[0002] Petrochemical industry, referred to as petrochemical industry, generally refers to the chemical industry using petroleum and natural gas as raw materials. Crude oil is cracked (cracking), reformed and separated to provide basic raw materials, from which various basic organic raw materials such as methanol, formaldehyde, ethanol, acetaldehyde, acetic acid, isopropanol, acetone, phenol, etc. can be produced;

[0015] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0016] 1. The present invention can perform dehydration operations on sludge with different water contents under different conditions by arranging a driving mechanism and a cleaning mechanism, thereby avoiding blockage during dehydration, and can perform cyclic dehydration and crushing dehydration on the sludge according to demand. According to different dehydration states, a mixing agent can be added during feeding and dehydration, and blockage removal and cleaning operations can be performed subsequently, so that the sludge can be dehydrated stably and efficiently without stopping, thereby ensuring high dehydration efficiency.

[0017] 2. The present invention can ensure the stability of dehydration by setting a driving mechanism, and can switch different driving states according to needs, so that the dehydration device can effectively dehydrate different sludges, and does not require a large number of driving motors, thereby reducing the energy consumption of the equipment.

[0018] 3. The present invention sets a constraint groove, a constraint rod and its peripheral components. The constraint rod cooperates with the guide barrel to move its position inside the dehydration barrel, and can be snap-fitted and installed inside the constraint groove. The guide barrel slides inside the rectangular groove of the constraint groove, so that the guide barrel can rotate synchronously with the dehydration barrel. The guide barrel can be slidably installed inside the constraint groove, and the guide barrel slides inside the circular groove of the constraint groove, so that the guide barrel can rotate synchronously with the first linkage rod, thereby ensuring the multi-state drive switching of the driving mechanism and providing a longer service life for the mechanical structure.

[0019] 4. The present invention sets a third gear, a second gear and a second gear ring. The second gear drives the second gear ring to rotate, which can cooperate with the first gear to drive the first gear ring to rotate, thereby ensuring that both ends of the dehydration barrel are driven to rotate stably and at high speed. The third gear drives the second gear to rotate, which can drive the first linkage rod to rotate. The second gear and the second gear ring have different major diameters. When driven by the third gear, different rotation speeds and rotation directions can be maintained, so that the dehydration barrel and the first linkage rod can be driven at different rotation speeds and rotation directions.

[0020] 5. The present invention sets a second electric push rod and a card block. When the second electric push rod pulls the card block, the first linkage rod will not generate driving force on the guide barrel when it rotates. The second electric push rod pushes the card block to fit the wall of the movable cavity so that the first linkage rod can synchronously drive the guide barrel to generate driving force when it rotates, so that the second motor can generate different driving states for use with various components.

[0021] 6. The present invention provides a cleaning mechanism, so that the corresponding mixed agent can be added during the sludge dewatering feeding and dewatering to ensure the subsequent sludge dewatering operation. In addition, when the dewatering is blocked, the blockage can be cleared to ensure the effective use of the dewatering without stopping the machine and the use efficiency of the device.

[0022] 7. The present invention provides a feed plate and its peripheral components, so that the feed plate can exert certain stability constraints on the dehydration barrel, ensuring that the dehydration barrel rotates stably without shaking, and the stable fit between the feed plate and the dehydration barrel can make the feed cavity and the material guide cavity correspond stably, facilitating the subsequent circulation and use of the mixture and water.

The second gear 254 is arranged at the lower side of the working barrel 1. The second gear 254 is an I-shaped circular ring gear with a spline shape on the inner side. A second gear ring 256 is fixedly installed on the lower side of the dehydration barrel 21 and the second gear ring 256 extends through the bottom side of the working barrel 1. The second gear ring 256 is a "C" center ring with a tooth shape on the inner side. A third gear 255 is meshed between the inner side of the second gear ring 256 and the outer side of the second gear 254. The third gear 255 is a circular gear. The third gear 255 is limited by the second gear ring 256 and the second gear 254.A second motor 257 is fixedly installed on the side of the third gear 255, and the second motor 257 is fixed to the lower side of the working barrel 1 through a support frame. A first electric push rod 26 is arranged at the lower end of the first linkage rod 25, and the output end of the first electric push rod 26 is rotatably installed with the first linkage rod 25. The first electric push rod 26 is fixed to the lower side of the working barrel 1 through a support frame. A second electric push rod 27 is fixedly installed at the upper end of the first linkage rod 25, and a clamping block 271 is fixedly installed at the output end of the second electric push rod 27, and the clamping block 271 is movably arranged at the upper end of the first linkage rod 25. The second electric push rod 27 and the clamping block 271 are both arranged in the internal position of the movable cavity 244, and a discharge pipe 28 is fixedly arranged on the side of the second gear ring 256, and the discharge pipe 28 passes through the dehydration The barrel 21 extends to its internal bottom side position, and the discharge pipe 28 is a circular tube with an electric control valve on the side; specifically, when used by default, the first electric push rod 26 can push the first linkage rod 25 to perform lifting movements, and the first electric push rod 26 pushes the first linkage rod 25 to drive the guide barrel 24 to move. At this time, the constraint rod 241 is clamped in the constraint groove 23 (the constraint rod 241 is slidably installed in the rectangular groove of the constraint groove 23), and the second electric push rod 27 pulls the block 271, and then the second motor 257 drives the third gear 255 to engage and rotate with the second gear ring 256 and the second gear 254, and drives the dehydration barrel 21 to rotate through the second gear ring 256, and drives the first linkage rod 25 to rotate through the second gear 254, and the dehydration barrel 21 rotates with the first linkage rod 25 The rotation directions are opposite and the rotation speeds are different. The synchronous first motor 222 drives the first gear 221 to mesh with the constraint groove 23 and can drive the dehydration barrel 21 to rotate at the same time, so that the dehydration barrel 21 can be driven to rotate and dehydrate as a whole. At this time, the guide barrel 24 and the dehydration barrel 21 rotate synchronously and are relatively stationary. The material can be driven by the first linkage rod 25 to drive the conveying plate 251 to rotate in the direction for conveying, and then discharged through the slot 243, so that the material can be cyclically dehydrated. Among them, the first linkage rod 25 can also be pushed and pulled by the first electric push rod 26 to drive the guide barrel 24 to move its position inside the dehydration barrel 21, so that the upper conical surfaces between the guide barrel 24 and the dehydration barrel 21 cooperate to adjust the spacing, so that the speed at which the material flows into the dehydration barrel 21 can be controlled.

At this time, the constraint rod 241 is slidably installed in the constraint groove 23, and the second electric push rod 27 pushes the block 271 to fit the wall of the active cavity 244.

The guide barrel 24 and the conveying plate 251 are relatively stationary and will not convey the material. The guide barrel 24 and the dewatering barrel 21 rotate in opposite directions. The constraint rod 241 drives the cleaning rod 242 to scrape the inside of the dewatering barrel 21 and cut and crush the sludge at the same time.

[0037] The cleaning mechanism 3 can be used to synchronously add a mixed agent to the sludge to assist in dehydration, and can also be used to clear the blockage in the dehydration process and perform self-cleaning operations in the later stage;

[0038] like Figures 2 to 9As shown, the cleaning mechanism 3 includes a feed plate 31 fixedly mounted on the top wall of the working barrel 1, and the feed plate 31 is attached to the side of the dehydration barrel 21. The feed plate 31 is a circular plate with a trapezoidal cross-section. The feed plate 31 can stabilize the dehydration barrel 21. A feed cavity 311 is provided on the side of the feed plate 31 close to the dehydration barrel 21. The feed cavity 311 is a circular groove with a trapezoidal cross-section. A feed pipe 312 is provided on the upper side of the working barrel 1, which passes through the working barrel 1 and the feed plate 31 to the inside of the feed cavity 311, and the other end of the feed pipe 312 is connected to the feed module of the mixture and water. The feed pipe 312 is a circular tube. A guide cavity 32 is provided on the side of the dehydration barrel 21 corresponding to the position of the feed cavity 311. The guide cavity 32 is a circular cavity with an "F"-shaped cross-section. , discharge holes 321 penetrating the dewatering barrel 21 are equidistantly provided in a circular array on the side wall of the material guiding chamber 32, and the discharge holes 321 are circular holes, and mounting chambers 322 are equidistantly provided in a circular array on the bottom wall of the material guiding chamber 32, and the mounting chambers 322 are rectangular chambers, and filtering holes 33 penetrating therethrough are equidistantly provided on the side of the dewatering barrel 21 corresponding to the mounting chamber 322, and the filtering holes 33 are circular holes, and a trigger plate 34 is movably installed inside the material guiding chamber 32, and both sides of the trigger plate 34 are attached to the wall of the material guiding chamber 32, and the trigger plate 34 is a circular plate made of elastic material, and a support cylinder 341 is symmetrically fixedly connected between the side surface of the trigger plate 34 and the wall of the material guiding chamber 32, and the support cylinder 341 is a cylinder made of elastic material with a continuous "W"-shaped cross section, and a filter hole 33 is formed on the side surface of the trigger plate 34. A second linkage rod 342 is fixedly installed in a circumferential array at equal intervals, and the second linkage rod 342 is movably installed in a position inside the installation cavity 322. The second linkage rod 342 is composed of multiple groups of circular rings and rectangular rods on the side, and the position of the circular ring is set corresponding to the position of the filter hole 33. A discharge groove 343 extending from multiple points through the second linkage rod 342 is opened on the upper side of the second linkage rod 342, and the discharge groove 343 penetrates the trigger plate 34. The discharge groove 343 is a multi-point rectangular groove, and water can enter through one end of the discharge groove 343 or the mixture can be discharged from multiple points. A matching groove 35 that penetrates the dehydration barrel 21 to the inside of the guide cavity 32 is symmetrically opened on the side of the dehydration barrel 21, and the matching groove 35 is a circular groove. A third electric push rod 351 is fixedly installed on the lower side of the feed plate 31, and the third electric push rod 351 corresponds to The position of the matching groove 35; specifically, the mixture or water can flow into the feed chamber 311 to the inside of the guide chamber 32 through the guide chamber 32. By default, the trigger plate 34 supports the guide chamber 32 to spatially separate the mixture and water. At this time, the mixture and water can only be discharged through the discharge hole 321; when the output end of the third electric push rod 351 pushes the support cylinder 341 through the matching groove 35, the synchronous support cylinder 341 drives the second linkage rod 342 to slide inside the installation chamber 322, and the circular ring block of the second linkage rod 342 is staggered with the inside of the filter hole 33. At this time, the mixture or water flows in from one end of the discharge groove 343 and then flows out from other multiple points to the inside of the filter hole 33. In this way, the material can be added with a mixture or the inside of the water cleaning constraint groove 23 can be prevented from being blocked.

[0039] Working principle:

[0040] During normal sludge dehydration: the sludge is transported to the inside of the dehydration barrel 21 through the pipeline and the first electric push rod 26 can push and pull the first linkage rod 25 to move, so that the guide barrel 24 moves accordingly, and the conical surface gap between the dehydration barrel 21 is adjusted. At this time, the constraint rod 241 is clamped in the inner position of the constraint groove 23. At this time, the dehydration barrel 21 and the guide barrel 24 are relatively stationary, and the sludge is guided by the dehydration barrel 21 and the guide barrel 24;

[0041] The synchronous second motor 257 drives the third gear 255 to rotate and mesh with the second gear ring 256 and the second gear 254, and drives the dewatering barrel 21 and the first linkage rod 25 to rotate in opposite directions at different speeds through the second gear ring 256 and the second gear 254. The first motor 222 drives the first gear 221 to mesh with the first gear ring 22 and drives the dewatering barrel 21 to rotate at the same time, so as to ensure that the dewatering barrel 21 performs a high-speed and stable rotation and dehydration operation. At the same time, the first linkage rod 25 drives the conveying plate 251 to rotate and rotates in the opposite direction to the guide barrel 24, and the sludge at the bottom of the dewatering barrel 21 is transported to the slot 243 for discharge, and the sludge is circulated and dehydrated to ensure the dehydration effect. When appropriate, the electric control valve on the side of the discharge pipe 28 is controlled to open, and the sludge dehydrated by gravity and pipeline pressure is discharged from the discharge pipe 28 to the lower end collection conveyor belt for centralized collection;

[0042] When the relatively dry sludge is dehydrated: the first electric push rod 26 pulls the first linkage rod 25 to make the guide barrel 24 move downward inside the dehydration barrel 21. At this time, the constraint rod 241 is slidably installed inside the constraint groove 23, and the second electric push rod 27 pushes the block 271 to fit the wall of the movable cavity 244 to lock the first linkage rod 25 and the guide barrel 24. At this time, the first linkage rod 25, the conveying plate 251 and the guide barrel 24 rotate synchronously and are relatively stationary, and the guide barrel 24 and the dehydration barrel 21 rotate in the opposite direction. The constraint rod 241 slides and rotates inside the constraint groove 23 and drives the cleaning rod 242 to rotate accordingly. The cleaning rod 242 scrapes the inside of the dehydration barrel 21 and performs sludge crushing operations to avoid sludge agglomeration and blockage. In addition, the dehydration process can be switched to the normal sludge dehydration state, so that the sludge can be properly circulated and dehydrated, further ensuring the dehydration effect, and can be adapted to the dehydration of sludge with different water contents;

[0043] When the sludge dehydration is almost finished, the above state can also be switched to make the remaining sludge be dehydrated and discharged quickly to avoid the slow circulation and discharge of the remaining sludge;

[0044] When a mixture needs to be added: By default, the trigger plate 34 is supported by the support tube 341 to isolate the inside of the guide cavity 32. At this time, the guide cavity 32 allows the mixture to flow into the feed cavity 311 to the inside of the guide cavity 32, and after being discharged from the discharge hole 321, it can be mixed with the sludge at the feed point; in addition, when the mixture is needed for dehydration, the third electric push rod 351 presses the trigger plate 34 to slide downward, and the mixture is discharged from the discharge groove 343 to the inner position of the filter hole 33, and the above-mentioned state of sludge crushing is used to accelerate the mixing of the mixture and the sludge;

[0045] When dehydration is blocked or self-cleaning: when the constraint groove 23 is blocked, the third electric push rod 351 presses the trigger plate 34 downward, so that water can flow into the constraint groove 23 through the discharge groove 343 to perform a clearing operation. After use, water flows into the dehydration barrel 21 from the discharge hole 321 and the discharge groove 343. When the water is filled in the working barrel 1, by driving the dehydration barrel 21, the guide barrel 24, the first linkage rod 25 and the conveying plate 251 to rotate, the various components can be stirred and cleaned. After cleaning, the sewage can be discharged centrally through the drain pipe 11.

[0046] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
