Description

Technical Field

[0001] This application relates to the field of water and fertilizer machine storage tank technology, specifically a corrosion-resistant water and fertilizer machine storage tank device. Background Technology

[0002] The liquid storage tank of the fertigation machine is a container used to store liquid water-soluble fertilizer in fertigation equipment. It is generally a vertical or horizontal structure. As an important piece of equipment for storing and transporting liquid water-soluble fertilizer, the tank capacity can be configured according to the production capacity requirements of the manufacturer.

[0003] During long-term use of the water-soluble fertilizer storage tank, impurities in the water-soluble fertilizer can easily adhere to the inner wall of the storage tank (the impurities are mainly substances such as calcium sulfate). These impurities accumulate over time and form a scale layer. Under the influence of its own weight and external vibration, the scale layer may collapse locally, which may cause defects in the inner wall of the tank and thus lead to corrosion. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and to propose a corrosion-resistant water and fertilizer machine storage tank device to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides a corrosion-resistant water and fertilizer machine storage tank device, including a base, on which a storage tank is fixedly installed. A tank top is fixedly connected to the top of the storage tank, and a cover is detachably installed on the top of the tank top via a locking mechanism. A hydraulic cylinder is fixedly installed on the base, and a hydraulic rod is fixedly connected to the output end of the hydraulic cylinder. A support platform is fixedly connected to the top end of the hydraulic rod, and a scraping mechanism and a driving mechanism are provided on the support platform.

[0006] Preferably, the locking mechanism includes a fixing plate fixedly connected to the outer surface of the liquid storage tank, an inner through shaft fixedly inserted on the inner side of the fixing plate, a screw rotatably connected to the outer surface of the inner through shaft, and a nut threaded onto the outer surface of the screw. The locking mechanism allows for flexible assembly and disassembly of the cover.

[0007] Preferably, the scraping mechanism includes an internal toothed sleeve rotatably connected to the bottom of the support platform. A concave plate is fixedly connected to the outer surface of the internal toothed sleeve, and a connecting rod is rotatably connected to the inner surface of the concave plate. A scraper is provided at the bottom end of the connecting rod. The scraping mechanism enables the scraper to scrape along the inner wall of the liquid storage tank under the action of the driving mechanism.

[0008] Preferably, the driving mechanism includes a motor fixedly mounted on a support platform, a drive wheel fixedly connected to the output end of the motor, and a conveyor belt slidably connected to the outer surface of the drive wheel. Through the driving mechanism, two sets of scrapers can be made to rotate while scraping the inner wall of the liquid storage tank in a circular motion.

[0009] Preferably, the inner surface of the support platform is rotatably connected to a rotating shaft, the top of the rotating shaft is fixedly connected to a transmission wheel, and the outer surface of the transmission wheel is slidably connected to the inner side of the conveyor belt away from the drive wheel.

[0010] Preferably, a main gear is fixedly connected to the bottom end of the rotating shaft, and a secondary gear is fixedly connected to the top of the connecting rod. The outer surface of the secondary gear meshes with the outer surface of the main gear, and the outer surface of the secondary gear meshes with the inner side of the internal gear sleeve.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This corrosion-resistant septic tank device, through a drive mechanism and a scraping mechanism, allows the scraper to rotate on its own axis while revolving around the central axis. The synergistic effect of the central and rotational axes enables the scraper to perform three-dimensional dynamic cleaning on the inner wall of the storage tank. The rotational axis generates local rotational friction, covering more surface details, such as tiny protrusions or depressions. Combined with the shearing force generated by the central axis, it can effectively break the bonding force between the scale layer and the tank wall.

[0012] 2. This corrosion-resistant septic tank device, through the design of hydraulic cylinder and hydraulic rod, can flexibly adjust the position of the scraper. During the storage of solution in the tank, the scraper can be moved up to a height that will not obstruct the opening of the cover, making it easy to flexibly install and remove the cover through the fastening mechanism. During the cleaning process, the scraper can be moved down to a position that is completely in contact with the inner wall of the tank, ensuring the cleaning effect. Attached Figure Description

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0016] Please see Figure 1-3 A corrosion-resistant slurry storage tank device includes a base 1, a storage tank 2 fixedly installed on the base 1, a tank top 3 fixedly connected to the top of the storage tank 2, and a detachable cover 4 installed on the top of the tank top 3 via a locking mechanism. Both the tank top 3 and the cover 4 have grooves near the screw 7 to better secure the cover 4 to the tank top 3. A hydraulic cylinder 9 is fixedly installed on the base 1, and a hydraulic rod 10 is fixedly connected to the output end of the hydraulic cylinder 9. A support platform 11 is fixedly connected to the top end of the hydraulic rod 10. A scraping mechanism and a driving mechanism are provided on the support platform 11.

[0017] Through the above technical solution, during the use of the device, the scraper 15 is first moved to the top of the storage tank 2 by the hydraulic cylinder 9 and the hydraulic rod 10. When the storage tank 2 stores the solution, the clamping mechanism is used to make the cover 4 stably installed on the top of the tank 3 to seal the storage tank 2. After the solution is discharged, the two sets of scrapers 15 can be rotated and scraped along the inner wall of the storage tank 2 by the drive mechanism and the scraping mechanism to remove the impurities attached to the inner wall of the storage tank 2.

[0018] Specifically, the locking mechanism includes a fixing plate 5 fixedly connected to the outer surface of the liquid storage tank 2, an inner through shaft 6 fixedly inserted on the inner side of the fixing plate 5, a screw 7 rotatably connected to the outer surface of the inner through shaft 6, and a nut 8 threadedly fitted on the outer surface of the screw 7.

[0019] With the above technical solution, since both the can top 3 and the cover 4 have grooves near the screw 7, the screw 7 can be embedded into the corresponding grooves during the rotation of the screw 7 along the inner through shaft 6.

[0020] Specifically, the scraping mechanism includes an internal toothed sleeve 12 rotatably connected to the bottom of the support platform 11. A concave plate 13 is fixedly connected to the outer surface of the internal toothed sleeve 12. A connecting rod 14 is rotatably connected to the inner surface of the concave plate 13. A scraper 15 is provided at the bottom end of the connecting rod 14.

[0021] Through the above technical solution, the connecting rod 14 is designed with two sets, and the corresponding scraper 15 is also designed with two sets. The two sets of scrapers 15 are evenly distributed around the rotating shaft 20, and the internal toothed sleeve 12 and the concave plate 13 rotate synchronously.

[0022] Specifically, the drive mechanism includes a motor 16 fixedly mounted on the support platform 11, a drive wheel 17 fixedly connected to the output end of the motor 16, and a conveyor belt 18 slidably connected to the outer surface of the drive wheel 17.

[0023] Through the above technical solution, in the transmission system composed of drive wheel 17, conveyor belt 18 and transmission wheel 19, the transmission wrap angle is greater than 120 degrees.

[0024] Specifically, a rotating shaft 20 is rotatably connected to the inner surface of the support platform 11, a transmission wheel 19 is fixedly connected to the top of the rotating shaft 20, and the outer surface of the transmission wheel 19 is slidably connected to the inner side of the conveyor belt 18 away from the drive wheel 17.

[0025] Through the above technical solution, the transmission function of the conveyor belt 18 is to convert the rotation of the drive wheel 17 into the rotation of the transmission wheel 19. During this process, the transmission wheel 19 will drive the rotating shaft 20 to rotate, which will eventually drive the main gear 21 to rotate.

[0026] Specifically, the bottom end of the rotating shaft 20 is fixedly connected to the main gear 21, and the top of the connecting rod 14 is fixedly connected to the auxiliary gear 22. The outer surface of the auxiliary gear 22 meshes with the outer surface of the main gear 21, and the outer surface of the auxiliary gear 22 meshes with the inner side of the internal gear sleeve 12.

[0027] Through the above technical solution, the main gear 21 at the bottom of the rotating shaft 20 is designed to have one set, while the auxiliary gear 22 connected to the connecting rod 14 is provided with two sets. During the rotation of the main gear 21, it will synchronously drive the two sets of auxiliary gears 22 that mesh with it to rotate synchronously.

[0028] Working Principle: During operation, while the solution is stored in the storage tank 2, the hydraulic cylinder 9 and hydraulic rod 10 can raise the support platform 11, allowing the scraper 15 to move to a height that does not obstruct the opening of the cover 4. During this process, the cover 4 needs to be positioned appropriately on the tank top 3 (the grooves on their surfaces should overlap). Then, the screw 7 is turned along the inner shaft 6 until it is vertical. Next, the nut 8 is tightened to move it axially along the screw 7. During this process, the nut 8 gradually moves downwards until it firmly abuts against the cover 4, providing a stable and limiting effect. This ensures the cover 4 is securely installed on the tank top 3, providing a sealing function. After all the solution in the storage tank 2 has been drained, the cover 4 needs to be opened, and the scraper 15 is lowered to a position completely against the inner wall of the storage tank 2. Then, the motor 16 is turned on to drive the drive wheel 17. During this process, the conveyor belt 18... When in use, the transmission wheel 19 is driven to rotate synchronously, that is, the main gear 21 rotates synchronously through the rotating shaft 20. During the rotation of the main gear 21, it drives the two sets of auxiliary gears 22 that mesh with it to rotate as well. Therefore, the scraper 15 connected to the auxiliary gear 22 through the connecting rod 14 will also rotate. At the same time, during the rotation of the auxiliary gear 22, it will drive the internal gear sleeve 12 that meshes with it to rotate. That is, the concave plate 13 on the internal gear sleeve 12 will drive the two sets of connecting rods 14 and the scraper 15 to revolve around the rotating shaft 20. Therefore, the effect is that the two sets of scrapers 15 revolve around the inner wall of the storage tank 2 while rotating on their own axis. The rotation causes the scraper 15 to generate local rotational friction on the revolving trajectory, covering more surface details (such as small protrusions or depressions). Combined with the shearing force generated by the revolving axis, it can break the bonding force between the scale layer and the tank wall, which is especially suitable for hard scale layers (such as calcium sulfate crystals), thereby effectively reducing the corrosion of the inner wall of the water fertilizer machine storage tank 2.
