DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] Embodiment 1

[0030] like Figure 1-5As shown, a waste oil treatment and recovery device according to an embodiment of the utility model comprises: a housing 1, a latch structure 3 is installed at the front end of the housing 1, an inclined panel 5 is fixedly connected to the inside of the housing 1, a filter plate 7 is arranged between the inclined panels 5 on the inner wall of the housing 1, a self-locking mechanism 6 is installed inside the inclined panels 5 and the filter plate 7, and a sealing mechanism 8 is installed on the inner wall of the front end of the filter plate 7:

[0031] The self-locking mechanism 6 includes a connecting rod 61, and the connecting rods 61 are fixedly connected to both sides of the inner wall of the inclined panel 5, and the outer side of the connecting rod 61 is fixedly connected to a curved tube 62, and the outer side of the connecting rod 61 is slidably connected to a curved ring 63, and the curved ring 63 is located on the right side of the curved tube 62. The outer side of the connecting rod 61 is sleeved with a second spring 67, and the second spring 67 is located between the curved tube 62 and the curved ring 63. The inner wall of the rear end of the filter plate 7 is slidably connected to a sliding rod 64, and the outer diameter of the sliding rod 64 is provided with a first spring 65, and the top of the sliding rod 64 is fixedly connected to a slope block 66.

[0032] Specifically, before filtering the waste oil, the staff moves the filter plate 7 backward and embeds it into the groove of the shell 1. When the filter plate 7 slides backward to a certain distance, it contacts the curved cylinder 62 through the inclined surface block 66, and the inclined surface set by the curved cylinder 62 and the inclined surface set by the inclined surface block 66 are used to squeeze the inclined surface block 66 through the curved cylinder 62, so that the inclined surface block 66 drives the sliding rod 64 to slide downward inside the filter plate 7 and squeezes the first spring 65. When the filter plate 7 slides to a suitable distance again, the inclined surface block 66 is below the curved cylinder 62 and the curved ring 63. The elastic force of the squeezed first spring 65 drives the first spring 65 and the inclined surface block 66 to move upward and get stuck in the rear side of the curved cylinder 62. Thereby, the filter plate 7 is fixed, and the stability of the equipment when treating and filtering waste oil is improved. When the filter screen needs to be replaced or cleaned during use or in a stopped state of the equipment, the staff drives the filter plate 7 to move backward. When the filter plate 7 is moving, the inclined surface block 66 contacts the curved surface ring 63 with a smooth curved surface again and slides to the rear side of the curved surface ring 63, driving the filter plate 7 to move outward again, and the curved surface ring 63 is driven by the inclined surface block 66 to move into the groove of the curved surface cylinder 62, and the inclined surface of the rear side of the curved surface ring 63 is squeezed against the inclined surface block 66 again, so that the inclined surface block 66 moves to the front side of the curved surface cylinder 62, and then the filter plate 7 is unlocked, thereby realizing the rapid disassembly of the filter plate 7 for easy replacement or cleaning.

[0033] like Figure 3As shown, the latch structure 3 includes a fixed cylinder 31, the front end of the shell 1 is fixedly connected with the fixed cylinder 31, the inner wall of the fixed cylinder 31 is slidably connected with a latch plate 32, the middle part of the front end of the latch plate 32 is slidably connected with a latch rod 33, the bottom two sides of the latch plate 32 are fixedly connected with latch columns 34, the front end of the filter plate 7 is fixedly connected with a filter plate handle 35, and the top inner wall of the filter plate handle 35 is provided with a groove adapted to the outer diameter of the latch column 34.

[0034] Specifically, when the filter plate 7 is in normal use, the staff first contacts and drives the latch rod 33 to move forward, so that the latch rod 33 slides out of the through hole of the fixing cylinder 31, and then releases the limit on the latch rod 33, and then under the action of gravity, the latch plate 32 drives the latch column 34 to move downward, and the latch column 34 is inserted into the groove of the filter plate handle 35, and the latch rod 33 is pressed, and then the two ends of the filter plate 7 are limited, so that the forces on the two ends of the filter plate 7 are the same, preventing the middle part of the filter plate 7 from bending.

[0035] like Figure 5 As shown, the sealing mechanism 8 includes a third spring 81, and a plurality of third springs 81 are fixedly connected to the inner wall of the front end of the filter plate 7. The outer ends of the top ends of the third springs 81 are fixedly connected to curved blocks 82, and the outer walls of the curved blocks 82 are provided with sealing rings 83.

[0036] Specifically, when the filter plate 7 is installed, the elastic force of the third spring 81 inside the filter plate 7 drives the curved block 82 to expand outward, and then the curved block 82 drives the sealing ring 83 of the outer wall to expand outward, and the sealing ring 83 is embedded in the curved groove matched with the shell 1, thereby improving the sealing performance of the device.

[0037] like Figure 1 As shown, a feed port 2 is fixedly connected to the top of the shell 1 .

[0038] Specifically, the waste oil enters the housing 1 through the feed port 2, thereby filtering the waste oil.

[0039] like Figure 2 As shown, the inner wall of the shell 1 is located on the top of the inclined plate 5 and is fixedly connected with a guide plate 4.

[0040] Specifically, the guide plate 4 disposed at the top of the inclined plate 5 can prevent the waste oil from dripping onto the top of the top inclined plate 5 during the falling process when the waste oil enters the device through the feed port 2 .

[0041] like Figure 3 As shown, through holes having the same outer diameter as the latch rod 33 are provided at the upper and lower sides of the rear end of the fixing tube 31 .

[0042] Specifically, when the filter plate 7 is limited by the latch plate 32, the latch plate 32 and the latch column 34 are limited by the latch rod 33, which solves the problem of the latch column 34 being ejected due to the shaking of the machine.

[0043] like Figure 2 As shown, the outer walls at both ends of the curved block 82 are slidably connected to the front inner wall of the filter plate 7 .

[0044] Specifically, the curved surface block 82 slides on the inner wall of the filter plate 7, thereby driving the sealing ring 83 fixed on the outside to expand outward.

[0045] Working principle: First, the staff inserts the filter plate 7 into the groove of the housing 1. When the filter plate 7 slides backward to a certain distance, the inclined surface block 66 contacts the curved cylinder 62. Due to the curved surface of the curved cylinder 62 and the inclined surface of the inclined surface block 66, the inclined surface block 66 is squeezed by the curved cylinder 62, so that the inclined surface block 66 drives the sliding rod 64 to slide downward inside the filter plate 7 and squeezes the first spring 65. When the filter plate 7 slides to a suitable distance again, the elastic force of the squeezed first spring 65 drives the first spring 65 and the inclined surface block 66 to move upward and snap into the rear side of the curved cylinder 62, thereby fixing the filter plate 7 and completing the installation. The oil is poured into the interior of the waste oil treatment device through the feed port 2. After the waste oil is filtered by the filter plate 7, when the filter plate 7 needs to be cleaned, the filter plate 7 is driven to move backward. When the filter plate 7 is moving, the inclined surface block 66 contacts the curved surface ring 63 with a smooth curved surface again and slides to the rear side of the curved surface ring 63, driving the filter plate 7 to move outward again. The curved surface ring 63 is driven by the inclined surface block 66 to move into the groove of the curved surface cylinder 62, and the inclined surface of the rear side of the curved surface ring 63 is squeezed again, so that the inclined surface block 66 moves to the front side of the curved surface cylinder 62, and then the filter plate 7 is unlocked, thereby realizing the rapid disassembly of the filter plate 7 for easy replacement or cleaning.
