Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a liftable annular stirring and scraping device. Background Art

[0002] Conductive slurries have good elasticity, are resistant to heat and aging, and have excellent coating adhesion and applicability. They are widely used in fields such as battery vehicles and have high application value. However, during the premixing and stirring process of the conductive slurry production process, the production raw materials often accumulate on the inner wall of the tank outside the stirring range of the stirring paddle. For some slurries with high viscosity, dispersion with a single stirring paddle is even more difficult and the subsequent cleaning is troublesome.

[0003] Existing stirring scraper devices, such as the Chinese patent with authorization announcement number CN214915208U, discloses a stirring scraper device that drives the stirring shaft to rotate by a motor, thereby driving the scraper to move, removing the material adhered to the inner wall of the tank, thereby preventing the production raw materials from condensing on the inner wall of the tank, improving production efficiency, and reducing subsequent cleaning time.

[0004] However, when the above-mentioned stirring and scraping device is stirring and scraping the material, it only scrapes the wall within a certain range and has a small coverage area. This makes the stirring and scraping device insufficient and incomplete in scraping the wall during use, thereby causing inconvenience in cleaning the bottom or excessive viscous slurry clogging the discharge port, causing discontinuous discharge. For this reason, a liftable annular stirring and scraping device is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a liftable annular stirring and scraping device, which effectively solves the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present utility model provides the following technical solutions.

A driving mechanism is provided on the top of the stirring tank body, which is used to drive the sliding rod to perform lifting, sliding and adjustment. A stirring mechanism for stirring is also provided in the stirring tank body.

[0008] It can be seen that the driving mechanism can drive each sliding rod to slide and rise and fall along the guide hole, and then drive the annular scraper to rise and fall synchronously with the inner wall of the mixing tank, so as to scrape off the solidified material attached to the inner wall of the mixing tank, prevent the solidified material from sticking to the inner wall of the mixing tank, ensure the cleanliness of the inner wall of the tank and smooth discharge of the material, and the driving mechanism lifts the scraper, the scraping coverage is large, and the scraping is more sufficient and thorough.

[0009] Furthermore, the driving mechanism includes a pair of vertical frames, a suspension, a threaded rod, a driving motor, a nut seat and a pair of cantilevers. The two vertical frames are symmetrically fixed vertically on the top of the mixing tank body, the suspension is fixed on the top of the two vertical frames, the threaded rod is rotatably installed on the lower surface of the suspension, the driving motor is fixed on the top of the suspension, and the output shaft is fixedly connected to the top of the threaded rod.

Cantilevers are respectively fixed on both sides of the nut seat, and the top of the sliding rod is fixedly connected to the cantilever on the corresponding side.

[0010] Furthermore, the stirring mechanism includes a stirring shaft extending vertically inside the stirring tank body and a number of stirring rods evenly distributed on the outer wall of the stirring shaft. The top end of the stirring shaft extends through the top of the stirring tank body and is fixedly connected to the bottom end of the threaded rod through a connecting head.

[0011] Furthermore, the stirring shaft and the annular scraper are coaxially arranged, and the distance between the end of each stirring rod away from the stirring shaft and the axis of the stirring shaft is smaller than the distance between the inner edge wall of the annular scraper and the axis of the stirring shaft.

[0012] Furthermore, at least two feed ports are provided on the top of the mixing tank body, a water inlet pipe is provided on one side of the mixing tank body, and a water outlet pipe is provided on the other side. The water outlet pipe is arranged higher than the water inlet pipe. Support legs are evenly distributed on the bottom of the mixing tank body, and a discharge device is also provided at the bottom of the mixing tank body.

[0013] Furthermore, the discharge device includes a discharge pump chamber, a discharge pump and a discharge pipe. The discharge pump chamber is fixed at the bottom of the stirring tank body, the discharge pump is installed in the discharge pump chamber, the input part of the discharge pump is communicated with the bottom of the stirring tank body, the discharge pipe is connected to the outer surface of the discharge pump chamber, and extends into the discharge pump chamber and is communicated with the output part of the discharge pump. A discharge valve is installed on the discharge pipe.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0015] The utility model can drive each slide bar to slide and rise and fall along the guide hole through the operation of the driving mechanism, and then can drive the annular scraper to synchronously rise and fall in contact with the inner wall of the mixing tank, so as to scrape off the solidified material attached to the inner wall of the mixing tank, prevent the solidified material from sticking to the inner wall of the mixing tank, ensure the cleanliness of the inner wall of the tank and smooth discharge of the material, and the driving mechanism lifts the scraper, the scraping coverage area is large, and the scraping is more sufficient and thorough.

[0025] See also Figures 1-4 The utility model provides a liftable annular stirring and scraping device, comprising a stirring tank body 1 and an annular scraper 2. At least two vertically penetrating guide holes 11 are provided on the top of the stirring tank body 1. A slide rod 12 is vertically slidably installed in each guide hole 11. The annular scraper 2 is fixed on the end of the slide rod 12 extending into the stirring tank body 1, and the outer edge wall is slidably fitted with the inner wall of the stirring tank body 1. A driving mechanism 3 is provided on the top of the stirring tank body 1, and the driving mechanism 3 is used to drive the slide rod 12 to perform lifting and sliding adjustment. A stirring mechanism 4 for stirring is also provided in the stirring tank body 1.

[0026] The liftable annular stirring and scraping device provided by the utility model can stir the material in the stirring tank body 1 through the operation of the stirring mechanism 4, and can drive each slide rod 12 to slide and lift along the guide hole 11 through the operation of the driving mechanism 3, thereby driving the annular scraper 2 to synchronously lift and lift in contact with the inner wall of the stirring tank body 1, so as to scrape off the solidified material attached to the inner wall of the stirring tank body 1, prevent the solidified material from sticking to the inner wall of the stirring tank body 1, ensure the cleanliness of the inner wall of the tank body and smooth discharge of the material, and the lifting scraping of the driving mechanism 3 has a large scraping coverage area and is more sufficient and thorough.

[0027] Specifically, the driving mechanism 3 includes a pair of upright frames 31, a suspension 32, a threaded rod 33, a driving motor 34, a nut seat 35 and a pair of cantilevers 36. The two upright frames 31 are symmetrically fixed vertically on the top of the mixing tank body 1, the suspension 32 is fixed on the top of the two upright frames 31, the threaded rod 33 is rotatably mounted on the lower surface of the suspension 32, the driving motor 34 is fixed on the top of the suspension 32, and the output shaft is fixedly connected to the top of the threaded rod 33. The nut seat 35 is threadedly matched and sleeved on the threaded rod 33, and the two sides of the nut seat 35 are respectively connected to the two upright frames. The inner surface of 31 slides in fit, ensuring that the nut seat 35 can slide up and down between the two upright frames 31. Cantilevers 36 are fixed on both sides of the nut seat 35.
