Description

Technical Field

[0001] The invention relates to the technical field of corundum block processing, in particular to a double-roller crusher used for corundum blocks. Background Art

[0002] Corundum is an aluminum oxide crystal with high hardness and high melting point. It is an extremely wear-resistant, heat-resistant and chemically stable material. Its hardness is second only to diamond in mineralogy. Therefore, corundum is often used as abrasive materials, wear-resistant parts, optical windows, high-temperature kiln tools and electronic devices.

[0003] When corundum is produced, it needs to be crushed using a crusher. There are many types of crushers on the market, including roller type, hammer type and blade type. Among them, the roller crusher, also known as the double roller crusher, is a device that uses two rollers rotating in opposite directions to crush materials. It is mainly composed of a motor, a bracket, a fixed roller, a movable roller and a safety spring. The working principle of the roller crusher is to use the friction between the material and the roller through the opposite rotation of two cylindrical rollers to roll the material into the crushing chamber formed by the two rollers, and achieve the crushing effect through crushing and grinding. The roller crusher has the advantages of simple structure and easy maintenance; continuous production and high efficiency; good crushing quality and uniform particles.

[0004] However, the existing double-roller crusher still has some shortcomings when in use. For example, the feed port of the double-roller crusher lacks a dust-proof mechanism, which causes the dust generated when the corundum block is crushed to easily spread outward through the feed port, thereby easily causing air pollution and damaging the working environment of the staff. If the staff works in this environment for a long time, it will also cause harm to the staff's health.

[0005] Therefore, it is urgent to redesign a new double-roll crusher for corundum blocks to solve the above problems. Summary of the invention

[0006] The present invention provides a double-roll crusher for corundum blocks to solve the technical problems raised in the above background technology.

[0007] The present invention provides a double-roller crusher for corundum blocks, the double-roller crusher for corundum blocks comprising a crusher body, a movable baffle mechanism and a dust suction component; The pulverizer body is connected with a feed port, a pair of side walls of the feed port are provided with dust suction ports, and a protective plate is provided on the upper side of the dust suction port; The movable baffle mechanism is installed in the feed port, and the movable baffle mechanism includes a V-shaped plate, the V-shaped plate is slidably connected to the side wall of the feed port, both ends of the V-shaped plate are hingedly connected to movable plates, the bottom of the V-shaped plate is fixedly connected to a base, and a pair of rebound mechanisms are connected between the movable plate and the base; The dust collecting assembly is installed on the side wall of the feed inlet and is arranged on the lower side of the V-shaped plate.

[0008] Optionally, the rebound mechanism includes a pair of connecting buckles, the connecting buckles are fixedly connected to the movable plate, and the connecting buckles are used to fix the moving rod; A moving rod is slidably connected between a pair of connecting buckles, and the moving rod is used to fix the connecting rod.

[0009] Optionally, a connecting rod is fixedly connected to the movable rod, and a pair of fixed sleeves are fixedly connected to a pair of side walls of the base, and the pair of fixed sleeves respectively correspond to a pair of connecting rods, and one end of the connecting rod passes through the fixed sleeve and is arranged in the base. When the movable plate is subjected to the force of the corundum block, the movable plate can be flipped under the action of the connecting buckle, the movable rod, the connecting rod and the fixed sleeve, so that the corundum block passes through the gap between the movable plate and the side wall of the feed port and enters the crusher body for crushing processing.

[0010] Optionally, one end of the connecting rod located inside the base is connected to a limiting plate, and the limiting plate is used to limit the connecting rod so that the connecting rod does not completely slide out of the base; A spring is provided on the outer side of the connecting rod, and the spring is provided between the moving rod and the base. When the movable plate is not subjected to the force of the corundum block, the movable plate returns to its original state under the action of the spring, so as to fold the feed port, reduce the opening area of ​​the feed port, and reduce the probability of dust generated during the processing of the corundum block overflowing through the feed port.

[0011] Optionally, the dust suction component includes a dust suction pump, the suction end of the dust suction pump is connected to a suction pipe, and the outlet end of the dust suction pump is connected to a first outlet pipe. When the dust suction pump is running, the dust suction pump sucks gas through the suction pipe and then discharges it through the first outlet pipe.

[0012] Optionally, a pair of side walls of the feed port are connected with fixed covers, the pair of fixed covers respectively cover a pair of dust suction ports, a second partition is provided inside the fixed cover, and the second partition divides the fixed cover into a filter chamber and an air outlet chamber.

[0013] Optionally, a pair of filter screens are installed in the filter cavity, and the filter screens are used to limit the impact ball particles and allow a number of impact ball particles to move irregularly between the pair of filter screens; A plurality of impact ball particles are arranged between the pair of filter screens. The gas sucked by the vacuum pump passes through the impact ball particles, so that the plurality of impact ball particles move irregularly between the pair of filter screens. The irregularly moving impact ball particles are used to impact the filter screen, so that the surface of the filter screen vibrates, thereby preventing the filter screen from being blocked by dust. At the same time, when the impact ball particles move irregularly, the outer membrane will be deformed by the impact, causing the pore size of the outer membrane surface to become larger. At this time, the gel liquid can be released through the capillaries and the elastic protective shell. The gel liquid can wrap the dust in the gas, thereby increasing the volume of the dust and allowing the dust to be better filtered by the filter.

[0014] Optionally, the impact ball particles include an outer membrane for temporarily storing gel liquid, and the outer membrane is provided with gel liquid. When the gel liquid is released, the gel liquid can wrap the dust to increase the volume of the dust so that the dust can be filtered by the filter net; The outer membrane surface is provided with a plurality of capillaries. When the impact ball particles collide with the filter screen, the pore size of the capillaries will become larger. At this time, the gel liquid can be released through the capillaries, otherwise the gel liquid will not be released; An elastic protective shell is arranged outside the outer membrane to protect the outer membrane and the gel liquid, and a plurality of holes are arranged on the elastic protective shell to release the gel liquid.

[0015] Optionally, the suction pipe is connected to the filter chamber, and the suction pipe is arranged on the upper side of the filter net, and the first air outlet pipe is connected to the air outlet chamber. When the dust suction pump is running, the dust suction pump can form a negative pressure state in the filter chamber through the suction pipe. Since the filter chamber is connected to the inside of the feed port through the dust suction port, when the dust suction pump is running, the gas in the feed port can be sucked to achieve the effect of sucking dust; The gas in the filter cavity is filtered by a pair of filter screens, sucked by the dust suction pump through the suction pipe, and then enters the gas outlet cavity through the first gas outlet pipe.

[0016] Optionally, a second gas outlet pipe is connected to the side wall of the feed port, and one end of the second gas outlet pipe located in the gas outlet cavity is connected to a second gas collecting hood, and the gas in the gas outlet cavity is discharged through the second gas collecting hood and the second gas outlet pipe; The fixed cover is connected with a discharge pipe, and the filter cavity is connected with the inside of the crusher body through the discharge pipe. A baffle is installed on the discharge pipe. When the baffle is opened, the dust or corundum block particles in the filter cavity will enter the crusher body through the discharge pipe to avoid the waste of corundum block particles.

[0017] The beneficial effects of the present invention are as follows: The double-roller crusher for corundum blocks can add a dust prevention mechanism at the feed port of the double-roller crusher through the setting of corresponding mechanisms, which can effectively prevent the dust generated when the corundum blocks are crushed from spreading to the outside, thereby preventing the dust from polluting the air environment, creating a good working environment for the staff, and greatly reducing the probability of the staff being affected by dust.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. It will be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] See also Figures 1 to 16 A double-roll crusher for corundum blocks of the present invention comprises a crusher body 1, a movable baffle mechanism 2 and a dust suction component.

[0024] The pulverizer body 1 is connected with a feed port 101 , and the corundum block enters the pulverizer body 1 through the feed port 101 , so that the pulverizer body 1 can be used to pulverize the corundum block.

[0025] In addition, a pair of side walls of the feed port 101 are both provided with dust suction ports 102. When the dust suction pump 3 is running, the dust suction pump 3 can form a negative pressure state in a pair of filter chambers through the suction pipe 301, and the filter chamber can then absorb the gas in the feed port 101 through the dust suction port 102, thereby absorbing the dust generated when the corundum block is crushed. This can not only prevent dust from overflowing through the gap between the movable plate 202 and the side wall of the feed port 101, and prevent dust from polluting the air environment, but also create a good working environment for the staff, greatly reducing the probability of the staff being affected by dust.

[0026] Specifically, a protective plate 103 is provided on the upper side of the dust suction port 102 , and the protective plate 103 is used to protect the dust suction port 102 and prevent the corundum block from hitting the dust suction port 102 , so as to ensure the safety of the dust suction port 102 .

[0027] In addition, a pair of protective covers 104 are installed on the inner wall of the feed port 101 . The pair of protective covers 104 respectively correspond to the pair of straight pipes 405 . The protective covers 104 are used to protect the straight pipes 405 .

[0028] See also Figures 1 to 16 The movable baffle mechanism 2 is installed in the feed port 101, and is used to reduce the opening area of ​​the feed port 101 to reduce the overflow of dust generated during the processing of the corundum block and reduce the probability of dust polluting the environment.

[0029] The movable baffle mechanism 2 includes a V-shaped plate 201, which is slidably connected to the side wall of the feed port 101. A pair of fixed blocks are provided on the inner wall of the feed port 101, and the base 203 is placed between the pair of fixed blocks. The movable baffle mechanism 2 can be taken out from the feed port 101 to maintain the reflux suction pump 209.

[0030] In addition, both ends of the V-shaped plate 201 are hingedly connected to a movable plate 202. The hinged connection between the movable plate 202 and the V-shaped plate 201 can not only ensure that the corundum block can enter the crusher body 1 normally without affecting the addition of the corundum block, but also reduce the opening area of ​​the feed port 101 and reduce the dust overflow generated during the processing of the corundum block.

[0031] Specifically, a base 203 is fixedly connected to the bottom of the V-shaped plate 201, and the base 203 is used to install the reflux suction pump 209 and the rebound mechanism.

[0032] See also Figures 1 to 16A pair of rebound mechanisms are connected between the movable plate 202 and the base 203, and the rebound mechanisms can be used to keep the V-shaped plate 201 and the movable plate 202 parallel in a natural state, that is, Figure 6 The state shown is to reduce the opening area of ​​the feed port 101. At the same time, the rebound mechanism can also be used to facilitate the addition of corundum blocks, so as to facilitate the crushing of the corundum blocks.

[0033] The rebound mechanism includes a pair of connecting buckles 204, which are fixedly connected to the movable plate 202 and used to fix the moving rod 205. The moving rod 205 is slidably connected between the pair of connecting buckles 204, and the moving rod 205 is used to fix the connecting rod 206. When the angle between the movable plate 202 and the V-shaped plate 201 changes, the moving rod 205 can slide between the pair of connecting buckles 204, so that the movable plate 202 can be folded, that is, Fig.11 The state shown makes it convenient to add corundum blocks into the crusher body 1.

[0034] In addition, the moving rod 205 is fixedly connected with a connecting rod 206, and the connecting rod 206 is used to connect the movable plate 202 and the base 203. A pair of side walls of the base 203 are fixedly connected with a pair of fixing sleeves 207, and the pair of fixing sleeves 207 correspond to the pair of connecting rods 206 respectively, and one end of the connecting rod 206 passes through the fixing sleeve 207 and is arranged in the base 203.

[0035] Adding a corundum block into the feed port 101 will generate a force on the movable plate 202. Under the force of the connecting buckle 204, the moving rod 205, the connecting rod 206 and the fixing sleeve 207, the movable plate 202 can be turned over, that is, it will become Fig.11 At this time, the corundum block can enter the pulverizer body 1 through the gap between the movable plate 202 and the side wall of the feed port 101 for pulverization.

[0036] Specifically, one end of the connecting rod 206 located in the base 203 is connected to a limiting plate, and the limiting plate is used to limit the connecting rod 206 to prevent the connecting rod 206 from completely sliding out of the base 203.

[0037] In addition, a spring 208 is provided on the outer side of the connecting rod 206, and the spring 208 is provided between the moving rod 205 and the base 203. When the movable plate 202 is not subjected to the force of the corundum block, the movable plate 202 returns to its original state under the force of the spring 208, that is, it becomes Figure 6 At this time, the movable baffle mechanism 2 can reduce the opening area of ​​the feed port 101, reduce the probability of dust generated during the processing of the corundum block overflowing through the feed port 101, and further reduce the pollution of the air environment caused by dust.

[0038] See also Figures 1 to 16A reflux air pump 209 is installed in the base 203. When the reflux air pump 209 is running, the reflux air pump 209 can absorb external gas through the connecting hole 211 and the through hole 213. A first partition 210 is provided on the upper side of the reflux air pump 209. The first partition 210 is used to protect the reflux air pump 209. The first partition 210 is provided with a plurality of connecting holes 211 to facilitate the reflux air pump 209 to absorb external gas.

[0039] A first air collecting hood 212 is installed at the air suction end of the reflux air suction pump 209 , and the first air collecting hood 212 covers the connecting hole 211 , so that the reflux air suction pump 209 can better absorb external air.

[0040] In addition, a plurality of through holes 213 are provided on the V-shaped plate 201, a return air box 214 is installed at the bottom of the base 203, and the gas outlet of the return air pump 209 is arranged in the return air box 214. The gas sucked by the return air pump 209 will enter the return air box 214.

[0041] Specifically, a pair of side walls of the return air box 214 are provided with a plurality of air outlet holes 215, and the air outlet holes 215 correspond to the dust suction port 102. The gas in the return air box 214 is then discharged to the dust suction port 102 through the plurality of air outlet holes 215, so that an air curtain can be formed on the lower side of the movable baffle mechanism 2, that is, Figure 6 The air curtain can further reduce the probability of dust spreading outward from the gap between the V-shaped plate 201 and the feed port 101, thereby preventing dust from polluting the environment.

[0042] See also Figures 1 to 16 The limit plate is connected with an elastic rope 216, one end of the elastic rope 216 passes through the first partition plate 210, and the end of the elastic rope 216 away from the connecting rod 206 is connected with a striking block 217, and the striking block 217 corresponds to the first partition plate 210. The elastic rope 216 is used to pull the striking block 217 to hammer the first partition plate 210 to prevent the connecting hole 211 on the first partition plate 210 from being blocked by dust.

[0043] Among them, an elastic sleeve 218 is provided on the outer side of the elastic rope 216, and the elastic sleeve 218 is provided between the impact block 217 and the first partition 210. The elastic sleeve 218 is used to support the impact block 217. When the movable plate 202 is folded under the action of the corundum block, the movable plate 202 will drive the connecting rod 206 to move, and one end of the connecting rod 206 is inserted into the base 203. At this time, the pulling force of the connecting rod 206 on the elastic rope 216 decreases, and the impact block 217 will be separated from the contact with the first partition 210 under the action of the elastic sleeve 218.

[0044] When the corundum block no longer exerts a force on the movable plate 202, the movable plate 202 will immediately return to its original state under the action of the spring 208. At this time, the movable plate 202 will pull the connecting rod 206 to move quickly, and the connecting rod 206 will pull the impact block 217 through the elastic rope 216, so that the impact block 217 can quickly hit the first partition 210, thereby causing the surface of the first partition 210 to vibrate, so that the connecting hole 211 will not be blocked by dust, thereby ensuring the suction effect of the reflux suction pump 209.

[0045] In addition, a pair of bottom plates 219 are installed in the base 203, and a fixed pulley 220 is installed on the bottom plate 219. The pair of fixed pulleys 220 correspond to a pair of elastic ropes 216 respectively. The fixed pulleys 220 are used to change the force direction of the elastic ropes 216 so that the connecting rod 206 can better pull the impact block 217 to impact the first partition 210.

[0046] See also Figures 1 to 16 Since there is a gap between the movable plate 202 and the side wall of the feed port 101, in order to prevent dust from spreading to the outside of the feed port 101 through the gap, the present application also provides a dust collection component on the side wall of the feed port 101. The dust collection component is installed on the side wall of the feed port 101 and is arranged on the lower side of the V-shaped plate 201.

[0047] The dust suction component includes a dust suction pump 3, the suction end of the dust suction pump 3 is connected to a suction pipe 301, the suction pipe 301 is connected to the filter cavity, and the suction pipe 301 is arranged on the upper side of the filter screen 401, that is, the two ends of the suction pipe 301 are respectively connected to a pair of filter cavities. The air outlet end of the dust suction pump 3 is connected to a first air outlet pipe 302, the first air outlet pipe 302 is connected to the air outlet cavity, that is, the two ends of the first air outlet pipe 302 are respectively connected to a pair of air outlet cavities.

[0048] When the dust suction pump 3 is running, the dust suction pump 3 can form a negative pressure state in the filter chamber through the suction pipe 301. Since the filter chamber is connected to the inside of the feed port 101 through the dust suction port 102, when the dust suction pump 3 is running, the gas in the feed port 101 can be sucked to absorb dust. The gas in the filter chamber is filtered by a pair of filter screens 401, sucked by the dust suction pump 3 through the suction pipe 301, and then enters the outlet chamber through the first outlet pipe 302.

[0049] See also Figures 1 to 16 A pair of side walls of the feed port 101 are connected to fixed covers 4, and the pair of fixed covers 4 respectively cover a pair of dust suction ports 102, that is, Figure 6 In the state shown, the fixed cover 4 is used to guide the flow of the gas sucked by the dust suction pump 3 .

[0050] A second partition plate 410 is provided in the fixed cover 4, and the second partition plate 410 divides the fixed cover 4 into a filter cavity and an air outlet cavity.

[0051] In addition, a pair of filter screens 401 are installed in the filter chamber, and the filter screens 401 are used to filter the gas sucked by the dust suction pump 3 and filter the dust in the gas. At the same time, the filter screens 401 are used to limit the impact ball particles 402, so that a plurality of impact ball particles 402 can move irregularly between the pair of filter screens 401.

[0052] Specifically, a plurality of impact ball particles 402 are arranged between a pair of filter screens 401. The gas sucked by the dust suction pump 3 will pass through the pair of filter screens 401 and the impact ball particles 402. Under the action of the high-pressure gas, the impact ball particles 402 will move irregularly between the pair of filter screens 401. The irregularly moving impact ball particles 402 will hit the pair of filter screens 401, thereby causing the surface of the filter screen 401 to vibrate, and the filter screen 401 can be prevented from being blocked by dust by the vibration.

[0053] When the impact ball particles 402 move irregularly, the outer film 4021 is deformed by the impact, so that the pores on the surface of the outer film 4021 become larger, and at this time, the gel liquid 4022 can be released through the pores and the elastic protective shell 4023. Under the action of the high-pressure gas, the gel liquid 4022 is blown into a number of tiny droplets, and the tiny droplets of gel liquid 4022 can wrap the dust in the gas, thereby increasing the volume of the dust, so that the dust can be better filtered by the filter 401, greatly improving the dust filtering effect.

[0054] See also Fig.10 The impact ball particle 402 includes an outer film 4021 for temporarily storing the gel liquid 4022. The outer film 4021 is provided with the gel liquid 4022. When the gel liquid 4022 is released, the gel liquid 4022 is blown into a plurality of tiny droplets by the high-pressure gas. The tiny droplets of the gel liquid 4022 can wrap the dust to increase the volume of the dust so that the dust can be filtered by the filter 401.

[0055] There are a number of capillaries on the surface of the outer film 4021. When the impact ball particles 402 collide with the filter 401, the aperture of the capillaries will become larger. At this time, the gel liquid 4022 can be released through the capillaries, otherwise the gel liquid 4022 will not be released.

[0056] In addition, an elastic protective shell 4023 is provided outside the outer film 4021 to protect the outer film 4021 and the gel liquid 4022 . Meanwhile, when the high-pressure gas passes through the impact ball particles 402 , the impact ball particles 402 can collide with a pair of filter screens 401 .

[0057] Specifically, a plurality of holes 4024 are provided on the elastic protective shell 4023 to release the gel liquid 4022 .

[0058] See also Figures 1 to 16A second gas outlet pipe 403 is connected to the side wall of the feed port 101 , and one end of the second gas outlet pipe 403 located in the gas outlet cavity is connected to a second gas collecting hood 404 , and the gas in the gas outlet cavity is discharged through the second gas collecting hood 404 and the second gas outlet pipe 403 .

[0059] One end of the second gas outlet pipe 403 located in the feed port 101 is connected to a straight pipe 405, on which a plurality of gas outlet heads 406 are installed, and the gas outlet heads 406 correspond to the through holes 213. The gas in the gas outlet cavity enters the straight pipe 405 through the second gas collecting hood 404 and the second gas outlet pipe 403, and then is blown toward the through holes 213 through the plurality of gas outlet heads 406.

[0060] When the reflux suction pump 209 is running, the reflux suction pump 209 can absorb the gas, so that an air curtain can be formed on both the upper and lower sides of the V-shaped plate 201. Figure 6 The double-layer air curtain can prevent dust from overflowing through the feed port 101, prevent dust from polluting the environment, create a good working environment for the staff, and greatly reduce the probability of the staff being affected by dust.

[0061] Preferably, the inclination angle of the gas outlet head 406 can be adjusted. When the reflux suction pump 209 is running, the gas outlet head 406 faces the through hole 213, and the reflux suction pump 209 can absorb the gas ejected by the gas outlet head 406 through the through hole 213 to form an air curtain on the upper side of the V-shaped plate 201. When the reflux suction pump 209 is not running, the gas outlet head 406 can be rotated toward the port of the feed inlet 101, so that the gas discharged from the gas outlet head 406 is discharged through the port of the feed inlet 101.

[0062] In addition, a discharge pipe 407 is connected to the fixed cover 4, and the filter cavity is connected to the inside of the pulverizer body 1 through the discharge pipe 407. A baffle 408 is installed on the discharge pipe 407. When the baffle 408 is opened, the dust or corundum block particles in the filter cavity will enter the pulverizer body 1 through the discharge pipe 407 to avoid the waste of corundum block particles.

[0063] Specifically, the side wall of the fixed cover 4 is connected with a switch door 409, and the switch door 409 corresponds to a pair of filter screens 401 and impact ball particles 402. When the switch door 409 is opened, the filter screen 401 can be cleaned, and the impact ball particles 402 can also be replenished.

[0064] When used, a corundum block is put into the feed port 101. When the corundum block falls, it exerts a squeezing force on the movable plate 202. Under the action of the connecting buckle 204, the moving rod 205, the connecting rod 206 and the fixing sleeve 207, the movable plate 202 can be turned over, that is, it becomes Fig.11At this time, the corundum block can enter the pulverizer body 1 through the gap between the movable plate 202 and the side wall of the feed port 101 for pulverization.

[0065] During the crushing of the corundum block, the opening area of ​​the feed port 101 can be reduced by the action of the movable baffle mechanism 2, thereby reducing the spillage of dust generated during the crushing of the corundum block and preventing dust from polluting the environment.

[0066] In order to prevent dust from spreading out of the feed port 101 through the gap between the V-shaped plate 201 and the feed port 101, the dust suction pump 3 can be operated, and the dust suction pump 3 can respectively absorb the gas in a pair of filter chambers through the suction pipe 301, so that the filter chamber forms a negative pressure state. Since the filter chamber is connected to the inside of the feed port 101 through the dust suction port 102, the gas in the feed port 101 will enter the filter chamber through the dust suction port 102, that is, it can absorb the dust generated when the corundum block is crushed, so that the dust will not spread outward.

[0067] The gas in the filter cavity will be filtered through a pair of filter screens 401. When the gas passes through the impact ball particles 402, the impact ball particles 402 will move irregularly between the pair of filter screens 401. The irregularly moving impact ball particles 402 will hit the pair of filter screens 401, thereby causing the surface of the filter screen 401 to vibrate, and the vibration can prevent the filter screen 401 from being blocked by dust.

[0068] At the same time, when the impact ball particles 402 move irregularly, the outer film 4021 is deformed by the impact, so that the pores on the surface of the outer film 4021 become larger, and at this time, the gel liquid 4022 can be released through the pores and the elastic protective shell 4023. Under the action of the high-pressure gas, the gel liquid 4022 is blown into a number of tiny droplets, and the tiny droplets of gel liquid 4022 can wrap the dust in the gas, thereby increasing the volume of the dust, so that the dust can be better filtered by the filter 401, greatly improving the dust filtering effect.

[0069] The filtered gas then enters into a pair of gas outlet cavities through the first gas outlet pipe 302. The gas in the gas outlet cavity then enters into the straight pipe 405 through the second gas collecting cover 404 and the second gas outlet pipe 403, and is discharged through a plurality of gas outlet heads 406.

[0070] If the staff observes that the dust concentration generated by the corundum block is relatively high, the reflux suction pump 209 can be operated, and the air outlet head 406 can be rotated toward the through hole 213. When the reflux suction pump 209 is running, the reflux suction pump 209 forms a negative pressure at the through hole 213 through the connecting hole 211, and the gas ejected by the air outlet head 406 can be absorbed. The gas enters the base 203 through the through hole 213, and enters the return air box 214 through the air outlet end of the reflux suction pump 209, and finally is blown toward the dust suction port 102 through a plurality of air outlet holes 215. By repeating this cycle, a double-layer air curtain can be formed on the upper and lower sides of the V-shaped plate 201, that is, Figure 6 Status shown.

[0071] The double-layer air curtain can effectively prevent dust from spilling out through the feed port 101, thereby preventing dust from polluting the environment, creating a good working environment for the staff, and greatly reducing the probability of the staff being affected by dust. At the same time, when the corundum blocks are added, they will pass through the double-layer air curtain in turn without causing dust to spill out.

[0072] In addition, by setting up a double-layer air curtain, the utilization rate of the tiny droplets of gel liquid 4022 in the gas can be improved, so that the tiny droplets of gel liquid 4022 can wrap the dust in the gas so that the dust can be better filtered.

[0073] In addition, during the process of adding the corundum blocks, the impact block 217 will reciprocately impact the first partition plate 210 to prevent the connecting hole 211 from being blocked, thereby ensuring the suction effect of the reflux suction pump 209.

[0074] If the staff observes that the dust concentration generated by the corundum block is small, they can just run the dust suction pump 3 to absorb the dust, without running the reflux suction pump 209, thereby reducing the overall energy consumption.

[0075] During the processing of the corundum blocks, the baffle 408 can be opened to allow the corundum block particles filtered by the filter screen 401 to enter the pulverizer body 1 through the discharge pipe 407, thereby avoiding the waste of the corundum block particles.
