Description

Technical Field

[0001] The utility model relates to the field of water purification and desalination, in particular to an ion exchange desalination device. Background Art

[0002] Desalination by ion exchange method refers to a desalination method that uses strongly acidic hydrogen-type resin to remove various cations in water, and then uses strongly basic hydroxide-type anion exchange resin to remove various anions in water. An ion exchange desalination device is generally used in the project of water purification and desalination.

[0003] At present, when the ion exchange desalination device feeds water, the water inlet is relatively concentrated, which is not convenient for uniform distribution. Moreover, the activity of water and resin inside the ion exchange desalination device is relatively low, which is not conducive to improving the effect of water purification and desalination.

[0004] Therefore, aiming at the problems that the water inlet of the above device is relatively concentrated, and the activity of water and resin inside the ion exchange desalination device is relatively low, an ion exchange desalination device that can uniformly distribute water addition and can realize the movement of water and resin inside the device can be designed. Summary of the Utility Model

[0005] In order to overcome the problems that when the ion exchange desalination device feeds water, the water inlet is relatively concentrated, which is not convenient for uniform distribution, and the activity of water and resin inside the ion exchange desalination device is relatively low, which is not conducive to improving the effect of water purification and desalination.

[0006] The technical solution of the utility model is: an ion exchange desalination device, including a device tank body, a water inlet pipe is fixedly connected to the upper end of the device tank body, a sealing connecting plate is fixedly installed on the upper side inside the device tank body, a water spray head is fixedly connected to the lower end of the sealing connecting plate, a water outlet pipe is fixedly connected to the lower end of the device tank body, a filter cover is fixedly installed at the lower end inside the sealing connecting plate, filter holes are formed in the filter cover, a protective partition net is fixedly installed at the upper end of the sealing connecting plate, a check valve is fixedly installed on the water inlet pipe, and a check plate is arranged inside the check valve.

[0007] Preferably, a resin inlet is fixedly installed on the upper side of the surface of the device tank body, and a resin outlet is fixedly installed on the lower side of the surface of the device tank body.

[0008] As a preference, sealing covers are detachably connected to the resin inlet and the resin outlet. Ion exchange resin particles are arranged inside the device tank body below the sealing connecting plate. After the device is used for a period of time, it is convenient to replace the internal ion exchange resin particles through the resin inlet and the resin outlet, and at the same time, the sealing cover is used to maintain the sealing performance of the device tank body.

[0009] Preferably, the water spray heads are distributed in a circular array and have an inclined structural design. The water spray heads are located away from the center of the sealing connecting plate and close to the side of the equipment tank, so that the water flow is guided along the inner wall of the equipment tank after the water is discharged, and the force and direction of the water discharge are used to stir the water itself and the ion exchange resin particles.

[0010] Preferably, a control valve is fixedly installed on the surface of the water outlet pipe, and a support foot is fixedly installed on the lower end of the equipment tank body at the side of the water outlet pipe.

[0011] Preferably, the filter cover is designed to be an arc-shaped structure with filter holes evenly distributed, so that the ion exchange resin particles are isolated by the filter cover, so that the water outlet pipe can smoothly discharge water.

[0012] Preferably, the upper end of the check plate is rotatably connected to the check valve, and a weighted ball is fixedly mounted on the lower side of the right end of the check plate.

[0013] Beneficial effects of the utility model:

[0014] 1. The ion exchange desalination device sprays water evenly onto the ion exchange resin particles through a water spray head. When the water level inside the equipment tank reaches a certain level, the water spray head is designed with an inclined structure, so that the force and direction of the water outlet can be used to stir the ion exchange resin particles and the ion exchange resin particles, so that the ion exchange resin particles and water can be more fully contacted, which is conducive to improving the effect of water purification and desalination;

[0015] 2. The ion exchange desalination device uses a protective screen to prevent ion exchange resin particles from entering the upper side of the sealing connection plate, making it difficult to remove the ion exchange resin particles. The check plate and the counterweight ball are used to allow the water pressure to open the check plate when the water inlet pipe is conveying water, so that the water conveyance is completed normally. When the water conveyance stops and the water pressure is lost, the counterweight ball and the check plate will reclose the check valve due to the weight, thereby achieving the check function, which is beneficial to improving the practicality of the ion exchange desalination device.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Please refer to ( Figures 1 - 4 ), the utility model provides an embodiment: an ion exchange desalination device, including an equipment tank body 1, the upper end of the equipment tank body 1 is fixedly connected with a water inlet pipe 2, a sealing connecting plate 3 is fixedly installed on the upper side of the interior of the equipment tank body 1, a water spray head 4 is fixedly connected to the lower end of the sealing connecting plate 3, a water outlet pipe 5 is fixedly connected to the lower end of the equipment tank body 1, a filter cover 6 is fixedly installed at the lower end of the interior of the sealing connecting plate 3, a filter hole 7 is opened on the filter cover 6, a protective partition 8 is fixedly installed on the upper end of the sealing connecting plate 3, a check valve 9 is fixedly installed on the water inlet pipe 2, and a check plate 10 is arranged inside the check valve 9.

[0023] Please refer to ( Figures 1 - 3 ), in this embodiment, a grease inlet 11 is fixedly installed on the upper side of the surface of the equipment tank body 1, and a grease outlet 12 is fixedly installed on the lower side of the surface of the equipment tank body 1, and a sealing cover 13 is detachably connected to the grease inlet 11 and the grease outlet 12. Ion exchange resin particles are arranged on the lower side of the sealing connecting plate 3 inside the equipment tank body 1, and the water spray heads 4 are distributed in a circular array. The water spray heads 4 are designed with an inclined structure. Water is evenly sprayed onto the ion exchange resin particles through the water spray heads 4. When the water level inside the equipment tank body 1 reaches a certain level, the water spray heads 4 are designed with an inclined structure, so that the force and direction of the water outlet are used to complete the stirring of the ion exchange resin particles and the ion exchange resin particles, so that the ion exchange resin particles and water can be more fully in contact, which is beneficial to improving the effect of water purification and desalination.

[0024] Please refer to ( Figure 1 , Figure 2 and Figure 4), in this embodiment, a control valve 14 is fixedly installed on the surface of the water outlet pipe 5, a support foot 15 is fixedly installed on the lower end of the equipment tank body 1 at the side of the water outlet pipe 5, the filter cover 6 is designed in an arc-shaped structure, and the filter holes 7 are evenly distributed. The upper end of the check plate 10 is rotatably connected to the check valve 9, and a counterweight ball 16 is fixedly installed on the lower side of the right end of the check plate 10. The protective partition 8 is used to prevent ion exchange resin particles from entering the upper side of the sealing connecting plate 3, which makes it difficult to remove the ion exchange resin particles. The check plate 10 and the counterweight ball 16 are used to allow the water pressure to prop open the check plate 10 when the water inlet pipe 2 is conveying water, and the water conveyance is completed normally. When the water conveyance stops and the water pressure is lost, the counterweight ball 16 and the check plate 10 will reclose the check valve 9 due to the weight force, thereby achieving the check function, which is beneficial to improving the practicality of the ion exchange desalination device.

[0025] When working, water is delivered and loaded from the water inlet pipe 2, and water is evenly sprayed onto the ion exchange resin particles through the water spray head 4. When the water level inside the equipment tank 1 reaches a certain level, the water spray head 4 is designed with an inclined structure, so that the force and direction of the water outlet can be used to complete the stirring of itself and the ion exchange resin particles, so that the ion exchange resin particles and water can be more fully in contact. The protective partition 8 is used to prevent the ion exchange resin particles from entering the upper side of the sealing connecting plate 3, making it difficult to remove the ion exchange resin particles. The check plate 10 and the counterweight ball 16 are used to allow the water inlet pipe 2 to deliver water, and the check plate 10 can be opened by water pressure to complete the water delivery normally. When the water delivery stops and the water pressure is lost, the counterweight ball 16 and the check plate 10 will reclose the check valve 9 due to the weight to achieve the check function.

[0026] Through the above steps, the force and direction of the outlet water are used to stir the water and the ion exchange resin particles, so that the ion exchange resin particles and water can be in more complete contact, so as to solve the problem that the incoming water is relatively concentrated, inconvenient and not evenly distributed, and the activity of water and resin inside the ion exchange desalination device is relatively low.
