Description

TECHNICAL FIELD

[0001] The utility model relates to car washing equipment technical field, concretely relates to a sewage recycling treatment and reuse water -saving car washing equipment. BACKGROUND

[0002] In modern society, cars have become an indispensable means of transport in people's life, and the car washing demand is also growing. The traditional car washing equipment and mode are faced with a series of problems to be solved.

[0003] On the one hand, the traditional car washing equipment consumes a large amount of fresh water resources in the car washing process. Usually, the car washing water is used only once in a single car washing process and is discharged, and the water resources are not effectively recycled and utilized. On the other hand, if the sewage generated by car washing is not effectively treated and directly discharged, it will cause certain pollution to the environment. The sewage from car washing contains pollutants such as silt, oil stains and detergents. If these pollutants are directly discharged into the municipal sewage pipe network or the surrounding soil and water environment, they may affect the normal operation of the municipal sewage treatment system and may also damage the soil and water ecological environment, such as causing soil compaction and water eutrophication.

[0004] Some existing car washing equipment does not have a perfect sewage recycling treatment and reuse system when in use, which means that a large amount of car washing water is directly discharged after being used once, cannot be effectively recycled and utilized, and causes great waste of water resources. UTILITY MODEL CONTENTS

[0006] The technical scheme of the utility model is: a sewage recycling treatment and reuse water -saving car washing equipment, which comprises a car washing unit, a sewage collection and purification unit and a recycling pipe.

[0007] The car washing unit comprises a filtrate pool, a car washing platform arranged at the upper end of the filtrate pool, a filter plate arranged at the upper end of the car washing platform, and a high-pressure water gun arranged at the side edge of the car washing platform.

[0008] The sewage collection and purification unit comprises a sewage collection pool connected with the filtrate pool and provided with a first water pump at the connection, a filter screen plate arranged at the water outlet of the filtrate pool, a reagent adding port arranged in the sewage collection pool, and a disinfection pool connected with the upper end of the sewage collection pool.

[0009] The recycling pipe is used for connecting the disinfection pool and the high-pressure water gun, and a second water pump is arranged at the connection.

[0010] Further, the upper end of the filtrate tank is provided with a cleaning unit, the cleaning unit comprises sliding grooves arranged on the front and back sides of the filtrate tank, sliding blocks corresponding to the two sliding grooves in sliding connection, a cleaning scraper for connecting the two sliding blocks, and hydraulic cylinders for connecting the sliding blocks and the sliding grooves.

[0011] Description: When the car is cleaned on the filter plate, the sewage after cleaning falls into the filtrate tank for collection. When the upper end of the filter plate needs to be cleaned, the corresponding sliding block is driven by the hydraulic cylinder to slide in the sliding groove, and the upper end of the filter plate is scraped and cleaned by the cleaning scraper. The automatic operation of the filter plate cleaning can prevent clogging and excessive wear, and prolong the service life of the filter plate.

[0012] Further, one side of the filtrate tank is provided with a sundry collecting groove for collecting sundries on the upper end of the filter plate, and a sewage discharge valve is connected between the filtrate tank and the sundry collecting groove.

[0013] Description: After the dirt or impurities on the upper end of the filter plate are pushed and scraped by the cleaning scraper, they fall into the sundry collecting groove, which facilitates subsequent classification, treatment or transfer, and improves the overall processing efficiency. When the sediment at the bottom end of the filtrate tank needs to be cleaned, open the sewage discharge valve and drop into the sundry collecting groove for collection, which can quickly empty the filtrate tank, reduce the time required for manual cleaning, and the concentrated sediment is easy to manage and transport, which can be more orderly processed and disposed, reducing environmental risks.

[0014] Further, the reagent adding port is connected with a bulk material disc at the bottom end, a plurality of bulk material holes are uniformly arranged at the bottom end of the bulk material disc, and a sewage discharge port is arranged at the bottom end of the sewage collecting tank.

[0015] Description: When the flocculating agent is added to the sewage collecting tank, it is added into the bulk material disc through the reagent adding port, and is uniformly sprayed into the car washing water body in the sewage collecting tank through each bulk material hole, which helps the flocculating agent to fully contact with the suspended solids and impurities in the car washing water body, thereby improving the efficiency of the flocculation reaction.

[0016] Further, a water quality detector is arranged at the disinfection tank, and a circulating backflow pipe is connected between the disinfection tank and the sewage collecting tank.

[0017] Description: The water body clear liquid treated by flocculation and sedimentation in the sewage collecting tank is subjected to disinfection treatment in the disinfection tank, and the water quality is detected by the water quality detector after the treatment is completed, so that the effluent water meets the use standard. When the water quality does not meet the standard, the water is backflowed to the sewage collecting tank through the circulating backflow pipe for repeated treatment, and the whole process forms a closed treatment system, which can strictly guarantee the quality of the effluent water.

[0018] The beneficial effects of the utility model are as follows:
