Description

Technical Field

[0001] The utility model relates to the field of laboratory waste liquid treatment, in particular to a laboratory waste liquid collecting device. Background Art

[0002] In all kinds of chemical laboratories, such as inorganic, analytical, organic, and scientific research laboratories, there is the problem of collecting and treating chemical waste liquids. The waste liquids used in these experiments have diverse components and high content of harmful substances. They cannot be discharged directly and need to be collected and transported to the corresponding treatment centers for unified treatment.

[0003] At present, most of the waste liquid is collected by waste liquid barrels, waste liquid tanks, waste liquid tanks and other equipment. There are some problems in the use of these equipment. On the one hand, when pouring waste liquid into the collection device, the collection device has a small caliber, which is easy to pour outside the collection device, or splash everywhere and fall on the body of the experimenter, posing a potential risk of injury. On the other hand, when pouring, the lid needs to be opened, and some volatile components inside are easy to spread to the laboratory, causing certain impacts on the environment and the experimenter. In addition, according to the requirements for waste liquid transportation, the waste liquid barrel cannot be filled, and a certain space must be reserved for the volatilization of solvents and other liquids. However, in laboratories with a large number of people, this point is often ignored, and the waste liquid barrel is often filled. When sorting out the waste liquid at the end, the excess waste liquid needs to be put into another barrel, which is time-consuming and laborious, and prone to danger. At the same time, some existing devices also have defects such as inconvenient transportation, lack of waste liquid monitoring system, poor intelligence and automation, and low integration. Utility Model Content

[0004] The purpose of the utility model is to solve the following problems existing in the prior art: the existing waste liquid collection device is prone to dumping and splashing when collecting waste liquid, and has defects such as inconvenient transportation, lack of waste liquid monitoring system, poor intelligence and automation, and low integration.

[0005] In order to solve the problems existing in the prior art, the utility model provides a laboratory waste liquid collection device, including a collector, a collection box and a barrel body, wherein the top of the collection box is provided with a collector, and the collector includes a cover, a drainage rod, a magnetic gravity control valve, a pump pre-valve, a drainage pump, a connecting pipe and a barrel body, a liquid level meter is provided at one end of the collection box, and a lower base is provided at the bottom of the collection box.

[0006] Furthermore, an upper cover is provided on the top of the collector, and handles are provided on both sides of the upper cover, so that the staff can conveniently lift the upper cover by holding the handles to open the collector.

[0007] Furthermore, the lower base includes a pump rear valve, a bottom plate and a fixer, and the fixer is connected with bolts. The staff pushes the device to the waste liquid treatment center, opens the pump front valve and the pump rear valve, and starts the drainage pump to perform drainage work.

[0008] Furthermore, the lid is in a conical structure and is threadedly connected to the magnetic gravity control valve. The magnetic gravity control valve can prevent the volatile components inside from overflowing when no liquid is poured out, and play a sealing role. When pouring waste liquid, the seal is opened according to the amount of waste liquid flowing in; on the other hand, if there is too much waste liquid inside, it can also prevent the waste liquid from being overfilled, flowing back, and overflowing.

[0009] Furthermore, the drainage rod is in the shape of an L-shaped hexagonal prism, and the drainage rod is inserted into the pipe wall of the collector inlet, and the drainage rod is higher than the collector inlet. The drainage rod allows the waste liquid to flow down along the drainage rod, preventing the liquid from flowing to the outer wall of the pouring vessel when pouring the waste liquid, preventing the liquid from directly contacting the hand, and also preventing the liquid from splashing, overflowing, and flowing to the outer wall of the collector.

[0010] Furthermore, a push rod is provided on the other side of the collection box, and a roller is provided at the bottom of the collection box. The staff can drive the equipment to move by pushing the roller to roll through the push rod, which is convenient for the staff to transport the waste liquid.

[0011] Furthermore, a control console is provided on one side of the collection box, and the control console includes control buttons and a display screen. Through the monitoring and control of the control console, the pH, temperature, pressure, COD, liquid level and other indicators of the waste liquid can be understood, which can prevent some accidents from happening on the one hand, and provide reference data for subsequent waste liquid treatment on the other hand.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. A drainage rod is set at the mouth of the collector, and the waste liquid flows down along the drainage rod to prevent the liquid from flowing to the outer wall of the pouring vessel when pouring the waste liquid, prevent the liquid from directly contacting the hands, and also prevent the liquid from splashing, overflowing, and flowing to the outer wall of the collector;

[0014] 2. A magnetic gravity control valve is set at a certain height (usually 10 cm) from the collector mouth. On the one hand, it prevents the volatile components inside from overflowing when there is no liquid being dumped, and plays a sealing role. When dumping waste liquid, the seal is opened according to the amount of waste liquid flowing in; on the other hand, if there is too much waste liquid inside, it can also prevent the waste liquid from being overfilled, backflowing, and overflowing;

[0015] 3. Through monitoring and control, we can understand the pH, temperature, pressure, COD, liquid level and other indicators of the waste liquid, which can prevent some accidents from happening on the one hand, and provide reference data for subsequent waste liquid treatment on the other hand;

[0016] 4. The collector is equipped with wheels and can be moved freely without effort, which is convenient for the transportation of waste liquid. The liquid flows into the waste liquid treatment center through the drainage pump, without manual dumping, which saves effort. In addition, the liquid pipeline is placed under the barrel, which is also convenient for the waste liquid to be discharged in time;

[0017] 5. The device is automated, highly integrated, occupies a small area, and is convenient and practical. BRIEF DESCRIPTION OF THE DRAWINGS
