Description

Technical Field

[0001] The present invention relates to the technical field of storage tank heat insulation, and particularly to a perlite automatic vibrating device for a gas storage tank. Background Technique

[0002] In order to maintain good heat insulation performance, a layer of heat insulation material, such as expanded perlite, is usually applied in the filling interlayer of the tank body of a gas storage tank. When filling perlite, vibration is required, mainly to ensure the uniform density of the material and improve the heat 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 expel the air in the perlite, reducing the possible settlement phenomenon in the future. Through vibration, the perlite can be piled up more tightly, thereby increasing its overall density and weight, which is crucial for enhancing the structural stability. During the vibration process, the perlite particles are redistributed, promoting a more uniform distribution. The consistent density reduces the possible delamination phenomenon of the material, thus avoiding the non-uniformity of the insulation performance. After vibration, the density of the perlite increases, which can effectively reduce the thermal bridge effect caused by material non-uniformity. The perlite layer with a high density has a lower thermal conductivity, improving the insulation performance.

[0003] The traditional perlite vibration work mostly relies on manual operation, with a large labor intensity and low efficiency. Moreover, some vibration methods carried out outside the storage tank have unstable vibration effects and are difficult to ensure the uniform density of the material, affecting the insulation effect and service life of the storage tank; therefore, we propose a perlite automatic vibrating device for a gas storage tank to solve this problem.

[0032] Preferably, a plurality of mounting seats are fixedly connected to the top of the annular track, and a plurality of assembly holes are opened in the top of the mounting seat;

[0033] A main controller is fixedly installed at the bottom of the moving seat, and the main controller is in signal connection with the dual-axis motor, the winding motor, the vibration motor, the driving motor and the rotating motor.

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

[0035] 1. In the present invention, for the automatic vibrating device for perlite in a gas storage tank, the annular track is fixedly installed in the gas storage tank through the 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 reverse direction through the meshing of the two transmission gears, so as to wind and unwind the two steel wire ropes. When the steel wire rope is wound, the lifting plate can be driven to move upward, and when the steel wire rope is unwound, the lifting plate can be driven to move downward, so as to adjust the position of the vibrating plate and make the vibrating rod insert into the filled perlite;

[0036] 2. In the present invention, for the automatic vibrating device for perlite in a gas storage tank, by starting the two vibration motors, the vibrating plate is driven to vibrate, so as to drive a plurality of vibrating rods to vibrate synchronously, and the vibrating rods vibrate the perlite to make it more compact. During the vibration process, the connecting column drives the connecting plate to vibrate up and down, and the setting of the connecting spring can enable the vibrating plate to vibrate smoothly and does not affect the stability of the lifting plate;

[0037] 3. In the present invention, for the automatic vibrating device for perlite in a gas storage tank, by fixing the installation box on the vibrating plate, it can vibrate synchronously with the vibrating plate. Since the counterweight plate is positioned in the front-back and up-down positions through the horizontal spring and the vertical spring, the counterweight plate has degrees of freedom in the front-back and up-down directions relative to the installation box. During the vibration of the installation box, the counterweight plate can lag behind the installation box due to its own inertia. That is, when the installation box vibrates back and forth and left and right, the counterweight plate will not quickly move synchronously with the installation box. Instead, it first remains stationary under its own inertia, thereby compressing or stretching the horizontal spring and the vertical spring. Then, it moves correspondingly under the elastic force of the horizontal spring and the vertical spring. During this process, the front-back movement component of the counterweight plate will drive the first conductive sheet to move synchronously back and forth through the T-shaped plate, the guide rod, and the sliding seat. The up-down movement of the counterweight plate will drive the third conductive sheet to move continuously through the T-shaped plate, the return frame, and the cross plate. When the back-and-forth vibration amplitude of the installation box is large enough, the first conductive sheet will be separated from the second conductive sheet. When the up-down vibration amplitude of the installation box is large enough, the third conductive sheet will be separated from the fourth conductive sheet. When any of the above situations occurs, the signal lamp will be powered off, causing the signal lamp to flicker during the vibration process. As the vibrating process progresses, the compactness of the perlite gradually increases, causing the resistance to the vibrating rod from the perlite to increase. The increase in resistance will cause the vibration amplitudes of the vibrating plate, the vibrating rod, and the installation box to decrease. When the back-and-forth vibration amplitude and the up-down movement amplitude of the installation box are both 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, thereby causing the signal lamp to remain powered on and lit. After the signal lamp remains constantly lit for a period of time, it transmits a signal to the main controller. The main controller controls the dual-axis motor to start and drive the two driving sprockets to rotate, and drives the four driven sprockets to rotate through the corresponding chains. Then, it drives the four supporting wheels to rotate through the corresponding support shafts. By the rolling of the supporting wheels in the annular track, the moving seat is driven to move in a 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, so as to achieve vibrating work at different positions;

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

[0039] 5. In the present invention, for the automatic vibrating device for perlite in a gas storage tank, through the cooperation of the provided dual-axis motor and the winding motor, it can conveniently realize the control of the lifting and horizontal movement of the vibrating rod, so as to be able to perform automatic vibrating work.

The output shaft of the winding motor 304 is fixedly connected to the front end of one of the winding wheels 302, so as to drive the winding wheel 302 to rotate. The rear ends of the two winding wheels 302 are fixedly connected to the same transmission gear 303. The two transmission gears 303 are meshed with each other to ensure the reverse rotation of the two winding wheels 302. Installation frames 305 are fixedly installed on both sides of the top of the lifting plate 3. A fixed pulley 306 is rotatably installed in the installation frame 305.

[0078] In this embodiment, a double-shaft motor 206 is fixedly installed on the top of the moving seat 2. Active sprockets 204 are fixedly connected to the two output shafts of the double-shaft motor 206. A support shaft is fixedly connected to one side of the support wheel 202. Vertical plates 201 are fixedly connected to both sides of the top of the moving seat 2. The support shaft is rotatably connected in the corresponding vertical plate 201, and the other end of the support shaft is fixedly connected to a driven sprocket 203. The same chain 205 is installed on the active sprocket 204 and the driven sprocket 203 on the same side of the annular track 1. A plurality of mounting seats 101 are fixedly connected to the top of the annular track 1. A plurality of assembly holes are formed in the top of the mounting seat 101 to facilitate the fixation of the annular track 1 in the gas storage tank. A main controller 13 is fixedly installed on the bottom of the moving seat 2. The main controller 13 is in signal connection with the double-shaft motor 206, the winding motor 304, the vibrating motor 402, the driving motor 1103, and the rotating motor 902, so as to realize the overall automatic control through the main controller 13.

[0079] In this embodiment, during use, the annular track 1 is fixedly installed in the gas storage tank through the mounting base 101. 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 wind and unwind the two wire ropes 301. When the wire rope 301 is wound, the lifting plate 3 can be driven to move upward, and when the wire rope 301 is unwound, the lifting plate 3 can be driven to move downward, so as to adjust the position of the vibrating plate 4, and make the vibrating rod 401 insert into the filled perlite;

[0080] By starting the two vibration motors 402, the vibrating plate 4 is driven to vibrate, so as to drive a plurality of vibrating rods 401 to vibrate synchronously, so that the vibrating rods 401 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 40306. The setting of the connecting spring 40303 can enable the vibrating plate 4 to vibrate smoothly and will not affect 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-back and up-down positions through the lateral spring 508 and the vertical spring 506, the counterweight plate 503 has degrees of freedom in the front-back direction and the up-down direction relative to the installation box 5. During the vibration of the installation box 5, the counterweight plate 503 can lag behind the installation box 5 under its own inertia. That is, when the installation box 5 vibrates back and forth and left and right, the counterweight plate 503 will not quickly move synchronously with the installation box 5. Instead, it will first remain stationary under its own inertia, thereby compressing or stretching the lateral spring 508 and the vertical spring 506. Then, it will move correspondingly under the elastic force of the lateral spring 508 and the vertical spring 506. During this process, the front-back movement component of the counterweight plate 503 will drive the first conductive sheet 511 to move synchronously back and forth through the T-shaped plate 505, the guide rod, and the sliding seat 507. The up-down movement of the counterweight plate 503 will drive the third conductive sheet 513 to move continuously through the T-shaped plate 505, the loop frame 504, and the cross plate 509. When the front-back vibration amplitude of the installation box 5 is large enough, the first conductive sheet 511 will be separated from the second conductive sheet 512. When the up-down vibration amplitude of the installation box 5 is large enough, the third conductive sheet 513 will be separated from the fourth conductive sheet 514. When any of the above situations occurs, the signal lamp 502 will be powered off, causing the signal lamp 502 to flicker during the vibration process. As the vibration compaction process progresses, the compactness of the perlite gradually increases, causing the resistance of the vibration rod 401 to the perlite to increase. The increase in resistance will cause the vibration amplitudes of the vibration plate 4, the vibration rod 401, and the installation box 5 to decrease. When the front-back vibration amplitude and the up-down movement amplitude of the installation box 5 are both small enough, the first conductive sheet 511 will not be able to remain in contact with the second conductive sheet 512, and the third conductive sheet 513 will remain in contact with the fourth conductive sheet 514, thereby keeping the signal lamp 502 in the powered-on and lit state;

[0082] After the signal lamp 502 remains constantly lit for a period of time, it transmits a signal to the main controller 13. The main controller 13 controls the double-axis motor 206 to start and drive the two driving sprockets 204 to rotate, and drives the four driven sprockets 203 to rotate through the corresponding chains 205. Thereby, it drives the four supporting wheels 202 to rotate through the corresponding supporting shafts. The rolling of the supporting wheels 202 in the annular track 1 drives the moving seat 2 to move in a circular motion along the trajectory of the annular track 1, thereby driving the vibration rod 401 to move around the inner wall of the gas storage tank, so as to realize the vibration compaction work at different positions;

[0083] By reading the pressure value monitored by the second pressure sensor 1202 and denoted as F' (N), the cylinder 1001 is activated to drive the U-shaped frame 10 to move downward, thereby driving the sampling cylinder 7 to move downward, so that the sampling cylinder 7 is inserted into the vibrated perlite. When the first pressure sensor 1201 senses sufficient pressure, it indicates that the lower surface of the sampling cylinder 7 is completely inserted into the perlite. Then, the main controller 13 activates the electric push rod 801 and controls the contraction of its output end, thereby driving the piston plate 8 to move upward, and the upward movement distance is denoted as H (m). During this process, the sampling cylinder 7 is continuously controlled to move downward by the cylinder 1001 so that it continues to extend into the perlite. Then, after the piston plate 8 moves outside, the cylinder 1001 is activated to drive the U-shaped frame 10 and the sampling cylinder 7 to move upward. After the sampling cylinder 7 is removed from the perlite, the drive motor 1103 is activated to drive the driving gear 1102 to rotate. The driving gear 1102 drives the rotating shaft 11 to rotate through the engagement with the driven gear 1101. The rotating shaft 11 drives the sampling cylinder 7 to rotate 180° through the square plate 12, the guide post 1204 and the flat plate 1203, and continues to control the sampling cylinder 7 to move upward until it contacts the scraper 9. Then, the electric push rod 801 is activated to drive the piston plate 8 to move upward a certain distance, denoted as h (m), to push out a part of the sampled perlite in the sampling cylinder 7, and the rotating motor 902 is activated to drive the scraper 9 to rotate reciprocally to level the perlite at the top of the sampling cylinder 7. Then, the scraper 9 is controlled to rotate away and separated from the sampling cylinder 7, and the pressure value of the first pressure sensor 1201 is read and denoted as F (N). Then, the main controller 13 calculates the tapped density of the perlite according to the following formula:

[0084] Ρ = (F - F') / g(S * H - S * h) (1)

[0085] In formula (1):

[0086] Ρ --- Tapped density of perlite, unit: kg / m3;

[0087] g --- Gravitational constant, unit: N / Kg;

[0088] S --- Bottom area of the piston plate 8, unit: m2;

[0089] H --- First movement distance of the piston plate 8, unit: m;

[0090] h --- Second movement distance of the piston plate 8, unit: m;

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

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

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

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