Description

Technical Field

[0001] The utility model relates to the technical field of mixed bed water inlet devices, in particular to a water inlet device for a mixed ion exchanger. Background Art

[0002] Mixed ion exchanger, also known as mixed bed, is a desalted water purification equipment commonly used in the water treatment field. It uses ion exchange resin to exchange and remove ions in water to improve the purity of water. This process is usually used to remove ionic minerals and other impurities in water to meet some applications with high requirements for high-purity water quality, such as boiler water. The water obtained after mixed ion exchange treatment can effectively prevent scale, corrosion, and improve thermal efficiency.

[0003] The common inlet filter of the mixed ion exchanger is a cylinder with a diameter of 47cm × height of 15cm × 60 mesh. Due to its short length (15cm in height), it is affected by the water supply pressure (inlet pressure 0.3Mpa) and flow rate (240m3 / H) of the intermediate water pump. After being distributed through the water inlet baffle of the pipe, the water directly impacts the filter, which can easily cause the filter to be damaged by excessive pressure.

[0004] When the mixed bed is operating and producing water, the water inlet to the filter is from the top and out from the bottom. When the inlet filter is normal, water can be evenly distributed on the resin layer through the filter, allowing the protective layer formed by the resin to effectively intercept anions and cations in the water flow to ensure the quality of the effluent. However, if the inlet filter is damaged, the water flow will directly impact the resin layer at the damaged part, causing the inlet water to flow sideways and destroying the protective layer formed by the resin, resulting in the inability to intercept residual anions and cations, causing abnormal effluent quality.

[0005] During mixed bed regeneration, the filter will change the water inlet mode, and the water inlet and outlet direction will change from top-in and bottom-out during water production to bottom-in and top-out. Its function will change from evenly distributing the water inlet to intercepting the anionic and cation resins in the bed. This is because resin will float up in the bed during regeneration and backwashing, so the filter is needed to prevent the resin from leaking out. However, if the water inlet filter is damaged, it will not be able to intercept the floating resin, so it is easy to cause resin leakage. In addition, when the resin floats up, some resin will block the filter, causing the water inlet and backwash drainage to be pressurized, and the effect of separating the water and resin and stratifying the backwash may not be achieved. Utility Model Content

[0006] In view of the above-mentioned prior art, the present invention provides a water inlet device for a mixed ion exchanger, and the main technical problem to be solved is how to improve the stability of the mixed bed water production and regeneration process.

[0007] To achieve the above-mentioned purpose, the technical solution of the embodiment of the utility model is implemented as follows:

[0008] A water inlet device for a mixed ion exchanger comprises a base plate, a support frame and a mesh cylinder. The support frame is arranged on the base plate and comprises a plurality of skeletons and brackets. The skeletons and brackets are arranged in an alternating manner and are used to support the mesh cylinder. A vibration assembly and a drive assembly are provided on the base plate. The vibration assembly comprises a plurality of shrapnel and a lever. The drive assembly drives the lever to hit the shrapnel to cause the base plate to vibrate, and the mesh cylinder cleans the mesh holes through the vibration of the base plate.

[0009] Furthermore, several frames are fixedly connected to the outer side of the top of the bottom plate at equal distances. The frames are in the shape of long strips and are arranged along the radial direction of the bottom plate. The tops of the several frames are fixedly connected to the same connecting ring.

[0010] Furthermore, the bracket is annular, and several brackets are fixedly connected to the frame at equal distances in a state parallel to the bottom plate, the net tube is fixedly connected to the outside of the frame and the bracket, and the top and bottom ends of the net tube are fixedly connected to the connecting ring and the bottom plate respectively.

[0011] Furthermore, the driving assembly includes an impeller, a rotating shaft is rotatably connected to the middle of the top end of the base plate, the impeller is fixedly connected to the top end of the rotating shaft, and the shift rod is equidistantly fixedly connected to the outer side of the bottom end of the impeller.

[0012] Furthermore, the lever is made of rubber and is L-shaped. A number of spring pieces are fixedly connected to the outer side of the top of the bottom plate at equal distances. The positions of the spring pieces and the lever correspond to each other up and down, and the spring pieces are made of spring sheets.

[0013] Furthermore, the top of the base plate is fixedly connected to a plurality of support rods at equal intervals on the outside of the rotating shaft, and the top of the support rods is fixedly connected to a connecting sleeve, which is spherical and has a ball inside.

[0014] Furthermore, a circular opening is provided at the top of the connecting sleeve, and the top of the ball extends to the outside of the connecting sleeve at the circular opening, and the top of the ball is tangent to the bottom wall of the impeller.

[0015] The beneficial effects of the present invention are:

[0016] 1. This device sets the water inlet device of the mixed bed as a cylinder, and at the same time, the bottom is closed with a bottom plate, and a mesh drum supported by a bracket and a frame is arranged on the outside. This not only maintains the strength of the mesh drum, but also changes the water inlet and outlet mode of the mixed bed. That is, during water production, the original water inlet and outlet mode is changed to water outlet around the mesh drum to improve the water inlet deviation phenomenon caused by filter damage. During regeneration and backwashing, the original water inlet and outlet mode is changed to water inlet around the mesh drum to solve the problem of water inlet and regeneration backwashing pressure buildup caused by resin floating up and blocking the mesh holes. In addition, the water flow acting on the impeller can rotate the lever to knock the shrapnel, thereby causing the bottom plate and the mesh drum to vibrate, thereby further preventing mesh blockage and ensuring the stable water production and regeneration process of the mixed bed.

[0017] 2. By extending the length of the mixed bed water inlet device, the surface area of ​​the mesh drum can be expanded. Therefore, even if the resin floats up and enters the mesh of the mesh drum during regeneration and backwashing, the degree of obstruction to the water flow caused by the clogging of the mesh can be effectively reduced, thereby further ensuring the stability of the mixed bed water production and regeneration process;

[0018] 3. When the impeller rotates to drive the lever to strike the shrapnel, the ball bearing can support it at the bottom of the impeller, so that it can rotate more steadily and smoothly, thereby ensuring the stable occurrence of the above-mentioned vibration. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Example 1

[0027] Refer to the attached Figure 1-2 The present application provides a water inlet device for a mixed ion exchanger. The specification of the device is a cylinder with a diameter of 47 cm × a height of 90 cm × a mesh of 60, including a bottom plate 1, a support frame and a net tube 6. The support frame is arranged on the bottom plate 1, and the support frame includes a plurality of skeletons 3 and brackets 4. The number of the brackets 4 is 8 and they are arranged at equal intervals of 10 cm. The skeletons 3 and the brackets 4 are staggered, and the skeletons 3 and the brackets 4 are used to support the net tube 6. The skeletons 3 and the brackets 4 can be staggered to form a cage-like structure, thereby providing sufficient support for the net tube 6 to prevent it from being affected by the water inflow. The vibration component and the driving component are provided on the bottom plate 1. The vibration component includes a plurality of shrapnel 8 and a lever 9. The driving component drives the lever 9 to hit the shrapnel 8 to cause the bottom plate 1 to vibrate. The mesh cylinder 6 cleans the mesh through the vibration of the bottom plate 1. The shrapnel 8 is hit by the lever 9 to make the latter shake, and then the shrapnel 8 is used to cause the bottom plate 1 and the mesh cylinder 6 to vibrate. Therefore, the resin on the mesh cylinder 6 can be cleaned off, avoiding the problem of water inflow and regeneration backwashing pressure caused by clogging of the mesh cylinder 6. The degree of automation is high, and high-frequency manual cleaning operations are no longer required.

[0028] Preferably, several skeletons 3 are fixedly connected to the outer side of the top of the base plate 1 at equal distances. The skeleton 3 is in the shape of an elongated strip and is arranged along the radial direction of the base plate 1. The tops of several skeletons 3 are fixedly connected with the same connecting ring 7. The skeleton 3 and the bracket 4 are both in the form of thin sheets. Both are arranged in a state perpendicular to the mesh tube 6 to avoid the presence of the two affecting the water flow rate, thereby ensuring the smooth flow of water during water production and regeneration.

[0029] Preferably, the bracket 4 is in a circular shape, and several brackets 4 are fixedly connected to the skeleton 3 at equal distances in a state parallel to the base plate 1. The mesh tube 6 is fixedly connected to the outside of the skeleton 3 and the bracket 4, and the top and bottom ends of the mesh tube 6 are fixedly connected to the connecting ring 7 and the base plate 1 respectively. The mesh tube 6 is welded to the base plate 1, the skeleton 3, the bracket 4 and the connecting ring 7, and the mesh tube 6 and the base plate 1 are tightly connected without a gap. Therefore, the bottom of the device can be blocked so that water will not directly impact the resin layer when passing through the mesh tube 6, thereby reducing the impact of the water inlet pressure and flow rate on the resin layer through the filter screen.

[0030] Preferably, the driving assembly includes an impeller 5, a rotating shaft 2 is rotatably connected to the middle of the top of the base plate 1, the impeller 5 is fixedly connected to the top of the rotating shaft 2, the impeller 5 and the rotating shaft 2 are connected by a key, and the lever 9 is equidistantly fixedly connected to the outer side of the bottom end of the impeller 5. When the water flow acts on the impeller 5, it can be rotated, so the impeller 5 can drive the lever 9 to rotate, and then continuously hit the shrapnel 8 to cause it to vibrate. Since the shrapnel 8 is fixed to the base plate 1, the shaking of the shrapnel 8 can cause the base plate 1 to vibrate, and then the mesh tube 6 can vibrate, so as to clean the mesh in real time to avoid being blocked by resin.

[0031] Preferably, the material of the lever 9 is rubber, and the lever 9 is "L"-shaped. Several spring pieces 8 are fixedly connected to the outer side of the top of the bottom plate 1 at equal distances. The positions of the spring pieces 8 and the lever 9 correspond to each other up and down. The spring pieces 8 are made of spring sheets. The lever 9 made of rubber will be deformed after hitting the spring pieces 8, so the collision between the two will not hinder the continued rotation of the impeller 5. After being hit, the spring pieces 8 will be deformed and will continue to shake due to their own elastic force, thereby causing the vibration bottom plate 1 and the mesh tube 6 to vibrate.

[0032] Working principle: This device can be installed and used instead of the water inlet filter of the mixed ion exchanger. When the mixed ion exchanger produces water, water enters the mesh tube 6 from the top and exits from the periphery. When the mixed ion exchanger is regenerated, water enters the mesh tube 6 from the periphery and exits from the top. During this process, the skeleton 3 and the bracket 4 can form a cage-like support structure, thereby maintaining the strength of the mesh tube 6 and preventing it from being deformed or damaged by the inflow of water. At the same time, since the bottom plate 1 can seal the bottom of the device, the impact of the inflow pressure and flow rate through the mesh tube 6 on the resin layer can be reduced.

[0033] In addition, the water flow in the mesh tube 6 will act on the impeller 5 and make it rotate, so the impeller 5 can drive the lever 9 to rotate and continuously hit the shrapnel 8, thereby causing the shrapnel 8 to shake, thereby causing the bottom plate 1 and the mesh tube 6 to vibrate, so that the mesh of the mesh tube 6 can be cleaned in real time to prevent it from being blocked by resin.

[0034] Example 2

[0035] Refer to the attached Figure 3 The present application provides a water inlet device for a hybrid ion exchanger. Compared with Example 1, in order to ensure the smooth and stable rotation of the impeller 5, the top of the base plate 1 is fixedly connected to a plurality of support rods 10 at equal intervals on the outside of the rotating shaft 2. The top of the support rod 10 is fixedly connected to a connecting sleeve 11. The connecting sleeve 11 is spherical, and a ball 12 is provided inside the connecting sleeve 11. The ball 12 can support the impeller 5 without affecting its rotation, thereby ensuring the smooth and stable rotation of the impeller 5.

[0036] Preferably, a circular opening is provided at the top of the connecting sleeve 11 , and the top of the ball 12 extends to the outside of the connecting sleeve 11 at the circular opening, and the top of the ball 12 is tangent to the bottom wall of the impeller 5 .

[0037] Working principle: During the rotation of the impeller 5, the ball 12 can provide support for the impeller 5 at the bottom, so as to make its rotation more stable and smooth, thereby ensuring the stable occurrence of the process in which the lever 9 hits the shrapnel 8 to induce vibration.

[0038] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model. The scope of protection of the present utility model should be based on the scope of protection of the claims.
