Description

Technical Field

[0001] This utility model relates to the field of filter manufacturing technology, and in particular to a welding auxiliary device for perlite filter tanks. Background Technology

[0002] Perlite filters are a new type of water treatment equipment that uses perlite powder as the filter medium. Perlite filters can remove solid suspended matter as small as 1 micron from water. The removal rate of microorganisms such as E. coli and algae can reach more than 99.5%. They also have a good removal effect on viruses, Cryptosporidium, Giardia lamblia, etc. Perlite filters do not require backwashing, saving a lot of water and electricity. Their filter media can be activated and reused, reducing the use of chemical substances, saving water and reducing wastewater discharge.

[0003] The exterior of the perlite filter is a metal tank, which is generally produced by bending and welding steel plates. During the welding process, in order to fit the two ends of the steel plate together, an auxiliary device is needed to clamp the ends. However, after the steel plate is bent, two situations may occur: insufficient bending will result in excessive gaps, and excessive bending will result in overlapping ends. The existing auxiliary clamping device cannot freely switch between applying pressure and internal support according to different production needs, which makes the welding operation very inconvenient. Utility Model Content

[0004] This utility model addresses the deficiencies in the existing technology by providing a welding auxiliary device for perlite filter tanks.

[0005] This utility model is achieved through the following technical solution:

[0006] A welding auxiliary device for a perlite filter tank includes a base, a guide support, a side pressure mechanism, and a top pressure mechanism. The guide support is fixedly mounted on the upper surface of the base. The side pressure mechanism is fixedly mounted on the top of both sides of the base. The top pressure mechanism is engaged inside both ends of the guide support. The top pressure mechanism includes a slide rod, a connecting plate, and a pressure applying device. The connecting plate is fixedly mounted on both sides of the slide rod. The pressure applying device is engaged inside the connecting plate. The pressure applying device includes a mounting base, a screw, a retaining seat, a limiting nut, a second hydraulic cylinder, and a top block. The screw is fixedly mounted on both ends of the mounting base. The retaining seat is sleeved on the outside of the screw. The limiting nut is threadedly connected to the screw. The second hydraulic cylinder is fixedly mounted on the top of the mounting base. The top block is fixed to the output end of the second hydraulic cylinder.

[0007] In a preferred embodiment of the present invention, the side pressure mechanism includes a cylinder seat, a sliding seat, a first cylinder and a pressure block. The sliding seat is engaged inside the cylinder seat, the first cylinder is installed on the back of the sliding seat, and the pressure block is fixedly disposed on the telescopic end of the first cylinder.

[0008] The side pressure mechanism applies pressure from the side of the rolled plate. When the filter tank is not rolled up properly, the side pressure can help the end of the plate to be pressed and contacted, which facilitates welding.

[0009] In a preferred embodiment of the present invention, the sliding seat and the card seat are provided with card slots on both sides, the cylinder seat is provided with a vertical sliding groove that mates with the sliding seat, the connecting plate is provided with an inclined slot that mates with the card seat, and the back of the sliding seat and the card seat are connected with locking screws by threads.

[0010] The sliding seat moves within the groove on the surface of the cylinder to adjust the installation height of the first cylinder, thereby adjusting the pressure position of the pressure block. The sliding seat is tensioned and fixed within the groove of the cylinder seat by the locking screw. Similarly, the clamp is fixed within the slot on the surface of the connecting plate so that the second cylinder can control the top block to apply pressure to the top of the welding area from top to bottom, reducing the gap and facilitating the welding work.

[0011] In a preferred embodiment of the present invention, a V-shaped pressure groove is provided on the outer side of the pressure block and the top of the guide support seat, an adjusting slide plate is fixedly provided at the bottom of the slide rod, and a slide groove is provided at the top of the guide support seat to cooperate with the slide rod and its bottom adjusting slide plate;

[0012] The adjustable slide plate facilitates the sliding of the slide rod within the guide support seat while also serving as a limit to improve stability. The pressure block and the V-shaped pressure groove on the top of the guide support seat ensure the pressure application effect.

[0013] In a preferred embodiment of this utility model, a guide strip is provided on the inner side of the card holder, a guide groove that cooperates with the screw is opened on the surface of the screw, and a limiting nut is provided on both sides of the card holder;

[0014] The guide strip inside the card holder is locked in the guide groove on the screw surface to ensure that the card holder will not rotate freely on the screw surface, and is clamped and fixed by the limit nuts on both sides.

[0015] The beneficial effects of this utility model are:

[0016] This perlite filter tank welding auxiliary device can adjust the auxiliary pressure effect according to the degree of steel plate bending. When the steel plate is not bent in place, resulting in excessive gaps, the bent steel plate is adjusted by lateral support and top pressure, so that its ends can effectively contact each other and the gaps are significantly reduced. When excessive bending causes the two ends of the steel plate to overlap, the pressure device can change the installation angle to provide support from the inside, lift the two ends of the steel plate, so that the two ends fit together, which facilitates welding work and meets the needs of different scenarios.

[0024] like Figure 1-5 The illustrated perlite filter tank welding auxiliary device includes a base 1, a guide support 2, a side pressure mechanism 3, and a top pressure mechanism 4. The guide support 2 is fixedly installed on the upper surface of the base 1. The side pressure mechanism 3 is fixedly installed on the top of both sides of the base 1. The top pressure mechanism 4 is engaged inside both ends of the guide support 2. The top pressure mechanism 4 includes a slide rod 41, a connecting plate 42, and a pressure applying device 43. The connecting plate 42 is fixedly installed on both sides of the slide rod 41. The pressure applying device 43 is engaged inside the connecting plate 42. The pressure applying device 43 includes a mounting base 431, a screw 432, a retaining seat 433, a limiting nut 434, a second hydraulic cylinder 435, and a top block 436. The screw 432 is fixedly installed on both ends of the mounting base 431. The retaining seat 433 is sleeved on the outside of the screw 432. The limiting nut 434 is threadedly connected to the screw 432. The second hydraulic cylinder 435 is fixedly installed on the top of the mounting base 431. The top block 436 is fixed to the output end of the second hydraulic cylinder 435.

[0025] Specifically, the side pressure mechanism 3 includes a cylinder seat 31, a sliding seat 32, a first cylinder 33, and a pressure block 34. The sliding seat 32 is locked inside the cylinder seat 31, the first cylinder 33 is installed on the back of the sliding seat 32, and the pressure block 34 is fixedly installed on the telescopic end of the first cylinder 33. The sliding seat 32 and the card holder 433 have slots on both sides. The cylinder seat 31 has a vertical groove that mates with the sliding seat 32. The connecting plate 42 has an inclined slot that mates with the card holder 433. The back of the sliding seat 32 and the card holder 433 are connected by a locking screw. The outer side of the pressure block 34 and the top of the guide support 2 have a V-shaped pressure groove. The bottom of the slide rod 41 is fixedly provided with an adjusting slide plate. The top of the guide support 2 has a groove that mates with the slide rod 41 and its bottom adjusting slide plate. The inner side of the card holder 433 is provided with a guide strip. The surface of the screw rod 432 has a guide groove that mates with it. The limit nut 434 is provided on both sides of the card holder 433.

[0026] In this embodiment, the first step is to determine the state of the steel plate rolling of the filter tank. If the rolling is incomplete, resulting in excessive separation at both ends, the rolled steel plate is first placed on top of the guide support 2 with the opening facing upwards. At this point, the locking screw on the back of the sliding seat 32 is loosened, and the pressure block 34 is adjusted to be located outside the sides of the tank. Then, the locking screw is tightened to lock the height of the sliding seat 32. Subsequently, the bottom adjusting slide plate of the slide rod 41 is inserted into the sliding grooves at both ends of the guide support 2, and the retainer 433 is fitted onto the outside of the screw rod 432. Then, the card holder 433 is inserted into the slot on the surface of the connecting plate 42. The limiting nuts 434 are tightened on both sides of the card holder 433. After adjusting the height of the card holder 433, the locking screw on its back is tightened to effectively fix the pressure device 43. Then, the first hydraulic cylinder 33 and the second hydraulic cylinder 435 are extended. The first hydraulic cylinder 33 controls the pressure block 34 to apply pressure from both sides, and the second hydraulic cylinder 435 controls the top block 436 to apply pressure from the top, thereby controlling the shrinkage of the top gap of the bent plate until the two ends contact each other, which facilitates the welding work.

[0027] Furthermore, when the steel plate of the production tank is excessively bent, causing the two ends to overlap, the pressure block 34 at the telescopic end of the first hydraulic cylinder 33 mainly serves as a limiting effect. The pressure block 34 is set to a higher position without applying auxiliary pressure. At this time, the pressure device 43 needs to be inserted into the inside of the steel coil and installed in reverse so that the top block 436 is tilted upward. Then, the card seat 433 is fixed in the connecting plate 42 at a suitable height. Then, the second hydraulic cylinder 435 is pushed out, which can push the top block 436 from the inside to the outside, thereby opening up the overlapping position and connecting the ends to facilitate welding. At this time, the pressure block 34 serves as a limiting effect, applying downward pressure from the outside to the top of the steel coil, effectively preventing the rolled steel plate from moving upward due to internal pressure.
