Description

Technical Field

[0001] This utility model relates to the field of lubricating oil production technology, specifically to a defoamer feeding device for lubricating oil production. Background Technology

[0002] Lubricating oil products are made by blending base oils with various additives. Base oil is the main component of lubricating oil, determining its basic properties. Additives improve its physicochemical properties, imparting new special properties or enhancing existing properties to meet higher requirements. The correct selection and reasonable addition of additives are crucial to the quality and performance of lubricating oil. During lubricating oil blending, foam is often generated due to stirring. If this foam is not dealt with promptly, it will affect the quality of the finished oil and its later performance. Therefore, it is necessary to add an appropriate amount of defoamer.

[0003] Application number CN201921431130.5 discloses a defoamer feeding device for lubricating oil production. Through the feeding mechanism, when defoamer needs to be added during lubricant production, the operator can control a servo motor to rotate, driving the first and second gears to mesh and rotate. This, in conjunction with a thrust bearing and a lead screw, causes a connecting ring to descend along the outer wall of the lead screw. The connecting ring then lowers the fixed seat and the feeding bottle. During descent, the compressible feeding bottle is squeezed out by the feeding chamber and the fixed seat, and the defoamer enters the buffer chamber. The defoamer is then injected into the tank through a connecting pipe. The amount of defoamer added can be controlled by the ratio of the effective motor rotation speed to the amount of material discharged from the feeding bottle. A sliding rod helps maintain the balance between the fixed seat and the feeding bottle, preventing the bottle from tilting during compression and affecting the feeding measurement.

[0004] The defoamer feeding device for lubricant production disclosed in the aforementioned patent requires periodically filling the compressible bottle with material when the material inside is emptied. Manual addition wastes manpower, while pumping in with a separate pump increases costs and wastes electricity. Utility Model Content

[0005] The purpose of this utility model is to provide a defoamer feeding device for lubricating oil production. After the defoamer is quantitatively added into the reaction tank through the feeding cylinder, the defoamer is automatically added into the feeding cylinder from the storage tank by lifting the sealing pressure plate upwards. This eliminates the need for frequent feeding, saves manpower, and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a defoamer feeding device for lubricating oil production, comprising a reaction tank, a feeding cylinder and an electric telescopic rod mounted on the outer wall of the reaction tank via a support frame, a quantitative extrusion assembly being slidably installed inside the feeding cylinder, the bottom inlet of the feeding cylinder being connected to the outlet of a storage tank via a feeding pipe and a one-way feeding valve, and the bottom outlet of the feeding cylinder being connected to the upper feeding port of the reaction tank via a discharge pipe and a one-way discharge valve.

[0007] Preferably, the top feeding port of the storage tank is detachably fitted with a sealing cap, and the storage tank contains defoamer.

[0008] Preferably, the quantitative extrusion assembly includes a sealing pressure plate that is slidably connected to the inner wall of the feeding cylinder, and a sliding column is fixedly installed on the top of the sealing pressure plate. The sliding column is slidably connected to the top sliding hole of the feeding cylinder.

[0009] Preferably, a top bar is fixedly installed on the top of the sliding column, and an electric telescopic rod is installed at the bottom of the other end of the top bar.

[0010] Preferably, an infrared ranging sensor receiver is embedded in the top of the feeding cylinder, and an infrared ranging sensor transmitter is embedded in the corresponding position at the bottom of the top bar.

[0011] Preferably, both the sliding column and the sealing pressure plate are made of stainless steel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The defoamer feeding device for lubricating oil production disclosed in this utility model automatically adds defoamer from the storage tank into the feeding cylinder by pulling up the sealing pressure plate after quantitatively adding defoamer into the feeding cylinder through the feeding cylinder through the feeding cylinder. This eliminates the need for frequent feeding, saving manpower and solving the problem of the defoamer feeding device for lubricating oil production disclosed in the above-mentioned patent, which requires periodically filling the compressible material bottle when the material is squeezed out.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-3 The diagram shows a defoamer feeding device for lubricating oil production, including a reaction tank 1. A feeding cylinder 12 and an electric telescopic rod 7 are installed on the outer wall of the reaction tank 1 via a support frame 6. A quantitative extrusion assembly is installed in a sealed sliding manner inside the feeding cylinder 12. The bottom inlet of the feeding cylinder 12 is connected to the outlet of the storage tank 2 via a feeding pipe 4 and a one-way feeding valve 13. The bottom outlet of the feeding cylinder 12 is connected to the upper feeding port of the reaction tank 1 via a discharge pipe 5 and a one-way discharge valve 14. After the defoamer is quantitatively added into the reaction tank 1 through the feeding cylinder 12, the defoamer feeding device for lubricating oil production disclosed in this utility model can automatically add the defoamer from the storage tank 2 into the feeding cylinder 12 by pulling up the sealing pressure plate 15 through negative pressure, without the need for frequent feeding, thus saving manpower.

[0020] Furthermore, the top feeding port of the storage tank 2 is detachably equipped with a sealing cover 3, and the storage tank 2 is filled with defoamer for easy feeding; furthermore, the quantitative extrusion assembly includes a sealing pressure plate 15 that is sealed and slidably connected to the inner wall of the feeding cylinder 12, and a sliding column 9 is fixedly installed on the top of the sealing pressure plate 15. The sliding column 9 is sealed and slidably connected to the sliding hole at the top of the feeding cylinder 12 to prevent a large amount of material from overflowing from the sliding point; furthermore, a top bar 8 is fixedly installed on the top of the sliding column 9, and an electric telescopic rod 7 is installed at the bottom of the other end of the top bar 8 for easy driving; furthermore, an infrared ranging sensor receiver 10 is embedded in the top of the feeding cylinder 12, and an infrared ranging sensor transmitter 11 is embedded in the corresponding position at the bottom of the top bar 8, which can verify the distance that the sealing pressure plate 15 slides downward in the feeding cylinder 12; furthermore, both the sliding column 9 and the sealing pressure plate 15 are made of stainless steel, which has a long service life and is not easily corroded.

[0021] In this solution, during use, the defoamer feeding device for lubricating oil production disclosed in this utility model, after quantitatively adding defoamer into the reaction tank 1 through the feeding cylinder 12, automatically adds the defoamer from the storage tank 2 into the feeding cylinder 12 by pulling up the sealing pressure plate 15 through negative pressure. This eliminates the need for frequent feeding, saving manpower. When an appropriate amount of defoamer needs to be added into the reaction tank 1, an external power supply controls the electric telescopic rod 7 to shorten to a fixed length via an external switch. The top of the electric telescopic rod 7, connected to the top bar 8, slides downwards in the sliding hole at the top of the feeding cylinder 12. The sealing pressure plate 15 at the bottom of the sliding rod 9 also slides downwards a certain distance within the feeding cylinder 12, causing the appropriate amount of defoamer in the feeding cylinder 12 to be squeezed into the reaction tank 1 through the discharge pipe 5 and the one-way discharge valve 14 at the discharge port, until the infrared light at the bottom of the top bar 8 illuminates. The ranging sensor transmitter 11 works in conjunction with the infrared ranging sensor receiver 10 at the top of the feeding cylinder 12 to detect the distance set in the external control panel. This verifies the distance the sealing pressure plate 15 slides downwards in the feeding cylinder 12. When the defoamer in the feeding cylinder 12 is squeezed out, that is, when the sealing pressure plate 15 slides to the bottom of the feeding cylinder 12, it is necessary to add material to the feeding cylinder 12. The electric telescopic rod 7 is extended by an external switch to slowly slide the sealing pressure plate 15 upwards to reset it. At the same time, a negative pressure is formed to draw the defoamer in the storage tank 2 into the feeding cylinder 12 through the feed pipe 4 at the bottom feed port of the feeding cylinder 12 and the one-way feed valve 13 (the electric telescopic rod 7, the infrared ranging sensor transmitter 11, the infrared ranging sensor receiver 10, the one-way feed valve 13 and the one-way discharge valve 14 are all existing products on the market).
