Description

Technical Field

[0001] The utility model relates to the field of industrial heat exchanger manufacturing, in particular to a detachable guard plate structure used for a pipe opening of an evaporative cooler. Background Art

[0002] In metallurgy, petrochemical, coal chemical, polysilicon and other industries, evaporative coolers (condensers) are widely used. Evaporative cooler (condenser) equipment requires regular inspection, maintenance, and replacement of parts. To this end, the outer protective plate of the equipment must be removed before internal operations can be performed. However, the pipe mouth is generally provided with a flange connected to the external medium pipeline, a blow-off sewage pipe assembly, etc. If you want to remove the outer protective plate of the pipe mouth, you must cut the outer protective plate or cut off the medium pipe mouth flange, and blow-off the sewage pipe assembly before you can remove it. This results in a large maintenance workload, difficulty in reinstallation, and the possibility of damage or scrapping of the protective plate at the pipe mouth.

[0003] In view of the above, a detachable guard plate structure for the pipe mouth of an evaporative cooler has been developed. Utility Model Content

Compared with the existing traditional structures and assembly methods, the utility model has significant practicality and economic benefits, is of great significance, and is suitable for popularization and use.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a detachable guard plate structure for the pipe mouth of an evaporative cooler, comprising an evaporative cooler, an outer guard plate at the pipe mouth corresponding to the pipe mouth of the evaporative cooler is set as a pipe mouth outer guard plate, a notch for a pipe pipe to pass through is arranged at the upper end of the pipe mouth outer guard plate, connecting holes are evenly distributed around the notch, rivet nuts are arranged in the connecting holes, a pipe mouth sealing plate is arranged at the outer side of the pipe mouth outer guard plate corresponding to the notch, a sealing gasket is arranged between the pipe mouth sealing plate and the pipe mouth outer guard plate, one end of the pipe pipe passes through the pipe mouth sealing plate and is connected to the pipe mouth of the evaporative cooler, a sealing flange is arranged on the periphery of the pipe pipe, and the pipe mouth sealing plate, the pipe mouth outer guard plate and the sealing flange are connected and sealed by screws.

[0006] Furthermore, the sealing gasket is a single-sided sealing gasket, which is divided into a non-adhesive surface and an adhesive surface, and the adhesive surface is adhered to the outer protective plate of the pipe opening.

[0007] Furthermore, the sealing flange is a component, which consists of an inner flange, a sealing gasket, and an outer flange. The inner flange is located on the inner side of the pipe mouth outer protective plate, and the outer flange is located on the outer side of the pipe mouth sealing plate.

[0008] The beneficial effects of the utility model are as follows: during regular inspection, overhaul and maintenance of the equipment and replacement of internal parts of the upper box components, there is no need to cut open the outer protective plate or cut off the medium pipe flange, and the sewage outlet connecting pipe assembly can be purged. The outer protective plate at the pipe mouth can be removed, and reinstallation is convenient, shortening the overhaul and maintenance time and reducing the overhaul and maintenance costs. Compared with the existing traditional structure and assembly method, it has significant practicality and economic benefits, is of great significance, and is suitable for popularization and use; the parts not described in detail in the utility model are existing commonly used technologies.

[0014] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0015] like Figure 1-Figure 4 As shown, the outer guard plate 1 of the pipe mouth is the outer guard plate with the pipe mouth in the upper box component, and the other guard plates are arranged around it. The contact part between the outer guard plate 1 of the pipe mouth and the other guard plates is paved with sealing strips, and is sealed by self-tapping connection; a notch and a connecting hole are opened on the outer guard plate 1 of the pipe mouth, and the sealing gasket 5 is pasted on the outer guard plate 1 of the pipe mouth. The pipe mouth sealing plate 2 contacts the non-adhesive surface of the sealing gasket 5, and the pipe mouth sealing plate 2 is fixed to the outer guard plate 1 of the pipe mouth by screws; the connecting pipe 3 passes through the reserved hole on the pipe mouth sealing plate 2 and the sealing flange 4 at the same time, and the sealing flange 4 and the pipe mouth sealing plate 2 are fixed from the outside to the inside by screws, and the sealing gasket is placed between the outer flange and the pipe mouth sealing plate 2 for sealing, and the blowing and draining components and flanges are welded to the outside of the connecting pipe 3, and a sealing gasket 5 is arranged between the pipe mouth sealing plate 2 and the outer guard plate 1 of the pipe mouth.

[0016] When disassembling the outer guard plate 1 of the pipe mouth: first remove the screws and self-tapping screws between the pipe mouth sealing plate 2 and the outer guard plate 1 of the pipe mouth, then remove the screws between the sealing flange 4 and the outer guard plate 1 of the pipe mouth, move the pipe mouth sealing plate 2 together with the sealing flange 4 outward along the connecting pipe 3, and then remove the self-tapping screws connecting the outer guard plate 1 of the pipe mouth and the other guard plates, and the outer guard plate 1 of the pipe mouth can be disassembled.
