Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicle cleaning. Background Art
[0002] Concrete trucks, also known as mixer trucks, are specialized trucks used to transport ready-mixed concrete for construction. According to the "Technical Regulations for Green Production and Management of Ready-Mixed Concrete" (JGJ / T328-2014), production wastewater and waste concrete must not be directly discharged outside the factory boundaries during green production. During green production, a truck cleaning device should be designed to automatically clean the trucks, ensuring a clean appearance when entering and leaving the factory. Flushing water can be tap water or settled production wastewater. If there is oil on the surface of the mixer truck, the oil should be removed first to prevent oil, oxalic acid, and detergents from entering the flushing wastewater. The flushing wastewater should be recycled into the production wastewater treatment system. Concrete mixer trucks need to be cleaned before leaving the mixing station to ensure the cleanliness of the vehicle, reduce environmental pollution, and extend the vehicle's service life.
[0003] Existing cleaning equipment uses nozzles to spray and clean the surface of transport vehicles. This has a small spray area and requires workers to use handheld nozzles for additional cleaning, which increases the workload and labor costs of vehicle cleaning. Furthermore, when vehicles are transported on the road after being spray-cleaned, dust from the outside easily adheres to the wet vehicle body, causing further contamination and reducing the cleanliness of the vehicle. Utility Model Content
[0004] The purpose of the utility model is to solve the above technical problems and provide an automatic cleaning device for a concrete transport vehicle.
[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:
[0006] An automatic cleaning device for a concrete transport vehicle comprises a wastewater pool and a purification pool connected in sequence, a cleaning area being distributed on the wastewater pool, a washing platform being provided on the cleaning area, the washing platform being in the shape of a porous grid, spray columns being provided on both sides of the washing platform, a plurality of nozzles being distributed along the vertical direction on the spray columns, a vehicle crushing switch being provided at the inlet and outlet ends of the cleaning area, a sewage purification unit being provided in the purification pool, and a delivery pump being provided, the delivery pump being connected to the nozzles through a pipeline, a washing liquid tank being provided in the purification pool, an electromagnetic three-way valve being provided at the liquid inlet end of the delivery pump, respectively connecting the washing liquid tank and the output end of the sewage purification unit, a drying component being provided at the output end of the cleaning area, and a PLC controller being provided, the vehicle crushing switch and the delivery pump being electrically connected to the PLC controller.
[0007] Through the above scheme, after the mixing vehicle enters the cleaning area, it rolls over the vehicle rolling switch, and the signal is transmitted to the PLC controller. The PLC controller controls the delivery pump to start, and the electromagnetic three-way valve is connected to the output end of the sewage purification unit of the purification pool and the washing liquid tank in sequence. The cleaning water and washing liquid are sprayed through the nozzle to clean the mud and sand stains around the vehicle. Then the vehicle surface is quickly dried by the drying component. After washing with washing liquid, a smooth coating is formed on the periphery of the vehicle, which further reduces the adhesion of external dust and debris to the vehicle body. After cleaning and drying, the vehicle drives away and touches the vehicle rolling switch again. The signal is transmitted to the PLC controller. The PLC controller controls the delivery pump, the electromagnetic three-way valve and the drying component to close. The whole process does not require personnel to assist in cleaning, has a high degree of automation, cleans, saves labor, and improves cleaning efficiency.
[0008] Furthermore, the drying component includes a drying fan symmetrically arranged at the end of the cleaning area, an electric heating wire is provided at the air inlet of the drying fan, and the drying fan is electrically connected to the PLC controller.
[0009] Through the above solution, a drying fan is provided in conjunction with an electric heating wire to blow out hot air, thereby conveniently and quickly drying the vehicle body.
[0010] Furthermore, the drying fan is provided with a plurality of air outlets, the air outlets are arranged vertically, and the arrangement height of the air outlets is not less than the height of the vehicle.
[0011] Through the above solution, multiple air outlets are set, and the air outlet arrangement height is set to be no less than the vehicle height, so that the entire vehicle body can be dried quickly and conveniently with a wide coverage area.
[0012] Furthermore, a spoiler impeller is installed at the air outlet.
[0013] Through the above solution, the impeller is provided to facilitate the turbulence of the hot air and expand the blowing area.
[0014] Furthermore, a float is provided at the bottom end of the washing table, and guard plates extending toward the wastewater pool are hinged at both ends of the washing table. The guard plates are overlapped on the wastewater pool, and the float is provided around the washing table. An overflow port leading to the purification pool is provided at the upper end of the wastewater pool, and a support platform is provided under the washing table, and the height of the support platform is lower than the height of the overflow port.
[0015] Through the above scheme, a float is set to float the washing table on the surface of the wastewater pool, which is convenient for the initial sedimentation of the wastewater pool after washing. When the vehicle enters the washing table along the guard plate, the float is pressed into the wastewater pool, and the washing table is supported by the support body to maintain the level. At this time, the liquid level in the wastewater pool rises, prompting the upper clear liquid of the wastewater pool to enter the overflow port and enter the purification tank for further purification. In fact, each time the car is washed, a part of the upper clear liquid of the wastewater pool will be squeezed into the purification tank along the overflow port, and impurities such as slag will be initially settled.
[0016] Furthermore, the output end of the sewage purification unit includes a sedimentation tank, a multi-stage primary filtration tank, an aeration tank, and a clear liquid tank, which are sequentially connected to each other in the purification tank. The overflow port leads to the sedimentation tank. An overflow port is also provided between the sedimentation tank and the multi-stage primary filtration tank. The multi-stage primary filtration tank is composed of several filter plates. An aeration pipe connected to a compressed air source is provided in the aeration tank. A froth tank is provided on one side of the aeration tank. A float ring is provided in the aeration tank. The float ring leads to the froth tank through a pipeline. The clear liquid tank is connected to a delivery pump through a pipeline.
[0017] Through the above scheme, the upper clear liquid of the wastewater pool is squeezed into the sedimentation tank along the overflow port for secondary sedimentation. The clear liquid at the upper end of the sedimentation tank then enters the multi-stage primary filtration tank along the overflow port, completes multi-stage filtration through several filter plates, and then enters the aeration tank for aeration and slag removal. The foam and slag in the aeration tank are collected in the foam tank along the float ring pipe. After the sewage is further purified, it enters the clear liquid tank for subsequent use.
[0018] Furthermore, the froth tank and the float ring are provided in two groups and are symmetrically distributed on both sides of the aeration tank.
[0019] Through the above scheme, the symmetrically arranged float ring and froth groove can increase the scum collection range and improve the scum village coarseness.
[0020] Furthermore, drainage troughs are distributed around the wastewater pool, and the drainage troughs are connected to the wastewater pool through pipes.
[0021] Through the above solution, a drainage trough is set up. When the vehicle completes cleaning and leaves, the dripping sewage flows into the sewage pool along the drainage trough, which is conducive to keeping the site clean.
[0022] The beneficial effects of the utility model are as follows:
[0023] 1. The utility model has a simple structure. After the mixing vehicle enters the cleaning area, it rolls over the vehicle rolling switch, and the signal is transmitted to the PLC controller. The PLC controller controls the delivery pump to start. At the same time, the electromagnetic three-way valve is connected to the output end of the sewage purification unit of the purification pool and the washing liquid tank in sequence. The cleaning water and washing liquid are sprayed through the nozzle to clean the mud and sand stains on the periphery of the vehicle. Then the vehicle surface is quickly dried by the drying component. After washing with washing liquid, a smooth coating is formed on the periphery of the vehicle, which further reduces the adhesion of external dust and debris to the vehicle body. After cleaning and drying, the vehicle drives away and touches the vehicle rolling switch again. The signal is transmitted to the PLC controller. The PLC controller controls the delivery pump, the electromagnetic three-way valve and the drying component to close. The whole process does not require personnel to assist in cleaning. The degree of automation is high, the cleaning is clean, labor is saved, and the cleaning efficiency is improved.
[0024] 2. A float is set up to float the washing table on the surface of the wastewater pool, which is convenient for the initial sedimentation of the wastewater pool after washing. When the vehicle enters the washing table along the guard plate, the float is pressed into the wastewater pool, and the washing table is supported by the support body to maintain the level. At this time, the liquid level in the wastewater pool rises, prompting the upper clear liquid of the wastewater pool to enter the overflow port and enter the purification tank for further purification. In fact, each time the car is washed, a part of the upper clear liquid of the wastewater pool will be squeezed into the purification tank along the overflow port, and impurities such as slag will be initially settled.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.
[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.
[0032] Example 1
[0033] like Figure 1 and Figure 2 and Figure 3 As shown, this embodiment provides an automatic cleaning device for a concrete transport vehicle, comprising a wastewater tank 11 and a purification tank 12 connected in sequence. The wastewater tank 11 and the purification tank 12 are arranged at the entrance and exit of the mixing station to facilitate cleaning of the vehicle. A cleaning area 13 is distributed on the wastewater tank 11. The cleaning area 13 is used to clean the vehicle and collect wastewater. A washing platform 14 is provided on the washing area 13. The washing platform 14 is in a porous grid shape. Spray columns 15 are provided on both sides of the washing platform 14. The spray columns 15 are distributed with a number of nozzles 16 in the vertical direction. The cleaning area 13 is provided with a vehicle crushing switch 17 at the entrance and exit ends. The sewage purification unit is further provided with a delivery pump 18, which is connected to the nozzle 16 through a pipeline. A washing liquid tank 19 is provided in the purification pool 12. An electromagnetic three-way valve 36 is provided at the liquid inlet end of the delivery pump 18, which is respectively connected to the washing liquid tank 19 and the output end of the sewage purification unit. A drying component is provided at the output end of the cleaning area 13. The drying component includes a drying fan 20 symmetrically arranged at the end of the cleaning area 13. A heating wire 21 is provided at the air inlet of the drying fan 20. The drying fan 20 is electrically connected to the PLC controller. A PLC controller is also provided. The vehicle crushing switch 17 and the delivery pump 18 are both electrically connected to the PLC controller.
[0034] Therefore, after the mixing vehicle enters the washing area 13, it rolls over the vehicle rolling switch 17, and the signal is transmitted to the PLC controller. The PLC controller controls the delivery pump 18 to start and the electromagnetic three-way valve 36 to connect to the output end of the sewage purification unit of the purification tank 12 to perform preliminary cleaning of the vehicle periphery. Then, the electromagnetic three-way valve 36 is controlled to pass into the washing liquid tank 19, and the washing liquid is sprayed to remove the debris around the vehicle. Finally, it continues to connect to the purification tank 12, and the washing water and washing liquid are sprayed through the nozzle 16 to clean the mud and sand stains around the vehicle. Then, the vehicle surface is quickly dried by the drying component. By setting a drying fan 20 and an electric heating wire 21 to blow out hot air, it is convenient to quickly dry the vehicle body. After the washing and drying with washing liquid, a smooth coating is formed on the vehicle periphery, further reducing the adhesion of external dust and debris to the vehicle body. After cleaning and drying, the vehicle leaves and touches the vehicle rolling switch 17 again. The signal is transmitted to the PLC controller. The PLC controller controls the delivery pump 18, the electromagnetic three-way valve 36 and the drying component to close. The whole process does not require human assistance for cleaning, has a high degree of automation, cleans thoroughly, saves labor, and improves cleaning efficiency.
[0035] To further improve the drying effect, refer to Figure 1 and Figure 2The drying fan 20 is provided with a plurality of air outlets 22. The air outlets 22 are generally arc-shaped and arranged vertically. The air outlets 22 are arranged at a height not less than the height of the vehicle. The air outlets 22 are equipped with spoiler impellers 23. The spoiler impellers 23 are evenly distributed at the air outlets 22. The provision of multiple air outlets 22 and the arrangement of the air outlets 22 at a height not less than the height of the vehicle facilitate rapid drying of the entire vehicle body and wide coverage. The provision of the impeller facilitates spoiling of the hot air and expands the blowing area.
[0036] Reference Figure 1 A drainage trough 24 is distributed on the periphery of the wastewater pool 11. The drainage trough 24 surrounds the wastewater pool 11 and is connected to the wastewater pool 11. The drainage trough 24 is set at a slope. The drainage trough 24 is connected to the wastewater pool 11 through a pipe. The drainage trough 24 is set. When the vehicle completes cleaning and leaves, the dripping sewage enters the sewage pool along the drainage trough 24, which is conducive to keeping the site clean.
[0037] Reference Figure 1 and Figure 3 , a buoy 25 is provided at the bottom of the washing table 14, and there are four buoys 25 evenly distributed around the washing table 14. The two ends of the washing table 14 are hinged with guard plates 26 extending to the wastewater tank 11. The guard plates 26 are overlapped on the wastewater tank 11. The buoys 25 are provided around the washing table 14. The upper end of the wastewater tank 11 is provided with an overflow port 27 leading to the purification tank 12. A support platform 28 is provided under the washing table 14. The height of the support platform 28 is lower than the height of the overflow port 27. The buoys 25 are provided to float the washing table 14 on the wastewater tank 11. The surface of the water pool 11 is convenient for the initial sedimentation of the wastewater pool 11 after washing. When the vehicle enters the washing platform 14 along the guard plate 26, the float 25 is pressed into the wastewater pool 11, and the washing platform 14 is supported by the support body to maintain the level. At this time, the liquid level in the wastewater pool 11 rises, prompting the upper clear liquid of the wastewater pool 11 to enter the overflow port 27 and enter the purification tank 12 for further purification. In fact, each time the car is washed, a part of the upper clear liquid of the wastewater pool 11 will be squeezed into the purification tank 12 along the overflow port 27 to initially settle the slag and other impurities.
[0038] Reference Figure 1 and Figure 2 and Figure 3In order to improve the sewage treatment effect, the output end of the sewage purification unit includes a sedimentation tank 29, a multi-stage primary filter tank 30, an aeration tank 31, and a clear liquid tank 32, which are sequentially connected in the purification tank 12. The overflow port 27 leads to the sedimentation tank 29. An overflow port 27 is also provided between the sedimentation tank 29 and the multi-stage primary filter tank 30. The multi-stage primary filter tank 30 is composed of a plurality of filter plates. An aeration pipe 33 connected to a compressed air source is provided in the aeration tank 31. A froth tank 34 is provided on one side of the aeration tank 31. A float ring 35 is provided in the aeration tank 31. The float ring 35 is connected to the froth tank 34 through a pipeline. The clear liquid tank 32 is connected to the delivery pump 18 through a pipeline. The upper clear liquid of the wastewater tank 11 flows along the overflow port 27 into the sedimentation tank 29 for secondary sedimentation. The clear liquid at the upper end of the sedimentation tank 29 then flows along the overflow port 27 into the multi-stage primary filtration tank 30, completes multi-stage filtration through a number of filter plates, and then enters the aeration tank 31 for aeration and slag removal. The foam and slag in the aeration tank 31 are collected in the foam tank 34 along the flotation ring 35 pipeline. After the sewage is further purified, it enters the clear liquid tank 32 for subsequent utilization.
[0039] Reference Figure 1 There are two groups of froth troughs 34 and float rings 35, which are symmetrically distributed on both sides of the aeration tank 31. The symmetrically arranged float rings 35 and froth troughs 34 are convenient for increasing the scum collection range and improving the scum storage capacity.
[0040] Implementation principle: After the mixing vehicle enters the cleaning area 13, it rolls over the vehicle rolling switch 17, and the signal is transmitted to the PLC controller. The PLC controller controls the delivery pump 18 to start, and at the same time, the electromagnetic three-way valve 36 is connected in sequence to the output end of the sewage purification unit of the purification tank 12 and the washing liquid tank 19. The cleaning water and washing liquid are sprayed through the nozzle 16 to clean the mud and sand stains around the vehicle. Then the vehicle surface is quickly dried by the drying component. After washing with washing liquid, a smooth coating is formed on the periphery of the vehicle, which further reduces the adhesion of external dust and debris to the vehicle body. After cleaning and drying, the vehicle drives away and touches the vehicle rolling switch 17 again. The signal is transmitted to the PLC controller. The PLC controller controls the delivery pump 18, the electromagnetic three-way valve 36 and the drying component to close. The whole process does not require personnel to assist in cleaning, has a high degree of automation, cleans, saves labor, and improves cleaning efficiency.
