Description

Technical Field

[0001] This utility model relates to the field of car wash equipment technology, specifically to a coal sludge washing device based on a coal truck. Background Technology

[0002] Currently, the car wash equipment mainly consists of two horizontal water spray pipes at the bottom and two horizontal water spray pipes on the side walls. Spray nozzles are evenly spaced on the pipes. Wastewater from the wash flows into a sedimentation tank through a drainage collection pipe for sedimentation and recycling. However, existing car wash equipment has encountered problems in actual operation, including nozzle clogging, incomplete vehicle cleaning, and water waste. Due to the high frequency of car washes, the sedimentation process is not fully completed, allowing some mud and sand to enter and clog the nozzles. Furthermore, the two horizontal water spray pipes on the side walls are too low, resulting in a small and incomplete cleaning area. These problems severely affect the washing effect and efficiency, requiring vehicles to be washed a second time, leading to water waste. Vehicles that are not thoroughly cleaned before leaving the facility and entering the city cause road pollution and negatively impact the urban environment.

[0003] Therefore, in order to solve the above problems and overcome the shortcomings of existing technologies, there is an urgent need for an improved and optimized coal sludge washing device for coal trucks, which can improve the washing effect and efficiency, and avoid resource waste and environmental pollution. Utility Model Content

[0004] This utility model aims to provide a coal sludge washing device for automobile coal trucks. By improving the layout of the nozzles, the water spray structure, and the road surface construction, it solves the problems of easy clogging of the nozzles and insufficient cleaning height leading to poor cleaning effect and waste of resources, thereby improving the washing effect and efficiency of the vehicle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A coal slurry washing device based on a coal truck includes a hardened base plate, a sedimentation tank, and a water supply pipe. It also includes retaining walls, spray pipes, and a drainage collection ditch. The retaining walls are located on both sides of the base plate, and the cross-section of the base plate is an inverted trapezoid. The drainage collection ditch is arranged along the length of the base plate, and oscillating strips are symmetrically and evenly spaced on both sides of the base plate. The spray pipes include at least two bottom spray pipes and at least ten vertical spray pipes. The vertical spray pipes are symmetrically and evenly spaced and fixed to the retaining walls on both sides. The bottom spray pipes are installed on both sides of the drainage collection ditch. One end of the drainage collection ditch is connected to the sedimentation tank. Water spray holes are evenly spaced on the side walls of the vertical spray pipes parallel to and away from the retaining wall and the side walls of the bottom spray pipes parallel to and away from the base plate.

[0007] The principles and advantages of this scheme are:

[0008] To address the shortcomings of the original technical solution, the structure of the spray pipe was modified. The original nozzles were discarded, and spray holes were directly created in the pipe wall to solve the nozzle clogging problem. The two horizontally installed spray pipes on the wall were replaced with ten vertical spray pipes, which were symmetrically and evenly spaced on both sides of the retaining wall, increasing the cleaning coverage area. Because the coal sludge on the vehicles is firmly adhered, it cannot be directly washed away during rinsing. Therefore, symmetrical and evenly spaced vibration strips were installed on the bottom plate on both sides of the drainage collection ditch. When the vehicle to be washed drives in the area with vibration strips, the vibration loosens or dislodging the adhered coal sludge, allowing the high-pressure water flow from the vertical and bottom spray pipes to clean the vehicle effectively. All spray holes are directed towards the vehicle being washed, maximizing the washing force and achieving the best effect. The drainage collection ditch is located in the middle to effectively collect the washing wastewater, preventing secondary pollution, and centrally collecting it into a sedimentation tank, improving water resource utilization. This solution solves the problems of easy clogging of the spray pipes and nozzles and poor cleaning effect of the original car wash device, improving the car wash effect and efficiency.

[0009] Preferably, as an improvement, the drainage collection ditch is provided with a base with bearings on both sides, and the bottom nozzle is rotatably connected to the bearing in the base; one end of the bottom nozzle is provided with a drive mechanism, the output shaft of the drive mechanism is connected to one end of the bottom nozzle through a transmission belt, and the other end of the bottom nozzle is rotatably connected to the water supply pipe.

[0010] The two fixed bottom spray pipes have blind spots, and the bottom of the vehicle cannot be completely cleaned. Due to the limited space for installing pipes, it is not possible to add more pipes. In order to increase the cleaning area of ​​the bottom, it is considered to install a rotating bottom spray pipe. A drive mechanism is set at one end of the bottom spray pipe. The drive mechanism drives the bottom spray pipe to rotate through a transmission belt, realizing the dynamic adjustment of the spray hole coverage area, ensuring all-round cleaning without blind spots, and further improving the washing effect and water resource utilization.

[0011] Preferably, as an improvement, it also includes a grid cover plate, which is elongated and located between the two bottom nozzles and is detachably connected to the drainage collection ditch.

[0012] During the cleaning process, the grating cover effectively prevents large pieces of coal sludge and other debris from entering the drainage collection ditch, ensuring unobstructed drainage. It also facilitates regular cleaning and maintenance, further extending equipment lifespan and improving overall cleaning efficiency. The grating cover is lightweight, easy to disassemble and install manually, reducing maintenance difficulty and improving operational convenience. Its corrosion-resistant material adapts to harsh working environments, ensuring long-term stable use.

[0013] Preferably, as an improvement, an electric scraper is provided in the drainage collection ditch.

[0014] Due to the special properties of coal slime, some of it accumulates at the bottom of the drainage collection ditch, reducing drainage efficiency and even causing blockages. Therefore, electric scrapers are installed in the drainage collection ditch. The electric scrapers can scrape the slime at a certain frequency, effectively removing sediment in the ditch, ensuring smooth drainage, and improving flushing and drainage efficiency.

[0015] Preferably, as an improvement, the retaining wall is provided with two sensing devices, the drive mechanism is provided with a first controller, and the water supply pipe also includes an electric water valve and a second controller. The sensing devices are used to sense the entry and exit of vehicles and transmit signals to the first controller and the second controller. The first controller is used to receive signals and control the opening and closing of the drive mechanism, and the second controller is used to receive signals and control the opening and closing of the electric water valve.

[0016] Existing car wash systems require dedicated personnel or manual operation by the driver to open the water valves for vehicle washing, resulting in a waste of manpower and water resources. To improve automation and reduce this waste, a sensor is installed to transmit signals to the first controller to control the opening and closing of the drive mechanism, and to the second controller to control the opening and closing of the electric water valve. This ensures that vehicles are automatically sprayed with water when entering the car wash system, with the bottom spray nozzle rotating to clean them. When a vehicle leaves the system, the electric water valve and drive mechanism are automatically shut off, avoiding resource waste and improving automation and ease of operation.

[0017] Preferably, as an improvement, each vertical nozzle is equipped with an electric valve and a third controller, and sensors are installed on the side walls of the vertical nozzles. The sensors are used to detect the entry and exit of vehicles and transmit the signals to the third controller, which controls the opening and closing of the electric valves.

[0018] Based on the above solution, further research and improvement revealed that all the nozzles would operate simultaneously after the vehicle entered the cleaning device, resulting in ineffective spraying and wasting water resources. Therefore, electric valves and a third controller were installed on the vertical nozzles, and sensors were also installed on the side walls of the vertical nozzles. The electric valves matched the vehicle position according to the sensor signals and automatically controlled the start and stop of water spraying from a single vertical nozzle to avoid ineffective spraying, further improve water resource utilization and cleaning efficiency, and achieve intelligent management.

[0027] Example 1 is basically as shown in the attached document. Figure 1-5 As shown:

[0028] As attached Figure 1 As shown, a coal slurry washing device based on a coal truck includes a hardened base plate, a sedimentation tank and a water supply pipe, as well as a retaining wall 1, a spray pipe and a drainage collection ditch 8. The base plate of this device is generally elongated, and the retaining wall 1 is located on both sides of the base plate.

[0029] The bottom plate has an inverted trapezoidal cross-section to prevent sewage from flowing out of the device. Vibration strips 4 are symmetrically arranged on both sides of the bottom plate along its length, causing mud adhering to the vehicle to fall off through vibration, improving cleaning efficiency. The spray system includes two bottom spray pipes 3 and ten vertical spray pipes 2. The vertical spray pipes 2 are symmetrically and equally spaced on the side walls 1. Water spray holes are evenly spaced on the side walls of the vertical spray pipes 2, parallel to and away from the side walls 1, ensuring the shortest spray distance and optimal washing effect.

[0030] As attached Figure 2As shown, to increase the bottom coverage area for cleaning, four bearing-equipped bases are provided on both sides of the drainage collection ditch 8. The bottom spray pipe 3 is rotatably connected to the bearings of the bases. One end of the bottom spray pipe 3 is equipped with a drive mechanism 7. The output shaft of the drive mechanism 7 and the rotating shaft 702 at the left end of the bottom spray pipe 3 are connected by a transmission belt. The other end of the bottom spray pipe 3 is rotatably connected to the water supply pipe. Spray holes are evenly spaced on the side wall of the bottom spray pipe 3. The bottom spray pipe 3, installed in the bearings of the base, can rotate to perform water spray cleaning operations. The drive motor 701 of the drive mechanism 7 is a three-phase asynchronous motor, which can rotate forward and reverse. The drive mechanism 7 also includes a protective box to protect the drive mechanism 7 from contamination and damage. The drive mechanism 7 drives the bottom spray pipe 3 to rotate through the transmission belt, realizing dynamic adjustment of the spray hole coverage area, ensuring all-round cleaning without dead angles, and further improving the rinsing effect and water resource utilization rate.

[0031] Existing washing equipment requires dedicated personnel or manual operation by the driver to open the water valve for vehicle washing, resulting in a waste of manpower and water resources. To improve automation and reduce the waste of manpower and water resources, two sensing devices 6 are installed at both ends of the retaining wall 1. The two sensing devices 6 are linked together. The drive mechanism 7 is equipped with a first controller. The water supply pipe includes an electric water valve and a second controller. The sensing devices are used to detect the entry and exit of vehicles and transmit signals to the first and second controllers. The first controller is used to receive signals and control the opening and closing of the drive mechanism 7. The second controller is used to receive signals and control the opening and closing of the electric water valve to ensure that water is automatically sprayed when the vehicle enters the car wash device. When the second controller receives the signal from the sensing device 6, the drive mechanism 7 drives the bottom spray pipe to rotate and spray water for cleaning. When leaving the device, the electric water valve and drive mechanism 7 are automatically closed to avoid resource waste and improve the level of automation and ease of operation.

[0032] The drainage collection ditch 8 is located between the two bottom spray pipes 3. The upper part of the drainage collection ditch 8 is detachably connected to a long strip-shaped grid cover plate 5 to prevent large pieces of garbage, mud, and stones from entering the drainage collection ditch 8 and avoid clogging. After long-term use, silt will inevitably accumulate in the drainage collection ditch 8. In order to prevent clogging and facilitate cleaning, an electric scraper 801 is installed in the drainage collection ditch 8 to scrape the sludge at a set frequency. One end of the drainage collection ditch 8 is connected to a sedimentation tank.

[0033] By rationally arranging and combining the above components, the coal sludge washing device based on the coal truck in this embodiment is formed. It not only solves the problems of easy clogging of the nozzle and insufficient cleaning height leading to poor cleaning effect, thus improving the washing effect and efficiency, but also significantly reduces labor costs and improves work efficiency through the improvement of automation.

[0034] The specific implementation method is as follows:

[0035] As attached Figure 1 As shown, the vehicle to be cleaned enters from the right end of the device. After the sensor 6 detects the vehicle's entry, the first controller activates the drive mechanism, and the second controller activates the electric water valve. The vertical spray pipe 2 and the bottom spray pipe 3 then spray high-pressure water to begin cleaning the vehicle. (See attached diagram.) Figure 2 and attached Figure 3 As shown, the first controller controls the three-phase asynchronous motor to operate, causing the bottom nozzle 3 to rotate clockwise and counterclockwise within a certain angle, thoroughly cleaning the bottom area of ​​the vehicle. As the vehicle continues to move forward, it continues to vibrate in conjunction with the high-pressure water flow to complete the vehicle washing. When the sensor 6 detects that the rear of the vehicle has left the washing area, the drive mechanism 7 and the electric water valve close. Automatic water spraying and automatic water shut-off are achieved through the sensor 6, the first controller, and the electric water valve. The bottom nozzle 3 automatically rotates and stops operating through the sensor 6, the second controller, and the drive mechanism. The first and second controllers utilize existing PLC technology. Large pieces of garbage or coal sludge generated during vehicle washing are blocked by the grille cover 5. Other wastewater and coal sludge flow into the drainage collection ditch 8. The electric scraper 801 reciprocates at a regular frequency, pushing the sediment in the drainage collection ditch 8 into the sedimentation tank.

[0036] Example 2 is attached. Figure 6 As shown:

[0037] Unlike Embodiment 1, the vertical nozzle 2 is equipped with an electric valve 9 and a third controller. A sensor 10 is also installed on the retaining wall 1 to the right of the vertical nozzle. The sensor 10 detects vehicle entry and exit and transmits signals to the third controller, which then controls the opening and closing of the electric valve 9. Based on Embodiment 1, the addition of the sensor 10, the third controller, and the electric valve 9 further improves resource utilization efficiency and effectively reduces water waste.

[0038] The specific implementation method is as follows:

[0039] Unlike Embodiment 1, after the sensing device 6 detects that a vehicle has entered the washing area, the electric water valve of the water supply pipe opens, and the vehicle continues to move. Then, the sensor of the first vertical spray pipe 2 detects the vehicle, and the electric valve 9 of the vertical spray pipe 2 opens, spraying high-pressure water to start washing the vehicle. When the vehicle leaves the area where the first vertical spray pipe 2 is located, if the sensor 10 fails to detect the vehicle, the third controller controls the electric valve 9 of the vertical spray pipe to close, stopping the water spraying. This process is repeated to open or close subsequent electric valves 9 to complete the vehicle washing. When the sensing device 6 detects that the rear of the vehicle has left the car wash area, the electric water valve of the water supply pipe closes, completing the overall water shut-off operation. The system uses sensors and electric valves 9 to achieve water spraying when the vehicle arrives and water shut-off when the vehicle leaves. The other parts are the same as in Embodiment 1 and will not be described again here.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
