[0023] The present invention will be further explained below in conjunction with specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0024] like Figure 1 and Figure 4 As shown, a steel-lined plastic storage tank with good thermal insulation effect includes a tank body 1, an anti-corrosion layer 2, a jacket 3, a heating box 4, a circulating pump 5 and a solar collector 6. The tank body 1 is a horizontal cylindrical tank. The tank body 1 is made of carbon steel or stainless steel. The anti-corrosion layer 2 is made of polypropylene or polyethylene and other materials. It is combined with the inside of the tank body 1 by rotational molding. The steel mesh is welded to the inner wall of the tank body 1 and then rotationally molded to firmly connect the anti-corrosion layer 2 to the tank body 1. Due to the provision of the anti-corrosion layer 2, the entire storage tank is corrosion-resistant and leak-proof, sturdy and durable, and is suitable for storing various acid and alkali solutions. The jacket 3 is rectangular as a whole and surrounds the outside of the tank body 1. A accommodating chamber 31 is provided in the jacket 3. The accommodating chamber 31 is used to accommodate a heat exchange medium. In this embodiment, the heat exchange medium is water. An insulating layer 32 can also be provided outside the jacket 3. The insulating layer 32 is made of existing insulating materials and surrounds the outside of the jacket 3 to insulate the outside of the jacket 3. One end of the jacket 3 is connected to the heating box 4 and the circulating pump 5. The heating box 4 is arranged at one end of the jacket 3. The heating box 4 is connected to the accommodating chamber 31 through a first pipeline 71. The inlet end of the first pipeline 71 is arranged on the jacket 3 at the other end away from the end where the heating box 4 is located. The circulating pump 5 is connected to the heating box 4 through a pipeline. The circulating pump 5 is connected to the accommodating chamber 31 through a second pipeline 72. The outlet end of the second pipeline 72 is arranged on the jacket at one end close to the circulating pump 5. Under the action of the circulating pump 5, the accommodating chamber The water in 31 enters the heating box 4 from the first pipeline 71. The heating box 4 is provided with a plurality of electric heaters 41. The electric heaters 41 heat the water. The heated water returns to the containing chamber 31 through the second pipeline 72. In winter outdoor places, the liquid stored in the storage tank needs to be kept warm. For example, when storing liquid alkali, the liquid alkali will become viscous and have poor fluidity when the temperature is low, and it is easy to volatilize and decompose when the temperature is too high. Therefore, in order to ensure the stability and use effect of the liquid alkali, it is necessary to maintain a suitable temperature range during storage, generally at 15°C-30°C. However, in winter outdoor, the general storage tank cannot maintain this temperature. In this embodiment, the water in the heating jacket 3 of the heating box 4 can well keep the storage tank warm. At the same time, since the electric heater 41 does not directly heat the liquid in the storage tank, the heating method is mild, and the storage tank can be suitable for more liquid insulation storage. The tank body 1 is provided with a stirrer 13. The stirrer 13 adopts an existing electric stirrer. The stirring paddle of the stirrer 13 is located in the tank body 1, which is used to stir the liquid to make the liquid in the storage tank flow and heat evenly.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, the solar collector 6 is arranged on the outer top of the jacket 3. The solar collector 6 includes a shell 61, an insulation layer 62, a heat absorbing plate 63, a heat exchange tube 64 and a light-transmitting plate 65. The shell 61 is a rectangular shell. The heat absorbing plate 63 is arranged in the shell 61 and faces outward to absorb solar energy. The heat exchange tube 64 is provided with a plurality of copper tubes arranged side by side in the shell 61 and connected to the heat absorbing plate 63. The heat exchange tube 64 is used for water flow. The insulation layer 62 is arranged between the heat absorbing plate 63 and the shell 61 to prevent heat loss. The light-transmitting plate 65 is used to block the outside of the heat absorbing plate 63 to block dust. The light-transmitting plate 65 adopts high-transmittance glass and does not block sunlight. Under sunlight, the heat absorbing plate 63 and the heat exchange tube 64 heat the water in the heat exchange tube 64. The second pipeline 72 is connected to the inlet end of the heat exchange tube 64 through the third pipeline 73, and the third pipeline 73 includes a first hose. The outlet end of the heat exchange tube 64 is connected to the second pipeline 72 through the fourth pipeline 74, and the fourth pipeline 74 includes a second hose. Since the solar collector 6 is connected to the outside through the hose, the hose has a certain length, which facilitates the overall movement of the solar collector 6. A first on-off valve 81 is provided on the second pipeline 72, a second on-off valve 82 is provided on the third pipeline 73, and a third on-off valve 83 is provided on the fourth pipeline 74. When the solar collector 6 is not needed, the first on-off valve 81 is opened, the second on-off valve 82 and the third on-off valve 83 are closed, and the water transported by the circulation pump 5 directly returns to the accommodating chamber 31; when the solar collector 6 is needed to heat the water, the first on-off valve 81 is closed, the second on-off valve 82 and the third on-off valve 83 are opened, and the water transported by the circulation pump 5 enters the accommodating chamber 31 through the solar collector 6. When there is sufficient sunshine in winter, the electric heater 41 may not work, and the solar collector 6 is directly used for heating to save energy.

[0026] like Figure 1 , Figure 4 and Figure 5 As shown, a hinge shaft 66 is provided at one end of the shell 61, and the shell 61 is hinged to the jacket 3 through the hinge shaft 66. An adjusting rod 91 corresponding to the position of the solar collector 6 is connected to the jacket 3. The adjusting rod 91 is arranged beside the shell 61. A slide groove 901 is provided on the adjusting rod 91. A positioning bolt 92 can slide in the slide groove 901. A plurality of positioning holes 601 corresponding to the positioning bolt 92 are provided on the side of the shell 61. The plurality of positioning holes 601 are arranged in a row along the length direction of the shell 61. The shell 61 is pushed upward, and the positioning bolt 92 is threadedly connected to the positioning hole 601 after passing through the slide groove 901. The shell 61 can be connected to the adjusting rod 91. The positioning bolt 92 is connected to the positioning holes 601 at different positions to fix the shell 61 at different angles, so that the inclination angle of the solar collector 6 can be adjusted, so that the solar collector 6 can be directly exposed to sunlight and absorb more heat.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
