Sack cleaner step-by-step movement blowback mechanism
The utility model relates to a kind of deduster blowback mechanism, in particular for chamber-dividing counter-blowing wind sleeve formula deduster step-by-step movement blowback mechanism.
Blowback wind sleeve formula deduster commonly used at present all sets out air valve and blowback valve at each locellus.When this locellus need stop to filter when carrying out deashing, promptly close out air valve automatically, open the blowback valve.If the locellus of sack cleaner is more, the valve of use is just more, thereby the chance that breaks down also increases, and maintenance load strengthens thereupon.
The purpose of this utility model provides a kind of sack cleaner step-by-step movement blowback mechanism, and it need all not set out air valve and blowback valve in each locellus of deduster, so it is simple in structure, and is stable.
The purpose of this utility model is achieved in that a kind of sack cleaner step-by-step movement blowback mechanism, comprise the air-out person in charge and transfer valve, the inside of being responsible in the deduster air-out is provided with flexible reverse-blow pipe, slide rail and transmission mechanism, transmission mechanism is along the slide rail move left and right, blowback air port on the flexible reverse-blow pipe that links to each other with transmission mechanism can be docked with each locellus air outlet, and blowback wind telescoping tube one end is connected with a blowback wind transfer valve.
Transmission mechanism links to each other with the signal of telecommunication that can control the keying of blowback wind transfer valve.
The signal of telecommunication is a travel switch, and the collision block of travel switch is located at flexible reverse-blow pipe posterior angle, and the contact of travel switch is located in the air-out person in charge that can contact with collision block.
One side at flexible reverse-blow pipe is provided with a blowback air port, and air-out is responsible for and is provided with the locellus air outlet that can dock with it.
Transmission mechanism is a link chain mechanism, and roller chain is installed in air-out and is responsible on the sprocket wheel of two end inboards, and the reducing motor that passes air-out person in charge's outer panel and top by a sprocket shaft is connected.
Be provided with location upper hopper chute, glidepath in the inside that the deduster air-out is responsible for, link chain mechanism is slidingly connected in the glidepath, and locatees by upper hopper chute.
Slide rail is a double sided slider bar, Yi Bian be that a side in blowback air port is being arranged, at the upper and lower side of each locellus air outlet flange a slide rail is set respectively; Another side is that a side relative with the blowback air port respectively is provided with a slide rail up and down.
Relying on every section two ends between flexible each section of reverse-blow pipe is provided with rigid fixing seal ring and keeps sealing.
The base plate that air-out is responsible for is provided with the chain bracket that prevents that chain from sinking.
Blowback air port one side that air-out is responsible for is provided with the blowback air port chute that guarantees sealing.
Therefore the utility model, need all not set out air valve and blowback valve because the back-flushing valve door can move by transmission mechanism in each locellus of deduster between each locellus, reduced the quantity of valve, thereby reduces the maintenance workload of valve; It is simple in structure, stable.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the vertical view of Fig. 1.
As shown in Figure 1, 2, 3, the utility model sack cleaner step-by-step movement blowback mechanism mainly comprises electric butterfly valve 1, slide rail, transmission mechanism and flexible reverse-blow pipe 5.Be provided with flexible reverse-blow pipe 5, slide rail 7 and transmission mechanism in the deduster air-out person in charge 3 inside, transmission mechanism is along the slide rail move left and right, blowback air port on the flexible reverse-blow pipe 5 that links to each other with transmission mechanism can be docked with each locellus air outlet, blowback wind telescoping tube one end is connected with a blowback wind transfer valve, and transmission mechanism links to each other with the signal of telecommunication that can control the keying of blowback wind transfer valve.
Embodiment
One side at flexible reverse-blow pipe 5 is provided with a blowback air port 10, and air-out is responsible for 3 and is provided with the locellus air outlet 12 that can dock with it, and the size in blowback air port 10 equates with the size of deduster locellus air outlet 12 or be smaller.End at flexible reverse-blow pipe 5 is provided with blowback wind transfer valve 1, promptly electronic dish valve, blowback wind inlet along the A of Fig. 1 to entering locellus, locellus pure qi (oxygen) inlet along the B among Fig. 3 to, air outlet along the C of Fig. 2 to; The reverse-blow pipe 5 that stretches is driven by link chain mechanism 4 and reducing motor 6, realizes the intermittently move left and right of location, and roller chain is installed in air-out and is responsible on the sprocket wheel of two end inboards, and the reducing motor that passes air-out person in charge's outer panel and top by a sprocket shaft is connected; Reducing motor 6 should have braking function; Be provided with location upper hopper chute 2, glidepath 7 in the deduster air-out person in charge 3 inside, link chain mechanism 4 moves on glidepath 7, and locatees by upper hopper chute; Link chain mechanism 4 also links to each other with travel switch 9 simultaneously, utilize the keying of signal of telecommunication control blowback wind transfer valve 1, dock with locellus air outlet 12 in realization blowback air port 10, that is to say, when blowback air port 10 moves to a certain locellus and aims at when needing the locellus air outlet 12 of deashing, the collision block travel switch contact interior with being located at the air-out person in charge that is located at pipeline section posterior angle, blowback air port contacts, and sends instruction.Controller is simultaneously controlled motor and is suspended (dwell time is the blowback wind time, can set), and the blowback wind transfer valve that one side is opened YE control carries out anti-blow cleaning dust; Valve closing when reverse gas cleaning finishes; After (can setting) after a while, flexible reverse-blow pipe 5 moves to next locellus with link chain mechanism again, reverse-blow pipe intersegmental have a rest move finish the deashing of all locellus of deduster after, again by the oppositely running continuously of travel switch 9 instruction link chain mechanisms, make flexible blowback tuyere tube 5 get back to starting point, wait for next cleaning cycle.
Chain bracket 8 is positioned on the air-out person in charge 3 the base plate, and its effect is to prevent that chain from sinking.
Blowback air port chute 11 is positioned on the air-out person in charge 3 blowback air port one side, and its effect is the sealing when keeping air outlet to dock with the blowback air port.
Have again, also blowback wind Telescopic pipe support can be located in the slide rail of both sides:, a slide rail respectively is set at the upper and lower side of each locellus air outlet flange Yi Bian be that a side in blowback air port is being arranged; Another side is that a side relative with the blowback air port respectively is provided with a slide rail up and down, and telescoping tube moves along slide rail, thus the sealing can keep air outlet to dock the time with the blowback air port.
Rely on every section two ends between each section of telescoping tube and rigid fixing seal ring is set keeps sealing, each segment length is determined according to the stability of supporting.
