Description

TECHNICAL FIELD

[0001] The application relates to the technical field of cold storage heat preservation walls, in particular to a cold storage heat preservation wall. BACKGROUND

[0002] With the rapid development of the cold chain logistics industry, the demand for cold storage is increasing, and the cold storage heat preservation wall can maintain the stability of the internal temperature of the cold storage and effectively block the invasion of external heat. It mainly reduces the temperature exchange between the inside and outside of the cold storage through high-performance heat preservation materials and precise structural design, thereby ensuring that the inside of the cold storage continuously maintains the required low-temperature environment.

[0003] The existing patent (publication number: CN204983233U) discloses a cold storage heat preservation wall plate, which comprises a moisture-proof paint layer arranged in the wall body, an inorganic resin fireproof plate arranged on the inner side of the wall body, hard polyurethane foam sprayed between the inorganic resin fireproof plate and the wall body, and a finishing layer arranged on the outer surface of the wall body. The hard polyurethane foam of the cold storage heat preservation wall plate will not splash and affect the loss of the material.

[0004] Traditional cold storage usually uses a single thickness of polyurethane foam or other simple sandwich structure as a heat preservation material. Although this structure can achieve basic heat insulation function, it has obvious limitations in heat preservation performance, moisture resistance, aging resistance and long-term energy efficiency under extreme climate conditions, and cannot meet the heat preservation demand under extreme harsh environments. CONTENT OF THE UTILITY MODEL

[0005] In view of the shortcomings of the prior art, the application provides a cold storage heat preservation wall, which has the advantages of significantly improving heat preservation efficiency and stability, enhancing moisture and mildew resistance, prolonging service life, optimizing energy efficiency, and meeting the heat preservation demand of the wall under extreme harsh environments. The problems of traditional heat preservation materials, such as decreased heat preservation performance under extreme climate conditions, insufficient moisture resistance, easy aging and poor long-term energy efficiency, are solved.

[0006] To achieve the above purpose, the application provides the following technical scheme: a cold storage heat preservation wall, comprising a wall body, an outer protective layer arranged on the front surface of the wall body, the outer protective layer comprising a plurality of galvanized plates arranged at equal intervals, a closed cavity formed between the wall body and the outer protective layer, the closed cavity being filled with a heat preservation core material, the heat preservation core material being modified polyisocyanate rigid foam, each galvanized plate being fixedly connected with a surrounding plate on the front surface, each surrounding plate being provided with a plurality of butt joints arranged at equal intervals in the interior, each butt joint being provided with a double-headed bolt, and the outer circumferential surface of each double-headed bolt being threadedly connected with a first nut, and the interior of the wall body being provided with a plurality of expansion bolts arranged at equal intervals.

[0007] Through the above scheme, since the traditional thermal insulation material has poor thermal insulation performance under extreme climate conditions, insufficient moisture resistance, easy aging and poor energy efficiency for a long time, by setting an outer protective layer composed of galvanized sheets and filling a modified polyisocyanurate rigid foam material thermal insulation core material between the wall and the protective layer, the thermal insulation efficiency and stability of the thermal insulation wall can be significantly improved, the moisture and mildew resistance is enhanced, the service life is prolonged, and the energy efficiency performance is optimized, meeting the thermal insulation needs of the wall under extreme harsh environments.

[0008] Further, the inside of each galvanized sheet is provided with a mounting hole, and the galvanized sheet is slidably connected with the expansion bolt through the mounting hole.

[0009] Through the above scheme, the second nut on the back of the galvanized sheet can play a limiting role, avoiding the extrusion of the galvanized sheet to the thermal insulation core material, which can cause damage to the thermal insulation core material. The second nut on the front of the galvanized sheet plays a positioning role, which can fix the galvanized sheet and facilitate the installation and removal of the galvanized sheet.

[0010] Further, the outer periphery of each expansion bolt is slidably connected with two spacers, and the spacers are located between the second nut and the galvanized sheet.

[0011] Through the above scheme, the setting of the spacer not only effectively disperses the pressure generated when the nut is tightened, preventing the galvanized sheet from deforming due to excessive extrusion, but also improves the stability of the positioning of the galvanized sheet.

[0012] Further, the inside of the thermal insulation core material is provided with a recess, and the second nut and the spacer on the back of the galvanized sheet are located inside the recess.

[0013] Through the above scheme, the second nut and the spacer are avoided from being installed in conflict with the thermal insulation core material, facilitating the installation of the second nut and the spacer.

[0014] Further, the inside of each thermal insulation core material is provided with four limiting holes, and the thermal insulation core material is slidably connected with the expansion bolt through the limiting hole.

[0015] Through the above scheme, the thermal insulation core material is limited to avoid easy deviation, improving the stability of the thermal insulation core material as a whole, and further improving the stability of the thermal insulation wall as a whole.

[0016] Further, the inside of each thermal insulation core material is provided with equidistantly arranged holes.

[0017] Through the above scheme, the setting of the hole facilitates gas exchange, prompting the thermal insulation core material to discharge excess moisture and preventing dewing phenomenon.

[0018] Further, the top end and the bottom of the front of each of the galvanized plates are provided with a first sealing strip, the second sealing strip is arranged between the adjacent surrounding plates, and the left end and the right end of the front of the galvanized plate located at the leftmost end and the rightmost end are respectively provided with a third sealing strip.

[0019] Through the above scheme, the first sealing strip, the second sealing strip and the third sealing strip can seal the edges of the galvanized plate, effectively prevent the invasion of external air, water vapor and dust, and guarantee the heat preservation effect of the heat preservation wall.

[0020] Further, the front of the wall body is coated with moisture-proof paint.

[0021] Through the above scheme, the moisture-proof paint can not only effectively block the invasion of external moisture, but also enhance the corrosion resistance and durability of the wall body.

[0022] Compared with the prior art, the technical scheme of the present application has the following beneficial effects:

[0023] The cold storage heat preservation wall body, by setting the outer protective layer composed of galvanized plates, and filling the modified polyisocyanurate hard foam material heat preservation core material between the wall body and the protective layer, can significantly improve the heat preservation efficiency and stability of the heat preservation wall body, enhance its moisture-proof and mildew-proof performance, prolong its service life, and optimize its energy efficiency performance, meet the heat preservation needs of the wall body in extremely harsh environments, set the surrounding plates and the butt joint grooves, and use the double-end bolts and the first nuts to connect and reinforce the adjacent surrounding plates, which can improve the stability of the outer protective layer as a whole, and further improve the stability of the heat preservation wall as a whole, and set the sealing strips on the edges of the galvanized plates, which can seal the gaps of the edges of the galvanized plates, guarantee the sealing effect of the heat preservation wall, and further guarantee the heat preservation effect of the heat preservation wall.
