Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment devices, and particularly relates to a textile waste gas treatment device. Background Art

[0002] Textile waste gas generally refers to the waste gas generated in the production process of the textile industry (such as spinning, weaving, dyeing, post-finishing, etc.). To avoid the impact of these waste gases on the environment and cause pollution, people usually use textile waste gas treatment devices to treat textile waste gas.

[0003] Most of the existing textile waste gas treatment devices include a spraying mechanism (such as a spray tower) to pre-treat the waste gas to be treated. However, when the textile fabric bears forces such as friction and shear force from the textile work of textile equipment, some fibers will fall off from the fabric. Traction by the air flowing during the operation of the waste gas treatment equipment, these fibers enter the waste gas treatment device along with the waste gas. After being sprayed and moistened, these fibers gain weight and thus deposit at the bottom of the spraying mechanism. As the number of deposited fibers increases, it is easy to block the circulation system of the spraying mechanism, thereby affecting the normal operation of the waste gas treatment device. Summary of the Invention

[0004] The main object of the present invention is to provide a textile waste gas treatment device, aiming to solve the problem that fibers enter the interior of the treatment device along with the waste gas, are wetted by the spraying liquid, and deposit at the bottom of the device to block the circulation system.

[0005] To achieve the above object, the technical solution of the present invention is as follows: A textile waste gas treatment device includes a treatment box. The treatment box is provided with an air inlet pipe, and the air inlet pipe is provided with a filtering mechanism. The filtering mechanism includes a filtering interception plate and a cleaning structure for cleaning the filtering interception plate. The filtering interception plate is fixedly arranged in the air inlet pipe.

[0006] [[ID=2,4]]Furthermore, the air inlet pipe includes a bending part, and the end face of the filtering interception plate is parallel to the horizontal plane.

[0007] Furthermore, the cleaning structure includes a cleaning plate, a fiber discharge port, and a rotating component for controlling the rotation of the cleaning plate. A plurality of cleaning openings are provided on the cleaning plate, and each of the cleaning openings is evenly distributed in a circular pattern around the rotation center of the cleaning plate. The fiber discharge port is located on the array path of each cleaning opening.

[0008] Furthermore, the cleaning structure further includes a replenishing plate seat. A plurality of fiber storage plates are provided in the replenishing plate seat. Each fiber storage plate is provided with a fiber storage opening and a plurality of filter holes for matching with the filtering interception plate. Each of the cleaning openings respectively corresponds to and matches the filtering interception plate, the replenishing plate seat, and the fiber discharge port.

[0009] Furthermore, the projection surfaces of each of the cleaning openings and each fiber storage tray in the axial direction of the filter holes are all polygonal structures.

[0010] Furthermore, the rotating assembly includes a rotating motor, a driving gear, and a driven gear. The driven gear is an annular gear and is integrally formed with the cleaning plate, and the driving gear is linked with the output shaft of the rotating motor.

[0011] Furthermore, a discharge tray slideway is provided at one end of the fiber discharge port away from the cleaning plate, and the discharge tray slideway is inclined.

[0012] Furthermore, the projection surface area of each fiber storage tray in the axial direction of the filter holes is larger than the projection surface area of the filter intercepting plate in the axial direction of the filter holes, and the filter intercepting plate is in contact with the fiber storage tray.

[0013] Furthermore, the opening diameter of each fiber storage opening is larger than the inner diameter of the intake pipe.

[0014] Furthermore, the replenishing tray seat includes a replenishing tray channel, and each fiber storage tray is located in the replenishing tray channel, and the replenishing tray channel is perpendicular to the axial plane of the cleaning plate. The working principle and beneficial effects of the present invention are as follows: The technical solution of the present invention is to filter the fibers in the waste gas entering the processing tank along the intake pipe by providing a filtering mechanism at the intake pipe of the processing tank.

[0015] Specifically, the filtering mechanism in the present invention mainly includes a filter intercepting plate and a cleaning structure for cleaning the filter intercepting plate. The filter intercepting plate is fixedly arranged in the intake pipe to filter the waste gas, thereby intercepting the fibers in the waste gas and avoiding the fibers from entering the interior of the processing tank, fundamentally solving the problem of fiber deposition inside the processing tank; At the same time, by means of the cleaning effect of the cleaning structure on the filter intercepting plate, it is avoided that the intercepted fibers continuously accumulate to form a blockage of the filter intercepting plate body, ensuring the filtering stability of the filter intercepting plate.

[0019] The realization, functional features and advantages of the object of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0020] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. Embodiment

[0021] As Figures 1 - 2 shown, this embodiment proposes a textile waste gas treatment device, which mainly includes a processing box 1. The inside of the processing box 1 should have a spray chamber and a filtration chamber, and the spray chamber and the filtration chamber are interconnected. By allowing the waste gas to pass through the spray chamber and the filtration chamber in sequence, the treatment work is completed. The spray chamber should have a spray mechanism such as a water spray head, and the filtration chamber should have a number of filter meshes and other filtration structures. The specific internal structure of the processing box 1 and the waste gas treatment principle should be determined according to the model of the processing box 1 actually selected, and will not be elaborated in this embodiment.

[0022] At the same time, the processing box 1 is provided with an air inlet pipe 11, and the air inlet pipe 1 is fixedly arranged on the processing box 1. The air inlet pipe 11 is provided with a filter mechanism 2, that is, in this embodiment, by setting the filter mechanism 2 at the air inlet pipe 11, the fibers in the waste gas are prevented from entering the inside of the processing box 1 along with the waste gas.

[0023] Specifically, the filtering mechanism 2 mainly includes a filtering and intercepting plate 21 and a cleaning structure 22 for cleaning the filtering and intercepting plate 21. The filtering and intercepting plate 21 is fixedly arranged in the intake pipe 11 and located on the exhaust gas flow path, ensuring that the exhaust gas flowing along the intake pipe 11 can come into contact with the filtering and intercepting plate 21. With the filtering function of the filtering and intercepting plate 21, the fibers flowing along with the exhaust gas are intercepted in the intake pipe 11. Constrained by the pipe structure of the intake pipe 11, the fibers intercepted outside the treatment box 1 (outside the spray chamber) will not be scattered into the surrounding environment by the surrounding flowing air, ensuring the environmental hygiene of the surroundings.

[0024] The existence of the cleaning structure 22 facilitates the cleaning of the filtering and intercepting plate 21 located in the intake pipe 11. Through its cleaning function, it can prevent the number of fibers intercepted and filtered by the filtering and intercepting plate 21 from gradually increasing and accumulating over time, thereby blocking the filtering and intercepting plate 21 or even the intake pipe 11 and affecting the normal exhaust gas transportation work.

[0025] Specifically, the cleaning structure 22 in this embodiment includes a structure base, a cleaning plate 221, a fiber discharge port 222, and a rotating assembly 223 for controlling the rotation of the cleaning plate 221. The structure base is fixedly arranged on the treatment box 1, the cleaning plate 221 is rotatably connected to the structure base, and the fiber discharge port 222 is opened on the structure base. That is, the structure base serves as the base part of the cleaning structure 22, playing a role in supporting each component in the cleaning structure 22. Taking the structure base as a reference, the intake pipe 11 can be divided into a first pipe and a second pipe, and both the first pipe and the second pipe are interconnected with the inside of the structure base to prevent the existence of the structure base from blocking or closing the normal exhaust gas transportation path.

[0026] A number of cleaning ports 2211 are provided on the cleaning plate 221, and each cleaning port 2211 is evenly distributed in a circular pattern around the rotation center of the cleaning plate 221. The fiber discharge port 222 and the connection points of the intake pipe 11 and the structure base are all located on the array path of each cleaning port 2211. By starting the rotating assembly 223, the cleaning plate 221 rotates. During the rotation of the cleaning plate 221, each cleaning port 2211 on the cleaning plate 221 will be coaxially arranged and correspondingly matched with the fiber discharge port 222 and the intake pipe 11 in sequence. In this way, by rotating the cleaning plate 221, with the constraint of the wall (hole wall) of the cleaning port 2211 on the fibers in contact with it, the fibers accumulated on the filtering and intercepting plate 21 are brought to the fiber discharge port 222 for discharge, completing the cleaning work of the filtering and intercepting plate 21.

[0027] Moreover, when cleaning the filtering and intercepting plate 21 in this embodiment, as the angle of the cleaning plate 221 changes, it can automatically cut off and open the gas flow path of the intake pipe 11, making the opening and closing of the gas path naturally synchronized with the replacement action of the fiber storage tray 3, avoiding system mismatch problems caused by valve delay, and effectively improving the operation stability and continuous operation ability of this embodiment.

[0028] Meanwhile, to facilitate the fiber discharging operation, the rotation axis of the cleaning plate 221 is perpendicular to the horizontal plane, the end face of the cleaning plate 221 is parallel to the horizontal plane, and the fiber discharging port 222 is formed in the structure base by opening a hole in the structure base. In this way, when the fibers are moved to the fiber discharging port 222 under the action of the cleaning plate 221, they will be naturally discharged under the action of gravity, without the need to specially set up a dedicated grasping device to discharge the fibers, reducing the operating cost of this embodiment. Correspondingly, the end face of the filter intercepting plate 21 is parallel to the horizontal plane, and the air inlet pipe 11 includes a bent portion 111, that is, the air inlet pipe 11 has a bending point, so as to ensure that the filter intercepting plate 21 parallel to the horizontal plane can still cover the inner diameter of the air inlet pipe 11, ensuring the filtering effect and function of the filter intercepting plate 21. Embodiment

[0029] Based on Embodiment 1, as Figures 3 - 7 shown, the cleaning structure 22 in this embodiment further includes a supplementary plate base 224. A number of fiber storage plates 3 are provided in the supplementary plate base 224. Among them, the supplementary plate base 224 includes a supplementary plate channel 2241, and each fiber storage plate 3 is located in the supplementary plate channel 2241 and stacked in sequence. The supplementary plate channel 2241 is perpendicular to the axial plane of the cleaning plate 221; the supplementary plate base 224 is fixedly arranged on the structure base, and the supplementary plate base 224 is located above the cleaning plate 221; each cleaning port 2211 respectively corresponds to and matches the filter intercepting plate 21, the supplementary plate base 224, and the fiber discharging port 222. The height of the cleaning port 2211, the height of the cleaning plate 221, and the height of the fiber storage plate 3 are the same. In this way, as the cleaning plate 221 rotates, each fiber storage plate 3 in the supplementary plate base 224 will successively enter each cleaning port 2211, be located above the filter intercepting plate 21, and fall into the fiber discharging port 222, repeating in a cycle. This cycle process mainly relies on the action and influence of gravity, without the need to additionally set up a structure for controlling the fiber storage plate 3 to enter the cleaning port 2211, and only needs to ensure that there are enough fiber storage plates 3 in the supplementary plate base 224, effectively reducing the operating cost of this embodiment.

[0030] Each fiber storage tray 3 is provided with a fiber storage opening 31 and a plurality of filter holes 32 for matching with the filter interception plate 21 (filter holes on the filter interception plate 21). The fiber storage opening 31 is opened at the end of the fiber storage tray 3 away from the filter interception plate 21. The opening of the fiber storage opening 31 forms a cavity on the fiber storage tray 3 that can accommodate and accumulate fibers. In this way, the presence of the fiber storage disc 3 can cooperate with the filter interception plate 21 to play a double filtering role, improving the filtering and intercepting performance of the fibers, and at the same time can replace the cleaning plate 221 and the filter interception plate 21 to contact the intercepted fibers, thereby replacing the cleaning plate 221 and the filter interception plate 21 to directly face the exhaust gas, and bear most of the erosion from the corrosive components contained in the textile exhaust gas (such as acidic gases such as hydrogen sulfide), reducing the maintenance frequency of the core components of the filter mechanism 2 of this embodiment (cleaning plate 221, filter interception plate 21), and can be in operation for a longer time than embodiment 1; and due to the presence of the fiber storage disc 3, the intercepted fibers are effectively avoided from contacting the rotating gap between the cleaning plate 221 and the structural seat as the cleaning plate 221 rotates, thereby effectively preventing the intercepted fibers from being drawn into the rotating gap between the structural seat and the cleaning plate 221 during the rotation of the cleaning plate 221, thereby increasing the rotation resistance of the cleaning plate 221, and even jamming the cleaning plate 221.

[0031] In order to ensure that the double filtering effect formed by the fiber storage disk 3 and the filter interception plate 21 that cooperate with the filter interception plate 21 is sufficiently stable, the projected surface area of each fiber storage disk 3 in the axial direction of the filter hole 32 is larger than the projected surface area of the filter interception plate 21 in the axial direction of the filter hole 32. That is, in the direction of exhaust gas flowing along the intake pipe 11, the fiber storage disk 3 that matches the filter interception plate 21 can cover the filter interception plate 21, ensuring that the exhaust gas flowing along the intake pipe 11 can pass through double filtration, forcing the exhaust gas to first pass through the fiber storage disk 3 and then pass through the filter interception plate 21, forming a strict secondary filtration barrier.

[0032] The filter interception plate 21 and the fiber storage disk 3 abut against each other to avoid a large gap between them, so that the exhaust gas can quickly pass through the filter interception plate 21 and the fiber storage disk 3 and enter the processing box 1.

[0033] The opening diameter of each fiber storage opening 31 is larger than the inner diameter of the air inlet pipe 11. In this way, the fiber storage tray 3 that matches the air inlet pipe 11 and the filter interception plate 21 can retain the abutment relationship with the inner cavity of the structural seat, avoiding the fiber storage tray 3 from being skewed due to the impact of airflow, thereby ensuring the position stability of the fiber storage tray 3.

[0034] The projection surfaces of each cleaning port 2211 and each fiber storage tray 3 in the axial direction of the filter holes 32 are all polygonal structures. That is, by means of the hole axis fit between each fiber storage tray 3 and each cleaning port 2211, the fiber storage tray 3 is restricted to prevent the fiber storage tray 3 from rotating during the operation of this embodiment due to the force (such as the friction with the structure base when moving with the rotation of the cleaning plate 221), resulting in the misalignment of each filter hole 32 on the fiber storage tray 3 and each filter hole on the filter interception plate 21, and reducing the gas passing efficiency.

[0035] Meanwhile, a discharge tray slideway 4 is provided at one end of the fiber discharge port 222 far from the cleaning plate 221. The discharge tray slideway 4 is inclined. That is, the fiber storage tray 3 falling out of the fiber discharge port 222 and the fibers located in the fiber storage tray 3 will enter the discharge tray slideway 4 and slide along the discharge tray slideway 4 to the designated position to complete the discharging work. Compared with allowing the fiber storage tray 3 to directly drop vertically from the fiber discharge port 222, this method can greatly reduce the probability of damage to the fiber storage tray 3, facilitate the staff to recycle the fiber storage tray 3 and use it again, and further reduce the operation cost of this embodiment.

[0036] The rotation assembly 223 in this embodiment mainly includes a rotation motor 2231, a driving gear 2232, and a driven gear 2233. The driven gear 2233 meshes with the driving gear 2232, and the driven gear 2233 is a ring gear and is integrally formed with the cleaning plate 221 to ensure the connection strength between the driven gear 2233 and the cleaning plate 221. The driving gear 2232 is linked with the output shaft of the rotation motor 2231. The rotation motor 2231 is fixedly arranged on the structure base to ensure that the rotation motor 2231 can stably provide driving force. With the action of the gear transmission assembly, the output shaft of the rotation motor 2231 does not need to be coaxially arranged with the cleaning plate 221, thus avoiding the interference between the rotation motor 2231 and the replenishing tray seat 224, and at the same time, a stable transmission ratio can be maintained between the rotation motor 2231 and the cleaning plate 221, so as to control the rotation angle of the cleaning plate 221 through the rotation motor 2231.

[0037] The rotation motor 2231 in this embodiment is preferably a motor with high-precision control performance such as a servo motor, so as to further improve the accuracy of the rotation angle of the cleaning plate 221.
