Description

Technical Field

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

[0002] Currently, the waste gas generated during the production of wood processing lines contains a large amount of sawdust. After being separated 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 is prone to generating additional dust during bagging, and if the sawdust temperature is too high, there is also a fire hazard. Utility Model Content

[0003] The purpose of this utility model is to address the above-mentioned shortcomings by providing a wood processing waste gas treatment device.

[0004] This utility model includes a cyclone separator and a sedimentation tank. The inner wall of the inlet end of the sedimentation tank is a feeding slope, and the inner wall of the outlet end of the sedimentation tank is a discharging slope. A feeding sleeve is provided on the inlet end of the sedimentation tank, and a scraper conveyor is provided at the bottom of the sedimentation tank. The feeding end of the scraper conveyor is located on the feeding slope, and the discharging end of the scraper conveyor is located on the discharging slope. The bottom discharge port of the cyclone separator is connected to the feeding sleeve.

[0005] The scraper conveyor is equipped with a set of rubber push plates, and drainage gaps are formed between two adjacent rubber push plates.

[0006] The feed sleeve is installed at the inlet end of the sedimentation tank via a sleeve bracket.

[0007] Spiral blades are installed inside the sedimentation tank located on one side of the feed sleeve.

[0008] A discharge guide cloth is installed at the bottom of the outlet end of the sedimentation tank.

[0009] An extension rod is installed on each side of the outlet end of the sedimentation tank, and a shielding cloth is installed at the end of the extension rod.

[0010] A discharge guiding area is formed between the discharge guiding cloth and the shielding cloth.

[0011] The extension mounting rod is an L-shaped mounting rod with a set of mounting holes at the top of the shielding cloth. Bolts pass through the mounting holes to fix the top of the shielding cloth to the extension mounting rod.

[0012] A set of reinforcing rods are arranged in sequence inside the top opening of the sedimentation tank.

[0013] The cyclone separator is mounted on a frame above the sedimentation tank, and an exhaust fan is connected to the top air outlet of the cyclone separator via a pipe.

[0014] The advantages of this invention are: the wood chips discharged from the cyclone separator are sent to the sedimentation tank to be moistened and then discharged in a concentrated manner, without generating dust, and the wood chips are moistened to eliminate the fire hazard.

Furthermore, if terms such as "first" or "second" appear in the description of this invention, they are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0022] As shown in the attached figure, this utility model includes a cyclone separator 1 and a sedimentation tank 2. The inner wall of the inlet end of the sedimentation tank 2 is a feeding slope, and the inner wall of the outlet end of the sedimentation tank 2 is a discharging slope. A feeding sleeve 3 is provided on the inlet end of the sedimentation tank 2. A scraper conveyor 4 is provided at the bottom of the sedimentation tank 2. The feeding end of the scraper conveyor 4 is located on the feeding slope, and the discharging end of the scraper conveyor 4 is located on the discharging slope. The bottom discharge port of the cyclone separator 1 is connected to the feeding sleeve 3.

[0023] A set of rubber push plates is installed on the scraper of the scraper conveyor 4, and a drainage gap is formed between two adjacent rubber push plates.

[0024] The feed sleeve 3 is installed at the inlet end of the sedimentation tank 2 via a sleeve bracket.

[0025] A spiral blade 5 is installed inside the sedimentation tank 2 located on one side of the feed sleeve 3.

[0026] A discharge guide cloth 6 is installed at the bottom of the outlet end of the sedimentation tank 2.

[0027] An extension 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 rod 7.

[0028] A discharge guiding area is formed between the discharge guiding cloth 6 and the shielding cloth 8.

[0029] The extension mounting rod 7 is an L-shaped mounting rod. The top of the shielding cloth 8 has a set of mounting holes. Bolts pass through the mounting holes to fix the top of the shielding cloth 8 to the extension mounting rod 7.

[0030] A set of reinforcing rods 9 are arranged in sequence inside the top opening of the sedimentation tank 2.

[0031] 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.

[0032] 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.
