Description

TECHNICAL FIELD

[0001] The utility model relates to chemical equipment technical field especially relates to a raw material conveying device. BACKGROUND

[0002] In the field of chemical technology, it is often necessary to carry out complex processing reactions on some materials that have strong irritancy and potential toxicity to the human body. These materials not only have special properties, but also are extremely difficult to handle, and a slight mistake in the operation process can cause serious health hazards to the workers. However, the current reaction kettle design used in the industry has some inherent defects, the most prominent of which is the position setting of the feed inlet. Usually, the feed inlet of the reaction kettle is placed at a high position, and the original design intention of such design may be based on certain process considerations, but it has brought a lot of troubles in actual operation.

[0003] Specifically, since the feed inlet is located at a high position, it is extremely difficult to directly transport these toxic and harmful materials into the reaction kettle through conventional equipment. Not only special conveying devices and techniques are needed, but also the entire conveying process is prone to safety hazards due to the dual factors of height and material properties. In order to solve this problem, some enterprises try to transport the materials in small batches, that is, to divide a large amount of materials into small batches and send them into the reaction kettle one by one by manual or other means. However, this method also faces many challenges. The split transportation not only increases the operation steps and cost, but also each operation step may involve the direct participation of manual work, which undoubtedly greatly increases the risk of the entire processing process.

[0004] More seriously, due to the toxicity and irritancy of these materials, manual operation not only poses a direct threat to the health of workers, but also may cause material leakage due to improper operation or equipment failure, thereby causing environmental pollution and safety accidents.

[0018] Compared with the related art, the utility model has the beneficial effects that:

[0019] The raw material conveying device provided by the utility model aims to optimize the conveying process of raw materials in the chemical production process. Specifically, when it is necessary to safely and efficiently convey the raw materials in the tank body to the reaction kettle for subsequent reaction processing, first, the gas supply equipment is started, which will introduce inert gas into the gas inlet of the tank body through the first gas conveying pipe according to the set program. This step is the key starting point of raw material conveying. The introduction of inert gas not only provides power for subsequent extrusion conveying, but more importantly, it can effectively prevent unnecessary chemical reactions of raw materials with oxygen or other active components in the air during the conveying process, thereby ensuring the purity of the raw materials and the safety of the reaction.

[0020] With the inert gas continuously conveyed into the tank body by the gas supply equipment, the air pressure in the tank body gradually increases. This gradually increasing air pressure becomes an "invisible hand" that pushes the liquid raw materials forward, uniformly extruding the liquid raw materials in the tank body, forcing them to flow smoothly out of the discharge port of the tank body and into the discharge pipe connected thereto. The design of the discharge pipe fully considers the smoothness and sealing of the fluid, ensuring that the raw materials will not leak during the conveying process, further improving the safety and reliability of the entire system.

[0021] Finally, after precise guidance of the discharge pipe, the liquid raw materials are stably conveyed to the feed inlet of the reaction kettle and smoothly enter the reaction kettle, ready for the next step of reaction processing. During this process, the liquid raw materials are completely isolated from the outside world, avoiding the intrusion of external pollutants, and also eliminating the need for the separate transportation steps and the tediousness and uncertainty of manual operation in the traditional way, thereby greatly improving the safety and reliability of the raw material lifting and conveying.

[0032] As shown in Figure 1 The utility model provides a raw material conveying device, including jar body 100, first gas pipe 200, discharge pipe 300.

[0033] Jar body 100 has discharge port 110, gas inlet 120, and the gas inlet 120 is located the upper side of jar body 100, and the discharge port 110 is located the lower side of jar body 100, one end of first gas pipe 200 communicates with gas inlet 120, and the other end of first gas pipe 200 communicates with gas supply equipment, for conveying inert gas to jar body 100, one end of discharge pipe 300 communicates with discharge port 110, and the other end of discharge pipe 300 communicates with the feed inlet 410 of reaction kettle 400.

[0034] The raw material conveying device provided in the embodiment can convey the raw material in the jar body 100 to the reaction kettle 400 for reaction processing, first, the gas supply equipment is started, and the equipment will introduce inert gas into the gas inlet 120 of the jar body 100 according to the set program through the first gas pipe 200.

[0035] With the inert gas continuously conveyed into the jar body 100 by the gas supply equipment, the air pressure in the jar body 100 gradually increases. The gradually increasing air pressure becomes an "invisible hand" to push the liquid raw material forward, and uniformly extrudes the liquid raw material in the jar body 100, forcing it to flow out smoothly from the discharge port 110 of the jar body 100 along the established path and into the discharge pipe 300 connected thereto.

[0036] Finally, under the guidance of the discharge pipe 300, the liquid raw material is stably transported to the feed inlet 410 of the reaction kettle 400 and smoothly enters the reaction kettle 400, preparing for the next step of reaction processing. In this process, the liquid raw material is completely isolated from the outside world, avoiding the invasion of external pollutants, and also saving the possible sub-packaging and transportation steps in the traditional way and the tediousness and uncertainty of manual operation, thereby greatly improving the safety and reliability of the raw material lifting and conveying.

[0037] In some specific embodiments, in order to optimize the discharge efficiency of the liquid raw material and the stability of the tank body 100, the tank body 100 is arranged in a tilted manner relative to the horizontal plane. Specifically, the angle between the tank body 100 and the horizontal plane is defined as α, and the value of α is accurately limited to between 25° and 35°. This design involves many considerations.

[0038] Firstly, by tilting the tank body 100, we take advantage of gravity to make the liquid raw material in the tank body 100 more easily gather near the discharge port 110. Such a design brings significant advantages in actual operation: when the raw material needs to be discharged from the tank body 100, since the liquid has already concentrated near the discharge port 110, the amount of raw material remaining in the tank body 100 can be greatly reduced, thereby effectively avoiding waste of raw material.

[0039] On the other hand, the tank body 100 is arranged to have an angle of 25° to 35° with the horizontal plane, which is a deliberate choice. Within this range of inclination, two key factors can be cleverly balanced: one is to prevent the liquid raw material from sticking to the inner wall of the tank body 100, and the other is to ensure the stability of the tank body 100. If the inclination is too small, the liquid raw material may stick to the inner wall of the tank body 100 due to lack of sufficient gravity, resulting in incomplete discharge; if the inclination is too large, although it can further promote the gathering of liquid, it may cause the center of gravity of the tank body 100 to be unstable, increasing the risk of tipping and thus threatening the safety of operation. Therefore, the angle range of 25° to 35° is an ideal choice that can effectively avoid the sticking phenomenon and ensure the stability of the tank body 100. Such a design not only improves the discharge efficiency, but also enhances the reliability and safety of the equipment.

[0040] Specifically, in other embodiments of the present application, the angle between the tank body 100 and the horizontal plane can be 26°, 27°, 29°, 30°, 31°, 32°, 32.5°, 34°, 34.5°, etc., which will not be described one by one here.

[0041] In some specific embodiments, the raw material conveying device further comprises a control assembly, the first gas pipe 200 is provided with a first control valve 210 and a pressure gauge 220, the pressure gauge 220 is located between the first control valve 210 and the gas inlet 120, and the first control valve 210 and the pressure gauge 220 are respectively electrically connected with the control assembly. The core function of the control assembly is that it can intelligently adjust the opening degree and on-off of the first control valve 210 according to the pressure data measured by the pressure gauge 220. The realization of this function benefits from the preset pressure value setting in the control assembly. When the control assembly receives the data transmitted by the pressure gauge 220 and judges that it is greater than the preset pressure value, it will immediately send an instruction to the first control valve 210 through the control circuit, requiring it to reduce the opening degree or directly close. This operation aims to reduce the pressure in the tank 100, thereby reducing the conveying speed of the liquid raw material, so as to ensure that the chemical reaction in the reaction kettle 400 can be carried out under stable pressure and temperature conditions, and avoid that the reaction is out of control or the product quality is reduced due to too fast raw material supply.

[0042] On the contrary, when the pressure data received by the control assembly is less than the preset pressure value, it will send an instruction to increase the opening degree of the first control valve 210 through the control circuit. This operation aims to increase the pressure in the tank 100, thereby increasing the conveying speed of the liquid raw material, to ensure that the reaction kettle 400 can continuously obtain sufficient raw material supply and maintain normal production rhythm.

[0043] In some specific embodiments, the raw material conveying device further comprises a thermometer 420, the sensing end of the thermometer 420 is provided in the reaction kettle 400, the thermometer 420 is electrically connected with the control assembly, and the control assembly can adjust the opening degree and on-off of the first control valve 210 according to the temperature data measured by the thermometer 420. The role of the control assembly is particularly important here, it is not only the receiver of information, but also the maker of decisions and the commander of execution. The control assembly can intelligently compare the temperature data measured by the thermometer 420 with the preset temperature value. This preset temperature value is set based on the best reaction temperature range of the raw material in the reaction kettle 400, aiming to ensure that the reaction process is always in the best state.

[0044] When the temperature in the reaction kettle 400 is lower than the preset temperature value, it means that the current reaction speed may not reach the best, or the reaction has not been fully carried out. At this time, the control assembly will quickly respond by adjusting the opening degree of the first control valve 210 to increase the raw material transmission speed from the tank 100 to the reaction kettle 400. More raw materials entering the reaction kettle 400 will bring additional reaction heat, thereby gradually increasing the temperature in the reaction kettle 400 until the best reaction temperature range is reached.

[0045] On the contrary, if the temperature inside the reactor 400 is higher than the preset temperature value, it may mean that the reaction is too intense, there is a risk of overheating, or the conversion rate of the raw material has approached saturation. In this case, the control assembly will also quickly adjust the opening of the first control valve 210 to reduce the speed of raw material transmission from the tank 100 into the reactor 400. In this way, the reaction speed can be slowed down, the temperature inside the reactor 400 can be reduced, and overheating can be prevented to prevent the reaction from getting out of control or the product quality from being reduced.

[0046] In some specific embodiments, the discharge port 110 and the gas inlet 120 are respectively provided with second control valves 111 and third control valves 121; the second control valves 111 and the third control valves 121 are closed when the tank 100 is replaced or the feeding work is stopped, so as to avoid leakage and other problems of the tank 100.

[0047] In some specific embodiments, the discharge pipe 300 is provided with a fourth control valve 310, which is kept open in the feeding state to ensure that the raw material can be smoothly discharged from the tank 100. When the feeding is stopped, the fourth control valve 310 is quickly closed to prevent any incomplete discharge of the raw material or gas from flowing back to the tank 100, ensuring the cleanliness and safety of the system; the raw material conveying device further comprises a second gas conveying pipe 500, one end of the second gas conveying pipe 500 communicates with the discharge pipe 300, the other end of the second gas conveying pipe 500 communicates with a gas supply device, the communication position of the second gas conveying pipe 500 and the discharge pipe 300 is located between the fourth control valve 310 and the second control valve 111, and the second gas conveying pipe 500 is provided with a fifth control valve 510; so as to close the second control valve 111 and open the fifth control valve 510 after the raw material in the tank 100 is completely discharged, and use the gas supply device to convey inert gas into the discharge pipe 300, so as to facilitate the pressure feeding of the raw material in the discharge pipe 300 into the reactor 400, reduce the residue of the raw material in the discharge pipe 300, which not only helps to keep the discharge pipe 300 clean, but also effectively avoids the deterioration or blockage of the raw material in the pipeline, thereby ensuring the smoothness and efficiency of the entire raw material conveying process.

[0048] In some specific embodiments, the second control valve 111, the third control valve 121, the fourth control valve 310, and the fifth control valve 510 are respectively electrically connected with the control assembly, so as to realize automatic control during the raw material conveying process, reduce manual participation, and improve the safety of the embodiment.

[0049] In some specific embodiments, the inert gas provided by the gas supply device is nitrogen. This choice is not accidental, but is based on the stability and safety considerations of nitrogen in chemical properties. Nitrogen is a colorless, odorless, and odorless inert gas, which is chemically very stable and not easy to react with other substances. This property makes nitrogen a commonly used protective gas and purging gas in chemical production, which can effectively prevent the deterioration of raw materials due to oxidation during transportation and storage.

[0050] In addition, nitrogen also has lower density and viscosity, which makes it reduce resistance and improve transportation efficiency during transportation. At the same time, the cost of nitrogen is relatively low, easy to obtain and store, which also brings more convenience and economy to chemical production.

[0051] In some specific embodiments, the discharge pipe 300 is provided with a flow meter 320, which is specifically located at one end of the discharge pipe 300 close to the reaction kettle 400, to measure the consumption of raw materials of the reaction kettle 400, so as to realize accurate recording of the production process materials.

[0052] In some specific embodiments, the raw material conveying device further comprises a weighing assembly 600, and the tank body 100 is arranged on the weighing assembly 600. The weighing assembly 600 is used to weigh the weight of the tank body 100, so as to accurately measure the weight change of the tank body 100, that is, the conveying amount of raw materials in the tank body 100.
