Description

Technical Field

[0001] This utility model relates to the field of filling device technology, and in particular to a high-efficiency filling device for chloromethylpyridine hydrochloride. Background Technology

[0002] Chloromethylpyridine hydrochloride is a salt compound formed by the chloromethyl substituent on the pyridine ring and hydrochloric acid. It has a variety of isomers (such as 2-, 3-, and 4-substituent positions) and is widely used in the fields of pesticides, pharmaceuticals, and materials. During the production process, the raw materials need to be filled into specific containers for storage using a filling device.

[0003] Existing filling mechanisms typically use screw conveyors for feeding and filling. During filling, the friction between the raw material and the conveying screw easily generates heat, causing the material to adhere to the screw and block the feeding pipe. This results in slow filling speed and poor performance. Furthermore, some material inside the tank adheres to the inner wall during filling, leading to material residue and poor overall performance. To address these issues, we propose a high-efficiency filling device for chloromethylpyridine hydrochloride. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a high-efficiency filling device for chloromethylpyridine hydrochloride.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency filling device for chloromethylpyridine hydrochloride is designed, including a tank body, which is fixed on a base by a mounting bracket. A belt conveyor is installed on the top of the base, and a discharge pipe is opened at the bottom of the tank body, with the belt conveyor located below the discharge pipe.

[0006] The top of the tank is fitted with a top cover, and the bottom of the top cover is rotatably connected to a rotating shaft. The top of the rotating shaft is connected to a drive motor, which is fixed to the top of the top cover. The other end of the rotating shaft is rotatably connected to the end of the discharge pipe, and a discharge port is opened on one side of the bottom of the discharge pipe.

[0007] A first helical blade is installed on the side of the rotating shaft, and a second helical blade is provided below the first helical blade. The second helical blade is fixed on the side of the rotating shaft and extends into the discharge pipe.

[0008] Several spiral scrapers are installed inside the tank. Each spiral scraper is fixed to the side of the rotating shaft by a connecting rod, and one side of the spiral scraper is fitted with the inner wall of the tank with a clearance.

[0009] Two connecting rings are symmetrically installed on the side of the discharge pipe. Two cooling shrouds are provided between the two connecting rings. Each cooling shroud is arc-shaped and the ends of the two cooling shrouds abut each other, forming a receiving space between them. The discharge port is located in this space.

[0010] Each cooling shroud has an internal mounting plate, and at least one cooling fin is mounted on the side of each mounting plate. The cold end of the cooling fin extends through the mounting plate to one side of the discharge pipe. There are mounting slots on both sides of the discharge pipe, and each mounting slot has a snap-action temperature control switch installed inside. The snap-action temperature control switch is connected to the cooling fin via a wire.

[0011] Preferably, the first helical blade is located at the bottom of the tank, and the first helical blade is fitted with the inner wall of the tank with a clearance.

[0012] Preferably, the bottom of the first helical blade is connected to the top of the second helical blade.

[0013] Preferably, skirts are provided on the adjacent sides of both cooling shrouds, and adjacent skirts are fastened together by bolts.

[0014] Preferably, each cooling cover has a rim installed at both ends, and when the two cooling covers come into contact with each other on their adjacent sides, the side of the rim is sealed to the side of the adjacent connecting ring.

[0015] Preferably, there is a gap between the cold end of the cooling element and the side of the discharge pipe, and a gap between the hot end of the cooling element and the inner wall of the cooling shroud.

[0016] Preferably, each cooling shroud has an air inlet installed on its side, one end of which is connected to the interior of the cooling shroud, and each air inlet has a fan installed inside, which is connected to a snap-action temperature control switch via a wire.

[0017] Each cooling shroud has a heat dissipation slot on its side, which is connected to the inside of the cooling shroud.

[0018] Preferably, a feed pipe is installed on the top of the tank.

[0019] The design scheme proposed in this utility model has the following beneficial effects in application:

[0020] 1. The cooling element can cool down the raw material in the discharge pipe, preventing the raw material from crystallizing due to excessive temperature during conveying and filling. This prevents the raw material from crystallizing and adhering to the second spiral blade, thus blocking the discharge pipe and improving the performance.

[0021] 2. By installing a spiral scraper inside the tank, the spiral scraper can rotate with the shaft during filling to scrape off the raw material adhering to the inside of the tank, avoiding a large amount of raw material residue in the tank and improving the use effect.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figures 1-4 A high-efficiency filling device for chloromethylpyridine hydrochloride includes a tank 5, which is fixed to a base 9 by a mounting bracket 1. A belt conveyor 8 is installed on the top of the base 9, and a discharge pipe 18 is provided at the bottom of the tank 5. The belt conveyor 8 is located below the discharge pipe 18. In actual use, the belt conveyor 8 can transport the container to the bottom of the discharge pipe 18, and the raw material in the tank 5 can be discharged into the container for filling through the discharge pipe 18.

[0030] like Figure 1 As shown, a feed pipe 22 is installed on the top of the tank 5, through which workers can transport raw materials into the tank 5 for filling.

[0031] It should be noted that when conveying containers, the belt conveyor 8 can position the containers using externally installed positioning mechanisms such as laser positioning or infrared positioning, so that the containers will not shift during filling.

[0032] like Figure 1As shown, a top cover 6 is installed on the top of the tank 5. A rotating shaft 13 is rotatably connected to the bottom of the top cover 6. A drive motor 7 is connected to the top of the rotating shaft 13. The drive motor 7 is fixed to the top of the top cover 6. The other end of the rotating shaft 13 is rotatably connected to the end of the discharge pipe 18. A discharge port 23 is opened on one side of the bottom of the discharge pipe 18. A first spiral blade 10 is installed on the side of the rotating shaft 13. A second spiral blade 11 is provided below the first spiral blade 10. The second spiral blade 11 is fixed on the side of the rotating shaft 13 and extends into the discharge pipe 18. In actual use, the drive motor 7 can drive the rotating shaft 13 to rotate, which in turn can drive the first spiral blade 10 and the second spiral blade 11 to rotate, transporting the raw materials in the tank 5 to the discharge port 23 and discharging them into the container for collection.

[0033] like Figure 2 and Figure 4 As shown, the first spiral blade 10 is the bottom of the tank body 5, and the first spiral blade 10 is fitted with the inner wall of the tank body 5 with a clearance. The bottom of the first spiral blade 10 is connected to the top of the second spiral blade 11. In this way, the first spiral blade 10 can transport the raw material to the second spiral blade 11, and then the second spiral blade 11 discharges the raw material through the discharge port 23.

[0034] like Figure 2 and Figure 4 As shown, several spiral scrapers 12 are provided inside the tank body 5. Each spiral scraper 12 is fixed to the side of the rotating shaft 13 by a connecting rod, and one side of the spiral scraper 12 is in clearance fit with the inner wall of the tank body 5. When the rotating shaft 13 rotates, it will drive the spiral scraper 12 to rotate synchronously. During the rotation process, the spiral scraper 12 will scrape off the raw material remaining on the inner wall of the tank body 5 and discharge it from the tank body 5 through the first spiral blade 10 and the second spiral blade 11, so as to avoid the raw material adhering to the inner wall of the tank body 5 and improve the use effect.

[0035] like Figure 1 and Figure 3 As shown, two connecting rings 2 are symmetrically installed on the side of the discharge pipe 18. Two cooling covers 4 are provided between the two connecting rings 2. Each cooling cover 4 is arc-shaped, and the ends of the two cooling covers 4 abut against each other, forming a receiving space. The discharge port 23 is located in this space. The cooling covers 4 can wrap around the side of the discharge pipe 18, which can fully cool the inside of the discharge pipe 18, prevent the raw material from crystallizing due to excessive temperature during filling, and improve the use effect.

[0036] like Figure 1 and Figure 3 As shown, skirts 16 are extended from the adjacent sides of the two cooling covers 4. The two adjacent skirts 16 are fastened together by bolts, which can fix the two cooling covers 4 together and make them secure.

[0037] It should be noted that each cooling cover 4 has a rim 17 installed at both ends. When two cooling covers 4 are close together, the side of the rim 17 is sealed to the side of the adjacent connecting ring 2. This can isolate the space between the cooling cover 4 and the discharge pipe 18 from the external environment, thereby reducing the impact of the external temperature on the cooling of the cooling element 15.

[0038] like Figure 3 and Figure 5 As shown, each cooling shroud 4 has an installation plate 14 installed inside. At least one cooling chip 15 is installed on the side of each installation plate 14. The cold end of the cooling chip 15 extends through the installation plate 14 to one side of the discharge pipe 18. Installation slots 19 are provided on both sides of the discharge pipe 18. A snap-action temperature control switch 20 is installed inside each installation slot 19. The snap-action temperature control switch 20 is connected to the cooling chip 15 through a wire. In actual use, the cold end of the cooling chip 15 cools the raw material inside the discharge pipe 18 and detects it through the snap-action temperature control switch 20. When the raw material temperature is higher than the preset value, the snap-action temperature control switch 20 closes, the cooling chip 15 works, and the raw material is cooled. When the temperature reaches the preset value, the snap-action temperature control switch 20 opens, and the cooling chip 15 stops working.

[0039] like Figure 3 and Figure 5 As shown, each cooling cover 4 has an air inlet 3 installed on its side. One end of the air inlet 3 is connected to the interior of the cooling cover 4, and a fan 21 is installed inside each air inlet 3. The fan 21 is connected to the snap-action temperature control switch 20 through a wire. Each cooling cover 4 has a heat dissipation slot 24 on its side, which is connected to the interior of the cooling cover 4. In actual use, when the cooling chip 15 is cooling, the snap-action temperature control switch 20 is closed, the fan 21 works, and blows the outside air to the hot end of the cooling chip 15 to cool the hot end of the cooling chip 15. Then the air is discharged through the heat dissipation slot 24.

[0040] Specifically, in use, the container is conveyed to the bottom of the discharge pipe 18 by the belt conveyor 8. The worker feeds the raw material into the tank 5 through the feed pipe 22. Then, the drive motor 7 is activated, driving the rotating shaft 13 to rotate. The rotating shaft 13 simultaneously drives the first spiral blade 10 and the second spiral blade 11 to rotate, conveying the raw material in the tank 5 into the discharge pipe 18, and then discharging it into the container through the discharge port 23 for filling. At the same time, the rotating shaft 13 also drives the spiral scraper 12 to rotate, and the spiral scraper 12 removes the residue in the tank 5. The raw material on the inner wall is scraped off to avoid a large amount of raw material remaining inside the tank 5, thus improving the performance. During the discharge process, when the internal temperature of the discharge pipe 18 is higher than the preset value, the snap-on temperature control switch 20 closes, and the cooling plate 15 and fan 21 work. The cold end of the cooling plate 15 cools down the raw material inside the discharge pipe 18 to prevent the raw material from heating up and crystallizing during the friction with the second spiral blade 11, and blocks the discharge pipe 18. Then the fan 21 blows the outside air to the hot end of the cooling plate 15 to cool down the hot end of the cooling plate 15. After that, the air is discharged through the heat dissipation groove 24.

[0041] Furthermore, such as Figure 5 As shown, there is a gap between the cold end of the cooling chip 15 and the side of the discharge pipe 18, and there is a gap between the hot end of the cooling chip 15 and the inner wall of the cooling cover 4, so that the cooling chip 15 will not collide with the discharge pipe 18 during installation.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
