Description

Technical Field

[0001] The utility model relates to the technical field of composite floors, and particularly to a horizontal splicing plate type design structure of an air separation cold box. Background Technique

[0002] During the refrigeration work of the air separation unit, the air separation cold box mainly consists of a steel shell insulation box and an internal core aluminum plate-fin heat exchanger. At the same time, considering that the cold box structure is a high-rise structure with a very large aspect ratio, the air separation cold box can adopt a horizontal splicing plate type design structure during the installation process, enabling the assembly and erection to be completed in a short time, meeting the requirements of rapid production, and greatly shortening the installation time.

[0003] In the prior art, when constructing and erecting the air separation cold box using the horizontal splicing plate structure, generally after the left and right box body plates at the top are spliced together, bolt fixation is required. However, considering that during the refrigeration process of the air separation unit, a good sealing environment needs to be maintained, the setting of gaps still existing at the splicing of the cold box after bolt fixation often leads to the problem that during the actual operation of the entire cold box structure, cold air is likely to diffuse outward and affect the refrigeration effect. Content of the Utility Model

[0004] The purpose of the utility model is to provide a horizontal splicing plate type design structure of an air separation cold box to solve the problem that in the prior art, when constructing and erecting the air separation cold box using the horizontal splicing plate structure, the subsequent refrigeration effect is affected due to gaps existing after splicing.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A horizontal splicing plate type design structure of an air separation cold box includes a left horizontal splicing box frame. A right horizontal splicing box frame is adjacent to one side of the left horizontal splicing box frame. Grooves are respectively opened at the upper left of the right horizontal splicing box frame and the upper right of the left horizontal splicing box frame. A group of adjacent grooves are connected by a central card member. A retaining tile is fixedly connected to the top of the central card member. Two card strips are provided on both sides of the bottom of the central card member and are arranged in a left-right symmetric structure. A second sealing pad is adjacent to one side of the card strip close to the vertical end of the central card member. A first density pad is adjacent to one side of the card strip far from the vertical end of the central card member. Third sealing pads are respectively bonded to both sides of the bottom of the retaining tile.

[0007] Preferably, the outer shapes of the left horizontal splicing box frame and the right horizontal splicing box frame are respectively arranged in an "L" shape structure, and the top end faces of the right horizontal splicing box frame and the left horizontal splicing box frame are respectively attached to a group of the third sealing pads.

[0008] Preferably, webs are respectively fixedly connected to the bottoms of the left horizontal splicing box frame and the right horizontal splicing box frame, and fastening round holes are opened on the top end faces of the webs.

[0009] Preferably, the upper half of the retaining tile is arranged in a conical structure, and the retaining tile is arranged directly above the splicing position of the left horizontal splicing box frame and the right horizontal splicing box frame.

[0010] Preferably, the second gasket and the first density pad are adhesively connected to the central card member respectively. The central card member is arranged in a "T" - shaped structure. A card slot engaged with the card strip is connected to the bottom of the groove. The height of the card strip is less than the height of the vertical end of the central card member. The outer surfaces of the second gasket and the first density pad are respectively attached to the inner surface of the groove.

[0011] Compared with the prior art, the beneficial effects of the present utility model are:

[0012] In the present utility model, through the arrangement of the central card member, the first density pad, the card slot, the card strip, the second gasket and the third gasket, it is convenient for the horizontal - splicing plate - type design structure of the air separation cold box to carry out splicing and building operations on the top structure. Under the auxiliary clamping and limiting action of the groove and the card slot, using the sealing structure composed of the central card member, the first density pad, the card slot, the card strip, the second gasket and the third gasket, effective sealing treatment is carried out on the splicing position. At the same time, this sealing structure can avoid gaps at the splicing position after the air separation cold box structure is spliced, and the effective sealing treatment measure can prevent the problem of cold air diffusing outward and affecting the refrigeration effect during the subsequent operation of the air separation device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-3 , the present utility model provides a technical solution:

[0019] A horizontally assembled plate - type design structure for an air separation cold box, comprising a left horizontally assembled box frame 1. Adjacent to one side of the left horizontally assembled box frame 1 is a right horizontally assembled box frame 2. Grooves 4 are respectively opened at the upper left of the right horizontally assembled box frame 2 and the upper right of the left horizontally assembled box frame 1. Between an adjacent set of grooves 4 is connected by a central clamping member 5. A retaining tile 3 is fixedly connected to the top of the central clamping member 5. On both sides of the bottom of the central clamping member 5 are provided two card strips 8 arranged in a left - right symmetric structure. Adjacent to one side of the card strip 8 close to the vertical end of the central clamping member 5 is a second sealing pad 9. Adjacent to one side of the card strip 8 far from the vertical end of the central clamping member 5 is a first density pad 6. On both sides of the bottom of the retaining tile 3 are respectively bonded with third sealing pads 10.

[0020] As Figure 1 and Figure 3 shown, the outer shapes of the left horizontally assembled box frame 1 and the right horizontally assembled box frame 2 are respectively arranged in an "L" - shaped structure. The top end faces of the right horizontally assembled box frame 2 and the left horizontally assembled box frame 1 are respectively in contact with a set of third sealing pads 10. After the right horizontally assembled box frame 2 and the left horizontally assembled box frame 1 are respectively in contact with the third sealing pads 10, this setting can prevent rainwater from penetrating into the interior of the air separation cold box structure through the splicing joint; the bottoms of the left horizontally assembled box frame 1 and the right horizontally assembled box frame 2 are respectively fixedly connected with webs 11. The top end faces of the webs 11 are provided with fastening round holes 12. The webs 11 with fastening round holes 12 mainly play the role of transferring the splicing structure of the lower air separation cold box.

[0021] As Figure 1 , Figure 2 and Figure 3 shown, the upper half of the retaining tile 3 is arranged in a conical structure. The retaining tile 3 is arranged directly above the splicing joint of the left horizontally assembled box frame 1 and the right horizontally assembled box frame 2. The setting of the retaining tile 3 can play an auxiliary role in rain shielding at the top from the splicing joint after the top - base splicing of the entire air separation cold box is built; the second sealing pad 9 and the first density pad 6 are respectively adhesively linked to the central clamping member 5. The outer shape of the central clamping member 5 is arranged in a "T" - shaped structure. At the bottom position of the groove 4 is connected with a card slot 7 that is snap - fitted with the card strip 8. The height of the card strip 8 is less than the height of the vertical end of the central clamping member 5. The outer surfaces of the second sealing pad 9 and the first density pad 6 are respectively in contact with the inner surface of the groove 4. When installing the sealing structure, there is a snap - fit between the card slot 7 and the card strip 8.

[0022] Workflow: When it is necessary to construct and build an air separation cold box with an overall tall structure, the lower foundation structure of the tall structure is mainly horizontally spliced and fixed from bottom to top by multiple groups of left horizontal splicing box frames 1 without tops and right horizontal splicing box frames 2, and gradually built up. When it is necessary to splice and build the top of the entire air separation cold box structure, after the left horizontal splicing box frame 1 and the right horizontal splicing box frame 2 are respectively fixedly connected to the lower horizontal splicing foundation through the lower webs 11, the left horizontal splicing box frame 1 and the right horizontal splicing box frame 2 as the top structures can complete the horizontal splicing and building. At the same time, before using external fastening clips to splice and fasten the left horizontal splicing box frame 1 and the right horizontal splicing box frame 2, the center clip 5 and a group of clip strips 8 can be sequentially pushed into the inside of the groove 4 and the card slot 7 from front to back. While enabling the three to be simultaneously connected to the left horizontal splicing box frame 1 and the right horizontal splicing box frame 2 to play a role in splicing pre-limitation, the third sealing gasket 10 that fits the top surfaces of the left horizontal splicing box frame 1 and the right horizontal splicing box frame 2 will jointly fit the first density gasket 6 and the second sealing gasket 9 of the groove 4 from the splicing position to effectively seal the entire air separation cold box structure that is about to complete the top splicing and building, preventing gaps at the splicing from affecting the subsequent refrigeration effect.
