Description

Technical Field

[0001] This invention relates to a dust removal device for exhaust gas from a cone crusher, belonging to the technical field of cone crusher. Background Technology

[0002] The cone crusher employs either dry oil or water sealing methods to prevent dust and impurities from entering the machine body, thus ensuring the cleanliness of the lubricating oil, extending the service life of the sliding bearings and thrust ball bearings, and ensuring reliable machine operation. The machine mainly consists of a frame, transmission, hollow eccentric shaft, cup-shaped bearing, crushing cone, adjusting device, adjusting sleeve, springs, and a hydraulic station for adjusting the discharge opening. During operation, the motor drives the eccentric sleeve to rotate via a horizontal shaft and a pair of bevel gears. The crushing cone's axis of rotation, propelled by the eccentric sleeve, oscillates, causing the crushing wall surface to alternately approach and move away from the jaw wall surface, thereby continuously compressing and bending the ore within the crushing chamber, thus crushing it.

[0003] Cone crushers are widely used in metallurgy, construction, road building, mining, and quarrying industries. They can crush various ores and rocks of medium to high hardness. The cone crusher uses grease seals, avoiding the problems of easy clogging in water supply and drainage systems and the tendency for water and oil to mix. The spring safety system is an overload protection device, allowing foreign objects and iron blocks to pass through the crushing chamber without damaging the crusher. This machine is available in standard and short-head types. Generally, the standard type has a larger feed size and a coarser discharge size, while the short-head type has a steeper crushing cone and a smaller feed size, which is beneficial for producing fine-grained materials. Therefore, the standard type is generally used for coarse and medium crushing, while the short-head type is used for medium and fine crushing.

[0004] Cone crushers are equipment used for crushing materials. During processing, dust is generated and spread. Therefore, it is necessary to collect the dust, treat the exhaust gas, and discharge it to ensure that the dust does not pollute the environment. Existing exhaust gas dust removal methods are relatively simple, and after a long period of dust removal, excessive dust adheres to the surface of the filter screen, which will affect the dust removal efficiency. Cleaning not only affects the dust removal operation, but frequent cleaning will also cause damage to the filter screen, affecting the service life of the cone crusher exhaust gas dust removal device.

[0013] In this technical solution, the air intake assembly includes an air intake hood, which is fixedly installed on the surface of the air outlet pipe. One side of the air intake hood is fixedly connected to the air intake pipe. The air intake pipe passes through the top of the housing and is connected to an air pump, which is fixedly installed on the top surface of the housing. Limiting rings are fixedly connected to the bottom inner wall of the air intake hood and the surface of the air outlet pipe. A sealing ring is provided between the limiting ring and the bottom of the air intake hood. The sealing ring is sleeved on the surface of the air outlet pipe and seals rotation within the air intake hood. The sealing ring is fixedly connected to a connecting pipe. The air intake hood consists of an outer hood and an annular plate. An annular gap for the rotation of the connecting pipe is formed between the hood and the annular plate. The connecting pipe is fixedly installed on the top of the horizontal guide hood. Vertically distributed nozzles are fixedly connected to the bottom of the sliding sleeve. The top of the nozzles is fixedly connected to one end of the connecting pipe. The nozzles are provided with multiple evenly distributed nozzles, each nozzle corresponding to the surface of the filter screen and corresponding to the vertical guide hood.

[0014] In this technical solution, a lug is fixedly installed on the outer wall of the sliding sleeve. The lug slides against the inner wall of the housing.

[0036] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0037] like Figures 1-10 As shown, the exhaust gas dust removal device applied to a cone crusher includes a device assembly 100. The device assembly 100 includes a housing 101 and a cyclone separator 103. The cyclone separator 103 is fixedly installed to the bottom of the housing 101 and is interconnected with it. A dust removal component 200 is fixedly installed inside the device assembly 100. An air intake component 300 is provided on the outside of the dust removal component 200. The air intake component 300 is rotatably connected to the inside of the housing 101. An adsorption component 400 is provided on one side of the device assembly 100. The adsorption component 400 is connected to the top of the housing 101 for guiding the exhaust gas generated by the cone crusher.

[0038] The dust removal assembly 200 includes a filter screen 201, which is fixedly installed inside the housing 101 via a flow equalization plate 213. The top of the filter screen 201 is fixedly connected to a track 202, and a sliding sleeve 203 is slidably connected to the surface of the track 202. A sealing plate 205 located inside the filter screen 201 is fixedly connected to the bottom of the sliding sleeve 203. The bottom edge and top of the sealing plate 205 are fixedly connected to a vertical flow guide hood 206 and a horizontal flow guide hood 207, respectively. The vertical flow guide hood 206 is in contact with the inner wall of the filter screen 201, and the vertical flow guide hood 206 communicates with the horizontal flow guide hood 207.

[0039] The housing 101 is circular and fixed by the support legs 102. A crossbar is provided on the support legs 102 and fixedly connected to the cyclone separator 103. The cyclone separator 103 is connected to the gas collection device of the cone crusher through the connecting pipe 104 to transfer the exhaust gas into the cyclone separator 103. The top of the cyclone separator 103 is fixedly connected to the housing 101 through the guide pipe 105. A flow equalization plate 213 is fixedly installed at the bottom of the housing 101. The guide pipe 105 is located below the flow equalization plate 213. The flow equalization plate 213 located inside the filter screen 201 is provided with fine holes to allow the exhaust gas to enter the filter screen 201 evenly.

[0040] In this technical solution, the connecting pipe 104 connected to the cone crusher transports the exhaust gas to the cyclone separator 103. The centrifugal force of the dust particles causes the large particles to gradually settle and be collected at the bottom of the cyclone separator 103. At this time, the exhaust gas carries fine dust from the guide pipe 105 into the interior of the shell 101, achieving a preliminary separation effect and ensuring the subsequent dust removal effect inside the shell 101.

[0041] The sliding sleeve 203 has a U-shaped cross-section and fits against the surface of the track 202. Multiple evenly distributed ball bearings 204 are embedded in the sliding sleeve 203 and contact the surface of the track 202. The two sides of the sliding sleeve 203 are angled to prevent dust accumulation. Two sliding sleeves 203 are symmetrically arranged on both sides of the sealing plate 205. The sealing plate 205 has a circular structure and fits inside the filter screen 201. Adhesive strips are provided on the edges of the sealing plate 205 to seal against the inner side of the filter screen 201. Each side of the sealing plate 205 has a connecting opening 208. 208 is connected to the top of the vertical guide shroud 206 and both ends of the horizontal guide shroud 207 respectively. The horizontal guide shroud 207 and the vertical guide shroud 206 have the same cross-sectional shape and are both U-shaped. The bottom of the horizontal guide shroud 207 and the vertical guide shroud 206 are fixedly connected to the rotating shaft 314 through the support rod 313. The bottom of the rotating shaft 314 is rotatably connected to the middle of the flow equalization plate 213, and the top of the rotating shaft 314 is fixedly connected to the sealing plate 205. The middle of the horizontal guide shroud 207 is fixedly connected to the end pipe 209, and the end pipe 209 is rotatably connected to the bottom of the air intake assembly 300.

[0042] In this technical solution, a sliding sleeve 203 is provided that can slide on the surface of the track 202. The ball bearing 204 ensures the stable rotation of the sliding sleeve 203 and the sealing plate 205. The sealing plate 205 has a circular structure and can rotate inside the filter screen 201 while ensuring that the airflow does not exit from the top of the filter screen 201. This allows the airflow to carry air through the mesh for dust filtration. When the sealing plate 205 rotates, it can drive the vertical guide hood 206 to always slide on the inner wall of the filter screen 201, ensuring that the airflow inside the vertical guide hood 206 is not disturbed by the flowing exhaust gas. This ensures that the locally blown air enters the vertical guide hood 206 and enters the horizontal guide hood 207 through the connecting port 208, thereby realizing that the airflow blown off the surface of the filter screen 201 is discharged separately and does not participate in the flow of exhaust gas, thus improving the cleaning effect.

[0043] An air outlet pipe 210 is fixedly installed in the middle of the housing 101. An end head 211 is fixedly connected to the bottom end of the air outlet pipe 210. An end tube 209 is rotatably connected to the surface of the end head 211. The end tube 209 and the surface of the end head 211 are sealed together so that the transverse guide shroud 207 rotates around the end head 211. The air outlet pipe 210 communicates with the interior of the purifier 212. The purifier 212 is fixedly installed to the top of the housing 101.

[0044] In this technical solution, the exhaust gas discharged from the transverse guide hood 207 is discharged from the end pipe 209 and discharged into the purifier 212 through the exhaust pipe 210. The purifier 212 captures and collects the blown-off dust, thereby blowing away the dust that clogs the mesh of the filter screen 201 and enabling real-time online cleaning.

[0045] The air intake assembly 300 includes an air intake shroud 301, which is fixedly installed on the surface of the air outlet pipe 210. One side of the air intake shroud 301 is fixedly connected to the air intake pipe 302. The air intake pipe 302 passes through the top of the housing 101 and is connected to the air pump 303, which is fixedly installed on the top surface of the housing 101. Limiting rings 304 are fixedly connected to the bottom inner wall of the air intake shroud 301 and the surface of the air outlet pipe 210. A sealing ring 305 is provided between the limiting ring 304 and the bottom of the air intake shroud 301. The sealing ring 305 is sleeved on the surface of the air outlet pipe 210. 1. The inner seal rotates, and the sealing ring 305 is fixedly connected to the connecting pipe 306. The air intake hood 301 consists of an outer cover and an annular plate. An annular gap is formed between the cover and the annular plate for the rotation of the connecting pipe 306. The connecting pipe 306 is fixedly installed on the top of the horizontal guide hood 207. The bottom of the sliding sleeve 203 is fixedly connected to a vertically distributed nozzle 307. The top of the nozzle 307 is fixedly connected to one end of the connecting pipe 306. The nozzle 307 is provided with multiple evenly distributed nozzles. Each nozzle is distributed correspondingly to the surface of the filter screen 201, and the nozzles are distributed correspondingly to the vertical guide hood 206.

[0046] In this technical solution, while treating the exhaust gas of the cone crusher, the air pump 303 is started to allow outside air to enter through the air inlet pipe 302. The airflow is then transported to the inside of the air inlet hood 301 and then to the nozzle 307 through the connecting pipe 306. The airflow ejected from the nozzle 307 backwashes the surface of the filter screen 201, and the dust blown off enters the vertical guide hood 206 and is discharged after passing through the horizontal guide hood 207 and the air outlet pipe 210.

[0047] The outer wall of the sliding sleeve 203 is fixedly installed with a lug 308, which slides against the inner wall of the housing 101. A support ring 309 is fixedly connected to the inner wall of the housing 101 and is located below the lug 308. The lug 308 is connected to one end of the connecting pipe 306, and the other end of the connecting pipe 306 is fixedly connected to the fixed gear 310. The fixed gear 310 is fixedly connected to the surface of the end tube 209. A drive motor 311 is fixedly installed at the top of the housing 101. The output end of the drive motor 311 is fixedly connected to the output gear 312, and the output gear 312 meshes with the fixed gear 310.

[0048] In this technical solution, when the drive motor 311 is started, the transmission of the output gear 312 and the fixed gear 310 drives the connecting pipe 306 and the end pipe 209 to rotate synchronously. When the end pipe 209 rotates around the end 211, the connecting pipe 306 drives the sealing ring 305 to rotate inside the air intake shroud 301. The design of the limiting ring 304 ensures that the sealing ring 305 always maintains a sealed state with the air intake shroud 301, so that the fixed gear 310, the connecting pipe 306, the sealing ring 305, the end pipe 209, the horizontal guide shroud 207 and the structure below it rotate synchronously. Without affecting the airflow, the vertical guide shroud 206 rotates evenly around the inner wall of the filter screen 201.

[0049] Furthermore, the lug 308 on the sliding sleeve 203 rotates on the support ring 309, which can ensure the stable rotation of the sliding sleeves 203 on both sides. After passing through the filter screen 201, the exhaust gas that enters between the filter screen 201 and the housing 101 is discharged upward from between the support ring 309 and the filter screen 201, and is transported to the adsorption assembly 400 from the fixed pipe 402.

[0050] The adsorption assembly 400 includes a housing 401, which is disposed on one side. The top of the housing 401 is fixedly connected to the top of the housing 401 via a fixing pipe 402. The fixing pipe 402 is fixedly connected to a transfer pump 403, which is also fixedly installed on the top of the housing 401. The bottom of the housing 401 is fixedly connected to an exhaust pipe 410 and a sewage discharge pipe 411, respectively. The exhaust pipe 410 is positioned above the sewage discharge pipe 411. A cavity for sewage storage is formed at the bottom of the housing 401. A lift pump 404 is fixedly installed on the outer wall of the housing 401 and is fixedly connected to an inlet pipe 405. The top end of the inlet pipe 405 is fixedly connected to the outlet pipe 406 of the U-shaped structure. The outlet pipe 406 is fixedly installed to the top of the box 401 and the outer walls on both sides. The outlet pipes 406 on both sides of the box 401 are connected to multiple branch pipes 407. Each branch pipe 407 is connected through the box 401. Several evenly distributed inclined plates 408 and guide plates 409 are fixedly connected inside the box 401. The inclined plates 408 are distributed correspondingly to the branch pipes 407. The guide plates 409 are correspondingly arranged below the inclined plates 408. Adjacent guide plates 409 are staggered on both sides of the box 401. The fixed pipe 402 is located at the top of the uppermost guide plate 409.

[0051] In this technical solution, the waste gas is further transported by the delivery pump 403, so that the waste gas in the shell 101 is transported to the box 401 through the fixed pipe 402. After the baffle plate 409 is set, the airflow is changed downward and transported, and finally discharged from the exhaust pipe 410. At the same time, the lift pump 404 works to draw the water stored at the bottom of the box 401 through the water inlet pipe 405 to the water outlet pipe 406, and flows out through the branch pipes 407 on both sides of the water outlet pipe 406. The water flow discharged from the branch pipes 407 is evenly distributed at the inclined plate 408, so that the water flow flows from the bottom of the inclined plate 408 and the box 401 to the baffle plate 409. When the evenly distributed water flows down from the baffle plate 409, it forms a water curtain and flows to the surface of the next baffle plate 409.

[0052] Specifically, when the exhaust gas is transported in the housing 401, the airflow will contact the surface of the guide plate 409 and cause dust to adhere. When the exhaust gas passes through the water curtain, dust and other impurities as well as odors are adsorbed by the water curtain. After multiple adsorption and purification processes, the exhaust gas is discharged from the exhaust pipe 410. After a long period of operation, the wastewater containing impurities is discharged through the drain pipe 411. The exhaust gas is discharged after passing through the cyclone separator 103, the filter screen 201, and the water curtain adsorption, which can effectively improve the dust removal effect.

The protection scope of this invention is defined by the appended claims.
