Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment equipment, and in particular to livestock and poultry breeding wastewater treatment equipment. Background Art

[0002] Livestock breeding wastewater treatment equipment is a system specially used to treat high-concentration organic wastewater such as feces, urine, and flushing water generated by farms (such as pigs, cattle, chickens, etc.). It aims to reduce pollution, achieve resource utilization or meet emission standards. The snail stacker is the most common type of livestock breeding wastewater treatment equipment.

[0003] The existing sludge dewatering snail stacking machine mainly uses the interlaced and staggered rotation of the dynamic ring pieces and the static ring pieces in combination with the pressurization of the stirring paddle to separate and treat the sewage by extrusion. When the snail stacking machine is used in the livestock breeding industry, since the sludge contains a large amount of impurities such as fibers and hair, it is easy for the dynamic and static ring pieces of the snail stacking machine to be blocked during the interlaced operation, thereby affecting the operating efficiency of the equipment. In addition, due to the special structure of the dynamic and static ring pieces, the traditional snail stacking machine is difficult to clean after being blocked, and its applicability and ease of use need to be further improved. Summary of the Invention

[0004] The present invention discloses a livestock and poultry breeding wastewater treatment equipment, which aims to solve the technical problems that the existing spiral-stacked sewage treatment equipment is prone to blockage when used in the livestock breeding industry, affecting the operating efficiency of the equipment, and is difficult to clean after blockage due to its own special structure, and its applicability and ease of use need to be further improved.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A livestock and poultry breeding wastewater treatment device comprises a sedimentation tank, a dewatering tank installed through the side of the sedimentation tank, a separation mechanism for solid-liquid separation of sewage is provided inside the dewatering tank, the separation mechanism comprises a first back plate and a second back plate symmetrically installed at both ends of the dewatering tank, a plurality of frame rods are fixedly connected between the first back plate and the second back plate, and a plurality of evenly distributed dynamic ring plates and rubber rings are slidably sleeved on the outer sides of the frame rods; The end of the separation mechanism is provided with a driving mechanism for switching the working mode of the separation mechanism, and the driving mechanism includes a sleeve fixedly mounted on the inner side of the first back plate, a group of electric push rods are symmetrically mounted on the upper and lower ends of the sleeve, and a driving plate is slidably sleeved on the outer side of the sleeve; The separation mechanism is driven by the driving mechanism to operate, thereby switching the working modes to realize filtering and cleaning functions respectively.

[0006] By arranging a separation mechanism inside the dewatering box and adding flocculants to the sewage by using the sedimentation box, the sewage produces blooming sludge and the sludge is transported to the inside of the dewatering box. Under normal circumstances, the sludge is dehydrated by opening and closing and squeezing the separation mechanism slightly, and the sludge and water flow are separated. On the premise of achieving the working efficiency of the traditional screw stacking machine, the opening and closing dehydration method is not easy to cause blockage. When the worker wants to clean the equipment, the driving mechanism is used to drive the separation mechanism to change the working mode, causing the separation mechanism to open and close and tilt significantly, thereby facilitating flushing and cleaning, thereby improving the cleaning efficiency and convenience of traditional equipment.

[0007] In a preferred embodiment, the separation mechanism also includes a variable diameter stirring paddle rotatably installed inside the dehydration box, the end of the variable diameter stirring paddle passes through the side of the dehydration box and is connected to a reduction motor, the dynamic ring pieces are distributed on the outside of the variable diameter stirring paddle, and several of the dynamic ring pieces are connected to each other through the rubber ring.

[0008] By setting the staggered operation mode of the dynamic ring and the static ring of the traditional spiral stacked sewage treatment equipment to be composed of a single dynamic ring, a driving mechanism is used to drive several dynamic rings to squeeze the rubber rings to open and close slightly, leaving a gap during opening and closing for the sewage squeezed by the variable diameter stirring paddle to be dehydrated, and the rubbing stagger of the traditional equipment is changed to a lateral moving stagger, thereby greatly reducing the probability of equipment blockage while reducing the complexity and cost of equipment operation.

[0009] In a preferred solution, the driving mechanism also includes the driving plate, whose inner diameter is larger than the outer diameter of the sleeve and equal to the inner diameter of the dynamic ring piece, and a group of slide members are respectively provided on the side surfaces of the upper and lower ends of the driving plate, the output end of the electric push rod is slidably connected to the slide member, the driving plate and the single dynamic ring piece close to it are fixedly connected, the moving dynamic ring piece is slidably sleeved on the outside of the sleeve, and the outer side of the single frame rod located above is sequentially welded with longitudinal extrusion parts and transverse extrusion parts, and the moving dynamic ring piece is squeezed and contacted with the longitudinal extrusion parts and the transverse extrusion parts in turn, and a flushing row is arranged above the interior of the dehydration box, and the flushing rows are distributed above several of the dynamic ring pieces.

[0010] A sleeve structure is provided on the side of the first back plate, and a group of electric push rods are symmetrically provided at the upper and lower ends of the sleeve, and the electric push rods and the drive plate are slidably connected by a slide groove component. When the two electric push rods are slightly extended and retracted, the drive plate can drive several dynamic ring pieces to move synchronously, thereby utilizing an opening and closing manner to dewater the sewage; when the two electric push rods are pulled greatly, the drive plate can drive several dynamic ring pieces to move synchronously, thereby increasing the gap spacing of the dynamic ring pieces, and coordinating with the reciprocating and different-frequency extension and contraction of the two electric push rods to drive the dynamic ring pieces to tilt in different directions, and coordinating with the flushing of the flushing drain, thereby greatly improving the cleaning efficiency and convenience of the traditional screw stacking machine, and the dynamic ring pieces will be squeezed and pushed by the transverse extrusion piece and the longitudinal extrusion piece when they move, thereby synchronously shaking, thereby further improving the cleaning efficiency.

[0011] In a preferred embodiment, a plurality of embedded grooves are symmetrically provided on both sides of the dynamic ring piece, the ends of the rubber rings are connected to the inside of the embedded grooves, and the dynamic ring pieces that are fitted together are squeezed so that the rubber rings are hidden inside the embedded grooves.

[0012] By symmetrically arranging the embedded groove structure on both sides of the dynamic ring piece, when the dynamic ring piece is squeezed, the deformed rubber ring will be hidden inside the embedded groove, thereby maintaining the sealing between the two dynamic ring pieces and improving the integrity of the equipment operation.

[0013] In a preferred solution, a rubber sleeve is fixedly sleeved on the outer side of the sleeve, the outer diameter of the rubber sleeve is larger than the inner diameter of the driving plate, and the rubber sleeve is in extrusion contact with the driving plate.

[0014] By arranging a rubber sleeve structure on the outside of the sleeve, when the driving plate drives the moving ring to tilt, it can contact the outside of the rubber sleeve in an extrusion deformation manner, while maintaining the sealing between the sleeve and the driving plate, preventing the sludge that has not been dehydrated from falling from the gap, thereby improving the operation integrity of the equipment.

[0015] From the above, it can be seen that the livestock and poultry breeding wastewater treatment equipment provided by the present invention has the following technical effects.

[0016] First: By changing the staggered operation mode of the dynamic ring and the static ring of the traditional spiral stacked sewage treatment equipment to a horizontal movement mode of a single dynamic ring, and coordinating with the relative extrusion of the rubber ring, a small opening and closing is performed. When opened, a gap is left for the sewage squeezed by the variable diameter stirring paddle to be dehydrated, and when closed, a sealed chamber is formed for the variable diameter stirring paddle to pressurize the sewage. The dehydration mode of the traditional equipment with rubbing and staggering is changed to horizontal movement and staggering, thereby reducing the operation complexity and production cost of the equipment, and greatly reducing the probability of equipment blockage, thereby improving the integrity of the operation of the traditional equipment.

[0017] Secondly, a sleeve structure is provided on the side of the first back plate, and a group of electric push rods are symmetrically provided at the upper and lower ends of the sleeve. The electric push rods and the drive plate are slidably connected by a slide groove component. When the two electric push rods are pulled significantly, several dynamic ring pieces can be driven to move synchronously through the drive plate, thereby increasing the gap spacing of the dynamic ring pieces. The reciprocating and differential frequency extension and contraction of the two electric push rods cause the dynamic ring pieces to tilt in different directions. The flushing of the flushing drain can clean both sides of the dynamic ring pieces, thereby greatly improving the cleaning efficiency and operating convenience of the traditional screw stacking machine. When the dynamic ring pieces move, they will be squeezed and pushed by the additionally provided transverse extrusion pieces and longitudinal extrusion pieces, thereby causing synchronous transverse and longitudinal vibrations, thereby further improving the cleaning efficiency.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] The livestock and poultry breeding wastewater treatment equipment disclosed in the present invention is mainly used in the scenario of treating breeding wastewater.

[0029] Reference Figures 1 to 8 A livestock and poultry breeding wastewater treatment device includes a sedimentation box 1 and a dehydration box 2 installed through the side of the sedimentation box 1. The dehydration box 2 is provided with a separation mechanism 3 for solid-liquid separation of sewage. The separation mechanism 3 includes a first back plate 303 and a second back plate 304 symmetrically installed at both ends of the dehydration box 2. A plurality of racks 305 are fixedly connected between the first back plate 303 and the second back plate 304. A plurality of evenly distributed dynamic ring pieces 306 and rubber rings 307 are slidably sleeved on the outer sides of the racks 305. The end of the separation mechanism 3 is provided with a drive mechanism 4 for switching the working mode of the separation mechanism 3. The drive mechanism 4 includes a sleeve 401 fixedly mounted on the inner side of the first back plate 303. A set of electric push rods 402 are symmetrically mounted on the upper and lower ends of the sleeve 401. A drive plate 403 is slidably sleeved on the outer side of the sleeve 401. The separation mechanism 3 is driven by the driving mechanism 4 to operate, thereby switching the working modes to realize the filtering and cleaning functions respectively.

[0030] In this embodiment: workers use an external pump to introduce the preliminarily treated sewage into the interior of the sedimentation tank 1, and at the same time pour flocculant into the interior of the sedimentation tank 1. The flocculant will flocculate the solids in the sewage into sludge and float it above the liquid surface. At this time, the paddle pump located inside the sedimentation tank 1 is running to introduce the sludge floating inside the sedimentation tank 1 into the interior of the dewatering tank 2. At this time, the separation mechanism 3 starts to operate and transports the sludge to the end of the dewatering tank 2. While transporting, it opens and closes slightly, causing the sludge to be squeezed, and the water in the sludge is directly removed from the separation mechanism 3, while the solid sludge is directly discharged from the end of the dewatering tank 2; when the worker needs to clean the separation mechanism 3, the drive mechanism 4 is started at this time, and the drive mechanism 4 changes the opening and closing amplitude of the separation mechanism 3, causing the separation mechanism 3 to open and tilt significantly, and at the same time, the surface of the separation mechanism 3 is rinsed by water.

[0031] Among them, a drug adding interval 101 is provided at the end of the sedimentation box 1, and the interior of the drug adding interval 101 is filled with flocculant, and the dehydration box 2 is tilted as a whole, and a discharge plate 201 is fixedly installed at the inclined end at the top of the dehydration box 2, which is used to discharge the dehydrated solid sludge, and a drainage channel 202 is installed at the bottom of the dehydration box 2. The drainage channel 202 is distributed directly below several dynamic ring pieces 306 and is used to discharge the water removed from the sludge, and a back pressure plate 308 is fixedly installed on the outside of the end of the variable diameter stirring paddle 301. The back pressure plate 308 is distributed above the discharge plate 201, which can increase the pressure when the sludge inside the dynamic ring piece 306 is squeezed.

[0032] Reference Figures 1 to 5 、 Figures 7 and 8 In a preferred embodiment, the separation mechanism 3 also includes a variable diameter stirring paddle 301 rotatably installed inside the dehydration box 2. The end of the variable diameter stirring paddle 301 passes through the side of the dehydration box 2 and is connected to a reduction motor 302. The dynamic ring pieces 306 are distributed on the outside of the variable diameter stirring paddle 301. At the same time, several dynamic ring pieces 306 are connected to each other by rubber rings 307.

[0033] The paddle pump located inside the sedimentation box 1 runs, and the sludge floating inside the sedimentation box 1 is introduced into the interior of the dewatering box 2. At this time, the reduction motor 302 starts to run, and the reduction motor 302 drives the variable diameter stirring paddle 301 to rotate, while rotating, the sludge is transported from the inside of several dynamic ring pieces 306 to the end of the dewatering box 2. While transporting, the driving mechanism 4 starts to run, and the driving mechanism 4 drives several dynamic ring pieces 306 to move slightly along the outside of the frame rod 305. When the dynamic ring pieces 306 move close to each other, they will squeeze the rubber ring 307, causing the rubber ring 307 to be compressed. At the same time, the dynamic ring pieces 306 are attached to each other to form a closed chamber, causing the sludge inside the closed chamber to be squeezed. When the dynamic ring pieces 306 move apart from each other, they will pull the rubber ring 307, causing the rubber ring 307 to stretch and pull all the dynamic ring pieces 306 in turn, causing gaps to appear between the dynamic ring pieces 306, and the squeezed water flows out directly from the gaps, and this cycle repeats.

[0034] Among them, several embedded grooves 3061 are symmetrically opened on both sides of the dynamic ring piece 306, and the ends of the rubber ring 307 are connected to the inside of the embedded groove 3061. The dynamic ring pieces 306 that are fitted together are squeezed so that the rubber ring 307 is hidden inside the embedded groove 3061, thereby maintaining the sealing of the dynamic ring pieces 306 after fitting.

[0035] Furthermore, a plurality of empty slots 4031 are formed through the interior of the driving plate 403 , and the rack rods 305 are distributed inside the empty slots 4031 .

[0036] Reference Figures 4 to 8In a preferred embodiment, the driving mechanism 4 also includes a driving plate 403 whose inner diameter is larger than the outer diameter of the sleeve 401 and is equal to the inner diameter of the dynamic ring piece 306. A group of slide members 404 are respectively provided on the side surfaces of the upper and lower ends of the driving plate 403. The output end of the electric push rod 402 is slidably connected to the slide member 404. The driving plate 403 is fixedly connected to a single dynamic ring piece 306 close to it. The moving dynamic ring piece 306 is slidably sleeved on the outside of the sleeve 401. The outer side of the single frame rod 305 located above is sequentially welded with longitudinal extrusion parts 405 and transverse extrusion parts 406. The moving dynamic ring piece 306 is squeezed and contacted with the longitudinal extrusion parts 405 and transverse extrusion parts 406 in turn. A flushing row 407 is mounted above the interior of the dehydration box 2, and the flushing rows 407 are distributed above several dynamic ring pieces 306.

[0037] When the two electric push rods 402 run synchronously and reciprocate with a small extension and retraction output end, the drive plate 403 connected to the electric push rod 402 will be driven synchronously, thereby driving a single dynamic ring piece 306 to move a small amount, and the moving single dynamic ring piece 306 will pull all the dynamic ring pieces 306 in turn through the rubber ring 307, thereby cooperating with the operation of the variable diameter stirring paddle 301 to dehydrate the sludge; when the worker needs to clean the dynamic ring piece 306, the worker controls the two electric push rods 402 to retract the output shaft significantly, and the retraction is simultaneous When the single moving ring piece 306 is driven to move synchronously, the moving single moving ring piece 306 will pull all the moving ring pieces 306 in turn through the rubber ring 307, causing the gap between the moving ring pieces 306 to increase. At this time, the worker controls the output shaft of the single electric push rod 402 to extend outward. While extending, the output end of the electric push rod 402 will slide along the inside of the corresponding slide member 404 and push the driving plate 403 to tilt. The tilted driving plate 403 will intermittently push all the moving ring pieces 306 through the rubber ring 307, causing the moving ring pieces 306 to tilt. The specific state is as follows Figure 8 As shown; at this time, the flushing drain 407 is connected and the inclined surface of the movable ring piece 306 is sprayed with water for cleaning. During cleaning, the two electric push rods 402 perform alternate extension and retraction of the output ends, thereby driving the movable ring piece 306 to tilt back and forth left and right, and the flushing drain 407 is used to flush the two surfaces of the movable ring piece 306. While the movable ring piece 306 moves and tilts, the movable ring piece 306 will be squeezed and contacted with the longitudinal extrusion piece 405 and the transverse extrusion piece 406 in turn, thereby causing longitudinal and transverse shaking, thereby improving cleaning efficiency.

[0038] It should be noted that a rubber sleeve 408 is fixed to the outer side of the sleeve 401. The outer diameter of the rubber sleeve 408 is larger than the inner diameter of the driving plate 403. At the same time, the rubber sleeve 408 and the driving plate 403 are in squeeze contact. When the driving plate 403 is tilted, the squeezed rubber sleeve 408 can maintain the sealing between the driving plate 403 and the sleeve 401.

[0039] Working principle: When in use, workers use an external pump to introduce the preliminarily treated sewage into the interior of the sedimentation tank 1, and at the same time pour flocculants into the interior of the sedimentation tank 1. The flocculants will flocculate the solids in the sewage into sludge and float it above the liquid surface. At this time, the paddle pump inside the sedimentation tank 1 is running, and the sludge floating inside the sedimentation tank 1 is introduced into the interior of the dewatering tank 2. At this time, the reduction motor 302 starts to run, and the reduction motor 302 drives the variable diameter stirring paddle 301 to rotate. While rotating, the sludge is transported from the inside of several dynamic ring pieces 306 to the end of the dewatering tank 2. While transporting, the two electric push rods 402 run synchronously and move forward. When the output end of the complex small extension and contraction is performed, the driving plate 403 connected to the electric push rod 402 will be synchronously driven and drive the dynamic ring piece 306. When the dynamic ring pieces 306 move close to each other, they will squeeze the rubber ring 307, causing the rubber ring 307 to be compressed. At the same time, the dynamic ring pieces 306 are fitted together to form a closed chamber, causing the sludge inside the closed chamber to be squeezed. When the dynamic ring pieces 306 move apart from each other, they will pull the rubber ring 307, causing the rubber ring 307 to deform and stretch and pull all the dynamic ring pieces 306 in turn, causing gaps to appear between the dynamic ring pieces 306, and the squeezed water will flow out directly from the gaps, and the processing work is completed in this reciprocating manner; When the worker needs to clean the dynamic ring piece 306, the worker controls the two electric push rods 402 to significantly contract the output shafts, and at the same time drives the single dynamic ring piece 306 to move synchronously. The moving single dynamic ring piece 306 will pull all the dynamic ring pieces 306 in turn through the rubber ring 307, causing the gap between the dynamic ring pieces 306 to increase. At this time, the worker controls the output shaft of the single electric push rod 402 to extend outward. At the same time, the output end of the electric push rod 402 will slide along the inside of the corresponding slide member 404 and push the drive plate 403 to tilt. The tilted drive plate 403 will intermittently push all the dynamic ring pieces 306 through the rubber ring 307, causing the dynamic ring pieces 306 to tilt. The specific state is as follows: Figure 8 As shown; at this time, the flushing drain 407 is connected and the inclined surface of the movable ring piece 306 is sprayed with water for cleaning. During cleaning, the two electric push rods 402 perform alternate extension and retraction of the output ends, thereby driving the movable ring piece 306 to tilt back and forth left and right, and the flushing drain 407 is used to flush the two surfaces of the movable ring piece 306. While the movable ring piece 306 moves and tilts, the movable ring piece 306 will be squeezed and contacted with the longitudinal extrusion piece 405 and the transverse extrusion piece 406 in turn, thereby causing longitudinal and transverse shaking, thereby improving cleaning efficiency.
