Description
Technical Field
[0001] The utility model belongs to the technical field of storage devices, and particularly relates to a storage tank with an automatic cleaning function. Background Art
[0002] Some sticky materials are used in food processing plants, and these materials are delivered in small packaging barrels of 50 kg or 100 kg. During the food processing process, these sticky materials need to be used as raw materials and are temporarily stored in a storage tank. After the work is completed, the storage tank needs to be cleaned in time to prevent the sticky materials from sticking to the tank and affecting the next use. At present, most of the tank cleaning methods are manual cleaning, which is time-consuming and laborious, and the cleaning effect is difficult to guarantee. Content of the Utility Model
[0003] In view of the actual situation, the utility model provides a storage tank with an automatic cleaning function that is more practical. The utility model is provided with a tank cleaning component inside the storage tank, and when the tank needs to be cleaned, the tank cleaning component is placed into the tank to realize automatic cleaning of the tank body.
[0004] The technical solution provided by the utility model is: a storage tank with an automatic cleaning function, including a vertical cylindrical tank body. A tank cleaning component is arranged inside the tank body. The tank cleaning component includes a central shaft, a scraper mounting sleeve, a gear sleeve, a compression cap sleeve, a driving motor, a motor mounting sleeve, a driving gear and a scraper. The central shaft is coaxial with the tank body, and threads are processed on the outer side of the central shaft. The scraper mounting sleeve is threadedly connected to the central shaft. The gear sleeve and the compression cap sleeve are sleeved on the central shaft. The scraper mounting sleeve, the gear sleeve and the compression cap sleeve are fixedly connected to each other. The compression cap sleeve is located above the gear sleeve, and the scraper mounting sleeve is located below the gear sleeve. One end of the scraper is fixedly connected to the scraper mounting sleeve, and the other end of the scraper abuts against the inner wall of the tank body. The motor mounting sleeve is sleeved on the central shaft above the compression cap sleeve. Axial long grooves are also processed on the outer wall of the central shaft. There are at least two long grooves. Protruding strips are arranged inside the motor mounting sleeve. The number of protruding strips is the same as the number of long grooves. The protruding strips are located in the long grooves. The driving motor is directly or indirectly fixedly connected to the motor mounting sleeve. The driving gear is installed on the output shaft of the driving motor. The driving gear meshes with the gear sleeve. The outer diameter of the compression cap sleeve is larger than the outer diameter of the gear sleeve, so the compression cap sleeve limits the upper end face of the driving gear.
[0005] A further technical solution is as follows: A barrel tipping mechanism is provided outside the tank body. The barrel tipping mechanism includes a rocker arm, a fixed support plate, a movable support plate, a hydraulic cylinder A, and a hydraulic cylinder B. There are two rocker arms, which are symmetrically hinged on both sides of the outer wall of the tank body. The fixed support plate is fixedly connected between the two rocker arms. A notch for accommodating the movable support plate is dug in the center of the fixed support plate. The movable support plate is in clearance fit with the fixed support plate. The hydraulic cylinder A is connected between the tank body and the rocker arm. By the telescopic movement of the hydraulic cylinder A, the up-and-down swing of the rocker arm is realized. When the hydraulic cylinder A extends, it pushes the rocker arm to swing upward, thereby lifting and pouring the viscous material packaging barrel. The hydraulic cylinder B is connected between the fixed support plate and the movable support plate. By the telescopic movement of the hydraulic cylinder B, the movement of the movable support plate relative to the fixed support plate is realized.
[0006] A further technical solution is as follows: The storage tank with an automatic cleaning function further includes a shaft limiting plate, insertion blocks, and positioning blocks. There are at least two insertion blocks, and one end of each insertion block is respectively hinged to the upper end of the outer wall of the tank body. The shaft limiting plate is provided with holes for inserting the insertion blocks. The upper end of the central shaft is detachably inserted into the shaft limiting plate. After insertion, the central shaft cannot rotate relative to the shaft limiting plate. The positioning block is fixedly connected to the lower end of the central shaft. The lower end of the tank body is a conical bottom, and the lower end surface of the positioning block matches the conical surface at the lower end of the tank body.
[0007] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0008] 1. After the work of the present invention is completed, the tank can be cleaned by the later-inserted tank cleaning assembly, and the viscous raw materials in the tank can be automatically cleaned up, reducing the labor intensity of manpower and having a stable cleaning effect.

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present 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 only used to explain the present utility model and are not used to limit the present utility model.
[0020] Refer to Figures 1-8, which is a storage tank with an automatic cleaning function disclosed by the present utility model. Its structure includes a vertical cylindrical tank body 1. A detachable tank cleaning component is arranged inside the tank body 1. The tank cleaning component includes a central shaft 15, a scraper mounting sleeve 13, a gear sleeve 12, a compression cap sleeve 11, a driving motor 18, a motor mounting sleeve 10, a driving gear 17 and a scraper 16. The central shaft 15 is coaxial with the tank body 1. Threads are machined on the outer side of the central shaft 15. The scraper mounting sleeve 13 is threadedly connected to the central shaft 15. The gear sleeve 12 and the compression cap sleeve 11 are sleeved on the central shaft 15. The scraper mounting sleeve 13, the gear sleeve 12 and the compression cap sleeve 11 are fixedly connected and rotate together. The compression cap sleeve 11 is located above the gear sleeve 12, and the scraper mounting sleeve 13 is located below the gear sleeve 12. One end of the scraper 16 is fixedly connected to the scraper mounting sleeve 13, and the other end of the scraper 16 abuts against the inner wall of the tank body 1. When the scraper mounting sleeve 13 rotates, it drives the scraper 16 to rotate, and the scraper 16 scrapes off the viscous material on the inner wall of the tank body 1. The viscous material finally drops to the bottom of the tank and is discharged. The motor mounting sleeve 10 is sleeved on the central shaft 15 above the compression cap sleeve 11. Axial long grooves are also machined on the outer wall of the central shaft 15. There are at least two long grooves (in this embodiment, there are four long grooves). The inner side of the motor mounting sleeve 10 is provided with protruding strips 19. The number of protruding strips 19 is the same as the number of long grooves (in this embodiment, there are four protruding strips 19). The protruding strips 19 are located in the long grooves. In this way, the rotation of the motor mounting sleeve 10 relative to the central shaft 15 is restricted, and only the up and down sliding of the motor mounting sleeve 10 relative to the central shaft 15 is allowed. The driving motor 18 is directly or indirectly fixedly connected to the motor mounting sleeve 10. The driving gear 17 is installed on the output shaft of the driving motor 18. The driving gear 17 meshes with the gear sleeve 12, so as to drive the gear sleeve 12 and the scraper mounting sleeve 13 to rotate. The outer diameter of the compression cap sleeve 11 is larger than the outer diameter of the gear sleeve 12, so the compression cap sleeve 11 limits the upper end face of the driving gear 17. That is, when the scraper mounting sleeve 13 moves downward relative to the central shaft 15, under the limiting action of the compression cap sleeve 11, the driving gear 17, the driving motor 18 and the motor mounting sleeve 10 move downward together.
[0021] In order to fix the upper end of the central shaft 15 immobile, the storage tank with an automatic cleaning function further includes a shaft limiting plate 9, insertion blocks 8 and a positioning block 14. There are at least two insertion blocks 8. One end of each insertion block 8 is respectively hinged to the upper end of the outer wall of the tank body 1. The shaft limiting plate 9 is provided with holes for inserting the insertion blocks 8. After the insertion blocks 8 are inserted into the shaft limiting plate 9, the rotation of the shaft limiting plate 9 is restricted. The upper end of the central shaft 15 is detachably inserted into the shaft limiting plate 9. After being inserted, the central shaft 15 cannot rotate relative to the shaft limiting plate 9. The upper end of the central shaft 15 is processed into a polygon, such as a quadrilateral, a hexagon, etc. The shaft limiting plate 9 is processed with corresponding polygonal holes. After being inserted, the rotation of the central shaft 15 relative to the shaft limiting plate 9 is restricted. The positioning block 14 is fixedly connected to the lower end of the central shaft 15. The lower end of the tank body 1 is a conical bottom. The lower end surface of the positioning block 14 matches the conical surface at the lower end of the tank body 1.
[0022] In the prior art, there are two ways to pour viscous materials into a storage tank: one is manual barrel pouring, which consumes manpower; the other is pumping barrel pouring. Since viscous materials have high power requirements for pumps, the energy consumption is high during the pumping process, and viscous substances are likely to damage the pumps, so the pumping cost is relatively high. An inverted barrel mechanism is provided outside the tank body 1 of the present application. The inverted barrel mechanism includes a rocker arm 3, a fixed support plate 7, a movable support plate 6, a hydraulic cylinder A2 and a hydraulic cylinder B4. There are two rocker arms 3. The two rocker arms 3 are symmetrically hinged on both sides of the outer wall of the tank body 1. The fixed support plate 7 is fixedly connected between the two rocker arms 3. A notch for accommodating the movable support plate 6 is dug in the center of the fixed support plate 7. The movable support plate 6 is in clearance fit with the fixed support plate 7. The hydraulic cylinder A2 is connected between the tank body 1 and the rocker arm 3. By the telescopic movement of the hydraulic cylinder A2, the up and down swing of the rocker arm 3 is realized. When the hydraulic cylinder A2 extends, it pushes the rocker arm 3 to swing upward, thereby lifting and pouring the viscous material packaging barrel 5. The hydraulic cylinder B4 is connected between the fixed support plate 7 and the movable support plate 6. By the telescopic movement of the hydraulic cylinder B4, the movement of the movable support plate 6 relative to the fixed support plate 7 is realized. After the movable support plate 6 moves down to Figure 4 the position shown, it is closer to the ground, making it more convenient to place the viscous material packaging barrel 5 on the movable support plate 6. In summary, the present utility model has an inverted barrel function. The power component in the inverted barrel mechanism is a hydraulic cylinder, and the hydraulic cylinder is not easily damaged and has better economy.
[0023] The inverted barrel process of the present utility model is divided into two steps. The first step is from Figures 4-5 , the hydraulic cylinder B4 contracts to first lift the viscous material packaging barrel 5; the second step is from Figures 5-6 , the hydraulic cylinder A2 extends to pour the viscous material packaging barrel 5.
[0024] The utility model only needs to clean the tank after the work is completed. Install the tank cleaning component before cleaning the tank and remove the tank cleaning component after cleaning the tank. The process of cleaning the tank of the utility model is faster and more efficient.
