Description

Technical Field

[0001] This invention relates to the field of lubricating oil technology, and in particular to a raw material crushing device for lubricating oil production. Background Technology

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It is generally composed of two parts: base oil and additives. The production process of lubricating oil requires the raw materials to be crushed and mixed.

[0003] Existing technology, Chinese Patent Application No. 202222810860.4, discloses a material crushing device for lubricating oil production. The device includes a crushing chamber mounted on a reactor vessel. A first motor is fixedly connected to the side of the crushing chamber, and the output end of the first motor is driven by a crushing shaft. The other end of the crushing shaft is rotatably connected to the inner wall of the crushing chamber via a bearing seat. A heating shell is provided outside the crushing shaft, and a heating plate is installed inside the heating shell. Spiral pulverizing blades are provided on the surface of the heating shell to effectively prevent the raw materials from clumping. A second motor is fixedly connected to the bottom of the reactor vessel, and a rotating shaft is fixedly connected to the output end of the second motor. A stirring rod is fixedly connected to the bottom of the outer surface of the rotating shaft, and the rotating shaft penetrates the reactor vessel to the top of the outer surface of the crushing chamber, where a pulverizing rod is fixedly connected, thus achieving the crushing treatment of the raw materials.

[0004] Although the above patents have achieved the crushing of raw materials for lubricant production, there are still some shortcomings: the stirring rod can only stir materials at the same height during stirring, and cannot stir from top to bottom, which will lead to uneven mixing of raw materials.

Detailed Implementation

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0035] As a specific implementation method of this embodiment, such as Figure 4 and Figure 6As shown, gear set 107 includes gear 2, gear 3, gear 4, and gear 5; gear 2, gear 3, gear 4, and gear 5 are all rotatably mounted on the feed box 101; gear 2 is fixedly connected to one of its spiral feed plates 102; gear 2 meshes with gear 3; gear 3 meshes with gear 4, and gear 4 meshes with gear 5; one end of gear 5 is fixedly connected to another spiral feed plate 102, and the other end is fixedly connected to the output end of motor 103; motor 103 drives the two spiral feed plates 102 to rotate synchronously through gear set 107, and the two spiral feed plates 102 rotate in opposite directions; this enables better preliminary crushing and transportation of raw materials;

[0036] The upper end of the feeding box 101 is provided with two feed inlets corresponding to one end of the two spiral feeding plates 102, and the lower end of the feeding box 101 is provided with a discharge outlet corresponding to the other end of the two spiral feeding plates 102; the crushing mechanism 2 is fixedly installed below the feeding box 101 corresponding to the discharge outlet.

[0037] In order to increase the conveying capacity of the feeding mechanism 1, such as Figure 3 and Figures 6-9 As shown, the feeding mechanism 1 also includes: a lead screw 104 and a fixed plate 108; the number of lead screws 104 and fixed plates 108 is the same as that of the spiral feeding plates 102, both being two, and they are respectively located at the center position of the spiral feeding plates 102, that is, one lead screw 104 and one fixed plate 108 are correspondingly installed at the center position of one spiral feeding plate 102; the two lead screws 104 are rotatably mounted on the conveying box 101 and are connected by a belt 106, and are synchronously driven by a motor 105 fixedly mounted on the conveying box 101;

[0039] As a specific implementation of the text example, such as Figures 8-9As shown, gear set 2 112 includes: gear 6, gear 7, belt 4 and belt 5; gear 6 and gear 7 are rotatably mounted on slider 109 and mesh with each other; gear 6 is connected to one of the pusher plates 110 via belt 4, and gear 7 is connected to the other pusher plate 110 via belt 5; motor 3 111 is fixedly mounted on slider 109, and the output end of motor 3 111 is fixedly connected to gear 6, and motor 3 111 drives the two pusher plates 110 to rotate.

[0040] After different lubricating oil raw materials are fed into the equipment through the feed inlet, motor 103 drives gear set 107 to rotate, which in turn drives the spiral feeder 102 to rotate. While conveying the materials, it also completes the mixing and loosening of different materials and crushes the lumpy materials. Motor 2 105 drives the lead screw 104 to rotate, and the lead screw 104 drives the slider 109 to slide to the right on the fixed plate 108. At this time, the two pusher plates 110 are in the initial state and are V-shaped, which reduces the resistance of the raw materials to the pusher plates 110. When it slides to the rightmost end, motor 3 111 drives gear set 2 112 to rotate, which causes gear set 2 112 to drive the pusher plates 110 to rotate from the V shape to the two pusher plates 110 being on the same plane. Then motor 2 105 rotates in the opposite direction, and through the lead screw 104, it drives the pusher plates 110 on the slider 109 to push the lubricating oil raw materials to the left, so that the lubricating oil raw materials fall from the discharge outlet into the crushing mechanism 2. This process is repeated.

[0044] Specifically, such as Figures 11-21As shown, the stirring mechanism 3 includes: a stirring tank 301, a transmission assembly 305, stirring blades 306, a lifting rod assembly 307, and a sliding rod 308; the stirring tank 301 is fixedly installed on the mounting frame and located below the crushing box 201; the upper end of the stirring tank 301 is provided with a feed inlet 3, which corresponds to the discharge outlet 2, and the lower end is provided with a discharge outlet 3; the upper end of the stirring tank 301 is provided with a horizontal mounting bracket, on which a stirring shaft 302 is rotatably mounted and driven by a motor 5 303 fixedly mounted on the horizontal mounting bracket; a sliding cylinder 304 is vertically slidably mounted on the horizontal mounting bracket of the stirring tank 301; the sliding cylinder 304 is connected to the stirring shaft 302 through the transmission assembly 305 mounted on the horizontal mounting bracket; while the motor 5 303 drives the stirring shaft 302 to rotate, the stirring shaft 302 drives the sliding cylinder 304 to slide up and down reciprocally.

[0045] As a specific implementation method of this embodiment, such as Figures 13-14 and Figure 17 As shown, the transmission assembly 305 includes: a first bevel gear 3051, a second bevel gear 3052, and a lifting crossbar 3056; the first bevel gear 3051 is rotatably mounted on the horizontal mounting bracket of the mixing tank 301 and is connected to the mixing shaft 302 via a third belt 3057; the second bevel gear 3052 is rotatably mounted on the horizontal mounting bracket of the mixing tank 301 and is connected to the rotating block 3054 rotatably mounted on the horizontal mounting bracket via a second belt 3053; the first bevel gear 3051 and the second bevel gear 3052 mesh with each other; the lifting crossbar 3056 is fixedly connected to the slide cylinder 304; the lifting crossbar 3056 has a horizontal groove in the middle; one end of the rotating block 3054 is rotatably mounted on the horizontal mounting bracket of the mixing tank 301, and a sliding block 3055 is rotatably mounted on the other end; the sliding block 3055 is horizontally slidably mounted in the horizontal groove of the lifting crossbar 3056;

[0046] Motor 303 drives the stirring shaft 302 to rotate, and the stirring shaft 302 drives the rotating block 3054 to rotate circumferentially; the rotating block 3054 drives the lifting crossbar 3056 to slide up and down reciprocally.

[0047] The bottom of the slide cylinder 304 is provided with a circumferential sliding groove; the lifting rod assembly 307 is vertically slidably mounted on the stirring shaft 302, and its upper end is rotatably mounted in the circumferential sliding groove on the slide cylinder 304; the lifting rod assembly 307 is provided with three lifting rods;

[0048] In order to make the raw materials in the mixing tank 301 more evenly, the mixing shaft 302 is divided into three mixing zones from top to bottom. Each mixing zone has three mixing blades 306 that are rotatably mounted on the mixing shaft 302 in correspondence with three lifting rods.

[0049] The number of slide rods 308 is equal to the number of stirring blades 306, both being nine; the slide rods 308 and stirring blades 306 correspond one-to-one; one end of the slide rod 308 is movably connected to the stirring shaft 302 through a collar, and the other end is slidably connected to one end of the stirring blade 306;

[0051] After being crushed, the lubricating oil raw material enters the mixing tank 301. The motor 303 rotates, driving the mixing shaft 302 to rotate. The mixing shaft 302 drives the mixing blades 306 to rotate horizontally, stirring the crushed lubricating oil raw material. At the same time, the mixing shaft 302 drives the slide 304 to move up and down through the transmission assembly 305. The slide 304 drives the lifting rod assembly 307 to move up and down reciprocally. The lifting rod assembly 307 drives the slide rod 308 to slide inside the mixing blades 306, thereby driving the mixing blades 306 to rotate reciprocally in the vertical direction. Because the mixing blades 306 rotate simultaneously in the horizontal and vertical directions, the lubricating oil raw material is stirred, thus making the different lubricating oil raw materials more thoroughly mixed.
