Description

Technical Field

[0001] This utility model relates to the field of recycling bin technology, specifically a corrosion-resistant and environmentally friendly wastewater recycling bin. Background Technology

[0002] Industrial production, laboratory operations, and environmental treatment often generate large quantities of wastewater containing solid impurities, corrosive chemicals, and potentially volatile harmful gases. Effective collection, temporary storage, and pretreatment of this wastewater are crucial for ensuring operational safety and meeting environmental emission standards.

[0003] An existing patent (authorization announcement number: CN222411106U) discloses a wastewater recycling device for a pure water machine. The key technical points of the solution are: by providing a wastewater storage tank, the wastewater from the pure water machine can be recycled and stored; by providing a heating device, a guiding tank, an outlet tank, a liquid guiding tank, and a liquid outlet, the wastewater from the pure water machine can be treated, thereby recycling the wastewater and reducing waste of pure water machine wastewater, improving the utilization rate of pure water machine wastewater and reducing water resource waste; by providing a sealing ball and an elastic rope, the inlet of the pure water machine can be sealed when the wastewater is not introduced from the inlet, thereby reducing the leakage of water vapor from the inlet and reducing the entry of external impurities into the wastewater storage tank from the inlet, thus reducing the contamination of the wastewater storage tank.

[0004] However, the above technical solutions still have certain drawbacks. When wastewater is about to overflow, it needs to be transferred from a main tank to an auxiliary tank for graded temporary storage. Existing equipment mostly relies on manual observation of the liquid level and manual operation of valves, which is inefficient and increases the risk of personnel coming into contact with wastewater, and there is a risk of wastewater overflowing from the main tank. Therefore, a corrosion-resistant and environmentally friendly wastewater recycling tank is proposed. Utility Model Content

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] In one embodiment, such as Figures 1-7 As shown, a corrosion-resistant environmentally friendly wastewater recycling tank includes a main tank 1, with a secondary tank 2 connected to the side of the main tank 1. The bottom of the main tank 1 is also equipped with casters 3 with a self-locking function. The top of the main tank 1 is equipped with a filter assembly 5 for filtering wastewater. The center of the top of the main tank 1 is also equipped with a gas collection assembly 6 for collecting waste gas. The main tank 1 is also equipped with a stirring assembly 7 for stirring wastewater. A buoyancy-type opening and closing assembly 8 is provided between the main tank 1 and the secondary tank 2, which automatically opens and closes based on the liquid level in the main tank 1.

[0034] In this embodiment, industrial wastewater containing solid impurities and harmful gases is first poured in from the top. The filter component 5 intercepts solid particles, achieving preliminary solid-liquid separation. The pretreated wastewater enters the main tank 1. The wastewater entering the main tank 1 is stirred by the stirring component 7 to prevent suspended solids from settling. Harmful gases volatilized during the wastewater treatment process are actively collected by the gas collection component 6 at the top. When the liquid level in the main tank 1 rises to a certain height, the opening and closing component 8 automatically opens the connecting pipe 84 between the main tank 1 and the auxiliary tank 2, safely diverting excess wastewater to the auxiliary tank 2 and preventing the main tank 1 from overflowing. The universal wheels 3 with self-locking function at the bottom of the tank allow this recycling bin to be moved to the location where work needs to be done, and the self-locking function keeps it stable during the treatment process, preventing accidental slippage.

[0035] In one embodiment, such as Figure 2As shown, the filter assembly 5 includes a cover plate 51 fixedly installed on the top of the main tank 1. The top of the cover plate 51 is open, and an inlet pipe 52 is fixedly installed at the opening. A fixing ring 53 is fixedly installed at the bottom of the inlet pipe 52. A filter basket 54 is engaged at the top of the fixing ring 53. A handle 55 is fixedly installed at the top center of the filter basket 54. Filter holes are opened on the sides and bottom of the filter basket 54. Wastewater containing solid impurities is poured in through the inlet pipe 52. The wastewater first enters the filter basket 54. Liquid and fine dissolved substances will pass smoothly through the holes on the sides and bottom of the filter basket 54 and flow into the main tank 1 below. Solid impurities larger than the filter holes are trapped in the filter basket 54. When the solid impurities accumulated in the filter basket 54 reach a certain amount, the operator only needs to lift the entire filter basket 54 upwards using the handle 55 to remove it from the fixing ring 53. The filter residue can be easily poured out and cleaned, and then put back for continued use. It is simple and easy to operate.

[0036] In one embodiment, such as Figure 5 As shown, the stirring assembly 7 includes a drive motor 71 fixedly installed on the outer wall of the main tank 1. The drive motor 71 drives a stirring shaft 72. Multiple sets of stirring blades 73 are provided on the lever 81. The bottom of the main tank 1 is constructed as an inclined surface facing one side, and a liquid outlet 4 with a valve is connected to the side wall at its lowest point. The inner walls of both the main tank 1 and the auxiliary tank 2 are coated with an anti-corrosion coating. The multiple sets of stirring blades 73 installed on the stirring shaft 72 rotate with the shaft to stir the wastewater in the tank, preventing suspended solids in the wastewater from accumulating at the bottom. When the main tank 1 needs to be emptied, the valve on the liquid outlet 4 is opened. Under the action of gravity, all liquid and suspended solids will naturally flow to and concentrate at the liquid outlet 4 at the lowest point, thereby being completely discharged. The anti-corrosion coating on the inner wall of the main tank 1, such as polyurethane, prevents corrosive substances such as acids, alkalis, and salts in the wastewater from directly contacting and corroding the tank material.

[0037] In one embodiment, such as Figure 4As shown, the gas collection assembly 6 includes a gas collection box 61 fixedly installed on the cover plate 51. A baffle 62 is detachably provided on one side of the gas collection box 61. The baffle 62 and the gas collection box 61 are sealed together by a plug. The cover plate 51 is provided with a vent pipe that connects the inside of the main tank 1 with the inside of the gas collection box 61. A first filter plate 63, a second filter plate 64, and a third filter plate 64 are arranged sequentially along the gas flow direction inside the gas collection box 61. An exhaust valve 66 is also provided on the side wall of the gas collection box 61. The first filter plate 63 is filled with activated carbon, the second filter plate 64 is filled with soda lime, and the third filter plate 64 is filled with... Acidic neutralizing agent; when wastewater is left to stand or is being treated in the main tank 1, harmful gases are released and enter the upper gas collection box 61 through the vent pipe. First, the gas passes through the first filter plate 63, activated carbon, which mainly performs physical adsorption, effectively adsorbing organic pollutants, odor molecules, and some smoke particles in the waste gas. Then, it passes through the second filter plate 64, soda lime, which undergoes a chemical reaction to neutralize the acidic gases in the waste gas. Finally, it passes through the third filter plate 64, an acidic neutralizing agent, which is used to neutralize the alkaline gases in the waste gas. The waste gas undergoes three-stage purification. Afterward, the gas is discharged through the exhaust valve and can be removed at any time through the detachable baffle 62 and sealing plug for replacing the internal filter plates.

[0038] In one embodiment, such as Figure 6 As shown, the opening and closing assembly 8 includes a connecting pipe 84 disposed between the main tank 1 and the auxiliary tank 2, and a lever 81. The middle part of the lever 81 is rotatably disposed on the side wall of the main tank 1 via a rotating shaft. A float 82 is fixedly connected to one end of the lever 81 located inside the main tank 1. An abutment rod 83 is fixedly disposed at the end of the lever 81 away from the float 82. A rotatable first valve plug 85 is disposed inside the connecting pipe 84. A second valve plug 87 is fixedly connected to the first valve plug 85 via a connecting rod 86. An abutment block 88 is also disposed inside the connecting pipe 84 to abut against the first valve plug 85. When the liquid level in the main tank 1 is low, the float 82 sinks due to its own weight and the weight of the other end of the lever 81. The end of the lever 81 away from the float 82 (right side) is lifted upward, and the abutment rod 83 fixed at that end is also lifted. At this time, the abutment rod 83 no longer applies downward pressure to the second valve plug 87. The first valve plug 85 inside the connecting pipe 84, under its own weight or water pressure, presses tightly against the abutment block 88, blocking the passage of the connecting pipe 84. With the connecting pipe 84 closed, wastewater from the main tank 1 will not flow into the auxiliary tank 2. As wastewater is continuously added to the main tank 1, the liquid level gradually rises. The float 82, buoyed by the water, begins to float upwards. The right side of the lever 81 moves downwards, and the abutment rod 83 presses downwards accordingly. The abutment rod 83 presses down on the second valve plug 87, transmitting force to the first valve plug 85 through the connecting rod 86, causing it to overcome friction or water pressure and disengage from the abutment block 88, thus opening the passage of the connecting pipe 84. Wastewater then flows from the main tank 1 into the auxiliary tank 2 through the connecting pipe 84, safely diverting excess wastewater to the auxiliary tank 2 and preventing overflow from the main tank 1.

[0039] The above embodiment discloses a corrosion-resistant environmentally friendly wastewater recycling tank, wherein industrial wastewater containing solid impurities and harmful gases is poured in from the top inlet pipe 52. The wastewater first passes through the filter basket 54, where solid particles are intercepted. The preliminarily purified liquid flows into the main tank 1. The harmful gases emitted when the wastewater enters the main tank 1 are actively drawn in by the top gas collection component 6 through the vent pipe. The gas undergoes three stages of purification within the gas collection box 61: activated carbon (to adsorb organic matter), quicklime (to neutralize acidic gases), and an acid neutralizing agent (to neutralize alkaline gases). The purified gas is discharged through the outlet valve 66. The drive motor 71 starts, rotating the stirring shaft 72 and blades to agitate the wastewater in the main tank 1, preventing suspended solids from settling. The liquid level in the main tank 1 begins to rise. When the level reaches a preset height, the float 82 rises under buoyancy, pushing the valve plug through the lever 81 to open the connecting pipe 84 between the main tank 1 and the auxiliary tank 2. Excess wastewater in the main tank 1 is automatically diverted to the auxiliary tank 2 through the connecting pipe 84, effectively preventing overflow from the main tank 1. After treatment, the outlet valve 4 at the lowest point of the inclined surface at the bottom of the main tank 1 is opened. Because the bottom is inclined, all wastewater and sediment will collect and be completely drained.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
