Description

Technical Field

[0001] The invention belongs to the technical field of waste oil sludge treatment, and specifically refers to a continuous homogenizing device for waste oil sludge treatment. Background Art

[0002] At present, whether in the oil extraction industry or in the oil refining industry, a large amount of oily sludge is produced. These sludges are generally stored in a specific sludge pool for collection, and the collected sludge is regularly reduced. In the reduction treatment, the first thing to do is to add a demulsifier to the sludge for homogenization. Because the viscosity of the oil sludge itself is high, water will also be added to reduce the viscosity of the oil sludge and improve the effect of the demulsifier.

[0003] The same volume of oily sludge with different densities requires different amounts of demulsifiers, but the existing oily sludge homogenization equipment cannot automatically adjust the amount of demulsifier added to treat oily sludge of different concentrations, and even requires manual addition of demulsifiers, which greatly affects the treatment efficiency of oily sludge and easily causes waste of demulsifiers. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a continuous homogenizing device for treating waste oil sludge. Before the waste oil sludge enters the homogenizing tank from the feed pipe, it needs to pass through the weighing plate on the weighing trough. The waste oil sludge will press down the weighing plate. Since the weight and viscosity of waste oil sludge of different concentrations are different, the height to which the weighing plate descends is different. The dial plate feeds back the descending height of the weighing plate to the proportioning slider, pushing the proportioning slider to move, and then the water pipe adjusting hole on the proportioning slider changes the pore size between the water inlet pipe and the water inlet hole, thereby changing the water inlet amount and adjusting the density of the waste oil sludge. Similarly, the pore size between the additive adjusting hole and the additive pipe and the additive hole will also change with the change of the waste oil sludge density, thereby achieving the technical effect of automatically adjusting the amount of demulsifier added. Different types of waste oil sludge have different density ranges. By turning the adjusting knob to drive the spring adjusting column to rotate, the bottom of the weighing plate The spring adjustment plate moves up, thereby changing the elastic force of the weighing spring, thereby achieving the technical effect of adjusting the initial detection pressure of the weighing plate; the oil sludge and demulsifier are quickly mixed by the stirring shaft for homogenization, and at the same time, the stirring shaft bevel gear of the stirring shaft drives the rotating shaft to rotate, and the rotating shaft drives the auger blades to rotate slowly through the eccentric gear plate, and the auger blades transport the homogenized oil sludge to the auger tank, giving the homogenized oil sludge sufficient sedimentation time, so that under the control of the one-step motor, the oil sludge is stirred and homogenized at high speed in the homogenization tank, and slowly transported and precipitated in the auger tank, that is, the technical effect of continuous homogenization and sedimentation of the oil sludge is achieved, the floating liquid of the oil sludge flows out through the drain pipe of the separation tank, and the precipitated sludge is discharged through the discharge pipe; the internal tooth ratchet on the auger tank controls the eccentric gear plate to rotate only in one direction, preventing the eccentric gear plate from rotating with the rotating shaft under the action of friction, thereby effectively solving the above problems.

[0007] Preferably, the oil sludge and demulsifier are quickly mixed by stirring the stirring shaft, and the bottom blade of the stirring shaft is designed to be a blade with a low center and a high outside, which prevents the oil sludge from settling at the bottom while causing a speed difference between the center and the edge of the oil sludge to form a vortex, thereby promoting the demulsifier to quickly destroy the emulsion system in the sewage.

[0009] Preferably, before the oily sludge enters the homogenizing tank from the feed pipe, it needs to pass through the weighing plate on the weighing tank. The oily sludge will press down the weighing plate. Since the weight and viscosity of oily sludge of different concentrations are different, the viscosity of the oily sludge passing through the weighing plate is fed back through the height to which the weighing plate descends.

[0010] Furthermore, the spring adjustment column is provided with an adjustment sliding column, a spring threaded sleeve and a spring adjustment gear, the adjustment sliding column is arranged on the side weight plate positioning column, the side weight plate positioning column slides on the spring threaded sleeve, the spring threaded sleeve is threadedly connected to the adjustment column rotating seat, the spring adjustment gear is fixed to the bottom of the spring threaded sleeve, the adjustment knob is provided with a knob gear, the knob gear is meshed with the spring adjustment gear, and the spring threaded sleeve rotates at the bottom of the weighing slot.

[0014] Preferably, the descending height of the weighing plate is fed back to the proportioning slider through the dial plate, thereby pushing the proportioning slider to move. As the proportioning slider moves, the water pipe adjusting hole on the proportioning slider changes the pore size between the water inlet pipe and the water inlet hole, thereby changing the water inlet volume and adjusting the density of the waste oil sludge. Similarly, the pore size between the additive adjusting hole and the additive pipe and the additive hole will also change with the change of the waste oil sludge density, thereby achieving the technical effect of automatically adjusting the amount of demulsifier added.

Under the control of a one-step motor, the waste oil sludge is stirred and homogenized at high speed in the homogenization tank, and is slowly transported and precipitated in the auger tank, that is, the technical effect of continuous homogenization and sedimentation of the waste oil sludge is achieved.

The rotating auger blades can also clean the surface of the separation tank.

[0022] The beneficial effects achieved by the present invention using the above structure are as follows: 1. The oil sludge and demulsifier are quickly mixed by stirring the stirring shaft.

[0023] 2. Before the sludge enters the homogenizing tank from the feed pipe, it needs to pass through the weighing plate on the weighing tank. The sludge will press down the weighing plate. Because the weight and viscosity of sludge of different concentrations are different, the height to which the weighing plate descends will provide feedback on the viscosity of the sludge passing through the weighing plate.

[0024] 3. Different types of oily sludge have different density ranges. By turning the adjusting knob, the spring threaded sleeve of the spring adjusting column is driven to rotate, so that the spring adjusting plate at the bottom of the weighing plate moves up, thereby compressing the weighing spring to achieve the technical effect of adjusting the initial detection pressure of the weighing plate.

[0025] 4. The descending height of the weighing plate is fed back to the proportioning slider through the dial plate, thereby pushing the proportioning slider to move. As the proportioning slider moves, the water pipe adjusting hole on the proportioning slider changes the pore size between the water inlet pipe and the water inlet hole, thereby changing the water inlet volume and adjusting the density of the waste oil sludge. Similarly, the pore size between the additive adjusting hole and the additive pipe and the additive hole will also change with the change of the waste oil sludge density, thereby achieving the technical effect of automatically adjusting the amount of demulsifier added.

[0026] 5. The stirring shaft bevel gear of the stirring shaft drives the rotating shaft bevel gear to rotate, thereby driving the rotating shaft to rotate. The shaft sleeve has a sealing function to protect the stirring shaft bevel gear and the rotating shaft bevel gear.

[0027] 6. The rotating shaft gear of the rotating shaft drives the eccentric gear to rotate, and then drives the eccentric gear plate to rotate at a low speed. At the same time, the auger sleeve rotates with the eccentric gear plate, and the auger sleeve drives the auger blade to rotate slowly, giving the homogenized dirty oil sludge sufficient sedimentation time. Under the control of the one-step motor, the dirty oil sludge is stirred and homogenized at a high speed in the homogenizing tank, and slowly transported and precipitated in the auger tank, that is, the technical effect of continuous homogenization and sedimentation of the dirty oil sludge is achieved.

[0028] 7. The internal tooth ratchet makes the eccentric gear plate rotate in a directional manner to prevent the eccentric gear plate from rotating with the rotating shaft under the action of friction; the liquid floating on the dirty oil sludge flows out through the drain pipe of the separation tank, and the precipitated sludge is discharged through the discharge pipe. The rotating auger blades can also clean the surface of the separation tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] like Figure 1-Figure 10 As shown, the present invention proposes a continuous homogenizing device for treating waste oil sludge, comprising a homogenizing tank assembly 1, a weighing assembly 2, a proportioning assembly 3 and an auger tank assembly 4, wherein the weighing assembly 2 is arranged in the homogenizing tank assembly 1, the proportioning assembly 3 is arranged on the upper side of the homogenizing tank assembly 1, and the auger tank assembly 4 is connected to the bottom of the side wall of the homogenizing tank assembly 1; the homogenizing tank assembly 1 comprises a homogenizing tank 11 and a stirring shaft 12, a feed pipe 111 is arranged at the upper end of the side wall of the homogenizing tank 11, a weighing slot 1111 is arranged at the lower side of the feed pipe 111, the weighing assembly 2 is arranged in the weighing slot 1111, a water inlet hole 112 and an additive hole 113 are arranged on the upper wall of the homogenizing tank 11, and the stirring shaft 12 rotates on the homogenizing tank 11.

[0035] A motor 121 is disposed at the top of the stirring shaft 12 , and a bottom blade 122 is disposed at the bottom of the stirring shaft 12 . The bottom blade 122 rotates at the bottom of the homogenizing tank 11 . A stirring rod 123 and a stirring shaft bevel gear 124 are also disposed on the stirring shaft 12 .

[0036] Among them, the oil sludge and the demulsifier are quickly mixed through the stirring of the stirring shaft 12. The bottom blade 122 of the stirring shaft 12 is designed to be a blade with a low center and a high outside. While preventing the oil sludge from settling at the bottom, it creates a speed difference between the center and the edge of the oil sludge, forming a vortex, which promotes the demulsifier to quickly destroy the emulsion system in the sewage.

[0037] The weighing assembly 2 includes a weighing plate 21, a spring adjustment column 22 and an adjustment knob 23. The weighing plate 21 slides in the weighing slot 1111. A weighing spring 211, an adjustment column rotating seat 214 and a side weight plate positioning column 213 are provided at the bottom of the weighing plate 21. A spring adjustment plate 212 is provided at the bottom of the weighing spring 211. The adjustment column rotating seat 214 is located at the center of the weighing spring 211. A sealing baffle 215 is provided on the outside of the weighing plate 21. The sealing baffle 215 slides in the inner wall of the homogenizing tank 11, and the side weight plate positioning column 213 slides in the positioning groove on the weighing slot 1111.

[0038] Before the oily sludge enters the homogenizing tank 11 from the feed pipe 111, it needs to pass through the weighing plate 21 on the weighing tank 1111. The oily sludge will press down the weighing plate 21. Since the weight and viscosity of oily sludge of different concentrations are different, the viscosity of the oily sludge passing through the weighing plate 21 is fed back through the height to which the weighing plate 21 descends.

[0039] The spring adjustment column 22 is provided with an adjustment sliding column 221, a spring threaded sleeve 222 and a spring adjustment gear 223. The adjustment sliding column 221 is arranged on the side weight plate positioning column 213. The side weight plate positioning column 213 slides on the spring threaded sleeve 222. The spring threaded sleeve 222 is threadedly connected with the adjustment column rotating seat 214. The spring adjustment gear 223 is fixed at the bottom of the spring threaded sleeve 222. The adjustment knob 23 is provided with a knob gear 231. The knob gear 231 is meshed and connected with the spring adjustment gear 223. The spring threaded sleeve 222 rotates at the bottom of the weighing slot 1111.

[0040] Among them, different types of oily sludge have different density ranges. By turning the adjusting knob 23, the spring threaded sleeve 222 of the spring adjusting column 22 is driven to rotate, so that the spring adjusting plate 212 at the bottom of the weighing plate 21 moves up, and then compresses the weighing spring 211, thereby achieving the technical effect of adjusting the initial detection pressure of the weighing plate 21.

[0041] The proportioning component 3 includes a proportioning chute 31, a proportioning slider 32 and a paddle 34. The proportioning slider 32 slides in the proportioning chute 31. The proportioning chute 31 is arranged above the homogenizing tank 11. The proportioning chute 31 is provided with an additive tube 311 and a water inlet pipe 312. The additive tube 311 is located directly above the additive hole 113, and the water inlet pipe 312 is located directly above the water inlet hole 112. The bottom of the paddle 34 is arranged on the side weight plate positioning column 213, and the upper end cross bar of the paddle 34 is arranged on the proportioning slider 32.

[0042] The proportioning slider 32 is provided with a water pipe adjustment hole 321, an additive adjustment hole 322 and a slider return spring 323. The water pipe adjustment hole 321 is located between the water inlet hole 112 and the water inlet pipe 312, the additive adjustment hole 322 is located between the additive hole 113 and the additive pipe 311, the slider return spring 323 is arranged on the right side of the proportioning slider 32, and the left side of the proportioning slider 32 is designed as a slope. The cross bar on the dial plate 34 slides on the slope of the proportioning slider 32, and the slider return spring 323 is provided with a spring fixing plate 33, and the spring fixing plate 33 is arranged on the homogenizing tank 11.

[0043] Among them, the descending height of the weighing plate 21 is fed back to the proportioning slider 32 through the dial plate 34, thereby pushing the proportioning slider 32 to move. As the proportioning slider 32 moves, the water pipe adjustment hole 321 on the proportioning slider 32 changes the pore size between the water inlet pipe 312 and the water inlet hole 112, thereby changing the water intake and adjusting the density of the waste oil sludge. Similarly, the pore between the additive adjustment hole 322 and the additive pipe 311 and the additive hole 113 will also change with the change of the waste oil sludge density, thereby achieving the technical effect of automatically adjusting the amount of demulsifier added.

[0044] The auger tank assembly 4 includes a rotating shaft 41, an auger sleeve 42, an eccentric gear plate 43 and an auger tank 44. The rotating shaft 41 is arranged at the center of the auger sleeve 42. The auger sleeve 42 rotates on the auger tank 44. The eccentric gear plate 43 is arranged at the right end of the auger sleeve 42. The auger sleeve 42 is provided with an auger blade 421.

[0045] A rotating shaft gear 411 is provided at the right end of the rotating shaft 41, and a rotating shaft bevel gear 412 is also provided on the rotating shaft 41. The rotating shaft bevel gear 412 is meshed and connected with the stirring shaft bevel gear 124. A shaft sleeve 413 is provided on the outside of the rotating shaft bevel gear 412 and the stirring shaft bevel gear 124. The shaft sleeve 413 is rotatably connected to the rotating shaft 41, and the shaft sleeve 413 is rotatably connected to the stirring shaft 12.

[0046] The stirring shaft bevel gear 124 of the stirring shaft 12 drives the rotating shaft bevel gear 412 to rotate, thereby driving the rotating shaft 41 to rotate. The shaft sleeve 413 has a sealing function to protect the stirring shaft bevel gear 124 and the rotating shaft bevel gear 412 .

[0047] The eccentric gear disk 43 rotates outside the auger tank 44, and is provided with an eccentric gear 431, a wedge slot 432 and a locking wedge 433 on the eccentric gear disk 43. The eccentric gear 431 is meshed and connected with the rotating shaft gear 411, and the locking wedge 433 slides in the wedge slot 432. A wedge return spring 434 is provided at the bottom of the locking wedge 433, and the wedge return spring 434 is connected to the bottom of the wedge slot 432.

[0048] Among them, the rotating shaft gear 411 of the rotating shaft 41 drives the eccentric gear 431 to rotate, and then drives the eccentric gear plate 43 to rotate at a low speed. At the same time, the auger sleeve 42 rotates following the eccentric gear plate 43, and the auger sleeve 42 drives the auger blade 421 to rotate slowly, giving the homogenized waste oil sludge sufficient sedimentation time, so that under the control of a one-step motor, the waste oil sludge is stirred and homogenized at a high speed in the homogenizing tank 11, and is slowly transported and precipitated in the auger tank 44, that is, the technical effect of continuous homogenization and sedimentation of the waste oil sludge is achieved.

[0049] An inner toothed ratchet 442 is provided on the right outer wall of the auger tank 44 , a discharge pipe 441 is provided on the right bottom side of the auger tank 44 , a locking wedge 433 slides on the inner toothed ratchet 442 , a separation groove 443 is provided on the right top of the auger tank 44 , and a drainage pipe 444 is provided in the separation groove 443 .

[0050] Among them, the internal tooth ratchet 442 makes the eccentric gear plate 43 rotate in a directional manner to prevent the eccentric gear plate 43 from rotating with the rotating shaft 41 under the action of friction; the liquid floating on the dirty oil sludge flows out through the drain pipe 444 of the separation tank 443, and the precipitated sludge is discharged through the discharge pipe 441. The rotating auger blades 421 can also clean the surface of the separation tank 443.

[0051] During specific use, the dirty oil sludge is slowly injected into the homogenizing tank 11 from the feed pipe 111. When passing through the weighing plate 21 on the weighing slot 1111, the dirty oil sludge will press down the weighing plate 21, the weighing plate 21 moves down, the weighing spring 211 is compressed, the adjusting column rotating seat 214 drives the adjusting sliding column 221 to move down, and at the same time, the side weight plate positioning column 213 moves down, the side weight plate positioning column 213 drives the paddle plate 34 to move down, and the paddle plate 34 moves down and pushes the proportioning slider 32 to slide to the right, the gap between the water pipe adjusting hole 321 and the water inlet pipe 312 and the water inlet hole 112 increases, thereby increasing the water intake. Similarly, the gap between the additive adjusting hole 322 and the additive pipe 311 and the additive hole 113 increases, the amount of demulsifier injected increases, and at the same time, the slider reset spring 323 on the proportioning slider 32 is compressed. As the weight of the dirty oil sludge floats, the water intake and the amount of demulsifier added change accordingly.

[0052] When processing waste oil sludge of different properties, the threshold value of the waste oil sludge weight is different. Turn the adjusting knob 23, and the adjusting knob 23 drives the knob gear 231 to rotate. The knob gear 231 drives the spring adjusting gear 223 at the bottom of the spring adjusting column 22 to rotate. The spring adjusting gear 223 drives the spring threaded sleeve 222 to rotate. The spring threaded sleeve 222 is threadedly connected with the spring adjusting plate 212, and then the spring adjusting plate 212 moves up. At the same time, the spring adjusting plate 212 compresses the weighing spring 211, so that the elastic force of the weighing spring 211 on the lower side of the weighing plate 21 increases, that is, the initial measurement value of the weighing plate 21 increases, and the side weighing plate positioning column 213 has the function of fixing the initial position of the weighing plate 21.

[0053] After the dirty oil sludge enters the homogenizing tank 11, the motor 121 drives the stirring shaft 12 to rotate, and then the stirring rod 123 and the bottom blade 122 begin to stir and homogenize the dirty oil sludge, and at the same time, the stirring shaft bevel gear 124 on the stirring shaft 12 drives the rotating shaft bevel gear 412 to rotate, and the rotating shaft bevel gear 412 drives the rotating shaft 41 to rotate, and the rotating shaft gear 411 of the rotating shaft 41 rotates, and the rotating shaft gear 411 is meshed and connected with the eccentric gear 431 on the eccentric gear plate 43, thereby driving the eccentric gear plate 43 to rotate, and the eccentric gear plate 43 drives the auger shaft sleeve 42 to rotate. During the rotation of the eccentric gear plate 43, the internal tooth ratchet 442 on the auger tank 44 will squeeze the locking wedge 433, and the wedge reset spring 434 at the bottom of the locking wedge 433 will be reset. The compression and locking wedge block 433 slides into the wedge block slot 432, and at the same time prevents the eccentric gear plate 43 from rotating in the same direction as the rotating shaft 41 to cause the auger blade 421 to reverse. The auger blade 421 transports the homogenized oily sludge to the auger tank 44.
