Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a bag filter processing welding device. Background Art

[0002] The bag filter is a dry dust filter. It is suitable for capturing fine, dry, non-fibrous dust. It is mainly composed of a box, a filter bag, an injection system and a suspension system. The box is composed of an upper shell and an ash hopper. Generally, the upper shell and the ash hopper are fixedly connected by welding to form a whole. During the welding process, the upper shell needs to be placed on the ash hopper first, and the contact surface between the two is aligned. Then, auxiliary welding is performed by welding rods. During electric welding, the welding clamp needs to be lifted manually. After completing the welding work on one side, continue welding on the other side until a circle is completed, so that the welding between the upper shell and the ash hopper can be achieved.

[0003] However, although the above-mentioned welding method can eventually achieve the connection between the upper shell and the ash hopper, the bag dust collector is generally large in size. Manual workers need to continuously lift the welding clamp on one side and constantly switch sides for welding on the other side, which will soon make their arms sore, making it easy to make welding errors, resulting in irregular welding positions, reducing the appearance of the appearance, and, as the degree of fatigue increases, the welding efficiency also declines.

[0004] Therefore, it is necessary to provide a bag filter processing welding device to solve the above technical problems. Summary of the invention

[0043] In this embodiment

[0044] A welding machine box is fixed on the welding machine mounting seat 39, and the welding machine box is used in conjunction with the welding clamp 38, and the two are connected by wires. In the initial state, a transport vehicle is provided on the side of the first supporting side plate 22 away from the supporting platform 1, and the transport vehicle is used to transport the welded dust collector;

[0045] When welding is required for the bag filter, the dust hopper is first placed on the welding table 65, and then the height of the four first positioning pieces 15 is adjusted according to the top position of the dust hopper. During the adjustment, one of the first vertical screws 12 is first rotated to drive the corresponding first lifting plate 13 to rise, and then the corresponding first positioning piece 15 can be driven to rise until it rises to the specified height, and then the other first positioning pieces 15 are adjusted in the same way, so that the first positioning piece 15 is closer to the top position of the dust hopper, which can ensure the stability of the welding process;

[0046] Then, the second drive motor is started in the positive direction, and its output shaft drives the first bidirectional lead screw 5 to rotate, so that the two corresponding linkage plates 10 are close to each other. When the first ball on one of the first positioning pieces 15 contacts the ash discharge hopper, the ash discharge hopper will be pushed until the first ball on the other first positioning piece 15 also contacts the ash discharge hopper. At this time, the ash discharge hopper is in a horizontally centered position. Then, the third drive motor is started, and its output shaft drives the second bidirectional lead screw 8, so that the two corresponding linkage plates 10 are close to each other. When the corresponding first positioning piece 15 contacts the ash discharge hopper, the ash discharge hopper will be pushed until the other first positioning piece 15 also contacts the ash discharge hopper. At this time, the ash discharge hopper is in a longitudinally centered position.

[0047] Then, the fifth drive motor is started in the forward direction first, and its output shaft drives the third rotating shaft 24 to rotate, and then can drive the rotating frame 25 and the cross connecting plate 18 to rotate. After the rotating frame 25 rotates 180°, there is no obstruction of foreign objects on the upper side of the welding table 65. Then, the sixth drive motor is started in the forward direction first, and its output shaft drives the second vertical lead screw 26 to rotate. At this time, through the threaded cooperation between it and the second lifting plate 27, the second lifting plate 27 can be driven to rise, and then can drive the cross connecting plate 18 and the first telescopic cylinder 20 to rise. After lifting the first telescopic cylinder 20 to the highest height, the sixth drive motor is turned off. Subsequently, the upper shell is placed above the ash discharge hopper. At this time, the upper shell and the ash discharge hopper are not placed in place. Next, the fifth drive motor is started in the reverse direction, and its output shaft drives the rotating frame 25 to rotate. After it rotates 180°, , the cross connecting plate 18 brings the first telescopic cylinder 20 back to the original position, and then the sixth drive motor is started in the reverse direction. The cross connecting plate 18 brings the first telescopic cylinder 20 down until the cross connecting plate 18 is about to touch the top of the upper shell, and then the sixth drive motor is turned off, and then the two first telescopic cylinders 20 in the horizontal direction are started first, and the corresponding two second positioning pieces 21 are close to each other, and finally the upper shell is fixed in the horizontal horizontal center position, and then the output shafts of the other two first telescopic cylinders 20 are started to extend, so that the corresponding two second positioning pieces 21 are close to each other. When one of the second positioning pieces 21 touches the upper shell, it will push the upper shell until the other second positioning piece 21 also touches the upper shell. At this time, the upper shell is in the longitudinal horizontal center position, so that the positioning between the ash hopper and the upper shell is completed;

[0048] Then, the height of the welding clamp 38 is adjusted according to the height of the connection between the ash discharge hopper and the upper shell body. When adjusting, the third vertical screw 40 is directly rotated, and the third lifting plate 41 will rise with the linkage table 43, and then the welding clamp 38 can be raised until it moves to the height corresponding to the connection between the ash discharge hopper and the upper shell body. Then, the first fastening bolt and the second fastening bolt are screwed to allow the slider 32 and the transverse slide seat 35 to slide, and then the welding rod is clamped on the welding clamp 38, and the grip 37 is held to move. When the welding rod contacts the connection between the ash discharge hopper and the upper shell body, electric welding can be carried out. During the electric welding process, the movement of the transverse slide seat 35 can be used to adapt to the gradual shortening of the welding rod. At the same time, the connection of the entire side between the ash discharge hopper and the upper shell body can be welded by sliding the slider 32 on the slide rail 31, and the operation is relatively free and convenient.

[0049] After the ash discharge hopper and one side of the upper shell are welded, the electric welding clamp 38 is first returned to the starting position, and then the first drive motor and the fourth drive motor are started forward, so that the outer concave frame 3 with the welding table 65 and the cross connecting plate 18 start to rotate. After rotating 90°, the above two motors are turned off. At this time, the ash discharge hopper and the upper shell are switched, and then the electric welding clamp 38 is continued to perform welding work, and this reciprocating operation is repeated until the welding work on the four sides of the ash discharge hopper and the upper shell is completed.

[0050] When welding is completed, the overall structure of the bag dust collector shell is formed, and then the sixth drive motor is directly started in the forward direction, and the second lifting plate 27 begins to rise, and the welded dust collector shell can be raised. When it is lifted to a position higher than the first positioning plate 15, the fifth drive motor can be started to rotate the clamped dust collector shell and rotate it to the top of the transport vehicle. Then, the sixth drive motor is started in the reverse direction to place it on the transport vehicle, and the output shaft of the first telescopic cylinder 20 is started to retract and release it. Then, the next ash hopper to be welded is placed on the welding table 65, and the next group of welding work can be carried out according to the same operation as above.

[0051] Compared with the related art, the bag filter processing and welding device provided by the present invention has the following beneficial effects:

[0052] 1. By means of the first positioning piece 15 and the second positioning piece 21 arranged in the transverse and longitudinal directions, the ash hopper and the upper shell can be clamped in a centering manner, so that the welding points of the two can be accurately aligned and the welding accuracy can be improved. Then, the two can be welded. In the welding process, the electric welding clamp 38 can be fixed by the handle 37 and connected to the transverse slide 35 without manual continuous lifting. The welding work can be achieved by controlling the direction of the electric welding clamp 38, which reduces the manual burden and realizes a continuous and stable welding height without deviation. This not only further improves the welding accuracy, but also ensures the flatness of the weld and improves the aesthetics of the dust collector after welding.

[0054] 3. By utilizing the clamping effect of the second positioning piece 21 on the upper shell, after welding is completed, the welded dust collector can be directly lifted from the welding table 65 by controlling the fifth drive motor and the sixth drive motor, so as to facilitate the next batch of welding work. In addition, the four first positioning pieces 15 and the four second positioning pieces 21 can be clamped according to the actual size of the ash hopper and the upper shell, and have high applicability.

A longitudinal pipe 49 is fixed to the other end of the first corrugated pipe 52, and a plurality of air inlet scoops 50 are fixed to the longitudinal pipe 49. In the use state, the plurality of air inlet scoops 50 are located below the electric welding clamp 38, and the air inlet scoops 50 are relatively close to the welding part, so that the unpleasant gas can be absorbed to the greatest extent. A U-shaped frame 45 is fixed on one side of the carrier plate 44 close to the second supporting side plate 29, and a transverse lead screw 46 is rotatably installed therein. The transverse lead screw 46 A push piece 47 is installed on the upper thread, and two positioning rods are fixed in the U-shaped frame 45. The two positioning rods penetrate the push piece 47 and are slidably connected thereto, and a support rod 48 is fixed on the side of the push piece 47 close to the carrier plate 44. The end of the support rod 48 away from the push piece 47 penetrates the carrier plate 44 and is fixedly connected to the longitudinal tube 49. The support rod 48 is slidably connected to the carrier plate 44. Two filter boxes 55 are fixed on the second supporting side plate 29. One side of the two filter boxes 55 is set as an opening. A plurality of activated carbon honeycomb adsorption plates 56 are arranged in the two filter boxes 55. The opening sides of the two filter boxes 55 are fixed with inspection door panels 57 by bolts. The multiple activated carbon honeycomb adsorption plates 56 in the two filter boxes 55 The adsorption plates 56 are fixedly connected to the corresponding inspection door panels 57, so that it is convenient to remove and replace the activated carbon honeycomb adsorption plates 56. An air inlet pipe 58 is fixed on the side of the two filter boxes 55 away from the second supporting side plate 29. One end of the second corrugated pipe 53 is fixed to the air outlet end of the exhaust fan 51, and a connecting cross pipe 54 is fixed to the other end of the second corrugated pipe 53. The end of the connecting cross pipe 54 is in contact with one of the air inlet pipes 58. An exhaust pipe 63 is fixed to the second supporting side plate 29. An air guide pipe 64 is fixed on the side of the two filter boxes 55 close to the second supporting side plate 29.

Both air guide pipes 64 are provided with air Valve, and two connecting rods 59 are fixed on the connecting cross pipe 54, and sealing plates 60 are fixed at the ends of the two connecting rods 59. The two sealing plates 60 are respectively adapted to the two air inlet pipes 58, and one of the sealing plates 60 is in contact with the corresponding air inlet pipe 58. During use, one air valve is opened and the other air valve is closed. The opened air valve is discharging the filtered gas, and the activated carbon honeycomb adsorption plate 56 can be replaced in the filter box 55 corresponding to the closed air valve. After the activated carbon honeycomb adsorption plate 56 is replaced, the sealing of the air inlet pipe 58 by the sealing plate 60 and the closing of the air valve prevents external gas from entering the filter box 55 and affecting the activated carbon honeycomb adsorption plate 56.

[0059] In the above method, in order to facilitate the adjustment of the connecting cross tube 54 to fit the corresponding air inlet pipe 58, a rodless cylinder 61 is fixed on one side of the loading plate 44 close to the second supporting side plate 29, and a second telescopic cylinder 62 is fixed on the movable block of the rodless cylinder 61, and its output shaft is fixedly connected to the connecting cross tube 54.

[0061] In the initial state, the output shaft of the second telescopic cylinder 62 is in an extended state, and the air valve on the air guide pipe 64 corresponding to the connecting cross pipe 54 is in an open state;

[0062] During the welding process, a large amount of unpleasant and harmful gases to the human body are generated. In order to purify these gases and reduce the damage to the human body, the exhaust fan 51 can be started while welding. At this time, negative pressure is generated around the air inlet 50, and most of the unpleasant and harmful gases generated during welding are absorbed. These gases enter the filter box 55 through the first bellows 52, the second bellows 53 and the connecting cross pipe 54, and pass through a plurality of activated carbon honeycomb adsorption plates 56 in sequence, so that the unpleasant elements therein can be adsorbed. Finally, the filtered gas is directly discharged through the exhaust pipe 63;

[0063] In the subsequent use process, when the activated carbon honeycomb adsorption plate 56 in use reaches the end of its adsorption life and needs to be replaced, in order to ensure the continuity of the welding process and prevent the welding from being interrupted, the output shaft of the second telescopic cylinder 62 can be immediately started to retract during the side switching of the ash hopper and the upper shell, so as to separate the connecting cross pipe 54 from the air inlet pipe 58 in contact, and then the rodless cylinder 61 is started, and the movable block thereon brings the second telescopic cylinder 62 down, and finally brings the connecting cross pipe 54 to correspond to the air inlet pipe 58 on the other filter box 55, and then the output shaft of the second telescopic cylinder 62 is started to extend, so that the two are in contact, and at the same time, the other air inlet pipe 58 is also covered by the corresponding sealing plate 60, and then the side switching work is completed, and the corresponding air valve can be opened and the exhaust fan 51 can be started to perform gas purification work;

[0064] On the other side, the inspection door panel 57 corresponding to the used activated carbon honeycomb adsorption plate 56 is removed, and the activated carbon honeycomb adsorption plate 56 can be taken out from the filter box 55, and then replaced;

[0065] And in subsequent use, when operating the ash hoppers and upper shells of different sizes, if the air inlet hopper 50 is far away from the welding position, the transverse screw 46 can be rotated, and the push piece 47 can move laterally with the supporting rod 48, and then the longitudinal tube 49 and the air inlet hopper 50 can be moved laterally under the telescopic performance of the first bellows 52, until the air inlet hopper 50 is moved to a position close to the welding position, the gas purification work can be carried out, and the adaptability is strong.
