Abstract

The utility model relates to a float top water tank which solves the problem of enhancing floating top performance. The float top water tank comprises a water tank body, an upper cover, a lower bottom and necessary devices arranged on the lower bottom, and also comprises a float top as a covering device for the liquid level in the water tank body. A water inlet is positioned below float top which is composed of a lower pressure ring, a float ring, a middle pressure ring, thin films, a rubber ring, an upper pressure ring and fixtures thereof, and the thin films and the rubber ring are positioned between the middle and the upper pressure rings. The utility model is characterized in that through holes which are extended downward with guide tubes are arranged in areas of the thin films without float blocks. The utility model is used for containing high purity water, etc.

Description

Float top water tank

The utility model relates to water tank, refers in particular to a kind of water tank that has floating top that stores high purity water.

Existing Float top water tank such as Fig. 1,2, it is a container, comprises loam cake 1, goes to the bottom 2, and devices such as manhole 3,4, liquid level alarm 5, bleed off pipe 6, blow-off pipe 7 are arranged, as the water tank that stores high purity water, there is a reasonable floating top E of liquid level coverage scale its inside.Water inlet 8 is located at the bottom of water tank, promptly below floating top E.This floating top E is as the liquid level cladding system, and shown in Fig. 3,4,5, Fig. 4 is the upward view of Fig. 3, and Fig. 5 is the F partial enlarged drawing of Fig. 3; Pressure ring 9, floating ring 10, middle pressure ring 11, film 12, rubber grommet 13 and upper press ring 14 under it is constructed and is from bottom to top; Be that film 12 is loaded into one with rubber grommet 13 mat bolts 15, packing ring 16, nut 17, the external diameter of rubber grommet 13 is slightly larger than inside diameter of vessel, make it both closely connected container inner wall, floating top E is slided up and down with liquid level change, wherein, below film 12, be fixed with floating block 18, so that hold film 12, but find that in actual use one of its shortcoming is can produce hydrops and sink in A, the B of the not cloth floating block 18 of film 12, C, D zone, influences service property (quality); Two of shortcoming be in being in the film 12 of 13 of pressure ring 11 and rubber grommets can string to take place moving, to cause film 12 destroyed; Three of shortcoming is because middle pressure ring 11, the internal diameter of upper press ring 14 and the internal diameter of rubber grommet 13 all equate, be the seamed edge angle that has rigidity around them, thorn touches film 12 and it is damaged easily, causes shorten the application life of floating top E, bring the trouble of maintenance, influence the use of whole Float top water tank.

The purpose of this utility model provides a kind of Float top water tank with the floating top of better performance.

The purpose of this utility model is achieved in that Float top water tank, and it comprises tank body, loam cake, goes to the bottom and set thereon necessary device; Also comprise the floating top as the liquid level cladding system in the tank body, water inlet is positioned at below, floating top; Floating top is for pressure ring, floating ring, middle pressure ring, film, rubber grommet, upper press ring and fixture thereof are formed down, film, rubber grommet is characterized in that between middle pressure ring and upper press ring: do not offer through hole in the zone, floating block place and extended conduit downwards in through hole being furnished with of film.

Above-mentioned design remains in coverage scale under 98% the preceding topic, has both prevented the pollution of pernicious gas to water liquid, has reached again to avoid the film hydrops, reduce the effect that film damages.

Below by drawings and Examples the utility model is described further again.

Fig. 1,2 is existing Float top water tank schematic diagram;

Fig. 3,4,5 is the floating top of existing Float top water tank organigram;

Fig. 6 is the floating top organigram of the utility model Float top water tank;

Fig. 7 is Fig. 6 upward view;

Fig. 8 is the local G structure for amplifying of a Fig. 6 schematic diagram;

Fig. 9 analyses and observe amplification for the local H of Fig. 7 place side and shows that through hole 19 has extended conduit 20 schematic diagrames downwards;

Figure 10 is one of the floating conduit embodiment that pushes up of the utility model organigram;

Figure 11～12 are two organigrams of the conduit embodiment on the floating top of the utility model;

Figure 13～14 are three organigrams of the conduit embodiment on the floating top of the utility model;

Figure 15 is four organigrams of the conduit embodiment on the floating top of the utility model.

Figure 16 establishes the hole and extends the schematic diagram of blowdown with guiding tube downwards for the utility model in floating top film central authorities.

Shown in Fig. 6～9: the floating top structure of the utility model Float top water tank be at film 12 the A that is not furnished with floating block 18 places, B, C, D zone is well-regulated is provided with equally spaced a plurality of through hole 19, and has extended conduit 20 downwards in through hole 19.As seen from Figure 8, also be provided with the rubber grommet 21 that its external diameter is slightly larger than inside diameter of vessel between the middle pressure ring 11 of the floating top of the utility model E and the film 12.Middle pressure ring 11 by rigidity when preventing that film 12 string is moving is damaged; And the internal diameter of rubber grommet 21 that also can establish the internal diameter of rubber grommet 13 on film 12 upper stratas and film 12 lower floors is all greater than the internal diameter of middle pressure ring 11 and upper press ring 14; The unlikely direct contact membrane 12 of inner frieze corner angle of pressure ring 11, upper press ring 14 is protected and unlikely being damaged film 12 in making.

As shown in figure 10: conduit 20 lower ends are reducing and are provided with in reducing place and take over 26.

Shown in Figure 11,12: conduit 20 lower end inwalls are established hard sleeve 22.

Shown in Figure 13,14: conduit 20 lower end inwalls are established two sleeve pipes 23.

As shown in figure 15: outer tube 24 is established in conduit 20 lower ends.

As shown in figure 16: establish blowdown with guiding tube 25 in floating top film 12 central authorities.

Nationality guiding tube 25 is to the bottom of water tank or the 2 connection blow-off pipes 7 of going to the bottom thus, can be in order to flushing film 12 surface irregularities, thereby control the cleaning on film 12 surfaces effectively, helping in the water tank medium can be not therefore and contaminated, the said water tank of the utility model, in fact, its essential structure is equally applicable to store other liquid mediums.All belong within the utility model scope of patent protection.
