Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and specifically relates to a skid-mounted equipment with a storage unit for conveying and supplying. Background Art

[0002] A skid-mounted equipment is a form of combination of an equipment frame and the overall equipment. Each part of the unit is installed on a large integral base, which is skid-mounted and convenient for overall movement by a crane or a forklift. In chemical production, for example, in the cryogenic separation process of petroleum cracking gas, some highly viscous liquid materials such as tar are generated. When processing these highly viscous liquid materials, storage and ultra-long-distance transportation are often required. In the traditional technology, they are stored in an oil tank, and when transporting, they are driven by a liquid pump suitable for transporting highly viscous liquids. However, the transportation process is affected by the remaining amount in the oil tank. Especially for ultra-long-distance transportation, before the liquid material reaches the destination equipment, if the liquid material in the oil tank has been consumed, at this time the liquid pump can no longer continue to transport the liquid material for pushing at the end, and the liquid material will stay in the long-distance pipeline. Therefore, there are certain limitations. Summary of the Invention

[0003] The purpose of the present invention is to provide a skid-mounted equipment with a storage unit for conveying and supplying, so as to solve the problems proposed in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A skid-mounted equipment with a storage unit for conveying and supplying, including a skid-mounted frame, and a storage unit, a compressed gas tank and a self-adaptive control valve installed in the skid-mounted frame. The storage unit is used for storing liquid materials; The compressed gas tank stores compressed gas and communicates and inputs the compressed gas into the self-adaptive control valve. The self-adaptive control valve is provided with a pressing pipeline and a continuous conveying pipe, and the self-adaptive control valve can control the communication state between the pressing pipeline and the continuous conveying pipe and the compressed gas tank; The storage unit is communicatively provided with a replacement switching pipe, and a first check valve is arranged on the replacement switching pipe. The first check valve enables the liquid material in the storage unit to flow out unidirectionally through the replacement switching pipe; The pressing pipeline is communicated with the upper part of the storage unit. When the self-adaptive control valve controls the compressed gas tank and the pressing pipeline to be communicated, the pressing pipeline inputs compressed gas into the storage unit, so that the liquid material in the storage unit is pressed out into the replacement switching pipe; The continuous conveying pipe is communicatively crossed with the side wall of the replacement switching pipe, and the communication port between the continuous conveying pipe and the replacement switching pipe is downstream of the first check valve. When the self-adaptive control valve controls the compressed gas tank and the continuous conveying pipe to be communicated, the continuous conveying pipe inputs compressed gas into the replacement switching pipe to drive the liquid material in the replacement switching pipe to be conveyed and moved.

[0005] A liquid flowmeter is provided on the replacement switching pipe to count the liquid flowing through the replacement switching pipe; a central vertical pipe is vertically arranged inside the storage unit, a liquid inlet groove hole is opened at the lower end position of the central vertical pipe, and the upper end of the central vertical pipe is communicated with the replacement switching pipe.

[0006] A pressure main chamber, a pressing side chamber and a conveying side chamber are provided in the self-adaptive control valve. The compressed air tank is communicated with the pressure main chamber, the pressing pipeline is communicated with the pressing side chamber, and the continuous conveying pipe is communicated with the conveying side chamber.

[0007] Sealing matching eaves, a closing plug disc, a plug disc shaft and a telescopic control cylinder are symmetrically arranged on both sides of the pressure main chamber; the opening and closing control is carried out between the sealing matching eaves and the closing plug disc through axial movement. A plug disc shaft is arranged on the closing plug disc, and the other end of the plug disc shaft extends out of the self-adaptive control valve. The plug disc shaft is in sealing contact with the self-adaptive control valve, and the plug disc shaft is telescopically controlled by the telescopic control cylinder to drive the closing plug disc to move axially.

[0008] A cylindrical convex section is provided on the replacement switching pipe. A surrounding sleeve cavity is opened in the cylindrical convex section. An air blowing hole is penetrated through the inner side surface of the surrounding sleeve cavity, and the other end of the air blowing hole is communicated with the inner cavity of the replacement switching pipe.

[0009] A sealing sliding sleeve is arranged in the surrounding sleeve cavity. The sealing sliding sleeve is in sliding sealing contact with the inner side surface of the surrounding sleeve cavity. The air blowing hole is closed and blocked by the sealing sliding sleeve. An annular piston body is fixedly arranged at one end of the sealing sliding sleeve, and both the inner and outer sides of the annular piston body are in sealing contact with the inner wall surface of the surrounding sleeve cavity.

[0010] A balance spring is arranged on one side of the annular piston body. An air window is opened on the cylindrical convex section to balance the gas pressure in the surrounding sleeve cavity. An L-shaped inner groove is opened in the cylindrical convex section. One end of the L-shaped inner groove is communicated with the surrounding sleeve cavity, and the other end of the L-shaped inner groove is communicated with a shunt air pipe. When positive pressure gas is input into the L-shaped inner groove through the shunt air pipe, the gas pressure acts on the side surface of the annular piston body, pushing the sealing sliding sleeve to move axially and compressing the balance spring. At this time, a part of the air blowing holes are opened without being blocked by the sealing sliding sleeve.

[0011] A valve boss is fixedly arranged on the self-adaptive control valve. A boss cavity is arranged in the valve boss, and the boss cavity is communicated with the pressing side chamber; A piston block is arranged in the boss cavity. The piston block is in sealing sliding contact with the inner wall surface of the boss cavity. A downward pressing spring is arranged above the piston block to provide downward elastic pressure for the piston block.

[0012] A side wall air hole is provided in the valve boss. One end of the side wall air hole is communicated with a shunt air pipe, and the other end is communicated with the boss cavity. When the gas pressure in the compression side cavity is higher than a certain threshold, the air pressure pushes the piston block to rise, so that the piston block passes through the position height where the side wall air hole is located until the compression side cavity is directly communicated with the side wall air hole; A locking bolt is spirally arranged on the valve boss. The locking bolt can be adjusted up and down by rotation. When the locking bolt is at the lowest position, it can abut against the upper surface of the piston block to compress and limit the piston block to prevent the piston block from moving up.

[0013] A normally closed liquid inlet pipe with an opening and closing function is communicated with the storage unit, and liquid materials are stored in the storage unit through the normally closed liquid inlet pipe; A second check valve is arranged on the continuous delivery pipe to prevent liquid materials from entering the self-adaptive control valve through the setting of the second check valve.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The skid-mounted equipment of the present invention with storage unit transportation and supply can store and supply chemical liquid materials over a long distance. Compared with the pumping equipment in the prior art, it is more suitable for high-viscosity liquids, and when transporting liquids over a long distance, it will not be affected by the remaining amount of liquid in the storage unit.

[0015] Through the cooperation of structures such as the cylindrical convex section, the air blowing hole and the valve boss provided in the present invention, when transporting some liquids with different viscosity stratifications, the liquid viscosity during the transportation process is automatically sensed. When the liquid viscosity is too high, the above structures cooperate to automatically blow air through the air blowing hole, so that bubbles are generated in the high-viscosity liquid. The bubbles weaken the interaction between liquid molecules and reduce the frictional resistance inside the liquid, making it more convenient to push and transport over a long distance; and the number of opened air blowing holes is proportional to the liquid viscosity, realizing automatic adaptive adjustment.

[0026] [[ID=2D]]Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1 to 9 , the present invention provides a technical solution: a skid-mounted device with storage unit transportation and supply, as Figure 1As shown in the figure, it includes a skid-mounted frame 1, a storage unit 2, a compressed gas tank 3, and an adaptive control valve 4 installed in the skid-mounted frame 1. The storage unit 2 is used to store liquid materials; compressed gas is stored in the compressed gas tank 3, and the compressed gas is connected and input into the adaptive control valve 4. A pressure pipeline 5 and a continuous delivery pipe 6 are arranged on the adaptive control valve 4. The connection state between the pressure pipeline 5, the continuous delivery pipe 6 and the compressed gas tank 3 can be controlled through the adaptive control valve 4; A replacement switching pipe 7 is connected to the storage unit 2. A flange is provided at the free end of the replacement switching pipe 7. A first check valve 8 is arranged on the replacement switching pipe 7. The first check valve 8 enables the liquid material in the storage unit 2 to flow out unidirectionally through the replacement switching pipe 7; The pressure pipeline 5 is connected to the upper part of the storage unit 2. When the adaptive control valve 4 controls the connection between the compressed gas tank 3 and the pressure pipeline 5, the pressure pipeline 5 inputs compressed gas into the storage unit 2, so that the liquid material in the storage unit 2 is forced to be discharged into the replacement switching pipe 7; The continuous delivery pipe 6 is cross-connected to the side wall of the replacement switching pipe 7, and the connection port between the continuous delivery pipe 6 and the replacement switching pipe 7 is downstream of the first check valve 8, as Figure 2 shown in the figure, the above-mentioned downstream means that the liquid first passes through the first check valve 8 and then passes through the connection port between the continuous delivery pipe 6 and the replacement switching pipe 7. When the adaptive control valve 4 controls the connection between the compressed gas tank 3 and the continuous delivery pipe 6, the continuous delivery pipe 6 inputs compressed gas into the replacement switching pipe 7 to drive the liquid material in the replacement switching pipe 7 to be transported and move.

[0028] A liquid flow meter 701 is arranged on the replacement switching pipe 7 to count the liquid flowing through the replacement switching pipe 7 through the liquid flow meter 701; The arrangement position of the liquid flow meter 701 is as Figure 2 shown in the figure. The liquid flow meter 701 is located in the middle between the first check valve 8 and the connection port between the continuous delivery pipe 6 and the replacement switching pipe 7. The liquid flow meter 701 is arranged close to the connection port between the continuous delivery pipe 6 and the replacement switching pipe 7, so as to reduce the device error. A central vertical pipe 702 is vertically arranged inside the storage unit 2. A liquid inlet groove hole 703 is opened at the lower end position of the central vertical pipe 702. The upper end of the central vertical pipe 702 is connected to the replacement switching pipe 7. The liquid flow meter 701 can adopt an ultrasonic flow meter.

[0029] The self - adapting control valve 4 is provided with a pressure main chamber 401, a pressing side chamber 402 and a conveying side chamber 403. The compressed air tank 3 is communicated with the pressure main chamber 401, the pressing pipeline 5 is communicated with the pressing side chamber 402, and the continuous conveying pipe 6 is communicated with the conveying side chamber 403. Sealing and mating eaves 404, a closing plug disk 405, a plug disk shaft 406 and a telescopic control cylinder 407 are symmetrically arranged on both sides of the pressure main chamber 401. The opening and closing control between the sealing and mating eaves 404 and the closing plug disk 405 is carried out through axial movement. A plug disk shaft 406 is arranged on the closing plug disk 405, and the other end of the plug disk shaft 406 extends to the outside of the self - adapting control valve 4. The plug disk shaft 406 is in sealing contact with the self - adapting control valve 4. The plug disk shaft 406 is telescopically controlled by the telescopic control cylinder 407, so as to drive the closing plug disk 405 to move axially.

[0030] A cylindrical convex section 9 is arranged on the replacement switching pipe 7. A surrounding sleeve cavity 901 is arranged in the cylindrical convex section 9. A blowing hole 902 is penetrated through the inner surface of the surrounding sleeve cavity 901, and the other end of the blowing hole 902 is communicated with the inner cavity of the replacement switching pipe 7.

[0031] A sealing sliding sleeve 903 is arranged in the surrounding sleeve cavity 901. The sealing sliding sleeve 903 is in sliding sealing contact with the inner surface of the surrounding sleeve cavity 901. The blowing hole 902 is closed and blocked by the sealing sliding sleeve 903. An annular piston body 904 is fixedly arranged at one end of the sealing sliding sleeve 903. Both the inner and outer sides of the annular piston body 904 are in sealing contact with the inner wall surface of the surrounding sleeve cavity 901.

[0032] A balance spring 905 is arranged on one side of the annular piston body 904. An air window 906 is arranged on the cylindrical convex section 9 to balance the gas pressure in the surrounding sleeve cavity 901. An L - shaped inner groove 907 is arranged in the cylindrical convex section 9. One end of the L - shaped inner groove 907 is communicated with the surrounding sleeve cavity 901, and the other end of the L - shaped inner groove 907 is communicated with a shunt air pipe 908. When positive - pressure gas is input into the L - shaped inner groove 907 through the shunt air pipe 908, the gas pressure acts on the side surface of the annular piston body 904, pushing the sealing sliding sleeve 903 to move axially and compressing the balance spring 905. At this time, a part of the blowing holes 902 are opened without the shielding of the sealing sliding sleeve 903.

[0033] A valve boss 909 is fixedly arranged on the self - adapting control valve 4. A boss cavity 910 is arranged in the valve boss 909, and the boss cavity 910 is communicated with the pressing side chamber 402. A piston block 911 is arranged in the boss cavity 910. The piston block 911 is in sealing sliding contact with the inner wall surface of the boss cavity 910. A downward - pressing spring 912 is arranged above the piston block 911 to provide a downward elastic pressure for the piston block 911 through the downward - pressing spring 912.

[0034] The valve boss 909 is provided with a side wall air hole 913. One end of the side wall air hole 913 communicates with the shunt air pipe 908, and the other end communicates with the boss cavity 910. When the gas pressure in the compression side cavity 402 is higher than a certain threshold, the air pressure pushes the piston block 911 to rise, so that the piston block 911 passes through the position height where the side wall air hole 913 is located until the compression side cavity 402 is directly communicated with the side wall air hole 913; A locking bolt 914 is spirally arranged on the valve boss 909. The locking bolt 914 can be adjusted up and down by rotation. When the locking bolt 914 is at the lowest position, it can abut against the upper surface position of the piston block 911 to compress and limit the piston block 911 to prevent the piston block 911 from moving upward.

[0035] A normally closed liquid inlet pipe 201 with an opening and closing function is connected to the storage unit 2, and liquid materials are stored in the storage unit 2 through the normally closed liquid inlet pipe 201; A second check valve 601 is arranged on the continuous delivery pipe 6. The setting of the second check valve 601 prevents liquid materials from entering the self-adaptive control valve 4.

[0036] As Figure 1 As shown in the figure, a storage bracket 101 is fixedly arranged on the skid-mounted frame 1. The storage bracket 101 is fixedly installed with the storage unit 2, and the storage unit 2 is supported by the storage bracket 101. A platform bottom plate 102 is fixedly arranged at the bottom of the skid-mounted frame 1. A vertical back plate 103 is arranged on the skid-mounted frame 1, and the compressed air tank 3 is supported by the vertical back plate 103. The compressed air tank 3 is fixedly welded to the vertical back plate 103. Lifting lugs 104 are respectively fixedly arranged at the four corners of the upper part of the skid-mounted frame 1. The skid-mounted equipment of the present invention can be hoisted and moved by using equipment such as a crane through the lifting lugs 104. Pad feet 105 are respectively fixedly arranged at the four corners of the bottom of the skid-mounted frame 1. The support of the pad feet 105 makes a gap between the skid-mounted frame 1 and the ground, which is convenient for forklift handling.

[0037] As Figure 5 As shown in the figure, an air pump module 301 is fixedly installed on the platform bottom plate 102. Compressed gas is pumped into the compressed air tank 3 through the air pump module 301. An air delivery main pipe 302 is connected to the upper end of the compressed air tank 3, and the air delivery main pipe 302 is communicated with the pressure main cavity 401.

[0038] When the present invention is in use, the liquid materials produced by the chemical industry are added to the storage unit 2 through the normally closed liquid inlet pipe 201 for storage, and the normally closed liquid inlet pipe 201 is normally in a normally closed state. The end of the replacement switching pipe 7 is connected to an external pipeline through a flange.

[0039] When a certain amount of liquid material in the storage unit 2 needs to be transported out, first, the self - adaptive control valve 4 controls the pressure - forcing pipeline 5 to output compressed gas into the storage unit 2, so that the liquid material in the storage unit 2 enters the central vertical pipe 702 through the liquid inlet tank hole 703 and then enters the replacement switching pipe 7.

[0040] As Figure 2 shown in, when the liquid material flows through the liquid flowmeter 701, the flow is accumulated. After reaching the set flow rate, the pressure - forcing pipeline 5 is controlled to close and stop outputting compressed gas, and the continuous conveying pipe 6 is controlled to open. Compressed gas is input into the replacement switching pipe 7 through the continuous conveying pipe 6. Under the push of the compressed gas, the liquid material in the replacement switching pipe 7 continues to move along the pipeline. The continuous conveying pipe 6 continuously supplies gas, and the liquid material can be continuously pushed, realizing ultra - long - distance transportation. Until the liquid material is delivered to the target device, the continuous conveying pipe 6 is closed.

[0041] As Figure 9 shown in, the self - adaptive control valve 4 controls the axial movement of the closing plug disk 405 through the telescopic control cylinder 407 to realize the opening and closing control of the pressure - forcing pipeline 5 and the continuous conveying pipe 6.

[0042] Some chemical liquids stored in the storage unit 2 may show a layering phenomenon due to long - term static placement, resulting in the problem that the viscosities of different layers are different. If the viscosity of the liquid material in the storage unit 2 is higher than a certain threshold, when the pressure main cavity 401 is connected to the pressing side cavity 402, and the pressure - forcing pipeline 5 outputs compressed gas into the storage unit 2, during the process that the compressed gas presses the liquid material to flow out through the replacement switching pipe 7, the resistance increases, and then the pressure in the pressing side cavity 402 remains in a higher state. As Figure 9 shown in, the higher pressure acts on the lower surface of the piston block 911, causing the piston block 911 to move upward until the pressing side cavity 402 is directly connected to the side - wall air hole 913. At this time, the gas in the pressing side cavity 402 is shunted into the shunt air pipe 908.

[0043] As Figure 6 shown in, the shunt air pipe 908 inputs positive - pressure gas into the L - shaped inner groove 907. The pressure acts on one side surface of the annular piston body 904, causing the annular piston body 904 and the sealing sliding sleeve 903 to move axially, elastically compressing the balance spring 905 until reaching an equilibrium state. At this time, the air - blowing hole 902 is partially opened, so that the compressed gas is sprayed into the interior of the replacement switching pipe 7 through the air - blowing hole 902, foaming the high - viscosity liquid in the replacement switching pipe 7, weakening the interaction between liquid molecules, and reducing the frictional resistance inside the liquid.

[0044] Moreover, during the above process, the higher the viscosity of the liquid material, the greater the resistance encountered by the compressed gas output from the pressing pipeline 5 when pressing the liquid material to flow out through the replacement switching pipe 7. As a result, the gas pressure in the pressing side cavity 402 becomes higher. At this time, the greater the pressure acting on one side surface of the annular piston body 904 through the shunt gas pipe 908 and the L-shaped inner groove 907, the greater the axial movement amplitude of the annular piston body 904 and the sealing sliding sleeve 903, and finally the greater the number of opened air blowing holes 902, and the more significant the foaming treatment effect, achieving automatic adaptive adjustment.

[0045] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
