Description

Technical Field

[0001] The utility model relates to the field of spray dust suppression, in particular to a two-fluid spray dust suppression device. Background Art

[0002] When crushing materials, a lot of dust will appear, and there are generally various dust removal and suppression devices. The most commonly used is the two-fluid water mist dust removal and suppression device. Water mist dust suppression is an advanced technology superior to traditional spray dust removal technology and has been widely used in places such as mines, power plants, ports, and garbage treatment stations. The dry fog dust suppression technology captures dust through "cloudy" water mist, combines the water mist with dust particles in the air to form aggregates of dust and water mist, and settles under the action of gravity to achieve source dust suppression.

[0003] According to the disclosed patent CN219376545U, a two-fluid spray dust suppression device in the crushing section belongs to the technical field of two-fluid spray dust suppression devices, including a frame formed by four support plates. A connecting shaft is vertically penetrated through the vertical sides of the frame. One end of the connecting shaft is connected to an adjusting component, and the other end of the connecting shaft is connected to a water guide pipe. A two-fluid nozzle body is arranged on the water guide pipe. A rotating component is arranged on the horizontal side of the frame, and a protective housing is arranged on the rotating component. The rotating component includes a first motor and a rotating rod arranged at the output end of the first motor. The first motor is arranged on the top of the frame. The bottom of the rotating rod penetrates through the frame, and three groups of opposite threads are provided on the rotating rod. A threaded sleeve is sleeved on each group of opposite threads, and one side of the threaded sleeve is connected to the protective housing. In the process of implementing the present utility model, the inventor found that at least the following problems in the prior art have not been solved. The existing water guide pipe is adjusted synchronously, so that only the dust suppression direction can be adjusted. Furthermore, for large-scale dust suppression, the angle of the water guide pipe needs to be adjusted continuously, which is rather inconvenient. Moreover, the water and gas are directly connected to the conduit through the connecting pipe, so that impurities in the water easily block the two-fluid nozzle, thus affecting the dust suppression effect. Therefore, it is necessary to design a new technical solution to solve this problem. Summary of the Utility Model

[0004] The purpose of the present utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a two-fluid spray dust suppression device to solve the technical problems that the current water guide pipe is adjusted synchronously, so that only the dust suppression direction can be adjusted. Furthermore, for large-scale dust suppression, the angle of the water guide pipe needs to be adjusted continuously, which is rather inconvenient. Moreover, the water and gas are directly connected to the conduit through the connecting pipe, so that impurities in the water easily block the two-fluid nozzle, thus affecting the dust suppression effect.

[0005] To achieve the object of the present utility model, the technical solution adopted by the present utility model is as follows: A dual-fluid spray dust suppression device is designed, including a mounting frame.

The inner sides of the two gear rings are fixedly connected with the connecting shafts through connecting plates. A U-shaped frame is sleeved on the outer side of the connecting shaft on one side of the middle conduit. Rack bars are fixedly connected to both ends of the U-shaped frame close to the two gear rings. The two rack bars are respectively in contact with the two gear rings.

[0006] One side of the mounting frame is penetrated by a screw rod. The screw rod is threadedly connected to the mounting frame. One side of the U-shaped frame is fixedly connected with a fixing plate. One end of the screw rod is rotatably connected to the surface of the fixing plate. A limiting groove is formed at one end of the U-shaped frame. A limiting block is slidably connected in the limiting groove, and the limiting block is fixedly connected to the inner side of the mounting frame.

[0007] Preferably, a mounting pipe is installed at the rear end of the mounting frame. A water inlet pipe is communicated between the mounting pipe and the conduit. A connecting pipe is communicated with the top of the mounting pipe. A filter disc is installed inside the connecting pipe.

[0013] 2. By combining the connecting pipe, the filter disc, the installation pipe and the water inlet pipe, the present utility model connects the connecting pipe with an external water pipe. When water from the external water pipe flows into the installation pipe, the filter disc filters the water, thus preventing impurities in the water from clogging the dual-fluid nozzle and affecting dust suppression. Moreover, when the external water pipe is disassembled, it is convenient to clean the impurities filtered on the filter disc. BRIEF DESCRIPTION OF THE DRAWINGS
