Description

Technical Field

[0001] This utility model relates to the field of material lifting technology, and more specifically, to a material lifting device for a building materials factory with screening function. Background Technology

[0002] In the building materials production sector, material hoisting devices are core equipment connecting raw material receiving and processing steps. Traditional building materials factories typically use belt conveyors, with one end located in the unloading area and the other in another designated area, to transfer externally transported raw materials such as ore to a designated height or area. However, due to the complex raw material supply channels, the ore actually received is mostly coarse material, generally exhibiting uneven particle size distribution, with large-diameter stones, lumps, and other impurities often mixed in. Existing hoisting devices can only transfer raw materials and cannot pre-process them, requiring an additional screening process for secondary screening of the ore before subsequent use. This traditional hoisting device has exposed problems of poor process integration in modern industrial settings in large-scale building materials production enterprises. Therefore, there is an urgent need for process innovation through equipment functional integration. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides a material lifting device for building material factories with screening function, which is used to solve the above problems.

[0004] This utility model is implemented as follows:

[0005] A material lifting device for a building materials factory with screening function includes a first conveyor belt, a fixed frame mounted on the front side above the first conveyor belt, a feeding conveyor hopper and a vibrating screening component respectively mounted on the top of the fixed frame, a second conveyor belt inside the feeding conveyor hopper, the second conveyor belt transporting the material to the top of the vibrating screening component, and a third conveyor belt mounted on the top of the first conveyor belt, the third conveyor belt being located below and behind the vibrating screening component.

[0006] Furthermore, the feeding conveyor hopper includes first side plates disposed on both sides of the second conveyor belt, and a hopper is also disposed on the top of the second conveyor belt, with the outer side of the hopper welded to the first side plates.

[0007] Furthermore, hinge seats are respectively provided on the outer side of the first side plate near the front and rear ends. A first support frame is provided at the bottom of the hinge seat near the front side, and a second support frame is provided at the bottom of the hinge seat near the rear side. The above support frames are fixedly installed on the top of the fixed frame.

[0008] Furthermore, the second support frame is higher than the first support frame.

[0009] Furthermore, the vibrating screening assembly includes a screen box, a vibration motor is provided on one side of the screen box, and two elastic connectors are provided on both sides of the screen box. The other end of the elastic connector is fixed to the fixed frame, so that the screen box and the fixed frame form an elastic connection relationship.

[0010] Furthermore, the screen box includes a first screen and a second screen arranged in parallel from top to bottom. Second side plates are provided on both sides of the two screens, and a stabilizing frame is provided in the middle of the two second side plates. A feed inlet is provided on the front side of the first screen, and a first discharge outlet and a second discharge outlet are provided on the rear side of the first screen and the second screen, respectively.

[0011] Furthermore, the mesh size of the first screen is larger than that of the second screen, and sand and gravel with a particle size of 4.5 mm or less can pass through both screens.

[0012] Furthermore, the elastic connector includes a right-angle fixing plate fixedly disposed on the side of the second side plate, a compression spring disposed at the bottom of the right-angle fixing plate, and a base plate disposed at the other end of the compression spring.

[0013] Furthermore, the elastic connector near the front has a column between its base plate and the fixing frame, and the elastic connector near the rear has its base plate fixedly mounted on the top of the fixing frame.

[0014] Furthermore, the feed inlet of the screen box is located below the rear end of the second conveyor belt, and the first discharge outlet and the second discharge outlet are located at the front edge of the third conveyor belt.

[0015] The beneficial effects of this invention are as follows: This device achieves raw material pretreatment through an integrated screening design. The mineral sand raw material is conveyed to the vibrating screening component via the second conveyor belt of the feed hopper. Under the vibration of the double-layer screen, sorting is completed. The first screen, through high-frequency vibration, can both break up raw material clumps and separate fine sand adhering to the surface of large-diameter particles. The lower screen further refines the filtration, ultimately allowing qualified fine sand to fall directly onto the bottom first conveyor belt and be transported to the main material area. Large-diameter materials that are retained are introduced into the third conveyor belt through two discharge ports, achieving automatic separation of coarse and fine materials. Compared to traditional lifting devices, this device pre-processes the material lifting process, reducing secondary processing steps, improving overall efficiency, effectively solving the technical bottleneck of the disconnect between lifting and screening in traditional processes, and enhancing the continuity of the building materials production system.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] like Figure 1 As shown, this utility model provides a material lifting device for a building materials factory with screening function, including a first conveyor belt 10. A fixed frame 11 is mounted on the front side above the first conveyor belt 10. A feeding conveyor hopper 20 and a vibrating screening component 30 are respectively arranged on the top of the fixed frame 11. The feeding conveyor hopper 20 has a second conveyor belt 21 inside, which transports the material to the top of the vibrating screening component 30. A third conveyor belt 40 is also arranged on the top of the first conveyor belt 10. The third conveyor belt 40 is located below the rear side of the vibrating screening component 30. The vibrating screening component 30 screens the raw materials during the transfer process, reducing the corresponding screening process and increasing efficiency in subsequent use.

[0025] like Figure 2 As shown, the feeding conveyor hopper 20 includes first side plates 22 arranged on both sides of the second conveyor belt 21. A hopper 24 is also arranged on the top of the second conveyor belt 21. The outer side of the hopper 24 is welded to the first side plate 22. A hinge seat 23 is arranged on the outer side of the first side plate 22 near the front and rear ends respectively. A first support frame 25 is arranged at the bottom of the hinge seat 23 near the front side, and a second support frame 26 is arranged at the bottom of the hinge seat 23 near the rear side. The above support frames are fixedly arranged on the top of the fixed frame 11.

[0026] The second support frame 26 is higher than the first support frame 25. The height difference between the two support frames is used to tilt the first transmission belt, which makes it easier to temporarily accumulate more raw materials in the feed conveyor hopper 20.

[0027] like Figure 3-4 As shown, the vibrating screening assembly 30 includes a screen box 31, a vibrating motor 33 is provided on one side of the screen box 31, and two elastic connectors 32 are provided on both sides of the screen box 31 respectively. The other end of the elastic connector 32 is fixed on the fixed frame 11, so that the screen box 31 and the fixed frame 11 form an elastic connection relationship.

[0028] The screen box 31 includes a first screen 3102 and a second screen 3103 arranged in parallel from top to bottom. Second side plates 3101 are provided on both sides of the two screens. A stabilizing frame 3104 is also provided in the middle of the two second side plates 3101. A feed inlet 3105 is provided on the front side of the first screen 3102. A first discharge outlet 3106 and a second discharge outlet 3107 are respectively provided on the rear side of the first screen 3102 and the second screen 3103.

[0029] It should be noted that the mesh size of the first screen 3102 is larger than that of the second screen 3103, and sand and gravel with a particle size of less than or equal to 4.5 mm can pass through both screens. The main function of the first screen 3102 is to use the vibration motor 33 to break up the clumps in the raw material during the vibration process, and at the same time separate fine sand from large particles. After the initial filtration by the first screen 3102, the second screen 3103 further separates the fine sand that meets the requirements for subsequent use, causing it to fall onto the first conveyor belt 10 at the bottom for direct transportation to the target area.

[0030] In this embodiment, the elastic connector 32 includes a right-angle fixing plate fixedly disposed on the side of the second side plate 3101, a compression spring disposed at the bottom of the right-angle fixing plate, and a base plate disposed at the other end of the compression spring.

[0031] Among them, the elastic connector 32 near the front has a column between its base plate and the fixed frame 11, and the elastic connector 32 near the rear has its base plate fixedly installed on the top of the fixed frame 11. That is, the height of the front side of the screen box 31 is increased by the column, so that it is tilted backward, which facilitates the movement and screening of raw materials.

[0032] In this embodiment, the feed inlet 3105 of the screen box 31 is located below the rear end of the second conveyor belt 21, and the first discharge outlet 3106 and the second discharge outlet 3107 are located at the front edge of the third conveyor belt 40.

[0033] Specifically, the working principle of this material lifting device for a building materials factory with screening function is as follows: Mineral sand is poured into the feed conveyor hopper 20. At this time, the second conveyor belt 21 transports the mineral sand in the hopper 24 to the vibrating screening component 30. After passing through two layers of screens, the large-diameter particles are filtered out, causing the fine sand to fall from the bottom of the screen box 31 onto the first conveyor belt 10. The fine sand is then transported to the target area via the first conveyor belt 10. Furthermore, the filtered large-diameter particles fall through two discharge ports onto the third conveyor belt 40, and are then transported to the corresponding area. This achieves the separation and filtration of mineral sand upon its entry into the storage area, solving the problem that existing lifting devices can only transfer raw materials and cannot pre-treat materials, resulting in poor integration with modern processes.

[0034] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
