Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the examples and specific implementations.

[0013] like figure 1 As shown, a loading device for air purification filter life testing, its structure includes a motor 1, a screw propulsion device 2, a solution container 3 and a heating plate 4, wherein the motor 1 is connected to the screw propulsion device 2 by transmission, and the screw propulsion device The screw rod of 2 extends through the solution container 3 to the outside of the solution container 3, and a heating plate 4 is arranged below the end of the screw rod propulsion device 2 located outside the solution container 3, and the liquid level of the solution in the solution container 3 is not advanced by the screw rod Screw rod of device 2.

[0014] The solution container 3 is filled with liquid formaldehyde, liquid toluene, liquid xylene or liquid VOC.

[0015] The motor 4 is a variable frequency motor with adjustable speed...

Abstract

The invention relates to a loading device for air-purifying screen life test, structurally comprising a motor, a screw pushing device, a solution container and a heater, wherein the motor is in transmission connection with the screw pushing device, a screw of the screw pushing device is extended through the solution container to the outside thereof, the heater is arranged below the end of the part, outside of the solution container, of the screw of the screw pushing device, and solution level in the solution container exceeds the screw of the screw pushing device. The loading device has the advantages that the loading device is simple in structure and effective; the motor drives the screw pushing device so that a solution under test is continuously dropwise added to the heater from the solution container, and the solution under test is heated and gasified to simulate the condition where an air-purifying screen gains contact with harmful gas; life loading test can be performed effectively on the air-purifying screen; the speed and operation interval of the motor are both adjustable, so that loading rate and interval are adjustable for the solution under test; actual application condition is simulated in a lab.

Description

technical field [0001] The invention relates to a loading device for life testing of an air purification filter screen. Background technique [0002] The service life of the air purification filter is an important factor that determines its quality. It is one of the important processes before the production of the air purification filter to test the length of the service life of the air purification filter after the adsorption of various harmful gases. [0003] In the prior art, there is no device that can conveniently and quickly test the service life of the air purification filter in all directions, and it is impossible to effectively simulate the actual application conditions of the air purification filter. Contents of the invention [0004] The present invention proposes a loading device for testing the life of an air purification filter. Its purpose is to overcome the above-mentioned deficiencies in the prior art, and to provide a device that can flexibly adjust the a...
