Description

Technical Field

[0001] The present application relates to the technical field of lubricating oil production, and specifically to a feeding device for lubricating oil production. Background Art

[0002] Lubricating oil is a liquid or semi-solid lubricant used on various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays roles such as lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and buffering. Lubricating oil generally consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, and the additives can make up for and improve the deficiencies in the performance of the base oil, endowing some new properties, and are an important part of lubricating oil. During the production process of lubricating oil, various additives and base oil need to be put into a mixing drum for stirring to make them fully blended.

[0003] Chinese Patent Authorization Publication No.: CN221132133U discloses a feeding device for lubricating oil production. Through the cooperation of the feeding box on the feeding assembly and the speed control assembly, the speed at which the fed raw materials fall into the mixer can be more precisely controlled, so as to control the amount of raw materials entering the mixer. When the speed control assembly makes the opening of the feeding box leading to the mixer larger, the raw materials slide down from the feeding box faster; when the speed control assembly makes the opening of the feeding box leading to the mixer smaller, the raw materials slide down from the feeding box slower. The raw materials can be put into the raw material crushing assembly to crush the raw materials.

[0004] However, when the liquid level of the raw materials in the mixing drum is relatively low, there is a certain distance between the feeding port and the liquid level of the lubricating oil raw materials. At this time, when the additives are discharged through the feeding port, the gravity of the additives falling will increase, which will drive a large amount of air to be involved, resulting in a large number of bubbles in the lubricating oil raw materials in the mixing drum. The existence of bubbles hinders the full mixing of the lubricating oil components, thus affecting the uniformity and quality during the mixing process, and ultimately reducing the performance and stability of the lubricating oil.

[0005] Therefore, it is necessary to provide a feeding device for lubricating oil production to solve the above problems.

[0006] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of the present application, and therefore, it may include information that does not constitute the prior art. Summary of the Utility Model

[0007] Based on the above problems existing in the prior art, the problem to be solved by this application is to provide a feeding device for lubricating oil production. By using a driving member to control the rotation of a screw rod, the lifting plate can smoothly rise in the vertical direction, so that the height of the feeding pipe can rise as the liquid level in the feeding hopper increases, reducing the generation of bubbles caused by the liquid level difference. The reduction of bubbles makes the mixing process more uniform, which helps to maintain the uniformity and stability of the lubricating oil.

[0010] Further, a partition plate is installed inside the feeding hopper. The partition plate divides the inner cavity of the feeding hopper into a feeding cavity and a filtering cavity. A filtering mechanism is installed inside the filtering cavity.

[0011] Further, the filtering mechanism includes a drum. The drum is installed on the partition plate, and a plurality of fan-shaped grooves are provided on the drum. A filter cylinder is detachably installed inside the drum.

[0012] Further, the filtering mechanism further includes a power source for driving the rotation of the drum. The drum is rotatably connected to the partition plate.

[0013] Further, the power source includes a second motor installed on the partition plate.

[0014] Further, there is a gap between the bottom of the drum and the bottom of the inner cavity of the feeding hopper.

[0015] Further, the filter cylinder is made of stainless steel.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine with the embodiments to elaborate on the present application in detail.

[0028] To enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0029] As Figures 1-5 shown, this application provides a feeding device for lubricating oil production, including: a feeding hopper 1 and a lifting mechanism 2. A telescopic pipe 3 is installed at the bottom of the feeding hopper 1 and is connected to it in a communicating manner. The telescopic pipe 3 can be fixedly connected to the feeding hopper 1 by a flange. The telescopic pipe 3 can be a corrugated pipe and can be telescoped along with the movement of the feeding pipe 4. One end of the telescopic pipe 3 away from the feeding hopper 1 is installed with a feeding pipe 4, and the feeding pipe 4 is also fixedly connected to the telescopic pipe 3 by a flange. The lifting mechanism 2 includes a screw rod 21, a sliding rod 22, and a lifting plate 23. The feeding pipe 4 is installed at the bottom of the lifting plate 23, and the feeding pipe 4 can be fixedly connected to the lifting plate 23 by welding. The screw rod 21 is rotatably connected to the bottom of the feeding hopper 1, the sliding rod 22 is fixed to the bottom of the feeding hopper 1, the lifting plate 23 is slidably connected to the sliding rod 22, and a screw sleeve matching the screw rod 21 is installed inside the lifting plate 23; wherein, the lifting mechanism 2 further includes a driving member for driving the screw rod 21 to rotate.

[0030] In this embodiment, this solution is a device for putting base oil and additives into a mixing tank during the production process of lubricating oil for full stirring and mixing. Specifically, by installing the feeding hopper 1 on the top of the mixing tank and using the driving member to control the lifting of the lifting plate 23, the feeding pipe 4 is made close to the liquid level of the raw materials inside the mixing tank. Subsequently, the base oil or additives to be put are poured into the feeding hopper 1, and the raw materials are then transported through the telescopic pipe 3 into the feeding pipe 4 and finally discharged into the mixing tank. Then, during the feeding process, the screw rod 21 can be rotated by using the driving member, so that the lifting plate 23 rises smoothly in the vertical direction, enabling the height of the feeding pipe 4 to rise as the liquid level in the feeding hopper 1 increases, reducing the generation of bubbles caused by the liquid level difference. The reduction of bubbles helps to maintain the uniformity and stability of the lubricating oil.

[0031] It should be noted that the feeding hopper 1 can be fixed on the top of the mixing tank near the edge by bolts, so as to avoid blocking the stirring mechanism inside the mixing tank, and a transparent observation window needs to be opened on the outer side wall of the mixing tank to facilitate knowing the liquid level of the raw materials inside the mixing tank.

[0032] As Figure 3As shown in the figure, the driving member includes a first motor 24 installed at the bottom of the feeding hopper 1. The first motor 24 can be fixed to the bottom of the feeding hopper 1 by bolts. A driving gear 25 is installed at the output end of the first motor 24. A driven gear 26 meshing with the driving gear 25 is installed on the outer side wall of the screw 21. The driven gear 26 is fixedly sleeved on the outer side wall of the screw 21.

[0033] In this embodiment, by setting the first motor 24, the driving gear 25 can be controlled to rotate. Under the meshing connection of the driving gear 25 and the driven gear 26, the screw 21 is synchronously driven to rotate, so as to realize the vertical movement of the lifting plate 23. And the rising speed of the lifting plate 23 can be adjusted by adjusting the rotation speed of the first motor 24.

[0034] As Figures 4-5 As shown in the figure, a partition plate 6 is installed inside the feeding hopper 1. The partition plate 6 is fixed inside the feeding hopper 1 by welding. The partition plate 6 divides the inner cavity of the feeding hopper 1 into a feeding cavity and a filtering cavity. A filtering mechanism 5 is installed inside the filtering cavity. The filtering mechanism 5 includes a drum 51. The drum 51 is installed on the partition plate 6, and a plurality of fan-shaped grooves 56 are formed on the drum 51. A filter cylinder 52 is detachably installed inside the drum 51. The filtering mechanism 5 further includes a power source for driving the rotation of the drum 51. The drum 51 is rotatably connected to the partition plate 6. The power source includes a second motor 53 installed on the partition plate 6. The second motor 53 is fixed to the top of the partition plate 6 by bolts. The output end of the second motor 53 penetrates through the partition plate 6 and a transmission gear 54 is installed. An external gear ring 55 meshing with the transmission gear 54 is installed on the outer side wall of the drum 51. The external gear ring 55 is fixed to the outer side wall of the drum 51 by welding. A gap is provided between the bottom of the drum 51 and the bottom of the inner cavity of the feeding hopper 1. The filter cylinder 52 is made of stainless steel material to improve the service life of the filter cylinder 52.

[0035] In this embodiment, the base oil or additive to be put in can be poured into the feeding hopper 1, and the raw materials are discharged into the filter cylinder 52. And the second motor 53 is used to control the transmission gear 54 to rotate. Under the meshing connection of the transmission gear 54 and the external gear ring 55, the drum 51 and the internal filter cylinder 52 are driven to rotate, so that the raw materials do centrifugal motion in the filter cylinder 52. The filter cylinder 52 can intercept large particle impurities, achieving an effective filtering effect and further improving the quality of the lubricating oil. The filtered raw materials are then discharged into the feeding pipe 4 through the telescopic pipe 3 and finally put into the mixing tank.

[0036] Among them, the filter cylinder 52 can be installed inside the drum 51 by bolts or snap-fastening. With this detachable structure, it is convenient to clean the drum 51.

[0037] Working principle:

[0038] The lifting plate 23 is controlled by a driving member to lift and lower, so that the feeding pipe 4 is close to the liquid level of the raw materials inside the stirring tank. Then, the base oil or additive to be put in is poured into the feeding hopper 1, and the raw materials are discharged into the filter cylinder 52. Moreover, the second motor 53 is used to control the transmission gear 54 to rotate. Under the meshing connection of the transmission gear 54 and the external gear ring 55, the roller 51 and the internal filter cylinder 52 are driven to rotate, so that the raw materials do centrifugal motion in the filter cylinder 52. The filter cylinder 52 can intercept large-particle impurities, achieving an effective filtering effect and further improving the quality of the lubricating oil. The filtered raw materials are then discharged into the feeding pipe 4 through the telescopic pipe 3. During the feeding process, the driving member can be used to control the screw rod 21 to rotate, so that the lifting plate 23 rises stably in the vertical direction, and the height of the feeding pipe 4 can rise as the liquid level in the feeding hopper 1 rises, reducing the generation of bubbles caused by the liquid level difference.

[0039] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
