Description

Technical Field

[0001] This utility model relates to the technical field of sorting vibrating screen equipment, and in particular to a dual-channel large-scale sorting vibrating screen. Background Technology

[0002] Vibrating screens are commonly used equipment in the field of material sorting. They use a vibration source to cause the screen box to vibrate, which causes materials of different particle sizes to be separated through the screen. In practical applications, existing sorting vibrating screens often fail to achieve automatic and balanced distribution of material flow into different screening channels. This can easily lead to overload in one channel and underutilization of other channels, affecting the overall screening efficiency and processing capacity. Furthermore, after the material passes through the main screen, some fine particles may still adhere to the surface of larger particles and be discharged along with them, resulting in low purity of the final sorted material and incomplete separation.

[0003] Therefore, this application provides a dual-channel large-scale sorting vibrating screen to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide a dual-channel large-scale sorting vibrating screen, which aims to solve the problem that in the practical application of existing sorting vibrating screens, it is often difficult to achieve automatic and balanced distribution of material flow into different screening channels, which can easily lead to overload of one channel and insufficient utilization of other channels, affecting the overall screening efficiency and processing capacity. In addition, after the material passes through the main screen, some fine particles may still adhere to the surface of larger particles and be discharged together, resulting in low purity of the final sorted material and incomplete separation.

[0005] To achieve the above objectives, this application provides the following technical solution: a dual-channel large-scale sorting vibrating screen, comprising a vibrating screen body, the vibrating screen body further comprising a screen box, a feeding assembly and a discharging assembly, the feeding assembly and the discharging assembly being respectively connected to the front and rear ends of the screen box, the feeding assembly and the discharging assembly being detachably connected to the screen box, a vibration source being connected to the top of the screen box, and a support being provided below the screen box, the support being provided in four sets in a matrix below the screen box, the support being connected to a connecting block by a spring, the connecting block being installed on the side wall of the screen box;

[0006] The screen box is equipped with two sets of screens for sorting materials. The two sets of screens divide the interior of the screen box into an upper channel, a lower channel, and a finished product channel. The lower channel is located between the upper channel and the finished product channel. The two sets of screens are respectively connected to a material distribution component and a feed hopper. The material distribution component is located above the feed hopper. Through the material distribution component and the secondary filtration structure at the discharge end, automatic and balanced distribution of materials and efficient and fine screening are achieved, thereby improving the processing capacity and sorting accuracy of the large vibrating screen.

[0007] Preferably, the material distribution assembly further includes a material distribution plate and a connecting shaft. The material distribution plate is hinged to the screen box via the connecting shaft. A stop bar is provided above the material distribution plate, and a counterweight is connected to the bottom surface of the material distribution plate. Multiple sets of stop bars are provided. A torsion spring is provided at the connection between the connecting shaft and the screen box. Through the coordinated action of the material distribution plate, the counterweight, and the torsion spring, the automatic sensing and switching of the amount of material entering the upper and lower channels is realized, ensuring the load balance between the channels.

[0008] Preferably, the inlet size of the feed hopper is adapted to the material distribution plate, and the feed hopper is provided with a groove adapted to the counterweight, which ensures the structural compatibility between the material distribution plate and the feed hopper when the material distribution plate is flipped and reset, and ensures the smooth material distribution action.

[0009] Preferably, the feeding assembly further includes a feeding port and a side frame. The feeding port is connected to the top of the side frame, and a positioning plate is connected inside the side frame. The positioning plate is adapted to the position and size of the finished product channel. The positioning plate is located below the material distribution assembly. By blocking the material, the feeding material is effectively prevented from falling directly into the finished product channel without screening, ensuring that the material must go through the screening process.

[0010] Preferably, the discharge assembly further includes an upper discharge channel, a lower discharge channel, and a finished product discharge channel, and each of the upper discharge channel, the lower discharge channel, and the finished product discharge channel is connected to a discharge port.

[0011] Preferably, a second filter hole is provided at the connection between the upper discharge channel and the lower discharge channel, penetrating both the upper and lower discharge channels. A first filter hole is provided at the connection between the lower discharge channel and the finished product discharge channel, penetrating both the lower discharge channel and the finished product discharge channel. By utilizing the structure of the discharge channel to add filter holes, the remaining material to be discharged is subjected to final screening, further removing any fine particles that may adhere.

[0012] Preferably, both the first and second filter holes are provided in multiple sets, and the apertures of the first and second filter holes are the same as the apertures on the screen. The design of multiple sets of filter holes with matching apertures increases the area and efficiency of secondary filtration, effectively improving the purity of the final sieve residue.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] In this invention, by setting up a material distribution assembly with a distribution plate, counterweight, stop bar and torsion spring, the flow direction of material entering the upper and lower channels can be automatically adjusted according to the feed rate, realizing automatic balanced adjustment of feeding into the two screening channels, avoiding the problem of overload or underutilization of a single channel, and improving the overall processing capacity and screening efficiency of the equipment.

[0015] In this invention, by opening a second filter hole and a first filter hole in the upper discharge channel and the lower discharge channel respectively, a final screening opportunity is provided for the larger particles that are about to be discharged. This allows the fine particles adhering to the surface of these materials to be further separated and fall into the finished product channel and then into the finished product discharge channel, effectively improving the purity of the final sorted material.

[0023] 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. Example

[0024] refer to Figure 1-5 The large dual-channel sorting vibrating screen shown includes a vibrating screen body 1, which also includes a screen box 2, a feeding assembly 3, and a discharging assembly 4. The feeding assembly 3 and the discharging assembly 4 are respectively connected to the front and rear ends of the screen box 2. The feeding assembly 3 and the discharging assembly 4 are detachably connected to the screen box 2. The top of the screen box 2 is connected to an excitation source 5. The bottom of the screen box 2 is provided with a support 6. The support 6 is provided in a matrix of four sets below the screen box 2. The support 6 is connected to a connecting block 7 by a spring 8. The connecting block 7 is installed on the side wall of the screen box 2.

[0025] As one implementation method in this embodiment, to prevent all material from entering the upper channel 11 after input, the screen box 2 is equipped with two sets of screens for sorting materials. These two sets of screens divide the interior of the screen box 2 into an upper channel 11, a lower channel, and a finished product channel 12. The lower channel is located between the upper channel 11 and the finished product channel 12. A material distribution component 9 and a feed hopper 10 are respectively connected to the two sets of screens. The material distribution component 9 is located above the feed hopper 10. Furthermore, to enable the equipment to automatically balance the flow of material in the upper channel 11 and the lower channel... The material distribution component 9 also includes a material distribution plate 91 and a connecting shaft 94. The material distribution plate 91 is hinged to the screen box 2 via the connecting shaft 94. A stop bar 92 is provided above the material distribution plate 91, and a counterweight block 93 is connected to the bottom surface of the material distribution plate 91. Multiple sets of stop bars 92 are provided. A torsion spring is provided at the connection between the connecting shaft 94 and the screen box 2. The inlet size of the feed hopper 10 is adapted to the material distribution plate 91. A groove adapted to the counterweight block 93 is provided on the feed hopper 10, so that the input material can be fed into the upper channel 11 and the lower channel in turn.

[0026] As one implementation method in this embodiment, in order to prevent the polled input material from falling directly into the finished product channel 12 without sorting, the feeding component 3 also includes a feeding port 31 and a side frame 32. The feeding port 31 is connected to the top of the side frame 32, and a positioning plate 33 is connected inside the side frame 32. The positioning plate 33 is adapted to the position and size of the finished product channel 12. The positioning plate 33 is located below the material distribution component 9. The positioning plate 33 is used to quickly position the installation position of the side frame 32, and at the same time, it can also prevent the material from falling directly into the finished product channel 12.

[0027] As one implementation method in this embodiment, in order to output the sorted materials separately, the discharge assembly 4 further includes an upper discharge channel 41, a lower discharge channel 42, and a finished product discharge channel 43. The upper discharge channel 41, lower discharge channel 42, and finished product discharge channel 43 correspond one-to-one with the positional dimensions of the upper channel 11, lower channel, and finished product channel 12, respectively. Each of the upper discharge channel 41, lower discharge channel 42, and finished product discharge channel 43 is connected to a discharge port 45, allowing the sorted materials to be output separately through their corresponding discharge channels. The upper discharge channel 41 and... A second filter hole 46 is provided at the connection of the lower discharge channel 42, penetrating the upper discharge channel 41 and the lower discharge channel 42. A first filter hole 44 is provided at the connection of the lower discharge channel 42 and the finished product discharge channel 43, penetrating the lower discharge channel 42 and the finished product discharge channel 43. Multiple sets of the first filter hole 44 and the second filter hole 46 are provided. The aperture of the first filter hole 44 and the aperture of the second filter hole 46 are the same as the aperture of the screen, so that the fine particles that are stuck on the material before the material is output can still fall down into the finished product discharge channel 43 through the first filter hole 44 and the second filter hole 46.

[0028] The working principle of this practical device is as follows: First, power on the equipment, then start the vibration source 5. The vibration source 5 drives the screen box 2 to vibrate and sort. Then, the material is first fed into the feeding assembly 3 through the inlet 31. The material first falls onto the distribution plate 91 in the distribution assembly 9. Smaller materials pass directly through the gap between the baffles 92 on the distribution plate 91, while larger materials fall onto the baffles 92. When the force exerted by the material on the distribution plate 91 on the baffles 92 is greater than the force exerted by the torsion spring on the connecting shaft 94 and the counterweight 93 on the distribution plate 91, the distribution plate 91 rotates around the connecting shaft 94, causing the material on the distribution plate 91 to enter the upper channel 11. Simultaneously, the distribution plate 91 blocks the upper channel 11, and subsequent material input falls directly into the lower channel through the feed hopper 10. When the material on the distribution plate 91 is emptied, the position of the distribution plate 91 is reset under the action of the torsion spring and the counterweight 93, and the material returns to the screen box. After internal vibration sorting, under the action of the screen, smaller materials in the upper channel 11 fall into the finished product channel 12 after being screened by two sets of screens. Materials in the lower channel fall into the finished product channel 12 after being sorted by one set of screens. The sorted materials in the upper channel 11 are output through the upper discharge channel 41. When the materials pass through the second filter hole 46 on the upper discharge channel 41, they are further sorted to improve the sorting effect. Finally, they are output through the discharge port 45 on the upper discharge channel 41. The sorted materials in the lower channel are output through the lower discharge channel 42. When the materials pass through the first filter hole 44 on the lower discharge channel 42, they are further sorted to improve the sorting effect. Finally, they are output through the discharge port 45 on the lower discharge channel 42. The sorted materials in the finished product channel 12 are output through the finished product discharge channel 43 and finally through the discharge port 45 on the finished product discharge channel 43.
