The specific embodiment
Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model electric dust absorption device comprises main frame 11, the side of square main frame 11 is provided with the suction inlet 11a and the installing port 11b that charging assembly 12 and dust suction subassembly 13 are installed of dusty gases such as sucking water-soluble mist of oil and weld fumes, the top outlet 11c that discharges clean gas that also is provided with of main frame 11.The pressure fan (not shown) that main frame 11 inside are equipped with charging assembly 12 that the dust in the dusty gas is charged successively in suction inlet 11a one side, collect the dust suction subassembly 13 that is recharged dust and dusty gas is sucked and clean gas is discharged from outlet 11c from suction inlet 11a.Installing port 11b place is provided with door 14, and door 14 can free folding, and door 14 is provided with to charging assembly 12 and the high-tension first high voltage supply insulator 15 is provided and provides the high-tension second high voltage supply insulator 16 to dust suction subassembly 13.And, also be provided with first control part that in the control first high voltage supply insulator 15, the second high voltage supply insulator 16, can detect unusual condition and judge the output control signal on the door 14.Main frame 11 rear portions are provided with second control part 17 of the start and stop of control device.
As shown in Figure 2, the profile of dust suction subassembly 13 is square, the upper and lower of dust suction subassembly 13 is respectively equipped with first guide plate 21 and second guide plate 22, the right and left of dust suction subassembly 13 is respectively equipped with first side plate 23 and second side plate 24, dust suction subassembly 13 inside are provided with a plurality of grounding electrode plate 25 and electrode plate with high voltage 26, grounding electrode plate 25 and electrode plate with high voltage 26 separately relatively and keep certain intervals arranged in a crossed manner, grounding electrode plate 25 be shaped as tabular.Grounding electrode plate 25 is made by the iron with high conductivity, aluminium, stainless steel and other metal materials, such as in charging assembly 12, dusty gas being filled positive electricity, and the minus earth of power supply then.If the resistance height of grounding electrode plate 25, the electric charge that then is recharged dust can be put aside on grounding electrode plate, reduces the electric-field intensity of grounding electrode plate 25 and electrode plate with high voltage 26, and pick-up performance is significantly descended.Therefore, the surface of grounding electrode plate 25 must be coated the high electrically-conducting paint of electric conductivity, or use the high synthetic resin material of electric conductivity to make grounding electrode plate 25, increase electric-field intensity with this.
Electrode plate with high voltage 26 in this installation example is made by the half insulation resin material.As shown in Figure 3, electrode plate with high voltage 26 be provided be mainly used in collect the collection unit 26a be recharged dust, for the fixed intervals that keep 26 of electrode plate with high voltage and at two side-prominent integrated washer portion 26b, and the jack 26c of the following slotting power supply axle usefulness that will illustrate, collection unit 26a is shaped as tabular.
As shown in Figure 4 and Figure 5; in the jack 26c of electrode plate with high voltage 26, be embedded with the tubulose protective sleeve 27 that the half insulation resin material identical with electrode plate with high voltage 26 made; the number of tubulose protective sleeve 27 is determined that by the number of the power supply axle 28 that its interpolation tubulose protective sleeve 27 covers the periphery of this power supply axle 28.At this moment, because the both sides of electrode plate with high voltage 26 are provided with washer portion 26b, each washer portion 26b fits tightly and can make electrode plate with high voltage 26 keep equal intervals.The sealing ring 29 that is provided with flange 29a in the outside of electrode plate with high voltage 26 is embedded in the tubulose protective sleeve 27, and chimeric place seals with an O type circle 30.On the extended line of power supply axle 28, will provide high-tension high voltage supply insulator 31 to be fixed on second side plate 24 to power supply axle 28.High voltage supply insulator 31 is provided with on the partition wall 33 of second side plate 24 by utilizing packing ring 32 to be fixed on, and isolates with the throughput of this and dusty gas.
Be provided with an insulator 34 in the middle of the partition wall 33, insulator 34 has the first installing hole 34a and the second installing hole 34b, a plurality of fin-shaped parts 34c that contain in insulator 34 periphery embeddings, chimeric sealing ring 29 on the first installing hole 34a, and chimeric place is with the 2nd O type circle 35,36 sealings of the 3rd O type circle.And power supply axle 28 is fixed on the insulator 34 by insulation board 37 usefulness conduction screw 38, connects by power spring 39 between conduction screw 38 and the high voltage supply insulator 31.And high voltage supply insulator 31 also is connected with the second high voltage supply insulator 16 on the door 14 that is installed in main frame 11 simultaneously.
According to above-mentioned structure, charging assembly 12 is transfused to voltage by the first high voltage supply insulator 15, and dust suction subassembly 13 is transfused to voltage by the second high voltage supply insulator 16.And the second high voltage supply insulator 16 passes through high voltage supply insulator 31, power spring 39, conduction screw 38, power supply axle 28 and tubulose protective sleeve 27 to electrode plate with high voltage 26 input voltages.Therefore, in charging assembly 12, produce corona discharge in the ionizing radiation (not shown) and between to electrode; In dust suction subassembly 13, produce electric field at high pressure electroplax 26 and 25 of grounding electrode plate.In this state, the running of pressure fan (not shown), dusty gas flows towards the A direction of Fig. 1, is subjected to corona discharge in charging assembly 12, and the dust in the dusty gas is recharged.Be recharged between the electrode plate with high voltage 26 and grounding electrode plate 25 that dust then flows into dust suction subassembly 13, the grounding electrode plate 25 with opposite polarity is caught.Then, the clean gas of having removed dust is discharged towards the B direction from outlet 11c and is flowed out.
Because electrode plate with high voltage 26 is made by the half insulation resin material with packing ring 32; tubular protection tube 27 is by making with electrode plate with high voltage 26 identical materials; even contain moisture and electric conductivity dust because of containing mist of oil, water-soluble mist of oil and welding dust etc. in the dusty gas; the electric charge that the resistance of half insulation resin material also can be controlled electrode plate with high voltage 26 moves; therefore between electrode plate with high voltage 26 and grounding electrode plate 25, spark can be do not produced, dust collection efficiency can be do not reduced yet.In addition; throughput at dusty gas; because power supply axle 28 is covered by electrode plate with high voltage 26 and the tubulose protective sleeve 27 made by half insulation resin material or equal material material; and tubulose protective sleeve 27 is sealed by an O type circle 30 and the 2nd O type circle 35, the 3rd O type circle 36 with insulator 34; therefore moisture and conductive liquid can not invaded its inside; can not produce big electric current owing to revealing on the way, the generation of pre-sparkproof unchangeably for a long time dust collection efficiency can not occur and descend.And partition wall 33 is isolated the high voltage supply insulator 31 and the throughput of dusty gas fully, can not adhere to moisture and electric conductivity dust on the high voltage supply insulator 31, can not produce the defective insulation of high voltage supply insulator 31.
Though more than described the specific embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these embodiments.Therefore, protection domain of the present utility model is limited by appended claims.
