Description

Technical Field

[0001] The utility model provides a booster pump, belongs to the technical field of urea condenser equipment, and particularly relates to a booster pump for a urea condenser which is easy to disassemble and assemble. Background Art

[0002] In industrial production, optimizing circulating water systems is crucial for improving equipment efficiency and stability. This is especially true in the chemical and energy industries, where the efficient operation of heat exchange equipment such as condensers is crucial to the entire production process. Condensers in the urea production process, such as ammonia condensers and medium-pressure condensers, are typically cooled with circulating water. Because medium-pressure condensers handle high-concentration solutions, directly using low-temperature circulating water for cooling could cause crystallization and blockage on the media side, impacting normal equipment operation. Therefore, a series connection is often used, with the circulating water initially cooling through one heat exchanger before entering another for further cooling.

[0003] However, this design can result in excessively long circulating water pipes, numerous U-bends, and excessive pipe resistance due to the equipment's installation location, which can reduce the circulating water flow rate. Furthermore, if the device is located at the end of the circulating water network, the heat exchanger's circulating cooling water flow rate may be too slow, leading to scaling and impurity accumulation and blockage, seriously affecting the device's high-load, long-term operation.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are for illustrative purposes only and do not represent the only implementation method.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains; the terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention; the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0027] like Figure 1 and Figure 2As shown, a booster pump for a urea condenser that is easy to disassemble and assemble includes a pipeline 1, a boosting structure 2 corresponding to the pipeline 1 is provided inside the pipeline 1, a movable plate 14 corresponding to the boosting structure 2 is provided on one side of the pipeline 1, a pair of locking hoops 15 corresponding to the movable plate 14 are sleeved on the outside of the pipeline 1, and a rubber seal is provided on the side of the movable plate 14 close to the pipeline 1. The boosting structure 2 includes a plurality of stacked centrifugal disks 21 corresponding to the pipeline 1, a cluster disk 22 is located above the centrifugal disk 21 and opposite to the centrifugal disk 21, a drive shaft 11 is provided in the cluster disk 22 that passes through the cluster disk 22 and is fixedly connected to the centrifugal disk 21, a drive motor 12 located inside the pipeline 1 is connected below the drive shaft 11, and a one-way valve 13 is connected to the other end of the drive shaft 11.

[0028] In this embodiment, the water body is pressurized and transported upward by setting a boosting structure 2 inside the pipeline 1. The centrifugal force applied to the water body is increased by means of the multi-layer centrifugal disk 21, thereby increasing the flow rate of the water body, and the clustering disk 22 is used to limit the flow direction of the water body to ensure that it enters the next-level centrifugal disk 21 stably. The one-way valve 13 ensures that the water body does not flow back. The multi-layer stacked boosting structure reduces the occupied plane space, so that it can be effectively placed inside the pipeline 1, which is convenient for direct disassembly and assembly.

[0029] It should be noted that the end of the connecting shell 28 close to the pipe 1 is inserted into the interior of the pipe 1 through a protrusion toward the inside of the pipe 1, thereby ensuring that the installation is sufficiently stable. At the same time, different numbers of centrifugal discs 21 and cluster discs 22 can be added according to the required lifting height, which has strong flexibility and high adaptability.

[0030] like Figure 3 、 4 As shown in Figure 5, the outside of the clustering disc 22 is fixedly connected to an inner shell 23 that is sleeved on the outside of the centrifugal disc 21. A T-shaped limiter 24 is fixedly connected to one side of the inner shell 23. A limit groove 25 corresponding to the limiter 24 is provided on the other side of the inner shell 23. The lower part of the inner shell 23 is connected to a clamping ring 27 sleeved on the outside of the drive motor 12 through a sieve plate 26 corresponding to itself. The upper part of the inner shell 23 and the lower part of the clamping ring 27 are both movably connected to a connecting shell 28 corresponding to the pipeline 1. The one-way valve 13 includes a piston plate 16 having a diameter larger than the inner diameter of the inner shell 23. The upper part of the piston plate 16 is provided with a plurality of cams. The connecting rod 17 is fixedly connected to the side, and the outside of the connecting rod 17 is connected to the blocking plate 19 which is sleeved on the outside of itself and fixedly connected to the corresponding connecting shell 28 through a spring 18. The outside of the drive motor 12 is sleeved with a sealing shell 29 corresponding to the clamping ring 27. The centrifugal disk 21 is provided with spirally diffused fan blades, and a first through groove 211 is formed between the fan blades. The clustering disk 22 is provided with evenly distributed notches that pass through itself, and the notches and the inner shell 23 together form a through hole 212. The clustering disk 22 is provided with evenly distributed fan-shaped partition plates, and second through grooves 213 are formed between the partition plates.

[0031] In this embodiment, when the driving motor 12 starts to rotate, it drives the centrifugal disc 21 to rotate, and the clustering disc 22 mounted on the driving shaft 11 does not rotate. After the water flows into the inside of the pipe 1, when the water flows accumulate on the centrifugal disc 21, the water flow will be rolled up by the fan blades, and under the action of centrifugal force, it will enter the second through groove 213 through the through hole 212 along the first through groove 211 and be ready to contact the centrifugal disc 21 next time. After multiple centrifugal accelerations of the centrifugal disc 21 and the limiting accelerations of the clustering disc 22, the fast-flowing water will push the piston plate 16 away and compress the spring 18 between the piston plate 16 and the connecting rod 17. When the pressure on the bottom side of the piston plate 16 is insufficient, the piston plate 16 will reset under the action of the spring 18 to prevent the water from flowing back.

[0032] It should be noted that multiple inner shells 23 are movably connected with the help of limit members 24 and limit grooves 25. The specific connection method is that there is a larger opening on the limit groove 25 to accommodate the limit member 24 as a whole. After the limit member 24 enters, the two adjacent inner shells are rotated so that the limit member 24 enters deep into the limit groove 25 to achieve connection. At the same time, the connecting shell 28 and the clamping ring 27 are connected by this method or other connection methods with the same effect under the existing technology; water flows into the interior of the inner shell 23 through the sieve plate 26, and the sealed shell 29 ensures the waterproof performance of the drive motor 12. Similarly, the movable plate 14 is simply squeezed on the pipe 1 by the locking hoop 15 with the help of a rubber seal, or a sealed connection is achieved by other methods. This technology is conceivable by those skilled in the art and has nothing to do with the protection point of the utility model, so it will not be described in detail; at the same time, the diameter of the inner shell 23 is slightly larger than that of other plates and is close to the inner wall of the pipe 1.
