Description

Technical Field

[0001] The invention relates to the technical field of heat recovery equipment, and more specifically, to a heat recovery equipment for waste oil distillation. Background Art

[0002] Waste oil refers to oil that is purified from crude oil or synthesized and contaminated by physical or chemical impurities after use. Simply put, waste oil, as its name suggests, is oil that comes from petroleum or synthetic oil and has been used. Waste oil can be recycled during the waste oil treatment process, so it can be recycled through waste oil distillation equipment.

[0003] According to a heat-recoverable evaporation device for distillation proposed in Patent No. CN218686400U, the steam generated during the distillation process of the evaporation device body enters the shell-and-tube heat exchanger through the first steam delivery pipe. At this time, the first control valve is opened, and the water inside the water tank enters the shell-and-tube heat exchanger to complete heat exchange with the high-temperature steam. The temperature of the water inside the shell-and-tube heat exchanger gradually rises, and finally the delivery pump is started. The delivery pump delivers the water heated by the high-temperature steam to the water storage cavity between the heat-insulating outer layer and the evaporation device body. On the one hand, it is used to improve the heat-insulating effect of the heat-insulating outer layer on the evaporation device body, and on the other hand, the water temperature can be conducted to the inside of the evaporation device body to improve the distillation efficiency.

[0004] However, the equipment still has some shortcomings when in use. When the equipment is used for a long time, the steam inside the equipment will cling to the inner wall. If the equipment is not cleaned in time, steam drying will produce scale, which will affect the use of the equipment.

[0005] Therefore, it is necessary to provide a waste oil distillation heat recovery device to solve the above problems. Utility Model Content

[0006] Based on the above problems existing in the prior art, the purpose of the embodiments of the present application is to provide a heat recovery device for waste oil distillation.

[0007] The technical solution adopted by the present application to solve its technical problems is: a heat recovery device for waste oil distillation, including a supporting base plate and a distillation component, the distillation component including an outer sleeve fixedly connected to the top of the supporting base plate, the inner wall of the outer sleeve is fixedly connected with a fixing strip, the fixing strip is fixedly connected with an inner sleeve on the side away from the outer sleeve, the inner sleeve is installed in the inner part of the outer sleeve through the outer side of the fixing strip, a water outlet valve is installed at the bottom of the inner sleeve, a plurality of water inlets are provided on the outer side of the inner sleeve, a fixing ring is fixedly connected to the outer side of the inner sleeve near the water inlet, a plurality of sockets are provided on the top of the outer sleeve, and the same number of positioning strips are inserted into the inside of the sockets.

[0008] Furthermore, a handle is fixedly connected to the top of the positioning strip, and the positioning strips respectively pass through the same number of insertion holes and contact the outer side of the water inlet.

[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0020] In the present invention, unless otherwise specified, directions such as "up" and "down" are usually relative to the directions shown in the drawings, or relative to the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "left" and "right" are usually relative to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0021] like Figure 1-4 As shown, the present application provides a heat recovery device for waste oil distillation. It includes a supporting bottom plate 1 and a distillation assembly 2, wherein the distillation assembly 2 includes an outer sleeve 201 fixedly connected to the top of the supporting bottom plate 1, a fixing strip 202 fixedly connected to the inner wall of the outer sleeve 201, an inner sleeve 203 fixedly connected to the side of the fixing strip 202 away from the outer sleeve 201, a plurality of water inlets 205 are provided on the outer side of the inner sleeve 203, a fixing ring 204 is fixedly connected to the outer side of the inner sleeve 203 near the water inlet 205, a plurality of plug holes 206 are provided on the top of the outer sleeve 201, and the same number of positioning strips 207 are inserted into the inner side of the plug holes 206.

[0022] A handle 208 is fixedly connected to the top of the positioning strip 207 , and the positioning strips 207 pass through the same number of insertion holes 206 and contact the outer side of the water inlet 205 .

[0023] The inner sleeve 203 is installed inside the outer sleeve 201 through the outer side of the fixing strip 202 , and a water outlet valve is installed at the bottom of the inner sleeve 203 .

[0024] A rotating motor 209 is fixedly connected to the top of the outer sleeve 201 , an input end of the rotating motor 209 is electrically connected to an external power source, and an output shaft of the rotating motor 209 is fixedly connected to a cleaning rod 210 .

[0025] The cleaning rod 210 is a frame-shaped structure, and the edges of the cleaning rod 210 are respectively in contact with the inner wall of the inner sleeve 203 .

[0026] When the device is in use, after the waste oil is continuously evaporated inside the device, the evaporated gas will continuously gather upward inside the inner sleeve 203, which is difficult to clean. If it is not cleaned in time, it will cause scale to form. At this time, the device can be used when it is working or stopped, and the rotating motor 209 will be turned on to drive the cleaning rod 210 to scrape the inner wall of the inner sleeve 203, so that the water accumulated on the inner wall of the inner sleeve 203 can be scraped off in time, so as to avoid the situation that scale will form on the inner wall of the inner sleeve 203. At the same time, when the cleaning rod 210 scrapes the inner wall of the inner sleeve 203, the water can be quickly concentrated, so that the water can be quickly collected, thereby improving the collection efficiency of the device;

[0027] Furthermore, after the equipment is finished working, the cleaning rod 210 can continue to run inside the inner sleeve 203, and the handle 208 can be held and pulled upward, thereby driving a plurality of positioning strips 207 to separate at the position of the water inlet 205, so that the water inlet 205 is exposed on one side of the fixing ring 204, and then the external water pipe is inserted into any one of the jacks 206, so that the water sprayed inside the external water pipe can enter the inner sleeve 203 through the water inlet 205, so that the water can hit the inner wall of the inner sleeve 203. The cleaning rod 210 is used to further improve the cleaning effect of the inner sleeve 203. After the cleaning is completed, the water inside can be discharged through the water outlet valve at the bottom of the inner sleeve 203. Finally, after the inner sleeve 203 is cleaned, the positioning strip 207 can be aligned with the position of the socket 206 for installation, so that the positioning strip 207 will contact the fixing ring 204 after installation, and the positioning strip 207 will re-seal the outer side of the water inlet 205, so as to improve the sealing performance of the equipment.
