Description

Technical Field

[0001] This utility model relates to the field of drying oven technology, specifically to a raw material constant temperature drying device. Background Technology

[0002] A drying oven is a common device for dehydrating and drying objects. Common drying ovens are generally divided into two main categories: electric heating forced-air drying ovens and vacuum drying ovens. They are widely used in fields such as medical and health, machinery, chemical industry, agriculture, and aerospace. The wide range of applications has led to a greater variety of drying ovens and a gradual differentiation in their structure.

[0003] Common drying ovens typically use hot air to directly blow into the loading area for rapid dehydration of items. Although the impact of hot air on items can be reduced by adjusting the size of the air outlet, it still has a significant impact on some raw materials that are in a powdery state when dried. While moist raw materials are not easily affected by strong winds, once the surface of the raw material is dried first, the powdery material is easily blown away by strong winds and drifts around in the loading area. Due to its small size and light weight, even if the air outlet is reduced in size, it is still impossible to prevent the powdery material from being blown away by the wind. Based on this, this solution provides a raw material constant temperature drying device to solve the above-mentioned problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, a raw material constant temperature drying device is provided. This technical solution solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A raw material constant temperature drying device includes a sealed box, inside which is a drying box. Several sets of carrier trays are stacked inside the drying box. A driving mechanism is provided at the bottom of the sealed box. The carrier tray includes a hollow carrier plate, on which a fixed seat is fixedly connected. A rotating cylinder is rotatably installed inside the fixed seat. A clamping plate is slidably connected inside the lower end of the rotating cylinder. A spring is fixedly connected between the clamping plate and the rotating cylinder. A slot is opened at the top of the rotating cylinder. Connecting rods are fixedly connected to both ends of the rotating cylinder. Several sets of stirring rods are fixedly connected to the connecting rods. The lowermost clamping plate is engaged with the driving mechanism.

[0007] Preferably, a fixing post is fixedly connected to each of the four corners at the lower end of the hollow carrier plate, and a retaining ring is fixedly connected to the hollow carrier plate on the outside of the connecting rod.

[0008] Preferably, the sealed box includes an outer box, an inner box is fixedly installed inside the outer box, a drive mechanism is fixedly installed on the bottom of the inner box, a guide rail is fixedly connected to the upper inner wall of the inner box, and a lifting plate is slidably connected inside the guide rail. The drying box is fixedly installed on the lifting plate. A box cover is rotatably installed on the upper rear side of the outer box, an air inlet pipe is fixedly installed on the lower right side of the outer box, and an air outlet pipe is fixedly installed on the lower left side of the outer box.

[0009] Preferably, the drying chamber includes a drying chamber body fixedly installed on a lifting plate. The interior of the drying chamber body is symmetrically and fixedly connected with partitions. Several sets of trays are stacked and placed between the partitions. Several sets of air inlet slots are opened at both the left and right ends of the drying chamber body. Air guide plates fixedly connected to the drying chamber body are provided on the outside of the air inlet slots.

[0010] Preferably, the drive mechanism includes a threaded rod rotatably mounted on the inner chamber, the upper end of the threaded rod penetrating into the interior of the drying chamber, and a slot 2 matching the card plate is provided at the top of the threaded rod. A sleeve is threadedly connected to the threaded rod, and a limit strip is fixedly connected to the sleeve. A first bevel gear is fixedly mounted on the threaded rod on the lower side of the sleeve. A servo motor is fixedly mounted on the inner chamber on the left side of the first bevel gear. A second bevel gear is fixedly connected to the output shaft of the servo motor, and the lower end of the second bevel gear meshes with the left end of the first bevel gear.

[0011] Preferably, an electric push rod is fixedly installed on the inner wall of the inner box on the right side of the sleeve, and the output shaft of the electric push rod is fixedly connected to a limit block.

[0012] Compared with the prior art, the present invention proposes a raw material constant temperature drying device, which has the following beneficial effects:

[0013] 1. This utility model is equipped with a carrier tray. The raw material to be dried is placed on the hollow carrier plate, the box cover is closed, and then hot air is introduced into the sealed box through the air inlet pipe. Under the action of the air guide plate and the air inlet groove, the hot air enters the hollow carrier plate, thereby drying the raw material placed on the hollow carrier plate. The hollow carrier plate also blocks the hot air, preventing the hot air from blowing directly on the raw material, thus ensuring that the raw material is not blown away by the hot air after drying.

[0014] 2. This utility model includes a driving mechanism. When several sets of trays are stacked, the clamping plate in the upper tray contacts the top of the rotating cylinder in the lower tray, and the clamping plate in the lowest tray abuts against the threaded rod of the driving mechanism. The top of the threaded rod in the driving mechanism has a second groove that matches the clamping plate. When the threaded rod rotates under the drive of the servo motor, when the second groove matches the clamping plate, the clamping plate is inserted into the second groove under the action of the spring. This allows the threaded rod to drive the lowest rotating cylinder. When the lower rotating cylinder rotates, and the first groove on its top matches the clamping plate of the upper tray, the clamping plate of the upper tray is inserted into the first groove under the action of the spring. This allows the rotating cylinder in the lower tray to drive the upper rotating cylinder, which in turn drives the stirring rods on the several sets of trays to turn the raw materials over, accelerating the drying efficiency and reducing the waiting time for drying.

[0015] 3. This utility model is equipped with an electric push rod and a limiting block. A sleeve is provided on the threaded rod. When the electric push rod does not drive the limiting block to block it, the sleeve rotates with the threaded rod. When the electric push rod is activated and drives the limiting block to block the sleeve in conjunction with the limiting strip, the sleeve can move on the threaded rod, thereby realizing the quick ejection of the drying box from the sealed box or its return to the sealed box, making it convenient for users to replace the trays inside the drying box.

[0029] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0030] Reference Figure 1-2 As shown, a raw material constant temperature drying device includes a sealed box 1, a drying box 2 is arranged inside the sealed box 1, several sets of carrier trays 3 are stacked inside the drying box 2, and a driving mechanism 4 is arranged at the bottom of the sealed box 1.

[0031] Reference Figure 5-6 As shown, the carrier plate 3 includes a hollow carrier plate 301, a fixed base 304 is fixedly connected to the hollow carrier plate 301, a rotating cylinder 305 is rotatably installed inside the fixed base 304, a clamping plate 306 is slidably connected to the lower end of the rotating cylinder 305, a spring 307 is fixedly connected between the clamping plate 306 and the rotating cylinder 305, a slot 308 is opened at the top of the rotating cylinder 305, a connecting rod 309 is fixedly connected to both ends of the rotating cylinder 305, a number of stirring rods 3010 are fixedly connected to the connecting rods 309, and the lowermost clamping plate 306 is engaged with the drive mechanism 4.

[0032] Furthermore: When several sets of carrier trays 3 are stacked, the clamping plate 306 in the upper carrier tray 3 will contact the top end of the rotating cylinder 305 in the lower carrier tray 3, and the clamping plate 305 in the lowermost carrier tray 3 will abut against the upper end of the threaded rod 401 of the drive mechanism 4. The top end of the threaded rod 401 in the drive mechanism 4 has a second clamping groove 407 that matches the clamping plate 306. When the threaded rod 401 rotates under the drive of the servo motor 403, when the second clamping groove 407 matches the clamping plate 306, the clamping plate 306 is inserted under the action of the spring 307. In slot 2 407, the threaded rod 401 can drive the bottom rotating cylinder 305. When the bottom rotating cylinder 305 rotates, the slot 1 308 on the top matches the plate 306 on the upper carrier plate 3. Under the action of the spring 307, the plate 305 on the upper carrier plate 3 will be inserted into the slot 1 308. This allows the rotating cylinder 305 in the bottom carrier plate 3 to drive the rotating cylinder 305 on the upper carrier plate 3, which in turn drives the stirring rods on several sets of carrier plates 3 to turn the raw materials over, thus accelerating the drying efficiency and reducing the waiting time for drying.

[0033] Reference Figure 5 As shown, specifically in this embodiment, a fixing post 302 is fixedly connected to each of the four corners of the lower end of the hollow carrier plate 301, and a retaining ring 303 fixedly connected to the hollow carrier plate 301 is provided on the outer side of the connecting rod 309.

[0034] Furthermore, the height of the fixed column 302 is greater than the height of the retaining ring 303 and the rotating cylinder 305 to avoid collisions.

[0035] Reference Figure 3 As shown, specifically in this embodiment, the sealed box 1 includes an outer box 101, an inner box 102 is fixedly installed inside the outer box 101, a drive mechanism 4 is fixedly installed on the bottom of the inner box 102, a guide rail 103 is fixedly connected to the upper inner wall of the inner box 102, and a lifting plate 104 is slidably connected inside the guide rail 103. The drying box 2 is fixedly installed on the lifting plate 104. A box cover 105 is rotatably installed on the upper rear side of the outer box 101, an air inlet pipe 106 is fixedly installed on the lower right side of the outer box 101, and an air outlet pipe 107 is fixedly installed on the lower left side of the outer box 101.

[0036] Reference Figure 4 and Figure 6 As shown, specifically in this embodiment, the drying chamber 2 includes a drying chamber body 201 fixedly installed on the lifting plate 104. The interior of the drying chamber body 201 is symmetrically and fixedly connected with partitions 202. Several sets of trays 3 are stacked and placed between the partitions 202. Several sets of air inlet slots 203 are opened at both the left and right ends of the drying chamber body 201. The outer side of the air inlet slots 203 is provided with air guide plates 204 fixedly connected to the drying chamber body 201.

[0037] Furthermore: The raw material to be dried is placed on the hollow carrier plate 301, the box cover 105 is closed, and then hot air is introduced into the sealed box 1 through the air inlet pipe 106. Under the action of the air guide plate 204 and the air inlet groove 203, the hot air enters the hollow carrier plate 301, thereby drying the raw material placed on the hollow carrier plate 301. The hollow carrier plate 301 also blocks the hot air, preventing the hot air from blowing directly on the raw material, thus ensuring that the raw material is not blown away by the hot air after drying.

[0038] Reference Figure 7 As shown, specifically in this embodiment, the drive mechanism 4 includes a threaded rod 401 rotatably mounted on the inner box 102. The upper end of the threaded rod 401 penetrates into the interior of the drying box 2, and the top end of the threaded rod 401 is provided with a slot 407 that matches the card plate 306. A sleeve 405 is threadedly connected to the threaded rod 401, and a limit strip 406 is fixedly connected to the sleeve 405. A first bevel gear 402 is fixedly mounted on the threaded rod 401 on the lower side of the sleeve 405. A servo motor 403 is fixedly mounted on the inner box 102 on the left side of the first bevel gear 402. A second bevel gear 404 is fixedly connected to the output shaft of the servo motor 403, and the lower end of the second bevel gear 404 meshes with the left end of the first bevel gear 402.

[0039] Furthermore: When the electric push rod 408 does not drive the limit block 409 to block it, the sleeve 405 rotates together with the threaded rod 401. The threaded rod 401 in the drive mechanism 4 has a slot 408 at the top end that matches the card plate 305. At this time, when the threaded rod 401 rotates under the drive of the servo motor 403, when the slot 408 matches the card plate 305, the card plate 306 is inserted into the slot 408 under the action of the spring 307, so that the threaded rod 401 can drive the bottom rotating cylinder 305.

[0040] Reference Figure 7 As shown, specifically in this embodiment, an electric push rod 408 is fixedly installed on the inner wall of the inner box 102 on the right side of the sleeve 405, and the output shaft of the electric push rod 408 is fixedly connected to a limit block 409.

[0041] Furthermore: When the electric push rod 408 is activated, the limit block 409, in conjunction with the limit strip 406, blocks the sleeve 405. At this time, the sleeve 405 can move on the threaded rod 401, thereby enabling the drying box 2 to be quickly pushed out of the sealing box 1 or stored back in the sealing box 1, making it convenient for the user to replace the tray 3 inside the drying box 2.

[0042] The working principle of this utility model is as follows: the raw material to be dried is placed on the hollow carrier plate 301, then multiple carrier trays 3 are stacked and the box cover 105 is closed. Then, hot air is introduced into the sealed box 1 through the air inlet pipe 106. Under the action of the air guide plate 204 and the air inlet groove 203, the hot air enters the hollow carrier plate 301, thereby drying the raw material placed on the hollow carrier plate 301. The hollow carrier plate 301 blocks the hot air, preventing the hot air from blowing directly on the raw material, thus ensuring that the raw material is not blown away by the hot air after drying.

[0043] When several sets of carrier trays 3 are stacked, the clamping plate 306 in the upper carrier tray 3 will contact the top end of the rotating cylinder 305 in the lower carrier tray 3, and the clamping plate 305 in the bottommost carrier tray 3 will abut against the upper end of the threaded rod 401 of the drive mechanism 4. The top end of the threaded rod 401 in the drive mechanism 4 has a second clamping groove 407 that matches the clamping plate 306. When the electric push rod 408 does not drive the limit block 409 to block it, when the threaded rod 401 rotates under the drive of the servo motor 403, the second clamping groove 407 matches the clamping plate 306. Under the action of the spring 307, the plate 306 is moved to the upper end of the rotating cylinder 306. When the card plate 306 is inserted into the card slot 407, the threaded rod 401 can drive the bottom rotating cylinder 305. When the bottom rotating cylinder 305 rotates, the card slot 308 on the top matches the card plate 306 on the upper carrier plate 3. Under the action of the spring 307, the card plate 305 on the upper carrier plate 3 will be inserted into the card slot 308. This allows the rotating cylinder 305 in the bottom carrier plate 3 to drive the rotating cylinder 305 on the upper carrier plate 3, which in turn drives the stirring rods on several sets of carrier plates 3 to turn the raw materials over, thus accelerating the drying efficiency and reducing the waiting time for drying.

[0044] When drying is complete, the electric push rod 408 is activated, and the limit block 409 works with the limit strip 406 to block the sleeve 405. At this time, the sleeve 405 can move on the threaded rod 401, thereby quickly pushing the drying box 2 out of the sealed box 1 to facilitate the user to replace the tray 3 inside the drying box 2.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
