[0023] The present invention is further described in detail below in conjunction with the embodiments:

[0024] like Figures 1-5As shown in the figure, the utility model provides a device for testing the flexural strength of a ceramic filter tube, which includes a ceramic filter tube support frame 21 and a ceramic filter tube main body 11. A filter tube fixing mechanism 2 is arranged at the top of the ceramic filter tube support frame 21, and a filter tube breaking tensile force measuring mechanism 3 is arranged in the middle and lower part of the ceramic filter tube support frame 21. The filter tube fixing mechanism 2 includes a flower plate 22 and a pressing plate 26. The flower plate 22 is movably connected to the top of the ceramic filter tube support frame 21. The ceramic filter tube support frame 21 is fixedly installed on the top of a support base plate 1. A flower plate fixing part 23 is movably connected to the top of the flower plate 22. The flower plate fixing part 23 is detachably connected to the top of the ceramic filter tube support frame 21. A ceramic fiber washer 24 is movably connected to the top of the flower plate 22. The ceramic filter tube main body 11 is movably connected to the top of the ceramic fiber washer 24. The outer wall of the ceramic filter tube main body 11 is movably connected to the hole wall of the flower plate 22 with a certain movement gap. A Venturi tube 25 is movably inserted into the top of the ceramic filter tube main body 11. The top of the Venturi tube 25 is movably connected to a pressing plate 26. A fastening bolt 27 is movably connected to the top of the pressing plate 26. A fixed-distance sleeve is movably connected between the pressing plate 26 and the flower plate 22. The flower plate 22, the fixed-distance sleeve, and the pressing plate 26 are connected into one body through the fastening bolt 27. When positioning the ceramic filter tube main body 11, pass the bottom of the ceramic filter tube main body 11 through the ceramic fiber washer 24, and then insert it into the inner cavity of the flower plate 22. Immediately install the Venturi tube 25 and the pressing plate 26 in sequence above the ceramic filter tube main body 11. Then, the verticality of the ceramic filter tube main body 11 can be adjusted by adjusting the tightening degree of the fastening bolt 27, thereby ensuring that the ceramic filter tube main body 11 is completely vertical. The designed height of the ceramic filter tube support frame 21 can meet the flexural strength tests of ceramic filter tubes of different specifications.

[0025] Further, as Figures 1-5As shown in the figure, the filter tube breaking tensile force measuring mechanism 3 includes a pushing support 31 and a pull ring sleeve 36. The pushing support 31 is fixedly installed on the top of the support bottom plate 1 and is located on one side of the ceramic filter tube support frame 21. An arc-shaped component 32 is fixedly installed on the side of the pushing support 31 that contacts the ceramic filter tube body 11. A base 33 is fixedly installed on the side of the pushing support 31 close to the ceramic filter tube body 11. A support plate 34 is slidably connected to the top of the base 33. A lead screw 37 is threadedly connected to the column of the pushing support 31. A hand wheel 39 is fixedly installed on one side of the lead screw 37. A receiving sleeve 38 is rotatably connected to the outer wall on the other side of the lead screw 37. The receiving sleeve 38 is fixedly installed on the top of the vertical plate of the support plate 34. A tensile force gauge 35 is fixedly installed on the flat top of the support plate 34. The pull ring sleeve 36 is movably sleeved on the outer wall of the ceramic filter tube body 11. The measuring end of the tensile force gauge 35 is movably connected to the other end of the pull ring sleeve 36. By manually rotating the hand wheel 39, the lead screw 37 can be driven to rotate simultaneously. Through the design of the threaded connection between the pushing support 31 and the lead screw 37, the lead screw 37 is forced to rotate and displace to the right. Then, driven by the receiving sleeve 38, the support plate 34 slides to the right on the top of the base 33. Thus, the function of gradually stretching the tensile force gauge 35 can be realized, which is convenient for the anti-bending strength test work.

[0026] Next, the working principle of the ceramic filter tube anti-bending strength test device will be specifically described.

[0027] As Figures 1-5 shown in the figure, first, the ceramic filter tube body 11 is positioned. The bottom of the ceramic filter tube body 11 is passed through the ceramic fiber washer 24, and then it is inserted into the inner cavity of the perforated plate 22. Immediately afterwards, the Venturi tube 25 and the pressing plate 26 are successively installed above the ceramic filter tube body 11. Then, by adjusting the tightening degree of the fastening bolt 27, the verticality of the ceramic filter tube body 11 is adjusted. At this time, the outer wall of the ceramic filter tube body 11 is in contact with the left side of the arc-shaped component 32. Subsequently, the pull ring sleeve 36 is sleeved on the outer wall of the ceramic filter tube body 11, and the installation height of the pull ring sleeve 36 is adjusted so that the measuring end of the tensile force gauge 35 connected thereto is horizontally stressed. Then, the filter tube length L between the arc-shaped component 32 and the pull ring sleeve 36 is measured and recorded. Subsequently, the hand wheel 39 is rotated to adjust the position of the tensile force gauge 35 so that the measuring end of the tensile force gauge 35 is horizontally stressed and the tensile force value is zero. The hand wheel 39 is rotated again to cause the tensile force gauge 35 to displace away from the ceramic filter tube body 11 until the filter tube breaks. The tensile force value F of the tensile force gauge 35 at this time is recorded. Subsequently, the anti-bending strength of the ceramic filter tube can be calculated through the distance L and the tensile force value F.

[0028] It should be noted that in the description of the present disclosure, unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0029] The above has generally described the present utility model in detail, but based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
