Description

Technical Field

[0001] This utility model relates to the field of drive gear pump technology, specifically an explosion-proof magnetic gear pump. Background Technology

[0002] A magnetic drive pump consists of a pump casing, impeller, inner magnetic rotor, sealing ring, isolation sleeve, reinforcing sleeve, outer magnetic cylinder, support frame, motor, and base. A magnetic drive pump is a device that uses the interaction between a magnet and a magnetically conductive metal body to transmit power and transport liquids or mixtures of liquids. Its working principle is as follows: when the motor drives the outer magnetic rotor to rotate, the magnetic field can penetrate the air gap and non-magnetic materials, driving the inner magnetic rotor connected to the impeller to rotate synchronously, thus realizing the transmission of power and the transport of liquid.

[0003] A search revealed that prior art publication number CN221547283U discloses an explosion-proof magnetically driven gear pump, including a rotating motor. A mounting base is located at the front end of the rotating motor shaft, and a gear pump body is located at the front end of the rotating motor shaft. An inlet is located at the front end of the gear pump body, and an outlet is located at the top of the gear pump body. A filter disc is installed at the front end of the inlet, and a filter assembly for auxiliary liquid filtration is located in the middle section of the filter disc. The filter assembly includes protruding plates symmetrically fixed to the outer edge of the filter disc, and a connecting plate is inserted between the two protruding plates. The filter disc has insertion holes for inserting the filter assembly, and the connecting plate has two symmetrically symmetrical passage cavities. This invention utilizes filter screens for auxiliary liquid filtration installed within the cavities, a positioning component installed at the top of the protruding plates, and a positioning hole at the top of the connecting plate that cooperates with the positioning component for positioning. This minimizes the need to stop the gear pump to replace the filter screen, improving the overall replacement efficiency of the explosion-proof magnetically driven gear pump.

[0004] However, this utility model requires manual replacement for each cleaning, and blockages still occur if it is not replaced, causing a decrease in the liquid flow rate in the pump body. Therefore, an explosion-proof magnetic gear pump is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an explosion-proof magnetic gear pump, which has the advantages of regular automatic cleaning and collection. It solves the problem that manual replacement is required every time the pump is cleaned, and blockages can still occur if the pump is not replaced, resulting in a decrease in the liquid flow rate inside the pump.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof magnetic gear pump, including a gear pump body, a motor fixedly installed on the left side of the gear pump body, a water outlet pipe connected to the upper side of the gear pump body, a water inlet filter device provided on the right side of the gear pump body, and a flow guide device provided on the lower side of the gear pump body.

[0007] The water inlet filtration device includes a first connecting pipe bolted to the right side of the gear pump body, a filter plate inserted into the left side of the first connecting pipe, a bearing seat fixedly connected to the right side of the first connecting pipe, a connecting rod inserted into the left side of the bearing seat, a spring sleeved on the outside of the connecting rod, a sleeve fixedly connected to the left side of the spring, a fan blade fixedly connected to the left side of the sleeve, and a cleaning brush fixedly connected to the left side of the fan blade.

[0008] The flow guiding device includes a second connecting pipe connected to the lower side of the gear pump body, an internal movable plate bolted to the right side of the second connecting pipe, a filter cylinder slidably sleeved inside the second connecting pipe, and a top column fixedly connected to the lower side of the filter cylinder.

[0009] Furthermore, two positioning blocks are fixedly connected inside the first connecting pipe, and the left side of the filter plate is inserted into the positioning block.

[0010] Furthermore, a slider is fixedly connected to the outside of the connecting rod, and a groove matching the slider is provided inside the sleeve.

[0011] Furthermore, the slider is slidably connected within the groove.

[0012] Furthermore, the filter plate is a stainless steel filter plate.

[0013] Furthermore, a through hole is provided inside the lower side of the first connecting pipe, and one end of the second connecting pipe abuts against the lower end of the through hole.

[0014] Furthermore, the right side of the movable plate is rotatably fitted inside the second connecting pipe, and the bottom of the top column abuts against the upper end of the movable plate.

[0015] Furthermore, two columns are fixedly connected inside the right side of the second connecting pipe, and the two columns are vertically fixedly connected to the inner wall surface of the second connecting pipe.

[0016] Compared with the prior art, this utility model provides an explosion-proof magnetic gear pump, which has the following beneficial effects:

[0017] 1. This explosion-proof magnetic gear pump allows liquid to enter the inlet water filtration device. The resulting thrust drives the cleaning brush to contact the surface of the filter plate, which in turn drives the fan blades to rotate. The cleaning brush cleans the impurities filtered from the surface of the filter plate, thus achieving automatic cleaning.

[0018] 2. This explosion-proof magnetic gear pump allows impurities and some liquid to fall naturally into the filter cartridge through the through hole after cleaning. The filter cartridge collects the impurities while separating the liquid, which flows to the left through the second connecting pipe, thus completing the purpose of impurity collection. This solves the problem that manual replacement is required every time the pump is cleaned, and blockages can still occur if the pump is not replaced, resulting in a decrease in the liquid flow rate inside the pump.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please see Figures 1 to 5The explosion-proof magnetic gear pump in this embodiment includes a gear pump body 2, a motor 1 fixedly installed on the left side of the gear pump body 2, a water outlet pipe 3 connected to the upper side of the gear pump body 2, a water inlet filter device 4 provided on the right side of the gear pump body 2, and a flow guide device 5 provided on the lower side of the gear pump body 2. The water inlet filter device 4 includes a first connecting pipe 6 bolted to the right side of the gear pump body 2, a filter plate 13 inserted into the left side of the first connecting pipe 6, a bearing seat 7 fixedly connected to the right side of the first connecting pipe 6, a connecting rod 8 inserted into the left side of the bearing seat 7, a spring 10 sleeved on the outside of the connecting rod 8, a sleeve 9 fixedly connected to the left side of the spring 10, a fan blade 11 fixedly connected to the left side of the sleeve 9, and a cleaning brush 12 fixedly connected to the left side of the fan blade 11. The flow guiding device 5 includes a second connecting pipe 16 connected to the lower side of the gear pump body 2, an internal movable plate 20 bolted to the right side of the second connecting pipe 16, a filter cylinder 19 slidably sleeved inside the second connecting pipe 16, and a top column 18 fixedly connected to the lower side of the filter cylinder 19.

[0028] The first connecting pipe 6 has two fixedly connected positioning blocks 14 inside. The left side of the filter plate 13 is inserted into the positioning block 14. The outer side of the connecting rod 8 is fixedly connected to a slider. The sleeve 9 has a groove inside that matches the slider. The slider slides in the groove. The filter plate 13 is a stainless steel filter plate. The lower side of the first connecting pipe 6 has a through hole 15 inside. One end of the second connecting pipe 16 abuts against the lower end of the through hole 15. The right side of the movable plate 20 is rotatably sleeved inside the second connecting pipe 16. The bottom of the top column 18 abuts against the upper end of the movable plate 20.

[0029] Example 2:

[0030] Please see Figure 1 and Figure 4 Based on Embodiment 1, it includes two columns 17 fixedly connected inside the right side of the second connecting pipe 16, and the two columns 17 are vertically fixedly connected to the inner wall surface of the second connecting pipe 16.

[0031] By adopting the above technical solution, the filter cylinder 19 can effectively provide support and guidance when sliding on the outside of the column 17.

[0032] The working principle of the above embodiments is as follows:

[0033] The left side of the inlet filter device 4 is bolted to the right side of the gear pump body 2. The end of the flow guide device 5 is fixedly connected to the outlet pipe 3 and the bottom of the inlet filter device 4, respectively. Liquid enters the filter plate 13 from the first connecting pipe 6 to filter impurities in the liquid. The thrust generated when the liquid is discharged drives the cleaning brush 12 to abut against the surface of the filter plate 13, and the spring 10 is extended. As the liquid continues to be discharged, it will drive the fan blade 11 and the cleaning brush 12 to rotate, cleaning the impurities filtered by the filter plate 13, making the liquid flow better, and then discharged from the outlet pipe 3. After the liquid is discharged, the impurities cleaned will fall from the through hole 15 into the filter cylinder 19. During this process, the filter cylinder 19 can collect the filtered impurities, and the liquid can also be discharged from the lower side of the filter cylinder 19 to the second connecting pipe 16 and flow to the outlet pipe 3. When cleaning, simply separate the movable plate 20, and after the bottom of the top column 18 is no longer limited, it will fall out from the second connecting pipe 16. Clean the impurities remaining in the filter cylinder 19, and then insert both ends of the filter cylinder 19 into the outside of the column 17 for positioning. Then, fix the movable plate 20 with bolts inside the second connecting pipe 16.

[0034] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
