Description

Technical Field

[0001] This utility model relates to the field of pulse dust collectors, and more particularly to an insertion-type pulse dust collector. Background Technology

[0002] Pulse jet dust collectors are a new type of high-efficiency baghouse dust collector that uses compartmented, off-pipe pulse jet cleaning technology. They are mainly used for industrial dust control in fields such as power, building materials, metallurgy, and chemicals. Their structure includes a dust hopper, inlet and outlet ducts, filter chambers, filter bags, and a pulse cleaning mechanism. They are characterized by low air leakage, low energy consumption, and long filter bag life.

[0003] A search revealed Chinese Patent Publication No. CN215916743U, which discloses an insert-type pulse dust collector. The collector includes a main body housed within an insert-type housing. This housing is an integrated structure. Several pulse solenoid valves are arranged side-by-side on one outer wall of the housing. Each solenoid valve is fixed and connected to an air storage tank below it. The air storage tank is supported by two support frames. A pulse controller is located below the air storage tank and is connected to all the pulse solenoid valves via cables. An air inlet is located at the bottom of the housing, and an exhaust outlet is located at the top. An inspection door is located on the left outer wall of the air storage tank, and an induced draft fan is located on the right outer wall. The induced draft fan is connected to the exhaust outlet. A pressure gauge is located below the air storage tank and is connected to the tank via an air pipe. This utility model provides an insert-type pulse dust collector that can be directly plugged into the top of the powder silo without the need for a ventilation network duct or a dust unloading device. It is easy to install, use, and maintain. This utility model is mainly used for dust control in silos and bins during the transportation of bulk materials in the grain industry.

[0004] The above-mentioned device has the following defects: relying solely on the pulse airflow to impact the filter bag, it is difficult to completely remove the dust on the surface of the filter bag, especially the dust in the gaps and folds on the surface of the filter bag. The residual dust will gradually accumulate, leading to a decrease in the filtration efficiency of the filter bag, an increase in the operating resistance of the equipment, and affecting the long-term stable operation of the equipment. Therefore, an insertion pulse dust collector is proposed to solve the above problems. Utility Model Content

[0024] 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.

[0025] Reference Figures 1-2 This utility model provides an embodiment of an insert-type pulse dust collector, including a cabinet 1. The cabinet 1 serves as the main outer shell of the pulse dust collector, providing installation space and support structure for internal components, accommodating and protecting the internal components, and ensuring the stability and sealing of the entire device, allowing the dust removal process to take place in a relatively enclosed environment. A cabinet door 2 is detachably connected to the front surface of the cabinet 1. The design of the cabinet door 2 facilitates maintenance, repair, replacement of parts, and cleaning of the interior of the cabinet 1 by operators, and is a key component connecting the operator to the interior of the cabinet 1. The left side of the cabinet 1 can be... The air inlet pipe 3 is detachably connected and used to introduce dust-containing gas into the dust collector. It serves as the inlet channel for the dust-laden gas to enter the treatment system. Its design and connection method affect the gas inflow speed and direction, thus impacting dust removal efficiency. An exhaust pipe 4 is detachably connected to the bottom right side of the cabinet 1. Filtered and cleaned gas exits the dust collector through the exhaust pipe 4, ensuring smooth exhaust and achieving gas circulation and emission functions. Its position and structural design are crucial for smooth exhaust. A cleaning component 5 is located at the bottom left surface of the cabinet 1, and a cleaning assembly 5 is fixedly installed at the bottom of the cabinet 1. The collection box 10 and the cabinet 1 have an air jet plate 8 fixedly installed on the upper side of the left inner wall near the air inlet pipe 3. The main function of the air jet plate 8 is to evenly distribute the high-pressure pulse airflow released by the pulse valve 7 to each filter bag 94, so that each filter bag 94 can be subjected to effective pulse impact force, ensuring the consistency and comprehensiveness of the dust removal effect. At the same time, the structure and position design of the air jet plate 8 will also affect the direction and distribution of the pulse airflow, thereby affecting the stress on the filter bag 94 and the dust removal efficiency. The pulse valve 7 is fixedly installed at the axis of the upper surface of the air jet plate 8. When the pulse valve 7 receives a control signal, it quickly releases compressed air to generate pulses. The pulsed airflow is evenly injected into the filter bag 94 through the jet plate 8, causing the filter bag 94 to expand and shake instantly, thereby shaking off the dust attached to the outer wall of the filter bag 94, achieving the purpose of dust removal, ensuring the filtration efficiency and service life of the filter bag 94. The performance and working status of the pulse valve 7 directly affect the dust removal effect and overall performance of the dust collector. Two sets of sliding grooves 6 are provided on the left and right surfaces of the inner wall of the cabinet 1 near the lower side of the air inlet pipe 3. The sliding grooves 6 provide sliding space and guide path for the sliding strip 91 in the auxiliary component 9, so that the sliding strip 91 can slide smoothly in the sliding grooves 6. The auxiliary component 9 is installed inside the sliding grooves 6.

[0026] Reference Figures 2-4 The cleaning component 5 includes a slide rail 51, which provides a mounting and support base for components such as the motor 52, threaded rod 53, threaded sleeve 54, shelf 55, and limit rod 56. It also guides the movement of the shelf 55 and its components, ensuring that the cleaning sleeve 57 can clean the filter bag 94 and other components according to a predetermined path. The slide rail 51 is fixedly installed on the left surface of the cabinet 1. The motor 52 is fixedly installed on the upper surface of the slide rail 51. The motor 52 serves as a power source; the rotation of its output shaft provides power for the rotation of the threaded rod 53, driving the threaded sleeve 54 to move on the threaded rod 53, thereby moving the shelf 55 and the cleaning sleeve 57, achieving automated cleaning operation. The output of the motor 52... A threaded rod 53 is fixedly mounted on the shaft. The threaded rod 53 is driven by a motor 52 to rotate. The thread on its outer wall engages with a threaded sleeve 54, converting the rotational motion of the motor 52 into the linear motion of the threaded sleeve 54, thereby realizing the displacement of the shelf 55 and its components. The threaded sleeve 54 is threadedly connected to the outer wall of the threaded rod 53. The threaded sleeve 54 engages with the threaded rod 53 and can move axially under the rotation of the threaded rod 53. At the same time, its outer wall is slidably connected in the inner wall groove of the slide rail 51, playing a guiding and stabilizing role to ensure smooth movement. The outer wall of the threaded sleeve 54 is slidably connected in the inner wall groove of the slide rail 51. The shelf 55 is fixedly mounted on the right end of the threaded sleeve 54. 5 serves as the mounting carrier for the cleaning sleeve 57, and is detachably connected to the cleaning sleeve 57 via a through groove, facilitating the replacement and maintenance of the cleaning sleeve 57. It moves with the threaded sleeve 54, allowing the cleaning sleeve 57 to reach the filter bag 94 and other areas requiring cleaning. The upper surface of the placement plate 55 is detachably connected to the cleaning sleeve 57 via a through groove. When the placement plate 55 moves, the cleaning sleeve 57, under the action of the limiting rod 56, mechanically cleans the filter bag 94 and other components. Through contact and relative movement with the surface of the filter bag 94, it removes accumulated dust and impurities, restoring the filtration performance of the filter bag 94. The pad 58 increases the friction between the cleaning sleeve 57 and the filter bag 94, improving the cleaning effect. The inner wall of the cleaning sleeve 57 is embedded with... Multiple sets of pads 58 are inserted. The pads 58 work with the cleaning sleeve 57 to clean the filter bag 94 and other components. When the cleaning sleeve 57 contacts the filter bag 94, the pads 58 can penetrate into the gaps and folds on the surface of the filter bag 94 to more thoroughly remove dust and dirt, enhance the cleaning ability and effect of the cleaning sleeve 57, and at the same time play a certain role in buffering and protecting the filter bag 94. The lower surface of the slide 6 is fixedly connected to a limiting rod 56. The limiting rod 56 is connected through the lower surface of the placement plate 55. The limiting rod 56 plays a limiting and guiding role in the movement of the placement plate 55, preventing the placement plate 55 and its components from shifting or shaking during the movement, and ensuring accurate contact and cleaning effect between the cleaning sleeve 57 and the filter bag 94 and other components.

[0027] Reference Figure 2 , Figure 3and Figure 5 The auxiliary component 9 includes a slide bar 91, which is slidably connected to the inner wall of the slide groove 6. The slide bar 91 provides support and guidance, allowing the auxiliary plate 92 and its components to move smoothly within the slide groove 6, facilitating the installation, disassembly, and maintenance of the filter bag 94. The structure and sliding performance of the slide bar 91 also affect the flexibility and stability of the auxiliary component 9 within the cabinet 1. An auxiliary plate 92 is fixedly connected between two sets of slide bars 91. The auxiliary plate 92 is used to install and fix the positioning ring 95, providing support and positioning for the filter bag 94, ensuring the stability and correct installation position of the filter bag 94 during operation. The structural strength and rigidity of the auxiliary plate 92 are crucial to the load-bearing capacity and reliability of the filter bag 94. A positioning groove 93 is provided on the upper surface of the auxiliary plate 92, providing a slot position for the installation of the positioning ring 95, allowing the positioning ring 95 to be accurately installed on the auxiliary plate 92 and supporting the filter bag 94. The positioning groove 93 serves to further position and fix the filter bag 94 on the auxiliary plate 92, ensuring its firmness and stability. The shape and size of the positioning groove 93 are compatible with the positioning ring 95, guaranteeing a tight and reliable connection. The positioning ring 95 is detachably connected to the opening of the positioning groove 93. Through the cooperation of the positioning ring 95 and the positioning groove 93, the filter bag 94 is firmly installed on the auxiliary plate 92. Simultaneously, the positioning ring 95 can provide initial tension and positioning for the filter bag 94, ensuring it maintains a suitable shape and position during operation, facilitating gas filtration and dust removal. The structure and material of the positioning ring 95 have a certain impact on the installation strength and service life of the filter bag 94. The filter bag 94 is fixedly installed on the inner wall of the positioning ring 95. The main function of the filter bag 94 is to filter dust-laden gas, trapping dust on its outer surface, while clean gas passes through the filter bag 94 and exits through the exhaust pipe 4. The material, pore size, and filtration area of ​​the filter bag 94 directly affect the filtration efficiency and processing capacity of the dust collector. Simultaneously, the strength and durability of the filter bag 94 also affect the service life and maintenance cycle of the equipment. A cylindrical frame 96 is detachably connected to the inner wall of the filter bag 94. The cross-sectional area of ​​the outer wall of the cylindrical frame 96 matches the cross-sectional area of ​​the inner wall of the filter bag 94. The inner wall of the filter bag 94 and the outer wall of the cylindrical frame 96 are in contact, providing support for the filter bag 94 and preventing it from being crushed or deformed by the airflow during filtration, thus ensuring the shape and filtration area of ​​the filter bag 94. Furthermore, the structure and rigidity of the cylindrical frame 96 also affect the strength and stability of the filter bag 94, contributing to improved service life and filtration effect. Its smooth outer wall, in contact with the inner wall of the filter bag 94, facilitates the installation, disassembly, and cleaning of the filter bag 94.

[0028] Working principle:

[0029] Dust-laden gas first enters the cabinet 1 through the inlet pipe 3. Inside the cabinet 1, the slider 91 in the auxiliary component 9 slides within the slide groove 6, adjusting the position of the auxiliary plate 92 to position the filter bag 94 in a suitable working position. The cylindrical skeleton 96 inside the filter bag 94 provides support, ensuring the shape and filtration area of ​​the filter bag 94. When the dust-laden gas flows through the filter bag 94, dust is trapped on the outer surface of the filter bag 94, while clean gas passes through the filter bag 94 and enters the exhaust pipe 4 for discharge, completing the initial filtration process. As the filtration time increases... Dust gradually accumulates on the outer surface of the filter bag 94, affecting the filtration efficiency. At this time, the pulse valve 7 receives a control signal and quickly releases compressed air to generate a pulse airflow. This pulse airflow is evenly sprayed into the interior of the filter bag 94 through the jet plate 8, causing the filter bag 94 to expand instantly and shake. The inner wall of the filter bag 94 comes into contact with the outer wall of the cylindrical frame 96. The supporting role of the cylindrical frame 96 enables the filter bag 94 to withstand the impact force of the pulse airflow, while ensuring that the shape of the filter bag 94 is restored, shaking off the dust attached to the outer wall of the filter bag 94.

[0030] While pulse cleaning is in progress, the cleaning component 5 also works. The motor 52 drives the threaded rod 53 to rotate. The threaded rod 53 engages with the threaded sleeve 54, causing the threaded sleeve 54 to move along the slide rail 51. The threaded sleeve 54 drives the placement plate 55 to move. The cleaning sleeve 57 on the placement plate 55, under the limiting and guiding action of the limiting rod 56, mechanically cleans the filter bag 94 and other components. The pads 58 on the inner wall of the cleaning sleeve 57 can penetrate into the gaps and folds on the surface of the filter bag 94, more thoroughly removing dust and dirt and enhancing the cleaning effect. The dust that is shaken off falls into the collection box 10 under the action of gravity. The sealed design of the collection box 10 prevents the dust from flying again or spreading into the environment, ensuring the cleaning efficiency and environmental protection effect of the dust removal system. When the dust in the collection box 10 reaches a certain amount, the collection box 10 can be removed for centralized treatment and discharge.
