A cleaning door is provided on one side of the air outlet of the dust reduction box, and the cleaning door is located below the air outlet. The mounting plate can be slidably arranged in the purification chamber.

[0015] By adopting the above technical solution and setting a cleaning door, when the filter bags in the purification chamber have been used for filtering for a long time, a lot of dust and dust blocks will accumulate on the surface of the filter bags. Workers can open the cleaning door, take out the mounting plate and the filter bags on the mounting plate as a whole for cleaning, and then reinstall them after cleaning to maintain the cleaning effect of the filter bags.

[0016] Optionally, sliders are provided on both sides of the mounting plate, and slide grooves are provided on both sides of the purification chamber. The sliders can be slidably arranged in the slide grooves, and the mounting plate can be taken out from the cleaning door.

[0041] During the actual filtering process, the feed pipe 1 will collect wood chips and dust and enter the dust reduction box 32 from the air inlet box 5 and the air inlet in turn. The wood chips and dust are filtered by the filter component 7 in the dust reduction box 32. The wood chips are filtered by the filter component 7 and directly fall into the ash hopper 33, and are finally collected in the collection device 4. After the dust is filtered by the filter component 7, it is transferred from the air outlet to the exhaust pipe 9, and finally discharged to the outside under the action of the negative pressure fan 6.

[0042] refer to Figure 3 , 4 5. Specifically, in this embodiment, a partition plate 321 is provided in the dust reduction box 32 along its width direction to divide the interior of the dust reduction box 32 into two adjacent purification chambers 322, and the filter assembly 7 is installed in the purification chamber 322;

[0043] The filter assembly 7 includes a mounting plate 71, on which a plurality of mounting holes 72 are evenly spaced, a filter bag 73 is arranged in the mounting hole 72, a fixing ring 74 is arranged on the top of the filter bag 73, a bayonet 75 is arranged on the outer peripheral side of the fixing ring 74, and the bayonet 75 is used to snap into the inner peripheral side of the mounting hole 72, a support frame 76 is set in the filter bag 73, an air outlet seat 77 is arranged on the top of the support frame 76, the air outlet seat 77 is inserted into the filter bag 73, and the top of the air outlet seat 77 is covered on the fixing ring 74 The top is fixedly connected by locking screws, and the support frame 76 is fixedly connected to the outer peripheral side of the air outlet seat 77; a guide plate 323 is also provided in the purification chamber 322, and the guide plate 323 is located between the air inlet and the mounting plate 71, and the length of the guide plate 323 is smaller than the length of the filter bag 73, so that impurities such as wood chips and dust can move upward from the bottom of the filter bag 73, and an air outlet channel 324 is formed between the mounting plate 71 and the top of the purification chamber 322, and the exhaust duct 9 is connected to the air outlet channel 324.

[0044] In the actual process, when wood chips and dust enter the dust reduction box 32, that is, the purification chamber 322, from the air inlet, the guide plate 323 is provided at the air inlet. The guide plate 323 guides the wood chips and dust and filters them from the bottom of the filter bag 73 upward, so that the filtering path of the filter bag 73 for filtering the wood chips and dust is longer and the filtering effect is more sufficient.

[0045] refer to Figure 6 Specifically, in this embodiment, there are two air inlets, which are respectively located at one end of the two purification chambers 322 close to the air inlet box 5. The air inlet box 5 is provided with two guide seats 51 on one side close to the dust reduction box 32. An opening and closing member 52 for controlling the switch of the guide seats 51 is provided between the guide seats 51. The guide seats 51 are connected to the air inlets one by one;

[0046] An accommodating cavity 53 is provided between the two groups of guide seats 51 along their height direction, and an opening and closing member 52 is installed in the accommodating cavity 53. The opening and closing member 52 includes a first lifting drive member 521, a second swinging drive member and an opening and closing plate 522. The first lifting drive member 521 is fixedly installed on one side of the accommodating cavity 53 near the air inlet at one end near the air inlet, and a fixed block 54 is installed on the movable end of the other end of the first lifting drive member 521. The height of the fixed block 54 is consistent with the height of the accommodating cavity 53. The second swinging drive member is embedded in the fixed block 54. The second swinging drive member is hinged to the opening and closing plate 522 at one end away from the first lifting drive member 521, so that the opening and closing plate 522 can swing in a fan shape with the fixed block 54 as the center, and can swing to one side of any guide seat 51 to close the guide seat 51. The height of the opening and closing plate 522 is consistent with the internal depth of the air intake box 5.

[0047] In actual use, the opening and closing plate 522 has two use states. When only one purification chamber 322 is required for filtering, the first lifting drive member 521 located in the accommodating chamber 53 of the air intake box 5 drives the second swinging drive member and the opening and closing plate 522 to be pushed out from the accommodating chamber 53. After being pushed to a suitable position, the second swinging drive member drives the opening and closing plate 522 to swing, and the opening and closing plate 522 moves to one of the guide seats 51 before closing, so that only one purification chamber 322 is filtered. When two purification chambers 322 need to be filtered at the same time, the first lifting drive member 521 located in the accommodating chamber 53 of the air intake box 5 will shrink into the accommodating chamber 53, so that the second swinging drive member shrinks into the accommodating chamber 53 at the same time, and then the second swinging drive member is used to center the opening and closing plate 522, and the opening and closing plate 522 is partially inserted into the accommodating chamber 53 for fixing, so that the two guide seats 51 in the accommodating chamber 53 are both in the open and closed state.

[0048] refer to Figure 2 , 3Specifically, in the present embodiment, there are two air outlets, which are respectively located at one side of the two purification chambers 322 away from the air inlet, so that the gas in the air outlet channel 324 can enter the exhaust duct 9 from the air outlet for transfer, and a cleaning door 34 is provided on one side of the air outlet of the dust reduction box 32, and a transparent observation door panel 35 is provided in the middle of the cleaning door 34. The cleaning door 34 is located below the air outlet, and sliders 78 are provided on both sides of the mounting plate 71. Slide grooves 36 are provided on both sides of the purification chamber 322, and the sliders 78 can be slidably arranged in the slide grooves 36, so that the mounting plate 71 can be taken out from the cleaning door 34.

[0049] In addition, an escalator 8 is provided on the side of the frame 31 close to the cleaning door 34. Since the frame 31 has a certain height, the escalator 8 can make it easier for workers to approach the cleaning door 34, thereby opening the cleaning door 34 to clean the inside of the purification chamber 322, thereby improving the cleaning efficiency.

[0050] During the actual filtering process, a cleaning door 34 is set. After the filter bag 73 in the purification chamber 322 has been used for filtering for a long time, a lot of dust and dust blocks will accumulate on the surface of the filter bag 73. The worker can open the cleaning door 34 and use the sliders 78 on both sides of the mounting plate 71 to slide with the slide grooves 36 on both sides of the purification chamber 322 to make the mounting plate 71 and the filter bag 73 on the mounting plate 71 be taken out as a whole for cleaning. After cleaning, they can be reinstalled to maintain the cleaning effect of the filter bag 73.
