Description

Technical Field

[0001] This invention relates to the field of gas-liquid mixing pump technology, and more specifically, to a dual-motor driven gas-liquid mixing pump. Background Technology

[0002] A gas-liquid mixing pump is a device that can efficiently mix gas and liquid and generate a large number of microbubbles. It is also called a dissolved gas pump. The pump automatically draws in gas by creating negative pressure through a high-speed rotating impeller inside the pump. No external air compressor is required. The gas and liquid drawn in are strongly stirred and sheared by the turbulent flow generated by the high-speed rotation of the impeller in the pump chamber. The gas is broken into countless micron-sized microbubbles, which enter the liquid in a high-pressure dissolved state and are eventually released to form a saturated dissolved gas liquid.

[0003] According to existing technology, traditional integrated gas-liquid mixing pumps mostly use a single motor to drive two sets of conveying mechanisms. The power output is difficult to match the operating conditions of the air pump and the peristaltic pump. The two types of mechanisms have different operating speeds and loads. Long-term sharing of the same power source can easily lead to transmission misalignment, resulting in uneven conveying flow and excessive power loss. At the same time, conventional air pumps only have simple through holes at the air inlet without a dedicated filter protection structure. Dust and fibrous debris mixed in the equipment's operating environment can easily enter the pump cavity directly with the airflow. Due to long-term accumulation, they can easily jam the internal one-way valve and cause friction damage to the reciprocating diaphragm, thus affecting the gas suction efficiency. Summary of the Invention

[0004] This invention provides a dual-motor driven gas-liquid mixing pump, which uses a main motor and an auxiliary motor to drive the air pump transmission structure and the peristaltic pump transmission structure respectively. It completes gas suction and liquid extrusion transportation operations in a compact integrated layout. The umbrella-shaped structure realizes unidirectional airflow. The filter device performs preliminary impurity filtration on the intake airflow. With the addition of a detachable filter screen tube, the filter screen can be easily removed and replaced. This solves the problems mentioned in the background art, namely: long-term accumulation can easily jam the internal one-way valve and cause friction damage to the reciprocating diaphragm, thus affecting the gas suction efficiency.

[0005] To achieve the above objectives, a dual-motor driven gas-liquid mixing pump includes a main motor and a housing. The bottom of the housing and the top of the main motor are fixedly connected. An eccentric wheel is fixedly installed at the output end of the main motor. A bracket is fixedly installed inside the housing. Multiple diaphragms are fixedly installed inside the bracket. A horizontal arm slider is provided inside the bracket. A connecting shell is fixedly connected to the bottom of the housing. A pin is fixedly installed inside the connecting shell. An upper shell is fixedly connected to the top of the connecting shell. An air outlet pipe is fixedly connected to the top of the upper shell. The surface of the outer casing is provided with an air intake device, which includes two air inlets opened inside the outer casing. A connecting ring is fixedly connected to the outer casing near the two air inlets, and a filter tube is detachably connected inside the connecting ring.

[0006] In the above technical solution, an auxiliary motor is fixedly connected to one side of the outer shell, and a fixed shell is fixedly connected to the top of the auxiliary motor. Multiple sun gears are fixedly installed at the output end of the auxiliary motor. Multiple rollers are rotatably connected inside the fixed shell, and the multiple rollers mesh with the multiple sun gears respectively. A planetary carrier is provided outside the rollers and inside the fixed shell. The planetary carrier is used to drive the rollers to perform planetary motion around the sun gears. A storage shell is fixedly connected to the top of the fixed shell. A conveying pipe and a water inlet pipe are fixedly connected to one side of the storage shell. A connecting pipe is provided outside the conveying pipe and the air outlet pipe. A gas-liquid mixing pipe is provided at the bottom of the conveying pipe. The gas-liquid mixing pipe is used to discharge gas and liquid.

[0007] Secondly, a retaining ring is fixedly connected to one side of the connecting ring, and a retaining post is fixedly connected to one end of the filter tube near the retaining ring. The retaining post is detachably connected inside the retaining ring. A brush strip is detachably connected inside the filter tube. A baffle is fixedly connected to one side of the brush strip. When the brush strip slides along the axial direction of the filter tube, it drives the baffle to slide synchronously to scrape off and push away debris inside the filter tube. A pull block is fixedly connected to one end of the brush strip away from the baffle. An anti-slip post is fixedly connected to the outside of the brush strip. The outside of the anti-slip post and the inside of the filter tube are inserted into each other.

[0008] Furthermore, based on the above, a fixing device is provided on the outside of the main motor and the auxiliary motor. The fixing device includes a fixing frame fixedly connected to the outside of the main motor and the auxiliary motor. A plurality of short elastic strips are fixedly connected inside the fixing frame near the auxiliary motor. A short auxiliary strip is fixedly connected to one end of each short elastic strip near the auxiliary motor. A plurality of long elastic strips are fixedly connected inside the fixing frame near the main motor. A long auxiliary strip is fixedly connected to one end of each long elastic strip near the main motor. A main frame and a sub-frame are fixedly connected inside the fixing frame. The main frame is fitted over the plurality of long elastic strips, and the sub-frame is fitted over the plurality of short elastic strips.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: This dual-motor driven gas-liquid mixing pump uses a main motor and an auxiliary motor to drive the gas pump transmission structure and the peristaltic pump transmission structure respectively. It completes gas suction and liquid extrusion conveying operations in a compact integrated layout. A Umbrella-shaped structure ensures unidirectional gas flow. The layered shell assembly facilitates production assembly and subsequent component maintenance. A filter device performs preliminary impurity filtration on the intake airflow. A removable filter screen allows for easy filter replacement. A brush strip cleans accumulated impurities from the inner wall of the filter screen. The peristaltic pump uses a planetary transmission structure with a sun gear and rollers. The planetary carrier limits the roller's trajectory, ensuring smooth revolution around the sun gear and stable liquid delivery via pump extrusion. Liquid and gas converge at the gas-liquid mixing point through corresponding pipelines for mixing and output. A fixing device absorbs vibration energy generated by the motor operation. The frame structure also limits the position of the elastic components, preventing displacement of the buffer components over time and effectively reducing the transmission of vibration during operation.

[0012] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0013] Long-term accumulation can easily cause jamming of internal one-way valves and friction damage to the reciprocating diaphragm, thus affecting gas suction efficiency.

[0014] Therefore, in view of the above-mentioned problems, the present invention provides a dual-motor driven gas-liquid mixing pump, with reference to... Figure 1 and Figure 2 As shown, it includes a main motor 1 and a housing 2. The bottom of the housing 2 and the top of the main motor 1 are fixedly connected. An eccentric wheel 3 is fixedly installed at the output end of the main motor 1. The eccentric wheel 3 is driven by the motor to rotate, and can output reciprocating driving force to provide power for the air pump's suction action. A bracket 4 is fixedly installed inside the housing 2. Multiple diaphragms 5 are fixedly installed inside the bracket 4. The bracket 4 is used to fix the multiple sets of diaphragms 5 to ensure that the diaphragms 5 are installed in a regular position and to avoid displacement or misalignment during operation. The bracket 4 has a horizontal arm slider inside, which transmits the power generated by the eccentric wheel 3 to drive the diaphragm 5 to complete a regular deformation action, thereby changing the internal volume of the pump chamber and realizing gas suction and compression operations. The bottom of the outer shell 2 is fixedly connected to the connecting shell 6, and the connecting shell 6 is fixedly installed with the umbrella pin 7. The umbrella pin 7 is placed inside the connecting shell 6 to realize unidirectional air flow and prevent gas backflow. The top of the connecting shell 6 is fixedly connected to the upper shell 8, and the top of the upper shell 8 is fixedly connected to the air outlet pipe 9. The upper shell 8 and the air outlet pipe 9 form an air outlet channel, and the gas pressurized by the pump body can be transported outward in an orderly manner along the pipeline.

[0015] refer to Figure 2As shown, an auxiliary motor 10 is fixedly connected to one side of the outer casing 2. The auxiliary motor 10 independently provides power to the peristaltic pump. A fixed housing 11 is fixedly connected to the top of the auxiliary motor 10. Multiple sun teeth 12 are fixedly installed at the output end of the auxiliary motor 10. The multiple sun teeth 12 rotate synchronously to realize the distributed transmission of power and improve the uniformity of power output. Multiple rollers 14 are rotatably connected inside the fixed housing 11. The multiple rollers 14 mesh with the multiple sun teeth 12 respectively, converting the rotational power of the auxiliary motor 10 into the revolution and rotational power of the rollers 14, ensuring the continuity of liquid delivery. A planetary carrier is provided on the outside of the roller 14 and inside the fixed shell 11. The planetary carrier is used to drive the roller 14 to perform planetary motion around the sun tooth 12. A storage shell 13 is fixedly connected to the top of the fixed shell 11. A delivery pipe 15 and a water inlet pipe 16 are fixedly connected to one side of the storage shell 13, which can divide the liquid input and output channels and realize the orderly delivery of liquid. A connecting pipe is provided on the outside of the delivery pipe 15 and the air outlet pipe 9. A gas-liquid mixing pipe is provided at the bottom of the delivery pipe 15. The gas-liquid mixing pipe is used to discharge gas and liquid, so that the gas delivered by the air pump and the liquid delivered by the peristaltic pump can be fully combined here and discharged together.

[0016] refer to Figure 3 and Figure 4 As shown, the surface of the outer casing 2 is provided with an air intake device 17. The air intake device 17 includes two air inlets 171 opened inside the outer casing 2. The air inlets 171 ensure uniform airflow distribution. A connecting ring 172 is fixedly connected to the outer casing 2 near the two air inlets 171. The filter tube 173 can be fixedly installed by the connecting ring 172. The filter tube 173 is detachably connected inside the connecting ring 172. A retaining ring 174 is fixedly connected to one side of the connecting ring 172. A retaining post 175 is fixedly connected to one end of the filter tube 173 near the retaining ring 174. The retaining post 175 is detachably connected to the inside of the retaining ring 174. The retaining ring 174 and the retaining post 175 form a snap-fit ​​structure to enable quick installation and removal of the filter tube 173. At the same time, the filter tube 173 filters and intercepts the air entering the pump body, preventing dust and fine debris in the air from entering the cavity and reducing the wear and jamming of precision moving parts such as the diaphragm 5 and the umbrella pin 7 caused by impurities.

[0017] refer to Figure 4 - Figure 6 As shown, a brush strip 176 is detachably connected inside the filter tube 173. A baffle 177 is fixedly connected to one side of the brush strip 176. The brush strip 176 slides along the axial direction of the filter tube 173, which simultaneously drives the baffle 177 to move. The brush scrapes off the dust and debris attached to the tube wall, and the baffle 177 pushes the cleaned debris outward and discharges it. A pull block 178 is fixedly connected to the end of the brush strip 176 away from the baffle 177. The pull block 178 makes it easy for the operator to hold and apply force to complete the push and pull cleaning action. An anti-slip post 179 is fixedly connected to the outside of the brush strip 176. The anti-slip post 179 is inserted and cooperates with the inside of the filter tube 173. The anti-slip post 179 increases the friction between the brush strip 176 and the filter tube 173, thereby reducing the possibility of the brush strip 176 coming off when cleaning is not being performed.

[0018] refer to Figure 7 and Figure 8 As shown, a fixing device 18 is provided on the outside of the main motor 1 and the auxiliary motor 10. The fixing device 18 includes a fixing frame 181 fixedly connected to the outside of the main motor 1 and the auxiliary motor 10. A plurality of short elastic strips 182 are fixedly connected inside the fixing frame 181 near the auxiliary motor 10. A short auxiliary strip 183 is fixedly connected to one end of the short elastic strip 182 near the auxiliary motor 10. The short elastic strips 182 and the short auxiliary strips 183 can adapt to the high-frequency vibration generated by the operation of the auxiliary motor 10, and absorb the vibration energy by relying on elastic deformation to weaken the vibration transmission effect. Multiple long elastic strips 184 are fixedly connected inside the fixed frame 181 near the main motor 1. A long auxiliary strip 185 is fixedly connected to one end of the long elastic strip 184 near the main motor 1. The long elastic strips 184 and the long auxiliary strip 185 are adapted to the low-frequency pulsating vibration generated during the operation of the main motor 1. Elastic buffer components are configured according to the different vibration characteristics of the two types of motors. A main frame 186 and a sub-frame 187 are fixedly connected inside the fixed frame 181. The main frame 186 is fitted outside the multiple long elastic strips 184, and the sub-frame 187 is fitted outside the multiple short elastic strips 182. The main frame 186 forms an external limiting constraint on the long elastic strips 184, and the sub-frame 187 forms an external limiting constraint on the short elastic strips 182, which limits the elastic strips from misalignment or excessive deformation.

[0019] Working principle of the invention: During operation, the main motor 1 is powered on and drives the output end eccentric wheel 3 to rotate. During the rotation of the eccentric wheel 3, it continuously drives the horizontal arm slider to reciprocate, thereby pulling the diaphragms 5 on the inner side of the bracket 4 to complete the reciprocating deformation, so that the internal volume of the pump chamber changes alternately. Air is filtered through the filter tube 173 and then enters the pump chamber through the air inlet 171. After the filter tube 173 removes dust and fine impurities from the air, it flows into the pump chamber. The one-way air passage structure formed by the umbrella pin 7 avoids the backflow of gas and completes the continuous suction and pressurization of gas. The pressurized gas passes through the connecting shell 6 and the upper shell 8 in sequence and is finally discharged outward from the air outlet pipe 9.

[0020] At the same time, the auxiliary motor 10 on one side of the outer shell 2 operates synchronously. The auxiliary motor 10 drives the output sun gear 12 to rotate synchronously. Under the limiting and guiding action of the planetary carrier, multiple rollers 14 meshing with the sun gear 12 perform planetary motion, forming uniform compression on the pipeline. External water is introduced into the equipment through the water inlet pipe 16 and is stably transported along the conveying pipe 15 under the compression action of the rollers 14, completing the continuous liquid conveying operation.

[0021] After the gas and liquid are transported through independent pipelines, they are gathered together inside the gas-liquid mixing pipe to complete the fusion, and then discharged outwards in a gas-liquid mixed state.

[0022] When the equipment is working, the operator periodically holds the pull block 178 to drive the brush strip 176 to slide along the axial direction of the filter tube 173. With the help of the brush strip 176 and the baffle 177, the impurities and debris accumulated on the inner wall of the filter tube 173 are cleaned and discharged. The vibration generated by the operation of the main motor 1 and the auxiliary motor 10 is buffered and dissipated by the long elastic strip 184 assembly and the short elastic strip 182 assembly, respectively. With the limiting effect of the main frame 186 and the auxiliary frame 187 on the elastic components, the buffer structure is stable and effective, effectively suppressing the overall vibration amplitude of the equipment.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
