Description

Technical Field

[0001] The utility model relates to the technical field of zinc oxide production, in particular to a heating oxidation device for zinc oxide production. Background Art

[0002] In the production of zinc oxide, a heating furnace is required to heat the material to obtain zinc vapor and blow in oxygen to convert zinc into zinc oxide. Generally speaking, pure oxygen can be directly introduced. Pure oxygen is processed and does not contain impurities, but the production and processing costs are high. Therefore, in some cases, it is chosen to directly introduce air.

[0003] When the air is introduced to produce zinc oxide, if there are too many impurities in the air, it is easy to affect the quality of zinc oxide. Therefore, the air needs to be filtered first, such as adding filter elements, but the filter element will reduce the ventilation efficiency, especially the filter element with a high filtration level, which has a large wind blocking capacity. In order to minimize the impact of the filter element on ventilation, workers will replace the filter element with a low filtration level in time when the air quality is high, but this will cause problems such as increased work intensity and labor costs.

[0004] Therefore, the utility model provides a heating oxidation device for producing zinc oxide. Utility Model Content

[0033] like Figure 1-4 As shown, the utility model provides a heating oxidation device for zinc oxide production, comprising a heating furnace 1 and an air supply port 2 installed on the heating furnace 1 and connected to the interior thereof, wherein the air supply port 2 is used for docking with the single filter element 32 described below.

[0034] In this embodiment, it includes a multi-level filter element assembly 3 with different levels of filtering capabilities, a rotation switching mechanism 4 that drives the filter element mounting plate 31 to rotate to switch different filter elements 32, a dust cover 6 for dust protection of the idle filter element 32, and an installation assembly 5 for installing the dust cover 6 and the rotation switching mechanism 4. Specifically:

[0035] refer to Figure 3 The multi-level filter element assembly 3 includes a pair of filter element mounting plates 31 and four filter elements 32 fixedly mounted between the two filter element mounting plates 31. The four filter elements 32 are distributed in a ring around the central axis of the filter element mounting plates 31. The filter element mounting plates 31 are provided with filter element mounting grooves 311 for the filter element 32 to be inserted and installed, and the two filter element mounting plates 31 are provided with bolt through holes 312 that can be aligned with each other, thereby realizing the disassembly and assembly of the filter element 32 in the filter element mounting plates 31.

[0036] The rotation switching mechanism 4 includes a motor 41, a main shaft 42 coaxially connected to the output shaft of the motor 41, and a main shaft connecting groove 43 coaxially opened on the filter element mounting plate 31. The main shaft 42 is engaged with the main shaft connecting groove 43, and the outer wall of the main shaft 42 is provided with a rectangular key tooth, and the inner wall of the main shaft connecting groove 43 is provided with a rectangular key groove matching the rectangular key tooth. Through the engagement between the two, the multi-level filter element assembly 3 rotates synchronously with the main shaft 42.

[0037] refer to Figure 4 , a pair of dust covers 6 are provided, and the two dust covers 6 are provided with a slot 61 for exposing a single filter element 32 to the outside;

[0038] A pair of dust covers 6 are provided, and bolt connection holes 63 that can be aligned with each other are provided on the opposite surfaces of the two dust covers 6. A rotating cavity 62 is provided on the opposite surfaces of the two dust covers 6 for the multi-level filter element assembly 3 to rotate therein, and a main shaft rotating hole 64 is provided concentrically on the two dust covers 6 for the main shaft 42 to move through. Thus, the multi-level filter element assembly 3 can be rotated in the dust cover 6, so that a single filter element 32 can be exposed to the outside to filter the ventilation of the air supply port 2, and the remaining filter elements 32 are located in the dust cover 6 for dust protection.

[0039] refer to Figure 2 The mounting assembly 5 includes a connecting strip 51 fixedly connected to the air outlet 2 at one end by bolts and a motor mounting box 52 fixedly connected to the other end of the connecting strip 51. The motor 41 is fixedly sleeved inside the motor mounting box 52, and one of the dust covers 6 is provided with a threaded hole 65 fixedly connected to the end of the motor mounting box 52 by bolts. The connecting strip 51 is provided with a bolt hole 511 fixedly connected to the outer shell of the motor mounting box 52 and the outer wall of the air outlet 2 by bolts. In this way, the dust cover 6 and the rotary switching mechanism 4 can be disassembled and installed on the air outlet 2.

[0040] The working principle of this embodiment is as follows: through the design of a multi-level filter element assembly 3 and a rotating switching mechanism 4 that can drive the multi-level filter element assembly 3 to rotate, the filter elements 32 of different filtration levels can be quickly aligned with the air outlet 2 without manual replacement; through the design of a dust cover 6 with a slot 61, not only can the filter element 32 in use be detached from the outside, but the filter element 32 in an idle state can also be protected from dust; through the detachable design of the structures of the multi-level filter element assembly 3, the dust cover 6, and the mounting assembly 5, the filter element 32 can be quickly cleaned and replaced.

[0041] Specifically, when the air quality in the production environment changes, the filter element 32 can be switched by starting the motor 41. The motor 41 can be started using an existing remote control mode combined with wireless transmission technology. The specific start-up mode can be selected according to actual production needs. After the motor 41 is started, its output shaft drives the main shaft 42 to rotate, and the main shaft 42 drives the filter element mounting plate 31 to rotate, so that the filter element 32 with different filtering capabilities is rotated to the slot 61 and docked with the port of the air outlet 2 to achieve different degrees of filtering. The lower the filtering degree, the stronger the ventilation capacity, which is adapted to the corresponding air quality.

[0042] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
