Description

Technical Field

[0001] This utility model relates to the field of centrifugal pump technology, and in particular to a cooling barrier for a centrifugal pump. Background Technology

[0002] Centrifugal pumps work by using the rotation of an impeller to cause water to move in a centrifugal motion. They consist of an impeller, a pump casing, and a shaft seal. Material is loaded into the centrifugal pump, and then the motor is started, causing the pump shaft to drive the impeller and the material to rotate at high speed. The centrifugal force generated by the high-speed rotation of the impeller causes the material to move in a centrifugal motion, throwing the liquid from the center of the impeller to the outer edge of the impeller, thereby realizing the liquid transportation.

[0003] A search revealed Chinese Patent Publication No. CN218266480U, which discloses a centrifugal pump sealing device and a centrifugal pump. The device includes a mounting plate with a centrifugal pump motor and a centrifugal pump housing mounted on its top two sides. A rotating shaft is connected to the output end of the centrifugal pump motor, with one side of the shaft penetrating inside the centrifugal pump housing and an impeller connected to it. A sealing mechanism is provided on one side of the outer wall of the rotating shaft. This invention features a sealing mechanism where a telescopic spring, through its restoring deformation force, drives a moving ring to the right, ensuring the sealing ring remains tightly against the connecting ring and the moving ring. This maintains a seal between the rotating shaft and the centrifugal pump housing, preventing leakage due to gaps caused by seal ring wear and ensuring the centrifugal pump's sealing performance. A return spring, through its own restoring deformation force, moves a pressure plate closer to the sealing ring, compressing it and making the sealing ring fit more closely to the rotating shaft surface, increasing the sealing effect. However, in actual use, the rotating shaft drives the sealing ring to rotate, generating a large amount of heat, which can affect the sealing ring and its service life. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a cooling barrier for a centrifugal pump, aiming to improve the problem in the prior art where the rotating shaft drives the sealing ring to rotate, generating a large amount of heat, which affects the sealing ring and reduces its service life.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cooling barrier for a centrifugal pump, comprising a base plate, two support blocks fixedly connected to the top left side of the base plate, a motor fixedly connected to the top of each of the two support blocks, a connecting plate fixedly connected to the right side of the motor, a circular hole opened on the left side of the connecting plate, the output end of the motor passing through the left side of the circular hole, a semi-circular groove opened inside the circular hole, a sealing ring fixedly connected to the output end of the motor, and a stirring blade fixedly connected to the output end of the motor, a base plate fixedly connected to the right side of the connecting plate, a cap fixedly connected to the right side of the connecting plate, a feed pipe connected to the top of the cap, bolts threaded around the right side of the cap, and the left sides of multiple bolts passing through the cap and threadedly connected to the connecting plate, a cooling pipe fixedly connected to the left side of the connecting plate, valves fixedly connected to the front and rear sides of the cooling pipe, and a fixing mechanism provided on the left side of the connecting plate.

[0006] Through the above technical solution: after the motor starts, the output end passes through the round hole of the connecting plate, driving the stirring blade to rotate and achieve the stirring function. At the same time, the output end drives the sealing ring to rotate in the semi-circular groove, thereby increasing the sealing performance and preventing material leakage. The material enters the cap through the feed pipe and is then stirred by the stirring blade. During operation, the friction between the motor output end and the sealing ring generates a large amount of heat. To avoid affecting the life of the sealing ring, cooling water is injected into the cooling pipe to cool the left side of the connecting plate, indirectly cooling the sealing ring. The valves on the front and rear sides of the cooling pipe can prevent the cooling water from flowing out, maintain the normal operation of the cooling system, and ensure that the entire device can stably and efficiently complete the material stirring work.

[0007] As a further description of the above technical solution:

[0008] The fixing mechanism includes a fixing ring, the right side of which is fixedly connected to the left side of the connecting plate. Connecting strips are fixedly connected to the front and rear ends of the left side of the fixing ring. Fixing blocks are fixedly connected to the bottom of the two connecting strips. Threaded holes are opened on the top of the two fixing blocks. Bolts are threaded into the interior of the two threaded holes. The bottoms of the two bolts penetrate the threaded holes and are threadedly connected to the right side of the outer wall of the motor.

[0009] Through the above technical solution: the fixing ring is connected to the fixing block by means of the downward extending connecting strip, so that the connection structure is expanded from a plane to a three-dimensional structure, greatly increasing the stability. The threaded hole at the top of the fixing block is connected to the bolt. After the bolt passes through, it is fastened to the outer wall of the motor, so that the fixing block and the motor are tightly connected. It is also connected to the connecting plate through the connecting strip and the fixing ring. The vibration and torque generated by the motor operation increase the stability of the connecting plate.

[0010] As a further description of the above technical solution:

[0011] A hinge is fixedly connected to the top rear side of the outer wall of the feed pipe, and a cover plate is fixedly connected to the top front side of the hinge.

[0012] The above technical solution involves a hinge at the top rear side of the outer wall of the feed pipe, which connects to the upper cover plate, allowing the cover plate to be opened and closed flexibly, effectively preventing debris from entering the feed pipe.

[0013] As a further description of the above technical solution:

[0014] A clip fastener is fixedly connected to the top front side of the feed pipe, and a pipe clamp is fixedly connected to the front side of the cover plate.

[0015] The above technical solution allows the buckle fastener at the top front of the feed pipe to work in conjunction with the pipe clamp at the front of the cover plate, ensuring a tight seal and further enhancing the protective effect.

[0016] As a further description of the above technical solution:

[0017] Each of the caps has a gasket fixedly connected to its left side, and each of the gaskets has a smooth design.

[0018] The above technical solution involves fixing a smoothly designed gasket on the left side of each cap to prevent the bolts from being tightened too much, thus ensuring the rationality and safety of the component connection.

[0019] As a further description of the above technical solution:

[0020] Support columns are fixedly connected to the four corners of the bottom of the base plate, and anti-slip sleeves are fixedly connected to the bottom of each of the support columns.

[0021] The above technical solution involves fixing support columns at the four corners of the bottom of the base plate, and installing anti-slip sleeves at the bottom of each support column. This effectively prevents the device from moving when it is started, ensuring its stable position during operation.

[0022] As a further description of the above technical solution:

[0023] The bottom front and rear sides of the connecting plate are provided with mounting holes, and bolts are threaded into the interior of both mounting holes.

[0024] The above technical solution involves mounting holes on the front and rear sides of the bottom of the connecting plate. By threading bolts into the mounting holes, the connecting plate can be securely installed.

[0025] As a further description of the above technical solution:

[0026] The cooling pipe is provided with connecting rings on both the front and rear sides, and the right sides of the two connecting rings are fixedly connected to the left side of the connecting plate.

[0027] The above technical solution involves connecting rings on the front and rear sides of the cooling pipe. The right side of the connecting ring is fixed to the left side of the connecting plate, which can fix the position of the cooling pipe and ensure that it does not shift during operation, thus maintaining normal cooling function.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the friction between the motor output end and the sealing ring generates a large amount of heat.

In this utility model, the fixing ring is connected to the fixing block by means of a downwardly extending connecting strip, which expands the connection structure from a plane to a three-dimensional structure, greatly increasing the stability. The threaded hole at the top of the fixing block is connected to the bolt. After the bolt passes through, it is fastened to the outer wall of the motor, so that the fixing block and the motor are tightly connected. It is also connected to the connecting plate through the connecting strip and the fixing ring.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of a cooling barrier for a centrifugal pump, comprising a base plate 1. Two support blocks 3 are fixedly connected to the top left side of the base plate 1, and the same motor 4 is fixedly connected to the top of each of the two support blocks 3. The support blocks 3 support the motor 4. A connecting plate 5 is fixedly connected to the right side of the motor 4. A circular hole 6 is opened on the left side of the connecting plate 5, and the output end of the motor 4 passes through the left side of the circular hole 6. A semi-circular groove 7 is opened inside the circular hole 6. A sealing ring 8 is fixedly connected to the output end of the motor 4. When the output end of the motor 4 rotates inside the circular hole 6, it will drive the sealing ring 8 to rotate inside the semi-circular groove 7. The sealing ring 8 is used to increase the sealing performance. An agitator 9 is fixedly connected to the output end of the motor 4. The rotation of the motor 4 drives the agitator 9 to rotate. The base plate 1 is fixedly connected to the right side of the connecting plate 5. A cap 10 is connected, and a feed pipe 11 is connected to the top of the cap 10 for feeding. Bolts 12 are threaded around the right side of the cap 10. The left side of the multiple bolts 12 passes through the cap 10 and is threaded to the connecting plate 5. The cap 10 is fixed to the right side of the connecting plate 5 by the bolts 12. A cooling pipe 13 is fixedly connected to the left side of the connecting plate 5. When the output end of the motor 4 drives the sealing ring 8 to rotate inside the semi-circular groove 7, a lot of heat will be generated, which will affect the sealing ring 8 and affect its service life. The cooling pipe 13 cools the left side of the connecting plate 5 by adding cooling water, thereby cooling the sealing ring 8. Valves 14 are fixedly connected to the front and rear sides of the cooling pipe 13 to prevent the cooling water inside the cooling pipe 13 from flowing out. A fixing mechanism 2 is provided on the left side of the connecting plate 5.

[0041] Specifically, the base plate 1 serves as a basic support, with two support blocks 3 fixed to its top left side, supporting the motor 4 above. A connecting plate 5 is connected to the right side of the motor 4. A circular hole 6 on the left side of the connecting plate 5 provides a passage for the output end of the motor 4. A semi-circular groove 7 is formed inside the circular hole 6, which cooperates with the sealing ring 8 fixedly connected to the output end of the motor 4. When the motor 4 operates, its output end rotates within the circular hole 6, and the sealing ring 8 rotates accordingly within the semi-circular groove 7, effectively increasing the sealing performance of the device and preventing liquid or gas leakage. The output end of the motor 4 is also connected to a stirring blade 9. The rotation of the motor 4 drives the stirring blade 9 to rotate synchronously, thereby achieving the stirring function. A cap 10 is fixedly connected to the right side of the connecting plate 5, and the top... The connected feed pipe 11 provides a convenient channel for material input. The cap 10 is securely fixed to the right side of the connecting plate 5 by multiple bolts 12 connected by threads around its right side, ensuring the tightness and stability of the connection. Since the motor 4 output end drives the sealing ring 8 to rotate in the semi-circular groove 7, a large amount of heat will be generated. If this heat is not dissipated in time, it will seriously affect the service life of the sealing ring 8. The cooling pipe 13 can effectively cool the left side of the connecting plate 5 by injecting cooling water, thereby indirectly cooling the sealing ring 8 and ensuring its normal operation. The valves 14 fixedly connected to the front and rear sides of the cooling pipe 13 can effectively prevent the cooling water in the cooling pipe 13 from flowing out, ensuring the normal operation of the cooling system.

[0042] Reference Figure 5 and Figure 6 The fixing mechanism 2 includes a fixing ring 201. The right side of the fixing ring 201 is fixedly connected to the left side of the connecting plate 5. The front and rear ends of the left side of the fixing ring 201 are fixedly connected to connecting strips 202. The bottom of the two connecting strips 202 is fixedly connected to fixing blocks 203. The top of the two fixing blocks 203 is provided with threaded holes 204. The inside of the two threaded holes 204 is threaded with bolts 205. The bottom of the two bolts 205 passes through the threaded holes 204 and is threadedly connected to the right side of the outer wall of the motor 4. The fixing blocks 203 are fixed to the front and rear ends of the right side of the motor 4 by the bolts 205 to increase the stability of the connecting plate 5.

[0043] Specifically, the right side of the fixing ring 201 and the left side of the connecting plate 5 are fixed, and the front and rear ends of the left side are respectively connected to the connecting strips 202. These two connecting strips 202 extend downward and are connected to the fixing block 203 at the bottom. The top of the fixing block 203 has a threaded hole 204, into which the bolt 205 is screwed. The bottom passes through the threaded hole 204 and is threaded to the right side of the outer wall of the motor 4. Through the tightening action of the bolt 205, the fixing block 203 is firmly fixed to the front and rear ends of the right side of the motor 4, tightly connecting the connecting plate 5 and the motor 4. When the motor 4 is running, this structure can effectively reduce the shaking and displacement of the connecting plate 5, greatly enhance its stability, and ensure that the centrifugal pump is tightly connected and operates reliably when it is working.

[0044] Reference Figure 1 and Figure 3 A hinge 15 is fixedly connected to the top rear side of the outer wall of the feed pipe 11. A cover plate 16 is fixedly connected to the top front side of the hinge 15 to prevent foreign objects from entering the feed pipe 11. A buckle fastener 17 is fixedly connected to the top front side of the feed pipe 11. A pipe clamp 18 is fixedly connected to the front side of the cover plate 16 to tighten the cover plate 16. A gasket 19 is fixedly connected to the left side of each of the multiple caps 10. The multiple gaskets 19 are all designed with a smooth shape to prevent the bolts 12 from being tightened.

[0045] Specifically, the hinge 15 on the top rear side of the outer wall of the feed pipe 11 is connected to the cover plate 16 above, which can flexibly open and close the cover plate 16 to effectively prevent foreign objects from entering the feed pipe 11. The buckle fastener 17 on the top front side of the feed pipe 11 and the pipe clamp 18 on the front side of the cover plate 16 cooperate with each other to tightly close the cover plate 16, further enhancing the protective effect. Multiple caps 10 are fixed with smooth-designed gaskets 19 on the left side, which prevent the bolts 12 from being tightened too much and ensure the rationality and safety of the component connection.

[0046] Reference Figure 2 , Figure 4 and Figure 5 Support columns 20 are fixedly connected to the four corners of the bottom of the base plate 1. Anti-slip sleeves 21 are fixedly connected to the bottom of the multiple support columns 20 to prevent the device from moving when it is started. Mounting holes 22 are opened on the front and rear sides of the bottom of the connecting plate 5. Bolts 23 are threaded into the interior of the two mounting holes 22 for mounting the connecting plate 5. Connecting rings 24 are provided on the front and rear sides of the cooling pipe 13. The right side of the two connecting rings 24 is fixedly connected to the left side of the connecting plate 5 to fix the position of the cooling pipe 13.

[0047] Specifically, support columns 20 are fixed at the four corners of the bottom of the base plate 1, and anti-slip sleeves 21 are installed at the bottom of each support column 20. This can effectively prevent the device from moving when it is started and ensure its stable position during operation. The bottom of the connecting plate 5 has mounting holes 22 on the front and rear sides. The connecting plate 5 can be securely installed by connecting bolts 23 through the threaded connection in the mounting holes 22. The cooling pipe 13 has connecting rings 24 on the front and rear sides. The right side of the connecting ring 24 is fixed to the left side of the connecting plate 5, which can fix the position of the cooling pipe 13 and ensure that it does not move during operation and maintains normal cooling function.

[0048] Working principle: After the motor 4 starts, the output end passes through the round hole 6 of the connecting plate 5, driving the stirring blade 9 to rotate to achieve the stirring function. At the same time, the output end drives the sealing ring 8 to rotate in the semi-circular groove 7, thereby increasing the sealing performance and preventing material leakage. The material enters the cap 10 through the feed pipe 11 and is then stirred by the stirring blade 9. During operation, the friction between the output end of the motor 4 and the sealing ring 8 generates a lot of heat. In order to avoid affecting the life of the sealing ring 8, cooling water is injected into the cooling pipe 13 to cool the left side of the connecting plate 5, indirectly cooling the sealing ring 8. The valves 14 on the front and rear sides of the cooling pipe 13 can prevent the cooling water from flowing out, maintain the normal operation of the cooling system, and ensure that the entire device can stably and efficiently complete the material stirring work.

[0049] Furthermore, the fixing ring 201 is connected to the fixing block 203 below, and the connecting strip 202 extends downward and connects to the fixing block 203, so that the entire connection structure extends from the plane to the three-dimensional space, enhancing the stability of the structure. The threaded hole 204 opened at the top of the fixing block 203 forms a threaded connection with the bolt 205. The bottom of the bolt 205 passes through the threaded hole 204 and is threadedly connected to the right side of the outer wall of the motor 4. The fixing block 203 is tightly connected to the motor 4 through the bolt 205, and at the same time, it is connected to the connecting plate 5 through the connecting strip 202 and the fixing ring 201. When the motor 4 is running, the motor 4 will generate vibration and torque. If the connection between the connecting plate 5 and the motor 4 is not stable enough, the connecting plate 5 will shake and shift due to the vibration and torque of the motor 4. By tightly combining the connecting plate 5 and the motor 4 into a whole, the force of the motor 4 on the connecting plate 5 can be evenly distributed. The connecting strip 202 and the fixing ring 201 can bear and distribute the torque, preventing the connecting plate 5 from twisting or shifting due to the torque.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
