Description

Technical Field

[0001] The utility model relates to the technical field of gas sampling probes, in particular to an air-cooled gas sampling probe for a gas analyzer. Background Technique

[0002] The gas sampling probe for the decomposition furnace of a cement plant is a key device used to collect gas samples inside the decomposition furnace during the cement production process. The gas sampling probe is inserted into the decomposition furnace through its specially designed sampling port or sampling pipe, and the gas sample in the furnace is sucked into the probe by using a suction pump or natural pressure difference. These probes usually need to work stably for a long time in high-temperature, high-dust and corrosive environments to ensure that the collected gas samples are representative and accurate. Since the gas sampling probe is inside the decomposition furnace, the continuous high temperature inside the decomposition furnace is likely to affect the service life of the gas sampling probe. Therefore, cooling the gas sampling probe is particularly crucial;

[0003] The existing gas sampling probes either adopt high-temperature resistant alloy materials for production or use the water-cooling method to cool the probe to extend the service life of the gas sampling probe;

[0004] The gas sampling probe made of high-temperature resistant alloy materials still has the problem of short service life under the continuous high temperature of the decomposition furnace, and the gas sampling probe made of refractory materials has a high cost, increasing the burden on enterprises;

[0005] The advantage of the water-cooled gas sampling probe technology is that it can effectively cool down, but there is a shortcoming that the cooling oil inside is prone to leakage. During daily maintenance, the cooling oil needs to be replaced regularly, and the maintenance workload is large. Moreover, if there is an oil leak, it is very difficult to find the leak point after removing the gas sampling probe. Therefore, an air-cooled gas sampling probe for a gas analyzer is designed to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to propose an air-cooled gas sampling probe for a gas analyzer to solve the problems existing in the above background technique.

[0007] The technical problem to be solved by the utility model is to provide an air-cooled gas sampling probe for a gas analyzer to solve the problems of high cost of refractory material probes and inconvenient maintenance of water-cooled probes in the prior art.

[0008] The utility model provides an air-cooled gas sampling probe for a gas analyzer, which includes a probe main body, a sample gas inlet, a sample gas outlet, an air-cooling pipe, an intake pipe, a turbocharger fan and an exhaust pipe. A sample gas inlet is opened on the left side surface of the probe main body, a sample gas outlet is opened at the right end of the probe main body, an air-cooling pipe is sleeved on the probe main body, an intake pipe penetrates through the upper part of the air-cooling pipe, a turbocharger fan is installed on the right side of the intake pipe, and an exhaust pipe penetrates through the bottom of the air-cooling pipe;

[0009] The air-cooled pipe includes a collar and a partition. Collars are fixedly arranged at both the left and right ends inside the air-cooled pipe, and partitions are fixedly arranged on both sides inside the air-cooled pipe.

[0010] Preferably, the inner diameter of the collar is equal to the outer diameter of the right side of the probe body, and the collar is welded to the outer surface of the probe body.

[0011] Preferably, one end of the partition away from the air-cooled pipe is welded to the outer surface of the probe body.

[0012] Preferably, the left end of the partition is welded to the left collar, and there is a spacing between the right end of the partition and the right collar.

[0013] Preferably, the partition separates the intake pipe and the exhaust pipe.

[0014] Preferably, an internal thread ring is fixedly arranged at the end of the intake pipe. A positioning bolt is threadedly connected above the internal thread ring. The outer surface of the turbo blower is provided with an external thread, and a bolt hole is provided on the outer surface of the turbo blower.

[0015] Preferably, the external thread on the turbo blower matches the internal thread ring, and the external thread is threadedly connected to the internal thread ring.

[0016] Preferably, when the external thread on the turbo blower is fully screwed into the internal thread ring, the bolt hole faces the positioning bolt, and the positioning bolt can be threadedly connected to the bolt hole.

[0017] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0018] 1. By setting an air-cooled pipe, when cooling the probe body, the turbo blower blows external air into the air-cooled pipe. The air above the air-cooled pipe is blocked by the partition, causing the air to move to the right along the air-cooled pipe until the right end of the partition, and then flowing into the lower part of the air-cooled pipe. The air flows to the left of the air-cooled pipe and is then discharged from the exhaust pipe. The air exchanges heat with the probe body, achieving the effect of dissipating heat from the probe body. The method of using air cooling to dissipate heat from the probe body is different from water cooling. Once water cooling is damaged, the coolant will flow everywhere, and there is no problem of leakage points. Once it is damaged, there is no need to search for leakage like cooling oil, which reduces the maintenance workload of on-site maintenance workers.

[0019] 2. The utility model is provided with an internal thread ring, a positioning bolt, an external thread and a bolt hole 402. When installing the turbocharged fan, the external thread is threadedly connected to the internal thread ring, and by tightening the positioning bolt which is threadedly connected to the bolt hole, the installation of the turbocharged fan can be realized. The installation is convenient. And when the turbocharged fan is damaged, by loosening the positioning bolt and screwing out the turbocharged fan from the internal thread ring, the repair or replacement of the turbocharged fan is convenient.

[0029] The air-cooled tube 2 includes a collar 201 and a partition 202. Collars 201 are fixedly arranged at both the left and right ends inside the air-cooled tube 2, and partitions 202 are fixedly arranged on both sides inside the air-cooled tube 2.

[0030] By providing the air-cooled tube 2, when cooling the probe body 1, the turbocharged blower 4 blows external air into the air-cooled tube 2. The air above the air-cooled tube 2 is blocked by the partition 202, causing the air to move along the air-cooled tube 2 to the right until the right end of the partition 202, and then flowing into the lower part of the air-cooled tube 2. The air flows to the left side of the air-cooled tube 2 and is then discharged from the exhaust pipe 5. The air exchanges heat with the probe body 1, achieving the effect of dissipating heat from the probe body. The method of using air cooling to dissipate heat from the probe body 1 does not have the problem that once it is damaged, the coolant will flow everywhere like water cooling, nor does it have a leakage point problem. Once it breaks, there is no need to search for leakage like cooling oil, which reduces the maintenance workload of on-site maintenance workers.

[0031] In this embodiment, the inner diameter of the collar 201 is equal to the outer diameter of the right side of the probe body 1, and the collar 201 is welded to the outer surface of the probe body 1.

[0032] In this embodiment, one end of the partition 202 away from the air-cooled tube 2 is welded to the outer surface of the probe body 1, facilitating the partition 202 to cooperate with the probe body 1 to divide the left side of the air-cooled tube 2 into upper and lower parts.

[0033] In this embodiment, the left end of the partition 202 is welded to the left collar 201, and there is a spacing between the right end of the partition 202 and the right collar 201, facilitating the air above the air-cooled tube 2 to flow from the right end of the partition 202 to the lower part of the air-cooled tube 2 and ensuring the fluidity of the air.

[0034] In this embodiment, the partition 202 separates the intake pipe 3 and the exhaust pipe 5, ensuring the distance of air flow and increasing the heat exchange between the air and the probe body 1.

[0035] In this embodiment, an internal thread ring 301 is fixedly arranged at the end of the intake pipe 3. A positioning bolt 302 is threadedly connected above the internal thread ring 301. An external thread 401 is arranged on the outer surface of the turbocharged blower 4, and a bolt hole 402 is opened on the outer surface of the turbocharged blower 4.

The installation is convenient. And when the turbocharged fan 4 is damaged, by loosening the positioning bolt 302, the turbocharged fan 4 can be screwed out from the internal thread ring 301, which is convenient for the maintenance or replacement of the turbocharged fan 4.

[0039] The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
