Description

Technical Field

[0001] This utility model belongs to the field of starch processing technology, specifically relating to a spray drying tower for starch processing. Background Technology

[0002] Starch (amylum) is a high-molecular-weight carbohydrate, a polysaccharide polymerized from glucose molecules. Various equipment is needed to process starch, including a spray drying tower. This tower is a drying device that separates the raw material liquid into droplets in an atomizer and obtains a powder-shaped product by direct contact between hot air or other gases and the droplets.

[0003] Existing spray drying towers often fail to spray droplets evenly, resulting in uneven contact between the droplets and other components. This reduces the quality of spray drying and causes inconvenience for users. This issue is a problem that urgently needs to be addressed by those in the field. Utility Model Content

[0004] The purpose of this invention is to propose a spray drying tower for starch processing, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a spray drying tower for starch processing, comprising a spray drying tower body, a discharge pipe fixedly connected to the bottom of the spray drying tower body, an air inlet pipe and a drive motor fixedly connected to the top of the spray drying tower body, a drive shaft fixedly connected to the output shaft of the drive motor via a coupling, a movable disc and a limiting block fixedly connected to the outer wall of the drive shaft, a guide groove provided on one side of the limiting block, a pressing rod fixedly connected to the bottom of the movable disc, a rotary atomizer movably connected to the top of the spray drying tower body, and a fixed connection to the top of the rotary atomizer. The movable block has a connecting groove on its outer wall. A support pipe is fixedly connected to the bottom of the rotary atomizer, and a nozzle is fixedly connected to the bottom of the support pipe. By setting up a spray drying tower body, a discharge pipe, an air inlet pipe, a drive motor, a drive shaft, a movable disc, a limit block, a squeezing rod, a rotary atomizer, a movable block, a support pipe, a nozzle, a guide groove, and a connecting groove, it is convenient to drive the rotary atomizer to rotate intermittently at equal angles. This facilitates the rotary atomizer to drive the nozzle to rotate through the support pipe, so that the mist droplets are evenly sprayed into the interior of the spray drying tower body and make more uniform contact with the gas, thereby improving the uniformity of the spray drying operation.

[0006] Preferably, the diameter of the limiting block is smaller than that of the movable disk, and the limiting block and the movable block form a rotating structure. Specifically, the limiting block and the movable disk are distributed in a "convex" shape, and the height of the limiting block is greater than that of the movable block, which facilitates the setting of the limiting block and ensures that the driving shaft drives the movable disk and the limiting block to rotate outside the movable block.

[0007] Preferably, the limiting block is matched with the movable block through a guiding groove, and the movable block is distributed in a "cross" shape. Specifically, the guiding groove and the end of the movable block are distributed in a dislocation manner. Subsequently, after the movable disk drives the extrusion rod to slide into the connecting groove, the limiting block drives the guiding groove to contact the end of the movable block, which ensures that the movable disk drives the movable block to rotate effectively through the extrusion rod.

[0008] Preferably, the extrusion rod is matched with the connecting groove, and the connecting grooves are distributed at equal angles along the axial center line of the movable block. Specifically, the connecting groove and the end plate of the movable block are distributed in a "concave" shape, which facilitates the movable disk to drive the extrusion rod to slide into the connecting groove and then drive the movable block to rotate intermittently by a certain angle through the connecting groove.

[0009] Preferably, arc-shaped grooves are provided at the four corners of the movable block, and the arc-shaped grooves and the limiting block are located on the same axial center line. Specifically, the diameter of the arc-shaped groove is larger than that of the limiting block, which further ensures the effective rotation of the movable block.

[0010] Preferably, the rotary atomizer penetrates through the top wall of the spray drying tower body through a bearing, and the rotary atomizer is rotationally connected with the spray drying tower body through the bearing. Specifically, the bottom of the rotary atomizer extends into the interior of the spray drying tower body, which facilitates the rotary support work of the rotary atomizer through the bearing and facilitates the subsequent multi-angle spraying of droplets by the rotary atomizer.

[0011] Preferably, a number of support pipes are distributed at equal angles, and a number of spray heads are distributed at equal intervals at the bottom of the support pipes. Specifically, three support pipes are provided, and the included angle between the two farthest support pipes is 90°. Therefore, after the movable block rotates 90°, the support pipes drive the spray heads to spray the interior of the spray drying tower body by 360°, which further facilitates the uniform contact between the droplets and the gas and ensures the uniformity of spray drying.

[0012] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows: In the present utility model,

[0013] (1) By setting up a spray drying tower body, discharge pipe, air inlet pipe, drive motor, drive shaft, movable disc, limit block, extrusion rod, rotary atomizer, movable block, support pipe, nozzle, guide groove and connecting groove, it is convenient to drive the rotary atomizer to rotate intermittently at equal angles, which is conducive to the rotary atomizer driving the nozzle to rotate through the support pipe, so that the mist droplets are evenly sprayed into the interior of the spray drying tower body and make more uniform contact with the gas, thereby improving the uniformity of spray drying work.

[0020] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-4, the present utility model provides a technical solution: a spray drying tower for starch processing, including a spray drying tower body 1, a discharge pipe 2 is fixedly connected to the bottom of the spray drying tower body 1, an air inlet pipe 3 and a driving motor 4 are fixedly connected to the top of the spray drying tower body 1 respectively, an output shaft of the driving motor 4 is fixedly connected to a driving shaft 5 through a coupling, an activity disk 6 and a limiting block 7 are fixedly connected to the outer wall of the driving shaft 5 respectively, a guiding groove 13 is opened on one side of the limiting block 7, a pressing rod 8 is fixedly connected to the bottom of the activity disk 6, a rotary atomizer 9 is movably connected to the top of the spray drying tower body 1, an activity block 10 is fixedly connected to the top of the rotary atomizer 9, a connecting groove 14 is opened on the outer wall of the activity block 10, a support pipe 11 is fixedly connected to the bottom of the rotary atomizer 9, a nozzle 12 is fixedly connected to the bottom of the support pipe 11. By providing the spray drying tower body 1, the discharge pipe 2, the air inlet pipe 3, the driving motor 4, the driving shaft 5, the activity disk 6, the limiting block 7, the pressing rod 8, the rotary atomizer 9, the activity block 10, the support pipe 11, the nozzle 12, the guiding groove 13 and the connecting groove 14, it is convenient to drive the rotary atomizer 9 to rotate at equal angles intermittently, which is beneficial for the rotary atomizer 9 to drive the nozzle 12 to rotate through the support pipe 11, so that the droplets are evenly sprayed into the interior of the spray drying tower body 1 to make more uniform contact with the gas, thereby improving the uniformity of the spray drying operation.

[0022] Preferably, the diameter of the limiting block 7 is smaller than that of the activity disk 6, and the limiting block 7 and the activity block 10 form a rotating structure. Specifically, the limiting block 7 and the activity disk 6 are distributed in a "convex" shape, and the height of the limiting block 7 is greater than that of the activity block 10, so that by providing the limiting block 7, it is convenient to ensure that the driving shaft 5 drives the activity disk 6 and the limiting block 7 to rotate outside the activity block 10.

[0023] Preferably, the limiting block 7 cooperates with the activity block 10 through the guiding groove 13, and the activity block 10 is distributed in a "cross" shape. Specifically, the guiding groove 13 and the end of the activity block 10 are distributed in a dislocation manner. Then, after the activity disk 6 drives the pressing rod 8 to slide into the interior of the connecting groove 14, the limiting block 7 drives the guiding groove 13 to contact the end of the activity block 10, so as to ensure that the activity disk 6 drives the activity block 10 to rotate effectively through the pressing rod 8.

[0024] Preferably, the pressing rod 8 cooperates with the connecting groove 14, and the connecting groove 14 is distributed at equal angles along the axial center line of the activity block 10. Specifically, the connecting groove 14 and the end plate of the activity block 10 are distributed in a "concave" shape, so that after the activity disk 6 drives the pressing rod 8 to slide into the interior of the connecting groove 14, the connecting groove 14 drives the activity block 10 to rotate intermittently by a certain angle.

[0025] Preferably, the four corners of the movable block 10 are provided with arc-shaped grooves, and the arc-shaped grooves and the limiting block 7 are located on the same axial center line. Specifically, the diameter of the arc-shaped grooves is larger than the diameter of the limiting block 7, thereby further ensuring the effective rotation of the movable block 10.

[0026] Preferably, the rotary atomizer 9 passes through the top wall of the spray drying tower body 1 via a bearing, and the rotary atomizer 9 is rotatably connected to the spray drying tower body 1 via the bearing. Specifically, the bottom of the rotary atomizer 9 extends into the interior of the spray drying tower body 1, which facilitates the rotational support of the rotary atomizer 9 via the bearing, and facilitates the subsequent multi-angle spraying of droplets by the rotary atomizer 9.

[0027] Preferably, there are several support pipes 11 distributed at equal angles, and several nozzles 12 are distributed at equal intervals at the bottom of the support pipes 11. Specifically, there are three support pipes 11, and the included angle between the two support pipes 11 furthest apart is 90°. This makes it convenient for the movable block 10 to rotate 90°, so that the support pipes 11 drive the nozzles 12 to spray the interior of the spray drying tower body 1 in 360°, thereby facilitating uniform contact between the droplets and the gas and ensuring the uniformity of spray drying.

[0028] In use, first start the drive motor 4, which drives the drive shaft 5 to rotate. The drive shaft 5 then drives the movable disc 6 and the limiting block 7 to rotate. The limiting block 7 prevents the movable block 10 from accidentally reversing, and causes the movable disc 6 to slide the extrusion rod 8 into the connecting groove 14. This causes the movable disc 6 to compress the movable block 10 by the extrusion rod 8, rotating it 90°. At the same time, the limiting block 7 causes the guide groove 13 to contact the end plate of the movable block 10, thus ensuring the rotation of the movable block 10 and causing it to rotate and atomize. The atomizer 9 rotates 90° under the support of the bearing, which in turn causes the three support tubes 11 to rotate 90°. The continued start of the drive motor 4 causes the movable disc 6 to drive the movable block 10 to rotate intermittently by 90°. This causes the atomizer 9 to drive the nozzle 12 to rotate intermittently by 90° through the support tubes 11, thereby evenly spraying the droplets into the interior of the spray drying tower body 1. This allows the droplets to have more uniform contact with the gas, avoiding the situation where continuous spraying of droplets leads to limited contact, and thus improving the uniformity and efficiency of spray drying.
