Description

Technical Field

[0001] This utility model relates to the technical field of drying equipment for high-viscosity and high-moisture materials, specifically a preheating tube bundle drying machine for high-viscosity and high-moisture materials. Background Technology

[0002] Currently, it is quite difficult to dry high-viscosity, high-moisture materials using tube bundle dryers. This is because if high-moisture, high-viscosity materials are directly fed into the tube bundle dryer, the tubes will stick together, and the equipment will be unable to continue operating after a few hours. Utility Model Content

[0003] The purpose of this invention is to provide an integrated preheating and drying machine for high-viscosity and high-moisture materials, in order to solve the problems mentioned in the background art, such as the tubes sticking when high-moisture and high-viscosity materials are directly fed into the tubes, causing the equipment to be unable to continue operating after a few hours.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a preheating tube bundle drying integrated machine for high-viscosity and high-moisture materials, comprising a preheating tube bundle integrated machine body, the outer shell of the preheating tube bundle integrated machine body being an integrally formed tubular shape, a rotary drive device being provided below the preheating tube bundle integrated machine body, the preheating tube bundle integrated machine body including a heating tube bundle and a preheating section tube bundle, a feeding screw and a gas-fired hot air furnace being provided at the fixed feeding end on the outer side of the preheating section tube bundle, a preheating section lifting plate being provided on the inner wall of the preheating section tube bundle, a heating tube bundle being provided inside the heating tube bundle, a hot section lifting plate being provided on the inner wall of the heating tube bundle on the outer side of the heating tube bundle, and a waste liquid and waste gas discharge structure being provided at the fixed discharge end on the outer side of the heating tube bundle.

[0005] The rotary drive device includes a large gear ring and a small gear. The large gear ring is fitted and fixed in the middle of the preheating tube bundle integrated machine body, and the small gear is located on the outside of the outer gear ring and cooperates with the outer gear ring. The small gear is driven by a motor.

[0006] A speed reducer is installed between the motor and the pinion.

[0007] Rollers are installed on the main body of the preheating tube bundle integrated machine on both sides of the large gear ring.

[0008] Sealing devices are installed at the fixed feed end and fixed discharge end at both ends of the preheating tube bundle integrated machine body.

[0009] The waste liquid and waste gas discharge structure includes a rotary joint with two flow channels for steam inlet and water outlet. The rotary joint with two flow channels for steam inlet and water outlet is equipped with a condensate outlet pipe and a steam inlet.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] The design of the heating tube bundle and preheating section tube bundle in this invention enables the tube bundle dryer to perform both preheating and drying functions. Preheating before drying reduces some of the moisture content in high-viscosity, high-moisture materials, thereby reducing operating power and costs, and broadening the application of the tube bundle dryer. It can also effectively consume high-viscosity byproducts, turning waste into treasure. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the overall structure of this utility model.

[0013] In the above attached figures, there is a rotary joint for two flow channels (steam inlet and water outlet), condensate outlet 1-1, steam inlet 1-2, condensate outlet pipe 1-3, fixed discharge end 2, sealing device 3, heating tube bundle 4, heating lifting plate 5, support roller 6, large gear ring 7, small gear 8, reducer 9, motor 10, preheating section lifting plate 11, preheating tube bundle integrated machine body 13, fixed feed end 14, gas-fired hot air furnace 16, and feed screw 17. Detailed Implementation

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] like Figure 1 As shown, a preheating tube bundle drying machine for high-viscosity, high-moisture materials includes a preheating tube bundle machine body 13. The outer shell of the preheating tube bundle machine body 13 is an integrally formed tubular shape. A rotary drive device is arranged below the preheating tube bundle machine body 13 to drive the preheating tube bundle machine body 13 to rotate. The rotary drive device includes a large gear ring 7 and a small gear 8. The large gear ring 7 is sleeved and fixed in the middle of the preheating tube bundle machine body 13. The small gear 8 is arranged outside the outer gear ring and cooperates with the outer gear ring. The small gear 8 is driven by a motor 10. When the motor 10 is started, the motor 10 drives the small gear 8 to rotate. The small gear 8 drives the preheating tube bundle machine body 13 to rotate through cooperation with the outer gear ring. The material inside the preheating tube bundle machine body 13 rotates with the preheating tube bundle machine body 13.

[0016] A speed reducer 9 is installed between the motor 10 and the pinion 8; the output stability of the motor 10 is controlled by the speed reducer 9.

[0017] The preheating tube bundle integrated machine body 13 on both sides of the large gear ring 7 is provided with support rollers 6. The preheating tube bundle integrated machine body 13 and the support rollers 6 are rotatably mounted on the support, and the support rollers 6 support the preheating tube bundle integrated machine body 13.

[0018] The main body 13 of the preheating tube bundle integrated machine includes a heating tube bundle and a preheating section tube bundle. The fixed feeding end on the outside of the preheating section tube bundle is equipped with a feeding screw 17 and a gas-fired hot air furnace 16. The feeding screw 17 is a feeding structure that feeds the material to be dried into the preheating section tube bundle of the preheating tube bundle integrated machine. The gas-fired hot air furnace 16 provides hot air into the preheating section tube bundle to process the material in the preheating section tube bundle. The inner wall of the preheating section tube bundle is equipped with a preheating section lifting plate 11, which ensures that the preheated material is in full contact with the hot air.

[0019] Heating tube bundle 4 is installed inside the heating tube bundle. The material entering the heating tube bundle is heated and dried through the heating tube bundle 4. A hot section lifting plate is installed on the inner wall of the heating tube bundle outside the heating tube bundle. The hot section lifting plate ensures that the material being heated and dried is in full contact with the heating tube bundle.

[0020] The fixed discharge end 2 on the outside of the heating tube bundle is equipped with a waste liquid and waste gas discharge structure. The waste liquid and waste gas generated are discharged through the waste liquid and waste gas discharge structure. The waste liquid and waste gas discharge structure includes a two-channel rotary joint 1 with steam inlet and water outlet. The two-channel rotary joint 1 with steam inlet and water outlet is equipped with a condensate outlet pipe 1-3 and a steam inlet 1-2. The dry and wet gas generated by the material is discharged as waste liquid from the condensate outlet 1-1 through the condensate outlet pipe 1-3, or as waste gas from the gas outlet. External heating steam enters the heating tube bundle 4 through the steam inlet 1-2 for heating.

[0021] Sealing devices 3 are respectively installed at the fixed feed end and fixed discharge end 2 at both ends of the preheating tube bundle integrated machine body 13 to prevent material from overflowing from both ends of the preheating tube bundle integrated machine body 13.

[0022] The working process of this utility model is as follows: Material enters the equipment (i.e., the preheating tube bundle integrated machine body 13) through the feeding screw 17. Hot air supplied by the gas-fired hot air furnace 16 enters the equipment. The material is lifted by the preheating lifting plate and fully contacts the hot air to evaporate 1 / 3 of the moisture. The preheating lifting plate further propels the material forward into the front tube bundle dryer (i.e., the heating tube bundle). Steam enters the heating tube bundle 4 through the rotary joint 1 of the steam inlet and water outlet channels. After condensation, it flows from the condensate outlet pipe 1-3 to the condensate outlet 1-1 for discharge. After being heated, the heating tube bundle 4 exchanges heat with the material from the preheating section. The material is lifted by the heating lifting plate 5 in the heating tube bundle 4 section and fully contacts the heating tube bundle 4 for heat exchange, drying to the required moisture content. The heating lifting plate 5 pushes the material to the fixed discharge end 2 for discharge.

[0023] The evaporated dry and wet gas is discharged through the condensate outlet 1-1 via the condensate liquid, and the gas is discharged to the exhaust gas treatment device through the exhaust port at the top of the fixed discharge end 2.

[0024] This invention addresses the limitation of traditional tube bundle dryers in handling high-viscosity, high-moisture materials. It proposes a method that uses high-temperature preheating at the front end to evaporate one-third of the moisture, reducing viscosity and moisture content before the material enters the tube bundle dryer. However, two separate sets of equipment require two separate drive units, resulting in high investment and operating costs. Therefore, this invention combines high-temperature preheating with the tube bundle dryer into an integrated device, reducing costs and optimizing the production process.
