[0015] A method for using a chemical liquid storage, handling, loading and unloading odor isolation and purification device, comprising: S1: The cylinder starts, driving the push plate and the slide rod to retract toward the base, and the retracted slide rod drives the end of the clamp to retract synchronously; S2: The rotating shaft on the fixed frame restricts the straight-line movement of the clamping member, causing the clamping member to rotate around the rotating shaft on the fixed frame, and the clamping member starts the clamping action; S3: When the cylinder stops shrinking and encounters obvious resistance, the storage and transportation barrels of different sizes located between the two sets of clamping members are clamped by the clamping members to the front of the fixing frame; S4: The suction member and the electric telescopic rod move to the upper end of the storage and transport barrel at the front end of the fixed frame according to the contraction of the power output end of the cylinder, and the moving distance is the contraction distance of the output end of the cylinder; S5: The electric telescopic rod is started, and the power output end of the electric telescopic rod drives the pressing block to press down the storage and transportation barrel with the open end cover, so that the end cover of the storage and transportation barrel is closed again; S6: Start the suction pump synchronously, and the annular suction part will reabsorb the harmful exhaust gas leaking from the circumference of the storage and transportation barrel into the filter box; S7: The exhaust gas passes through the primary filter chamber, activated carbon filter chamber, chemical reaction chamber and high-efficiency filter chamber in the filter box in turn, and is finally purified into clean air and discharged by the suction pump.
[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the cylinder is powered on to drive the push plate and the slide bar to shrink toward the base, and the shrinking slide bar drives the end of the clamping member to shrink synchronously. Since the end of the clamping member is rotatably connected to the end of the slide bar, and the side of the clamping member is rotatably connected to the front end of the fixed frame, the fixed frame is the fixed end, and the slide bar is the movable drive end, the two groups of clamping members are rotated around the rotating shaft on the fixed frame, and the two groups of clamping members rotate in opposite directions, so that the clamping members complete the clamping action. The alternately distributed insertion teeth and insertion grooves of the clamping members can make the two groups of clamping members overlap, thereby increasing the shrinkage range of the clamping members, so that storage barrels of different sizes can be fixed by the clamping device, avoiding manual operation of the staff, saving time and effort.
[0017] 2. In the present invention, when the output end of the cylinder begins to shrink, the mobile frame located above the fixed frame moves synchronously in the moving groove toward the cylinder direction through the linkage block that follows the movement of the sliding rod and the linkage rod fixedly connected to the mobile frame when the output end of the cylinder shrinks. The more the output end of the cylinder shrinks, the smaller the storage and transportation barrel clamped by the clamping member is, and the smaller the storage and transportation barrel is, the closer it is to the fixed frame. At this time, the mounting plate fixed above the mobile frame drives the clamping block and the air suction member to synchronously approach the direction of the fixed frame, so that the air suction member and the clamping block automatically adjust their positions according to the size of the storage and transportation barrel without manual operation and adjustment. At this time, the electric telescopic rod starts to run and drives the clamping block to clamp the opened end cover to make it close again. The air suction member starts to absorb harmful exhaust gas leaked in the surrounding area through the air suction pump and the air suction hole, thereby protecting the manual operation process of the staff and improving the work safety of the staff.
[0018] 3. In the present invention, when the exhaust gas passes through the primary filter chamber in the filter box in sequence, larger particles, dust and solid particles will be initially removed by the primary fiber cotton material, so as to protect the subsequent filter layer and extend the service life of the filter system. When passing through the activated carbon filter chamber, the organic volatiles in the gas will be absorbed and filtered by the activated carbon particles filled therein. The activated carbon has strong physical adsorption and chemical adsorption capabilities and can handle odor and harmful organic gases. When passing through the chemical reaction chamber, the chemically polluted gas will be absorbed and purified by the impregnated chemical adsorbent therein. This layer decomposes and neutralizes harmful chemicals, especially acidic, alkaline or corrosive components, by chemical adsorption or reaction. When passing through the high-efficiency filter chamber, the residual fine particles, dust and aerosols are removed by the ultra-fine glass fiber filter paper filter layer to ensure that the exhaust gas meets the cleanliness standard. Finally, the exhaust gas is purified into clean air and discharged by the suction pump, which improves the purification degree of the exhaust gas, reduces the dust and odor in the storage and transportation barrel or the surrounding area, and creates a safer, cleaner and more comfortable working environment for the staff.

After the two clamping members 1001 rotate, the insertion teeth 1002 of one of the clamping members 1001 can be inserted into the insertion groove 1003 of the other clamping member 1001, and the clamping The end of the member 1001 away from the insertion tooth 1002 is rotatably connected to the end of the slide bar 8 through the rotating shaft 17. Rotation grooves 901 are provided on both sides of the fixing frame 9. The front end of the rotation groove 901 is rotatably connected to the side of the clamping member 1001 through the rotating shaft 17. The two clamping members 1001 are provided with contact plates 1004 on the opposite sides. A telescopic spring 1005 is provided between the contact plate 1004 and the clamping member 1001. The contact plate 1004 is made of soft material and is used to contact with storage and transportation barrels of different sizes. The clamping device 10 is used to clamp storage and transportation barrels of different sizes. The slide bar 8 runs through the interior of the fixing frame 9 and is rotatably connected to the clamping device 10. By energizing the cylinder 6, the push plate 7 and the slide bar 8 are driven to retract toward the base 1, and the retracted slide bar 8 drives the end of the clamping member 1001 to retract synchronously. Since the end of the clamping member 1001 is rotatably connected to the end of the slide bar 8, and the side of the clamping member 1001 is rotatably connected to the front end of the fixed frame 9, the fixed frame 9 is the fixed end, and the slide bar 8 is the movable drive end, the two groups of clamping members 1001 are rotated around the rotating shaft 17 on the fixed frame 9, and the two groups of clamping members 1001 rotate in opposite directions, so that the clamping member 1001 completes the clamping action. The alternately distributed insertion teeth 1002 and insertion grooves 1003 of the clamping member 1001 can make the two groups of clamping members 1001 overlap, thereby increasing the retraction range of the clamping member 1001, so that storage barrels of different sizes can be fixed by the clamping device 10, avoiding manual operation by the staff, saving time and effort.
[0023] The upper end of the fixed frame 9 is movably provided with a moving frame 11, and the upper end of the fixed frame 9 is provided with two symmetrical moving grooves 902, and a moving block 903 is slidably installed inside the moving groove 902, and the moving block 903 is fixedly connected to the bottom of the moving frame 11, and a mounting plate 12 is provided at the upper end of the moving frame 11, and a support plate 13 is provided on the side of the mounting plate 12 away from the filter box 2, and a linkage block 801 is fixedly installed on the two sets of slide bars 8, and a linkage rod 802 is fixedly installed on the linkage block 801, and the linkage rod 802 is fixedly connected to the bottom of the fixed frame 9, and the filter box 2 is connected to the suction through the support connecting pipe 4. The air suction member 5 for collecting waste gas is annular, and a plurality of air suction holes 16 are arranged in an array at the annular circumference of the air suction member 5. The air suction member 5 is connected to the filter box 2 through the support connecting pipe 4 through the mounting plate 12. The end of the support connecting pipe 4 connected to the air suction member 5 is a hard pipe, and the end connected to the filter box 2 is a soft pipe. When the mounting plate 12 is moved, it will not affect the connection state between the support connecting pipe 4 and the filter box 2 because it is a soft pipe. The upper end of the support plate 13 is provided with an electric telescopic rod 14, the power output end of the electric telescopic rod 14 faces the clamping device 10, and is provided with a clamping block 15; When the output end of the cylinder 6 begins to shrink, the mobile frame 11 located above the fixed frame 9 moves synchronously in the moving groove 902 toward the cylinder 6 through the linkage block 801 that follows the movement of the slide bar 8 and the linkage rod 802 that is fixedly connected to the mobile frame 11 when the output end of the cylinder 6 shrinks. The more the output end of the cylinder 6 shrinks, the smaller the storage and transportation barrel clamped by the clamping member 1001 is, and the smaller the storage and transportation barrel is closer to the fixed frame 9. At this time, the mounting plate 12 fixed above the mobile frame 11 drives the clamping block 15 and the air suction member 5 to approach the fixed frame 9 synchronously, so that the air suction member 5 and the clamping block 15 automatically adjust their positions according to the size of the storage and transportation barrel without manual operation and adjustment. At this time, the electric telescopic rod 14 starts to run and drives the clamping block 15 to clamp the opened end cover to close it again. The air suction member 5 begins to absorb harmful exhaust gas leaked in the surrounding area through the air suction pump 3 and the air suction hole 16, thereby protecting the manual operation process of the staff and improving the work safety of the staff.
[0024] One side of the filter box 2 is connected to an air suction pump 3, and the other side of the filter box 2 is provided with a supporting connecting pipe 4. The interior of the filter box 2 includes a primary filter chamber 201, an activated carbon filter chamber 202, a chemical reaction chamber 203 and a high-efficiency filter chamber 204 in sequence. The primary filter chamber 201 is used to remove larger particles, dust and solid particles. The primary filter chamber 201 is filled with primary fiber cotton material. The activated carbon filter chamber 202 is used to remove organic volatiles in the gas. The activated carbon filter chamber 202 is filled with activated carbon particles. The chemical reaction chamber 203 is used to treat chemically polluted gases and is filled with impregnated chemical adsorbents. The high-efficiency filter chamber 204 is used to remove fine particles remaining in the gas, and a filter layer made of ultrafine glass fiber filter paper is provided inside the high-efficiency filter chamber 204. The suction end of the air suction pump 3 is arranged on the side of the ultrafine glass fiber filter paper filter layer away from the chemical reaction chamber 203; When the exhaust gas passes through the primary filter chamber 201 inside the filter box 2, larger particles, dust and solid particles will be initially removed by the primary fiber cotton material to protect the subsequent filter layer and extend the service life of the filter system. When passing through the activated carbon filter chamber 202, the organic volatiles in the gas will be absorbed and filtered by the activated carbon particles filled inside it. The activated carbon has strong physical adsorption and chemical adsorption capabilities and can handle odors and harmful organic gases. When passing through the chemical reaction chamber 203, the chemically polluted gas will be absorbed and purified by the impregnated chemical adsorbent inside it. This layer decomposes and neutralizes harmful chemicals, especially acidic, alkaline or corrosive components, through chemical adsorption or reaction. When passing through the high-efficiency filter chamber 204, the residual fine particles, dust and aerosols are removed through the ultra-fine glass fiber filter paper filter layer to ensure that the exhaust gas meets the cleanliness standard. Finally, the exhaust gas is purified into clean air and discharged by the suction pump 3, which improves the purification degree of the exhaust gas, reduces the dust and odor in the storage and transportation barrel or surrounding areas, and creates a safer, cleaner and more comfortable working environment for the staff.
[0025] First, the cylinder 6 is powered on to drive the push plate 7 and the slide bar 8 to shrink toward the base 1, and the shrinking slide bar 8 drives the end of the clamping member 1001 to shrink synchronously. Since the end of the clamping member 1001 is rotatably connected to the end of the slide bar 8, and the side of the clamping member 1001 is rotatably connected to the front end of the fixed frame 9, the fixed frame 9 is the fixed end, and the slide bar 8 is the moving drive end, the two groups of clamping members 1001 rotate around the rotating shaft 17 on the fixed frame 9, and the two groups of clamping members 1001 rotate in opposite directions, so that the clamping member 1001 completes the clamping action; When the output end of the cylinder 6 begins to shrink, the mobile frame 11 located above the fixed frame 9 moves synchronously in the moving groove 902 toward the cylinder 6 through the linkage block 801 that follows the slide bar 8 and the linkage rod 802 that is fixedly connected to the mobile frame 11. When the output end of the cylinder 6 shrinks, the mobile frame 11 moves synchronously in the moving groove 902 toward the cylinder 6. The more the output end of the cylinder 6 shrinks, the smaller the storage and transportation barrel clamped by the clamping member 1001 is, and the smaller the storage and transportation barrel is closer to the fixed frame 9. At this time, the mounting plate 12 fixed above the mobile frame 11 drives the clamping block 15 and the suction member 5 to approach the fixed frame 9 synchronously. At this time, the electric telescopic rod 14 starts to run and drives the clamping block 15 to press the opened end cover to close it again. The suction member 5 starts to absorb the harmful exhaust gas leaked in the surrounding area through the suction pump 3 and the suction hole 16, and the exhaust gas is adsorbed into the filter box 2; When the exhaust gas passes through the primary filter chamber 201 in the filter box 2 in sequence, larger particles, dust and solid particles will be initially removed by the primary fiber cotton material to protect the subsequent filter layer and extend the service life of the filter system. When passing through the activated carbon filter chamber 202, the organic volatiles in the gas will be absorbed and filtered by the activated carbon particles filled inside. The activated carbon has strong physical adsorption and chemical adsorption capabilities and can handle odors and harmful organic gases. When passing through the chemical reaction chamber 203, the chemically polluted gas will be absorbed and purified by the impregnated chemical adsorbent inside. This layer decomposes and neutralizes harmful chemicals, especially acidic, alkaline or corrosive components, through chemical adsorption or reaction. When passing through the high-efficiency filter chamber 204, the residual fine particles, dust and aerosols are removed through the ultra-fine glass fiber filter paper filter layer to ensure that the exhaust gas meets the cleanliness standard. Finally, the exhaust gas is purified into clean air and discharged by the suction pump 3.
