Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of lubricating oil production equipment, specifically a negative pressure recovery device for residual liquid in lubricating oil filling nozzles. Background Technology
[0002] Lubricating oil has the functions of lubrication, rust prevention, sealing and buffering. It is used in various automobiles and mechanical equipment to reduce friction and wear between contacting parts and ensure the normal operation of automobiles and mechanical equipment. Most lubricating oil manufacturers use fully automated production and filling lines.
[0003] According to the announcement number CN215711721U, a negative pressure recovery device for residual lubricating oil filling nozzles includes a cylindrical glass collection cylinder and a filling nozzle. A negative pressure pipe is installed on the upper surface of the cylindrical glass collection cylinder, and a solenoid valve is installed on the negative pressure pipe. An annular collection groove is installed on the outer surface of the filling nozzle. The upper surface of the cylindrical glass collection cylinder is connected to the annular collection groove through a return pipe. This device can effectively collect residual lubricating oil at the outlet of the filling nozzle, preventing lubricating oil from dripping onto the filling table, effectively improving filling accuracy and efficiency. The cylindrical glass collection cylinder can collect residual lubricating oil inside the filling nozzle. The position of the cylindrical glass collection cylinder can be fixed by a first mounting base and a second mounting base. The airflow discharged from the air nozzle can purge the oil in the feeding channel. The lifting and lowering of the feeding channel and the collection channel can be quickly adjusted by a pneumatic telescopic rod.
[0004] The aforementioned device can effectively collect residual lubricating oil from the filling nozzle outlet, preventing lubricating oil from dripping onto the filling table, thus improving filling accuracy and efficiency. However, when the return pipe is processing residual lubricating oil, the lubricating oil, due to its viscosity, may adhere to the inner wall of the pipe. Over time, this may gradually accumulate, causing the pipe to narrow or even become blocked, affecting the recovery of residual liquid and the normal operation of the equipment. As can be seen from the attached diagram, the return pipe of this device is fixedly connected and cannot be cleaned when blocked, which will affect the use of the equipment. Utility Model Content
[0005] The purpose of this invention is to address the problem that while the aforementioned device can effectively collect residual lubricating oil from the filling nozzle outlet, preventing it from dripping onto the filling table and thus improving filling accuracy and efficiency, the lubricating oil, due to its viscosity, may adhere to the inner wall of the return pipe during processing. Over time, this accumulation can narrow the pipe or even cause blockage, affecting the recovery of residual liquid and the normal operation of the equipment. As can be seen from the attached drawings, the return pipe of this device is fixedly connected and cannot be cleaned when blocked, which affects the use of the equipment. Therefore, this invention provides a negative pressure recovery device for residual lubricating oil from filling nozzles.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a negative pressure recovery device for residual liquid in a lubricating oil filling nozzle, comprising a mounting base and a protective shell. The mounting bases are symmetrically arranged, and a collection cylinder is fixedly installed in the middle of the two sets of mounting bases. An oil collecting cylinder is fixedly installed at the bottom of the protective shell. A return pipe is provided at one end of the oil collecting cylinder and at the middle of the top of the mounting base. A collection hole is opened at one end of the oil collecting cylinder, and a collection groove is opened inside the oil collecting cylinder. The collection hole passes through the oil collecting cylinder and is connected to the collection groove. A disassembly assembly is provided in the middle of the return pipe and the collection hole. The disassembly assembly includes a first locking block fixedly installed with the return pipe, a second locking block fixedly installed at one end of the collection hole, and a limiting block one symmetrically fixedly installed on the outer periphery of the first locking block. A limiting block two is symmetrically fixedly installed on the outer periphery of the first locking block. A first limiting block that rotates and engages with the first locking block is symmetrically fixedly installed on the outer periphery of the second locking block. A second limiting block that rotates and engages with the second locking block is symmetrically fixedly installed on the outer periphery of the first locking block. The bottom ends of the limiting block one and the limiting block two are provided with slots for limiting the second limiting block and the first limiting block.
[0007] As a further improvement of this utility model: the top of the second limiting block and the outer periphery of the first card block are both provided with limiting grooves for limiting, and the top of the second limiting block is threaded with a limiting rod that matches the limiting groove.
[0008] As a further improvement of this utility model: a filter screen plate for filtering impurities is fixedly installed inside the first card block and on one side of the return pipe.
[0009] As a further embodiment of this utility model: a heating chamber is provided inside the oil collecting cylinder and on the outer periphery of the collecting trough, and heating wires for heating are uniformly arranged around the inside of the heating chamber.
[0010] As a further improvement of this utility model, a power socket for supplying power to a heating wire is fixedly installed at one end of the oil collecting cylinder.
[0011] As a further improvement of this utility model: support rods for support are evenly installed around the middle of the two sets of mounting seats, and a negative pressure valve is fixedly installed at the top of the mounting seat.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] In this invention, the heating wire inside the heating chamber can heat the recovered lubricating oil residue during the recovery process, thereby reducing the difficulty of recovery caused by the lubricating oil cooling and solidifying in the collection tank, and reducing the blockage caused by the lubricating oil residue cooling and solidifying in the collection tank.
[0014] In this invention, the return pipe can be quickly disassembled from one side of the oil collecting cylinder and the top of the collecting cylinder by disassembling the components. This facilitates quick replacement when the return pipe is blocked by residual lubricating oil impurities, thereby increasing the efficiency of the equipment. Attached Figure Description

The embodiments of this utility model will be described below based on its overall structure.
[0022] Reference Figures 1 to 4 In this embodiment of the present invention, a negative pressure recovery device for residual liquid in a lubricating oil filling nozzle includes a mounting base 1 and a protective shell 4. The mounting bases 1 are symmetrically arranged, and a collection cylinder 2 is fixedly installed in the middle of the two sets of mounting bases 1. An oil collecting cylinder 5 is fixedly installed at the bottom of the protective shell 4. A return pipe 6 is provided at one end of the oil collecting cylinder 5 and at the middle of the top of the mounting base 1. A collection hole 8 is opened at one end of the oil collecting cylinder 5, and a collection groove 9 is opened inside the oil collecting cylinder 5. The collection hole 8 passes through the oil collecting cylinder 5 and connects it to the collection groove 9. A disassembly component 7 is provided in the middle of the return pipe 6 and the collection hole 8. The disassembly component 7 includes components fixed to the return pipe 6. The device includes a first locking block 72, a second locking block 71 fixedly installed at one end of the collection hole 8, and a first limiting block 73 symmetrically fixedly installed on the outer periphery of the first locking block 72. A second limiting block 74 is symmetrically fixedly installed on the outer periphery of the first locking block 72. A first limiting block 75 that rotates and engages with the first locking block 72 is symmetrically fixedly installed on the outer periphery of the second locking block 71. A second limiting block 77 that rotates and engages with the second locking block 71 is symmetrically fixedly installed on the outer periphery of the first locking block 72. The bottom ends of the first limiting block 73 and the second limiting block 74 are provided with slots 76 for limiting the second limiting block 77 and the first limiting block 75.
[0023] The above scheme is adopted: the other end of the return pipe 6 is also equipped with a disassembly component 7 at the top of the mounting base 1. The return pipe 6 passes through the mounting base 1 and is connected to the collection cylinder 2. The bottom end of the collection cylinder 2 is equipped with a discharge pipe (not marked in the figure), and a solenoid valve for controlling the discharge is set on the outer periphery of the discharge pipe. The slot 76, the first limit block 75 and the second limit block 77 are all equipped with anti-slip layers to increase the stability of the snap-fit. The anti-slip layers of the slot 76, the first limit block 75 and the second limit block 77 are set in opposite directions. The disassembly component 7 can quickly disassemble the return pipe 6 from one side of the oil collection cylinder 5 and the top of the collection cylinder 2, which is convenient for quick replacement when the return pipe 6 is blocked by residual lubricating oil impurities, thereby increasing the efficiency of the equipment.
[0024] Reference Figures 1 to 4 The top of the second limiting block 74 and the outer periphery of the first locking block 72 are both provided with limiting grooves 78 for limiting, and the top of the second limiting block 74 is threadedly connected with a limiting rod 79 that is adapted to the limiting groove 78.
[0025] By adopting the above solution, the situation where the first locking block 72 and the second locking block 71 are accidentally rotated due to accidental contact can be reduced, which could cause the return pipe 6 and the oil collection cylinder 5 to fall off.
[0026] Reference Figures 1 to 4 A filter screen plate 710 for filtering impurities is fixedly installed inside the first card block 72 and on one side of the return pipe 6.
[0027] The above solution effectively intercepts particulate impurities, metal shavings, dust, etc. in the residual lubricating oil through the filter screen 710, preventing these impurities from flowing back through the return pipe 6 with the residual oil. This ensures that the returned lubricating oil is relatively pure and reduces the impact of impurities on subsequent recycling equipment or reuse.
[0028] Reference Figures 1 to 4 A heating chamber 711 is provided inside the oil collecting cylinder 5 and on the outer periphery of the collecting trough 9. A heating wire 712 for heating is evenly arranged inside the heating chamber 711. A power socket 713 for powering the heating wire 712 is fixedly installed at one end of the oil collecting cylinder 5.
[0029] The above scheme is adopted: the collection hole 8 is connected to the oil collection cylinder 5 and the heating chamber 711 and the collection tank 9. The heating wire 712 is installed inside the heating chamber 711 to facilitate uniform heating of the lubricating oil residue collected in the collection tank 9. The heating wire 712 inside the heating chamber 711 can heat the recovered lubricating fluid when recovering the lubricating oil residue, reducing the difficulty of recovery caused by the lubricating oil cooling and solidifying in the collection tank 9, and reducing the phenomenon of blockage caused by the lubricating oil residue cooling and solidifying in the collection tank.
[0030] Reference Figures 1 to 4 Two sets of mounting bases 1 are evenly surrounded by support rods 10 for support, and a negative pressure valve 3 is fixedly installed at the top of the mounting base 1.
[0031] The working principle of this utility model is as follows: During use, the heating wire 712 inside the oil collecting cylinder 5 is first energized and heated via the power socket 713. The heating wire 712 inside the heating chamber 711 heats the recovered lubricating oil residue, reducing the likelihood of lubricating oil solidifying in the collecting tank 9 and causing blockages. Then, the first locking block 72 at one end of the return pipe 6 contacts the contact surface of the second locking block 71 at one end of the collecting hole 8. After rotating the first locking block 72, the slot 76 at the bottom of the limiting block 74 on the outer periphery of the first locking block 72 will engage with the outer surface of the second locking block 71. The first limiting block 75 of the first locking block 72 engages with the second limiting block 73 on the outer periphery of the second locking block 71. The groove 76 at the bottom of the limiting block 73 on the outer periphery of the second locking block 73 engages with the second limiting block 77 on the outer periphery of the first locking block 72. Through this double engagement, the return pipe 6 can be quickly installed to the collection hole 8 at one end of the oil collecting cylinder 5. When disassembling, simply rotate the first locking block 72 in the opposite direction to quickly separate the return pipe 6 from the second locking block 71. The disassembly assembly 7 can quickly remove the return pipe 6 from one side of the oil collecting cylinder 5 and the top of the collecting cylinder 2, which is convenient for quick replacement when the return pipe 6 is blocked by residual lubricating oil impurities, thus increasing the efficiency of the equipment.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
