Description

Technical Field

[0001] This invention relates to the field of water purification equipment, specifically a water distributor on a molecular sieve. Background Technology

[0002] "Water distribution" refers to the arrangement of water volume according to a certain pattern on a certain working area. It is commonly used to evenly distribute water on the working surface. The device that accomplishes this task is called a water distributor. Water distributors are usually used in mechanical filtration equipment, activated carbon filtration equipment, water softening treatment equipment, and demineralized water equipment. They can also be used in various valveless filter tanks, bottom filter screens of mixing tanks, etc.

[0003] Currently, top water distributors are mainly installed inside water treatment equipment. Their function is to evenly distribute water flow and prevent filter media loss. In order to ensure uniform water distribution in water treatment equipment, they are usually used in conjunction with fiberglass water treatment tanks and suitable water distributors to collect and distribute water. However, the existing top water distributors generally use fixed specifications for the branch pipe drainage holes. This means that when the influent flow changes, the fixed flow rate of the distributor branch pipe cannot match the corresponding water flow, which can easily lead to reduced resistance in the top water distributor, resulting in insufficient pressure and reduced water production. Summary of the Invention

[0004] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a water distributor on a molecular sieve. By supporting the elastic tube and the swing clamp in the process of use, the water distribution tube can be adjusted according to different usage requirements. At the same time, when the inlet water flow changes, the inner adjusting tube nested on the outer tube can be adjusted.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a molecular sieve upper water distributor, comprising a fiberglass resin tank, a tank body being disposed within the fiberglass resin tank, a molecular sieve storage tray being formed on the upper part of the tank body, an upper water distributor being installed above the molecular sieve storage tray, a lower water distributor being disposed below the molecular sieve storage tray, a water distributor base being disposed within the upper water distributor, a connecting sleeve being connected to the water distributor base, a connecting flange for fixing being disposed at the top of the connecting sleeve, an outer sleeve being disposed within the water distributor base, and an inner connecting water distribution platform for uniform water distribution being connected below the outer sleeve; a uniform distribution platform being disposed within the inner connecting water distribution platform, a water guide hole for diversion being opened on the inner wall of the uniform distribution platform, and a plurality of connecting flexible oscillating tubes being disposed on the outer surface of the uniform distribution platform, one end of each connecting flexible oscillating tube being connected to a water distribution pipe. The connecting flexible pipe is mainly used for connecting water distribution pipes. When adjusting the angle, the connecting flexible pipe can play an auxiliary stretching and expansion role, so that the water distribution pipe will not be restricted when changing the angle.

[0007] A further improvement to the invention is that an outer sleeve is provided inside the water distribution pipe. The surface of the outer sleeve has through grooves, and one end of the outer sleeve has a connecting hole. An adjustable inner sleeve is nested inside the outer sleeve. The plurality of through grooves on the outer sleeve, in conjunction with the adjustable inner sleeve, form a layered, staggered design. This allows the adjustable inner sleeve to be rotated according to different flow rates, thereby changing the size of the openings within its through grooves and better matching the flow rate.

[0008] A further improvement to the invention is that a torsion cap is provided inside the adjusting inner tube, and a rubber pad of the same size is provided on the lower surface of the torsion cap. An auxiliary connecting pipe is installed in the center of the torsion cap, and a fixing strip is installed at the end of the auxiliary connecting pipe. Large-diameter drainage strips and small-diameter drainage strips are alternately installed on the fixing strip. Auxiliary rotating rings are provided at the ends of the large-diameter and small-diameter drainage strips. The large-diameter and small-diameter drainage strips are installed alternately, with a fixing strip for connection at one end and an auxiliary rotating ring for assisting rotation and fixation at the other end. Each time the large or small-diameter drainage strip is replaced, the diameter of the other inner grooves changes synchronously.

[0009] A further improvement to the invention is that the auxiliary rotating ring is connected to the inside of the outer sleeve, the connecting hole is connected to the connecting flexible swing tube via a thread, and either the large-diameter drainage strip or the small-diameter drainage strip can mate with the through groove. The rubber pad is disposed between the outer sleeve and the torsion cap. The auxiliary rotating ring is mainly used to cooperate with the outer sleeve for nested rotation, thereby driving the large-diameter or small-diameter drainage strip to move, continuously rotating clockwise or counterclockwise, aligning the large-diameter or small-diameter drainage strip directly with the center of the through groove to achieve uniform water distribution.

[0010] A further improvement to the present invention is that a tube body is provided inside the outer sleeve, and an embedded groove is formed inside the tube body. A plurality of auxiliary locking grooves are formed on the surface of the embedded groove, and side wing locking grooves are formed on both outer surfaces of the tube body. The side wing locking grooves are mainly used to connect and fix the tube body, so that the tube body can move in conjunction with the clamping of the side wing locking grooves, thereby changing the cleaning angle of the tube body and completing the corresponding angle adjustment.

[0011] A further improvement to the invention is that the size of the embedded groove is adapted to the size of the auxiliary rotating ring, the inner groove of the auxiliary clip engages with the rubber ball provided on the surface of the auxiliary rotating ring, one end of the tube is threadedly connected to the connecting flexible swing tube, and the other end of the tube engages with the torsion cap. The torsion cap connected to the other end of the tube mainly serves to adjust the hollow part inside the tube, thereby adjusting the connected auxiliary tube and fixing strip accordingly, thus completing the conversion of the diameter with the cooperation of the torsion cap.

[0012] A further improvement to the present invention is that an annular cylinder is provided inside the uniformly distributed platform, and a complex set of swing clamps is installed on the side wall of the annular cylinder. Each swing clamp is connected to a supporting elastic tube at its upper and lower ends, and the bottom plate of the annular cylinder has an auxiliary support plate. The mutually supporting swing clamps on the annular cylinder are connected by a central rotating shaft, and then the supporting elastic tubes are connected to the outer surface of the swing clamps, so that the tilt angle can be manually adjusted after connection, and the clamp can be fixed at the adjusted angle.

[0013] A further improvement to the invention is that one end of the elastic tube is installed on the outer surface of the distribution platform, and the upper part of the distribution platform is connected to the outer sleeve. The outer sleeve is connected to the connecting sleeve by a screw, and the connecting flange is fixed to the outer surface of the fiberglass resin tank. The connecting flange is mainly fixed to the outer surface of the fiberglass resin tank, thereby allowing the water distributor to be placed inside the fiberglass resin tank, forming a seal while maintaining its position, thus completing the water distribution work.

[0014] A further improvement to the present invention is that the bottom of the fiberglass resin tank is connected to several support members for support, and support flanges are installed at both the top and bottom of the fiberglass resin tank. The support members connected to the bottom of the fiberglass resin tank are mainly used to suspend the fiberglass resin tank and support it to ensure that the fiberglass resin tank can be placed stably. Beneficial effects

[0015] Compared with the prior art, the present invention has the following beneficial effects;

[0016] 1. This invention, through the cooperation between the support elastic tube and the swing clamp during use, allows the water distribution pipe to be adjusted according to different usage requirements. At the same time, when the inlet water flow changes, the inner adjusting tube nested on the outer sleeve can be adjusted to change the position of the large-diameter or small-diameter drainage strip on the through groove, so as to adapt to different flow outputs and avoid insufficient pressure, resulting in reduced water production.

[0017] 2. In the process of use, the present invention allows for the adjustment of the angle of the water distribution pipe clamped between the swing clamps according to the needs of use. When upward movement is required, the swing clamps are hinged to the ring cylinder, causing the lower supporting elastic tube to be stretched and the upper supporting elastic tube to be contracted. This allows the water distribution pipe to be adjusted in angle during actual use, thereby better completing the work of the water distributor. Attached Figure Description

[0032] The present invention will be further described below with reference to the accompanying drawings: Example 1

[0033] As attached Figures 1 to 5 , Figure 7 , Figure 8 , Figure 9 As shown:

[0034] This embodiment provides a molecular sieve upper water distributor, including a fiberglass resin tank 1. Several support members 3 are connected to the bottom of the fiberglass resin tank 1 for support. Support flanges 2 are installed at both the top and bottom of the fiberglass resin tank 1. A tank body 11 is provided inside the fiberglass resin tank 1. A molecular sieve storage tray 13 is formed inside the tank body 11. An upper water distributor 12 is installed above the molecular sieve storage tray 13, and a lower water distributor 14 is provided below the molecular sieve storage tray 13. A water distributor base 121 is provided inside the upper water distributor 12. A connecting sleeve 122 is connected to the water distributor base 121. A connecting flange 123 for fixing is provided at the top of the connecting sleeve 122. An outer sleeve 1211 is provided inside the water distributor base 121. Below the outer sleeve 1211, there is an inner connecting water distribution platform 1212 for uniform water distribution; inside the inner connecting water distribution platform 1212, there is a uniform distribution platform 12121, and the inner wall of the uniform distribution platform 12121 is provided with a water guide hole 12122 for diversion. The outer surface of the uniform distribution platform 12121 is provided with a plurality of connecting flexible swing tubes 12123. One end of the connecting flexible swing tube 12123 is connected to a water distribution pipe 12124. The water distribution pipe 12124 is provided with an outer sleeve 121242. The surface of the outer sleeve 121242 is provided with a through groove 121243. One end of the outer sleeve 121242 is provided with a connection hole 121244. An adjustable adjustment inner tube 121241 is nested inside the outer sleeve 121242.

[0035] The inner adjusting tube 121241 is equipped with a torsion cap 1212411. The lower surface of the torsion cap 1212411 is equipped with a rubber pad 1212412 of the same size. An auxiliary connecting tube 1212413 is installed in the center of the torsion cap 1212411. A fixing strip disc 1212414 is installed at the end of the auxiliary connecting tube 1212413. Large-diameter drainage strips 1212415 and small-diameter drainage strips 1212416 are installed alternately on the fixing strip disc 1212414. Auxiliary rotating rings 1212417 are provided at the ends of the large-diameter drainage strips 1212415 and the small-diameter drainage strips 1212416.

[0036] The outer tube 121242 contains a tube body 1212421, the tube body 1212421 contains an inner groove 1212423, the inner groove 1212423 contains a plurality of auxiliary card grooves 1212424, and the outer surfaces of both sides of the tube body 1212421 contain side wing slots 1212422.

[0037] Furthermore, the connecting sleeve 122 is connected to the water distributor base 121 by threads, and a connecting flange 123 is connected to the top. By setting the connecting flange 123 on the top of the fiberglass resin tank 1 and fixing it with the flange on the fiberglass resin tank 1 by bolts, the fiberglass resin tank 1 is sealed and closed.

[0038] Furthermore, the inner water distribution platform 1212 is mainly connected through the outer sleeve 1211 to ensure that the water source entering from the outside is collected on the inner water distribution platform 1212, and then distributed by the water distribution pipe 12124 through the water guide hole 12122 opened on the inner wall of the inner distribution platform 12121.

[0039] Furthermore, the inner sleeve 121242 is hollowed out and forms a partition with the through groove 121243, so that after the inner adjusting tube 121241 is inserted, the hollowed-out state and the through groove 121243 are used to adapt to the large-diameter drainage strip 1212415 and the small-diameter drainage strip 1212416 to complete the flow adjustment.

[0040] The specific working principle is as follows:

[0041] This invention supports the fiberglass resin tank 1 using a support member 3. A support flange 2, installed at the center of the top or bottom of the fiberglass resin tank 1, connects to the upper water distributor 12 or the lower water distributor 14. The molecular sieve is then placed in the molecular sieve storage tray 13 to assist in water purification. During installation, the water distributor base 121 is first placed in, and then the water distribution pipes 12124 on the inner connecting water distribution platform 1212 are installed one by one. Simultaneously, the connecting flexible oscillating pipes 12123 are screwed onto them at designated positions, thereby connecting the water distribution pipes 12124 to the connecting flexible oscillating pipes 12123. The upper part supports the swing clamp 121212 by supporting the elastic tube 121213, thereby fixing the tube body 1212421 and securing it to the side wing slot 1212422. When the flow rate needs to be adjusted, the torsion cap 1212411 is rotated, thereby driving the auxiliary tube 1212413 to cooperate with the large-diameter drainage strip 1212415 or small-diameter 1212416 on the fixed strip plate 1212414 for adjustment. Finally, it is set on the through groove 121243 to evenly distribute water to the molecular sieve storage plate 13 below. Example 2

[0042] As attached Figure 6 As shown:

[0043] The uniform distribution platform 12121 is equipped with an annular cylinder 121211. The side wall of the annular cylinder 121211 is equipped with multiple swing clamps 121212. The swing clamps 121212 are connected to the upper and lower parts by support elastic tubes 121213. The bottom plate of the annular cylinder 121211 has an auxiliary support plate 121214.

[0044] Furthermore, the outer surface of the ring cylinder 121211 is provided with at least 6 protrusions, and a through rotating shaft is installed between each protrusion. A swing clamp 121212 is fixed on the rotating shaft. The swing clamp 121212 cooperates with the support elastic tube 121213 to complete the corresponding force on the swing clamp 121212, so that the swing clamp 121212 is subjected to clamping pressure and positioning after swinging, ensuring the angular stability of the tube 1212421.

[0045] Furthermore, the support elastic tube 121213 mainly completes the folding and positioning by cooperating with the outer folding rubber sleeve and the built-in elastic element, so that it remains fixed after compression and folding, and will not cause the tube body to change in angle adjustment.

[0046] The specific working principle is as follows:

[0047] This invention connects the annular cylinder 121211 with the upper outer sleeve 1211, and the connecting sleeve 122 with the connecting flange 123. The supporting elastic tube 121213 is disposed between the protrusions on the outer surface of the annular cylinder 121211. After being threaded, the tube 1212421 is clamped and fixed with the swing clamps 121212 on both sides. The swing clamps 121212 are positioned by the supporting elastic tube 121213 at both the top and bottom, thereby preventing the angle of the tube 1212421 from changing after the swing clamps 121212 swing. The auxiliary support plate 121214 is used to support the bottom of the elastic tube 121213. One end of the top supporting elastic tube 121213 is fixed to the surface of the annular cylinder 121211 to ensure that the tube is positioned after the angle swing, which facilitates the replacement of the tube 1212421 for water distribution after the angle adjustment.
