Description

Technical Field

[0001] The utility model relates to the technical field of wind bag pumps, in particular to a continuous liquid supply type wind bag pump. Background Art

[0002] A bellows pump is a device that uses air pressure or hydraulic principles to create fluid movement. It usually consists of a flexible, expandable bladder or pump head that expands when subjected to external gas or liquid pressure, and then contracts when the pressure is released. This movement causes fluid to be drawn in and out, thereby achieving liquid delivery. The working principle of a bellows pump is similar to that of the human heart. When the bladder expands, the surrounding fluid is drawn into the pump; when the bladder contracts, the fluid is expelled. This operation can be performed continuously, thereby achieving continuous liquid delivery.

[0003] The existing bellows pump for continuous liquid supply has a disc-shaped pump body directly connected to the pipeline and has intermittent water suction mechanisms sealed at both ends. When working, the intermittent water suction mechanism alternately sucks and drains water, so that the bellows pump can continuously transport corrosive liquid to the pipeline, thereby improving the working efficiency of the pump. It is well known that pumps are generally driven by motors, but the existing bellows pumps need to cooperate with reciprocating suction and exhaust mechanisms to achieve this, which increases the complexity of the bellows pump when setting it up, requires more parts and mechanical structures, and increases the installation cost and maintenance difficulty. In view of this, the utility model proposes a continuous liquid supply bellows pump. Utility Model Content

The left and right cavities are respectively connected to two groups of liquid storage cylinders. The liquid inlet pipe is installed at one end of the infusion tube, and the liquid outlet pipe is installed at the end of the infusion tube away from the liquid inlet pipe. The liquid inlet pipe and the liquid outlet pipe are both Y-shaped. The liquid inlet pipe and the liquid outlet pipe are simultaneously connected to the left and right cavities of the infusion tube. Two groups of check valves are respectively installed in the liquid inlet pipe and the liquid outlet pipe.

[0008] Optionally, the driving mechanism includes connecting rods, moving rods, fixed rods, and a moving ring. Multiple groups of connecting rods are fixedly connected to the sides of the two groups of wind bags away from each other.

[0012] Compared with the prior art, the utility model has the following beneficial technical effects:

[0013] The utility model can drive the rotating plate to rotate through the setting of the driving mechanism through the motor, and drive the moving ring to reciprocate at the same time, so that when one group of wind bags is in a compressed state, the other group of wind bags is in an expanded state, and the states of the two groups of wind bags are alternated with each other, thereby realizing the reciprocating motion of multiple groups of pistons and driving the flow of liquid medium;

[0030] Example

[0031] like Figure 1-3 As shown, the utility model proposes a continuous liquid supply type wind bag pump, including a pump body 1, the pump body 1 includes an outer shell 11, an infusion tube 12, a liquid storage cylinder 13, a piston 14, and a wind bag 15. The infusion tube 12 is arranged in the outer shell 11, and four groups of liquid storage cylinders 13 are distributed in an annular array on the outer circle of the infusion tube 12 and are connected with the infusion tube 12. One end of the liquid storage cylinder 13 is fixedly connected to the inner wall of the outer shell 11, and the piston 14 is slidably connected to the liquid storage cylinder 13, so that the liquid in the infusion tube 12 can be sucked into the liquid storage cylinder 13 when the piston 14 slides in the liquid storage cylinder 13. Two groups of wind bags 15 are symmetrically arranged on the left and right sides of the outer shell 11, and the two groups of wind bags 15 are respectively connected with the two groups of liquid storage cylinders 13, so as to drive the piston 14 to slide in the liquid storage cylinder 13 when the wind bag 15 is compressed or expanded. The pump body 1 also includes multiple groups of limiting rings 16, and the inner wall of each group of liquid storage cylinders 13 is fixedly connected with two groups of limiting rings 16. The piston 14 slides between the two groups of limiting rings 16 in the liquid storage cylinder 13, and the limiting rings 16 are used to limit the position of the piston 14. The pump body 1 also includes a partition 17, a liquid inlet pipe 18, and a liquid outlet pipe 19. The partition 17 is fixedly connected to the infusion tube 12 and divides the infusion tube 12 into two left and right cavities. The left and right cavities are respectively connected to the two groups of liquid storage cylinders 13. When the left wind bag 15 is compressed and expanded, it drives the liquid in the left cavity to move through the two groups of pistons 14 on the left, and the same is true for the right side. The liquid inlet pipe 18 is installed at one end of the infusion tube 12, and the liquid outlet pipe 19 is installed at the end of the infusion tube 12 away from the liquid inlet pipe 18. The liquid inlet pipe 18 and the liquid outlet pipe 19 are both arranged in a Y shape. The liquid inlet pipe 18 and the liquid outlet pipe 19 are both connected to the left and right cavities of the infusion tube 12 at the same time. Two sets of check valves are respectively installed in the liquid inlet pipe 18 and the liquid outlet pipe 19 to limit the flow direction of the liquid in the order of the liquid inlet pipe 18 to the infusion tube 12 and then to the liquid outlet pipe 19.

[0032] Furthermore, the bellows pump comprises two sets of support frames 2 symmetrically arranged on both sides of the outer shell 11 for supporting the pump body 1. Both sets of support frames 2 are fixedly connected to the infusion tube 12, so that the position of the pump body 1 is stable.

[0033] For details, please refer to Figure 1 , Figure 2 and Figure 4 The above-mentioned air bag pump also includes a driving mechanism 3 for driving the pump body 1 to work. The driving mechanism 3 includes a connecting rod 31, a moving rod 32, a fixed rod 33, and a moving ring 34. The two groups of air bags 15 are fixedly connected to the sides away from each other with multiple groups of connecting rods 31. The moving rod 32 is fixedly connected to the end of the multiple groups of connecting rods 31 away from the air bag 15. When the moving rod 32 moves, it pulls the air bag 15 through the connecting rod 31, thereby realizing the transformation of the air bag 15 between the compressed state and the expanded state. The two groups of fixed rods 33 are fixedly connected to the opposite sides of the two groups of moving rods 32, and the moving ring 34 is fixedly connected between the two groups of fixed rods 33. When the moving ring 34 moves, it drives the moving rod 32 to move synchronously through the fixed rod 33. The driving mechanism 3 also includes a slider 35 and a rotating plate 36. The slider 35 is slidably connected to the moving ring 34. One end of the slider 35 is fixedly connected to the rotating plate 36. A mounting plate 4 is also installed between the two groups of support frames 2. The mounting plate 4 is used to install a motor whose output end is fixedly connected to the rotating plate 36. After the motor is installed, the motor drives the rotating plate 36 to rotate when it is started, so that the rotating plate 36 drives the slider 35 to move. At the same time, the slider 35 slides in the moving ring 34, so that the moving ring 34 reciprocates. The driving mechanism 3 also includes a limiting sleeve 37 and a fixed plate 38. The two groups of limiting sleeves 37 are slidably connected to the two groups of fixed rods 33 respectively. A fixed plate 38 is fixedly connected between each group of limiting sleeves 37 and the two groups of support frames 2, which is used to limit when the fixed rod 33 moves, so that the reciprocating motion of the moving ring 34 is smooth.

[0034] In this embodiment, after the motor is mounted on the mounting plate 4, the output end of the motor is fixedly connected to the rotating plate 36. At this time, when the motor is started, the slider 35 is driven to rotate through the rotating plate 36, and the slider 35 slides in the moving ring 34. The moving ring 34 moves under the limiting action of the fixed rod 33, so that the moving ring 34 performs reciprocating motion. At this time, the moving rod 32 is driven to move synchronously through the fixed rod 33, and the moving rod 32 reciprocates and drives the wind bag 15 to compress or expand. When the moving ring 34 moves to the left, the space in the wind bag 15 on the left becomes larger and the pressure becomes lower, thereby driving the two groups of pistons 14 on the left to slide in the liquid storage cylinder 13 away from the infusion tube 12, and the liquid in the left cavity of the infusion tube 12 is sucked into the two groups of liquid storage cylinders 13 on the left, and due to the setting of the check valve in the liquid outlet pipe 19, the liquid only enters the infusion tube 12 through the liquid inlet pipe 18. When the moving ring 34 moves to the right, the space in the left wind bag 15 decreases and the pressure increases, thereby driving the two groups of pistons 14 on the left to move in the direction of the liquid storage cylinder 13 close to the infusion tube 12, thereby pushing the liquid in the two groups of liquid storage cylinders 13 on the left into the left chamber of the infusion tube 12. Due to the setting of the check valve, the liquid in the infusion tube 12 cannot be discharged through the liquid inlet pipe 18 after the pressure increases, and can only be discharged through the liquid outlet pipe 19, thereby realizing the delivery of the liquid. When the moving ring 34 reciprocates, the right wind bag 15 similarly delivers the liquid through the right chamber, and the left and right wind bags 15 work alternately to achieve continuous liquid supply.

[0035] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
