Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a waste gas treatment device for casting automotive parts processing. Background Technology

[0002] The manufacturing of automotive parts requires casting processes to achieve complex structural forming, improve material performance, and reduce production costs. Casting processes generate a large amount of waste gas, which will pollute the environment if directly emitted. Therefore, appropriate devices are needed to treat the waste gas in a harmless manner.

[0003] Most current waste gas treatment devices initially filter harmful substances in waste gas through filters. After a period of use, the filtration efficiency of the filter element decreases, and the filter element needs to be replaced regularly. However, when replacing the filter element, the casting process needs to be suspended in most devices, and processing can only resume after the replacement, which results in a lot of downtime and affects the continuous operation of casting.

[0004] Therefore, in response to the situation where existing exhaust gas treatment devices require shutdown for replacement work, an exhaust gas treatment device for automotive parts processing and casting can be designed. Through the dual-channel alternating exhaust method, there is no need to stop the machine to replace the filter element. The operation is simple and convenient, ensuring that processing operations can be carried out continuously, improving the casting efficiency of automotive parts, increasing output, and thus effectively enhancing the practical value of the device.

[0024] Please see Figure 1 and Figure 3 In this embodiment, two sets of support rods 101 are symmetrically arranged at the top of the processing table 1. A fixing ring block 102 is provided at the top of the support rod 101. The fixing ring block 102 is located on the outer side of the bottom end of the main exhaust pipe 3. A control panel 103 is provided on the outer side of the fixing ring block 102. The control panel 103 is electrically connected to the vacuum pump 4. The fixing ring block 102 is supported by the support rods 101. The main exhaust pipe 3 is fixedly supported by the fixing ring block 102, ensuring that the main exhaust pipe 3 and the vacuum hopper 2 are placed stably. The control panel 103 sends an operation command to the vacuum pump 4, thereby ensuring that the vacuum pump 4 runs continuously during the processing and casting process to perform waste gas extraction.

[0025] A first controller 601 is provided on the outside of the first butterfly valve 6, and a second controller 701 is provided on the outside of the second butterfly valve 7.

A retaining strip 904 is provided between the two sets of limiting rings 903. The retaining strip 904 engages with the slot 902. The housing 901 protects the filter element body 9. When installing the filter element body 9, the limiting rings 903 are used to define the installation position of the housing 901. The housing 901 is placed between the limiting rings 903, so that the retaining strip 904 engages with the slot 902. 4. The embedded slot 902 ensures that the filter element body 9 is stably placed in the mounting slot 8; the outer side of the main exhaust pipe 3 and the auxiliary exhaust pipe 5 is provided with a first sealing groove 1001, which is symmetrically opened on both sides of the mounting slot 8. The inner ends of the arc-shaped sealing plate 10 are provided with arc-shaped sealing strips 1002, which are fitted and connected with the first sealing groove 1001. When the arc-shaped sealing plate 10 is closed, it blocks the mounting slot 8, so that the arc-shaped sealing strip 1002 is embedded in the first sealing groove 1001, and the sealing effect of the arc-shaped sealing plate 10 is ensured by the arc-shaped sealing strip 1002.

[0027] A first mounting plate 1003 is provided at both ends of the outer side of the arc-shaped sealing plate 10, and a second mounting plate 1004 is provided on the outer side of the main exhaust pipe 3 and the auxiliary exhaust pipe 5.

Bolts 1008 are provided on the inner side of the mounting holes 1007. Bolt 1008 is threadedly connected to mounting hole 1007. A locking nut 1009 is provided at the bottom end of bolt 1008. The locking nut 1009 is threadedly connected to bolt 1008. When the arc-shaped sealing plate 10 is closed, the first mounting plate 1003 is attached to the second mounting plate 1004. The second sealing strip 1006 is embedded in the second sealing groove 1005. The second sealing strip 1006 is used to further ensure the sealing effect of arc-shaped sealing plate 10. Bolt 1008 is screwed into mounting hole 1007, and then the locking nut 1009 is screwed into the other end of bolt 1008, thereby locking arc-shaped sealing plate 10 onto the outside of mounting groove 8.

[0028] During processing, the fixed ring block 102 is supported by the support rod 101, and the position of the main exhaust pipe 3 and the air extraction bucket 2 is fixed by the fixed ring block 102. The parts are processed and cast by the processing table 1. The air extraction pump 4 is controlled by the control panel 103. The air extraction pump 4 is started to control the air extraction bucket 2 to extract the waste gas generated during processing. The waste gas flows through the filter element body 9 in the main exhaust pipe 3 for filtration and is then discharged.

[0029] When replacing the filter element body 9 in the main exhaust pipe 3, the control panel 103 sends an operation command to the first controller 601 and the second controller 701. The first controller 601 controls the first butterfly valve 6 to block the main exhaust pipe 3, and the second controller 701 controls the second butterfly valve 7 to open the auxiliary exhaust pipe 5, guiding the exhaust gas into the auxiliary exhaust pipe 5. The exhaust gas flows through the filter element body 9 in the auxiliary exhaust pipe 5 for filtration and is then discharged.

[0030] Subsequently, the exhaust gas treatment operation continued. The locking nut 1009 on the main exhaust pipe 3 was unscrewed in sequence, and the bolt 1008 was unscrewed from the mounting hole 1007 in sequence. The arc-shaped sealing plate 10 was removed, and the old filter element body 9 in the mounting groove 8 was taken out.

[0031] When installing the new filter element body 9, place the new filter element body 9 into the mounting groove 8 of the main exhaust pipe 3, so that the slot 902 is embedded in the slot strip 904, place the outer shell 901 between the limiting rings 903, close the arc-shaped sealing plate 10, so that the first mounting plate 1003 is attached to one side of the second mounting plate 1004, embed the arc-shaped sealing strip 1002 into the first sealing groove 1001, and at the same time, embed the second sealing strip 1006 into the second sealing groove 1005, and then screw the bolts 1008 into the mounting holes 1007 in sequence, and screw the locking nut 1009 into the other end of the bolts 1008, so that the arc-shaped sealing plate 10 tightly seals the mounting groove 8, and the filter element body 9 replacement operation is completed. The operation steps are the same when replacing the filter element body 9 in the auxiliary exhaust pipe 5.

[0032] Through the above steps, the parts are processed and cast using a processing table 1. The vacuum pump 4 is started to control the main exhaust pipe 3 to extract the waste gas generated during processing. The waste gas is then pumped through the vacuum hopper 2 to the main exhaust pipe 3 for discharge. The main exhaust pipe 3 is flexibly blocked by the first butterfly valve 6, and the auxiliary exhaust pipe 5 is flexibly blocked by the second butterfly valve 7. The first butterfly valve 6 and the second butterfly valve 7 are opened and closed alternately to guide the waste gas to the main exhaust pipe 3 or the auxiliary exhaust pipe 5 for discharge. The installation position of the filter element body 9 is clearly defined by the installation groove 8, and the installation groove 8 is flexibly blocked by the arc-shaped sealing plate 10, thus facilitating the replacement of the filter element body 9. During the exhaust process, the waste gas flows through the filter element body 9 and is filtered, thus achieving filter element replacement without stopping the machine. The operation is simple and convenient, ensuring that the processing operation can be carried out continuously, improving the casting efficiency of automotive parts and increasing production.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments.
