Description

Technical Field

[0001] This utility model relates to the field of air pollution control technology, and in particular to an exhaust gas purification device for air pollution sources. Background Technology

[0002] Exhaust gases emitted by air pollution sources (such as industrial equipment) are a significant source of environmental pollution. Therefore, installing exhaust gas purification devices has become a necessary environmental protection measure.

[0003] Most existing exhaust gas purification devices adopt a structure that houses filter plates and filter elements within a cavity, purifying exhaust gas through physical filtration or chemical adsorption.

[0004] However, such devices reveal a core problem in practical applications: poor usability due to unreasonable structural design.

[0005] Specifically, the cavity of the purification device is usually a one-piece unit or a flange connection that requires cumbersome disassembly. When the internal filter plates and filter elements reach saturation and need to be maintained or replaced regularly, operators must spend a lot of time disassembling and assembling them, resulting in extremely poor maintainability.

[0006] At the same time, this unreasonable design is also reflected in the installation process. The connection between the device and external equipment (such as exhaust pipes) often relies on traditional bolt fixing, which is not only complicated and inefficient, but also makes it difficult to guarantee the stability and sealing of the connection.

[0007] This dual inconvenience in installation and maintenance severely affects the promotion, use, and long-term operational effectiveness of purification devices.

[0008] Therefore, this utility model proposes an exhaust gas purification device for air pollution sources to address the shortcomings of existing technologies. Utility Model Content

[0009] In view of the problems existing in the air pollution source exhaust gas purification device, such as the complicated and inefficient process of connecting with external equipment, and the difficulty in disassembling the cavity when the internal filter components need to be maintained or replaced, resulting in high maintenance costs and long time consumption, this utility model aims to provide an air pollution source exhaust gas purification device with an improved structure that can effectively solve the above problems.

[0010] This utility model provides an exhaust gas purification device for air pollution sources, including: a purification chamber, a filter plate disposed inside the purification chamber, a filter element disposed on the rear side of the filter plate, and an exhaust gas emission pipe fixedly connected to the top of the purification chamber.

[0011] The exhaust gas purification device for air pollution sources also includes maintenance components and installation components;

[0012] The maintenance component includes a first annular ring and a second annular ring fixed to the outer periphery of the purification chamber. The second annular ring has a screw hole. The maintenance component also includes a first stud, which passes through the first annular ring and is screwed into the screw hole to lock the first annular ring and the second annular ring together, thereby making the purification chamber a detachable structure.

[0013] The mounting assembly includes a second connecting seat, which has a first groove, a second groove located inside the first groove, and a second stud inside the first groove. The mounting assembly also includes a first connecting seat fixed to the bottom of the exhaust pipe, a trapezoidal connecting block disposed on the first connecting seat, a positioning pin passing through the first connecting seat, and a spring disposed inside the trapezoidal connecting block and abutting the positioning pin. The positioning pin can be inserted into the first groove and rotated into the second groove.

[0014] Preferably, the first annular ring and the second annular ring are respectively fixed to the outer periphery of different cavity sections of the purification chamber, so as to divide the purification chamber into a three-section detachable structure. When the first stud is loosened, the different cavity sections of the purification chamber can be separated so as to maintain the filter plate and the filter element inside.

[0015] Preferably, the second stud is used to securely connect the second connector to an external device, providing a stable base for subsequent installation of the mounting assembly.

[0016] Preferably, the spring is a compression spring, whose compression properties ensure that a stable elastic force can be continuously provided after the locating pin is engaged in the second groove.

[0017] Preferably, the spring generates elastic force when the positioning pin is engaged in the second groove to press the positioning pin firmly against the groove wall of the second groove, preventing it from accidentally loosening due to vibration.

[0018] Preferably, the second groove is a recessed groove formed from the groove wall of the first groove, which provides a clear limit for the rotation and engagement of the positioning pin.

[0019] Preferably, the trapezoidal connecting block is fixedly connected to the side wall of the first connecting seat, and the trapezoidal shape of the connecting block plays a role in pre-alignment and guidance when the first connecting seat and the second connecting seat are mated.

[0020] Preferably, the exposed end of the positioning pin is provided with a knob for rotation, which allows the operator to rotate the positioning pin by hand or with a tool to lock or unlock it.

[0021] Preferably, the first groove and the second groove together form an L-shaped groove. After the positioning pin is inserted into the first groove (the vertical groove of the L-shaped groove), it rotates into the second groove (the horizontal groove of the L-shaped groove), forming a quick and reliable bayonet-type locking.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model, by setting a maintenance component consisting of a first annular ring, a second annular ring, and a first stud, designs the purification chamber as a detachable multi-segment structure, which solves the problems of difficult cleaning and replacement of filter plates and filter elements inside the purification device in the prior art, and time-consuming and labor-intensive maintenance, and achieves the technical effects of quick disassembly and assembly, convenient maintenance, and ensuring long-term stable operation of the device.

[0024] 2. This utility model, by setting up an installation assembly consisting of a first connecting seat, a second connecting seat, a trapezoidal connecting block, a positioning pin, and a spring, and using a locking method in which the positioning pin is inserted and rotated into the groove, solves the problems of complex installation process, low efficiency, and unstable connection of the purification device and external equipment in the prior art, and achieves the technical effects of quick installation, accurate docking, and firm and reliable locking.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] Example:

[0033] Please refer to Figures 1 to 4 This utility model provides an exhaust gas purification device for air pollution sources, which aims to solve the problems of complex installation and docking process, low efficiency, and difficulty in disassembling the cavity when maintaining or replacing internal filter components in the existing technology, resulting in high maintenance costs and long time consumption.

[0034] like Figure 1 As shown, the exhaust gas purification device for air pollution sources includes a purification chamber 1, an exhaust gas emission pipe 2 fixedly connected to the top of the purification chamber 1, a maintenance component 3 for quick disassembly and maintenance of the purification chamber 1, a filter plate 4 and a filter element 5 installed inside the purification chamber 1, and an installation component 6 for docking and fixing the device with external equipment.

[0035] Purification chamber 1 serves as a treatment unit. Filter plate 4 and filter element 5 are both installed inside purification chamber 1. Filter element 5 is installed on the rear side of filter plate 4 along the direction of exhaust gas flow. Exhaust gas from external pollution sources enters purification chamber 1 and undergoes preliminary filtration by filter plate 4 and deep purification by filter element 5. The purified exhaust gas that meets the standards is discharged through exhaust gas emission pipe 2 at the top of purification chamber 1.

[0036] Please refer to Figure 2 The maintenance component 3 includes a first annular ring 301, a first stud 302, a second annular ring 303, and a screw hole 304. The first annular ring 301 is fixed to the outer periphery of the purification chamber 1, and the second annular ring 303 is fixed to the outer periphery of the purification chamber 1 and is arranged adjacent to the first annular ring 301. More specifically, the first annular ring 301 and the second annular ring 303 are respectively fixed to the outer periphery of different cavity sections of the purification chamber 1 to divide the purification chamber 1 into a three-section detachable structure. The second annular ring 303 is provided with a screw hole 304. The first stud 302 is detachably passed through the through hole of the first annular ring 301 and screwed into the screw hole 304, thereby realizing the locking of the first annular ring 301 and the second annular ring 303.

[0037] To address the problem of complex installation and docking processes in existing technologies, the technical solution of this embodiment is that the exhaust gas purification device for air pollution sources further includes an installation component 6, and the installation component 6 forms a specific structural fit and connection relationship with the purification chamber 1 and external equipment.

[0038] Please refer to the following carefully. Figure 3 and Figure 4 The following is a detailed description of installation component 6:

[0039] Mounting assembly 6 includes a second connector 605, which has a first groove 606 and a second groove 607 located inside the first groove 606. The second groove 607 is specifically a slot formed by recessing from the groove wall of the first groove 606, so that the first groove 606 and the second groove 607 together form an L-shaped groove structure. The second connector 605 also has a second stud 608 located inside the first groove 606. The second stud 608 is used to pass through the first groove 606 and fasten the second connector 605 to an external device.

[0040] Meanwhile, the mounting assembly 6 also includes a first connecting seat 604 fixed to the bottom of the exhaust pipe 2. The first connecting seat 604 is used to detachably connect with the second connecting seat 605. A trapezoidal connecting block 601 is provided on one side of the first connecting seat 604. Specifically, the trapezoidal connecting block 601 is fixedly connected to the side wall of the first connecting seat 604. A positioning pin 603 is provided in the hole of the first connecting seat 604. The exposed end of the positioning pin 603 is provided with a knob for rotation operation.

[0041] A spring 602 is provided inside the trapezoidal connecting block 601, and the end of the spring 602 abuts against the positioning pin 603. In the assembled state, the end of the positioning pin 603 is inserted into the first groove 606 and rotated into the second groove 607. At this time, the spring 602 is compressed and generates elastic force to tighten the positioning pin 603, ensuring high stability and anti-loosening ability of the connection between the first connecting seat 604 and the second connecting seat 605.

[0042] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0043] In a preferred embodiment, in order to facilitate the disassembly of the purification chamber 1, the first annular ring 301 and the second annular ring 303 are respectively fixed to the outer periphery of different cavity sections of the purification chamber 1. By locking and loosening the first stud 302, the purification chamber 1 is divided into a three-section detachable structure.

[0044] In a preferred embodiment, in order to achieve a secure installation of the device and the external equipment, the second connecting seat 605 is fastened to the external equipment by the second stud 608 thereon.

[0045] In a preferred embodiment, the trapezoidal connecting block 601 is fixedly connected to the side wall of the first connecting seat 604 for pre-docking guidance during installation.

[0046] In a preferred embodiment, the exposed end of the positioning pin 603 is provided with a knob for rotation operation to facilitate operator rotation.

[0047] In a preferred embodiment, in order to achieve the rotational locking of the positioning pin 603, the second groove 607 is a groove formed by recessing from the groove wall of the first groove 606, and the first groove 606 and the second groove 607 together form an L-shaped groove.

[0048] In a preferred embodiment, the spring 602 generates elastic force to press the positioning pin 603 against the positioning pin 603 when the positioning pin 603 is engaged in the second groove 607, thereby preventing the positioning pin 603 from loosening.

[0049] The working principle of this novel exhaust gas purification device for air pollution sources is as follows:

[0050] Once the device is installed, the exhaust gas from the external pollution source directly enters the purification chamber 1. After passing through the preliminary filtration of the filter plate 4 and the deep purification of the filter element 5, the qualified exhaust gas is discharged through the exhaust gas emission pipe 2 at the top of the purification chamber 1, completing the entire exhaust gas purification process.

[0051] During installation, the second connecting seat 605 is first fastened to the external equipment using the second stud 608. Then, the first connecting seat 604, which is fixed to the bottom of the purification chamber 1, is pre-connected by aligning the trapezoidal connecting block 601 on one side of the first connecting seat 605 with the interface. Next, the operator pushes the positioning pin 603, which passes through the hole in the first connecting seat 604, so that the other end of the positioning pin 603 is inserted into the first groove 606 of the second connecting seat 605. Then, the positioning pin 603 is rotated so that one end is embedded in the second groove 607 inside the first groove 606. At this time, the spring 602 in the trapezoidal connecting block 601 generates an outward elastic force, which firmly presses the positioning pin 603 into the second groove 607, thus achieving a tight lock between the first connecting seat 604 and the second connecting seat 605. The installation component 6 simplifies the installation and disassembly process of the device and the external equipment.

[0052] When the filter plate 4 and filter element 5 need to be cleaned or replaced, first loosen the first stud 302 connecting the first annular ring 301 and the second annular ring 303 to release the locking state of the two annular rings. Then, disassemble the purification chamber 1 upwards to fully expose the internal filter plate 4 and filter element 5 for maintenance. After maintenance, follow the reverse process to reset the purification chamber 1 and tighten the first stud 302 to relock the first annular ring 301 and the second annular ring 303. The maintenance component 3 enables quick disassembly and assembly of the purification chamber 1, greatly shortening the maintenance time.

[0053] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
