Description

Technical Field

[0001] This utility model relates to the field of tungsten-molybdenum hydrometallurgical technology, specifically to a clogging-proof tungsten-molybdenum solution conveying device. Background Technology

[0002] In the tungsten and molybdenum smelting process, the tungsten and molybdenum metal liquid that has been boiled at high temperature needs to be transported by pipeline. During the transportation process, the pipeline is prone to swaying. Most of the existing fixing methods use a single fixing ring for fixation, which is relatively simple in structure and difficult to form a good auxiliary fixing effect according to the actual installation environment. Moreover, during the liquid transportation, the flow rate is prone to instability and poor solution fluidity, which leads to the deposition of some substances in the solution and thus blockage of the pipeline.

[0003] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a clogging-proof tungsten-molybdenum solution conveying device. Utility Model Content

[0004] The purpose of this invention is to provide a clogging-resistant tungsten-molybdenum solution conveying device to solve the problems mentioned in the background art.

A fixing screw is disposed outside the fixing ring, and a U-shaped frame is fixedly connected to the outer circular surface of the fixing screw by a nut. A mounting plate is fixedly connected to the outside of the U-shaped frame by bolts. A snap-fit ​​mechanism is disposed on the outer circular surface of the fixing ring.

[0007] Preferably, the surface of the mounting plate has a through-hole for fixing, and the bolts for fixing the U-shaped frame and the mounting plate can be inserted into the inside of the fixing hole.

[0008] Preferably, the locking mechanism includes a locking slot fixedly connected to the outer circular surface of the fixing ring, a first locking block fixedly connected to the lower end of the fixing screw, and the first locking block can be locked into the inside of the locking slot. The inside of the locking slot can also lock into a second locking block, and a connecting mechanism is provided on the outside of the second locking block.

[0009] Preferably, the connecting mechanism includes a mating screw fixedly connected to the lower surface of the second locking block, the external thread of the mating screw being connected to a nut sleeve, and the lower end of the nut sleeve being fixedly connected to a third locking block.

[0010] Preferably, the inner circular surface of the fixing ring is provided with a shock-absorbing pad, and the shock-absorbing pad is a semi-circular design.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-5 As shown, a clogging-resistant tungsten-molybdenum solution conveying device includes a high-level tank 1 and a control valve 2 located outside the high-level tank 1. A feed pump 3 is installed at one end of the control valve 2, and a flow meter 4 is installed at the other end of the feed pump 3. An extraction tank 5 is installed outside the flow meter 4. A frequency converter 6 is electrically connected between the feed pump 3 and the flow meter 4. A liquid pipeline 7 is connected between the high-level tank 1, control valve 2, feed pump 3, flow meter 4, and extraction tank 5. Several fixing mechanisms 8 are installed outside the liquid pipeline 7. Each fixing mechanism 8 includes two fixing rings 81 located outside the liquid pipeline 7 and fixed together by bolts. A fixing screw 82 is installed outside the fixing rings 81. A U-shaped frame 83 is fixedly connected to the outer surface of the fixing screw 82 by a nut. A mounting plate 84 is fixedly connected to the outer surface of the U-shaped frame 83 by bolts. A snap-fit ​​mechanism 85 is installed on the outer surface of the fixing rings 81. A fixing hole 9 is formed through the surface of the mounting plate 84, and the U-shaped frame is fixed therethrough. The bolts of 83 and mounting plate 84 can be inserted into the fixing hole 9. The design of the fixing hole 9 can adjust the fixing position between U-shaped frame 83 and mounting plate 84 according to the distance of the wall or frame, thereby adjusting the overall length of fixing mechanism 8 and improving practicality. The snap-fit ​​mechanism 85 includes a snap-fit ​​seat 851 fixedly connected to the outer circular surface of fixing ring 81. The lower end of fixing screw 82 is fixedly connected to a first snap-fit ​​block 852, and the first snap-fit ​​block 852 can snap into the inside of snap-fit ​​seat 851. The slot seat 851 can also be fitted with a second card block 853. The second card block 853 is provided with a connecting mechanism 854. The connecting mechanism 854 includes a docking screw 8541 fixedly connected to the lower surface of the second card block 853. The docking screw 8541 is threadedly connected to a nut sleeve 8542. The lower end of the nut sleeve 8542 is fixedly connected to a third card block 8543. The nut sleeve 8542 is a special sleeve design, and a nut is rotatably connected to the upper end of the sleeve.

[0022] By adopting the above technical solution, when installing the tungsten-molybdenum liquid pipeline 7, the external of the liquid pipeline 7 can be fixed by using bolts and fixing rings 81. When reinforcing the pipe body to the external wall or frame, the first locking block 852 can be slid into the slot seat 851, the U-shaped frame 83 can be fixed to the fixing screw 82 by using nuts, and the mounting plate 84 can be fixed to the wall or frame by using bolts. This design can provide auxiliary fixation for the liquid pipeline 7 to prevent swaying during liquid delivery. If it is necessary to connect and fix it to other pipelines, the second locking block 853 can be slid into the slot seat 851, and the third locking block 8543 can be slid into the slot seat 851 of another pipeline. By turning the nut on the nut sleeve 8542 of the connecting screw 8541, the connection and fixation effect can be achieved.

After the flow rate is set by the flow meter 4, if the flow rate drops, the flow meter 4 will give an instruction to adjust the frequency of the frequency converter 6, thereby achieving the purpose of stabilizing the flow rate.

The nut on the outer nut sleeve 8542 of the connecting screw 8541 is tightened for fixation.
