Description

Technical Field

[0001] The utility model relates to the technical field of fire sprinkler heads, and more specifically to a self-cleaning sealed dustproof concealed sprinkler head. Background Art

[0002] Concealed sprinkler, generally composed of glass ball sprinkler, screw sleeve seat, outer cover seat, outer cover cover, screw sleeve seat, outer cover seat and outer cover cover after the concealed cover covers the glass ball sprinkler, improve the appearance, to provide a shielding type sealing and dustproof effect (such as the public (publication) number: CN207356435U, a concealed fire sprinkler) as shown;

[0003] The existing (publication (announcement) number: CN219251516U, a nozzle for an automatic fire sprinkler system) uses a "first filter plate and a second filter plate" to filter impurities, but the fire sprinkler is generally left unused for a long time. At this time, calcium and magnesium ions in the water will precipitate, and fine particles will be deposited in the small holes of the sprinkler to form scale, so there is still a problem that the sprinkler is easy to cause the nozzle hole to be blocked.

DETAILED DESCRIPTION Embodiment 1:

[0017] like Figure 1 As shown, this embodiment proposes: a self-cleaning sealed dustproof concealed sprinkler, comprising a sprinkler body 1 (as shown in the figure, it can be installed in a downward spraying style, and is a glass ball type fire sprinkler);

[0018] The nozzle body 1 is provided with a water passage cavity 11 and a water outlet 12 which are connected up and down (as shown in the figure, the water passage cavity 11 and the water outlet 12 are arranged inside the water receiving portion corresponding to the installation position);

[0019] The inner wall of the water outlet 12 is sealed with a water blocking plug 13 to close the water outlet 12 (the closed part is as shown in FIG. Figure 1 As shown, it is equivalent to the "glass body, clamping block, and clamping thread segment" components that can be used in the background technology "CN207356435U");

[0020] The top of the water passage cavity 11 is connected to the outside of the nozzle body 1 (such as Figure 1 As shown, the outer side of the water passage cavity 11 is in the shape of a threaded tube for installing water);

[0021] The top of the water passage cavity 11 is connected to a ring groove 14, and a filter plate 15 (such as Figure 1 As shown, the annular groove 14 is located at the top of the nozzle body 1 and is connected to the water passage cavity 11 to support the filter plate 15 so as not to fall into the water passage cavity 11). The filter plate 15 is used to filter impurities when water is passed into the water passage cavity 11.

[0022] The water passage cavity 11 is provided with an adsorption component 16 for reducing the hardness of water and adsorbing tiny particles, which can inhibit scale formation between the water blocking plug 13 and the water outlet 12, reduce the possibility of clogging the water outlet 12, and have high safety.

[0023] The nozzle body 1 is provided with a concealed cover body 2 to form a concealed nozzle (the concealed cover body 2 is equivalent to the "cover shell, nozzle body, decorative plate" in the background technology "CN207356435U", which covers the nozzle body 1 to provide a shielding-type sealed and dustproof effect);

[0024] The processing end of the adsorption component 16 is close to the water outlet 12, and water treatment can be carried out in a targeted manner at a position adjacent to the water blocking plug 13 and the water outlet 12, with good effect.

[0025] The adsorption component 16 does not cut off the flow cross section of the water passage cavity 11. Figure 1 As shown, the adsorption assembly 16 is in a ring shape, that is, it has a ring-shaped passing space, does not produce a truncated treatment, and has a good water flow smoothness.

[0026] In order to implement the above-mentioned adsorption component 16, it is proposed that Figure 1 As shown, the specific structure and composition of the adsorption component 16 can be as follows: the adsorption component 16 includes a guide ring cavity 161 that is expanded and connected in the water-passing cavity 11 and is connected to the annular groove 14 (as shown in the figure, the inner wall of the water-passing cavity 11 is expanded and enlarged by one circle to form the guide ring cavity 161, and the top of the guide ring cavity 161 is connected to the annular groove 14);

[0027] An annular frame 162 (in a ring shape, corresponding to the flow cross section of the adsorption component 16 not blocking the water passage cavity 11) is movable in the guide ring cavity 161. According to the above, the guide ring cavity 161 is not directly connected to the water outlet 12. In order to support the built-in setting of the annular frame 162 (such as Figure 1 As shown, in order to correspond to the processing end of the above-mentioned adsorption component 16 being close to the water outlet 12, that is, the annular frame 162 is arranged close to the water outlet 12);

[0028] A material cavity for arranging a filler layer 163 is provided in the annular frame 162. The filler layer 163 is an ion exchange resin and an activated carbon layer (which may be ion exchange resin particles and activated carbon particles);

[0029] The ion exchange resin is a high molecular polymer containing dissociable active groups. According to the different active groups, ion exchange resins can be divided into cation exchange resins (such as sulfonic acid resins) and anion exchange resins (such as quaternary ammonium resins). In the water treatment process, ion exchange resins can selectively exchange with cations or anions in the solution, so as to achieve the purpose of purifying water, softening hard water or extracting specific ions. For example, in the preparation of industrial pure water, ion exchange resins are often used to remove calcium and magnesium ions in water (softening water). In the treatment of heavy metal wastewater, they can be used to recover heavy metal ions, etc.

[0030] The activated carbon is a porous material made by high-temperature pyrolysis and activation of carbon-containing substances. It has a highly developed pore structure and a huge specific surface area. The activated carbon mainly removes fine impurities in water by physical adsorption.

[0031] A through hole 164 communicating with the material chamber is provided on the outside of the annular frame 162, so as to allow the filler layer 163 to contact with the water on the outside for treatment.

[0032] The through holes 164 are provided in a plurality of groups and are evenly distributed outside the annular frame 162 (as shown in the figure, the plurality of through holes 164 are evenly provided to improve the processing efficiency). Embodiment 2:

[0033] like Figure 1 As shown, the difference between the embodiment 1 and the embodiment 1 is that the adsorption assembly 16 further includes a connecting frame 165 (such as Figure 1 As shown, the connecting frame 165 can be a connecting rod set on the left and right sides of the top of the annular frame 162), and is set in an integrated manner, so that when the filter plate 15 is removed, the adsorption component 16 can be disassembled and assembled in an integrated manner, which is convenient to operate; and the overall stability will also be better.

[0034] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0035] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
