Description

Technical Field

[0001] The invention belongs to the technical field of structural design of carbon dioxide stabilization buffer tanks, and in particular relates to a high-stability carbon dioxide buffer tank. Background Art

[0002] The main function of the CO2 stabilization buffer tank is to stabilize the supply of CO2, reduce pressure fluctuations, and thus improve production efficiency. Its working principle is to stabilize the pressure of CO2 through the internal buffer volume. When the CO2 supply pressure changes, the buffer tank can respond quickly and ensure the output CO2 pressure is stable by adjusting the internal pressure.

[0003] The current carbon dioxide buffer tank mainly has the following technical problems: a. The airbag, as the core component of the buffer tank, will gradually age after long-term use, resulting in a decrease in its elasticity and sealing performance, which is likely to affect its buffering effect; b. Since the airbag is installed on the connecting pipe of the buffer tank, when disassembling, the pressure plate that contacts the end of the airbag must be removed from the tank connecting pipe. The pressure plate is mostly installed on the connecting pipe by fixing bolts. When the fixing bolts are loose, it is easy to affect the sealing between the airbag and the tank body, which is not conducive to improving the use effect of the buffer tank; c. If the catheter installed on the water inlet pipe is not sealed well, it is easy to cause water seepage, making it impossible for water to be discharged into the tank normally.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0029] See also Figures 1 to 10 As shown, an embodiment of the present invention provides a high-stability carbon dioxide buffer tank, including a buffer tank body 1, an adjusting mechanism 2 and a fixing mechanism 5 are fixedly installed on the buffer tank body 1, an airbag 6 is clamped and installed in the fixing mechanism 5, a plurality of supporting mechanisms 7 are fixedly installed in the buffer tank body 1 in an annular shape and equidistantly, a water inlet pipe 4 is fixedly installed on the fixing mechanism 5, the water inlet pipe 4 is connected with the inside of the airbag 6 through the fixing mechanism 5, and a mounting mechanism 3 is fixed on the water inlet pipe 4. Specifically in this embodiment, starting the adjusting mechanism 2 can drive the buffer tank body 1 to move upward, so that the fixing mechanism 2 can be farther away from the ground, so as to facilitate the replacement of the airbag 6 installed in the buffer tank body 1. By rotating the fixing mechanism 5 with a tool, it can be disassembled, so that it is convenient to extract the airbag 6 from the bottom end of the buffer tank body 1, and at the same time, the sealing effect between the airbag 6 and the fixing mechanism 5 can be improved during installation. Fixing the mounting mechanism 3 at the end of the water inlet pipe 4 can prevent the mounting mechanism 3 from falling off the water inlet pipe 4 during use.

[0030] See also Figures 1 to 10As shown, the fixing mechanism 5 specifically includes a connecting pipe 502 and a fixing plate 504. The bottom end of the buffer tank body 1 is fixedly connected with the connecting pipe 502, and the airbag 6 is clamped and installed in the connecting pipe 502. A plurality of fixing plates 504 are fixedly connected to the connecting pipe 502 in an annular shape and equidistantly. A stopper 505 is rotatably connected to the fixing plate 504, and a sealing pipe 503 is sleeved on the end of the airbag 6. A cover plate 501 is fixedly installed on the sealing pipe 503, and a plurality of limiting holes 507 are equidistantly provided in an annular shape on the cover plate 501. The stopper 505 is rotatably connected to the cover plate 501, and a limiting rod 506 runs through the stopper 505, and the limiting rod 506 is threadedly connected to the cover plate 501. The water inlet pipe 4 is fixedly installed on the cover plate 501, and the water inlet pipe 4 is connected to the inside of the airbag 6 through the cover plate 501. The limiting rod 506 is threadedly connected to the stopper 505, and the airbag 6 is located inside the buffer tank body 1. The fixing mechanism 5 can be disassembled by rotating it with a tool, which makes it easier to extract the airbag 6 from the bottom end of the buffer tank body 1 and also improves the sealing effect between the airbag 6 and the fixing mechanism 5 during installation.

[0031] Specifically in this embodiment, when removing the airbag 6, the operator can use a tool to rotate the limit rod 506, which is threadedly installed inside the cover plate 501. When it is rotated from the inside of the cover plate 501 to the inside of the stop block 505, the limit rod 506 can be separated from the cover plate 501. At this time, the stop block 505 is rotated again, and the stop block 505 is rotated along the fixing plate 504 to a direction away from the cover plate 501, so that the cover plate 501 loses the limit of the stop block 505, and the sealing tube 503 fixed on the cover plate 501 is released. By removing it from the end of the airbag 6, the end of the airbag 6 can be put in a stuck state, and then the airbag 6 can be pulled out from the buffer tank body 1 using a tool to replace the airbag 6. After the new airbag 6 is removed and placed in the buffer tank body 1, the sealing tube 503 is stuck into the end of the airbag 6 to increase the sealing effect between the airbag 6 and the cover plate 501 and the connecting tube 502; then rotate the stop block 505, and re-thread the limit rod 506 into the cover plate 501 to quickly fix the cover plate 501.

[0032] See also Figures 1 to 10As shown, the support mechanism 7 specifically includes a support plate 701 and a connection block 702. A plurality of connection blocks 702 are fixedly installed on the buffer tank body 1 in an annular shape and are equidistant. A support plate 701 is fixedly installed on the connection block 702. The plurality of support plates 701 are arranged in an annular shape and are equidistant, and the support plate 701 is arranged in an arc surface structure. The adjustment mechanism 2 includes a support rod 202 and a fixed rod 203. A plurality of fixed rods 203 are fixedly installed on the bottom end of the buffer tank body 1. The bottom end of the fixed rod 203 is installed with the support rod 202. The support rod 202 is fixedly connected to the base 201. A hydraulic rod 204 is fixedly installed inside the support rod 202. The telescopic end of the hydraulic rod 204 is fixedly connected to the fixed rod 203. A plurality of fixed rods 203 are arranged in an annular shape and are equidistant at the bottom end of the buffer tank body 1. The fixing rod 203 is slidably connected to the supporting rod 202 , and the adjusting mechanism 2 is started to drive the buffer tank body 1 to move upward, so that the fixing mechanism 5 is farther away from the ground, thereby facilitating the replacement of the airbag 6 installed in the buffer tank body 1 .

[0033] Specifically in the present embodiment, after the buffer tank body 1 has been used for a long period of time, the airbag 6 installed in the buffer tank body 1 needs to be replaced. Before replacing the airbag 6, the operator can first start the control switch of the hydraulic rod 204. The hydraulic rod 204 is fixed inside the support rod 202. The telescopic end of the hydraulic rod 204 is fixedly connected with the fixed rod 203. Two groups of support rods 202 are fixedly installed on the top of the base 201. When the hydraulic rod 204 is started, its telescopic end can drive the fixed rod 203 to slide, and the fixed rod 203 moves up along the inner wall of the support rod 202. Since several fixed rods 203 are fixed in a ring shape and equidistantly at the bottom end of the buffer tank body 1, the displacement of the fixed rod 203 can drive the buffer tank body 1 to move, thereby increasing the distance between the connecting pipe 502 installed at its end and the ground, thereby increasing the operating space for the operator when removing the airbag 6, which is beneficial to improving the work efficiency of replacing the airbag 6.

[0034] See also Figure 7 and Fig.10As shown, the installation mechanism 3 specifically includes a sleeve 302 and a fixing block 303. The end of the water inlet pipe 4 is fixedly connected with the fixing block 303. A clamping groove 307 is provided in the fixing block 303. A sealing gasket 306 is bonded to the clamping groove 307. A plug 305 is clamped and connected in the water inlet pipe 4. The plug 305 is fixedly connected with a clamping block 304. A guide tube 301 is fixedly installed on the clamping block 304. The sleeve 302 is sleeved on the guide tube 301. The sleeve 302 and the fixing block 303 are threadedly connected. The guide tube 301 is connected to the inside of the water inlet pipe 4 through the plug 305. The diameter of the plug 305 is equal to the inner diameter of the water inlet pipe 4. The sleeve 302 and the guide tube 301 are rotatably connected. A block 304 is mounted in the slot 307 , the block 304 contacts the sealing gasket 306 , and the sleeve 302 contacts the side wall of the block 304 , fixing the installation mechanism 3 at the end of the water inlet pipe 4 , which can prevent the installation mechanism 3 from falling off the water inlet pipe 4 during use.

[0035] Specifically, in the present embodiment, before using the buffer tank body 1, the conduit 301 needs to be installed. A clamping block 304 is fixed at the end of the conduit 301, and a plug 305 is installed on the clamping block 304. After the plug 305 is clamped to the end of the water inlet pipe 4, the clamping block 304 can be clamped to the clamping groove 307 provided in the fixing block 303. A sealing gasket 306 is bonded to the clamping groove 307. The clamping block 304 contacts the sealing gasket 306, which can improve the sealing effect between the plug 305 and the water inlet pipe 4. The sleeve 302 sleeved on the rotating conduit 301 can be threadedly installed on the side wall of the fixing block 303. When the sleeve 302 conflicts with the end of the clamping block 304, the conduit can be 301 is connected with the inside of the water inlet pipe 4 through the block 304 and the insert tube 305, so that the water inlet pipe 4 can inject liquid into the airbag 6 when the buffer tank body 1 is in use; when the buffer tank body 1 is in use, when the system water pressure is greater than the air pressure between the carbon steel tank body of the buffer tank and the airbag 6, the system water will be squeezed into the airbag 6 under the action of the system pressure, compressing the gas between the tank body and the airbag 6, reducing its volume and increasing its pressure; when the system water pressure is less than the gas pressure in the tank, the water in the airbag 6 will be squeezed out under the pressure of the nitrogen between the buffer tank body 1 and the airbag 6, and replenished back to the system until the system water pressure and the air pressure between the buffer tank body 1 and the airbag 6 reach a new balance.

[0036] When the present invention is in use, first, after the buffer tank body 1 has been used for a long time, the airbag 6 installed in the buffer tank body 1 needs to be replaced. Before replacing the airbag 6, the operator can first start the control switch of the hydraulic rod 204. The hydraulic rod 204 is fixed inside the support rod 202. The telescopic end of the hydraulic rod 204 is fixedly connected with the fixing rod 203. The two groups of support rods 202 are fixedly installed on the top of the base 201. When the hydraulic rod 204 is started, its telescopic end can drive the fixing rod 203 to slide, and the fixing rod 203 moves up along the inner wall of the support rod 202. Since a plurality of fixing rods 203 are fixed at an equal distance in a ring shape at the bottom end of the buffer tank body 1, the displacement of the fixing rod 203 can drive the buffer tank body 1 to move, thereby making the distance between the connecting pipe 502 installed at its end and the ground farther, thereby increasing the operating space for the operator to disassemble the airbag 6, which is conducive to improving the working efficiency of replacing the airbag 6.

[0037] When removing the airbag 6, the operator can use a tool to rotate the limit rod 506, which is threadedly installed inside the cover plate 501. When it is rotated from the inside of the cover plate 501 to the inside of the stop block 505, the limit rod 506 can be separated from the cover plate 501. At this time, the stop block 505 is rotated again, and the stop block 505 is rotated along the fixing plate 504 to the direction away from the cover plate 501, so that the cover plate 501 loses the limit of the stop block 505, and the sealing tube 503 fixed on the cover plate 501 is removed from the end of the airbag 6. The end of the airbag 6 can be put in a stuck state by disassembling the airbag 6 from the buffer tank body 1, and then the airbag 6 can be pulled out from the buffer tank body 1 by using a tool to replace the airbag 6. After the new airbag 6 is disassembled and placed in the buffer tank body 1, the sealing tube 503 is stuck into the end of the airbag 6 to increase the sealing effect between the airbag 6 and the cover plate 501 and the connecting tube 502; then the stop block 505 is rotated to re-thread the limit rod 506 into the cover plate 501, so that the cover plate 501 can be quickly fixed;

[0038] Before using the buffer tank body 1, the catheter 301 needs to be installed. A clamping block 304 is fixed at the end of the catheter 301, and a plug 305 is installed on the clamping block 304. After the plug 305 is clamped to the end of the water inlet pipe 4, the clamping block 304 can be clamped to the clamping groove 307 provided in the fixing block 303. A sealing gasket 306 is bonded to the clamping groove 307. The contact between the clamping block 304 and the sealing gasket 306 can improve the sealing effect between the plug 305 and the water inlet pipe 4. The sleeve 302 sleeved on the rotating catheter 301 can be threadedly installed on the side wall of the fixing block 303. When the sleeve 302 conflicts with the end of the clamping block 304, the catheter 301 can be passed. The block 304 and the insert tube 305 are connected with the interior of the water inlet pipe 4, so that the water inlet pipe 4 can be used to inject liquid into the airbag 6 when the buffer tank body 1 is in use; when the buffer tank body 1 is used, when the system water pressure is greater than the air pressure between the carbon steel tank body of the buffer tank and the airbag 6, the system water will be squeezed into the airbag 6 under the action of the system pressure, compressing the gas between the tank body and the airbag 6, reducing its volume and increasing its pressure; when the system water pressure is lower than the gas pressure in the tank, the water in the airbag 6 will be squeezed out under the pressure of the nitrogen between the buffer tank body 1 and the airbag 6, and replenished back to the system until the system water pressure and the air pressure between the buffer tank body 1 and the airbag 6 reach a new balance.
