Detailed Description
The following describes embodiments of the present invention in detail with reference to the drawings, which are implemented on the premise of the technical solution of the present invention, and give detailed implementation manners and specific working procedures, but the scope of the present invention is not limited to the following embodiments.
The smoke trapping and purifying system for the large casting cutting casting head is suitable for the working condition that a plurality of cutting stations are randomly distributed in a cutting operation area, and in a general condition, a group of trapping and purifying units are correspondingly arranged on each group of cutting stations with the same transverse position. The specific structure of the first group of trapping and purifying units on the left side in FIG. 1 is described as an example.
As shown in FIGS. 1-4, the single capture and purification unit is mainly composed of a flue gas capture part and a ventilation and dust removal part. The smoke trapping part comprises a door-shaped cover body 11 stretching over the cutting operation area, rollers 12 moving longitudinally along the cutting operation area are mounted at the bottom of the door-shaped cover body 11, and the rollers 12 are matched with longitudinal rails 13 mounted at two ends of the cutting operation area to facilitate movement of the door-shaped cover body 11. The two sides of the door-shaped cover body 11 are provided with movable doors 14 (usually rolling doors or telescopic doors), so that when smoke is collected, the rolling doors are closed to prevent the smoke from overflowing. In order to improve the attaching effect of the top attaching jet and the smoke trapping effect, a bracket or a purlin is arranged outside the door-shaped cover body 11, and a smooth plate body is used as the inner surface of the door-shaped cover body 11. The top of the door-shaped cover body 11 is provided with the blowpipe 2 and the air suction pipe 3, the air suction section of the air suction pipe 3 is positioned in the middle of the top surface of the cover body, the first branch pipe and the second branch pipe of the blowpipe 2 are positioned on two sides of the first branch pipe and the second branch pipe, and the blowpipe, the second branch pipe and the third branch pipe are parallel to each other. The airflow blown out from the first branch pipe and the second branch pipe is attached to the top wall of the door-shaped cover body 11 and enters the suction pipe 3, and attached jet flow which is easy to capture high-temperature smoke is formed. The exhaust end of the air suction pipe 3 and the air inlet end of the blowing pipe 2 are both arranged on the end wall of one side of the door-shaped cover body 11 and are respectively a first connector 31 and a second connector 21 of an electromagnetic suction type.
The ventilation and dust removal part is arranged on the outer side of the door-shaped cover body and comprises a moving vehicle 6 (usually a rail vehicle) for placing the ventilator 4 and the dust remover 5. The end part of the inlet pipe of the ventilator 4 is provided with a third interface 41, the outlet pipe of the ventilator 4 is communicated with the inlet of the dust remover 5, the outlet pipe of the ventilator 4 is also communicated with a return air branch pipe 7, and the end part of the return air branch pipe is provided with a fourth interface 71. The third interface 41 and the fourth interface 71 also adopt electromagnetic suction type interfaces.
When the trapping and purifying unit is in the working state, the third port 41 is communicated with the first port 31, and the fourth port 71 is communicated with the second port 21. When the high-temperature flue gas collecting hood works, the fourth interface 71 of the ventilator 4 blows air into the hood, attached jet flow is formed on the inner wall of the top plate of the collecting hood, and the high-temperature flue gas is collected and then is sent to the ventilator 4 through the air suction pipe 3; the smoke discharged from the ventilator 4 is divided into two parts at the outlet, one part of air forms attached jet flow on the inner wall of the top plate of the collecting cover by using an air supply system and an attached jet flow air port, and the other part of air is sent to the dust remover 5 to be purified and then to be emptied. The operation mode greatly improves the trapping efficiency of the trapping cover, improves the cutting operation environment, reduces the total emission amount of particulate matters, and reduces the operation energy consumption of the flue gas trapping system. For areas needing heating, the external air discharge rate of a workshop can be greatly reduced, the heating energy consumption of ventilation is reduced, the heating load is reduced, and the heating energy consumption is saved. Furthermore, because each trapping and purifying unit is independently arranged, the flexibility of the trapping cover is improved, the number of the trapping and purifying units can be selected according to the running condition of the actual cutting station, unnecessary energy consumption is reduced, and the working efficiency of the process is improved.
Normally, a position sensor is further installed outside the door-shaped cover 11, and when the door-shaped cover 11 reaches a preset position (i.e., the third interface 41 corresponds to the first interface 31, and the fourth interface 71 corresponds to the second interface 21), the position sensor sends a signal to the control center, and then the control center sends a signal to magnetically connect the third interface 41 and the first interface 31, and the fourth interface 71 and the second interface 21, respectively. Then, the ventilator 4 and the dust remover 5 are started, and the smoke dust can be collected and purified.
Further, different sets of door-shaped covers 11 are provided in accordance with different sizes. Because the flue gas trapping part and the ventilation dust removal part can be conveniently separated (after the dust removal purification is finished, the control center sends a signal to separate the third interface 41 from the first interface 31 and separate the fourth interface 71 from the second interface 21), the door-shaped cover body 11 can be telescopically stored, the whole floor area is reduced, and the purpose of providing sufficient working space for other processes is achieved.
It should be noted that in the description of the present invention, terms of orientation or positional relationship such as "front", "rear", "left", "right", "vertical", "horizontal", "inner", "outer", etc., are based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
