[0027] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0028] One preferred embodiment of the present application is shown in Figures 1 to 8 An oil mist recovery absorption tower heat tracing system, comprising an absorption tower body 1, a heating assembly 3, a stirring assembly 6, and a driving mechanism 5, the heating assembly 3 is installed inside the lower end of the absorption tower body 1, the stirring assembly 6 is movably arranged at the lower end of the side of the absorption tower body 1, and the driving mechanism 5 is installed on the side of the absorption tower body 1 and connected and matched with the stirring assembly 6.

[0029] It can be understood that when the oil in the absorption tower body 1 is condensed in winter, the heating assembly 3 and the driving mechanism 5 are started, the heating assembly 3 can melt the oil, and the driving mechanism 5 can drive the stirring assembly 6 to stir and mix the oil, thereby accelerating the melting process of the oil. After heating is completed, the driving mechanism 5 can retract the stirring assembly 6 at the side of the absorption tower body 1, which reduces the occupied space in the absorption tower body 1 and protects the stirring assembly 6 to improve the service life.

[0030] In one embodiment of the present application, as shown in Figure 3 and Figure 4 , the lower end of the side of the absorption tower body 1 is connected and mounted with the shell 2, the stirring assembly 6 is movably arranged in the shell 2, the driving mechanism 5 includes a moving device 8 and a driving device 7, the moving device 8 is mounted in the shell 2 and connected with the stirring assembly 6, and the driving device 7 is mounted in the shell 2 and has a one-way transmission connection with the stirring assembly 6 and the moving device 8.

[0031] It can be understood that when the driving device 7 performs the first action, the driving device 7 can drive the stirring assembly 6 to act, thereby stirring the oil in the absorption tower body 1. When the driving device 7 performs the second action, the driving device 7 can drive the moving device 8 to extend or retract the stirring assembly 6 into the shell 2. It should be understood that when the stirring assembly 6 extends out of the shell 2, it enters the absorption tower body 1, and when the stirring assembly 6 retracts into the shell 2, it separates from the absorption tower body 1.

[0032] Further, in order to prevent the oil in the absorption tower body 1 from flowing back into the shell 2, as shown in Figure 7 and Figure 8 , the shell 2 can be installed upwardly inclined, and the mounting point of the shell 2 is located above the oil level, so that under the action of gravity, the oil will not be stored in the shell 2.

[0033] Further description of the above embodiment: as shown in Figure 4 , the moving device 8 includes a reciprocating screw rod 801 and a sliding block 802, the reciprocating screw rod 801 is rotatably mounted in the shell 2 and has an end connected with the driving device 7, the sliding block 802 is slidably arranged in the shell 2 and connected with the stirring assembly 6, and the sliding block 802 cooperates with the reciprocating screw rod 801. It can be understood that when the driving device 7 performs the second action, the reciprocating screw rod 801 is driven to rotate, the reciprocating screw rod 801 acts on the sliding block 802, thereby driving the sliding block 802 to move the stirring assembly 6 to extend or retract the stirring assembly 6.

[0034] As shown in Figure 5 and Figure 6As shown, the stirring assembly 6 comprises a stirring shaft 601, stirring blades 603 and a sleeve 602, the stirring shaft 601 is rotatably installed on the sliding block 802 and the bottom end is installed with the stirring blades 603, the sleeve 602 is rotatably installed outside the shell 2 and connected with the driving device 7, the sleeve 602 is sleeved outside the stirring shaft 601 and connected with the stirring shaft 601 through the spline, that is, the stirring shaft 601 can be axially adjusted relative to the sleeve 602 under the action of the spline, and the sleeve 602 can drive the stirring shaft 601 to rotate under the action of the spline. Therefore, it can be understood that the driving device 7 can drive the sleeve 602 to rotate through the first action, and the sleeve 602 can drive the stirring shaft 601 to rotate to perform the stirring mixing operation.

[0035] In this embodiment, as shown in Figure 5 and Figure 6 The driving device 7 comprises a motor 701, a first transmission assembly 702 and a second transmission assembly 703, the motor 701 is installed outside the shell 2, the input ends of the first transmission assembly 702 and the second transmission assembly 703 are one-way transmission connected with the output end of the motor 701, and the output ends of the first transmission assembly 702 and the second transmission assembly 703 are connected with the sleeve 602 and the reciprocating screw rod 801 respectively.

[0036] It can be understood that when the first action is performed, we can set the forward rotation of the motor 701, the motor 701 can drive the stirring shaft 601 to rotate through the first transmission assembly 702, and at this time the second transmission assembly 703 is in disengaged state. Similarly, when the second action is performed, that is, the reverse rotation of the motor 701, the motor 701 can drive the reciprocating screw rod 801 to rotate through the second transmission assembly 703, and at this time the first transmission assembly 702 is in disengaged state.

[0037] As a further description of the above embodiment, the specific structure of the first transmission assembly 702 and the second transmission assembly 703 is not limited in this application, and a specific embodiment is provided below for reference:

[0038] The first transmission assembly 702 comprises a pulley one 7021, a pulley two 7022 and a synchronous belt one 7023, the pulley one 7021 is sleeved and installed on the sleeve 602, the pulley two 7022 is installed on the output end of the motor 701 through the one-way bearing 10, and the synchronous belt one 7023 is sleeved and installed on the pulley one 7021 and the pulley two 7022. The second transmission assembly 703 comprises a pulley three 7031, a pulley four 7032 and a synchronous belt two 7033, the pulley three 7031 is sleeved and installed on the reciprocating screw rod 801, and the pulley four 7032 is installed on the output end of the motor 701 through the one-way bearing 10.

[0039] It can be understood that when the motor 701 is rotating in the first action, the one-way bearing 10 on the pulley two 7022 is in the biting state, and then through the cooperation between the synchronous belt one 7023 and the pulley one 7021, the sleeve 602 and the stirring shaft 601 can be driven to rotate. At this time, the one-way bearing 10 on the pulley four 7032 is in the free state, that is, the second transmission assembly 703 is in the disengaged state, so that the reciprocating lead screw 801 remains stationary.

[0040] When the motor 701 performs the second action, the one-way bearing 10 on the pulley four 7032 is in the biting state, and then through the cooperation between the synchronous belt two 7033 and the pulley three 7031, the reciprocating lead screw 801 can be driven to rotate. At this time, the one-way bearing 10 on the pulley two 7022 is in the free state, that is, the first transmission assembly 702 is in the disengaged state, so that the stirring shaft 601 remains stationary.

[0041] It should be known that since the shell 2 is connected and installed on the side of the absorption tower body 1, when the stirring assembly 6 is not used and is retracted in the shell 2, at this time the oil mist in the absorption tower body 1 will also enter the shell 2, thereby affecting the parts in the shell 2.

[0042] Therefore, in order to solve the above technical problems, in one embodiment of the present application, as shown in Figure 4 The bottom end of the stirring shaft 601 extends and rotates to install a piston 9. It can be understood that when the stirring assembly 6 is retracted and rises, after the stirring assembly 6 rises to the limit position, at this time the piston 9 just blocks at the bottom end of the shell 2, and at this time the piston 9 and the inner side of the absorption tower body 1 are tangent, that is, the piston 9 does not protrude from the inner side of the absorption tower body 1, and it just fits the missing part of the inner side of the absorption tower body 1, as shown in Figure 7 .

[0043] Specifically, as shown in Figure 4 When the stirring assembly 6 is retracted, the piston 9 can form a sealed cavity between the inside of the shell 2, thereby isolating the stirring assembly 6 from the tower body, and an oil outlet 4 is provided at the lower end of the outside of the shell 2, which is in communication with the sealed cavity. The oil outlet 4 includes an oil outlet pipe and an end cap, the oil outlet pipe is in communication with the sealed cavity, and the end cap can be threadedly connected to the bottom end of the oil outlet pipe.

[0044] Understandably, when the stirring assembly 6 extends into the absorption tower body 1, oil will adhere to the stirring shaft 601, stirring blades 603, and piston 9. When the stirring assembly 6 retracts into the shell 2, this adhered oil will be carried into the sealed cavity. Over time, the oil is prone to deterioration, thus affecting the internal environment of the shell 2. By providing the oil outlet 4, the internal oil will accumulate in the oil outlet pipe under gravity. Then, by opening the end cap, the internal oil can be discharged, effectively avoiding the deterioration problem caused by the long-term accumulation of oil in the sealed cavity. In addition, the oil outlet 4 can also serve as a cleaning port, i.e., cleaning can be performed by injecting cleaning fluid into the shell 2.

[0045] In this embodiment, as Figure 2 As shown, heating component 3 is a coil. During heating, a heat transfer medium (such as heat transfer oil or steam) is injected into the coil, and then the oil in the absorption tower 1 is indirectly heated through the coil. This can effectively solve the shutdown problem caused by the solidification of the wash oil, and also avoid the safety hazards caused by installing heat tracing (such as electric heating wire or electric heating plate).

[0046] The working principle of this utility model is as follows:

[0047] When it is necessary to melt the oil inside the tower, heat transfer oil can be introduced into the coil, thereby melting the oil inside the tower through heat transfer. To improve the uniformity and efficiency of oil heating, a stirring component 6 can be used to stir and mix the oil. Initially, the stirring component 6 is as follows... Figure 7 As shown, it contracts and is located inside the housing 2. First, the motor 701 is started to perform the second action (reverse rotation), which then drives the reciprocating screw 801 to rotate through the second transmission assembly 703. The reciprocating screw 801 acts on the slider 802, which in turn causes the slider 802 to drive the stirring assembly 6 to move downward to its limit position, as shown. Figure 8 As shown. At this time, the motor 701 performs the first action (forward rotation), which in turn drives the stirring shaft 601 to rotate through the first transmission component 702. The stirring blades 603 then mix and stir the oil, achieving rapid heating and melting of the oil. Finally, the stirring component 6 retracts, that is, the motor 701 is restarted in reverse, and under the action of the reciprocating screw 801, the stirring component 6 moves upward into the housing 2, so that the stirring component 6 returns to its initial state.

[0048] The foregoing describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments, and the above-described embodiments and descriptions in the specification are only the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
