Description

Technical Field

[0001] The utility model relates to the technical field of probe fixing and installation, in particular to a fixing device for a density meter detection probe. Background Art

[0002] The solid-liquid ratio is an important process indicator in the vacuum salt-making industry, and the evaporation and salt discharge processes have relatively strict requirements for this indicator. At present, there are two ways to measure the solid-liquid ratio: one is manual measurement, which is measured once an hour, with high labor intensity, high risk, certain subjectivity in the measurement results, and inability to measure continuously. The second method uses a pressure transmitter to detect the pressure in the upper and lower sections, and uses the pressure difference to calculate the density of the salt slurry solution, and then calculates the solid-liquid ratio of the salt slurry. However, this method is not intuitive, and the segmented installation is not simple. The detection is also greatly affected by the feeding pressure and liquid level fluctuations in the tank body, and the detection data cannot be stable, which affects the calculation. The accuracy of the solid-liquid ratio is poor, especially when the feeding and discharge liquid level fluctuates greatly, the data is distorted.

[0003] Traditional density meters require liquid to flow through the measuring cylinder, but in vacuum salt production, the characteristics of high-temperature salt slurry are very easy to crystallize in the cylinder, causing the density meter to fail to work properly. Therefore, this method is difficult to measure continuously online in production. However, the current Class 5 radio wave density meter is harmless to the environment and personnel. It can monitor the density of the liquid without direct contact with the salt slurry, overcoming the difficulty of easy crystallization of salt and the problem of large interference from liquid level fluctuations; however, in actual use, the density meter detection probe is usually fixed to the outer wall of the fluid pipeline by glue or cable ties, which is inconvenient, time-consuming and labor-intensive, and easily causes damage to the density meter detection probe.

The opposite sides of the top plate 23 are movably connected to the limit seat 21 via the connecting piece 22. The clamping piece 24 is connected to the top plate 23 and is passed through the limit space 210. When the density meter detection probe is arranged in the limit space 210 and fits with the fluid pipeline via the through hole 111, the top plate 23 is driven to approach the limit seat 21 through the connecting piece 22, so that the clamping piece 24 is in contact with the density meter detection probe.

[0025] In this specific embodiment, please refer to Figure 1 The mounting frame 1 also includes two fixing members 12 respectively arranged on opposite sides of the base plate 11, and the fixing members 12 include two detachably connected connecting blocks, and a circular space for the fluid pipeline to pass through is formed between the two connecting blocks, wherein one of the connecting blocks is fixedly connected to the base plate 11.

[0026] It should be noted that the two connecting blocks are both semi-circular in shape, and flanges are provided on both sides of the two connecting blocks, and connecting holes are opened on the flanges. When a circular space is formed between the two connecting blocks for the fluid pipeline to pass through, the centers of the two connecting holes on the two adjacent flanges coincide with each other, and the two connecting blocks can be fixed by passing bolts through the two connecting holes and screwing them into nuts.

[0027] In this specific embodiment, please refer to Figure 3The limit seat 21 includes a horizontal plate 211 and vertical plates 212 fixed on opposite sides of the horizontal plate 211.

[0033] It should be noted that when the second magnetic block 2414 and the first magnetic block 2413 are close to each other, a mutually repelling force is formed between the second magnetic block 2414 and the first magnetic block 2413, further ensuring that the pressing block 242 can press the density meter detection probe. The pressing block 242 is an elastic rubber pressing block.

[0034] On the basis of the above solution, in order to facilitate pulling the top plate 23 away from the horizontal plate 211 , specifically, a handle 231 is fixedly provided on the top plate 23 for facilitating pulling the top plate 23 away from the horizontal plate 211 .

[0035] In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the utility model is described in detail: by pulling the top plate 23 and the cross plate 211 away from each other, adjusting the depth of the clamping member 24 extending into the limit space 210, placing the density meter detection probe in the limit space 210, and fitting the density meter detection probe with the fluid pipeline via the through hole 111, after loosening the top plate 23, the pressure block 242 can press the density meter detection probe under the action of the elastic restoring force of the spring 223.
