Description

Technical Field

[0001] The invention relates to the technical field of chemical containers, and in particular to a petrochemical horizontal pressure container. Background Art

[0002] Petrochemical industry refers to the processing industry that uses petroleum and natural gas as raw materials to produce petroleum products and petrochemical products. During the processing, many kinds of materials are produced. When these materials are put into use, they need to be stored and transported in pressure vessels. In order to reduce transportation costs and better space utilization, most of them use one container during transportation, but they can be stored by dividing the space in the container. For example, a petrochemical horizontal pressure vessel disclosed in publication number CN118514986B is used to separate and store materials.

[0003] Different types of materials have different densities and volumes. If they are stored in separate pressure vessels, the weights of materials in different cavities will be different, making the center of gravity of the pressure vessel unbalanced. This may cause the material to be top-heavy during loading and transportation, which will not only affect the normal driving of the transport vehicle but also easily cause accidents.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The present invention will be further described below in conjunction with the embodiments.

[0034] Example: Refer to Figures 1 to 9 , a petrochemical horizontal pressure vessel, comprising: a base support 1 and a storage mechanism 2 fixed on the base support 1, a balancing mechanism 3 fixed in a solid-gas storage chamber, a trigger mechanism 4 fixed on a sealing tube 28, and also comprising an exhaust mechanism 5 fixed on a sealing tank body 21;

[0035] It should be noted that the container is divided into two chambers (hereinafter referred to as the solid-gas storage chamber and the liquid storage chamber), which can store different types of materials. Petrochemicals produce liquid materials such as gasoline, diesel or kerosene, as well as gas materials such as ethylene, propylene or benzene, all of which are insoluble in water. There are also synthetic solid materials such as resins, rubber or fibers, which cannot be stored together in the same chamber during transportation;

[0036] Through the cooperation between the storage mechanism 2 and the balancing mechanism 3, the cavity for storing materials can maintain a balanced overall center of gravity without being top-heavy, and the liquid therein will be sealed and filled in the cavity without shaking during transportation. Gas material is added to the container through the exhaust mechanism 5, which can not only clean up solid impurities in the gas material, but also moisten it so that it is no longer dry, and no harm will be caused by leakage during transportation.

[0037] Further explanation, in order to better store different materials, such as Figure 3 As shown, the storage mechanism 2 includes a sealed tank body 21 fixed on the base bracket 1, a separation plate 22 is fixed in the sealed tank body 21, a movable plate 24 slidably connected to the sealed tank body 21 is provided on one side of the separation plate 22, a telescopic rod 23 is fixed between the separation plate 22 and the movable plate 24, and the separation plate 22 divides the sealed tank body 21 into a liquid storage chamber and a solid-gas storage chamber, so that the liquid storage chamber and the solid-gas storage chamber are in a top-heavy state in the initial state so that the weight-increasing chamber can be used to add weight to the head to achieve head-foot balance, and the volume of the solid-gas storage chamber is smaller than the volume of the liquid storage chamber;

[0038] Then, even if solid materials are stored in the solid-gas storage chamber, the weight of the solid or gas materials in the solid-gas storage chamber will not be much greater than the weight of the liquid materials in the liquid storage chamber. Even if the gas material is pressurized to liquefy it, this will be the case due to the volume difference. Two feed flanges 25 are fixed to the upper side of the sealed tank body 21, and two discharge flanges 26 are fixed to the lower side of the sealed tank body 21. Pressure measuring devices 27 are also symmetrically fixed to the lower side of the sealed tank body 21. The two pressure measuring devices 27 can better measure the weight of the two ends of the sealed tank body 21, which is convenient for the subsequent adjustment of the weight distribution. A sealing tube 28 is fixed in the sealed tank body 21.

[0039] Further explanation, in order to ensure the overall weight balance of the container, Figure 3As shown, a balancing mechanism 3 is fixed in the solid-gas storage chamber, and the balancing mechanism 3 includes a sealed shell 31 fixed in the sealed tank body 21, and a weight-added chamber is formed between the outer surface of the sealed shell 31 and the inner wall of the solid-gas storage chamber, and the weight-added chamber is connected to the sealing tube 28 (through a special-shaped flow channel, and the connection state is not shown in the figure). When the weight of the material stored in the solid-gas storage chamber is less than that of the material in the liquid storage chamber, the liquid material in the liquid storage chamber can be discharged into the weight-added chamber, so that the weight at both ends of the sealed tank body 21 remains relatively balanced;

[0040] Then, an inclined sleeve 32 is fixed in the sealed shell 31, and an inner wall of the inclined sleeve 32 is symmetrically provided with an inclined surface 33. The inclined surface 33 and the inclined sleeve 32 are provided for better unloading so that solid materials will not remain in the container. The feed flange 25 located in the solid-gas storage chamber is connected to the sealed shell 31, and a connecting pipe 34 is connected to the upper side of the weight-increasing chamber. The weight-increasing chamber is connected to the liquid storage chamber through the connecting pipe 34. A one-way valve is provided in the connecting pipe 34. When unloading, the sealing between the weight-increasing chamber and the liquid storage chamber is utilized, and the liquid material flowing into the weight-increasing chamber is pumped out by a water pump, and there will be no residual material.

[0041] Specifically, after the material storage is completed, the two pressure measuring devices 27 will measure the weight of the materials stored in the solid-gas storage chamber and the liquid storage chamber, and then start the telescopic rod 23 to push the movable plate 24 to move. The movable plate 24 will push the liquid material in the liquid storage chamber to flow, so that it flows from the sealing tube 28 to the weight-increasing chamber. When the pressures of the two pressure measuring devices 27 remain relatively balanced, the movement of the movable plate 24 can be stopped. At this time, the liquid material will also remain in a sealed and filled state in the liquid storage chamber.

[0042] Further explanation, in order to facilitate the observation of the liquid level in the cavity, as shown in FIG. Figure 4As shown, the trigger mechanism 4 includes a support plate 41 fixed to the upper end of the sealing tube 28, an arc-shaped hole 42 is opened in the middle of the upper end of the support plate 41, and the arc-shaped hole 42 is connected to the sealing tube 28. An elastic member 43 is fixed in the arc-shaped hole 42, and a conical sleeve 44 is fixed in the support plate 41. A conical block 45 adapted to the conical sleeve 44 is fixed at the upper end of the elastic member 43. When there is no impact force of the liquid material, the elastic member 43 will push the conical block 45 to fit the inner wall of the conical sleeve 44, so that the arc-shaped hole 42 maintains an airtight sealing state. The upper end of the support plate 41 is fixed There is at least one elastic telescopic tube 46, and a sealing sleeve 47 is fixed to the telescopic end of the elastic telescopic tube 46. The sealing sleeve 47 is located directly above the conical sleeve 44. When the container is in the initial state, the sealing sleeve 47 hermetically seals the conical sleeve 44. That is to say, when liquid material is added to the liquid storage chamber, the liquid material will not directly enter the weight-increasing chamber from the inclined sleeve 32 and the sealing tube 28, ensuring that the equipment has the function of balancing the weight at both ends. A support frame 48 is fixed in the sealed tank body 21, and a float assembly 49 compatible with the sealing sleeve 47 is provided above the sealing sleeve 47.

[0043] To further explain, in order to cooperate with the storage mechanism 2 and the balance mechanism 3 to trigger, as Figure 5 and Figure 6 As shown, the float assembly 49 includes a float plate 491 slidably connected to the end surface of the support frame 48, an air bag 492 is evenly fixed to the lower end of the float plate 491, and the air bag 492 is filled with gas, so that the float plate 491 can float on the liquid surface, and a take-up roller 493 is fixed to the middle part of the lower end of the float plate 491, and a torsion spring is provided at the shaft connection of the take-up roller 493, so that the connecting rope 494 can be rewound on the inner wall of the take-up roller 493, and the inner wall of the take-up roller 493 is wound with the connecting rope 494, and a pressing column 495 is also fixed to the lower end of the float plate 491, and the pressing column 495 is located just above the sealing sleeve 47;

[0044] Then, two bracket blocks 496 are fixed to the upper end of the support plate 41, and an elastic member 497 is provided between the two bracket blocks 496. A card roller 498 is fixed to one end of the elastic member 497 close to the sealing sleeve 47. The outer surface of the card roller 498 penetrates the sealing sleeve 47, and the card roller 498 limits the sealing sleeve 47. When the floating plate 491 moves upward, the connecting rope 494 therein will gradually unwind. When the connecting rope 494 becomes taut with the movement of the floating plate 491, the filling of liquid materials can be stopped to ensure that the liquid materials in the container are not in a full state, so as to facilitate the adjustment of the weight balance of the sealed tank body 21. The card roller 498 is fixedly connected to one end of the connecting rope 494;

[0045] Specifically, when the liquid material enters the liquid storage chamber, under the buoyancy of the airbag 492, the float plate 491 will move upward with the liquid level, and the take-up roller 493 will also move upward with the float plate 491. During this process, the connecting rope 494 wrapped around its surface will gradually be untangled. The floating height of the float plate 491 can ensure that not too much material is stored in the container, so that the storage work can be better carried out. Wait until the float plate 491 moves so that the connecting rope 494 remains taut and then stop, completing the storage work.

[0046] Further, in order to clean and moisten the dry gas material entering the container, such as Figure 7 and Figure 8 As shown, it also includes an exhaust mechanism 5 fixed on the sealed tank body 21, and the exhaust mechanism 5 includes a rectangular shell 51 fixed on the sealed tank body 21, and the bottom wall of the rectangular shell 51 is symmetrically provided with a water outlet 50, and the upper end of the rectangular shell 51 is connected to a water tank 52, and an air intake assembly 53 is arranged in the rectangular shell 51, and a reciprocating screw rod 54 driven by a motor is rotatably connected in the rectangular shell 51, and a cleaning plate 55 is sleeved on the outer surface of the reciprocating screw rod 54, and an arc plate 55 is symmetrically fixed on the bottom wall of the rectangular shell 51. 56, the two side surfaces of the cleaning plate 55 are respectively attached to the surfaces of the two arc-shaped plates 56, and the two arc-shaped plates 56 are provided with a limit plate 57 fixed to the inner wall of the rectangular shell 51 on the side away from each other, and the two water outlets 50 are respectively located below the two limit plates 57, and the lower end of the limit plate 57 is rotatably connected with a filter plate 58, and a torsion spring is provided at the connection between the filter plate 58 and the limit plate 57, and the upper end of the rectangular shell 51 is connected with a U-shaped tube 59, and the rectangular shell 51 is connected with the solid-gas storage chamber through the U-shaped tube 59;

[0047] Specifically, the gas material entering the rectangular shell 51 needs to be insoluble in water, and then flows from the water in the rectangular shell 51 to the U-shaped tube 59, and finally enters the solid-gas storage chamber through the U-shaped tube 59. This process can wash the gas material with water, and while cleaning the solid impurities in the gas material, it can also moisten it so that it no longer remains dry. It should be noted that after the gas material enters the solid-gas storage chamber, it will be converted into a high-pressure liquid for transportation. The specific principle is the existing technology and will not be explained here.

[0048] To further illustrate, in order to ensure the overall sealing performance of the sealed tank 21, Fig. 9 As shown, the air intake assembly 53 includes a storage tube 531 fixed to the bottom wall of the rectangular shell 51, a telescopic rod 532 is fixed inside the storage tube 531, an air intake pipe 533 penetrating the rectangular shell 51 is provided above the storage tube 531, a piston rod 534 is fixed to the telescopic end of the telescopic rod 532, and the telescopic rod 532 is activated to push the piston rod 534 to move upward, so that the air intake pipe 533 is in an airtight connection state, and then the gas material can be filled into the rectangular shell 51 through the air intake pipe 533.

[0049] The working principle of the present invention is as follows: two different materials are stored in the solid-gas storage chamber and the liquid storage chamber through the feed flange 25, and the gas material needs to be started by starting the telescopic rod 2 532 to push the piston rod 534 to move upward, so that the air inlet pipe 533 is in an airtight connection state, and then the gas material is added into the rectangular shell 51 through the air inlet pipe 533. The gas material entering the rectangular shell 51 is insoluble in water, and then flows from the water in the rectangular shell 51 to the U-shaped tube 59, and finally enters the solid-gas storage chamber through the U-shaped tube 59. This process can be used for gas materials. The material is washed with water, and while cleaning the solid impurities in the gas material, it can also moisten it so that it is no longer dry, and will not cause harm due to leakage during transportation. After washing, solid impurities will remain in the rectangular shell 51, and the impurities will float on the water surface. The reciprocating screw 54 is driven by a motor to rotate, and the rotating reciprocating screw 54 will drive the cleaning plate 55 to move up and down, pushing the impurities floating on the water surface to between the arc plate 56 and the limit plate 57 on both sides. When more impurities are stored, they can be discharged from the rectangular shell 51 through the two water outlets 50;

[0050] When the liquid material enters the liquid storage chamber, under the buoyancy of the airbag 492, the float plate 491 will move upward with the liquid level, and the take-up roller 493 will also move upward with the float plate 491. In this process, the connecting rope 494 wound on its surface will gradually unwind. The liquid level can be known by the floating height of the float plate 491, so that the storage work can be better performed. When the float plate 491 moves and the connecting rope 494 remains in a taut state, it can be stopped, and the storage work is completed. Due to the different densities of the materials, the weights in the solid-gas storage chamber and the liquid storage chamber are different, which will cause a top-heavy situation during transportation, affecting the driving of the transport vehicle. After the material storage is completed, the two pressure measuring devices 27 will measure the weight of the materials stored in the two chambers;

[0051] Then start the telescopic rod 23 to push the movable plate 24 to move. The movable plate 24 will push the liquid material in the liquid storage chamber to flow, so that the floating plate 491 continues to move upward, and the taut connecting rope 494 will pull the card roller 498 to move. The card roller 498 will compress the elastic part 2 497 during the movement, and at the same time release the limit on the sealing sleeve 47, and the elastic telescopic tube 46 will be able to push the sealing sleeve 47 to move upward. During this process, the movable plate 24 will continue to push the liquid material to move. Under the action of the impact force of the liquid, the conical block 45 therein will move downward, and the liquid material will enter the weight-increasing chamber from the sealing tube 28. When the pressure of the two pressure measuring devices 27 remains relatively balanced, the movement of the movable plate 24 can be stopped. At this time, the liquid material will remain in a sealed and filled state in the liquid storage chamber, and will not shake during transportation.

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
