Description

A device for testing the pore size of high-temperature resistant filter materials Technical Field

[0001] This utility model relates to the field of filter material production technology, specifically a pore size testing device for high-temperature resistant filter materials. Background Technology

[0002] High-temperature resistant filter materials are widely used in metallurgy, chemical industry, power industry, aerospace and other fields, mainly for harsh environments such as high-temperature flue gas filtration, catalyst carriers, and gas purification. Their core performance indicators (such as filtration efficiency, air permeability, and mechanical strength) directly depend on the material's pore size, pore size distribution, and pore structure. Therefore, accurately measuring the pore size characteristics of high-temperature resistant materials under high-temperature environments is of great significance for optimizing material design, evaluating performance under actual operating conditions, and ensuring the safe operation of equipment.

[0003] For example, Chinese utility model patent CN220982222U proposes a filter material pore size testing device, relating to the field of filter material production technology. This utility model includes a device body, with a motor mounted on the upper side of an upper chamber. A rotating plate is fixed to the motor's power output shaft, and bosses are evenly fixed to the upper wall of the rotating plate. Perforations are evenly distributed on the lower wall of a guide cover. A lower chamber is located below the upper chamber, containing the filter material body. An electric push rod is located below the lower chamber. Flow sensors are located on both the left and right sides below the material tank, and solenoid valves are located below the flow sensors, with a Y-shaped tube fixed to the lower end of the solenoid valves. This utility model uses a motor to rotate the bosses, utilizing centrifugal force to evenly distribute the test liquid. Simultaneously, the electric push rod detaches the lower chamber from the upper chamber for easy assembly and disassembly of the filter material body. Furthermore, the cooperation of the solenoid valves and flow sensors enables testing with different test liquids without manual effort.

[0004] However, in existing devices, the test liquid is usually guided by a flow guide when flowing towards the filter material body. However, the test liquid cannot be evenly distributed on the upper wall of the flow guide, resulting in the test liquid not being able to act evenly on the filter material. Furthermore, it is inconvenient to disassemble. Therefore, we propose a high-temperature resistant filter material pore size testing device that can make the liquid act evenly on the filter material.

[0031] This application is described below with reference to the accompanying drawings and specific embodiments:

[0032] Referring to Figures 1-6, this application provides a high-temperature resistant filter material pore size testing device, including a base 100, a detection device body 110 disposed on the top of the base 100, the detection device body 110 including a lower detection device body 111 and an upper detection device body 112, a Y-shaped conduit 120 passing through the top of the detection device body 110, a liquid inlet tank 130 passing through the top of the Y-shaped conduit 120, two liquid inlets 140 being opened on the top of the liquid inlet tank 130, and a separator being disposed on the inner side wall of the lower detection device body 111. The centrifugal mechanism includes a spiral guide vane 210 and a double-layer centrifugal disc 220. A drive mechanism 300 is provided at the bottom of the centrifugal mechanism, which penetrates one side of the base 100. A circular groove is provided on the inner wall of the lower layer 111 of the detection device body, and a clamping mechanism is engaged in the circular groove. A liquid outlet 150 is provided at the bottom of the detection device body 110. A heating plate is provided on the inner wall of the liquid inlet tank 130. An arc-shaped locking block 400 is provided at the top of the lower layer 111 of the detection device body, and a locking groove is provided at the bottom of the upper layer 112 of the detection device body.

[0033] During use, the base 100 has a detection device body 110 on top. The detection device body 110 consists of two layers: a lower detection device body 111 and an upper detection device body 112. The upper detection device body 112 is connected to the lower detection device body 111 by a slot at the bottom and an arc-shaped locking block 400 at the top, which is sealed by a sealing ring. This allows the upper detection device body 112 to be lifted up and separated from the lower detection device body 111 for cleaning after use. The top is connected to the liquid inlet tank 130 through a Y-shaped conduit 120. The lower detection device body 111 has a built-in centrifugal mechanism, a clamping mechanism, and a drive mechanism 300. A circular groove is provided on the side wall for installing the clamping mechanism. The filter material is placed in the middle of the clamping mechanism and fixed. During use, liquid is introduced into the liquid inlet tank 130 through the liquid inlet 140. A heating plate (not shown in the attached diagram) is installed on the inner wall of the inlet tank 130. After the resistance wire inside the heating plate is energized, the liquid is heated and flows through the Y-shaped conduit 120 at the bottom of the inlet tank 130 into the centrifugal mechanism. The spiral guide vanes 210 and the double-layer centrifugal disc 220 in the centrifugal mechanism are driven to rotate by the drive mechanism at the bottom to centrifuge the liquid. Then the liquid flows to the surface of the filter material held by the clamping mechanism for filtration. After passing through the filter material, it is retained at the bottom and flows out from the outlet 150 for recycling. Then, the flow rate data of the outflowing liquid is monitored in real time by the flow meter installed on the outlet 150 at the bottom of the device, and the flow sensor and solenoid valve installed on the Y-shaped conduit 120 control the flow rate of the two liquids. By combining the data from the flow sensor and the flow meter, the retention capacity of the filter material for different liquids is analyzed to determine the pore size of the filter material.

[0034] In some embodiments, the double-layer centrifugal disk 220 includes a perforated disk 221, a conical guide disk 222 is provided at the bottom of the perforated disk 221, a drive mechanism 300 is provided at the bottom of the perforated disk 221, and a spiral guide vane 210 is provided at the top of the perforated disk 221.

[0035] During use, after the liquid is centrifuged by the spiral guide vane 210, it flows to the top of the perforated plate 221 and is centrifuged again to the conical guide plate 222. Then it flows out along the side wall of the conical guide plate 222, so that the liquid flows to the surface of the filter material, making the test results accurate.

[0036] In some embodiments, radial guide grooves 2221 are formed on the inner sidewall of the conical guide plate 222.

[0037] During use, radial guide grooves 2221 are provided on the inner side wall of the conical guide plate 222 to facilitate the flow of liquid, so that it flows out of the orifice plate 221 evenly after centrifugation.

[0038] In some embodiments, the drive mechanism 300 includes a servo motor 310, the output shaft of the servo motor 310 passes through the side wall of the base 100 and is connected to a rotating rod 320, a bevel gear 330 is provided on one side of the rotating rod 320, a bevel gear 340 is meshed on one side of the bevel gear 330, and a rotating rod 350 is provided on the top of the bevel gear 340.

[0039] During use, the drive mechanism 300 includes a servo motor 310. By turning on the servo motor 310, the servo motor 310 drives the rotating rod 320 on one side to rotate. The rotation of the rotating rod 320 drives the bevel gear 330 on one side to rotate. The rotation of the bevel gear 330 drives the bevel gear 340 and the rotating rod 350 on top of the bevel gear 340 to rotate, thereby driving the double-layer centrifugal disk 220 on top of the rotating rod 350 to rotate, thus realizing the centrifugation of the liquid.

[0040] In some embodiments, a three-way valve 900 is provided on the Y-shaped conduit 120.

[0041] During use, a partition is installed inside the liquid inlet tank 130. By rotating the three-way valve 900 on the Y-shaped conduit 120, it is easy to control whether the liquid flows out in a single flow or a mixed flow. This allows for verification of the filtration performance of the filter media in oil, water, and mixed environments, thus meeting the needs of multiple fields.

[0042] In some embodiments, the clamping mechanism includes a first clamping plate 510 and a second clamping plate 520. A bolt 500 is provided at the bottom of the first clamping plate 510, and a rotating wheel 530 is provided at the bottom of the bolt 500. The second clamping plate 520 and the first clamping plate 510 are disposed in a circular groove opened inside the lower layer 111 of the detection device body, and the second clamping plate 520 is located above the first clamping plate 510.

[0043] During use, the bolt 500 can be tightened upwards by rotating the wheel 530. During the tightening process, the first clamp 510 set at the top and the second clamp 520 set above the first clamp 510 are squeezed together to fix the filter material between the first clamp 510 and the second clamp 520. The distance between the first clamp 510 and the second clamp 520 can be controlled by rotating the wheel 530. It is suitable for filter materials of different thicknesses.

[0044] In some embodiments, a spring 600 is provided at the top of the clamping plate 520, and the spring 600 is located between the clamping plate 520 and the top of the circular groove.

[0045] During use, a spring 600 is installed at the top of clamping plate 2 520 to buffer the filter material when clamping it, preventing excessive squeezing between clamping plate 1 510 and clamping plate 2 520, which could damage the filter material.

[0046] In some embodiments, an arc-shaped side plate 700 is rotatably connected to one side of the lower layer 111 of the detection device body, and a handle 710 is provided on one side of the arc-shaped side plate 700.

[0047] During use, an arc-shaped side plate 700 is rotatably connected to one side of the lower layer 111 of the detection device body. The arc-shaped side plate 700 can be opened by pulling the handle 710 to facilitate the replacement of the filter material.

[0048] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. In addition, those skilled in the art can combine and integrate the different embodiments or examples described in this specification.

[0049] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
