Description

Technical Field

[0001] This utility model relates to the field of mixing tank technology, and in particular to a splash-proof and dust-proof mixing tank. Background Technology

[0002] Mixed tanks are crucial equipment in the silicon rod processing industry for material mixing, reaction, and homogenization. During mixing, especially when the material is a liquid, slurry, or powder that easily generates dust, splashing or dust emission often occurs. This not only causes material loss and environmental pollution but also poses threats to equipment safety and the health of operators. Therefore, effectively achieving sealing, splash prevention, and dust control during the mixing process has always been a key focus for those skilled in the art.

[0003] In existing technologies, a common solution to address the aforementioned problems is to install a fixed cover at the opening of the mixing tank and seal the agitator shaft through a bearing at the center of the cover. While this structure can limit splashing and dust to some extent, it still has significant drawbacks. First, the dynamic sealing structure between the agitator shaft and the cover is complex and prone to failure due to wear after long-term use, resulting in inadequate sealing and high maintenance and replacement costs. Second, and more critically, this fixed cover hinders the overall lifting and lowering of the agitator assembly, making operation extremely inconvenient when cleaning residual materials from the tank's inner wall or performing maintenance. Workers often need to manually open the fixed cover for cleaning, which is not only inefficient but also fails to achieve automated cleaning. Furthermore, traditional mixing tanks typically focus on the agitation function itself, and their agitator rods often cannot effectively scrape off materials adhering to the tank's inner wall, easily leading to material accumulation, uneven mixing, and even cross-contamination. Therefore, there is an urgent need in the field for a mixing device that integrates effective sealing and easy-to-maintain automated tank wall cleaning functions to overcome the shortcomings of existing technologies in terms of practicality, maintainability, and cleaning efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a splash-proof and dust-proof mixing tank that can overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, a splash-proof and dust-proof mixing tank is provided, including a support base and a mixing tank body. A sliding frame is fixedly connected to the upper side wall of the support base, and a sliding seat is slidably connected inside the sliding frame. A drive motor is installed on the upper side wall of the sliding seat, and a drive wheel is fixedly connected to the output end of the drive motor. A connecting shaft is fixedly connected to the lower side wall of the sliding seat.

[0006] A driven wheel is rotatably connected to the outer side wall of the connecting shaft, a transmission seat is fixedly connected to the lower side wall of the driven wheel, a transmission box is fixedly connected to the lower side wall of the transmission seat, two connecting rods are rotatably connected inside the transmission box, and a stirring rod is fixedly connected to the lower end of each connecting rod. A scraper is fixedly connected to the outer side wall of the transmission box through a connecting frame.

[0007] According to the splash-proof and dust-proof mixing tank, two guide rods are fixedly connected inside the sliding frame, and each guide rod is slidably connected to the sliding seat to improve the stability of the sliding seat.

[0008] According to the splash-proof and dust-proof mixing tank, a hydraulic push rod is installed on the lower inner wall of the sliding frame. The output end of the hydraulic push rod is fixedly connected to the lower side wall of the sliding seat. The hydraulic push rod can drive the sliding seat to move up and down, thereby driving the dust cover and the mixing assembly to move up and down.

[0009] According to the splash-proof and dust-proof mixing tank, a bearing is installed on the outer wall of the transmission seat, and a dust cover is installed on the outer wall of the bearing. The dust cover cooperates with the main body of the mixing tank to effectively prevent splashing and dust.

[0010] According to the splash-proof and dust-proof mixing tank, the driving wheel drives the driven wheel to rotate via a transmission belt.

[0011] According to the splash-proof and dust-proof mixing tank, the connecting shaft and the transmission base are rotatably connected.

[0012] According to the splash-proof and dust-proof mixing tank, a drive gear is fixedly connected to the lower end of the connecting shaft, and a driven gear is fixedly connected to the outer side wall of each connecting rod. Both driven gears mesh with the drive gear. When the driven wheel rotates, the transmission seat rotates relative to the connecting shaft. At this time, the driven wheel rotates relative to the drive gear, thereby driving the mixing rod to rotate through the connecting rod.

[0013] According to the splash-proof and dust-proof mixing tank, the scraper is in contact with the inner wall of the mixing tank body, which facilitates the scraping of materials remaining on the inner wall of the mixing tank body.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model fundamentally solves the problems of easy wear and leakage of traditional shaft seals and inconvenient equipment maintenance by combining a liftable integrated stirring assembly with a static dust cover. A hydraulic push rod drives the sliding seat, which integrates the motor and stirring components, to rise and fall as a whole, allowing the dust cover fixed on it to move accordingly and achieve a reliable static seal with the tank opening, replacing the easily failing dynamic shaft seal. This design allows the stirring assembly to be completely removed from the tank during cleaning and maintenance, providing ample operating space and greatly improving the safety and maintainability of the equipment.

[0016] 2. This invention achieves automated linkage between stirring and scraping functions, effectively solving the problems of uneven mixing and cross-contamination caused by material residue on the tank wall. The scraper is fixed to the outside of the transmission box, which rotates with the transmission box, via a connecting frame, and can simultaneously and continuously scrape off the adhering material on the tank wall during stirring. This self-cleaning function avoids interrupted manual cleaning during production, ensuring not only the mixing quality and full utilization of materials, but also significantly improving production efficiency, making it particularly suitable for working conditions with strict cleanliness requirements.

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-4 This utility model discloses a splash-proof and dust-proof mixing tank, which includes a support base 1 and a mixing tank body 2. A sliding frame 101 is fixedly installed on the upper side of the support base 1. Two parallel guide rods 103 are provided inside the sliding frame 101. The sliding seat 3 is slidably connected to the sliding frame 101 through the guide rods 103 to ensure that the sliding seat 3 remains stable during up and down movement. A hydraulic push rod 102 is installed at the bottom of the sliding frame 101. The output end of the hydraulic push rod 102 is fixedly connected to the lower side of the sliding seat 3 for driving the sliding seat 3 to move up and down along the guide rods 103.

[0026] A drive motor 4 is mounted on the upper side of the sliding seat 3, and the output shaft of the drive motor 4 is fixedly connected to the drive wheel 401. A connecting shaft 302 is fixedly connected to the lower side of the sliding seat 3, and a driven wheel 301 is rotatably connected to the outer side of the connecting shaft 302 via a bearing. The drive wheel 401 is connected to the driven wheel 301 via a transmission belt 402 to realize power transmission.

[0027] A transmission seat 5 is fixedly connected to the lower side of the driven wheel 301, and a transmission box 503 is fixedly connected to the lower side of the transmission seat 5. A dust cover 501 is installed on the outer side of the transmission seat 5 via a bearing. The dust cover 501 fits with the upper opening of the mixing tank body 2 to form a sealing structure, effectively preventing liquid splashing or dust from being emitted during the mixing process.

[0028] The lower end of the connecting shaft 302 extends into the transmission box 503 and is fixedly connected to the drive gear 303. Two connecting rods 701 are rotatably connected inside the transmission box 503. Each connecting rod 701 has a driven gear 502 fixedly connected to its upper end, and both driven gears 502 mesh with the drive gear 303. The lower end of the connecting rod 701 extends to the bottom of the transmission box 503 and is fixedly connected to the stirring rod 7.

[0029] A scraper 6 is fixedly connected to the outside of the transmission box 503 via a connecting frame 601. The shape of the scraper 6 fits the inner wall of the mixing tank body 2, and can scrape off the material adhering to the tank wall during the mixing process.

[0030] Working principle: When the drive motor 4 starts, the driving wheel 401 drives the driven wheel 301 to rotate via the transmission belt 402. The driven wheel 301 drives the transmission seat 5 and the transmission box 503 to rotate as a whole. Since the connecting shaft 302 and the transmission seat 5 are rotatably connected, and the driving gear 303 is fixed at the lower end of the connecting shaft 302, the rotation of the driven wheel 301 causes the transmission seat 5 to rotate relative to the connecting shaft 302. Thus, through the meshing of the driving gear 303 and the driven gear 502, the two connecting rods 701 and the stirring rod 7 below them rotate, thereby achieving the stirring of materials. At the same time, the hydraulic push rod 102 can push the sliding seat 3 to move up and down along the guide rod 103, thereby driving the entire stirring assembly (including the transmission seat 5, dust cover 501, transmission box 503, stirring rod 7 and scraper 6) to rise and fall. During the mixing process, the dust cover 501 always covers the opening of the mixing tank body 2 to prevent splashing and dust; the scraper 6 rotates with the transmission box 503 and continuously scrapes the tank wall to avoid material residue.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
