Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction systems, in particular to an automatic backwashing dry mist dust reduction host machine. Background Art

[0002] In many fields such as industrial production, solid materials are prone to generate a lot of dust during mining, loading and unloading, and transportation. These dusts will float in the working environment of production operations, affecting normal operations. Moreover, workers working in a dusty environment for a long time will seriously affect their physical and mental health. At the same time, in some industries, such as coal, metal and other mining industries, dust is very likely to cause explosions and other dangers, posing a huge threat to safe production.

[0003] As one of the main dust suppression facilities, the dry fog dust suppression system mainly includes water source, air source, booster, controller (also called host) and nozzle. The principle is to spray water from the nozzle in the form of mist through boosting, and the water mist condenses into agglomerates when it encounters dust and then settles to achieve the purpose of dust suppression.

[0004] The main unit is equipped with a water control valve and an air control valve, and the connecting parts of the two are located outside the main unit, connected to the water pipe and the air pipe to control the switch of the water and air circuits. The connecting parts exposed to the outside are very easy to be touched during the installation of the main unit or during the use of the main unit, causing damage to the connecting parts or the control valve as a whole, affecting the normal use of the dry fog dust suppression system.

[0013] In the waterway, a filter is usually installed on the water inlet pipe to filter dirt in the water to avoid clogging the nozzle. The sewage control valve is used to discharge the dirt filtered out by the filter. The upper end of the sewage pipe connector is connected to the filter through a pipe, and the lower end discharges the sewage into the sewer through a pipe.

[0014] In order to facilitate the arrangement of pipelines, the water circuit control valve, the gas circuit control valve and the sewage control valve are distributed laterally on the rear side wall of the first box body.

The upper and lower edges of the rear side plate of the second box body are vertically protruded with mounting ears.

[0019] In this way, not only can a stronger supporting force be provided for the abutting plate, but also materials can be saved.

[0020] In the present application, the first box body and the second box body are fixed to each other by means of a locking member, so that the first box body can be flipped over at any time to inspect and install the water pipe connector, the air pipe connector and the connected pipelines.

[0021] A box cover is hinged at the front end of the first box body, and a display unit is provided on the box cover, which is electrically connected to the control unit and is used to display the control conditions of the water circuit control valve and the gas circuit control valve, such as water pressure, flow rate, flow rate, etc.

[0034] The upper and lower side walls of the second box body 2 are provided with pipeline openings 21 at positions corresponding to the water pipe connector 11 and the air pipe connector 12, through which the water pipe and the air pipe are inserted and extended;

[0035] A control unit 3 is disposed in the first box body 1 , and the water circuit control valve and the gas circuit control valve are both electrically connected to the control unit 3 .

[0036] The detailed description is as follows:

[0037] The water pipe connector 11 and the air pipe connector 12 have the same shape but different uses. Both are T-shaped three-way fittings, and a valve core for controlling the pipeline switch is arranged inside. The water circuit control valve and the air circuit control valve also include a controller, which is located in the first box body 1 and is respectively connected to the water pipe connector 11 and the air pipe connector 12, and is used to control the operation of the valve core in the water pipe connector 11 and the air pipe connector 12.

[0038] The lower end of the water pipe connector 11 is connected to the water inlet pipe, the other end of the water inlet pipe is connected to a water source, such as a water tank, and the upper end of the water pipe connector 11 is connected to the water outlet pipe, the other end of the water outlet pipe is connected to the nozzle.

[0039] The lower end of the air pipe connector 12 is connected to the air inlet pipe, and the other end of the air inlet pipe is connected to the air source, such as a gas tank. The upper end of the water pipe connector 11 is connected to the air outlet pipe, and the other end of the air outlet pipe is connected to the nozzle.

[0040] Among them, the water outlet pipe and the air outlet pipe will first converge before being connected to the nozzle, and then be connected to the nozzle in a unified manner so that water can be sprayed out of the nozzle in a mist form.

[0041] The first box body 1 and the second box body 2 are both boxes with front openings. The first box body 1 and the second box body 2 have the same length and height. The rear edge of one side of the first box body 1 and the front edge of one side of the second box body 2 are connected by a hinge.

[0042] The front end of the first box body 1 is hinged with a box cover 4, which covers the front end of the first box body 1. The box cover 4 and the first box body 1 have the same length and height, and the rear edge of one side of the box cover 4 is connected to the front edge of one side of the first box body 1 through a hinge.

[0043] The hinged positions of the box cover 4 and the first box body 1 as well as the first box body 1 and the second box body 2 are located on the same side of the main machine, which is the left side in this embodiment.

[0044] After the main unit is installed, it is necessary to lock the first box body 1 and the second box body 2 together, and lock the box cover 4 on the first box body 1. To this end, in this embodiment, the first box body 1 and the second box body 2 are locked to each other by a locking member, and the box cover 4 is fixed to the first box body 1 by screws. It should be understood that the box cover 4 can also be locked with the first box body 1 by a locking member to facilitate the opening and closing of the box cover 4.

[0045] By means of the lock, the first box body 1 can be easily turned over at any time to inspect and install the water pipe connector 11, the air pipe connector 12 and the connected pipelines.

[0046] Furthermore, the main unit of this embodiment is also provided with a sewage control valve, which is arranged on the rear side wall of the first box body 1. The sewage control valve includes a sewage pipe connector 13 extending out of the rear side wall of the first box body 1 and a controller located in the first box body 1. The structural shape of the sewage control valve is the same as that of the water circuit control valve and the gas circuit control valve, and will not be repeated.

[0047] The controller controls the operation of the valve core in the sewage pipe connector 13 to control the switch of the sewage pipe. The sewage pipe connector 13 extends into the second box body 2. The lower side wall of the second box body 2 is also provided with a pipeline opening 21 corresponding to the sewage control valve for the sewage pipe to pass through.

[0048] In this embodiment, all pipeline openings 21 are U-shaped notches so that the pipeline can slide into the pipeline openings 21 from the openings of the pipeline openings 21 .

[0049] Specifically, in the waterway, a filter 5 is provided on the water inlet pipe to filter dirt in the water to avoid clogging the nozzle. The sewage control valve is used to discharge the dirt filtered out by the filter 5. The upper end of the sewage pipe connector 13 is connected to the filter 5 through a pipeline, and the lower end discharges the sewage into the sewer through a pipeline. The controller regularly switches the valve core in the sewage pipe connector 13.

[0050] In this embodiment, in order to facilitate the arrangement of pipelines, the water circuit control valve, the gas circuit control valve and the sewage control valve are distributed side by side and laterally on the rear side wall of the first box body 1.
