Detailed Implementation
[0020] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0021] like Figure 1 , Figure 2 As shown, this utility model discloses an automatic liquid level control device for waxing aluminum bolts, comprising a liquid containment tank consisting of a storage tank 1, a buffer tank 2, and a stabilizing tank 3. A filter screen 4 is installed at the output end of the storage tank 1. The output end of the storage tank 1 is connected to a first pipe 5 and a second pipe 6. The output ends of the first pipe 5 and the second pipe 6 are connected to an A three-way regulating valve 7. The output end of the A three-way regulating valve 7 is connected to a water pump 8. The output end of the water pump 8 is connected to a B three-way regulating valve 9. The B three-way regulating valve 9 has one output... One end is connected to a drain pipe 10, and the other output end of the B three-way regulating valve 9 is connected to a delivery pipe 11. The output end of the delivery pipe 11 is placed on top of the buffer tank 2. The buffer tank 2 is equipped with a return pipe 12, and the output end of the return pipe 12 is placed in the storage tank 1. The buffer tank 2 is connected to the stabilizing tank 3. The bottom surfaces of the buffer tank 2 and the stabilizing tank 3 are at the same level. A partition 17 is provided between the buffer tank 2 and the stabilizing tank 3. A filter 13 is placed in the stabilizing tank 3. The lowest level of the filter 13 is lower than the level of the input end of the return pipe 12.
[0022] In the embodiment, when the automatic control liquid level device for waxing aluminum bolt is used, the A three-way regulating valve 7 is adjusted to open the first pipeline 5 and close the second pipeline 6, the B three-way regulating valve 9 is adjusted to open the liquid feeding pipeline 11 and close the liquid discharging pipeline 10, and then the water pump 8 is started. Under the effect of suction, the wax liquid flows from the liquid storage pool 1 to the water pump 8 through the first pipeline 5 and the A three-way regulating valve 7. During the process, the filter screen 4 is arranged to filter the wax liquid. Under the effect of the water pump 8, the wax liquid flows into the buffer pool 2 from the liquid feeding pipeline 11. Under the effect of the partition plate 17, the power of the flowing wax liquid is eliminated, and the wax liquid flows into the stable liquid pool 3 from the lower side of the partition plate 17. At this time, the power of the wax liquid is not large, so that the stability of the liquid level of the stable liquid pool 3 is ensured, and the fluctuating liquid level does not affect the waxing and lubrication of the specified area of the aluminum bolt, and the quality consistency of the waxing product is ensured. When the liquid level height of the buffer pool 1 reaches the height of the input end of the liquid return pipeline 12, the wax liquid flows back into the liquid storage pool 1 through the liquid return pipeline 12, so as to prevent overflow of the buffer pool 2 and realize circulation of the wax liquid. The flowing wax liquid will not solidify, and the use effect is ensured.
[0023] Then the automatic equipment grasps the aluminum bolt, and then moves to the stable liquid pool position under the driving of the program, and then immerses the specified area of the aluminum bolt into the wax liquid, that is, the waxing work of the aluminum bolt is completed.
[0024] The height of the liquid level is controlled by the horizontal height of the input end of the liquid return pipeline 12. The moving position of the automatic equipment for grasping the aluminum bolt can also be controlled to realize the waxing effect of the braking area of the aluminum bolt. This point is easy to understand for those skilled in the art.
[0025] After the waxing work is completed, in order to save resources and prevent the solidification of the wax liquid due to the stop of the water pump 8, the wax liquid can be completely discharged from the liquid discharging pipeline 10 for recycling. The operation mode is that the B three-way regulating valve 9 is controlled to open the liquid discharging pipeline 10 and close the liquid feeding pipeline 11, and the water pump 8 is started. Then the wax liquid is discharged from the liquid discharging pipeline 10 for collection. Further, the A three-way regulating valve 7 is controlled to open the first pipeline 5 and the second pipeline 6, so as to accelerate the discharge of the wax liquid.
[0026] Preferably, the horizontal height of the liquid storage pool 1 is lower than that of the buffer pool 2. Such design is beneficial to the flow of the wax liquid from the input end of the liquid return pipeline 12 under the self-weight. In fact, the horizontal height of the liquid storage pool 1 can also be considered according to the specific situation.
[0027] Preferably, the slide 14 is oppositely arranged on the side wall of the liquid storage pool 1, and the filter screen 4 is plug-in installed on the slide 14. Such design is beneficial to the removal of the filter screen 4 for cleaning and replacement. In fact, the installation mode of the filter screen 4 can also be considered according to the specific situation.
[0028] Preferably, the stable liquid pool 3 is installed with a drying plate 15, which can be used to place the falling parts or unqualified parts, and also can be used as a comparison platform, and in fact, the size of the drying plate 15 can be considered according to the specific situation.
[0029] Preferably, the stable liquid pool 3 is installed with a liquid level meter 16, which is signal connected to a background control terminal, and such a design can be used as an insurance for the liquid level height, and when the height changes greatly, the background control can be stopped, and in fact, the insurance measures can be considered according to the specific situation.
