Description

Technical Field

[0001] This utility model relates to the field of material drying technology, and in particular to a fully automatic viscous material dryer. Background Technology

[0002] In many industrial production fields such as chemical, food, and pharmaceutical, drying materials is an essential core process. Currently, widely used drying equipment usually adopts hot air convection drying. For example, the material to be dried is placed on a conveyor belt and passes through a drying chamber filled with hot air as the conveyor belt moves. The moisture is removed through direct contact between the hot air and the material.

[0003] However, when dealing with highly viscous materials, the aforementioned conventional drying methods reveal significant limitations. When placed on a conveyor belt, viscous materials, due to their inherent stickiness, tend to form a static and dense layer lacking fluidity. Under the baking effect of hot air, particles on the material surface are more prone to sticking together, forming clumps of varying sizes, or even solidifying into a single block. This clumping directly prevents hot air from penetrating the material layer and entering the clumps; heat exchange is limited to the surface, resulting in a "dry outside, wet inside" situation. This leads to extremely uneven drying, requiring extended drying time to completely dry the internal moisture, reducing overall production efficiency. Furthermore, the material easily adheres to the conveyor belt surface, affecting the stability of the conveying process and increasing cleaning difficulty.

[0004] Therefore, this utility model proposes a fully automatic dryer for sticky materials to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the existing technology of fully automatic viscous material dryers, such as the easy agglomeration and sticking of materials to the wall, resulting in uneven drying and low efficiency, as well as the lack of an automatic recycling mechanism for defective products, this utility model aims to provide a fully automatic viscous material dryer with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a fully automatic viscous material dryer, including: a fixed frame, a shell, a conveyor belt, and a hot air furnace; as well as a rotating rod and a collecting shovel fixed on the rotating rod.

[0007] The rotating rod is mounted above the first conveyor belt.

[0008] Furthermore, the fully automatic sticky material dryer also includes a motor, a pulley, and a transmission belt. The motor drives the rotating rod to rotate through the transmission combination of the pulley and the transmission belt, so as to drive the collecting shovel to throw the material on the conveyor belt.

[0009] Preferably, the fully automatic viscous material dryer further includes a pulverizer, the discharge port of which is directly opposite the feed end of the conveyor belt.

[0010] Preferably, the fully automatic viscous material dryer further includes a dust collector, the dust collector's suction port being connected to the inner cavity of the outer shell.

[0011] Preferably, the end of the conveyor belt is provided with a discharge port, and a screening mechanism is provided below the discharge port.

[0012] Preferably, the screening mechanism includes a collection bucket and a cylindrical filter screen coaxially disposed inside the collection bucket; the outlet of the discharge port extends into the interior of the cylindrical filter screen; and the bottom of the collection bucket is provided with a discharge port for discharging qualified materials.

[0013] Preferably, the screening mechanism further includes a second motor, a drive shaft disposed inside the cylindrical filter screen, and spiral blades fixed on the drive shaft; the second motor is used to drive the drive shaft to rotate, so as to drive the spiral blades to transport the unqualified material screened out inside the cylindrical filter screen to one end of the cylindrical filter screen.

[0014] Preferably, the fully automatic viscous material dryer further includes a second conveyor belt, the feed end of which receives the defective material conveyed from the spiral blades, and the discharge end of the second conveyor belt extends to the feed inlet of the crusher.

[0015] Preferably, there are two rotating rods, which are symmetrically arranged on the left and right sides of the conveyor belt.

[0016] This utility model has the following beneficial effects: 1. This utility model, through a rotating rod set above the conveyor belt and a collecting shovel fixed on the rotating rod, continuously throws and turns viscous materials upward during the drying process. This solves the problem in the prior art where viscous materials are prone to clumping and sticking to the walls due to their own characteristics, resulting in insufficient hot air contact and uneven drying inside and outside. It achieves the technical effect of keeping the material in a dispersed and tumbling state in the drying chamber at all times, realizing uniform, fast and thorough drying, and significantly improving product quality and drying efficiency.

[0017] 2. This utility model, by adding a screening mechanism to screen the dried material, and automatically transporting the unqualified material screened out back to the front-end crusher for reprocessing via a conveyor belt, solves the problems of manual handling of unqualified products, production process interruption, and waste of raw materials in the prior art. It achieves closed-loop automated control of material processing, and maximizes the utilization rate of raw materials while ensuring the uniformity of the final product quality.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in 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. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0021] Example: Please refer to Figure 1 , Figure 2 and Figure 3A fully automatic viscous material dryer includes a fixed frame 1 serving as the overall mounting base. A housing 4 is bolted to the fixed frame 1. A conveyor belt 24 is horizontally positioned inside the lower part of the housing 4. The air supply pipe of a hot air furnace 22 is connected to one side of the housing 4 to provide continuous hot air into the housing 4. A crusher 21 is installed at one end of the fixed frame 1, with its discharge port facing the feed end of the conveyor belt 24. The viscous material, after being crushed by the crusher 21, can fall directly onto the conveyor belt 24. The dust collector 23 has its suction port connected to the top inner cavity of the housing 4 to absorb dust generated during the drying process. In this embodiment, a lifting assembly is installed inside the housing 4. The lifting assembly includes two rotating rods 26, which move along the conveying direction of the conveyor belt 24. The two rotating rods 26 are symmetrically arranged on the left and right sides of the conveyor belt 24 and are mounted parallel to each other. Multiple collecting shovels 29 are fixed to the outer wall of the two rotating rods 26 in a circumferentially distributed manner. The power mechanism that drives the material lifting assembly includes a motor 210, a pulley 27 and a transmission belt 28. The motor 210 is fixedly connected to the fixed frame 1. The output shaft of the motor 210 is connected to one of the rotating rods 26 through the pulley 27 and the transmission belt 28. The two rotating rods 26 are then connected to each other through a set of pulleys 27 and the transmission belt 28 to achieve synchronous rotation. When the motor 210 is working, it can drive the two rotating rods 26 to rotate synchronously in opposite directions, thereby driving all the collecting shovels 29 to continuously throw and tumble the material on the conveyor belt 24 upwards.

[0022] After the material is fully dried on the conveyor belt 24, it will move with the conveyor belt 24 to the discharge port 25 located at the end of the conveyor belt 24 and be discharged through the discharge port 25. In order to ensure the quality of the final product, this embodiment also includes a screening mechanism 3 for secondary screening and recycling. The screening mechanism 3 is set on the fixed frame 1 and located below the discharge port 25.

[0023] Please refer to Figure 1 and Figure 4The screening mechanism 3 includes a collection bucket 31 as the main support. A cylindrical filter screen 32 is coaxially arranged inside the collection bucket 31. The outlet end of the discharge port 25 passes through the side wall of the collection bucket 31 and extends into the interior of the cylindrical filter screen 32. The dried material discharged from the discharge port 25 will all enter the cylindrical filter screen 32. Material with a qualified diameter will pass through the mesh of the cylindrical filter screen 32 and fall into the bottom of the collection bucket 31, and be discharged at the discharge port 37 opened at the bottom of the collection bucket 31. However, unqualified material with an excessively large diameter will be trapped inside the cylindrical filter screen 32 to achieve automatic discharge of unqualified material. In addition to recycling, a drive shaft 34 is rotatably connected inside the cylindrical filter screen 32. A spiral blade 35 is fixedly connected to the outer wall of the drive shaft 34. The motor 33 that drives the drive shaft 34 to rotate is fixed to the outer wall of the collection bucket 31 by a bracket. The output shaft of the motor 33 is connected to the drive shaft 34 by a coupling. When the motor 33 works, it will drive the drive shaft 34 and the spiral blade 35 to rotate synchronously. The rotating spiral blade 35 will transport the unqualified material in the cylindrical filter screen 32 along the axial direction of the cylindrical filter screen 32 to one end, and finally discharge it from the opening at this end.

[0024] To achieve automated recycling and closed-loop reprocessing of non-conforming materials, please refer to... Figure 1 This embodiment also includes a second conveyor belt 36, which is installed at an angle on the fixed frame 1. The feed end of the second conveyor belt 36 is located directly below the end of the spiral blade 35 that conveys the unqualified material, and is used to receive the unqualified material discharged from the cylindrical filter screen 32. The discharge end of the second conveyor belt 36 extends upward to the feed inlet of the crusher 21, thus forming a circulation path that sends the screened unqualified material back to the crusher 21 for secondary crushing and drying. This structure ensures the complete utilization of raw materials and guarantees that all products finally discharged from the discharge port 37 are qualified products. As a specific transmission structure, the number of rotating rods 26 can be set to two, and these two rotating rods 26 are arranged parallel to the conveying direction of the conveyor belt 24, respectively symmetrically mounted on the left and right sides of the center line of the conveyor belt 24. The two rotating rods 26 are connected by an additional pulley 27 and a transmission belt 28, so as to achieve synchronous rotation in opposite directions under the drive of the motor 210. This arrangement allows the collecting shovel 29 to gather and scatter the material from both sides to the center when it throws the material up, avoiding the material being thrown against the inner wall of the outer shell 4, and making the material tumbling and mixing effect better.

[0025] Working principle: When using the drying mechanism 2 to dry viscous materials, the pulverizer 21 can pulverize the viscous materials. The pulverized materials will fall onto the conveyor belt 24 inside the outer shell 4. The conveyor belt 24 will then move the materials to the right. Hot air will be continuously blown into the outer shell 4 through the hot air furnace 22. During this process, the motor 210 will drive the left rotating rod 26 to rotate. The left rotating rod 26 will drive the right rotating rod 26 to rotate through the transmission action of the pulley 27 and the transmission belt 28. When the rotating rods 26 on both sides rotate, they will drive the multiple collection shovels 29 on their outer sides to rotate, thereby throwing the materials on the conveyor belt 24 upward, so that the materials can be dried more evenly. The dust collector 23 will absorb the dust generated inside the outer shell 4 to prevent the dust from being directly discharged. The dried materials will be conveyed to the discharge port 25 by the conveyor belt 24 for discharge. Furthermore, the material discharged through the discharge port 25 will enter the screening mechanism 3 for secondary screening. The outlet of the discharge port 25 passes through the collection bucket 31 and sends the dried material into the cylindrical filter screen 32. The material with qualified diameter will pass through the cylindrical filter screen 32 and enter the bottom of the inner side of the collection bucket 31, and be discharged through the discharge port 37. The motor 33 will drive the drive shaft 34 to rotate, and the drive shaft 34 will drive the spiral blades 35 to rotate, thereby conveying the unqualified material to the left and falling onto the conveyor belt 36 on the front side of the fixed frame 1. The conveyor belt 36 will then convey the unqualified material to the crusher 21 for secondary processing to ensure that the material discharged through the discharge port 37 is a qualified product.
