Description

Technical Field

[0001] The invention relates to the technical field of water coolers, and in particular to a self-cleaning split-flow cooling water filter for water coolers. Background Art

[0002] Laser cutting equipment requires a chiller to circulate water to cool the laser generator inside the equipment and control the operating temperature of the laser generator so that the laser generator can maintain normal operation for a long time. During the long-term operation of the laser equipment, the laser generator will continuously generate high temperature. Excessive temperature will affect the normal operation of the laser generator, so it is very necessary to maintain the purity of the cooling water in the water circulation in the chiller. However, as the working time increases, dust, sediment, microorganisms and their spores from the air will be brought into the circulation system of the water chiller with the air, and even insects will appear, causing blockage of the pipes in the heat exchange system and water circulation system.

[0003] Most existing cooling water filters clean the cooling water by adding a filter screen inside the filter barrel. However, this method has the following drawbacks:

[0004] (1) In order to achieve a good cleaning effect, the pore size of the filter is relatively small. Therefore, the water output efficiency of only one filter component is relatively low. In addition, due to the slow filtration efficiency of the filter, the amount of water above the filter increases continuously, which will cause the filter to bear a heavy load. If the filter is detachable, it is very likely to cause the filter to fall off.

[0005] (2) After the filter has been used for a period of time, some microorganisms will adhere to the barrel body 1, causing secondary pollution to the filtered water. The barrel body needs to be cleaned, and the existing filter cleaning work mostly involves disassembling the filter assembly and then manually cleaning it. Summary of the Invention

[0006] The purpose of the present invention is to provide a self-cleaning diversion cooling water filter for a water-cooled machine to solve the technical problems that the water output efficiency of the existing technology using only one filter component is relatively low. In addition, due to the slow filtration efficiency of the filter mesh, the amount of water above the filter mesh continues to increase, which will cause the filter mesh to bear a relatively large load. In addition, the existing filter cleaning work mostly requires disassembling the filter assembly and then manually cleaning it.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] like Figure 1As shown, the present invention provides a self-cleaning shunt cooling water filter for a water-cooled machine, the cooling water filter specifically comprising:

[0039] The barrel body 1 has a cylindrical inner wall and is provided with a water inlet 2 and a water outlet.

[0040] The stepped diverter filter assembly 3 is installed inside the barrel body 1 in a circular spiral manner. The head and tail of the stepped diverter filter assembly 3 have a height difference, and the head and tail of the stepped diverter filter assembly 3 are closed and connected.

[0041] The driving assembly 4 is arranged at the upper end of the barrel body 1 and can push the stepped diverter filter assembly 3 to move in a rotating manner up and down, so that the stepped diverter filter assembly 3 and the inner wall of the barrel body 1 can be frictionally cleaned.

[0042] Among them, the cooling water flows to the stepped diversion filter component 3 through the water inlet 2, and the cooling water is filtered through the stepped diversion filter component 3, and the overflowing water flows through the stepped diversion filter component 3 with gradually decreasing height in a spiral manner to achieve diversion filtering treatment.

[0043] As one of the innovations of this embodiment, the filter assembly in this embodiment is not a whole filter module laid horizontally in the barrel body, but is divided into multiple filter modules of different heights. When the filtration speed of one of the filter modules is lower than the water inlet speed, the overflowing water is transferred to the next filter module to continue the filtration operation, and the operation is repeated, thereby realizing a diversion-type filtration operation, reducing the filtration pressure of each filter module, and increasing the service life of the filter mesh bag. In addition, the surplus water flow is transferred to other filter mesh bags to continue the filtration work, thereby speeding up the water output efficiency and meeting the water output rate of different needs.

[0044] In addition, the filter module in this embodiment also plays the role of cleaning the inner wall of the barrel body. The existing entire filter module laid horizontally in the barrel body affects the cleaning work of the barrel body. The filter module in this embodiment is not fixedly installed in the barrel body, but can be rotated up and down along the inner wall of the barrel body. Therefore, after repeated reciprocating driving, the self-cleaning work of the inner wall of the barrel body can be achieved.

[0045] Specifically, such as Figure 2 As shown, the stepped diversion filter assembly 3 includes a supporting column 31 arranged on the driving assembly 4, and layered filter elements 32 stacked up and down on the side curved surface of the supporting column 31, and the edges of two adjacent layered filter elements 32 are sealed and connected so that all the layered filter elements 32 are distributed on the side curved surface of the supporting column 31 in a spiral stepped manner, and the layered filter element 32 at the highest position is connected to the layered filter element 32 at the lowest position through a closing plate 33.

[0046] The water overflowing from the previous layered filter element 32 is continuously filtered through the next layered filter element 32 to achieve diversion filtration.

[0047] The stepped diversion filter assembly 3 of this embodiment is distributed in a spiral shape, so the water flow overflowing from the layered filter element 32 is also distributed in a spiral shape. Therefore, the fluidity of the water flow is large, and the filtering efficiency during filtration can naturally be improved.

[0048] In addition, as a preferred embodiment, each layered filter element 32 is the same size, and the edges of two adjacent layered filter elements 32 distributed up and down are vertically connected and sealed, and the layered filter element 32 at the highest position is connected to the layered filter element 32 at the lowest position through a closing plate 33, and the closing plate 33 is vertically distributed. In this way, the stepped diversion filter assembly 3 can layer the barrel body 1, and the water flow from the water inlet 2 falls into the lower layer of the barrel body 1 after being filtered by the stepped diversion filter assembly 3.

[0049] In order to further ensure that the water flows in a spiral manner from all the layered filter elements 32 in sequence, the layered filter element 32 includes an inclined fan-shaped panel 321 and a fan-shaped impact hole 322 provided on the fan-shaped panel 321. A filter bag 323 is installed in the fan-shaped impact hole 322, wherein the inclination direction of the fan-shaped panel 321 is inclined downward so that the water flows along the inclined fan-shaped panel 321 to the next lower filter bag 323.

[0050] When the water flow in the water inlet 2 is filtered by the highest layered filter element 32, the overflowing water flow is transferred from the inclined fan-shaped panel 321 to the next lower layered filter element 32, and so on, thereby diverting and filtering the water flows with different water inlet rates.

[0051] In order to further realize the inclined diversion effect of the fan-shaped panel 321, the center position of the fan-shaped impact hole 322 deviates from the center position of the fan-shaped panel 321, and the center position of the fan-shaped impact hole 322 is close to the high side of the fan-shaped panel 321, so that the low side of the fan-shaped panel 321 forms a diversion slope. Therefore, the water overflowing from the filter bag 323 moves through the diversion slope to the filter bag 323 of the next layered filter element 32.

[0052] In addition, if Figure 3As shown, the outer side of the fan-shaped impact hole 322 is provided with an enclosing downward pressure sinking groove 324, the opening of the filter bag 323 is installed in the downward pressure sinking groove 324, and the downward pressure sinking groove 324 is provided with a pressure plate 325 that can be embedded in the downward pressure sinking groove 324. The pressure plate 325 squeezes the opening of the filter bag 323, and the pressure plate 325 is provided with an extension ring panel 326 facing the inner side of the fan-shaped impact hole 322. The opening of the filter bag 323 is connected to the extension ring panel 326 through a hook 327 to fix the opening of the filter bag 323.

[0053] The vertical section of the pressure plate 325 is a T-shaped structure, and the width of the upper plate of the pressure plate 325 is greater than the width of the lower pressure groove 324.

[0054] When the water cooler is applied to the laser cutting equipment in this embodiment, the cooling water flows directly from the water reservoir into the laser generator for water cooling to control the operating temperature of the laser generator. As the working time increases, dust, sediment, microorganisms and their spores in the air will be brought into the circulation system of the water cooler along with the air, and even insects may appear. The filter bag 323 is mainly used to filter out such impurities.

[0055] In order to achieve repeated use of the filter bag 323, the filter bag 323 in this embodiment is installed in a movable manner, and a pressure plate 325 is used to squeeze the opening of the filter bag 323. The specific working principle is as follows:

[0056] When the water flow in the filter bag 323 increases, the filter bag 323 is forced to sag, and the opening of the filter bag 323 is connected to the extension ring panel 326 through the hook 327. The stressed filter bag 323 applies downward pressure to the pressure plate 325, thereby improving the installation stability of the pressure plate 325 and effectively preventing the filter bag 323 from falling due to the gravity of the water flow.

[0057] Therefore, in order to further ensure that the water flowing into the barrel body 1 from the water inlet 2 is filtered, in addition, an arc-shaped sealing plate 5 is provided on the outer side of the fan-shaped panel 321 and the closing plate 33. The arc-shaped sealing plates 5 of all fan-shaped panels 321 and the closing plate 33 form a closed elliptical structure. The height of the arc-shaped sealing plate 5 is greater than the thickness of the fan-shaped panel 321. The arc-shaped sealing plate 5 makes the fan-shaped panel 321 in close contact with the inner surface of the barrel body 1, so that the water can only flow to the lower end of the barrel body 1 after being processed by the filter bag 323.

[0058] In this embodiment, the water flowing into the barrel body 1 from the water inlet 2 first passes through the filter bag 323 at the highest position. Since the filter mesh of the filter bag 323 is relatively small, the diameter of the filter hole is 0.4 mm. Therefore, when the filtration efficiency of the filter bag 323 is lower than the water inlet rate of the water inlet 2, the water volume in the filter bag 323 continues to increase until it overflows the filter bag 323, and the overflowed water continues to flow into the next lower filter bag 323.

[0059] Each sector panel 321 has only the filter bag 323 as a water outlet, thereby ensuring that the water flowing to the water outlet is filtered and cleaned, thereby ensuring the cleanliness of the cooling water in the water cooler.

[0060] After the filter has been used for a period of time, some microorganisms will adhere to the barrel body 1, causing secondary pollution of the filtered water. The barrel body needs to be cleaned, and the existing filter cleaning work mostly involves disassembling the filter assembly and then manually cleaning it.

[0061] In order to realize automatic cleaning of the barrel body, in this embodiment, the stepped diversion filter component 3 is provided with a detachable manner, and is driven by the driving component 4 to move in an upward and downward rotational manner.

[0062] Specific examples Figure 4 and Figure 5 As shown, the driving assembly 4 includes a vertical column 41 arranged inside the barrel body 1, and a linear driving member 42 arranged above the barrel body 1. The lower end of the vertical column 41 is provided with a threaded column 43, and the inner wall of the supporting cylinder 31 is provided with two arc-shaped curved plates 6 that are symmetrical about the center of the supporting cylinder 31. The supporting cylinder 31 is sleeved on the vertical column 41, and the supporting cylinder 31 is driven by the linear driving member 42 to rotate up and down along the threaded column 43 through the arc-shaped curved plate 6.

[0063] A push sleeve 44 is movably provided at the upper end of the bearing cylinder 31. The working shaft of the linear drive 42 is connected to the push sleeve 44. The linear drive 42 pushes the push sleeve 44 and the bearing cylinder 31 to move up and down synchronously. At the same time, the bearing cylinder 31 rotates around the threaded column 43 while moving up and down.

[0064] The inner diameter of the upper end of the push sleeve 44 is the same as the diameter of the vertical column 41. When the push sleeve 44 is outside the vertical column 41, it is in close contact with the vertical column 41. The inner surface of the lower end of the push sleeve 44 is provided with an inner convex snap ring 45, and the outer surface of the upper end of the support column 31 is provided with an annular groove 46 that matches the inner convex snap ring 45. The push sleeve 44 and the support column 31 are movably connected through the inner convex snap ring 45 and the annular groove 46.

[0065] The linear drive component 42 can be a pushing cylinder or a linear motor, which is mainly used to push the push sleeve 44 to move linearly up and down along the vertical column 41. Since the push sleeve 44 and the supporting column 31 are movably connected through the inner convex retaining ring 45 and the annular groove 46, the supporting column 31 moves up and down synchronously with the push sleeve 44. At the same time, since the inner wall of the supporting column 31 is provided with an arc-shaped curved plate 6, the supporting column 31 moves up and down while also rotating around the threaded column 43 through the arc-shaped curved plate 6.

[0066] Therefore, when the supporting column 31 moves up and down, it can also rotate synchronously, so the arc-shaped sealing plate 5 and the inner wall of the barrel body 1 have a friction effect to achieve self-cleaning, and the cleaned impurities can be discharged through the water outlet. A sewage outlet and a circulation pipe are set on the pipe connected to the water outlet.

[0067] In summary, when filtering cooling water, this embodiment uses a stepped diversion filter assembly to make the water flow in a spiral shape, and divides it into multiple filter units during the spiral flow process, thereby reducing the filtration pressure of each filter unit, thereby improving the filtration efficiency and meeting the water demand of the water cooler. At the same time, the filter assembly is also used as a cleaning tool. The filter assembly generates friction with the inner wall of the barrel through up and down rotational movement to achieve self-cleaning of the barrel without the need for manual cleaning.

[0068] The above embodiments are merely exemplary embodiments of the present application and are not intended to limit the scope of the present application. The scope of protection of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and scope of protection of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present application.
