Description

Technical Field

[0001] The invention relates to the technical field of cold storage assemblies, and in particular to an integrated thermal insulation layer assembly structure used in a large cold storage. Background Art

[0002] Cold storage is related equipment that creates a temperature lower than the outdoor environment based on the refrigeration cycle system. Its core component is the compressor structure to achieve heat absorption / release. Conventional cold storage is an integrated assembled structure, but for large cold storage, on-site installation is often used.

[0003] In addition to the original piping system and refrigeration system layout, attention should also be paid to the design of the insulation layer. It should be noted that the insulation layer needs to take into account two key parameters: structural strength and thermal insulation performance. Therefore, the reinforced concrete structure and metal layer can be used as the supporting structure of the overall insulation layer, and insulation is performed by filling thermal insulation materials (foam, plastic, etc.). For the temperature environment on both sides of the insulation layer, especially for large-scale cold storage with high power, one side is in a low temperature environment for a long time, and the other side is in a room temperature environment. When the material is in a low temperature environment and a high temperature difference environment for a long time, its material properties will undergo non-directional changes, such as brittle / hard materials, low material strength and toughness, flexibility, elongation, thermal expansion coefficient and specific heat, etc., which will affect the service life and safety of the equipment. However, it should also be noted that the conventional cold storage structure cannot technically "sense" the degree of damage caused by the ambient temperature.

[0004] This application proposes a solution to this problem. Summary of the invention

[0005] The purpose of the present invention is to provide an integrated insulation layer assembly structure for large cold storage. For the insulation layer in large cold storage, in essence: the two sides of the insulation layer are respectively in a low temperature environment and a room temperature environment, which belongs to a high temperature difference environment. Especially in a low temperature environment, its material properties will undergo non-directional changes, which directly affects the service life and safety of the equipment.

[0007] A third packing layer is provided in the empty bag bin, and an inner circulation assembly is provided in the empty bag bin, the inner circulation assembly is composed of a water pump assembly, a water storage tank and a plurality of return water pipes, the water pump assembly and the water storage tank are arranged on the upper and lower sides of the empty bag bin from top to bottom, and the two ends of the return water pipe are respectively connected to the water storage tank and the water pump assembly.

[0008] It is further configured as follows: the leveling substrate layer is installed on a surface position on one side of the concrete base layer close to the lining base layer, the first filler layer is set close to the concrete base layer, the second filler layer is set close to the concrete base layer, and the empty bag bin is located in the middle position between the first filler layer and the second filler layer.

[0009] It is further configured that: the first filling layer and the second filling layer are both filled with a first-order thermal insulation medium, and the third filling bin is provided with a second-order thermal insulation medium.

[0010] It is further configured as follows: the outer diameter of the return pipe is equal to the distance between the first partition plate and the second partition plate, a positive flow position and a reverse flow position are arranged in the return pipe, and the return pipe is alternately arranged through the positive flow position and the reverse flow position, and the water pump assembly is composed of a water pump, a temperature sensor and a controller.

[0011] It is further configured as follows: the lower ends of the return pipe corresponding to the positive flow position and the reverse flow position are both installed in the water storage tank, the upper end of the return pipe corresponding to the positive flow position is installed at the water outlet end of the water pump, and the upper end of the return pipe corresponding to the reverse flow position is installed at the water inlet end of the water pump.

[0012] It is further configured as follows: a fixed cone is provided on the concrete base layer and penetrates the leveling substrate layer, the first partition plate and the second partition plate, one end of the fixed cone is drilled into the concrete base layer, and a stop pin plate corresponding to the first partition plate and the second partition plate is provided on the fixed cone.

[0013] It is further configured that: the distance between one end of the fixed cone and the stop pin plate close to the first partition plate is greater than the distance between the first partition plate and the concrete base, and the distance between the two stop pin plates is equal to the distance between the first partition plate and the second partition plate;

[0016] The present invention has the following beneficial effects:

[0017] 1. The overall structure is aimed at the construction method of large cold storage, specifically the insulation layer structure therein. Its essence is based on conventional concrete base and insulation medium, and the on-site environment or prefabricated concrete base is used as the reinforcement structure in the overall insulation structure to maintain the structural strength of the overall insulation structure. However, the difference is that a three-layer insulation structure is added based on the concrete base in a stacked installation method, corresponding to the first filler layer, the third filler layer and the second filler layer, wherein the first filler layer is used to maintain the temperature difference environment of the concrete base, and the second filler layer is used to insulate the inside of the cold storage to maintain the temperature difference environment. The focus is on the setting position of the third filler layer, which serves as a barrier structure between the first filler layer and the second filler layer to prevent the temperature difference environment in the second filler layer from further affecting the concrete base and preventing damage to the concrete base;

[0018] 2. In combination with the above content, it is supplemented that an inner circulation assembly is added to the empty envelope. The essence of the inner circulation assembly lies in the water circulation process. The key lies in that the return pipe therein not only serves as a water circulation channel, but also serves as a reinforcement structure between the first partition plate and the second partition plate. In addition, the flow direction of the water in the return pipe is further restricted, so that the water "passively absorbs or releases" heat in the empty envelope, and the temperature difference environment in the empty envelope further "blocks" the influence of the temperature difference on the concrete base.

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1: For the insulation layer in a conventional cold storage, its essence is based on insulation / thermal insulation materials. However, for a large cold storage, firstly, it is restricted by the installation method. Secondly, because the power of a large cold storage is large, the insulation layer therein is subjected to a greater degree of temperature difference. In a high temperature difference environment, the related structures in the insulation layer will cause non-directional changes in physical properties, such as becoming brittle and hard, etc. The following technical solutions are proposed for this:

[0030] Reference Figure 1 to Figure 7 The integrated insulation layer assembly structure for a large cold storage in this embodiment includes a concrete base layer 1 and an inner lining base layer 5, a leveling substrate layer 2, a first partition plate 9, and a second partition plate 10 are sequentially arranged between the concrete base layer 1 and the inner lining base layer 5, a first filler layer 7 is arranged between the leveling substrate layer 2 and the first partition plate 9, an empty bag bin 12 is arranged between the first partition plate 9 and the second partition plate 10, and a second filler layer 11 is arranged between the second partition plate 10 and the inner lining base layer 5;

[0031] A third packing layer 13 is provided in the empty bag bin 12, and an inner circulation assembly is provided in the empty bag bin 12, the inner circulation assembly is composed of a water pump assembly 4, a water storage tank 6 and a plurality of return water pipes 3, the water pump assembly 4 and the water storage tank 6 are arranged on the upper and lower sides of the empty bag bin 12 from top to bottom, and the two ends of the return water pipe 3 are respectively connected to the water storage tank 6 and the water pump assembly 4.

[0032] The leveling substrate layer 2 is installed on the surface of one side of the concrete base layer 1 close to the lining base layer 5, the first filling layer 7 is set close to the concrete base layer 1, the second filling layer 11 is set close to the concrete base layer 1, the empty bag bin 12 is located in the middle position between the first filling layer 7 and the second filling layer 11, the first filling layer 7 and the second filling layer 11 are both filled with first-order thermal insulation medium, and the third filling bin 13 is provided with a second-order thermal insulation medium.

[0033] Working principle: This invention mainly explains the insulation layer structure in large cold storage. Figure 1 , Figure 2 and Figure 4 For explanation, the overall insulation layer is based on the concrete base 1, and the concrete base 1 serves as a supporting structure in the overall insulation layer to maintain the structural strength of the overall insulation layer structure;

[0034] The first packing layer 7 and the second packing layer 11 are used as the heat preservation position in the overall structure. Figure 4 To explain, the first filler layer 7 is mainly for the concrete base 1, and its key function is to reduce the degree of heat generated by the external environment on the concrete base 1 transferred to the inside of the cold storage, and also to prevent the low temperature environment that may "leak" in the cold storage from affecting the concrete base 1. The second filler layer 11 is mainly used to isolate the temperature environment inside the cold storage. On this basis, the key is the empty envelope 12 set for the first filler layer 7 and the second filler layer 11. In theory, the empty envelope 12 serves as a "transit structure" in the temperature transfer process. Its essence is that when heat is transferred from the first filler layer 7 to the second filler layer 11, it will first pass through the third filler layer 13. Similarly, when heat is transferred from the second filler layer 11 to the first filler layer 7, it will also pass through the third filler layer 13. For this reason, the empty envelope 12 is filled with insulation material again to "mix" the heat transferred in the above two stages with the insulation material.

[0035] Embodiment 2: This embodiment is described as follows for the inner circulation assembly:

[0036] The outer diameter of the return pipe 3 is equal to the distance between the first partition plate 9 and the second partition plate 10. The return pipe 3 is provided with a positive flow position and a reverse flow position, and the return pipe 3 is alternately arranged through the positive flow position and the reverse flow position. The water pump assembly 4 is composed of a water pump, a temperature sensor and a controller. The lower ends of the return pipe 3 corresponding to the positive flow position and the reverse flow position are both installed in the water storage tank 6, the upper end of the return pipe 3 corresponding to the positive flow position is installed at the water outlet position in the water pump, and the upper end of the return pipe 3 corresponding to the reverse flow position is installed at the water inlet position in the water pump.

[0037] Solution description: In combination with the relevant contents in Example 1, it is explained again that the first packing layer 7 and the second packing layer 11 are filled with a first-order thermal insulation medium, and the third packing bin 13 is provided with a second-order thermal insulation medium, wherein the thermal insulation effect of the first-order thermal insulation medium needs to be greater than the thermal insulation effect of the second-order thermal insulation medium. The purpose is: in the initial stage, the first-order thermal insulation medium can better play the role of thermal insulation and avoid the temperature transfer process between the cold storage and the concrete base 1. However, in actual conditions, during the long-term operation of the cold storage, some heat will always "leak out". In this regard, according to Example 1 The relevant content of the invention is that the empty envelope 12 is used as a "transit structure" between the two temperature environments. However, in order to avoid the two temperature environments from influencing each other, it is necessary to ensure that the two temperature environments are "mixed" with each other in the empty envelope 12. The second-order thermal insulation medium can play a preliminary role in thermal insulation. However, the key is that the second-order thermal insulation medium has a certain air permeability. A brief description of the first-order thermal insulation medium and the second-order thermal insulation medium is as follows: the first-order thermal insulation medium includes polyurethane foam, polystyrene foam, rock wool, glass fiber, silicate foam, etc., and the second-order thermal insulation medium can be a material such as cotton.

[0038] But the key in this embodiment is the inner circulation structure, and its essence is: the water storage tank 6 is always full of water, combined with Figure 5 and Figure 3 To explain, during the operation of the cold storage, the temperature sensor in the water pump assembly 4 is used to detect the temperature sensor in the empty envelope 12. In theory, because the empty envelope 12 is between the first packing layer 7 and the second packing layer 11, the temperature environment inside it tends to room temperature. However, in actual operation, when the temperature inside the empty envelope 12 is significantly reduced, the water pump in the water pump assembly 4 is started to circulate the water in the water storage tank 6 along the return pipe 3. The purpose is to break the "equilibrium state" of the temperature difference environment in the empty envelope 12 by "passively absorbing or releasing" heat from the temperature environment inside the empty envelope 12 by the water body, thereby further changing the temperature environment inside the empty envelope 12. The key is to change the temperature difference environment on both sides of the first packing layer 7 and the second packing layer 11 to avoid changes in material properties caused by both being in a high temperature difference environment.

[0039] It should be noted that: by limiting the connection between the return pipe 3 and the pump, the circulation direction of the water body is changed to Figure 3 For example, the return pipe 3 is arranged in the vertical direction, but the water body does not circulate in a circular manner. Specifically, taking two adjacent return pipes 3 as an example, one end of one of the return pipes 3 is connected to the water inlet end of the water pump, and the water in the water storage tank 6 is pumped out from bottom to top, but the other return pipe 3 is connected to the water outlet end of the water pump, causing the water pumped out from the water storage tank 6 to flow back into the water storage tank 6 along the return pipe 3. The above method is used to illustrate: the amount of water in the water storage tank 6 will not change, but the water body is in a continuous flow state and changes the ambient temperature in the empty envelope 12.

[0040] Embodiment 3: This embodiment describes the construction process of the overall structure:

[0041] A fixing cone 14 is provided on the concrete base layer 1, which penetrates the leveling substrate layer 2, the first partition plate 9, and the second partition plate 10. One end of the fixing cone 14 is drilled into the concrete base layer 1, and a stopper plate 8 corresponding to the first partition plate 9 and the second partition plate 10 is provided on the fixing cone 14. The distance between one end of the fixing cone 14 and the stopper plate 8 close to the first partition plate 9 is greater than the distance between the first partition plate 9 and the concrete base layer 1, and the distance between the two stopper plates 8 is equal to the distance between the first partition plate 9 and the second partition plate 10.

[0042] The distance between the pin baffle plate 8 close to the second partition plate 10 and the other end of the fixed cone 14 is smaller than the distance between the second partition plate 10 and the lining base layer 5. The fixed cone 14 is provided with an air vent 15 at the internal position corresponding to the two pin baffle plates 8, and the internal position of the fixed cone 14 corresponding to the air vent 15 is hollow.

[0043] Solution Description: This embodiment is based on Figure 4 For example, firstly, the leveling substrate layer 2 is installed on the concrete base layer 1 for leveling, and the leveling substrate layer 2 and the first partition plate 9 are used as the "container structure" of the first filler layer 7, and similarly, the second partition plate 10 and the lining base layer 5 are used as the "container structure" of the second filler layer 11, among which the lining base layer 5 is the most relevant structure for solving the problem of the interior of the cold storage;

[0044] It should be noted that: during the construction process, firstly, a plurality of fixing cones 14 are inserted into the concrete base 1, wherein the stopper plate 8 is installed on the fixing cone 14 by means of threaded connection or the like. After the fixing cone 14 is installed, the leveling substrate layer 2 and the first partition plate 9 are installed in sequence, and sufficient space needs to be left between the two as the first filler layer 7. Then, the two stopper plates 8 are tightened in sequence on the fixing cone 14. The stopper plate 8 on the left side is used to reinforce the first partition plate 9, and the stopper plate 8 on the right side is used to support the second partition plate 10, and the inner circulation assembly is installed between the second partition plates 10.

[0045] It should be noted that: regarding the construction method of the first filler layer 7 and the second filler layer 11, they can be formed by filling or prefabricated installation. This part will not be explained in detail. What needs to be explained is: in order to further maintain the "transfer structure" in Example 2, the fixed cone 14 itself has the ability to transfer temperature. For this purpose, it is necessary to set the inner lining of the fixed cone 14 with respect to the empty cladding 12 to be hollow, so that the "temperature transfer" process carried out in the fixed cone 14 is finally gathered in the empty cladding 12, and the function of the air vent 15 is mainly to further mix the "temperature transfer" process carried out by the fixed cone 14 itself with the "temperature transfer" process in Example 2, and its ultimate goal is to avoid the "temperature transfer" process from influencing each other and aggravating the damage of related materials.

[0046] In summary: for the construction of large cold storage, the concrete base and the thermal insulation medium are used as the basis, and the concrete base is used as the reinforcement structure of the overall thermal insulation layer structure to meet the structural strength of the overall thermal insulation layer of the cold storage. However, there is a difference: three layers of thermal insulation structure are added through the stacking installation method. The first thermal insulation structure is for the concrete base, the third is for the inside of the cold storage, and the second is a barrier structure for the above two thermal insulation structures. Specifically, the empty bag bin is used as the main body, and the empty bag bin is combined with the inner circulation assembly to change the temperature difference between the first filling bin and the second filling layer. The function of the inner circulation assembly is to "passively absorb or release" heat through the active circulation of water, and maintain the temperature difference environment in the overall thermal insulation layer without affecting the temperature inside the cold storage, so as to avoid damage to the concrete base and other structures caused by the high temperature difference environment.
