Detailed Implementation

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front", "back", "horizontal", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] It should be noted that the terms "horizontal" and "vertical" in this utility model are used to describe approximate positional relationships, and not strictly "horizontal plane" or "vertical plane".

[0022] like Figure 1 The image shows a preferred embodiment of a self-cleaning cooling water circulation filter, comprising: a housing 100 having an inner cavity; a high-pressure water inlet 110 at the upper end of the housing 100 communicating with the inner cavity; a discharge outlet 180 at the lower end of the housing 100 communicating with the inner cavity; a water inlet 140 on one side of the housing 100 and a water outlet 150 on the other side of the housing 100, both the water inlet 140 and the water outlet 150 communicating with the inner cavity; groove assemblies 160 arranged sequentially at intervals along the length of the bottom surface of the inner cavity; a plurality of driving devices 200 arranged sequentially at intervals along the length of the top surface of the inner cavity, each driving device 200 being directly opposite a groove; and a filter assembly connected to the driving devices 200, the filter assembly being directly opposite the groove assemblies 160, and the filter assembly being movably positioned closer to or further away from the groove assemblies 160. Furthermore, by driving the filter screen assembly through the drive device 200, the filter screen assembly can be replaced sequentially, thus achieving filter screen replacement. At the same time, the filter screen is cleaned by the high-pressure water flowing in through the high-pressure water inlet 110.

[0023] Furthermore, the number of groove assemblies 160 is preferably six, arranged sequentially from left to right on the bottom surface of the inner cavity.

[0024] Furthermore, as a preferred embodiment, a first valve 120 is provided at the high-pressure water inlet 110, and the first valve 120 is connected to a high-pressure water pipe.

[0025] Furthermore, as a preferred embodiment, such as Figure 1 As shown, the upper end of the inner cavity is also provided with several spraying components 130, and the several spraying components 130 are all connected to the first valve 120 through a pipeline.

[0026] Furthermore, as a preferred embodiment, the spray assembly 130 is preferably a spray head. Further, the spray direction of each spray head is preferably inclined from right to left.

[0027] Furthermore, as a preferred embodiment, a second valve 170 is provided at the discharge port 180, and the second valve 170 is connected to a discharge pipe.

[0028] Furthermore, in a preferred embodiment, each drive device 200 is provided with an output end 210, which is movably disposed in the inner cavity and connected to the filter assembly. Further, the output end 210 is preferably an electrically operated telescopic rod, one end of which is connected to the filter assembly.

[0029] Furthermore, in a preferred embodiment, the filter assembly includes two first filters 300, two second filters 400, and two third filters 500, which are sequentially spaced apart along the length of the inner cavity. Further, the two first filters 300, two second filters 400, and two third filters 500 are sequentially spaced apart from left to right within the inner cavity.

[0030] Furthermore, as a preferred embodiment, the two first filters 300 are preferably inserted alternately into the corresponding groove assembly 160 in sequence. Further, when one first filter 300 is inserted into the groove assembly 160, the other first filter 300 is positioned away from the groove assembly 160 via its output end 210, meaning the lower horizontal height of the other first filter 300 is greater than the upper horizontal height of the first first filter 300. In this case, the other first filter 300 does not participate in the filtration process. The operation of the second filter 400 and the third filter 500 is similar to that of the first filter 300, and will not be described further here.

[0031] Furthermore, in a preferred embodiment, the pore size of the first filter 300 is larger than that of the second filter 400, and the pore size of the second filter 400 is larger than that of the third filter 500.

[0032] Furthermore, as a preferred embodiment, the inlet 140 is connected to a cooling water pipe, and the outlet 150 is connected to an outlet pipe.

[0033] Furthermore, in a preferred embodiment, the upper horizontal height of the filter assembly is greater than the upper horizontal height of the inlet 140. Furthermore, after the cooling water flows into the inner cavity through the inlet 140, it will accumulate at the bottom of the inner cavity under the influence of gravity, but the water level will not exceed the height of the upper part of the filter assembly to prevent affecting subsequent filtration operations.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model.

[0035] The specific operating steps of this utility model's self-cleaning cooling water circulation filter are as follows:

[0036] First, close the first valve 120 and the second valve 170, and open the cooling water pipe. Cooling water from the cooling water pipe flows into the inner cavity of the housing 100 from the inlet 140. The cooling water passes through a first filter screen 300, a second filter screen 400, and a third filter screen 500 in sequence, leaving impurities such as mud and sand on the filter screen assembly. Then, close the cooling water pipe, and use the drive device 200 to move the first filter screen 300, the second filter screen 400, and the third filter screen 500 upwards. Then, the drive unit 200 inserts another first filter screen 300, another second filter screen 400, and another third filter screen 500 into the corresponding groove assembly 160 to complete the filter screen assembly replacement operation; finally, the first valve 120 and the second valve 170 are opened, and the water sprayed by the spray assembly 130 is used to clean the above-mentioned recovered first filter screen 300, second filter screen 400, and third filter screen 500. The cleaned mud and impurities flow out through the discharge pipe to complete the filter screen assembly cleaning operation.

[0037] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
