Abstract
Description
Technical Field
[0001] This utility model belongs to the field of dryer technology, specifically relating to a conveyor belt cleaning device and a dryer including the above-mentioned conveyor belt cleaning device. Background Technology
[0002] The conveyor belt is an important component of a feed dryer. On one hand, it is responsible for transporting the materials entering the dryer from the inlet to the outlet, completing the material handling work. On the other hand, during the material handling process, the hot air of the dryer penetrates the materials on the conveyor belt, exchanging moisture and heat with the materials, removing the moisture from the materials, and achieving the drying effect.
[0003] Its shortcomings are:
[0004] First, during the operation of the dryer, it was found that when the track plates pass over the sprockets, some material easily enters the interior of the dryer track plates during the meshing process. This material then tumbles inside as the track plates move, making it impossible to discharge. This residual material increases the amount of residue inside the dryer, affecting the hygienic quality of the feed.
[0005] Secondly, during operation, as materials are in contact with the track plates for a long time, some of the materials will block the holes on the track plates. Over time, this will affect the efficiency of hot air passage through the dryer's track plates, resulting in a decrease in the dryer's capacity and an increase in energy consumption. Utility Model Content
[0006] The first objective of this invention is to provide a conveyor belt cleaning device to solve the technical problem of material residue inside the track plates of existing dryers being unable to be discharged, resulting in increased energy consumption.
[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a conveyor belt cleaning device, including a driven wheel assembly, characterized in that a first cleaning component is provided on the driven wheel assembly, and the rotation of the driven wheel assembly drives the first cleaning component to rotate, thereby conveying the accumulated material on the conveyor belt at the location of the driven wheel assembly to the end of the driven wheel assembly and discharging it.
[0008] This invention utilizes the rotation of the driven shaft during the drying process and adds a first cleaning component to the driven shaft. The structure is simple and convenient for real-time cleaning. The driven shaft rotates continuously during the drying process, which can continuously clean the material entering the dryer and avoid the accumulation of a large amount of material.
[0009] To solve the technical problem of low efficiency in discharging residual material from one end, this utility model adopts the following technical solution: the first cleaning component includes a first cleaning conveyor and a second cleaning conveyor, which are respectively disposed at both ends of the driven wheel assembly; the first cleaning conveyor and the second cleaning conveyor rotate in opposite directions.
[0010] The rotation of the driven wheel assembly drives the first cleaning conveyor and the second cleaning conveyor to rotate in the opposite direction, thereby conveying the accumulated material on the track at the location of the driven wheel assembly to both ends of the driven wheel assembly and discharging it.
[0011] This invention sets the first cleaning component as a structure with simultaneous discharge from both ends, improving discharge efficiency. The driven shaft has only one direction of rotation, and the first cleaning conveyor and the second cleaning conveyor are respectively configured on the driven shaft to guide the material from the middle to both sides, and finally discharge it from the track plates from both sides, thereby avoiding a large amount of material residue inside the track plates.
[0012] To solve the technical problem of how to implement the first and second cleaning conveying components, the present invention adopts the following technical solution: the first cleaning conveying component is a continuous spiral structure, and the second cleaning conveying component is a continuous spiral structure, which is simple in structure and convenient for real-time operation.
[0013] To solve the technical problem of how to realize a continuous spiral structure, the present invention adopts the following technical solution: the first cleaning and conveying component is a spiral blade; the second cleaning and conveying component is a spiral blade.
[0014] To solve the technical problem of how to implement the first and second cleaning and conveying components, the present invention adopts the following technical solution: the first cleaning and conveying component is a discontinuous spiral structure, and the second cleaning and conveying component is a discontinuous spiral structure.
[0015] To solve the technical problem of how to realize a discontinuous spiral structure, the present invention adopts the following technical solution: the first cleaning and conveying component includes a plurality of spiral blades arranged at intervals.
[0016] The second cleaning conveyor includes a plurality of spiral blades arranged at intervals; the spiral direction of the second spiral blades is opposite to that of the first spiral blades.
[0017] To solve the technical problem of how to implement the first and second cleaning and conveying components, the present invention adopts the following technical solution: the first cleaning and conveying component includes a plurality of first deflecting plates arranged in a spiral and at intervals;
[0018] The second cleaning and conveying component includes several spirally arranged and spaced second deflector plates; the spiral direction of the second deflector plates is opposite to that of the first deflector plates. The driven shaft has only one direction of rotation, and the first and second deflector plates are respectively arranged on the driven shaft to guide the material from the middle to both sides, and finally discharge it from the track plates from both sides, thereby avoiding a large amount of material residue inside the track plates.
[0019] To further solve the technical problem of material residue in the conveyor belt, this utility model adopts the following technical solution: the driven wheel assembly includes a driven shaft, the driven shaft is a hollow shaft, and a second cleaning assembly is provided on the driven shaft, including:
[0020] An air vent is provided on the driven shaft;
[0021] Rotary joints are located at both ends of the driven shaft;
[0022] A high-pressure blower is provided with an air inlet and an air outlet; the air outlet is connected to the rotary joint via a corresponding high-pressure air pipe; the air inlet is used for replenishing air.
[0023] This invention modifies the structure of the driven shaft, utilizing high-pressure air to clear material clogging the track plates. The driven shaft adopts a hollow shaft structure, with additional openings. Furthermore, both sides of the driven shaft are connected to a high-pressure blower via rotary joints. This allows air from the high-pressure blower to enter the driven shaft through the rotating structure, then exit through the hollow tube within the shaft, using the high-pressure air to clear the material clogging the track plates, thus achieving material removal.
[0024] To solve the technical problem of how to implement the driven wheel assembly, the present invention adopts the following technical solution: the driven wheel assembly further includes a first driven wheel and a second driven wheel, which are disposed at both ends of the driven shaft.

[0037] The present invention will be further described below with reference to the accompanying drawings.
[0038] Comparison Example
[0039] like Figure 1 As shown, the conveyor belt 120 of the existing dryer 100 is located between the driving wheel structure 110 and the driven wheel structure 130. The driving wheel structure 110 is driven by a geared motor, and then the entire conveyor belt is verified to operate stably between the driving wheel structure 110 and the driven wheel structure 130.
[0040] like Figure 2 As shown, the driven wheel structure 130 of the existing dryer 100 has a first driven wheel 131 and a second driven wheel 132 on both sides, and a driven shaft 133 in the middle. When the motor drives the driving wheel structure 110, the first driven wheel 131 and the second driven wheel 132 also rotate together under the action of the chain on the conveyor belt 120.
[0041] In actual use, it was found that material 140 often enters the conveyor belt near the driven wheel structure 120.
[0042] Example 1
[0043] This embodiment, while maintaining the basic structure of the existing main body, improves the driven shaft of the drive track plate to solve the problems of material entering the conveyor belt and material accumulation inside the track plate, as described in the comparative example. The structural improvement utilizes the rotational characteristics of the driven wheel assembly.
[0044] like Figure 3 As shown, the conveyor belt cleaning device 200 includes a driven wheel assembly 210. The driven wheel assembly 210 includes a driven shaft 211, a first driven wheel 212, and a second driven wheel 213. The first driven wheel 212 and the second driven wheel 213 are respectively installed at both ends of the driven shaft 211.
[0045] A first cleaning component 220 is provided on the driven wheel assembly 210. When the driven wheel assembly 210 rotates, it drives the first cleaning component 220 to rotate, thereby conveying the accumulated material on the track at the location of the driven wheel assembly to the end of the driven wheel assembly and discharging it.
[0046] This invention utilizes the rotation of the driven shaft during the drying process, adding a first cleaning component to the driven shaft. The structure is simple and convenient for real-time cleaning. Furthermore, because the driven shaft rotates continuously during the drying process, this structure can continuously clean the material entering the dryer, preventing large-scale material accumulation.
[0047] In one embodiment, such as Figure 3 As shown, the first cleaning assembly 220 includes a first cleaning conveyor 221 and a second cleaning conveyor 222. The first cleaning conveyor 221 and the second cleaning conveyor 222 are respectively disposed at both ends of the driven wheel assembly 210; the rotation directions of the first cleaning conveyor 221 and the second cleaning conveyor 222 are opposite.
[0048] The driven wheel assembly 210 rotates, causing the first cleaning conveyor 221 and the second cleaning conveyor 222 to rotate in the opposite direction, thereby conveying the accumulated material on the track at the location of the driven wheel assembly to both ends of the driven wheel assembly 210 and discharging it.
[0049] In one embodiment, both the first cleaning conveyor 221 and the second cleaning conveyor 222 have a continuous spiral structure. Specifically, as shown... Figure 3 As shown, the first cleaning and conveying component is a left-handed blade; the second cleaning and conveying component is a right-handed blade.
[0050] In one embodiment, the first cleaning conveyor 221 is a discontinuous spiral structure, and the second cleaning conveyor 222 is a discontinuous spiral structure.
[0051] Specifically, the first cleaning and conveying component 221 includes a plurality of first spiral blades arranged in a spiral and spaced apart;
[0052] The second cleaning and conveying component includes several spiral blades arranged at intervals; the spiral direction of the second spiral blades is opposite to that of the first spiral blades.
[0053] like Figure 4 As shown, in one embodiment, the first cleaning conveyor 221 includes a plurality of first deflecting plates arranged in a spiral and spaced apart. The second cleaning conveyor 222 includes a plurality of second deflecting plates arranged in a spiral and spaced apart. The second deflecting plates face opposite directions to the first deflecting plates.
[0054] To address the issue of material accumulation inside the track plates, a first material cleaning component is added to the driven shaft. During the operation of the driven shaft, the accumulated material that has entered the track plates is discharged to both sides and then exited from inside the track plates through both sides.
[0055] A spiral guide structure is added to the driven shaft. Since the driven shaft can only rotate in one direction, a left-hand spiral and a right-hand spiral are respectively configured on the driven shaft to guide the material from the middle to both sides, and finally discharge it from the track plates from both sides, thereby avoiding a large amount of material residue inside the track plates.
[0056] Right-hand and left-hand spiral blades are welded onto the driven shaft. During normal operation of the dryer, the material accumulated inside the conveyor belt is propelled towards both ends of the driven shaft by the action of the left-hand and right-hand blades, ultimately exiting the conveyor belt from both ends. The biggest advantage of this structure is that it utilizes the continuous rotation of the driven shaft; simply adding spiral blades is sufficient to discharge the material. Because the direction of rotation of the driven shaft is fixed, the left-hand and right-hand spiral blades facilitate material discharge.
[0057] In one embodiment, such as Figure 5 As shown, the driven shaft 211 is a hollow shaft. A second cleaning assembly 230 is provided on the driven shaft 211, including an air outlet, a rotary joint 232, and a high-pressure blower 233.
[0058] The air vents are radially spaced on the driven shaft 211. Rotary joints 232 are installed at both ends of the driven shaft 211.
[0059] The high-pressure blower 233 is equipped with an air inlet 2331 and an air outlet 2332. The air outlet 2332 is connected to the rotary joint 232 via a corresponding high-pressure air pipe 234; the air inlet 2331 is used for replenishing air.
[0060] This invention modifies the structure of the driven shaft to utilize high-pressure air to clean material clogging the track plates. The modified driven shaft is hollow and features additional openings. Both sides of the driven shaft are connected to a high-pressure blower via rotary joints. Air from the blower enters the driven shaft through the rotating structure and is then expelled from the hollow tube within the shaft through the outlet, thus cleaning the material.
[0061] In one embodiment, the second cleaning assembly 230 further includes nozzles 231. The nozzles 231 are radially spaced on the driven shaft 211; the hollow driven shaft 211 is radially provided with threaded holes, and the nozzles 231 are threaded into the threaded holes on the driven shaft 211.
[0062] This invention adds an opening to the driven shaft and then configures a nozzle; the air from the high-pressure blower can enter the driven shaft through the rotating structure, and then enter the nozzle through the hollow tube in the driven shaft, and is sprayed out from the nozzle, thereby cleaning the material.
[0063] This invention utilizes a nozzle to clean the track plates, which can be done whether the dryer is running unloaded or with material, and is not limited by the operating conditions of the dryer, thus improving the efficiency of track plate cleaning.
[0064] This invention still utilizes the characteristic of a rotating driven shaft, replacing the original driven shaft 211 with a hollow driven shaft 211. Holes are then drilled in the hollow driven shaft 211, and nozzles 231 are installed, transforming the hollow driven shaft 211 into a spray pipe. Simultaneously, a rotary joint 232 is installed at each end of the hollow driven shaft 211. A high-pressure blower 233 is used outside the dryer to pressurize ambient air, which then flows along the high-pressure air pipe 234 into the rotary joints 232, then through the rotary joints 232 into the hollow driven shaft 211, and finally is sprayed out through the nozzles 231. During the spraying process, material clogging the conveyor belts is promptly cleared, thereby improving the drying efficiency of the dryer and saving energy.
[0065] To address the problem of material accumulation inside the conveyor belt during dryer operation, this invention adds a first and a second cleaning conveyor to the driven shaft. The rotation of the driven shaft allows the accumulated material to be conveyed to both ends for discharge. Simultaneously, the driven shaft is made hollow with threaded holes for nozzles. High-pressure air from a high-pressure blower is then sprayed through these nozzles to blow away material from the conveyor belt, preventing material blockage and reducing dryer efficiency. This further saves energy and improves energy efficiency.
