Description

Technical Field

[0001] This application relates to the field of conveying technology, specifically a drying conveying device. Background Technology

[0002] In the chemical and fertilizer manufacturing industry, equipment such as drum dryers and fluidized bed dryers are widely used to process hygroscopic granular materials such as ammonium sulfate and diammonium phosphate. These drying equipment removes moisture from the raw materials through high-temperature airflow. After drying, the raw materials can be introduced into the next process. However, in order to transfer the dried materials to the next process, the screw conveyor becomes a key connecting device.

[0003] For example, patent CN210070525U discloses a drying conveying device. This patent uses a rotating shaft with spiral blades in the material trough and a motor that drives the rotating shaft at the head end of the conveying section to convey materials from low potential to high potential according to the Archimedes spiral principle.

[0004] In the above description, in order to clean up impurities generated during the drying process or transportation, operators usually install an additional vibrating screen below the discharge port to separate impurities. However, when the workload is large, the screen is easily blocked by large particles or impurities, and the actual efficiency may be reduced. At this time, the discharge speed of the drying device far exceeds the screening capacity, causing the material to accumulate at the discharge port, thereby affecting the overall processing efficiency of the material.

[0005] Therefore, it is necessary to provide a drying and conveying device to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0032] like Figure 1 As shown, this application provides a drying and conveying device mainly used in fertilizer raw material drying production lines, for conveying dried granular fertilizer raw materials. Specifically, the drying and conveying device includes a drying device 1, which adopts a rotary flash dryer or a fluidized bed dryer in the prior art for hot air drying of materials containing moisture. In this application, the drying device 1 can be a fluidized bed dryer, and a feeding hopper 11 is provided at the top of the drying device 1 for feeding materials, while a discharge hopper 10 is provided at the bottom of the drying device 1 for discharging the dried materials.

[0033] To connect the drying and conveying processes, such as Figures 1-3 As shown, a conveying device 3 is provided on one side of the drying device 1. The conveying device 3 can be set at the top of the feeding hopper 11 of the drying device 1, so that the material can be introduced into the drying device 1 from the feeding hopper 11 through the conveying device 3. Similarly, it can be set at the bottom of the drying device 1 at the discharge hopper 10, so as to receive the material dried by the drying device 1 and then carry it out for conveying. In this embodiment, the conveying device 3 is set at the discharge hopper 10 and undertakes the function of conveying the dried material to the downstream equipment.

[0034] Specifically, the conveying device 3 includes a conveying pipe 33 fixedly installed on the upper end of the frame 31. The conveying pipe 33 is suitable for transporting materials, and an inlet 36 is provided at the lower end of the conveying pipe 33. The inlet 36 is adapted to the discharge hopper 10 of the drying device 1. The inlet 36 is suitable for introducing the dried material into the conveying pipe 33.

[0035] Meanwhile, a motor 30 is fixedly installed on one side of the conveying pipe 33. The output end of the motor 30 passes through the inside of the conveying pipe 33 and is fixedly connected to a rotating shaft 34. Thus, starting the motor 30 can drive the rotating shaft 34 to rotate inside the conveying pipe 33.

[0036] Furthermore, a spiral blade 32 is fixedly installed on the outside of the rotating shaft 34. The spiral blade 32 is spirally arranged on the outside of the rotating shaft 34. The spiral blade 32 is suitable for spirally transporting materials to facilitate transportation operations. At the same time, a discharge port 38 is opened on the upper part of the conveying pipe 33. The discharge port 38 is suitable for conveying the materials in the conveying pipe 33 to the next process.

[0037] Example 1:

[0038] In order to filter impurities in the material, such as Figures 2-4 As shown, a filter assembly 4 is provided below the discharge port 38. The filter assembly 4 includes a discharge pipe 40 fixedly installed in the discharge port 38 to facilitate subsequent discharge operations.

[0039] To achieve dynamic filtration, two sets of fixed frames 44 are symmetrically hinged at the bottom of the feed pipe 40. The fixed frames 44 are semi-circular, and each fixed frame 44 is equipped with a filter screen 45. Two sets of electric cylinders 42 are correspondingly hinged to the outer wall of the feed pipe 40. The output end of the electric cylinder 42 is hinged to the outer edge of the fixed frame 44. When the electric cylinder 42 is activated to retract, it can drive the fixed frame 44 to close the filter screen 45 and form a filter surface. The size of the filter surface matches the outlet of the feed pipe 40 so that the material can be discharged after impurities are intercepted by the filter screen 45.

[0040] When filtration begins, the electric cylinder 42 pulls the fixed frame 44 to close the filter screen 45 and form a filter surface. At this time, impurities in the material are intercepted by the filter screen 45, and the material is discharged through the filter screen 45.

[0041] After the material is discharged, the electric cylinder 42 is activated to push the fixed frames 44 at both ends to separate, so that the impurities can be poured out directly. When the fixed frames 44 are fully opened under the action of the electric cylinder 42, the impurities are completely discharged.

[0042] After the material and impurities have been completely discharged, if it is necessary to remove the impurities accumulated on the filter screen 45, the electric cylinder 42 can be activated to push the two fixed frames 44 on both sides to unfold outward, so that the filter screens 45 at both ends can be rotated to a position parallel to the axis of the feed pipe 40. At this time, the filter screen 45 is fully exposed on the outside of the feed pipe 40, which makes it convenient for manual cleaning.

[0043] Example 2:

[0044] In order to make the filter assembly 4 more flexible, at least two sets of discharge ports 38 can be set at the end of the conveying pipe 33, and a filter assembly 4 can be set at the lower end of each discharge port 38. A valve 41 can be set at each discharge pipe 40 in the filter assembly 4, so as to control the material flow path according to the actual situation.

[0045] Specifically, when the filter screen 45 in one of the filter components 4 becomes clogged and needs to be stopped for cleaning, the valve 41 corresponding to that filter component 4 is closed, and at the same time, the valve 41 of the other filter component 4 is opened, so that all the material is discharged through the discharge pipe 40 in the other filter component 4, thereby achieving operation without stopping the machine.

[0046] It should be noted that when a large amount of material needs to be transported, both sets of valves 41 can be fully opened and coordinated with the conveying device 3 to achieve the effect of rapid material transportation and discharge.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
