Description

Technical Field

[0001] This utility model belongs to the technical field of tea processing equipment, specifically relating to a dust removal device for tea production workshops. Background Technology

[0002] Tea leaves refer to the leaves and buds of the tea plant, typically used for brewing tea. After the leaves undergo withering, fermentation, fixation, rolling, and drying, the resulting tea is called primary processed tea. During tea processing, the fine hairs on the surface of the tea leaves fall off and disperse; if these hairs get mixed in, they will lower the quality of the tea. At the same time, a large amount of dust is generated in the processing workshop, so dust removal equipment is needed during processing.

[0003] A dust removal system for a tea production workshop, as shown in announcement number CN219292343U, includes a mounting plate and a dust collection chamber fixed to the upper surface of the mounting plate. Pneumatic push rods are mounted on both sides of the mounting plate, and a suction hood is fixed to the lower telescopic end of each pneumatic push rod. A spring tube is installed between the suction hood and the dust collection chamber, and a protective cover is fixed to the upper end of the spring tube. A liquid pump is fixed to the bottom of the inner cavity of the dust collection chamber, and a horizontal pipe is horizontally fixed to the upper end of the inner cavity of the dust collection chamber. In this device, although the secondary filtration through spraying and the filter cartridge can effectively filter dust from the gas and prevent air pollution, and the drive motor can drive a cleaning brush to scrape the surface of the filter cartridge to clean the accumulated dust, effectively preventing dust from clogging the filter cartridge, during use, the water vapor generated by the spraying combines with dust and adheres to the outer wall of the filter cartridge. Long-term use can lead to filter cartridge clogging, thus affecting the filtration effect. Utility Model Content

[0004] The purpose of this utility model is to provide a dust removal device for tea production workshops, so as to solve the problem in the prior art that the use of filter cartridges causes water vapor and dust to combine and adhere to the outer wall of the filter cartridge, thereby affecting the filtration effect.

[0021] 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.

[0022] Referring to Figures *-*, this utility model provides a dust removal device for a tea production workshop, including a dust removal chamber 1. A negative pressure device 2 is installed at the upper end of the dust removal chamber 1, and a telescopic rod 3 is fixedly connected to the lower end of the dust removal chamber 1. An air suction hood 4 is fixedly connected to the output shaft end of the telescopic rod 3. The upper end of the air suction hood 4 is fixedly connected to the rear end of the dust removal chamber 1 through a corrugated pipe 5. A filter mechanism 6 is installed inside the dust removal chamber 1. The filter mechanism 6 is used to filter the gas. During operation, the filter belt 62 and guide roller 61 in the filter mechanism 6 realize the functions of continuous filtration and cleaning. The filter belt 62 circulates under the drive of the guide roller 61, which can continuously filter the dust in the gas and avoid the problem of clogging of traditional filter cartridges due to long-term use.

[0023] In a further embodiment, refer to Figure 2 The filtration mechanism 6 includes guide rollers 61 and filter belts 62. Guide rollers 61 are rotatably connected inside the dust collection chamber 1. Four sets of guide rollers 61 are evenly distributed at the four corners of the dust collection chamber 1. Cleaning rollers 63 are rotatably connected inside the dust collection chamber 1. Two sets of cleaning rollers 63 are located on the upper and lower sides of the filter belt 62 at the lower end of the dust collection chamber 1. Spray pipes 64 are fixedly connected to the left end of the dust collection chamber 1. Spray pipes 64 are located on the left and right sides of the filter belt 62 on the left side of the dust collection chamber 1. Squeeze rollers 65 are rotatably connected inside the dust collection chamber 1. Two sets of squeeze rollers 65 are located on the left and right sides of the filter belt 62 on the left side of the dust collection chamber 1. A drain pipe 11 is fixedly connected to the lower end of the dust collection chamber 1.

[0024] In this embodiment, the filter belt 62 circulates under the drive of the guide roller 61, continuously filtering dust in the gas. Cleaning water is injected into the dust removal chamber 1, so that when the filter belt 62 is fed into the cleaning roller 63, the rotation of the cleaning roller 63 can clean the filter belt 62. Then, the filter belt 62 is fed into the spray pipe 64. At this time, the water sprayed through the spray pipe 64 will further remove the adhering substances on the surface of the filter belt 62. Finally, the water in the sprayed and cleaned filter belt 62 is squeezed out to ensure that the filter belt 62 remains dry and avoids affecting the filtration effect due to residual water. When the cleaned filter belt 62 is then put into the filtered gas, the filter belt 62 can be recycled.

[0025] In a further embodiment, refer to Figures 1-3 A motor 66 is fixedly connected to the front end of the dust collection chamber 1. The output shaft of the motor 66 is fixedly connected to the front end of the cleaning roller 63. The rear ends of the two sets of cleaning rollers 63 are fixedly connected to the second gear 631, which mesh with each other. The rear ends of the guide rollers 61 adjacent to the cleaning rollers 63 are fixedly connected to the first gear 611, which meshes with the second gear 631. The front ends of the guide rollers 61 adjacent to the cleaning rollers 63 are connected to the front ends of the extrusion rollers 65 through a second synchronous belt assembly 8. The rear ends of the two sets of extrusion rollers 65 are fixedly connected to the third gear 651, which meshes with each other. The front ends of the extrusion rollers 65 are connected to the front ends of the guide rollers 61 on the upper left side of the dust collection chamber 1 through a first synchronous belt assembly 7.

[0026] In this embodiment, since the first gear 611 and the second gear 631 mesh with each other, after the motor 66 starts, it can simultaneously drive the cleaning roller 63 and the guide roller 61 to rotate. The squeeze roller 65 is rotatably connected to the upper and lower sets of guide rollers 61 on the left side of the dust removal chamber 1 through the first synchronous belt assembly 7 and the second synchronous belt assembly 8, respectively. Thus, the rotation of the guide roller 61 on the left side of the dust removal chamber 1 can simultaneously drive the squeeze roller 65 to rotate. Therefore, the start of the motor 66 can simultaneously provide power for the rotation of the cleaning roller 63, the squeeze roller 65 and the guide roller 61.

[0027] In a further embodiment, refer to Figure 4 The upper part of the dust removal chamber 1 is fixedly connected to a limiting plate 9. The limiting plate 9 is provided in two sets and is located on the front and rear sides of the filter belt 62. The limiting plate 9 is set in an "L" shape and is symmetrical to each other.

[0028] In this embodiment, the limiting plate 9 is L-shaped, with its vertical part closely attached to the edge of the filter belt 62 and its horizontal part located below the filter belt 62; this not only effectively limits the offset of the filter belt 62, but also provides a certain support effect for the filter belt 62.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
