Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm pumps, in particular to a diaphragm pump which is easy to clean and assemble. Background Art

[0002] The diaphragm pump uses a thin film to separate the pumped liquid from the piston and the pump cylinder, thereby protecting the piston and the pump cylinder. The left side of the diaphragm that contacts the liquid is made of corrosion-resistant materials or coated with a layer of corrosion-resistant substances. The right side of the diaphragm is filled with water or oil. The diaphragm pump is a more special form of positive displacement pump. It relies on the back and forth agitation of a diaphragm to change the volume of the working chamber to suck in and discharge liquid.

[0003] The existing diaphragm pumps do not have a structure for cleaning inside. After sucking in and discharging the liquid, some liquid will adhere to the pump cavity, especially to the diaphragm. Simply flushing with water cannot clean the stains. Over time, bacteria will breed and the back-and-forth agitation effect of the diaphragm will be affected, which will have an adverse effect on the use of the diaphragm pump.

[0004] Therefore, those skilled in the art provide a diaphragm pump that is easy to clean and assemble to solve the problems raised in the above background technology. Utility Model Content

[0024] Specifically, the cleaning disc 11 is installed on the outside of the port of the left cavity 8 and the outside of the port of the right cavity 9, and its function is to clean the diaphragm 10. Clean water can be injected into the water storage chamber 13 through the water inlet pipe 12. The weight of the clean water will push the push plate 16, driving the cleaning ring 14 to rotate in the cleaning disc 11, so that the sweeping strips 15 on the inner wall of the cleaning ring 14 will rotate and rotate to clean the surface of the diaphragm 10 in contact with the sweeping strips 15. The clean water in the water storage chamber 13 can flow into the inner cavity of the cleaning disc 11 through the through holes 18 opened on each rubber sheet 17, so as to achieve the effect of washing the diaphragm 10 with water.

[0025] A connecting cavity 19 is installed on the outer side of each cleaning plate 11 away from the left cavity 8 and the right cavity 9, and connecting bolts 20 are connected through the connecting cavity 19, the cleaning plate 11 and the edge of the left cavity 8, and between the connecting cavity 19, the cleaning plate 11 and the edge of the right cavity 9. A conduit 21 is connected to the outer end of the connecting cavity 19, and a float switch 22 is arranged at the top, bottom, left and right of the conduit 21. An outlet connecting sleeve 23 is movably installed in the middle of the upper part of the conduit 21, and a pump outlet 24 is connected above the outlet connecting sleeve 23, and an inlet connecting sleeve 25 is movably connected to the middle of the lower part of the conduit 21, and a pump inlet 26 is arranged below the inlet connecting sleeve 25;

[0026] Specifically, the outlet connection sleeve 23 and the inlet connection sleeve 25 are not only connected to and communicated with the conduit 21, but can also rotate on the conduit 21, so as to adjust the direction angles of the pump outlet 24 and the pump inlet 26, making the diaphragm pump more convenient to install and use.

[0028] Specifically, the movable sleeve 27 can be rotated on the catheter 21 to adjust the position angle of the connecting plate 28 thereon. The connecting plate 28 can be used for connection, that is, the positioning screw is passed through the positioning hole 31 to fix the connecting plate 28 to the installation position, and can also be used as a bracket, that is, the rotating plate 30 is pulled apart so that the connecting plate 28 and the rotating plate 30 present a "human" structure, so that the entire diaphragm pump can be stably and well supported. The design of the structure here makes the entire diaphragm pump easy to assemble and use.

[0029] The working principle of the utility model is:

[0030] After the diaphragm pump is placed, the connecting plate 28 can be rotated to make the connecting plate 28 flat against the installation plane, and then the positioning screws can be passed through the positioning holes 31 to fix it, or the connecting plate 28 can be rotated and the rotating plate 30 can be pulled apart to make the connecting plate 28 and the rotating plate 30 present a "human" structure, so that the diaphragm pump is well and stably supported. In addition, the pump inlet 26 and the pump outlet 24 can also be adjusted in direction, and it is only necessary to rotate the inlet connecting sleeve 25 and the outlet connecting sleeve 23. The diaphragm pump starts to work and delivers compressed air to the air chamber 1 through the compressed air inlet 6. The compressed air enters the air distribution valve 4. The air distribution valve 4 introduces the compressed air into the left chamber 8 through the air channel 3, pushing the diaphragm 10 in the left chamber 8 to move, and the gas in the right chamber 9 is discharged. When the stroke end is reached, the air distribution valve 4 introduces the compressed air into the right chamber 9, pushing the diaphragm 10 to the opposite direction. The diaphragms 10 move in opposite directions, so that the two diaphragms 10 move back and forth continuously and synchronously. The diaphragm 10 in the left chamber 8 moves to the right, and the suction force causes the medium to flow in from the pump inlet 26, pushing the float switch 22. The medium flows and is transmitted along the conduit 21, and the medium in the connecting chamber 19 connected to the right chamber 9 is squeezed, pushing the float switch 22 and flowing out from the pump outlet 24. In this way, the medium is continuously sucked in from the pump inlet 26 and discharged from the pump outlet 24 in a reciprocating cycle. After the work is completed, clean water is poured into the water storage chamber 13 of the cleaning disk 11 through the water inlet pipe 12. With the help of the dead weight of the clean water, the push plate 16 is pushed, the cleaning ring 14 rotates immediately, and the sweeping bar 15 moves immediately. At the same time, the clean water in the water storage chamber 13 will reach the outside of the diaphragm 10 through the through hole 18 inside the rubber sheet 17. At this time, the rotating sweeping bar 15 can wash and clean the diaphragm 10 in a contact manner.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
