Description

Technical Field

[0001] The present invention belongs to the technical field of chemical equipment, and mainly relates to an efficient and safe solid particle feeding system. Background Art

[0002] In many industrial fields, such as chemical industry, pharmaceutical, food, building materials, etc., the handling and transportation of solid particle materials are important links in the production process. For example, in chemical production, various solid catalysts, raw material particles, etc. need to be accurately added to the reaction kettle to ensure the smooth progress of chemical reactions and the stability of product quality; in the pharmaceutical industry, drug particles need to be accurately metered and added to the preparation equipment to make various drug dosage forms; in food processing, the quantitative addition of solid particles such as grains and sugar particles is crucial for controlling the taste, nutritional components, etc. of products.

[0003] The traditional manual feeding method is not only inefficient, but also difficult to ensure the safety, accuracy and uniformity of feeding, easily leading to product quality fluctuations and causing production accidents. Therefore, there is an urgent need for a device that can achieve automatic and precise feeding. Summary of the Invention

[0004] The present invention provides an efficient and safe solid particle feeding system to solve the problems of low efficiency and inaccuracy of manual feeding in the prior art.

[0005] To solve the above problems, the present invention adopts the following technical solutions: An efficient and safe solid particle feeding system includes a control mechanism, a feeding mechanism, and a metering mechanism connected to the feeding mechanism. The metering mechanism is used to put the metered materials into the reaction kettle; The feeding mechanism includes a feeding bin and a screw feeder assembled on the feeding bin. The feeding bin is used to hold the materials to be added, and the materials fall into the screw feeder, and the screw feeder transports the materials to move; The metering mechanism includes a weighing unit and a metering bin assembled on the weighing unit. The metering bin is connected to the screw feeder so that the screw feeder transports the materials into the metering bin, and the weighing unit is used to weigh the weight of the materials in the metering bin; The control mechanism is electrically connected to the screw feeder and the weighing unit respectively. The weighing unit feeds back the weight data of the materials to the control mechanism, and the control mechanism controls the operation of the screw feeder according to the weight data of the materials.

[0006] It has the following beneficial effects: The control mechanism accurately controls the screw feeder through the feedback of the weighing unit, and then controls the weight of the materials entering the metering bin, avoiding the inaccuracy of manual feeding. Compared with manual feeding, it reduces the labor cost and operation risk, improves the feeding efficiency, and further improves the product quality.

[0007] Furthermore, it also includes a gas replacement mechanism which is respectively connected to the feeding bin, the screw feeder and the metering bin to replace the air inside with inert gas.

[0008] It has the following beneficial effects: The chemical properties of inert gas are inactive and it is not easy to chemically react with other substances under normal temperature and pressure. Many substances are prone to oxidation reactions with oxygen in the air. For example, metals are easily oxidized and rusted during processing and storage. However, by using inert gas to replace the air and form an inert gas protection atmosphere, oxygen can be effectively isolated, preventing metal oxidation and extending the service life of metal products. In the food industry, oil-based foods are prone to oxidative rancidity. Inert gas protection can slow down the oxidation rate of oils and fats, maintain the flavor and quality of foods, and extend the shelf life. In some environments with flammable and explosive substances, oxygen in the air may trigger combustion or explosion accidents. For example, in the petrochemical industry, in equipment such as oil tanks and reaction kettles, using inert gas to replace the air inside and reduce the oxygen content can keep the environment in a non-flammable and non-explosive state, eliminate explosion hazards, and ensure production safety.

[0009] Furthermore, the feeding bin, the screw feeder and the metering bin are connected with an exhaust mechanism which is used for exhausting the gas inside the feeding bin, the screw feeder and the metering bin.

[0010] It has the following beneficial effects: When carrying out inert gas replacement, it is necessary to exhaust the original air and other gases in the equipment or space to allow the inert gas to fully fill. Arranging the exhaust mechanism can provide a directional exhaust channel, enabling the air to be exhausted more quickly and smoothly, thereby improving the efficiency of inert gas replacement, shortening the replacement time required, ensuring the required inert gas concentration can be achieved within a short time, and realizing an effective protection atmosphere. A reasonably arranged exhaust mechanism helps the inert gas to be evenly distributed in the equipment or space. Without an exhaust mechanism, the gas flow may be disordered, resulting in difficulty for the inert gas to reach some areas, while there may be air residues in some areas, making it impossible to achieve a comprehensive and uniform replacement. By setting multiple exhaust points or a suitable exhaust layout, the inert gas can be advanced more evenly during the replacement process, exhausting the air from every corner and ensuring the consistency of the inert gas concentration throughout the space. During the process of filling inert gas, without an exhaust mechanism, as the inert gas is continuously filled, the pressure inside the equipment or space will continuously increase, possibly exceeding the design pressure of the equipment, leading to equipment damage or even serious safety accidents such as explosions. The exhaust mechanism can timely exhaust the excess gas when the pressure rises, maintaining the system pressure within a safe range and protecting the safety of the equipment and personnel. In some cases, the displaced gas may be a harmful gas or a flammable and explosive gas. If these gases cannot be discharged in time and accumulate in the equipment or space, it may pose a hazard to the health of the operators, or trigger dangers such as explosion and fire when encountering conditions such as a fire source. The exhaust mechanism can discharge these harmful gases to a safe area, reducing the safety risk; The exhaust mechanism can be an important position for gas monitoring. During the replacement process, gas detection instruments can be set at the exhaust port to continuously monitor the composition and concentration of the discharged gas, so as to judge the progress and effect of the inert gas replacement. For example, by detecting the oxygen content in the exhaust, when the oxygen content drops to a certain level, it can be considered that the replacement has achieved the expected goal.

[0011] Further, the inert gas is nitrogen.

[0012] It has the following beneficial effects: Nitrogen is a colorless, odorless, and tasteless gas under normal temperature and pressure. The human senses such as vision and smell cannot directly perceive its existence; The nitrogen molecule is composed of two nitrogen atoms bonded by a covalent triple bond, and its molecular structure is very stable. Under normal temperature and pressure, nitrogen is very difficult to chemically react with other substances. Only under special conditions such as high temperature, high pressure, and electric discharge, will it react with certain substances; Nitrogen is the most abundant gas in the Earth's atmosphere, accounting for about 78% of the total volume of the atmosphere. This makes the source of nitrogen very extensive, providing convenient conditions for its large-scale industrial application and acquisition.

[0013] Further, the spiral feeder and the metering bin are connected by a flexible tube, so that the material enters the metering bin through the flexible tube.

[0014] It has the following beneficial effects: The flexible tube has good flexibility and can bend freely within a certain range to adapt to various complex installation environments and spatial layouts. For example, in some pipeline systems that need to bypass obstacles or be laid in narrow spaces, the flexible tube can easily be bent into the required shape without the need for a large amount of cutting and splicing like a rigid pipeline; The flexible tube has a certain degree of twistability and can withstand torsional forces to a certain extent without cracking or damage. This gives it unique advantages in some occasions where the pipeline needs to perform torsional movements, such as oil pipes and gas pipes in mechanical transmission systems; The flexible tube can effectively absorb and buffer vibration energy, reducing the transmission of vibration in the pipeline system. In some equipment or systems with large vibrations, such as the cooling pipeline of an engine and the gas transmission pipeline of a compressor, using a flexible tube can reduce the impact of vibration on the pipeline, improve the stability and reliability of the pipeline system, and extend the service life of the pipeline; The flexible pipe is made of corrosion-resistant materials such as stainless steel, copper alloy, various engineering plastics, etc., and can resist the erosion of chemical substances such as acids, alkalis, and salts. This enables the flexible pipe to be widely used in the fields of chemical industry, petroleum, water treatment, etc. for the transportation of corrosive media, ensuring that the pipeline will not leak or be damaged due to corrosion during long-term use. The flexible pipe adopts a special sealing structure and materials, which can ensure that the pipeline still has good sealing performance under conditions such as bending and twisting, preventing the leakage of the medium. This is crucial for some occasions with high sealing requirements, such as gas transportation and chemical fluid transportation, ensuring the safe operation of the pipeline system and avoiding safety accidents and environmental pollution caused by leakage.

[0015] Furthermore, a first electric valve is provided at the inlet of the metering bin. The flexible pipe is connected to the metering bin through the first electric valve. The first electric valve is wirelessly connected to a remote control component, and the remote control component controls the opening and closing of the first electric valve.

[0016] It has the following beneficial effects: By controlling the first electric valve through the remote control component, remote control and automatic adjustment are achieved, eliminating the need for manual on-site operation, greatly improving the automation level and work efficiency of the production process, and reducing labor costs and operation risks.

[0017] Furthermore, a second electric valve is provided between the metering bin and the reaction kettle. The remote control component is wirelessly connected to the second electric valve to control the opening and closing of the second electric valve.

[0018] It has the following beneficial effects: By controlling the second electric valve through the remote control component, remote control and automatic adjustment are achieved, eliminating the need for manual on-site operation, greatly improving the automation level and work efficiency of the production process, and reducing labor costs and operation risks.

[0019] Furthermore, a temperature control unit is provided on the feeding bin, and the temperature control unit is used to control the temperature inside the feeding bin.

[0020] It has the following beneficial effects: The temperature control unit is a component that can automatically control the temperature, used to monitor the temperature of the equipment or environment in real time and keep the temperature near the target temperature.

[0021] Furthermore, the temperature control unit includes a current controller, and the current controller is used to control the magnitude of the current of the temperature control unit.

[0022] It has the following beneficial effects: The current controller can accurately control the current near the set value to meet the temperature control requirements.

[0023] Furthermore, a stirring paddle is rotationally assembled inside the reaction kettle, and the stirring paddle is used to stir the materials inside the reaction kettle. Brief Description of the Drawings

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are a part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present invention.

[0027] Next, various non-restrictive embodiments of the present invention will be specifically introduced. The number of any element in the drawings is for illustration rather than limitation, and any naming is only for distinction without any restrictive meaning. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0028] As Figure 1 shown, an efficient and safe solid particle feeding system includes a control mechanism, a gas displacement mechanism, a feeding mechanism, and a metering mechanism connected to the feeding mechanism. The metering mechanism is used to put the metered material into the reaction kettle 5, and the material reacts in the reaction kettle 5. In this embodiment, a stirring paddle 11 is rotatably assembled in the reaction kettle 5, and the stirring paddle 11 is used to stir the material in the reaction kettle 5.

[0029] In this embodiment, the feeding mechanism includes a feeding bin 1 and a screw feeder 2 assembled on the feeding bin 1. The feeding bin 1 is used to hold the material to be added, and the material drops into the screw feeder 2, and the screw feeder 2 conveys the material to move.

[0030] In this embodiment, the metering mechanism includes a weighing unit 4 and a metering bin 3 assembled on the weighing unit 4. The metering bin 3 is connected to a screw feeder 2 so that the screw feeder 2 conveys materials into the metering bin 3. The weighing unit 4 is used to weigh the weight of the materials in the metering bin 3, thereby determining the weight of the added materials.

[0031] In this embodiment, the control mechanism is electrically connected to the screw feeder 2 and the weighing unit 4 respectively. The weighing unit 4 feeds back the weight data of the materials to the control mechanism, and the control mechanism controls the operation of the screw feeder 2 according to the weight data of the materials.

[0032] The control mechanism accurately controls the screw feeder 2 through the feedback of the weighing unit 4, and then controls the weight of the materials entering the metering bin, avoiding the inaccuracy of manual feeding. Compared with manual feeding, it reduces labor costs and operation risks, improves the feeding efficiency, and thus improves the product quality.

[0033] In this embodiment, the gas displacement mechanism is connected to the feeding bin 1, the screw feeder 2 and the metering bin 3 respectively to displace the air inside into an inert gas, so that the materials are in an inert gas atmosphere for a long time to prevent the air from reacting with the materials.

[0034] Inert gases are chemically inactive and are not easily chemically reactive with other substances under normal temperature and pressure. Many substances are prone to oxidation reactions with oxygen in the air. For example, metals are easily oxidized and rusted during processing and storage. By using inert gases to displace the air and form an inert gas protection atmosphere, oxygen can be effectively isolated to prevent metal oxidation and extend the service life of metal products. In the food industry, oil-based foods are prone to oxidative rancidity, and inert gas protection can slow down the oxidation rate of oils and fats, maintain the flavor and quality of foods, and extend the shelf life. In some environments with flammable and explosive substances, oxygen in the air may trigger combustion or explosion accidents. For example, in the petrochemical industry, in equipment such as oil tanks and reaction kettles 5, using inert gases to displace the air inside and reduce the oxygen content can make the environment in a non-combustible and non-explosive state, eliminate explosion hazards, and ensure production safety.

[0035] In this embodiment, an exhaust mechanism is connected to the feeding bin 1, the screw feeder 2 and the metering bin 3, and the exhaust mechanism is used to discharge the gases in the feeding bin 1, the screw feeder 2 and the metering bin 3.

[0036] When performing inert gas displacement, it is necessary to discharge the original air and other gases in the equipment or space to allow the inert gas to fill it fully. Arranging an exhaust mechanism can provide a directional exhaust channel, enabling the air to be discharged more quickly and smoothly, thereby improving the efficiency of inert gas displacement, shortening the time required for displacement, ensuring the required inert gas concentration within a short time, and achieving an effective protection atmosphere.

[0037] A reasonably arranged exhaust mechanism helps to evenly distribute inert gas within the equipment or space. Without an exhaust mechanism, the gas flow may become disordered, resulting in difficulty for the inert gas to reach some areas, while there may be air residues in some areas, making it impossible to achieve a comprehensive and uniform replacement. By setting multiple exhaust points or a suitable exhaust layout, the inert gas can advance more evenly during the replacement process, expelling the air from every corner and ensuring the consistency of the inert gas concentration throughout the space.

[0038] During the process of filling inert gas, without an exhaust mechanism, as the inert gas continues to be filled, the pressure within the equipment or space will continuously increase, potentially exceeding the design pressure of the equipment, leading to equipment damage or even serious safety accidents such as explosions. The exhaust mechanism can timely discharge the excess gas when the pressure rises, maintaining the system pressure within a safe range and protecting the safety of the equipment and personnel.

[0039] In some cases, the gas to be replaced may be a harmful gas or a flammable and explosive gas. If these gases cannot be discharged in a timely manner and accumulate within the equipment or space, it may pose a hazard to the health of the operators, or trigger dangers such as explosions and fires when encountering ignition sources, etc. The exhaust mechanism can discharge these harmful gases to a safe area, reducing the safety risks.

[0040] The exhaust mechanism can also serve as an important location for gas monitoring. During the replacement process, gas detection instruments are set at the exhaust port to continuously monitor the composition and concentration of the discharged gas, thereby judging the progress and effect of the inert gas replacement. For example, by detecting the oxygen content in the exhaust, when the oxygen content drops to a certain level, it can be considered that the replacement has achieved the expected goal.

[0048] The flexible pipe 6 has a certain degree of twistability and can withstand torsional forces to a certain extent without cracking or damage, which gives it unique advantages in some occasions where the pipe needs to perform torsional movements, such as oil pipes and gas pipes in mechanical transmission systems.

[0049] The flexible pipe 6 can effectively absorb and buffer vibration energy, reducing the transmission of vibration in the pipe system. In some equipment or systems with large vibrations, such as the cooling pipes of engines and the gas transmission pipes of compressors, using the flexible pipe 6 can reduce the impact of vibration on the pipes, improve the stability and reliability of the pipe system, and extend the service life of the pipes.

[0050] The flexible pipe 6 is made of corrosion-resistant materials such as stainless steel, copper alloy, and various engineering plastics, and can resist the erosion of chemical substances such as acids, alkalis, and salts. This enables the flexible pipe 6 to be widely used in the fields of conveying corrosive media such as chemical industry, petroleum, and water treatment, and can ensure that the pipe will not leak or be damaged due to corrosion during long-term use.

[0051] The flexible pipe 6 adopts a special sealing structure and materials, which can ensure that the pipe still has good sealing performance under conditions such as bending and twisting, preventing medium leakage. This is crucial for some occasions with high sealing requirements, such as gas transmission and chemical fluid transmission, and can ensure the safe operation of the pipe system and avoid safety accidents and environmental pollution caused by leakage.

The current controller 10 can accurately control the current near the set value to meet the temperature control requirements.

[0055] This embodiment is introduced by taking the production of tetrahydrofuran as an example.

[0056] When using Raney nickel catalyst in the production of tetrahydrofuran, the following batching process must be strictly followed: First, inject an appropriate amount of tetrahydrofuran solvent into the reaction kettle 5 to ensure that the ratio of the solvent to the catalyst is 1:3. Subsequently, disassemble and transfer the barreled catalyst to the feeding bin 1, and conduct nitrogen replacement to remove the air inside each component to prevent the catalyst from spontaneously combusting when encountering oxygen.
