Description

Technical Field

[0001] This utility model relates to the field of cement production equipment technology, specifically a dust collector for the discharge port of a cement clinker silo. Background Technology

[0002] In the cement production process, the clinker silo discharge port is a critical point for material transfer. However, existing technologies have many problems at this stage. A large amount of dust is generated during discharge, which disperses widely, severely impacting the working environment and posing a threat to the health of operators. Current dust collectors at the clinker silo discharge port often rely solely on air pumps for dust collection, a method with significant shortcomings.

[0003] On the one hand, due to the high speed and large drop of cement clinker, a large amount of dust is easily generated when it falls. It is difficult for air pumps alone to quickly and comprehensively absorb all the dust, resulting in some dust overflowing and polluting the environment. On the other hand, after the air pump has been extracting dust for a long time, a large amount of dust will be attached to the dust collection bag. If it is not cleaned in time, it will easily cause blockage, greatly reducing the dust collection efficiency. Moreover, the collected dust lacks a convenient structure for discharge and recycling, which not only affects the production environment but also causes resource waste.

[0004] Furthermore, the existing dust collectors lack effective buffer structures, failing to reduce dust generation at the source and further exacerbating dust collection pressure. Therefore, it is urgent to improve the dust collectors at the discharge port of a cement clinker silo to solve the above problems. Utility Model Content

[0009] Preferably, the upper end of the dust collection hood is provided with a second flange, and the second flange is fixedly installed on the first flange by bolts. The first flange is located at the lower end of the second connecting sleeve.

[0010] Preferably, the second connecting sleeve is movably installed inside the first connecting sleeve, the first connecting sleeve has limiting edges at its upper and lower ends, and the second connecting sleeve has locking blocks at its upper and lower ends that cooperate with the limiting edges.

[0011] Preferably, a buffer plate is movably installed inside the second connecting sleeve, and rotating shafts are fixedly installed on both sides of the buffer plate. The inner side of the second connecting sleeve is provided with a mounting seat that cooperates with the rotating shaft to rotate. A limit disc is fixedly installed at the end of the rotating shaft, and a locking bolt is movably installed on the outer side of the second connecting sleeve by means of threads.

[0012] Preferably, the dust collection mechanism includes a mounting frame and a stainless steel pipe. An air pump is fixedly mounted on the mounting frame.

A chamber door is fixedly mounted on the front section of the piston rod of the second cylinder, and a dust outlet is provided in front of the chamber door.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The dust collector at the discharge port of this cement clinker silo has a buffer mechanism that uses a cylinder-driven baffle to adjust the falling speed of the cement clinker, preventing dust from being generated due to excessively fast discharge. Combined with the rotating shaft mounting structure of the buffer plate, the buffer angle can be flexibly adjusted and fixed with locking bolts, effectively buffering the falling cement clinker to reduce the drop height, thereby reducing dust generation at the source and minimizing dust problems during cement clinker discharge.

[0015] 2. The dust collector at the discharge port of this cement clinker silo uses an air pump and dust collection pipe to extract dust from the filter bags and collect it into the dust collection bin, efficiently adsorbing dust generated during the discharge process. The vibrating motor vibrates the filter bags, causing the dust adhering to them to fall off, preventing blockage and maintaining dust collection efficiency. The cylinders on the stainless steel pipes drive the bin door to open and close, and together with the dust outlet, the collected dust can be easily discharged, realizing centralized treatment and recycling of dust. The overall structure improves the thoroughness of dust collection and the convenience of operation, effectively reducing dust pollution to the environment. Attached Figure Description

[0023] Example 1:

[0024] Based on existing technology, current dust collectors lack effective buffer structures, failing to reduce dust generation at the source and further exacerbating dust collection pressure. Therefore, this device incorporates a buffer mechanism. Please refer to [link / reference needed]. Figures 1-4This utility model provides a technical solution: a dust collector for the discharge port of a cement clinker silo, including a mounting frame 1, a cement clinker silo 2 fixedly mounted on the top of the mounting frame 1 via a mounting flange 3, a dust collection component 4 provided behind the cement clinker silo 2, the discharge port of the cement clinker silo 2 passing through the mounting frame 1, and a discharge pipe 5 provided below it; the dust collector for the discharge port of a cement clinker silo includes a buffer mechanism and a dust collection mechanism, the buffer mechanism includes the mounting frame 1, a cylinder 201 fixedly mounted on the mounting frame 1, the piston rod 202 of the cylinder 201 fixedly mounted on a baffle 203 inside the mounting flange 3, a winch 204 fixedly mounted on the top inner side of the mounting frame 1, a steel cable 205 and a winch motor provided inside the winch 204, and a limit block 207 fixedly mounted at the end of the steel cable 205.

[0025] A pulley 206 is fixedly installed at the front end of the winch 204, and a steel cable 205 passes through the pulley 206. A cloth bag 209 is fixedly installed at the center of the inner side of the mounting frame 1. Multiple sets of mounting steel frames 208 are evenly and longitudinally installed on the cloth bag 209, and the steel cable 205 passes through the mounting steel frame 208.

[0026] The lowest end of the cloth bag 209 is fixedly connected to a stainless steel pipe 210, and the bottom end of the stainless steel pipe 210 is fixedly connected to a dust collection hood 219 by bolts. The dust collection hood 219 is provided with multiple sets of through grooves.

[0027] The upper end of the dust collection hood 219 is provided with a flange 217. The flange 217 is fixedly installed on the flange 216 by bolts 218. The flange 216 is located at the lower end of the connecting sleeve 213.

[0028] Connecting sleeve 213 is movably installed inside connecting sleeve 1 211. Connecting sleeve 1 211 has limiting edges 212 at both the upper and lower ends, and connecting sleeve 213 has locking blocks at both the upper and lower ends that cooperate with the limiting edges 212.

[0029] A buffer plate 214 is movably installed inside the connecting sleeve 213. A rotating shaft 215 is fixedly installed on both sides of the buffer plate 214. A mounting seat that rotates with the rotating shaft 215 is provided on the inner side of the connecting sleeve 213. A limit disc 220 is fixedly installed at the end of the rotating shaft 215. A locking bolt 221 is movably installed on the outer side of the connecting sleeve 213 by means of threads.

[0030] Cylinder 201 on mounting frame 1 is activated, and its piston rod 202 drives the baffle 203 inside mounting flange 3 to move. By changing the gap between baffle 203 and the discharge port of cement clinker silo 2, the falling speed of clinker is adjusted to avoid excessive dust caused by excessive discharge. The winch 204 (including winch motor) on the inner top of mounting frame 1 is activated, and the steel cable 205 changes direction through the pulley 206 at the front end and passes through the mounting steel frame 208 on the cloth bag 209. When the winch motor rotates forward / reverse, the steel cable 205 tightens / unwinds, causing the mounting steel frame 208 (and cloth bag 209) to make slight up-and-down adjustments. The limit block 207 at the end prevents excessive movement and ensures that the discharge port connects with the receiving car below. The buffer plate 214 inside the second pipe 213 can rotate around the rotating shafts 215 on both sides. The rotating shafts 215 cooperate with the mounting seats inside the second connecting sleeve 213. By rotating the buffer plate 214, the tilt angle can be adjusted to adapt to different clinker particle sizes. After the angle is determined, tighten the locking bolts 221 on the outside of the second connecting sleeve 213 to press against the limiting disc 220 at the end of the rotating shaft 215, thereby fixing the buffer plate 214 and reducing dust generation from the source. The dust collection hood 219 at the bottom of the stainless steel pipe 210 is bolted to the flange 216 of the second connecting sleeve 213 through flange 217. The multiple sets of through grooves on its surface can guide the scattered dust to initially gather, reduce overflow, and facilitate subsequent dust collection treatment.

[0031] Example 2:

[0032] Based on Example 1, existing dust collectors at the discharge port of cement clinker silos often rely solely on air pumps for dust collection. This method has significant shortcomings: Firstly, due to the high speed and large drop of cement clinker during descent, a large amount of dust is easily generated, and air pumps alone cannot quickly and comprehensively absorb all the dust, leading to some dust overflowing and polluting the environment. Secondly, after prolonged dust extraction, a large amount of dust accumulates on the dust collection bags. If not cleaned promptly, this can easily cause blockages, significantly reducing dust collection efficiency. Furthermore, the collected dust lacks a convenient structure for discharge and recycling, impacting the production environment and wasting resources. Please refer to... Figures 1-5 Therefore, this device is equipped with a dust collection mechanism. This utility model provides a technical solution: a dust collector for the discharge port of a cement clinker silo. The dust collection mechanism includes a mounting frame 1 and a stainless steel pipe 210. An air pump 301 is fixedly installed on the mounting frame 1. The air pump 301's exhaust port is fixedly connected to a dust collection bin 302 through an air pipe. A dust collection pipe 303 is fixedly installed at the dust extraction port of the dust collection bin 302. The other end of the dust collection pipe 303 is fixedly installed on the upper end of a cloth bag 209. A vibration motor 304 is fixedly installed on the side of the stainless steel pipe 210, and a second cylinder 305 is fixedly installed on the other side. A bin door 306 is fixedly installed on the front section of the piston rod of the second cylinder 305. A dust outlet 307 is provided in front of the bin door 306.

[0033] The air pump 301 on the mounting frame 1 is started, and the dust is drawn from the filter bag 209 to the dust collection chamber 302 through the dust collection pipe 303. This achieves centralized dust collection. The vibration motor 304 on the stainless steel pipe 210 works, and the vibration is transmitted to the filter bag 209, causing the dust adhering to the inner wall of the filter bag 209 to fall off, avoiding clogging of the filter bag and maintaining dust collection efficiency. When the dust in the dust collection chamber 302 or the stainless steel pipe 210 needs to be treated, the cylinder 305 is started, and its piston rod drives the chamber door 306 to move, opening the dust outlet 307. The dust is discharged through the dust outlet 307, realizing convenient recycling and reuse, reducing resource waste and environmental pollution.
