Detailed Description

Referring to fig. 1-2, the utility model discloses a mining rotation type dust suppression shower nozzle, motor 1 including fixed setting, the both ends that hollow shaft and pivot 3 were adopted in pivot 3 of motor 1 are overhanging respectively in motor 1's both sides, the one end of pivot 3 has inlet channel 5 through rotary joint 4 sealing connection, the other end sealing installation of pivot 3 has shower nozzle 6, be provided with nozzle 7 on the shower nozzle 6. During the use, through conventional mechanisms such as water pumps with water pump suction to inlet channel 5, under the effect of pressure, water gets into 6 insides of shower nozzle behind inlet channel 5, rotary joint 4, pivot 3 in proper order, spouts from nozzle 7 at last. The rotating shaft 3 of the motor 1 rotates to drive the spray head 6 and the spray nozzle 7 to rotate, so as to form a rotating water curtain. The rotary joint 4 may be a structure capable of realizing a rotary seal, which is generally known in the art.

Further, the motor 1 is a pneumatic motor, and the motor 1 is communicated with an air inlet pipeline 2. The motor 1 only needs to overcome self-bearing resistance, frictional resistance of the rotary joint 4 and resistance formed by the water curtain and air during rotation, so that the configured motor 1 has extremely small specification and only needs to adopt a single-blade type or a turbine type. The pneumatic motor can better meet the use requirement and is a preferable structure, and in other embodiments, a hydraulic motor and an electric motor can be used.

Further, an air inlet quantity regulating valve 8 is installed on the air inlet pipeline 2. The rotating speed of the rotating shaft 3 can be controlled by adjusting the opening size of the air inlet regulating valve 8, so that the rotating speed of the nozzle 7 is realized. The faster the nozzles 7 are rotated, the fewer the number of nozzles 7 are required to form the water curtain.

Further, the nozzle 6 is a cylindrical housing sleeved at the end of the rotating shaft 3, the cylindrical housing is coaxial with the rotating shaft 3 of the motor 1, the outer end surface of the cylindrical housing is closed, and the inner end surface of the cylindrical housing is provided with a through hole for embedding the rotating shaft 3 in a sealing manner. In detail, the through hole of the inner end face of the spray head 6 is a threaded hole, the end part of the rotating shaft 3 corresponding to the spray head 6 is provided with an external thread, and the spray head 6 and the rotating shaft 3 are screwed and fixed through the threads. Furthermore, a plurality of nozzles 7 are uniformly distributed on the side wall of the cylindrical shell along the circumferential direction, and/or a plurality of nozzles 7 are uniformly distributed on the outer end surface of the cylindrical shell.

Further, the water inlet pipe structure further comprises a base plate 9 fixedly arranged, the motor 1 is fixed on the base plate 9, and a support frame 10 used for supporting the water inlet pipe 5 is further fixed on the base plate 9. The arrangement of the base plate 9 facilitates the installation of the motor 1, and the arrangement of the support frame 10 improves the structural stability.

The utility model discloses in, the mounted position of nozzle 7 and quantity carry out specific settlement as required can, three kinds are given below the utility model discloses a mining rotation type dust suppression shower nozzle 6's concrete installation situation:

fig. 3 shows a situation in which the installation is horizontal (the shaft of the motor 1 is horizontal) in a roadway. When the wind pressure and the wind quantity of the on-site gas supply are large, the spray head 6 rotates fast, and two nozzles 7 can be symmetrically arranged; when the wind pressure and the wind quantity are small, the spray head 6 rotates slowly, and four nozzles 7 can be installed. The water spraying direction of the spray nozzles 7 is shown in the figure, namely, the spray nozzles rotate on the section of the roadway. The installation mode forms a layer of water curtain on the section of the roadway. Meanwhile, when the nozzle 7 rotates to the top plate, water sprayed out of the nozzle 7 easily forms water drops after the water hits the top plate, and therefore water mist is easily formed.

Fig. 4 shows a situation in which the installation is vertical (the shaft of the motor 1 is vertical) in a roadway. The number of the nozzles 7 is four, and the nozzles 7 are arranged in a straight line shape, and the installation and water spraying directions of the nozzles 7 are shown in fig. 3. The mounting mode can form a front layer water curtain and a rear layer water curtain on the section of the roadway, namely, an annular water curtain is formed on the horizontal plane of the roadway.

Fig. 5 shows the situation of a conveyor transfer point in a roadway mounted vertically (with the shaft of the motor 1 vertical). Basically the same as fig. 4, but with a low mounting height, above the transfer point of the conveyor, an auxiliary support can be mounted on the ceiling or on the frame of the conveyor. The number of the nozzles 7 is 3, and the installation of the nozzles 7 and the water spraying direction are shown in fig. 5. The rotary water curtain can surround the dust at the transfer point of the conveyor, and the dust suppression effect is good.

While the invention has been particularly shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
