Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a waste gas treatment device with a protective structure for rubber processing. Background Technology

[0002] The first step in rubber processing is to mix various raw materials such as carbon black, rubber, and additives together in an internal mixer. Since waste gas is inevitably generated during the processing, a corresponding waste gas treatment device is needed to purify the waste gas.

[0003] In the prior art, Chinese utility model application number CN202420814865.0 discloses a rubber tire processing internal mixing waste gas treatment device that facilitates filter element replacement, including a treatment box and a box cover; four sets of fixing plates are fixedly connected to the left and right sides of the inner wall of the treatment box, and fixing blocks are slidably connected inside the fixing plates, and the fixing blocks are fixedly connected to the fixing frame; through the structural design of the fixing frame, the function of easily removing the fixing frame from the inside of the treatment box is realized, so as to facilitate the replacement of the filter element filled inside the fixing frame;

[0004] While the above-mentioned technical solutions facilitate filter replacement, the supply of exhaust gas needs to be interrupted during the filter replacement process to prevent exhaust gas leakage. This results in the inability to continue filtering the exhaust gas during the filter replacement process, reducing the purification efficiency of the exhaust gas. Therefore, we need to propose an exhaust gas treatment device with a protective structure for rubber processing. Utility Model Content

[0005] The purpose of this invention is to provide a waste gas treatment device with a protective structure for rubber processing. By setting an anti-leakage structure, the waste gas passage can be sealed during the filter element replacement process, thereby preventing waste gas leakage. At the same time, the external flow channel is opened to allow waste gas to circulate, thereby achieving a continuous filtration and purification effect on the waste gas. This improves the efficiency of filter element replacement while ensuring the purification efficiency of waste gas, thus improving the waste gas treatment efficiency and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste gas treatment device with a protective structure for rubber processing, comprising:

[0007] Multiple sets of equidistant filter boxes and a diversion pipeline connecting the multiple sets of filter boxes. Each set of filter boxes is equipped with a filter mechanism for purifying exhaust gas, and each set of filter boxes is equipped with a locking mechanism for pressing and positioning the filter mechanism. The pressing mechanism facilitates the assembly of the filter mechanism.

[0008] Each set of filter boxes is equipped with a leak-proof mechanism at the bottom to isolate exhaust gas when the filter mechanism is disassembled, and each set of filter boxes is equipped with a controller on the outside to control the opening and closing of the diversion pipeline, so as to achieve continuous flow of exhaust gas when the filter mechanism is replaced.

[0009] Preferably, the leak-proof mechanism includes an outer casing, a baffle, and multiple sets of springs. The multiple sets of springs are all fixedly connected to the bottom of the inner cavity of the outer casing, and the upper ends of the multiple sets of springs are all fixedly connected to the top of the inner cavity of the baffle. The baffle is slidably disposed in the inner cavity of the outer casing. A pressure rod is fixedly connected to the top of the inner cavity of the baffle. A limit switch coaxially disposed with the pressure rod is provided at the bottom of the inner cavity of the outer casing, and the limit switch is electrically connected to the controller. Multiple sets of connecting bolts are inserted into the outer casing and bolted to the filter box.

[0010] Preferably, the diversion pipeline includes a main pipe and multiple diversion branches connected to the main pipe. Each diversion branch is connected to an exhaust gas duct at the end away from the main pipe, and each diversion branch is equipped with a solenoid valve electrically connected to the controller.

[0011] Preferably, the filter box includes a box body, and both sides of the box body are provided with connecting covers that communicate with the exhaust gas duct.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model mainly utilizes the cooperation between the filter box, the diversion pipeline, the filtration mechanism, and the leak-proof mechanism. During the replacement of the filter mechanism, the leak-proof mechanism can block the exhaust gas in the corresponding filter box and control the opening of the diversion pipeline adjacent to the filter box that blocks the exhaust gas.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a waste gas treatment device with a protective structure for rubber processing, comprising:

[0025] Multiple sets of equidistant filter boxes 1, and a diversion pipeline 2 connecting the multiple sets of filter boxes 1. Each set of filter boxes 1 is equipped with a filter mechanism 3 for purifying exhaust gas, and each set of filter boxes 1 is equipped with a locking mechanism 4 for pressing and positioning the filter mechanism 3. The pressing mechanism facilitates the assembly of the filter mechanism 3.

[0026] Each filter box 1 is equipped with a leak-proof mechanism 6 at the bottom to isolate exhaust gas when the filter mechanism 3 is disassembled, and each filter box 1 is equipped with a controller 5 on the outside to control the opening and closing of the diversion pipeline 2, so as to realize the continuous flow of exhaust gas when the filter mechanism 3 is replaced.

[0027] The leak prevention mechanism 6 includes an outer casing 61, a baffle 63, and multiple sets of springs 64. The multiple sets of springs 64 are all fixedly connected to the bottom of the inner cavity of the outer casing 61, and the upper ends of the multiple sets of springs 64 are all fixedly connected to the top of the inner cavity of the baffle 63. The baffle 63 is slidably disposed in the inner cavity of the outer casing 61. A pressure rod 65 is fixedly connected to the top of the inner cavity of the baffle 63. A limit switch 66 is provided at the bottom of the inner cavity of the outer casing 61, which is coaxially arranged with the pressure rod 65. The limit switch 66 is electrically connected to the controller 5. Multiple sets of connecting bolts 62 are inserted into the outer casing 61 and bolted to the filter box 1. The springs 64 facilitate the baffle 63 to block the connecting chamber 14 of the filter box 1 when the filter mechanism 3 is disassembled, thereby preventing the flow of exhaust gas. At the same time, the pressure rod 65 disengages from the limit switch 66, which can control the opening of the solenoid valve 23 on the adjacent branch pipe 22 of the filter box 1 after the filter mechanism 3 is disassembled, thereby realizing the diversion and transportation of exhaust gas.

[0028] The diversion pipeline 2 includes a main pipe 24 and multiple diversion branches 22 connected to the main pipe 24. Each diversion branch 22 is connected to an exhaust gas duct 21 at the end away from the main pipe 24. Each diversion branch 22 is equipped with a solenoid valve 23 electrically connected to the controller 5. The flow of exhaust gas is controlled by opening and closing the solenoid valve 23, which facilitates continuous filtration of exhaust gas when replacing the filter mechanism 3 and improves the filtration efficiency of exhaust gas.

[0029] The filter box 1 includes a box body 11. Both sides of the box body 11 are provided with connecting covers 12 that communicate with the exhaust gas duct 21. The box body 11 has a connecting chamber 14 for connecting the two sets of connecting covers 12. The box body 11 has an installation through hole 13 for installing the filter mechanism 3. The upper end of the baffle 63 is positioned at the lower end of the installation through hole 13 when the exhaust gas flows. The connecting covers 12 can diffuse the exhaust gas introduced into the exhaust gas duct 21, increase the contact area between the filter element 37 and the exhaust gas, and thus improve the filtration effect of the exhaust gas.

[0030] The filter mechanism 3 includes a mounting frame 34 inserted into the mounting through hole 13. A limit frame 35 is provided at one end of the inner cavity of the mounting frame 34. A filter element 37 that abuts against the limit frame 35 is provided inside the mounting frame 34. A protective frame 38 is snapped onto one side of the mounting frame 34. Multiple sets of locking blocks 39 are fixedly connected to one side of the protective frame 38. A slot 36 is opened on one side of the mounting frame 34 for the multiple sets of locking blocks 39 to be inserted. By inserting the locking blocks 39 on the protective frame 38 into the slot 36, the filter element 37 can be pressed tightly into the mounting frame 34 and fit against the limit frame 35.

[0031] The filter element 37 is configured with a pre-filter layer, a medium-efficiency filter layer, and a high-efficiency filter layer from the near end of the exhaust gas to the exhaust gas outlet. The pre-filter layer can intercept larger particulate impurities in the exhaust gas, such as debris generated from rubber processing; the medium-efficiency filter layer can filter smaller dust particles and some harmful gas molecules; the high-efficiency filter layer can deeply adsorb and remove the remaining fine particles, harmful gases, and odors, achieving multi-stage purification. When the exhaust gas enters the filter box 1 in sequence, it is first pre-purified by the pre-filter layer to reduce the subsequent filtration pressure, and then passes through the medium-efficiency and high-efficiency filter layers in sequence, progressively improving the purification effect, making the exhaust gas treatment more complete, and improving the device's ability to remove different pollutants.

[0032] A sealing plate 31 is fixedly connected to the top of the mounting frame 34. A sealing gasket 33 is provided on the lower surface of the sealing plate 31, which contacts the upper surface of the housing 11. Both ends of the upper surface of the sealing plate 31 are inclined with pressure surfaces 32. The sealing gasket 33 can improve the sealing performance of the filter mechanism 3 after installation, and prevent exhaust gas from leaking out through the mounting hole 13.

[0033] The locking mechanism 4 includes two sets of locking bolts 44 threaded to the upper surface of the housing 11, and each set of locking bolts 44 is rotatably provided with a pressure block 41. The lower surface of the pressure block 41 is fixedly connected to two sets of insert rods 43 inserted into the housing 11, and a section of the lower surface of the pressure block 41 is provided with an inclined surface 42 that fits against the pressure surface 32. By rotating the locking bolts 44, the pressure block 41 can be driven to descend, and the inclined surface 42 of the pressure block 41 can be made to fit against the pressure surface 32 of the sealing plate 31, thereby facilitating the pressing of the sealing plate 31 and improving the stability of the filter mechanism 3 installation.

[0034] In use, the waste gas generated during rubber processing is sequentially introduced into multiple filter boxes 1 through the waste gas duct 21. Multiple filter mechanisms 3 filter and purify particles of different sizes in the waste gas. When it is necessary to replace the filter element 37 of a filter mechanism 3 in a certain filter box 1, the locking mechanism 4 of the corresponding filter mechanism 3 is removed, so that the filter mechanism 3 is slowly pulled out from the mounting through hole 13 of the box body 11. During the process of pulling out the filter mechanism 3, multiple spring parts 64 can lift the baffle 63 and fit it with the mounting frame 34 under the action of elastic force. At the same time, the pressure rod 65 disengages from the limit switch 66. The limit switch 66 transmits a signal to the controller 5, which controls the solenoid valve 23 on the branch pipe 22 adjacent to the filter mechanism 3 to be removed to open, so that the waste gas skips the filter box 1 of the filter mechanism 3 and directly enters the next filter box 1, realizing continuous filtration and purification of the waste gas, thereby improving the filtration and purification efficiency of the waste gas.

[0035] During the replacement and installation of filter mechanism 3, the mounting frame 34 is placed on the baffle 63 and pressure is applied to overcome the spring force, so that the mounting frame 34 is fully pressed into the mounting through hole 13. At this time, the pressure rod 65 in the baffle touches the limit switch 66, thereby causing the controller 5 to control the solenoid valve 23 on the adjacent branch pipe 22 of the filter box 1 where the filter mechanism 3 is installed to close, so that the exhaust gas is sent into the next filter box 1 through the connecting chamber 14. The filter mechanism 3 is then locked by the locking mechanism 4, thus realizing the replacement and installation of filter mechanism 3.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
