[0002] At present, the common technology for controlling the unorganized dust emission in industrial material sheds is to arrange a single-fluid spray dust removal device at the top of the space where dust removal is required. In order to achieve full coverage of the dust removal in the space, a large number of nozzles need to be arranged on the top of the entire dust removal space, and water mist is sprayed downward from the top. The water mist adsorbs floating dust particles during the falling process, so as to achieve full-space dust removal. The biggest difficulty of this technology lies in the later maintenance, because the spray dust removal nozzles need to be cleaned and replaced regularly. Since all the nozzles are fixedly installed at the top, special lifting equipment or aerial catwalks need to be borrowed to maintain the spray equipment at high altitude. This method results in high maintenance costs, and the maintenance personnel need to work at high altitude, which is very dangerous and increases potential safety hazards.

[0027] An automatic high - altitude lifting spray dust - removal device, as Figure 1 、 Figure 2 shown, includes a fixed seat 1 and a spray terminal 4. The fixed seat 1 is installed on the dust - removal material shed, and the spray terminal 4 is connected to the fixed seat 1 through a wire rope 10 and can be lifted up and down under the action of the wire rope 10. A number of downward - jetting dry fog nozzles 4 - 1 are installed on the spray terminal 4, and a water cavity communicating with the outlet high - pressure rubber hose 20 is also provided inside the spray terminal 4.

[0028] As Figure 1 shown, the fixing base 1 is a rectangular mounting base with an opening at the bottom, enclosed by a top plate 1-1, a bottom plate 1-2 and two side plates. Two vertical plates 1-3 extending downward are connected to the top plate 1-1. Inner bearing seats are provided on both of the two vertical plates 1-3. Both ends of the reel 5 are respectively installed on the inner bearing seats of the two vertical plates 1-3. One end of the reel 5 is drivingly connected to a lifting drive motor 7, and the other end is connected to a lifting limit switch assembly 9. The reel 5 rotates driven by the lifting drive motor 7. Two wire rope reel wheels 6 are symmetrically arranged on both sides of the reel 5. The wire rope reel wheels 6 are key-connected to the reel 5 and rotate synchronously with the reel 5. One end of a wire rope 10 is fixed on the wire rope reel wheel 6, and the other end passes through the bottom plate 1-2 of the fixing base 1 and is fixedly connected to the spray terminal 4.

[0029] The lifting limit switch assembly 9 includes a driving wheel 9-1, a middle limit wheel 9-2, a middle limit switch 9-3, a lower limit wheel 9-4 and a lower limit switch 9-5. As Figure 3 shown, the driving wheel 9-1 is coaxially arranged with the reel 5 and rotates synchronously. The middle limit wheel 9-2 and the lower limit wheel 9-4 are respectively arranged on both sides of the driving wheel 9-1. The wheel shafts are fixed on the vertical plate 1-3, and the middle limit wheel 9-2 and the lower limit wheel 9-4 are both separately meshingly connected with the driving wheel 9-1 without affecting each other. The lower limit switch 9-5 is arranged outside the lower limit wheel 9-4, and the middle limit switch 9-3 is arranged outside the middle limit wheel 9-2. A lower push rod 9-7 for triggering the lower limit switch 9-5 is arranged on the lower limit wheel 9-4, and a middle push rod 9-6 for triggering the middle limit switch 9-3 is arranged on the middle limit wheel 9-2. The triggering frequencies of the middle limit switch 9-3 and the lower limit switch 9-5 are adjusted by the tooth ratio between the middle limit wheel 9-2, the lower limit wheel 9-4 and the driving wheel 9-1 to avoid frequent triggering.

[0030] Furthermore, a wire guiding wheel 8 for guiding is also arranged on the bottom plate 1-2 of the fixing base 1. The wire rope 10 first passes downward through the wire guiding wheel 8 and then passes out through the wire guiding hole of the bottom plate 1-2 of the fixing base 1, so as to effectively guide the wire rope 10 and ensure that the spray terminal 4 can be lifted flexibly and smoothly.

[0031] Furthermore, suspension rings 4-2 are fixedly arranged on both sides of the top of the spray terminal 4. A hook 10-1 is arranged at the end of the wire rope 10. The wire rope 10 is hooked on the suspension rings 4-2 to achieve connection. Preferably, the hook 10-1 is a self-locking hook 10-1.

[0032] Furthermore, a plurality of mounting holes are arranged on the top plate 1-1, and the fixing base 1 is fixedly connected to the dust removal shed through the mounting holes.

[0033] Further, the spray terminal 4 is a frame formed by staggered arrangement of multiple steel pipes, and the dry fog nozzles 4-1 are fixedly installed in an array at the bottom of the frame.

[0034] A plurality of threaded holes are provided outside the opening of the bottom plate 1-2, and the waterway female head mounting seat 2 is installed on the fixed seat 1 by bolts. The waterway female head mounting seat 2 is of a cylindrical structure, and a fixed-end pipeline assembly is installed inside the waterway female head mounting seat 2. The fixed-end pipeline assembly includes a fixed-end mounting plate 13-1 horizontally fixed on the waterway female head mounting seat 2 and a fixed-end water supply pipe 13-2 whose lower end penetrates through the fixed-end mounting plate 13-1. The upper end of the fixed-end water supply pipe 13-2 is hermetically connected to the inlet high-pressure rubber hose 16, and its lower end is connected to the hydraulic quick coupling female head 14. Four electromagnets are circumferentially and evenly arranged on the fixed-end mounting plate 13-1 with the fixed-end water supply pipe 13-2 as the center.

[0035] The electromagnet assembly is a push-pull electromagnet, including a push electromagnet 11 and a pull electromagnet 12, which are used in pairs. That is, the four electromagnets include two push electromagnets 11 and two pull electromagnets 12, and the push electromagnet 11 and the pull electromagnet 12 are staggered. The tops of the push electromagnet 11 and the pull electromagnet 12 are both fixed on the fixed-end mounting plate 13-1. The bottom of the pull electromagnet 12 is fixed on the pull plate 15 and can freely expand and contract along the axial direction. The other end of the push electromagnet 11 passes through the light hole on the pull plate 15 and then hangs out. A through hole is opened in the center of the pull plate 15. The diameter of the through hole is larger than the outer diameter of the hydraulic quick coupling male head 17, and the center hole of the pull plate 15 is concentric with the hydraulic quick coupling female head 14, ensuring that when the electromagnet is energized and contracts, driving the pull plate 15 to move upward, the pull plate 15 further drives the locking ring of the hydraulic quick coupling female head 14 to move upward, so as to facilitate the separation and connection of the waterway. An upper limit switch 21 is also provided at the bottom of the fixed-end mounting plate 13-1. Further, external threads are provided at both ends of the fixed-end water supply pipe 13-2, and the fixed-end water supply pipe 13-2 is threadedly connected to both the hydraulic quick coupling female head 14 and the inlet high-pressure rubber hose 16.

[0036] Further, a plurality of light holes are evenly arranged on the outer edge of the fixed-end mounting plate 13-1 for fixing the fixed-end mounting plate 13-1 on the waterway female head mounting seat 2.

[0037] Further, the fixed-end mounting plate 13-1 is provided with four light holes for installing fixed electromagnets.

[0038] At the top of the spray terminal 4, a waterway male connector mounting seat 3 is installed. The waterway male connector mounting seat 3 is a cylindrical structure with a circular ring plate at the bottom and an open upper end. The waterway male connector mounting seat 3 is concentrically arranged with the waterway female connector mounting seat 2, and the outer diameter of the waterway male connector mounting seat 3 is smaller than the inner diameter of the waterway female connector mounting seat 2, ensuring that the waterway male connector mounting seat 3 can move freely up and down within the waterway female connector mounting seat 2 without mutual collision and friction. A mobile pipeline assembly is installed inside the waterway male connector mounting seat 3. The mobile pipeline assembly includes a mobile mounting plate 18-1 horizontally fixed on the waterway male connector mounting seat 3 and a mobile water supply pipe 18-2 fixedly connected to the mobile mounting plate 18-1. The top end of the mobile water supply pipe 18-2 penetrates upward through the mobile mounting plate 18-1 and is fixedly connected to a hydraulic quick connector male head 17, and the lower end of the mobile water supply pipe 18-2 is connected to a high-pressure water outlet hose 20.

[0039] The mobile mounting plate 18-1 and the circular ring plate are connected by four screw columns arranged evenly, and a spring 19 is sleeved on the screw columns. It should be noted that when installing the spring 19, there should be a certain amount of compression to ensure that when the electromagnet pushes the hydraulic quick connector male head 17, sufficient resilience is provided to completely eject the hydraulic quick connector male head 17 from the hydraulic quick connector female head 14, realizing the disconnection and separation of the waterway.

[0040] An upper shift lever 22 is also connected to the waterway male connector mounting seat 3. The upper shift lever 22 is correspondingly arranged below the upper limit switch 21. When the waterway male connector mounting seat 3 moves up to the top limit position, the upper shift lever 22 triggers the upper limit switch 21 installed at the bottom of the fixed-end mounting plate 13-1 to achieve limit control.

[0041] Further, the waterway male connector mounting seat 3 is fixedly connected to the spray terminal 4 by bolts.

[0042] Further, external threads are provided at both ends of the mobile water supply pipe 18-2. The mobile water supply pipe 18-2 is threadedly connected to the hydraulic quick connector male head and the high-pressure water outlet hose 20 respectively.

[0043] It should be noted that both the waterway male connector mounting seat 3 and the waterway female connector mounting seat 2 are cylindrical and concentrically arranged. The hydraulic quick connector is a self-sealing hydraulic quick connector. When the male head and the female head are buckled, they are connected and the medium can pass through; when the male head and the female head are separated, their pipe orifices are closed respectively, the pipeline is disconnected, but the medium does not leak.

[0044] The working process of the present utility model is as follows:

[0045] Ascending stage: When the spray dust removal device receives the ascending signal, the lifting drive motor rotates. The wire rope reel is driven by the reel to rotate, causing the wire rope to gradually wind up. The wire rope pulls the spray terminal to rise gradually. At the same time, the middle lever triggers the middle limit switch, and the middle limit switch sends a signal. The pull-type electromagnet is energized to perform a contraction action, pulling the locking ring of the female head of the hydraulic quick connector upward. The lifting drive motor continues to rotate, and the spray dust removal device continues to rise. When the upper lever 22 on the waterway male head mounting seat touches the upper limit switch on the waterway female head mounting seat, the lifting drive motor stops operating. At this time, the male head of the hydraulic quick connector is inserted into the female head of the hydraulic quick connector. The pull-type electromagnet is powered off and returns to the extended state, driving the locking ring to move downward to lock the male and female heads of the hydraulic quick connector, and the waterway connection is completed.

[0046] Descending stage: When the spray dust removal device receives the descending signal, the lifting drive motor rotates in the reverse direction. The lower lever triggers the lower limit switch, and the pull-type electromagnet is energized to perform a contraction action, pulling the locking ring of the female head of the hydraulic quick connector upward. Immediately afterwards, the push-type electromagnet is energized, and the extending rod pops out to push the male head of the hydraulic quick connector downward to separate the female and male heads of the hydraulic quick connector, and the waterway is separated. The wire rope pulls the spray terminal to descend gradually. After the lever on the waterway male head mounting seat separates from the upper limit switch at the top of the waterway female head mounting seat, the electromagnet is powered off and returns to the initial state. The wire rope pulls the spray terminal to continue descending until the lower limit switch is triggered, the lifting drive motor is powered off and stops working, and the spray terminal descends to the set position. The ground staff can then clean and maintain the dry mist nozzles of the spray dust removal device.

[0047] The above are only the preferred embodiments of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the present invention.
