Description

Technical Field

[0001] This utility model belongs to the field of oil reservoir filling technology, specifically relating to an oil filling device for an oil reservoir used in a magnetic separator. Background Technology

[0002] The magnetic separator's lubrication system uses an automatic oiler to inject lubricating oil into the copper tiles at regular intervals and in measured quantities for lubrication and protection. The oil reservoir, a key component, serves to store the lubricating oil. It is a disposable item, and is purchased pre-filled oil reservoirs.

[0003] When the grease is used up, a new oil reservoir needs to be installed. In order to save on equipment maintenance and operation costs and to improve the efficiency of enterprise management, it is necessary to reuse the discarded oil reservoirs.

[0004] Currently, when filling the reservoir with glycerin, it is usually done manually using a glycerin gun. Since the reservoir volume is about 1 liter, and the reservoir needs to expand and contract during operation, the base material is relatively soft. The diameter of the injection hole is also small, only 3-4 millimeters. Therefore, it takes two workers to fill the reservoir with glycerin using a glycerin gun, and it takes more than an hour to fill one reservoir. At the same time, because the diameter of the glycerin gun outlet and the reservoir injection hole is small, they cannot be properly aligned, making the filling process very difficult. The amount of glycerin injected and the interval between injections cannot be quantified, resulting in serious glycerin waste and oil stains all over the site, which is time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of this invention is to provide an oil filling mechanism for an oil reservoir used in magnetic separators.

[0006] The device can reuse empty oil storage bladders for refilling, and the amount of oil filled can be accurately controlled, saving time and effort.

[0007] This utility model discloses an oil injection device for an oil reservoir of a magnetic separator, characterized in that it includes an oil injector body, a base support, a support frame, an oil injection mechanism, and an oil reservoir. The oil injector body is fixed to the upper end of the base support. The oil injection mechanism includes a lifting adjustment component and a drive mechanism. The lifting adjustment component includes a piston, a threaded guide post, and a scale. The piston is placed inside the oil injector body. The lower end of the threaded guide post is fixedly connected to the piston. The scale is an inverted L-shaped scale composed of a scale horizontal bar and a scale vertical bar. The outer end of the scale horizontal bar is vertically fixedly connected to the upper end of the threaded guide post, so that the scale vertical bar and the threaded guide post are arranged parallel to each other on the outside of the oil injector body.

[0008] The drive mechanism is mounted on a support frame and consists of a motor and a worm gear. The worm gear is connected to the output end of the motor via a coupling, and the other end of the worm gear is linked to a threaded guide post. An oil outlet is provided at the bottom center of the oil injector body, and the oil outlet is connected to a filling pipe. A control valve is provided on the filling pipe.

[0009] A limit switch is provided at the lower part of the vertical rod of the scale, and a contact switch is provided at the lower part of the refueling pipe away from the refueling pipe.

[0010] Preferably, the refueling pipe is a conical refueling pipe with external threads.

[0011] Preferably, the oil reservoir is a retractable rubber oil reservoir.

[0012] Preferably, a rubber sealing ring is embedded in the outer circumference of the piston.

[0013] The advantages of this utility model are:

[0014] Compared with the prior art, the oil injection device of this invention not only solves the problems of manual oiling being very difficult, the inability to quantify the amount of oil injected and the interval between injections, and the serious waste of glycerin, but also makes the oiling process more convenient and reliable, saving time and effort.

[0015] This invention can inject oil into reusable empty oil storage bladders, and the amount of oil injected can be accurately controlled, saving time and effort. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figure 1 As shown, this utility model discloses an oil injection device for an oil reservoir bladder used in a magnetic separator. The device comprises an oil injector body 1, a base support 2, a support frame 3, an oil injection mechanism, and an oil reservoir 11. The oil injector body 1 is fixed to the upper end of the base support 2, which is a triangular base support whose height can be determined according to the size of the oil reservoir bladder. The oil reservoir bladder is a retractable rubber oil reservoir bladder. The oil injection mechanism includes a lifting adjustment component and a drive mechanism. The lifting adjustment component includes a piston 41, a threaded guide post 42, and a scale. The piston 41 is placed inside the oil injector body 1. The lower end of the threaded guide post 42 is fixedly connected to the piston 41. A rubber sealing ring 9 is embedded in the outer circumference of the piston 31 to ensure good sealing between the piston 31 and the inner wall of the oil injector body 1.

[0019] The scale described in this utility model is an inverted L-shaped scale composed of a scale horizontal bar 431 and a scale vertical bar 432. The outer end of the scale horizontal bar 431 is vertically and fixedly connected to the upper end of the threaded guide post 42, so that the scale vertical bar 432 and the threaded guide post 42 are arranged parallel to each other on the outside of the oiler body 1. A limit switch 9 is provided at the lower part of the scale vertical bar 432. When the grease in the oiler body 1 reaches the lower limit of use, the scale will trigger the limit switch to stop the oiling device from operating, thereby preventing damage to the oiling device.

[0020] This invention features a contact switch 7 located at the lower part of the refueling pipe 12, away from the refueling pipe itself. The contact switch 7 is used to trip the oil reservoir 6 when it is filled with oil, causing the reservoir to stretch and triggering a power cut-off. This allows for accurate control of the refueling volume, saving time and effort.

[0021] The drive mechanism is mounted on the support frame 3 and consists of a motor 51 and a worm gear 52. The worm gear 52 is connected to the output end of the motor 51 via a coupling 53, and the other end of the worm gear 52 is linked to a threaded guide post 42. An oil outlet 11 is provided at the bottom center of the oil injector body 1, and the oil outlet is connected to a filling pipe 12. A control valve 13 is provided on the filling pipe 12. The control valve 13 is used to control the oil output.

[0022] The present invention features a conical refueling pipe 12 with external threads. This conical refueling pipe with external threads facilitates insertion into the oil inlet of the oil reservoir.

[0023] The novel motor, limit switch 9, and control valve 13 are all electrically connected to the automatic control system. Since the automatic control system is existing technology, it will not be described in detail here.

[0024] In use, first add grease 10 to the injector body 1. After connecting the oil inlet of the oil reservoir 11 to the filling pipe, open valve 13 and start the motor. After the motor 51 starts, it drives the worm gear 52 to rotate. The worm gear 52 drives the threaded guide post 42 to move up and down. The up and down movement of the threaded guide post 42 adjusts the piston 41 inside the injector body 1, causing the piston 41 to squeeze the grease downwards. The grease is injected into the oil reservoir 11 through the oil outlet 11 and the filling pipe. When the oil reservoir 11 is full of grease and stretched, it triggers the contact switch 7, de-energizing the motor and stopping the injection. This is very convenient for manual operation. When injection is not needed, the valve can be manually closed.
