Description

Technical Field

[0001] The utility model relates to the technical field of ceramic piston pumps, and particularly relates to a quick-disassembly valve-less ceramic pump. Background Art

[0002] In a ceramic piston pump, the pump head core is made of materials such as alumina ceramics and zirconia ceramics, which have excellent properties such as high temperature resistance, corrosion resistance, and high strength, and can be applied to the high-precision filling of most liquids with different characteristics such as corrosive, high-temperature or low-temperature liquids. The filling volume specification of a single ceramic piston pump is limited. Under the condition that the entire filling control system remains unchanged, only by replacing the "ceramic pump head" structure can the increase or decrease of the filling volume be satisfied; in addition, in order to prevent the liquid remaining in the pump body from polluting and corroding the internal structure of the pump body, it is also necessary to regularly disassemble the ceramic piston pump for cleaning.

[0003] In order to facilitate the disassembly of the "ceramic pump head" structure, a quick-disassembly structure has been designed for the ceramic piston pump in the prior art, such as the "pump head locking block" and "hand-operated nut" structures in the valve-less ceramic piston pump with the application number 201520236856.9 and the patent name, and the quick-installation structure in the "high-precision valve-less metering ceramic pump" with the application number 201810092261.9 and the patent name, as well as the clamp-type quick-installation structure in the "quick-disassembly valve-less ceramic pump" with the application number 201922100657.6 and the patent name.

[0004] For the above-mentioned structures, when removing the pump body housing, only the locking nut needs to be unscrewed and the locking block is opened to take out the pump body housing part. However, before being opened, the pin on the locking block is inserted into the matching pin hole on the housing. When the locking block is rotated to be opened, the pin is easily stuck in the pin hole, and a relatively large force needs to be applied to open the locking block, and then the pump body housing part can be taken out. In actual disassembly and replacement, a lot of effort is required, and even a wrench may be borrowed to smoothly open the locking block, which is inconvenient to operate, time-consuming and laborious, and affects work efficiency. Summary of the Utility Model

[0029] This embodiment provides a quick-disassembly valve-less ceramic pump, as Figures 1 to 5 shown, which includes a pump head 1, a driving motor 2, a pump head mounting bracket 3, a motor mounting bracket 4 and an annular clamp device 5. The pump head 1 includes a housing 6. The clamp device 5 is used to sleeved on the outer periphery of the housing 6 to detachably mount the pump head 1 on the pump head mounting bracket 3. A plunger 7 is slidably arranged in the housing 6. A liquid inlet nozzle 8 and a liquid outlet nozzle 9 are arranged on the side wall of the housing 6.

The motor mounting bracket 4 is provided with a connecting sleeve 10. The driving motor 2 is detachably mounted on the motor mounting bracket 4. The pump head mounting bracket 3 is rotatably connected to the motor mounting bracket 4, and the output shaft of the driving motor 2 and the plunger 7 of the pump head 1 are respectively connected to the connecting sleeve 10. The driving motor 2 drives the plunger 7 to reciprocate linearly for filling. A card slot 11 is arranged on the outer surface of the housing 6; the clamp device 5 includes a clamp seat 501, a first locking block 502, a second locking block 503 and a clamp handle 504. The radian of the clamp seat 501 is not greater than 180°. The clamp seat 501 is fixedly mounted on the pump head mounting bracket 3. A positioning pin 12 is arranged on the inner ring of the clamp seat 501. The first locking block 502 and the second locking block 503 are respectively located at both ends of the clamp seat 501, and both ends of the clamp seat 501 are respectively rotatably connected to one end of the first locking block 502 and the second locking block 503. The other end of the first locking block 502 is rotatably connected to the clamp handle 504. The clamp handle 504 can be clamped to the other end of the second locking block 503. When the clamp device 5 is sleeved on the outer periphery of the housing 6, the positioning pin 12 is located in the card slot 11. Among them, the clamp seat 501 is fixedly mounted on the pump head mounting bracket 3, which can be fixed after detachable connection or directly fixed such as by welding.

[0030] The utility model is provided with a clamp seat 501 with a radian not greater than 180°. A positioning pin 12 is arranged on the inner ring of the clamp seat 501. The two ends of the clamp seat 501 are respectively rotatably connected to one ends of a first locking block 502 and a second locking block 503. A clamping groove 11 is arranged on the outer surface of the housing 6. When the clamping device 5 is sleeved on the outer periphery of the housing 6, the positioning pin 12 is located in the clamping groove 11. When installing the pump head 1, after opening the first locking block 502 and the second locking block 503 to open the inner ring opening of the clamp seat 501, there is sufficient operating space to easily pass the housing 6 through the inner ring of the clamp seat 501 and make the positioning pin 12 located in the clamping groove 11, realizing the circumferential fixation of the housing 6. After installing the pump head 1, close the first locking block 502 and the second locking block 503, and rotate and lock the clamping handle 504 to make the clamping handle 504 be clamped with the other end of the second locking block 503, then the fixed installation of the pump head 1 can be completed;

[0031] When disassembling the pump head 1, rotate and loosen the clamping handle 504, then the first locking block 502 and the second locking block 503 can be easily opened, making the inner ring opening of the clamp seat 501 open, thereby ensuring sufficient operating space for the positioning pin 12 to disengage from the clamping groove 11, and then the housing 6 can be removed from the inner ring of the clamp seat 501 to complete the disassembly of the pump head 1.

[0032] It should be noted that the above-mentioned driving motor 2 is detachably installed on the motor mounting bracket 4. The output shaft of the driving motor 2 and the plunger 7 of the pump head 1 are respectively connected to the connecting sleeve 10. The driving motor 2 drives the plunger 7 to perform reciprocating linear motion for filling, which are all prior arts. For example, the content in the patent application No. 201922100657.6, the patent name is "A Valveless Ceramic Plunger Pump" and the patent application No. 201810092261.9, the patent name is "A High-Precision Valveless Quantitative Ceramic Pump", so it will not be elaborated here.

[0033] In a preferred embodiment, two card slots 11 are provided on the outer surface of the outer shell 6. The central angles of the two card slots 11 with respect to the central axis of the outer shell 6 are 90° respectively, and one of them is located on the axial plane of the liquid inlet nozzle 8 and the liquid outlet nozzle 9. To ensure smooth feeding and discharging, the axial plane of the liquid inlet nozzle 8 and the liquid outlet nozzle 9 and the axial plane of the filling volume adjusting device 22 should not form an acute angle less than 90°. Therefore, to meet different customer requirements simultaneously, it is usually necessary to ensure that the axial plane of the liquid inlet nozzle 8 and the liquid outlet nozzle 9 is parallel or perpendicular to the axial plane of the filling volume adjusting device 22. In this embodiment, when the positioning pin 12 cooperates with one of the card slots 11, the axial plane of the liquid inlet nozzle 8 and the liquid outlet nozzle 9 can be parallel to the axial plane of the filling volume adjusting device 22, and when it cooperates with the other card slot 11, the axial plane of the liquid inlet nozzle 8 and the liquid outlet nozzle 9 can be perpendicular to the axial plane of the filling volume adjusting device 22, thereby ensuring a relatively smooth feeding and discharging effect.

[0034] As Figure 3 and Figure 5 shown, an annular groove 13 is provided on the outer periphery of the outer shell 6. The clamping collar base 501, the first locking block 502, and the second locking block 503 are respectively provided with a convex ring 14. When the clamping collar handle 504 is clamped to the other end of the second locking block 503, the convex ring 14 is correspondingly clamped into the groove 13, so that the outer shell 6 and the clamping collar device 5 can be axially relatively fixed.

[0035] The card slot 11 extends along the axial direction of the outer shell 6 from one end of the outer shell 6 close to the connecting sleeve 10 to the other end. Specifically, the card slot 11 terminates at the groove 13.

[0036] In a preferred embodiment, as Figure 5 shown, the clamping collar device 5 further includes a connecting rod 505. The other end of the first locking block 502 is rotatably connected to one end of the connecting rod 505, and the other end of the connecting rod 505 is rotatably connected to the clamping collar handle 504; and / or, a through groove 15 recessed inward from its surface is provided at the other end of the second locking block 503. The second locking block 503 has an arc-shaped surface, and the arc-shaped surface forms an arc-shaped fixing groove 16. When the clamping collar handle 504 is clamped to the other end of the second locking block 503, the connecting rod 505 passes through the through groove 15, and the clamping collar handle 504 is in close contact with the fixing groove 16.

[0037] In a preferred embodiment, as Figure 1 and Figure 3 shown, an end cover 17 threadedly connected to the outer shell 6 is provided at one end of the outer shell 6 away from the connecting sleeve 10. The circumferential surface of the end cover 17 is provided with straight knurling extending along its axial direction. To facilitate screwing out the end cover 17, in the prior art, axially extending pits are provided on the end cover 17. Such pits are relatively sharp and easy to scratch hands, and will increase the outer diameter of the end cover 17. However, in this embodiment, by providing the straight knurling 18, the above situation can be avoided, and the friction can be increased and the outer diameter can be reduced, which is beneficial to reducing the total weight of the valve-less ceramic pump.

[0038] The pump head 1 further includes a cylinder barrel 19 which is sleeved between the outer shell 6 and the plunger 7. A ring-shaped first sealing ring 20 is arranged between the end cover 17 and the cylinder barrel 19. The first sealing ring 20 is used to seal the cavity space enclosed by the end cover 17, the cylinder barrel 19 and the plunger 7. In this embodiment, the end cover 17 is directly used for sealing. Compared with the prior art which still needs to additionally provide a Teflon gasket for sealing, the number of parts is reduced, the total weight of the valve-less ceramic plunger 7 pump is reduced, and the cleaning treatment of the pump head 1 is more convenient.

[0039] In another preferred embodiment, the pump head 1 further includes a cylinder barrel 19 which is sleeved between the outer shell 6 and the plunger 7. The liquid inlet nozzle 8 and the liquid outlet nozzle 9 are respectively threadedly connected to the side wall of the outer shell 6. The plunger 7 is provided with a channel port penetrating along its radial direction. The liquid inlet nozzle 8 and the liquid outlet nozzle 9 respectively abut against the end of the channel port, and second sealing rings 21 are respectively arranged between the liquid inlet nozzle 8 and the liquid outlet nozzle 9 and the plunger 7. In this embodiment, not only is it convenient to install the cylinder barrel 19, but also the liquid inlet nozzle 8 and the liquid outlet nozzle 9 with different diameters can be replaced according to the needs of the filling volume.

[0040] A filling volume adjusting device 22 is further connected between the pump head mounting bracket 3 and the motor mounting bracket 4. The filling volume adjusting device 22 includes a rotating rod 220, a screw rod 221 and an adjusting sleeve rod 222. One end of the rotating rod 220 is threadedly connected to the embedded screw rod 221, and the other end of the rotating rod 220 is embedded in the adjusting sleeve rod 222 and threadedly connected thereto. The other end of the screw rod 221 is movably connected to the pump head mounting bracket 3, and the other end of the adjusting sleeve rod 222 is movably connected to the motor mounting bracket 4. By rotating and adjusting the rotating rod 220, the included angle between the central axis of the plunger 7 and the central axis of the motor can be slightly changed, and thus the discharging or feeding amount can be slightly changed to achieve the goal of precise adjustment. One side of the clamp seat 501 facing the screw rod 221 is a plane so as to leave sufficient space for the pump head mounting bracket 3 to fix the screw rod 221.
