Description

Technical Field

[0001] The present application relates to the field of electromagnetic pump technology, and in particular to a composite integrated non-porous diaphragm type mechanical electromagnetic pump. Background Art

[0002] The diaphragm electromagnetic pump is a pump powered by electromagnetic force. The electromagnetic force causes the diaphragm to vibrate, thereby achieving liquid transportation. It is mainly composed of an electromagnet, a diaphragm and a drive device. The diaphragm electromagnetic pump has the advantages of simple structure, no leakage, and reliable operation. It is suitable for transporting various chemicals, corrosive media and viscous liquids. In industrial production, it is widely used in chemical, metallurgical, pharmaceutical and other fields.

[0003] However, for most diaphragm electromagnetic pumps in the prior art, their structure is mainly spliced, that is, several or several parts are installed together by splicing. Although this structure can well disassemble and repair the diaphragm electromagnetic pump, it will seriously reduce the airtightness of the diaphragm electromagnetic pump, resulting in a significant decrease in the working efficiency of the diaphragm electromagnetic pump. Utility Model Content

[0004] In order to improve the electromagnetic pump structure in the prior art, which is composed of spliced ​​structures, resulting in a serious decrease in air tightness and thus low working efficiency of the electromagnetic pump, the present application provides a composite integrated non-porous diaphragm type mechanical electromagnetic pump.

[0005] The present application provides a composite integrated non-porous diaphragm type mechanical electromagnetic pump adopts the following technical solution:

[0006] A composite integrated non-porous diaphragm type mechanical electromagnetic pump, comprising a support tube with a volume cavity opened inside, a liquid inlet pipe and a liquid outlet pipe installed side by side at the same end of the support tube, an air pump installed at the end of the support tube away from the liquid inlet pipe and the liquid outlet pipe, and a coil fixedly mounted on the support tube, the liquid inlet pipe and the liquid outlet pipe are both connected to the volume cavity, and the support tube is respectively provided with a first control mechanism and a second control mechanism at positions close to the liquid inlet pipe and the liquid outlet pipe, a diaphragm is slidably arranged in the volume cavity, the diaphragm includes an elastic membrane located in the middle and a ferromagnetic magnetic ring fixedly connected to the edge of the elastic membrane, an air cavity is opened in the support tube, the air cavity is located on the side of the diaphragm away from the liquid inlet pipe, and the air pump is connected to the air cavity.

[0007] By adopting the above technical scheme, when liquid is inletted, the first control mechanism can be used to control the liquid to enter the volume chamber. In this process, the coil is energized to generate electromagnetic force and adsorb the magnetic ring and the elastic membrane to slide in the volume chamber to the side away from the liquid inlet pipe. At this time, the volume of the liquid that can be accommodated in the volume chamber reaches the maximum, and the air pump draws gas from the air chamber to reduce the pressure on the side of the elastic membrane away from the liquid inlet pipe. The atmospheric pressure allows the liquid to enter the volume chamber more smoothly. When liquid is out, the second control mechanism controls the opening of the liquid outlet pipe. At this time, the air pump inflates the air chamber so that the diaphragm can move toward the liquid outlet pipe, pushing the liquid out of the volume chamber, thereby improving the capacity and working efficiency of the electromagnetic pump.

[0008] Optionally, a side fixing sleeve of the magnetic ring is provided with a rubber ring for preventing gas or liquid from passing through, and the axial width of the rubber ring is greater than the axial width of the magnetic ring.

[0009] By adopting the above technical solution, it is possible to prevent the liquid from entering the air cavity through the gap at the edge of the magnetic ring when in the volume cavity, and it is also possible to prevent the air in the air cavity from entering the volume cavity, thereby ensuring the dryness of the air cavity. At the same time, the width of the rubber ring is greater than the width of the magnetic ring in order to provide protection for the magnetic ring, thereby preventing the magnetic ring from colliding with the inner walls at both ends of the volume cavity during sliding, thereby causing damage to the magnetic ring.

[0010] Optionally, the support tube is provided with a liquid inlet cavity connected to the liquid inlet pipe, the air cavity is provided with a first passage connected to the liquid inlet cavity, the first control mechanism includes a first soft rubber tube fixedly installed in the liquid inlet cavity and a first valve body installed at the first passage position on the side wall of the air cavity, the first soft rubber tube is coaxial with the liquid inlet pipe, the first soft rubber tube is elastic, and both ends of the first soft rubber tube are sealed.

[0011] By adopting the above technical solution, when liquid is introduced, the first valve body opens and the air in the liquid inlet chamber is extracted through the first passage. At this time, the external air pressure is greater than the air pressure inside the liquid inlet chamber, and the liquid can smoothly enter the volume chamber through the first soft rubber tube. When liquid is discharged, the air pump inflates the air cavity, the first passage and the liquid inlet chamber, and the first soft rubber tube is subjected to an axial squeezing force, thereby closing the liquid inlet pipe. This structure can avoid the installation of a separately driven control mechanism at the position of the liquid inlet pipe, which increases the cost and structural complexity of the electromagnetic pump.

[0012] Optionally, the support tube is provided with a liquid outlet cavity connected to the liquid outlet pipe, the air cavity is provided with a second passage connected to the liquid outlet cavity, the side wall of the support tube is provided with an air outlet connected to the second passage, and the second control mechanism includes a second soft rubber tube fixedly installed inside the liquid outlet cavity and a second valve body arranged at the connecting position of the second passage and the air outlet and used for controlling the opening and closing of the second passage and the air outlet.

[0013] By adopting the above technical solution, when liquid is introduced, a part of the air extracted from the air cavity by the air pump enters the second passage and the liquid outlet cavity, so that the second soft rubber tube is blocked by the extrusion force, preventing the liquid from flowing out. When liquid is discharged, the second passage is connected to the air outlet through the second valve body. At this time, the external air pressure is the same as the air pressure inside the liquid outlet cavity, so the liquid can be discharged smoothly. The operation is simple and easy to implement.

[0014] Optionally, an adjustment cylinder is slidably arranged inside the air cavity, and one end of the adjustment cylinder is integrally connected with an abutment ring slidably arranged in the volume cavity, the adjustment cylinder is airtightly matched with the side wall of the volume cavity and the side wall of the air cavity, an adjustment rod is fixedly connected to the side of the abutment ring away from the diaphragm, and one end of the adjustment rod away from the abutment ring slides out of the support cylinder, and an adjustment part is provided on the support cylinder to facilitate adjusting the position of the adjustment rod.

[0015] By adopting the above technical solution, the position of the adjusting cylinder in the air cavity can be adjusted by rotating the adjusting rod, so as to adjust the volume cavity and the volume of the air cavity, and indirectly adjust the speed of the electromagnetic pump to absorb and release the liquid. At the same time, the change of the size of the air cavity can also increase or decrease the power of the electromagnetic pump to absorb the liquid, and has a wider range of applications for different liquids.

[0016] Optionally, the adjusting member is a threaded sleeve detachably disposed on the supporting tube, and the threaded sleeve is connected to the internal thread of the adjusting rod.

[0017] By adopting the above technical solution, the threaded connection between the threaded sleeve and the adjusting rod can realize the precise adjustment of the position of the adjusting cylinder in the volume chamber. In addition, the detachable connection between the threaded sleeve and the support cylinder is designed to facilitate the rapid adjustment of the adjusting rod by disassembling the threaded sleeve when necessary, thereby avoiding the situation where the adjustment speed is too slow and the working efficiency of the electromagnetic pump is reduced when the liquid inlet and outlet speed or the liquid release pressure inside the electromagnetic pump needs to be quickly adjusted.

[0018] Optionally, a return spring is fixedly provided on a side of the abutment ring close to the diaphragm, and one end of the return spring away from the abutment ring abuts against the magnetic ring.

[0019] By adopting the above technical solution, the driving force of the diaphragm when pushing the liquid inside the volume cavity out of the discharge pipe can be increased, and the diaphragm can be automatically reset after the electromagnetic pump completes its work, so as to facilitate the next use.

[0020] Optionally, the diameter of the air cavity along the cross section is equal to the diameter of the inner side of the magnetic ring along the cross section.

[0021] By adopting the above technical solution, it is possible to avoid friction between the elastic membrane and the end of the air cavity when the elastic membrane bends toward the air cavity due to the low air pressure inside the air cavity, thereby avoiding damage to the elastic membrane structure that may be caused by multiple frictions.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. This application designs a new integrated non-porous diaphragm electromagnetic pump, which has a better sealing effect than the electromagnetic pump assembled from multiple parts in the prior art, and can effectively improve the working efficiency of the electromagnetic pump;

[0024] 2. The composite integrated non-porous diaphragm electromagnetic pump of the present application can adjust the suction capacity of the pump body and the suction and release speeds according to different actual usage scenarios;

[0025] 3. The opening and closing of the liquid inlet and outlet pipes of the electromagnetic pump of the present application are controlled by the control valve body through air pressure regulation, which can avoid the need to install a control mechanism with a drive structure at the liquid inlet and outlet positions, and can simplify the overall structure of the pump body.

[0035] The following is combined with Figure 1-8 This application is described in further detail.

[0036] The embodiment of the present application discloses a composite integrated non-porous diaphragm type mechanical electromagnetic pump.

[0037] Reference Figure 1 , Figure 2 and Figure 3 A composite integrated non-porous diaphragm electromagnetic pump includes a support tube 1 with a volume cavity 11 formed inside and used to support the entire pump body structure, a liquid inlet pipe 2 and a liquid outlet pipe 3 fixedly mounted on one side of the support tube 1, an air pump 4 fixedly arranged on the support tube 1 at one end away from the liquid inlet pipe 2 and the liquid outlet pipe 3, and a coil 5 fixedly sleeved on the outside of the support tube 1. The diameter of the side of the support tube 1 where the coil 5 is sleeved is smaller than the diameter of the entire support tube 1. The liquid inlet pipe 2 and the liquid outlet pipe 3 have the same appearance and are arranged side by side at the same end of the support tube 1.

[0038] Reference Figure 3 , Figure 4 and Figure 5 The liquid inlet pipe 2 and the liquid outlet pipe 3 are both connected to the volume chamber 11 in the support tube 1, and the first control mechanism 6 and the second control mechanism 7 for limiting the liquid entering and exiting the volume chamber 11 are respectively arranged at the positions of the liquid inlet pipe 2 and the liquid outlet pipe 3 near the volume chamber 11 inside the support tube 1. A diaphragm 8 is arranged inside the volume chamber 11, which can slide along the axis of the volume chamber 11 in the volume chamber 11, and the diaphragm 8 includes an elastic film 81 with elasticity located in the middle, and a magnetic ring 82 installed on the circumferential edge of the elastic film 81. The magnetic ring 82 has ferromagnetism and can move along the direction of the magnetic force when the coil 5 generates magnetic force.

[0039] Reference Figure 3 and Figure 4 The support tube 1 has an air cavity 12 in communication with the volume cavity 11 and coaxial with the volume cavity 11. The diameter of the air cavity 12 along the cross section is smaller than the diameter of the volume cavity 11 along the cross section, so as to limit the sliding of the diaphragm 8 along the axial direction and prevent the diaphragm 8 from sliding into the air cavity 12 and failing to be smoothly driven by the electromagnetic force.

[0040] Reference Figure 3 and Figure 4 Furthermore, the diameter of the air cavity 12 along the cross section is equal to the diameter of the inner wall of the magnetic ring 82 along the cross section, that is, when the elastic membrane 81 bends toward the air cavity 12, it will not rub against the end of the air cavity 12. The main purpose of this design is to protect the elastic membrane 81 from being damaged after repeated use.

[0041] Reference Figure 3 and Figure 4 Furthermore, a rubber ring 821 is fixedly sleeved on the outer edge of the magnetic ring 82, and the rubber ring 821 is in sliding contact with the inner wall of the volume chamber 11. The rubber ring 821 is provided in this design to separate the two sides of the diaphragm 8 and achieve a sealing effect to prevent the liquid in the volume chamber 11 or the gas in the air chamber 12 from entering the other chamber. In addition, the axial width of the rubber ring 821 is designed to be greater than the axial width of the magnetic ring 82, so that when the diaphragm 8 slides in the volume chamber 11, it will not collide with the side walls at both ends of the volume chamber 11 to damage the magnetic ring 82.

[0042] Reference Figure 3 and Figure 6 The support tube 1 is provided with a liquid inlet cavity 13 coaxial with the liquid inlet tube 2 near the liquid inlet tube 2. The support tube 1 is provided with a first passage 14 connecting the air cavity 12 and the liquid inlet cavity 13. The first control mechanism 6 includes a first valve body 61 provided at the connection position between the first passage 14 and the air cavity 12, and a first soft rubber tube 62 axially installed in the liquid inlet cavity 13 and coaxial with the liquid inlet tube 2. Both ends of the first soft rubber tube 62 are fixedly connected and sealed to the inner side walls of the liquid inlet cavity 13 at both ends along the axial direction.

[0043] Reference Figure 3 and Figure 6 The support tube 1 is provided with a liquid outlet cavity 15 at the position of the liquid outlet pipe 3, and the liquid outlet cavity 15 is connected with a second passage 16, and one end of the second passage 16 away from the liquid outlet cavity 15 is also connected with the gas cavity 12. At the same time, the second passage 16 is also connected with an air outlet 17 opened on the support tube 1 and connected with the outside. The second control mechanism 7 includes a second valve body 71 arranged at the position where the second passage 16 is connected with the air outlet 17, and a second soft rubber tube 72 fixedly installed in the liquid outlet cavity 15, and the installation method of the second soft rubber tube 72 is the same as that of the first soft rubber tube 62.

[0044] Reference Figure 7Furthermore, an axially slidable adjusting cylinder 9 is provided in the air cavity 12. An end of the adjusting cylinder 9 close to the diaphragm 8 is fixedly connected to an abutment ring 91 movably provided inside the volume cavity 11, and the edge of the abutment ring 91 abuts against the inner wall of the volume cavity 11. An adjusting rod 92 axially extending through the support cylinder 1 is integrally connected to the side of the abutment ring 91 away from the diaphragm 8, so as to adjust the volume of the volume cavity 11. At the same time, due to the change in the volume of the volume cavity 11, the axial stroke of the diaphragm 8 and the volume of gas that can be accommodated in the air cavity 12 will also change, thereby affecting the power of the electromagnetic pump to absorb liquid and the working speed of the electromagnetic pump.

[0045] More specifically, the regulating cylinder 9 is airtightly connected to the volume chamber 11 and the air chamber 12 to prevent the air in the air chamber 12 from escaping during the sliding of the regulating cylinder 9, thereby preventing the electromagnetic pump from working properly.

[0046] Reference Figure 7 and Figure 8 Furthermore, one end of the adjusting rod 92 extending out of the supporting tube 1 is provided with an adjusting piece 93 which is detachably arranged on the end of the supporting tube 1, so as to accurately adjust the position of the adjusting rod 92 and the adjusting tube 9 which is integrally connected with the adjusting rod 92, so as to realize accurate control of the liquid absorption power of the electromagnetic pump and the liquid volume that the volume chamber 11 can accommodate.

[0047] Reference Figure 3 and Figure 7 Specifically, the adjusting member 93 is a threaded sleeve 931 with a threaded inner ring. The end of the adjusting rod 92 extends out of the threaded sleeve 931, and the adjusting rod 92 is threadedly connected to the threaded sleeve 931. It is worth mentioning that the threaded sleeve 931 is used in this design only because the threaded sleeve 931 meets the functional requirements of the adjusting member 93 of this design, and the adjusting member 93 is not limited thereto. Therefore, any parts or mechanical mechanisms that meet the functional requirements of the adjusting member 93 of this design should be included in the protection scope of this application.

[0048] Reference Figure 7 and Figure 8 A return spring 911 is fixedly mounted on the side of the abutting ring 91 close to the diaphragm 8, and one end of the return spring 911 away from the abutting ring 91 abuts against the magnetic ring 82, so that when the electromagnetic pump finishes working, the diaphragm 8 can be reset. At the same time, the return spring 911 can also increase the power of the diaphragm 8 to push the liquid out of the electromagnetic pump, thereby improving the working efficiency of the electromagnetic pump.

[0049] The implementation principle of a composite integrated non-porous diaphragm type mechanical electromagnetic pump in the embodiment of the present application is:

[0050] The first control mechanism 6 and the second control mechanism 7 work together, so that when the electromagnetic pump is started, the air pump 4 inflates the air cavity 12, and the return spring 911 abuts against the magnetic ring 82, pushing the diaphragm 8 to move toward the liquid inlet pipe 2. In this process, the first valve body 61 and the second valve body 71 are both opened, so that the air pressure in the liquid inlet cavity 13 and the liquid outlet cavity 15 increases, respectively squeezing the first soft rubber tube 62 and the second soft rubber tube 72, so that the two are closed.

[0051] When the electromagnetic pump sucks liquid, the second valve body 71 is closed and the first valve body 61 is opened, at which time the coil 5 is energized and attracts the diaphragm 8 to move toward the air cavity 12. At the same time, the air pump 4 sucks the gas in the air cavity 12, causing the elastic membrane 81 to bend toward the air cavity 12. The liquid is pressed into the volume cavity 11 under the action of atmospheric pressure.

[0052] When the electromagnetic pump releases liquid, the air pump 4 inflates the air cavity 12, pushing the diaphragm 8 to slide toward the liquid outlet pipe 3. In this process, the first valve body 61 is closed after the liquid inlet chamber 13 reaches sufficient air pressure, and the first soft rubber tube 62 is affected by the air pressure, and the passage connecting the liquid inlet pipe 2 and the volume chamber 11 is closed. At the same time, the second valve body 71 is closed, and the air outlet 17 is connected to the liquid outlet chamber 15. At this time, the air pressure inside and outside the second soft rubber tube 72 is equal, forming a passage between the liquid outlet pipe 3 and the volume chamber 11, so that the liquid is smoothly discharged from the electromagnetic pump under the push of the diaphragm 8.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
