Description

Technical Field

[0001] The utility model belongs to the technical field of thin film evaporator equipment and relates to a bottom bearing support and lubrication flushing structure for a thin film evaporator. Background Art

[0002] In thin-film evaporator applications, high-freezing-point materials have a significant negative impact on the equipment's operational stability. Since the equipment inevitably requires a support structure at the bottom bearing, the structure in this area is inevitably complex. During its downward flow, high-freezing-point materials inevitably fall and adhere to the supports and bearing seats. Due to the material's high freezing point and the relatively low temperature of the bearing area and its supports, it easily condenses at the drop location, rapidly accumulating and compromising smooth material transportation. Furthermore, some material that flows into the bearing system can cause the bearing to seize and experience abnormal wear, thereby shortening its service life. Summary of the Invention

[0003] In view of the above problems, the utility model provides a thin film evaporator bottom bearing support and lubrication flushing structure, which can alleviate the accumulation of materials in the bearing section, thereby effectively extending the service life of the bearing.

[0022] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0023] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts should fall within the scope of protection of the present invention.

[0024] Figure 1-3 The invention comprises a rotor 1, a lower shaft head 1-1, a gland 2, a sealing ring 3, a support 4, a bearing 5, a bearing seat 6, a bearing seat jacket 7, a jacket tube 8, a fastener 9, a container barrel 10, a frame 11, a reduction motor 12, a lubricating liquid inlet pipe N1, a lubricating liquid outlet pipe N2, a flushing liquid inlet pipe N3, a flushing liquid outlet pipe N4, a heat medium inlet N5, a heat medium outlet N6, etc.

[0025] like Figure 1-3 As shown, the utility model is a bottom bearing support and lubrication flushing structure for a thin film evaporator, which mainly focuses on the overall insulation of the support and the bearing seat to prevent high-freezing point materials from condensing and solidifying on the support and in the bearing seat. It is used to process high-freezing point materials. Its structure includes a container barrel 10, and the bearing seat 6 is supported in the inner cavity of the container barrel 10 by a plurality of support members 4. The bearing seat 6 is coaxially arranged with the container barrel 10, and the bottom of the bearing seat 6 is a closed structure.

[0026] The lower shaft head 1-1 of the rotor 1 is inserted into the bearing seat 6 and is positioned and supported by a bearing 5 mounted on the bearing seat 6. The upper end of the bearing 5 is sealed by a sealing structure. The bearing 5 can be a sliding bearing or a rolling bearing.

[0027] Support member 4 has a hollow inner hole that communicates with a corresponding through-hole in bearing seat 6. Support member 4 includes at least two sets of pipes, each with one inlet and one outlet. Specifically, support member 4 comprises at least four pipes, with the two sets of pipes, one inlet and one outlet, forming a lubricating oil pipeline and a flushing pipeline, respectively. The lubricating oil continuously lubricates bearing 5, extending its service life. The flushing pipeline flushes foreign matter (condensate formed by the entry of high-freezing-point materials and other foreign matter caused by wear) from bearing 5, flushing it out of the bearing system and ensuring proper operation of bearing 5. The hollow inner hole of support member 4 can pass both gas and liquid.

[0028] The shape and number of the support members 4 can be adjusted as needed. If the total number is greater than 4, the excess support members can simply serve as support without having to assume the function of liquid and ventilation. The shape of the support members 4 can also be set according to specific needs and does not necessarily have to be tubular.

[0029] Because lubricating and flushing fluids can create low-temperature zones, this solution insulates the bearing system and support components (by providing an insulating jacket) to prevent any material that falls thereon from condensing and accumulating. Specifically, a heating jacket is provided on the outside of the bearing seat 6. The radially outer end of the heating jacket is sealed to the inner wall of the container barrel 10, and the heating jacket has a heat medium inlet N5 and a heat medium outlet N6. During production, the inner ends of the heat medium inlet N5 and heat medium outlet N6 are respectively connected to the side walls of the corresponding jacket tube 8, and the outer ends of both the heat medium inlet N5 and heat medium outlet N6 penetrate the container barrel 10 and extend to the outside of the container barrel 10.

[0030] The heating jacket includes a bearing seat jacket 7 and a jacket tube 8, wherein the bearing seat jacket 7 is covered on the outside of the bearing seat 6, and multiple jacket tubes 8 are fixedly connected to the outside of the bearing seat jacket 7, and one end of the jacket tube 8 is connected to the bearing seat jacket 7, and the other end is sealed and connected to the inner wall of the container cylinder 10, and a jacket tube 8 is sleeved on the outside of each support member 4.

[0031] The sealing structure includes multiple sealing rings 3, which are sequentially mounted on the lower shaft head 1-1 of the rotor 1. The upper ends of the sealing rings 3 are compressed by a gland 2, which is fixed to the upper end of the bearing seat 6 via fasteners 9. The lower ends of the sealing rings 3 are compressed against the bearing 5. The gland 2 restricts upward movement of components within the bearing seat 6, and the fasteners 9 secure the gland 2 to the bearing seat 6. The number and type of sealing rings 3 can be adjusted and combined as needed.

[0032] The support member 4 includes a lubricating liquid inlet pipe, a lubricating liquid outlet pipe, a flushing liquid inlet pipe, and a flushing liquid outlet pipe.

[0033] The axial outer end of the lubricating liquid inlet pipe is connected to the lubricating liquid inlet pipe N1, and the axial outer end of the lubricating liquid outlet pipe is connected to the lubricating liquid outlet pipe N2.

[0034] The axially outer end of the flushing liquid inlet pipe is connected to the flushing liquid inlet pipe N3, and the axially outer end of the flushing liquid outlet pipe is connected to the flushing liquid outlet pipe N4. The lubricating liquid inlet pipe N1, lubricating liquid outlet pipe N2, flushing liquid inlet pipe N3, and flushing liquid outlet pipe N4 are disposed through the container body 10 to introduce external lubricating and flushing liquids into the bearing seat 6.

[0035] A frame 11 is installed on the top of the container cylinder 10, and a reduction motor 12 is installed on the frame 11.

[0036] The upper end of the rotor 1 extends to the outside of the container cylinder 10 and is connected to the output end of the reduction motor 12.

[0037] like Figure 1-3 As shown, during operation, the container body 10 of the present invention contains a high-freezing-point material (the material will solidify even at higher temperatures), and the rotor 1 rotates. Lubricating fluid enters through the lubricating fluid inlet pipe N1, passes through corresponding holes in the support member 4 and the bearing seat 6, and is introduced into the bearing system, improving the working environment of the bearing 5. The lubricating fluid is then discharged through the lubricating fluid outlet pipe N2. The lubricating fluid inlet pipe N1 and the lubricating fluid outlet pipe N2 form a lubrication system that maintains a certain pressure to prevent material from entering the bearing system. When the sealing structure is in operation, it forms a barrier between the material and the lubricating oil. Due to the high pressure within the lubricating fluid system, some overflow occurs, preventing material from entering the bearing system.

[0038] During operation, flushing liquid (which has a cleaning and dissolving effect on materials) is introduced through the flushing liquid inlet pipe N3 to flush and clean the bearing system, preventing the incoming materials from causing abnormal wear on bearing 5 and damaging the working environment of bearing 5. The flushing liquid flows out through the flushing liquid outlet pipe N4. It is important to note that the lubricating liquid pipelines of the lubricating liquid inlet pipe N1 and the lubricating liquid outlet pipe N2 need to be temporarily closed during the flushing task.

[0039] During operation, heat medium at a constant pressure is continuously introduced through the heat medium inlet N5 and discharged through the heat medium outlet N6, thereby insulating and heating the bearing seat 6 and the exterior of the support member 4. This prevents any material that falls onto it from solidifying and allows it to drip smoothly, thus preventing accumulation and blockage.

[0040] The lubricating fluid introduced through the lubricating fluid inlet pipe N1 can reduce its temperature as needed to improve the local operating temperature environment of the bearing. At the same time, due to the presence of the heating jacket, its lower temperature will not affect the transportation of materials.

[0041] Applicability of this utility model: This solution is primarily targeted at thin-film evaporators. It is also applicable to other gas-based equipment (not necessarily thin-film evaporators) where the bearing housing is protected from material immersion and where protection of rotating bearings is required. This solution primarily prevents condensation and accumulation of high-freezing-point materials in the bearings and their supporting areas; it also prevents material from entering the bearing housing to a certain extent, maintaining stable, long-term operation of the bearing system.

[0042] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to examples, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
