Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a reaction vessel with a quantitative feeding structure. Background Technology

[0002] In the chemical industry, physical or chemical reactions are required during product manufacturing, and reaction vessels are generally used as containers. Reaction vessels are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries as pressure vessels to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation. Reaction vessels are typically large in volume, and the volume of raw materials to be fed is usually in a specific ratio. To facilitate the addition of raw materials to the reaction vessel, a feeding structure is usually installed to quantitatively feed the materials into the reaction vessel.

[0003] However, the existing quantitative feeding structure of the reactor is not convenient for weighing and calibrating the material introduced into the reactor during use. If the material is lost or left behind during the feeding process, it will easily lead to a reduction in the amount of material, which is not conducive to accurate feeding. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose a reaction vessel with a quantitative feeding structure to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides a reaction vessel with a quantitative feeding structure, comprising a reaction vessel for processing materials, a feeding hopper fixedly installed at the top of the reaction vessel, a quantitative silo for weighing materials fixedly installed at one end of the feeding hopper, a feeding baffle fixedly installed at the bottom of the quantitative silo to seal it, the feeding baffle being signal-connected to a main control unit for automated control, the main control unit being signal-connected to a sealing baffle for sealing the quantitative silo, a regulating air pump for adjusting the internal air pressure of the quantitative silo being provided above the sealing baffle, a pressure detection frame for carrying materials fixedly installed at the bottom of the quantitative silo, and a pressure baffle for pressure protection fixedly installed inside the pressure detection frame.

[0006] Preferably, in any of the above embodiments, the feeding hopper is configured as an arc-shaped structure, the quantitative silo is fixedly installed at the top of the reactor, and the bottom of the quantitative silo has a feeding outlet connected to the feeding hopper.

[0007] The above technical solution provides a stable and safe environment for the reaction of materials in the reactor. The feeding hopper adopts an arc-shaped structure design, which facilitates the smooth flow of materials and reduces blockage and accumulation during the feeding process. The feeding hopper and the quantitative silo ensure that the material has a short and smooth path from feeding to weighing and then into the reactor, reducing the possibility of material loss and residue, and improving feeding efficiency and accuracy. The inner wall of the quantitative silo is made smooth to reduce the adhesion and residue of materials in the silo, ensuring the accuracy of each weighing. At the same time, the quantitative silo provides a reliable guarantee for the quantitative feeding of the reactor.

[0008] Preferably, in any of the above schemes, the feeding baffle includes a feeding electric rod connected to the main control unit and an isolated discharging baffle. The feeding electric rod is fixedly installed inside the quantitative silo, and one end of the feeding electric rod is fixedly installed with the discharging baffle that moves inside the quantitative silo.

[0009] The above technical solution is adopted as follows: Under the control of the main control unit, the feeding electric rod drives the discharge baffle to move up and down inside the quantitative silo. When material weighing is required, the discharge baffle rises under the action of the electric rod, closing the feeding outlet and preventing the material from falling, ensuring that the material does not enter the reactor during the weighing process, thus ensuring the accuracy of the weighing. After the weighing is completed, the feeding electric rod controls the discharge baffle to open the feeding outlet according to the instruction of the main control unit, so that the quantitative material can smoothly enter the reactor, avoiding errors in the weighing process and improving the quantitative accuracy of feeding.

[0010] Preferably, in any of the above embodiments, the sealing baffle includes a sealing motor connected to the main control unit and a feeding plate for sealing. The sealing motor is fixedly installed at the feeding end of the quantitative silo, and the output end of the sealing motor is fixedly installed with the feeding plate that rotates inside the quantitative silo.

[0011] The above technical solution is adopted as follows: Under the control of the main control unit, the sealing motor drives the feeding plate to rotate at the feeding end of the quantitative silo, realizing the opening and closing of the feeding port. Before the material enters the quantitative silo for weighing, the sealing motor controls the feeding plate to rotate to the open position, so as to introduce the material into the quantitative silo. After the material is weighed, the sealing motor drives the feeding plate to rotate again to close the feeding port, so that the regulating air pump can introduce high-pressure gas into the quantitative silo and push the material down. The good sealing performance of the sealing baffle ensures the sealing of the quantitative silo under different working conditions, providing an important guarantee for accurate feeding.

[0012] Preferably, in any of the above schemes, the regulating air pump is signal-connected to the main control unit, and the regulating air pump is fixedly installed inside the quantitative silo.

[0013] The above technical solution is adopted as follows: After the material is weighed in the quantitative silo, the main control unit controls the start of the regulating air pump to inject high-pressure gas into the quantitative silo. The high-pressure gas diffuses rapidly in the silo, generating a downward thrust on the material, enabling the material to overcome gravity and friction and smoothly enter the reactor through the feeding outlet, thereby improving the stability and reliability of the feeding process.

[0014] Preferably, in any of the above embodiments, the pressure detection frame includes a pressure sensor connected to the main control unit and a pressure plate that bears the detection pressure. The pressure sensor is fixedly installed inside the quantitative silo, and the pressure plate is fixedly installed at the detection end of the pressure sensor.

[0015] The above technical solution works as follows: When material enters the quantitative silo and falls onto the pressure baffle, the pressure plate converts the weight of the material transmitted by the pressure baffle into a pressure signal, which is then transmitted to the pressure sensor. The pressure sensor converts the received pressure signal into an electrical signal and transmits it to the main control unit. The main control unit calculates the actual weight of the material based on a preset algorithm and parameters such as material density, and compares it with the set target weight. If there is a deviation in weight, the main control unit can adjust the state of the feeding baffle and the sealing baffle in a timely manner, or take other corresponding measures to ensure that the amount of material entering the quantitative silo each time meets the accuracy requirements, thereby achieving high-precision quantitative feeding.

[0016] Preferably, in any of the above embodiments, the pressure baffle includes a material support base for supporting the material, a positioning electric rod for signal connection to the main control unit, and a locking block for locking and fixing. The material support base is fixedly installed on the top of the pressure plate, and the positioning electric rod is fixedly installed inside the material support base. One end of the positioning electric rod is fixedly installed with a locking block that moves inside the support base.

[0017] The above technical solution provides a stable platform for the material support, ensuring uniform distribution of the material within the hopper and facilitating accurate weight measurement. Under the control of the main control unit, the positioning electric rod drives the locking block to extend and retract within the material support. After weighing, the locking block extends and engages with the inner wall of the quantitative hopper, firmly fixing the pressure baffle inside the hopper and preventing damage to the pressure detection frame from high-pressure gas. When weighing is required, the positioning electric rod controls the locking block to retract, releasing the pressure baffle from the hopper wall and ensuring accurate transmission of the material's weight to the pressure detection frame, thus improving the efficiency and reliability of the entire quantitative feeding process.

[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0019] 1. Connect a quantitative hopper for weighing and calibrating materials to the feeding hopper of the reactor. The material entering the quantitative hopper is detected by the pressure detection frame inside the quantitative hopper, and the feeding baffle and sealing baffle are opened and closed according to the detected weight. The material to be added is subjected to closed quantitative weighing and calibration. After the material is quantitatively calibrated, the material is forced into the reactor by adjusting the high pressure provided by the air pump. This avoids material loss or residue during the feeding process, which may cause feeding deviation and improves the quantitative accuracy of feeding.

[0020] 2. A pressure baffle is installed at the top of the pressure testing frame that can engage with the quantitative material hopper. The pressure baffle supports the quantitative material and can control the engagement between the pressure baffle and the quantitative material hopper to reduce the impact of high pressure on the pressure testing frame, which helps to ensure the accuracy of material quantification.

[0031] Preferably, of any of the above schemes, the feeding hopper 2 is configured as an arc-shaped structure, the quantitative silo 4 is fixedly installed at the top of the reactor 1, and the bottom of the quantitative silo 4 is provided with a feeding outlet that is connected to the feeding hopper 2.

[0032] The above technical solution is adopted as follows: the reactor 1 provides a stable and safe environment for the reaction of materials. The feeding hopper 2 adopts an arc-shaped structure design, which is conducive to the smooth flow of materials and reduces the blockage and accumulation of materials during the feeding process. The feeding hopper 2 and the quantitative silo 4 ensure that the material has a short and smooth path from feeding to weighing and then to entering the reactor 1, reducing the possibility of material loss and residue, and improving feeding efficiency and accuracy. The inner wall of the quantitative silo 4 is made smooth to reduce the adhesion and residue of materials in the silo and ensure the accuracy of each weighing. At the same time, the quantitative silo 4 provides a reliable guarantee for the quantitative feeding of the reactor.

[0033] Preferably, in any of the above schemes, the feeding baffle 5 includes a feeding electric rod 51 connected to the main control unit and a discharge baffle 52 for isolation. The feeding electric rod 51 is fixedly installed inside the quantitative silo 4, and one end of the feeding electric rod 51 is fixedly installed with the discharge baffle 52 that moves inside the quantitative silo 4.

[0034] The above technical solution is adopted as follows: Under the control of the main control unit, the feeding electric rod 51 drives the discharge baffle 52 to move up and down inside the quantitative silo 4. When material weighing is required, the discharge baffle 52 rises under the action of the electric rod, closes the feeding outlet, prevents the material from falling, and ensures that the material will not enter the reactor 1 during the weighing process, thus ensuring the accuracy of the weighing. After the weighing is completed, the feeding electric rod 51 controls the discharge baffle 52 to open the feeding outlet according to the instruction of the main control unit, so that the quantitative material can smoothly enter the reactor 1, avoid the error of the material during the weighing process, and improve the quantitative accuracy of feeding.

[0035] Preferably, the sealing baffle 6 includes a sealing motor 61 connected to the main control unit and a feeding plate 62 for sealing. The sealing motor 61 is fixedly installed at the feeding end of the quantitative silo 4, and the feeding plate 62, which rotates inside the quantitative silo 4, is fixedly installed at the output end of the sealing motor 61.

[0036] The above technical solution is adopted: Under the control of the main control unit, the sealing motor 61 drives the feeding plate 62 to rotate at the feeding end of the quantitative silo 4 to realize the opening and closing of the feeding port. Before the material enters the quantitative silo 4 for weighing, the sealing motor 61 controls the feeding plate 62 to rotate to the open position to introduce the material into the quantitative silo 4. After the material is weighed, the sealing motor 61 drives the feeding plate 62 to rotate again to close the feeding port, so that the regulating air pump 7 can introduce high-pressure gas into the quantitative silo 4 to push the material down. The good sealing performance of the sealing baffle 6 ensures the sealing of the quantitative silo 4 under different working conditions, providing an important guarantee for accurate feeding.

[0037] Preferably, of any of the above schemes, the regulating air pump 7 is connected to the main control unit via signal, and the regulating air pump 7 is fixedly installed inside the quantitative silo 4.

[0038] The above technical solution is adopted: after the material is weighed in the quantitative silo 4, the main control unit controls the start of the regulating air pump 7 to inject high-pressure gas into the quantitative silo 4. The high-pressure gas diffuses rapidly in the silo, generating a downward thrust on the material, enabling the material to overcome gravity and friction and smoothly enter the reactor 1 through the feeding outlet, thereby improving the stability and reliability of the feeding process.

[0039] Preferably, in any of the above schemes, the pressure detection frame 8 includes a pressure sensor 81 connected to the main control unit and a pressure plate 82 that bears the detection pressure. The pressure sensor 81 is fixedly installed inside the quantitative silo 4, and the pressure plate 82 is fixedly installed on the detection end of the pressure sensor 81.

[0040] The above technical solution is adopted as follows: When the material enters the quantitative silo 4 and falls on the pressure baffle 9, the pressure plate 82 converts the weight of the material transmitted by the pressure baffle 9 into a pressure signal and transmits it to the pressure sensor 81. The pressure sensor 81 converts the received pressure signal into an electrical signal and transmits it to the main control unit. The main control unit calculates the actual weight of the material according to the preset algorithm and parameters such as material density, and compares it with the set target weight. If there is a deviation in weight, the main control unit can adjust the state of the feeding baffle 5 and the sealing baffle 6 in time, or take other corresponding measures to ensure that the amount of material entering the quantitative silo 4 each time meets the accuracy requirements, thereby achieving high-precision quantitative feeding.

[0041] Preferably, in any of the above embodiments, the pressure baffle 9 includes a material support seat 91 for supporting the material, a positioning electric rod 92 for signal connection to the main control unit, and a locking block 93 for locking and fixing. The material support seat 91 is fixedly installed on the top of the pressure plate 82. The positioning electric rod 92 is fixedly installed inside the material support seat 91. One end of the positioning electric rod 92 is fixedly installed with a locking block 93 that moves inside the support seat 91.

[0042] The above technical solution provides a stable platform for the material support 91, ensuring uniform distribution of the material within the hopper and facilitating accurate weight measurement. Under the control of the main control unit, the positioning electric rod 92 drives the locking block 93 to extend and retract within the material support 91. After weighing, the locking block 93 extends and engages with the inner wall of the quantitative hopper 4, firmly fixing the pressure baffle 9 within the hopper and preventing damage to the pressure detection frame 8 from high-pressure gas. When weighing is required, the positioning electric rod 92 controls the locking block 93 to retract, releasing the engagement between the pressure baffle 9 and the hopper wall, allowing the weight of the material to be accurately transmitted to the pressure detection frame 8, thus improving the efficiency and reliability of the entire quantitative feeding process.

[0043] The working principle of the reaction vessel with a quantitative feeding structure of this utility model is as follows:

[0044] During feeding, the material is introduced into the quantitative silo 4 through the feeding conveyor structure. The main control unit controls the feeding electric rod 51 to lower the discharge baffle 52 to close the feeding outlet. The material falls onto the pressure plate 82. The pressure sensor 81 detects the pressure and transmits it to the main control unit to calculate the weight. If the weight does not reach the set value, feeding continues. After reaching the set value, the sealing motor 61 drives the feeding plate 62 to close the feeding port. Then, the main control unit starts the regulating air pump 7 to inject high-pressure gas into the quantitative silo 4. At the same time, it controls the positioning electric rod 92 to make the locking block 93 lock into the interior of the quantitative silo 4, opening the discharge baffle 52. The material enters the reactor 1 through the feeding hopper 2 under the gas thrust.

[0045] Compared with the prior art, the present invention has the following advantages:

[0046] 1. A quantitative hopper 4 for weighing and calibrating materials is connected to the feeding hopper 2 of the reactor 1. The material entering the quantitative hopper 4 is detected by the pressure detection frame 8 inside the quantitative hopper 4. The feeding baffle 5 and the sealing baffle 6 are opened and closed according to the detected weight. The material to be added is subjected to closed quantitative weighing and calibration. After the material is quantitatively calibrated, the material is pressed into the reactor 1 by adjusting the high pressure provided by the air pump 7. This avoids the loss or residue of material during the feeding process, which may cause feeding deviation and improves the quantitative accuracy of feeding.

[0047] 2. A pressure baffle 9 is installed at the top of the pressure testing frame 8, which can engage with the quantitative material bin 4. The pressure baffle 9 supports the quantitative material and can control the engagement between the pressure baffle 9 and the quantitative material bin 4 to reduce the impact of high pressure on the pressure testing frame 8, which helps to ensure the accuracy of material quantitative measurement.
