[0026] The present invention will be further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are merely descriptive and not restrictive, and the protection scope of the present invention cannot be limited thereto.

[0027] A funnel spray dust suppression device, see attached Figure 1 , 2 As shown, it includes a bucket body 1, a stand 7, a water dividing ring 4, a water divider 5, a hose 3 and a nozzle 2. The stand 7 is a rectangular cubic frame structure, and a roller 8 is installed at the lower end of the stand 7 so that it can move; the bucket body 1 is fixedly installed on the upper part of the stand 7, and the bucket body 1 is a square bucket with a four-sided pyramid structure with a large opening at the upper end and a small opening at the lower end. A water dividing ring 4 is fixedly installed on the outer periphery of the middle part of the bucket body 1. The water dividing ring 4 is an annular hard water pipe with a cavity inside. A plurality of water dividers 5 are arranged at intervals on the water dividing ring 4, and each water divider 5 is connected to a hose 3. A high-pressure water nozzle 2 is installed at the other end of the short pipe, and the water divider 5 is connected to the inner cavity of the water dividing ring 4. The high-pressure water in the water dividing ring 4 is sprayed out through the nozzle 2;

[0028] The water dividing ring 4 is externally connected to a water pump through a water pipe, and the water pump continuously delivers high-pressure water to the water dividing ring 4 .

[0029] In this embodiment, there are eight nozzles 2, four of which are arranged at the opening at the upper end of the bucket body 1, and the four nozzles 2 at the upper end are respectively arranged in the middle of the four sides of the entrance of the bucket body 1, and the ends of the nozzles 2 are embedded and fixed on the side walls of the bucket body 1, and the water spraying directions of the four nozzles 2 at the upper end are all horizontally toward the center direction of the bucket body 1; the other four nozzles 2 are arranged at the lower outer part of the discharge port 6 at the lower end of the bucket body 1, and the four nozzles 2 at the lower end are arranged at the corresponding positions of the four corners of the discharge port 6, and the water spraying direction of the lower nozzle 2 is inclined downward toward the center direction of the bucket body 1.

[0030] See attached Figure 3 , 4As shown, in order to realize automatic control of water conservation, an infrared sensing device 9 is installed on one side of the upper opening of the bucket body 1. The specific structure is that a vertically arranged fixing rod 94 is fixedly installed on the upper end of the bucket body 1, and an angle adjuster 93 is installed on the upper end of the fixing rod 94. An infrared probe 92 is installed on the angle adjuster 93. The infrared probe 92 is connected to an external electric control box through a power cord 95. The infrared probe 92 detects a signal of the approaching material and transmits it to the electric control box. The electric control box sends an execution control signal to start the water pump, so that the sprinkler 2 starts to spray water.

[0031] In order to prevent the infrared probe 92 from being damaged, a protective cover 91 is installed above the infrared probe 92 , and the protective cover 91 is fixedly connected to a fixing rod 94 .

[0032] According to the operation characteristics of the ore hopper at the wharf, this equipment adopts the working mode of indirect water spraying and dust removal. When the grab bucket approaches the hopper and starts to discharge materials, the infrared detector on the top of the hopper senses the signal transmitted by the grab bucket and controls the nozzle 2 to start water spraying and dust removal. The water spraying and dust removal stops after the grab bucket finishes discharging and leaves.

[0033] According to the above characteristics, there are two control modes for this dust suppression equipment, which are automatic control water spraying device and manual remote control water spraying device. The automatic control water spraying device is to install an infrared detector induction switch on the top of the funnel. When the grab bucket moves to the top of the funnel, the detector senses that the grab bucket is close to control the high-pressure water pump to start the water supply through the pipeline to the nozzle 2 to spray water. The other system is to directly control the water pump by remote control to start the water supply. Automatic control is the main control mode, and the manual remote control system is the backup control mode. Ensure the normal operation of the dust suppression equipment is safe and reliable.

[0034] See attached Figure 5 As shown, the overall water connection structure of the spray device includes a water storage tank, a water pump, a main water pipe, a water distribution pipe, a nozzle and a plurality of stop valves.

[0035] The water storage tank is connected to the water pump through the main water pipe, and the water pump is connected to multiple water distribution pipes through the main water pipe. Each water distribution pipe is connected to a nozzle, and each water distribution pipe is installed with a stop valve.

[0036] A filter device is connected to the main water pipe between the water storage tank and the water pump, and another filter device is connected to the main water pipe between the water pump and the water distribution pipe to ensure the cleanliness of the water and prevent the nozzle from being blocked.

[0037] A stop valve is installed on the main pipe corresponding to the water outlet of the water tank to control the switch of the entire water circuit.

[0038] The water pump is connected to a stop valve to control the switch of the water pipe where the water pump is located.

[0039] The main water pipe is connected to an auxiliary water pipe in parallel with the water pump. The auxiliary water pipe is equipped with a stop valve and a pressure gauge. When the water pressure in the water tank is high, the auxiliary main water pipe can be opened to supply water.

[0040] The water pump used in this embodiment has a power of 7.5KW, a flow rate of 10 tons / hour, and a head of up to 160 meters. This system is a high-pressure water spraying system and the number of nozzles is reduced from the conventional 28 nozzles to 12 nozzles. The reduction in the number of nozzles means a reduction in equipment maintenance and also reduces water resource consumption. The water pump is a high-pressure pump. The increase in water spray pressure makes the atomization of the water sprayed by the nozzle more complete and the dust prevention effect is also better. This device can remove dust fully automatically, and can remove dust normally without manual operation. The effect is obvious and there is no obvious dust visually. This equipment can be used normally in an environment with a wind speed of less than 55m / s in the design working conditions, and its dust removal effect meets the environmental protection requirements of the national environmental monitoring department for the dock.

[0041] The water pump of this equipment is a high-pressure water pump (water pump flow rate 10 tons / hour, head up to 160 meters) and is equipped with a frequency converter. The drainage pressure of the water pump can be controlled according to the size of dust raised by different goods. The advantage of the frequency converter controlling the water pump is to reduce the normal start-stop current of the water pump and avoid the impact of instantaneous current when the water pump starts and stops.
