Description

Technical Field

[0001] This utility model relates to the field of atomization equipment technology, and in particular to an atomization device for a centrifugal spray drying tower. Background Technology

[0002] Centrifugal spray drying towers are highly efficient continuous drying equipment. Their core principle is to use centrifugal atomizing devices to disperse liquid materials into tiny droplets, which then come into direct contact with the high-speed hot airflow inside the tower, causing the moisture in the droplets to evaporate rapidly. The drying process is completed in a very short time, ultimately obtaining powder or granular solid products. It is widely used in many industrial fields such as food, medicine, chemical, and building materials, and is a key piece of equipment for realizing the large-scale conversion of "liquid materials → solid powder".

[0003] The atomization mechanism of existing centrifugal spray drying towers mostly consists of an atomizing disc and a drive system. In operation, liquid material is conveyed to the center of the atomizing disc through the feed pipe. The atomizing disc is then driven by a motor and a shaft to rotate at high speed. The high-speed rotation of the atomizing disc generates a strong centrifugal force, which throws the material in the center toward the edge. Under the action of centrifugal force, the material first forms a uniform liquid film on the surface of the atomizing disc. When the liquid film reaches the edge of the atomizing disc, it is torn into countless tiny droplets with uniform particle size distribution because the centrifugal force exceeds the surface tension. These droplets diffuse into the drying tower in an umbrella shape, completing the atomization process.

[0004] However, due to the adhesive properties of liquid materials, some liquid materials may adhere to the inner wall of the atomizing disc, causing some materials to fail to be effectively ejected. Furthermore, long-term adhesion can easily lead to accumulation and blockage, affecting the atomization effect. Utility Model Content

[0005] The technical problem to be solved by this utility model is that, due to the certain viscosity of liquid materials, some liquid materials may adhere to the inner wall of the atomizing disk, resulting in some materials not being effectively ejected, and long-term adhesion can easily cause accumulation and blockage, affecting the atomization effect.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an atomizing device for a centrifugal spray drying tower, comprising: an atomizing disc, wherein a shaft is provided in the middle of the atomizing disc, the shaft is fixedly connected to the output end of a motor through a coupling, wherein the motor is fixedly installed on the drying tower to drive the shaft and the atomizing disc to rotate; and a striking device, wherein the striking device is provided on the motor, wherein the striking device continuously strikes the surface of the atomizing disc during its rotation, causing the atomizing disc to vibrate and reducing the material adhering to the inner wall of the atomizing disc.

[0007] Preferably, the striking device includes: a support rod, which is detachably mounted on the motor via an assembly assembly, wherein the end of the support rod away from the motor is fixedly connected to a perforated rod; a striking block, which is movably mounted on the perforated rod via a spring rod, wherein the spring rod slides up and down along the inner wall of the perforated rod, wherein one end of the spring rod is fixedly connected to the perforated rod and the other end is fixedly connected to the striking block; and a wave ring, which is fixedly connected to the atomizing disc, wherein the striking block remains in contact with the wave ring under the push of the spring rod.

[0008] The effect achieved by the above components is as follows: By setting up a striking device, when the motor drives the shaft and the atomizing disc to rotate, the atomizing disc drives the wave ring to rotate. At the same time, under the reaction force of the spring in the spring rod, the spring rod pushes the striking block to always keep it in contact with the wave ring. During the rotation of the wave ring, the striking block is continuously pushed up by the protruding parts on its surface, and then reset under the push of the spring and embedded in the concave parts on the surface of the wave ring, continuously striking the wave ring. After the wave ring is struck, it vibrates along with the atomizing disc. The vibration of the atomizing disc shakes the material attached to its inner wall, causing the material to fall off the inner wall of the atomizing disc. This completes the anti-adhesion treatment of the material, reducing the adhesion of liquid material to the inner wall of the atomizing disc, which causes some material to fail to be effectively thrown off, and long-term adhesion can easily lead to accumulation and blockage, affecting the atomization effect. This improves the use effect and internal cleanliness of the atomizing disc.

[0009] Preferably, the striking block has a spherical groove on the side away from the spring rod, wherein a steel ball is rolled inside the spherical groove.

[0010] The effect achieved by the above components is as follows: by setting steel balls, when the striking block comes into contact with the wave ring, the steel balls will make priority contact with the wave ring, and under the rolling action of the steel balls, the steel balls will roll while in contact with the wave ring, thereby reducing the friction between the striking block and the wave ring.

[0011] Preferably, a rubber pad is fixed to the side of the spring rod away from the striking block.

[0012] The effect achieved by the above components is as follows: by setting the rubber pad, the rubber pad can fit against the surface of the hole rod when the spring rod is reset, and the end of the spring rod away from the striking block is separated from the hole rod, thereby reducing the collision wear between the spring rod and the hole rod.

[0013] Preferably, the corrugated ring is composed of a low-carbon steel plate and an alloy wear-resistant layer.

[0014] The effects achieved by the above components are as follows: the wear-resistant layer is mainly composed of chromium alloy, with the addition of alloy components such as manganese, molybdenum, and niobium. The carbides are distributed in a fibrous manner, and the surface hardness can reach HRC-. It has excellent wear resistance, good impact resistance and good heat resistance, which can effectively improve the life and strength of the wave ring.

[0015] Preferably, the assembly component includes: a sleeve, which is fixedly connected to the motor, wherein the sleeve is sleeved on the shaft, and bolts are threadedly connected to the inner wall of the hole in the sleeve; and a perforated plate, which is fixedly connected to the support rod, wherein the perforated plate covers the sleeve and is fixed by bolts.

[0016] The effect achieved by the above components is as follows: by setting up the assembly components, the support rod is first moved manually to drive the perforated plate to move. When the perforated plate moves to the position covering the surface of the sleeve, the inner wall of the perforated plate coincides with the inner wall of the hole on the sleeve. At this time, the bolts are manually screwed into the holes of the perforated plate and the sleeve to fix the position of the perforated plate and the support rod, thereby completing the assembly and fixation between the support rod and the motor. At the same time, the support rod can be disassembled later, improving the flexibility of use and the convenience of maintenance of the striking device.

[0017] Preferably, a positioning post is fixedly connected to the sleeve, wherein the positioning post is inserted into the perforated plate to limit its movement.

[0018] The effect achieved by the above components is as follows: by setting the positioning post, when the perforated plate moves to the position covering the sleeve surface, the positioning post can be inserted into the perforated plate to assist in limiting the perforated plate, reducing the shaking or tilting of the perforated plate during use, and further improving the installation stability of the perforated plate.

[0019] Preferably, the bolt has multiple anti-slip strips fixed to the nut position, and the multiple anti-slip strips are arranged at equal intervals.

[0020] The effect achieved by the above components is that by setting anti-slip strips, the friction between the hand and the bolt can be increased, reducing the chance of slipping when manually turning the bolt.

[0021] The beneficial effects of this utility model are:

[0022] By incorporating a tapping device, some of the material adhering to the inner wall of the atomizing disc can be knocked off, reducing the amount of liquid material adhering to the inner wall of the atomizing disc. This prevents some material from being effectively ejected and avoids long-term accumulation and blockage, which can affect the atomization effect. As a result, the atomizing disc's performance and internal cleanliness are improved. Attached Figure Description

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0032] The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] In this embodiment:

[0034] Figure 1-6 The atomizing device of a centrifugal spray drying tower shown includes: an atomizing disc 1, a shaft 3 disposed in the middle of the atomizing disc 1, the shaft 3 being fixedly connected to the output end of a motor 2 via a coupling, wherein the motor 2 is fixedly mounted on the drying tower to drive the shaft 3 and the atomizing disc 1 to rotate; and a striking device 4 disposed on the motor 2, wherein the striking device 4 continuously strikes the surface of the atomizing disc 1 during its rotation, causing the atomizing disc 1 to vibrate and reducing material adhesion to the inner wall of the atomizing disc 1.

[0035] Figure 2-6The striking device 4 shown includes: a support rod 41, which is detachably mounted on the motor 2 via an assembly assembly 5, wherein a perforated rod 42 is fixedly connected to the end of the support rod 41 away from the motor 2; a striking block 44, which is movably mounted on the perforated rod 42 via a spring rod 43, wherein the spring rod 43 slides up and down along the inner wall of the perforated rod 42, wherein one end of the spring in the spring rod 43 is fixedly connected to the perforated rod 42, and the other end is fixedly connected to the striking block 44; and a wave ring 47, which is fixedly connected to the atomizing disc 1, wherein the striking block 44 is kept in contact with the wave ring 47 under the push of the spring rod 43. By setting the striking device 4, when the motor 2 drives the shaft 3 and the atomizing disc 1 to rotate, the atomizing disc 1 drives the wave ring 47 to rotate, and at the same time, the spring in the spring rod 43... Under the force, the spring rod 43 pushes the striking block 44 to always keep it in contact with the wave ring 47. As the wave ring 47 rotates, the striking block 44 is continuously pushed up by the protruding part on its surface. Then, under the push of the spring, it returns to its original position and is embedded in the concave part on the surface of the wave ring 47, continuously striking the wave ring 47. After the wave ring 47 is struck, it vibrates together with the atomizing disk 1. The vibration of the atomizing disk 1 shakes the material attached to its inner wall, causing the material to fall off the inner wall of the atomizing disk 1. This completes the anti-adhesion treatment of the material, reduces the adhesion of liquid material to the inner wall of the atomizing disk 1, and prevents some material from being effectively thrown off. Long-term adhesion can easily cause accumulation and blockage, affecting the atomization effect. This improves the use effect and internal cleanliness of the atomizing disk 1.

[0036] Figure 2-6 The striking block 44 shown has a spherical groove on the side away from the spring rod 43, in which a steel ball 46 is rolled. By setting the steel ball 46, when the striking block 44 contacts the wave ring 47, the steel ball 46 makes priority contact with the wave ring 47. Under the rolling action of the steel ball 46, the steel ball 46 rolls while contacting the wave ring 47, thereby reducing the friction between the striking block 44 and the wave ring 47. A rubber pad 45 is fixed to the side of the spring rod 43 away from the striking block 44. By setting the rubber pad 45, the rubber pad 45 can fit against the surface of the hole rod 42 when the spring rod 43 is reset, and separate the end of the spring rod 43 away from the striking block 44 from the hole rod 42, reducing the collision wear between the spring rod 43 and the hole rod 42.

[0037] Figure 2-6 The wave ring 47 shown is composed of a low-carbon steel plate and an alloy wear-resistant layer. The wear-resistant layer is mainly composed of chromium alloy, and also contains alloy components such as manganese, molybdenum, and niobium. The carbides are distributed in a fibrous manner, and the surface hardness can reach HRC58-62. It has excellent wear resistance, good impact resistance and good heat resistance, which can effectively improve the service life and strength of the wave ring 47.

[0038] Figure 4-5The assembly component 5 shown includes: a sleeve 51, which is fixedly connected to the motor 2, and the sleeve 51 is sleeved on the shaft 3. The inner wall of the hole on the sleeve 51 is threaded with a bolt 52; and a perforated plate 55, which is fixedly connected to the support rod 41. The perforated plate 55 covers the sleeve 51 and is fixed with bolts 52. By setting up the assembly component 5, the support rod 41 is first manually moved to move the perforated plate 55. When the perforated plate 55 moves to the position covering the surface of the sleeve 51, the inner wall of the perforated plate 55 coincides with the inner wall of the hole on the sleeve 51. At this time, the bolts 52 are manually screwed into the holes of the perforated plate 55 and the sleeve 51 to fix the position of the perforated plate 55 and the support rod 41, thereby completing the assembly and fixation between the support rod 41 and the motor 2. At the same time, the support rod 41 can be disassembled later, improving the flexibility of use and the convenience of maintenance of the striking device 4.

[0039] Figure 4-5 A positioning post 54 is fixedly connected to the sleeve 51 shown. The positioning post 54 is inserted into the perforated plate 55 to limit its movement. By setting the positioning post 54, when the perforated plate 55 moves to the position covering the surface of the sleeve 51, the positioning post 54 can be inserted into the perforated plate 55 to assist in limiting the perforated plate 55, reducing the shaking or tilting of the perforated plate 55 during use, and further improving the installation stability of the perforated plate 55. Multiple anti-slip strips 53 are fixedly connected to the nut position of the bolt 52. The multiple anti-slip strips 53 are arranged at equal intervals. By setting the anti-slip strips 53, the friction between the hand and the bolt 52 can be increased, reducing the possibility of slippage when manually turning the bolt 52.

[0040] Working principle: During use, liquid material is conveyed to the center of atomizing disc 1 through the feed pipe. Then, atomizing disc 1 is driven by motor 2 and shaft 3 to rotate at high speed. The high-speed rotation of atomizing disc 1 generates a strong centrifugal force, which throws the material in the center to the edge. Under the action of centrifugal force, the material first forms a uniform liquid film on the surface of atomizing disc 1. When the liquid film reaches the edge of atomizing disc 1, it is torn into countless tiny droplets with uniform particle size distribution because the centrifugal force exceeds the surface tension. These droplets diffuse into the drying tower in an umbrella shape, completing atomization.

[0041] First, manually move the support rod 41 to move the perforated plate 55. When the perforated plate 55 moves to the position covering the surface of the sleeve 51, the inner wall of the perforated plate 55 coincides with the inner wall of the hole on the sleeve 51. At this time, manually screw the bolt 52 into the hole of the perforated plate 55 and the sleeve 51 to fix the position of the perforated plate 55 and the support rod 41, thereby completing the assembly and fixation between the support rod 41 and the motor 2.

[0042] When the motor 2 drives the shaft 3 and the atomizing disc 1 to rotate, the atomizing disc 1 causes the wave ring 47 to rotate. At the same time, under the reaction force of the spring in the spring rod 43, the spring rod 43 pushes the striking block 44 to always keep it in contact with the wave ring 47. As the wave ring 47 rotates, the striking block 44 is continuously pushed up by the protruding part on its surface. Then, under the push of the spring, it resets and embeds into the concave part on the surface of the wave ring 47, continuously striking the wave ring 47. After the wave ring 47 is struck, the atomizing disc 1 vibrates together. The vibration of the atomizing disc 1 shakes the material attached to its inner wall, causing the material to fall off the inner wall of the atomizing disc 1, thus completing the anti-adhesion treatment of the material.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
