Description

Technical Field

[0001] This invention relates to the field of sludge pump anti-clogging technology, and in particular to a crushing structure and a sludge pump anti-clogging device. Background Technology

[0002] A sludge pump is a conveying machine used to discharge sludge with high viscosity concentration. Sludge pumps are generally used for conveying sludge before dewatering and for papermaking sludge. For sludge dewatered by a filter press, a rotary pump is generally used for conveying. Through sedimentation in the sludge tank, a large amount of sludge will accumulate at the bottom of the tank. When the sludge accumulates to a certain amount, it needs to be pumped out of the sludge tank.

[0003] In the existing technology, when extracting sludge, the sludge pump often experiences blockage in the inlet pipe due to the large amount of solids in the sludge. This requires the sludge pump to be shut down for cleaning, which wastes a lot of the staff's time and results in low sludge extraction efficiency. Summary of the Invention

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figures 1-3 This is the first embodiment of the present invention. This embodiment provides a crushing structure, which includes a processing mechanism 100. The processing mechanism 100 includes a power unit 101, a stirring unit 102 disposed below the power unit 101, and a crushing unit 103 disposed on one side of the stirring unit 102. The power unit 101, the stirring unit 102 and the crushing unit 103 are used in cooperation. The power unit 101 can provide the power required for the operation of the device. The stirring unit 102 can reduce the solidification of the sludge by stirring it, and prevent the sludge from clogging at the connecting pipe 203. The crushing unit 103 can crush larger sludge lumps in the sludge, and prevent the sludge pump from clogging.

[0033] Specifically, the power unit 101 includes a servo motor 101a, a drive wheel 101b fixed to the output end of the servo motor 101a, and a belt 101c disposed on the drive wheel 101b. The drive wheel 101b and the belt 101c are adapted to each other. The servo motor 101a provides the required power to the device. The drive wheel 101b and the belt 101c enable the control of the stirring unit 102 and the crushing unit 103, thereby realizing the operation of the stirring unit 102 and the crushing unit 103.

[0034] Specifically, the stirring unit 102 includes a first fixed column 102a, a first sealed bearing 102b fixedly sleeved on the outer rings of both ends of the first fixed column 102a, and a spiral blade 102c fixedly sleeved on the middle outer ring of the first fixed column 102a. A first driven wheel 102d is fixedly sleeved on one end of the first fixed column 102a. The first driven wheel 102d is located outside the first sealed bearing 102b on one side. The arrangement of the first sealed bearing 102b can ensure the smooth rotation of the first fixed column 102a and also prevent sludge from affecting the rotation of the first fixed column 102a. The spiral blade 102c can stir the sludge and prevent the sludge from clogging in the connecting pipe 203.

[0035] In use, by turning on the servo motor 101a, the servo motor 101a drives the drive wheel 101b to rotate. The rotation of the drive wheel 101b, through the cooperation of the belt 101c and the first driven wheel 102d, drives the first fixed column 102a to rotate. The rotation of the first fixed column 102a drives the spiral blade 102c to rotate, thereby agitating the sludge and separating it. This prevents the large amount of solid sludge entering the connecting pipe 203 from causing blockage. At the same time, the agitation by the spiral blade 102c ensures the flow of the sludge and also helps the crushing unit 103 to crush the mud blocks in the sludge.

[0036] Example 2

[0037] Reference Figures 4-8 This is the second embodiment of the present invention, which differs from the first embodiment in that it further includes a crushing unit 103, comprising a transmission assembly 103a, a first crushing assembly 103b sleeved on the outer ring of the transmission assembly 103a, and a second crushing assembly 103c disposed on one side of the transmission assembly 103a. Through the cooperation between the transmission assembly 103a, the first crushing assembly 103b, and the second crushing assembly 103c, the crushing effect on the mud can be achieved. At the same time, through the cooperation between the first crushing assembly 103b and the transmission assembly 103a, the movement of the first crushing assembly 103b and the movement of the first sealing bearing 102b can be achieved, which can increase the crushing effect on the mud and prevent the sludge pump from becoming blocked.

[0038] Specifically, the transmission assembly 103a includes a second fixed post 103a-1, two second sealed bearings 103a-2 fixedly sleeved on the outer ring of the second fixed post 103a-1, a first gear 103a-4 fixed to one end of the second fixed post 103a-1, and a second driven wheel 103a-3 fixed to one end of the second fixed post 103a-1. A fixed plate 103a-8 passes through the second fixed post 103a-1. A fixed cylinder 103a-5 is movably sleeved on the outer ring of the second fixed post 103a-1. A first groove 103a-6 is opened on the outer ring of the fixed cylinder 103a-5. A protrusion 103a-7 is provided in the first groove 103a-6. The belt 101c is connected to the first driven wheel 102d and the second driven wheel 103a-3 for transmission.

[0039] Furthermore, through the cooperation of belt 101c and second driven wheel 103a-3, the servo motor 101a can realize the rotation of second fixed column 103a-1. The rotation of second fixed column 103a-1 can drive fixed plate 103a-8 to rotate. Since one end of fixed cylinder 103a-5 is fixedly connected to the inner wall of sludge pump 202, fixed cylinder 103a-5 will not rotate with the rotation of second fixed column 103a-1. At the same time, the protrusion 103a-7 can cooperate with elastic element 103b-4. The number of protrusions 103a-7 can be set according to the actual situation.

[0040] The first groove 103a-6 is composed of two semi-threaded grooves. The end of the first groove 103a-6 closer to the second driven wheel 103a-3 is designated as the far end L, and the end farther away from the second driven wheel 103a-3 is designated as the near end K. The dimensions of the far end L and the near end K are lower than the plane of the first groove 103a-6.

[0041] Specifically, the first crushing assembly 103b includes a first sleeve 103b-1 movably sleeved on the outer ring of the second fixed post 103a-1, a plurality of first crushing blades 103b-2 fixedly sleeved on the outer ring of the first sleeve 103b-1, two second sliding grooves 103b-3 formed in the inner ring of the first sleeve 103b-1, and an elastic element 103b-4 disposed in the inner ring of the first sleeve 103b-1. The second sliding grooves 103b-3 are slidably engaged with the fixed plate 103a-8, and the elastic element 103b-4... -4 slides in conjunction with the first chute 103a-6. The first crushing blade 103b-2 can cut larger mud lumps, thereby achieving a crushing effect. The second chute 103b-3 cooperates with the fixed plate 103a-8, and the rotation of the second fixed column 103a-1 can drive the first sleeve 103b-1 to rotate. At the same time, the cooperation between the first chute 103a-6 and the elastic element 103b-4 also realizes the lateral movement of the first sleeve 103b-1.

[0042] The two ends of the first sleeve 103b-1 slide on the outer ring of the second fixed column 103a-1 and the outer ring of the fixed cylinder 103a-5, respectively, which can prevent sludge from entering the interior of the first sleeve 103b-1 and causing the sliding fit between the elastic element 103b-4 and the first sliding groove 103a-6 to fail, thus ensuring the normal operation of the device.

[0043] Specifically, the elastic element 103b-4 includes a mounting cylinder 103b-41 fixed to the inner ring of the first sleeve 103b-1, a placement groove 103b-42 opened in the inner ring of the mounting cylinder 103b-41, a turbine spring piece 103b-43 disposed in the placement groove 103b-42, and a moving column 103b-45 sliding in the inner ring of the mounting cylinder 103b-41. By setting the moving column 103b-45, it can be ensured that when the first sleeve 103b-1 rotates with the second fixed column 103a-1, the moving column 103b-45 slides in the first sliding groove 103a-6, thereby achieving the sliding effect of the first sleeve 103b-1.

[0044] Specifically, one end of the turbine spring 103b-43 is fixedly connected to the first slider 103b-44, and the other end of the turbine spring 103b-43 is fixed to one side of the placement groove 103b-42. The moving column 103b-45 is provided with a third sliding groove 103b-46, and the third sliding groove 103b-46 slides in cooperation with the first slider 103b-44.

[0045] By setting the turbine spring 103b-43 and by sliding the first slider 103b-44 with the third slide groove 103b-46, the tension provided by the turbine spring 103b-43 can ensure that the moving column 103b-45 can be tightly attached to the first slide groove 103a-6, thus ensuring the sliding contact between the two and preventing misalignment during sliding, which would cause the device to malfunction. The third slide groove 103b-46 is threaded.

[0046] When the movable column 103b-45 contacts the protrusion 103a-7, it will move upward along the inner wall of the mounting cylinder 103b-41. The height of the protrusion 103a-7 allows the movable column 103b-45 to impact the first sleeve 103b-1 as it moves upward. After the impact, the surface of the first sleeve 103b-1 will vibrate, which will clean the sludge adhering to the surface of the first sleeve 103b-1 and the first crushing blade 103b-2. At the same time, after the impact, the vibration of the first sleeve 103b-1 will also vibrate the sludge on its surface, which can disperse the sludge and help to separate and crush it. Meanwhile, the turbine spring 103b-43 can help reduce the vibration of the movable column 103b-45, which can provide a certain degree of protection for the movable column 103b-45 and increase its service life.

[0047] When the moving column 103b-45 reaches the far end L or near end K of the first slide groove 103a-6, the tension of the turbine spring plate 103b-43 will cause the moving column 103b-45 to fit tightly against the first slide groove 103a-6. Due to the setting of the turbine spring plate 103b-43 and the existence of a certain gap between the outer ring of the moving column 103b-45 and the inner wall of the mounting cylinder 103b-41, the lateral elasticity of the turbine spring plate 103b-43 itself can buffer the moving column 103b-45, thereby buffering the first sleeve 103b-1 and effectively preventing the first crushing blade 103b-2 from colliding with the second crushing blade 103c-4 and causing damage.

[0048] Specifically, the second crushing component 103c includes a third fixed column 103c-1, two third sealed bearings 103c-2 fixedly sleeved on the outer ring of the third fixed column 103c-1, a second sleeve 103c-3 fixed on the outer ring of the third fixed column 103c-1, a plurality of second crushing blades 103c-4 fixed on the outer ring of the second sleeve 103c-3, and a second gear 103c-5 fixed on one end of the third fixed column 103c-1. The second crushing blades 103c-4 cooperate with the first crushing blades 103b-2. Through the cooperation of the second crushing blades 103c-4 and the first crushing blades 103b-2, the mud is crushed. At the same time, the left and right movement of the first sleeve 103b-1 can prevent mud from sticking in the gaps formed between the plurality of second crushing blades 103c-4 and the plurality of first crushing blades 103b-2.

[0049] In operation, the servo motor 101a provides power, which drives the belt 101c to rotate via the drive wheel 101b. Through the interaction of the belt 101c with the first driven wheel 102d and the second driven wheel 103a-3, the belt 101c simultaneously drives the first fixed column 102a and the second fixed column 103a-1 to rotate. Simultaneously, through the meshing of the first gear 103a-4 and the second gear 103c-5, the third fixed column 103c-1 rotates synchronously. The rotation of the spiral blades 102c agitates the sludge. Meanwhile, the rotation of the second fixed column 103a-1, via the fixed plate 103a-... 8 drives the first sleeve 103b-1 to rotate. The second crushing blade 103c-4 cooperates with the first crushing blade 103b-2 to crush the mud. Through the fixation of the fixed cylinder 103a-5, when the first sleeve 103b-1 rotates, it will drive the elastic element 103b-4 to slide in the first sliding groove 103a-6, realizing the lateral movement of the first sleeve 103b-1. At the same time, through the cooperation between the elastic element 103b-4 and the protrusion 103a-7, the distal end L, and the proximal end K, the sludge is treated and the first sleeve 103b-1 is cleaned by vibration. The first sleeve 103b-1 also has a buffering effect.

[0050] Example 3

[0051] Reference Figures 9-10 This is the third embodiment of the present invention, which is based on the previous two embodiments. This embodiment provides a sludge pump anti-clogging device, which includes an extraction mechanism 200. The extraction mechanism 200 includes a sludge tank 201, a connecting pipe 203, and a sludge pump 202 disposed between the sludge tank 201 and the connecting pipe 203. The two ends of the sludge pump 202 are respectively fixed to one side of the sludge tank 201 and the inlet of the sludge pump 202. An electric valve 204 is provided at one end of the sludge pump 202. A first placement hole 205 and two second placement holes 206 are opened on one side of the sludge pump 202. A processing mechanism 100 is placed in the sludge pump 202. The sludge can be extracted by the sludge pump 202 and the sludge can be transferred by the connecting pipe 203.

[0052] Specifically, the first placement hole 205 is fixedly connected to the outer ring of the first sealed bearing 102b, the two second placement holes 206 are fixedly connected to the outer rings of the second sealed bearing 103a-2 and the third sealed bearing 103c-2 respectively, and the inner wall of the sludge pump 202 is fixedly connected to one end of the fixed cylinder 103a-5. The complete operation of the device can be achieved through the cooperation between the processing mechanism 100 and the connecting pipe 203.

[0053] When in use, the electric valve 204 is opened, allowing the sludge in the sludge tank 201 to enter the connecting pipe 203. The sludge is then processed by the processing mechanism 100 in the connecting pipe 203, allowing it to be smoothly pumped out by the sludge pump 202, preventing the sludge pump 202 from becoming clogged.

[0054] In summary, during use, by simultaneously opening the connecting pipe 203, the electric valve 204, and the servo motor 101a, the sludge in the sludge tank 201 can enter the connecting pipe 203. By opening the servo motor 101a, the servo motor 101a will drive the drive wheel 101b to rotate. The rotation of the drive wheel 101b can drive the first fixed column 102a to rotate through the cooperation of the belt 101c and the first driven wheel 102d. The rotation of the first fixed column 102a can drive the spiral blade 102c to rotate, thereby agitating the sludge. The agitated sludge then passes through the crushing unit 103, which will crush larger sludge lumps. Simultaneously, through the action of the crushing unit 103 on the sludge during operation, the sludge can be smoothly pumped out by the sludge pump 202.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
