Abstract

The utility model discloses a pretreatment device for combustion air entering internal-combustion engines. The utility model has the purpose that on the basis of a strainer, a first level permanent magnet core and two levels permanent magnet elements are increased for separating metallic substance in the air. The pretreatment device for combustion air entering internal-combustion engines comprises an air inlet magnetic assembly and an air outlet magnetic assembly which are respectively assembled on the top and the bottom parts of a crust. The strainer and a magnetic filter element assembly are arranged in the crust and a cover is arranged on the crust. The utility model has the advantages of convenient assembly, simple structure, convenient cleaning and simple technic art, can produce carbon deposit in a cylinder, can prolong service life, can decrease maintenance, and can achieve the goal of saving energy. The pretreatment device for combustion air entering internal-combustion engines can be used for various internal-combustion engines.

Description

Three-slaged magnetic air cleaner

The utility model is a kind of to entering the pre-treater of combustion in IC engine air.

The prior art of this technical field, at home and abroad contrast is identical substantially on the structure of air-strainer, and just filter screen density has difference, because the each department physical quantity of atmosphere is unlikely identical, does not also reach the general purpose of various places environment.Be mixed in the cylinder that dust in air impurity enters internal-combustion engine, under 2000～2700 ℃ of high temperature actions, will melt, become liquid, mix forming the carbon iron compound with nonmetallic inclusion, and be attached to formation carbon distribution thing cylinder in by the solid metal particle.Iron content 80% wherein after measured, this will accelerate cylinder wear.If can before air enters cylinder, the metallics that contains in the air be come out with magnetic separation, just do not produce or produce less the carbon distribution thing.

The purpose of this utility model is on the basis of filter screen, adds an improvement again, increases the three lines of defence, and promptly one-level permanent magnetism filter core and secondary permanent magnetic unit come the metallics in the separation of air, reach to purify air.

The utility model mainly is by suction port and air outlet magnet assembly, is contained in the upper and lower of shell relative position respectively, and filter screen and magnetic element kit are cased, with wing nut and the fastening loam cake of long spiro nail.

The utility model has the advantages that the structure that do not change internal-combustion engine, easy to assembly, simple in structure, cleaning is convenient, technical matters is simple, can reach from the physical quantity of atmosphere of various places environment, to extract and separate the trace meter material, thereby make and produce the carbon distribution thing in the cylinder less, increase the service life, reduce maintenance, and reach the purpose of energy saving.

Elaborate below in conjunction with accompanying drawing:

Fig. 1 represents that the master of three grades of air-strainer of magnetic looks generalized section.

The magnet assembly 14 main generalized sections of looking of the suction port in Fig. 2 presentation graphs 1.

Generalized section is looked on the right side of Fig. 3 presentation graphs 2.

The schematic top plan view of magnetic element kit 8 in Fig. 4 presentation graphs 1.

C launches enlarged diagram to the part in Fig. 5 presentation graphs 4.

Fig. 6 represents that the master of circlip for hole 13 looks schematic representation.

Air outlet magnet assembly 1 and suction port magnet assembly 14 in

shell

2 and 11, wherein are shaped on two grooves 12 respectively respectively among Fig. 1, are contained in two circlip for holes 13 again.

Shell

2 and 11 is contained in the upper and lower of shell 9 relative positions respectively, and mating holes 3 and 10.Loam cake 4 is arranged on the shell, and the bottom has at the bottom of the shell 16 and hole 15, and wing nut 5 and long spiro nail 6 are equipped with in its center, and filter screen 7 and magnetic element kit 8 also are equipped with in the inside of shell 9.

The center of Fig. 2 middle shell 19 is shaped on endoporus 18, one ends and is shaped on seam 17 and hole 23, and three magnetic elements 21 and two packing rings 22 and a back-up ring 20 wherein are housed.

Be shaped on four semicircle orifices 24 in Fig. 3 middle shell 19, in magnetic element 21, be shaped on ring fan groove 25 and center hole 26.

Between the magnetic filter core piece 27 dottle pin 28 is housed among Fig. 4, from C to seeing that its structure is the prismatic hole 29 Fig. 5.

Best way of the present utility model is that air outlet magnet assembly 1 is identical with the structure of suction port magnet assembly 14 among Fig. 1, and its

shell

2 and 11 is made circle.16 usefulness low-carbon (LC) steel welding assemblies at the bottom of

shell

2,9,11 and the shell, also available plastic injection-moulded one-tenth is whole.Loam cake 4 can be made with low carbon steel or plastics.According to the space of installing, shell 9 can be made into circular or square or hexagon, and 16 also use respective shapes at the bottom of its loam cake 4 and the shell.2～4 of 16 edges holes at the bottom of the shell, one of them should stagger with shell 11 and be convenient to install.

Housing 19 among Fig. 2 adopts the low-carbon (LC) steel to make circle, and also available industrial plastic ABS is injection molded.Ring washer 20 and packing ring 22 adopt low carbon steel, and its thickness is 1.5～2.5 millimeters.Magnetic element 21 adopts the ferrite permanent-magnet material, and its magnetic field peak value is 10～50MT(, million spies), form through the stamping of powder sintering.

The material requirements of magnetic filter core piece 27 is identical with magnetic element 21 among Fig. 4, becomes long prismatic hole 29 among Fig. 5 through molding sintering.Magnetic filter core piece 27 is made 6～8, and its profile and size should adapt with shell 9.Filter screen 7 adopts the galvanized wire filter screen, coils 2～5 layers and is contained in the magnetic element kit 8.

Air enters suction port magnet assembly 14 from suction port A, passes through magnetic element kit 8, filter screen 7 and air outlet magnet assembly 1 again, by three grades of filtering air again from entering the cylinder of internal-combustion engine after air outlet B enters Carburetor and gasoline mixes.

When the dust impurity of cleaning in the filter cleaner, back out wing nut 5, take out filter screen 7 and magnetic element kit 8, also to take out three magnetic elements 21 in

shell
