Description

Technical Field

[0001] The utility model belongs to the technical field of drying equipment, in particular to an air guide device of a spray drying tower. Background Art

[0002] With the development of society and technology, equipment in various fields has been greatly improved. Spray drying tower is a kind of equipment used for drying biological pesticides, medicines, and food microorganisms. When it is in use, it can dry the liquid into finished products in an extremely short time, which greatly improves the work efficiency. In order to make the hot air fully contact, the hot air is generally guided to the appropriate position by setting an air guide device to reduce energy waste.

[0003] After retrieval, the publication number CN219630635U and the application date 2023.07.26 disclose a wind guide device for a spray drying tower, including a bottom plate; a support rod is fixedly arranged on the bottom plate, and a tower body is fixedly arranged on the other end of the support rod, a spray pipe is fixedly arranged inside the tower body, a connecting box is fixedly arranged on the outside of one end of the spray pipe, a jet plate is fixedly arranged at the bottom end of the connecting box, air holes are arranged around the inside of the jet plate, and hot air pipes are respectively arranged on both sides of the connecting box; the utility model transports the spray to the inside of the tower body through the spray pipe, and the hot air is transported to the inside of the connecting box through the hot air pipe, and is ejected through the air holes opened on the jet plate. At this time, the direction of the hot air is guided by the connecting box and the air holes, and the basic direction is vertical downward movement, which reduces the possibility of droplets adhering to the top of the inner wall of the tower body, and at the same time, the hot air flows out through the air holes, thereby improving the uniformity of the hot air flowing into the drying chamber and improving a certain drying effect of the hot air.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. When the air guide device of the spray drying tower is in use, the motor drives the first scraper, the second scraper and the third scraper to rotate to clean the inner wall of the tower body. In this way, the atomized particles on the inner wall of the tower body will adhere to the surface of the scraper, which will still affect the cleanliness of subsequent product processing. At the same time, it will increase the number of manual cleaning and replacement, with high work intensity and low efficiency.

[0006] 2. When in use, the air guide device of the spray drying tower guides the hot air to move vertically downward through the connection box and the jet plate arranged vertically downward. However, the pressure at the center of the tower body is relatively high, which will cause the hot air on both sides to move upward, resulting in poor uniformity, resulting in a large number of droplets adhering to the outside of the top of the inner wall of the tower body, which will affect the subsequent use and drying effect. To this end, we provide an air guide device for a spray drying tower to solve the above problems. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0034] See also Figures 1 to 5 The utility model is an air guide device for a spray drying tower, comprising a tower body 1 and a scraper 103 arranged on one side of the bottom end thereof, a moving groove 1032 is opened on one side of the interior of the scraper 103, a pushing assembly 2 is arranged inside the moving groove 1032; the pushing assembly 2 comprises a fixed plate 201 and a servo motor 202 installed at the center position of the bottom thereof, the output shaft of the servo motor 202 passes through the bearing at the center position of the bottom of the fixed plate 201 and is connected to a threaded rod 2021 through a coupling.

[0035] Specifically, an observation window 101 is arranged above the front end face of the tower body 1, a driving mechanism 102 is arranged at the center position of the bottom of the tower body 1, a cleaning brush 1031 is arranged at the vertical section of the outer wall of the scraper 103, a partition 104 is fixedly connected to the upper inner wall of the tower body 1, a ball rod 105 is rotatably connected in the ball groove inside the partition 104, a pressing plate 1051 is fixedly connected to the top of the ball rod 105, a jet box 106 is installed at the bottom end of the ball rod 105, and a hot air pipe 1061 is arranged at the center position of the outer wall of one side of the jet box 106, and the hot air pipe The other end of 1061 passes through the inner wall of the tower body 1, and a spray pipe 107 is arranged at the top center of the tower body 1.

[0041] Furthermore, the operation of the asynchronous motor 301 drives the rotating shaft 3011 to rotate through the coupling, and rotates the toothed disc 3012 at the bottom thereof, and the gears on the outer wall of the toothed disc 3012 are meshed and connected with the gears on the outer wall of the gear ring 3022, thereby playing a transmission role, and the lowered protrusion 3023 will apply force to the outer surface of the pressure plate 1051, and under the action of the ball rod 105 and the ball groove, the pressure plate 1051 and the jet box 106 are tilted, and the gear ring 3022 is rotatably installed at the bottom of the lifting ring 3021, thereby playing a role of auxiliary rotation and limiting.

[0042] The operation process of this embodiment is as follows: first, the spray is transported to the inside of the tower body 1 through the spray pipe 107, and then hot air is introduced into the jet box 106 through the hot air pipe 1061, and then the hot air is ejected from the bottom of the jet box 106 to the bottom of the tower body 1, and the spray is dried, and then the electric push rod 302 is started, and the telescopic end of the electric push rod 302 extends to push the lifting ring 3021 to move downward, and the lifting ring 3021 causes the gear ring 3022 to descend and be placed on the outside of the toothed disc 3012 on one side, and then the asynchronous motor 301 is started, and the output shaft of the asynchronous motor 301 rotates to drive the rotating shaft 3011 to rotate through the coupling, and the rotation of the rotating shaft 3011 will drive the bottom toothed disc 3012 to rotate, wherein the gear on the outer wall of the toothed disc 3012 meshes with the gear on the outer wall of the gear ring 3022 The toothed disc 3012 is connected with the gear ring 3022 at the bottom of the lifting ring 3021 when it rotates, and the protrusion 3023 at the bottom of the gear ring 3022 is rotated in a circular manner, and the protrusion 3023 exerts pressure on the outer surface of the lower pressure plate 1051, wherein the bottom of the pressure plate 1051 is connected to the jet box 106 through the action of the ball rod 105, and the ball rod 105 is located in the ball groove inside the partition 104. Therefore, when the outer surface of the pressure plate 1051 is subjected to cyclical pressure, the ball rod 105 is rotated inside the ball groove, and the jet box 106 at its bottom continuously adjusts the direction of the bottom spray hole, so that the hot air can be sprayed to various positions in the tower body 1 more evenly, further reducing the possibility of droplets adhering to the top of the inner wall of the tower body 1, and the effect is good.
