Description

Technical Field

[0001] The utility model belongs to the technical field of volatile organic compounds, and particularly relates to a leaching and extraction device for volatile organic compounds in solid waste. Background Technique

[0002] In environmental detection, it is necessary to detect various wastewaters, waste gases and solid wastes. Some solid wastes contain volatile organic compounds, so corresponding leaching and extraction devices are needed.

[0003] After retrieval, the patent with the publication number CN215026159U discloses a leaching and extraction device for volatile organic compounds in solid waste, including a leaching device cavity. Inside the leaching device cavity, a gas cavity, a piston, a solid waste sample storage device and a filter membrane support sieve are arranged in sequence from bottom to top. This device solves the problems of sealing, leaching and preservation in the leaching process of volatile organic compounds (VOCs) in solid waste. However, it has the following deficiencies in use:

[0004] 1. When the above device is in use, the leaching agent is directly injected into the receiving bottle by an airtight needle. As the leaching agent increases, the pressure in the receiving bottle will increase, making it difficult to inject, and the receiving capacity of the leaching agent is limited.

[0005] Therefore, we propose a leaching and extraction device for volatile organic compounds in solid waste. Content of the Utility Model

[0006] The purpose of the utility model is to solve the problem that when the existing device is in use, the leaching agent is directly injected into the receiving bottle by an airtight needle. As the leaching agent increases, the pressure in the receiving bottle will increase, making it difficult to inject, and the receiving capacity of the leaching agent is limited. A leaching and extraction device for volatile organic compounds in solid waste is proposed.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A leaching and extraction device for volatile organic compounds in solid waste, comprising:

[0009] A device main body, one side of the device main body is fixedly provided with a mounting frame, and a connecting pipe is fixedly penetrated through the surface of the mounting frame. The connecting pipe is communicated with the device main body;

[0010] A receiving bottle, the receiving bottle is arranged on one side of the mounting frame. The top end of the receiving bottle is threadedly connected with a bottle cap. A rubber plug and a fixed pipe are fixedly penetrated through the surface of the bottle cap. A sealing block is slidably connected to the inner wall of the fixed pipe. A spring is fixedly arranged between the sealing block and the fixed pipe. A plurality of air holes are opened on the outer wall of the sealing block. A first sealing ring is fixedly arranged on the inner wall of the fixed pipe. The sealing block abuts against the first sealing ring;

[0014] In a possible design, the limiting mechanism includes a lifting plate. The lifting plate is arranged on one side of the mounting rack, and the receiving bottle is arranged on the lifting plate. Through grooves are respectively formed in the outer walls on both sides of the lifting plate, and two limiting rods are slidably connected between the through grooves. Two fixing blocks are fixedly arranged on the outer wall of one side of the lifting plate, and a bidirectional lead screw is rotatably penetrated between the fixing blocks. The bidirectional lead screw respectively threadedly penetrates through the two limiting rods.

[0015] In a possible design, the lifting mechanism includes an electric push rod and two lifting grooves. The electric push rod is fixedly arranged on one side of the mounting rack, and the lifting grooves are respectively formed in the outer wall of one side of the mounting rack. A connecting plate is slidably connected between the lifting grooves. One end of the connecting plate passes through the lifting groove and is fixed to the lifting plate, and the output shaft of the electric push rod is fixed to the connecting plate.

[0016] In a possible design, the conveying mechanism includes a water pump. The water pump is fixedly arranged on the surface of the equipment main body. The water inlet end of the water pump is fixedly communicated with a liquid inlet pipe, and the other end of the liquid inlet pipe passes through the surface of the equipment main body and extends to the inside of the equipment main body.

[0018] In a possible design, the surface of the fixed pipe is provided with an annular inclined surface.

[0019] In this application, during use, rotate the bidirectional lead screw to drive the limiting rods to move until the distance between the limiting rods is appropriate. Then place the receiving bottle between the limiting rods. Then start the electric push rod to drive the connecting plate and the lifting plate to move, thereby driving the receiving bottle to rise, so that the airtight needle pierces into the rubber stopper. At the same time, the connecting pipe enters the fixed pipe to push the sealing block to move downward, so that the sealing block disengages from the first sealing ring, allowing air flow to pass through the ventilation holes to balance the pressure inside the receiving bottle. Then open the control valve, and then start the water pump to pump the leaching agent into the receiving bottle.
