Detailed Embodiments

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] The following will describe the embodiments of the present utility model in conjunction with Figures 1 to 6 , to describe the embodiments of the present utility model.

[0031] According to an embodiment of the present utility model, in a first aspect, a spraying device is provided, which includes a water supply pipeline 10, an atomization assembly 20, a control assembly 30, and a dust monitor 40. The atomization assembly 20 is communicated with the water supply pipeline 10, and the nozzle of the atomization assembly 20 is adapted to be arranged facing the part to be wetted 80; the control assembly 30 includes a control valve 31, and the control valve 31 is communicated between the atomization assembly 20 and the water supply pipeline 10; the dust monitor 40 is electrically connected to the control valve 31, and the dust monitor 40 is adapted to detect the dust content in the protective cover of the dry granulator.

[0032] When applying the spraying device of this embodiment, by setting the dust monitor 40, in the no-load running state after the granulation operation is completed, first, the dust content of the part to be wetted 80 in the protective cover of the dry granulator is monitored and predicted. When the dust content of any part to be wetted 80 exceeds the defined requirements, the dust monitor 40 transmits an electrical signal to the control valve 31, and then the control valve 31 immediately opens to supply water, and the part to be wetted 80 is wetted through the atomization assembly 20, preventing the internal dust from diffusing outward when the protective cover is opened, thereby ensuring the health and safety of the operator and the cleanliness of the production environment.

[0033] It should be noted that the dust monitor 40 starts to work in the no-load running state after the granulation operation of the dry granulator is completed, so as to prevent the spraying device from being started by a misinstruction during the granulation process of the dry granulator.

[0034] Furthermore, the control assembly 30 further includes a control host, and the control host is electrically connected to the dust monitor 40 to control the start of the dust monitor 40, receive the electrical signal of the dust monitor 40 and transmit it to the control valve 31.

[0035] It should be noted that when changing batches in the production of the dry granulator, the inside of the dry granulator needs to be cleaned to avoid powder mixing. In the related art, the operator needs to open the protective cover of the dry granulator to clean the inside of the dry granulator. However, after the material preparation is completed, fine dust will float inside the dry granulator, and excessive fine dust is easily inhaled by the operator, affecting health.

[0036] It can be understood that for the spraying device of this embodiment, after granulation is completed, the dust monitor 40 detects the internal dust content of the protective cover. If the dust monitor 40 detects that the internal dust content of the protective cover has exceeded the specified requirements, the dust monitor 40 transmits the information to the control valve 31 through an electrical signal to connect the water supply pipeline 10 with the atomization assembly 20. The atomization assembly 20 starts to spray atomized water, and the dust inside the protective cover adheres to the water droplets, finally achieving the effect of a dust-free interior of the protective cover.

[0037] Specifically, the dust monitor 40 further includes an indicator light, which displays different colors according to the detected different dust contents for the operator to judge the situation inside the protective cover.

[0038] Furthermore, the dust monitor 40 further includes a temperature detection unit to detect the temperature inside the protective cover.

[0039] In one embodiment, as Figure 1 and Figure 2 shown, the control assembly 30 further includes a water distributor 32. The water distributor 32 is connected to the control valve 31. There are several atomization assemblies 20. The water distributor 32 includes water outlets, and there are several water outlets. The atomization assembly 20 includes water inlets, and the water inlets of several atomization assemblies 20 are in one-to-one correspondence and connected to the several water outlets. By using the water distributor 32, it can ensure the stable water outlet flow of each water pipeline and avoid inconsistent effects of individual atomization assemblies 20; by setting several atomization assemblies 20, multiple parts of the dry granulator can be comprehensively wetted, improving the wetting ability of the spraying device.

[0040] Specifically, as Figure 1 shown, there are three water distributors 32, and each water distributor 32 is provided with two water outlets, and each drain port is connected to an atomization assembly 20.

[0041] Specifically, please refer to Figure 1 , the parts to be wetted 80 include a feeding area 81, a fine powder collection area 82, a roller area 83, a first granulation area 84, a second granulation area 85, and a third granulation area 86.

[0042] It should be noted that multiple atomization assemblies 20 can be arranged in one-to-one correspondence with multiple parts to be wetted 80; multiple atomization assemblies 20 can also wet one part to be wetted 80 simultaneously to enhance the wetting effect.

[0043] In yet another embodiment, as Figure 3 shown, there is only one water distributor 32, and each water distributor 32 is provided with multiple water outlets.

[0044] In yet another embodiment, as Figure 6As shown, a plurality of control valves 31 are provided, and a plurality of atomizing assemblies 20 are provided. The atomizing assembly 20 includes a water inlet, and the plurality of control valves 31 are in one-to-one correspondence and communication with the water inlets of the plurality of atomizing assemblies 20. By setting the control valves 31 and the atomizing assemblies 20 in one-to-one correspondence, the on-off control of each atomizing assembly 20 can be respectively performed to meet different requirements and improve the atomizing effect of the spraying device.

[0045] In one embodiment, as Figure 1 and Figure 4 shown, the atomizing assembly 20 includes an adjusting member 21 and a spraying member 22. The adjusting member 21 is in communication with the spraying member 22, the adjusting member 21 is in communication with the control valve 31, and the nozzle of the spraying member 22 is adapted to be arranged facing the part 80 to be wetted. By providing the adjusting member 21, the spraying flow rate of the spraying member 22 is adjusted to improve the atomizing effect of the spraying device.

[0046] It should be noted that in other alternative embodiments, the atomizing assembly 20 can also use an adjustable nozzle that simultaneously has the functions of adjustment and spraying, which can also ensure the effect of reducing the internal dust content of the protective cover.

[0047] In one embodiment, the control valve 31 is an electromagnetic reversing valve.

[0048] It should be noted that after receiving the signal from the dust monitor 40, the electromagnetic reversing valve is electromagnetically commutated to connect the water supply pipeline 10 and the atomizing assembly 20.

[0049] It is worth noting that the automatic connection of the water supply pipeline 10 and the atomizing assembly 20 is realized through the electromagnetic reversing valve, saving labor.

[0053] Specifically, the drainage port is opened below the protective cover so that the waste water can be discharged by gravity from below.

[0056] Specifically, in this embodiment, a total of four dry granulators are provided. The water supply pipelines 10 of the four dry granulators are respectively communicated with the water source 50 to ensure that the water source 50 supplies water to the dry granulators simultaneously; the drainage pipelines 70 of the four dry granulators are respectively communicated with the collection tank 60 to ensure the collection of the wetted wastewater.

[0057] Of course, in other alternative embodiments, the number of dry granulators in the spraying system can also be adjusted according to actual needs.
