Description

Technical Field

[0001] The utility model belongs to the technical field of water treatment systems, in particular to an anti-blocking type variable gap water cap. Background Art

[0002] The resin in the cation bed, anion bed and mixed bed of the water treatment ion exchange system often contains some small and broken resin particles. During the backwash process, the qualified resin is in the middle and lower part of the bed, and the small and broken resin particles will be adsorbed to the wire-wrapped water cap of the backwash pipe with the water flow. In order to prevent the resin from running out, the gap of the traditional water cap is small and the width of the gap is fixed. The small and broken resin will block the gap of the water cap, making the backwash flow smaller or even almost zero, thereby causing the equipment to be pressurized and the backwash effect is poor. Utility Model Content

[0003] The utility model overcomes the shortcomings of the prior art and proposes an anti-blocking type variable gap water cap, solving the problem of fine broken resin blocking the wire-wrapped water cap during the backwashing process.

[0004] In order to achieve the above purpose, the utility model is implemented through the following technical solutions.

[0005] A blocking-proof variable gap water cap, used in a water treatment ion exchange system containing resin particles, comprises a multi-section wire-wound filter cylinder, the multi-section wire-wound filter cylinders are connected in series in sequence through fixed sections to form a hollow water cap structure, one end of the water cap structure is connected to a water cap upper cover, and the other end of the water cap structure is connected to a water cap fixing part of a hollow structure; the wire-wound filter cylinder is formed by winding wires at a certain interval;

[0006] One end of the water cap structure connected to the water cap fixing piece extends into the backwash drainage pipe, and a fixing structure is provided at the end of the backwash drainage pipe, and the fixing structure is connected to the fixing joint to connect the water cap structure to the backwash drainage pipe;

[0007] The spacing of the wires on the multi-section wire-wound filter cylinder decreases successively from the water cap fixing part to the water cap upper cover, and the spacing of the wires on the wire-wound filter cylinder located outside the backwash drainage pipe is smaller than the particle size of the complete resin particles, and larger than the particle size of the broken small resins that need to be discharged.

[0008] Furthermore, an annular groove is provided on the fixing joint, and the fixing structure is an annular block protruding relative to the inner wall of the backwash drainage pipe, and the annular block is buckled in the groove.

[0009] Furthermore, the water cap upper cover has a closed spherical surface, and the water cap upper cover and the water cap lower cover are both sealed and connected to the water cap structure.

[0010] Furthermore, the wire-wound filter cylinder is welded to the fixed node.

[0011] Furthermore, the water cap fixing piece is connected to the adjacent wire-wound filter screen cylinder via a fixing node.

[0012] Furthermore, the winding wire is made of stainless steel.

[0013] The beneficial effects of the utility model compared with the prior art are:

[0014] The utility model has a variable gap water cap with a structure of various gap widths, which can be adjusted to a required gap width according to the resin particle size and fixed thereto. During the backwashing process, the fine and broken resin will be washed away from the corresponding gap with the water flow, thereby avoiding blockage.

[0015] The utility model solves the problem that the traditional wire-wound water cap of the ion exchanger in the water treatment system is easily blocked by fine broken resin during the backwash process. The fine broken resin flows out through the part where the gap width is larger than its particle size, and the qualified resin does not flow out, thereby achieving the best backwash effect of the resin.

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail in combination with the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. The technical solution of the present invention is described in detail below in combination with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0021] like Figure 1 and Figure 2 As shown, the present embodiment provides an anti-blocking variable gap water cap, comprising three sections of wire-wound filter cylinders 1, which are connected in series in sequence through fixed sections 2 to form a hollow water cap structure, one end of the water cap structure is connected to the water cap upper cover 3, and the other end of the water cap structure is connected to the hollow water cap fixing member 4; the water cap fixing member 4 is a hollow tube, and one end of the water cap structure connected to the water cap fixing member 4 extends into the backwash drainage pipe 7, and the water cap fixing member 4 is connected to the backwash drainage pipe 7; the water cap fixing member 4 is used to stabilize the overall structure of the water cap.

[0022] The wire-wound filter screen cylinder 1 is a cylindrical cavity structure formed by winding wires 6 made of stainless steel at a certain interval, and a certain gap is left between the wires 6 to allow water to flow through the gap.

[0023] A fixing structure 8 is provided at the end of the backwash drainage pipe 7 , and the fixing structure 8 is connected to the fixing section 2 so that the water cap structure is connected to the backwash drainage pipe 7 .

[0024] From the water cap fixing part 4 to the water cap upper cover 3, the spacing between the wire wraps 6 on the three-section wire wrap filter cylinder 1 decreases successively; the size of the spacing is set according to the resin particle size, so that the spacing between the wire wraps 6 on the wire wrap filter cylinder 1 located outside the backwash drainage pipe 7 is smaller than the particle size of the complete resin particles, and larger than the particle size of the broken small resin that needs to be discharged.

[0025] In this embodiment, the water cap structure is welded to the fixing section 2, and an annular groove is provided on the fixing section 2. The fixing structure 8 is an annular block protruding relative to the inner wall of the backwash drainage pipe 7, and the annular block is buckled in the groove.

[0026] In this embodiment, the water cap upper cover 3 has a closed spherical surface, and the water cap upper cover 3 is sealed and connected to the water cap structure. The water cap fixing member 4 is connected to the adjacent wire-wound filter screen cylinder 1 through a fixing section 2.

[0027] Working principle:

[0028] The variable gap water cap installed in the ion exchange system has one end of its water cap fixing part 4 extending into the backwash drainage pipe 7, and is connected by snapping with the annular clamping block on the backwash drainage pipe 7 through the annular clamping groove on the outer wall of the fixing section 2. The wire-wound filter cylinder 1 located in the middle is arranged outside the backwash drainage pipe 7, and the spacing between the wires 6 on the middle wire-wound filter cylinder 1 is smaller than the particle size of the complete resin particles, and larger than the particle size of the broken small resins to be discharged. The water with the fine broken resin flows from the side wall of the middle wire-wound filter cylinder 1 through the gaps between the wires 6 directly from the overall hollow structure into the backwash drainage pipe 7; and then is discharged from the equipment through the backwash drainage pipe 7. In this process, the fine broken resin flows out through the gaps between the wires 6 of the middle wire-wound filter cylinder 1, and the qualified resin does not flow out, which solves the problem of the water cap being blocked by the broken small resin.

[0029] The water cap structure connected to the multi-section wire-wound filter cylinder 1 can also be connected at an appropriate position according to actual conditions to be suitable for resin environments with various particle sizes.

[0030] The above content is a further detailed description of the utility model in combination with a specific preferred implementation method. It cannot be determined that the specific implementation methods of the utility model are limited to this. For ordinary technicians in the technical field to which the utility model belongs, they can make several simple deductions or substitutions without departing from the utility model, which should be regarded as belonging to the utility model and the scope of patent protection determined by the submitted claims.
