Description
Technical Field
[0001] The utility model relates to the field of chemical industry, in particular to a multi-stage spray washing tower for treating chemical dust. Background Art
[0002] The multi-stage spray scrubber is a device used for gas purification, and its interior adopts a multi-stage purification design. In the initial purification stage, dust particles in the gas are removed mainly by spraying. Then, the gas passes through multiple absorption layers, which can absorb harmful substances in the gas. Through this series of processes, the gas is finally purified.
[0003] In the process of chemical dust treatment, multi-stage spray washing towers are also needed. After long-term use, the inner wall of the currently used washing towers will accumulate dust particles, resulting in a decrease in the cleaning quality of the washing tower. As a result, the multi-stage spray washing towers for chemical dust treatment on the market have added a cleaning mechanism to clean the inner wall of the tower body. Specifically, a washing chamber and a cleaning mechanism are set inside the washing tower body. The cleaning mechanism consists of a funnel frame, a scraper ring and a connecting rope. A fixed rod is set in the washing chamber with a movable hole at the top. The scraper ring slides on the inner wall of the washing chamber. There is a drain pipe at the bottom of the funnel frame. The connecting rope passes through the movable hole to connect the scraper ring and the funnel frame; when spraying water, the speed of water flowing into the funnel frame is greater than the drainage speed, and the funnel frame moves downward to drive the scraper ring to move upward to clean the inner wall. After the water spraying stops, the water in the funnel frame is drained, and the scraper ring moves downward to clean again; in addition, the outer wall of the washing tower is provided with an air inlet pipe, an exhaust pipe, a water inlet pipe and a water outlet pipe, and the nozzle of the water inlet pipe sprays water for spraying treatment; this solution improves the cleaning quality of the inner wall of the washing tower through this special cleaning mechanism design. At the same time, there are also plot structures on the market that are composed of scrapers and other components arranged inside the tower body, which are mainly used to clean the inner wall of the washing tower.
[0004] However, during the actual use of the multi-stage spray washing tower for chemical dust treatment mentioned above, it is necessary to regularly check the condition of the drain pipe, such as whether there is blockage, damage, etc. If any problems are found, they should be maintained or replaced in time. Traditional washing tower drain pipes are usually fixed to the tower body by welding. When the drain pipe needs to be maintained or replaced, the disassembly process is relatively cumbersome and the whole process takes a relatively long time. In addition, during the maintenance or replacement process, the washing tower needs to be stopped, which undoubtedly increases the maintenance cost. These problems have seriously affected the normal operation of the washing tower and need to be solved urgently. Utility Model Content

[0011] By adopting the above technical solution, the sealing of the water pipe and the drainage pipe after connection is ensured, and the drainage pipe can be disassembled while ensuring the sealing effect during use.
[0012] Furthermore, the cleaning ring is located above the water diversion pipe, and when the cleaning ring is not sliding, it does not contact the water diversion pipe, and when the cleaning ring slides, it sticks to the inner wall of the water diversion pipe.
[0013] By adopting the above technical solution, it is ensured that the cleaning ring will not affect the normal use of the water pipe, and at the same time it is ensured that the cleaning ring will clean the water pipe when the drain pipe is disassembled.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0032] The following describes an embodiment of the present invention based on its overall structure.
[0033] Chemical dust treatment uses a multi-stage spray scrubber, such as Figure 1 - Figure 6 As shown, the device includes a main body, which includes a spray tower 1 and a water diversion pipe 2. A drain pipe 3 is provided at the bottom of the water diversion pipe 2. A connecting groove 4 corresponding to the bottom end of the water diversion pipe 2 is provided at the top of the drain pipe 3, so that the drain pipe 3 and the water diversion pipe 2 are detachably connected, so that the drain pipe 3 and the water diversion pipe 2 can slide between them, thereby facilitating the user to remove the drain pipe 3 for maintenance and replacement;
[0034] At the same time, a connecting frame 5 is movably installed on the outer wall of the drain pipe 3, and a connecting block 6 threadedly connected to the connecting frame 5 is installed on the outer wall of the water diversion pipe 2. When the bottom end of the water diversion pipe 2 enters the drain pipe 3, the connecting frame 5 is rotated so that it will be threadedly connected to the connecting block 6, thereby fixing the connection between the water diversion pipe 2 and the drain pipe 3, ensuring the fixed position of the water diversion pipe 2 and the drain pipe 3 during use.
[0035] This embodiment further installs a support frame 7 in the drain pipe 3, and a cleaning ring 8 for cleaning the water pipe 2 is installed on the top of the support frame 7, so that when the drain pipe 3 is raised and lowered, the cleaning ring 8 will be driven by the support frame 7 to move up and down, so that when the drain pipe 3 is removed, the cleaning ring 8 will scrape the inner wall of the water pipe 2, thereby improving the cleanliness of the inner wall of the water pipe 2.
[0036] See also Figure 2 - Figure 6The diameter of the part of the water diversion pipe 2 below the installation connection block 6 is smaller than the diameter of the connection position between the water diversion pipe 2 and the spray tower 1, ensuring that the bottom of the water diversion pipe 2 can smoothly enter the connection groove 4, thereby ensuring that the water diversion pipe 2 can be smoothly connected to the drain pipe 3, and the bottom end and the outer wall of the bottom end of the water diversion pipe 2 are both in contact with the connection groove 4, thereby increasing the sealing of the connection position between the water diversion pipe 2 and the drain pipe 3, and because the bottom end of the connection block 6 is in contact with the top of the drain pipe 3, when the user rotates the connection frame 5, the connection sealing between the connection block 6 and the drain pipe 3 will be further improved. At the same time, because the connection position between the water diversion pipe 2 and the connection groove 4 and the connection position between the connection block 6 and the drain pipe 3 are both provided with sealing rings, the sealing of the water diversion pipe 2 and the drain pipe 3 after connection is further improved.
[0037] See also Figure 2 - Figure 6 The cleaning ring 8 in this embodiment is located above the water pipe 2, and the cleaning ring 8 does not contact the water pipe 2 when it is not sliding, so that the cleaning ring 8 will not block the water pipe 2 during normal use. Only when the user is disassembling and installing the drain pipe 3 will the cleaning ring 8 slide in the water pipe 2, and when the cleaning ring 8 slides, it will stick to the inner wall of the water pipe 2. At this time, the cleaning ring 8 will scrape the inner wall of the water pipe 2 to improve the cleanliness of the water pipe 2.
[0038] See also Figure 1 - Figure 4 In this embodiment, the device body further includes a supporting mechanism, and the supporting mechanism includes a support leg 11 fixedly mounted on the bottom of the spray tower 1 for supporting the spray tower 1;
[0039] The supporting mechanism specifically includes a positioning block 9 fixedly installed in the connecting groove 4, and a positioning groove 10 corresponding to the positioning block 9 is opened on the outer wall of the bottom end of the water diversion pipe 2, so that in the process of docking the drain pipe 3 with the water diversion pipe 2, the positioning block 9 will enter the positioning groove 10 synchronously with the connection of the drain pipe 3 and the water diversion pipe 2, so as to ensure the fixed angle of the connection position of the drain pipe 3 and the water diversion pipe 2. At the same time, multiple groups of positioning blocks 9 are installed at equal angles in the connecting groove 4, further improving the limiting effect of the drain pipe 3 and the water diversion pipe 2.
[0040] Furthermore, the support mechanism in this embodiment also includes a support plate 13 fixedly mounted on the outer wall of the support leg 11, and a limiting rod 14 is installed at the bottom of the support plate 13, and a limiting frame 12 is also installed on the outer wall of the end of the drain pipe 3, which is slidably connected to the drain pipe 3, so that when the drain pipe 3 slides, it will drive the limiting frame 12 to slide synchronously. At this time, the limiting frame 12 will slide on the limiting rod 14, and the drain pipe 3 is supported and limited by the limiting rod 14, thereby ensuring the stability of the drain pipe 3 during the lifting and lowering movement and the fixed angle of the drain pipe 3 after installation, thereby reducing the difficulty of disassembling the drain pipe 3.
[0041] For some examples, see Figure 3 , the limit frames 12 and the limit rods 14 are symmetrically installed in multiple groups on both sides of the drain pipe 3, further ensuring the stability of the drain pipe 3 during movement and the fixity after installation. At the same time, because the length of the limit rod 14 is greater than the length of the support frame 7, when the drain pipe 3 drives the cleaning ring 8 to move downward through the support frame 7 to the state where the cleaning ring 8 is separated from the water diversion pipe 2, the limit frame 12 is still located on the limit rod 14 at this time, so as to ensure that during the installation and removal of the drain pipe 3, the cleaning ring 8 can smoothly and steadily enter and slide out of the water diversion pipe 2.
[0042] In this embodiment, corresponding magnets are embedded in the top of the limit frame 12 and the position where the limit rod 14 is installed on the support plate 13, and the magnets in the limit frame 12 are magnetically attracted to the magnets in the support plate 13. When the drain pipe 3 and the water diversion pipe 2 are connected and fixed, the top of the limit frame 12 will be attached to the bottom of the support plate 13, and the two groups of magnets will be magnetically attracted to each other, thereby improving the stability of the drain pipe 3. At the same time, after the user rotates the connecting frame 5 to separate it from the connecting block 6, the two magnets will cooperate with the limit frame 12, the limit rod 14 and the cleaning ring 8 to prevent the drain pipe 3 from falling quickly, causing an accident where it falls to the ground.
[0043] The working principle of the present invention is as follows: first, under normal use, the water diversion pipe 2 and the drainage pipe 3 are in a connected state; because the diameter of the portion below the water diversion pipe 2 where the connecting block 6 is installed is smaller than the diameter of the connection position with the spray tower 1, this allows the bottom of the water diversion pipe 2 to smoothly enter the connecting groove 4 at the top of the drainage pipe 3; the bottom end and the outer wall of the bottom end of the water diversion pipe 2 are in contact with the connecting groove 4, and the bottom end of the connecting block 6 is in contact with the top of the drainage pipe 3, as well as the sealing rings provided at the connection positions of the water diversion pipe 2 and the connecting groove 4, and the connecting block 6 and the drainage pipe 3, together ensure the sealing of the connection position between the water diversion pipe 2 and the drainage pipe 3; and because the cleaning ring 8 is located above the water diversion pipe 2, it does not contact the water diversion pipe 2 during normal use and will not cause any obstruction to the water diversion pipe 2;
[0044] When the drain pipe 3 needs to be maintained or replaced, the disassembly operation begins; the connecting frame 5 on the outer wall of the drain pipe 3 is rotated to separate it from the connecting block 6 on the outer wall of the water diversion pipe 2; since the drain pipe 3 and the water diversion pipe 2 are detachably connected and slidable, the drain pipe 3 can be easily removed at this time; when the drain pipe 3 is raised and lowered to prepare for removal, the support frame 7 inside the drain pipe 3 will drive the cleaning ring 8 to rise and fall; when the cleaning ring 8 slides, it will stick to the inner wall of the water diversion pipe 2, scraping the inner wall of the water diversion pipe 2 to improve the cleanliness of the inner wall of the water diversion pipe 2;
[0045] During the installation process of the drainage pipe 3 and the water diversion pipe 2, the positioning block 9 in the connection groove 4 will simultaneously enter the positioning groove 10 on the outer wall of the bottom end of the water diversion pipe 2 as the drainage pipe 3 and the water diversion pipe 2 are connected, thereby ensuring the fixed angle of the connection position of the drainage pipe 3 and the water diversion pipe 2;
[0046] When the drain pipe 3 slides, it will drive the limit frame 12 to slide synchronously. The limit frame 12 slides on the limit rod 14, and the drain pipe 3 is supported and limited by the limit rod 14, ensuring the stability of the drain pipe 3 during lifting and lowering movement and the fixed angle after installation, reducing the difficulty of disassembling the drain pipe 3; when the drain pipe 3 drives the cleaning ring 8 to move downward through the support frame 7 to the state where the cleaning ring 8 is separated from the water diversion pipe 2, the limit frame 12 is still located on the limit rod 14, ensuring that during the installation and disassembly of the drain pipe 3, the cleaning ring 8 can smoothly and steadily enter and slide out of the water diversion pipe 2.
[0047] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
