Description

Technical Field

[0001] This invention relates to the field of engine raw material unloading, and more specifically, to a control method and apparatus for efficiently unloading new and old wet and dry sand particles. Background Technology

[0002] In the storage and unloading of granular and powdery materials (such as building materials, chemical raw materials, and grain processing), round filling hoppers are commonly used as material storage containers due to their simple structure, large capacity, and wide application in various production scenarios. However, existing round filling hoppers have several technical drawbacks in actual use, which seriously affect operational efficiency, unloading stability, and material utilization, as detailed below: First, materials are prone to clumping and accumulating due to gravity during long-term storage or feeding in the loading tank, especially on the inner wall and bottom corners, where material residue is easily formed. This not only wastes materials but may also cause deterioration and clumping of the residue, affecting the purity and effectiveness of subsequent materials. Most existing loading tanks do not have an effective material dispensing mechanism, or the dispensing mechanism has a simple structure that can only achieve simple stirring and cannot adhere to the tank wall for comprehensive cleaning. The dispensing effect is poor and it is easy to cause wear to the tank wall.

[0003] Secondly, the existing material feeding structure of the loading hopper is mostly a single unloading pipe, which cannot meet different unloading needs. When a small amount of material needs to be unloaded accurately, a single unloading pipe is difficult to control the unloading amount and is prone to over-unloading or leakage. When a large amount of material needs to be unloaded quickly, the unloading efficiency of a single unloading pipe is low and cannot adapt to the rhythm of continuous production. In addition, the control of the unloading electric valve is not convenient enough and the operation is cumbersome.

[0004] Furthermore, the existing transmission mechanism of the loading hopper is poorly designed, mostly using direct drive, which results in poor transmission stability. The motor is prone to vibration during operation, causing the loading hopper to shake, affecting the unloading accuracy and the overall service life of the device. At the same time, the installation and maintenance of the transmission structure are inconvenient, and the gears are not tightly meshed, which can easily lead to jamming, wear and other problems, increasing equipment maintenance costs and downtime.

[0005] In addition, the existing support structure of the loading hopper is mostly a single support method, which is not stable enough. When the material is full or the motor is running and vibrating, the device is prone to tilting or displacement, which poses a safety hazard. Moreover, the overall structural layout is unreasonable. The position design of components such as motor, support block, and unloading pipe lacks overall planning, resulting in narrow operating space and inconvenience for subsequent inspection and maintenance, which further reduces the continuity and convenience of production operations. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a control method and device for efficient unloading of new and old wet and dry sand particles, which addresses the shortcomings of the existing technology. This solves the technical problems of existing material storage and unloading devices, such as excessive material residue, single unloading method, unstable transmission, weak support, and inconvenient operation and maintenance.

[0007] The present invention discloses a control device for efficient unloading of new and old wet and dry sand particles. The device includes a circular loading bucket, a support base and a base. The circular material hopper is fixedly mounted on a support base. A second drive structure is provided between the circular material hopper and the support base. The support base is fixedly mounted on a base. A first drive structure is provided on the base. The first drive structure and the second drive structure are meshed together. A material feeding structure is provided on the second drive structure. A feeding pipe is provided above the circular material hopper. A first discharge pipe and a second discharge pipe are provided on one side of the circular material hopper. A first discharge electric valve is installed on the first discharge pipe. A second discharge electric valve is installed on the second discharge pipe. The first drive structure, the first discharge electric valve, and the second discharge electric valve are all electrically connected to a controller.

[0008] As a further improvement, a second support block and a third support block are also fixedly installed on the base, and the first drive structure includes a rotating disk, a belt, a second gear disk and a motor; A motor is mounted on the third support block, and a rotating disk is rotatably mounted on the second support block. The rotating disk is fixedly connected to the second gear disk, and the rotating disk is connected to the drive end of the motor via a belt drive. The motor is electrically connected to the controller.

[0009] Furthermore, the first drive structure is a first gear disk, the circular loading barrel is rotatably connected to the first gear disk, the first gear disk is rotatably connected to the support base, and the first gear disk and the second gear disk are meshed together.

[0010] Furthermore, the feeding structure includes a rotating shaft and a feeding rod. The rotating shaft is fixedly installed in the middle above the first gear disk. The rotating shaft passes through the inside of the circular feeding barrel. The feeding rod is fixedly installed on one side of the rotating shaft. The end of the feeding rod is provided with a buffer part.

[0011] Furthermore, the buffer section is made of polyurethane material.

[0012] Furthermore, a dust cover is fixedly installed between the second support block and the third support block.

[0013] Furthermore, the bottom of the support is fixedly mounted on the base by a plurality of first support blocks.

[0014] Furthermore, a flow sensor is installed on the inner wall of the feed pipe, and the flow sensor is electrically connected to the controller.

[0015] A method for using the aforementioned control device for efficient unloading of new and old wet-dry sand particles includes, When unloading is required, the power of the motor is set to the preset first power, the first unloading electric valve is opened, the second unloading electric valve is closed, and the sand is poured into the first feed pipe to start unloading. During the unloading process, a first flow threshold and a second flow threshold are set. The real-time flow rate of the material is obtained through the flow sensor. The real-time flow rate is compared with the first flow threshold and the second flow threshold respectively. When the real-time flow rate is less than or equal to the first flow threshold, the power of the motor is maintained at the first power, and the first unloading electric valve is kept open and the second unloading electric valve is kept closed. When the real-time flow rate is greater than the first flow threshold and less than or equal to the second flow threshold, the second power is calibrated according to the second flow threshold, and the power of the motor is increased from the first power to the second power, and the first unloading electric valve is kept open and the second unloading electric valve is kept closed. When the real-time flow rate is greater than the second flow threshold, the power of the motor is maintained at the second power, and the first unloading electric valve and the second unloading electric valve are opened simultaneously. When it is necessary to stop unloading, turn off the motor and close the first and second unloading electric valves.

[0016] Beneficial effects The advantages of this invention are: 1. This invention uses a motor-driven belt drive to rotate a rotating disk and a second gear disk. The meshing connection between the second gear and the first gear drives the first gear disk and the rotating shaft to rotate synchronously, thereby causing the feeding rod to rotate within the circular filling hopper. The feeding rod has a buffer section at its end that matches the inner wall of the filling hopper. This buffer section not only allows for thorough feeding by conforming to the hopper wall, completely scraping and loosening material from the inner wall and bottom corners of the hopper, preventing material clumping and residue, but also reduces wear on the hopper wall, extending the hopper's service life. Simultaneously, the rotation of the feeding rod also uniformly stirs the material inside the hopper, ensuring even mixing and improving the subsequent use of the material. This effectively solves the problems of excessive material residue and significant waste in existing devices.

[0017] 2. This invention utilizes a method for efficiently controlling the unloading of both new and old wet / dry sand particles. It allows for flexible control of the first and second unloading electric valves and the motor based on actual unloading needs, preventing overloading or leakage, significantly improving unloading efficiency, and adapting to continuous production schedules. The independent control design of the dual unloading valves is convenient and flexible, overcoming the limitation of existing devices with a single unloading port that cannot adapt to different unloading requirements, thus enhancing operational flexibility and applicability.

Detailed Implementation

[0020] The present invention will be further described below with reference to embodiments, but this does not constitute any limitation on the present invention. Any limited modifications made by any person within the scope of the claims of the present invention are still within the scope of the claims of the present invention. See Figures 1-3 The present invention provides a control device for efficient unloading of new and old wet and dry sand particles. The device includes a circular loading hopper 9, a support base 17 and a base 1.

[0021] A circular material hopper 9 is fixedly installed on a support base 17. A second drive structure is provided between the circular material hopper 9 and the support base 17. The support base 17 is fixedly installed on a base 1. A first drive structure is provided on the base 1. The first drive structure and the second drive structure are meshed together. A material feeding structure is provided on the second drive structure. A feeding pipe 12 is provided above the circular material hopper 9. A first unloading pipe 10 and a second unloading pipe 15 are provided on one side of the circular material hopper 9. A first unloading electric valve 11 is installed on the first unloading pipe 10. A second unloading electric valve 16 is installed on the second unloading pipe 15. The first drive structure, the first unloading electric valve 11 and the second unloading electric valve 16 are all electrically connected to the controller.

[0022] The round filling hopper 9 is made of high-quality low-alloy steel, which is machined after normalizing heat treatment. It has good integrity, is not easy to deform, has high precision, and uses wear-resistant liners.

[0023] like Figure 2 As shown, a second support block 3 and a third support block 4 are also fixedly installed on the base 1. The first drive structure includes a rotating disk 18, a belt 19, a second gear disk 20, and a motor 5. The motor 5 is installed on the third support block 4, and the rotating disk 18 is rotatably installed on the second support block 3. The rotating disk 18 is fixedly connected to the second gear disk 20, and the rotating disk 18 is connected to the drive end of the motor 5 via the belt 19. The motor 5 is electrically connected to the controller. The motor 5 uses a hardened gear reducer manufactured by SEW.

[0024] The first drive structure is a first gear disk 7, a circular loading barrel 9 is rotatably connected to the first gear disk 7, the first gear disk 7 is rotatably connected to the support base 17, and the first gear disk 7 and the second gear disk 20 are meshed together.

[0025] The first gear disk 7 has multiple first teeth 8, and the second gear disk 20 has multiple second teeth 21.

[0026] like Figure 3 As shown, the feeding structure includes a rotating shaft 13 and a feeding rod 14. The rotating shaft 13 is fixedly installed in the middle above the first gear disk 7. The rotating shaft 13 passes through the interior of the circular feeding barrel 9. The feeding rod 14 is fixedly installed on one side of the rotating shaft 13. The end of the feeding rod 14 is provided with a buffer part. The buffer part is made of polyurethane material.

[0027] By starting the motor 5, the drive end of the motor 5 rotates, and the drive end of the motor 5 drives the rotating disk 18 to rotate through the belt 19, which in turn drives the second gear disk 20 to rotate. Then the second gear disk 20 drives the first gear disk 7 to rotate, and the feeding rod 14 on the first gear disk 7 rotates to perform feeding work.

[0028] The bottom of the support base 17 is fixedly mounted on the base 1 by multiple first support blocks 2.

[0029] A dust cover 6 is fixedly installed between the second support block 3 and the third support block 4. The dust cover 6 is used to protect the belt 19 from dust.

[0030] A flow sensor is installed on the inner wall of the feed pipe 12. In this embodiment, the flow sensor is a Dens Flow HP dense phase transport flow sensor. The flow sensor is electrically connected to the controller.

[0031] A method for using the aforementioned control device for efficient unloading of new and old wet-dry sand particles includes, When unloading is required, set the power of motor 5 to the preset first power, open the first unloading electric valve 11, close the second unloading electric valve 16, and pour the sand into the first feed pipe 12 to begin unloading. Avoid over-unloading or leakage.

[0032] During the unloading process, a first flow rate threshold and a second flow rate threshold are set. The real-time flow rate of the material is acquired through a flow sensor and compared with the first and second flow rate thresholds respectively. When the real-time flow rate is less than or equal to the first flow rate threshold, the power of motor 5 is maintained at the first power, and the first unloading electric valve 11 remains open while the second unloading electric valve 16 remains closed. When the real-time flow rate is greater than the first flow rate threshold but less than or equal to the second flow rate threshold, the second power is calibrated according to the second flow rate threshold, and the power of motor 5 is increased from the first power to the second power, while the first unloading electric valve 11 remains open and the second unloading electric valve 16 remains closed. When the real-time flow rate is greater than the second flow rate threshold, the power of motor 5 is maintained at the second power, and both the first and second unloading electric valves 11 and 16 are opened simultaneously. This significantly improves unloading efficiency and adapts to the rhythm of continuous production.

[0033] When it is necessary to stop unloading, turn off motor 5 and close the first unloading electric valve 11 and the second unloading electric valve 16. The independent control design of the dual unloading valves makes operation convenient and flexible, solving the problem that the single unloading port of the existing device cannot adapt to different unloading needs, and improving the flexibility and applicability of the operation.

[0034] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of the present invention, and these will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
