Detailed Description
The following further describes embodiments of the present invention with reference to the drawings.
The fog gun of the present invention is applied to a dust suppression vehicle, and is used for spraying water mist into air to achieve the effects of suppressing dust and reducing dust, as shown in fig. 1 to 6. The fog gun comprises an air duct 11, a guide cone 7, namely a guide column, a fan, a guide plate 9 and the like, wherein the air duct 11 is of a cylindrical structure with an axis extending in the front-back direction, the guide cone 7 is arranged in the air duct 11 in a penetrating manner and is coaxially arranged with the air duct 11, and an annular space formed between the air duct 11 and the guide cone 7 forms a circulation channel for air supply flow to pass through. In this embodiment, air duct 11 and guide cone 7 are relatively fixed through guide plate 9, a plurality of guide plates 9 extending in the front-rear direction are arranged in the annular space between air duct 11 and guide cone 7 along the circumferential direction at intervals, the outer side of guide plate 9 is welded and fixed with the inner wall of air duct 11, and the inner side is welded and fixed with the outer peripheral surface of guide cone 7, so that guide plate 9 and air duct 11 can be coaxially assembled and relatively fixed.
The fan is arranged at the front end of the guide cone 7, the guide cone 7 is a cylindrical structure which is through from front to back, the motor 6 in the fan is installed in the guide cone 7, namely, the front section part of the inner hole of the guide cone 7 forms an accommodating cavity for installing the motor 6, meanwhile, the hub of the fan is rotatably arranged on the motor shaft, the outer diameter of the hub is consistent with the outer diameter of the front end of the guide cone 7, the guide cone 7 and the cylindrical surface of the hub can be in equal-diameter transition, and the air flow efficiency is greatly improved. A bearing seat 5 is arranged in the guide cone 7 at the position of the motor shaft, the motor shaft is supported by a bearing 4, and the hub and the motor shaft are relatively fixed. The front side of the hub is connected with a flow guide cover 2, and a protective screen 1 is covered at the air inlet of the air duct 11.
In the actual working process, the motor 6 drives the blades 3 on the hub to rotate, so that the gas at the air inlet of the air duct 11 is accelerated, the gas forms a rotary airflow passing through an annular space between the guide cone 7 and the air duct 11, the original rotary airflow is converted to an axial airflow through the guide effect of the guide plate 9, and then the high-flow-rate airflow is ejected outwards through the air outlet of the air duct 11. Meanwhile, a plurality of atomizing nozzles 12 are further arranged at one end of the air outlet on the air duct 11, and the mist outlet positions of the atomizing nozzles 12 are located within the outer contour of the air outlet column of the air duct 11, so that the water mist can be driven to achieve the purpose of long-distance spraying when the high-flow-rate air flow passes through the mist outlet positions of the atomizing nozzles 12.
For the guide plate 9, when the rotating airflow collides with the guide plate 9 for guiding, due to the pressure difference problem, a component vortex on a certain radial section is generated on one side of the plate surface close to the guide plate 9, which will cause a vortex component on the above-mentioned cross section generated in the flow channel inside the guide plate during the collision process of the rotating airflow and the guide plate, and until the air outlet can not be eliminated or reduced, the circumferential component of the vortex after the airflow flows out of the air cylinder is spread outwards, thereby increasing the attenuation speed of the airflow in the atmosphere, and further, the airflow transportation at a longer distance can not be realized, and further, the injection effect is affected, in order to avoid or reduce this problem, in the embodiment, the guide plate 9 is provided with vortex elimination holes penetrating through the plate surfaces on both sides, two airflows with opposite directions can be subjected to convection impact by the arrangement of the vortex elimination holes, and the vortex, and further, the gas flowing speed when the rotary airflow is changed into the axial airflow is ensured, and the spraying distance of the water mist is further improved.
Of course, in order to ensure the uniformity of the flow of the airflow at the position corresponding to the vortex elimination hole when the component vortex is reduced, in this embodiment, the vortex elimination hole is a long hole extending along the axial direction of the air duct 11, so that the pressure of the airflow at each position in the vortex elimination hole along the extending direction can be ensured to be substantially consistent, and thus the uniformity of the airflow flow can be ensured. The structure is simpler.
Meanwhile, in order to further ensure the uniformity of the airflow, in this embodiment, the side wall of the vortex elimination hole close to the air duct 11 is parallel to the corresponding side wall of the air duct 11. The arrangement can match the flow path of the axial airflow in the air duct 11, so that the airflow flows more uniformly.
Furthermore, in order to facilitate processing and adapting to the size of the conical surface section of the air duct 11, in this embodiment, the vortex elimination holes are parallelogram holes, and the widths of the positions of the vortex elimination holes along the extending direction are all the same, which is favorable for the consistency of the vortex elimination effect.
In this embodiment, in order to ensure the vortex eliminating effect and the supporting effect on the guiding cone 7, there are two vortex eliminating holes, and the two vortex eliminating holes are arranged on the guiding plate 9 at intervals along the axial direction and are respectively a front vortex eliminating hole 8 and a rear vortex eliminating hole10, the distance between the front end of the guide plate 9 and the front side wall of the front vortex elimination hole 8 is defined as a1The front-rear length of the front vortex elimination hole 8 is a2The distance between the rear side wall of the front vortex elimination hole 8 and the front side wall of the rear vortex elimination hole 10 is a3The length of the rear vortex elimination hole 10 is a4The distance between the rear side wall of the rear vortex elimination hole 10 and the rear end of the guide plate 9 is a5Then a is1、a2、a3、a4、a5Satisfy the relationship of (a)1:a2:a3:a4:a5=0.5:1:0.8:1: 1.5. The width of the rear end of the guide plate 9 is defined as b1The width of the rear vortex elimination hole 10 is b2The width of the front vortex elimination hole 8 is b3The width of the front end of the guide plate 9 is b4Then b is1、b2、b3、b4Satisfy the relationship of (b)1:b2:b3:b4=6.8:1:1.6: 9.1. The distance between the front eddy eliminating hole 8 and the bottom of the front end of the guide plate 9 is defined as h1The distance between the rear vortex elimination hole 10 and the bottom of the rear end of the guide plate 9 is h2Then h is1=h2=b4/3. Set up like this and can guarantee that the vortex hole that disappears have the maximize the vortex effect that disappears outside, can also guarantee the overall structure intensity of guide plate 9, satisfy the required intensity of the support dryer 11 of guide plate 9 and water conservancy diversion awl 7. The eddy eliminating holes can reduce component eddy of airflow in the air duct 11 on the radial section, reduce the divergence angle of the airflow at the outlet, reduce the turbulence coefficient and increase the jetting range. And the relationship between the divergence angle of the air flow and the turbulence factor is: s = (0.48/V)m∙V0-0.147)∙d0A; tg α =3.4 a. Wherein S is the jet distance, V0Initial gas velocity, VmIs the axial wind speed at a distance S, d0The diameter of the airflow at the outlet of the cylindrical surface, a is the turbulence coefficient, and alpha is the airflow diffusion angle. As can be seen from the above relationship, reducing the gas flow divergence angle facilitates reducing the turbulence factor, thereby increasing the jet distance. The provision of the swirl-reducing holes enables the diffusion angle of the gas flow at the position where component vortices are generated on the radial cross-section to be reduced, and thus the turbulence factor can be reduced, thereby increasing the jet flow distance. The water mist is driven by the airflow to be sprayed to a far position. At the same time, fromThe larger the flow velocity of the air flow on the side closer to the air duct 11, the more the vortex-eliminating holes are formed on the side closer to the inner wall of the air duct 11, so that the vortex-eliminating effect can be realized as much as possible.
For the guide cone 7, it has a column section and a cone section with gradually decreasing diameter connected with the column section, the guide plate 9 is fixedly supported on the cone section, so the column section will extend forward and form a cantilever structure, the motor 6 of the fan is installed at the front end of the cantilever structure, and the motor shaft extends forward. Set up like this and compare in the structure that supports guide cone 7 or motor casing through guide plate 9 among the prior art, can keep away from guide plate 9 setting forward with the front end of guide cone 7, just so can guarantee to have enough far-away axial interval between blade 3 of fan and the guide plate 9, noise when being favorable to reducing the flow of air current in dryer 11.
Meanwhile, for the diversion cone 7, in this embodiment, a through hole 14 penetrating through the inner and outer side walls of the diversion cone 7 is formed in the side wall of the diversion cone 7 located behind the fan, and the through hole 14 is communicated with the rear end outlet of the diversion cone 7, that is, the through hole forms an air inlet, the rear end outlet forms an air outlet, the through hole is communicated with the rear end outlet to form an air flow compensation channel for the air flow to pass through, so that when the fan operates, a part of the air flow can enter the diversion cone 7 through the through hole 14 and is discharged from the rear end outlet 13 of the diversion cone 7 through the guidance of the inner wall surface of the diversion cone 7. This small part air current can compensate the pressure of air outlet department, can reduce the pressure gradient at guide cone 7 rear end portion, reduces the high-speed air current in the annular space between guide cone 7 and the dryer 11 and towards the rear end terminal surface gathering backward flow condition of guide cone 7, increases the homogeneity of dryer 11 export air current. As shown in fig. 5, when there is no through hole and the rear end opening 13 is not communicated, the airflow velocity at the rear end of the air duct is relatively turbulent and approaches to the position of the rear end of the guide cone 7 to form a vortex; when the rear end opening 13 is communicated with the through hole 14, as shown in fig. 6, the air flow velocity at the rear end of the air duct is relatively uniform and the air flow velocity is relatively concentrated.
Furthermore, the through hole 14 is formed in the side wall of the diversion cone 7 corresponding to the installation position of the motor 6, so that in the working process of the motor 6, heat generated by the working of the motor 6 can be taken away by airflow circulation, and a certain heat dissipation effect is achieved on the motor 6.
In other embodiments, the motor may be disposed behind the guide cone, so that the air inlet may be selectively disposed on the rear end surface of the guide cone; the cylindrical front opening of the guide cone can be directly formed into an air inlet.
The embodiment of the sanitation vehicle comprises a vehicle body and the fog gun arranged on the vehicle body, wherein the structure of the fog gun is the same as that of the embodiment of the fog gun, and the detailed development is omitted.
