Description

Technical Field

[0001] The invention belongs to the technical field of chemical equipment, and in particular relates to heat-insulating and corrosion-resistant chemical equipment. Background Art

[0002] The most commonly used type of equipment in chemical equipment is chemical storage tanks. Chemical storage tanks are used to store refined chemical substances such as acids, alkalis, alcohols, gases, and liquids. Due to the wide variety of storage materials and the diversity of storage conditions, there are different types of storage tanks. Because of its corrosion resistance, high strength, light weight, long life, flexible design, strong processability and other characteristics, FRP storage tanks have become a type of equipment that has attracted much attention in recent years.

[0030] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0031] Example

[0032] The following is combined with Figure 1-4 The present invention is further described:

[0033] The present invention provides a heat-insulating and corrosion-resistant chemical equipment 10 , comprising 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 body 120 which is covered on the tank body 110 .

[0035] The tank body 110 includes an inner glass fiber reinforced plastic layer 111, an insulation assembly 112, an outer glass fiber reinforced plastic layer 113, and a plurality of connecting columns 114, which are sequentially arranged from the inside to the outside. In this embodiment, the insulation assembly 112 includes a first insulation layer 1121 attached to the inner glass fiber reinforced plastic layer 111, and a second insulation layer 1122 attached to the outer glass fiber reinforced plastic layer 113. A vacuum layer 1123 is provided between the first insulation layer 1121 and the second insulation layer 1122. One end of the 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 arrangement of the above-mentioned inner and outer two-layer corrosion-resistant layer and thermal insulation interlayer enables the tank body 110 to have very excellent corrosion resistance and thermal insulation performance.

[0037] In this embodiment, the tank body 110 has a top wall 115, a bottom wall 116 and a side wall 117. The side wall 117 is provided with a feed port 1171 and a discharge port 1172. In this embodiment, the feed port 1171 is connected to a feed pipe 300, and the feed pipe 300 is provided with a first one-way valve 310. The discharge port 1172 is provided with a switch valve (not shown).

[0038] In this embodiment, the top wall 115, the bottom wall 116 and the side wall 117 of the tank body 110 are arranged to form a material storage space 118. The cover body 120 is connected to the top wall 115 and an overflow space 130 is formed between the cover body 120 and the top wall 115.

[0039] In this embodiment, the material 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 member 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 is provided with an overflow hole 1151, and the elastic member 210 and the partition cover 220 are arranged in the overflow space 130. The elastic member 210 is arranged above the overflow hole 1151, one end of the elastic member 210 is connected to the top wall 115, and the other end is connected to the partition cover 220, and the partition cover 220 can be in contact with or separated from the top wall 115. The elastic member 210 can be stretched upward under the pressure of the storage 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 storage material in the storage space 118 enters the overflow space 130 through the overflow hole 1151.

[0041] In this embodiment, the cover body 120 is provided with an overflow port 121 . The overflow port 121 is connected to an overflow pipe 400 , and the overflow pipe 400 is provided with a second one-way valve 410 . The stored material in the overflow space 130 can be discharged through the overflow port 121 .

[0042] In this embodiment, a guide groove 1152 is recessed on one side of the top wall 115 facing the cover body 120. The guide groove 1152 can be connected to the overflow hole 1151 and the overflow port 121, and the bottom surface of the guide groove 1152 forms an acute angle or an 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 body 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 body 120, the first solenoid valve 260 is connected to the overflow port 121, the second solenoid valve 270 is connected to the feed port 1171, and the distance detection sensor 240 is connected to the first solenoid valve 260 and the second solenoid valve 270, respectively.

[0044] The heat-insulating 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 body 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 is in contact with the top wall 115, and the storage space 118 is separated from the overflow space 130.

[0045] When the stored material is continuously input into the storage space 118 until the stored material contacts the top wall 115 of the tank body 110, the stored material then applies an upward pushing force to the elastic member 210 and the partition cover 220 through the overflow hole 1151 until the elastic member 210 is stretched, at which time the partition cover 220 leaves the top wall 115, and the storage space 118 is connected to the overflow space 130. The stored material enters the overflow space 130 from the storage space 118. At this time, the partition cover 220 moves upward, driving the positioning rod 230 to move upward. Since the positioning rod 230 contacts the distance detection sensor 240, the position of the distance detection sensor 240 does not change. At this time, the distance detection sensor 240 detects that the point where the positioning rod 230 contacts it has changed, and immediately sends a signal to the relay 250. After receiving the signal, the relay 250 sends the signal again to the first solenoid valve 260 and the second solenoid valve 270 respectively, so that the first solenoid valve 260 is closed and the second solenoid valve 270 is opened. At this time, the feed is closed and no more feed is made, the overflow pipe is opened, and the stored material in the overflow space 130 is quickly discharged. At this time, the elastic member 210 slowly moves downward to drive the partition cover 220 to move downward and contact 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 storage material, cut off the feed at the same time, and the storage material is not excessive, ensuring the safety of the equipment storage material.

[0046] In summary, the thermal insulation and corrosion-resistant chemical equipment 10 provided by the present invention has an ingenious structural design and excellent thermal insulation and corrosion resistance. It can also automatically discharge overflow storage materials and cut off the feed, so that the storage material is not excessive, thereby ensuring the safety of the equipment storage material.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
