Description

Technical Field

[0001] The utility model relates to the technical field of oil-slinging pans, in particular to an oil-slinging pan device. Background Art

[0002] A vacuum pump oil slinger is a device used to separate and recover the lubricating oil within the vacuum pump. During operation, the lubricating oil within the vacuum pump may be carried into the pump body by gases, which is where the oil slinger plays an important role. The lubricating oil in the vacuum pump contains impurities such as dust and metal particles. These impurities can reduce the oil's lubricating properties, increase friction and accelerate wear in the pump, and affect the pump's operational stability and performance.

[0003] Utility model patent publication number CN216477750U discloses an oil-slinging pan and vacuum pump. The pan comprises a pan body with oil reservoirs located on two opposing sides of the pan body. This reservoir increases the amount of oil in the pan, thereby improving the lubrication capacity of the device.

[0004] However, the prior art is unable to clean and filter the lubricating oil in the pump body. After the equipment has been in operation for a long time, wear and tear may cause metal debris and other impurities to be carried in the lubricating oil, thereby wearing out the components in the pump body. Utility Model Content

[0005] In response to the above technical problems, the present invention provides the following technical solutions: an oil-slinging pan device, comprising an oil-slinging pan and a transfer screw shaft arranged axially along the oil-slinging pan, the transfer screw shaft being provided with an installation key groove for installation and fixation, and a filter screen for filtering being provided on the outside of the transfer screw shaft.

[0006] Furthermore, a plurality of oil-spinning folds are distributed in an array on the oil-spinning plate, and an angle formed between the oil-spinning fold and the oil-spinning plate is less than 90°.

[0007] Furthermore, a plurality of oil guide plates are fixedly provided on one side of the oil-slinging pan, and a fixing ring is fixedly provided on the oil guide plates.

[0008] Furthermore, the filter screen is connected to the fixing ring via threads, and a plurality of through holes for filtering are provided on the filter screen.

[0009] Furthermore, a plurality of oil-spinning grooves are provided on the other side of the oil-spinning plate, and the oil-spinning grooves are arc-shaped.

[0010] Furthermore, the oil-spinning pan is provided with a plurality of oil filter holes, and the diameter of the oil filter holes is larger than the diameter of the through holes on the filter net.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. By arranging a filter screen and a transfer screw shaft capable of filtering the lubricating oil, the present invention can filter the lubricating oil during the operation of the oil-slinging pan, thereby preventing the lubricating oil from carrying metal debris and other impurities, which may cause wear to the components in the pump body; 2. By detachably mounting the filter screen on the oil-slinging pan, it is convenient to handle the metal debris inside the filter screen; 3. The function of the oil-slinging pan is increased, its applicability is increased, and its scope of application is wider. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 7The figure shows an oil-slinging pan device, comprising an oil-slinging pan 3 and a transfer screw shaft 4 arranged axially along the oil-slinging pan 3. The transfer screw shaft 4 is provided with a mounting keyway 5 for mounting and fixing, and a filter screen 6 is provided on the outer side of the transfer screw shaft 4 for filtering. The oil-slinging pan 3 is provided with a plurality of oil-slinging flanges 9 arranged in an array, and the angle formed between the oil-slinging flanges 9 and the oil-slinging pan 3 is less than 90 degrees. A plurality of oil guide plates 2 are fixedly mounted on one side of the oil-slinging pan 3, and a fixing ring 1 is fixedly mounted on the oil guide plates 2.

[0022] like Figures 1 to 7 As shown, the filter screen 6 is connected to the fixed ring 1 by threads, and a plurality of through holes for filtering are provided on the filter screen 6; a plurality of oil-slinging grooves 7 are provided on the other side of the oil-slinging plate 3, and the oil-slinging grooves 7 are arc-shaped; a plurality of oil filter holes 8 are provided on the oil-slinging plate 3, and the diameter of the oil filter hole 8 is larger than the diameter of the through hole on the filter screen 6.

[0023] like Figures 1 to 7 As shown, the utility model discloses an oil-slinging pan device, whose working principle is: the device is installed on the rotating shaft of the vacuum pump through the installation key slot 5, the vacuum pump is turned on, and the high-speed rotation of the vacuum pump drives the device to rotate at high speed. When the oil-slinging pan 3 rotates, oil droplets are thrown out from the mixture of oil and gas. The rotation of the oil-slinging pan 3 causes the oil to move outward under the action of centrifugal force, separating the oil droplets in the gas, and the oil droplets are thrown out through the oil-slinging groove 7 and the oil guide plate 2.

[0024] When the vacuum pump is running at a low speed, the transfer screw shaft 4 rotates, and the lubricating oil is transported to the filter screen 6 through the oil filter hole 8. The vacuum pump is then accelerated to throw out the lubricating oil droplets in the filter screen 6. At this time, the lubricating oil droplets are filtered by the filter holes on the filter screen 6, and the metal debris left after the equipment is worn is retained in the filter screen 6, preventing the metal debris from entering the lubricating oil and causing damage to the vacuum pump.

[0025] After the device has been running for a period of time, the operator manually rotates the filter screen 6, removes the filter screen 6 from the fixing ring 1, cleans the impurities in the filter screen 6, and installs it to the initial state again after cleaning for recycling.
