[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] The utility model provides a deionized water preparation device, comprising a filter cartridge 1, a water inlet pipe 2 and a water outlet pipe 3, the filter cartridge 1 is filled with ion exchange resin for filtering deionized water, and a gas exhaust valve 4 is arranged on the top of the filter cartridge 1; one end of the water inlet pipe 2 extends into the filter cartridge 1 and is arranged close to the bottom wall of the filter cartridge 1, and the other end of the water inlet pipe 2 is communicated with water to be filtered; one end of the water inlet pipe 2 extending into the filter cartridge 1 is connected with a drainage pipe 5, an axis of the drainage pipe 5 and the axis of the water inlet pipe 2 have an angle, and the outlet of the drainage pipe 5 is arranged toward the side wall of the filter cartridge 1; one end of the water outlet pipe 3 extends into the filter cartridge 1 and is arranged close to the top wall of the filter cartridge 1, and the other end of the water outlet pipe 3 is communicated with a water-using device; filtering elements are arranged at the water outlet pipe 3 and the gas exhaust valve 4.

[0031] In the deionized water preparation device of the utility model, the water to be filtered from the external water source is passed into the filter cartridge 1 through the water inlet pipe 2. The filter cartridge 1 is filled with ion exchange resin to adsorb ions in the water to be filtered. After adsorption, deionized water is obtained. The deionized water is discharged through the water outlet pipe 3. The deionized water can be used for cooling and cleaning workpieces in the processing process, improving the processing quality of the workpieces and extending the service life of the processing equipment. At the same time, one end of the water inlet pipe 2 of the utility model extending into the filter cartridge 1 is connected to a drainage pipe 5. The axis of the drainage pipe 5 and the axis of the water inlet pipe 2 have an angle to change the water inlet direction and realize the water flow drainage effect, so that the water flow introduced by the water inlet pipe 2 forms a vortex, increases the contact area between the water to be filtered and the ion exchange resin, enhances the ion adsorption effect, and improves the ion adsorption efficiency. The spirally rising water flow is discharged from the water outlet pipe 3 near the top of the filter cartridge 1. The utility model provides filter elements at the outlet pipe 3 and the exhaust valve 4 to prevent the ion exchange resin from clogging the outlet pipe 3 and the exhaust valve 4, thereby improving the working reliability of the device. The deionized water preparation device of the utility model has a simple and compact structure, is suitable for various electrical processing equipment, and has strong adaptability.

[0032] It should be explained that the specific type of ion exchange resin and the filling rate of the ion exchange resin in the filter cartridge 1 are conventional means used by those skilled in the art and will not be described in detail here.

[0033] Among them, the filter cartridge 1 includes a cartridge body 101 and a cartridge top 102 and a cartridge bottom 103 respectively arranged at both ends of the cartridge body 101. The filter cartridge 1 is a cylindrical structure to avoid affecting the flow of water and to avoid dead corners that cause ion exchange resin accumulation and affect the ion adsorption effect. The water inlet pipe 2 and the water outlet pipe 3 are both extended from the cartridge top 102. The extended ends of the water inlet pipe 2 and the water outlet pipe 3 are both connected with a connecting elbow 8, which is convenient for connection with an external water source and water-using equipment, further improving the adaptability of the device. The exhaust valve 4 is arranged on the cartridge top 102 to ensure the air pressure balance in the filter cartridge 1 and ensure the normal operation of the device.

[0034] It should also be noted that both the top 102 and the bottom 103 of the cartridge are downwardly concave arc-shaped structures, which are beneficial to further improve the uniformity of water flow in the filter cartridge 1, optimize water flow dynamics, reduce water flow stagnation areas, and reduce deposition, thereby preventing the ion exchange resin from clogging the exhaust valve 4.

[0035] In actual applications, in order to facilitate disassembly and assembly, a connector 6 is provided on the top 102 of the cylinder. Both the water inlet pipe 2 and the water outlet pipe 3 can be set to a split structure, and both are connected to the filter cylinder 1 by means of the connector 6, that is, the water inlet pipe 2 and the water outlet pipe 3 are set to at least a two-section structure, and the upper and lower sections of the water outlet pipe 3 are respectively sealed and connected to the connector 6 to form the water outlet pipe 3, which is convenient for disassembly and assembly and maintenance. Two connectors 6 are provided, and the water inlet pipe 2 also adopts this installation method. In addition, the lower section of the water inlet pipe 2 can adopt a multi-section structure, which is convenient for adjusting the depth of the water inlet pipe 2 extending into the filter cylinder 1 to adapt to various adsorption and filtration conditions and enhance the flexibility and adaptability of the device.

[0036] Specifically, the bottom 103 and the body 101 are detachably connected and a sealing element is provided between the two, which is convenient for disassembly and assembly, and convenient for replacement, cleaning and maintenance of the filled ion exchange resin. The bottom 103 and the body 101 can be connected by threads, which is convenient for disassembly and assembly, and can also be connected by clamps and other connection methods, which is convenient for operation. A sealing element is provided between the bottom 103 and the body 101 to ensure the sealing of the filter cartridge 1. The bottom 103 is also connected to the base 104, which improves the structural stability of the filter cartridge 1 and further improves the working reliability of the device.

[0037] For the convenience of operation, two handles 7 are connected to the top 102 of the cylinder, which are convenient for operators to carry and transfer the filter cylinder 1. The two handles 7 are symmetrically arranged with the axis of the cylinder body 101 as the symmetry axis. The handles 7 are inverted U-shaped, which is convenient for applying force. The height of the handles 7 is higher than the height of the parts of the water inlet pipe 2 and the water outlet pipe 3 extending from the cylinder body 101. When the cylinder bottom 103 and the cylinder body 101 are disassembled, the filter cylinder 1 can be turned over 180° to make it in an inverted state. At this time, the handles 7 can act as a support foot, which further facilitates operation and protects the exposed parts of the water inlet pipe 2, the water outlet pipe 3 and components such as the exhaust valve 4, thereby improving the convenience of operation and extending the service life of the device.

[0038] In this specific embodiment, the axis of the drainage pipe 5 is perpendicular to the axis of the water inlet pipe 2, and the drainage pipe 5 is connected to the water inlet pipe 2 by means of a connecting elbow 8. In practical applications, the setting angle of the drainage pipe 5 can also be adjusted according to the specifications of the filter cartridge 1 and the drainage pipe 5, and the angle of the elbow formed by the drainage pipe 5 and the water inlet pipe 2 can be reasonably set so that the water flow introduced into the filter cartridge 1 forms a vortex spiral rise, so that the water to be filtered is fully in contact with the ion exchange resin, thereby enhancing the exchange and adsorption effect of the ion exchange resin.

[0039] In this specific embodiment, the diameter of the drainage tube 5 is consistent with the diameter of the water inlet pipe 2. In practical applications, the water inlet amount of the filter cartridge 1 can be changed by adjusting the diameter of the drainage tube 5 to meet different working conditions. The drainage tube 5 is detachably connected to the water inlet pipe 2, which facilitates the disassembly, assembly and replacement of the drainage tube 5.

[0040] It should also be noted that the water inlet pipe 2 and the water outlet pipe 3 are symmetrically arranged with the axis of the filter cartridge 1 as the symmetry axis, ensuring smooth water inlet and outlet, improving the force uniformity of the filter cartridge 1, and thus ensuring the working stability of the device.

[0041] Furthermore, an ion concentration sensor is also provided in the filter cartridge 1 to monitor the ion concentration, so that the operator can monitor the working state of the filter device. In practical applications, a control module can also be provided, and the ion concentration sensor is connected to the control module for communication, so that the operator can timely understand the working state of the device, further improve the convenience of operation of the device, and reduce the labor burden of the operator.

[0042] In the deionized water preparation device of the utility model, the filter cartridge 1 is filled with ion exchange resin, which is used to perform ion exchange and adsorption on the water introduced into the filter cartridge 1 to obtain deionized water, and the deionized water is led out to the electrical processing equipment or other water-using equipment through the outlet pipe 3 to ensure the smooth progress of the electrical processing process. The water inlet pipe 2 of the utility model is connected with the drainage pipe 5, and the water inlet pipe 2 and the drainage pipe 5 are connected and form a curved pipe structure to guide the water flow, and the water flow forms a vortex, which increases the contact area between the water to be filtered and the ion exchange resin, enhances the filtering effect, and improves the preparation efficiency of the device.
