Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical technology, specifically to an activated mesh belt cleaning device. Background Technology
[0002] The production process of solid catalysts typically includes steps such as carrier impregnation, solid-liquid separation, and carrier activation. After solid-liquid separation, some impregnation liquid remains on the surface of the carrier. At this point, the activation mesh belt 201 of the conveyor 2 carries these carriers into the activation furnace 1 for activation. However, under the high-temperature activation environment of the activation furnace, the residual impregnation liquid decomposes and precipitates substances. These substances easily crystallize on the surface of the activation mesh belt 201 of the conveyor and form agglomerates. These agglomerates gradually clog the pores of the mesh belt, causing a decrease in the permeability of the activation mesh belt 201, thereby affecting the activation efficiency and product quality.
[0003] Currently, the main solution to the problem of conveyor belt blockage is to replace the blocked activated conveyor belt 201 and clean the agglomerates by acid washing or high-temperature heating. However, the activated conveyor belt 201 is usually made of steel, is quite long, and can weigh hundreds of kilograms when covered with agglomerates. Furthermore, replacement requires connecting the old and new conveyor belts and manually dragging them, which is time-consuming, labor-intensive, and requires multiple people to work together. Utility Model Content
[0004] The purpose of this utility model is to overcome the aforementioned technical problems existing in the prior art.
[0005] To achieve the above objectives, this utility model provides an activated conveyor belt cleaning device, comprising: The fixing part is used to connect to the frame of the transmission machine; The scraper is mounted on the fixed part and located below the return section of the activated mesh belt of the conveyor. The blade of the scraper abuts against the bearing surface of the activated mesh belt to scrape off dirt from the activated mesh belt.
[0006] Optionally, the activated mesh belt cleaning device also includes a limiting member disposed on the frame, which is used to restrict the activated mesh belt from moving away from the blade.
[0007] Optionally, the limiting component includes a limiting wheel, which is rotatably connected to the frame and located above the scraper. The blade of the scraper and the limiting wheel are respectively positioned to abut against the two sides of the activated mesh belt.
[0008] Optionally, the fixing part includes a fixing plate and an adjusting assembly. The fixing plate is connected to the frame, and the adjusting assembly is used to connect the scraper to the fixing plate and to adjust the scraper to move closer to or further away from the activated mesh belt.
[0009] Optionally, the adjusting assembly includes bolts and a connecting plate. The bolts are mounted on the fixed plate, and adjusting nuts and fastening nuts are spaced apart on the bolts. The connecting plate is movably sleeved on the bolts and located between the adjusting nuts and fastening nuts. A scraper is mounted on the side surface of the connecting plate facing the activated mesh belt.
[0010] Optionally, washers are provided between the adjusting nut and the fastening nut and the connecting plate.
[0011] Optionally, the scraper and the connecting plate are set at an angle.

[0018] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0019] In this utility model, reference Figure 1 High-temperature activation equipment for activating solid catalysts generally includes an activation furnace 1 and a conveyor 2. The conveyor 2 includes two frames 202 respectively set at the inlet and outlet of the activation furnace 1. The two frames 202 are respectively equipped with a drive wheel 203 and a driven wheel 204, and an activation mesh belt 201 is wound on the drive wheel 203 and the driven wheel 204.
[0020] The path taken by the activation mesh belt 201 carrying the solid catalyst through the activation furnace 1 is the process segment; the path taken by the activation mesh belt 201 from the outside of the activation furnace 1 at the position of the driven wheel 204 back to the position of the driving wheel 203 is the return segment.
[0021] refer to Figure 2 The activated mesh belt cleaning device of this utility model includes: Fixing part 3, which is used to connect to the frame 202 of the transmission machine 2; Scraper 4 is provided on the fixing part 3 and located below the return section of the activated mesh belt 201 of the conveyor 2. The blade 401 of the scraper 4 abuts against the bearing surface of the activated mesh belt 201 and is used to scrape off dirt on the activated mesh belt 201.
[0022] Since the scraper 4 is connected to the frame 202 through the fixing part 3, the scraper 4 can be in a relatively stationary state with the frame 202.
[0023] During the movement of the activated mesh belt 201 relative to the frame 202, the blade 401 of the scraper 4 can contact the dirt on the bearing surface of the activated mesh belt 201 and apply a scraping force opposite to the moving direction of the activated mesh belt 201.
[0024] Understandably, when the applied scraping force is greater than the adhesive force between the dirt and the activated mesh belt 201, the blade 401 of the scraper 4 can scrape the dirt off the activated mesh belt 201.
[0025] Therefore, during the operation of the conveyor 2, the dirt generated by the activated mesh belt 201 in the process section can be scraped off by the scraper 4 on the return section, so as to achieve real-time cleaning of the dirt, thereby delaying the time for the dirt to completely block the vent holes, extending the service life of the single activated mesh belt 201, and reducing its replacement frequency.
[0026] In some embodiments, the length of the scraper 4 is longer than the width of the activated mesh belt 201, for example, it can be 10-20 mm, preferably 12 mm, so as to ensure that after the activated mesh belt 201 is laterally offset along the length direction of the scraper 4, the scraper 4 can still scrape off the agglomerates on the mesh belt.
[0027] In this utility model, since the activated mesh belt 201 has a certain toughness, the activated mesh belt 201 will deform to a certain extent when it touches the scraper 4, which will cause the bearing surface of the activated mesh belt 201 to move away from the scraper 4, making the scraper 4 unable to effectively scrape off the dirt on the bearing surface.
[0028] Therefore, in some embodiments, the activated mesh belt cleaning device may also include a limiting member 6 disposed on the frame 202, which is used to restrict the activated mesh belt 201 from moving away from the blade 401.
[0029] In this utility model, the limiting member 6 can have any suitable structure, as shown in the reference. Figure 2 In the embodiment shown, the limiting member 6 includes a limiting wheel 601, which is disposed above the scraper 4. The blade 401 of the scraper 4 and the limiting wheel 601 are respectively positioned to abut against the two side surfaces of the activated mesh belt 201.
[0030] Among them, reference Figure 1 The limiting wheel 601 presses down on the activated mesh belt 201 to reduce the height of its return section, so that the bearing surface of the return section can contact the blade 401 of the scraper 4; at the same time, it increases the tension of the activated mesh belt 201, limiting the activated mesh belt 201 from undergoing large deformation after encountering the blade 401 of the scraper 4.
[0031] Meanwhile, the scraper 4 can be positioned directly below the limiting wheel 601. It is understood that the blade 401 of the scraper 4 and the lowest point of the outer end surface of the limiting wheel 601 form a gap that allows the activated mesh belt 201 to pass through, and the size of this gap remains constant. When the activated mesh belt 201 passes through this gap, the outer end surface of the limiting wheel 601 abuts against the activated mesh belt 201 from the side opposite to the bearing surface, thereby restricting its movement away from the blade 401, allowing the blade 401 to effectively scrape away dirt from the bearing surface.
[0032] In this invention, limiting wheels 601 can be installed on both frames 202 to better maintain the tension of the activated mesh belt 201. Additionally, scrapers 4 can be installed below each limiting wheel 601 to improve the working efficiency of the device.
[0033] In some embodiments, reference Figure 4The blade 401 of the scraper 4 can be set to be serrated to adapt to the irregular surface of the activated mesh belt 201. At the same time, the tip of the serration is set to be flat to avoid scratching the activated mesh belt 201.
[0034] The interval between adjacent saw teeth is zero, so that more saw teeth can be set on the blade 401 with the limited length of the scraper 4, thereby avoiding the occurrence of large gaps after one or more saw teeth are damaged, which would prevent the dirt on the activated mesh belt 201 from being scraped off.
[0035] The scraper 4 can be made of alloy steel to extend its service life. Furthermore, if the blade 401 of the scraper 4 wears down during use, the teeth of the scraper 4 can be directly re-sharpened.
[0036] In this utility model, the frame 202 includes a top plate and columns connected to the four corners of the top plate. A crossbar 205 is provided between adjacent columns along the moving direction of the activated mesh belt 201.
[0037] In some embodiments, reference Figure 3 The fixing part 3 includes a fixing plate 301 and an adjustment component. The fixing plate 301 is connected to the frame 202. The adjustment component is used to connect the scraper 4 to the fixing plate 301 and to adjust the scraper 4 to move closer to or further away from the activation mesh belt 201, so as to adjust the relative distance between the blade 401 of the scraper 4 and the bearing surface of the activation mesh belt 201, so as to avoid the blade 401 being too far away from the bearing surface, resulting in poor scraping effect on dirt, or too close, causing the blade 401 to be deformed by the pressure of the activation mesh belt 201.
[0038] The two ends of the fixing plate 301 are fixed to the two crossbars 205 of the frame 202.
[0039] In some embodiments, the adjusting assembly includes a bolt 302 and a connecting plate 303. The bolt 302 is disposed on a fixed plate 301. An adjusting nut 304 and a fastening nut 305 are spaced apart on the bolt 302. The connecting plate 303 is movably sleeved on the bolt 302 and located between the adjusting nut 304 and the fastening nut 305. A scraper 4 is disposed on the connecting plate 303.
[0040] The adjusting nut 304 is located below the connecting plate 303. The operator can rotate the adjusting nut 304 to move it on the bolt 302, thereby adjusting the distance between the connecting plate 303 and the activated mesh belt 201. This allows the scraper 4 connected to the connecting plate 303 to move closer to or further away from the activated mesh belt 201. The fixing nut can be screwed in from the end of the bolt 302, clamping the connecting plate 303 between the adjusting nut 304 and the fastening nut 305.
[0041] In some embodiments, washers 307 are provided between the adjusting nut 304 and the fixing nut and the connecting plate 303 to limit the rotation of the adjusting nut 304 and the fixing nut relative to the bolt 302, so as to prevent the scraper 4 from becoming loose during the operation of the device, resulting in an unsatisfactory scraping effect.
[0042] In some embodiments, bolts 302 may be disposed at any position on the surface of the fixing plate 301 facing the activated mesh belt 201, and multiple bolts 302 may be disposed to improve the stability of the connection between the connecting plate 303 and the fixing plate 301.
[0043] Two sets of bolts 302 can be installed on the fixing plate 301. The two sets of bolts 302 are respectively installed on the upper surface of the fixing plate 301 (the side surface facing the limit wheel 601) and close to the two crossbars 205. The two ends of the connecting plate 303 are respectively sleeved on the two sets of bolts 302 to improve the stability of the connection between it and the fixing plate 301.
[0044] Each group of 302 bolts can be set to 2-3, preferably 2.
[0045] In some other embodiments, the adjusting nut 304 and the fastening nut 305 on each bolt 302 can clamp the edges at both ends of the connecting plate 303, thereby fixing the connecting plate 303 to the fixing plate 301. It is worth noting that this arrangement does not require the connecting plate 303 to be fitted onto the bolt 302.
[0046] In some embodiments, the scraper 4 is inclinedly disposed on the connecting plate 303 so that the scraper 4 can be set at an obtuse angle with the moving direction of the return section of the activated mesh belt 201. This allows the scraper 4 to better adapt to the running direction of the mesh belt, reducing wear on the activated mesh belt 201 while scraping off dirt. At the same time, it concentrates most of the scraped dirt on the side of the scraper 4 facing the activated mesh belt 201, facilitating subsequent collection and processing and preventing dirt from scattering randomly.
[0047] The scraper 4 moves at an angle of 90° to 120° to the return section of the activated mesh belt 201, preferably 110°.
[0048] In some embodiments, reference Figure 2 and Figure 3 The scraper 4 can be attached to the surface of the connecting plate 303 facing the activated mesh belt 201, and is located on the side of this surface near the column of the fixed limit wheel 601. This arrangement is intended to prevent dirt from accumulating on the connecting plate 303 when it slides down the surface of the scraper 4 facing the activated mesh belt 201, thereby facilitating the operator to clean the relevant parts and improving the ease of equipment maintenance.
[0049] In some embodiments, reference Figure 5The connecting plate 303 has a sloping surface 308 extending downward in a direction away from the scraper 4 on the side facing the activated mesh belt 201, which is used to drain dirt that falls on the connecting plate 303.
[0050] Among them, reference Figure 5 and Figure 6 The connecting plate 303 has two rectangular blocks 309 at both ends. Each rectangular block 309 has multiple through holes 306 for bolts 302 to pass through. The size of each through hole 306 is 14-20mm, preferably 16mm. An inclined surface 308 is provided between the two rectangular blocks 309.
[0051] The inclined surface 308 is configured to slope downward from the connection point between the scraper 4 and the connecting plate 303 in a direction away from the scraper 4.
[0052] In some embodiments, the activated mesh belt cleaning device further includes a collection element 5 for collecting the dirt scraped off by the scraper 4.
[0053] In some embodiments, the collector 5 includes a collection box 501 disposed below the scraper 4 and on the plane of the support frame 202.
[0054] Of course, in some other embodiments, the collection box 501 may be fixed to the frame 202. This will not be elaborated upon further here.
[0055] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. To avoid unnecessary repetition, the present invention will not describe various possible combinations separately. However, these simple variations and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
