Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment equipment, specifically to a waste gas purification and collection system for wood processing. Background Technology

[0002] Currently, the waste gas generated during wood processing production lines contains a large amount of sawdust. After separation by a cyclone separator, the sawdust impurities are discharged downwards. The existing treatment method is to place ton bags at the bottom discharge port of the cyclone separator to directly receive the discharged sawdust. However, this method easily generates additional dust during bagging, and if the sawdust temperature is too high, there is also a fire hazard. Wet sawdust contains a certain amount of moisture, and the moisture easily flows out from the bottom after being piled up. There is a lack of a dedicated wet sawdust storage box.

The box 11 is located below the discharge port of the scraper conveyor 4.

[0030] A set of rubber push plates is provided on the scraper of the scraper conveyor 4, and a drainage gap is formed between two adjacent rubber push plates.

[0031] The feed sleeve 3 is installed at the inlet end of the sedimentation tank 2 via a sleeve bracket.

[0032] A spiral blade 5 is installed inside the sedimentation tank 2 located on one side of the feed sleeve 3.

[0033] A discharge guide cloth 6 is provided at the bottom of the outlet end of the sedimentation tank 2; an extension mounting rod 7 is provided on both sides of the outlet end of the sedimentation tank 2, and a shielding cloth 8 is provided at the end of the extension mounting rod 7; a discharge guide area is formed between the discharge guide cloth 6 and the shielding cloth 8; the extension mounting rod 7 is an L-shaped mounting rod, and a set of mounting holes are opened at the top of the shielding cloth 8. Bolts pass through the mounting holes to fix the top of the shielding cloth 8 to the extension mounting rod 7.

[0034] A set of reinforcing rods 9 are arranged in sequence inside the top opening of the sedimentation tank 2.

[0035] Cyclone separator 1 is mounted on top of sedimentation tank 2 via a frame, and an exhaust fan is connected to the top air outlet of cyclone separator 1 via a pipe.

[0036] The outer wall of the box 11 is provided with a grid-like reinforcing rib; the bottom surface of the box 11 is a slope, and the angle between the bottom surface of the box 11 and the horizontal plane is α, where α is 1-3°; the two ends of the handrail 15 are respectively provided with connecting plates, and are fixedly installed on the box wall of the box 11 through the connecting plates; a set of lifting rings 16 are respectively provided on the two side walls of the box 11.

[0037] The filter screen 13 has an arc-shaped cross-section. A set of filter screen mounting plates 17 are arranged from bottom to top on the inner wall of the housing 11. The filter screen 13 is vertically mounted on the set of filter screen mounting plates 17. The filter screen 13 is detachably mounted on the filter screen mounting plates 17 by bolts.

[0038] The base 12 has a locking universal wheel at one end and two locking universal wheels at the other end; the housing 11 is a rectangular box; the filter screen 13 has multiple sets of circular filter holes.

[0039] Example 1: Production water is injected into the sedimentation tank 2. Waste gas generated during wood processing enters the cyclone separator 1. After separation by the cyclone separator 1, wood chips fall downwards through the feed sleeve 3 into the sedimentation tank 2, where they are immersed in water. The spiral blades 5, driven by a motor, continuously rotate, agitating the floating wood chips at the top and causing them to sink. As the wood chips settle at the bottom of the sedimentation tank 2, the scraper conveyor 4 is started. A set of rubber pushers on the scraper of the scraper conveyor 4 continuously pushes the wood chips towards the outlet end of the sedimentation tank 2. When pushed to the upper part of the discharge slope, the wood chips detach from the water surface. Excess water in the wood chips flows back into the sedimentation tank 2 through drainage gaps. The dehydrated wet wood chips are discharged into the discharge guide area. The discharge guide cloth 6 and the shielding cloth 8 confine the discharged wet wood chips within a designated area to prevent splashing. The reinforcing rod 9 increases the overall structural strength of the sedimentation tank 2 and also prevents large objects from falling into the sedimentation tank 2.

[0040] The wet sawdust storage box is placed below the discharge port of the scraper conveyor 4. The discharge guide cloth 6 and the shielding cloth 8 are located inside the box body 11. The scraper conveyor 4 outputs sawdust from the sedimentation tank 2 into the box body 11. The sawdust accumulates inside the box body 11, and the moisture in the sawdust flows downwards along the bottom of the box body 11 to the filtration area 14. The filter screen 13 prevents sawdust from entering. When the sawdust is full, the worker grabs the handle 15 and pulls the box body 11 to the tilting position. The grid-like reinforcing ribs improve the overall strength of the box body 11. The box body 11 can be lifted upwards using the lifting ring 16 for easy transportation. The casters at the bottom of the base 12 are triangularly distributed, making turning easier when dragging.
