Description

Technical Field

[0001] The utility model belongs to the technical field of dust removal, and in particular relates to a debris blocking and collecting device. Background Art

[0002] During the production process, due to various reasons, such as open-pit mining, transportation and processing of ore, the raw ore produced is often inevitably mixed with various debris, such as plastic bags, sunshade nets, etc. The presence of these debris not only affects the purity of the ore, but also brings many difficulties to the subsequent processing and use.

[0003] When these impurities-containing ores are transported to the user manufacturers, they usually use dust collectors to purify the air in the production environment during the production process to ensure the normal operation of the production line and the health of employees. However, various impurities mixed in these raw ores, especially lightweight and easily floating items such as plastic bags and sunshade nets, are easily sucked into the dust collector.

[0004] Once these debris enter the dust collector, they tend to block the dust discharge channel of the dust collector, causing poor conveying of the pneumatic dust conveying device and even causing dust collector failure. This not only affects the continuity and stability of the production line, increases the maintenance cost of the equipment, but also may cause secondary pollution to the environment.

[0005] Therefore, in response to this problem, it is necessary to develop a device that can effectively remove light debris mixed in the ore, so as to reduce or avoid the debris entering the dust collector, thereby improving the use efficiency and life of the dust collector and ensuring the smooth operation of the production line.

[0042] In order to explain the principle of the present invention in detail, the technical features and advantages are described in detail below:

[0043] The cylindrical structure of the debris collector 10:

[0044] Advantages: The cylindrical structure provides sufficient space for dust-laden air to fully flow and contact the debris blocking member 40, thereby effectively intercepting and collecting light debris.

[0045] Dust-laden air inlet 101 and first pneumatic valve 102:

[0046] Advantages: The flow of dust-laden air entering the debris collector is controlled by a pneumatic valve to ensure that the inlet can be quickly and accurately closed when necessary. The first pneumatic valve 102 mainly serves to cut off the airflow, so as to facilitate air cannon blowing and manual removal of debris.

[0047] Dust-laden air outlet 103 and second pneumatic valve 104:

[0048] Advantages: The outlet flow of air treated by the debris blocking component is controlled by a pneumatic valve to ensure the stable operation of the dust removal system.

[0049] Debris discharge port 105 and filter barrel 20:

[0050] Advantages: The debris discharge port is designed to quickly discharge the intercepted light debris into the filter barrel. At the same time, the design of the filter barrel can further filter and collect these debris. After the third pneumatic valve is closed, it is prevented from re-entering the dust removal pipeline.

[0051] Variable diameter structure of filter barrel:

[0052] Advantages: The variable diameter structure makes the filter barrel more compact while maintaining sufficient capacity, which is beneficial to reducing the floor space and improving space utilization. It also makes the air flow velocity drop rapidly when passing through the large diameter, allowing light debris to sink better, and is also beneficial to the service life of the filter barrel.

[0053] Debris blocking member 40:

[0054] Advantages: The debris blocking component can effectively intercept light debris and prevent it from entering the dust removal system, thereby protecting the normal operation of the dust collector and extending its service life.

[0055] Front tee 50 and rear tee 60:

[0056] Advantages: The tee design allows the dust removal duct to be easily installed and removed from the debris blocking collection device. At the same time, by installing the debris collection component between the front and rear tees, a one-for-one configuration can be achieved to improve production continuity.

[0057] Blocking net as debris blocking component:

[0058] Advantages: The blocking net has a simple structure and can effectively block light debris while allowing airflow and dust to pass smoothly, reducing resistance and improving dust removal efficiency.

[0059] Baffle plate and flow hole:

[0060] Advantages: The flow holes can ensure smooth airflow and filter and intercept light debris.

[0061] In summary, this debris blocking and collection device achieves effective interception and collection of lightweight debris through carefully designed technical features, protects the normal operation of the dust removal system, and improves production efficiency and environmental protection performance.

[0062] Method of using the above debris blocking and collecting device

[0063] 1. Installation and connection

[0064] Installation location selection: During the production process, select an appropriate location on the dust removal pipeline to install the debris blocking and collecting device. It is usually recommended to use one for backup and one for use, that is, install the device on the dust removal pipeline between the front tee and the rear tee.

[0065] Component assembly: Assemble the debris collector, filter barrel, pneumatic valve and other components according to the design drawings; ensure that all connecting parts are firm and reliable without leakage.

[0066] Connect with dust removal pipeline: Connect the debris collector with the dust removal pipeline through the first pneumatic valve and the second pneumatic valve. Make sure the connection is well sealed to prevent air leakage.

[0067] 2. Operation and Adjustment

[0068] Preparation before starting: Check whether the debris blocking and collecting device and its connecting parts are intact, and confirm that all pneumatic valves are in the closed state.

[0069] When the dust removal system is working normally, open the pneumatic valves: open the first pneumatic valve and the second pneumatic valve on one of the branches at the same time; let the dusty air mixed with light debris enter the debris collector through one branch, and then close the third pneumatic valve, the fourth pneumatic valve and the air cannon back-blowing valve; in addition, close all pneumatic valves and air cannon back-blowing valves on the other branch;

[0070] After the dust-laden gas passes through the debris blocking component, various plastic debris in the dust-laden gas mixed with light debris is blocked in the debris collector. The remaining dust-laden gas enters the dust removal pipeline through the dust-laden air outlet and the second pneumatic valve, and then enters the dust collector for dust removal.

[0071] Debris collection: Under the action of dust removal negative pressure, light debris is blocked by the debris blocking component and intercepted on the lower surface of the debris blocking component.

[0072] Debris back-blowing collection, when all kinds of plastic debris are sucked in too much and the debris blocking component is blocked, the pressure difference transmitter alarms. At the same time, the PLC control system controls the first and second pneumatic valves to close. At the same time, the first and second pneumatic valves of the other branch are opened at the same time. At this time, the debris collector on the left starts to clean up; the PLC control system controls the third pneumatic valve on the closed branch to open and close, and starts the air cannon back-blowing valve and opens the air cannon for back-blowing. Compressed air blows the debris off the debris blocking component and enters the filter barrel through the debris inlet of the filter barrel. The dust filter bag in the filter barrel will collect the debris, so the debris is left inside the filter barrel and the compressed air escapes. When there are a lot of debris inside the filter barrel, close the first, second, and third pneumatic valves of the branch, and open the fourth pneumatic valve for cleaning. In order to ensure the normal production process, the two branches are used alternately, the closed branch is used for cleaning, and the open branch ensures continuous dust removal.

[0073] In summary, the utility model realizes the effective interception and collection of debris in the raw ore in the mining production process through the design of the debris blocking and collecting device, improves the performance and service life of the dust collector, reduces maintenance costs, and reduces environmental pollution, with significant economic and environmental benefits.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
