Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of detection equipment, in particular to a concentrated acid detector. Background Technique
[0002] The concentrated acid detector is mainly used for detecting the concentration and temperature of high-temperature gas-containing concentrated sulfuric acid. Its main component is a sensor. The sensor calculates the corresponding concentration according to the change of the concentration-conductivity of the flowing medium to realize the concentration detection of the medium. Since the air contained in the medium will cause the conductivity of the medium to increase, resulting in a higher detected data, a gas-liquid separator is provided upstream of the sensor in the detector to separate and remove the air in the medium to improve the accuracy of the concentration detection.
[0003] During the use of the concentrated acid detector, as the most important component, the sensor needs to be disassembled and assembled regularly for inspection, cleaning, calibration and other maintenance operations to ensure the accuracy of the medium concentration detection. In the existing concentrated acid detectors, the sensor is generally fixedly installed on the conveying pipeline through the flange on its pipeline and the flange on the conveying pipeline by tightening the bolt pair, making the operation of disassembling and assembling the sensor not convenient enough. Moreover, when tightening the bolt pair, due to human operation errors, there will be a large difference in the torque between multiple bolt pairs, resulting in liquid leakage.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] The following will combine the attached drawings in the embodiments of the present utility model Figures 1-4 , and clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.
[0022] As shown in the figure, a concentrated acid detector includes a housing 1. Inside the housing 1, a primary separator 2, a secondary separator 3 and a sensor 4 are provided. A feed pipe 5 is connected to the feed inlet of the primary separator 2, and the discharge outlet of the primary separator 2 is connected to the feed inlet of the secondary separator 3. A discharge pipe 6 is connected to the discharge outlet of the secondary separator 3. A detection pipe 7 is connected to the discharge pipe 6. The sensor 4 is arranged on a connecting pipe 9. Both ends of the connecting pipe 9 are connected to the detection pipe 7 through a connecting assembly 10. The connecting assembly 10 includes a first connecting convex ring 101, a second connecting convex ring 102, a first half hoop 103 and a second half hoop 104. The first connecting convex ring 101 and the second connecting convex ring 102 are respectively fixedly connected to the ends of the connecting pipe 9 and the detection pipe 7. The end of the first half hoop 103 is hinged to the end of the second half hoop 104. A clamping block 105 is formed at the other end of the first half hoop 103. A clamping rod 106 is hinged to the other end of the second half hoop 104. A clamping groove 1051 matching the clamping rod 106 is formed on the clamping block 105. The clamping rod 106 forms a limiting flange 1061. After the first connecting convex ring 101 is butted against the second convex ring, the first half hoop 103 and the second half hoop 104 are sleeved outside the first connecting convex ring 101 and the second connecting convex ring 102. The clamping rod 106 swings towards the clamping block 105, so that the clamping rod 106 is clamped into the clamping groove 1051, and the limiting flange 1061 abuts tightly against the side surface of the clamping block 105.
[0023] In the above structure, the concentrated sulfuric acid to be detected enters the primary separator 2 through the feed pipe 5 for the first gas-liquid separation, and the concentrated sulfuric acid after the first gas-liquid separation enters the secondary separator 3 for the second gas-liquid separation. After the two separations, the concentrated sulfuric acid enters the discharge pipe 6, and part of the concentrated sulfuric acid is diverted to the detection tube 7. When the concentrated sulfuric acid in the detection tube 7 flows through the connecting pipe 9, the sensor 4 detects the concentration of the concentrated sulfuric acid to obtain the concentration data of the concentrated sulfuric acid. After the detected concentrated sulfuric acid flows through the detection tube 7, it is merged into the discharge pipe 6 to realize discharge. Accurate detection data of the concentration of concentrated sulfuric acid is obtained by the above method. Among them, the primary separator 2 and the secondary separator 3 are gas-liquid separators in the prior art, which are mainly detected by the orifice plate and The wire mesh realizes gas-liquid separation, and its specific structure is not described in detail here. The structure of the sensor 4 and the way it is arranged on the connecting pipe 9 are both existing technologies and are not described in detail here. The connection between the connecting pipe 9 and the detection tube 7 is realized by the connecting component 10, and then the structure of the installation of the sensor 4 on the detection tube 7 is realized. The specific operations during disassembly and assembly are as follows: when disassembling the connecting pipe 9 and removing the sensor 4 for cleaning and maintenance, the clamping rod 106 is bendable to swing it in the direction away from the clamping block 105 so that the clamping rod 106 is disengaged from the clamping groove 1051. At this time, the first half hoop 103 can be relative to the second half hoop 104 and swing away from the first connecting convex ring 101 and the second connecting convex ring 102 that cooperate with the second half hoop 104 to tightly hold the first connecting convex ring 101 and the second connecting convex ring 102 Position, then push the first connecting protrusion 101 out of the second half hoop 104, so as to realize the separation of the connecting tube 9 and the detection tube 7, realize the disassembly of the sensor 4, install the connecting tube 9 and the sensor 4 on the detection tube 7, align the first connecting protrusion 101 with the second connecting protrusion 102 and press the sealing gasket 14 between the first connecting protrusion 101 and the second connecting protrusion 102, then put the second half hoop 104 on the first connecting protrusion 101 and the second connecting protrusion 102 so that the first connecting protrusion 101 and the second connecting protrusion 102 are stuck in the second half hoop 104, then swing the first half hoop 103 toward the second half hoop 104 to put the second half hoop 104 on the first connecting protrusion 101 and the second connecting protrusion 1 02, and the first connecting convex ring 101 and the second connecting convex ring are clamped into the first half hoop 103, and then the clamping rod 106 is swung toward the clamping block 105. During the swinging of the clamping block 105, the limiting flange 1061 slides on the guiding inclined surface on the end angle of the clamping block 105 as the clamping rod 106 swings, and gradually tightens the first half hoop 103 and the second half hoop 104. When the clamping rod 106 is clamped into the clamping groove 1051 and the limiting flange 1061 is tightly against the side of the clamping block 105, the first half hoop 103 and the second half hoop 104 cooperate to clamp the first connecting convex ring 101 and the second connecting convex ring 102, so that the first connecting convex ring 101 and the second connecting convex ring 102 are kept aligned and the sealing gasket 14 is pressed.The first half hoop 103 and the second half hoop 104 are stably held in a state of tightly clamping the first connecting convex ring 101 and the second connecting convex ring 102 through the cooperation of the limiting flange 1061 and the clamping block 105, so as to realize the connection between the end of the connecting pipe 9 and the detection pipe 7, and thus realize the installation of the sensor 4 on the detection pipe 7. The structure for disassembling and assembling the sensor 4 in the above manner makes the disassembly and assembly of the sensor 4 very convenient and fast, facilitating daily maintenance operations such as inspection, cleaning, and calibration of the sensor 4 during the daily use of the concentrated acid detector. Moreover, the first connecting convex ring 101 and the second connecting convex ring 102 are aligned and connected by the clamping of the first half hoop 103 and the second half hoop 104, with uniform circumferential force, ensuring the sealing performance after the connection of the first connecting convex ring 101 and the second connecting convex ring 102, and preventing liquid leakage during the operation of the concentrated acid detector.
[0024] In addition, a limiting protrusion 1062 is formed on the surface of the limiting flange 1061 facing the clamping block 105, and a limiting groove 1052 matching the limiting protrusion 1062 is formed on the side surface of the clamping block 105. The limiting protrusion 1062 is inserted into the limiting groove 1052. The cooperation of the limiting protrusion 1062 and the limiting groove 1052 limits the swing of the limiting flange 1061 along with the clamping rod 106, so that the limiting flange 1061 is more stably held in a position tightly against the clamping block 105, and the first half hoop 103 and the second half hoop 104 more stably clamp the first connecting convex ring 101 and the second connecting convex ring 102, strengthening the stability of the connection between the connecting pipe 9 and the detection pipe 7, and thus strengthening the stability of the sensor 4 after installation.
[0025] In addition, on the inner walls of the upper horizontal parts of the first half hoop 103 and the second half hoop 104, a first limiting convex strip 107 in an arc shape with the hinge axis of the first half hoop 103 and the second half hoop 104 as the center is formed respectively. On the inner walls of the lower horizontal parts of the first half hoop 103 and the second half hoop 104, a second limiting convex strip 108 in an arc shape with the hinge axis of the first half hoop 103 and the second half hoop 104 as the center is formed respectively. On the end faces of the first connecting convex ring 101 and the second connecting convex ring 102, arc-shaped second limiting ring grooves 1011 and first limiting ring grooves 1021 matching the second limiting convex strip 108 and the first limiting convex strip 107 are respectively formed. The first limiting convex strip 107 and the second limiting convex strip 108 are respectively held in the first limiting ring groove 1021 and the second limiting ring groove 1011. When the second half hoop 104 is sleeved on the first connecting convex ring 101 and the second connecting convex ring 102, the first limiting convex strip 107 and the second limiting convex strip 108 on the inner wall of the second half hoop 104 slide into the first limiting ring groove 1021 and the second limiting ring groove 1011 along with the rotation of the second half hoop 104. Similarly, the first limiting convex strip 107 and the second limiting convex strip 108 on the inner wall of the first half hoop 103 slide into the first limiting ring groove 1021 and the second limiting ring groove 1011 along with the swing of the first half hoop 103 towards the second half hoop 104. Through the cooperation of the first limiting convex strip 107 and the first limiting ring groove 1021, the rotation of the second connecting convex ring 102 relative to the first half hoop 103 and the second half hoop 104 is limited. Through the cooperation of the second limiting convex strip 108 and the second limiting ring groove 1011, the rotation of the first connecting convex ring 101 relative to the first half hoop 103 and the second half hoop 104 is limited, and the rotation of the first connecting convex ring 101 relative to the second connecting convex ring 102 is limited, so that the first connecting convex ring 101 and the second connecting convex ring 102 are more stably kept aligned and connected, thereby strengthening the stability after the connection pipe 9 and the detection pipe 7 are connected, and further strengthening the stability after the sensor 4 is installed.
[0026] In addition, a hook-shaped handle 1063 is formed at the end of the clamping rod 106, and it is convenient to swing the clamping rod 106 by the handle 1063 for the disassembly and assembly operation of the sensor 4.
[0027] In addition, an air outlet pipe 8 is connected to the air outlets of the primary separator 2 and the secondary separator 3, and a balance pipe 11 with the other end communicated with the air outlet pipe 8 is connected to the detection pipe 7. Through the action of the balance pipe 11, the air pressure in the detection pipe 7 is kept balanced with the air pressure in the air outlet pipe 8, avoiding the generation of negative pressure in the detection pipe 7, ensuring the smoothness of the concentrated sulfuric acid flowing in the detection pipe 7, and thus ensuring the stability when the sensor 4 detects the concentration of the concentrated sulfuric acid.
[0028] In addition, the detection tube 7 is in an inverted U shape, and the connecting tube 9 is connected to the vertical portion of the detection tube 7 close to the secondary separator 3, so that the connecting tube 9 is erected. When the concentrated sulfuric acid flows through the connecting tube 9 and is detected by the sensor 4, the residual amount of the concentrated sulfuric acid in the connecting tube 9 is reduced, and the erosion of the sensor 4 by the concentrated sulfuric acid during the non-detection time is reduced, thereby prolonging the service life of the sensor 4.
[0029] In addition, an air outlet valve 12 is provided on the air outlet pipe 8, and a discharge valve 13 is provided on the discharge pipe 6 between the two vertical portions of the detection tube 7. The air outlet valve 12 is used to adjust the air outlet volume of the air outlet pipe 8, and the discharge valve 13 is used to adjust the flow rate of the concentrated sulfuric acid during discharging, so as to make the concentrated sulfuric acid flow smoothly from the feed pipe 5 into the concentrated sulfuric acid detector, thereby ensuring the stability during detection.
[0030] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
