Description

Technical Field

[0001] This utility model relates to the field of motion recognition technology, and in particular to a low-cost assembled spiral stirring conveyor blade structure. Background Technology

[0002] In the wastewater treatment industry, especially in the sludge treatment process, the spiral structures used in sludge mixing and conveying equipment are generally divided into shaftless spirals and shafted spirals. The difference between shaftless spirals and shafted spirals is whether or not they have a central shaft.

[0003] The spiral shape is continuous. Due to the shape of the spiral itself, the processing and manufacturing of any type of spiral is very difficult. Often, a single spiral is very long and requires multiple sections to be welded together. In addition, special processing equipment is required. For general production workshops, outsourcing is often necessary, resulting in high labor costs and long working hours.

[0004] Therefore, how to provide a low-cost assembled spiral mixing conveyor blade structure is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to propose a low-cost assembled spiral mixing and conveying blade structure. This invention solves the problems of high labor costs and long working hours caused by the long length of the spiral blades in the prior art, which require multiple sections to be welded together and require patented processing equipment to assist in processing.

[0006] A low-cost assembled spiral stirring and conveying blade structure according to an embodiment of the present invention includes a main shaft, a locking assembly provided on the surface of the main shaft, and spiral blades provided on the side of the locking assembly.

[0007] The locking assembly includes a mounting hole, a locking screw, a limiting plate, and a locking nut. The mounting hole is opened on the surface of the spindle. The limiting plate is fixedly sleeved on the surface of the locking screw. One end of the locking screw is fixed to the helical blade. The other end of the locking screw passes through the mounting hole and extends to the other side of the mounting hole. The locking nut is threaded onto the surface of the locking screw away from the limiting plate. The limiting plate is movably locked on the surface of the spindle.

[0008] The main shaft is a rectangular shaft.

[0009] The spiral blades are oriented at 90 degrees, and four consecutive spiral blades form a complete spiral assembly.

[0010] The shape of the limiting plate matches the shape of the spindle surface.

[0011] The helical blades are provided with teeth on their sides.

[0012] The beneficial effects of this utility model are:

[0013] By setting up a locking assembly and helical blades, the helical blades are installed on the main shaft through the locking assembly. Four helical blades form a helical group. Several helical groups can be installed as needed, which achieves the effect of quickly installing and removing the helical blades in segments. This solves the problems of high labor costs and long working time caused by the long length of the helical blades in the existing technology, which requires multiple segments to be welded and requires patented processing equipment to assist in processing.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] refer to Figure 1-8 In this embodiment, a spindle 1 is included. A locking assembly 2 is provided on the surface of the spindle 1. The locking assembly 2 includes a mounting hole 4, a locking screw 5, a limiting plate 6, and a locking nut 7. The mounting holes 4 are formed on the surface of the spindle 1, and each mounting hole 4 corresponds to the position of its respective spiral blade 3. The mounting holes 4 are round holes that pass through the spindle 1. The limiting plate 6 is fixedly sleeved on the surface of the locking screw. One end of the locking screw 5 is fixed to the spiral blade 3, and the other end of the locking screw 5 passes through the mounting hole 4 and extends to the other side of the mounting hole 4. The shape of the limiting plate 6 matches the shape of the surface of the spindle 1, so that the limiting plate 6 and the spindle 1 have a higher degree of fit during operation. The limiting plate 6 is "n" shaped, so that it can be stably locked on the surface of the spindle 1 to stabilize the limiting plate 6. The locking nut 7 is threadedly sleeved on the surface of the locking screw 5 away from the limiting plate 6. The spiral blade 3 is fixed. On the surface of the limiting plate 6, the side of the locking assembly 2 is provided with a spiral blade 3. The spiral blade 3 is oriented at 90 degrees. Four consecutive spiral blades 3 form a complete spiral group, dividing a complete spiral group into four pieces. Each spiral blade 3 occupies a 90-degree orientation, which facilitates disassembly and installation. During operation, first insert the locking screw 5 into the mounting hole 4, then clamp the limiting plate 6 on the surface of the main shaft 1 to stabilize the position and orientation of the spiral blade 3. Then, put the locking nut 7 on the surface of the locking screw 5 to fix the locking screw 5 on the main shaft 1. In this way, the spiral blade 3 can be completely fixed. Each spiral blade 3 is installed in the above manner to form a continuous spiral. The operation is simple and does not require multi-segment welding or the use of special processing equipment. The spiral blade 3 can be cut from steel plate, which greatly reduces the processing difficulty of the spiral blade 3.

[0026] refer to Figure 1-8 In this embodiment, the main shaft 1 is a rectangular shaft. The rectangular design can stabilize the position of the limiting plate 6 and improve the stability of the limiting plate 6.

[0027] refer to Figure 1-8 In this embodiment, the side of the spiral blade 3 is provided with teeth 8. The design of the teeth 8 is very ingenious. When the spiral blade 3 rotates, the teeth 8 can drive the stirring capacity to increase, thereby improving the mixing of the required materials.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
