The dust suppression vehicle belongs to a kind of spray dust suppression and curing agent device at the coal shipment point and mainly serves iron, roads and other fields. When the train transports coal, the dust suppression car can cure the coal on each train, form a protective film, and reduce pollution.
The main purposeDust suppression vehicles are used for the prevention and control of coal dust pollution in railway coal transportation. They are also widely used in the prevention of dust pollution in other bulk materials transportation processes, and in slag yards, coal storage yards, construction sites, coal transportation dust, sand stabilization, iron and steel building materials, cement, and enterprises. All kinds of open-air stockyards, such as ecological slope protection.
FeaturesThis type of vehicle also has a sprinkler function, which can achieve 360-degree rotation during spraying operation. The rear platform antiaircraft gun can be rotated at the same time and can be operated electronically remotely.
Dust suppression vehicle structure and working principleIn terms of construction, the dust suppression vehicle is mainly composed of a swing arm spray device, a liquid storage tank, a self-propelled vehicle, and a control system.
In winter in northern regions, tanks, spray nozzles, and pump bodies need to be pretended to be heat-preservation heating systems in order to operate properly.
The dust suppression vehicles mainly use the interaction between the hydraulic system and the electronic control system. That is, the mobile spray equipment injects the spray fluid into the liquid storage tank at the dispensing station and goes to the spraying point; when the train passes, the photoelectric detection system starts to identify the traction vehicle. After the traction locomotive passes, a signal is issued, and the control personnel controls the transmission hydraulic system to rotate the liquid pipe and the carriage body orthogonally, and at the same time, start the liquid pump to start spraying. And adjust the liquid pump flow to meet the design spray standard. The photoelectric detection system sends a signal to the PLC between the uncoupled gears of the train to control the stepping motor or the servo motor to stop spraying and spraying by rotating the shielding drum through the transmission connection device. When the train passes completely, the device stops spraying.
Patent levelThe new multifunctional dust suppression sprayer will serve the Ministry of Railways or other more fields. It is mainly the train that transports coal to cure the coal on each train, form a protective film, and reduce pollution. The spray can rotate 360 ​​degrees with a sprinkler function, and the rear platform cannon can rotate at the same time. Remotely operated electronically.
Principle of operation: Dust and dust scattering along coal trains cause serious environmental problems. Spraying dust suppression agents on coal trains can effectively prevent the loss of coal caused by rapid train travel and environmental pollution. According to the characteristics and technical requirements of coal railway transportation, combined with the physical properties of dust suppression agent, a design proposal for dust suppression agent spraying equipment was proposed. The nozzle was designed and the spray performance was simulated and experimentally studied.
According to the technical requirements of dust suppression agent spray equipment for coal trains on railway lines, dust suppression equipment was designed and the strength and stiffness of the mechanical components of the equipment were analyzed with ANSYS software.
According to the performance of the dust suppression agent, the spray performance of the nozzle was studied through numerical simulation and experiments, and the nozzle used for spraying dust suppression agent was selected. On this basis, four kinds of nozzles were selected for the experimental comparison of the spraying effect, and a nozzle with good spraying effect was selected for the dust suppression agent spraying device. The fluid piping system of the spray equipment was designed and hydraulically calculated, and a suitable water pump was selected; the piping characteristics of the system were analyzed to determine the performance curve equation of the pipeline system with the flow rate of the spray piping system, and the flow and pump were deduced. The relationship of speed, provides a basis for the pump speed control system design.
This vehicle is a new type of environmental protection dust prevention product and its prevention equipment developed for the coal dust pollution of railway coal transportation. The dust suppression agent has the characteristics of being non-toxic, odorless, and non-corrosive. After being sprayed on the surface of the coal seam by the coal train automatic spraying system, a solidified layer having a certain strength and toughness can be formed, and dust can be effectively prevented. Anti-dusting dust automatic spraying system for coal trains can be sprayed during vehicle operation. The development of this product and its equipment solves the problem of coal dust pollution on the surrounding ecological environment during the operation of the vehicle and reduces the direct loss of coal. And the company has brought huge economic benefits
