Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, specifically to a material collection device for a multi-channel drying device. Background Technology

[0002] In industrial applications, silica sludge, after acid washing and filter pressing, needs to be dried promptly and transferred to subsequent processing or storage stations. Current technology typically employs a "single-machine drying + single-machine storage bin + forklift / overhead crane batch transfer" model, which is mostly a decentralized design. Adding conveyor devices involves installing a separate screw conveyor or belt conveyor below the discharge port of each dryer, followed by centralized material collection via secondary transfer equipment. In this operating model, the horizontal arrangement of multiple independent collection and conveying devices results in a large footprint, especially in compact production lines, leading to high equipment costs and low transfer efficiency. Utility Model Content

[0003] The multi-channel drying device provided by this utility model is designed to solve the problem of low operating efficiency caused by multiple transfer links and dispersed equipment in existing drying equipment.

[0004] To address the aforementioned problems, this utility model provides a multi-channel drying unit material collection device for collecting and transporting dried materials from a drying unit integrating multiple dryers to a storage silo or production line. The device is installed in a sunken trench at the end of the drying unit. The multi-channel drying unit material collection device includes a scraper conveyor located at the bottom of the dryer unit's outlet. The top of the scraper conveyor is positioned at the bottom of the sunken trench, and its end is supported by a first support, the height of which is higher than the ground level. Inclined guide chutes are installed on both sides of the top of the scraper conveyor, guiding the dried material discharged from each dryer to the top of the scraper conveyor. A discharge port is located at the tail end of the scraper conveyor, situated at the inlet end of the storage silo or production line. The above solution involves adding a sunken trough and an inclined scraper conveyor at the end of the integrated dryer unit to achieve centralized collection of drying materials from the multi-channel dryer, reduce transfer links, save ground space, and collect and transport materials while drying, thus enabling the entire production line to operate and significantly improving work efficiency.

[0005] Furthermore, the scraper conveyor includes a U-shaped sealed channel, a double closed-loop chain on both sides of the inner wall of the U-shaped rice noodle channel, several scrapers arranged at intervals along the closed-loop chain, and a variable frequency motor located at one end of the closed-loop chain and driving the sprocket. The motor drives the sprocket to drive the closed-loop chain to circulate along a preset path. The scrapers push the material in the U-shaped sealed channel, and the material is delivered from the top to the discharge end. The material is in direct contact with the scrapers and is conveyed by the chain traction force.

[0006] Furthermore, in order to make the angle at which the dried material slides toward the scraper conveyor adjustable when the inclined guide trough receives the dried material, the inclined guide trough provided in this embodiment includes a U-shaped trough plate and a second support. The second support is connected to the receiving section of the U-shaped trough plate through a hinge assembly. The unloading section of the U-shaped trough plate overlaps the top of the side wall of the U-shaped sealed channel. The second support can adopt a telescopic structure. By adjusting the height of the second support frame, the inclination angle of the U-shaped trough plate can be adjusted, the falling speed of the material can be controlled, and the impact force of the material can be prevented from being too large or too small, so that the material can enter the scraper conveyor smoothly.

[0007] Furthermore, in order to achieve efficient conveying of dried materials and to transport blocky and granular dried materials of different sizes together, the scraper conveyor provided in this embodiment includes a receiving section, an lifting section, and a leveling conveying section. The receiving section is located at the bottom of the dryer unit and is used to horizontally receive the dried materials to prevent them from accumulating at the lowest point. The lifting section is connected to the end of the receiving section and is used to lift the dried materials to ground level. The leveling conveying section is connected to the end of the lifting section and is used to transport the dried materials to the storage silo or production line. The end of the leveling conveying section is integrated with a discharge port.

[0008] Furthermore, in order to achieve the lifting efficiency and stability of the balancing device, the lifting section provided in this embodiment has an angle of 30° to 60° with the horizontal plane.

[0009] Furthermore, in order to prevent the material in the U-shaped trough from rushing down at high speed and thus rushing out of the receiving range of the scraper conveyor, the top three sides of the U-shaped sealing trough provided in this embodiment are equipped with baffle plates.

[0010] Preferably, since the material falls with lateral impact or rebound, in order to prevent it from splashing out from the open side, the baffle provided in this embodiment includes a rear baffle and a side baffle. The rear baffle is located at the top of the receiving section, and the side baffles are located on both sides of the receiving section. The three sides are closed to form a funnel-shaped enclosed structure, so that the material from the discharge port is constrained within the receiving area of ​​the scraper conveyor.

[0011] The technical advantages of this application are as follows: This application provides a material collection device for a multi-channel drying unit. Through the above scheme, a sunken trough and an inclined scraper conveyor are added to the end of the integrated drying unit to realize the centralized collection of drying materials from the multi-channel dryer, reduce transfer links, save ground space, collect and transport materials while drying, and enable the entire production line to operate, significantly improving the efficiency of transfer operations.

[0018] The following will be combined with the appendix Figures 1-5 The embodiments of the technical solution of this application are described in detail below. The following embodiments are only used to illustrate the technical solution of this application more clearly, and are therefore only examples and should not be used to limit the scope of protection of this application.

[0019] Example 1 Reference Figures 1-4To address the problem of low operational efficiency caused by multiple transfer links and dispersed equipment in existing drying equipment systems, this utility model provides a multi-channel drying device material collection device. This device collects and transports the dried material from a drying unit 1000 integrating multiple dryers to a storage silo or production line. The device is installed within a sunken trench 2001 created on the ground 2000 at the end of the drying unit 1000. The multi-channel drying device material collection device includes a discharge port 1 located at the dryer unit 1000. The scraper conveyor 2 at the bottom of 001 has its top end placed at the bottom of the sunken trench 2001, and its end is supported by the first bracket 230, which is higher than the ground 2000. Inclined guide chutes 1 are installed on both sides of the top of the scraper conveyor 2. The inclined guide chutes 1 are used to guide the dried material discharged from each dryer 1000 to the top of the scraper conveyor 2. The tail end of the scraper conveyor 2 is provided with a discharge port 240, which is located at the feed end of the storage bin or the production line. Wet material enters through the feed inlet of dryer unit 1000, undergoes rotary drying by the dryer unit 1000, and is then conveyed by scraper conveyor 2 installed in the sunken trough 2001, so that the discharge port 1001 of dryer unit 1000 is above the top of scraper conveyor 2, forming a gravity-feed space. This simplifies the overall structural height of the conveying system. The dried material then falls from the discharge port 1001 into the highest point of the inclined guide trough 1, and slides along the inclined guide trough 1 into the top of scraper conveyor 2 by its own gravity. The scraper conveyor 2 then conveys the dried material at an inclined level, transporting it to the discharge port 240 above ground level 2000, and finally into a storage silo or the feed end of the production line. In practice, dryer unit 1000 can operate simultaneously, while scraper conveyor 2 continues to rotate and convey material without stopping.

[0020] By adding a sunken trough 2001 and an inclined scraper conveyor 2 at the end of the integrated dryer unit 2000, the material to be dried in the multi-channel dryer is collected in a centralized manner, reducing the transfer links and saving ground space. The material is collected and transported at the same time as drying, which makes the entire production line work and significantly improves the efficiency of operation.

[0021] The scraper conveyor 2 includes a U-shaped sealed channel 210, a double closed-loop chain 250 disposed on the inner walls of both sides of the U-shaped sealed channel 210, a number of scrapers 260 arranged at intervals along the closed-loop chain 250, and a variable frequency motor 220 disposed at one end of the closed-loop chain 250 and driving the sprocket. The motor 220 is used to drive the sprocket to drive the closed-loop chain 250 to circulate along a preset path. The scrapers 260 push the material in the U-shaped sealed channel 210, and the material is sent from the top to the discharge end. The material is in direct contact with the scrapers 260 and is conveyed by the chain traction force.

[0022] To ensure that the angle at which the dried material slides towards the scraper conveyor 2 is adjustable when the inclined guide chute 1 receives the dried material, the inclined guide chute 1 provided in this embodiment includes a U-shaped trough plate 101 and a second support 102. The second support 102 is connected to the receiving section of the U-shaped trough plate 101 through a hinge assembly. The unloading section of the U-shaped trough plate 101 overlaps the top of the side wall of the U-shaped sealed channel 210. The second support 102 can adopt a telescopic structure. By adjusting the height of the second support frame 102, the inclination angle of the U-shaped trough plate 101 can be adjusted, controlling the falling speed of the material and preventing the material impact force from being too large or too small, so that the material can smoothly enter the scraper conveyor 2.

[0023] Example 2 See attached document Figure 5 According to the first embodiment described above, this application also provides another embodiment of a multi-channel drying device material collection device. To achieve efficient conveying of dried materials, and to convey blocky and granular dried materials of different sizes together, the scraper conveyor 2 provided in this embodiment includes a receiving section 211, an lifting section 212, and a leveling conveying section 213. The receiving section 211 is located at the bottom of the drying unit 1000 and is used to horizontally receive the dried materials, preventing them from accumulating at the lowest point. The lifting section 212 is connected to the end of the receiving section 211 and is used to lift the dried materials to a height of 2000 meters above the ground. The leveling conveying section 213 is connected to the end of the lifting section 212 and is used to convey the dried materials to a storage silo or production line. The end of the leveling conveying section 213 integrates a discharge port 240. The leveling conveying section 213 can connect to multiple conveyor chains to extend the conveying distance or achieve multi-point unloading.

[0024] In order to achieve the lifting efficiency and stability of the balancing device, the lifting section 212 provided in this embodiment has an angle of 30° to 60° with the horizontal plane.

[0025] In order to prevent the material in the U-shaped trough 101 from rushing down at high speed and thus rushing out of the receiving range of the scraper conveyor 2, the top three sides of the U-shaped sealing trough 210 provided in this embodiment are equipped with baffle plates 3.

[0026] Since the material falls with lateral impact or rebound, in order to prevent it from splashing out from the open side, the baffle plate 3 provided in this embodiment includes a rear baffle plate 310 and a side baffle plate 320. The rear baffle plate 310 is located at the top of the receiving section 211, and the side baffle plate 320 is located on both sides of the receiving section 211. The three sides are closed to form a funnel-shaped enclosed structure, so that the material from the discharge port 1001 is constrained within the receiving area of ​​the scraper conveyor 2.
