A heat exchange box 6 is installed at the end of the hot air pipe 4 near the sprayer 2. An air inlet pipe 11 is inserted through the outer wall of the tower body 1, and a blower 12 is installed on the surface of the air inlet pipe 11. An air filter box 13 is connected to the bottom of the air inlet pipe 11. A serpentine section 18 is provided on the surface of the air inlet pipe 11, and the serpentine section 18 extends to the inside of the heat exchange box 6. An air inlet 23 is opened on the surface of the air filter box 13, and an activated carbon filter 22 and a photocatalytic filter 21 are installed sequentially from top to bottom inside the air filter box 13. A discharge pipe 7 is connected to the bottom of the tower body 1. A primary discharge nozzle 8 is provided at the bottom of the discharge pipe 7. A cyclone separator 9 is installed on the right side of the tower body 1, and the feed end of the cyclone separator 9 is connected to the discharge pipe 7 through a pipe. A secondary discharge nozzle 10 is provided at the bottom of the cyclone separator 9. A particle concentration sensor 20, a pressure relief valve 14, and a temperature sensor 19 are installed sequentially on the right side of the top surface of the tower body 1. The control method of this utility model is controlled by manually starting and stopping the switch. The wiring diagram of the power components and the power supply are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail. The setting of the pressure relief valve 14 facilitates the pressure relief of the tower body 1 and prevents a series of safety hazards caused by excessive pressure in the tower body 1. The principle of the heater 5 and the cyclone separator 9 is existing known technology and there are mature products. Therefore, their principle will not be explained further.

[0024] In one embodiment, the lower part of the tower body 1 is provided with a conical section, and the inner side of the conical section is provided with a horn shell 15. The upper surface of the horn shell 15 is provided with a plurality of springs 17 connected to the inner wall of the tower body 1. Two steel bars 16 are welded to the inner wall of the conical section of the tower body 1, and both steel bars 16 extend to the inner side of the bottom opening of the horn shell 15.

[0025] In one embodiment, the air inlet pipe 11 extends to the inside of the tower body 1, and one end of the air inlet pipe 11 is provided with a bent nozzle, and the bent nozzle is arranged towards the nozzle of the sprayer 2. Through the bent nozzle of the air inlet pipe 11, the temperature of the liquid sprayed by the nozzle of the sprayer 2 is easily reduced.

[0026] In one embodiment, the inner wall of the air filter box 13 is provided with an ultraviolet lamp, and the ultraviolet lamp is arranged towards the photocatalyst filter screen 21. Through the arrangement of the ultraviolet lamp, the long-acting sterilization and air filtration of the photocatalyst filter screen 21 are facilitated (which is a known prior art and will not be described in detail).

[0027] In one embodiment, the top of the cyclone separator 9 is provided with an air outlet pipe, and the secondary discharge nozzle 10 of the cyclone separator 9 is at the same height as the primary discharge nozzle 8. Through the arrangement of the cyclone separator 9, the gas-solid separation of the gas containing the composite probiotics is facilitated.

Through the display panel, the detection data of the particle concentration sensor 20 and the temperature sensor 19 can be displayed in time, so as to avoid the occurrence of dust explosion.

[0029] Working principle:

[0030] In use, under the action of the external pump body, the composite probiotic liquid is extracted and injected into the sprayer 2 through the liquid pipe 3. The heater 5 and the fan matched with the heater 5 are started, so that hot air is filled into the sprayer 2 through the hot air pipe 4, until the atomized composite probiotic liquid is mixed with the hot air and sprayed into the tower body 1. When the temperature data detected by the temperature sensor 19 is greater than the survival temperature range of the composite probiotics or the particle concentration sensor 20 detects that the particle concentration of the tower body 1 exceeds the static explosion limit value, the air blower 12 is started to work, so that the air inlet end of the air blower 12 extracts the air of the air filter box 13, so that the air inlet 23 of the air filter box 13 sucks the external cold air, and the activated carbon filter screen 22 and the photocatalyst filter screen 21 built-in installed in the air filter box 13 perform air dust filtering and sterilization, so that the clean gas blows to the spraying end of the sprayer 2 through the serpentine part of the air inlet pipe 11. Since the serpentine part 18 of the air inlet pipe 11 is inside the heat exchange box 6, the hot air passing through the heat exchange box 6 exchanges heat with the cold air of the serpentine part 18, on the one hand, the temperature of the tower body 1 in the "high temperature" state is reduced, on the other hand, the newly incoming air can dilute the particle concentration in the tower body 1. The composite probiotic powder falling to the discharge pipe 7 is discharged through the primary discharge nozzle 8, and then the particle gas in the discharge pipe 7 is sucked by the cyclone separator 9, and then gas-solid separation is performed, so that a small part of the composite probiotic powder is discharged from the secondary discharge nozzle 10 at the bottom of the cyclone separator 9.

[0031] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
