanding the range of applications.

[0025] Multiple through holes 12 are provided through the end plate 3. The multiple through holes 12 are distributed at equal intervals. A water receiving tray 8 is fixedly connected to the outer wall of the end cap 2. A drain pipe 9 is fixedly connected to the bottom of the water receiving tray 8. The inner bottom of the water receiving tray 8 is set with the left side higher than the right side. The drain pipe 9 is set at the bottom of the water receiving tray 8. The water receiving tray 8 is used to guide external condensate to prevent water accumulation.

[0026] In this invention, the air inlet hopper 1 is connected to the top of the sanitary tank. Air from inside the sanitary tank is injected into the end cap 2 and the cylinder 5 through the air inlet hopper 1. Multiple PTFE microporous filter elements 6 can filter the circulating air, intercepting and filtering dust and impurities in the air. The purified air is discharged along the inner wall of the cylinder 5 through multiple through holes 12, thus achieving air purification. The air inside the sanitary tank contains moisture. When the air comes into contact with the inner wall of the cylinder 5, it will be pre-cooled and liquefied, and water droplets will drip down along the inner wall of the cylinder 5 and collect in the water collection tray 8, and be discharged through the drain pipe 9. When it is necessary to replace the PTFE microporous filter element 6, the cylinder 5 and the end cap 7 can be removed by unscrewing the bolts between the fixing ring 4 and the cylinder 5. The operator can then hold the PTFE microporous filter element 6 and rotate it to remove it for replacement. Different filter elements can be replaced according to actual needs, expanding the scope of application.

[0027] This invention solves the problem that existing technologies suffer from short filter life and poor filtration efficiency when facing high-efficiency production environments, thus failing to meet the requirements of safe operation, by replacing the filter element.
