Description

Technical Field

[0001] The utility model relates to the technical field of electric boilers, in particular to a silencing device for a water supply pump of an electric boiler. Background Art

[0002] Boiler feed pumps can deliver high-temperature clean water below 280°C, and are suitable for boiler feed, factory and city water supply. Suitable for delivering clean water below 110°C or other non-corrosive liquids with physical and chemical properties similar to water, and widely used in boiler feed of industrial and mining enterprises and urban life water supply. Especially suitable for boiler feed, it can also be widely used in pressure vessel water supply, hot water circulation, high-rise building water supply, farmland irrigation, fire boosting, hydraulic flushing, food, brewing.

[0003] After searching, it is found that a Chinese patent document discloses a silencer for an electric boiler feed pump [application number: CN202123027452.3]. This silencer for an electric boiler feed pump includes a base and a soundproof cover. There are two soundproof covers, which are symmetrically installed at the front and rear ends of the upper surface of the base. The right ends of the two soundproof covers are provided with heat dissipation ports, and the left end of the inside of the heat dissipation port is embedded with a first heat dissipation fan. The right end face of the heat dissipation port is provided with a sealing plate that can move left and right. The right ends of the inner sides of the two soundproof covers are provided with heat dissipation grooves, and the inner ends of the heat dissipation grooves are embedded with heat conduction plates, and the inner sides of the heat conduction plates are bonded with heat conductive silicone blocks. The two heat conductive silicone blocks can be used to soundproof the motor of the boiler feed pump and dissipate heat from the motor. The heat dissipation ports allow the hot air inside the soundproof cover to be discharged to the outside of the soundproof cover at regular intervals.

[0004] When the device disclosed in the patent is in use, the noise generated by the water pump during use can be absorbed by the soundproof cover, so as to reduce the noise. However, the noise generated by the water pump during use is generally the sound of its own rotation and the noise generated by the shaking due to the unstable installation. Although the device has the effect of silencing, the silencing method is relatively single and the silencing effect is not good. The water pump will continue to generate noise during use.

[0005] At the same time, the motor part of the water pump will generate heat when in use. The device can dissipate heat for the water pump when in use. However, the space inside the sound insulation cover is large. When the water pump generates heat, the heat will fill the entire sound insulation cover, causing the device to consume a lot of time in dissipating heat, thus affecting the heat dissipation effect of the device on the water pump.

DETAILED DESCRIPTION

[0021] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0022] See also Figure 1-4As shown, a silencer device for an electric boiler feed water pump comprises a base 1, a connecting plate 2 is fixedly connected to the top of the base 1, a connecting groove 3 is provided on the surface of the connecting plate 2, and the water pump can be separated under the cooperation of the connecting groove 3 and the connecting plate 2, so that the motor part can be separated from the impeller part, a connecting groove 4 is provided on the surface of the connecting plate 2, the number of the connecting grooves 4 is four, and two groups of two are symmetrically distributed, protective shells 5 are provided on both sides of the connecting plate 2, and guide blocks 6 are fixedly connected to two places on one side of the protective shell 5, the surface of the guide block 6 is slidably connected to the inner wall of the connecting groove 4, and the guide block 6 is used in conjunction with the connecting groove 4, under this action, the two places of the water pump can be separated and protected, so that the water pump is isolated in two spaces, a blocking plate 7 is fixedly connected to one side of the protective shell 5, and one side surface of the blocking plate 7 is slidably connected to the inner wall of the connecting groove 3, under this action, the two spaces can be further blocked after the water pump is installed, and the air circulation between the two protective shells 5 is reduced, so that the air inside the protective shell 5 on one side It will not easily enter the interior of the protective shell 5 on the other side. Sound insulation cotton 8 is installed inside the protective shell 5. The noise generated by the water pump when in use can be absorbed under the influence of the sound insulation cotton 8, so as to achieve the effect of silencing the water pump by the equipment. A mounting assembly 12 is installed on the surface of the protective shell 5. The mounting assembly 12 consists of a plate fixedly connected to the protective shell 5 and a bolt threadedly connected to the base 1. Under this action, the protective shell 5 can be limited so that it will not move easily, thereby avoiding the protective shell 5 from moving at will and affecting the silencing effect of the water pump. A heat dissipation mechanism 10 is installed inside the protective shell 5 on one side. Under this action, the heat dissipation mechanism 10 can dissipate heat on one side of the water pump motor, so as to avoid the water pump from overheating during use. A positioning mechanism 9 is installed inside the protective shell 5 on this side. Under this action, the positioning mechanism 9 can squeeze and fix the motor part, making it more stable when in use, avoiding the situation where the motor is not stable enough and the water pump makes loud noise, and further reducing the noise of the water pump when in use.

[0023] The positioning mechanism 9 includes a spur gear 91. There are two spur gears 91 that mesh with each other. The top of the spur gear 91 is rotatably connected to the top of the inner cavity of the protective shell 5 on one side. The bottom of the spur gear 91 is fixedly connected to a threaded sleeve 92. The inner cavity of the threaded sleeve 92 is threadedly connected to a threaded rod 93. The bottom of the threaded rod 93 is fixedly connected to a positioning plate 94. Under this action, the spur gear 91 can be rotated to make the two threaded sleeves 92 rotate at the same time, so that the threaded rod 93 can push the positioning plate 94 to move and squeeze the motor of the water pump to limit the position, so that the motor of the water pump can be more stable when working. To ensure stability, the motor in the water pump is not stable enough during operation and generates loud noise. A connecting block 11 is fixedly connected to the top of the spur gear 91. The other end of the connecting block 11 penetrates the top of the protective shell 5 and is rotatably connected to the inner wall of the penetration point. Under this function, an effective force point can be provided when the staff needs to rotate the spur gear 91, so that it is more convenient for the staff to rotate the spur gear 91. The connecting block 11 is designed as a regular hexagon, and the connecting block 11 is slidably connected to the surface of the protective shell 5. Under the effect of the shape, it is convenient for the staff to use auxiliary tools.

[0024] It is worth noting that the technical features such as the heat dissipation mechanism 10 proposed in this technical solution should be regarded as the technology in the comparative case. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected according to the conventional methods in the field, and this technical solution will not be further elaborated.

[0025] Working principle: first install the water pump on the top of the base 1, and one side of the water pump motor is close to the heat dissipation mechanism 10, and then embed the guide block 6 into the inside of the connecting groove 4. Under the action of the connecting groove 4, the guide block 6 can cooperate with the protective shell 5 to limit the position, and then use the installation component 12 to fix the protective shell 5, and then fix the protective shell 5 on the other side. After the fixation is completed, the staff uses auxiliary tools to drive the connecting block 11 to rotate, and then the connecting block 11 drives the threaded rod 93 to rotate through the cooperation of the spur gear 91 and the threaded sleeve 92, so that the positioning plate 94 can move downward, thereby squeezing and limiting the water pump motor to prevent it from moving at will during use and generating noise, thereby reducing the sound of the water pump with the cooperation of the sound insulation cotton 8. When the water pump needs to dissipate heat, turn on the heat dissipation mechanism 10 to dissipate heat to the inside of the guide block 6 of the protective shell 5 on one side.
