Description

TECHNICAL FIELD

[0002] In the chemical production process, flow regulation is a key link to ensure the stability of production process and the qualification of product quality. As the core equipment for fluid flow control, the regulation performance of the chemical flowmeter directly affects the production efficiency and cost. The traditional chemical flowmeter needs to meet the flow regulation requirements under different production conditions, including the adjustment of the overall flow proportion of multiple shunt channels and the independent fine control of the flow of a single shunt channel to adapt to the differentiated requirements for fluid delivery in different stages of chemical reaction. However, the early flowmeters often have difficulty in balancing the operation convenience and regulation accuracy in structural design, and have exposed many problems in actual application.

[0003] The traditional chemical flowmeter has obvious defects in the flow regulation mechanism. When the overall shunt flow is regulated, there is a lack of efficient linkage transmission structure, and the operator needs to adjust each shunt valve individually, which is not only tedious and time-consuming, but also difficult to ensure the consistency of the adjustment range of each shunt valve, resulting in unbalanced shunt proportion. When a shunt valve needs to be adjusted individually, there is no convenient linkage release method, and usually the connection between the shunt valve and the main regulating mechanism needs to be disconnected by disassembling part of the transmission components, which is complicated and easy to cause wear to the equipment. At the same time, the adjustment process is easily disturbed by other shunt valves, which cannot achieve precise independent control and cannot meet the high requirements of flow regulation efficiency and accuracy in chemical production, seriously restricting the improvement of production rhythm.

[0049] In actual operation, when the device is used, the flow regulating control and filter screen cleaning operation of the chemical flowmeter are as follows

[0050] In the chemical production process, the flow regulating control and anti-blocking maintenance of the chemical flowmeter are key links to ensure the stability of fluid delivery. The flow regulating control principle and filter screen cleaning process are described in detail as follows:

[0051] I. Flow regulating control operation

[0052] Whole split flow regulating

[0053] When the whole split flow of the flowmeter needs to be regulated, the fluid enters from the left end inlet of the valve body 1, flows to the right along the internal flow channel of the valve body, and finally completes split output through the multiple individual split valves 211 arranged at the right end. At this time, the regulating operation is realized through the main transmission mechanism: the operator only needs to rotate the main dial ring 2135, which will directly drive the main gear 2131 fixedly connected thereto to rotate synchronously. Since the main gear 2131 is in meshing connection with the two slave gears 2132, the rotation of the main gear 2131 will be accurately transmitted to the two slave gears 2132, so as to drive the slave gears 2132 to rotate synchronously. When the slave gears 2132 rotate, the connecting rod 214 rigidly connected thereto will also rotate, and the valve core 2198 connected to the other end of the connecting rod 214 will rotate in the respective corresponding split valve 211. The rotation of the valve core 2198 changes the flow area between the valve core 2198 and the inner wall of the split valve 211, thereby realizing synchronous regulating control of the flow of each split valve 211, and ensuring that the whole split ratio meets the production requirements.

[0054] II. Individual split valve flow regulating

[0055] If the flow of a certain split valve 211 needs to be regulated individually in the production process, the individual control needs to be realized by disengaging the linkage mechanism, and the specific operation steps are as follows:

[0056] Release sliding limit: the operator first holds the sliding sleeve 222 corresponding to the position of the flow divider valve 211, ensures that the hand is stable, hooks the L-shaped strip 225 with the fingers and pulls it outward; the L-shaped strip 225 is fixedly connected with the sliding block 224, and pulling the L-shaped strip 225 will drive the sliding block 224 to move in the sliding channel inside the sliding sleeve 222 away from the positioning vertical bar 221; when the sliding block 224 moves, the clamping rod 226 connected with it will move synchronously and gradually disengage from the clamping groove inside the positioning vertical bar 221, at which time the up-down sliding limit of the sliding sleeve 222 on the positioning vertical bar 221 is released;

[0057] Release linkage control: after the sliding limit is released, the operator can move the sliding sleeve 222 upward, which will drive the hollow circular bar 215 connected with it to move synchronously; since the hollow circular bar 215 is sleeved outside the supporting rod 214, the supporting rod 214 will limit the movement of the hollow circular bar 215, ensuring that it moves stably along the axial direction; when the hollow circular bar 215 moves, it will drive the positioning ring seat 216 at the top to lift up, so that the positioning ring seat 216 gradually disengages from the clamping structure on the surface of the clamping strip 217; after the positioning ring seat 216 disengages from the clamping, the mechanical linkage between the supporting rod 214 and the main lever 213 is cut off, at which time when the main lever 213 rotates, its power cannot be transmitted to the supporting rod 214 through the meshing of the first transmission wheel 2193 and the second transmission wheel 2195;

[0058] Single adjustment operation: after the linkage is released, the operator can directly rotate the supporting rod 214 or the related adjustment components corresponding to the flow divider valve 211 to individually control the rotation angle of the valve core 2198, so as to realize precise adjustment of the flow of the flow divider valve 211. The entire single adjustment process realizes quick linkage switching through the clamping and disengaging of the clamping rod 226 and the positioning vertical bar 221, and the clamping and disengaging of the positioning ring seat 216 and the clamping strip 217, and the adjustment operation is convenient and efficient;

[0059] II. Filter screen cleaning operation

[0060] In order to prevent impurities in the fluid from blocking the flow channel of the flowmeter, the equipment is provided with a filter screen 33 inside the valve body 1, and its cleaning and maintenance process is as follows:

[0061] I. Release the fixing limit of the filter screen

[0062] When the filter screen 33 needs to be cleaned, first, the fixing structure thereof needs to be released: the double-shaft motor 43 is started, the output shaft of the double-shaft motor 43 drives the screw rod 44 to rotate; the screw rod 44 is connected with the threaded strip 45 through threads, the rotation of the screw rod 44 is converted into the linear sliding of the threaded strip 45; the T-shaped guide block 46 connected at the bottom of the threaded strip 45 slides synchronously with the threaded strip 45 in the T-shaped slide way inside the hollow seat 41; when the T-shaped guide block 46 slides, the T-shaped short strip two 49 at the end portion thereof pushes the long rod 47 to move, the long rod 47 is connected with the short rod 48 through the hinged structure, the movement of the long rod 47 drives the short rod 48 to rotate around the hinge point and to displace; the T-shaped short strip one 481 connected at the other end of the short rod 48 moves with the short rod 48, and then pushes the limiting block 38 to slide in the slide way inside the horizontal seat 36; when the limiting block 38 slides, it drives the two T-shaped rods 39 connected therewith to move synchronously, so that the T-shaped rods 39 gradually disengage from the clamping holes inside the top strip 31, at this time, the fixing limit of the filter screen 33 is completely released.

[0063] The filter screen is taken out for cleaning

[0064] After the T-shaped rods 39 disengage from the clamping position of the top strip 31, the second spring 351 inside the valve body 1 releases the elastic potential energy: one end of the second spring 351 is fixed to the inner wall of the valve body 1, the other end is connected with the T-shaped block 35, the elastic force thereof pushes the T-shaped block 35 to slide upwards in the slide way inside the valve body 1; when the T-shaped block 35 slides upwards, it drives the plug strip 34 and the filter frame 32 connected therewith to pop up synchronously, the filter screen 33 inside the filter frame 32 is lifted up together with the filter frame 32, at this time, the operator can easily take out the filter screen 33 from the filter frame 32; after the filter screen 33 is thoroughly cleaned and impurities are removed, it is put back to the original position in the reverse order, and the anti-blocking function of the flowmeter is restored, so that the smooth flow of fluid in the equipment is ensured.
