Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for chip conveyors, and more specifically, it relates to a deaerator for the water tank of a chip conveyor. Background Technology

[0002] Currently, in machining processes (such as milling, drilling, and grinding), chip conveyors continuously transport metal chips (mainly iron chips) generated by the workpiece from the machining area to a water tank. The cutting fluid stored in the tank is then returned to the machining area through a circulation system to achieve cooling, lubrication, and rust prevention functions. However, the cutting fluid is prone to generating a large amount of foam during circulation due to the following reasons:

[0003] Mechanical stirring effect: The rotation of the chip conveyor belt and the high-speed operation of the cutting fluid circulation pump will draw air into the cutting fluid, forming dispersed foam;

[0004] Chemical reaction effects: Emulsifiers, rust inhibitors and other additives in cutting fluids are prone to decomposition under high-temperature processing conditions, which can disrupt the surface tension of the liquid and lead to continuous foam generation.

[0005] Iron filings carrying air: Iron filings (especially rolled or clump-shaped iron filings) conveyed by the chip conveyor are prone to carrying air into the water tank, which further aggravates foam generation.

[0006] The existing defoaming solutions for chip conveyor water tanks have the following main drawbacks:

[0007] Low defoaming efficiency and easy clogging: Some centrifugal defoamers use a straight blade structure, which has no ability to break up clumps of iron filings. The iron filings are easy to get tangled in the blades or stuck in the gap between the blades and the shell, which leads to a decrease in defoaming speed and even motor overload.

[0008] Low level of automation: Existing equipment mostly requires manual observation of foam volume and manual start-stop, and cannot respond to changes in foam thickness in real time; when the processing load changes suddenly, the foam volume increases sharply during high-speed cutting, and manual control can easily cause foam to overflow from the water tank, polluting the workshop environment.

[0009] In addition, existing iron filings collection devices need to be installed separately at the bottom or side of the water tank, and are not designed in conjunction with the defoamer. This not only occupies water tank space, but also requires additional manual cleaning periodically, increasing the workload of operators. Utility Model Content

[0010] To address the shortcomings of existing technologies, this utility model provides a deaerator for the water tank of a chip conveyor, thereby solving the problems mentioned in the background section.

[0011] To achieve the above objectives, this utility model provides the following technical solution: a defoamer for a chip conveyor water tank, comprising a cover plate for installation on the chip conveyor water tank. The cover plate has a central mounting hole, and a treatment hood is welded to the top of the mounting hole. A motor is mounted on the top of the treatment hood, and the motor's drive end is connected to a rotating defoaming component. The rotating defoaming component is located inside the treatment hood, and its bottom is lower than the bottom surface of the cover plate. A detection frame is mounted on one corner of the cover plate, and the detection frame is equipped with a foam detection component for detecting foam thickness.

[0012] As an optional solution of this utility model, the rotating defoaming component includes multiple centrifugal blades, which are arc-shaped and have symmetrical positioning discs welded to the top and bottom. The blades quickly break up the iron filings into clumps through the saw teeth. An adapter is welded to the top of the upper positioning disc, and a chip collection port is provided on the bottom positioning disc. A chip collection mechanism is welded to the bottom of the chip collection port.

[0013] As an optional solution of this utility model, the multiple centrifugal blades are arranged in a circumferential array, and each of the multiple centrifugal blades has a row of serrations at its end.

[0014] As an optional solution of this utility model, the chip collection mechanism includes a guide cover welded to the bottom of the chip collection port, and a filter basket is installed at the bottom of the guide cover by a pin. The filter basket is made of stainless steel.

[0015] As an optional embodiment of this invention, the top of the processing cover is also welded with symmetrical handles.

[0016] As an optional solution of this utility model, the foam detection assembly includes a proximity switch installed on the top of the detection frame, the proximity switch being electrically connected to a motor, a detection float rod being provided below the proximity switch, a foam float plate being provided at the bottom of the detection float rod, the detection float rod being slidably fitted to the bottom of the detection frame, a limit plate being provided on the detection float rod for limiting, and a top plate being provided at the top of the detection float rod.

[0017] This utility model provides a defoamer for the water tank of a chip conveyor, which has the following beneficial effects:

[0018] By combining centrifugal blades for defoaming, serrated ends for crushing iron filings, and a filter basket for collection, the problem of foam and iron filings is solved simultaneously. While defoaming, iron filings can also be collected to prevent them from clogging the defoaming components. The filter basket is detachable, so it can be easily removed for cleaning.

[0019] By designing a foam float that can float on the foam, the foam thickness in the water tank can be continuously monitored. Once a certain thickness is reached, the motor is automatically controlled to perform automatic defoaming without the need for manual observation. Attached Figure Description

[0028] Please see Figures 1 to 4This utility model provides a technical solution: a defoamer for a chip conveyor water tank, including a cover plate 1 for installation on the chip conveyor water tank. The cover plate 1 has a mounting hole in the center, and a treatment cover 101 is welded to the top of the mounting hole. A motor 3 is installed on the top of the treatment cover 101. The drive end of the motor 3 is connected to a rotating defoaming component. The rotating defoaming component is located inside the treatment cover 101, and its bottom is lower than the bottom surface of the cover plate 1. The rotating defoaming component includes multiple centrifugal blades 9, which are arc-shaped and have symmetrical positioning discs 10 welded to the top and bottom. The multiple centrifugal blades 9 are arranged in a circumferential array. Each centrifugal blade 9 has a row of serrations 901 at its end. The serrations 901 quickly break up the clumps of iron filings and collect them quickly. An adapter 301 is welded to the top of the upper positioning disc 10 for easy connection to the drive end of the motor 3. The lower positioning disc 10 has a chip collection port, and a chip collection mechanism is welded to the bottom of the chip collection port. The chip collection mechanism collects the iron filings and impurities that centrifugally rotate into the center of the positioning disc 10.

[0029] The chip collection mechanism includes a guide cover 7 welded to the bottom of the chip collection port. A filter basket 8 is installed at the bottom of the guide cover 7 by means of pins. The filter basket 8 is made of stainless steel and can filter cutting fluid while collecting iron filings. Symmetrical handles 2 are also welded to the top of the treatment cover 101 to facilitate overall installation. A detection frame 4 is installed at one corner of the cover plate 1. The detection frame 4 is equipped with a foam detection component to detect the foam thickness and quickly defoam when a certain thickness is reached.

[0030] The foam detection assembly includes a proximity switch 5 installed on the top of the detection frame 4, which is electrically connected to the motor 3. A detection float 6 is located below the proximity switch 5, and a foam float plate 603 made of plastic foam is located at the bottom of the detection float 6 so that it can float on the foam. The detection float 6 is slidably fitted to the bottom of the detection frame 4. A limit plate 601 is provided on the detection float 6 to limit it and prevent it from falling into the chip conveyor water tank. A top plate 602 is provided on the top of the detection float 6. When the top plate 602 contacts the proximity switch 5, the motor 3 is immediately started to perform defoaming operation, automatically defoaming the foam.

[0031] The specific usage and function of this embodiment: The cover plate 1 is installed on the water tank by the handle 2. After it is fixed, the motor 3 is started for rotation test. If everything is normal, the motor 3 is stopped. The cutting fluid and iron filings discharged by the chip conveyor begin to enter the water tank. Foam begins to form on the surface. The foam floats on the foam through the foam float plate 603. After reaching a certain thickness, the top plate 602 of the top of the detection float 6 contacts the proximity switch 5. The proximity switch 5 sends a signal to start the motor 3. The motor 3 starts immediately, driving the positioning plate 10 and the central centrifugal blade 9 to rotate. The serrations 901 at the end of the centrifugal blade 9 break up the clumps of iron filings, which are quickly sucked into the center and enter the guide hood 7 through the chip collection port. The filter basket below the guide hood 7 collects and filters the cutting fluid without affecting the flow of cutting fluid until the foam is eliminated. The machine is then stopped. The filter basket 8 is removed periodically for centralized chip removal. The operation is simple and does not require personnel to observe.
