Description

Technical Field

[0001] This utility model relates to the field of organic chemical raw materials, and specifically discloses an additive device for the production of organic chemical raw materials. Background Technology

[0002] Organic chemical raw materials refer to various organic materials used in the manufacture of organic compounds or organic chemical products. These raw materials can originate from nature or be prepared artificially. Organic chemical raw materials have wide applications in organic chemical synthesis and pharmaceutical synthesis, serving as essential basic substances for the manufacture of various chemicals and materials. In the industrial production of organic chemical raw materials, the precise quantitative addition of raw materials is a core element determining the controllability of the reaction process, the stability of product quality, and the safety of the process. Especially for multi-component synergistic reaction systems (such as copolymerization reactions and catalytic synthesis), it is necessary to achieve quantitative addition and dynamic flow control of multiple raw materials to avoid problems such as increased side reactions and product isomerization caused by deviations in the timing of material addition or errors in the proportioning.

[0003] Currently available traditional raw material addition devices, for processes that require the simultaneous addition of multiple raw materials, typically equip each feeding tank with an independent manual valve or a simple solenoid valve. Operators need to adjust the opening degree of each valve individually. In order to ensure accurate feeding, weighing equipment is required to weigh multiple raw materials sequentially before feeding. This increases the process flow and costs. Furthermore, the feeding amount and start / stop points require manual monitoring and intervention, which is not only inefficient but also prone to batch-to-batch quality fluctuations due to operational errors. It is difficult to adapt to the needs of continuous and large-scale production. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0024] Please see Figure 1-6An additive device for the production of organic chemical raw materials includes a feeding mechanism. The feeding mechanism includes two symmetrically distributed side plates 1. A support plate 2 and a fixing plate 6 are fixedly installed between the two side plates 1 from top to bottom. Multiple linearly arranged feeding tanks 3 are fixedly installed through the top of the support plate 2. The bottom of the feeding tanks 3 is connected to a discharge pipe 4. The outer side wall of the discharge pipe 4 has symmetrically distributed ports 401. The interior of the multiple ports 401 is slidably connected to a first material blocking plate 5. The top of the first material blocking plate 5 has a first discharge hole 501 located inside the multiple discharge pipes 4 and matching the discharge pipes 4.

[0025] A metering tank 601 is fixedly connected to the top of the fixed plate 6 through a flange and connected to the corresponding discharge pipe 4. The bottom of the metering tank 601 is connected to the discharge pipe 602. The outer side wall of the discharge pipe 602 is provided with symmetrically distributed through holes 603. The interior of the multiple through holes 603 is slidably connected to a second material blocking plate 7. The top of the second material blocking plate 7 is provided with a second discharge hole 701 located inside the multiple discharge pipes 602 and matching the discharge pipes 602. The bottom of the discharge pipe 602 is connected to a connecting pipe 8. The other end of the multiple connecting pipes 8 is connected to a feeding pipe 801.

[0026] In this embodiment: during feeding, the first baffle plate 5 is closed and the second baffle plate 7 is open in the initial state, the metering tank 601 is emptied, the motor 101 is started, the second baffle plate 7 closes to trap the metering tank 601, and at the same time the first baffle plate 5 opens, the feeding tank 3 fills the metering tank 601 with raw materials. After filling is completed, the motor 101 reverses, the first baffle plate 5 closes to stop feeding, the second baffle plate 7 opens, and the raw materials in the metering tank 601 are discharged to the reaction equipment through the connecting pipe 8 and the feeding pipe 801. This realizes the simultaneous quantitative addition of multiple raw materials in a single operation, simplifies the process flow, and improves the mixing uniformity and reaction efficiency.

[0027] As a technical optimization of this utility model, a driving mechanism for moving the first material blocking plate 5 and the second material blocking plate 7 is provided at the front end of one of the side plates 1. The driving mechanism includes a motor 101 fixedly installed at the rear end of the side plate 1 via a base. The output end of the motor 101 passes through the side plate 1 and is fixedly connected to a gear 104. Two symmetrically distributed racks 105 are meshed on the outer wall of the gear 104. The first material blocking plate 5 and the second material blocking plate 7 are fixedly connected to the two racks 105 respectively.

[0028] In this embodiment: After the motor 101 starts, its output shaft drives the gear 104 to rotate. Since the gear 104 meshes with two symmetrically distributed racks 105, the rotation of the gear 104 will drive the two racks 105 to move synchronously in opposite directions. The first baffle plate 5 is fixed to one of the racks 105. As the rack 105 moves, it drives the first discharge hole 501 to align or misalign with the discharge pipe 4, thereby controlling the opening and closing of the feeding tank 3 to discharge into the metering tank 601. The second baffle plate 7 is fixed to the other rack 105 and moves synchronously in the opposite direction, controlling the alignment or misalignment of the second discharge hole 701 with the discharge pipe 602, thereby realizing the discharge control of the raw materials in the metering tank 601.

[0029] As a technical optimization of this utility model, a T-shaped sliding groove 102 is provided behind the rack 105 on the outer wall of the side plate 1, and a T-shaped slider 103 that is adapted to it and fixedly connected to the rack 105 is slidably connected inside the sliding groove 102.

[0030] In this embodiment, the rack 105 slides within the T-shaped groove 102 of the side plate 1 via the T-shaped slider 103. The T-shaped structure of the groove 102 restricts the movement direction of the slider 103, ensuring that the rack 105 can only move horizontally along a straight line, avoiding deviation or tilting.

[0031] As a technical optimization of this utility model, the motor 101 is a servo motor, and the front end of the side plate 1 is provided with a PLC controller 106 electrically connected to the motor 101. The PLC controller 106 is used to adjust the movement stroke of the first material blocking plate 5 and the second material blocking plate 7.

[0032] In this embodiment: the servo motor receives pulse signals from the PLC controller 106 and precisely controls the rotation angle and speed of the output shaft, thereby adjusting the travel of the rack 105. That is, the PLC controller 106 presets the rotation angle of the motor 101 so that the opening time of the first blocking plate 5 matches the feeding amount of the feeding tank 3, ensuring that the filling amount of the metering tank 601 is consistent each time, and simultaneously adjusting the closing position of the second blocking plate 7 to avoid residual raw materials in the metering tank 601 and ensure complete discharge.

[0033] As a technical optimization of this utility model, the top of the feeding tank 3 is provided with a sealed top cover 301, and the metering tank 601 is a transparent structure.

[0034] In this embodiment: the sealed top cover 301 seals the top of the feeding tank 3 to prevent external dust, moisture and other contaminants from entering, ensuring the purity of the raw materials. The operator can directly observe the amount of raw materials in the quantitative tank 601 (made of modified transparent polypropylene (PP)) through the transparent tank body.

[0035] As a technical optimization of this utility model, the first material blocking plate 5 and the second material blocking plate 7 are made of polypropylene or polytetrafluoroethylene, and the inner wall of the port 401 and the inner wall of the through hole 603 are provided with elastic sealing strips.

[0036] In this embodiment, the first and second material blocking plates 5 and 7, made of polypropylene (PP) or polytetrafluoroethylene (PTFE), can withstand corrosive raw materials such as organic solvents, strong acids, and strong alkalis, thus extending the service life of the device. The elastic sealing strips (such as silicone or fluororubber) on the inner walls of the port 401 and the through hole 603 are tightly fitted to the first and second material blocking plates 5 and 7, and remain sealed during the movement of the first and second material blocking plates 5 and 7 to prevent raw material leakage.

[0037] The working principle and usage process of this utility model are as follows: In this device, the number of feeding tanks 3 can be set according to the type of raw material added, and the volume of each metering tank 601 can be customized. The volume of the metering tank 601 is customized according to the amount of raw material added (the volume of the metering tank 601 is variable, but the height is inconvenient). The feeding pipe 801 is connected to the feed pipe of the reaction equipment. The operating parameters of the motor 101 are set on the PLC controller 106. In use, the sealed top cover 301 is opened, and the organic chemical raw materials are added into the interior of each feeding tank 3 respectively. In the initial state, the first blocking plate 5 is closed, the second blocking plate 7 is open, the metering tank 601 is emptied, the motor 101 is started, the second blocking plate 7 closes to trap the metering tank 601, and at the same time the first blocking plate 5 opens, the feeding tank 3 fills the metering tank 601 with raw materials. After filling is completed, the motor 101 reverses, the first blocking plate 5 closes to stop feeding, the second blocking plate 7 opens, and the raw materials in the metering tank 601 are discharged to the reaction equipment through the connecting pipe 8 and the feeding pipe 801. The PLC controller 106 cycles the above actions according to the preset program to achieve precise feeding in multiple batches.
