Description

Technical Field

[0001] This invention relates to the field of pump technology, specifically to a high-viscosity pump. Background Technology

[0002] High viscosity pumps are a new type of positive displacement pump developed to meet the needs of industries such as petroleum, chemical, coating, oil, pharmaceutical, dye, and food. Due to the availability of different materials and its unique structure, this product is widely used for conveying media of different properties and viscosities.

[0003] Existing high-viscosity pumps suffer from simple, unstable, and easily damaged sealing structures, resulting in poor sealing performance. Patent CN217761281U, entitled "A High-Viscosity Pump with Improved Sealing Performance," addresses these issues by inserting a first and second sealing gasket into the two ends of an intermediate sealing gasket, forming a multi-layered sealing structure. The ends of the first and second sealing gaskets furthest from the intermediate gasket are then inserted into the pump body. The first and second sealing gaskets secure the multi-layered sealing structure to the pump body. Furthermore, the elasticity of the first, second, and intermediate sealing gaskets enhances their sealing performance through mutual compression, improving the stability of the sealing structure and effectively improving the sealing performance of the high-viscosity pump. This method effectively solves the aforementioned problems.

[0004] However, the materials transported by this type of high-viscosity pump are generally highly viscous. During use, the delivery pipe needs to be disassembled periodically to scrape off the sticky substance adhering to the inside of the pipe. Furthermore, the existing high-viscosity pumps are connected to the delivery pipe via flanges, making disassembly and assembly cumbersome. Also, because the suction force of viscous substances is far greater than that of water, the pump itself is almost immobile without external pushing or pulling, relying solely on its own weight for transport. Each time it transports viscous substances, the internal conveying structure must bear the weight of the viscous substance being transported. This is why high-viscosity pumps are more prone to failure than other types of pumps. Therefore, this design does not meet the current requirements, and we have proposed a new high-viscosity pump. Summary of the Invention

[0005] The purpose of this invention is to provide a high-viscosity pump to solve the problems mentioned in the background art. In the use of such high-viscosity pumps, the materials transported by these pumps generally have high viscosity. During operation, the conveying pipe needs to be periodically removed to scrape off the sticky substance adhering to the inside of the pipe. Furthermore, the existing high-viscosity pumps are connected to the conveying pipe via flanges, making disassembly and assembly cumbersome. Additionally, during the transport of viscous substances, the suction force of the viscous substance is much greater than that of water or other substances. Without external force to push or pull, the pump itself is almost immobile and can only transport the material. Each time the pump is used, its internal conveying structure must bear the weight of the viscous substance being transported, which is why high-viscosity pumps are more prone to failure than other types of pumps.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high viscosity pump, comprising a high viscosity pump body, wherein two flange connecting plates are symmetrically fixed on both sides of the outer surface of the high viscosity pump body, and a conveying pipe is provided on one side of each of the two flange connecting plates, and a guide port is provided at each of the eight end corners of the flange connecting plate facing the conveying pipe, and a threaded fixing rod is fixed inside each guide port.

Each guide sleeve is provided with a threaded connecting rod fixed inside the conveying pipe on one side, and the outer surface of the threaded connecting rod is fitted with an external tooth internal thread sleeve that matches the external thread of both the threaded fixing rod and the threaded connecting rod.

[0008] Each of the two conveying pipes has a viscous conveying mechanism installed on one side inside. The viscous conveying mechanism includes a metal shell that communicates with the interior of the conveying pipe. A transmission gear is installed above the middle position inside the metal shell, and a spur gear meshes above the transmission gear.

[0009] Preferably, an L-shaped pusher is provided between the external toothed internal thread sleeve and the flange connecting plate, located inside the conveying pipe, and a spring is connected to one side of the outer surface of the L-shaped pusher.

[0010] The L-shaped push bracket is connected to a reinforcing block on the side facing the flange connection plate. Both the side of the reinforcing block facing the L-shaped push bracket and the side of the L-shaped push bracket facing the reinforcing block are inclined surfaces. The L-shaped push bracket and the reinforcing block are connected by a guide rail structure.

[0011] Each of the eight corners of the flange connecting plate facing the high viscosity pump body is provided with a reinforcing groove that matches the position of the reinforcing block.

[0012] Preferably, an external toothed sleeve is provided between the eight external toothed internal threaded sleeves, which is installed inside the conveying pipe by a roller bearing and simultaneously meshes with the eight external toothed internal threaded sleeves. One side of the outer surface of the external toothed sleeve is provided with an annular groove for the internal tooth head, and a tooth column is meshed inside the annular groove for the internal tooth head.

[0013] Preferably, the toothed column is connected to a toothed column shaft at its center. One end of the toothed column shaft is fixedly provided with a connector A. One side of the connector A is provided with a connector B. The face of the connector A facing the connector B is provided with a ring of pointed tooth grooves. The face of the connector B facing the connector A is provided with a ring of pointed teeth whose shape matches the pointed tooth grooves.

[0014] Preferably, a roller bearing sleeve is installed at the middle position of the outer surface of the connector B via a roller bearing, and two single-cylinder cylinders, both installed inside the conveying pipe, are symmetrically connected to both sides of the outer surface of the roller bearing sleeve.

[0015] Preferably, a stepper motor is installed inside the conveying pipe on one side of the connector B. The side of the stepper motor facing the connector B is connected to a transmission shaft via a coupling. A square rod is fixedly provided on the side of the transmission shaft facing the connector B, and the top end of the square rod is movably inserted into the interior of the connector B.

[0016] A bevel gear is fixedly fitted at the middle position of the outer surface of the transmission shaft.

[0017] Preferably, the mucus delivery mechanism further includes a bevel gear A, and the bevel gear A is meshed with a conical gear.

[0018] Preferably, the shaft of the bevel gear A is connected to a gear shaft, and a bevel gear shaft is provided on one side of the gear shaft at the middle position of the upper end face of the metal shell, and the gear shaft and the bevel gear shaft are connected in series by a synchronous chain.

[0019] Preferably, a bevel gear B is fixedly sleeved on the lower side of the outer surface of the bevel gear shaft, the bevel gear B meshes with a bevel gear C, and the shaft of the bevel gear C is connected to a spur gear shaft that passes through the shaft of a spur gear.

[0020] Preferably, an arc-shaped cover plate is provided above the stepper motor on the upper end face of the conveying pipe, and the conveying pipe and the arc-shaped cover plate are fixed together by screws.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This invention uses a stepper motor to automatically fix or release the conveying pipe from the flange connection plate, eliminating the need for manual operation during assembly and disassembly, thus making it easier for workers to clean the sticky substances adhering to the inside of the conveying pipe.

[0023] 2. This invention also allows the stepper motor to simultaneously drive the transmission gear to rotate counterclockwise. The viscous material entering the high-viscosity pump body and being discharged by the high-viscosity pump body will come into contact with the counterclockwise rotating transmission gear. When the viscous material comes into contact with the counterclockwise rotating transmission gear, it can be pushed forward. Through the above technical solution, the viscous material can be automatically transported. Thus, during the operation of the high-viscosity pump body, its internal conveying mechanism will only bear the viscous material between the viscous material conveying mechanism and the high-viscosity pump body, thereby reducing the weight borne by the high-viscosity pump body during operation and reducing the possibility of equipment failure.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Please see Figures 1 to 7 An embodiment of the present invention provides a high viscosity pump, comprising a high viscosity pump body 1, characterized in that: two flange connecting plates 2 are symmetrically fixed on both sides of the outer surface of the high viscosity pump body 1, a conveying pipe 5 is provided on one side of each of the two flange connecting plates 2, and a guide port 24 is provided at each of the eight end corners of the flange connecting plate 2 facing the conveying pipe 5, and a threaded fixing rod 4 is fixed inside each guide port 24.

[0034] Each of the eight corners of the face of the conveying pipe 5 facing the flange connection plate 2 is provided with a guide sleeve 25 that matches the position and size of the guide port 24. Each guide sleeve 25 is provided with a threaded connecting rod 6 fixed inside the conveying pipe 5 on one side, and the outer surface of the threaded connecting rod 6 is fitted with an external tooth internal thread sleeve 7 that matches the external threads of the threaded fixing rod 4 and the threaded connecting rod 6.

[0035] When in use, check the condition of each mechanism, move the device to the working area, connect the power supply, align the eight guide sleeves 25 on the outer surface of the conveying pipe 5 with the eight guide ports 24 on the outer surface of the flange connecting plate 2, and insert them. During this process, the threaded fixing rod 4 located inside the guide port 24 will pass through the guide sleeve 25 and enter the interior of the conveying pipe 5.

[0036] Between the eight external toothed internal threaded sleeves 7, there is an external toothed sleeve 12 installed inside the conveying pipe 5 via a roller bearing and simultaneously meshing with the eight external toothed internal threaded sleeves 7. One side of the outer surface of the external toothed sleeve 12 is provided with an internal tooth head annular groove, and one side of the internal tooth head annular groove is meshed with a tooth column 13. The tooth column 13 is connected to the axis of a tooth column shaft 14. One end of the tooth column shaft 14 is fixedly provided with a connector A15. One side of the connector A15 is provided with a connector B17. The surface of the connector A15 facing the connector B17 is provided with a ring of pointed tooth grooves 16. The surface of the connector B17 facing the connector A15 is provided with a ring of pointed teeth 18 whose shape matches the pointed tooth grooves 16. A roller bearing sleeve 19 is installed in the middle position of the outer surface of the connector B17 via a roller bearing. Two single-cylinder cylinders 20, both installed inside the conveying pipe 5, are symmetrically connected to both sides of the outer surface of the roller bearing sleeve 19.A stepper motor 22 is installed inside the conveying pipe 5 on one side of the connector B17. A drive shaft 26 is connected to the side of the stepper motor 22 facing the connector B17 via a coupling. A square rod 21 is fixedly mounted on the side of the drive shaft 26 facing the connector B17, and the top end of the square rod 21 is movably inserted into the connector B17. When the guide sleeve 25 is inserted into the conveying pipe 5, the single-cylinder cylinder 20 is activated, which pushes the connected roller bearing sleeve 19 forward. The movement of connector B17, which is connected to the roller bearing, also causes the movement of connector B17. As connector B17 moves, the pointed tooth 18 on the outer surface of connector B17 will insert into the pointed tooth groove 16 on the outer surface of connector A15. Then, stepper motor 22 is started, which drives the transmission shaft 26 connected to it to rotate. When the transmission shaft 26 rotates, the square rod 21 fixed to it will also rotate. Since one end of the square rod 21 is movably inserted into connector B17, when the square rod 21 rotates, the connector... B17 will also rotate. When connector B17 rotates, connector A15 connected to it will also rotate. When connector A15 rotates, the gear shaft 14 fixed to it and the gear 13 fixedly sleeved on the outer surface of the gear shaft 14 will also rotate. When gear 13 rotates, the outer gear sleeve 12 fixed to it will also rotate. When the outer gear sleeve 12 rotates, the eight external tooth internal thread sleeves 7 meshing with the outer tooth sleeve 12 will also rotate. Through the thread structure, the rotating external tooth internal thread sleeves 7 can be connected to the threaded connecting rod 6. As the external toothed internal threaded sleeve 7 moves toward the threaded fixing rod 4, the external toothed internal threaded sleeve 7 will simultaneously be fitted onto the outer surfaces of the threaded connecting rod 6 and the threaded fixing rod 4. At this time, the external toothed internal threaded sleeve 7 can connect the threaded connecting rod 6, which is fixed to the conveying pipe 5, and the threaded fixing rod 4, which is fixed to the flange connecting plate 2. When it is necessary to release the fixation, the stepper motor 22 can rotate the transmission shaft 26 in the opposite direction. Through the above technical solution, the conveying pipe 5 can be automatically fixed or removed, thereby increasing the convenience of the equipment.

[0037] A bevel gear 23 is fixedly sleeved at the middle position of the outer surface of the transmission shaft 26.

[0038] An L-shaped pusher 8 located inside the conveying pipe 5 is provided between the external toothed internal thread sleeve 7 and the flange connecting plate 2. A spring 11 is connected to one side of the outer surface of the L-shaped pusher 8.

[0039] The L-shaped push bracket 8 is connected to a reinforcing block 9 on the side facing the flange connection plate 2. Both the side of the reinforcing block 9 facing the L-shaped push bracket 8 and the side of the L-shaped push bracket 8 facing the reinforcing block 9 are inclined surfaces, and the L-shaped push bracket 8 and the reinforcing block 9 are connected by a guide rail structure.

[0040] Each of the eight corners of the flange connecting plate 2 facing the high viscosity pump body 1 is provided with a reinforcing groove 10 that matches the position of the reinforcing block 9. When the external tooth internal thread sleeve 7 moves towards the threaded fixing rod 4, it will contact the L-shaped push bracket 8 and push the L-shaped push bracket 8 to move. As the L-shaped push bracket 8 moves, the reinforcing block 9 connected to the guide rail will be pushed inward, so that it is locked into the interior of the reinforcing groove 10 located on the outer surface of the flange connecting plate 2. By locking the reinforcing block 9 into the interior of the reinforcing groove 10, gaps can be effectively prevented between the delivery pipe 5 and the flange connecting plate 2. In the process of releasing the fixing of the delivery pipe 5 and the flange connecting plate 2, the reaction force of the spring 11 squeezed by the L-shaped push bracket 8 during the movement can push the L-shaped push bracket 8 and the reinforcing block 9 connected to it back to their original positions.

[0041] Once the fixing is complete, restart the single-cylinder cylinder 20 to pull connector B17 back to its original position, disconnecting connector A15 from connector B17. After the connection is disconnected, the rotating drive shaft 26 can no longer drive connector A15 to rotate, nor can it release the fixing between the delivery pipe 5 and the flange connecting plate 2.

[0042] A viscous conveying mechanism 3 is installed on one side inside each of the two conveying pipes 5. The viscous conveying mechanism 3 includes a metal housing 305 that communicates with the interior of the conveying pipe 5. A transmission gear 310 is installed above the middle position inside the metal housing 305, and a spur gear 309 meshes above the transmission gear 310.

[0043] The viscous transport mechanism 3 also includes a bevel gear A301, and the bevel gear A301 is meshed with the bevel gear 23. During the rotation of the transmission shaft 26, the bevel gear 23, which is fixedly sleeved on the outer surface of the transmission shaft 26, will also rotate. When the bevel gear 23 rotates, the bevel gear A301 that meshes with it will also rotate.

[0044] A gear shaft 302 is connected to the shaft of the bevel gear A301. A bevel gear shaft 304 is located on one side of the gear shaft 302 at the middle position of the upper end face of the metal housing 305. The gear shaft 302 and the bevel gear shaft 304 are connected in series through a synchronous chain 303. When the bevel gear A301 rotates, the gear shaft 302 connected to the shaft of the bevel gear A301 and the bevel gear shaft 304 connected in series with the gear shaft 302 through the synchronous chain 303 will also rotate.

[0045] A bevel gear B306 is fixedly sleeved on the lower side of the outer surface of the bevel gear shaft 304. The bevel gear B306 meshes with a bevel gear C307. The shaft of the bevel gear C307 is connected to a spur gear shaft 308 that passes through the shaft of the spur gear 309. When the bevel gear shaft 304 rotates, the bevel gear B306 fixedly sleeved on the lower side of the outer surface of the bevel gear shaft 304 and the bevel gear C307 meshing with the bevel gear B306 will also rotate. When the bevel gear C307 rotates, the spur gear shaft 308 connected to the shaft of the bevel gear C307 and the spur gear 309 fixedly sleeved on the outer surface of the spur gear shaft 308 will also rotate. When the spur gear 309 rotates, the transmission gear 310 meshing with it will also rotate.

[0046] The two counterclockwise rotating transmission gears 310 will respectively contact the viscous substance that is about to enter the high viscosity pump body 1 and the viscous substance that is discharged by the high viscosity pump body 1. When the viscous substance contacts the counterclockwise rotating transmission gears 310, it can be pushed forward. Through the above technical solution, the viscous substance can be automatically transported. Thus, during the operation of the high viscosity pump body 1, the internal conveying mechanism will only bear the viscous substance between the viscous conveying mechanism 3 and the high viscosity pump body 1, thereby reducing the weight borne by the high viscosity pump body 1 during operation and reducing the possibility of equipment failure.

[0047] Above the stepper motor 22 is an arc-shaped cover plate located on the upper end face of the conveying pipe 5. The conveying pipe 5 and the arc-shaped cover plate are fixed together by screws. The arc-shaped cover plate can protect the internal structure of the conveying pipe 5.

[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
