Description

Technical Field

[0001] This invention relates to the field of coated catalyst testing technology, specifically to a device for observing the effect of coated catalysts. Background Technology

[0002] In the development of honeycomb catalyst technology, it is necessary to adjust the process and conduct process experiments according to the formulation requirements. During the research and development process, different carrier specifications and coating parameters will affect various indicators of the finished catalyst. After the catalyst is finished, it is necessary to test the catalyst coating effect in the pores of the carrier. Currently, in the experiment, the catalyst coating effect can be visually inspected. During operation, the operator holds the carrier up to the light source and observes the catalyst coating effect in each pore, which is laborious, time-consuming, and may even lead to incomplete observation of the catalyst coating effect in the pores due to light irradiation issues.

[0003] Publication No. CN216900273U discloses a catalyst coating effect observation device. A light source assembly is installed inside the light chamber, and a light shield is installed at the top opening of the light chamber. The light shield blocks strong light, solving the problem of excessive light source causing eye irritation. Furthermore, the light source covers a large area, and the light shield is suitable for observing the catalyst pore coating over a wide area, solving the problem of observing each pore individually and avoiding the problem of the catalyst searching for the light source. Operation is convenient and simple. Multiple snap-fit ​​parts are provided on the inner wall of the light chamber, and the end of the mounting plate is fixedly installed in the cavity of the light chamber through these snap-fit ​​parts. The installation height of the mounting plate is controllable, and correspondingly, the distance between the light source assembly on the mounting plate and the light shield is adjustable, making the position adjustment of the light source assembly convenient. However, this patent still has the following problems in actual use:

[0004] Although the catalyst coating effect observation device can improve the observation effect by adjusting the distance between the light and the honeycomb carrier, it can only observe the uniformity and coverage of the film with the naked eye, and cannot accurately detect whether the coated catalyst particles are evenly distributed. At the same time, the existing technology uses scanning electron microscopes or optical microscopes for observation, but the edges of the honeycomb carrier are easily blocked when fixing the honeycomb carrier, making the edges impossible to observe, thus affecting the observation effect of the honeycomb carrier.

[0005] Therefore, a device for observing the effects of coated catalysts is proposed to address the problems mentioned above. Summary of the Invention

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] This device for observing the effect of coated catalysts allows for the support of honeycomb carriers of different sizes by adjusting the distance between two limiting rotating plates. Under the elastic force of the compression spring, the clamping block presses and fixes the sides of the honeycomb carrier. Simultaneously, the limiting rotating plates rotate to a vertical position, exposing the bottom of the honeycomb carrier and preventing it from obstructing the bottom, thus affecting the illumination and observation of the obstructed areas. Activating the adjusting motor drives the second adjusting threaded rod to rotate, causing the adjusting threaded sleeve to move the observation lamp under the action of the adjusting limiting plate, allowing for adjustment of the observation lamp's position and facilitating all-around illumination. A connecting hinge allows the light shield to be opened or closed. Adjusting the angle of the light shield facilitates visual observation of the honeycomb carrier. When observation through the electron microscope body is required, the locking hook and fixing block can be used to close the light shield and observation box, providing a sealed environment. The specific details are as follows:

[0023] 1. By setting a fixed adjustment mechanism, not only can the first adjusting threaded rod drive the lifting bracket and the translation bracket to move relative to each other inside the observation box, but by adjusting the distance between the two limiting rotating plates, it is convenient to support honeycomb carriers of different sizes. By rotating the lifting knob, the lifting threaded rod is driven to rotate, so that the lifting threaded sleeve drives the first rotating bracket and the limiting support plate to move up and down. Under the action of the pressing rotating rod, the limiting rotating plate can be rotated. Under the action of the pressing spring, the pressing block is pressed and fixed on the side of the honeycomb carrier. At the same time, when the limiting rotating plate rotates to the vertical position, the bottom of the honeycomb carrier can be exposed, avoiding the limiting rotating plate from blocking the bottom of the honeycomb carrier, thereby affecting the lighting and observation of the part of the honeycomb carrier that is blocked.

[0024] By rotating the tilt knob, the first bevel gear transmission assembly and the tilt threaded rod are driven to rotate, so that the tilt threaded sleeve moves on the outside of the tilt threaded rod while the tilt rotating rod rotates, thereby adjusting the tilt angle of the limiting support plate, which is convenient for limiting support of honeycomb carriers of different thicknesses.

[0025] By starting the support motor, the first sprocket transmission assembly and the support rotating rod are driven to rotate, which in turn causes the second bevel gear transmission assembly to drive the support threaded rod to rotate. Under the action of the support top plate, the support lifting plate can be raised and lowered on the outside of the support threaded rod, which can adjust the distance between the observation lamp and the honeycomb carrier, making it easier to observe the honeycomb carrier.

[0026] By starting the first rotating motor, the rotating gear is driven to rotate. Utilizing the meshing connection between the rotating gear and the meshing gear, the adjustment disc can be rotated. Simultaneously, starting the adjustment motor drives the second adjusting threaded rod to rotate, causing the adjusting threaded rod to move the observation lamp under the action of the adjusting limit disc. This allows for adjustment of the observation lamp's position, facilitating omnidirectional illumination. By starting the second rotating motor, the rotating worm gear is driven to rotate. Utilizing the meshing connection between the rotating worm gear and the rotating worm wheel, the rotating worm wheel causes the rotating lamp holder to rotate horizontally. Simultaneously, starting the third rotating motor drives the observation lamp to rotate vertically, allowing for adjustment of the observation lamp's angle. This facilitates illumination of the honeycomb carrier from different directions, improving the observation effect.

[0027] 2. By setting up a light-shielding detection mechanism, the light shield can be opened or closed using a connecting hinge. By adjusting the angle of the light shield, it is convenient to observe the honeycomb carrier with the naked eye. When observation is required through the electron microscope body, the light shield and observation box can be sealed by the locking hook and the fixed block, providing a closed environment and avoiding external factors from affecting the observation of the honeycomb carrier. By starting the translation motor, the second sprocket transmission assembly and the translation threaded rod are rotated, which causes the translation threaded sleeve to move the longitudinal support horizontally. At the same time, the longitudinal motor is started to rotate the longitudinal threaded rod, which causes the longitudinal threaded sleeve to move the microscope probe longitudinally under the action of the longitudinal limiting plate. This enables the microscope probe to move in all directions, which is convenient for the observation of the honeycomb carrier. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1-6 The present invention provides a technical solution: an observation device for the effect of coating catalyst, including a fixing and adjusting mechanism 1 and a fixing base 120 installed at the bottom of the fixing and adjusting mechanism 1. A light-shielding detection mechanism 2 is provided on the top of the fixing and adjusting mechanism 1, and an electron microscope body 215 is provided on the top of the light-shielding detection mechanism 2.

[0042] The fixed adjustment mechanism 1 includes an observation box 101. Two fixed blocks 102 are installed on one side of the top of the observation box 101. The two fixed blocks 102 are symmetrically arranged about the vertical center line of the side wall of the observation box 101. The middle two sides of the observation box 101 are threadedly connected to a first adjusting threaded rod 103. The end of the first adjusting threaded rod 103 is rotatably connected to a lifting bracket 104, which is located inside the observation box 101.

[0043] The lifting bracket 104 is equipped with a first rotating bracket 108 through an up-down adjustment mechanism. The first rotating bracket 108 is equipped with an inclined rotating rod 113 through an inclined angle adjustment mechanism. The end of the inclined rotating rod 113 is rotatably connected to a limit support plate 114. The limit support plate 114 is rotatably connected to the first rotating bracket 108.

[0044] A limiting support plate 114 is rotatably connected to the bottom inner side of a limiting rotating plate 115. The limiting rotating plates 115 on the two limiting support plates 114 are arranged opposite to each other. Several compression springs 116 are fixedly installed on one side of the top of the limiting rotating plate 115. Compression blocks 117 are fixedly installed at the ends of the compression springs 116. The space between the compression blocks 117 on the two limiting rotating plates 115 is a honeycomb carrier clamping space.

[0045] Two pressing rotating rods 118 are rotatably connected to one side of the bottom of the limiting rotating plate 115. The ends of the pressing rotating rods 118 are rotatably connected to the translation brackets 119, which are fixedly installed at the bottom of the lifting bracket 104.

[0046] In this embodiment, the up-down adjustment mechanism includes a lifting knob 105 rotatably connected to the top of the lifting bracket 104. A lifting threaded rod 106 is fixedly installed at the bottom of the lifting knob 105. The lifting threaded rod 106 is vertically arranged. A lifting threaded sleeve 107 is threadedly connected to the outer side of the lifting threaded rod 106. The lifting threaded sleeve 107 slides vertically with the lifting bracket 104. One side of the lifting threaded sleeve 107 extends out of the lifting bracket 104 and is fixedly installed with a first rotating bracket 108.

[0047] The tilt angle adjustment mechanism includes a tilt knob 109 rotatably connected to the top side of the first rotating bracket 108, a first bevel gear transmission assembly 110 fixedly mounted at the bottom of the tilt knob 109, a tilt threaded rod 111 fixedly mounted on the first bevel gear transmission assembly 110, a tilt threaded sleeve 112 threadedly connected to the outer side of the tilt threaded rod 111, and a tilt rotating rod 113 rotatably connected to the bottom of the tilt threaded sleeve 112.

[0048] Rotating the first adjusting threaded rod 103 causes the lifting bracket 104 and the translation bracket 119 to move relatively closer together inside the observation box 101, adjusting the distance between the two limiting rotating plates 115. This facilitates support for honeycomb carriers of different sizes. Rotating the lifting knob 105 causes the lifting threaded rod 106 to rotate, causing the lifting threaded sleeve 107 to move the first rotating bracket 108 and the limiting support plate 114 upwards. Under the connection of the pressing rotating rod 118, the limiting rotating plate 115 can be rotated. Under the elastic force of the pressing spring 116, the pressing block 117 presses and fixes the side of the honeycomb carrier, while limiting the movement. When the rotating plate 115 is rotated to a vertical position, the bottom of the honeycomb carrier is exposed, preventing the limiting rotating plate 115 from blocking the bottom of the honeycomb carrier and thus affecting the lighting and observation of the blocked part of the honeycomb carrier. By rotating the tilt knob 109, the first bevel gear transmission assembly 110 and the tilt threaded rod 111 are driven to rotate, so that the tilt threaded sleeve 112 moves outside the tilt threaded rod 111 while the tilt rotating rod 113 is rotated, thereby adjusting the tilt angle of the limiting support plate 114, which is convenient for limiting and supporting honeycomb carriers of different thicknesses. The first bevel gear transmission assembly 110 consists of two bevel gears arranged perpendicularly to each other, which can realize the transmission function.

[0049] Please see Figure 2 , Figures 7-8 A fixed base 120 is fixedly installed at the bottom of the observation box 101. A first sprocket limiting cover 121 is fixedly installed on one side of the fixed base 120. A support motor 122 is fixedly installed on one side inside the first sprocket limiting cover 121.

A support rotating rod 124 is symmetrically installed on one side of the first sprocket transmission assembly 123. A second bevel gear transmission assembly 125 is symmetrically installed on the outer side of each of the two support rotating rods 124. A support threaded rod 126 is fixedly installed on the top of each of the four second bevel gear transmission assemblies 125. A support top plate 127 is rotatably connected to the top of the support threaded rod 126. The support top plate 127 is symmetrically installed on both sides inside the observation box 101.

[0050] Four supporting threaded rods 126 are threadedly connected to a supporting lifting plate 128. A first rotating motor 129 is fixedly installed on one side of the top of the supporting lifting plate 128. A rotating gear 130 is fixedly connected to the output end of the first rotating motor 129. A meshing gear 131 is meshed with one side of the rotating gear 130. The meshing gear 131 is rotatably connected to the supporting lifting plate 128. An adjusting plate 132 is fixedly installed on the top of the meshing gear 131. An adjusting motor 133 is fixedly installed on one side of the adjusting plate 132.

An adjusting threaded sleeve 135 is threadedly connected to the outer side of the second adjusting threaded rod 134. An adjusting limit plate 136 is fixedly installed on the top of the adjusting threaded sleeve 135.

[0051] The support motor 122 is started, driving the support rotating rod 124 to rotate via the first sprocket transmission assembly 123. This, in turn, drives the support threaded rod 126 to rotate via the second bevel gear transmission assembly 125. Under the action of the support top plate 127, the support lifting plate 128 can be raised and lowered, adjusting the distance between the observation lamp 143 and the honeycomb carrier for easier observation. The first rotating motor 129 is started, driving the rotating gear 130 to rotate. Utilizing the meshing connection between the rotating gear 130 and the meshing gear 131, the adjustment disc 13 can be adjusted. The rotation of 2 simultaneously starts the adjusting motor 133, which drives the second adjusting threaded rod 134 to rotate. This causes the adjusting threaded sleeve 135 to move the observation lamp 143 under the limiting and guiding action of the adjusting limit plate 136. This allows for adjustment of the position of the observation lamp 143, facilitating all-around illumination. The supporting rotating rod 124 is symmetrically arranged on both sides of the first sprocket transmission assembly 123 with respect to the central axis of the chain. The second bevel gear transmission assembly 125 is symmetrically arranged on both sides of the supporting rotating rod 124 with respect to the central axis of the supporting rotating rod 124.

The second rotating motor 138 is started to drive the rotating worm 139 to rotate. Utilizing the meshing connection between the rotating worm 139 and the rotating worm gear 140, the rotating worm gear 140 drives the rotating lamp holder 141 to rotate horizontally. At the same time, the third rotating motor 142 is started to drive the observation lamp 143 to rotate. The angle of the observation lamp 143 can be adjusted to facilitate different orientations of the honeycomb carrier and improve the observation effect. The second rotating bracket 137 is symmetrically installed on one side of the adjusting limit plate 136 with the central axis position of the adjusting limit plate 136.

[0053] Please see Figure 1 , Figures 9-10 The light-shielding detection mechanism 2 includes a light-shielding cover 201. A connecting hinge 202 is installed on one side of the light-shielding cover 201, which is connected to the observation box 101. A second sprocket limit cover 203 is fixedly installed on one side of the light-shielding cover 201. The connecting hinge 202 facilitates the opening or closing of the light-shielding cover 201. By adjusting the angle of the light-shielding cover 201, it is convenient to conduct naked-eye observation of the honeycomb carrier. When observation is required through the electron microscope body 215, the light-shielding cover 201 can be closed with the observation box 101 by engaging the hook 220 with the fixing block 102, providing a closed environment and avoiding external factors from affecting the observation of the honeycomb carrier.

[0054] Please see Figures 9-11A translation motor 204 is fixedly installed inside one side of the second sprocket limiting cover 203. The output end of the translation motor 204 is fixedly connected to the second sprocket transmission assembly 205 (as shown in the figure).

A longitudinal threaded sleeve 211 is threadedly connected to the outer side of the longitudinal threaded rod 210. A longitudinal limiting plate 212 is fixedly installed at the bottom of the longitudinal threaded sleeve 211. The longitudinal limiting plate 212 causes the longitudinal threaded sleeve 211 to move axially along the longitudinal threaded rod 210 without rotating circumferentially. A microscope probe 213 is fixedly installed at the bottom of the longitudinal limiting plate 212. A connecting wire 214 is fixedly connected to one side of the microscope probe 213. The sprocket drive assembly consists of a sprocket and a chain, thereby realizing the transmission function.

[0055] The electron microscope body 215 is fixedly mounted on the top of the light shield 201. A locking bracket 216 is symmetrically mounted on the side of the light shield 201 away from the second sprocket limiting cover 203. A locking sliding rod 217 is fixedly mounted inside the locking bracket 216. A locking sliding sleeve 218 is slidably connected to the outside of the locking sliding rod 217. A locking spring 219 is fixedly mounted at the bottom of the locking sliding sleeve 218. A locking hook 220 is rotatably connected to the outside of the locking sliding sleeve 218. The locking hook 220 is locked and connected to the fixing block 102. When the translation motor 204 is started, it drives the translation threaded rod 206 to rotate through the second sprocket transmission assembly 205, so that the translation threaded sleeve 207 and the longitudinal support 208 move horizontally. At the same time, the longitudinal motor 209 is started to drive the longitudinal threaded rod 210 to rotate, so that the longitudinal threaded sleeve 211 drives the microscope probe 213 to move longitudinally under the action of the longitudinal limiting plate 212. This enables the microscope probe 213 to move in all directions, which is convenient for the observation of the honeycomb carrier.

[0056] Working principle: Before use, the overall condition of the device needs to be checked to ensure it can operate normally. Figure 1 - Figure 11As shown, firstly, the first adjusting threaded rod 103 drives the lifting bracket 104 and the translation bracket 119 to move relative to each other inside the observation box 101, thereby adjusting the distance between the two limiting rotating plates 115, which facilitates the support of honeycomb carriers of different sizes. By rotating the lifting knob 105, the lifting threaded rod 106 is rotated, causing the lifting threaded sleeve 107 to drive the first rotating bracket 108 and the limiting support plate 114 to move up and down. Under the action of the pressing rotating rod 118, the limiting rotating plate 115 can be rotated. Under the elastic force of the pressing spring 116, the pressing block 117 presses and fixes the side of the honeycomb carrier. At the same time, the limiting rotating plate 115 rotates to a vertical state, which can expose the bottom of the honeycomb carrier and prevent the limiting rotating plate 115 from blocking the bottom of the honeycomb carrier, thereby affecting the lighting and observation of the blocked part of the honeycomb carrier.

[0057] By rotating the tilt knob 109, the first bevel gear transmission assembly 110 and the tilt threaded rod 111 are driven to rotate, causing the tilt threaded sleeve 112 to move outside the tilt threaded rod 111. At the same time, the tilt rotating rod 113 is rotated, thereby adjusting the tilt angle of the limiting support plate 114, which facilitates limiting support for honeycomb carriers of different thicknesses. By starting the support motor 122, the first sprocket transmission assembly 123 and the support rotating rod 124 are driven to rotate, causing the second bevel gear transmission assembly 125 to drive the support threaded rod 126 to rotate. Under the action of the support top plate 127, the support lifting plate 128 can move up and down outside the support threaded rod 126, which can adjust the distance between the observation lamp 143 and the honeycomb carrier, facilitating the observation of the honeycomb carrier.

[0058] Secondly, starting the first rotating motor 129 drives the rotating gear 130 to rotate. Utilizing the meshing connection between the rotating gear 130 and the meshing gear 131, the adjusting disc 132 can be rotated. Simultaneously, starting the adjusting motor 133 drives the second adjusting threaded rod 134 to rotate, causing the adjusting threaded sleeve 135 to move the observation lamp 143 under the action of the adjusting limit disc 136. This allows for adjustment of the position of the observation lamp 143, facilitating omnidirectional illumination. By starting the second rotating motor 138, the rotating worm gear 139 is driven to rotate. Utilizing the meshing connection between the rotating worm gear 139 and the rotating worm wheel 140, the rotating worm wheel 140 drives the rotating lamp holder 141 to rotate horizontally. Simultaneously, starting the third rotating motor 142 drives the observation lamp 143 to rotate vertically, allowing for adjustment of the angle of the observation lamp 143. This facilitates illumination of the honeycomb carrier from different directions, improving the observation effect.

[0059] Finally, the light shield 201 is opened or closed using the connecting hinge 202. By adjusting the angle of the light shield 201, it is convenient to observe the honeycomb carrier with the naked eye. When observation is required through the electron microscope body 215, the light shield 201 and the observation box 101 can be closed by engaging the hook 220 with the fixing block 102, providing a closed environment and avoiding external factors from affecting the observation of the honeycomb carrier. By starting the translation motor 204, the second sprocket transmission assembly 205 and the translation threaded rod 206 are rotated, causing the translation threaded sleeve 207 to drive the longitudinal support 208 to move horizontally. At the same time, the longitudinal motor 209 is started to drive the longitudinal threaded rod 210 to rotate, causing the longitudinal threaded sleeve 211 to drive the microscope probe 213 to move longitudinally under the action of the longitudinal limiting plate 212. This enables the microscope probe 213 to move in all directions, facilitating the observation of the honeycomb carrier.
