[0027] In this utility model, unless otherwise specified or limited, the terms "assemble," "connect," "connect," "fix," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0028] Figures 1 to 3The utility model shows an embodiment of an online cleaning ceramic filling pump. The online cleaning ceramic filling pump of this embodiment includes a pump body 1 and a pump rod 2. The pump body 1 is provided with a first inner hole 11, a second inner hole 12 and a third inner hole 13 in sequence. The aperture of the second inner hole 12 is smaller than the apertures of the first inner hole 11 and the third inner hole 13. The pump rod 2 is provided with a first step 21, a second step 22 and a third step 23 in sequence. The diameter of the second step 22 is smaller than the diameter of the first step 21 and the third step 23. The first step 21 is adjacent to the third step 23. The two inner holes 12 are sealed together, the third step 23 is sealed together with the third inner hole 13, the length of the first inner hole 11 is greater than the length of the first step 21, the diameter of the second step 22 is smaller than the aperture of the second inner hole 12, and a gap 3 connecting the first inner hole 11 and the third inner hole 13 can be formed between the second step 22 and the second inner hole 12. A liquid inlet 14, a liquid outlet 15 and a cleaning liquid outlet 16 are provided on the pump body 1. The liquid inlet 14 and the liquid outlet 15 are both connected to the first aperture, and the cleaning liquid outlet 16 is connected to the third inner hole 13.

[0029] The working state of the online cleaning ceramic filling pump is as follows: 1) Figure 1 In the pumping state shown, the pump rod 2 moves downward, the top of the first step 21 is sealed with the second inner hole 12, and the filling liquid enters the first inner hole 11 from the liquid inlet 14; 2) as Figure 2 In the filling state shown, the pump rod 2 moves upward, the bottom end of the first step 21 is sealed with the second inner hole 12, and the filling liquid in the first inner hole 11 is discharged from the liquid outlet 15; 3) Figure 3 In the cleaning state shown, the pump rod 2 continues to move upward until the first step 21 is located in the first inner hole 11, the second step 22 is located in the second inner hole 12, the third step 23 is sealed with the third inner hole 13, and the gap 3 connects the first inner hole 11 and the third inner hole 13. At this time, the cleaning liquid is input from the liquid inlet 14, and the cleaning liquid flows through the first inner hole 11, the second inner hole 12 and the third inner hole 13 in turn, and is finally output from the cleaning liquid outlet 16 to clean the pump body 1 and the pump rod 2.

[0030] The online cleaning ceramic filling pump can realize pumping, filling and cleaning respectively through the different positional matching relationships between the step of the pump rod 2 and the inner hole of the pump body 1. The diameter of the first step 21 is smaller than the inner diameter of the first inner hole 11, and the coaxiality requirements of the two are reduced during processing, thereby reducing the processing difficulty of the pump body 1 and the pump rod 2. At the same time, the contact area and friction between the two are reduced during filling. The gap between the first step 21 and the first inner hole 11 can accommodate crystals precipitated in the filling liquid, reducing the risk of the ceramic pump being stuck after the crystals enter the space between the pump rod and the pump body. When cleaning the pump, a gap 3 connecting the first inner hole 11 and the third inner hole 13 can be formed between the second step 22 and the second inner hole 12, which facilitates the cleaning of the filling surface of the pump body 1 and the pump rod 2, further reducing the problem of pump jamming after the formation of crystals.

[0031] Furthermore, in this embodiment, the pump body 1 includes a main body 17 and a guide sleeve 18 detachably connected to the main body 17. The first inner hole 11 is disposed within the main body 17 and the guide sleeve 18. The guide sleeve 18 extends the length of the main body 17, making the length of the first inner hole 11 longer than the first step 21, thereby facilitating movement of the pump rod 2 to the cleaning position. Furthermore, the detachable connection between the guide sleeve 18 and the main body 17 accommodates pump rods 2 of varying lengths, providing strong adaptability. Preferably, the main body 17 and the guide sleeve 18 are detachably connected by a first clamp 4, resulting in a simple structure and easy assembly and disassembly.

[0032] Furthermore, in this embodiment, the first inner hole 11 includes a first sub-hole 111 and a second sub-hole 112 that are interconnected. The aperture of the first sub-hole 111 is larger than the aperture of the second sub-hole 112. The first sub-hole 111 is disposed in the guide sleeve 18, and the second sub-hole 112 is disposed in the body 17. The aperture of the first sub-hole 111 is larger than the aperture of the second sub-hole 112, which facilitates increasing the flow rate of the cleaning liquid and speeding up the cleaning speed. The first inner hole 11 is processed in sections, which also reduces the processing difficulty. In addition, since the inner diameter of the first inner hole 11 is larger than the diameter of the first step 21, the guide sleeve 18 has a higher tolerance for docking errors during installation, reducing the difficulty of installation and debugging.

[0033] Furthermore, in this embodiment, a first sealing ring 19 is provided between the body 17 and the guide sleeve 18 to ensure sealing between the body 17 and the guide sleeve 18 .

[0034] Furthermore, in this embodiment, the end of the pump rod 2 is detachably connected to a push-pull joint 24, and the third step 23 is provided on the push-pull joint 24. The push-pull joint 24 facilitates the movement of the pump rod 2. The third step 23 provided on the push-pull joint 24 can reduce the overall length of the push-pull joint 24, making the structure more compact.

[0035] Furthermore, in this embodiment, a sealing ring installation groove 25 is provided on the third step 23, and a second sealing ring 26 is provided in the sealing ring installation groove 25. In the cleaning state, the sealing between the third step 23 and the third inner hole 13 is ensured to prevent leakage of the cleaning liquid.

[0036] Furthermore, in this embodiment, the cleaning liquid outlet 16 is connected to a cleaning liquid outlet nozzle 161, which is convenient for connection with an external drain pipe.

[0037] Furthermore, in this embodiment, the pump body 1 is detachably connected to the chuck liquid nozzle 5, and the liquid inlet 14 and the liquid outlet 15 are overlapped and arranged on the chuck liquid nozzle 5. The structure is compact and the liquid outlet 15 is easy to clean.

[0038] Furthermore, in this embodiment, the pump body 1 and the chuck liquid nozzle 5 are connected by a second clamp 6, and a third sealing ring 7 is provided between the pump body 1 and the chuck liquid nozzle 5. This simple structure facilitates assembly and disassembly of the pump body 1 and the chuck liquid nozzle 5, and the third sealing ring 7 ensures a tight seal between the pump body 1 and the chuck liquid nozzle 5.
