Description

Technical Field

[0001] This invention relates to the field of air separation equipment technology, specifically to an air separation device that facilitates the installation of a gas purity detection probe. Background Technology

[0002] Air separation equipment is a gas separation device that liquefies, distills, and ultimately separates air into oxygen, nitrogen, and other useful gases. Air separation equipment was initially used only in the gas welding and cutting of metals. In order to improve the quality of the separated gases, it is necessary to use gas purity detection probes for detection.

[0003] Publication No. CN220834674U discloses an air separation device that facilitates the installation of a gas purity detection probe. The main installation mechanism allows for easy installation and removal of the probe, ensuring the purity of the separated gas and guaranteeing its quality. The protective housing provides some protection for the probe, while clamping plates secure it. Rubber pads prevent wear on the probe's surface. A gas delivery mechanism facilitates the transport of separated gas into the protective housing and allows for the return of any unseparated gas to the air separation device. However, this patent has the following problems in practical use:

[0004] Although this air separation device, which facilitates the installation and removal of the gas purity detection probe, has a main installation mechanism, the probe's position is fixed. During air testing, due to the different densities and specific gravities of various gases, some gases with a density greater than air will sink, while others with a density less than air will float on top of the protective casing. This can lead to inaccurate detection by the probe, affecting the accuracy of the test data.

[0005] Therefore, an air separation device that facilitates the installation of a gas purity detection probe is proposed to address the aforementioned problems. Summary of the Invention

[0006] The purpose of this invention is to provide an air separation device that facilitates the installation of a gas purity detection probe, thereby solving the problem mentioned in the background art where the position of the detection probe is fixed. During air detection, due to the different densities and specific gravities of different gases, some gases with a density greater than air will sink, while others with a density less than air will float on top of the protective box.

[0021] Compared with the prior art, the beneficial effects of this invention are: This air separation device facilitates the installation of a gas purity detection probe, enabling the rotating bracket to rotate vertically, thus facilitating comprehensive detection of the gas inside the detection cylinder. It avoids gas accumulation at the bottom or top of the detection cylinder due to the gas's density being greater or less than air, which could affect the detection accuracy of the probe. The device utilizes a storage motor to drive the sprocket transmission assembly and the storage rotating rod, which in turn drives the universal wheels. When the entire air separation device needs to be moved, the universal wheels can be lowered for easy movement. The specific details are as follows:

[0022] 1. By setting up the detection mechanism, the cleaning supports on both sides of the detection cylinder can be used to clean the detection probe body, preventing dust from adhering to the surface of the detection probe body and affecting the detection accuracy. By starting the rotating motor, the main rotating gear rotates. Utilizing the meshing connection between the main rotating gear, the driven rotating gear, and the meshing gear ring, the meshing gear ring drives the first rotating disk and the first connecting rod to rotate. Simultaneously, the first connecting rod drives the second rotating disk and the second connecting rod to rotate. The second connecting rod drives the first rotating gear to rotate. Utilizing the meshing connection between the first and second rotating gears, the second rotating gear drives the third rotating gear to rotate. This allows the third rotating gear to rotate the rotating support horizontally. Simultaneously, the rotating main gear drives the rotating connecting shaft and the support sleeve to rotate, enabling the rotating support to rotate vertically. This facilitates omnidirectional detection of the gas inside the detection cylinder and avoids gas accumulation in the detection cylinder due to the gas's density being greater or less than air. The bottom or top position affects the detection accuracy of the detection probe body. Since the rotation direction of the main gear is different from that of the first and second rotating disks, the first and second rotating gears can rotate in opposite directions, thus enabling the rotating bracket to rotate. This allows the detection probe body to rub against the cleaning brush inside the cleaning bracket, effectively cleaning the dust adsorbed on the surface of the detection probe body and improving its detection accuracy. By inserting the limiting blocks on both sides of the detection probe body into the horizontal rotating slot through the limiting slot inside the rotating bracket, the horizontally rotating detection probe body passes over the limiting spring for limitation. Simultaneously, under the action of the compression spring and compression ring, the detector can be pressed and fixed, facilitating quick installation and removal. By rotating the actuating block at the top of the mounting threaded block, the mounting threaded block and the first exhaust pipe can be removed from the top of the detection cylinder, facilitating the disassembly of the detector and the detection probe body. The first fan inside the first exhaust pipe enables gas extraction.

[0023] 2. By setting up an air separation mechanism, not only can the air separation device inside the equipment box be used for air separation, but the connecting hinges and fixing bolts can also open the sealing cover to facilitate the maintenance and replacement of the air separation device. By starting the second fan on one side of the circulation pipe, the unseparated gas can be sent back into the equipment box for secondary separation. The storage motor drives the sprocket transmission assembly and the storage rotating rod to rotate, which in turn drives the universal wheels to rotate. When it is necessary to move the entire air separation device, the universal wheels can be lowered to move the air separation device. When it is necessary to stabilize the air separation device, the universal wheels can be stored in the storage slot to facilitate the movement and stable support of the air separation device.

An air separation mechanism 2 is provided at the bottom of the detection mounting mechanism 1, and a sealing cover 204 is provided at the top of the air separation mechanism 2. The detection mounting mechanism 1 includes a detection cylinder 101, with an air inlet 102 at the center of the bottom of the detection cylinder 101 and a circulation hole 103 on one side of the bottom of the detection cylinder 101. Cleaning brackets 104 are symmetrically mounted on both sides inside the detection cylinder 101, and fixed connecting rods 105 are fixedly mounted on both sides of the detection cylinder 101 away from the cleaning brackets 104. The ends of the fixed connecting rods 105 are fixedly mounted... A support plate 106 is provided. A rotating motor 107 is fixedly installed inside a connecting rod 105 on one side. A rotating main gear 108 is fixedly connected to the output end of the rotating motor 107. A rotating driven gear 109 is meshed with the outer side of the rotating main gear 108. A meshing gear ring 110 is meshed with the outer side of the rotating driven gear 109. The meshing gear ring 110 is rotatably connected to the support plate 106. The rotating driven gear 109 is rotatably connected to the support plate 106. A first rotating disk 111 is fixedly installed on one side of the meshing gear ring 110. Several first connecting rods 112 are fixedly installed on one side of the first rotating disk 111. A second rotating disk 113 is fixedly installed at the end of each first connecting rod 112. Several second connecting rods 113 are fixedly installed on one side of the second rotating disk 113. A connecting rod 114 is connected to a first rotating gear 115 at one end. A rotating connecting shaft 116 is fixedly connected to one side of the main rotating gear 108. The rotating connecting shaft 116 is rotatably connected to the first rotating disk 111, the second rotating disk 113, and the first rotating gear 115. A support sleeve 117 is fixedly connected to the end of the rotating connecting shaft 116. A second rotating gear 118 is rotatably connected to the middle of the rotating connecting shaft 116. The second rotating gear 118 meshes with the first rotating gear 115. A third rotating gear 119 is meshed with the side of the second rotating gear 118 away from the first rotating gear 115. A rotating bracket 120 is fixedly installed at the bottom of the third rotating gear 119. The detection cylinder 101 is used to... The cleaning brackets 104 on both sides of the interior can clean the detection probe body 127, preventing dust from adhering to the surface of the detection probe body 127 and affecting the detection accuracy of the detection probe body 127. By starting the rotating motor 107, the rotating main gear 108 is driven to rotate. Utilizing the meshing connection between the rotating main gear 108, the rotating driven gear 109, and the meshing gear ring 110, the meshing gear ring 110 can drive the first rotating disk 111 and the first connecting rod 112 to rotate. At the same time, the first connecting rod 112 drives the second rotating disk 113 and the second connecting rod 114 to rotate. The second connecting rod 114 drives the first rotating gear 115 to rotate. Utilizing the meshing connection between the first rotating gear 115 and the second rotating gear 118...The second rotating gear 118 drives the third rotating gear 119 to rotate, which in turn causes the third rotating gear 119 to drive the rotating support 120 to rotate horizontally.

[0038] Please see Figures 4-6 The rotating bracket 120 has limit slots 121 on both sides inside. A horizontal rotation groove 122 is formed at the top of the rotating bracket 120 near the limit slots 121. A limit spring 123 is fixedly installed in the middle of the rotating bracket 120 near the horizontal rotation groove 122. Compression springs 124 are fixedly installed around the bottom of the rotating bracket 120. A compression ring 125 is fixedly installed at the bottom of the compression springs 124. A detector 126 is set at the bottom of the compression ring 125. A detection probe body 127 is fixedly installed at the top center of the detector 126. Rotating the main gear 108 drives the rotating connecting shaft 116 and the support sleeve 117 to rotate, enabling the rotating bracket 120 to rotate vertically, facilitating the movement of the detection cylinder 10. The internal gas is detected from all directions to avoid gas accumulation at the bottom or top of the detection cylinder 101 due to the gas density being greater or less than that of air, which would affect the detection accuracy of the detection probe body 127. At the same time, since the rotation direction of the main rotating gear 108 is different from the rotation direction of the first rotating disk 111 and the second rotating disk 113, the first rotating gear 115 and the second rotating gear 118 can rotate in opposite directions, thereby enabling the rotation of the rotating bracket 120. This allows the detection probe body 127 to rub against the cleaning brush inside the cleaning bracket 104, which can clean the dust adsorbed on the surface of the detection probe body 127 and improve the detection accuracy of the detection probe body 127.

[0039] Please see Figures 6-7Limiting blocks 128 are symmetrically installed on both sides of the middle of the detection probe body 127. The limiting blocks 128 are slidably connected to the horizontal rotating groove 122. The top of the detection cylinder 101 is threadedly connected to the mounting thread block 129. Several actuating blocks 130 are fixedly installed on the outer side of the top of the mounting thread block 129. The top of the mounting thread block 129 is fixedly installed with a first exhaust pipe 131. The top of the first exhaust pipe 131 is fixedly installed with a first filter screen 132. The inside of the first exhaust pipe 131 is fixedly installed with a first fan 133. By passing the limiting blocks 128 on both sides of the detection probe body 127 through the limiting slots 122 inside the rotating bracket 120, the detection probe body 127 can be connected to the horizontal rotating groove 122. 21 is inserted into the horizontal rotating slot 122, and at the same time, the horizontally rotating detection probe body 127 passes over the limiting spring 123 for limitation. Under the action of the compression spring 124 and the compression ring 125, the detector 126 can be pressed and fixed, which facilitates the quick installation and removal of the detector 126. By rotating the toggle block 130 on the top of the mounting threaded block 129, the mounting threaded block 129 and the first exhaust pipe 131 can be removed from the top of the detection cylinder 101, which facilitates the removal of the detector 126 and the detection probe body 127. The first fan 133 inside the first exhaust pipe 131 can achieve gas extraction.

[0040] Please see Figures 8-11The air separation mechanism 2 includes an equipment box 201, inside which the air separation device body 202 is fixedly installed. Connecting hinges 203 are symmetrically installed on one side of the top of the equipment box 201. A sealing cover 204 is rotatably connected to the connecting hinges 203. The sealing cover 204 is fixedly installed at the bottom of the detection cylinder 101. Fixing blocks 205 are fixedly installed on one side and one side of the top of the sealing cover 204. Fixing bolts 206 are threaded into the fixing blocks 205. An air inlet valve 207 is fixedly installed on one side of the bottom of the equipment box 201. The center of the bottom of the sealing cover 204 is connected to the equipment... A second exhaust pipe 209 is fixedly installed on one side of the interior of the box 201. A circulation pipe 208 is fixedly installed on the outside of the second exhaust pipe 209 at the bottom. The circulation pipe 208 is fixedly installed on one side of the circulation hole 103. A second fan 210 is fixedly installed inside the second exhaust pipe 209. A second filter screen 211 is fixedly installed at the end of the second exhaust pipe 209. A support base 212 is fixedly installed at the bottom of the equipment box 201. Support legs 213 are fixedly installed around the bottom of the support base 212. A storage groove 214 is opened around the inside of the support base 212. An electric motor is fixedly installed on one side of the support base 212. Inside the machine housing 215, a storage motor 216 is fixedly installed on one side. A sprocket drive assembly 217 is fixedly connected to the output end of the storage motor 216. A storage rotating rod 218 is symmetrically connected to one side of the sprocket drive assembly 217. Storage rotating sleeves 219 are symmetrically installed on the outer sides of the storage rotating rods 218. A caster wheel 220 is fixedly installed at the bottom of the storage rotating sleeve 219. Air separation is achieved using the air separation device body 202 inside the equipment box 201. Simultaneously, the connecting hinge 203 and fixing bolts 206 allow the sealing cover 204 to be opened, facilitating access to the air separation device body. For the maintenance and replacement of 202, the unseparated gas can be re-sent to the equipment box 201 for secondary separation by starting the second fan 210 on one side of the circulation pipe 208. The storage motor 216 drives the sprocket transmission assembly 217 and the storage rotating rod 218 to rotate, which causes the storage rotating sleeve 219 to drive the caster wheel 220 to rotate. When it is necessary to move the entire air separation equipment, the caster wheel 220 can be lowered to move the air separation equipment. When it is necessary to stabilize the air separation equipment, the caster wheel 220 can be stored in the storage slot 214 to facilitate the movement and stable support of the air separation equipment.

[0041] Working Principle: Before using this air separation device that facilitates the installation of gas purity detection probes, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 11As shown, firstly, the air separation device body 202 inside the equipment box 201 is used for air separation. At the same time, the connecting hinge 203 and fixing bolt 206 can open the sealing cover 204 to facilitate the maintenance and replacement of the air separation device body 202. By starting the second fan 210 on one side of the circulation pipe 208, the unseparated gas can be transported back into the equipment box 201 for secondary separation. The storage motor 216 drives the sprocket transmission assembly 217 and the storage rotating rod 218 to rotate, so that the storage rotating sleeve 219 drives the universal wheel 220 to rotate. When it is necessary to move the entire air separation device, the universal wheel 220 can be lowered to move the air separation device. When it is necessary to stabilize the air separation device, the universal wheel 220 can be stored in the storage slot 214 to facilitate the movement and stable support of the air separation device.

[0042] Secondly, the cleaning brackets 104 on both sides inside the detection cylinder 101 can clean the detection probe body 127, preventing dust from adhering to the surface of the detection probe body 127 and affecting the detection accuracy of the detection probe body 127. By starting the rotating motor 107, the rotating main gear 108 is driven to rotate. Utilizing the meshing connection between the rotating main gear 108, the rotating driven gear 109, and the meshing gear ring 110, the meshing gear ring 110 can drive the first rotating disk 111 and the first connecting rod 112 to rotate. At the same time, the first connecting rod 112 drives the second rotating disk 113 and the second connecting rod 114 to rotate. The second connecting rod 114 drives the first rotating gear 115 to rotate. Utilizing the meshing connection between the first rotating gear 115 and the second rotating gear 118, the second rotating gear 118 drives the third rotating gear 119 to rotate, which in turn drives the rotating bracket 120. The horizontal rotation of the main gear 108, which in turn drives the rotating connecting shaft 116 and the support sleeve 117, enables the rotating bracket 120 to rotate vertically. This facilitates comprehensive detection of the gas inside the detection cylinder 101, preventing gas accumulation at the bottom or top of the detection cylinder 101 due to the gas's density being greater or less than air, which could affect the detection accuracy of the detection probe body 127. Furthermore, since the rotation direction of the main gear 108 differs from that of the first rotating disk 111 and the second rotating disk 113, the first rotating gear 115 and the second rotating gear 118 rotate in opposite directions. This allows the rotating bracket 120 to rotate, causing the detection probe body 127 to rub against the cleaning brush inside the cleaning bracket 104. This effectively removes dust adsorbed on the surface of the detection probe body 127, improving its detection accuracy.

[0043] Finally, by inserting the limiting blocks 128 on both sides of the detection probe body 127 into the horizontal rotation groove 122 through the limiting slots 121 inside the rotating bracket 120, the detection probe body 127 is horizontally rotated past the limiting spring 123 for limiting. At the same time, under the action of the compression spring 124 and the compression ring 125, the detector 126 can be pressed and fixed, which facilitates the quick installation and removal of the detector 126. By rotating the actuating block 130 on the top of the mounting threaded block 129, the mounting threaded block 129 and the first exhaust pipe 131 can be removed from the top of the detection cylinder 101, which facilitates the removal of the detector 126 and the detection probe body 127. The first fan 133 inside the first exhaust pipe 131 can achieve gas extraction.
