Description
Technical Field
[0001] This utility model belongs to the field of electromagnetic flow meter technology, specifically an electromagnetic flow meter scale removal device. Background Technology
[0002] An electromagnetic flowmeter is an inductive instrument manufactured based on Faraday's law of electromagnetic induction to measure the volumetric flow rate of conductive media in pipes. The structure of an electromagnetic flowmeter mainly consists of a magnetic circuit system, a measuring conduit, electrodes, a housing, a lining, and a converter.
[0003] After a period of use, scale easily forms inside the measuring tube of an electromagnetic flowmeter, which can affect the measurement of the electromagnetic flowmeter. Currently, the measuring tube is usually cleaned manually, which requires manual brushing, resulting in low cleaning efficiency and excessive labor intensity. Utility Model Content
[0004] To overcome the above-mentioned defects, this utility model provides an electromagnetic flowmeter scale cleaning device, which solves the problem that the existing method of cleaning the measuring tube is usually done manually, which requires manual brushing, resulting in low cleaning efficiency and high labor intensity.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an electromagnetic flowmeter scale removal device, comprising a housing, a liquid storage chamber connected to one side of the housing, a partition connected inside the housing, a fixed plate connected to the housing, a movable plate rotatably connected inside the housing, a gear ring connected to the movable plate, multiple spiral grooves formed on the movable plate, a connecting rod slidably connected within the spiral grooves, and a movable block connected to one end of the connecting rod;
[0006] A micro motor is fixedly installed at the other end of the connecting rod. The output shaft of the micro motor is connected to a rotating rod. One end of the rotating rod is connected to a cleaning roller. The cleaning roller is provided with bristles. A handle is connected to the liquid storage tank. A liquid replacement pipe is connected to one side of the liquid storage tank. A liquid pump is fixedly installed below the liquid storage tank. A delivery pipe is connected to the liquid pump. One end of the delivery pipe is connected to a spray pipe.
[0007] As a further embodiment of this utility model: the fixing plate is provided with multiple limiting grooves, and there are three limiting grooves and three spiral grooves, and the three limiting grooves and spiral grooves are all centrally symmetrically distributed.
[0008] As a further embodiment of this utility model: the rotating rod is rotatably connected to the connecting rod and the movable block through a bearing. The connecting rod is T-shaped with its narrow part set in the spiral groove. The movable block slides in the limiting groove and contacts the groove wall of the limiting groove.
[0009] As a further embodiment of this utility model: the spray pipe is fixedly connected to the center of the fixed plate, and the spray pipe has multiple spray holes facing the cleaning roller.
[0010] As a further embodiment of this utility model: the liquid pump is connected to the inside of the liquid storage tank through a pipeline, and a piston is inserted into the liquid exchange pipe.
[0011] As a further embodiment of this utility model: the movable plate is disposed between the partition and the fixed plate, and the center of the movable plate is rotatably connected to the partition. A working motor is fixedly installed on the partition. The output shaft of the working motor passes through the partition and is connected to a gear. The output shaft of the working motor is rotatably connected to the partition through a bearing. The gear meshes with a gear ring.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This electromagnetic flowmeter scale removal device, through the configuration of gears, gear rings, movable plates, connecting rods, movable blocks, limiting grooves, spiral grooves, cleaning rollers, and brushes, allows operators to start a working motor to drive the gears, which in turn mesh with the gear rings to rotate the movable plates. This causes the spiral grooves to push the connecting rods, which in turn causes the movable blocks to slide within the limiting grooves. This allows for adjustment of the distance between multiple cleaning rollers to accommodate electromagnetic flowmeter measuring tubes of different diameters. The micro motor drives the cleaning rollers to rotate via a rotating rod, and the continuously moving cleaning rollers apply pressure to the wall of the measuring tube, thereby cleaning the scale with the brushes. This reduces labor intensity and improves cleaning efficiency.
[0014] 2. This electromagnetic flowmeter scale removal device, by setting up a storage tank, a pump, a delivery pipe, a spray pipe, and spray holes, allows the operator to start the pump to draw the cleaning solvent from the storage tank through the pipeline during scale removal. The pump then delivers the cleaning solvent into the spray pipe via the delivery pipe, allowing the cleaning solvent to be sprayed directly onto the cleaning roller and the inside of the measuring tube through the spray holes on the spray pipe. This allows the cleaning solvent to react with the scale, making it easier to remove and thus improving cleaning efficiency. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0021] like Figure 1-4 As shown, this utility model provides a technical solution: an electromagnetic flowmeter scale cleaning device, including a housing 1, a liquid storage tank 2 connected to one side of the housing 1, a partition 3 connected inside the housing 1, a fixed plate 4 connected to the housing 1, a movable plate 5 rotatably connected inside the housing 1, the movable plate 5 being disposed between the partition 3 and the fixed plate 4, and the center of the movable plate 5 being rotatably connected to the partition 3, a working motor 22 being fixedly installed on the partition 3, the output shaft of the working motor 22 passing through the partition 3 and connected to a gear 23, and the output shaft of the working motor 22 being rotatably connected to the partition 3 through a bearing, the gear 23 meshing with a gear ring 6, the working motor 22 being able to drive the movable plate 5 to rotate inside the housing 1 through the meshing of the gear 23 and the gear ring 6, thereby causing the spiral groove 7 to push the connecting rod 8 to move the cleaning roller 12, so that the cleaning roller 12 adapts to the wall of the measuring tube to complete the cleaning.
[0022] A toothed ring 6 is connected to the movable plate 5, and multiple spiral grooves 7 are opened on the movable plate 5. Multiple limiting grooves 19 are opened on the fixed plate 4. There are three limiting grooves 19 and three spiral grooves 7, and the three limiting grooves 19 and spiral grooves 7 are centrally symmetrically distributed. When the movable plate 5 rotates, the connecting rod 8 slides in the spiral groove 7, so that the spiral groove 7 can push the connecting rod 8, causing multiple cleaning rollers 12 to move synchronously, completing the distance adjustment between multiple cleaning rollers 12 to adapt to different measuring tube diameters, thus improving applicability.
[0023] A connecting rod 8 is slidably connected within the spiral groove 7. One end of the connecting rod 8 is connected to a movable block 9, and the other end of the connecting rod 8 is fixedly mounted with a micro motor 10. The output shaft of the micro motor 10 is connected to a rotating rod 11. The rotating rod 11 is rotatably connected to the connecting rod 8 and the movable block 9 through a bearing. The connecting rod 8 has a T-shaped design, with its narrow part located within the spiral groove 7. The movable block 9 slides within the limiting groove 19, and the movable block 9 contacts the groove wall of the limiting groove 19. Through the contact between the movable block 9 and the groove wall of the limiting groove 19, the limiting groove 19 can restrict the movable block 9, thereby guiding it and enabling the movable block 9 to move smoothly.
[0024] One end of the rotating rod 11 is connected to a cleaning roller 12, which is equipped with bristles 13. A handle 14 is connected to the liquid storage tank 2, and a liquid replacement pipe 15 is connected to one side of the liquid storage tank 2. A liquid pump 16 is fixedly installed below the liquid storage tank 2, and a delivery pipe 17 is connected to the liquid pump 16. The liquid pump 16 is connected to the inside of the liquid storage tank 2 through the pipe. A piston 21 is inserted into the liquid replacement pipe 15. The cleaning solvent in the liquid storage tank 2 can be delivered to the spray pipe 18 through the liquid pump 16 to complete the rinsing work. The liquid replacement pipe 15 allows the staff to easily complete the liquid replacement work.
[0025] One end of the conveying pipe 17 is connected to a spray pipe 18, which is fixedly connected to the center of the fixing plate 4. The spray pipe 18 has multiple spray holes 20 facing the cleaning roller 12. Through the spray holes 20 facing the cleaning roller 12, the cleaning solvent in the spray pipe 18 can be directly sprayed onto the bristles 13 to complete the wetting, so that the cleaning roller 12 can clean the scale.
[0026] The working principle of this utility model is as follows:
[0027] The operator first inserts the clustered cleaning rollers 12 into the measuring tube of the electromagnetic flowmeter. Then, the operator starts the working motor 22, which drives the gear 23 to rotate. The gear 23 meshes with the gear ring 6, causing the movable plate 5 to rotate. This allows the spiral groove 7 to push the connecting rod 8, which in turn causes the movable block 9 to slide within the limiting groove 19. This adjusts the distance between the multiple cleaning rollers 12 to accommodate electromagnetic flowmeter measuring tubes of different diameters. Meanwhile, the micro motor 10 drives the cleaning rollers 12 to rotate via the rotating rod 11, thus cleaning the scale. The liquid pump 16 draws the cleaning solvent from the storage tank 2 through the pipeline and sends it into the spray pipe 18 through the delivery pipe 17. The cleaning solvent is then sprayed directly onto the cleaning rollers 12 and the inside of the measuring tube through the spray holes 20 on the spray pipe 18, allowing the cleaning solvent to react with the scale and make it easier to remove. At the same time, the operator can move the electromagnetic flowmeter to adjust the angle of the measuring tube to complete the thorough cleaning of the tube wall.
