Description

Technical Field

[0001] This invention relates to the field of water purification, specifically to a water purification device for a direct drinking water system. Background Technology

[0002] Direct drinking water refers to water that meets the World Health Organization's standards for direct consumption. In a direct drinking water system, water is purified using water purification equipment to meet these standards. The water purification equipment in a direct drinking water system typically employs multiple purification methods, including but not limited to multi-stage filtration, activated carbon adsorption, and reverse osmosis technologies.

[0003] In existing direct drinking water purification equipment, filter cartridges are usually used. During the process of wastewater treatment by the filter cartridge, the water flows from top to bottom through the filter cartridge, and the suspended solids in the water flow will be intercepted by the filter cartridge. However, the interception capacity of the filter cartridge is limited. When the water flow is too fast, a single filter cartridge cannot process all the excessive water flow, resulting in poor water purification effect. Summary of the Invention

[0004] The purpose of this invention is to provide a water purification device for direct drinking water systems to solve the above-mentioned problems.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a water purification device for a direct drinking water system, comprising a frame, on which a water purification module is fixedly installed, the water purification module being composed of a water softener, a carbon filter and a sand filter; The carbon filter has a filter compartment, and a filter element is fixedly installed at the top of the filter compartment; A water guide bucket is fixed inside the filter chamber at the bottom of the filter body. The water guide bucket has a funnel-shaped structure with a large opening on the upper side and a small opening on the lower side. The water flow passing through the water guide bucket will be concentrated in the center direction of the filter chamber. The bottom of the water guide bucket is provided with a fixed plate fixed to the inner wall of the filter chamber. A water passage hole is provided in the center of the fixed plate. With the water passage hole as the center, several water outlet grooves and through holes are opened on the fixed plate. A movable plate is provided at the bottom of the fixed plate. The movable plate is in close contact with the fixed plate. Several guide rods are fixed on the movable plate. The guide rods pass through the through holes. A baffle is fixed at the top of the guide rod. A spring is fixed between the baffle and the fixed plate. The spring is in a compressed state. Several water passage grooves are opened on the movable plate at the position opposite to the water passage hole. An installation plate fixed to the inner wall of the filter compartment is provided at the bottom of the movable plate. The core filter element is fixed at the center of the installation plate, and several secondary filter elements are fixedly installed on the installation plate around the core filter element. Preferably, a sealing ring is provided at the contact position between the fixed disk and the movable disk.

[0006] Preferably, a water collection hopper is fixedly installed at the bottom of the mounting plate, the water collection hopper is fixedly connected to a drain pipe, the drain pipe is used for water discharge, and both the core filter element and the secondary filter element are fixedly connected to the mounting plate.

[0007] Preferably, the filter body is divided into a coarse filter screen, a fine filter screen and an activated carbon filter screen from top to bottom, and an inlet is opened at the top of the carbon filter.

[0008] Preferably, a rotating shaft is provided through the movable disk, and the rotating shaft is rotatably connected to the movable disk through a bearing.

[0009] Preferably, a turbine is fixed at the upper end of the rotating shaft, the turbine is directly opposite the bottom opening of the water guide bucket, and the water flowing out from the bottom of the water guide bucket will drive the turbine to rotate, and an agitator is fixed at the lower end of the rotating shaft.

[0010] In summary, the present invention has the following beneficial effects: 1. The water purification equipment of the present invention consists of a water softener, a carbon filter and a sand filter, which comprehensively treats water and has a good treatment effect.

[0011] 2. Fix a water guide bucket inside the filter compartment of the carbon filter. The water guide bucket has a funnel-shaped structure with a large opening on the upper side and a small opening on the lower side. The water flow passing through the water guide bucket will be concentrated in the center of the filter compartment and directly facing the core filter element, thereby optimizing the filtration effect.

[0012] 3. A fixed plate, fixed to the inner wall of the filter chamber, is set at the bottom of the water guide bucket. A water passage hole is set through the fixed plate at its center. A movable plate is slidably set at the bottom of the fixed plate by a spring. An installation plate, fixed to the inner wall of the filter chamber, is set at the bottom of the movable plate. The core filter element is fixed at the center of the installation plate, and several secondary filter elements are fixedly installed on the installation plate around the core filter element. When the water flow rate is low, the water flowing out through the lower opening of the water guide bucket will flow through the water passage hole and out through each water passage groove, directly to the core filter element for further filtration. When the water flow rate is too high, the water flow pushes the movable plate away from the fixed plate to form a gap. The spring is further compressed, and some water will flow along the outlet groove and through the gap between the movable plate and the fixed plate towards the inner wall of the filter chamber, and then flow along the inner wall of the filter chamber to the secondary filter element for filtration. This ensures that there is still a good filtration effect even when the water flow rate is too high. Thus, this application can achieve good purification effect for water flows with different flow rates.

[0013] 4. Fix a turbine at the upper end of the rotating shaft, with the turbine facing the bottom opening of the water guide hopper. The water flowing out from the bottom of the water guide hopper will drive the turbine to rotate. Fix an agitator at the lower end of the rotating shaft. The agitator rotates with the rotating shaft and forms a vortex after the agitator rotates. The water flow at the bottom of the agitator converges towards the agitator, thereby guiding the water flowing out from the gap between the movable plate and the fixed plate toward the secondary filter element, enhancing the filtration effect.

[0017] Example 1: Combined with appendix Figures 1-5 The water purification equipment for a direct drinking water system includes a frame 10, on which a water purification module 11 is fixedly installed. The water purification module 11 consists of a water softener 12, a carbon filter 13, and a sand filter 14. The direction of water flow to be treated is from the sand filter 14 to the carbon filter 13 and then to the water softener 12; The sand filter 14 has a primary filtration function, and its interior is filled with homogeneous quartz sand of equal particle size, forming a sand bed.

[0018] The carbon filter 13 has a comprehensive filtration function, which performs secondary treatment on the water that was initially filtered within the carbon filter 13.

[0019] The water softener 12 is used for water softening. A cation exchange resin is used in the water softener 12 to remove calcium and magnesium ions from the water, thereby reducing the hardness of the water to be treated.

[0020] The carbon filter 13 has a filter chamber 38, and a filter body 37 is fixedly installed at the top of the filter chamber 38. The filter body 37 is divided into a coarse filter screen 16, a fine filter screen 17 and an activated carbon filter screen 18 from top to bottom. A water inlet 15 is opened at the top of the carbon filter 13. The water to be treated enters through the water inlet 15 and is processed by passing through the coarse filter screen 16, the fine filter screen 17 and the activated carbon filter screen 18 in sequence. It should be noted that the coarse filter 16 intercepts large particles, the fine filter 17 intercepts small suspended particles, and the activated carbon filter 18 is used to adsorb odors in the water.

[0021] A water guide bucket 19 is fixed inside the filter chamber 38 at the bottom of the filter body 37. The water guide bucket 19 has a funnel-shaped structure with a large opening on the upper side and a small opening on the lower side. The water flow passing through the water guide bucket 19 will be accelerated and concentrated in the center direction of the filter chamber 38. The bottom of the water guide hopper 19 is provided with a fixing plate 21 that is fixed to the inner wall of the filter chamber 38. (See reference) Figure 5 The fixed disk 21 has a water passage hole 23 through the center of the fixed disk 21. With the water passage hole 23 as the center, a plurality of water outlet grooves 22 and through holes 35 through the fixed disk 21 are opened on the fixed disk 21. A movable disk 28 is set at the bottom of the fixed disk 21. The movable disk 28 is in close contact with the fixed disk 21. A plurality of guide rods 24 are fixed on the movable disk 28. The guide rods 24 pass through the through holes 35. A baffle 25 is fixed at the top of the guide rods 24. A spring 20 is fixed between the baffle 25 and the fixed disk 21. A plurality of water passage grooves 27 are opened on the movable disk 28 directly opposite the water passage hole 23. A mounting plate 39 is provided at the bottom of the movable plate 28 and fixed to the inner wall of the filter compartment 38. A core filter element 31 is fixed at the center of the mounting plate 39, and a number of secondary filter elements 32 are arranged around the core filter element 31 and fixedly installed on the mounting plate 39. The water passage 23 is positioned directly opposite the lower opening of the water guide bucket 19. When the water flow rate is low, the water flowing out through the lower opening of the water guide bucket 19 will pass through the water passage 23 and flow out from each of the water passage grooves 27, directly to the core filter element 31, where it will be further filtered. It should be noted that when the water flow rate is low, the spring 20 is in a compressed state, which allows the fixed plate 21 and the movable plate 28 to fit better, and the water flowing through the water hole 23 will not flow out from between the fixed plate 21 and the movable plate 28. In particular, a sealing ring can be added at the contact position between the fixed plate 21 and the movable plate 28 to optimize the sealing effect.

[0022] When the water flow velocity is too high (meaning the water to be processed per unit time exceeds the processing capacity of the core filter element 31), the water flow pushes the movable disc 28 away from the fixed disc 21 to form a gap. The spring 20 is further compressed, and some water flows along the outlet groove 22 and from the gap between the movable disc 28 and the fixed disc 21 towards the inner wall of the filter chamber 38. It then flows along the inner wall of the filter chamber 38 to the position of the secondary filter element 32, where it is filtered. This ensures that there is still a good filtration effect even when the water flow velocity is too high.

[0023] A water collection hopper 33 is fixedly installed at the bottom of the mounting plate 39. The water collection hopper 33 is fixedly connected to a drain pipe 34, which is used for water discharge. The core filter element 31 and the secondary filter element 32 are both fixedly connected to the mounting plate 39. Water filtered by the core filter element 31 and the secondary filter element 32 will flow into the water collection hopper 33 and be discharged from the drain pipe 34.

[0024] Example 2: The difference from Embodiment 1 is that a rotating shaft 29 is provided through the movable disk 28, and the rotating shaft 29 is rotatably connected to the movable disk 28 through a bearing; A turbine 26 is fixed at the upper end of the rotating shaft 29. The turbine 26 is directly opposite the bottom opening of the water guide bucket 19. The water flowing out from the bottom of the water guide bucket 19 will drive the turbine 26 to rotate, thereby driving the rotating shaft 29 to rotate. An agitator 30 is fixed at the lower end of the rotating shaft 29. The agitator 30 rotates with the rotating shaft 29. After the agitator 30 rotates, a vortex is formed. The water flow direction at the bottom of the agitator 30 is towards the agitator 30, thereby guiding the water flowing out from the gap between the movable plate 28 and the fixed plate 21 toward the secondary filter element 32, thus enhancing the filtration effect.

[0025] How to use: The water to be treated flows into the filter chamber 38 from the inlet 15, and is processed by the coarse filter 16, the fine filter 17 and the activated carbon filter 18. The water flows into the guide bucket 19 and converges towards the center of the filter chamber 38. The converged water flows into the water passage 23, while driving the turbine 26 to rotate. When the water flow rate is low, all the water flows out from the water passage 27 to the core filter element 31, is filtered by the core filter element 31, flows into the water collection hopper 33, and is discharged through the drain pipe 34. When the water flow rate is too high, the water will push the movable disc 28 away from the fixed disc 21 to form a gap, the spring 20 will be further compressed, and some water will flow along the water outlet 22 and from the gap between the movable disc 28 and the fixed disc 21 towards the inner wall of the filter chamber 38, and flow along the inner wall of the filter chamber 38 to the position of the secondary filter element 32, where it will be filtered. The turbine 26 drives the rotating shaft 29 to rotate, and the stirring wheel 30 rotates with the rotating shaft 29. After the stirring wheel 30 rotates, a vortex is formed. The water flow direction at the bottom of the stirring wheel 30 is towards the stirring wheel 30, thereby guiding the water flowing out from the gap between the movable disc 28 and the fixed disc 21 toward the secondary filter element 32.

They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
