Description

Technical Field

[0001] The utility model specifically relates to a collision-range-increasing device for capturing sparks, and belongs to the technical field of dust removal devices. Background Art

[0002] During the welding and grinding process, a large amount of harmful substances such as exhaust gas, grinding sparks and welding slag will be generated, which poses a great threat to the health of workers. Therefore, large dust removal equipment is usually arranged in the welding workshop, and connected to the welding station through a branch pipe to realize dust removal during the welding and grinding process; existing dust removal equipment, such as China Patent Authorization Announcement No.: CN221557868U, discloses a dry filter cartridge dust collector. When working, the cleaning circle is driven up and down by the first motor, and the cleaning circle is driven to rotate by the second motor, so that the cleaning circle cleans the filter cartridge by lateral rotation, and the multi-dimensional cleaning operation The operation makes the cleaning more effective and the subsequent work efficiency around the filter cartridge is maintained at a higher state; however, the dust collector cannot be applied to high-temperature environments. During the welding and grinding process, the temperature of the grinding sparks reaches 600 to 800°C, and the welding sparks are at 200 to 300°C. When the high-temperature slag enters the dust collector, the spark temperature is too high and it is easy to ignite the filter material, resulting in smoldering accidents inside the dust collector. Therefore, the existing dry filter cartridge dust collector cannot cool the sparks; the current collection form either increases the size of the dust collector host or has a higher investment cost, and there is no targeted solution at present. Utility Model Content

[0003] In order to solve the above problems, the utility model proposes a collision-range-extended Mars capture device, which not only plays a filtering role, but also increases the range of Mars, thereby realizing Mars capture and filtration and reducing the internal energy of Mars.

[0004] The collision range extension spark capture device of the utility model comprises a dust removal body, an air inlet and an exhaust port are arranged on the dust removal body, a filter element is arranged between the air inlet and the exhaust port; a negative pressure fan connected to the exhaust port is arranged inside the dust removal body, and further comprises:

[0005] The capture chamber seat comprises a sealing plate, the sealing plate is fixed to the outside of the air inlet by bolts, the inner side of the sealing plate is integrally formed with a square tube cavity, the square tube cavity is movably engaged with the air inlet; the sealing plate is provided with a flange opening directly in front of the square tube cavity;

[0006] A fire baffle, which is a frame-shaped structure with two hollow sides, and is fixed to the inner surface of the sealing plate by bolts;

[0007] A metal spiral mesh, wherein the metal spiral mesh is provided with multiple layers, the multiple layers of the metal spiral mesh are mutually pressed; the mesh holes of the adjacent layers of the metal spiral mesh are arranged in a staggered manner; the metal spiral mesh is filled between the fire baffle and the sealing plate, and the two sides of the metal spiral mesh are in contact with the inner surface of the square tube cavity;

[0008] The two sides of the fire baffle and the inner wall of the square tube cavity form an air intake channel, and the air intake channel is communicated with the inner side of the dust removal body.

[0009] When the collision-range extended-range spark capture device is working, the sparks enter the dust collector body through the negative pressure, and the distance for the sparks to reach the filter unit inside the dust collector body is extended, so that the sparks consume internal energy, thereby achieving the purpose of lowering the temperature, thereby preventing the excessive temperature of the sparks from igniting the filter material; specifically: under the negative pressure of the fan, the sparks approach the dust collector body, and a metal spiral mesh is set at the air inlet of the dust collector body, which can increase the collision probability of large-particle sparks and change the trajectory of the sparks, thereby increasing their movement range. At the same time, for the spark particles entering the metal spiral mesh, due to the spiral intersection of the metal spiral mesh, the inside of the metal spiral mesh is more irregular, forming a three-dimensional interception of the spark, causing the sparks to collide multiple times and increasing the movement range of the sparks; for smaller sparks, when they pass through the metal spiral mesh, they are first intercepted by the fire baffle, and because the flange and the air inlet channel are misaligned; when the smaller sparks enter the air inlet channel, the smaller sparks need to re-enter the metal spiral mesh; and then enter the air inlet channel through the metal spiral mesh, thereby reducing the temperature of the sparks.

[0010] Furthermore, a collecting hopper is connected to the bottom of the fire baffle; an isolation mesh is provided between the collecting hopper and the fire baffle; a slot engaged with the collecting hopper is provided at the bottom of the square tube cavity; a rotary valve is fixed at the bottom of the collecting hopper; the bottom of the rotary valve is connected to the discharge hopper of the dust removal body;

[0011] During operation, sparks can be intercepted and filtered by the metal spiral mesh and fire baffle, and enter the collecting hopper through the isolation mesh plate. Then, the valve plate of the rotary valve is used as a receiving bin to intercept sparks. When the valve plate receives a certain amount of sparks, the rotary valve rotates one position to allow the sparks to enter the closed surface position of the rotary valve. After the sparks cool down, the rotary valve rotates one position again to guide the sparks from the bottom of the rotary valve into the discharge hopper of the dust removal body, which can filter the sparks.

[0012] Furthermore, a vibrating motor is provided on the top of the fire baffle, and the slag collected by the metal spiral mesh can be vibrated into a collecting hopper through regular vibration of the vibrating motor.

[0013] Furthermore, a dust removal hole array is provided on the fire baffle; the aperture of the dust removal hole array is 0.5~0.8mm; when the dust removal hole array is used for dust removal, it can intercept large and small particles of sparks and introduce them into the collecting hopper. At the same time, dust smaller than the particle size of small particles of sparks can pass through the dust removal hole array smoothly and finally be filtered by the filter unit inside the dust removal body.

[0014] Furthermore, the flange port is connected to a dust suction pipe, one end of the dust suction pipe is connected to the dust removal body, and the other end is connected to a grinding and welding station.

[0015] Furthermore, a plurality of holes are opened on the periphery of the flange mouth, and a nut body is welded to the inner surface of the sealing plate at the hole body; when the dust suction pipe is installed, the mounting flange of the dust suction pipe is connected with the flange mouth, and then the bolts are passed through the mounting flange and screwed and tightened with the nut body to realize the connection between the dust suction pipe and the dust removal body.

[0016] Furthermore, the dust removal body is composed of a dry filter cartridge dust collector. By increasing the range and capturing the sparks before the dry filter cartridge dust collector intakes air, the sparks can be captured and the internal energy of the sparks can be reduced.

[0017] Compared with the prior art, the collision-extended-range spark capture device of the utility model is installed at the air inlet of an ordinary dry filter cartridge dust collector without taking up too much space. By adding a metal spiral mesh and a fire baffle, when sparks enter the dust collector body, they need to undergo multiple collisions and increase the spark range to be collected, which can increase the range of the sparks and have a preliminary filtering effect, thereby reducing the internal energy of the sparks and reducing the probability of smoldering in the dust collector; and increasing the spark capture rate, which can automatically collect dust, thereby improving the smoke collection efficiency and reducing costs.
