Description

A dust removal device with an orifice Technical Field

[0001] This utility model relates to the field of orifice dust removal technology, specifically an orifice dust removal device. Background Technology

[0002] In mining operations, when compressed air is used to remove dust during drilling operations in coal and rock masses, a large amount of drill cuttings are generated. These drill cuttings contain a large amount of fine dust. This fine dust is carried into the drilling work space by the compressed air that discharges the drill cuttings, seriously polluting the working environment. Therefore, dust removal equipment is needed to remove the dust.

[0003] For example, announcement number CN222879712U, entitled "A Dust Removal Device for Coal Mine Orifices," includes a blowout preventer, a first suction pipe, a second suction pipe, and a dust removal mechanism. This utility model involves installing a blowout preventer on the coal wall, with a dust outlet pipe at the top and a slag discharge pipe at the bottom. A first and second suction pipe are connected to the dust outlet pipe and the slag discharge pipe, respectively, and a dust outlet device is connected to the tail ends of both pipes. During use, the dust outlet device creates a negative pressure inside both the first and second suction pipes, allowing for simultaneous extraction of dust from both pipes.

[0004] However, the existing orifice dust removal devices mentioned above cannot effectively suppress dust dispersion by simply sucking up dust, resulting in dust residue and affecting the dust removal effect. Therefore, they do not meet the current needs, and an orifice dust removal device is proposed. Summary of the Invention

[0005] The purpose of this utility model is to provide an orifice dust removal device to solve the problem mentioned in the background art that the existing orifice dust removal devices, when used, cannot effectively suppress the scattering of dust by simply sucking up dust, resulting in dust still easily remaining and affecting the dust removal effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an orifice dust removal device, comprising: a platform, a fan installed on the top of the platform, one end of the fan connected to a post-treatment box via a pipeline, a water collection assembly disposed below the post-treatment box, the other end of the fan connected to an inclined guide pipe via a pipeline, a slag receiving assembly disposed at the bottom of the inclined guide pipe, a spray dust suppression assembly installed on one side of the platform, and the water outlet of the spray dust suppression assembly connected to the post-treatment box and the inclined guide pipe via pipelines respectively.

[0007] Preferably, the dust suppression spraying assembly includes a water storage tank, a pressure pump is installed above the water storage tank, a control valve is installed at the outlet of the pressure pump, a first delivery pipe and a second delivery pipe are respectively provided at both ends of the control valve, an atomizing nozzle is installed at one end of the second delivery pipe, and the atomizing nozzle is located inside an inclined guide pipe.

[0008] Preferably, a nozzle is provided at the lower end of the first delivery pipe, and the nozzle is located at the top inside the post-processing box.

[0009] Preferably, the slag receiving assembly includes a slag receiving box, the upper end of which is provided with a slag receiving pipe, and the slag receiving box is connected to the lower bottom of an inclined guide pipe through the slag receiving pipe.

[0010] Preferably, the water collection assembly includes a water collection tank, and a drain outlet is provided on the outer wall of the water collection tank.

[0011] Preferably, the water collection tank is provided with a limiting ring inside, a stuffing box is installed above the limiting ring, and a filter disc is provided at the bottom of the stuffing box.

[0012] Preferably, the outer walls on both sides of the post-treatment box are respectively provided with connection ports and exhaust ports, and the connection ports are connected to the fan through pipelines.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, the inclined guide pipe is used to be inserted into the orifice. The fan is connected to the inclined guide pipe. When the fan is turned on, the gas in the orifice is drawn to the outside through the connection at the inclined guide pipe. On this basis, the pressurized pump delivers water from the water storage tank to the second delivery pipe. The second delivery pipe sprays the orifice with atomizing nozzles to suppress dust in the orifice. The generated sewage falls down the inclined guide pipe into the slag receiving assembly for collection. When the fan pulls the gas outward, the gas enters the post-treatment box before being discharged. Water is delivered to the nozzle through the first delivery pipe. The nozzle sprays the gas drawn to the post-treatment box below, which achieves the effect of secondary treatment of the dust-containing gas. The treated sewage falls into the water collection assembly below. The above structure can effectively remove dust from the orifice and treat the discharged dust-containing gas, thus improving the dust suppression effect.

[0015] (2) In this utility model, the slag receiving box is connected to the inclined guide pipe through the slag receiving pipe, so that the heavier impurities and wastewater at the inclined guide pipe can be guided into the slag receiving box, which is convenient for users to collect in a centralized manner.

[0016] (3) In this utility model, the spray water falls downward into the packing box, which is used to place the packing material. The packing material filters the impurities in the sewage. The adsorbed water falls into the water collection tank through the filter plate and is discharged through the drain outlet. The limiting ring is set so that the packing box can be placed on top, making it convenient for users to take and replace the packing material. The above structure can treat and collect the sewage generated at the post-treatment tank. Attached Figure Description
