Second weight linear meter 228 is made up of steel plate or round steel, and is arranged on outside discharger slip awaing tube 230.Second weight linear meter 228 End is connected with the end vertical of the second rotating shaft 224;And the second weight linear meter 228 is set in obtuse angle with the second dust block board 222, i.e., Second weight linear meter 228 and the distribution of the second dust block board 222 are positioned at the both sides of the second rotating shaft 224.When the second dust block board 222 is in level During state, the second weight linear meter 228 and the angle in the discharging direction of discharger slip awaing tube 230 are acute angle.
The second limited block 226 is provided with the inwall of 4th steel plate 238, its bottom is provided with rubber blanket, the second limited block 226 height with the second rotating shaft 224 on discharger slip awaing tube 230 is basically identical.Second dust block board 222 is in the second weight linear meter 228 Bottom under Action of Gravity Field with the second limited block 226 abuts.
In use, the dust that dust arrester installation 200 is collected into is gathered on the first dust block board 212 in elephant trunk.Match somebody with somebody first Under the Action of Gravity Field of weight bar 218 and balancing weight 219, the first dust block board 212 keeps abutting with the first limited block 216, first gear ash Plate 212 blocks discharger slip awaing tube 230 so that dust will not leak down;When dust aggregation is more, under the Action of Gravity Field of dust, First dust block board 212 rotates around first rotating shaft 214, and so as to which the passage of discharger slip awaing tube 230 be opened, dust drops into second gear ash On plate 222, meanwhile, the first dust block board 212 is closed.Second dust block board 222 is opened under dust Action of Gravity Field, and dust is discharged. In whole process, it is closed due at least one in the first dust block board 212 and the second dust block board 222, prevents air Entered out of discharger slip awaing tube 230 in smoke evacuation system 100, thereby may be ensured that system steady operation.May be used also according to actual conditions Suitably to increase or decrease the quantity of balancing weight 219.
Because the bottom of the first limited block 216 and the second limited block 226 is provided with rubber blanket, therefore when the first device for discharging 210 and second device for discharging 220 when closing, it will not produce larger noise, and can effectively small gap.
As shown in Figure 1, Figure 3 and Figure 4, dust arrester installation 200 also includes water sprinkler 240, and water sprinkler 240 is arranged on discharger slip awaing tube 230 It is interior, and positioned at the discharging opening of discharger slip awaing tube 230.Water sprinkler 240 includes washing head 241, water pipe 242, connecting tube 243, ball valve 244 With connecting rod 250.The cooperation section of washing head 241 and discharger slip awaing tube 230 is provided with connecting tube 243, the outer surface of connecting tube 243 is set Screw thread is equipped with, the position that discharger slip awaing tube 230 installs washing head 241 is provided with screwed hole, and connecting tube 243 coordinates with screwed hole and connected Connect.Protective cover 246 is additionally provided with washing head 241, protective cover 246 is formed by steel plate bending, and it covers on the top of washing head 241 It is fixed on washing head 241 or on the tube wall of discharger slip awaing tube 230.
The one end of water pipe 242 connects washing head 241, other end connection water source.The ball valve 244 of water pipe 242 is arranged on water pipe 242 On, including switch knob 2442, rotary shaft (not shown) and spheroid (not shown).Switch knob 2442 passes through rotation Axle is connected with bulb, and the rotation of switch knob 2442 drives the rotation of spheroid to realize the switch of ball valve 244.
The one end of connecting rod 250 is be hinged with the second weight linear meter 228, and the other end is be hinged with switch knob 2442.Due to water pipe 242 with Discharger slip awaing tube 230 is fixedly connected, therefore the second weight linear meter 228, connecting rod 250, switch knob 2442, water pipe 242 and discharger slip awaing tube 230 Crank and rocker mechanism is collectively constituted.By reasonably can be designed so that the rotation of the second weight linear meter 228 drives switch knob 2442 are rotated in the range of 90 °, and switch knob 2442 need to be only rotated by 90 ° by the switch of ball valve 244, therefore the second weight linear meter 228 rotation can control the switch of ball valve 244.
When the dust being gathered on the second dust block board 222 is more, in the presence of weight of dust, the second dust block board 222 open, and drive the second rotating shaft 224 to rotate, and the second rotating shaft 224 drives the second weight linear meter 228 to rotate again;In connecting rod 250 Under effect, switch knob 2442 rotates, and ball valve 244 automatically opens up, and the water in water pipe 242 flows to washing head 241 to from second gear The dust fallen on hawk 222 is sprinkled water.When the second dust block board 222 is in the presence of the second weight linear meter 228 and balancing weight 219 During closing, crank screw body performs opposite operation, and ball valve 244 is closed automatically.
Easily make to produce airborne dust in workshop when dust is fallen on belt from discharger slip awaing tube 230, water sprinkler 240 is by ash Dirt watering can be to efficiently reduce airborne dust.Also, the water sprinkler 240 that the present embodiment provides can be in dust dropping process certainly Dynamic that dust is sprinkled water, this can both ensure that watering uniformly can be with using water wisely.Protective cover 246 can prevent dust from falling on watering On first 241, to avoid blocking the apopore of washing head 241.
It should be noted that the present embodiment is preferred embodiment, in other embodiments, the He of ball valve 244 can be not provided with Connecting rod 250;Or in other embodiments, protective cover 246 or rubber blanket can also be not provided with;Or in other embodiments, Balancing weight 219 or bearing can also be not provided with.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for For those skilled in the art, the utility model can have various modifications and variations.It is all in spirit of the present utility model and former Within then, any modification, equivalent substitution and improvements made etc., it should be included within the scope of protection of the utility model.
