[0025] When the above structure is in use, the finished hydrogen peroxide first enters the Y-type filter 1 through the pipeline, and the larger solid impurities in the liquid are removed by the Y-type filter 1, and then pumped to the primary filter 3 and the secondary filter 4 by the centrifugal pump 2, and the filtration efficiency and filtration accuracy of the hydrogen peroxide are further improved by the primary filter 3 and the secondary filter 4.

[0026] The primary filter 3 and the secondary filter 4 each include a base 101, a filter barrel 102 is fixedly mounted on the top of the base 101, a top cover 103 is detachably mounted on the top of the filter barrel 102, a liquid outlet pipe 104 and a liquid inlet pipe 105 are fixedly embedded in the bottom of the base 101, a four-way pipe 106 is fixedly mounted on the top of the liquid inlet pipe 105 corresponding to the position of the base 101, a mounting cylinder 107 is fixedly mounted on the surface of the four-way pipe 106, and a filter element 109 is rotatably connected to the inner wall of the mounting cylinder 107, and a liquid inlet cover 110 is fixedly mounted on the top of the filter element 109. A sealing ring is fixedly installed on the inner wall of the liquid inlet cover 110, and the sealing ring is tightly fitted on the surface of the four-way pipe 106. An inner partition mesh tube 108 is fixedly installed on the inner wall of the installation cylinder 107, and the inner partition mesh tube 108 is located on the inner wall of the filter element 109. The installation cylinder 107 and the inner partition mesh tube 108 are tightly fitted on the bottom of the liquid inlet cover 110, and the installation cylinder 107 and the inner partition mesh tube 108 are porous structures. A plurality of holes are provided in the middle of the liquid inlet cover 110, and a plurality of liquid outlet holes 111 are opened on the side wall of the four-way pipe 106, and the liquid outlet holes 111 are located above the liquid inlet cover 110;

[0027] When the above structure is in use, hydrogen peroxide enters the four-way pipe 106 through the liquid inlet pipe 105, and flows from the liquid outlet hole 111 at the top of the four-way pipe 106 to the liquid inlet cover 110, and enters the position between the installation cylinder 107 and the inner partition mesh tube 108 through the hole in the middle of the liquid inlet cover 110, and then the hydrogen peroxide passes through the filter element 109, and has a filtering effect on the hydrogen peroxide. After the hydrogen peroxide passes through the filter element 109, it will pass through the installation cylinder 107 and the inner partition mesh tube 108 and finally fall to the bottom of the filter barrel 102, and be discharged outward from the liquid outlet pipe 104. The hydrogen peroxide is filtered by the filter element 109 in the primary filter 3 and the secondary filter 4, so that impurities in the hydrogen peroxide can be effectively removed.

[0028] A threaded rod 113 is threadedly connected to the top of the inner wall of the four-way tube 106, and a piston 112 is fixedly installed at the bottom of the threaded rod 113, and the piston 112 is tightly fitted to the inner wall of the four-way tube 106. A threaded cover 114 is movably sleeved on the top of the surface of the four-way tube 106, and the threaded cover 114 is fixedly installed on the top of the liquid inlet cover 110. A sealing ring is provided on the inner wall of the threaded cover 114 to form a seal at the connection position between the threaded cover 114 and the four-way tube 106. A threaded ring 115 is threadedly connected to the surface of the threaded cover 114, and the threaded ring 115 is fixedly embedded in the middle of the top cover 103. Two handles 116 are fixedly installed on the top of the threaded cover 114. There are three mounting cylinders 107, and the three mounting cylinders 107 are arranged in a ring shape in the middle of the filter barrel 102. The filtering accuracy of the filter element 109 in the secondary filter 4 is greater than the filtering accuracy of the filter element 109 in the primary filter 3.

[0029] When the above structure is in use, the threaded rod 113 at the top of the position where the filter element 109 needs to be replaced is rotated, so that the threaded rod 113 drives the piston 112 to move downward and close the liquid outlet 111. At this time, the threaded cover 114 is driven to rotate so that it is threadedly connected with the threaded ring 115 until the threaded cover 114 is disengaged from the threaded ring 115. At this time, the threaded cover 114 can be pulled up, and the liquid inlet cover 110 will drive the filter element 109 to move upward and disengage from the top of the top cover 103, so that the filter element 109 can be replaced.

[0030] Working principle: When the utility model is in use, the finished hydrogen peroxide product first enters the Y-type filter 1 through the pipeline, and the larger solid impurities in the liquid are removed by the Y-type filter 1, and then the product is pumped to the primary filter 3 and the secondary filter 4 by the centrifugal pump 2. The primary filter 3 and the secondary filter 4 further improve the filtering efficiency and filtering accuracy of the hydrogen peroxide, which can ensure the safety of the production process and the stability of product quality. The two centrifugal pumps 2 are not started at the same time, so that the long-term interruption of the filtration link of the finished hydrogen peroxide product due to the failure of the centrifugal pump 2 can be avoided, so as not to affect the final delivery;

[0031] When the primary filter 3 and the secondary filter 4 are in use, hydrogen peroxide enters the four-way pipe 106 through the liquid inlet pipe 105, and flows from the liquid outlet hole 111 at the top of the four-way pipe 106 to the liquid inlet cover 110. Since the threaded cover 114 forms a seal with the four-way pipe 106, and the liquid inlet cover 110 forms a seal with the top of the installation tube 107 and the surface of the four-way pipe 106, respectively, the water discharged from the top of the four-way pipe 106 will enter the installation tube 107 and the inner partition mesh tube 108 through the hole in the middle of the liquid inlet cover 110. At the intermediate position, as the hydrogen peroxide in the four-way pipe 106 is continuously pumped in, the pressure in the four-way pipe 106 increases, and the hydrogen peroxide passes through the filter element 109, and has a filtering effect on the hydrogen peroxide. After the hydrogen peroxide passes through the filter element 109, it will pass through the installation cylinder 107 and the inner partition mesh tube 108 and finally fall to the bottom of the filter barrel 102, and be discharged from the liquid outlet pipe 104. The hydrogen peroxide is filtered by the filter element 109 in the primary filter 3 and the secondary filter 4, which can effectively remove impurities in the hydrogen peroxide.

[0032] After long-term use, impurities will accumulate in the filter element 109 and affect the filtering effect of the filter element 109. At this time, reduce the power of the centrifugal pump 2 and observe the changes in the values ​​of the pressure gauges at one end of the primary filter 3 and the secondary filter 4. When the pressure gauge values ​​are lower than the safe value, turn the threaded rod 113 at the top of the position where the filter element 109 needs to be replaced, so that the threaded rod 113 is threadedly connected to the top of the four-way pipe 106, and drives the piston 112 to move downward, so that the piston 112 closes the liquid outlet 111. At this time, the four-way pipe 106 at this position no longer transports hydrogen peroxide to the liquid inlet cover 110. At this time, hold the handle 116 with both hands, and use the handle 116 to drive the threaded cover 114 to rotate so that it is threadedly connected to the threaded ring 115 until the threaded cover 114 is separated from the threaded ring 115. At this time, The threaded cover 114 can be pulled up to cooperate with the liquid inlet cover 110 to drive the filter element 109 to move upward and detach from the top of the top cover 103, so that the filter element 109 can be replaced. The new filter element 109 is reinserted into the position between the installation cylinder 107 and the inner partition mesh tube 108, and the threaded cover 114 is threadedly connected with the threaded ring 115. Then, the threaded rod 113 is rotated in the opposite direction, so that the threaded rod 113 drives the piston 112 to move upward until the hydrogen peroxide inside the four-way pipe 106 can flow to the liquid inlet cover 110 through the liquid outlet hole 111. At this time, the replacement of the filter element 109 is completed, thereby achieving the purpose of facilitating online replacement of the filter element 109. The primary filter 3 and the secondary filter 4 can optimize the filtering effect and simplify the maintenance process, thereby improving the reliability and stability of the system.
