Description

Technical Field

[0001] The utility model relates to the technical field of thin film evaporators, in particular to a disassembly and assembly structure of a thin film evaporator. Background Art

[0002] High-efficiency rotary thin film evaporator is a new type of high-efficiency evaporator that can perform falling film evaporation under certain vacuum conditions by forming an "air knife" through the high-speed rotation of a fixed rotating scraper. It has a large heat transfer coefficient, high evaporation intensity, short and adjustable flow time, and is particularly suitable for evaporation and concentration of heat-sensitive materials and high-viscosity materials, as well as solvent removal.

[0003] Existing thin-film evaporators are difficult and inconvenient to disassemble and assemble internal rotating parts. During disassembly, the internal rotating parts rotate along with the core shaft, preventing the gland screws at the shaft ends from being loosened. During installation, the internal rotating parts rotate along with the core shaft, preventing the gland screws at the shaft ends from being effectively tightened. Furthermore, if the gland screws at the shaft ends are not effectively tightened during installation, prolonged operation can cause them to loosen or, in more serious cases, fall off, making the process extremely unsafe. Utility Model Content

[0004] The technical problem to be solved by the utility model is: the utility model provides a disassembly and assembly structure of a thin film evaporator, which can lock the core shaft through process bolts to prevent the core shaft from rotating, thereby facilitating the disassembly and assembly of rotating parts on the core shaft and reducing the rotation and shaking of various parts during transportation.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a disassembly and assembly structure of a thin film evaporator, including a bearing seat, a core shaft is installed in the bearing seat, the left end of the core shaft is connected to the driving component, and the right end is connected to the blade in the evaporation cylinder body, a threaded hole is opened on the bearing seat, and a process hole is opened on the core shaft. When the threaded hole and the process hole are aligned, a process bolt is screwed into the threaded hole, and the lower end of the process bolt extends into the process hole to lock the core shaft.

[0006] Furthermore, in order to ensure that the process bolt can directly lock the core shaft, the lower end of the threaded section of the process bolt is a polished rod section, and the polished rod section extends into the process hole.

[0007] Furthermore, in order to avoid interference between the polished rod segment and the threaded hole, the diameter of the polished rod segment is smaller than the diameter of the threaded segment.

[0008] Furthermore, in order to prevent the polished rod segment from smoothly entering the process hole, the process hole is a through hole or a blind hole, and the aperture of the process hole is greater than or equal to the diameter of the polished rod segment.

[0009] Furthermore, the threaded hole needs to be sealed when the core shaft is working normally. When the process bolt is not installed in the threaded hole, a sealing gasket is provided on the threaded hole, and the threaded bolt is connected to the threaded hole to compress the sealing gasket.

[0010] Furthermore, in order to facilitate the processing of the threaded hole and the installation of the process bolts, the threaded hole is opened in the middle of the upper end surface of the bearing seat.

[0011] Furthermore, in order not to affect the performance of the core shaft, the process hole is opened in the middle of the core shaft.

[0012] Furthermore, the thin film evaporator is connected to the right end of the bearing box.

[0013] Furthermore, in order to support the entire thin film evaporator, a bracket is connected to the lower end of the bearing seat.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The disassembly and assembly structure of the thin film evaporator of the utility model fixes the core shaft by inserting the process bolts into the process holes to prevent the core shaft from rotating freely. When disassembling and assembling the internal rotating parts, the core shaft can be prevented from rotating together. At the same time, the random rotation and shaking of the main components can be reduced during transportation.

[0016] 2. The disassembly and assembly structure of the thin film evaporator of the utility model can seal the process hole with a sealing gasket and bolts when the core shaft is working normally, so as to prevent debris and dust from entering the interior of the bearing box.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0023] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0024] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0025] like Figure 1 The figure shows a thin-film evaporator assembly and disassembly structure, comprising a bearing housing 1, within which is mounted a core shaft 2, which is connected to the rotating shaft within the bearing housing 1. The left end of the core shaft 2 is connected to a drive component, and the right end is connected to the paddles within the evaporation cylinder 3. A bracket is connected to the lower end of the bearing housing 1, providing support for the entire evaporator. The evaporation cylinder 3 is connected to the right end of the bearing housing.

[0026] A threaded hole 11 is provided on the bearing seat 1, and the threaded hole 11 is provided in the middle of the upper end surface of the bearing seat 1. It is convenient to directly form the threaded hole 11 on the upper end of the bearing seat 1 during processing, and the bolt 5 or the process bolt 6 can also be quickly disassembled and assembled in the later stage.

[0027] A process hole 21 is formed on the mandrel 2. The process hole 21 is axially located at the same position as the threaded hole 11 and is also formed in the middle of the mandrel 2. The process hole 21 can be selectively configured as a through hole or a blind hole according to the application requirements. The depth of the blind hole is approximately 2 / 3-3 / 4 of the diameter of the mandrel 2, which ensures that the process bolt 6 effectively locks the mandrel 2.

[0028] like Figure 2 As shown, the threaded hole 11 needs to be sealed when the core shaft 2 is working normally. A sealing gasket 4 is also provided on the threaded hole 11. The threaded hole 11 is internally threaded with a bolt 5 to compress the sealing gasket 4. The sealing gasket 4 is pressed against the bearing seat 1 by the bolt 5 to prevent the threaded hole 11 from being sealed by the bolt 5 and the sealing gasket 4, thereby preventing foreign matter such as dust and impurities from entering the interior of the bearing box and affecting normal operation.

[0029] When it is necessary to disassemble the internal components of the equipment, first unscrew the bolt 5 and then remove the sealing gasket 4. When the threaded hole 11 is aligned with the process hole 21, screw the process bolt 6 into the threaded hole 11, and extend the lower end of the process bolt 6 into the process hole 21 to lock the core shaft 2.

[0030] The middle part of the process bolt 6 is a threaded section 61 so that the process bolt 6 can be tightened in the threaded hole 11. The lower end of the threaded section 61 is a polished rod section 62, which is inserted into the process hole 21 to lock the core shaft 2.

[0031] In this embodiment, the threaded hole 11 and the process hole 21 have the same diameter. The diameter of the polished rod section is smaller than the diameter of the threaded section. This ensures that the polished rod section can smoothly enter the process hole 21 while the process bolt 6 is screwed into the threaded hole 11, and the polished rod section does not interfere with the threaded hole 11 or the process hole 21.

[0032] In summary, the disassembly and assembly structure of the thin film evaporator of the present invention can lock the core shaft through process bolts to prevent the core shaft from rotating, thereby facilitating the disassembly and assembly of rotating parts on the core shaft and reducing the rotation and shaking of various parts during transportation.

[0033] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of this utility model. The technical scope of this utility model is not limited to the content of the specification and must be determined according to the scope of the claims.
