Description

Technical Field

[0001] The utility model relates to the technical field of peristaltic pumps, in particular to a planetary tubeless peristaltic pump. Background Art

[0002] Peristaltic pumps consist of three parts: drive, pump head and hose. The main competitive advantages of peristaltic pumps are that the fluid is isolated in the pump tube, the pump tube can be quickly replaced, the fluid is reversible, dry operation is possible, and maintenance costs are low.

[0003] Existing peristaltic pumps usually use extrusion hoses to transport liquids. However, thinner hoses are usually used, and the flow rate of the liquid is limited to a certain extent, thus affecting the liquid transportation effect. For this reason, we propose a planetary tubeless peristaltic pump. Utility Model Content

[0004] In view of the above problems, the utility model provides a planetary tubeless peristaltic pump, which has the advantage of conveying liquid with a large flow rate.

[0005] The technical solution of the utility model is:

[0006] A planetary tubeless peristaltic pump comprises a motor, a mounting plate is installed on one side of the motor, an outer cavity shell is installed on one side of the mounting plate, an outer gear ring integrated bracket is installed inside the outer cavity shell, a driving tooth is fixedly connected to the output shaft of the motor, three transmission teeth are meshed and connected on the outer side of the driving tooth, a bracket is installed on one side of the transmission tooth, a first bearing is installed on one side of the bracket, a second bearing is also installed in the middle of the outer gear ring integrated bracket, three pins are installed on the outer side of the outer gear ring integrated bracket, rollers are movably connected to the surface of the pins, a rubber soft sleeve is installed on the outer side of the outer gear ring integrated bracket and is located inside the outer cavity shell, and an upper cover plate is also installed on one side of the outer cavity shell.

[0007] In a further technical solution, three mounting blocks are installed on the outside of the outer cavity shell, and fixing screws are passed through the inside of the mounting blocks. One end of the fixing screw is installed on the upper cover plate, and the other end of the fixing screw is installed on the mounting plate.

[0008] In a further technical solution, a water inlet is installed on one side of the top end of the outer cavity shell, and a water outlet is installed on the other side of the top end of the outer cavity shell.

[0009] In a further technical solution, a tooth block is provided on the inner wall of one end of the outer gear ring integrated bracket, and the tooth block is meshingly connected with the transmission tooth.

[0010] In a further technical solution, a blocking piece is installed at the top end of the rubber soft sleeve, and the blocking piece and the rubber soft sleeve are both made of rubber material.

[0011] The beneficial effects of the utility model are:

[0012] The three rollers are driven by a motor to rotate, and the rollers squeeze the rubber sleeve so that the liquid between the rubber sleeve and the outer cavity shell is squeezed and flows out from the water outlet. This method can increase the flow rate of the liquid and eliminate the setting of the hose, making maintenance more convenient. The three rollers squeeze the liquid to make the pulsation more uniform, and the planetary drive method is used to make the rollers rotate more smoothly, thereby extending the life of the device.

[0016] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0017] Example:

[0018] like Figure 1 As shown, the planetary tubeless peristaltic pump includes a motor 1, a mounting plate 2 is installed on one side of the motor 1, an outer cavity shell 12 is installed on one side of the mounting plate 2, an outer gear ring integrated bracket 7 is installed inside the outer cavity shell 12, a driving tooth 4 is fixedly connected to the output shaft of the motor 1, three transmission teeth 3 are meshed and connected on the outer side of the driving tooth 4, a bracket 5 is installed on one side of the transmission tooth 3, a first bearing 6 is installed on one side of the bracket 5, a second bearing 10 is also installed in the middle of the outer gear ring integrated bracket 7, three pins 9 are installed on the outer side of the outer gear ring integrated bracket 7, a roller 8 is movably connected to the surface of the pins 9, and a The rubber soft sleeve 11 is located inside the outer cavity shell 12, and an upper cover plate 13 is also installed on one side of the outer cavity shell 12. Three mounting blocks are installed on the outside of the outer cavity shell 12, and a fixing screw 14 is passed through the inside of the mounting block. One end of the fixing screw 14 is installed on the upper cover plate 13, and the other end of the fixing screw 14 is installed on the mounting plate 2. A water inlet is installed on one side of the top of the outer cavity shell 12, and a water outlet is installed on the other side of the top of the outer cavity shell 12.
