Description

Technical Field

[0001] This invention belongs to the field of chemical production technology, specifically referring to a dripping device for a reaction vessel in chemical production. Background Technology

[0002] Chemical production reactions are usually carried out in reaction vessels. During the production process, various chemical agents (such as auxiliary agents) are usually added to the reaction vessel. Some chemical agents need to be mixed and reacted before being added to the reaction vessel. The resulting mixture is then added to the reaction vessel to assist chemical production and improve production quality.

[0003] The existing dripping equipment for reactors has the following problems: When existing dripping equipment mixes and reacts raw materials, the change in the properties of some components in the raw materials leads to inconsistent pH values ​​of the reaction solution formed in the dripping equipment, and it is impossible to separate and discharge reaction solutions that meet the requirements from those that do not. Summary of the Invention

[0004] In view of the above situation and to overcome the shortcomings of the existing technology, this solution provides a dripping device for chemical production reactors that can separately discharge compliant and non-compliant reaction solutions.

[0005] The technical solution adopted in this plan is as follows: This plan proposes a dripping device for a reaction vessel in chemical production, including a dripping rack, a reaction cylinder, a dripping cylinder, a drain valve, a reactivity detection mechanism, and a layered storage mechanism. The reaction cylinder is located on the inner wall of the dripping rack, and multiple sets of the dripping cylinders are located at the end of the dripping rack away from the reaction cylinder. The drain valve is connected to the bottom wall of the reaction cylinder. The reactivity detection mechanism is located on the reaction cylinder, and the layered storage mechanism is located on the dripping cylinder. The reactivity detection mechanism includes a uniform reaction mechanism and a testing mechanism. The uniform reaction mechanism is located inside the dripping rack, and the testing mechanism is located on the uniform reaction mechanism. The layered storage mechanism includes a storage mechanism and a dripping mechanism. The storage mechanism is located on the side wall of the reaction cylinder, and the dripping mechanism is located on the side wall of the dripping cylinder.

[0006] As a further preferred embodiment of the present invention, the uniform reaction mechanism includes a reaction motor, a stirring shaft, mixing magnetic plates, a partition plate, a flow port, and an adsorption electromagnet. The reaction motor is located on the upper wall of the reaction cylinder, and the stirring shaft passes through the bottom wall of the reaction cylinder between the power end of the reaction motor and the stirring shaft. The stirring shaft is rotatably located on the bottom wall of the reaction cylinder. Multiple sets of mixing magnetic plates are arranged in pairs on the outside of the stirring shaft. The partition plate is located on the inner wall of the reaction cylinder between the pairs of mixing magnetic plates. Multiple sets of flow ports are located on the upper wall of the partition plate, and the width of the flow ports is the same as the width of the mixing magnetic plates. The adsorption electromagnet is located on the inner wall of the flow ports. The inspection mechanism includes an inspection port, an inspection cylinder, adsorption cotton, a threaded plate, an alkalinity meter, and a fixed magnet. The test tube comprises a suction port, a sealing magnetic plate, and a sealing spring. Multiple test ports are located on the upper wall of a partition plate. A test cylinder penetrates the reaction cylinder and is located inside the test port. The test cylinder has an open top. The absorbent cotton is slidably located inside the test cylinder. A threaded plate is located at the end of the test cylinder away from the reaction cylinder and is threadedly connected to the test cylinder. An alkalinity meter is located on the side of the threaded plate away from the test cylinder. The detection end of the alkalinity meter penetrates the threaded plate and is located inside the test cylinder. The detection end of the alkalinity meter is inserted inside the absorbent cotton. Multiple fixed magnets are located outside the stirring shaft. The suction port is spirally arranged from top to bottom on the side wall of the test cylinder. The sealing magnetic plate is located on one side of the suction port. The sealing spring is located between the test cylinder and the sealing magnetic plate.

[0007] In initial use, the test tube is pulled out of the reaction cylinder, and the reaction materials are placed inside. The reaction motor then drives the stirring shaft to rotate, which in turn rotates the mixing magnetic plate to stir the chemical materials inside the reaction cylinder, promoting a mixing reaction. Once the reaction time of the chemical materials inside the reaction cylinder reaches the user's desired duration, the reaction motor stops driving the stirring shaft. Due to inertia, the stirring shaft will remain stationary for an extended period. At this time, the electromagnet is energized and generates magnetism. The electromagnet and the mixing magnetic plate are set with opposite poles. The electromagnet is fixed inside the flow port and magnetically attracts the mixing magnetic plate, fixing it at the opening of the flow port. This blocks and cuts off the passage connecting the various cavities. The test tube is inserted through the reaction cylinder into the test port inside the reaction cylinder, with the bottom wall of the test tube fitting against the bottom wall of the reaction cylinder. The sealing spring is in a shortened state, and the shortening of the sealing spring drives the sealing magnetic plate. The sealing spring is located on the side wall of the test cylinder to seal it. When the test cylinder slides into the reaction cylinder, the sealing magnetic plate is located on the side of the test cylinder close to the inner wall of the reaction cylinder. After the bottom wall of the test cylinder is in contact with the bottom wall of the reaction cylinder, the test cylinder is rotated. The test cylinder drives the sealing magnetic plate to a position opposite to the fixed magnet. The fixed magnet and the sealing magnetic plate are set with opposite poles. The fixed magnet is fixed on the outside of the stirring shaft and attracts the sealing magnetic plate by magnetic force. The sealing magnetic plate moves away from the inside of the suction port by the deformation of the sealing spring. At this time, the reaction liquid inside the cavity between the partition plate and the bottom wall of the reaction cylinder enters the test cylinder through the suction port. The reaction liquid wets the absorbent cotton. The absorbent cotton guides the reaction liquid to the end of the test cylinder close to the alkalinity meter. Then, the detection end of the alkalinity meter measures the acidity and alkalinity of the reaction liquid inside the absorbent cotton. After the measurement, the test cylinder is manually rotated. The test cylinder drives the sealing magnetic plate away from the fixed magnet. The sealing spring elastically resets and causes the sealing magnetic plate to seal the suction port.

[0008] Preferably, the liquid storage mechanism includes a liquid pump, a liquid pumping pipe, an electric valve, a liquid outlet pipe, and a dripping mechanism. Multiple sets of the liquid pumps are symmetrically arranged vertically on the sidewalls of the reaction cylinder. The liquid pumping pipe passes through the reaction cylinder and the partition plates located on the inner walls at both ends of the reaction cylinder. The pipe is positioned on the sidewall of the partition plate located on the inner wall of the middle section of the reaction cylinder. A cavity is formed between the partition plate and the upper wall of the reaction cylinder, a cavity is formed between the partition plate and the bottom wall of the reaction cylinder, and a cavity is formed between the partition plates. Multiple sets of the electric valves are connected to the sidewalls of the liquid pumping pipe inside the reaction cylinder. The actuating valve is located inside the cavity formed between the partition plate and the upper wall of the reaction cylinder, the cavity formed between the partition plate and the bottom wall of the reaction cylinder, and the cavity formed between the partition plates. The liquid outlet pipe passes through the drip rack and is connected between the liquid discharge end of the pump. The dripping mechanism includes a one-way valve, a dripping pipe, and a dripping valve. The one-way valves are symmetrically arranged on both sides of the dripping cylinder and are connected to the dripping cylinder. The dripping pipe passes through the reaction cylinder and is connected between the one-way valve and the liquid outlet pipe. The dripping valve is connected to the bottom wall of the dripping cylinder.

[0009] In use, when the reaction liquid inside the cavity between the partition plate and the bottom wall of the reaction cylinder meets the user's requirements, the electric valve inside the cavity between the partition plate and the bottom wall of the reaction cylinder opens, connecting the cavity between the partition plate and the bottom wall of the reaction cylinder to the suction pipe. The suction pump, through the electric valve and the suction pipe, draws the reaction liquid inside the cavity between the partition plate and the bottom wall of the reaction cylinder into the outlet pipe. The outlet pipe then delivers the reaction liquid meeting the requirements to the dropping cylinder for storage via the dropping pipe. Subsequently, the threaded plate is rotated, and the threaded plate is removed from the end of the test cylinder away from the reaction cylinder. The soaked absorbent cotton inside the test cylinder is removed, and new absorbent cotton is placed inside the test cylinder to facilitate the measurement of the reaction liquid inside other cavities inside the reaction cylinder. Continuing to rotate the test cylinder, the sealing magnetic plate in the cavity between the partition plates rotates to be positioned opposite the fixed magnet on the side wall of the stirring shaft. The fixed magnet is fixed to the outside of the stirring shaft and magnetically attracts the sealing magnetic plate. The sealing magnetic plate is moved away from the suction port by the deformation of the sealing spring, thus separating the partition plate. The reaction liquid inside the cavity between the plate and the partition plate enters the test cylinder to wet the adsorption cotton. The alkalinity meter measures the reaction liquid adsorbed inside the adsorption cotton through the detection end. When the measured value meets the user's requirements, the electric valve inside the cavity between the partition plates opens, and the liquid pump draws the reaction liquid inside the cavity between the partition plates into the dropping cylinder for storage. The above method is repeated to measure the reaction liquid inside the cavity between the partition plate and the upper wall of the reaction cylinder. When the value of the reaction liquid inside the cavity between the partition plate and the upper wall of the reaction cylinder does not meet the user's requirements, after the reaction liquid in other cavities that meets the requirements is drawn out, the adsorption electromagnet is de-energized and demagnetized. The reaction motor drives the mixing magnetic plate to be offset from the flow port through the stirring shaft, so that the reaction liquid inside the cavity can flow into the bottom wall of the reaction cylinder through the flow port. Then, the drain valve is opened to discharge the waste liquid. The external pipeline connects the dropping valve to the reaction vessel, and the dropping valve is opened to allow the reaction liquid inside the dropping cylinder to enter the reaction vessel.

[0010] Specifically, a controller is provided on the side wall of the reaction cylinder.

[0011] The controller is electrically connected to the reaction motor, alkalinity meter, liquid pump and electric valve respectively.

[0012] The beneficial effects achieved by this solution using the above structure are as follows: Compared with existing technologies, this solution adopts a layered sealing method, which can measure the acidity and alkalinity of the reaction liquid inside the reaction cylinder separately. Under the action of the layered liquid storage mechanism, the reaction liquid that meets the user's requirements is added dropwise for use, and the reaction liquid that does not meet the user's requirements is discharged as waste liquid. When the values ​​of the reaction liquid inside the partition plate and the upper wall cavity of the reaction cylinder do not meet the user's needs, after the reaction liquid that meets the requirements in other cavities is extracted, the adsorption electromagnet is de-energized and demagnetized. The reaction motor drives the mixing magnetic plate to be misaligned with the flow port through the stirring shaft, so that the reaction liquid inside the cavity can flow into the bottom wall of the reaction cylinder through the flow port. Then, the drain valve is opened to discharge the waste liquid. The external pipeline connects the dripping valve to the reaction vessel. Opening the dripping valve allows the reaction liquid inside the dripping cylinder to enter the reaction vessel. Attached Figure Description

Multiple sets of the liquid pump 25 are symmetrically arranged vertically on the side walls of the reaction cylinder 2.

The dripping valve 32 is connected to the bottom wall of the dripping cylinder 3.

[0021] The side wall of the reaction cylinder 2 is equipped with a controller 33.

[0022] The controller 33 is electrically connected to the reaction motor 7, the alkalinity meter 18, the liquid pump 25, and the electric valve 27, respectively.

[0023] In specific use, in Example 1, initially, the test cylinder 15 is pulled out of the reaction cylinder 2, and the reaction raw materials are placed into the reaction cylinder 2. Then, the controller 33 controls the reaction motor 7 to start. The reaction motor 7 drives the stirring shaft 8 to rotate via its power end. The stirring shaft 8 drives the mixing magnetic plate 9 to rotate, stirring the chemical raw materials inside the reaction cylinder 2 and promoting the mixing reaction. When the reaction time of the chemical raw materials inside the reaction cylinder 2 reaches the user's required time, the controller 33 controls the reaction motor 7 to stop, and the reaction motor 7 stops driving the stirring shaft 8 to rotate. Due to inertia, the stirring shaft 8 will take longer to stop rotating. At this time, the controller 33 controls the activation of the adsorption electromagnet 12. The adsorption electromagnet 12 is energized and generates magnetism. The adsorption electromagnet 12 and the mixing magnetic plate 9 are set with opposite poles. The adsorption electromagnet 12 is fixed inside the flow port 11 and magnetically adsorbs the mixing magnetic plate 9. The mixing magnetic plate 9 is fixed at the opening of the flow port 11, thereby blocking and cutting off the passage between the flow port 11 and the various cavities. The test cylinder 15 penetrates the reaction cylinder 2 and is inserted into the test port 14 inside the reaction cylinder 2. The bottom wall of the test cylinder 15 is in contact with the bottom wall of the reaction cylinder 2. The sealing spring 22 is in the shortened state. The shortening of the sealing spring 22 drives the sealing... The magnetic plate 21 is located on the side wall of the test cylinder 15 to seal the sealing spring 22. When the test cylinder 15 slides into the reaction cylinder 2, the sealing magnetic plate 21 is located on the side of the test cylinder 15 closest to the inner wall of the reaction cylinder 2. After the bottom wall of the test cylinder 15 is in contact with the bottom wall of the reaction cylinder 2, the test cylinder 15 is rotated. The test cylinder 15 drives the sealing magnetic plate 21 to a position opposite to the fixed magnet 19. The fixed magnet 19 and the sealing magnetic plate 21 are set with opposite poles. The fixed magnet 19 is fixed on the outside of the stirring shaft 8 and magnetically attracts the sealing magnetic plate 21. The sealing magnetic plate 21 is deformed away from the inside of the suction port 20 by the sealing spring 22. At this time, the reaction liquid inside the cavity between the partition plate 10 and the bottom wall of the reaction cylinder 2 enters the interior of the test cylinder 15 through the suction port 20. The reaction liquid wets the absorbent cotton 16, and the absorbent cotton 16 guides the reaction liquid to the end of the test cylinder 15 near the alkalinity measuring meter 18. Then, the controller 33 controls the alkalinity measuring meter 18 to start. The detection end of the alkalinity measuring meter 18 measures the acidity and alkalinity of the reaction liquid inside the absorbent cotton 16. After the measurement, the test cylinder 15 is manually rotated. The test cylinder 15 moves the sealing magnetic plate 21 away from the fixed magnet 19. The sealing spring 22 elastically resets and moves the sealing magnetic plate 21 to seal the suction port 20. When the reaction liquid inside the cavity between the partition plate 10 and the bottom wall of the reaction cylinder 2 meets the user's requirements, the controller 33 controls the electric valve 27 inside the cavity between the partition plate 10 and the bottom wall of the reaction cylinder 2 to open, and the cavity between the partition plate 10 and the bottom wall of the reaction cylinder 2 is connected to the extraction pipe 26. The extraction pump 25 extracts the reaction liquid inside the cavity between the partition plate 10 and the bottom wall of the reaction cylinder 2 through the electric valve 27 and the extraction pipe 26 into the outlet pipe 28. The outlet pipe 28 delivers the reaction liquid that meets the requirements to the dropper 31 for storage. Then, the threaded plate 17 is rotated, and the threaded plate 17 moves away from the test cylinder 15 away from the reaction cylinder 2. Remove one end of the test cylinder 15 and take out the soaked absorbent cotton 16 inside. Place new absorbent cotton 16 inside the test cylinder 15 to facilitate the measurement of the reaction liquid inside other cavities inside the reaction cylinder 2. Continue to manually rotate the test cylinder 15. The sealing magnetic plate 21 in the cavity between the partition plates 10 rotates to be positioned opposite the fixed magnet 19 on the side wall of the stirring shaft 8. The fixed magnet 19 is fixed to the outside of the stirring shaft 8 and magnetically attracts the sealing magnetic plate 21. The sealing magnetic plate 21 is deformed away from the inside of the suction port 20 by the sealing spring 22. The reaction liquid inside the cavity between the partition plates 10 enters the cavity. The test cylinder 15 is filled with absorbent cotton 16. The alkalinity meter 18 measures the reaction liquid adsorbed inside the absorbent cotton 16 through the detection end. When the measured value meets the user's requirements, the controller 33 controls the electric valve 27 inside the cavity between the partition plate 10 and the partition plate 10 to open. The controller 33 controls the electric valve 27 inside the cavity between the partition plate 10 and the bottom wall of the reaction cylinder 2 to close. The pump 25 draws the reaction liquid inside the cavity between the partition plate 10 and the partition plate 10 into the dropping cylinder 3 for storage. The above method is repeated to measure the reaction liquid inside the cavity between the partition plate 10 and the upper wall of the reaction cylinder 2. When the partition plate 10 If the reaction liquid level inside the upper wall cavity of reaction cylinder 2 does not meet the user's requirements, after the reaction liquid in other cavities that meet the requirements is extracted, controller 33 controls the adsorption electromagnet 12 to de-energize and demagnetize. Controller 33 controls the reaction motor 7 to drive the mixing magnetic plate 9 to be offset from the flow port 11 via the stirring shaft 8, so that the reaction liquid inside the cavity can flow into the bottom wall of reaction cylinder 2 through the flow port 11. Then, the drain valve 4 is opened to discharge the waste liquid. An external pipeline connects the drip valve 32 to the reactor, and the drip valve 32 is opened to allow the reaction liquid inside the drip cylinder 3 to enter the reactor. The above operation can be repeated for the next use.
