Description

[0001] This application is a divisional application of an invention patent application with an application date of July 27, 2022, application number 202210887901.1, and invention name being a production process and device for an energy-saving solidifying matrix. Technical Field

[0002] The invention relates to the field of greening, and relates to an energy-saving solidifying matrix production process and device. Background Art

[0003] In recent years, in order to promote greening and protect the environment, greening has begun to be done on roofs, artificial slopes, road isolation belts, high-rise walls and other places. When greening, the more common method is: first place the culture soil in a plastic tray or non-woven bag, then put the plant seeds in the culture soil, and after the plants grow, transfer the plants together with the plastic tray or non-woven bag to the roof, artificial slope and other places. However, after such construction, due to the heavy weight of the substrate, the force on the base is very heavy, which is easy to cause safety hazards, and the water and soil are easy to lose, the drainage performance is poor, it is easy to harden in heavy rainy weather, and dusty in sunny weather, which is not conducive to plant growth and environmental protection.

[0004] In the prior art, some researchers have proposed the use of a solidifying matrix (whose raw materials include base soil, plant fiber, nutritional components and binders, etc.). Since the preparation process requires steam heating, the moisture content of the solidifying matrix is ​​very high. Therefore, traditional solidifying matrices require drying treatment, which has high drying costs and long production cycles, and is not conducive to large-scale production. Since the solidifying matrix is ​​not hard enough, it is easy to collapse and deform during stacking, which reduces space utilization and is not conducive to mechanized processing. In the demolding process of the solidifying matrix, a flip mold demolding method or an ejection demolding method is often used. Flipping the mold requires flipping the mold, the mold weight is small, and the precision is low. Ejection demolding requires the design of an ejection mechanism, the mold structure is complex, and the reliability is poor.

[0005] Since the preparation process requires steam heating, the thickness of the solidification matrix cannot be too thick. In the existing process, the fiber soil cannot be solidified to exceed the limit of 5 cm. The thickness of a single piece of solidification matrix limits its application range, which is not conducive to the large-scale promotion and application of the solidification matrix.

[0006] Based on this, it is necessary to develop an energy-saving solidification matrix production process and device to fundamentally solve the above problems. Summary of the invention

[0007] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an energy-saving solidification matrix production process and device. The production process of the solidification matrix does not require drying treatment. The solidification matrix has the characteristics of light weight, excellent drainage performance, simple construction, conducive to plant growth, and green environmental protection, which has become an urgent need in the three-dimensional greening industry.

[0008] In order to achieve the above object, the present invention provides the following technical solutions:

[0009] The present invention provides an energy-saving solidifying matrix, which comprises fiber culture soil and a skeleton;

[0010] The skeleton comprises a frame body and a plurality of support columns arranged on the frame body, wherein the frame body is a mesh structure and is arranged at the bottom of the solidified matrix; the support columns penetrate the thickness of the fiber culture soil layer;

[0011] The bottom of the frame body is provided with a plurality of protrusions, which are adapted to the positions of the support columns, so that the upper and lower layers of the solidified matrix can be seamlessly attached to each other during forward stacking, and a convection gap can be formed between the upper and lower layers of the solidified matrix during reverse stacking;

[0012] A filter layer is provided between the frame body and the fiber culture soil layer. The filter layer can prevent fiber soil residue from falling off and clogging the drainage hole and the drainage pipe.

[0013] The diameter of the protrusion is smaller than the inner diameter of the support column, and the support column is a hollow structure. During forward stacking, the protrusion of the upper solidified matrix is ​​just embedded in the support column of the lower solidified matrix, so that the upper and lower layers of the solidified matrix are seamlessly fitted together; during reverse stacking, the protrusions of the upper and lower layers of the solidified matrix contact each other, forming a convection gap between the upper and lower layers of the solidified matrix, which is conducive to air convection.

[0014] The filter layer is made of non-woven geotextile.

[0015] The frame is made by injection molding, and the material of the frame is one or more of metal, resin and plastic.

[0016] There are four support columns, and the upper surface of the solidified matrix is ​​provided with a barb structure, and the barb structure is fixedly connected to the top of the four support columns. By providing the barb structure, the skeleton can be quickly lifted to take the solidified matrix product out of the mold.

[0017] A connection structure is provided between adjacent units of the framework to increase stability during splicing.

[0018] The side of the frame body is provided with a buckle joint, and the adjacent frame body is provided with a groove adapted thereto, forming a buckle connection structure, which is convenient for assembling multiple solidifying matrices together to realize the overall installation of the roof.

[0019] The raw materials of the fiber culture soil include base soil, plant fiber, nutrient components and a binder; the fiber culture soil of the present invention is made by using existing technology or obtained through commercial channels, and the fiber culture soil is adjusted according to the characteristics of the cultivated plants.

[0020] The present invention also provides a production process of the energy-saving solidification matrix, comprising the following steps:

[0021] (1) preparing a skeleton by injection molding;

[0022] (2) mixing the raw materials of the fiber culture soil uniformly to obtain the fiber culture soil;

[0023] (3) Place the frame at the bottom of the mold, keep the support column facing upward, lay the filter layer on the upper surface of the frame body, add the fiber culture soil, scrape it flat after filling, and perform mold closing and hot pressing in sequence to solidify the fiber culture soil, filter layer, and frame;

[0024] The bottom of the mold body is provided with a plurality of grooves, and the grooves are matched with the raised parts at the bottom of the frame body;

[0025] (4) Finally, demoulding is performed to obtain the solidified matrix.

[0026] The pressing block of the mold is provided with a high-temperature steam heating system.

[0027] A plurality of water outlet holes are evenly distributed on the mold bottom plate.

[0028] An energy-saving solid matrix production device, the mold includes a mold body and a pressing block, the top of the mold body is open; the pressing block is located directly above the mold body, the pressing block is connected to a pressure mechanism, and under the action of the pressure mechanism, the pressing block moves up and down along the inner wall of the mold body;

[0029] The bottom of the mold body is provided with a plurality of grooves, and the grooves are adapted to the raised portions at the bottom of the frame body;

[0030] A plurality of water outlet holes are evenly distributed on the bottom plate of the mold body;

[0031] The pressing block is provided with a high-temperature steam heating system, and a plurality of steam holes are evenly distributed on the pressing block panel.

[0032] Compared with the prior art, the beneficial technical effects of the present invention are:

[0033] (1) The energy-saving solidifying matrix provided by the present invention can achieve seamless bonding of the upper and lower layers of solidifying matrix during forward stacking by providing a protrusion, a support column and a connection structure, so as to obtain an ultra-thick solidifying matrix, thereby solving the problem that the traditional fiber soil layer cannot break through the 5 cm limit. The solidifying matrix can be spliced ​​into a flower box or a magic cube, thus achieving overall matrix solidification. The ultra-thick solidifying matrix can enhance the cold resistance of plants in the extremely cold northern regions and broaden the scope of application.

[0034] (2) The energy-saving solidifying matrix provided by the present invention forms a convection gap between the upper and lower layers of solidifying matrices when stacked in reverse, which helps the water in the fiber soil to evaporate and dry without the need for drying treatment; by providing a raised portion, it is equivalent to providing a water storage and drainage board on the bottom surface of the solidifying matrix during paving, which is conducive to the solidifying matrix to discharge accumulated water and prevent the solidifying matrix from accumulating too much water and causing overload of the roof.

[0035] (3) The energy-saving solidifying matrix provided by the present invention combines the fiber culture soil and the skeleton by bonding and winding. The stacking weight is borne by the supporting columns of the skeleton, so that the fiber culture soil will not be crushed. It is not easy to collapse and deform during stacking, which is conducive to mechanized operation.

[0036] (4) The energy-saving solidifying matrix provided by the present invention combines the functions of "fiber soil layer + filter layer + drainage and storage board", realizing the "three-in-one" function, and the paving operation effect is higher and more convenient.

[0037] (5) The present invention provides a production process for an energy-saving solidifying matrix. The skeleton structure is embedded in the solidifying matrix, and the moisture content in the fiber soil is reduced by natural drying. The fiber soil can then be directly picked up and stacked, which greatly reduces transportation costs. It not only saves drying energy consumption and oven costs, but also breaks through the production capacity bottleneck of drying, which has great economic significance.

[0038] (6) The present invention provides an energy-saving solid matrix production device. Since a mold removal structure is provided on the frame, the frame can be quickly lifted to remove the solid matrix product from the mold, and the mold removal is more labor-saving and efficient. Compared with the flip mold removal method, there is no need to flip the mold, the mold weight can be larger, the mold structure design is less restricted, the accuracy can be improved, and the mold reliability is improved. Compared with the ejection mold removal method, there is no need to design an ejection mechanism, the mold structure is simplified, and the reliability is higher. BRIEF DESCRIPTION OF THE DRAWINGS
