Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of emulsification equipment, in particular to an emulsification pump and an emulsification pump fault monitoring method. BACKGROUND

[0002] The emulsification pump is an online dispersion device that can realize mixing, homogenization, dispersion, pulverization and emulsification through the precise combination of a stator and a rotor rotating at high speed, and can continuously process materials and eliminate quality differences between batches when installed on a pipeline. The basic structure of the emulsification pump is composed of a pump cavity and a pair of stator and rotor. Electric energy is the source of power of the emulsification pump. The emulsification pump mainly relies on electric power to convert electric energy into the power of high-speed rotation of the rotor. The product to be mixed is pulverized and emulsified under the strong shear force generated by the high-speed rotation of the rotor, and then discharged from the bottom of the emulsification pump.

[0003] At present, most of the emulsification pump devices can well complete the pulverization, homogenization and emulsification of the mixed substances. However, after long-term use of the device, the device may have many faults. If the emulsification efficiency of the emulsification pump decreases, the emulsification efficiency of the device may be reduced, and the pulverization efficiency of the mixed substances may be reduced, thereby producing some particles that have not been pulverized. The current emulsification pump cannot know in time that the emulsification pump has failed, so that the concentration of the liquid after emulsification is not required by the production line, resulting in frequent rework, increasing the operation difficulty and bringing inconvenience to production.

[0036] In order to solve the problem that the emulsification pump in the prior art cannot be known in time when a fault occurs, the present application provides an emulsification pump and an emulsification pump fault monitoring method.

[0037] As Figures 1 to 5As shown, the emulsifying pump comprises an emulsifying pump body 10 and a fault monitoring device, the fault monitoring device comprises a feeding pipe 20, a filtering assembly 30, a discharging pipe 40, a blowing assembly 50 and a fault monitoring system, one end of the feeding pipe 20 is connected with the emulsifying pump body 10; the filtering assembly 30 has a containing cavity, an impurity collecting cavity 31, a first filter plate 32 and a sealing plate, the first filter plate 32 is arranged in the containing cavity and separates the containing cavity into a filtering cavity 33 above the first filter plate 32 and a discharging cavity below the first filter plate 32, the sealing plate is arranged at the communication between the impurity collecting cavity 31 and the filtering cavity 33 in an openable and closable manner; at least a part of the discharging pipe 40 is communicated with the discharging cavity, so that the material filtered by the first filter plate 32 flows into the discharging pipe 40, and the filtered impurities are left on the first filter plate 32; the blowing assembly 50 is located on the opposite sides of the containing cavity with the impurity collecting cavity 31, the blowing assembly 50 is communicated with the containing cavity, blows the sealing plate from the closed position to the open position, and blows air into the filtering cavity 33 to blow the filtered impurities on the first filter plate 32 into the impurity collecting cavity 31; at least a part of the fault monitoring system is arranged in the impurity collecting cavity 31 to detect the total amount of impurities generated by the emulsifying pump and send an alarm when the total amount of impurities exceeds the standard.

[0038] By arranging the emulsifying pump body 10, the material to be emulsified is emulsified in the emulsifying pump body 10, and the body fluid after emulsification flows into the fault monitoring device, the fault monitoring device can monitor the operation of the emulsifying pump body 10, so as to find the fault of the emulsifying pump in time and reduce the rework rate.

[0040] Embodiment one

[0041] As Figure 1As shown, the filtering assembly 30 comprises a filtering box 35 and a collecting box 36. The filtering box 35 has a containing cavity, and the first filtering plate 32 is arranged in the filtering box 35. The filtering box 35 has a feeding port 351 communicating with the filtering cavity 33, a first discharging port communicating with a discharging cavity, an air inlet port 352 and an air outlet port communicating with the filtering cavity 33. The feeding pipe 20 is connected with the feeding port 351, and at least a part of the discharging pipe 40 is connected with the first discharging port. The air inlet port 352 and the air outlet port are respectively arranged on the opposite side walls of the filtering box 35, and the blowing assembly 50 is connected with the air inlet port 352. The collecting box 36 has a foreign matter collecting cavity 31, and the collecting box 36 is connected with the side wall of the filtering box 35 having the air outlet port. The collecting box 36 has a communicating port communicating with the air outlet port, and a sealing plate is arranged at the communicating port. The air inlet port 352 and the air outlet port are oppositely arranged, so that the air blown by the blowing assembly 50 can blow the foreign matter into the foreign matter collecting cavity 31.

[0042] The side of the collecting box 36 away from the filtering box has a ventilation hole 361, and the inner wall surface of the ventilation hole 361 is fixedly connected with a blocking net 362, so as to facilitate the air flow in the collecting box 36.

[0043] In Figure 4 In the specific embodiment shown, the lower end of the foreign matter collecting cavity 31 is provided with a flow guide plate 130 around the periphery, so as to guide the foreign matter entering the foreign matter collecting cavity 31. The two sides of the collecting box 36 are fixedly connected with support frames 358, and the bottom ends of the support frames 358 are connected with the connecting bottom plate 120. The support frames 358 support the collecting box 36.

[0044] Optionally, the collecting box 36 is detachably connected with the filtering box 35, so as to detach the collecting box 36 to clean the foreign matter in the foreign matter collecting cavity 31, thereby ensuring the accuracy of detection.

[0045] Of course, the collecting box 36 can also have an openable and closable door structure, so as to clean the foreign matter in the foreign matter collecting cavity 31.

[0046] As Figure 1 shown, the blowing assembly 50 comprises an air pump 51 and a blowing pipe 52. The air pump 51 is arranged between the filtering assembly 30 and the emulsifying pump body 10. One end of the blowing pipe 52 is connected with the air pump 51, and the other end of the blowing pipe 52 is connected with the air inlet port 352, so that the air pump 51 sends air into the filtering cavity 33. The blowing pipe 52 is used to communicate the air pump 51 with the filtering cavity 33, so that the air blown by the air pump 51 is blown into the filtering cavity 33, and the foreign matter on the first filtering plate 32 is blown into the foreign matter collecting cavity 31.

[0047] As Figure 2As shown, the filter assembly 30 further comprises at least one second filter plate 37, which is arranged in the filter cavity 33 and is arranged above the first filter plate 32 in a vertical plane. The liquid is filtered by the second filter plate 37 before the first filter plate 32, so as to facilitate the flow of the liquid. The second filter plate 37 is vertical to the first filter plate 32, and the impurities filtered by the second filter plate 37 will fall onto the first filter plate 32 under the action of gravity. When the blowing assembly 50 is working, all the impurities can be blown into the impurity collecting cavity 31, thereby ensuring the accuracy of detection.

[0048] In Figure 1 In the specific embodiment shown, the filter box 35 further has a second discharge port, which is located on the opposite side of the filter box 35 from the first discharge port 351. The second filter plate 37 is located between the first discharge port 351 and the second discharge port, and the second filter plate 37 is arranged at an angle with respect to the line connecting the first discharge port 351 and the second discharge port. In this way, part of the liquid filtered by the second filter plate 37 can flow out of the filter cavity 33 through the second discharge port. The provision of the second discharge port allows the liquid to flow out of the filter cavity 33 through two different discharge ports. The first discharge port 351 and the second discharge port are located on opposite sides of the second filter plate 37, respectively. When the liquid flows into the filter box 35 through the feeding pipe 20, part of the liquid can be filtered by the second filter plate 37 and then directly flow out through the second discharge port due to the flow rate of the liquid. The other part of the liquid and the impurities filtered by the second filter plate 37 flow downward under the action of gravity and then flow onto the first filter plate 32. The liquid is filtered by the first filter plate 32, and the impurities filtered by the first filter plate 32 and the second filter plate 37 are blown into the impurity collecting cavity 31 by the blowing assembly 50, thereby ensuring the accuracy of detection and facilitating the timely detection of whether the emulsifying pump is malfunctioning.

[0049] The emulsified liquid has poor flowability due to its viscosity. The provision of the first discharge port and the second discharge port facilitates the rapid flow of the liquid and avoids the accumulation of the liquid in the containing cavity.

[0050] As Figure 1As shown, the discharge pipe 40 includes a first discharge pipe section 41 and a second discharge pipe section 42, the first discharge pipe section 41 is located below the filter assembly 30, and the feed end of the first discharge pipe section 41 is connected with the first discharge port; the feed end of the second discharge pipe section 42 is connected with the second discharge port, and the discharge end of the first discharge pipe section 41 is connected with the second discharge pipe section 42. In this way, the liquid flowing in through the first discharge port and the second discharge port can all flow out through the discharge pipe 40, so as to facilitate the collection of the liquid flowing out of the emulsifying pump. That is, the liquid flowing out through the second discharge port flows out through the second discharge pipe section 42, and the liquid flowing out through the first discharge port flows into the second discharge pipe section 42 through the first discharge pipe section 41, and then flows out through the second discharge pipe section 42.

[0051] As shown in Figure 1 The pipe diameter of the first discharge pipe section 41 is smaller than that of the second discharge pipe section 42. Since the liquid flowing into the containing cavity through the feed pipe 20 will flow forward under the action of inertia, most of the liquid needs to be discharged through the second discharge pipe section 42, and a small part of the liquid is discharged through the first discharge pipe section 41. By setting the pipe diameter of the first discharge pipe section 41 to be smaller than that of the second discharge pipe section 42, the liquid can be quickly discharged to avoid excessive pressure at the containing cavity and the feed pipe.

[0052] As shown in Figure 1 The filter box 35 includes a filter frame 353, an interception frame 355, a flow guide frame 357, and a support frame 358. The filter box 35 is assembled by the filter frame 353, the interception frame 355, the flow guide frame 357, and the support frame 358, so as to facilitate the installation of the structure placed in the filter box 35.

[0053] The filter frame 353 has a feed port 351, a second discharge port, and a communication slot 354, and the second filter plate 37 is arranged in the filter frame 353. The communication slot 354 not only facilitates the flow of liquid from the filter frame 353 into the interception frame 355, but also facilitates the disassembly and assembly of the second filter plate 37.

[0054] Optionally, the second filter plate 37 is a plurality of second filter plates 37, and the plurality of second filter plates 37 are arranged in the extension direction of the line connecting the feed port 351 and the second discharge port.

[0055] The interception frame 355 is connected below the filtering frame 353, the interception frame 355 has an upper end opening 356 connected with the filtering frame 353 and matched with the outer wall surface of the filtering frame 353, so that the communication slot 354 is communicated with the upper end opening 356, and the first filter plate 32 is arranged at the lower end opening, the side wall of the interception frame 355 has an air inlet 352 and an air outlet, and the filtering frame 353, the interception frame 355 and the first filter plate 32 surround the filtering cavity 33. In this way, the installation of the first filter plate 32 is facilitated, the connection between the filtering frame 353 and the interception frame 355 is ensured to be tight, liquid leakage is avoided, and the liquid filtered by the first filter plate 32 flows into the flow guide frame 357.

[0056] The flow guide frame 357 has a discharge cavity, a flow guide opening communicated with the discharge cavity and a first discharge opening, the flow guide frame 357 is connected below the interception frame 355, the flow guide opening is communicated with the lower end opening, and the support frame 358 is connected with the flow guide frame 357 to support the flow guide frame 357. The cross-sectional area of the flow guide frame 357 gradually decreases from the flow guide opening to the first discharge opening, which is beneficial to guide the liquid into the first discharge pipe section 41. The support frame 358 is connected with the connecting bottom plate 120, so that the flow guide frame 357 is arranged in a spaced manner with the connecting bottom plate 120, the first discharge pipe section 41 is installed below the flow guide frame 357, and the space is utilized reasonably.

[0068] In this embodiment, the emulsion pump fault monitoring method is used for the emulsion pump described above, and the emulsion pump fault monitoring method comprises: starting the emulsion pump, and the emulsion pump body 10 of the emulsion pump performing crushing and emulsifying operation on the material to be mixed; after the emulsifying operation is completed, opening the feed pipe 20 of the emulsion pump, and the emulsified liquid flowing out through the feed pipe 20, the filter assembly 30 and the discharge pipe 40 of the emulsion pump in sequence; after all the emulsified liquid flows out of the discharge pipe 40, starting the blowing assembly 50 of the emulsion pump to blow the impurities filtered on the first filter plate 32 of the emulsion pump into the impurity collection cavity 31 of the filter assembly 30, the weight sensor 70 of the emulsion pump weighing the impurities to form a detected weight, and sending the detected weight to the center control module 60 of the emulsion pump, and when the detected weight is greater than a preset weight, the center control module 60 controls the alarm unit 80 of the emulsion pump to work. Such arrangement can timely monitor the working state of the emulsion pump, and after the emulsion pump body 10 completes emulsification once, it can be quickly known whether there is impurity in the liquid after the liquid flows out, so as to ensure the consistency of the liquid. When there is too much impurity in the liquid, the alarm unit 80 issues an alarm to remind the maintenance personnel to maintain as soon as possible, thereby reducing the rework rate.

[0069] Specifically, the alarm unit 80 includes a siren and a buzzer.

[0070] In the embodiment, during the process that the emulsifying pump body 10 of the emulsifying pump performs the crushing and emulsifying operation on the material to be mixed after the emulsifying pump is started, the temperature sensor 90 of the emulsifying pump detects the temperature of the emulsifying pump body 10 to form a detection temperature, and sends the detection temperature to the central control module 60. When the detection temperature is greater than the preset temperature, the central control module 60 controls the alarm unit 80 to work. This setting is conducive to timely monitoring the working temperature of the emulsifying pump body 10, ensuring the stable working of the emulsifying pump body 10, and also controlling the emulsifying temperature within a reasonable range, avoiding the influence of high temperature on the performance of the liquid.

[0071] In the embodiment, after the emulsifying operation is completed, the feeding pipe 20 of the emulsifying pump is opened, and the emulsified liquid flows out through the feeding pipe 20, the filtering assembly 30 of the emulsifying pump and the discharge pipe 40 of the emulsifying pump in sequence. During the process, the pressure transmitter 100 of the emulsifying pump detects the pressure in the inner cavity of the filtering frame 353 to form a detection pressure, and sends the detection pressure to the central control module 60. When the detection pressure is greater than the preset pressure, the central control module 60 controls the alarm unit 80 to work. This setting is conducive to timely monitoring the pressure in the inner cavity of the filtering frame 353, ensuring the stable working of the emulsifying pump body 10, and avoiding the damage of the emulsifying pump caused by excessively high pressure.

[0072] In the embodiment, after the emulsifying operation is completed, the feeding pipe 20 of the emulsifying pump is opened, and the emulsified liquid flows out through the feeding pipe 20, the filtering assembly 30 of the emulsifying pump and the discharge pipe 40 of the emulsifying pump in sequence. During the process, the liquid level sensor 110 of the emulsifying pump detects the liquid level in the inner cavity of the intercepting frame 355 of the filtering assembly 30 to form a detection liquid level, and sends the detection liquid level to the central control module 60. When the detection liquid level is greater than the preset liquid level, the central control module 60 controls the alarm unit 80 to work. This setting is conducive to timely monitoring the liquid level in the inner cavity of the intercepting frame 355, ensuring the stable working of the emulsifying pump body 10. Since the liquid flow rate decreases when the first filter plate 32 is blocked, the liquid level rises, and the liquid level sensor 110 can timely issue an alarm when the first filter plate 32 is blocked.
