At this time, the crude oil will flow downward due to its own gravity and pass through the No. 1 filter 6 and the No. 2 filter 7 in sequence, thereby facilitating the filtering of impurities in the crude oil.

[0021] The rotating tube 8 is movably sleeved in the middle of the top cover 2, and the rotating tube 8 is made of metal material. The rotating tube 8 is movably sleeved in the middle of the No. 1 filter screen 6 and the No. 2 filter screen 7. A driving assembly 9 is arranged outside the top of the rotating tube 8. The driving assembly 9 includes a driving motor 91. The driving motor 91 is fixedly mounted on the top of the top cover 2, and a driving gear 92 is fixedly sleeved on the output shaft of the driving motor 91. The driving gear 92 is meshed and connected with a driven gear 93 on the outside. The driven gear 93 is fixedly sleeved on the outside of the top of the rotating tube 8, and a branch pipe 12 is fixedly connected to the side of the rotating tube 8; In this embodiment, during the process of heating and filtering crude oil, the driving motor 91 is turned on to rotate the driving gear 92, and the driving gear 92 drives the driven gear 93 to rotate, and the driven gear 93 drives the rotating tube 8 to rotate, so that the rotating tube 8 drives the branch pipe 12 to rotate, and the branch pipe 12 is used to drive the fluidity of the crude oil on the top of the No. 1 filter screen 6 and the No. 2 filter screen 7, which can speed up the filtering speed of the crude oil, thereby improving the working efficiency of crude oil filtration.

[0022] A steam inlet pipe 10 and a steam extraction pipe 11 are provided at the top of the rotating tube 8, a branch pipe 12 is fixedly connected to the side of the rotating tube 8, a telescopic rod 13 is fixedly connected to the bottom of the branch pipe 12, a collision block 14 is fixedly connected to the bottom of the telescopic rod 13, a steam inlet valve and a steam extraction valve are fixedly installed on the outside of the steam inlet pipe 10 and the steam extraction pipe 11, and one end of the steam inlet pipe 10 and the steam extraction pipe 11 is movably connected to the top of the rotating tube 8 through a connecting pipe, the branch pipe 12 is made of metal material, and the telescopic rod 13 is made of elastic material, a drain pipe 15 is fixedly connected to the bottom of the furnace body 1, and a drain valve is fixedly installed on the outside of the drain pipe 15; In this embodiment, during the rotation of the rotary tube 8, the steam inlet valve is opened so that high-temperature steam can flow into the interior of the rotary tube 8 along the steam inlet pipe 10, and the high-temperature steam will flow inside the rotary tube 8 and the branch pipe 12, so that the surface temperature of the rotary tube 8 and the branch pipe 12 can be increased, and the heat can be transferred to the crude oil liquid to heat the crude oil liquid, thereby avoiding the problem of solidification of the crude oil liquid, and thus increasing the fluidity of the crude oil liquid; At the same time, during the high-temperature steam input process, the high-temperature steam will enter the interior of the telescopic rod 13 along the branch pipe 12, causing the telescopic rod 13 to extend due to the increase in internal pressure, and the telescopic rod 13 will drive the impact block 14 to move vertically downward, so that the impact block 14 and the first filter 6 (or the second filter 7) are in contact, and then the steam inlet valve is closed, the steam extraction valve is opened, and the steam inside the rotating tube 8 and the branch pipe 12 is extracted by the steam extraction pipe 11. At this time, the telescopic rod 13 retracts due to the reduction in internal pressure, and the telescopic rod 13 will drive the impact block 14 to move vertically upward, so that the impact block 14 is in contact with the first filter 6 (or the second filter 7). The first filter screen 6 (or the second filter screen 7) is separated from the first filter screen 6 (or the second filter screen 7). By continuously repeating the above operation, the high-temperature steam is continuously input and extracted, which can prompt the impact block 14 to continuously impact the first filter screen 6 (or the second filter screen 7), so that the impurities blocked in the first filter screen 6 (or the second filter screen 7) can be impacted out, avoiding the problem of blockage of the first filter screen 6 (or the second filter screen 7), so that the crude oil can smoothly pass through the first filter screen 6 (or the second filter screen 7), indirectly accelerating the filtering speed of the crude oil, thereby further improving the work efficiency.

[0023] In summary, compared with most existing filtering devices, the energy-saving and environmentally friendly crude oil heating furnace of this embodiment has the following advantages: 1. By providing the rotating tube 8, the driving assembly 9 and the branch pipe 12, the fluidity of the crude oil at the top of the No. 1 filter screen 6 or the No. 2 filter screen 7 can be increased during the crude oil filtration process, thereby avoiding the problem that the impurities are blocked from flowing due to static accumulation, thereby accelerating the filtration speed of the crude oil, thereby improving the working efficiency of the crude oil filtration; 2. By providing the steam inlet pipe 10 and the steam extraction pipe 11, the high-temperature steam can flow inside the rotating tube 8 and the branch pipe 12, causing the temperature of the surface of the rotating tube 8 and the branch pipe 12 to rise, and transferring the heat to the crude oil liquid to heat the crude oil liquid, thereby avoiding the problem of solidification of the crude oil liquid, thereby increasing the fluidity of the crude oil liquid. At the same time, by continuously inputting and extracting the high-temperature steam, the impact block 14 can continuously impact the No. 1 filter screen 6 (or the No. 2 filter screen 7), so that the impurities blocked in the No. 1 filter screen 6 (or the No. 2 filter screen 7) can be impacted out, avoiding the problem of blockage of the No. 1 filter screen 6 (or the No. 2 filter screen 7), allowing the crude oil liquid to smoothly pass through the No. 1 filter screen 6 (or the No. 2 filter screen 7), indirectly accelerating the filtering speed of the crude oil liquid, thereby further improving the work efficiency.

[0024] Embodiment 2 See also Figure 5 and Figure 6The energy-saving and environmentally friendly crude oil heating furnace of this embodiment is added with a lifting assembly 16 on the basis of the first embodiment. The lifting assembly 16 includes a horizontal plate 161, which is fixedly connected to one side of the top cover 2, and the bottom of the horizontal plate 161 is fixedly connected with an electric push rod 162, and the outside of the electric push rod 162 is fixedly connected to the side of the furnace body 1 through a mounting plate 163, one side of the horizontal plate 161 and one side of the top cover 2 are perpendicular to each other, and the bottom of the horizontal plate 161 and the top of the electric push rod 162 are perpendicular to each other; In this embodiment, when the crude oil filtering is completed and the impurities on the No. 1 filter 6 and the No. 2 filter 7 need to be cleaned, the electric push rod 162 is started to extend, and the electric push rod 162 will use the cross plate 161 to drive the top cover 2 to move vertically upward, so that the top cover 2 and the furnace body 1 are separated, and the No. 1 filter 6 and the No. 2 filter 7 can be moved out from the inside of the furnace body 1, so that the impurities adhered to the surface of the No. 1 filter 6 and the No. 2 filter 7 can be cleaned, thereby bringing convenience to the use of the filtering device.

[0025] In summary, the energy-saving and environmentally friendly crude oil heating furnace of the present embodiment, by providing a lifting assembly 16, can facilitate the removal of the No. 1 filter 6 and the No. 2 filter 7 from the interior of the furnace body 1 after the crude oil filtering is completed, so that the impurities adhered to the surface of the No. 1 filter 6 and the No. 2 filter 7 can be cleaned, thereby bringing convenience to the use of the filtering device.

[0026] Embodiment 3 See also Figure 7-9 The energy-saving and environmentally friendly crude oil heating furnace of this embodiment adds an intelligent control component on the basis of the second embodiment. The intelligent control component includes a liquid level sensing probe 17 and a controller 18. The liquid level sensing probe 17 is fixedly installed at the bottom of the top cover 2, and the output end of the liquid level sensing probe 17 is signal-connected to the input end of the controller 18. The controller 18 includes a signal receiving module 181, a signal processing module 182 and an instruction transmission module 183. The input of the signal receiving module 181 is signal-connected to the output end of the liquid level sensing probe 17, and the output end of the signal receiving module 181 is signal-connected to the input end of the signal processing module 182, the output end of the signal processing module 182 is signal-connected to the input end of the instruction transmission module 183, and the output end of the instruction transmission module 183 is electrically connected to the input end of the liquid inlet valve 4; In this embodiment, when the crude oil is being filtered, the liquid level sensing probe 17 will monitor the amount of crude oil above the No. 1 filter 6 in real time, and transmit the liquid level information of the crude oil to the signal receiving module 181 in the form of a signal, and the signal receiving module 181 will transmit the received signal to the signal processing module 182, at which time the signal processing module 182 will analyze and process the signal. If the liquid level of the crude oil is high, the instruction transmission module 183 will disconnect the circuit of the liquid inlet valve 4, so that the liquid inlet valve 4 is closed, thereby stopping the delivery of crude oil; If the liquid level of the crude oil is low, the instruction transmission module 183 will connect the circuit of the liquid inlet valve 4, so that the liquid inlet valve 4 opens, prompting the crude oil to be continuously transported to the inside of the furnace body 1, and as the crude oil in the liquid inlet pipe 3 is replenished, the liquid level of the crude oil in the furnace body 1 will gradually increase, which is convenient for precise control of the amount of oil filtered in the furnace body 1, thereby reflecting the intelligence of the filtering device.

[0027] In summary, the energy-saving and environmentally friendly crude oil heating furnace of this embodiment, by providing a liquid level sensing probe 17, a controller 18 and a liquid inlet valve 4, can facilitate real-time monitoring of the amount of crude oil above the No. 1 filter 6 during the crude oil filtration process, and can accurately control the amount of oil filtered in the furnace body 1, thereby reflecting the intelligence of the filtration device.

[0028] In the above scheme, it should be noted that: the interior of the rotating tube 8 is hollow, and the bottom end of the rotating tube 8 is sealed, the rotating tube 8, the branch tube 12 and the telescopic rod 13 are interconnected, and the telescopic rod 13 is composed of a sleeve, a movable rod and a piston (refer to the attached manual Figure 4 ), the movable rod is movably sleeved inside the sleeve, and the top of the sleeve is fixedly connected to the bottom of the branch pipe 12, the bottom of the movable rod is fixedly connected to the top of the impact block 14, the top of the movable rod is fixedly connected to a piston, and the piston is movably sleeved inside the sleeve; The steam inlet valve and steam extraction valve outside the steam inlet pipe 10 and the steam extraction pipe 11 are connected to an external control unit, and the control unit can be used to intelligently control the opening and closing of the steam inlet valve and the steam extraction valve (the control principle of the control unit is an existing public technology and will not be described in detail here). In this way, frequent switching of steam intake and steam extraction operations can be achieved. At the same time, since the flow channel inside the rotating tube 8 is unidirectional, the heat energy of the steam will be lost in the process of heat transfer, and continuous steam extraction and intake into the rotating tube 8 can not only ensure the stable heating effect of the crude oil, but also drive the impact block 14 to impact the filter.

[0029] The working principle and use process of the present invention are as follows: first, the liquid inlet valve 4 is opened, so that the crude oil to be filtered during oil refining production flows into the interior of the furnace body 1 along the liquid inlet pipe 3. At this time, the crude oil will flow downward due to its own gravity, and pass through the No. 1 filter 6 and the No. 2 filter 7 in sequence. At the same time, the driving motor 91 is turned on to rotate the driving gear 92, and the driving gear 92 drives the driven gear 93 to rotate, and the driven gear 93 drives the rotating tube 8 to rotate, so that the rotating tube 8 drives the branch pipe 12 to rotate, and the branch pipe 12 is used to accelerate the fluidity of the crude oil at the top of the No. 1 filter 6 and the No. 2 filter 7, so that the filtering speed of the crude oil can be accelerated; Then, the steam inlet valve is opened, so that the high-temperature steam can flow into the interior of the rotary tube 8 along the steam inlet pipe 10, and the high-temperature steam will flow inside the rotary tube 8 and the branch pipe 12, so that the temperature of the surface of the rotary tube 8 and the branch pipe 12 can be increased, and the heat can be transferred to the crude oil liquid to heat the crude oil liquid, thereby avoiding the problem of solidification of the crude oil liquid, thereby increasing the fluidity of the crude oil liquid, and at the same time, through the continuous input and extraction of high-temperature steam, the impact block 14 can continuously impact the No. 1 filter screen 6 (or No. 2 filter screen 7), so that the impurities blocked in the No. 1 filter screen 6 (or No. 2 filter screen 7) can be impacted out, so that the crude oil liquid can smoothly pass through the No. 1 filter screen 6 (or No. 2 filter screen 7), indirectly accelerating the filtering speed of the crude oil liquid, thereby improving the working efficiency of crude oil filtration; Then, when the crude oil is being filtered, the liquid level sensor probe 17 monitors the amount of crude oil above the No. 1 filter 6 in real time, and transmits the liquid level information of the crude oil to the controller 18 in the form of a signal, and then uses the controller 18 to control the opening or closing state of the liquid inlet valve 4, and replenishes or stops the delivery of the crude oil on the top of the No. 1 filter 6 in time, so that the amount of oil filtered in the furnace body 1 can be accurately controlled, thereby reflecting the intelligence of the filtering device; Finally, when the crude oil filtering is completed, the electric push rod 162 is started to extend, and the electric push rod 162 will use the cross plate 161 to drive the top cover 2 to move vertically upward, so that the top cover 2 and the furnace body 1 are separated, and the No. 1 filter 6 and the No. 2 filter 7 can be moved out from the inside of the furnace body 1, so that the impurities adhered to the surface of the No. 1 filter 6 and the No. 2 filter 7 can be cleaned, thereby bringing convenience to the use of the filtering device.
