Description

Technical Field

[0001] The present invention relates to the technical field of powder processing, and particularly to a spray drying tower for powder grease processing. Background Art

[0002] Powder grease is commonly used in the addition of food in daily life, and has good dispersibility, water solubility and stability. When used in various foods, it can improve the nutritional value and calorific value, improve the instant solubility and reconstitutability, and improve the taste to make the food more delicious. At present, in the common drying tower, hot air is mainly injected directly from the top to dry the powdered grease material in a liquefied state ejected from the spraying port. Since the hot air enters the inside of the tower wall and directly evaporates the water on the surface of the ejected liquefied material, the material is granulated. However, when the material is ejected, it is affected by the conversion of hot air, and the water vapor evaporating the material will produce a protective effect, resulting in a situation where the material cannot be completely dried locally. At the same time, affected by gravity and the impact of hot air, the incompletely dried material sinks to the bottom, resulting in mixing with some of the dried material and causing caking, which affects the discharge quality of the material. Summary of the Invention

[0007] Furthermore, a scraping mechanism is arranged on the outer surface of the protective cover. The scraping mechanism is fixedly connected to two T-shaped rods on the outer surface of the protective cover. The two T-shaped rods are symmetrically arranged with respect to the center of the protective cover. A hollow limiting rod is rotatably connected to the side of the T-shaped rod far from the protective cover. Two through limiting sliding grooves are opened on the outer surface of the hollow limiting rod.

A pushing frame is fixedly connected to the side of the restraint arm far from the hollow limiting rod; Among them, the outer surface of the rotating joint slides inside the limiting sliding groove of the hollow limiting rod.

[0008] Furthermore, a vibration mechanism is arranged on the outer surface of the rotating shaft. The vibration mechanism is rotatably connected to a rotating platform on the outer surface of the rotating shaft. A plurality of cross-like rods are fixedly connected to the top and bottom of the rotating platform. The plurality of cross-like rods are arranged in a circumferential array with respect to the center of the rotating platform; Furthermore, curve sliding groove platforms are arranged on the top and bottom of the rotating platform.

A spring is fixedly connected to the side of the impact arm far from the rotating platform. The side of the spring far from the rotating platform is fixedly connected to the bottom of the groove rotating plate.

[0009] The present invention has the following beneficial effects: 1. When the present invention is in use, hot air is injected from the entrance of the main body. The impact of the air drives the windmill to rotate along the inner wall of the main body. At the same time, since the bottom of the windmill in the main body is connected to the tower cover, while the hot air can drive the windmill to rotate, the excess hot air will directly pour into the interior of the tower cover. The hot air contacts the liquid powder grease material sprayed inside for evaporation effect, and a drying reaction is carried out on the powder grease material. As the hot air continuously enters the interior of the windmill, the hot air inside the windmill enters the heat dissipation pipe through the second guide column and is released. Part of the hot air will be released through the holes around the heat dissipation pipe, and the other part will enter the interior of the conical tower and be released. The hot air released inside the conical tower will flow upward and diffuse inside the conical tower. The diffused hot air conducts a drying reaction on a part of the liquid material sprayed into the interior of the tower cover. Under the protection of the drying hood, a part of the heat flow will flow upward from the center. After the material is dried under the influence, it is thrown out by the rotation of the conical tower driven by the windmill, avoiding the agglomeration of the dried material at the top of the conical tower, dispersing a part of the liquid material to promote the drying degree and progress, achieving the effect of reducing the agglomeration of the liquid material during drying and increasing the drying speed of the liquid material, thereby further improving the number and rate of drying reactions on the material and enhancing the drying effect.

[0010] 2. When the present invention is in use, injecting hot air from the main body directly affects the interior of the tower cover. The too-fast impact speed of the hot air may cause the sprayed material not to be completely dried, resulting in the fall of some wet materials. The convection mechanism in the middle aggregates the hot air inside the tower cover, blows it up and down to make the material be affected by the hot air multiple times inside and dry, making better use of the hot air circulation to dry the material. The hot air is injected from the upper part, and the downward force is greater than the upward force. Even if the fan at the bottom blows the hot air or the material upward, affected by the upper fan and the injection of hot air, the two airflows will not make the material float in the air for a long time. Affected by the upper part, it will act downward and float, enabling the material to move inside the drying tower to achieve a more effective drying reaction, achieving the movement of the material affected inside the tower, contacting the hot air injected from the top multiple times for drying reaction, flipping through multiple movements, and achieving the effect of more comprehensively contacting the hot air for drying, increasing the drying speed. At the same time, because of the continuous movement, it also avoids the material staying in one position after drying, resulting in over-drying of the material and causing it to become charred.

[0011] 3. When the present invention is in use, since the drying reaction requires a process, the material that is powdered under the influence of hot air has a certain adhesiveness during the process. Mainly between the convection, when the sliding block of the scraping mechanism is operating, the rotation of the fan drives the sliding block to scrape the material attached to the outer surface of the shield, avoiding adhesion and accumulation, and preventing the material from being continuously dried by hot air due to long-term adhesion to the surface, resulting in over-drying of the material. Since the sliding block continuously scrapes the surface as the equipment operates, it has a relative impact on the movement of the material, further avoiding the situation of material damage.

[0012] 4. When the present invention is in use, the vibration mechanism inside the shield works, continuously hitting and impacting the device, affecting the material remaining on the device, causing the material to fall off and normally fall to the bottom, avoiding excessive material aggregation and caking. Especially when the material falls onto the surface of the conical tower during the operation of the drying mechanism and is not thrown out in time, the residual material is made to fall off by using the vibration impact force, avoiding adhesion, and to a certain extent, better optimizing the effect of material falling off, so that the material falls off after being dried as required.

[0013] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The outer surface of the shield 207 is provided with a scraping mechanism 4. The scraping mechanism 4 is fixedly connected to two T-shaped rods 401 on the outer surface of the shield 207. The two T-shaped rods 401 are symmetrically arranged with the shield 207 as the center. A hollow limiting rod 402 is rotatably connected to the side of the T-shaped rod 401 away from the shield 207.

The two restraint arms 403 are symmetrically arranged with the center of the T-shaped rod 401 as the center. This design establishes a scraping mechanism 4 on the outer surface of the shield 207 to scrape the surface of the shield 207, preventing materials from adhering to the surface of the shield 207 after drying or during the drying process, and avoiding damage to the materials caused by long-term adhesion of the materials to the surface of the shield 207.

[0022] A vibration mechanism 5 is provided on the outer surface of the rotating shaft 206. The vibration mechanism 5 is rotatably connected to a rotating platform 501 on the outer surface of the rotating shaft 206. A plurality of cross-like rods 502 are fixedly connected to both the top and bottom of the rotating platform 501. The plurality of cross-like rods 502 are arranged in a circular array with the center of the rotating platform 501 as the center. This design is to establish the positions of the plurality of cross-like rods 502 to facilitate subsequent influence through the rotating shaft 206. Curve chute platforms 503 are provided on both the top and bottom of the rotating platform 501. The two curve chute platforms 503 are symmetrically arranged with the center of the rotating platform 501 as the center. The two curve chute platforms 503 are rotatably connected to the outer surface of the rotating shaft 206. This design is to establish the orientation of the curve chute platforms 503, and through the rotational drive of the rotating shaft 206, the two curve chute platforms 503 slide on the surface of the rotating shaft 206 to generate a driving force to avoid power loss of the equipment, and effectively utilize the impact of hot air to achieve a better separation effect on the materials. On one side of the curve chute table 503 away from the rotary table 501, several impact arms 504 are fixedly connected. On the side of the impact arm 504 away from the rotary table 501, a spring is fixedly connected. The side of the spring away from the rotary table 501 is fixedly connected to the bottom of the groove rotating plate 302.

[0023] During use, before starting, connect the input fan equipment to the air inlet of the main body 1, and connect the bottom to the discharge port. After checking and ensuring there are no errors, start the equipment. After starting the equipment, inject hot air into the air injection port of the top main body 1 by the inlet fan equipment (not specified). The hot air enters the inside of the tower cover 101 through the windmill 103 inside the main body 1. The windmill 103 inside the main body 1 rotates due to the continuous injection of hot air. Since the inside of the windmill 103 is hollow, while the hot air pushes the windmill 103 to rotate, it also enters the inside of the windmill 103. A part of the hot air that does not enter the inside of the windmill 103 directly enters the inside of the tower cover 101. The liquid material is injected into the inside of the tower cover 101 by the feed spray 102. A part of the hot air that directly enters the inside of the tower cover 101 will first carry out a drying reaction on the material. Since the material is sprayed in a fan shape, the sprayed material cannot fully contact the directly entering hot air. At this time, the windmill 103 at the top is driven by the hot air, driving the guide column 201 and the base 202 connected to the bottom to rotate. The hot air injected into the inside of the windmill 103 will move through the air guide groove inside the guide column 201 and release a part when passing through the heat dissipation pipe 205 to raise the surrounding temperature. The hot air causes a part of the liquid material inside the fan-shaped area to evaporate moisture. Another part of the hot air will pass through the heat dissipation pipe 205 to reach the inside of the drying hood 204. Since the conical tower 203 is conical and has a certain curvature, the entering hot air has a certain impact, impacting the outer surface of the conical tower 203 and then diffusing. The diffused hot air will rise along the inner wall of the drying hood 204 to carry out a part of the evaporation and drying reaction on the sprayed liquid material. Since the windmill 103 is pushed by the hot air to rotate, the windmill 103 drives the drying mechanism 2 to rotate, and the dried material is separated from the surface of the conical tower 203 by the rotational force, preventing the dried material from accumulating on the surface of the conical tower 203. Then, use the dispersed heat flow to dry the material on the inner wall of the material, which can further promote the drying reaction and improve the operation efficiency to a certain extent. During the operation of the device, the convection mechanism 3 is arranged to generate air convection inside the tower cover 101. The rotation of the windmill 103 drives the drying mechanism 2 to rotate on the surface of the shield 207. The rotation shaft 206 at the bottom of the base 202 is rotated by the windmill 103. The driving block 301 connected to the surface by rotation remains stationary, and the groove rotating plate 302 at the bottom follows the rotation shaft 206 to rotate. Since there are two driving blocks 301 and groove rotating plates 302 on the outer surface of the rotation shaft 206, which are symmetrically arranged around the center of the rotation shaft 206, the driving block 301 and groove rotating plate 302 at the bottom are also affected. The limiting block 304 slides inside the sliding groove on the top of the groove rotating plate 302 under the influence of the groove rotating plate 302. The sliding of the limiting block 304 affects the front and back movement of the elastic rod 303. The connecting arm 305 rotatably connected to the limiting block 304 is affected to pull the rotating arm 306, and the fan 307 rotatably connected to the rotating arm 306 is affected to rotate. Under the influence of the symmetrical arrangement of the two fans 307, rotation generates a convection state. The convection mechanism 3 is arranged in a circular array of two around the center of the rotation shaft 206. The convection generated by the rotation of the two symmetrical fans 307 allows the hot air to circulate and alternate inside the tower cover 101, affecting the flow of the sprayed liquid material multiple times. The continuous injection of hot air at the top makes the top flow rate greater than the blowing force of the bottom fan 307. The convection generated in this way allows the hot air or dried material to circulate and not stay in one position, creating a path without remaining in the same place and finally falling into the bottom outlet. This enables some liquid materials that were not dried immediately or materials that did not completely evaporate moisture to circulate again, promoting the circulation of hot air inside the tower cover 101 and conducting multiple drying reactions on the material, further improving the drying efficiency. At the same time, the material is kept flowing to avoid damage to the material caused by excessive drying; At the same time, during the operation of the convection mechanism 3, the rotation of the fan 307 causes the rotating block 406 connected to the fan 307 to pull the support rod 405 to rotate. The rotating joint at the end of the support rod 405 away from the rotating block 406 is pulled to rotate and expand simultaneously on the surface of the restraint arm 403. The outer surface of the pulled rotating joint slides inside the limit sliding groove opened on the hollow limit rod 402. At the same time, the pushing frame 407 fixedly connected to the side of the restraint arm 403 away from the rotating joint slides along the outer surface of the shield 207, scraping the residual material on the outer surface of the shield 207. The convection generated by the fan 307 causes it to move again, promoting the detachment reaction. The existing pushing frame 407 scrapes the outer surface of the shield 207 to prevent the material from continuously sticking to the outer surface of the shield 207; During the operation process, inside the shield 207, the vibration mechanism 5 is affected by the rotation of the rotating shaft 206. A number of cross-shaped rods 502 fixedly connected to the top and bottom of the rotating table 501 are arranged in a circular array, and rotate on the outer surface of the curve chute table 503. There are two curve chute tables 503 symmetrically arranged at the center of the rotating shaft 206 and rotate on the outer surface of the rotating shaft 206. Therefore, through rotation, the rotating shaft 206 drives a number of cross-shaped rods 502 at the top and bottom of the rotating table 501 to rotate on the outer surface of the curve chute table 503, causing the curve chute table 503 to approach the bottom of the groove rotating plate 302. The top of the curve chute table 503 is provided with impact arms 504, which are arranged in a circular array centered on the curve chute table 503. The springs at the ends of the impact arms 504 close to the groove rotating plate 302 are fixedly connected to the bottom of the groove rotating plate 302. This can disperse some kinetic energy, avoid excessive impact force on the impact arms 504 caused by the too-fast rotation of the rotating shaft 206. At the same time, the impact force can affect the materials on the outer surface of the cone tower 203 to vibrate and fall off, and the impact force can also affect the materials on the outer surface of the push skeleton 407 to fall off to a certain extent, avoiding the situation of material adhesion on the equipment. The rotation of the windmill 103 driven by hot air drives the mechanism to affect the materials inside the tower cover 101, causing excessive materials on the surface to contact hot air and evaporate the moisture therein, improving the drying reaction efficiency; When the use is finished, after separating the required materials inside, turn off the machine, check whether there is any residue inside, and then perform the required cleaning to complete the operation.
