Description

Technical Field

[0001] The invention relates to the technical field of hydrogen peroxide production equipment, and more specifically to a multi-reaction vessel continuous feeding online detection device. Background Art

[0002] Industrial hydrogen peroxide needs to be acidified to control the pH value in industrial production, so that it is controlled at the required pH value for industrial production. The prior art document with publication number CN211998817U provides an acid-adding device for a hydrogen peroxide production system, which can add quantitatively multiple times through mixing in a mixing box and automatic addition in an addition box. The entire detection process can be cyclically carried out through automatic detection of the detector and the operation of the engineering pump. However, the device is used after mixing in a mixing box, and cannot be used on multiple reaction vessels at the same time, which reduces the efficiency of continuous acid addition and mixing. At the same time, the device can only detect the pH value of the current mixing box at a time, and the detection efficiency is low, which affects the production demand for different pH values ​​of hydrogen peroxide, and cannot be detected and mixed in time to achieve the purpose of controlling the pH value. In view of this, we propose a multi-reaction vessel continuous feeding online detection device. Summary of the invention

DETAILED DESCRIPTION

[0028] See also Figure 1-6 , the present invention provides a technical solution:

[0029] The invention discloses an online detection device for continuous feeding of multiple reaction vessels, comprising a working box 1, wherein the bottom surface of the working box 1 is annular and has multiple supporting legs 2 at equal intervals, two windows 3 are symmetrically provided on one side of the circumferential outer wall of the working box 1 for convenient observation of the internal situation of the working box 1, an acid adding bottle 4 is provided on the upper side of the working box 1, a reading screen is provided on the other side of the circumferential outer wall of the working box 1, which can be used to display the detection results online, and replace the manual analysis with the online real-time analysis, a machine case 102 is provided in the middle of the bottom surface of the working box 1, a motor A103 is provided inside the machine case 102, an output end of the motor A103 extends through the inner wall of the machine case 102 to the inside of the working box 1 and is sleeved with a rotating block 104, an annular groove B105 is provided on the circumferential outer wall of the rotating block 104, a plurality of reaction vessels 106 are symmetrically provided on the upper side of a fixing ring 107 connected and fixed to the rotating block 104 in an annular and equal-interval manner, an acid adding tube 5 is provided on one side of the circumferential inner wall of the working box 1, as shown in FIG. Figure 6As shown, the outer end of the acid adding tube 5 is connected with an L-shaped tube 501, the upper end of the L-shaped tube 501 passes through the inner wall of the working box 1 through a hose and extends to the outside and is connected to the lower end of the acid adding bottle 4, a spring A502 is provided in the middle of the L-shaped tube 501, and a sealing block A503 is provided at the upper end of the spring A502. A hollow piston 504 is slidably connected inside the acid adding tube 5, and one side of the hollow piston 504 is fixed and connected with an action tube 505, and a through hole 506 is opened on one side of the circumferential outer wall of the action tube 505, a spring B507 is provided inside the action tube 505, and a sealing block B508 is provided at the inner end of the spring B507. Through two springs The two sealing blocks are pushed to slide inside the corresponding pipes respectively. The cylindrical end of the action tube 505 passes through the inner wall of the acid adding tube 5 and extends to the outside and is provided with an inclined groove 509. An inclined rod 5010 is provided on the upper side of the acid adding tube 5. The inclined groove 509 is slidably connected to the inclined rod 5010. A ball 5012 is provided at one end of the inclined rod 5010. The annular groove B105 is rollingly connected to the ball 5012. The ball 5012 slides inside the annular groove B105, which can drive the inclined rod 5010 to slide inside the inclined groove 509, and the displacement component of the inclined rod 5010 in the horizontal direction can push the action tube 505 to move horizontally.

[0030] In this embodiment, the controller drives the output shaft of the motor A103 to rotate, thereby driving the rotating block 104 to rotate. The annular groove B105 of the rotating block 104 drives the rolling ball 5012 and the inclined rod 5010 to slide along the annular groove B105. The movement trajectory of the rolling ball 5012 and the inclined rod 5010 is the changing structure of the annular groove B105 in the vertical direction. Through the sliding cooperation between the inclined rod 5010 and the inclined groove 509, the movement of the inclined rod 5010 in the vertical direction can push the action tube 505 to move in the horizontal direction.

[0031] The horizontal movement of the action tube 505 can drive the hollow piston 504 to move. When the action tube 505 and the hollow piston 504 move away from the L-shaped pipe 501, the sealing block B508 is tightly pressed against the through hole of the hollow piston 504, closing the flow channels on both sides of the hollow piston 504. As the space in the acid adding pipe 5 close to the L-shaped pipe 501 gradually expands, the pressure in the space gradually decreases, forming a negative pressure with the outside, so that the sealing block A503 is separated and squeezes the spring A502. At this time, the acid solution can flow into the acid adding pipe 5 through the L-shaped pipe 501;

[0032] When the action tube 505 and the hollow piston 504 subsequently move toward the side close to the L-shaped pipe 501, the space in the acid adding pipe 5 close to the L-shaped pipe 501 gradually shrinks, causing the pressure in the space to gradually increase, and the spring A502 pushes the sealing block A503 to close the L-shaped pipe 501. At this time, the acid solution no longer flows into the acid adding pipe 5. At the same time, the acid solution pushes the sealing block B508 to squeeze the spring B507 to open the two-side flow channels of the hollow piston 504, and the acid solution can enter the other side of the acid adding pipe 5 through the hollow piston 504, thereby performing acid addition treatment on the reaction vessel 106. During the process of rotating the rotating block 104 for one rotation, the reciprocating movement of the action tube 505 is circulated for multiple times, so that acid addition treatment can be performed on multiple reaction vessels 106.

[0033] In order to detect multiple reaction vessels 106 in sequence, a detection box 6 is provided on one side of the upper wall inside the working box 1, and two support rods 601 are symmetrically fixed inside the detection box 6, and two limit rotating blocks 602 are symmetrically rotatably connected on the rotating shaft on the lower side of the middle part of the support rod 601, and two limit rods 603 are symmetrically provided inside the detection box 6, and a limit groove 604 is provided in the middle part of the limit rod 603, and the limit rotating block 602 is slidably connected to the limit groove 604, and the front end of the limit rod 603 is rotatably connected to the three-connecting rod 605 through a pin shaft, and the rear end of the three-connecting rod 605 is rotatably connected to the L-shaped rod 606 through a pin shaft, and the upper end of the L-shaped rod 606 is rotatably connected to the swing rod 607 through a pin shaft, and a detector 608 is provided at the lower end of the swing rod 607, the rear end of the limit rod 603 is rotatably connected to the middle part of the swing rod 607 through a pin shaft, and the three-connecting rod 605 is rotatably connected to one end of the support rod 601 through a rotating shaft.

[0034] In this embodiment, if Figure 5 As shown, the limit rod 603, the three-connecting rod 605, the L-shaped rod 606 and the swing rod 607 can form a closed connecting rod rotating mechanism. The three-connecting rod 605 is driven to rotate around the rotating shaft by the motor repeatedly rotating forward and reversely. The rotation of the three-connecting rod 605 will inevitably drive the limit rod 603 and the L-shaped rod 606 connected at both ends to rotate. With the cooperation of the limit rotating block 602 rotating around the rotating shaft connected to it and sliding inside the limit groove 604, the limit rotating block 602 can rotate around the rotating shaft connected to it and slide inside the limit groove 604. Figure 5For example, when the three-connecting rod 605 rotates counterclockwise, the L-shaped rod 606 and the swing rod 607 rotate downward, and the limiting rod 603 rotates upward, so that the angle between the three-connecting rod 605 and the L-shaped rod 606 and the angle between the limiting rod 603 and the swing rod 607 gradually decrease, and the angle between the L-shaped rod 606 and the swing rod 607 gradually increases, so that the swing rod 607 moves obliquely downward, so that the detector 608 can extract and detect the solution in the reaction vessel 106. During the entire process of needle rotation, the limit rotating block 602 slides along the limit slot 604 from the middle to the side connected to the swing rod 607, and then slides to the other side of the limit slot 604, thereby dividing the movement of the swing rod 607 into two corresponding stages. The horizontal displacement component of the first stage is significantly greater than that of the second stage, and the vertical displacement component of the second stage is also significantly greater than the horizontal displacement component; conversely, when the three-connecting rod 605 rotates clockwise, the swing rod 607 moves obliquely upward along the original path to retract the detector 608.

[0035] In the above embodiment, frequent forward and reverse rotation of the motor may easily cause damage to the motor. For this reason, a motor B7 is provided at one end of the outer side of the detection box 6. The output end of the motor B7 extends through the outer wall of the detection box 6 and the inside of the support rod 601 to the outside and is sleeved and fixed with a double rod 701. The front end of the double rod 701 is rotatably connected to the connecting rod 702 through a pin shaft. The front end of the connecting rod 702 is rotatably connected to the sliding column 703 through a hinge seat. The front end of the sliding column 703 is rotatably connected to the V-shaped rod 704 through a hinge seat. The front end of the V-shaped rod 704 is rotatably connected to the sleeve 705 through the hinge seat. The sleeve 705 is sleeved and fixed on a rotating shaft connected to one end of the three-connecting rod 605, so that the sleeve 705 and the three-connecting rod 605 rotate coaxially and synchronously.

[0036] In this embodiment, the controller drives the output shaft of the motor B7 to rotate, thereby driving the double rod 701 to rotate, and then driving the connecting rod 702 to rotate around the connection between it and the double rod 701 and move at the same time, and then driving the V-shaped rod 704 to rotate and move through the sliding column 703, thereby driving the sleeve 705 to rotate back and forth. Since the sleeve 705 and the three-connecting rod 605 are connected and fixed by a rotating shaft, the sleeve 705 can drive the three-connecting rod 605 to rotate back and forth.

[0037] The coordination between the structures enables the device to perform acid addition and proportioning on multiple reaction vessels 106 at the same time, and the reaction vessels 106 are switched by rotating the rotating block 105, so that the acid addition and proportioning can be performed continuously, thereby improving the mixing and working efficiency.

[0038] Specifically, an annular groove A101 is provided on the inner bottom surface of the working box 1, and the annular groove A101 is slidably connected with an annular track provided in the middle of the bottom surface of the rotating block 104, so that the rotating block 105 can only perform a rotating action.

[0039] Further, the annular groove B105 is arranged in a wavy structure, and the side slopes on both sides of a wave of the annular groove B105 are different along the rotation direction of the rotating block 104. The annular groove B105 is arranged in a wavy structure, so that the connecting column 5011 moves up and down, thereby driving the piston 504 through the inclined rod 5010, so that it can intermittently add acid through the acid delivery pipe. The different side slopes on both sides of a wave can make the time for the acid solution to be drawn in and squeezed out different.

[0040] Furthermore, a limiting slide 706 is provided between the two support rods 601 through a fixed block, and the limiting slide 706 is slidably connected to the slide post 703. The double rods 701 rotate to drive the connecting rod 702, thereby making the slide post 703 reciprocate.

[0041] It should be noted that other connection methods can be used to replace the sliding connection between the inclined rod 5010 and the inclined groove 509. For example, a connecting column 5011 is rotatably connected to one end of the inclined rod 5010, and a ball 5012 is rotatably connected to one end of the connecting column 5011. The ball 5012 is stuck in the annular groove B105. The inclined rod 5010 and the action tube 505 are connected and fixed, and the connection angle between the two is not limited.

[0042] When the rolling ball 5012 slides in the annular groove B105 , the connecting column 5011 can be driven to rotate, and the horizontal displacement component of the rotation is compensated by the horizontal movement of the action tube 505 .

[0043] When the online detection and continuous acid addition simulation device for industrial hydrogen peroxide production is needed, first, the reaction vessel 106 is placed on the fixed ring 107 and stuck. At this time, the output shaft of the motor A103 is driven to rotate by the controller. Since the output end of the motor A103 passes through the inner wall of the chassis 102 and extends to the inside of the working box 1 and is sleeved with a rotating block 104, the outer wall of the rotating block 104 is provided with an annular groove B105, and the annular groove B105 is arranged in a wavy structure. The annular groove B105 is rollingly connected to the rolling ball 5012, and the inclined groove 509 is slidingly connected to the inclined rod 5010. The annular groove B105 is arranged in a wavy structure, and the piston 504 is driven to reciprocate by the inclined rod 5010. At this time, since the piston 504 reciprocates and forms a negative pressure when it moves inward, the sealing block A503 is disengaged, and the spring B507 pushes the sealing block B508 to close. At this time, the acid flows in, and when it moves toward During the outward movement, the spring A502 pushes the sealing block A503 to close, and the sealing block B508 is pushed open due to the pressure, thereby acidifying the reaction vessel 106, even if it can be acidified through the acid delivery pipe in intervals, and so on. At the same time, after the rotating block 104 drives the fixed ring 107 to rotate, when the reaction vessel 106 reaches the lower side of the detection box 6, at this time, the output shaft of the motor B7 is driven to rotate by the controller, and the output end of the motor B7 extends through the outer wall of the detection box 6 and the inside of the support rod 601 to the outside and is sleeved with a double rod 701. The double rod 701 rotates to drive the connecting rod 702, so that the sliding column 703 slides back and forth, and then drives the sleeve 705 to rotate back and forth through the V-shaped rod 704, thereby driving the three-connecting rod 605 to change its angle, so that the limit rod 603 reverses downward, so that the detector 608 on the swing rod 607 reaches the reaction vessel 106 for detection.
