Specific embodiments

[0024] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Such as Figure 1 - Figure 3As shown, a pyrolysis waste oil recovery and environmental protection equipment includes a convex cylinder 1, an exhaust pipe communicating with the inner cavity of the convex cylinder 1 for discharging combustible synthesis gas is provided at the left upper end of the convex cylinder 1, a motor 2 is provided in the middle of the upper end of the convex cylinder 1, the output end of the motor 2 extends to the inner side of the convex cylinder 1 and is provided with a rotating shaft assembly 6, the lower end of the rotating shaft assembly 6 is provided with a heating plate 8 for supporting and pyrolyzing waste oil, and the heating plate 8 is vertically slidably connected in the convex cylinder 1, and the lower part of the outer surface of the rotating shaft assembly 6 is provided with three stirring plates. A mixing assembly 7 is provided, and the three stirring assemblies 7 are distributed in a circular array. An electric push rod 3 for controlling the up and down movement of the rotating shaft assembly 6 and the heating disk 8 is provided on the right upper end of the convex cylinder 1. A feed pipe is provided on the upper outer surface of the convex cylinder 1, and a discharge pipe is provided at the middle lower end of the convex cylinder 1. An annular groove 9 is provided inside the side wall of the vertical part of the convex cylinder 1. An electric heating wire 10 is provided on the inner side of the annular groove 9. The electric heating wire 10 cooperates with the heating disk 8 to increase the heating area of the device to accelerate the pyrolysis of waste grease.

[0026] As can be seen from the above, the waste grease is first injected into the convex cylinder 1 through the feed pipe, and then the heating plate 8 and the electric heating wire 10 are started, and the motor 2 is started at the same time to control the rotation of the shaft assembly 6 and the stirring assembly 7 to stir the waste grease, which not only promotes heat conduction, makes the waste grease heated more evenly, improves the pyrolysis efficiency, but also avoids local overheating of the waste grease and causes premature coking. The combustible synthesis gas generated during the pyrolysis process will leave through the exhaust pipe. Finally, the electric push rod 3 works to control the heating plate 8 to move downward, so that the residue after pyrolysis of the waste grease on the heating plate 8 can fall into the bottom of the convex cylinder 1 through the gap between the heating plate 8 and the inner wall of the horizontal part of the convex cylinder 1 under the action of the stirring assembly 7, so that it can leave through the discharge pipe.

[0027] Furthermore, the bottom wall of the horizontal portion of the convex cylinder 1 is a conical structure with a downward depression in the middle, which is used to promote the departure of liquid oil and a small amount of small solid residue after pyrolysis of waste grease, while also reducing residue.

[0028] Furthermore, a filter frame 4 for intercepting solid residue is provided at the lower inner part of the horizontal part of the convex cylinder 1. The filter frame 4 consists of a frame and a filter, and the filter is installed at the inner bottom of the frame, so that the filter frame 4 can be moved outward for cleaning after intercepting the solid residue. The right end of the filter frame 4 passes through the outer wall of the convex cylinder 1 and extends to the outside of the convex cylinder 1, so as to facilitate the extraction of the filter frame 4 from the convex cylinder 1 and clean the solid residue intercepted by the filter frame 4 to avoid affecting the subsequent departure of liquid oil. In addition, two sealing rings are also provided on the outer surface of the horizontal part of the convex cylinder 1 to maintain a sealed environment for pyrolysis in the convex cylinder 1.

[0029] Specifically, such as Figure 4As shown, limiting sliding grooves 13 are provided on both the left and right inner surfaces of the horizontal part of the convex cylinder 1. Limiting sliding rods 11 are provided on both the lower left and lower right outer surfaces of the heating plate 8. A part of the two limiting sliding rods 11 away from the heating plate 8 is respectively slidably connected in the limiting sliding grooves 13 on the same side, so that the heating plate 8 can only move up and down, preventing the heating plate 8 from rotating together with the rotating shaft assembly 6 and affecting the stirring and discharging effects of the stirring assembly 7.

[0030] Specifically, as Figure 5 shown, the rotating shaft assembly 6 includes a polygonal shaft 61 located inside the convex cylinder 1. The top of the polygonal shaft 61 is connected to the output end of the motor 2. A rotating rod 62 is provided on the outer surface of the polygonal shaft 61. The rotating rod 62 is slidably connected to the polygonal shaft 61. However, the polygonal shaft 61 can drive the rotating rod 62 to rotate by using the side edges and corners on its surface. The lower end of the rotating rod 62 is rotatably connected to the heating plate 8. A connecting plate 5 is provided on the upper part of the outer surface of the rotating rod 62. The output end of the electric push rod 3 passes through the top wall of the convex cylinder 1 and is fixedly connected to the connecting plate 5. The connecting plate 5 is rotatably connected to the rotating rod 62, so that the connecting plate 5 can only control the up and down movement of the rotating rod 62 under the action of the electric push rod 3 and cannot affect the normal rotation of the rotating rod 62;

[0031] It can be seen from this that the motor 2 first controls the rotation of the rotating rod 62 through the polygonal shaft 61, and then the rotating rod 62 stirs the waste grease on the heating plate 8 through the stirring assembly 7. When discharging is required, the electric push rod 3 extends to move the rotating rod 62 and the heating plate 8 downward through the connecting plate 5, so that the residue after the pyrolysis of the waste grease on the heating plate 8 can fall into the bottom of the convex cylinder 1 through the gap between the heating plate 8 and the inner wall of the horizontal part of the convex cylinder 1.

[0032] Specifically, as Figure 5 shown, the stirring assembly 7 includes an L-shaped stirring blade 71 fixedly connected to the bottom of the rotating rod 62. The horizontal part of the L-shaped stirring blade 71 is in close contact with the upper end surface of the heating plate 8, and the vertical part of the L-shaped stirring blade 71 is in close contact with the inner wall of the vertical part of the convex cylinder 1, so as to prevent part of the waste grease from coking in advance and reducing the quality and purity of the product. The horizontal part and the vertical part of the L-shaped stirring blade 71 are both trapezoidal structures, so as to facilitate using the inclined surfaces in the trapezoidal structures to scrape off the waste grease attached to the inner wall of the convex cylinder 1 and the top surface of the heating plate 8. An empty groove 63 is provided on the lower side inside the rotating rod 62. A turning assembly 72 is jointly provided between the inner side of the empty groove 63 and the vertical part of the L-shaped stirring blade 71;

[0033] In addition, during subsequent discharging, the L-shaped stirring blade 71 can also rotate to accelerate the departure of the residue after the pyrolysis of the waste grease, and at the same time reduce the residue, thereby reducing the subsequent cleaning steps, further reducing the working procedures, and improving the working efficiency.

[0034] Specifically, as Figure 5 and Figure 6 shown, in the middle of the upper end of the heating plate 8, there is a fixed rod 12. The upper end of the fixed rod 12 extends into the empty slot 63 and is provided with a first bevel gear 14;

[0035] Specifically, the flipping assembly 72 includes a transmission shaft 721 horizontally and rotatably connected to the vertical part of the L-shaped stirring blade 71. The outer surface of the transmission shaft 721 is evenly provided with three J-shaped flipping plates 722. The vertical cross-sectional shape of the J-shaped flipping plate 722 is J-shaped. One end of the transmission shaft 721 close to the rotating rod 62 extends to the inner side of the empty slot 63 and is provided with a second bevel gear 723, and the second bevel gear 723 meshes with the first bevel gear 14;

[0036] As can be seen from the above, when the rotating rod 62 controls the L-shaped stirring blade 71 and the flipping assembly 72 to rotate and stir the waste grease, the second bevel gear 723 also rolls on the first bevel gear 14 to drive the transmission shaft 721 to rotate self, so that the three J-shaped flipping plates 722 can continuously flip up and down, turning the part of the waste grease at the bottom to the upper part to improve the uniformity of the waste grease being heated.

[0037] Therefore, the specific implementation manner of the present utility model is as follows:

[0038] First, inject the waste grease into the convex cylinder 1 through the feed pipe, then start the heating plate 8 and the electric heating wire 10 to pyrolyze the waste grease. At the same time, start the motor 2, and control the rotating rod 62 to rotate through the polygonal shaft 61. Then the rotating rod 62 controls the L-shaped stirring blade 71 and the flipping assembly 72 to rotate and stir the waste grease. During this process, the second bevel gear 723 also rolls on the first bevel gear 14 to drive the transmission shaft 721 to rotate self, so that the three J-shaped flipping plates 722 can continuously flip up and down, turning the part of the waste grease at the bottom to the upper part to improve the uniformity of the waste grease being heated. After the pyrolysis is completed, the electric push rod 3 extends, and through the connecting plate 5, the rotating rod 62 and the heating plate 8 are moved downward, so that the residue after the pyrolysis of the waste grease on the heating plate 8 can fall into the bottom of the convex cylinder 1 through the gap between the heating plate 8 and the inner wall of the horizontal part of the convex cylinder 1. During this process, the solid residue will be intercepted by the filter screen frame 4 first and wait for subsequent treatment, while the liquid oil will directly leave through the discharge pipe.

[0039] It should be noted that the specific installation method, circuit connection method, and control method of the motor 2, the electric push rod 3, the heating plate 8, and the electric heating wire 10 in the present utility model are all conventional designs, and the present utility model will not be elaborated in detail.

Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments. What is described in the above-mentioned embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
