Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a single-tube filtering structure based on a quick-install pipe fitting. Background Art

[0002] In the field of water treatment, various forms of filter systems are often needed, and there are three commonly used filter systems: plate filters, canister filters, and sleeve filters. Plate filters have limited pressure bearing capacity and low overall cost performance, and are generally used for special applications; sleeve filters have greater restrictions on filtration resistance and flow capacity, and in order to ensure the stability of the filtration effect, they usually use the same end inlet and outlet solution as canister filters.

[0003] In the prior art, both the sleeve-type and canister-type filters have a large overall diameter due to the built-in long tube, and the bearing pressure is limited. In addition, external piping is required for series connection during system assembly, which occupies a large space, is costly, and is relatively troublesome to load and replace the filter material. In this type of connection structure, because the inlet and outlet water of the filter are at the same end, that is, the water before and after treatment may be mixed, the stability of the water quality is poor during the filtration process of the filter material. Utility Model Content

[0004] The purpose of the utility model is to provide a single-tube filtering structure based on a quick-install pipe fitting to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a single-tube filtering structure based on quick-release pipe fittings, suitable for a pipe body, filter end pieces are arranged at both ends of the pipe body, and standard chucks are arranged on the filter end pieces and the pipe body for detachably connecting the filter end pieces to the pipe body and external pipe fittings, and a sealing gasket is arranged between the filter end pieces and the pipe body.

[0006] Preferably, the filter end piece is a tubular structure, an outer chuck is provided at one end of the filter end piece for connecting with an external pipe fitting, and a second sealing groove is provided on the outer chuck.

[0007] Preferably, a reverse chuck is arranged on one side of the outer chuck, the outer chuck and the reverse chuck are both standard chucks, and a transition section is arranged between the outer chuck and the reverse chuck.

[0008] Preferably, a third sealing groove is provided on a side of the reverse chuck away from the outer chuck.

[0009] Preferably, the reverse-mounted chuck is connected to a material-blocking cylinder, and a flow hole is provided in the material-blocking cylinder.

[0010] Preferably, a tapered portion is provided at the end of the material blocking cylinder.

[0011] Preferably, the tube body is filled with filter material, and the outer diameter of the material blocking cylinder is smaller than the inner diameter of the tube body by at least one filter material diameter.

[0013] Preferably, a pipe chuck is provided at the end of the pipe body, and the pipe chuck is a standard chuck.

[0014] Preferably, the pipe chuck is provided with a first sealing groove.

[0015] The single-tube filter structure based on quick-install pipe fittings has the following beneficial effects:

[0016] 1. The single-tube filter structure based on quick-install pipe fittings has a strong pressure-bearing body, which is the pipe body itself, and can be easily applied to the modification of existing pipe fittings or connected to the existing pipeline system because it uses a standard chuck for connection.

[0017] 2.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1 , Figure 7 As shown, the utility model provides a single-tube filtering structure based on quick-install pipe fittings, which is suitable for a pipe body 1. The pipe body 1 is filled with filter material 4 so that the internal space of the pipe body 1 can be used as the main working space of the filter. Filter end pieces 2 are arranged at both ends of the pipe body 1, and standard chucks are arranged on the filter end pieces 2 and the pipe body 1 for detachably connecting the filter end pieces 2 to the pipe body 1 and external pipe fittings.

[0029] Among them, Figure 2-Figure 3 As shown, a pipe chuck 11 is provided at the end of the pipe body 1 , and a first sealing groove 12 is provided in the pipe chuck 11 . The pipe chuck 11 is a standard chuck and can be matched and installed with the filter end piece 2 .

[0030] Specifically, Figure 2 , Figure 4-Figure 5 As shown, the filter end piece 2 is a tubular structure, and an outer chuck 21 is arranged at one end of the filter end piece 2 for connecting with an external pipe fitting. The outer chuck 21 has a second sealing groove 24, and the second sealing groove 24 can be adapted to the sealing structure (including but not limited to a sealing gasket and a sealing ring) on ​​the external pipe fitting to strengthen the sealing. A reverse chuck 23 is arranged on one side of the outer chuck 21, and a third sealing groove 28 is arranged on the side of the reverse chuck 23 away from the outer chuck 21 to strengthen the sealing when connected with the tube body 1. The outer chuck 21 and the reverse chuck 23 are both standard chucks.

[0031] Furthermore, a transition section 22 is provided between the outer chuck 21 and the reverse chuck 23, and the transition section 22 is used to separate the outer chuck 21 and the reverse chuck 23, so that there is enough working space for clamps or clamp-type locking parts when installed on external pipe fittings. The reverse chuck 23 is connected to a material blocking cylinder 25, and the outer diameter of the material blocking cylinder 25 is smaller than the inner diameter of the tube body 1 by at least one filter material 4 diameter. The material blocking cylinder 25 is provided with a flow hole 27, and the aperture size of the flow hole 27 is smaller than the particle size of the filter material 4 to prevent the filter material 4 from flowing out from the flow hole 27. A tapered portion 26 is provided at the end of the material blocking cylinder 25, so that the material blocking cylinder 25 can be more conveniently inserted into the interior of the tube body 1 during installation. The tapered portion 26 is a tapered structure, and is also distributed with flow holes 27 to increase the flow capacity of the overall structure, so that the flow of water is smoother.

[0032] It is understandable that the taper of the conical portion 26 is related to the amount of filter material 4 filled and the particle size of the filter material 4. When the particle size of the filter material 4 is small and the filling is sufficient, a larger taper is selected to facilitate the insertion and assembly operation after filling.

[0033] like Figure 6-Figure 8 As shown, a sealing gasket 3 is arranged between the filter end piece 2 and the tube body 1, and annular convex rings 31 are arranged on both sides of the sealing gasket 3, and the two convex rings 31 are symmetrically arranged, and the convex rings 31 are adapted to the first sealing groove 12 on the tube chuck 11, the third sealing groove 28 on the reverse chuck 23, and the second sealing groove 24 on the outer chuck 21, so as to realize reliable sealing of these components. In actual use, standard chucks all use the specifications of the sealing gasket 3 to unify the component composition.

[0034] In this embodiment, if Figure 7 As shown, after the water flows into the filter end piece 2 from one end, it comes into contact with the filter material 4 through the flow hole 27 of the retaining cylinder 25 set at one end. The filter material 4 filters the water flow. After passing through the entire tube body 1, the water flows out from the flow hole 27 of the retaining cylinder 25 at the other end, passes through the filter end piece 2, and enters the next process.

[0035] In the present application, the pipe body 1 is used as a quick-install pipe fitting structure commonly used in water treatment systems. The scheme involved in the present invention can quickly make modifications to add filtering based on the pipe body 1. It only needs to add filter end pieces 2 and corresponding sealing gaskets 3 at both ends of the pipe body 1, and fill filter material 4 in the pipe body 1, so that the pipe body 1 can be transformed from a flow-through component into a filtering device. The operation is simple and easy, and the process cost is low. The tapered portion 26 set at the end of the retaining cylinder 25 in the filter end piece 2 also takes into account the insertion and installation problem when the pipe body 1 is fully filled with filter material 4. The structure can flexibly select series connection and parallel connection according to space and filtering effect requirements. Considering the pressure loss related to the particle size and density of the filter material 4 in the pipe body 1, the filtering direction can be expanded in parallel according to the implementation situation. Because both ends of the pipe body 1 use a quick-install standard chuck structure (i.e., the pipe fitting chuck 11), the implementation is very convenient, and only requires fewer parts and space to reduce pressure loss while ensuring flow capacity.

[0036] In the present application, since the pressure-bearing main body is the pipe body 1 itself, the pressure-bearing capacity is strong, and a standard chuck is used for connection, it can be conveniently applied to the modification of existing pipe fittings or connected with an existing pipeline system.

[0037] In addition, the water flows unidirectionally along the axial direction of the tube body 1, so that the water before and after treatment cannot be mixed at the same end, thereby ensuring the effectiveness of a single filtration and making the water quality more stable.

[0038] Working principle: After the water flow before treatment enters the filter end piece 2 from one end, it comes into contact with the filter material 4 through the flow hole 27 of the material retaining cylinder 25 set at one end. The filter material 4 filters the water flow. After passing through the entire tube body 1, the water flow flows out from the flow hole 27 of the material retaining cylinder 25 at the other end. After the treated water flow passes through the filter end piece 2, it enters the next process.

[0039] In summary, although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
