Abstract
Description
Technical Field
[0001] This utility model relates to the field of dehumidification screen cleaning technology, and in particular to a cleaning device. Background Technology
[0002] Typically, the dehumidification screen in a tobacco stem rehumidifier is used to filter out excess steam generated during tobacco stem processing. This screen requires regular cleaning because if it becomes clogged, the steam can only be absorbed and carried away by the tobacco stem material. However, during the preheating stage of production, the rehumidification drum needs to reach the set preheating temperature. If there is no material to absorb the excess steam, the steam inside the drum cannot be effectively discharged and will escape to both ends, forming a large amount of condensate at the front and rear ends. This results in steam overflow, ultimately causing the material's moisture content and temperature to fail to meet the requirements of the tobacco stem production process. It can also lead to water accumulation on-site and pose a risk of water ingress and electrical leakage to electrical equipment.
[0003] When cleaning dehumidification screens, only a portion of the openings in cylindrical equipment such as wire rehumidifiers is opened, leaving only a part of the screen exposed. This makes it difficult for existing brush cleaning devices to clean the hidden internal parts of the screen. Furthermore, due to the narrow openings, the brush cleaning devices are relatively short in length to facilitate their passage and approach the screen, resulting in a small cleaning surface and low cleaning efficiency. Therefore, there is an urgent need for a cleaning device to solve these problems. Utility Model Content

[0029] This embodiment provides a cleaning device in which the second brush assembly can extend into the device to clean the hidden parts of the dehumidification screen, and the cleaning efficiency is high.
[0030] Specifically, such as Figures 1 to 3 As shown, this cleaning device is used to clean the desiccant screen on a cylindrical device, i.e., the desiccant screen is also cylindrical. The cleaning device includes two first brush assemblies 100 and two second brush assemblies 200. The two first brush assemblies 100 are spaced apart along the axial direction of the desiccant screen and extend circumferentially along its outer periphery. Each first brush assembly 100 includes a first brush handle 110, inner bristles 120, and outer bristles 130. The inner bristles 120 and outer bristles 130 are located on the side of the first brush handle 110 facing the desiccant screen and are spaced apart along the axial direction of the desiccant screen. The two inner bristles 120 are located between the two outer bristles 130. That is, during cleaning, the circumferential direction of the cleaning device is the circumferential direction of the desiccant screen, and the inner bristles 120 and outer bristles 130 can clean the desiccant screen. The two second brush assemblies 200... All 00 extend along the outer periphery of the dehumidification screen, that is, the second brush assembly 200 and the two first brush assemblies 100 are arranged in parallel. Each second brush assembly 200 includes a second brush handle 210 and a middle brush bristle 220. The middle brush bristle 220 is located on the side of the second brush handle 210 facing the dehumidification screen. The two second brush handles 210 are respectively embedded in the two first brush handles 110. The middle brush bristle 220 is located between the corresponding inner brush bristle 120 and outer brush bristle 130. The second brush handle 210 can move relative to the first brush handle 110 along the extension direction of the first brush assembly 100 to extend out of the first brush handle 110 or be stored in the first brush handle 110, so as to adjust the circumference of the cleaning device along the extension direction of the first brush assembly 100.
[0031] Based on the above design, both first brush assemblies 100 and two second brush assemblies 200 extend along the outer periphery of the dehumidification screen and can fit closely to the dehumidification screen, resulting in good cleaning effect and high cleaning efficiency. The first brush assembly 100 includes a first brush handle 110, inner bristles 120 and outer bristles 130, with the inner bristles 120 and outer bristles 130 spaced apart, and the double rows of bristles can improve cleaning efficiency; the second brush assembly 200 includes a second brush handle 210 and a middle bristle 220, with the two second brush handles 210 respectively embedded in the two first brush handles 110, and the middle bristle 220 located between the corresponding inner bristles 120 and outer bristles 130. A portion of the length of the cleaning device has three rows of bristles, namely the inner bristles 120, outer bristles 130 and middle bristles 220, which can further improve cleaning efficiency. The second brush handle 210 can move relative to the first brush handle 110 along the extending direction of the first brush assembly 100, extending out of or retracting into the first brush handle 110. This adjusts the circumference of the cleaning device along the extending direction of the first brush assembly 100, increasing the circumferential coverage of the brush bristles and improving cleaning efficiency. During actual cleaning, the second brush handle 210 is completely retracted into the first brush handle 110, resulting in the shortest circumference of the entire cleaning device. This allows the entire cleaning device to be placed through the narrow opening of the equipment onto the exposed portion of the dehumidifying screen. If necessary, the second brush handle 210 can extend out of the first brush handle 110, increasing the overall circumference of the cleaning device, allowing the second brush assembly 200 to reach inside the equipment to clean the hidden portions of the dehumidifying screen. After cleaning, the second brush handle 210 is retracted into the first brush handle 110, facilitating the removal of the cleaning device from the narrow opening and making storage easier.
[0032] It should be noted that the first brush handle 110 can be integrally formed, with the inner bristles 120 and the outer bristles 130 respectively installed on the first brush handle 110; the first brush handle 110 can also be divided into an inner brush handle and an outer brush handle for separate forming, with the inner brush handle and the outer brush handle connected by hexagonal socket head cap screws and positioning pins, and then the inner bristles 120 and the outer bristles 130 respectively installed on the inner brush handle and the outer brush handle of the first brush handle 110.
[0033] To achieve the connection and fixation of the two first brush assemblies 100, the cleaning device also includes a connecting rod 610, the two ends of which are respectively connected to the ends of the two first brush handles 110 that are opposite to the protruding ends of the second brush handle 210 in the length direction, thereby improving the structural strength of one end of the two first brush assemblies 100 in the circumferential length direction.
[0034] In addition to the ends of the first brush assembly 100, it is also necessary to strengthen the structural strength of the middle part of the two first brush assemblies 100 in the circumferential length direction. The cleaning device also includes a plurality of first support rods 620, which are spaced apart along the extension direction of the first brush assembly 100. The two ends of each first support rod 620 are respectively connected to the side wall of the corresponding end of the first brush handle 110.
[0035] Similarly, the cleaning device also includes a second support rod 700, the two ends of which are respectively connected to the side walls of the corresponding ends of the second brush handle 210, so as to realize the connection and fixation of the two second brush assemblies 200 and improve the structural strength of the ends of the two second brush assemblies 200; at the same time, it can also act as a handle when pushing and pulling the second brush handle 210.
[0036] In this embodiment, the second support rod 700 is a round rod, which is convenient for the operator to hold.
[0037] The cleaning device also includes two locking components 300, which correspond one-to-one with the first brush assembly 100 and the second brush assembly 200. The locking components 300 are used to lock and fix the first brush handle 110 and the second brush handle 210 after adjustment, so as to prevent the first brush handle 110 and the second brush handle 210 from moving relative to each other when the cleaning device is in use.
[0038] In this embodiment, the locking member 300 includes a locking rod and a knob. The two knobs are located on the outside of the two first brush handles 110 respectively and are connected to one end of the locking rod. The other end of the locking rod passes through and connects the first brush handle 110 and the second brush handle 210.
[0039] Furthermore, the first brush handle 110 is provided with a first sliding groove 111 on the side facing the dehumidification screen. The first sliding groove 111 extends along the extension direction of the first brush assembly 100. After the locking member 300 is released, the second brush handle 210 can slide in the first sliding groove 111. The first sliding groove 111 is provided to facilitate the second brush handle 210 to slide out or retract relative to the first brush handle 110, and also to limit the second brush handle 210.
[0040] Optionally, one of the inner sidewall of the first slide groove 111 and the outer sidewall of the second brush handle 210 is provided with a guide strip, and the other is provided with a guide groove 211. The guide strip and the guide strip are adapted to each other and both extend along the length direction of the first slide groove 111 to guide the sliding of the second brush handle 210 in the first slide groove 111 to avoid excessive friction and jamming.
[0041] In this embodiment, the inner wall of the first slide groove 111 is provided with a guide strip, and the outer wall of the second brush handle 210 is provided with a guide groove 211.
[0042] Of course, in other embodiments, the inner sidewall of the first groove 111 and the outer sidewall of the second brush handle 210 may both be provided with grooves, and the two sides of the guide strip may be respectively engaged in the grooves on both sides.
[0043] Optionally, the cleaning device also includes an elastic element 400, with its two ends connected to one end of the first brush handle 110 and the second brush handle 210, respectively. When the locking element 300 is released, the elastic element 400, in a stretched state, can pull the extended second brush handle 210 back into the first slide groove 111, and use the restoring force of the elastic element 400 to achieve automatic storage of the second brush handle 210.
[0044] During the cleaning operation, the locking member 300 is released, and the second brush handle 210 is pulled out of the first slide groove 111 to a suitable length in the direction away from the elastic member 400. The locking member 300 is then locked. Due to the extension, the elastic member 400 generates an elastic restoring force. After cleaning is completed, the locking member 300 is released again, and the second brush handle 210 is pulled back by the elastic member 400 under the restoring force of the elastic member 400 and completely stored in the first slide groove 111.
[0045] In this embodiment, the elastic element 400 is a spring.
[0046] Optionally, the first brush handle 110 has a strip-shaped hole 113 on the side opposite to the first slide groove 111, and the strip-shaped hole 113 extends through the first slide groove 111. The cleaning device also includes a pusher 500, with its two ends respectively passing through the corresponding strip-shaped holes 113 and connected to the second brush handle 210. The pusher 500 can slide within the strip-shaped hole 113 along the extending direction of the first brush assembly 100. The pusher 500 serves as a handle, which facilitates simultaneously pulling or pushing the second brush handle 210 to extend or retract into the first slide groove 111, and also facilitates moving the entire cleaning device along the axial direction of the dehumidification screen during cleaning operations.
[0047] Furthermore, the pusher 500 includes a push rod 510 and two columns 520. The two ends of the push rod 510 are respectively connected to one end of the two columns 520, and one end of the column 520 is connected to the corresponding second brush handle 210.
[0048] Specifically, the two ends of the push rod 510 are connected to two columns 520 by internal hex bolts, and the columns 520 are connected to the second brush handle 210 through threaded holes.
[0049] In this embodiment, the first brush handle 110 is provided with a second groove 112 on the side away from the dehumidification screen. The second groove 112 extends along the extension direction of the first brush assembly 100, and the strip hole 113 is located at the bottom of the second groove 112.
[0050] Furthermore, a fixing post is provided at the end edge of the strip hole 113, one end of the spring is connected to the fixing post, and the other end is connected to the column 520.
[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
