Description

Technical Field

[0001] The invention relates to the field of experimental tables, in particular to a comprehensive experimental table for laboratories. Background Art

[0002] The laboratory bench is one of the most important equipment in the laboratory. It is a table used for experimental testing and storage of instruments. Experimenters conduct various experimental tests on the laboratory bench, during which they will use corresponding materials to complete the experimental tests. Waste liquid is often generated during the experimental test. The waste liquid comes from the washing of the instruments and experimental tests. Since the laboratory bench is equipped with filters, storage barrels, etc., the waste liquid is first temporarily placed in the waste liquid bottle. Then, at the end of the experimental test, the waste liquid in the waste liquid bottle is poured out and filtered through the filter and then stored in the storage barrel.

[0003] In the process of transferring waste liquid on the existing laboratory bench, the experimenter needs to pour out the waste liquid in the waste liquid bottle by hand. In order to prevent the waste liquid from splashing, the experimenter needs to move slowly and keep steady when pouring the waste liquid, which increases the labor intensity of the experimenter. If the waste liquid has irritating, volatile and other properties, the experimenter also needs to wear goggles, etc.; for waste liquid containing impurities, it is necessary to pour out part of the waste liquid periodically when pouring out the waste liquid - waiting for the waste liquid to be filtered by the filter. In this process, the waste liquid is easy to accumulate on the filter in large quantities, and the filter has a slow filtering speed for the waste liquid; the waste liquid in the waste liquid bottle cannot be poured out periodically when it is poured out, and the gravitational potential energy of the waste liquid cannot be gradually increased during the pouring, and it is impossible to prevent the filter residue after the last waste liquid is filtered by the filter from hindering the waste liquid from being filtered by the filter this time, and it is impossible to ensure that the waste liquid poured out each time is completely filtered by the filter.

[0049] The supporting replacement drive component includes a first connecting seat 34, which is arranged in the processing box 11 and is located directly below the supporting replacement seat 19. A second telescopic motor 35 is arranged between the first connecting seat 34 and the supporting replacement seat 19.

[0051] The splash-proof ring plate 14 is an ultra-high molecular weight polyethylene plate, which can move up and down more smoothly in the liquid inlet 12, reduce the friction with the treatment box 11, and reduce the splashing waste liquid remaining on its inner wall; the liquid collecting guide ring plate 17 is an ultra-high molecular weight polyethylene plate, which can reduce the waste liquid filtered by the filter 15 remaining on its inner wall. The ultra-high molecular weight polyethylene plate has corrosion resistance and self-lubricating properties.

[0052] Working principle:

[0053] The main body 10 of the experimental table is used by experimenters to conduct experimental tests and store instruments. The processing box 11 is used to carry components and has a predetermined storage space. The liquid inlet 12 facilitates the waste liquid in the waste liquid bottle 13 to be poured into the processing box 11 after the experimenter finishes the experimental test. The filter 15 filters the waste liquid when the waste liquid in the waste liquid bottle 13 is poured into the processing box 11.

[0054] The supporting plate 22, the suction cup (not shown), the elastic clip 23, and the first compression spring 24 are arranged in cooperation to support the body of the waste liquid bottle 13, to adsorb and fix the bottom of the waste liquid bottle 13, and to limit and fix the bottleneck of the waste liquid bottle 13 when the experiment test is completed and the experimenter is operating it, so as to support and fix the waste liquid bottle 13, thereby preventing the waste liquid bottle 13 from shaking during the period when the waste liquid in the waste liquid bottle 13 is poured into the processing box 11 through the liquid inlet 12, and improving the stability of the waste liquid when it is poured into the processing box 11, thereby preventing the waste liquid bottle 13 from detaching and falling during the period when the waste liquid in the waste liquid bottle 13 is poured into the processing box 11 through the liquid inlet 12, and preventing the waste liquid bottle 13 from breaking on the processing box 11 or the laboratory table main body 10.

[0055] The matching arrangement of the connecting seat 27, the rotating shaft 28, the rotating motor 29, and the extending seat 30 is used to drive the rotating frame between the supporting bodies to rotate. The matching arrangement of the connecting ring seat 31, the extending groove 32, and the second compression spring 33 allows the splash-proof ring plate 14 to move up and down with the filter screen 15 in the liquid inlet 12 during the period when the waste liquid is periodically poured into the processing box 11 through the liquid inlet 12 and the waste liquid contacts the filter screen 15. The splash-proof ring plate 14 prevents the waste liquid from splashing onto the outer surface of the processing box 11 or the laboratory table body 10 during the period when the waste liquid is periodically poured into the processing box 11 through the liquid inlet 12 and the waste liquid is filtered by the filter screen 15.

[0056] After the waste liquid bottle 13 is supported and fixed, the rotating frame in the supporting room is driven to rotate toward the liquid inlet 12 at a predetermined speed for a first predetermined time, and then stop rotating for a second predetermined time, and repeat this process several times, so that the waste liquid in the waste liquid bottle 13 is periodically poured into the treatment box 11 through the liquid inlet 12; during the waste liquid transfer process, the experimenter does not need to pour out the waste liquid in the waste liquid bottle 13 by hand, and when pouring the waste liquid, the experimenter does not need to move slowly and keep stable to prevent the waste liquid from splashing, thereby relieving the labor intensity of the experimenter, and if the waste liquid has irritating, volatile and other properties, the experimenter does not need to wear goggles, etc.; For waste liquid containing impurities, it is necessary to periodically pour out part of the waste liquid when pouring out the waste liquid - waiting for the waste liquid to be filtered by the filter 15. During this process, the waste liquid is not easy to accumulate on the filter 15 in large quantities. The waste liquid periodically poured into the treatment box 11 can be fully filtered by the filter 15 before the next rotation of the support room rotary rack toward the liquid inlet 12, and the filtering speed of the filter 15 for the waste liquid is greatly improved; the waste liquid in the waste liquid bottle 13 of the support room rotary rack is all poured into the treatment box 11 through the liquid inlet 12, and then driven to rotate to the initial position. After the support room rotary rack rotates to the initial position, it is operated by the experimenter to remove the waste liquid bottle 13.

[0057] The cooperation of the first telescopic motor 25 and the connecting plate 26 is arranged to drive the driving member of the intermediate rotating frame to rise a predetermined vertical distance each time the rotating frame of the supporting room stops rotating. When the waste liquid in the waste liquid bottle 13 is poured out, the gravitational potential energy of the waste liquid can be gradually increased, thereby increasing the degree of up and down movement of the splash-proof ring plate 14 and the filter screen 15 in the liquid inlet 12, so that the waste liquid is spread on the filter screen 15 before the rotating frame of the supporting room periodically rotates toward the liquid inlet 12 next time, thereby preventing the filter residue after the waste liquid was filtered by the filter screen 15 last time from interfering with the filtration of the waste liquid by the filter screen 15 this time, and ensuring that the waste liquid poured out each time is completely filtered by the filter screen 15.

[0058] The storage barrel 16 is used to store the waste liquid filtered by the filter screen 15 , and the liquid collecting guide ring plate 17 is used to move with the splash-proof ring plate 14 and collect and guide the waste liquid filtered by the filter screen 15 into the inlet pipe of the storage barrel 16 when the waste liquid is filtered by the filter screen 15 .

[0059] The first connecting seat 34, the second telescopic motor 35, the second connecting seat 36, and the third telescopic motor 37 are arranged in coordination to drive the supporting replacement seat 19 to move. The supporting replacement seat 19 is driven to support and fix the storage barrel 16 during the period when the storage barrel 16 does not store a predetermined range of waste liquid filtered by the filter 15, so that the bottom end of the liquid collecting guide ring plate 17 is located in the inlet pipe of the storage barrel 16; when the storage barrel 16 stores a predetermined range of waste liquid filtered by the filter 15 and the supporting room rotating frame does not support and fix the waste liquid bottle 13, the supporting replacement seat 19 is driven to first descend a predetermined vertical distance, so that the storage barrel 16 is separated from the bottom end of the liquid collecting guide ring plate 17 by its own gravity, thereby eliminating the need for the experimenter to manually operate The storage barrel 16 is separated from the bottom end of the liquid collecting guide ring plate 17 to reduce the labor intensity of the experimenters, and then moved toward the opening 18 of the processing box 11 until it is moved to the outside of the processing box 11, so that the storage barrel 16 can be removed and the new storage barrel 16 can be supported and fixed; the supporting replacement seat 19 is driven to reset to the initial position after the new storage barrel 16 is supported and fixed, so that the bottom end of the liquid collecting guide ring plate 17 enters the inlet pipe of the new storage barrel 16, thereby eliminating the need for the experimenters to manually operate the bottom end of the liquid collecting guide ring plate 17 to enter the inlet pipe of the new storage barrel 16, thereby reducing the labor intensity of the experimenters; there is no need for the experimenters to manually operate the separation or installation of the storage barrel 16 from the laboratory table throughout the whole process, and the labor intensity is low.

[0060] The connecting frame 38 and the fourth telescopic motor 39 are arranged in coordination to drive the two stabilizing and fixing plates 20 to move. The two stabilizing and fixing plates 20 are driven to fit the anti-splashing ring plate 14 during the period when the bottom end of the liquid collecting guide ring plate 17 is located in the inlet pipe of the storage barrel 16, so as to increase the stability of the up and down movement of the anti-splashing ring plate 14 during the period when the anti-splashing ring plate 14 and the filter screen 15 move up and down in the liquid inlet 12, thereby preventing the bottom end of the liquid collecting guide ring plate 17 from interfering with the inlet pipe of the storage barrel 16 when the liquid collecting guide ring plate 17 follows the anti-splashing ring plate 14 to prevent the bottom end of the liquid collecting guide ring plate 17 from being deformed and / or damaged, and preventing the liquid collecting guide ring plate 17 from being deformed and / or damaged. The bottom end of the plate 17 is not slidably connected with the inlet pipe of the storage barrel 16, so as to prevent the bottom end of the liquid collecting guide ring plate 17 from being unable to enter the inlet pipe of the new storage barrel 16; the two stabilizing and fixing plates 20 are driven to press against the anti-splashing ring plate 14 before the bottom end of the liquid collecting guide ring plate 17 enters the inlet pipe of the new storage barrel 16, so as to fix the anti-splashing ring plate 14 and the liquid collecting guide ring plate 17 at the same time, so as to prevent the bottom end of the liquid collecting guide ring plate 17 from deflecting before entering the inlet pipe of the new storage barrel 16 and make the bottom end of the liquid collecting guide ring plate 17 accurately located in the inlet pipe of the new storage barrel 16; the storage barrel 16 is not easy to deflect when installed on the laboratory bench and can be accurately installed.

[0061] The solenoid valve 21 is closed when the rotating frame in the supporting room is not supporting and fixing the waste liquid bottle 13 to seal the storage barrel 16, thereby preventing the odor in the storage barrel 16 from escaping to the periphery of the laboratory table body 10. The solenoid valve 21 is opened when the rotating frame in the supporting room is supporting and fixing the waste liquid bottle 13.
