Description

Technical fields:

[0001] This utility model belongs to the field of dust removal in material silos, and in particular relates to a dust removal system for material silos in mixing plants. Background technology:

[0002] The mixing plant silo is a key piece of equipment in a concrete mixing plant, mainly used to store powdery materials such as cement, sand, and stone.

[0003] During the operation of the mixing plant's silos, various powdery materials are temporarily stored in their corresponding storage hoppers by a loader. During this filling process, a large amount of dust is generated. In order to reduce the harmful impact of dust on the environment and personnel, existing technologies usually install bag filters in the silos to collect the dust. Although bag filters have a certain dust removal effect, their dust removal effect and range are limited. Because the dust is not effectively blocked and restrained, a large amount of dust still spreads inside the mixing plant's silos, causing serious pollution to the environment inside and outside the silos and damaging the health of on-site workers. Summary of the Invention:

[0004] The purpose of this utility model is to provide a dust removal system for mixing plant silos, which overcomes the shortcomings of the prior art and effectively solves the existing problem of dust pollution in mixing plant silos.

[0005] The present invention relates to a dust removal system for a mixing plant silo, comprising a silo, wherein several storage hoppers are arranged side by side within the silo, and a dust-blocking shed is installed above the storage hoppers. Dust removal water pipes are laid along the top and side walls of the entrance of the dust-blocking shed, and several atomizing nozzles are evenly installed along the length of the dust removal water pipes. Branch pipes are connected to the dust removal water pipes, and the branch pipes are connected to the main water supply pipe, which is connected to the atomization control system.

[0006] Furthermore, the atomization control system includes an atomization electrical control box and a high-pressure pump. The input end of the main water supply pipe is connected to the output end of the high-pressure pump, the input end of the high-pressure pump is connected to the water storage tank, and the top of the water storage tank is connected to the water replenishment pipe.

[0007] Furthermore, an infrared sensor is installed on the top wall of the silo's inlet. The infrared sensor is connected to the PLC control box, which in turn is connected to the atomizing electrical control box.

[0008] Furthermore, a dust detection sensor is installed on the top wall of the inner cavity of the dustproof shed, and the dust detection sensor is connected to the PLC control box.

[0009] Furthermore, it also includes a bag filter dust collection system, which includes a bag filter dust collector. A dust suction port is provided on the top wall of the dust-blocking shed. A dust collection hood is installed on the dust suction port. A dust suction branch pipe is connected to the dust collection hood. The dust suction branch pipe is connected to the main dust suction pipe. The output end of the main dust suction pipe is connected to the bag filter dust collector.

[0010] Furthermore, the electrical control device of the bag filter is connected to the PLC control box.

[0011] The beneficial effects of this utility model are as follows: the dust-blocking canopy set on the storage hopper can block and reduce the spread of dust. At the same time, the water mist curtain sprayed by the bag filter and atomizing nozzle can effectively block the large-scale spread of dust, thereby avoiding serious damage to the environment inside and outside the silo caused by dust, and protecting the health of on-site personnel. Furthermore, under the control of multiple sensors and PLC, intelligent dust removal is achieved, reducing energy consumption and water waste. Attached image description:

Detailed implementation method:

[0016] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings:

[0017] like Figures 1 to 3As shown, a dust removal system for a mixing plant silo includes a silo 1, within which several storage hoppers 2 are arranged side-by-side. A dust-blocking canopy 3 is installed above each storage hopper 2. Dust-collecting water pipes 4 are laid along the top and side walls of the entrance to the dust-blocking canopy 3. Several atomizing nozzles 5 are evenly installed along the length of the dust-collecting water pipes 4. Branch pipes 6 are connected to the dust-collecting water pipes 4 and are connected to a main water supply pipe 7. The main water supply pipe 7 is connected to an atomization control system, which includes an atomization electrical control box and a high-voltage... Pump 8, the input end of the water supply main pipe 7 is connected to the output end of the high-pressure pump 8, the input end of the high-pressure pump 8 is connected to the water storage tank 9, the top of the water storage tank 9 is connected to the water replenishment pipe 10, an infrared sensor 11 is installed on the top wall of the inlet of the silo 1, the infrared sensor 11 is connected to the PLC control box 12, the PLC control box 12 is connected to the atomizing electrical control box, a dust detection sensor 13 is installed on the top wall of the inner cavity of the dustproof shed 3, the dust detection sensor 13 is connected to the PLC control box 12.

[0018] Specifically, the dust-blocking canopy 3 installed on the storage hopper 2 can reduce the spread of dust, while the water mist curtain sprayed by the atomizing nozzle 5 can block the large-scale spread of dust.

[0019] In actual use, the loader in hopper 1 loads various materials into the corresponding storage hoppers 2. When the loader scoops up materials and moves to the dust shed 3 for loading, the infrared sensor 11 detects the loader's approach and transmits a signal to the PLC control box 12. At this time, the PLC control box 12 controls the atomizing control box to start the high-pressure pump 8. The high-pressure pump 8 delivers water from the water tank 9 to the water supply main pipe 7, and sprays water mist through the atomizing nozzles 5. Along the dust removal water pipes 4 laid on the top and side walls at the entrance of the dust shed 3, the water mist sprayed by several atomizing nozzles 5 forms a water mist curtain at the entrance of the dust shed 3. Under the enclosure of the dust shed 3 and the water mist curtain, the loader... When the bucket extends into the dust-blocking shed 3 to load material, the dust generated cannot diffuse outwards in large quantities. Under the continuous adsorption and suppression of the water mist curtain, the dust is eliminated. After the loader finishes loading and moves away from the monitoring area of ​​the infrared sensor 11, the PLC control box 12 sends a signal, and the atomizing control box and high-pressure pump 8 stop working after a delay of several seconds. This process not only effectively suppresses the diffusion of dust, but also realizes intelligent dust removal, reducing energy consumption and water waste. The dust detection sensor 13 can further monitor the concentration of residual dust in the dust-blocking shed 3. If the dust concentration is high, the PLC control box 12 will extend the working time of the atomizing control box and high-pressure pump 8, thereby further effectively suppressing dust.

[0020] like Figures 1 to 3As shown, a dust removal system for a mixing plant silo also includes a bag filter system. The bag filter system includes a bag filter 14. A dust suction port is provided on the top wall of the dust-blocking shed 3. A dust collection hood 15 is installed on the dust suction port. A dust suction branch pipe is connected to the dust collection hood 15. The dust suction branch pipe is connected to the dust suction main pipe 16. The output end of the dust suction main pipe 16 is connected to the bag filter 14. The electrical control device of the bag filter 14 is connected to the PLC control box 12.

[0021] Specifically, the bag filter system can further adsorb dust, thereby improving the dust removal effect of the mixing plant's silos.

[0022] In actual use, when the PLC control box 12 receives signals from the infrared sensor 11 and the dust detection sensor 13, the PLC control box 12 simultaneously instructs the electrical control device of the bag filter 14 to start. The dust collection hood 15 sucks the dust generated in the dust baffle 3 into the dust suction pipe 16 and finally transports it to the bag filter 14 for filtration, thereby further improving the dust removal effect.

[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
