Description

Technical Field

[0001] This utility model relates to the field of diluent technology, and in particular to a gas diluent. Background Technology

[0002] A gas diluter is a precision laboratory tool used to adjust the concentration of gas mixtures to meet specific analytical requirements. It achieves precise dilution by controlling the gas flow rate. In environmental monitoring, it is used for the detection of air pollutants, diluting high-concentration samples to the instrument's measurable range, avoiding instrument overload and extending equipment life. In industrial processes, it ensures safe production and reduces the risk of explosion. In chemical experiments and reagent development, it provides reliable data support. This device is easy to operate, reliable, and highly efficient in improving detection accuracy and reducing errors. It assists in air quality assessment and process optimization, making it an indispensable assistant in modern scientific and technological practice.

[0003] A search revealed Chinese Patent Publication No. CN218774614U, which discloses a standard gas gradient diluter, including a connector, a one-way valve, and a syringe. The connector has an octagonal column structure with an internal eight-way tube. Eight insertion rods are located on each side of the connector's side surface. A connecting block is located at the end of the one-way valve away from the connector. The syringe is inserted into the inner wall of the connecting block. A piston plate is slidably connected to the inner wall of the syringe. An injection push rod for pushing the piston plate is located on the outer wall of one side of the piston plate. An injection port is fixedly connected to the outer wall of one side of the syringe, located on the inner wall of the connecting block. A stabilizing mechanism is located at the end of the syringe near the connecting block to maintain syringe stability. This utility model, through the stabilizing mechanism, prevents the syringe from shifting under stress, thus avoiding gaps between the syringe and the connecting block, allowing external air to enter the connector and cause contamination.

[0044] Specifically, the bottom of the outer wall of the adjusting block 701 is fixedly connected to the top of the outer wall of the pulley 6. The inner wall of the adjusting block 701 is connected to the lead screw 704 by threads. The top of the outer wall of the lead screw 704 is connected to the motor 706.

[0045] Reference Figure 1 , Figure 2 and Figure 3 A pneumatic solenoid valve 10 is fixedly connected to the top of the outer wall of the partition 3. A second air pipe 9 is connected to the outer wall of the pneumatic solenoid valve 10. A pressure accumulator box 12 is connected to the bottom of the outer wall of the pneumatic solenoid valve 10. A diversion pipe 11 is connected to the bottom of the outer wall of the pressure accumulator box 12. Compressed air enters the pressure accumulator box 12 through the pneumatic solenoid valve 10. The pressure accumulator box 12 stores pressure. When needed, it is released through the diversion pipe 11 and flows into each filter box 401 to achieve the effect of backflushing and cleaning.

[0046] Specifically, a pneumatic solenoid valve 10 is fixedly connected to the top of the outer wall of the partition 3. The outer wall of the solenoid valve is connected to the second air pipe 9, and the bottom is connected to the accumulator box 12. The bottom of the outer wall of the accumulator box 12 is connected to the diversion pipe 11. Compressed air is introduced into the accumulator box 12 through the pneumatic solenoid valve 10. The accumulator box 12 is used to store the pressure of the compressed air. When cleaning is required, the accumulator box 12 releases the stored pressure, and the pressure flows into each filter box 401 through the diversion pipe 11 to achieve backflushing cleaning to remove blockages and maintain filtration efficiency.

[0047] Working principle: First, after the mixed gas enters the system, it flows through the two-stage filtration structure of the filter box 401, which includes two purification stages: a coarse filter element 4042 and a fine filter element 4043. The coarse filter element 4042 is responsible for intercepting larger particles in the gas to complete the initial filtration, while the fine filter element 4043 continues to filter smaller particles in the gas to ensure the filtration effect. When the filter element becomes clogged, the air compressor 801 is started. The air compressor 801 draws in external air, and the compressed air is delivered to the pneumatic solenoid valve 10 through the second air pipe 9. The pneumatic solenoid valve 10 guides the compressed gas into the pressure accumulator box 12 for temporary storage. When cleaning is required, the compressed gas stored in the pressure accumulator box 12 is diverted through the diverter pipe 11 and flows back into the filter chamber 402 of each filter box 401 to complete the reverse flushing of the clogged filter element, thereby realizing the filtration function and self-cleaning mechanism of the system.

[0048] Furthermore, the sliding column 702 and the spring 703 work together in the adjusting mechanism 7 to provide buffering and support, effectively improving the stability and durability of the mechanism. The inner wall of the spring 703 is directly and fixedly connected to the outer wall of the sliding column 702 to form a firm bond. When the top motor 706 starts, it drives the lead screw 704 to rotate. The rotation of the lead screw 704 is connected to the adjusting block 701 through threaded coupling. The adjusting block 701 achieves vertical displacement upward or downward under the drive of the threaded structure. This automatic mechanism can accurately adjust the height of the pulley 6 without any human intervention to meet diverse work requirements, significantly enhancing the adaptability and reliability of the equipment.
