Description

Technical Field

[0034] Example:

[0035] like Figure 1-3 As shown, the utility model provides an anti-dumping suction filtration purification device, comprising:

[0036] A workbench 1, a suction pipeline 2, a suction filter support 3 and a suction filter bottle 4, wherein the suction filter support 3 is arranged on the workbench 1, the suction filter bottle 4 is arranged on the bottom plate of the suction filter support 3, at least two suction filter bottles 4 are simultaneously connected to the suction pipeline 2 through a connecting pipe 6, the suction pipeline 2 is connected to an air pump, a funnel 5 is inserted on the suction filter bottle 4, and a filter paper is arranged in the funnel 5;

[0037] Two suction filtration bottle mounting grooves 7 are arranged on the bottom plate of the suction filtration bracket 3 , and two clamping pieces 8 are symmetrically connected to the side walls of the suction filtration bottle mounting grooves 7 , and the clamping pieces 8 clamp the outer wall of the suction filtration bottle 4 .

[0038] The suction filtration bottle 4 is conical in shape, and a sealing plug 9 is connected to the bottle mouth, and the funnel 5 is inserted into the sealing plug 9 .

[0039] An upper branch pipe 41 and a lower branch pipe 42 are connected to both sides of the suction bottle 4, respectively. The end of the upper branch pipe 41 is tilted upward, a valve is provided on the lower branch pipe 42, and a notch for accommodating the lower branch pipe 42 is provided on the side of the suction bottle installation groove 7.

[0040] A plurality of suction branch pipes 10 are arranged on the suction pipeline 2 . The plurality of suction branch pipes 10 are connected to the suction filter bottle 4 through the connecting pipes 6 , respectively. The suction branch pipes 10 are provided with valves.

[0042] The working principle and beneficial effects of the above technical solution are:

[0043] A dump-proof suction filtration purification device is disclosed. A suction filtration bottle 4 is arranged as a structure similar to a conical bottle, an upper branch pipe 41 and a lower branch pipe 42 are arranged on the side of the bottle body, the upper branch pipe 41 is connected to a suction branch pipe 10 through a connecting pipe 6, and a plurality of suction filtration bottles 4 are arranged at the same time, which are respectively connected to the plurality of suction branch pipes 10; a sealing plug 9 is installed at the bottle mouth of the suction filtration bottle 4, a funnel 5 is inserted into the sealing plug 9, and filter paper is laid in the funnel 5; the suction filtration bottle 4 is installed in a suction filtration bottle installation groove 7 and clamped by a clamp 8; a cross bar 32 on a suction filtration bracket 3 is adjusted to a suitable position, and a dropper is fixed by a dropper clamp 33, and the dropper is located directly above the suction filtration bottle 4. When the device is in use, the solution in the dropper flows into the funnel 5, and the vacuum pump is started to suck out the air in the suction pipeline 2, thereby reducing the internal air pressure and forming a negative pressure in the suction bottle 4. Due to the effects of atmospheric pressure and gravity, the solution in the filter paper of the funnel 5 will flow through the filter paper into the suction bottle 4 below to achieve filtration.

[0044] The beneficial effects of the above technical solution are:

[0045] The present application provides an anti-dumping suction filtration purification device, in which multiple groups of suction bottles 4 are connected to a suction pump at the same time, and the air pressure in the suction bottle 4 is reduced by the suction of the suction pump. Due to the effects of atmospheric pressure and gravity, the solution in the filter paper flows into the suction bottle 4 below through the filter paper, and the residual solid remains on the filter paper, thereby achieving the purpose of filtering multiple groups of suction bottles at the same time. The suction bottle 4 is installed in the suction bottle installation groove 7 and fixed by a clip 8, which can prevent the suction bottle 4 from tipping over due to sudden changes in air pressure or unstable air pressure during the suction process, thereby improving the stability of the suction bottle 4 and avoiding tipping over caused by accidental human contact during operation.

[0046] In one embodiment, Figure 4-6 As shown, the clip 8 is arranged in an arc shape, and the top end of the clip 8 is hinged to the side wall of the filter bottle installation groove 7, and a clip spring 11 is connected between the bottom end of the clip 8 and the side wall of the filter bottle installation groove 7.

[0047] A sliding frame assembly is provided at the bottom of the filter bottle installation groove 7, and the sliding frame assembly includes an upper sliding frame 12 and a lower sliding frame 13. The lower sliding frame 13 is connected to the bottom of the filter bottle installation groove 7, and the upper sliding frame 12 is sleeved on the lower sliding frame 13 and slides relatively therewith.

[0048] The top end of the lower sliding frame 13 and the bottom end of the upper sliding frame 12 are connected with flanges 14 that are engaged with each other.

[0049] A linkage component is arranged in the space formed by the upper sliding frame 12 and the lower sliding frame 13, and the linkage component includes:

[0050] A ratchet 15, the ratchet 15 is rotatably connected to the inner wall of the suction bottle mounting groove 7 through a rotating shaft 16, and a first coil spring is provided at the connection between the rotating shaft 16 and the suction bottle mounting groove 7;

[0051] The rotating arm 17 is V-shaped, the center of the rotating arm 17 is hinged to the bottom of the suction filter bottle installation groove 7 and a second coil spring is arranged at the hinge. One end of the rotating arm 17 close to the ratchet 15 is connected with a ratchet 18, and the ratchet 18 is engaged with the ratchet 15. The top surface of the other end of the rotating arm 17 is arranged to be a plane.

[0052] The linkage push rod 19 is connected to the bottom surface of the upper sliding frame 12 and corresponds to the end plane of the rotating arm 17.

[0053] A wire wheel 20 is connected to the rotating shaft 16 , a connecting wire 21 is wound around the wire wheel 20 , and the other end of the connecting wire 21 is simultaneously connected to one side of the two clips 8 away from the side wall of the suction bottle installation groove 7 .

[0054] The working principle and beneficial effects of the above technical solution are:

[0055] When the suction bottle 4 is installed in the suction bottle mounting groove 7, the suction bottle 4 is put in from the top of the suction bottle mounting groove 7, and the two clamping pieces 8 are in a state of being separated from each other; when the suction bottle 4 contacts the upper sliding frame 12 at the bottom of the suction bottle mounting groove 7, the upper sliding frame 12 is pressed downward, and the linkage push rod 19 at the bottom of the upper sliding frame 12 moves downward accordingly, squeezing the end of the rotating arm 17 away from the ratchet 15 to rotate downward, and the second coil spring is stored in energy when the rotating arm 17 rotates; the other end of the rotating arm 17 rotates upward, so that the ratchet 18 on the rotating arm 17 is separated from the ratchet 15. After the ratchet 15 loses its constraint, it rotates forward rapidly under the action of the first coil spring, driving the wire wheel 20 to rotate synchronously, and the connecting line 21 is tightened and wound around the wire wheel 20. The connecting line 21 pulls the two clamping pieces 8 to rotate upward and approach each other, and the clamping piece 8 is clamped on the suction bottle 4, so that the suction bottle 4 is clamped and fixed.

[0056] When the suction bottle 4 needs to be taken out, the suction bottle 4 is lifted up, and the rotating arm 17 is quickly reset under the action of the second coil spring, pushing the linked push rod 19 and the upper sliding frame 12 to reset upward, and the ratchet 18 is re-engaged with the ratchet 15; when the suction bottle 4 moves upward, as the diameter of the contact position gradually increases, the suction bottle 4 squeezes the clip 8 to rotate downward and move away from each other, and the clip 8 pulls the connecting line 21 to drive the wire wheel 20 to rotate in the opposite direction, and drives the ratchet 15 to rotate in the opposite direction through the rotating shaft 16, and stores energy for the first coil spring during rotation; when the ratchet 15 rotates in the opposite direction, it is limited by the ratchet 18 so that the ratchet 15 can rotate to the preset position and lock, so that the clip 8 returns to the initial state of being far away from each other again, and a sufficient spacing is reserved to facilitate the insertion of the suction bottle 4.

[0057] Through the above-mentioned structural design, the relative position of the clamping piece 8 can be adjusted according to the insertion state of the suction bottle 4; when the suction bottle 4 is not inserted, the clamping piece 8 is in a state of being far away from each other, and a sufficient distance is reserved to reduce the resistance encountered when the suction bottle 4 is inserted; after the suction bottle 4 is inserted, the clamping piece 8 is automatically switched to a state of being close to each other, so as to clamp and fix the suction bottle 4 and improve the stability of the suction bottle 4.
