Description

Technical Field

[0001] This utility model belongs to the technical field of high-temperature gas sampling devices, and relates to a high-temperature gas sampling device that is easy to maintain. Background Technology

[0002] Existing high-temperature gas sampling equipment (such as gas inside a cement kiln), such as Figure 1 As shown, the device typically includes a mounting frame 100, a sampling rod 101, a filter head 102, a transmission device 103, and a power unit 104. The device is fixed at a suitable distance near the sampling area by the mounting frame 100. The power unit outputs power, which drives the sampling rod through the transmission device to insert it into the furnace to extract gas. Upon completion of sampling, the power unit outputs power, which drives the sampling rod out of the furnace through the transmission device. The high-temperature gas enters the sampling probe and is cooled by its internal coolant before passing through the filter head into the system for analysis.

[0003] Another method for high-temperature gas sampling is to insert a sampling probe made of high-temperature resistant material into the furnace and fix it in place, while continuously cooling the probe through a cooling circulation system. Since the gas being measured is high-temperature gas, and the sampling environment is at 1000–1500°C, even with a cooling circulation system, sampling probes made of ordinary materials cannot withstand the high temperatures for extended periods. Furthermore, sampling probes made of high-temperature resistant materials are not only expensive to produce, but are also prone to damage or malfunction after prolonged use in high-temperature environments.

[0004] The sampling probes of current mainstream equipment integrate cooling systems, transmission systems, electrical systems, etc., which require complete disassembly during fault repair, and the debugging process after repair is time-consuming. Summary of the Invention

[0005] The technical problem solved by this utility model is to provide a high-temperature gas sampling device that is easy to maintain, and the sampling probe can be quickly disassembled without disassembling the entire device, thus saving time and costs.

[0006] This utility model is achieved through the following technical solution:

[0007] A high-temperature gas sampling device that is easy to maintain includes a support frame consisting of a guide crossbar and a support column. A transmission box is nested on the guide crossbar by multiple guide wheels. The transmission box is also equipped with a transmission gear that meshes with one of the guide wheels. The transmission gear is connected to the output shaft of the power unit. The power unit can drive the transmission box to reciprocate on the guide crossbar through the transmission gear.

[0008] The upper end of the support column is equipped with rollers, the front end of the sampling probe is mounted on the rollers, and the rear end of the sampling probe is fixed to the transmission box by a fixing seat.

[0009] Furthermore, the fixing base includes a pressure plate and screws, and the two short shafts on the side of the sampling probe are respectively fixed to the transmission box by two pressure plates and their screws.

[0010] Furthermore, the inner wall of the sampling probe is provided with a cavity, and the coolant enters the cavity of the inner wall of the sampling probe through the inlet pipe joint and flows out through the outlet pipe joint.

[0011] Furthermore, the filter device is fixed to the end of the sampling probe.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] Since the sampling probe operates in a high-temperature environment for a long time, it requires frequent maintenance. The high-temperature gas sampling device provided by this utility model is easy to maintain. The sampling probe and the filter device are independent structures with little coupling to the transmission box. The sampling probe can be quickly disassembled without disassembling the entire sampling device, which facilitates maintenance and replacement and saves time and costs. Attached Figure Description

[0019] See Figures 2-4 A high-temperature gas sampling device that is easy to maintain includes a support frame consisting of a guide crossbar and a support column. A transmission box is nested on the guide crossbar by multiple guide wheels. The transmission box is also equipped with a transmission gear that meshes with one of the guide wheels. The transmission gear is connected to the output shaft of the power unit. The power unit can drive the transmission box to reciprocate on the guide crossbar through the transmission gear.

[0020] The upper end of the support column is equipped with rollers, the front end of the sampling probe is mounted on the rollers, and the rear end of the sampling probe is fixed to the transmission box by a fixing seat.

[0021] Furthermore, the fixing base includes a pressure plate and screws, and the two short shafts on the side of the sampling probe are respectively fixed to the transmission box by two pressure plates and their screws.

[0022] The support frame is used to fix the equipment. The power unit and transmission box can reciprocate on the support frame. The sampling probe and filter device are fixed to the transmission box by screws and pressure plates and can reciprocate together with it. At the same time, a roller at the front of the sampling probe can provide support and guidance. The two joints on the probe are connected to the inlet and outlet pipes of the coolant, respectively.

[0023] Connection method between sampling probe and transmission box: The short shaft on the side of the probe is fixed to the transmission box with a pressure plate and screws, which can achieve quick assembly and disassembly.

[0024] The front end of the sampling probe has a roller that provides guidance and support during its reciprocating motion, allowing for quick assembly and disassembly.

[0025] Furthermore, the inner wall of the sampling probe is provided with a cavity, and the coolant enters the cavity of the inner wall of the sampling probe through the inlet pipe joint and flows out through the outlet pipe joint.

[0026] Furthermore, the filter device is fixed to the end of the sampling probe.

[0027] Specific implementation examples are given below.

[0028] like Figure 2 , Figure 3 As shown, a high-temperature gas sampling device that is easy to maintain includes a support frame 200 consisting of a guide crossbar and a support column, as well as a sampling probe 201, a filter device 202, a transmission box 203, and a power unit 204; wherein, the transmission box 203 is mounted on the guide crossbar and is connected to and driven by the power unit 204.

[0029] like Figure 4 As shown, the transmission box 203 is equipped with a transmission gear 2031, a lower right guide wheel 20321 and a lower left guide wheel 20322; an upper right guide wheel 20331 and an upper left guide wheel 20332;

[0030] The power unit 204 outputs power, which is driven by the transmission box 203 and makes it reciprocate on the guide bar;

[0031] Meanwhile, the two short shafts on the side of the sampling probe 201 are fixed to the transmission box 203 by two pressure plates 2011 and their screws 2012, and are driven by them to reciprocate. The front of the sampling probe 201 is supported by rollers 2013 on the support column. The filter device 202 is fixed behind the sampling probe 201. Coolant enters the cavity inside the sampling probe 201 through the liquid inlet pipe joint 2014 and flows out through the liquid outlet pipe joint 2015.

[0032] During equipment maintenance, simply loosen screw 2012, remove pressure plate 2011, and loosen cooling pipe joints (including inlet pipe joint 2014 and outlet pipe joint 2015) to remove the entire sampling probe 201 for maintenance or replacement.
