Description

Technical Field

[0001] This utility model relates to the field of crystallization tanks, and in particular to a double-layer crystallization tank for wastewater treatment. Background Technology

[0002] Double-layer crystallizers for wastewater treatment are mainly used for crystallizing saline industrial wastewater. The double-layer structure provides better temperature control, and the crystallization process can be more precisely controlled by adjusting the temperature difference between the inner and outer layers.

[0003] Utility model CN220056384U discloses a high-salt wastewater crystallization device. Its key technical features include: a tank, a drive assembly, a stirring assembly, and a feeding assembly; the drive assembly is fixedly connected to the top of the tank, the stirring assembly is rotatably connected to the tank, and the stirring assembly is also drively connected to the drive assembly; the feeding assembly is fixedly installed inside the top of the tank; the top of the tank also has an air inlet and an air outlet; the bottom of the tank has a discharge outlet for discharging crystals; and the bottom of the tank also has a liquid outlet for discharging saline wastewater. This utility model changes the heat exchange method for saline wastewater by using air cooling to cool the saline wastewater, then using the crystals precipitated in the liquid as crystallization nuclei, and then using stirring to make the crystals grow continuously. Wastewater cooling and crystallization is surface heat exchange, which can effectively prevent crystals from adhering to the tank wall of the equipment. At the same time, stirring can effectively solve the problems of internal deposition and agglomeration in existing saline wastewater crystallization devices.

[0004] Regarding the above-mentioned issues, the following technical defects were found: the height of the crystallization tank in the existing technology cannot be adjusted during use, which in turn makes it impossible to adjust the height of the feed pipe and the discharge pipe. If the feed pipe is too high, workers will need to use high-altitude work tools when discharging wastewater. If the discharge pipe is too low, workers will need to bend over, squat down, or even be unable to directly contact the discharge pipe and will need to use tools to operate it, which reduces the convenience and practicality of using the crystallization tank.

[0005] Therefore, it is necessary to provide a new type of double-layer crystallization tank for wastewater treatment to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a double-layer crystallization tank for wastewater treatment.

[0007] To solve the above-mentioned technical problems, this utility model provides a double-layer crystallization tank for wastewater treatment, including: an outer tank, a rotating mechanism, and an installation mechanism. An inner tank is installed inside the outer tank. A discharge pipe is installed on the lower surface of the outer tank and is connected to the inner tank. Several heating pipes are installed on the outer wall of the inner tank. A tank cover is installed at the upper end of the outer tank. A feed pipe is fixedly connected to the outer wall of the tank cover. The installation mechanism is disposed on the outer wall of the outer tank. The rotating mechanism is disposed on the outer tank by means of the installation mechanism. The rotating mechanism includes a support plate and an arched plate. The inner wall of the arched plate is in contact with the outer wall of the outer tank. A rotating shaft is rotatably inserted through the side of the long arm end of the support plate. One end of the rotating shaft is fixedly connected to the arched plate, and the other end of the rotating shaft is fixedly connected to a turntable. A cylinder is fixedly connected to the side of the long arm end of the support plate away from the arched plate. A rotating seat is fixedly connected to the output end of the cylinder. A connecting rod is rotatably connected to the inner wall of the rotating seat. The end of the connecting rod away from the rotating seat is rotatably connected to the centrifugal position of the turntable away from the rotating shaft.

[0008] The effect achieved by the above components is as follows: by setting up a rotating mechanism, the crystallizer can be automatically rotated before feeding or discharging operations, thereby adjusting the height of the feed pipe and the discharge pipe. This avoids the feed pipe being too high or the discharge pipe being too low, which would affect the feeding and discharging operations, and improves the ease of use and practicality of the crystallizer.

[0009] Preferably, the turntable has an annular hole on its arc surface, and a plurality of positioning plates are slidably connected to the inner wall of the annular hole. The positioning plates are fixedly connected to the side of the long arm end of the support plate away from the arched plate.

[0010] The effect achieved by the above components is that when the connecting rod drives the turntable to rotate, the positioning plate fixed on the support plate will slide along the inner wall of the annular hole on the turntable, thereby improving the stability of the turntable rotation process.

[0011] Preferably, a sliding hole is provided on the side of the long arm end of the support plate, and a sliding rod is slidably connected to the inner wall of the sliding hole. One end of the sliding rod is fixedly connected to the side of the arched plate near the support plate. The cross-section of the sliding hole is arc-shaped, and the center of the sliding hole is coaxial with the axis of rotation of the rotating shaft.

[0012] The effect achieved by the above components is that when the rotating shaft drives the arched plate and the crystallizing tank to rotate, the sliding rod fixed on the arched plate will slide along the inner wall of the sliding hole, thereby improving the stability of the arched plate rotation process.

[0013] Preferably, a rubber pad is fixedly connected to the lower surface of the short arm end of the support plate, and the rubber pad is adapted to the size of the lower surface of the support plate.

[0014] The effect achieved by the above components is that the rubber pad can increase the friction on the lower surface of the support plate, thereby enabling the support plate to be stably supported on the ground.

[0015] Preferably, the installation mechanism includes two mounting holes and two fixing blocks. The two mounting holes are respectively opened on both sides of the arched plate, and the two fixing blocks are fixed to the outer wall of the outer tank. The fixing blocks are slidably inserted into the inner wall of the mounting holes. The two arched plates are rotatably connected to the opposite sides with lead screws. The arc surface of the lead screws is threaded with an adjusting plate. The side of the adjusting plate is provided with a fixing hole, and the fixing hole is adapted to the size of the fixing block.

[0016] The effect achieved by the above components is that, by setting up the installation mechanism, personnel can easily disassemble and install the rotating mechanism from the crystallization tank, thereby facilitating the maintenance and replacement of the rotating mechanism and increasing the flexibility of equipment use.

[0017] Preferably, a plurality of guide rods are slidably provided on the side of the adjusting plate, and one end of the guide rods is fixedly connected to the arched plate.

[0018] The effect achieved by the above components is that when the lead screw drives the adjusting plate to move, the guide rod can guide and position the adjusting plate, thereby improving the stability of the adjusting plate movement process.

[0019] Preferably, the mounting hole, the fixing block, and the fixing hole all have rectangular cross-sections.

[0020] The effect achieved by the above components is that by setting the cross-section of the mounting hole, the fixing block, and the fixing hole to be rectangular, the connection between the fixing block and the mounting hole can be made more stable.

[0021] Compared with related technologies, the double-layer crystallization tank for wastewater treatment provided by this utility model has the following beneficial effects:

[0022] By setting up a rotating mechanism, the crystallizer can be automatically rotated before feeding or discharging operations, thereby adjusting the height of the feed pipe and discharge pipe.

[0030] 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.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figure 1 and Figure 2 The present invention provides a double-layer crystallization tank for wastewater treatment, comprising: an outer tank 1, a rotating mechanism 3 and an installation mechanism 4. An inner tank 5 is installed inside the outer tank 1. A discharge pipe 2 is installed on the lower surface of the outer tank 1 and is connected to the inner tank 5. A plurality of heating pipes 6 are installed on the outer wall of the inner tank 5. A tank cover 7 is installed at the upper end of the outer tank 1, and a feed pipe 8 is fixedly connected to the outer wall of the tank cover 7.

[0033] The installation mechanism 4 is installed on the outer wall of the outer tank 1, and the rotating mechanism 3 is installed on the outer tank 1 with the help of the installation mechanism 4.

[0034] In the embodiments of this utility model, please refer to Figure 3 and Figure 4The rotating mechanism 3 includes a support plate 301 and an arched plate 305. The inner wall of the arched plate 305 is in contact with the outer wall of the outer tank 1. A rotating shaft 306 is rotatably inserted through the side of the long arm end of the support plate 301. One end of the rotating shaft 306 is fixedly connected to the arched plate 305, and the other end of the rotating shaft 306 is fixedly connected to a turntable 307. A cylinder 302 is fixedly connected to the side of the long arm end of the support plate 301 away from the arched plate 305. A rotating seat 303 is fixedly connected to the output end of the cylinder 302. A connecting rod 304 is rotatably connected to the inner wall of the rotating seat 303. The connecting rod 304 is located away from the inner wall of the arched plate 305. One end of the rotating seat 303 is rotatably connected to the centrifugal position of the turntable 307 away from the rotating shaft 306. By setting the rotating mechanism 3, the crystallizer can be automatically rotated before feeding or discharging operations, thereby adjusting the height of the feed pipe 8 and the discharge pipe 2. This prevents the feed pipe 8 from being too high or the discharge pipe 2 from being too low, thus avoiding interference with feeding and discharging operations and improving the ease of use and practicality of the crystallizer. The turntable 307 has an annular hole 308 on its arc surface, and several positioning plates 309 are slidably connected to the inner wall of the annular hole 308. Positioning plate 309 is fixedly connected to the side of the long arm end of support plate 301 away from arched plate 305. When connecting rod 304 drives turntable 307 to rotate, positioning plate 309 fixed on support plate 301 will slide along the inner wall of annular hole 308 on turntable 307, thereby improving the stability of turntable 307 during rotation. A sliding hole 310 is provided on the side of the long arm end of support plate 301. A sliding rod 311 is slidably connected to the inner wall of sliding hole 310. One end of sliding rod 311 is fixedly connected to the side of arched plate 305 near support plate 301. The cross-section of sliding hole 310 is arc-shaped. The center of the hole 310 is coaxial with the axis of rotation of the rotating shaft 306. When the rotating shaft 306 drives the arched plate 305 and the crystallizing tank to rotate, the sliding rod 311 fixed on the arched plate 305 will slide along the inner wall of the sliding hole 310, thereby improving the stability of the arched plate 305 during rotation. A rubber pad 312 is fixedly connected to the lower surface of the short arm end of the support plate 301. The size of the rubber pad 312 is matched with the lower surface of the support plate 301. The rubber pad 312 can improve the friction of the lower surface of the support plate 301, thus achieving the effect of making the support plate 301 stable on the ground.

[0035] In the embodiments of this utility model, please refer to Figure 5The installation mechanism 4 includes two mounting holes 41 and two fixing blocks 42. The two mounting holes 41 are respectively opened on both sides of the arched plate 305. The two fixing blocks 42 are fixed to the outer wall of the outer tank 1 and are slidably inserted into the inner wall of the mounting holes 41. The two arched plates 305 are rotatably connected to the opposite sides with screw rods 43. The arc surface of the screw rods 43 is threadedly connected to an adjusting plate 44. The side of the adjusting plate 44 has a fixing hole 45, which is adapted to the size of the fixing block 42. By setting up the installation mechanism 4, personnel can easily disassemble and install the rotating mechanism 3 from the crystallization tank, thereby facilitating the maintenance of the rotating mechanism 3. The adjustment plate 44 is slidably provided with several guide rods 46 on its side. One end of the guide rod 46 is fixedly connected to the arched plate 305. When the screw 43 is rotated to move the adjustment plate 44, the guide rods 46 can guide and position the adjustment plate 44, thereby improving the stability of the adjustment plate 44 during movement. The cross-sections of the mounting hole 41, the fixing block 42, and the fixing hole 45 are all rectangular. By setting the cross-sections of the mounting hole 41, the fixing block 42, and the fixing hole 45 to be rectangular, the connection between the fixing block 42 and the mounting hole 41 and the fixing block 42 and the fixing hole 45 can be made more stable.

[0036] The working principle of the double-layer crystallizer for wastewater treatment provided by this utility model is as follows: The double-layer crystallizer has a double-layer structure of an inner tank 5 and an outer tank 1. The heating pipe 6 installed between the inner tank 5 and the outer tank 1 can heat the saline wastewater inside the inner tank 5 to assist the saline wastewater in crystallization reaction. In use, the wastewater to be treated is put into the inner tank 5 through the feed pipe 8. The treated wastewater will finally be discharged from the discharge pipe 2. During the feeding or discharging process, the crystallizer needs to be rotated to adjust the feed pipe. When the height of the discharge pipe 2 is 8, first start the cylinder 302 to drive the rotating seat 303 to move. The rotating seat 303 drives the connecting rod 304 to rotate along the inner wall of the rotating seat 303. At the same time, the connecting rod 304 will drive the turntable 307 to rotate. When the connecting rod 304 drives the turntable 307 to rotate, the positioning plate 309 fixed on the support plate 301 will slide along the inner wall of the annular hole 308 on the turntable 307, thereby improving the stability of the turntable 307 during rotation. 7. During rotation, the rotating shaft 306 will rotate, which in turn will drive the arched plate 305 to rotate. The arched plate 305 will then drive the crystallizer to rotate, thereby adjusting the height of the feed pipe 8 and the discharge pipe 2. Once the feed pipe 8 and the discharge pipe 2 are adjusted to the appropriate height, the operation of the cylinder 302 can be stopped. After the feeding or discharging operation is completed, the cylinder 302 is started to drive the rotating seat 303 to move in the opposite direction. The rotating seat 303 will then drive the connecting rod 304 to move in the opposite direction, and the connecting rod 304 will then drive... The turntable 307 rotates in the opposite direction, thereby causing the turntable 307 to drive the arched plate 305 and the crystallization tank, causing the crystallization tank to rotate and reset. When the rotating shaft 306 drives the arched plate 305 and the crystallization tank to rotate, the sliding rod 311 fixed on the arched plate 305 will slide along the inner wall of the sliding hole 310, thereby improving the stability of the arched plate 305 during rotation. In addition, the rubber pad 312 can increase the friction of the lower surface of the support plate 301, achieving the effect of making the support plate 301 stable on the ground.

[0037] When the rotating mechanism 3 needs to be installed on the tank, first move the arched plate 305 to fit against the outer wall of the outer tank 1. At the same time, insert the two fixing blocks 42 fixed on the outer tank 1 into the two mounting holes 41 on the arched plate 305. After the fixing blocks 42 are inserted into the inner wall of the mounting holes 41, rotate the screw 43 to drive the adjusting plate 44 to move closer to the fixing blocks 42. When the fixing blocks 42 are inserted into the fixing holes 45 on the adjusting plate 44, the installation of the rotating mechanism 3 is completed. When the rotating mechanism 3 needs to be disassembled, first rotate the screw 43 to drive the adjusting plate 44 and... The fixing hole 45 is separated from the fixing block 42, and then the arched plate 305 is moved to separate the mounting hole 41 from the fixing block 42, thus completing the disassembly of the rotating mechanism 3. When the rotating screw 43 moves the adjusting plate 44, the guide rod 46 can guide and position the adjusting plate 44, thereby improving the stability of the adjusting plate 44 during movement. In addition, by setting the cross sections of the mounting hole 41, the fixing block 42, and the fixing hole 45 to rectangles, the connection between the fixing block 42 and the mounting hole 41 and the fixing block 42 and the fixing hole 45 can be made more stable.

[0038] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
