Description

Technical Field

[0001] This utility model relates to the field of flue gas sampling cylinder repair technology, specifically a stainless steel sleeve for repairing flue gas sampling cylinders. Background Technology

[0002] A flue gas sampling tube is a pipe used to collect flue gas. Its main purpose is to provide a method for collecting flue gas from multiple points, making the sampling more representative and thus ensuring the authenticity and reliability of the test data. Flue gas sampling tubes play an important role in environmental monitoring, industrial safety and health assessment. By collecting and analyzing the components in flue gas, the composition, concentration and size distribution of gases and particulate matter can be determined.

[0003] Most existing flue gas sampling cylinders are located outside the factory. Under long-term exposure to wind and rain and flue gas corrosion, the flue gas sampling cylinders will be damaged. The current method is to remove and replace the entire flue gas sampling cylinder, which is not only time-consuming and labor-intensive but also wasteful of resources. Some manufacturers use sheet metal to fill and weld the damaged parts of the flue gas sampling cylinder, but the process of welding sheet metal is also quite cumbersome. Utility Model Content

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution as follows: Figures 1 to 4 As shown, in this embodiment, a stainless steel sleeve for repairing a flue gas sampling cylinder includes a flue gas sampling cylinder 1. A collar 2 is fitted around the outer side of the flue gas sampling cylinder 1. There are two sets of collars 2, each including a first semicircular ring 21 and a second semicircular ring 22. The first semicircular ring 21 and the second semicircular ring 22 surround the flue gas sampling cylinder 1, with the two collars 2 arranged one above the other. The first semicircular ring 21 and the second semicircular ring 22 are fitted together. An installation groove 3 is provided on the inner ring of each collar 2. A repair ring 4 is provided between the two collars 2. The repair ring 4 is located inside the repair ring 4 between the two collars 2. The repair ring 4 is made of stainless steel. A suitable repair ring 4 is cut to size... The repair ring 4 is placed between the mounting grooves 3 on the two sets of rings 2. Then, the first semicircular ring 21 and the second semicircular ring 22 are placed on the outside of the flue gas sampling cylinder 1. The first semicircular ring 21 and the second semicircular ring 22 are installed between each other to stably fix the rings 2 on the flue gas sampling cylinder 1. By corresponding the repair ring 4 to the damaged position of the flue gas sampling cylinder 1, the damaged position of the flue gas sampling cylinder 1 can be repaired. Using the repair ring 4 of a specified size to repair the damaged position of the flue gas sampling cylinder 1 greatly reduces the cost of repairing the flue gas sampling cylinder 1. At the same time, by using the first semicircular ring 21 and the second semicircular ring 22 to place the repair ring 4 at the damaged position of the flue gas sampling cylinder 1, it is convenient to repair the damaged flue gas sampling cylinder 1.

[0022] like Figures 1 to 4As shown, both ends of the first semicircular ring 21 are provided with locking blocks 5, and both ends of the second semicircular ring 22 are provided with locking grooves 6. The locking blocks 5 are engaged with the locking grooves 6. Both ends of the first semicircular ring 21 are provided with sliding grooves 7. The locking blocks 5 are slidably installed inside the sliding grooves 7. A limit rod 8 is fixedly installed on the first semicircular ring 21 at the position corresponding to the sliding groove 7. The locking blocks 5 are slidably installed on the outside of the limit rod 8. A return spring 9 is sleeved on the outside of one end of the limit rod 8. One end of the return spring 9 is fixedly connected to one side of the locking block 5, and the other end of the return spring 9 is fixedly connected to one end of the first semicircular ring 21 corresponding to the sliding groove 7. One end of the locking block 5 is provided with a first inclined surface 10, and the end position of the second semicircular ring 22 corresponding to the locking groove 6 is provided with a second inclined surface 11. The first inclined surface 10 and the second inclined surface 11 are in pressing contact.

[0023] The first inclined surface 10 on the locking block 5 at the end of the first semicircular ring 21 is pressed against the second inclined surface 11 at the end of the locking groove 6 on the second semicircular ring 22, which will cause the locking block 5 to slide inside the sliding groove 7. At this time, the return spring 9 is in a compressed state, which can completely pass the locking block 5 through the locking groove 6. Then, under the push of the return spring 9 on the locking block 5, the locking block 5 will be locked in the locking groove 6, which facilitates the installation between the first semicircular ring 21 and the second semicircular ring 22.

[0024] like Figures 1 to 4 As shown, a bolt rod 12 is provided on the lower collar 2, the top end of the bolt rod 12 passes through the upper collar 2, and a nut 13 is provided on the top end of the bolt rod 12.

[0025] The distance between the two sets of collars 2 is adjusted by the cooperation of the bolt rod 12 and the nut 13, so that the repair collar 4 can be stably installed inside the mounting groove 3.

[0026] like Figures 1 to 4 As shown, a groove 14 is provided on the inner side of the repair ring sleeve 4, and a sealing rubber gasket 15 is installed on the repair ring sleeve 4 at the inner position corresponding to the groove 14.

[0027] By installing a sealing rubber gasket 15 on the inside of the repair ring 4, the damaged flue gas sampling cylinder 1 can be effectively sealed.

[0028] like Figures 1 to 4 As shown, fastening bolts 16 are arranged in a ring array around the central axis of the collar 2 on the surface of the collar 2.

[0029] By rotating the fastening bolt 16, the fastening bolt 16 will be driven to press the repair ring 4, which is used to fix the repair ring 4 and the collar 2.

[0030] like Figures 1 to 4 As shown, the end of the card block 5 corresponding to the first inclined surface 10 has a chamfer 17.

[0031] The chamfered corner 17 design makes it easy to pass the card block 5 through the card slot 6.

[0032] This utility model provides a stainless steel tube sleeve for repairing flue gas sampling cylinders, and its specific working principle is as follows:

[0033] When using the device, cut out a suitable repair ring 4 and place it between the mounting grooves 3 on the two sets of rings 2. Then, fit the first semicircular ring 21 and the second semicircular ring 22 onto the outside of the flue gas sampling cylinder 1. Adjust the distance between the two sets of rings 2 by cooperating with the bolt rod 12 and the nut 13 to stably install the repair ring 4 inside the mounting groove 3. Then, rotate the fastening bolt 16 to squeeze the repair ring 4, thus fixing the repair ring 4 to the rings 2. When installing the first semicircular ring 21 and the second semicircular ring 22, the first semicircular ring 21... The first inclined surface 10 on the locking block 5 at the end of the ring 21 will press the second inclined surface 11 at the end of the slot 6 on the second semi-circular ring 22, which will drive the locking block 5 to slide inside the slide groove 7. At this time, the return spring 9 is in a compressed state, which can be used to completely pass the locking block 5 through the slot 6. Then, under the push of the return spring 9 on the locking block 5, the locking block 5 will be driven to be locked on the slot 6, realizing the installation between the first semi-circular ring 21 and the second semi-circular ring 22, which is used to stably fix the collar 2 on the flue gas sampling cylinder 1. By repairing the position of the damaged position of the flue gas sampling cylinder 1 corresponding to the repair ring 4, the damaged position of the flue gas sampling cylinder 1 can be repaired.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
