Description

Technical Field

[0001] This utility model relates to the field of filter device technology, and more specifically, to a dual-phase steel water distribution device for a fiberglass activated carbon filter. Background Technology

[0002] In the field of seawater desalination, fiberglass activated carbon filters are used because the high salinity of seawater makes it impossible to use activated carbon filters made of conventional materials, and the cost of using full duplex steel tanks is too high.

[0003] Traditional water distributors are mostly made of PVC material. PVC material is not resistant to high temperatures, which makes it impossible for the activated carbon in the fiberglass activated carbon filter to be disinfected and regenerated at high temperatures. When the activated carbon is saturated, it can only be replaced as a whole, which increases production costs. In addition, traditional water distributors generally do not have a water distributor on the top, resulting in uneven water intake and easily disturbing the filter layer.

[0004] Therefore, we have made improvements to this and proposed a dual-phase steel water distribution device for a fiberglass activated carbon filter. Utility Model Content

[0005] The purpose of this utility model is that water distributors are mostly made of PVC material, which is not resistant to high temperature. This makes it impossible for the activated carbon in the fiberglass activated carbon filter to be disinfected and regenerated at high temperature. When the activated carbon is saturated, it can only be replaced as a whole, which increases the production cost. In addition, traditional water distributors generally do not have a water distributor on the top, which leads to uneven water intake and easily disturbs the filter layer.

[0010] To achieve the above technical solution, the water distributor assembly is rotated intermittently by an intermittent mechanism, so that the water sprayed from the water distribution pipe can evenly cover all areas inside the filter tank, avoiding uneven water distribution in some areas, effectively improving the filtration effect, and ensuring that the activated carbon in the entire filtration area can fully exert its adsorption function.

[0011] As a preferred embodiment of the dual-phase steel water distribution device for the fiberglass activated carbon filter provided by this utility model, the water distributor assembly includes a water distribution shell installed on the inner wall of the filter tank, a plurality of connecting shells installed on the outer side of the water distribution shell, a tapered connector slidingly and elastically fitted on one side of the inner wall of the connecting shell, a water distribution pipe slidingly fitted on the inner wall of the connecting shell, an L-shaped snap-fit ​​ring groove opened on both sides of the inner wall of the connecting shell, and a limit sliding rod fixedly connected to both sides of the water distribution pipe.

Compared with traditional PVC water distributors, it can withstand the high temperature environment during hot water disinfection and regeneration, and is not easily damaged under complex water quality conditions such as seawater desalination. This greatly extends the service life of the water distribution device and reduces equipment maintenance costs. The connecting shell of the water distributor component and the water distribution pipe are connected by an L-shaped snap-fit ​​ring groove and a limiting slide bar, which makes installation and disassembly convenient and facilitates daily maintenance of the equipment.

By setting an intermittent mechanism, the water distributor components are driven to rotate intermittently, making the water distribution more uniform. This reduces the problems of poor water distribution and uneven water intake that can disrupt the filter layer, which are common with traditional water distributors. At the same time, the water distributor made of duplex steel is resistant to high temperatures and corrosion, avoiding the problems of PVC water distributors being unable to withstand high temperatures and being easily deformed and damaged. This enables the activated carbon to be sterilized and regenerated through hot water circulation, reducing production costs. The device has a reasonable structural design, making it easy to maintain. The top water distributor can also prevent carbon loss during backwashing, thus improving the performance of the fiberglass activated carbon filter. Attached Figure Description

[0039] Please refer to Figures 1-5 A dual-phase steel water distribution device for a fiberglass activated carbon filter includes: a filter tank 1 with a slag discharge pipe 2 installed on one side; water distributor assemblies 3 are installed on both sides of the inner wall of the filter tank 1; a mounting frame 4 is fixedly connected to the upper side of the inner wall of the filter tank 1; an intermittent mechanism 5 cooperating with the water distributor assembly 3 is provided on one side of the mounting frame 4; an upper water inlet pipe 6 is fixedly connected to one side of the filter tank 1; a rotary joint 7 is installed at one end of the upper water inlet pipe 6; a lower water inlet pipe 8 is installed on one side of the filter tank 1 below the upper water inlet pipe 6; a control valve 9 is installed at one end of both the upper water inlet pipe 6 and the lower water inlet pipe 8; and a feed gate 10 is installed on the upper side of the filter tank 1. When the device is in operation, water can be introduced through the upper water inlet pipe 6 or the lower water inlet pipe 8 according to actual needs. When the upper water inlet pipe 6 is opened, water enters the top water distribution shell 31 through the rotary joint 7. The rotary joint 7 ensures that the water distribution shell 31 can stably receive water during rotation. If the lower water inlet pipe 8 is opened, water directly enters the corresponding water distribution shell 31. The water entering the water distribution shell 31 will flow into multiple connecting shells 32 on the outside. Under the action of the spring, the conical connector 33 squeezes against the water distribution pipe 34. The two are tightly connected, and the water smoothly enters the water distribution pipe 34. Then, the water distribution pipe 34 evenly distributes the water into the filter tank 1. With the cooperation of the L-shaped snap ring groove 35 and the limiting slide rod 36, the conical connector 33 is tightly connected to the water distribution pipe 34, which facilitates the disassembly and replacement of the water distribution pipe 34.

[0040] Please refer to Figure 2 - Figure 4The water distributor assembly 3 (made of duplex steel, possessing excellent high-temperature and corrosion resistance) includes a water distribution shell 31 installed on the inner wall of the filter tank 1. Multiple connecting shells 32 are installed on the outer side of the water distribution shell 31. A tapered connector 33 slides and elastically engages on one side of the inner wall of each connecting shell 32. A water distribution pipe 34 slides on the inner wall of the connecting shell 32. L-shaped snap-fit ​​grooves 35 are formed on both sides of the inner wall of the connecting shell 32. Limiting slide rods 36 are fixedly connected to both sides of the water distribution pipe 34. The limiting slide rods 36 slide on the inner wall of the L-shaped snap-fit ​​grooves 35, and the tapered connectors 33 engage with the water distribution pipe 34. The water distributor assembly 3 is made of duplex steel. The upper side of the water distribution shell 31, located at the top, rotatably engages with the inner wall of the rotary joint 7 via a connecting pipe. The intermittent mechanism 5 includes a ratchet disc 51 rotatably fitted on one side of the mounting frame 4. A transmission plate 52 is rotatably fitted on one side of the mounting frame 4. One end of the transmission plate 52 is rotatably fitted with a pawl 53. A drive motor 54 is mounted on the upper side of the filter tank 1. A rotating shaft 55 is fixedly connected to the output end of the drive motor 54. A pressing cam 56 is fixedly connected to the lower end of the rotating shaft 55. A rotating wheel 57 is rotatably fitted to the other end of the transmission plate 52. A tension spring 58 is provided between the transmission plate 52 and the mounting frame 4. The ratchet disc 51 and the pawl 53 cooperate. The two ends of the tension spring 58 are fixedly connected to the mounting frame 4 and the transmission plate 52, respectively. The pressing cam 56 contacts the rotating wheel 57. A water distribution shell 31 provided at the top is fixedly connected to the lower side of the ratchet disc 51. The drive motor 54 on the upper side of the filter tank 1 starts, driving the rotating shaft 55 to rotate. The pressing cam 56 at the lower end of the rotating shaft 55 rotates accordingly, and the pressing cam 56 contacts the rotating wheel 57. During the rotation, it periodically presses the rotating wheel 57. The rotating wheel 57 drives the transmission plate 52 to rotate around its rotation point with the mounting bracket 4. The pawl 53 at one end of the transmission plate 52, under the action of the tension spring 58, always maintains a tendency to clamp onto the ratchet disc 51. When the transmission plate 52 rotates, the pawl 53 intermittently engages with the tooth groove of the ratchet disc 51, driving the ratchet disc 51 to rotate. Due to the top... The water distribution shell 31 is fixedly connected to the lower side of the ratchet disc 51, so the water distribution shell 31 will rotate intermittently, thereby causing the water distributor assembly 3 to rotate intermittently, making the water distribution more uniform. When the activated carbon in the filter tank 1 is disinfected and regenerated with hot water, the water inlet method can be controlled to make the hot water circulate in the filter tank 1 to disinfect and regenerate the activated carbon. When the filter is backwashed, the water distribution device is also used to make the backwash water evenly distributed. The top water distribution device prevents the loss of activated carbon. During normal production, the upper and lower water distributors work together to ensure that the inlet and outlet water are uniform and do not disturb the filter layer.

[0041] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
