Description

Technical Field

[0001] The utility model relates to the technical field of leaf threshing and redrying equipment, in particular to an online cleaning device for a mesh belt of a redrying machine. Background Art

[0002] In the process of using a re-drying machine to re-dry tobacco leaves or stems, the mesh belt used to transport tobacco leaves or stems will gradually be adhered to tobacco oil and soot. If these soot adhered to the mesh belt are not cleaned in time, there is a risk of falling into the material, resulting in quality accidents. Moreover, the long-term accumulation of tobacco oil and soot will block the mesh holes on the mesh belt, which will lead to a decrease in the uniform ventilation efficiency of the mesh belt, uneven heating of the material, and uneven moisture content of the material after roasting, affecting the re-drying quality of tobacco leaves or stems. At the same time, if the soot accumulates seriously on the mesh belt, it will also affect the normal operation of the mesh belt, causing abnormal noise or damage to the re-drying belt, and even causing the re-drying machine to malfunction and shut down, affecting production. Therefore, it is very important to clean the tobacco oil and soot adhered to the mesh belt in time.

[0003] At present, the mesh belt of the re-drying machine is generally cleaned and descaled manually. However, the leaf threshing and re-drying production line generally adopts a maintenance mode of continuous production for half a month and then shuts down for two days for equipment maintenance. Due to the large number of mesh holes on the mesh belt, manual cleaning is labor-intensive and work efficiency is low. In a short downtime, the cleaning is not thorough, and the manual use of steel brushes and steel shovels to remove smoke scales will also damage the mesh belt.

[0004] In addition, in order to improve work efficiency and cleaning effect, some leaf threshing and re-drying companies use automatic cleaning methods such as high-pressure water or high-pressure steam. However, since the smoke scale is severely adhered and difficult to remove, it is often necessary to spray the mesh belt for a long time, which consumes a large amount of water or steam. Not only will a large amount of wastewater be discharged later, causing secondary pollution, but it is also impossible to achieve online cleaning of the mesh belt during the production process.

[0039] In addition, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0040] See also Figure 1 , Figure 3 and Figure 4The present embodiment provides an online cleaning device for a re-roasting machine mesh belt, comprising an electric frame 1, a soot collecting box 2, a dry ice cleaning machine 3 and a vacuum cleaner 4. The electric frame 1 is provided with an upper reciprocating and transverse track 11 and a lower reciprocating and transverse track 12 at intervals in the vertical direction. An accommodating space 13 is provided between the upper reciprocating and transverse track 11 and the lower reciprocating and transverse track 12, and the upper reciprocating and transverse track 11 and the lower reciprocating and transverse track 12 are parallel to each other. The soot collecting box 2 has an opening at the top and is vertically installed on the lower reciprocating and transverse track 12. The cleaning nozzle 31 on the dry ice cleaning machine 3 is installed in the top opening of the soot collecting box 2 and is vertically arranged upward. The vacuum nozzle 41 on the vacuum cleaner 4 is installed on the upper reciprocating and transverse track 11 and is vertically arranged downward. The cleaning nozzle 31 and the vacuum nozzle 41 are relatively arranged at intervals and move synchronously.

[0041] When in use, the online cleaning device for the mesh belt of the re-roasting machine of this embodiment can be directly arranged at the mesh belt position near the discharge end of the re-roasting machine, so that the mesh belt 5 is located in the accommodating space 13 and the mesh belt plate 51 is parallel to the upper reciprocating transverse track 11, the upper reciprocating transverse track 11 is located above the mesh belt 5, and the lower reciprocating transverse track 12 is located below the mesh belt 5, and then the cleaning nozzle 31 and the dust suction nozzle 41 are synchronously moved on the corresponding reciprocating transverse track by controlling the electric frame 1, and the dry ice cleaning machine 3, the vacuum cleaner 4 and the re-roasting machine are turned on, and the dry ice cleaning machine 3 cleans the mesh belt of the re-roasting machine, and a part of the cleaned soot falls into the soot collection box 2 from below, and the other part is sucked into the vacuum cleaner 4, thereby realizing online automatic cleaning of the mesh belt of the re-roasting machine with high efficiency.

[0042] It should be noted that since the cleaning nozzle 31 is below the mesh belt 5, it is responsible for cleaning the working surface of the mesh belt plate 51; the soot collection box 2 is located below the mesh belt 5, so it is used to collect dirt fallen from the working surface of the mesh belt plate 51; and the dust suction nozzle 41 is located above the mesh belt 5, so it is responsible for sucking away the dirt blown from the mesh holes to the other side of the mesh belt plate 51.

[0043] Preferably, see Figure 2 The electric frame 1 includes a left support frame 14 and a right support frame 15, which are laterally spaced apart. The upper reciprocating transverse track 11 is detachably mounted on the left support frame 14 and the right support frame 15, and the lower reciprocating transverse track 12 is detachably mounted on the left support frame 14 and the right support frame 15.

[0044] When it is necessary to arrange the online cleaning device of the mesh belt of the re-roasting machine of the present embodiment at the mesh belt position near the discharge end of the re-roasting machine, first push the left support frame 14 to the left side of the mesh belt of the discharge end of the re-roasting machine, and push the right support frame 15 to the right side of the mesh belt of the discharge end of the re-roasting machine, and make the two support frames symmetrically arranged on both sides of the mesh belt 5, and then install the upper reciprocating transverse movement track 11 and the lower reciprocating transverse movement track 12 on the left support frame 14 and the right support frame 15. The detachable split structure of the electric frame 1 makes it easier for the electric frame 1 to move its position, which helps to arrange the online cleaning device of the mesh belt of the re-roasting machine of the present embodiment to the mesh belt position near the discharge end of the re-roasting machine.

[0045] In addition, when the online cleaning device for the mesh belt of the re-roasting machine of this embodiment is in use, the dry ice cleaning machine 3 is pushed to the side of the right support frame 15 and connected to power and compressed air, and the vacuum cleaner 4 is pushed to the side of the right support frame 15 and connected to power.

[0046] Preferably, movable casters and feet are installed at the bottom of the left support frame 14 and the bottom of the right support frame 15. The movable casters are in contact with the ground, and the feet are suspended and height-adjustable. When the left support frame 14 and the right support frame 15 are pushed to move on the ground, the feet are in a suspended state, and the movable casters are in contact with the ground to reduce friction, making the pushing process more labor-saving; and when the left support frame 14 and the right support frame 15 are pushed to the specified position, the height of the feet is adjusted so that the feet are supported on the ground, and the movable casters are in a suspended state, so as to fix the left support frame 14 and the right support frame 15.

[0047] Preferably, see Figure 2 and Figure 3 An upper driving unit 111 and an upper slider seat 112 are installed on the upper reciprocating transverse track 11. The upper driving unit 111 drives the upper slider seat 112 to reciprocate along the length direction of the upper reciprocating transverse track 11. The dust nozzle 41 is adjustably arranged on the dust nozzle bracket 42, and the dust nozzle bracket 42 is fixedly connected to the upper slider seat 112.

[0048] It should be noted that, in order to ensure the effect of removing smoke stains, the online cleaning device for the mesh belt of the re-roasting machine of this embodiment should make the suction nozzle 41 as close to the mesh belt plate surface of the re-roasting machine as possible when in use.

[0049] Preferably, see Figure 2 and Figure 3 A lower driving unit 121 and a lower slider seat 122 are installed on the lower reciprocating transverse track 12. The lower driving unit 121 drives the lower slider seat 122 to reciprocate along the length direction of the lower reciprocating transverse track 12. The soot collection box 2 is installed on the lower slider seat 122. The cleaning nozzle 31 is adjustably arranged on the cleaning nozzle bracket 32. The cleaning nozzle bracket 32 ​​is fixedly connected to the soot collection box 2.

[0050] It should be noted that, in order to ensure the cleaning effect, the online cleaning device for the mesh belt of the re-roasting machine of this embodiment should keep the distance between the cleaning nozzle 31 and the mesh belt of the re-roasting machine at 50 mm when in use.

[0051] Preferably, in this embodiment, the upper driving unit 111 and the lower driving unit 121 are both driving motors, and drive the upper slider seat 112 and the lower slider seat 122 to reciprocate along the length direction through belt transmission or gear transmission.

[0052] Preferably, see Figure 1 and Figure 2 A controller 6 is provided on the electric frame 1, and positioning sensors are provided at both ends of the length direction of the upper reciprocating and transverse moving track 11 and the lower reciprocating and transverse moving track 12. The upper reciprocating and transverse moving track 11, the lower reciprocating and transverse moving track 12 and the positioning sensors are all connected to the controller 6 signals.

[0053] The setting of the controller 6 can not only keep the cleaning nozzle 31 and the dust suction nozzle 41 moving synchronously, but also directly control the moving speed of the upper reciprocating and transverse moving track 11 and the lower reciprocating and transverse moving track 12 according to the cleaning degree requirements, so as to ensure that the mesh belt 5 is thoroughly cleaned.

[0054] In addition, the controller 6 can also adjust the movement direction through the positioning sensor. When the cleaning nozzle 31 and the dust nozzle 41 move synchronously to the left end extreme position, the positioning sensor at the left end detects that the cleaning nozzle 31 or the dust nozzle 41 is in place. After receiving the in-place signal from the positioning sensor, the controller 6 sends a reverse motion execution information to the upper reciprocating transverse track 11 and the lower reciprocating transverse track 12, thereby driving the cleaning nozzle 31 and the dust nozzle 41 to move in the opposite direction synchronously; when reaching the right end extreme position, the positioning sensor at the right end sends an in-place signal to the controller 6, and the controller 6 controls the upper reciprocating transverse track 11 and the lower reciprocating transverse track 12 to execute the reverse motion again, so that the cleaning nozzle 31 and the dust nozzle 41 move in the opposite direction synchronously again, thereby realizing the cyclic reciprocating motion.

[0055] It should be noted that, in the present embodiment, the cleaning width of the cleaning nozzle 31 is preferably 30 mm. Since the reciprocating motion of the cleaning nozzle 31 and the movement of the re-roasting machine mesh belt itself will form a 30 mm wide triangular waveform cleaning path, the re-roasting machine mesh belt needs to adjust the cleaning starting point of the cleaning nozzle 31 after one circle operation of the re-roasting machine mesh belt to ensure that the cleaning paths do not overlap after each circle operation of the re-roasting machine mesh belt, and this cycle is repeated until the re-roasting machine mesh belt is completely cleaned.

[0056] In addition, the cleaning nozzle 31 and the dust nozzle 41 have another action mode, in which the controller 6 controls the cleaning nozzle 31 and the dust nozzle 41 to move synchronously to the starting position on one side of the re-roasting machine mesh belt and remain stationary, start cleaning, and adjust the dry ice spray flow of the dry ice cleaning machine 3 to ensure that the mesh belt 5 is thoroughly cleaned. After the re-roasting machine mesh belt runs in a circle for one week, a 30mm wide cleaning path in the length direction of the mesh belt is completed, and then the cleaning nozzle 31 and the dust nozzle 41 are controlled to move synchronously to the other side by 30mm, that is, step by the cleaning width distance of a cleaning nozzle 31, and continue to maintain a stationary state to perform cleaning. After the re-roasting machine mesh belt runs in a circle for one week, the cleaning nozzle 31 and the dust nozzle 41 continue to be moved synchronously and cleaned in a stationary state until the re-roasting machine mesh belt is completely cleaned.

[0057] Preferably, see Figure 4 The soot collecting box 2 is provided with an ash drawer 21 and movable casters. The ash drawer 21 is located near the bottom of the soot collecting box 2, and the ash drawer 21 is detachably arranged inside the soot collecting box 2. The movable casters are installed at the bottom of the soot collecting box 2 and are in contact with the ground.

[0058] The arrangement of the movable casters can facilitate the reciprocating movement of the soot collection box 2 driven by the lower reciprocating horizontal track 12, and the ash drawer 21 can enable the online cleaning device of the mesh belt of the re-roasting machine of this embodiment to clean the soot collected in the soot collection box 2 by pulling out the ash drawer 21 after a period of cleaning work.

[0059] Preferably, see Figure 2 and Figure 3 The lower reciprocating traverse track 12 is provided with a lower drag chain 123, and the dry ice delivery pipe 33 extending from the dry ice cleaning machine 3 is arranged in the lower drag chain 123, and the end of the dry ice delivery pipe 33 is connected with the cleaning nozzle 31. The dry ice delivery pipe 33 is arranged in the lower drag chain 123, which can protect the dry ice delivery pipe 33 on the one hand, and can move with the cleaning nozzle 31 without hindrance on the other hand, so that the cleaning nozzle 31 is more convenient to adjust its position. When working, the dry ice cleaning machine 3 delivers dry ice to the cleaning nozzle 31 through the dry ice delivery pipe 33 by means of compressed air injection, and sprays it onto the surface of the mesh belt plate 51 through the cleaning nozzle 31, so as to realize the spray cleaning of the mesh belt of the re-baking machine.

[0060] Preferably, see Figure 2 and Figure 3An upper drag chain 113 is installed on the upper reciprocating traverse track 11, and a dust suction pipe 43 extending from the dust collector 4 is arranged in the upper drag chain 113, and the end of the dust suction pipe 43 is connected with the dust suction nozzle 41. The dust suction pipe 43 is arranged in the upper drag chain 113, which can protect the dust suction pipe 43 on the one hand, and also enable the dust suction pipe 43 to move with the dust suction nozzle 41 without hindrance, so that the dust suction nozzle 41 is more convenient to adjust its position.

[0061] To sum up, the online cleaning device for the mesh belt of the redrying machine in this embodiment is automatic and efficient, and can achieve thorough cleaning of the mesh belt of the redrying machine without stopping the machine or production, thereby ensuring the uniform ventilation efficiency of the mesh belt 5 and effectively improving the redrying quality of tobacco leaves or tobacco stems by the redrying machine; at the same time, the device uses environmentally friendly dry ice as a cleaning medium, has no pollution emissions during the cleaning process, does not damage the mesh belt 5, and is independently arranged outside the redrying machine, so it is easy to install and operate.

[0062] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
