Description

Technical Field

[0001] This invention belongs to the technical field of spray drying equipment, specifically a spray drying device for processing calcium lactate. Background Technology

[0002] Spray drying is a key process in the production of calcium lactate. It atomizes liquid materials and brings them into contact with hot air to dry them instantly into powder products. Its working principle is to use an atomizer to atomize the liquid material into tiny droplets, which then come into direct contact with hot air or other heat media in the drying tower to rapidly evaporate the water or other solvents in the liquid material. After the liquid material is dried into powder products in a very short time, it is discharged from the drying tower to a cyclone separator to achieve gas-solid separation and obtain the dried product.

[0003] For example, Chinese Patent Application No. 2019104802678 discloses a high-speed centrifugal spray dryer, which includes a high-temperature purification chamber and a drying tower located on one side of the high-temperature purification chamber. A mixing chamber is provided on one side of the high-temperature purification chamber, and an air supply pipe is fixedly installed on the top of the mixing chamber. This device facilitates the filtration of impurities in the material through a filter plate and facilitates the cleaning of impurities on the filter plate. However, the powder particles at the discharge hopper tend to stick together and clump together, which can easily form a bridging phenomenon, seriously hindering the smooth discharge of the finished product.

[0004] For example, Chinese patent application number 2023104130253 discloses a spray dryer and its air sweeping device, which includes a water-blocking sleeve fitted on the part of the air sweeping rod in the discharge section of the drying tower. The protruding end of the air sweeping rod after passing through the sealing structure is connected to a high-pressure blower. An interface is provided on the side of the protruding end, and an air seal inlet is opened on the side of the sealing structure. This device introduces airflow between the water-blocking sleeve and the air sweeping rod through the air sweeping rod to prevent fine powder in the drying tower from entering the gap and the transmission box. However, it cannot perform cleaning in a suitable way according to different situations, which can easily lead to over-cleaning or under-cleaning.

[0005] Based on the above solutions, in actual use, the walls of the drying chamber of traditional spray drying equipment will be covered with layers of calcium lactate powder of varying thicknesses and hardness, ranging from loose to stubbornly clumped. Traditional methods cannot select the appropriate cleaning method according to different situations, which can easily lead to over- or under-cleaning. The temperature in the hopper area is low, and the dried calcium lactate powder is prone to condensation due to moisture absorption or residual moisture on the surface, causing the powder particles to stick together, clump together, and even form bridging phenomena in the conical hopper, which seriously hinders the smooth discharge of the finished product.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1.

The cleaning component then cleans the material in a timely manner using different methods depending on the situation. For loose material layers, normal cleaning is maintained by the cleaning strip. For stubborn accumulated material, the air pressure is automatically increased to enhance the scraping force of the cleaning strip, and auxiliary air blowing is activated at appropriate times.

[0022] 2. This invention utilizes a combination of a scraper and an elastic blowing mechanism. The scraper physically removes calcium lactate powder from the hopper, while the hot air from the blowing device compensates for the heat and evaporates moisture to prevent new calcium lactate powder particles from sticking together. The two work together to effectively solve the problem of calcium lactate powder particles sticking and bridging at the hopper, ensuring that the dried calcium lactate powder has good flowability, smooth feeding, and improved product yield.

[0033] like Figures 1 to 8 As shown, a spray drying device for processing calcium lactate according to the present invention includes a spray drying component 1, a separation component 2, and a cleaning component 3. The separation component 2 is disposed on one side of the spray drying component 1 for collecting products and treating exhaust gas. The cleaning component 3 is disposed inside the spray drying component 1 for automatically cleaning materials adhering to the inner wall of the device.

[0034] like Figure 2 , Figure 3As shown, the spray drying assembly 1 includes a drying chamber 101, a feeding hopper 102 is provided below the drying chamber 101, a conveying pipe 105 is provided on the surface of the feeding hopper 102 for discharging a gas-solid mixture, an air distributor 103 is provided above the drying chamber 101 for uniformly introducing hot air into the drying chamber 101, an atomizer 104 is provided inside the drying chamber 101 for atomizing calcium lactate solution or suspension into tiny droplets, a hot air duct is provided at one end of the air distributor 103, and a heater is provided at the end of the hot air duct away from the air distributor 103 for providing a drying heat source.

[0035] like Figure 2 As shown, the separation component 2 includes a primary cyclone separator 201, which is connected to the conveying pipe 105. A connecting pipe 202 is provided at the end of the primary cyclone separator 201 away from the conveying pipe 105. A secondary cyclone separator 203 is provided at the end of the connecting pipe 202 away from the primary cyclone separator 201. An air supply pipe 204 is provided at the end of the secondary cyclone separator 203 away from the connecting pipe 202.

[0036] In use, the inlet of the primary cyclone separator 201 is connected to the hopper 102 via the conveying pipe 105 for primary separation of the gas-solid mixture, collecting most of the calcium lactate powder. The gas outlet of the primary cyclone separator 201 is connected to the inlet of the secondary cyclone separator 203 via the connecting pipe 202 for secondary separation to capture finer powder. The gas outlet of the secondary cyclone separator 203 is connected to the induced draft fan 205 via the air supply pipe 204. The induced draft fan 205 provides the negative pressure power required by the system. Finally, the exhaust gas is purified by the dust collector 206 before being discharged, ensuring that environmental protection standards are met.

[0037] like Figure 5 , Figure 6 As shown, the cleaning component 3 includes a transmission box 301, which is located below the hopper 102. A rotating frame 302 is provided inside the transmission box 301, and a main air pipe 303 is provided at the center of the surface of the rotating frame 302.

[0038] A drive motor is mounted on one side of the transmission box 301 to provide rotational power. An air supply pipe 314 is provided at the end of the transmission box 301 away from the hopper 102. The main air pipe 303 passes through and extends to the outside of the transmission box 301. The main air pipe 303 is connected to the air supply pipe 314. A high-pressure blower is provided at the end of the air supply pipe 314 away from the main air pipe 303. The air supply pipe 314 and the high-pressure blower work together to provide the high-pressure gas required for cleaning. A control valve 304 is mounted on the surface of the main air pipe 303 to open and close the high-pressure airflow.

[0039] It is worth noting that when the drive motor is turned on, it drives the transmission mechanism inside the transmission box 301 to rotate, thereby enabling the rotating frame 302 to rotate.

[0040] like Figure 6 As shown, an elastic blowing mechanism 305 is provided at the end of the main air pipe 303 away from the rotating frame 302, which is used to clean the side wall area of ​​the hopper 102. The elastic blowing mechanism 305 includes an elastic tube 3051, which is connected to the main air pipe 303. A mounting base 3052 is provided at the end of the elastic tube 3051 away from the main air pipe 303, and a blower 3053 is provided on one side of the mounting base 3052.

[0041] The surface of the mounting base 3052 is provided with a limit bracket 3055, and the end of the main air pipe 303 near the control valve 304 is provided with a limit seat 3054. The surface of the limit seat 3054 is provided with a limit groove that is compatible with the limit bracket 3055.

[0042] like Figure 6 , Figure 7 As shown, a cleaning air pipe 306 is provided on one side of the main air pipe 303. A scraper 307 is provided at the end of the cleaning air pipe 306 near the hopper 102 for scraping off the calcium lactate powder layer adhering to the inner wall of the hopper 102. Multiple cleaning strips 313 are mounted on the cleaning air pipe 306.

[0043] The surface of the cleaning air pipe 306 is provided with a sleeve 308, and the inside of the sleeve 308 is provided with a movable rod 309. The end of the movable rod 309 away from the cleaning air pipe 306 is provided with a detection seat 312, and the end of the detection seat 312 away from the movable rod 309 is fixedly connected to the cleaning strip 313.

[0044] It is worth noting that multiple cleaning strips 313 are evenly arranged on the cleaning air pipe 306 along the length of the drying chamber 101.

[0045] like Figure 8 As shown, a return spring 310 is provided on the surface of the movable rod 309. One end of the return spring 310 is connected to the sleeve 308, and the other end of the return spring 310 is connected to the movable rod 309. A compression spring 311 is provided at the end of the movable rod 309 near the detection seat 312, and the end of the compression spring 311 away from the movable rod 309 is connected to the detection seat 312.

[0046] The sleeve 308 has an internal groove that matches the movable rod 309, and one end of the movable rod 309 has a storage groove that matches the detection seat 312.

[0047] In practical use, traditional spray drying equipment often results in layers of calcium lactate powder of varying thickness and hardness adhering to the inner wall of the drying chamber 101, ranging from loose to stubbornly clump-like. Traditional methods cannot effectively address these variations, leading to either over- or under-cleaning. Furthermore, the lower temperature in the discharge hopper 102 area causes the dried calcium lactate powder to easily absorb moisture or condense due to surface residue, leading to particle adhesion, clumping, and even bridging within the conical discharge hopper 102. This severely hinders the smooth discharge of the finished product. To address this issue, the following measures are taken:

[0048] In operation, the heater and induced draft fan 205 are first started. Hot air is evenly introduced into the top of the drying chamber 101 through the air distributor 103. At the same time, the calcium lactate liquid is atomized into fine droplets by the atomizer 104 and sprayed into the drying chamber 101. The droplets come into contact with the hot air, and the moisture evaporates rapidly to form calcium lactate powder, which then falls into the feed hopper 102. The dried powder and exhaust gas are driven by the airflow generated by the induced draft fan 205 and enter the primary cyclone separator 201 through the conveying pipe 105. Most of the powder is separated and collected here and discharged from the discharge port of the primary cyclone separator 201. The exhaust gas containing fine powder enters the secondary cyclone separator 203 for secondary separation. The remaining powder is discharged from the discharge port of the secondary cyclone separator 203. Finally, the gas separated by the two stages is introduced into the dust collector 206 by the induced draft fan 205 for deep purification before being discharged.

[0049] Simultaneously, the controller starts the drive motor, which drives the rotating frame 302, main air pipe 303, and cleaning air pipe 306 to rotate together via the transmission box 301. During the rotation of the cleaning air pipe 306, the scraper 307 rotates along with the cleaning air pipe 306, thereby rotating and scraping off the powder adhering to the conical inner wall of the hopper 102. Then, under the action of the high-pressure blower, gas is delivered to the main air pipe 303 through the air supply pipe 314 and then to the cleaning air pipe 306. Under the action of the gas, the return spring 310 is compressed, and the movable rod 309 moves away from the sleeve 308. During this process, the movable rod 309 pushes the detection seat 312 and the cleaning strip 313 to move a preset distance together until the side of the cleaning strip 313 away from the detection seat 312 is in contact with the inner wall of the drying chamber 101, thereby causing the cleaning strip 313 to rotate along with the cleaning air pipe 306 to perform preliminary scraping and cleaning of the calcium lactate powder adhering to the inner wall of the drying chamber 101.

[0050] It is worth noting that the controller monitors the contact pressure between the sweeping strip 313 and the inner wall of the drying chamber 101 in real time through a pressure sensor inside the detection seat 312, and uses this as a feedback signal to precisely control the extension distance of the movable rod 309 by adjusting the gas pressure introduced through the sleeve 308. When the value fed back by the pressure sensor reaches the preset initial value (i.e., the pressure value at which the sweeping strip 313 and the inner wall of the drying chamber 101 make good contact), the movable rod 309 stops moving, and the distance it moves is the preset distance.

[0051] To monitor the adhesion of calcium lactate powder to the inner wall of the drying chamber 101 in real time, a pressure sensor is installed inside the detection seat 312. The pressure sensor detects the pressure on the cleaning strip 313. First, the initial value is recorded when the cleaning strip 313 is in contact with the inner wall of the drying chamber 101. Then, the pressure sensor detects the pressure on the cleaning strip 313 in real time and records it as the detection value. The difference between the initial value and the detection value is calculated and compared with the preset value to determine the adhesion of calcium lactate powder to the inner wall of the drying chamber 101. At the same time, the compression amount of the compression spring 311 can also be calculated. Then, the cleaning component 3 is adjusted according to the actual situation to select different cleaning methods for different adhesion conditions of calcium lactate powder to the inner wall of the drying chamber 101.

[0052] During the above process, if the difference between the initial value and the detected value of the pressure sensor is within the standard range, it indicates that the calcium lactate powder on the inner wall of the drying chamber 101 is not strongly adhered or is loose. At this time, the cleaning strip 313 can meet the normal cleaning requirements.

[0053] If the difference between the initial value and the detected value of the pressure sensor exceeds the preset value, it indicates that the calcium lactate powder on the inner wall of the drying chamber 101 has strong adhesion and high hardness, and there are stubborn deposits with local protrusions. The cleaning bar 313 and the detection seat 312 will be subjected to reverse pressure. This pressure first compresses the compression spring 311 between the movable rod 309 and the detection seat 312. At this time, the controller controls the high-pressure blower to increase the amount of gas in the sleeve 308 through the air supply pipe 314, the main air pipe 303 and the cleaning air pipe 306. Under the action of gas pressure, the reset spring 310 continues to be compressed, and the movable rod 309 continues to move away from the sleeve 308. During this process, the movable rod 309 pushes the detection seat 312 and the cleaning bar 313 to move together, while the compression spring 311 continues to be compressed, thereby increasing the scraping pressure of the cleaning bar 313. During the rotation, the cleaning bar 313 scrapes and cleans the calcium lactate powder layer on the inner wall of the drying chamber 101.

[0054] It is worth noting that the surface of the movable rod 309 is provided with an elliptical groove (such as...). Figure 8As shown in the figure, the movable rod 309 is equipped with an air valve (not shown in the figure). In the above process, since the position of the elliptical groove on the movable rod 309 is fixed, the controller determines the extension displacement of the movable rod 309 by detecting the deformation of the return spring 310. When the deformation of the return spring 310 reaches the preset threshold, it indicates that the movable rod 309 has extended to a specific stroke. At this time, the elliptical groove just moves outside the end of the sleeve 308. The controller then controls the air valve to open. At this time, the gas in the sleeve 308 is discharged along the gap between the elliptical groove on the movable rod 309 and the sleeve 308 under the action of the air valve. This allows the high-pressure gas to blow away the calcium lactate powder loosened by the cleaning strip 313, which facilitates the cleaning of the scraped powder and blows the loosened powder away from the wall surface, realizing the coordinated cleaning of scraping and blowing to prevent secondary adhesion.

[0055] During the drying process, the temperature near the air distributor 103 in the drying chamber 101 is higher than the temperature at the hopper 102. When the dried calcium lactate powder falls into the hopper 102, condensation easily forms on its surface. The high ambient humidity causes the dew point temperature to drop, resulting in the calcium lactate powder particles at the hopper 102 sticking and clumping together. Simply scraping off the calcium lactate powder particles adhering to the conical inner wall of the hopper 102 using the scraper 307 is insufficient. Therefore, the controller opens the control valve 304, and under the action of the high-pressure blower, gas is delivered to the elastic jetting mechanism 305 to heat the calcium lactate powder particles at the hopper 102. To compensate for heat loss caused by temperature drop and evaporate moisture from the surface of calcium lactate powder particles, high-pressure gas sequentially enters the elastic tube 3051 of the elastic blowing mechanism 305 through the air supply pipe 314 and the main air pipe 303. The elastic blowing mechanism 305 rotates with the main air pipe 303, and the blowers 3053 on it blow high-pressure air onto the inner wall surface of the hopper 102. The high-pressure gas with heat carries away the moisture on the surface of the calcium lactate powder particles in the hopper 102, accelerating the drying process, preventing new calcium lactate powder particles from sticking together, and using the impact and shearing force of the airflow to loosen and blow off the calcium lactate powder adhering to the area, making it easier to discharge. Since the wet layer on the surface of the calcium lactate powder particles is directly removed and the adhesion is broken by the scraper 307, and the blower 3053 on the elastic blowing mechanism 305 carries away the moisture and disperses the calcium lactate powder particles by airflow, the problem of adhesion and bridging of calcium lactate powder particles at the discharge hopper 102 can be effectively solved by combining the blowing operation of the scraper 307 and the elastic blowing mechanism 305.

[0056] It is worth noting that the gas pressure and flow rate introduced into the elastic tube 3051 can be precisely adjusted by the control valve 304. The elastic tube 3051 can be a bellows. When gas at a certain pressure is introduced into the elastic tube 3051, its axial length will change with the internal pressure due to the characteristics of the bellows. When the blower 3053 is not performing a powerful blowing operation, the amount of gas introduced into the elastic tube 3051 by the control valve 304 can cause the elastic tube 3051 to undergo elastic deformation, causing it to stretch or contract, thereby adjusting the blowing height of the blower 3053. During this process, the blower 3053 moves vertically, driving the limit frame 3055 to move together in the limit groove on the limit seat 3054, thereby adjusting the initial working height of the blower 3053.

[0057] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
