[0046] The specific implementation of the utility model will be described below in combination with the drawings.

[0047] Example one:

[0048] As shown in the drawing, Figures 1-4 The split sealing groove of the embodiment includes an inner ring 43, a first side wall 431, an outer ring 2, and a second side wall 251.

[0049] The inner ring 43 is arranged on the end face flange 4 of the cleaning tank 5;

[0050] The first side wall 431 is located on the outer circumferential surface of the fixed inner ring 43.

[0051] The outer ring 2 is located outside the inner ring 43 and concentric with the inner ring 43. The outer ring 2 includes a plurality of sections 21, and each section 21 can be detachably mounted on the end face flange 4.

[0052] The second side wall 251 is located on the section 21. A plurality of second side walls 251 are arranged opposite and spaced apart from the first side wall 431. The first side wall 431, the second side wall 251, and the end face flange 4 form a sealing groove for mounting a limiting sealing ring 3.

[0053] The cross section of the cleaning tank 5 can be circular as shown in the drawing, Figure 1 The shape of the sealing groove is adapted to the cross section of the cleaning tank 5.

[0054] The sealing groove is matched with the sealing ring 3, which limits the sealing ring 3 inside the sealing groove. After the tank cover 1 of the cleaning tank 5 covers the tank opening of the cleaning tank 5 and presses on the sealing ring 3, the sealing ring 3 deforms inside the sealing groove, and the tank cover 1 and the cleaning tank 5 form a closed cavity.

[0055] As shown in the drawing, Figure 2 The cross section of the sealing ring 3 is circular, the cross section of the sealing groove is dovetail-shaped, and the first side wall 431 and the second side wall 251 are tangent to the sealing ring 3.

[0056] The dovetail-shaped sealing groove limits the sealing ring 3 from both the inner ring and the outer ring of the sealing ring 3.

[0057] In another embodiment, as shown in Figure 3 the cross section of the sealing ring 3 is circular, and the cross section of the sealing groove is a right-angled trapezoid, the first side wall 431 corresponds to the waist of the right-angled trapezoid with the bottom angle of ninety degrees, and the first side wall 431 and the second side wall 251 are tangent to the sealing ring 3.

[0058] The limiting effect of the right-angled trapezoidal sealing groove on the sealing ring 3 is mainly located at the outer ring position of the sealing ring 3.

[0059] The split sealing groove of the present embodiment, when installing the sealing ring 3:

[0060] First, the sealing ring 3 is sleeved on the outer circumferential surface of the inner ring 43;

[0061] Then, a plurality of segments 21 are installed on the end face flange 4 at a time, and the segments 21 form the sealing groove with the inner ring 43 while limiting the sealing ring 3 in the sealing groove.

[0062] The number of segments 21 is greater than or equal to four.

[0063] As shown in Figure 4 when the cross section of the cleaning tank 5 is circular, the number of segments 21 is four and is evenly divided, and during the installation of the segments 21, two opposite segments 21 can be installed at the same time, which facilitates the balanced limiting of the entire sealing ring 3.

[0064] For the inner diameter size of the cleaning tank 5, if a complete material is used to make the outer ring 2, not only the material cost is high, but also the outer ring 2 is prone to deformation during processing, which causes the size precision of the sealing groove to not meet the requirements. The material of the outer ring 2 is usually stainless steel, which is subjected to deformation such as stretching, twisting, and compression during processing, and the deformation amount reaches 0.2% to 0.5%, which is more difficult for high sealing requirements.

[0065] The outer ring 2 of the present embodiment is divided into a plurality of segments 21, which facilitates single assembly and also reduces the deformation amount of the material during processing.

[0066] The sealing groove is preferably in the shape of a dovetail, which is more convenient for the sealing ring 3 to deform after being pressed.

[0067] By detachably installing a plurality of segments 21 on the end face flange 4 of the cleaning tank 5, the inner ring 43 on the end face flange 4 is enclosed to form a sealing groove, and the outer ring 2 provided in segments facilitates the installation and removal of the sealing ring 3, while saving materials and reducing processing difficulty.

[0068] Embodiment two:

[0069] In order to facilitate the installation and adjustment of the segments 21, as shown in Figures 4-8As shown, the end flange 4 of the split sealing groove in this embodiment is provided with a threaded hole 44, and the segment 21 is provided with a countersunk hole 23 corresponding to the threaded hole 44.

[0070] The countersunk hole 23 has an oblong shape, and the cross-sectional length of the oblong hole is consistent with the radial direction of the outer ring 2.

[0071] The countersunk hole 23 with a waist-shaped hole structure allows the distance between the segment 21 and the inner ring 43 to be adjusted during the installation of the segment 21, thereby adjusting the width of the sealing groove at the corresponding position. This makes the contact limiting effect between the second side wall 251 and the sealing ring 3 adjustable, so as to ensure the sealing effect of the sealing ring 3 while fixing its position.

[0072] Furthermore, such as Figure 7 As shown, a reserved hole 22 is provided on the segment 21 on one side of the countersunk hole 23. After the threaded hole 44 fails after multiple disassemblies of the segment 21, the threaded hole 44 is re-machined on the end face flange 4. The reserved hole 22 facilitates the fitting with the new threaded hole 44.

[0073] like Figure 2 , Figure 5 , Figure 6 As shown, the structure of the end flange 4 includes a flange body 41. One side of the flange body 41 is connected to the cleaning tank 5. An inner ring 43 is provided on the other side of the flange body 41. It also includes an annular boss 42 located outside the inner ring 43. The annular boss 42 is concentric with the inner ring 43. The inner ring 43, the annular boss 42 and the flange body 41 are stepped.

[0074] The first sidewall 431, the second sidewall 251, and the annular boss 42 form a sealing groove, and the flange body 41 is detachably connected to the segment 21.

[0075] Typically, the flange body 41, annular boss 42, and inner ring 43 on the end face flange 4 are integrally machined.

[0076] An annular boss 42 is provided between the installation position of segment 21 and the inner ring 43 to facilitate the positioning and limiting of segment 21 during installation, thereby reducing the difficulty of operation for operators.

[0077] like Figure 2 , Figure 8 As shown, segment 21 includes an arc-shaped body 211. A flange 25 is provided at one end of the inner sidewall of the arc-shaped body 211. A second sidewall 251 is located on the flange 25. The inner sidewall of the arc-shaped body 211 is located outside the annular boss 42. There is a first gap 6 between the inner sidewall of the arc-shaped body 211 and the annular boss 42.

[0078] The first gap 6 is set to match the countersunk hole 23 of the waist-shaped hole structure, which facilitates the adjustment of the width of the sealing groove, limits the minimum value of the sealing groove width, and avoids excessive pressure on the sealing ring 3 by the second side wall 251.

[0079] Example 3:

[0080] When the temperature is high during cleaning or drying in the cleaning tank 5, the sealing ring 3 expands due to heat. To avoid insufficient expansion clearance in the mounting groove, based on the above embodiments, such as... Figure 9 As shown, in this embodiment, the gap between adjacent segments 21 of the split sealing groove is the second gap 24, and the ratio of the diameter of the sealing ring 3 to the width of the second gap 24 is 50 to 100.

[0081] The preferred number of segments 21 is greater than or equal to six, and they are equally divided. A second gap 24 is set at adjacent segments 21 to reserve elastic deformation space for the expansion of the sealing ring 3 when the space in the sealing groove is insufficient, without affecting the limiting effect on the sealing ring 3.

[0082] like Figure 9 As shown, the second sidewall 251 has arc-shaped chamfers 252 at both ends along its length. This is to prevent the ends of the second sidewall 251 from creating indentations on the surface of the sealing ring 3, or even damaging the sealing ring 3.

[0083] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
