Abstract
Description
Technical Field
[0001] This utility model relates to the field of water tank technology, and in particular to a combined stainless steel water tank. Background Technology
[0002] Modular stainless steel water tanks are widely used in water storage fields such as domestic water, fire-fighting water, and industrial water due to their advantages such as corrosion resistance, high strength, and long service life. In order to ensure the quality of the water output and prevent impurities that may exist inside the water tank (such as welding residues, rust particles, and microbial film shedding products) from entering the water-using end, a common design is to install a filter screen at the water outlet of the water tank. This filter screen filters the water flowing out of the water tank and is used to intercept suspended particulate impurities in the water.
[0003] The filter screen is usually installed inside the water outlet pipe, with its filter end (i.e., the water-facing side) facing the water inside the tank. When impurities accumulate on the filter screen and affect the water flow, it needs to be cleaned. Because the filter screen is located deep inside the tank and its structure faces the inside of the tank, cleaning operations (such as brushing) are very inconvenient. Usually, it requires operators to enter the tank or completely disassemble the filter device, which is a cumbersome, time-consuming and labor-intensive process.
[0004] To avoid frequent disassembly, backwashing is sometimes used for cleaning, which involves flushing water backwards from the outlet to try and remove impurities from the filter screen. However, because the filter screen's ends face inwards from the water tank, the backwashing water flow actually washes the impurities that were originally attached to the filter screen back into the water inside the tank. This not only fails to effectively remove the impurities but also causes them to redistribute within the tank, resulting in secondary water pollution. Utility Model Content
[0005] In view of the aforementioned problems with the inconvenience of cleaning existing filters, this utility model is proposed.
[0006] Therefore, the purpose of this utility model is to provide a modular stainless steel water tank, which allows for cleaning without disassembling the filter screen and avoids secondary pollution of the water tank.
[0007] To solve the above technical problems, this utility model provides the following technical solution: a combined stainless steel water tank, comprising a combined water tank with an inlet end and an outlet end, an outlet pipe installed at the outlet end of the combined water tank, a cleaning chamber welded to the end of the outlet pipe away from the combined water tank, a connecting hole provided on both the front and back of the cleaning chamber, a filter connecting pipe welded to the end face of the cleaning chamber away from the outlet pipe and directly opposite the connecting hole, a stainless steel filter screen fixed inside the filter connecting pipe near the end of the cleaning chamber, and a filter assembly detachably installed at the end of the filter connecting pipe away from the outlet pipe.
[0008] A drain pipe is welded to the drain outlet at the bottom of the cleaning chamber. A vertical chamber is welded to the middle of the top of the cleaning chamber. A chamber cover is installed at the open end of the vertical chamber away from the cleaning chamber by screws. A column is vertically raised and lowered inside the vertical chamber. A silicone brush bristle is fixedly connected to one end of the column inside the cleaning chamber, and the bristle end of the silicone brush bristle is in contact with the end of the stainless steel filter screen near the water outlet pipe.
[0009] As an improved technical solution, guide rails are fixed on both sides inside the cleaning chamber, and sliding blocks that slide on the guide rails are installed on both sides of the silicone brush bristles. The silicone brush bristles move vertically and linearly under the limiting sliding action of the two guide rails.
[0010] As an improved technical solution, shallow grooves are provided on both sides of the vertical compartment and both sides of the inner wall of the vertical compartment. A magnet is fixedly connected to the end of the column away from the silicone brush bristles. A magnet is vertically limited and slidably installed on both sides of the magnet, and the opposite surfaces of the magnet and the magnet are in a magnetic adsorption state.
[0011] As an improved technical solution, two slide rails are symmetrically installed on both sides of the vertical compartment with the second magnet as the symmetrical point. A slider is slidably installed on the slide rail. A horizontal bar is fixed between the two sliders on the same side, and the second magnet is fixed in the middle of the horizontal bar near the vertical compartment.
[0012] As an improved technical solution, the filtration assembly includes an installation tube, and a filter element is installed inside the installation tube. The filter element is composed of an activated carbon filter layer, an RO reverse osmosis membrane, an ultrafiltration membrane, and a filter screen.
[0013] As an improved technical solution, a first flange is fitted to the end of the water outlet pipe away from the cleaning chamber and the end of the filter connecting pipe away from the cleaning chamber, and a second flange is fitted to both ends of the installation pipe, and the diameters of the first flange and the second flange are the same.
[0014] After adopting the above technical solution, the beneficial effects of this utility model are:
[0015] 1. In this utility model, water is filtered once through a stainless steel filter screen to remove impurities, and then filtered a second time through a filter element to remove microorganisms and bacteria. The dual filtration effect improves the cleanliness of the discharged water. The filter assembly is detachably installed on the filter pipe via a flange, making it easy to replace the entire filter assembly.
[0016] 2. This utility model can clean the filter end of the stainless steel filter screen by directly driving the silicone brush bristles to rise and fall. It can clean the stainless steel filter screen conveniently and quickly without disassembling the filter device, which greatly simplifies the maintenance process, reduces labor intensity and operational risks. In addition, the cleaned impurities are directly discharged from the drain pipe through the water flow and will not flow back into the combined water tank, preventing secondary pollution of the water inside the combined water tank when cleaning the stainless steel filter screen.
[0017] 3. In this utility model, the horizontal bar is guided to slide on the slide rail by a slider, ensuring that the second magnet moves vertically in a linear manner, thereby ensuring the magnetic attraction effect between the second magnet and the first magnet. At the same time, due to the magnetic attraction between the second magnet and the first magnet, when the horizontal bar moves downward, the first magnet will also drive the column to move downward, that is, drive the silicone brush bristles to move downward. Conversely, when the horizontal bar is driven upward, the column moves upward. This allows the silicone brush bristles inside to be directly controlled from the outside to move up and down, ensuring that the column and silicone brush bristles are in a sealed environment, preventing dust from entering the interior of the vertical compartment and causing secondary pollution during cleaning.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0027] Example 1
[0028] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a combined stainless steel water tank. This combined stainless steel water tank includes a combined water tank 1 with an inlet end and an outlet end. An outlet pipe 2 is installed at the outlet end of the combined water tank 1. A cleaning chamber 4 is welded to the end of the outlet pipe 2 away from the combined water tank 1. A connecting hole 42 is opened on both the front and back of the cleaning chamber 4. The interior of the outlet pipe 2 is connected to the interior of the cleaning chamber 4 through the connecting hole 42. A filter connecting pipe 5 is welded to the end face of the cleaning chamber 4 away from the outlet pipe 2 and at the position opposite to the connecting hole 42. A stainless steel filter screen 6 is fixed inside the filter connecting pipe 5 near the end of the cleaning chamber 4. A filter assembly 7 is detachably installed at the end of the filter connecting pipe 5 away from the outlet pipe 2.
[0029] A drain pipe 43 is welded to the drain outlet at the bottom of the cleaning chamber 4, and a drain valve is installed on the drain pipe 43. A vertical chamber 41 is welded to the middle of the top of the cleaning chamber 4. A chamber cover 44 is installed on the open end of the vertical chamber 41 away from the cleaning chamber 4 by screws. A column 9 is vertically raised and lowered inside the vertical chamber 41, and the lower end of the column 9 is located inside the cleaning chamber 4. A silicone brush bristle 8 is fixedly connected to the end of the column 9 inside the cleaning chamber 4, and the brush bristle end of the silicone brush bristle 8 is in contact with the end face of the stainless steel filter screen 6 near the water outlet pipe 2.
[0030] The cleaning chamber 4 has guide rails 10 fixed on both sides. The silicone brush bristles 8 have sliding blocks installed on both sides of the guide rails 10, and the silicone brush bristles 8 move vertically and linearly under the limiting sliding action of the two guide rails 10.
[0031] Shallow grooves 12 are provided on both sides of the vertical compartment 41 and on both sides of the inner wall of the vertical compartment 41. A magnet 11 is fixedly connected to the end of the column 9 away from the silicone bristles 8, and both sides of the magnet 11 are located inside the shallow grooves 12 on the inner wall of the vertical compartment 41. A magnet 23 is vertically limited and slidably installed on both sides of the magnet 11, and the opposite surfaces of the magnet 23 and the magnet 11 are in a magnetic adsorption state. At the same time, the side of the magnet 23 closer to the vertical compartment 41 is located inside the shallow grooves 12 on the outside of the vertical compartment 41. When the horizontal bar 15 moves downward, the column 9 will also move downward through the magnet 11, that is, the silicone bristles 8 will move downward. Conversely, when the horizontal bar 15 is driven upward, the column 9 moves upward. This allows the silicone bristles 8 inside to be raised and lowered directly from the outside, ensuring that the column 9 and the silicone bristles 8 are in a sealed environment, and preventing dust from entering the interior of the vertical compartment 41 during cleaning and causing secondary pollution.
[0032] Two slide rails 14 are symmetrically installed on both sides of the vertical compartment 41 with magnet 2 13 as the symmetrical point. Slider 16 is slidably installed on the slide rail 14. A horizontal bar 15 is fixed between the two sliders 16 on the same side. Magnet 2 13 is fixed in the middle of the horizontal bar 15 near the vertical compartment 41. The horizontal bar 15 is guided to slide on the slide rail 14 by the slider 16 to ensure that magnet 2 13 moves vertically in a linear manner, thereby ensuring the magnetic attraction effect between magnet 2 13 and magnet 11.
[0033] During use, the stainless steel filter screen 6 can be cleaned by simply driving the silicone brush bristles 8 to rise and fall. The stainless steel filter screen 6 can be cleaned conveniently and quickly without disassembling the filter device, which greatly simplifies the maintenance process, reduces labor intensity and operational risks. In addition, the cleaned impurities are discharged directly through the drain pipe 43 by the water flow and will not flow back into the combined water tank 1, preventing secondary pollution of the water inside the combined water tank 1 when cleaning the stainless steel filter screen 6.
[0034] Example 2
[0035] Reference Figure 2 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the filter assembly 7 includes an installation tube 71, and a filter element 73 is installed inside the installation tube 71. The filter element 73 is composed of an activated carbon filter layer, an RO reverse osmosis membrane, an ultrafiltration membrane and a filter screen plate, and the activated carbon filter layer is located at one end near the outlet pipe 2.
[0036] The end of the water outlet pipe 2 away from the cleaning chamber 4 and the end of the filter connecting pipe 5 away from the cleaning chamber 4 are both fitted with a first flange 3. Both ends of the mounting pipe 71 are fitted with a second flange 72, and the diameters of the first flange 3 and the second flange 72 are the same. The filter assembly 7 is detachably installed on the filter connecting pipe 5 through the flange, which facilitates the overall replacement of the filter assembly 7.
[0037] During use, when the water inside the combined water tank 1 is discharged through the outlet pipe 2, the water undergoes a first filtration through the stainless steel filter screen 6 to filter out impurities in the water, and then undergoes a second filtration through the filter element 73. The second filtration can filter out microorganisms and bacteria in the water, and the dual filtration effect improves the cleanliness of the discharged water.
[0038] The remaining structure is the same as that in Example 1.
[0039] Based on embodiments 1-2, the working principle of this utility model is as follows: When it is necessary to clean the stainless steel filter screen 6, the drain valve on the drain pipe 43 is opened. When the water inside the combined water tank 1 enters the cleaning chamber 4, it will be discharged directly through the drain pipe 43. At this time, the silicone brush 8 is driven by the column 9 to move vertically back and forth. When the silicone brush 8 moves up and down, its brush tip will clean the filter end of the stainless steel filter screen 6, so that the impurities adhering to the filter end are lifted up and discharged directly outward through the drain pipe 43 with the water flow.
[0040] The process for driving the silicone brush bristles to rise and fall is as follows:
[0041] Due to the magnetic attraction between magnet 13 and magnet 11, when the horizontal bar 15 moves downward, magnet 11 will also drive the column 9 to move downward, which in turn will drive the silicone brush bristles 8 to move downward. Conversely, when the horizontal bar 15 is driven upward, the column 9 will move upward, thus enabling the silicone brush bristles 8 to be raised and lowered directly from the outside.
[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
