Technical Field

[0001] The utility model relates to the technical field of baking, in particular to a device for automatically adding cleaning liquid to a hot air furnace. Background Art

[0002] When the oven is in use, the oil deposited on the bread will carbonize into black dirt when encountering high temperature. The dirt will stick to the oven and is difficult to clean, which can easily breed bacteria. Therefore, the cleaning problem of the oven has attracted more and more attention. Although some oven manufacturers have installed a cleaning system on the top of the oven, the cleaning effect is not ideal, and manual secondary cleaning is often required, which not only consumes a lot of manpower and time costs, but also wastes water resources.

However, the cleaning liquid needs to be manually added into the oven cavity, and then the cleaning system is started to clean the oven cavity. Manual addition of cleaning liquid results in cumbersome cleaning work and inaccurate dosage of cleaning agent. Utility Model Content

[0026] Embodiment 1

[0027] See also Figure 1 , Figure 1 This is a structural schematic diagram of an automatic cleaning liquid adding device for a hot blast furnace. The automatic cleaning liquid adding device for a hot blast furnace in this example includes a furnace 1, a water supply structure 2, a liquid injection structure 3 and a control system. The furnace 1 is used as a hot blast furnace container for accommodating items to be baked, and for carrying the water supply structure 2, the liquid injection structure 3 and the control system. The water supply structure 2 is used to supply water to the cleaning device of the hot blast furnace, the liquid injection structure 3 is used to inject cleaning liquid into the cleaning device, and the control system is used to control the water supply structure 2 and the liquid injection structure 3.

[0028] See also Figure 2 and Figure 3 And review Figure 1 , Figure 2 It is a schematic diagram of the water supply structure and the liquid injection structure. Figure 3It is a schematic diagram of the coordination relationship between the cleaning liquid tank and the sensing element, wherein the water supply structure 2 includes a water tank 21, a first water injection pipe 22 and a circulating pump 23. The water tank 21 is arranged on the outer wall of the furnace 1, and the circulating pump 23 is connected to the water tank 21. One end of the first water injection pipe 22 is connected to the circulating pump 23, and the other end extends into the furnace 1 and is connected to the cleaning device. The liquid injection structure 3 includes a cleaning liquid tank 31 and a peristaltic pump 32. The cleaning liquid tank 31 is arranged on the outer wall of the furnace 1, and the cleaning liquid tank 31 is detachably connected to the furnace 1. The peristaltic pump 32 is respectively connected to the cleaning liquid tank 31 and the water tank 21, and the circulating pump 23 and the peristaltic pump 32 are respectively electrically connected to the control system; the cleaning device can be a water-throwing device that can be realized by those skilled in the art including a rotating spray head, a high-pressure spray head, etc.

[0029] In specific applications, the staff can set the working time of the peristaltic pump 32 through the control system, so as to control the amount of cleaning liquid injected into the water tank 21. The peristaltic pump 32 injects the cleaning liquid in the cleaning liquid tank 31 into the water tank 21. The water tank 21 is connected to an external water source through a pipeline. The circulating pump 23 injects the water in the water tank 21 into the cleaning device. The cleaning inside the hot air furnace can be achieved by controlling the cleaning device in the furnace 1 by the control system.

[0030] In this way, by setting up the cleaning liquid tank 31 and the peristaltic pump 32, the cleaning liquid can be automatically injected into the cleaning device in the hot air furnace without the need for manual injection by the staff, thereby reducing the labor intensity of the staff. By adjusting the working time of the peristaltic pump 32 through the control system, the amount of cleaning liquid can be controlled, thereby achieving precise control of the amount of cleaning liquid.

[0031] Furthermore, the liquid injection structure 3 also includes a sensor 33 , which is disposed in the cleaning liquid tank 31 and is electrically connected to the control system.

[0032] Specifically, the liquid injection structure 3 includes three sensing components 33, which are used to measure the lowest liquid level, the highest liquid level and the common end liquid level of the cleaning liquid tank 31 in turn. The sensing components 33 can be contactless liquid level sensors or corrosion-resistant probes, which are installed in the cleaning liquid tank 31.

[0033] In this way, the remaining amount of cleaning liquid in the cleaning liquid tank 31 can be detected. When the remaining amount of cleaning liquid in the cleaning liquid tank 31 is lower than a preset value, the control system can issue a prompt to facilitate the staff to replace the cleaning liquid in the cleaning liquid tank 31 to avoid the lack of cleaning liquid affecting the cleaning effect.

[0034] Furthermore, the liquid injection structure 3 includes a plurality of peristaltic pumps 32 , each of which is connected to the water tank 21 , and each of which is electrically connected to the control system.

[0035] In this example, the automatic cleaning liquid adding device of the hot blast furnace includes two liquid injection structures 3, and the two cleaning liquid tanks 31 are both arranged outside the furnace 1. The peristaltic pump 32 of each liquid injection structure 3 is connected to the water tank 21, and the two peristaltic pumps 32 are electrically connected to the control system respectively.

[0036] In this way, cleaning liquids with different effects can be injected at the same time, such as removing odor, dirt, and oil stains, thereby improving the cleaning effect of the hot air furnace.

[0037] Furthermore, the water supply structure 2 also includes a second water injection pipe 24 , one end of which is connected to the water tank 21 , and the other end of which extends into the furnace 1 .

[0038] Specifically, the first water injection pipe 22 extends into the furnace 1 above the furnace 1 , and the second water injection pipe 24 extends into the furnace 1 below the furnace 1 . Both the first water injection pipe 22 and the second water injection pipe 24 are connected to the cleaning device in the furnace 1 .

[0039] In this way, the water injection efficiency of the automatic cleaning liquid adding device of the hot blast stove is improved.

[0040] Furthermore, the furnace 1 is a double-layer hollow structure.

[0041] In this way, when the automatic cleaning liquid adding device for the hot blast stove is applied to the hot blast stove, the baking quality of the hot blast stove can be improved, and at the same time, the heat preservation effect can be played, which is convenient for energy saving.

[0042] Furthermore, the furnace 1 is made of 304 stainless steel or 306 stainless steel.

[0043] Thus, 304 stainless steel or 306 stainless steel can ensure that the furnace 1 is safe, non-toxic, corrosion-resistant, high-temperature-resistant and wear-resistant.

By adjusting the working time of the peristaltic pump through the control system, the amount of cleaning liquid can be controlled, thereby achieving precise control of the amount of cleaning liquid.
