Abstract
Description
Technical Field
[0001] This utility model belongs to the field of waste recycling, and in particular relates to a waste liquid collection tank that can be operated in a closed manner with full-process visualization. Background Technology
[0002] Waste liquid collection tanks are widely used in chemical industry laboratories and production workshops during shutdown maintenance. Before a chemical plant shutdown for maintenance, it is necessary to wash, replace, and recycle materials in the system, and to confirm the drainage of the system's low-point drains. Traditional drainage tanks consist only of a tank body, lid, and handle, and are mostly made of opaque materials. During drainage, transfer, and pouring, it is difficult to collect the volatilized waste liquid and any entrained toxic gases, easily causing alarms for excessive toxic gases, seriously affecting personnel health and safety. To solve this problem, in practice, plastic sheeting is often used to protect the waste liquid tank and the work area, and negative pressure suction is used. However, the protective process requires significant manpower and resources, often slowing down the maintenance progress. Furthermore, because the waste liquid tank is not sealed, toxic gases inside can still volatilize during the transfer and pouring of the waste liquid, posing a risk of poisoning to personnel.
[0003] Meanwhile, when confirming whether the system has finished draining, in order to more accurately determine whether the drain has been completely drained, the traditional confirmation method requires using objects such as paper towels or plastic films to sense that there is gas flowing at the drain outlet after no more liquid continues to flow out of the drain. Therefore, it is inevitable that toxic gas will escape into the environment.
[0004] Therefore, it is necessary to provide a new type of waste liquid collection tank that allows for visualization and closed-loop operation to solve the above problems. Utility Model Content
[0005] In order to solve the above technical problems, the purpose of this utility model is to provide a new type of waste liquid collection tank with full-process visualization and closed operation in the confirmation stage, the discharge stage, the waste liquid tank transfer stage and the waste liquid recycling stage.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A waste liquid collection tank with full-process visualization and airtight operation, the waste liquid collection tank includes: a handle (1), a lid assembly (2) and a tank body (3) which are fully adapted together, and three sets of clamping buckles (9) on the top of the tank body (3).
[0008] The barrel (3) is a hollow structure, and a drain valve (4) is installed at the bottom. The drain valve (4) is connected to a quick male connector or a quick female connector by a thread.
[0009] A liquid receiving pipe (5) and an exhaust pipe (7) are installed on the top of the lid assembly (2). A downward one-way magnetic anti-backflow mechanism (6) is installed inside the liquid receiving pipe (5); an upward one-way magnetic anti-backflow mechanism (8) is installed inside the exhaust pipe (7); and a matching drain pipe (10) is installed.
[0010] In this invention, the waste liquid collection tank utilizes a novel transparent material, at least in the lid and receiving pipe, providing visibility while maintaining resistance to acid and alkali corrosion and chemical solvents. Furthermore, a magnetic suction mechanism is integrated into the receiving and venting pipes. During drainage and waste liquid recovery, the magnetic suction mechanism achieves basic self-sealing characteristics; its operation determines whether the drain has been completely drained; and a drain valve and components at the bottom of the tank ensure a sealed operation during waste liquid recovery, thus achieving full visibility and self-sealing. This invention is compact, portable, visually appealing, and highly airtight, making it particularly suitable for confirming the complete discharge of toxic and hazardous liquids in chemical plants and for waste liquid collection in laboratories.
[0011] In one embodiment of this utility model, the bucket lid assembly (2) consists of a bucket lid ring, a silicone sealing ring, and a transparent cover plate.
[0012] In one embodiment of this utility model, the barrel lid ring is made of one or more of 304 stainless steel, HDPE, and PP.
[0013] In one embodiment of this utility model, the inner diameter of the bucket lid ring is 200mm-500mm, and the outer diameter is 250mm-600mm.
[0014] In this invention, the transparent cover is made of one or more of the following materials: PP, PVC, PET, PMMA, PC, and glass.
[0015] In this invention, the barrel body (3) is made of one or more of the following materials: 304 stainless steel, HDPE, and PP.
[0016] In one embodiment of this utility model, the volume of the barrel (3) is 10-100L.
[0017] In one embodiment of this utility model, the diameter of the liquid receiving tube (5) is 32-50mm.
[0018] In this invention, the receiving tube (5) is one or more of the following materials: PP, PVC, PET, PMMA, PC, and glass.
[0019] In one embodiment of this utility model, a hollow sealing plug made of soft silicone is installed at the opening of the liquid receiving tube (5).
[0020] In one embodiment of this utility model, the exhaust pipe (7) has a diameter of 50-75mm.
[0021] In one embodiment of this utility model, a drain pipe (10) is matched with a receiving pipe (5). The drain pipe has an outer diameter of 20mm-40mm and can be inserted into a silicone sealing plug inside the receiving pipe to form a seal with the elastic silicone sealing port.
[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0023] By observing the different actions of the transparent receiving tube and the built-in magnetic attraction mechanism under different working conditions, it can be determined whether the material in the system has been completely discharged; the overall sealing design achieves full-process sealing of the discharge confirmation process, transfer process, and recovery process; thus achieving no contact with highly toxic materials throughout the entire working process.

Detailed Implementation
[0025] The present invention will be further described below through specific embodiments. The embodiments described herein are merely illustrative and do not limit the scope of the present invention.
[0026] Example 1
[0027] A novel waste liquid collection tank with fully visualized and closed-loop operation is shown in the structural diagram below. Figure 1 As shown, it includes a handle (1), a lid assembly (2), a bucket body (3), a drain valve (4), a receiving pipe (5), a downward-facing one-way magnetic anti-backflow mechanism (6), an exhaust pipe (7), an upward-facing one-way magnetic anti-backflow mechanism (8), three sets of clamping latches (9), and a matching drain pipe (10). Its specific structure is as follows:
[0028] The barrel (3) is made of 304 stainless steel and has a volume of 12L. A drain valve (4) is installed at the bottom. A quick connector is installed on the drain valve to connect the hose for draining.
[0029] The bucket lid assembly (2) consists of a bucket lid ring, a silicone sealing ring, and a transparent cover plate; the bucket lid ring is made of 304 stainless steel with an inner diameter of 240mm and an outer diameter of 300mm; the transparent cover plate is made of PC material for easy observation of the internal liquid.
[0030] The lid assembly (2) is fully compatible with the body (3). In addition to the sealing ring on the inside of the lid, there are three sets of clamping buckles on the top of the body to fix the lid.
[0031] A liquid receiving pipe (5) and an exhaust pipe (7) are installed above the lid. The liquid receiving pipe (5) is made of transparent PP material with a diameter of 32mm and has a downward one-way magnetic anti-backflow mechanism (6) installed inside. The exhaust pipe (7) is made of transparent PP material with a diameter of 50mm and has an upward one-way magnetic anti-backflow mechanism (8) installed inside. The magnetic mechanism in the liquid receiving pipe is normally closed, allowing the medium to flow in one direction to prevent gas from escaping from the barrel. The magnetic mechanism in the exhaust pipe is also normally closed, allowing the medium to flow out one direction to prevent pressure buildup inside the barrel. It also prevents internal gas from escaping when the pressure inside the barrel is low.
[0032] The working process of the waste liquid collection tank in this embodiment is as follows:
[0033] During the confirmation operation of draining a system containing toxic and hazardous media, the matching drain pipe (10) (outer diameter 20mm) connected to the system is inserted into the silicone sealing plug of the receiving pipe for draining. The drain pipe and the elastic silicone receiving pipe opening can be sealed. Under the action of liquid gravity, the magnetic suction mechanism opens, the liquid flows into the tank, the pressure inside the tank increases, the magnetic suction mechanism located in the exhaust pipe opens, and the gas phase is discharged through the exhaust pipe. The exhaust pipe opening is connected to a negative pressure suction device to suck up the waste gas inside the tank.
[0034] When confirming the drainage operation of a system containing toxic and harmful media, connect a negative pressure suction device to the exhaust pipe to suction the waste gas in the tank. Regardless of whether the system is under normal or positive pressure, observe whether liquid is continuously flowing out of the receiving pipe. If the system drainage system is unobstructed, it indicates that there is still a lot of liquid in the system that has not been completely drained. If a small amount of liquid flows out and the magnetic suction mechanism in the receiving pipe remains open, it can be determined that the system drainage system is unobstructed and that the liquid material in the system has been completely drained. If no liquid flows out or a small amount of liquid flows out and the magnetic suction mechanism in the receiving pipe does not activate, it indicates that the system drainage system is blocked and needs to be cleared.

Figure 1 As shown, it includes a handle (1), a lid assembly (2), a bucket body (3), a drain valve (4), a receiving pipe (5), a downward-facing one-way magnetic anti-backflow mechanism (6), an exhaust pipe (7), an upward-facing one-way magnetic anti-backflow mechanism (8), three sets of clamping latches (9), and a matching drain pipe (10). Its specific structure is as follows:
[0037] The barrel (3) is made of HDPE and has a volume of 100L. A drain valve (4) is installed at the bottom. A quick connector is installed on the drain valve to connect the hose for draining.
[0038] The bucket lid assembly (2) consists of a bucket lid ring, a silicone sealing ring, and a transparent cover plate; the bucket lid ring is made of HDPE material with an inner diameter of 500mm and an outer diameter of 600mm; the transparent cover plate is made of PC material to facilitate observation of the internal liquid;
[0039] The lid assembly (2) is fully compatible with the body (3). In addition to the sealing ring on the inside of the lid, the body and lid are connected by threads. There are also three sets of clamping buckles on the top of the body to fix the lid.
[0040] A liquid receiving pipe (5) and an exhaust pipe (7) are installed above the lid. The liquid receiving pipe (5) is made of transparent PP material with a diameter of 50mm and has a downward one-way magnetic anti-backflow mechanism (6) installed inside. The exhaust pipe (7) is made of transparent PP material with a diameter of 78mm and has an upward one-way magnetic anti-backflow mechanism (8) installed inside. The magnetic mechanism in the liquid receiving pipe is normally closed, allowing the medium to flow inward in one direction to prevent gas from escaping from the barrel. The magnetic mechanism in the exhaust pipe is also normally closed, allowing the medium to flow outward in one direction to prevent pressure buildup inside the barrel. It also prevents internal gas from escaping when the pressure inside the barrel is low.
[0041] The working process of the waste liquid collection tank in this embodiment is the same as in Embodiment 1.
