[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 1-2 This is the first embodiment of the present invention, which provides a sludge pump anti-clogging device, including an extraction unit 100, which includes a sludge tank 101, a connecting pipe 102 disposed on one side of the sludge tank 101, and a sludge pump 103 disposed at one end of the connecting pipe 102; and an anti-clogging unit 200, which includes a power component 201 installed on one side of the connecting pipe 102, a stirring component 202 disposed inside the connecting pipe 102, and a crushing component 203 disposed on one side of the stirring component 202. The crushing component 203 is located inside the connecting pipe 102. By setting up the anti-clogging unit 200, larger mud blocks and stones can be crushed when the sludge is processed by the sludge pump, thus preventing the sludge pump from clogging.

[0033] Specifically, one end of the connecting pipe 102 is fixed to one side of the sludge tank 101 and is connected to the sludge tank 101. One end of the connecting pipe 102 is equipped with an electric valve 102a, and the other end of the connecting pipe 102 is connected to the sludge pump 103 through a flange. The connecting pipe 102 has a first through hole 102b and two second through holes 102c. The first through hole 102b and the second through holes 102c provide space for the placement of the anti-clogging unit 200 and ensure the normal operation of the anti-clogging unit 200.

[0034] In use, by controlling the power component 201, the stirring component 202 and the crushing component 203 can be turned on and off to crush mud and stones. At the same time, by cooperating with the first crushing component 203a, the curved column 203c and the second crushing component 203b, the movement control of the first crushing component 203a can be realized, so that it crushes mud and stones more thoroughly.

[0035] Example 2

[0036] Reference Figures 3-5This is the second embodiment of the present invention, which differs from the first embodiment in that it also includes a power component 201, which includes a servo motor 201a installed on one side of the connecting pipe 102, a drive wheel 201b fixed to the output end of the servo motor 201a, and a belt 201c disposed on the drive wheel 201b. The drive wheel 201b and the belt 201c are adapted to each other. The servo motor 201a can provide the power required for the operation of the anti-blocking unit 200, and the drive wheel 201b and the belt 201c can realize the transmission effect with the stirring component 202 and the crushing component 203.

[0037] Specifically, the mixing assembly 202 includes a first fixed column 202a, two first sealed bearings 202b sleeved on the outer ring of the first fixed column 202a, a spiral blade 202c fixed on the outer ring of the first fixed column 202a, and a first driven wheel 202d fixedly sleeved on the outer ring of the first fixed column 202a. The first sealed bearings 202b are adapted to the belt 201c. The first driven wheel 202d enables the first fixed column 202a to rotate via the servo motor 201a. At the same time, the spiral blades 202c can stir the sludge when the first fixed column 202a rotates, which can help remove the sludge adhesion problem and ensure smoother sludge removal.

[0038] Specifically, two first sealing bearings 202b are located at both ends of the first fixed column 202a, and the inner ring of the first sealing bearing 202b is fixedly connected to the first fixed column 202a. The outer ring of the first sealing bearing 202b is fixed to the inner ring of the first through hole 102b. The first driven wheel 202d is located outside one of the first sealing bearings 202b and outside the connecting pipe 102. By setting the first sealing bearings 202b, the influence of sludge on the rotation of the first fixed column 202a can be prevented, ensuring the smooth rotation of the first fixed column 202a.

[0039] By changing the shape of the spiral blade 202c, different effects can be achieved when mixing sludge. For example, if the outer ring of the first fixed column 202a is fixed with a traditional stirring rod, it can only be stirred and cannot achieve the effect of diverting sludge. The spiral blade used here can drive the sludge to the middle or both sides in a small range when rotating, which can help the crushing component 203 to crush mud and stones.

[0040] In use, the servo motor 201a is turned on, which drives the drive wheel 201b to rotate. Through the transmission action of the belt 201c, the first driven wheel 202d can be driven to rotate, thereby driving the first fixed column 202a to rotate. When the first fixed column 202a rotates, the sludge can be stirred by the spiral blades 202c, and the sludge that is stuck together can be stirred apart. The sludge that cannot be stirred apart by the spiral blades 202c is crushed by the crushing component 203.

[0041] Example 3

[0042] Reference Figures 6-9 This is the third embodiment of the present invention. Based on the previous two embodiments, this embodiment further includes a crushing component 203, which includes a first crushing element 203a, a second crushing element 203b disposed on one side of the first crushing element 203a, and two curved columns 203c sleeved on the outer ring of the first crushing element 203a. The crushing component 203 is used in conjunction with the power component 201 and the stirring component 202. Through the cooperation of the first crushing element 203a and the second crushing element 203b, the crushing of mud and stones can be achieved, preventing the sludge pump from becoming clogged.

[0043] Specifically, the first crushing component 203a includes a second fixed post 203a-1, two second sealed bearings 203a-2 mounted on the outer ring of the second fixed post 203a-1, a second driven wheel 203a-3 fixed on the outer ring of the second fixed post 203a-1, four sliding strips 203a-5 fixed to the center of the outer ring of the second fixed post 203a-1, and a first gear 203a-4 fixed to one end of the second fixed post 203a-1. The second driven wheel 203a-3 is connected to the belt 20 The first crusher 203a and the second crusher 203b are synchronously rotated through the gear 203a-4. While rotating, they can also produce a certain conveying effect on the sludge. At the same time, the slide bar 203a-5 can drive the rotation of the fixed column 203a-1 to drive the rotation of the fixed sleeve 203a-6. The second sealed bearing 203a-2 can also block the influence of the sludge on the rotation of the second fixed column 203a-1.

[0044] Specifically, the outer ring of the second fixed column 203a-1 is provided with a fixed sleeve 203a-6, and the inner ring of the fixed sleeve 203a-6 is provided with four sliding grooves 203a-7, which slide in cooperation with the sliding strip 203a-5. Multiple first crushing pieces 203a-8 are fixedly connected to the outer ring of the fixed sleeve 203a-6. Fixed rods 203a-9 and elastic rods 203a-10 are fixedly connected to both sides of the fixed sleeve 203a-6 respectively. Through the setting of the first crushing pieces 203a-8, the crushing effect of mud and stone can be achieved. At the same time, the number of first crushing pieces 203a-8 can be set according to the degree of crushing of mud and stone. The sliding grooves 203a-7 enable the fixed sleeve 203a-6 to move when the second fixed column 203a-1 drives the fixed sleeve 203a-6 to rotate.

[0045] Specifically, the second crushing component 203b includes a third fixed column 203b-1 that rotates on the connecting pipe 102 via two third sealed bearings 203b-2, a fixed cylinder 203b-4 fixedly sleeved on the outer ring of the third fixed column 203b-1, a plurality of second crushing plates 203b-5 fixed on the outer ring of the fixed cylinder 203b-4, and a second gear 203b-3 fixed to one end of the third fixed column 203b-1. The second gear 203b-3 meshes with the first gear 203a-4, and the second crushing plates 203b-5 cooperate with the first crushing plates 203a-8. The second crushing plates 203b-5 and the first crushing plates 203a-8 are alternately arranged, and when the first crushing plates 203a-8 move, they can crush the mud more thoroughly. At the same time, the alternating arrangement also prevents mud from sticking to the gaps between the plurality of first crushing plates 203a-8.

[0046] Specifically, one side of the curved column 203c is fixed to the inner wall of the connecting pipe 102. A ring 203c-1 is fixedly connected to the curved side of one of the curved columns 203c. One side of the ring 203c-1 is slidably engaged with the fixed rod 203a-9. The curved surface of the other curved column 203c is slidably engaged with the elastic rod 203a-10. Through the setting of the ring 203c-1, when the fixed sleeve 203a-6 rotates with the second fixed column 203a-1, it can move by cooperating with the fixed rod 203a-9 and the elastic rod 203a-10, so as to ensure more thorough crushing of mud and stones.

[0047] Furthermore, the two ends of the ring 203c-1 are set as a high end L and a low end K. The low end K is lower than the bottom of the curved surface of the curved column 203c. There is a gap between the high end L and the side of the curved column 203c that is close to it. The ring 203c-1 is elastic, and the high end L can move due to compression. The interface between the high end L and the low end K is set at the position where the first crushing piece 203a-8 is about to collide with the second crushing piece 203b-5 during the movement.

[0048] As attached Figure 10 As shown, when the fixed rod 203a-9 slides on one side of the ring 203c-1, for example, when the fixed rod 203a-9 starts to rotate from the bottom end K, the elastic rod 203a-10 is in the extended state. As the fixed sleeve 203a-6 rotates, it drives the fixed rod 203a-9 and the elastic rod 203a-10 to move. At this time, each first crushing piece 203a-8 will move between the gaps formed by two adjacent second crushing pieces 203b-5. When the fixed rod 203a-9 slides around the ring 203c-1 and slowly rotates... When the first crushing disc 203a-8 reaches the high end L, it moves to the side of the second crushing disc 203b-5. At the same time, the elastic rod 203a-10 is slowly compressed to a contracted state. When it is about to reach the side of the second crushing disc 203b-5, the high end L and the elastic rod 203a-10 will buffer the movement of the fixed sleeve 203a-6, preventing the first crushing disc 203a-8 and the second crushing disc 203b-5 from colliding and avoiding damage to the first crushing disc 203a-8 and the second crushing disc 203b-5.

[0049] When the fixing rod 203a-9 rotates from the high end L to the low end K, since the low end K is lower than the bottom of the curved surface of the curved column 203c, the elastic rod 203a-10 rebounds, which will produce a corresponding vibration effect on the fixing sleeve 203a-6. The vibration effect can clean the sludge adhering to the fixing sleeve 203a-6. Secondly, when the fixing rod 203a-9 rotates from the high end L to the low end K, the high end L will rebound due to the loss of pressure from the fixing rod 203a-9. The high end L will produce a slight vibration when it rebounds, which will achieve a cleaning effect on itself and prevent adhesion. At the same time, a protective ring is set on the outer ring of the ring 203c-1 to prevent sludge from entering the gap between the high end L and the curved column 203c, thus avoiding the failure of the ring 203c-1.

[0050] After the first stirring by the spiral blade 202c, when larger sludge lumps reach one side of the fixed sleeve 203b-1, the suction of the sludge pump 103 will cause them to stick tightly to one side of the fixed sleeve 203a-6. At this time, the larger sludge lumps cannot pass through. However, by moving the fixed sleeve 203a-6, the sludge lumps sticking to one side of the fixed sleeve 203a-6 can be continuously broken down into smaller sludge lumps that can pass between the fixed sleeve 203a-6 and the fixed cylinder 203b-4. At the same time, the first crushing blade 203a-8 and the second crushing blade 203b-5 crush them, which can solve the problem of large sludge lumps blocking one side of the fixed sleeve 203a-6.

[0051] The sludge and stones are crushed by the first crushing plate 203a-8 and the second crushing plate 203b-5. After crushing, the crushed sludge and stone particles will mix together, causing the sludge to become locally viscous and stick to the first crushing plate 203a-8 and the second crushing plate 203b-5. By moving the fixed sleeve 203a-6, not only can the sludge and stones be crushed more finely, but the movement of both can also push the sludge, causing the sludge to flow in a wave-like manner. This can achieve a localized mixing effect on the sludge, making the sludge consistency more uniform in all places after passing through the fixed sleeve 203a-6, making the sludge pumping smoother.

[0052] In use, the belt 201c and the second driven wheel 203a-3 cooperate to make the belt 201c drive the second driven wheel 203a-3 to rotate. The rotation of the second driven wheel 203a-3 can drive the second fixed column 203a-1 to rotate. At this time, due to the sliding cooperation between the slide bar 203a-5 and the slide groove 203a-7, the rotation of the second fixed column 203a-1 can drive the fixed sleeve 203a-6 to rotate. The rotation of the fixed sleeve 203a-6 can drive the first crushing piece 203a-8 to rotate. When the first crushing piece 203a-8 rotates, it can drive the fixed rod 203a-9 to rotate. The rotation of the fixed rod 203a-9 will move according to the setting of the curved surface of the curved column 203c, realizing that the fixed sleeve 203a-6 rotates and moves at the same time.

[0053] In summary, during use, the sludge pump 103, electric valve 102a, and servo motor 201a are simultaneously turned on. The sludge pump 103 extracts sludge through the connecting pipe 102. During the extraction process, the servo motor 201a drives the drive wheel 201b to rotate. Through the transmission action of the belt 201c, the first driven wheel 202d and the second driven wheel 203a-3 can be driven to rotate, thereby driving the first fixed column 202a to rotate. When the first fixed column 202a rotates, the sludge can be stirred by the spiral blades 202c. The second driven wheel 201a... The rotation of 3a-3 can drive the second fixed column 203a-1 to rotate. At this time, due to the sliding engagement between the slide bar 203a-5 and the slide groove 203a-7, the rotation of the second fixed column 203a-1 can drive the fixed sleeve 203a-6 to rotate. The rotation of the fixed sleeve 203a-6 can drive the first crushing piece 203a-8 to rotate. When the first crushing piece 203a-8 rotates, it can drive the fixed rod 203a-9 to rotate. The rotation of the fixed rod 203a-9 will move according to the curved surface setting of the curved column 203c, realizing the movement of the fixed sleeve.

[0054] When 203a-6 rotates, it moves back and forth. Since the curved columns 203c set on the two second fixed columns 203a-1 are different, the two fixed sleeves 203a-6 will move in an alternating manner, which ensures the crushing of mud and stones.

[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.
