Description

Technical Field

[0001] The utility model relates to the technical field related to water tank structures, in particular to a flow diversion structure in a water tank. Background Art

[0002] In grinding, with the improvement of machining accuracy, high-speed grinding and strong grinding technologies are developing rapidly. In addition to selecting reasonable grinding parameters, the circulation quality of cutting fluid must also be improved. Cutting fluid often contains a large amount of magnetic impurities, so a purification device is required to remove these magnetic impurities. Magnetic separator is one of the purification devices used to purify cutting fluid. Existing magnetic separators usually include a shell, a magnetic roller and a pressure roller arranged on the shell, a motor arranged on the outside of the magnetic roller and driving the magnetic roller to rotate, and a scraper in contact with the magnetic roller. After the cutting fluid containing magnetic impurities enters the shell, as the magnetic roller continues to rotate, the magnetic impurities are adsorbed on the outer wall of the magnetic roller, and then the liquid entrained in the magnetic impurities is squeezed out by the pressure roller. Finally, the scraper separates the magnetic impurities from the magnetic roller, thereby achieving the purification of the cutting fluid.

[0003] Generally, a magnetic separator (abbreviated as magnetic separator) is a single-stage structure with only one magnetic roller. When the flow rate is huge and the size of the equipment is limited, a double-stage structure, i.e., two magnetic rollers, is generally used. The existing water tank loaded with magnetic rollers does not have a shunt structure inside, resulting in uneven separation capabilities of the two magnetic rollers, affecting the use effect. For this reason, those skilled in the art have proposed a shunt structure inside the water tank to solve the problems raised in the above background. Utility Model Content

[0004] The purpose of the utility model is to provide a flow diversion structure in a water tank to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The top of the outer plate is connected to the inner top surface of the water tank, and a distance is left between the bottom end of the outer plate and the inner bottom surface of the water tank. The top of the outer plate is connected to the inner top surface of the water tank, and a distance is left between the bottom end of the outer plate and the inner bottom surface of the water tank. The outer plate is arranged between the inner plate and the upper magnetic roller, and a diversion port is formed in the area between the inner plate and the outer plate, and a plurality of partitions are arranged at equal intervals in the diversion port, and a flat plate is connected to the bottom outer wall of the outer plate on the side close to the upper magnetic roller, and the diversion port is used to divide the incoming dirty liquid into equal parts, half of the equally divided dirty liquid flows along the inner bottom surface of the water tank to the lower magnetic roller, and the other half of the dirty liquid flows along the flat plate to the upper magnetic roller.

[0007] As a further solution of the utility model: a plurality of rows of openings are arranged at equal intervals on the bottom end of the outer plate, and the sum of the lengths of the plurality of rows of openings is one half of the length of the outer plate.

[0008] As a further solution of the utility model: the bottoms of the two partitions corresponding to the position of the discharge port are commonly connected with a sealing plate, the length of the sealing plate is consistent with the length of the discharge port, and the setting position of the sealing plate corresponds to the bottom end position of the discharge port.

[0009] As a further solution of the utility model: the setting height of the inner plate is half of the setting height of the water tank.

[0010] As a further solution of the utility model: the upper magnetic roller and the lower magnetic roller are arranged at positions staggered with each other in both the horizontal direction and the vertical direction.

[0011] The utility model has the following advantages: the structure forms a diversion port inside the water tank by cooperating with the inner plate and the outer plate, and utilizes the characteristic of the liquid surface growing evenly so that the partition in the diversion port can divide the inflowing dirty liquid into equal parts, and the equally divided dirty liquid flows to the lower magnetic roller and the upper magnetic roller respectively for purification treatment, thereby ensuring the uniformity of use of the upper magnetic roller and the lower magnetic roller and improving the treatment effect of the dirty liquid.

[0017] The technical solution of the utility model is further described in detail below in conjunction with specific implementation methods.

[0018] Example 1: Please refer to Figures 1 to 4A water tank internal flow diversion structure comprises a water tank 1, wherein one side of the inner cavity of the water tank 1 is provided with an upper magnetic roller 7 and a lower magnetic roller 6 distributed up and down, and the inner cavities on both sides of the water tank 1 are provided with an inner plate 2 and an outer plate 3, the bottom end of the inner plate 2 is connected to the inner bottom surface of the water tank 1, and a distance is left between the top end of the inner plate 2 and the inner top surface of the water tank 1, the top end of the outer plate 3 is connected to the inner top surface of the water tank 1, and a distance is left between the bottom end of the outer plate 3 and the inner bottom surface of the water tank 1, the outer plate 3 is arranged between the inner plate 2 and the upper magnetic roller 7, and a diversion port 8 is formed in the area between the inner plate 2 and the outer plate 3, that is, the inner plate 2 and the outer plate 3 are connected to each other. The overlapping part of the plate 3 in the horizontal direction is set as a diversion port 8, and a plurality of partitions 4 are arranged at equal intervals in the diversion port 8. The setting height of the partition 4 is consistent with the setting height of the diversion port 8. The bottom outer wall of the outer plate 3 on the side close to the upper magnetic roller 7 is connected with a flat plate 5. The diversion port 8 is used to divide the incoming dirty liquid into equal parts, and half of the equally divided dirty liquid flows along the inner bottom surface of the water tank 1 to the lower magnetic roller 6, and the other half of the dirty liquid flows along the flat plate 5 to the upper magnetic roller 7. The upper magnetic roller 7 and the lower magnetic roller 6 are both connected to the driving structure installed on the outer wall of the water tank 1, and the driving mechanism can be selected from the device used to drive the magnetic roller to operate in the prior art.

[0019] See also Figures 1 to 4 A plurality of discharge ports 9 are evenly spaced at the bottom end of the outer plate 3, and the sum of the lengths of the plurality of discharge ports 9 is half of the length of the outer plate 3. In this embodiment, the bottoms of the two partitions 4 corresponding to the positions of the discharge ports 9 are commonly connected with a sealing plate 10, and the length of the sealing plate 10 is consistent with the length of the discharge port 9. The setting position of the sealing plate 10 corresponds to the bottom end position of the discharge port 9. After the dirty liquid flows into the diversion port 8, part of the dirty liquid is blocked by the sealing plate 10 and cannot flow downward. The blocked dirty liquid can only be discharged onto the flat plate 5 through the discharge port 9, and finally flows to the upper magnetic roller 7.

[0020] Example 2: See Figure 1 On the basis of the first embodiment, the setting height of the inner plate 2 is half of the setting height of the water tank 1, so that the water tank 1 has a certain accumulation effect and does not affect the influx of dirty liquid from the diversion port 8.

[0021] See also Figure 1 The upper magnetic roller 7 and the lower magnetic roller 6 are arranged at positions that are staggered with each other in the horizontal direction and the vertical direction. This structure makes full use of the internal space of the water tank 1 and reduces the working interference between the upper magnetic roller 7 and the lower magnetic roller 6.

[0022] Working principle: When in use, dirty liquid enters from the top opening of the water tank 1, and accumulates between the inner wall of the water tank 1 and the inner plate 2. When the dirty liquid level reaches the top of the diversion port 8, the dirty liquid flows into the diversion port 8, and is equally divided by the partition 4 in the diversion port 8. Part of the dirty liquid flows downward to the inner bottom surface of the water tank 1, and finally flows to the lower magnetic roller 6. The other part of the dirty liquid is blocked by the sealing plate 10 and cannot flow downward, and is discharged to the flat plate 5 through the discharge port 9, and finally flows to the upper magnetic roller 7.
