Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning equipment for wide-channel plate heat exchangers, and particularly relates to a fixing device for a high-pressure water jet cleaning gun head. Background Art

[0002] The wide-channel plate heat exchanger (referred to as the wide plate) is a commonly used heat exchange device in industrial enterprises. In the evaporation and decomposition process of alumina production enterprises, the wide plate is mainly used to exchange heat between materials and water, so as to achieve the effect of gradient cooling of the materials, and the material temperature can be controlled within the process requirements by adjusting the water volume.

[0003] In recent years, with the change of working conditions in alumina enterprises, mainly after using imported bauxite, organic substances in the system are continuously precipitated, affecting the whole production. The wide plate is also seriously affected during use, and the heat exchange efficiency gradually becomes worse. In the past, maintenance was carried out by means of alkaline washing in the material phase and acid washing in the water phase, but the effect was not good. After repeated inspections, the main problem is still the enrichment of organic substances in the material-phase flow channels, resulting in the narrowing of the flow channels and the deterioration of the heat exchange efficiency. Since organic substances are insoluble in acids and alkalis, in order to protect the flow channels from being damaged, the existing means can only remove organic substances by means of water jet cleaning. After testing, the heat exchange effect becomes better.

[0004] However, in the prior art, during the high-pressure water jet cleaning process, the following problems still exist:

[0005] 1. The hydraulic pressure of the high-pressure water jet cleaning equipment is relatively high, about 800 bar. The specific operation needs to be completed manually, and the large impact force of the gun head after it is turned on poses a great safety hazard to the operators.

[0006] 2. The distance between the material-phase flow channels of the wide plate is 12 mm, and the diameter of the existing standard water jet cleaning gun head is 17 mm. For the brand-new wide-plate flow channels, the gun head cannot enter the interior of the flow channels, and the strong water pressure after the water outlet is more likely to cause harm to the operators or the surrounding environment.

[0007] 3. The distance between the material phases of the wide plate is small, and the width of the flow channel is about 1 m. Even if the operator holds the gun head firmly, it cannot be moved back and forth, resulting in incomplete cleaning. If the gun stock is moved, there are also great safety hazards. Content of the Utility Model

[0008] The utility model provides a fixing device for a high-pressure water jet cleaning gun head for the above problems.

[0009] To achieve the above purpose, the utility model adopts the following technical solutions:

[0010] A fixing device for a high-pressure water jet cleaning gun head, including a sleeve. The upper and lower ends of the front part of the sleeve are connected to angle steel, and the angle steel is connected to a wide plate door frame through bolts. On the left and right sides of the rear part of the sleeve, hinge shafts are fixedly connected, and a U-shaped limiting ring is jointly hinged on the two hinge shafts.

[0011] Furthermore, a clamping nut is threadedly connected to the hinge shaft for fixing the rotation angle of the U-shaped limiting ring after the U-shaped limiting ring is adjusted in place.

[0012] Still further, connecting shafts are fixedly arranged at the upper and lower ends of the front part of the sleeve, and the connecting shafts are rotatably connected to the angle steel.

[0013] Even further, a limiting nut is threadedly connected to the connecting shaft, and by adjusting the position of the limiting nut, the height of the sleeve can be adjusted.

[0014] Even further, a sliding groove is arranged on the angle steel, and the connecting shaft is slidably arranged in the sliding groove and can rotate in the sliding groove.

[0015] Compared with the prior art, the present utility model has the following advantages:

[0016] The structure of the present utility model is simple, the manufacturing cost is low, and the disassembly is convenient. The whole is fixed by bolts and nuts;

[0017] The present utility model is easy to operate. The up and down movement of the sleeve can be realized by adjusting the limiting nut, and the left and right movement can be realized through the sliding groove, which is convenient for adjusting the position of the gun head during the cleaning process;

[0018] The present utility model has high safety. By combining the sleeve with the U-shaped limiting ring, the fixation of the gun head can be realized, avoiding direct manual holding of the high-pressure water jet cleaning gun head and reducing the occurrence of injury accidents caused by human factors.

[0023] Such as Figure 1 And Figure 2As shown in the figure, a fixing device for a high-pressure water jet cleaning gun head includes a sleeve 1. At the upper and lower ends of the front part of the sleeve 1, connecting shafts 7 are fixedly arranged. A limiting nut 8 is threadedly connected to the connecting shaft 7. By adjusting the position of the limiting nut 8, the height of the sleeve 1 can be adjusted. A sliding groove 9 is provided on the angle steel 2. The connecting shaft 7 is slidably arranged in the sliding groove 9 and can rotate in the sliding groove 9. The angle steel 2 is connected to the wide plate door frame 3 by bolts. At the left and right sides of the rear part of the sleeve 1, hinge shafts 4 are fixedly connected. A U-shaped limiting ring 5 is jointly hinged on the two hinge shafts 4. A clamping nut 6 is threadedly connected to the hinge shaft 4 for fixing the rotation angle of the U-shaped limiting ring 5 after the U-shaped limiting ring 5 is adjusted in place.

[0024] During specific use, the barrel part of the high-pressure water jet cleaning gun head is inserted into the sleeve 1. Then, the U-shaped limiting ring 5 is lifted to limit the grip part, preventing the high-pressure water jet cleaning gun head from slipping off under high pressure. Then, the clamping nut 6 is tightened to fix the angle of the U-shaped limiting ring 5. During the cleaning process, the height of the high-pressure water jet cleaning gun head can also be adjusted by rotating the limiting nut 8, and the position of the high-pressure water jet cleaning gun head can be adjusted by the movement of the connecting shaft 7 in the sliding groove 9.
