Description

Technical Field

[0001] This utility model relates to the field of acid mist spraying towers, and more particularly to a self-circulating acid mist spraying tower that is clogging-resistant. Background Technology

[0002] Acid mist towers, also known as acid mist purification towers, acid gas purification towers, acid mist absorption towers, waste gas purification towers, and fiberglass acid mist purification towers, are capable of removing harmful gases from the air. They have a wide range of applications, extremely high purification efficiency, low equipment resistance, and a small footprint, making them commonly used in chemical plants. However, when the water source after spraying and returning from the acid mist tower is recycled, the particles and other impurities it carries can clog the pipes, causing them to malfunction.

[0003] A Chinese patent publication number CN210544228U describes an anti-clogging acid mist tower spray pump pipeline. According to its description, when the inclined filter plate in the device becomes clogged, the machine needs to be stopped for cleaning. This not only increases the difficulty of cleaning the inclined plate but also affects the working efficiency of the device to some extent.

[0004] Therefore, it is necessary to provide a new anti-clogging self-circulating acid mist spraying tower to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a self-circulating acid mist spraying tower that is clogging-proof.

[0006] The anti-clogging self-circulating acid mist spraying tower provided by this utility model includes: a spraying tower and a dosing tank, wherein a conveying component is provided between the spraying tower and the dosing tank;

[0007] The delivery assembly includes a delivery pump, the input end of which is provided with a three-way pipe, the three-way pipe being connected to the spray tower and the dosing tank, and the output end of the delivery pump being provided with a conduit, and the conduit being provided with a filter assembly for filtering the liquid.

[0008] The filter assembly includes two adapter pipes connected to a conduit. The adapter pipes are equipped with symmetrically distributed solenoid valves. A mounting groove is provided below the solenoid valves on the side wall of the adapter pipe. A filter plate is inserted into the mounting groove and fixedly connected by bolts. The filter plate has several evenly distributed filter holes inside, and a pressure sensor is provided at the center of the top of the filter plate.

[0009] Preferably, two fixedly connected support frames are provided between the two solenoid valves inside the transfer pipe, and a rotating rod is rotatably connected between the two support frames, and blades are provided on the outer wall of the rotating rod.

[0010] Preferably, the top of the support frame is provided with symmetrically distributed telescopic rods, and the top of the two telescopic rods is provided with the same fixedly connected adapter frame.

[0011] Preferably, the top of the adapter frame is provided with a plurality of evenly distributed pins, the position of the pins is opposite to the position of the filter holes, and the diameter of the pin end is smaller than the diameter of the filter holes.

[0012] Preferably, the top of the rotating rod is provided with a fixedly connected extrusion rod, the extrusion rod is located below the adapter frame, and both sides of the bottom of the adapter frame are provided with symmetrically distributed inclined blocks, the sidewalls of the inclined blocks are inclined surfaces, and the inclined blocks are located on the rotation trajectory of the extrusion frame.

[0013] Preferably, the conveying assembly further includes a conveying pipe, which is connected to the spray tower and the transfer pipe.

[0014] Compared with related technologies, the anti-clogging self-circulating acid mist spraying tower provided by this utility model has the following beneficial effects:

[0015] 1. When using this utility model, the pressure sensor can detect the pressure above the filter plate inside the corresponding rotating tube. When the pressure is greater than the upper limit of the set value, the solenoid valve on the other rotating tube can be opened and the solenoid valve on the corresponding rotating tube can be closed, thereby realizing the replacement and cleaning of the filter plate without stopping the machine.

[0016] 2. When this utility model is in use, the flowing liquid will drive the rotating rod to rotate through the blades. At this time, the squeezing rod on the rotating rod will drive the ejector pin to move vertically by squeezing with the inclined block. This allows the ejector pin to clean the substances clogging the filter holes, thereby reducing the probability of the blockage continuously accumulating in the filter holes and causing the entire filter plate to become clogged.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] Please see Figures 1 to 5 The present invention provides a clog-resistant self-circulating acid mist spraying tower, which includes a spraying tower 1 and a dosing tank 2, with a conveying assembly 3 provided between the spraying tower 1 and the dosing tank 2.

[0026] Please refer to the figures for embodiments of this utility model. Figures 1 to 5 The conveying assembly 3 includes a conveying pump 31. The input end of the conveying pump 31 is provided with a three-way pipe 311, which is connected to the spray tower 1 and the dosing tank 2. The output end of the conveying pump 31 is provided with a conduit 312. The conveying assembly 3 also includes a conveying pipe 32, which is connected to the spray tower 1 and the transfer pipe 41. The conduit 312 is provided with a filter assembly 4 for filtering the liquid. The filter assembly 4 includes a transfer pipe 41. There are two transfer pipes 41, which are connected to the conduit 312. The transfer pipe 41 is provided with symmetrically distributed solenoid valves 412. An installation groove 411 is opened below the solenoid valves 412 on the side wall of the transfer pipe 41. A filter plate 42 is inserted into the installation groove 411 and fixedly connected by bolts. The filter plate 42 has several evenly distributed filter holes 421 inside. A pressure sensor 422 is provided at the center of the top of the filter plate 42.

[0027] It should be noted that by connecting the three-way pipe 311 to the delivery pump 31, the spray tower 1 and the dosing tank 2, during use, the working delivery pump 31 can smoothly draw in and deliver the liquid returning after spraying from the spray tower 1 and the liquid inside the dosing tank for spraying.

[0028] When the transported liquid passes through the transfer pipe 41, if impurities in the return liquid cause blockage inside the filter hole 421, the pressure above the filter plate 42 inside the transfer pipe will increase. During this process, the terminal controller can detect the pressure status in real time through the pressure sensor 422. When the pressure exceeds the upper limit of the set value, the solenoid valve 412 on the other transfer pipe 41 will be opened and the solenoid valve 412 on the corresponding transfer pipe 41 will be closed. At this time, the operator can disassemble and clean the blocked filter plate 42 without stopping the machine, thereby reducing the impact of cleaning the filter plate 42 on the working efficiency of the device during later use.

[0029] Please refer to the figures for embodiments of this utility model. Figures 1 to 5 Inside the adapter tube 41, two fixedly connected support frames 43 are mounted between two solenoid valves 412. A rotating rod 431 is mounted between the two support frames 43, and blades 433 are provided on the outer wall of the rotating rod 431. Symmetrically distributed telescopic rods 44 are provided on the top of the upper support frame 43, and the same fixedly connected adapter frame 441 is mounted on the top of the two telescopic rods 44. Multiple evenly distributed ejector pins 442 are provided on the top of the adapter frame 441. The position of the ejector pins 442 is opposite to the position of the filter hole 421, and the diameter of the end of the ejector pin 442 is smaller than the diameter of the filter hole 421. A fixedly connected extrusion rod 432 is provided on the top of the rotating rod 431. The extrusion rod 432 is located below the adapter frame 441. Symmetrically distributed inclined blocks 443 are provided on both sides of the bottom of the adapter frame 441. The side walls of the inclined blocks 443 are inclined, and the inclined blocks 443 are located on the trajectory of the extrusion frame rotation.

[0030] It should be noted that during use, when the liquid flows downward from the inside of the filter hole 421, it drives the blade 433 to rotate. At this time, the blade 433 drives the internal rotating rod 431 and the top squeezing rod 432 to rotate. When the outer wall of the squeezing rod 432 abuts against the outer wall of the inclined block 443, the inclined surface of the side wall of the inclined block 443 will transform the horizontal rotation force of the rotating rod 431 into a vertical squeezing force on the inclined block 443. This allows the ejector pin 442 to move upward to lift and clean the blockage inside the filter hole 421. When the rotating rod 431 moves to the side wall of the inclined block 443, the ejector pin 442 will slide out of the filter hole 421 under the force of the water flow. This allows the ejector pin 442 to perform reciprocating lifting and cleaning, thus reducing the probability of blockage inside the filter hole 421.

[0031] The working principle of the anti-clogging self-circulating spray acid mist tower provided by this utility model is as follows;

[0032] When using this device, first open the solenoid valve 412 on one of the transfer pipes 41 in the filter assembly 4, and then control the delivery pump 31 in the delivery assembly 3 to work. The working delivery pump 31 can suck up the liquid medicine in the spray tower 1 and the dosing tank 2 and deliver it to the inside of the transfer pipe 41 through the conduit 312. The liquid medicine flowing in from the inside of the transfer pipe 41 will be delivered and sprayed into the spray tower 1 through the delivery pipe 32.

[0033] When the liquid medicine flows into the inside of the transfer tube 41, the filter plate 42 located above the inside of the transfer tube 41 filters the liquid medicine flowing in through the internal filter holes 421. The liquid medicine flowing downward from the inside of the filter holes 421 drives the blades 433 to rotate. At this time, the blades 433 drive the internal rotating rod 431 and the top squeezing rod 432 to rotate. When the outer wall of the squeezing rod 432 abuts against the outer wall of the inclined block 443, the inclined surface of the side wall of the inclined block 443 will transform the horizontal rotation force of the rotating rod 431 into a vertical squeezing force on the inclined block 443. This allows the ejector pin 442 to move upward to lift and clean the substances clogging the inside of the filter holes 421. When the rotating rod 431 moves to the side wall of the inclined block 443, the ejector pin 442 will slide out from the filter holes 421 under the force of the water flow. This allows the ejector pin 442 to perform reciprocating lifting and cleaning, thus reducing the probability of clogging inside the filter holes 421.

[0034] During continuous use, the terminal controller can also detect the water pressure above the transfer pipe 41 in real time through the pressure sensor 422 on the filter plate 42. When the filter plate 42 is blocked and the pressure value above it exceeds the set upper limit, the solenoid valve 412 on the corresponding transfer pipe 41 will be automatically closed and the solenoid valve 412 on the other transfer pipe 41 will be opened, so that the liquid input by the delivery pump 31 can flow smoothly. During this process, the staff can clean the filter plate 42 without stopping the machine, thus reducing the impact of cleaning the filter plate 42 on the work efficiency during the later use of this device.

[0035] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0036] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
