Description
Technical field
The utility model belongs to deduster field, is specifically related to the scavenge unit of bulk goods blanking in a kind of railway tunnel.
Background technology
At present, removing bulk goods blanking in railway tunnel is both at home and abroad that puzzlement railway tunnel normally uses and affects the significant problem of train safe running on time.In the railway tunnel of reality, because railroad train stirs by producing high energy air during tunnel, occur bulk goods (as coal) blanking phenomenon, blanking is saved bit by bit for a long time and is directly polluted railway roadbed, causes plate knot of ballast bed, and then has a strong impact on line security operation generation.At present, conventional artificial removing operating type, the activity duration is long, and labour intensity is large.Industrial dust collector common on market cannot be used in railway tunnel dedusting rationally, efficiently.In how quick, timely removing railway tunnel, bulk goods blanking becomes a difficult problem.
Summary of the invention
The utility model object is to provide the scavenge unit of bulk goods blanking in a kind of railway tunnel, effectively can overcome the shortcoming that prior art exists.
The utility model is achieved in that as shown in Figure 1, 2, and its architectural feature is provided with along railroad track direction in railway tunnel 10 to save dust removing tube 1 ', 1 by n " ... 1
n' the cleaning shaft that connects into, n is positive integer, connected by connecting ring 2 between each joint dust removing tube, the front end of cleaning shaft is connected with industrial dust collect plant 8 by dust flue 7, the end of cleaning shaft is connected with negative pressure and flow, current velocity controller 4, the periphery often saving dust removing tube is shaped with the interface tube 3 be connected with hose 5, the end of hose 5 is provided with suction nozzle 6, as shown in Figure 4, the upper end of interface tube 3 that dust removing tube periphery is shaped with is provided with and controls by compression spring 301 access flap 302 that compresses, negative pressure and flow, the structure of current velocity controller is as shown in Figure 7, left and right end is shaped with the left and right adjustment ring 402 of flange, 403 are connected by screw thread, the flange of left adjustment ring 402 is connected with the left end cap 401 being shaped with conical central hole by bolt group 408, the flange of right adjustment ring 403 is connected with the right end cap 404 being shaped with centre bore by bolt group 409, bottom is that the bowl seal part 406 of taper is placed in left and right adjustment ring 402, in 403 chambeies formed, the conical surface of bowl seal part bowl base cone face and left end cap 401 centre bore is affixed, the left and right end of compression spring 405 respectively with bowl seal part inner bottom part and right end cap 404 inner face inconsistent, n-th joint dust removing tube terminal surface is connected by bolt group 409 with right end cap 404.
The utility model advantage and good effect have employed dust catcher dust-cleaning principle, and installed negative pressure and air mass flow, flow velocity adjusting device additional, by controlling work vacuum magnitude to ensure that in cleaning shaft, air flow rate, flow velocity meet job requirement, improve efficiency of dust collection.Industrial dust collect plant is arranged on outside railway tunnel, is beneficial to the filtration to dust, collection, transport and unified process.

detailed description of the invention:
As shown in Figure 1, when needs are to when carrying out dedusting in railway tunnel, first hose 5 is connected with the interface tube 3 on dust removing tube, again dedusting pipeline front end is connected with industrial dust collect plant 8 by dust flue 7, dedusting line end be connected with negative pressure and flow, current velocity controller 4, the suction nozzle 6 namely by hose 5 carries out dedusting again.The effect of negative pressure and flow, current velocity controller 4 be when air flow rate in dedusting pipeline, flow velocity reduce negative pressure raise time, compressed at atmospheric pressure effect downforce spring 405 in the negative pressure of cleaning shaft end and flow, current velocity controller 4, left end cap 401 is opened with the conical contact face of Bowl seal part 406, in pipeline, gas flow, flow velocity rise, improve ash transfer efficiency in pipeline, in cleaning shaft, negative pressure is by left adjustment ring 402 and right adjustment ring 403 adjustable diameter and screw adjusting.
