Description

Technical Field

[0001] The utility model relates to the field of graphite water tanks, in particular to a graphite water tank for preventing graphite precipitation. Background Art

[0002] Graphite has a crystal structure with a hexagonal crystal system. Because the intermolecular force between the planes parallel to the basal plane is weak, these crystals are easily sheared between their planes, that is, the frictional force is small. At the same time, they can support the load perpendicular to the basal plane, so they have strong load-bearing capacity, small friction coefficient, and the best properties as lubricants. The suspension of graphite dispersed in water, oil or solvent is commonly used as a lubricating release agent for hot plastic processing of metals. For example, the mold cavity often uses graphite water to achieve lubrication. The graphite water in the graphite water tank is pumped by a pump body to spray the lubrication part. However, the graphite concentration error at different positions in the existing graphite water tank reaches between 20% and 30%, and the uniformity of the graphite water mixture is poor, resulting in uneven adsorption of graphite powder on the mold cavity, affecting mold lubrication and cooling. In addition, a large amount of precipitated graphite at the bottom of the graphite water tank will also cause blockage of the suction pump body and reduce its service life.

[0024] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Such as Figure 1Shown is a specific implementation manner of the graphite water tank provided by the present utility model. The graphite water tank includes a water tank body 10 for accommodating a graphite water mixture. At least one partition 11 is provided in the water tank body 10 to divide the water tank body 10 into at least two stirring chambers 10a; each of the stirring chambers 10a includes a power stirring device 20 and a flow disturbing device 30; wherein, the flow disturbing device 30 is arranged closer to the partition 11 than the power stirring device 20. The power stirring device 20 includes a first stirring impeller 21 and a stirring motor 22 for driving the first stirring impeller 21 to rotate; the flow disturbing device 30 includes a flow disturbing pipe 31 and a plurality of flow disturbing holes 31a provided on the wall of the flow disturbing pipe 31, and the flow disturbing pipe 31 is connected to a high-pressure air supply device to realize high-pressure air jetting.

[0026] In the above-mentioned graphite water tank, multiple stirring chambers 10a are divided by the partition 11 to realize regional stirring and flow disturbance; wherein, the first stirring impeller 21 faces the bottom of the water tank body 10 to stir the water body located below the first stirring impeller 21; the stirred water body changes its flow direction after flowing to the bottom wall of the water tank body 10 and forms a flow trend parallel to the bottom wall of the water tank until it encounters the partition 11 or the side wall of the water tank body 10 again, and continues to form a disturbance flow; the flow disturbing device 30 jets air into the water tank body 10 through the flow disturbing pipe 31 connected to the high-pressure air supply device to disturb the graphite water; through the above stirring and disturbing structures, the problem of uneven mixing of the graphite water in the graphite water tank can be avoided.

[0027] Specifically, in an optional implementation manner, the water tank body 10 is a square tank body, and the power stirring device 20 is arranged in the area of the tank wall opposite to the partition 11, which can make the water body in the area of the tank wall farthest from the partition 11 have the strongest disturbance, and it is gradually transmitted along the bottom wall to the area where the partition 11 is located, while the flow disturbing device 30 is arranged in the area close to one side of the partition 11. For example, the distance L1 between the flow disturbing device 30 and the partition 11 is about one-third of the distance L0 between the tank wall opposite to the partition 11 and the partition 11. It can realize flow disturbance in the area that cannot be covered by the power stirring device 20, and avoid the formation of dead zones in some areas of the water tank body 10, resulting in graphite deposition.

[0028] Specifically, in an optional implementation manner, the flow disturbing pipe 31 includes a main pipe body 311 and an annular branch pipe 312 connected to the end of the main pipe body 311, and a plurality of the flow disturbing holes 31a are opened along the circumferential direction of the annular branch pipe 312. By providing the annular branch pipe 312, the coverage area of the flow disturbing pipe 31 can be increased to obtain a better flow disturbance effect.

[0029] Specifically, in order to further improve the flow disturbance effect of the flow disturbance device, in an optional implementation manner, a plurality of the flow disturbance tubes 31 are arranged at intervals in the width direction and / or the length direction of the stirring chamber 10a.

[0030] Specifically, in an optional implementation manner, in order to further improve the uniformity of the graphite water, as Figure 3 shown, the graphite water tank further includes a non-powered stirring device 40, which is arranged at a position close to the flow disturbance holes 31a of the flow disturbance tubes 31, and includes a second stirring impeller 41, and the second stirring impeller 41 rotates under the action of the high-pressure gas flowing out of the flow disturbance holes 31a. By arranging the non-powered stirring device 40, the high-pressure gas discharged by the flow disturbance device 30 can be used as power to rotate the second stirring impeller 41, further disturbing the water body around it and preventing the graphite from depositing downward.

[0031] Specifically, in an optional implementation manner, as Figure 2 shown, the partition plate 11 is provided with a plurality of communication holes 11a from bottom to top, so that a plurality of stirring chambers 10a are in a mutually connected state, and the opening sizes of the communication holes 11a gradually increase from bottom to top, so that the degree of mutual disturbance of the water body in the upper region is higher than that of the water body in the lower region.

[0032] Under the action of the power stirring device 20, the water body in the area of the partition plate 11 usually flows in the vertical direction and forms a horizontal flow disturbance at the position of the communication holes 11a. In order to further increase the vertical flow disturbance effect, a plurality of fins 111 are provided on both sides of the partition plate 11 from bottom to top, and a plurality of through holes are provided on the fins 111.

[0033] More specifically, as Figure 2 shown, the partition plate 11 is provided with a row of rectangular communication holes 11a from bottom to top, the fins 111 are located in the lower region of the communication holes 11a, and adjacent fins 111 are respectively located on opposite sides of the partition plate 11. The adjacent fins 111 are arranged in parallel and staggered, which can make there be a pressure difference between the water bodies on both sides of the communication holes 11a, so that the water body in this area flows more smoothly, and the flow directions of the water bodies on both sides of the partition plate 11 between different layers are opposite, further making the water bodies between different layers form a turbulent flow, improving the fluidity of the water body in the area of the partition plate 11, and further preventing graphite precipitation.

[0034] Specifically, in an optional implementation manner, as Figure 3As shown, the non-powered stirring device 40 includes a support shaft 42 fixed to the bottom wall of the water tank body 10 and at least one second stirring impeller 41 rotatably connected to the support shaft 42. The second stirring impeller 41 is at the same horizontal position as the flow disturbance holes of the flow disturbance pipe. The high-pressure gas ejected through the flow disturbance holes acts on the surrounding graphite liquid and also acts on the second stirring impeller 41, causing the second stirring impeller 41 to rotate around its support shaft 42, further agitating the surrounding liquid to avoid graphite deposition.

[0035] More specifically, a number of through holes are provided on the second stirring impeller 41, which can make the surrounding liquid form a turbulent flow, further avoiding graphite deposition.

[0036] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. The obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
