Description

Technical Field

[0001] This invention relates to the field of wet pulverizing pump technology, specifically a wet pulverizing pump with self-cleaning function. Background Technology

[0002] A wet pulverizer pump is a pump specifically designed to process liquids containing solid particles. Its main feature is that it can pulverize solid substances in the liquid while pumping it, thereby avoiding blockage of the pump body and pipeline system by solid particles. Wet pulverizer pumps are widely used in many industries such as sewage treatment, chemical industry, pharmaceutical industry, food processing and papermaking, and are especially suitable for scenarios that require the processing of liquids containing fibers, particles and solid impurities.

[0003] Existing wet pulverizer pumps can pulverize solidified substances in liquids, but after transporting the liquid and the pulverized material, it is inconvenient to automatically clean the inside of the wet pulverizer pump. This makes it easy for the pulverized solid particles to adhere to the filter screen and impeller, thus affecting the normal operation of the wet pulverizer pump. Furthermore, it is not convenient to perform multi-stage pulverization of solidified substances. When there is a large amount of solid material, some solid material will not be pulverized completely, and solid material will easily get stuck inside the filter screen, thus affecting the cleaning effect of the filter screen.

[0004] Combining the above issues, it becomes clear that existing wet pulverizer pumps with self-cleaning functions on the market cannot simultaneously avoid the problems mentioned above during use. Even if these problems can be solved, they require the use of external tools, thus failing to achieve the desired effect. Therefore, a wet pulverizer pump with self-cleaning function is proposed.

The outer surface of the second limiting gear 2132 meshes with the inner wall of the movable frame 2131. A limiting bearing 2129 is rotatably installed on the outer surface of the movable cylinder 2127. The outer surface of the limiting bearing 2129 is slidably connected to the inner wall of the rotating cylinder 2125. An electric telescopic rod 2128 is fixedly installed on the left side of the limiting bearing 2129. The left end of 28 is fixedly connected to the inner wall of the fixed shell 2101. The right end of the rotating rod 2104 is fixedly mounted with a first bevel gear 2105. The inner wall of the transmission cylinder 2102 is fixedly mounted with four limit frames 2106. The inner wall of each limit frame 2106 is rotatably connected with a connecting frame 2107. An impeller 2108 is fixedly mounted on one side of each connecting frame 2107. A second bevel gear 2109 is fixedly mounted on one side of each connecting frame 2107. The outer surface of each second bevel gear 2109 meshes with the outer surface of the first bevel gear 2105. The outer surface of the power output end of the bidirectional motor 2103 is fixedly mounted with a first one-way bearing 2110. A first gear 2111 is fixedly mounted on the outer surface of the first one-way bearing 2110. A rotating conveyor shaft 2112 is rotatably connected to the inner wall of the fixed housing 2101. A second one-way bearing 2134 is fixedly mounted on the outer surface of the rotating conveyor shaft 2112. A second gear 2113 is fixedly mounted on the outer surface of the second one-way bearing 2134.

An arc-shaped block 2115 is slidably connected to the inner wall of the rotating conveyor shaft 2112. A connecting block 2116 is fixedly mounted on the front of the arc-shaped block 2115. A movable disc 2117 is fixedly mounted on the front of the connecting block 2116. The outer surface of the movable disc 2117 is slidably connected to the inner wall of the fixed housing 2101.Eight cleaning brushes 2118 are fixedly installed on the inner wall of the movable disc 2117. Through the cleaning unit 21 of the cleaning mechanism 2, impurities adhering to the impeller 2108 of the wet pulverizer pump can be automatically cleaned after the liquid and pulverized materials are transported. This prevents pulverized solid materials from adhering to the impeller 2108 and affecting the normal operation of the wet pulverizer pump, while also preventing the pulverized materials from adhering to the impeller 2108 and affecting its service life.

[0024] Please see Figure 2 A handle 2119 is fixedly installed at the power output end of the stepper motor 12, and a guide block 2133 is fixedly installed at the power output end of the stepper motor 12. The position of the impeller 2108 can be viewed through the guide block 2133, and the position of the impeller 2108 can be adjusted by rotating the output shaft of the stepper motor 12 through the handle 2119.

[0025] Please see Figure 2 and Figure 4 A first connecting ring 2120 is fixedly installed on the outer surface of the fixed housing 2101, and a second connecting ring 2121 is fixedly installed on the outer surface of the stepper motor 12. The right side of the first connecting ring 2120 is in contact with the left side of the second connecting ring 2121. By setting the first connecting ring 2120 and the second connecting ring 2121, the stepper motor 12 can be easily connected to the fixed housing 2101, thereby facilitating the installation and disassembly of the stepper motor 12 and making it convenient to disassemble and maintain the stepper motor 12.

[0026] Please see Figure 4 The left side of the first connecting ring 2120 is provided with fixing bolts 2122 arranged at equal intervals. The right end of each fixing bolt 2122 passes through the first connecting ring 2120 and extends into the interior of the second connecting ring 2121. Each fixing bolt 2122 is threadedly connected to the second connecting ring 2121. By setting the fixing bolts 2122, the first connecting ring 2120 and the second connecting ring 2121 can be connected, making the connection between the first connecting ring 2120 and the second connecting ring 2121 tighter and preventing loosening between the first connecting ring 2120 and the second connecting ring 2121.

[0027] Please see Figure 2 Mounting blocks 2124 are fixedly installed on both the front and back of the base 11. Each mounting block 2124 has a connecting hole 2123 on its upper surface. By setting the mounting blocks 2124, the base 11 can be easily installed and limited, thereby preventing the wet pulverizing pump from shaking or shifting during operation and ensuring the stability of the wet pulverizing pump during operation.

[0028] The specific implementation of this embodiment is as follows: The elastic force provided by the force-bearing spring 2130 can drive the movable frame 2131 to move, so that the movable frame 2131 can limit the second limit gear 2132, thereby preventing the impeller 2108 from rotating when conveying liquid. When it is necessary to clean the impeller 2108 of the wet pulverizing pump, the position of the impeller 2108 can be checked by the pointing block 2133. Manually holding the handle 2119 can rotate the output shaft of the stepper motor 12, so that the position of the impeller 2108 can be adjusted. The telescopic property provided by the electric telescopic rod 2128 can push the limit bearing 2129 to move, so that the movable cylinder 2127 can push the movable frame. 2131 moves to one side, allowing the movable frame 2131 to release its restriction on the second limiting gear 2132. This allows the inner wall of the movable cylinder 2127 to mesh with the outer surface of the second limiting gear 2132. Power provided by the bidirectional motor 2103 drives the first limiting gear 2126 to rotate clockwise, which in turn drives the movable cylinder 2127 to rotate. This, in turn, drives the second limiting gear 2132 to rotate. The rotation of the second limiting gear 2132 drives the rotating rod 2104 to rotate, which in turn drives the first bevel gear 2105 to rotate. The rotation of the first bevel gear 2105 then drives the second bevel gear 2109 to rotate. The rotation of gear 2109 drives the connecting frame 2107 to rotate, causing the connecting frame 2107 to drive the impeller 2108 to be parallel to the transmission cylinder 2102. After the impeller 2108 is parallel to the transmission cylinder 2102, the movable cylinder 2127 is slidably reset via the electric telescopic rod 2128. At this time, the movable frame 2131, under the action of the force spring 2130, repositions the second limiting gear 2132. The output shaft of the bidirectional motor 2103 rotates counterclockwise, thereby driving the first one-way bearing 2110 to rotate. This allows the first one-way bearing 2110 to drive the first gear 2111 to rotate. The rotation of the first gear 2111 drives the first transmission belt 2114 to rotate, thus enabling the first gear 2111 to rotate. The two gears 2113 can drive the rotating conveyor shaft 2112 to rotate, so that the arc-shaped block 2115 can slide inside the rotating conveyor shaft 2112. This allows the arc-shaped block 2115 to drive the movable disc 2117 to slide back and forth inside the fixed housing 2101. As a result, the cleaning brush 2118 can brush the fine substances adhering to the surface of the impeller 2108. This allows for automatic cleaning of impurities adhering to the impeller 2108 of the wet pulverizing pump after conveying liquids and pulverized materials. This prevents the pulverized solid materials from adhering to the impeller 2108 and affecting the normal operation of the wet pulverizing pump, while also preventing the pulverized materials from adhering to the impeller 2108 and affecting its service life.

[0029] Example 2: Please refer to Figure 1 - Figure 11 The present invention provides a technical solution: a wet pulverizing pump with self-cleaning function. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The cleaning mechanism 2 also includes a reverse flushing unit 22, which is located above the base 11. The reverse flushing unit 22 is used in conjunction with the cleaning unit 21. The reverse flushing unit 22 is used to reverse flush the inside of the wet pulverizing pump.

[0030] As a further definition of the cleaning mechanism 2 of the present invention, the reverse rinsing unit 22 includes a conveyor frame 2201. The output end of the conveyor frame 2201 is fixedly connected to the inner wall of the fixed housing 2101. The outer surface of the conveyor frame 2201 is fixedly connected to the left side of the fixed housing 2101. A filter screen 2202 is fixedly installed on the inner wall of the conveyor frame 2201. The outer surface of the power output end of the bidirectional motor 2103 passes through the fixed housing 2101 and the conveyor frame 2201 in sequence and is fixedly installed with a transmission rod 2203. Six cleaning frames 2204 are fixedly installed on the outer surface of the transmission rod 2203. The left side of each cleaning frame 2204 is in contact with the right side of the filter screen 2202. An inlet pipe 2205 is fixedly connected to the left side of the conveyor frame 2201. A first solenoid valve 2206 is fixedly connected to the outer surface of the inlet pipe 2205. An outlet pipe 2206 is fixedly connected to the outer surface of the fixed housing 2101. The liquid pipe 2209 has a second solenoid valve 2210 fixedly connected to its outer surface, an inlet branch pipe 2211 fixedly connected to its outer surface, a third solenoid valve 2212 fixedly connected to its outer surface, an outlet branch pipe 2207 fixedly connected to its back side, and a fourth solenoid valve 2208 fixedly connected to its outer surface. By setting the reverse flushing unit 22, the inside of the wet pulverizing pump can be reverse-flushed, thereby preventing the filter screen 2202 in the wet pulverizing pump from adhering to the filter screen 2202 after crushing. This prevents the accumulation of a large amount of crushed solid material from clogging the filter screen 2202 and affecting the efficiency of liquid and material transportation, while also preventing the crushed solid material from affecting the service life of the filter screen 2202.

[0031] Please see Figure 3The outer surfaces of the inlet pipe 2205 and the outlet branch pipe 2207 are fixedly mounted with a first flange 2213. Each first flange 2213 has a first mounting hole 2214 on one side. The outer surfaces of the outlet pipe 2209 and the inlet branch pipe 2211 are fixedly mounted with a second flange 2215. Each second flange 2215 has a second mounting hole 2216 on one side. By setting the first flange 2213 and the second flange 2215, the inlet pipe 2205, the outlet branch pipe 2207, the outlet pipe 2209 and the inlet branch pipe 2211 can be easily connected to the external pipeline, so that while conveying liquids and pulverized solids, the inside of the wet pulverizing pump can also be reverse flushed.

[0032] The specific implementation of this embodiment is as follows: When reverse flushing of the wet pulverizing pump is required, the inlet branch pipe 2211 is connected to the external water inlet pipe through the second flange 2215, and the outlet branch pipe 2207 is connected to the external drain pipe through the first flange 2213. The first solenoid valve 2206 and the second solenoid valve 2210 are closed by the external control power supply, and the third solenoid valve 2212 and the fourth solenoid valve 2208 are opened. The impeller 2108 is driven to rotate in the reverse direction by the bidirectional motor 2103, thereby adjusting the angle of the impeller 2108. The power provided by the stepper motor 12 can drive the transmission cylinder 2102 to rotate in the reverse direction, so that the impeller 2108 can transport the liquid through the inlet branch pipe 2211 to the solid... Water in the fixed shell 2101 is transported in reverse to the conveyor frame 2201. Power provided by the bidirectional motor 2103 drives the transmission rod 2203 to rotate, which in turn drives the cleaning frame 2204 to clean the surface of the filter screen 2202. The reverse-flowing water can discharge the solid material that has been swept off through the liquid outlet branch pipe 2207, thus reverse-flushing the filter screen 2202 in the wet pulverizer pump. This prevents the crushed solid material from adhering to the filter screen 2202, preventing the accumulation of a large amount of crushed solid material that could clog the filter screen 2202 and affect the efficiency of liquid and material transportation. It also prevents the crushed solid material from affecting the service life of the filter screen 2202.

[0034] As a further definition of the crushing mechanism 3 of the present invention, the crushing mechanism 3 includes a crushing rod 301, the outer surface of which is rotatably connected to the inner wall of the conveying frame 2201. Cutting blades 302 arranged at equal intervals are fixedly mounted on the outer surfaces of both the crushing rod 301 and the transmission rod 2203. A movable rod 303 is rotatably connected to the inner wall of the conveying frame 2201. Third gears 304 are fixedly mounted on the outer surfaces of both the transmission rod 2203 and the movable rod 303. A second transmission belt 305 meshes with the outer surfaces of the two third gears 304. Fourth gears 306 are fixedly mounted on the outer surfaces of both the crushing rod 301 and the movable rod 303. A third transmission belt 307 meshes with the outer surfaces of the two fourth gears 306. A worm gear 308 is fixedly installed at one end of the movable rod 303. A worm wheel 309 meshes with the outer surface of the worm gear 308. The front of the worm wheel 309 is rotatably connected to the inner wall of the conveyor frame 2201. A power rod 310 is fixedly installed on the back of the worm wheel 309. Several crushing rods 311 are fixedly installed on the outer surface of the power rod 310. By setting up the crushing mechanism 3, it is possible to pre-crush solid substances in the liquid and also to crush solid substances in multiple stages. Thus, when crushing a large amount of solid substances, the crushing time of the solid substances can be extended, making the crushing effect of solid substances stronger and preventing solid substances from being incompletely crushed and stuck inside the filter screen 2202, affecting the cleaning effect of the filter screen 2202.

[0035] Please see Figure 10 Sealed bearings 312 are fixedly installed on the outer surfaces of the crushing rod 301, the movable rod 303, and the transmission rod 2203. The outer surface of each sealed bearing 312 is fixedly connected to the inner wall of the conveyor frame 2201. By setting the sealed bearings 312, the crushing rod 301, the movable rod 303, and the transmission rod 2203 can be supported, while preventing liquid from flowing from the gaps, thus ensuring the sealing between the crushing rod 301, the movable rod 303, and the transmission rod 2203 and the conveyor frame 2201.

[0036] The specific implementation of this embodiment is as follows: The power provided by the bidirectional motor 2103 drives the transmission rod 2203 to rotate, which in turn drives the third gear 304 to rotate, thereby driving the second transmission belt 305 to rotate. The rotation of the second transmission belt 305 drives the movable rod 303 to rotate, which in turn drives the worm gear 308 to rotate, which in turn drives the worm wheel 309 to rotate. The rotation of the worm wheel 309 drives the power rod 310 to rotate, which in turn drives the crushing rod 311 to pre-crush the solid substances in the liquid. While the movable rod 303 rotates, it drives the fourth gear 306 to rotate. The rotation of the fourth gear 306 drives the third transmission belt 307 to rotate. The rotation of the third transmission belt 307 drives the crushing rod 301 to rotate, so that the cutting blade 302 on the crushing rod 301 can perform preliminary crushing on the solid material. The cutting blade 302 on the transmission rod 2203 can further crush the solid material. Thus, while pre-crushing the solid material in the liquid, it can also perform multi-stage crushing of the solid material, preventing the solid material from being stuck inside the filter screen 2202 due to incomplete crushing and affecting the cleaning effect of the filter screen 2202.
