Description

Technical Field

[0001] This utility model relates to the field of belt dryer technology, and in particular to a belt dryer mesh belt cleaning device. Background Technology

[0002] Belt dryers use a mesh belt to transport materials and hot air to penetrate the mesh for uniform drying. However, during operation, some material can easily remain and clog the mesh or adhere to the belt surface. If not cleaned in time, this will obstruct hot air flow, causing uneven drying, increased energy consumption, and cross-contamination between batches, seriously affecting production efficiency and product quality.

[0003] Currently, most common cleaning devices employ a roller brush structure. This roller brush rotates in the opposite direction to the conveyor belt's movement, sweeping the conveyor belt with its bristles to remove surface deposits and clogging material within the mesh, thereby maintaining unobstructed mesh flow, preventing material mixing, and ensuring, to a certain extent, the continuous and stable operation of the equipment.

[0004] However, staff found that the above-mentioned mesh belt cleaning device still has some shortcomings: the roller brush only sweeps along the direction of mesh belt operation, the cleaning effect is concentrated in the longitudinal direction, lacks transverse sweeping force, cannot cover the inside of the mesh, and easily forms cleaning blind spots. In addition, the residue that falls off during the cleaning process is easy to fall into the inner space of the mesh belt, which is difficult to be automatically discharged, and may cause secondary accumulation or internal pollution of the equipment, requiring manual intervention to clean, which increases maintenance costs. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0006] Therefore, one objective of this utility model is to provide a belt cleaning device for a belt dryer. By driving the roller brush to rotate longitudinally and reciprocate laterally through the reciprocating mechanism in the brushing component, a multi-directional thorough cleaning of the mesh of the belt can be achieved, significantly improving the comprehensiveness and effectiveness of the cleaning. At the same time, the blowing component is linked with the reciprocating mechanism to promptly blow away and guide the cleaned residue out of the equipment, effectively avoiding secondary pollution.

[0007] To achieve the above objectives, the first aspect of this utility model provides a belt cleaning device for a belt dryer, comprising: two electric push rods, a lifting plate, a brushing assembly, and a blowing assembly. The two electric push rods are respectively fixedly installed on both sides of the belt dryer support frame. The lifting plate is fixedly installed at the bottom of the telescopic portions of the two electric push rods. The brushing assembly includes a rotating mechanism and a reciprocating mechanism, wherein the rotating mechanism and the reciprocating mechanism are respectively disposed at the top of the lifting plate, and the reciprocating mechanism is connected to the rotating mechanism. The blowing assembly includes an air jet mechanism and a guiding mechanism, wherein the air jet mechanism is disposed at the top of the lifting plate, and the air jet mechanism is connected to the reciprocating mechanism. The guiding mechanism is disposed between the lifting plate and the belt dryer support frame.

[0008] In addition, the belt cleaning device for a belt dryer proposed in this utility model may also have the following additional technical features:

[0009] Specifically, the rotating mechanism includes a drive unit, a spline shaft, a sleeve, and a roller brush. The drive unit is mounted on the top of the lifting plate, the spline shaft is rotatably mounted on the top of the lifting plate and connected to the drive unit, the sleeve is slidably mounted on the outside of the spline shaft, and the roller brush is fixedly mounted on the outside of the sleeve.

[0010] Specifically, the reciprocating mechanism includes a fixed frame, a reciprocating lead screw, a transmission part, a limiting rod, a sliding nut, and a connecting frame.

[0011] Specifically, the jet mechanism includes two jet frames and two pump units, wherein the two jet frames are respectively fixedly installed on the top of the lifting plate, the two pump units are respectively installed on one side of the two jet frames, and the two pump units are respectively connected to the connecting frame.

[0012] Specifically, the guiding mechanism includes a guiding pipe and two connecting pipes.

The two connecting pipes are respectively fixedly connected to the inside of the lifting plate, and the two connecting pipes are slidably connected to the guiding pipe.

[0013] Compared with the prior art, this utility model has the following beneficial effects: Through the synergistic effect of the reciprocating mechanism and the rotating mechanism in the brushing component, this utility model drives the roller brush to achieve lateral reciprocating motion while rotating longitudinally, breaking through the cleaning blind spots of traditional unidirectional roller brushes, realizing multi-dimensional and dead-angle cleaning of the mesh of the mesh belt, greatly improving the comprehensiveness and thoroughness of cleaning. At the same time, the innovative linkage between the blowing component and the reciprocating mechanism can quickly blow away and concentrate the detached residue in real time during the cleaning process, effectively avoiding the accumulation of impurities inside the equipment or causing secondary pollution.

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] The following description, with reference to the accompanying drawings, describes an embodiment of a belt dryer mesh belt cleaning device of the present invention.

[0023] like Figures 1-4 As shown in the figure, a belt cleaning device for a belt dryer according to an embodiment of the present invention includes: two electric push rods 1, a lifting plate 2, a brushing assembly 3, and a blowing assembly 4.

[0024] Two electric push rods 1 are fixedly installed on both sides of the belt dryer support frame, and the lifting plate 2 is fixedly installed at the bottom of the telescopic part of the two electric push rods 1.

[0025] It should be noted that the extension length of the electric push rod 1 can be locked, thereby locking the height of the lifting plate 2.

[0026] The scrubbing assembly 3 includes a rotating mechanism 31 and a reciprocating mechanism 32.

[0027] The rotating mechanism 31 and the reciprocating mechanism 32 are respectively located at the top of the lifting plate 2, and the reciprocating mechanism 32 is connected to the rotating mechanism 31.

[0028] The purging assembly 4 includes an air jet mechanism 41 and a guide mechanism 42, wherein...

[0029] The jetting mechanism 41 is located at the top of the lifting plate 2 and is connected to the reciprocating mechanism 32. The guiding mechanism 42 is located between the lifting plate 2 and the belt dryer support frame.

[0030] Specifically, this belt dryer belt cleaning device is used when staff need to clean the mesh belt of the belt dryer.

[0031] First, the staff starts the belt dryer and makes the mesh belt run at a low speed. Then, the electric push rod 1 is activated to retract, which drives the lifting plate 2 to rise. After positioning the brushing component 3 at the cleaning height, the electric push rod 1 is locked. At this time, the brushing component 3 is in contact with the mesh belt and is in the state of waiting to be cleaned.

[0032] Next, the staff started the rotating mechanism 31 inside the brushing component 3. It rotates in the opposite direction of the mesh belt, which significantly enhances the brushing efficiency by means of relative motion. At the same time as the rotating mechanism 31 is running, the connected reciprocating mechanism 32 is driven, which drives the brushing component to move laterally back and forth, thereby achieving a thorough cleaning of the mesh in multiple directions.

[0033] In addition, the reciprocating mechanism 32 works in conjunction with the jetting mechanism 41 to spray air onto the freshly cleaned mesh belt area, promptly blowing away the residue. Finally, the debris is effectively discharged from the equipment under the guidance of the guiding mechanism 42, ensuring the continuous cleanliness of the belt dryer and preventing secondary pollution.

[0034] In one embodiment of this utility model, such as Figure 4 As shown, the rotating mechanism 31 includes a drive unit 311, a splined shaft 312, a sleeve 313, and a roller brush 314.

[0035] The drive unit 311 is installed at the top of the lifting plate 2, and the spline shaft 312 is rotatably installed at the top of the lifting plate 2, and the spline shaft 312 is connected to the drive unit 311.

[0036] Specifically, the drive unit 311 includes a dual-output shaft motor mounted on the top of the lifting plate 2, two rotating shafts mounted on both sides of the dual-output shaft motor, two first sprockets mounted on the two rotating shafts, and two second sprockets mounted on both ends of the spline shaft 312. Chains are sleeved on the outer sides of the corresponding first sprockets and second sprockets.

[0037] Sleeve 313 is slidably mounted on the outside of spline shaft 312, and roller brush 314 is fixedly mounted on the outside of sleeve 313.

[0038] Specifically, when the dual-output shaft motor starts, it drives the two rotating shafts on both sides to rotate synchronously in the same direction, so that the two first sprockets drive the corresponding second sprockets to rotate synchronously through the chain, thereby causing the spline shaft 312 to rotate. The spline shaft 312 drives the outer slidingly connected sleeve 313 to rotate, so that the drum can rotate to brush the mesh belt.

[0039] In one embodiment of this utility model, such as Figure 4 As shown, the reciprocating mechanism 32 includes a fixed frame 321, a reciprocating lead screw 322, a transmission part 323, a limiting rod 324, a sliding nut 325, and a connecting frame 326.

[0040] The fixed frame 321 is fixedly installed on the top of the lifting plate 2, the reciprocating screw 322 is rotatably installed on the top of the fixed frame 321, and the transmission part 323 is arranged between the reciprocating screw 322 and the drive part 311. The transmission part 323 is connected to the reciprocating screw 322 and the drive part 311 respectively.

[0041] Specifically, the transmission unit 323 includes two third sprockets respectively installed at both ends of the reciprocating screw 322 and two fourth sprockets respectively installed on the outside of the two rotating shafts, with chains sleeved on the outside of the corresponding third sprockets and fourth sprockets.

[0042] The limiting rod 324 is fixedly installed on the top of the fixed frame 321. The sliding nut 325 is slidably connected to the outside of the limiting rod 324. The sliding nut 325 is threadedly connected to the reciprocating screw 322. The connecting frame 326 is fixedly installed on the top of the sliding nut 325. The connecting frame 326 is rotatably connected to the sleeve 313.

[0043] It should be noted that the reciprocating screw 322 is compatible with the sliding nut 325. When the reciprocating screw 322 rotates in one direction, the sliding nut 325 will move back and forth on the outside of the reciprocating screw 322 under the guidance of the two threaded grooves on the outside of the reciprocating screw 322 and under the restriction of axial rotation by the limit rod 324.

[0044] Specifically, when the drive unit 311 is started, the rotating shaft synchronously drives the fourth sprocket to rotate. Through the chain, the fourth sprocket synchronously drives the third sprocket and the reciprocating screw 322 to rotate. The reciprocating screw 322 drives the sliding nut 325 to reciprocate outside the reciprocating screw 322 and the limit rod 324, which in turn causes the connecting frame 326 to drive the sleeve 313 to reciprocate outside the spline shaft 312, so that the roller brush 314 can move laterally back and forth to brush the conveyor belt.

[0045] In one embodiment of this utility model, such as Figure 3 As shown, the jet mechanism 41 includes two jet mounts 411 and two pump pressure units 412.

[0046] Two jet mounts 411 are fixedly installed on the top of the lifting plate 2, and two pump pressure parts 412 are installed on one side of the two jet mounts 411, and the two pump pressure parts 412 are connected to the connecting frame 326 respectively.

[0047] Specifically, the jet frame 411 consists of two connecting pipes and a jet plate. The two connecting pipes are fixedly installed at the top of the lifting plate 2, and the jet plate is fixedly installed at the top of the two connecting pipes. An air storage chamber is opened inside the jet plate, and the inside of the connecting pipe is connected to the air storage chamber. The cross-section of the jet plate is triangular, which facilitates the guidance of airflow direction. Multiple jet nozzles are opened at the top of the jet plate, and the jet nozzles are directly facing the contact position of the mesh belt and the roller brush 314.

[0048] Specifically, the pump pressure section 412 includes two one-way valves, a pump pressure pipe, and a piston rod with a piston. The two one-way valves are respectively installed on the inner side of the top and the outer side of the bottom of a connecting pipe. The pump pressure pipe is installed on one side of the middle section of this connecting pipe. The piston rod with a piston is slidably connected to the inner side of the piston pipe, and the piston rod is fixedly connected to the connecting bracket 326.

[0049] It should be noted that the one-way valve installed on the outside of the bottom of the connecting pipe only allows air to enter the connecting pipe, while the one-way valve installed on the inside of the top of the connecting pipe only allows air to enter the jet plate from the connecting pipe.

[0050] The guiding mechanism 42 includes a guiding tube 421 and two connecting tubes 422.

[0051] Among them, the guide pipe 421 is fixedly installed on the inner side of the belt dryer support frame, and the bottom of the guide pipe 421 is provided with a guide groove. Two connecting pipes 422 are fixedly connected to the inner side of the lifting plate 2, and the two connecting pipes 422 are slidably connected to the guide pipe 421.

[0052] It should be noted that the two jet mounts 411 and the two pump pressure sections 412 are symmetrical about the rotation center. When one pump pressure section 412 draws in air, the other pump pressure section 412 discharges air, thus achieving alternating continuous jetting.

[0053] Specifically, when the reciprocating mechanism 32 operates, the connecting frame 326 moves back and forth, thereby driving the piston rod to slide back and forth in the pump pressure pipe. When the pump pressure pipe is under low pressure, air enters the connecting pipe and the pump pressure pipe through the one-way valve on the outside of the bottom of the connecting pipe. When the pump pressure pipe is under high pressure, air enters the air storage chamber of the jet plate through the one-way valve on the inside of the top of the connecting pipe. Because the jet nozzle at the top of the jet plate is narrow, the air can be blown more forcefully onto the mesh belt. The residue is discharged into the guide pipe 421. Because the top of the guide pipe 421 is low in the middle and high at both ends, the residue is guided to both ends of the guide pipe 421 and smoothly enters the connecting pipe 422, and is discharged to the bottom of the belt dryer, waiting for the staff to collect and clean it.

[0054] In summary, the belt cleaning device for the belt dryer of this utility model controls the lifting and precise positioning of the brushing component 3 through the electric push rod 1, and drives the roller brush 314 to rotate in the opposite direction of the belt to improve the brushing intensity. At the same time, the reciprocating mechanism 32 drives the roller brush 314 to move laterally, so as to achieve multi-directional and dead-angle cleaning of the mesh. The device also links the reciprocating motion with the blowing function. During the brushing process, the pump pressure mechanism generates directional airflow to blow the residue away from the mesh surface in time, and discharge it out of the machine through the guide pipe 421, effectively preventing blockage and secondary pollution.
