Description

Technical Field

[0001] This utility model relates to the technical field of plastic cleaning equipment, and specifically discloses a plastic cleaning device. Background Technology

[0002] Waste plastics refer to plastic products and scraps discarded during production, consumption, or use. Through sorting and recycling, waste plastics can be recycled into new products through processes such as crushing, washing, and melting. For example, recycled plastic granules can be used to make flower pots and trash cans, or they can be converted into raw materials through chemical depolymerization, reducing dependence on petroleum resources. Among these processes, the washing of waste plastics is usually completed by plastic washing equipment.

[0003] Chinese patent CN217752261U discloses a used plastic cleaning device, including a cleaning tank and a water tank. The water tank is installed on the top of the cleaning tank. A filter plate is provided in the inner cavity of the cleaning tank and below the stirring rod. A water pump is installed on the other side of the surface of the cleaning tank through a fixing plate. This utility model relates to the field of plastic cleaning technology. This waste plastic cleaning device, through the setting of a filter plate, can filter the water source after cleaning to remove impurities mixed in the water source. Furthermore, through the setting of a water pump, a three-way pipe, a first water intake pipe, a second water intake pipe, a first water guide pipe, and a second water guide pipe, the cleaned water source can be recycled, achieving the purpose of reuse. This significantly reduces the water consumption required for cleaning plastics, reduces cleaning costs, and thus improves the energy efficiency of the equipment. Simultaneously, the setting of an electric heating plate can dry the cleaned plastics, thereby improving the functionality of the equipment. However, during the use of the above device, when the plastic comes into contact with the filter plate, the sediment attached to the filter plate is easily scraped off and comes into contact with other plastics, affecting the quality and efficiency of cleaning. Therefore, in order to solve the above problems, this utility model proposes a plastic cleaning device. Utility Model Content

[0004] The present invention aims to provide a plastic cleaning device that can prevent the plastic from scraping off the sediment on the filter plate, thereby ensuring the quality and efficiency of plastic cleaning.

[0005] This utility model is achieved through the following technical solution:

[0006] A plastic cleaning device includes a cleaning mechanism comprising a cleaning tank, an inner side of which is provided with a stirring rod, the upper end of which is connected to a motor, a first drain pipe at the lower center of the cleaning tank, a second drain pipe on one side of the first drain pipe, a top plate connected to the top of the cleaning tank, a first support on the outer side of the cleaning tank, and a filtering mechanism on one side of the lower end of the cleaning tank. The filtering mechanism includes a water tank, with multiple mounting plates arranged in a linear array on both sides of the inner wall of the water tank, a filter plate detachably connected above the mounting plates, a connecting pipe connected to the top of the water tank, a first water injection pipe connected to the lower end of one side of the water tank, a water pump connected to the upper end of the first water injection pipe, and a second water injection pipe connected above the water pump.

[0007] As a further feature of the above solution, a discharge port is provided on one side of the cleaning tank, and multiple connecting shafts arranged in a linear array are provided on both sides of the discharge port. A sealing plate is provided on the inner side of the discharge port, and a rubber ring is provided on the outer side of the sealing plate. One side of the rubber ring is pressed against the inlet to block the discharge port and prevent water in the cleaning tank from leaking out from the gap between the sealing plate and the discharge port during the cleaning process. The sealing plate and the connecting shafts are detachably connected for easy disassembly and assembly.

[0008] As a further feature of the above solution, a protective cover is provided on the inner side of the discharge port to separate the hot air blower from the plastic. A rubber ring is provided on the outer side of the protective cover. The hot air blower is connected to the side of the protective cover away from the cleaning box, which can inject high-temperature airflow into the cleaning box to dry the plastic inside the cleaning box. The protective cover and the connecting shaft are detachably connected, making it convenient to disassemble and assemble the protective cover and the hot air blower.

[0009] As a further feature of the above solution, one end of the first drain pipe and the second drain pipe are respectively connected to a first valve and a second valve, which allows the user to control the opening and closing of the two drain pipes. The stirring rod passes through the middle of the top plate and is rotatably connected to the top plate, which enables the top plate to provide support for the stirring rod. The top plate is provided with a feed inlet and a first water inlet pipe on both sides above it. A second water inlet pipe is provided on one side of the first water inlet pipe, which facilitates the injection of clean water and filtered water into the cleaning tank.

[0010] As a further feature of the above solution, the first water inlet pipe is connected to the second water injection pipe to facilitate the injection of filtered water into the cleaning tank. A pressure plate is provided above the feed inlet, and a telescopic rod is connected to the upper middle part of the pressure plate. The telescopic rod can be extended during the plastic drying process. The feed inlet is blocked by the pressure plate, leaving only the second water inlet pipe as an air outlet to reduce heat loss. A second bracket is connected to the outside of the telescopic rod, and the motor is connected to the second bracket. The lower end of the second bracket is connected to the top plate to provide support for the telescopic rod and the motor.

[0011] As a further feature of the above solution, the other end of the connecting pipe is connected to the first drain pipe to facilitate the discharge of the cleaned wastewater into the water tank. A third water inlet pipe is provided on one side of the upper part of the water tank. The water pump is detachably connected to the top of the water tank, which enables the water tank to provide support for the water pump and facilitates the installation and maintenance of the water pump.

[0012] As a further feature of the above solution, a controller is provided on one side of the first bracket, and the telescopic rod, motor and water pump are all connected to the controller via power lines and signal lines.

[0013] The present invention has the following beneficial effects during use:

[0014] The combined use of the feed inlet, pressure plate, and telescopic rod in the cleaning mechanism allows the telescopic rod to retract before cleaning, separating the pressure plate from the feed inlet and keeping the feed inlet open. During the drying process after cleaning, the telescopic rod is extended, and the pressure plate is used to block the feed inlet, leaving only the second water inlet pipe as the air outlet. This maintains the air pressure balance inside and outside the cleaning chamber while reducing heat loss.

[0015] The separate design of the water tank and the cleaning tank can prevent the plastic from bringing the sediment on the filter plate back into the cleaning water due to contact with the filter plate, and prevent the impurities from re-adhering to the plastic during the plastic drying process, thus ensuring the quality of plastic cleaning.

[0034] like Figure 1 and Figure 2 As shown, a controller 3 is provided on one side of the first bracket 117, and the telescopic rod 17, motor 19 and water pump 25 are all connected to the controller 3 through power lines and signal lines.

[0035] The plastic cleaning device disclosed in this embodiment involves placing a sufficient amount of plastic to be cleaned into the cleaning tank 11 through the inlet 151 before use. The existing water pipe is connected to the second inlet pipe 153, and sufficient clean water is injected into the cleaning tank 11. The controller 3 is used to start the motor 19, causing the motor 19 to drive the stirring rod 18 to rotate, agitating the plastic and water in the cleaning tank 11 to clean the plastic. Alternatively, the plastic can be soaked for a period of time before starting the motor 19 to drive the stirring rod 18 to agitate it. After cleaning, the first valve 114 is opened to discharge the wastewater in the cleaning tank 11 into the water tank 21 through the first drain pipe 113 and the connecting pipe 23. The wastewater, filtered by the multi-layer filter plates 22 from top to bottom in the water tank 21, is stored in the cavity at the bottom of the lowest filter plate 22 and the inner side of the water tank 21. The sealing plate 12 is removed to check the cleaning condition of the plastic inside the cleaning tank 11. If repeated cleaning is required, the connection between the sealing plate 12 and the connecting shaft 112 is restored, and the controller 3 is used to start the water pump. 25. The water pump 25 injects the filtered water in the cavity into the cleaning tank 11 through the first water injection pipe 24, the second water injection pipe 26 and the first water inlet pipe 152. The motor 19 drives the stirring rod 18 to rotate and clean the plastic.

After the filtered water in the water tank 21 is injected into the cleaning tank 11 through the first water injection pipe 24, the second water injection pipe 26, the water pump 25 and the second water inlet pipe 153, the sewage stored in the original water storage device is injected into the water tank 21 through the third water inlet pipe 212 and stored in the cavity after being filtered by the filter plate 22.

[0036] After cleaning, drain the water from the cleaning tank 11, remove the sealing plate 12, use the controller 3 to control the extension rod 17 to extend, push the pressure plate 16 towards the feed inlet 151, so that the pressure plate 16 blocks the feed inlet 151, connect the protective cover 13 to the connecting shaft 112, connect the power cord of the hot air blower 14 to the external power supply, start the hot air blower 14, so that the hot air blower 14 injects high-temperature airflow into the cleaning tank 11 to dry the plastic inside the cleaning tank 11. During the drying process, the motor 19 drives the stirring rod 18 to rotate, so that the plastic is fully in contact with the high-temperature airflow and dried evenly. The high-temperature steam is discharged from the cleaning tank 11 through the second drain pipe 115. After drying, disconnect the power cord of the hot air blower 14 from the external power supply, separate the protective cover 13 from the connecting shaft 112, and take the plastic out from the discharge port 111.
