Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fluid delivery equipment, in particular to a quick-disassembly multi-pump. BACKGROUND

[0002] Ceramic filling pumps belong to the technical field of fluid delivery equipment, and are widely used in precision metering and the handling of corrosive or high-purity fluids. Such pumps are commonly used in industries such as chemicals, pharmaceuticals, and food processing, where there are high requirements for material corrosion resistance and cleanliness.

[0003] A ceramic filling pump mainly consists of a ceramic piston, a pump body, a driving mechanism, an inlet valve, and an outlet valve. The ceramic piston is the part that directly contacts the fluid and is made of high-performance ceramic materials such as high-purity alumina and zirconia, providing excellent corrosion resistance and wear resistance. The pump body is usually also made of corrosion-resistant materials and closely cooperates with the ceramic piston to ensure good sealing. The driving mechanism is responsible for driving the ceramic piston to perform reciprocating motion, achieving the suction and discharge of fluid. The inlet valve and outlet valve are used to control the flow of fluid into and out of the pump cavity, ensuring one-way flow of fluid.

[0004] Currently, the various components of ceramic pumps are installed through welding, multiple fastening bolts, etc. In particular, when multiple ceramic pumps are used to fill a row of products, the driving structure of each ceramic pump is installed separately, making it inconvenient to disassemble and maintain. In the medical industry, disassembly and cleaning operations are often required. SUMMARY

[0005] To improve the disassembly and maintenance convenience of ceramic pumps, the present application provides a quick-disassembly multi-pump.

[0006] The present application provides a quick-disassembly multi-pump, which adopts the following technical solutions:

[0007] The quick-disassembly multi-pump comprises:

[0008] a mounting plate;

[0009] a plurality of pump bodies are arranged on one side of the mounting plate, each of the pump bodies is provided with an outlet pipe and an inlet pipe, a flow passage is formed in each of the pump bodies, the inlet pipe and the outlet pipe are in communication with the flow passage, an insertion slot is formed at one end of each of the pump bodies, a limiting edge is arranged at the end of each of the pump bodies where the insertion slot is formed, and the limiting edge is distributed around the insertion slot.

[0010] A plurality of piston structures are provided and correspond to the pump bodies one by one, and each piston structure comprises a piston cylinder and a piston rod, one end of the piston rod is slidably arranged in the piston cylinder, and one end of the piston cylinder penetrates into the pump body and communicates with the flow passage; a snap ring is sleeved and fixedly connected outside the piston cylinder, the snap ring comprises a plurality of abutting edges, the abutting edges correspond to the limiting edges one by one, the snap ring is inserted into the insertion slot, and the abutting edges abut against the limiting edges;

[0011] A flow control member is used to control the on-off of the liquid inlet pipe and the piston cylinder, and the on-off of the liquid outlet pipe and the piston cylinder, and each pump body is communicated with the flow control member;

[0012] A driving mechanism is used to drive the piston rod to slide.

[0013] By adopting the above technical scheme, the snap ring on the piston cylinder can be quickly inserted into the insertion slot of the pump body, and fixed through the cooperation of the abutting edges and the limiting edges, thereby simplifying the installation and disassembly process between the piston structure and the pump body, facilitating daily maintenance and cleaning, and being particularly suitable for frequent disassembly requirements in the medical industry. A plurality of pump bodies and corresponding piston structures are integrated on the same mounting plate, so that the entire device is more compact, saves space, and is convenient to install and use. The flow control member is arranged on the pump body, which can accurately control the on-off of the liquid inlet pipe and the piston cylinder, and the on-off of the liquid outlet pipe and the piston cylinder, thereby ensuring the one-way flow of the fluid and improving the working efficiency and stability of the pump.

[0014] Optionally, the flow control member comprises a flow control valve body, a communication flow channel is formed in the flow control valve body, and the flow control valve body is rotationally connected to the pump body.

[0015] When the flow control valve body rotates, the communication flow channel can communicate the liquid inlet pipe with the piston cylinder, or communicate the liquid outlet pipe with the piston cylinder.

[0016] By adopting the above technical scheme, the rotation of the flow control valve body realizes the communication between the liquid inlet pipe and the piston cylinder or the communication between the liquid outlet pipe and the piston cylinder, thereby effectively controlling the flow direction of the fluid and improving the controllability and reliability of the fluid transmission.

[0017] Optionally, the flow control valve body penetrates out of the pump body at both ends, a matching clamping block is connected to one end of the flow control valve body, and a matching clamping groove for clamping the matching clamping block is formed at the other end of the flow control valve body.

[0018] The matching clamping block is clamped into the matching clamping groove of the adjacent flow control valve body, and the matching clamping block is also used to limit the relative rotation of the adjacent flow control valve body;

[0019] The mounting plate is also provided with a driving component, which is used to drive the flow control valve body to rotate.

[0020] By adopting the above technical solution, the design of the card block and the card slot not only realizes the connection between adjacent valve bodies, but also ensures the synchronous rotation between flow control valve bodies, and realizes the linkage between multiple flow control valve bodies. This allows only one drive component to control the flow control components on multiple pump bodies at the same time, simplifying the control system and improving the ease of operation.

[0021] Optionally, multiple drive mechanisms are provided, each corresponding to a piston structure;

[0022] The driving mechanism includes a driving source, a driving screw, and a driving slider. The driving slider is slidably disposed on one side of the mounting plate, and the driving screw is rotatably disposed on one side of the mounting plate. The driving screw passes through the driving slider and is threadedly connected to the driving slider. The driving source is used to drive the driving screw to rotate.

[0023] A connecting support is fixed on the drive slider, and one end of the connecting support is detachably connected to the piston rod.

[0024] By adopting the above technical solution, multiple drive mechanisms correspond one-to-one with multiple piston structures, enabling each piston structure to obtain independent and precise drive, thereby ensuring the efficient operation of the pump; the drive screw rotates to drive the drive slider to slide along the track on the mounting plate, which in turn drives the connecting support to slide to drive the piston structure to extend and retract; the detachable connection design between the connecting support and the piston rod allows for quick disassembly and reassembly when maintenance or replacement of parts is required, greatly simplifying the maintenance process, and is particularly suitable for the frequent cleaning needs of the medical industry.

[0025] Optionally, the mounting plate is provided with a guide groove, one end of the connecting support extends out of the guide groove and slides in the guide groove; each connecting support is provided with a connecting lug, and two connecting lugs are spaced apart on the connecting support, and one end of the piston rod is located between the two connecting lugs.

[0026] The connecting support is also provided with a locking pin, which passes through the connecting lug and the piston rod.

[0027] By adopting the above technical solutions, the design of the guide groove allows the connecting support to slide smoothly on the mounting plate, facilitating quick positioning and adjustment; the sliding path of the connecting support within the guide groove is limited, ensuring that the piston rod maintains linear motion during the driving process; the positioning design between the connecting lug on the connecting support and the piston rod makes the connection between the piston rod and the drive mechanism more stable; and the use of the locking pin simplifies the connection and separation process between the piston rod and the connecting support, facilitating the disassembly and maintenance of the equipment.

[0028] Optionally, the locking pin includes an abutment and a pin, with the pin passing through the connecting lug and the piston rod;

[0029] The end of the pin away from the abutment has an anti-disengagement component, which includes an interlocking rod section and an abutment rod section connected to each other. The interlocking rod section passes through the pin, and the abutment rod section abuts against the pin. The abutment rod section is made of elastic material.

[0030] By adopting the above technical solution, the use of the anti-detachment component further improves the safety of the connection, prevents the pin from accidentally coming out, and ensures the stability and safety of equipment operation. Specifically, the insertion rod section passes through the pin; when the pin becomes loose, the insertion rod abuts against the connecting ear plate, preventing the pin from detaching from the connecting ear plate; the abutting rod section presses against the pin, allowing the abutting rod section to cooperate with the insertion rod section to clamp the pin, thus achieving stable installation of the anti-detachment component on the pin.

[0031] Optionally, each of the connected flow channels is slidably provided with a descaling brush, the descaling brush including a brush rod, both ends of the brush rod being located outside the flow control valve body, and the length direction of the brush rod being parallel to the rotation axis of the flow control valve body;

[0032] In two adjacent descaling brushes, one end of the brush rod is detachably connected to the other brush rod.

[0033] By adopting the above technical solution, descaling brushes are slidably installed in each connecting flow channel. The reciprocating sliding of these brushes effectively removes residues from the flow channels, preventing blockages and extending the equipment's service life. The length of the brush rod is parallel to the rotation axis of the flow control valve body, allowing the descaling brushes to move synchronously with the valve body as it rotates, ensuring the valve body's normal operation. In two adjacent descaling brushes, one end of the brush rod is detachably connected to the other, facilitating disassembly and maintenance and reducing cleaning costs.

[0034] Optionally, one end of the brush rod is provided with a first magnetic block and the other end is provided with a second magnetic block, and the first magnetic block and the second magnetic block can attract each other.

[0035] By adopting the above technical solution, the arrangement of the first and second magnetic blocks allows adjacent brush rods to attract each other, thus forming a continuous cleaning structure. At the same time, the magnetic connection method simplifies the maintenance process and reduces disassembly and assembly time, making it particularly suitable for applications requiring frequent cleaning and maintenance.

[0036] Optionally, each of the pump bodies is fixed with a drain pipe, which is connected to the connecting flow channel;

[0037] A sludge collection pipe is also provided below the flow control valve body, and each of the drain pipes is connected to the sludge collection pipe.

[0038] By adopting the above technical solution, the drain pipes on each flow control valve body are connected to the connecting flow channels. During the cleaning process using a descaling brush, impurities and dirt in the connecting flow channels can be discharged in a timely manner, keeping the flow channels clean and reducing the risk of blockage. At the same time, the sludge collection pipe installed below the flow control valve body collects the dirt from each drain pipe, facilitating centralized treatment and improving the system's hygiene performance and maintenance convenience.

[0039] In summary, this application includes at least one of the following beneficial effects:

[0040] 1. By setting an insertion groove and a limiting edge at one end of the pump body, and connecting a retaining ring and an abutment edge to both piston cylinders, the piston structure can be quickly inserted and removed, which significantly improves the ease of disassembly and assembly of the ceramic pump, making it particularly suitable for the regular disassembly and cleaning needs of the medical industry.

[0041] 2. The integrated design of multiple pump bodies and piston structures on the mounting plate allows multiple ceramic pumps to be installed and disassembled simultaneously, reducing disassembly and assembly time and labor costs, and improving overall work efficiency;

[0042] 3. The design of the flow control device can effectively control the opening and closing of the inlet and outlet pipes, ensuring unidirectional fluid flow. At the same time, through the rotational connection of the flow control valve body and the limiting effect of the locking block, synchronous control between multiple pump bodies is achieved, enhancing the reliability and stability of the system.

[0051] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0052] Example 1:

[0053] Reference Figure 1 and Figure 2 The quick-release multi-unit pump provided in this application embodiment includes a mounting plate 1, a pump body 2, a piston structure 3, a flow control element 4, and a drive mechanism 5. Multiple pump bodies 2 are fixedly connected to one side of the mounting plate 1 by bolts, and the multiple pump bodies 2 are evenly spaced; in this embodiment, five pump bodies 2 are specifically provided. An outlet pipe 21 and an inlet pipe 22 are fixedly connected to the pump body 2, with the axis of the outlet pipe 21 perpendicular to the axis of the inlet pipe 22. A flow passage 23 and an inlet channel 26 are provided inside the pump body 2, with the inlet channel 26 perpendicular to the flow passage 23; one end of the flow passage 23 communicates with the outlet pipe 21, and one end of the inlet channel 26 communicates with the flow passage 23, while the other end communicates with the inlet pipe 22.

[0054] Reference Figure 2 and Figure 3Each pump body 2 is connected to a flow control element 4, which includes a flow control valve body 41 and a mating block 42 fixedly connected to one end of the flow control valve body 41. The flow control valve body 41 passes through the middle of the pump body 2, and both ends of the flow control valve body 41 are located outside the pump body 2; the flow control valve body 41 is rotatably and sealingly connected to the pump body 2. The flow control valve body 41 is specifically cylindrical, and the diameter of the flow control valve body 41 is larger than the inner diameter of the flow passage 23 and the liquid inlet passage 26. A connecting flow channel 411 is provided on the flow control valve body 41, which in this embodiment is specifically "V" shaped. A mating groove 412 is provided at the end of the flow control valve body 41 away from the mating block 42, which in this embodiment is specifically strip-shaped. In two adjacent flow control elements 4, the mating block 42 on one flow control element 4 engages with the mating groove 412 of the adjacent flow control element 4. Achieve snap-fit ​​connection between adjacent flow control components 4.

[0055] Reference Figure 1 A drive unit 10 is also fixedly connected to the mounting plate 1. The drive unit 10 is specifically configured as a servo motor. The output shaft of the drive unit 10 is inserted and engaged with a mating block 42 of a flow control component 4. Activating the drive unit 10 will drive all flow control valve bodies 41 on the mounting plate 1 to rotate. In other embodiments, the mating slot 412 may also be configured as other polygonal slots.

[0056] Reference Figure 3 and Figure 4 The pump body 2 has an insertion groove 24 at one end, which is connected to the flow channel 23. A limiting edge 25 is provided at the end of the pump body 2 with the insertion groove 24, and the limiting edges 25 are distributed around the periphery of the insertion groove 24. In this embodiment, the limiting edges 25 are integrally formed on the end wall of the pump body 2, and two limiting edges 25 are spaced apart. The piston structure 3 includes a piston cylinder 31 and a piston rod 32. One end of the piston rod 32 is slidably disposed inside the piston cylinder 31, and the other end of the piston rod 32 passes into the pump body 2 and is connected to the flow channel 23. A retaining ring 311 is fitted and fixed outside the piston cylinder 31. In this embodiment, the retaining ring 311 is integrally formed outside the piston cylinder 31. The retaining ring 311 includes two abutment edges 3111, which correspond one-to-one with the limiting edges 25. The retaining ring 311 is inserted into the insertion groove 24, and the abutment edges 3111 abut against the limiting edges 25. In this embodiment, the abutment edge 3111 is specifically designed as an arc-shaped strip. When it is necessary to disassemble the piston structure 3 and the pump body 2, the piston cylinder 31 is rotated to cause the limiting edge 25 to misalign with the abutment edge 3111, thereby removing the retaining ring 311 from the retaining groove and moving it away from the piston cylinder 31. This achieves the purpose of quick disassembly and assembly, facilitating maintenance and cleaning.

[0057] Reference Figure 2During operation, pump body 2 has two states: a discharge state and a replenishment state. In the replenishment state, the flow control valve body 41 rotates, connecting the inlet channel 26 and the piston cylinder 31 via the connecting channel 411, allowing liquid to be replenished from the inlet pipe 22 into the piston cylinder 31. In the discharge state, the flow control valve body 41 rotates, connecting the outlet pipe 21 and the piston cylinder 31 via the connecting channel 411. The piston rod 32 slides towards the pump body 2, driving the liquid in the piston cylinder 31 to flow towards the outlet pipe 21 and be discharged along the outlet pipe 21.

[0058] Reference Figure 1 and Figure 2 Multiple drive mechanisms 5 are also provided, and each drive mechanism 5 corresponds one-to-one with the piston structure 3. Each drive mechanism 5 includes a drive source 51, a transmission assembly 54, a drive screw 52, ​​and a drive slider 53. A support bracket 11 and a connecting plate 12 are fixedly connected to the side of the mounting plate 1 facing away from the pump body 2, with the support bracket 11 and connecting plate 12 spaced apart. One end of the drive screw 52 passes through the support bracket 11 and is rotatably connected to it, while the other end is rotatably connected to the connecting plate 12 via a bearing. The drive slider 53 is located between the support bracket 11 and the connecting plate 12, and the drive screw 52 passes through and is threadedly connected to the drive slider 53. A guide rod 13 is provided above the drive screw 52, ​​parallel to the drive screw 52, ​​and passes through the drive slider 53. The transmission assembly 54 is mounted on the support bracket 11 and can be configured as a belt drive assembly, gear set, etc. In this embodiment, the transmission assembly 54 is specifically configured as a belt drive assembly 54, and the drive source 51 is specifically configured as a servo motor. The transmission assembly 54 includes two pulleys 541 and a transmission belt 542 sleeved around the two pulleys 541. One pulley 541 is coaxially fixed to the output shaft of the drive source 51, and the other pulley 541 is coaxially fixed to one end of the drive screw 52. When the drive source 51 is started, the drive slider 53 can be driven to slide along the guide rod 13.

[0059] Reference Figure 2 and Figure 5A connecting support 531 is fixed on the drive slider 53. A guide groove 14 is provided on the mounting plate 1, and multiple guide grooves are provided corresponding to the drive mechanism 5. One end of the connecting support 531 extends out of the corresponding guide groove 14 and slides within it. A connecting ear plate 5311 is integrally formed at the end of the connecting support 531 extending out of the guide groove 14. Two connecting ear plates 5311 are spaced apart, and one end of the piston rod 32 is engaged between the two connecting ear plates 5311. A locking pin 6 is also provided on the connecting support 531. The locking pin 6 includes a mutually fixed abutment part 61 and a pin 62. The pin 62 passes through the two connecting ear plates 5311 and the piston rod 32, and the axis of the pin 62 is perpendicular to the length direction of the piston rod 32. The pin 62 can also extend from the ends of the connecting ear plates 5311 and the piston rod 32, allowing for a detachable connection between the connecting support 531 and one end of the piston rod 32 via the locking pin 6.

[0060] After the drive source 51 is started, the drive screw 52 rotates under the combined action of the drive source 51 and the transmission assembly 54, thereby driving the drive slider 53 to move along the mounting plate 1, and then pushing the piston rod 32 to slide, so as to realize the intake and discharge of fluid in the pump body 2.

[0061] Reference Figure 5 To further enhance the stability of the connection between the support 531 and the piston rod 32, an anti-disengagement component 7 is provided at the end of the pin 62 away from the abutment portion 61. The anti-disengagement component 7 includes an interlocking insertion rod segment 71 and an abutment rod segment 72. In this embodiment, the insertion rod segment 71 and the abutment rod segment 72 are integrally formed and made of an elastic material. The insertion rod segment 71 passes through the pin 62, and the abutment rod segment 72 abuts against the outer wall of the pin 62.

[0062] The implementation principle of the quick-release multi-unit pump in this embodiment 1 is as follows: A suitable number of pump bodies 2 and drive mechanisms 5 are installed in the form of a mounting plate 1 as needed. The flow control valve bodies 41 of adjacent pump bodies 2 are connected by a locking block 42. When installing the piston structure 3 on the pump body 2, one end of the piston cylinder 31 is aligned with the insertion groove 24. After the abutment edge 3111 on the retaining ring 311 is misaligned with the limiting edge 25 on the corresponding pump body 2, the retaining ring is inserted into the insertion groove 24. Then, the piston cylinder 31 is rotated so that the abutment edge 3111 abuts against the limiting edge 25, thus achieving the connection between the piston structure 3 and the pump body 2. Subsequently, the end of the piston rod 32 away from the pump body 2 is locked between the two connecting lugs 5311 of the corresponding connecting support 531. A locking pin 6 is inserted through the connecting lugs 5311 and the piston rod 32, and then an anti-disengagement component 7 is used to further lock the locking pin 6, achieving a stable connection between the piston rod 32 and the end of the connecting support 531.

[0063] Example 2:

[0064] The difference between this embodiment and the above embodiments is that: (Refer to...)Figure 6 and Figure 7 In this embodiment, each flow control valve body 41 is connected to a descaling brush 8, which slides within the connecting flow channel 411 of the flow control valve body 41. The descaling brush 8 includes a brush rod 81 and bristle bodies 82 fixed to the brush rod 81. The cross-section of the bristle body 82 is the same as the cross-sectional shape of the connecting flow channel 411. A receiving cavity 413 is provided inside the flow control valve body 41, and the bristle body 82 slides within the receiving cavity 413, which is connected to the connecting flow channel 411. Both ends of the brush rod 81 are located outside the flow control valve body 41, and the length direction of the brush rod 81 is parallel to the rotation axis of the flow control valve body 41. The cross-section of the brush rod 81 is specifically rectangular. In this embodiment, no mating block 42 or mating groove 412 is provided. One end of the brush rod 81 is fixed with a first magnetic block 83, and the other end is fixed with a second magnetic block 84. In two adjacent descaling brushes 8, one end of one brush rod 81 and the other brush rod 81 can be attracted to each other through the first magnetic block 83 and the second magnetic block 84, so as to realize the detachable connection between adjacent descaling brushes 8.

[0065] Reference Figure 7 The flow control valve body 41 is equipped with a brush rod 81 on the pump body 2 furthest from the drive member 10 when cleaning is required. This allows all the brush bristles 82 to slide back and forth within the corresponding receiving cavity 413 of the pump body 2, cleaning the dirt adhering to the inner wall of the flow channel 411 and ensuring smooth flow of fluid within the pump body 2. When cleaning the flow channel 411 is not required, the brush rod 81 can be slid to move the brush bristles to the end of the receiving cavity 413 without interfering with the normal use of the flow channel 411. In other embodiments, an electric push rod can be connected to the brush rod 81 on the pump body 2 furthest from the drive member 10 to achieve an automatic cleaning function.

[0066] Specifically, the brush handle 81 can be made of stainless steel or nylon, which has good wear resistance and corrosion resistance. The brush on the brush handle 81 can be made of nylon filaments or steel wire, which has good cleaning effect. The first magnetic block 83 and the second magnetic block 84 can be neodymium iron boron magnets, which have strong magnetism and ensure stable connection of the descaling brush 8.

[0067] Reference Figure 6 and Figure 7Each pump body 2 is also equipped with a drain pipe 43, one end of which extends into the pump body 2 and connects to the connecting flow channel 411. A collection pipe 9 is also provided below the flow control valve body 41, and the end of each drain pipe 43 furthest from the flow control valve body is connected to the collection pipe 9. Impurities and dirt removed during cleaning with the descaling brush 8 can be discharged along the drain pipe 43, keeping the connecting flow channel 411 clean and reducing the risk of blockage. Simultaneously, the collection pipe 9 below the flow control valve body 41 collects dirt from each drain pipe 43 for centralized treatment. A shut-off valve 431 is also installed on the drain pipe 43 to control the connection and disconnection between the drain pipe 43 and the collection pipe 9. In this embodiment, the drain pipe 43 passes through the pump body 2 and connects to the receiving cavity 413, and two drain pipes 43 are fixed on one pump body 2.

[0068] The implementation principle of the quick-release multi-unit pump in this embodiment 2 is as follows:

[0069] By installing a descaling brush 8 within the connecting channel 411 of the flow control valve body 41, impurities within the channel 411 can be periodically cleaned during use, preventing blockages. The descaling brush 8 is connected to the first magnetic block 83 and the second magnetic block 84 at both ends of the brush rod 81, allowing for easy disassembly and replacement. As the descaling brush 8 slides within the flow control valve body 41, it effectively removes deposits from the channel. The design of the drain pipe 43 and the collection pipe 9 allows for the centralized collection of the cleaned impurities, facilitating subsequent processing. The entire system has a compact structure and is easy to operate, improving system reliability and extending its service life.

[0070] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
