[0029] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the accompanying drawings of the specification.

[0030] In the following description, many specific details are set forth to facilitate a thorough understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0031] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0032] By Figure 1 and Figure 2As shown in the figure, it is a schematic structural diagram of the fluoroplastic magnetic pump in this embodiment. The magnetic pump includes a mounting base 1, a magnetic pump main body 2, a delivery chamber 3, and an agitation impeller 4. The magnetic pump main body 2 is mounted on the surface of the mounting base 1, and the delivery chamber 3 is mounted on the side of the magnetic pump main body 2. The delivery chamber 3 is composed of a rotating cylinder and a conical guide cylinder. The rotating cylinder is mounted at the end of the magnetic pump main body 2 through a connecting flange, and the conical guide cylinder is mounted at the opening of the rotating cylinder. The side opening of the conical guide cylinder serves as the input port for the medium, and the top opening of the rotating cylinder serves as the output port for the medium. An agitation impeller 4 for driving the medium to flow is mounted in the delivery chamber 3.

[0033] During use, a motor is mounted at the end of the magnetic pump main body 2 to provide power for the outer rotor inside the magnetic pump main body 2. Then, under the action of the magnetic field, the outer rotor drives the inner rotor to rotate, providing power for the operation of the agitation impeller 4. When the agitation impeller 4 rotates, the internal pressure of the delivery chamber 3 changes, absorbing the medium at the side opening of the delivery chamber 3. Then, under the action of centrifugal force, the medium flows out through the component at the top of the rotating cylinder, realizing the delivery and extraction of the medium. Moreover, the key components of the agitation impeller 4 and the delivery chamber 3 are made of fluoroplastic material, which can effectively prevent the corrosion of the medium itself, improve the stability during the operation of the equipment, and a delivery pump 7 is mounted outside the magnetic pump main body 2, which can circulate and extract the cooling lubricating oil inside the magnetic pump main body 2 for use, reducing the overall temperature of the magnetic pump main body 2.

[0034] A control assembly for controlling the flow rate of the medium is mounted on the delivery chamber 3. The control assembly is composed of a control mechanism 5 and a shielding mechanism 6.

[0035] By attachment Figure 3 As shown in the figure, it is a schematic structural diagram of the control mechanism 5 in this embodiment. The control mechanism 5 includes a flow-through pipe body 51, a ball valve main body 52, a control connecting rod 53, a control handle 54, and a flange 55. Flow-through pipe bodies 51 are mounted at both the side opening and the top opening of the delivery chamber 3. The flow-through pipe body 51 is a tubular structure with openings at both the top and bottom. A total of two groups of flow-through pipe bodies 51 are provided. One group is mounted at the side opening of the delivery chamber 3 as the input pipe, and the other group is mounted at the top opening of the delivery chamber 3 as the output pipe. A ball valve main body 52 for controlling the flow rate of the medium inside the flow-through pipe body 51 is mounted inside the flow-through pipe body 51. A control connecting rod 53 is mounted at the end of the ball valve main body 52. The control connecting rod 53 is rotatably connected to the flow-through pipe body 51, and the control connecting rod 53 penetrates through the side of the flow-through pipe body 51. A control handle 54 is mounted at the end of the control connecting rod 53. Rotating the control handle 54 provides power for the rotation of the control connecting rod 53, driving the ball valve main body 52 to rotate. A flange 55 is mounted at the top of the flow-through pipe body 51.

[0036] During use, it is toggled manually by the operator's control handle 54. At this time, the control link 53 rotates driven by the control handle 54, providing power for the operation of the ball valve body 52. At this time, the sphere in the ball valve body 52 changes its angle, and the ball groove in the sphere that was originally at the same angle as the hole groove of the flow pipe body 51 rotates, causing the size of the flow aperture of the medium inside the flow pipe body 51 to change, thereby controlling the flow rate of the medium in the flow pipe body 51.

[0037] In this embodiment, two groups of flow pipe bodies 51 are provided, which can independently control the speed of the medium flowing into the conveying chamber 3 and the speed of the medium flowing out. Moreover, a shielding mechanism 6 is also installed inside the flow pipe body 51 installed on the rotating cylinder, which is used to further control the flow rate of the medium in the conveying chamber 3.

[0038] As shown in the appended Figure 4 and Figure 5 figure, it is a schematic structural diagram of the shielding mechanism 6 in this embodiment. The fluoroplastic magnetic pump further includes a shielding mechanism 6. The shielding mechanism 6 includes a shielding ring 61, a connecting bracket 62, a side housing 63, a lead screw 64, a mobile end 65, a first bevel gear 66, a second bevel gear 67, a guide rod 68, and a moving block 69. The side surfaces of the flow pipe body 51 installed at the top opening of the conveying chamber 3 are symmetrically provided with side housings 63. A connecting bracket 62 is slidably installed inside the side housing 63. A shielding ring 61 is installed at the bottom end of the connecting bracket 62. A conveying groove with a radius consistent with the inner diameter of the flow pipe body 51 is opened inside the shielding ring 61. Two groups of side housings 63 are provided. A lead screw 64 is rotatably installed inside one group of side housings 63. A mobile end 65 is threadedly installed outside the lead screw 64. The mobile end 65 is connected to the end of one group of connecting brackets 62. A first bevel gear 66 is installed at the end of the lead screw 64. A second bevel gear 67 is installed outside the control link 53. The second bevel gear 67 is meshed and connected with the first bevel gear 66. A guide rod 68 is installed inside the other group of side housings 63. A moving block 69 is slidably installed outside the guide rod 68. The moving block 69 is connected to the end of the other group of connecting brackets 62.

[0039] During use, by controlling the rotation of the connecting rod 53 as a whole, power is provided for the operation of the second bevel gear 67. The second bevel gear 67 meshes with the first bevel gear 66. At this time, the lead screw 64 rotates as a whole, driving the moving end 65 outside the lead screw 64 to move along the external thread direction of the lead screw 64, adjusting the height of the moving end 65 in the side housing 63. Cooperating with the connecting bracket 62 connected to the end of the moving end 65, the shielding ring 61 moves towards the side close to the stirring impeller 4. In the embodiment, the shielding ring 61 is semi-circular as a whole. When the stirring impeller 4 stirs the medium flowing into the conveying chamber 3, the shielding ring 61 approaches the stirring impeller 4, which will reduce the centrifugal force generated by the stirring impeller 4 stirring the medium, so as to achieve the purpose of controlling the medium flow rate.

[0040] During the movement of the shielding ring 61, the moving block 69 installed at the end of the other set of connecting brackets 62 will stably slide along the length direction of the guide rod 68, realizing the vertical and stable lifting of the shielding ring 61 and ensuring that the shielding ring 61 stably approaches the outside of the stirring impeller 4.

[0041] During actual use, the lengths of the lead screw 64 and the guide rod 68 limit the maximum moving distance of the shielding ring 61, preventing the inner wall of the shielding ring 61 from contacting the stirring impeller 4 and improving the overall safety of the equipment.

[0042] As shown in the appendix Figure 6 This is a schematic structural diagram of the stirring impeller 4 in this embodiment. The stirring impeller 4 includes a transmission rod 41, an impeller main body 42, a pressing cap 43, a threaded end 44, a guide plate 45 and a fixing plate 46. The transmission rod 41 is installed on the magnetic pump main body 2, and the impeller main body 42 is slidably installed outside the transmission rod 41. The threaded end 44 is installed at the top of the transmission rod 41, and the pressing cap 43 is threadedly installed outside the threaded end 44. The guide plates 45 are symmetrically installed on the transmission rod 41, and the impeller main body 42 is provided with sliding grooves for sliding in cooperation with the guide plates 45. The fixing plate 46 is installed on the side of the impeller main body 42, and the fixing plate 46 and the guide plate 45 are jointly threadedly installed with a threaded rod.

[0043] When it is necessary to control the medium flow rate during use, the conveying chamber 3 can be removed from the side of the magnetic pump main body 2, and then the threaded rod installed on the fixing plate 46 is rotated to release the connection between the fixing plate 46 and the guide plate 45. Then, the pressing cap 43 is rotated to turn the pressing cap 43 out of the threaded end 44. At this time, the impeller main body 42 can be slid out of the transmission rod 41, which is convenient for the operator to replace the impeller main body 42 as a whole. Due to the different sizes and structures of the impeller main body 42 itself, the conveying flow rates of the medium are different, which is convenient for the operator to convey the medium at a predetermined flow rate for a long time.

[0044] The guide plate 45 installed on the transmission rod 41 can assist the impeller main body 42 to be replaced subsequently to be quickly sleeved outside the transmission rod 41, realizing the quick positioning of the installation of the impeller main body 42, facilitating the rotation of the threaded rod after the fixing plate 46 and the guide plate 45 are aligned, and realizing the locking of the overall position of the impeller main body 42.

[0045] As shown Figure 7 in the figure, it is a schematic structural diagram of the impeller main body 42 in this embodiment. The impeller main body 42 includes a rear impeller disc 421, a front impeller disc 422 and impeller blades 423. The rear impeller disc 421 is installed outside the transmission rod 41. The front impeller disc 422 is arranged on the side of the rear impeller disc 421. A plurality of groups of impeller blades 423 are equidistantly installed between the rear impeller disc 421 and the front impeller disc 422.

[0046] In use, according to the different sizes of the rear impeller disc 421 and the front impeller disc 422, there are differences in the centrifugal force generated when the impeller main body 42 rotates as a whole. The arrangement of the impeller blades 423 can guide the medium to pass through the holes and grooves on the front impeller disc 422 and flow out along the outer surface of the impeller blades 423. During subsequent use, the shape and quantity of the impeller blades 423 can be adjusted and replaced to realize the adjustment of the flow rate of the medium.

[0047] The above content further elaborates on the present invention in combination with specific embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, which should all be regarded as falling within the protection scope determined by the claims submitted for the present invention.
