Detailed Implementation

[0034] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and not to limit the present application.

[0035] Due to the characteristics of fine dust and strong viscosity of the glass kiln flue gas, when the flue gas flows from the inside of the ventilation pipeline, more impurities will adhere to the inner wall of the pipeline, which not only increases the difficulty of flue gas treatment, but also causes corrosion to the inner wall of the ventilation pipeline, affecting the safety of the ventilation pipeline.

[0036] In order to solve the above problems, the following scheme is proposed.

[0037] Example one

[0038] Please refer to Figure 1 , Figure 2 and Figure 3 , a flue gas treatment system of a glass kiln is proposed, which comprises a desulfurizer storage bin 20, a desulfurizing tower 30, a settling chamber 40, a dust collector 50 and an air induction assembly 60.

[0039] Specifically, the desulfurizing tower 30 and the settling chamber 40, the settling chamber 40 and the dust collector 50, and the dust collector 50 and the air induction assembly 60 are communicated by setting the ventilation pipe 10, the ventilation pipe 10 comprises the straight pipe 11 and the turning pipe 12 connected with the straight pipe 11 for adjusting the direction of the pipeline, the pipe wall of the straight pipe 11 is composed of a plurality of rotatable turning plates 113, and the turning plate 113 is rotated to drive the side surface adhering impurities to rotate to the outside of the straight pipe 11.

[0040] The desulfurizer storage bin 20, the desulfurizing tower 30, the settling chamber 40, the dust collector 50 and the air induction assembly 60 form a complete flue gas treatment system, which assists the ventilation pipe 10 to communicate and transport airflow. In order to ensure the cleaning of the inner wall of the ventilation pipe 10, the inner wall of the straight pipe 11 is set as the turning plate 113, and the turning plate 113 is combined to form a ring-shaped pipe body structure. In this case, the end face of the pipe body structure can be switched by rotating the turning plate 113. When the end face of the turning plate 113 adheres to more attachments after long-term use, the inner side wall can be rotated to the outside by rotating the turning plate 113. At this time, the clean outer side of the inner side wall is rotated to the inside, and the turning plate 113 rotated to the inside also forms the inner wall of the pipe body structure, which still ensures the forming state of the pipeline.

[0041] Since the straight pipe 11 can be long, and only the protruding shaft body at both ends of the turning plate 113 is set to rotate, the shaft body may be broken. In order to avoid this problem, please refer to Figure 3 and Figure 10The straight pipe 11 comprises at least two positioning rings 112, which are arranged on both sides of a rotating plate 113, and a plurality of connecting plates 111 are fixed at equal intervals in a ring shape between the two positioning rings 112. One end of the rotating plate 113 is provided with a positioning groove 1132, which is arranged at the middle position of the lower side of the connecting plate 111. The inside of the positioning groove 1132 is detachably fixed with a rotating shaft 114, and both ends of the rotating shaft 114 are rotatably arranged in the inside of the positioning ring 112.

[0042] The two ends of the straight pipe 11 are fixed and positioned by the positioning rings 112. The structure between the two positioning rings 112 is a pipe body, and the positioning between the two positioning rings 112 is achieved by the connecting plate 111, that is, the straight pipe 11 is in a straight state. In this case, only the connecting plate 111 is needed to connect the two positioning rings 112 to form a circular pipe-shaped frame in a straight state. On the basis of the frame, the rotating plate 113 is installed.

[0043] The installation mode is to rotatably connect the two ends of the penetrating rotating shaft 114 with the positioning ring 112. This connection mode is a support formed by the rotating shaft 114 as a whole, which can reduce the extrusion force per unit area and ensure the stable connection and rotation between the rotating shaft 114 and the rotating plate 113.

[0044] The installed rotating plate 113 is driven by the rotating shaft 114. As long as the rotating shaft 114 is arranged at the middle position of the connecting plate 111, it can be ensured that when the rotating shaft 114 rotates, the connecting plate 111 rotates to the same amplitude on both sides and can be in contact with the connecting plate 111, forming a pipe-like structure. The inner wall of the straight pipe 11 of this structure is not a circular notch, but has a certain protruding angle. This protruding angle does not affect the flow of gas, so it does not affect the overall structure.

[0045] In an embodiment, please refer to Figure 11 The inside of the positioning ring 112 is provided with an inner cavity 1121, and the inside of the inner cavity 1121 is provided with a driving assembly for driving the rotating shaft 114 to rotate.

[0046] The inner cavity 1121 is arranged in the inside of the positioning ring 112, and the driving assembly for driving the rotating shaft 114 to rotate is arranged in the inside of the inner cavity 1121. This arrangement is to reduce the exposure of the structure to the outside and avoid damage to the exposed structure during daily use.

[0047] Specifically, please refer to Figure 8 、 Figure 9 and Figure 11The driving assembly comprises a secondary shaft 1122 rotatably arranged inside the inner cavity 1121, a gear ring 1123 engaged with the outer side of the secondary shaft 1122, a plurality of rotating shafts 114 engaged with the gear ring 1123, a synchronous belt 1151 wound around the outer side of the secondary shaft 1122, and a motor 122 connected to the other end of the synchronous belt 1151.

[0048] That is, the motor 122 drives the synchronous belt 1151 to rotate, the rotation of the synchronous belt 1151 drives the secondary shaft 1122 to rotate, the rotation of the secondary shaft 1122 drives the gear ring 1123 to rotate, and the rotation of the gear ring 1123 drives the plurality of rotating shafts 114 to rotate. All the above-mentioned linkages are synchronous and in the same direction, which means that the plurality of rotating shafts 114 rotate in the same direction, thereby realizing the synchronization of the adjustment of the rotating plate 113 and ensuring that the adjustment of the rotating plate 113 can be synchronized.

[0049] Since the straight pipes 11 may be more, if the cavity area inside the positioning ring 112 is too large, the strength of the positioning ring 112 may be reduced, that is, the positioning ring 112 may be twisted during daily use. In order to reduce the cavity area inside the inner cavity 1121, the motor 122 is arranged outside, Figure 9 and Figure 11 The other end of the synchronous belt 1151 is wound around a linkage shaft 115, the linkage shaft 115 is used to connect the synchronous belts 1151 inside the two positioning rings 112, the outer side of the linkage shaft 115 is wound around a synchronous belt 1152, and the power end of the motor 122 is connected to the synchronous belt 1152.

[0050] That is, an additional set of synchronous belt 1152 is arranged to assist in connecting the linkage shaft 115, the shaft body used for driving is arranged outside the positioning ring 112, and then the power end of the motor 122 is connected to the synchronous belt 1152, thereby forming the entire driving assembly and ensuring the synchronous rotation of the rotating plate 113.

[0051] Since the connection between the rotating plate 113 and the connecting plate 111 is formed by rotation, after the motor 122 stops rotating, a gap may exist between the rotating plate 113 and the connecting plate 111 due to the slight deformation of the material of the rotating plate 113. In order to reduce this gap, please refer to Figure 10 The outer side of the connecting plate 111 is detachably provided with a sealing plate 116, the two side lower end faces of the sealing plate 116 are coated with sealing glue, and the rotating plate 113 is rotated to fit the position coated with sealing glue of the sealing plate 116.

[0052] The sealing is formed by coating the inside of the sealing plate 116 with sealing glue, which is a non-cured glue that only strengthens the connection between structures by adhesion, and this connection is because the internal air pressure of the straight pipe 11 is low when the flue gas is discharged, and this sealing by sealing glue can still ensure the sealing of the structure when the internal air pressure of the straight pipe 11 is low.

[0053] In addition, since the pipe wall of the straight pipe 11 is formed by the rotation of the rotating plate 113, and the rotation range of the rotating plate 113 is controllable, after a period of use, if the sealing glue cannot completely seal, or there are some attachments that cannot be directly cleaned between the connecting plate 111 and the rotating shaft 114, the rotating plate 113 can be rotated to the position facing the center of the straight pipe 11, so that the cleaning device can directly probe into the interior of the straight pipe 11 for cleaning, which is convenient to operate and can clean the attachments in the more hidden position inside when comprehensive cleaning is needed.

[0054] The sealing plate 116 can be fixed by bolts, as shown in Figure 7 , a threaded hole is provided on the surface of the positioning ring 112 to connect the inside of the sealing plate 116, and the bolt is inserted into the inside of the sealing plate 116 from the threaded hole on the surface of the positioning ring 112 to form a fixed connection. This fixed connection can be disassembled by simply unscrewing the bolt, and this method can avoid the blocking of the threaded hole by the connecting flange of the rotating pipe 12 when disassembling the sealing plate 116 due to structural problems, and the outer ring of the connecting flange of the rotating pipe 12 is lower than the threaded hole.

[0055] In addition, the threaded hole can also be provided in a way that penetrates into the inside of the connecting plate 111, that is, the bolt can directly penetrate from the end surface of the sealing plate 116 to the connecting plate 111 to form a fixed connection. This fixed connection requires more bolts, but does not need to disassemble the connection between the positioning ring 112 and the rotating pipe 12, that is, it does not need to consider the connection area between the rotating pipe 12 and the positioning ring 112, and has a wider range of application.

[0056] When the rotating plate 113 is in a straight plate shape, it has less contact area with the adjacent two connecting plates 111, and when it is in an arc plate shape, it can only fit one of the connecting plates 111, and when it fits the other connecting plate 111, it may still have less contact area. In this case, the sealing glue and the rotating plate 113 have less area, and some positions may not be completely bonded, that is, there may be a problem of air leakage. To avoid this problem, please refer to Figure 10 , the rotating plate 113 includes two arc edge plates 1131, and when the arc edge plates 1131 fit the sealing plate 116, they form a circular outer wall in combination.

[0057] That is, the arc edge plate 1131 can tightly adhere to the sealing plate 116, and since the two arc edge plates 1131 are the same shape, in this case, when the rotating plate 113 rotates in the opposite direction, it will tightly adhere to the sealing plate 116 on the other side, ensuring the tightness of the adhesion on both sides and ensuring the sealing state during daily use.

[0058] Since the steering pipe 12 is a pipe for assisting steering, it is commonly used at the position of steering the straight pipe 11, and due to the limitation of its structure, it cannot be operated with the structure of the rotating plate 113, so the length of the steering pipe 12 is as short as possible, and this way is to ensure that the steering pipe 12 can be easily disassembled during subsequent comprehensive cleaning, and this setting not only ensures that the steering pipe 12 is easy to clean, but also ensures that the pipe length of the steering pipe 12 after disassembly is low, and the cleaning speed is faster.

[0059] In one embodiment, please refer to Figure 5 With Figure 9 , the steering pipe 12 has a flange plate 121 at both ends, and the outer end face of the flange plate 121 is provided with a protruding part 123, which is clamped into the inner wall of the straight pipe 11.

[0060] The flange plate 121 is connected with the positioning ring 112, and is fixed by penetrating the screw and nut, and the protruding part 123 can directly penetrate into the inner wall of the straight pipe 11, thereby forming a quick insertion function, which not only facilitates positioning, but also provides support to the steering pipe 12 in the form of insertion, facilitating the fixation of the steering pipe 12.

[0063] S1: Injecting desulfurizing agent into the inside of the desulfurizing tower 30 through the desulfurizing agent storage bin 20 to desulfurize the flue gas, and sending the desulfurized flue gas into the settling chamber 40 for settling.

[0064] S2: The settled flue gas is sent into the dust remover 50 for dust removal, and finally discharged through the induced draft assembly 60.

[0065] Steps S1 and S2 are steps for treating flue gas, which are disclosed in the prior art, so in this embodiment, they are not explained in detail, and on this basis, the embodiment further proposes to clean the inner wall of the ventilation pipe 10, specifically using the ventilation pipe 10 of any one of embodiment 1, and performing step S3.

[0066] S3: When there are more attachments inside the ventilation pipe 10, the rotating plate 113 is controlled to rotate to drive the side with attachments to rotate to the outside of the straight pipe 11.

[0067] The attachments are rotated to the outer surface by rotating the rotating plate 113, that is, two end faces of the rotating plate 113 form two different direction circular tube structures, when cleaning is needed, the two end faces are switched, so that one end face can always form a pipe, and the end face forming the outer wall of the pipe can be directly cleaned.

[0068] S4: The outer surface of the straight pipe 11 is cleaned by the cleaning device, and the next work is waited.

[0069] The cleaning method is usually directly by flushing or by brushing, which is selected according to the setting position of the ventilation pipe 10 and the application environment.

[0070] Before step S4 is executed, the following steps are also needed to be executed:

[0071] A waste collecting box is arranged below the straight pipe 11 to collect the attachments falling off during cleaning.

[0072] That is, the attachments are collected by the waste collecting box, so that the attachments do not fall off to affect the workshop environment.

[0073] The above is only a preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
