DETAILED DESCRIPTION

[0027] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0028] Example:

[0029] Reference Figure 1 - Figure 6 The utility model discloses a fume bag filter, comprising a housing 1, a working chamber 6 for fume treatment is arranged inside the housing 1, an ash discharge port 7 for slag discharge is arranged at the bottom of the working chamber 6, and an air inlet pipe 8 and an air outlet pipe 9 are respectively installed on both sides of the housing 1;

[0030] Dust removal bags 2, which are provided in plurality and distributed in a matrix in the working chamber 6, and the plurality of dust removal bags 2 are connected to the housing 1 via a mounting assembly 10;

[0031] The pulse assembly 3 is composed of a pulse machine 31, a connecting pipe 32 and a pulse nozzle 33. The pulse machine 31 is installed on the outside of the housing 1 through a bracket, and the pulse nozzle 33 is installed in the working chamber 6 and above the dust bag 2. The pulse nozzle 33 is connected to the pulse machine 31 through a connecting pipe 32.

[0032] The dust shield 4 is connected to the inner wall of the working chamber 6 near the air inlet pipe 8 and is used to block the gas ejected from the air inlet pipe 8;

[0033] The sealing door 5 is sealingly mounted on one of the outer walls of the housing 1 .

[0034] In this embodiment, since the dust bag 2 is an important component of the bag filter, the installation of the dust bag 2 is particularly important. Figure 2 and Figure 3 It can be found that a working chamber 6 is opened in the shell 1, and an installation component 10 is arranged in the working chamber 6. The dust bag 2 is first fixed by using the installation component 10, and then the installation component 10 is installed in the working chamber 6. By installing the dust bag 2 externally, the installation of the dust bag 2 can be made more convenient, and the installation stability and installation tightness of the dust bag 2 can be better controlled, which can effectively improve the installation progress of the dust bag 2, thereby ensuring the dust removal effect of the bag dust collector.

[0035] And observe Figure 2 It can also be found that an air inlet pipe 8 for conveying smoke air and an air outlet pipe 9 for discharging clean gas are respectively connected to both sides of the shell 1. At the same time, a dust baffle 4 is fixedly connected to one side of the air inlet pipe 8 in the working chamber 6. When the smoke air is conveyed into the working chamber 6 through the air inlet pipe 8, the smoke particles with larger specific gravity will be blocked by the dust baffle 4 and fall to the dust discharge port 7 at the bottom of the working chamber 6. Some smoke particles can be filtered out from the air in advance, reducing the use intensity of the dust bag 2, thereby slowing down the clogging of the dust bag 2.

[0036] At the same time, a pulse component 3 is arranged on the top of the shell 1, so that after the bag dust collector is used, a pulse is generated by a pulse machine 31, and then a pulse is generated on the dust bag 2 through a connecting pipe 32 and a pulse nozzle 33, so that the dust particles adsorbed on the dust bag 2 are shaken off, thereby cleaning the dust bag 2.

[0037] In a further preferred embodiment of the present invention, Figure 4 and Figure 5As shown, the mounting assembly 10 includes a mounting plate 101, a mounting sleeve 102 and a clamping unit 103. The two sides of the mounting plate 101 are convexly formed with guide parts 11. The inner walls of the working chamber 6 located on both sides of the sealing door 5 are provided with guide grooves 12 for inserting the guide parts 11. The top of the mounting plate 101 is provided with a circular hole 13 for loading the dust bag 2. The mounting sleeve 102 fixed on the dust bag 2 is inserted into the circular hole 13. The front and rear sides of the mounting plate 101 are provided with clamping units 103 for fastening the mounting sleeve 102.

[0038] The clamping unit 103 includes a pressing plate 1031, an inserting rod 1032 and an extrusion block 1033. The pressing plates 1031 are symmetrically arranged on both sides of the mounting plate 101. Between the two pressing plates 1031, there are groups of inserting rods 1032 with the same number of rows as the dust bag 2. Each group of inserting rods 1032 is composed of two inserting rods 1032 that are fixedly connected to the corresponding pressing plates 1031. The two inserting rods 1032 are respectively arranged on both sides of the circular hole 13. The side of the inserting rod 1032 close to the circular hole 13 is fixedly connected with an extrusion block 1033.

[0039] The outer wall of the mounting sleeve 102 is provided with an annular groove 14 for inserting the extrusion block 1033 , and the bottom corners of the extrusion block 1033 are processed with inclined surfaces for guidance.

[0040] In this embodiment, circular holes 13 distributed in a matrix are provided on the mounting plate 101, so that the dust bag 2 can be positioned and installed on the mounting plate 101 according to the circular holes 13, which is convenient for the installation of the dust bag 2 and makes the installation of the dust bag 2 more convenient. The provided mounting sleeve 102 is used to fix the bag mouth of the dust bag 2 to prevent the dust bag 2 from falling off when it is installed in the circular hole 13, and can be used to improve the installation stability of the dust bag 2. Finally, after the dust bag 2 is installed, the mounting plate 101 is inserted into the working chamber 6. Afterwards, when the sealing door 5 is closed, the clamping unit 103 located on the front and rear sides of the mounting plate 101 is squeezed by the sealing door 5 and the inner wall of the working chamber 6, and the insertion rod 1032 on the pressure plate 1031 in the clamping unit 103 is inserted into the mounting plate 101, so that the extrusion block 1033 located on the insertion rod 1032 is pressed into the annular groove 14 on the mounting sleeve 102, and the extrusion block 1033 can be used to lock the mounting sleeve 102 in the circular hole 13, which can prevent the mounting sleeve 102 from falling out, thereby further improving the stability of the dust bag 2 after installation.

[0041] However, due to the existence of installation tolerance and the poor installation accuracy of the installation sleeve 102, the extrusion block 1033 may sometimes fail to be inserted into the annular groove 14. Figure 5As shown, the bottom corners in the forward direction of the extrusion block 1033 are processed with bevels, so that if the installation sleeve 102 is not installed smoothly, the bottom of the annular groove 14 will first contact the bevel of the extrusion block 1033, and then in the forward process of the extrusion block 1033, the bevel will apply downward pressure to the bottom of the annular groove 14, thereby flattening the installation sleeve 102 and inserting the extrusion block 1033 into the annular groove 14, which can effectively ensure the operating stability of the clamping unit 103, and at the same time, the operation of the clamping unit 103 is used to further ensure the installation stability of the dust bag 2.

[0042] In a further preferred embodiment of the present invention, Figure 4 As shown, the top protrusion of the installation sleeve 102 is formed with an annular portion 15 whose diameter is larger than that of the circular hole 13 , and the installation sleeve 102 is provided with a gasket 16 at the bottom of the annular portion 15 .

[0043] In this embodiment, since the installation sleeve 102 needs to be inserted into the circular hole 13, in order to prevent the installation sleeve 102 from falling out of the circular hole 13, the top of the installation sleeve 102 is provided with a Figure 4 As shown, an annular portion 15 having a diameter greater than that of the circular hole 13 is provided. The restriction of the annular portion 15 can be used to increase the installation stability of the installation sleeve 102 .

[0044] Due to the setting of the inclined surface of the extrusion block 1033, the annular groove 14 can be pressed down by the inclined surface when the extrusion block 1033 is inserted into the annular groove 14. Therefore, a gasket 16 is provided at the bottom of the annular portion 15 to increase the height of the annular groove 14, so that when the inclined surface presses down the annular groove 14, the gasket 16 will be compressed and deformed. The gasket 16 is used to increase the installation tightness of the mounting sleeve 102, and at the same time increase the connection tightness between the dust bag 2 and the mounting plate 101, which can effectively prevent unfiltered air from leaking through the connection between the dust bag 2 and the mounting plate 101, thereby avoiding dust accumulation at the bag mouth.

[0045] In a further preferred embodiment of the present invention, Figure 6 As shown, a circular groove 17 is formed on one side of the mounting plate 101 close to the pressing plate 1031 , and a spring for popping out the pressing plate 1031 is fixedly connected in the circular groove 17 .

[0046] In this embodiment, since the clamping unit 103 needs to be inserted into the mounting plate 101 to fix the mounting sleeve 102 when in use, and a gasket 16 is provided at the bottom of the annular portion 15 of the mounting sleeve 102, the clamping unit 103 will be pressed and stuck after being inserted into the mounting plate 101 to fix the mounting sleeve 102, affecting the removal of the clamping unit 103, thereby increasing the difficulty of disassembly when the dust bag 2 needs to be replaced, affecting the practicability of the mounting plate 101.

[0047] So observe Figure 6 It can be found that a circular groove 17 is opened on the outer wall of the mounting plate 101, and a spring is arranged in the circular groove 17, so that when the clamping unit 103 is inserted into the mounting plate 101, the spring will be squeezed, and when the mounting plate 101 is inserted into the working chamber 6, it will be squeezed by the sealing door 5 and the inner wall of the working chamber 6, so that the clamping unit 103 is inserted into the mounting plate 101, and the insertion of the clamping unit 103 will squeeze the spring and deform it. Subsequently, when the dust bag 2 needs to be replaced, the sealing door 5 is opened. At this time, the force used to support the clamping unit 103 disappears, and the spring can directly pop the clamping unit 103 out of the mounting plate 101, so that the clamping unit 103 is automatically disengaged, so that the replacement of the dust bag 2 will not be hindered, and the replacement efficiency of the dust bag 2 can be further improved.

[0048] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
