Description

Technical Field

[0001] This utility model relates to the field of screening machine technology, specifically a fluidized solidified soil screening machine. Background Technology

[0002] In the fields of civil engineering, environmental management and resource recycling, fluidized solidified soil is widely used in foundation treatment, river restoration and waste soil reuse projects due to its good plasticity, high strength and environmental protection characteristics. However, in the preparation and application of fluidized solidified soil, the purity of raw materials directly affects its final performance. Therefore, soil screening, as a key pre-process, places extremely high demands on the efficiency, accuracy and reliability of screening equipment.

[0003] Existing soil screening machines mostly adopt a single inlet and outlet design. If the material is continuously fed during the removal of impurities, the new and old materials will be mixed, reducing the purity of the discharged impurities. Therefore, it is necessary to design a fluidized solidified soil screening machine to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a fluidized solidified soil screening machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fluidized solidified soil screening machine, comprising a filter basket, wherein the top and bottom of the filter basket are provided with staggered through holes for feeding and discharging impurities respectively; the filter basket is provided with a sealing component, which can asynchronously close the top and bottom through holes, so that the bottom through hole is closed when the top through hole is open, and the top through hole is closed when the bottom through hole is open.

[0006] Preferably, the sealing component includes a rotating rod and baffles. A set of baffles is installed on the outside of the rotating rod corresponding to the top and bottom through holes, and the two sets of baffles are arranged in the same direction. The rotating rod is rotatably connected to the top of the filter basket and can be rotated by the first drive assembly.

[0007] Preferably, the first drive assembly includes a first motor and a battery. The top end of the rotating rod is connected to the output end of the first motor. The first motor can be powered by the battery, which is installed on the top of the filter basket.

[0008] Preferably, the filter basket can be rotated by a second drive assembly, which includes a filter cylinder, an external gear ring, a gear, and a second motor. The upper end of the filter basket is rotatably connected to the upper end of the filter cylinder. A set of external gear rings is integrally formed on the top of the filter basket. The external gear rings mesh with the gear, and the gear is connected to the output end of the second motor.

[0009] Preferably, the lower end of the filter cartridge is connected to a set of collection boxes for receiving materials via a pull-out mechanism.

[0010] Preferably, a set of handles is installed on one side of the collection box.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Compared with the prior art, this utility model avoids the mixing of new and old materials. During the feeding stage, the bottom through hole is closed, so that no screened materials or impurities will be mixed into the newly entering materials. During the impurity discharge stage, the top through hole is closed to prevent new materials from entering and affecting the purity of the discharged impurities. By controlling the asynchronous opening and closing of the top and bottom through holes by the sealing component, the screening and impurity discharge processes are carried out in an orderly manner, which improves the screening efficiency. In addition, the structure design is relatively simple and easy to implement and maintain.

[0013] 2. This utility model, through the cooperation of the rotating rod and two sets of unidirectional baffles, can accurately achieve asynchronous sealing of the top and bottom through holes, ensuring that the feeding and impurity discharge processes do not interfere with each other. It continues the advantages of the overall screening machine in avoiding the mixing of new and old materials and improving the purity of impurity discharge. The first drive component adopts a combination of the first motor and the battery, so that the screening machine does not need to rely on complex external power supply lines, increasing the flexibility and convenience of equipment use and making it easy to use in different locations. Furthermore, the rotating rod and the top of the filter basket are connected in a rotating manner, as well as the installation structure of the baffles. The overall structure is simple, reducing the manufacturing cost and maintenance difficulty of the equipment. In the event of a failure, it is easy to inspect and replace the rotating rod, baffles, first motor and other components.

[0014] 3. The rotatable design of the filter basket in this utility model allows for more thorough contact between the fluidized solidified soil and the filter screen through centrifugal force, accelerating the screening speed and improving screening efficiency. Compared with traditional static screening, it can process more material in a shorter time. The meshing transmission method of the external gear ring and gears ensures stable and reliable transmission, guaranteeing the smooth rotation of the filter basket, reducing equipment failures caused by unstable transmission, and extending the service life of the equipment.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please refer to Figure 1-4 As shown, this utility model provides a fluidized solidified soil screening machine, including a filter basket 1. The top and bottom of the filter basket 1 are staggered with through holes 2 for feeding and discharging impurities, respectively. The filter basket 1 is provided with a sealing component, which can asynchronously close the top and bottom through holes 2, so that when the top through hole 2 is open, the bottom through hole 2 is closed, and when the bottom through hole 2 is open, the top through hole 2 is closed.

[0023] When the fluidized solidified soil enters through the through hole 2 at the top of the filter basket 1, the material will temporarily stay in the filter basket 1 because the sealing component closes the bottom through hole 2. In the filter basket 1, impurities in the soil are intercepted by the filter screen, while the fluidized solidified soil that meets the requirements continues to flow through the filter basket 1. When it is necessary to discharge impurities, the sealing component is operated to close the top through hole 2 and open the bottom through hole 2 at the same time. At this time, the impurities intercepted in the filter basket 1 are discharged from the bottom through hole 2.

[0024] Compared to existing technologies, this method avoids the mixing of new and old materials. During the feeding stage, the bottom through-hole 2 is closed, preventing screened materials or impurities from mixing into the newly entering material. During the impurity discharge stage, the top through-hole 2 is closed to prevent new materials from entering and affecting the purity of the discharged impurities. By controlling the asynchronous opening and closing of the top and bottom through-holes 2 by the sealing components, the screening and impurity discharge processes are carried out in an orderly manner, improving screening efficiency. In addition, the structure is relatively simple in design and easy to implement and maintain.

[0025] Specifically, the sealing component includes a rotating rod 3 and baffles 4. A set of baffles 4 is installed on the outside of the rotating rod 3 corresponding to the top and bottom through holes 2. The two sets of baffles 4 are arranged in the same direction. The rotating rod 3 is rotatably connected to the top of the filter basket 1 and can be rotated through the first drive assembly. The first drive assembly includes a first motor 5 and a battery 6. The top of the rotating rod 3 is connected to the output end of the first motor 5. The first motor 5 can be powered by the battery 6, which is installed on the top of the filter basket 1.

[0026] The first motor 5 is powered by the storage battery 6 and drives the connected rotating rod 3 to rotate. Since two sets of baffles 4 are installed on the outside of the rotating rod 3 corresponding to the top and bottom through holes 2, when the rotating rod 3 rotates, the two sets of baffles 4 rotate accordingly. During feeding, the rotating rod 3 drives the baffles 4 to rotate to close the bottom through hole 2, while the top through hole 2 is open. The fluidized solidified soil enters the filter basket 1 through the top through hole 2 for screening. When it is necessary to discharge impurities, the first motor 5 drives the rotating rod 3 to rotate again, so that the baffles 4 close the top through hole 2 and open the bottom through hole 2 at the same time, and the impurities are discharged from the bottom through hole 2.

[0027] Through the cooperation of the rotating rod 3 and the two sets of unidirectional baffles 4, the asynchronous sealing of the top and bottom through holes 2 can be precisely achieved, ensuring that the feeding and impurity discharge processes do not interfere with each other. This continues the advantages of the overall screening machine in avoiding the mixing of new and old materials and improving the purity of impurity discharge. The first drive component adopts a combination of the first motor 5 and the battery 6, so that the screening machine does not need to rely on complex external power supply lines, increasing the flexibility and convenience of equipment use and making it easy to use in different locations. Furthermore, the rotating rod 3 and the top of the filter basket 1 are connected in a rotating manner, and the installation structure of the baffles 4 are simple in overall construction, reducing the manufacturing cost and maintenance difficulty of the equipment. In the event of a failure in the future, it is convenient to inspect and replace components such as the rotating rod 3, the baffles 4, and the first motor 5.

[0028] The filter basket 1 can be rotated by the second drive assembly, which includes a filter cylinder 7, an external gear ring 8, a gear 9, and a second motor 10. The upper end of the filter basket 1 is rotatably connected to the upper end of the filter cylinder 7. A set of external gear rings 8 are integrally formed on the top of the filter basket 1. The external gear rings 8 mesh with the gear 9. The gear 9 is connected to the output end of the second motor 10. A set of collection boxes 11 for receiving materials is pulled out at the lower end of the filter cylinder 7. A set of handles 12 is installed on one side of the collection box 11.

[0029] After the second motor 10 starts, it drives the gear 9 connected to its output end to rotate. Since the gear 9 meshes with the outer gear ring 8 integrally formed at the top of the filter basket 1, the rotation of the gear 9 will drive the outer gear ring 8, which in turn drives the filter basket 1 to rotate. During the rotation of the filter basket 1, the fluidized solidified soil inside comes into full contact with the filter screen under the action of centrifugal force, etc., and the impurities in the soil are intercepted. The qualified material passes through the filter screen and falls into the filter cylinder 7 below, and finally enters the collection box 11 that is pulled out and connected to the lower end of the filter cylinder 7. When the collection box 11 is full of material, the operator can pull it out through the handle 12 to unload the material.

[0030] The rotatable design of the filter basket 1 allows for more thorough contact between the fluidized solidified soil and the filter screen through centrifugal force, accelerating the screening speed and improving screening efficiency. Compared to traditional static screening, it can process more material in a shorter time. The meshing transmission between the external gear ring 8 and the gear 9 ensures stable and reliable transmission, guaranteeing the smooth rotation of the filter basket 1, reducing equipment failures caused by unstable transmission, and extending the service life of the equipment. The collection box 11 is pulled out and connected to the lower end of the filter cylinder 7 and is equipped with a handle 12. This design facilitates quick and convenient unloading operations for operators, reducing labor intensity and also making it easy to clean and maintain the collection box 11. Fourthly, the filter cylinder 7 can initially receive and guide the screened material, preventing the material from scattering everywhere, keeping the working environment clean, and also helping to improve the integrity of material collection. Different collection operations can be performed by changing different collection boxes 11.

[0031] Working principle: The first motor 5 is powered by the battery 6 and drives the connected rotating rod 3 to rotate. Since two sets of baffles 4 are installed on the outside of the rotating rod 3 corresponding to the top and bottom through holes 2, when the rotating rod 3 rotates, the two sets of baffles 4 rotate accordingly. During feeding, the rotating rod 3 drives the baffles 4 to rotate until the bottom through hole 2 is closed, while the top through hole 2 is open. The fluidized solidified soil enters the filter basket 1 through the top through hole 2 for screening. When it is necessary to discharge impurities, the first motor 5 drives the rotating rod 3 to rotate again, causing the baffles 4 to close the top through hole 2 and simultaneously open the bottom through hole 2, allowing impurities to be discharged from the bottom through hole 2. After the second motor 10 starts, it drives... The gear 9 connected to its output end rotates. Since the gear 9 meshes with the outer gear ring 8 integrally formed at the top of the filter basket 1, the rotation of the gear 9 will drive the outer gear ring 8, which in turn will drive the filter basket 1 to rotate. During the rotation of the filter basket 1, the fluidized solidified soil inside will come into full contact with the filter screen under the action of centrifugal force, etc., and the impurities in the soil will be intercepted. The qualified material will pass through the filter screen and fall into the filter cylinder 7 below, and finally enter the collection box 11 that is pulled out and connected to the lower end of the filter cylinder 7. When the collection box 11 is full of material, the operator can pull it out through the handle 12 to unload the material. Different collection work can be carried out by changing different collection boxes 11.
