Technical Field
[0001] This utility model relates to the field of production feeding technology, specifically a coal-fired catalyst production feeding device. Background Technology
[0002] Coal combustion catalysts are a class of chemical substances used to improve combustion efficiency and reduce pollutant emissions during coal combustion. They accelerate chemical reactions through catalysis, making the coal combustion process more complete and thus reducing the generation of harmful substances. A coal combustion catalyst production device is a piece of equipment used to precisely mix different types of raw materials in a specific ratio to prepare catalysts for improving combustion efficiency and reducing pollutant emissions during coal combustion. Some existing devices are equipped with feeding devices for intermittent feeding during the coal combustion catalyst production process.
[0003] Because the pressure of the coal-fired catalyst increases during the mixing process, the feeding device components may leak gas during the coal-fired catalyst mixing process, resulting in material leakage. Therefore, a coal-fired catalyst production feeding device is proposed to address the above problems. Utility Model Content

[0023] Please see Figure 1-5 This utility model provides a technical solution:
[0024] A coal-fired catalyst production feeding device includes a control device 1, a production mixing tank 2 rotatably connected inside the control device 1, and a tank cover 3 installed at the top of the production mixing tank 2. A feeding groove 4 is vertically penetrating the center of the tank cover 3. A sealing groove 5 is provided on the outside of the feeding groove 4 at the bottom of the tank cover 3. Multiple vertically arranged limiting rods 6 are fixedly connected to the bottom of the tank cover 3 on the outside of the sealing groove 5. A baffle 7 is fixedly connected to the bottom of the limiting rod 6, and a fixing plate 8 is slidably connected to the outside of the limiting rod 6. The top of the fixing plate 8 is fixed... A sealing ring 9 is connected, and a conical block 10 is fixedly connected to the top of the fixing plate 8 inside the sealing ring 9. A fixing ring 11 is fixedly connected to the outside of the conical block 10. A limiting ring 12 is fixedly connected to the top of the box cover 3 outside the filling groove 4. A positioning component 13 is provided inside the limiting ring 12. The sealing ring 9 is located inside the sealing groove 5 and is tightly fitted to the inside of the sealing groove 5. The conical block 10 is set inside the filling groove 4. The positioning component 13 includes a hook 131 hanging inside the fixing ring 11. A vertically mounted hook 131 is rotatably connected to the top of the hook 131. The positioning bolt 132 is provided, and a threaded cylinder 133 is threadedly connected to the outside of the positioning bolt 132. A limiting cylinder 134 is fixedly connected to the bottom end of the threaded cylinder 133. Multiple horizontal observation slots 135 are provided on the outside of the limiting cylinder 134, penetrating the limiting cylinder 134. The positioning bolt 132 is located inside the limiting cylinder 134 and penetrates the limiting cylinder 134. The limiting cylinder 134 is snapped into the inside of the limiting ring 12. The bottom end of the limiting cylinder 134 is tightly fitted to the top end of the box cover 3. The filling groove 4, sealing groove 5, limiting rod 6, baffle 7, and fixing plate 8 are provided. The device consists of a sealing ring 9, a conical block 10, a fixing ring 11, a limiting ring 12, and a positioning component 13. After the material is added, install the positioning component 13, hang the hook 131 on the inside of the fixing ring 11 and pull it upward. Rotate the limiting cylinder 134 to move it to the inside of the limiting ring 12. Finally, tighten the positioning bolt 132, and the device can be used normally. When the pressure inside the device increases, the fixing plate 8 can be firmly pressed against the bottom of the box cover 3 by air pressure. The positioning component 13 and its connecting components can prevent leakage caused by excessive pressure in the production mixing box 2.
[0025] The positioning component 13 has an exhaust valve 14 fixedly connected to the top of the box cover 3 and communicating with the inside of the production mixing box 2. Below the exhaust valve 14 is a threaded ring 15 fixedly connected to the bottom of the box cover 3. A threaded cover 16 is threadedly connected to the outside of the threaded ring 15. A filter cylinder 17 is fixedly connected to the bottom of the threaded cover 16. When material needs to be added, the exhaust valve 14 is opened through the exhaust valve 14, threaded ring 15, threaded cover 16, and filter cylinder 17. At this time, the gas inside the production mixing box 2 passes through the filter cylinder 17 and is discharged from the exhaust valve 14. The solid dust inside the production mixing box 2 is blocked by the filter cylinder 17. The design of the filter cylinder 17 can prevent solid dust from entering the exhaust valve 14 and causing the exhaust valve 14 to be blocked. The design of the exhaust valve 14 can reduce the pressure inside the production mixing box 2 and prevent the fixing plate 8 from being unable to detach from the bottom of the box cover 3 due to excessive pressure.
[0026] Workflow: Before use, power on the equipment and add an appropriate amount of initial material to the production mixing tank 2. Then, install the various components on the equipment. First, install the filter cartridge 17 and screw the threaded cap 16 onto the outside of the threaded ring 15 at the bottom of the tank cover 3. Next, fix the tank cover 3 to the top of the production mixing tank 2. Then, install the positioning component 13. The operator holds the limiting cylinder 134 and rotates the positioning bolt 132 inside the threaded cylinder 133 until the hook 131 at the bottom of the positioning bolt 132 is completely disengaged from the limiting cylinder 134. Next, hook the hook 131 onto the inside of the fixing ring 11 on the conical block 10 and pull it upwards so that the fixing plate 8 is outside the limiting rod 6. Slide the cone block 10 until it moves to the inside of the feeding trough 4 and the sealing ring 9 moves to the inside of the sealing groove 5. Next, rotate the limiting cylinder 134 until it moves to the inside of the limiting ring 12 on the box cover 3. Finally, tighten the positioning bolt 132 inside the threaded cylinder 133 until the bottom of the limiting cylinder 134 is tightly fitted with the top of the box cover 3 and the outer side of the sealing ring 9 is tightly fitted with the inner side of the sealing groove 5. This completes the installation of the positioning component 13, and the device can be used normally. The operator can start the control device 1 to make the production mixing box 2 rotate continuously for preliminary mixing. When the pressure inside the device increases, the pressure difference between the inside and outside of the production mixing box 2 is large. The fixing plate 8 can be firmly pressed against the bottom of the box cover 3 by air pressure. The positioning component 13 and its connecting components can prevent leakage caused by excessive pressure in the production mixing box 2. When it is necessary to add material, the operation control device 1 stops the rotation of the production mixing box 2, and then opens the exhaust valve 14. At this time, the gas inside the production mixing box 2 passes through the filter cylinder 17 and is discharged from the exhaust valve 14. The solid dust inside the production mixing box 2 is blocked by the filter cylinder 17. The design of the filter cylinder 17 can prevent solid dust from entering the exhaust valve 14 and causing the exhaust valve 14 to become blocked. Next, rotate the positioning bolt 132 to make the limiting cylinder 134 slightly disengage from the top of the box cover 3, and then rotate. The limiting cylinder 134 completely disengages the hook 131 from the limiting cylinder 134. At this time, the position of the hook 131 and the fixing ring 11 can be observed through the observation groove 135. The limiting cylinder 134 is tilted to remove the hook 131. Finally, the cone block 10 is pressed down to disengage the sealing ring 9 from the sealing groove 5, and the fixing plate 8 slides outside the limiting rod 6 until it moves to the top of the baffle 7. At this time, materials can be added to the inside of the production mixing box 2 through the feeding groove 4. The design of the exhaust valve 14 can reduce the pressure inside the production mixing box 2 and prevent the fixing plate 8 from failing to disengage from the bottom of the box cover 3 due to excessive pressure. After the feeding is completed, the device can be restored to continue stirring and mixing the materials.
