Abstract
Description
Technical Field
[0001] This utility model belongs to the field of centrifugal water pumps for chemical industry, specifically a centrifugal water pump for chemical production. Background Technology
[0002] Centrifugal water pumps are power pumps that increase fluid velocity through impeller rotation. They are a commonly used fluid transport device with advantages such as simple structure, large flow rate, uniform flow rate, and convenient operation. They are suitable for transporting special liquids containing corrosive substances, suspended solids, etc. Centrifugal water pumps are often used in chemical production to transport liquid chemical raw materials.
[0003] According to Chinese Patent Application No. 202222963647.7, a multifunctional centrifugal water pump device is disclosed, including a base. A horizontal plate is slidably installed on the top of the base, and the centrifugal water pump body is fixedly installed on the top of the horizontal plate. The base is internally equipped with a shock-absorbing mechanism and a buffer mechanism for buffering and shock absorption. The shock-absorbing mechanism includes a groove, a slider, a connecting rod, a telescopic spring, and a shock absorber. The inner bottom wall of the base has two grooves. Through the shock-absorbing mechanism, when the device is running, the horizontal plate will drive the connecting rods on both sides to squeeze the sliders on both sides. The sliders move in opposite directions to compress the telescopic spring. The extension and contraction of the telescopic spring and the shock absorber can play a good buffering and shock absorption role, avoiding rigid impact between the equipment and the ground, realizing buffering and shock absorption during the operation of the device, and helping to improve the service life of the device.
[0004] The comparative case effectively solves the problems of easy clogging and vibration damage in existing centrifugal water pumps during operation, and has the advantages of reducing vibration and clogging, effectively improving the service life of centrifugal water pumps. However, this type of centrifugal water pump filters liquid through a filter screen, which makes the filter screen surface easy to accumulate debris. Although the designed cleaning structure can clean the filter screen, it is necessary to clean the debris filtered in the collection box frequently. This requires stopping the centrifugal water pump during cleaning, which leads to frequent shutdowns of the centrifugal water pump during production, thereby reducing the pumping efficiency and production efficiency of the centrifugal water pump.

Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.
[0023] Example 1
[0024] like Figure 1-4 As shown, this is the first embodiment of the present invention. This embodiment provides a centrifugal water pump for chemical production, including a support base 1. The support base 1 includes a support assembly 11 and a vibration damping assembly 12. A centrifugal water pump 2 is installed on the top of the support assembly 11. The centrifugal water pump 2 is used to transport fluid. The support assembly 11 is used to provide support for the centrifugal water pump 2. The vibration damping assembly 12 is used to buffer the vibration of the centrifugal water pump 2. A filter assembly 3 is provided on one side of the centrifugal water pump 2. The filter assembly 3 is used to filter the fluid.
[0025] like Figure 1-4 As shown, the support component 11 provides installation space for the centrifugal water pump 2, and the vibration damping component 12 can buffer the vibration generated during the operation of the centrifugal water pump 2, thereby enabling the centrifugal water pump 2 to operate stably and reducing the occurrence of damage to the centrifugal water pump 2 due to vibration. When the centrifugal water pump 2 is conveying fluid chemical raw materials, the filter component 3 can filter and crush larger solid particles in the raw materials, thereby preventing the centrifugal water pump 2 from clogging during conveying, and thus effectively improving the conveying efficiency of the centrifugal water pump 2.
[0026] Example 2
[0027] Reference Figure 1 and 3 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0028] In this embodiment, the centrifugal water pump 2 includes a motor 201, a protective cover 202, a housing 203, an impeller 204, a coupling 205, a transmission rod 206, a connecting pipe 207, a drain pipe 208, and an exhaust assembly 209. The motor 201, the protective cover 202, and the housing 203 are all mounted on the top of the support plate 111, and the impeller 204 is mounted in the inner cavity of the housing 203.
[0029] The transmission rod 206 is installed in the inner cavity of the protective cover 202. The output shaft of the motor 201 is connected to the coupling 205. The transmission rod 206 is fixedly connected to one side of the coupling 205. The end of the transmission rod 206 away from the coupling 205 passes through the inner cavity of the outer shell 203 and is fixedly connected to the impeller 204. The connecting pipe 207 is connected to the water inlet end of the outer shell 203. The drain pipe 208 is connected to the water outlet end of the outer shell 203. The exhaust assembly 209 is installed on the surface of the drain pipe 208.
[0030] like Figure 1 and 3 As shown, the protective cover 202 provides protection for the coupling 205, preventing it from entangling surrounding objects during high-speed rotation. The motor 201, protective cover 202, and housing 203 are all bolted to the top of the support plate 111, allowing for easy disassembly and maintenance. The output shaft of the motor 201 rotates, causing the coupling 205 to rotate. This, in turn, drives the impeller 204 to rotate at high speed within the housing 203 via the transmission rod 206. The coupling 205 provides buffering and shock absorption, thereby reducing the impact of centrifugal force. The vibration of the water pump 2 during rotation, and the centrifugal force generated by the high-speed rotation of the impeller 204, can draw external fluid through the filter assembly 3 and the connecting pipe 207 into the inner cavity of the outer casing 203, and deliver it to the designated location through the drain pipe 208. The exhaust assembly 209 consists of an exhaust pipe and a valve. The exhaust assembly 209 can discharge the air in the inner cavity of the outer casing 203, thereby preventing the reduction of the conveying efficiency of the centrifugal water pump 2 due to the entry of air into the inner cavity of the outer casing 203. The connection between the transmission rod 206 and the outer casing 203 can be sealed by a mechanical seal.
[0031] Example 3
[0032] Reference Figure 1-4 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0033] In this embodiment, the support assembly 11 includes a support plate 111 and a base 112. The support plate 111 is located on top of the base 112. The vibration damping assembly 12 includes a damper 121, a first mounting plate 122, a second mounting plate 123, a support spring 124, and a bolt body 125. The first mounting plate 122 is fixed to the periphery of the surface of the support plate 111, and the second mounting plate 123 is fixed to the periphery of the surface of the base 112.
[0034] The damper 121 is installed in the inner cavity of the base 112. The two ends of the damper 121 are fixedly connected to the support plate 111 and the base 112 respectively. The two ends of the support spring 124 are fixedly connected to the first mounting plate 122 and the second mounting plate 123 respectively. One end of the bolt body 125 passes through the first mounting plate 122 and is threadedly connected to the second mounting plate 123.
[0035] The filter assembly 3 includes a filter assembly 3, a first housing 301, a second housing 302, a filter screen 303, a crusher 304, a connecting rod 305, and an inlet pipe 306. The first housing 301 and the second housing 302 are connected by bolts and threads. The filter screen 303 and the crusher 304 are both installed in the inner cavity of the first housing 301.
[0036] The filter screen 303 is fixedly connected to the inner wall of the first housing 301. The crusher 304 is located on one side of the filter screen 303. One end of the connecting rod 305 is fixedly connected to the crusher 304. The other end of the connecting rod 305 passes through the inner cavity of the housing 203 and is fixedly connected to the impeller 204. One end of the liquid inlet pipe 306 is connected to the second housing 302.
[0037] like Figure 1-4 As shown, the vibration generated during the operation of the centrifugal water pump 2 is absorbed and buffered by the damper 121 and the support spring 124, thereby reducing the vibration of the centrifugal water pump 2. The bolt body 125 passes through the first mounting plate 122 and is threadedly connected to the second mounting plate 123, which can connect the support plate 111 to the base 112. The fluid first enters the inner cavity of the first housing 301 through the inlet pipe 306. The filter screen 303 can intercept larger particles in the fluid. When the impeller 204 rotates, it drives the crusher through the connecting rod 305. The crusher 304 rotates at high speed inside the first housing 301, enabling it to crush larger solid particles so that they can be drawn into the centrifugal water pump 2, reducing the likelihood of impeller 204 clogging. The second housing 302 is bolted to the filter screen 303, allowing for easy disassembly for maintenance of the crusher 304 and the filter screen 303. The second housing 302 and the first housing 301 are sealed with a sealing ring to prevent fluid from leaking out from the connection between them.
[0038] In operation, the output shaft of motor 201 rotates, driving coupling 205 to rotate. Coupling 205, via transmission rod 206, drives impeller 204 to rotate at high speed within the inner cavity of housing 203. The centrifugal force generated by the high-speed rotation of impeller 204 draws external fluid through inlet pipe 306 into the inner cavity of first housing 301. As impeller 204 rotates, it drives crusher 304 to rotate at high speed within the inner cavity of first housing 301 via connecting rod 305. This allows crusher 304 to break larger solid particles, enabling them to be drawn into centrifugal water pump 2, reducing the risk of impeller 204 clogging. The crushed solid particles, along with the fluid, enter housing 203. The water pump 2 is pumped into the inner cavity of the outer shell 203 and transported to a designated location through the drain pipe 208. The air in the inner cavity of the outer shell 203 can be discharged through the exhaust assembly 209, thereby preventing the reduction of the pumping efficiency of the centrifugal water pump 2 due to air entering the inner cavity of the outer shell 203. The vibration generated by the centrifugal water pump 2 during operation is absorbed and buffered by the damper 121 and the support spring 124, thereby reducing the vibration of the centrifugal water pump 2. This enables the centrifugal water pump 2 to carry out pumping operations, thereby preventing the centrifugal water pump 2 from becoming blocked and affecting the pumping efficiency of the centrifugal water pump 2, and effectively improving the pumping efficiency of the centrifugal water pump 2.
