Description

Technical Field

[0001] This utility model relates to the field of chemical experimental technology, specifically to a multifunctional chemical experimental filtration device. Background Technology

[0002] Filtration is a common processing method in chemical experiments. Its core is to remove insoluble solid impurities from liquids through filtration, thereby obtaining a purer liquid. This technology has wide applications in many fields such as chemical synthesis, analysis and testing, and substance separation.

[0003] In existing manual filtration devices, operators need to hold a guide rod to guide the solution during use. However, the guide rod is prone to shaking when held, which may cause liquid to splash into the external environment. To address this problem, a multifunctional chemical experimental filtration device is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is as follows: the guide rod is prone to shaking when held, which may cause liquid to splash into the external environment.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-5 As shown, a multifunctional chemical experimental filtration device includes an adjustment mechanism 1, with a filtration mechanism 2 disposed on one side of the adjustment mechanism 1. The adjustment mechanism 1 includes a base 101, with a vertical rod 102 fixedly installed at one end of the top surface of the base 101. A lifting sleeve 103 is slidably sleeved on the upper end of the outer wall of the vertical rod 102. An extension rod 107 is fixedly connected to the middle of one side of the lifting sleeve 103, and a support ring 108 is fixedly installed at the other end of the extension rod 107. A clamping plate 109 is fixedly installed on one side of the top of the lifting sleeve 103. A rotating cylinder 110 is disposed on the inner side of the clamping plate 109. A rotating shaft 115 is fixedly connected to the middle of the side of the rotating cylinder 110. The rotating shaft 115 is rotatably connected to the inner wall of the clamping plate 109, and the end of the rotating shaft 115 extends to the outer wall of the clamping plate 109. A nut 116 is threadedly connected to the end of the rotating shaft 115, and the surface of the nut 116 abuts against the clamping plate 109. Figure 1As shown, loosen nut 116 to separate it from clamp 109, so that rotating shaft 115 can drive rotating cylinder 110 and the inner side of clamp 109 to rotate;

[0029] Among them, a guide rod 117 is connected through the inner wall of the rotating cylinder 110;

[0030] A collection container 118 is placed in the center of the top surface of the base 101.

[0031] A rotating component 111 is threadedly connected to the upper end of the inner wall of the rotating cylinder 110. The top of the rotating component 111 is located above the rotating cylinder 110. A fixing ring 112 is fixedly installed on the lower end of the inner wall of the rotating cylinder 110. Extrusion plates 113 are fixedly connected to both sides of the top of the fixing ring 112. Abutments 114 are fixedly connected to the top of each of the two extrusion plates 113. The inner sides of the extrusion plates 113 and the abutments 114 are abutted by uniformly spaced guide rods 117. The two abutments 114 are symmetrically arranged on both sides of the fixing ring 112, and the outer edges of the abutments 114 are beveled, extending outwards from top to bottom. The inner wall of the rotating component 111 is hollowed out in the middle, and the inner diameter of the hollowed-out lower end of the rotating component 111 gradually increases from top to bottom. The lower end of the inner wall of the rotating component 111 is movably connected to both abutments 114. Figures 3-4 As shown, when the rotating part 111 descends, the top of the abutment 114 retracts inward;

[0032] The lower end of the lifting sleeve 103, located on the side away from the clamping plate 109, is fixedly connected to a connecting frame 104. A threaded rod 105 is threadedly connected to the inner wall of the connecting frame 104. One end of the threaded rod 105 abuts against the outer wall of the upright 102, and the other end of the threaded rod 105 is fixedly connected to a knob 106. Figure 2 As shown, the threaded rod 105 abuts against the side of the upright 102, thereby fixing the lifting sleeve 103 to the outside of the upright 102. Anti-slip pads are installed on the side of the upright 102 to increase friction with the threaded rod 105.

[0033] The filtration mechanism 2 includes a funnel 201, which abuts against the inner side of the support ring 108. The lower end of the funnel 201 extends into the collection container 118, and filter paper 202 is movably sleeved on the upper inner wall of the funnel 201. The upper inner wall of the funnel 201 is symmetrically provided with mounting grooves 203. Clamping rods 204 are movably installed inside the two mounting grooves 203, and the surfaces of the two mounting grooves 203 are in contact with the filter paper 202.

[0034] The working principle of this utility model:

[0035] When the device is in use, the rotating component 111 is rotated. Under the compression of the thread, the rotating component 111 moves up and down along the inner wall of the rotating cylinder 110. When the rotating component 111 rises, the inner wall of the rotating component 111 gradually separates from the abutment 114, so that neither the abutment 114 nor the extrusion plate 113 extrudes the inner guide rod 117. At this time, the guide rod 117 can be adjusted up and down along the inner wall of the rotating cylinder 110. Conversely, when the rotating component 111 falls, the abutment 114 is pushed to move inward, and then the abutment 114 and the extrusion plate 113 together clamp the side of the guide rod.

[0036] Next, loosen the nut 116 so that the rotating cylinder 110 rotates on the inner wall of the clamping plate 109. Then, insert the guide rod 117 into the funnel 201 according to the above steps, and the bottom end of the guide rod abuts against the inner side of the filter paper 202.

[0037] After filtration is complete, push the clamping rods 204 into the funnel 201 so that the two clamping rods 204 clamp the outer wall of the filter paper 202. Lifting the clamping rods upward will separate the filter paper 202 from the inner wall of the funnel 201.

[0038] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
