Description

TECHNICAL FIELD

[0001] The application relates to the technical field of petroleum refining sludge treatment, and particularly relates to a petroleum refining sludge ultrasonic cracking and reduction treatment device. BACKGROUND

[0002] In the process of petroleum refining sludge treatment, the ultrasonic wave can break the structure of the organic matter in the sludge, so that the sludge is more easily decomposed, thereby improving the reduction effect of the sludge, and the ultrasonic wave can improve the dissolved oxygen content in the sludge, accelerate the biological degradation process, reduce the volume of the sludge, and improve the disposal effect.

[0003] Although the traditional ultrasonic treatment device combines the use of a stirrer and an ultrasonic vibrator to improve the cracking efficiency of the sludge and the energy utilization efficiency, the ultrasonic vibrator is mostly directly and fixedly arranged in the treatment device, and when the ultrasonic vibrator is fixed, the propagation path of the ultrasonic wave beam generated by the ultrasonic vibrator in the sludge is relatively fixed, which can easily cause the ultrasonic energy to be mainly concentrated near the vibrator, and the energy is low far away from the vibrator, and especially when the sludge has a large volume or a high viscosity, the uneven distribution of the energy can cause part of the sludge to be not fully cracked, thereby affecting the cracking efficiency and the energy utilization efficiency.

[0004] Therefore, the application provides a petroleum refining sludge ultrasonic cracking and reduction treatment device to solve the above problems. CONTENT OF THE INVENTION

Through the cooperation of the connecting gear, the transmission gear, the transmission shaft, the runner and the eccentric shaft, the transmission of the power of the stirrer to the connecting pipe can be realized, so that the ultrasonic vibrator can lift and drop with the rotation of the stirrer, thereby enhancing the contact effect of the sludge and the ultrasonic wave.

[0030] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0031] Example 1

[0032] The present embodiment provides a kind of petroleum refining sludge ultrasonic cracking reduction processing device, as shown in Figure 1 And Figure 2As shown, the processing device comprises a base 1, a processing tank 2 fixedly arranged on the base 1, an agitator 3 rotatably arranged in the processing tank 2, an ultrasonic vibrator 4 arranged at a side of the processing tank 2 corresponding to the agitator 3, an ultrasonic generator arranged outside the processing tank 2 and electrically connected with the ultrasonic vibrator 4 through a wire, and a screw conveyor 5 arranged at a side of the bottom of the processing tank 2 and used for discharging sludge; the processing device further comprises a limiting plate 6 fixedly arranged inside the processing tank 2 and located at a position above the ultrasonic vibrator 4, a connecting pipe 7 slidably connected with the limiting plate 6 and fixedly connected with the top end of the ultrasonic vibrator 4 and used for sleeving outside the wire of the ultrasonic vibrator 4, and a transmission assembly 8 connected with the agitator 3 and the connecting pipe 7 and used for transmitting the rotating power of the agitator 3 to the connecting pipe 7 so as to make the ultrasonic vibrator 4 reciprocatingly lift and drop.

[0033] It should be noted that the screw conveyor 5 is a prior art device which pushes materials to realize conveying through the rotating helical blade, and the screw conveyor 5 is arranged at a side of the bottom of the processing tank 2 so as to discharge the sludge after the sludge is cracked by ultrasonic waves.

[0034] In use, the sludge to be processed is put into the processing tank 2, and the motor 35 and the ultrasonic generator are started to stir and crack the sludge, wherein the ultrasonic generator provides electric energy to the ultrasonic vibrator 4 through the wire, and then the ultrasonic vibrator 4 generates ultrasonic waves under the drive of the electric energy, the ultrasonic waves further crush the cell wall so as to realize the dissolution of the microbial cells, thereby realizing the cracking of the sludge, however, since the transmission assembly 8 and the connecting pipe 7 are connected and used, when the agitator 3 rotates and stirs in the processing tank 2, the transmission assembly 8 transmits the power to the connecting pipe 7 synchronously, and drives the connecting pipe 7 to reciprocatingly lift and drop on the limiting plate 6, since the ultrasonic vibrator 4 is connected with the connecting pipe 7, the ultrasonic vibrator 4 can reciprocatingly lift and drop in the stirring process, thereby making the ultrasonic waves more uniformly act on the sludge, and enhancing the cracking effect, when the sludge is cracked by ultrasonic waves, the screw conveyor 5 is started to discharge the sludge at the bottom of the processing tank 2 through the screw conveyor 5.

[0035] Specifically, the agitator 3 comprises a fixing frame 31 fixedly arranged on the base 1 and located at the top end of the processing tank 2, an agitating shaft 32 arranged in the processing tank 2 and rotatably connected with the fixing frame 31, agitating blades 33 arranged in the processing tank 2 and fixedly connected with the agitating shaft 32, a box body 34 fixedly arranged on the fixing frame 31 and sleeved outside the agitating shaft 32, and a motor 35 fixedly arranged on the box body 34 and used for driving the agitating shaft 32 to rotate.

[0036] When the sludge needs to be stirred, the motor 35 is started, and the stirring shaft 32 starts to rotate under the driving of the motor 35. With the rotation of the stirring shaft 32, the stirring blade 33 will rotate in the treatment tank 2. Then, with the rotation of the stirring blade 33, centrifugal force, shear force and collision force will be generated, so that the sludge can be rapidly dispersed, sheared, collided and mixed.

[0037] Further, the transmission assembly 8 comprises a connecting gear 81 arranged in the box body 34 and fixedly sleeved on the stirring shaft 32, a transmission shaft 83 transversely penetrating through the box body 34 and rotationally connected to one side of the box body 34 corresponding to the connecting gear 81, a transmission gear 82 fixedly sleeved on the transmission shaft 83 close to one end of the box body 34 and engaged with the connecting gear 81, a rotating wheel 84 fixedly connected to one end of the transmission shaft 83 away from the transmission gear 82, an eccentric shaft 85 fixedly connected to the rotating wheel 84, and a connecting rod 86 rotationally connected to the eccentric shaft 85 and the top end of the connecting pipe 7 at two ends respectively.

[0038] When the motor 35 is started to drive the stirring shaft 32 to stir the sludge in the stirring blade 33 in the treatment tank 2, the connecting gear 81 connected to the stirring shaft 32 will also rotate synchronously. Since the connecting gear 81 is engaged with the transmission gear 82, with the rotation of the connecting gear 81, the transmission gear 82 will transmit the rotating power to the transmission shaft 83. Then, the transmission shaft 83 will rotate synchronously with the rotating wheel 84. The rotation of the rotating wheel 84 will further drive the eccentric shaft 85 to produce eccentric motion. At this time, the eccentric motion of the eccentric shaft 85 will be transmitted to the connecting pipe 7 through the connecting rod 86. Since the two ends of the connecting rod 86 are rotationally connected to the eccentric shaft 85 and the connecting pipe 7 respectively, the eccentric motion of the eccentric shaft 85 is converted into the reciprocating lifting motion of the connecting pipe 7 on the limiting plate 6. Therefore, the reciprocating lifting motion of the connecting pipe 7 will drive the ultrasonic vibrator 4 to move up and down in the treatment tank 2. This up and down movement can enhance the cracking effect of ultrasonic waves, so that the sludge can be treated more uniformly.

[0039] In order to ensure the use of the rotating wheel 84 and the connecting rod 86, the fixed frame 31 is provided with a through groove 311 for the free movement of the rotating wheel 84 and the connecting rod 86 at the positions corresponding to the rotating wheel 84 and the connecting rod 86. The design of the through groove 311 allows the rotating wheel 84 and the connecting rod 86 to freely move on the fixed frame 31, ensuring the normal operation of the transmission assembly 8 and avoiding the interference of the fixed frame 31 with the transmission assembly 8.

[0040] Example 2

[0041] Different from example 1, as shown in FIG. 2, the transmission assembly 8 of the sludge treatment device 1 comprises a fixed frame 31, a stirring shaft 32, a stirring blade 33, a motor 35, a connecting gear 81, a transmission shaft 83, a transmission gear 82, a rotating wheel 84, an eccentric shaft 85 and a connecting rod 86. Figure 3 and Figure 4As shown, in order to ensure the use and protection of the connecting pipe 7 and the ultrasonic vibrator 4, the bottom end of the limiting plate 6 is provided with a dirt cleaning piece 9 for cleaning the surface dirt of the connecting pipe 7, the dirt cleaning piece 9 comprises a mounting plate 91 fixedly arranged at the bottom of the limiting plate 6 and a rubber ring 92 fixedly arranged at the side of the mounting plate 91 away from the limiting plate 6 and in contact with the surface of the connecting pipe 7, and the connecting pipe 7 penetrates the limiting plate 6, the mounting plate 91 and the rubber ring 92 in sequence;

[0042] By arranging the rubber ring 92 on the mounting plate 91, the connecting pipe 7 can contact the rubber ring 92 when passing through the rubber ring 92 during lifting, so that the rubber ring 92 can wipe off the dirt on the surface of the connecting pipe 7, and the design of the rubber ring 92 can also prevent the top end of the ultrasonic vibrator 4 from directly contacting the mounting plate 91 during lifting with the connecting pipe 7, thereby protecting the ultrasonic vibrator 4.

[0043] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
