An odor removal device for a food deodorizer

Abstract

The present invention discloses an odor removal device for a food deodorizer, which relates to the technical field of food deodorizers. The present invention has novel design and ingenious structure. By arranging a heating chamber in the middle of the reaction chamber and fixedly arranging a flow guide plate between the heating chamber and the ultraviolet chamber, external air enters the heating chamber from the air inlet, and at the same time, the hot air in the heating chamber flows out from the air outlet. Under the guiding action of the flow guide plate, it enters the second catalytic chamber and finally enters the exhaust chamber to be discharged. During the process of the hot air flowing through the second catalytic chamber, sufficient and effective heating of the catalyst that needs to be heated is achieved. On the other hand, during the exhaust process of the exhaust chamber, continuous negative pressure is generated inside the reaction chamber, so that the air to be deodorized is sucked into the ultraviolet chamber, and then successively flows through the first catalytic chamber, the second catalytic chamber and the exhaust chamber, so that the air to be deodorized is in full contact with the catalysts in the first catalytic chamber and the second catalytic chamber and reacts fully, thereby greatly improving the deodorization effect.

Description

Technical Field

[0001] The present invention relates to the technical field of food deodorizing machines, and particularly to an odor removing device for a food deodorizing machine. Background Art

[0002] In existing food deodorizing machines, generally, microorganisms ferment and decompose food waste, and then ultraviolet lamps in the odor removing device synthesize ozone from oxygen in the air for sterilization and disinfection to remove odor components in the air. Then, a catalyst is used to promote the decomposition of ozone to remove the generated odor in the air; when some catalysts are in use, they need to be heated to improve the reaction efficiency. However, in traditional odor removing devices, the heating equipment is directly horizontally arranged in the middle of the catalyst, so that the catalyst that needs to be heated cannot be fully heated. On the other hand, the air that needs to be deodorized is difficult to come into full contact with the catalyst, affecting the deodorizing effect. Summary of the Invention

[0003] The purpose of the present invention is to achieve sufficient and effective heating of the catalyst that needs to be heated, and at the same time enable the air that needs to be deodorized to come into full contact with the catalyst, greatly improving the deodorizing effect.

[0004] In order to achieve the above purpose, the technical solutions adopted by the present invention are as follows:

[0005] An odor removing device for a food deodorizing machine includes a housing and an outer cover. The outer cover covers the housing. An ultraviolet chamber, a reaction chamber, and an exhaust chamber that are sequentially connected are provided inside the housing. A heating chamber is arranged in the middle of the reaction chamber. An air inlet is provided on the inner wall of the heating chamber, and an air outlet is provided at one end of the heating chamber close to the ultraviolet chamber. A flow guiding plate is fixedly arranged between the heating chamber and the ultraviolet chamber, and the flow guiding plate divides the reaction chamber into a first catalytic chamber and a second catalytic chamber that are interconnected.

[0006] Further, an air inlet is provided on the side wall of the ultraviolet chamber.

[0007] Further, an auxiliary air inlet is also provided on the side wall of the ultraviolet chamber.

[0008] Further, an exhaust port is provided on the side wall of the exhaust chamber.

[0009] Further, columns are fixedly arranged inside both the first catalytic chamber and the second catalytic chamber.

[0010] Further, a buffer chamber is also provided between the reaction chamber and the exhaust chamber, and the reaction chamber, the buffer chamber, and the exhaust chamber are sequentially connected.

[0011] Further, a support plate is fixedly arranged inside the heating chamber.

[0012] Further, a partition is fixedly arranged inside the second catalytic chamber.

[0013] Further, filter plates are arranged between the ultraviolet chamber and the reaction chamber, between the first catalytic chamber and the second catalytic chamber, and between the reaction chamber and the exhaust chamber.

[0014] Further, the outer cover includes an ultraviolet chamber cover, a reaction chamber cover, and a heating chamber cover. The ultraviolet chamber cover is arranged on the ultraviolet chamber, the reaction chamber cover is arranged on the reaction chamber, and the heating chamber cover is arranged on the heating chamber.

[0015] The beneficial effects of the present invention are as follows: By arranging a heating chamber in the middle of the reaction chamber and fixedly arranging a diversion plate between the heating chamber and the ultraviolet chamber, outside air enters the heating chamber from the air inlet, and at the same time, the hot air in the heating chamber flows out from the air outlet and enters the second catalytic chamber under the diversion of the diversion plate. After the hot air flows through the second catalytic chamber, it enters the exhaust chamber and is discharged. During the process of the hot air flowing through the second catalytic chamber, the catalyst that needs to be heated is heated sufficiently and effectively. On the other hand, during the exhaust process of the exhaust chamber, a continuous negative pressure is generated inside the reaction chamber, so that the air that needs to be deodorized is sucked into the ultraviolet chamber, and then flows through the first catalytic chamber, the second catalytic chamber, and the exhaust chamber in sequence, so that the air that needs to be deodorized comes into full contact with the catalysts in the first catalytic chamber and the second catalytic chamber and reacts fully, thereby greatly improving the deodorization effect.

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] As Figures 1 to 5 shown, an odor removal device of a food deodorizer includes a housing 1 and an outer cover 2. The outer cover 2 covers the housing 1. Inside the housing 1, there are sequentially connected an ultraviolet chamber 3, a reaction chamber 4, a buffer chamber 5 and an exhaust chamber 6. The outer cover 2 includes an ultraviolet chamber cover 21, a reaction chamber cover 22 and a heating chamber cover 23. The ultraviolet chamber cover 21 covers the ultraviolet chamber 3, the reaction chamber cover 22 covers the reaction chamber 4, and the heating chamber cover 23 covers the heating chamber 7.

[0032] Please refer to Figure 3 again. An air inlet 31 is provided on the side wall of the ultraviolet chamber 3. The air inlet 31 is used to directly introduce the air to be deodorized into the ultraviolet chamber 3. An auxiliary air inlet 32 is also provided on the side wall of the ultraviolet chamber 3. The auxiliary air inlet 32 is used to suck a small amount of overflowing odor into the ultraviolet chamber 3.

[0033] An exhaust port 61 is provided on the side wall of the exhaust chamber 6. A exhaust fan is provided at the exhaust port 61, which is used to extract the air inside the exhaust chamber 6 to the outside, so as to continuously generate negative pressure inside the buffer chamber 5, the reaction chamber 4 and the ultraviolet chamber 3, which is beneficial for the air to be deodorized to enter the ultraviolet chamber 3 from the air inlet 31 and the auxiliary air inlet 32, and flow through the reaction chamber 4, the buffer chamber 5 and the exhaust chamber 6 in sequence, and finally be discharged through the exhaust port 61.

[0034] A UV lamp is fixedly arranged in the ultraviolet chamber 3. When the UV lamp works, it emits ultraviolet light to disinfect and sterilize the air to be deodorized, and synthesizes ozone from the oxygen in the air to perform preliminary treatment on the air to be deodorized.

[0035] A heating chamber 7 is provided in the middle of the reaction chamber 4. An air inlet 71 is provided on the inner wall of the heating chamber 7. The air inlet 71 is communicated with the outside air. An air outlet 72 is provided at one end of the heating chamber 7 close to the ultraviolet chamber 3. A flow guide plate 8 is fixedly arranged between the heating chamber 7 and the ultraviolet chamber 3. The flow guide plate 8 divides the reaction chamber 4 into a first catalytic chamber 41 and a second catalytic chamber 42 which are communicated with each other. The air outlet 72 is communicated with the second catalytic chamber 42.

[0036] When the exhaust fan extracts the air inside the exhaust chamber 6 outwards, it creates a continuous negative pressure inside the buffer chamber 5, reaction chamber 4, and heating chamber 7, so that the outside air is inhaled into the heating chamber 7 from the air inlet 71. The hot air in the heating chamber 7 flows out from the air outlet 72, and under the guiding action of the guiding plate 8, it enters the second catalytic chamber 42. After the hot air flows through the second catalytic chamber 42, it successively enters the buffer chamber 5 and the exhaust chamber 6, and finally is discharged through the exhaust port 61.

[0037] A support plate 73 is fixedly arranged inside the heating chamber 7. At the same time, heating rods are also arranged inside the heating chamber 7. The heating rods are mounted on the support plate 73 to prevent the heating rods from directly contacting the housing 1, resulting in excessive local temperature.

[0038] Aluminum oxide catalyst is arranged in the first catalytic chamber 41. The air to be deodorized enters the first catalytic chamber 41 from the ultraviolet chamber 3, and then is dehumidified and deodorized by the aluminum oxide catalyst. Manganese copper catalyst is arranged in the second catalytic chamber 42. After the hot air enters the second catalytic chamber 42 from the heating chamber 7, the manganese copper catalyst is heated. After the air to be deodorized enters the second catalytic chamber 42 from the first catalytic chamber 41, the ozone in it is catalytically decomposed by the manganese copper catalyst to achieve the purpose of deodorization.

[0039] Columns 9 are fixedly arranged inside both the first catalytic chamber 41 and the second catalytic chamber 42. The columns 9 have two functions. One is to facilitate separating the overly stacked catalysts to make the air circulation smoother; the other is to facilitate heat conduction to make the heat distribution uniform.

[0040] A partition plate 421 is fixedly arranged inside the second catalytic chamber 42. The partition plate 421 divides the second catalytic chamber 42 into multiple small compartments, and the multiple small compartments are connected end to end, so as to facilitate the air to fully contact the manganese copper catalyst in the second catalytic chamber 42, extend the reaction time, and further improve the deodorization effect.

[0041] Filter plates are arranged between the ultraviolet chamber 3 and the reaction chamber 4, between the first catalytic chamber 41 and the second catalytic chamber 42, and between the reaction chamber 4 and the exhaust chamber 6. The function of the filter is to ensure the free flow of air between the ultraviolet chamber 3, the first catalytic chamber 41, the second catalytic chamber 42, and the exhaust chamber 6, while preventing the aluminum oxide catalyst in the first catalytic chamber 41 and the manganese copper catalyst in the second catalytic chamber 42 from leaking out.

[0042] The working principle of the present invention is as follows: 1. When the exhaust fan is turned on, the air inside the exhaust chamber 6 is extracted outwards, creating a continuous negative pressure inside the buffer chamber 5, reaction chamber 4, heating chamber 7, and ultraviolet chamber 3;

[0043] 2. The outside air is inhaled from the air inlet 71 into the heating chamber 7, and the hot air in the heating chamber 7 flows out from the air outlet 72. Under the guiding action of the guiding plate 8, it enters the second catalytic chamber 42. After the hot air flows through the second catalytic chamber 42, it enters the buffer chamber 5 and the exhaust chamber 6 in sequence, and finally is discharged through the exhaust port 61. While the hot air flows through the second catalytic chamber 42, it heats the manganese-copper catalyst.

[0044] 3. The air to be deodorized enters the ultraviolet chamber 3 from the air inlet 31. The ultraviolet light emitted by the UV lamp disinfects and sterilizes the air to be deodorized, and synthesizes ozone from the oxygen in the air to preliminarily treat the air to be deodorized.

[0045] 4. The air to be deodorized enters the first catalytic chamber 41 from the ultraviolet chamber 3, and is dehumidified and deodorized by the alumina catalyst.

[0046] 5. The air to be deodorized enters the second catalytic chamber 42 from the first catalytic chamber 41, and the ozone in it is catalytically decomposed by the manganese-copper catalyst to achieve deodorization. The deodorized air flows through the buffer chamber 5 and the exhaust chamber 6 in sequence, and finally is discharged through the exhaust port 61.

[0047] The above embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary engineering and technical personnel in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
