Abstract
Description
Technical Field
[0001] This utility model relates to the field of graphite tower technology, and in particular to a negative pressure energy-saving graphite tower. Background Technology
[0002] A graphite tower is a chemical equipment with graphite as its main structural material. It is usually composed of multiple tower sections and can be used to separate different components in a mixture, such as in distillation, absorption, and extraction. It separates substances within the tower by utilizing the differences in their physical properties, such as boiling point and solubility.
[0003] In practical use, existing graphite towers connect two tower sections using bolts and nuts. However, it is difficult to ensure that the tightening force of each bolt is completely consistent during operation. This leads to poor sealing between tower sections. At the same time, vibrations occur inside the tower sections during operation, which can cause the nuts to loosen, affecting the stability of the overall device during operation. To address this issue, we propose a negative pressure energy-saving graphite tower. Utility Model Content
[0004] In view of the shortcomings of the prior art, this utility model provides a negative pressure energy-saving graphite tower, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a negative pressure energy-saving graphite tower, comprising a tower section one and a tower section two, wherein a sealing assembly is provided between the tower section one and the tower section two; the sealing assembly includes several wedge-shaped blocks, each wedge-shaped block being disposed on the lower surface of the tower section one, and each wedge-shaped block being fixedly connected to the lower surface of the tower section one; the upper surface of the tower section two is provided with several wedge-shaped grooves that cooperate with the wedge-shaped blocks, and a sealing gasket is placed inside each wedge-shaped groove; a clamping plate one is provided on the outer wall of the tower section one, and the tower section one is fixedly connected to the clamping plate one; a clamping plate two is provided on the outer wall of the tower section two. The outer wall of the second tower section is fixedly connected to the second clamping plate. The lower surface of the second clamping plate is provided with several magnetically conductive metal sheets, and the lower surface of the second clamping plate is fixedly connected to these sheets. Several bolts are threadedly connected to the outer walls of the first and second clamping plates, with one end of each bolt penetrating both plates. A nut is threadedly connected to the outer wall of each bolt, and a magnetic washer is fitted onto the outer wall of each bolt. The magnetic washer contacts the magnetically conductive metal sheets, and its upper surface has micro-protruding textures. A permanent magnet is installed inside each nut. A positioning component is provided on the outer wall of the wedge-shaped block.
[0006] The tower section is the main body of the device. A vacuum pump is installed inside the tower section, creating negative pressure inside the tower. The tower section is made of high thermal conductivity graphite, which has extremely high thermal conductivity, making the heat exchange process inside the graphite tower more efficient, thus achieving energy savings. The wedge-shaped block at the bottom of tower section one is aligned with the wedge-shaped groove on the surface of tower section two. The sealing gasket inside the wedge-shaped groove deforms under pressure, filling the gap between the wedge-shaped block and the wedge-shaped groove, forming a good seal. The bolts and nuts work together to press the clamping plates on the outer walls of tower section one and tower section two tightly. During the tightening process, the permanent magnet inside the nut makes the nut magnetic. Due to the magnetic attraction, the magnetic nut will fit tightly against the magnetic washer and the magnetically conductive metal sheet. There is a strong magnetic attraction between the magnetic nut and the magnetic washer, and between the magnetic washer and the magnetically conductive metal sheet. This attraction generates an axial preload after the nut is tightened, keeping the threads of the nut and the bolt in close contact, increasing the friction between the threads, and thus preventing the nut from loosening.
[0007] In a preferred embodiment of this invention, the positioning component includes positioning holes, which are respectively formed on the outer wall of the wedge-shaped blocks in the four cardinal directions (north, south, east, and west). Each positioning hole has a slidably connected positioning pin inside, and one end of each positioning pin penetrates the second tower section and extends to the outer surface.
[0008] By creating positioning holes on the outer wall of the wedge-shaped blocks in the four directions of east, west, south, and north, and using positioning pins, tower section one and tower section two can be accurately aligned during installation, preventing the tower sections from shifting or rotating during installation.
[0009] The beneficial effects of this invention are as follows: The wedge block, wedge groove, and sealing gasket ensure a good seal between the two tower sections during connection. A strong magnetic attraction exists between the magnetic nut and the magnetic washer, as well as between the magnetic washer and the magnetically conductive metal sheet. This attraction generates an axial preload after the nut is tightened, ensuring tight contact between the nut's threads and the bolt's threads, increasing friction between the threads, and thus preventing the nut from loosening.
[0010] This invention uses positioning holes on the outer wall of the wedge-shaped blocks in the four directions (east, south, west, and north) and positioning pins to ensure that tower section one and tower section two are accurately aligned during installation, preventing the tower sections from shifting or rotating during installation.

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Example 1
[0020] Please see Figures 1-5A negative pressure energy-saving graphite tower includes a tower section 1 and a tower section 2, with a sealing assembly 3 between the two sections. The sealing assembly 3 includes several wedge-shaped blocks 301, each fixedly connected to the lower surface of the tower section 1. The upper surface of the tower section 2 has several wedge-shaped grooves 302 that cooperate with the wedge-shaped blocks 301, each groove 302 containing a sealing gasket 303. The outer wall of the tower section 1 is provided with a clamping plate 304, which is fixedly connected to the tower section 1. The outer wall of the tower section 2 is provided with a clamping plate 305, which is fixedly connected to the outer wall of the tower section 2. The lower surface of plate 2 305 is provided with several magnetically conductive metal sheets 306. The lower surface of clamping plate 2 305 is fixedly connected to several magnetically conductive metal sheets 306. The outer walls of clamping plate 1 304 and clamping plate 2 305 are threadedly connected with several bolts 307. One end of each bolt 307 passes through clamping plate 1 304 and clamping plate 2 305. The outer wall of each bolt 307 is threadedly connected with a nut 309. The outer wall of each bolt 307 is also fitted with a magnetic washer 308. The magnetic washer 308 contacts the magnetically conductive metal sheets 306. The upper surface of the magnetic washer 308 is provided with micro-protruding textures. A permanent magnet 310 is installed inside each nut 309. The outer wall of the wedge block 301 is provided with a positioning component 4.
[0021] The tower section is the main body of the device. A vacuum pump is installed inside the tower section to create negative pressure inside the tower. The tower section is made of high thermal conductivity graphite, which has extremely high thermal conductivity, making the heat exchange process inside the graphite tower more efficient, thus achieving energy savings. The wedge-shaped block 301 at the bottom of tower section 1 is aligned with the wedge-shaped groove 302 on the surface of tower section 2. The sealing gasket 303 inside the wedge groove 302 deforms under pressure, filling the gap between the wedge-shaped block 301 and the wedge groove 302, forming a good seal. The bolts 307 and nuts 309 work together to secure the clamping plate 304 on the outer wall of tower section 1 and tower section 2. The clamping plate 305 is pressed together. During the tightening of the nut 309, the permanent magnet 310 inside the nut 309 makes the nut 309 magnetic. Due to the magnetic attraction, the magnetic nut 309 will be tightly attached to the magnetic washer 308 and the magnetic metal sheet 306. There is a strong magnetic attraction between the magnetic nut 309 and the magnetic washer 308, and between the magnetic washer 308 and the magnetic metal sheet 306. This attraction will generate an axial preload after the nut 309 is tightened, so that the thread of the nut 309 and the thread of the bolt 307 are in close contact, increasing the friction between the threads, thereby preventing the nut 309 from loosening.
[0022] Please see Figure 2 and Figure 6In this embodiment, the positioning component 4 includes positioning holes 401, which are respectively opened on the outer wall of the wedge-shaped blocks 301 in the four directions of east, west, south and north. Each positioning hole 401 is slidably connected with a positioning pin 402, and one end of each positioning pin 402 passes through the tower section 2 and extends to the outer surface.
[0023] By creating positioning holes 401 on the outer wall of the wedge-shaped blocks 301 in the four cardinal directions (north, south, east, and west), and using positioning pins 402, tower section 1 and tower section 2 can be accurately aligned during installation, preventing displacement or rotation of the tower sections during installation.
[0024] Working principle: Align the wedge block 301 at the bottom of tower section 1 with the wedge groove 302 on the surface of tower section 2. When the wedge block 301 enters the wedge groove 302, insert the four locating pins 402 into the locating holes 401 on the outer wall of the wedge block 301 to prevent the two tower sections from shifting during installation. The sealing gasket 303 inside the wedge groove 302 deforms under pressure, filling the gap between the wedge block 301 and the wedge groove 302 to form a good seal. The engagement of the bolts 307 and nuts 309 presses the clamping plates 304 and 305 on the outer walls of tower section 1 and tower section 2 together. During the tightening process of nut 309, the permanent magnet 310 inside nut 309 makes nut 309 magnetic. Due to the magnetic attraction, magnetic nut 309 will fit tightly with magnetic washer 308 and magnetic metal sheet 306. There is a strong magnetic attraction between magnetic nut 309 and magnetic washer 308, and between magnetic washer 308 and magnetic metal sheet 306. This attraction will generate an axial preload after nut 309 is tightened, so that the thread of nut 309 and thread of bolt 307 are in close contact, increasing the friction between threads, thereby preventing nut 309 from loosening.
[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
