Description

Technical Field

[0001] This invention relates to the field of cement silo technology, specifically to a cement silo that is easy to clean and maintain. Background Technology

[0002] Water-stabilized crushed stone, also known as cement-stabilized crushed stone, is a common road base material. It is made by mixing crushed stone of a certain gradation with sufficient cement and water. After compaction and curing, when its strength meets the specified requirements, it is called cement-stabilized crushed stone. In the production process of water-stabilized crushed stone, cement silos are large containers used to store cement. Through four core functions—efficient storage, stable material supply, safety and environmental protection, and intelligent management—cement silos have become an indispensable infrastructure for modern concrete production. When storing powder, the powder enters the silo via pneumatic or mechanical conveying. The air inside the silo is discharged through a dust collector filter, and the dust is trapped. When discharging the powder, it flows out from the bottom of the cone under gravity and is transported to downstream equipment via a screw conveyor or air chute. During the process of discharging powder from a cement silo, if the powder has high moisture content, it may cause bridging or clumping at the bottom of the silo, making it impossible to discharge and requiring maintenance of the cement silo. At the same time, when water droplets flow along the inner wall of the silo, they come into contact with the powder at the silo wall, causing the powder to adhere to the silo wall, increasing the difficulty of cleaning and maintenance. The scraper that rotates along a fixed path cannot be adjusted when scraping the powder, resulting in unsatisfactory scraping effect. Summary of the Invention

[0003] To achieve the above objectives, the present invention provides the following technical solution: A cement silo that is easy to clean and maintain includes: The silo is composed of a cylindrical tube and a conical tube at the bottom of the cylindrical tube, and a feed pipe is installed on the top of the outer side of the silo. A ladder is fixedly installed on the outer side of the silo. A dust removal mechanism is installed on the top of the silo, and a first motor is fixedly installed on the top of the dust removal mechanism. The output end of the first motor passes through the dust removal mechanism and extends into the interior of the silo. A material guiding mechanism is installed at the bottom end of the silo and is used to guide the powder inside the silo outward. A connecting ring and an inner support ring are fixedly installed on the inner wall of the cone. The connecting ring is located above the inner support ring. A cylinder is fixedly installed at the bottom of the inner support ring. The output end of the cylinder passes through the inner support ring and extends to the top. A fixing plate is fixedly installed at the output end of the cylinder. An outer support rod is fixedly installed on the inner wall of the connecting ring. The end of the outer support rod away from the connecting ring is inclined downwards, and the outer support rod is evenly installed along the center position of the connecting ring. An inner support rod is fixedly installed on the outer side of the fixing plate. Through the cooperation between the outer support rod and the inner support rod, the outer support... The staggered and inclined cooperation between the rod and the inner support rod, during the reciprocating motion, causes the bridging or clumping powder between the outer support rod and the inner support rod to be squeezed and sheared, dispersing the bridging or clumping powder and smoothly discharging it from the bottom discharge position. At the same time, by using the rod to contact the material, compared with using air jets or propeller blades to drive the powder, the rod ensures the smooth discharge of the powder during the working process, while reducing the difficulty of cleaning when the powder adheres, making cleaning and maintenance easier. The end of the inner support rod away from the fixed plate is inclined downward, and the inner support rod is located between the outer support rods. The output end of the first motor is fixedly connected to a rotating shaft via a coupling. Two sliding rings are fixedly installed on the outer side of the rotating shaft, and each sliding ring has a groove on its opposite surface. Through the cooperation of the inner sliding plate and the scraper plate, during rotation, the powder on the inner side of the scraper plate is pushed by the powder on the inner side as the scraper plate rotates. Compared to a fixed rotating scraper plate, the sliding connection between the inner sliding plate and the sliding rings allows the scraper plate to be squeezed tightly against the inner wall of the silo during rotation, reducing the gap between the silo and the scraper plate and improving the scraping effect on the powder adhering to the silo wall. The two ends of the inner sliding plate are slidably installed between the sliding rings and are adapted to slide within the grooves of the sliding rings. A scraper plate is fixedly installed on the outer side of the inner sliding plate, with its opposite surface being an inclined plane. A material-pulling rod is fixedly installed at the bottom of the lower sliding ring.

[0004] Preferably, an air pipe is fixedly installed at the air inlet end of the cylinder, and the end of the air pipe away from the cylinder passes through the silo and extends to its outer side. A baffle is fixedly installed at the bottom of the outer side of the silo to protect the outlet of the silo. In rainy or snowy weather, rainwater cannot come into contact with the connection between the outlet of the silo and the material guiding mechanism, thus preventing the powder at the connection from agglomerating after contact with rainwater, which would cause powder blockage. The end of the baffle away from the silo is inclined downward.

[0005] Preferably, the dust removal mechanism includes an inner clamping cylinder, which is fixedly installed on the top of the silo, and a baffle is fixedly installed at the bottom of the inner clamping cylinder. The baffle is a conical cover with an outer diameter that gradually decreases from top to bottom. The baffle blocks the powder, preventing it from directly impacting the filter bag during introduction. This avoids a large amount of powder directly contacting the filter bag surface, which would cause a large amount of dust to adhere to the filter bag surface, preventing the filter bag from filtering and affecting the dust removal effect. At the same time, when the internal humidity is high and water droplets condense at the top, the baffle guides the downward-flowing water droplets towards the center, reducing the number of water droplets flowing along the silo wall and preventing water droplets from contacting the silo wall. After the powder is applied, it adheres to the cylinder wall, increasing the difficulty of cleaning and maintenance. A groove cover is fixedly installed at the bottom of the inner cylinder. The groove cover is located inside the baffle cover. The bottom of the groove cover is an arc surface that bulges downward at the center position, and the bottom of the groove cover has evenly spaced slots. A filter bag is fixedly installed at the bottom of the groove cover. An inner gasket ring is fixedly installed on the inner wall of the inner cylinder. The end of the inner gasket ring away from the inner cylinder is inclined upward. An outer groove cylinder and an inner groove cylinder are fixedly installed at the top of the inner gasket ring. The tops of the inner groove cylinder and the outer groove cylinder are flush, and there is a gap between the inner groove cylinder and the outer groove cylinder. A sponge cylinder is fixedly installed between the inner groove cylinder and the outer groove cylinder.

[0006] Preferably, the bottom of the outer groove cylinder is provided with an air groove, the top of the outer groove cylinder is provided with guide grooves evenly distributed, and the tops of the inner and outer groove cylinders are fixedly installed with top covers. The edges of the top covers are inclined downwards, and an outer retaining ring is fixedly installed at the bottom edge of the top cover. The top of the inner clamping cylinder is fixedly installed with an inclined ring plate and a support ring. Through the cooperation of the inner and outer groove cylinders, when external air enters the silo, it is first guided into the sponge cylinder through the air groove at the bottom of the outer groove cylinder. With the help of the guide groove at the top of the outer groove cylinder, the air passes through the sponge cylinder from bottom to top and is finally guided into the silo through the guide groove, so that the air fully contacts the sponge cylinder. The water absorption of the sponge cylinder is used to prevent the outside air from bringing in a large amount of moisture, which would cause the powder to clump. The tops of the support ring and the inclined ring plate are in contact with the bottom of the top cover, and the tops of the support ring and the inclined ring plate are both provided with notches. The top of the inclined ring plate is inclined inwards.

[0007] Preferably, the material guiding mechanism includes an arc cover, the top of which is fixedly connected to the bottom of the hopper, and a connecting pipe is fixedly installed at the bottom of the arc cover. A material guiding pipe is fixedly installed at the bottom of the connecting pipe, and the material guiding pipe is inclined at the bottom of the connecting pipe. A second motor is fixedly installed at one end of the material guiding pipe. The inner wall of the arc cover is arc-shaped and the inner diameter gradually decreases from top to bottom. Through the cooperation of the arc cover and the connecting pipe, during the process of introducing powder into the material guiding pipe, the arc cover provides a certain buffer storage space for powder that cannot enter the material guiding pipe in time, avoiding a large amount of powder being directly introduced into the material guiding pipe, which would prevent the auger blades from discharging the powder in time and causing blockage in the material guiding pipe. The output end of the second motor passes through the material guiding pipe and extends into its interior, and a drive shaft is fixedly installed at the output end of the second motor. An auger blade is fixedly installed on the outer side of the drive shaft.

[0008] This invention provides a cement silo that is easy to clean and maintain. It has the following beneficial effects: 1. This easy-to-clean and maintain cement silo utilizes an inner sliding plate and a scraper blade. During rotation, the inner powder material is pressed against the inclined surface of the scraper blade, creating contact pressure. This pushes the powder material against the inner wall of the silo as the scraper blade rotates. Compared to a fixed rotating scraper blade, the sliding connection between the inner sliding plate and the sliding groove ring allows the scraper blade to be pressed tightly against the inner wall of the silo during rotation, reducing the gap between the silo and the scraper blade and improving the scraping effect on the powder adhering to the silo wall.

[0009] Second, this easy-to-clean and maintain cement silo, through the cooperation between the outer and inner support rods, allows for staggered and inclined cooperation between the outer and inner support rods. During the reciprocating motion, the bridging or clumping powder between the outer and inner support rods is squeezed and sheared, dispersing the bridging or clumping powder and allowing it to be smoothly discharged from the bottom outlet. At the same time, by utilizing the contact between the rods and the material, compared to using air jets or propeller blades to drive the powder, the rods ensure smooth discharge of the powder during operation while reducing the difficulty of cleaning when powder adheres, thus facilitating cleaning and maintenance.

[0010] Third, this easy-to-clean and maintain cement silo protects the outlet of the silo with a baffle. In rainy or snowy weather, rainwater cannot come into contact with the connection between the outlet of the silo and the material guiding mechanism, thus preventing the powder at the connection point from clumping after contact with rainwater and causing powder blockage.

[0011] Fourth, this easy-to-clean and maintain cement silo uses a baffle to block the powder, preventing it from directly impacting the filter bags during introduction. This avoids a large amount of powder directly contacting the filter bag surface, which would cause a large amount of dust to adhere to the filter bag surface, preventing the filter bags from filtering and affecting the dust removal effect. At the same time, when the internal humidity is high and water droplets condense at the top, the baffle guides the downward-flowing water droplets towards the center, reducing the number of water droplets flowing along the silo wall. This prevents water droplets from contacting the powder on the cylinder wall and causing the powder to adhere to the cylinder wall, increasing the difficulty of cleaning and maintenance.

[0012] 5. This easy-to-clean and maintain cement silo, through the cooperation of the inner and outer troughs, allows external air to enter the silo first through the air groove at the bottom of the outer trough and then through the guide groove at the top of the outer trough, so that the air passes through the sponge from bottom to top and is finally guided into the silo through the guide groove. This ensures that the air fully contacts the sponge and utilizes the water absorption of the sponge to prevent the introduction of a large amount of moisture when the outside air enters, which would cause the powder to clump.

[0013] VI. This easy-to-clean and maintain cement silo, through the cooperation of the arc cover and the connecting pipe, provides a certain buffer storage space for powder that cannot enter the feed pipe in time during the process of introducing powder into the feed pipe. This avoids a large amount of powder being directly introduced into the feed pipe, which would prevent the auger blades from being able to discharge the powder in time and cause blockage in the feed pipe.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] First embodiment, such as Figures 1 to 6 As shown, the present invention provides a technical solution: A cement silo that is easy to clean and maintain includes: The silo 1 is composed of a cylindrical cylinder and a conical cylinder at the bottom of the cylindrical cylinder. A feed pipe 5 is installed on the top of the outer side of the silo 1, and a ladder 6 is fixedly installed on the outer side of the silo 1. Dust removal mechanism 2 is installed on the top of the silo 1, and a first motor 4 is fixedly installed on the top of the dust removal mechanism 2. The output end of the first motor 4 passes through the dust removal mechanism 2 and extends into the interior of the silo 1. The material guiding mechanism 3 is installed at the bottom end of the silo 1 and is used to guide the powder inside the silo 1 outward. A connecting ring 7 and an inner support ring 13 are fixedly installed on the inner wall of the cone. The connecting ring 7 is located above the inner support ring 13. A cylinder 14 is fixedly installed at the bottom of the inner support ring 13. The output end of the cylinder 14 passes through the inner support ring 13 and extends to the top. A fixed plate 10 is fixedly installed at the output end of the cylinder 14. An outer support rod 11 is fixedly installed on the inner wall of the connecting ring 7. By connecting the gas pipeline to the gas pipe 9, high-pressure gas enters the cylinder 14 through the gas pipe 9, driving the cylinder 14 to reciprocate up and down at its output end. During the reciprocating motion, the fixed plate 10 drives the inner support rod 12 to reciprocate up and down between the outer support rods 11. The outer support rod 11 is inclined downward at the end away from the connecting ring 7, and the outer support rod 11 is evenly installed along the center position of the connecting ring 7. The inner support rod 12 is fixedly installed on the outer side of the fixed plate 10. During the reciprocating motion, the interlacing between the inner support rod 12 and the outer support rod 11, combined with the inclined setting of the inner support rod 12 and the outer support rod 11, drives the powder at the discharge position of the silo 1. During the interlacing reciprocating motion, it comes into contact with the bridged or agglomerated powder, applies pressure to the bridged or agglomerated powder, and makes the powder smoothly discharged from the discharge port at the bottom. The inner support rod 12 is inclined downward at the end away from the fixed plate 10, and the inner support rod 12 is located between the outer support rods 11. The output end of the first motor 4 is fixedly connected to a rotating shaft 15 via a coupling. Two sliding rings 16 are fixedly installed on the outer side of the rotating shaft 15. The first motor 4 drives the sliding rings 16 to rotate inside the bin 1 via the rotating shaft 15. During rotation, the sliding rings 16 drive the scraper blade 17 to rotate on the bin wall via the inner sliding plate 18. Sliding grooves are formed on opposite surfaces of the sliding rings 16. The two ends of the inner sliding plate 18 are slidably fitted between the sliding rings 16, and are adapted to slide within the grooves of the sliding rings 16. A scraper plate 17 is fixedly installed on the outer side of 8. During rotation, the powder inside the scraper plate 17 is squeezed by the inclined surface of the scraper plate 17. During rotation, the pressure is transmitted to the inner slide plate 18, which slides between the slide rings 16. The scraper plate 17 is pressed tightly against the inner wall of the bin 1 by the powder, and the powder is scraped. The opposite surface of the scraper plate 17 is inclined. A material feeding rod 19 is fixedly installed at the bottom of the slide ring 16 below.

[0018] An air pipe 9 is fixedly installed at the air inlet end of the cylinder 14. The end of the air pipe 9 away from the cylinder 14 passes through the chamber 1 and extends to its outer side. A baffle 8 is fixedly installed at the bottom of the outer side of the chamber 1. The end of the baffle 8 away from the chamber 1 is inclined downward.

[0019] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 7 to 10As shown, the dust removal mechanism 2 includes an inner clamping cylinder 202, which is fixedly installed on the top of the silo 1. A baffle 203 is fixedly installed at the bottom of the inner clamping cylinder 202. The baffle 203 is a conical cover with an outer diameter that gradually decreases from top to bottom. A grooved cover 209 is fixedly installed at the bottom of the inner clamping cylinder 202, located inside the baffle 203. The bottom of the grooved cover 209 is an arc surface that bulges downwards from the center. When introducing powder, the baffle 203 blocks the powder, preventing it from directly contacting the filter bag 208 after entering the silo 1 under the pneumatic conveying equipment. Simultaneously, the powder accumulates from the bottom of the silo 1 due to its own weight and the guiding effect of the baffle 203. When discharging powder, the powder is discharged from the bottom outlet in cooperation with the guiding mechanism 3, thus discharging the powder from the silo 1. During the powder introduction and discharge process, the powder inside the silo 1... Powder splashes, and excess gas passes through the filter bag 208 and enters the top of the tank cover 209. The filter bag 208 filters out the powder. Then, the air passes sequentially through the inner tank cylinder 211, the sponge cylinder 212, the outer tank cylinder 210, the support ring 206, and the inclined ring plate 205, and is discharged through the gap between the top cover 201 and the inner clamping cylinder 202. The bottom of the tank cover 209 has evenly spaced slots. The filter bag 208 is fixedly installed at the bottom of the tank cover 209. The inner wall of the inner clamping cylinder 202 is fixedly installed with an inner gasket ring 207. The end of the inner gasket ring 207 away from the inner clamping cylinder 202 is inclined upward. The top of the inner gasket ring 207 is fixedly installed with the outer tank cylinder 210 and the inner tank cylinder 211. The tops of the inner tank cylinder 211 and the outer tank cylinder 210 are flush, and there is a gap between the inner tank cylinder 211 and the outer tank cylinder 210. The sponge cylinder 212 is fixedly installed between the inner tank cylinder 211 and the outer tank cylinder 210.

[0020] An air groove is provided at the bottom of the outer side of the outer groove cylinder 210, and guide grooves are evenly provided at the top of the outer side of the inner groove cylinder 211. A top cover 201 is fixedly installed on the top of the inner groove cylinder 211 and the outer groove cylinder 210. The edge of the top cover 201 is inclined downward, and an outer retaining ring 204 is fixedly installed at the bottom edge of the top cover 201. An inclined ring plate 205 and a support ring 206 are fixedly installed on the top of the inner clamping cylinder 202. When external air enters the interior, the air passes through the notch of the inclined ring plate 205 and the support ring 206, and is guided into the contact sponge cylinder 212 through the air groove at the bottom of the outer side of the outer groove cylinder 210, and is guided into the interior of the hopper cylinder 1 through the guide groove at the top of the outer side of the inner groove cylinder 211. The top of the support ring 206 and the inclined ring plate 205 are in contact with the bottom of the top cover 201, and the top of the support ring 206 and the inclined ring plate 205 are both provided with notches. The top of the inclined ring plate 205 is inclined inward.

[0021] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 11 to 12As shown, the material guiding mechanism 3 includes an arc cover 31, the top of which is fixedly connected to the bottom of the silo 1. A connecting pipe 32 is fixedly installed at the bottom of the arc cover 31, and a material guiding pipe 34 is fixedly installed at the bottom of the connecting pipe 32. The material guiding pipe 34 is inclined at the bottom of the connecting pipe 32. The second motor 33 drives the transmission shaft 35 to rotate, causing the transmission shaft 35 to drive the auger blade 36 to rotate inside the material guiding pipe 34. Through the connection between the arc cover 31 and the connecting pipe 32, the powder in the silo 1 is guided into the material guiding pipe 34 under its own gravity. Then, through rotation... The auger blade 36 guides the powder out from one end of the guide pipe 34. A second motor 33 is fixedly installed at one end of the guide pipe 34. The inner wall of the arc cover 31 is arc-shaped and the inner diameter gradually decreases from top to bottom. The output end of the second motor 33 passes through the guide pipe 34 and extends into its interior. During the powder transmission process, the arc shape of the inner wall of the arc cover 31 provides a buffer space for the powder to stay when the guide pipe 34 cannot discharge the powder in time. The output end of the second motor 33 is fixedly installed with a drive shaft 35, and the auger blade 36 is fixedly installed on the outside of the drive shaft 35.

[0022] In use, the cement powder to be stored is introduced into the silo 1 through the feed pipe 5 by the pneumatic conveying equipment. The silo 1 provides storage space for the cement powder. When the cement powder is needed, the cement powder inside the silo 1 is exported through the material guiding mechanism 3 at the bottom of the silo 1. During the process of powder being introduced into and exported from the silo 1, the dust removal mechanism 2 filters out the powder in the silo 1 to prevent the powder from splashing and spreading and causing dust pollution.

[0023] During the process of discharging cement powder, the gas pipeline is connected to the gas pipe 9, allowing high-pressure gas to enter the cylinder 14 through the gas pipe 9, driving the cylinder 14 to reciprocate up and down at its output end. During this reciprocating motion, the fixed plate 10 drives the inner support rod 12 to reciprocate up and down between the outer support rod 11. During this reciprocating motion, the interlacing of the inner support rod 12 and the outer support rod 11, along with their inclined arrangement, drives the powder at the discharge position of the silo 1. During this interlacing reciprocating motion, the powder comes into contact with the bridging or agglomerated powder, applying pressure to the bridging or agglomerated powder, allowing the powder to be smoothly discharged from the bottom discharge port.

[0024] When the inner support rod 12 and the outer support rod 11 crush the powder that has clumped at the outlet, the first motor 4 drives the sliding ring 16 to rotate inside the bin 1 via the rotating shaft 15. During the rotation of the sliding ring 16, the inner slide plate 18 drives the scraper 17 to rotate on the wall of the bin 1. During the rotation, the powder inside the scraper 17 is squeezed by the inclined surface of the scraper 17. The pressure is transmitted to the inner slide plate 18 during the rotation, causing the inner slide plate 18 to slide between the sliding ring 16. Under the pressure of the powder, the scraper 17 is pressed tightly against the inner wall of the bin 1, scraping the adhered powder.

[0025] In the dust removal mechanism 2, when the powder is introduced, the baffle 203 prevents the powder from directly contacting the filter bag 208 after entering the silo 1 driven by the pneumatic conveying equipment. Simultaneously, the powder's own weight and the guiding force of the baffle 203 cause the powder to accumulate from the bottom of the silo 1. When the powder is discharged, it is discharged from the bottom outlet in conjunction with the guiding mechanism 3, thus removing the powder from the silo 1. During the powder introduction and discharge process, powder splashes inside the silo 1, and excess gas passes through the filter bag 208. The air enters the top of the sump 209 and is filtered by the filter bag 208. Then, the air passes through the inner sump 211, the sponge cylinder 212, the outer sump 210, the support ring 206 and the inclined ring plate 205 in sequence, and is discharged through the gap between the top cover 201 and the inner clamping cylinder 202. When the external air enters the interior, the air passes through the notch of the inclined ring plate 205 and the support ring 206, and is guided into the contact sponge cylinder 212 through the air groove at the bottom of the outer side of the outer sump 210, and is guided into the interior of the silo 1 through the guide groove at the top of the outer side of the inner sump 211.

[0026] In the material guiding mechanism 3, the second motor 33 drives the transmission shaft 35 to rotate, which in turn drives the auger blade 36 to rotate inside the material guiding pipe 34. Through the connection between the arc cover 31 and the connecting pipe 32, the powder in the silo 1 is guided into the material guiding pipe 34 under its own gravity. Then, the rotating auger blade 36 guides the powder out from one end of the material guiding pipe 34. At the same time, during the powder transmission process, the arc shape of the inner wall of the arc cover 31 provides a buffer space for the powder to stay when the material guiding pipe 34 cannot be discharged in time.
