Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing tanks, and in particular to a mixing tank with a self-cleaning function. Background Technology
[0002] In powder coating processing, various materials need to be mixed and stirred, usually using a mixing tank. When using the mixing tank, various materials are added to the tank in proportion through the feed inlet at the top cover. After the materials are added, the motor is started to rotate the stirring frame, which stirs and mixes the materials. After mixing, the mixture is discharged and collected.
[0003] Existing mixing tanks rely solely on the mixing rack for mixing, resulting in mediocre mixing effects. Furthermore, after mixing, it is impossible to scrape the inner wall and bottom of the tank, leading to a large amount of residue. Additionally, the tanks cannot self-clean after mixing, requiring manual cleaning, which can result in incomplete cleaning. Manual cleaning is also inefficient and time-consuming.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0018] like Figures 1-4 As shown, a mixing tank with a self-cleaning function includes a mixing tank body 1, a top cover 2 at the upper end of the mixing tank body 1, a support frame 3 on the top cover 2, a drive motor 4 fixed at the upper end of the support frame 3, a rotating shaft 5 connected to the drive motor 4 inside the mixing tank body 1, a mixing and scraping structure 6 on the rotating shaft 5, and a spraying structure 7 on the top cover 2.
[0019] The lower end of the mixing tank body 1 is provided with a discharge pipe 9, and a connecting frame 10 is installed on the outer wall of the mixing tank body 1. The top cover 2 is provided with a feed pipe 8. The upper end of the rotating shaft 5 passes through the top cover 2, and the upper end of the rotating shaft 5 is connected to the output shaft of the drive motor 4 through a coupling.
[0020] When processing powder coatings, a mixing tank is needed to mix the raw materials. The mixing tank is used for processing. Support legs are provided at the connecting frame 10 on the outer wall of the mixing tank body 1 to support the mixing tank. The spray structure 7 is connected to an external water source. Various raw materials are added into the mixing tank body 1 through the feed pipe 8 on the top cover 2. Then, the drive motor 4 on the support frame 3 is started. The drive motor 4 drives the rotating shaft 5 to rotate. The mixing and scraping structure 6 rotates together to mix the various raw materials. After mixing, the material is discharged through the discharge pipe 9. During discharge, the drive motor 4 rotates in the opposite direction, causing the rotating shaft 5 to rotate in the opposite direction. The mixing and scraping structure 6 rotates in the opposite direction to scrape the material. This can avoid the mixture remaining on the inner wall and bottom of the mixing tank body 1 and prevent waste. After discharge, a self-cleaning process is performed.
[0021] During the self-cleaning process, water from an external water source is sprayed out from the spray structure 7 by a delivery pump. The sprayed water acts on the mixing and scraping structure 6 and the inner wall of the mixing tank body 1. At the same time, the drive motor 4 continues to work, and the rotating shaft 5 rotates the mixing and scraping structure 6. The rotation collides with the cleaning water to clean the mixing and scraping structure 6. Meanwhile, the rotating mixing and scraping structure 6 scrapes and washes the inner wall and bottom of the mixing tank body 1, thus cleaning the inside of the mixing tank body 1. The wastewater from the self-cleaning process is discharged from the discharge pipe 9.
[0022] According to the above implementation scheme, the mixing and scraping structure 6 includes a mixing blade 601, a top connecting rod 602, a bottom scraping rod 603, a spiral scraper 604, and a shaped scraper 605. The mixing blade 601 is fixedly installed on the rotating shaft 5. The top connecting rod 602 is set on the rotating shaft 5 and is located above the mixing blade 601. The bottom scraping rod 603 is fixed to the lower end of the shaped scraper 605 and is located below the mixing blade 601. The bottom scraping rod 603 contacts the inner bottom surface of the mixing tank body 1. The two ends of the spiral scraper 604 are respectively connected to the top connecting rod 602 and the bottom scraping rod 603. The shaped scraper 605 is connected to the bottom scraping rod 603 and contacts the inner wall of the mixing tank body 1.
[0023] The spray structure 7 includes a first spray pipe 701, a second spray pipe 702, a connecting pipe 703, a connecting flange 704, and a nozzle 705. The two connecting pipes 703 are respectively fixed on the first spray pipe 701 and the second spray pipe 702, and the connecting pipes 703 pass through the top cover 2 for fixed installation. The four connecting flanges 704 are respectively set at the ends of the first spray pipe 701 and the second spray pipe 702, and the connecting flanges 704 at the ends of the first spray pipe 701 and the second spray pipe 702 are fixedly connected by bolts and nuts. The nozzles 705 are distributed in a ring array on the first spray pipe 701 and the second spray pipe 702.
[0024] During the mixing of materials, the stirring blades 601 rotate with the rotating shaft 5, playing the main role in mixing. The spiral scraper 604, connected by the top connecting rod 602 and the bottom scraper rod 603, rotates to assist in mixing. After the mixing is completed, the mixture is discharged and then self-cleaning is performed. During the self-cleaning process, water from the water source is transported through the connecting pipe 703 to the first spray pipe 701 and the second spray pipe 702, and finally sprayed from the nozzle 705 onto the mixing and scraping structure 6 and the inner wall of the mixing tank body 1. During the spraying process, the entire mixing and scraping structure 6 rotates, the bottom scraper rod 603 scrapes and cleans the bottom surface of the mixing tank body 1, and the spiral scraper 604, in conjunction with the irregular scraper 605, scrapes and washes the inner wall of the mixing tank body 1 to achieve the purpose of self-cleaning. After the self-cleaning is completed, the wastewater is discharged, and then the drive motor 4 is stopped so that the rotating shaft 5 and the mixing and scraping structure 6 remain stationary.
[0025] It should be noted that the mixing and scraping structure 6, with the mixing blades 601 and the spiral scraper 604, can increase the mixing effect and complete the mixing work in a shorter time. At the same time, during discharge, the bottom scraper 603 and the spiral scraper 604 scrape the bottom and side walls of the mixing tank body 1, avoiding a large amount of residue and reducing waste. A spray structure 7 is set on the top cover 2 and connected to an external water source. After the mixture is discharged, the spray structure 7 sprays water onto the mixing and scraping structure 6 and the inner wall of the mixing tank body 1, which can achieve a rapid self-cleaning effect. When used in conjunction with the spiral scraper 604 and the bottom scraper 603, it can increase the convenience of cleaning and shorten the cleaning time.
