Description

Technical Field

[0001] The present invention relates to the technical field of chemical drying, in particular to a device for grading, processing and drying daily chemical raw material particles. Background Art

[0002] Chemical raw material particles can be divided into organic chemical raw material particles and inorganic chemical raw material particles. Organic chemical raw material particles can be divided into alkanes and their derivatives, alkenes and their derivatives, alkynes and their derivatives, quinones, aldehydes, alcohols, ketones, phenols, ethers, anhydrides, esters, organic acids, carboxylates, carbohydrates, etc.

[0003] In the existing technology, many chemical raw material particles generally need to go through processes such as crystallization and centrifugation to obtain wet products, and then go through drying, mixing, cooling, and packaging to become finished products.

[0004] Existing drying devices have a single drying method, usually using high-temperature gas to directly dry chemicals, which easily causes the chemicals to denature due to heat and affects their chemical properties.

[0019] 3. Beneficial effects

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] (1) In this solution, the detection component adjusts the temperature of several heating layers according to the humidity data, thereby selecting a heating temperature suitable for the raw material particles in different humidity periods, which is not easy to cause the chemical substances to denature due to heat.

[0022] (2) Since the raw material particles just entering the drying chamber have the highest humidity, the temperature of the top heating layer is the highest, thereby quickly drying and evaporating the humidity on the surface of the raw material particles. At this time, a large amount of evaporated steam will flow upward under the blowing of the wind at the bottom of the drying chamber, making it difficult for a large amount of steam to enter the drying chamber, so that the raw material particles subsequently dried in the drying chamber are less affected by the evaporated steam, thereby shortening the drying time of the raw material particles.

[0023] (3) The raw material particles are separated and isolated into several parts through the distribution cavity formed by multiple distribution fluidization plates. The raw material particles are not easy to pile up together during drying, thereby improving the drying speed and efficiency of the raw material particles. In addition, the raw material particles will continuously collide with the distribution fluidization plates during the falling process, so that the position of the raw material particles is constantly changed, which can fully contact with the external heat and has the advantage of all-round drying.

[0024] (4) The vibration motor can transmit vibration energy to the distribution fluidization plate, so that the distribution fluidization plate itself vibrates continuously. The distribution fluidization plate in a vibrating state makes it difficult for the raw material particles to adhere to the distribution fluidization plate during the drying process, thus solving the problem of the distribution fluidization plate being blocked by the raw material particles.

[0025] (5) As the heating temperature of the heating layer decreases from top to bottom, the bending amplitude of the thermal deformation part of each part gradually becomes smaller, so that the falling speed of the raw material particles entering the material distribution cavity is gradually accelerated, and the discharge speed of the gradually dried raw material particles is accelerated, further reducing the problem of thermal denaturation of chemical substances.

[0026] (6) When the annular feeding member is working, the raw material particles will automatically fall into the quantitative conveying trough under the action of gravity. The quantitative conveying trough will separate the excess raw material particles through the annular fixing member, so that the device can dry the raw material particles quantitatively each time, so that the amount of raw material particles dried each time will not be too much or too little, thereby effectively improving the drying efficiency.

[0027] (7) The raw material particles dried in the first drying section are transported to the second drying section through the material guide pipe, and the waste heat pipe can transport the dried gas to the second drying section, so that the waste heat gas is used to circulate and dry the raw material particles, which has the effect of energy saving and environmental protection.

Specifically, the flat distribution fluidization plate 4 is used to prevent raw material particles from remaining on the surface; the thermal deformation part 5 is made of a bimetallic spring sheet, so that the curvature of the thermal deformation part 5 under different temperature conditions is inconsistent. For example, when the thermal deformation part 5 distributed on the top layer is heated to the highest temperature, its own curvature will increase, slowing down the falling speed of the raw material particles, thereby increasing the drying time; both ends of the thermal deformation part 5 are provided with outwardly extending protrusions, and the protrusions are fixedly connected to the vibrating end of the vibration component 7. Specifically, the vibration component 7 is preferably a vibration motor, which can transmit vibration energy to the distribution fluidization plate 4 through the protrusions, so that the distribution fluidization plate 4 itself vibrates continuously. The distribution fluidization plate 4 in a vibrating state makes it difficult for raw material particles to adhere to the distribution fluidization plate 4 during the drying process, thereby solving the problem of the distribution fluidization plate 4 being blocked by raw material particles; the protrusions are distributed in the middle of the thermal deformation part 5, and when the thermal deformation part 5 is deformed, it bends with the protrusions as the axis. Specifically, the thermal deformation part 5 is connected and fixed to the outside world through the protrusion, so that the thermal deformation part 5 as a whole is not easily interfered with by the outside world when it is deformed. There is a gap between the thermal deformation part 5 and the drying chamber, and the gap diameter is smaller than the diameter of the raw material particles.

[0046] See also Figure 1-2 and Figure 7 Two rotatably connected annular feed members 9 are provided in the drying shell 1, wherein a rotating groove for accommodating the rotation of the annular feed member 9 is opened on the drying shell 1, and the two annular feed members 9 correspond to the first drying section 2 and the second drying section 3 respectively. It should be noted that the two annular feed members 9 can rotate independently to realize the transportation of raw materials. A quantitative conveying groove 10 is provided at intervals on the inner side of the annular feed member 9.

[0047] See also Figure 1 and Figure 7-9The drying shell 1 is also provided with an annular fixing part 11 that fits with the quantitative conveying groove 10, wherein part of the inner wall of the drying shell 1 extends toward the annular fixing part 11 and is fixedly connected to the annular fixing part 11; a gas flow groove is opened on the lower side of the first annular part, and a waste heat pipe 14 connected to the gas flow groove is provided in the first annular part, wherein "b" represents a condenser, a condenser is provided on the outer side of the bottom of the first annular part, and the waste heat pipe 14 is connected to the condenser, wherein "c" represents a drain outlet, and a drain outlet connected to the drain end of the condenser is provided at the bottom of the drying shell 1. Specifically, after the quantitative conveying trough 10 discharges the raw material particles, gas containing a large amount of steam will enter the quantitative conveying trough 10 and be transported to the gas flow trough through the quantitative conveying trough 10. The gas will further flow into the waste heat pipe 14. Since the waste heat pipe 14 is built into the first ring part, the outside of the first ring part is heated, and then the raw material particles in the quantitative conveying trough 10 are preheated to realize the recycling of hot steam; and, when the hot steam enters the condenser, the steam in the hot steam will condense and be discharged outward from the drain port, so that the steam remains in a dry state.

[0048] See also Figure 1-3 and Figure 8-10The annular fixing member 11 is provided with a dividing port 12 which is connected with the first drying section 2 and the second drying section 3; the annular fixing member 11 includes a first annular member corresponding to the first drying section 2 and a second annular member corresponding to the second drying section 3. The first annular member is provided with a feed port 13, and a detection component is provided in the feed port 13, and the detection component is electrically connected to the heating layer 8; a driving component is provided in the drying shell 1, and the driving component includes gears corresponding to the two annular feeding members 9 respectively, and the outer periphery of the annular feeding member 9 is provided with a tooth groove which meshes with the gear; the outlet end of the waste heat pipe 14 is connected with the lower side of the second drying section 3, and the upper side of the second drying section 3 is provided with an exhaust pipe connected to the outside world, and a fan component is provided on the outside of the drying shell 1, and the fan component is used to transport gas to the first drying section 2. Specifically, the raw material particles dried in the first drying section 2 are transported to the second drying section 3 through the material guide pipe, and the waste heat pipe 14 can transport the dried gas to the second drying section 3, thereby utilizing the waste heat gas to circulate and dry the raw material particles, which has the effect of energy saving and environmental protection. In addition, at least one fan in the fan assembly is connected to the exhaust pipe, thereby improving the exhaust efficiency of the exhaust pipe. The drive assembly also includes a servo motor 15 connected to the gear transmission, and a hinged door body is provided on the drying shell 1 corresponding to the position of the servo motor 15. Specifically, when the servo motor 15 is started, it can drive the fixedly connected gear to rotate, and then drive the annular material feeding member 9 to rotate, realizing power transmission; the openable and closable door body facilitates maintenance personnel to repair internal parts. The annular fixing member 11 is fixedly connected to the inner wall of the drying shell 1. The outer periphery of the annular fixing member 11 is provided with a smooth fitting groove, which matches the quantitative conveying groove 10. The dispensing port 12 is located at the top of the annular fixing member 11, and the dispensing port 12 is provided in plurality. Specifically, the quantitative conveying trough 10 is located in the fitting trough, thereby preventing the raw material particles from falling from the quantitative conveying trough 10; through the spaced-apart material distribution ports 12, the raw material particles in the quantitative conveying trough 10 can fall downward from multiple material distribution ports 12 under the action of gravity, thereby falling evenly into the drying chamber. A reflux pipe 16 connected to the second annular member is provided at the bottom of the second drying section 3, wherein "d" represents an opening, an opening is provided at the bottom of the annular fixing member 11, and an opening and closing material removal plate is provided on one side of the bottom of the second annular member. Specifically, the raw material particles in the reflux pipe 16 connected to the second drying section 3 and the raw material particles at the feed port 13 can all fall into the quantitative conveying trough 10 through the opening. Among them, the openable material removal plate on the second annular member facilitates the removal and collection of the dried raw material particles.

[0049] Among them, the detection component is a humidity sensor, the model is preferably AM2320, the heating layer 8 uses a heating wire, and a processor is integrated in the detection component, and the processor is preferably an AVR single-chip microcomputer. The processor is used to obtain the current humidity data of the raw material particles entering the feed port 13 detected by the detection component, and control the temperature of several heating layers 8 according to the humidity data; for example, the current humidity of the raw material particles is 60°, at this time, the processor controls the corresponding heating temperature of the top heating layer 8 to 85°C, thereby heating and drying the raw material particles passing through this area, and the temperature of the heating layer 8 located below will gradually decrease, so that the heating temperature suitable for the raw material particles in different humidity periods is selected, which is not easy to cause the chemical substances to be denatured by heat It should be noted that, for the heating temperature of raw material particles with different humidity, the staff can store the corresponding temperature data in the processor in advance. Since the humidity of the raw material particles just entering the drying chamber is the highest, the temperature of the uppermost heating layer 8 is the highest, thereby quickly drying and evaporating the humidity on the surface of the raw material particles. At this time, a large amount of evaporated steam will flow upward under the blowing of the wind at the bottom of the drying chamber, so that a large amount of steam is not easy to enter the drying chamber, so that the raw material particles subsequently dried in the drying chamber are less affected by the evaporated steam, thereby shortening the drying time of the raw material particles; when the raw material particles enter the drying chamber, the dividing chamber formed by multiple dividing fluidization plates 4 separates the raw material particles into several parts, and then separates them into several parts for drying. When drying, the raw material particles are not easy to pile up together, thereby improving the drying speed and efficiency of the raw material particles, and the raw material particles will continuously collide with the distribution fluidization plate 4 during the falling process, so that the position of the raw material particles is constantly changing, and can fully contact with the external heat, so that the drying is more uniform, and the situation of local moisture is reduced; wherein, the vibration component 7 is preferably a vibration motor, and an insulating shell is provided on the outside of the vibration motor, and the vibration motor can transmit vibration energy to the distribution fluidization plate 4, so that the distribution fluidization plate 4 itself is constantly vibrating, and the distribution fluidization plate 4 in a vibrating state makes it difficult for the raw material particles to adhere to the distribution fluidization plate 4 during the drying process, thereby solving the problem of the distribution fluidization plate 4 being blocked by raw material particles; wherein, the thermal deformation part 5 adopts The bimetallic spring sheet makes the curvature of the thermal deformation part 5 in different temperature states inconsistent. For example, when the thermal deformation part 5 distributed on the uppermost layer is subjected to the highest heating temperature, its curvature will increase, slowing down the falling speed of the raw material particles, thereby increasing the drying time. Since the heating temperature of the heating layer 8 decreases from top to bottom, the curvature of the thermal deformation part 5 of each part gradually decreases, so that the falling speed of the raw material particles entering the material distribution cavity is gradually accelerated, and the discharge speed of the gradually dried raw material particles is accelerated, so that the chemical raw material particles are not easily denatured by heat. Among them, the stretching layer 6 is made of high-temperature resistant elastic rubber material, and will stretch itself according to the changes of the thermal deformation part 5, thereby ensuring the use effect;As the annular feed member 9 rotates, the raw material particles automatically fall into the quantitative conveying trough 10 under the action of gravity. The quantitative conveying trough 10 separates the excess raw material particles under the annular fixing member 11, so that the device can dry the raw material particles quantitatively each time, so that the amount of raw material particles dried each time is not too much or too little, thereby effectively improving the drying efficiency. Through the spaced-apart distribution openings 12, the raw material particles in the quantitative conveying trough 10 can fall downward from the multiple distribution openings 12 under the action of gravity and fall evenly into the drying chamber. In addition, the device is in a sealed state during the drying process, so as not to pollute the external environment and achieve good use effect.

[0050] Compared with the existing technology, the detection component adjusts the temperature of several heating layers 8 according to the humidity data, so as to select the heating temperature suitable for the raw material particles in different humidity periods, which is not easy for the chemical substances to be denatured by heat, and the distribution fluidization plate 4 can be deformed according to different heating temperatures, so that the falling speed of the raw material particles is gradually accelerated, the discharge speed of the raw material particles is increased, and the chemical substances are not easily denatured by heat. The distribution fluidization plate 4 is in a vibrating state, so that the raw material particles are not easily adhered to the distribution fluidization plate 4 during the drying process, which solves the problem of the distribution fluidization plate 4 being blocked by raw material particles.

Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
