Description

Technical Field

[0001] The present invention relates to the field of purification technology, and in particular to a combined multi-stage purification device. Background Art

[0002] A water purifier, also known as a water purification machine or water quality purifier, is a water treatment device that deeply filters and purifies water quality according to the usage requirements of water. Generally, the water purifier mentioned usually refers to a small purifier for household use. The core technology thereof is the filter membrane in the filter element device, and the main technologies come from three types: ultrafiltration membrane, RO reverse osmosis membrane, and nanofiltration membrane.

[0003] Due to the large differences in water quality in different regions, and many old communities or rural areas still use iron pipes to transport water sources. Long-term use results in a relatively high heavy metal content in the water quality. As a result, more and more multi-stage water purification devices are installed in households. Currently, most water purification devices often connect several purification cylinders in series and then directly place them in a cabinet, or when a single purification cylinder is damaged later, all the purification cylinders need to be replaced, resulting in increased costs and inconvenience in replacing the filter cylinders later.

[0004] In view of the above problems, the inventor proposes a combined multi-stage purification device to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] ReferenceFigures 1-6 , a combined multi-stage purification device, including a box body 1, a sealing door 2, four purification cylinders 3, and an assembly component. Both ends of each purification cylinder 3 are fixedly connected with pipelines. T-shaped gaskets 25 are fixedly installed on the surface of each pipeline and the end of the corresponding purification cylinder 3, increasing the sealing performance at the connection between each purification cylinder 3 and the corresponding liquid transfer pipe 4 or liquid inlet pipe 6 or liquid outlet pipe 5 below. An arc-shaped positioning plate 26 is attached to the surface of each purification cylinder 3, and the arc-shaped positioning plate 26 is fixedly installed on the inner bottom of the box body 1. When installing the purification cylinder 3, the surface of the purification cylinder 3 can be closely attached to the inner side of the corresponding arc-shaped positioning plate 26. At this time, the pipelines of each purification cylinder 3 can be aligned with the corresponding liquid transfer pipe 4 or liquid inlet pipe 6 or liquid outlet pipe 5 below, and then sliding downward can quickly insert the pipeline into the corresponding liquid transfer pipe 4 or liquid inlet pipe 6 or liquid outlet pipe 5 below.

[0032] The sealing door 2 is slidably installed on the surface of the box body 1, and two limit guiding components are provided between the sealing door 2 and the box body 1. The limit guiding component includes a sliding groove 21 opened on the front side of the box body 1. A slider 22 is slidably connected in the sliding groove 21, and the slider 22 is fixedly installed on the surface of the sealing door 2. A guiding rod 23 slidably penetrates through the top of the slider 22, and the guiding rod 23 is vertically fixedly installed in the sliding groove 21, enabling the sealing door 2 to slide vertically on the surface of the box body 1 and not fall off at the same time.

[0033] The four purification cylinders 3 are installed in the box body 1 in a linear array, and the four purification cylinders 3 are sequentially connected with liquid transfer pipes 4 between every two of them. The liquid transfer pipe 4 in the middle fixedly penetrates through the bottom of the box body 1, and the other two liquid transfer pipes 4 movably penetrate through the top of the box body 1. The bottom parts of the two purification cylinders 3 at the left and right ends are respectively connected with a liquid inlet pipe 6 and a liquid outlet pipe 5, and both the liquid inlet pipe 6 and the liquid outlet pipe 5 fixedly penetrate through the bottom of the box body 1. When water flow is introduced, the water flow flows in from the liquid inlet pipe 6, and then sequentially passes through the first purification cylinder 3, the upper first liquid transfer pipe 4, the second purification cylinder 3, the lower liquid transfer pipe 4, the third purification cylinder 3, the upper second liquid transfer pipe 4, and the fourth purification cylinder 3 from left to right. Thus, under the purification of the filter element inside each purification cylinder 3, the purified liquid finally flows out from the liquid outlet pipe 5, completing the multi-stage purification of the liquid.

[0034] The assembly component includes a screw rod 7 threaded through the top of the box body 1. An idler wheel 8 is fixedly sleeved on the outer wall of the screw rod 7, and a knob 10 is fixedly installed at the top of the screw rod 7. Two convex blocks 27 are fixedly installed on the side of the knob 10, and the two convex blocks 27 are symmetrically arranged, enabling the staff to rotate the knob 10 more easily. A connecting plate 9 is movably sleeved on the outer wall of the idler wheel 8, and the connecting plate 9 is fixedly installed at the top of the two upper liquid delivery pipes 4. After inserting the end of each purification cylinder 3 downward into the corresponding liquid delivery pipe 4 or liquid inlet pipe 6 or liquid outlet pipe 5, by rotating the screw rod 7 through the knob 10 to make it spiral downward on the top of the box body 1, and then using the rotation of the idler wheel 8, the connecting plate 9 and the two upper liquid delivery pipes 4 above can be driven to move downward synchronously until the pipe orifices of the two upper liquid delivery pipes 4 are all sleeved on the upper pipe ports of the corresponding purification cylinders 3, and each purification cylinder 3 is continuously pushed downward to be tightly pressed against the inner bottom wall of the box body 1, so as to realize the connection between each purification cylinder 3 and the corresponding liquid delivery pipe 4 or liquid inlet pipe 6 or liquid outlet pipe 5, thereby achieving the effect of quickly assembling multiple purification cylinders 3, improving the assembly efficiency of the device, and being able to achieve the effect of disassembling and assembling a single purification cylinder 3, reducing the use cost, and facilitating subsequent maintenance and replacement.

[0035] An installation component is provided between the connecting plate 9 and the box body 1. The installation component is used to install the box body 1 on the wall. The installation component includes an installation track 11 slidably installed on the back of the box body 1. Two ear plates 12 are symmetrically and fixedly installed at the top and bottom of the installation track 11. Before use, the installation track 11 can be fixed at the designated installation position on the wall by sequentially passing multiple screws or rivets through each ear plate 12.

[0036] And a T-shaped guide bar 13 is slidably inserted at the end of the installation track 11. The T-shaped guide bar 13 is fixedly installed on the back of the box body 1, and a right-angle positioning plate 14 is slidably inserted together with the top of the installation track 11 at the top of the T-shaped guide bar 13. A limiting block 24 is slidably sleeved on the outer wall of the right-angle positioning plate 14, and the limiting block 24 is fixedly installed on the back of the box body 1, effectively ensuring the stability of the right-angle positioning plate 14 during the up and down sliding process.

[0037] And the other end of the right-angle positioning plate 14 is fixedly installed on the outside of the connecting plate 9. Positioning grooves 15 are opened at the top of the T-shaped guide bar 13 and the top of the installation track 11, and the positioning grooves 15 are engaged with or separated from the right-angle positioning plate 14. Before assembling multiple purification cylinders 3, first insert the T-shaped guide bar 13 horizontally into the installation track 11, and the box body 1 can be preliminarily positioned on the wall. Then when rotating the screw rod 7 to drive the connecting plate 9 to move downward, the right-angle positioning plate 14 can also be driven to move downward synchronously until it passes through the positioning groove 15 at the top of the installation track 11 and is inserted into the positioning groove 15 at the top of the T-shaped guide bar 13, and the T-shaped guide bar 13 and the installation track 11 can be fixed, and the installation and fixation between the box body 1 and the wall can be completed.

[0038] A positioning component is provided between the connecting plate 9 and the sealing door 2. The positioning component is used to fix the sealing door 2 on the surface of the box body 1. The positioning component includes a clamping block 17 rotatably mounted on the top of the sealing door 2 through a self-locking rotating shaft 16. A right-angle clamping plate 18 slidably penetrates through the clamping block 17, and the right-angle clamping plate 18 is fixedly installed on the outside of the connecting plate 9. A clamping groove 20 and a clamping hole 19 are respectively formed in the top of the box body 1 and the top of the clamping block 17. After the box body 1 and the installation track 11 are initially positioned, under the guidance of the two limit guiding components, the sealing door 2 is pushed upward until the sealing door 2 and the box body 1 completely overlap. Subsequently, the clamping block 17 is flipped upward until it fits against the top of the box body 1. Then, when the above-mentioned screw 7 rotates, it can also drive the right-angle clamping plate 18 to move downward until it passes through the clamping hole 19 and inserts into the clamping groove 20, so as to fix the clamping block 17 and complete the fixation between the sealing door 2 and the box body 1.

[0039] Further explanation, the above-mentioned fixed connection, unless otherwise clearly stipulated and limited, should be understood in a broad sense. For example, it can be welding, gluing, or integrally formed setting, etc., which are common means well-known to those skilled in the art.

[0040] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
