Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and more specifically, to a laboratory waste gas treatment device. Background Technology

[0002] Laboratory exhaust gases include common pollutants such as acid mist, formaldehyde, benzene compounds, and various organic solvents, as well as less common pollutants such as mercury vapor and phosgene. Specific exhaust gases are generated during chemical experiments in the laboratory. These gases need to be purified before being released to prevent environmental pollution.

[0003] Existing laboratory exhaust gas treatment devices generally remove harmful substances by spraying a purification liquid to make it react chemically with the exhaust gas. However, in actual operation, the exhaust gas enters the treatment device through pipes for treatment, making it difficult to control the amount of exhaust gas entering. When the amount of exhaust gas entering at one moment is large, it is difficult to make sufficient contact with the purification liquid, resulting in poor purification effect.

[0004] In view of this, we propose a laboratory exhaust gas treatment device. Utility Model Content

[0026] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Please see Figure 1-5 This utility model provides a technical solution:

[0029] A laboratory waste gas treatment device includes a treatment box 1, a purification box 2 disposed inside the treatment box 1, a filter box 3 disposed on the upper side of the purification box 2, an inlet pipe 4 penetrating through the inner side of the purification box 2, an exhaust pipe 5 fixedly disposed inside the purification box 2, the other end of the exhaust pipe 5 penetrating through the filter box 3 and extending to the inner side, a first sealing block 6 movably disposed on the outer side of the inlet pipe 4 located on the inner side of the purification box 2, a connecting plate 7 fixedly disposed on the outer side of the first sealing block 6, a second sealing block 8 connected to the exhaust pipe 5 fixedly disposed on the outer side of the connecting plate 7, and two sets of fixed cylinders 9 fixedly disposed on the outer side of the inlet pipe 4, each set of fixed cylinders 9 having a connecting rod 10 movably inserted into its inner side, the connecting rod 10 movably penetrating through the fixed cylinder 9 and extending to the outer side. The outer end of the connecting rod 10 is fixedly connected to the first sealing block 6 on the outer side of the fixed cylinder 9. A first spring 11 is provided inside the fixed cylinder 9, with one end connected to the fixed cylinder 9 and the other end connected to the connecting rod 10. A rotating rod 12 is rotatably provided inside the purification box 2, and a protrusion 13 for docking the connecting plate 7 is fixedly sleeved on the outer side of the rotating rod 12. A motor 14 is fixedly provided on the outer side of the treatment box 1, with the power end of the motor 14 moving through the treatment box 1 and fixedly connected to the rotating rod 12. The first spring 11 does not deform in its initial state. When the protrusion 13 presses against the connecting plate 7, the first sealing block 6 moves, causing the connecting rod 10 to move. The movement of the connecting rod 10 stretches the first spring 11, causing it to deform. Subsequently, through the release of the elastic potential energy of the first spring 11, the connecting rod 10 and the first sealing block 6 can be moved and reset, thereby blocking the air inlet pipe 4, facilitating intermittent air intake, and improving the treatment effect of waste gas.

[0030] Specifically, a fan 15 is installed on the inner side of the exhaust pipe 5, which is located on the outer side of the treatment box 1. When the fan 15 is turned on by an external power source, the purified exhaust gas can be drawn into the filter box 3, thereby further improving the treatment efficiency of the exhaust gas and improving the convenience of exhaust.

[0031] Furthermore, a spray purification mechanism 16 is provided inside the purification box 2. The spray purification mechanism 16 mainly consists of a water tank outside the treatment box 1 and an atomizing nozzle inside the purification box 2. A water pump is installed inside the water tank, and a water pipe is installed outside the water pump. The water pipe is connected to the atomizing nozzle. When the water pump is turned on, the purification liquid in the water tank can be drawn out and sprayed out through the atomizing nozzle, thereby purifying the exhaust gas.

[0032] It is worth noting that an installation plate 17 is provided on the outside of the treatment box 1, and multiple sets of filter plates 18 are provided on the inside of the installation plate 17. The multiple sets of filter plates 18 are movable through the filter box 3 and extend to the inside. Multiple sets of mounting grooves for docking the filter plates 18 are opened through the outside of the filter box 3. The multiple sets of filter plates 18 can perform multi-layer filtration of exhaust gas, and can further filter harmful substances and purified liquid in exhaust gas, thereby improving the treatment effect of exhaust gas.

[0033] It is worth noting that a fixed frame 19 is fixedly installed on the outside of the treatment box 1, and a movable block 20 is movably installed on the inside of the fixed frame 19. Connecting blocks 21 are rotatably installed on both sides of the movable block 20. Limiting blocks 22 are rotatably installed on the outside of both sets of connecting blocks 21. The limiting blocks 22 movably pass through the fixed frame 19 and extend to the outside. A locking block is fixedly installed on the part of the limiting block 22 located on the outside of the fixed frame 19. The mounting plate 17 has slots for docking locking blocks on both sides. The two sets of limiting blocks 22 can limit the mounting plate 17, thereby facilitating the quick installation and fixing of the mounting plate 17 and the filter plate 18 and improving the ease of installation.

[0034] In addition, a movable rod 23 is fixedly installed on the outside of the movable block 20. The movable rod 23 moves through the fixed frame 19 and extends to the outside. A handle 24 is fixedly installed on the outer end of the movable rod 23 located on the outside of the fixed frame 19. A second spring 25 is sleeved on the outside of the movable rod 23. One end of the second spring 25 is connected to the fixed frame 19, and the other end of the second spring 25 is connected to the movable block 20. The second spring 25 does not deform in its initial state. When the mounting plate 17 is disassembled, the movable rod 23 and the movable block 20 are moved by pushing the handle 24 upward. When the movable block 20 moves, it drives the connecting block 21 and the limiting block 22 to move, thereby causing the limiting block 22 to move and separate from the mounting plate 17, making it easier to disassemble the mounting plate 17. When the movable block 20 moves, it stretches the second spring 25, causing the second spring 25 to deform. Subsequently, through the release of the elastic potential energy of the second spring 25, it can drive the movable rod 23 and the movable block 20 to move and reset, thereby facilitating the limiting block 22 to limit and fix the mounting plate 17, further improving the ease of loading and unloading the mounting plate 17.

[0035] It must be said that a sliding rod 26 is fixedly installed on the inner side of the fixed frame 19. The sliding rod 26 moves through the limiting block 22. The sliding rod 26 can limit the limiting block 22, so that the limiting block 22 can move parallel to the sliding rod 26, thereby making it easier to limit and fix the mounting plate 17.

[0036] Working principle: First, the air inlet pipe 4 is connected to the external exhaust gas pipe. By turning on the spray purification mechanism 16, the water pump can draw out the purification liquid in the water tank and spray it out through the atomizing nozzle. The motor 14, turned on by the external power supply, can drive the rotating rod 12 and the protrusion 13 to rotate. When the protrusion 13 rotates, it squeezes the connecting plate 7. The connection plate 7 is squeezed, which drives the first sealing block 6 and the second sealing block 8 to move. When the first sealing block 6 moves, it drives the connecting rod 10 to move and stretches the first spring 11, causing the first spring 11 to deform. Subsequently, the rebound force of the first spring 11 can drive the connecting rod 10 and the first sealing block 6 to move and reset. With the continuous squeezing of the connecting plate 7 by the protrusion 13, the first sealing block 6 and the second sealing block 8 open intermittently, so that the exhaust gas can fully contact the purification liquid. At the same time, the purified exhaust gas enters the filter box 3 through the exhaust pipe 5. The multiple filter plates 18 in the filter box 3 can filter the exhaust gas and improve the treatment effect of the exhaust gas.
