Description

Technical Field

[0001] The utility model relates to the technical field of flue gas collection, in particular to an efficient external overflow flue gas collection device. Background Art

[0002] The printing machine is mainly used for multi-color overprinting on clothing finished products and cut pieces, and belongs to a kind of screen printing machine. The printing machine is usually used in combination with a sizing machine. After the fabric is printed, it is sized by the sizing machine. At the same time, when the printing machine and the sizing machine are working, certain harmful gases will be generated. Part of these harmful gases will be treated by the gas treatment structure in the workshop, but there is still part of them that will overflow. Therefore, it is necessary to separately set up an external overflow flue gas collection device.

[0003] For example, the authorized announcement number "CN216262598U" is a pipeline collection system for flue gas. Through the flue gas collection box, flue gas collection is avoided, the quality of the production environment is improved, and the physical health of the staff is guaranteed. However, in the existing pipeline collection system for flue gas, since the equipment for recycling and collecting flue gas mainly relies on the smoking hood buckled above the printing machine main body, the smoking hood can only recycle the upward moving flue gas, and it cannot effectively absorb and collect the flue gas diffusing to the outside. Therefore, a part of the flue gas will leak out in the pipeline collection system for printing machine flue gas, thus reducing the flue gas collection efficiency of the pipeline collection system for flue gas. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem of poor collection efficiency of the existing pipeline collection system for flue gas, and to propose an efficient external overflow flue gas collection device.

[0009] Preferably, the printing flue gas suction structure includes an exhaust chamber and a drainage pipe. The exhaust chamber is fixedly connected to the top end of the smoke suction hood. A motor is fixedly installed at the top end of the exhaust chamber. The output shaft of the motor is fixedly connected to a rotating rod. The rotating rod is rotatably installed inside the exhaust chamber through a bearing. Two exhaust fan blades are fixedly sleeved on the outer wall of the rotating rod.

An air guide groove 55 is fixedly opened inside the two side frames 53. The air guide groove 55 can convey the flue gas entering the side plate frame 53 to the inside of the upper smoking hood 1. A cushion block 51 is fixedly installed at the bottom end of the side frame 53. The cushion block 51 is made of rubber material and has the effect of buffering and vibration reduction. Two support plates 52 are movably connected below the two cushion blocks 51. The support plates 52 are welded to both sides of the outer wall of the printing machine main body 2. The cushion block 51 can be placed downward on the top end of the support plate 52. In this way, the smoking hood 1 can be buckled on the top end of the printing machine main body 2. At the same time, the side plate frames 53 on both sides will stand vertically on both sides of the combustion chamber of the printing machine main body 2. A first filter screen 56 is fixedly installed on the inner side of the two side frames 53. Both the first filter screen 56 and the second filter screen 54 are made of stainless steel metal grid plates with a certain size of holes opened. Through the first filter screen 56 and the second filter screen 54, the flue gas can be normally inhaled, while solid impurities are isolated outside to reduce blockage. A second filter screen 54 is fixedly installed on the outer side of the lower end of the two side plate frames 53. The lower part of the first filter screen 56 is movably connected to the top end of the printing machine main body 2. The front ends of the two second filter screens 54 are arranged opposite to both sides of the printing machine main body 2. The top ends of the two air guide grooves 55 are fixedly communicated with the inside of the smoking hood 1;

[0023] Through the air guide groove 55, the flue gas entering the side plate frame 53 can be conveyed to the inside of the upper smoking hood 1. The cushion block 51 is made of rubber material and has the effect of buffering and vibration reduction. The support plates 52 are welded to both sides of the outer wall of the printing machine main body 2. The cushion block 51 can be placed downward on the top end of the support plate 52. In this way, the smoking hood 1 can be buckled on the top end of the printing machine main body 2. At the same time, the side plate frames 53 on both sides will stand vertically on both sides of the combustion chamber of the printing machine main body 2. Both the first filter screen 56 and the second filter screen 54 are made of stainless steel metal grid plates with a certain size of holes opened. Through the first filter screen 56 and the second filter screen 54, the flue gas can be normally inhaled, while solid impurities are isolated outside to reduce blockage. By arranging the absorption and collection structures for the combustion flue gas at the top and both sides, the situation of flue gas diffusion is reduced, and the flue gas collection efficiency of the external overflow flue gas high-efficiency collection equipment is improved.

[0024] The printed - smoke extraction structure 4 includes an exhaust chamber 42 and a drainage pipe 45. The exhaust chamber 42 is fixedly connected to the top of the smoking hood 1. A motor 43 is fixedly installed at the top of the exhaust chamber 42. When selecting the motor 43, a motor model that can meet the usage requirements can be chosen. The output shaft of the motor 43 is fixedly connected to a rotating rod 44. The rotating rod 44 is rotatably installed inside the exhaust chamber 42 through a bearing. When the printing machine main body 2 is burning, connect the power supply to start the motor 43. The motor 43 can drive the rotating rod 44 below to rotate. The rotating rod 44 can drive two exhaust fan blades 41 to rotate at high speed. The two exhaust fan blades 41 rotating at high speed can drive the air to generate suction to suck the smoke below into the smoking hood 1, and then discharge it through the drainage pipe 45 at the top. Two exhaust fan blades 41 are fixedly sleeved on the outer wall of the rotating rod 44. Two drainage pipes 45 are fixedly communicated with the top of the exhaust chamber 42. The bottom ends of the two exhaust fan blades 41 are arranged opposite to the upper side of the first filter screen 56. The lower sides of the two exhaust fan blades 41 are arranged opposite to the top ends of the air guide grooves 55.

[0025] Working principle:

[0026] When using the efficient external - overflow smoke collection device to absorb and collect the polluted and harmful smoke generated during the printing of the printing machine;

[0027] The smoke collection driving structure of the efficient external - overflow smoke collection device:

[0028] When the printing machine main body 2 is working, connect the power supply to start the motor 43. The motor 43 can drive the rotating rod 44 below to rotate. The rotating rod 44 can drive two exhaust fan blades 41 to rotate at high speed. The two exhaust fan blades 41 rotating at high speed can drive the air to generate suction to suck the smoke below into the smoking hood 1, and then discharge it through the drainage pipe 45 at the top.

[0029] The large - range efficient smoke collection structure of the efficient external - overflow smoke collection device:

[0030] Through the air guide grooves 55, the smoke entering from the side plate frames 53 can be conveyed into the smoking hood 1 above. The cushion blocks 51 are made of rubber materials and have the effect of buffering and shock absorption. The support plates 52 are welded to both sides of the outer wall of the printing machine main body 2. The cushion blocks 51 can be placed downward on the top ends of the support plates 52. In this way, the smoking hood 1 can be buckled on the top of the printing machine main body 2. At the same time, the two side plate frames 53 on both sides will stand vertically on both sides of the combustion chamber of the printing machine main body 2. Both the first filter screen 56 and the second filter screen 54 are made of stainless - steel metal grid plates with a certain size of holes. Through the first filter screen 56 and the second filter screen 54, the smoke can be normally sucked in, while the solid impurities are isolated outside to reduce blockage.
