[0002] A disc filter element refers to a filter body formed by a metal mesh, a metal sintered felt, and a metal powder material through a special process, mainly a disc-shaped product. Compared with the traditional columnar filter body, it has the advantages of high strength, light weight, and good sealing performance. It has been widely used in industries such as petrochemical, papermaking, water treatment, and polymer, and is gradually being applied to industries such as pharmaceuticals, food, and environmental protection.

[0003] Most of the disc filter elements used in each industry in the past were small in size and poor in accuracy, and no precise performance detection was carried out. With the gradual improvement of the process level of each industry, the market demand for high-precision disc filter elements is also increasing; when making high-precision disc filter elements, it often encounters problems such as inability to detect, and the existing tooling cannot accurately detect the product performance and determine whether the product meets the on-site use requirements.

[0004] When making high-precision disc filter elements, the performance detection of the first piece is extremely important. It will not only affect the accuracy of the final filter element and the performance quality of the batch, but also have a certain impact on the delivery of the product. If this process is not strictly detected, it will lead to a decline in product performance and the inability to continue production; at present, the processes of high-precision disc filter elements on the market are all different, and their use performances are also different, without a unified standard. The lack and simplicity of the detection tooling will greatly reduce the yield rate of the finished product and cannot ensure the safety and reliability of the product; therefore, a set of tooling that can assist in completing the detection work of disc filter elements is urgently needed.

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0015] Please refer to Figures 1-3, the present utility model provides a technical solution: a new type of special detection tooling suitable for high-precision disc filters, including an upper end cover 1 and a lower end cover 2. The upper end cover 1 and the lower end cover 2 are made of all-aluminum material. The upper end cover 1 and the lower end cover 2 are connected by a threaded connection. An air inlet is provided on the upper end cover 1. The connection between the upper end cover 1 and the lower end cover 2 is a stepped structure. An annular groove is formed between the upper end cover 1 and the lower end cover 2. And a filter disc 4 is fixed between the upper end cover 1 and the lower end cover 2. The upper end cover 1 is evenly provided with air outlet holes 5. The air outlet holes 5 correspond to the inner side of the filter disc 4. The upper and lower surfaces of the filter disc 4 are respectively sealed with the connection parts of the upper end cover 1 and the lower end cover 2 by a sealing ring 6. The upper end cover 1 and the lower end cover 2 are respectively provided with annular clamping grooves for positioning the sealing ring 6. The air inlet is located at the center of the upper surface of the upper end cover 1, and an integrally connected air inlet joint 3 is provided at the upper end of the air inlet. Through the air inlet joint 3, it can be connected to an external air permeability detection table. Specifically, during detection, an outer airbag is connected to the air outlet of the air inlet joint 3. The gas inside the airbag enters the cavity between the upper end cover 1 and the lower end cover 2 through the air inlet joint 3. The gas inside the upper end cover 1 and the lower end cover 2 runs out through the air outlet holes 5, and then the gas diffuses out from the inner side of the filter disc 4. Then, by detecting the air pressure change inside the airbag per unit time, the accuracy of the filter disc 4 is detected. This device can prevent in advance the disadvantages of the filter elements processed by the prior art, such as poor integrity and difficult precision control, making the filter elements manufactured have stable quality, good integrity, high dimensional accuracy, and high qualified rate of finished workpieces, to meet the actual problem that there is no detection tooling available when manufacturing high-precision disc filters in the market. This new type of special detection tooling suitable for high-precision disc filters has a simple and reasonable structure, is convenient for mechanical manufacturing, use and disassembly, and the main body uses conventional metal materials, which is conducive to being widely promoted to the market, and solves the problem that it is difficult to control the manufacturing precision of the filter body of high-precision disc filters in the past.

[0016] During use: First, the filter disc 4 is sleeved from the lower end of the upper end cover 1 to the outside, then the upper end cover 1 and the lower end cover 2 are connected by threads. The filter disc 4 is pressed by the upper end cover 1 and the lower end cover 2. Then, through the sealing ring 6, the connection between the filter disc 4 and the upper end cover 1 and the lower end cover 2 is made tighter to prevent inaccurate detection. Through the air inlet joint 3, it can be connected to an external air permeability detection table. Specifically, during detection, an outer airbag is connected to the air outlet of the air inlet joint 3. The gas inside the airbag enters the cavity between the upper end cover 1 and the lower end cover 2 through the air inlet joint 3. The gas inside the upper end cover 1 and the lower end cover 2 runs out through the air outlet holes 5, and then the gas diffuses out from the inner side of the filter disc 4. Then, by detecting the air pressure change inside the airbag per unit time, the accuracy of the filter disc 4 is detected, so as to prevent in advance the disadvantages of the filter elements processed by the prior art, such as poor integrity and difficult precision control.
