Description

Technical Field

[0001] The utility model relates to the field of wedge-shaped flow meters, in particular to an anti-blocking device for wedge-shaped flow meters. Background Art

[0002] The wedge flowmeter is a differential pressure flowmeter that uses the Bernoulli law of energy conversion in a closed pipe, that is, in a stable fluid situation, the flow rate in the pipe is proportional to the square root of the differential pressure. The wedge flowmeter is particularly suitable for measuring the flow of fluids that are difficult to measure with traditional flowmeters, such as fuel oil, wastewater, coal tar, iron ore slurry, oil slurry, crude oil, carbon black, solution, two-phase fluid, etc.

[0003] However, during the operation of the wedge flowmeter, it is inevitable to encounter mixed garbage materials, such as long flocs, iron filings, silt blocks and other garbage, which can easily cause blockage at the wedge block of the measuring tube in the wedge flowmeter. Most of the wedge flowmeters in the existing technical solutions are integrated structures, which makes it extremely inconvenient for the staff to clean the inner cavity of the measuring tube. If the inner cavity of the measuring tube is not cleaned in time, the measurement accuracy of the wedge flowmeter will be affected. Utility Model Content

[0004] The embodiment of the present application provides an anti-blocking device for a wedge flowmeter, thereby solving the technical problem that most wedge flowmeters in the prior art solutions are of an integrated structure, which makes it extremely inconvenient for staff to clean the inner cavity of the measuring tube. If the inner cavity of the measuring tube is not cleaned in time, the measurement accuracy of the wedge flowmeter will be affected.

[0005] The technical solution adopted in the embodiment of the present application is as follows:

[0006] A wedge-shaped flow meter anti-blocking device comprises a measuring tube, a wedge-shaped block arranged on the inner cavity of the measuring tube, an arc-shaped baffle plate for blocking the measuring tube, a fixing piece for fixing the arc-shaped baffle plate, an arc-shaped support plate for abutting against the arc-shaped baffle plate, and a moving assembly for driving the arc-shaped support plate to move; an arc-shaped groove is provided at the bottom end of the measuring tube directly below the wedge-shaped block; the arc-shaped baffle plate is buckled on the arc-shaped groove; the fixing piece is connected to the arc-shaped baffle plate and the measuring tube; the moving assembly is arranged at the bottom end of the measuring tube; and the arc-shaped support plate is arranged on the moving end of the moving assembly.

[0007] A further technical solution is: the moving assembly includes a moving block, a bent support rod arranged on the moving block, a threaded rod for driving the moving block to move, a ball bearing for supporting the threaded rod, and a limiting slide arranged at the bottom end of the measuring tube; the moving block is threadedly connected to the threaded rod, and the moving block slides on the limiting slide; the ball bearings are arranged at both ends of the threaded rod; the two groups of ball bearings are embedded in the limiting slide; the arc support plate is arranged on the bent support rod.

[0008] A further technical solution is: the moving assembly also includes a threaded handle; the threaded handle is arranged at the bottom end of the threaded rod.

[0009] A further technical solution is: the fixing member is a bolt.

[0010] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0011] 1. Due to the use of the measuring tube, wedge block, arc baffle, fixing, arc support plate and moving assembly, when the wedge flow meter is used for a long time and the wedge block position in the inner cavity of the measuring tube is blocked, the staff will disassemble each set of fixings threaded at the bottom end of the measuring tube in turn, and then the moving assembly will work so that the moving end of the moving assembly drives the arc support plate to move downward away from the arc baffle. At this time, the staff can remove the arc baffle engaged with the arc slot at the bottom end of the measuring tube, and then the staff can clean the wedge block position in the inner cavity of the measuring tube. After the wedge block position in the inner cavity of the measuring tube is cleaned, the staff can then make the arc baffle engaged with the arc slot again and fix it through each set of fixings. At this time, the moving end of the moving assembly drives the arc support plate to move close to the arc baffle again, and the arc support plate is made to rest against the arc baffle, and the entire cleaning operation can be completed. The whole process is simple and reliable, which is convenient for the staff to operate.

[0012] 2. Due to the use of the moving block, the bent support rod, the threaded rod, the ball bearing and the limit slideway, the moving block is threadedly connected to the threaded rod and the moving block slides on the limit slideway, so the moving block can slide up and down along the limit slideway by rotating the threaded rod. Since the arc support plate 5 is fixedly connected to the bent support rod and the bent support rod is fixedly connected to the moving block, when the moving block slides up and down along the limit slideway, the arc support plate can be driven to move toward or away from the measuring tube.

[0013] 3. Due to the setting of the threaded handle, the threaded rod can be driven to rotate by rotating the threaded handle, which makes it more convenient for the staff to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The embodiment of the present application provides an anti-blocking device for a wedge flowmeter, thereby solving the technical problem that most wedge flowmeters in the prior art solutions are of an integrated structure, which makes it extremely inconvenient for staff to clean the inner cavity of the measuring tube. If the inner cavity of the measuring tube is not cleaned in time, the measurement accuracy of the wedge flowmeter will be affected.

[0019] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] A wedge-shaped flow meter anti-blocking device, such as Figure 1 and Figure 2 As shown, it includes a measuring tube 1, a wedge block 2 arranged on the inner cavity of the measuring tube 1, an arc-shaped baffle 3 for blocking the measuring tube 1, a fixing member 4 for fixing the arc-shaped baffle 3, an arc-shaped support plate 5 for abutting against the arc-shaped baffle 3, and a moving assembly 6 for driving the arc-shaped support plate 5 to move. An arc-shaped groove 11 is provided at the bottom end of the measuring tube 1, which is located directly below the wedge block 2. The arc-shaped baffle 3 is buckled on the arc-shaped groove 11. The fixing member 4 is connected to the arc-shaped baffle 3 and the measuring tube 1. The moving assembly 6 is arranged at the bottom end of the measuring tube 1. The arc-shaped support plate 5 is arranged on the moving end of the moving assembly 6.

[0022] The wedge block 2 is fixedly connected to the top of the inner cavity of the measuring tube 1. The arc baffle 3 is adapted to the arc slot 11. The arc baffle 3 is detachably buckled on the arc slot 11. The fixing member 4 is preferably a bolt. A plurality of groups of fixing members 4 arranged in a linear array are provided at both ends of the arc baffle 3. Each group of fixing members 4 passes through the arc baffle 3 and is threadedly connected to the measuring tube 1. The moving component 6 is fixedly connected to the bottom end of the measuring tube 1. The arc support plate 5 is fixedly connected to the moving end of the moving component 6.

[0023] Due to the arrangement of the measuring tube 1, the wedge block 2, the arc-shaped baffle 3, the fixing part 4, the arc-shaped support plate 5 and the moving assembly 6, when the wedge-shaped flowmeter is used for a long time and the wedge block 2 in the inner cavity of the measuring tube 1 is clogged, the staff will disassemble each group of fixing parts 4 threadedly connected to the bottom end of the measuring tube 1 in turn, and then work the moving assembly 6 so that the moving end of the moving assembly 6 drives the arc-shaped support plate 5 to move downward away from the arc-shaped baffle 3. At this time, the staff can remove the arc-shaped baffle 3 engaged on the arc-shaped groove 11 at the bottom end of the measuring tube 1, and then the staff can clean the position of the wedge block 2 in the inner cavity of the measuring tube 1. When the wedge block 2 in the inner cavity of the measuring tube 1 is cleaned, the staff can then snap the arc baffle 3 onto the arc slot 11 again and fix it through each set of fixing parts 4. At this time, the moving end of the moving component 6 drives the arc support plate 5 to move close to the arc baffle 3 and make the arc support plate 5 rest against the arc baffle 3, and the entire cleaning operation can be completed. The whole process is simple and reliable, which is convenient for the staff to operate.

[0024] like Figure 3 As shown, the moving assembly 6 includes a moving block 61, a bent support rod 62 arranged on the moving block 61, a threaded rod 63 for driving the moving block 61 to move, a ball bearing 64 for supporting the threaded rod 63, and a limiting slide 65 arranged at the bottom end of the measuring tube 1. The moving block 61 is threadedly connected to the threaded rod 63, and the moving block 61 slides on the limiting slide 65. Ball bearings 64 are arranged at both ends of the threaded rod 63. Two sets of ball bearings 64 are embedded in the limiting slide 65. The arc support plate 5 is arranged on the bent support rod 62.

[0025] The bent support rod 62 is fixedly connected to the moving block 61. The limit slideway 65 is fixedly connected to the bottom end of the measuring tube 1. Ball bearings 64 are provided at both ends of the threaded rod 63, and the two ends of the threaded rod 63 are respectively fixedly connected to the inner rings of two sets of ball bearings 64. The two sets of ball bearings 64 are fixedly embedded in the upper and lower ends of the limit slideway 65. The arc support plate 5 is fixedly connected to the bent support rod 62.

[0026] Due to the arrangement of the moving block 61, the bent support rod 62, the threaded rod 63, the ball bearing 64 and the limiting slideway 65, the moving block 61 is threadedly connected to the threaded rod 63, and the moving block 61 slides on the limiting slideway 65, so by rotating the threaded rod 63, the moving block 61 can slide up and down along the limiting slideway 65. Since the arc support plate 5 is fixedly connected to the bent support rod 62, and the bent support rod 62 is fixedly connected to the moving block 61, when the moving block 61 slides up and down along the limiting slideway 65, the arc support plate 5 can be driven to move toward or away from the measuring tube 1.

[0027] like Figure 3 As shown, the moving assembly 6 also includes a threaded handle 66. The threaded handle 66 is arranged at the bottom end of the threaded rod 63.

[0028] The threaded handle 66 is fixedly connected to the bottom end of the threaded rod 63 .

[0029] Due to the provision of the threaded handle 66, the threaded rod 63 can be driven to rotate together by rotating the threaded handle 66, thereby making it more convenient for the staff to operate.
