The high-pressure spray dust suppression spray head and the container spray head are arranged on the top lower side of the portal steel frame at the cleaning channel through the spray head adjustment component. The container spray head is used to spray the container. The high-pressure spray dust suppression spray head is used to achieve dust suppression operation. The side spray head is arranged on the inner side of the front and rear sides of the portal steel frame at the cleaning channel and the inner side of the side retaining wall through the spray head adjustment component. The side spray head is used to spray the side of the truck. The chassis spray head is arranged at the bottom of the washing channel through a spray head adjustment assembly, which is used for spraying the chassis and water guide groove of the truck. The angle of the spray head is adjusted based on the spray head adjustment assembly. The high-pressure plunger pump is arranged inside the water circulation recovery assembly. The high-pressure plunger pump is connected to the precision filter. The precision filter is connected to the multi-stage centrifugal pump. The fully automatic washing filter is arranged on the multi-stage centrifugal pump.

[0019] The chassis spray head and the side spray head can clean the sludge in the water channel, which is easy to use.

[0020] The high-pressure plunger pump, through the high-pressure device equipment, adjusts the pressure gauge at the high-pressure outlet of the pump station to control and adjust the water outlet pressure, so as to achieve the water pressure standard required by the high-pressure spray system and ensure the high-pressure spray effect.

[0021] Precision filter (also known as security filter), the shell is generally made of stainless steel, and the internal tubular filter element such as PP filter element is used as the filter element. Different filter elements are selected according to different filter media and design processes to meet the requirements of water quality. Performance characteristics: (1) High filtration accuracy, uniform filter element pore size; (2) Small filtration resistance, large flux, strong pollution interception ability, and long service life; (3) High cleanliness of filter element material, no pollution to the filter medium; (4) Resistant to acid, alkali and other chemical solvents; (5) High strength, high temperature resistance, and the filter element is not easy to deform; (6) Low price, low operating cost, easy to clean, and the filter element can be replaced.

[0022] Fully automatic suction and brush filter, fully automatic suction and brush filter is installed at the outlet of the water pump to remove fine impurities in the main pipeline. The filtration accuracy is 50μm, which is a fine filtration, which can ensure that the system water quality meets the requirements of dry fog and reduce the occurrence of nozzle clogging. The internal structure of the fully automatic suction and brush filter includes stainless steel wire brushes, stainless steel filter screens and transmission parts. The transmission motor and electric valve automatically complete the cleaning and drainage. The operation mode is automatic operation (can also be manually operated), with pressure difference or timed automatic drainage function. When the water flows through the filter, the mechanical impurities in the water are intercepted by the filter screen. When the impurities accumulated on the surface of the filter screen increase and the pressure difference reaches 0.05MPa, the pressure difference type pressure difference switch will send a signal, the transmission motor will start, the drainage valve will open, and the impurities deposited in the filter screen will be brushed down by the rotating brush, sucked out from the suction port, and then discharged from the drainage port. The entire brushing and drainage process does not require personnel operation and does not require shutdown. At the same time, the equipment also has the functions of timed cleaning and drainage and manual cleaning and drainage to ensure safe and reliable water discharge under any circumstances.

[0023] A multi-stage centrifugal pump provides water for the platform cleaning network.

[0024] The connecting pipes of the side spray head, container spray head, high-pressure spray dust suppression spray head and chassis spray head are all provided with corresponding electric control valves, and the corresponding electric control valves can be controlled to open through the control system to realize the corresponding functions.

[0025] The side spray head is set at an angle of 10°, the container spray head and the high-pressure spray dust suppression spray head are set vertically downward, and the chassis spray head is set at an angle of 45°.

[0026] The high-pressure spray dust suppression sprinkler head adopts a special nozzle, which can produce uniform and fine water mist with a diameter of 20~50μm through high-pressure water supply, condense and remove airborne dust particles generated in the process of various material handling. The high-pressure spray dust suppression system uses a special nozzle and a high-pressure water source to form dense water mist particles of 20~50μm, and has a long spray distance and outstanding wind interference resistance, which is suitable for outdoor working conditions. The specific principle is as follows Figure 2 As shown, a single-fluid nozzle that uses a high-pressure water source (5-10MPa) to form a fine water mist. The nozzle is made of 410 stainless steel or a ceramic core, which has good hardness and corrosion resistance; low water consumption; the nozzle has its own filter to prevent clogging; the water mist particles are uniform and the atomization effect is good, 20-50μm at 6MPa water pressure.

[0027] The control system can be controlled by a PLC touch screen to achieve manual and automatic two-way selection and selection of flushing time. For example, an automatic / manual selectable switch can be set, and the flushing time can be adjusted from 20s to 120s. When the cleaning program is started, it can avoid starting multiple pipelines at the same time, and a time interval of ≥0.2 seconds can be set to start / stop different pipelines in sequence, thereby saving water and improving driving safety and vision.

[0028] The water circulation recovery component includes a clear water tank, a pump group tank, a high-efficiency filtration tank, a flocculation aeration tank and a grit tank. A plurality of pump groups are arranged in the pump group tank. The clear water tank, the high-efficiency filtration tank, the flocculation aeration tank and the grit tank are all connected to the pump group. The water in each tank is pumped to a preset location based on the pump group. The grit tank is connected to a water guide trough. The clear water tank is used to provide clear water to the dust suppression and cleaning component. The clear water tank, the high-efficiency filtration tank, the flocculation aeration tank and the grit tank are all provided with a high liquid level switch, a low liquid level switch, a low-low liquid level switch, a stainless steel appendage, a manhole, an inner ladder, a glass tube liquid level indicator and an overflow water pipe. The water in each tank is discharged through the overflow water pipe. The high liquid level switch, the low liquid level switch and the low-low liquid level switch are electrically connected to the control system. Different devices and fillers are arranged in different water tanks according to the process requirements to meet the water treatment process requirements.

[0029] The relevant pump groups of the dust suppression and cleaning components are all arranged in the pump group pool.

[0030] The connecting pipes of the dust suppression and cleaning components and the water recycling and recovery components are both provided with low-temperature constant-temperature electric heating cables, which are electrically connected to the control system. This ensures that dust suppression and wheel cleaning operations can still be performed normally in the freezing season in winter, greatly improving the utilization rate of the equipment and meeting the environmental protection requirements in winter. In addition, a drain valve is provided on each water inlet branch, which can be drained and shut down when not in use in winter to save electricity and energy.

[0031] The specific use process diagram of the present invention is as follows Figure 3 As shown. Through infrared counter-radiation sensing and industrial-grade capture and positioning devices, the vehicle cargo box is positioned, and spraying starts when it is in place, and stops when the cargo box is out of position. After capturing the position of the cargo box, the self-adjusting nozzle positioning system is used to automatically calibrate the nozzle position according to the received vehicle position information. The use of a nozzle structure embedded in the store steel frame can not only avoid wind interference with the spray water, but also has a beautiful shape. Based on multiple water pools, automatic water replenishment facilities, water treatment and water circulation systems can be realized, achieving an unattended full-process automated working mode.

[0032] After experiments, the dust suppression rate on site of this application reached more than 90%. The water consumption of the high-pressure micro-mist device is small, the weight ratio of the increase in material moisture is less than 0.1%, and the energy-saving effect is obvious. It can realize manual and fully automatic control modes. In the automatic operation mode, the programmable logic controller (PLC) of the high-pressure spray device is automatically controlled according to the on-site conditions, and unmanned operation can be realized, reducing the labor intensity of on-site operators. The high-pressure spray device has the function of remotely feedbacking various alarms and operation signals inside the system (including power on, power off, filter blockage, electric heating belt working, low air pressure, low water pressure, high-pressure micro-mist device automatic / manual operation status indication and other signals). In manual operation mode, it can be controlled by the manual button of the on-site high-pressure spray device (used during equipment debugging). When the ambient temperature is lower than +5°C, the electric heating system starts to ensure normal use in winter.
