Description

Technical Field

[0002] A filter holder is a container for placing filter membranes before, during and after sampling. Its main function is to fix the filter membranes.

[0003] In the prior art, in order to facilitate the storage of filter membrane clips and determine the order of filter membrane clips, the filter membrane clips are stacked in sequence in the filter membrane barrel. The filter membrane clips in the filter membrane barrel are in a stacked form and are coaxially confined in the filter membrane barrel. When the filter membrane clips in the filter membrane barrel are to be taken out, the upper cover of the filter membrane barrel needs to be opened, and then the filter membrane clips therein are taken out from the mouth of the upper cover of the filter membrane barrel in sequence. This operation is very troublesome. It is inconvenient to manually remove the filter membrane clips inside the filter membrane barrel, and it is even more inconvenient to remove the filter membrane clips at the bottom of the filter membrane barrel. If the filter membrane barrel is directly tilted and the filter membrane clips are poured out from the mouth above the filter membrane barrel, this method will cause the filter membrane clip to vibrate. The vibration of the filter membrane clip will cause the filter membrane adsorbed with particulate matter in the filter membrane clip to vibrate, which may affect the state of particulate matter on the filter membrane in the filter membrane clip and affect the subsequent observation or weighing operation of the filter membrane.

It is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the protection scope of the present invention.

[0025] Embodiment 1:

[0026] In the prior art, it is not easy to take out the filter membrane clip from the filter membrane barrel. In order to facilitate the removal of the filter membrane clip from the filter membrane barrel, the filter membrane clip storage tube provided in Embodiment 1 of the present invention is convenient for taking out the filter membrane clip. Figures 1 to 4As shown, it includes a storage tube body 1 for storing stacked filter membrane clips; a cylindrical cavity 11 is arranged in the storage tube body 1; the axis of the cylindrical cavity 11 extends in the vertical direction; a filter membrane clip inlet 12 and a filter membrane clip outlet 13 are respectively arranged on the upper and lower bottom surfaces of the cylindrical cavity of the storage tube body 1; the filter membrane clip entering the cylindrical cavity 11 from the filter membrane clip inlet 12 can flow out from the filter membrane clip outlet 13; a blocking component 2 that can block the filter membrane clip outlet 13 is arranged at the filter membrane clip outlet 13; the blocking component 2 can switch between a blocking state and a non-blocking state; in the blocking state, the blocking component 2 blocks the filter membrane clip outlet 13, and the filter membrane clip in the cylindrical cavity 11 cannot flow out from the filter membrane clip outlet 13; in the non-blocking state, the blocking component 2 does not block the filter membrane clip outlet 13, and the filter membrane clip in the cylindrical cavity 11 can flow out from the filter membrane clip outlet 13.

[0027] When the filter membrane clamp storage tube provided by the utility model embodiment 1 is used, the filter membrane clamps are stacked and placed in the cylindrical cavity 11 of the storage tube body 1, and the cylindrical cavity 11 can limit the filter membrane clamps in the cylindrical cavity 11 to be coaxial; the first filter membrane clamp entering the storage tube body 1 enters the cylindrical cavity 11 from the filter membrane clamp entrance 12, and is blocked by the blocking component 2 in the blocking state and cannot flow out of the cylindrical cavity 11 from the filter membrane clamp outflow outlet 13, and the subsequent filter membrane clamps are blocked by the previous filter membrane clamp entering the storage tube body 1 in turn, thereby completing the stacking of the filter membrane clamps in the storage tube body 1; when the filter membrane clamp in the storage tube body 1 needs to be taken out, the state of the blocking component 2 is changed to make the blocking component 2 in the non-blocking state, so that the filter membrane clamp can flow out from the filter membrane clamp outflow outlet 13. Compared with the prior art that requires tipping to take out the filter membrane clamp, in this embodiment, the filter membrane clamp in the storage tube body 1 can be taken out by placing the storage tube body 1 on the desktop and making the blocking component in the non-blocking state. The filter membrane clip flows out from the filter membrane clip outflow port 13 at the bottom of the storage tube body 1. This not only simplifies the process of taking out the filter membrane clip (no need to pick out the filter membrane clip by hand, and no need to dump it), but also reduces the shaking of the filter membrane clip during the removal process (the filter membrane clip taken out in this embodiment is always the filter membrane clip directly blocked by the blocking component 2, because after taking out a filter membrane clip, the remaining filter membrane clips will move downward by a distance of the thickness of the filter membrane clip due to gravity, so each time the filter membrane clip is taken out, it is close to the filter membrane clip outflow port 13; while in the prior art The filter membrane clamp removal method, when implemented with the device of this embodiment, needs to tip over the storage cylinder body 2 and remove the filter membrane clamp from the filter membrane clamp entrance port 12. However, since the distances from different filter membrane clamps to the filter membrane clamp entrance port 12 are inconsistent, after the filter membrane clamp close to the filter membrane clamp entrance port 12 is taken out, the remaining filter membrane clamps will produce more displacement when being taken out. During the displacement process, the filter membrane clamp may collide with the side wall of the filter membrane barrel, thereby causing vibration of the filter membrane in the filter membrane clamp, affecting the distribution of particulate matter on the filter membrane, and affecting subsequent detection work.

[0028] The filter membrane clip storage cylinder for easy removal of the filter membrane clip provided in Example 1 of the utility model solves the problem of difficulty in taking out the filter membrane clips stacked and stored in the filter membrane barrel in the prior art, and can facilitate the taking out of the filter membrane clips.

[0029] In order to limit the taking out of one filter membrane clamp at a time, in the present embodiment, a base 3 is further included; the storage tube body 1 is detachably fixed on the base 3; a receiving groove 31 for receiving the filter membrane clamp is provided on the base 3; the filter membrane clamp flow outlet 13 is arranged opposite to the receiving groove 21; when the storage tube body 1 is fixed on the base 3, the filter membrane clamp flow outlet 13 is flush with the plane where the opening of the receiving groove 31 is located; the depth of the receiving groove 31 is equal to the thickness of a piece of filter membrane clamp. The base 3 is provided with a receiving groove 21 which can just accommodate a filter membrane clamp. This can simplify the operation of vertically moving the storage tube body 1 up to a certain height to take out a filter membrane clamp. When the storage tube body 1 is set on the base 3, the blocking component is in an unblocking state, and a filter membrane clamp will flow out of the storage tube body 1 at the filter membrane clamp outflow outlet 13 into the receiving groove 31. At this time, although the blocking component is still in an unblocking state, the remaining filter membrane clamps in the storage tube body 1 will not fall out of the cylindrical cavity 11 due to the support of the filter membrane clamp in the receiving groove 21. At this time, the blocking component is in a blocking state. Except for the filter membrane clamp that is already in the receiving groove 31, the remaining filter membrane clamps will be blocked in the cylindrical cavity 11. When the storage tube body 1 is removed from the base 3, there will be a filter membrane clamp in the receiving groove 31 of the base 3.

[0030] To facilitate the control of the switching state of the blocking component 2, in the present embodiment, the blocking component 2 includes a plurality of spring pieces 21; the spring piece 21 can be rotatably fixed at the membrane clamp flow outlet 13; the spring piece 21 includes a natural state and a compressed state; in the natural state, one end of the spring piece 21 can block part of the membrane clamp flow outlet 13; in the compressed state, the spring piece 21 does not block the membrane clamp flow outlet 13; the spring piece 21 is in a natural state under normal conditions; a plurality of tightening blocks 32 corresponding in number and position to the spring piece 21 are provided on the base 3; after the storage tube body 1 is fixed on the base 3, the tightening block 32 can tighten the spring piece 21, so that the spring piece 21 is transformed from the natural state to the compressed state. The blocking component 2 does not necessarily need to completely block the membrane clamp flow outlet 13. The spring sheet 21 blocks part of the membrane clamp flow outlet 13, thereby limiting the flow of the membrane clamp from the cylindrical cavity with the same diameter as the membrane clamp. The structure for controlling the state change of the spring sheet 21 is arranged on the base 3. On the one hand, this facilitates the state switching of the blocking component 2. On the other hand, it can prevent the situation where multiple membrane clamps fall off at one time due to accidental switching of the state of the blocking component 2. When the storage tube body 1 is separated from the base 3, the tightening block 32 on the base will no longer tighten the spring sheet 21, and the spring sheet 21 will immediately change to a natural state, thereby instantly blocking the membrane clamp flow outlet 13, thereby avoiding the need for the staff to take out multiple membrane clamps at one time because they forget to change the state of the blocking component.

[0031] In order to specifically realize that the state of the spring piece 21 is changed by the tightening block 32, and the function of blocking and not blocking the filter membrane clamp flow outlet 13 is realized, in the present embodiment, the blocking assembly 2 also includes a mounting frame 22; the mounting frame 22 is fixed on the storage tube body 1; the spring piece 21 includes a rotating block 211 and a spring 212; the rotating block 211 can be rotatably fixed on the mounting frame 22; one end of the spring 212 is fixed on the mounting frame 22, and the other end of the spring 212 is tightened on the rotating block 211; when the storage tube body 1 is fixed on the base 3, the tightening block 32 can tighten the rotating block 211 to rotate relative to the mounting frame 22, and the rotating block 211 is tightened to the compressed state of the spring piece 21; when the storage tube body 1 is separated from the base 3, the spring 212 can tighten the rotating block 211 to rotate relative to the mounting frame 22, and the rotating block 211 is tightened to the natural state of the spring piece 21. The rotating block 211 can be rotatably fixed on the mounting frame 22. In the natural state of the spring piece 21, the rotating block 211 is tightened by the spring 212, so that the rotating block 211 can block the filter clamp flow outlet 13. When the storage cylinder body 1 is fixed on the base 3, the tightening block 32 will contact the rotating block 211 to make the rotating block 211 rotate relative to the mounting frame 22. The rotating block 211 rotates to not block the filter clamp flow outlet 13, and the spring 212 is compressed at the same time; when the storage cylinder body 1 is removed from the base 3, the spring 212 will re-tighten the rotating block 211 due to its own elasticity until the rotating block 211 blocks the filter clamp flow outlet 13.

[0032] In order to facilitate the tightening block 32 on the base 3 to be just tightened to the rotating block 211, in this embodiment, a plurality of positioning holes 14 are opened at the bottom of the storage tube body 1; a plurality of positioning pins 33 are provided on the base 3; the positioning pins 33 match the positioning holes 14 in size; when the storage tube body 1 is fixed on the base 3, the positions of the positioning holes 14 and the positioning pins 33 correspond respectively. The connection method of the positioning pins 33 and the positioning holes 14 belongs to the prior art and will not be described in detail here. The plurality of positioning pins 33 and the plurality of positioning holes 14 define the connection angle between the storage tube body 1 and the base 3, so as to facilitate the alignment of the tightening block 32 on the base 3 with the rotating block 211 on the storage tube body 1.

[0033] As a preferred solution, in this embodiment, the storage tube body 1 is provided with a plurality of magnets 15 at the contact surface with the base 3; the base 3 can be adsorbed by the magnets 15. The adsorption of the magnets at the bottom of the storage tube body 1 and the base 3 ensures that the base 3 and the storage tube body 1 are in close contact, which is conducive to the tightening operation of the tightening block 32 on the base 3 on the rotating block 211.
