Technical Field

[0001] The utility model relates to a liquid hazardous waste storage and transportation box used for temporarily storing and transporting hazardous waste liquids. Background Art

[0002] In the daily production and testing process, a large amount of liquid hazardous waste will be generated and needs to be temporarily stored and transported. According to relevant national regulations, such substances cannot be discharged at will and need to be stored in designated areas. Considering the danger of the waste liquid itself, the storage container needs to have good performance.

[0003] At present, it is common to use anti-corrosion barrels. However, due to the cylindrical structure of the barrel, it is inconvenient to stack. Generally, additional auxiliary parts are needed to help stack, such as adding steel frames. In addition, the barrel filled with waste liquid is very heavy, and it is extremely inconvenient to transport and dump it. The pressure of the gas in the barrel cannot be controlled, which poses a safety hazard. Utility Model Content

[0004] The present application proposes a liquid hazardous waste storage and transportation box, which aims to solve the inconvenience of stacking and transportation, and solve the problem that the gas pressure in the barrel cannot be controlled.

[0005] In order to achieve the above technical objectives, this application adopts the following technical solutions:

[0007] Preferably, a liquid level observation chamber is provided on the side of the box body.

[0008] Preferably, the box cover is composed of a metal cover body and a sealing ring made of PTFE material.

[0009] Preferably, a lock body is provided on the box cover.

[0010] Preferably, a liquid discharge valve is provided at the liquid discharge port.

[0011] Preferably, the inlet filter screen includes an annular fixing ring and a fire-retardant microporous filter screen connected to the bottom of the annular fixing ring.

[0012] Due to the adoption of the above-mentioned technical solution, the present application solves the problem of box space stacking by setting the ground feet and the top slots, and solves the problem of box transportation by setting the forklift slots on the box; at the same time, by setting the exhaust device, it can achieve filtering and balancing the internal and external pressure differences.

[0018] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0019] See also Figure 1 and Figure 2 As shown, the liquid hazardous waste storage and transportation box of this embodiment includes: a square box body 1, a filtering system, an exhaust system, etc.

[0020] Combination Figure 1 and Figure 2As shown, a square box 1 is welded with stainless steel metal plates, a liquid injection port 2 is opened on the top of the box 1, and slots 3 are set at the four corners of the top plate, and pads 4 are attached to the slots 3. Four feet 5 are provided at the bottom of the box 1, and each foot is provided with an inclination matching the slots. When different boxes are stacked, the inclination of the feet is inserted into the slots 3, and the box 1 is raised as a whole by the pads 4 to avoid interference with the rollers 6 at the bottom of the box 1. Two forklift slots 7 are provided at the corresponding two sides of the bottom of the box 1, so that the box can be raised by forklift for easy transportation. A bottom plate 8 with an inclination of 7° is provided at the bottom of the box 1, and a liquid storage space is provided between the bottom plate 8 and the top plate. The side plate of the box 1 is provided with a drain port at the lowest point of the bottom plate 8, and a drain valve 9 is installed to control it.

[0021] The liquid injection port 2 is fixedly connected with a box cover 10 by a locking screw 101. The box cover 10 is composed of a metal cover body and a sealing ring made of PTFE material, which can ensure that it will not be corroded by acid and alkali substances that may exist in the waste liquid, so that the sealing performance of the box cover 10 is extremely high. A lock body is provided on the box cover, which can increase the safety of storage and avoid problems caused by misoperation.

[0022] The utility model is provided with two filtrations, namely an inlet filter screen 11 and an outlet filter screen 12. The inlet filter screen 11 is removably arranged in the liquid injection port 2. Figure 3 As shown, the inlet filter screen 12 includes an annular fixing ring 121 and a fire-retardant microporous filter 122 connected to the bottom of the annular fixing ring. The annular fixing ring 121 is provided with a disassembly waist hole 1211, and the fixing is completed by disassembling the waist hole 1211 and cooperating with the bayonet on the side of the injection port 2. The inlet filter screen 11 can achieve preliminary filtration, and preliminarily filter the solid waste that may exist in the waste liquid and the fixed sediment that may be produced, to ensure that the hazardous waste in the box is liquid. The filtering structure is a stainless steel fire-retardant mesh structure, which can effectively prevent flames from entering the interior of the box while meeting the filtering requirements, and prevent the occurrence of accidental fires. The secondary filtration of the discharge port can ensure that the treated waste liquid and the solid waste generated during the storage process are filtered for the second time, and no more solid precipitate waste will be transferred and processed separately. The two filtering devices can be disassembled for cleaning and reinstalled.

[0023] Exhaust device 13 such as Figure 4As shown, it is arranged on the top plate. The exhaust device 13 includes: a filter housing 131, a pressure rod 132, a filter element 133 and a spring 134. The filter housing 131 is penetrated on the top plate, and the side of the filter housing 131 is provided with an air outlet 1311, the lower end is provided with an air inlet 1312, and the side is provided with a sealing groove 1313. The pressure rod 132 is penetrated on the top of the filter housing 131. The filter element 133 is fixed in the filter housing 131, and is located below the pressure rod 132. The spring 134 is fixed between the filter element 133 and the air inlet 1312. When the air pressure in the box body 1 is higher than that outside, the gas in the box body 1 will push the spring, the filter element and the pressure rod upward to open the air outlet 1311. When the internal and external air pressures are balanced, the pressure rod will push the spring to restore the state of closing the air inlet 1312. When hazardous waste is stored in the box for a long time, it will volatilize, or chemical reactions will generate gases, or during the injection and drainage process, the pressure changes in the box will cause the workpiece to not move smoothly. The top exhaust device can work in time to adjust the pressure in the box to a normal state without affecting storage and use. The top exhaust device is also equipped with a filter to filter the exhaust gas and adsorb harmful substances to ensure the safety of the exhaust gas.

[0024] In addition, a waste liquid observation chamber 14 is provided on the side wall of the box body 1, and a liquid level height indicator 15 is provided in the box so that the fullness of the waste liquid in the box can be visually observed.

[0025] A caster assembly 16 is provided at the bottom of the box 1, so that the box can be moved a short distance or its posture can be adjusted without a forklift; the casters can be locked for fixed use.

[0026] The above-described embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. Equivalent changes and modifications made to the present invention by those skilled in the art should all fall within the scope of the claims attached to the present invention.
