Description

Technical Field

[0001] This utility model relates to the field of filter element testing technology, and in particular to a filter element integrity testing device. Background Technology

[0002] Filter integrity testing refers to a series of tests performed on the filter element before or during use to ensure that the filter element is structurally intact, free of cracks and contamination, and that its service life and filtration effect are guaranteed.

[0003] Traditional methods for testing filter integrity include the bubble spot test, pressure test, water immersion test, and fluorescent reagent test, among which the pressure test method is particularly important. Figure 1 As shown, the filter element 3 to be tested is installed inside the test housing 2, and the bottom of the test housing 2 is provided with a housing flange 4. The filter element integrity testing device also includes a test base, which includes support legs 7 and a base flange 8 fixed to the upper end of the support legs. In use, the housing flange 4 and the base flange 8 are connected by clamps 5, and then the water pipe is connected to the liquid injection port 1 at the upper end of the test housing. The base flange is provided with a flange water permeation hole 6. Water flows through the filter element and then out through the flange water permeation hole on the base flange. The pressure difference between the inside and outside of the filter element is detected by a pressure sensor to determine the integrity of the filter element.

[0004] The existing filter integrity testing device has the following problems: the test base itself is not very heavy, and during the process of installing the test housing on the test base, another person is needed to hold the test base in place, which is time-consuming and laborious. In addition, the liquid discharged from the filter element flows directly to the ground through the base flange, which will cause a large area of ​​dirt on the ground, which is also time-consuming and laborious to clean. Utility Model Content

[0005] The purpose of this invention is to provide a filter cartridge integrity tester to solve the technical problem in the prior art where the test liquid flows directly to the ground and contaminates the ground.

[0006] To solve the above-mentioned technical problems, the technical solution of the filter element integrity tester of this utility model is as follows:

[0007] A filter cartridge integrity testing device includes a test base and a test housing for mounting the filter cartridge under test. The test base includes a horizontally arranged base flange, and the bottom of the test housing is provided with a housing flange for connecting to the base flange. The base flange is provided with a flange water permeation hole. The test base also includes a liquid collection cylinder with an open upper end. The bottom of the liquid collection cylinder is provided with a collection cylinder water outlet hole, and a collection cylinder water outlet pipe is provided at the collection cylinder water outlet hole. The collection cylinder water outlet pipe is provided with a water outlet pipe valve. The bottom of the liquid collection cylinder is provided with a collection cylinder support leg. The base flange is fixed to the upper side of the bottom of the liquid collection cylinder through the base support leg structure. The flange water permeation hole communicates with the inner cavity of the liquid collection cylinder.

[0008] Furthermore, the top height of the test housing is higher than the top height of the liquid collection cylinder.

[0009] Furthermore, the top of the test housing is provided with an injection port for injecting liquid or gas.

[0010] Furthermore, a first rigid pipe and a second rigid pipe are fixed vertically on the outer side of the liquid collection cylinder wall. The lower end of the first rigid pipe is connected to a corresponding liquid source, and the lower end of the second rigid pipe is connected to a corresponding gas source. The upper end of the first rigid pipe is connected to a water injection hose for injecting water into the filling port, and the upper end of the second rigid pipe is connected to an air injection hose for injecting air into the filling port.

[0011] Furthermore, a water receiving trough communicating with the water inlet of the flange is provided on the lower side of the base flange, and a water pipe leading to the bottom of the liquid collection cylinder is connected to the water receiving trough.

[0012] Furthermore, the base support leg structure includes a first flange fixed to the upper side of the bottom of the liquid collection cylinder via the first support leg, a base flange fixed to the upper end of the second support leg, a second flange provided at the lower end of the second support leg, and the second flange and the first flange being detachably connected by bolts.

[0013] The beneficial effects of this utility model are as follows: When using the filter element integrity testing device of this utility model, the housing flange is connected to the base flange, and the testing process is the same as the prior art. The water discharged through the filter element is collected by the liquid collection cylinder and then discharged in a directional manner through the water outlet pipe of the collection cylinder, which will not cause large-area ground pollution and does not require extensive cleaning. In addition, the setting of the liquid collection cylinder also increases the weight of the entire test base, making the testing process more stable. Attached Figure Description

[0018] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0019] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0020] An example of an implementation of a filter cartridge integrity tester in this utility model. Figure 2 As shown: The test housing includes a test base and a test housing 2 for mounting the filter element under test. The test base includes a horizontally arranged base flange 8. The bottom of the test housing has a housing flange 4 for connecting to the base flange via clamps. The base flange 8 has a flange permeable hole. The top of the test housing has a filling port 1 for liquid or gas injection. All of the above are existing technologies and will not be described in detail here.

[0021] The test base also includes a liquid collection cylinder 15 with an open top. The bottom 14 of the liquid collection cylinder 15 has an upward-facing arc-shaped structure. A water outlet is provided at the bottom of the liquid collection cylinder, and a water outlet pipe 21 is provided at the water outlet. A water outlet valve is provided on the water outlet pipe 21. A collection cylinder support leg 20 is provided at the bottom of the liquid collection cylinder. The collection cylinder support leg 20 is used to raise the height of the liquid collection cylinder so that the bottom of the liquid collection cylinder has installation space. The collection cylinder water outlet pipe 21 and the water outlet valve are located in this installation space.

[0022] The base flange is fixed to the upper side of the bottom of the liquid collection cylinder via the base support leg structure, and the flange water permeable hole is connected to the inner cavity of the liquid collection cylinder.

[0023] In this invention, the top height of the test housing 2 is higher than the top height of the liquid collection cylinder 15.

[0024] The base support structure includes a first flange 12 fixed to the upper side of the bottom of the liquid collection cylinder via a first support leg 13, a base flange 8 fixed to the upper end of a second support leg 11, and a second flange 22 provided at the lower end of the second support leg 11. The second flange 22 is detachably connected to the first flange 12 by bolts. In other words, the second flange, the second support leg, and the base flange at the upper end of the second support leg are all replaceable. When testing filter elements of different specifications and models, the required test housing size varies, and the diameter of the housing flange at the bottom of different test housings will differ. In this case, different sized base flanges can be used to accommodate housing flanges of different diameters.

[0025] A water receiving trough 9 is provided on the lower side of the base flange, which is connected to the water inlet of the flange. The water receiving trough 9 is located on the upper side of the second flange, and a water pipe 10 leading to the bottom of the liquid collection cylinder is connected to the water receiving trough 9.

[0026] A first rigid pipe 16 and a second rigid pipe 18 are fixed vertically on the outer side of the liquid collection cylinder wall. The lower end of the first rigid pipe 16 is connected to a corresponding liquid source, and the lower end of the second rigid pipe 18 is connected to a corresponding gas source. The upper end of the first rigid pipe is connected to a water injection hose 17 for injecting water into the filling port, and the upper end of the second rigid pipe is connected to an air injection hose 19 for injecting air into the filling port. The water injection hose and the air injection hose are used separately. When the filter element needs to be tested for integrity by injecting water, the water injection hose is connected to the filling port to inject water into the filter element; when the filter element needs to be tested for integrity by injecting air, the air injection hose is connected to the filling port to inject air into the filter element.

[0027] During the water filling test, the water passing through the filter element flows into the water receiving tank through the flange water inlet, and then flows through the water pipe to the bottom of the liquid collection cylinder, where it is collected. Finally, it is discharged in a directional manner through the water outlet pipe of the collection cylinder, thus avoiding the problem of large-area water pollution that cannot be cleaned.
