Description

Technical Field

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

[0002] A pneumatic diaphragm pump is a device that uses air pressure to drive a diaphragm to pump liquids or various granular materials. Pneumatic diaphragm pumps are easy to use, simple in structure, and have a long service life. They are widely used in chemical, printing and dyeing, coating, pharmaceutical, and other fields. Pneumatic diaphragm pumps can be used to transport and pump materials that are high in temperature, volatile, and highly viscous, and are not suitable for other types of pumps.

[0003] However, due to the large differences in the types of transported liquids or various particulate materials, the liquids or various particulate materials can easily adhere to the diaphragm and cause contamination. If the pneumatic diaphragm pump is completely disassembled to remove the diaphragm for cleaning, it will be time-consuming and labor-intensive. Therefore, there is an urgent need for an easy-to-clean pneumatic diaphragm pump that can effectively clean the diaphragm without disassembling the pneumatic diaphragm pump. Utility Model Content

[0007] The cleaning pipe mechanism comprises a liquid inlet cleaning pipe and a liquid outlet cleaning pipe, wherein both ends of the liquid inlet cleaning pipe are respectively connected to the pipeline main body mechanism and the side wall of the diaphragm cavity, and both ends of the liquid outlet cleaning pipe are respectively connected to the pipeline main body mechanism and the side wall of the diaphragm cavity.

[0015] Compared with the prior art, the advantages and positive effects of the utility model are:

[0016] (1) The magnetic cleaning mechanism includes a magnetic cleaning pad, a magnetic component 1 and a magnetic component 2. When the pneumatic diaphragm pump is working, the magnetic cleaning pad is fixed to the lower end of the inner side surface of the side wall of the diaphragm cavity by the gravity of the magnetic cleaning pad itself and the magnetic attraction of the magnetic component 1. At this time, the magnetic cleaning pad does not affect the operation of the pneumatic diaphragm pump. When the diaphragm of the pneumatic diaphragm pump needs to be cleaned, the piston rod of the cylinder mechanism is adjusted to the shortest. At this time, the diaphragm fits the top plate of the diaphragm cavity. The magnetic cleaning pad moves correspondingly through the movement of the magnetic component 2 on the top plate of the diaphragm cavity, thereby realizing the cleaning work without disassembling the pneumatic diaphragm pump, and the cleaning effect is good for larger impurities.

[0017] (2) The cleaning pipe mechanism includes a liquid inlet cleaning pipe and a liquid outlet cleaning pipe. Close valves 1, 2 and 3, open the liquid inlet valve and the liquid outlet valve, adjust the piston rod of the cylinder mechanism to the longest position, and the cleaning liquid enters the diaphragm cavity of the pneumatic pump from the liquid inlet cleaning pipe and then flows out from the liquid outlet cleaning pipe. The cleaning liquid collides with the diaphragm in the diaphragm cavity of the pneumatic pump to clean the diaphragm. Due to the small space, the cleaning effect is better for impurities with smaller particles;

[0018] (3) The pore sizes of the filter holes of the first filter, the filter holes of the second filter, and the filter holes of the third filter are reduced in sequence, so as to achieve layered filtration for impurity particles with different inner diameters, thereby preventing a single filter from generating a large resistance to the connecting pipe, thereby clogging the connecting pipe;

[0019] (4) The elastic cleaning pad is installed on the outer side of the magnetic part to play a buffering role, avoid scratching the diaphragm, and protect the magnetic part;

[0020] (5) The end of the magnetic part close to the side wall of the diaphragm cavity is an arc-shaped surface, which is adapted to the arc-shaped part of the side wall of the diaphragm cavity, thereby increasing the contact area and ensuring a good magnetic attraction effect on the magnetic cleaning pad.

[0049] Working principle of the easy-to-clean pneumatic diaphragm pump:

[0050] When it is necessary to clean the pneumatic diaphragm pump that is easy to clean, first adjust the piston rod of the cylinder mechanism 5 to the shortest, at which time the diaphragm 3 fits with the diaphragm cavity top plate 82, and the magnetic cleaning pad 21 moves correspondingly on the lower end surface of the diaphragm 3 through the movement of the magnetic member 23 on the upper end of the diaphragm cavity top plate 82, so as to clean the large particles of impurities.
