Description

Technical Field

[0001] This invention relates to the field of heating system technology, and more particularly to a closed-loop heater system. Background Technology

[0002] In industries such as chemical, pharmaceutical, and food processing, closed-loop dryers are widely used in the dehydration and drying stages of production processes. Traditional dryer heater systems typically employ electric heating wires or infrared heating. However, due to uneven material distribution and temperature field within the dryer, the heating rate is slow and uneven, severely impacting the dryer's efficiency and processing capacity. Therefore, designing a novel heater system and control method to improve the heating efficiency and uniformity of the dryer is a crucial technical challenge. This necessitates the design of a closed-loop dryer heater system to address this issue. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the present invention provides a closed-loop heater system, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a closed-loop heater system, comprising a main body, a conveyor connected and installed on one side of the main body, a gas collecting hood fixedly installed on the top of the main body, a circulation body connected and installed on the side of the main body, and an exhaust pipe fixedly installed between the gas collecting hood and the circulation body, a feed inlet connected to the top of the conveyor, and a discharge valve fixedly installed at the bottom of the main body;

[0005] An electric feeding roller is installed inside the discharge valve. A drive shaft is connected and installed inside the conveyor. A push rod motor is connected and installed inside the conveyor. A connecting plate is connected to the output shaft of the push rod motor. A telescopic frame is fixedly installed on one side of the connecting plate. The telescopic frame is slidably connected to the conveyor. A first guide roller, a second guide roller, and a third guide roller are rotatably connected between the telescopic frames. A fourth guide roller is rotatably connected inside the main body. A conveyor belt is connected between the drive shaft, the first guide roller, the second guide roller, the third guide roller, and the fourth guide roller.

[0006] The main body is provided with a connecting seat, a first screen, a second screen, and a third screen. A fixed seat is fixedly installed between the connecting seats. A first drive motor is fixedly installed in the fixed seat, and an air chamber is opened in the fixed seat. The output shaft of the first drive motor is connected to a rotating seat, and a rotating shaft is fixedly installed on the top of the rotating seat. The first screen, the second screen, and the third screen are all rotatably connected to the rotating shaft. A first pressure roller, a second pressure roller, and a third pressure roller are connected and installed on the outside of the rotating shaft. The first pressure roller, the second pressure roller, and the third pressure roller are respectively connected to the first screen, the second screen, and the third screen. The first pressure roller is connected to a first rotating wheel through the rotating shaft. The second pressure roller is connected to a second rotating wheel through the rotating shaft. The third pressure roller is connected to a third rotating wheel through the rotating shaft. A fourth rotating wheel is rotatably connected in the rotating seat. A transmission belt is connected between the first rotating wheel, the second rotating wheel, the third rotating wheel, and the fourth rotating wheel. A second drive motor is connected and installed on one side of the fourth rotating wheel.

[0007] The circulating body is equipped with a heat exchanger, a filter bag, a regenerator, and a fan, and one side of the bottom of the circulating body is connected to the main body.

[0008] As a preferred embodiment of the present invention, the electric feeding rollers are in two sets, with the outer rings made of rubber material and connected on the outside. This can stabilize the material conveying process while providing a certain degree of sealing for the conveyor and preventing heat loss.

[0009] As a preferred embodiment of the present invention, the main body is provided with a feeding chamber and a heating chamber. The feeding chamber adopts a square structure design, and the heating chamber adopts a circular structure design. The diameter of the heating chamber is larger than the diagonal length of the feeding chamber, which enables the conveyor belt to accurately drop the material into the heating chamber when feeding.

[0010] As a preferred embodiment of the present invention, the top of the air chamber and the connecting seat are provided with a number of micro ventilation holes, which facilitates heat transfer while preventing materials from entering the conveyor belt and the interior of the air chamber.

[0011] As a preferred embodiment of the present invention, a through groove is provided at the connection between the feeding chamber and the conveyor, and a scraper is fixedly installed in the through groove. The top of the scraper adopts an inclined structure design and is connected to the bottom of the conveyor belt. The side of the scraper is flush with the feeding chamber and is used to scrape off the material attached to the conveyor belt so that it can completely enter the heating chamber.

[0012] As a preferred embodiment of the present invention, the connecting seats are in four groups, two in each group, and arranged in a ring array on the outside of the fixed seat. The top of the connecting seats adopts a triangular structure design to avoid material accumulation. One group of connecting seats has a through hole, and the two ends of the through hole are connected to the circulation body and the air chamber respectively to facilitate heat circulation and heating.

[0013] As a preferred embodiment of the present invention, baffles and vibrators are respectively provided at the top and bottom of the first screen, the second screen, and the third screen to facilitate screening. The diameter of the screen holes in the first screen, the second screen, and the third screen decreases step by step. The first pressure roller, the second pressure roller, and the third pressure roller are all composed of a protective frame and a pressure roller. The protective frame is fixedly connected to the rotating shaft and adopts a triangular structure design at the top. The pressure roller is rotatably connected to the rotating shaft, and the diameter of the pressure roller in the first pressure roller, the second pressure roller, and the third pressure roller decreases step by step, thereby realizing the step-by-step crushing of materials and accelerating the heating efficiency.

[0014] The beneficial effects of this invention are:

[0015] The conveyor belt in the conveyor can continuously transport materials, and the conveyor belt can extend and retract in conjunction with the push rod motor, connecting plate and telescopic frame, so that the materials can be evenly spread in the heating chamber. The electric feeding roller can also play a certain sealing role while transporting materials to prevent heat loss, thus enabling continuous feeding without stopping the machine to add materials, which greatly speeds up the work efficiency.

[0016] The first drive motor controls the rotation of the shaft, causing the first, second, and third pressure rollers to perform circular motion at the top of the first, second, and third screens, thereby agitating the material. Furthermore, the first, second, and third pressure rollers can also be controlled by the second drive motor to rotate, crushing the material at the top of the first, second, and third screens, gradually pulverizing it, increasing the contact area with the heat flow, thus improving the heating effect, and working in conjunction with the first, second, and third screens to screen the material.

[0017] The internal heat is circulated by a fan, and the interior is continuously heated by a heat exchanger and a regenerator. A filter bag is used to absorb the moisture generated after heating, thereby improving heating efficiency. Attached Figure Description

The main body 1 is provided with a connecting seat 19, a first screen 21, a second screen 22, and a third screen 23. A fixed seat 20 is fixedly installed between the connecting seats 19. A first drive motor 24 is fixedly installed in the fixed seat 20, and an air chamber 25 is opened in the fixed seat 20. There are four sets of connecting seats 19, two in each set, which are distributed in a ring array on the outside of the fixed seat 20. The top of the connecting seat 19 adopts a triangular structure design to avoid material accumulation, and one set of connecting seats 19 has an opening The device has through holes, with both ends connected to the circulation body 4 and the air chamber 25 respectively, facilitating heat circulation and heating. Several micro-vents are provided at the top of the air chamber 25 and inside the connecting seat 19, facilitating heat transfer while preventing material from entering the conveyor belt 17 and the air chamber 25. The output shaft of the first drive motor 24 is connected to a rotating seat 26, and a rotating shaft 27 is fixedly installed on the top of the rotating seat 26. The first screen 21, the second screen 22, and the third screen 23 are all rotatably connected to the rotating shaft 27. A first pressure roller 28, a second pressure roller 29, and a third pressure roller 30 are connected and installed on the outside of the rotating shaft 27, and these rollers are respectively connected to the first screen 21, the second screen 22, and the third screen 23.The top and bottom of the first screen 21, the second screen 22, and the third screen 23 are respectively equipped with baffles and vibrators to facilitate screening. The screen aperture diameters within the first screen 21, the second screen 22, and the third screen 23 decrease progressively. The first pressure roller 28, the second pressure roller 29, and the third pressure roller 30 are all composed of a protective frame and pressure rollers. The protective frame is fixedly connected to the rotating shaft 27 and features a triangular structure at its top. The pressure rollers are rotatably connected to the rotating shaft 27, and the diameters of the pressure rollers within the first pressure roller 28, the second pressure roller 29, and the third pressure roller 30 decrease progressively, thereby achieving progressive crushing of the material and accelerating the process. For heating efficiency, the first pressure roller 28 is connected to the first rotating wheel 31 via a rotating shaft 27; the second pressure roller 29 is connected to the second rotating wheel 32 via a rotating shaft 27; the third pressure roller 30 is connected to the third rotating wheel 33 via a rotating shaft 27; a fourth rotating wheel 34 is rotatably connected inside the rotating seat 26; and a transmission belt 35 connects the first rotating wheel 31, the second rotating wheel 32, the third rotating wheel 33, and the fourth rotating wheel 34.

[0027] Working principle: During operation, the material to be heated is poured into the feed inlet 6, and then the electric feeding roller 8 rotates to continuously convey the material to the top of the conveyor belt 17. At the same time, the drive shaft 9 rotates continuously, controlling the conveyor belt 17 to move the material towards the feeding chamber of the main body 1. The push rod motor 10 continuously extends and retracts, shortening the distance between the drive shaft 9 and the first guide roller 13, and lengthening the distance between the third guide roller 15 and the fourth guide roller 16. This causes the conveyor belt 17 to continuously extend and retract within the feeding chamber, evenly spreading the material above the first screen 21. Simultaneously, the first drive motor 24 controls the first pressure roller 28 to rotate on top of the first screen 21 to stir the material, and the second drive motor 36 drives the first pressure roller 28 through the transmission belt 35. The material is crushed by rollers 28, 29, and 30, allowing it to pass through the first screen 21 and accumulate on the second screen 22. This process continues as the material is crushed step by step by rollers 28, 29, and 30, passing through the first screen 21, second screen 22, and third screen 23 before falling onto the fixed base 20. Simultaneously, the rotating shaft 27 and the regenerator 39 work continuously to heat the interior. The fan 40 inputs the heat flow into the air chamber 25, which then flows upward. The material is heated sequentially through the third screen 23, second screen 22, and first screen 21, and then re-enters the circulation body 4 through the exhaust pipe 5 for further heating. Meanwhile, the filter bag 38 absorbs the moisture generated after heating, thus ensuring continuous heating.
