Description

Technical Field

[0001] The present invention relates to the technical field of ore raw material crushing, and in particular to a dust removal device and a dust removal method for ore raw material crushing. Background Art

[0002] In the chemical industry, many useful ingredients of chemical products are derived from ores. For example, the preparation of phosphates, phosphate fertilizers and other phosphides requires phosphate rock as raw material. The phosphate rock is crushed, smelted and processed to eventually form the required chemical products.

[0003] Taking phosphate rock as an example (not limited to phosphate rock), the pulverization process of phosphate rock includes two stages: crushing and grinding. The crushing stage is to crush the 1500-350mm material to 350-100mm, then crush it to 100-40mm, continue to crush it to 30-10mm, and finally enter the grinding mill for grinding. Depending on the size of the original material, a two-stage, three-stage or four-stage crushing process can be selected. For example, if the particle size of the raw material of the phosphate ore is relatively small, the entire crushing process can be completed with a jaw crusher + grinding mill. Commonly used crushing equipment mainly includes jaw crusher, impact crusher, hammer crusher, cone crusher, gyratory crusher, roll crusher, etc.

[0004] In the crushing stage of phosphate ore, the crushing stage of phosphate ore usually includes the following steps: Coarse crushing: The phosphate ore is crushed for the first time using a jaw crusher or a gyratory crusher. Medium crushing: The coarsely crushed phosphate ore is sent to a cone crusher for medium crushing. Screening: The phosphate ore after medium crushing is screened using a circular vibrating screen or a linear vibrating screen to separate particles of different sizes. Fine crushing: The screened phosphate ore particles are sent to a grinding mill for fine crushing to achieve the required fineness. Depending on the situation, the crushing stage of phosphate ore may be adjusted according to the size and nature of the raw materials; at the same time, dust is generated in multiple steps of the crushing stage, but the most critical step is coarse crushing. Coarse crushing is the process of crushing large pieces of phosphate ore for the first time, usually using a jaw crusher or a gyratory crusher. Because the ore is broken into smaller particles during coarse crushing, the surface area is increased, allowing more dust to be released. Therefore, coarse crushing is one of the steps that causes the most dust in the entire crushing stage. In order to reduce the generation of dust, some measures can be taken, such as installing dust removal devices on the equipment and improving the operating environment.

[0005] The patent document with publication number CN217490218U discloses a dust removal device and valve for phosphate ore crushing, including a dust removal mechanism, a crusher is provided on the outer surface of the lower end of the dust removal mechanism, a feed port is provided on one side of the dust removal mechanism, a crushing assembly is provided inside the crusher, a discharge port and a support leg are provided on the outer surface of the lower end of the crusher, and the support leg is located on one side of the discharge port, and a vibration motor is provided on the outer surface of both sides of the discharge port. However, the traditional dust removal used in the coarse crushing of ore is mostly spray dust removal, and in the process of ore crushing, the dust floats in a wide range, and the atomizing nozzle cannot cover the dust diffusion area in all directions, resulting in poor dust removal effect. For example: in the coarse crushing of ore, a gyratory crusher is needed. When the ore blocks crushed by the gyratory crusher are fed, the raised dust is also scattered and floated, which is not easy to target dust reduction. Summary of the invention

[0006] The invention discloses a dust removal device and a dust removal method for ore raw material crushing, aiming to solve the technical problem that traditional dust removal for coarse ore crushing is mostly spray dust removal, and in the ore crushing process, the dust floats in a wide range or the atomizing nozzle cannot cover the dust diffusion area in all directions, resulting in poor dust removal effect.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A dust removal device for crushing ore raw materials, comprising two support platforms and a cement platform installed on the top of the two support platforms, a gyratory crusher body is installed at the bottom of the cement platform, a feed hopper is provided on the top of the gyratory crusher body, and the feed hopper is connected to the top outer wall of the cement platform, and also comprises: a spray dust reduction mechanism: the spray dust reduction mechanism is arranged just above the cement platform; a dust suction mechanism: the dust suction mechanism is located on the outside of the spray dust reduction mechanism, the dust suction mechanism comprises a cover plate arranged on one side of the top outer wall of the cement platform, fixing holes are provided on both sides of the top outer wall of the cover plate, dust suction hoods are installed on the inner walls of the two fixing holes, introduction hoppers are installed on the outer walls of both sides of the cement platform, air pumps are installed on the two introduction hoppers, and suction ports are connected to the inlet of the air pump. Pipe, mounting holes are provided on the outer walls on both sides of the cover plate, one end of the suction pipe is connected to the inner wall of the mounting hole, and the suction pipe is connected to the interior of the dust hood, and the outlet of the air pump is connected to the interior of the introduction bucket; Anti-diffusion mechanism: the anti-diffusion mechanism is located at the periphery of the dust suction mechanism, the anti-diffusion mechanism includes a water collecting box arranged on the outer wall of the bottom of the cover plate, and the outer wall of the bottom of the water collecting box is provided with a second atomizing nozzle distributed at an equal distance, and the bottom of the atomizing nozzle is provided with a spray hole, and shunt pipes are installed on the inner walls on both sides of the cover plate, and the two shunt pipes are respectively used to connect the spray dust reduction mechanism and the water collecting box, and a notch is provided on the outer wall of one side of the cover plate; Guiding and cleaning mechanism: the guiding and cleaning mechanism is arranged on both sides of the outer wall of the top of the cement platform.

[0009] In this solution, the dust raised during the crushing process of ore raw materials is effectively guided by connecting the dust suction mechanism with the spray dust reduction mechanism. The dust after guidance is, on the one hand, more easily cleaned by the spray dust reduction mechanism. On the other hand, the dust that is not cleaned in time can be adsorbed into the inside of the suction pipe and finally cleaned up by the guiding and cleaning mechanism, which effectively solves the problem of poor traditional dust reduction effect and ensures the cleanliness of the environment during the processing of ore raw materials.

[0010] In a preferred embodiment, internal pads are provided on both sides of the outer wall of the top of the cement platform, an inclined hole is provided inside the internal pad, an inlet is provided at one end of the inclined hole, the inlet is connected to the inlet hopper, and the end of the inclined hole away from the inlet is toward the feed hopper.

[0011] The sucked dust can be transferred through the suction pipe through the oblique port to the feed hopper of the gyratory crusher body to form a closed loop. Compared with the traditional collection method using dust bags, this solution is more suitable for large-scale ore crushing scenarios and reduces the dust collection pressure.

[0012] In a preferred embodiment, the spray dust suppression mechanism includes a connecting platform arranged on the outer wall of one side of the cement platform, a hydraulic pump is provided on the bottom outer wall of the connecting platform, a water diversion pipe is connected to the inlet of the hydraulic pump, and a water guide pipe is connected to the outlet of the hydraulic pump. A switching cylinder is installed at the central position of the top outer wall of the cover plate, and one end of the water guide pipe away from the hydraulic pump is connected to the top outer wall of the switching cylinder. The opposite ends of the two diversion pipes are respectively connected to the inner wall of the switching cylinder. A first atomizing nozzle is connected to the bottom outer wall of the switching cylinder through a bearing, the bottom of the first atomizing nozzle is a spherical structure, an internal impeller is installed on the inner wall of the first atomizing nozzle, and the first atomizing nozzle is located between the two dust hoods.

[0013] Through the set spray dust reduction mechanism, since the bottom of the first atomizing nozzle is a spherical structure, water mist can be sprayed radially from the central position below the cover plate, and when the dust suction mechanism sucks and gathers dust from both sides, the sprayed water mist can reduce the dust more specifically. At the same time, the connection position of the first atomizing nozzle and the adapter tube is set to a bearing connection. In this way, when the liquid flow impacts the internal impeller, the first atomizing nozzle not only sprays water mist, but also rotates at a certain speed, thereby changing the fixed spraying position of the first atomizing nozzle, so that the spraying range is wider.

[0014] In a preferred embodiment, the guiding and cleaning mechanism comprises an arc-shaped bar hole arranged on the top of the two inner pads, the inner walls of the two arc-shaped bar holes are provided with equidistantly distributed grille bars, the arc-shaped bar hole is connected to the inner wall of the inclined hole, and the arc-shaped bar hole is used in conjunction with the second atomizing nozzle arranged on the cover plate, and the bottom inner wall of the inclined hole near the end is provided with an isolation plug-in with equidistant distribution, the isolation plug-in is composed of two staggered filter plates, and a movable plug rod is inserted into the inner wall of the isolation plug-in, the top and bottom ends of the movable plug rod are respectively connected to the top inner wall and the bottom inner wall of the inclined hole, and a reset spring is provided on the top outer wall of the isolation plug-in, and an impact cone is provided on the bottom outer wall of the isolation plug-in, and a guide plate is installed on the inner wall of the inclined hole near the center position.

[0015] Through the set guiding and cleaning mechanism, a section of filtering and separation can be carried out at the position of the inclined hole near the feed hopper. When the air pump sucks the scattered dust into the inclined hole through the suction pipe, the airflow carrying the dust will pass through the set isolation plug-in. The filter plates staggered on the isolation plug-in will filter and block the dust, and the airflow will pass stably. The dust stuck on the filter plate can be cleaned by the water mist sprayed by the second atomizing nozzle above. The water mist enters the filter plate inside the inclined hole through the arc-shaped strip holes. At the same time, with the crushing vibration effect of the gyratory crusher body and the action of the reset spring, the isolation plug-in will be driven up and down inside the inclined hole, and the impact cone at the bottom of the isolation plug-in will knock on the bottom of the inclined hole in a linked manner, so as to assist in dredging the dust in the inclined mouth and prevent the dust from adhering to the filter plate after being damp.

[0016] A dust removal method for a dust removal device for crushing ore raw materials, comprising the following steps:

[0017] S1: First, stably install the cover plate on one side of the bottom of the cement platform, so that the first atomizing nozzle at the bottom of the cover plate is located directly above the feed hopper of the gyratory crusher body, and at the same time, the notch opened on one side of the cover plate faces the side of the concrete road surface connected to the cement platform;

[0018] S2: Next, the water diversion pipe connected to the inlet of the hydraulic pump is connected to the external water source, and the hydraulic pump is started, so that the external water source can normally supply water to the first atomizing nozzle and the second atomizing nozzle after being connected, and the hydraulic pump is adjusted at the same time, so that the liquid flow impacts the internal impeller to drive the first atomizing nozzle to rotate at a desired speed;

[0019] S3: Finally, use a transport vehicle to pull an appropriate amount of ore raw materials and pour them into the feed hopper from one side of the concrete road. The gyratory crusher body begins to coarsely crush the ore raw materials. At the same time, start the air pumps on both sides of the cement platform. Observe the dust suction of the dust hood after starting the air pump until no dust overflows from the annular atomization range formed by the second atomizing nozzle.
