Description

Technical Field

[0001] This utility model relates to the field of glutinous rice flour processing technology, specifically a dust collection device for glutinous rice flour processing. Background Technology

[0002] In the grain processing and flour milling industry, powder needs to be dried. When drying glutinous rice flour, hot air inside the machine circulates repeatedly under the action of a fan, carrying away the moisture discharged from the material through pipes, thereby achieving the purpose of drying. However, some dust is usually carried away by the airflow and dispersed into the air, causing dust pollution on the one hand and raw material loss and waste on the other.

[0003] According to the authorized patent "CN218188499U", a dust collection device for glutinous rice flour processing includes a housing, a filter bag for filtering dust from drying gas, and a cleaning component for cleaning dust adhering to the filter bag. The filter bag is vertically arranged inside the housing, and both ends of the filter bag are horizontally connected to support rings, with the outer end faces of the support rings fixed to the inner wall of the housing. The cleaning component is rotatably arranged inside the housing and vertically fitted onto the outside of the filter bag. This invention overcomes the problem of existing methods that remove glutinous rice flour adhering to the filter bag surface by blowing gas into the filter bag. In this method, the airflow forms a vortex during cleaning, carrying away the powder, causing the blown-off powder to re-adhere to the filter bag surface, thus affecting the cleaning effect of the filter bag.

[0004] The above-mentioned technical solution cleans the dust on the inner wall of the equipment by constantly tapping it during use. Although it can quickly remove the dust, it is easy to damage the inner wall of the main body of the equipment and also generate noise.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 A dust collection device for glutinous rice flour processing includes a drying box 1, a feeding plate 2 snapped onto the top of the drying box 1, a discharge plate 3 provided on the outer side of the bottom of the drying box 1, a controller 4 fixedly connected to the outer side of the drying box 1, and a collection mechanism 5 provided inside the drying box 1.

[0027] The collection mechanism 5 includes a pump 51, a collection box 52 fixedly connected to the outside of the pump 51, an electric telescopic rod 53 fixedly connected to the top of the drying box 1, a lifting rod 54 fixedly connected to the bottom of the electric telescopic rod 53, a motor 55 fixedly connected to the bottom of the lifting rod 54, a rotating shaft 56 fixedly connected to the output end of the motor 55, a movable tube 57 fixedly connected to the bottom outside of the rotating shaft 56, a moving rod 58 movably engaged inside the movable tube 57, a cleaning cover 59 fixedly connected to the outside of the moving rod 58, and a compression spring 510 fixedly connected to the moving rod 58.

[0028] Furthermore: the extraction pump 51 is fixedly connected to the outside of the drying chamber 1, the collection box 52 is fixedly connected to the outside of the drying chamber 1 via the extraction pump 51, the lifting rod 54 is movably connected to the inside of the drying chamber 1, the motor 55 is movably connected to the inside of the drying chamber 1, the electric telescopic rod 53, the extraction pump 51 and the motor 55 are electrically connected to the controller 4, and the motor 55 is made of high temperature resistant material, the movable tube 57 is evenly distributed on the bottom outside of the rotating shaft 56, and the cleaning cover 59 is slidably connected to the inner wall of the drying chamber 1 via the moving rod 58 and the compression spring 510.

[0029] It should be noted that when dust needs to be collected during the glutinous rice flour processing, the operator starts the entire device via controller 4. Controller 4, as the control core of the device, establishes an electrical connection with the electric telescopic rod 53, the extraction pump 51, and the motor 55, enabling precise control of each component and ensuring that the device operates in an orderly manner according to the predetermined program.

[0030] Specifically: The drying chamber 1 is the main structure, with a feeding plate 2 at the top and a discharging plate 3 at the bottom. The drying chamber 1 completes the drying of glutinous rice flour and dust collection. The internal temperature of the drying chamber 1 is relatively high. The motor 55 is made of high-temperature resistant material to ensure long-term stable operation and avoid motor 55 failure due to high temperature. The combination of the moving rod 58 and the compression spring 510 gives the cleaning cover 59 self-adaptive ability, which can fit the inner wall of the drying chamber 1 of different shapes, such as cylindrical and conical, to improve cleaning efficiency.

[0031] As a further improvement of this utility model, the collection box 52 is provided with a cleaning mechanism 6 inside. The cleaning mechanism 6 includes a moving groove 61. A connecting block 62 is fixedly connected to the outside of the moving groove 61. A snap-fit ​​hole 63 is opened inside the connecting block 62. A connecting plate 64 is fixedly connected to the outside of the collection box 52. A positioning rod 65 is movably connected inside the connecting plate 64. A limit cover 66 is fixedly connected to the top of the positioning rod 65.

[0032] Furthermore: the movable slot 61 is movably connected to the inside of the collection box 52, and one end of the movable slot 61 is located on the outside of the collection box 52, the connecting block 62 is located on the outside of the collection box 52, and the bottom of the positioning rod 65 is located inside the snap-fit ​​hole 63.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] Working principle: When it is necessary to collect dust inside the drying chamber 1, the extraction pump 51 is fixedly connected to the outside of the drying chamber 1 and starts working upon the start command of the controller 4. The extraction pump 51 generates suction, drawing the dust generated inside the drying chamber 1 during the glutinous rice flour processing into the collection box 52 through pipes and other connecting structures. The collection box 52 is fixedly connected to the outside of the drying chamber 1 via the extraction pump 51, providing a collection and storage space for the dust.

[0035] The electric telescopic rod 53 is fixed to the top of the drying chamber 1 and is activated under the control of the controller 4. The telescopic movement of the electric telescopic rod 53 drives the lifting rod 54, which is fixedly connected to the bottom, to move up and down inside the drying chamber 1. The motor 55 connected to the bottom of the lifting rod 54 also adjusts its height accordingly to adapt to different cleaning needs and working scenarios.

[0036] Motor 55 starts under the control of controller 4, and the rotating shaft 56 fixedly connected to its output end begins to rotate. Movable tubes 57, evenly distributed on the outer side of the bottom of the rotating shaft 56, rotate synchronously with the shaft. The movable rod 58, movably engaged inside the movable tube 57, moves along the inside of the movable tube 57 under the action of centrifugal force and the inner wall of the drying chamber 1, simultaneously driving the cleaning cover 59, fixedly connected to the outside, to move in a circular motion against the inner wall of the drying chamber 1, cleaning the dust adhering to the inner wall of the drying chamber 1. The compression spring 510 fixedly connected to the movable rod 58 acts as a buffer and reset mechanism, ensuring that the cleaning cover 59 maintains appropriate contact pressure with the inner wall of the drying chamber 1, ensuring cleaning effectiveness while preventing excessive friction and damage to the equipment. Simultaneously, the cleaned dust is then pumped into the collection box 52 by the extraction pump 51, achieving efficient collection.

[0037] When the dust collected inside the collection box 52 reaches a certain amount and cleaning is required, the operator operates the controller 4 to stop the operation of the pump 51 and related components. Then, the operator holds the limit cover 66 and pulls the positioning rod 65 upward, causing the bottom of the positioning rod 65 to disengage from the snap-fit ​​hole 63 inside the connecting block 62. At this time, the positioning constraint between the moving groove 61 and the collection box 52 is released.

[0038] The movable slot 61 is movably connected to the inside of the collection box 52, with one end located on the outside of the collection box 52. After the positioning rod 65 disengages from the snap-fit ​​hole 63, the operator can follow the guide of the movable slot 61 to pull the movable slot 61 and the cleaning component connected to it out of the collection box 52, making it convenient to clean the dust adhering to the inside of the collection box 52 and the cleaning component;

[0039] After cleaning, align the movable slot 61 with the installation position of the collection box 52, and push it into the collection box 52 along the guide of the movable slot 61. Then, align the positioning rod 65 with the snap-fit ​​hole 63, and push the limiting cover 66 downward so that the bottom of the positioning rod 65 is reinserted into the snap-fit ​​hole 63, thereby repositioning and fixing the movable slot 61 and the collection box 52, preparing for the next dust collection and cleaning operation.
