[0027] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0028] like Figure 1 As shown, this utility model provides a multifunctional spray dryer. The dryer 100 includes a body 1, an atomizing mechanism 2, a hot air drying mechanism 3, and a cleaning mechanism 4. The atomizing mechanism 2 is located inside the body 1, the hot air drying mechanism 3 is located outside the body 1, and the cleaning mechanism 4 is located inside the body 1.
[0029] like Figure 3 As shown, the main body 1 is provided with a discharge port 11, an air outlet 12, a feed port 13, and a support foot 14 located below the main body 1.
[0030] In this embodiment, specifically, the air outlet 12 is located next to the feed inlet 13 and is connected to the outside. The atomizing mechanism 2 and the cleaning mechanism 4 are located in the feed inlet 13.
[0031] In this embodiment, specifically, the air outlet 12 is connected to a cyclone separator and a bag filter (not shown) to prevent material from being discharged from the air outlet 12.
[0032] like Figure 1 and Figure 4 As shown, the atomizing mechanism 2 includes a nozzle 21, an atomizing block 22, and an atomizing cover 23. The nozzle 21 is provided with a feed valve 211 at the upper end and a through hole 212 at one end. The atomizing block 22 also includes a bracket 221. The atomizing block 22 is fixed to the lower end of the through hole 212 by the bracket 221. The atomizing cover 23 is sleeved on the lower end of the nozzle 21.
[0033] Liquid material enters the atomizing mechanism 2 through the nozzle 21. The nozzle 21 atomizes the material into tiny droplets. The atomizing baffle 22 and the atomizing cover 23 work together to disperse the droplets evenly.
[0034] like Figure 1-3 As shown, the hot air drying mechanism 3 includes a fan 31, a heating box 32 and an air distribution pipe 33. The fan 31 sends air into the heating box 32, which is equipped with a heating pipe. After the heating box 32 heats the air, the hot air is transported to the main body 1 by the air distribution branch pipe 331.
[0035] In this embodiment, specifically, a filter screen 311 is provided at the connection between the fan 31 and the heating box 32, and the filter screen 311 filters the air entering the heating box 32.
[0036] In this embodiment, specifically, a heating tube 321 is provided inside the heating box 32, and the heating tube 321 heats the air inside the heating box 32.
[0037] In this embodiment, specifically, the air distribution duct 33 is arranged around the bottom of the main body 1, and the air distribution duct 33 is provided with air distribution branch pipes 331, which are connected to the interior of the main body 1.
[0038] The hot air drying unit 3 sends air into the heating chamber 32 via the fan 31 for heating. The hot air is then transported into the main body 1 by the air distribution branch pipe 331. The atomized droplets come into full contact with the hot air, and the moisture evaporates rapidly to form a dry powder.
[0039] like Figure 3 , Figure 4 As shown, the cleaning mechanism 4 includes a cleaning agent inlet pipe 41 and a water distribution pipe 42. The cleaning agent inlet pipe 41 is equipped with a valve 411. The water distribution pipe 42 is sleeved on the outer ring of the atomizing block 22. Water outlet branch pipes 421 are evenly arranged on the water distribution pipe 42. The water outlet of the water outlet branch pipe 421 is vertically aligned with the atomizing block 22.
[0040] In this embodiment, specifically, the water distribution pipe 42 is fixed to the lower end of the atomizing cover 23, and the water distribution pipe 42 is located inside the main body 1.
[0041] In some other embodiments, the outlet of the water branch pipe 421 is tilted upwards and aligned with the atomizing block 22.
[0042] The working process of this multifunctional spray dryer is as follows:
[0043] The cleaning agent enters the water distribution pipe 42 from the cleaning agent inlet pipe 41. The cleaning agent is evenly sprayed onto the surface of the atomizing block 22 through the water outlet branch pipe 421. The sprayed cleaning agent cleans the atomizing block 22 and removes residual materials or other impurities adhering to the surface of the atomizing block 22. The spray direction and uniform distribution of the cleaning agent ensure the comprehensiveness and efficiency of the cleaning.
[0044] The beneficial effects of this multifunctional spray dryer are as follows:
[0045] 1. By adding a cleaning mechanism 4 to the nozzle 21, the accumulation of particulate materials near the nozzle 21 is effectively prevented, the risk of nozzle 21 clogging is reduced, and the stability and reliability of the equipment are improved.
[0046] 2. The cleaning mechanism 4 makes equipment cleaning more convenient and reduces the complexity of manual operation.
