Technical Field
[0001] The utility model relates to the technical field of physical ore dressing, in particular to a wet dust removal system. Background Art
[0002] During the crushing, screening and operation process of the raw ore, dust is inevitably generated due to collision, extrusion and impact. In particular, the amount of dust generated at the crusher, vibrating screen, belt transport drop point, etc. is large and paroxysmal, becoming the main dust source in the crushing section. During normal production, dust fills the entire production workshop, causing a very great impact on the company's production and employee health.
[0003] The current ore dressing system uses dry dust removal for dust removal. The existing dust collectors have insufficient dust suction positions and insufficient suction capacity, and cannot effectively capture and filter the generated dust, which affects the cleanliness and air quality of the entire production environment. Moreover, if the dust removal effect is enhanced simply by adding dust suction pipes or replacing larger dust collectors, the cost will increase significantly, which is not conducive to the economic benefits of the enterprise.
[0004] Therefore, it is necessary to propose a wet dust removal system. Utility Model Content

This method combines the principle of wet dust removal and significantly improves the dust removal efficiency.
[0006] The technical solution adopted by the utility model to solve its technical problems is:
[0007] A wet dust removal system comprises a water tank and a dust collector, wherein the water in the water tank is transported to a spraying position through a spraying pipe, and the dust collection pipe of the dust collector is arranged on the dust collection position;

[0011] Preferably, the spray pipe further includes a third spray pipe, and the third spray pipe is arranged on the No. 2 belt; the dust suction pipe includes a third dust suction pipe, and the third dust suction pipe is arranged between the No. 2 belt and the screening machine.
[0012] Preferably, the spray pipe further includes a fourth spray pipe, and the fourth spray pipe is arranged between the third belt and the fine crusher.
[0013] Preferably, the spray pipe further includes a fifth spray pipe, and the fifth spray pipe is arranged on the eighth belt.
[0014] Preferably, the water tank is a high-level water tank.
[0015] Preferably, the water tank transports the water in the water tank from the spray pipe to the spray position through a water pump.
[0016] Preferably, the spray pipe is connected to a spray head.
[0017] Preferably, the dust collector is a pulse jet dust collector.
[0018] The beneficial effects of the utility model are:
[0019] 1. The wet dust removal system described in this application has a spraying position set in front of or above the dust collection position. By setting a spray pipe at a key process point, the water in the water tank is used for spraying to effectively wet and capture dust particles in the air, and then the dust is sucked through the dust collector to achieve the dust removal effect. This method combines the principle of wet dust removal and significantly improves the dust removal efficiency.
[0020] 2. The wet dust removal system described in this application can wet the material surface and reduce the dust generated during the material transportation and crushing process by setting up a spraying position for wet dust removal in the front process. In particular, the wet dust removal method can effectively settle larger dust particles. In the back process, the dust suction position can be set up for dry dust removal, which can capture smaller dust particles suspended in the air and further improve the dust removal effect.
[0021] Moreover, the wet dust removal system described in this application ensures the continuity and efficiency of dust removal by rationally arranging the spraying and dust collecting positions. The wet dust removal in the previous process creates favorable conditions for the dry dust removal in the subsequent process. The two cooperate with each other to achieve efficient dust treatment.

[0030] like Figure 1-2 As shown, a wet dust removal system includes a water tank 1 and a dust collector 2, the water in the water tank 1 is transported to the spraying position through a spray pipe 11, and the dust suction pipe 21 of the dust collector 2 is arranged on the dust suction position;
[0031] The spraying position is arranged in front of or above the dust collecting position.
[0032] Specifically, the wet dust removal system is arranged on a mineral processing system, and the mineral processing system comprises:
[0033] A vibrating feeder, wherein the discharge port of the vibrating feeder is connected to a No. 1 belt, and the No. 1 belt is connected to a No. 1 screening machine;
[0034] The No. 1 screening machine is connected to the belt feeder, the belt feeder is connected to the coarse crusher, the discharge port of the coarse crusher is connected to the No. 2 belt, the No. 2 belt is connected to the No. 2 screening machine, the No. 2 screening machine is connected to the No. 3 belt and the No. 6 belt, the No. 3 belt is connected to the fine crusher; the discharge port of the fine crusher is connected to the No. 2 belt;
[0035] The No. 2 screening machine is connected to the No. 8 belt, and the No. 8 belt is connected to the stockpile yard.
[0036] Specifically, the spray pipe 11 includes a first spray pipe 1101, and the first spray pipe 1101 is arranged on the first belt; the dust suction pipe 12 includes a first dust suction pipe 2101, and the first dust suction pipe 2101 is arranged between the first belt and the first screening machine.
[0037] Therefore, the material on the No. 1 belt is sprayed through the first spray pipe to wet the material surface and reduce the dust generated during the transportation of the material; the dust generated between the No. 1 belt and the screening machine is captured through the first dust suction pipe to prevent the dust from spreading into the environment.
[0038] Specifically, the spray pipe 11 further includes a second spray pipe 1102, and the second spray pipe 1102 is arranged on the belt feeder; the dust suction pipe 21 includes a second dust suction pipe 2102, and the second dust suction pipe 2102 is arranged on the discharge port of the coarse crusher.
[0039] Therefore, the second spray pipe is used to spray the material on the belt feeder to further reduce the dust during the material transportation process, and at the same time wet the material to prepare for the subsequent crushing process. The second dust suction pipe is used to capture a large amount of dust generated at the discharge port of the coarse crusher, because a large amount of dust will be generated by the collision and extrusion of the material during the crushing process.
[0040] Specifically, the spray pipe further includes a third spray pipe 1103, and the third spray pipe 1103 is arranged on the No. 2 belt; the dust suction pipe includes a third dust suction pipe 2103, and the third dust suction pipe 2103 is arranged between the No. 2 belt and the No. 2 screening machine.
[0041] Therefore, the third spray pipe is used to spray the material on the No. 2 belt to moisten the material and reduce the dust during the belt transportation process, in preparation for subsequent screening or transportation. Therefore, the third dust suction pipe is used to capture the dust generated between the No. 2 belt and the No. 2 screening machine to prevent the dust from interfering with the screening process or further spreading.
[0042] Specifically, the spray pipe further includes a fourth spray pipe 1104, and the fourth spray pipe 1104 is arranged between the third belt and the fine crusher. Therefore, the material before fine crushing is sprayed through the fourth spray pipe, the material is moistened and the dust generated during the fine crushing process is reduced, the working environment is improved and the harm of dust to the health of employees is reduced.
[0043] Specifically, the spray pipe also includes a fifth spray pipe 1105, and the fifth spray pipe 1105 is arranged on the eighth belt.
[0044] Therefore, the fourth spray pipe is used to carry out the final spraying of the materials on the No. 8 belt to ensure that the materials reach a certain humidity before being transported to the yard and reduce the dust generated during the yard process.
[0045] The locations of the first spray pipe, the first dust suction pipe, the second spray pipe, the second dust suction pipe, the third spray pipe, the third dust suction pipe, the fourth spray pipe and the fifth spray pipe are not determined randomly, but are determined based on the dust generated during the crushing, screening and operation of the raw ore and the distribution characteristics of the dust. Such a layout can maximize the effect of the wet dust removal system, improve dust removal efficiency, reduce the impact on the environment, and protect the health of employees.
[0046] Specifically, the water tank 1 is a high-position water tank 1.
[0047] Specifically, the water tank 1 transports the water in the water tank 1 from the spray pipe to the spray position through the water pump 12.
[0048] Specifically, the spray pipe is connected to the spray head.
[0049] Specifically, the dust collector 2 is a pulse-jet dust collector 2 .
[0050] like Figure 1-2 As shown in the figure, the specific operation process of a wet dust removal system is as follows:
[0051] When the system starts running, the water in the water tank is transported to each spray pipe through the water pump. These spray pipes are set at different process points according to the system layout, such as the No. 1 belt, belt feeder, No. 2 belt, No. 3 belt and No. 8 belt. When the water is transported to the spray position through the spray pipe, the spray head will spray water to wet and capture dust particles in the air.
[0052] At the same time, the dust collection pipe of the dust collector is set on the dust collection position, which is usually located below or behind the spraying position to capture the residual dust that is not removed by the spraying. The dust collection pipe introduces the dust-laden gas into the dust collector, and through the filtering mechanism of the dust collector, such as the interception and screening effect of the filter bag surface, the dust particles are further captured, so that the passing air is purified.
[0053] During the operation of the entire wet dust removal system, wet dust removal and dry dust removal are combined to form a continuous and efficient dust removal process. Wet dust removal wets the dust particles by spraying, causing them to settle or be captured, while dry dust removal further removes residual dust through the filtering effect of the dust suction pipe and dust collector.
[0054] In addition, the system is flexible and can adjust the number and layout of spray pipes and dust suction pipes according to actual production conditions and needs to adapt to different dust removal requirements.
[0055] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the protection scope of the present invention.
