Description

Technical Field

[0001] The utility model relates to the field of waste gas treatment, in particular to a waste gas treatment mechanism for a glass fiber reinforced plastic spray tower. Background Art

[0002] FRP spray tower is a new type of environmentally friendly product, which has the characteristics of light weight, high strength, good corrosion resistance, etc. FRP spray tower generates a lot of waste gas during the spraying of FRP, and it is also necessary to connect the waste gas treatment mechanism to discharge the generated waste gas into the waste gas treatment mechanism for purification;

[0003] However, the existing waste gas treatment mechanism for FRP spray tower has the following shortcomings in the process of purifying waste gas: the waste gas contains a large number of particles. After the particles are filtered through the filter plate, the filter holes of the filter plate are easily saturated, that is, the particles are blocked in the filter holes of the filter plate, resulting in the waste gas passing through the filter plate. The speed is slowed down or even the filter plate can no longer filter the waste gas, reducing the waste gas treatment effect of the waste gas treatment mechanism. Utility Model Content

The injection mechanism is arranged at the upper end of the filter box, and the injection mechanism is located above the filter plate. A waste box is installed at the bottom of the filter box and is through-connected.

[0007] As a further improvement of the utility model, the jet mechanism includes an air intake interface, a main nozzle, a diversion pipe, and an injection mechanism.

[0008] As a further improvement of the utility model, the injection mechanism includes an anti-backflow mechanism, a support frame, a rotating rod, and a rotating blade. The bottom of the main nozzle and the diversion pipe are both provided with an anti-backflow mechanism and are through-connected. A support frame is welded inside the anti-backflow mechanism. The upper end of the rotating rod is installed in the middle of the support frame with a clearance fit. A rotating blade is welded at the lower end of the rotating rod, and the rotating blade is located at the lower end of the anti-backflow mechanism.

[0009] As a further improvement of the utility model, the anti-backflow mechanism includes a nozzle, a rotating block, a torsion shaft, and a one-way opening and closing piece. The bottoms of the main nozzle and the branch pipe are both nozzles and are through-connected. The lower end of the nozzle is hinged to the rotating block through the torsion shaft. The rotating block is welded to the middle part of the outer end of the one-way opening and closing piece. The one-way opening and closing piece is located at the lower end of the nozzle.

[0010] As a further improvement of the utility model, two filter plates are provided, and are vertically installed at the middle and upper ends of the interior of the filter box, and are installed in a snap-fit ​​manner with the interior of the filter box.

[0011] As a further improvement of the utility model, there are seven main nozzles and seven branch pipes, and seven and six injection mechanisms are arranged at the bottom of each main nozzle and branch pipe, and the seven main nozzles and seven branch pipes are installed in a right-angle cross array.

[0012] As a further improvement of the utility model, the support frame is in a "cross"-shaped structure, and a circular ring is provided in the middle, through which a clearance fit is performed with the rotating rod.

[0013] As a further improvement of the utility model, four one-way opening and closing pieces are provided, and the four one-way opening and closing pieces are sealed to form a disc-shaped structure, which just coincides with the outlet at the lower end of the nozzle.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods. Example

[0026] like Figure 1-Figure 5As shown, the utility model provides an exhaust gas treatment mechanism for a glass fiber reinforced plastic spray tower, which structure includes a main filter box C, a purification box J, an exhaust pipe P, a waste box F, and a sewage pipe G. The main filter box C is fixedly installed at the bottom of the purification box J and is connected through, the exhaust pipe P is embedded on the right side of the purification box J and is connected, the waste box F is installed at the bottom of the main filter box C and is connected through, and the sewage pipe G is embedded in the lower right end of the waste box F and is connected.

[0027] Among them, the main filter box C includes an air intake pipe c6, a filter box c5, a filter plate c8, and an injection mechanism c2. The air intake pipe c6 is arranged at the lower end of the left side of the filter box c5 and is through-connected. A filter plate c8 is installed at the middle and upper end of the filter box c5. The injection mechanism c2 is arranged at the upper end of the filter box c5, and the injection mechanism c2 is located above the filter plate c8. A waste box F is installed at the bottom of the filter box c5 and is through-connected.

[0028] Among them, the jet mechanism c2 includes an air intake interface c29, a main nozzle c27, a diverter pipe c23, and an jet mechanism c21. The air intake interface c29 is embedded in the upper left end of the filter box c5. The air intake interface c29 is welded to the left end of the main nozzle c27 and is through-connected. The main nozzle c27 is through-connected to the diverter pipe c23. The bottom of the main nozzle c27 and the diverter pipe c23 are both provided with a jet mechanism c21.

[0029] Among them, the injection mechanism c21 includes an anti-backflow mechanism 1z, a support frame 1g, a rotating rod 1x, and a rotating blade 1y. The bottoms of the main nozzle c27 and the diversion pipe c23 are both provided with an anti-backflow mechanism 1z and are through-connected. The support frame 1g is welded inside the anti-backflow mechanism 1z. The upper end of the rotating rod 1x is installed in the middle of the support frame 1g with a clearance fit. The lower end of the rotating rod 1x is welded with a rotating blade 1y, and the rotating blade 1y is located at the lower end of the anti-backflow mechanism 1z.

[0030] Among them, the anti-backflow mechanism 1z includes a nozzle z4, a rotating block z2, a torsion shaft z7, and a one-way opening and closing piece z9. The bottoms of the main nozzle c27 and the branch pipe c23 are both nozzle z4 and are through-connected. The lower end of the nozzle z4 is hinged to the rotating block z2 through the torsion shaft z7. The rotating block z2 is welded to the middle of the outer end of the one-way opening and closing piece z9. The one-way opening and closing piece z9 is located at the lower end of the nozzle z4.

[0031] Among them, there are two filter plates c8 in total, and they are vertically installed in the middle and upper end of the filter box c5. At the same time, they are installed in a snap-fitting manner with the inside of the filter box c5, so that the two filter plates c8 can double filter the exhaust gas inside the filter box c5, and the filter plates c8 are easy to disassemble and replace.

[0032] There are seven main nozzles c27 and seven branch pipes c23, and seven and six injection mechanisms c21 are provided at the bottom of each main nozzle c27 and branch pipe c23. The seven main nozzles c27 and seven branch pipes c23 are installed in a right-angle cross array, so that the forty-two injection mechanisms c21 are distributed in an array directly above the filter plate c8, so as to perform comprehensive injection cleaning work on the filter plate c8.

[0033] Among them, the support frame 1g is in a "cross" shape, and a ring is provided in the middle. The ring is clearance-matched with the rotating rod 1x, so that the rotating rod 1x can rotate smoothly at the center position of the support frame 1g, so that the rotating blades 1y can pressurize the ejected gas, increase the gas pressure acting on the filter plate c8, and ensure that the particles blocked in the filter holes of the filter plate c8 can be effectively removed.

[0034] Among them, there are four one-way opening and closing pieces z9, and the four one-way opening and closing pieces z9 are sealed to form a disc-shaped structure, which coincides with the outlet at the lower end of the nozzle z4. The one-way opening and closing piece z9 can seal the lower end of the nozzle z4 in one direction to ensure that the exhaust gas will not flow into the nozzle z4 when the gas filtered by the filter plate c8 flows upward into the purification box J.

[0035] The specific usage and function of this embodiment are as follows:

[0036] The utility model is connected to the smoke pipe of the glass fiber reinforced plastic spray tower through the air inlet pipe c6, so that the exhaust gas is discharged into the filter box c5 through the air inlet pipe c6. After entering the filter box c5, the exhaust gas continues to flow upward and contacts the filter plate c8. Through the two filter plates c8, the exhaust gas inside the filter box c5 can be double filtered, and the filter plate c8 is easy to be disassembled and replaced. The gas filtered by particles flows upward and is discharged into the purification box J. After the filter plate c8 has been filtered for a long time, the filter holes of the filter plate c8 are easily saturated, and the particles are blocked in the filter holes of the filter plate c8. At this time, the external air inlet box is connected through the air inlet interface c29, and the gas is discharged into the main nozzle c27. The seven main nozzles c27 and the seven branch pipes c23 are arranged in a right-angled array, so that the forty-two injection mechanisms c21 are arranged in an array just above the filter plate c8, which can filter the particles passing through. The filter plate c8 performs a comprehensive spray cleaning work. When spraying gas, it is discharged into the interior of the nozzle z4 through the gas, and the circular ring in the center of the support frame 1g is clearance-matched with the rotating rod 1x, so that the rotating rod 1x can rotate smoothly at the center position of the support frame 1g, so that the rotating blade 1y pressurizes the ejected gas, and increases the air pressure of the gas acting on the filter plate c8, ensuring that the particles blocked in the filter holes of the filter plate c8 can be effectively removed, and the gas exerts a downward spray force on the one-way opening and closing piece z9, so that the one-way opening and closing piece z9 rotates downward, and the nozzle z4 is controlled to have a one-way air outlet. When the air outlet stops, the reset elastic force applied by the torsion shaft z7 enables the one-way opening and closing piece z9 to unidirectionally seal the lower end of the nozzle z4, ensuring that the exhaust gas will not flow into the nozzle z4 during the process of the gas filtered by the filter plate c8 flowing upward into the purification box J.
