Description

A clay mixer for ceramic crafts Technical Field

[0001] This invention relates to the field of ceramic production technology, and in particular to a mud mixer for ceramic handicrafts. Background Technology

[0002] In the ceramic production process, the raw materials need to be mixed into a slurry-like material of water and solids. At the same time, a slurry filtration device is required during processing. The slurry is filtered through a fixed filter plate to reduce impurities in the material and improve product quality. The effect of slurry filtration directly affects the economic benefits of the manufacturer's ceramic products.

[0003] Chinese patent application number 202222692787.5 discloses an iron removal and grading screening device for ceramic production slurry, including a box body. A shell is fixedly connected inside the box body, and a stirring mechanism is fixedly connected inside the shell. The box body is positioned and fixed for use. During operation, it is connected to the feed pipe inside the cover plate mechanism to inject slurry material. Activating the internal stirring mechanism causes the motor to drive the connecting shaft to rotate, rotating the internal long column. Simultaneously, the internal push plate pushes and adheres to the filter screen, uniformly mixing the slurry and facilitating its descent. The material is discharged through the discharge pipe via the internal inclined filter plate. Simultaneously, the filtered material enters the interior of the inclined plate and is discharged through the external conveying pipe, thus completing the slurry screening process.

[0004] However, when the equipment is in use, the flow efficiency of the mud is low, which in turn affects the separation efficiency of iron or other impurities in the mud. Summary of the Invention

[0005] To address the above problems, this invention provides a slurry mixer for ceramic crafts. The mixer divides the vessel into an inner and outer layer. An outer stirring unit conveys the slurry from the outer layer upwards, while an inner stirring unit conveys the slurry from the inner layer downwards, allowing the slurry to circulate between the outer and inner layers. A filtration mechanism is positioned along the slurry's flow path to filter and clean it, thus solving the technical problem in existing technologies where low slurry flow efficiency leads to low impurity separation efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a clay mixer for ceramic crafts, comprising: a mixing vessel, the mixing vessel including a base and a vessel body mounted on the base, the top and bottom of the vessel body being respectively provided with a feed inlet and a discharge outlet; a mixing mechanism disposed within the vessel body, comprising an inner cylinder dividing the internal space of the vessel body radially into an inner layer and an outer layer, a plurality of external mixing units vertically rotatably mounted on the outer layer and arranged in a circumferential array, an inner mixing unit vertically rotatably mounted on the inner layer, and a power unit driving the external mixing units and the inner mixing units to operate simultaneously; and a filtering mechanism, the filtering mechanism including a filter screen unit disposed at the bottom of the inner cylinder; the upper and lower sides of the outer layer and the inner layer are in a connected state, the external mixing units conveying the clay upwards, and the internal mixing units conveying the clay downwards, so that the clay circulates between the outer layer and the inner layer, and the filtering components are disposed in the flow path of the clay to filter and clean the clay.

[0007] As an improvement, the cross-sectional area ratio of the inner layer to the outer layer is 4:3.

[0008] As an improvement, the external stirring unit includes a vertically rotating shaft a and a propeller blade a spirally arranged around the shaft a.

[0009] As an improvement, the external stirring unit also includes a mounting sleeve mounted on the rotating shaft a and located above the propeller blade a, and several sets of stirring rods arranged in a circumferential array on the mounting sleeve and forming a "D" shape with the outer wall of the mounting sleeve.

[0010] As an improvement, the internal stirring unit includes a rotating shaft b vertically rotatably mounted at the center of the vessel body and a propeller blade b spirally surrounding the rotating shaft b.

[0011] As an improvement, the power unit includes a mounting bracket disposed above the interior of the vessel body, a drive gear rotatably mounted on the mounting bracket and poweredly connected to the inner stirring unit, a driven gear poweredly connected to the corresponding outer stirring unit, several sets of transmission gears poweredly connecting the drive gear and the driven gear, and a motor disposed on the top of the vessel body and poweredly connected to the inner stirring unit.

[0012] As an improvement, the filter unit includes a filter support that is tapered and mounted at the bottom of the inner cylinder, and several sets of filter screens that are detachably arranged in a circumferential array on the filter support.

[0013] As an improvement, the filtration mechanism further includes an iron removal unit disposed on the filter screen unit and poweredly connected to the internal stirring unit.

[0014] As an improvement, the iron removal unit includes a mounting base detachably mounted on the filter unit, an upper shell detachably disposed from the internal stirring unit and rotatably sealed to the mounting base, a plurality of permanent magnet rods extending radially along the upper shell and arranged in a circumferential array, a bevel gear a mounted at the middle position of the mounting base, and a bevel gear b coaxially disposed with respect to the permanent magnet rods and poweredly connected to the bevel gear a.

[0015] As an improvement, the permanent magnet rod includes a rod body that is rotatably sealed to the upper shell and a plurality of side plates arranged in a circumferential array on the rod body and extending radially along the rod body.

[0016] The beneficial effects of the present invention are as follows: (1) The vessel body in the present invention is divided into an inner layer and an outer layer. The outer stirring unit conveys the mud in the outer layer upward, and the inner stirring unit conveys the mud in the inner layer downward, so that the mud circulates between the outer layer and the inner layer. The filtration mechanism is set on the flow path of the mud to filter and clean the mud, thereby improving the flow efficiency of the mud and thus improving the removal efficiency of impurities in the mud; (2) A permanent magnet rod that can rotate and revolve is set above the filter screen unit in the present invention. After the mud passes through the permanent magnet rod, the iron impurities in it are adsorbed, and at the same time, the mud above the filter screen unit generates a vortex, further improving the efficiency of the mud passing through the filter screen unit, thereby improving the filtration efficiency of other impurities in the mud; (3) The filter screen support in the present invention is set in a cone shape, and under the action of the vortex of the permanent magnet rod, the impurities filtered on the filter screen roll downward, ensuring that there is always an area on the filter screen that is not blocked by impurities, and once again ensuring the efficiency of the mud passing through the filter screen; (4) The filter screen in the present invention is detachable and can be replaced according to production needs, thereby improving the applicability of the equipment.

[0017] In summary, this invention has the advantages of simple structure, high mud filtration efficiency, and good mud filtration effect, and is especially suitable for the field of ceramic production technology. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] Example 1: As shown in Figures 1 to 3, a clay mixer for ceramic crafts includes: a mixing vessel 1, which includes a base 11 and a vessel body 12 mounted on the base 11. The top and bottom of the vessel body 12 are respectively provided with a feed inlet 121 and a discharge outlet 122; and a stirring mechanism 2, which is disposed inside the vessel body 12 and includes an inner cylinder 21 that radially divides the internal space of the vessel body 12 into an inner layer 1200 and an outer layer 1201, a plurality of external stirring units 22 that are vertically rotatably mounted on the outer layer 1201 and arranged in a circumferential array, and a stirring unit 22 that is vertically rotatably mounted on the inner layer 1201. The inner stirring unit 23 of the 1200 and the power unit 24 that drives the outer stirring unit 22 and the inner stirring unit 23 to operate simultaneously; and the filtration mechanism 3, which includes a filter screen unit 31 disposed at the bottom of the inner cylinder 21; the upper and lower sides of the outer layer 1201 and the inner layer 1200 are in a connected state, the outer stirring unit 22 conveys the mud upward, and the inner stirring unit 23 conveys the mud downward, so that the mud circulates between the outer layer 1201 and the inner layer 1200, and the filtration mechanism 3 is disposed on the flow path of the mud to filter and clean the mud.

[0024] It should be noted that the inner cylinder 21 is connected to the inner wall of the vessel body 12 via a mounting connecting plate.

[0025] Furthermore, the cross-sectional area ratio of the inner layer 1200 to the outer layer 1201 is 4:3.

[0026] It should be noted that, since the filter unit 31 is provided at the bottom of the inner layer 1200, the speed at which the mud passes through the filter unit 31 will be slowed down. In turn, by increasing the volume of the inner layer 1200, the mud is buffered, making the mud circulation smoother.

[0027] Furthermore, as shown in Figure 3, the external stirring unit 22 includes a vertically rotating shaft a221 and a propeller blade a222 spirally arranged around the shaft a221.

[0028] Furthermore, as shown in Figure 5, the external stirring unit 22 also includes a mounting sleeve 223 mounted on the rotating shaft a221 and located above the propeller blade a222, and a plurality of stirring rods 224 arranged in a circumferential array on the mounting sleeve 223 and forming a "D" shaped structure with the outer wall of the mounting sleeve 223.

[0029] It should be noted that the propeller blade a222 conveys the mud upwards, and the stirring rod 224 further disperses the mud, thereby enabling the mud to be better separated from the impurities therein.

[0030] It should also be noted that the rotating shaft a221 is mounted on the mounting connection plate of the inner cylinder 21.

[0031] Furthermore, the internal stirring unit 23 includes a rotating shaft b231 that is vertically rotatably installed at the center of the vessel body 12 and a propeller blade b232 that spirally surrounds the rotating shaft b231.

[0032] Furthermore, as shown in Figure 6, the power unit 24 includes a mounting bracket 241 disposed above the interior of the vessel body 12, a drive gear 242 rotatably mounted on the mounting bracket 241 and poweredly connected to the inner stirring unit 23, a driven gear 243 poweredly connected to the outer stirring unit 22, a plurality of transmission gears 244 poweredly connecting the drive gear 242 and the driven gear 243, and a motor 245 disposed on the top of the vessel body 12 and poweredly connected to the inner stirring unit 23.

[0033] It should be noted that the driving gear 242 is coaxially fixed with the rotating shaft b231, and the driven gear 243 is coaxially fixed with the rotating shaft a221.

[0034] It should also be noted that the motor 245 is poweredly connected to the rotating shaft b231; the motor 245 is mounted on the top of the vessel body 12 via a motor mounting bracket, and it is a three-phase asynchronous motor.

[0035] Furthermore, as shown in Figure 8, the filter unit 31 includes a filter support 311 that is conically mounted on the bottom of the inner cylinder 21 and several sets of filters 312 that are detachably arranged in a circumferential array on the filter support 311.

[0036] It should be noted that the filter support 311 is tapered so that the impurities attached to the filter 312 can move downwards, which can effectively prevent the impurities from accumulating on the filter 312 and ensure that there are always filter holes on the filter 312 for the mud to pass through.

[0037] It should also be noted that the filter screen 312 is detachable, making it easier to replace and clean, and the sieve holes on the filter screen 312 can be selected according to production needs.

[0038] Example 2: In this example, the same or corresponding components as in the above examples are referred to by the same reference numerals. For simplicity, only the differences from the above examples are described below. The difference between this example and the above examples is that, further, as shown in Figures 4 and 7, the filtration mechanism 3 also includes an iron removal unit 32 disposed on the filter screen unit 31 and poweredly connected to the internal stirring unit 23.

[0039] Furthermore, the iron removal unit 32 includes a mounting base 321 detachably mounted on the filter unit 31, an upper shell 322 detachably disposed from the inner stirring unit 23 and rotatably sealed to the mounting base 321, a plurality of permanent magnet rods 323 extending radially along the upper shell 322 and arranged in a circumferential array, a bevel gear a324 mounted at the middle position of the mounting base 321, and a bevel gear b325 coaxially disposed with respect to the permanent magnet rods 323 and poweredly connected to the bevel gear a324.

[0040] It should be noted that the upper shell 322 and the rotating shaft b231 are connected by a quick-connect convex-concave fit structure, and the mounting base 321 and the filter support 311 are connected by a quick-connect convex-concave fit structure, so that the iron removal unit 32 is a detachable structure, which facilitates the subsequent cleaning of the iron attached to the permanent magnet rod 323.

[0041] Furthermore, the permanent magnet rod 323 includes a rod body 3231 that is rotatably sealed to the upper shell 322 and a plurality of side plates 3232 arranged in a circumferential array on the rod body 3231 and extending radially along the rod body 3231.

[0042] It should be noted that the permanent magnet rod 323 can adsorb iron in the mud. The side plate 3232 increases the adsorption area and at the same time, the permanent magnet rod 323 generates eddies during its rotation and revolution. The eddies can move the impurities attached to the filter screen 312 downward and accelerate the speed at which the mud passes through the filter screen 312.

[0043] It should be noted that the interior of the vessel body 12, the surfaces of the parts that come into contact with the mud, or the parts at risk of contact with the mud, are all treated with anti-rust and anti-corrosion measures, and require regular manual maintenance.

[0044] Working process: The worker injects slurry into the vessel body 12 through the feed port 121. Then, the motor 245 drives the rotating shafts a221 and b231 to rotate. The propeller blades a222 and b232 drive the slurry in the vessel body 12 to circulate between the inner layer 1200 and the outer layer 1201. At the same time, under the driving action of the rotating shaft b231, the permanent magnet rod 323 rotates and revolves and adsorbs iron. When the slurry passes through the filter screen 312, the filter screen 312 filters impurities. After a period of circulation, the filtered and cleaned slurry flows out from the discharge port 122.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
