Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aggregate silo dust removal equipment in a mixing station, in particular to a high-efficiency aggregate silo dust removal system. Background Art
[0002] Aggregate silo dust removal is a key task in dry aggregate support systems, aimed at reducing or eliminating dust generated during the storage and handling of aggregates (such as sand, gravel, etc.). This dust not only pollutes the environment but can also pose a threat to worker health. Therefore, an effective dust removal system is crucial to ensuring a safe and environmentally friendly work environment. 1. Types of Dust Removal Equipment: 1.1 Mechanical Dust Collector: Utilizes centrifugal force to separate dust from the airflow and is suitable for larger dust particles. Inertial Separator: Redirects the airflow, causing dust to separate due to inertia and is suitable for medium-sized dust particles. 1.2 Filter Dust Collector, Baghouse Dust Collector: Utilizes fiber filter bags to capture dust and is suitable for fine dust particles, offering high dust removal efficiency. Electrostatic Precipitator: Electrostatically attracts dust particles to electrode plates and is suitable for fine dust particles, particularly well-suited for handling high-temperature gases. 1.3 Wet Dust Collector, Scrubber: Uses a spray of water or chemical solutions to capture dust and is suitable for dust containing moisture. Foam dust collector: This system uses foam to capture dust and is suitable for fine dust particles. Properly designed and maintained aggregate silo dust collection systems can effectively reduce dust pollution, protect the environment and worker health, and improve production efficiency and economic benefits.
[0003] Many sand and gravel materials are produced using a dry process and contain a high amount of stone dust. When sand and gravel are transported to a silo for storage, they are fed directly into the silo via a belt conveyor. To prevent dust from escaping, the entire feed channel and feeding point are enclosed by a dust collector installed in an opening in the enclosure. When the dust collector is activated, the air inside the enclosure is under negative pressure, preventing dust from escaping.
[0004] However, since the enclosure is a closed cavity, clean air cannot enter, making it impossible to quickly exchange the dust-laden gas inside the enclosure. If the closed cavity is too large, the dust collector can only quickly collect the gas near the dust collection port, and the suction effect on dust in remote areas or corners is not very good, thus failing to achieve the purpose of rapid dust collection. This also makes it impossible to monitor the material level and feeding status in real time.
[0005] Therefore, there is an urgent need to design an efficient aggregate silo dust removal system to solve the problems of poor sealing and dust removal effect and low dust removal efficiency of the existing aggregate feeding belt conveyor dust removal device. Utility Model Content

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely further describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0025] like Figures 1-4 As shown, an efficient aggregate silo dust removal system includes a sealing cover 1 and a dust collector 2. The sealing cover 1 is installed on the top of the aggregate silo 6. The upper part of the sealing cover 1 is connected to the feeding belt conveyor 3. The middle part of the sealing cover 1 is provided with a feeding port, which is connected to the feeding port of the feeding belt conveyor 3 through a sealing flexible connection 4. The sealing flexible connection 4 adopts a soft rubber tube. The upper part of the sealing flexible connection 4 is fixed to the lower part of the feeding port of the feeding belt conveyor, and the lower part of the sealing flexible connection 4 extends into the feeding port of the sealing cover 1.
[0026] A rotary material distribution belt conveyor 5 is installed below the sealing flexible connection 4 , the rotary material distribution belt conveyor 5 is located inside the sealing cover 1 , and the rotary material distribution belt conveyor 5 is installed on the top of the aggregate bin 6 , and the rotary material distribution belt conveyor 5 rotates to distribute materials into the aggregate bin 6 .
[0027] A dust collector 2 is installed at one corner of the upper portion of the sealing cover 1 , a dust collecting cover 2.1 of the dust collector 2 is installed on the upper portion of the feeding belt conveyor 3 , and a discharge port of the dust collector 2 is installed in the sealing cover 1 .
[0028] The dust removal cover 2.1 of the dust collector 2 is installed at the unloading port of the feeding belt conveyor 3. The upper part of the dust removal cover 2.1 is connected to the dust collector 2 through the dust removal pipe 2.2. The lower part of the dust collector 2 is installed on the sealing cover 1, and the unloading port of the lower part of the dust collector 2 extends into the sealing cover 1.
[0029] The sealing cover 1 is further provided with three air vents 1.1 , which are all arranged at positions away from the discharge port of the dust collector 2 .
[0030] A damper 1.2 is installed at the air outlet 1.1. The inner side of the air outlet 1.1 is rotatably connected to the damper 1.2 through a pin shaft 1.3. The lower part of the air outlet 1.1 is fixedly connected to a counterweight rod 1.4, and a plurality of counterweight blocks 1.5 are installed on the counterweight rod 1.4.
[0031] The working principle of this utility model:
[0032] The feeding conveyor 3 feeds sand and gravel into the rotary feeding conveyor 5 in the sealing cover 1 through its own feeding chute. The rotary feeding conveyor 5 feeds the sand and gravel to the aggregate bin 6 through its own rotation. The feeding conveyor 3 and the sealing cover 1 are connected by a sealed soft connection. The feeding area on the top of the aggregate bin 6 is sealed by the sealing cover 1, and the entire feeding process is within the sealed area. The dust collector 2 collects dust from the feeding point of the feeding conveyor 3 through the dust collection pipeline. The wind pressure of the dust collector absorbs dust from the sealing cover. The dust collector 2 collects dust from the feeding area in the sealing cover 1 through the discharge port of its own dust collecting hopper. The feeding and feeding are fully enclosed and the dust collection is automatic.
[0033] The ventilation damper design includes the position design of the damper 1.2 and the counterweight design of the damper 1.2; the damper 1.2 is installed at a corner position 3 which is relatively far away from the dust collection port of the dust collector 2 or is not easy to collect dust. The counterweight adjustment device of the damper 1.2 controls the opening pressure of the damper 1.2 by the number of counterweight blocks 1.5. When the counterweight blocks 1.5 are small, the dust collector 2 forms a negative pressure in the sealing cover 1 to open the damper 1.2 inward to let in air, so that the damper 1.2 can reasonably enter clean air when the dust collector 2 is working, and utilizes the change in wind speed and pressure difference from the dust collection port to the damper to realize that the incoming clean air can quickly push the dust-laden gas toward the dust collection port of the dust collector 2, thereby realizing rapid dust collection in the sealing cover 1.
