Fig. 2 illustrates the use state reference map of the cleaner shown in Fig. 1.
Detailed description of the invention
The technical problem to be solved in the present invention is: four kinds of methods that factory's dedusting is main at present all exist some defects, it is impossible to ideally solve the existing cleaning to factory's dust. The technical thought solved this technical problem that the present invention proposes is: a kind of cleaner of structure, takes into account filtering type process of cleaning and the advantage of spray for dust suppression method simultaneously; Specifically, when dust is less, filtering type process of cleaning is adopted to clear up; When dust is more, spray for dust suppression method is adopted to clear up.
The present invention is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.
As it is shown in figure 1, Fig. 1 illustrates the schematic diagram of the cleaner of the embodiment of the present invention. This cleaner includes the pipeline 1 with air inlet and air outlet, term " upstream " and " downstream " is applied when position relationship between each parts of cleaner is described below, here, " upstream " and " downstream " is to determine according to the flow direction of air-flow in pipeline 1, it is appreciated that, pipeline 1 air inlet is positioned at the upstream of pipeline 1 air outlet, and correspondingly, pipeline 1 air outlet is positioned at the downstream of pipeline 1 air inlet;
Cleaner also includes being arranged on the inwall of pipeline 1 and by the division board 13 of internal for pipeline 1 first passage being separated into top and the second channel of lower section. Second channel inwall protrudes downwards and is formed with holding tank 11; The position being positioned at holding tank 11 upstream of second channel inwall is protruded upward and is formed with locating part 12; This locating part 12 and division board 13 interval are arranged;
Cleaner also includes the projection 16 being positioned at division board 13 upstream position being arranged on pipeline 1 inwall, and this projection 16 offers the first through hole 161; Cleaner also includes being arranged in locating part 12 upstream position and is slidably disposed on the piston 17 of second channel and is connected with piston 17 and stretches slidably the expansion link 18 in the first through hole 161 and be set on expansion link 18 and two ends connect the spring 19 of projection 16 and piston 17 respectively. When spring 19 is in relaxed state, piston 17 contacts with division board 13, and piston 17 is completely plugged by second channel; When piston 17 downstream is slided, between piston 17 and division board 13, it is separated out gap, so that second channel conducting; In the present embodiment, this gap can be increasing. Here, the change in gap is not limited to increasing, and by the design to division board 13 shape, gap can also first become after greatly and diminish or constant.
Cleaner also include being arranged in first passage and occupy the drainage screen 14 in the whole cross section of first passage and be arranged on pipeline 1 air outlet place, for air-flow to be drawn into the fan component 15 of pipeline 1 air outlet from pipeline 1 air inlet.Cleaner also include the first water pipe (not shown) extending in holding tank 11, the first shower nozzle 20 being arranged on the end being in holding tank 11 of the first water pipe and be arranged on the first water pipe, for drive water along first water pipe flowing and from first shower nozzle 20 ejection the first water pump (not shown). Displacement transducer 21 that cleaner also includes the displacement for detecting expansion link 18 and the controller (not shown) being electrically connected with displacement transducer 21 and the first water pump respectively. Controller starts the first water pump to drive water to spray from the first shower nozzle 20 after being used for the alarm signal sent when receiving displacement transducer 21 because of expansion link 18 downstream generation preset displacement.
By technique scheme, when drainage screen 14 is not blocked by dust and fan component 15 brings into operation, air-flow is only by first passage, and can not pass through second channel. Now, the dust entrained by air-flow is only filtered by filtering type process of cleaning. After have accumulated too much dust on drainage screen 14, drainage screen 14 can entirely shut; Along with fan component 15 continues to run with, the space being positioned at piston 17 downstream of second channel can produce negative pressure, thus causing piston 17 downstream, and expansion link 18 also downstream therewith. Now, being separated out gap between piston 17 and division board 13, namely second channel is opened, and air-flow can pass through second channel, and discharges from pipeline 1 air outlet. Meanwhile, when expansion link 18 downstream preset displacement occurs, water can spray from the first shower nozzle 20, the dust swept along by air-flow can stick to waterborne through the first shower nozzle 20, and drop in holding tank 11 together with water, now, the dust in air-flow is filtered by spray for dust suppression method. When fan component 15 quits work, the negative pressure in the space being positioned at piston 17 downstream of second channel disappears, and piston 17 upstream slides under the effect of spring 19, until spring 19 comes back to relaxed state.
Further, fan component 15 includes the support 152 being arranged on pipeline 1 inwall, be rotatably arranged in the blade 151 on support 152, output shaft is connected with blade 151, for the first motor (not shown) of driven vane 151 and be electrically connected with the first motor, for changing the variator (not shown) of blade 151 rotating speed. This fan is existing structure, does not just repeat one by one here. In factory, the different production phases, the dust of generation is different, such as, for ceramics factory, on a production line during the conversion ceramic tile space of a whole page, when needing the base powder changing different colorant, it is necessary to production line is carried out general cleaning, to prevent the base powder being contaminated with in the ceramic tile produced afterwards formerly. When now the density of the dust in air just produces more usually, the soot density in air wants big. Drainage screen 14 in adopting first passage filters the dust in air, and its efficiency is too low, therefore, now, variator just can be adopted to be tuned up by the rotating speed of blade 151, so, it is possible to so that the space being positioned at piston 17 downstream of second channel produces negative pressure. So that piston 17 downstream, and then making second channel open, the dust in air is carried out spray for dust suppression by final realization.
Further, in the present embodiment, the bottom of holding tank 11 offers the first opening, and the outer wall being positioned at holding tank 11 bottom land of pipeline 1 is formed through the cylinder 22 that the first opening connects with holding tank 11, and, holding tank 11 and cylinder 22 constitute U-tube;Holding tank 11 accommodates the water sealed by the first opening. So, the space in holding tank 11 is just separated by with the external world. Meanwhile, pipeline 1 can also be flowed out from cylinder 22 from the water of the ejection of the first shower nozzle 20. It is appreciated that in certain embodiments, it is possible to the volume of holding tank 11 is designed to sufficiently large, and the stopper that cylinder 22 can be blocked the first opening separably by substitutes. When cleaner works, it is possible to the first opening is blocked by stopper; When cleaner quits work, it is possible to stopper is taken off, thus the water in holding tank 11 is discharged. Further, preferably, one end away from holding tank 11 first opening of cylinder 22 is connected by pipeline and the first water pump, for making the water in the first water pump suction holding tank 11, and make the water in this holding tank 11 discharge from the first shower nozzle 20, pollute as such, it is possible to reduce water produced by spray for dust suppression method.
Further, drainage screen 11 can be the wire netting of 150 order-300 orders, it is possible to include one or more layers wire netting.
Further, displacement transducer 21 is also called linear transducer, is a kind of linear unit belonging to metal sensing, and the effect of displacement transducer is that various measurands are converted to electricity. In process of production, the measurement of displacement is generally divided into measurement full size and mechanical displacement two kinds. Different by the form of measured variable conversion, displacement transducer can be divided into analog and digital two kinds. Analog can be divided into again physical property type and structural type two kinds. Conventional displacement transducer is in the majority with analog structure type, including potentiometric displacement transducer, inductive displacement transducer, selsyn, capacitive displacement transducer, electric vortex type displacement sensor, Hall displacement transducer etc. Displacement transducer 21 is mainly used in expansion link 18 preset displacement downstream is converted to alarm signal, and this alarm signal is sent to controller, and controller drives the first water pump further according to alarm signal. It should be noted that in the present embodiment, alarm signal is current signal, controller is mainly current amplifier, its effect is alarm signal to be amplified through processing, and then the signal after amplification controls the solenoid of the first water pump, thus starting the first water pump to carry out pump water. Controller can also is that simple amplifier, it would however also be possible to employ the controller that CPU is constituted. Due in the present invention, this controller does not seek protection, and does not just specifically repeat.
In the present embodiment, displacement transducer 21 is arranged on the inwall of pipeline 1, and cleaner also includes the seal closure 23 being arranged on the inwall of pipeline 1 and being sealed by displacement transducer 21 together with projection 16 and pipeline 1 inwall. Make displacement transducer 21 will not be carried the airflow influence of dust by seal closure 23.
Further, in the present embodiment, division board 13 includes leading portion 131, stage casing 132 and back segment 133; Leading portion 131, stage casing 132 and back segment 133 are respectively in tabular; Stage casing 132 is horizontally disposed with, and the rear end of leading portion 131 is connected with stage casing 132, and the front end of leading portion 131 is downward-sloping; The front end of back segment 133 is connected with stage casing 132, and the rear end of back segment 133 is downward-sloping; Piston 17 has the inclined-plane 171 parallel with leading portion 131, as shown in Figure 2. When spring 19 is in relaxed state, inclined-plane 171 and the leading portion 131 of piston 17 fit, and so, piston 17 is just completely plugged by second channel; Along with piston 17 downstream slides, it is separated out gap between inclined-plane 171 and the leading portion 131 of piston 17, and this gap is increasing.
In the present embodiment, further, cleaner also include being arranged on first passage be positioned at drainage screen 14 downstream position, for open or close the closing door 24 of first passage and be connected with closing door 24, driving mechanism 25 for driving closing door 24 to slide. When spring 19 is in relaxed state, closing door 24 is in open mode. Controller is also connected with driving mechanism 25, after being used for the alarm signal sent when receiving displacement transducer 21 because of expansion link 18 downstream generation preset displacement, drives closing door 24 to close first passage by controlling driving mechanism 25. When completing the task of closing first passage when closing door 24, the space being positioned at piston 17 downstream of second channel can produce negative pressure quickly. It is thus possible to efficiently open second channel. In the present embodiment, the position being positioned at closing door 24 place of pipeline 1 offers the second opening, and closing door 24 is scalable in this second opening; Driving mechanism 25 includes two pulleys being separately positioned on closing door 24 both sides, and the wheel face of these two pulleys offsets with two sidepieces of closing door 24 respectively; Driving mechanism 25 also include with controller be electrically connected, for starting to drive the second motor of pulley rotation under the control of the controller. The slip of pulley can make closing door 24 in the effect lower slider of frictional force. So, closing door 24 is under the effect of frictional force, it is possible to stretch out in pipeline 1 from the second opening part, thus being opened by first passage. Being appreciated that closing door can also is that rotation door, driving mechanism can be the mechanism driving closing door to rotate, and these are all prior art, just specifically do not repeat.
Further, locating part 12 is the plate body being vertically arranged, and is close to leading portion 131 or the stage casing 132 of division board 13. So, the area of section of second channel is increasing in locating part 12 downstream. So, when air-flow is after locating part 12, the speed of air-flow can reduce, and so, the water that the dust in air-flow is easier to be sprayed by the first shower nozzle 20 filters.
Further, the back segment 133 of division board 13 offers multiple second through hole 134, and, the back segment 133 of division board 13 is positioned at the top of holding tank 11. Meanwhile, cleaner also include the second water pipe (not shown) extending in first passage, the second shower nozzle 26 being in first passage and being positioned on the end above back segment 133 being arranged on the second water pipe and be arranged on the second water pipe, for drive water along second water pipe flowing and from second shower nozzle 26 ejection the second water pump (not shown). Controller is also electrically connected with the second water pump, after being used for the alarm signal sent when receiving displacement transducer 21 because of expansion link 18 downstream generation preset displacement, starts the second water pump to drive water to spray from the second shower nozzle 26. So, when the second shower nozzle 26 starts to spray water, water can drop on the back segment 133 of division board 13, and falls from the second through hole 134. When part carries the air-flow of dust by the second through hole 134, it is possible to contact more fully with water, thus filtered. Preferably, one end away from holding tank 11 first opening of cylinder 22 connects also by pipeline and the second water pump, for making the water in the second water pump suction holding tank 11, and makes the water in this holding tank 11 discharge from the second shower nozzle 26.
It should be appreciated that for those of ordinary skills, it is possible to improved according to the above description or converted, and all these are improved and convert the protection domain that all should belong to claims of the present invention.
