Description

Technical Field

[0001] This utility model relates to the field of deodorizing fan technology, and in particular to a deodorizing fan for a fecal drying machine. Background Technology

[0002] The existing patent publication number (CN214596613U8) discloses a counter-current deodorizing fan, including: a support base, a water spray assembly, a filter assembly, and a fan assembly. The fan assembly is disposed above the support base, the water spray assembly is disposed inside the support base, and the filter assembly is disposed inside the support base. The filter assembly includes: a packing support, a packing block, and a water baffle plate. The packing support is disposed inside the support frame, the packing block is disposed above the packing support, and the water baffle plate is disposed below the support frame. There is a distance H between the upper surface of the packing block and the lower surface of the water baffle plate. A chemical mixer is provided below the support base. During the upward movement of the air, it comes into contact with the filter component soaked in the deodorizing solution, and thus interacts with the deodorizing solution. However, the further away the filter component is from the deodorizing solution, the less effective the interaction between the air and the deodorizing solution becomes, resulting in poor mixing of the deodorizing solution with the air. Furthermore, the patent creates a vertically upward airflow, which further reduces the mixing effect when the air comes into contact with the filter component soaked in the deodorizing solution during airflow.

[0003] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content

[0004] This utility model provides a deodorizing fan for a fecal drying machine to solve the technical problems mentioned in the background art, which are that the further away the filter component is from the deodorizing liquid, the lower the degree of interaction between it and the deodorizing liquid, resulting in poor mixing of the deodorizing liquid with the air. Furthermore, the aforementioned patent forms a vertically upward airflow, which results in poor mixing effect when the air comes into contact with the filter component wetted by the deodorizing liquid during the airflow process.

[0005] The present invention adopts the following technical solution to solve the above-mentioned technical problems: A deodorizing fan for a fecal drying machine includes a fan body shell and a fan duct fixed on the fan body shell. The fan body shell and the fan duct are connected and a through air inlet is provided on the four sides of the lower end of the fan body shell. An axial flow fan is bolted into the fan casing. When the axial flow fan is powered on, it generates an upward airflow, which creates a negative pressure inside the fan body casing. This negative pressure then draws in ambient air through the air inlet to form a flowing airflow. The deodorizing atomizing device includes a deodorizing liquid tank, a pump, an electrical control box, a circulating pipe, and atomizing nozzles. The circulating pipe is welded and fixed inside the main casing of the fan body via a fixing bracket. The atomizing nozzles are fixed in a ring array inside the circulating pipe with the spray nozzles pointing towards the axis of the circulating pipe. The circulating pipe is connected to the pump, and the pump is connected to the deodorizing liquid tank. After the electrical control box controls the pump to start, it draws out the deodorizing liquid from the deodorizing liquid tank and sprays it out in a water mist form through the atomizing nozzles. After the deodorizing liquid is sprayed out in a water mist form, it mixes with the flowing airflow.

[0006] Preferably, a conical air guide shroud is also fixed inside the main body shell of the fan. The inner wall of the conical air guide shroud is inclined. The area of ​​the upper port of the conical air guide shroud is smaller than the area of ​​the lower port of the conical air guide shroud. The upper port of the conical air guide shroud forms a constriction in the airflow path of the main body shell of the fan. When the axial flow fan blows air upward, the external air enters the main body shell of the fan through the air inlet under negative pressure. After entering the main body shell of the fan, the external air quickly mixes with the water mist deodorizing liquid, and the air pressure is increased by passing through the constriction formed by the conical air guide shroud during the upward process.

[0007] Preferably, it further includes a mixer, which is disposed inside the main housing of the fan body and located between the conical guide shroud and the axial flow fan. The mixer includes an arc-shaped guide wall with a diameter greater than the side length of the upper port of the conical guide shroud.

[0008] Preferably, the mixer includes an auxiliary fixing frame, a rotating shaft, a flow guide shroud, and flow guide vanes. The auxiliary fixing frame is fixed at the top circular hole of the fan body shell to fix the rotating shaft. The lower end of the rotating shaft is provided with a bearing. The flow guide shroud is rotatably mounted on the lower end of the rotating shaft through the bearing. The rotating shaft, flow guide vanes, and circulation pipe are coaxially arranged.

[0009] Preferably, the air guide is a hollow hemispherical structure. When the air carrying the deodorizing liquid water mist rises and contacts the air guide, it forms a descending airflow under the comprehensive airflow guidance of the top wall plane of the fan body shell, and forms a vortex swirling along the inner circular wall surface of the air guide.

[0010] Preferably, guide vanes are fixedly provided at annular intervals on the outer circular wall surface of the guide shroud, so that when the airflow rises and acts on the guide vanes, the rising airflow drives the guide shroud to rotate.

[0011] The advantages and positive effects of this utility model are: After the deodorizing liquid is sprayed out in the form of water mist, it quickly mixes with the air entering the main casing of the fan. Under the narrowing effect of the conical guide shroud, it is compressed, reducing the gap between the deodorizing liquid water mist particles, thereby increasing the degree of mixing with the air. As the air and deodorizing liquid water mist continue to rise, they are guided into the interior of the guide shroud by the rotating guide shroud and guide vanes, forming a vortex cyclone of backflow. This increases the mixing and contact time between the deodorizing liquid water mist and the air inside the main casing of the fan, improving the degree of mixing and contact between the air and the deodorizing liquid water mist in the dynamic process.

Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0016] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance. The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings: like Figure 1-6 As shown, the deodorizing fan for a fecal drying machine of the present invention includes a fan body shell 11 and a fan duct 10 fixed on the fan body shell 11. The fan body shell 11 and the fan duct 10 are connected and a through air inlet 16 is provided on the four sides of the lower end of the fan body shell 11. An axial flow fan 12 is bolted inside the fan casing 10. When the axial flow fan 12 is powered on, it generates an upward airflow, which creates a negative pressure inside the fan body shell 11. This negative pressure then draws in external ambient air through the air inlet 16 to form a flowing airflow. The deodorizing atomizing device includes a deodorizing liquid tank 14, a pump 15, an electrical control box 13, a circulation pipe 24, and atomizing nozzles 25. The circulation pipe 24 is welded and fixed inside the main casing 11 of the fan body by a fixing bracket 23. The atomizing nozzles 25 are fixed in a ring array inside the circulation pipe 24 with the spray nozzles pointing towards the axis of the circulation pipe 24. The circulation pipe 24 is connected to the pump 15, and the pump 15 is connected to the deodorizing liquid tank 14. After the electrical control box 13 controls the pump 15 to start, it draws out the deodorizing liquid from the deodorizing liquid tank 14 and sprays it out in a water mist form through the atomizing nozzles 25. After the deodorizing liquid is sprayed out in a water mist form, it mixes with the flowing air. Compared with the prior art, which passes odorous air through a filter assembly containing deodorizing liquid, this application effectively improves the mixing degree of air and deodorizing liquid.

[0017] Preferably, a conical guide shroud 22 is also fixedly installed inside the main casing 11 of the fan. The inner wall of the conical guide shroud 22 is inclined, and the area of ​​the upper port of the conical guide shroud 22 is smaller than the area of ​​the lower port of the conical guide shroud 22 (e.g., ...). Figure 1 , 4The upper port of the conical guide shroud 22 forms a constriction in the airflow path of the fan body shell 11. When the axial flow fan 12 blows air upward, the external air enters the fan body shell 11 through the air inlet 16 under negative pressure. After entering the fan body shell 11, the external air quickly mixes with the water mist deodorizing liquid. During the upward process, the air pressure is increased by passing through the constriction formed by the conical guide shroud 22. When the air and the water mist deodorizing liquid pass through the constriction, the distance between the water mist molecules decreases, thereby further increasing the degree of contact and mixing with the air.

[0018] Preferably, it also includes a mixer 21, which is disposed inside the main housing 11 of the fan and located between the conical guide shroud 22 and the axial flow fan 12. The mixer 21 includes an arc-shaped guide wall with a diameter larger than the side length of the upper port of the conical guide shroud 22. When air and water mist deodorizing liquid pass through the conical guide shroud 22, they are accelerated under wind pressure and quickly impact the mixer 21, further compressing the spacing between the water mist particles of the deodorizing liquid and improving the mixing and contact effect with the air.

[0019] Preferably, the mixer 21 includes an auxiliary fixing frame 17, a rotating shaft 18, a flow guide shroud 19, and flow guide vanes 20. The auxiliary fixing frame 17 is fixed to the top circular hole of the fan body housing 11 for fixing the rotating shaft 18. A bearing is provided at the lower end of the rotating shaft 18. The flow guide shroud 19 is rotatably mounted on the lower end of the rotating shaft 18 via the bearing. The rotating shaft 18, flow guide vanes 20, and circulation pipe 24 are coaxially arranged (e.g., ...). Figure 4 When the air and deodorizing liquid rise, they quickly impact the lower end face of the flow guide 19.

[0020] Preferably, the flow guide 19 has a hollow hemispherical structure (see...). Figure 4 , 6 When the air carrying the deodorizing liquid mist rises and contacts the guide shroud 19, it forms a descending airflow under the comprehensive airflow guidance of the top wall plane of the fan body shell 11, and forms a vortex swirling along the inner circular wall of the guide shroud 19. This further enhances the thorough mixing of air and deodorizing liquid mist. Then, under the blowing action of the axial flow fan 12, the treated air is discharged. Compared with the existing technology where the airflow directly passes through the equipment upwards, this device has a better mixing and contact effect between air and deodorizing liquid.

[0021] Preferably, to further improve the mixing effect and make the airflow smoother and more orderly as it passes over the outer side of the guide shroud 19, guide vanes 20 are fixedly provided at annular intervals on the outer circular wall of the guide shroud 19. When the airflow rises and acts on the guide vanes 20, it causes the guide shroud 19 to rotate, spirally guiding the rising airflow (e.g., ...). Figure 6 ).

[0022] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
