Description

Technical Field

[0001] The utility model belongs to the field of air separation devices, and is particularly designed to be a sand filling device for a separation box. Background Art

[0002] The fractionating towers and heat exchangers in air separation units operate at ultra-low temperatures, reaching as low as -196°C. Therefore, these cryogenic devices and the connected piping must be placed in an insulated cold box filled with pearlescent sand. To ensure reliable cold box operation and prevent flange leaks from causing sand removal throughout the air separation cold box, the flange connection is often placed in a small compartment. In the event of a flange leak, simply open the compartment's sand removal port to remove the sand, completing the inspection.

[0003] In the prior art, the sand filling holes of the partition boxes of air separation devices are often circular and placed in the middle of the top of the partition box, resulting in incomplete filling of pearl sand at the top of the partition box, which cannot form a good cold preservation effect, causing the cold box to freeze, thereby increasing the energy consumption of the device. Utility Model Content

[0004] The purpose of the utility model is to provide a sand filling device for a partition box to solve the problem in the prior art that pearlescent sand is not filled solidly at the top two corners of an air separation device, resulting in poor cooling effect and high energy consumption.

[0006] A sand filling device for a partition box comprises a sand injection pipe which is arranged through the top side wall of the partition box; the sand injection pipe is close to a corner of the partition box.

[0007] The top of the sand injection pipe is open and arranged upward; there is an angle between the sand injection pipe and the side wall of the partition box, and the top of the sand injection pipe is detachably provided with a matching sealing cover plate.

[0008] The utility model also has the following features:

[0009] Furthermore, the sand injection pipe is formed by fixing and sealing two trapezoidal plates and two rectangular plates;

[0010] The two trapezoidal plates respectively constitute the two side walls of the sand injection pipe, and the two rectangular plates respectively constitute the upper wall and the lower wall of the sand injection pipe.

[0011] Furthermore, the sealing cover plate is provided with a plurality of first threaded holes.

[0012] The sand injection pipe and the sealing cover plate are detachably connected via connecting plates having the same number as the first threaded holes;

[0013] The connecting plate is L-shaped, one part of which is fixedly connected to the side wall of the sand injection pipe, and the other part of the connecting plate is provided with a through hole, into which a connecting bolt matching the first threaded hole can be inserted.

[0014] Furthermore, a handle is provided on the sealing cover.

[0015] Furthermore, a portion of the connecting plate is welded to the side wall of the sand injection pipe.

[0016] Furthermore, a matching sealing gasket is provided at the connection between the sand injection pipe and the sealing cover plate.

[0017] Compared with the prior art, the present invention has the following technical effects:

[0018] The sand filling device for the partition box of the utility model injects pearl sand into the interior of the partition box through the sand injection pipe when in use, which can make the pearl sand in the partition box easy to be filled densely, improve the cold preservation effect while reducing the overall energy consumption, and can also reduce the amount of manual work, and is suitable for large-scale use and promotion in industry. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 It is a schematic diagram of the overall structure of the sand filling device for the partition box of the present invention.

[0020] The meanings of the numbers in the figure are: 1. sand injection pipe; 101. trapezoidal plate; 102. rectangular plate; 2. sealing cover plate; 3. connecting plate; 4. handle; 5. sealing gasket. DETAILED DESCRIPTION

[0021] It should be noted that all components of the present invention, unless otherwise specified, are components known in the prior art. For example, the handle is a commonly used handle.

[0022] The following are specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments, and all equivalent modifications made on the basis of the technical solution of this application fall within the scope of protection of the present invention.

[0023] A sand loading device for a partition box, such as Figure 1 As shown, it includes a sand injection pipe 1 that is set through the top side wall of the partition box; the sand injection pipe 1 is close to a corner of the partition box;

[0024] The opening of the sand injection pipe 1 is upwardly arranged and there is an angle between the sand injection pipe 1 and the side wall of the partition box. A matching sealing cover plate 2 is detachably provided on the top of the sand injection pipe 1 .

[0025] When in use, the pearl sand is injected into the partition box through the sand injection pipe 1, which can make the pearl sand in the partition box easily packed densely, improve the cold preservation effect while reducing the overall energy consumption, and can also reduce the amount of manual work, which is suitable for large-scale use and promotion in industry.

[0026] Specifically, the sand injection pipe 1 is formed by fixing and sealing two trapezoidal plates 101 and two rectangular plates 102 .

[0027] The two trapezoidal plates 101 respectively constitute two side walls of the sand injection pipe 1 , and the two rectangular plates 102 respectively constitute the upper wall and the lower wall of the sand injection pipe 1 .
