Description

Technical Field

[0001] This utility model belongs to the field of flow meter technology, specifically relating to a heat insulation structure and a Coriolis mass flow meter. Background Technology

[0002] Mass flow measurement technology is a key area of ​​national scientific and technological development in the field of process control. To achieve high accuracy and high reliability in measuring various media under complex environmental conditions, Coriolis mass flow meters have become a new type of measuring instrument that is the focus of development in this field due to their superior performance.

[0003] When using a Coriolis flowmeter to measure the mass flow rate of a medium, there are two operating conditions that require the medium to be insulated or heated. One is that some media themselves need to be insulated, and the other is that the flow capacity is very weak at room temperature and the medium needs to be heated. Therefore, it is necessary to add an insulation structure to the flowmeter.

[0004] Currently, the existing technology basically uses a pair of thermal insulation jackets installed on both sides of the sensor housing to increase the insulation and heating effect of the sensor housing. However, the spacing between the pair of thermal insulation jackets in the existing insulation structure is basically fixed and cannot be adjusted according to the thickness of different sensor housings. Therefore, the applicability of the existing flow meter insulation structure is poor.

[0005] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide an insulation structure and a Coriolis mass flow meter.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] The purpose of this invention is to provide a thermal insulation structure and a Coriolis mass flow meter, which can solve the problem that the spacing between a pair of thermal insulation jackets in existing thermal insulation structures cannot be adjusted.

[0008] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0009] An insulation structure includes: a first insulation jacket, a second insulation jacket, a suspension assembly, and a clamping device.

[0010] The first and second insulation jackets are respectively provided with liquid inlets and liquid outlets at their upper and lower ends. The suspension assembly is installed on the upper ends of the first and second insulation jackets, and flexibly connects the first and second insulation jackets. The clamping device is installed on both sides and the bottom of the first and second insulation jackets. The clamping device includes: a fixed shaft seat, an L-shaped control component, a connecting component, a length adjustment mechanism, and a hook. The fixed shaft seat is fixed to the first insulation jacket. The L-shaped control component rotates on the fixed shaft seat. A locking head is fixed to the end of the L-shaped control component away from the fixed shaft seat. A locking body adapted to the locking head is fixed on the first insulation jacket. The connecting component rotates at the L-shaped corner of the L-shaped control component. The end of the connecting component away from the L-shaped control component is connected to the hook through the length adjustment mechanism. A groove adapted to the hook is fixed on the second insulation jacket.

[0011] In one embodiment of this utility model, multiple partitions are provided in both the first insulation jacket and the liquid inlet. The partitions separate the first insulation jacket and the liquid inlet into an S-shaped flow channel. By separating the first insulation jacket and the liquid inlet into an S-shaped flow channel through the partitions, the residence time of the heat transfer medium in the first insulation jacket and the liquid inlet is increased, thereby improving the thermal efficiency of the heat transfer medium insulation.

[0012] In one embodiment of this utility model, the suspension assembly includes two pairs of connecting rods and a pair of flexible straps. The two pairs of connecting rods are respectively fixed to the upper ends of the first and second insulation jackets. One end of the pair of flexible straps is rotatably connected to one pair of connecting rods, and the other end passes over the other pair of connecting rods and is attached to the flexible strap. When installing the first and second insulation jackets, the first and second insulation jackets are placed on both sides of the sensor housing. Then, the pair of flexible straps passes over the upper pipe and then passes over the other pair of connecting rods and is attached, thereby suspending the first and second insulation jackets on both sides of the sensor housing.

[0013] In one embodiment of this utility model, the flexible strip is provided with Velcro, and the flexible strip is attached by Velcro.

[0014] In one embodiment of this utility model, the length adjustment mechanism includes: a pair of sliding sleeves, a pair of sliding rods, a pair of threaded heads, and a pair of self-locking nut assemblies. The pair of sliding sleeves are fixed to the end of the connector away from the L-shaped control member and are disposed on the two outer side walls of the connector. The pair of sliding rods slide on the pair of sliding sleeves respectively, and their ends near the hook are fixedly connected to the hook. The pair of threaded heads are fixed to the ends of the pair of sliding rods away from the hook. The pair of self-locking nut assemblies are threadedly connected to the pair of threaded heads.

[0015] In use, adjust the length between the claw and the connector according to the width of the sensor housing. Adjust the length of the slide rod extending from the slide sleeve by rotating the position of the self-locking nut assembly on the threaded head, thereby adjusting the length between the claw and the connector.

[0016] In one embodiment of this utility model, springs are installed on each of the pair of sliding rods between the sliding sleeve and the self-locking nut assembly. The springs provide an elastically deformable space when the hook and connector lock the first and second insulation sleeves together, and elastically lock the first and second insulation sleeves together. Furthermore, after locking, the spring force pulls the hook towards the connector, thereby increasing the locking force between the first and second insulation sleeves.

[0017] In one embodiment of this utility model, the self-locking nut assembly includes a locking body, a nut head, a limiting head, and a locking nut. The locking body is threadedly connected to the threaded head. The nut head and the limiting head are respectively fixed to both ends of the locking body. The locking nut is threadedly connected to the outside of the locking body. By screwing the locking nut from one end of the locking body to the other end, the locking body is locked onto the threaded head. The limiting head serves two purposes: firstly, it limits the locking nut to prevent it from detaching from the locking body; secondly, it presses against one end of the spring. The nut head serves two purposes: firstly, it drives the locking body to rotate; secondly, it restricts the rotation of the locking body when the locking nut is rotated, and also serves to limit the locking nut.

[0018] In one embodiment of this utility model, the locking body and the limiting head are evenly chiseled with multiple tightening notches, and one of the tightening notches penetrates through the nut head. The tightening notch is used to reserve space for the locking body to deform when it is tightened inward.

[0019] In one embodiment of this utility model, the locking body includes a smooth section and a locking section, with the locking section extending outwards from the end furthest from the smooth section. When the locking nut is screwed to the smooth section, the locking body does not tighten inwards; at this time, the nut head can drive the locking body to rotate on the threaded head, adjusting the position of the self-locking nut assembly on the threaded head. When the locking nut is screwed to the locking section, the locking nut tightens the locking section portion of the locking body inwards, thereby locking the self-locking nut assembly onto the threaded head.

[0020] This utility model also discloses a Coriolis mass flow meter, including a heat insulation structure.

[0021] Compared with the prior art, this utility model, by setting an adjustable locking device, can adjust the spacing between a pair of insulation jackets according to the width of different sensor shells, thereby effectively improving the practicality of the insulation structure.

Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0032] like Figures 1 to 6 As shown, an embodiment of the present invention provides a thermal insulation structure comprising: a first thermal insulation jacket 1, a second thermal insulation jacket 101, a suspension assembly 105, and a clamping device 2. The first thermal insulation jacket 1 and the second thermal insulation jacket 101 are respectively provided with an inlet 102 and an outlet 103 at their upper and lower ends. The suspension assembly 105 is installed on the upper ends of the first thermal insulation jacket 1 and the second thermal insulation jacket 101, flexibly connecting them. The clamping device 2 is installed on both sides and the bottom of the first thermal insulation jacket 1 and the second thermal insulation jacket 101. The clamping device 2 includes: a fixed shaft seat 203, an L-shaped control component 202, a connecting component 201, a length adjustment mechanism, and a hook 204. The fixed shaft seat 203 is fixed to the first thermal insulation jacket 1. The L-shaped control component 202 rotates on the fixed shaft seat 203, and a clamping head 211 is fixed to one end of the L-shaped control component 202 away from the fixed shaft seat 203. A clip body 212 adapted to the clip head 211 is fixed on the first insulation jacket 1. The connector 201 rotates at the L-shaped corner of the L-shaped control member 202. The end of the connector 201 away from the L-shaped control member 202 is connected to the hook 204 through a length adjustment mechanism. A groove 205 adapted to the hook 204 is fixed on the second insulation jacket 101.

[0033] In practical use, the first insulation jacket 1 and the second insulation jacket 101 are first placed on both sides of the sensor housing. Then, the first insulation jacket 1 and the second insulation jacket 101 are suspended on both sides of the sensor housing by the suspension assembly 105 passing around the pipe at the top of the sensor housing. Then, according to the width of the sensor housing, the length of the hook 204 extending from the connector 201 is adjusted by the length adjustment mechanism. Then, the L-shaped control member 202 is rotated around the fixed shaft seat 203 as the axis. When the L-shaped control member 202 rotates, it drives the connector 201 to rotate and move. By moving the L-shaped control member 202 and the connector 201, the hook 204 is delivered to the groove 205 and hooked into the groove 205. Then, the L-shaped control member 202 is rotated in the opposite direction and the locking head 211 is locked onto the locking body 212, thereby locking and fixing the remaining three side walls of the first insulation jacket 1 and the second insulation jacket 101, so that the first insulation jacket 1 and the second insulation jacket 101 are tightly attached to both sides of the sensor housing.

[0034] After installation, the inlet 102 and outlet 103 on the first insulation jacket 1 and the second insulation jacket 101 are respectively connected to the heat transfer medium delivery pipeline. The heat transfer medium exchanges heat with the sensor shell in the first insulation jacket 1 and the second insulation jacket 101, thereby keeping the sensor warm or raising its temperature.

[0035] like Figures 1 to 2As shown, multiple layers of partitions 104 are provided in both the first insulation jacket 1 and the liquid inlet 102. The partitions 104 separate the first insulation jacket 1 and the liquid inlet 102 into an S-shaped flow channel. By separating the first insulation jacket 1 and the liquid inlet 102 into an S-shaped flow channel through the partitions 104, the residence time of the heat transfer medium in the first insulation jacket 1 and the liquid inlet 102 is increased, thereby improving the thermal efficiency of the heat transfer medium insulation.

[0036] like Figures 1 to 2 As shown, the suspension assembly 105 includes two pairs of connecting rods 106 and a pair of flexible straps 107. The two pairs of connecting rods 106 are respectively fixed to the upper ends of the first insulation jacket 1 and the second insulation jacket 101. One end of each pair of flexible straps 107 is rotatably connected to one pair of connecting rods 106, and the other end passes over the other pair of connecting rods 106 and is attached to the flexible strap 107. During installation, the first insulation jacket 1 and the second insulation jacket 101 are positioned on both sides of the sensor housing. Then, the pair of flexible straps 107 are passed over the upper pipe, and then passed over and attached to the other pair of connecting rods 106, thereby suspending the first insulation jacket 1 and the second insulation jacket 101 on both sides of the sensor housing. Velcro 108 is provided on the flexible straps 107, and the flexible straps 107 are attached using the Velcro 108.

[0037] like Figures 3 to 4 As shown, the length adjustment mechanism includes: a pair of sliding sleeves 207, a pair of sliding rods 206, a pair of threaded heads 208, and a pair of self-locking nut assemblies 209. The pair of sliding sleeves 207 are fixed to the end of the connector 201 away from the L-shaped control member 202 and are located on the two outer side walls of the connector 201. The pair of sliding rods 206 slide on the pair of sliding sleeves 207 respectively, and their ends near the hooks 204 are fixedly connected to the hooks 204. The pair of threaded heads 208 are fixed to the ends of the pair of sliding rods 206 away from the hooks 204. The pair of self-locking nut assemblies 209 are threadedly connected to the pair of threaded heads 208 respectively.

[0038] In use, the length between the claw 204 and the connector 201 is adjusted according to the width of the sensor housing. The length of the slide bar 206 extending from the slide sleeve 207 is adjusted by rotating the position of the self-locking nut assembly 209 on the threaded head 208, thereby adjusting the length between the claw 204 and the connector 201.

[0039] like Figures 3 to 4As shown, a pair of sliding rods 206 each have a spring 210 installed between the sliding sleeve 207 and the self-locking nut assembly 209. The spring 210 provides an elastically deformable space when the hook 204 and the connector 201 lock the first insulation sleeve 1 and the second insulation sleeve 101 together, thus elastically locking the first insulation sleeve 1 and the second insulation sleeve 101 together. Furthermore, after locking, the spring force of the spring 210 pulls the hook 204 towards the connector 201, thereby increasing the locking force between the first insulation sleeve 1 and the second insulation sleeve 101.

[0040] like Figures 3 to 6 As shown, the self-locking nut assembly 209 includes a locking body 213, a nut head 214, a limiting head 215, and a locking nut 217. The locking body 213 is threaded onto the threaded head 208. The nut head 214 and the limiting head 215 are respectively fixed to both ends of the locking body 213. The locking nut 217 is threaded onto the outside of the locking body 213. By screwing the locking nut 217 from one end of the locking body 213 to the other end, the locking body 213 is locked onto the threaded head 208. The limiting head 215 serves two purposes: firstly, to limit the locking nut 217, preventing it from detaching from the locking body 213; and secondly, to press against one end of the spring 210. The nut head 214 serves two purposes: firstly, to drive the locking body 213 to rotate; and secondly, to restrict the rotation of the locking body 213 when the locking nut 217 is rotated, while also limiting the locking nut 217.

[0041] like Figures 3 to 6 As shown, multiple tightening notches 216 are evenly cut on the locking body 213 and the limiting head 215, and one of the tightening notches 216 penetrates the nut head 214. The tightening notch 216 is used to reserve space for the locking body 213 to deform when it is tightened inward. The locking body 213 includes a smooth section 218 and a locking section 219, with the end of the locking section 219 away from the smooth section 218 expanding outward. When the locking nut 217 is screwed to the smooth section 218, the locking body 213 is not tightened inward. At this time, the nut head 214 can drive the locking body 213 to rotate on the threaded head 208, adjusting the position of the self-locking nut assembly 209 on the threaded head 208. When the locking nut 217 is screwed to the locking section 219, the locking nut 217 tightens the locking section 219 of the locking body 213 inward, thereby locking the self-locking nut assembly 209 on the threaded head 208.

[0042] This utility model also discloses a Coriolis mass flow meter, which includes the above-mentioned heat preservation structure.

[0043] Working principle: During installation, the first insulation jacket 1 and the second insulation jacket 101 are placed on both sides of the sensor housing. Then, a pair of flexible straps 107 are routed around the upper pipe, and then the flexible straps 107 are routed around another pair of connecting rods 106 and secured with Velcro 108. The first insulation jacket 1 and the second insulation jacket 101 are then suspended on both sides of the sensor housing.

[0044] Then, based on the width of the sensor housing, the length of the hook 204 extending from the connector 201 is adjusted via the length adjustment mechanism. The length of the slide rod 206 extending from the slide sleeve 207 is adjusted by rotating the position of the self-locking nut assembly 209 on the threaded head 208, thereby adjusting the length between the hook 204 and the connector 201.

[0045] When adjusting the position of the self-locking nut assembly 209 on the threaded head 208, first, use a wrench to fix the nut head 214. Then, use another wrench to turn the locking nut 217, screwing it from the locking section 219 on the locking body 213 to the smooth section 218. The nut head 214 then drives the locking body 213 to rotate on the threaded head 208, thereby adjusting the position of the self-locking nut assembly 209 on the threaded head 208. After adjustment, screw the locking nut 217 from the smooth section 218 on the locking body 213 to the locking section 219, locking the locking body 213 onto the threaded head 208, thus locking the self-locking nut assembly 209 onto the threaded head 208.

[0046] Then, the L-shaped control member 202 is rotated around the fixed shaft seat 203 as the axis. When the L-shaped control member 202 rotates, it drives the connecting member 201 to rotate and move. Through the movement of the L-shaped control member 202 and the connecting member 201, the hook 204 is delivered to the groove 205 and hooked in the groove 205. Then, the L-shaped control member 202 is rotated in the opposite direction, and the locking head 211 is locked onto the locking body 212. This locks and fixes the remaining three side walls of the first insulation jacket 1 and the second insulation jacket 101, so that the first insulation jacket 1 and the second insulation jacket 101 are tightly attached to both sides of the sensor housing.

[0047] After installation, the inlet 102 and outlet 103 on the first insulation jacket 1 and the second insulation jacket 101 are respectively connected to the heat transfer medium delivery pipeline. The heat transfer medium exchanges heat with the sensor shell in the first insulation jacket 1 and the second insulation jacket 101, thereby keeping the sensor warm or raising its temperature.

[0048] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics.
