Description

Technical Field

[0001] The utility model relates to the technical field of chemical liquid storage, in particular to a storage tank for volatile petrochemical liquid products. Background Art

[0002] Petrochemical liquid transportation is an indispensable part of the petrochemical industry chain, involving a wide variety of products, including crude oil, refined oil, chemical solvents, lubricants, etc. This document aims to comprehensively analyze the background technology of petrochemical liquid transportation, covering aspects such as liquid properties, transportation methods, safety and environmental protection measures, regulatory policies, and technology development trends. Petrochemical liquid products contain a large number of volatile varieties. During the storage and transportation of these liquids, the volatile gases will cause the pressure in the tank to increase. Once there is a violent shake, it may cause damage to the tank or even explosion.

[0003] According to Chinese patent announcement number: CN210913815U, a volatile petrochemical liquid product storage tank is disclosed, including a tank body and a base placed under the tank body, a cooling mechanism is arranged outside the tank body, legs are installed at the four corners of the bottom of the base, the bottom of the tank body is connected to the base through an anti-shake mechanism, the anti-shake mechanism includes two pad legs symmetrically fixed at the bottom of the left and right ends of the tank body, the bottoms of the two pad legs are fixedly connected to support rods, two through holes are symmetrically opened on the base for the two support rods to pass through respectively, the lower ends of the two support rods are sequentially sleeved with compression springs and anti-slip rings after passing through the base, and the anti-slip rings are fixedly welded to the outside of the support rods, the upper end of the compression spring is fixedly connected to the bottom of the base, the lower end of the compression spring is fixedly connected to the upper end face of the anti-slip ring, and a stabilization mechanism is symmetrically arranged between the tank body and the base. The anti-shake mechanism can provide shock-absorbing and buffering treatment for the tank placed on the vehicle body during transportation, so as to prevent the tank from being violently shaken by the shaking of the vehicle body during transportation, and to avoid damage or even explosion of the tank to the greatest extent, thus ensuring transportation safety. However, when using the above device, only the tank placed on the vehicle body can be shock-absorbing and buffered. During transportation, a large amount of gas will still be stored between the liquid and the top wall of the tank body, and the air pressure inside the tank body will increase, increasing the transportation risk.

[0004] Therefore, when using the above device, a large amount of gas will still be stored between the top wall of the tank body, and the air pressure inside the tank body will increase, increasing the transportation risk. Utility Model Content

[0013] There are multiple sliding blocks, which are symmetrically fixed on the second floating plate.

[0014] Further preferably, sliding grooves having sizes corresponding to the positions of the sliding blocks are symmetrically arranged on both sides of the first floating plate.

[0015] Compared with the prior art, the utility model has the following advantages: by setting the first floating plate and the second floating plate, when transporting liquid that is easy to volatilize, the first floating plate and the second floating plate move up and down with the liquid surface, isolating the space between the liquid surface and the top wall of the tank body, thereby effectively reducing the volatilization of the liquid, reducing the air pressure inside the tank body, and reducing the transportation risk; by setting the breathing valve and the absorption shell, when the liquid volatilizes too much gas, the breathing valve transports the gas to the inside of the absorption shell, thereby reducing the air pressure inside the tank body, thereby improving the safety of transportation, and the absorption shell adsorbs the gas inside, thereby recovering the volatilized gas, reducing economic losses.

DETAILED DESCRIPTION

[0020] A volatile petrochemical liquid product storage tank disclosed in the prior art comprises a tank body and a base placed under the tank body, a cooling mechanism is arranged outside the tank body, legs are installed at the four corners of the bottom of the base, the bottom of the tank body is connected to the base through an anti-shake mechanism, the anti-shake mechanism comprises two pad legs symmetrically fixed at the bottom of the left and right ends of the tank body, the bottoms of the two pad legs are fixedly connected with support rods, two through holes are symmetrically opened on the base for the two support rods to be inserted respectively, the lower ends of the two support rods are sequentially sleeved with compression springs and anti-slip rings after passing through the base, and the anti-slip rings are fixedly welded outside the support rods, the upper end of the compression spring is fixedly connected to the bottom of the base, and the lower end of the compression spring is fixedly connected to the upper end surface of the anti-slip ring, and a stabilization mechanism is symmetrically arranged between the tank body and the base. The anti-shake mechanism can be set to perform shock-absorbing and buffering treatment on the tank body placed on the vehicle body during transportation, so as to avoid the violent shaking of the tank body caused by the shaking of the vehicle body during the road, and to avoid damage or even explosion of the tank body to the greatest extent, so as to ensure transportation safety. However, when using the above device, only the tank placed on the vehicle body can be shock-absorbing and buffered. During transportation, a large amount of gas will still be stored between the liquid and the top wall of the tank, and then the air pressure inside the tank will increase, increasing the transportation risk.

[0021] Therefore, when using the above device, a large amount of gas will still be stored between the top wall of the tank body, and the air pressure inside the tank body will increase, increasing the transportation risk.

[0022] In response to the above technical problems, the present application has made the following designs and ideas: In order to solve the problems existing in the prior art, it is envisaged that a certain isolation mechanism can have a better effect in reducing liquid volatilization than the anti-shake mechanism in the prior art, thereby achieving the purpose of safely transporting liquids.

[0023] The following is combined with Figures 1 to 3 The utility model is further introduced in detail.

[0024] A storage tank for volatile petrochemical liquid products, such as Figure 1As shown, it includes a tank body 1 and an injection port 2 arranged at one end of the upper part of the tank body 1, and also includes: breathing valves 3 symmetrically fixed to both sides of the upper part of the tank body 1 at equal intervals, and an absorption shell 4 is commonly installed on the upper part of multiple breathing valves 3. Further, the absorption shell 4 is used to store volatile gases of the liquid, and the absorption shell 4 is provided with a material for adsorbing volatile gases. Baffle plates 5 are evenly arranged inside the tank body 1. Further, the baffle plates 5 are used to alleviate the shaking amplitude of the liquid inside the tank body 1. Floating components 6 are movably installed on both sides of the baffle plate 5. Communication ports 7 are symmetrically opened on both sides of the baffle plate 5. The floating component 6 includes a first floating plate 62 slidably installed at the middle position of both sides of the baffle plate 5 and a second floating plate 66 slidably installed at both end positions of both sides of the baffle plate 5.

[0025] By setting the first floating plate 62 and the second floating plate 66, when transporting liquid that is easy to volatilize, the first floating plate 62 and the second floating plate 66 move up and down with the liquid surface, isolating the space between the liquid surface and the top wall of the tank body 1, thereby effectively reducing the volatilization of the liquid, reducing the internal air pressure of the tank body 1, and reducing the transportation risk. By setting the breathing valve 3 and the absorption shell 4, when the liquid volatilizes too much gas, the breathing valve 3 transports the gas to the inside of the absorption shell 4, thereby reducing the air pressure inside the tank body 1, thereby improving the safety of transportation, and the absorption shell 4 adsorbs the gas inside, thereby recovering the volatilized gas, reducing economic losses.

[0026] Specifically, Figure 2 and Figure 3 As shown, the floating assembly 6 also includes:

[0027] There are two first slide rails 61 , which are symmetrically installed at the middle positions of both sides of the baffle plate 5 , and one end of the first floating plate 62 is slidably connected to the first slide rail 61 .

[0028] There are multiple second slide rails 65, which are symmetrically installed at both ends of the baffle plate 5. One end of the second floating plate 66 is slidably connected to the second slide rail 65. Furthermore, the shape of the second slide rail 65 is similar to the shape of both sides of the tank body 1. Furthermore, the tank body 1 is elliptical.

[0029] Furthermore, when transporting liquids that are easily volatile, the liquid will shake during transportation, and the distance between the liquid surface and the first floating plate 62 and the second floating plate 66 will change. The gas volatilized from the liquid will fill the space between the liquid surface and the first floating plate 62 and the second floating plate 66. Then, when the liquid shakes, the first floating plate 62 and the second floating plate 66 will also move up and down driven by the gas, thereby effectively isolating the space between the liquid surface and the top wall of the tank body 1, thereby effectively reducing the volatilization of the liquid.

[0030] Specifically, Figure 2 and Figure 3As shown, the floating assembly 6 also includes:

[0031] The first magnetic block 63 is fixedly connected to one end of the first floating plate 62 close to the first slide rail 61 . Specifically, the magnetic pole of the first magnetic block 63 is a positive pole.

[0032] The second magnetic block 64 is fixedly connected to both sides of the upper part of the first slide rail 61 , and the installation position of the second magnetic block 64 corresponds to the installation position of the first magnetic block 63 . Specifically, the magnetic pole of the second magnetic block 64 is positive.

[0033] There are multiple sliding blocks 67 , which are symmetrically fixed on the second floating plate 66 .

[0034] Furthermore, when the volatilized gas from the liquid drives the first floating plate 62 and the second floating plate 66 to move upward, the two second floating plates 66 approach each other while moving on the second slide rail 65. At the same time, when the first floating plate 62 rises, the second magnetic block 64 and the first magnetic block 63 approach each other, and like charges repel each other. The first floating plate 62 and the second floating plate 66 move downward again. When the volatilized gas from the liquid is large, the distance between the first floating plate 62 and the second floating plate 66 and the liquid surface is limited under the action of the second magnetic block 64 and the first magnetic block 63.

[0035] Specifically, Figure 2 and Figure 3 As shown, sliding grooves corresponding to the position and size of the sliding block 67 are symmetrically arranged on both sides of the first floating plate 62. Further, when the first floating plate 62 and the second floating plate 66 move up and down, the flexibility between the first floating plate 62 and the second floating plate 66 is improved.

[0036] How it works

[0037] When in use, liquid is injected into the tank body 1 through the injection port 2. When the liquid volatilizes gas, the first floating plate 62 and the second floating plate 66 isolate the gas from the top wall of the tank body 1. When the liquid surface shakes, the volatilized gas drives the first floating plate 62 and the second floating plate 66 to move up and down on the first slide rail 61 and the second slide rail 65. When the first floating plate 62 and the second floating plate 66 move up and down, the two second floating plates 66 move on the second slide rail 65 while approaching each other. At the same time, when the first floating plate 62 rises, the second magnetic block 64 and the first magnetic block 63 approach each other. Like charges repel each other, and the first floating plate 62 and the second floating plate 66 move downward again. When the liquid volatilizes more gas, the distance between the first floating plate 62 and the second floating plate 66 and the liquid surface is limited under the action of the second magnetic block 64 and the first magnetic block 63.

[0038] This specific embodiment is merely an explanation of the utility model, and it is not a limitation of the utility model. After reading this specification, those skilled in the art can make non-creative modifications to the embodiment as needed, but as long as it is within the protection scope of the utility model, it is protected by the patent law.
