Description
Technical Field
[0001] This utility model relates to the field of abrasive drying technology, specifically to an abrasive drying mechanism after water washing. Background Technology
[0002] Abrasives are sharp, hard materials used to grind the surfaces of softer materials. Abrasives are broadly classified into natural and synthetic abrasives. They are also categorized by hardness into superhard and ordinary abrasives. The range of abrasives is vast, from soft household detergents and gemstone abrasives to the hardest material, diamond. Abrasives are essential materials in the manufacture of every precision product. Many natural abrasives have been replaced by synthetic abrasives.
[0003] In the abrasive manufacturing process, the dust adhering to the surface of the abrasive is necessary to ensure the quality of the finished abrasive. This is typically achieved by washing the abrasive several times with water to remove fine dust and impurities. After drying, the abrasive is conveyed to a drying chamber. However, the surface of the washed abrasive still has a large amount of water residue, and the abrasive particles are small. When entering the drying chamber, the abrasive particles overlap, with those inside being blocked by others, resulting in slow drying and low overall drying efficiency. Furthermore, some of the evaporated water vapor is not discharged and adheres to the inside of the drying chamber, corroding internal parts and reducing their service life. Therefore, we propose a drying mechanism for abrasives after washing. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an abrasive drying mechanism after water washing. Before drying, the abrasive is laid flat and preheated with hot air and the surface water is blown away, thereby improving the drying efficiency and extending the service life of the equipment. This can effectively solve the problems in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an abrasive drying mechanism after water washing, comprising a conveyor belt and an air blowing mechanism;
[0006] Conveyor belt: A drying box is installed at its front end;
[0007] Air blowing mechanism: It includes a feed hopper, filter plate, rotating drum and motor. The rear end of the conveyor belt is fixedly connected to the feed hopper through a bracket one. The lower end of the feed hopper is rotatably connected to the rotating drum. The outer arc surface of the rotating drum is tangent to the front side of the feed hopper. The right side of the feed hopper is fixedly connected to the motor. The output shaft of the motor is fixedly connected to the right end of the rotating drum. The lower end of the feed hopper is fixedly connected to the filter plate. The rotating drum is located at the upper end of the filter plate. The middle part of the conveyor belt is fixedly connected to evenly distributed air knives through a bracket two. The air knives are all located at the upper end of the filter plate. Before drying, the abrasive is spread flat, and hot air is used to preheat the abrasive and blow away the surface water, thereby improving the drying efficiency and extending the service life of the equipment.
[0008] Furthermore, it also includes a control switch group, which is located on the left side of the conveyor belt. The input end of the control switch group is electrically connected to an external power source, and the input ends of the conveyor belt and the motor are electrically connected to the output end of the control switch group to control the opening and closing of electrical appliances.
[0009] Furthermore, the air blowing mechanism also includes a sprocket and a stirring shaft. The stirring shaft is rotatably connected between the inner walls of the left and right sides of the feed hopper. The left end of the stirring shaft and the left end of the rotating drum are both fixedly fitted with sprockets. The two sprockets are connected by chain drive to avoid material blockage at the feed hopper outlet.
[0010] Furthermore, the air blowing mechanism also includes a lower baffle, which is fixedly connected to the lower end of the filter plate to collect the blown-down water.
[0011] Furthermore, a hot air blower is placed on the right side of the conveyor belt. The output port of the hot air blower is fixedly fitted with a connecting pipe. The air inlets of the air knives are all connected to the connecting pipe. The input end of the hot air blower is electrically connected to an external power source to provide hot air.
[0012] Furthermore, a support frame is fixedly connected to the front end of the conveyor belt. The support frame is located inside the drying chamber. A heating wire is fixedly connected to the top wall of the support frame. The input end of the heating wire is electrically connected to the output end of the control switch group to achieve drying.
[0013] Furthermore, heat insulation curtains are fixedly connected to both the front and rear ends of the drying oven. The heat insulation curtains are rubber heat insulation curtains to reduce heat loss.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This abrasive drying mechanism after water washing has the following advantages:
[0015] 1. When the abrasive inside the feed hopper is fed out by the rotating drum, it is spread into a thin layer. The thickness of the abrasive layer is the distance between the outer arc surface of the rotating drum and the inner wall of the rear side of the feed hopper, which facilitates subsequent air blowing and drying.
[0016] 2. The abrasive slides downward on the upper surface of the filter plate. Hot air is blown out through the air knife, and most of the water on the surface of the abrasive is blown down to the baffle. At the same time, the hot air preheats the abrasive. When it enters the drying box, the water on the surface of the abrasive is greatly reduced, the drying is more thorough, and the corrosion of the inside of the drying box by water vapor is avoided.

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.
[0023] Please see Figure 1-4 This embodiment provides a technical solution: an abrasive drying mechanism after water washing, including a conveyor belt 1 and an air blowing mechanism 2;
[0024] Conveyor belt 1: A drying chamber 7 is set at its front end. A support frame 8 is fixedly connected to the front end of the conveyor belt 1. The support frame 8 is located inside the drying chamber 7. A heating wire 9 is fixedly connected to the top wall of the support frame 8. The input end of the heating wire 9 is electrically connected to the output end of the control switch group 6. Heat insulation curtains 10 are fixedly connected to both the front and rear ends of the drying chamber 7. The heat insulation curtains 10 are rubber heat insulation curtains. Then the abrasive is brought into the drying chamber 7. The heating wire 9 heats the abrasive again to thoroughly dry the abrasive. The heat insulation curtains 10 on the front and rear sides of the drying chamber 7 reduce heat loss.
[0025] Air blowing mechanism 2: It includes a feed hopper 21, a filter plate 25, a rotating drum 26, and a motor 27. The rear end of the conveyor belt 1 is fixedly connected to the feed hopper 21 via a bracket. The lower end of the feed hopper 21 is rotatably connected to the rotating drum 26. The outer arc surface of the rotating drum 26 is tangent to the front side of the feed hopper 21. The right side of the feed hopper 21 is fixedly connected to the motor 27. The output shaft of the motor 27 is fixedly connected to the right end of the rotating drum 26. The lower end of the feed hopper 21 is fixedly connected to the filter plate 25. The rotating drum 26 is located above the filter plate 25. The conveyor belt 1... A uniformly distributed air knife 5 is fixedly connected to the middle section via a bracket 2. All air knives 5 are located at the upper end of the filter plate 25. The air blowing mechanism 2 also includes a sprocket 23 and a stirring shaft 24. The stirring shaft 24 is rotatably connected between the inner walls of the left and right sides of the feed hopper 21. Sprockets 23 are fixedly fitted onto the left end of the stirring shaft 24 and the left end of the rotating drum 26. The two sprockets 23 are connected by a chain drive. The air blowing mechanism 2 also includes a lower baffle 22, which is fixedly connected to the lower end of the filter plate 25. A hot air blower 3 is placed on the right side of the conveyor belt 1. The output port of machine 3 is fixedly fitted with a connecting pipe 4. The air inlets of the air knife 5 are all connected to the connecting pipe 4. The input end of the hot air blower 3 is electrically connected to an external power source. When motor 27 starts, it drives the rotating drum 26 and the sprocket 23 on the left side of the rotating drum 26 to rotate. Through the transmission of the two sprockets 23, the stirring shaft 24 is driven to rotate. The stirring shaft 24 stirs the abrasive at the outlet of the feed hopper 21, making it easier for the abrasive to fall into the gap between the rotating drum 26 and the rear side wall of the feed hopper 21. The rotation of the rotating drum 26 carries the abrasive out to the filter plate 25. When the abrasive is spread into a thin layer, the filter plate 25 is tilted downwards. Under gravity, the abrasive slides down. The diameter of the filter holes in the filter plate 25 is smaller than the diameter of the abrasive, so the abrasive will not pass through the filter plate 25. The hot air blown by the ...
[0026] It also includes a control switch group 6, which is located on the left side of the conveyor belt 1. The input end of the control switch group 6 is electrically connected to an external power source, and the input ends of the conveyor belt 1 and the motor 27 are electrically connected to the output end of the control switch group 6.
[0027] The working principle of the abrasive drying mechanism after water washing provided by this utility model is as follows: The washed abrasive is poured into the feed hopper 21. The motor 27 starts, driving the rotating drum 26 and the sprocket 23 on the left side of the drum 26 to rotate. Through the transmission of the two sprockets 23, the stirring shaft 24 rotates. The stirring shaft 24 stirs the abrasive at the outlet of the feed hopper 21, facilitating the abrasive to fall into the gap between the rotating drum 26 and the rear side wall of the feed hopper 21. The rotating drum 26 carries the abrasive out to the filter plate 25, where it is spread into a thin layer. The filter plate 25 tilts downwards, and the abrasive slides down due to gravity. The diameter of the filter holes in the filter plate 25... If the diameter of the abrasive is smaller than that of the filter plate 25, the abrasive will not pass through the filter plate 25. The hot air blower 3 is started, and the hot air sent by the hot air blower 3 enters each air knife 5 through the connecting pipe 4. The hot air blows from the air knife 5 to the abrasive at the top of the filter plate 25. Most of the water on the surface of the abrasive is blown to the lower baffle 22, and a small part of the water evaporates. The hot air passing through the filter plate 25 continues to blow to the lower baffle 22, causing the water on the upper surface of the lower baffle 22 to evaporate. The abrasive with the surface moisture removed falls to the top of the conveyor belt 1, and then the abrasive is carried into the drying chamber 7. The heating wire 9 heats the abrasive again to thoroughly dry it. The heat insulation curtains 10 on the front and back sides of the drying chamber 7 reduce heat loss.
[0028] It is worth noting that the conveyor belt 1 disclosed in the above embodiments can be a DL-2053 electric conveyor belt, the motor 27 can be a DPG geared motor, the hot air blower 3 can be an HFY-200HP high-pressure hot air blower, the air knife 5 can be an SR-F100S air knife, the heating wire 9 can be a TZM heating wire, and the control switch group 6 is provided with switch buttons corresponding to the conveyor belt 1, the motor 27 and the heating wire 9 for controlling their switching operation.
