Description

Technical Field

[0001] This utility model relates to the technical field of water treatment, and in particular to a scraper lifting mechanism for a scale and bacteria removal device. Background Technology

[0002] Scale and bacteria remover (commonly known as electrochemical water treatment equipment) is a device that utilizes the electrochemical properties of anions and cations in water to solve the problems of scaling and microbial control in circulating cooling water systems. It mainly works by applying direct current between the anode and cathode plates. Through the principle of electroadsorption, a large amount of scale forms in the strongly alkaline environment of the cathode region, while a highly oxidizing bactericidal substance is generated in the strongly acidic environment of the anode region. By controlling the Langelinie index (LSI) and stability index of the water, the salt balance in the water is regulated, thereby achieving the purpose of controlling scaling and sterilization.

[0003] Statistics show that industrial water consumption accounts for 21.6% of total water consumption, while circulating water consumption accounts for 70% to 80% of industrial water consumption. Therefore, saving cooling circulating water is the most effective measure to save industrial water. Scale and bacteria cleaner, as a new type of energy-saving equipment, is gradually being used in the field of industrial circulating water treatment, replacing the original chemical agent method. After using scale and bacteria cleaner equipment, the industrial circulating water system can achieve a higher concentration ratio (generally 6 to 8 times), saving water resources and solving the problem of secondary pollution. Because the system drainage does not contain the high concentration of phosphorus and bactericides brought about by the chemical method, and the hardness and conductivity are significantly reduced, it is conducive to the subsequent reuse treatment of wastewater.

[0004] Because the scale removal equipment needs to use an elevator to completely lift the scraper out of the cathode plate area of ​​the main body of the equipment during operation, the maximum stroke of the elevator is greater than the height of the scraper. Therefore, when the lower end of the scraper reaches the lower end of the cathode plate, the elevator is not at its limit position. Due to the above technical characteristics, the lower end of the scraper often falls below the lower end of the cathode plate during the operation of the scale removal equipment, that is, the lower end of the scraper gets stuck in the conical slag discharge hopper. Utility Model Content

[0005] To reduce the probability of the scraper getting stuck in the conical slag discharge hopper during cleaning, this application provides a scraper lifting mechanism for a scale and bacteria cleaning device.

[0006] The scraper lifting mechanism of the scale and bacteria removal equipment provided in this application adopts the following technical solution:

[0007] A scraper lifting mechanism for a scale and bacteria removal device includes two horizontal beams mounted on the machine body, both of which are connected to a scraper. A power assembly is also mounted on the machine body. Two reinforcing rods are fixedly connected to the end faces of the two horizontal beams that are close to each other, and limit components are mounted on the reinforcing rods.

[0008] By adopting the above technical solution, when the scraper is working, the power component drives the horizontal beam to move, the horizontal beam drives the scraper to clean, and at the same time the horizontal beam drives the reinforcing rod to move. When it moves to the position of the lower end of the cathode plate, the limiting component blocks the reinforcing rod, thereby reducing the probability that the lower end of the scraper will get stuck in the conical slag discharge hopper. At the same time, the frame structure connects all the scrapers into a whole structure, replacing the original multiple independent scraper structures, which has strong integrity, is more stable, and is less prone to failure.

[0009] Optionally, the limiting component includes a guide rod, which is fixedly connected to the reinforcing rod. A guide seat is installed on the body, and the guide rod is slidably connected to the guide seat. A positioning sleeve is also fixedly connected to the guide rod, and the positioning sleeve is located at the end of the guide rod away from the guide seat.

[0010] By adopting the above technical solution, when the scraper moves to the lower end of the cathode plate, the positioning sleeve on the guide rod abuts against the guide seat, limiting the guide rod and thus limiting the scraper, reducing the probability that the lower end of the scraper will get stuck in the conical slag discharge hopper.

[0011] Optionally, the limiting component includes a connecting rod, which is fixedly connected to the reinforcing rod. A connecting sleeve is fixedly connected to one end of the connecting rod away from the reinforcing rod. A column is also installed on the machine body, which is slidably connected to the connecting sleeve. A limiting ring is fixedly connected to the column.

[0012] By adopting the above technical solution, when the scraper moves to the lower end of the cathode plate, the reinforcing rod drives the connecting sleeve to move through the connecting rod. At this time, the limiting ring abuts against the connecting sleeve to limit the reinforcing rod, thereby limiting the scraper and reducing the probability that the lower end of the scraper will get stuck in the conical slag discharge hopper.

[0013] Optionally, the power assembly includes a motor mounted on the machine body. The machine body is also equipped with a reducer that is driven and connected to the motor. A lead screw is rotatably connected to the machine body. The lead screw is threadedly connected to a lifting mechanism. The lifting mechanism is driven and connected to the reducer and fixedly connected to the horizontal beam.

[0014] By adopting the above technical solution, when the scraper is raised or lowered, the motor starts, and the motor drives the lifting platform to slide on the lead screw through the reducer. The lifting platform drives the horizontal beam to move, and the horizontal beam drives the scraper to rise or fall. The driving force uses the lifting platform instead of the cylinder for scraping, which can solve after-sales problems such as multiple air circuits and easy air leakage. At the same time, the method of motor and reducer, combined with the reduction ratio of the worm gear of the lifting platform, can reduce the lifting speed of the scraper. Compared with the high-speed push of the cylinder, the scraper runs more smoothly and can reduce energy consumption.

[0015] Optionally, the guide rod is also equipped with a detachable component, which includes a fixing plate fixedly connected to the end face of the guide rod near the reinforcing rod. The detachable component also includes a fixing bolt threaded through the fixing plate onto the reinforcing rod.

[0016] By adopting the above technical solution, the setting of the fixing plate and fixing bolts realizes the detachable connection of the guide rod, which facilitates the installation and dismantling of the equipment.

[0017] In summary, this application includes the following beneficial technical effects:

[0018] 1. The frame structure connects all the scrapers into a whole, replacing the original multiple independent scraper structures. This makes the structure more robust, stable, and less prone to failure.

[0019] 2. When the scraper moves to the lower end of the cathode plate, the positioning sleeve on the guide rod abuts against the guide seat, limiting the guide rod and thus limiting the scraper, reducing the probability that the lower end of the scraper will get stuck in the conical slag hopper;

[0020] 3. When the scraper is raised or lowered, the motor starts and drives the lifting platform to slide on the lead screw through the reducer. The lifting platform moves the horizontal beam, and the horizontal beam drives the scraper to rise or fall. The lifting platform replaces the cylinder for scraping, which can solve after-sales problems such as multiple air circuits and easy air leakage.

[0021] 4. By using a motor and reducer, combined with the reduction ratio of the worm gear in the lifting machine, the lifting speed of the scraper can be reduced. Compared with the high-speed push of the cylinder, the scraper runs more smoothly and can reduce energy consumption. Attached Figure Description

[0029] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0030] This application discloses a scraper lifting mechanism for a scale and bacteria removal device.

[0031] Example 1:

[0032] refer to Figure 1 and Figure 2 The scale and bacteria removal equipment scraper lifting mechanism includes two horizontal beams 3 slidably connected to the machine body 1 via a power component 5. Both horizontal beams 3 are fixedly connected to the scraper 2. Two reinforcing rods 4 are fixedly connected to the end faces of the two horizontal beams 3 that are close to each other. The two reinforcing rods 4 are located at both ends of the horizontal beams 3 respectively. A limiting component 6 for limiting the scraper 2 is installed on the reinforcing rods 4.

[0033] When the scraper 2 is in operation, the power unit 5 drives the horizontal beam 3 to move, and the horizontal beam 3 drives the scraper 2 to clean. At the same time, the horizontal beam 3 drives the reinforcing rod 4 to move. When it moves to the lower end of the cathode plate, the limiting component 6 blocks the reinforcing rod 4, thereby reducing the probability that the lower end of the scraper 2 will get stuck in the conical slag discharge hopper. At the same time, the frame structure formed by the two horizontal beams 3 and the two reinforcing rods 4 connects all the scrapers 2 into a whole structure, replacing the original structure of multiple independent scrapers 2. It has strong integrity, is more stable, and is less prone to failure.

[0034] refer to Figure 1 and Figure 2The power component 5 includes a motor 51, which is fixedly connected to the top of the body 1. A reducer 52 is also fixedly connected to the top of the body 1. The reducer 52 is driven by the motor 51. A lead screw 53 is rotatably connected to the body 1. A lifting mechanism 54 is threaded onto the lead screw 53. The lifting mechanism 54 is driven by the reducer 52 and fixedly connected to the reinforcing rod 4. When the scraper 2 is raised or lowered, the motor 51 starts. The motor 51 drives the lifting mechanism 54 to slide on the lead screw 53 through the reducer 52. The lifting mechanism 54 drives the horizontal beam 3 to move, and the horizontal beam 3 drives the scraper 2 to rise or fall. The driving force is the lifting mechanism 54 instead of the cylinder for scraping, which can solve the after-sales problems such as multiple air circuits and easy air leakage. At the same time, the method of the motor 51 and the reducer 52, combined with the reduction ratio of the worm gear of the lifting mechanism 54, can reduce the lifting speed of the scraper 2. Compared with the high-speed push of the cylinder, the scraper 2 runs more smoothly and can reduce energy consumption.

[0035] refer to Figure 3 The limiting component 6 includes a guide rod 61, which is fixedly connected to the reinforcing rod 4. A guide seat 63 is installed on the body 1, and the guide rod 61 is slidably connected to the guide seat 63. A positioning sleeve 62 is also fixedly connected to the guide rod 61, and the positioning sleeve 62 is located at the end of the guide rod 61 away from the guide seat 63. When the scraper 2 moves to the lower end of the cathode plate, the positioning sleeve 62 on the guide rod 61 abuts against the guide seat 63 to limit the guide rod 61, thereby limiting the scraper 2 and reducing the probability that the lower end of the scraper 2 will be stuck in the conical slag discharge hopper.

[0036] refer to Figure 4 The guide rod 61 is also equipped with a detachable component 7, which includes a fixing plate 71. The fixing plate 71 is fixedly connected to the end face of the guide rod 61 near the reinforcing rod 4. The end face of the fixing plate 71 away from the guide rod 61 has multiple through holes 711. The end face of the reinforcing rod 4 near the fixing plate 71 has screw holes 41. The detachable component 7 also includes multiple fixing bolts 72. The multiple fixing bolts 72 pass through the multiple through holes 711 and are threaded into the screw holes 41. The setting of the fixing plate 71 and the fixing bolts 72 realizes the detachable connection of the guide rod 61, thereby facilitating the installation and removal of the equipment.

[0037] The implementation principle of Embodiment 1 of this application is as follows: When the scraper 2 is working, the motor 51 starts, and the motor 51 drives the elevator 54 to slide on the lead screw 53 through the reducer 52. The elevator 54 drives the horizontal beam 3 to move, and the horizontal beam 3 drives the scraper 2 to rise and fall. When the scraper 2 moves to the position of the lower end of the cathode plate, the positioning sleeve 62 on the guide rod 61 abuts against the guide seat 63 to limit the guide rod 61, thereby limiting the scraper 2 and reducing the probability that the lower end of the scraper 2 will be stuck in the conical slag hopper.

[0038] Example 2:

[0039] refer to Figure 5 and Figure 6 The difference between this embodiment and embodiment 1 is that the limiting component 6 includes a connecting rod 64, which is fixedly connected to the reinforcing rod 4. A connecting sleeve 65 is fixedly connected to the end of the connecting rod 64 away from the reinforcing rod 4. A column 66 is also fixedly connected to the body 1. The column 66 is slidably connected to the connecting sleeve 65. A limiting ring 67 is fixedly connected to the column 66. When the scraper 2 moves to the lower end of the cathode plate, the reinforcing rod 4 drives the connecting sleeve 65 to move through the connecting rod 64. At this time, the limiting ring 67 abuts against the connecting sleeve 65 to limit the reinforcing rod 4, thereby limiting the scraper 2 and reducing the probability that the lower end of the scraper 2 will be stuck in the conical slag hopper.
