Description

Technical Field

[0001] The invention relates to the technical field of thermal insulation of storage tanks, and in particular to an automatic perlite vibrating device for a gas storage tank. Background Art

[0002] In order to maintain good thermal insulation performance, a layer of thermal insulation material, such as expanded perlite, is usually applied to the filling interlayer of the tank body. Vibration is required when filling the perlite, mainly to ensure the uniform density of the material and improve the thermal insulation effect. This process is a key step to ensure the long-term safe and efficient operation of the gas storage tank. First of all, vibration helps to remove the air in the perlite and reduce the possible settlement in the future. Through vibration, the perlite can be stacked more tightly, thereby increasing its overall density and weight, which is crucial to enhancing structural stability. During the vibration process, the perlite particles are redistributed, which promotes a more uniform distribution. The consistent density reduces the possible stratification of the material, thereby avoiding uneven insulation performance. The density of the perlite is improved after vibration, which can effectively reduce the thermal bridge effect caused by uneven materials. The perlite layer with high density has a lower thermal conductivity and improved insulation performance.

[0003] Traditional perlite vibration work mostly relies on manual work, which is labor-intensive and inefficient. Some methods of vibrating the outside of the tank have unstable vibration effects and it is difficult to ensure the uniform density of the material, which affects the insulation effect and service life of the tank. Therefore, we propose an automatic perlite vibration device for gas storage tanks to solve this problem. Summary of the invention

[0034] The beneficial effects of the present invention are:

[0035] 1. In the present invention, the automatic vibrating device for perlite in a gas storage tank is fixedly installed in the gas storage tank by a mounting seat, and then the winding motor is started to drive one of the winding wheels to rotate, and the other winding wheel is driven to rotate in the opposite direction through the meshing of two transmission gears, so as to wind up and unwind the two steel wire ropes. When winding the steel wire rope, the lifting plate can be driven to move upward, and when unwinding the steel wire rope, the lifting plate can be driven to move downward, so that the position of the vibration plate can be adjusted, so that the vibration rod is inserted into the filled perlite;

[0036] 2. In the present invention, the automatic vibrating device for perlite in a gas storage tank starts two vibration motors to drive the vibration plate to vibrate, thereby driving multiple vibration rods to vibrate synchronously, so that the vibration rods vibrate the perlite to make it more compact. During the vibration process, the connecting plate is driven to vibrate up and down through the connecting column. The setting of the connecting spring can make the vibration plate vibrate smoothly without affecting the stability of the lifting plate;

[0037] 3. In the present invention, the automatic perlite vibrating device for a gas storage tank can vibrate synchronously with the vibration plate by fixing the installation box on the vibration plate, and the counterweight plate is positioned in the front and rear positions and the up and down positions by the transverse spring and the vertical spring, so that the counterweight plate has the degree of freedom in the front and rear directions and the up and down directions relative to the installation box. During the vibration of the installation box, the counterweight plate can cause a lag between its movement and the installation box under its own inertia, that is, when the installation box is vibrating forward and backward and left and right, the counterweight plate will not quickly maintain the synchronous movement with the installation box. Instead of moving, it first remains motionless under its own inertia, thereby compressing or stretching the transverse spring and the vertical spring, and then moves accordingly under the elastic force of the transverse spring and the vertical spring. In this process, the forward and backward movement component of the counterweight plate will drive the first conductive sheet to move forward and backward synchronously through the T-plate, the guide rod and the sliding seat, and the up and down movement of the counterweight plate will drive the third conductive sheet to move continuously through the T-plate, the circular frame and the transverse plate. When the forward and backward vibration amplitude of the installation box is large enough, the first conductive sheet will be out of contact with the second conductive sheet, and the upper and lower conductive sheets of the installation box will be moved. When the vibration amplitude is large enough, the third conductive sheet will be separated from the fourth conductive sheet. When any of the above situations occurs, the signal light will be powered off, causing the signal light to flicker during the vibration process. As the vibration process proceeds, the density of the perlite gradually increases, causing the resistance of the vibrating rod to the perlite to increase. The increase in resistance will reduce the vibration amplitude of the vibration plate, the vibrating rod and the installation box. When the front and rear vibration amplitudes and the up and down movement amplitudes of the installation box are small enough, the first conductive sheet will not be able to maintain contact with the second conductive sheet, and the third conductive sheet will maintain contact with the fourth conductive sheet, so that the signal light remains powered on. After the signal light remains on for a period of time, the signal is transmitted to the main controller. The main controller controls the dual-axis motor to start and drive the two active sprockets to rotate, and drives the four driven sprockets to rotate through the corresponding chains, thereby driving the four support wheels to rotate through the corresponding support shafts, and the rolling of the support wheels in the annular track drives the moving seat to perform circular motion along the trajectory of the annular track, thereby driving the vibrating rod to move around the inner wall of the gas storage tank, thereby achieving vibration work at different positions.

[0038] 4. In the present invention, the automatic vibrating device for perlite in a gas storage tank can realize automatic sampling and density detection of the vibrated perlite through the provided sampling and detection mechanism, and adjust the vibration strategy according to the detected compacted density, thereby ensuring the vibration effect;

[0039] 5. In the present invention, the automatic perlite vibrating device for a gas storage tank can conveniently realize the lifting and lowering movement control and horizontal movement control of the vibrating rod through the cooperation of the dual-axis motor and the winding motor, thereby enabling automated vibration work.

The same chain 205 is installed on the driving sprocket 204 and the driven sprocket 203 on the same side of the circular track 1. A plurality of mounting seats 101 are fixedly connected to the top of the circular track 1, and a plurality of assembly holes are provided on the top of the mounting seats 101 to facilitate fixing the circular track 1 in the gas storage tank; a main controller 13 is fixedly installed on the bottom of the movable seat 2, and the main controller 13 is connected to the dual-axis motor 206, the winding motor 304, the vibration motor 402, the drive motor 1103 and the rotating motor 902 by signal, so that the overall automatic control can be performed through the main controller 13.

[0079] In this embodiment, when in use, the annular track 1 is fixedly installed in the gas storage tank through the mounting seat 101, and then the winding motor 304 is started to drive one of the winding wheels 302 to rotate, and the other winding wheel 302 is driven to rotate in the opposite direction through the engagement of the two transmission gears 303, so as to reel in and unreel the two steel wire ropes 301. When the steel wire rope 301 is wound up, the lifting plate 3 can be driven to move upward, and when the steel wire rope 301 is unwound, the lifting plate 3 can be driven to move downward, so that the position of the vibration plate 4 is adjusted, so that the vibration rod 401 is inserted into the filled perlite;

[0080] By starting the two vibration motors 402, the vibration plate 4 is driven to vibrate, thereby driving the multiple vibration rods 401 to vibrate synchronously, so that the vibration rods 401 vibrate the perlite to make it more compact. During the vibration process, the connecting column 40306 drives the connecting plate to vibrate up and down. The setting of the connecting spring 40303 can make the vibration plate 4 vibrate smoothly without affecting the stability of the lifting plate 3.

[0081] By fixing the installation box 5 on the vibration plate 4, it can vibrate synchronously with the vibration plate 4. Since the counterweight plate 503 is positioned in the front-to-back position and the up-and-down position by the transverse spring 508 and the vertical spring 506, the counterweight plate 503 has freedom in the front-to-back direction and the up-and-down direction relative to the installation box 5. During the vibration of the installation box 5, the counterweight plate 503 can cause a lag between its movement and the installation box 5 due to its own inertia. That is, when the installation box 5 vibrates front-to-back and left-to-right, the counterweight plate 503 will not quickly maintain synchronous movement with the installation box 5, but will first remain motionless under its own inertia, thereby compressing or stretching the transverse spring 508 and the vertical spring 506, and then move accordingly under the elastic force of the transverse spring 508 and the vertical spring 506. In this process, the front-to-back movement component of the counterweight plate 503 will drive the first conductive sheet 511 to move forward and backward synchronously through the T-plate 505, the guide rod and the sliding seat 507, and the up-and-down movement of the counterweight plate 503 will be The mold plate 505, the circular frame 504 and the horizontal plate 509 drive the third conductive sheet 513 to move continuously. When the front-to-back vibration amplitude of the installation box 5 is large enough, the first conductive sheet 511 and the second conductive sheet 512 will be disengaged, and when the up-and-down vibration amplitude of the installation box 5 is large enough, the third conductive sheet 513 and the fourth conductive sheet 514 will be disengaged. When any of the above situations occurs, the signal light 502 will be powered off, so that the signal light 502 will appear to be flickering during the vibration process. As the vibration process proceeds, the density of the perlite gradually increases, so that the resistance of the vibrating rod 401 to the perlite increases. The increase in resistance will reduce the vibration amplitude of the vibration plate 4, the vibrating rod 401 and the installation box 5. When the front-to-back vibration amplitude and the up-and-down movement amplitude of the installation box 5 are small enough, the first conductive sheet 511 will not be able to maintain contact with the second conductive sheet 512, and the third conductive sheet 513 will maintain contact with the fourth conductive sheet 514, so that the signal light 502 remains powered on and lit.

[0082] After the signal light 502 remains on for a period of time, it transmits the signal to the main controller 13. The main controller 13 controls the dual-axis motor 206 to start and drive the two active sprockets 204 to rotate, and drives the four driven sprockets 203 to rotate through the corresponding chains 205, thereby driving the four support wheels 202 to rotate through the corresponding support shafts, and the rolling of the support wheels 202 in the annular track 1 drives the moving seat 2 to perform a circular motion along the track of the annular track 1, thereby driving the vibrating rod 401 to move around the inner wall of the gas storage tank, thereby realizing the vibration work at different positions;

[0083] By reading the pressure value monitored by the second pressure sensor 1202 and recording it as F' (N), the cylinder 1001 is started to drive the U-shaped frame 10 to move downward, thereby driving the sampling tube 7 to move downward, so that the sampling tube 7 is inserted into the vibrated perlite. When the first pressure sensor 1201 senses sufficient pressure, it means that the lower surface of the sampling tube 7 is completely inserted into the perlite. Then, the main controller 13 starts the electric push rod 801 and controls its output end to contract, thereby driving the piston plate 8 to move upward, and the upward movement distance is recorded as H (m). In this process, the cylinder 1001 continues to control the sampling tube 7 to move downward so that it continues to extend into the perlite. Then, after the piston plate 8 moves to the outside, the cylinder 1001 is started to drive the U-shaped frame 10 and the sampling tube 7 to move upward. After the sampling tube 7 is out of the perlite, the drive motor is started. 1103 drives the driving gear 1102 to rotate, and the driving gear 1102 drives the rotating shaft 11 to rotate by meshing with the driven gear 1101. The rotating shaft 11 drives the sampling tube 7 to rotate 180° through the square plate 12, the guide column 1204 and the flat plate 1203, and continues to control the sampling tube 7 to move up until it contacts the scraper 9, and then starts the electric push rod 801 to drive the piston plate 8 to move up a distance of one end, recorded as h (m), and pushes out a part of the sampled perlite in the sampling tube 7, and starts the rotating motor 902 to drive the scraper 9 to rotate back and forth, and scrapes the perlite on the top of the sampling tube 7 flat, and then controls the scraper 9 to rotate away, so that it is out of contact with the sampling tube 7, and reads the pressure value of the first pressure sensor 1201, recorded as F (N), and then calculates the tap density of the perlite according to the following formula through the main controller 13:

[0084] P = (Fg-F'g) / (S*HS*h) (1)

[0085] (1) Where:

[0086] Ρ---Pearlite tap density, unit is kg / m3;

[0087] g---gravity constant, unit is N / Kg;

[0088] S---the bottom area of ​​the piston plate 8, in m2;

[0089] H---The first moving distance of the piston plate 8, in m;

[0090] h---the second moving distance of the piston plate 8, in m;

[0091] F'---the pressure value monitored by the second pressure sensor 1202 in the initial state, in N;

[0092] F---pressure value monitored by the first pressure sensor 1201, in N;

[0093] After the detection is completed, the electric push rod 801 can be started to drive the piston plate 8 to move upward, and the sampled perlite can be completely pushed out of the sampling tube 7, and the rotary motor 902 can be started to drive the scraper 9 to rotate back and forth to scrape the surface of the piston plate 8 to restore it to a clean state to avoid affecting the next detection;

[0094] The main controller 13 analyzes the compacted density of the perlite. When the density does not reach the standard, the vibration intensity and time of the vibration motor 402 are adjusted to ensure the compaction effect of the perlite.
