Description

Technical Field

[0001] The present invention application relates to the technical field of drying devices, and specifically to a non-contact multi-burner heating carbon black drying device and its usage method. Background Art

[0002] In the production process of wet granulation of carbon black by the oil furnace method, the drying link is a very crucial one, because the drying effect directly affects the product quality and production efficiency of carbon black. For traditional drying technologies, such as hot air drying and steam drying, the main principle of hot air drying is to transfer heat through the contact between hot air and wet carbon black to achieve the evaporation of moisture and the drying of carbon black. Although this drying method is mature, there are a series of problems. Traditional carbon black drying devices usually consist of parts such as hot air pipelines, drying cylinders, fans, moisture exhaust systems, and control systems. The hot air comes from carbon black tail gas, the drying cylinder is used to accommodate wet carbon black, the hot air transfers heat to the carbon black through the baffles inside the cylinder, and at the same time, the moisture is discharged through the moisture exhaust system. The control system is used to adjust parameters such as hot air temperature, air volume, and drying time. Although it has been widely used, there are problems such as high energy consumption, uneven drying, and environmental pollution, and it urgently needs to be improved.

[0003] The main problems of traditional carbon black drying devices include: there is uneven drying in traditional drying devices; due to the differences in particle size and density of carbon black, the distribution of hot air in the drying cylinder is uneven, resulting in insufficient drying of some carbon black; the contact time between carbon black and hot air is long, and thermal aging is likely to occur, reducing the specific surface area and structural properties of carbon black; the thermal efficiency of the drying device is relatively low, usually only about 50%, and a large amount of heat is discharged into the environment through the moisture exhaust system, causing energy waste. At the same time, the flue gas and noise pollution generated by burning fuel are serious, which does not meet the modern environmental protection requirements. The control system of traditional drying devices is relatively simple, and it is difficult to accurately adjust drying parameters, affecting the drying effect and production efficiency. The drying capacity of traditional drying devices is limited, and it is difficult to meet the needs of large-scale production. The equipment is large and heavy, and the installation and maintenance are difficult, increasing the production cost. Summary of the Invention

[0011] Further, a rotating cylinder is rotatably connected to the side of the heating air blower away from the drying sleeve through a bearing. A connecting frame is fixed inside the rotating cylinder. The side end of the connecting frame is fixedly connected to the fan rotating shaft.

[0012] Further, each heating tube is arranged in a spiral shape. The heating tube away from the fan end extends into the rotating tube. A filter screen plate is fixedly installed on the side of the rotating cylinder away from the heating air blower through bolts.

[0013] Further, the heat recovery component includes a heat recovery tube, a water inlet and a water outlet. A heat recovery tube is fixedly sleeved on the outer surface of the exhaust pipe.

The water outlet is fixedly penetrated and installed on the heat recovery tube near the drying sleeve end.

[0014] Further, a usage method of a non-contact multi-burner heating carbon black drying device, the usage method includes the following steps: Step A, carbon black drying; Step A1, connect the feed pipe orifice with the wet carbon black discharge orifice through a pipeline, fix the feed pipe orifice and the pipeline through bolts, and then fix the discharge pipeline and the discharge pipe orifice through a flange; Step A2, discharge the wet carbon black into the drying sleeve through the feed pipe orifice. At this time, the servo motor operates to drive the connection rotating shaft to rotate. When the connection rotating shaft rotates, it drives the second gear to rotate. The second gear drives the first gear meshed with it to rotate, thereby driving the rotating tube to rotate. When the rotating tube rotates, it drives the drying drum to rotate. When the drying drum rotates, it drives the guiding spiral plate to rotate. When the guiding spiral plate rotates, it drives the wet carbon black to move inside the drying sleeve; Step A3, turn on the microwave sleeve.

The pulley drives the pulley on the rotating cylinder through the high-temperature resistant belt, thereby driving the rotating cylinder to rotate. When the rotating cylinder rotates, it drives the connecting frame to rotate. The connecting frame drives the fan to rotate. When the fan rotates, it inhales the external air flow and discharges it into the heating air blower; Step B2: When the microwave sleeve is operating, the heating tubes are turned on synchronously. Before the air flow enters the heating air cylinder, it is filtered through the filter screen plate. After the air flow enters the interior of the heating air cylinder and passes through the heating tubes, the heating tubes heat and dry the air flow. The high-temperature air flow after drying enters the interior of the drying drum. Step B3: After the high-temperature air flow enters the interior of the drying drum, under the air-permeable characteristics of the drying drum, the moisture in the carbon black distributed on the outer surface of the drying drum and the steam after the carbon black is heated by the microwave are discharged into the interior of the exhaust pipe, and the carbon black is further heated. Step C: Preheating and recovery of high-temperature hot air Step C1: Fix the water pipe connected to the water pump through the flange on the water inlet, connect the water inlet end of the water pump to the cold water tank, and then fix the water pipe connected to the hot water tank through the flange on the water outlet, and install a one-way valve on the water pipe. Step C2: When the microwave sleeve is operating, the water pump operates synchronously to pump cold water into the interior of the heat recovery pipe, so that the interior of the heat recovery pipe is filled with cold water. After the high-temperature hot air enters the interior of the exhaust pipe, it exchanges heat with the cold water in the interior of the heat recovery pipe. Open the one-way valve, and the hot water after heat exchange is discharged into the hot water tank. Step D: Equipment maintenance Step D1: After each drying is completed, the equipment is shut down. Turn the nut to release the fixation between the filter screen plate and the rotating cylinder, remove the filter screen plate for cleaning. After cleaning and drying, fix it on the rotating cylinder through the nut and bolt. Step D2: When cleaning the drying drum, turn the nuts on the fixed sleeve plate at the exhaust pipe end and the connection between the rotating pipe and the connecting ring plate to release the fixation between the fixed sleeve plate and the drying sleeve and between the rotating pipe and the connecting ring plate. Pull the exhaust pipe to pull out the drying drum and the guiding spiral plate from the interior of the drying sleeve, and then the drying drum can be cleaned. After cleaning, insert the drying drum and the guiding spiral plate into the interior of the drying sleeve, align and engage the rotating pipe with gear two, and then fix the fixed sleeve plate to the drying sleeve and the rotating pipe to the connecting ring plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the present invention, microwaves are generated by the magnetrons annularly arranged outside the drying sleeve. Utilizing the characteristics of high-frequency electromagnetic waves of microwaves, heat is generated through the molecular vibration and interaction inside the material, realizing the drying of carbon black. The carbon black is heated to a high temperature in a short time, so that the moisture inside the carbon black evaporates rapidly, thereby improving the drying efficiency, solving the problems of uneven heating, easy thermal aging and poor environmental protection performance of the existing carbon black drying devices during use, avoiding direct contact between the material and the heat source, reducing the energy loss in the heat transfer process, and thus avoiding the thermal aging and pollution of the material.

[0016] 2. In the present invention, through the rotatable drying drum and the guiding spiral plate, during drying, carbon black can be evenly distributed inside the drying sleeve, further ensuring the uniformity of drying. When the guiding spiral plate rotates, it drives the carbon black from the feed pipe orifice to the discharge pipe orifice, thus facilitating the normal feeding and discharging of carbon black and improving the practicality of the drying device.

[0017] 3. While performing microwave drying, another non-contact heat source, i.e., hot air at the feed end, is used to heat the carbon black. At the same time, the air flow inside the drying drum is increased. In combination with the breathable design of the drying drum, the moisture inside the carbon black can be quickly removed. The non-contact drying technology avoids the direct contact between the carbon black and the heating element in traditional contact drying, thereby reducing the pollution and heat loss of the carbon black and improving the drying effect. Meanwhile, the filter plate at the air inlet end prevents foreign matters from being carried in when the air flow enters.

[0018] 4. When the high-temperature hot gas discharged after drying passes through the heat recovery pipe, the wrapped flowing water inside the heat recovery pipe can recover the heat in the high-temperature hot gas, improving the environmental performance of the drying device. Moreover, the heating can remove the moisture in the air flow to be introduced into the drying drum, further improving the drying effect of the drying device. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Working principle: When drying carbon black, the feeding pipe orifice 6 is connected to the wet carbon black discharge orifice through a pipeline, and the feeding pipe orifice 6 is fixed to the pipeline by bolts. Then, the discharging pipeline is fixed to the discharging pipe orifice 7 through a flange. The wet carbon black is discharged into the drying sleeve 1 through the feeding pipe orifice 6. At this time, the servo motor 31 operates to drive the connecting rotating shaft 15 to rotate. When the connecting rotating shaft 15 rotates, it drives the second gear 14 to rotate. The second gear 14 drives the first gear 13 meshed with it to rotate, thereby driving the rotating pipe 30 to rotate. When the rotating pipe 30 rotates, it drives the drying drum 4 to rotate. The rotation of the drying drum 4 drives the guiding spiral plate 5 to rotate. When the guiding spiral plate 5 rotates, it drives the wet carbon black to move towards the inside of the drying sleeve 1. The magnetron inside the microwave sleeve 2 generates microwaves.

The air flow is filtered through the filter screen plate 23 before entering the heating air cylinder 17. After the air flow enters the heating air cylinder 17, when passing through the heating pipe 19, the heating pipe 19 heats and dries the air flow. The dried high-temperature air flow enters the drying drum 4. After the high-temperature air flow enters the drying drum 4, under the air permeability of the drying drum 4, the moisture in the carbon black distributed on the outer surface of the drying drum 4 and the steam after the carbon black is heated by microwaves are discharged into the exhaust pipe 12, and the carbon black is further heated; High-temperature hot air preheating and recovery: The water pipe connected to the water pump is penetrated and fixed on the water inlet orifice 27 through a flange. The water inlet end of the water pump is connected to the cold water tank. Then, the water pipe connected to the hot water tank is penetrated and fixed on the water outlet orifice 28 through a flange, and a one-way valve is installed on the water pipe. When the microwave sleeve 2 operates, the water pump operates synchronously to pump cold water into the heat recovery pipe 26, so that the heat recovery pipe 26 is filled with cold water. After the high-temperature hot air enters the exhaust pipe 12, it exchanges heat with the cold water inside the heat recovery pipe 26. The one-way valve is opened, and the hot water after heat exchange is discharged into the hot water tank; Equipment maintenance: After each drying is completed, turn off the equipment and turn the nut to release the fixation between the filter screen plate 23 and the rotating cylinder 21. Remove the filter screen plate 23 for cleaning. After cleaning and drying, fix it on the rotating cylinder 21 through the nut and bolt.

Pull the exhaust pipe 12 to pull out the drying cylinder 4 and the guiding spiral plate 5 from the inside of the drying sleeve 1, and then the drying cylinder 4 can be cleaned. After cleaning, insert the drying cylinder 4 and the guiding spiral plate 5 into the inside of the drying sleeve 1 to align and engage the rotating pipe 30 with the second gear 14, and then fix the fixing sleeve plate 9 and the drying sleeve 1 and fix the rotating pipe 30 and the connecting ring plate 16.

Under the action of the high-frequency electromagnetic waves of the microwaves, the molecules inside the material vibrate and interact with each other to generate heat, heating the carbon black to a high temperature in a short time to achieve carbon black drying. Step (B), synchronous hot air drying; Step (B), when the servo motor operates to drive the connecting rotating shaft to rotate, it synchronously drives the pulley sleeve to rotate. The pulley sleeve drives the pulley sleeve on the rotating cylinder through a high-temperature resistant belt, thereby driving the rotating cylinder to rotate. When the rotating cylinder rotates, it drives the connecting frame to rotate. The connecting frame drives the fan to rotate. When the fan rotates, it inhales external air flow and discharges it into the heating hair dryer. Step (B), when the microwave sleeve operates, turn on the heating tube synchronously. The air flow is filtered through the filter screen plate before entering the heating hair dryer. After the air flow enters the heating hair dryer, when passing through the heating tube, the heating tube heats and dries the air flow. The dried high-temperature air flow enters the drying drum. Step (B), after the high-temperature air flow enters the drying drum, under the breathable characteristics of the drying drum, the moisture in the carbon black distributed on the outer surface of the drying drum and the steam after the carbon black is heated by microwaves are discharged into the exhaust pipe, and the carbon black is further heated. Step (C), high-temperature hot air preheating recovery; Step (C), fix a water pipe connected to a water pump through a flange on the water inlet pipe opening. The water inlet end of the water pump is connected to a cold water tank. Then fix a water pipe connected to a hot water tank through a flange on the water outlet pipe opening, and a one-way valve is installed on the water pipe. Step (C), when the microwave sleeve operates, the water pump operates synchronously to pump cold water into the heat recovery tube, so that the heat recovery tube is filled with cold water. After the high-temperature hot air enters the exhaust pipe, it exchanges heat with the cold water in the heat recovery tube. Open the one-way valve, and the hot water after heat exchange is discharged into the hot water tank. Step (D), equipment maintenance; Step (D): After each drying is completed, the equipment is shut down, and the nut is turned to release the fixation between the filter screen plate and the rotating cylinder. Then the filter screen plate is removed for cleaning. After cleaning and drying, it is fixed to the rotating cylinder through the nut and bolt again. Step (D): When cleaning the drying cylinder, turn the nuts on the fixed sleeve plate at the exhaust pipe end and at the connection between the rotating pipe and the connecting ring plate to release the connection between the fixed sleeve plate and the drying sleeve as well as between the rotating pipe and the connecting ring plate. Pull the exhaust pipe to pull out the drying cylinder and the guiding spiral plate from inside the drying sleeve, and then the drying cylinder can be cleaned. After cleaning, insert the drying cylinder and the guiding spiral plate into the inside of the drying sleeve to align and engage the rotating pipe with Gear II, and then fix the fixed sleeve plate to the drying sleeve and the rotating pipe to the connecting ring plate.
