Description

Technical Field

[0001] The utility model relates to the technical field of cement silo unloading devices, in particular to an anti-blocking unloading device for a cement silo. Background Art

[0002] Cement is an important building material, and during the production process, the produced cement needs to be stored in a silo in advance for subsequent packaging or bulk delivery. However, during the static storage of cement, more or less cement lumps will be generated in the cement silo, which will cause the discharge pipe to be blocked. The existing Chinese patent with publication number CN210479666U discloses a cement silo unloading device: the patent puts cement into the lower cone through the feed port, and then the driving motor rotates forward through the rotating shaft to drive the line roller, and the line roller drives the connecting plate and the lower cone to descend through the pull rope, and then the buffer spring in the bottom ring is compressed by force, and then the driving motor is reversed, and the buffer spring in the bottom ring is compressed to generate a recoil force, so that the lower cone rises, thereby achieving the purpose of shaking the lower cone up and down, so that the cement in the lower cone is easily discharged through the discharge port.

[0003] However, the above-mentioned prior art solutions also have the following defects:

[0004] Although the existing device facilitates cement discharge by shaking the lower cone, cement is easy to agglomerate during storage, causing unloading blockage, which still affects unloading. In addition, a large amount of dust is generated during unloading, polluting the environment and affecting the health of personnel when inhaled. Utility Model Content

The stirring rod is convenient for stirring the cement to prevent cement caking and causing unloading blockage. The spiral blade is convenient for conveying cement to prevent blockage at the unloading pipe. By setting a unloading buffer component, a buffering effect is played on the falling cement, preventing the large impact force of the cement falling directly on the conveyor from causing damage to the conveyor.

[0025] In the present embodiment, a cement silo anti-blocking unloading device comprises a dustproof box body 1, which can shield the dust generated when the silo 3 is unloaded, so that most of the dust is concentrated inside the dustproof box body 1, the upper end of the dustproof box body 1 is provided with a silo 3, one side of the silo 3 is provided with a water tank 2, a conveyor 4 is provided inside the dustproof box body 1, and a material unloading buffer assembly 5 is provided above the conveyor 4, a cover plate 301 is provided at the upper end of the silo 3, a first motor 302 is installed on the cover plate 301, a main shaft 303 is provided on the output end of the first motor 302, a stirring rod 304 is fixedly provided on the outer wall of the main shaft 303, a spiral blade 305 is provided below the stirring rod 304, and the spiral blade 305 is fixedly connected to the main shaft 303, and the bottom of the silo 3 A discharge pipe 307 is fixedly provided, and the discharge pipe 307 is located inside the dustproof box 1. A limit slot 306 is fixedly provided at the front end of the discharge pipe 307, and a movable sealing plate 6 is provided at the lower end of the discharge pipe 307. After cement is put into the silo 3, the first motor 302 is started, and its output end drives the main shaft 303 to transmit, thereby driving the stirring rod 304 and the spiral blade 305 to rotate together. The stirring rod 304 is convenient for stirring the cement to avoid cement agglomeration causing discharge blockage. The spiral blade 305 is convenient for conveying cement to prevent blockage at the discharge pipe 307. The sealing plate 6 is manually moved to control the discharge of the silo 3. When the discharge pipe 307 needs to be sealed, one end of the sealing plate 6 is moved into the limit slot 306 to limit and fix the sealing plate 6.

[0026] In this embodiment, the unloading buffer assembly 5 includes a second motor 501, a rotating shaft 502 and a buffer baffle 503. The second motor 501 is installed on the rear end face of the dustproof box 1. One end of the rotating shaft 502 is transmission-connected to the output end of the second motor 501. The buffer baffle 503 is arranged on the outer wall of the rotating shaft 502. By starting the second motor 501, its output end drives the rotating shaft 502 to transmit, thereby driving the buffer baffle 503 to rotate. When cement falls on the buffer baffle 503, as the buffer baffle 503 rotates, the cement enters the space between adjacent buffer baffles 503 until it falls on the belt of the conveyor 4. The unloading buffer assembly 5 has a buffering effect on the falling cement, thereby preventing the large impact force of the cement falling directly on the conveyor 4 from causing damage to the conveyor 4.

[0027] A material guide scraper 401 is provided on one side of the conveyor 4, and the material guide scraper 401 is fixedly connected to the dustproof box 1.

At the same time, one end of the material guide scraper 401 contacts the belt of the conveyor 4, and can scrape off the cement attached to the belt.

[0028] In this embodiment, a water inlet pipe 201 is provided at the upper end of the water tank 2, a dust pump 202 is installed at the rear end of the water inlet pipe 201, a suction pipe 204 is fixedly connected to one side of the dust pump 202, one end of the suction pipe 204 extends to the inside of the dustproof box 1 and is connected to a dust cover 207, a filter is provided at one end of the suction pipe 204 near the dust cover 207, an air supply pipe 205 is fixedly connected to the other side of the dust pump 202, and one end of the air supply pipe 205 extends to the inside of the water tank 2, an exhaust port 203 is provided on the upper end surface of the water tank 2, an activated carbon adsorption net 206 is provided inside the exhaust port 203, and the activated carbon adsorption net 206 is provided through the water inlet pipe 20 1 injects clean water into the water tank 2, and then starts the dust suction pump 202, so as to remove the dust generated by unloading in the dustproof box 1, and the dust enters the suction pipe 204 through the dust suction cover 207. The filter net in the suction pipe 204 can block the impurity particles in the dust. Then, the air is sent into the water tank 2 through the air supply pipe 205 for purification under the action of the dust suction pump 202. After the air contacts with the water, the water quickly filters the dust in the air. Then, the air in the water tank 2 is exhausted through the exhaust port 203. When passing through the exhaust port 203, the activated carbon adsorption net 206 can adsorb the odor molecules in the air, thereby ensuring that the exhausted air will not pollute the environment.

[0029] Working principle: when in use, cement is put into the silo 3, and the first motor 302 is started. Its output end drives the main shaft 303 to transmit, and then drives the stirring rod 304 and the spiral blade 305 to rotate together. The stirring rod 304 is convenient for stirring the cement to avoid cement caking and causing material discharge blockage. The spiral blade 305 is convenient for conveying cement to prevent blockage at the discharge pipe 307. The sealing plate 6 is manually moved by pulling the handle to make the sealing plate 6 away from the limit slot 306. The cement falls normally on the discharge buffer assembly 5, and the second motor 501 is started. The output end of the second motor 501 drives the rotating shaft 502 to transmit, and then drives the buffer baffle 503 to rotate. When the cement falls on the buffer baffle 503, as the buffer baffle 503 rotates, the cement enters the space between adjacent buffer baffles 503 until it falls on the belt of the conveyor 4, and the belt guides the scraper 401 The dustproof box 1 is driven in the direction of the conveyor to transport the cement. The dustproof box 1 can block the dust generated when the silo 3 is unloaded, so that most of the dust is concentrated inside the dustproof box 1. Clean water is injected into the water tank 2 through the water inlet pipe 201, and then the dust suction pump 202 is started to remove the dust generated by unloading in the dustproof box 1. The dust enters the suction pipe 204 through the dust suction cover 207. The filter net in the suction pipe 204 can block the impurity particles in the dust. Then, the air is sent into the water tank 2 through the air supply pipe 205 for purification under the action of the dust suction pump 202. After the air contacts the water, the water quickly filters the dust in the air. Then, the air in the water tank 2 is exhausted through the exhaust port 203. When passing through the exhaust port 203, the activated carbon adsorption net 206 can adsorb the odor molecules in the air, thereby ensuring that the exhausted air will not pollute the environment.
