[0041] There are many types of glass kilns. With the continuous progress of science and technology, the signs of progress in glass kilns in recent years are: high efficiency, low consumption, long furnace life and large-scale. Especially in the photovoltaic glass industry, kilns tend to develop in large-scale, such as the construction of glass kilns with a capacity of more than 1000t / d, five lines, six lines, and eight lines.

[0042] This super-large kiln occupies a large area and has a large span of the factory building. Due to the characteristics of the kiln combustion mode (air reversing combustion-supporting mode), it is necessary to build a heat storage chamber 210 to achieve heat storage and conduction heat transfer, so as to achieve heat recovery and utilization, and achieve the purpose of energy saving and consumption reduction. The height space of the heat storage chamber 210 is relatively large. The existing kiln arranges the heat storage chamber 210 and the flue 220 in the pit, so the pit in the kiln area is large and deep. The kiln built by this method of building a glass kiln has the following disadvantages: first, it may cause the pit to be flooded when it rains, resulting in uneven settlement of the foundation; second, the space at the bottom of the kiln is small and the air circulation is poor, which makes it more difficult to install and maintain a series of equipment in a hot and humid environment; third, in order to prevent water and settlement, it is necessary to build shear walls around the pit and waterproof the shear walls; and lay raft slabs in the pit to prevent settlement. The existing glass kiln masonry method has high masonry difficulty, low masonry efficiency, and a long masonry cycle.

[0043] Based on the above analysis, the present invention proposes a glass kiln masonry method, which does not require digging a pit, greatly reduces the masonry cost and shortens the masonry period, and the kiln built by the method will not have problems such as pit flooding when it rains and uneven foundation settlement caused by groundwater; and the equipment is relatively convenient to maintain.

[0044] The following is the attached Figure 1 To Attachment Figure 3 , describing the glass furnace masonry method of the first embodiment of the present invention.

[0045] Reference Figure 1 The glass furnace masonry method of this embodiment comprises the following steps:

[0046] Select or build a stepped terrain structure, wherein the stepped terrain structure includes a first plane 110 and a second plane 120 distributed in a height direction;

[0047] Building a heat storage structure on the first plane 110;

[0048] A second-layer structure 300 is built above the first plane 110 and flush with the second plane 120;

[0049] A melting furnace 400 is built on the two-story structure 300 , and a production building 500 is built on the second plane 120 and / or the two-story structure 300 , wherein the production building 500 is located at one side of the melting furnace 400 .

[0050] Compared with the traditional glass kiln building method in which the heat storage chamber 210 and the flue 220 are set in the pit, the glass kiln building method in the embodiment of the present invention directly builds the kiln on the stepped terrain, and builds the heat storage structure on the first plane 110 located below, thereby increasing the space on the outer peripheral side of the heat storage structure, facilitating the installation, daily maintenance and other operations of the internal equipment of the heat storage structure and the auxiliary equipment of the glass kiln; promoting the circulation of air on the outer peripheral side of the heat storage structure, and improving the environment at the bottom of the kiln; and, it can also avoid problems such as water filling the pit during rain and uneven foundation settlement caused by groundwater during the use of the glass kiln; at the same time, it can also reduce the difficulty of building the glass kiln, improve the building efficiency of the glass kiln, and shorten the building period of the glass kiln.

[0051] It is understandable that the production plant 500 can be built on the second plane 120, which can reduce the load-bearing capacity of the second-layer structure 300, thereby making the structure of the glass furnace built by the glass furnace building method of the embodiment of the present invention more stable and having a longer service life; and can also reduce the building cost of the second-layer structure 300. At this time, the steel structure of the production plant 500 is located on one side of the melting furnace 400. Of course, if Figure 3As shown, a production building 500 may also be built on both the second plane 120 and the second-floor structure 300 , and the steel structure of the production building 500 is located on the outer peripheral side of the melting furnace 400 .

[0052] It can be understood that building the second-layer structure 300 flush with the second plane 120 above the first plane 110 includes the following steps:

[0053] Building support columns 310 on the first plane 110;

[0054] A floor slab 320 is built on the supporting columns 310 .

[0055] Specifically, the melting furnace 400 is built on the floor 320. By doing so, the ventilation effect below the melting furnace 400 is enhanced, thereby reducing the temperature below the melting furnace 400, thereby avoiding a hot and stuffy environment below the melting furnace 400, so as to facilitate operators to install and maintain equipment below the melting furnace 400. It can be understood that the floor 320 is flush with the second plane 120.

[0056] It is understandable that the glass furnace masonry method of some embodiments of the first aspect of the present invention further includes the following steps:

[0057] A cooling fan for cooling the melting furnace 400 is disposed on the first plane 110 and is spaced apart from the regenerator structure.

[0058] By such an arrangement, the furnace cooling air system is separated from the melting furnace 400 and the heat storage chamber 210, which reduces the heat dissipation of the melting furnace 400 and lowers the ambient temperature below the melting furnace 400, thereby reducing the operating energy consumption of the furnace cooling fan.

[0059] It can be understood that building the thermal storage structure on the first plane 110 includes the following steps:

[0060] Two heat storage chambers 210 are built on the first plane 110 and are spaced apart from each other;

[0061] A flue 220 communicating with the two heat storage chambers 210 is built between the two heat storage chambers 210 .

[0062] Combination Figure 3 Specifically, the flue 220 includes a main flue 221 and a branch flue 222 , and two ends of the branch flue 222 are connected to the main flue 221 and the heat storage chamber 210 respectively.

[0063] It can be understood that building the heat storage structure on the first plane 110 also includes the following steps:

[0064] A heat-insulating wall 230 is built on the outer periphery of the heat storage chamber 210 and the flue 220 .

[0065] The heat preservation effect of the heat storage structure can be enhanced by building the heat preservation wall 230. Specifically, the heat preservation wall 230 is connected to the floor 320.

[0066] It is understandable that before building the thermal storage structure on the first plane 110, the following steps are also included:

[0067] A pile foundation is driven on the first plane 110 .

[0068] By driving the pile foundation, the structure of the glass furnace built by the glass furnace building method of the first embodiment of the present invention can be made more stable. It can be understood that the structure of the pile foundation, the position of the pile foundation and the method of driving the pile foundation are all prior art and will not be described in detail here.

[0069] It can be understood that the height difference between the first plane 110 and the second plane 120 is 5-6 m.

[0070] Combination Figure 1 Specifically, the stepped terrain structure used in the glass furnace masonry method of the first embodiment of the present invention includes two planes distributed in the height direction, namely a first plane 110 and a second plane 120. Figure 2 Specifically, the stepped terrain structure used in the glass furnace masonry method of the first embodiment of the present invention includes at least three planes distributed in the height direction, wherein the plane located at the bottom is the first plane 110, the plane located at the top is the second plane 120, and the other planes are located between the first plane 110 and the second plane 120. Taking the stepped terrain structure including three planes distributed in the height direction as an example, the three planes from bottom to top are the first plane 110, the third plane 130 and the second plane 120. When the support column 310 is built, the support column 310 is built on both the first plane 110 and the third plane 130.

[0071] Combine the following Figures 1 to 3 , describing the glass kiln of the second embodiment of the present invention, which is built by the above-mentioned glass kiln building method. The space on the outer peripheral side of the heat storage structure of the glass kiln built by the above-mentioned glass kiln building method of the first embodiment is larger, which is convenient for the installation and daily maintenance of the internal equipment of the heat storage structure and the auxiliary equipment of the glass kiln, and makes the air on the outer peripheral side of the heat storage structure more circulated; and it can also avoid problems such as uneven foundation settlement caused by water filling the pit during rain and groundwater during the use of the glass kiln.

[0072] It can be understood that the glass furnace of some embodiments of the first aspect of the present invention includes a heat storage structure, a melting furnace 400 and a production plant 500, and the heat storage structure is arranged below the melting furnace 400 and the production plant 500.

[0073] It is understandable that the glass furnace of some embodiments of the first aspect of the present invention further includes a cooling fan, which is arranged on one side of the heat storage structure and is used to cool the melting furnace 400.

[0074] It should be noted that the masonry method of the heat storage structure, the masonry method of the two-layer structure 300, the masonry method of the melting furnace 400 and the masonry method of the production plant 500 involved in the embodiments of the present invention are all conventional technical means and will not be elaborated here.
