Description

Technical Field

[0001] The utility model belongs to the technical field of mass flow meter diverters, and in particular relates to an integrated mass flow meter diverter with internal reinforcing ribs. Background Art

[0002] A mass flowmeter is a metering device used to measure highly viscous media, such as thick, pasty materials. The splitter is the core component of a mass flowmeter. Its main structure consists of a separator housing and splitter pipes mounted on both sides of the separator housing. The splitter pipes are fixed to the housing.

[0003] In the actual production process, the shell of the diverter is easily deformed during installation and use. Specifically, due to the stress of the shell, the shell is deformed during installation, such as welding, and during use, which leads to the technical defect that it is easy to break and tear.

[0004] Therefore, in order to improve the deformation effect of the shell, the prior art adopts a method of integrally casting the shell and the flange. For example, Chinese patent publication number CN 204359374 U discloses a Coriolis mass flowmeter sensor, which forms an integral structure by integrally casting the diverter shell and the flange to improve stability.

[0005] However, in actual operation, it was found that although the one-piece casting method can increase stability, the shell of a large splitter with a large shell area is still prone to deformation during welding and use. Specifically, due to its large area and low tensile strength, the shell of a large splitter can easily tear or deform during welding and use when the shell is subjected to uneven force. This greatly reduces the sealing performance of the shell. Utility Model Content

[0006] Based on the above background, the purpose of the present utility model is to provide an integrated flow divider for a mass flow meter with internal reinforcement ribs.

[0015] Preferably, the left and right ends of the long transverse ribs are respectively fixedly connected with end vertical ribs, and the end vertical ribs are fixedly connected to the inner side wall of the diverter housing;

[0017] The lower rib grooves include, from left to right, a first lower rib groove, a second lower rib groove, and a third lower rib groove.

[0018] Preferably, the compression reinforcement ribs include inner annular ribs and outer annular ribs arranged concentrically;

[0020] Preferably, an external connecting rib structure is welded on the outer side wall of the outer annular rib, and the external connecting rib structure is fixedly connected to the inner side walls of the corresponding upper rib groove and lower rib groove.

[0021] Preferably, the external connecting rib structure includes horizontal external connecting ribs arranged horizontally and inclined external connecting ribs arranged diagonally;

[0022] The horizontal external connecting ribs are fixed by horizontal welding, and the inclined external connecting ribs are fixed by inclined welding.

[0023] Preferably, the middle rib grooves include, from left to right, a first middle rib groove, a second middle rib groove, and a third middle rib groove;

[0025] Preferably, the side end pulling bars include a horizontal pulling bar and two vertical pulling bars perpendicular to the horizontal pulling bar;

[0026] The inner ends of the horizontal reinforcements are fixed on the longitudinal reinforcements.

[0027] Preferably, the diverter housing is fixedly connected with an arc-shaped connecting rib integrally formed between the diverter pipes;

[0033] 2. When the shell's edge is under pressure, the inner and outer annular ribs are designed as a circular structure. Due to the circular structure's greater compressive strength (the circular structure has greater surface tension and is more resistant to compression), it achieves enhanced deformation resistance. Simultaneously, with the cooperation of the external connecting rib structure, the stability of the local tensile and deformation-resistant units is further improved, thus addressing the shell's structural weakness and easy deformation at the edge.

[0034] 3. The left and right edges of the shell are reinforced as a whole through the side tensioning reinforcement, which solves the defect that the left and right sides of the shell are easily formed and torn under pressure.

[0035] The central tensioning ribs include a central rib ring fixedly connected to the edge of the mounting hole, and a plurality of diagonally arranged ribs fixedly connected to the outer wall of the central rib ring. These diagonally arranged ribs strengthen the shell structure from the center. Specifically, the diagonally arranged ribs generate diagonal tension, further preventing deformation and tearing of the shell. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Example 1

[0045] like Figure 1-3The figure shows an integrated mass flowmeter splitter with internal reinforcement ribs. The splitter's main structure is the same as that of existing mass flowmeters, specifically comprising a splitter housing 1 and splitter pipes 111 integrally formed at both ends of the splitter housing 1 by casting. The splitter pipes 111 have flanges 11 at their outer ends for connecting to pipes. The splitter pipes 111 extend through the housing cavity of the splitter housing 1.

[0046] In order to solve the defects of the large-sized diverter shell 1 having weak tensile and deformation resistance during welding and use, the following improvements are made: the integrated mass flow meter diverter with internal reinforcing ribs also includes a reinforcing rib structure fixed inside the diverter shell 1.

[0047] Specifically, the reinforcing rib structure includes two long transverse ribs 22 spaced apart from each other, and two vertically arranged longitudinal ribs 21 are staggered between the long transverse ribs 22 .

[0048] At the same time, the left and right ends of the long transverse rib 22 are respectively fixedly connected with end vertical ribs 221 , and the end vertical ribs 221 are fixedly connected to the inner side wall of the diverter housing 1 .

[0049] Based on this, the long transverse ribs 22, the longitudinal ribs 21 and the upper end of the diverter housing 1 form a plurality of upper rib grooves. Similarly, the compression reinforcement ribs 4 are fixedly connected in the upper rib grooves.

[0050] Specifically, the upper rib groove includes, from left to right, a first upper rib groove 31 (the first upper rib groove 31 is formed by the end vertical rib 221, the inner side wall of the diverter shell 1, the long transverse rib 22, and the longitudinal rib 21), a second upper rib groove 32 (formed by the inner side wall of the diverter shell 1, the long transverse rib 22, and the longitudinal rib 21), and a third upper rib groove 33 (formed by the end vertical rib 221, the inner side wall of the diverter shell 1, the long transverse rib 22, and the longitudinal rib 21).

[0051] Similarly, a plurality of lower rib grooves are formed between the long transverse ribs 22, the longitudinal ribs 21 and the lower end of the diverter housing 1 (similarly, the lower rib grooves are fixedly connected with the compression reinforcement ribs 4).

[0052] The lower rib grooves include, from left to right, a first lower rib groove 34 , a second lower rib groove 35 , and a third lower rib groove 36 (formed in the same manner as the first to third upper rib grooves 31 to 33 ).

[0053] First, during the working process, the long transverse ribs 22 and the longitudinal ribs 21 are welded across the upper, lower, left and right side walls of the diverter shell 1, so that the staggered long transverse ribs 22 and the longitudinal ribs 21 are used as the main pulling and anti-deformation structure. That is, during the working process, when the diverter shell 1 is subjected to vertical or horizontal tension, the long transverse ribs 22 and the longitudinal ribs 21 are used to achieve tensile resistance and prevent deformation.

[0054] Secondly, the compressive reinforcement ribs 4 in the first to third lower rib grooves 34 to 36 and the first to third upper rib grooves 31 to 33 form multiple local tensile and anti-deformation units to address the defect that the edge of the shell is easily deformed after being compressed.

[0055] Specifically, the compressive reinforcement rib 4 comprises a concentrically arranged inner annular rib 42 and an outer annular rib 41. Several annular short connecting ribs 43 are located between the inner and outer annular ribs 42 and 41, and are welded together to secure the inner and outer annular ribs 42 and 41. Furthermore, an external connecting rib structure is welded to the outer wall of the outer annular rib 41 and is fixedly connected to the inner wall of the corresponding upper and lower rib grooves.

[0056] Specifically, the external connecting rib structure includes horizontal external connecting ribs 45 arranged horizontally and diagonally inclined external connecting ribs 44 arranged diagonally. The horizontal external connecting ribs 44 are welded horizontally (with their ends welded to the longitudinal ribs 21 and the end vertical ribs 221, respectively). The inclined external connecting ribs 44 are welded diagonally. The four diagonally arranged inclined external connecting ribs 44 weld the outer annular rib 41 to the diagonal positions of the rib groove, forming a diagonal tensioning structure.

[0057] When the edge of the shell is under pressure, the circular structure of the inner and outer annular ribs 42 and 41 enhances deformation resistance due to the greater compressive strength of the circular structure (the circular structure has a high surface tension and is more resistant to pressure). At the same time, the stability of the local tensile and deformation-resistant units is further improved with the cooperation of the external connecting rib structure, thus avoiding the defect of the shell structure's edge being vulnerable to pressure and easily deformed.

[0058] Example 2

[0059] like Figure 1-3 As shown, in this embodiment, based on the structure of embodiment 1, a plurality of intermediate rib grooves are formed between the long transverse ribs 22 and the longitudinal ribs 21, and tension reinforcement ribs are fixedly connected in the intermediate rib grooves.

[0060] Specifically, the middle rib grooves include the first middle rib groove 37, the second middle rib groove 38 and the third middle rib groove 39 from left to right; the tension reinforcement ribs include side end tension ribs 5 fixedly connected to the first middle rib groove 37 and the third middle rib groove 39 respectively, and a center tension rib fixed in the second middle rib groove 38.

[0061] Similarly, the left and right edges of the shell are locally reinforced by the side tensioning bars in the first middle rib groove 37 and the third middle rib groove 39, and the center tensioning bars locally reinforce the center of the shell.

[0062] Specifically, the side end pulling reinforcement 5 includes a horizontal reinforcement 52 and two vertical reinforcements 51 perpendicular to the horizontal reinforcement 52 ; the inner end of the horizontal reinforcement 52 is fixed on the longitudinal reinforcement 21 .

[0063] The other end (outer end) of the side traction muscle 5 is fixed in the following way:

[0064] An arc-shaped connecting rib A integrally formed between the diverter pipe 111 is fixedly connected inside the diverter housing 1 (the arc-shaped connecting rib A is used to improve the stability between the diverter pipe 111 and the diverter housing 1); the outer end of the horizontal tie bar 52 is welded and fixed to the arc-shaped connecting rib A.

[0065] The above method realizes the integral reinforcement of the left and right edge parts of the shell, thereby solving the defect that the left and right sides of the shell are easily formed and torn under pressure.

[0066] At the same time, similar to the existing diverter housing 1, a mounting hole 12 is installed on the diverter housing 1; the mounting hole 12 is located in the second middle rib groove 38, and the central pulling rib includes a central rib ring 61 fixedly connected to the edge of the mounting hole, and the outer wall of the central rib ring 1 is fixedly connected to a plurality of inclined tension ribs 6 arranged diagonally.

[0067] Similarly, the shell structure is strengthened from the center by the diagonally arranged inclined tie bars 6. Specifically, the diagonally arranged inclined tie bars 6 form a diagonal pulling force, further avoiding the defects of shell deformation and tearing.

[0068] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
