Description
Technical Field
[0001] This utility model specifically relates to an auxiliary material feeding device, belonging to the technical field of production reactor feeding equipment. Background Technology
[0002] A reaction vessel is a batch reactor equipped with a stirring device, typically consisting of a vessel body, a stirrer, a heating / cooling system, and a sealing device. The heating / cooling system of the reaction vessel allows for precise temperature control of the reaction system, maintaining the reaction under optimal conditions. The stirring device within the reaction vessel ensures uniform mixing of materials, promotes full contact of reactants, and accelerates the chemical reaction. During the synthesis reaction, various auxiliary materials need to be added intermittently or continuously to the main material in the reaction vessel to ensure complete reaction between the main and auxiliary materials. Existing reaction vessels include, for example, a curing agent mixing device with a temperature-controlled jacket disclosed in Chinese Patent Publication No. CN222998790U, which includes a reaction vessel. The reactor body has a jacket fixedly installed on its outer side, and multiple feed pipes are fixedly installed on the top cover. A manhole is also opened on the top cover between two of the feed pipes. A guide cover is fixedly installed at one end of the multiple feed pipes inside the top cover, and the guide cover is placed inside the top cover. At the same time, a rotating cover is rotatably installed inside the top cover. A distribution plate is fixedly installed at the lower end of the rotating cover. Multiple guide grooves are opened on the distribution plate, and multiple discharge holes are opened at the bottom of the guide grooves, so that external auxiliary materials can be introduced into the cavity between the rotating cover and the distribution plate through the feed pipes and the guide cover. However, this structure cannot accurately control the amount and rate of addition of auxiliary materials. In addition, the added auxiliary materials cannot be fully dispersed into the main material, and local aggregation is likely to occur. Utility Model Content
[0003] To address the aforementioned problems, this utility model proposes an auxiliary material feeding device that can precisely control the amount and rate of auxiliary material feeding, and ensure that the auxiliary material is in full contact with the main material.
[0004] The auxiliary material feeding device of this utility model includes: The controller for the entire production reactor; An oblique tee pipe, wherein the bottom of the oblique tee pipe is integrally formed with a threaded pipe, and the bottom of the oblique tee pipe is connected to the manhole or auxiliary material inlet of the production vessel through a flange; A feeding rotary valve, the bottom of which is fixed to the top of a slanted tee pipe via a flange; a feeding unit is connected to the top of the feeding rotary valve via a flange. A jetting pipeline, wherein the jetting pipeline is connected to a pressurized gas source via a pressure regulating valve; The material distributor includes a material distribution cover disposed inside the production vessel and screwed to a threaded tube. The lower part of the inner side of the material distribution cover is integrally formed with multiple retaining rings. A threaded groove is provided below the retaining rings. A pressure-relief tube seat is screwed onto the threaded groove. A dispersion filter screen is disposed between the pressure-relief tube seat and the retaining rings.
[0005] When the auxiliary material is fed, it enters the feeding rotary valve and is metered by rotating the valve. The metered auxiliary material is then fed to the bottom of the feeding rotary valve and then into the inclined tee pipe. Pressure air is then injected into the spray pipeline through the pressure air source and pressure regulating valve, so that the auxiliary material in the inclined tee pipe can be sprayed onto the fabric cover. When the auxiliary material enters the dispersion filter, the dispersion filter filters and disperses the auxiliary material. Finally, the fabric cover restricts the sprayed fabric area, and the dispersed auxiliary material enters the main material and is fully mixed and synthesized with the main material.
[0006] Furthermore, the feeding unit is a closed auxiliary material storage hopper, which can temporarily store auxiliary materials and wait for the feeding rotary valve to feed them.
[0007] Furthermore, a metering rotary valve is connected to the bottom of the auxiliary material storage hopper. The bottom of the metering rotary valve is connected to the buffer hopper via a flange, and the bottom of the buffer hopper is connected to the top of the feeding rotary valve. The metering rotary valve can complete the single feeding amount of auxiliary material. At this time, the feeding rotary valve only serves as the auxiliary material feeding time and feeding rate. The feeding rotary valve can feed all the auxiliary materials received by the buffer hopper into the production vessel.
[0008] Furthermore, the top of the auxiliary material storage hopper is provided with a feeding receiving flange; the feeding receiving flange is connected to the discharge port of the pneumatic conveying equipment; the pneumatic output equipment can transfer the low-level auxiliary material to the top of the auxiliary material storage hopper, and feed it into the feeding receiving flange by vacuum discharge, so that the auxiliary material is stored in the auxiliary material storage hopper.
[0009] Furthermore, the diameter of the middle end of the oblique tee is smaller than the diameters of the other two ends.
[0010] Furthermore, the pressure gas source can be a raw material gas source, a pressure nitrogen source, or a pressure pure air source. Raw material gas sources include hydrogen and carbon monoxide, which serve as both the power source for injecting auxiliary materials and the raw material source for the reaction of main and auxiliary materials, and can directly participate in the synthesis reaction. Pressure nitrogen or pressure pure air sources serve only as the power source for injecting auxiliary materials and do not interfere with the material synthesis reaction in the production vessel.
[0011] Furthermore, the bottom of the oblique tee pipe is connected to a bend pipe via a flange; the bend pipe is connected to the manhole of the production vessel via a flange; since the manhole is located on the side of the vessel cover, the oblique tee pipe and the production vessel are matched by the bend pipe, so that the oblique tee pipe can maintain a vertical state, and the auxiliary material inside the bend pipe can be sprayed into the inside of the production vessel by a pressurized air source.
[0012] Furthermore, the inclined tee is also connected to an exhaust pipe; the exhaust pipe is connected to a filter via a flange, and the filter is connected to an exhaust valve; after the auxiliary materials are added, to avoid excessive pressure inside the production vessel, the exhaust valve is opened to release the pressurized gas entering the production vessel. During the release, the filter traps any powder that has escaped from the auxiliary materials or main materials; when the pressurized gas source sprays into the production vessel again, the airflow is used to reintroduce the powder trapped by the filter into the main materials.
[0013] Compared with existing technologies, the auxiliary material feeding device of this utility model can precisely control the auxiliary material feeding time, feeding amount, and feeding rate by controlling the start and stop time, start and stop frequency, and rotation number within the start and stop time of the feeding rotary valve. The auxiliary material is fed into the distributor through the inclined three-way pipe, and the auxiliary material is sprayed through the distribution hood with the help of a pressurized air source. The auxiliary material is filtered and fully dispersed by the dispersion filter at the bottom of the inner side of the distribution hood. The dispersed auxiliary material is distributed into the reactor along the distribution hood, and the distribution hood constrains the diffusion surface of the auxiliary material to prevent it from being sprayed onto the inner wall of the reactor on top of the main material. When the pressurized air source sprays the auxiliary material, it can prevent the powder from staying on the inclined three-way pipe and the inner wall of the distribution hood, ensuring that the total amount of auxiliary material metered is consistent with the total amount added. The pressurized air source can directly use the raw material gas source participating in the reaction, such as hydrogen and carbon monoxide; or it can directly use the gas source used for pneumatic transmission, such as nitrogen and pure air, which can enable the auxiliary material to fully contact and synthesize with the main material.

[0019] Example 1: like Figure 1 The auxiliary material feeding equipment shown includes: The controller for the entire production reactor; The oblique tee pipe 1 has a threaded pipe 2 integrally formed at the bottom, and the bottom of the oblique tee pipe 1 is connected to the manhole or auxiliary material inlet of the production vessel 3 through a flange; Feeding rotary valve 4, the bottom of which is fixed to the top of the inclined tee pipe 1 via a flange; the top of the feeding rotary valve 4 is connected to a feeding unit via a flange. The jetting pipeline 5 is connected to the pressure gas source via a pressure regulating valve 6. The material distributor includes a material cover 7 disposed inside the production vessel 3 and screwed to a threaded tube 2. The lower inner side of the material cover 7 is integrally formed with multiple retaining rings 8. A threaded groove is provided below the retaining rings 8. A pressure tube seat 9 is screwed onto the threaded groove. A dispersion filter screen 10 is disposed between the pressure tube seat 9 and the retaining rings 8.
[0020] When the auxiliary material is fed, it enters the feeding rotary valve 4 and is metered by rotating the valve. The metered auxiliary material is then fed to the bottom of the feeding rotary valve 4 and then into the inclined three-way pipe 1. Pressure air is then sprayed into the spraying pipeline 5 through the pressure air source and the pressure regulating valve 6, so that the auxiliary material in the inclined three-way pipe 1 can be sprayed onto the fabric cover 7. When the auxiliary material enters the dispersion filter 10, the dispersion filter 10 filters and disperses the auxiliary material. Finally, the fabric cover 7 restricts the spraying area, and the dispersed auxiliary material enters the main material and is fully mixed and synthesized with the main material.
[0021] Example 2: like Figure 2 The auxiliary material feeding device shown has a closed auxiliary material storage hopper 11 as the feeding unit. The auxiliary material storage hopper 11 can temporarily store auxiliary materials and wait for the feeding rotary valve 4 to feed them.
[0022] The bottom of the auxiliary material storage hopper 11 is also connected to a metering rotary valve 12. The bottom of the metering rotary valve 12 is connected to the buffer hopper 13 through a flange. The bottom of the buffer hopper 13 is connected to the top of the feeding rotary valve 4. The metering rotary valve 12 can complete the single addition of auxiliary materials. At this time, the feeding rotary valve 4 only serves as the time and acceleration rate for adding auxiliary materials. The feeding rotary valve 4 can put all the auxiliary materials received by the buffer hopper 13 into the production vessel 3.
[0023] The top of the auxiliary material storage hopper 11 is provided with a feeding receiving flange 14; the feeding receiving flange 14 is connected to the discharge port of the pneumatic conveying equipment; the pneumatic output equipment can transfer the low-level auxiliary material to the top of the auxiliary material storage hopper 11, and send it into the feeding receiving flange 14 by vacuum discharge, and the auxiliary material is stored in the auxiliary material storage hopper.
[0024] The diameter of the middle end of the oblique tee pipe 1 is smaller than the diameters of the other two ends.
[0025] The pressure gas source can be a raw material gas source, a pressure nitrogen source, or a pressure pure air source. Raw material gas sources include hydrogen and carbon monoxide. These gases serve as both the power source for injecting auxiliary materials and the raw material source for the reaction of main materials and auxiliary materials, and can directly participate in the synthesis reaction. Pressure nitrogen or pressure pure air sources only serve as the power source for injecting auxiliary materials and do not interfere with the material synthesis reaction inside the production vessel 3.
[0026] like Figure 3 As shown, the bottom of the oblique tee pipe 1 is connected to a bend pipe 15 via a flange; the bend pipe 15 is connected to the manhole of the production vessel 3 via a flange; since the manhole is located on the side of the vessel cover, the oblique tee pipe 1 and the production vessel 3 are matched by the bend pipe 15, so that the oblique tee pipe 1 can maintain a vertical state, and the auxiliary material in the bend pipe 15 can be sprayed into the inside of the production vessel 3 by a pressurized air source.
[0027] Example 3: like Figure 4 The auxiliary material feeding device shown has an exhaust pipe 16 connected to the inclined tee pipe 1; the exhaust pipe 16 is connected to a filter 17 via a flange, and the filter 17 is connected to an exhaust valve 18; after the auxiliary material is added, to avoid excessive pressure inside the production vessel 3, the exhaust valve 18 is opened to discharge the pressurized air entering the production vessel 3. During discharge, the filter 17 intercepts the powder that escapes from the auxiliary material or main material; when the pressurized air source sprays into the production vessel 3 again, the airflow is used to re-inject the powder intercepted by the filter 17 into the main material.
