Description

Technical Field

[0001] This invention relates to the field of material conveying technology, and in particular to a bulk material conveying device that is easy to repair. Background Technology

[0002] Air conveying chutes are common bulk material conveying devices, mainly used for conveying powdery materials such as cement and fly ash. An air conveying chute primarily consists of a chute body and a permeable fabric installed within the chute body. The permeable fabric divides the chute body into a material conveying channel and an air supply channel located below the material conveying channel. The material conveying channel has an inlet at the top of its inclined direction and an outlet at the bottom of its inclined direction. The air supply channel is connected to a blower. In operation, material is loaded through the inlet, and the blower sends air into the air supply channel. The air passes through the permeable fabric, keeping the material in the conveying channel fluidized, thus facilitating material transport.

[0003] While existing air conveying chutes can transport bulk materials, they have the following drawbacks: during use, the breathable cloth is prone to clogging or damage. Since the breathable cloth is installed inside the chute body, cleaning, repairing, or replacing the breathable cloth is troublesome, time-consuming, and labor-intensive. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a bulk material conveying device that is easy to repair, and when maintenance such as cleaning, repairing or replacing the breathable fabric is required, the operation is simple, time-saving and labor-saving.

[0005] According to an embodiment of the present invention, a maintenance-friendly bulk material conveying device includes a chute body, a breathable fabric cover, and a traction rope. The chute body includes an upper chute body with an opening at the bottom and a lower chute body with an opening at the top. The bottom end of the outer wall of the upper chute body is provided with a first flange, and the top end of the outer wall of the lower chute body is provided with a second flange. A bolt is installed between the first flange and the second flange, and a nut is fitted onto the bolt. One end of the upper chute body is provided with a feed inlet, and the other end is provided with a discharge outlet. A fan is connected to the lower chute body, and the breathable fabric cover is clamped within... The upper trough and the lower trough together form a material conveying channel, and the breathable cloth and the upper trough together form an air supply channel. The traction rope is connected to one end of the breathable cloth. When the nut on the bolt is loosened and the lower trough and the upper trough are separated, the breathable cloth can be moved out from the end of the inclined trough body away from the traction rope. After the breathable cloth is moved out, the traction rope extends out from the end of the inclined trough body away from the breathable cloth.

[0006] The easily repairable bulk material conveying device according to embodiments of the present invention has at least the following beneficial effects:

[0007] The chute body is generally inclined, with the feed inlet located at the upper end of the inclined direction and the discharge outlet located at the lower end. In use, bulk materials are poured in through the feed inlet, while a blower simultaneously supplies air into the air delivery channel. The air passes through the breathable fabric, keeping the material in the conveying channel fluidized, thus facilitating material transport. When cleaning, repairing, or replacing the breathable fabric, slightly loosen the nuts on the bolts. The lower trough body will separate from the upper trough body under its own weight, thus releasing the breathable fabric from its grip. Then, pull the end of the breathable fabric away from the traction rope to move it out of the inclined trough body. This allows for cleaning, repairing, or replacing the breathable fabric. After the breathable fabric is removed from the inclined trough body, part of the traction rope is located between the upper and lower trough bodies, while the other part remains outside the end of the inclined trough body away from the breathable fabric. After maintenance, pull the end of the traction rope outside the inclined trough body to move the maintained breathable fabric back between the upper and lower trough bodies. Finally, tighten the nuts to seal the upper and lower trough bodies, clamping the breathable fabric between them for reinstallation. This operation is convenient, time-saving, and labor-saving.

[0008] According to some embodiments of the present invention, the traction rope is detachably connected to the breathable fabric.

[0009] According to some embodiments of the present invention, a first take-up roller is provided at one end of the inclined chute body away from the traction rope. The first take-up roller extends along the width direction of the inclined chute body and is wound with a connecting rope. The connecting rope is detachably connected to the end of the breathable fabric away from the traction rope. The first take-up roller is used to take up the breathable fabric.

[0010] According to some embodiments of the present invention, both ends of the breathable fabric are provided with a first snap-fit ​​portion, the traction rope is provided with a corresponding second snap-fit ​​portion, and the connecting rope is provided with a corresponding third snap-fit ​​portion. Both the second snap-fit ​​portion and the third snap-fit ​​portion can snap-fit ​​with the corresponding first snap-fit ​​portion.

[0011] According to some embodiments of the present invention, a fourth locking portion is provided at one end of the inclined groove body away from the traction rope. After the breathable cloth moves out from the end of the inclined groove body away from the traction rope and the second locking portion separates from the corresponding first locking portion, the second locking portion can lock with the fourth locking portion.

[0012] According to some embodiments of the present invention, two mounting seats are arranged side by side at one end of the inclined chute body away from the traction rope. The mounting seats are provided with mounting grooves with top openings. Rubber interlayers are provided on both sides of the mounting grooves. Mounting shafts are provided at both ends of the first take-up roller. The two mounting shafts are respectively installed in the two mounting grooves and can be removed from the top of the mounting grooves. The rubber interlayers elastically abut against the mounting shafts.

[0013] According to some embodiments of the present invention, there are two traction ropes, which are respectively connected to both sides of the breathable fabric in the width direction. A second take-up roller is provided at one end of the inclined groove body near the traction rope. The second take-up roller extends along the width direction of the inclined groove body and has two take-up grooves along the axial direction. The positions of the two take-up grooves correspond to the positions where the two traction ropes are connected to the breathable fabric in the width direction of the inclined groove body. The two traction ropes are respectively wound into the two take-up grooves.

[0014] According to some embodiments of the present invention, a driving mechanism is provided between the upper groove and the lower groove, the driving mechanism being used to control the upper groove and the lower groove to move away from or closer to each other when the nut on the bolt is loosened.

[0015] According to some embodiments of the present invention, one of the top surface of the lower groove and the bottom surface of the upper groove is provided with a recess, and the other is provided with a protrusion. The protrusion is inserted into the recess, and the breathable fabric is held between the protrusion and the recess.

[0016] According to some embodiments of the present invention, one end of the upper trough body forms the discharge port, and a pressure strip is provided at the bottom of the upper trough body near the discharge port. The pressure strip extends along the width direction of the upper trough body, and the upper end face of the pressure strip is flush with the bottom surface of the upper trough body. The end of the breathable cloth near the discharge port is clamped between the pressure strip and the lower trough body.

[0017] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0036] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0037] The following is for reference. Figures 1 to 9 A maintenance-friendly bulk material conveying device according to an embodiment of the present invention is described.

[0038] like Figures 1 to 8 As shown, the easily repairable bulk material conveying device according to an embodiment of the present invention includes a chute body 100, a breathable cloth 200 and a traction rope 300.

[0039] For example, the inclined chute body 100 includes an upper chute body 101 and a lower chute body 102. The bottom end of the upper chute body 101 is open. One end of the upper chute body 101 is provided with a feed inlet 107 and the other end is provided with a discharge outlet 108. When the inclined chute body 100 is installed at an inclination, the feed inlet 107 is located at the upper end of the upper chute body 101 in the inclination direction. Specifically, the feed inlet 107 can be located at the top of the upper end of the upper chute body 101 in the inclination direction. The feed inlet 107 can be connected to a hopper 125. The discharge outlet 108 is located at the lower end of the upper chute body 101 in the inclination direction to facilitate the smooth conveying of bulk materials. The bottom end of the outer wall of the upper tank 101 is provided with a first flange 103. Specifically, the first flange 103 can be located on the outer walls of both sides of the upper tank 101. The first flange 103 can have multiple through first mounting holes along its length. The lower tank 102 is located below the upper tank 101. The top end of the lower tank 102 is open. The lower tank 102 is connected to a fan 109, which is used to deliver air into the lower tank 102. The top end of the outer wall of the lower tank 102 is provided with a second flange 104. Specifically, the second flange 104 can be located on both sides of the lower tank 102. On the outer side wall, the second flange 104 may be provided with a plurality of second mounting holes that pass through vertically along the length direction. The first mounting hole and the second mounting hole correspond one-to-one and are aligned. A bolt 105 is installed between the first flange 103 and the second flange 104. Specifically, the bolt 105 is inserted into the first mounting hole and the corresponding second mounting hole. The bolt 105 is fitted with a nut 106. When the nut 106 is loosened, the upper groove 101 and the lower groove 102 can be separated. When the nut 106 is tightened, the upper groove 101 and the lower groove 102 can be connected.

[0040] The breathable fabric 200 is sandwiched between the upper tank 101 and the lower tank 102. The breathable fabric 200 and the upper tank 101 enclose a material conveying channel 110, which is connected to the inlet 107 and the outlet 108. The breathable fabric 200 and the lower tank 102 enclose an air supply channel 111, which is connected to the fan 109.

[0041] The traction rope 300 can be one, two, or more, and the traction rope 300 is connected to one end of the breathable fabric 200 along its length.

[0042] When the nut 106 on the bolt 105 loosens and the lower trough 102 separates from the upper trough 101, the breathable cloth 200 can be moved out from the end of the inclined trough body 100 away from the traction rope 300, and after the breathable cloth 200 is moved out, part of the traction rope 300 extends out from the end of the inclined trough body 100 away from the breathable cloth 200.

[0043] In this embodiment, when using a bulk material conveying device, bulk materials are poured in through the inlet 107, while the blower 109 delivers air into the air supply channel 111. The air passing through the breathable cloth 200 keeps the material in the conveying channel 110 fluidized, facilitating material transport. When cleaning, repairing, or replacing the breathable cloth 200 is required, slightly loosening the nut 106 on the bolt 105 allows the lower trough 102 to separate from the upper trough 101 under its own weight, releasing the clamping of the breathable cloth 200. Then, the end of the breathable cloth 200 away from the traction rope 300 can be pulled, allowing it to move out of the inclined trough body 100 away from the traction rope 300. This allows for cleaning, repairing, or replacing the breathable cloth 200. Since after the breathable cloth 200 is removed from the inclined trough body 100, part of the traction rope 300 is located between the upper trough 101 and the lower trough 102. Between the upper and lower troughs 101 and 102, the other part of the traction rope 300 is still outside the end of the inclined trough body 100 away from the breathable cloth 200. After the breathable cloth 200 is maintained, the end of the traction rope 300 outside the inclined trough body 100 can be pulled. The traction rope 300 will then move the maintained breathable cloth 200 back between the upper trough 101 and 102. Finally, tighten the nut 106 to seal the connection between the upper trough 101 and 102. The breathable cloth 200 can then be clamped between the upper trough 101 and 102, thus realizing the reinstallation of the breathable cloth 200. The operation is convenient, time-saving and labor-saving.

[0044] It should be noted that in this invention, when cleaning, repairing, or replacing the breathable fabric 200, it is not necessary to completely unscrew the nut 106. Slightly loosening the nut 106 allows the lower groove 102 to separate slightly from the upper groove 101, enabling the breathable fabric 200 to be removed. The lower groove 102 does not need to be completely removed. Therefore, when the breathable fabric 200 is reinstalled, only the nut 106 needs to be tightened; the lower groove 102 does not need to be reinstalled, making the operation very convenient, time-saving, and labor-saving. Furthermore, since a traction rope 300 is provided, when the breathable fabric 200 needs to be removed and reinstalled, simply pulling the traction rope 300 is sufficient, making the operation very convenient, time-saving, and labor-saving.

[0045] In some embodiments of the present invention, such as Figure 4 , Figure 5 and Figure 7 As shown, the traction rope 300 and the breathable cloth 200 are detachably connected. With this configuration, when the breathable cloth 200 is removed from the inclined chute body 100, the traction rope 300 can be separated from the breathable cloth 200, which makes it easier to send the breathable cloth 200 to cleaning equipment and maintenance equipment for cleaning and maintenance, and also makes it easier to replace the breathable cloth 200.

[0046] In some embodiments of the present invention, such as Figure 8 As shown, a first take-up roller 112 is provided at the end of the inclined chute body 100 away from the traction rope 300. The first take-up roller 112 extends along the width direction of the inclined chute body 100, and a connecting rope 113 is wound around the first take-up roller 112. The connecting rope 113 is detachably connected to the end of the breathable fabric 200 away from the traction rope 300. The first take-up roller 112 is used to take up the breathable fabric 200. Since the breathable fabric 200 is large, it is very inconvenient to handle it directly. In this embodiment, the first take-up roller 112 is provided. After the breathable fabric 200 is moved out of the inclined chute body 100, the first take-up roller 112 can be rotated. The first take-up roller 112 can drive the breathable fabric 200 to be wound onto the first take-up roller 112 through the connecting rope 113, thereby making it more convenient to handle the breathable fabric 200. The connecting rope 113 is detachably connected to the end of the breathable cloth 200 away from the traction rope 300. Therefore, when the breathable cloth 200 needs to be cleaned, repaired or replaced after being moved to the required position, the breathable cloth 200 can be detached from the connecting rope 113, making it more convenient to clean, repair or replace the breathable cloth 200.

[0047] In some embodiments of the present invention, such as Figure 5 and Figure 8 As shown, both ends of the breathable fabric 200 are provided with a first engaging portion 201, the traction rope 300 is provided with a corresponding second engaging portion 301, and the connecting rope 113 is provided with a corresponding third engaging portion 114. Both the second engaging portion 301 and the third engaging portion 114 can engage with their corresponding first engaging portions 201. Engaging the second engaging portion 301 with its corresponding first engaging portion 201 connects the traction rope 300 to the breathable fabric 200; disengaging the second engaging portion 301 from its corresponding first engaging portion 201 separates the traction rope 300 from the breathable fabric 200. Similarly, engaging the third engaging portion 114 with its corresponding first engaging portion 201 connects the connecting rope 113 to the breathable fabric 200; disengaging the third engaging portion 114 from its corresponding first engaging portion 201 separates the connecting rope 113 from the breathable fabric 200. The structure is simple and the operation is convenient.

[0048] It should be noted that the traction rope 300 and the breathable cloth 200 can also be detachably connected in other ways, and the connecting rope 113 and the breathable cloth 200 can also be detachably connected in other ways. For example, connecting parts can be provided at both ends of the breathable cloth 200, and threaded holes can be provided at the connecting parts. Screws can be installed on the traction rope 300 and the connecting rope 113. The detachable connection between the traction rope 300 and the breathable cloth 200 and the connecting rope 113 can be achieved by connecting the screws with the threaded connection of the connecting parts.

[0049] It is understandable that the structures of the first engaging portion 201, the second engaging portion 301, and the third engaging portion 114 can be varied. For example, the first engaging portion 201 can be a retaining ring, and the second engaging portion 301 and the third engaging portion 114 can be elastic retaining beads. The elastic retaining beads can be engaged into or disengaged from the retaining ring through elastic deformation. Of course, the first engaging portion 201 can also be an elastic retaining bead, and the second engaging portion 301 and the third engaging portion 114 can be a retaining ring. In addition, the first engaging portion 201, the second engaging portion 301, and the third engaging portion 114 can also be other common engaging structures, which will not be elaborated here.

[0050] In some embodiments of the present invention, such as Figure 8 As shown, the inclined chute body 100 has a fourth locking part 115 at the end away from the traction rope 300. After the breathable cloth 200 moves out from the end of the inclined chute body 100 away from the traction rope 300, and the second locking part 301 separates from the corresponding first locking part 201, the second locking part 301 can engage with the fourth locking part 115. In this embodiment, when the breathable cloth 200 moves out from the end of the inclined chute body 100 away from the traction rope 300, and the second locking part 301 separates from the corresponding first locking part 201, the second locking part 301 on the traction rope 300 engages with the third locking part 114 on the inclined chute body 100. This prevents the traction rope 300 between the upper chute body 101 and the lower chute body 102 from sliding out from the end of the inclined chute body 100 away from the breathable cloth 200, which would make it inconvenient to connect the traction rope 300 to the breathable cloth 200 when reinstalling it.

[0051] It should be noted that the fourth locking part 115 can also be a retaining ring or a flexible retaining bead.

[0052] In some embodiments of the present invention, such as Figure 8As shown, two mounting seats 116 are arranged side by side at one end of the inclined chute body 100 away from the traction rope 300. The mounting seats 116 have mounting grooves 117 with openings at the top. Rubber interlayers 118 are provided on both sides of the mounting grooves 117. The two ends of the first take-up roller 112 are provided with mounting shafts 119. The two mounting shafts 119 are respectively installed in the two mounting grooves 117 and can be removed from the top of the mounting grooves 117. The rubber interlayers 118 elastically abut against the mounting shafts 119. When the breathable cloth 200 is wound onto the first take-up roller 112, the first take-up roller 112 can be removed by moving it upwards. When the first take-up roller 112 needs to be reinstalled, the mounting shafts 119 at both ends of the first take-up roller 112 are positioned directly above the mounting grooves 117, and then the first take-up roller 112 is moved downwards. The operation is simple and convenient, saving time and effort. Rubber interlayers 118 are provided on both sides of the mounting groove 117. After the mounting shaft 119 is installed in the mounting groove 117, the rubber interlayers 118 elastically abut against the mounting shaft 119. That is, the rubber interlayers 118 on both sides of the mounting groove 117 elastically clamp the mounting shaft 119, thereby preventing the first take-up roller 112 from moving out of the top of the mounting groove 117 at will, making the installation more stable.

[0053] In some embodiments of the present invention, such as Figure 4 , Figure 5 , Figure 7 and Figure 9 As shown, there are two traction ropes 300, which are respectively connected to both sides of the breathable fabric 200 in the width direction. The inclined chute body 100 is provided with a second take-up roller 120 near the end of the traction rope 300. The second take-up roller 120 extends along the width direction of the inclined chute body 100 and is provided with two take-up grooves 121 along the axial direction. Along the width direction of the inclined chute body 100, the positions of the two take-up grooves 121 correspond to the positions where the two traction ropes 300 are connected to the breathable fabric 200. The two traction ropes 300 are respectively wound into the two take-up grooves 121. Along the width direction of the inclined chute body 100, the positions of the two winding grooves 121 correspond to the positions where the two traction ropes 300 are connected to the breathable cloth 200. That is, along the projection of the length direction of the inclined chute body 100, the positions of the winding grooves 121 and the corresponding positions where the traction ropes 300 are connected to the breathable cloth 200 are approximately on the same vertical plane. Therefore, when the traction ropes 300 move the breathable cloth 200 to reinstall the breathable cloth 200, the breathable cloth 200 can be prevented from moving arbitrarily along the width direction. This not only makes the reinstallation of the breathable cloth 200 more accurate, but also prevents the breathable cloth 200 from getting stuck when moving.

[0054] In some embodiments of the present invention, such as Figures 1 to 2As shown, a drive mechanism 400 is provided between the upper groove 101 and the lower groove 102. The drive mechanism 400 is used to control the upper groove 101 and the lower groove 102 to move away from or closer to each other when the nut 106 on the bolt 105 is loosened. For example, the drive mechanism 400 can be a hydraulic cylinder located on both sides of the upper groove 101. The hydraulic cylinder extends along the thickness direction of the inclined groove body 100, and the piston rod of the hydraulic cylinder has a connecting seat at its end, which is connected to the lower groove 102. When the nut 106 on the bolt 105 is loosened, the upper groove 101 and the lower groove 102 can be controlled to move away from or closer to each other by extending and retracting the hydraulic cylinder, without the need for manual movement of the lower groove 102. This makes the operation more convenient, saves more time and effort, and allows for more precise control of the relative movement distance between the upper groove 101 and the lower groove 102.

[0055] It should be noted that when the lower groove 102 and the upper groove 101 move relative to each other, the bolt 105 also provides a guiding function to prevent the lower groove 102 and the upper groove 101 from shifting laterally in the horizontal direction, thereby making the relative movement of the lower groove 102 and the upper groove 101 more precise. In addition, the drive mechanism 400 can also be other structures, such as a motor lead screw mechanism.

[0056] In some embodiments of the present invention, such as Figures 6 to 8 As shown, one of the top surface of the lower tank 102 and the bottom surface of the upper tank 101 has a recess 122, and the other has a protrusion 123. The protrusion 123 is inserted into the recess 122, and the breathable fabric 200 is sandwiched between the protrusion 123 and the recess 122. For example, the top surface of the side wall of the lower tank 102 may have a recess 122, and the bottom surface of the side wall of the upper tank 101 may have a protrusion 123, or the top surface of the side wall of the lower tank 102 may have a protrusion 123, and the bottom surface of the side wall of the upper tank 101 may have a recess 122, with the edge of the breathable fabric 200 sandwiched between the protrusion 123 and the recess 122. This design not only makes the installation of the breathable cloth 200 more stable, but also improves the sealing between the breathable cloth 200 and the upper trough 101 and the lower trough 102. This prevents air in the air supply channel 111 from flowing out through the gap between the top surface of the breathable cloth 200 and the lower trough 102, allowing more air to pass through the breathable cloth 200 and flow into the material conveying channel 110. In addition, it also prevents material in the material conveying channel 110 from flowing out through the gap between the breathable cloth 200 and the bottom surface of the upper trough 101, thus improving the material conveying effect.

[0057] It should be noted that both the concave part 122 and the convex part 123 can be arc-shaped, which not only makes the breathable fabric 200 more effective in clamping, but also makes it easier for the convex part 123 and the concave part 122 to engage and disengage, thus improving practicality.

[0058] In some embodiments of the present invention, such as Figure 3 and Figure 8 As shown, one end of the upper trough 101 forms a discharge port 108. A pressure strip 124 is provided at the bottom of the end of the upper trough 101 near the discharge port 108. The pressure strip 124 extends along the width direction of the upper trough 101, and its upper surface is flush with the bottom surface of the upper trough 101. The end of the breathable cloth 200 near the discharge port 108 is clamped between the pressure strip 124 and the lower trough 102. The pressure strip 124, through its engagement with the upper surface of the lower trough 102, clamps the end of the breathable cloth 200 near the discharge port 108, thus making the installation of the end of the breathable cloth 200 near the discharge port 108 more stable and improving the sealing performance of that end. The upper end face of the pressure strip 124 is flush with the bottom surface of the upper trough 101. After clamping the breathable cloth 200, the upper end face of the portion of the breathable cloth 200 between the air supply channel 111 and the material conveying channel 110 is flush with the upper end face of the pressure strip 124. This avoids the presence of the pressure strip 124 from obstructing the material conveying and makes the material conveying effect better.
