Description

Technical Field

[0001] The invention relates to the technical field of ozone catalyst production, and in particular to an ozone catalyst preparation device. Background Art

[0002] An ozone catalyst is a catalyst used to improve the efficiency of ozone oxidation. Ozone catalytic oxidation technology combines the strong oxidizing properties of ozone with the adsorption and catalytic properties of the catalyst, and can more effectively solve the problem of incomplete degradation of organic matter. According to the form, ozone catalysts can be divided into two categories: homogeneous catalysts and heterogeneous catalysts. Homogeneous catalysts utilize the catalytic effect of metal ions in solution, while heterogeneous catalysts use solid metals, metal oxides, or metals or metal oxides loaded on a carrier. Common ozone catalysts on the market are divided into expanded clay, activated carbon, silicon-aluminum composite materials, and activated alumina according to the different carriers. The activated alumina matrix is ​​chemically bonded to the catalytic component, has a long life and strong anti-pollution ability. When preparing ozone catalysts, the ozone catalysts are often made into spherical shapes for subsequent use.

[0003] A Chinese patent document with announcement number CN219334107U discloses a pelletizing machine production line for an ozone catalyst, including a base and a steel frame platform, a pelletizing machine is arranged on the rear side of the base, a raw material bin is arranged above the pelletizing machine, the raw material bin runs through the steel frame platform, a screw feeder is installed at the lower end of the raw material bin, the outlet end of the screw feeder extends to the inside of the pelletizing machine, a feeder pit is opened at the right end of the base, a feeder is arranged in the feeder pit, a mixer is arranged below the output port of the feeder, an elevator pit is arranged below the discharge pipe on one side of the mixer, a bucket elevator extending vertically upward is arranged in the elevator pit, a spiral distributor is connected to one side of the upper end of the bucket elevator, and a number of pneumatic valves are evenly arranged on the spiral distributor.

[0004] However, the above patent still has the following shortcomings: when the screw feeder conveys the raw materials into the ball forming machine, the distance between the discharge end of the screw feeder and the feed port of the ball forming machine is relatively close. When water and adhesive are subsequently conveyed from the feed port of the ball forming machine into the ball forming machine, the air moisture content at the feed port of the ball forming machine is relatively high, which can easily cause the discharge end of the screw feeder to become wet and adhere to the raw materials to block the discharge end, thereby affecting the feeding of the screw feeder. Summary of the invention

[0005] The present invention provides an ozone catalyst preparation device, which aims to solve the problem in the related art that when water and adhesive are subsequently transported from the feed port of the ball forming machine into the ball forming machine, the air at the feed port of the ball forming machine has a high water content, which easily causes the discharge end of the screw feeder to become wet and adhere to raw materials, thereby blocking the discharge end and affecting the feeding of the screw feeder.

[0006] The ozone catalyst preparation device of the present invention includes a feeding mechanism, which has a discharge end, and also includes a mounting pipe and a discharge piece. The mounting pipe is connected to the discharge end, and the discharge piece includes six groups of transmission structures, six shielding belts and six universal joint couplings. The six groups of transmission structures are all connected in the mounting pipe, and the six shielding belts are respectively connected to the six groups of transmission structures in a transmission manner. The six shielding belts can form a discharge channel, and the bottom end of the discharge end is inserted in the discharge channel. The six universal joint couplings can be connected between the six groups of transmission structures so that the six groups of transmission structures can run synchronously, thereby driving the six shielding belts to run synchronously.

[0007] Beneficial effect: After the feeding mechanism conveys the raw materials to the discharge channel, six sets of transmission structures and six universal joint couplings drive the six shielding belts to run synchronously, which can make the position of the inner wall of the discharge channel constantly change, so as to avoid the end of the discharge channel close to the ball forming machine being soaked by humid air for a long time, causing the raw materials to adhere to and clog the end of the discharge channel, thereby avoiding the discharge channel after the raw materials adhere to the feeding of the screw feeder.

[0008] Preferably, the transmission structure includes frame 1, frame 2, active roller and driven roller, frame 1 and frame 2 are both connected in the installation pipe, the active roller is rotatably connected in frame 1, the driven roller is rotatably connected in frame 2, and the six shielding belts are respectively connected between the active rollers and the driven rollers on the six groups of transmission structures. The effect is that the active roller can rotate, thereby driving the transmission between the active roller, the driven roller and the shielding belt.

[0009] Preferably, the six shielding strips are all in arc shape, and the inner diameter of the discharge channel is larger than the outer diameter of the discharge end. The effect is that the discharge channel can be formed by the six arc-shaped shielding strips, and the inner wall of the discharge channel does not contact the discharge end to avoid affecting the normal operation of the shielding strips.

[0010] Preferably, the universal joint coupling is connected to the driven rollers on two adjacent transmission structures, so that the driven rollers on the six transmission structures can rotate synchronously. The effect is that the driven rollers on the six transmission structures rotate synchronously, which can drive the six shielding belts to run synchronously, so that the inner wall position of the discharge channel can be continuously changed.

[0011] Preferably, it also includes a cleaning mechanism for cleaning the raw materials attached to the shielding belt.

[0012] Preferably, the cleaning mechanism includes cleaning parts and driving parts. The cleaning parts are arranged in six groups. The six groups of cleaning parts are all connected to the bottom end of the installation pipe, and the six groups of cleaning parts can clean the raw materials attached to the six shielding belts respectively. The driving part is connected to the installation pipe and the six groups of cleaning parts, and the driving part can drive the six groups of cleaning parts one by one.

[0013] Preferably, the cleaning member includes a scraper, a connecting portion, a containing portion, a pushing portion and an elastic portion 1, the scraper is connected to the inner lower end of the installation pipe, the top of the scraper contacts the bottom of the shielding belt, the connecting portion is connected between the scraper and the containing portion, the pushing portion is rotatably connected to the bottom of the scraper, the bottom of the pushing portion is inserted in the containing portion, and the elastic portion 1 is connected between the pushing portion and the scraper. The effect is that the cleaned raw materials slide from the scraper and the pushing portion into the containing portion, so that the raw materials gradually accumulate in the containing portion, when the driving member passes through the group of cleaning members, the pushing portion is pushed to rotate, and the pushing portion pushes out the raw materials in the containing portion, so that the raw materials fall into the ball forming machine, because the accumulated raw materials in the containing portion gather together and contain moisture, the weight of the raw materials themselves can be increased, so as to avoid the raw materials from being unable to accurately fall into the ball forming machine due to the influence of the surrounding wind after leaving the containing portion.

[0014] Preferably, the driving member includes a gear ring, a second driving source, a gear, a guide portion, a movable portion and a second elastic portion, the gear ring is rotatably connected to the bottom end of the mounting pipe, the second driving source is connected to the outer lower end of the mounting pipe, the gear is connected to the output shaft of the second driving source, the gear and the gear ring are meshed and connected, the guide portion is connected to the inner side of the gear ring, the movable portion and the second elastic portion are each set to six, the six movable portions are respectively inserted into the connecting portions in the six groups of cleaning members, and the six elastic portions are respectively connected between the six movable portions and the six connecting portions.

[0015] The beneficial effects of the present invention are: 1. After the feeding mechanism transports the raw materials to the discharge channel, six sets of transmission structures and six universal joint couplings drive six shielding belts to run synchronously, which can make the position of the inner wall of the discharge channel constantly change, so as to avoid the end of the discharge channel close to the ball forming machine being soaked by humid air for a long time, causing the raw materials to adhere to the end of the discharge channel, thereby avoiding the discharge channel adhering to the raw materials and affecting the feeding of the screw feeder.

[0016] 2. The cleaned raw materials slide from the scraper and the pushing part to the containing part, so that the raw materials are gradually accumulated in the containing part. When the driving part passes through this group of cleaning parts, it pushes the pushing part to rotate, and the pushing part pushes the raw materials in the containing part out, so that the raw materials fall into the ball forming machine. Because the raw materials accumulated in the containing part gather together and contain moisture, the weight of the raw materials themselves can be increased, so as to avoid the raw materials from being unable to fall accurately into the ball forming machine due to the influence of the surrounding wind after leaving the containing part.

[0027] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] like Figures 1 to 9As shown, the ozone catalyst preparation device of the present invention includes a feeding mechanism 1, a discharging mechanism 2 and a cleaning mechanism 3. The feeding mechanism 1 is connected to the bottom of the raw material bin (the raw material bin is the prior art, not shown in the figure), and is used to transport the raw materials in the raw material bin to the discharging mechanism 2. The discharging mechanism 2 is connected to the feeding mechanism 1. A discharging channel 24 is arranged in the discharging mechanism 2. The discharging channel 24 is used to guide and transport the raw materials, so as to transport the raw materials to a pelletizing machine (the pelletizing machine is the prior art, not shown in the figure), and the position of the inner wall of the discharging channel 24 can be continuously changed to avoid the end of the discharging channel 24 close to the pelletizing machine from being soaked by humid air for a long time, so as to cause the raw materials to adhere to and clog the end of the discharging channel 24. The cleaning mechanism 3 is connected to the discharging mechanism 2, and is used to clean the raw materials on the inner wall of the discharging channel 24.

[0029] like Figure 1 and Figure 2 As shown, the feeding mechanism 1 includes a feeding channel 11, a feeding end 12, a discharging end 13 and a feeding piece 14. The feeding end 12 is connected to the top left end of the feeding channel 11, and the feeding end 12 can be connected to the bottom of the raw material bin, so that the raw materials in the raw material bin enter the feeding channel 11 from the feeding end 12. The discharging end 13 is connected to the bottom right end of the feeding channel 11, and is used to transport the raw materials to the discharging mechanism 2. The feeding piece 14 is connected in the feeding channel 11. The feeding piece 14 includes a motor, a drive shaft and an auger blade. The drive shaft is rotatably connected in the feeding channel 11, and the auger blade is connected to the outside of the drive shaft. The motor is connected to the left end of the feeding channel 11, and the output shaft of the motor is connected to the drive shaft. Starting the motor can drive the drive shaft and the auger blade to rotate, thereby transporting the raw materials.

[0030] The raw materials in the raw material bin enter the feeding channel 11 from the feeding end 12, and the motor is started to drive the drive shaft and the auger blades to rotate, and the raw materials are transported to the discharging end 13 through the auger blades, so that the raw materials are transported from the discharging end 13 to the discharging mechanism 2.

[0031] like Figure 1 , Figures 3 to 5 As shown, the discharging mechanism 2 includes a mounting pipe 21, a discharging piece 22 and a driving source 23. The mounting pipe 21 is connected to the discharging end 13, and the discharging piece 22 is connected in the mounting pipe 21. The discharging piece 22 can form a discharging channel 24, through which the raw materials entering the discharging mechanism 2 are guided so that the raw materials enter the ball forming machine. The driving source 23 is connected to the discharging piece 22, and is used to drive the discharging piece 22 to operate so that the position of the inner wall of the discharging channel 24 changes continuously, so as to avoid the end of the discharging channel 24 close to the ball forming machine from being soaked by humid air for a long time, causing the raw materials to adhere to the end of the discharging channel 24.

[0032] refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, the discharging member 22 includes six groups of transmission structures, six shielding belts 225 and six universal joint couplings 226. The transmission structure includes a frame 1 221, a frame 222, an active roller 223 and a driven roller 224. The frame 1 221 and the frame 222 are both connected in the installation pipe 21. The frame 1 221 is located directly above the frame 222. The active roller 223 is rotatably connected in the frame 1 221, and the driven roller 224 is rotatably connected in the frame 222. The six shielding belts 225 are respectively transmission-connected between the active rollers 223 and the driven rollers 224 on the six groups of transmission structures, and the six shielding belts 225 are all in an arc shape, so that the six shielding belts 225 form a discharging channel 24, and the inner diameter of the discharging channel 24 is large. At the outer diameter of the discharge end 13, the bottom end of the discharge end 13 is inserted into the discharge channel 24, and the universal joint coupling 226 is connected to the driven rollers 224 on the two adjacent groups of transmission structures, so that the driven rollers 224 on the six groups of transmission structures can rotate synchronously, thereby driving the six shielding belts 225 to run synchronously, and then the inner wall position of the discharge channel 24 can be continuously changed, so as to avoid the end of the discharge channel 24 close to the ball forming machine from being soaked by humid air for a long time, causing the raw materials to adhere to and clog the end of the discharge channel 24. The driving source 23 is a motor, and the driving source 23 is connected to the frame 221 in one of the groups of transmission structures, and the output shaft of the driving source 23 is connected to the active roller 223 in the group of transmission structures.

[0033] Six shielding belts 225 form a discharge channel 24. The raw materials discharged from the discharge end 13 enter the discharge channel 24, and are guided and transported into the ball forming machine by the discharge channel 24. The driving source 23 is started to drive one group of transmission structures and the shielding belts 225 on the group to transmit. At this time, the remaining five groups of transmission structures and the five shielding belts 225 are driven to run synchronously through the six universal joint couplings 226, so that the six shielding belts 225 run synchronously, thereby causing the inner wall position of the discharge channel 24 to change continuously.

[0034] like Figure 1 , Figures 6 to 9 As shown, the cleaning mechanism 3 includes cleaning pieces 31 and driving pieces 32. The cleaning pieces 31 are arranged in six groups. The six groups of cleaning pieces 31 are all connected to the bottom end of the installation pipe 21, and the six groups of cleaning pieces 31 can clean the raw materials attached to the six shielding belts 225 respectively. The driving piece 32 is connected to the installation pipe 21 and the six groups of cleaning pieces 31, and the driving piece 32 can drive the six groups of cleaning pieces 31 one by one.

[0035] Continue to refer Figure 1 , Figures 6 to 9As shown, the cleaning member 31 includes a scraper 311, a connecting portion 312, a containing portion 313, a pushing portion 314 and an elastic portion 315. The scraper 311 is connected to the inner lower end of the mounting pipe 21. The top of the scraper 311 contacts the bottom of the shielding belt 225, and is used to clean the raw materials attached to the shielding belt 225. The containing portion 313 is located below the scraper 311. The connecting portion 312 is connected between the scraper 311 and the containing portion 313, and is used to support the containing portion 313. The containing portion 313 is used to contain the cleaned raw materials. The pushing portion 314 is rotatably connected to the bottom of the scraper 311, and the bottom of the pushing portion 314 is inserted in the containing portion 313. The elastic portion 315 is connected between the pushing portion 314 and the scraper 311. The elastic portion 315 is a torsion spring, and is used to drive the pushing portion 314 to reset.

[0036] The cleaned raw materials slide from the scraper 311 and the pushing part 314 into the containing part 313, so that the raw materials are gradually accumulated in the containing part 313. When the driving part 32 passes through the group of cleaning parts 31, it pushes the pushing part 314 to rotate, and the pushing part 314 pushes out the raw materials in the containing part 313, so that the raw materials fall into the ball forming machine. Because the raw materials accumulated in the containing part 313 are gathered together and contain moisture, the weight of the raw materials themselves can be increased, so as to avoid the raw materials from being unable to accurately fall into the ball forming machine due to the influence of the surrounding wind after leaving the containing part 313.

[0037] Continue to refer Figure 1 , Figures 6 to 9 As shown, the driving member 32 includes a gear ring 321, a second driving source 322, a gear 323, a guide portion 324, a movable portion 325 and a second elastic portion 326. The gear ring 321 is rotatably connected to the bottom end of the installation pipe 21, the second driving source 322 is connected to the lower end of the outer side of the installation pipe 21, the second driving source 322 is a motor, the gear 323 is connected to the output shaft of the second driving source 322, the gear 323 and the gear ring 321 are meshed and connected, and the guide portion 324 is connected to the inner side of the gear ring 321. On the side, the guide part 324 is inclined, and the movable part 325 and the elastic part 326 are each set to six. The six movable parts 325 are respectively inserted into the connecting parts 312 in the six groups of cleaning parts 31, and the six elastic parts 315 are respectively connected between the six movable parts 325 and the six connecting parts 312. The elastic part 315 is a spring for driving the movable part 325 to reset. The movable part 325 can push the pushing part 314 to rotate, thereby pushing out the raw materials accumulated in the containing part 313.

[0038] The driving source 2 322 is started to drive the gear 323 and the gear ring 321 to engage and transmit, so as to drive the guide part 324 to move along a circular trajectory. When the guide part 324 passes through the movable part 325, it can push the movable part 325 away from the pushing part 314 and stretch the elastic part 1 315. After the movable part 325 is separated from the guide part 324, the elastic force of the elastic part 1 315 drives the movable part 325 to quickly reset and push the pushing part 314 to rotate, so that the pushing part 314 can push out the raw materials accumulated in the containing part 313.

[0039] Working principle: The raw materials in the raw material bin enter the feed channel 11 from the feed end 12 , and the motor is started to drive the drive shaft and the auger blades to rotate, and the raw materials are transported to the discharge end 13 through the auger blades, so that the raw materials are transported from the discharge end 13 to the discharge channel 24 .

[0040] Start the driving source 23 to drive one of the transmission structures and the shielding belt 225 on the group. At this time, the remaining five transmission structures and the five shielding belts 225 are driven to run synchronously through six universal joint couplings 226, so that the six shielding belts 225 run synchronously, thereby changing the inner wall position of the discharge channel 24 continuously.

[0041] Start the driving source 2 322 to drive the gear 323 and the gear ring 321 to engage and transmit, so as to drive the guide part 324 to move along a circular trajectory. When the guide part 324 passes through the movable part 325, it can push the movable part 325 away from the pushing part 314 and stretch the elastic part 1 315. After the movable part 325 is separated from the guide part 324, the elastic force of the elastic part 1 315 drives the movable part 325 to quickly reset, and pushes the pushing part 314 to rotate, so that the pushing part 314 pushes out the raw materials accumulated in the containing part 313, and the pushed out raw materials fall into the ball forming machine.
