Description

TECHNICAL FIELD

[0001] The application relates to the technical field of chemical dye drying processing, in particular to a drying cylinder structure for chemical dye processing. BACKGROUND

[0002] A double-cone rotary vacuum dryer is a double-cone drying cylinder structure, and is one of the most commonly used drying equipment for chemical dyes. The double-cone rotary vacuum dryer is used to remove water in the chemical dyes through heating and evaporation, so as to obtain dried chemical dyes. The double-cone rotary vacuum dryer usually adopts an indirect heating method, that is, the heat of external hot gas is transferred to the chemical dyes through indirect heat conduction, so that the water in the chemical dyes is evaporated into water vapor, and the water vapor in the double-cone drying cylinder is pumped out through a vacuum pump, so that the desired drying effect is achieved.

[0003] The specific steps of the current chemical dye drying process are as follows: first, wet chemical dyes are put into the drying cylinder, then hot gas is introduced to transfer heat to the drying cylinder through heat conduction, and at the same time, the drying cylinder continuously rotates, and the water vapor in the drying cylinder is pumped out through the trap located in the drying cylinder, so that continuous drying is carried out.

[0004] For the current drying process, the following problems exist: part of the chemical dyes is agglomerated after drying, which is easy to adhere to the wall of the drying cylinder and the shell of the trap, so that it is difficult for heat to be transferred to the remaining chemical dyes in the drying cylinder, which affects the heat transfer effect, the heating and drying effect of the chemical dyes is not good, and the overall work efficiency is affected. Secondly, the chemical dyes adhered to the shell of the trap are easy to block the through holes of the trap for trapping water vapor, so that the process of pumping out water vapor (i.e. the final drying process) is affected, and in severe cases, the dryer is difficult to normally carry out drying work. In addition, the current method of improving the probability of contact between the chemical dyes and the wall of the drying cylinder is only through the rotation of the drying cylinder, but due to the limited area of the wall of the drying cylinder and the large amount of chemical dyes that need to be dried, the heating effect of part of the chemical dyes is not good, and the overall drying efficiency is not ideal.

DETAILED DESCRIPTION

[0034] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of ways beyond the specific embodiments described and illustrated herein, and it is therefore intended that the present application not be limited to the embodiments.

[0035] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, a drying cylinder structure for chemical dye processing includes two left and right distributed racks, and a double-cone cylinder 1 is arranged on the two racks to rotate together. The upper and lower sides of the double-cone cylinder 1 are respectively provided with a feed port and a discharge port. A heating system 10 is arranged on the right side of the double-cone cylinder 1. The heating system 10 includes an air inlet pipe 11 and an air outlet pipe 12 arranged on the right rack. The air inlet pipe 11 and the air outlet pipe 12 are connected to the heating chamber 210 on the double-cone cylinder 1 through their respective corresponding rotary spray diverters (for existing technology) and corresponding connecting pipes. The left side of the double-cone cylinder 1 is provided with a drying system The drying system 13 includes a connecting pipe 14, and a connecting pipe 14 with an axis extending from left to right is provided on the left side frame. One end of the connecting pipe 14 is located in the double-cone cylinder 1 and is fixedly provided with a collector 15 for collecting water vapor. The connecting pipe 14 is connected to an external vacuum pump. It should be noted that the collector 15 is a prior art, and a filter element for filtering materials is provided on it, such as a filter mesh that can filter chemical dyes. A cleaning mechanism 2 for cleaning the double-cone cylinder 1 and improving the drying effect of chemical dyes is provided in the double-cone cylinder 1.

[0036] like Figure 3 and Figure 4 As shown, the cleaning mechanism 2 includes a scraping unit 20, and a scraping unit 20 for cleaning the cylinder wall by rotating scraping is provided in the double-cone cylinder 1. The scraping unit 20 includes a scraping plate 200. Two scraping plates 200 distributed up and down are provided in the double-cone cylinder 1. The scraping plates 200 are divided into a horizontal section, an inclined section and a vertical section. The inclined section is used to fit with the conical surface of the double-cone cylinder 1, and the vertical section is used to fit with the cylinder wall of the vertical section of the double-cone cylinder 1. The two scraping plates 200 jointly clean the inner wall of the double-cone cylinder 1. The scraping unit 20 also includes a cleaning plate 201 for cleaning the collector 15 in the drying system 13.

[0037] like Figure 3 and Figure 7 As shown, an auxiliary heating chamber 216 is provided in the scraper plate 200, and a heat conducting part 21 is provided in the double cone 1. Part of the hot air in the heating system 10 is intermittently conducted to the scraper plate 200 through the heat conducting part 21, forming a heating and drying process with internal and external heating.

[0038] like Figure 3 As shown, a driving unit 23 is provided in the double-cone cylinder 1, and the driving unit 23 enables the scraping plate 200 and the cleaning plate 201 to perform cleaning or scraping operations by synchronously rotating when the double-cone cylinder 1 rotates.

[0039] It should be noted that the driving system adopts the existing technology currently applied in the double-cone rotary vacuum dryer, and the driving system operates to make the double-cone drum 1 rotate in a whole circle. When working, the staff first puts the chemical dyes to be dried into the double-cone drum 1 through the feeding port, then seals and blocks the feeding port, and the driving system, the heating system 10 and the drying system 13 operate simultaneously, the double-cone drum 1 rotates in a whole circle, and in the rotating process, the hot air generated by the heating system 10 is pumped into the double-cone drum 1 (the chamber where the chemical dyes are not placed), so as to indirectly heat the chemical dyes, and the water vapor generated by drying in the chemical dyes is captured and extracted by the trap 15 in the drying system 13, so as to perform the drying operation on the chemical dyes.

[0040] In the above process, the double-cone drum 1 rotates in a whole circle by the existing driving mode, driving the chemical dyes to roll and turn synchronously, and then the driving part 23 is driven by the rotation of the double-cone drum 1, and the scraping plate 200 and the cleaning plate 201 are driven synchronously by the driving part 23. The scraping plate 200 cleans the inner wall of the double-cone drum 1 to avoid the problem that the chemical dyes adhere to the inner wall of the double-cone drum 1, affecting the heat transfer and indirectly affecting the overall drying effect. The cleaning plate 201 cleans the trap 15 to avoid the problem that the chemical dyes adhere to the surface of the trap 15, and the problem that the drying operation cannot be performed due to the failure of the water vapor to be extracted out of the double-cone drum 1, and part of the hot air is intermittently introduced into the scraping plate 200 by the heat conduction part 21. The scraping plate 200 and the double-cone drum 1 form double heating and drying inside and outside, and the drying effect of the chemical dyes is improved.

[0041] As shown in Figure 3 and Figure 4 , the scraping unit 20 further comprises a fixed frame 202, two fixed frames 202 are fixedly arranged in the double-cone drum 1 in an up-down distribution, and the two fixed frames 202 are arranged at the feeding port and the discharging port respectively. An annular frame 203 is fixedly arranged on the drying system 13 in a circumferential distribution, and an annular groove is formed in the annular frame 203. Two sliding blocks 204 are slidably arranged in the annular groove in an up-down distribution. An L-shaped support 26 is fixedly arranged on the right side end of the sliding block 204. The cleaning plate 201 is fixedly arranged on the support 26, and the cleaning plate 201 is arc-shaped. A brush (usually an industrial brush resistant to chemicals) for cleaning the trap 15 is arranged on the inner arc surface of the cleaning plate 201. A rotating shaft 205 is rotatably arranged between the sliding block 204 and the corresponding fixed frame 202. The horizontal section of the scraping plate 200 is fixedly sleeved on the corresponding rotating shaft 205.

[0042] As shown in Figure 3 and Figure 4 , the driving part 23 comprises a bevel gear ring 230, and the bevel gear ring 230 is fixedly sleeved on the annular frame 203. A bevel gear 231 engaged with the bevel gear ring 230 is fixedly sleeved on the rotating shaft 205.

[0043] In the process of driving the double-cone cylinder 1 to rotate, the double-cone cylinder 1 drives the two rotating shafts 205 and the bevel gear 231 to rotate synchronously, so that the bevel gear 231 revolves around the axis of the connecting pipe 14 (i.e., rotates up and down), and at the same time, through the meshing between the bevel gear 231 and the bevel gear ring 230, the bevel gear 231 and the corresponding rotating shaft 205 rotate (i.e., rotate horizontally), so that the rotating shaft 205 can also drive the scraping plate 200 to rotate synchronously around the axis of the double-cone cylinder 1 in the process of rotating the double-cone cylinder 1, so that the scraping plate 200 scrapes the inner wall of the double-cone cylinder 1, avoiding the influence of the attached chemical dyes on the overall drying effect, and secondly, the sliding block 204 drives the cleaning plate 201 to rotate synchronously through the support 26, and the cleaning plate 201 drives the brush on it to clean the outer side wall of the trap 15, avoiding the influence of the blockage of the trap 15 on the process of trapping water vapor in the double-cone cylinder 1. In summary, the drying effect of the chemical dyes is improved.

[0044] As shown in Figure 4 and Figure 7 , the rotating shaft 205 and the corresponding scraping plate 200 are jointly fixed with the support 24, and the support 24 and the corresponding scraping plate 200 are jointly fixed with the reinforcing member 240 for strengthening the overall strength of the scraping plate 200, the rotating shaft 205 and the support 24. In order to improve the drying speed of the chemical dyes and the overall drying quality in the process of rotary drying, the support 24 is provided with a stirring part 25 for assisting the drying of the chemical dyes, which includes a stirring plate 250. Through the rotation of the stirring plate 250, the chemical dyes are agitated, so that the contact area (contact probability) of the chemical dyes with the double-cone cylinder 1 is increased, thereby improving the drying effect. The front and rear sides of the support 24 are fixedly provided with prismatic stirring plates 250, and the upper and lower sides of the stirring plates 250 are fixedly provided with a plurality of crushing tips 251 arranged equidistantly from front to rear.

[0045] In the process of rotary drying, the reinforcing member 240 is arranged to strengthen the connection strength between the scraping plate 200, the rotating shaft 205 and the support 24, so as to avoid the influence of the reduction of the fitting degree between the scraping plate 200 and the inner wall of the double-cone cylinder 1 and the fitting degree between the cleaning plate 201 and the trap 15 due to long-time rotary drying operation on the cleaning effect.

[0046] The prismatic part of the stirring plate 250 and the crushing tip 251 will crush the chemical dyes in block shape after drying in the process of rotation, and make part of the chemical dyes dry again, so as to ensure that the internal moisture is fully vaporized, thereby improving the overall drying effect.

[0047] As shown in Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, the heat-conducting part 21 comprises a heating cavity 210, two upper and lower symmetrical heating cavities 210 are arranged in the double-cone cylinder 1, the air inlet pipe 11 and the air outlet pipe 12 in the heating system 10 are communicated with the two heating cavities 210 respectively, and the upper heating cavity 210 is taken as an example for description, the heating cavity 210 comprises a small communication cavity 211, a circumferential group and a large communication cavity 213 arranged in sequence from top to bottom, the small communication cavity 211 and the large communication cavity 213 each comprise two left and right distributed fan-shaped cavities, the circumferential group comprises a plurality of circumferentially distributed heating sub-cavities 212, the fan-shaped cavities are communicated with the corresponding adjacent heating sub-cavities 212, the upper fixed frame 202 is provided with a flow-through cavity 214 for communicating the left and right small communication cavities 211, a through cavity 215 is arranged between the left two large communication cavities 213, the hot air enters the corresponding plurality of heating sub-cavities 212 from the right large communication cavity 213 through the air inlet pipe 11, and then gradually enters the right small communication cavity 211, and then sequentially enters the left small communication cavity 214, the left corresponding fan-shaped cavity and the large communication cavity 213 through the flow-through cavity 214, and then enters the lower heating cavity 210 through the through cavity 215, and then repeats the above process in the lower heating cavity 210, and finally flows out of the double-cone cylinder 1 through the air outlet pipe 12.

[0048] In work, the external air pump pumps the hot air into the right upper large communication cavity 213 through the air inlet pipe 11, the hot air gradually enters the heating sub-cavities 212, and then enters the flow-through cavity 214 through the right upper small communication cavity 211, and then the hot air enters the left heating sub-cavities 212 through the left upper small communication cavity 211, and then flows into the left lower heating cavity 210 through the through cavity 215, and then repeats the above process, and finally flows into the air outlet pipe 12 for discharge. In summary, the hot air uniformly passes through the double-cone cylinder 1, which improves the heat transfer efficiency and thus improves the overall drying effect.

[0049] As shown in Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , the heat-conducting part 21 further comprises a shunt cavity 217, two left and right distributed shunt cavities 217 are arranged on the support frame 24, the shunt cavity 217 close to the scraping plate 200 is communicated with the auxiliary heating cavity 216, two upper and lower distributed flow guide cavities 218 are arranged on the rotating shaft 205, the flow guide cavity 218 close to the fixed frame 202 is communicated with the auxiliary heating cavity 216 and the flow-through cavity 214, the other flow guide cavity 218 is communicated with the adjacent shunt cavity 217 and the left heating cavity 210, and two left and right distributed built-in cavities 219 are arranged in the stirring plate 250, the two built-in cavities 219 are communicated with each other, and the two built-in cavities 219 are respectively communicated with the two shunt cavities 217.

[0050] As shown in Figure 6 , Figure 7 andFigure 8 As shown, the horizontal section of the scraping plate 200 is fixedly provided with two front and rear symmetrical fan-shaped rings 220 which are in close contact with the fixed frame 202. The horizontal section of the scraping plate 200 and the fan-shaped rings 220 are provided with a guide-out groove 221. The guide-out groove 221 is communicated with the flow guide cavity 218 on the rotating shaft 205 through a butt joint pipe. The fixed frame 202 is provided with a guide-out pipe 222 which is butt jointed with the guide-out groove 221. The other end of the guide-out pipe 222 extends into the heating auxiliary cavity 212 in the adjacent side heating cavity 210. The position of the guide-out pipe 222 is close to the position where the hot gas flows out of the fixed frame 202.

[0051] In the process that the hot gas passes through the upper side flow-through cavity 214, the rotating shaft 205 drives the scraping plate 200 and the fan-shaped ring 220 to rotate around the whole circle. When the fan-shaped ring 220 rotates to the position where the guide-out groove 221 on the fan-shaped ring 220 is opposite to the guide-out pipe 222, the guide-out pipe 222, the guide-out groove 221, the butt joint pipe, the auxiliary heating cavity 216, the flow distribution cavity 217, the flow guide cavity 218, the heating cavity 210 and the built-in cavity 219 are communicated. Thus, part of the hot gas enters the auxiliary heating cavity 216 on the scraping plate 200 through the flow guide cavity 218, and then enters the built-in cavity 219 on the right side through the flow distribution cavity 217. In the above process, the scraping plate 200 and the stirring plate 250 can both transfer heat. Then, the hot gas flows to the other flow guide cavity 218 on the rotating shaft 205 through the built-in cavity 219 and the corresponding flow distribution cavity 217, and enters the guide-out pipe 222 through the flow guide cavity 218 and the butt joint pipe. Finally, the hot gas returns to the left side heating auxiliary cavity 212. It is to be noted that when the guide-out groove 221 is misaligned with the guide-out pipe 222, the above flow-through circuit stops connecting the hot gas flow loop, but the scraping plate 200 and the stirring plate 250 still have the transfer effect. With the continuous rotation of the rotating shaft 205, the above loop intermittently connects the hot gas flow line, and the hot gas in the scraping plate 200 and the stirring plate 250 is intermittently replaced, so as to ensure the heat transfer. At the same time, the intermittent replacement does not affect the original hot gas flow line and the heat transfer efficiency of the left side double cone cylinder 1.

[0052] In summary, the indirect auxiliary heating mode realizes the internal and external double heat transfer effect. The scraping plate 200 and the stirring plate 250 continuously rotate around the whole circle, so as to improve the overall heat transfer effect, and finally improve the drying effect of the chemical dye.
