The spark catcher has the advantages of simple structure, smaller airflow resistance, simple cleaning and maintenance, long service life, no moving part and no need of additional power supply due to the adoption of a reasonable design structure.
The above purpose of the invention is realized by the following technical scheme:
a spark catcher for a dust removal system of an automobile welding workshop comprises a shell, a damping plate, a gate valve and a dust collection barrel; the bottom of the shell is provided with a gate valve, and the bottom of the gate valve is provided with an ash collecting barrel; the two ends of the shell are respectively provided with an air inlet and an air outlet, and the edges of the two sides of the shell are provided with flanges; a damping plate is arranged in the shell and is a corrugated mesh damping plate;
furthermore, the corrugated mesh damping plate is formed by bending a mesh plate, the diameter of holes of the mesh plate is phi 6-phi 8, the hole spacing is 10-15mm, the holes are arranged in a triangular shape, the aperture ratio is 25-33%, and the bending angle is 90-120 degrees.
Furthermore, the installation and arrangement intervals of the two adjacent corrugated mesh damping plates are equal to the wave height formed by bending, and the wave crest of one damping plate is superposed with the wave trough of the adjacent damping plate in the axial direction of the shell.
Furthermore, the size of the interface between the air outlet and the air inlet is designed according to the caliber size of the pipeline of the dust removal system, and corresponds to the caliber size of the pipeline of the dust removal system.
Compared with the prior art, the invention has the beneficial effects that:
the spark catcher provided by the invention is a spark blocking and extinguishing device, can effectively catch and extinguish high-temperature particle dust and sparks entering a dust removal system pipeline under the condition of not influencing the normal operation of a purification and dust removal system, and eliminates the risk of fire and explosion caused by the caught sparks of the system. The spark catcher has the advantages of simple structure, smaller airflow resistance, simple cleaning and maintenance, long service life, no moving part and no need of additional power supply due to the adoption of a reasonable design structure. The spark catcher is generally arranged at the front end of a dust remover or the rear end of a smoke dust catching port, and can fully collide, buffer, cool and extinguish high-temperature smoke dust or sparks entering the spark catcher through a wave-shaped net plate which is internally designed according to a certain arrangement rule.
Drawings
FIG. 1 is a front view of the spark arrestor of the present invention.
Fig. 2 is a side view of the spark arrestor of the present invention.
Fig. 3 is a sectional view a-a of fig. 1.
In the figure: 1. the device comprises a shell, 2 parts of a gate valve, 3 parts of an ash collecting barrel and 4 parts of a damping plate.
Detailed Description
The invention is described in more detail below with reference to specific examples, without limiting the scope of the invention. Unless otherwise specified, the experimental methods adopted by the invention are all conventional methods, and experimental equipment, materials, reagents and the like used in the experimental method can be obtained from commercial sources.
Example 1
A spark catcher for a dust removal system of an automobile welding workshop is generally arranged at the front end of dust removal equipment and comprises a shell 1, a damping plate 4, a gate valve 2 and a dust collection barrel 3 as shown in figures 1-3; the bottom of the shell 1 is provided with a gate valve 2, and the bottom of the gate valve 2 is provided with an ash collecting barrel 3; an air inlet and an air outlet are respectively arranged at two ends of the shell 1, and flanges are arranged at the edges of two sides of the shell 1; a damping plate 4 is arranged inside the shell 1, and the damping plate 4 is a corrugated mesh damping plate;
the size of the interface of the air outlet and the air inlet is designed according to the caliber size of the pipeline of the dust removal system and corresponds to the caliber size of the pipeline of the dust removal system.
The shell 1 is connected with a pipeline system through connecting flanges respectively, and certain connection sealing performance is guaranteed.
The corrugated mesh damping plate 4 in the spark catcher is formed by bending a mesh plate, the diameter of the mesh plate is phi 6, the distance between the holes is 10mm, and the bending angle is 105 degrees, namely the angle alpha in figure 3;
the installation and arrangement intervals of the adjacent two corrugated mesh damping plates 4 are equal to the wave height formed by bending, the wave crest of one corrugated mesh damping plate is overlapped with the wave trough of the adjacent corrugated mesh damping plate in the axial direction of the shell, and the line B-B in the figure 3 is the coincident line of the wave crest and the wave trough;
in a certain range, the bending angle of the corrugated mesh damping plate 4 is increased, the running wind resistance of the spark arrestor can be relatively reduced, the installation distance of the corrugated mesh damping plate 4 can also be reduced, the number of the corrugated mesh damping plates 4 required by the spark arrestor with the same size or air volume can be increased, and after the number is increased to a certain number, the wind resistance can be changed and increased. For example, the wind resistance at an angle α of 90 ° may be slightly higher than 100 °;
as shown in figure 3, the arrow indicates the trend of the air flow passing through the spark catcher, when the air flow passes through the spark catcher, most of the air flow does not move along a straight line due to the shape of the corrugated mesh damping plate 4, high-temperature dust particles and spark particles collide with the corrugated mesh damping plate 4 in the spark catcher under the action of inertia, and the mesh does not block the air flow and only delays the deceleration to a certain extent, so that the spark catcher can play the roles of buffering the air flow and catching and extinguishing sparks.
I in fig. 3 shows that part of the air flow may slowly pass through the meshes of the corrugated mesh damping plate 4.
The embodiments described above are merely preferred embodiments of the invention, rather than all possible embodiments of the invention. Any obvious modifications to the above would be obvious to those of ordinary skill in the art, but would not bring the invention so modified beyond the spirit and scope of the present invention.
