[0007] The top of the shell is also provided with a first dust cleaning mechanism, which cleans the inside of the shell through high-pressure airflow;

[0008] The shell is also provided with a second cleaning mechanism. When the first cleaning mechanism cleans the dust particles accumulated on the surface of the filter bag through the high-pressure airflow, the filter bag is struck by the second cleaning mechanism, causing the filter bag to shake.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Reference Figure 1-Figure 4 As shown, the present invention provides a container-type dust collector which is easy to maintain, including a shell 1, which is installed on a frame 2, an air inlet 3 is provided at one side end of the shell 1, an exhaust port 4 is provided at the other side end of the shell 1 relative to the air inlet 3, and an ash hopper 5 is provided at the bottom end of the shell 1. Gas enters the shell 1 from the air inlet 3, and is discharged from the exhaust port 4 after dust removal. The dust particles generated by filtration are collected from the ash hopper 5.

[0031] Furthermore, a snap-fit ​​plate 6 is provided on the top of the shell 1 , and the snap-fit ​​plate 6 facilitates maintenance of the interior of the shell 1 and replacement of the filter bag.

[0032] Furthermore, a first cleaning mechanism 7 is provided at the top of the shell 1. The first cleaning mechanism 7 cleans the interior of the shell 1 through a high-pressure airflow, thereby clearing dust particles accumulated on the surface of the filter bag.

[0033] Furthermore, a lifting valve mechanism 8 is also provided at the top of the shell 1. The lifting valve mechanism 8 includes a cylinder 81. The cylinder 81 is installed at the top of the shell 1. The piston rod end of the cylinder 81 is connected to the valve cover plate 82. An embedded plate 83 is provided below the valve cover plate 82. The embedded plate 83 has a valve hole 84 for the valve cover plate 82. The valve cover plate 82 is driven up and down by the cylinder 81 to close and open the valve hole 84.

[0034] In some embodiments, a sealing ring is further provided on the upper end surface of each valve hole 84, and a groove is provided in the sealing ring for placing the sealing ring. When the valve cover plate 82 moves downward and contacts the sealing ring, the sealing ring is squeezed by the valve cover plate 82 and deformed, thereby ensuring the airflow sealing effect.

[0035] Furthermore, a second cleaning mechanism 9 is also provided on the shell 1. When the first cleaning mechanism 7 cleans the dust particles accumulated on the surface of the filter bag through high-pressure airflow, the second cleaning mechanism 9 knocks the filter bag to make the filter bag shake, so that the dust particles are separated from the filter bag more quickly. Especially when processing relatively humid dust-containing gases, dust particles are easy to stick to the surface of the filter bag. Cleaning the dust particles on the surface of the filter bag only by high-pressure airflow cannot achieve the ideal effect, thereby reducing the cleaning cycle of the filter bag and reducing the cost of dust removal.

[0036] In a further embodiment, referring to Figure 4-Figure 5 An inclined baffle 10 is arranged in the shell 1 between the air inlet 3 and the exhaust port 4. The inclined baffle 10 extends downward from the air inlet 3 to the exhaust port 4. A vertical baffle 11 is arranged on the inner side of the inclined baffle 10. The vertical baffle 11 divides the shell 1 into two large chambers. The two large chambers include a first large chamber and a second large chamber. A filter bag holder 12 is arranged in the second large chamber. The filter bag holder 12 is used to install a filter bag (not shown in the figure). The first large chamber is divided into two small chambers by the inclined baffle 10, including a first small chamber and a second small chamber. The first small chamber is connected to the air inlet 3, and the second small chamber is connected to the exhaust port 4 and the valve hole 84.

[0037] Furthermore, a first row of ash holes 51 is provided below one side of the vertical baffle 11, and the first row of ash holes 51 is connected to the ash hopper 5. The first row of ash holes 51 is located below the inclined baffle 10, and the first small chamber is connected to the ash hopper 5 through the first row of ash holes 51. A second row of ash holes 52 is provided below the other side of the vertical baffle 11, and the second row of ash holes 52 is connected to the ash hopper 5. The second large chamber is connected to the ash hopper 5 through the second row of ash holes 52.

[0038] In this embodiment, the dust-containing gas enters the first small chamber from the air inlet 3, flows downward from the first row of ash holes 51 under the action of the inclined baffle 10, and then enters the second large chamber through the second row of ash holes 52. After being filtered by the filter bag, the dust particles are trapped on the outside of the filter bag, and the purified gas enters the inside of the filter bag, then enters the second small chamber through the valve hole 84, and is finally discharged from the exhaust port 4.

[0039] Furthermore, the exhaust port 4 is connected to an external induced draft fan system, and the flow of the dust-laden gas is accelerated by the operation of the external induced draft fan, thereby improving the filtering efficiency.

[0040] Furthermore, the first cleaning mechanism 7 includes an air tank 71, which is fixed to the shell 1 through an air tank bracket. The air outlet of the air tank 71 is connected to a pulse nozzle 72, and the other end of the pulse nozzle 72 extends to the top of the filter bag. A pulse valve 73 is also installed on the pulse nozzle 72.

[0041] In this embodiment, when it is necessary to clean the dust particles accumulated on the surface of the filter bag, the gas tank 71 and the pulse valve 73 are opened, and high-pressure gas is sprayed out from the gas tank 71, enters the shell 1 through the pulse nozzle 72, and then enters the inside of the filter bag to clean the dust particles accumulated on the surface of the filter bag. The dust particles enter the ash hopper 5 through the second row of ash holes 52, and the ash hopper 5 is opened to collect the dust particles.

[0042] In a further embodiment, referring to Figure 6-Figure 7 The second cleaning mechanism 9 includes a driving assembly, a transmission assembly and a cleaning assembly. The driving assembly includes a driving motor 91. The driving motor 91 is fixed to the shell 1 through a motor bracket. The driving motor 91 is connected to a driving shaft 92. A driving sprocket 93 is installed on the driving shaft 92. The driving shaft 92 is connected to a driving shaft bracket 94 through a bearing. The driving shaft bracket 94 is fixed to the shell 1. The driving sprocket 93 is connected to a driven sprocket 96 through a chain 95. The driven sprocket 96 is fixedly connected to a driving rod 97. The driving rod 97 is connected to a driving rod bracket through a bearing. The driving rod bracket is fixed to the shell 1. A plurality of cams 98 are fixed on the driving rod 97.

[0043] In this embodiment, the driving motor 91 is a reduction motor, which can operate at a lower speed while providing a greater torque.

[0044] In a further embodiment, the transmission assembly includes a top block 99 and a movable rod 910. The top block 99 is adapted to the cam 98. The end surface of the top block 99 close to the cam 98 is an arc surface. When the cam 98 rotates, the cam 98 can squeeze the top block 99. The friction between the top block 99 and the cam 98 can be reduced by setting the arc surface. The end surface of the top block 99 away from the cam 98 is fixedly connected to the movable rod 910. The end of the movable rod 910 close to the top block 99 is sleeved with a shaft sleeve 911. The movable rod 910 is slidably connected to the top block 99. The shaft sleeve 911 is fixed to the shell wall of the shell 1, and the shaft sleeve 911 passes through the shell wall of the shell 1. The end of the movable rod 910 away from the top block 99 is sleeved with a sliding sleeve 914, and the movable rod 910 is slidably connected to the sliding sleeve 914, and the sliding sleeve 914 is fixed to the vertical baffle 11. A support spring 912 is arranged between the top block 99 and the shaft sleeve 911, one end of the support spring 912 abuts against the top block 99, and the other end of the support spring 912 abuts against the shaft sleeve 911, and the support spring 912 is sleeved on the movable rod 910.

[0045] In this embodiment, when the cam 98 rotates to the end with the smallest diameter and contacts the top block 99, the support spring 912 is in a maximum telescopic state. When the cam 98 rotates to the end with the largest diameter and contacts the top block 99, the support spring 912 is in a minimum telescopic state. The cam 98 continuously rotates to realize reciprocating motion of the top block 99 and the movable rod 910 in the horizontal direction.

[0046] In a further embodiment, the cleaning component includes a fixed sleeve 913, which is sleeved on the movable rod 910 and fixed to the movable rod 910 by bolts to facilitate adjustment of the position of the fixed sleeve 913 on the movable rod 910. A plurality of mounting sleeves 915 are welded to the lower end of the fixed sleeve 913. A vertical rod 916 is inserted into the mounting sleeve 915, and the vertical rod 916 is fixed to the mounting sleeve 915 by a pin. A cross bar 917 is connected to the vertical rod 916 by a pin, and a plurality of through holes are provided on the vertical rod 916 to facilitate adjustment of the height of the cross bar 917. A plurality of spring clips 918 are fixedly connected to the upper end of the cross bar 917, and the spring clips 918 are perpendicular to the cross bar 917.

[0047] Furthermore, the spring piece 918 can be welded to the cross bar 917 or to the sleeve, and the sleeve is fixed to the cross bar 917 by bolts. The distance between two adjacent spring pieces 918 is the same as the distance between two adjacent filter bags, and the spring piece 918 is adapted to the position of the filter bag.

[0048] In this embodiment, the spring piece 918 is in the shape of an elongated strip and can be made of a metal material. The spring piece 918 is elastic and is preferably made of a stainless steel material.

[0049] In this embodiment, when the movable rod 910 moves back and forth in the horizontal direction, it drives the fixed sleeve 913, the vertical rod 916, the horizontal rod 917 and the spring piece 918 to move back and forth. Because the spring piece 918 is elastic, when the spring piece 918 moves back and forth, the spring piece 918 hits the filter bag, so that the dust particles on the surface of the filter bag can be quickly separated from the filter bag, and the dust particles sticking to the filter bag are broken and separated from the filter bag. Under the action of the high-pressure airflow, the filter bag is cleaned, which can greatly improve the cleaning efficiency of the filter bag.

[0050] The working principle of the present invention is as follows: dust-laden gas enters the first small chamber from the air inlet 3, flows downward from the first ash row hole 51 under the action of the inclined baffle 10, and then enters the second large chamber through the second ash row hole 52. After being filtered by the filter bag, the dust particles are trapped on the outside of the filter bag, and the purified gas enters the inside of the filter bag, and then enters the second small chamber through the valve hole 84, and is discharged from the exhaust port 4. When the first cleaning mechanism 7 cleans the dust particles accumulated on the surface of the filter bag by high-pressure airflow, the filter bag is knocked by the second cleaning mechanism 9, so that the filter bag is shaken, so that the dust particles are separated from the filter bag more quickly. In particular, when dealing with relatively humid dust-laden gas, the dust particles are easy to stick to the surface of the filter bag. The dust particles on the surface of the filter bag can not achieve the ideal effect by only using high-pressure airflow to clean the dust particles, thereby reducing the cleaning cycle of the filter bag and reducing the cost of dust removal.

[0051] The driving motor 91 is started to drive the driving shaft 92 and the driving sprocket 93 to rotate, and the driven sprocket 96 is driven to rotate through the chain 95, and the driving rod 97 and the cam 98 are driven to rotate. When the cam 98 rotates to the end with the smallest diameter and contacts the top block 99, the support spring 912 is in the maximum expansion state. When the cam 98 rotates to the end with the largest diameter and contacts the top block 99, the support spring 912 is in the minimum expansion state. The cam 98 rotates continuously to realize the top block 99 and the movable rod 910 in the horizontal direction. When the movable rod 910 reciprocates in the horizontal direction, it drives the fixed sleeve 913, the vertical rod 916, the horizontal rod 917 and the spring piece 918 to reciprocate. Because the spring piece 918 is elastic, when the spring piece 918 reciprocates, the spring piece 918 hits the filter bag, so that the dust particles on the surface of the filter bag can be quickly separated from the filter bag, and the dust particles sticking to the filter bag are broken and separated from the filter bag. Under the action of the high-pressure airflow, the filter bag is cleaned, which can greatly improve the cleaning efficiency of the filter bag.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
