DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0023] Please refer to the drawings Figures 1-4 A cooling water purifying device comprises:

[0024] The box body 1 is provided with a water inlet pipe 10 at the upper end and a water outlet pipe 11 at the lower end, the water outlet pipe 11 is provided with a water pump 110 at the end away from the box body 1, and the box body 1 is provided with a taking and placing opening 12 on the top surface, the water flow guiding assembly 2 comprises an annular upper plate 20, a cylindrical shell 21 and an annular lower plate 22, the cylindrical shell 21 is fixedly connected with the annular upper plate 20 and the annular lower plate 22 at both ends respectively, and the inner wall of the cylindrical shell 21 is provided with an annular middle plate 210 fixedly connected therewith, the annular lower plate 22 is connected with the water outlet pipe 11 through a connecting pipe 220, and the filtering assembly 3 is movably connected in the cylindrical shell 21.

[0025] Specifically, the top surface of the annular upper plate 20 is provided with a plurality of arc-shaped notches 200.

[0026] The water flow guiding assembly 2 arranged in the box body 1 guides the flow direction of the cooling water, so that the cooling water flows into the cylindrical shell 21 from the arc-shaped notches 200 arranged on the annular upper plate 20, and is discharged to the water outlet pipe 11 through the annular lower plate and the connecting pipe 220, and then enters the cooling circulation system again through the water pump 110. In this process, the white flocculent floating matter on the water surface will flow to the annular upper plate 20, part of which will enter the cylindrical shell 21 under the impact of the water flow and be filtered by the filtering assembly 3.

[0027] Specifically, the top surface of the annular upper plate 20 is provided with an annular buoyancy block 201 fixedly connected therewith, and the buoyancy of the annular buoyancy block 201 is greater than the weight of the water flow guiding assembly 2 and the filtering assembly 3. Considering that the water level in the box body 1 is not always at the same height, in order to avoid the change of the water level being too large to cause the cooling water to be unable to enter the water flow guiding assembly 2, the annular buoyancy block 201 is arranged on the annular upper plate 20, so that the position of the water flow guiding assembly 2 can change according to the water level. It should be noted that the connecting pipe 200 needs to be made of soft material (such as a hose) to adapt to the position change of the water flow guiding assembly 2.

[0028] Specifically, the filtering assembly 3 comprises a cylindrical filter screen 30 and an annular plate 31, the annular plate 31 is placed on the annular middle plate 210, and the cylindrical filter screen 30 is fixedly connected to the bottom surface of the annular plate 31.

[0029] Specifically, the outer diameter of the annular plate 31 is greater than the inner diameter of the annular middle plate 210, and the inner diameter of the annular plate 31 is smaller than the inner diameter of the annular middle plate 210;

[0030] In order to filter the white flocculent floating matter entering the cylindrical shell 21, the filter assembly 3 is arranged, and the filter assembly 3 and the water flow guiding assembly 2 are separated in the mode that the filter assembly 3 is composed of the filter screen 30 and the annular plate 31, so that when the filter assembly 3 needs to be cleaned, the filter assembly 3 can be taken out. In order to facilitate the taking out of the filter assembly 3, a pulling rope for extracting the filter assembly 3 can be bound on the annular plate 31 in advance, and the pulling rope is located outside the taking and placing opening 12 at one end away from the annular plate 31. When the filter assembly 3 is taken out, the taking and placing opening 12 is opened, and the filter assembly 3 is pulled out directly. At the same time, in actual application, if the floating matter to be filtered is very small, the filter screen 30 can be directly fixedly connected to the inner wall of the cylindrical shell 21 to complete the filtering, and the water flow guiding assembly 2 and the filter screen can be taken out for cleaning.

[0031] Specifically, the water flow guiding assembly 2 is provided with a position adjusting assembly 4 matched therewith, the position adjusting assembly 4 comprises a winding disc 40, a winding handle 41, a winding shaft 42 and a traction rope 43, one end of the winding shaft 42 is connected to the side wall of the box body 1 through a bearing after penetrating through the winding disc 40, the other end is fixedly connected with the winding handle 41, and the winding shaft 42 is fixedly connected with the winding disc 40, the traction rope 43 is wound on the winding disc 40, and the two ends of the traction rope 43 are respectively connected with the water flow guiding assembly 2 after penetrating through the two side walls of the box body 1 opposite in position;

[0032] Specifically, the traction rope 43 is wound at least one turn on the winding disc 40;

[0033] Considering that the position of the water flow guiding assembly 2 needs to be adjusted in some cases, but the existing adjustment method is usually through the taking and placing opening 12, which is very inconvenient, therefore, the position adjusting assembly 4 is arranged, when the position of the water flow guiding assembly 2 needs to be adjusted, the winding handle 41 is rotated, the winding disc 40 is driven to rotate through the winding shaft 42, at this time, the traction rope 43 wound on the winding disc 40 will appear one end winding and one end unwinding, the water flow guiding assembly 2 will move towards the winding end of the traction rope 43, it should be noted that, since the position requirement of the water flow guiding assembly 2 is not strict, and the water flow speed in the box body 1 is not fast, usually the position of the water flow guiding assembly 2 will not be greatly deviated after being adjusted, therefore, the winding handle 41 is not locked, when the position of the water flow guiding assembly 2 is found to be unsuitable during the daily inspection of the staff, it can be quickly adjusted, if it needs to be locked, it can also be quickly completed through other ways, for example, the adjusted winding handle 41 and the external frame body can be bound through a binding belt, at the same time, considering that the water flow guiding assembly 2 will appear up and down floating with the liquid level of the cooling water, therefore, under normal circumstances, the traction rope 43 is in a relaxed state, at the same time, the direction of the traction rope 43 can be determined according to the actual situation, for example, the traction rope 43 is guided by the guide wheel 45 in the drawing. Figure 1 The guide wheel is adopted for guidance for the purpose of beauty.

[0034] Considering that part of the traction rope 43 passes over the edge of the box body 1, if it is not protected, the traction rope 43 may be seriously worn, specifically, the arc-shaped corner piece 13 is arranged on the edge of the box body 1 and is fixedly connected with the box body 1, and the arc-shaped corner piece 12 is in contact with the traction rope 43, the arc-shaped corner piece 13 is not only the protection of the box body 1 itself, but also the protection of the traction rope 43.

[0035] Specifically, the transparent observation window 14 matched with the position of the winding disc 40 is arranged on the box body 1, in order to facilitate the use of the position adjusting assembly 4, the corresponding transparent observation window 14 is arranged for observation, if the box body 1 adopts a smaller specification, the position adjusting assembly 4 and the transparent observation window 14 can also be arranged on the top surface of the box body 1.

[0036] The above is only the preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the technical field according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model makes equivalent replacement or change, which should be covered in the protection scope of the utility model.
