Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, in particular to a reaction kettle for preparing zinc oxide. Background Art

[0002] Zinc oxide is an inorganic compound widely used in the chemical, pharmaceutical, electronics, and materials industries. The reactor is a key piece of equipment in the industrial production of zinc oxide. The type and material of the reactor used vary depending on the zinc oxide production process.

[0003] In the reactor, if there is no efficient slag discharge design, waste slag will gradually accumulate at the bottom of the reactor, resulting in a reduction in the effective reaction volume and a reduction in the contact area between the raw materials and the gas, thereby affecting the reaction rate and oxidation efficiency.

[0004] Secondly, when discharging slag, if the reactor chassis is not dust-proof, a large amount of dust will be easily generated when the waste slag is discharged. This dust will not only pollute the workshop environment, but also may cause harm to the health of operators (such as pneumoconiosis, respiratory diseases, etc.).

[0005] Finally, when there is no stirring device, the raw materials in the reactor cannot be evenly distributed, and local overheating or overcooling is likely to occur during combustion, which causes the fuel or reducing agent to fail to react fully, thereby reducing heat utilization and reaction efficiency.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1:

[0030] See also Figure 1-Figure 5, a reactor for preparing zinc oxide, comprising a main body 1, a slag discharge mechanism and an operating mechanism, the slag discharge mechanism comprising a chassis 2, a sliding plate 3, a slag discharge plate 4, a connecting bolt 5 and a dust-proof mechanism, the chassis 2 is fixedly mounted inside the main body 1, the sliding plate 3 is mounted in the chassis 2 and is slidably connected to the chassis 2, the slag discharge plate 4 is mounted on the sliding plate 3 and is rotatably connected to the sliding plate 3, the connecting bolt 5 is mounted on the sliding plate 3 and is rotatably connected to the sliding plate 3, the dust-proof mechanism comprises a closing plate 6, a connecting rod 7, a spring 8 and a bayonet 9, the closing plate 6 is mounted on the chassis 2 and is rotatably connected to the chassis 2, one end of the connecting rod 7 is slidably connected to the closing plate 6, and the other end is rotatably connected to the chassis 2, the two ends of the spring 8 are fixedly connected to the bayonet 9 and the connecting rod 7 respectively, and the bayonet 9 is mounted on the connecting rod 7 and is slidably connected to the connecting rod 7.

[0031] In this embodiment, the slag discharge mechanism includes a chassis 2, a sliding plate 3, a slag discharge plate 4, a connecting bolt 5 and a dustproof mechanism. When in use, the dustproof mechanism is opened, and then an external rod is connected to the connecting bolt 5, and then the connecting bolt 5 is pushed, so that the sliding plate 3 slides in the first chute 15, and when the slag discharge plate 4 contacts the waste slag in the chassis 2, the slag discharge plate 4 will rotate under the force. When the sliding plate 3 is pulled again, the stop plate 18 on the slag discharge plate 4 contacts and is fixed with the sliding plate 3, and as the sliding plate 3 slides, the waste slag is pulled out of the chassis 2 and discharged at the slag discharge port 16. The waste slag that accidentally falls into the first chute 15 will also be pushed into the slag flow port 17 as the sliding plate 3 slides, and then discharged from the chassis 2.

[0032] In this embodiment, the dust-proof mechanism includes a closing plate 6, a connecting rod 7, a spring 8 and a latch 9. When in use, the latch 9 is first pulled. At this time, the latch 9 compresses the spring 8 installed in the placement groove 21, so that the latch 9 disengages from the latch hole 22 on the chassis 2. At this time, the closing plate 6 is pulled, and the connecting block 20 at one end of the connecting rod 7 slides in the second slide groove 19. When the closing plate 6 is fully opened, the latch 9 is released, and the compressed spring 8 pushes the latch 9 into the latch hole 22 of the chassis 2, thereby fixing the closing plate 6.

[0033] In this embodiment, the operating mechanism includes an operating motor 10, an exhaust pipe 11, a control valve 12, a liner 13 and a flame ring 14. When in use, materials are fed into the feed port 27 on the main body 1, and the materials enter the combustion chamber 23 of the liner 13. At this time, the flame ring 14 starts to run and burns the materials in the combustion chamber 23. As the materials burn, the operating motor 10 starts to run and drives the rotating rod 25 to rotate. Driven by the rotating rod 25, all the materials are pushed by the rotating rod 25 and roll in the combustion chamber 23. The waste materials will fall to the bottom of the combustion chamber 23 under the influence of gravity, and will be pushed to the discharge port 24 by the rotating rod 25, and then fall onto the chassis 2. The remaining materials continue to burn, and the steam generated during the combustion of the materials will enter the exhaust pipe 11 through the gas collecting hopper 26, and then the control valve 12 will open and enter the condensation system to be collected.

[0034] Example 2:

[0035] To sum up, when in use, materials are fed into the feed port 27 on the main body 1, and the materials enter the combustion chamber 23 of the lining 13. At this time, the flame ring 14 starts to run and burns the materials in the combustion chamber 23. As the materials burn, the running motor 10 starts to run and drives the rotating rod 25 to rotate. Driven by the rotating rod 25, all the materials are pushed by the rotating rod 25 and roll in the combustion chamber 23. The waste materials will fall to the bottom of the combustion chamber 23 under the influence of gravity and be pushed to the discharge port 24 by the rotating rod 25, and then fall onto the chassis 2. The rest of the materials continue to burn, and the steam generated during the combustion of the materials will enter the exhaust pipe 11 through the gas collecting hopper 26. Then the control valve 12 is opened and enters the condensation system to be collected. The excess residue needs to be discharged after entering the chassis 2. At this time, the dustproof mechanism is opened and the latch 9 is pulled. The latch 9 is compressed and installed in the chassis 2. The spring 8 in the placement groove 21 makes the latch 9 disengage from the latch hole 22 on the chassis 2, at this time the closing plate 6 is pulled, and the connecting block 20 at one end of the connecting rod 7 slides in the second slide groove 19. When the closing plate 6 is fully opened, the latch 9 is released, and the compressed spring 8 pushes the latch 9 into the latch hole 22 of the chassis 2, thereby fixing the closing plate 6, and then connecting the external rod to the connecting bolt 5, and then pushing the connecting bolt 5, the sliding plate 3 slides in the first slide groove 15, and when the slag discharge plate 4 contacts the waste slag in the chassis 2, the slag discharge plate 4 is rotated by the force. When the sliding plate 3 is pulled again, the stop plate 18 on the slag discharge plate 4 contacts and is fixed, and as the sliding plate 3 slides, the waste slag is pulled out of the chassis 2 and discharged at the slag discharge port 16. The waste slag that accidentally falls into the first slide groove 15 will also be pushed into the slag flow port 17 as the sliding plate 3 slides, and then discharged from the chassis 2.

[0036] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded.
