They are used to store refined chemical substances such as acids, alkalis, alcohols, gases, and liquids. Due to the wide variety of stored materials and diverse storage conditions, different types of storage tanks are available. Fiberglass storage tanks have become a popular choice in recent years due to their corrosion resistance, high strength, light weight, long service life, flexible design, and strong processability.
[0003] Fiberglass storage tanks are a type of fiberglass product. They are a new type of composite material mainly made of glass fiber as a reinforcing agent and resin as a binder, which is manufactured by winding the fiberglass using a microcomputer-controlled machine.

[0031] Example
[0032] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described as follows:
[0033] This utility model provides a heat-insulating and corrosion-resistant chemical equipment 10, including a storage tank body 100 and an automatic overflow component 200.
[0034] The storage tank body 100 includes a tank body 110 and a cover 120 covering the tank body 110.
[0035] The tank body 110 includes an inner fiberglass layer 111, an insulation component 112, an outer fiberglass layer 113, and multiple connecting columns 114 arranged sequentially from the inside out. In this embodiment, the insulation component 112 includes a first insulation layer 1121 attached to the inner fiberglass layer 111 and a second insulation layer 1122 attached to the outer fiberglass layer 113. A vacuum layer 1123 is provided between the first insulation layer 1121 and the second insulation layer 1122. One end of each connecting column 114 is connected to the first insulation layer 1121, and the other end passes through the vacuum layer 1123 and is connected to the second insulation layer 1122.
[0036] The aforementioned arrangement of the inner and outer corrosion-resistant layers and the insulation interlayer gives the tank 110 excellent corrosion resistance and insulation performance.
[0037] In this embodiment, the tank 110 has a top wall 115, a bottom wall 116, and a side wall 117. The side wall 117 has an inlet 1171 and an outlet 1172. In this embodiment, the inlet 1171 is connected to an inlet pipe 300, and the inlet pipe 300 is equipped with a first one-way valve 310. The outlet 1172 is equipped with a switch valve (not shown).
[0038] In this embodiment, the top wall 115, bottom wall 116, and side wall 117 of the tank 110 form a storage space 118. The cover 120 is connected to the top wall 115 and forms an overflow space 130 between the cover 120 and the top wall 115.
[0039] In this embodiment, the storage space 118 and the overflow space 130 can be separated or connected by the automatic overflow assembly 200. Specifically, the automatic overflow assembly 200 includes an elastic element 210, a partition cover 220, a positioning rod 230, a distance detection sensor 240, a relay 250, a first solenoid valve 260, and a second solenoid valve 270.
[0040] The top wall 115 has an overflow hole 1151, and an elastic element 210 and a partition cover 220 are disposed in the overflow space 130. The elastic element 210 is disposed above the overflow hole 1151, with one end connected to the top wall 115 and the other end connected to the partition cover 220. The partition cover 220 can contact or separate from the top wall 115. The elastic element 210 can be stretched upward under the pressure of the stored material, thereby driving the partition cover 220 away from the top wall 115. At this time, the storage space 118 is connected to the overflow space 130, and the stored material in the storage space 118 enters the overflow space 130 through the overflow hole 1151.
[0041] In this embodiment, the cover 120 has an overflow port 121. The overflow port 121 is connected to an overflow pipe 400, and the overflow pipe 400 is equipped with a second one-way valve 410. The material stored in the overflow space 130 can be discharged through the overflow port 121.
[0042] In this embodiment, a guide groove 1152 is recessed on the side of the top wall 115 facing the cover 120. The guide groove 1152 can communicate with the overflow hole 1151 and the overflow port 121. The bottom surface of the guide groove 1152 forms an acute or obtuse angle with the axis of the storage tank body 100. The stored material can eventually flow into the guide groove 1152 and automatically flow to the overflow port 121 for discharge.
[0043] In this embodiment, one end of the positioning rod 230 is connected to the partition cover 220, and the other end passes through the cover 120 and contacts the distance detection sensor 240. The distance detection sensor 240 and the relay 250 are connected to the outside of the cover 120. The first solenoid valve 260 is connected to the overflow port 121, and the second solenoid valve 270 is connected to the feed port 1171. The distance detection sensor 240 is connected to the first solenoid valve 260 and the second solenoid valve 270 respectively.
[0044] The thermal insulation and corrosion resistant chemical equipment 10 provided in this embodiment is used as follows: the stored material enters the storage space 118 of the tank 110 through the feed pipe 300. At this time, the first one-way valve 310 and the first solenoid valve 260 are opened, the partition cover 220 contacts the top wall 115, and the storage space 118 is separated from the overflow space 130.
[0045] As the stored material is continuously fed into the storage space 118 until it contacts the top wall 115 of the tank 110, the material then exerts an upward pushing force on the elastic element 210 and the partition cover 220 through the overflow hole 1151, stretching the elastic element 210. At this point, the partition cover 220 moves away from the top wall 115, and the storage space 118 connects with the overflow space 130. The stored material then enters the overflow space 130 from the storage space 118. At this time, as the partition cover 220 moves upward, it drives the positioning rod 230 to move upward. Since the positioning rod 230 is in contact with the distance detection sensor 240, and the position of the distance detection sensor 240 has not changed, the distance detection sensor 240 detects that the point of contact between the positioning rod 230 and the sensor has changed. It immediately sends a signal to the relay 250. After receiving the signal, the relay 250 sends signals to the first solenoid valve 260 and the second solenoid valve 270 respectively, so that the first solenoid valve 260 closes and the second solenoid valve 270 opens. At this time, the feeding is stopped, the overflow pipe opens, and the stored material in the overflow space 130 is quickly discharged. At this time, the elastic element 210 slowly moves downward, driving the partition cover 220 downward and contacting the top wall 115. At this time, the storage space 118 is separated from the overflow space 130. The whole process can automatically discharge the overflow stored material, cut off the feeding, prevent the storage of material from being excessive, and ensure the safety of the equipment's storage.
[0046] In summary, the thermal insulation and corrosion resistant chemical equipment 10 provided by this utility model has an ingenious structural design, excellent thermal insulation and corrosion resistance, and can automatically discharge overflow storage material, cut off the feed, prevent over-storage, and ensure the safety of the equipment's storage.
[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
