Abstract
The invention discloses a novel air filter and belongs to the technical field of agricultural machinery. The novel air filter comprises an air filter and a prefilter, wherein the air filter comprises an air filter shell and a main filter element arranged in the air filter shell; and a prefilter shell is integrated with the air filter shell. According to the invention, the prefilter and the air filter are combined, so that the novel air filter has high air input, low intake resistance, compact structure and small installation space and is widely applied to the agricultural machinery.
Description
Technical field
The present invention relates to agricultural machinery technological field, relate in particular to a kind of air-strainer.
Background technique
Raising along with the gas handling system requirement; The used diesel engine air inlet system of supporting farm machinery (like tractor, harvest machinery etc.) becomes increasingly complex; Under the prerequisite that guarantees the air inlet turbidity test, also have higher requirements for aspects such as the boundary dimension of empty filter, property easy for installation, maintainings.
Present common normal air filter system, most suction tude that adopt connect this complex structure between prefilter and the empty filter; Weight is heavier, and it is steadily vertical to require the mounting point to need, or has fixing; Required installing space is big, has defectives such as connecting link is many, intake resistance is big.
Summary of the invention
Technical problem to be solved by this invention is: a kind of new air filter is provided, and prefilter and empty filter are combined, and air inflow is big, and intake resistance is little, and compact structure, installing space are little.
For solving the problems of the technologies described above; Technological scheme of the present invention is: new air filter; Comprise the sky filter; Said empty filter comprises sky filter housing and the main filter core that is installed in the said empty filter housing, and said new air filter also comprises prefilter, and described prefilter housing and empty filter housing are set to one.
As a kind of improvement, be provided with safe filter core in the said empty filter housing, it is inner that said safe filter core is positioned at main filter core.
As further improvement, be provided with blade ring in the said empty filter housing, said blade ring is arranged at the periphery of said main filter core.
Correct one's mistakes as a kind of, be provided with safe filter core in the said empty filter housing, said safe filter core is connected with main filter core, and according to airflow direction, said safe filter core is arranged at the downstream of said main filter core.
As further improvement, said prefilter is an eddy flow tubular type prefilter.
As further improvement, said prefilter is the rotator type prefilter.
After having adopted technique scheme; The invention has the beneficial effects as follows: because prefilter housing and empty filter housing are set to one; Realized the integral type combination of empty filter and prefilter; Form a complete air filtering system, realized single air-strainer realization multi-staged air filtering function, and brought following benefit:
(1), compact structure, installing space is little, has alleviated weight, has reduced cost, the convenient installation;
(2), safeguard easy to usely, reduced maintenance man-hours, thereby can improve user's economic benefit;
(3), because air is directly got into by suction port, through pre-flock and smart filter, discharge then from the air outlet, saved medium tache, reduced resistance of air, increased air inflow;
(4), adopt the multistage filtering performance better, can prolong engine air filter filter core work timing, prolong the working life of motor, save the equipment downtime maintenance time.
Owing to also be provided with safe filter core and blade ring in the empty filter housing, further increased filtering effect, improved the air-filtering quality.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention one;
Fig. 2 is the structural representation of the embodiment of the invention two;
Among the figure: 1, prefilter, 11, the prefilter housing, 2, empty filter, 21, empty filter housing, 22, main filter core, 23, safe filter core, 24, blade ring, 3, suction port, 4, the air outlet.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Embodiment one:
As shown in Figure 1; A kind of new air filter comprises sky filter 2, and said empty filter 2 comprises sky filter housing 21 and the main filter core that is installed in the said empty filter housing 21; Said new air filter also comprises prefilter 1; Described prefilter housing 11 is set to one with empty filter housing 21, and set-up mode can be to be fixedly installed togather, and also can be to be one through different molding mode once-throughs such as injection moulding or punching presses; Described new air filter comprises a suction port 3 and an air outlet 4; Be provided with safe filter core 23 and blade ring 24 in the said empty filter housing 11, said safe filter core 23 is positioned at main filter core 22 inside, and said blade ring 24 is arranged at the periphery of said main filter core 22.During work, gas gets into from suction port 3, through pre-flock, main filter core 23, safe filter core 22, and 4 discharges from the air outlet then, the clean air that process is filtered enters into the turbosupercharger of motor or motor again through pipeline.Wherein, said prefilter 1 is preferably eddy flow tubular type prefilter, and said prefilter 1 is preferably the rotator type prefilter.
Embodiment two:
Shown in Fig. 2 is common; A kind of new air filter, its structure and embodiment one are basic identical, and its difference is; Be provided with safe filter core 23 in the said empty filter housing 11; Said safe filter core 23 is connected with main filter core 22, and according to airflow direction, said safe filter core 23 is arranged at the downstream of said main filter core 22.
The present invention is not limited to above-mentioned concrete mode of execution, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within protection scope of the present invention.
