Description

Technical Field

[0001] This utility model relates to the field of calcium carbonate production technology, specifically to an overload protection device for calcium carbonate stirring equipment. Background Technology

[0002] Heavy calcium carbonate, or calcium carbonate for short, is made from ground natural carbonate minerals such as calcite, marble, and limestone. It is a commonly used powdered inorganic filler with advantages such as high chemical purity, high inertness, low chemical reactivity, good thermal stability (it will not decompose below 400℃), high whiteness, low oil absorption, low refractive index, softness, dryness, absence of crystallization water, low hardness, low abrasion value, non-toxicity, tastelessness, odorlessness, and good dispersibility. It is commonly used as a filler in various industries including artificial floor tiles, rubber, plastics, papermaking, coatings, paints, inks, cables, building materials, food, pharmaceuticals, textiles, feed, toothpaste, and other daily chemical products. As a filler, it increases product volume and reduces production costs.

[0003] Patent document CN218222224U discloses a stirring device for producing heavy calcium carbonate, belonging to the field of calcium carbonate production technology. The mounting base is a hollow cylinder with an opening at one end away from the ground. A housing is embedded inside the mounting base, and a drive motor is fixedly connected to the bottom of the mounting base. The output end of the drive motor is connected to an output shaft, which is embedded in the bottom of the housing. Several scrapers are fixedly connected to the bottom of the stirring chamber and to the outer wall around the output shaft. Stirring blades are fixedly connected to the top of the scrapers and to the outer wall around the output shaft. Several crushing blades are installed on the inner wall of the stirring chamber, evenly distributed from top to bottom. This stirring device for producing heavy calcium carbonate can break up clumps of heavy calcium carbonate through the stirring blades and crushing blades, and the scrapers can remove heavy calcium carbonate adhering to the bottom, effectively improving the production quality and output efficiency of heavy calcium carbonate.

[0004] Although the aforementioned application documents state that the agitator blades and crusher blades can break up the clumps of heavy calcium carbonate and the scraper can remove the heavy calcium carbonate stuck to the bottom, effectively improving the production quality and output efficiency of heavy calcium carbonate, the vortex causes unidirectional inertial motion during use, resulting in insufficient mixing of materials in some areas and over-mixing in others.

[0005] Therefore, an overload protection device for calcium carbonate stirring equipment is proposed to solve the problems mentioned above. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an overload protection device for calcium carbonate stirring equipment, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: including a mixing tank, wherein a mixing device is installed inside the mixing tank;

[0008] The stirring device includes a rotating rod, which is rotatably connected to the top of the inner wall of the stirring tank via a bearing. A connecting rod is fitted to the bottom of the rotating rod, and a first inclined plate is fixedly connected to the outer wall of the connecting rod. A fixed plate is fixedly connected to the bottom of the inner wall of the stirring tank, and a second inclined plate is fixedly connected to the back of the fixed plate. A fixed seat is fixedly connected to the top of the stirring tank, and a motor is fixedly connected to the front of the fixed seat. The rotating rod moves through the stirring tank, and its extension end extends towards the top of the stirring tank. The extension end of the rotating rod is fixedly connected to the output end of the motor. A spring-loaded safety coupling is fitted to the extension end of the rotating rod and the output end of the motor. A reciprocating assembly that drives the first inclined plate to move back and forth is installed inside the stirring tank.

[0009] Preferably, the reciprocating assembly includes a chute cylinder, which is fixedly connected to the top of the inner wall of the mixing tank. A connecting sleeve is slidably connected to the outer wall of the rotating rod, and a pulley is hinged to the outer wall of the connecting sleeve. The pulley is slidably connected to the inner wall of the chute cylinder, and a fixing cylinder is fixedly connected to the outer wall of the chute cylinder.

[0010] Preferably, the first inclined plate is lower on the left and higher on the right, the second inclined plate is higher on the left and lower on the right, and the connecting rod is fixedly connected to the bottom of the connecting sleeve.

[0011] Preferably, there are four first inclined plates and four second inclined plates.

[0012] Preferably, the mixing tank is equipped with a scraping device for scraping the inner wall of the mixing tank.

[0013] Preferably, the scraping device includes a fixing block, which is fixedly connected to the bottom of the connecting rod. A turntable is rotatably connected to the bottom of the fixing block via a bearing. A hydraulic chamber is fixedly connected to the bottom of the inner wall of the mixing tank. A first hydraulic rod is slidably connected to a piston at one end of the hydraulic chamber. The first hydraulic rod is fixedly connected to the bottom of the turntable.

[0014] Preferably, a second hydraulic rod is slidably connected to a piston at one end inside the hydraulic chamber, and five scraping rings are fixedly connected to the outer wall of the second hydraulic rod.

[0015] Compared with the prior art, this utility model provides an overload protection device for calcium carbonate stirring equipment, which has the following beneficial effects:

[0016] First, the spiral ascent and descent are generated by components such as the connecting sleeve, connecting rod, and first inclined plate. The interaction between the first and second inclined plates disperses the linear momentum of the fluid and prevents vortices from generating unidirectional inertial motion. This solves the problem of insufficient mixing of materials in some areas and over-mixing in others, thereby achieving a more uniform material mixing effect.

[0017] 2. When the connecting rod descends, a series of mechanical linkages (fixed block, turntable, first hydraulic rod, second hydraulic rod) ultimately drive the scraping ring to rise. During the rising process, the scraping ring can scrape off the fluid adhering to the inner wall of the mixing tank, preventing the fluid from accumulating on the inner wall of the mixing tank, thereby improving mixing efficiency and cleaning effect.

[0023] 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.

[0024] Example 1

[0025] See Figures 1-4This embodiment provides an overload protection device for a calcium carbonate stirring equipment, including a stirring tank 1, and a stirring device 2 is installed inside the stirring tank 1.

[0026] The stirring device 2 includes a rotating rod 21, which is rotatably connected to the top of the inner wall of the stirring tank 1 via a bearing. A connecting rod 29 is mounted at the bottom of the rotating rod 21, and a first inclined plate 210 is fixedly connected to the outer wall of the connecting rod 29. A fixed plate 211 is fixedly connected to the bottom of the inner wall of the stirring tank 1, and a second inclined plate 24 is fixedly connected to the back of the fixed plate 211. A fixed seat 23 is fixedly connected to the top of the stirring tank 1, and a motor 22 is fixedly connected to the front of the fixed seat 23. The rotating rod 21 moves through the stirring tank 1, and the extended end of the rotating rod 21 extends toward the top of the stirring tank 1. The extended end of the rotating rod 21 is fixedly connected to the output end of the motor 22. A spring-loaded safety coupling 4 is mounted on the extended end of the rotating rod 21 and the output end of the motor 22. A reciprocating assembly that drives the first inclined plate 210 to move back and forth is installed inside the stirring tank 1.

[0027] The reciprocating assembly includes a chute 25, which is fixedly connected to the top of the inner wall of the mixing tank 1. A connecting sleeve 26 is slidably connected to the outer wall of the rotating rod 21. A pulley 27 is hinged to the outer wall of the connecting sleeve 26. The pulley 27 is slidably connected to the inner wall of the chute 25. A fixed cylinder 28 is fixedly connected to the outer wall of the chute 25.

[0028] The first inclined plate 210 is lower on the left and higher on the right, the second inclined plate 24 is higher on the left and lower on the right, and the connecting rod 29 is fixedly connected to the bottom of the connecting sleeve 26.

[0029] There are four first inclined plates 210 and four second inclined plates 24.

[0030] In practical use, the above-mentioned equipment is activated by starting the motor 22, which drives the rotating rod 21 to rotate. The rotating rod 21 drives the connecting sleeve 26 to rotate. The connecting sleeve 26 is slidably connected to the bottom of the inner wall of the chute cylinder 25 via the pulley 27 on the outer wall. The chute cylinder 25 causes the connecting sleeve 26 to reciprocate up and down. The rotating rod 21 drives the connecting sleeve 26 to rotate, which in turn drives the connecting rod 29 to rotate. The connecting rod 29 drives the first inclined plate 210 to rotate, causing the fluid to collide with the second inclined plate 24, thereby reducing the unidirectional inertial motion generated by the vortex. The reciprocating up and down motion of the connecting sleeve 26 is superimposed on the rotational motion of the rotating rod 21, causing the first inclined plate 210 to rotate. The motion trajectory becomes a spiral ascent and descent. At the same time, with the first inclined plate 210 in a left-low-right-high configuration, it tends to push the fluid to the upper right when rotating. However, with the second inclined plate 24 in a left-high-right-low configuration, it tends to deflect the fluid to the lower left, generating a reverse tangential flow. When the first inclined plate 210 drives the fluid to collide with the second inclined plate 24, the two inclined surfaces in opposite directions collide and exchange momentum, dispersing the linear momentum of the fluid and preventing the accumulation of unidirectional flow. The power transmission is automatically cut off when the torque at the output end of the motor 22 exceeds the preset value through the spring-loaded safety coupling 4, model ROBA-DS40.

[0031] Example 2

[0032] See Figures 1-4 Based on Embodiment 1, the mixing tank 1 is equipped with a scraping device 3 for scraping the inner wall of the mixing tank 1.

[0033] The scraping device 3 includes a fixing block 31, which is fixedly connected to the bottom of the connecting rod 29. The bottom of the fixing block 31 is rotatably connected to a turntable 33 via a bearing. A hydraulic chamber 32 is fixedly connected to the bottom of the inner wall of the mixing tank 1. A first hydraulic rod 34 is slidably connected to one end of the hydraulic chamber 32 by a piston. The first hydraulic rod 34 is fixedly connected to the bottom of the turntable 33.

[0034] Inside the hydraulic chamber 32, a second hydraulic rod 35 is slidably connected to a piston at one end, and five scraping rings 36 are fixedly connected to the outer wall of the second hydraulic rod 35.

[0035] When the above-mentioned equipment is used, when the connecting rod 29 descends, it drives the fixed block 31 to descend, the fixed block 31 drives the turntable 33 to descend, the turntable 33 drives the first hydraulic rod 34 to descend, during the process of the first hydraulic rod 34 descending, the internal pressure of the hydraulic chamber 32 increases, which drives the second hydraulic rod 35 to rise, and the rise of the second hydraulic rod 35 drives the scraping ring 36 to rise, scraping off the fluid adhering to the inner wall of the mixing tank 1.

[0036] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0037] 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.
