Description

Technical Field

[0001] This utility model relates to the field of boiler feedwater pump technology, and in particular to a heat-insulated boiler feedwater pump motor. Background Technology

[0002] The hot water or steam produced in the boiler can directly provide the heat energy needed for industrial production and people's lives. It can also be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. Boilers that provide hot water are called hot water boilers. They are mainly used for domestic purposes, and also have a small number of applications in industrial production. During the use of the boiler, a water pump needs to continuously supply water into it so that it can be heated for use.

[0003] The impeller shaft of existing boiler feedwater pumps is generally connected to the output end of the motor by bolts and flanges. However, connecting the motor and impeller shaft by flanges and bolts complicates the installation and disassembly process of the feedwater pump or motor, increases the emergency repair time of the feedwater pump or motor, and thus increases time and labor costs, indicating room for improvement.

[0004] Therefore, this application proposes a heat-insulated boiler feedwater pump motor to solve the problems in the background art.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

Through the coordinated design between the motor, the water pump, and the fixing mechanism, by disassembling and assembling the limiting rod and sequentially disassembling and assembling the U-shaped locking blocks and rectangular blocks, the output end of the motor and one end of the impeller shaft can be quickly disassembled and assembled, greatly improving convenience and efficiency.

[0011] Preferably, two limiting blocks are installed on the connecting rod, and the two limiting blocks are respectively in contact with the two U-shaped locking blocks. Limiting rods are installed at both ends of the connecting rod, and one end of each of the two limiting rods passes through the two limiting blocks to limit and fix the two U-shaped locking blocks.

[0012] Preferably, slots are provided at both ends of the connecting rod, and the two rectangular blocks are respectively inserted into the two slots to facilitate the connection between the two rectangular blocks and the connecting rod.

[0013] Preferably, each of the two rectangular blocks has a slot, and the connecting rod has two grooves, which correspond to the two slots respectively. The two U-shaped blocks slide in the two grooves and engage with the two slots respectively, so as to facilitate the engagement of the two U-shaped blocks with the two rectangular blocks.

[0014] Preferably, the connecting rod has two threaded grooves, and one end of each of the two limiting rods is threaded.

Through the cooperative design between the motor, feedwater pump, and fixing mechanism, and by disassembling and assembling the limiting rod and the U-shaped locking block and rectangular block in sequence, the output end of the motor and one end of the impeller shaft can be quickly disassembled and assembled, greatly improving convenience and efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] This utility model provides a heat-insulated boiler feedwater pump motor, referring to... Figures 1-4 An insulated boiler feedwater pump motor includes a feedwater pump housing 2 for supplying water to an insulated boiler, a motor 1, and a fixing mechanism 4.

[0027] An impeller shaft 3 is rotatably connected inside the water pump housing 2, and the output end of the motor 1 is connected to one end of the impeller shaft 3 through a fixing mechanism 4;

[0028] The fixing mechanism 4 includes a rectangular block 41, a connecting rod 42, a U-shaped locking block 43, a limiting block 44, and a limiting rod 45. The output end of the motor 1 and one end of the impeller shaft 3 are both fixedly connected to the rectangular block 41. One end of the two rectangular blocks 41 is inserted into the same connecting rod 42. Two U-shaped locking blocks 43 are slidably connected on the connecting rod 42. The two U-shaped locking blocks 43 are respectively engaged with the two rectangular blocks 41. Through the cooperative design between the motor 1, the water pump housing 2, and the fixing mechanism 4, by disassembling and assembling the limiting rod 45 and the U-shaped locking blocks 43 and the rectangular blocks 41 in sequence, the output end of the motor 1 and one end of the impeller shaft 3 can be quickly disassembled and assembled, which greatly improves convenience and efficiency.

[0029] In this embodiment, two limiting blocks 44 are installed on the connecting rod 42. The two limiting blocks 44 are respectively in contact with two U-shaped locking blocks 43. Limiting rods 45 are installed at both ends of the connecting rod 42. One end of the two limiting rods 45 passes through the two limiting blocks 44 respectively, and is used to limit and fix the two U-shaped locking blocks 43.

[0030] In this embodiment, slots 5 are provided at both ends of the connecting rod 42, and two rectangular blocks 41 are respectively inserted into the two slots 5, so as to facilitate the connection between the two rectangular blocks 41 and the connecting rod 42.

[0031] In this embodiment, each of the two rectangular blocks 41 is provided with a slot 6, and the connecting rod 42 is provided with two grooves 7. The two grooves 7 correspond to the two slots 6 respectively. The two U-shaped blocks 43 slide in the two grooves 7 and engage with the two slots 6 respectively, so that the two U-shaped blocks 43 can engage with the two rectangular blocks 41.

[0032] In this embodiment, the connecting rod 42 has two threaded grooves 8, and one end of each of the two limiting rods 45 is threaded. The two threads are adapted to the two threaded grooves 8 respectively. The interaction between the threads and the threaded grooves 8 achieves the effect of limiting the limiting rods 45.

[0033] In this embodiment, through holes are provided on both ends of the two limiting blocks 44 and the connecting rod 42, and are adapted to the two limiting rods 45, so that one end of the two limiting rods 45 can pass through the two limiting blocks 44.

[0034] In this embodiment, the bottom of both the motor 1 and the water pump housing 2 are fixedly connected to mounting bases, which facilitates the fixing of the motor 1 and the water pump housing 2.

[0035] Working principle: In use, firstly, insert the rectangular block 41 at one end of the impeller shaft 3 and the rectangular block 41 at the output end of the motor 1 into the slots 5 at both ends of the connecting rod 42, so that the slots 6 and grooves 7 correspond. Then, insert the two U-shaped blocks 43 into the two grooves 7, so that the two U-shaped blocks 43 engage with the two slots 6 respectively. At this time, through the interaction between the U-shaped blocks 43 and the slots 6, the two rectangular blocks 41 are limited and fixed. Then, through the action of the connecting rod 42, the output end of the motor 1 and one end of the impeller shaft 3 are quickly connected.

[0036] Next, the limiting blocks 44 are installed into the grooves 7 in sequence, so that the through holes on the limiting blocks 44 correspond to the threaded grooves 8. Then, one end of the limiting rod 45 is passed through the limiting blocks 44 and connected to the threaded grooves 8. At this time, the cooperation between the limiting rod 45 and the limiting blocks 44 can achieve the effect of blocking and limiting the two U-shaped blocks 43.

[0037] Conversely, this allows for the quick disassembly of either motor 1 or impeller shaft 3.

[0038] The technological advancements of this invention compared to existing technologies are as follows: the various components enable rapid assembly and disassembly of the motor 1 and the impeller shaft 3, significantly reducing the time required for equipment repair, improving convenience and efficiency, and offering a simpler structure and greater practicality.

[0039] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
