Abstract
Description
Technical Field
[0001] This invention relates to the technical field of lining tanks for refrigeration installation, specifically energy-saving lining tanks. Background Technology
[0002] All polymer bushings for ship rudder systems require cryogenic installation. Currently, new 82,000-ton bulk carriers require dry ice for freezing. During construction, the bushings are placed in a freezing barrel, and the gaps are filled with purchased dry ice for freezing. All types of bearings in the shafting system require freezing before installation. The entire bearing is placed in a freezing barrel, and a large amount of dry ice is added to submerge the entire bearing. After freezing for a period of time, the bearing is removed from the dry ice using a thick steel wire pre-fitted on it, and finally, the bearing is installed in the appropriate position.
[0003] The Chinese invention patent application CN110017636B discloses a freezing barrel and freezing method. While this freezing barrel, after freezing, allows for the use of a lifting plate to suspend the workpiece, avoiding the safety risks associated with the brittle and weakened steel wire after freezing when removing or suspending the workpiece, it suffers from several drawbacks. Firstly, it is difficult to secure the bushing during use, leading to displacement during lifting and potential damage. Secondly, during freezing, the bushing is prone to colliding with the inner wall of the freezing barrel when it moves, causing damage. Thirdly, the excessive gap between the inner wall of the bushing and the inner liner results in wasted dry ice, and the top cover of the freezing barrel is prone to leakage, leading to dry ice loss and potential economic losses. Therefore, an energy-saving inner liner barrel is proposed to address these issues. Summary of the Invention

[0013] (III) Beneficial Effects
[0014] Compared with the prior art, the present invention provides an energy-saving inner lining barrel, which has the following beneficial effects:
[0015] 1. This energy-saving inner liner bucket consists of an inner liner bucket assembly and a sealing cap assembly. The inner liner bucket assembly can be fixed by a limiting groove and a limiting post. When the freezing bucket is moved, the inner liner bucket may shift, causing the bushing to collide with the inner wall of the freezing bucket and be damaged. The bushing is fixed by the support plate and spring on the inner liner bucket assembly to prevent the bushing from falling and being damaged during hoisting. The sealing cap assembly seals the freezing bucket to prevent dry ice leakage and thus prevent certain economic losses. The connecting post allows for better removal of the hoisted bushing from the inner liner bucket assembly for installation.
[0016] 2. This energy-saving inner liner bucket assembly uses a bushing to press against a pressing plate, thereby securing the bushing with the spring force and the inner liner bucket. Ropes are easily inserted at the two connecting rings for hoisting the inner liner bucket. Inserting the connecting post into the arc-shaped groove reduces the gap between the bushing and the inner liner bucket, thus saving dry ice. The connecting post can be easily removed using the fixing ring, facilitating the removal of the bushing from the inner liner bucket assembly. The sealing cap assembly seals the freezing bucket by rotating the sealing cap. Dry ice can be added to the freezing bucket by opening the sealing bag and dry ice inlet. The dry ice inlet is sealed with a threaded cap. The sealing cap assembly is easy to open with a handle. Insulation cotton prevents workers from being frostbitten when opening the sealing cap assembly. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] Please see Figure 1-6 The energy-saving inner liner includes a freezing bucket 1 and an inner liner assembly 3. The inner liner assembly 3 is located on the inner bottom of the freezing bucket 1 through a limiting groove 2. The outer side of the inner liner assembly 3 is provided with a connecting column 4. The top of the connecting column 4 is provided with a fixing ring 5. The top of the freezing bucket 1 is provided with a sealing cap assembly 7 through a slot 6. The top of the sealing cap assembly 7 is provided with a handle 8. The inner liner assembly 3 and the sealing cap assembly 7 are combined to fix the inner liner assembly 3 through the limiting groove 2 and the limiting column 11, preventing the inner liner 301 from shifting when the freezing bucket 1 moves, causing the bushing to collide with the inner wall of the freezing bucket 1 and be damaged. The bushing is fixed by the support plate 302 and the spring 303 on the inner liner assembly 3 to prevent the bushing from falling and being damaged during hoisting. The sealing cap assembly 7 seals the freezing bucket 1 to prevent dry ice leakage and thus prevent certain economic losses. The connecting column 4 allows the bushing to be hoisted out of the inner liner assembly 3 for installation.
[0026] When using, such as Figure 1 As shown, a limiting groove 2 is provided on the inner bottom of the freezing drum 1, and a limiting post 11 is provided in the center of the limiting groove 2. A slot 6 is provided on the top of the outer wall of the freezing drum 1, and a glass window 12 is provided on one side of the outer wall of the freezing drum 1. The limiting post 11 is provided on the inner bottom of the freezing drum 1. The inner liner 301 is connected to the limiting post 11 through a groove. The limiting groove 2 and the limiting post 11 fix the inner liner assembly 3 to prevent the inner liner 301 from shifting when the freezing drum 1 moves, causing the liner to collide with the inner wall of the freezing drum 1 and be damaged. The slot 6 can be used to install the sealing cap assembly 7. The freezing status of the liner and the amount of dry ice added can be observed through the glass window 12 to prevent excessive dry ice from being added and wasted.
[0027] When using, such as Figure 1 and Figure 5 As shown, there are two handles 8. The inside of the handle 8 is equipped with heat insulation cotton 9, and the outside of the handle 8 is covered with a rubber ring 10. The heat insulation cotton 9 can prevent workers from being frostbitten when opening the sealing cover assembly 7, and the rubber ring 10 can increase friction to prevent the sealing cover assembly 7 from slipping and injuring workers.
[0028] When using, such as Figure 1 and Figure 2 As shown, the inner liner assembly 3 includes an inner liner 301, support blocks 302, springs 303, extrusion plates 304, and connecting rings 305. Support blocks 302 are provided around the bottom of the inner liner 301. A spring 303 is located on one side of the inner side of each support block 302, and an extrusion plate 304 is located on one side of each spring 303. A connecting ring 305 is located at the top of the inner liner 301. An arc-shaped groove 13 is provided on the outer side of the freezing drum 1. There are four support blocks 302, each L-shaped. One side of each support block 302 is connected to the extrusion plate 304 via a groove. The connecting ring 305... There are two bushings, with ropes looped between the two connecting rings 305. By squeezing the bushing against the compression plate 304, the bushing is fixed by the elastic force of the spring 303 and the inner liner 301. The inner liner 301 can be easily hoisted out by looping ropes between the two connecting rings 305. Then, inserting the connecting post 4 into the arc groove 13 can reduce the gap between the bushing and the inner liner, thereby saving dry ice. The connecting post 4 can be easily removed by the fixing ring 5, so that the bushing can be easily removed from the inner liner assembly 3, preventing the bushing from falling and being damaged by collision during hoisting.
[0029] When using, such as Figure 3 and Figure 4 As shown, one side of the arc-shaped groove 13 is connected to the connecting post 4. There are four connecting posts 4. The rope can pass through the arc-shaped groove 13 to facilitate the removal of the bushing. The connection between the connecting post 4 and the arc-shaped groove 13 can reduce the gap between the arc-shaped groove 13 and the bushing, thereby saving dry ice.
[0030] When using, such as Figure 5 and Figure 6As shown, the sealing cap assembly 7 includes a fixed cap 701, a knob 702, a dry ice inlet 703, a sealing cap 704, a retaining ring 705, a sealing bag 706, and a threaded cap 707. The sealing cap 704 is threadedly connected to the inner side of the fixed cap 701. The knob 702 is located on the top of the sealing cap 704. The dry ice inlet 703 is located on the top of the sealing cap 704 through a groove. The sealing bag 706 is fitted over the outer side of the dry ice inlet 703. One end of the dry ice inlet 703 is threadedly connected to the sealing cap 704. The retaining ring 705 is located at the bottom of the fixed cap 701. One end of the sealing bag 706 is connected to the dry ice inlet 703, and the other end of the dry ice inlet 703 is secured with a rope. Ring 705 is connected to slot 6. A rubber sealing gasket is provided between fixed cover 701 and sealing cover 704. The intersection of knob 702 is arc-shaped. Sealing cover assembly 7 can seal freezing drum 1 by rotating sealing cover 704. Dry ice can be added to freezing drum 1 by opening sealing bag 706 and dry ice inlet 703. Dry ice inlet 703 can be sealed by threaded cover 707 to prevent dry ice leakage and thus prevent certain economic losses. Then, sealing cover assembly 7 can be opened more easily by handle 8. The intersection of knob 702 is arc-shaped to prevent workers from being scratched when unscrewing knob 702. Sealing bag 706 can better seal dry ice inlet 703.
[0031] In summary, the inner liner assembly 3 and the sealing cap assembly 7 are used to first fix the inner liner assembly 3 by means of the limiting groove 2 and the limiting post 11 to prevent the inner liner 301 from shifting and colliding with the inner wall of the freezing barrel 1 during movement of the freezing barrel 1, which would cause damage. Then, the inner liner assembly 3 fixes the bushing by pressing the bushing against the compression plate 304, thereby fixing the bushing with the elastic force of the spring 303 and the inner liner 301. Ropes are easily inserted into the two connecting rings 305 to hoist the inner liner 301 out. Then, the connecting post 4 is inserted into the arc-shaped groove 13 to reduce the gap between the bushing and the inner liner, thereby saving dry ice. The fixing ring 5 makes it easy to connect the connecting post 4. The bushing is removed to facilitate its removal from the inner liner assembly 3, preventing it from falling and being damaged during hoisting. The freezing drum 1 is then sealed by the sealing cap assembly 7. The sealing cap assembly 7 can seal the freezing drum 1 by rotating the sealing cap 704. Dry ice can be added to the freezing drum 1 by opening the sealing bag 706 and the dry ice inlet 703. The dry ice inlet 703 can be sealed by the threaded cap 707 to prevent dry ice leakage and thus prevent economic losses. The sealing cap assembly 7 can be opened more easily by the handle 8. The insulation cotton 9 can prevent workers from being frostbitten when opening the sealing cap assembly 7. The connecting column 4 can be used to better remove the hoisted bushing from the inner liner assembly 3 for installation.
