Description

Technical Field

[0001] The invention relates to a porous ceramic material produced with industrial waste residue as raw material, in particular to a metal reinforced connection porous ceramic filler module used for a heat exchange filler core of an evaporative cooling air conditioning device. Background Art

[0002] Evaporative cooling air conditioners are air conditioning equipment based on the principle of water evaporation cooling heat exchange. When air flows between water films, the enthalpy and humidity difference between the air on the water film surface and the flowing air causes water to diffuse from the water film surface into the air, i.e., evaporation occurs. In this process, water vapor absorbs a large amount of latent heat, causing the temperature of the air and water to drop. The filler in the evaporative cooling air conditioner is the place where water vapor exchanges heat.

[0003] Evaporative cooling air conditioning filler, also known as wet curtain, is the core component of evaporative cooling air conditioning, and its performance has a decisive influence on the operation effect of the air conditioner. The physical properties of the filler, including thickness, specific surface area, material, etc., are highly correlated with the evaporative cooling efficiency and other application performance of the unit. The ideal filler should have the following characteristics: large specific surface area and strong water absorption capacity; corrosion resistance, not easy to breed bacteria; good wet stiffness, not easy to collapse and deform in long-term contact with water; good flame retardancy, reducing the risk of fire caused by electrical faults; and environmentally friendly, non-toxic and harmless. Commonly used filler types include paper curtains and PVC (polyvinyl chloride) curtains. Paper curtains are favored for their large specific surface area, strong water absorption capacity, easy production, and low cost, but they have short service life, insufficient antibacterial and mildew resistance, and poor flame retardancy, which poses health and safety risks. Although PVC curtains are easy to produce, low cost, flame retardant and mildew-proof, they have poor water absorption and cooling efficiency.

[0004] In order to overcome the defects of paper curtains and PVC curtains, the researchers used porous ceramics as an alternative material and further processed them into porous ceramic fillers. The porous ceramic surface has densely distributed macroporous structures and has the characteristics of strong water absorption. At the same time, due to its inorganic nature, it also has the characteristics of flame retardancy, mildew resistance, and long life. Porous ceramic fillers combine the advantages of paper curtains and PVC curtains and are the best choice for heat exchange fillers in evaporative cooling air conditioning units.

[0005] The researchers continue to explore the industrialization path of porous ceramic fillers, assembling scattered porous ceramic sheets into modules through a fixed frame, and have applied for a number of patents, such as "A through-type porous ceramic wet curtain" (CN104197445B) and "A stacked porous ceramic wet curtain" (CN204084701U). In 2019, the researchers further simplified the design of the fixed frame, adopted a belt-type fixing frame, and applied for a patent for "A belt-type porous ceramic filler" (CN201921413554.9), which greatly simplified the production process of the product. In 2021, the researchers further optimized the process, improved the porous ceramic filler into an integral structure that does not rely on an external frame, and applied for a patent for "An integral porous ceramic filler" (ZL202110737499.4). In 2023, the researchers continued to improve the process and applied for a patent for "A self-connected porous ceramic filler" (ZL202320084070.4).

[0006] During the research and development process, the developers continuously improved the product's performance, seeking a balance between the best performance and production convenience, in order to achieve the industrialization of the patented product. In response to the problems that occurred during use, the developers further optimized the product structure and applied for a patent for "metal-reinforced connection of porous ceramic filler modules". This patent connects and fixes porous ceramic sheets through metal strips to form a stable overall structural module, thereby significantly improving the strength performance of the product. Summary of the invention

[0007] The purpose of the present invention is to provide a metal-reinforced porous ceramic filler module. This is essentially different from previous patents of the same series in which ceramic sheets rely on a fixed frame, or are connected by connecting components, or are not completely cut and connected by retaining the original partial structure. The present invention embeds metal strips into multiple ceramic sheets, so that the multiple ceramic sheets are restored to the module shape before cutting, and have regularly arranged ventilation and water channels, thereby improving the strength of the filler and avoiding damage to the product during transportation and use.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0011] A metal strip corresponding to the groove opening passes through the groove openings of a plurality of regularly arranged porous ceramic sheets and is sealed by an adhesive.

[0012] The metal-reinforced porous ceramic filler module as described above further comprises a protective outer sheet, which is arranged on the outer side of a structure formed by a plurality of porous ceramic sheets regularly arranged in one direction.

[0013] The metal reinforced connection porous ceramic filler module as described above further comprises corner protection strips, which are arranged at four corners of a structure formed by a plurality of porous ceramic sheets regularly arranged in one direction.

[0014] The metal reinforced connection porous ceramic filler module as described above, further, each of the porous ceramic sheets is provided with grooves at multiple positions.

[0015] The metal reinforced connection porous ceramic filler module as described above, further, the plurality of porous ceramic sheets are perpendicular to the horizontal plane and two adjacent porous ceramic sheets are parallel to each other.

[0016] The metal reinforced connection porous ceramic filler module as described above, further, the plurality of porous ceramic sheets are inclined to a horizontal plane and two adjacent porous ceramic sheets are parallel to each other.

[0018] The metal reinforced connection porous ceramic filler module as described above, further, the adhesive is slot filling putty.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention innovatively uses metal strips to support and connect multiple ceramic sheets from the inside, making full use of the high strength and toughness of the metal to reinforce the ceramic sheets, thereby greatly improving the structural strength of the filler.

[0021] 2. The metal strips of the present invention are respectively embedded in the four corners of the square ceramic sheet and sealed with inorganic structural adhesive, which enables the filler to form a stable and strong square module structure, thereby significantly improving the seismic strength of the ceramic.

[0022] 3. In order to further enhance the stability of the module structure, the module of the present invention is specially equipped with corner guards and protective outer sheets on the four sides and two sides. This not only further protects the module structure, but also significantly improves its anti-seismic strength, effectively avoiding the damage of the ceramic sheet caused by vibration during transportation and use.

[0023] 4. The packing modules of the present invention are neat, stable and firm, which enables them to be conveniently assembled and stacked during transportation and operation, and are not prone to shaking or collapse. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Furthermore, each of the porous ceramic sheets 1 is provided with groove openings 2 at multiple positions.

[0042] Furthermore, the plurality of porous ceramic sheets 1 are perpendicular to a horizontal plane and two adjacent porous ceramic sheets 1 are parallel to each other.

[0043] Furthermore, the plurality of porous ceramic sheets 1 are inclined to a horizontal plane and two adjacent porous ceramic sheets 1 are parallel to each other.

[0044] Furthermore, the depth and width of the groove opening 2 are greater than the diameter of the metal strip 3 .

[0045] Furthermore, the adhesive is slot-filling putty 4.

[0046] Embodiment 1:

[0047] Figure 1 It is a schematic diagram of the structure of a brick blank when multiple porous ceramic sheets are arranged vertically to a horizontal plane in an embodiment of the present invention; Figure 2 FIG. 1 is a schematic diagram of the overall structure of multiple porous ceramic sheets in an embodiment of the present invention when they are arranged vertically to a horizontal plane. Figure 1 and Figure 2 As shown, the metal reinforced porous ceramic packing module is composed of vertically arranged porous ceramic sheets 1, which are fixed on the inner side of the corner bead 5. The metal strip 3 is embedded in the groove 2 on the porous ceramic sheet 1, and the groove is sealed with a slot filling glue 4. After the slot filling glue 4 is cured, the porous ceramic sheets 1 are combined into a square porous ceramic packing module with regular channels 7, and protective outer sheets 6 are also installed on the left and right sides.

[0048] Embodiment 2:

[0049] Figure 3 It is a schematic diagram of the structure of a brick blank when a plurality of porous ceramic sheets are arranged obliquely to a horizontal plane in an embodiment of the present invention; Figure 4 FIG. 1 is a schematic diagram of the overall structure of multiple porous ceramic sheets in an embodiment of the present invention when they are arranged obliquely to a horizontal plane. Figure 3 and Figure 4As shown, the metal reinforced porous ceramic packing module is composed of porous ceramic sheets 1 arranged obliquely, which are embedded in the inner side of the corner bead 5. The metal strip 3 is embedded in the groove 2 on the porous ceramic sheet 1, and the groove is sealed with a slot filling glue 4. After the slot filling glue 4 is cured, the porous ceramic sheets 1 are combined into a square porous ceramic packing module with regular channels 7, and protective outer sheets 6 are added on the left and right sides.

[0050] Comparative Example 1:

[0051] like Figure 5 As shown, Comparative Example 1 shows a patent application with the patent name "A monolithic porous ceramic filler (ZL202110737499.4)". The patented technical solution is composed of a plurality of I-shaped porous ceramic plates, which are interconnected by supporting fixtures to form ventilation ducts, thereby facilitating heat exchange between air, water and steam on the porous ceramic surface. Two porous ceramic plates are respectively connected at both ends of the supporting fixture, so that the plurality of porous ceramic plates form a regularly arranged, monolithic three-dimensional structure with spaced channels.

[0052] Comparative Example 2:

[0053] like Figure 6 As shown, Comparative Example 2 shows a patent application with the patent name "A self-connected porous ceramic filler (ZL202320084070.4)". The patented technical solution connects the ceramic side plate and the ceramic sheet through a self-connector, and the self-connector has a through hole to facilitate water to pass from top to bottom. Channels are formed between the side plate and the ceramic sheet, and the ceramic sheet is spaced apart to facilitate heat exchange between air and water vapor. In this example, the self-connector is located at the central axis of the filler, and the ceramic sheets are arranged symmetrically up and down.

[0054] From the comparison, we can see the advantages of the present invention:

[0055] 1. With Figure 5 Compared with the comparative example 1 of "an integral porous ceramic filler (ZL201221469769.X)" shown in the figure, each ceramic sheet in the original invention requires several supporting fixing parts 2, and the ceramic sheets are connected two by two to form an integral plate through adhesive. The preparation process is relatively complicated, and the contact surface between the two is small. Vibration during transportation or use may easily cause falling off and breakage, and the structural stability is poor.

[0056] Each module of the present invention is connected and reinforced by a plurality of metal strips, and the adhesive is buried over a large area, so that the metal strips are tightly combined with the ceramic sheets, which greatly improves the strength of the module and enhances the ability to resist damage caused by vibration.

[0057] 2. Figure 6Although the "self-connected porous ceramic filler (ZL 202320084070.4)" of Comparative Example 2 solves the cumbersome preparation process of connecting two by supporting fixings in Comparative Example 1 and is more conducive to industrial production, it is found through practical application that the invention has two defects: (1) the self-connected body 1 blocks the channel 5, resulting in obstruction of water pouring from top to bottom and water splashing; (2) the four corners of the regularly arranged ceramic sheets 3 lack support, which can easily lead to breakage due to vibration during transportation or use.

[0058] The present invention adopts a metal strip connection method to replace the self-connected design, which effectively prevents the blockage problem; by embedding multiple metal strips into the four corners of the ceramic sheet and using the triple protection mechanism of metal, adhesive and frame, the structural strength, stability and seismic resistance of the module are enhanced. This ensures that the ceramic sheet will not be damaged in a vibrating environment. In addition, the preparation process of the present invention is simple and convenient, which is convenient for large-scale production.
