[0026] Figures 1 to 3 An embodiment of the online cleaning ceramic pump of the present utility model is shown. The online cleaning ceramic pump of this embodiment includes a pump body 1 and a pump rod 2. One end of the pump body 1 is provided with a cleaning liquid inlet 3, and the other end is provided with a cleaning liquid outlet 4. Between the cleaning liquid inlet 3 and the cleaning liquid outlet 4 of the pump body 1, there are arranged a filling liquid inlet 5 and a filling liquid outlet 6 which are oppositely arranged. On the side wall of one end of the pump rod 2, there is a liquid filling notch 21, and the liquid filling notch 21 is used to communicate with the filling liquid inlet 5 or the filling liquid outlet 6. On the pump rod 2, there is a first avoidance groove 22, and around the pump body 1, there is a second avoidance groove 11 for cleaning the filling surface of the pump rod 2. The first avoidance groove 22 is used to communicate the cleaning liquid inlet 3 with the second avoidance groove 11.

[0027] For this online cleaning ceramic pump, the pump rod 2 is installed in the pump body 1. In the filling state, as Figure 1As shown, the channel connecting the cleaning liquid inlet 3 to the outside is closed by a valve, preventing the cleaning liquid from entering the pump body 2. At the same time, there is no connection between the cleaning liquid inlet 3 and the second avoidance groove 11. At this time, the liquid filling notch 21 is connected to the filling liquid inlet 5, and the filling liquid enters the ceramic pump filling cavity through the liquid filling notch 21. When the filling reaches the predetermined amount, the filling stops, and the pump rod 2 is rotated to connect the liquid filling notch 21 to the filling liquid outlet 6. Under the action of the pump rod 2, the filling liquid flows out from the filling liquid outlet 6 to achieve metering filling. During the cleaning state, as Figure 2 and Figure 3 shown, no liquid enters the filling liquid inlet 5. The pump rod 2 is pulled to make the filling surface enter the first avoidance groove 11. At the same time, the cleaning liquid inlet 3 is connected to the second avoidance groove 11 through the first avoidance groove 22. The cleaning liquid enters the cleaning liquid inlet 3, and the cleaning liquid reaches the second avoidance groove 11 through the first avoidance groove 22 to clean the filling surface of the pump rod 2 and the pump body 1 (the filling surface is the area in contact with the filling liquid during the filling process, including the liquid filling notch 21). Finally, the cleaning liquid flows out from the cleaning liquid outlet 4.

[0028] For this on-line cleaning ceramic pump, by moving the position of the pump rod 2 in the pump body 1 to connect the first avoidance groove 22 on the pump rod 2 with the cleaning liquid inlet 3 and the second avoidance groove 11, the filling mode can be switched to the on-line cleaning mode. The two modes do not affect each other, and there is no need to disassemble the pump rod 2 after stopping the machine. The cleaning is convenient, saving the time for disassembling and assembling the pump rod 2, thus shortening the cleaning time and improving the cleaning efficiency.

[0029] Furthermore, as Figure 2 and Figure 3 shown, in this embodiment, the cleaning liquid inlet 3 is arranged obliquely relative to the side wall of the pump body 1. This is convenient for the entry and flow of the cleaning liquid and avoids the accumulation of the cleaning liquid. Preferably, in this embodiment, the inclination angle of the cleaning liquid inlet 3 is α, where 0 < α < 10°. By arranging the inlet 3 obliquely, it can effectively prevent the cleaning liquid from stagnating and remaining in the area of the cleaning liquid inlet 3.

[0030] Furthermore, as Figure 1 shown, in this embodiment, the pump body 1 includes a pump sleeve 12 and a housing 13. The pump sleeve 12 is sleeved outside the pump rod 2, and the housing 13 is sleeved outside the pump sleeve 12. One end of the housing 13 is connected with an end cover 14. The cleaning liquid inlet 3, the filling liquid inlet 5, and the filling liquid outlet 6 are all arranged on the pump sleeve 12 and the housing 13, and the cleaning liquid outlet 4 is arranged on the end cover 14. The housing 13 plays a protective role for the pump sleeve 12.

[0031] Furthermore, as Figure 1 and Figure 2As shown in the figure, in this embodiment, the outer shell 13 is respectively provided with a cleaning liquid input connector 31, a filling liquid input connector 51, and a filling liquid output connector 61 that are correspondingly connected to the cleaning liquid inlet 3, the filling liquid inlet 5, and the filling liquid outlet 6. The end cover 14 is provided with a cleaning liquid output connector that is correspondingly connected to the cleaning liquid outlet 4. The inlet and outlet connection connectors facilitate the connection to the corresponding liquid inlet pipes and liquid outlet pipes. Preferably, the cleaning liquid output connector is provided with a switch, and the switch is in a normally closed state and is opened when it is necessary to discharge the cleaning liquid.

[0032] Furthermore, as Figure 1 and Figure 2 shown, in this embodiment, the outer shell 13 is a metal outer shell, the end cover 14 is a metal end cover, and the outer shell 13 is threadedly connected to the end cover 14. The protection effect is good and it is convenient for threaded connection.

[0033] Furthermore, as Figure 1 and Figure 2 shown, in this embodiment, the end cover 14 is provided with a first handle 15 for screwing the end cover 14. It is convenient for disassembly and replacement.

[0034] Furthermore, as Figure 1 and Figure 2 shown, in this embodiment, the outer shell 13 is detachably connected to the pump sleeve 12. It is convenient for the disassembly and assembly of the outer shell 13 and the pump sleeve 12.

[0035] Furthermore, as Figure 1 and Figure 2 shown, in this embodiment, the pump rod 2 is provided with a second handle 23 for screwing and pushing and pulling the pump rod 2 at the extended end. It is convenient for switching the working state of the ceramic pump.

[0036] Furthermore, as Figure 2 and Figure 3 shown, in this embodiment, the length of the second avoidance groove 11 is greater than or equal to the length of the liquid filling notch 21. During cleaning, the length of the first avoidance groove 22 is greater than or equal to the distance between the cleaning liquid inlet 3 and the second avoidance groove 11 to connect the two. Ensure that the cleaning liquid can clean the filling surface smoothly and ensure the cleaning effect.

[0037] Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present utility model by using the above-disclosed technical content without departing from the scope of the technical solution of the present utility model, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model shall fall within the scope of protection of the technical solution of the present utility model.
