Description

Technical Field

[0001] The utility model relates to the technical field of purified water production, in particular to a purification device which is convenient for maintenance. Background Technique

[0002] The working principle of a pharmaceutical purified water device is a scientific water treatment technology that purifies water quality by the directional movement of dielectric ions in water passing through a diaphragm under the action of a direct current electric field, and utilizes the selective permeability of an ion exchange membrane to ions. Between a pair of electrodes of an electrodialyzer, there are usually multiple groups of anion membranes, cation membranes and diaphragms arranged alternately to form a concentrated chamber and a dilute chamber. Cations in the water in the dilute chamber migrate towards the negative electrode and pass through the cation membrane, being intercepted by the anion membrane in the concentrated chamber. Anions in the water migrate towards the positive electrode through the anion membrane and are intercepted by the cation membrane in the concentrated chamber. In this way, the number of ions in the water passing through the dilute chamber gradually decreases to become fresh water, while in the water in the concentrated chamber, due to the continuous influx of cations and anions in the concentrated chamber, the concentration of dielectric ions continuously increases to become concentrated water, so as to achieve the purpose of desalination, purification, concentration or refining. The pharmaceutical purified water device can meet the needs of the pharmaceutical industry for preparing purified water.

[0003] After most current purification devices are used for a period of time, the filter elements inside the filtering mechanism need to be replaced. However, the filtering mechanism is usually composed of three parts: a sand filter, a carbon filter and a softening filter, which are fixed separately and are relatively troublesome to disassemble. Not only do they need to be removed from the base, but the connecting pipes between the filters also need to be removed, which is rather troublesome. Therefore, the present application provides a purification device that is convenient for maintenance to solve the problems raised in the above background technique. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a purification device that is convenient for maintenance is proposed. When the device is in use, by fixing the three filters together up and down, all the filters can be disassembled at one time during maintenance, which is very convenient. In addition, through the fixing mechanism, the user can also choose to disassemble the filters separately without having to remove all the filters.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a purification device that is convenient for maintenance, including a first base plate, a support mechanism, a fixing mechanism and a filtering mechanism. The support mechanism includes a bracket, upper and lower fixing frames are respectively fixedly arranged at the upper and lower ends of the bracket, a motor is fixedly arranged at the bottom inside the bracket, and a screw rod is fixedly arranged at the output end of the motor. The filtering mechanism includes a sand filter, a carbon filter and a softening filter;

[0006] The fixing mechanism includes a fixing ring and a connecting block. Inside one side of the fixing ring, a second fixing block is fixedly arranged. On both sides of the second fixing block, fixing clips are rotatably arranged. A first spring is connected between the two fixing clips. On the opposite sides of the two fixing clips, connecting plates are rotatably arranged. On the opposite sides of the two connecting plates, they are rotatably arranged inside the connecting block. The part of the fixing ring between the two fixing clips is internally fixedly provided with an electric telescopic rod, and the output end of the electric telescopic rod is fixedly arranged on one side of the connecting block;

[0007] Through the above technical solution, when the device is in use, by fixing the three filters together up and down, it is more rapid and convenient for the user to disassemble. In addition, by pushing the connecting block through the electric telescopic rod, the two connecting plates are driven to move forward, so that the fixing clips are opened. Then the motor drives the screw to rotate, and the screw drives the fixing mechanism to move up and down. When only the first filter needs to be removed, the fixing device can be moved around the second filter, and then the electric telescopic rod is retracted to fix the fixing frame inside the groove. At this time, the second fixing block will limit the filter to prevent it from rotating. When the upper filter is disassembled at this time, it will not affect the lower filter.

[0008] Furthermore, a raw water tank is fixedly arranged at the front of the upper end of the first base plate. An inlet is fixedly arranged at the upper end of the raw water tank. A raw water booster pump is fixedly arranged in the middle of the upper end of the first base plate;

A bolt is threadedly sleeved inside the two fixing blocks. A fixing column is fixedly arranged between the upper fixing frame and the lower fixing frame;

[0011] Through the above technical solution, through the fixing cover, it is beneficial to fix the filtering mechanism after installation to avoid shaking and leave an interface. Through the bolt, it is beneficial to fix the fixing cover and the upper fixing frame together to prevent the fixing cover from opening by itself. Through the fixing column, it is beneficial to support the upper fixing frame to make it more stable.

[0012] Furthermore, the sand filter, the carbon filter and the softening filter are all threadedly sleeved together up and down. The water outlets of the sand filter and the carbon filter are threadedly sleeved inside the next filtering tank;

[0013] Through the above technical solution, it is beneficial to make it more convenient to replace the internal filter element during disassembly, without the need to disassemble one by one, and it is beneficial to prevent the internal water from flowing out.

[0014] Furthermore, third fixing blocks are fixedly arranged on both the front and rear sides of the sand filter and the carbon filter. Grooves are formed on both sides of the four third fixing blocks. Four third fixing blocks are fixedly arranged around the softening filter, and two of the four third fixing blocks are provided with grooves.

[0015] Through the above technical solution, through the third fixing blocks, it is beneficial to limit the filtering mechanism through the second fixing blocks. Through the grooves, it is beneficial to support the fixing mechanism and make it more stable.

[0016] Furthermore, second springs are fixedly arranged inside the upper ends of both sides of the softening filter and the carbon filter. Second bottom plates are fixedly arranged at the upper ends of the four second springs. Connecting rings are fixedly arranged at the upper ends of the four second bottom plates.

[0017] Through the above technical solution, through the second springs, when the filtering mechanism is installed, the connecting rings can be retracted into the upper part of the filter to avoid gaps. When the upper filter is removed, the connecting rings will pop out under the push of the second springs, facilitating the user to take out the filter with mechanical tools.

[0018] Furthermore, the bracket and the lower fixing frame are fixedly arranged at the rear of the upper end of the first bottom plate. The sand filter, the carbon filter, and the softening filter are slidably arranged inside the fixing mechanism and the supporting mechanism.

[0019] Through the above technical solution, through the bracket, it is beneficial to the motor and the screw rod, and it is beneficial to wrap them inside the bracket. Through the sand filter, the carbon filter, and the softening filter, it is beneficial to filter water.

[0020] The utility model has the following beneficial effects:

[0021] 1. A purification device convenient for maintenance proposed by the utility model. When the device is in use, by connecting the three filters together, when it is necessary to replace the filter elements inside, it is convenient to disassemble them. In addition, when the user only needs to remove the uppermost one, the motor drives the screw rod to rotate, driving the fixing mechanism to move up and down around the lower filter. At this time, the upper filter can be removed without affecting the lower filter.

[0038] Working principle: When the filter mechanism 7 needs to be removed to replace the internal filter element, the bolt 507 can be disassembled, and then the fixing cover 502 can be opened. Then, the electric telescopic rod 607 is used to push the connecting block 604. The connecting block 604 drives the fixing frame to open through two connecting plates 603, so that the convex block of the fixing frame disengages from the third fixing block 704. At this time, the filter mechanism 7 can be taken out completely, facilitating the replacement of its internal filter element. When only the uppermost one needs to be replaced, the motor 505 drives the screw rod 504 to rotate. The screw rod 504 drives the fixing mechanism 6 to move up and down until it stays around the second carbon filter 702. At this time, the output end of the electric telescopic rod 607 is retracted, so that the fixing frame is fixed on both sides of the third fixing block 704 around the carbon filter 702, and the second fixing block 601 will limit the carbon filter 702, and it will not be affected when the user disassembles the sand filter 701.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
