Description

Technical Field

[0001] The present application relates to the technical field of dust removal equipment, and in particular to an atomizing dust suppression device for a discharge port of a mine crusher. Background Art

[0002] During the unloading process of the mine car at the discharge port of the mine crusher, a large amount of dust will be generated. In order to solve the above problem, the traditional method is to use a bag dust collector to reduce dust. The bag dust collector is a filtering dust removal equipment based on the filtering principle, which uses fiber or inorganic fiber filter cloth to filter out dust in the gas. When the dust-laden gas enters the dust collector, most of the larger dust particles are intercepted under the action of gravity and inertia, and the fine dust is adsorbed on the surface of the bag to form a dust layer, thereby achieving the purpose of purifying the air.

[0003] However, the filter bags of bag filters are prone to sticking and clogging, and need to be cleaned frequently to ensure their performance. The cleaning process is prone to causing secondary dust problems. Utility Model Content

[0032] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technical personnel.

[0033] Embodiment 1:

[0034] See also Figure 1 , Figure 2 and Figure 3 , an atomizing dust suppression device for a discharge port of a mine crusher, comprising a discharge port 1, and brackets 2 installed on both sides and the upper side of the discharge port 1, the atomizing dust suppression device for the discharge port of a mine crusher also includes:

[0035] A gas pipeline 3, on which an air switch valve 4 and an air regulating valve 5 are provided;

[0036] A water delivery pipeline 6, on which a liquid switch valve 7 and a hydraulic regulating valve 8 are provided;

[0037] The spray pipe 9 is fixed on the bracket 2, and its two ends are respectively connected to the gas pipeline 3 and the water pipeline 6;

[0038] The air atomizing nozzle 10 is installed on the spray pipe 9, and at least one air atomizing nozzle 10 is provided.

[0039] Specifically, the air switch valve 4 is installed on one end close to the air inlet of the gas pipeline 3 to control the circulation and cutoff of air. The air regulating valve 5 is installed on the end away from the air inlet of the gas pipeline 3. It uses compressed air as power to achieve switch quantity or proportional regulation. It can receive the control signal of the industrial automation control system to complete the regulation of various process parameters such as air flow, pressure, temperature, etc. in the gas pipeline 3.

[0040] The liquid switch valve 7 is installed on one end close to the water inlet of the water pipeline 6 to control the flow and cutoff of the water flow. The hydraulic regulating valve 8 is installed on one end away from the water inlet of the water pipeline 6 to receive the control signal of the industrial automation control system to complete the adjustment of various process parameters such as water flow, pressure, temperature, etc. in the water pipeline 6.

[0041] The spray pipe 9 is fixed on the bracket 2 and distributed on both sides and the upper side of the discharge port 1. A plurality of air atomizing nozzles 10 are installed at equal intervals on the spray pipe 9. The number of air atomizing nozzles 10 is reasonably arranged according to the size of the discharge port 1. The air atomizing nozzles 10 are installed at a certain angle, and the dust suppression direction is gathered toward the middle of the discharge port 1. Under the air-water mixed pressure of the upper air atomizing nozzle 10, the dust is suppressed at the bottom of the discharge port 1. In this embodiment, 60 air atomizing nozzles 10 are provided to meet the dust suppression requirements.

[0042] When a mine car enters the discharge port 1 to prepare for unloading, the air switch valve 4 and the liquid switch valve 7 are started to allow air and water to enter the air pipeline 3 and the water pipeline 6 respectively. At the same time, the air regulating valve 5 is adjusted to keep the air flow and pressure within a reasonable range, and the hydraulic regulating valve 8 is adjusted to keep the water flow and pressure within a reasonable range. The air and water flow are gathered in the spray pipe 9 and then enter the air atomizing nozzle 10. The air atomizing nozzle 10 is a device that can spray liquid into atomization and evenly suspend it in the air. Its working principle is to squeeze the internal liquid into the nozzle through internal pressure. An iron sheet is placed inside the nozzle. The high-speed flowing liquid hits the iron sheet and forms atomized particles with a diameter of about 15-60 microns after rebounding. The particles are sprayed out through the nozzle outlet. The atomized particles act on the dust generated by the unloading, thereby achieving the effect of atomization and dust suppression.

[0043] In this embodiment, atomization dust suppression is used to replace the traditional bag dust collector. Since the atomization dust suppression device of the present application is mostly composed of pipes, the amount of dust accumulated on the pipes is small, so there is no need to frequently clean the device, and during the cleaning process, the amount of dust is small, and no secondary dust will be caused.

[0044] In this embodiment, the air atomizing nozzle 10 is a single nozzle, which uses less water, is energy-saving and environmentally friendly, and the water mist evaporates quickly. A small amount of water will not increase the water content in the material, and the impact on the downstream belt is minimal; the water mist produced by the air atomizing nozzle 10 is finer, has stronger adsorption capacity, is more environmentally friendly, and is fully atomized. The nozzle is not blocked, does not leak, and is automatically cleaned by internal rotation, and has strong durability. The appropriate spraying time can be set according to the actual application of the discharge port 1 to achieve the purpose of both dust reduction and not wetting the material.

[0045] Embodiment 2:

[0046] See also Figure 1 Based on the first embodiment, further and optionally, an air filter 11 is provided between the air switch valve 4 and the air regulating valve 5 .

[0047] Specifically, the air filter 11 is installed on the gas pipeline 3, and its two ends are respectively connected to the air switch valve 4 and the air regulating valve 5. The gas pipeline 3 is connected to a fan. The air entering from the air inlet of the gas pipeline 3 contains a certain amount of solid impurities, such as rust, sand, pipe sealant, etc. These solid impurities can easily cause the accuracy of the air regulating valve 5 to decrease or even damage it, and also cause the outlet of the air atomizing nozzle 10 to be blocked, shortening the service life of the air atomizing nozzle 10 or causing it to fail. By setting the air filter 11 to filter and remove dust and solid impurities in the air, making it clean air, thereby protecting the air regulating valve 5, ensuring its adjustment accuracy, and avoiding the outlet of the air atomizing nozzle 10 from being blocked.

[0048] Further and optionally, a liquid filter 12 is provided between the liquid switching valve 7 and the hydraulic regulating valve 8 .

[0049] Specifically, the liquid filter 12 is installed on the water supply pipe 6, and its two ends are respectively connected to the liquid switch valve 7 and the hydraulic regulating valve 8. The water flow entering from the water inlet of the water supply pipe 6 contains a certain amount of solid impurities, such as rust, sand, pipe sealant, etc. These solid impurities can easily cause the accuracy of the hydraulic regulating valve 8 to decrease or even damage it, and also cause the outlet of the air atomizing nozzle 10 to be blocked, shortening the service life of the air atomizing nozzle 10 or causing it to fail. By setting up the liquid filter 12 to filter and remove dust and solid impurities in the water, it is turned into a clean water flow, thereby protecting the hydraulic regulating valve 8, ensuring its adjustment accuracy, and avoiding the outlet of the air atomizing nozzle 10 from being blocked.

[0050] Further and optionally, one end of the water delivery pipeline 6 is connected to a water tank 13 , and a high-pressure plunger pump 14 is connected between the water tank 13 and the liquid switch valve 7 .

[0051] Specifically, the water tank 13 is used to store water and provide a water source for dust suppression operations. The high-pressure plunger pump 14 has the characteristics of high pressure and large flow, which can meet the power and flow requirements of the hydraulic system; secondly, the high-pressure plunger pump 14 has a compact structure and light weight, which is easy to install and maintain; finally, the high-pressure plunger pump 14 has a strong precision control capability, which can achieve accurate flow and pressure regulation, and improve the stability and reliability of the hydraulic system;

[0052] In this embodiment, a high-pressure plunger pump 14 is provided to allow the water in the water tank 13 to flow into the water supply pipe 6. Compared with traditional bag dust collectors, two-fluid sprays, and water sprays, only a small-power high-pressure plunger pump 14 is needed to achieve the desired effect, which is energy-saving and environmentally friendly.

[0053] Further and optionally, two sides of the discharge port 1 are provided with opposing infrared sensors for determining whether an object passes through the discharge port 1 .

[0054] The through-beam infrared sensor consists of two parts: a transmitter and a receiver. The transmitter is installed on one side of the discharge port 1, and the receiver is installed on the other side of the discharge port 1. The transmitter emits infrared signals, and the receiver receives these signals and converts them into electrical signals, which are then processed by the circuit.

[0055] When a minecart approaches a through-beam infrared sensor, the infrared signal will be reflected by the minecart back to the sensor receiver. The receiver will detect these reflected signals and convert them into electrical signals, and determine the distance and position of the object by measuring the intensity and time of the reflected signals, thereby determining whether a minecart has passed.

[0056] Further and optionally, the air switch valve 4 , the liquid switch valve 7 , the air regulating valve 5 , the hydraulic regulating valve 8 , the air filter 11 , the liquid filter 12 and the high-pressure plunger pump 14 are all controlled by the high-pressure micro-mist host 15 .

[0057] Specifically, the operation of the air switch valve 4, the liquid switch valve 7, the air filter 11, the liquid filter 12 and the high-pressure plunger pump 14 are controlled by the high-pressure micro-mist host 15, and the pressure and flow parameters of the air regulating valve 5 and the hydraulic regulating valve 8 are set and checked. By setting the high-pressure micro-mist host 15, the pressure and flow of the air flow and the water flow can be reasonably controlled according to the dust mist concentration generated by unloading, so as to improve the dust suppression efficiency.

[0058] Further and optionally, the air atomizing nozzle 10 is a pressure cone nozzle.

[0059] Specifically, the pressure cone nozzle can produce a solid cone spray shape, the spray area is square, and the droplet size is medium to large. It has a unique blade design inside, a large and smooth channel, so that the nozzle has the dual characteristics of not easy to clog and uniform atomization. It is very suitable for installation in places with covered rectangular spray areas, and the discharge port 1 in this embodiment is rectangular, and the pressure cone nozzle can adapt to this area well.

[0060] Further and optionally, the bracket 2 is made of C-shaped steel, and the gas pipeline 3, the water pipeline 6 and the spray pipeline 9 are all made of DN32 galvanized steel pipes.

[0061] Specifically, galvanized steel pipes have excellent corrosion resistance and durability, which can extend the service life of the pipeline; their surface is smooth, not easy to scale, easy to clean and maintain, and have good compressive strength and tensile strength, suitable for various pressure and temperature conditions;

[0062] In this embodiment, the air atomizing nozzle 10, the galvanized steel pipe and accessories are not easy to fall off, are corrosion-resistant, not easy to rust, and are durable.

[0063] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application; the dimensions of the drawings are not related to the specific objects, and the dimensions of the objects can be changed arbitrarily.
