Detailed Description

The drawings are for illustrative purposes only and are not to be construed as limiting the patent; for the purpose of better illustrating the embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, so to speak, as communicating between the two elements. The specific meaning of the above terms in the present invention can be understood in specific cases for those skilled in the art. The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.

As shown in fig. 1, the present embodiment discloses an anti-clogging solvent receiving tank liquid level meter mounting structure, which includes a solvent receiving tank 1, an outwardly protruding mounting seat 2 is mounted at a non-axial center position of the bottom of the solvent receiving tank 1, a convex diaphragm type liquid level meter 3 is fixedly mounted on the mounting seat 2 through a flange 4, and as shown in fig. 2, a pressed diaphragm 31 of the convex diaphragm type liquid level meter 3 is seen to extend into a tank body of the solvent receiving tank 1 through a cavity of the mounting seat 2.

By arranging the convex diaphragm type liquid level meter 3 at the bottom of the solvent receiving tank 1, the pressure diaphragm 31 is higher than the bottom of the solvent receiving tank 1 due to the height thereof, so that the material crystallization or precipitation formed on the surface of the pressure diaphragm 31 is avoided.

As a preferred technical scheme of the utility model, the bottom of the solvent receiving tank 1 is provided with a supporting part, the supporting part comprises more than three supporting legs 6 which are uniformly distributed, more preferably four supporting legs 6 are selected, the supporting effect is enhanced, the unstable fixation of the solvent receiving tank 1 is avoided, in addition, bolts can be arranged at the bottom of the supporting legs 6, and the supporting legs 6 are directly and fixedly connected with the ground; the support feet 6 enclose between them an accommodation space which is at least high enough to allow the mounting of the convex diaphragm type level gauge 3.
