Description

Technical Field

[0001] The utility model relates to the technical field of water treatment equipment, in particular to a multi-stage pure water treatment equipment. Background Art

[0002] Pure water multi-stage treatment equipment is an advanced water treatment device that uses multi-stage filtration technology to effectively remove harmful substances and impurities from water, providing high-purity drinking water and industrial water. Its core component is the reverse osmosis membrane, which can effectively intercept harmful substances such as microorganisms, heavy metals, and organic matter in the water, as well as remove particles, odor, and color. With the synergistic effect of the multi-stage filtration system, pure water equipment can achieve efficient water purification and produce sterile, transparent, and refreshing drinking water. In addition, the filtration accuracy of industrial pure water equipment is also an important indicator for evaluating its quality. The design and material selection of the filter element have a great influence on the filtration accuracy. Common filter element materials include ceramics, cellulose, precision filter membranes, etc. Different filter element materials correspond to different filtration accuracies.

[0003] In the current existing technology, after filter cartridges with different filter media are connected in series with the hydrophobic pipe, the usage load of the filter media therein is related to the content of each component in the water passing through. This makes the replacement cycle of filter cartridges containing different filter media vary to a certain extent. Existing devices usually replace all filter cartridges as a whole after the device is stopped. This method may not fully utilize the use value of the filter cartridges.

[0004] Therefore, a pure water multi-stage treatment device is proposed to solve the above problems. Utility Model Content

The existing devices usually replace each filter cartridge as a whole after the device is stopped. This method may not fully utilize the use value of the filter cartridge.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a pure water multi-stage treatment equipment described in the present invention includes a mounting frame, and the vertical rods on both sides of the mounting frame are symmetrically provided with multiple first through holes, and the multiple first through holes are equidistantly opened along the side direction of the vertical plate of the mounting frame. Multiple pipe components are symmetrically installed at both ends of the mounting frame, and the pipe components include a main pipe, which is clamped between the inner walls of the first through holes, one end of the main pipe is connected to a first connecting flange, and the outer wall of the main pipe is vertically connected to an L-shaped elbow, and one end of the L-shaped elbow is connected to a second connecting flange, a filter cylinder is installed between two adjacent first connecting flanges, and multiple auxiliary components are arranged outside the filter cylinders.

[0013] Preferably, a motor is installed on the top of the mounting bracket, and the output shaft of the motor is connected to the axis of the lifting screw.

[0014] Beneficial effects of the utility model:

[0015] In the present invention, the pipe assemblies on both sides of the mounting frame cooperate with each other to connect with the filter cylinder. After the filter cylinder has been used for a period of time, when the filter medium load in one of the filter cylinders is large and needs to be replaced, the spare filter cylinder is connected between the second connecting flange of the pipe assembly connected to it, and then the second electrically controlled valve is opened and the first electrically controlled valve is closed.

[0025] Specific examples are given below.

[0026] See also Figure 1 - Figure 5The utility model provides a pure water multi-stage treatment equipment, including a mounting frame 1, a plurality of first through holes 11 are symmetrically opened on the vertical bars on both sides of the mounting frame 1, and the plurality of first through holes 11 are equidistantly opened along the side direction of the vertical plate of the mounting frame 1, and a plurality of pipe components 2 are symmetrically installed on both ends of the mounting frame 1, and the pipe component 2 includes a main pipe 21, and the main pipe 21 is clamped between the inner walls of the first through hole 11, and one end of the main pipe 21 is connected to a first connecting flange 211, and the outer wall of the main pipe 21 is vertically connected to an L-shaped elbow 22, and one end of the L-shaped elbow 22 is connected to a second connecting flange 221, and a filter cylinder 3 is installed between two adjacent first connecting flanges 211, and auxiliary components 4 are arranged outside the plurality of filter cylinders 3, and a first electric-controlled valve 212 is installed on the outer wall of the main pipe 21, and the first electric-controlled valve 212 is close to the end where the first connecting flange 211 is located, and a second electric-controlled valve 222 is installed on the outer wall of the L-shaped elbow 22, and the second electric-controlled valve 222 is close to the second connecting flange 22 1, the pipe assembly 2 is installed on both sides of the mounting frame 1 through the first through hole 11, and the connecting flanges at both ends of the filter cylinder 3 and the first connecting flanges 211 at one end of the two adjacent main pipes 21 are matched with each other to realize the docking and fixation between the main pipe 21 and the filter cylinder 3. When the filter cylinder 3 has been used for a period of time and the filter medium load in one of the filter cylinders 3 is large and needs to be replaced, the spare filter cylinder 3 is connected between the second connecting flange 221 at one end of the L-shaped elbow 22 of the pipe assembly 2 connected thereto, and then the second electric control valve 222 is opened and the first electric control valve 212 is closed. At this time, water can pass through the spare filter cylinder 3, ensuring the filtering effect of the device on water. In addition, each filter cylinder 3 can be fully utilized, increasing the practicality of the device. The auxiliary component 4 can support and lift the spare filter cylinder 3, facilitating the installation and docking process between the spare filter cylinder 3 and the second connecting flange 221;

[0027] like Figure 1 、 Figure 3 and Figure 5As shown, the auxiliary component 4 includes a supporting plate 41, and the supporting plate 41 is fixedly connected to a linkage plate 42 on the side where the filter cylinder 3 is located. A second through hole 43 is opened on the top surface of each end of the linkage plate 42, and a guide rod 44 is slidably passed through the inner walls of the two second through holes 43. Both ends of the guide rod 44 are vertically fixed to the inner wall of the mounting frame 1, and a threaded sleeve 45 is installed at the center of the top surface of the linkage plate 42. A lifting screw rod 46 is installed on the inner thread of the threaded sleeve 45. The two ends of the lifting screw rod 46 are vertically fixed to the inner wall of the mounting frame 1 through bearings. A motor 5 is installed on the top of the mounting frame 1. The output shaft is connected to the axis of the lifting screw 45. The support plate 41 is limited by the cooperation of the second through hole 43 on the linkage plate 42 and the guide rod 44 between the mounting frame 1.

The support plate 41 is limited by the cooperation of the second through hole 43 on the linkage plate 42 and the guide rod 44 between the mounting frame 1. When the spare filter cylinder 3 is placed in the top surface groove of the support plate 41, it can rise and fall with the overall rise and fall of the support plate 41 to ensure that the auxiliary component 4 provides auxiliary support to the spare filter cylinder 3 when the filter cylinders 3 of different heights are replaced. The linkage plate 42 is linked with the lifting screw 46 through the threaded sleeve 45. The rotation of the lifting screw 46 under the output force of the motor 5 can control the lifting of the support plate 41.
