Description

Technical Field

[0001] The utility model relates to the technical field of waste gas collection, and particularly relates to a waste gas treatment and collection device. Background Art

[0002] Waste gas is generally the gas emitted from industrial production. Since many current waste gases are harmful to human health, many enterprises adopt waste gas collection devices for centralized treatment during the production and manufacturing process;

[0003] The existing waste gas treatment and collection devices generally have a fan in the air suction box, and the fan inside the air collection box rotates to suck air, thereby collecting waste gas. However, this waste gas treatment method can only absorb waste gas from a single direction, with a narrow absorption range and prone to causing air flow disorder in some factory areas, resulting in waste gas overflow.

[0004] Therefore, there is an urgent need for a collection device that can fully absorb waste gas in all directions and at multiple angles. Summary of the Utility Model

[0005] The utility model provides a waste gas treatment and collection device to achieve the above functions.

[0006] The utility model is realized by the following technical solutions:

[0007] A waste gas treatment and collection device includes a base body and an air suction device installed on the base body. The base body is a square box structure, including a top plate and an outer shell. A driving component is installed in the outer shell, and the air suction device is installed above the driving component;

[0008] The driving component includes a motor connected to a speed reducer. The output shaft of the speed reducer is fixed to a vertical air suction cylinder above through a coupling;

[0009] The air suction device includes an air suction cylinder and a turbo fan clamped on the outer wall of the air suction cylinder. The air suction cylinder passes through a round hole on the top plate and extends out of the base body. The turbo fan is connected to a lower limit clamping block through a clamping foot at its bottom, and the air suction cylinder is rotatably connected to the top plate through a bearing.

[0010] Further, the air suction cylinder is hollow, with a closed top and a circular shape. Several staggered air suction holes are provided on the part of the air suction cylinder protruding above the top plate, and the air suction holes are arranged in a spiral pattern. Several air delivery holes are provided on the part of the side wall of the air suction cylinder below the top plate, and each air delivery hole is located on the same horizontal plane. The air delivery holes are in a gas collection cavity fixed to the bottom of the top plate.

[0011] Further, the air collecting cavity is penetrated up and down by an air suction cylinder. A filter screen is provided at one end of the air collecting cavity. A filter plate is provided on the other side of the filter screen. The filter plate is fixed in the square groove of the top plate and can slide up and down for replacement. Three guiding fans are provided on the other end face of the filter plate. Both the guiding fans and the filter plate are located in the filtering cavity at the bottom of the top plate. The wind direction formed by the rotation of the guiding fans is from the air collecting cavity to the filtering cavity.

[0012] Further, two round holes are provided on the rear end face of the filtering cavity, and exhaust pipes are installed at the round holes. The exhaust pipes communicate with the air collecting cavity and pass through the outer shell of the base body.

[0013] Further, the turbine fan has a double-ring structure, including an inner ring and an outer ring connected by inner ring fan blades. A number of outer ring fan blades are installed on the outside of the outer ring, which can provide a downward suction force when rotating. Six L-shaped clamping feet with the same structure are provided at the bottom of the inner ring;

[0014] The limiting clamping blocks are two semi-circular rings, which are connected and clamped by bolts. An L-shaped limiting groove is provided at the top of each semi-circular ring for fixing the clamping feet. After the clamping feet extend into the limiting groove, they can rotate counterclockwise for side fitting. The air suction cylinder rotates clockwise to ensure the stability of the connection between the turbine fan and the limiting clamping blocks.

[0015] Further, a control panel is installed on the outer shell, and a controller for connecting each actuator is built in the control panel. A wire hole through which internal and external cables can pass is also provided on the outer shell.

[0016] Further, an air suction cover installed on the top plate is also provided outside the air suction cylinder. A number of neatly arranged air permeable holes are provided on the air suction cover.

[0017] The beneficial effects of the present utility model are as follows:

[0018] Through the cooperation of the turbine fan and the air suction cylinder, this device can form a "tornado"-shaped vortex when absorbing waste gas. While driving the waste gas in all directions around to enter, it can further accelerate the absorption rate of the waste gas in the center, playing a role of central absorption of the air flow around, and effectively preventing the waste gas from disorderly overflowing to other positions.
