Description

Technical Field

[0001] This utility model belongs to the field of diaphragm pump technology, and specifically relates to a novel diaphragm pump housing connection structure. Background Technology

[0002] As a fluid transport device widely used in industries such as chemical engineering and alumina, the connection structure of the power end housing, a core component of diaphragm pumps, plays a crucial role in the stability and reliability of the equipment.

[0003] In traditional diaphragm pump power end housing connections, longitudinal bolts are commonly used to connect the I-beam intermediate bearing cap to the intermediate thick plate of the housing. However, this traditional structure has revealed numerous problems in practical use, limiting the improvement of diaphragm pump performance: First, manufacturing is difficult, the parts have complex shapes and structures, and material waste is common; second, assembly is difficult, as the I-beam intermediate bearing cap must first be placed between two thick plates, then moved laterally into the intermediate thick plate, and finally wedged in place using a tangential key; third, the diaphragm pump experiences complex stress conditions during operation, and the intermediate bearing cap is easily deformed and damaged by lateral tensile forces, reducing connection reliability, affecting production continuity, and increasing maintenance costs and safety risks; finally, the threaded holes of traditional bolts are directly machined into the intermediate thick plate, which can easily cause thread damage during long-term use or bolt disassembly and assembly. Since the intermediate thick plate is a critical load-bearing component of the diaphragm pump, thread damage is difficult to repair, often requiring the replacement of the entire thick plate, resulting in significant economic losses, and downtime for replacement severely impacts production schedules. Utility Model Content

[0004] This invention addresses the aforementioned problems and overcomes the shortcomings of existing technologies by providing a novel diaphragm pump housing connection structure. This invention reduces assembly difficulty, improves the reliability of the connection between the intermediate bearing cap and the intermediate thick plate of the housing, enhances the stability of diaphragm pump operation, and strengthens maintainability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] This utility model provides a novel diaphragm pump housing connection structure, including an intermediate thick plate and an intermediate bearing cover. The intermediate bearing cover is a cuboid structure. The intermediate thick plate has a cuboid groove matching the intermediate bearing cover. The intermediate bearing cover is placed in the cuboid groove. The intermediate bearing cover has a vertical through hole. The intermediate thick plate has a vertical groove corresponding to the vertical through hole. A vertical stud is inserted through the vertical through hole and is secured at the top by a vertical nut. The intermediate bearing cover and the top of the thick plate each have a horizontal through hole corresponding to each other. Horizontal studs are inserted through all the horizontal through holes and secured at both ends by horizontal nuts.

[0007] Furthermore, an installation hole is provided on the side of the intermediate thick plate corresponding to the vertical groove, and a cylindrical stud that mates with the vertical stud is provided from the installation hole into the vertical groove. The end of the vertical stud inserted into the vertical groove is engaged by the cylindrical stud.

[0008] Furthermore, guide grooves are provided on both sides of the top edge of the intermediate bearing cover, and guide keys are connected to the guide grooves by screws. The top of the intermediate thick plate is provided with an installation groove corresponding to the guide key.

[0009] Furthermore, the intermediate thick plate is inclined inside the box.

[0010] Furthermore, the tilt angle is 15° with the horizontal direction of the box.

[0011] The beneficial effects of this utility model.

[0012] This invention reduces the number of parts and the difficulty of part processing, significantly improving production efficiency. The structural design of the intermediate bearing cap and the intermediate thick plate of the housing is more reasonable, reducing material waste caused by part processing errors or damage, thereby improving the utilization rate of the plate material. The improved intermediate bearing cap can be directly inserted vertically into the intermediate thick plate, greatly simplifying the assembly process, reducing assembly difficulty, and improving assembly efficiency. It can effectively reduce the risk of deformation of the intermediate bearing cap, improve the reliability of the connection and the stability of equipment operation. Installation and disassembly are convenient, facilitating daily maintenance and troubleshooting. Attached Figure Description

[0013] To make the technical problems solved, the technical solutions, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] Figure 1 This is a structural schematic diagram of the present invention in its initial state.

[0015] The markings in the diagram are as follows: 1 is the intermediate thick plate, 2 is the intermediate bearing cover, 3 is the cuboid groove, 4 is the vertical stud, 5 is the vertical nut, 6 is the horizontal stud, 7 is the horizontal nut, 8 is the mounting hole, 9 is the cylindrical stud, 10 is the guide groove, 11 is the guide key, and 12 is the mounting groove. Detailed Implementation

[0016] As shown in the accompanying drawings, this embodiment provides a novel diaphragm pump housing connection structure, including an intermediate thick plate 1 and an intermediate bearing cover 2. The intermediate bearing cover 2 is a cuboid structure, which is different from the traditional I-shaped structure, thus reducing the difficulty of parts processing.

[0017] The intermediate thick plate 1 has a cuboid groove 3 that matches the intermediate bearing cover 2. The intermediate bearing cover 2 is placed in the cuboid groove 3. The intermediate bearing cover 2 can be directly inserted vertically into the cuboid groove 3 of the intermediate thick plate 1 relative to the intermediate thick plate 1, which greatly simplifies the assembly process.

[0018] The intermediate bearing cap 2 has a vertical through hole, and the intermediate thick plate 1 has a vertical groove corresponding to the through hole. A vertical stud 4 is installed through the through hole, inserted into the vertical groove, and secured at the top by a vertical nut 5. A mounting hole 8 is provided on the side of the intermediate thick plate 1 corresponding to the vertical groove. A cylindrical stud 9, which mates with the vertical stud 4, is installed from the mounting hole 8 into the vertical groove. One end of the vertical stud 4 inserted into the vertical groove is secured by the cylindrical stud 9. This vertical locking design of the vertical stud 4 and the cylindrical nut replaces the traditional method of directly machining threaded holes in the intermediate thick plate 1 with bolts, thus preventing significant economic losses caused by irreparable damage to the intermediate thick plate 1 due to bolt failure.

[0019] The intermediate bearing cap 2 and the top of the thick plate are respectively provided with transverse through holes. Horizontal studs 6 are installed through all the transverse through holes, and are secured at both ends of the horizontal studs 6 by horizontal nuts 7. By connecting with studs in both the horizontal and vertical directions, the horizontal studs 6 share the lateral tension during the operation of the diaphragm pump, reducing the risk of deformation of the intermediate bearing cap 2, improving the reliability of the connection and the stability of the diaphragm pump operation.

[0020] Guide grooves 10 are provided on both sides of the top edge of the intermediate bearing cover 2. Guide keys 11 are connected to the guide grooves 10 by screws. The top of the intermediate thick plate 1 is provided with a mounting groove 12 corresponding to the guide key 11. Before installing the intermediate bearing cover 2, the guide key 11 is connected to the guide grooves 10 on both sides of the intermediate bearing cover 2. Then, the intermediate bearing cover 2 is placed into the cuboid groove 3 according to the guide grooves 10 and the mounting grooves 12 on the intermediate thick plate 1. This makes the installation more convenient and accurate and reduces the assembly difficulty.

[0021] The intermediate thick plate 1 is inclined within the housing, thus changing the original vertical arrangement of the intermediate bearing cover 2 relative to the housing to an inclined installation. This facilitates the placement of the diaphragm pump crankshaft assembly and shortens the front-to-back dimensions of the housing, resulting in a more compact structure and higher space utilization. Since the angle between the crankshaft assembly and the horizontal direction of the housing is approximately 15°, the optimal inclination angle between the intermediate thick plate 1 and the intermediate bearing cover 2 is 15° relative to the horizontal direction of the housing.

[0022] It is understood that the above specific description of this utility model is only used to illustrate this utility model and is not limited to the technical solutions described in the embodiments of this utility model. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of this utility model.
