Description

Technical Field

[0001] The utility model belongs to the technical field of mine dust suppression equipment, and particularly relates to an ultrasonic dry fog dust suppression device for mines. Background Art

[0002] Coal mining is accompanied by a large amount of dust, and dust concentration is a parameter that must be strictly controlled in the mine. Coal mining generates a large amount of coal dust during excavation, loading, transportation, and unloading processes. This dust not only affects workers' health and reduces their visibility, but also can cause explosions when dust concentration reaches a critical value. Therefore, dust suppression devices are essential equipment in mines. Current dust suppression devices generally consist of a main unit and a dust suppression box. The main unit is equipped with an air filter and a water filter to supply air and water to the dust suppression box. Dust suppression devices are required in the main passages within the mine and at the excavation site, and their continuous operation controls dust concentration. Because the filter element in the water filter easily accumulates a large amount of impurities and can only be replaced for continued use, the main unit is often equipped with a pair of water filters that rotate and use multiple valves to achieve backwashing. However, this main unit structure has relatively high production costs, and the frequent replacement of the filter element of a single water filter is cumbersome and requires high maintenance costs.

[0003] In view of the above situation, it is necessary to design a mining ultrasonic dry mist dust suppression device with simple structure, low cost and single water filter backwash function. To this end, the applicant has made a useful design, and the technical solution to be introduced below is produced in this context. Utility Model Content

[0004] The task of the utility model is to provide an ultrasonic dry mist dust suppression device for mining, which helps to improve the main structure of the dust suppression device so that a single water filter can achieve backwashing function through simple operation, which is beneficial to reducing the number of water filters and valve bodies in the main unit to save costs.

[0005] The task of the utility model is accomplished in this way. A mining ultrasonic dry fog dust suppression device comprises a chassis, an air filter arranged in the chassis, a water filter arranged in the chassis and a group of dust suppression boxes connected in series and connected to the air filter and the water filter. The chassis body is formed with an air inlet interface, a water inlet interface, an air outlet interface and a water outlet interface, and is characterized in that: an upper water outlet is formed above the water filter, and a side water outlet is formed on the side.

A filter sleeve is provided in the water filter for separating the upper water outlet from the side water outlet. The lower end of the water filter passes through the chassis and is formed with a drainage interface. The three-way ball valve realizes conduction between the water inlet interface and the upper water outlet and conduction between the water inlet interface and the side water outlet respectively.

[0006] In a specific embodiment of the present invention, the chassis is provided with a chassis cover, which is hinged to the chassis body via a hinge.

[0008] In another specific embodiment of the present invention, the water filter is fixed in the chassis by a clamp.

[0009] In another specific embodiment of the present invention, the three-way ball valve is composed of a water inlet pipe connected to the water inlet interface, a transition pipe connected to the pressure regulating valve and an upper water-passing end connecting pipe connected to the upper water-passing end. A three-way joint is provided on the transition pipe, and the two ends of the three-way joint are connected to the transition pipe, and the third end is connected to the side water-passing end through a side water-passing end connecting pipe.

[0010] In another specific embodiment of the present invention, one end of the pressure regulating valve is connected to the three-way ball valve, and the other end is connected to the water outlet interface through a water outlet pipe, and a water pressure gauge is provided on the water outlet pipe.

[0011] In another specific embodiment of the present invention, the dust suppression box includes an air box, a water box and a group of connecting seats and a plurality of ultrasonic atomizing nozzles respectively installed on the connecting seats. One end of the connecting seat is connected to the air box, and the other end is installed and connected to the ultrasonic atomizing nozzle. The middle part of the connecting seat is connected to the water box.

[0012] In a more specific embodiment of the present invention, in a group of dust suppression boxes, the ventilation boxes between two adjacent dust suppression boxes are connected to each other to form a series structure, and the water boxes between two adjacent dust suppression boxes are connected to each other to form a series structure; one end of the ventilation box and the water box of one of the dust suppression boxes are respectively connected to the air outlet interface and the water outlet interface on the chassis.

[0013] In a further specific embodiment of the present invention, a normally closed valve body is connected to the end of the drainage interface, and the normally closed valve body is opened when backwashing is required.

[0014] After adopting the above structure, the utility model has the beneficial effect: since a filter sleeve is arranged in the water filter and the direction of water flowing through the filter sleeve is switched by cooperating with the three-way ball valve and the pressure regulating valve, the single water filter can complete the functions of filtering and backwashing through simple operation, which greatly reduces the number of water filters and supporting valve bodies, and effectively saves manufacturing costs and maintenance costs.
