Description

Technical Field

[0001] This utility model provides a continuous thiazoline dryer, belonging to the technical field of thiazoline drying equipment. Background Technology

[0002] Thiadiazon is a phenylurea plant growth regulator with strong cytokinin activity and is widely used in agriculture. It promotes plant growth, increases crop yield, and enhances crop resistance, playing a vital role in cotton defoliation and fruit tree fruit setting. Drying is a crucial step in the production of thiamethoxam. The purpose of drying is to remove moisture from the thiamethoxam to ensure its quality and stability, extend its shelf life, and also facilitate subsequent packaging, transportation, and use.

[0003] During production, transportation, or storage, thiamethoxam may clump due to moisture, compression, or other factors. When these clumps of thiamethoxam enter the dryer, they affect the uniformity of drying. The moisture inside the clumps is difficult to evaporate quickly, leading to some thiamethoxam being over-dried while the remaining thiamethoxam inside the clumps is under-dried, thus affecting the overall quality and performance of the product.

[0004] Therefore, thiamethoxam often requires pre-crushing before drying to ensure that the particle size and uniformity of the material meet the drying requirements. However, existing pretreatment devices are often separate from the dryer, requiring the thiamethoxam to be crushed before being transferred to the dryer, which is cumbersome. Furthermore, thiamethoxam residue easily remains on the inner wall of the pretreatment device after processing. This is because thiamethoxam has a certain degree of stickiness and easily adheres to the inner wall of the pretreatment device. Cleaning these residues often involves disassembling the device, which is very inconvenient. Therefore, there is an urgent need to develop a new type of continuous thiamethoxam dryer and pretreatment device to solve these problems. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing pretreatment devices for thiamethoxam are set up separately from the dryer, and the thiamethoxam is transferred after pretreatment, which is cumbersome to operate; at the same time, thiamethoxam tends to adhere to the pretreatment device, making cleaning inconvenient.

[0006] In order to solve the above problems, the present invention proposes the following technical solution: a continuous thiamethoxam dryer, comprising a drying cylinder, an end cover, and a support, wherein the end cover is disposed above the drying cylinder, a feed pipe is connected to the end cover, and a discharge hole is provided at the bottom of the drying cylinder;

[0007] The end cap is slidably mounted above the drying cylinder, and a pre-drying chamber located inside the drying cylinder is fixedly connected below the end cap; the pre-drying chamber has an open bottom, and a rotating plate that blocks the bottom of the pre-drying chamber is rotatably connected inside the drying cylinder; it also includes:

[0008] A crushing assembly and a scraper; the crushing assembly capable of crushing agglomerated thiamethoxam is rotatably disposed inside a pre-drying chamber; the scraper is located inside the pre-drying chamber and is in contact with the inner wall of the pre-drying chamber.

[0009] As an improvement, a rotating rod is horizontally rotatably connected inside the drying cylinder, and the rotating rod is fixedly connected to the rotating plate; a rotating motor is provided on the outer wall of the drying cylinder, and the output end of the rotating motor is fixedly connected to the rotating rod.

[0010] As an improvement, the bracket is fixedly installed on the ground and has an L-shaped plate structure; the bracket is equipped with an electric telescopic rod, and the working end of the electric telescopic rod is fixedly connected to the end cap.

[0011] As an improvement, the crushing assembly includes a rotating shaft and crushing rods; the rotating shaft is rotatably disposed inside a pre-drying chamber, and several crushing rods are fixedly connected to the rotating shaft; a crushing motor is disposed on the end cover, and the output shaft of the crushing motor is fixedly connected to the rotating shaft.

[0012] As an improvement, two connecting rods are fixedly installed inside the bracket, and the connecting rods pass through the end cover and are fixedly connected to the scraper; the end cover is slidably installed relative to the connecting rods.

[0013] As an improvement, the scraper is annular, and the position where the scraper contacts the pre-drying oven is set in a sharp wedge shape.

[0014] As an improvement, a hot air blower is provided on the support, and the working end of the hot air blower is connected to two hot air pipes, which are respectively connected to the drying cylinder and the pre-drying box.

[0015] The beneficial effects of this utility model are:

[0016] 1. A pre-drying chamber is fixedly connected below the end cap and located inside the drying cylinder. The crushing component is rotatably positioned inside the pre-drying chamber. By setting up a pre-drying chamber inside the drying cylinder, the agglomerated thiamethoxam can be crushed and pre-treated, and preliminary drying can be performed simultaneously. The pre-treated thiamethoxam can be immediately introduced into the drying cylinder, reducing the need for thiamethoxam transfer operations.

[0017] 2. By setting up interconnected pre-drying chambers and rotating plates, and utilizing sliding end caps to drive the pre-drying chambers upward, the pre-drying chambers are separated from the rotating plates and removed from the drying cylinder. This allows for quick separation of the pre-drying chambers from the drying cylinder, facilitating cleaning. Simultaneously, the scraper can scrape and clean the inner wall of the pre-drying chamber during separation, improving the cleaning effect. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] according to Figure 1-5 As shown: This utility model provides a continuous thiamethoxam dryer: including a drying cylinder 1, an end cover 3, and a support 2. The end cover 3 is located above the drying cylinder 1, and a feed pipe 5 is connected to the end cover 3. The bottom of the drying cylinder 1 is provided with a discharge hole 6.

[0026] like Figure 3 As shown, the end cap 3 is slidably mounted above the drying cylinder 1, and a pre-drying chamber 12 located inside the drying cylinder 1 is fixedly connected below the end cap 3; the support 2 is fixedly mounted on the ground, and the support 2 has an L-shaped plate structure; an electric telescopic rod 10 is mounted on the support 2, and the working end of the electric telescopic rod 10 is fixedly connected to the end cap 3; by setting the electric telescopic rod 10, the opening and closing of the end cap 3 can be easily controlled, and the pre-drying chamber 12 fixedly connected to the end cap 3 can be moved out of the drying cylinder 1 for easy cleaning later.

[0027] like Figure 4 As shown, the pre-drying chamber 12 has an open bottom structure, and a rotating plate 7 that blocks the bottom of the pre-drying chamber 12 is rotatably connected inside the drying cylinder 1; a rotating rod 9 is horizontally rotatably connected inside the drying cylinder 1, and the rotating rod 9 is fixedly connected to the rotating plate 7; a rotating motor 8 is provided on the outer wall of the drying cylinder 1, and the output end of the rotating motor 8 is fixedly connected to the rotating rod 9; by providing the rotating motor 8, the rotation control of the rotating plate 7 can be conveniently achieved, and when the pre-drying chamber 12 is separated from the rotating plate 7, the thiamethoxam on the rotating plate 7 can be quickly dropped into the bottom of the drying cylinder 1.

[0028] like Figure 4 As shown, a crushing assembly capable of breaking up agglomerated thiamethoxam is rotatably mounted inside a pre-drying chamber 12. The crushing assembly includes a rotating shaft 15 and crushing rods 16. The rotating shaft 15 is rotatably mounted inside the pre-drying chamber 12, and several crushing rods 16 are fixedly connected to the rotating shaft 15. A crushing motor 13 is mounted on the end cover 3, and the output shaft of the crushing motor 13 is fixedly connected to the rotating shaft 15. By providing the crushing motor 13, power can be supplied to the rotation of the crushing rods 16, thereby crushing the agglomerated thiamethoxam.

[0029] like Figure 4 , 5 As shown, the scraper 17 is located inside the pre-drying chamber 12, and the scraper 17 is in contact with the inner wall of the pre-drying chamber 12.

[0030] Two connecting rods 14 are fixedly installed inside the bracket 2. The connecting rods 14 pass through the end cover 3 and are fixedly connected to the scraper 17; the end cover 3 is slidably disposed relative to the connecting rods 14. Because the scraper 17 is fixedly disposed, when the end cover 3 drives the pre-drying chamber 12 to slide, the scraper 17 can scrape the inner wall of the pre-drying chamber 12, thereby reducing the amount of thiamethoxam remaining on the inner wall of the pre-drying chamber 12. The scraper 17 is annular, and the position where the scraper 17 contacts the pre-drying chamber 12 is set in a sharp wedge shape, which can improve the scraping effect.

[0031] like Figure 1 , 5 As shown, a hot air blower 4 is installed on the support 2. The working end of the hot air blower 4 is connected to two hot air pipes 11, and the two hot air pipes 11 are respectively connected to the drying cylinder 1 and the pre-drying box 12. By setting up the hot air blower 4, hot air can be introduced into the pre-drying box 12 to pre-dry the normally crushed thiamethoxam, and hot air can also be introduced into the drying cylinder 1 to ensure continuous drying of thiamethoxam.

[0032] The principle of this utility model

[0033] like Figure 1 , 2 As shown, when using this application, the rotating plate 7 normally blocks the bottom of the pre-drying box 12, forming a relatively closed structure; the agglomerated thiamethoxam is added into the pre-drying box 12 through the feed pipe 5, the crushing motor 13 is started, and the crushing rod 16 is used to crush the agglomerated thiamethoxam. At the same time, the hot air blower 4 is started, and hot air is delivered into the pre-drying box 12 through the hot air pipe 11 to pre-dry the thiamethoxam being crushed.

[0034] like Figure 3 , 4As shown, after crushing, the electric telescopic rod 10 is activated, driving the end cover 3 and the pre-drying chamber 12 to move upwards until the pre-drying chamber 12 detaches from the drying cylinder 1. During the upward movement of the pre-drying chamber 12, since the scraper 17 remains stationary, the pre-drying chamber 12 can slide relative to the scraper 17, thereby scraping off the thiamethoxam adhering to the inner wall of the pre-drying chamber 12 and dropping it onto the rotating plate 7. After the pre-drying chamber 12 moves upwards and separates from the rotating plate 7, the rotating motor 8 is activated to drive the rotating plate 7 to rotate. The crushed thiamethoxam and the thiamethoxam scraped off from the inner wall of the pre-drying chamber 12 located on the rotating plate 7 can fall directly into the bottom of the drying cylinder 1 for secondary continuous drying. The entire process facilitates the crushing and pre-drying of agglomerated thiamethoxam. After crushing, it not only quickly guides the thiamethoxam to the bottom of the drying cylinder 1 for secondary drying, but also quickly separates the pre-drying chamber 12 from the drying cylinder 1, thus facilitating subsequent cleaning.

[0035] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
