Description

Technical Field

[0001] This utility model relates to the field of bag filter technology, and more specifically, to an air inlet pipe for a bag filter. Background Technology

[0002] A baghouse dust collector is a highly efficient industrial dust removal device. Its main function is to remove suspended solid particles from the airflow to protect the environment and equipment. Dust-laden gas is introduced into the baghouse dust collector through an inlet duct. Some types of dust have strong settling or adhesion properties and easily settle in the duct. It is necessary for workers to disassemble the inlet duct and manually check and clean the accumulated dust in the inlet duct regularly to keep it unobstructed. If the system is not effectively cleaned or maintained, it may lead to blockage of the inlet duct, poor air intake, or dust backflow.

[0003] Existing baghouse dust collectors require manual regular inspection and cleaning of the inlet duct, which increases labor costs. If cleaning is not done in time, it may lead to blockage of the inlet duct, poor air intake, or dust backflow. In view of this, we propose a new baghouse dust collector inlet duct. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an air inlet pipe for a bag filter to solve the technical problem that the air inlet pipe of the current bag filter needs to be manually cleaned.

[0005] To solve the above technical problems, the present invention provides the following technical solution: an air inlet pipe for a bag filter, including an air inlet pipe assembly, a spring flap hinged to one end of the air inlet pipe assembly, a one-way flap slidably connected to the other end of the air inlet pipe assembly, and a mud removal knife fixedly installed on the side of the one-way flap opposite to the spring flap.

[0006] The air inlet duct assembly includes an air inlet duct body, a first air inlet nozzle is installed at one end of the air inlet duct body, an air outlet nozzle and a second air inlet nozzle are installed at the other end of the air inlet duct body, and a square box is connected to the opposite end of the second air inlet nozzle. The square box is fixedly installed at the other end of the air inlet duct body.

[0007] The spring-loaded flap is hinged to the root of the second air inlet, and the spring-loaded flap can be adapted to the inside of the second air inlet and the air outlet.

[0008] Preferably, a mud discharge nozzle is also installed at one end of the air inlet pipe body, and a sealing cap is detachably connected to the outside of the mud discharge nozzle;

[0009] A first limiting ring is installed inside the first air inlet nozzle, and a limiting half ring and a second limiting ring are also installed at the other end of the air inlet pipe body.

[0010] Preferably, the spring-loaded flap includes a first flap hinged to the inner root of the second air inlet via a first hinge, a spring body is mounted on the first flap, and the other end of the spring body is mounted on the inner sidewall of the second air inlet.

[0011] Preferably, the one-way flip cover includes a slip ring slidably connected in the air inlet pipe body, and the top of the slip ring facing the air outlet is hinged to a second flip cover by a second hinge.

[0012] Preferably, the descaling blade includes a ring blade fixedly mounted on a slip ring, and a plurality of dividing blades are installed in a circumferentially equidistant array inside the ring blade, and the cross-section of the ring blade is a right-angled triangle.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The present invention has a first air inlet nozzle installed at one end of the air inlet pipe assembly, and an air outlet nozzle and a second air inlet nozzle installed at the other end. When air is introduced through the second air inlet nozzle, the spring flap can be blown to block the air outlet nozzle, and the one-way flap and mud removal knife inside the air inlet pipe assembly are blown to the other end, automatically cleaning the dust and mud inside the air inlet pipe assembly and pushing it to the mud discharge nozzle, saving manpower.

[0025] like Figures 1 to 4 As shown, the present invention relates to an air inlet pipe for a bag filter, including an air inlet pipe assembly 1, a spring flap 2 hinged to one end of the air inlet pipe assembly 1, a one-way flap 3 slidably connected to the other end of the air inlet pipe assembly 1, and a mud removal knife 4 fixedly installed on the side of the one-way flap 3 opposite to the spring flap 2.

[0026] The air inlet duct assembly 1 includes an air inlet duct body 101. A first air inlet nozzle 102 is installed at one end of the air inlet duct body 101, and an air outlet nozzle 107 and a second air inlet nozzle 1010 are installed at the other end of the air inlet duct body 101. A square box 106 is connected to the opposite end of the second air inlet nozzle 1010. The square box 106 is fixedly installed at the other end of the air inlet duct body 101.

[0027] The spring-loaded flip cover 2 is hinged to the root of the second air inlet 1010. The spring-loaded flip cover 2 can be adapted to fit inside the second air inlet 1010 and the air outlet 107. One end of the air inlet pipe assembly 1 of this utility model is equipped with a first air inlet 102, and the other end is equipped with an air outlet 107 and a second air inlet 1010. Air enters through the second air inlet 1010, which blows the spring-loaded flip cover 2 to block the air outlet 107, and blows the one-way flip cover 3 and the mud removal knife 4 inside the air inlet pipe assembly 1 to the other end, automatically cleaning the air inlet. The ash and mud inside the pipe assembly 1 are pushed to the mud discharge nozzle 104, saving manpower. Air can be supplied to the bag filter as usual through the first air inlet nozzle 102 and the air outlet nozzle 107. The ring blade 401 with a right-angled triangular cross-section is designed to quickly remove the ash and mud inside the air inlet pipe body 101. The inclined surface of the ring blade 401 peels the ash and mud off the inner wall of the air inlet pipe body 101. Several dividing blades 402 can cut the ash and mud during the peeling process, making the ash removal smoother.

[0028] Furthermore, a mud discharge nozzle 104 is installed at one end of the air inlet pipe body 101. A sealing cover 105 is detachably connected to the outside of the mud discharge nozzle 104. After the ash and mud in the air inlet pipe assembly 1 are pushed to the mud discharge nozzle 104, the sealing cover 105 can be opened to quickly discharge the ash and mud.

[0029] The first air inlet nozzle 102 is equipped with a first limiting ring 103, and the other end of the air inlet pipe body 101 is also equipped with a limiting half ring 108 and a second limiting ring 109, which has a good limiting effect.

[0030] Furthermore, the spring-loaded flip cover 2 includes a first flip cover 201 hinged to the inner root of the second air inlet 1010 via a first hinge 203. A spring body 202 is mounted on the first flip cover 201, and the other end of the spring body 202 is mounted on the inner side wall of the second air inlet 1010. In different states, it can cover the second air inlet 1010 and the air outlet 107.

[0031] Furthermore, the one-way flip cover 3 includes a slip ring 301 slidably connected in the air inlet pipe body 101. The top of the slip ring 301 facing the air outlet 107 is hinged to the second flip cover 303 by the second hinge 302, which allows for one-way air intake.

[0032] Furthermore, the sludge removal blade 4 includes a ring blade 401 fixedly installed on the slip ring 301. Several dividing blades 402 are installed in a circumferentially equidistant array inside the ring blade 401. The cross-section of the ring blade 401 is a right-angled triangle. The several dividing blades 402 can cut ash and mud during the peeling process, making ash removal smoother.

[0033] Working Principle: This embodiment provides an air inlet pipe for a bag filter dust collector. In use, the air inlet pipe assembly 1 has a first air inlet nozzle 102 installed at one end and an air outlet nozzle 107 and a second air inlet nozzle 1010 installed at the other end. Air enters through the second air inlet nozzle 1010, blowing the spring-loaded flip cover 2 to block the air outlet nozzle 107. This blows the one-way flip cover 3 and the mud removal blade 4 inside the air inlet pipe assembly 1 to the other end, automatically cleaning the dust and mud inside the air inlet pipe assembly 1 and pushing it to the mud discharge nozzle 104, saving manpower. Air entering through the first air inlet nozzle 102 can normally be supplied to the bag filter dust collector through the air outlet nozzle 107. Furthermore, the ring blade 401, designed with a right-angled triangular cross-section, quickly removes dust and mud from the air inlet pipe body 101. The beveled surface of the ring blade 401 peels the ash and mud off the inner wall of the air inlet duct body 101. Several dividing blades 402 can cut the ash and mud during the peeling process, making ash removal smoother. When it is necessary to introduce dust-laden gas into the bag filter, the dust-laden gas is introduced from the first air inlet 102. Because the one-way flip cover 3 is adapted to the air inlet duct body 101, there is not enough space, and the one-way flip cover 3 cannot be opened inside the air inlet duct body 101. The dust-laden gas blows the one-way flip cover 3 and the mud removal knife 4 together toward the air outlet 107, causing the one-way flip cover 3 and the mud removal knife 4 to slide together until they abut against the limiting half ring 108. At this time, the other end of the one-way flip cover 3 is a square box 106, which has enough space to flip over. The dust-laden gas continues to blow open the one-way flip cover 3, causing the one-way flip cover 3 to be lifted upwards. Figure 3In the state shown, the spring body 202 pulls the first flip cover 201 to block the second air inlet 1010, and the dust-laden gas can be sent into the bag filter from the air outlet 107. When it is necessary to clean the dust and mud in the air inlet body 101, air is sent from the second air inlet 1010 to blow open the first flip cover 201 and press against the second limiting ring 109. At this time, the spring body 202 is stretched, and the sent-in gas continues to blow. Since the one-way flip cover 3 is hinged to the side of the slip ring 301 near the air outlet 107 and is limited by the slip ring 301, the one-way flip cover 3 can only flip to the side near the air outlet 107, and air is blown from the second air inlet 1010 to clean the dust-laden gas. Press the flip cover 3 against the slip ring 301, and blow the one-way flip cover 3 and the mud removal knife 4 together toward the first air inlet 102. The one-way flip cover 3 and the mud removal knife 4 together slide inside the air inlet pipe body 101. Through the design of the ring blade 401 with a right-angled triangular cross-section, the dust and mud in the air inlet pipe body 101 are quickly scraped off. At the same time, the inclined surface of the ring blade 401 makes the dust and mud peel off the inner wall of the air inlet pipe body 101. Several dividing blades 402 can cut the dust and mud during the peeling process, making the dust scraping smoother. After the dust and mud in the air inlet pipe assembly 1 are pushed to the mud discharge nozzle 104, the sealing cover 105 can be opened to quickly discharge the dust and mud (the bag dust collector is an existing product on the market).
