[0030] See also Figures 1 to 3An embodiment of the present invention provides an insulation structure for a storage tank, including a tank body 1, an opening provided on the outer peripheral wall of the tank body 1, a plurality of ventilation windows 2 are provided on the opening at intervals, and a lifting component 3 is provided between adjacent ventilation windows 2, and the ventilation windows 2 are slidably provided with insulation plates 4, and the lifting component 3 is used to drive the insulation plates 4 to reciprocate along the height direction of the tank body 1.

[0031] The tank body 1 is a cylindrical shell structure made of a lightweight material, such as fiberglass. The tank body 1 is light, strong, corrosion-resistant, has good thermal properties, is easy to design, and is easy to install and construct. In a specific implementation, an opening is provided on the tank body 1. The opening is rectangular in shape, which facilitates the installation of a ventilation window 2 and a lifting assembly 3 at the opening. The insulation board 4 can be mounted on the ventilation window 2 via a slide rail or a cover, so that the insulation board 4 can seal the ventilation window 2 when closed. When the soy sauce in the storage tank requires air for fermentation, the insulation board 4 can be driven by the lifting assembly 3 to move to open the ventilation window 2, thereby allowing the tank body 1 to communicate with the outside world and allowing the outside air to enter the tank body 1 to achieve aerobic fermentation of the soy sauce. In cold weather, the lifting assembly 3 drives the insulation board 4 to close the ventilation window 2. The insulation board 4 has an insulation function and can reduce the heat loss rate of the tank body. In addition, the tank body 1 is made of fiberglass and has a low thermal conductivity. The tank body 1 and the insulation board 4 can maintain the fermentation temperature of the soy sauce in a reasonable range.

[0032] Specifically, when the technical solution of the present invention is applied, when the soy sauce needs to be replenished with air during the fermentation process, the operator controls the lifting assembly 3 to drive the insulation plate to open the ventilation window 2, so that the tank body 1 can be connected to the outside air, ensuring that the soy sauce can have enough oxygen for fermentation. When the tank body 1 needs to be insulated, the insulation plate 4 covers the ventilation window 2, that is, it plays the role of sealing the ventilation window 2. At the same time, the insulation plate 4 can also reduce the heat loss of the tank body 1. The insulation structure for the storage tank provided by the utility model realizes the opening and closing of the ventilation window through the insulation plate 4, can ventilate or insulate the tank body 1 according to the fermentation state of the soy sauce, ensure the fermentation quality of the soy sauce, and has the characteristics of simple structure and reasonable layout.

[0033] Furthermore, the ventilation window 2 of the thermal insulation structure for the storage tank includes a window frame 21 and a screen 22. The window frame 21 is connected to the tank body 1 by a glue seal, and the screen 22 is slidably arranged on the window frame 21. The window frame 21 is installed on the opening and can be fixed by a glue seal. In a specific embodiment, food-grade silicone is first placed on the side wall of the opening of the tank body 1 and on the end face of the window body, and then an epoxy sealing layer is filled between the two, so that the window frame 21 can be stably fixed to the opening, and the screen 22 is installed on the window frame 21.

[0034] Further, described screen window 22 comprises framework (not shown) and nylon filter (not shown), the material of described framework is made of stainless steel, and described nylon filter is composited by two layers of 40 order nylon nets and two layers of 20 order nylon nets, and the setting position of two layers of 40 order nylon nets is towards tank body 1, and 20 order nylon nets are arranged on the outside.Adopt four layers of nylon net to be arranged, and with two layers of 40 order compound two layers of 20 order nylon nets, can prevent the tiny organisms of the outside from entering in the storage tank, and can ensure that air can smoothly enter in the storage tank by the hole of nylon net.Nylon filter is arranged before framework, and nylon filter can first adopt boiling water disinfection, and framework can adopt the mode of immersion passivation treatment, improves the corrosion resistance of framework, avoids framework to be corroded by the salinity in soy sauce.

[0035] In another feasible method, in order to increase the flow of air in the storage tank, an interface for connecting to a vacuum pump can be provided in the storage tank. The position of the interface is arranged relative to the opening, thereby ensuring that the air entering the storage tank from the screen window 22 can be fully diffused and then discharged through the interface, thereby accelerating the flow rate of air in the storage tank and increasing the fermentation speed. In addition, in order to improve the quality of air entering the tank body 1, a fiber composite cotton cloth with a stronger filtering effect can be provided on the screen window 22. The fiber composite cotton cloth can filter microorganisms, PM2.5 particles, aerosols and other harmful substances in the air. Under the action of the vacuum pump, the air passes through the fiber composite cotton cloth and is forcibly sucked into the tank body 1, thereby ensuring the quality level of soy sauce during the air fermentation process.

[0036] like Figure 4 As shown, further, the above-mentioned lifting assembly 3 includes a rain cover 31 and a cylinder 32, the rain cover 31 is located between the ventilation windows 2 and connected to the ventilation windows 2, the cylinder 32 is arranged in the rain cover 31, and the output end of the cylinder 32 is connected to the insulation board 4.

[0037] The rain cover 31 can be made of plastic or metal material, and can be fixed to the ventilation window 2 by means of bolts 53. The cylinder 32 is arranged in the rain cover 31, and the output end of the cylinder 32 (i.e., the piston rod) is connected to the insulation board 4. After an air pressure is input into the cylinder 32 through the air compressor, the piston rod rotates along its own axis, driving the insulation board 4 to move up and down, thereby realizing the opening and closing of the ventilation window 2.

[0038] In another feasible manner, the lifting assembly 3 can also be driven by a motor. Specifically, under this setting, the insulation board 4 is connected to the ventilation window 2 through a slide rail, and a transmission rack is set on both sides of the insulation board 4. A stepper motor is set at the bottom of the rain cover 31, and the stepper motor is connected to the transmission gear, and the transmission gear and the transmission rack are meshed.

[0039] Furthermore, the above-mentioned insulation layer includes a shell (not shown), which is filled with the insulation layer. The shell covers the vent window 2 and can move relative to the vent window 2. The shell is connected to the lifting assembly 3.

[0040] Furthermore, the shell is made of stainless steel, and the insulation layer is a polyurethane foam layer.

[0041] Furthermore, the thickness of the polyurethane foam layer is 40 to 60 mm. The polyurethane resin is filled in the stainless steel shell, and under the action of the foaming agent, a polyurethane foam layer containing a large number of voids is formed. The thermal conductivity of the polyurethane foam layer is less than 0.033 W / m·k, which can reduce the heat exchange capacity between the outside and the tank body 1, reduce the rate of heat loss in low-temperature harsh environments, and slow down the rate of temperature rise in the tank under high-temperature environments, ensuring that the tank can ferment within a suitable temperature range, achieving the effect of keeping warm in winter and cool in summer.

[0042] like Figure 5 and Figure 6 As shown, further, a limiting structure 5 is provided on the shell, and the limiting structure 5 is located at the top of the shell and abuts against the lifting assembly 3. The limiting structure 5 is used to limit the travel of the insulation board 4.

[0043] Furthermore, the aforementioned limiting structure 5 includes a mounting ear 51, a nylon sleeve 52, a bolt 53, and a nut 54. The mounting ear 51 is connected to the housing, the nylon sleeve 52 is passed through the bolt 53, the bolt 53 is passed through the mounting ear 51 and is threadedly connected to the nut 54. The outer periphery of the nylon sleeve 52 contacts and abuts the lifting assembly 3. With this arrangement, the limiting structure 5 can limit the travel of the insulation board 4, preventing the insulation board 4 from deflecting during its upward and downward movement.

[0044] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referred to each other. The various embodiments of the utility model have been described above.
