Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims. Furthermore, in the present description, the drawings are not to scale and like reference numerals refer to like parts.
First embodiment
The tower crane spraying dust suppression system of this embodiment includes water tank 1, water pump 4, riser 2, horizontal pipe 3. Wherein the water tank 1 stores therein water for spraying. The water pump 4 may be a submersible pump, which is placed in the water tank 1 for supplying water into the riser 2. Of course, it may not be a submersible pump and need not be located in the tank 1. The vertical pipe 2 is communicated with the horizontal pipe 3, and the vertical pipe 2 and the horizontal pipe 3 are connected together to be called a water pipe. The water inlet pipe of the water pump 4 is communicated with the water tank 1, and the water outlet pipe of the water pump 4 is communicated with the vertical pipe 2 and used for supplying water to the water pipe.
Riser 2 upwards extends to the rotation mechanism of tower crane along the body of the tower crane, and horizontal pipe 3 extends along the slewing arm of tower crane and arranges. The vertical pipes 2 can be fixed on the tower body by pipe clamps at certain intervals, and the horizontal pipes 3 are fixed on the rotary arm by the pipe clamps at certain intervals. A plurality of water spray holes 31 are provided at regular intervals in the pipe body of the horizontal pipe 3. Preferably, the water spout holes are downward. Water is supplied to the water pipe through the water pump 4, and the water mist is sprayed downwards through the plurality of water spraying holes 31, so that the dust falling effect is achieved. Preferably, the watering holes 31 are in the form of a plum blossom.
In an alternative embodiment, the inner diameter of the horizontal pipe 3 is smaller than the inner diameter of the riser 2. For example, the vertical pipe adopts D40mm, and the horizontal pipe adopts D32mm, which has the effect of reducing the pressure, can reduce the load of the water pump 4 and meet the flow of each water jet hole 31.
In an alternative embodiment, the water pipe is made of polyethylene, has certain flexibility, and the vertical pipe 2 is communicated with the horizontal pipe 3 by a hot melting 90-degree elbow. And, still be provided with gyration stop gear, when the gyration arm rotated 360, the motor that drives the gyration arm pivoted stopped and can only reverse the gyration, and this makes horizontal pipe 3 can not rotate more than the round for riser 2, so can not cause the damage to polyethylene tubular product.
In an alternative embodiment, a float switch 5 is arranged in the water tank 1, and the float switch 5 is provided with an upper water level limit and a lower water level limit, so that water overflow and overheating of the water pump can be prevented.
In an alternative embodiment, a check valve 6 and a water pressure gauge 7 are also arranged between the water pump 4 and the water pipe.
In an alternative embodiment, a remote control and dust concentration detector 8 are provided to facilitate control of the amount of water sprayed. The dust concentration detector 8 is arranged at a position below the rotation area of the tower crane. Dust concentration detector 8 is used for observing dust concentration situation, and the tower crane spraying system uses the water smoke dust fall measure of different grades according to the dust concentration situation that dust concentration detector 8 was observed.
The first-stage dust settling measure adopts fine water mist for dust settling, and the content of medium and small particle dust in the air is reduced;
and the second-stage dust falling measure adopts a dustproof covering agent, the dustproof covering agent is sprayed on the surface of dust, the dustproof covering agent forms a layer of protective film on the surface of the dust, and the raised dust is reduced by means of the protective film.
Wherein the dust concentration is 0-10 mg/m3When the dust is not reduced, the dust reduction measure is not started;
the dust concentration is more than 10mg/m3～100mg/m3Starting a first-stage dust settling measure;
the dust concentration is more than 100mg/m3And in time, a secondary dust settling measure is used.
Second embodiment
The second embodiment includes the contents of the first embodiment, and only the technical features different from the first embodiment will be described below.
The inner diameter of the horizontal pipe 3 is gradually reduced in a direction away from the center of rotation, as shown in fig. 3, and the water spray holes 31 are gradually changed from downward to upward. Also, the watering holes 31 do not need to be strictly gradual to spray upwards. The purpose that sets up like this is because the slewing arm length of tower crane is limited for the dust fall scope of the water smoke that sprays is limited, for increaseing its scope of spraying water smoke, makes to dwindle gradually to the pipe diameter of the direction of keeping away from the centre of rotation, just also makes water spray pressure crescent, makes the water smoke that the hole for water spraying 31 erupted far away, can enlarge the spray regime of water smoke relatively. However, in order to reduce the risk of spraying high-pressure water, the water spray holes 31 are directed upward so that the sprayed mist is sprayed upward and then falls downward without any risk. Furthermore, as shown in fig. 2, a plurality of water spray holes 31 may be provided at the tip of one end of the horizontal pipe 3 in the direction away from the rotation center, and the water spray holes 31 may spray horizontally, so that the spray distance of the mist may be continuously extended.
Third embodiment
The third embodiment includes the contents of the first embodiment, and only the technical features different from the first embodiment will be described below.
The level vial 3 comprises successively communicating level vial segments of progressively decreasing internal diameter, as shown in FIG. 2. For example, the horizontal tube 3 comprises horizontal tube segments of D32mm, D30mm, D28mm, D25mm connected in series. And, the water jet holes 31 of each horizontal pipe segment are gradually changed from downward to upward (for the convenience of illustration, the conversion process of part of the water jet holes 31 is omitted in the figure). As shown in fig. 3. A plurality of water spraying holes 31 can be further formed in the end of one end, far away from the rotation center, of the horizontal pipe 3, the water spraying holes 31 spray horizontally, and the spraying distance of water mist can be further prolonged.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
