Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
An air filter device for a work machine and a work machine according to the present invention will be described below with reference to fig. 1 to 11.
As shown in fig. 1, the present embodiment provides an air filter device for a work machine, the air filter device 100 including: a prefilter 12, an air cleaner 13, and a first air pipe 14; the mounting assembly 11 is adapted to be mounted to the outside of the upper body of the work machine; the prefilter 12 and the air cleaner 13 are respectively arranged on the upper side of the mounting assembly 11, the air outlet end of the prefilter 12 is opposite to the first end 131 of the air cleaner 13, and the second end 132 of the air cleaner 13 is arranged towards the outer side of the working machine; wherein the second end 132 of the air cleaner 13 serves as a maintenance end; one end of the first air pipe 14 communicates with the air outlet end of the prefilter 12, and the other end of the first air pipe 14 communicates with the first end 131 of the air cleaner 13.
Specifically, in the present embodiment, by integrating the prefilter 12 and the air cleaner 13 on the upper side of the installation assembly 11 and optimally arranging the positions and attitudes of the prefilter 12 and the air cleaner 13, the integration level of the whole set of air filtering device 100 is ensured, the inflection point and the length of the first air pipe 14 arranged between the prefilter 12 and the air cleaner 13 are effectively reduced, the intake air amount is ensured while the intake resistance is reduced, and the maintenance of the equipment are facilitated.
Here, the prefilter 12, the air cleaner 13, and the first air pipe 14 shown in the present embodiment are uniformly arranged on the installation component 11, and the present embodiment can install the installation component 11 as a support, so as to realize modular installation of the air filter device 100 on the upper vehicle body of the working machine, which is convenient and fast, and can reduce occupation of effective space on the working machine as much as possible.
Meanwhile, the arrangement of the prefilter 12 and the air filter 13 ensures that the trend of the first air pipe 14 is smooth, the pipeline is short, on-way resistance and local resistance are reduced, the air inflow of the engine is increased, and the operation performance of the whole vehicle can be maintained under severe working conditions of the operation machine.
Compared with the prior art that an operator maintains the air filter device in a high-temperature indoor environment, since the installation component 11 is installed on the outer side of the upper vehicle body of the working machine and the second end 132 for maintenance on the air filter 13 faces the outer side of the upper vehicle body, the operator can conveniently open the second end 132 of the air filter 13 on the outer side of the upper vehicle body and take out the filter element of the air filter 13 so as to perform maintenance operation of the air filter 13 outdoors, thereby ensuring the comfort of the working environment of the operator during maintenance, reducing the limitation of the limited indoor space on the maintenance operation and improving the efficiency of the maintenance operation of the air filter device 100 to a certain extent.
Based on the solution shown in the above embodiment, the air filtering device 100 shown in the present embodiment further includes a second air pipe 15, and the third end 133 of the air cleaner 13 is used as an air outlet end, and the third end 133 is communicated with one end of the second air pipe 15, and the other end of the second air pipe 15 is communicated with the turbocharger in the engine compartment 300; the second end 132 of the air cleaner 13 is opposite to the third end 133 of the air cleaner 13 in the axial direction of the air cleaner 13, and the first end 131 of the air cleaner 13 is provided on the side surface of the air cleaner 13.
In actual operation, the air containing dust from the outside is filtered by the prefilter 12 and the air cleaner 13 in this order, based on the driving force provided by the turbocharger, and then is sent to the engine through the turbocharger.
Here, in the present embodiment, a plurality of prefilters 12 may be provided to face each other with respect to the air cleaner 13, or a plurality of prefilters 12 may be communicated with one air cleaner 13 through the first air pipe 14, which is not particularly limited, but the intake air amount of the engine should be ensured as low as possible under the condition of low intake air resistance, so that the intake air resistance of the air filter device 100 is matched with the intake air amount.
Among them, the prefilter 12 shown in the present embodiment is preferably an oil bath type prefilter, and the air cleaner 13 is preferably a two-stage dry type air cleaner, in order to secure the air cleaning effect.
In order to ensure the gas conveying effect, flexible rubber hoses can be selected for the first air pipe 14 and the second air pipe 15 in the embodiment. In this embodiment, one end of the first air pipe 14 is connected to the air outlet end of the prefilter 12 through a clamp, the other end of the first air pipe 14 is connected to the air inlet end of the air filter 13 through a clamp, and one end of the second air pipe 15 is connected to the air outlet end of the air filter 13 through a clamp.
In some embodiments, as shown in fig. 1 and 10, the present embodiment may further provide a sprayer 122 on the rain cap 121 of the prefilter 12, where the sprayer 122 is used to spray water mist at and near the air intake end of the prefilter 12.
Here, in this embodiment, by controlling the atomizer 122 to spray the water mist near the air inlet end of the prefilter 12, on one hand, the water mist sprayed by the atomizer 122 is beneficial to reducing the air inlet temperature of the prefilter 12, improving the air density, and further improving the engine performance, and on the other hand, the water mist sprayed by the atomizer 122 condenses dust in the air, so that a part of the condensed dust falls under the action of dead weight, the ash inlet amount of the prefilter 12 is reduced, and the other part of the condensed dust particles with large particle size enter the prefilter 12, thereby being beneficial to improving the dust separation efficiency.
In some embodiments, in order to timely perform anti-blocking early warning on the air filtering device 100, the air filtering device 100 shown in this embodiment is further provided with an air filtering blocking sensor and an early warning module, the air filtering blocking sensor is connected with the early warning module, and the air filtering blocking sensor is installed at an air outlet end of the air filter 13.
Specifically, the air-filter clogging sensor shown in the present embodiment is used to detect the clogging pressure of the air outlet end of the air cleaner 13, and is specifically a pressure sensor known in the art.
Because the turbocharger continuously pumps air from the air outlet end of the air filter 13, when the prefilter 12 and/or the air filter 13 in the air filter device 100 is blocked, the air pressure of the air outlet end of the air filter 13 can be in a negative pressure state, and when the air filter blocking sensor detects that the blocking pressure is greater than a preset value, the early warning module can immediately send out early warning instructions to inform an operator to clean the prefilter 12 and/or the air filter 13.
The early warning module shown in this embodiment may be a display module, an audible and visual alarm or a voice prompt module, which are well known in the art, and is not limited herein.
