Description

Technical Field

[0001] The utility model relates to the technical field of industrial filters, in particular to an industrial filter with an internal reverse osmosis membrane that can be easily replaced. Background Art

[0002] Reverse osmosis, also known as reverse osmosis, is a membrane separation operation that uses pressure difference as the driving force to separate the solvent from the solution. Pressure is applied to the liquid on one side of the membrane. When the pressure exceeds its osmotic pressure, the solvent will reversely permeate in the direction of natural osmosis, thereby obtaining the permeated solvent, i.e., the permeate, on the low-pressure side of the membrane; and a concentrated solution, i.e., the concentrate, on the high-pressure side. Currently, industrial filters are equipped with automatic reverse osmosis devices with reverse osmosis membranes to improve filtration.

[0003] However, after long-term use, the reverse osmosis membrane in the filter needs to be disassembled and replaced and cleaned. However, most of the existing installation structures fix the reverse osmosis device in the filter through a fixed structure. During disassembly and assembly, manual disassembly and assembly work is required through tools. The disassembly structure is relatively cumbersome, and the disassembly efficiency of the reverse osmosis device is low, which affects the normal operation of the filter. Therefore, we propose an industrial filter that is easy to replace the internal reverse osmosis membrane in order to solve the above problems. Utility Model Content

[0023] The first slide plate 5, the bottom plate 6, the connecting rod 7 and the sealing plate 8 form a placement rack structure in the filter box 1, so as to fix the reverse osmosis membrane, and the filter box 1 forms a slide movable structure with the first slide plates 5 on both sides of the placement rack through the first slide groove 2, which is convenient for taking out and installing the placement rack.

[0024] The spring pieces 11 are arranged at equal intervals in the fixing grooves 10 of the bottom plate 6 and the sealing plate 8 , so that the two ends of the reverse osmosis membrane are limited and fixed by the spring pieces 11 and the fixing grooves 10 .

[0025] The first clamping block 15 and the second clamping block 16 each form a movable structure in the fixed plate 12 through the first rack 14 and the rack rod 13, so that the first clamping block 15 and the second clamping block 16 can move up and down through the rotation of the rack rod 13, and the bottom of the first clamping block 15 and the second clamping block 16 each form an elastic structure in the fixed plate 12 through the spring 17 and the connecting plate 18, so that the first clamping block 15 and the second clamping block 16 are pushed outward by the spring 17 without being subjected to force, and maintain connection with the first clamping slot plate 4 on the filter box 1.

[0026] The first clamping block 15, the second clamping block 16 and the first clamping slot plate 4 form a snap connection, so that the internal placement rack can be fixed in the filter box 1, and the first clamping slot plate 4 is a semicircular structure, so that the first slides 5 on both sides of the placement rack will not be blocked when pulled out.

[0027] The second rack 19 is disposed on the upper side of the rack rod 13 and the second rack 19 penetrates the fixed plate 12 to provide a gripping rod 20 , so that the rack rod 13 can be driven to rotate by the activity of the second rack 19 .

[0028] Working principle: When using the industrial filter that is convenient for replacing the internal reverse osmosis membrane, first, when the reverse osmosis membrane in the filter box 1 needs to be replaced, the staff member holds the handle at the front end of the fixed plate 12 in the filter box 1, then inserts the finger into the grip 20, and then holds the handle, which will cause the grip 20 to drive the second rack 19 to move backward, and the second rack 19 moving backward will drive the rack rod 13 inside the fixed plate 12 to rotate, and the rotation of the rack rod 13 will drive the first racks 14 on both sides to rotate, so that the first clamping block 15 and the second clamping block 16 connected to the two ends of the first rack 14 are driven to move inward, and the first clamping block 15 and the second clamping block 16 move inward to disengage from the clamping slot in the first clamping slot plate 4 on the outer filter box 1, thereby unlocking the placement frame composed of the internal first clamping slot plate 4, the first slide plate 5, the bottom plate 6, the connecting rod 7, and the sealing plate 8.

[0029] Then pull the handle so that the placement rack is pulled out of the filter box 1 through the chute structure composed of the first slide plates 5 on both sides and the first chute 2 in the filter box 1, until the reverse osmosis membrane is pulled out of the filter box 1 as a whole, and then come to the side of the filter box 1, push the reverse osmosis membrane upward, and then the reverse osmosis membrane can be removed from the placement rack and replaced with a new one;

[0030] When replacing a new reverse osmosis membrane, align the two ends of the reverse osmosis membrane with the fixing grooves 10 on the bottom plates 6 at both ends of the placement rack and the sealing plates 8, and then press the reverse osmosis membrane into the fixing grooves 10, which will cause the spring sheets 11 in the fixing grooves 10 to squeeze and fix the two ends of the reverse osmosis membrane, and then hold the handle at the front end of the fixing plate 12 to push the placement rack into the filter box 1 until the sealing plate 8 seals the front end, and at the same time, the connecting through hole 9 in the rear bottom plate 6 will also be connected to the clean water outlet 3 at the bottom of the filter box 1, and then release the pull on the grip rod 20, so that the first clamping block 15 and the second clamping block 16 can be driven by the reaction force of the bottom spring 17 to enter the first clamping slot plate 4, thereby completing the connection of the snap structure, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
